Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency stirring device for sewage treatment. Background Art

[0002] Sewage refers to water that has been polluted to a certain extent and has lost its original use function. It contains a lot of organic matter. Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] There are many types of sewage. The sewage discharged by many enterprises contains a large amount of difficult-to-degrade substances that cannot be effectively removed by a single water treatment equipment. Therefore, in many cases, sewage treatment chemicals must be reasonably added according to the particularity of sewage quality so that the treated sewage meets the national emission standards. When using sewage treatment chemicals to treat sewage, the sewage needs to be stirred to accelerate the mixing of sewage and sewage treatment chemicals.

[0004] However, in the prior art, the stirring blades of the sewage stirring device are usually fixed, resulting in a relatively single flow field pattern. It is impossible to form a uniform flow and shear distribution in the entire reaction tank, the mixing effect is limited, and the problem of mixing dead corners is prone to occur. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency stirring device for sewage treatment, which has the advantage of adjustable stirring blades and solves the problems of being unable to form uniform flow and shear distribution in the entire reaction tank, having limited mixing effect, and easily appearing mixing dead corners.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency stirring device for sewage treatment, comprising an adjusting mechanism, the adjusting mechanism comprising a fixed seat, a transmission rod is rotatably installed inside the fixed seat, a mounting sleeve is fixedly installed on the top of the transmission rod, a plurality of first connecting rods are movably installed on the outer wall of the mounting sleeve, a second connecting rod is movably installed on one end of the first connecting rod, a connecting arm is fixedly installed on one side of the second connecting rod, a first ball head is fixedly installed on one end of the connecting arm, and a stirring structure is fixedly installed on one end of the second connecting rod.

[0007] As a preferred embodiment of the utility model of a high-efficiency stirring device for sewage treatment, the adjustment mechanism also includes a second hydraulic rod, one end of the second hydraulic rod is movably mounted on one side of the second connecting rod, and the other end of the second hydraulic rod is movably mounted on one side of the first connecting rod.

[0008] As a preferred embodiment of the utility model of a high-efficiency stirring device for sewage treatment, a main body mechanism is fixedly installed on the bottom of the fixed seat, and the main body mechanism includes a stirring tank.

[0009] As a preferred embodiment of the utility model of a high-efficiency stirring device for sewage treatment, a reducer is fixedly installed at the bottom of the stirring tank, a motor is fixedly installed at the bottom of the reducer, and the output shaft of the motor is fixedly connected to the bottom of the transmission rod through the reducer.

[0010] As a preferred embodiment of the utility model of a high-efficiency stirring device for sewage treatment, a plurality of drain outlets are fixedly installed at the bottom of the stirring tank, and supporting legs are fixedly installed at the bottom of the stirring tank.

[0011] As a preferred embodiment of the utility model of a high-efficiency stirring device for sewage treatment, the stirring structure includes a mounting block, a rotary damper is fixedly mounted on one side of the mounting block, and a stirring blade is rotatably mounted on one side of the rotary damper.

[0012] As a preferred embodiment of the utility model of a high-efficiency stirring device for sewage treatment, a plurality of weight-reducing grooves are provided inside the stirring blade, and a spoiler is fixedly installed at one end of the weight-reducing groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model changes the position of the adjustment seat on the top of the fixed seat through the first hydraulic rod. When the position of the adjustment seat is changed, the turntable changes the angle of the first connecting rod inside the mounting sleeve through the cooperation among the connecting column, the second ball head, the first ball head, the connecting arm and the second connecting rod, thereby changing the angle of the stirring structure. In this process, the top structure of the turntable is ensured to rotate freely by rotating the turntable installed on the top of the adjustment seat, and the turntable and the connecting arm are movably connected by the second ball head and the first ball head, so that the range of movement between the connecting arm and the turntable is larger. The extension and retraction of the second hydraulic rod can change the angle between the first connecting rod and the second connecting rod, thereby changing the plane angle of the stirring structure, and finally achieving the purpose of changing the diameter of the stirring area. It has the advantages of controlling the fluid dynamics characteristics inside the liquid by changing the stirring diameter, thereby accurately adjusting the reaction process, etc. In summary: the equipment can flexibly change the angle and stirring diameter of the stirring structure, which solves the problems that uniform flow and shear distribution cannot be formed in the entire reaction tank, the mixing effect is limited, and mixing dead corners are prone to occur.

[0024] During use, the position of the adjustment seat 209 on the top of the fixed seat 201 is changed by the first hydraulic rod 208. When the position of the adjustment seat 209 is changed, the turntable 210 changes the angle of the first connecting rod 204 inside the mounting sleeve 203 through the cooperation among the connecting column 211, the second ball head 212, the first ball head 207, the connecting arm 206, and the second connecting rod 205, thereby changing the angle of the stirring structure 3. In this process, the turntable 210 is rotatably installed on the top of the adjustment seat 209 to ensure that the top structure of the turntable 210 can rotate freely, and the turntable 210 and the connecting arm 206 are movably connected by the second ball head 212 and the first ball head 207, so that the range of movement between the connecting arm 206 and the turntable 210 is larger. In summary, the device can flexibly change the angle of the stirring structure 3, which solves the problem that a uniform flow and shear distribution cannot be formed in the entire reaction tank, the mixing effect is limited, and mixing dead corners are prone to occur.

During the stirring process, the rotating stirring blade 303 can prevent the sewage from generating vortexes while improving the stirring efficiency. The rotation speed of the stirring blade 303 can be reduced by the rotary damper 302 to prevent the stirring blade 303 from rotating too fast.
