Description

Technical Field

[0001] This utility model belongs to the technical field of spray gypsum powder processing equipment, specifically relating to an anti-clogging spiral conveyor and discharge machine based on spray gypsum powder processing. Background Technology

[0002] Sprayed gypsum powder is the powder material used in sprayed gypsum slurry preparation. Sprayed gypsum is suitable for plastering and leveling base walls such as concrete walls, brick walls, and aerated concrete walls. It has good thermal insulation, heat insulation, and compressive strength, and is lightweight, which effectively reduces the self-weight of the building and the burden on the foundation load.

[0003] Sprayed gypsum powder has the characteristics of moderate to low fluidity, easy to absorb moisture and clump, easy to generate dust, and certain aerodynamic properties. During the screw conveying process, sprayed gypsum powder is easy to adhere to the wall of the screw conveyor pipe, and the sprayed gypsum powder is prone to blockage in the screw conveyor, reducing the discharge and conveying efficiency of sprayed gypsum powder. To address this, we propose an anti-blockage screw conveyor rod and discharge machine based on the processing of sprayed gypsum powder. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging spiral conveyor and discharge machine based on sprayed gypsum powder processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging spiral conveyor rod based on sprayed gypsum powder processing, comprising:

[0006] The segmented screw conveyor assembly is provided in several parts, and the segmented screw conveyor assemblies are connected in sequence.

[0007] The segmented spiral conveyor assembly includes:

[0008] Transmission rod;

[0009] A spiral conveyor blade, wherein the spiral conveyor blade is spirally wound around the transmission rod;

[0010] The outer edge of the spiral conveyor blade is provided with scraping protrusions that are evenly distributed.

[0011] A push baffle is disposed between the transmission rod and the spiral conveying blade.

[0012] Preferably, one end of the transmission rod is provided with a threaded post, and the other end of the transmission rod is provided with a threaded groove. Adjacent transmission rods are connected by the threaded post and the threaded groove.

[0013] Preferably, bolt holes are provided at both ends of the transmission rod corresponding to the positions of the threaded post and the threaded groove, and locking bolts and locking nuts are provided in the bolt holes.

[0014] Preferably, the spiral conveying blades are mounted on the transmission rod by welding.

[0015] Preferably, the helix angle of the spiral conveyor blade is 9-13°.

[0016] Preferably, the push baffle is arranged in accordance with the axial direction of the transmission rod.

[0017] Preferably, the cross-sectional height of the push baffle is smaller than the cross-sectional outer diameter of the spiral conveying blade.

[0018] Preferably, the spiral conveying blades on adjacent segmented spiral conveying assemblies are spirally connected, and the push baffles on adjacent segmented spiral conveying assemblies are smoothly connected.

[0019] A spray gypsum powder processing discharge machine includes an anti-clogging spiral conveyor based on spray gypsum powder processing.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model has equally spaced scraping protrusions on the outer edge of the spiral conveyor blades. The scraping protrusions scrape the sprayed gypsum powder adhering to the spiral conveyor wall, reducing the adhesion and aggregation of the sprayed gypsum powder and ensuring the normal conveying and use of the sprayed gypsum powder.

[0022] 2. This utility model has a push baffle between the transmission rod and the spiral conveying blade. When the spiral conveying blade conveys the sprayed gypsum powder, the push baffle can effectively push the sprayed gypsum powder to follow the spiral conveying blade forward axially, thereby avoiding the problem of slippage and blockage of the sprayed gypsum powder and improving the smoothness of the conveying of the sprayed gypsum powder.

[0023] 3. The helix angle of the spiral conveying blade in this utility model is 9-13°. By using a spiral conveying blade with a small helix angle, more rotational force is converted into forward axial thrust, which effectively overcomes the frictional resistance and slight agglomeration of the sprayed gypsum powder, ensures stable conveying, prevents slippage and backflow, improves the stable conveying effect of the sprayed gypsum powder, and avoids clogging problems.

[0024] 4. In this utility model, adjacent transmission rods are connected by threaded columns and threaded grooves, and then locked and fixed by locking bolts and locking nuts. Multiple segmented screw conveyor components are connected to realize the free variation of the length of the screw conveyor rod, which is convenient to meet the length requirements of the screw conveyor rod according to actual conveying needs.

Multiple segmented spiral conveying components 1 are connected to realize the free variation of the length of the spiral conveying rod, which is convenient to meet the length requirements of the spiral conveying rod according to the actual conveying needs. The last transmission rod 101 is plugged by threaded plug to prevent sprayed gypsum powder from entering the threaded groove 3.
