Description

Technical Field

[0001] The utility model belongs to the technical field of coal feeders, in particular to a method and a device for processing coal feeder inlet blockage. Background Art

[0002] When comprehensive utilization power plants generate electricity, cheap comprehensive utilization mixed coal is used instead of expensive clean coal as fuel to reduce production costs. The mixed coal process used in power boiler production is as follows: an overhead crane is used to grab the mixed coal from the coal yard and bring it to the coal storage bin. The coal is then brought to the belt by the coal feeder equipment under the coal storage bin, and then transported to the mixed coal bin by the belt. The coal in the mixed coal bin passes through the coal feeder equipment and enters the crusher for crushing. The qualified mixed coal particles after crushing are used to power power boilers.

[0003] The coal feeder has high operating efficiency. During the continuous coal feeding, blockage is inevitable due to the continuous flow of coal particles. The existing coal feeder inlet blockage detection method and equipment are single in function and can often only detect the blockage but not clear it. Once the blockage is detected, the staff needs to manually operate to clear it, which increases the workload and prolongs the blockage time, significantly reduces the coal feeding efficiency, and even causes damage to the detection equipment due to long-term blockage. Therefore, it is necessary to develop a method for processing the blockage of the coal feeder inlet and related equipment to solve the existing problem. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a method and device for processing coal feeder inlet blockage, which has the advantages of real-time detection and automatic unblocking.

[0005] Among them, with the cooperation of the clockwork spring, the limit sleeve and the dredging frame can rotate relative to the transmission component as a whole when blockage occurs in the coal feeder inlet, ensuring that the drive motor can still drive the transmission component to operate normally when blockage occurs, and the drive motor will not be damaged due to a sudden surge in load due to blockage.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a method for treating a coal feeder inlet blockage, comprising the following steps:

[0007] S1. Install the device at the coal feeder inlet with the second bearing and the first bearing in place, ensuring that the drive motor is located outside the coal feeder inlet and the dredging frame is located inside the coal feeder inlet;

[0014] S8. Due to the relative sliding of the transmission sleeve with respect to the surface of the linkage sleeve, the dredging frame can be driven to slide left and right relative to the linkage sleeve and the transmission assembly under the connection between the limit sleeve and the spring, so that the position of the dredging groove can be changed, thereby achieving the purpose of vibrating the blocked coal blocks and clearing the blockage.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figures 1 to 9 As shown, the utility model provides a method for treating the blockage of the coal machine inlet, and the following operating steps are performed:

[0041] S1. Install the device to the coal feeder inlet with the cooperation of the second bearing 32 and the first bearing 22, and ensure that the drive motor 1 is located outside the coal feeder inlet, and the dredging frame 5 is located inside the coal feeder inlet;

[0042] S2. While feeding, the drive motor 1 is turned on in cooperation with the controller 7;

[0043] S3. Since the operation of the drive motor 1 can drive the transmission rod 21 to rotate, the rotation of the transmission rod 21 can be driven by the second linkage assembly 44, the first linkage assembly 41, the clockwork spring 43 and the limit sleeve 42 to drive the dredging frame 5 movement;

[0044] S4. Due to the movement of the dredge frame 5, the coal entering the entrance is continuously stirred in cooperation with several dredge grooves 6 on its surface to avoid accumulation and blockage;

[0045] S5. If the inlet valve is clogged, the dredging frame 5 will be unable to rotate. However, due to the elastic force of the clockwork spring 43, the drive motor 1 can still drive the second linkage assembly 44 to rotate through the transmission assembly 2, thereby causing relative rotation between the first linkage assembly 41 and the limit sleeve 42 and the second linkage assembly 44. Due to the configuration of the clockwork spring 43, the limit sleeve 42 and the dredging frame 5 can rotate relative to the transmission assembly 2 when a blockage occurs at the coal feeder inlet. This ensures that the drive motor 1 can still drive the transmission assembly 2 normally in the event of a blockage, and prevents damage to the drive motor 1 caused by a sudden increase in load due to a blockage.

[0046] S6. Since the relative rotation between the first linkage assembly 41 and the limit sleeve 42 can trigger the displacement sensor between the two, the operation of the sensor can stop the feeding port; due to the setting of the clockwork spring 43, when a blockage occurs, the limit sleeve 42 and the transmission sleeve 411 can rotate relative to each other, thereby triggering the displacement sensor between the two, thereby stopping the feeding and exacerbating the blockage;

[0047] S7. At the same time, due to the relative rotation between the first linkage assembly 41 and the second linkage assembly 44, the two can slide relative to each other in cooperation with the linkage guide groove 442 and the linkage ball 413, and under the restriction of the limit cavity 33, the positioning spring 35 is compressed by the transmission sleeve 411 and the positioning slider 34 to increase its elastic recovery performance;

[0048] S8. Due to the relative sliding of the transmission sleeve 411 with respect to the surface of the linkage sleeve 441, the dredging frame 5 can be driven to slide left and right relative to the linkage sleeve 441 and the transmission assembly 2 under the connection action of the limit sleeve 42 and the clockwork spring 43, so that the position of the dredging groove 6 can be changed, thereby achieving the purpose of vibrating the blocked coal blocks and clearing the blockage.

