Technical Field

[0003] At present, in the traditional hazardous waste treatment method, the hazardous waste is usually first filtered to form a dense filter cake for subsequent transportation or further treatment. Then, a pulper is used to break the filter cake into a slurry to facilitate subsequent filtration, separation and other processes.

[0004] However, in actual operation, the effect of single pulping of the filter cake is limited. After pulping, large pieces of material may not be completely broken up, which affects the final treatment effect.

[0008] By adopting the above technical scheme, the first conveying mechanism continuously and stably conveys the filter cake from the raw material bin to the pretreatment mechanism, ensuring the smooth progress of the entire process; the pretreatment mechanism cuts pre-dividing grooves on the bottom of the filter cake and breaks the filter cake along the pre-dividing grooves, which not only increases the contact area of ​​the filter cake, but also further increases the cross-sectional roughness of the filter cake because the filter cake is broken instead of cut, which helps to improve the efficiency and crushing quality of subsequent pulping, reduce large pieces of material, and reduce the difficulty of pulping; the second conveying mechanism promptly delivers the broken filter cake to the first pulping mechanism to ensure close connection between various processes; the first pulping mechanism performs preliminary Beating to generate primary slurry; the screening mechanism can effectively separate the slurry in the primary slurry from the incompletely broken blocks; the second beating mechanism is specifically used to perform secondary beating on the screened blocks to further improve the treatment effect, so that the originally solid hazardous waste filter cake can be effectively converted into a usable liquid form; the storage mechanism is used to collect the slurry screened by the screening mechanism and the secondary slurry generated after the secondary beating, which is convenient for subsequent storage or reprocessing; the beating device for hazardous waste treatment can achieve comprehensive and efficient beating treatment of the filter cake formed by the filter press of hazardous waste through pretreatment and secondary beating.

The breaking knife is arranged on the breaking platform, and the compacting and conveying assembly is arranged above the breaking platform. The compacting and conveying assembly can make the filter cake close to the breaking platform and drive the filter cake to move horizontally into the second conveying mechanism, so that the breaking knife can draw a pre-breaking groove at the bottom of the filter cake.

[0010] By adopting the above technical scheme, the cooperation between the breaking platform and the first conveying mechanism enables the filter cake to be smoothly conveyed from the raw material bin to the breaking platform; the pressing and conveying assembly can make the filter cake close to the breaking platform, and the breaking knife is arranged on the breaking platform, so that when the filter cake passes through, the filter cake can be subjected to the pressure from above, and a pre-breaking groove is cut at the bottom of the filter cake by the breaking knife, thereby pre-determining the breaking position of the filter cake, reducing the force required for breaking, and improving the efficiency and feasibility of subsequent breaking operations; at the same time, the breaking knife can also guide the filter cake so that the filter cake moves along the extension direction of the breaking knife; this design not only ensures the stability of the filter cake during movement, but also enables the breaking knife to accurately act on the bottom of the filter cake to form a uniform pre-breaking groove, laying a good foundation for subsequent breaking.

[0012] By adopting the above technical solution, the support frame provides support for the conveyor belt so that the conveyor belt can rotate; the pushing members arranged at intervals on the conveyor belt are used to make the filter cake located between the two pushing members, so that the filter cake can be pushed by the pushing members to drive the filter cake to move, so that the filter cake can fit tightly with the separating platform, thereby ensuring that the separating knife can reliably draw a pre-splitting groove at the bottom of the filter cake; the flexible member on the conveyor belt can provide pressing force to the filter cake on the one hand, and on the other hand, it can use the flexibility of the flexible member itself to reduce the risk of excessive force on the filter cake causing the residue to scatter on the separating platform and affect the cleanliness; the minimum vertical distance between the compacting conveying component and the separating platform is equal to or less than the thickness of the filter cake, so that the filter cake is always in a controlled state during the entire conveying process, thereby improving the accuracy and efficiency of the pretreatment; the setting of the compacting conveying component can keep the filter cake stable during the conveying process, prevent it from offsetting or falling during the movement, thereby improving the reliability of the filter cake pretreatment during the hazardous waste treatment process.

