Description

Technical Field

[0001] The utility model relates to the technical field of belt cleaning equipment, in particular to a belt cleaning device for transporting anaerobic fermentation materials. Background Art

[0002] Dry anaerobic fermentation technology is a method for generating clean energy from waste. During the fermentation process, the material typically contains a high proportion of solids, typically exceeding 20%. This solid matter, combined with the moisture in the material, makes it easy for the solids to adhere to each other. Consequently, the dry anaerobic fermentation material has a high adhesiveness, making it prone to clumping and sticking to the belt during transportation. This phenomenon makes it difficult to clean the belt, increasing cleaning costs and causing uneven pressure distribution on the conveyor belt, thus shortening its service life.

[0003] Traditional cleaning methods usually rely on conventional brushes or scrapers. Although these tools can remove materials to a certain extent, they are less effective when dealing with highly adhesive materials. As a result, these materials adhering to the belt will gradually aggregate into lumps during continuous production, further increasing the difficulty of cleaning and shortening the service life of the belt.

[0004] Therefore, this solution provides an anaerobic fermentation material transport belt cleaning device that combines the dual cleaning methods of "high-pressure nozzle + brush". This device not only greatly improves the cleaning efficiency, but also ensures the thoroughness of cleaning, effectively reduces the residue on the belt surface, and achieves a cleaning effect of no dead angle cleaning of the belt. Utility Model Content

[0005] The utility model aims to provide an anaerobic fermentation material transport belt cleaning device, which effectively solves the technical problem of poor belt cleaning effect in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: it includes a belt cleaning mechanism installed on a material transport mechanism, the material transport mechanism includes a transport belt conveyor, the transport belt conveyor is provided with a rolling and flipping belt, the discharge end of the transport belt conveyor is provided with a discharge bin, and side panels are provided on both sides of the discharge bin; the belt cleaning mechanism includes a waist-shaped hole provided on each side panel, and a high-pressure air pump connected through the waist-shaped hole on one side; the belt cleaning mechanism also includes a cavity, the cavity is installed between the waist-shaped holes, and the top of the cavity is provided with a high-pressure nozzle for cleaning the belt, and the high-pressure nozzle is located below the transport belt conveyor and aligned with the belt; the discharge bin is provided with a brush for cleaning the belt on the side close to the transport belt conveyor, and the brush is located below the transport belt conveyor and in direct contact with the belt.

[0007] The principle of this solution is as follows: a conveyor belt conveyor is used to transport anaerobic fermentation materials, allowing them to be smoothly conveyed from the feed end to the discharge end, where they fall into a discharge hopper. The discharge hopper is flanked by side panels, each with a corresponding waist-shaped hole. The waist-shaped holes are used to adjust the vertical position of the belt cleaning mechanism to accommodate belts of varying heights and different cleaning requirements, ensuring optimal contact between the belt cleaning mechanism and the belt surface, thereby improving cleaning efficiency. A high-pressure air pump is connected to one of the waist-shaped holes on one side of the belt to supply high-pressure air to the chamber. This high-pressure air flows into the chamber and then directly sprays onto the belt through a high-pressure nozzle. The high-pressure air pump provides stable high-pressure air and powerful airflow to effectively remove materials adhering to the belt surface, evenly spraying into hard-to-reach corners and crevices, thereby improving cleaning efficiency. After being treated by the high-pressure nozzle, the belt is again cleaned by a brush. The brush uses physical friction to further remove small particles and residue from the belt surface, ensuring a cleaner surface. The brush also ensures uniform contact with small gaps on the belt surface, ensuring consistent treatment of every area and avoiding uneven cleaning.

[0008] The advantages of this solution are:

[0009] 1. Compared to existing technologies, which offer poor belt cleaning results, this solution utilizes a dual cleaning method: a "high-pressure nozzle + brush." ​​The high-pressure air jet and brush work synergistically, working together to clean the belt thoroughly and without blind spots. The high-pressure nozzle provides a powerful impact to remove large amounts of material adhering to the belt and remove hard-to-reach corners, while the brush meticulously penetrates the tiny gaps on the belt surface to remove any remaining particles, ensuring a cleaner belt surface. This dual cleaning method not only improves cleaning efficiency but also ensures thoroughness, reducing residue on the belt surface and increasing belt cleanliness and service life.

