Description

Technical Field

[0001] This utility model relates to the field of agitator technology, specifically a novel vertical circulating agitator. Background Technology

[0002] The vertical circulating agitator is a mixing device widely used in deep-tank wastewater treatment where mixing is required. For example, it can be installed in a dosing tank to mix the chemicals evenly through agitation. It innovatively transforms the traditional horizontal structure into a vertical circulating structure.

[0003] In the prior art, Chinese patent application number CN201520555745.4 discloses a novel vertical circulating agitator, which includes an impeller, a guide shroud, a submersible motor, and a mounting sleeve. A float is fitted onto the upper end of the mounting sleeve, and a float panel is provided at the top. The float panel is fixed to the float. An intermediate support is provided at the lower end of the mounting sleeve, and a lower support is provided below the intermediate support. A submersible motor is provided at the bottom of the lower support, and a guide shroud is provided below the submersible motor. A mechanical seal is provided on the output shaft, and an impeller is provided at the lower end of the mechanical seal. The impeller is fixed to the output shaft of the submersible motor with screws. The lower end of the guide shroud is the outlet, and the upper end is the inlet. The angle between the support and the lower end face is 35 to 42 degrees. During agitation, sewage enters obliquely from the inlet of the guide shroud, driving a large area of ​​sewage in the tank to be drawn in. It is discharged from the lower end in a rotating vortex, and spreads outward and upward when it hits the bottom of the treatment tank. The cycle of circulation and agitation is repeated, which greatly improves the agitation effect of the treatment tank.

[0004] Based on the above information, it can be seen that in the prior art, the stirring blades are generally rotated by a motor to achieve the purpose of stirring. However, in actual use, the position of the stirring blades is fixed (i.e., there is no relative displacement), and the overall stirring range is small. Utility Model Content

[0005] The purpose of this invention is to provide a novel vertical circulating agitator to solve the problem of small stirring range mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel vertical circulating agitator, comprising a mounting plate fixedly installed in a sewage treatment dosing tank, a drive shaft rotatably mounted below the mounting plate, and agitator blades fixedly mounted at the bottom end of the drive shaft, a fixing frame fixedly mounted on the upper surface of the mounting plate, a drive motor fixedly mounted on the upper surface of the fixing frame, and a reduction gearbox fixedly mounted below the fixing frame, the drive motor transmitting power to the drive shaft through the reduction gearbox; the drive shaft is divided into three parts: an upper shaft body, a lower shaft body, and a universal coupling, and a reciprocating mechanism for driving the lower shaft body to swing is provided on the lower surface of the mounting plate.

[0007] Preferably, the upper end of the upper shaft is connected to the output end of the gearbox, and the upper shaft and the lower shaft are rotatably connected by a universal coupling.

[0008] Preferably, the reciprocating mechanism includes a reciprocating lead screw rotatably mounted below the mounting plate, and a movable slider is threaded through the outside of the reciprocating lead screw.

[0009] Preferably, a connecting rod is rotatably mounted at the lower end of the movable slider, and the bottom end of the connecting rod is rotatably mounted to the connecting sleeve, and the connecting sleeve is slidably mounted outside the lower shaft.

[0010] Preferably, a driven bevel gear for driving the reciprocating screw to rotate is coaxially fixedly installed at the top end of the screw, and the driven bevel gear is meshed with a driving bevel gear fixedly installed outside the upper shaft.

[0011] Preferably, an air pump is fixedly installed on the lower surface of the mounting plate, and an aeration pipe is fixedly installed at the air outlet of the air pump.

[0012] Preferably, two flow guide baffles are fixedly installed at the middle position of the lower surface of the air pump, and the cross-section of each flow guide baffle is in the shape of an "eight".

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel vertical circulating agitator adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The power of the drive motor is transmitted to the transmission shaft through the gearbox, and then the transmission shaft drives the stirring blades to rotate, so as to stir the medicine in the dosing tank. Since the transmission shaft is divided into two parts, the upper shaft and the lower shaft are connected by a universal coupling, the lower shaft can swing left and right to expand the overall stirring range.

[0015] Furthermore, during the rotation of the upper shaft, the driving bevel gear fixedly installed therewith rotates. At this time, the driven bevel gear, which is meshed with the driving bevel gear, drives the reciprocating screw to rotate. During the rotation of the reciprocating screw, the movable slider installed on its external through thread moves back and forth. Thus, the connecting rod at the lower end of the movable slider drives the lower shaft to swing left and right through the connecting sleeve.

[0016] 2. When using the device, turn on the air pump. At this time, the air pump will discharge air through the aeration pipe and add oxygen to the dosing tank to improve the activity of the agent. When the air flows, it hits the guide baffle and improves the stirring effect of the agent through the airflow. Attached Figure Description

The drive motor 5 transmits power to the drive shaft 2 through the reduction gearbox 6. The drive shaft 2 is divided into three parts: an upper shaft body 201, a lower shaft body 202, and a universal coupling 203. A reciprocating mechanism for driving the lower shaft body 202 to swing is provided on the lower surface of the mounting plate 1. The upper end of the upper shaft 201 is connected to the output end of the gearbox 6, and the upper shaft 201 and the lower shaft 202 are rotatably connected by a universal coupling 203. The reciprocating mechanism includes a reciprocating screw 10 rotatably mounted below the mounting plate 1, and a movable slider 9 is threaded through the outside of the reciprocating screw 10. A connecting rod 8 is rotatably mounted at the lower end of the movable slider 9, and the bottom end of the connecting rod 8 is rotatably mounted with a connecting sleeve 7.

A driven bevel gear 11 for driving its rotation is coaxially fixedly mounted at the top end of the reciprocating screw 10, and the driven bevel gear 11 is meshed with a driving bevel gear 12 fixedly mounted outside the upper shaft 201.

[0026] When using the device, firstly, the mounting plate 1 is fixedly installed in the dosing tank of the sewage treatment tank, and the stirring blade 3 is located inside the dosing tank. Then, the drive motor 5 is turned on. The power of the drive motor 5 is reduced by the reduction gearbox 6 and transmitted to the transmission shaft 2. Finally, the transmission shaft 2 drives the stirring blade 3 at its bottom to rotate, so as to achieve the purpose of stirring the agent inside the stirring blade 3. During the rotation of the transmission shaft 2, the upper shaft 201 drives the active bevel gear 12 fixedly installed thereto to rotate. During the rotation of the active bevel gear 12, it drives the driven bevel gear 11 that is meshed with it to rotate. The driven bevel gear 11 drives the reciprocating screw 10 to rotate. During the rotation of the reciprocating screw 10, the movable slider 9 installed with the thread through its exterior moves back and forth. The movable slider 9 drives the connecting sleeve 7 to move through the connecting rod 8 at its lower end. The connecting sleeve 7 drives the lower shaft 202 to swing left and right (the connecting sleeve 7 can slide relative to the lower shaft 202), thereby expanding the stirring range.

[0027] Example 2: Please refer to Figure 6 In order to achieve the purpose of injecting oxygen to improve the activity of the agent, this embodiment provides the following technical solution, which specifically discloses: an air pump 13 is fixedly installed on the lower surface of the mounting plate 1, and an aeration pipe 14 is fixedly installed at the air outlet of the air pump 13.
