Description

Technical Field

[0001] This utility model relates to the field of coal chute technology, specifically a detachable coal chute. Background Technology

[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground and undergoing complex biochemical and physicochemical changes. It is one of the most abundant and widely distributed fossil fuels on Earth, and also an indispensable energy source for human production and life. Furthermore, the supply of coal is related to the stability of my country's industrial development and even the development of all aspects of society. Therefore, the security of coal supply is also the most important link in my country's energy security.

[0003] Coal chutes are used in industries such as coal, ports, thermal power, coal transfer and storage stations, coal washing plants, and coal-fired industrial boilers. They are also a general term for coal conveying pipelines. They generally include components such as coal hoppers, downcomers, and diversion troughs. Longer coal chutes often require the addition of airlocks to reduce dust, and diversion flap gates are also needed when diverting coal.

[0004] Most existing detachable coal chutes use welding as their connection method. Coal is an abrasive material, causing severe wear on the side of the chute that is constantly impacted by coal. Over time, this damages the wear-resistant layer, requiring frequent replacement. This necessitates disassembling the entire chute section for replacement. However, welded coal chutes cannot be quickly and efficiently installed and disassembled during maintenance, reducing maintenance efficiency. Furthermore, replacement requires cutting the chutes, which is time-consuming, labor-intensive, and wastes a lot of materials, thus shortening the service life of the coal chutes.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example 1

[0028] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a detachable coal chute, including an upper coal chute body 1 and a lower coal chute body 2. An upper connecting seat 3 and a lower connecting seat 4 are fixedly installed at one end of the upper coal chute body 1 and the lower coal chute body 2, respectively. A lower mounting base 8 is fixedly installed on the inner side of the upper connecting seat 3. A locking box 9 is rotatably installed at one end of the lower mounting base 8 near the swing rod 16. An anchoring spring 10 is installed through the upper end of the locking box 9. A limiting base 11 is fixedly installed at the lower end of the anchoring spring 10. An anchoring head 13 is fixedly installed at the upper end of the anchoring spring 10. A convex fixing block 15 is rotatably installed at the lower end of the limiting base 11. A swing rod 16 is rotatably installed at the end of the convex fixing block 15.

[0029] The outer side wall of the upper connecting seat 3 is provided with several upper mounting grooves 5 at equal intervals, and the outer side wall of the lower connecting seat 4 is provided with several lower mounting grooves 7 at equal intervals. An upper mounting base 6 is fixedly installed at the inner center of the upper mounting groove 5, and a lower mounting base 8 is fixedly installed at the inner center of the lower mounting groove 7.

[0030] Limiting slide rods 12 are fixedly installed at the center of both sides of the limiting base 11. Limiting slide grooves 14 are opened at the center of both sides of the locking box 9 to facilitate the lifting and lowering of the limiting slide rods 12. A movable shaft 17 is rotatably installed through the center of the lower end of the locking box 9. The swing rod 16 is rotatably connected to the locking box 9 through the movable shaft 17. A detachable feed hopper 22 is fixedly installed at the upper end of the coal feeding pipe body 1.

[0031] When the detachable coal chute is in use, the coal to be diverted is first fed into the feed hopper 22, and then passes through the upper coal chute body 1 to the lower coal chute body 2 for diversion. The inner side of the coal chute contains an inner lining plate that can withstand the long-term erosion and wear of the coal flow. In order to improve the wear resistance of the coal chute, it is usually necessary to disassemble and replace the inner lining plate according to the degree of wear to extend the service life of the coal chute. The upper connecting seat 3 and the lower connecting seat 4 are both provided with recessed holes at one end, so that the upper coal chute body 1 and the lower coal chute body 2 can be fixedly inserted and installed inside the recessed holes. Thus, the upper coal chute body 1 and the lower coal chute body 2 can be connected and installed through the upper connecting seat 3 and the lower connecting seat 4 respectively.

[0032] Meanwhile, since the upper mounting groove 5 and the lower mounting groove 7 are equally spaced on the outer walls of the upper connecting seat 3 and the lower connecting seat 4, and an anchoring cylinder 18 is installed at the center of the inner side of the upper mounting groove 5, the operator first rotates the swing rod 16 upward to drive the convex fixing block 15 and the limiting base 11 to rotate with it. Then, the locking box 9 can be driven to swing upward synchronously through the movable shaft 17. Then, the anchoring mounting head 13 is anchored on the anchoring cylinder under the action of the anchoring spring 10. Then, the swing rod 16 is rotated and pressed. Under the action of the limiting base 11 and the limiting slide rod 12, the anchoring spring 10 will not shift its position when locking. The swing rod 16 is rotated and installed on the convex fixing block 15. During the locking and pressing process, the locking box 9 will not shift its position when locking under the action of the movable shaft 17.

[0033] Furthermore, under the action of multiple sets of anchoring springs 10, the upper connecting seat 3 and the lower connecting seat 4 can be tightly anchored and locked together. This allows the upper coal chute 1 and the lower coal chute 2 to be quickly separated by the lifting and pressing swing rod 16 when they need to be disassembled and reassembled. This enables the wear-resistant layer on the inner side of the coal chute to be replaced quickly, avoiding leakage caused by the inability to replace severely worn coal chutes in time, thereby improving the service life of the coal chute.

[0034] Example 2

[0035] Reference Figures 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: an anchoring cylinder 18 is fixedly installed at the center of one end of the lower mounting groove 7, and a square mounting base 19 is fixedly installed at one end of the anchoring cylinder 18. The square mounting base 19 has mounting slots symmetrically opened on both sides. An adjusting shaft 20 is rotatably installed at the center of the inner side of the mounting slot, and an anti-detachment block 21 is rotatably installed on the outer side wall of the adjusting shaft 20.

[0036] When the anchoring head 13 is anchored to the anchoring cylinder 18 under the action of the anchoring spring 10, in order to prevent the anchoring holes on the anchoring head 13 from being properly installed on the anchoring cylinder 18, the anti-detachment block 21 is first rotated so that the two symmetrical anti-detachment blocks 21 on both sides of the square mounting seat 19 can be folded into a parallel state under the action of the adjusting shaft 20, so that the anchoring head 13 can be well anchored. After the anchoring is completed, the two anti-detachment blocks 21 are rotated into a line state, and then installed on the two symmetrical adjusting shafts 20 through the pin, so that the anti-detachment blocks 21 will not rotate during the anchoring process. This avoids the leakage of coal at the connection of the coal drop pipe due to the detachment of the upper connecting seat 3 and the lower connecting seat 4 during operation, which would cause waste of coal and further save production costs.

[0037] The remaining structure is the same as that in Example 1.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this 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 of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
