Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically a material conveyor belt cleaning device. Background Technology
[0002] Food processing refers to the process of using agricultural, forestry, animal husbandry, and fishery products as raw materials, and then processing and blending them to produce various processed foods. Material conveyor belts are indispensable equipment in the food processing industry, responsible for the efficient and hygienic transport of raw materials, semi-finished products, and finished products along the production line.
[0003] The material conveyor belt cleaning device consists of a brush, brush frame, support, adjustment mechanism, and dust collector. It uses the friction between the brush and the surface of the conveyor belt to brush away the residue. The suction device generates negative pressure to suck the residue from the surface of the conveyor belt into the suction port and then transports it to the dust collector through the pipeline.
[0004] Existing conveyor belt cleaning devices in food production processes suffer from limitations due to material characteristics and a single cleaning method. As a result, residual materials on the surface and in the gaps of the conveyor belt are difficult to remove completely. At the same time, the dust and debris generated during the cleaning process are easily blown and spread, causing environmental pollution in the workshop and affecting the hygiene and quality of food production. Therefore, a material conveyor belt cleaning device is proposed to address the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, current conveyor belt cleaning devices in food production processes suffer from limitations due to material characteristics and limited cleaning methods. This makes it difficult to completely remove residual materials from the surface and gaps of the conveyor belt. Furthermore, the dust and debris generated during the cleaning process are easily dispersed, causing environmental pollution in the workshop and affecting the hygiene and quality of food production. This invention proposes a material conveyor belt cleaning device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A material conveyor belt cleaning device of this utility model includes a belt conveyor. A filter box is fixedly installed on the upper part of one end of the belt conveyor. A first motor is fixedly installed on one end of the filter box. A partition is vertically and fixedly installed in the center of the filter box. Multiple filter holes are circularly arrayed in the center of the partition. A rotating shaft is rotatably installed in the center of the partition. Both ends of the rotating shaft are rotatably installed in the filter box via bearings. The rotating shaft of the first motor is fixedly connected to one end of the rotating shaft. Brushes and fan blades are respectively provided on both sides of the partition and fixedly installed on the rotating shaft. Dust suction pipes are fixedly installed on both sides of one end of the filter box. Connecting pipes are fixedly connected to both sides of the other end of the filter box. A drying box is fixedly installed in one end of the belt conveyor. The other end of the connecting pipe... The ends of the suction pipe are fixedly connected to both sides of the drying chamber. A dust suction port is provided on one side of the upper end of the drying chamber and is fixedly installed inside the belt conveyor. The other end of the suction pipe is fixedly connected to both ends of the dust suction port. Two roller brushes are arranged parallel to each other in the vertical plane below the dust suction port and are rotatably installed inside the belt conveyor. Spray pipes are provided on both sides below the roller brushes and are fixedly installed inside the belt conveyor. A connecting shaft is provided between the spray pipes and the drying chamber and is rotatably installed inside the belt conveyor. An arc-shaped scraper is fixedly installed on the connecting shaft. A guide trough is fixedly installed at the bottom of the belt conveyor. A water tank is fixedly installed at the bottom of the guide trough. An arc-shaped filter plate is fixedly installed on the top of the water tank. Through the coordinated operation of the brushes, fan blades, suction, and drying components, the material conveyor belt is efficiently cleaned, improving the cleanliness of the conveyor belt and the hygiene standards of food production.
[0007] Preferably, the filter box has a cleaning port on the side connected to the dust suction pipe, and a sealing door is hinged inside the cleaning port. The cleaning port facilitates regular cleaning and maintenance of the filter box, avoiding blockage or efficiency reduction caused by long-term accumulation. The hinged design of the sealing door makes the cleaning process more convenient, while ensuring the airtightness of the filter box, preventing the leakage of dust and debris, and maintaining a clean environment in the workshop.
[0008] Preferably, both ends of the connecting shaft pass through the belt conveyor and are fixedly installed with tie rods. A cylinder is rotatably mounted on the belt conveyor at the lower end of the tie rod. The piston rod of the cylinder is rotatably connected to the lower end of the tie rod. Through the extension and retraction of the cylinder, the contact and separation between the arc-shaped scraper and the conveyor belt can be easily controlled, which improves the automation level of the cleaning device, reduces the labor intensity of the operators, and ensures the consistency and stability of the cleaning effect.
[0009] Preferably, a second motor is fixedly installed on one side of the central part of the belt conveyor. The rotating shaft of the second motor is fixedly connected to one end of the roller brush. The other end of the roller brush passes through the belt conveyor and is fixedly installed with a rotating wheel. The rotating wheels rotate in cooperation with each other through a belt. Driven by the second motor, the roller brush can rotate to perform deep cleaning of the conveyor belt. The cooperation transmission method between the rotating wheel and the belt is simple and reliable, ensuring the stable rotation of the roller brush.
