[0002] Wet kitchen waste mainly includes waste generated in residents' daily life and food processing, catering services, unit catering and other activities, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, etc.; the existing treatment methods for wet kitchen waste include waste pretreatment and conversion treatment, and the waste pretreatment steps include crushing and pulping in sequence, wherein crushing aims to break the waste into particles, while breaking bags and crushing other debris, such as glass containers, chopsticks, and ceramic tableware; pulping is to mix and stir the crushed waste, water, and auxiliary materials to convert it into a slurry that is easy to further process or utilize, and the slurry can be converted into recyclable materials in the conversion treatment, and the conversion treatment can be microbial degradation conversion or black soldier fly larvae nibbling conversion.

[0003] The existing kitchen waste wet garbage pulping device includes a tank body, and a stirring shaft and a spiral blade are arranged at the axis center of the tank body. When pulping, the crushed garbage, water and auxiliary materials are put into the tank body, and the stirring shaft drives the spiral blade to rotate to stir the slurry, and the spiral blade is used to drive the slurry to move vertically in the tank body, thereby increasing the movement range of the slurry and improving the mixing uniformity; at the same time, the spiral blade also plays a role of shearing the slurry to a certain extent, making the slurry further refined.

[0004] However, due to the poor fluidity of the slurry, once the amount of slurry in the tank is large, it is difficult to drive the entire slurry to move and mix evenly by the spiral blades alone, that is, the mixing slurry effect is limited. Summary of the invention

[0005] Aiming at the problem that the existing pulping and mixing effect is poor, a kitchen waste wet garbage mixing pulping device and a kitchen waste wet garbage treatment system are provided.

[0006] The present application provides a kitchen waste wet garbage mixing pulping device, which is specifically implemented by the following technical solutions: A kitchen waste wet garbage mixed pulping device comprises a tank body, a motor, a planetary gear mechanism, a main shaft, three secondary shafts, a screen, a feed pipe, a water inlet pipe and an auxiliary material delivery mechanism, wherein the tank body is cylindrical, the feed pipe and the water inlet pipe are both connected to the upper part of the tank body, and the auxiliary material delivery mechanism is used to deliver the auxiliary material into the water inlet pipe; the upper end of the tank body is coaxially rotatably connected with a circular cover plate, the upper end of the main shaft is coaxially rotatably connected with the cover plate, the secondary shaft is parallel to the main shaft and the three secondary shafts are evenly arranged around the circumference of the main shaft, the upper end of the secondary shaft is rotatably connected with the cover plate, the outer side of the main shaft is sleeved with a first spiral sheet, and the outer side of the secondary shaft is A second spiral piece is fixedly mounted on the sleeve, and the rotation direction of the second spiral piece is consistent with that of the first spiral piece; the planetary gear mechanism includes a ring gear, a planet carrier, a central gear fixed to the upper end of the main shaft and a planetary gear fixed to the upper end of the secondary shaft, the ring gear is fixed to the upper end of the tank body, and the planetary gears are respectively meshed with the central gear and the ring gear, the planetary carrier has three second rotating sleeves, and the second rotating sleeves are mounted on the outer side of the upper end of the secondary shaft, and the motor is used to drive the main shaft to rotate forward or reversely; the screen is installed on the inner bottom of the tank body, the screen is lower than the main shaft and the secondary shaft, and the lower end of the tank body is provided with a discharge pipe and a switch valve.

[0007] Through the above technical solution, during pulping, the crushed garbage (with debris) enters the tank body through the feed pipe. During this period, the auxiliary material delivery mechanism delivers the auxiliary material into the water inlet pipe, which is mixed with the water in the water inlet pipe and then enters the tank body through the water inlet pipe; the motor drives the main shaft to rotate, and through the cooperation of the central gear and the planetary gear, as well as the cooperation of the planetary gear and the ring gear, the main shaft and the first spiral piece are driven to rotate around their own axes, and the secondary shaft and the second spiral piece are driven to rotate around their own axes, and at the same time, the secondary shaft and the second spiral piece are driven to revolve around the axis of the tank body. In this way, when the motor drives the main shaft to rotate in the forward direction, the first spiral piece rotating in the forward direction is used to drive the slurry to move up, and the second spiral piece rotating in the reverse direction is used to drive the slurry to move up. It is used to drive the slurry downward, so that the slurry near the axis of the tank body moves up to the upper part of the tank body and flows radially outward to the vicinity of the inner wall of the tank body, and the slurry near the inner wall of the tank body moves down to the bottom of the tank body and flows radially inward to the vicinity of the axis of the tank body, thereby realizing the positive circulation flow of the overall slurry in the tank body (when the motor drives the main shaft to rotate in the opposite direction, the slurry flows in a reverse circulation), which greatly improves the flow range and flow speed of the slurry. At the same time, in this process, the secondary shaft and the second spiral blade revolve around the axis of the tank body, which can not only stir and shear the slurry to further refine the slurry, but also drive the slurry within the circumferential range of the tank body to move axially, thereby improving the slurry flow range and mixing uniformity, and comprehensively improving the mixing and slurrying effect.

[0008] After pulping is completed, the switch valve is opened, and the pulp passes through the screen and is discharged from the discharge pipe. The screen is used to screen out the sundries mixed in the pulp, including broken glass containers, chopsticks, ceramic tableware, plastic bags, etc.

