Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of conveyor belt auxiliary equipment, and specifically relates to a conveyor belt cleaning mechanism. Background Technology
[0002] The wet separation method for slag after municipal solid waste incineration power generation requires a large amount of conveyor belt transport during the production process. If the conveyor belt surface is not cleaned in a timely and effective manner, mud and sand can easily fall on passersby, equipment surfaces, and the ground. Conventional sweepers and electric rollers are not clean enough or have a very short service life, which seriously affects production needs. For example, excessive fine mud and sand adhering to the surface of eddy current conveyor belts also seriously affects the sorting of aluminum metal.
[0003] In addition, during the material transport process of a belt conveyor, if residual material enters the bearing housing of the drum or idler, it will accelerate the wear of the bearing. Material adhering to the surface of the drum or idler will tear and fray the conveyor belt surface, accelerating the wear and damage of the conveyor belt.
[0004] If materials enter the tail roller or vertical tension roller of a belt conveyor, they will adhere to and clump together, causing the conveyor belt to deviate, increasing wear on the conveyor belt, and even tearing the rubber coating of the roller, resulting in mud and sand falling everywhere, seriously polluting the production site and machinery, and significantly increasing manual cleaning costs. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a conveyor belt cleaning mechanism to solve the problem that the surface of the conveyor belt is easily damaged by the deposits.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A conveyor belt cleaning mechanism, comprising:
[0007] The top of the collection hopper is connected to the conveyor belt via a fixed seat, and the collection hopper is filled with cleaning fluid.
[0008] A roller is rotatably disposed in the collection hopper. The direction of rotation of the roller is opposite to the direction of travel of the conveyor belt. Bristles are spaced apart on the outer periphery of the roller. The bristles are intermittently immersed in the cleaning liquid in the collection hopper during the rotation of the roller.
[0009] A scraper assembly is located downstream of the hopper, and the scraper assembly is in contact with the surface of the conveyor belt.
[0010] Compared with existing technologies, the above technical solutions have the following beneficial effects:
[0011] By setting up a collection hopper, the roller rotates and drives the brush bristles to clean the surface of the conveyor belt. The collection hopper can collect the debris that falls off the conveyor belt. At the same time, the cleaning fluid poured into the collection hopper cleans the brush bristles during the rotation of the roller, preventing the bristles from clumping together and becoming unusable. Moreover, the roller is set in the collection hopper to prevent mud and sand from splashing. The brush bristles, which are covered with liquid, are more likely to clean the mud and sand off the surface of the conveyor belt, resulting in less damage to the surface of the conveyor belt.
[0012] Based on the above technical solution, the embodiments of this application can be further improved as follows:
[0013] In one embodiment, a sand discharge port is provided at the bottom of the hopper, and a gate valve is installed in the sand discharge port.
[0014] The sand and mud collected in the hopper can be quickly discharged through the sand discharge port, and the gate valve can be closed when the drum is rotating and can be selectively opened and closed to discharge sand and mud.
[0015] In one embodiment, the hopper is provided with a beater bar that is parallel to the roller at intervals, and the beater bar is used to contact the brush bristles when the roller rotates.
[0016] The roller rotates to make the brush bristles contact with the beating rod, and removes the mud and sand stuck to the brush bristles.
[0017] In one embodiment, the system further includes a plurality of nozzles, which are spaced apart along a direction perpendicular to the conveyor belt and are located between the hopper and the scraper assembly.
[0018] The nozzles positioned between the scraper assembly and the rollers can clean the conveyor belt surface again, and the downstream scraper assembly scrapes the surface clean.
[0019] In one embodiment, the scraper assembly includes:
[0020] A fixing frame is provided on the bottom surface of the conveyor belt, wherein a strip groove is provided;
[0021] A scraper passes through the slot and contacts the surface of the conveyor belt;
[0022] An adjustment component is disposed at the bottom of the fixed frame. The adjustment component is connected to the side of the scraper away from the conveyor belt and is used to push the scraper against the surface of the conveyor belt.
[0023] In one embodiment, the adjusting assembly includes a sleeve and an elastic element. The sleeve is installed at the bottom of the fixing frame, and the elastic element is disposed inside the sleeve. The bottom end of the elastic element is connected to the bottom of the sleeve, and the top end of the elastic element is connected to the bottom end of the scraper for pushing the scraper upward.
