[0027] Reference Figure 1 and Figure 2 In one embodiment of the powder conveyor of the present application, the powder conveyor comprises a conveyor belt 1 and a plurality of protective covers 2.

[0028] The conveying belt 1 adopts the structural design of the conveying belt of the existing belt conveyor. The belt conveyor is a commonly used continuous conveying equipment, which is widely used in mining, metallurgy, coal, port, chemical industry, building material and other industries to convey bulk materials or articles. The structure of the belt conveyor is relatively simple, but the various components work together to ensure that the materials can be efficiently and stably conveyed. The conveying belt 1 is the core component of the belt conveyor, which is responsible for carrying and conveying materials, and is usually made of rubber, PVC, nylon, steel wire rope and other materials, and has high strength and wear resistance.

[0029] All the protective covers 2 are arranged along the length direction of the conveying belt 1 and cover the conveying belt 1. In this way, the gypsum powder is not easy to produce dust due to the influence of external air during the conveying process, and the inflow of external air into the protective cover 2 can also be prevented. Each two adjacent protective covers 2 are detachably connected, and a proper number of protective covers 2 can be installed according to the requirements, so as to adapt to conveying belts 1 of different lengths.

[0030] Reference Figure 6 On the basis of the above embodiment, the protective cover 2 can move along the length direction of the conveying belt 1, and the middle part of the protective cover 2 is a flexible expansion part 21. The flexible expansion part 21 is of a corrugated structure and is made of a flexible material such as rubber, so that the flexible expansion part 21 has good flexibility and expansion, and can withstand displacement in different directions. When it is needed to install the protective cover 2 on the curved conveying belt 1, the protective cover 2 can be moved along the conveying belt 1 so that the flexible expansion part 21 corresponds to the bending part of the conveying belt 1. The flexible expansion part 21 is displaced to the shape of the bending part, so as to achieve the purpose of rapid installation. Since the flexible expansion part 21 is provided on each protective cover 2, the protective cover 2 can be compatible with conveying belts 1 of different shapes.

[0031] Reference Figure 3 Specifically, the conveying belt 1 is fixedly connected with guardrails 11 on both sides, and the top of each guardrail 11 is provided with an inner chamfer. The bottom of each protective cover 2 is provided with an outer chamfer, and the two sides of the protective cover 2 are respectively slidably abutted on the two guardrails 11 through the cooperation of the inner chamfer and the outer chamfer. The two guardrails 11 can guide the protective cover 2 to move along the length direction of the conveying belt 1, and can limit the left and right movement of the protective cover 2 to separate from the conveying belt 1.

[0032] Reference Figure 3 and Figure 5 The inner top wall of each protective cover 2 is fixedly installed with an infrared lamp tube 4 at the two ends. The infrared lamp tube 4 is also called infrared radiation lamp or infrared heating lamp, which is a device for heating and drying by using infrared radiation. The infrared lamp tube 4 extends along the length direction of the protective cover 2 and irradiates downward, which can dry the gypsum powder on the conveying belt 1 and further prevent the gypsum powder from caking.

[0033] ReferenceFigure 4 、 Figure 5 and Figure 6 In particular, the protective cover 2 can be arranged in an arc shape, preferably a semicircle. Since the infrared lamp 4 is installed on the inner top wall of the protective cover 2, the load of the protective cover 2 is dispersed on the bottom of both sides of the protective cover 2. In combination with the abutting mode of the inner and outer chamfers on both sides of the protective cover 2, the stability of the protective cover 2 can be improved.

[0034] Referring to Figure 1 and Figure 2 In particular, the detachable connection mode of each adjacent two protective covers 2 can be arranged to be connected through a semicircular flange 3. The adjacent two protective covers 2 are connected by connecting the two flanges and fastened with bolts to form a seal. This connection mode is convenient to disassemble, easy to install and maintain.

[0035] Referring to Figures 1-3 The openings of the protective covers 2 at the head and tail are respectively provided with a baffle 5. The baffle 5 is adapted to the cross-sectional shape of the protective cover 2 and is installed on the opening of the protective cover 2 through bolts. The lower end of the baffle 5 is spaced from the surface of the conveying belt 1 to allow the gypsum powder to pass through. The design of the baffle 5 can improve the sealing property of the protective cover 2 and reduce the influence of external air on the inside of the protective cover 2.

[0036] The use method or working principle of the utility model is as follows:

[0037] First, the infrared lamp 4 is fixedly installed on the inner top wall of both ends of the protective cover 2. Then, the protective covers 2 with a number suitable for the length of the conveying belt 1 are arranged along the length direction of the conveying belt 1 and covered on the conveying belt 1, so that the two sides of the protective cover 2 are respectively slidably abutted on the two guardrails 11 through the cooperation of the inner chamfer and the outer chamfer. Then, the protective cover 2 is moved along the conveying belt 1, the flexible expansion part 21 is correspondingly arranged at the bending part of the conveying belt 1, so that the flexible expansion part 21 is displaced into the shape of the bending part. Finally, the adjacent two protective covers 2 are connected through the two flanges and fastened with bolts, and then the baffle 5 is installed at the opening of the protective cover 2 at the head and tail, so that the conveying process of the gypsum powder is carried out in a closed space.

[0038] The above-described embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as a limitation on the patent application scope. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