[0009] Optionally, the first spiral sheet and the second spiral sheet are both provided with notches, the main shaft and the secondary shaft are both fixed with shear blades located in the notches, and the shear blades of the main shaft and the secondary shaft are staggered along the axial direction of the tank body.

[0010] Through the above technical solution, by setting the shear blades with axial offset, since the shear blades of the main shaft and the shear blades of the secondary shaft rotate in opposite directions, shear forces in opposite directions can be applied to the slurry, and the shearing effect is better, so as to further refine the slurry.

[0011] Optionally, it also includes an externally fixed hydraulic cylinder, the tank body includes an upper tank and a lower tank which are separately arranged, the screen is arranged at the upper port of the lower tank, a sliding pipe is fixed at the bottom of the lower tank, the sliding pipe is slidably connected with the discharge pipe, the upper tank is externally fixed, the hydraulic cylinder is used to drive the lower tank to move vertically, a sealing ring is provided at the fitting position of the lower tank and the upper tank, and the lower tank and the upper tank are detachably connected by fasteners.

[0012] Through the above technical solution, when the screen is blocked by debris or there are too many debris, the fasteners can be released, and then the hydraulic cylinder drives the lower tank to move downward, so that the lower tank is separated from the upper tank to expose the screen. At this time, the debris on the screen can be picked up manually or washed away with a high-pressure water gun to clean the screen.

[0013] After cleaning, the hydraulic cylinder drives the lower tank to move upward, and the lower tank and the upper tank are attached and the sealing ring is clamped to ensure the sealing, and finally the lower tank and the upper tank are fixed with fasteners.

[0014] Secondly, the setting of the sliding pipe can ensure that the lower tank will not interfere with the fixed discharge pipe when it moves vertically.

[0015] Optionally, a step groove is provided on the inner wall of the upper port of the lower tank, a limit groove is provided on the groove wall of the step groove, a fence is coaxially fixed to the outer edge of the screen, the fence is higher than the screen, a limit block is fixed to the fence, the fence is located in the step groove, the limit block is located in the limit groove, and the fence is provided with a hook hole.

[0016] Through the above technical solution, when the screen is blocked by debris or there are too many debris, the screen is exposed. A rod with a hook can be used, and the hook of the rod can be passed through the hook hole on the enclosure. Then the rod can be pulled up to remove the screen from the lower tank, so that the screen can be transferred to other cleaning stations for deep cleaning.

[0017] Secondly, the enclosure can enclose the debris on the screen to prevent the debris from sliding off the screen during the transfer process.

[0018] Furthermore, the cooperation between the limiting block and the limiting groove can limit the circumferential position of the screen, that is, prevent the screen from rotating relative to the lower tank, so as to improve the position stability of the screen.

[0019] Optionally, it also includes a steam pipe, the tank body has an observation window, the main shaft has an axially extending main flow channel, the secondary shaft has an axially extending secondary flow channel, the upper end of the main shaft is provided with a rotating joint, the outlet end of the rotating joint is connected with the upper end of the main flow channel, and the inlet end of the rotating joint is connected with the steam pipe, the center of the planetary carrier has a first rotating sleeve, the first rotating sleeve is rotatably arranged on the upper end of the main shaft, the inner wall of the first rotating sleeve is provided with an annular first confluence chamber, the first confluence chamber is connected with the main flow channel through a first air hole opened by the main shaft, the planetary carrier has a branch flow channel, the inner wall of the second rotating sleeve is provided with an annular second confluence chamber, the second confluence chamber is connected with the secondary flow channel through a second air hole opened by the secondary shaft, and the two ends of the branch flow channel are respectively connected with the first confluence chamber and the second confluence chamber; the lower ports of the main flow channel and the secondary flow channel are fixed with filter screens, and the filter screens are attached to the upper surface of the screen.

[0020] Through the above technical solution, the pulping state is observed through the observation window. When the pulping is about to end, that is, when the whole pulp is in the pulping state, steam is introduced into the steam pipe, and the steam enters the main channel of the main shaft through the rotary joint. At the same time, the steam in the main channel passes through the first air hole, the first confluence cavity, the branch channel, the second confluence cavity and the second air hole in turn into the secondary channel of the secondary shaft, and the steam in the main channel and the secondary channel moves downward to the filter and the screen, that is, the steam can heat the filter and the screen, and with the revolution of the secondary shaft, the heating range of the screen is larger, and the heat of the screen is transferred to the grease on the debris of the screen, so that the grease attached to the debris is heated and dissolved into the slurry, so as to reduce the loss of organic matter discharged from the slurry. At the same time, with the circulation of the slurry and the heating of the main shaft and the secondary shaft by steam, the whole slurry in the tank is gradually heated, so that the grease attached to the first spiral sheet and the second spiral sheet is dissolved into the slurry, further reducing the loss of organic matter discharged from the slurry.

[0021] Secondly, by setting the annular first confluence chamber and the second confluence chamber, it is ensured that during the rotation of the main shaft and the secondary shaft, the first air hole and the second air hole can always be connected with the first confluence chamber and the second confluence chamber, so that the steam can be stably transported.

