Description

Technical Field

[0001] The invention relates to the technical field of wet mixing granulators, in particular to a wet mixing granulator and a working method thereof. Background Art

[0002] Granulation is the process of processing materials in the state of powder, melt, aqueous solution, etc. into granules with a certain shape and size. Granulation methods can be divided into three categories: wet granulation, dry granulation, and spray granulation. Among them, wet granulation is the most widely used. Wet granulation is a method of adding a binder to the drug powder and agglomerating the powder together by the bridging or bonding effect of the binder to prepare granules. The granules made by the wet method have a moist surface and have the advantages of good granule quality, beautiful appearance, strong wear resistance, good compression molding, etc., and are most widely used in the pharmaceutical industry; Its working process consists of two steps: mixing and granulation. The powdered material enters the conical hopper from the top of the conical hopper. After the hopper is closed, the powdered material rotates up and down in the container under the stirring of the stirring paddle. At the same time, the material is moved and changed along the direction of the conical wall by the centrifugal force of the stirring paddle, forming a semi-fluid and efficient mixing state. The material is dispersed by collision to achieve full mixing. During granulation, due to the injection of adhesives (syrups, fluid extracts and other fluids), the powder is gradually moistened, the material properties are changed, and the extrusion, friction and kneading of the material by the blades and the barrel wall are strengthened. Under the action of the adhesive, a liquid bridge is gradually generated, and the material is gradually transformed into a loose soft material. Then it is cut into uniform wet particles by the side-mounted high-speed cutting paddle. The Chinese patent proposes a wet mixing granulator, the publication number of which is CN206688648U, comprising: a slurry adding nozzle, a liquid guiding pipe, a rotating shaft, a slurry adding connecting pipe, a silo, a material pot, a stirring shaft, and a stirring paddle; wherein the stirring shaft is arranged below the material pot, and the upper end of the stirring shaft penetrates through the bottom of the material pot and extends into the material pot; the stirring paddle is arranged in the material pot and is detachably sleeved on the stirring shaft; the silo is arranged on the material pot; the slurry adding connecting pipe is connected to the silo; the upper end of the rotating shaft is connected to the silo, and the lower end is connected to the upper end of the stirring shaft; the liquid guiding pipe is connected to the silo through the rotating shaft, and is used to guide the slurry in the silo into the slurry adding nozzle; the slurry adding nozzle is arranged at the discharge port of the liquid guiding pipe.

[0003] Although the above scheme is equipped with a stirring mechanism and a spraying assembly to granulate the powder, the following problems still exist: 1. The vertical drop of the granulation barrel is large, and too much powder is accumulated inside. If you want to achieve the effect of throwing out the powder, you have to increase the stirring speed, which causes the stirring blades inside the mixing barrel to exert a large centrifugal force on the powder. However, negative pressure will be formed in the center of the mixing barrel. The powder that has not had time to be thrown upward by the radial force will accumulate in the center of the mixing barrel. When the powder around the mixing barrel forms particles, the powder in the center will first be wetted and then agglomerated due to the addition of the mixed liquid, which wastes raw materials and has low granulation efficiency, and the granulation quality cannot be guaranteed; 2. The cutting component inside the mixing barrel of the traditional granulator is set separately. When the powder rotation speed inside the mixing barrel is fast, the cutting component rotation speed is too low, which will lead to poor cutting effect, resulting in excessively large particles, irregular particle shape, poor granulation quality, and low management efficiency. In addition, because an additional set of driving mechanisms is required, the production cost of the granulator is increased.

[0004] Therefore, the design is practical and the mounting plate drives the rotating rod to move downward under the action of gravity, and makes the tooth surface of the lower toothed plate mesh with the lower gear, thereby driving the lower toothed plate to rotate, thereby driving the impeller to rotate, and the powder accumulated above the mounting plate is broken up to the barrel wall. At this time, the weight is reduced, and the reset spring pushes the rotating rod to reset, and the impeller stops rotating. This reciprocating process can improve the granulation efficiency and granulation efficiency of the device for the powder, improve the utilization rate of the device for the powder, and solve the problems of powder accumulation and powder agglomeration proposed in the background technology. A wet mixing granulator and its working method are very necessary. Summary of the invention

