Description

Technical Field

[0001] This utility model relates to the technical field of hazardous waste storage devices, specifically a hazardous waste storage device with an explosion-proof structure. Background Technology

[0002] Hazardous waste refers to solid waste with hazardous characteristics. These wastes are listed in the National Hazardous Waste List or identified as having hazardous characteristics according to the national hazardous waste identification standards and methods. If hazardous waste is directly discharged into the natural environment, it will cause serious pollution to the natural environment. In daily life, it is often stored. However, some hazardous wastes are more reactive and are prone to explosion. Therefore, a hazardous waste storage device with an explosion-proof structure is proposed to store them.

[0003] A hazardous waste storage device disclosed in the authorization announcement number CN214690889U includes a box, a placement rack, storage barrels, a drive assembly, and a ventilation assembly. The box has an inlet, and a door is rotatably connected to the box to close the inlet. The placement rack is located inside the box, and multiple storage barrels are provided and placed on the placement rack. The drive assembly is used to move the storage barrels, and the ventilation assembly is used to enhance the airflow exchange between the box and the outside.

[0004] Although it achieves the goal of simply loading hazardous waste into a storage bin, placing the storage bin on a rack, and then having the drive assembly move the rack to move the storage bin into the container, this application has the effect of reducing secondary pollution to the surrounding environment during the storage of hazardous waste.

[0005] However, the existing hazardous waste storage devices do not solve the problems of inconvenient linkage opening and closing of explosion-proof covers and central positioning clamps to prevent hazardous waste bins from shaking during use, nor do they facilitate the lifting of the placement plate for workers to place hazardous waste bins, thus affecting the safety of hazardous waste storage. Utility Model Content

[0006] The purpose of this utility model is to provide a hazardous waste storage device with an explosion-proof structure to solve the problems mentioned in the background art, such as the inconvenience of the linkage opening and closing of the explosion-proof cover and the central positioning clamping of the hazardous waste bin to prevent the hazardous waste bin from shaking, the difficulty in raising the placement plate to facilitate workers to place the hazardous waste bin, and the impact on the safety of hazardous waste storage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hazardous waste storage device with an explosion-proof structure, comprising an explosion-proof tank and a hydraulic cylinder. The hydraulic cylinder is movably mounted on the outer wall of the explosion-proof tank. A push arm is mounted on the output end of the hydraulic cylinder. A linkage arm is provided at the end of the push arm away from the hydraulic cylinder. A hinge shaft is provided on the side of the linkage arm near the push arm, and the linkage arm is movably connected to the push arm through the hinge shaft. An explosion-proof cover is mounted on the side wall of the linkage arm. A linkage shaft is provided at the end of the linkage arm near the explosion-proof tank, and the linkage arm is movably connected to the explosion-proof tank through the linkage shaft. Four sets of integrated frames with equal spacing are installed on the inner wall of the explosion-proof tank. A placement plate is provided inside the explosion-proof tank.

[0008] Preferably, each integrated frame has a lead screw movably installed inside, and each integrated frame has a lifting motor installed at its top, with the output end of the lifting motor connected to the lead screw.

[0009] Preferably, the surface of the lead screw is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the lead screw, and the threaded sleeve is connected to the placement plate.

[0010] Preferably, the top of the placement plate is equipped with multiple sets of placement seats at equal intervals, and a central column is installed at the center of each placement seat.

[0011] Preferably, each of the central columns is slidably mounted with a sleeve, and each sleeve is equipped with multiple sets of springs at equal intervals at its bottom end, and the springs are connected to the placement seat.

[0012] Preferably, each sleeve has three sets of equally spaced sliding rods on its side wall, each sliding rod has a movable shaft at the end near the sleeve, and the sliding rod is movably connected to the sleeve through the movable shaft, and each sleeve has a bearing plate installed at its top.

[0013] Preferably, the outer wall of the placement seat is provided with three sets of clamping arms at equal intervals, the side wall of each clamping arm is equipped with a connecting shaft, and the clamping arm is movably connected to the placement seat through the connecting shaft, and the clamping arm is slidably connected to the slide rod.

[0014] Preferably, each clamping arm has a clamping block at its top end, and each clamping block has a pin installed on its side wall, and the clamping block is movably connected to the clamping arm through the pin.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the hazardous waste storage device not only realizes the convenient linkage opening and closing of the explosion-proof cover and the central positioning clamping of the hazardous waste bin to prevent the hazardous waste bin from shaking, but also facilitates the lifting of the placement plate to make it easier for workers to place the hazardous waste bin, and improves the safety of hazardous waste storage.

