Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the intermittent automatic cleaning screen drum sieve of the present invention includes a motor 1, a reducer 2, a drum device, a cleaning device, a frame 11, a sealing cover 12, a feed port 13, a discharge port 14, a Material opening 15 and material outlet 16. The drum device is composed of inner drum screen 3, outer drum screen 4 and transmission gear 5. The cleaning device is made up of hair brush 6, eccentric shaft 7, large sprocket 8, small sprocket 9 and transmission chain 10. The drum device is installed obliquely on the frame 11. The motor 1 is connected with the drum device through the reducer 2 through the shaft coupling 17, and drives the drum device to rotate around the main shaft 18 of the drum screen. When the material enters the inner drum screen 3 from the feed port 13, due to the inclination and rotation of the drum...

Abstract

The invention provides a drum screen capable of automatically and intermittently cleaning screen cloth. The drum screen comprises a motor, a speed reducer, a drum device, a rack, a cleaning device and a brush. The drum device is installed on the rack in an inclined mode. The motor is connected with the drum device through the speed reducer via a coupler. The cleaning device is composed of the brush, an eccentric shaft, a large chain wheel, a small sprocket and a transmission chain; the large chain wheel which is installed on a main shaft of the drum screen is connected with the small sprocket which is fixed to the eccentric shaft through the transmission chain; the brush is fixedly installed on the eccentric shaft. According to the drum screen, the screen cloth of the drum screen can be automatically and intermittently cleaned, so that it is guaranteed that the screen cloth is clear, labor intensity of a worker is mitigated, and screen efficiency is improved; meanwhile, it is also avoided that the brush makes contact with the screen cloth all the time, abrasion between the drum screen and the brush can be effectively reduced, and production cost is lowered.

Description

technical field [0001] The invention relates to an intermittent self-cleaning screen roller sieve, which belongs to the technical field of granular material screening equipment. Background technique [0002] Drum screening machine is a commonly used equipment in the production of compound fertilizers. It is mainly used for the separation of finished products and returned materials, and can also realize the classification of finished products so that the finished products can be evenly classified. However, during the rotation of the trommel screen, due to the centrifugal force and the mutual extrusion force between the materials, a layer of material is often sticky on the screen surface, which seriously affects the screening effect. After a period of use, it must be shut down for manual cleaning. It not only affects the normal operation of the entire technological process and reduces production efficiency, but also causes equipment damage and economic losses in varying degree...
