Description

Technical Field

[0001] This utility model relates to the field of powder screening technology, and in particular to a dry screening machine for metal powder production. Background Technology

[0002] With technological advancements and the development of large-scale production, metal powder screening machines have emerged to achieve precise grading of metal powder particles, remove impurities, and improve screening efficiency. Through mechanized and automated screening methods, they have overcome the limitations of traditional methods in terms of capacity and quality control, becoming key equipment in the production process of related fields.

[0003] Traditional metal powder screening machines typically consist of a screen box, screen mesh, vibrating motor, and base. Their working principle is as follows: the vibrating motor generates vibrational power, which is transmitted to the screen box, causing the screen mesh to vibrate reciprocally or circularly. After the metal powder is evenly conveyed to the screen mesh surface, powder particles smaller than the screen mesh aperture fall through the mesh, while larger particles remain on the screen, thus achieving the grading and screening of powders of different sizes. The entire process mainly relies on mechanical vibration to cause relative movement of the powder on the screen mesh, utilizing the difference in screen mesh aperture size to achieve particle separation.

[0004] Existing filter screens often use a fixed structure. During long-term operation, the gaps in the filter screen can become clogged by metal powder, causing the screening efficiency to gradually decrease. Therefore, a dry screening machine for metal powder production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dry screening machine for metal powder production, which aims to improve the problem in the existing technology where the material feeding process lacks an automatic recycling device, causing materials to easily accumulate at the feeding port, requiring manual collection, resulting in low efficiency and easy material waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dry screening machine for metal powder production, comprising a base plate, a plurality of first supports fixedly connected to the top of the base plate, a support ring fixedly connected between the first supports, a screening barrel fixedly connected inside the support ring, a pin box fixedly connected to the surface of the screening barrel, a first baffle slidably connected inside the pin box, a spring fixedly connected to the side of the first baffle away from the screening barrel, a pin slidably connected to the middle of the pin box, a filter screen baffle fixedly connected inside the screening barrel, a first filter screen provided at the top of the filter screen baffle, the pin inserted into the first filter screen, a vibration motor fixedly connected to the bottom of the first filter screen, and a drawstring fixedly connected to the top of the first filter screen;

[0007] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the equipment achieves efficient screening by vibrating the first filter screen through a vibrating motor, thereby improving screening efficiency. The vacuum pump generates suction through the first receiving pipe to draw powder that has not entered the screening barrel into the receiving box. By closing the vacuum pump and valve, the powder in the receiving box enters the receiving barrel for screening. This ensures that the device does not cause environmental pollution due to the flying of powder materials during screening. Furthermore, by recovering the flying powder, it can avoid material waste and harm caused by inhalation.

[0023] 2. In this utility model, by pulling the pin, the first baffle is compressed by the spring, and the pin is disengaged from the first filter screen. The filter screen can be cleaned and replaced by pulling the rope. The spring provides elasticity to the first baffle, and the baffle drives the pin to be firmly inserted into the pin box, thereby fixing the first filter screen in the screening barrel. This allows the filter screen to be easily disassembled and replaced during operation, avoiding filter screen blockage that would reduce screening efficiency. Attached Figure Description