[0015] Based on the wet mixing granulator described above, the present invention also proposes a wet mixing granulator method; comprising the following steps: Step 1: Add a certain amount of powder into the mixing barrel, add a certain amount of adhesive into the storage barrel, and seal the device; Step 2: Turn on the dual-axis motor to drive the mixing blades to rotate and mix the powders. During the mixing process, add adhesive liquid into the mixing barrel through the suction component and the mixing component; Step 3: During mixing, the dual-axis motor drives the connecting rod and the cutting tool to rotate and cut and granulate the mixture of powder and adhesive liquid; Step 4: After granulation is completed, the dual-axis motor rotates slowly, the piston is opened through the cylinder, and the mixing blades are cooperated to perform the discharge operation.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the mounting sleeve and the mixing blades to rotate through the upper gear and the upper toothed disc, so that the powder is pushed by the mixing blades. The rotation of the mixing blades generates axial force, tangential force and radial force. The axial force throws the powder toward the barrel wall, and the radial force throws the powder toward the barrel wall and makes it rise along the barrel wall. Because the mixing barrel is contracted upward, when the powder rises to a certain height, it will fall to the bottom of the mixing barrel, and part of the powder will continue to be thrown toward the barrel wall by the mixing blades to circulate. Because the mixing barrel is large, the negative pressure generated in the center of the mixing barrel when the mixing blades rotate causes part of the powder to gather in one The powder on the upper side of the mounting plate will fall onto the mounting plate as the granulation progresses, and gradually accumulate. Under the action of gravity, the mounting plate drives the rotating rod to move downward, and the tooth surface of the lower toothed plate meshes with the lower gear, thereby driving the lower toothed plate to rotate, thereby driving the impeller to rotate, and the powder accumulated on the upper side of the mounting plate will be broken up onto the barrel wall. At this time, the weight is reduced, and the return spring pushes the rotating rod to return to its original position, and the impeller stops rotating. This reciprocating process can improve the granulation efficiency and granulation efficiency of the device for the powder, improve the utilization rate of the device for the powder, and solve the problems of powder accumulation and powder agglomeration mentioned in the background technology.

[0017] 2. In the present invention, during the powder mixing, the air suction component and the second transmission pipe extract part of the air inside the mixing barrel, so that a negative pressure state is formed inside the mixing barrel. At this time, the adhesive liquid inside the mixing component is sucked into the mixing barrel through the first transmission pipe. At the same time, the adhesive is dispersed through the diverter during the suction, so that the adhesive and the powder are fully and evenly mixed, thereby improving the mixing degree of the powder and the adhesive inside the device, improving the mixing efficiency, and then improving the granulation quality and efficiency.

[0018] 3. The present invention uses a dual-axis motor to drive a cutting tool to cut the viscous powder mixture, so that the powder and the adhesive form particles. When the powder inside the mixing barrel forms uniform particles, the cylinder is opened, and the cylinder pushes the connecting plate to move, thereby driving the piston to withdraw the discharge barrel. At this time, the particles are discharged through the through holes opened at the bottom of the discharge barrel, completing the granulation and discharge operation, thereby improving the discharge efficiency and automation level of the device, and further improving the granulation work efficiency of the device.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

A through hole is fixedly opened on the bottom end surface of the mixing barrel 8, and a mounting sleeve 901 is rotatably installed on the inner wall of the through hole through a bearing sleeve. The inner wall of the mounting sleeve 901 is slidably connected to the side of the rotating rod 906, a mixing blade 902 is fixedly installed on the side of the mounting sleeve 901, and an upper toothed disc 903 is fixedly installed on the side of the mounting sleeve 901; Specifically, when using, first, open the locking assembly 24, hold the handle 22, and open the upper cover 20 with the hinge 19 as the center of the circle, and then pour the granulated powder into the mixing barrel 8; add the adhesive liquid into the storage barrel 14 through the feeding port 15, and mix it thoroughly through the mixing assembly 13, and then close the upper cover 20 and the mixing barrel 8 through the sealing ring 21 and the locking assembly 24 through the handle 22; then turn on the dual-axis motor 602, the dual-axis motor 602 drives the upper gear 702 to rotate, and then drives the upper gear plate 903 to rotate , further drives the installation sleeve 901 and the mixing blade 902 to rotate, and then drives the powder to rotate.
