Safe and environmental-friendly sewage treatment stirring kettle

Abstract

The invention discloses a safe and environmental-friendly sewage treatment stirring kettle which comprises a bucket body, an upper cover, a support plate, a frequency conversion motor, a stirring mechanism, a support rack, a motor, a screw nut, a connecting rod, a screw rod, a bottom plate and a base, wherein the stirring mechanism comprises a stirring shaft, T-shaped blades, a fixing platform, acompression spring and a moveable sleeve; a guide rod is mounted at the upper end of the base; a guide hole is vertically formed right above the guide rod on a side of the bottom plate; the guide rodis externally sleeved by a buffer spring. A conventional welding mode is replaced by an insertion and clamping mode when stirring blades are fixed, then roots of broken stirring blades can be conveniently taken out, new stirring blades can be mounted conveniently, convenience is brought to repairing of the stirring blades, up and down movement of the stirring mechanism is achieved, positions can be adjusted according to practical demands, very good damping effects can be achieved by magnets and springs, movement and positioning can be facilitated, a good fixing effect can be achieved, and theworking stability of a stirring kettle can be improved.

Description

technical field [0001] The invention relates to a stirred tank, in particular to a safe and environment-friendly sewage treatment stirred tank. Background technique [0002] Whether it is life or production, water resources are used. When these water resources are used, they become waste water and sewage. People produce a lot of sewage every year, but most of this part of sewage will be directly discharged without entering Sewage treatment plants flow directly into rivers, so saving the source of water is an urgent task, but saving water can not only be done by using less water every day, but also by treating the sewage so that it can be reused, even if it cannot be reused. To have an impact on the existing environment, many steps will be involved in the sewage treatment technology, various oxidation ponds and sedimentation ponds will be used, and large sewage treatment plants will also occupy a large area, but we cannot just To rely on sewage treatment plants for sewage tr...

[0002] Whether it is life or production, water resources are used. When these water resources are used, they become waste water and sewage. People produce a lot of sewage every year, but most of this part of sewage will be directly discharged without entering Sewage treatment plants flow directly into rivers, so saving the source of water is an urgent task, but saving water can not only be done by using less water every day, but also by treating the sewage so that it can be reused, even if it cannot be reused. To have an impact on the existing environment, many steps will be involved in the sewage treatment technology, various oxidation ponds and sedimentation ponds will be used, and large sewage treatment plants will also occupy a large area, but we cannot just To rely on sewage treatment plants for sewage treatment, you must also know how to carry out sewage treatment. Therefore, the state recommends that small private factories should build their own sewage treatment equipment and have their own sewage treatment machinery. In traditional sewage treatment technology, sewage must first pass through Precipitation and then dosing, filtration and other steps, the initial technology is to use physical methods to remove relatively large suspended solids and sediments, but this natural precipitation time is too slow, so technicians will add reagents for chemical treatment when there is no edema However, after the reagent is added, it needs to be stirred to make the sewage and the reagent combine more thoroughly. Now is the era of mechanization, so mechanical stirring has become the mainstream. The quality of the stirring effect depends on the quality of the stirring blade. During the stirring process, the sewage It will have an impact on the paddle, and the impurities and chemicals in the sewage will corrode the paddle, so the general stirring mechanism is the most easily damaged part. Although the traditional stirring mechanism is also a separate structure between the stirring shaft and the paddle, it often stirs The blades are all installed as a whole. Once any of the traditional three-blade blades is damaged, the whole must be replaced, and the installation of the traditional blades is not convenient.

Moreover, when the stirring tank is working or moving, it will generate a lot of vibration itself or outside, which will have a great impact on the stirring tank itself, and the instability of the stirring tank will also affect the stirring effect
