Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to a tubular belt conveyor with a cleaning function. Background Technology

[0002] Tubular belt conveyors are advanced continuous conveying equipment that use a conveyor belt rolled into a cylindrical shape to enclose materials for sealed conveying. The conveyor belt has a tail forming section that is gradually rolled into a cylindrical shape by rollers during the generation stage, and a head unfolding section that is gradually flattened by rollers from a cylindrical shape. The tubular belt conveyor is divided into upper and lower sections. The upper section is the carrying section, responsible for carrying materials and transporting them from the starting point to the end point. In the conveyor, the upper section is rolled into a ring to completely enclose the materials for sealed transport. The lower section is the return section. After the materials are transported, the empty return section needs to return to the starting point to begin the next loading and transport. The switching between the upper and lower sections causes the belt to flip inside and out. The inner wall of the carrying section becomes the outer wall of the return section. This process produces residual materials on the inner wall of the carrying section, which fall into the road when the belt flips to become the outer wall of the return section, causing environmental pollution. The outer wall of the return section becomes the inner wall of the carrying section. Environmental impurities on the outer wall of the return section will contaminate the transported materials during the flipping process. Therefore, a cleaning function needs to be added to the tubular belt conveyor.

[0003] Existing tubular belt conveyors with cleaning functions mostly clean by using cleaning brushes or scrapers at the transition between the upper and lower sections. However, the conveyor belt is curved and in a state of transition between tubular and flat. The cleaning brush or scraper needs to apply pressure to contact the curved surface, which will cause wear on the surface of the conveyor belt and the cleaning body. Rinsing can solve the problem of cleaning dead corners by adjusting the angle, but the rinsing method faces the problem of water seepage at the conveyor belt joint, which causes the steel rope core to rust and the fabric core to become moldy. In addition, the splashed wastewater during the rinsing process may contaminate the materials being loaded and unloaded.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0005] This invention provides a tubular belt conveyor with a cleaning function, the purpose of which is to solve the problem of cleaning dead zones caused by the difficulty in fitting the real-time changing curved surface of the conveyor belt.

[0016] Furthermore, a connecting frame is movably slidably connected inside the inclined hole, and the extrusion roller is rotatably connected inside the connecting frame.

[0024] Beneficial effects

[0025] The present invention has the following beneficial effects:

[0026] This tubular belt conveyor with cleaning function replaces brushing or scraping with rinsing, allowing water jets to contact the conveyor belt for thorough cleaning without dead angles. A wiping mechanism drives absorbent cotton to circulate through contact with the conveyor belt, absorbing water, rinsing off residual stains, and squeezing out water, effectively drying the conveyor belt and preventing water seepage that could cause corrosion of the steel rope core and mold growth on the fabric core. Simultaneously, a spring-driven multi-segment movable plate refines the spring's force response, allowing the silicone columns to better conform to the conveyor belt's curvature. The silicone columns, while rigid, can deform and stretch within a small range, preventing wear on the conveyor belt. The deformation of the silicone columns further adapts to the conveyor belt's curvature, and the expansion and compression of the absorbent cotton ensures even contact with the conveyor belt, improving drying efficiency. Furthermore, the absorbent cotton achieves drying and absorbent of impurities in the water through mere contact, eliminating the need for uniform force application required by cleaning brushes or scrapers. This solves the problem of uneven force application for the constantly changing curvature of tubular conveyor belts.

[0027] This tubular belt conveyor with cleaning function uses absorbent cotton fitted between silicone pillars, a convex ring, and a squeezing roller. The convex ring on the motor-driven rotating shaft maintains the same transmission speed as the conveyor belt, reducing wear between the absorbent cotton and the conveyor belt. As the silicone pillars move up and down with the spring to change the tightness of the absorbent cotton, the third flushing head always pushes the absorbent cotton towards the convex ring, increasing the friction between the absorbent cotton and the convex ring. The convex ring itself also increases the friction between itself and the absorbent cotton, allowing the absorbent cotton to rotate more stably and cycle through water absorption, rinsing, and squeezing, thus improving the cleaning effect on the conveyor belt.

[0028] This tubular belt conveyor with cleaning function uses the driving force of a motor to rotate the second shaft and the convex ring through a mud removal mechanism. At the same time, the second flushing head can reciprocate, which avoids the motor being installed in the isolation box for long-term water flushing, thus improving service life and facilitating maintenance. During the transmission process, it also drives the scraper to reciprocate to scrape the inner wall of the isolation box, preventing impurities from sticking to the wall, keeping the isolation box clean, and improving the cleaning effect.