[0022] The cam is an upper and lower member formed in a manner that is coaxial with the tank body, the upper and lower members being respectively provided with a plurality of upper and lower sliding cylinders, the plurality of upper and lower sliding cylinders being respectively provided with a plurality of upper rotating blades and a plurality of lower sliding cylinders, the plurality of upper and lower sliding cylinders being respectively provided with the plurality of lower rotating blades and a plurality of lower sliding cylinders and the plurality of upper and lower sliding cylinders being respectively provided with the plurality of upper rotating blades and a plurality of lower sliding cylinders and the plurality of upper and lower sliding cylinders being respectively provided with the plurality of The mesh of the intercepting net is larger than the mesh of the screen, the lower rotating blades are radially arranged along the lower moving circle, the lower rotating blades are lower than the intercepting net, the inclination direction of the lower rotating blades is opposite to the inclination direction of the upper rotating blades, and the wide surface area of ​​the lower rotating blades is larger than the wide surface area of ​​the upper rotating blades; when the motor drives the main shaft to rotate forward, the first spiral piece rotating forward is used to drive the slurry to move upward, the second spiral piece rotating in the reverse direction is used to drive the slurry to move downward, and the second spiral piece revolves in the forward direction around the axis of the tank body to drive the upper intercepting member and the lower intercepting member to rotate forward, the upper intercepting member rotating forward moves upward relative to the slurry, and the lower intercepting member rotating forward moves downward relative to the slurry; when the motor drives the main shaft to rotate reversely, the first spiral piece rotating in the reverse direction is used to drive the slurry to move downward, the second spiral piece rotating in the forward direction is used to drive the slurry to move upward, and the second spiral piece revolves in the reverse direction around the axis of the tank body to drive the upper intercepting member and the lower intercepting member to rotate reversely, the upper intercepting member rotating in the reverse direction moves downward relative to the slurry, and the lower intercepting member rotating in the reverse direction moves upward relative to the slurry.

[0023] When there are too many debris in the slurry, such as tableware residues, glass fragments and broken bones, the debris will affect the fluidity of the slurry driven by the first spiral and the second spiral to a certain extent, and will also cause the slurry to adhere and accumulate, making it difficult to disperse and mix.

[0024] Through the above technical solution, when the tank is fed, the upper intercepting member and the lower intercepting member are both located at the bottom of the tank, that is, they are stacked on the screen. After the feeding is completed, the motor drives the main shaft to rotate in the positive direction, and the first spiral piece rotating in the positive direction is used to drive the slurry to move upward, and the second spiral piece rotating in the reverse direction is used to drive the slurry to move downward, and the second spiral piece revolves in the positive direction around the axis of the tank to drive the upper intercepting member and the lower intercepting member to rotate in the positive direction, and the upper rotary blade moves relative to the slurry, and the slurry provides a lifting force to the upper rotary blade rotating in the positive direction, so that the upper intercepting member rotating in the positive direction moves upward relative to the slurry, and the paddle blade provides a descending force to the lower rotary blade rotating in the positive direction. The force causes the positively rotating lower intercepting member to move downward relative to the slurry, and at this time the lower intercepting member is more closely attached to the screen, and the axial position of the lower intercepting member remains unchanged; in the process of the upper intercepting member rotating positively and moving axially upward, the slurry passes through the gap between adjacent upper rotary blades, and the intercepting rods of the upper rotary blades continuously intercept the large particles of debris mixed in the slurry, so as to drive the large particles of debris to gradually move upward to the liquid surface of the slurry along with the upper intercepting member, and because the slurry at the axis of the tank body is in an upward movement and the slurry liquid surface is in a radial outflow state, it is not easy for the debris at the slurry liquid surface to flow radially inward to the first spiral sheet.

[0025] Then the motor drives the main shaft to rotate in the opposite direction, and the first spiral piece rotating in the opposite direction is used to drive the slurry to move downward, and the second spiral piece rotating forward is used to drive the slurry to move upward, and the second spiral piece revolves in the opposite direction around the axis of the tank body to drive the upper intercepting member and the lower intercepting member to rotate in the opposite direction, and the slurry provides a descending force to the reversely rotating upper spiral blade, so that the reversely rotating upper intercepting member moves downward relative to the slurry, and the blade provides an ascending force to the reversely rotating lower spiral blade, so that the reversely rotating lower intercepting member moves upward relative to the slurry, that is, the upper intercepting member located at the slurry liquid surface moves downward, and the lower intercepting member located at the bottom of the slurry moves downward, the upper intercepting member and the lower intercepting member move toward each other and contact in the middle layer of the slurry, and due to the wide surface of the lower spiral blade of the lower intercepting member The area is large, the rising force of the lower intercepting member is greater than the descending force of the upper intercepting member, and the lower intercepting member will drive the upper intercepting member to continue to move upward, that is, the interception net will move from the bottom of the slurry to the slurry liquid surface. In this process, the interception net will continuously intercept the medium-sized particles in the slurry, and the interception hook will also hook and intercept part of the medium-sized particles. The medium-sized particles are brought to the slurry liquid surface by the interception net and the interception hook (at this time, the upper intercepting member and the lower intercepting member are both located at the slurry liquid surface); and because the slurry at the axis of the tank body is moving downward and the slurry liquid surface is in a radial inward flow state, some of the debris at the liquid surface of the blade will be gathered between the upper edge and the lower edge, that is, intercepted by the lower edge, thereby reducing the occurrence of debris re-flowing into the first spiral sheet.

