Description

Technical Field

[0001] The present invention relates to the technical field of household waste classification and disposal equipment, and in particular to a kitchen waste crushing and pulping device. Background Art

[0002] Kitchen waste refers to the waste generated in residents' daily life and food processing, catering services, and unit catering activities, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, eggshells, tea dregs, bones, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets, and other industries related to food processing. Kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce foul odors. After proper treatment and processing, it can be converted into new resources. The high organic matter content allows it to be used as fertilizer and feed after strict treatment. It can also produce biogas for fuel or power generation. The oil and fat part can be used to prepare biofuels.

[0003] The weight of kitchen waste can account for up to 40% to 60% of the domestic waste generated by residents. At present, some places adopt a garbage sorting method in which residents sort the waste by themselves and then dispose of it separately. This does not take into account the characteristics of kitchen waste that is easy to decay and has a mixture of solids and liquids. There are no special containers for storage during the sorting process. Residents usually use plastic bags to collect kitchen waste, which belongs to other garbage. This leads to the "broken bag" problem that the plastic bag must be opened (or broken) to pour out the kitchen waste and then the plastic bag can be disposed of separately.

[0004] After being collected, kitchen waste usually needs to be crushed before subsequent resource utilization. There are currently two main types of kitchen waste crushing equipment on the market. One type is installed in the kitchen sink sewer, which is currently more common in the United States and other Western countries. However, due to the eating habits of Chinese residents, the types of kitchen waste, the diameter of drainage pipes and other reasons, it is not suitable for the current situation of kitchen waste treatment in my country; the other type is fixed equipment, which is used in restaurants, canteens and other units that generate a large amount of kitchen waste. It has strong processing capacity but a narrow scope of use and cannot meet the kitchen waste treatment needs of urban residents.

[0005] The Sichuan Provincial Domestic Waste Classification and Disposal Work Plan requires that "residents are encouraged to filter out the moisture from kitchen waste, use special containers to hold kitchen waste, and gradually achieve kitchen waste with "no glass and ceramic, no metal debris, no plastic and rubber, and no napkin paper." At present, the classification collection method of using special containers to collect kitchen waste is relatively rare in the market, and there is also a lack of special supporting equipment for on-site secondary crushing and pulping of kitchen waste after collection for easy transportation.

[0006] It is necessary to develop a kitchen waste slurrying and crushing device for use with a special container, which can crush the collected kitchen waste into slurry for later transportation and resource utilization. Summary of the invention

[0007] The purpose of the present invention is to solve at least one of the above-mentioned deficiencies in the prior art.

DETAILED DESCRIPTION

[0027] Hereinafter, the kitchen waste crushing and pulping device of the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0028] Figure 1 A schematic structural diagram of a kitchen waste crushing and pulping device according to an exemplary embodiment of the present invention is shown; Figure 2 Shows Figure 1 Side view of Figure 3 A schematic structural diagram of a kitchen waste crushing and pulping device according to an exemplary embodiment of the present invention is shown (without supporting parts).

[0029] In an exemplary embodiment of the present invention, the kitchen waste crushing and pulping device may include a bracket, a material storage container fixing mechanism, a crushing and pulping mechanism, and a lifting mechanism. The bracket includes a horizontally arranged bracket body and a track fixedly arranged and perpendicular to the bracket body, and the bracket can support the upper structure of the crushing and pulping device. Specifically, Figure 1 and Figure 2 As shown in the figure, the bracket 2 includes a bracket body 2a arranged horizontally and a track 2b arranged vertically. The bracket body 2a is a rectangular frame structure as a whole. The bottom of the frame is a flat plate, and the track 2b can be fixed to the flat plate. The bracket 2 is used to support and fix other structures of the kitchen waste crushing and pulping device except the bracket 2. However, the present invention is not limited to this, and the bracket 2 can also be other structures as long as it can support the upper structure of the kitchen waste crushing and pulping device.

