DETAILED DESCRIPTION

[0023] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0024] Embodiment 1

[0025] See also Figure 1-3According to an embodiment of the utility model, a hazardous solid waste leachate collection device comprises: three-stage collection devices 1, 3, 4, an exhaust pipeline 5 and a gas valve 6 connected in sequence through a transparent observation channel 2 provided with a conveying crawler 104, the collection devices 1, 3, 4 comprise an extrusion box 102 and a storage cabinet 7 connected up and down; a feed port 101 is provided at the top of the extrusion box 102, a filter screen is provided at the bottom of the extrusion box 102, a discharge port 105 is provided on one side of the extrusion box 102, and an exhaust pipeline 5 provided with a gas valve 6 is connected to the top of the extrusion box 102; the extrusion box 102 is provided with an opening below the filter screen, and the opening It is connected to the opening at the top of the storage cabinet 7 via a rubber seal; an upper door 702 and a lower door 704 are provided on one side of the outside of the storage cabinet 7, a ring beam is provided inside the storage cabinet 7 at a middle position between the upper door 702 and the lower door 704, a ring beam is provided on the ring beam, an annular cutter 703 is provided, an upper clamp and a lower clamp are also provided inside the storage cabinet 7, the lower clamp clamps and connects the liquid collecting bag 705; the inner diameter of the annular cutter 703 is larger than the outer diameter of the liquid collecting bag 705; a control box 706 is provided on the other side of the outside of the storage cabinet 7 for remote control of the upper clamp, the lower clamp and the annular cutter 703, and the control box 706 is controlled by a microcomputer via a servo mechanism.

[0026] Through the above scheme of the utility model, in specific applications, manual operation or remote computer operation is selected according to the hazard level of the waste. When the hazard level of the waste is low, people are allowed to operate the utility model at close range. First, turn on the power supply, use the lower clamp to clamp the liquid collection bag 705, and place it in a suitable position in the storage cabinet; use a forklift to pour the hazardous waste into the top of the squeezing box 102 of the collection device 1 connected to the feed port 101, and then use a stick or a pressing plate to squeeze the solid waste in the squeezing box 102, or let it stand and squeeze it by the gravity of the waste itself. During the feeding and squeezing process, open the gas valve 6, and the generated gas is discharged to the predetermined facility through the exhaust pipeline 5.

[0027] Under the squeeze action, the leachate inside the waste flows into the liquid collecting bag 705 in the storage cabinet 7, and the annular cutter 703 is used once on the liquid collecting bag 705 at regular intervals to cut off the suspended matter, flocculent matter, and colloid matter that descend with the leachate. Before the liquid collecting bag 705 collects to 80% of its capacity, it is ensured that the waste in the squeezing box 102 almost stops flowing out of the leachate. Then the waste enters the collecting device 2 3 through the discharge port 105, the conveying crawler 104, and the transparent observation channel 2. The shape of the waste, the leachate retention status, etc. can be viewed through the transparent observation channel 2. In the collecting device 2 3, the entire working process of the collecting device 1 is repeated until the liquid collecting bag collects to 80% of its capacity or the amount of leachate added in the liquid collecting bag within a predetermined time is less than a certain threshold. Then it enters the collecting device 3 4 through the discharge port, the conveying crawler, and the transparent observation channel of the collecting device 2 3, and repeats the above steps. It is worth pointing out that as the amount of leachate decreases, the amount of hazardous solid waste entering the collection device 3 4 can be several times the amount that initially enters the collection device 1, and its placement time can also be several times the length of time that the initial waste enters the collection device 1. After the leachate content of hazardous solid waste in the collection device 3 4 reaches the predetermined standard, subsequent solid waste treatment is carried out through its discharge port.

[0028] The liquid collection bag in the storage cabinet of the collection device is pushed out of the storage cabinet through the lower clamp in the storage cabinet and placed in a preset solid barrel for unified treatment after completion.

[0032] Through the above scheme of the utility model, in specific applications, manual operation or remote computer operation is selected according to the hazard level of the waste. When the hazard level of the waste is high, the operation of the utility model is remotely controlled. First, turn on the power supply, use a forklift to place the liquid collector 8 on the upper clamp in the storage cabinet 7, place the liquid collection bag 705 on the lower clamp in the storage cabinet 7, and place the square funnel card in the square opening at the top of the storage cabinet; use a forklift to pour the hazardous waste into the top of the extrusion box 102 of the collection device 1 connected to the feed port 101, and then use a stick or a pressing plate to squeeze the solid waste in the extrusion box 102, or let it stand and squeeze it by the gravity of the waste itself. During the feeding and extrusion process, open the gas valve 6, and the generated gas is discharged to the predetermined facility through the exhaust pipeline 5.

[0033] Under the squeeze action, the leachate inside the waste flows into the circular channel in the liquid collector 8 in the storage cabinet 7 through the square funnel. The leachate enters the liquid collection bag 705 through the diversion of the circular channel and the further isolation of the suspended matter, glue and floccules that flow with it by the connecting platform between the circular channels. The annular cutter 703 is used once on the liquid collection bag 705 at regular intervals to cut off the suspended matter, floccules, and glue that descend with the leachate. Before the liquid collection bag 705 collects to 80% of its capacity, it is ensured that the waste in the squeezing box 102 almost stops flowing out of the leachate. Then the waste enters the collection device 2 3 through the discharge port 105, the conveyor crawler 104, and the transparent observation channel 2. The shape of the waste, the retention status of the leachate, etc. can be viewed through the transparent observation channel 2. The entire working process of the collection device 1 is repeated in the collection device 2 3 until the collection bag collects to 80% of its capacity or the increase in the leachate in the collection bag within a predetermined time is less than a certain threshold. Then, it enters the collection device three 4 through the discharge port of the collection device two 3, the conveyor crawler, and the transparent observation channel, and repeats the above steps. It is worth noting that as the leachate decreases, the hazardous solid waste entering the collection device three 4 can be several times the amount that initially enters the collection device one 1, and its placement time can also be several times the length of time that the initial waste enters the collection device one 1. After the leachate content of the hazardous solid waste in the collection device three 4 reaches the predetermined standard, the subsequent solid waste treatment is carried out through its discharge port.

[0034] The liquid collection bag in the storage cabinet of the collection device is pushed out of the storage cabinet through the lower clamp in the storage cabinet and placed in a preset solid barrel for unified treatment after completion.