[0013] Optionally, the pretreatment mechanism also includes a cover shell, a breaking component and two groups of carrying components. The cover shell is arranged above the second conveying mechanism, the two groups of the carrying components are connected to the cover shell for carrying the filter cake, and the pre-breaking groove is arranged between the two groups of the carrying components.

[0016] By adopting the above technical solution, the horizontal rack moves in the direction away from the entrance of the cover shell under the push of the filter cake, thereby driving the first gear to rotate, and the first gear is connected to the second gear in transmission, thereby driving the vertical rack to move downward; the lower end of the vertical rack is connected with a downward pressure piece, and in the process of the vertical rack moving downward, the downward pressure piece can accurately act on the top of the pre-breaking groove on the filter cake, and realize the precise breaking of the filter cake by pushing the downward force; this design not only improves the efficiency of breaking the filter cake, but also ensures that the filter cake is evenly broken along the predetermined position, reduces the energy consumption and time cost in the subsequent processing process, and enables the filter cake to be effectively divided into smaller parts, thereby improving the effect and efficiency of subsequent pulping; the breaking component can be automatically triggered when the filter cake enters the cover shell, and the linkage mechanism of the horizontal rack and the vertical rack is used to realize the precise breaking of the filter cake, and after the filter cake is broken, it can be reset by the telescopic pusher to break the next filter cake.

[0018] By adopting the above technical solution, the first end of the pressing member away from the entrance of the cover shell is lower than the second end close to the entrance of the cover shell. This inclined design helps to gradually apply pressure when the filter cake enters, avoiding sudden impact that may cause uneven breakage of the filter cake and excessive resistance to the filter cake entering the cover shell; at the same time, the blade structure on the lower side of the first end of the pressing member can reduce the resistance to the filter cake after the filter cake reaches the position above the pre-breaking groove, and ensure that the filter cake can reliably enter the cover shell by partially cutting the filter cake; the arc structure on the lower side of the second end can disperse the pressure, and realize the breaking of the filter cake by the downward pressure, and increase the roughness of the cross section by breaking, thereby improving the quality and efficiency of subsequent pulping.

Finally, the rotation of the second gear will cause the vertical rack to move downward, so that the lower pressure piece applies force downward, breaks the filter cake along the pre-breaking groove, improves the breaking efficiency of the filter cake, and makes the filter cake break accurately along the predetermined position, thereby improving the overall beating effect and work efficiency.

[0021] Optionally, the bearing assembly includes a bearing rod, a first elastic member, a second elastic member, a slider and a pushing block, the sliders are provided at both ends of the bearing rod, the sliders are slidably connected to the cover shell, the first elastic member is correspondingly arranged to the slider, the two ends of the first elastic member are respectively connected to the slider and the cover shell, so that the bearing rod can move horizontally, the pushing block is slidably connected to the lower side of the horizontal rack, one end of the pushing block close to the entrance of the cover shell is connected to one end of the second elastic member, and the other end of the second elastic member is connected to the side wall of the horizontal rack so that the pushing block can be reset by the second elastic member, and the pushing block can extend between the two bearing rods, the telescopic pushing member is arranged in the cover shell, the telescopic end of the telescopic pushing member is connected to a long pushing part and a short pushing part, the short pushing part is used to push the horizontal rack to reset, and the long pushing part is used to push the pushing block to separate the two bearing rods.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 -Attached Figure 7 The present application is further described in detail. In this embodiment, if not clearly specified, "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, etc., which can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact not directly but through another feature between them. Moreover, in the description of the present embodiment, the terms "above", "below", "left", "right", etc., and the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. Unless otherwise specified, the orientation words used in the present application, such as "inside" and "outside", refer to the contours of the corresponding parts themselves.

[0038] like Figure 1 and Figure 2As shown, the embodiment of the present application discloses a pulping device for hazardous waste treatment (hereinafter referred to as "device"). The device includes a first conveying mechanism 1, a pretreatment mechanism 2, a second conveying mechanism 3, a first pulping mechanism 4, a screening mechanism 5, a second pulping mechanism 6 and a storage mechanism 7 with a cavity therein, and the device is used to fully pulp the filter cake formed by the filter pressing of hazardous waste.

