Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a convection type sewage treatment pool. Background Art

[0002] The pools used in sewage treatment are generally divided into sedimentation tanks, regulating tanks, biochemical tanks, and secondary sedimentation tanks. Among them, biochemical tanks usually use microorganisms to decompose organic matter in sewage. Most existing sewage treatment tanks do not have temperature regulation mechanisms. When the water temperature is higher than 40 degrees Celsius or lower than 15 degrees Celsius due to climate problems, the microbial decomposition rate will be greatly reduced, and the microbial reproduction rate will also be reduced, thereby reducing the efficiency of sewage treatment.

[0003] The announcement number authorized by China is CN216191585U, and it is named a patent for a convection sewage treatment tank. The device includes a water collecting tank, a stirring reaction tank is arranged on the right side of the water collecting tank, a controller is fixedly connected to the right side of the top of the water collecting tank, a first water pump is fixedly connected to the right side of the bottom of the water collecting tank, a pumping pipe is fixedly connected to the left end of the first water pump, a filter head is sleeved on the end of the pumping pipe away from the first water pump, a suspension plate is rotatably connected to the inner wall of the water collecting tank close to the controller, and a contact is movably connected to the inside of the controller close to the end of the controller. The controller can be triggered by the suspension plate after the sewage reaches a certain height, so the first water pump will be automatically started, and the sewage in the water collecting tank will be transferred into the stirring reaction tank through the first water pump, thereby achieving the effect of automatic drainage, which can effectively prevent the problem of overflow after the water is full, saving a lot of time and saving the physical strength of the staff.

[0004] Although the above device can effectively prevent the problem of overflow after the water is full, there are still some problems when using the device:

[0005] 1. The device does not have a heat preservation and temperature regulation structure, and it is set up outdoors. When the temperature in the environment is low or high, the water temperature will be too high or too low, and the speed and reproduction rate of microorganisms in the sewage to decompose organic matter will be greatly reduced, or even stop decomposing organic matter.

[0006] 2. The motor of the device is located at the bottom of the pool. When the motor needs to be maintained, the water needs to be drained and the motor protection structure needs to be disassembled, so its maintenance is more troublesome.

[0007] In view of the above situation, technological innovation is carried out based on the existing sewage treatment pool. Utility Model Content

[0008] The purpose of the utility model is to provide a convection sewage treatment tank to solve the problems raised in the above background technology.

[0014] Furthermore, one side of the bevel gear one is meshedly connected with the bevel gear two, and a rotating rod is fixed on the inner side of the bevel gear two.

[0015] Furthermore, a driving assembly is fixed to the top of the mounting frame, and the driving assembly includes a reducer and a motor, and the motor is fixed to the top of the reducer.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: the device is provided with a heat preservation structure and a temperature regulating mechanism, which can adjust the temperature inside the device within a certain range, so that the water temperature of the sewage is maintained in an appropriate range, which is beneficial to improving the treatment efficiency; at the same time, the device is provided with a driving mechanism exposed to the water surface, and the driving mechanism is not easily damaged by moisture and is easy to maintain.

[0017] 1.

The temperature sensor can detect the temperature of sewage and transmit it to the display screen through the wire to display the water temperature. When the water When the temperature is high, the staff can open the electric shutters and close the electric awning. At this time, the air flow can pass through the electric shutters, and the sunlight will be blocked by the electric awning. Therefore, the interior of the device is relatively ventilated and cool, which can effectively reduce the water temperature. When the water temperature is low, the staff can close the electric shutters and open the electric awning. At this time, the interior of the device is relatively closed, which can effectively maintain the water temperature.

The output shaft of the motor 2002 is connected to the input end of the reducer 2001, and the rotating rod 19 is connected to the output end of the reducer 2001. When the motor 2002 is turned on, the motor 2 002 drives the rotating rod 19 to rotate through the reducer 2001, thereby rotating the bevel gear 2 18, and the bevel gear 2 18 can drive the bevel gear 1 17 to rotate, thereby rotating the rotating shaft 15 and the propeller 16, and the propeller 16 can generate convection water flow in the convection tank body 5, thereby improving the sewage treatment efficiency. Since the height of the mounting frame 14 is relatively high, when the convection tank body 5 is filled with water, the motor 2002 and the reducer 2001 are both located above the water surface, reducing the possibility of water entering the motor 2002, and there is no need to drain water when maintaining the motor 2002 and the reducer 2001. This is the working principle of the convection sewage treatment tank.