[0029] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0049] Please see Figures 1-15 This invention provides a technical solution: a tubular belt conveyor with cleaning function, such as... Figures 1-3As shown, the machine includes a body 1 and a feed port 101 and a discharge port 102 provided on the body 1. A conveyor belt 103 is provided between the feed port 101 and the discharge port 102. An isolation box 2 is provided at one end of the conveyor belt 103 near the discharge port 102. The isolation box 2 is fixedly connected to the body 1. A water tank 3 is fixedly connected to the body 1. A rinsing mechanism 4 is provided at the output end of the water tank 3. A drying mechanism 5 is provided on the body 1. A mud removal mechanism 6 for transmission and scraping the inner wall of the isolation box 2 is provided between the drying mechanism 5 and the rinsing mechanism 4. The isolation box 2 has two through holes along the transmission direction of the conveyor belt 103. The conveyor belt 103 passes through the opposite ends of the through holes, and there is a gap between the conveyor belt 103 and the through holes.

[0050] The body 1 is the steel structure of the tubular belt conveyor shell, and also includes existing tubular belt conveyor structures such as motors. Its specific structure and working principle are all existing technologies. The water tank 3 contains a water pump. During the rinsing process, the water pump draws clean water from the water tank 3 and transmits it to the rinsing head through the water pipe. The bottom of the isolation box 2 has a water outlet for discharging sewage. The water outlet is connected to a sewage processor. The sewage processor is external and is a common structure for water circulation, which is not shown in the attached diagram. After the sewage is treated, it can be fed into the water tank 3 to achieve water circulation.

[0051] like Figures 4-8 As shown, an installation bracket 401 is fixedly connected to the inner wall of the isolation box 2. The rinsing mechanism 4 includes a first rinsing head 402 and a second rinsing head 403 mounted on the installation bracket 401. The drying mechanism 5 includes several springs 506. Every two springs 506 are rotatably connected to a movable plate 508 via a rotating joint 507. Adjacent movable plates 508 are rotatably connected to each other. Silicone pillars 509 are fixedly connected to several movable plates 508.

[0052] The silicone pillar 509 is made of hard silicone, which has a small range of deformation and tensile properties. It also has hardness to bring the absorbent cotton 514 into contact with the bottom surface of the conveyor belt 103. The hardness range is Shore A20° to Shore D60°+. The first flushing head 402 is aligned with the bottom of the conveyor belt 103. The flushing force varies with different tilt angles. The specific tilt angle can be determined according to the properties of the material attached to the conveyor belt 103. The part of the silicone pillar 509 above the movable plate 508 is fixedly connected to the movable plate 508, while the part between the two movable plates 508 is not fixedly connected to facilitate deformation with the angle between the two movable plates 508.

[0053] The first flushing head 402 is a structure in which a water spray nozzle is fixed with a rotating shaft. The rotating shaft has a threaded groove, and the rotating shaft is connected to the mounting bracket 401 by a nut.

[0054] Before cleaning, the angle of the first rinsing head 402 is adjusted according to the viscosity of the material. The adjustment method is to loosen the nut between the rotating shaft of the first rinsing head 402 and the mounting bracket 401, rotate the first rinsing head 402 to the required angle, and then tighten the nut. During the cleaning process, the restoring force of the spring 506 drives the two ends of the movable plate 508 to approach the conveyor belt 103. The two adjacent movable plates 508 rotate according to the curvature of the bottom surface of the conveyor belt 103. The silicone column 509 deforms between the movable plate 508 and the conveyor belt 103 following the change of the movable plate 508, so that the top surface of the silicone column 509 fits more closely with the bottom surface of the conveyor belt 103. The silicone column 509 drives the absorbent cotton 514 to fully contact the surface of the conveyor belt 103 and absorb water through the curvature similar to the bottom surface of the conveyor belt 103.