[0039] The first conveying mechanism 1 is used to continuously and stably convey the filter cake from the raw material bin to the pretreatment mechanism 2 to ensure the smooth progress of the entire process. The first conveying mechanism 1 can be a conveyor belt structure. The pretreatment mechanism 2 is arranged at the output port of the first conveying mechanism 1. The pretreatment mechanism 2 is used to mark the bottom of the filter cake with a pre-splitting groove and break the filter cake along the pre-splitting groove. The pretreatment mechanism 2 not only increases the contact area of ​​the filter cake by marking the pre-splitting groove at the bottom of the filter cake and breaking the filter cake along the pre-splitting groove, but also further increases the cross-sectional roughness of the filter cake because the filter cake is broken rather than cut, which helps to improve the efficiency and crushing quality of subsequent pulping, reduce bulk materials, and reduce the difficulty of pulping. The input port of the second conveying mechanism 3 is arranged below the output port of the pretreatment mechanism 2, and is used to convey the broken filter cake, and the broken filter cake is promptly delivered to the first pulping mechanism 4 to ensure the close connection between each process.

[0040] like Figure 1 and Figure 2 As shown, the first beating mechanism 4 cooperates with the output port of the second conveying mechanism 3 to transport the broken filter cake to the first beating mechanism 4 through the second conveying mechanism 3. The first beating mechanism 4 is used to preliminarily beat the filter cake to form a primary slurry. The screening mechanism 5 is arranged at the output port of the first beating mechanism 4. The screening mechanism 5 is used to screen the primary slurry to separate the slurry in the primary slurry from the incompletely broken blocks. The screening mechanism 5 is provided with a first outlet 51 and a second outlet. The first outlet 51 outputs the blocks, and the second outlet outputs the slurry. The second beating mechanism 6 is arranged at the first outlet 51 of the screening mechanism 5. The second beating mechanism 6 is used to beat the blocks to form a secondary slurry. The storage mechanism 7 is connected to the second outlet and the output port of the second beating mechanism 6. The storage mechanism 7 is used to collect the slurry and the secondary slurry for subsequent storage or reprocessing. The device can realize comprehensive and efficient beating treatment of the filter cake formed by the filter press of hazardous waste through pretreatment and secondary beating, thereby improving the beating quality.

[0041] When in use, the first conveying mechanism 1 continuously conveys the filter cake from the raw material bin to the pretreatment mechanism 2. The pretreatment mechanism 2 first cuts a pre-dividing groove on the bottom of the filter cake, and breaks the filter cake into two halves along the pre-dividing groove. Then, the second conveying mechanism 3 conveys the two halves to the first beating mechanism 4, and the first beating mechanism 4 performs preliminary beating on them to form a primary slurry. Subsequently, the screening mechanism 5 screens the primary slurry to separate the slurry and block materials therein, and the slurry is discharged through the second outlet and enters the storage mechanism 7, while the block materials are sent to the second beating mechanism 6 through the first outlet 51 for further beating, and finally form a secondary slurry. The secondary slurry is also sent to the storage mechanism 7 to be mixed and stored with the previous primary slurry. This series of operations not only improves the beating efficiency, but also ensures the safety and environmental protection of the hazardous waste treatment process.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the pretreatment mechanism 2 includes a breaking platform 21, a breaking knife 22 and a pressing and conveying assembly 23. The first end of the breaking platform 21 cooperates with the output port of the first conveying mechanism 1, so that the filter cake can be moved from the first conveying mechanism 1 to the breaking platform 21. The breaking knife 22 is arranged on the breaking platform 21, and the breaking knife 22 extends along the conveying direction of the filter cake on the breaking platform 21. The pressing and conveying assembly 23 is arranged above the breaking platform 21, and the pressing and conveying assembly 23 can make the filter cake close to the breaking platform 21, and drive the filter cake to move horizontally to the second conveying mechanism 3, so that when the filter cake passes through, the filter cake can be under the action of the upper pressure, and the pre-breaking groove can be drawn at the bottom of the filter cake by the breaking knife 22, so as to predetermine the breaking position of the filter cake, and reduce the force required for breaking, thereby improving the efficiency and feasibility of the subsequent breaking operation. At the same time, the breaking knife 22 can also guide the filter cake so that the filter cake moves along the extension direction of the breaking knife 22. This design not only ensures the stability of the filter cake during movement, but also enables the breaking knife 22 to accurately act on the bottom of the filter cake to form a uniform pre-breaking groove, laying a good foundation for subsequent breaking.

