Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a stirring device for processing unsaturated polyester resin. Background Technology

[0002] Unsaturated polyester resin is a linear polyester formed by the condensation polymerization of saturated diacids and saturated diols. It is further modified by unsaturated diacids to introduce double bonds, giving it the property of being cross-linkable and curable. Due to its unique properties and wide range of applications, unsaturated polyester resin plays an important role in modern industry. During the processing of unsaturated polyester resin, a stirring device is required to achieve uniform mixing of materials, promote chemical reactions, and ensure the stability of product quality.

[0003] Existing mixing devices often leave residues on the inner wall of the mixing drum or the mixing components during the mixing process, which cannot be discharged. This increases the difficulty of subsequent cleaning, and the residues may be mixed into the new materials during the next mixing, resulting in inconsistent product quality between different batches and affecting overall product quality. Utility Model Content

[0004] The technical problem this invention aims to solve is that in existing mixing devices, residual material adheres to the inner wall of the mixing drum or the mixing components and cannot be discharged. Furthermore, the residual material may be mixed into the new material during the next mixing, affecting product quality.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a stirring device for processing unsaturated polyester resin includes a stirring tank and a stirring component installed in the stirring tank. The stirring component is used to fully mix and stir the unsaturated polyester resin. A cover plate is fastened and installed at the upper end of the stirring tank. A water inlet pipe is installed at the upper end of the cover plate. The water inlet pipe is used to assist in the transmission of water flow to clean the inside of the tank.

[0006] The beneficial effects of this utility model are as follows: By using a rotating rod to drive a scraper to remove residual material from the inner wall of the mixing tank, the material adhering to the inner wall during the mixing process can be scraped back into the mixing area, ensuring that the material is always uniformly mixed during the mixing process, thus improving product quality. At the same time, the scraper removes residual material from the inner wall of the mixing tank, allowing the material to be discharged from the mixing tank more thoroughly, reducing material residue. The use of an inclined plate frame for mixing, with a certain angle, allows the raw materials to slide down its surface, preventing the raw materials from sticking and remaining during mixing or cleaning, reducing the difficulty of subsequent cleaning, and improving production efficiency.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the stirring assembly includes a rotating rod, an inclined plate frame installed on the outer wall of the rotating rod, a scraper installed on the outer side of the inclined plate frame, and a drive motor installed on the cover plate. A positioning plate is installed between the scraper and the rotating rod, and a screw is provided at the outer end of the positioning plate. The positioning plate is threadedly fixed to the rotating rod by the screw, and the scraper is fitted against the inner wall of the stirring tank.

[0009] Furthermore, a connecting plate is installed inside the mixing tank. The drive motor is fixedly connected to the rotating rod through the connecting plate. Bolts are provided at both ends of the connecting plate, and the connecting plate is threadedly fixed to the mixing tank by the bolts.

[0010] Furthermore, a conveying pipe is installed inside the cover plate, and multiple sets of water spray holes are opened at the lower end of the cover plate. The water inlet pipe, the conveying pipe and the water spray holes are connected in sequence.

[0011] Furthermore, a feed pipe is installed on one side of the drive motor, and a feeding frame is fixed to one end of the feed pipe.

[0012] Furthermore, a timing module is installed on the upper end of the cover plate, located on one side of the drive motor. A hexagonal nail is fixed to the upper end of the cover plate, and the cover plate is fixedly connected to the mixing tank by the hexagonal nail.

[0013] Furthermore, a discharge pipe is fixedly connected to the lower end of the mixing tank, and an electromagnetic valve is installed at the outer end of the discharge pipe.

[0014] Furthermore, a support column is fixed to the outer end of the mixing tank, and a load-bearing block is fixed to one end of the support column.

[0015] The beneficial effects of adopting the above-mentioned further solution are: by using a conveying pipe to transport water flow out of the spray hole, the water flow can form a strong water flow impact when it is sprayed out of the spray hole, which facilitates the cleaning of some residual materials in the mixing tank. At the same time, the water flow can mix and guide the discharge of residual materials, keeping the tank clean. Attached Figure Description

[0019] like Figures 1-5 As shown, the mixing tank includes a mixing tank 1 and a mixing assembly installed inside the mixing tank 1. The mixing assembly is used to fully mix and stir the unsaturated polyester resin. A cover plate 7 is fastened to the upper end of the mixing tank 1, and a water inlet pipe 11 is installed at the upper end of the cover plate 7. The water inlet pipe 11 is used to assist water flow to clean the inside of the tank. Through the scraper 5 and the inclined plate frame 4, it is ensured that the material is always uniformly mixed during the mixing process, reducing the material residue on the inner wall and improving product quality. The mixing assembly includes a rotating rod 2, an inclined plate frame 4 installed on the outer wall of the rotating rod 2, a scraper 5 installed on the outer side of the inclined plate frame 4, and a drive motor 8 installed on the cover plate 7. A positioning plate 6 is installed between the scraper 5 and the rotating rod 2. The outer end of the positioning plate 6 is provided with screws. The positioning plate 6 is threadedly fixed to the rotating rod 2 by the screws. The scraper 5 is fitted against the inner wall of the mixing tank 1.

