Description

Technical Field

[0001] This utility model relates to the field of hazardous waste technology, specifically to a storage device for hazardous waste treatment. Background Technology

[0002] With industrial development, the amount of hazardous waste emitted during industrial production processes is increasing daily. It is estimated that the world generates 330 million tons of hazardous waste annually. Due to the severe pollution and potentially serious impacts caused by hazardous waste, it has been dubbed "political waste" in industrialized countries. The public is highly sensitive to the issue and opposes the establishment of hazardous waste disposal sites in their residential areas. Furthermore, the high cost of hazardous waste disposal has led some companies to actively seek to transfer hazardous waste to less developed countries and regions. Therefore, proper storage is essential during the disposal of hazardous waste.

[0003] However, existing storage devices directly place hazardous waste containing moisture into the water, which can easily cause safety hazards if the hazardous waste is soaked in water for a long time. At the same time, it is not convenient to compress the hazardous waste. The hazardous waste is relatively loose during storage, which takes up storage space and increases storage costs.

[0004] Therefore, it is necessary to modify it by setting up an extrusion structure to dehydrate the hazardous waste that needs to be stored, reduce the moisture content, shrink the volume of the hazardous waste and store it in a centralized manner, thereby improving space utilization and reducing storage costs. Utility Model Content

A push plate is located between the extrusion plate and the filter plate inside the treatment box. A horizontal plate is fixedly connected to the left side of the treatment box. A movable seat is slidably connected to the top left side of the horizontal plate. A forward and reverse motor is fixedly connected to the top of the movable seat. A first push rod is fixedly connected to both the front and rear sides of the left side of the push plate. The left end of the first push rod passes through to the left side of the treatment box and is fixedly connected to the movable plate. A screw block is fixedly connected inside the movable plate. A screw rod is threaded inside the screw block. The right end of the screw rod is rotatably connected to the left side of the treatment box.

The surface of the second cylinder is covered with a protective cover. The output end of the second cylinder extends through to the left end of the protective cover and is fixedly connected to a pull plate. The left end of the pull plate is fixedly connected to a sealing plate. The surface of the sealing plate is in contact with the inner wall of the discharge port.

[0008] As a preferred embodiment of this utility model, a second push rod is fixedly connected to both the front and rear sides of the lower right side of the movable plate. The right end of the second push rod penetrates into the interior of the treatment box and is fixedly connected to a brush plate. Both the front and rear sides of the brush plate are in contact with the inner wall of the treatment box, and the brush end of the brush plate is in contact with the bottom of the filter plate.

[0009] As a preferred embodiment of this invention, both the surface of the first push rod and the second push rod are slidably connected to a sealing piston, and the surface of the sealing piston is in contact with the inner wall of the processing box.

[0010] As a preferred embodiment of this utility model, a cleaning port is provided on the upper left side of the processing box, and a sealing cover is movably connected to the upper left side of the processing box by bolts, with the right side of the sealing cover fitting against the left side of the cleaning port.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a hazardous waste feeding device to add an appropriate amount of hazardous waste to be stored into the processing tank through the feeding port, causing the hazardous waste to fall above the filter plate. After feeding is completed, the first cylinder is activated, extending it and moving the right end of the extrusion plate downwards to compress the hazardous waste. The water contained in the hazardous waste flows to the bottom of the processing tank through the drain. When the first cylinder is fully extended, the left and right ends of the extrusion plate are aligned, allowing the hazardous waste to be dehydrated and compressed. Then, the sealing mechanism is opened, causing the sealing plate to move to the right and open the discharge port. The forward and reverse motors are then started to rotate forward, driving the... The screw rotates, causing the screw block and moving plate to move to the right. This causes the first pusher to push the push plate to move to the right, pushing the dehydrated and compressed hazardous waste to the right and dropping it through the discharge port into the collection box for centralized storage. Then, the first cylinder contracts, the forward and reverse motors reverse, and the sealing mechanism closes, resetting the device for the next operation. This achieves the effect of dehydrating hazardous waste that needs to be stored by setting up a compression structure, reducing the moisture content, compressing the volume of hazardous waste for centralized storage, improving space utilization, and reducing storage costs.

