Description

Technical Field

[0001] This utility model relates to the field of food waste separation technology, and in particular to an easy-to-install and maintain spindle and a food waste separator containing the spindle. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] The 2D materials in municipal solid waste mainly consist of plastic film materials such as PE and PP bags. Conventional treatment involves separating these from the 3D materials in the waste, then washing the 2D materials with water to remove surface residues, dust, and other impurities. This improves the purity and value of the recycled plastics and avoids affecting subsequent processing. A typical kitchen waste separator combines mechanical separation with hydraulic washing. First, the waste is crushed and broken up, tearing apart large pieces and releasing the film material from adhesion to other components. Then, a screen is used to separate small particles of impurities, while water is used to wash the screen. The detached impurities pass through the screen holes and are collected at the bottom before being output. The clean film material remains inside the screen and is output at the end for subsequent sorting stages.

[0004] The prior art discloses a pre-washing machine, as disclosed in invention patent application CN106733865A. This machine includes a casing, with a material chamber inside. One end of the material chamber has a feed inlet, the other end has a discharge outlet, and the bottom of the material chamber has a mud / sand outlet. A main shaft is pivotally connected to the material chamber, with one end forming a feeding end and the other end forming a cleaning end. The feeding end has a feeding trough, which is spirally distributed on its outer surface. The cleaning end has a cleaning trough, which is spirally distributed on its outer surface. The pitch of the cleaning trough is greater than that of the feeding trough. One end of the feeding trough is connected to the feed inlet, and the other end is connected to one end of the cleaning trough and the other end of the cleaning trough is connected to the discharge outlet. The mud / sand outlet is located below the cleaning end. A drive mechanism is used to drive the main shaft to rotate. However, the aforementioned technical solutions and related technologies still have many problems, such as: ① Using a single through-shaft requires a long... The long shaft is machined using precision machine tools to ensure straightness, roundness, and coaxiality throughout its entire length. This requires high precision and is costly. Precisely installing the long shaft into the bearing housings at both ends requires precise alignment and coaxiality. Even slight misalignment can lead to additional loads on the bearings, overheating, increased wear, and increased vibration. Therefore, assembly precision is crucial and assembly is challenging. Furthermore, the long shaft itself is expensive to produce, and precision machining is even more costly. Replacing a bearing or shaft requires disassembling the entire shaft along with the container, resulting in significant work. If the shaft is damaged, the entire shaft must be replaced, leading to high replacement costs. Secondly, the impurities separated by the food waste separator often contain thin, soft, long ropes. While screw conveyors are commonly used for output, they are prone to tangling with ropes, causing the shaft to seize. Additionally, if the impurities contain wires or hard materials, they can easily get stuck in the shaft gaps, causing the conveyor shaft to jam and become damaged. Utility Model Content

[0005] The purpose of this utility model is to provide an easy-to-install and maintain spindle to solve the technical problems commonly found in the spindles of food waste separators, such as high machining accuracy requirements, difficult installation and maintenance, and the tendency for the spindle to jam due to sludge rotation during waste output.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-install and maintain spindle includes:

[0008] The shaft body is configured as a hollow cylindrical structure, and the outer side of the shaft body is provided with blades extending along the axial direction;

[0009] The shaft head includes a left shaft head and a right shaft head arranged coaxially, and the left shaft head and the right shaft head are respectively fixedly installed relative to the two sides of the shaft body through an inner ring plate and an outer ring plate.

[0010] Furthermore, both the left and right shaft heads include a coaxial connecting part and a fixing part. The connecting part is used for rotatable installation with the bearing seat. The fixing part has an outer shaft shoulder and an inner shaft shoulder at both ends. The size of the outer shaft shoulder and the inner shaft shoulder is smaller than the diameter of the fixing part. An outer ring plate is fitted on the outer shaft shoulder, and an inner ring plate is fitted on the inner shaft shoulder.

[0011] Furthermore, both the inner and outer ring plates are welded to the inner wall of the shaft body, and both the left and right shaft ends are welded to the outer and inner ring plates.

[0012] Furthermore, the length of the shaft is L, the distance between the inner ring plate of the left shaft head and the left end face of the shaft is L1, the distance between the inner ring plate of the right shaft head and the right end face of the shaft is L2, and the diameter of the shaft is D, where: L1=L2, 6L1<L<8L2, 4D<L<7D.

