[0006] The utility model relates to a variable frequency speed regulation sewage treatment mixer; moving device, fixing device and stirring device are included, fixing device installs on moving device, stirring device installs on moving device; drive stirring device to move in sewage pool through moving device, quickly stir the sewage in different areas, assist in fixing the position of stirring device on moving device through fixing device, reduce the influence of the vibration of stirring device on the whole equipment during operation, improve the stability of the device, quickly mix and stir the sewage and sewage treatment chemicals through the stirring device, and improve the practicality of the device.

[0007] Preferably, the mobile device includes a sewage tank, a support frame, a dual-output reducer, a motor, lead screws, and a transverse platform. The support frame is mounted on the upper surface of the sewage tank, and the dual-output reducer is mounted on the left end of the support frame. A motor is mounted on the dual-output reducer. A slotted hole is provided on the upper surface of the support frame, and a set of lead screws is horizontally mounted in the slotted hole, one at the front and one at the back. The two output ends of the dual-output reducer are connected to the two sets of lead screws respectively. The transverse platform is located in the slotted hole of the support frame and is connected to the two sets of lead screws via two sets of nuts. Turning on the motor transmits power to the two sets of lead screws through the dual-output reducer, causing them to rotate. This, in turn, works with the two sets of nuts on the transverse platform to move the platform left and right, thereby driving the mixing device to mix and stir the sewage in different areas, improving the practicality of the device.

A set of limiting grooves is provided on the front and rear end faces of the strip hole on the support frame, and a set of support plates is provided on the front and rear end faces of the transverse platform. The two sets of support plates are inserted into the two sets of limiting grooves in the strip hole on the support frame. Multiple sets of support rollers are evenly arranged on the lower end face of the limiting grooves, and a sliding limiting groove is provided on the lower end face of the support plate. The two sets of support plates and multiple sets of support rollers work together to provide auxiliary support for the transverse platform, improving the stability of the device, reducing the pressure on the lead screw during the operation of the mixing device, and preventing the lead screw from deforming under pressure. The sliding limiting groove on the lower end face of the support plate, in conjunction with the support rollers, limits the movement of the transverse platform, reducing its own swaying amplitude during movement, thus improving the practicality and stability of the device.

A cleaning plate is installed at the bottom of the mixing blades, and the cleaning plate is provided with multiple sets of through holes. Multiple sets of brushes are evenly installed on the lower surface of the cleaning plate. When the variable frequency motor is turned on, the power is transmitted to the mixing blades, which drive the mixing blades to rotate. The rotating mixing blades mix and stir the sewage. The brushes at the bottom of the cleaning plate clean the sediment at the bottom of the sewage tank, so that the sewage is evenly mixed. The through holes on the cleaning plate facilitate the rapid passage of the bottom sediment through the cleaning plate and its mixing with the sewage, which improves the practicality of the device.

[0011] Preferably, the device also includes a storage tank, a water pump, a spray plate, and nozzles. The spray plate is connected to the lower end face of the through hole via a sleeve. The storage tank and the water pump are installed on the upper end face of the spray plate. Multiple sets of nozzles are installed on the lower end face of the spray plate. The input end of the water pump is connected to the storage tank, and the output end of the water pump is connected to the nozzles at the bottom of the spray plate. When the water pump is turned on, the wastewater treatment agent in the storage tank is extracted and transferred to the multiple sets of nozzles for spraying, thereby making the wastewater treatment agent and wastewater uniformly mixed, improving the practicality of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the moving device drives the stirring device to move in the sewage tank, and the sewage in different areas is quickly stirred. The fixed device helps to fix the position of the stirring device on the moving device, reducing the impact of the stirring device's own vibration on the overall equipment during operation and improving the stability of the device.
