Description

Technical Field

[0001] The present application relates to the technical field of sewage pretreatment tanks, and in particular to a pretreatment tank with a negative pressure prevention device. Background Art

[0002] Sewage pretreatment tanks are equipment used to perform preliminary treatment on sewage. This treatment usually includes removing impurities such as large particles, sediments and grease to reduce the burden of subsequent treatment steps. Pretreatment helps maintain the normal operation of downstream equipment and improve the efficiency of the entire sewage treatment system.

[0044] A control valve 8 is fixedly connected to one side of the upper part of the tank body 1, and an air pipe 7 is fixedly connected to the inner wall of the control valve 8;

[0045] Specifically, the liquid is introduced into the tank body 1 through the feed pipe 4, and then the flow of the liquid drives the fan blades 10 to move, and the connecting shaft 11 drives the rotating shaft 15 to rotate, so that the stirring rod 19 on the rotating shaft 15 stirs the liquid entering the tank body 1, and after the liquid filling is completed, the gas in the tank body 1 is extracted by the air pipe 7 to form a negative pressure state. During this process, the flow of the gas can also drive the fan blades 10 to rotate, and provide power for the rotation of the rotating shaft 15, so that the potential energy of the liquid entry process and the power of the gas extraction process can be converted, thereby providing power for the liquid processing process.

[0047] The other end of the elastic curved sheet 20 is fixedly connected to an auxiliary ring plate 21, and the outer wall of the auxiliary ring plate 21 is fixedly mounted on the inner wall of the tank body 1;

[0048] Specifically, through the connectivity between the rotating shaft 15, the pin 25 and the connecting shaft 11, during the continuous rotation of the rotating shaft 15, the pin 25 is driven to drive the elastic curved piece 20 with the cooperation of the positioning frame 22, so that it is continuously rotated and squeezed, and with the cooperation of the ratchet ring 24, its elastic potential energy is continuously stored, and when the sealing plug 5 is inserted into the feed pipe 4 and the inclined cone ring 9, it contacts the fan blade 10 and causes extrusion, which drives the pin 25 in the ratchet ring 24 downward and squeezes the spring telescopic rod 26. After the ratchet ring 24 loses the limit of the pin 25, the elastic curved piece 20 releases the accumulated elastic potential energy and drives the rotating shaft 15 to rotate, thereby accumulating the generated dynamic potential energy, and after packaging, the elastic potential energy is released to process the liquid again, thereby improving the effect of its stirring treatment and making the liquid and the medicine evenly mixed.

[0052] Specifically, after the liquid is introduced, it passes through the positioning cone ring plate 14, and the liquid is filtered in the filter screen plate 13 and enters the tank body 1. Then, during the rotation of the rotating shaft 15, the brush rack plate 17 above the rotating shaft 15 cleans the filter screen plate 13, and at the same time, the stirring rod 19 in the middle of the rotating shaft 15 stirs the liquid in the tank body 1, thereby being able to perform pre-treatment operations of filtering and stirring the liquid, thereby improving the effect of its liquid treatment.

[0053] The working principle of the present application is as follows: the staff introduces the liquid into the tank body 1 through the feed pipe 4, and the flow of the liquid drives the fan blades 10 to move, and the connecting shaft 11 drives the rotating shaft 15 to rotate, so that the stirring rod 19 on the rotating shaft 15 stirs the liquid entering the tank body 1, and after the liquid filling is completed, the gas in the tank body 1 is extracted by the air pipe 7 to form a negative pressure state. During this process, the flow of the gas can also drive the fan blades 10 to rotate, and provide power for the rotation of the rotating shaft 15. Due to the connectivity between the rotating shaft 15, the pin shaft 25 and the connecting shaft 11, during the continuous rotation of the rotating shaft 15, the pin shaft 25 drives the elastic curved sheet 20 with the cooperation of the positioning frame 22, so that it is continuously rotated and squeezed, and the elastic curved sheet 20 is continuously rotated and squeezed with the cooperation of the ratchet ring 24.

Then, during the rotation of the rotating shaft 15, the brush frame plate 17 above the rotating shaft 15 cleans the filter screen plate 13, and at the same time, the stirring rod 19 in the middle of the rotating shaft 15 stirs the liquid in the tank body 1.
