[0002] Garbage classification refers to a series of activities that involve storing, disposing of and transporting garbage according to certain regulations or standards, thereby transforming it into public resources.

[0003] With the rapid development of my country's economy, garbage classification has become a hot topic at present, and garbage classification actions are being carried out in full swing all over the country.

[0004] As an important type of garbage, kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce bad odor. After proper treatment and processing, it can be transformed into new resources. The high organic content makes it possible to be used as fertilizer and feed after strict treatment.

[0005] When processing kitchen waste, it is necessary to separate solid and liquid and crush it. The existing crushing and solid-liquid separation device, such as the structure disclosed in application No. 2017208281515, uses two motors to drive the crushing knife set on the rotating shaft to achieve primary crushing, and then uses the cylinder-driven teeth to perform secondary crushing and discharging, and finally uses a vibration motor to increase the solid-liquid separation effect.

[0023] A garbage disposal device comprises any one of the above-mentioned crushing and solid-liquid separation devices.

[0024] The advantages of the technical solution of the present invention are mainly reflected in:

[0025] 1. This solution uses a longitudinally placed spiral conveyor shaft to move the solid upward and the liquid downward, thereby effectively achieving solid-liquid separation. At the same time, the spiral blades and cutters are used to produce shear force, which can crush the solids while conveying. The entire equipment only needs one power source to achieve garbage crushing and solid-liquid separation. The equipment has high integration, small size, and is easy to process. The equipment cost and use cost are low, and it is convenient for use in homes, canteens, restaurants and other occasions.

[0026] 2. The upper part of the spiral blade of this scheme adopts a variable pitch structure, which can effectively increase the extrusion force continuously during the conveying process, thereby improving the effect of solid-liquid separation.

[0027] 3. A notch is formed on the spiral blade of the present invention, and the cutter is inserted into the notch, which can maximize the shearing area, thereby improving the crushing effect and simplifying the structure.

[0028] 4. The spiral blades of this scheme are formed with micropores, which facilitate the downward flow of the liquid generated during squeezing, thereby increasing the dryness of the output garbage and improving the solid-liquid separation efficiency.

[0029] 5. The solid-liquid separation barrel of this scheme is suspended, which can prevent the discharged liquid from flowing back into the solid-liquid separation barrel. At the same time, it increases the liquid storage space, which is conducive to reducing the discharge pressure.

[0030] 6.

[0031] 7. This solution can effectively increase the drainage rate and improve the drainage efficiency through the design of the guide plate and the drainage blade.

[0032] 8. This solution further adds an automatic feeder, and the automatic feeder has its own drainage structure, which can effectively increase the drainage channel, thereby accelerating the discharge of liquid, which is beneficial to improving the solid-liquid separation efficiency and improving the subsequent garbage transportation efficiency and crushing effect.

[0033] 9. The addition of a feed hopper in this solution is beneficial to increasing the storage space of the feed area. At the same time, adding filter holes on the side panels can further increase the liquid discharge channel when there is a large amount of kitchen waste, thereby accelerating the discharge of the liquid. Combined with the setting of the baffle, it can effectively prevent the separated liquid from flowing back into the garbage and affecting the separation effect.

[0034] 10. The garbage disposal device of this scheme can effectively separate solid organic matter, water and oil, realize the recycling and reuse of solid organic matter and oil, and discharge the water after filtering, which can effectively improve the harmfulness of drainage and has good environmental friendliness.

[0045] The purpose, advantages and features of the present invention will be illustrated and explained by the non-limiting description of the following preferred embodiments.

Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0047] The crushing and solid-liquid separation device disclosed in the present invention is described below in conjunction with the accompanying drawings. It can be used for garbage treatment, especially for the treatment of kitchen waste. Of course, it can also be used for crushing and solid-liquid separation of other materials, for example, it can be used for crushing fruits, vegetables, and medicinal materials. The following embodiments are described by taking the treatment of kitchen waste as an example. Figure 1 As shown, it includes a box body 100 and a screw conveying shaft 200 and a solid-liquid separation barrel 400 located in the box body 100.