[0010] 2. The waist-shaped hole is used to adjust the upper and lower positions of the belt cleaning mechanism, which can adapt to belts of different heights and different cleaning requirements, ensuring that the belt cleaning mechanism always maintains optimal contact with the belt surface and improves the cleaning effect.

[0011] 3. The high-pressure air pump is used to provide high-pressure gas to the cavity, and the high-pressure gas is directly sprayed onto the belt through the high-pressure nozzle to clean the belt surface. The high-pressure air pump can provide stable high-pressure gas to ensure that the high-pressure nozzle can generate sufficient airflow, thereby efficiently removing residual materials on the belt.

[0012] 4. The high-pressure nozzle is installed below the conveyor belt and aimed at the belt's swiveling position (i.e., when not transporting material). It uses a bottom-up cleaning method that sprays high-pressure gas. This method allows the high-pressure gas to directly impact residual material on the belt surface, effectively cleaning it. At the same time, the bottom-up spraying method allows the blown-off material to fall directly into the discharge hopper below, preventing material from splashing and rebounding to other parts, reducing secondary contamination. The positioning of the high-pressure nozzle does not interfere with the belt's function of forward transporting materials. While materials are being transported normally, the belt can be continuously cleaned and maintained. This synchronous cleaning method not only improves production efficiency but also ensures the cleanliness of the belt and its carried materials.

[0013] 5. The brush is installed under the conveyor belt and is in direct contact with the belt. After the belt is initially cleaned by the high-pressure nozzle, the brush performs a detailed secondary cleaning, that is, the soft bristles of the brush penetrate into the tiny gaps on the belt surface to achieve a more detailed cleaning effect. The brush is located at the rotation position of the belt, that is, the position where the belt is in a non-working state (the belt is not transporting materials). This allows for a comprehensive and thorough cleaning of the belt without affecting the forward transportation of materials.

[0014] 6. The design of the brush and high-pressure nozzle position ensures that the belt will not affect the forward transportation of materials during the cleaning process, ensuring the cleaning effect while taking into account production efficiency.

[0015] Preferably, as an improvement, connecting pipes are provided on both sides of the cavity, and the outer surfaces of the connecting pipes are provided with threads. The connecting pipes pass through the waist-shaped holes and cooperate with nuts to fix the cavity between the two waist-shaped holes.

[0016] Beneficial effects: The cavity is located between the two waist-shaped holes. By adjusting the position of the connecting pipe and the nut, the position of the cavity and the spray angle and direction of the high-pressure nozzle can be flexibly adjusted, so that the belt cleaning mechanism can adapt to belts of different widths and different working environments, thereby improving the flexibility and adaptability of the device. At the same time, the nut is matched to make its installation and disassembly easy. Just rotate the nut to easily disassemble and install the device, which is convenient for later maintenance and inspection.

[0017] Preferably, as an improvement, the belt cleaning mechanism further includes a high-pressure air pipe, a gas channel is provided inside the cavity, the high-pressure air pipe is connected to the gas channel and the high-pressure nozzle through a connecting pipe, and the high-pressure air pipe is connected to the high-pressure air pump.

[0018] Beneficial Effects: The design of the gas channel and connecting pipe ensures stable transportation of high-pressure gas from the high-pressure air pump to the high-pressure nozzle, ensuring the continuity and stability of the high-pressure gas. The gas channel reduces pressure loss during high-pressure gas transmission, allowing the high-pressure nozzle to obtain sufficient air pressure, improving cleaning effectiveness. In addition, it ensures uniform distribution of high-pressure gas at the high-pressure nozzle, avoiding localized over- or under-intensity of the spray, thereby improving the overall cleaning effect.

[0019] Preferably, as an improvement, a scraper for cleaning the cavity is provided on the discharge bin, the scraper is parallel to the cavity and is located at the bottom of the cavity, and is in direct contact with the surface of the cavity.