[0010] Preferably, a water pump is fixedly installed on one side of the bottom of the belt conveyor. The water inlet of the water pump is fixedly connected to one side of the lower end of the water tank, and the water outlet of the water pump is fixedly connected to a T-pipe. The T-pipe is fixedly connected to a spray pipe. The water pump draws water from the water tank and delivers it to the spray pipe, which then sprays the water evenly onto the conveyor belt. Combined with the scrubbing action of the roller brush, the conveyor belt becomes cleaner.
[0011] Preferably, heating wires are fixedly installed at both ends of the drying chamber, and two baffles are fixedly installed in parallel inside the drying chamber. Multiple air holes are arrayed on each baffle. The heating wires generate hot air inside the drying chamber to dry the conveyor belt. The baffles and air holes allow the hot air to be distributed more evenly inside the drying chamber, improving drying efficiency.
[0012] The advantages of this utility model are:
[0013] 1. This utility model, during food production, involves starting a water pump to deliver water from a tank to a spray nozzle via a three-way pipe. The spray nozzle sprays water onto the conveyor belt surface. Simultaneously, a second motor is activated, driving a rotating shaft to rotate a roller brush. The roller brush scrubs the conveyor belt surface, removing dirt and grime. Simultaneously, a first motor is activated, rotating the shaft and causing the fan blades on one side of the partition to rotate. This creates negative pressure within the filter box, drawing dust and impurities from around the conveyor belt into the filter box through a suction pipe. The dust is then filtered by the filter holes on the partition. A brush on the rotating shaft continuously cleans the filter holes on the partition to prevent clogging. Filtered air enters the drying chamber through a connecting pipe. The heating wire inside the drying chamber is energized and heats the air before it is blown onto the material conveyor belt for drying. This structural design achieves efficient cleaning, dust removal, drying, and wastewater recycling. It solves the problem that existing conveyor belt cleaning devices in food production processes often fail to completely remove residual materials from the surface and gaps of the conveyor belt due to material characteristics and a single cleaning method. At the same time, the dust and debris generated during the cleaning process are easily scattered and cause environmental pollution in the workshop, thus affecting the hygiene and quality of food production. This design improves cleaning efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figures 1-5As shown, a material conveyor belt cleaning device includes a belt conveyor 1. A filter box 2 is fixedly installed on the upper part of one end of the belt conveyor 1. A first motor 8 is fixedly installed on one end of the filter box 2. A partition 5 is vertically and fixedly installed in the center of the filter box 2. Multiple filter holes are arranged in a circular array in the center of the partition 5. A rotating shaft 6 is rotatably installed in the center of the partition 5. Both ends of the rotating shaft 6 are rotatably installed in the filter box 2 through bearings. The rotating shaft of the first motor 8 is fixedly connected to one end of the rotating shaft 6. Brushes 9 and fan blades 7 are respectively provided on both sides of the partition 5 and fixedly installed on the rotating shaft 6. Dust suction pipes 3 are fixedly installed on both sides of one end of the filter box 2. Two suction pipes 3 are fixedly installed on the other end of the filter box 2. A connecting pipe 4 is fixedly connected to each side. A drying chamber 26 is fixedly installed inside one end of the belt conveyor 1. The other ends of the connecting pipes 4 are fixedly connected to both sides of the drying chamber 26. A dust suction port 16 is provided on one side of the upper end of the drying chamber 26 and is fixedly installed inside the belt conveyor 1. The other ends of the dust suction pipe 3 are fixedly connected to both ends of the dust suction port 16. Two roller brushes 14 are arranged parallel to each other in the vertical plane below the dust suction port 16 and are rotatably installed inside the belt conveyor 1. Spray pipes 15 are provided on both sides below the roller brushes 14 and are fixedly installed inside the belt conveyor 1. A connecting shaft 17 is provided between the spray pipes 15 and the drying chamber 26 and is rotatably installed inside the belt conveyor 1. A fixed component is installed on the connecting shaft 17. An arc-shaped scraper 18 is installed. A guide trough 11 is fixedly installed at the bottom of the belt conveyor 1. A water tank 12 is fixedly installed at the bottom of the guide trough 11. An arc-shaped filter plate 13 is fixedly installed at the top of the water tank 12. During operation, in the food production process, the water pump 19 is started to transport water from the water tank 12 to the spray pipe 15 through the three-way pipe 20. The spray pipe 15 sprays water onto the surface of the conveyor belt. The second motor 23 is started, which drives the roller brush 14 to rotate through the rotating shaft. The roller brush 14 scrubs the surface of the material conveyor belt to remove the dirt attached to the conveyor belt. The first motor 8 is started to drive the rotating shaft 6 to rotate, which in turn causes the fan blades 7 on one side of the partition 5 to rotate, creating a negative pressure in the filter box 2. Dust and impurities around the material conveyor belt are then removed. The air is drawn into the filter box 2 through the suction pipe 3. The dust is intercepted by the filter holes on the partition 5, thus achieving filtration. The brush 9 on the rotating shaft 6 continuously cleans the filter holes on the partition 5 to prevent clogging. The filtered air enters the drying box 26 through the connecting pipe 4. The heating wire 27 in the drying box 26 is energized and heats up to heat the air, which is then blown onto the material conveyor belt for drying. Wastewater and impurities generated during the cleaning process flow into the water tank 12 through the guide channel 11. The arc-shaped filter plate 13 on the top of the water tank 12 performs secondary filtration of the wastewater, allowing the water in the water tank 12 to be recycled. When it is necessary to clean the dust in the filter box 2, the sealed door 10 at the cleaning port can be opened to clean the inside of the filter box 2.