[0055] An installation frame 501 is fixedly connected to the outer wall of the isolation box 2 at the end away from the discharge port 102. A motor 502 is fixedly installed on one side of the installation frame 501. A rotating shaft 503 is fixedly connected to the output end of the motor 502. Several protruding rings 504 are evenly fixedly connected to the rotating shaft 503 along the axial direction. A third flushing head 505 is fixedly connected inside the installation frame 501, and the third flushing head 505 faces the rotating shaft 503. An oblique hole is opened below the silicone column 509 in the isolation box 2. An extrusion roller 513 is installed in the oblique hole. Water-absorbing cotton 514 is sleeved on the silicone column 509, the protruding rings 504 and the extrusion roller 513. The water-absorbing cotton 514 is in contact with the conveyor belt 103. A connecting frame 512 is slidably connected in the oblique hole. The pressure roller 513 is rotatably connected inside the connecting frame 512, and a second spring 510 and a square telescopic rod 511 are provided between the connecting frame 512 and the top wall of the inclined hole. The top ends of the second spring 510 and the square telescopic rod 511 are fixedly connected to the isolation box 2, and the bottom ends of the second spring 510 and the square telescopic rod 511 are fixedly connected to the connecting frame 512. There are two square telescopic rods 511, which are located at the top two ends of the connecting frame 512. The second spring 510 is located in the middle between the two square telescopic rods 511. The inclined hole is inclined towards the bottom of the inner wall of the isolation box 2. The mounting frame 501 has the same inclination angle as the inclined hole. The absorbent cotton 514 is located between the convex ring 504 and the third flushing head 505.

[0056] The absorbent cotton 514 is made of industrial-grade composite microfiber absorbent cotton. The motor 502 is a servo motor, and its encoder is fixed at the end of the motor 502 away from the rotating shaft 503. The controller is fixed in the control box on the machine body 1 for controlling the entire tubular belt conveyor. Its specific structure and working principle are existing technologies. The motor 502 drives the rotating shaft 503 to maintain the same speed as the conveyor belt 103. The length of the absorbent cotton 514 is the length of one turn of the silicone column 509, the convex ring 504 and the extrusion roller 513 when the spring 506 and the spring 510 are stretched to their longest length. The square telescopic rod 511 is a structure in which a square rod is inserted inside a square tube and the outer wall of the square rod abuts against the inner wall of the square tube.

[0057] When spring 506 and spring 510 are not fully extended, the friction between the absorbent cotton 514 and the conveyor belt 103 causes the conveyor belt 103 to rotate, and the motor 502 drives the rotating shaft 503 to rotate. The convex ring 504 rotates with the rotating shaft 503. The third flushing head 505 flushes the absorbent cotton 514 that has just come into contact with the conveyor belt 103, while simultaneously pushing the absorbent cotton 514 towards the convex ring 504, increasing the friction between the absorbent cotton 514 and the convex ring 504, thus increasing the absorption rate. As the convex ring 504 rotates, the water absorbent cotton 514 is transferred to the area below the squeezing roller 513. The restoring force of the second spring 510 causes the connecting frame 512 to move downwards, and the square telescopic rod 511 extends. The square shape restricts the squeezing roller 513 to only move in a straight line up and down. The squeezing roller 513 moves downwards with the connecting frame 512 to squeeze the rinsed water absorbent cotton 514. The squeezing roller 513 can rotate to reduce friction so that the water absorbent cotton 514 can be transferred normally. The oblique hole setting can drain the squeezed water to the bottom of the isolation box 2.

[0058] like Figure 9 As shown, the first flushing head 402 is rotatably connected to the mounting bracket 401, and a support bracket 405 is fixedly connected to the mounting bracket 401. The second flushing head 403 is set on the support bracket 405. The first flushing head 402 and the second flushing head 403 are vertically distributed, and the second flushing head 403 is located below the first flushing head 402. The water tank 3 is connected to the first flushing head 402, the second flushing head 403 and the third flushing head 505 through water pipes. A rotating shaft 404 is vertically rotatably connected to the inner wall of the support bracket 405. The second flushing head 403 is fixedly connected to the rotating shaft 404. A gear 406 is keyed to the bottom of the outer wall of the rotating shaft 404.

[0059] The support frame 405 is a structure with a square frame on top of a horizontal plate, and vertical plates are inserted and fixed at both ends of the horizontal plate. The second flushing head 403 is a structure with a flushing head fixed on a rotating drum. The rotating drum is fixedly connected to the rotating shaft 404, and the rotating shaft 404 is rotatably connected between the top wall of the square frame and the horizontal plate.