[0020] Beneficial Effects: The direct contact between the scraper and the cavity surface effectively scrapes away any material adhering to the cavity surface, ensuring that no material remains on the cavity. By adjusting the connecting tube and nut, the cavity can rotate, allowing the scraper to continuously clean the cavity surface, preventing material from accumulating on the cavity and thus avoiding the problem of incomplete cleaning caused by material accumulation.

[0021] Preferably, as an improvement, the scraper is provided with a flexible brush.

[0022] Beneficial effects: The soft nature of the flexible brush can reduce wear and scratches on the cavity surface, extend the service life of the cavity, and the flexible brush can better fit the curved surface of the cavity, ensuring that every corner can be thoroughly cleaned, achieving a more comprehensive cleaning effect.

[0023] Preferably, as an improvement, the shape of the waist-shaped hole is elliptical, and the height of the waist-shaped hole ranges from 1 cm to 5 cm.

[0024] Beneficial effects: The adjustment range of 1 cm to 5 cm allows the upper and lower positions of the belt cleaning mechanism to be flexibly adjusted to adapt to belts of different heights and different working environments, thereby improving the flexibility and adaptability of the device, ensuring that the belt cleaning mechanism can be accurately aligned and improving the cleaning effect.

[0025] Preferably, as an improvement, the nut is a fastening nut, and the fastening nut includes a right-end fastening nut 1, a right-end fastening nut 2, a left-end fastening nut 1 and a left-end fastening nut 2.

[0026] Beneficial effects: Two fastening nuts are used at both ends of the connecting pipe. The double-nut locking method can effectively prevent the loosening of the belt cleaning mechanism caused by vibration or external force, which can improve the reliability of the connection. In addition, each fastening nut can be adjusted independently, and the position and tightness of each part can be adjusted more flexibly during installation or maintenance. It is also easy to disassemble.

[0027] Preferably, as an improvement, the rotation angle of the high-pressure nozzle is 0 degrees to 360 degrees.

[0028] Beneficial effects: The high-pressure nozzle can rotate within the range of 0 to 360 degrees, allowing it to cover every corner of the belt, including hard-to-reach areas. At the same time, the angle of the high-pressure nozzle can be flexibly adjusted according to the characteristics of different materials to achieve the best cleaning effect.

[0029] Preferably, as an improvement, the number of the high-pressure nozzles is 4-8.

[0030] Beneficial effect: The synergistic effect of multiple high-pressure nozzles can shorten the cleaning time and improve production efficiency. At the same time, they can be flexibly arranged according to the actual width of the belt to ensure that the nozzle's spray range can completely cover the belt surface.

[0031] Preferably, as an improvement, a bracket for supporting is provided at the bottom of the conveyor belt conveyor.

[0032] Beneficial effect: The bracket can better distribute the weight, reduce the risk of tipping due to unstable center of gravity, and improve the stability of the entire device.

[0033] Beneficial effects of the present utility model: This solution constructs a highly flexible and efficient anaerobic fermentation material conveying belt cleaning device through a series of carefully designed components - including a conveyor belt conveyor, a bracket, a waist-shaped hole, a high-pressure air pump, a cavity, a high-pressure nozzle, a brush, a scraper, a connecting pipe and a nut. The device can arbitrarily adjust the rotation angle of the high-pressure nozzle and the up and down, left and right positions of the belt cleaning structure, thereby performing a "high-pressure nozzle + brush" dual cleaning method to ensure full coverage and thorough cleaning of every corner of the belt surface. Compared with traditional cleaning methods such as brushes and scrapers, this solution is more flexible and can cope with various complex working environments and cleaning needs; at the same time, it can also adjust the pressure, position and angle of the high-pressure nozzle according to the ambient temperature and the agglomeration of the material, and cooperate with the brush cleaning to ensure the best cleaning effect under different conditions, thereby improving the adaptability and practicality of the device. Specifically, the position of the belt cleaning mechanism is fixed and adjusted by adjusting the waist-shaped hole, connecting pipe and nut, so that it can adapt to belts of different heights and different cleaning needs, ensuring that the belt cleaning mechanism always maintains optimal contact with the belt surface and improves the cleaning effect. In addition, the cavity can also be cleaned, and the scraper is used to clean the material attached to the cavity surface to prevent the material from accumulating on the cavity, thereby avoiding the problem of incomplete cleaning due to material accumulation.

