A drum sorting screen

Abstract

The invention discloses a roller type separating sieve. The roller type separating sieve comprises a roller type sieve mesh, a driving wheel, a follower wheel, a cross beam, a bracket, a motor, a supporting plate, a fixed supporting rod and an adjustable heightening mechanism; the roller type sieve mesh is obliquely arranged in the mode that a certain angle is formed between the roller type sievemesh and the horizontal plane; the driving wheel comprises a rotation shaft and a wheel hub arranged on the rotation shaft in a sleeving mode, wherein the wheel hub comprises a plurality of wheel hubsupports; one end of the cross beam is fixedly connected with the wheel hub supports, and the other end of the cross beam is fixedly connected with the follower wheel; the bracket is arranged to be parallel to the rotation shaft of the driving wheel; the motor is arranged on the bracket and fixedly connected with the bracket; the supporting plate is fixedly arranged at a certain included angle relative to the bracket and directly faces the bracket; the fixed supporting rod is fixedly arranged at the end, close to the supporting plate, of the bracket and clamped by the bracket and the supporting plate; and the adjustable heightening mechanism is arranged at the end, far away from the supporting plate, of the bracket, one end of the adjustable heightening mechanism is connected with the bracket, and the other end of the adjustable heightening mechanism is connected with the supporting plate. According to the roller type separating sieve, the condition that the sieve mesh cross beam skewscan be avoided, and the inclination angle of a motor output shaft can be adjusted.

Description

technical field [0001] The invention relates to the technical field of sorting screens, in particular to a drum type sorting screen. Background technique [0002] Sorting screen is a kind of screening equipment that distinguishes solid particles according to particle size. The common sorting sieve is to place the solid particles to be sorted in the screen, vibrate the screen, use the gravity of the solid particles themselves, and control the mesh size of the screen to separate the solid particles according to a certain particle size. In industrial production, vibrating sorting sieves are widely used, such as ore sorting, plastic granule manufacturing, building material sorting and rice noodle selection and other industries. [0003] However, the vibrating sorting screen often has several problems: 1. The vibrating sorting screen vibrates violently during operation, so it often produces a lot of noise; 2. The vibrating sorting screen has simple actions and low sorting effici...

Problems solved by technology

[0003] However, the vibrating sorting screen often has several problems: 1. The vibrating sorting screen vibrates violently during operation, so it often produces a lot of noise; 2. The vibrating sorting screen has simple actions and low sorting efficiency And the screen is very easy to block; 3. After the vibration sorting screen is sorted, it is necessary to specially collect the larger particle size solid particles intercepted by the screen.

[0005] However, the above-mentioned rolling tea sieving machine has gradually exposed some problems in practical application: the crossbeam on the screen is repeatedly subjected to the centrifugal force when the screen rotates for a long time, so the crossbeam gradually deviates, and the crossbeam on the screen The supporting effect of the drum is greatly reduced, which leads to the gradual deformation or sag of the flexible screen; in order to ensure the normal operation of the drum screen, the output shaft of the motor and the rotating shaft of the driving wheel should always be kept parallel. Wear and tear, the parallel state of the output shaft of the motor and the rotating shaft of the driving wheel will gradually deviate.
