Embodiment 1

[0031] A kind of drum screen automatic cleaning device for producing compound fertilizer, such as figure 1 , 2 As shown, it includes a transmission device and a rapping device. The connection relationship of the transmission device is: the driving sprocket 12 fixed on the drum screen main shaft 11 is connected with the transmission sprocket 8 installed on the rapping main shaft 1 through a transmission chain 10 .

[0032] The connection relationship of the rapping device is: the rapping main shaft 1 is installed on the drum screen housing 15 through the bearing device 7, and the rapping main shaft 1 is equipped with a cam 5, and the cam 5 corresponds to the fixed ring 13. The rib plate 16 welded to the screen housing 15 fixes the guide cylinder 2 directly above the apex of the fixed ring 13, the rapping ball 4 is connected to the lever 6 through a soft connection 3, and placed in the guide cylinder 2, the lever 6 is welded to the roller screen The guiding fulcrums 9 on the h...

Embodiment 2

[0034] An automatic drum screen cleaning device for compound fertilizer production, the structure can still refer to figure 1 , 2 , but the difference from Example 1 is that the fixed rings 13 are distributed axially on the drum screen with a distance of 1 meter. Of course, the spacing can also be extended to 1.5 meters.

Embodiment 3

[0036] An automatic drum screen cleaning device for compound fertilizer production, the structure can still refer to figure 1 , 2 , but the difference from Embodiment 1 is that the eccentric parts of the cam 5 are evenly distributed in the circumferential direction centered on the rapping main shaft 1 .

Abstract

The invention discloses an automatic cleaning device of a rotary screen for producing compound fertilizer. The device comprises a transmission device and a vibration device; in the transmission device, a driving sprocket fixed on a main shaft of the rotary screen is connected with a driven sprocket arranged on a vibration main shaft through a transmission chain; and in the vibration device, the vibration main shaft is arranged on a shell of the rotary screen through a bearing device, a cam is arranged on the vibration main shaft, the cam corresponds to a fixed ring, a guide cylinder is fixed right above the topmost point of the fixed ring through a rib plate welded with the shell of the rotary screen, a vibration ball is connected with a lever through soft connection and placed in the guide cylinder, and the level is connected with a guide pivot welded on the shell of the rotary screen. The passing rate of cleaning the screen by using the device can reach over 90 percent.

Description

technical field [0001] The invention relates to an automatic cleaning device for a trommel screen used for producing compound fertilizers, in particular to a device which periodically vibrates the screen on the top of the trommel to continuously remove sticky residue on the screen to ensure good screening capacity. Background technique [0002] In the field of compound fertilizer production, the trommel screen is a kind of screening equipment with strong screening ability, but during the rotation process of the trommel screen, due to the centrifugal force and the mutual extrusion force between materials, the trommel screen often falls on the inner screen surface of the trommel screen. A layer of compound fertilizer is pasted on it, and the sieve holes are blocked in a short time, which seriously affects the sieving effect. If it is manually cleaned, the trommel screen cannot be fully enclosed, and large dust will be formed during operation, which is not conducive to manual c...