[0013] A food waste separator with an easily installable and maintainable main shaft includes a frame and a housing mounted on the frame. Bearing seats are fixedly mounted at both ends of the housing and rotatably mounted on the shaft ends of the main shaft. The main shaft is driven to rotate by a transmission unit via a belt cover assembly. The main shaft extends through the interior of the housing, and a screen is also installed inside the housing, fitted onto the outside of the main shaft. The screen divides the interior of the housing into a slag discharge chamber and a material chamber. A slag receiving hopper is located at the bottom of the housing below the slag discharge chamber, and this slag receiving hopper is connected to the inlet of a scraper feeding mechanism. One end of the material chamber is connected to a feed inlet, and the other end is connected to a discharge hopper. A discharge outlet is located at the bottom of the discharge hopper. The feed inlet is also equipped with a water inlet. The scraper feeding mechanism is used to transport impurities discharged from the slag receiving hopper to the slag discharge outlet.

[0014] Furthermore, the scraper feeding mechanism includes a cover, which is L-shaped. One end of the cover is located at the bottom of the slag receiving hopper and has an inlet communicating with the slag receiving hopper. The other end of the cover has a slag outlet. A rotating chain assembly is installed inside the cover. The chain assembly is driven to rotate by sprockets at both ends. The sprockets are rotatably mounted on the cover. The sprockets are driven to rotate by the slag discharge sprocket cover assembly. A scraper is installed on the chain assembly for scraping and pushing the impurities discharged from the slag receiving hopper and falling into the cover.

[0015] Furthermore, a water inlet is provided on the side of the cover near the inlet, and a water outlet is provided at the lowest point of the horizontal section of the cover away from the water inlet.

[0016] Furthermore, a limiting plate is provided inside the housing. The limiting plate is installed on the two inner side walls of the housing, and there are limiting channels between the limiting plate and the top and bottom walls of the housing. These limiting channels are used for the sliding operation of the chain assembly.

[0017] Furthermore, the chains of the chain assembly are hinged together by a wheel, which rolls within a limiting channel when the chain assembly is running.

[0018] Furthermore, the bottom of the cover near the water inlet is provided with an inclined plate, the two sides of which are connected to the two side walls of the cover, the top edge of which is connected to the end side of the cover, and the bottom edge of which is connected to the bottom surface of the cover.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] (1). This utility model abandons the traditional single through-shaft structure by setting the main shaft to a structure in which the two side shaft heads cooperate with the central shaft body. It adopts a combination of two side shaft heads and ring plates, which not only reduces the processing difficulty and processing cost, but also avoids the high processing precision and high processing cost required for a single through-shaft. It also avoids vibration and wear caused by changes in coaxiality due to easy deformation of the long shaft during use, thereby reducing the failure rate. By limiting the shaft body length, shaft body diameter and the distance range between the ring plate and the shaft body end face, it can better avoid the reduction in rigidity and bending resistance caused by replacing the long shaft with two side shaft heads. At the same time, combined with the setting of blades, it is beneficial to simultaneously take into account the ease of installation and maintenance as well as the performance requirements of main shaft rigidity and strength.

[0021] (2). This utility model improves space utilization by setting up a scraper feeding mechanism. The L-shaped design is conducive to adapting to the slag receiving hopper at the bottom of the kitchen waste separator. At the same time, the chain assembly works in conjunction with the scraper to scrape and push the waste residue and impurities, avoiding the phenomenon that long and thin impurities tend to wrap around the shaft and cause the screw to jam, which is common in traditional screw conveying. This reduces the failure rate. By setting up water inlet and outlet, it is beneficial to regularly flush the residual impurities in the casing and prevent long-term siltation that increases the difficulty of cleaning. By setting up inclined plate, it is beneficial to avoid dead corners where impurities accumulate near the water inlet of the casing. Attached Figure Description

[0038] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0039] This utility model primarily addresses common problems in existing food waste separators, such as the high precision requirements for the single 601 main shaft, resulting in high processing difficulty, high processing costs, and high installation and maintenance difficulties. Furthermore, the waste residue and impurities screened out by the food waste separator easily become entangled in the rotating shaft during transport, causing it to jam and seize, thus affecting the overall working efficiency and installation and maintenance costs of the food waste separator. To overcome these problems, this utility model incorporates the following technical optimizations and improvements:

