Description

Technical Field

[0001] This utility model relates to the field of reaction vessel equipment technology, and in particular to a temperature-controlled reaction vessel for the production of photoresist phenolic resin. Background Technology

[0002] As a key component of photoresists, the molecular structure, purity, and performance stability of phenolic resins are crucial to the yield of downstream microelectronics manufacturing and other processes. The production of this type of resin is typically carried out in a temperature-controlled reactor, where precise temperature control and material mixing are used to achieve the polymerization reaction of specific chemical molecules.

[0003] In traditional production processes, the raw materials fed into the reactor are often in the form of lumps or granules. When these unevenly shaped raw materials are directly added to the reactor, they tend to agglomerate or settle inside the reactor due to their small specific surface area and poor dispersibility, resulting in insufficient contact with the liquid raw materials.

[0004] Insufficient contact and mixing directly lead to low heat and mass transfer efficiency within the reaction system, potentially causing overheating or insufficient reaction in localized areas. This not only prolongs the entire reaction cycle but, more seriously, results in a wide molecular weight distribution and inconsistent performance of the final phenolic resin product, making it difficult to meet the high standards and stringent requirements of photoresist applications.

[0005] Therefore, this utility model proposes a temperature-controlled reaction vessel for the production of photoresist phenolic resin to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problem that in the existing technology, the temperature-controlled reactor for the production of photoresist phenolic resin is prone to insufficient mixing and reaction due to the uneven shape of the raw materials when processing block or granular raw materials, which affects the product quality, the present invention aims to provide a temperature-controlled reactor for the production of photoresist phenolic resin with an improved structure that can pre-treat the raw materials and improve the reaction uniformity.

[0007] This utility model provides a temperature-controlled reaction vessel for the production of photoresist phenolic resin, including: a reaction vessel mechanism, a motor, a connecting shaft installed on the top of the reaction vessel mechanism, a vertically inserted shaft inside the reaction vessel mechanism and connected to the motor for transmission, and a filter screen fixed inside the reaction vessel mechanism; it also includes a roller, grinding teeth and a connecting rod.

[0008] The filter screen divides the reactor into an upper feeding zone and a lower reaction chamber. The roller is rotatably positioned in the feeding zone and above the filter screen. The outer periphery of the roller is equipped with integrated grinding teeth.

[0009] Furthermore, the motor is driven by a connecting shaft, and the upper end of the connecting shaft is connected to a roller to grind the raw materials. At the same time, the connecting rod is fixed to the rod body located inside the reaction chamber of the connecting shaft to stir the materials inside the reaction chamber.

[0010] Preferably, the temperature-controlled reactor for producing photoresist phenolic resin further includes a connecting box, a connecting pipe, a filter cylinder, a rotating rod, a swivel blade, and a connecting plate. The liquid inlet of the connecting box is connected to the bottom of the reaction chamber through the connecting pipe. The filter cylinder is vertically installed inside the connecting box. The rotating rod rotates through the center of the filter cylinder. The swivel blade is fixed to the upper end of the rotating rod and located below the liquid inlet of the connecting box. The connecting plate is fixed to the rotating rod and abuts against the inner wall of the filter cylinder.

[0011] Preferably, the temperature-controlled reactor for producing photoresist phenolic resin further includes a first valve and a second valve, the first valve being located on the connecting pipe and the second valve being located at the bottom of the connecting box.

[0012] Preferably, the inner wall of the reaction chamber of the reactor mechanism is provided with heating wires.

[0013] Preferably, the reactor mechanism is also provided with a feed inlet at the top of the feeding zone.

[0014] Preferably, the temperature-controlled reactor for producing photoresist phenolic resin further includes a connecting frame, which is fixed to the top of the reactor mechanism, and the motor is mounted on the connecting frame.

The support plate is fixedly connected to the outer wall of the reactor mechanism, and the support feet are fixedly connected to the bottom surface of the support plate.

[0016] Preferably, in addition to the support plate, a fixing plate is also included, with the fixing plate fixedly connected to the bottom of the support plate and the connecting box fixed to the fixing plate.

[0018] 2. In this utility model, by setting up a swing blade, a rotating rod and a connecting plate driven by the impact of the product fluid in the filter assembly, the self-cleaning scraping of the inner wall of the filter cartridge is realized, which solves the problems of easy clogging of the filter screen by resin materials, low filtration efficiency and frequent shutdown for cleaning in the prior art, and achieves the technical effects of ensuring filtration permeability, extending the filtration cycle and improving production continuity and efficiency.