[0043] Optionally, the end of the breaking knife 22 close to the outlet of the first conveying mechanism 1 is tilted, which can effectively guide the filter cake to move smoothly and reduce the risk of the filter cake generating large resistance due to sudden contact with the breaking knife 22. The height of the breaking knife 22 protruding from the breaking platform 21 is less than the thickness of the filter cake, so that the filter cake will not be completely cut when passing through the breaking knife 22.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the pretreatment mechanism 2 includes a telescopic member 27, which can be a cylinder. The telescopic member 27 is arranged on the side of the breaking platform 21 away from the second conveying mechanism 3, and the telescopic member 27 is used to push the filter cake so that the filter cake moves to the bottom of the compacting conveying assembly 23. The setting of the first telescopic member 27 enables the filter cake to be accurately moved to the bottom of the compacting conveying assembly 23, ensuring that the subsequent pre-breaking and breaking operations are carried out smoothly, thereby improving the working stability and reliability of the entire device. At the same time, this design reduces the need for manual intervention, reduces labor intensity, and improves the degree of automation.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the compacting conveying assembly 23 includes a support frame 231, a conveyor belt 232, a plurality of pushers 233 and a plurality of flexible members 234. The support frame 231 is arranged above the separation platform 21, and the conveyor belt 232 is rotatably connected to the support frame 231. The support frame 231 provides support for the conveyor belt 232 so that the conveyor belt 232 can be rotated. The support frame 231 includes a frame body, two transmission rollers and a driving motor. The frame body is connected to the separation platform 21, and the transmission roller is mounted on the frame body. The driving motor is connected to the transmission roller so that the transmission roller can rotate around its own axis. The conveyor belt 232 is tensioned and wound around two horizontally spaced transmission rollers to drive the conveyor belt 232 to rotate through the transmission rollers. A plurality of pushers 233 are spaced and distributed on the outer surface of the conveyor belt 232. The spacing between the two pushers 233 is greater than or equal to the diameter of the filter cake, so that the filter cake is located between the two pushers 233, so that the filter cake can be horizontally pushed by the pusher 233 to drive the filter cake to move. The filter cake can fit tightly with the separating platform 21, thereby ensuring that the separating knife 22 can reliably draw a pre-splitting groove at the bottom of the filter cake. The flexible member 234 is arranged between two hard pushing members 233. On the one hand, the flexible member 234 on the conveyor belt 232 can provide pressing force to the filter cake, and on the other hand, it can use the flexibility of the flexible member 234 itself to reduce the risk of excessive force on the filter cake causing the residue to scatter on the separating platform 21, affecting the neatness. The minimum vertical distance between the compacting conveying component 23 and the separating platform 21 is equal to or less than the thickness of the filter cake, so that the filter cake is always in a controlled state during the entire conveying process, thereby improving the accuracy and efficiency of the pretreatment. The setting of the compacting conveying component 23 can keep the filter cake stable during the conveying process, prevent it from deflecting or falling during the movement, thereby improving the reliability of the filter cake pretreatment during the hazardous waste treatment process.

[0046] Optionally, the flexible member 234 has the same height as the pushing member 233. The flexible member 234 has the same height as the pushing member 233, which ensures that the filter cake can be evenly stressed during the transmission process, avoids the filter cake breakage or jamming caused by height differences, and improves the stability and reliability of the equipment operation. At the same time, when the flexible member 234 is squeezed, the pushing member 233 can achieve a pushing effect on the filter cake, thereby improving the overall processing effect. The flexible member 234 can be made of a flexible material such as rubber or sponge.

[0047] like Figure 3 , Figure 4 and Figure 5 As shown, optionally, the pretreatment mechanism 2 also includes a cover shell 24, a breaking assembly 25 and two groups of bearing assemblies 26. The cover shell 24 is arranged above the second conveying mechanism 3, and the cover shell 24 is used to provide support for the breaking assembly 25 and the bearing assembly 26. The two groups of bearing assemblies 26 are both slidably connected to the cover shell 24, and are used to carry and set up the filter cake. The pre-breaking groove is arranged between the two groups of bearing assemblies 26 and is suspended in the air, so that the filter cake can be broken along the pre-breaking groove by the breaking assembly 25, which is beneficial to the subsequent pulping process. The breaking assembly 25 is arranged in the cover shell 24, and is used to break the filter cake so that the broken filter cake falls into the input port of the second conveying mechanism 3.

