Description

Technical Field

[0001] This application belongs to the technical field of kitchen waste treatment, and relates to a kitchen wet waste mixing pulping device and a kitchen wet waste treatment system. Background Art

[0002] Kitchen wet waste mainly includes the waste generated in residents' daily life, food processing, food service, unit meal supply and other activities, including discarded vegetable leaves, leftovers, rice, fruit peels, etc.; the existing treatment methods for kitchen wet waste include garbage pretreatment and conversion treatment. The garbage pretreatment steps include crushing and pulping in sequence. The crushing aims to break the garbage into particles, and at the same time break the bags and crush other sundries, such as glass containers, chopsticks, ceramic tableware. Pulping is to mix and stir the crushed garbage, water, and auxiliary materials to convert them into a slurry that is easy to further process or utilize. This slurry can be converted into recycled materials in the conversion treatment. The conversion treatment can be microbial degradation conversion or black soldier fly larva predation conversion.

[0003] The existing kitchen wet waste pulping device includes a tank body, and a stirring shaft and a spiral blade are arranged at the axis of the tank body. During pulping, the crushed garbage, water, and auxiliary materials are put into the tank body. The stirring shaft drives the spiral blade to rotate to stir the slurry, and the spiral blade drives the slurry to move vertically in the tank body to increase the moving range of the slurry, thereby improving the mixing uniformity; at the same time, the spiral blade also plays a role in 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 body is large, it is difficult for the spiral blade alone to drive the movement and uniform mixing of the whole slurry, that is, the mixing pulping effect is limited. Summary of the Invention

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

[0006] This application provides a kitchen wet waste mixing pulping device, and specifically adopts the following technical solutions to achieve:

[0007] A wet kitchen waste mixing pulping device, comprising a tank body, a motor, a planetary gear mechanism, a main shaft, three auxiliary shafts, a screen, a feed pipe, a water inlet pipe and an auxiliary material feeding mechanism. The tank body is in a cylindrical shape. The feed pipe and the water inlet pipe are both connected to the upper part of the tank body. The auxiliary material feeding mechanism is used to feed auxiliary materials into the water inlet pipe. A circular cover plate is coaxially and rotatably connected to the upper end of the tank body. The upper end of the main shaft is coaxially and rotatably connected to the cover plate. The auxiliary shafts are parallel to the main shaft and the three auxiliary shafts are evenly arranged around the circumference of the main shaft. The upper ends of the auxiliary shafts are rotatably connected to the cover plate. A first spiral blade is sleeved and fixed outside the main shaft. A second spiral blade is sleeved and fixed outside the auxiliary shaft. The second spiral blade has the same helix direction as the first spiral blade. The planetary gear mechanism includes a gear ring, a planetary carrier, a central gear fixed to the upper end of the main shaft and a planetary gear fixed to the upper end of the auxiliary shaft. The gear ring is fixed to the upper end of the tank body. The planetary gears are respectively meshed with the central gear and the gear ring. The planetary carrier has three second rotating sleeves which are sleeved outside the upper ends of the auxiliary shafts. The motor is used to drive the main shaft to rotate forward or backward. The screen is installed at the inner bottom of the tank body. The screen is lower than the main shaft and the auxiliary shafts. A discharge pipe and a switching valve are arranged at the lower end of the tank body.

[0008] Through the above technical solution, during pulping, the crushed garbage (carrying sundries) enters the tank body through the feed pipe. During this period, the auxiliary material feeding mechanism feeds the auxiliary materials into the water inlet pipe, and they are mixed with the water in the water inlet pipe and then enter the tank body through the water inlet pipe. The motor drives the main shaft to rotate. Through the cooperation of the central gear and the planetary gears, and the cooperation of the planetary gears and the gear ring, the main shaft and the first spiral blade are driven to rotate around their own axes, the auxiliary shafts and the second spiral blades are driven to rotate around their own axes, and at the same time, the auxiliary shafts and the second spiral blades are driven to revolve around the axis of the tank body. In this way, when the motor drives the main shaft to rotate forward, the forward rotating first spiral blade is used to drive the pulp to move upward, and the reverse rotating second spiral blade is used to drive the pulp to move downward, so that the pulp near the axis of the tank body moves upward to the upper part of the tank body and flows radially outward to near the inner wall of the tank body, and the pulp near the inner wall of the tank body moves downward to the bottom of the tank body and flows radially inward to near the axis of the tank body, thereby realizing the positive circulation flow of the overall pulp in the tank body (when the motor drives the main shaft to rotate reversely, the pulp flows in reverse circulation). This greatly improves the flow range and flow speed of the pulp. At the same time, during this process, the auxiliary shafts and the second spiral blades revolve around the axis of the tank body, which can not only stir and shear the pulp to further refine the pulp, but also drive the pulp in the circumferential range of the tank body to move axially, thereby improving the flow range and mixing uniformity of the pulp and comprehensively improving the mixing pulping effect.

[0009] After pulping is completed, the switching 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. The sundries include broken glass containers, chopsticks, ceramic tableware, plastic bags, etc.

[0010] Optionally, notches are formed in both the first helical blade and the second helical blade. Shearing blades located within the notches are fixed to both the main shaft and the auxiliary shaft, and the shearing blades of the main shaft and the shearing blades of the auxiliary shaft are arranged axially staggered along the axis of the tank body.

[0011] Through the above technical solution, by providing shearing blades arranged axially staggered, since the shearing blades of the main shaft and the shearing blades of the auxiliary shaft rotate in opposite directions, opposite shearing forces can be applied to the slurry, and the shearing effect is better to further refine the slurry.

