Problems solved by technology

There are still some deficiencies in the use of this pleated filter element, which are mainly manifested in: 1. The filter layer adopts pleated polypropylene membrane, the filter hole is a straight through hole, the filter layer is thin, and the filtration accuracy is unstable; 2. It cannot be backwashed, because The inside and outside of the filter layer are blocked by a mesh skeleton, and the folding gap of the membrane is relatively deep, which makes it inconvenient to wash. When the working pressure is too high, it will cause the filter layer to rupture or perforate. backwash, not reusable

Embodiment Construction

[0020] Prepare the rod filter element according to the following process steps:

[0021] First, according to the filter pore size requirements of the product to be obtained, use molecular sieves to screen out the required ultra-high molecular polyethylene or high-density polyethylene raw materials with different pore sizes. For example, to make a filter rod with a filter pore size of 0.2 μm, ultra-high molecular polyethylene or high-density polyethylene with a particle size of 60-400 mesh and a molecular weight of 1.5 million-3 million units can be selected. In addition, in order to enhance the uniformity of the filter pore diameter, 4-5% of auxiliary material polyfluorotetrachloroethylene can also be added, and the mold can be loaded after mixing and stirring evenly.

[0022] Then, the mold that usually makes hollow rods is used as the mold for making the rod filter layer. The mold is composed of an outer mold, an inner membrane, a base and an upper cover. In order to ensure ...

Abstract

The invention discloses a wine bar-type filter element and preparing method, which comprises the following steps: arranging sinter molding super high molecule polyethylene or high density polyethylene bar-type filter element layer in the middle; fritting inserter and fin separately; sticking and fixing on the two end; sieving raw material; allocating; die-filling; caking; cooling; demoulding; assembling; getting the product. This bar-type filter element possesses higher catching ratio and stable filtering accuracy, which can proceed backward and forward flush.

Description

technical field [0001] The invention belongs to the technical field of filtering equipment. Background technique [0002] The current wine filtration equipment usually uses pleated filter elements or PE rods as the key components of filtration, and the rod type filter element is gradually favored by the market due to its large flux, low cost, easy installation and cleaning operation. The existing pleated filter element used on the market basically has the following structure: it is a rod, with a plastic mesh support layer inside and outside, a pleated membrane filter layer of polypropylene in the middle, and inserts and fins bonded at both ends. There are still some deficiencies in the use of this pleated filter element, which are mainly manifested in: 1. The filter layer adopts pleated polypropylene membrane, the filter hole is a straight through hole, the filter layer is thin, and the filtration accuracy is unstable; 2. It cannot be backwashed, ...
