When the material moves to the discharge end of the processing cylinder 2, the fine particle material meeting the particle size requirement is discharged after being separated by the sieve plate 204, and the coarse particle material can be guided to the inlet end of the material for secondary or multiple grinding until the particle size reaches the requirement.
Specifically, the raw materials are delivered to the inside of the connecting pipe 212 through the feeding pipe 302 after being delivered, then enter one side of the mixing cover 211 through the connecting pipe 212, meanwhile, materials (containing a large amount of grinding media) containing large-particle-size particles and flowing back are delivered by the spiral guide plate 210 to enter the other side of the mixing cover 211, and are pushed by the fast rotating push plate 214 to be sprayed into the cylinder 201 through the square groove 213, so that the raw materials and the materials can be well mixed in the spraying process, and subsequent grinding is facilitated.
After the material enters the barrel 201, the power motor 222 drives the ring gear 220 to rotate through the driving gear 221, the ring gear 220 drives the ring plate 216 to rotate through the connecting column 215, and as the ring plate 216 is of an inclined structure, when the ring plate 216 rotates, the ring plate 216 can apply an acting force in an inclined direction to the material and the grinding medium, so that the material and the grinding medium move towards the inner wall of the barrel 201, and the inner wall of the barrel 201 is of a conical structure, so that the material and the grinding medium can move towards the discharge end of the barrel 201 along the inner wall of the barrel 201, the material collides with the flange 219 in the moving process, and collides with the grinding medium and the ring plate 216 again under the guide of the flange 219, so that the material and the grinding medium are pushed again, and in the process, the material collides with the grinding medium for multiple times, so that the grinding effect on the material is improved.
After finishing grinding, the materials and the grinding media move to the discharge end of the cylinder 201, at this time, the materials and the grinding media pass through the through groove 205 and enter the inside of the fixed cover 203, and the fine particle materials conforming to the particle size pass through the sieve plate 204 and enter the discharge cover 202, and then are discharged through the discharge pipe 226; the materials and grinding media which do not reach the grinding standard reach one end of the rotating shaft 209 under the guidance of the inclined sieve plate 204, then enter the material return pipe 208 under the guidance of the spiral guide plate 210 outside the rotating shaft 209, and reach the material inlet along the material return pipe 208, so as to realize continuous mixed grinding of the materials and the grinding media.
In the process of grinding the material, the refrigerant pipe 4 can convey the refrigerant to the refrigerant flow channel 227 to realize cooling of the material and the grinding medium in the cylinder 201, thereby ensuring the grinding effect.
Example two
In the actual grinding process, the raw materials are delivered to the inside of the connecting pipe 212 through the feeding pipe 302 after being delivered, then enter one side of the mixing cover 211 through the connecting pipe 212, meanwhile, materials (containing a large amount of grinding media) containing large-particle-size particles which are returned through the spiral guide plate 210 enter the other side of the mixing cover 211, and are pushed by the fast rotating push plate 214 to be sprayed into the cylinder 201 through the square groove 213, so that the materials and the materials can be well mixed in the spraying process. Often, the concentration of the fed raw material will change due to the change of the production conditions, and the mixing effect of the raw material and the return material (containing a large amount of grinding media) needs to be enhanced to ensure the subsequent grinding effect of the material.
Specifically, as shown in fig. 11, the device further comprises an adjusting portion, the adjusting portion is arranged on one side of the feeding portion 3, the adjusting portion comprises a plugging sleeve 501, the plugging sleeve 501 is arranged on the periphery of the connecting pipe 212, a plurality of electric telescopic members 502 are arranged on the outer wall of the fixing plate 301, and the telescopic portion of each electric telescopic member 502 extends to the inner side of the fixing plate 301 in a sealing manner and is fixedly connected with the plugging sleeve 501.
In normal grinding process, detect the concentration through raw materials concentration detection part and change (especially when raw materials concentration grow), in order to improve the mixed effect of raw materials and backward flow material, control electric telescopic piece 502 is elongated this moment, and drive shutoff sleeve 501 and to compounding cover 211 direction motion, when electric telescopic piece 502 adjusts shutoff sleeve 501 and forms partial seal to compounding cover 211, make a part of square groove 213 shielded, when the material of preliminary mixing in compounding cover 211 is never discharged by blockking square groove 213, because the square groove 213 area that can discharge the material diminishes, the pressure increase when the mixed material of follow square groove 213 is not shielded for square groove 213 at this moment, can increase preliminary mixed material and spray the effect of barrel 201, and then realized adjusting the material mixing effect, do benefit to the follow-up grinding in barrel 201 of material, the problem that the response raw materials concentration that can be very fine changed in actual grinding production.
Example III
The screen 204 is used to separate the materials with the particle size and discharge the materials from the discharge pipe 226, the separation effect of the screen 204 is affected by the blocking degree, and the screen 204 is often blocked after long-term use. At this time, the screen plate 204 needs to be cleaned in time to ensure the separation effect.
Specifically, as shown in fig. 12, the feeding device further comprises an adjusting portion, the adjusting portion is arranged on one side of the feeding portion 3, the adjusting portion comprises a plugging sleeve 501, the plugging sleeve 501 is arranged on the periphery of the connecting pipe 212, a plurality of electric telescopic members 502 are arranged on the outer wall of the fixing plate 301, and the telescopic portion of each electric telescopic member 502 extends to the inner side of the fixing plate 301 in a sealing manner and is fixedly connected with the plugging sleeve 501.
When the screen plate 204 is used for a long time and is blocked, the electric telescopic piece 502 is controlled to stretch and drive the blocking sleeve 501 to move towards the mixing cover 211, when the electric telescopic piece 502 is used for adjusting the blocking sleeve 501 to form a full seal on the mixing cover 211, pressurized flushing water supplied from the feeding pipe 302 reaches the mixing cover 211 through the connecting pipe 212, and because the mixing cover 211 is sealed by the blocking sleeve 501 at this time, the flushing water cannot be discharged from the square groove 213, can only move forwards along the mixing cover 211 and be discharged from the return pipe 208, and flushing fluid discharged from the return pipe 208 can be directly flushed on the screen plate 204 and can clean the screen plate 204. Specifically, be equipped with the flexible sealing layer at shutoff sleeve pipe 501 inner periphery, the setting of flexible sealing layer makes shutoff sleeve pipe 501 can better seal up square groove 213, prevents that the wash water from leaking, and then guarantees the washing effect of sieve 204.
It should be noted that, as shown in fig. 13, when the pressurized flushing water is discharged from the feed-back pipe 208, the control system controls the driving motor to drive the rotating shaft 209 to rotate reversely, so as to drive the spiral guide plate 210 to rotate reversely, and meanwhile, due to the guiding function of the spiral surface of the spiral guide plate 210, the flushing water can be more dispersed in the spraying direction when the pipe orifice of the feed-back pipe 208 is discharged, so that the screen plate 204 can be cleaned in a large area, and the cleaning effect is improved.