[0023] The filter box 2 has a cleaning port on one side connected to the dust suction pipe 3, and a sealing door 10 is hinged inside the cleaning port. During operation, the cleaning port is closed during food production, and the sealing door 10 ensures the airtightness of the filter box 2 to prevent dust leakage. When it is necessary to clean the inside of the filter box 2, the sealing door 10 is opened, and the operator can clean and maintain the filter holes, brushes 9 and other components. After cleaning, the sealing door 10 is closed to ensure the normal operation of the device.
[0024] Both ends of the connecting shaft 17 pass through the belt conveyor 1 and are fixedly installed with pull rods 24. A cylinder 25 is rotatably mounted on the belt conveyor 1 at the lower end of the pull rod 24. The piston rod of the cylinder 25 is rotatably connected to the lower end of the pull rod 24. During operation, in the food production process, the cylinder 25 is in the initial state, and the pull rod 24 maintains the stable position of the connecting shaft 17, so that the arc-shaped scraper 18 can normally scrape off the impurities on the surface of the nozzle 15.
[0025] A second motor 23 is fixedly installed on one side of the central part of the belt conveyor 1. The rotating shaft of the second motor 23 is fixedly connected to one end of the roller brush 14. The other end of the roller brush 14 passes through the belt conveyor 1 and is fixedly installed with a rotating wheel 21. The rotating wheels 21 rotate in coordination with each other through a belt 22. During operation, in the food production process, the second motor 23 rotates continuously, driving the roller brush 14 to clean the material conveyor belt through the rotating shaft. The rotating wheels 21 and belt 22 at both ends of the roller brush 14 rotate in coordination to ensure that the two roller brushes 14 operate synchronously and improve the cleaning effect.
[0026] A water pump 19 is fixedly installed on one side of the bottom of the belt conveyor 1. The water inlet of the water pump 19 is fixedly connected to the lower side of the water tank 12, and the water outlet of the water pump 19 is fixedly connected to a three-way pipe 20. The three-way pipe 20 is fixedly connected to the spray pipe 15. During operation, in the food production process, the water pump 19 is started according to the cleaning needs, and the water in the water tank 12 is transported to the spray pipe 15. The spray pipe 15 sprays water evenly on the surface of the conveyor belt, working in conjunction with the scrubbing action of the roller brush 14 to ensure that the surface of the conveyor belt is thoroughly cleaned.
[0027] Heating wires 27 are fixedly installed at both ends of the drying chamber 26. Two baffles 28 are fixedly installed in parallel inside the drying chamber 26. Multiple air holes are arrayed on the baffles 28. During operation, the heating wires 27 are energized and heated during food production to dry the conveyor belt entering the drying chamber 26. The air holes on the baffles 28 can evenly distribute air inside the drying chamber 26, improving drying efficiency, while preventing dust from directly impacting the heating wires 27 and extending their service life.
[0028] Working principle: During food production, water pump 19 is started, and water from water tank 12 is delivered to spray nozzle 15 through three-way pipe 20. Spray nozzle 15 sprays water onto the conveyor belt surface. Second motor 23 is started, which drives roller brush 14 to rotate via rotating shaft. Roller brush 14 scrubs the surface of the material conveyor belt, removing dirt adhering to it. First motor 8 is started, which drives rotating shaft 6 to rotate, thereby causing fan blades 7 on one side of partition 5 to rotate. This creates negative pressure in filter box 2, and dust and impurities around the material conveyor belt are sucked into filter box 2 through suction pipe 3. The dust is intercepted by the filter holes on partition 5, achieving the desired effect. The filter is continuously cleaned by the brush 9 on the rotating shaft 6, which cleans the filter holes on the partition 5 to prevent clogging. The filtered air enters the drying chamber 26 through the connecting pipe 4. The heating wire 27 inside the drying chamber 26 is energized and heats up the air, which is then blown onto the material conveyor belt for drying. Wastewater and impurities generated during the cleaning process flow into the water tank 12 through the guide channel 11. The arc-shaped filter plate 13 on the top of the water tank 12 performs secondary filtration of the wastewater, allowing the water in the water tank 12 to be recycled. When it is necessary to clean the dust inside the filter box 2, the sealing door 10 at the cleaning port can be opened to clean the inside of the filter box 2.
