Description

[Detailed description of the invention] The present invention relates to a hopper equipped with a dewatering device, and is characterized in that the hopper is equipped with a dehydrating device, and can be used to transport municipal waste, activated sludge sludge, etc., and other transport means. Prior to transportation, the water-containing waste is stored in a hopper and can be dehydrated while being piled up, which shortens processing time, prevents the transportation means from being contaminated and corroded by water, and prevents water from being transported to roads, etc. This prevents the leakage of water droplets and contributes to maintaining the aesthetic environment of the city.

That is, the hopper with a dewatering device of the present invention has a storage hopper with a bottom-shaped cross-section supported on the ground, separating a space in which a transportation means such as a truck enters and exits downward, and a storage hopper with a cross section shaped like a ship's bottom that is symmetrically partitioned by a partition wall. a distributing device for alternately distributing water-containing waste to the left and right chambers; a filter segment consisting of a filter cloth and a filtrate outlet and fixed to the outside of the chamber; A bottom segment that is constructed of a filter cloth and a filtrate outlet in the same way as the segment, and is provided continuously to the filter segment at the bottom of the chamber so as to be openable and closable, and a piston cylinder that opens and opens the bottom segment from side to side. piping connected to each of the filtrate outlets to discharge moisture; a storage pit to collect the moisture discharged by the piping; a backwash water line connected to the piping to cause wash water to flow back into the filter cloth; A level detection device detects the upper limit of waste accumulated in the room and switches and controls the distribution device.

Next, details of one embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is an explanatory diagram of a hopper with a dewatering device according to the present invention, in which a storage hopper 17 having a ship bottom-shaped cross section is provided in a support structure 16. The hopper is symmetrically divided into two left and right chambers by a partition wall 3. Each chamber has a filter segment 4 and a bottom segment 5. The filter segment 4 is fixed, and the bottom segment 5 can be opened left and right about the shaft 18 by actuation of hydraulic and pneumatic pressure of the piston cylinder 9.

1 is a conveyor belt running in the direction of the arrow for transporting water-containing waste such as municipal waste to the hopper equipped with a dewatering device of the present invention. 2 is a distribution device that rotates around 22 in the direction of the arrow, and rotates left and right at regular intervals to distribute water-containing waste to left and right hoppers, respectively. The filter segment 4 and the bottom segment 5 each have a structure as seen in FIG. That is, as shown in FIG. 2, it has filter segments collectively referred to as 4, with filter crosses 4a,
Filter cloth presser frame 4b, packing 4c,
It consists of a water outlet 4d, a filter cloth support rod 4e, and a segment holding bolt 4f, and the moisture of the water-containing waste accumulated and stored in the hopper 17 is dehydrated from the filter cloth 4a, discharged from the water outlet 4d, and water is passed through the piping 20. It is collected in a storage pit 14. Reference numeral 11 denotes an on-off valve, and by closing this and opening the on-off valve 21, wash water is supplied from the backwash water line 12 to the filter segment 4.
The water flows back into the interior and washes the filter cloth 4a.

A portion of the water, wash water, is collected in the gutter 8 and conduit 2
3 and collected in a storage pit 14. Reference numeral 15 denotes a stored water sending pump, which returns the stored water and washing water to the raw water line, where it is treated and reused. 13 is a path of the truck, and when the truck is stopped, the aforementioned bottom segment 5
When the is opened, the dehydrated waste is loaded onto the truck and carried out of the apparatus. Reference numeral 10 denotes a level detection device which detects the upper limit of waste 6 deposited in the hopper 17 and switches and controls the upper hopper input switching device 2.

(1) The storage hopper is shaped like the bottom of a ship, and the interior is partitioned with partition walls to form bilaterally symmetrical chambers, so that the water-containing waste is alternately distributed by a distribution device. The water-containing waste is stored in a compressed state and the moisture is squeezed out, and while the waste is being dehydrated in one room, it is being loaded onto trucks and put into the hopper in the other room, so that the entire waste is This allows you to work efficiently.

(2) A filter segment is fixed to the outside of the chamber, and a bottom segment is provided at the bottom of the chamber continuously from the filter segment so as to be openable and closable, and the bottom segment is operated to open left and right by a piston cylinder. Therefore, the dewatering area can be increased while maintaining the structural strength of the device, and the dewatering efficiency can be improved.

(3) The filter segment and the bottom segment are composed of a filter cloth and a filtrate outlet, and piping is connected to each filtrate outlet to collect water into the storage bit, so that the dehydrated water can be scattered around. It can be collected cleanly without any problems.

(4) Since a backwash water line is connected to the piping to allow the washing water to flow back into the filter cloth, the filter cloth can be easily and quickly washed using the piping.

(5) Since the upper limit of the waste accumulated in the room is detected by the level detection device and the distribution device is switched and controlled, the waste can be reliably and efficiently thrown into the hopper.
