Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a device for automatically screening large blocks of solid particles. Background Art

[0002] The screening device is a device used in the material processing and production process. Its main function is to filter out unqualified materials. For example, in the production and processing of granular materials, due to many reasons such as the large gap between the cutter and the template and the bluntness of the cutter, some large pieces of material will be produced and enter the product silo through the pneumatic conveying system. In the product packaging process, it flows to the entrance of the packaging machine by gravity, causing the pipeline of the packaging machine entrance to be blocked. At the same time, the packaging machine alarms and stops running, seriously affecting the product packaging efficiency. At this time, a deblocker will be used to remove the large pieces of material.

[0003] When the existing deblocker is in use, the deblocker is installed on the vertical pipeline connecting the product silo and the packaging machine inlet. The large blocks of material entrained in the product particles enter from the inlet and are then retained on the upper part of the grille and slide to the edge of the equipment due to gravity. The particles pass through the grille holes normally and enter the packaging machine from the outlet. Then, during the operator's daily inspection, if he finds large blocks of material in the equipment through the window, he can open the quick-opening hand hole to take out the large blocks of material in the equipment and then close the quick-opening hand hole. However, it is found in actual use that when the deblocker is used normally for material screening, more and more granular material powder will adhere to the inside of the window, affecting the clarity of the window, which in turn affects the operator's observation, resulting in excessive accumulation of large blocks of particles, affecting the normal screening of granular materials, and reducing the use effect and work efficiency of the deblocker. Utility Model Content

[0011] Preferably, the output end of the servo motor is provided with a protective sleeve, and the protective sleeve is fixedly connected to the surface of the servo motor.

[0012] The effect achieved by the above components is that, by setting the protective cover, it is difficult for powder to enter the inside of the servo motor when it is in use, thereby ensuring the normal use of the servo motor.

[0019] Preferably, an operating block is fixedly connected to the surface of the bolt, and a plurality of anti-slip protrusions are provided on the surface of the operating block.

[0034] Working principle: When using the deblocker 1 to screen large lumps in granular materials, first install the deblocker 1 on the vertical pipeline connecting the product silo and the packaging machine inlet 2.
