Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and is a device for improving the filtration effect of dimethicone oil. Background Technology

[0002] Dimethyl silicone oil is an organosilicon polymer made from DMC (cyclosiloxane) as a raw material, combined with a specific catalyst, through reactions such as heating, dehydration, polymerization, and dehydration. Dimethyl silicone oil has physiological inertness, good chemical stability, heat resistance, thermal conductivity, and its viscosity changes little with temperature. Based on these unique physicochemical properties, it is widely used in many fields such as daily chemicals, pharmaceuticals, and industrial production.

[0003] Current dimethyl silicone oil production involves polymerizing raw materials such as DMC and catalysts in a polymerization reactor at high temperature. After polymerization, the material is transferred to an intermediate tank for buffering, and then enters a scraped evaporator for descaling. After descaling, the dimethyl silicone oil is cooled and then enters a finished product storage tank. In the current process, a single-bag filter is installed on the pipeline from the descaling stage to the finished product storage tank to filter impurities generated during pipeline transportation, ensuring stable dimethyl silicone oil quality. However, current single-bag filters have drawbacks such as small filtration area, low filtration efficiency, and poor filtration effect. Summary of the Invention

[0004] This invention provides a device for improving the filtration effect of dimethicone oil, overcoming the shortcomings of the prior art, and effectively solving the problems of small filtration area and low filtration efficiency of existing single-bag filters.

[0005] The technical solution of this utility model is achieved through the following measures: A device for improving the filtration effect of dimethicone oil includes a tank body, a top cover that is detachably installed on the top of the tank body, a partition plate that divides the tank body into an upper cavity and a lower cavity is fixed in the upper part of the tank body, a feed pipe that communicates with the upper cavity is fixed on the partition plate, the feed inlet of the feed pipe is located outside the tank body, a number of filter holes are arranged at intervals along the front-back direction on the partition plate, a filter bag is fixed at each filter hole, the filter bag is located in the lower cavity, and a discharge pipe is fixedly connected to the bottom of the tank body, the discharge outlet of the discharge pipe is located outside the tank body.

[0006] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution:

[0007] An opening mechanism can be fixed to the outside of the tank. The opening mechanism includes a horizontal connecting rod, a vertical support rod, and a hinge rod. At least two horizontal connecting rods are fixedly connected at intervals along the vertical direction on the outside of the tank.
