Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for the production of crystalline resin. Background Technology

[0002] The raw materials for preparing crystalline epoxy resin include epoxy resin, curing agent, accelerator, solvent and filler. After the various raw materials are stirred and mixed, the subsequent crystallization process is carried out. Therefore, a reaction vessel is required during the stirring and mixing process.

[0003] Existing reactors for producing crystalline resins typically rely solely on unidirectional stirring by a stirring rod, resulting in low stirring efficiency. Furthermore, after stirring, some raw materials remain on the inner wall of the reactor, requiring manual cleaning, which is cumbersome. To address these issues, this application proposes a reactor for producing crystalline resins. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reaction vessel for the production of crystalline resins. The reaction vessel improves stirring efficiency through the combination of a stirring plate, a stirring paddle, and a cleaning plate, and can also rinse the residual material on the inner wall of the vessel, replacing manual cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reactor for producing crystalline resin includes a reactor body. A motor is fixedly connected to the top of the reactor body, and a drive gear is fixedly connected to the end of the output shaft of the motor. A hollow column rotatably connected to the reactor body is passed through the reactor body. A driven gear is fixedly connected to the outer wall of the hollow column, and the drive gear meshes with the driven gear. Multiple stirring plates are fixedly connected to the outer wall of the hollow column, and each stirring plate has a through hole. Two connecting rods are fixedly connected to the outer wall of the hollow column, and a cleaning plate is fixedly connected to the end of each connecting rod. A stirring paddle is fixedly connected to the bottom of the hollow column. A cleaning mechanism is provided on the reactor body.

[0007] Preferably, the cleaning mechanism includes a cleaning tank fixedly connected to the side wall of the vessel body, a first connecting pipe fixedly connected to the cleaning tank, a water pump fixedly connected to the side wall of the vessel body, the first connecting pipe fixedly connected to the water pump, the water pump fixedly connected to a second connecting pipe, and a rotary joint installed at the end of the second connecting pipe and the top of the hollow column.

[0008] Preferably, the top of the vessel body is provided with a feed hopper that communicates with it, the top of the feed hopper is rotatably connected to a sealing cover, the top of the sealing cover is fixedly connected to a U-shaped handle, and the outer wall of the U-shaped handle is covered with a protective sleeve.

[0009] Preferably, the bottom of the vessel is provided with a discharge hopper connected thereto, and an electromagnetic valve is fixedly connected to the outer wall of the discharge hopper.

[0010] Preferably, the cleaning plate has a sponge layer on the side wall near the vessel body, and the sponge layer is disposed against the inner wall of the vessel body.

[0011] Preferably, the hollow column has multiple spray holes that are evenly spaced.

[0012] Preferably, the bottom of the vessel body is fixedly connected to four support legs, which are all installed and fixed to the bottom of the vessel body by welding, and the positions of the four support legs are arranged in a rectangular pattern.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. The motor output shaft drives the drive gear, driven gear, hollow column, and multiple stirring plates to rotate. The rotation of multiple stirring plates can stir and mix various raw materials. The rotation of the hollow column can drive the stirring paddle to rotate. Under the action of the blades on the stirring paddle, forced convection and fluid shear force are generated, which makes the liquid disperse and form flow, and the materials in the reactor are stirred and mixed again.

[0015] 2. The rotation of the hollow column drives the two connecting rods and the cleaning plate to rotate, scraping the inner wall of the vessel to prevent material from adhering to the inner wall of the vessel, thus making the material more thoroughly mixed.

[0016] 3. The cleaning solution in the cleaning tank can be injected into the hollow column through the first and second connecting pipes by the water pump. The cleaning solution is sprayed out through multiple spray holes on the hollow column to rinse the inner wall of the vessel. In addition, the rotation of the cleaning plate can thoroughly clean the inside of the vessel, ensuring complete cleaning and avoiding residue, thus replacing manual cleaning.

[0017] In summary, the combination of the stirring plate, stirring paddle, and cleaning plate can improve the stirring efficiency and rinse the residual material on the inner wall of the vessel, replacing manual cleaning. Attached Figure Description
