Description

Technical Field

[0001] This utility model relates to the field of powder processing equipment technology, and in particular to a high-efficiency vibrating filter screen. Background Technology

[0002] In the production and processing of materials such as chemical raw materials, building powders, and grain pellets, it is often necessary to open and screen bagged powders to remove impurities and lumps from the materials and ensure the purity of raw materials in subsequent production processes. Currently, most powder processing equipment in the industry requires manual opening of bagged powders. Operators must use a knife to cut open the bag and pour the powder into the screening equipment. This process is not only inefficient but also poses a safety risk of hand injuries to operators. In addition, manual opening can easily cause powder to scatter, generating a large amount of dust, which wastes materials and harms the respiratory health of operators. Even if some equipment is equipped with a simple bag opening structure, its bag opening components are mostly fixed and cannot be flexibly adjusted according to the bag size. Moreover, the connection between the bag opening components and the equipment frame is complicated, making subsequent maintenance and disassembly difficult. Therefore, there is an urgent need for a high-efficiency vibrating filter screen that can automatically open bags and facilitate easy disassembly and maintenance to solve the problems of low efficiency and poor safety in existing technologies. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency vibrating filter screen to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: Design a high-efficiency vibrating filter screen, including an operation box, a screening box, a bag opening component, and a disassembly and assembly component. The operation box is equipped with a dust removal pipe at the upper end and a material feeding rack inside the operation box. The screening box is connected to the lower end of the operation box. A vibration motor is provided at the lower end of the screening box and is elastically connected to the bottom of the operation box. The bag opening component is fixed on the material feeding rack. The bottom of the screening box is equipped with a discharge port and a filter screen inside. The material feeding rack and the filter screen are respectively connected to the operation box and the screening box through the disassembly and assembly component. The bag opening assembly includes a fixing sleeve, a fixing seat, and a cutting blade. The fixing sleeve is sleeved on the rod of the feeding frame, the fixing seat is fixed to the side of the fixing sleeve, and the cutting blade is mounted on the fixing seat. The fixing sleeve and the feeding frame are respectively provided with first screw holes, and a first bolt is threaded into the first screw hole.

[0005] Preferably, the disassembly and assembly assembly includes a first bracket and a second bracket. The first bracket is fixed to the inner wall of the operating box and supported at the lower end of the unloading rack. The second bracket is fixed to the inner wall of the screening box and supported at the lower end of the filter screen. The first bracket has a second screw hole and a second bolt is screwed between the second screw hole and the unloading rack. The second bracket has a third screw hole and a third bolt is screwed between the third screw hole and the filter screen.

[0006] Preferably, the fixing base has a plug groove, the lower end of the cutting blade is integrally formed with a plug block and the plug block is slidably connected in the plug groove, the plug block and the fixing base have corresponding adjustment holes, and the adjustment holes are threaded with adjustment bolts.

[0007] Preferably, at least two sets of shock-absorbing springs are provided between the vibration motor and the bottom of the control box. One end of the shock-absorbing spring is fixedly connected to the housing of the vibration motor, and the other end is welded and fixed to the bottom of the control box.

[0008] Preferably, the upper end face of the first bracket is provided with a positioning hole, and the lower end face of the unloading rack is integrally formed with a positioning pin. The positioning pin can be inserted into the positioning hole to realize the pre-positioning of the unloading rack and the first bracket.

[0009] Preferably, both the first support and the second support are configured as annular structures, with the inner diameter of the first support being smaller than the outer diameter of the feeding rack, and the inner diameter of the second support being smaller than the outer diameter of the filter screen.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a bag-opening assembly within the device. The fixing sleeve is secured to the feeding frame via a first screw hole and a first bolt, completing the installation of the cutting blade. The height of the cutting blade is adjusted by adjusting the position of the insertion block in the insertion slot using an adjusting bolt, allowing the bag to be pushed over the cutting blade. This enables automatic bag opening without requiring the operator to hold the cutting blade or extend the entire device into the operating box. This reduces the safety risks of the operator's hands being cut by the blade or bumped by components inside the operating box. It also avoids the problem of dust inhalation caused by the operator coming into contact with powder, protecting personal health and improving feeding efficiency.

[0011] 2. This utility model features a disassembly and assembly component within the device. The material feeder can be disassembled using the second bolt, allowing complete communication between the control box and the screening box. The filter screen can be disassembled using the third bolt, enabling convenient operation of the filter screen without the need for complete disassembly of the screening box. This reduces the disassembly and assembly steps during equipment maintenance, allowing even a single person to complete the disassembly and assembly of the material feeder and filter screen, improving maintenance efficiency. It also facilitates quick removal, cleaning, or replacement of the filter screen when it becomes clogged or damaged.
