Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, specifically to a crusher and a kitchen waste treatment system. Background Technology

[0002] Organic wet waste refers to waste composed of organic materials such as kitchen waste and agricultural by-products. Kitchen waste accounts for a large proportion and mainly comes from food processing plants, household waste, commercial kitchens, and restaurants. Due to the strong shearing, tearing, and impact forces of toothed rollers (toothed blade crushing rollers), toothed roller crushers are widely used in the crushing of kitchen waste and can quickly process soft fibers and hard materials in mixed waste.

[0003] CN118179664A discloses a pre-treatment device for kitchen waste in a residential waste transfer station. The device uses a toothed kitchen waste crushing roller to crush the waste in the crushing box. The impact plate connected to the toothed roller intermittently strikes the vibrating plate, thereby driving the cleaning brush to overcome the elasticity of the spring and clean the surface of the toothed roller, thus avoiding the problem of kitchen waste sticking and tangling on the toothed roller.

[0004] However, since the cleaning brush in this patent can only clean the surface of the toothed roller intermittently, it is relatively ineffective at cleaning high-fiber debris entangled on the toothed roller. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a shredder that solves the technical problem that the cleaning brush in the prior art can only intermittently clean the surface of the toothed roller, and the cleaning effect on high-fiber garbage wrapped on the toothed roller is relatively poor.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a pulverizer, comprising:

[0008] The crushing chamber has an inlet and an outlet;

[0009] Two toothed rollers are located inside the crushing chamber, interlocking with each other and capable of rotating relative to each other;

[0010] The cutter barrel is located inside the crushing chamber and on the side of the toothed roller near the inlet, with its axial direction intersecting the arrangement direction of the inlet and the outlet.

[0011] A cutter head, disposed within a cutter cylinder, has the same axial direction as the cutter cylinder and is capable of rotating relative to the cutter cylinder about its own axial direction; and

[0012] Two sets of cutters, each set having multiple cutters, with the multiple cutters alternately arranged along the axial direction of the cutter cylinder between the cutter cylinder and the cutter disc.

[0013] In some embodiments, the axis of the cutter head is located on the side of the axis of the cutter barrel closer to the inlet, and rotates eccentrically relative to the cutter barrel.

[0014] In some embodiments, the shredder further includes an air nozzle disposed within the shredding chamber and connected to an external air source, for spraying airflow toward the cutter.

[0015] In some embodiments, the cutter includes a blade, and the blade has cutting edges on both sides of the cutter disc in the direction of rotation relative to the cutter cylinder.

[0016] In some embodiments, the pulverizer further includes a drive unit mounted on the pulverizing chamber and connected to at least one of the toothed rollers for driving two of the toothed rollers to rotate relative to each other, and connecting at least one of the cutter disc and the cutter cylinder for driving the cutter disc to rotate relative to the cutter cylinder about its own axial direction.

[0017] In some embodiments, the pulverizer further includes a torque sensor disposed on the toothed roller for monitoring the torque of the toothed roller.

[0018] In some embodiments, the toothed roller includes a roller shaft and a plurality of crushing teeth. The roller shaft is rotatably mounted in the crushing chamber, and the plurality of crushing teeth are mounted on the roller shaft and spaced apart along the axial direction of the roller shaft, with a gap formed between two adjacent crushing teeth.

[0019] The crusher also includes a hook blade installed inside the crushing chamber, and has a hook section extending into the gap. The hook section is semi-arc-shaped, and its arc-shaped opening faces the roller shaft.

[0020] In some embodiments, the hook blade can rotate relative to the crushing chamber, and the angle between the hook section and the horizontal direction can be adjusted during rotation;

[0021] The pulverizing chamber also includes an adjustment unit, which is installed in the pulverizing chamber and connected to the hook blade, for driving the hook blade to rotate relative to the pulverizing chamber.