[0048] Optionally, the breaking assembly 25 includes a horizontal rack 251, a first gear 252, a second gear 253, a vertical rack 254, a pressing member 255 and a telescopic pusher 265. The side wall of the horizontal rack 251 is slidably connected to the housing 24, and the horizontal rack 251 is slidably arranged on the bearing assembly 26. The first end of the horizontal rack 251 faces the entrance of the housing 24, and when the filter cake enters the housing 24, it can push the first end of the horizontal rack 251 to move away from the entrance of the housing 24. The vertical rack 254 is slidably connected to the housing 24, and the vertical rack 254 is tightly connected to the housing 24 and has a certain friction force, so that the vertical rack 254 will not move vertically without being driven by the second gear 253. The lower end of the vertical rack 254 is connected to the pressing piece 255, the first gear 252 is meshed with the horizontal rack 251, the second gear 253 is meshed with the vertical rack 254, and the first gear 252 is connected to the second gear 253 in transmission, so that when the filter cake pushes the horizontal rack 251 to move, it can drive the vertical rack 254 to move downward, and the pressing piece 255 presses down the upper part of the pre-splitting groove in the middle of the filter cake. Under the support of the two groups of bearing components 26, the two ends of the filter cake are upturned, so that the filter cake is broken along the pre-splitting groove. A moving belt 28 can be set at the end of the breaking platform 21 away from the first conveying mechanism 1, so that the filter cake can be reliably pushed into the cover 24; the moving belt 28 can be a conveyor belt structure. The horizontal rack 251 faces the side, which can reduce the impact of dust; the cover 24 can reduce the flying of dust.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, the pushing member 233 and the moving belt 28 can provide sufficient driving force for the filter cake, so that the horizontal rack 251 moves in the direction away from the entrance of the cover shell 24 under the push of the filter cake, thereby driving the first gear 252 to rotate, and the first gear 252 is connected to the second gear 253 in transmission, thereby driving the vertical rack 254 to move downward; the lower end of the vertical rack 254 is connected to a pressing member 255, and in the process of the vertical rack 254 moving downward, the pressing member 255 can accurately act on the pre-breaking groove on the filter cake, and realize the precise breaking of the filter cake through the downward pressure; this design not only improves the efficiency of breaking the filter cake, but also ensures that the filter cake is evenly broken along the predetermined position, reduces the energy consumption and time cost in the subsequent processing process, and enables the filter cake to be effectively divided into two halves, thereby improving the effect and efficiency of subsequent pulping. The breaking assembly 25 can be automatically triggered when the filter cake enters the cover shell 24, and the linkage mechanism of the horizontal rack 251 and the vertical rack 254 is used to achieve accurate breaking of the filter cake. After the filter cake is broken, the telescopic pusher 265 can push the horizontal rack 251 to reset it so as to break the next filter cake.

[0050] like Figure 3 , Figure 4 and Figure 5 As shown, optionally, the breaking assembly 25 includes a transmission group 256, and the transmission group 256 includes a first connecting shaft 2561, a first sprocket 2562, a chain 2563, a second sprocket 2564, a second connecting shaft 2565, a first bevel gear 2566, a second bevel gear 2567 and a third connecting shaft 2568. The first connecting shaft 2561, the second connecting shaft 2565 and the third connecting shaft 2568 are all rotatably connected to the cover shell 24, the first connecting shaft 2561 is respectively connected to the first gear 252 and the first sprocket 2562, the chain 2563 is transmission-connected to the first sprocket 2562 and the second sprocket 2564, the second connecting shaft 2565 is respectively connected to the second sprocket 2564 and the first bevel gear 2566, the first bevel gear 2566 and the second bevel gear 2567 are meshed, and the third connecting shaft 2568 is respectively connected to the second bevel gear 2567 and the second gear 253, so that the horizontal rack 251 moves away from the entrance of the cover shell 24, which can drive the vertical rack 254 to move downward.

