Description

Technical Field

[0001] The utility model relates to the technical field of belt cleaning equipment, in particular to a complete set of intelligent belt cleaning devices. Background Art

[0002] As efficient and reliable material handling equipment, belt conveyors play an indispensable role in a variety of industries, including coal chemical industry, thermal power plants, ports, and mining. They are core equipment for the continuous transportation of ore, coal, and other materials from the mining surface to the processing plant. In the coal chemical industry, belt conveyors are responsible for efficiently and continuously transporting raw materials such as coal and coke from storage areas to processing equipment, ensuring a smooth and efficient production process. They are also key equipment for coal transportation, transporting large quantities of coal directly from coal storage yards to boiler rooms, ensuring stable boiler operation and continuous power supply.

[0003] However, in the field of coal chemical industry, after conveying, the surface of the belt conveyor is usually covered with a lot of logistics residues such as coal slag, which causes the belt to spill along the line during operation, causing pollution of the production environment and waste of conveyed products. In this regard, a mechanical single cleaner is generally used to clean the belt, but the cleaner does not have the functions of automatic spraying, scraping mud, squeezing and draining, and wiping. Over time, the belt surface is prone to scaling, which damages the belt and is not easy to clean. Summary of the Invention

[0043] The working principle and specific process of this complete set of intelligent belt cleaning device:

[0044] The wheel sensor is a permanent magnetic induction switch, which includes a static magnetic switch and a dynamic control magnet. It uses the magnetic principle. When the belt runs, the sensor wheel rotates. After the static magnetic switch detects the dynamic magnet, the internal switch is actuated and the pulse signal is fed back to the electronic control host. Under the action of the host controller, a control instruction is sent to the water supplier of the cleaning device, driving the electric actuator to rotate the valve to open the passage for water supply.

[0045] Clean water with a pressure of ≥0.25Mpa enters the annular sprayer through various pipelines, and the belt is sprayed at an appropriate wide angle. The softened material on the belt surface is intercepted and scraped off by the T-type centrifugal scraper cleaner. The belt pressing roller fits tightly with the double cleaners, squeezing out most of the water slurry. Then the remaining water on the belt surface is wiped off by the silicon nitride elastic cleaner. All the removed sticky material slurry falls into the first funnel and is smoothly discharged into the ditch or sewage pipe along the pipeline under the flushing and flow assistance of the annular sprayer at the bottom of the box.

[0046] Compared with the prior art, the beneficial effects of the present invention are:

In addition, it develops a control host for various electric valves that can adapt to AC127 / DC12 / DC24V voltage to ensure that the signal is not lost and the control command is not interrupted. The material is cleaned during the return operation of the conveyor belt, and the belt chain is used for synchronous start / stop to completely remove the material from the source of the belt.

[0048] This complete set of intelligent belt cleaning devices, through the setting of cleaning devices, annular sprayers and electric ball valve water supply components, can flush and scrape the belt, effectively prevent material from spilling along the belt line, avoid polluting the production environment and wasting the conveyed products, avoid high-temperature fire caused by friction of materials on the return belt, eliminate frequent manual adjustments of the belt cleaner, reduce frequent manual cleaning, reduce workers' labor intensity, and improve employee personal safety and equipment operation safety.

[0049] This complete set of intelligent belt cleaning devices, through the setting of secondary spray washing components and cleaning and drying components, can perform secondary flushing and drying cleaning on the belt, so that the belt will not be overly wet, so that the subsequent conveying materials of the belt will not accumulate too much coal slag and other logistics residues, which is convenient for long-term circulation cleaning and other operations of the belt.

[0093] Specifically, during use, since the belt needs to be cleaned from below, in order to increase the spray pressure of the cleaning water, an ejector 9 is provided, and one end of the water inlet pipe 901 is connected to the cleaning nozzle 801, so that water enters the water tank 904 from the water inlet pipe 901, and the driving water wheel teeth 905 are electrically driven by a high-speed motor, so that the driven water wheel teeth 906 are driven to rotate at high speed, which can quickly transport the water in the water tank 904 and spray it out through the water outlet pipe 903 to clean the belt.

[0094] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 6

[0095] See also Figure 2 、 7 and Figure 8 Based on the above embodiment, the belt complete intelligent cleaning device has a secondary spraying assembly 4 provided below the belt conveyor 1. The secondary spraying assembly 4 includes a strip plate 404, a magnetic seat 405, a sleeve 406, a connecting pipe 407, a secondary water washing nozzle 408, an adjusting bolt 409, a rear seat 410, a pull bar 411, a first bearing 412, a baffle 413, a baffle 414, a half-tooth gear 415, and a baffle ring 416.

[0096] There are two sleeves 406, and they are connected as one through a connecting pipe 407 in the middle. The magnetic seat 405 is fixed at one end of the strip 404 and is magnetically connected to the two sleeves 406. The rear seat 410 is fixed at the other end of the strip 404. Through the magnetic connection between the sleeve 406 and the magnetic seat 405, the sleeve 406 and the connecting pipe 407 can be rotated on the magnetic seat 405, and the sleeve 406 can be temporarily positioned at any position after rotating to any angle.

[0097] One end of the secondary water washing nozzle 408 is connected to the sleeve 406, and the other end is rotatably connected to the rear seat 410. The nozzle of the secondary water washing nozzle 408 is set in the direction of the belt. When the sleeve 406 is rotated to any angle on the magnetic seat 405, the secondary water washing nozzle 408 is also rotated and temporarily positioned, thereby changing the spray angle toward the belt.