[0024] By using an elastic element installed inside the sleeve, the scraper can be pushed against the surface of the conveyor belt, ensuring that the scraper is always in contact with the surface of the conveyor belt. This prevents excessive gaps caused by scraper wear, which would require manual adjustment at regular intervals, thus ensuring the normal operation of the conveyor belt and production line.
[0025] In one embodiment, an adjusting bolt is screwed to the bottom of the sleeve, and the end of the adjusting bolt abuts against the bottom of the elastic element.
[0026] The adjusting screw can be used to compensate for the wear of the scraper and ensure that the scraper exerts sufficient force on the conveyor belt surface.
[0027] In one embodiment, the bristle diameter is 0.2-0.4 mm, the bristle length is 80-100 mm, and the contact distance between the bristle and the conveyor belt surface is 4-5 mm. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0043] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and provide a conveyor belt cleaning mechanism. In order to increase the service life and cleanliness of the scraper, a technical method of washing the conveyor belt surface with water and air is added in front of the scraper. This solves the technical problems of conventional sweepers and electric rollers not cleaning cleanly or having a very short service life. It ensures that the slag is treated by wet separation after the resource recovery of municipal solid waste incineration power generation. During the conveying process, the conveyor belt surface can be kept clean, mud and sand will not splash everywhere, and metal separation will be more thorough.
[0044] like Figure 1-5As shown, the conveyor belt cleaning mechanism provided by this utility model includes: a collection hopper 2, a fixed base 3, a roller 4, and a scraper assembly 6.
[0045] A fixing seat 3 is installed at the top or opening of the collecting hopper 2. The fixing seat 3 is fixed to the bottom of the conveyor belt 1, so that the collecting hopper 2 is connected to the conveyor belt 1 through the fixing seat 3. The collecting hopper 2 is filled with cleaning fluid. In this embodiment, water can be used instead of cleaning fluid.
[0046] The roller 4 is rotatably disposed in the collection hopper 2. The rotation direction of the roller 4 is opposite to the walking direction of the conveyor belt 1. The outer circumference of the roller 4 is provided with bristles 5, which are made of nylon. The bristles 5 are intermittently immersed in the cleaning liquid of the collection hopper 2 during the rotation of the roller 4. The roller 4 is driven to rotate by a motor located outside the collection hopper 2, and its output end is connected to the end of the roller 4. Specifically, the optimal speed of the roller 4 is about 120 revolutions per minute, while the conveyor belt 1 travels at 23-50 meters per minute. The mud and sand on the surface of the conveyor belt 1 are quickly rolled and brushed into the collection hopper 2. The mud and sand adhering to the roller brush will fall directly to the bottom of the collection hopper 2 after being washed by the water in the collection hopper 2.
[0047] The scraper assembly 6 is located downstream of the hopper 2. The scraper assembly 6 is in contact with the surface of the conveyor belt 1 and is used to remove the remaining mud and sand after the roller brush formed by the roller 4 and the bristles 5 has cleaned the material.
[0048] By setting up a collection hopper 2, the roller 4 rotates and drives the brush bristles 5 to clean the surface of the conveyor belt 1. The collection hopper 2 can collect the attached debris that falls off the conveyor belt 1. At the same time, the cleaning fluid poured into the collection hopper 2 cleans the brush bristles 5 during the rotation of the roller 4, preventing the brush bristles 5 from sticking to mud and sand and becoming unusable. Moreover, the roller 4 is set in the collection hopper 2, which can prevent mud and sand from splashing. Furthermore, the brush bristles 5, after being covered with liquid, can more easily clean the mud and sand from the surface of the conveyor belt 1, with less damage to the surface of the conveyor belt 1.
[0049] To facilitate centralized sand discharge, a sand discharge port 7 is provided at the bottom of the collection hopper 2. A gate valve is installed in the sand discharge port 7 (not shown in the figure). The sand discharge port 7 can be connected to a sand discharge pipe to facilitate the discharge of mud and sand in the collection hopper 2. The mud and sand collected in the collection hopper 2 can be discharged quickly through the sand discharge port 7. The gate valve can be closed when the drum 4 is rotating and can be selectively opened to discharge mud and sand when needed.
[0050] The hopper 2 is provided with a beater 8 that is parallel to the roller 4 at intervals. The beater 8 can be made of round steel. The beater 8 is used to contact the brush bristles 5 when the roller 4 rotates. The rotation of the roller 4 drives the brush bristles 5 to contact the beater 8, which can further clean away the mud and sand on the brush bristles 5 that were not removed after being washed with water in the hopper 2.