[0051] When the filter cake enters the housing 24, it can push the horizontal rack 251 to move, thereby driving the first gear 252 to rotate. The first gear 252 drives the first sprocket 2562 to rotate through the first connecting shaft 2561, thereby driving the second sprocket 2564 through the first sprocket 2562 and the chain 2563. The second sprocket 2564 then drives the first bevel gear 2566 on the second connecting shaft 2565 to rotate, and the first bevel gear 2566 meshes with the second bevel gear 2567, thereby driving the second gear 253 on the third connecting shaft 2568 to rotate. Finally, the rotation of the second gear 253 will cause the vertical rack 254 to move downward, so that the lower pressure piece 255 applies force downward, breaks the filter cake along the pre-breaking groove, improves the breaking efficiency of the filter cake, and makes the filter cake break accurately along the predetermined position, thereby improving the overall beating effect and work efficiency.

[0052] like Figure 3 , Figure 4 and Figure 5 As shown, optionally, the first end of the pressing member 255 away from the entrance of the housing 24 is lower than the second end of the pressing member 255 close to the entrance of the housing 24. This inclined design helps to gradually apply pressure when the filter cake enters, avoiding uneven damage to the filter cake caused by sudden impact and excessive resistance to the filter cake entering the housing 24. The thickness of the lower side of the first end of the pressing member 255 is less than the thickness of the lower side of the second end of the pressing member 255. The lower side of the first end of the pressing member 255 is a blade structure, and the lower side of the second end of the pressing member 255 is an arc structure, which can reduce the resistance to the filter cake after the filter cake reaches the position above the pre-breaking groove, and ensure that the filter cake can reliably enter the housing 24 by partially cutting the filter cake. When the filter cake enters the housing 24, it can first contact the first end of the pressing member 255. Since the first end is designed to be lower than the second end, and the lower side of the first end is a blade structure, it can cut into the filter cake during the advancement of the filter cake, reducing the resistance to the horizontal movement of the filter cake. The arc-shaped structure on the lower side of the second end can disperse the pressure and break the filter cake by the downward pressure. The roughness of the cross section is increased by breaking, thereby improving the quality and efficiency of subsequent pulping and also improving the safety of use.

[0053] like Figure 3 , Figure 4 and Figure 5As shown, optionally, the bearing assembly 26 includes a bearing rod 261, a first elastic member 262, a second elastic member, a slider 263 and a push block 264. Slide blocks 263 are provided at both ends of the bearing rod 261, and the sliders 263 are slidably connected to the cover 24. The first elastic member 262 and the sliders 263 are arranged in a one-to-one correspondence, and the two ends of the first elastic member 262 are respectively connected to the sliders 263 and the cover 24, so that the bearing rod 261 can move horizontally. The push block 264 is slidably connected to the lower side of the horizontal rack 251, and the push block 264 can extend between the two bearing rods 261 to separate the two bearing rods 261. One end of the push block 264 close to the entrance of the cover 24 is connected to one end of the second elastic member, and the other end of the second elastic member is connected to the side wall of the horizontal rack 251, so that the push block 264 can be reset by the second elastic member. The telescopic pusher 265 is provided on the housing 24, and the telescopic end of the telescopic pusher 265 is connected to the long pusher 2651 and the short pusher 2652, the short pusher 2652 is used to push the horizontal rack 251 to reset, and the long pusher 2651 is used to push the pusher block 264. The bearing rod 261 is flush with the bottom of the inlet of the housing 24 to improve the stability of the filter cake.

[0054] like Figure 3 , Figure 5 and Figure 6 As shown, the combined design of the bearing rod 261, the slider 263 and the first elastic member 262 enables the bearing rod 261 to move flexibly in the horizontal direction to adjust the horizontal spacing between the two bearing rods 261. When the filter cake is broken and the horizontal rack 251 needs to be reset, the telescopic end of the telescopic pusher 265 extends out, and the long pusher 2651 first abuts against the push block 264 to push the push block 264, which can push the push block 264 into between the two bearing rods 261, compress the second elastic member, separate the two bearing rods 261, and ensure that the broken filter cake falls reliably into the second conveying mechanism 3; then the short pusher 2652 abuts against the horizontal rack 251 to push the horizontal rack 251 to reset, thereby improving the efficiency of filter cake pretreatment, reducing the need for manual intervention, and improving the automation of the entire hazardous waste treatment process. Subsequently, the telescopic end of the telescopic pusher 265 retracts, and the push block 264 is reset under the action of the second elastic member, so that the two bearing rods 261 are close to each other, so as to reliably carry the next filter cake.

