Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating oil production technology, specifically to a blending equipment for insulating oil production and processing. Background Technology
[0002] The processing steps for insulating oil are as follows: Purchase insulating oil raw materials; then filter and remove impurities from the insulating oil raw materials to ensure purity; next, perform deep processing on the purified insulating oil raw materials to form finished insulating oil products; then test and inspect the processed finished insulating oil products, including breakdown voltage, dielectric loss, viscosity, moisture, acid value, etc.; finally, store and package the finished insulating oil products for later transportation and use.
[0003] When insulating oil raw materials undergo deep processing, it is generally necessary to add antioxidant additive particles to blend the insulating oil raw materials and antioxidant additive particles together to improve the antioxidant properties of the finished insulating oil product. Therefore, it is necessary to use blending equipment suitable for deep processing of insulating oil raw materials.
[0004] Existing blending equipment for insulating oil production has been found to have shortcomings during use. It cannot effectively crush and break down antioxidant additive particles adhering to the inner wall of the blending tank or deposited at the bottom, resulting in insufficient participation of these particles in the blending process. Therefore, optimization and improvement are necessary. Summary of the Invention
[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and to provide a blending equipment for the production and processing of insulating oil.
[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:
[0007] A blending device for producing and processing insulating oil includes a blending tank. The top plate of the blending tank is equipped with a first feed pipe for feeding insulating oil raw materials and a second feed pipe for feeding antioxidant additive particles. A discharge pipe is installed on the side of the blending tank near the bottom. A stirring motor is fixed to the outer wall of the top plate of the blending tank via a bracket. The output end of the stirring motor is connected via a coupling to a stirring shaft extending into the inner cavity of the blending tank. Several stirring blades are installed on the outer side of the stirring shaft. A side crushing assembly capable of crushing and breaking down the antioxidant additive particles adhering to the inner wall of the blending tank is also installed on the outer side of the stirring shaft. A receiving tray is installed on the bottom side of the inner cavity of the blending tank, and a bottom crushing assembly capable of crushing and breaking down the antioxidant additive particles deposited on the receiving tray is installed at the bottom of the stirring shaft.
[0008] Furthermore, in the above-mentioned blending equipment for insulating oil production and processing, there are three stirring blades arranged in layers. The three stirring blades are used to stir the upper, middle and lower regions of the blending box cavity, respectively. The stirring blades are evenly distributed with through holes to reduce the suction effect.
[0009] Furthermore, in the above-mentioned blending equipment for producing and processing insulating oil, the installation position of the side rolling assembly is staggered from the installation position of each stirring blade.
[0010] Furthermore, in the above-mentioned blending equipment for insulating oil production and processing, the side rolling assembly includes a first support column, a connecting rod, a first compression spring, a second support column, a first roller seat, and a first roller. There are two first support columns connected together by the connecting rod. One end of each first support column is fixed to the stirring shaft, and the other end of each first support column is provided with a snap-fit groove. One end of the second support column is slidably restricted in the snap-fit groove. A first compression spring is pre-installed in the snap-fit groove. The other end of the second support column is supported by a support frame to support the first roller seat. The first roller seat movably supports a first roller that is height-matched to the inner cavity of the blending box.
[0011] Furthermore, in the above-mentioned blending equipment for insulating oil production and processing, a positioning rotating sleeve that mates with the bottom end of the stirring shaft is embedded at the center of the upper end of the receiving tray, and an annular receiving groove is formed around the positioning rotating sleeve at the upper end of the receiving tray. The cross-section of the annular receiving groove is a trapezoidal structure that is wider at the top and narrower at the bottom.
[0012] Furthermore, in the above-mentioned blending equipment for insulating oil production and processing, the bottom rolling assembly includes a collar, a horizontal support plate, a second roller seat, and a second roller. The collar is sleeved on the outside of the stirring shaft, and the horizontal support plate is symmetrically installed on the outside of the collar. The second roller is movably supported on the lower side of the horizontal support plate through the second roller seat. The width of the second roller matches the bottom width of the annular receiving groove.
[0013] Furthermore, in the above-mentioned blending equipment for producing and processing insulating oil, the two side plates of the second roller seat are symmetrically provided with sliding grooves, and a sliding plate is slidably restricted in the two sliding grooves. A second compression spring is connected between the upper side of the sliding plate and the inner side of the web plate of the second roller seat, and a scraper for scraping off catalyst fragments on the lower side of the sliding plate is installed.
[0014] Furthermore, in the above-mentioned blending equipment for producing and processing insulating oil, the stirring shaft is equipped with a bottom blade plate near the bottom end to facilitate blowing up catalyst fragments.
[0015] The beneficial effects of this utility model are:
[0016] This utility model equipment is rationally designed and mainly consists of a mixing tank, a first feed pipe, a second feed pipe, a discharge pipe, a stirring motor, a stirring shaft, stirring blades, a side crushing assembly, a receiving tray, and a bottom crushing assembly. These components work together in concert. The first feed pipe is used to feed insulating oil raw materials, and the second feed pipe is used to feed antioxidant additive particles.
