Abstract

PURPOSE:To improve the filtration performance of the titled dehydrator and to reduce the clogging by pressing and dehydrating the material to be treated by a brush which is circulated and moved after filtration on a screen and the synchronized rollers provided on an under the brush to dehydrate water, submerging and moving the brush in a washing water tank to clean the brush. CONSTITUTION:The filter body of a brush 2 fixed to a stage member 4 with the brush material as the filter medium directly under a tubular inlet 1 formed at the upper part is fixed by successively superposing the front and rear ends of the brush 2 to an opposite chain 5. The filtered water is charged in a treated water tank 8, and discharged from a water discharge port 9. After filtration, the chain 5 moved into a washing water tank 17 is loosened, hence the brush 2 is hung and moved, the brush is cleaned by a brush vibrating member 23 fixed at the lower part of the washing water tank 17, the brush 2 is vertically raised and drained, and the brush is again used for filtration.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a brush screen dewatering device in which a roller dewatering device is attached to a screen device using a brush as a furnace body.

(Prior Art) Generally, a screen device and a dewatering device each have a dedicated function. The F body is operated by installing a metal plate, wire mesh, or furnace cloth with many slits and furnace holes on a slope, or by circulating it. In particular, dewatering equipment uses a net or furnace cloth as a belt, and moves the captured material endlessly around a number of rollers.
This is a device that compresses and dehydrates water using its tension and rollers.

(Problems to be Solved by the Invention) In both the screen device and the dewatering device, the F eyes of the F body are jammed due to the formed foot openings, and the finer the eyes, the more they become clogged and the temporary capacity decreases. Since the dewatering device squeezes the furnace cloth together with the captured material, the residue gets stuck in the F holes and causes them to become clogged. In addition to requiring human labor to remove it, there is also a cleaning device that uses high-pressure clean water, but it is difficult to completely remove it, so the dehydration ability is reduced.

In addition, there are difficulties in replacing the long furnace cloth. The wastewater filtration and separation device (Japanese Patent Publication No. 60-038967) has the disadvantage of having a dehydration device and a washing tank. The present invention aims to solve these problems with conventional screen devices and dewatering devices.

(Means for Solving the Problems) The device according to the present invention is particularly concerned with improving the wastewater-permeation separation device, and improves the filtration performance required for this device, and the device is equipped with a dewatering device and a push-cleaning water tank. It is.

After filtration with a screen, a brush that circulates and moves, and rollers installed above and below the brush in synchronization, compresses and dehydrates the water and discharges it.Furthermore, the brush is immersed in a washing water tank for cleaning.

Since the brush door body can be used by mixing P materials of different types of brush materials or by stacking each layer, the device is capable of fine solid-liquid separation and does not clog the shield.

(effect) The invention will be explained with reference to the drawings.

A brush 20 fixed to a base member 4 using a brush material 3 as a furnace material is placed directly below the tubular accommodation port l formed in the upper part in FIG.
The F body is a brush circulation door body in which the front and rear ends of the brushes are stacked one after another on the opposing chain 5. Due to the tension of the chain, the tips of the brushes on the rail 6 press against the lower brushes. They stick together to make filtration effective. Depending on the brush material 3, the chain 5 between each brush is provided with a reinforcing member 7. The filtered treated water is received in a treated water tank 8 provided inside the brush circulation and flows out from a drain port 9. A roller 11 having a gap on the outer periphery for accommodating a stand member and a dewatering member is fixed to a shaft 10 installed at the upper part of the treated water tank, and a chain foil 13 for circulating brushes is attached to the outside of both ends of the roller 11. , and motor 1 on the outside.
A chain wheel 16 transmitted by a chain 15 from 4 is fixed, and the brushes are moved in circulation. After filtration,
As the chain moved into the sediment tank 17 loosens, the brush hangs down and moves, and is cleaned by the brush vibrating member 23 fixed to the bottom of the washing tank, and then the brush rises vertically to drain water and filter again. .

The above-mentioned roller 11 and the upper roller 12 via the brush
are attached to the mounting portions 18 at both ends thereof, so that they can be adjusted up and down. In addition, in order to synchronize the rotation of the upper roller 12 with the circulation movement speed of the brush, the rotation of the motor is reversed by a belt or gear 19L, and a chain 20 is used.
The power is transmitted to the chain wheel 21 fixed to the upper roller 12.

The brush received by the lower roller 11 and the captured material squeezed by the upper roller 12 exit to the bird-shaped part 22 for discharge. Arrows indicate the direction of rotation.

(Example) The present invention is a brush, and the furnace material uses the material of the brush.
Use metal wire, chemically synthesized wire, or vegetable fiber.

Also, those processed into waveforms or spirals are also used.

The above materials may be mixed or used in layers.

As an example, a door body can be used which has two layers: an upper layer of processed stainless steel fine wire and a lower layer of processed chemically synthesized wire.

It is a comb-shaped door body with a slightly thick wire fixed to a base member.

The above door bodies can also be used when installed in parallel.

Use the required number of brush circulation rollers at ℃.

The rollers installed on the top of the brush should be placed in the required number rather than individually.

An IN system in which an endless band-like member is connected to the brush and rotates, or a width belt is circulated by driving wheels or rollers provided at the front and back of the inside of the belt.

A device with rollers placed in the above circulation.

A device that moves a flat plate or uneven member on the top of the brush up and down or back and forth.

needle A compression dehydration device with the above device installed on the bra.

Water supply and drainage of the cleaning water tank is automated using a timer switch and pump.

, ;, This is a device that is equipped with 5 and 2 J-positions.

(Effects of the invention) The combination of various F materials improves the filtration ability, and since the captured substances are dehydrated before they change in quality, subsequent processing can be done rationally, and the beneficial effects of water used in various industries can be improved. It is an economical small-sized device that can perform solid-liquid separation for multiple purposes such as material recovery and wastewater treatment.
