Description

Technical Field

[0001] This application relates to the field of solid waste treatment technology, and in particular to an integrated device for crushing, pulping and separating kitchen waste. Background Technology

[0002] With urban development and the improvement of people's living standards, the amount of kitchen waste generated is increasing dramatically. Kitchen waste is characterized by high water content, high organic matter content, and easy decomposition. Efficient and clean resource utilization is an important way to solve the problem of "garbage besieging the city" and realize a circular economy.

[0003] In the resource recovery process of food waste, the front-end crushing and sorting is a crucial step. Its purpose is to break down solid organic matter in food waste, such as fruits, vegetables, leftover food, and animal offal, into a uniform slurry, while separating inorganic impurities such as plastics, bones, glass, and metals, creating favorable conditions for subsequent biological or chemical treatment.

[0004] Currently, most mainstream pulping equipment on the market uses crushers to break down organic matter. Multiple crushers are coaxially arranged, and the shaft drives their rotation to crush the material in the pulping bin. However, when using crushers, the presence of impurities often damages them. When the crushers collide with impurities, the blades may become dull, leading to unsatisfactory crushing results, or even breakage, preventing further crushing. Furthermore, crushers can only break individual organic materials; they are ineffective against organic matter attached to impurities, causing some organic matter to be discharged along with the impurities, preventing further crushing.

[0005] Therefore, how to improve the crushing and pulping effect during the treatment of kitchen waste has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In order to improve the crushing and pulping effect during the treatment of kitchen waste, this application provides an integrated crushing, pulping and separating device for kitchen waste.

[0007] The integrated crushing, pulping, and separating equipment for kitchen waste provided in this application adopts the following technical solution: An integrated crushing, pulping, and separating device for kitchen waste includes an inlet / outlet buffer bin, a crushing and pulping bin, and a slurry-slag separation device. The inlet / outlet buffer bin and the crushing and pulping bin are placed side by side, and an inlet gate is provided between them. An impeller and a crushing component are provided inside the crushing and pulping bin. A concentric dual-output gearbox is provided outside the crushing and pulping bin. The concentric dual-output gearbox includes a first output shaft, and a bushing assembly is fitted over the first output shaft. The impeller is connected to the first output shaft, and the crushing component is connected to the bushing assembly. The impeller and the crushing component rotate in opposite directions. The slurry-slag separation device is located on the side of the inlet / outlet buffer bin away from the crushing and pulping bin, and is used to separate the slurry from the slag.

[0008] By adopting the above technical solution, the impeller agitates the liquid in the crushing and pulping chamber, and the crushing components crush large pieces of material in the crushing and pulping chamber. The rotation of the impeller forms a hydraulic vortex, which tears, kneads, and rubs the material in it, separating the organic matter attached to the impurities. The crushing components impact and crush the solids in the slurry, and the crushing components rotate in the opposite direction to the impeller, further enhancing the crushing effect of the crushing chain. The combination of hydraulic vortex and mechanical crushing for pulping not only solves the problem of organic matter attached to impurities being unable to be crushed, but also eliminates the possibility of dulling or breaking of the crushing blades. The impeller drives the liquid to form a hydraulic vortex, and the vortex drives the solids to collide with the crushing components, which not only improves the crushing and pulping effect, but also eliminates the need for frequent shutdowns to replace the crushing blades.

[0009] Preferably, the concentric dual-output transmission further includes an input frame, and the bushing assembly includes a first bushing and a second bushing; one end of the input frame is connected to a drive component, and the other end of the input frame is concentrically connected to the first output shaft; the end of the input frame connected to the first output shaft is provided with gear teeth, and the end of the input frame with gear teeth is connected to the first bushing through a first gear and a second gear; the second gear is sleeved outside the first bushing, and there are several first gears, which are equally spaced and all mesh with the second gears and the gear teeth; the second bushing is connected to the end of the first bushing away from the input frame, and a combined shaft seal is provided between the second bushing and the first output shaft, the combined shaft seal being used to cover the gap between the second bushing and the first output shaft.