[0016] (1) The device is made of high-strength explosion-proof steel and has explosion-proof function. When it is necessary to store hazardous waste, the hydraulic cylinder drives the push arm to move, the push arm drives the linkage arm to rotate around the linkage shaft through the hinge shaft, the linkage arm drives the explosion-proof cover to rotate, and the explosion-proof cover is opened by the lifting motor driving the screw to rotate, the screw drives the placement plate to move upward through the threaded sleeve, and the placement plate drives multiple sets of placement seats to move upward, so that the placement seats are moved to the position of the explosion-proof tank opening, so that workers can place the hazardous waste bins on the bearing plate, avoid workers bending over to operate, reduce the probability of workers being injured, realize convenient linkage opening and closing of the explosion-proof cover, and facilitate the lifting of the placement plate to facilitate workers to place the hazardous waste bins.

[0017] (2) By placing the hazardous waste bin on the support plate, the hazardous waste bin drives the support plate to move downwards. The support plate then drives the sleeve to slide downwards on the surface of the central column, and the sleeve compresses the spring. The sleeve drives the sliding rod to move through the movable shaft, and the sliding rod drives the clamping arm to rotate around the connecting shaft. The clamping arm drives the clamping blocks to rotate through the pin, so that the three sets of clamping blocks rotate towards the center position and contact the outer wall of the hazardous waste bin to center and clamp it, thereby preventing the hazardous waste bin from shaking and avoiding contact and collision between them. When it is necessary to move the hazardous waste bin... To remove the hazardous waste bin, simply move it upwards. The spring's elasticity causes the sleeve to move upwards, which in turn moves the clamping arm back to its original position via a sliding rod. The clamping arm then moves the clamping block away from the bin, allowing you to easily remove it. Alternatively, reverse the operation of the lifting motor and hydraulic cylinder. The lifting motor moves the hazardous waste bin into the explosion-proof container for storage. The explosion-proof cover closes on the container, providing protection for the hazardous waste. This convenient, centrally positioned clamping mechanism prevents the hazardous waste bin from shaking and improves the safety of hazardous waste storage. Attached Figure Description

[0025] Please see Figure 1-5 An embodiment of this utility model provides: a hazardous waste storage device with an explosion-proof structure, including an explosion-proof tank 1 and a hydraulic cylinder 2. The hydraulic cylinder 2 is movably installed on the outer wall of the explosion-proof tank 1, and the hydraulic cylinder 2 plays a power driving role. A push arm 10 is installed at the output end of the hydraulic cylinder 2. A linkage arm 7 is provided at the end of the push arm 10 away from the hydraulic cylinder 2. A hinge shaft 11 is provided on the side of the linkage arm 7 near the push arm 10, and the linkage arm 7 is movably connected to the push arm 10 through the hinge shaft 11. An explosion-proof cover 3 is installed on the side wall of the linkage arm 7. A linkage shaft 8 is provided at the end of the linkage arm 7 near the explosion-proof tank 1, and the linkage arm 7 is movably connected to the explosion-proof tank 1 through the linkage shaft 8. Four sets of integrated frames 4 with equal spacing are installed on the inner wall of the explosion-proof tank 1. A placement plate 5 is provided inside the explosion-proof tank 1.

[0026] This device is made of high-strength explosion-proof steel and has explosion-proof function. When it is necessary to store hazardous waste, the hydraulic cylinder 2 is opened, and the hydraulic cylinder 2 drives the push arm 10 to move. The push arm 10 drives the linkage arm 7 to rotate around the linkage shaft 8 through the hinge shaft 11. The linkage arm 7 drives the explosion-proof cover 3 to rotate, thereby opening the explosion-proof cover 3. Then, the lifting motor 13 is opened, and the lifting motor 13 drives the lead screw 12 to rotate. With the lead screw 12 and the threaded sleeve 14 connected, the lead screw 12 drives the placement plate 5 to move upward through the threaded sleeve 14. The placement plate 5 drives multiple sets of placement seats 6 to move upward, so that the placement seats 6 move to the position of the mouth of the explosion-proof container 1. This makes it convenient for workers to place the hazardous waste container on the support plate 15, avoids workers bending over to operate, and reduces the probability of worker injury. It realizes convenient linkage opening and closing of the explosion-proof cover, and facilitates the lifting of the placement plate to make it convenient for workers to place the hazardous waste container.

[0027] The integrated frame 4 has a lead screw 12 installed inside, and a lifting motor 13 is installed at the top of the integrated frame 4. The lifting motor 13 plays the role of power drive, and the output end of the lifting motor 13 is connected to the lead screw 12.

[0028] The surface of the lead screw 12 is fitted with a threaded sleeve 14, and the threaded sleeve 14 is threadedly connected to the lead screw 12. The threaded sleeve 14 is also connected to the placement plate 5. The top of the placement plate 5 is equipped with multiple sets of placement seats 6 at equal intervals, and a central column 19 is installed at the center of each placement seat 6.

