Description

Paint oil filter

Technical Field

The invention relates to the technical field of paint oil processing equipment, in particular to a paint oil filter.

Background

The lacquer oil, also called lacquer seed oil, is liquid dry oil with high melting point and low iodine value extracted from lacquer seed kernel, has greasy feeling when being touched by hand, and is a good natural vegetable oil source. Compared with petroleum, the lacquer oil has the advantages of no toxicity, no pollution and the like, and is a superior raw material in industries of lightening, electronics and the like. The lacquer oil contains more than 60 percent of unsaturated acids such as oleic acid, linoleic acid and the like, is an excellent health-care oil product, and can also be industrially applied to the fields of medicines, health care, foods, cosmetics and the like. The edible lacquer oil is used in the minority nationality area of Yunnan, and various medicines prepared from the edible lacquer oil have good curative effects on reducing cholesterol, preventing and treating coronary heart disease, inhibiting tumor growth, resisting bacteria and diminishing inflammation and the like.

The lacquer tree in China is rich in resources and various in varieties, and is mainly prepared from raw lacquer and processed lacquer seeds as auxiliary materials. However, the metal mesh is adopted to filter the paint oil in the processing process, so that fine colloids and impurities cannot be filtered, the colloids and the impurities are often remained, the appearance quality, the storage characteristic and the application effect of the paint oil are influenced, and the popularization of the paint oil and paint oil products is influenced.

Disclosure of Invention

The invention aims to provide a paint oil filter to solve the problems in the prior art and improve the filtering effect of paint oil.

In order to achieve the purpose, the invention provides the following scheme:

the invention provides a paint oil filter which comprises an oil pump and a sealed cabin, wherein an oil outlet of the oil pump is communicated with an oil inlet of the sealed cabin through an oil conveying pipe, and a plurality of paper-cloth composite filters are arranged in the sealed cabin at intervals along the vertical direction; the paper-cloth composite filter comprises a rectangular support frame, a paper layer is laid on the top surface of the rectangular support frame, cloth layers are arranged on the top surface and the bottom surface of the rectangular support frame, and the junction of the cloth layers and the paper layer is in sealing connection; and the side wall of each paper-cloth composite filter is tightly attached to the inner wall of the sealed cabin.

Preferably, the oil conveying pipe is provided with an automatic pressure control valve and a pressure gauge.

Preferably, the oil inlet of the sealed cabin is arranged at the top end of the sealed cabin, and the oil outlet of the sealed cabin is arranged at the bottom of the sealed cabin.

Compared with the prior art, the invention has the following technical effects:

the paint oil filter press has good filtering effect. The paint oil filter press is separated by a paper-cloth composite filtering system consisting of a plurality of paper-cloth composite filters in a sealed cabin, paint oil is input into a filtering tank in the sealed cabin by an oil pump, and when the pressure in the tank reaches a pressure threshold value, the paint oil flows through a paper-cloth filtering membrane along the pressure direction, so that the aim of removing paint oil colloid and impurities is fulfilled, and the appearance quality and the internal quality of the paint oil are improved.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
