Abstract

PURPOSE:To dehydrate a material, by constituting a device such that the material discharged from a classifier machine in a rubble work site or the like is transferred by a conveyer belt running diagonally upward and being vibrated. CONSTITUTION:A material discharged from a classifier machine B is delivered to a trough part 7. The material containing water on the trough part 7 is blocked by a skirt 25 and applied with vibration through a belt 6 of a belt conveyer vibrated by a vibrating bed 8 further moved to travel. In this way, water between material particles is driven out and accumulated in the inside of the skirt 25. In such way, the dehydrated material is conveyed upward by the belt 6 and discharged to a chute 55. By this constitution, the classified material containing water can be dehydrated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vibration dehydrator for further dewatering raw material discharged from a classifier, for example, in a gravel pit or a stone crushing plant.

Generally, a classifier is used at a gravel extraction site or a stone crushing site to wash and separate sand from the undiluted turbid water. When this is transported by truck or the like, water may leak from the loading platform onto the road, causing inconvenience.

For example, the classifier shown in Figure 4 (B) has turbid water inside the machine.
□, and the sand that has settled due to the difference in specific gravity is transferred by a spiral plate 6υ and discharged from the discharge port 52, but the discharged sand still contains a large amount of water. There is.

An object of the present invention is to further dehydrate raw materials containing water as described above.

In order to achieve this object, the present invention forms a machine part that receives and connects raw materials with a conveyor belt that is wound around a driving roller and a driven roller that are horizontally hung on the machine frame, and whose conveyance side moves diagonally upward. A vibratory dehydrator was constructed in which the dehydrator was supported by a vibrating table equipped with a vibrator.

Since the vibration dewatering machine of the present invention has the above-mentioned configuration, the raw material fed into the machine part is vibrated by the vibration table while being conveyed, and this vibration action causes the sand to become dense and there are gaps between the sand particles. The effect is that water is expelled and dehydrated sand is obtained.

The illustrated embodiment will be described below.

(8) is a vibration table, which has a substantially semi-cylindrical shape, and has a spring between the support plate f91 (bottom plate OI of 91... and the machine frame 11) fixed to its outer peripheral surface. α
υ... is interposed. Therefore, the shaking table (8
) is elastically attached to the machine frame tl+.

A vibration motor (13), which is a vibrator, is attached to the bottom of the vibration table (8) via a member a2 extending from the front and back of the bottom, and the rotation of this motor (13) causes the vibration table (8) to vibrate. It's like being forced to do something.

In the illustrated example, two vibration motors are installed, but the number of vibration motors is arbitrary depending on the size of the vibration table, and in the case of - two vibration motors, they are installed at the center of the bottom of the vibration table. Further, the member a2 is not necessarily required, and the motor may be directly attached to the bottom of the vibration table.

Furthermore, the vibration table (8) is supported by a support device 04) (b). The support device 0 has a rod a9 connected to the machine frame (the plate αη of the base Qf9 fixed on the cross beam a9 of 11) with QIDQ&, which is bored into a plate extending from the center of the outer circumferential surface of the vibration table (8). The rod I is inserted through the hole 0]1 (see Fig. 10) with some allowance, and a seat plate is attached to the rod I, and a seat plate is attached to the second seat plate). A spring is interposed between each plate (a) of the vibrating table (8) and the plate (a) of the vibration table (8).

This support device) (b) is for preventing the shaking table (8) from falling in the inclination direction, and the spring (
The vibration table (8) is elastically supported by the vibration table (8), and since there is a margin between the holes Q11 of the rods α9, the vibration of the vibration table is not hindered in any way. -,・.

The vibrating table (8) as described above supports the central part of the belt (6) on the conveyance side, and the belt (6) supports this vibrating table (8).
It is curved along the inner surface of the gutter 3 to form the gutter 3 part (7). In order to facilitate the shape and formation of this machine part (7), five rows of carrier rollers (C) (C) are arranged on the machine frame (1) on both the front and rear sides of the vibration table (8). ing.

