Abstract

A rapid forming method of a filter includes a material preparation step, a mixing step, a spraying step, a preliminary forming step, and a forming step. The mixing step is to mix a polymer fiber material prepared in the material preparation step with a certain proportion of water by a stirring unit to obtain a slurry material. The spraying step is to spray the slurry material over cavities of an upper mold and a lower mold. The preliminary forming step is to discharge redundant water and gas by a vacuum unit during the spraying operation to thereby gradually form the slurry material into an embryo filter. The forming step is to release the molds and maintain the embryo filter to obtain the finished filter. Hence, the continuous rapid forming process can increase the production efficiency effectively.

Description

Filter rapid prototyping method

The invention relates to a filter manufacturing process, in particular to a filter rapid forming method.

According to investigations, when power plants or large-scale industrial manufacturing plants are in operation, they will produce too much exhaust gas, and the exhaust gas produced at the same time will contain many gaseous pollutants. Therefore, in order to prevent the exhaust gas from polluting the environment and human body Health causes harm. Therefore, in environmental protection regulations, all waste gas produced by industrial manufacturing plants must be treated before it can be discharged outside. The dust and dust in the exhaust gas are isolated and the exhaust gas is purified, so it is known that a fiber filter bag will be installed on the filter system for treating exhaust gas, and the exhaust gas generated during manufacturing will be sucked in by the exhaust device of the filter system. , through the outside of the fiber filter bag to enter the inner filter, so that the dust and dust in the exhaust gas can be effectively isolated from the fiber filter bag to achieve the effect of industrial waste gas filtration.

However, it was found that although the fiber filter bag can be used to filter industrial waste gas, due to the limitation of the thickness and density of the overall structure of the fiber filter bag during use, it can only be used for large particles in industrial waste gas. Dust and dust are effectively isolated from the outside, but for light and tiny particles, they cannot be blocked and filtered by the fiber filter bag, and they will still be fused into the air after filtering, and the filtering effect still needs to be improved.

Therefore, the purpose of the present invention is to provide a filter rapid forming method This method can simplify the process and quickly form a filter made of fiber material, effectively improving production efficiency.

Therefore, a filter rapid forming method of the present invention includes a material preparation step, a mixing step, a spraying step, a preliminary forming step and a forming step in sequence; raw material, and add 2 to 150 times of water based on the fiber polymerization raw material, mix and stir to form a slurry, and the spraying step is equipped with a discharge unit and a molding die, the discharge unit accepts the slurry and sprays it Spray on the cavity of the upper and lower molds of the forming mold, and at the same time cooperate with the vacuum unit equipped in the preliminary forming step to discharge excess water and gas in the slurry in the forming mold, so that the slurry The body is gradually formed into a filter prototype, and finally the filter prototype obtained in the preliminary forming step is demoulded and maintained through the forming step to form a filter; therefore, through the consistent rapid continuous In the manufacturing process, the mixing step is used to stir and mix into a slurry, and then the spraying and preliminary forming steps are used to form the slurry in an evenly staggered manner along the shape of the molding mold through the spraying method, and then aim at the moisture in the slurry It is separated from the gas, so that the prototype of the filter can be quickly formed, and then through the demoulding and maintenance procedures of the forming step to form a filter, which can not only quickly achieve forming, but also effectively improve the quality of filter forming production , and increase production efficiency.