[0026] Finally, the motor drives the main shaft to rotate in the positive direction, and the second spiral piece revolves in the positive direction around the axis of the tank body to drive the upper interceptor and the lower interceptor to rotate in the positive direction. Since the upper interceptor has reached the slurry liquid surface, it is difficult for the upper interceptor to continue to move up, that is, the upper interceptor remains at the slurry liquid surface, and at the same time, the upper interceptor also maintains the state of supporting debris on the slurry liquid surface. Secondly, since the slurry at the axis of the tank body is moving up and the slurry liquid surface is in a radial outflow state, it is not easy for the debris at the slurry liquid surface to flow radially inward to the first spiral piece. The blade provides a downward force to the positively rotating lower spiral blade, so that the positively rotating lower interceptor moves downward relative to the slurry. The interception net on the lower interceptor that moves downward continues to intercept the residual medium particles in the slurry. The residual medium particles are located on the bottom surface of the interception net until the lower interceptor moves down to the state of fitting the screen. At this time, the residual medium particles will be confined between the interception net and the screen.

[0027] In summary, by setting the upper intercepting member and the lower intercepting member, and controlling the forward and reverse rotation of the upper intercepting member and the lower intercepting member to change the vertical movement direction and the stop position of the upper intercepting member and the lower intercepting member, large particles and medium particles can be intercepted separately, and the debris can be confined to the slurry liquid surface and the bottom of the slurry respectively, so that the amount of debris within the slurry flow range is greatly reduced, thereby improving the fluidity and uniformity of the slurry.

[0028] Optionally, the intercepting hook has two hook parts and the two hook parts are in opposite directions.

[0029] Optionally, there is a vertical gap between the upper side of the lower rotating blade and the bottom surface of the interception net, and the size of the vertical gap is smaller than the mesh size of the interception net.

[0030] Through the above technical solution, the vertical gap facilitates the passage of slurry and can also block small particles of debris passing through the slurry, thereby improving the interception effect.

[0031] The present application provides a kitchen waste wet garbage treatment system, which is specifically implemented by the following technical solutions: A kitchen waste wet garbage treatment system comprises a crushing device, a kitchen waste wet garbage mixing and pulping device, a storage device, a feeding device and a biological treatment device in sequence. The slurry made by the kitchen waste wet garbage mixing and pulping device enters the storage device for storage, and the feeding device is used to feed the slurry in the storage device into the biological treatment device.

[0032] Optionally, the biological treatment device includes a frame and a processing tank body, and the feeding device includes a horizontal slide rail, a horizontal reciprocating drive assembly, a slide seat, a conveying pump, a feeding pipe and a feeding head. The horizontal slide rail is installed directly above the processing tank body, the slide seat is slidably connected to the horizontal slide rail, the feeding head is installed on one side of the slide seat, the discharge end of the feeding head is set downward, the two ends of the feeding pipe are respectively connected to the storage device and the feeding head, the conveying pump is used to move the slurry in the feeding pipe, and the horizontal reciprocating drive assembly is used to drive the slide seat to slide back and forth relative to the horizontal slide rail.

[0033] Through the above technical solution, when the horizontal reciprocating drive assembly drives the slide seat to slide back and forth relative to the horizontal slide rail, the feeding head continuously feeds the slurry in the feeding pipe into the processing tank body, so that the slurry is evenly distributed in the processing tank body, and then the slurry is processed and transformed by the organisms in the processing tank body, which can be black soldier fly larvae.

[0034] The beneficial effects of this application are: 1. By setting the first spiral piece, the second spiral piece and the planetary gear mechanism, when the motor drives the main shaft to rotate in the forward direction, the first spiral piece rotating in the forward direction is used to drive the slurry to move upward, and the second spiral piece rotating in the reverse direction is used to drive the slurry to move downward, so that the slurry near the axis of the tank body moves upward to the upper part of the tank body and flows radially outward to the vicinity of the inner wall of the tank body, and the slurry near the inner wall of the tank body moves downward to the bottom of the tank body and flows radially inward to the vicinity of the axis of the tank body, thereby realizing the positive circulation flow of the overall slurry in the tank body, greatly improving the flow range and flow speed of the slurry. At the same time, in this process, the secondary shaft and the second spiral piece revolve around the axis of the tank body, which can not only stir and shear the slurry to further refine the slurry, but also drive the slurry within the circumferential range of the tank body to move axially, thereby improving the slurry flow range and mixing uniformity, and comprehensively improving the mixing slurrying effect; 2. By setting up a steam pipe, a hollow main shaft and a secondary shaft, steam can heat the filter and screen, and with the revolution of the secondary shaft, the heating range of the screen is larger, and the heat of the screen is transferred to the grease on the debris on the screen, so that the grease attached to the debris is heated and dissolved into the slurry, thereby reducing the loss of organic matter discharged from the slurry. At the same time, with the circulation of the slurry and the heating of the main shaft and the secondary shaft by steam, the entire slurry in the tank is gradually heated, so that the grease attached to the first spiral sheet and the second spiral sheet is dissolved into the slurry, further reducing the loss of organic matter discharged from the slurry; 3. By setting the upper intercepting member and the lower intercepting member, and controlling the forward and reverse rotation of the upper intercepting member and the lower intercepting member, the vertical movement direction and the stop position of the upper intercepting member and the lower intercepting member can be changed to intercept large particles of debris and medium particles separately and intercept them in batches, and the debris can be restricted to the slurry liquid surface and the bottom of the slurry respectively, so that the amount of debris within the slurry flow range is greatly reduced, thereby improving the fluidity and uniformity of the slurry.

[0058] The screen 13 is arranged horizontally and installed on the inner bottom of the tank body 1 . The screen 13 is lower than the main shaft 2 and the secondary shaft 3 . A discharge pipe 14 and a switch valve are arranged at the lower end of the tank body 1 .