[0051] like Figure 2 As shown, the outside of the transmission rod 21 is sleeved with a positioning component 3 and a second transmission component 4, both of which are located inside the coal feeder inlet. The outside of the second transmission component 4 is fixedly sleeved with a dredging frame 5, and the inside of the dredging frame 5 is provided with a number of evenly distributed dredging grooves 6, and the outer surface of the dredging frame 5 and the inner wall of the dredging groove 6 are smooth.

[0052] like Figure 3 As shown, the positioning assembly 3 includes a positioning sleeve 31 movably sleeved on the outer surface of the transmission rod 21, and the outside of the positioning sleeve 31 is fixedly sleeved with a second bearing 32, and the second bearing 32 is fixedly sleeved inside the inlet structure of the coal feeder; due to the setting of the first bearing 22, the transmission rod 21 can rotate smoothly with the cooperation of the second bearing 32, and drive the second transmission assembly 4 and the external dredging frame 5 to move.

[0053] like Figure 3 and Figure 4As shown, a limiting cavity 33 is provided inside the positioning sleeve 31, and the cross-section of the limiting cavity 33 is a "convex" shape. The inner diameter of the limiting cavity 33 on the side close to the second transmission component 4 is smaller than the inner diameter on the side away from the second transmission component 4, and the inner wall of the limiting cavity 33 is smooth; due to the setting of the limiting cavity 33, the positioning slider 34 is ensured to be able to move back and forth inside it, thereby achieving the effect of compressing the positioning spring 35, and at the same time, under the elastic recovery action of the positioning spring 35, the limiting sleeve 42 and the dredging frame 5 as a whole can be reset after the blockage is cleared, so as to prepare for the next blockage.

[0054] like Figure 4 As shown, a positioning slider 34 is movably provided between the limiting cavity 33 and the transmission rod 21, and one side of the positioning slider 34 is connected to the second transmission assembly 4. A positioning spring 35 is also provided inside the limiting cavity 33 and is located on the other side of the positioning slider 34. The two ends of the positioning spring 35 respectively abut against the inner cavity of the limiting cavity 33 and one side of the positioning slider 34; due to the setting of the positioning slider 34, the recovery action of the positioning spring 35 can make the dredging frame 5 move laterally under the cooperation of the linkage ball 413 and the linkage guide groove 442, thereby achieving the effect of dredging the blockage, and it can also avoid it from escaping from the limiting cavity 33 under the restriction of the limiting cavity 33.

[0055] like Figure 3 As shown, the second transmission component 4 includes a first linkage component 41 that is movably sleeved between the transmission rod 21 and the positioning sleeve 31, and the internal movably sleeve of the first linkage component 41 is connected to the second linkage component 44, and the second linkage component 44 is fixedly sleeved on the outer surface of the transmission rod 21. The external movably sleeve of the first linkage component 41 is connected to the limiting sleeve 42, and the limiting sleeve 42 is fixedly sleeved on the inside of the dredging frame 5. The cross-section of the limiting sleeve 42 is "concave", and a clockwork spring 43 is arranged inside the limiting sleeve 42. The two ends of the clockwork spring 43 are respectively connected to the first linkage component 41 and the limiting sleeve 42; due to the setting of the limiting sleeve 42, with the cooperation of the clockwork spring 43, the first linkage component 41 can drive the dredging frame 5 to rotate when it rotates, and the two can also rotate relative to each other under the connection form of rotational connection.

[0056] like Figure 3 、 Figure 6 and Figure 7As shown, the first linkage assembly 41 includes a transmission sleeve 411 that is rotatably clamped to the inside of the limit sleeve 42, the transmission sleeve 411 is movably sleeved on the outside of the limit sleeve 42, one end of the transmission sleeve 411 extends to the inside of the positioning sleeve 31 and is fixedly connected to the limiting ring 412, the limiting ring 412 is movably sleeved in the inside of the limiting cavity 33, and the side of the limiting ring 412 is fixedly connected with a coaxial rotating snap ring 414, and the rotating snap ring 414 is movably sleeved in the inside of the positioning slider 34; due to the setting of the rotating snap ring 414, one end of the transmission sleeve 411 can slide left and right in the inside of the limit cavity 33 with the cooperation of the positioning slider 34, while ensuring that the positioning spring 35 will not be distorted and its elasticity will be reduced when the transmission sleeve 411 rotates.

[0057] like Figure 3 、 Figure 8 and Figure 9 As shown, the second linkage assembly 44 includes a linkage sleeve 441 fixedly sleeved on the outside of the transmission rod 21. The length of the linkage sleeve 441 is greater than the length of the limiting sleeve 42 and less than the length of the transmission sleeve 411. A plurality of evenly distributed linkage guide grooves 442 are provided on the outside of the linkage sleeve 441, and the inner wall of the second linkage assembly 44 is smooth.

[0058] like Figure 5 、 Figure 7 and Figure 9 As shown, the outer surface of the linkage sleeve 441 and the inner wall of the transmission sleeve 411 are smooth, and the internal movable rolling connection of the linkage guide groove 442 is equipped with a number of evenly distributed linkage balls 413, which are movably embedded in the interior of the transmission sleeve 411; due to the setting of the positioning component 3, with the cooperation of the linkage balls 413 and the linkage guide groove 442, the first linkage component 41 and the second linkage component 44 that rotate relatively can move laterally, so that the dredging frame 5 and the dredging groove 6 on its surface can avoid sliding on the blocked coal blocks, thereby achieving the effect of vibration dredging.
