Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a submersible mixing device. Background Technology

[0002] Submersible mixing devices, also known as submersible propellers, are devices capable of stirring, mixing, propulsion, and conveying in deep water. Their main working principle involves a motor driving an impeller to rotate, converting the kinetic energy of the water into mechanical energy. This causes the impeller to generate strong circulation and tangential flow in the surrounding water, thereby achieving mixing, stirring, and propulsion.

[0003] The prior art disclosure number CN217248131U discloses a submersible sewage treatment mixing device in the field of sewage treatment technology, including a sewage tank and a submersible mixer. The submersible mixer is installed in the bottom of one side of the sewage tank. It also includes a bottom plate, a top plate, a mounting assembly, and a rotating mechanism. The bottom plate is fixedly installed on one side of the sewage tank, and the top plate is fixedly installed on the top of the sewage tank near the bottom plate. The mounting assembly is slidably mounted on the bottom plate, and the submersible mixer is fixedly installed on the mounting assembly. The rotating mechanism includes an elastic rotating shaft assembly and a drive assembly. This utility model can realize the reciprocating rotation of the submersible mixer in the horizontal direction, thereby making the flow direction of the submersible mixer constantly change. This allows the submersible mixer to change the mixing direction of the fluid in the sewage tank, resulting in better mixing effect and greater flexibility.

[0004] With the above configuration, the existing mixing device, through the cooperation of the drive assembly and the flexible rotating shaft assembly, enables the submersible mixer to reciprocate horizontally, thereby continuously changing the flow direction of the submersible mixer. This allows for changes in the mixing direction of the fluid in the sewage tank, resulting in better mixing effect and greater flexibility. However, the existing mixing device has the following drawbacks during operation:

[0005] After prolonged use, the surface of the submersible mixer in the existing mixing device will accumulate a lot of contaminants, thus requiring regular cleaning and maintenance. Since the submersible mixer cannot move up and down, wastewater must be discharged before cleaning and maintenance can be carried out, which is a very troublesome process. Moreover, wastewater discharge usually takes a long time, which is not conducive to cleaning and maintenance of the submersible mixer and greatly reduces its service life. Utility Model Content

[0006] The present invention aims to provide a submersible mixing device, which is mainly used to solve the technical problem that the existing technology cannot effectively clean and maintain the submersible mixer, thus greatly reducing the service life of the submersible mixer.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A submersible mixing device includes a sewage tank, a top plate, and a submersible mixer. The top plate is fixedly connected to the upper surface of the sewage tank. A rotating rod is rotatably connected to the lower surface of the top plate, and the bottom surface of the rotating rod is rotatably connected to the bottom surface of the sewage tank. Symmetrical guide rods are fixedly connected to the outer wall of the rotating rod. A drive motor for driving the rotating rod to rotate is installed on the upper surface of the top plate. A sliding sleeve is slidably connected to the outer wall of the rotating rod and the guide rod. An L-shaped plate is fixedly connected to one side of the sliding sleeve. A T-shaped groove is opened on one side of the L-shaped plate. A T-shaped plate is slidably connected to the inner wall of the T-shaped groove. The T-shaped plate is fixedly connected to the submersible mixer. A drive mechanism is fixedly connected to the upper surface of the sewage tank. A movable cavity is opened inside the L-shaped plate, and a limit component is installed inside the movable cavity.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When the mixing device is needed, first place the submersible mixer on the L-shaped plate, so that the T-shaped plate is inserted into the T-shaped groove. The T-shaped plate is limited by the limiting component. Then, connect the steel wire rope on the drive mechanism to the submersible mixer. Then, start the winding motor to place the submersible mixer into the sewage. Then, it can mix the sewage in the sewage tank. When the submersible mixer needs to be cleaned and maintained, the winding motor is used to wind up the steel wire rope to drive the submersible mixer out of the sewage tank, and then it can be cleaned and maintained.

[0011] 2. Beneficial effects:

[0012] Existing technology enables submersible mixers to reciprocate horizontally by using a drive assembly and a flexible rotating shaft assembly. This allows the flow direction of the submersible mixer to continuously change, thus altering the mixing direction of the fluid in the sewage tank. This improves the mixing effect and flexibility of the submersible mixer. However, after prolonged use, the surface of the submersible mixer accumulates many contaminants, requiring regular cleaning and maintenance. Since the submersible mixer cannot move vertically, cleaning and maintenance can only be performed after the sewage has been drained. The process is quite cumbersome, and wastewater discharge usually takes a long time, which is not conducive to cleaning and maintaining the submersible mixer, greatly reducing its service life. This solution addresses this by setting up a rotating rod, guide rod, sliding sleeve, drive mechanism, and limit mechanism. The drive mechanism moves the submersible mixer up and down via a steel wire rope. The submersible mixer drives the sliding sleeve to slide on the guide rod and rotating rod, thus guiding the submersible mixer. When maintenance and cleaning of the submersible mixer are required, the drive mechanism moves the submersible mixer up and down, making maintenance more convenient and faster. At the same time, the limit mechanism can also solve the technical problems of disassembling and replacing the submersible mixer.

[0013] Preferably, the drive mechanism includes support rods fixedly connected to the upper surface of the sewage tank. A winding roller is rotatably connected between the support rods. A winding motor is mounted on one side of each support rod, and the output end of the winding motor passes through the support rod and is fixedly connected to the winding roller. A steel wire rope is wound around the outer wall of the winding roller, and one end of the steel wire rope is fixedly connected to the top surface of the submersible mixer. By setting up the drive mechanism, the submersible mixer can be raised and lowered via the steel wire rope, facilitating maintenance and cleaning of the submersible mixer.

[0014] Preferably, the limiting component includes a spring shaft rotatably connected to the inner wall of the movable cavity. One end of the spring shaft is fixedly connected to a crossbar, which is rotatably connected to the inner wall of the movable cavity. An arc-shaped groove is formed on one side of the T-shaped plate, and the crossbar abuts against the arc-shaped groove. A rotating rod is fixedly connected to the side of the crossbar away from the spring shaft, and the rotating rod passes through and is rotatably connected to the L-shaped plate. By setting the limiting component, the submersible mixer can be disassembled for easy replacement.

[0015] Preferably, a connecting block is fixedly connected to the end of the wire rope away from the take-up roller, and an internally threaded cylinder is rotatably connected to the bottom surface of the connecting block. A threaded rod is fixedly connected to the upper surface of the submersible mixer, and the internally threaded cylinder is threadedly connected to the threaded rod. By setting the threaded rod and the internally threaded sleeve, the wire rope can be easily disassembled from the submersible mixer. At the same time, the connecting block prevents the wire rope from generating torque and avoids the wire rope from driving the internally threaded cylinder to rotate.

[0016] Preferably, the inner wall of the sliding sleeve has symmetrical movable grooves, and multiple rollers are rotatably connected to the inner wall of the movable grooves. The rollers contact the outer wall of the guide rod. By setting the rollers, the sliding sleeve can be easily slid and friction can be reduced.

[0017] Preferably, a rotating block is fixed to the end of the rotating rod away from the crossbar. This facilitates the rotation of the rotating rod.

[0018] Preferably, the outer wall of the internally threaded cylinder has anti-slip textures to increase friction. Attached Figure Description