[0059] During pulping, the crushed material enters the tank body 1 through the feed pipe 15. During this period, the auxiliary material delivery mechanism 152 delivers the auxiliary material into the water inlet pipe 151, which is mixed with the water in the water inlet pipe 151 and then enters the tank body 1 through the water inlet pipe 151. It is ensured that the liquid level of the slurry is higher than the first spiral piece 21 and the second spiral piece 31. Then the motor 12 is started, and the motor 12 drives the main shaft 2 to rotate. Through the cooperation of the central gear 51 and the planetary gear 52, and the cooperation of the planetary gear 52 and the ring gear 53, the main shaft 2 and the first spiral piece 21 are driven to rotate around their own axes, and the secondary shaft 3 and the second spiral piece 31 are driven to rotate around their own axes, and at the same time, the secondary shaft 3 and the second spiral piece 31 are driven to revolve around the axis of the tank body 1. In this way, when the motor 12 drives the main shaft 2 to rotate in the positive direction, the first spiral piece 21 rotating in the positive direction is used to drive the slurry to move upward ( Figure 3 The arrow in the figure indicates the direction of movement of the slurry when the first spiral blade 21 rotates forwardly), and the second spiral blade 31 rotating in the opposite direction is used to drive the slurry to move downward, so that the slurry near the axis of the tank body 1 moves up to the upper part of the tank body 1 and flows radially outward to the vicinity of the inner wall of the tank body 1, and the slurry near the inner wall of the tank body 1 moves down to the bottom of the tank body 1 and flows radially inward to the vicinity of the axis of the tank body 1, thereby realizing the positive circulation flow of the entire slurry in the tank body 1 (when the motor 12 drives the main shaft 2 to rotate in the opposite direction, the slurry flows in the reverse circulation), which greatly improves the flow range and flow speed of the slurry. At the same time, in this process, the secondary shaft 3 and the second spiral blade 31 revolve around the axis of the tank body 1, which can not only stir and shear the slurry to further refine the slurry, but also drive the slurry within the circumferential range of the tank body 1 to move axially, thereby improving the slurry flow range and mixing uniformity, and comprehensively improving the mixing and slurrying effect.

[0060] After pulping is completed, the switch valve is opened, and the pulp passes through the screen 13 and is discharged from the discharge pipe 14. The screen 13 is used to screen out the sundries mixed in the pulp, including broken glass containers, chopsticks, ceramic tableware, plastic bags, etc.

[0061] like Figure 4 As shown, the biological treatment device 50 includes a frame 501 and a processing tank body 502. In other embodiments, the biological treatment device 50 can adopt the Chinese patent with announcement number CN221128524U, that is, multiple processing tank bodies 502 can be moved in a cycle, so that each processing tank body 502 moves in turn to the bottom of the feeding device 40.

[0062] The feeding device 40 includes a horizontal slide rail 401, a horizontal reciprocating drive assembly 402, a slide 403, a conveying pump, a feeding pipe 405 and a feeding head 404. The horizontal slide rail 401 is externally fixed, the slide 403 is slidably connected to the horizontal slide rail 401, the feeding head 404 is installed on one side of the slide 403, the discharge end of the feeding head 404 is set downward, the two ends of the feeding pipe 405 are respectively connected to the storage device 30 and the feeding head 404, the conveying pump is used to move the slurry in the feeding pipe 405 (not shown in the figure), the horizontal reciprocating drive assembly 402 is used to drive the slide 403 to slide back and forth relative to the horizontal slide rail 401, and the horizontal reciprocating drive assembly 402 can be a cylinder or a screw transmission drive mechanism.

[0063] When the horizontal reciprocating drive assembly 402 drives the slide 403 to slide back and forth relative to the horizontal slide rail 401, the feeding head 404 continuously feeds the slurry in the feeding pipe 405 into the processing tank 502, so that the slurry is evenly distributed in the processing tank 502, and then the slurry is processed and transformed by the organisms in the processing tank 502.

[0064] Example 2 The difference between Example 2 and Example 1 is that Figure 5 As shown, the first spiral sheet 21 and the second spiral sheet 31 are both provided with a notch (not shown in the figure), and the main shaft 2 and the secondary shaft 3 are both fixed with a shear blade 22 located in the notch, and the shear blade 22 is provided in a plurality and is arranged circumferentially, and one end of the shear blade 22 of the main shaft 2 extends into the notch of the second spiral sheet 31, and the shear blade 22 of the main shaft 2 and the shear blade 22 of the secondary shaft 3 are axially staggered along the tank body 1.

[0065] By setting the shear blade 22 axially offset, since the shear blade 22 of the main shaft 2 and the shear blade 22 of the secondary shaft 3 rotate in opposite directions, shear forces in opposite directions can be applied to the slurry, especially to the circulating slurry, and the shearing effect is better to further refine the slurry.

[0066] Example 3 The difference between Example 3 and Example 1 is that Figure 6 , Figure 7 As shown, the kitchen waste wet garbage mixing pulping device 20 also includes a hydraulic cylinder 17, and the tank body 1 includes an upper tank 101 and a lower tank 102 which are separately arranged. The upper tank 101 is fixedly arranged externally by a bracket (not shown in the figure), and the lower tank 102 and the upper tank 101 are detachably fixedly connected by fasteners 103. A sealing ring 104 is provided at the fitting position of the lower tank 102 and the upper tank 101 to ensure the sealing.

[0067] The fastener 103 may be a bolt, which is inserted and fixed to the flanges of the upper tank 101 and the lower tank 102 .

