Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1, a sewage filter with an automatic slag removal function comprises a filter box 1, wherein a water inlet 11 is arranged at the upper part of the filter box 1, a water outlet 12 is arranged at the lower part of the filter box 1, and a slag discharge port 13 is formed in the side wall of the middle part of the filter box 1; a filter screen plate 2 is vertically arranged in the filter box 1 in a sliding manner, and a water inlet 11 is positioned above the filter screen plate 2; a sealing cover 21 is arranged at the slag discharge port 13 in a sliding manner, and the upper end of the sealing cover 21 is fixedly connected with the filter screen 2; a horizontal mounting table 3 is fixedly arranged in the filter box 1, and the bottom of the filter screen plate 2 is elastically connected with the upper part of the horizontal annular mounting table through a return spring 31;
in a natural state, the slag discharge port 13 is positioned at one side below the filter screen plate 2; when the upper part of the filter screen plate 2 is blocked by slag, the filter screen plate 2 is pressed down by water pressure and the slag, so that the sealing cover 21 moves down along with the filter screen plate 2 to open the slag discharge port 13 until one end of the filter screen plate 2 is positioned at a slag discharge position, and the slag of the filter screen plate 2 is flushed out along with the accumulated sewage. Simple structure, it is with low costs, realized automatic slag removal's effect, avoid filtering 2 jams of otter board.
The inner wall of the filter box 1 is fixedly provided with a stop block 14, and when one end of the filter screen plate 2 is flush with the lower end of the slag discharge port 13, the lower end of the seal cover 21 is abutted against the stop block 14. The movement of the filter screen plate 2 and the sealing cover 21 is limited, and the filter screen plate 2 is prevented from moving to the lower part of the slag discharge port 13 to influence the slag removal effect.
The filter screen plate 2 is obliquely arranged in the filter box 1, and the lowest end of the filter screen plate 2 is close to the slag discharge port 13. The filter screen plate 2 is obliquely arranged, so that sewage can flow on the filter screen plate 2, and the flushing effect on slag is improved.
The water inlet 11 is positioned right above the highest end of the filter screen plate 2. The sewage that falls from the water inlet 11 can cover the whole of filter screen 2 to wash the slag completely, improve the slagging-off efficiency.
A collecting groove body 4 for collecting slag is arranged below the slag discharging port 13; the upper part of the collecting tank body 4 is provided with a slag inlet. The slag falling from the slag discharge port 13 is convenient to collect, and the environment is kept clean.
The collecting tank body 4 is fixedly arranged at the side part of the filter box 1, and a plurality of filter holes 41 communicated with the inside of the collecting tank body 4 and the inside of the filter box 1 are formed in the side wall, connected with the filter box 1, of the collecting tank body 4; the collection tank body 4 is positioned in the middle of the filter box 1. The sewage that falls into in the collection tank body 4 can enter into the rose box 1 from crossing the filtration pore 41, improves the sewage treatment effect, avoids extravagant.
The outer side wall of the filter screen plate 2 is provided with a sealing gasket which is contacted with the inner wall of the filter box 1, so that the sealing effect is improved.
The working principle is as follows: under a normal state, sewage with slag enters the filter box 1 from the water inlet 11, when the sewage passes through the filter screen plate 2, the slag is separated from the sewage, the sewage falls to the lower part through the filter screen plate 2 and flows out from the water outlet 12, the slag is accumulated on the filter screen plate 2, when the filter screen plate 2 is blocked due to too much slag accumulation on the filter screen plate 2, the filter screen plate 2 is pressed down under the action of the gravity of the slag and the water pressure, the sealing cover 21 is driven to move downwards, and the return spring 31 is compressed; until the seal cover 21 opens the slag discharge port 13, sewage on the filter screen plate 2 flows to the slag discharge port 13, meanwhile, slag is flushed to the slag discharge port 13, the sewage and the slag fall into the collection tank body 4 from the slag discharge port 13, the slag is collected in the collection tank body 4, and the sewage flows into the filter tank 1 through the filter holes 41 at the side part of the collection tank body 4 and then is discharged from the water outlet 12. After the slag on the filter screen 2 is washed clean, the filter screen 2 can work normally, under the action of the return spring 31, the filter screen 2 and the sealing cover 21 move upwards to the normal position, and the slag discharge port 13 is covered by the sealing cover 21. The automatic slag removal device has the advantages of realizing the automatic slag removal work of the filter screen plate 2, saving labor force and reducing the maintenance times, along with simple structure. In addition, collect cell body 4 and rose box 1 and pass through filtration pore 41 intercommunication, according to the principle of linker, through observing the liquid level in collecting cell body 4, can judge the liquid level in the rose box 1 to conveniently control the flow of water inlet 11 department.
Although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