Therefore, the driving roller (2) and the driven roller (3)
The belt (6) circulating between the belts (6) is flat on the non-conveyance side, and becomes gradually curved as it moves from the driven roller (3) to the 5-row carrier roller ψ' and the vibration table (8). This forms a machine part (7), and then it becomes flat again as it moves from the 5-row carrier roller (c) to the drive roller (2).

(c) is a skirt that is attached depending on the condition of the raw material, and is disposed below the machine part (7) and is in close contact with the inner surface of the mallet part. The skirt (c) is a rubber plate and is made thicker than the inner diameter of the machine part (7), so that the skirt edge slides into contact with the inner surface of the belt (6) to be transferred and is energized. and is curved toward the direction of belt movement.

Also, the upper edge of the skirt) is below the upper edge of the machine part.

) is the mounting angle of ) on the skirt.

As shown in Figures 12 and 13, this mounting angle is applied to the vertical member attached to the machine frame (C), to the vertical member (C), to the horizontal member suspended horizontally (C), and to this horizontal member. It consists of a skirt holder that is suspended from a (goods).

The skirt holder) consists of a member with a U-shaped cross section and three connecting members welded to it, and is a plate that is pressed by a bolt installed on the U-shaped member.
The upper part of the skirt (C) is inserted between the U-shaped member and the inner surface of the skirt (C). It can be installed by connecting the horizontal member (c) and the connecting member The mounting position of the skirt (c) can be adjusted up, down, left and right.

In addition, (37) is a drain plate installed at the rear end of the machine frame (1).
The drain plate H provided at the rear lower side of the machine frame is a water tank, the wheel is a motor that drives the drive roller (2), and the wheel is a walkway for when the vibration dehydrator breaks down.

Next, the operation of this vibrating dehydrator when Scar) H is attached will be explained.

In Figure 4, (B) is the classifier described earlier, which supplies turbid water into the machine, transfers sand that has settled to the bottom of the paper machine due to the difference in specific gravity with a spiral plate 6υ, and discharges it. It is designed to be ejected from the exit bag.

And this vibration dehydrator (A) has a discharge port 6 of a classifier (B).
The sand discharged from the six discharge ports is connected to the mallet part (7). Also,
The belt (6) is circulated by the drive of the motor, and the vibration table is vibrated by the rotation of the vibration motor (13 (+3).

First, when the sand (raw material) discharged from the discharge port 63 of the classifier is transferred to the mallet part (7), the mallet part (7) is inclined and this sand contains a lot of water. If there is, Tsuchibe (7
), but because of the presence of ) in the skirt, it is blocked as shown in Figure 5.

The vibration of the vibration table (8) is transmitted to the raw material via the belt (6), and the action of this vibration drives out the water between the sand particles, and the driven water flows into the skirt. ) is stored inside.

During this time, the belt (6) is in transition, whereby sand with a relatively low moisture content, ie dewatered sand 54), is transferred to the end of the conveyor, from where it is dumped onto the discharge conveyor through the chute. and transported to the appropriate location.

On the other hand, the water (g) stored inside the skirt (c) is
When the water surface exceeds the upper edge of the skirt, it overflows and flows over the heald (6) and from the bottom end of the conveyor to the water tank ←υ
to fall.

At this time, since there is a draining plate C17)■, water will not be scattered in the work area.

The water stored in the water tank ←υ is drained to an appropriate location by a pump (not shown).

As described above, the vibration dehydrator of the present invention can further dehydrate the sand discharged from the classifier.

The height of the skirt (c) depends on the amount of raw material processed.
Adjustments can be made using the elongated holes (to) on the skirt holder, and if the bolt nuts are properly warmed, the skirt can be moved left and right within the range of the elongated holes in the horizontal member (c).
It is possible to follow the meandering of the belt (6) in the left-right direction.

In addition, if the moisture content of the raw material is low, or if the slope of the conveyor is made small even if the moisture content is high, the sand will not flow down the conveyor even if the skirt is not installed. The water is conveyed below the conveyor, and the sand is conveyed above the conveyor.

Next, a second embodiment will be described.

FIG. 6 is a schematic front view showing a second embodiment of the vibration dehydrator of the present invention. The feature of this embodiment is that a flexible conveyor belt is used as the conveyor belt, and the structure of various parts is different from the first embodiment, so the differences will be explained in particular.