[0060] like Figure 10 As shown, the mud removal mechanism 6 includes a mounting part 601 fixed to the outer wall of the isolation box 2 near one end of the inclined hole. The inner wall of the mounting part 601 is rotatably connected to a rotating shaft 602. The rotating shaft 602 and the rotating shaft 503 are rotatably connected through a bevel gear 603. A worm gear 605 is fixedly connected to the lower position of the rotating shaft 602. The outer wall of the isolation box 2 is fixedly connected to a mounting part 604 located below the mounting part 601. The inner wall of the mounting part 604 is rotatably connected to a threaded cylinder 607. The outer wall of the threaded cylinder 607 is fixedly connected to a worm wheel 606, which meshes with the worm gear 605.

[0061] There are two bevel gears 603. One is keyed to the third shaft 602 and the other is keyed to the second shaft 503. The two bevel gears 603 mesh. When the second shaft 503 rotates under the drive of the motor 502, the power is transmitted to the third shaft 602 through the bevel gear 603. The worm 605 rotates with the third shaft 602, and the worm wheel 606 rotates with the worm 605.

[0062] like Figure 10 , Figures 12-13 As shown, the inner wall of the threaded cylinder 607 is provided with a planar thread, and a slider 608 is fitted and slidably connected in the planar thread. A fixing ring 609 is fixedly connected to the top of the slider 608. A sliding rod 610 is fixedly connected to the inner wall of the fixing ring 609. Two limiting members 611 are slidably connected on the sliding rod 610. The outer wall of the limiting member 611 is fixedly connected to the isolation box 2.

[0063] The threaded cylinder 607 rotates with the worm gear 606. The limiting member 611 limits the height of the slide rod 610. The slide rod 610, the fixing ring 609 and the slider 608 on it cannot rotate with the threaded cylinder 607. The slider 608 slides in the planar thread inside the threaded cylinder 607 and achieves left and right reciprocating motion through the trajectory of the planar thread. The fixing ring 609 and the slide rod 610 follow the left and right reciprocating motion.

[0064] A connecting rod 612 is fixedly connected to the slide rod 610. A square hole for sliding the connecting rod 612 is provided on the isolation box 2. A mounting plate 613 is fixedly connected to the end of the connecting rod 612 away from the slide rod 610. A rack 614 is fixedly connected to the mounting plate 613. The rack 614 meshes with a gear 406. A protruding hole is provided on the support frame 405. The mounting plate 613 is fitted and slidably connected in the protruding hole. There are two mounting plates 613. The two mounting plates 613 are symmetrically distributed with the gear 406 as the base point. Two rotating shafts 616 are rotatably connected to the support frame 405. The two rotating shafts 616 are symmetrically distributed with the gear 406 as the base point. A gear 615 is keyed to the lower position of the rotating shaft 616. The gear 615 meshes with the rack 614. A mud scraping assembly is provided on the rotating shaft 616.

[0065] The four pivots 616 are rotatably connected to the top two ends of the horizontal plate of the support frame 405, and the mounting plate 613 is embedded and slidably connected to the vertical plate of the support frame 405.

[0066] The connecting rod 612 moves with the sliding rod 610, the mounting plate 613 moves with the connecting rod 612, the rack 614 moves with the mounting plate 613, and the gear 1 406 and gear 2 615 reciprocate clockwise and counterclockwise by meshing with the rack 614. The rotating shaft 1 404 rotates with the gear 1 406, and the second flushing head 403 reciprocates left and right with the rotating shaft 1 404, dynamically flushing the inner wall of the isolation box 2 and increasing the flushing area.

[0067] like Figures 14-16 As shown, the sludge scraping assembly includes a slide rail 617 fixedly connected to a rotating shaft 616. The slide rail 617 is provided with two fixing blocks 620. One fixing block 620 is fixedly connected to the slide rail 617, and the other fixing block 620 is embedded and slides within the slide rail 617. A connecting plate 618 is fixedly connected to the other fixing block 620. A scraper 619 is fixedly connected to the end of the connecting plate 618 away from the slide rail 617. The scraper 619 contacts the inner wall of the isolation box 2. A spring 621 is fixedly connected between the two fixing blocks 620.

[0068] The scraper 619 is made of silicone, the same material as the silicone column 509.