[0029] Sleeves 16 are slidably mounted on the surface of the central column 19. Multiple sets of springs 20 with equal spacing are installed at the bottom of each sleeve 16, and the springs 20 are connected to the placement seat 6. Three sets of sliding rods 22 with equal spacing are provided on the side wall of each sleeve 16. A movable shaft 21 is provided at the end of each sliding rod 22 near the sleeve 16, and the sliding rod 22 is movably connected to the sleeve 16 through the movable shaft 21. A bearing plate 15 is installed at the top of each sleeve 16.

[0030] Three sets of clamping arms 9 are provided at equal intervals on the outer wall of the placement seat 6. A connecting shaft 23 is installed on the side wall of each clamping arm 9. The clamping arm 9 is movably connected to the placement seat 6 through the connecting shaft 23, and the clamping arm 9 is slidably connected to the slide rod 22.

[0031] Each clamping arm 9 has a clamping block 17 at its top end, and each clamping block 17 has a pin 18 installed on its side wall. The clamping block 17 is movably connected to the clamping arm 9 through the pin 18.

[0032] The hazardous waste bin is placed on the support plate 15. The hazardous waste bin moves the support plate 15 downwards, causing the support plate 15 to slide downwards on the surface of the central column 19. The sleeve 16 compresses the spring 20, and the sleeve 16 moves the sliding rod 22 via the movable shaft 21. The sliding rod 22 rotates the clamping arm 9 around the connecting shaft 23. The clamping arm 9 rotates the clamping blocks 17 via the pin 18, causing the three sets of clamping blocks 17 to rotate towards the center position and contact the outer wall of the hazardous waste bin for center positioning and clamping. This prevents the hazardous waste bin from shaking and avoids contact and collision between the bins. When it is necessary to dispose of hazardous waste... When removing the hazardous waste bin, simply move the bin upwards. Under the elastic action of spring 20, spring 20 drives sleeve 16 upwards. Sleeve 16 then drives clamping arm 9 to reset via slide rod 22. Clamping arm 9 then drives clamping block 17 away from the hazardous waste bin, after which the hazardous waste bin can be removed. Reverse operation of lifting motor 13 and hydraulic cylinder 2 causes lifting motor 13 to move the hazardous waste bin into the explosion-proof container 1 for storage. Explosion-proof cover 3 closes on explosion-proof container 1. Explosion-proof container 1 and explosion-proof cover 3 protect the hazardous waste, achieving convenient center positioning and clamping of the hazardous waste bin to prevent shaking and improving the safety of hazardous waste storage.

[0033] Working Principle: This device is made of high-strength explosion-proof steel and has explosion-proof function. When it is necessary to store hazardous waste, the hydraulic cylinder 2 drives the push arm 10 to move. The push arm 10 drives the linkage arm 7 to rotate around the linkage shaft 8 via the hinge shaft 11. The linkage arm 7 drives the explosion-proof cover 3 to rotate, thereby opening the explosion-proof cover 3. The lifting motor 13 drives the lead screw 12 to rotate. The lead screw 12 drives the placement plate 5 to move upward via the threaded sleeve 14. The placement plate 5 drives multiple sets of placement seats 6 to move upward, so that the placement seats 6 move to the position of the mouth of the explosion-proof container 1. This makes it convenient for workers to place the hazardous waste bins on the support plate 15, avoiding workers bending over to operate and reducing the probability of worker injury. After the hazardous waste bins are placed on the support plate 15, the hazardous waste bins drive the support plate 15 to move downward. The support plate 15 drives the sleeve 16 to slide downward on the surface of the central column 19 and the sleeve 16 compresses the spring 20. The sleeve 16 drives the sliding sleeve 20 through the movable shaft 21. The lever 22 moves, and the sliding rod 22 drives the clamping arm 9 to rotate around the connecting shaft 23. The clamping arm 9 drives the clamping block 17 to rotate through the pin 18, so that the three sets of clamping blocks 17 rotate towards the center position and contact the outer wall of the hazardous waste bin to center and clamp it, thereby preventing the hazardous waste bin from shaking and contacting each other. When it is necessary to remove the hazardous waste bin, simply move the hazardous waste bin upward. Under the elastic action of the spring 20, the spring 20 drives the sleeve 16 to move upward. The sleeve 16 drives the clamping arm 9 to reset through the sliding rod 22. The clamping arm 9 drives the clamping block 17 away from the hazardous waste bin, and then the hazardous waste bin can be picked up. The lifting motor 13 and hydraulic cylinder 2 are operated in reverse. The lifting motor 13 drives the hazardous waste bin to move into the explosion-proof tank 1 for storage. The explosion-proof cover 3 closes on the explosion-proof tank 1. The explosion-proof tank 1 and the explosion-proof cover 3 protect the hazardous waste. The above is the complete usage of the hazardous waste storage device with explosion-proof structure.
