Description

Technical Field

[0002] High-density phase powder conveying technology is widely used in material conveying in production processes, clean production conveying in food enterprises, and unloading of bulk transport vehicles, but the current technical challenges are:

[0003] 1. Production site: The closed pressure bearing technology of the powder feeding equipment has not been improved during operation. The maximum pressure of the equipment is below 0.012Mpa. Due to the technical parameters of the feeding equipment, the initial kinetic energy of the powder material cannot meet the long-distance transportation of high-density phase powder materials.

[0004] 2. Bulk transportation: Currently, the pressure design of the transport tanks of bulk transport vehicles is less than 0.2 MPa. During the pressurization and unloading process of bulk powder materials, the initial kinetic energy of the powder materials cannot meet the requirements for long-distance transportation of high-density phase powder materials.

[0005] In the existing use of powder conveying devices, most of the powder conveying devices use closed screw conveyor devices, which causes powder to adhere to the components after long-term use, resulting in a decrease in conveying efficiency. Therefore, it is necessary to design a long-distance conveying device for high-density phase powder materials. Summary of the Invention

[0032] See also Figures 1-2 This utility model discloses a remote conveying device for high-density phase powder materials, including a feeding bin 1, a filtering bin 2 and a discharging bin 3;

[0033] The upper end face of the feeding bin 1 is equipped with a feeding hopper 4, the feeding bin 1 is equipped with a stirring assembly, and the discharge end of the feeding bin 1 is connected to the feeding end of the filter bin 2 through a first discharge pipe 5.

[0034] The discharge end of the filter chamber 2 is connected to the inlet end of the discharge chamber 3 via a second discharge pipe 6; a first regulating valve 18 is installed on the first discharge pipe 5, and a second regulating valve 19 is installed on the second discharge pipe 6.

[0035] The discharge end of the discharge bin 3 is equipped with a third discharge pipe 7, which is installed at an angle.

[0036] It also includes a negative pressure component, which is installed outside the filter chamber 2.

[0037] In this invention, the negative pressure assembly includes a negative pressure pump 8 and a negative pressure pipe 9. The negative pressure pump 8 is installed outside the filter chamber 2, and its negative pressure end is connected to one end of the negative pressure pipe 9. The other end of the negative pressure pipe 9 is connected to the filter chamber 2, and an on / off valve 10 is installed on the negative pressure pipe 9. This invention uses a negative pressure pump to draw air from the filter chamber, creating a negative pressure inside. Then, by opening the regulating valve, the negative pressure in the filter chamber rapidly and evenly draws the powder from the feed hopper into the filter chamber for filtration, resulting in high filtration efficiency and thus improved discharge efficiency.

[0038] In this invention, the mixing assembly includes a mixing shaft 11, a mixing rod 12, and a mixing motor 13. The mixing shaft 11 is horizontally installed inside the feeding hopper 1, the mixing rod 12 is installed on the outer wall of the mixing shaft 11, and the mixing motor 13 is installed on the outer wall of the feeding hopper 1, with the motor shaft of the mixing motor 13 being drively connected to the mixing shaft 11. When the mixing motor is turned on, it drives the mixing shaft to rotate, which in turn drives the mixing rod to rotate, thereby uniformly mixing the powder in the feeding hopper.

[0039] In this invention, a screen assembly 14 is installed in the filter chamber 2. The screen assembly 14 includes a frame 15, a coarse steel wire filter screen 16, and a fine steel wire filter screen 17, which are installed inside the frame 15. The coarse steel wire filter screen is used to sieve large particles of powder, and the fine steel wire filter screen is used to sieve small particles of powder. This two-stage sieving method ensures the uniformity of the discharged powder particle size.

[0040] Working principle: The powder to be conveyed is fed into the feeding bin through the feeding hopper. The stirring motor is turned on, which drives the stirring shaft to rotate. The stirring shaft drives the stirring rod to rotate, thereby uniformly stirring the powder in the feeding bin. Then, the first and second regulating valves are closed, and the negative pressure pump is turned on. The negative pressure pump evacuates the filter chamber, creating a negative pressure inside the filter chamber. Then, the first regulating valve is opened, and the negative pressure inside the filter chamber quickly and evenly draws the powder in the feeding bin into the filter chamber and sieves it through the screen assembly. Then, the second and third regulating valves are opened, and the sieved powder is conveyed to the external mechanism.

[0041] In summary, this utility model has a novel structural design, is easy to operate, and can achieve high-efficiency conveying of powder materials, reducing costs and improving work efficiency.
