Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic-grade chemicals technology, specifically a stirring reaction apparatus for the preparation of electronic-grade chemicals. Background Technology
[0002] Electronic-grade chemicals refer to chemical reagents whose main components have a purity greater than 99.99% and whose impurity ions, especially impurity cations and particle numbers, meet strict requirements. They mainly include hydrochloric acid, acetone, ultrapure water, isopropanol, etc.
[0003] Electronic-grade chemicals require reaction equipment during manufacturing, but existing reaction equipment is relatively simple and lacks comprehensive functionality.
[0004] For example, Chinese patent CN221245220U discloses a reactor for electronic-grade chemical reactions. By using a stirring paddle, the chemicals inside the reactor can be stirred to increase the reaction rate. At the same time, the stirring column can be rotated in the opposite direction by a motor, and the stirring column drives the entire inner reactor to rotate, which has a certain centrifugal separation effect.
[0005] However, the equipment is difficult to clean after the reaction is complete, and impurities are easily left behind, affecting the quality and effect of the next production. Utility Model Content
[0006] The purpose of this invention is to provide a stirring reaction apparatus for the preparation of electronic-grade chemicals, in order to solve the problem mentioned in the background art that the apparatus is difficult to clean after the reaction is completed, easily leaving impurities, which affects the quality and effect of the next production.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a stirring reaction apparatus for the preparation of electronic-grade chemicals, comprising a frame and a stirring cylinder, wherein the stirring cylinder is fixedly installed inside the frame, a stirring device is provided inside the stirring cylinder, and a cleaning device is provided above the stirring cylinder;
[0008] The stirring device includes a stirring motor, a stirring shaft, alternating blades, and a support rod. The stirring motor is mounted on the top of the frame, the stirring shaft is connected to the output end of the stirring motor, the support rod is fixedly connected to the outer surface of the stirring shaft, and the alternating blades are fixedly connected to the top of the support rod. By starting the stirring motor, the stirring shaft is driven, and the support rod rotates with the stirring shaft, thereby causing the alternating blades to rotate around the stirring shaft as the axis to achieve the purpose of stirring.
[0009] The cleaning device includes a valve, a cleaning straight pipe, a nozzle, a diamond-shaped pipe, a large gear, a small gear, and a rotating shaft. The large gear is fitted onto the outer surface of the stirring shaft. The diamond-shaped pipe has four through holes at its top, through which the rotating shaft passes. The nozzle is fixedly connected to the bottom of the rotating shaft. The small gear is fitted onto the outer surface of the rotating shaft and contacts the large gear. The diamond-shaped pipe is fixedly installed above the stirring drum. The cleaning straight pipe is fixedly connected to the right side of the diamond-shaped pipe. The valve is fixedly connected between two cleaning straight pipes. The cleaning straight pipe is connected to a container containing cleaning liquid. When the valve is opened, the cleaning liquid is sprayed out from the nozzle through the cleaning straight pipe and the diamond-shaped pipe. Turning on the stirring motor drives the large gear to rotate, which in turn drives the small gear to rotate, causing the rotating shaft to rotate, thereby rotating the nozzle to achieve the purpose of all-round spraying cleaning.
[0010] Preferably, a threaded hole is provided on the top of the frame, and the stirring motor is threadedly connected to the frame bolt through the threaded hole. This connection method makes the installation and disassembly of the stirring motor simple and quick, and facilitates maintenance and replacement. At the same time, the threaded connection also provides good stability and firmness, ensuring the stable operation of the stirring motor during the working process and reducing the risk of failure caused by vibration or loosening.
[0011] Preferably, the bottom of the mixing drum is conical, and a discharge port is provided at the bottom of the mixing drum. A sealing ring is fitted over the discharge port, and the outer surface of the discharge port is threaded. A sealing cap is connected to the outer surface of the discharge port through the thread. The conical bottom design facilitates the smooth discharge of materials and reduces the possibility of residue and blockage. The design of the discharge port and the sealing cap not only ensures the convenience of material discharge, but also effectively prevents material leakage when not in use, ensuring the cleanliness and safety of the production environment.
[0012] Preferably, a conveying device is provided on the right side of the mixing drum; the conveying device includes a water pump, a conveying pipe, a base, a raw material tank, and a sealing ring. The base is fixedly connected to the upper right side of the frame, the water pump is installed above the base, and the conveying pipe is fixedly connected to the left and right sides of the water pump. A through hole is opened on the right side of the mixing drum, and the through hole is fixedly connected to the left end of the conveying pipe. The right end of the conveying pipe is threaded, and the sealing ring is fitted onto the right end of the conveying pipe. A connecting pipe is opened on the left side of the raw material tank, and the right end of the conveying pipe is threadedly connected to the connecting pipe. Most chemical raw materials are corrosive or polluting. Directly drawing the raw material liquid into the mixing drum by the water pump can prevent raw material leakage and avoid direct contact with personnel, reducing the occurrence of accidents and pollution.
[0013] Preferably, a threaded hole is provided on the upper part of the base, and the water pump is threadedly connected to the upper part of the base through the threaded hole. This installation method makes the water pump more secure and reliable, reduces loosening and failure caused by vibration, and at the same time, the threaded connection facilitates the maintenance and replacement of the water pump, improving the overall reliability and service life of the equipment.
[0014] Preferably, the material of the raw material barrel is polypropylene (PP), which has excellent corrosion resistance and can resist the erosion of a variety of chemicals. It is suitable for the storage and transportation of liquid chemicals. In addition, polypropylene is relatively inexpensive, which reduces production costs. Therefore, choosing polypropylene as the material of the raw material barrel ensures both product quality and safety and economic benefits.
[0015] Preferably, the front of the mixing drum is provided with a threaded hole, and a monitoring instrument is fixedly installed on the front of the mixing drum through the threaded hole. The installation of the monitoring instrument allows the operator to understand the status and parameters of the material in the mixing drum (such as temperature, pressure, liquid level, etc.) in real time, providing an important basis for the control and adjustment of the production process. At the same time, the fixing method of the monitoring instrument also ensures its stability and accuracy, and improves the reliability of the monitoring data.