[0068] The cylinder body of the hydraulic cylinder 17 is fixed to the ground, the piston rod of the hydraulic cylinder 17 is arranged vertically, and the end of the piston rod of the hydraulic cylinder 17 is fixed to the lower tank 102, so that the hydraulic cylinder 17 can drive the lower tank 102 to move vertically. In addition, a slide pipe 105 is fixed to the bottom of the lower tank 102, the discharge pipe 14 is fixed to the storage device 30, and the slide pipe 105 is vertically penetrated and slidably connected with the discharge pipe 14. The arrangement of the slide pipe 105 can ensure that the lower tank 102 will not interfere with the fixed discharge pipe 14 when it moves vertically.

[0069] An annular step groove 1022 is provided on the inner wall of the upper port of the lower tank 102, and a limiting groove 1021 is provided on the groove wall of the step groove 1022. A fence 131 is coaxially fixed to the outer edge of the screen 13. The fence 131 is higher than the screen 13, and a limiting block 133 is fixed to the bottom of the fence 131. The fence 131 is located in the step groove 1022 to achieve the cooperation between the screen 13 and the lower tank 102, and the limiting block 133 is located in the limiting groove 1021, which can limit the screen 13 circumferentially, that is, prevent the screen 13 from rotating relative to the lower tank 102, so as to improve the position stability of the screen 13.

[0070] The enclosure 131 is provided with a hook hole 132 .

[0071] When the screen 13 is clogged with debris or there are too many debris, the fastener 103 can be released, and then the hydraulic cylinder 17 drives the lower tank 102 to move downward, so that the lower tank 102 is separated from the upper tank 101 to expose the screen 13. At this time, the debris on the screen 13 can be picked up manually or washed away with a high-pressure water gun to clean the screen 13.

[0072] Alternatively, a rod with a hook is used, the hook of the rod passes through the hooking hole 132 on the enclosure 131, and then the rod is pulled to remove the screen 13 from the lower tank 102, so that the screen 13 can be transferred to another cleaning station for deep cleaning. The enclosure 131 can enclose the debris on the screen 13 to prevent the debris from sliding off the screen 13 during the transfer process.

[0073] After cleaning, the hydraulic cylinder 17 drives the lower tank 102 to move upward, and the lower tank 102 and the upper tank 101 are attached and the sealing ring 104 is clamped to ensure the sealing, and finally the lower tank 102 and the upper tank 101 are fixed by the fastener 103.

[0074] Example 4 The difference between Example 4 and Example 1 is that Figure 8 , Fig. 9 , Fig.10 As shown, the kitchen waste wet garbage mixing pulping device 20 also includes a steam pipe 16, the tank body 1 has an observation window (not shown in the figure), the main shaft 2 has an axially extending main channel 23, the main channel 23 penetrates to the lower end of the main shaft 2, the secondary shaft 3 has an axially extending secondary channel 32, the secondary channel 32 penetrates to the lower end of the secondary shaft 3, the upper end of the main shaft 2 is sleeved with a rotary joint 161, the outlet end of the rotary joint 161 is connected to the upper end of the main channel 23, and the inlet end of the rotary joint 161 is connected to the steam pipe 16.

[0075] An annular first confluence cavity 544 is formed on the inner wall of the first rotating sleeve 541 . The first confluence cavity 544 is communicated with the main flow channel 23 through the first air hole 24 formed on the main shaft 2 .

[0076] The planet carrier 54 has a branch channel 543, and the inner wall of the second rotating sleeve 542 is provided with an annular second confluence chamber 545. The second confluence chamber 545 is connected to the secondary channel 32 through the second air hole 33 opened by the secondary shaft 3, and the two ends of the branch channel 543 are respectively connected to the first confluence chamber 544 and the second confluence chamber 545.

[0077] like Fig.11 As shown, the lower ends of the main flow channel 23 and the secondary flow channel 32 are both fixed with filter screens 25 , the mesh of the filter screen 25 is smaller than the mesh of the screen 13 , and the filter screen 25 is attached to the upper surface of the screen 13 .

[0078] The pulping state is observed through the observation window. When the pulping is about to end, that is, when the entire pulp is in a pulping state, steam is introduced into the steam pipe 16, and the steam enters the main flow channel 23 of the main shaft 2 through the rotary joint 161. At the same time, the steam in the main flow channel 23 passes through the first air hole 24, the first confluence cavity 544, the branch flow channel 543, the second confluence cavity 545 and the second air hole 33 in sequence and enters the secondary flow channel 32 of the secondary shaft 3 ( Figure 9-11 The direction of the arrow in the figure is the steam flow direction), and the steam in the main channel 23 and the secondary channel 32 moves downward to the filter 25 and the screen 13, that is, the steam can heat the filter 25 and the screen 13, and with the revolution of the secondary shaft 3, the steam has a larger heating range for the screen 13, and the heat of the screen 13 is transferred to the grease on the debris of the screen 13, so that the grease attached to the debris is heated and dissolved in the slurry, so as to reduce the loss of organic matter discharged from the slurry.

[0079] At the same time, as the slurry circulates and steam heats the main shaft 2 and the secondary shaft 3, the entire slurry in the tank body 1 is gradually heated, so that the grease attached to the first spiral blade 21 and the second spiral blade 31 is dissolved into the slurry, further reducing the loss of organic matter when discharging the slurry.

