Description

Technical Field

[0001] The utility model belongs to the field of chain bucket conveyor equipment, and particularly relates to a hopper of a chain bucket conveyor for conveying high-temperature materials. Background Art

[0002] The chain bucket conveyor, also known as a trough conveyor, is a device that uses hoppers running along tracks to horizontally or obliquely convey materials. It is widely used in industries such as power plants, mines, and coal mines for conveying various loose materials; such as boiler ash, cement clinker, slag, coke, crushed stones, etc., especially some materials with high temperature, large specific gravity, large particle size, sharp acute angles, and strong abrasiveness. Due to the advantages of flexible layout, large conveying capacity, long service life, small maintenance volume, low operating cost, and large conveying angle, the chain bucket conveyor is deeply welcomed by users.

[0003] Such as Figure 4 , the defects of existing equipment:

[0004] Currently, the chain bucket machine usually has a temperature resistance below 150°C. Since the hopper has a single-layer structure and there is no heat insulation measure for the hopper itself. The high-temperature materials in the hopper will transfer heat along the hopper to the chain and guide rail closer to the hopper.

[0005] When the heat is transferred to the chain, it causes the lubricating oil in the chain idler to flow out, resulting in the loss of lubrication function of the chain idler, increased wear, and rapid failure.

[0006] When the heat is transferred to the guide rail, the expansion of the guide rail is much greater than that of the housing and the frame. However, since the guide rail is welded to the equipment frame, the expansion difference between the guide rail and the housing and the frame cannot be effectively released. Eventually, the equipment is deformed, affecting the operation accuracy of the equipment. And when replacing the guide rail, the sleeper and the guide rail need to be cut off, and then the new guide rail and sleeper are positioned and aligned for welding. The operation is complex and wastes a lot of man-hours. Content of the Utility Model

[0007] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a hopper of a chain bucket conveyor for conveying high-temperature materials, and solve the problems raised in the above background art.

[0008] The utility model is realized through the following technical solutions: A hopper of a chain bucket conveyor for conveying high-temperature materials, comprising: a hopper main body, the hopper main body is composed of a guide rail, a chain idler arranged above the guide rail, and a hopper bin. There are two groups of the guide rail and the chain idler arranged above the guide rail. The two groups of guide rails and the chain idlers arranged above the guide rails are symmetrically arranged. The hopper bin is arranged between the two groups of guide rails and the chain idlers arranged above the guide rails;

[0009] The hopper bin is composed of an outer shell, an inner shell, and refractory insulation cotton arranged inside the inner shell and the outer shell.

[0010] As a preferred embodiment, a plurality of hopper bodies are provided, and the plurality of hopper bodies are evenly arranged on the hopper conveyor.

[0011] As a preferred embodiment, the hopper conveyor includes a head housing, an inclined rising section arranged on one side of the head housing, an arc section for connecting the inclined rising section and the horizontal section, and a tail section arranged at the tail of the arc section. A driving mechanism is arranged on the head housing.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0022] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a bucket of a chain bucket conveyor for conveying high-temperature materials, including: a bucket main body 100, the bucket main body 100 is composed of a guide rail 110, a chain idler 120 arranged above the guide rail 110, and a bucket bin 130. There are two groups of the guide rail 110 and the chain idler 120 arranged above the guide rail 110, and the two groups of guide rails 110 and the chain idlers 120 arranged above the guide rail 110 are symmetrically arranged. The bucket bin 130 is arranged between the two groups of guide rails 110 and the chain idlers 120 arranged above the guide rail 110;

[0023] The bucket bin 130 is composed of an outer shell 133, an inner shell 131, and a refractory insulation cotton 132 arranged inside the inner shell 131 and the outer shell 133.

[0024] As an embodiment of the present invention: there are multiple bucket main bodies 100, and the multiple bucket main bodies 100 are evenly arranged on the bucket conveyor 200.

[0025] The bucket conveyor 200 includes a head housing 210, an inclined rising section 220 arranged on one side of the head housing 210, an arc section 230 for connecting the inclined rising section 220 and the horizontal section, and a tail section 250 arranged at the tail of the arc section 230. A driving mechanism 211 is arranged on the head housing 210.

[0026] Sprockets are arranged between the head housing 210, the inclined rising section 220 arranged on one side of the head housing 210, the arc section 230 for connecting the inclined rising section 220 and the horizontal section, and the tail section 250 arranged at the tail of the arc section 230. The sprockets are driven to move by the driving mechanism 211, and the guide rail 110 is arranged on the sprockets

[0027] The outer shell 133 and the inner shell 131 of the bucket bin 130 are both made of steel plates. There is a sandwich between the outer shell 133 and the inner shell 131, and the refractory insulation cotton 132 is filled between the sandwiches. High-temperature materials are placed inside the inner shell 131.

[0028] The heat of the high-temperature material is first transferred to the inner housing 131, and the inner housing 131 transfers the heat to the outer housing 133 through the refractory insulation cotton 132 filled in the interlayer. The outer housing 133 finally transfers the heat to the chain carrier wheel 120 and the guide rail 110.

[0029] Since the thermal conductivity of the refractory insulation cotton 132 is much smaller than that of steel, very little heat is finally transferred to the chain carrier wheel 120 and the guide rail 110. This greatly reduces the impact of the high-temperature material on the chain carrier wheel 120 and the guide rail 110, enabling the hopper conveyor 200 to convey materials with a temperature higher than 150°C.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