[0030] The material storage container fixing mechanism is fixedly arranged on the bracket body, and comprises a clamping mechanism, a clamping reducer and a first power component, wherein the first power component is connected to the clamping mechanism through the clamping reducer to drive the clamping mechanism to fix the material storage container. Figure 1 and Figure 2 As shown in , the material storage container fixing mechanism is fixedly arranged in the bracket body 2a, and the material storage container fixing mechanism may include a clamping mechanism 4, a clamping reducer 3 and a first power component 13. Among them, the clamping mechanism 4 is arranged vertically upward, and the clamping mechanism 4 can be moved to clamp or loosen the bottom of the storage container 5. For example, the clamping mechanism 4 can be a clamping hoop. The first power component 13 is connected to the clamping mechanism 4 through the clamping reducer 3 to drive the clamping mechanism 4 to move. For example, the material storage container can be a storage tank, and the storage tank is vertically fixed in the clamping mechanism, and the storage tank can store kitchen waste in a closed manner for fermentation. However, the present invention is not limited to this, and the material storage container fixing mechanism can also be other structures, as long as the storage container can be fixed or loosened.

[0031] The crushing pulping mechanism includes a fixed frame, a second power component, and two groups of pulping knife shaft assemblies, wherein the fixed frame is arranged parallel to the bracket body and is located above the bracket body, and the fixed frame is slidably connected to the track. The two groups of pulping knife shaft assemblies both include a pulping shaft and a pulping knife, the pulping shaft is arranged parallel to the track and its upper end is connected to the fixed frame, the pulping shaft can rotate along the axial direction of the pulping shaft relative to the fixed frame, and the pulping knife is detachably arranged on the pulping shaft; the second power component is fixedly arranged on the fixed frame, and the second power component is connected to the upper end of the pulping shaft to drive the pulping shaft to rotate and drive the pulping knife to rotate. Specifically, if Figure 1 and Figure 2 As shown in , the crushing pulping mechanism mainly includes a fixed frame 7, and a second power component 9 and two groups of pulping knife shaft assemblies arranged on the fixed frame. The fixed frame 7 is arranged in parallel above the bracket body 2a, and the fixed frame 7 is slidably connected to the track 2b, which can drive the pulping knife shaft assembly to move up and down along the track 2b. The pulping knife shaft assembly includes a pulping shaft 11 and a plurality of pulping knives 12. The plurality of pulping knives 12 are axially sleeved on the pulping shaft 11, and the blades of the plurality of pulping knives 12 are radially arranged and staggered with each other on the circumference of the rotating axis of the pulping shaft. For example, the two groups of pulping knife shaft assemblies can be arranged in parallel in the left and right directions, and the two groups of pulping knife shaft assemblies rotate in the same direction. When the two groups of pulping knife shaft assemblies are close to each other, the tangential direction of the pulping knife 12 always moves in the opposite direction to crush and pulp the kitchen waste, thereby preventing the fibers from being entangled on the pulping shaft 11. In addition, as Figure 1 As shown in , the blade of the pulping cutter 12 on the lower end surface of the pulping shaft 11 is set downward to form a certain angle with the axis of the pulping shaft 11. For example, both the first power component and the second power component can be power motors. However, the present invention is not limited to this, and other power devices are also possible.

[0032] One end of the lifting mechanism is fixedly connected to the bracket body, and the other end is fixedly connected to the fixing frame, so as to drive the pulping knife shaft assembly to move up and down along the track to crush and pulp the kitchen waste in the storage container. Figure 1 and Figure 2 As shown in , the lower end of the lifting mechanism 6 is fixedly connected to the bracket body 2a, and the upper end of the lifting mechanism 6 is connected to the fixed frame 7. The lifting mechanism 6 moves to push the fixed frame 7 up and down along the track 2b, thereby driving the two groups of pulping knife shaft assemblies to move up and down. For example, the lifting mechanism 6 may include two groups of lifting cylinders, and the two groups of lifting cylinders are symmetrically arranged. The lifting cylinders include a cylinder body and a piston. The lower end of the cylinder body is fixedly connected to the bracket body, and the piston is arranged in the cylinder body. The upper end of the piston is fixedly connected to the fixed frame. However, the present invention is not limited to this, and the lifting mechanism may also be other structures, as long as it can push the crushing pulping mechanism to move up and down along the track.