[0098] A retaining ring 416 is integrally connected to the inner wall of the connecting pipe 407. Baffles 414 are located on both sides of the retaining ring 416 and are arranged obliquely symmetrically. A half-toothed gear 415 is fixed to the top of the baffle 414 and is rotatably connected to the retaining ring 416. A retaining bar 413 is also fixed to the inner wall of the connecting pipe 407 and blocks the bottom end of the baffle 414.

[0099] The pull rod 411 is meshed with the two half-tooth gears 415. The first bearing 412 is fixed to the top of the pull rod 411. One end of the adjusting bolt 409 is fixed in the first bearing 412, and the other end passes through the connecting pipe 407. The two are kept in a sealed threaded connection.

[0100] When the pull bar 411 moves up and down, it drives the two half-tooth gears 415 to rotate, so that the baffles 414 on both sides of the baffle ring 416 move away from or closer to each other at the same time.

[0101] Furthermore, in this embodiment, the secondary spray washing assembly 4 also includes a second funnel 401, a second conveying pipe 402 and a second connecting plate 403; the strip plate 404 is fixed to the frame of the belt conveyor 1 through the second connecting plate 403, and the second funnel 401 is fixed to the front and rear ends of the strip plate 404 and is fixedly connected to the second conveying pipe 402.

[0102] Furthermore, it should be pointed out that a recovery tank 6 is provided below the first delivery pipe 202 and the second delivery pipe 402 , and a filter screen 601 is fixedly installed on the top of the recovery tank 6 .

[0103] Specifically, when in use, by rotating the adjusting bolt 409, the adjusting bolt 409 moves up and down in the connecting pipe 407, thereby driving the pull rod 411 to move up and down, and then the pull rod 411 drives the two half-tooth gears 415 to rotate, so that the baffles 414 on both sides of the baffle ring 416 move away from or close to each other at the same time, and finally the baffle 414 can not block the through hole in the baffle ring 416, or partially block the through hole, so as to control the amount of water entering the secondary water washing nozzle 408.

[0104] One end of the sleeve 406 is connected to the main water inlet pipe, and the total water inlet volume is not adjusted. When the through hole is partially blocked, the water pressure entering the secondary water washing nozzle 408 can be increased, so that the water column sprayed by the secondary water washing nozzle 408 is larger.

[0105] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 7

[0106] See also Figure 2 、 9 and Figure 10 On the basis of the above embodiment, the belt complete intelligent cleaning device is provided with a cleaning and drying assembly 5 below the belt conveyor 1. The cleaning and drying assembly 5 includes a return box 501, a side plate 502, a belt passage 503, a return air duct 504, a tapered flow tube 505, a fan 506, a heating wire 507, an air guide plate 508, a ring broom 509, a gear ring 510, a second bearing 511, a driving gear 512 and a driving motor 513.

[0107] The top of the return box 501 is fixed on the frame of the belt conveyor 1, and the side panels 502 are fixed on the left and right sides of the return box 501, thereby forming a belt passage 503, which is used to place the belt.

[0108] The fan 506, the heating wire 507 and the air guide plate 508 are fixedly installed on the top of the inner portion of the return box 501. The fan 506 generates hot air through the heating wire 507, and the hot air is circulated in the return air duct 504 through the air guide plate 508.

[0109] There are several conical flow tubes 505 fixed on the outer wall of the lower half of the circular box 501, and their bottoms are connected to the circular air duct 504, so that hot air can be blown toward the belt through the conical flow tubes 505. The conical flow tubes 505 can gather hot air to form a hot air flow, and through the setting of the inner bend at the end, the hot air flow can accelerate the flow rate of the hot air flow after passing through the middle end, so that the hot air flow can be ejected more quickly from the top of the conical flow tube 505, thereby acting on the belt surface.

[0110] The annular broom 509 is located on the periphery of the conical flow tube 505, and the bottom end of the annular broom 509 is rotatably connected to the outer wall of the lower half of the back-shaped box 501 by a second bearing 511;

[0111] The gear ring 510 is fixed to the outer wall of the bottom end of the annular broom 509 and is meshed with the driving gear 512. The driving motor 513 drives the driving gear 512 and is also fixed to the outer wall of the lower half of the letter box 501.

[0112] By setting the annular broom 509, when it rotates, it can clean the belt surface, and because it is set as an annular structure, the belt surface can be cleaned twice.

[0113] Specifically, when in use, after the belt is cleaned twice, the driving motor 513 drives the driving gear 512, and the driving gear 512 drives the annular broom 509 to rotate through the gear ring 510 to clean the belt surface and remove the small water droplets remaining on the belt surface;

[0114] At the same time, the fan 506 generates hot air through the heating wire 507, and the hot air is circulated in the return air duct 504 through the air guide plate 508. The hot air is gathered by the conical flow pipe 505 to form a hot air flow, so that the hot air flow is ejected from the top of the conical flow pipe 505 relatively quickly, thereby acting on the belt surface and roughly drying the belt, thereby preventing the belt from being too wet, and thus preventing a large amount of material from remaining on the belt during conveying;

[0115] Since the annular broom 509 is an annular structure, after removing small water droplets on the belt surface and then drying it, the dried belt surface can be cleaned again, further improving the cleanliness of the belt.

[0116] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.
