Description

Technical Field

[0001] The invention relates to the technical field of powder material binder-free granulation, in particular to a powder material binder-free granulation system. Background Art

[0002] Binder-free powder means that the powder is handled or processed without adding any binder. Not adding binders can prevent the introduction of impurities, thereby improving the purity or grade of the product, reducing the steps of adding and mixing binders, simplifying the production process, and reducing the process complexity and operation difficulty. Some binders may have a certain impact on the environment. Not using binders can reduce pollution to the environment and reduce waste gas emissions caused by binder volatilization during the production process.

[0003] After searching, the applicant found that a Chinese patent disclosed a "powder granulator" with a publication (announcement) number of "CN220780202U". The patent is mainly connected to the granulator through a crank-connecting rod mechanism. The granulator motor only needs to rotate in a single direction to realize the up and down reciprocation of the granulator, and the granulator motor does not need to switch between forward and reverse rotations. An ordinary motor can drive the granulator to work continuously and at high temperature, which reduces the requirements for the granulator motor and the cost of the motor. However, the patent cannot pre-treat powders with strong agglomeration and powders with high humidity, resulting in poor uniformity of the feed. For this reason, we propose a powder binder-free granulation system. Summary of the invention

[0004] The object of the present invention is to provide a powder binder-free granulation system to solve the problem in the above background technology that powders with strong agglomeration and high humidity cannot be pretreated, resulting in poor uniformity of feed.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a powder binder-free granulation system, comprising a granulation box and a powder pretreatment mechanism, the powder pretreatment mechanism comprising a pretreatment box, the pretreatment box is connected to a rotating part through a motor, the motor is connected to a strong spring through a fixed frame, the strong spring is connected to an impact rod through a rack column, the pretreatment box is connected to a heating frame through a slide groove, and the heating frame is fixedly connected to a heating cable through a temperature controller.

[0006] As a preferred solution, the pretreatment box is fixedly installed on the upper end of the granulation box, an opening is penetrated in the middle of the upper end of the pretreatment box, a feed port is opened near the left side of the upper end, and an impact groove is fixedly installed in the middle of the bottom inner wall of the pretreatment box.

[0007] As a preferred solution, the slide groove runs through both sides of the pretreatment box, the heating rack is slidably connected to the inside of the slide groove, the heating cable is fixedly installed inside the heating rack, and the thermostat is fixedly installed at both ends of the heating cable.

[0008] As a preferred solution, the motor is fixedly mounted on the upper end of the pretreatment box, and the rotating member is fixedly mounted on the output shaft of the motor.

[0009] As a preferred solution, the fixing bracket is fixedly mounted on the upper end of the motor, the strong spring is fixedly mounted on the lower surface of the end of the fixing bracket away from the motor, the rack column is fixedly mounted on the lower end of the strong spring, and the upper end of the impact rod is fixedly mounted on the lower end of the rack column.

[0010] As a preferred solution, the outer wall of the impact rod is slidably connected to the inner wall of the opening, and the size of its lower end is adapted to the impact groove, and the rack column is meshed with the rotating member.

[0011] As a preferred solution, a material guiding mechanism is arranged above the powder pretreatment mechanism, and the material guiding mechanism comprises a mounting frame, an arc-shaped conduit is inserted into the interior of the mounting frame, and a trumpet dustproof port is fixedly installed at the outer end of the arc-shaped conduit.

[0012] As a preferred solution, a feed adapter is fixedly mounted on the inner end of the arc-shaped conduit, and the feed adapter is plugged into the inside of the feed port.