[0033] In this exemplary embodiment, Figure 1 and Figure 2 As described in, the device may also include a base 1, the base 1 is fixedly arranged on a plane, the bracket 2 is arranged on the base 1 and is hingedly connected to the base 1, so that the bracket 2 can be arranged tilted or vertically relative to the base 1. For example, the base 1 may include a bottom plate 1a, a support plate 1b and a support 1c, wherein the bottom plate 1a is fixedly arranged on a plane, the support plate 1b is fixedly arranged on the bottom plate 1a, the upper part of the support plate 1b is two symmetrically arranged inclined surfaces, and the cross section of the support plate 1b along the vertical direction is an isosceles triangle, and the hypotenuse of the isosceles triangle is arranged parallel to the bottom plate; the support plate 1b is hingedly connected to the bracket body 2a, so that the bracket 2 can be tilted to the left or right relative to the bottom plate 1a; the support 1c includes two support blocks, and the two support blocks are fixedly connected to the left and right ends of the bracket body 2a respectively. When the support 1c is not used, the bracket 2 and the base are arranged tilted, and the whole crushing pulping device is also tilted, and the kitchen waste in the storage tank is more easily fully turned over and pulped by the pulping knife shaft assembly. When the support 1c is used, the bracket 2 is kept parallel to the ground so that the crushing and pulping device is arranged vertically to the ground. However, the present invention is not limited thereto, and the base can also be other mechanisms as long as it can be hinged with the bracket to make the kitchen waste crushing and pulping device inclined. Figure 3 The schematic diagram shows the structure of the kitchen waste crushing and pulping device when the support is not used.

[0034] In this exemplary embodiment, Figure 1 and Figure 2As shown in , the device may also include a pulley 10, which is arranged at the upper end of the pulping shaft, and the second power component 9 is connected to the pulley 10 through a belt to drive the pulping shaft to rotate. The torque is transmitted to the pulping shaft 11 through the belt and the pulley 10, which can effectively reduce noise and ensure stable operation of the equipment.

[0035] In this exemplary embodiment, the device may further include a deceleration component, which is disposed on the fixing frame and located between the second power component and the pulping knife shaft assembly, and the rotation speed of the second power component is reduced by the deceleration component.

[0036] In this exemplary embodiment, Figure 1 and Figure 2 As shown in , the device may further include a limit member 8, which is arranged on the track 2b to limit the limit position of the fixing frame 7 moving up and down along the track 2b in the vertical direction. Figure 1 As shown in the figure, the limiting component 8 includes two sets of limiting wheels, which are respectively arranged on the track 2b and located at predetermined positions at the upper and lower ends above and below the fixed frame 7. When the fixed frame 7 moves upward or downward on the track 2b and reaches the position in contact with the two sets of limiting wheels, it cannot continue to move upward or downward, thereby limiting the upper and lower limit positions of the crushing pulping mechanism moving on the track 2b.

[0037] During operation, the special storage container for kitchen waste is transferred to the storage container fixing mechanism, and the first power component in the storage container fixing mechanism works to drive the clamping mechanism (clamping hoop) to clamp the storage container and then lock the clamping mechanism.

[0038] The pulping shaft and pulping cutter of the crushing pulping mechanism are located directly above the storage container, and then the power motor of the crushing pulping mechanism is started, and the power motor drives the two sets of pulping shafts to rotate in the same direction through the reducer and belt.

[0039] The lifting cylinder drives the crushing and pulping mechanism to move downward, and the pulping shaft drives the pulping cutter to rotate in the same direction, and the kitchen waste fermented at room temperature is crushed and pulped at the meshing position.

[0040] When the crushing pulping mechanism moves downward to the lower limit, the lifting cylinder works in the reverse direction, the crushing pulping mechanism moves upward to the upper limit and is locked, the motor stops working, the pulping shaft stops working, and a pulping process is completed.

[0041] Replace the special storage container for kitchen waste and proceed to the next pulping.

[0042] In summary, the beneficial effects of the present invention include at least one of the following:

[0043] (1) The kitchen waste collected in special containers can be crushed and pulped, and then directly pumped to tank trucks or storage facilities with larger volumes, thereby improving the efficiency of subsequent transportation and resource utilization;

[0044] (2) The bracket and the base are hingedly connected. When the bracket is used, the whole machine works in a vertical state. When the bracket is not used, the whole machine works in an inclined state, so that the crushed pulping material is easier to be fully turned over and pulped;

[0045] (3) The two sets of pulping knife shaft assemblies rotate in the same direction. When the two sets of pulping knife shaft assemblies are close to each other, the tangential directions of the pulping knives always move in opposite directions to crush and pulp the kitchen waste, thereby preventing the fibers from being entangled on the pulping shaft and affecting the crushing and pulping effect.

[0046] Although the present invention has been described above in conjunction with the exemplary embodiments and the accompanying drawings, it should be apparent to those skilled in the art that various modifications may be made to the above-described embodiments without departing from the spirit and scope of the claims.