[0069] The rotating shaft 616 follows the gear 615 to rotate, the slide rail 617 follows the rotating shaft 616 to rotate, the fixed block 620 follows the slide rail 617 to rotate, the connecting plate 618 and the scraper 619 follow the fixed block 620 fixed to the connecting plate 618 to rotate. Under the return of the spring 621, the fixed block 620 fixed to the connecting plate 618 approaches the inner wall of the isolation box 2, and the connecting plate 618 moves with the fixed block 620, so that the scraper 619 always contacts the inner wall of the isolation box 2 during the rotation, so as to achieve scraping cleaning and avoid impurities sticking to the wall.

[0070] Working principle: Before cleaning, the angle of the first rinsing head 402 is adjusted according to the viscosity of the material. The adjustment method is to loosen the nut between the rotating shaft of the first rinsing head 402 and the mounting bracket 401, rotate the first rinsing head 402 to the required angle, and then tighten the nut. During the cleaning process, the restoring force of the spring 506 drives the two ends of the movable plate 508 to approach the conveyor belt 103. The two adjacent movable plates 508 rotate according to the curvature of the bottom surface of the conveyor belt 103. The silicone column 509 deforms between the movable plate 508 and the conveyor belt 103 following the change of the movable plate 508, so that the top surface of the silicone column 509 fits more closely with the bottom surface of the conveyor belt 103. The silicone column 509 drives the absorbent cotton 514 to fully contact the surface of the conveyor belt 103 and absorb water through the curvature similar to the bottom surface of the conveyor belt 103.

[0071] When spring 506 and spring 510 are not fully extended, the friction between the absorbent cotton 514 and the conveyor belt 103 causes the conveyor belt 103 to rotate, and the motor 502 drives the rotating shaft 503 to rotate. The convex ring 504 rotates with the rotating shaft 503. The third flushing head 505 flushes the absorbent cotton 514 that has just come into contact with the conveyor belt 103, while simultaneously pushing the absorbent cotton 514 towards the convex ring 504, increasing the friction between the absorbent cotton 514 and the convex ring 504, thus increasing the absorption rate. As the convex ring 504 rotates, the water absorbent cotton 514 is transferred to the area below the squeezing roller 513. The restoring force of the second spring 510 causes the connecting frame 512 to move downwards, and the square telescopic rod 511 extends. The square shape restricts the squeezing roller 513 to only move in a straight line up and down. The squeezing roller 513 moves downwards with the connecting frame 512 to squeeze the rinsed water absorbent cotton 514. The squeezing roller 513 can rotate to reduce friction so that the water absorbent cotton 514 can be transferred normally. The oblique hole setting can drain the squeezed water to the bottom of the isolation box 2.

[0072] When the second rotating shaft 503 rotates under the drive of the motor 502, it transmits power to the third rotating shaft 602 through the bevel gear 603. The worm 605 rotates with the third rotating shaft 602, the worm wheel 606 rotates with the worm 605, and the threaded cylinder 607 rotates with the worm wheel 606. The limiting member 611 limits the height of the slide rod 610. The slide rod 610, its fixing ring 609, and the slider 608 cannot rotate with the threaded cylinder 607. The slider 608 slides within the planar thread inside the threaded cylinder 607, achieving left and right reciprocating motion through the trajectory of the planar thread. The motion is such that the fixed ring 609 and the slide rod 610 reciprocate left and right, the connecting rod 612 moves with the slide rod 610, the mounting plate 613 moves with the connecting rod 612, the rack 614 moves with the mounting plate 613, the gear 1 406 and the gear 2 615 reciprocate clockwise and counterclockwise by meshing with the rack 614, the rotating shaft 1 404 rotates with the gear 1 406, and the second flushing head 403 reciprocates left and right with the rotating shaft 1 404, dynamically flushing the inner wall of the isolation box 2 and increasing the flushing area.

[0073] The rotating shaft 616 follows the gear 615 to rotate, the slide rail 617 follows the rotating shaft 616 to rotate, the fixed block 620 follows the slide rail 617 to rotate, the connecting plate 618 and the scraper 619 follow the fixed block 620 fixed to the connecting plate 618 to rotate. Under the return of the spring 621, the fixed block 620 fixed to the connecting plate 618 approaches the inner wall of the isolation box 2, and the connecting plate 618 moves with the fixed block 620, so that the scraper 619 always contacts the inner wall of the isolation box 2 during the rotation, so as to achieve scraping cleaning and avoid impurities sticking to the wall.