[0048] The box 100 can be designed into corresponding shapes according to different needs, such as the attached Figure 1 , Attachment Figure 2 As shown, the box body 100 is a hollow cuboid or cylinder or regular polygonal prism. The box body 100 is provided with a feed port 110, a discharge port 120 and a liquid discharge port 130. The feed port 110 is used for the kitchen waste to be processed to enter the screw conveying shaft 200 in the box body 100 for conveying and crushing, the discharge port 120 is used for discharging the crushed dry waste to the outside of the box body 100, and the liquid discharge port 130 is used for discharging the waste liquid after solid-liquid separation to the outside of the box body 100.

[0049] Their positions on the box 100 can be adjusted according to different application scenarios. In a preferred embodiment, as shown in the attached Figure 1As shown, the feed port 110 is located at the middle and lower position of the box body 100, and is at the same height as the inlet on the side plate 150 of the solid-liquid separation barrel 200. The discharge port 120 is located at the upper end of the box body 100, and can be located at the top area of ​​the side wall of the box body 100, or on the top plate 160 of the box body 100, preferably on the top plate 160. The drain port 130 is located at the lower end of the box body 100, and can also be located at the bottom of the side wall of the box body 100 or on the second bottom plate 140 of the box body, as shown in the attached Figure 4 As shown, it is located on the second bottom plate 140 .

[0050] As attached Figure 1 As shown, the feed port 110 is connected to the inlet 430 of the solid-liquid separation barrel 400 and is located opposite to the inlet 430 of the solid-liquid separation barrel 400. The inlet 430 of the solid-liquid separation barrel 400 is located at the bottom of the barrel wall 420 thereof. An observation port 470 is provided next to the inlet 430. Figure 3 As shown, an observation window 170 covering the observation port 470 is provided on the side plate of the box body 100 .

[0051] As attached Figure 1 , Attachment Figure 2 As shown, the solid-liquid separation barrel 400 is suspended in the box body 100, specifically fixed to the bottom of the top plate 160 of the box body 100, and the discharge port 120 is located in the area of ​​the solid-liquid separation barrel 300 enclosed by the top plate 160. After the kitchen waste enters the bottom of the solid-liquid separation barrel 400 through the feed port 110 and the inlet 430, it is transported upward by the screw conveyor shaft 200.

[0052] As attached Figure 1 As shown, the spiral conveying shaft 200 includes a hollow shaft 220 rotatably arranged on the box body 100, the axis of the hollow shaft 220 is at least parallel to the axis of the box body 100, and is preferably coaxial with the box body 100 and the solid-liquid separation barrel 400, the hollow shaft 220 passes through the first bottom plate 410 of the solid-liquid separation barrel 400, and the two ends of the hollow shaft 220 are respectively connected to the bearings 240 arranged on the top plate 160 and the second bottom plate 140 of the box body 100 through joints 230, and at least the joint 230 connected to the second bottom plate 140 is provided with a sealing ring 250 located above the bearing 240.

[0053] As attached Figure 1 , Attachment Figure 2As shown, one of the joints 230 is connected to a driving device 300 that drives the hollow shaft 220 to rotate. The driving device 300 can be a reduction motor. At this time, the driving device 300 is located above or below the spiral conveying shaft 200, and its torque output shaft is coaxial with the hollow shaft 220. In another embodiment, the driving device 300 can also be driven by a motor 310 and a transmission mechanism 320. The transmission mechanism can be a transmission structure composed of a belt and a synchronous wheel 320, or a gear transmission structure, or a transmission structure composed of a sprocket and a chain. At this time, the motor 310 can be fixed to the side of the box body 100, thereby simplifying the installation structure of the motor 310.

