[0033] The sewage treatment tank 1 is powered by an external workshop power supply to drive the internal components to operate;

[0034] The sewage treatment tank 1 is also equipped with a device program, which can control the opening and closing of the motor 22;

[0035] The motor 22 and three groups of liquid level sensors are all connected to the equipment program signal.

[0036] Liquid level detection operation:

[0037] When the staff needs to use the sewage treatment tank 1, the staff first turns on the power of the workshop. At this time, the sewage treatment tank 1 starts, and the equipment program starts. When the sewage is injected, the equipment program detects the signal values ​​of the three groups of liquid level sensors and compares them with the set values. The equipment program sets the movement values ​​of the electric rolling door 21 to M1, M2, and M3. M1 is the minimum value and M3 is the maximum value. It can be adjusted according to specific needs. The speed of the motor 22 is V1, V2, and V3. V1 is the minimum value and V3 is the maximum value. It can be modified according to specific needs. During the use of the sewage treatment tank 1, it is set The equipment program continuously detects the signal values ​​of the three groups of liquid level sensors. When the equipment program detects the signal value of the first liquid level sensor 12, the equipment program determines that the sewage in the sewage treatment tank 1 is at a low liquid level, and the equipment program controls the motor 22 to start forward, and the speed is adjusted to V1. The movement value of the electric rolling door 21 is adjusted to M1. The motor 22 drives the door panel of the electric rolling door 21 to move slowly, so that the door panel of the electric rolling door 21 covers the top of the sewage treatment tank 1, which can prevent foreign objects from falling into the sewage treatment tank 1 and affecting the sewage treatment effect, and at the same time ensure the air circulation in the sewage treatment tank 1. To avoid turbid gas accumulation inside and affecting subsequent operations of staff, improve equipment service life and production safety, and not affect subsequent sewage injection, when the equipment program detects the signal value of the second liquid level sensor 13, the equipment program determines that the sewage in the sewage treatment tank 1 is at a medium liquid level, and the equipment program controls the speed of the motor 22 to be adjusted to V2, and the movement value of the electric rolling door 21 is adjusted to M2. The motor 22 drives the door panel of the electric rolling door 21 to move, so that the door panel of the electric rolling door 21 covers the top of the sewage treatment tank 1, which can prevent foreign matter from falling into the sewage treatment tank 1. Affecting the effect of sewage treatment, when the equipment program detects the signal value of the third liquid level sensor 14, the equipment program determines that the sewage in the sewage treatment tank 1 is at a high liquid level, and the equipment program controls the speed of the motor 22 to be adjusted to V2, and the movement value of the electric rolling door 21 is adjusted to M3, and the motor 22 drives the door panel of the electric rolling door 21 to move, so that the door panel of the electric rolling door 21 completely covers the top of the sewage treatment tank 1, preventing foreign matter from falling into the sewage treatment tank 1, and at the same time ensuring the air circulation in the sewage treatment tank 1, preventing turbid gas from accumulating inside and affecting the subsequent operation of the staff;

[0038] When the sewage treatment is completed, the equipment program controls the opening of the electric rolling door 21, and the equipment program controls the motor 22 to start in reverse, and the speed is adjusted to V3, so that the door panel of the electric rolling door 21 is quickly retracted, which is convenient for the staff to carry out the next operation and improve production efficiency;

[0039] By using the motor 22, the electric rolling door 21 and the three groups of liquid level sensors in coordination, the sewage level can be automatically detected after the sewage injection is completed, and different lengths of covering protection can be selected according to different liquid level heights. When treating low-level sewage, a shorter door panel is used for covering to avoid affecting the subsequent injection of medicine. When treating high-level sewage, it is completely covered to prevent foreign matter from falling into the sewage treatment tank 1 and affecting the sewage treatment effect. It can also prevent turbid gas from accumulating inside the sewage treatment tank 1 and causing safety hazards to the staff.

