Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easy to understand, the following description and the accompanying drawings further illustrate the preferred embodiments of the invention.

Examples

Referring to fig. 1 to 5, the present invention provides a water supply and drainage device for a sewage treatment tank, which includes a drainage pipe 3 and a drainage pump, an intermittent rotary fan 1 and a plug 2 are installed at a position where the drainage pipe 3 is not connected to the drainage pump, the plug 2 and the drainage pipe 3 are movably engaged, the intermittent rotary fan 1 is installed at the center inside the plug 2, the intermittent rotary fan 1 is composed of a central rotary shaft 11, a rotary shaft main body 12, a first blade 13, a bottom support 14, a circular clamping seat 15, a three-dimensional rotary shaft 16, and a second blade 17, the first blade 13 and the second blade 17 are respectively installed at two sides of the outer side surface of the rotary shaft main body 12, the second blade 17 and the first blade 13 are both provided with two or more, the first blade 13, the second blade 17 and the rotary shaft main body 12 are horizontally and wirelessly welded by a welding machine, the rotary shaft main body 12 is vertically fixed on the top end surface of the circular clamping, the circular clamping seat 15 and the bottom support 14 are movably clamped, the bottom support 14 and the circular clamping seat 15 are movably matched, and the edge of the bottom support 14 is horizontally welded with the inner wall of the plug 2.

The first blade 13 and the second blade 17 are both arc-shaped sheet structures, and when the water in the sewage treatment tank is pumped by the drainage pump, the flowing water flow can impact the first blade 13 and the second blade 17, so that the direction of the water flow is changed.

The included angle between the first blade 13 and the outer tangent of the rotating shaft main body 12 is smaller than the included angle between the second blade 17 and the outer tangent of the rotating shaft main body 12, water flow impacts the first blade 13 and the second blade 17 to enable the rotating shaft main body 12 to rotate in a variable speed mode, water flow entering the water discharge pipe 3 is further enabled to flow intermittently, and blockage in the water discharge pipe 3 is avoided.

The quantity of first blade 13 is greater than the quantity of second blade 17, and the quantity is different, and is the structure of symmetric distribution, guarantees intermittent type nature and lets the rivers circulation, also can make its clearance circulation to two sets of different sediments, guarantees that the sediment does not take place to block up.

The incomplete circular plate of bottom sprag 14 slope, sediment is difficult to pile up under the inclined state to bottom sprag 14, and incomplete circular plate also makes things convenient for the rivers circulation.

Be equipped with directly over the end shoring 14 and strip structure 10, strip structure 10 by scraping strip 5, link up mouth 6, line pole 7, apron 8 is irregular shape, it has one to link up mouth 6 to open directly over the apron 8 is located pivot main part 12, link up mouth 6 and pivot main part 12 adopt clearance fit, be equipped with two line poles 7 directly over the end shoring 14, it is fixed with 2 tops of end cap adoption levels to lap 8, be equipped with more than two scraping strip 5 on the line pole 7, because the extraction be the water in the sewage treatment pond, can extract the precipitate after handling unavoidably, have the precipitate to remain on it through first blade 13 and second blade 17.

The scraping strip 5 is a spiral elastic sheet, the tail end of the scraping strip is not fixed on the bottom support 14, and the scraping strip can move up and down to clean the first blade 13 or the second blade 17 without residue.

When the drainage pump operates and sewage in the sewage treatment tank is sucked through the drainage pipe 3, when water flows through the intermittent rotary fan 1, the water flows firstly contact with the first blade 13 or the second blade 17, the intermittent rotary fan 1 is gradually rotated by the impact force of the water flows, the water flows through the first blade 13 or the second blade 17 are folded to impact the inner wall of the plug 2, the excessively turbid and thick sewage is scattered and smoothly flows downwards, the splashed sewage falls on the bottom support 14 in the process, the bottom support 14 of the inclined circular plate is an incomplete closed bottom support 14, the sewage falling on the bottom support smoothly flows downwards, the bottom support 14 cannot be precipitated and accumulated, and the blocking problem is caused;

when the central rotating shaft 11 rotates to the other side, namely the position of the second blade 17 or the first blade 13, the impact force of the received water flow is unchanged, and because of the angle difference between the first blade 13 or the second blade 17 and the rotating shaft main body 12, the impact force is changed, so that the intermittent rotating fan 1 is changed, the flow of the sewage led into the drain pipe 3 is changed, thereby realizing intermittent flowing water and ensuring that the drain pipe 3 is not blocked;

when first blade 13 or second blade 17 rotate to apron 8 under, the spiral helicine elastic sheet's strip 5 of scraping can be activity from top to bottom and scrape first blade 13 or second blade 17 on because sewage flows and produce the incrustation scale, avoid first blade 13 or second blade 17 incrustation scale to pile up too much and change intermittent type and change 1 rotational speed of fan, can't realize intermittent type flowing water.

The invention solves the problem that when the drainage pump is adopted to drain the sewage in the sewage treatment tank, the drainage pipe is often blocked due to the suction of sediments in the water, such as plant fibers and the like, so that the water can not be continuously absorbed for drainage, and the drainage efficiency is reduced.