[0010] By adopting the above technical solution, the same input frame is connected to two concentric outputs, realizing concentric counter-rotation between the first output shaft and the first bushing, thereby achieving the effect of the impeller and crushing component rotating in opposite directions; the drive component drives the input frame to rotate, and the input frame is directly connected to the first output shaft, with the rotation direction of the first output shaft being the same as the rotation direction of the input frame; a gear tooth is provided at one end of the input frame near the first output shaft, along with a first gear and a second gear, with the second gear sleeved outside the first bushing, and the first gear meshing with both the gear tooth and the second gear, wherein the first gear meshes internally with the input frame, thus making the rotation direction of the first bushing opposite to the rotation direction of the first output shaft; the second bushing is connected to the first bushing, extending the position where the crushing component can be connected; a combined shaft seal is provided between the second bushing and the first output shaft to cover the gap between the second bushing and the first output shaft, preventing liquid from entering the reducer through the gap and causing damage to the reducer; multiple first gears are arranged at equal intervals to ensure the force balance between the input frame and the second gear, and to a certain extent, improve the smoothness and reliability of the transmission.

[0011] Preferably, a first motor is provided outside the crushing and pulping chamber, and the concentric dual-output gearbox further includes a gearbox pulley; a motor pulley is provided at the output end of the first motor, and the motor pulley is connected to the gearbox pulley via a belt; the gearbox pulley is connected to the input frame.

[0012] By adopting the above technical solution, a motor pulley is set at the output end of the first motor, and the motor pulley is connected to the gearbox pulley via a belt. The gearbox pulley is connected to the input frame, thereby driving the first motor to rotate the input frame and complete the input.

[0013] Preferably, the impeller is located at the end of the first output shaft away from the input frame, and the impeller is used to agitate the liquid flow in the crushing and pulping chamber to form a vortex; a crushing chain mounting seat is provided at the end of the second shaft sleeve away from the first shaft sleeve, and a crushing chain is provided on the crushing chain mounting seat; one end of the crushing chain is connected to the crushing chain mounting seat, and the other end of the crushing chain is connected to a crushing head, and the crushing chain mounting seat, the crushing chain, and the crushing head together form a crushing assembly.

[0014] By adopting the above technical solution, the impeller is set at the end of the first output shaft away from the input frame, and the crushing component is set at the end of the second shaft sleeve away from the first shaft sleeve. The impeller is used to stir the liquid flow to form a vortex, and the crushing component is used to crush the solids in the vortex. The crushing component includes a crushing chain mounting base, a crushing chain, and a crushing head. The crushing chain mounting base is fixed on the second shaft sleeve. One end of the crushing chain is connected to the crushing chain mounting base, and the other end is connected to the crushing head. A relatively flexible connection is adopted. When the second shaft sleeve drives the crushing chain mounting base to rotate, the crushing chain and the crushing head rotate together to impact and crush the solids.

[0015] Preferably, the inlet and outlet buffer bins are equipped with inclined guide plates; the inclined guide plates divide the inlet and outlet buffer bins into an inlet buffer bin and an outlet buffer bin, with the inlet buffer bin located above the outlet buffer bin; a material inlet and a drain and recycled water inlet are provided above the inlet buffer bin, the material inlet being located in the middle of the inlet buffer bin, and the drain and recycled water inlet being located on the side of the material inlet away from the crushing and pulping bin; the end of the inclined guide plate near the drain and recycled water inlet is higher than the end of the inclined guide plate near the crushing and pulping bin; a feed gate is provided between the inlet buffer bin and the crushing and pulping bin, and the feed gate is used to control the material feeding; an overflow port is provided between the outlet buffer bin and the crushing and pulping bin, and the overflow port is located below the feed gate; a discharge port is provided at the bottom of the outlet buffer bin, and the discharge port is used to discharge the material in the outlet buffer bin.