[0012] Optionally, it further includes a hydraulically cylinder fixedly arranged externally. 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 to the bottom of the lower tank, and the sliding pipe is slidably connected through the discharge pipe in a penetrating manner. The upper tank is fixedly arranged externally. The hydraulically cylinder is used to drive the lower tank to move vertically. A sealing ring is arranged at the fitting position between the lower tank and the upper tank, and the lower tank and the upper tank are detachably connected through fasteners.

[0013] Through the above technical solution, when the screen is blocked by sundries or there are too many sundries, the fasteners can be removed, and then the hydraulically 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 sundries on the screen can be picked up manually or washed away by a high-pressure water gun to clean the screen.

[0014] After the cleaning is completed, the hydraulically cylinder drives the lower tank to move upward. The lower tank and the upper tank are fitted together and the sealing ring is clamped to ensure the sealing performance. Finally, the lower tank and the upper tank are fixed by fasteners.

[0015] Secondly, the arrangement of the sliding pipe can ensure that the vertical movement of the lower tank will not interfere with the fixedly arranged discharge pipe.

[0016] Optionally, a stepped groove is formed in the inner wall of the upper port of the lower tank. A limiting groove is arranged on the groove wall of the stepped groove. A retaining wall is coaxially fixed to the outer edge of the screen. The retaining wall is higher than the screen. A limiting block is fixed to the retaining wall. The retaining wall is located within the stepped groove, and the limiting block is located within the limiting groove. A hooking hole is formed in the retaining wall.

[0017] Through the above technical solution, when the screen is blocked by sundries or there are too many sundries and the screen is exposed, a rod with a hook can be used. The hook of the rod passes through the hooking hole on the retaining wall, and then the rod is lifted to remove the screen from the lower tank to transfer the screen to other cleaning stations for in-depth cleaning.

[0018] Secondly, the retaining wall can enclose the sundries on the screen to prevent the sundries from slipping off the screen during the transfer process.

[0019] Moreover, the cooperation between the limiting block and the limiting groove can circumferentially limit the screen, that is, prevent the screen from rotating relative to the lower tank, so as to improve the position stability of the screen.

[0020] Optionally, it further includes a steam pipe. The tank body has an observation window. The main shaft has a main flow channel extending axially, and the auxiliary shaft has an auxiliary flow channel extending axially. A rotary joint is provided at the upper end of the main shaft. The outlet end of the rotary joint is communicated with the upper end of the main flow channel, and the inlet end of the rotary joint is communicated with the steam pipe. A first rotating sleeve is provided at the center of the planetary carrier. The first rotating sleeve is rotatably sleeved on the upper end of the main shaft. An annular first confluence chamber is provided on the inner wall of the first rotating sleeve. The first confluence chamber is communicated with the main flow channel through a first air hole opened on the main shaft. The planetary carrier has a branch flow channel. An annular second confluence chamber is provided on the inner wall of the second rotating sleeve. The second confluence chamber is communicated with the auxiliary flow channel through a second air hole opened on the auxiliary shaft. Both ends of the branch flow channel are communicated with the first confluence chamber and the second confluence chamber respectively; filter nets are fixed at the lower ports of the main flow channel and the auxiliary flow channel, and the filter nets are attached to the upper surface of the screen.

[0021] 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 overall pulp is in a pulped state, steam is introduced through the steam pipe. The steam enters the main flow channel of the main shaft through the rotary joint. At the same time, the steam in the main flow channel sequentially enters the auxiliary flow channel of the auxiliary shaft through the first air hole, the first confluence chamber, the branch flow channel, the second confluence chamber and the second air hole. The steam in the main flow channel and the auxiliary flow channel moves downward to the filter net and the screen, that is, the steam can heat the filter net and the screen. And as the auxiliary shaft revolves, the heating range of the screen is relatively large. The heat of the screen is transferred to the grease on the sundries on the screen, so that the grease attached to the sundries is heated and dissolved into the pulp, so as to reduce the loss of organic matter in the discharged pulp. At the same time, as the pulp circulates and the steam heats the main shaft and the auxiliary shaft, the overall pulp in the tank is gradually heated, so that the grease attached to the first spiral blade and the second spiral blade is dissolved into the pulp, further reducing the loss of organic matter in the discharged pulp.

[0022] Secondly, by providing the annular first confluence chamber and the second confluence chamber, it is ensured that during the rotation of the main shaft and the auxiliary shaft, the first air hole and the second air hole can always be communicated with the first confluence chamber and the second confluence chamber, so that the steam is stably transported.