[0055] like Figure 3 , Figure 4 and Figure 5As shown, the first elastic member 262 and the second elastic member can both be springs; the telescopic pusher 265 and the telescopic member 27 can both be structures that can achieve telescopic movement, such as a cylinder, a hydraulic cylinder or an electric telescopic rod. The pusher block 264 is provided with a protruding block, and a sliding groove is provided at the bottom of the horizontal rack 251. The protruding block is slidably connected to the sliding groove. The end of the protruding block away from the telescopic pusher 265 is provided with a second elastic member, and the second elastic member is provided at the end of the sliding groove away from the telescopic pusher 265, which is used to enable the pusher block 264 to automatically reset. The telescopic pusher 265 can be completely retracted into the side wall of the housing 24, and the pusher block 264 and the horizontal rack 251 are both selectively abutted against the telescopic end of the telescopic pusher 265. The front end of the pusher block 264 has an arc, and the width is less than the minimum horizontal distance between the two bearing rods 261, so as to extend between the two bearing rods 261 and adjust the distance between the two bearing rods 261.

[0056] The second conveying mechanism 3 can be a shaftless screw conveying structure, such as a screw conveyor, whose input port faces upward to receive the filter cake in the cover shell 24 and whose output port faces downward to convey the filter cake to the first beating mechanism 4 .

[0057] like Figure 2 and Figure 7 As shown, optionally, the first beating mechanism 4 includes a feed hopper 41, a first beating barrel 42, a first driving member 43, a first stirring shaft 44 and two groups of first stirring blades 45. The feed hopper 41 is eccentrically arranged, and the bottom of the feed hopper 41 is connected to the top of the first beating barrel 42, which can reduce the difficulty of feeding. The first beating barrel 42 is hexagonal, which helps to increase the irregular flow of materials during stirring and improve the beating effect. The first driving member 43 is arranged at the top of the first beating barrel 42, and the upper end of the first stirring shaft 44 is connected to the output end of the first driving member 43 to ensure the stability and reliability of power transmission. Two groups of first stirring blades 45 are vertically spaced and distributed on the first stirring shaft 44. The first stirring blades 45 are tilted, so that the material is subjected to multi-directional shear force and mixing during the beating process, effectively preventing the material from agglomerating and improving the quality of the primary slurry. The inclination directions of the two groups of first stirring blades 45 are opposite, forming a two-way stirring effect, enhancing the mixing effect, and making the primary slurry more delicate and uniform. The first stirring blade 45 can be a three-leaf type, and its rotation speed can be adjusted. A baffle plate may be provided in the first beating barrel 42 to increase the contact area with the filter cake and optimize the initial beating effect.

[0058] like Figure 2 and Figure 7As shown, the screening mechanism 5 can be a microfilter, so that the rotation speed and inclination angle of the rotating screen of the microfilter can be adjusted; in order to improve the screening effect, the mesh of the rotating screen is denser, for example, the mesh can be 60 mesh, and it is equipped with a water backwashing function, so that the blockage of the rotating screen can enter the second beating barrel 61 through the first outlet 51. In view of the existing structure of the screw conveyor and the microfilter, its specific structure and implementation principle will not be described in detail here. A transfer pump can also be provided between the first beating barrel 42 and the screening mechanism 5, which is used to transport the primary slurry in the first beating barrel 42 to the screening mechanism 5. A screen is set at the output port of the first beating barrel 42 to output the primary slurry by overflow, thereby reducing the risk of clogging the transfer pump.