[0034] In this solution, the synergistic effect between "high-pressure nozzle + brush" significantly improves the cleaning effect of the belt. The high-pressure nozzle uses a strong airflow to blow away the residual material on the belt, and the brush that follows performs secondary cleaning to ensure that the belt treated by the high-pressure nozzle can be more thoroughly cleaned. This combination of physical removal (brush) and aerodynamic removal (high-pressure nozzle) not only improves the cleaning efficiency, but also ensures the thoroughness of the cleaning process. At the same time, the high-pressure nozzle sprays high-pressure gas from the bottom to the top, directly impacting the residual material on the surface of the belt, blowing these materials off and directly sending them into the discharge bin below. However, during the spraying process, a small amount of material will adhere to the cavity. At this time, a scraper is used to clean the material adhering to the surface of the cavity to ensure the cleanliness of the cavity surface.

[0035] This solution utilizes a highly flexible and efficient cleaning device that significantly improves belt and cavity cleaning, ensuring smooth material conveying and long-term equipment reliability. The device is also easy to install and remove; simply by turning a nut, the belt cleaning mechanism can be removed and installed, eliminating the need for complex tools or specialized technicians. This significantly reduces operating costs and improves overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following is further described in detail through specific implementation methods:

[0043] The figure marks in the drawings of the specification include: conveyor belt 1, high-pressure air pump 2, waist-shaped hole 3, high-pressure air pipe 4, right-end fastening nut one 5, right-end fastening nut two 6, right-end internal and external thread connecting pipe 7, high-pressure nozzle 8, scraper 9, cavity 10, left-end fastening nut two 11, left-end fastening nut one 12, left-end internal and external thread connecting pipe 13, feed bin 14, discharge bin 15, bracket 16, brush 17.

[0044] Example 1:

[0045] The embodiment is basically as shown in the attached Figure 1 The figure shows a belt cleaning device for anaerobic fermentation material transport, comprising a material transport mechanism and a belt cleaning mechanism. The belt cleaning mechanism is mounted on the material transport mechanism, which includes a conveyor belt conveyor 1, on which a rolling and flipping belt is mounted. A discharge bin 15 is mounted at the discharge end of the conveyor belt conveyor 1, with side panels on either side of the discharge bin 15. The belt cleaning structure includes a high-pressure nozzle 8 and a brush 17 mounted below the conveyor belt conveyor 1. The high-pressure nozzle 8 and brush 17 are used to clean the belt. The high-pressure nozzle 8 passes through the side panels of the discharge bin 15 through a cavity 10. The brush 17 is mounted on the side of the discharge bin 15 close to the conveyor belt conveyor and directly contacts the belt.

[0046] Specifically, the material transportation mechanism includes a conveyor belt conveyor 1, which is installed at an angle of 30 degrees, so as to realize the transportation of materials from low to high places; a bracket 16 for supporting the entire conveyor belt conveyor 1 is connected to the bottom of the conveyor belt conveyor 1, so as to ensure the stability and safety of the entire device, and the conveyor belt conveyor 1 is provided with a feed bin 14 for loading and temporarily storing materials to be transported at the lower feed end, and the materials are fed into the conveyor belt conveyor 1 from the feed bin 14, and a discharge bin 15 for receiving materials unloaded from the belt is installed at the high discharge end, and the inclination angle of the discharge end is 30 degrees. When the material is transported to the discharge end, the inclined discharge end causes the material to fall from the conveyor belt conveyor 1 into the discharge bin 15 under the action of gravity, thereby realizing efficient transportation and collection of materials. The discharge bin 15 is flanked by side panels, each with a corresponding waist-shaped hole 3. The waist-shaped hole 3 is elliptical and has a height range of 1 cm to 5 cm. By adjusting the height of the belt cleaning mechanism above the waist-shaped hole 3, the belt cleaning mechanism can be moved up and down, adapting to belts of varying heights and different cleaning requirements. This ensures that the belt cleaning mechanism always maintains optimal contact with the belt surface, thereby improving the cleaning effect. The pipeline of the high-pressure air pump 2 passes through the waist-shaped hole 3 and communicates with the belt cleaning mechanism. Furthermore, a belt cleaning mechanism is connected between the two waist-shaped holes 3.

