Description

Technical Field

[0001] The utility model relates to the technical field of grinding and screening, in particular to a grinding and screening structure for the production of suspensions. Background Art

[0002] Suspension concentrate is a mixture of solid particles suspended in liquid, commonly used in the preparation of liquid medicines or coatings. In the production process of suspension concentrate, it is necessary to grind the solid particles into the required size and sieve the ground powder to remove oversized or undersized particles.

[0003] Most of the existing grinding and screening structures are carried out in separate equipment. Therefore, impurities are ground together with the raw materials and then screened during grinding, which will not only cause certain damage to the grinding structure, but also cause insufficient grinding, resulting in uneven particle size or inconsistent shape. When the ground particles are too large and do not meet the standards, continuing to grind will cause some particles to be over-grinded and the particles to be too small. It will be difficult to screen out the small particles during subsequent screening, which not only reduces the product quality, but also wastes a lot of raw materials. Utility Model Content

A grinding mechanism 4 for grinding suspension production raw materials is provided inside the shell 1.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 2 and Figure 3The grinding mechanism 4 includes a grinding cylinder 41 arranged inside the shell 1, and a discharge pipe 42 fixedly installed on the outer surface of the grinding cylinder 41, a round table 43 is fixedly installed inside the grinding cylinder 41, and a rotating mechanism 5 for grinding the raw materials in the grinding cylinder 41 is movably installed inside the grinding cylinder 41. A recovery mechanism 6 for collecting large particles for re-grinding is provided below the grinding cylinder 41. The grinding disc 55 is ground in the grinding cylinder 41 through the rotating mechanism 5, and the round table 43 makes the raw materials concentrate on the rotation track of the grinding disc 55. After the grinding is completed, the particles enter the recovery mechanism 6 through the discharge pipe 42, and the particles that do not meet the requirements are ground again through the recovery mechanism 6, so as to avoid the problem of extending the grinding time in order to fully grind, resulting in a large number of small particles that are difficult to screen due to over-grinding, while improving the utilization rate of raw materials.

[0026] The rotating mechanism 5 includes a rotating shaft 51 movably mounted at the bottom of the truncated table 43, a connecting rod A52 sleeved on the outer surface of the rotating shaft 51, one end of the connecting rod A52 is fixedly connected to a telescopic rod 53, the outer surface of the telescopic portion of the telescopic rod 53 is sleeved with a connecting rod B54, and a grinding disc 55 movably mounted on one end of the connecting rod B54, the interior of the grinding cylinder 41 is provided with an annular groove, the outer surface of the fixed portion of the telescopic rod 53 is sleeved with a disc 56, one end of the telescopic rod 53 passes through the interior of the grinding cylinder 41, the upper surface of the disc 56 contacts the bottom of the grinding cylinder 41, the telescopic rod 53 rotates inside the annular groove, and a motor 57 is fixedly mounted on the output end of the rotating shaft 51, the grinding disc 55 rotates inside the grinding cylinder 41 by the rotation of the motor 57, the grinding disc 55 can be placed in a suitable position by the extension and contraction of the telescopic rod 53 to control the size of the required particles, and the arrangement of the disc 56 prevents the particles from leaking.

[0027] A pillar 7 passes through the inner wall of the shell 1, and a flat plate 71 is fixedly installed on the upper end of the pillar 7. The upper surface of the flat plate 71 contacts the motor 57. A hole 72 is opened on the upper surface of the flat plate 71. One end of the discharge pipe 42 is opposite to the recovery mechanism 6 through the hole 72. Four groups of pillars 7 are arranged, which pass through the four corners of the bottom of the shell 1 respectively, so as to facilitate the stable operation of the grinding mechanism 4 and the rotating mechanism 5 placed on the upper surface of the flat plate 71. The ground particles enter the recovery mechanism 6 through the discharge pipe 42.

[0028] The recovery mechanism 6 includes a filter screen A61 arranged below the flat plate 71, and an air pump 62 movably installed on the upper surface of the filter screen A61.

Particles on the surface of the filter screen A61 are collected through the collecting port 63 of the air pump 62, and then transmitted to the inside of the grinding cylinder 41 through the air pipe 64 for further grinding, which not only reduces the waste of raw materials, but also avoids the situation where the first grinding time is too long and the particles are too small.

[0029] Specifically, after the grinding disc 55, the telescopic rod 53, the connecting rod A52 and the motor 57 are assembled, the grinding disc 55 is rotated by rotating the motor 57 to rotate inside the grinding cylinder 41. The grinding disc 55 can be placed in a suitable position by extending and retracting the telescopic rod 53 to control the size of the required particles. The setting of the disc 56 prevents the particles from leaking down. The truncated table 43 arranged inside the grinding cylinder 41 makes the raw materials concentrate on the rotation track of the grinding disc 55. The grinding mechanism 4 and the rotating mechanism 5 are placed on the upper surface of the flat plate 71, and the flat plate 71 is stably fixed to the ground by the support 7 to prevent the grinding mechanism 4 and the rotating mechanism 5 from vibrating when the shell 1 vibrates. Since the flat plate 71 is provided with a hole 72, it is convenient for the particles to enter the filter screen A61 through the discharge pipe 42 after the grinding is completed, and the particles on the surface of the filter screen A61 are collected by the collection port 63 of the air pump 62, and then transmitted to the grinding cylinder 41 through the air pipe 64 for re-grinding, so as to avoid the problem of over-grinding to produce a large number of small particles that are difficult to screen due to the extension of the grinding time in order to fully grind, and at the same time improve the utilization rate of the raw materials.

[0030] Embodiment 2:

One end of the discharge trough 65 extends out of the discharge port 3. The movable connection facilitates the replacement and cleaning of the filter A61 and the discharge trough 65. The particles that meet the requirements filtered out by the filter A61 slide out through the discharge trough 65.

[0035] Specifically, the raw material is initially screened through the filter screen B8, and the raw material with impurities removed flows into the grinding cylinder 41 through the pouring hopper 81 for grinding. The movable connection method is convenient for replacing and cleaning the filter screen B8 and the pouring hopper 81. After grinding, it enters the filter screen A61 and the discharge trough 65 through the discharge pipe 42.