[0016] By adopting the above technical solution, the inclined guide plate not only separates the inlet and outlet buffer bins, but also guides the material movement, directing the material from the inlet and outlet buffers to the crushing and pulping bin. A material inlet and a leachate and recycled water inlet are provided on the inlet buffer bin. The material inlet is located in the middle of the upper part of the inlet buffer bin, while the leachate and recycled water inlet is located on the side away from the material inlet. When material is fed into the inlet, leachate and recycled water are simultaneously fed into the leachate and recycled water inlet. During the feeding process, the recycled water can also wash the material, reducing the adhesion of organic matter to impurities. A feed gate is provided between the inlet buffer bin and the crushing and pulping bin, and an overflow outlet is provided between the outlet buffer bin and the crushing and pulping bin. The feed gate controls the feeding, and the overflow outlet discharges the slurry carried out of the crushing and pulping bin to the outlet buffer bin. Simultaneously, a discharge outlet is provided at the bottom of the outlet buffer bin to discharge the crushed slurry.

[0017] Preferably, the slurry-sludge separation device includes a slurry-sludge inlet and a separation shell; a second motor is provided at one end of the separation shell, and the output end of the second motor is connected to a variable-space spiral shaft, which is used to separate the slurry-sludge and convey solid sludge; a draining screen is provided below the variable-space spiral shaft, and a slurry outlet is provided below the draining screen in the separation shell; a solid sludge outlet is provided at the other end of the separation shell, and a secondary draining screen is provided between the solid sludge outlet and the variable-space spiral shaft; a slurry-sludge inlet is provided above the variable-space spiral shaft in the separation shell; the slurry-sludge inlet is connected to the discharge outlet.

[0018] By adopting the above technical solution, the slurry-slag separation device separates the solids and liquids in the slurry. A variable-space spiral shaft connected to a second motor is used to compress the slurry, achieving slurry-slag separation. It also conveys the solids, outputting the solids from the solids outlet and the liquid from the slurry outlet. A drain screen is installed below the variable-space spiral shaft to screen the slurry; the liquid flows out of the drain screen, while the solids remain. Under the action of the variable-space spiral shaft, the solids are conveyed upwards and compressed, squeezing out the liquid stored within them. As the variable-space spiral shaft rotates, the solids are continuously conveyed upwards, and secondary compression between the solids squeezes out some liquid. A secondary drain screen is installed below the variable-space spiral shaft to transport the liquid squeezed out secondaryly, preventing it from contacting the solids below. A slurry-slag inlet is installed above the variable-space spiral shaft, connected to the discharge outlet at the bottom of the discharge buffer bin, allowing the crushed slurry-slag to directly enter the slurry-slag separation device.

[0019] Preferably, both the feed and discharge buffer bins and the crushing and pulping bins are equipped with support frames; the crushing and pulping bins are equipped with a crushing chain inspection door and an impeller inspection door; the crushing chain inspection door is located on the side wall of the crushing and pulping bins, and the impeller inspection door is located at the bottom of the crushing and pulping bins.

[0020] By adopting the above technical solution, the feed and discharge buffer bins and the crushing and pulping bins are supported by a support frame. The crushing chain inspection door is used to facilitate the maintenance of the crushing components, and the impeller inspection door is used to facilitate the maintenance of the impeller.

[0021] Preferably, it further includes a connecting pipe, the two ends of which are respectively connected to the crushing and pulping chamber and the discharge buffer chamber. The connecting pipe is equipped with a discharge gate and a liquid level sensor. The liquid level sensor is electrically connected to the inlet gate and the outlet gate respectively. The detection end of the liquid level sensor is located inside the crushing and pulping chamber.

[0022] By adopting the above technical solution, a connecting pipe is used to connect the crushing and pulping chamber and the discharge buffer chamber, and a discharge gate is installed on the connecting pipe. When the entire crushing and pulping operation is completed and the machine needs to be stopped, the discharge gate is opened to discharge all the material in the crushing and pulping chamber. The liquid level sensor obtains the liquid level in the crushing and pulping chamber. When a certain level is reached, the feed gate is driven to close, and no more material is fed.

[0023] Preferably, the slurry-slag separation device is inclined, and the position of the solid slag outlet is higher than the position of the slurry outlet.

[0024] By adopting the above technical solution, the inclined slurry-sludge separation device allows the liquid to flow downwards during slurry-sludge separation, while the solids are conveyed upwards by the variable-space spiral shaft and squeezed. The squeezed liquid also flows downwards, preventing liquid backflow from causing the squeezing separation to fail.

