Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a screening device for powder materials. Background Technology

[0002] In industrial production applications, many materials have strict requirements regarding particle size. Overly large particles can directly or indirectly affect the material's performance. Therefore, powdered materials need to be sieved during manufacturing to ensure the finished product's particle size meets usage requirements. The most common sieving device in production is the filter screen. By placing the material in the filter screen, particles smaller than the screen's mesh size pass through, thus separating out larger, non-compliant powdered materials.

[0003] However, when the material particles are small, the powder material put into the filter screen tends to clump together due to the intermolecular forces, making it difficult for the powder material to pass through the screen. Even if vibration is applied to the filter screen, it is difficult to quickly break up the clump of powder material, resulting in low screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a powder material screening device that can screen powder materials more efficiently.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A powder material screening device includes a screen box and a screen mesh disposed inside the screen box. A scraper and a drive assembly for driving the scraper to reciprocate in the horizontal direction are provided on the upper part of the screen mesh; a vibration motor is provided on the side wall of the screen box.

[0006] Through the above technical solution, by setting a scraper on the upper part of the screen, the reciprocating motion of the scraper, driven by the drive component, evenly spreads the powder material poured on the screen, thereby effectively breaking the agglomeration effect of the powder material. Thus, under the vibration action of the vibrating motor, the powder material can be screened more efficiently and quickly.

[0007] Preferably, the drive assembly includes an electric push rod and a push rod frame, the push rod frame is fixedly connected to the screen box, the electric push rod is horizontally arranged, the rod body of the electric push rod is fixedly connected to the push rod frame, and the piston rod of the electric push rod axially penetrates the side wall of the screen box and is fixedly connected to the scraper.

[0008] With the above technical solution, the electric push rod is installed on the screen box through the push rod frame. The piston rod of the electric push rod moves back and forth, thereby causing the electric scraper to reciprocate in the horizontal direction with high efficiency.

[0009] Preferably, the upper part of the sieve box is provided with a box cover, and the box cover is horizontally hinged to the box body.

[0010] By using the above technical solution, a cover is installed on the top of the sieve box. When screening powder materials, the cover is closed, thereby reducing the dust generated during screening and its pollution to the surrounding environment.

[0011] Preferably, the box cover has a feeding port, and a feeding hopper is provided at the feeding port.

[0012] By using the above technical solution, a feeding port is opened on the box cover, so that powder materials can be fed into the screen box through the feeding hopper when the box cover is closed, making the operation more convenient and faster.

[0013] Preferably, the screen box includes an upper storage section and a lower collection section, wherein the collection section is a trapezoidal shape with a cross-section that gradually decreases from top to bottom; and a discharge port is provided at the lower part of the collection section.

[0014] By using the above technical solution, the lower part of the screen box is set as a stepped platform that gradually decreases in size from top to bottom, making it easier to collect and process the screened materials.

[0015] Preferably, the discharge port is provided with a sealing door for closing the discharge port.

[0016] The above technical solution involves setting up a sealing door to close the discharge port, allowing the collection section at the bottom of the screen box to store the screened powder material. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Example:

[0024] A powder material screening device, hereinafter referred to as the screening device, is described in reference to... Figures 1 to 3 The sieving device includes a sieve box 1 and a screen 2 installed inside the sieve box 1. A cover 3 is installed on the upper part of the sieve box 1, and the cover 3 is horizontally hinged to the box body. A feeding port 31 is opened on the cover 3, and a feeding hopper 32 is installed at the feeding port 31. A vibrating motor 4 is installed on the side wall of the sieve box 1. When using the sieving device to sieve powder materials, the cover 3 is closed, and the powder material to be sieved is continuously fed into the sieve box 1 from the feeding hopper 32, thereby effectively reducing the impact of dust generated during the operation on the surrounding environment. After sieving, the cover 3 is opened, making it convenient for workers to collect and clean the powder material remaining on the screen 2.

[0025] Reference Figures 1 to 3 The upper part of the screen 2 is equipped with a scraper 5 and a drive assembly 6 that drives the scraper 5 to reciprocate horizontally. The drive assembly 6 includes an electric push rod 61 and a push rod frame 62. The push rod frame 62 is fixedly connected to the screen box 1. The electric push rod 61 is horizontally positioned, and its rod body is fixedly connected to the push rod frame 62. The piston rod of the electric push rod 61 is fixedly connected to the scraper 5. The piston rod of the electric push rod 61 extends and retracts, thereby driving the scraper 5 to reciprocate horizontally. When the powder material enters the screen 2 through the feed port 31, the reciprocating motion of the scraper 5 can evenly spread the powder on the screen 2, breaking up the agglomeration of fine powder particles under molecular action. Then, under the vibration action of the vibration motor 4, powder particles with qualified particle size can pass through the screen 2 more efficiently and well.

[0026] Reference Figures 1 to 3 The screen box 1 includes an upper storage section 11 and a lower collecting section 12. The collecting section 12 is a trapezoidal shape with a cross-section that gradually decreases from top to bottom. A discharge port 13 is provided at the lower part of the collecting section 12. A sealing door 14 is provided at the discharge port 13 for closing the discharge port 13. A sealing opening 15 is opened on the side wall of the discharge port 13, and the sealing door 14 is inserted into the sealing opening 15 to close the discharge port 13.

[0027] When using a screening device to screen powder materials, a container is usually installed at the bottom of the screen box 1 to collect the screened powder material. By setting a trapezoidal collection section 12 at the bottom of the screen box 1, which is wider at the top and narrower at the bottom, the screened material can be collected more effectively. Furthermore, by using a sealing door 14 to close the discharge port 13, the screen box 1 can temporarily store the screened material, making the screening device more flexible and convenient to use.