[0047] The belt cleaning mechanism includes a cavity 10, with connecting pipes connected to both sides of the cavity 10. The outer surface of the connecting pipe is provided with a thread. The connecting pipe passes through the waist-shaped hole 3 and cooperates with the nut to fix the cavity 10 between the two waist-shaped holes 3. A high-pressure nozzle 8 for cleaning the belt is installed on the top of the cavity 10. The high-pressure nozzle 8 is located below the conveyor belt 1 and is aimed at the belt. High-pressure gas will be directly sprayed onto the belt through the high-pressure nozzle 8, blowing the material adhering to the belt into the discharge bin 15, thereby achieving belt cleaning. Figure 4 As shown, a brush 17 for cleaning the belt is installed on the side of the discharge bin 15 near the conveyor belt 1. The brush 17 is located below the conveyor belt 1 and is in direct contact with the belt. The portion of the brush 17 in contact with the belt has flexible bristles, which enable it to penetrate deeper into the tiny gaps on the belt surface for a more precise cleaning effect. This also reduces wear and scratches on the belt surface, extending the service life of the belt. In this embodiment, the nuts are fastening nuts, which include a right-end fastening nut 1 5, a right-end fastening nut 2 6, a left-end fastening nut 2 11, and a left-end fastening nut 1 12; the connecting tubes are internal and external thread connecting tubes, which include a right-end internal and external thread connecting tube 7 and a left-end internal and external thread connecting tube 13.

[0048] Specifically, such as Figure 2As shown, the belt cleaning mechanism includes, from right to left, a high-pressure air pipe 4, a right-end fastening nut 1 5, a right-end fastening nut 2 6, a right-end internal and external thread connecting pipe 7, a high-pressure nozzle 8, a cavity 10, a left-end fastening nut 2 11, a left-end fastening nut 1 12, and a left-end internal and external thread connecting pipe 13. One end of the high-pressure air pipe 4 is connected to the right end of the right-end internal and external thread connecting pipe 7, and the other end is connected to the high-pressure air pump 2, thereby realizing the stable transportation of high-pressure gas. Two fastening nuts are installed on the outer thread of the right-end internal and external thread connecting pipe 7: a right-end fastening nut 1 5 and a right-end fastening nut 2 6. The right side plate of the discharge bin 15 is located between these two fastening nuts. By rotating the two fastening nuts to move them toward each other, the right side plate of the discharge bin 15 can be clamped and fixed, thereby ensuring the fixation of the discharge bin 15. The left end of the right end inner and outer thread connecting pipe 7 is welded to the right end of the cavity 10, and a gas channel is provided inside the cavity 10. A high-pressure nozzle 8 is installed on the top of the cavity 10, and one end of the high-pressure air pipe 4 is connected to the gas channel and the high-pressure nozzle 8 through the right end inner and outer thread connecting pipe 7, and the other end of the high-pressure air pipe 4 is connected to the high-pressure air pump 2 for providing high-pressure gas to the cavity 10, so that the high-pressure gas flows to the high-pressure nozzle 8 through the right end inner and outer thread connecting pipe 7 and the gas channel, so that the high-pressure gas is directly sprayed onto the belt surface for cleaning, and the high-pressure air pump 2 can provide stable high-pressure gas to ensure that the high-pressure nozzle 8 can generate sufficient airflow, thereby efficiently removing residual materials on the belt, where the number of high-pressure nozzles 8 can be arranged side by side according to actual needs, and the left end of the cavity 10 is connected to the end of the left end inner and outer thread connecting pipe 13, and two fastening nuts are installed on the outer thread of the left end inner and outer thread connecting pipe 13: left end fastening nut one 12 and left end fastening nut two 11. The left side panel of the discharge bin 15 is positioned between these two fastening nuts. By rotating the two fastening nuts toward each other, the left side panel of the discharge bin 15 is clamped and secured, ensuring its stability. The fastening nuts and connecting tube arrangement not only allow for adjustment of the left and right positions of the belt cleaning mechanism and securement of the discharge bin 15, but also allow for arbitrary rotational adjustments of the high-pressure nozzle 8 by rotating the connecting tube, enabling multi-angle cleaning and effectively removing residual material from every corner, thereby improving cleaning efficiency. In this embodiment, the high-pressure nozzle's rotation angle ranges from 0 to 360 degrees.