[0080] Secondly, by setting the annular first confluence chamber 544 and the second confluence chamber 545, it is ensured that during the rotation of the main shaft 2 and the secondary shaft 3, the first air hole 24 and the second air hole 33 can always be connected with the first confluence chamber 544 and the second confluence chamber 545, so that the steam can be stably transported.

[0081] Example 5 The difference between Example 5 and Example 3 is that Fig.12 , Fig.13 , Fig.14 As shown, the main shaft 2 is fixed with an annular upper edge 26 and an annular lower edge 27, the upper edge 26 is higher than the slurry liquid level, the lower edge 27 is lower than the slurry liquid level, and the diameters of the upper edge 26 and the lower edge 27 are greater than or equal to the diameter of the first spiral sheet 21, and the lower edge 27 is penetrated by densely arranged through holes 271, and the through holes 271 are vertically penetrated.

[0082] The kitchen waste wet garbage mixing pulping device 20 also includes an upper intercepting member 6 and a lower intercepting member 7 coaxially arranged with the tank body 1, the upper intercepting member 6 includes an upper moving ring 61, and the lower intercepting member 7 includes a lower moving ring 71, the upper moving ring 61 is located directly above the lower moving ring 71, and the upper moving ring 61 is fixed with multiple upper rotary blades 63 and three upper slides 62. Specifically, the upper slide 62 is fixed to the inner wall of the upper moving ring 61 by a support rod 64, the upper slide 62 is coaxially arranged with the secondary shaft 3, and the upper slide 62 is sleeved on the outer side of the second spiral sheet 31, so that the upper slide 62 can be axially slidably connected with the second spiral sheet 31. Therefore, when the secondary shaft 3 revolves, it will drive the upper slide 62 and the upper moving ring 61 to rotate around the axis of the tank body 1, that is, drive the upper intercepting member 6 to rotate.

[0083] The upper rotating blades 63 are arranged radially along the upper moving circle 61, and each upper rotating blade 63 is evenly arranged around the axis of the upper moving circle 61. One end of the upper rotating blade 63 away from the axis of the upper moving circle 61 is fixedly connected to the inner wall of the upper moving circle 61. A plurality of interception rods 65 arranged vertically upward are fixed to one long side of the upper rotating blade 63, and each interception rod 65 is arranged at equal intervals along the length direction of the upper rotating blade 63. A plurality of interception hooks 66 arranged downward are fixed to the other long side of the upper rotating blade 63, and each interception hook 66 is arranged at equal intervals along the length direction of the upper rotating blade 63, and the spacing between adjacent interception hooks 66 is smaller than the spacing between adjacent interception rods 65. The interception hook 66 has two hooks, and the directions of the two hooks are opposite.

[0084] The lower moving circle 71 is fixed with an intercepting net 72, a plurality of lower spiral blades 76 and three lower sliding cylinders 75. Specifically, the outer edge of the intercepting net 72 is fixed to the inner wall of the upper port of the lower moving circle 71. The mesh of the intercepting net 72 is larger than the mesh of the screen 13. The intercepting net 72 is penetrated by four through holes 73, one of which is adapted to the outer diameter of the first spiral sheet 21, and the inner walls of the other three through holes 73 are fixed to the lower sliding cylinder 75. The lower sliding cylinder 75 is arranged at the same time as the secondary shaft 3. The lower sliding cylinder 75 is sleeved on the outer side of the second spiral sheet 31, so that the lower sliding cylinder 75 can be axially slidably connected with the second spiral sheet 31. Therefore, when the secondary shaft 3 revolves, it will drive the lower sliding cylinder 75 and the lower moving circle 71 to rotate around the axis of the tank body 1, that is, drive the lower intercepting member 7 to rotate.

[0085] The lower rotating blades 76 are arranged radially along the lower moving circle 71, and the lower rotating blades 76 are evenly arranged around the circumference of the axis of the lower moving circle 71. The end of the lower rotating blade 76 away from the axis of the lower moving circle 71 is fixedly connected to the inner wall of the lower moving circle 71. The lower rotating blades 76 are lower than the intercepting net 72, and there is a vertical gap between the upper side of the lower rotating blades 76 and the bottom surface of the intercepting net 72, and the size of the vertical gap is smaller than the mesh size of the intercepting net 72.

[0086] The inclination direction of the lower rotating blade 76 is opposite to the inclination direction of the upper rotating blade 63 , and the wide surface area of ​​the lower rotating blade 76 is larger than the wide surface area of ​​the upper rotating blade 63 .

[0087] When there are too many debris in the slurry, such as tableware residues, glass fragments and broken bones, the debris will affect the fluidity of the slurry driven by the first spiral plate 21 and the second spiral plate 31 to a certain extent, and will also cause the slurry to adhere and accumulate and be difficult to disperse and mix.

[0088] Therefore, the above technical solution can be used to solve the problem. Specifically, when the tank body 1 is fed, the upper intercepting member 6 and the lower intercepting member 7 are both located at the bottom of the tank body 1, that is, the upper intercepting member 6 and the lower intercepting member 7 are both stacked on the screen 13. After the feeding is completed, the motor 12 drives the main shaft 2 to rotate forward, and the first spiral piece 21 rotating forward is used to drive the slurry to move upward, and the second spiral piece 31 rotating in the reverse direction is used to drive the slurry to move downward (refer to Fig.15 In the first state diagram in the figure, the directions of arrows in the figure are the slurry flow direction, the movement direction of the upper intercepting member 6 and the movement direction of the lower intercepting member 7 respectively), and the second spiral plate 31 revolves in the positive direction around the axis of the tank body 1 to drive the upper intercepting member 6 and the lower intercepting member 7 to rotate positively, and the upper rotary blade 63 moves relative to the slurry, and the slurry provides an upward force to the positively rotating upper rotary blade 63, so that the positively rotating upper intercepting member 6 moves upward relative to the slurry, and the blade provides a downward force to the positively rotating lower rotary blade 76, so that the positively rotating lower intercepting member 7 moves downward relative to the slurry, and at this time the lower intercepting member 7 is more closely attached to the screen 13, and the axial position of the lower intercepting member 7 remains unchanged.

