Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a negative pressure unloader. Background Technology

[0002] In industrial production, material unloading is a crucial step in the production process. Traditional unloading devices often suffer from low unloading efficiency and insufficient control precision, impacting production efficiency and product quality. Furthermore, dust generation is a common problem in current powder material batching processes, creating a poor working environment that is unsafe and can even endanger the health of workers, thus seriously affecting the production, survival, and development of enterprises.

[0003] To overcome dust generation during powder material batching, this utility model provides a negative pressure unloader specially designed and manufactured to address the aforementioned problem. This device can prevent dust generation during material batching due to various material characteristics, thereby ensuring continuous, safe, and stable production operation. Utility Model Content

[0004] This utility model provides a negative pressure unloader to solve the technical problem of poor environment caused by dust in the material batching process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This application provides a negative pressure unloader, including an unloader body, an unloader inlet at the top of the unloader body, an unloader outlet at the bottom of the unloader body, a central pipe connected to the lower end of the unloader outlet, and a negative pressure pipe on the upper side of the unloader body, which generates negative pressure around the central pipe to help the material flow smoothly out of the unloader body and prevent dust from being generated at the unloader inlet at the top of the unloader.

[0007] Furthermore, a first control valve is provided at the outlet of the unloader to facilitate precise control of the speed and quantity of material discharged from the unloader body.

[0008] Furthermore, a second control valve is provided on the negative pressure pipe to precisely control the gas flow rate and the magnitude of the negative pressure.

[0009] Furthermore, the diameter of the unloader body is Ф900mm~Ф1500mm, the diameter of the negative pressure pipe is Ф100mm~Ф250mm, and the diameter of the central pipe is Ф300mm~Ф600mm.

[0010] The beneficial effects achieved by this utility model are:

[0011] The negative pressure unloader provided by this utility model partially encloses the unloader body to form a relatively closed chamber. A negative pressure pipe is added to the unloader body to create a certain negative pressure in the batching device. A central pipe is added to the unloader body to provide a buffer for dust during the material falling process, thus separating the material from the dust. Through negative pressure technology and material buffering design, the dust problem in the powder material batching process is effectively solved, the working environment is improved, production safety is enhanced, unmanned operation is achieved, and production costs are reduced.

Material is discharged from the bottom outlet 3 into other production equipment and systems. A negative pressure pipe 5 is provided on the upper side of the unloader body 1, and its negative pressure surrounds the central pipe 4, thereby preventing material from overflowing from the unloader inlet 2 at the top of the unloader body 1 and generating dust.