[0014] 2. This utility model utilizes a second cylinder, a pull plate, and a sealing plate in combination. When the first cylinder is activated to compress the hazardous waste, the sealing plate seals the discharge port, preventing water from flowing into the collection box. When it is necessary to discharge the compressed hazardous waste, the second cylinder is activated to retract, causing the pull plate and sealing plate to move to the right, opening the discharge port and facilitating the entry of the compressed hazardous waste into the collection box.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a storage device for hazardous waste treatment, including a treatment box 1. A collection box 2 is fixedly connected to the right side of the treatment box 1. Both the left side of the collection box 2 and the right side of the treatment box 1 have interconnected discharge ports 3. A sealing mechanism 4 is provided at the top inside the collection box 2.

The front, rear, and right sides of the pressing plate 5 are in contact with the inner wall of the treatment box 1. A hinge seat 6 is slidably connected to the top of the pressing plate 5. A first cylinder 7 is fixedly connected to the top of the treatment box 1. The output end of the first cylinder 7 extends into the interior of the treatment box 1 and is hinged to the interior of the hinge seat 6. A filter plate 8 is fixedly connected to the lower part of the interior of the treatment box 1. The surface of the filter plate 8 has a plurality of evenly distributed drain holes, and a filter screen is fixedly connected inside the drain holes. A filter screen is provided inside the treatment box 1 located between the pressing plate 5 and the filter plate 8. The push plate 9 between the plates 8 has its front and rear sides in contact with the inner wall of the processing box 1. A horizontal plate 10 is fixedly connected to the left side of the processing box 1. A movable seat 11 is slidably connected to the top left side of the horizontal plate 10. A forward and reverse motor 12 is fixedly connected to the top of the movable seat 11. A first push rod 13 is fixedly connected to the front and rear sides of the left side of the push plate 9. The left end of the first push rod 13 passes through to the left side of the processing box 1 and is fixedly connected to a movable plate 14. A screw block 15 is fixedly connected inside the movable plate 14. A screw rod 16 is threaded inside the screw block 15. The right end of the screw rod 16 is rotatably connected to the left side of the processing box 1. The left end of the screw rod 16 is fixedly connected to the output end of the forward and reverse motor 12. A drain valve pipe is connected to the lower front of the processing box 1 to facilitate the discharge of sewage from the bottom of the processing box 1. A feeding port is opened on the upper right side of the processing box 1. A sealed compartment door is hinged to the right side of the processing box 1 to facilitate the retrieval of stored hazardous waste.

[0022] refer to Figure 2 The sealing mechanism 4 includes a second cylinder 17 fixedly connected to the front and rear sides of the upper part of the collection box 2. The surface of the second cylinder 17 is covered with a protective cover. The output end of the second cylinder 17 extends through to the left end of the protective cover and is fixedly connected to a pull plate 18. The left end of the pull plate 18 is fixedly connected to a sealing plate 19. The surface of the sealing plate 19 is in contact with the inner wall of the discharge port 3.

[0023] As a technical optimization of this utility model, by setting up the second cylinder 17, the pull plate 18 and the sealing plate 19 for coordinated use, when the first cylinder 7 is started to squeeze the hazardous waste, the sealing plate 19 closes the discharge port 3 to prevent water from flowing into the collection box 2. When it is necessary to discharge the squeezed hazardous waste, the second cylinder 17 is started to contract, which drives the pull plate 18 and the sealing plate 19 to move to the right, opening the discharge port 3, so that the squeezed hazardous waste can enter the collection box 2.

[0024] refer to Figure 2 The front and rear sides of the lower right side of the movable plate 14 are fixedly connected to the second push rod 20. The right end of the second push rod 20 penetrates into the interior of the treatment box 1 and is fixedly connected to the brush plate 21. The front and rear sides of the brush plate 21 are in contact with the inner wall of the treatment box 1, and the brush end of the brush plate 21 is in contact with the bottom of the filter plate 8.