[0020] like Figures 2-4As shown, a connecting plate 3 is installed inside the mixing tank 1. The drive motor 8 is fixedly connected to the rotating rod 2 through the connecting plate 3. Bolts are provided at both ends of the connecting plate 3. The connecting plate 3 is threadedly fixed to the mixing tank 1 by the bolts. The connection plate 3 fixed by bolts ensures that the connection between the drive motor 8 and the rotating rod 2 is more secure, improving the operational stability of the device. A conveying pipe is installed inside the cover plate 7. Multiple sets of water spray holes 12 are opened at the lower end of the cover plate 7. The water inlet pipe 11, the conveying pipe and the water spray holes 12 are connected in sequence. Water is conveyed through the conveying pipe, so that it can form a strong impact, effectively cleaning the inner wall of the mixing tank 1 and the mixing components, reducing manual intervention and improving cleaning efficiency. A feed pipe 9 is installed on one side of the drive motor 8. A feeding frame 10 is fixedly connected to one end of the feed pipe 9. The feed pipe 9 and the feeding frame 10 facilitate the addition of raw materials.

[0021] like Figures 3-5 As shown, a timing module 13 is installed on the upper end of the cover plate 7, located on one side of the drive motor 8. A hexagonal nail is fixed to the upper end of the cover plate 7, and the cover plate 7 is fixedly connected to the mixing tank 1 through the hexagonal nail. Combined with the timing module 13 to count the mixing time, it is ensured that the material is always uniformly mixed during the mixing process, avoiding uneven material due to insufficient or excessive mixing. A discharge pipe 14 is fixedly connected to the lower end of the mixing tank 1, and an electromagnetic valve 15 is installed on the outer end of the discharge pipe 14. The discharge is controlled by the electromagnetic valve 15, making the operation more convenient and reducing material residue. A support column 16 is fixedly connected to the outer end of the mixing tank 1, and a load-bearing block is fixed to one end of the support column 16. The support column 16 and the load-bearing block support and fix the mixing tank 1, ensuring its stability and improving the smooth operation of the device.

[0022] Working principle: When unsaturated polyester resin needs to be stirred and processed, the raw material is first added into the mixing tank 1 through the feed pipe 9. Then, the drive motor 8 is started. The drive motor 8 drives the rotating rod 2 to rotate through the connecting plate 3. The inclined plate frame 4 on the rotating rod 2 rotates accordingly. The inclined plate frame 4 has a certain angle, which allows the raw material to slide down its surface during the stirring process, ensuring that the raw material is fully mixed and avoiding sticking residue. At the same time, the scraper 5 installed on the outside of the inclined plate frame 4 is in contact with the inner wall of the mixing tank 1. The scraper 5 scrapes off the residue on the inner wall during the rotation process and scrapes it back into the stirring area. Combined with the timing module 13 to count the stirring time, it is ensured that the material is always uniformly mixed during the stirring process, avoiding uneven material due to insufficient or excessive stirring, and improving product quality.

[0023] When the mixing is complete and the material needs to be discharged, open the solenoid valve 15 on the discharge pipe 14. The material is discharged from the mixing tank 1 through the discharge pipe 14. With the help of the scraper 5, the residual material on the inner wall of the mixing tank 1 can be scraped off more thoroughly, reducing material residue and ensuring that the material can be discharged from the mixing tank 1 more completely.

[0024] When it is necessary to clean the mixing tank 1, water is supplied to the conveying pipe through the water inlet pipe 11. The water flows through the conveying pipe and is sprayed out from multiple water spray holes 12 at the lower end of the cover plate 7, forming a strong water flow impact. The water flow impacts the inner wall of the mixing tank 1 and the mixing components, washing away the residual material. At the same time, the water flow can mix and guide the discharge of the residual material, keeping the mixing tank 1 clean and realizing the mixing treatment of unsaturated polyester resin.