[0051] When the conveyor belt 1 is initially cleaned by the roller 4, the water-brush can extend the service life of the electric roller 4 and prevent the nylon brush from clumping after adhering to mud and sand. The inside of the collection hopper 2 is welded with round steel as scraper 602 for the nylon roller brush, which is 50 mm away from the surface of the nylon roller 4. When the roller 4 is working, the nylon brush will scrape the mud and sand on the surface of the conveyor belt 1 into the mud and sand collection hopper 2. The mud and sand adhering to the brush bristles 5 are kept clean by the water and the collision of the round steel in the collection hopper 2 at a speed of 120 revolutions per minute, thus maintaining the self-cleaning of the brush bristles 5 of the nylon roller 4.
[0052] It also includes a plurality of nozzles 9, which are spaced apart along a direction perpendicular to the walking direction of the conveyor belt 1, and the nozzles 9 are located between the hopper 2 and the scraper assembly 6;
[0053] The nozzles positioned between the scraper assembly 6 and the roller 4 can clean again and scrape the surface of the conveyor belt 1 clean through the downstream scraper assembly 6.
[0054] After initial cleaning by the roller brush, the conveyor belt 1 is cleaned again by the nozzle. When the conveyor belt 1 reaches the position of the dual-fluid nozzle after passing through the roller brush, the water is pressurized by 0.7MP compressed air to wash away the mud and sand on the conveyor belt 1. At this time, the surface of the conveyor belt 1 has been cleaned. When the surface of the conveyor belt 1 passes through the scraper 602, the movement of the conveyor belt 1 will scrape off the water vapor on the belt surface to ensure that the conveyor belt 1 is clean and the normal operation of production.
[0055] In this embodiment, the scraper assembly 6 includes: a fixing frame 601, a scraper 602, and an adjustment assembly 604.
[0056] The fixing frame 601 can be made of square tube and is set on the bottom surface of the conveyor belt 1. It has a strip-shaped slot. The scraper 602 is installed on the mounting plate 603. The mounting plate 603 extends into the bottom of the fixing frame 601 through the slot. The scraper 602 passes through the slot and contacts the surface of the conveyor belt 1. The adjusting component 604 is set at the bottom of the fixing frame 601. The adjusting component 604 is connected to the side of the scraper 602 away from the conveyor belt 1. Specifically, the adjusting component 604 is connected to the mounting plate 603 of the scraper 602 and is used to push the scraper 603 against the surface of the conveyor belt 1.
[0057] The adjustment assembly 604 is provided in two sets, located at both ends of the fixed frame 601 respectively. The adjustment assembly 604 includes a sleeve 6041 and an elastic element 6042. The sleeve 6041 is installed at the bottom of the fixed frame 601, and the elastic element 6042 is disposed inside the sleeve 6041. The bottom end of the elastic element 6042 is connected to the bottom of the sleeve 6041, and the top end of the elastic element 6042 is connected to the bottom end of the scraper 603 for pushing the scraper 602 upward.
[0058] By using the elastic element 6042 installed inside the sleeve 6041, the scraper 602 can be pushed towards the surface of the conveyor belt 1, ensuring that the scraper 602 is in constant contact with the surface of the conveyor belt 1. This prevents excessive gaps caused by wear of the scraper 603, which would require manual adjustment at regular intervals, thereby ensuring the normal operation of the conveyor belt 1 and the production line.
[0059] Furthermore, an adjusting bolt 6043 is screwed to the bottom of the sleeve 6041. The end of the adjusting bolt 6043 abuts against the bottom of the elastic member 6042. By tightening or loosening the adjusting bolt 6043, the tightness of the compression of the elastic member 6042 can be adjusted. In turn, the adjusting screw can be used to compensate for the wear of the scraper 602, ensuring that the scraper 602 has sufficient spreading force on the surface of the conveyor belt 1.
[0060] Among them, scraper 602 is a polyurethane scraper, specifically a special synthetic polyurethane of 90 Shore A;
[0061] The brush bristles 5 have a wire diameter of 0.2-0.4 mm, a length of 80-100 mm, and a contact distance of 4-5 mm between the brush bristles 5 and the surface of the conveyor belt 1.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
