Description

Technical Field

[0001] The invention relates to the technical field of sand mills, in particular to a dual-power sand mill. Background Art

[0002] As we all know, a sand mill is an auxiliary sanding machine with specific structural and performance advantages. The abrasive used in the sand mill is zirconium beads. In the actual operation of a traditional sand mill, some zirconium beads in it will be discharged along with the processed materials, causing abnormal consumption of zirconium beads and affecting the purity of the materials. In order to reduce the coordinated material discharge of zirconium beads in the sand mill, we proposed a dual-power sand mill.

[0003] After searching, the Chinese patent application number CN202320462757.7 discloses a dual-power sand mill, which is roughly described as including a frame base, a grinding barrel body, a first bearing seat, a second bearing seat, a first machine spindle, a second machine spindle, a first grinding motor, a second grinding motor and a diaphragm pump. The grinding barrel body is horizontally arranged on the machine base, and the first rotor assembly and the second rotor assembly for grinding the material are respectively arranged inside the two ends of the grinding barrel body. The first bearing seat and the second bearing seat are both arranged on the frame base and are respectively located on the left and right sides of the grinding barrel body. The first machine spindle and the second machine spindle are respectively rotatably mounted on the first bearing seat and the second bearing seat, and one end of the first machine spindle and one end of the second machine spindle extend into the two ends of the grinding barrel body respectively. The first grinding motor and the second grinding motor are respectively arranged on the first bearing seat and the second bearing seat, and the first grinding motor drives the first machine spindle through the first belt, and the second grinding motor drives the second machine spindle through the second belt. The output end of the diaphragm pump is connected with the interior of the grinding barrel body. When it is used, after the equipment is started, first, the material to be ground is injected into the grinding barrel body through the diaphragm pump, and the first grinding motor and the second grinding motor drive the first machine spindle and the second machine spindle to rotate through the first belt and the second belt respectively, so that the first rotor assembly and the second rotor assembly rotate to grind the material in the grinding barrel body.

[0004] Although the above-mentioned existing technical solution can be applied to the sand grinding operation of materials, there is little explanation on the specific structure of the discharge of the sanded materials. During the actual operation of the traditional sand mill, some zirconium beads inside will be discharged along with the processed materials, causing abnormal consumption of zirconium beads and affecting the purity of the materials. The practicality needs to be further enhanced. Summary of the invention

The cooperation of the pipe 13, the vertical drum frame 14, the discharging rotor 15 and the discharging elbow 17 forms a relatively independent external vertical discharging unit, which is connected to the grinding cylinder 2 only through an inclined pipe 12. When working, a small amount of zirconium beads will enter the inside of the discharging cavity in the vertical drum frame 14, and will return to the grinding cavity due to the action of gravity.

[0037] The main motor 10, circulating pump 11 and discharging motor 16 in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art. The preferred model is. In the present invention, we only use it and do not improve its structure and function. Its setting method, installation method and electrical connection method are only required to be debugged and operated according to the requirements of its instruction manual for technicians in this field, and will not be described in detail here.

[0038] In summary, the working process of the dual-power sand mill is as follows: when in use, first place the dual-power sand mill at the desired location, and connect the main motor 10, the circulation pump 11 and the discharge motor 16 to the corresponding control circuits according to the instructions, and at the same time connect the main input pipe 54 and the main output pipe 55 to the air outlet and air inlet of the external cold air circulation supply equipment respectively, and connect the feed flange pipe 51 to the external feed pipe, then start the main motor 10, the circulation pump 11 and the discharge motor 16, and feed the material to be sanded relative to the feed flange pipe 51 through the external feed pipe. The material entering the core tube will be auxiliary cooled in the ventilation chamber and then fed into the grinding cylinder 2 through the feed pipe 7. The operation of the main motor 10 drives the sand mill 3 to rotate in the grinding cylinder 2. The grinding cylinder 2 is pre-loaded with zirconium beads. Along with the rotation of the sand mill 3, the rotating guide frame 18 and the sand mill hammer 22 on the sand mill 3 will rotate synchronously. The material and the zirconium beads will form a relative collision motion with the movement of the rotating guide frame 18 and the sanding hammer 22, so as to accelerate the material sanding operation. When the rotating guide frame 18 rotates, the gradual cut-in guide port 19 thereon can realize the internal and external alternating driving and guiding of the zirconium beads and the material during the rotation process, so as to achieve the purpose of repeated sanding of the material. After the sanding is completed, the material is discharged from the frame base 1 through the sequential guidance of the inclined tube 12, the vertical tube 13, the vertical cylinder frame 14 and the discharging elbow 17. When a small amount of zirconium beads will enter the inside of the discharging cavity in the vertical cylinder frame 14 synchronously with the material, the zirconium beads will return to the grinding cavity due to the action of gravity. A very small number of zirconium beads that have not returned will be thrown to the outer periphery of the vertical cylinder frame 14 under the action of the centrifugal force of the discharging rotor 15, and then flow back to the grinding cylinder 2 under the action of gravity, so as to achieve true no leakage of beads.

[0039] Further, as attached Figure 1 , Attachment Figure 2 and attached Figure 3In the state shown, the lower end of the two-way limit spring 44 is inclined toward the direction approaching the main motor 10. In this limited state, the two two-way limit springs 44 act together on the front synchronous push-pull rod 36 and the rear synchronous push-pull rod 39 to make the two have a tendency to approach the direction of the main motor 10, so that the multiple front wave frames 37 act on the multiple front linkage rods 38 respectively, so as to achieve the front elastic limit hook rod 34 relative to the front step shaft rod 30 to form a relative compression, realize the rotation limit of the front wheel member 25 relative to the front wheel frame 24, and the multiple rear wave frames 40 act on the multiple rear linkage rods 41 respectively, so as to achieve the rear elastic limit hook rod 35 relative to the rear step shaft rod 32 to form a relative compression, realize the rotation limit of the rear wheel member 27 relative to the rear wheel frame 26, so that the grinding cylinder 2 has a relative position stability on the frame base 1. When the sanding mechanism needs to be maintained, the transmission connection between the main motor 10 and the step transmission shaft 4 is first released, and then the rear elastic limit is pulled by the synchronous handle rod 47. The hook rod 35 and the front synchronous push-pull rod 36 form a synchronous movement, so that the two-way limit spring 44 is first compressed to the shortest critical point, and then the bottom end of the rear two-way limit spring 44 tilts in the direction away from the main motor 10. In this state, the multiple front wave frames 37 act on the multiple front linkage rods 38 respectively, so that the front elastic limit hook rod 34 is relatively far away from the front step shaft rod 30, and the rotation limit of the front wheel member 25 relative to the front wheel frame 24 is invalidated. The multiple rear wave frames 40 act on the multiple rear linkage rods 41 respectively, so that the rear elastic limit hook rod 35 is relatively far away from the rear step shaft rod 32, and the rotation limit of the rear wheel member 27 relative to the rear wheel frame 26 is invalidated. In this state, the grinding cylinder 2 can be moved relative to the frame base 1 by rolling the front wheel member 25 and the rear wheel member 27 relative to the front track 28 and the rear track 29 respectively, so as to realize the adaptive adjustment of the space at various locations of the grinding cylinder 2, and facilitate the maintenance and repair of the grinding cylinder 2.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