[0049] like Figure 3As shown, before cleaning the materials, it is necessary to assemble the anaerobic fermentation material transport belt cleaning device. First, pass the right end inner and outer thread connecting pipe 7 through the right side waist-shaped hole 3 of the discharge bin 15, and install the right end fastening nut 1 5 and the right end fastening nut 2 6 on the outer thread of the right end inner and outer thread connecting pipe 7 in sequence, wherein the right end fastening nut 1 5 is located outside the discharge bin 15, and the right end fastening nut 2 6 is located inside the discharge bin 15. By tightening these two fastening nuts, the right side plate of the discharge bin 15 is clamped and fixed between the two; when the left end inner and outer thread connecting pipe 13 is passed through the discharge bin 15 The left waist-shaped hole 3 is installed on the outer thread of the left inner and outer thread connecting tube 13, and the left end fastening nut 12 and the left end fastening nut 2 11 are installed in sequence, so that the left end fastening nut 12 is located outside the discharge bin 15 and the left end fastening nut 2 11 is located inside the discharge bin 15. By properly tightening the two fastening nuts, the left side plate of the discharge bin 15 is clamped and fixed between the two; thereby completing the assembly of the anaerobic fermentation material transport belt cleaning device; finally, start the anaerobic fermentation material transport belt cleaning device, conduct a cleaning effect test, and select the parameters with the best cleaning effect and performance.

[0050] like Figure 4 As shown, when cleaning the materials: start the anaerobic fermentation material transport belt cleaning device, the materials will be transported from the lower feed bin 14 to the higher discharge bin 15 through the conveyor belt 1, and most of the materials will fall directly from the belt into the discharge bin 15 under the action of gravity. The materials remaining on the belt will be cleaned in sequence by the high-pressure nozzle 8 and the brush 17. First, the high-pressure nozzle 8 cleans: start the high-pressure air pump 2, and the high-pressure air pump 2 inflates the gas channel inside the cavity 10 through the high-pressure air pipe 4. The high-pressure gas flows into the gas channel and is sprayed directly onto the belt surface from the high-pressure nozzle 8 at the top of the cavity 10, blowing the materials remaining on the belt into the discharge bin 15. The number and position of the high-pressure nozzles 8 can be adjusted according to actual needs to achieve multi-angle and all-round cleaning. During the secondary cleaning with the brush 17: the belt treated by the high-pressure nozzle 8 will be treated again with the brush 17. The soft bristles of the brush 17 can penetrate into the tiny gaps on the belt surface and remove fine particles and stains that are difficult for high-pressure gas to reach. That is, the brush 17 further removes tiny particles and residues on the belt surface through physical friction, ensuring that the belt surface is cleaner. The brush 17 can evenly contact the belt surface to ensure that each area is treated consistently, avoiding uneven cleaning caused by uneven spraying of the high-pressure nozzle 8, and the brush 17 is equipped with flexible bristles, which can reduce wear on the belt surface and extend the service life of the belt.