[0023] Optionally, it further includes an upper interceptor and a lower interceptor coaxially arranged with the tank body. The upper interceptor includes an upper moving ring, and the lower interceptor includes a lower moving ring. The liquid level of the slurry is higher than the first helical blade and the second helical blade. The main shaft is fixed with an annular upper edge and an annular lower edge. The upper edge is higher than the liquid level of the slurry, and the lower edge is lower than the liquid level of the slurry. The lower edge is provided with densely arranged through holes; the upper moving ring is directly above the lower moving ring. The upper moving ring is fixed with a plurality of upper helical blades and three upper sliding cylinders. The upper sliding cylinders are sleeved on the outside of the second helical blade, and the upper sliding cylinders are axially slidably connected to the second helical blade. The upper helical blades are arranged radially along the upper moving ring. One long side of the upper helical blade is fixed with a plurality of vertically upwardly arranged intercepting rods, and the other long side of the upper helical blade is fixed with a plurality of downwardly arranged intercepting hooks. The distance between adjacent intercepting hooks is smaller than the distance between adjacent intercepting rods; the lower moving ring is fixed with an intercepting net, a plurality of lower helical blades and three lower sliding cylinders. The lower sliding cylinders are sleeved on the outside of the second helical blade, and the lower sliding cylinders are axially slidably connected to the second helical blade. The mesh of the intercepting net is larger than the mesh of the sieve net. The lower helical blades are arranged radially along the lower moving ring. The lower helical blades are lower than the intercepting net. The inclination direction of the lower helical blades is opposite to the inclination direction of the upper helical blades. The wide surface area of the lower helical blades is larger than the wide surface area of the upper helical blades; when the motor drives the main shaft to rotate forward, the forward-rotating first helical blade is used to drive the slurry to move upward, and the reverse-rotating second helical blade is used to drive the slurry to move downward. And the second helical blade revolves forward around the axis of the tank body to drive the upper interceptor and the lower interceptor to rotate forward. The forward-rotating upper interceptor moves upward relative to the slurry, and the forward-rotating lower interceptor moves downward relative to the slurry; when the motor drives the main shaft to rotate in the reverse direction, the reverse-rotating first helical blade is used to drive the slurry to move downward, and the forward-rotating second helical blade is used to drive the slurry to move upward. And the second helical blade revolves in the reverse direction around the axis of the tank body to drive the upper interceptor and the lower interceptor to rotate in the reverse direction. The reverse-rotating upper interceptor moves downward relative to the slurry, and the reverse-rotating lower interceptor moves upward relative to the slurry.

[0024] When there are too many impurities in the slurry, such as tableware residues, glass fragments, and broken bones, etc., the impurities will affect the fluidity of the slurry driven by the first helical blade and the second helical blade to a certain extent. At the same time, it will also cause the slurry to adhere and accumulate and be difficult to disperse and mix.

[0025] Through the above technical solution, when feeding the tank body, both the upper interceptor and the lower interceptor are located at the bottom of the tank body, that is, stacked on the screen. After the feeding is completed, the motor drives the main shaft to rotate forward. The first helical blade rotating forward is used to drive the slurry to move upward, and the second helical blade rotating reversely is used to drive the slurry to move downward. Moreover, the second helical blade revolves forward around the axis of the tank body to drive the upper interceptor and the lower interceptor to rotate forward. The upper rotating blade moves relative to the slurry, and the slurry provides an upward force to the upper rotating blade rotating forward, causing the upper interceptor rotating forward to move upward relative to the slurry. While the slurry blade provides a downward force to the lower rotating blade rotating forward, causing the lower interceptor rotating forward to move downward relative to the slurry. At this time, the lower interceptor is more closely attached to the screen, and the axial position of the lower interceptor remains unchanged. During the process of the upper interceptor rotating forward and moving upward axially, the slurry passes through the gaps between adjacent upper rotating blades, and the intercepting rods of the upper rotating blades continuously intercept large particle impurities mixed in the slurry, driving the large particle impurities to gradually move upward with the upper interceptor to the liquid surface of the slurry. And because the slurry at the axis of the tank body is moving upward and the slurry liquid surface is in a state of flowing radially outward, the impurities at the slurry liquid surface are not easily radially inward flowed to the first helical blade.

[0026] Then the motor drives the main shaft to rotate reversely. The first helical blade rotating reversely is used to drive the slurry to move downward, and the second helical blade rotating forward is used to drive the slurry to move upward. Moreover, the second helical blade revolves reversely around the axis of the tank body to drive the upper interceptor and the lower interceptor to rotate reversely. The slurry provides a downward force to the upper rotating blade rotating reversely, causing the upper interceptor rotating reversely to move downward relative to the slurry. While the slurry blade provides an upward force to the lower rotating blade rotating reversely, causing the lower interceptor rotating reversely to move upward relative to the slurry. That is, the upper interceptor located at the slurry liquid surface moves downward, and the lower interceptor located at the bottom of the slurry moves downward. The upper interceptor and the lower interceptor move towards each other and contact at the middle position of the slurry. Due to the larger wide surface area of the lower rotating blade of the lower interceptor, the upward force of the lower interceptor is greater than the downward force of the upper interceptor, and the lower interceptor will drive the upper interceptor to continue to move upward, that is, the intercepting net will move upward from the bottom of the slurry to the slurry liquid surface. During this process, the intercepting net will continuously intercept medium particle impurities in the slurry, and the intercepting hook will also hook and intercept some medium particle impurities. The medium particle impurities are brought to the slurry liquid surface by the intercepting net and the intercepting hook (at this time, both the upper interceptor and the lower interceptor are 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 state of radially inward flowing, some impurities at the slurry liquid surface will be gathered between the upper edge and the lower edge, that is, intercepted by the lower edge, thus reducing the occurrence of impurities flowing back into the first helical blade.

[0027] Finally, the motor drives the main shaft to rotate forward, and the second spiral blade revolves around the axis of the tank body in the forward direction to drive the upper interceptor and the lower interceptor to rotate forward. Since the upper interceptor has reached the slurry liquid level, it is difficult for the upper interceptor to continue moving upward, that is, the upper interceptor stays at the slurry liquid level, and at the same time, the upper interceptor also holds the sundries at the slurry liquid level. Secondly, since the slurry at the axis of the tank body is moving upward and the slurry liquid level is flowing radially outward, the sundries at the slurry liquid level are not easily radially inwardly flowed to the first spiral blade. The paddle provides a downward force to the downward rotating blade that rotates forward, so that the downward interceptor that rotates forward moves downward relative to the slurry. For the downward interceptor that moves downward, the interception net thereon continuously intercepts the residual medium particles in the slurry, and the residual medium particles are located on the bottom surface of the interception net until the downward interceptor moves downward to fit the screen state. At this time, the residual medium particles will be restricted between the interception net and the screen.