[0013] The technical effects and advantages of the present invention are as follows: the powder pretreatment mechanism is set up, and the rotating part can be driven to start rotating by starting the motor, so that the rack column meshing with it moves upward, and the strong spring is squeezed. After the rotating part and the rack column are staggered, the rotating part loses its restraint and moves downward under the action of the strong spring, thereby hitting the impact groove at the bottom of the pretreatment box, so that the internal powder vibrates. Under the continuous operation of the motor, the impact rod hits the impact groove back and forth, and the powder vibrates continuously, and the agglomerated powder is dispersed to ensure the uniformity of feeding. At the same time, the powder with high humidity can be dried by the heating cable to improve the quality of the particles. The material guiding mechanism is set up, and the feeding part can be adapted to fit the feeding port just right, so that the powder will not float out of the feeding port. The arc-shaped conduit can be limited by the mounting frame to avoid displacement during feeding. At the same time, a buffer space can be provided for the powder, and it will not fall directly and cause the dust to collide with each other to generate a large amount of dust. The dust in the powder can be adsorbed by the trumpet dustproof port to avoid the dust from spreading outward, creating a comfortable working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The bottom of the pretreatment box 201 is a screen that can filter and screen the powder. Only a part of the outer wall of the rotating part 210 has teeth. When the motor 209 rotates, it will sometimes engage and sometimes disengage with the rack column 211, so that the rack column 211 can move up and down. In conjunction with the strong spring 214, the impact rod 212 can hit the impact groove 204 to achieve the purpose of allowing the screen at the bottom of the pretreatment box 201 to vibrate continuously. When the powder does not need to be dried, the interior of the slide 205 is sealed with a seal, and the surface of the heating rack 206 is transparent explosion-proof and high-temperature resistant glass.

[0025] Specifically, the motor 209 can be started to drive the rotating member 210 to start rotating, thereby causing the rack column 211 meshing therewith to move upward, and the strong spring 214 is squeezed. After the rotating member 210 and the rack column 211 are offset, the rotating member 210 loses its restraint and moves downward under the action of the strong spring 214, thereby hitting the impact groove 204 at the bottom of the pretreatment box 201, causing the powder inside to vibrate. Under the continuous operation of the motor 209, the impact rod 212 hits the impact groove 204 back and forth, and the powder continues to vibrate, dispersing the agglomerated powder to ensure the uniformity of the feed. At the same time, the powder with high humidity can be dried by the heating cable 207 to improve the quality of the particles.

[0026] Embodiment 2:

[0027] Please see attached Figure 1 and attached Figure 6 On the basis of the first embodiment, it is further obtained that a material guiding mechanism 3 is arranged above the powder pretreatment mechanism 2, and the material guiding mechanism 3 includes a mounting frame 301, and an arc-shaped conduit 303 is inserted inside the mounting frame 301, and a trumpet dustproof port 304 is fixedly installed on the outer end of the arc-shaped conduit 303, and an adapter feed piece 302 is fixedly installed on the inner end of the arc-shaped conduit 303, and the adapter feed piece 302 is inserted inside the feed port 202.

[0028] A dust absorption filter is arranged inside the speaker dustproof port 304, which, in combination with its shape, can absorb dust in the powder to prevent the dust from flying.

[0029] Specifically, the feed piece 302 can be adapted to fit the feed port 202 so that the powder will not float out of the feed port 202. The arc-shaped conduit 303 can be limited by the mounting frame 301 to avoid displacement during feeding. At the same time, a buffer space can be provided for the powder so that it will not fall directly and cause collisions between the powders to generate a large amount of dust. The dust in the powder can be adsorbed by the trumpet dustproof port 304 to prevent the dust from spreading outward, thereby creating a comfortable working environment.

[0030] Working principle of the present invention: The present invention is a powder material binder-free granulation system, the adapter feed piece 302 is inserted into the inside of the feed port 202, the powder material is introduced into the inside of the pretreatment box 201 from the arc-shaped guide tube 303, the dust floating in the powder material will be absorbed by the horn dustproof port 304, and the motor 209 is turned on at the same time, so that the rotating part 210 starts to rotate, and then the rack column 211 meshing with it moves upward, and the strong spring 214 is squeezed. After the rotating part 210 and the rack column 211 are offset, the rotating part 210 loses its restraint and moves downward under the action of the strong spring 214. Thereby, the impact groove 204 at the bottom of the pretreatment box 201 is impacted, causing the powder inside to vibrate. Under the continuous operation of the motor 209, the impact rod 212 impacts the impact groove 204 back and forth, and the powder continues to vibrate. After the agglomerated powder is dispersed, it enters the granulation box 1 from the bottom screen of the pretreatment box 201 to start granulation. If the humidity in the powder is high, the heating rack 206 can be inserted into the slide groove 205, and the temperature of the heating cable 207 can be controlled by the thermostat 208 to dry the powder. After drying, the heating rack 206 is pulled out of the slide groove 205 to start the above operation.