[0089] During the process of the upper intercepting member 6 rotating forward and moving axially upward, the slurry passes through the gaps between the adjacent upper rotating blades 63, and the upper rotating blades 63 and the intercepting rods 65 continuously intercept the large particles of debris mixed in the slurry, so as to drive the large particles of debris to gradually move upward to the liquid surface of the slurry along with the upper intercepting member 6 (refer to Fig.15 ), and because the slurry at the axis of the tank body 1 is in an upward movement and the slurry liquid surface is in a radial outward flow state, it is difficult for the debris at the slurry liquid surface to flow radially inward to the first spiral sheet 21, that is, the occurrence of debris re-flowing into the first spiral sheet 21 is reduced.

[0090] Then the motor 12 drives the spindle 2 to rotate in the opposite direction (refer to Fig.15 In the third state diagram in the figure), the reverse rotating first spiral blade 21 is used to drive the slurry to move downward, and the forward rotating second spiral blade 31 is used to drive the slurry to move upward, and the second spiral blade 31 revolves in the opposite direction around the axis of the tank body 1 to drive the upper intercepting member 6 and the lower intercepting member 7 to rotate in the opposite direction, and the slurry provides a downward force to the reverse rotating upper rotary blade 63, so that the reverse rotating upper intercepting member 6 moves downward relative to the slurry (the large particles of debris originally on the upper intercepting member 6 are separated from the upper intercepting member 6 and remain in the state of the slurry liquid surface), and the blade provides an upward force to the reverse rotating lower rotary blade 76, so that the reverse rotating lower intercepting member 7 moves upward relative to the slurry, that is, the upper intercepting member 6 located at the slurry liquid surface moves downward, and the lower intercepting member 7 located at the bottom of the slurry moves downward, and the upper intercepting member 6 and the lower intercepting member 7 move toward each other and contact each other in the middle layer of the slurry (refer to Fig.16 As shown in the first state diagram in FIG. 1 , since the wide surface area of ​​the lower rotating blade 76 of the lower intercepting member 7 is larger, the upward force of the lower intercepting member 7 is greater than the downward force of the upper intercepting member 6, and the lower intercepting member 7 will drive the upper intercepting member 6 to continue to move upward, that is, the interception net 72 will move from the bottom of the slurry to the slurry liquid surface. In this process, the interception net 72 will continuously intercept the medium-sized particles in the slurry, and the interception hook 66 will also hook and intercept part of the medium-sized particles. The medium-sized particles are brought to the slurry liquid surface by the interception net 72 and the interception hook 66 (refer to FIG. 1 ). Fig.16 In the second state diagram in FIG, at this time, the upper intercepting member 6 and the lower intercepting member 7 are both located at the slurry liquid surface); and at this time, since the slurry at the axis of the tank body 1 is moving downward and the slurry liquid surface is in a radial inward flow state, some debris at the liquid surface of the impeller blades will be collected between the upper edge 26 and the lower edge 27, that is, intercepted by the lower edge 27, thereby reducing the occurrence of debris re-flowing into the first spiral sheet 21.

[0091] Finally, the motor 12 drives the spindle 2 to rotate in the positive direction (refer to Fig.16In the third state diagram in FIG), the second spiral piece 31 revolves in the positive direction around the axis of the tank body 1 to drive the upper interception member 6 and the lower interception member 7 to rotate in the positive direction. Since the upper interception member 6 has reached the slurry liquid surface, it is difficult for the upper interception member 6 to continue to move upward, that is, the upper interception member 6 remains at the slurry liquid surface, and at the same time, the upper interception member 6 also maintains the state of supporting debris on the slurry liquid surface. Secondly, since the slurry at the axis of the tank body 1 is in an upward movement and the slurry liquid surface is in a radial outflow state, it is not easy for the debris at the slurry liquid surface to flow radially inward to the first spiral piece 21. The blade provides a downward force to the positively rotating lower spiral blade 76, so that the positively rotating lower interception member 7 moves downward relative to the slurry. The interception net 72 on the lower interception member 7 that moves downward continues to intercept the residual medium particles in the slurry. The residual medium particles are located on the bottom surface of the interception net 72 until the lower interception member 7 moves down to the state of fitting the screen 13. At this time, the residual medium particles will be confined between the interception net 72 and the screen 13.

[0092] In summary, by setting the upper intercepting member 6 and the lower intercepting member 7, the forward and reverse rotations of the upper intercepting member 6 and the lower intercepting member 7 are controlled to change the vertical movement direction and the stop position of the upper intercepting member 6 and the upper intercepting member 6, so as to achieve the interception of large particles and medium particles respectively, and confine the debris to the slurry liquid surface and the bottom of the slurry respectively, so that the amount of debris within the flow range of the slurry is greatly reduced, thereby improving the fluidity and uniformity of the slurry.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
