Strainer plate flow-guiding channel forming structure and forming method thereof

Abstract

The invention relates to a forming structure of a filter plate flow guide channel and a forming method, a liquid outlet hole or a washing hole and a liquid outlet channel or a washing flow guide channel are arranged on a filter plate, and the liquid outlet channel or the washing flow guide channel which is positioned in the filter plate is a flow guide pipe. The forming structure of the filter plate flow guide channel has the advantages that: firstly, the drilling of the hole on the filter plate is not needed, then the accurate positioning of the flow guide channel is obtained, and the liquid outlet channel or the washing flow guide channel has smooth flow guide wall, so as to solve the problems of poor accuracy, poor wall smoothness, big flow rate resistance and easy attachment of the fiber impurities of the processing of the flow guide channel of the background technology; secondly, the working efficiency of the whole machine is improved due to the high flow rate; thirdly, as the liquid outlet channel or the washing flow guide channel does not need the secondary process, thereby greatly reducing the processing cost and the processing cycle of the filter plate, and improving the production efficiency.

Description

technical field [0001] The invention relates to a forming structure and a forming method of a flow guide channel of a filter plate, belonging to the field of filter plate manufacturing for filter presses. Background technique [0002] Patent No. 01123504.7, titled "Filter plate process hole sealing method", the filter plate process hole sealing method, the filter plate (3) is equipped with one or more process holes (1), liquid outlet or washing hole (2) and the liquid outlet or washing hole (4), the process hole (1) is connected with the liquid outlet or washing hole (2), and the liquid outlet or washing hole (4) is connected with the process hole (1) , the tapered rod (8) blocks the process hole (1) from the inside to the outside from the liquid outlet or washing hole (2). Its disadvantages: one, in order to obtain liquid outlet or washing hole (drain channel), the background technology needs to drill holes from the side of the filter plate to make liquid outlet or wash di...

AI Technical Summary

Problems solved by technology

Its disadvantages: one, in order to obtain liquid outlet or washing hole (drain channel), the background technology needs to drill holes from the side of the filter plate to make liquid outlet or wash diversion channel, which not only wastes materials, but also cannot ensure the flow guide channel. The accuracy of the position of the flow channel; the second is to use the diversion channel obtained by drilling, the smoothness of the guide channel wall is very rough, which directly affects the flow rate of the squeezed liquid

What's more serious is: because the liquid produced by pressing contains a lot of foreign fibers, it is very easy to adhere to the wall of the diversion channel, which greatly reduces the speed of fluid diversion and directly affects the working efficiency of the whole machine; No matter what method is used to fill the drilling holes on the wall of the filter plate, they cannot reach the level before the holes are opened. Secondly, the filled drilling holes need to be processed twice, which increases the processing cost and cycle time of the filter plate.
