Description

Technical Field

[0001] The utility model relates to a spiral extrusion filter used in the chemical industry. Background Art

[0002] The spiral extrusion filter uses a motor to drive the material inside the filter to rotate, and at the same time squeezes the filter device in the cylinder, thereby forming an extrusion filtration of the material in the cylinder to separate the material from the filtrate. Existing spiral extrusion filters cannot adjust the pressure of extrusion filtration, and it is difficult to adapt to different materials, different processes, and different application scenarios. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a spiral extrusion filter.

[0004] A technical solution to achieve the above object is: a spiral extrusion filter, comprising a cylinder, a discharge port assembly arranged at one end of the cylinder, and a motor assembly arranged at the other end of the cylinder;

[0005] The discharge port assembly includes a discharge frame, a discharge end flange and an adjusting device. The adjusting device includes a set of spring clamps and a closing structure arranged at the edge of the discharge port of the cylinder. The spring clamp presses the closing structure at the discharge port. The pressure on the closing structure is adjusted by adjusting the spring clamp, thereby adjusting the degree of compression of the closing structure on the material in the cylinder.

[0006] A cylindrical filtering device layer is arranged on the side wall of the cylinder, a main shaft is arranged in the middle of the cylinder, a spiral propulsion structure is arranged on the main shaft, and the main shaft is directly inserted into a reducer driven by an electric motor and rotates under the drive of the electric motor.

[0010] Furthermore, the feed port is located at the end of the cylinder body close to the motor assembly.

[0011] The utility model provides a spiral extrusion filter, which adopts a spring clamp to press the closed structure at the discharge port. The pressure applied by the spring clamp is adjustable, thereby achieving adjustable pressing force of the closed structure, so that the closed structure can adapt to different application scenarios to apply different pressing forces to the material inside the cylinder, thereby adjusting the filtering effect of the spiral extrusion filter.
