Description

Technical Field

[0001] This utility model relates to a feeding device, specifically a feeding device for a vibrating screen for plant protein powder. Background Technology

[0002] In the processing and production of plant protein powder, a vibrating screen is required for screening. In existing vibrating screens, the plant protein powder is transported to the top of the screen by an auger, and the material is directly fed into the vibrating screen for screening through an airlock.

[0003] In the existing technology, some small production lines often use manual feeding for vibrating screens. Workers slowly and evenly pour plant protein powder into the feed inlet of the vibrating screen. During this feeding process, because the top of the vibrating screen is open, the flow of plant protein powder during manual feeding will generate dust, which will harm the human respiratory tract and affect the health of workers. Even wearing a mask cannot completely avoid inhaling dust. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for a vibrating screen for plant protein powder, which solves the problems of dust being easily inhaled by workers and harming their health in the existing technology.

[0007] As a further preferred technical solution of this utility model, the protective cover has multiple openings on its side wall, and each opening is provided with transparent glass for closing the opening.

[0008] As a further preferred technical solution of this utility model, the feeding pipe includes a feeding channel located at the center and connected to the powder storage chamber, a ventilation cavity is provided on the side wall of the feeding channel, and a plurality of evenly distributed and downwardly inclined air holes are provided between the feeding channel and the ventilation cavity.

[0009] As a further preferred technical solution of this utility model, each of the ventilation chambers is connected by an air supply pipe, and an air pump is provided at the bottom of the powder storage chamber, and the air pump is connected to the ventilation chamber through an air supply pipe.

[0014] Figure 3 yes Figure 2 Enlarged view of the structure at point A in the diagram. Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] like Figure 1-2As shown, a feeding device for a vibrating screen for plant protein powder includes a powder storage chamber 1. The top of the powder storage chamber 1 is equipped with a feed pipe 11 connected to an external feeding pipe. The powder storage chamber stores the plant protein powder raw material input from the feed pipe. The bottom of the powder storage chamber 1 is equipped with multiple discharge pipes 2 that communicate with and are evenly distributed within the powder storage chamber 1. The discharge pipes convey the plant protein powder in the powder storage chamber downwards to the vibrating screen for sieving. An annular connecting part 12 is provided on the side wall of the powder storage chamber 1. A protective cover 3 extending downwards and covering the periphery of the vibrating screen is provided at the bottom edge of the annular connecting part 12. The powder storage chamber 1 can move up and down. After the powder storage chamber moves down to a certain position, the annular connecting part connects and cooperates with the protective cover to cover the periphery of the vibrating screen, forming a protective enclosure around the opening above the vibrating screen to prevent dust from scattering during feeding and causing workers to inhale it, thus endangering their lives. For the sake of the health of the staff, a fixed plate 14 is provided above the powder storage chamber 1 and is fixedly connected to the external support. The feed pipe 11 extends upward through the fixed plate 14. The fixed plate is fixedly connected to the external support and is suspended and fixed above the powder storage chamber. The feed pipe of the powder storage chamber passes through the fixed plate and is connected to the external conveying equipment. Multiple guide columns 15 are provided on the top surface of the powder storage chamber 1, which pass through the fixed plate 14 and slide with the fixed plate 14. A cylinder 16 is provided at the bottom of the fixed plate 14. The output rod of the cylinder 16 is connected downward to the powder storage chamber 1. The cylinder controls the powder storage chamber to move up and down to separate it from the vibrating screen, which is convenient for inspecting materials and maintaining and cleaning materials. The horizontal positions of the cylinder and each guide column are evenly distributed. When the cylinder is started, it drives the powder storage chamber to move up and down relative to the fixed plate under the guidance and limit of the guide column, so as to approach, cover and separate from the vibrating screen.

[0017] like Figure 2 As shown, the bottom inner side of the protective cover 3 is provided with an annular soft support 31 that can abut against the outer wall of the vibrating screen. The end of the annular soft support 31 is pointed. The annular soft support is made of rubber or silicone material. When the protective cover is lowered to cover the vibrating screen, the annular soft support remains in contact with the outer wall of the vibrating screen, which can avoid wear on the vibrating screen and can be deformed to adapt to the size of the vibrating screen. At the same time, it can achieve complete sealing protection for dust inside the vibrating screen. The side wall of the protective cover 3 is provided with multiple openings 32. The openings 32 are provided with transparent glass 33 for sealing the openings 32. The openings and transparent glass are designed to facilitate the staff to observe the feeding situation at any time when feeding materials to the vibrating screen, and to ensure normal and stable sealing and protection effects.

[0018] like Figure 2-3As shown, the feeding pipe 2 includes a feeding channel 21 located at the center and connected to the powder storage chamber 1. A ventilation chamber 22 is provided around the side wall of the feeding channel 21. Multiple evenly distributed and downwardly inclined air holes 23 are provided between the feeding channel 21 and the ventilation chamber 22. Each ventilation chamber 22 is connected to the other through an air supply pipe 24. An air pump 13 is provided at the bottom of the powder storage chamber 1. The air pump 13 is connected to the ventilation chamber 22 through the air supply pipe 24. The air pump is existing technology and will not be described in detail here. When the air pump is started, gas is sent into each ventilation chamber through the air supply pipe. The gas is then blown out downwardly from the air holes, forming a negative pressure environment. This can accelerate the discharge of plant protein powder from the powder storage chamber into the vibrating screen, avoid the accumulation of plant protein powder and blockage of the feeding channel, effectively improve the feeding efficiency of the vibrating screen, and the evenly distributed feeding channel can achieve uniform feeding of the vibrating screen to avoid local accumulation of plant protein powder.

[0019] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