[0028] In summary, by setting the upper interceptor and the lower interceptor, and using the forward and reverse rotations of the upper interceptor and the lower interceptor to control, the vertical movement directions and staying positions of the upper interceptor and the upper interceptor are changed to intercept large-particle sundries and medium particles respectively, and the sundries are respectively restricted at the slurry liquid level and the bottom of the slurry, so that the number of sundries in the slurry flow range is greatly reduced, thereby improving the fluidity and uniformity of the slurry.

[0029] Optionally, the hook part of the interception hook has two, and the directions of the two hook parts are opposite.

[0030] Optionally, there is a vertical gap between the upper side of the downward 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.

[0031] Through the above technical solution, the vertical gap facilitates the passage of the slurry, and at the same time can catch the small-particle sundries in the passed slurry, thereby improving the interception effect.

[0032] The present application provides a kitchen waste wet garbage treatment system, and specifically adopts the following technical solutions to achieve:

[0033] A kitchen waste wet garbage treatment system sequentially includes a crushing device, a kitchen waste wet garbage mixing and pulping device, a storage device, a feeding device and a biological treatment device. 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 put the slurry in the storage device into the biological treatment device.

[0034] Optionally, the biological treatment device includes a frame and a treatment tank body. The feeding device includes a horizontal slide rail, a horizontal reciprocating drive assembly, a sliding seat, a delivery pump, a feeding pipe, and a feeding head. The horizontal slide rail is installed directly above the treatment tank body. The sliding seat is slidably connected to the horizontal slide rail. The feeding head is installed on one side of the sliding seat. The discharge end of the feeding head is arranged downward. The two ends of the feeding pipe are respectively connected to the storage device and the feeding head. The delivery pump is used to move the slurry in the feeding pipe. The horizontal reciprocating drive assembly is used to drive the sliding seat to reciprocate relative to the horizontal slide rail.

[0035] Through the above technical solution, during the process that the horizontal reciprocating drive assembly drives the sliding seat to reciprocate relative to the horizontal slide rail, the feeding head continuously discharges the slurry in the feeding pipe into the treatment tank body, so that the slurry is evenly distributed in the treatment tank body. Then, the slurry is processed and transformed by the organisms in the treatment tank body. The organism can be black soldier fly larvae.

[0036] The beneficial effects of this application are as follows:

[0037] 1. By setting the first spiral blade, the second spiral blade, and the planetary gear mechanism, when the motor drives the main shaft to rotate forward, the forward-rotating first spiral blade is used to drive the slurry to move upward, and the reversely-rotating second spiral blade 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. 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, during this process, the auxiliary 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 increasing the flow range and mixing uniformity of the slurry, and comprehensively improving the mixing and pulping effect;

[0038] 2. By setting the steam pipe, the hollow main shaft, and the auxiliary shaft, the steam can heat the filter screen and the sieve mesh. And as the auxiliary shaft revolves, the heating range of the sieve mesh is relatively large. The heat of the sieve mesh is transferred to the grease on the sundries of the sieve mesh, so that the grease attached to the sundries is heated and dissolved into the slurry to reduce the loss of organic matter in the discharged slurry. At the same time, with the circulating flow of the slurry and the heating of the main shaft and the auxiliary shaft by the steam, the overall slurry in the tank body is gradually heated, so that the grease attached to the first spiral blade and the second spiral blade is dissolved into the slurry, further reducing the loss of organic matter in the discharged slurry;

[0039] 3. By setting up an upper interceptor and a lower interceptor, and controlling the forward and reverse rotation of the upper interceptor and the lower interceptor, the vertical movement direction and the stopping position of the upper interceptor and the lower interceptor are changed, so as to achieve the separate interception and batch interception of large particle debris and medium particles, and the debris is respectively restricted to the slurry liquid level and the bottom of the slurry, greatly reducing the number of debris within the slurry flow range, thereby improving the fluidity and uniformity of the slurry.

As Figure 1 shown, the kitchen waste wet garbage treatment system includes a crushing device 10, a kitchen waste wet garbage mixing and pulping device 20, a storage device 30, a feeding device 40, and a biological treatment device 50 that are connected in sequence. The crushing device 10 is used to crush the kitchen waste wet garbage and also break hard impurities and plastic bags in the garbage to make crushed materials. The crushed materials, water, and auxiliary materials are put into the kitchen waste wet garbage mixing and pulping device 20 to be mixed and stirred into a slurry for easier further treatment or utilization. The slurry made by the kitchen waste wet garbage mixing and pulping device 20 enters the storage device 30 for storage. The feeding device 40 is used to put the slurry in the storage device 30 into the biological treatment device 50. The biological treatment device 50 is used to process and convert the slurry into reusable substances. The biological conversion treatment can be microbial degradation conversion or black soldier fly larva cannibalism conversion. In this embodiment, black soldier fly larva cannibalism conversion is adopted.

