Description

[Detailed description of the invention] <Industrial application field> This invention 1! Jl relates to a device that turns into a cake and disposes of foreign matter that flows into a sewage treatment pipe in a sewage treatment plant or the like and that enters a human waste temporary receiving tank in a human waste treatment plant.

Problems to be Solved by the Invention: Sewage flowing into a sewage treatment plant is contaminated with human sludge, and human waste transported to the human waste treatment plant is contaminated with foreign matter. Conventionally, these residues,
The impurities are passed through a flow path or suction pipe, and are thrown into a cylinder with a built-in screw shaft, separated from sewage, sewage, and human waste, and then disposed of. These metals may come into contact with the diaphragm blades of the screw shaft and break them, resulting in jamming and clogging.
There was a problem in that the work was often interrupted; and since the waste squeezed out from the cylinder was slow, there was a problem in that it contaminated the surrounding area when being transferred to a transport vehicle or the like.

The present invention solves these problems by compressing the residue and impurities into a cake to reduce the amount and efficiently dispose of it. A housing with an inlet chute installed on one side of the upper surface for receiving impurities in human waste and urine is fixed on the top.
A washing jacket ht is provided to wash the residue and impurities that are introduced into the intermediate wall I on the input chute side of the casing and the inner surface of the input chute, and the washed residue is installed inside the casing.

A sliding press mechanism consisting of a press plate with many through-holes and a back plate that turns impurities into a cake while dehydrating them is installed facing each other in the housing, and the residue is turned into a cake on the other side of the housing, This device is equipped with a pusher mechanism for dropping foreign matter onto a conveyor placed under the casing.

As described above, the residue and impurities that are put into the housing are washed by the supply of washing water to remove the sludge, and then dehydrated and coupled, so they are sufficiently solidified under relatively small pressure. In order to be crushed by the cake,
(This will not cause any of the problems seen on the screw shaft.)
However, by turning the residue and impurities into a cake and disposing of them, the amount can be reduced, the disposal efficiency can be improved, and the disposal environment can be improved. Furthermore, it is possible to eliminate the contamination of the surrounding area when transferring it to a transport vehicle or the like.

Detailed Description of the Invention (Field of Industrial Application) This invention is a method for cleaning and dewatering human waste flowing into a sewage treatment pipe in a sewage treatment plant or impurities mixed in a human waste temporary receiving tank in a human waste treatment plant. Concerning equipment to be disposed of. Problems to be Solved by the Invention: Sewage flowing into a sewage treatment plant is contaminated with human sludge, and human waste transported to the human waste treatment plant is contaminated with foreign matter. Conventionally, these sludge or impurities have been sequentially introduced into a cylinder with a built-in screw shaft through a flow path or suction pipe, and then squeezed and separated from the sewage or human waste and disposed of. Contaminants may contain metals, and these metals may break or become stuck in the throttling blades of the screw shaft, causing clogging. There was a problem that work was often interrupted. Moreover, especially when it comes to human waste, there is a problem in that the waste squeezed out of the cylinder cannot be removed and therefore stains the surrounding area when being transferred to a transport vehicle.90 The present invention solves these problems. In addition to solving this problem, the waste residue or impurities are washed, compressed, and dehydrated to reduce the amount of residue and impurities so that they can be efficiently disposed of. <Structure of the Invention> The present invention fixes a casing provided with an inlet chute on the upper surface of one side for receiving human sludge in sewage or impurities in human waste on a frame, A washing jacket is provided to wash the sludge or impurities that are introduced into the wall painting and the inner surface of the input chute, and a press with many through holes is installed in the housing to dehydrate the sludge or impurities that have been washed. A sliding type press mechanism consisting of a plate and a back plate is installed facing each other in the housing, and the dehydrated residue or impurities on the other side of the housing is dropped onto a conveyor disposed below the housing. It is equipped with a ninth pushing body mechanism. As described above, the residue or impurities that are introduced into the housing are washed by the supply of washing water to remove the sludge, and then dehydrated and cooled, so that the solid and liquid particles are sufficiently solid-liquid at a relatively low pressure. It can be separated as residue or impurities, and even if hard materials such as metals are mixed in during the press, they are collected on the screw shaft to prevent them from being gathered between the press plate and the back plate. However, by washing, dehydrating, and disposing of the residue or impurities, the amount can be reduced, the disposal efficiency can be improved, and the disposal environment can be improved. In addition, it is possible to eliminate contamination of the surrounding area when transferring it to a transport vehicle or the like.<Embodiment> An embodiment will be described below based on the drawings.

Reference numeral 35 is an outlet for discharging the residue etc. The device of the present invention is installed in a sewage flow path such as a sewage treatment plant, or a sludge discharge conveyor, or a suction pipe or scraping mechanism for human waste in a temporary storage tank of a sewage treatment plant or sediment in a storage tank. (not shown). The human waste is guided onto the input chute 14 of the apparatus of the present invention by these human waste conveyor or by a suction or scraping mechanism for the foreign matter in the human waste. The device of the present invention is advanced to the inner end position of the bank plate 24t-pushing mark 26, and the washing water supplied through the water supply pipe 18 is injected into the base inner surface of the rotor 5-5 and the casing through the washing jackets 17m and 17t+. Water is sprinkled below the receiving port 13 of the body 12, and the sludge or impurities that are thrown in are received into the housing 12 through the feeding port chute 14t. When the amount of input reaches the amount that blocks the receiving port 13, the input is temporarily interrupted. The input residue or impurities are thoroughly washed when passing through the input tube 14t and inside the housing 12, but are removed along with washing water into the pores 15 directly below. It flows into the hopper-shaped receiver 16 through the construction surface. Next, the pressurizing cylinder 20a is operated to operate the breath plate 23 to move the breath plate 23 forward, and the water in the residue or impurities is passed through the through holes 22 and dehydrated while the back plate is being dehydrated. After applying pressure to the 24th side,
The residue or impurities are put into the sealed part between the socket 13 and the pusher 26 in the housing 12 and are made into a dehydrated residue a. Since glue has been removed and dehydration is performed without washing or pressurizing, solid-liquid separation is sufficient to form a dehydrated residue a. Next, the dewatered residue a is guided below the inlet 26 by the movement of both plates 24, and is pushed by the pushing body 3 which is lowered by the operation of the motor. It passes through chute 32t and falls onto conveyor A, where it is collected for disposal. Incidentally, the separated liquid generated during the dehydration process passes through the surface of the pore 15 and is collected into the hopper-shaped receiver 16, similar to washing water and the like. The dewatering residue a is deposited on the belt conveyor, and the press plate and pack plate are returned to their original positions in preparation for the next washing and dewatering operation. <Effects of the Invention> As described above, the present invention cleans the residue or impurities introduced into the casing to remove so-called sludge, and then dehydrates it. The dehydrated residue a can be sufficiently solidified by applying relatively low pressure. By washing and dewatering, the amount of waste to be discarded can be reduced to a significantly smaller amount than the amount of residue or impurities, which makes the disposal work more efficient. It also has the effect of eliminating contamination of the surrounding area when transferring to a transport vehicle for disposal. Furthermore, it has the effect of improving the environment by promoting the treatment of sludge and other impurities that accumulate in sewage and human waste treatment plants.
