Problems solved by technology

[0003] However, in the actual production process, it is often found that impurities such as insoluble matter appear in the products crushed by the crushing and finishing machine, resulting in unqualified products. After inspection, most of the insoluble matter is sealing materials. Friction, which will cause the material of the seal to wear out. In view of this, in order to improve the quality of the product and expand the pass rate; and the current granulation mechanism may cause excessive temperature to the granules due to high-speed operation, which in turn affects the physical and chemical properties of the granules. Unable to meet the high-standard medicament quality requirements, in view of the above problems, the present invention is designed

Embodiment 1

[0028] Such as figure 1 , figure 2 As shown, a mechanism suitable for granulation at room temperature includes a frame 1, a feed hopper 2, a transmission seat 4, a machine chamber 6, a rotary knife 10, an inner screen 11, an outer screen 11, a discharge cylinder 13, transmission control system;

[0029] The feed hopper 2 is arranged above the frame 1, and the machine chamber 6 is arranged below the feed hopper 2, and the machine chamber 6 is fixed on the frame 1, and the bottom of the machine chamber 6 is connected with the discharge cylinder 13, and the center of the machine chamber 6 is provided with The transmission seat 4 located on the frame 1, the rotating seat includes a transmission main shaft connected to the rotary knife 10, a bearing box 7 sleeved on the periphery of the transmission main shaft, and a sealed connection between the bearing box 7 and the transmission main shaft is also arranged in the bearing box 7 The sealing ring 8 of the gap, the receiving tray ...

Embodiment 2

[0034] The cold source device system includes a compressor refrigeration device and a cold storage device, the cold storage device is filled with a cold storage liquid capable of refrigeration, and the compressor refrigeration device includes an evaporator, and the evaporator is immersed in the cold storage liquid.

[0035] The setting of the receiving tray 9 can intercept the impurities when the friction between the high-speed rotating main shaft driven by the transmission control system and the sealing ring 8 causes the abrasion of the sealing material to generate impurities, thereby preventing the impurities from falling into the screen 11 Inside, into the product, thus ensuring the quality of the product and improving the pass rate of the product. In addition, the material receiving tray 9 must be able to prevent the secondary leakage of the intercepted impurities, that is, the seamless connection between the blocking arm and the material receiving body or the internal seal...

Abstract

The invention discloses a mechanism suitable for normal temperature particle granulation. The granulation mechanism comprises a frame, a feeding hopper, a transmission seat, a machine chamber, a rotary cutter, an inner screen mesh, outer screen mesh, a discharging barrel and a transmission control system; the feeding hopper is arranged above the frame, the machine chamber is arranged below the feeding hopper, the machine chamber is fixed on the frame, the lower portion of the machine chamber is connected with the discharging cylinder, the center of the machine chamber is provided with the transmission seat on the frame, and the transmission seat comprises a transmission main shaft connected with the rotary cutter, a bearing box sleeved in the periphery of the transmission main shaft, and a sealing ring for sealing a connection gap between the bearing box and the transmission main shaft. The granulation mechanism can effectively control the temperature of particles to make the change of the temperature of the granulated particles small and have no influences on the physical and chemical properties of the particles in order to meet the quality requirements of the particles.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a mechanism suitable for normal-temperature granulation sizing. Background technique [0002] The crushing and granulating machine has fast granulation and good effect. When the material enters the inner chamber of the machine, under the action of the high-speed operation of the crushing knife, the material forms a vortex fluid, which makes the material generate a strong centrifugal force and spreads the material to the screen bucket hole surface. At the same time, high-speed gap shearing, extrusion and material self-grinding are generated between the crushing knife and the screen bucket, making the material smaller and smaller. At the same time, under the action of centrifugal force, the same particles as the holes are discharged from the mesh. Therefore, the crushing and granulating machine is widely used in the pharmaceutical, chemical, and food industries. [0003] However, in the ...