[0061] As Figure 2 、 Figure 3 shown, the kitchen waste wet garbage mixing and pulping device 20 includes a tank body 1, a motor 12, a planetary gear mechanism, a main shaft 2, three auxiliary shafts 3, a screen 13, a feed pipe 15, a water inlet pipe 151, and an auxiliary material feeding mechanism 152. The tank body 1 is cylindrical. The feed pipe 15 and the water inlet pipe 151 are both connected to the upper part of the tank body 1. The feed pipe 15 is used to discharge the crushed materials into the tank body 1. The auxiliary material feeding mechanism 152 is used to put the auxiliary materials into the water inlet pipe 151. The auxiliary material feeding mechanism 152 can adopt an existing powder automatic metering feeder to pre-mix the auxiliary materials with water and then enter the tank body 1 through the water inlet pipe 151 to be mixed with the crushed materials.

[0062] The main shaft 2 and the auxiliary shafts 3 are both parallel to the axis of the tank body 1, and the main shaft 2 is coaxially arranged with the tank body 1. The upper end of the tank body 1 is coaxially and rotatably connected with a circular cover plate 11. The upper end of the main shaft 2 is coaxially and rotatably connected with the cover plate 11. The three auxiliary shafts 3 are evenly arranged around the circumference of the main shaft 2. The upper ends of the auxiliary shafts 3 are rotatably connected with the cover plate 11. A first spiral blade 21 is sleeved and fixed outside the main shaft 2, and a second spiral blade 31 is sleeved and fixed outside the auxiliary shaft 3. The spiral direction of the second spiral blade 31 is the same as that of the first spiral blade 21.

[0063] The planetary gear mechanism includes a ring gear 53, a planet carrier 54, a central gear 51 fixed to the upper end of the main shaft 2, and a planetary gear 52 fixed to the upper end of the auxiliary shaft 3. The ring gear 53 is fixed to the upper end of the tank body 1, and the ring gear 53 is coaxially arranged with the tank body 1. The teeth of the ring gear 53 face inward. The diameter of the planetary gear 52 is smaller than that of the central gear 51. The planetary gear 52 meshes with the central gear 51 and the ring gear 53 respectively. The planet carrier 54 has a first rotating sleeve 541 and three second rotating sleeves 542. The first rotating sleeve 541 is rotatably sleeved on the outer side of the upper end of the main shaft 2, and the second rotating sleeves 542 are rotatably sleeved on the outer side of the upper end of the auxiliary shaft 3. The motor 12 is externally fixed, and the motor 12 is located directly above the tank body 1. The output shaft of the motor 12 is fixedly connected to the upper end of the main shaft 2 through a coupling. The motor 12 is used to drive the main shaft 2 to rotate forward or backward.

[0064] The screen 13 is horizontally arranged and installed at the inner bottom of the tank body 1. The screen 13 is lower than the main shaft 2 and the auxiliary shaft 3. A discharge pipe 14 and a switch valve are provided at the lower end of the tank body 1.

[0065] During pulping, the crushed material enters the tank body 1 through the feed pipe 15. During this period, the auxiliary material feeding mechanism 152 feeds the auxiliary material into the water inlet pipe 151, mixes it with the water in the water inlet pipe 151, and then enters the tank body 1 through the water inlet pipe 151, and ensures that the liquid level of the pulp is higher than the first spiral blade 21 and the second spiral blade 31. Then the motor 12 is started. 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 blade 21 are driven to rotate around their own axes, and the auxiliary shaft 3 and the second spiral blade 31 are driven to rotate around their own axes, and at the same time the auxiliary shaft 3 and the second spiral blade 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 forward, the forward-rotating first spiral blade 21 is used to drive the pulp to move upward ( Figure 3 the arrow in is the moving direction of the pulp when the first spiral blade 21 rotates forward), and the reversely rotating second spiral blade 31 is used to drive the pulp to move downward, so that the pulp near the axis of the tank body 1 moves upward to the upper part of the tank body 1 and flows radially outward to near the inner wall of the tank body 1, and the pulp near the inner wall of the tank body 1 moves downward to the bottom of the tank body 1 and flows radially inward to near the axis of the tank body 1, so as to realize the positive circulation flow of the overall pulp in the tank body 1 (when the motor 12 drives the main shaft 2 to rotate reversely, the pulp flows in reverse circulation), greatly improving the flow range and flow speed of the pulp. At the same time, in this process, the auxiliary 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 pulp to further refine the pulp, but also drive the pulp in the circumferential range of the tank body 1 to move axially, thereby improving the flow range and mixing uniformity of the pulp and comprehensively improving the mixing pulping effect.

[0066] After the pulping is completed, the on-off 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, and the sundries include broken glass containers, chopsticks, ceramic tableware, plastic bags, etc.

[0067] As Figure 4 shown, the biological treatment device 50 includes a frame 501 and a treatment tank body 502. In other embodiments, the biological treatment device 50 can adopt the Chinese patent with the publication number CN221128524U, that is, multiple treatment tank bodies 502 can move cyclically, so that each treatment tank body 502 moves to directly below the feeding device 40 in turn.

[0068] The feeding device 40 includes a horizontal slide rail 401, a horizontal reciprocating drive assembly 402, a sliding seat 403, a delivery pump, a feeding pipe 405 and a feeding head 404. The horizontal slide rail 401 is externally fixed, the sliding seat 403 is slidably connected to the horizontal slide rail 401, the feeding head 404 is installed on one side of the sliding seat 403, the discharge end of the feeding head 404 is arranged downward, both ends of the feeding pipe 405 are respectively connected to the storage device 30 and the feeding head 404, the delivery pump is used to move the pulp in the feeding pipe 405 (not shown in the figure), and the horizontal reciprocating drive assembly 402 is used to drive the sliding seat 403 to reciprocate relative to the horizontal slide rail 401. The horizontal reciprocating drive assembly 402 can be a cylinder or a screw drive mechanism.