[0059] Optionally, the second beating mechanism 6 includes a second beating barrel 61, a second driving member 62, a second stirring shaft 63 and a second stirring blade 64. The second driving member 62 is arranged at the top of the second beating barrel 61, the upper end of the second stirring shaft 63 is connected to the output end of the second driving member 62, and the second stirring blade 64 is arranged on the second stirring shaft 63, and the second stirring blade 64 is a plurality of knife-rake structures. The second beating mechanism 6 can further beating the block material output by the screening mechanism 5, so that the block material is broken into fine particles, thereby improving the quality and uniformity of the final slurry. The knife-rake type second stirring blade 64 design increases the contact area with the material, effectively improves the beating efficiency, reduces energy consumption, and improves the beating efficiency, so that the quality of the final slurry is more stable and reliable.

[0060] like Figure 2 and Figure 7As shown, when the block material enters the second beating barrel 61, the second driving member 62 starts and drives the second stirring shaft 63 to rotate. The second stirring blade 64 is designed as a knife rake type. Its rake-like structure can generate strong shearing force and impact force during high-speed rotation, thereby effectively crushing and refining the block material and converting it into fine and uniform secondary slurry. This design not only improves the beating efficiency, but also ensures that the quality of the final slurry is more stable and reliable. The first driving member 43 and the second driving member 62 can both be motors, and the output port of the second beating barrel 61 can also be provided with a screen. It can be understood that the screens in this embodiment are all detachably connected for easy replacement. The output port of the second beating barrel 61 is arranged at the upper part and outputs by overflow; a slag discharge port is provided at the bottom of the second beating barrel 61 for maintenance and slag discharge, and during maintenance, a lifting platform can be provided at the bottom of the second beating barrel 61 to lift the second beating barrel 61, so as to facilitate maintenance. The first beating barrel 42 and the second beating barrel 61 have similar structures, both of which include a barrel body and a barrel cover. The barrel covers of the first beating barrel 42 and the second beating barrel 61 are welded to the barrel body to improve the stability of the first driving member 43 and the second driving member 62, and at the same time improve the sealing performance. The bottom of the first beating barrel 42 and the second beating barrel 61 can be provided with a bottom valve to facilitate slag discharge and maintenance; the bottom of the storage mechanism 7 can also be provided with a bottom valve to transport the slurry to the next process.

[0061] It can be understood that the device also includes necessary structures for connection, support, driving, positioning, limiting, sealing and control functions so that the device can operate normally; the parameters such as the shape, size, material and setting quantity of each part of the device can be determined as needed as long as the corresponding functions can be achieved; two first beating barrels 42 can be set, and the two are interconnected to optimize the initial beating effect, and the hexagonal structure can facilitate stable cooperation between the two; liquid can be added to the first beating barrel 42 and the second beating barrel 61 as needed to facilitate the slurrying of the filter cake.

[0062] The implementation principle of a pulping device for hazardous waste treatment in an embodiment of the present application is as follows: a first conveying mechanism 1 continuously and stably conveys the filter cake from a raw material bin to a pretreatment mechanism 2, which not only increases the contact surface area of ​​the filter cake by marking a pre-dividing groove on the bottom of the filter cake and breaking the filter cake along the pre-dividing groove, but also further increases the cross-sectional roughness of the filter cake because the filter cake is broken by breaking rather than cutting, making the filter cake easy to be broken, which helps to improve the efficiency and crushing quality of subsequent pulping, reduce large pieces of material, and reduce the difficulty of pulping; the second conveying mechanism 3 promptly delivers the broken filter cake to the first pulping mechanism 4, the first pulping mechanism 4 performs preliminary pulping on the filter cake to generate a primary pulp, the screening mechanism 5 separates the pulp in the primary pulp from the blocks that are not completely broken, and the second pulping mechanism 6 performs secondary pulping specifically on the screened blocks to further improve the treatment effect; the storage mechanism 7 collects the pulp screened by the screening mechanism 5 and the secondary pulp generated after the secondary pulping, which is convenient for subsequent storage or reprocessing. The beating device for hazardous waste treatment can achieve comprehensive and efficient beating treatment of the filter cake formed by the pressure filtration of hazardous waste through pretreatment and secondary beating, so that the particle size index and concentration of the slurried material are more stable and more controllable. The step-by-step beating can also reduce the problem of long time caused by the difficulty of breaking the block materials in the slurry, reduce long-term noise, and optimize the working environment. At the same time, rapid crushing can also reduce wear on the device and reduce the need for maintenance of the device.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