[0022] In some embodiments, the adjustment unit includes a mounting base, a rotating shaft, and an adjustment motor. The mounting base is connected to the rotating shaft and is rotatably mounted in the crushing chamber via the rotating shaft. The rotating shaft extends out of the crushing chamber. The output shaft of the adjustment motor is connected to the rotating shaft and drives the rotating shaft to rotate.

[0023] The hook blade is detachably mounted on the mounting base.

[0024] In addition, this utility model also provides a kitchen waste treatment system, which includes a shredder as described in any of the above-mentioned items.

[0025] Compared with the prior art, in the shredder provided by this utility model, the cutter cylinder and cutter disc are located on the feeding side of the toothed roller, so that when kitchen waste enters the shredding chamber from the inlet, it first passes through the cutter cylinder and cutter disc, and then through the toothed roller. Since the axial direction of the cutter cylinder and cutter disc intersects with the material feeding direction, when the cutter disc and cutter cylinder rotate relative to each other, the high-fiber material that has just entered the shredding chamber from the inlet can be sheared by the cutter at the top, realizing one-time shearing of high-fiber material.

[0026] After the initial shearing, the high-fiber material is further sheared by the rotating cutter at the bottom as it moves downwards. Simultaneously, the rotating cutter cylinder or disc agitates the high-fiber material and other waste in the pulverizing chamber, promoting homogenization and allowing the high-fiber material to be repeatedly sheared during this agitation, reducing its size. Meanwhile, other waste carries away the smaller high-fiber materials as it moves downwards, effectively preventing them from tangling on the toothed rollers, improving cleaning efficiency, and ensuring the toothed rollers' ability to pulverize kitchen waste.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] To address the problem that existing cleaning brushes can only intermittently clean the surface of the toothed roller, resulting in relatively poor cleaning of high-fiber waste entangled on the toothed roller, this invention provides a shredder that allows high-fiber materials to be repeatedly sheared, reducing their size. This allows other waste to be carried away simultaneously during the downward flow of the shredder, effectively preventing high-fiber materials from entangled on the toothed roller, improving the cleaning effect, and thus ensuring the toothed roller's ability to shred kitchen waste.

[0036] It should be noted that the shredder described in this utility model is used in, but not limited to, kitchen waste treatment systems. For ease of explanation, this utility model only uses the application of the shredder in a kitchen waste treatment system as an example. The principle of the shredder in other types of equipment is essentially the same as that in the kitchen waste treatment system, and will not be described in detail here.

[0037] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the structure of a pulverizer in one embodiment of the present invention. The pulverizer includes a pulverizing chamber 1, a blade cylinder 3, a blade disc 4, two sizes, and two sets of cutters 5. The pulverizing chamber 1 has an inlet 1a and an outlet. Two toothed rollers 2 are disposed inside the pulverizing chamber 1, meshing with each other and capable of relative rotation. The blade cylinder 3 is disposed inside the pulverizing chamber 1 and located on the side of the toothed rollers 2 near the inlet 1a, with its axial direction intersecting the arrangement direction of the inlet 1a and the outlet. The blade disc 4 is disposed inside the blade cylinder 3, with its axial direction being the same as that of the blade cylinder 3, and capable of rotating relative to the blade cylinder 3 around its own axial direction. Each set of cutters 5 has multiple cutters, which are alternately arranged along the axial direction of the blade cylinder 3 and the blade disc 4. Specifically, the two sets of cutters 5 are respectively disposed on the blade cylinder 3 and the blade disc 4, and can mesh with each other. Each set of cutters 5 has multiple cutters, and the multiple cutters 5 in the same set are spaced apart around the axial direction of the blade disc 4.

[0038] In the shredder provided by this utility model, the cutter cylinder 3 and the cutter disc 4 are located on the feeding side of the toothed roller 2, so that when kitchen waste enters the shredding chamber 1 from the inlet 1a, it first passes through the cutter cylinder 3 and the cutter disc 4, and then through the toothed roller 2. Since the axial direction of the cutter cylinder 3 and the cutter disc 4 intersects with the material feeding direction, when the cutter disc 4 and the cutter cylinder 3 rotate relative to each other, the high-fiber material that has just entered the shredding chamber 1 from the inlet 1a can be sheared by the cutter 5 that rotates to the top, realizing one-time shearing of the high-fiber material.

