Description

[Detailed description of the invention] The present invention relates to a dewatered sludge transport device.

To transport dehydrated sludge cake from a wastewater treatment facility such as a secondary building or building, a steel tower is built outside and a cake hopper is installed, the cake is stored in the cake hopper as appropriate, and a dump truck is placed directly below the cake hopper. The dumper enters the dump truck, opens the damper at the bottom of the cake hopper, loads the cake into the dump truck, and transports it out.

However, with this type of method, there are major restrictions on equipment space, and there is also the problem of bad odors caused by water droplets falling from the cake hobber and falling sludge.

The present invention seeks to obviate such prior drawbacks.

The illustrated embodiment will be described below.

In Fig. 1, "1 is a centrifugal dehydrator for sludge in the wastewater treatment facility of Bilding. This dehydrator dehydrates excess sludge from sewage to a moisture content of 85% or less and turns it into a cake.

2 is a belt conveyor that receives and conveys the cake from the dehydrator 1, 3 is a cake hopper (approximately 5 mm) that receives and stores cake from the belt conveyor 2, and 4 is installed at the bottom of the cake hopper 3. The cake transfer pump sequentially pumps the cake in the cake hopper 3.

6 is a cake transfer pipe connected to the cake transfer pump 4;
A valve 51 is provided midway to transfer the cake from the cake transfer pump.

The cake hopper 3 having the dehydrator 1, the belt conveyor 2, the cake transfer pump 4, etc. described above is installed in a basement in the building, and the cake transfer pipe 5 is installed as appropriate inside the building, and its end 52 is installed in the basement. Appropriate location near building outer wall 8 (Figure 2)
It is located in

Reference numeral 6 denotes a cake discharge pipe connected to the cake transfer pipe end 52, and the cake discharge pipe is extended through the outer wall 8 of the building, and as it is delivered, it is abutted against and connected to the pipe end 52. Ru.

More specifically, as shown in FIGS. 2 and 3, a window hole 81 is formed in the outer wall 8 of the building, and the cake discharge pipe 6 is guided diagonally downward through the window hole 81. , the frame bodies 63, 63 are fixed to the building outer wall 8 and the building proper place 9, and the receiving rollers 64, 64 are rotatably supported on the frame bodies 63, 63, and the cake discharge pipe is mounted on the receiving rollers 64, 64. 6 is movably placed on the cake discharge pipe 6, guide rails 65, 65 are placed along both sides of the cake discharge pipe 6, and the guide rails 65, 65 are engaged with grooves 66, 66 formed in the frames 63, 63, so that the cake discharge pipe 6 A feeding mechanism 7 is engaged with a rack 67 on the upper surface of the front half of the cake discharge pipe 6, and the feeding mechanism 7 is equipped on the inner surface of the building outer wall 8 and has a pinion 71 that meshes with the rack S7; A rotating shaft 73 to which the pinion TI is fixed and supported in a frame 72 mounted on the outer wall 8 of the building, and a chain wheel 74 fixed to the core rotating shaft 73.
, another chain wheel 75 that is appropriately supported on the inner surface of the outer wall 8 of the building in correspondence with the chain wheel 74; It consists of a manual rotation device 77 and a cover 78 that covers at least the upper part of the feed mechanism.
, the pinion 71 is rotated via the rotating shaft 73, thereby moving the rack 67, and the cake discharge pipe 6 is drawn out and drawn in as described above. In addition, a socket 61 is erected from the rear upper surface of the cake discharge pipe 6, and the socket 61 is
The end surface of the mouth end 62 of the cake transfer pipe 6 is formed into a slope facing forward and upward, and the end surface of the cake transfer pipe end 52 is formed into a slope corresponding to the end surface of the mouth end 62. The end 62 of the cake transfer pipe hits the end 52 of the cake transfer pipe so that both pipes 5 and 6 are closed, and the rear end 68 of the cake discharge pipe 6 is closed.
A door 83 is pivotally attached to the upper edge of a window hole 811 on the outer surface of the outer wall 8 of the building, and the door is automatically opened and closed when the cake discharge pipe 6 is moved in and out.

68 is a cap attached to the front end of the cake discharge pipe 6.

Then, as shown in FIG. 4A, Shindan pulls the cake discharge pipe 6 into the building and stores the cake in the cake hopper 3 as appropriate.

When there are too many cakes in the cake hopper 3, the dump truck is parked under the window hole 81 of the outside light 8 of the building, and the cake discharge pipe 6 is passed through the window hole 81 and steered toward the outside wall of the building, as shown in Figure 4-B. and the receiving end 62 of the cake discharge pipe 6.
is brought into contact with the end 52 of the cake transfer pipe Ei, and the cake transfer pump 4 is operated to transfer the cake to the cake hopper 3.
The inner cake is loaded onto a dump truck via a cake transfer pipe 5 and a cake discharge pipe 6.

When this is completed, as shown in FIG. 4C, the cake discharge pipe 6 is retracted into the building, and the cake is transported by dump truck to a predetermined location and dumped.

In addition, although the water pipe 10' is shown in FIG. 1 and is intended to clean the inside of the water pipe, it may be provided as appropriate as required.

According to the present invention, since the cake hopper can be installed at any suitable location within the building, such as in the basement, it is possible to solve the conventional problems such as the generation of odors due to location constraints, and all the equipment can be installed within the building. It is convenient in terms of design and environment.

In addition, the cake ejection pipe is only brought out when necessary, and the Shindan pipe is retracted into the building, so it does not interfere with traffic or work outside the building, and surplus space can be used effectively. It works extremely well on a toss base.
