Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a current limiting device for a tubular belt conveyor. Background Art

[0002] The tubular belt conveyor is a belt conveyor in which the carrying and return branch conveyor belts are curled into a tubular shape. It is a new type of conveyor that combines pipeline conveying and belt conveying. It has the advantages of a large conveying inclination angle, a small curvature radius, a small cross-sectional area of ​​the fuselage, three-dimensional curved conveying, and the conveyor belt does not deviate. It also facilitates the layout, maintenance, management, and environmental protection of the conveying line.

[0003] However, the material conveying capacity is limited by the width of the conveyor belt. In the dry sorting and transportation of iron ore, due to the different distribution positions of iron ore in the mining area, the grade of iron ore varies. The coarse concentrate selected by the dry magnetic separator is more or less. When the iron ore grade is high, the dry magnetic separator selects more coarse concentrate, and the tubular belt conveyor cannot pass through, which will cause tube expansion. In severe cases, it will cause the risk of belt tearing, belt frame deformation, and damage to the motor and reducer. The existing solution mainly relies on manual processing when the tube expansion phenomenon occurs, which has the problems of long maintenance time, high labor intensity of personnel, and low material transportation efficiency. Therefore, it does not meet the existing needs, and a current limiting device for a tubular belt conveyor is proposed. Summary of the Invention

[0004] The purpose of the utility model is to provide a flow limiting device for a tubular belt conveyor. After the dry magnetic separator selects the material, the material first passes through the guide plate and then enters the interior of the tubular belt conveyor. By arranging a flow limiting plate on the side of the guide plate, the flow limiting plate limits the inlet and outlet of the material after the material passes through the guide plate, so that excess material is intercepted, thereby ensuring that the material entering the tubular belt conveyor will not expand, thereby improving the material transportation efficiency and solving the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tubular belt conveyor flow limiting device, comprising a material guide plate and a flow limiting plate, wherein the flow limiting plate is located on one side of the material guide plate, a bottom plate is arranged between the flow limiting plate and the material guide plate, an adjusting bolt is arranged above the flow limiting plate, a conveyor belt is arranged below the flow limiting plate, a semicircular material guide trough is arranged inside the material guide trough, the conveyor belt is located inside the material guide trough, and the conveyor belt is an arc-shaped structure, a positioning pin is provided on one side of the bottom plate, the bottom plate is connected to the material guide plate, and a roller is provided at the lower end of the bottom plate, and at least two rollers are provided, and the side surfaces of the two rollers are respectively in contact with the two ends of the conveyor belt.

[0006] Preferably, a limiting long slot is provided inside the current limiting plate, one end of the positioning pin is threadedly connected to the base plate, the other end of the positioning pin passes through the limiting long slot, and the part of the positioning pin passing through the limiting long slot is connected to the nut.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model provides a flow limiting plate on the side of the guide plate, and a flow limiting groove at the lower end of the flow limiting plate. After the dry magnetic separator selects the material, the conveyor belt transports the material through the guide plate and then enters the interior of the tubular belt conveyor. When the material passes through the guide plate, the flow limiting groove and the conveyor belt form a transportation channel. The transportation channel limits the entry amount of the material, so that the excess material is intercepted by the flow limiting plate, thereby ensuring that the material entering the tubular belt conveyor will not expand, thereby improving the material transportation efficiency.

[0013] The utility model provides a positioning plate at the upper end of the flow limiting plate, one end of the positioning plate is connected to the bottom plate through a supporting plate, and a fixing plate is provided on the side of the bottom plate. The upper end of the adjusting bolt extends upward and passes through the positioning plate and the fixing plate in sequence. The part of the adjusting bolt passing through the fixing plate is connected to the nut. When a person rotates the nut, the part of the adjusting bolt passing through the fixing plate is lengthened or shortened, thereby causing the flow limiting plate to move up or down, and then the flow limiting plate can be used to limit the amount of material entering. At the same time, the two rollers respectively support the two ends of the conveyor belt, thereby avoiding mutual friction between the conveyor belt and the flow limiting plate, and improving the service life of the conveyor belt.

[0020] In order to solve the problem of long maintenance time and high workload of personnel when the tubular belt conveyor has tube expansion, which leads to low material transportation efficiency, please refer to Figure 1-4 The utility model provides an embodiment: a tubular belt conveyor flow limiting device, including a guide plate 5, and a flow limiting plate 2, the flow limiting plate 2 is located on one side of the guide plate 5, a bottom plate 1 is provided between the flow limiting plate 2 and the guide plate 5, an adjusting bolt 204 is provided above the flow limiting plate 2, a conveyor belt 4 is provided below the flow limiting plate 2, a semicircular guide trough is provided inside the guide plate 5, the conveyor belt 4 is located inside the guide trough, the conveyor belt 4 is an arc-shaped structure, a positioning pin 103 is provided on one side of the bottom plate 1, the bottom plate 1 is connected to the guide plate 5, and a roller 3 is provided at the lower end of the bottom plate 1, and at least two rollers 3 are provided. The side surfaces of the two rollers 3 are in contact with the two ends of the conveyor belt 4 respectively.

The part of the positioning pin 103 passing through the limiting long groove 201 is connected to the nut, and pressure plates 301 are set at both ends of the roller 3. The roller 3 is axially connected to the pressure plate 301, and a bracket 302 is set on one side of the pressure plate 301. The two ends of the bracket 302 are respectively connected to the two pressure plates 301, and the side of the bracket 302 is connected to the base plate 1.

[0022] After the dry magnetic separator has dry-selected the material, the conveyor belt 4 transports the material through the guide plate 5 and then into the interior of the tubular belt conveyor. When the material passes through the guide plate 5, the flow limiting groove 202 and the conveyor belt 4 form a transportation channel. The transportation channel limits the amount of material entering, so that the excess material is intercepted by the flow limiting plate 2, thereby ensuring that the material entering the tubular belt conveyor will not expand, thereby improving the material transportation efficiency, shortening the maintenance time, and further reducing the subsequent labor intensity of the personnel.

[0023] A fixing plate 101 is provided on the side of the base plate 1, and a through hole 104 is provided inside the fixing plate 101.

A spring 205 is provided between the fixing plate 101 and the positioning plate 203, and the spring 205 is sleeved on the adjusting bolt 204.

[0024] The personnel rotates the nut on the upper end of the adjusting bolt 204 to lengthen or shorten the portion of the adjusting bolt 204 passing through the through hole 104, thereby causing the limiting plate 2 to move up or down, and then the flow limiting plate 2 can be used to limit the amount of material entering, thereby improving the flexibility during use. At the same time, the two rollers 3 respectively support the two ends of the conveyor belt 4, so that the two ends of the conveyor belt 4 are expanded outward, avoiding mutual friction between the conveyor belt 4 and the limiting plate 2, and further improving the service life of the conveyor belt 4.

[0025] Working principle: After the dry magnetic separator selects the material, the conveyor belt 4 transports the material through the guide plate 5 and then enters the interior of the tubular belt conveyor. When the material passes through the guide plate 5, the excess material is intercepted by the flow limiting plate 2, thereby ensuring that the material entering the tubular belt conveyor will not expand, thereby improving the material transportation efficiency.