[0039] The high-fiber material, after being sheared once, is further sheared by the rotating cutter 5 as it moves downwards. Simultaneously, the rotating cutter cylinder 3 or cutter disc 4 agitates the high-fiber material and other waste within the pulverizing chamber 1 circumferentially, facilitating waste homogenization and allowing the high-fiber material to be repeatedly sheared during circumferential agitation, reducing its size. At this point, other waste can simultaneously carry away the smaller-sized high-fiber material as it moves downwards, effectively preventing the high-fiber material from tangling on the toothed roller 2, improving the cleaning effect, and thus ensuring the toothed roller 2's pulverizing ability for kitchen waste.

[0040] It should be understood that the inlet 1a and outlet are respectively connected to the inner cavity of the crushing chamber 1, and the two toothed rollers 2 are placed between the inlet 1a and the outlet. Furthermore, based on the flat structure of the cutter 5 itself, and the fact that the two sets of cutters 5 can effectively cut high-fiber materials during relative rotation, they are less likely to be entangled by high-fiber materials. In addition, in one embodiment, one of the cutter cylinder 3 or the cutter disc 4 is configured to rotate relative to the crushing chamber 1, while the other is configured to be fixed relative to the crushing chamber 1.

[0041] In another embodiment, both the cutter cylinder 3 and the cutter disc 4 are configured to rotate relative to the crushing chamber 1, and their rotation directions are opposite. Specifically, in this embodiment, the rotational speed of the cutter disc 4 is set to be 20% to 30% faster than that of the cutter cylinder 3, generating a strong relative shearing force. The distance between the two sets of blades is maintained at 3 to 5 millimeters, ensuring both shearing effect and avoiding interference, so that each cutter 5 can sequentially engage with multiple cutters 5 of the other set when the cutter disc 4 rotates relative to the cutter cylinder 3, thereby shearing the material.

[0042] In one embodiment, the axis of the cutter disc 4 is located on the side of the axis of the cutter cylinder 3 near the inlet 1a, and rotates eccentrically relative to the cutter cylinder 3; each cutter 5 can sequentially engage with another set of multiple cutters 5 when the cutter disc 4 rotates relative to the cutter cylinder 3.

[0043] In this embodiment, since the high-fiber material entering the crushing chamber from the inlet 1a is relatively large in size, while the high-fiber material being sheared during the downward movement is relatively small in size, the cutter disc 4 is eccentrically positioned as shown above. This results in a greater overlap between the two sets of cutters 5 when the cutter 5 rotates to the upper part, and a smaller overlap between the two sets of cutters 5 when the cutter 5 rotates to the lower part. This effectively utilizes the rotational driving force to improve the shearing capacity of the material in the upper part.

[0044] In one embodiment, the shredder also includes a jet nozzle 6, which is disposed in the shredding chamber 1 and connected to an external air source, and is used to spray airflow toward the cutter 5.

[0045] In this embodiment, high-pressure airflow can be sprayed onto the cutter 5 through the jet nozzle 6 to effectively remove debris adhering to the cutter 5 and ensure the shearing capacity of the cutter 5. At the same time, the high-pressure airflow can also agitate the material in the crushing chamber 1, further improving the homogenization capacity.

[0046] It should be noted that, in one embodiment, the nozzle 6 is equipped with a one-way valve, which allows the nozzle 6 to only expel air and not return material, thus preventing the nozzle 6 from becoming clogged. Its specific structure and principle are existing technology and will not be elaborated upon here.

[0047] In one embodiment, the cutter 5 includes a blade with cutting edges on both sides of the cutter disc 4 in the direction of rotation relative to the cutter cylinder 3.