[0040] Door cleaning operation:

[0041] In the process of performing the above operation, the door panel of the electric rolling door 21 can be cleaned and protected. When the motor 22 is started, the motor 22 drives the electric rolling door 21 to rotate, and the second pulley 24 also rotates accordingly. At this time, the transmission belt 241 drives the first pulley 231 to rotate, and the first pulley 231 drives the cleaning brush cylinder 23 to rotate. The cleaning brush cylinder 23 wipes off the dust and sewage stains remaining on the surface of the electric rolling door 21 during its operation, thereby reducing the loss of the electric rolling door 21 during daily use. When the equipment program controls the rotation of the motor 22 When the speed is V1, the cleaning brush cylinder 23 rotates slowly to clean the surface of the door body of the electric rolling door 21 extending outward to prevent foreign matter from falling into the sewage treatment tank 1. When the speed of the motor 22 is adjusted to V2, the cleaning brush cylinder 23 increases the rotation speed to clean the surface of the door body of the electric rolling door 21 extending outward. When the speed of the motor 22 is adjusted to V3, the cleaning brush cylinder 23 quickly cleans the door body of the retracted electric rolling door 21 to prevent the sewage stains remaining on the door body of the electric rolling door 21 from rusting the door body, thereby increasing the service life of the electric rolling door 21.

[0042] By using two sets of pulleys, a transmission belt 241 and a cleaning brush cylinder, foreign objects and sewage stains that fall on the surface of the door body can be cleaned during the operation of the electric rolling door 21. The surface of the door body can be cleaned when the electric rolling door 21 is extended to prevent foreign objects from falling into the sewage treatment tank 1 during the movement of the door body. When the electric rolling door 21 is retracted, the sewage stains remaining on the surface of the door body can be cleaned to prevent rust from occurring inside the electric rolling door 21 and affecting subsequent normal use.

[0043] Ventilation Operation:

[0044] During the above operation, ventilation operation can be performed on the interior of the sewage treatment pool 1. When the motor 22 is started, the motor 22 drives the electric rolling door 21 to rotate, and the electric rolling door 21 drives the first bevel gear 32 and the third bevel gear 36 to rotate. The first bevel gear 32 is meshed with the second bevel gear 33, and the third bevel gear 36 is meshed with the fourth bevel gear 37. The second bevel gear 33 drives the first fan 34 to rotate, and the fourth bevel gear 37 drives the second fan 38 to rotate. The two sets of fans blow wind into the ventilation block 211 on the door body of the electric rolling door 21, so that the air in the sewage treatment pool 1 can circulate, and turbid gas can be prevented from accumulating inside the sewage treatment pool 1 and affecting the subsequent operations of the staff. , improve the safety factor during production, and avoid safety accidents caused by workers inhaling turbid gas. When the speed of the motor 22 is V1, the two sets of fans rotate slowly with the electric rolling door 21. At this time, the covering area of ​​the electric rolling door 21 is small, and it is only necessary to ensure the air circulation in the sewage treatment pool 1. When the speed of the motor 22 is V2, the two sets of fans rotate quickly, and the air is blown into the sewage treatment pool 1 through the ventilation block 211, thereby increasing the flow rate of the air inside the sewage treatment pool 1 and avoiding the accumulation of turbid gas. When the speed of the motor 22 is V3, the two sets of fans rotate at high speed, and the air is blown into the sewage treatment pool 1 through the ventilation block 211, thereby avoiding the workers from inhaling turbid air at the moment when the electric rolling door 21 is opened;

[0045] Through the coordinated use of four sets of bevel gears and two sets of fans, the interior of the sewage treatment pool 1 can be ventilated during the movement of the electric rolling door 21, preventing turbid air from accumulating inside the sewage treatment pool 1 and causing safety hazards. At the same time, it can prevent workers from inhaling turbid air at the moment the electric rolling door 21 is opened, thereby improving the safety factor during production.