[0069] During the process that the horizontal reciprocating drive assembly 402 drives the sliding seat 403 to reciprocate relative to the horizontal slide rail 401, the feeding head 404 continuously feeds the pulp in the feeding pipe 405 into the treatment tank body 502, so that the pulp is evenly distributed in the treatment tank body 502, and then the pulp is processed and transformed by the organisms in the treatment tank body 502.

[0070] Embodiment 2

[0071] The difference between Embodiment 2 and Embodiment 1 is that, as Figure 5 shown, both the first spiral blade 21 and the second spiral blade 31 are provided with notches (not shown in the figure), and shear blades 22 located in the notches are fixed on both the main shaft 2 and the auxiliary shaft 3. The shear blades 22 are provided in multiple numbers and are arranged circumferentially. One end of the shear blade 22 of the main shaft 2 extends into the notch of the second spiral blade 31, and moreover, the shear blades 22 of the main shaft 2 and the shear blades 22 of the auxiliary shaft 3 are axially offset along the axis of the tank body 1.

[0072] By providing the shear blades 22 with axial offset, since the rotation directions of the shear blades 22 of the main shaft 2 and the shear blades 22 of the auxiliary shaft 3 are opposite, a shear force in the opposite direction can be applied to the pulp, especially for shearing the circulating pulp, and the shearing effect is better to further refine the pulp.

[0073] Embodiment 3

[0074] The difference between Example 3 and Example 1 is that, as Figure 6 , Figure 7 shown, the kitchen waste wet garbage mixing pulping device 20 further includes a hydraulic cylinder 17. The tank body 1 includes an upper tank 101 and a lower tank 102 which are separately arranged. The upper tank 101 is externally fixed through a bracket (not shown in the figure). The lower tank 102 and the upper tank 101 are detachably and fixedly connected through a fastener 103. A sealing ring 104 is arranged at the fitting position of the lower tank 102 and the upper tank 101 to ensure the sealing performance.

[0075] The fastener 103 can be a bolt, and the bolt passes through and fixes the flange plates of the upper tank 101 and the lower tank 102.

[0076] The cylinder body of the hydraulic cylinder 17 is fixed to the ground. The piston rod of the hydraulic cylinder 17 is arranged vertically. The end of the piston rod of the hydraulic cylinder 17 is fixed to the lower tank 102. The hydraulic cylinder 17 can drive the lower tank 102 to move vertically. And, a sliding pipe 105 is fixed to the bottom of the lower tank 102. The discharge pipe 14 is fixed to the storage device 30. The sliding pipe 105 and the discharge pipe 14 are vertically arranged and slidably connected. The arrangement of the sliding pipe 105 can ensure that the vertical movement of the lower tank 102 will not interfere with the fixedly arranged discharge pipe 14.

[0077] A ring-shaped step groove 1022 is formed in the inner wall of the upper port of the lower tank 102. A limiting groove 1021 is formed in the groove wall of the step groove 1022. A baffle 131 is coaxially fixed to the outer edge of the screen 13. The baffle 131 is higher than the screen 13. A limiting block 133 is fixed to the bottom of the baffle 131. The baffle 131 is located in the step groove 1022 to realize 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 circumferentially limit the screen 13, that is, prevent the screen 13 from rotating relative to the lower tank 102 to improve the position stability of the screen 13.

[0078] The baffle 131 is provided with a picking hole 132.

[0079] When the screen 13 is blocked by sundries or there are too many sundries, the fixing of 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 sundries on the screen 13 can be picked up manually or washed away by a high-pressure water gun to clean the screen 13.

[0080] Alternatively, a rod with a hook is used. The hook of the rod passes through the hooking hole 132 on the retaining fence 131, and then the rod is lifted to remove the screen 13 from the lower tank 102, so as to transfer the screen 13 to other cleaning workstations for in-depth cleaning. The retaining fence 131 can enclose the sundries on the screen 13 to prevent the sundries from slipping off the screen 13 during the transfer process.

[0081] After the cleaning is completed, the hydraulic cylinder 17 drives the lower tank 102 to move upward. The lower tank 102 and the upper tank 101 are attached and clamped to the sealing ring 104 to ensure the sealing performance. Finally, the lower tank 102 and the upper tank 101 are fixed by the fastener 103.

[0082] Embodiment 4

[0083] The difference between Embodiment 4 and Embodiment 1 is that, as Figure 8 、 Figure 9 、 Figure 10 shown, the kitchen waste wet garbage mixing pulping device 20 further includes a steam pipe 16. The tank body 1 has an observation window (not shown in the figure). The main shaft 2 has a main flow channel 23 extending axially, and the main flow channel 23 penetrates to the lower end of the main shaft 2. The auxiliary shaft 3 has an auxiliary flow channel 32 extending axially, and the auxiliary flow channel 32 penetrates to the lower end of the auxiliary 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 communicated with the upper end of the main flow channel 23, and the inlet end of the rotary joint 161 is communicated with the steam pipe 16.

[0084] An annular first confluence chamber 544 is provided on the inner wall of the first rotating sleeve 541, and the first confluence chamber 544 is communicated with the main flow channel 23 through the first air hole 24 opened on the main shaft 2.

[0085] The planet carrier 54 has a branch flow channel 543. An annular second confluence chamber 545 is provided on the inner wall of the second rotating sleeve 542, and the second confluence chamber 545 is communicated with the auxiliary flow channel 32 through the second air hole 33 opened on the auxiliary shaft 3. The two ends of the branch flow channel 543 are respectively communicated with the first confluence chamber 544 and the second confluence chamber 545.