[0048] In this embodiment, blades are provided on both sides of the rotating direction of the cutter 5, allowing for flexible adjustment of the relative rotation direction of the blade cylinder 3 and the cutter disc 4, thus improving practicality. It should be noted that in one embodiment, the blades are arranged in a herringbone shape, with the blade angle optimized by hydrodynamics, enabling efficient gripping and cutting of various high-fiber materials.

[0049] It should be noted that, in one embodiment, the mounting shafts of the toothed roller 2 and the cutter disc 4 can be extended outside the crushing chamber 1 and driven by human or wind power. Alternatively, the relative rotation of the toothed roller 2 and the cutter disc 4 can be achieved through other means.

[0050] In one embodiment, the pulverizer further includes a drive unit 7, which is installed in the pulverizing chamber 1 and connected to at least one toothed roller 2 for driving two toothed rollers 2 to rotate relative to each other, and is connected to at least one of the cutter disc 4 and the cutter cylinder 3 for driving the cutter disc 4 to rotate relative to the cutter cylinder 3 about its own axis.

[0051] In this embodiment, the drive unit 7 drives the toothed roller 2 and the cutter head 4 to rotate, facilitating automation. It should be noted that rotation can be achieved directly by a rotary motor, or through the cooperation of a hydraulic rod, an electric actuator, and a connecting rod. Specifically, in this solution, the drive unit 7 is equipped with a first motor, a second motor, and a third motor, with corresponding transmission gears, independently driving the toothed roller 2, the cutter cylinder 3, and the cutter head 4 to rotate. The specific structure and transmission principle are existing technologies and will not be elaborated upon here.

[0052] In one embodiment, the crusher also includes a torque sensor located on the toothed roller 2 for monitoring the torque of the toothed roller 2.

[0053] In this embodiment, when the torque sensor detects that the torque of the toothed roller 2 reaches a threshold, it determines that the load on the toothed roller 2 is abnormal. At this time, the machine needs to be stopped for maintenance to avoid damaging the toothed roller 2. It should be noted that the specific structure and principle of the torque sensor are existing technologies and will not be described in detail here.

[0054] In one embodiment, please refer to Figure 4 and Figure 5 The toothed roller 2 includes a roller shaft 21 and a plurality of crushing teeth 22. The roller shaft 21 is rotatably installed in the crushing chamber 1. The plurality of crushing teeth 22 are installed on the roller shaft 21 and are arranged at intervals along the axial direction of the roller shaft 21, and a gap 22a is formed between two adjacent crushing teeth 22. The crusher also includes a hook knife 8, which is installed in the crushing chamber 1 and has a hook section 81 that extends into the gap 22a. The hook section 81 is arranged in a semi-arc shape and its arc-shaped opening faces the roller shaft 21.

[0055] In this embodiment, on the one hand, the hook blade 8 can directly hook away the high-fiber waste wrapped around the roller 21; on the other hand, the hook blade 8 can also form a shearing action with the crushing teeth 22, gradually cutting and peeling off the remaining fibrous material, effectively preventing the fiber material from wrapping around the toothed roller 2. Specifically, the hook blade 8 is integrally cast from high-manganese steel. Multiple hook blades 8 are set for multiple crushing teeth 22, and the axial distance between the hook blade 8 and the adjacent crushing teeth 22 is designed to be 8-12 mm according to the characteristics of common fibrous waste.

[0056] It should be noted that, in one embodiment, the crushing tooth 22 is made of SKD-11 (high carbon high chromium alloy tool steel) alloy steel, and the material is uniformly crushed to an ideal particle size of 5-8 mm by a variable frequency speed of 25-35 rpm, creating conditions for subsequent processing.

[0057] In one embodiment, the hook blade 8 can rotate relative to the crushing chamber 1 and adjust the angle between the hook section 81 and the horizontal direction during rotation; the crushing chamber 1 also includes an adjustment part, which is installed in the crushing chamber 1 and connected to the hook blade 8, for driving the hook blade 8 to rotate relative to the crushing chamber 1.