[0040] See appendix Figure 1 and attached Figure 2A main shaft 601 that is easy to install and maintain is used in a food waste separator to clean and screen plastic materials during rotation. The main shaft 601 includes: a shaft body 6013, which is a hollow cylindrical structure with axially extending blades 6019 on its outer side. The blades 6019 are conventionally chosen in the prior art, with the main rule being that the blades 6019 extend along the axial direction of the shaft body 6013. Furthermore, the blades 6019 are helical blades 6019 to facilitate forward material pushing; and shaft heads, including a coaxially arranged left shaft head 6011 and a right shaft head 6012, each fixedly mounted to the sides of the shaft body 6013 via an inner ring plate 6015 and an outer ring plate 6014. Specifically, both the left shaft head 6011 and the right shaft head 6012 include a coaxial connecting portion 6016 and a fixing portion 6020. Both the connecting portion 6016 and the fixing portion 6020 are cylindrical. The diameter of the connecting portion 6016 is smaller than the diameter of the fixing portion 6020. The connecting portion 6016 is rotatably mounted to the bearing housing. The fixing portion 6020 has an outer shaft shoulder 6017 and an inner shaft shoulder 6018 at both ends. The dimensions of both the outer shaft shoulder 6017 and the inner shaft shoulder 6018 are smaller than the diameter of the fixing portion 6020. An outer ring plate 6014 is fitted onto the outer shaft shoulder 6017, and an inner ring plate 6015 is fitted onto the inner shaft shoulder 6018. Both the inner ring plate 6015 and the outer ring plate 6014 are welded to the inner wall of the shaft body 6013. Both the left shaft head 6011 and the right shaft head 6012 are welded to the outer ring plate 6014 and the inner ring plate 6015. It is evident here that the left shaft head 6011 and the right shaft head 6012 are respectively installed at both ends of the shaft body 6013, and the connecting portions 6016 of both the left shaft head 6011 and the right shaft head 6012 are located on the outside of the shaft body 6013 for rotatable installation with the bearing housing. Both the left shaft head 6011 and the right shaft head 6012 are equipped with an outer ring plate 6014 and an inner ring plate 6015. The inner ring plate 6015 is located at the end of the fixing portion 6020 away from the connecting portion 6016, and the outer ring plate 6014 is located at the end of the fixing portion 6020 closer to the connecting portion 6016. The outer circumferential surfaces of both the inner ring plate 6015 and the outer ring plate 6014 are fitted with the inner wall of the shaft body 6013 and then welded for fixed installation. The outer shaft shoulder 6017 and the inner shaft shoulder 6018 facilitate axial positioning of the inner ring plate 6015 and the outer ring plate 6014, thereby improving installation stability. The length of the shaft 6013 is L, the distance between the inner ring plate 6015 of the left shaft head 6011 and the left end face of the shaft 6013 is L1, the distance between the inner ring plate 6015 of the right shaft head 6012 and the right end face of the shaft 6013 is L2, and the diameter of the shaft 6013 is D, where: L1=L2, 6L1<L<8L2, 4D<L<7D. The purpose of limiting the dimensions of each part here is to improve the connection strength between the two ends of the shaft 6013 and the shaft head, and at the same time, in combination with the blade 6019, to improve the overall rigidity of the main shaft 601.

[0041] See appendix Figure 3-9 A food waste separator including the aforementioned easy-to-install and maintain main shaft 601 includes a frame 100 and a housing 200 mounted on the frame 100. Bearing seats are fixedly mounted at both ends of the housing 200 and rotatably mounted on the shaft ends of the main shaft 601. The main shaft 601 is driven to rotate by a transmission unit 300 via a belt cover assembly 500. Here, the transmission unit 300 is a motor. The belt cover assembly 500 includes a drive pulley that rotates synchronously with the motor main shaft 601 and a driven pulley connected to the drive pulley via a belt. The driven pulley is rotatably mounted synchronously with the right shaft end 6012. The right shaft end 6012 is rotatably mounted between itself and the right bearing seat 603 on the housing 200. The left shaft end 6011 is rotatably mounted between itself and the left bearing seat 602 on the housing 200. The main shaft 601 penetrates the interior of the housing 200, and the interior of the housing 200... The unit also has a screen 604 installed on the outside of the main shaft 601. The screen 604 divides the inside of the machine housing 200 into a slag discharge chamber and a material chamber 605. It can be understood that the screen 604 is fitted on the outer ring of the main shaft 601 and there is a cavity between the screen 604 and the main shaft 601. This cavity is the material chamber 605, while the cavity between the screen 604 and the inner wall of the machine housing 200 is the slag discharge chamber. The bottom of the machine housing 200 is provided with a slag receiving hopper 101 below the slag discharge chamber. The slag receiving hopper 101 is connected to the inlet of the scraper feeding mechanism 400. One end of the material chamber 605 is connected to the feed inlet 202, and the other end is connected to the discharge bin 205. The bottom of the discharge bin 205 is provided with a discharge outlet 201. The feed inlet 202 is also provided with a water inlet 203. The scraper feeding mechanism 400 is used to transport the impurities discharged from the slag receiving hopper 101 to the slag discharge outlet 403. It can be understood here that the main shaft 601 passes through the housing 200 and its two ends are connected to the feed inlet 202 and the discharge bin 205, respectively. That is, after the material enters through the feed inlet 202, it is rotated and conveyed by the main shaft 601 to the material chamber 605 inside the housing 200, which is the cavity between the main shaft 601 and the screen 604. At the same time, water enters through the water inlet 203 to wash the material. Waste residue and impurities enter the slag receiving hopper 101 through the screen 604. The screened material is then conveyed through the main shaft 601 to the discharge bin 205 and discharged through the discharge outlet 201.