[0086] As Figure 11 shown, filter meshes 25 are fixed at the lower ports of both the main flow channel 23 and the auxiliary flow channel 32. The mesh of the filter mesh 25 is smaller than that of the screen 13, and the filter mesh 25 is attached to the upper surface of the screen 13.

[0087] The pulping state is observed through the observation window. When the pulping is about to end, that is, when the overall slurry is in a pulped state, steam is introduced into the steam pipe 16. 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 sequentially enters the auxiliary flow channel 32 of the auxiliary shaft 3 through the first air hole 24, the first confluence chamber 544, the branch flow channel 543, the second confluence chamber 545 and the second air hole 33 ( Figures 9 - 11The direction of the arrow in ( ) is the steam flow direction. The steam in the main flow channel 23 and the sub-flow channel 32 moves downward to the filter screen 25 and the sieve 13, that is, the steam can heat the filter screen 25 and the sieve 13. With the revolution of the secondary shaft 3, the heating range of the sieve 13 by the steam is large, and the heat of the sieve 13 is transferred to the grease on the sundries of the sieve 13, so that the grease attached to the sundries is heated and dissolved into the slurry to reduce the loss of organic matter in the discharged slurry.

[0088] At the same time, with the circulating flow of the slurry and the heating of the main shaft 2 and the secondary shaft 3 by the steam, the overall 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.

[0089] Secondly, by arranging the annular first confluence chamber 544 and the second confluence chamber 545, to ensure that during the rotation of the main shaft 2 and the secondary shaft 3, the first air holes 24 and the second air holes 33 can always communicate with the first confluence chamber 544 and the second confluence chamber 545, so as to stably transport the steam.

[0090] Embodiment 5

[0091] The difference between Embodiment 5 and Embodiment 3 is that, as Figure 12 、 Figure 13 、 Figure 14 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 blade 21. The lower edge 27 is provided with densely arranged through holes 271 vertically penetrating through.

[0092] The kitchen waste wet garbage mixing pulping device 20 further 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. The upper moving ring 61 is fixed with a plurality of upper rotating blades 63 and three upper sliding cylinders 62. Specifically, the upper sliding cylinders 62 are fixed to the inner wall of the upper moving ring 61 through support rods 64. The upper sliding cylinders 62 are coaxially arranged with the secondary shaft 3. The upper sliding cylinders 62 are sleeved on the outside of the second spiral blade 31, so that the upper sliding cylinders 62 can be axially slidably connected with the second spiral blade 31. Therefore, when the secondary shaft 3 revolves, it will drive the upper sliding cylinders 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.

[0093] The upper rotating blades 63 are arranged radially along the upper moving ring 61, and the upper rotating blades 63 are evenly arranged circumferentially around the axis of the upper moving ring 61. One end of the upper rotating blade 63 far from the axis of the upper moving ring 61 is fixedly connected to the inner wall of the upper moving ring 61. A plurality of vertically upwardly arranged intercepting rods 65 are fixed to one long side of the upper rotating blade 63, and the intercepting rods 65 are arranged at equal intervals along the length direction of the upper rotating blade 63. A plurality of downwardly arranged intercepting hooks 66 are fixed to the other long side of the upper rotating blade 63, and the intercepting hooks 66 are arranged at equal intervals along the length direction of the upper rotating blade 63. The distance between adjacent intercepting hooks 66 is smaller than the distance between adjacent intercepting rods 65, and the hook part of the intercepting hook 66 has two and the directions of the two hook parts are opposite.

[0094] The lower moving ring 71 is fixed with an intercepting net 72, a plurality of lower rotating blades 76 and three downward sliding cylinders 75. Specifically, the outer edge of the intercepting net 72 is fixedly connected to the inner wall of the upper port of the lower moving ring 71. The mesh of the intercepting net 72 is larger than the mesh of the sieve 13. Four through holes 73 penetrate through the intercepting net 72. One of the through holes 73 is adapted to the outer diameter of the first helical blade 21, and the inner walls of the other three through holes 73 are fixedly connected to the downward sliding cylinders 75. The downward sliding cylinders 75 are arranged in the same way as the auxiliary shaft 3. The downward sliding cylinders 75 are sleeved on the outside of the second helical blade 31, so that the downward sliding cylinders 75 can be axially slidably connected to the second helical blade 31. Therefore, when the auxiliary shaft 3 revolves, it will drive the downward sliding cylinders 75 and the lower moving ring 71 to rotate around the axis of the tank body 1, that is, drive the lower intercepting member 7 to rotate.

[0095] The lower rotating blades 76 are arranged radially along the lower moving ring 71, and the lower rotating blades 76 are evenly arranged circumferentially around the axis of the lower moving ring 71. One end of the lower rotating blade 76 far from the axis of the lower moving ring 71 is fixedly connected to the inner wall of the lower moving ring 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. The size of the vertical gap is smaller than the mesh size of the intercepting net 72.

[0096] 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.

[0097] When there are too many impurities in the slurry, such as tableware residues, glass fragments and broken bones, etc., the impurities will affect the fluidity of the slurry driven by the first helical blade 21 and the second helical blade 31 to a certain extent, and at the same time, it will also cause the slurry to adhere and accumulate and be difficult to disperse and mix.