[0051] This solution adopts a dual cleaning method of "high-pressure nozzle 8 + brush 17", in which the high-pressure nozzle 8 is used to spray the residual materials on the belt through high-pressure gas to remove a large amount of materials adhering to the belt and some hard-to-reach corners, while the brush 17 is responsible for secondary cleaning of the belt. The belt treated by the high-pressure nozzle 8 is cleaned again by the brush to deal with the remaining tiny particles and ensure that the belt surface is cleaner. The high-pressure nozzle 8 and the brush 17 work together to achieve all-round cleaning of the material without dead angles. At the same time, the high-pressure nozzle 8 and the brush 17 are both arranged under the conveyor belt, that is, the rotation position of the belt or the position where the belt is not working, so that the belt can be cleaned while transporting materials in the forward direction, which not only ensures the cleaning effect but also takes into account production efficiency. In addition, this solution can also adjust the air spray pressure and the position of the belt cleaning mechanism according to the ambient temperature and the agglomeration of the material, that is, the air spray pressure of the high-pressure nozzle 8 can be adjusted by adjusting the high-pressure air pump 2, and the position and angle of the high-pressure nozzle 8, the up and down, left and right positions of the belt cleaning mechanism and the position of the brush 17 can be adjusted by adjusting the waist-shaped hole 3, the fastening nut and the connecting pipe, so that the device can completely cover the belt and be in close contact with the belt, thereby achieving cleaning of the belt without dead angles and improving the cleaning effect.

[0052] This solution uses the dual cleaning method of "high-pressure nozzle 8 + brush 17" to not only achieve more thorough, uniform and efficient belt cleaning, but also extend the service life of the belt, while ensuring the cleaning effect while taking into account production efficiency.

[0053] Example 2:

[0054] The difference between this embodiment and the first embodiment is that, in this embodiment, the number of high-pressure nozzles 8 is 4-8, and the spray pattern of the high-pressure nozzles 8 is fan-shaped. The number of high-pressure nozzles 8 can be flexibly adjusted according to the cleaning effect test results, thereby reducing the cost of the device. The cleaning effect test includes a high-pressure nozzle 8 pressure test, a high-pressure nozzle 8 vertical position test, a high-pressure nozzle 8 left and right position test, a high-pressure nozzle 8 rotation angle test, and a brush 17 cleaning effect test. The parameters are ultimately determined based on the test results to balance the relationship between the number of high-pressure nozzles and the spray range, thereby ensuring that the cleaning effect and performance are optimized.

[0055] Specifically, the high-pressure nozzle 8 pressure test: set an initial pressure value of the high-pressure nozzle 8, gradually adjust the air pressure, observe the cleaning effect under different air pressures, record the cleaning effect and cleaning range corresponding to each air pressure value, and according to the test results, select the optimal air pressure value that can effectively remove the material without causing damage to the belt.

[0056] Test the upper and lower positions of the high-pressure nozzle 8: Set the high-pressure nozzle 8 to the initial position; gradually adjust the upper and lower positions of the high-pressure nozzle 8 by adjusting the height of the waist-shaped holes 3 on the left and right sides, and observe the cleaning effects at different heights, and record the cleaning effects corresponding to each height value; according to the test results, select the height position that can cover the maximum cleaning range and have the best effect.

[0057] Test the left and right position of the high-pressure nozzle 8: Set the high-pressure nozzle 8 to the initial position, and gradually adjust the left and right fastening nuts and connecting pipes at both ends to adjust the left and right positions of the high-pressure nozzle 8. Observe the cleaning effects at different positions, and record the cleaning effects corresponding to each position value. According to the test results, select the position that can evenly cover the entire belt width and has the best effect.

[0058] High-pressure nozzle 8 rotation angle test: Set the initial rotation angle of the high-pressure nozzle 8, and adjust the rotation angle of the high-pressure nozzle 8 by gradually adjusting the fastening nuts and connecting pipes at the left and right ends. Observe the cleaning effects at different angles, and record the cleaning effects corresponding to each angle value. According to the test results, select the rotation angle that can fully cover the belt surface and has the best effect.

[0059] Test the cleaning effect of brush 17: Set brush 17 at the initial position, gradually adjust the position of brush 17, observe the cleaning effect under different settings, record the cleaning effect corresponding to each setting value, and according to the test results, select the best position of brush 17 that can effectively remove materials without causing damage to the belt.