[0025] Preferably, the diameter of the variable space spiral shaft at the end near the second motor is smaller than the diameter of the variable space spiral shaft at the end away from the second motor; and the pitch of the variable space spiral shaft at the end near the second motor is greater than the pitch of the variable space spiral shaft at the end away from the second motor.

[0026] By adopting the above technical solution, by using a gradually increasing shaft diameter and a gradually decreasing pitch, the space of the solid material is reduced when the variable space screw shaft transports the solid material, thereby squeezing the solid material and expelling the liquid remaining inside the solid material.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining crushing components and impellers, the impeller agitates to form a vortex, and the crushing components crush the liquid in the crushing and pulping chamber. The impeller and crushing components rotate in opposite directions, and the vortex tears, kneads and rubs the material in it, separating the organic matter attached to the impurities, thus improving the crushing and pulping effect of kitchen waste. 2. An overflow port is set between the crushing and pulping bin and the discharge buffer bin. During crushing, after the liquid level reaches a certain height, the liquid flow carries the crushed solids out of the overflow port, realizing continuous feeding and discharging without stopping the machine, which increases the crushing and pulping separation efficiency. 3. The variable-space spiral shaft conveys solid materials while simultaneously performing secondary compression on them, reducing the moisture content of the solid materials and facilitating subsequent discharge of the solid materials.

In this embodiment, the liquid level sensor 8 is used to obtain the liquid level height within the crushing and pulping silo 3. The detection end of the liquid level sensor 8 is located within the crushing and pulping silo 3, and the liquid level sensor 8 is electrically connected to the inlet gate 2.

[0033] Reference Figure 2 The feed and discharge buffer bin 1 is provided with a material inlet 101 and a drain and recycled water inlet 102; the crushing and pulping bin 3 includes a bin body 301, and a first motor 302 and a concentric double-output gearbox 306 are provided outside the bin body 301. The output end of the first motor 302 is connected to a motor pulley 303, and the concentric double-output gearbox 306 is connected to a gearbox pulley 305. The motor pulley 303 and the gearbox pulley 305 are connected by a belt 304, and the motor pulley 303 and the gearbox rotate at the same linear speed.

[0034] Reference Figure 3 The bottom of the feed and discharge buffer bin 1 is provided with a discharge port 107. The crushing and pulping bin 3 is also provided with an impeller inspection door 312 and a crushing chain inspection door 311. The impeller inspection door 312 is located at the bottom of the bin body 301, and the crushing chain inspection door 311 is located on the side of the bin body 301. The connecting pipe 7 is located at the bottom of the crushing and pulping bin 3. The two ends of the connecting pipe 7 are respectively connected to the crushing and pulping bin 3 and the feed and discharge buffer bin 1. The discharge gate 4 is provided on the connecting pipe 7.

[0035] Reference Figure 4 The crushing and pulping chamber 3 is equipped with an impeller 307 and a crushing component. The impeller 307 is connected to a first output shaft 30603, and the crushing component is connected to a second bushing 309, which is fitted onto the first output shaft 30603. The bottom of the crushing and pulping chamber 3 is provided with a slurry discharge port 310.

[0036] Reference Figure 5The concentric dual-output transmission 306 includes a transmission housing 30601 and an input frame 30602. The input frame 30602 is concentrically connected to the transmission pulley 305. The input frame 30602 rotates around an axis under the action of the transmission pulley 305. A first output shaft 30603 is connected to one end of the input frame 30602 away from the transmission pulley 305. A first bushing 30605 and a second bushing 309 are fitted around the first output shaft 30603. The first bushing 30605 and the second bushing 309 are connected by a coupling 314. The first output shaft 30603 extends from outside the crushing and pulping chamber 3 to inside the crushing and pulping chamber 3. The second shaft sleeve 309 is fitted onto the portion of the first output shaft 30603 located inside the crushing and pulping chamber 3; the crushing assembly includes a crushing chain mounting base 315, a crushing chain 308, and a crushing head 313. The crushing chain mounting base 315 is located at the end of the second shaft sleeve 309 away from the coupling 314. One end of the crushing chain 308 is connected to the crushing chain mounting base 315, and the other end of the crushing chain 308 is connected to the crushing head. The distance between the crushing chain mounting base 315 and the upper surface of the impeller 307 is greater than the sum of the lengths of the crushing chain 308 and the crushing head 313, to prevent the crushing head 313 from contacting the impeller 307 when it hangs down, thus preventing damage to the impeller 307.

