If you rashly enter the fermentation tank to clean it, there is a risk of suffocation and poisoning. In addition, the aeration pipes in the existing fermentation tank are easily blocked by silt residue, resulting in insufficient aeration and affecting the reproduction of microorganisms. Therefore, a fermentation device for sewage treatment is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 4A fermentation device for sewage treatment includes a fermentation tank body 1, an air inlet pipe 110 is arranged on the top of the fermentation tank body 1, an aeration pipe 120 is arranged inside the fermentation tank body 1, and a pipeline cleaning mechanism 2 is arranged on the side wall of the fermentation tank body 1;

[0022] The aeration pipe 120 is divided into an aeration section 121, a propulsion section 122 and a connection section 123. The aeration section 121 is a circular ring structure. The pipeline cleaning mechanism 2 includes a motor 201, a waterproof frame 203 and a cleaning wheel 202. The motor 201 is installed in the waterproof frame 203 and is connected to the cleaning wheel 202 through a synchronous belt and a synchronous wheel transmission. The cleaning wheel 202 is in contact with the lower end surface of the aeration pipe 120.

[0023] When the device is in use, during the sewage fermentation process, air is introduced into the aeration pipe 120 through the air inlet 111 through the external air compressor, so that the aeration pipe 120 is aerated by spraying through the horizontal spray holes 125 and the aeration holes 124, thereby improving the sewage treatment effect. If the aeration holes 124 are blocked, the motor 201 is started to drive the cleaning roller to brush the aeration holes 124 of the aeration pipe 120, thereby improving the dredging effect of the aeration pipe 120. When the fermentation tank needs to be cleaned, clean water is introduced through the water inlet 112, and high-pressure air is introduced through the air inlet 111, so that the water flow is sprayed at high speed from the aeration holes 124 onto the inner wall of the fermentation tank to flush it, and the water flow sprayed from the horizontal spray holes 125 will drive the aeration pipe 120 to rotate, thereby evenly flushing the inner wall of the fermentation tank body 1.

[0024] Furthermore, a joint 130 is provided at the end of the air inlet pipe 110 , and the connecting section 123 is inserted into the joint 130 and rotatably connected thereto.

[0025] The air inlet pipe 110 can rotate around the center of the joint 130, so that the aeration pipe 120 can rotate. The pipeline cleaning mechanism 2 can fully clean the aeration pipe 120. When the aeration pipe 120 is connected to the water pipe, the aeration pipe 120 can rotate to flush the inner wall of the equipment.

[0026] Furthermore, a locking bolt 131 is threadedly connected to a side end surface of the joint 130 .

[0027] By tightening the locking bolt 131 to squeeze the inner side wall of the aeration tube 120 , the aeration tube 120 can be locked, thereby reducing kinetic energy loss and increasing the injection pressure.

[0028] Furthermore, the propulsion section 122 is a “V”-shaped pipe, and a side wall of the propulsion section 122 is provided with a horizontal spray hole 125 .

[0029] When the airflow is ejected from the horizontal spray hole 125 , a certain reaction force is generated, thereby pushing the aeration pipe 120 to rotate around the connecting section 123 , without the need for external power, thereby improving the environmental protection performance of the equipment.

[0030] Furthermore, bristles 204 are provided on the surface of the cleaning wheel 202 , and aeration holes 124 are provided at the bottom of the aeration tube 120 .

[0031] The cleaning wheel 202 is driven to rotate by the motor 201 , so that the bristles 204 brush the aeration holes 124 to sweep out foreign objects blocked in the aeration holes 124 .

[0032] Furthermore, the angle between the aeration hole 124 and the inner wall of the fermentation tank body 1 is thirty degrees.

[0033] When the aeration pipe 120 is connected to the water pipe, water flows along the aeration holes 124 toward the inner wall of the fermentation tank body 1, thereby flushing the inner wall of the fermentation tank body 1, greatly improving the convenience of cleaning the fermentation tank.

[0034] Furthermore, a water inlet 112 and an air inlet 111 are provided at the end of the air inlet pipe 110 away from the joint 130 , and a one-way valve 113 is provided on both the air inlet 111 and the water inlet 112 .

[0035] When the air inlet 111 is connected to the air compressor, the aeration pipe 120 sprays high-pressure air for aeration. When the water inlet 112 is connected to the external water pipe, the aeration pipe 120 sprays high-pressure water to flush the inner wall of the fermentation tank. High-pressure gas and water can be introduced at the same time to increase the spray pressure.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
