Description

Technical Field

[0001] The utility model relates to the technical field of filter screens, in particular to an adjustable filter screen. Background Technique

[0002] A filter screen is a common industrial and household item used to remove solid impurities from fluids (such as water, air, oil, etc.) to purify the fluid or protect downstream equipment. The filter screen is usually woven into a mesh structure by metal wires or other materials and can intercept particulate matter of different sizes. In industrial applications, the filter screen is widely used in various liquid and gas treatment processes.

[0003] When a common filter screen is in use, it is usually fixed and cannot control or adjust the flow rate of the filtered material during feeding. In some production processes, it is necessary to precisely control the flow rate of the fed material to ensure product quality and production efficiency. If the flow rate cannot be adjusted, it may lead to uneven filtering of the fed material, thereby affecting product quality and bringing certain adverse effects to the usage process. Therefore, we propose an adjustable filter screen. Content of the Utility Model

Through the set flow rate adjustment mechanism, when it is necessary to adjust the flow rate of filtration according to different working conditions or production stages, the internal control motor set inside the motor protection cover can be driven to operate. The motor protection cover plays a role in protecting the internal control motor, and the heat dissipation and dust-proof functions are realized by using the heat dissipation and breathable net. After the internal control motor is started, it drives the internal rotation adjustment plate connected to the rotation control rod to rotate, so that the flow rate adjustment hole and the feeding and discharging port are communicated to expand the flow rate of the filtered material during feeding. The filtering work can be carried out through the filter screen positioning frame and the internal filter screen, and it is discharged from the feeding and discharging port. The rotation of the internal rotation adjustment plate can be adjusted according to different working needs, so as to adjust the range of the feeding and discharging port and the flow rate adjustment hole penetrating the feeding, that is, the flow rate of the filtered material during feeding can be adjusted. When filtration is not required, the internal rotation adjustment plate can also be rotated to cover the lower end of the feeding and discharging port, so that feeding cannot be carried out, effectively solving the problems in the background technique.