[0054] As attached Figure 1 As shown, a spiral blade 210 is provided on the hollow shaft 220, and the spiral blade 210 is located in the solid-liquid separation barrel 400, and extends from the top surface of the first bottom plate 410 of the solid-liquid separation barrel 400 to the bottom of the top plate 160 close to the box body 100. When the driving device 300 drives the hollow shaft 220 to rotate, the kitchen waste located in the solid-liquid separation barrel 400 can be driven by the rotation of the spiral blade 210 to move from bottom to top to the discharge port 120. At the same time, under the action of its own gravity and the centrifugal force generated when the spiral blade 210 rotates, the liquid is discharged from the liquid outlet 440 on the solid-liquid separation barrel 400 into the box body 100 and discharged from the liquid outlet 130.

[0055] Further, as attached Figure 1 As shown, the outer edge 214 of the spiral blade 210 is close to the inner wall of the solid-liquid separation barrel 400 arranged around its periphery, so as to ensure the transportation of kitchen waste to the greatest extent, and at the same time ensure that the spiral blade fully squeezes the kitchen waste in the solid-liquid separation barrel 400 to separate the waste liquid from the solid.

[0056] Furthermore, in order to facilitate the downward flow of the liquid generated during transportation and extrusion, a plurality of micropores (not shown in the figure) are formed on the spiral blades. The size of the micropores is sufficient to allow the liquid to pass through. Preferably, the pore size of the micropores is between 10-20 mm.

[0057] In order to improve the squeezing effect, the spiral blade 210 adopts a variable pitch structure. Specifically, the pitch of the spiral blade 210 decreases from bottom to top, so that when the kitchen waste is transported upward, the squeezing force gradually increases due to the gradual reduction of the space, and the squeezing dehydration can be effectively achieved. More preferably, since the inner wall of the solid-liquid separation barrel 400 is also provided with a cutter 500, in order to facilitate the subsequent installation of the spiral blade 210 into the solid-liquid separation barrel 400, the pitch of at least the portion of the spiral blade 210 located above the highest cutter 500 is reduced from bottom to top.

[0058] At the same time, the cutter 500 cooperates with the spiral blade 210 to cut, so that the kitchen waste can be effectively crushed. Figure 4 As shown, multiple layers of cutters 500 are also provided on the inner surface of the barrel wall of the solid-liquid separation barrel 400. Each layer has multiple cutters 500 and they are evenly distributed. Preferably, each cutter 500 has four cutters, and the number of layers of the cutters 500 is designed according to different sizes, preferably 2-4 layers. Figure 5 , Attachment Figure 6 As shown, each of the cutters 500 is horizontally arranged and extends into the notch 211 formed on the spiral blade 210, and the upper and lower surfaces of the cutter 500 are respectively close to the upper and lower cutting edges 212 and 213 of the notch 211, so that when the spiral blade 210 rotates, it can cooperate with the cutter 500 to form a shear force to shear and crush the kitchen waste.

[0059] In order to facilitate the assembly of the cutter 500 and the solid-liquid separation barrel 400, the solid-liquid separation barrel 400 is assembled from multiple components, and the cutter 500 is located on some of the components, thereby facilitating assembly. The multiple components constituting the solid-liquid separation barrel 400 will be described in detail below.

[0060] In order to achieve solid-liquid separation, Figure 2 As shown, a liquid outlet 440 is formed on the solid-liquid separation barrel 400 for discharging liquid from the inside to the outside. The position of the liquid outlet 440 can be designed as needed. For example, the liquid outlet can be set on the first bottom plate 410 of the solid-liquid separation barrel 400, or the filter hole can be set on the barrel wall 420 of the solid-liquid separation barrel 400. Of course, the liquid outlet can also be set on both the first bottom plate 410 and the barrel wall 420.

[0061] In a preferred embodiment, the first bottom plate 410 is provided with the liquid outlet 440, and the lower area of ​​the barrel wall 420 is provided with the liquid outlet 440. Figure 2 As shown, the barrel wall 420 of the solid-liquid separation barrel 400 includes a tube body 421, a support ring 422 and a filter sleeve 423 at the bottom, which are assembled as one. They are coaxially arranged and fixed together in the order of tube body 421, support ring 422, tube body 421, support ring 422 and filter sleeve 423 from top to bottom. Of course, the number and length of the tube body 421, support ring 422 and filter sleeve 423 can be adaptively adjusted according to other needs. The cutter 500 is set on the inner wall of the support ring 422. Since the support ring 422 is shallow and small in size, the cutter 500 and the support ring 422 can be processed and formed by welding, integral injection molding, etc.