[0025] As a technical optimization of this utility model, by setting the second push rod 20 and the brush plate 21 to work together, when the forward and reverse motor 12 is started to rotate forward and drive the push plate 9 to move to the right, the second push rod 20 pushes the brush plate 21 to move to the right. The brush end of the brush plate 21 rubs against the surface of the filter plate 8 to clean the filter plate 8, thus avoiding the situation where the mesh of the filter plate 8 is blocked and affects its use.

[0026] refer to Figure 1 Both the first push rod 13 and the second push rod 20 are slidably connected to a sealing piston 22, and the surface of the sealing piston 22 is in contact with the inner wall of the processing box 1.

[0027] As a technical optimization of this utility model, by setting a sealing piston 22, the gap between the first push rod 13 and the second push rod 20 and the contact surface of the treatment box 1 is sealed, thus preventing wastewater from flowing out of the gap during use and affecting the normal use of the device.

[0028] refer to Figure 1 A cleaning port is provided on the upper left side of the treatment box 1. A sealing cover 23 is movably connected to the upper left side of the treatment box 1 by bolts. The right side of the sealing cover 23 fits against the left side of the cleaning port.

[0029] As a technical optimization of this utility model, by setting a sealing cover plate 23, when the device is used for a long time, hazardous waste may fall to the left side of the extrusion plate 5. By loosening the bolts and removing the sealing cover plate 23, the hazardous waste that has fallen to the left side of the extrusion plate 5 can be cleaned up, thus avoiding the accumulation of hazardous waste on the left side of the extrusion plate 5 and affecting the normal use of the device.

[0030] refer to Figure 4 The bottom of the hinge seat 6 is fixedly connected to a T-shaped block 24, and the top of the extrusion plate 5 is provided with a T-shaped groove 25 that cooperates with the T-shaped block 24. The surface of the T-shaped block 24 is slidably connected to the inner wall of the T-shaped groove 25.

[0031] As a technical optimization of this utility model, by setting the T-shaped block 24 and the T-shaped groove 25 in cooperation, when the first cylinder 7 extends and retracts, the hinge seat 6 slides left and right on the top of the extrusion plate 5, and the T-shaped block 24 slides inside the T-shaped groove 25, which plays a role in limiting and reinforcing the hinge seat 6, so that it can only move left and right on the top of the extrusion plate 5, thus preventing the hinge seat 6 from falling off and affecting the normal use of the device.

[0032] The working principle and usage process of this utility model are as follows: Hazardous waste to be stored is added to the processing tank 1 in appropriate amount through the feeding port using a hazardous waste feeding device. The hazardous waste falls onto the filter plate 8. After feeding, the first cylinder 7 is activated, extending it and causing the right end of the extrusion plate 5 to move downwards, compressing the hazardous waste. The moisture contained in the hazardous waste flows down into the processing tank 1 through the drain. When the first cylinder 7 is fully extended, the left and right ends of the extrusion plate 5 are aligned, allowing the hazardous waste to be dehydrated and compressed. Then, the sealing mechanism 4 is opened, causing the sealing plate 19 to move to the right and open the discharge port 3. The forward and reverse motors 12 are then activated to rotate the discharge port forward and reverse. The rotating screw 16 drives the screw block 15 and the moving plate 14 to move to the right, causing the first push rod 13 to push the push plate 9 to move to the right. This pushes the dehydrated and compressed hazardous waste to the right and drops it into the collection box 2 through the discharge port 3 for centralized storage. Then, the first cylinder 7 retracts, the forward and reverse motor 12 reverses, and the sealing mechanism 4 closes, resetting the device for easy operation. This achieves the effect of dehydrating the hazardous waste that needs to be stored by setting up a compression structure, reducing the moisture content, compressing the volume of the hazardous waste for centralized storage, improving space utilization, and reducing storage costs.
