Problems solved by technology

For such a frame structure, since the ventilation hole is opened in the later stage of the frame, the glass fiber in the original frame is cut off, so that the glass fiber filament is no longer in a continuous state, which greatly reduces the strength of the frame, and at the same time, the processing is more cumbersome. Porosity is also low

preparation example Construction

[0040] A method for preparing a fiberglass filter element skeleton, comprising the steps of:

[0041] In the first step, glass fiber filaments are soaked in resin, and then converged into glass fiber strips;

[0042] In the second step, the resin-soaked glass fiber strips are wound on the mold to form a fiberglass filter core skeleton, and the glass fiber strips are continuously staggered, and ports 22 are left;

[0043] The third step is to solidify the wound mesh FRP filter skeleton;

[0044] The fourth step is demoulding.

[0045] In Step 3, the curing is at natural temperature for 45-60 minutes; or hot air curing, the curing temperature is 50-55° C., and the curing time is 15-20 minutes.

[0046]In step 2, the mold is a cylindrical mold 1, and the surface of the mold 1 is distributed with interlaced embedding grooves, the embedding grooves include axial grooves and circumferential grooves, and the axial grooves are evenly distributed around the mold 1, The circumferenti...

Abstract

The invention discloses a glass-reinforced-plastic filter element framework. The glass-reinforced-plastic filter element framework is formed through integral curing of glass fiber curing ribs in continuously staggered arrangement. A preparation method of the glass-reinforced-plastic filter element framework is characterized by including, step 1, soaking glass fiber filaments in resin, and formingfiber glass strips after gathering; step 2, winding the glass fiber strips infused with the resin around a mold to form the glass-reinforced-plastic filter element framework, wherein the glass fiber strips are arrangedin a staggered mode and are provided with ports; step 3, curing the meshed glass-reinforced-plastic filter element framework; step 4, performing de-molding. The glass-reinforced-plastic filter element framework has the advantages that the glass-reinforced-plastic filter element framework is convenient to process due to integral forming; glass fibers are arranged in the frameworkcontinuously, and the strength of the framework is improved greatly; no waste materials are generated; through continuity of the glass fibers, forming area of air holes can be increased, and accordingly, transparency is improved.

Description

technical field [0001] The invention relates to a frame of a glass fiber reinforced plastic filter element and a manufacturing method thereof. Background technique [0002] Existing fiberglass filter element framework generally comprises a cylindrical frame body, and then a plurality of circular air holes are opened on the cylindrical frame body, and the air holes are formed by the cylindrical frame body in a double-layer cylinder mould. Firstly, the tubular FRP embryo body is formed, and then a round hole is opened on the FRP embryo body. For such a frame structure, since the ventilation hole is opened in the later stage of the frame, the glass fiber in the original frame is cut off, so that the glass fiber filament is no longer in a continuous state, which greatly reduces the strength of the frame, and at the same time, the processing is more cumbersome. The porosity is also low. In the prior art, there is an urgent need for a fiberglass filter element framework with hig...