[0060] Finally, according to the above cleaning test results, it was found that under normal circumstances, the parameters for the cleaning effect and performance to reach the best state are: 6 high-pressure nozzles 8, and the air pressure value of a single high-pressure nozzle 8 is: 5-10MPa.

[0061] Specifically, such as Figure 5As shown, 6 high-pressure nozzles 8 are arranged side by side on the top of the cavity 10. The air spray pressure of each high-pressure nozzle 8 is 5-10 MPa, and the spray shape is fan-shaped. Under this air pressure, the spray width of each high-pressure nozzle 8 is 20 cm, which has a strong spray force and can effectively remove residual materials on the belt. The distance between adjacent high-pressure nozzles 8 is 20 cm, and the spray width of each high-pressure nozzle 8 is 20 cm, so that the spray range is continuous without overlap or omission. When the 6 high-pressure nozzles 8 are arranged side by side, the total spray width reaches about 1.1 meters, which can cover the width of the belt on the conveyor belt 1, ensuring that the entire belt surface can obtain a uniform and powerful cleaning effect. Specifically, the high-pressure nozzle 8 is located at the upper right of the cavity 10 and below the belt. The high-pressure nozzle 8 sprays high-pressure gas from bottom to top to clean the material remaining on the belt. The high-pressure nozzle 8 has a strong cleaning power and can directly impact the residual material on the surface of the belt. Its high-pressure airflow can effectively peel off the material adhering to the belt. At the same time, the bottom-up spraying method can reduce the material from being blown to other areas or falling back on the belt, thereby avoiding secondary pollution. The setting of the high-pressure nozzle position does not interfere with the function of the belt to transport materials forward. While the material is being transported normally, the belt can be continuously cleaned and maintained. This synchronous cleaning method ensures the cleaning effect while taking into account production efficiency.

[0062] Based on cleaning test results, this solution optimized and selected the optimal parameters for the number, air pressure, spacing, and angle of high-pressure nozzles 8, ensuring efficient cleaning without blind spots and significantly improving the cleaning performance of the cleaning device. Specifically, by precisely setting the air pressure, the high-pressure nozzles 8 generate sufficient spray force to effectively remove residual material from the belt. Furthermore, the rational arrangement and spray width of the high-pressure nozzles 8 ensure uniform cleaning across the entire belt surface, further enhancing the overall cleaning effect.

[0063] Example 3:

[0064] The difference between this embodiment and embodiment 1 is that, in this embodiment, a scraper 9 for cleaning the cavity 10 is installed on the discharge bin 15. The scraper 9 is parallel to the cavity 10 and is located at the bottom of the cavity 10, directly contacting the surface of the cavity 10. In addition, a flexible brush is provided on the part of the scraper 9 that contacts the belt.

[0065] Specifically, such as Figure 6As shown, scrapers 9 are installed on the left and right side panels of the discharge bin 15, which are parallel to the cavity 10. The scrapers 9 are located at the bottom of the cavity 10 and are in direct contact with the cavity 10, which can effectively scrape off the material attached to the surface of the cavity 10. In addition, the part of the scraper 9 that contacts the belt is provided with a flexible brush. The softness of the flexible brush can reduce the wear and scratches on the surface of the cavity 10, extending the service life of the cavity 10. At the same time, the flexible brush can better fit the curved surface of the cavity 10, ensuring that every corner can be thoroughly cleaned, achieving a more comprehensive cleaning effect. The scraper 9 is used to clean the material attached to the surface of the cavity 10. After the material transportation is completed, the cavity 10 is attached with the material sprayed by the high-pressure nozzle 8. The relative position between the scraper 9 and the cavity 10 can be adjusted by adjusting the fastening nut and the connecting pipe to ensure that the scraper 9 is in close contact with the surface of the cavity 10. Then, the cavity 10 is rotated so that the cavity 10 rubs on the scraper 9, thereby removing the material attached to the cavity 10. The provision of the scraper 9 ensures that the surface of the cavity 10 is thoroughly cleaned, avoiding material residue, thereby enabling the equipment to operate reliably for a long time.
