Description

Technical Field

[0001] The utility model relates to the technical field of coal feeders, and more specifically to a weighing type belt coal feeder belt sticking coal cleaning device. Background Art

[0002] Weighing type belt coal feeders are needed to transport coal in thermal power plants. However, the weighing type belt coal feeder has its own sticky coal cleaning device, which has a fixed counterweight, a fixed contact distance with the belt, and a fixed cleaning force for the belt sticky coal. There are no adjustment measures during operation, and it cannot adapt to changes in coal types and changes in the dryness and wetness of the coal. As a result, a thick layer of coal adheres to the belt during the spring rainy season in the south, the alternating rains in spring and summer, and the low temperature rain in winter. The sticky coal on the belt will lead to a series of problems such as coal feeder breakage, belt deviation, and belt slippage.

[0003] Most of the current belt cleaning systems are equipped with corresponding cleaning devices, which adjust the pressure between the scraper and the belt through the cooperation of the pressure-adjusting nut and the spring, so as to achieve the cleaning of the belt. However, there are still some shortcomings in the actual use of the cleaning device. The cleaning device is generally fixed with bolts and a coal feeder, so that the position of the cleaning device cannot be adjusted. The operator can only clean the belt by adjusting the angle between the scraper and the belt, but cannot adjust the height of the scraper, so that the scraper can only have a good cleaning effect on the belt within a fixed range, so it is necessary to improve this.

[0033] When the two movable blocks 305 move toward each other along the inner surface of the round rod 1, since the two ends of the inclined rod 304 are hinged to the base 302 and the movable block 305 respectively, as the movable block 305 moves, the top of the inclined rod 304 will generate a thrust on the bottom of the base 302, pushing the base 302 to move upward with the scraper 303, and the existence of the vertical plate 301 limits the movement of the base 302. Under the action of the movable block 305 and the inclined rod 304, the height of the scraper 303 is adjusted, thereby improving the practicability and applicability of the cleaning device.

[0034] Wherein, the rotating mechanism 4 includes:

[0035] Fixed blocks 401, the number of fixed blocks 401 is two, the two fixed blocks 401 are respectively fixedly sleeved on the left and right ends of the inside of the round rod 1, the inner surfaces of the two fixed blocks 401 are movably sleeved with double-threaded rods 402, the left and right sides of the outer surface of the double-threaded rod 402 are respectively threadedly sleeved with the inner surfaces of the two movable blocks 305, and the middle part of the outer surface of the double-threaded rod 402 is movably sleeved with the inner surface of the vertical plate 301;

[0037] When the handle 403 is turned, the double-threaded rod 402 will rotate along the inner surface of the fixed block 401, so that the two movable blocks 305 threadedly sleeved with the double-threaded rod 402 will move toward each other.

[0038] Among them, the left and right sides of the bottom end of the round rod 1 are respectively provided with a slide groove 5, and a slider 6 is movably sleeved inside the slide groove 5.

[0043] When the pressure-adjusting nut 11 is rotated, the pressure-adjusting nut 11 will push the pad 12 to move along the outer surface of the screw rod 10, thereby compressing the first spring 13, and further adjusting the pressure between the cleaning device and the belt.

[0044] Circular holes 14 are respectively provided inside the left and right ends of the scraper 303 , and a clamping rod 15 is movably sleeved inside the circular hole 14 .

[0048] The working principle and use process of this utility model:

[0049] First, the operator fixes the cleaning device and the weighing type belt coal feeder and makes the scraper 303 contact with the belt, and then rotates the pressure regulating nut 11, so that the pressure regulating nut 11 pushes the pad 12 toward the rectangular block 8, so that the pad 12 compresses the first spring 13, and due to the restoring effect of the first spring 13, the rectangular block 8 will rotate with the square block 7 and the round rod 1, so that the scraper 303 and the belt are tightly fitted, and then the operator rotates the handle 403 so that the double threaded rod 402 moves along the fixed block 401. The inner surface of the round rod 1 rotates, and the two movable blocks 305 threadedly connected with the double-threaded rod 402 will move toward each other along the inner surface of the round rod 1 with the bottom end of the inclined rod 304, so that the top end of the inclined rod 304 generates a thrust on the bottom end of the base 302, pushing the base 302 to move upward with the vertical plate 301 and the scraper 303 until the scraper 303 and the belt are at an optimal contact angle, thereby realizing the adjustment of the height of the scraper 303, thereby improving the practicability and applicability of the cleaning device.

[0050] When replacing the scraper 303, the operator pulls the long rod 16, so that the long rod 16 moves with the clamping rod 15 along the outer surface of the limit rod 18 and stretches the second spring 17 until the clamping rod 15 and the round hole 14 are separated, thereby releasing the lock of the scraper 303 on the position of the clamping rod 15. The operator then takes out the scraper 303 for replacement. When the replacement is completed, the operator releases the long rod 16, so that the clamping rod 15 returns to its original position under the restoring action of the second spring 17, thereby connecting and fixing the scraper 303 and the base 302, so that the scraper 303 can be quickly replaced, so that the operator does not need to disassemble the cleaning device as a whole, thereby improving the convenience of the cleaning device.