[0037] Reference Figure 5 The second bushing 309 is provided with a combined shaft seal 316 at the end near the impeller 307. The combined shaft seal 316 is used to shield and seal between the bushing and the shaft to prevent impurities or water from entering between the shaft and the bushing, which could lead to unstable shaft transmission or even corrosion.

[0038] Reference Figure 6 The input frame 30602 is generally trumpet-shaped, with the smaller diameter end being solid and the larger diameter end having a stepped groove. The first output shaft 30603 is disposed within the groove, and gear teeth 30607 are provided on the sidewall of the groove. The concentric dual-output reducer also includes a first gear 30606 and a second gear 30604. The second gear 30604 is sleeved outside the first bushing 30605.

The transmission housing 30601 is used to support the input frame 30602.

[0039] In this embodiment, three first gears 30606 are provided. Only one first gear 30606 is shown in the accompanying drawings to illustrate the connection relationship between the components. In other embodiments of this application, the number of first gears 30606 can be appropriately increased or decreased according to the actual situation.

[0040] Reference Figure 7 The concentric dual-output reducer is located outside the crushing and pulping chamber 3, and the first motor 302 is also located outside the crushing and pulping chamber 3.

[0041] Reference Figure 8 An inclined guide plate 103 is provided inside the feed buffer 1, which divides the feed buffer 1 into a feed buffer 104 and a discharge buffer 106. The feed buffer 104 is located above the discharge buffer 106. The feed gate 2 is located between the feed buffer 104 and the crushing and pulping 3. Multiple overflow ports 105 are arranged side by side between the discharge buffer 106 and the crushing and pulping 3. In this embodiment, the discharge gate 4 is a slide gate valve.

[0042] Reference Figure 9 The impeller 307 agitates the liquid in the crushing and pulping chamber 3, forming a vortex as shown in the figure. The rotation direction of the impeller 307 is opposite to the rotation direction of the crushing chain 308, so that the crushing chain 308 and the crushing head 313 crush the material to the maximum extent.

[0043] Reference Figure 10 The slurry-slag separation device 5 includes a second motor 501, a separation shell 503, a slurry-slag inlet 502, a draining screen 506, a secondary draining screen 504, a solid slag outlet 505, and a slurry outlet 507. The draining screen 506 is located below the slurry-slag inlet 502. The separation shell 503 has a bend, and the draining screen 506 and the secondary draining screen 504 are respectively located at both ends of the bend. In this embodiment, a pipe is provided at the bottom of the secondary draining screen 504 to connect to the bottom of the draining screen 506, so that the liquid drained from the secondary draining screen 504 flows into the bottom of the draining screen 506 through the pipe and then flows out from the slurry outlet 507. The slurry outlet 507 is located below the draining screen 506, and the solid slag outlet 505 is located below the secondary draining screen 504.

[0044] Reference Figure 11The separation shell 503 is provided with a variable space spiral shaft 508. One end of the variable space spiral shaft 508 is connected to the output end of the second motor 501. The variable space spiral shaft 508 can rotate around the shaft under the action of the second motor 501. The variable space spiral shaft 508 is used to transport solids from the slurry feed port 502 to the solid discharge port 505, and to squeeze the solids during the transportation process to reduce the water content of the solids.