[0042] See appendix Figure 7-9The scraper feeding mechanism 400 includes a cover 401, which is a rectangular cover formed by surrounding plates. The cover 401 is L-shaped with an obtuse angle. The horizontal part of the L-shape is located below the slag receiving hopper 101, and the other side extends obliquely upward. One end of the cover 401 is located at the bottom of the slag receiving hopper 101 and has an inlet communicating with the slag receiving hopper 101. The other end of the cover 401 has a slag outlet 403. A rotating chain assembly 405 is installed inside the cover 401. The chain assembly 405 is a relatively conventional technology in the prior art and will not be described in detail here. The two ends of the chain assembly 405 are driven to rotate through sprockets. The sprocket is rotatably mounted on the cover 401. Specifically, both ends of the sprocket are rotatably mounted on the side wall of the cover 401. The sprocket is driven to rotate by the slag discharge sprocket cover assembly 404, which includes a motor and a driving sprocket and a driven sprocket driven by the motor. The driving sprocket is located at a high position, and the driven sprocket is located at a low position. A scraper 406 is installed on the chain assembly 405 to scrape and push the impurities discharged from the slag receiving hopper 101 into the cover 401. The position of the scraper 406 can be adjusted by using the elongated hole on the mounting plate between the scraper 406 and the chain. A water inlet 204 is also provided on the side of the cover 401 near the inlet. It should be noted that the water inlet 204 is located on the rear vertical surface of the cover 401 near the inlet. A water outlet 408 is provided at the lowest point of the horizontal section of the cover 401 away from the water inlet 204. A limiting plate 407 is provided inside the housing 401. The limiting plate 407 is installed on the two inner side walls of the housing 401, and limiting channels exist between the limiting plate 407 and the top and bottom walls of the housing 401. These limiting channels are used for the sliding operation of the chain assembly 405. It is understood that the limiting plate 407 is made of sheet metal. The limiting plate 407 is installed on the side walls of the housing 401, and gaps are left between the top and bottom of the limiting plate 407 and the top and side walls of the housing 401. These gaps provide guidance for the rotational operation of the chain assembly 405. The chains of the chain assembly 405 are hinged together by rollers. When the chain assembly 405 is running, the rollers roll within the limiting channels. It is understood that the rollers can be bearings or other wheel-like structures. The bottom of the cover 401 near the water inlet 204 is provided with an inclined plate 402. The two sides of the inclined plate 402 are connected to the two side walls of the cover 401, the top edge of the inclined plate 402 is connected to the end side of the cover 401, and the bottom edge of the inclined plate 402 is connected to the bottom surface of the cover 401. It can be understood that the setting of the inclined plate 402 helps to avoid dead corners inside the cover 401 and reduce the difficulty of subsequent cleaning.

[0043] When using this invention to clean and screen 2D materials, the material is fed in through the feed inlet 202 and water is simultaneously introduced through the water inlet 203. The material is conveyed axially along the main shaft 601 and cleaned by water. The cleaned material enters the discharge bin 205 along the main shaft 601. The cleaned waste residue and impurities pass through the screen 604 and enter the slag receiving hopper 101, then enter the scraper feeding mechanism 400. When the scraper feeding mechanism 400 operates, the chain assembly 405 rotates, driving the scraper 406 to move along the inner wall of the cover 401, scraping and pushing the waste residue and impurities falling into the cover 401 to the slag outlet 403 for discharge.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