[0062] The reason why the upper end uses a tube body 421 without a liquid outlet 440 and the lower end uses a filter sleeve 423 with a liquid outlet 440 is because: in the lower area of ​​the solid-liquid separation barrel, the pressure received by the garbage is relatively large and the crushing is not thorough, so it is not easy to clog the liquid outlet 440. When moving to the upper area, due to the large squeezing force and the more complete crushing of the garbage, if the solid-liquid separation barrel is also provided with a liquid outlet 440, it is easy to cause blockage and the crushed material is discharged from the liquid outlet 440 to the outside of the solid-liquid separation barrel and mixed with the liquid discharged from the liquid outlet 440, which causes the problem of insufficient solid-liquid separation.

[0063] Meanwhile, the liquid outlet holes 440 may be mesh holes or circular holes distributed in a dot matrix. Preferably, the liquid outlet holes 440 are elongated holes, thereby increasing the drainage rate and ensuring the structural strength of the solid-liquid separation barrel 400.

[0064] Since the solid-liquid separation barrel 400 is in a suspended state, there is a certain height difference between the solid-liquid separation barrel 400 and the liquid discharge port 130, so that it has a certain liquid storage capacity and can effectively store the liquid discharged from the solid-liquid separation barrel 400, reducing the possibility of liquid reflux into the solid-liquid separation barrel 400, which is conducive to improving the separation efficiency.

[0065] Further, in order to accelerate the discharge of the liquid in the box body 100, as shown in the attached Figure 4 As shown, a guide plate 600 is arranged on the second bottom plate 140 of the box body 100 and is arranged around the outer periphery of the spiral conveying shaft 200. The guide plate 600 is perpendicular to the second bottom plate 140 and is approximately C-shaped. The drain port 130 is located in the space enclosed by the guide plate 600. At the same time, a bending portion 620 is provided at one end of the guide plate 600, which is bent toward the inside of the space enclosed by the guide plate 600. The drain port 130 is located in a triangular area 630 enclosed by the bending portion 620 and the main area of ​​the guide plate 600.

[0066] As attached Figure 4 As shown, the outer wall of the spiral conveying shaft 200 is provided with a drainage blade 700 located in the guide plate 600. The drainage blade 700 rotates with the hollow shaft 220, and introduces the liquid on the outside of the guide plate 600 into the area enclosed by the guide plate 600 and transports it to the drainage port 130 at the triangular area 630. When the water flow is blocked at the bending portion 620, the water flow can be accelerated to enter the drainage port 130, thereby greatly accelerating the drainage speed.

[0067] For the convenience of feeding, the feed inlet 110 may be connected to a hopper (not shown in the figure). The hopper may be fixed on the side plate 150 of the box body 100 or on a bracket. The bottom plate of the hopper is an inclined plate.

[0068] In a more preferable manner, as shown in the appended Figure 1 and the appended Figure 2 figures, the feed inlet 110 is connected to the output port 820 of an automatic feeder 800. The automatic feeder 800 may have various feasible structures. In a preferred embodiment, as shown in the appended Figure 2 and the appended Figure 7 figures, it includes a receiving chute plate 810 arranged horizontally or obliquely. The receiving chute plate 810 is a plate member with a C-shaped, U-shaped or匚-shaped longitudinal section. Its opening faces upward as the loading port 830. One end of it is fixed on the side plate 150 where the feed inlet 110 is located, and at least has the output port 820 with the same shape as and facing the feed inlet 110. A sealing plate 840 is arranged at the other end of the receiving chute plate 810.

