Description

Technical Field

[0001] The utility model relates to the technical field of lithium fluoride tail gas treatment, in particular to a stirring reaction device for lithium fluoride tail gas treatment equipment. Background Technique

[0002] Lithium fluoride is an inorganic salt with the chemical formula LiF and a molecular weight of 25.94. It is an alkali metal halide, a white crystal at room temperature, slightly soluble in water. It is used in the nuclear industry, enamel industry, optical glass manufacturing, desiccant, flux, etc. It can be prepared by crystallizing lithium carbonate or lithium hydroxide with hydrofluoric acid in a lead dish or a platinum dish.

[0003] Upon retrieval, the publication (announcement) number: CN212680590U discloses a stirring reaction device for lithium fluoride tail gas treatment equipment. The lower left end of the kettle body is connected with an air inlet pipe, the middle part of the upper end of the kettle body is connected with a motor, the output end of the motor penetrates into the kettle body, and the upper side inside the kettle body is connected with a partition plate. The output end of the motor passes through the partition plate through a shaft rod and extends to the lower end inside the kettle body. Two sides of the upper end of the partition plate are respectively provided with a first air outlet, and a first filter screen is arranged in the first air outlet. The upper end of the first air outlet is connected with a tail gas treatment pipeline on the partition plate. The lower end in the tail gas treatment pipeline is connected with a first fan, and a second filter screen is connected above the first fan; by performing multiple treatments on the tail gas, the content of air pollutants discharged is sufficiently reduced, and the treatment efficiency and air outlet efficiency of the tail gas in the kettle body are improved, changing the phenomenon of low traditional tail gas treatment efficiency and effectively and efficiently completing the treatment work.

[0004] Although the above solution sufficiently reduces the content of air pollutants discharged by performing multiple treatments on the tail gas, and the treatment efficiency and air outlet efficiency of the tail gas in the kettle body are improved, the particulate matter in the tail gas is easily attached to the inner wall of the kettle body, resulting in a decline in the subsequent tail gas treatment effect. For this reason, we propose a stirring reaction device for lithium fluoride tail gas treatment equipment. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a stirring reaction device for lithium fluoride tail gas treatment equipment, and by setting a stirring unit and a cleaning unit, to solve the problem that the particulate matter in the tail gas is easily attached to the inner wall of the kettle body, resulting in a decline in the subsequent tail gas treatment effect.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A stirring reaction device for lithium fluoride tail gas treatment equipment includes a main body unit, and further includes a stirring unit, a cleaning unit and an exhaust unit arranged in the main body unit, and an infusion unit arranged below the main body unit;

[0008] The stirring unit includes a rotating shaft movably arranged inside the main body unit, a driving motor installed at the input end of the rotating shaft, and stirring blades installed on the side wall of the rotating shaft;

[0009] The cleaning unit includes a connecting rod installed on the side wall of the rotating shaft, and a cleaning member arranged at the opposite end of the connecting rod and the rotating shaft.

[0010] Preferably, the main body unit includes a reaction kettle, support feet installed at the bottom of the reaction kettle, and an intake pipe installed on the side wall of the main body unit and communicating with the inside of the main body unit.

[0011] Preferably, the main body unit further includes a sewage discharging member arranged below the reaction kettle, a sewage discharging pipe installed at the bottom of the reaction kettle, and a regulating valve movably arranged inside the sewage discharging pipe.

[0012] Preferably, the cleaning member includes a connecting plate installed at the end of the rotating shaft, and cleaning soft brushes installed on the opposite side walls of the connecting plate.

[0013] Preferably, there are several cleaning members, and the several cleaning members are arranged in a circular array with respect to the rotating shaft.

[0014] Preferably, the exhaust unit includes a tail gas treatment pipe installed on the inner top wall of the reaction kettle, a filter screen installed on the inner wall of the tail gas treatment pipe, an air suction fan arranged inside the tail gas treatment pipe, and an exhaust pipe installed on the top of the reaction kettle and communicating with the inside of the tail gas treatment pipe.

[0015] Preferably, the liquid infusion unit includes a liquid storage pipe arranged inside the reaction kettle, an infusion pipe installed at the input end of the liquid storage pipe, and a liquid discharging nozzle installed on the side wall of the liquid storage pipe.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] In the present utility model, through the arranged stirring unit and cleaning unit, when lithium fluoride tail gas enters the reaction kettle through the intake pipe, the liquid storage pipe sprays the stored reaction solution onto the gas, and the particulate matter generated after reacting with the harmful substances in the gas falls under the action of gravity. Finally, by opening the regulating valve, the solid particulate matter can be discharged from the sewage discharging pipe; when treating the lithium fluoride tail gas, the driving motor drives the rotating shaft to rotate, so that the stirring blades fully stir the tail gas. During the stirring process, the connecting rod rotates synchronously with the rotating shaft, and the cleaning soft brush sweeps off the solid particles attached to the inner wall of the reaction kettle, thereby preventing the particulate matter in the tail gas from adhering to the inner wall of the kettle body and ensuring the subsequent tail gas treatment effect.
