Description

Technical Field

[0001] The utility model relates to the technical field of wet-mixed salt production equipment, in particular to a pneumatic feeding mechanism for wet-mixed salt. Background Art

[0002] At present, the production process of wet-mixed salt of water glass and sodium chloride particles is as follows: after the water glass and sodium chloride particles are stirred and mixed by a salt mixer, workers manually transport the wet-mixed salt to a vibrating screening machine for screening and drying. Throughout the process, the handling of wet-mixed salt depends entirely on manual operation, which seriously increases the labor burden of operators, has low efficiency, and causes waste of manpower. Moreover, some existing feeding mechanisms are not applicable to the feeding of wet-mixed salt. Summary of the Invention

[0003] In order to make up for the defects of the prior art, the utility model provides a labor-saving and efficient pneumatic feeding mechanism for wet-mixed salt.

[0004] The utility model is realized by the following technical solutions:

[0005] A pneumatic feeding mechanism for wet-mixed salt includes a fixed frame. The feature is that a hopper assembly and a stirring assembly are arranged on the fixed frame. The hopper assembly includes a hopper fixed on the fixed frame and a pneumatic feeder. The lower end of the hopper is conical, and the pneumatic feeder is installed at the lower end of the hopper. The stirring assembly includes a motor frame fixedly installed on the fixed frame. A motor is fixedly installed on the motor frame. The output end of the motor faces downward and is connected with a stirring shaft. Stirring blades are arranged on the stirring shaft, and inclined scraping plates that coincide with the conical inner wall of the hopper are arranged at the ends of the stirring blades.

[0006] The stirring shaft is fixedly connected with the motor frame through a stirring frame.

[0007] The stirring frame includes an inclined support frame, and a connecting plate is fixedly arranged at the upper end of the support frame.

[0008] The lower end of the support frame is rotationally connected with the stirring shaft through a copper sleeve bearing.

[0009] The motor is connected with the stirring shaft through a coupling.

[0010] The inclined scraping plate is a parallelogram, and one long side of it contacts the conical inner wall of the hopper.

[0011] There are four stirring blades in total, two on each side, arranged vertically.

[0012] The stirring blades on both sides are arranged staggeredly. The beneficial effects of the utility model are:

[0013] The utility model is provided with a stirring assembly and a pneumatic feeding mechanism. The stirring assembly includes stirring blades and inclined scraping plates. During the feeding process, driven by the stirring blades, the inclined scraping plates scrape the conical inner wall of the hopper, which helps the material to be fed downward through the pneumatic feeding mechanism, preventing the wet mixed salt from sticking to the inner wall of the hopper and preventing the wet mixed salt from sticking in the hopper and not descending, resulting in the interruption of feeding.

[0014] The settings of the motor frame, support frame and copper sleeve bearing make the stirring shaft firmly fixed and enhance the stability during the stirring process. Brief Description of the Drawings

[0015] The following further describes the present utility model with reference to the drawings:

[0016] Figure 1 is a three-dimensional structural schematic diagram of the present utility model;

[0017] Figure 2 is a structural schematic diagram of the stirring assembly.

[0018] In the figure, 1 is a fixed frame, 2 is a pneumatic feeder, 3 is a hopper, 31 is a conical part, 4 is a motor frame, 5 is a motor, 6 is a coupling, 7 is a copper sleeve bearing, 8 is a support frame, 9 is a connecting plate, 10 is a stirring shaft, and 11 is stirring blades. Detailed Description of the Preferred Embodiment

[0019] The attached drawings are specific embodiments of the present utility model. As Figures 1 to 2 shown, this kind of pneumatic feeding mechanism for wet mixed salt includes a fixed frame 1, which is in the shape of a cuboid frame. A hopper assembly and a stirring assembly are installed on the fixed frame 1, where:

[0020] The hopper assembly includes a hopper 3 and a pneumatic feeder 2. The hopper 3 is fixedly installed on the fixed frame 1. The lower end of the hopper 3 is a conical part 31, and the pneumatic feeder 2 is installed at the lower end of the conical part 31.

[0021] The stirring assembly includes: a motor frame 4, which is in the shape of a portal frame and spans across the fixed frame 1. A motor 5 is installed on the motor frame 4. The output end of the motor 5 passes downward through the motor frame 4 and is connected to a coupling 6. The coupling 6 is connected to a stirring shaft 10. A copper sleeve bearing 7 is sleeved on the stirring shaft 10. Two inclined support frames 8 are fixed on the copper sleeve bearing 7. The upper ends of the support frames 8 are installed with a connecting plate 9, and the connecting plate 9 is installed on the lower surface of the motor frame 4, thereby fixing the stirring shaft 10 to make it operate stably.

[0022] The stirring shaft 10 extends downward into the hopper 3 to a position near the bottom of the conical part 31. Four stirring blades 11 are installed on the stirring shaft 10, two on each side, arranged vertically, and the stirring blades 11 on both sides are staggered vertically to ensure that the entire inner wall of the conical part 31 can be scraped without leaving any dead corners. An inclined scraper 12 is installed at the outer end of the stirring blade 11. The inclined scraper 12 is a parallelogram, and its long side fits and contacts the inner wall of the conical part 31, serving to scrape the wet mixed salt adhering to the inner wall of the conical part 31.

[0023] During use, the pneumatic feeder 2 is connected to the vibrating screen through a hose. After the wet mixed salt is added to the hopper 3, the motor 5 is started, and the stirring shaft 10 rotates to stir the wet mixed salt downward and enter the pneumatic feeder 2. After being driven by compressed air in the pneumatic feeder 2, it enters the vibrating screen through the hose; during the stirring process, the inclined scraper 12 scrapes the wet mixed salt adhering to the inner wall of the conical part 31 to prevent it from not descending, thereby causing the feeding to be interrupted.

[0024] Except for the technical features described in the specification, the remaining technical features are all known technologies to those skilled in the art.