[0045] The implementation principle of this embodiment is as follows: The first motor 302 is turned on, driving the impeller 307 and the crushing chain 308 to rotate, opening the feed gate 2, and the leachate from kitchen waste and the recycled water used for slurry preparation enter the feed buffer silo 104 through the leachate and recycled water inlet 102. Then, kitchen waste is fed into the feed buffer silo 104 through the material inlet 101. Kitchen waste, leachate, and recycled water all enter the crushing and slurry preparation silo 3. The liquid level sensor 8 detects the liquid level in the crushing and slurry preparation silo 3 in real time. When the liquid level reaches the specified level, the feed gate 2 is closed to stop feeding. Then, the waste is crushed in the crushing and slurry preparation silo 3 by the impeller 307, the crushing chain 308, and the crushing head 313. After crushing for 5-10 minutes, the discharge gate 4 is opened, and the slurry is discharged from the discharge gate 3. The connecting pipe 7 flows through the discharge buffer bin 106, and then enters the slurry-sludge separation device 5 from the slurry-sludge inlet 502. The liquid in the slurry-sludge flows directly out from the slurry outlet 507 under the action of the drain screen 506, while the solid sludge is left on the drain screen 506. Under the pushing and squeezing action of the variable space spiral shaft 508, the solid sludge moves upward along the shell, and after passing through the bend, it is output from the solid sludge outlet 505, completing one crushing and pulping separation. When the liquid level sensor 8 detects that the liquid level has reached the minimum liquid level, the discharge gate 4 is closed and the inlet gate 2 is opened, completing one cycle. When the kitchen waste is finished and the machine needs to be stopped, the liquid level sensor 8 is closed, the discharge gate 4 is opened, and all the slurry-sludge in the crushing and pulping bin 3 is transported to the slurry-sludge separation device 5 for slurry-sludge separation. Example 2

[0046] Reference Figure 8 The overflow port 105 is located at the bottom of the feed gate 2. The overflow port 105 is used to input the slurry residue after crushing in the crushing and pulping chamber 3 into the discharge buffer chamber 106. When the organic matter is crushed to a certain size, it has a certain centrifugal force under the stirring action of the impeller 307. As the slurry flows out of the crushing and pulping chamber 3 from the overflow port 105, larger pieces of material are left in the crushing and pulping chamber 3 to continue to be crushed because of their own weight and the small size of the overflow port 105. Only when they are crushed into slurry residue smaller than the size of the overflow port 105 can they overflow into the discharge buffer chamber 106.

[0047] The difference between this embodiment and embodiment 1 is that this embodiment does not require the liquid level sensor 8 to detect the liquid level height, and can achieve the discharge of crushed organic matter.

[0048] The implementation principle of this embodiment is as follows: The discharge gate 4 is closed, the feed gate 2 is opened, and then the first motor 302 is turned on, driving the impeller 307 and the crushing chain 308 to rotate. Leachate from kitchen waste and recycled water for slurry preparation enter the feed buffer silo 104 through the leachate and recycled water inlet 102. Then, kitchen waste is fed into the feed buffer silo 104 through the feed inlet, and then enters the crushing and slurrying silo 3 for crushing and slurrying operations. Without closing the feed gate 2, materials and recycled water are continuously fed into the crushing and slurrying silo 3, while simultaneously crushing and slurrying the materials. When the slurry level in the crushing and slurrying silo 3 reaches a certain height, it overflows from the overflow port 105 into the discharge buffer silo 106, and then directly enters the slurry-sludge separation device 5. As materials enter, slurry and sludge continuously overflow from the overflow port 105. In the discharge buffer bin 106, the crushed material overflows from the overflow port 105 into the discharge buffer bin 106, while the uncrushed material remains in the crushing and pulping bin 3 for further crushing. The slurry and sludge flowing into the discharge buffer bin 106 directly enters the slurry and sludge separation device 5 from the slurry and sludge inlet 502. The liquid in the slurry and sludge flows directly out from the slurry outlet 507 under the action of the drain screen 506, while the solid sludge remains on the drain screen 506. Under the pushing and squeezing action of the variable space spiral shaft 508, the solid sludge moves upward along the shell and is output from the solid sludge outlet 505 after passing through the bend. When the kitchen waste processing is completed and the machine needs to be stopped, the inlet gate 2 is closed and the outlet gate 4 is opened. The remaining slurry and sludge that cannot flow out from the overflow port 105 is input into the slurry and sludge separation device 5 through the outlet gate 4 for slurry and sludge separation.
