Description

Manufacturing method of bacteria culture filter

The present invention relates to a manufacturing method of a bacterial culture filter material.

According to the press, bacteria culture filter material has been widely used in water quality filtration optimization equipment, as the filtration of water quality and the cultivation of beneficial bacteria, because sewage can not only be filtered and purified, but must also be cultured through beneficial bacteria, such as nitrifying bacteria, etc., The microorganisms after culturing are used to digest and optimize harmful substances such as nitrate and nitrite produced in aquaculture, as long as the water quality can be filtered and the environment for the growth of beneficial bacteria can be provided.

The filter material is made of countless irregular thin strips of thermoplastic. The plastic filaments are stacked and entangled with each other to form a three-dimensional gap, which can be used for microorganisms such as beneficial bacteria to attach and parasite, and decompose the organic matter contained in the sewage. In addition to having an excellent function of filtering sewage, it can also obtain good biological decomposition. Effect. However, because the filter material is a long and flat plate, in order to be convenient to use in various pools or filtration environments, it is necessary to further use processing equipment, such as a hot press molding machine, to heat the filter material to form a suitable size. The bacteria-cultivating filter material in the same shape can be conveniently placed in the pool or in the environment where water quality needs to be filtered, so as to improve and optimize the water quality, and it does not need to increase the equipment expenditure.

In view of this, after observing the above-mentioned shortcomings, the inventor of this case, based on years of professional development and production experience in related industries, upholds the spirit of excellence, and devoted himself to research and improvement, and thus came up with the present invention.

The purpose of the present invention is to provide a method for manufacturing a bacteria-cultivating filter material, which can complete the whole process at one time on the same production line, and has the advantages of saving labor, time and energy.

In order to achieve the above-mentioned purpose, the manufacturing method of the bacteria-culturing filter material provided by the present invention comprises the following steps:

Material preparation steps: prepare plastic raw materials, heat the plastic raw materials to a molten slurry, and put the plastic materials into an extruder; spinning step: extrude the molten slurry onto a spinning head, so that the slurry passes through The spinning head hangs down naturally to form a plurality of plastic filaments; the forming step: making the plastic filaments hang down between two forming wheels, wherein the forming wheels are abutted against each other and rotate in opposite directions respectively, and the The surfaces of the forming wheels are respectively provided with a plurality of concave dies, and the plastic threads hang down on the forming wheels to be intertwined with each other, and are rolled and formed through the forming wheels and the concave dies to form a plurality of bacterial cultures. Filter material prototype; Cooling step: The bacteria-cultivating filter material prototypes are then hung down, cooled and formed in a water tank, and then placed on a conveyor belt for subsequent processing directly; Drying step: Passing a drying device Dry the prototypes of the bacteria-culturing filter material; cutting step: cut the bacteria-culturing filter material prototypes through a cutting device: Finished product: After being completely dried and hardened, the bacteria-culturing filter material can be obtained.

The manufacturing method of the bacteria-cultivating filter material of the present invention is that it is formed by rolling at high temperature, and then subsequent processing such as cutting is performed, whereby the entire manufacturing process can be completed at one time on the same production line, thereby saving labor, time and energy.
