Problems solved by technology

[0005] (3) The multi-tubular filter has many seams, and it is not easy to adopt a processing method. If high-precision robot technology is used, the investment cost is very high;
[0006] (4) When the filter tube is large, it is necessary to separately install a metal frame to increase the strength, which will further increase the cost;
[0007] (5) If it is a folded filter element, although the filtration area per unit volume is increased, it is very difficult to backwash, and generally it can only be used once, and it can only be replaced when the temperature reaches a certain level.
[0010] (1) The processing technology is complex and there are many consumables, it is not easy to use automatic processing, the cost is high and the output per unit time is low;
[0011] (2) There are many seams, not only the processing process is complicated, but the seams will also affect the filtration flow area;
[0012] (3) The unit filtration volume is large and the filtration efficiency is low;
[0013] (4) The energy required for backwashing is large, and the backwashing system is complex

Embodiment 1

[0076] see figure 1 , the present invention discloses a structural schematic diagram of a spiral plate filter system, such as figure 1 : It includes a spiral plate filter element 1, a check valve 2, a filter housing 3, a controller 4, a water purification solenoid valve 5, an unfiltered water solenoid valve 6, a sewage solenoid valve 7, a backwash solenoid valve 8, and an air pump 9.

[0077] see figure 1 with figure 2 , the spiral plate filter element 1 is processed by rolling up two pieces of filter material 1.1, and a number of support columns 1.2 are embedded between the two pieces of filter material 1.1 to maintain the distance between the two pieces of filter material, and at the same time have a reinforcement The function of the filter core is that a sealing strip 1.3 is installed on the top of the filter core to prevent unfiltered water from entering the upper water purification area, and a sealing strip 1.3 is installed on the bottom of the filter core to prevent f...

Abstract

The invention discloses a spiral plate filter system and method. The filter system includes: a spiral plate filter element, a check valve, a filter shell, a controller, a water purification solenoid valve, an unfiltered water solenoid valve, a sewage discharge solenoid valve, The backwash solenoid valve and the air pump; the controller is respectively connected to the water purification solenoid valve, the unfiltered water solenoid valve, the sewage solenoid valve, the backwash solenoid valve, and the air pump; the unfiltered water solenoid valve and the backwash solenoid valve are respectively connected to the air pump. The spiral plate filter system and method proposed by the present invention give full play to the material characteristics of the metal membrane filter, which can be conveniently welded and bent arbitrarily, and have high filtration accuracy; the processing technology of the filter system is simple, it is easy to realize automatic process production, the processing efficiency is high, and the processing cost is low. Low; filter strength is high, suitable for use in large differential pressure or high temperature environments; high filtration efficiency per unit volume, large filtration capacity, the same filtration capacity is only 1 / 5 of the volume of ordinary multi-tube filters.

Description

technical field [0001] The invention belongs to the technical field of filters, and relates to a filter system, in particular to a spiral plate filter system; meanwhile, the invention also relates to a spiral plate filter method. Background technique [0002] The filter is a kind of equipment widely used in daily life and industrial process. The key part of the filter is the filter element. The structural forms of the filter elements currently on the market are cylindrical (including conical, folded), flat Mode. For simple coarse filtration, there are many flat filter elements or single-tube filter elements, and for fine filtration, multi-tube filters are used, that is, the structural form of the filter composed of circular tube filter elements installed in a large container. Its structure is similar to Shell and tube heat exchanger. The filter equipment with this structure has the advantages of independent filter elements, which can be replaced separately and conveniently...
