Description

Technical Field

[0001] This utility model relates to the field of resin processing technology, and in particular to a heating and uniform stirring device for producing chlorinated polypropylene resin. Background Technology

[0002] Chlorinated polypropylene resin is a polar thermoplastic resin in which chlorine atoms are introduced into the polypropylene molecular chain. It is a white powder or granules that become colorless after film formation. It is insoluble in ethanol and paraffin hydrocarbons, but soluble in aromatic hydrocarbons, esters, and ketones. It is oil-resistant, heat-resistant, and light-resistant. It can resist corrosion from strong oxidizing acids and strong alkalis. It has good compatibility with most resins and can be used as an adhesive for bonding plastics and metals, as well as a color carrier for coatings.

[0003] In the prior art, Chinese patent application number 202322501174.3 discloses a chlorinated polypropylene resin filtration device, relating to the field of resin processing. It includes a mixing chamber body, with a feeding pipe fixedly connected to the top and a discharge pipe fixedly connected to the bottom. A filtration mechanism is installed at the top of the feeding pipe. This invention uses a feeding pipe to add raw materials into the mixing chamber body, a discharge pipe to discharge the raw materials, and a filtration mechanism to filter the added raw materials. By filtering out impurities, the purity of the raw materials can be improved. A motor provides power for the rotation of a rotating column, which fixes and drives the stirring blades. When the stirring blades rotate, they agitate the resin raw materials inside the mixing chamber body. A scraping mechanism removes resin adhering to the inner wall of the mixing chamber body, thereby reducing raw material residue on the inner wall.

[0004] However, although the above technical solutions can achieve resin feeding filtration, efficient stirring and heating preparation, the filter tube and filter screen are in a static state. When the resin raw material is fed through the filter screen, the flowability is poor, and it may even cause the resin raw material to accumulate and block, thereby affecting the normal feeding of the resin raw material. Therefore, this application proposes a heating and uniform stirring device for producing chlorinated polypropylene resin to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the filter tube and filter screen are in a static state, resulting in poor flowability of the resin raw material when it passes through the filter screen, and even causing the resin raw material to accumulate and block, thus affecting the normal feeding of the resin raw material. Therefore, this invention proposes a heating and uniform stirring device for producing chlorinated polypropylene resin.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heating and uniform stirring device for producing chlorinated polypropylene resin includes a mixing chamber body, the bottom end of which is fixedly connected to a discharge pipe. The mixing chamber body is internally equipped with a stirring mechanism and a heating mechanism. The device also includes:

The ends of the two connecting rods that are close to each other are respectively inserted into the left and right sides of the filter tube. The vibration motors are fixedly installed on the bottom of the corresponding connecting rods.

[0011] A transmission assembly is disposed on the top of the mixing chamber body, and the transmission assembly is respectively engaged with two moving rods.

[0012] As a preferred embodiment of this utility model, the slide block is provided with a sliding hole, and the rear ends of the two moving rods pass through the sliding hole and are slidably connected to the inner wall of the sliding hole.

[0013] In a preferred embodiment of this utility model, a spring is sleeved on the telescopic rod, with the bottom end of the spring fixedly installed on the top of the corresponding movable rod and the top end of the spring fixedly installed on the bottom of the corresponding connecting rod.

[0016] As a preferred embodiment of this utility model, a positioning rod is slidably connected to the knob, and a positioning groove is provided on the top of the mixing chamber body, and the bottom end of the positioning rod can be detached and inserted into the positioning groove.

[0017] Beneficial effects:

[0018] 1. By starting two vibration motors, two connecting rods, filter tubes, and filter screens can be driven to vibrate. At this time, the telescopic rods extend and retract.

The two connecting rods 14 are respectively inserted into the left and right sides of the filter tube 4 at their close ends. The vibration motors 16 are fixedly installed on the bottom of the corresponding connecting rods 14.

[0032] The transmission assembly is located on the top of the mixing chamber body 1, and the transmission assembly is respectively engaged with two moving rods 10.

[0033] With the above structure, by starting the two vibration motors 16, the two connecting rods 14, the filter tube 4 and the filter screen 19 can be driven to vibrate. At this time, the telescopic rod 13 extends and retracts. By vibrating the filter tube 4 and the filter screen 19, the resin raw material can be efficiently screened, impurities can be removed, and the flowability of the resin raw material can be improved by vibration, which can promote feeding and avoid clogging of the filter screen 19.

[0034] As a preferred embodiment of this utility model, the slide block 11 is provided with a sliding hole 12, and the rear ends of the two moving rods 10 pass through the sliding hole 12 and are slidably connected to the inner wall of the sliding hole 12. By providing the sliding hole 12, the moving rods 10 can be stably slidably limited and slidably supported.

[0035] As a preferred embodiment of this utility model, a spring 15 is sleeved on the telescopic rod 13.

[0036] As a preferred embodiment of this utility model, connecting pipes 5 are fixedly installed on both the left and right sides of the filter tube 4. The two connecting rods 14 can be detached and inserted into the two connecting pipes 5 respectively on the side that is close to each other.

[0037] As a preferred embodiment of this utility model, the transmission assembly includes a dual-axis lead screw 6, two support plates 7, a knob 8, and two nuts 9.

[0041] The working principle of this utility model is as follows: In use, first, the mixing chamber body 1 and the vibration motor 16 are powered on by an external power source. Then, by starting the two vibration motors 16, the two connecting rods 14, the filter tube 4, and the filter screen 19 vibrate. At this time, the telescopic rod 13 extends and retracts in coordination. By vibrating the filter tube 4 and the filter screen 19, efficient screening of the resin raw materials can be achieved, removing impurities. Simultaneously, the vibration improves the flowability of the resin raw materials, promotes material feeding, and prevents clogging of the filter screen 19. Furthermore, rotating the knob 8 drives the dual-axis lead screw 6 to... When rotated, the threaded connection between the dual-axis lead screw 6 and the nut 9 causes the two moving rods 10 to move closer or further apart. When the two moving rods 10 move closer together, they can cause the two telescopic rods 13, the two connecting rods 14, and the two vibration motors 16 to move closer together. At this time, the connection between the connecting rod 14 and the connecting pipe 5 on the filter tube 4 enables the stable installation of the filter tube 4. Furthermore, the reverse operation of the above structure allows for the quick disassembly of the filter tube 4. This method facilitates the disassembly and maintenance of the filter tube 4 and the filter screen 19.
