It is a pipeline installed between equipment to transport materials from high to low. As a kind of non-standard equipment, the chute occupies a large number in coal preparation plants.

[0003] Most existing chutes are fixed and cannot be moved. When inspecting and repairing the chute or centrifuge, workers need to disassemble the entire device. This requires a lot of disassembly work, takes a long time to inspect, and has high maintenance costs, which is not conducive to long-term use and promotion. To this end, those skilled in the art have provided a feed chute structure for a vertical centrifuge to solve the problems raised in the above background technology. Utility Model Content

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a feeding chute structure of a vertical centrifuge, comprising a chute and a centrifuge arranged at the output end of the chute, the chute and the centrifuge are jointly provided with a wall on the outside, the chute is divided into an upper chute and a lower chute, the outer side wall of the upper chute is fixedly connected to the wall by a sleeved fixed steel plate, the output end of the upper chute is fixedly connected to the lower chute by a first bolt, and the output end of the lower chute is fixedly connected to the centrifuge by a second bolt, and secondly, the lower chute is divided into two groups of reinforced shells, and a transverse movement component for horizontally sliding the two groups of reinforced shells is provided on the outer bottom surface of the fixed steel plate.

[0006] As a further technical solution of the present invention, the transverse movement assembly includes a crossbeam fixedly mounted on the outer bottom surface of the fixed steel plate and located at both ends of the outside of the upper chute, and a slide groove is opened on the corresponding outer side walls of the two groups of crossbeams, and a rotating rod is symmetrically rotatably sleeved on the inner side of the slide groove, and the corresponding ends of the four rotating rods are fixedly mounted with a connecting block, and the four connecting blocks are fixedly connected to the outer side walls of the two groups of reinforced shells in groups of two, and pulleys are rotatably mounted on the outer peripheral surface of the opposite ends of the four rotating rods and located inside the slide groove, and the pulley is slidably connected to the inner side of the slide groove.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-3The present invention provides a technical solution for the feed chute structure of a vertical centrifuge: it includes a chute 1 and a centrifuge 2 arranged at the output end of the chute 1. The chute 1 and the centrifuge 2 are both provided with a wall 101 on the outside. The chute 1 is divided into an upper chute 102 and a lower chute 103. The outer side wall of the upper chute 102 is fixedly connected to the wall 101 through a sleeved fixed steel plate 104. The output end of the upper chute 102 is fixedly connected to the lower chute 103 through a first bolt, and the output end of the lower chute 103 is fixedly connected to the centrifuge 2 through a second bolt. Secondly, the lower chute 103 is divided into two groups of reinforced shells 105. At the same time, a transverse sliding member for horizontally sliding the two groups of reinforced shells 105 is provided on the outer bottom surface of the fixed steel plate 104. Component 3, the transverse movement component 3 includes a crossbeam 301 fixedly mounted on the outer bottom surface of the fixed steel plate 104 and located at both ends of the outside of the upper chute 102, and a slide groove 302 is opened on the corresponding outer side walls of the two groups of crossbeams 301, and a rotating rod 303 is symmetrically rotatably sleeved on the inner side of the slide groove 302, and the corresponding ends of the four rotating rods 303 are fixedly mounted with a connecting block 304, and the four connecting blocks 304 are fixedly connected to the outer side walls of the two groups of reinforced shells 105 in pairs, and a pulley is rotatably mounted on the outer peripheral surface of the opposite end of the four rotating rods 303 and located inside the slide groove 302, and the pulley is slidably connected to the inner side of the slide groove 302, and the outer bottom surface of the two groups of crossbeams 301 is flush with the output port of the lower chute 103. During maintenance, the first bolt and the second bolt are first tightened in sequence to release the fixed connection between the lower chute 103, the upper chute 102 and the centrifuge 2. Then, the lower chute 103 is pushed, and the connecting block 304 drives the pulley on the rotating rod 303 to move horizontally back and forth along the chute 302 on the beam 301, thereby removing the lower chute 103 from between the upper chute 102 and the centrifuge 2, making it easier for operators to inspect, maintain and replace the chute 1 and the centrifuge 2, thereby eliminating the need to disassemble the entire chute 1 structure, reducing workload, saving maintenance time and lowering operating costs.

[0024] A first straight plate 4 and a second straight plate 401 are fixedly mounted on the adjacent outer walls of the two sets of reinforced housings 105, respectively. The first straight plate 4 and the second straight plate 401 are fixedly connected to each other by a third bolt. The third bolt is tightened to separate the first straight plate 4 and the second straight plate 401, thereby facilitating disassembly of the two sets of reinforced housings 105 and facilitating internal maintenance.

[0025] The upper chute 102 has an inverted trapezoidal design, and the two sets of reinforced shells 105 are arranged at an angle. A wear-resistant layer 106 is fixed to the inner sidewalls of the upper chute 102 and the two sets of reinforced shells 105. The inverted trapezoidal and inclined design can, to a certain extent, prevent blockage of the straight cylindrical chute 1 during material feeding and reduce the impact wear caused by materials on the centrifuge 2 during feeding. The application of wear-resistant layer 106 (which can be made of hard-surfaced wear-resistant steel plate, stainless steel plate, cast stone plate, polyurethane plate, or other wear-resistant materials) can prevent long-term wear of the entire feed chute 1 by materials, thereby increasing the service life of the chute 1.

[0026] The working principle of the present invention is as follows: when maintenance is needed, the staff first unscrews the first bolt and the second bolt in sequence and removes them to release the fixed connection between the lower chute 103, the upper chute 102 and the centrifuge 2. Then the staff pushes the lower chute 103, allowing the connecting block 304 to drive the pulley on the rotating rod 303 to move horizontally back and forth along the chute 302 on the beam 301, so that the lower chute 103 is removed from between the upper chute 102 and the centrifuge 2, making it easier for the operator to inspect, maintain and replace the chute 1 and the centrifuge 2.

[0027] At the same time, the third bolt is screwed to separate the first straight plate 4 and the second straight plate 401 , thereby facilitating the disassembly of the two sets of reinforced shells 105 and facilitating maintenance of the interior thereof.

[0028] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
