Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of integrated sewage treatment equipment, and particularly relates to a one-way valve plate. Background Art
[0002] In an integrated sewage treatment box, there are multiple independent units in a sealed state. When the box is filled with water for commissioning, separate water injection ports need to be set for each independent unit to avoid situations such as the partition swelling and cracking due to the liquid level difference of the internal partition. When emptying, independent emptying ports also need to be set for each unit or a submersible sewage pump is used to evacuate one by one, which is cumbersome and laborious.
[0003] If water is continuously injected into a single unit, it is required that the internal partition of the box has a certain pressure-bearing capacity. Generally, to avoid manual operation errors, devices such as reinforcing ribs are added to the internal partition to resist deformation. However, after the box is filled with water and put into operation, each unit is in a connected state, and the partition is not stressed unidirectionally. At this time, devices such as reinforcing ribs are actually wasted and have no practical use. There is no good solution to the above problems in the prior art. Summary of the Utility Model

Specific implementation manners
[0027] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0028] As shown in Figure 4 Figure, a one-way valve plate includes a carrier plate 1, and a plurality of flow guiding holes 101 are formed in the carrier plate 1 for realizing the conduction of sewage from one independent unit to another independent unit in the sewage treatment integrated equipment.
[0029] As shown in Figures 1 - 5 Figure, a plurality of first through holes 102 are formed in the carrier plate 1, a pressing piece 2 is installed on one side of the carrier plate 1, a plurality of second through holes 201 are formed in the pressing piece 2, bolts 5 are inserted into the first through holes 102 and the second through holes 201, a pressing strip 3 is installed between the bolts 5 and the pressing piece 2, a plurality of third through holes 301 are formed in the pressing strip 3, and nuts 8 are threadedly connected to the tails of the bolts 5. In this way, the installation and use of the one-way valve plate are completed. Specifically, the pressing piece 2 can be made of nitrile rubber material, which has good water resistance, airtightness and excellent bonding performance, can ensure the working stability of the pressing piece 2, and can enable the one-way valve plate to complete the work task better. The pressing strip 3 and the pressing ring 4 can be made of stainless steel material, which has high strength and corrosion resistance, can bear large pressure, and can also increase the connection strength between the bolt and the rubber material, and can also improve the working ability of the one-way valve plate.
[0030] A plurality of convex rings 202 are provided on the pressing piece 2. The diameter of the convex ring 202 is slightly smaller than that of the diversion hole 101 so that the convex ring 202 can just be embedded into the diversion hole 101. After the integrated sewage treatment equipment is filled with water, the convex ring 202 can better ensure that the sewage treatment working environment in each independent unit is not disturbed, enabling the effective completion of each sewage treatment process; at the same time, it can also ensure to a certain extent that each independent unit can drain water successively and operate normally when the box starts to drain water.
[0031] As shown in Figure 5 the figure, a pressing ring 203 is provided on the pressing piece 2, which effectively enhances the close fit between the pressing piece 2 and the bearing plate 1 to achieve the same effect as the convex ring 202 to a certain extent. In addition, the horizontal length of the pressing ring 203 is smaller than that of the convex ring 202, so that the convex ring 202 and the pressing ring 203 can each play their roles without interference.
[0032] As shown in Figures 1 - 3 the figure, a pressure ring 4 is provided between the pressing piece 2 and the pressing strip 3. A fourth through hole 401 is provided on the pressure ring 4, so that the bolt 5 can install and fix the pressure ring 4 through the fourth through hole 401. An annular section is provided on the pressure ring 4, which is a receiving part corresponding to the lower end of the pressing piece 2. The lower part of the pressure ring 4 slightly covers the lower end of the pressing piece 2. Specifically, it is preferably 3 - 5 mm, which is a pressing part corresponding to the lower end of the pressing piece 2. The pressure ring 4 is made of an elastic material. When the box is filled with water, the sewage passes through the diversion hole 101, pushes open the pressing piece 2, and can push the lower part of the pressure ring 4, so that the lower end of the pressing piece 2 can be received into the annular section of the pressure ring 4. After the water injection is completed, the lower part of the pressing piece 2 can return to its original position under its own gravity, the water pressure and the elastic force of the pressure ring 4, which can effectively complete the sealing of the independent unit, effectively maintain the working environment of the sewage treatment bacteria in each independent unit without being affected, and enable the effective completion of each sewage treatment process.
[0033] As shown in Figure 2 and Figure 6 the figure, a frame 6 is installed between the bearing plate 1 and the nut 8, and the frame 6 abuts against the bearing plate 1. Specifically, a plurality of fifth through holes 601 are provided in the upper part of the frame 6, and the bolt 5 can install and fix the frame 6 through the fifth through holes 601. A limiting groove 602 is provided on the frame 6, and a filter screen 7 is installed in the limiting groove 602. Specifically, the shape and size of the filter screen 7 correspond to the limiting groove 602, and it can be inserted into the limiting groove 602 from above, and the upper end of the filter screen 7 does not affect the bolt 5 passing through the fifth through hole 601.
[0034] The aperture of the filter screen 7 is smaller than that of the diversion hole 101, thereby reducing the possibility of blockage of the diversion hole 101, improving the working stability of the one-way valve piece, and reducing the maintenance cost of the one-way valve piece.
[0035] During specific use, as shown in Figures 1 - 7As shown in the figure, the integrated sewage treatment box body is provided with a water injection port 01 and a drain port 02, and the bearing plate 1 divides the box body 00 into multiple independent spaces. When injecting water, the sewage entering the box body 00 passes through the diversion holes 101, squeezes open the convex ring 202, and pushes the lower part of the pressure ring 4, so that the lower part of the pressing piece 2 falls into the annular section of the pressure ring 4 to ensure the open state, and then enters another independent unit. After the water injection is completed, the lower part of the pressing piece 2 returns to its original position under its own gravity, the water pressure, and the elastic force of the pressure ring 4 and fits tightly with the bearing plate 1. At this time, the convex ring 202 can also effectively block the diversion holes 101, effectively complete the sealing of the independent unit, and effectively avoid the interference of the working environments of the sewage treatment bacteria in each independent unit. When discharging water, the sewage in the independent unit where the drain port 02 is located is discharged, and the one-way valve piece on the adjacent bearing plate 1 is in the open state to ensure the completion of the water discharge operation.