[0069] The automatic feeder 800 further includes a conveying mechanism for driving the materials falling on the receiving chute plate 810 to be conveyed towards the feed inlet 110. The conveying mechanism may be a push plate (not shown in the figure) that can reciprocate along the axis direction of the receiving chute plate 810. The push plate is connected to a linear driving device for driving its linear movement. The linear driving device may be a cylinder, a hydraulic cylinder, etc., and is fixed on the sealing plate 840.

[0070] In a more preferable embodiment, the conveying mechanism adopts screw conveying. At this time, as shown in Figure 7 the figure, the bottom area of the receiving chute plate is arc-shaped. The conveying mechanism includes a rotating shaft 850 coaxial with the receiving chute plate. The rotating shaft 850 is rotatably supported on the sealing plate and the side plate 150 of the box body 100. A screw conveying blade 860 is arranged on the rotating shaft 850. Moreover, one end of the rotating shaft 850 extending outside the sealing plate 840 is connected to a conveying motor 870 for driving its rotation.

[0071] To accelerate solid-liquid separation and increase the liquid discharge channel, as shown in the appended Figure 2 figures, filtrate holes 811 are formed on the receiving chute plate 810. A diversion groove 1000 is arranged below the receiving chute plate 810. Moreover, both sides of the receiving chute plate 810 are fixed on the two side plates of the diversion groove 1000. The two side plates of the diversion groove and the two corresponding side plates of the box body are parts of the same plate member.

[0072] Meanwhile, as shown in the appended Figure 2As shown, the bottom of the guide groove 1000 is an inclined plate 1100, and one end 1110 of the inclined plate 1100 close to the box body is lower than the other opposite end. A notch 151 is formed on the side plate 150 where the feed port 110 is located, and the notch 151 extends upward from the lower end of the side plate 150 to a height close to the feed port 110, and of course it can also be lower; the width of the notch 151 can be the same as the width of the side plate 150 where it is located, and of course it can be greater than or less than the width of the side plate where it is located, and the lower end 1110 of the inclined plate 1100 is connected with one side of the second bottom plate 140 corresponding to the notch 151, so that the liquid entering the guide groove 1000 can flow to the drain port 130 through the notch 151 under the action of the inclined plate 1100 and its own gravity, and the two side plates of the guide groove 1000 are connected with the two side plates of the box body.

[0073] Further, in order to facilitate the feeding and increase the liquid separation channel, as shown in the attached Figure 1 , Attachment Figure 2 As shown, a feed hopper 900 is arranged on the material receiving trough plate 810, and the feed hopper 900 covers the side plate 150 where the feed port 110 is located. The discharge port of the feed hopper 900 is connected to the loading port 830 of the material receiving trough plate 810, and each side plate 910 of the feed hopper 900 and the side plate on the corresponding side of the guide trough 1000 are part of a plate member. At the same time, the end plate 920 of the feed hopper 900 and the side plate where the feed port 110 is located are also part of a plate member.

[0074] The side panel where the feed port 110 is located is provided with filter holes 152, and the filter holes 152 are distributed from a height equivalent to the feed port to near the top of the side panel, and the filter holes 152 are also multiple rows of long holes, so that when a large amount of kitchen waste enters the automatic feeder 800 and there is no time for transportation, the liquid in the kitchen waste located at the feed hopper 900 can enter the box body 100 through the filter holes 152 at the side panel, thereby achieving drainage.

[0075] In a more preferred embodiment, as shown in the attached Figure 2 , Attachment Figure 4 As shown, a baffle plate 2000 located above the feed port 110 is provided in the box body 100, and a through hole 2100 and a leakage hole 2200 are formed on the baffle plate 2000. The hole wall of the through hole 2100 is in contact with the outer wall of the solid-liquid separation barrel 400. The baffle plate 2000 is specifically located in the middle position of the filter sleeve 423, so that the liquid entering the box body 100 through the filter hole 152 and the liquid outlet hole located above the baffle plate 2000 can directly fall into the bottom of the box body 100 through the leakage hole 2200 without falling back into the kitchen waste to be processed entering from the feed port 110, which is beneficial to improving the solid-liquid separation efficiency.