[0098] Therefore, it can be solved by the above technical solutions. Specifically, when the tank body 1 is feeding, 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 sieve 13. After the feeding is completed, the motor 12 drives the main shaft 2 to rotate forward. The forward rotating first helical blade 21 is used to drive the slurry to move upward, and the reverse rotating second helical blade 31 is used to drive the slurry to move downward (refer to Figure 15The first state diagram in [reference], where the arrow directions in the diagram are the slurry flow direction, the moving direction of the upper interceptor 6, and the moving direction of the lower interceptor 7 respectively. And the second helical blade 31 rotates around the axis of the tank body 1 in the positive direction to drive the upper interceptor 6 and the lower interceptor 7 to rotate in the positive direction. The upper rotating blade 63 moves relative to the slurry, and the slurry provides an upward force to the positively rotating upper rotating blade 63, causing the positively rotating upper interceptor 6 to move upward relative to the slurry. While the blade provides a downward force to the positively rotating lower rotating blade 76, causing the positively rotating lower interceptor 7 to move downward relative to the slurry. At this time, the lower interceptor 7 adheres more closely to the screen 13, and the axial position of the lower interceptor 7 remains unchanged.

[0099] During the process of the upper interceptor 6 rotating in the positive direction and moving upward axially, the slurry passes through the gaps between adjacent upper rotating blades 63, and the upper rotating blades 63 and the intercepting rods 65 continuously intercept large particle impurities mixed in the slurry, driving the large particle impurities to gradually move upward with the upper interceptor 6 to the liquid surface of the slurry (refer to Figure 15 the second state diagram in [reference]). And because the slurry at the axis of the tank body 1 is moving upward and the slurry liquid surface is in a state of flowing radially outward, it makes it difficult for the impurities at the slurry liquid surface to flow radially inward to the first helical blade 21, that is, reduces the occurrence of impurities flowing back into the first helical blade 21.

[0100] Then the motor 12 drives the main shaft 2 to rotate in the reverse direction (refer to Figure 15 the third state diagram in [reference]). The reversely rotating first helical blade 21 is used to drive the slurry to move downward, and the positively rotating second helical blade 31 is used to drive the slurry to move upward. And the second helical blade 31 rotates around the axis of the tank body 1 in the reverse direction to drive the upper interceptor 6 and the lower interceptor 7 to rotate in the reverse direction. The slurry provides a downward force to the reversely rotating upper rotating blade 63, causing the reversely rotating upper interceptor 6 to move downward relative to the slurry (the large particle impurities originally on the upper interceptor 6 will break away from the upper interceptor 6 and remain in the state of the slurry liquid surface). While the blade provides an upward force to the reversely rotating lower rotating blade 76, causing the reversely rotating lower interceptor 7 to move upward relative to the slurry, that is, the upper interceptor 6 located at the slurry liquid surface moves downward, and the lower interceptor 7 located at the bottom of the slurry moves downward. The upper interceptor 6 and the lower interceptor 7 move towards each other and contact at the middle layer position of the slurry (refer to Figure 16 the first state diagram in [reference]). Since the wide surface area of the lower rotating blade 76 of the lower interceptor 7 is larger, the upward force of the lower interceptor 7 is greater than the downward force of the upper interceptor 6. The lower interceptor 7 will drive the upper interceptor 6 to continue to move upward, that is, the intercepting net 72 will move upward from the bottom of the slurry to the slurry liquid surface. During this process, the intercepting net 72 will continuously intercept medium particle impurities in the slurry, and the intercepting hook 66 will also hook and intercept some medium particle impurities. The medium particle impurities are brought to the slurry liquid surface by the intercepting net 72 and the intercepting hook 66 (refer to Figure 16The second state diagram in (at this time, both the upper interceptor 6 and the lower interceptor 7 are located at the slurry liquid level); and at this time, since the slurry at the axis of the tank body 1 is moving downward and the slurry liquid level is in a radially inward flow state, some sundries at the slurry blade liquid level will be gathered between the upper edge 26 and the lower edge 27, that is, intercepted by the lower edge 27, thereby reducing the occurrence of sundries flowing back into the first helical blade 21.

[0101] Finally, the motor 12 drives the main shaft 2 to rotate forward (refer to Figure 16 the third state diagram in), the second helical blade 31 revolves around the axis of the tank body 1 forward to drive the upper interceptor 6 and the lower interceptor 7 to rotate forward. Since the upper interceptor 6 has reached the slurry liquid level, it is difficult for the upper interceptor 6 to continue moving upward, that is, the upper interceptor 6 stays at the slurry liquid level. At the same time, the upper interceptor 6 also holds the sundries at the slurry liquid level. Secondly, since the slurry at the axis of the tank body 1 is moving upward and the slurry liquid level is in a radially outward flow state, the sundries at the slurry liquid level are not easily radially inward flowed to the first helical blade 21. And the blade provides a downward force to the downward rotating lower blade 76, so that the downward rotating lower interceptor 7 moves downward relative to the slurry. The intercepting net 72 on the downward moving lower interceptor 7 continuously intercepts the residual medium particles in the slurry. The residual medium particles are located on the bottom surface of the intercepting net 72 until the lower interceptor 7 moves downward to fit the screen 13. At this time, the residual medium particles will be restricted between the intercepting net 72 and the screen 13.

[0102] In summary, by setting the upper interceptor 6 and the lower interceptor 7, and controlling the forward and reverse rotations of the upper interceptor 6 and the lower interceptor 7 to change the vertical movement directions and staying positions of the upper interceptor 6 and the upper interceptor 6, so as to intercept large particle sundries and medium particles respectively, and limit the sundries at the slurry liquid level and the bottom of the slurry respectively, the number of sundries in the slurry flow range is greatly reduced, thereby improving the fluidity and uniformity of the slurry.

[0103] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