[0058] In this embodiment, it should be understood that the thickness direction of the hook blade 8 is the same as the axial direction of the crushing tooth 22, and the angle between the hook blade 8 and the horizontal direction is adjustable. This allows the angle between the hook blade 8 and the horizontal direction to be adjusted according to the characteristics of different types of waste, ensuring optimal stripping performance.

[0059] Specifically, in one embodiment, the hook blade 8 is adjusted in 5° increments, with the reference 0° position corresponding to the center line of the comb teeth and the vertical line of the blade axis. By analyzing the entanglement force and debris composition using multi-dimensional force sensors and near-infrared spectroscopy, the optimal angle is predicted based on a BP neural network (backpropagation neural network). The installation angle of the comb teeth is precisely adjusted within a 15° range according to different debris characteristics through a hydraulic servo system, ensuring the best stripping effect.

[0060] It should be noted that the hook knife 8 can be driven to rotate directly by a motor, or it can be rotated through the cooperation of an electric actuator, a hydraulic rod, and gears and racks.

[0061] In one embodiment, the adjustment unit includes a mounting base 9, a rotating shaft, and an adjustment motor (not shown). The mounting base 9 is connected to the rotating shaft and is rotatably mounted in the crushing chamber 1 via the rotating shaft. The rotating shaft extends out of the crushing chamber 1. The output shaft of the adjustment motor is connected to the rotating shaft and drives the rotating shaft to rotate. The hook blade 8 is detachably mounted on the mounting base 9.

[0062] In this embodiment, the mounting base 9 is directly driven to rotate by a motor, which in turn drives the hook blade 8 to rotate. The motor is placed outside the crushing chamber 1, extending its service life and facilitating replacement and maintenance. Simultaneously, the hook blade 8 is detachably connected to the mounting base 9 for easy replacement.

[0063] It should be noted that the hook blade 8 and the mounting base 9 can be detachably connected by bolts, pins, or clips. Specifically, in one embodiment, the hook blade 8 and the mounting base 9 are detachably connected by bolts and threaded holes.

[0064] In addition, in one embodiment, an infrared detection unit is provided at the inlet 1a, which can perform preliminary analysis of the waste composition. Its specific structure and working principle are existing technologies and will not be described in detail here.

[0065] Furthermore, this utility model also provides a food waste treatment system, which includes the shredder described above. It should be noted that the detailed structure of the shredder in the food waste treatment system can be found in the embodiments of the shredder described above, and will not be repeated here. Since the shredder described above is used in the food waste treatment system of this utility model, the embodiments of the food waste treatment system of this utility model include all the technical solutions of all the embodiments of the shredder described above, and the achieved technical effects are also completely the same, and will not be repeated here.

[0066] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0067] In this design, the relative rotation of the cutter disc 4 and the cutter cylinder 3 allows for the cyclic shearing of high-fiber materials entering the grinding chamber 1, reducing the size of the high-fiber materials and preventing them from entangled on the toothed roller 2. Furthermore, the relative rotation of the cutter disc 4 agitates the kitchen waste within the grinding chamber 1, facilitating homogenization.

[0068] The system employs a dual-shaft shredding toothed roller 2 with precision blades. When wet waste enters the crushing chamber, two rollers 21, rotating in opposite directions at a variable frequency speed of 25-35 rpm, drive specially designed SKD-11 alloy steel crushing teeth 22. These crushing teeth 22 utilize a spiral multi-tooth layout and an interlocking structure, precisely adjusting the gap 22a by 5-10 mm to perform multi-stage shearing and compression on the material. The material first undergoes a primary crushing stage to break down large pieces of waste, then is further processed to the target particle size in a fine crushing stage, and finally passes through a screen to ensure uniform and compliant particle size distribution. Furthermore, when the torque sensor detects an abnormal load on the toothed roller 2, the hook blade 8 can promptly remove high-fiber entangled materials.

[0069] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
