Description
Technical Field

Background
In sewage treatment equipment, particularly high-pollution water film separation treatment equipment with harsh running environment, a guide disc is one of essential basic components, and the main function of the guide disc is to guide the flow direction of liquid in the sewage treatment equipment so as to realize separation of concentrated liquid and clear liquid. The center of traditional membrane column water conservancy diversion dish is open through the liquid sealing strip, relies on the sealing washer to seal completely, and when the pressure differential was too big in sealing washer both ends, the sealing washer will remove, causes the permeate to mix with the stoste, influences concentration, purification effect.
Chinese patent CN205868027U (application number: 201620545188.2, publication date: 2017, 1/11) discloses a disc tubular membrane column flow guide disc, please refer to fig. 1, which comprises a flow guide disc body 10, a pull rod hole 20 is formed at the center of the flow guide disc body 10, the upper end surface of the outer edge of the pull rod hole 20 protrudes upwards to form an annular boss 30, the bosses 30 at the outer edge of the pull rod hole 20 are arranged at intervals, a water purifying collecting tank 80 for purifying water collection is arranged between every two adjacent bosses 30, the water purifying collecting tanks 80 are uniformly distributed, the depth of the water purifying collecting tank 80 in the radial direction is equal to the width of the boss 30 in the radial direction, an annular groove 70 is formed by inwards recessing the lower end surface of the outer edge of the pull rod hole 20, a plurality of positioning pins 40 are uniformly distributed around the upper surface of the boss 30, a plurality of positioning holes matched with the positioning pins 40 are formed in the annular groove 70, a plurality of through grooves 50 are formed around the axis of the flow guide disc along the radial direction of the flow guide disc, and the outer edge of the boss 30 is simple in structure, easy processing, good sealing performance and easy maintenance are easy.
However, since the water purifying circuit is usually formed by assembling the laminated guide plates, the laminated guide plates are assembled by axially requiring the positioning pins 40 and the positioning holes. If not positioned, random angular deflection of the product occurs during assembly of the stack. If the deflection angle exceeds a certain value, the boss 30 is aligned with the purified water collecting groove 80 of the other flow guiding disk in the axial direction, the flow of purified water in the purified water collecting groove 80 is blocked, the parts assembled by lamination cannot form a clear purified water loop, and the purified water cannot be smoothly discharged. That is, when the laminated assembly is generally performed, the guide plates are rotated until the positioning pins 40 are opposite to the positioning holes, and for convenience of observation, positioning protruding points are generally disposed on the outer circumferences of the guide plates, for example, when the positioning protruding points of the two guide plates are rotated to the same axial direction, the positioning pins 40 are confirmed to be opposite to the positioning holes at this time, and then the positioning pins 40 are inserted into the positioning holes for axial positioning.
The two processes of positioning and positioning confirmation are required for lamination assembly, which causes time and labor consumption in lamination assembly. And if misalignment occurs, the locating pin 40 cannot enter the locating hole, and then the part is scrapped when the fastening screw is tightened. In addition, the disassembly and sorting of the laminated assembled diaphragm assembly requires a great deal of labor.
