Description

Technical Field

[0001] The utility model relates to the technical field of screw feeders, and particularly relates to a screw housing assembly of a twin-screw feeder. Background Art

[0002] During the conveying process of materials, there is continuous friction between the materials and the screw housing. After long-term operation, the screw housing is prone to wear. In the prior art, the housing of a twin-screw feeder is an integral body; once local wear or damage occurs, the entire housing needs to be replaced. In view of the above technical problems, the utility model provides a screw housing assembly of a twin-screw feeder, which can be used to form a split housing. Once local wear occurs on the housing, only the corresponding part needs to be replaced, and there is no need to replace the entire housing.

[0003] It can be seen that the prior art still needs to be improved and enhanced. Summary of the Utility Model

[0004] In view of the deficiencies of the above prior art, the purpose of the utility model is to provide a screw housing assembly of a twin-screw feeder, aiming to solve the technical problem that in the prior art, the housing of a twin-screw feeder is an integral body and the entire housing needs to be replaced once local wear occurs.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A screw housing assembly of a twin-screw feeder includes a feeding section and a plurality of conveying sections. The feeding section and each conveying section respectively include a straight pipe, and the outer shape of the straight pipe is rectangular; two circular holes are arranged in parallel along the length direction of the straight pipe, and the two circular holes intersect; a feeding port is arranged at the top of the feeding section.

[0007] Further, in the screw housing assembly of the twin-screw feeder, the feeding port is centrally arranged at the top of the feeding section.

[0008] Further, in the screw housing assembly of the twin-screw feeder, the two circular holes in each straight pipe are symmetrically arranged.

[0009] Further, in the screw housing assembly of the twin-screw feeder, the inner cavity formed by the two circular holes is centrally arranged in the corresponding straight pipe.

[0010] Further, in the screw housing assembly of the twin-screw feeder, at least one positioning hole is arranged at the bottom of each straight pipe.

[0011] Further, in the screw housing assembly of the twin-screw feeder, each straight pipe is integrally formed.

[0012] Beneficial effects: The utility model provides a screw housing assembly for a twin-screw feeder. Compared with the prior art, by setting a feeding section and a plurality of conveying sections, a split screw housing can be realized, which has at least the following advantages: (1) When local wear or damage occurs to the screw housing, only the corresponding straight pipe needs to be replaced; (2) By changing the number of conveying sections, screws of different lengths can be adapted, improving the scope of application.

[0019] The utility model provides a screw housing assembly for a twin-screw feeder. To make the purpose, technical solution and effects of the utility model clearer and more definite, the following further details the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0020] Please refer to Figures 1 to 6 , the utility model provides a screw housing assembly for a twin-screw feeder. The drawings are only used to explain the structural principle and are not in proportion to the actual product. The drawings only show the structures related to the invention points of this application, and some conventional structures are not specifically shown. The "a plurality of" described herein refers to an indefinite quantity, because the number of the structures referred to is not the invention point, so no specific limitation is made.

[0021] A screw housing assembly for a twin-screw feeder includes a feeding section A and a plurality of conveying sections B (as Figure 1 shown). The feeding section and each conveying section respectively include a straight pipe 1, and the outer shape of the straight pipe is rectangular; two round holes 102 are arranged in parallel along the length direction of the straight pipe, and the two round holes intersect; a feeding port 101 is arranged at the top of the feeding section.

[0022] Compared with the conveying section, the feeding section has the feature of the feeding port, and the other structures are the same. That is, the positions and sizes of the round holes of each straight pipe are the same.

[0023] Preferably, the feed inlet is centrally arranged at the top of the feed section. Since the feed inlet is centrally arranged, after being connected to the feed hopper, the pressure generated by the feed hopper and the material in the feed hopper on the top of the feed section is evenly distributed, avoiding local deformation or even damage due to uneven stress.

[0024] Preferably, the two round holes in each straight pipe are symmetrically arranged. This arrangement makes the assembly more convenient and does not require distinguishing the front and back directions of the straight pipe.

[0025] Preferably, the inner cavity formed by the two round holes is centrally arranged in the corresponding straight pipe. That is, in the perspective of the side view, the inner cavity formed by the two round holes is centered horizontally and also centered vertically. This arrangement makes the forces on each straight pipe evenly distributed during actual operation.

[0026] As Figure 6 shown, further, at least one positioning hole 103 is provided at the bottom of each straight pipe. Preferably, two positioning holes are arranged along the length direction of the bottom of the straight pipe, so that it is not necessary to distinguish the front and back directions of the straight pipe during installation.

[0027] Preferably, each straight pipe is integrally formed.

[0028] Preferably, each straight pipe is made of ceramics, ensuring that the straight pipe has good strength, wear resistance, corrosion resistance and other properties.

[0029] During actual use, the feed section and each conveying section are sequentially combined together. Different numbers of conveying sections can be adapted to different lengths of screws. After combination, the round holes of each straight pipe are connected end to end for installing two screws. The intersecting part of the round holes corresponds to the meshing part of the two screws.

[0030] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution of the present invention and its inventive concept, and all such changes or substitutions should fall within the protection scope of the present invention.
