Description

TECHNICAL FIELD

[0001] The utility model relates to a boiler water treatment agent reaction tank belongs to boiler water treatment agent production technical field. BACKGROUND

[0002] The boiler water treatment agent is a boiler descaling agent, which is composed of agents with chelation, cleaning and dispersion effects, and has dual effects of cleaning and corrosion inhibition. During the production of the boiler water treatment agent, mixing reaction production is needed through a reaction tank. The existing treatment agent reaction device, such as the boiler water treatment agent reaction tank disclosed in Chinese Patent Publication No. CN116408030A, includes a reaction tank, a feed pipe arranged on the upper surface of the reaction tank, a cover arranged on the top surface of the feed pipe, a discharge pipe arranged on the bottom surface of the reaction tank, and a discharge valve arranged on the surface of the discharge pipe. The reaction tank can rotate and remove the top cover of the collection bucket, and can carry the collection bucket to the lower end of the discharge pipe. By controlling the discharge valve, the reaction mixture inside the reaction tank can be discharged into the collection bucket through the discharge pipe, which facilitates subsequent treatment and does not cause indoor environmental pollution. Another example is the boiler water treatment agent reaction tank disclosed in Chinese Patent Authorized Publication No. CN219722874U, in which the top of the tank body is provided with an upper cover, a medicine inlet, and a driving mechanism. This structure can automatically discharge medicine and collect undissolved soft water agent powder. However, the reaction tank of the above structure cannot fully dissolve the solid raw materials into the water body, which easily causes large granular particles to be filtered and retained, resulting in the finished boiler water treatment agent not meeting the standard concentration. CONTENT OF THE UTILITY MODEL

[0003] To solve the above problems, the utility model provides a boiler water treatment agent reaction tank, which can mix the fluid obtained by mixing the solid raw materials and water, and alternately circulate the fluid for stirring, mixing and grinding, so that the solid raw materials of the boiler water treatment agent are fully dissolved into the water.

[0004] The utility model discloses a boiler water treatment agent reaction tank, which comprises:

[0005] A reaction tank body is provided with an electric stirrer on the top, and a bottom valve is arranged on the bottom.

[0006] A slurry dispersion unit includes a dispersion tank with a discharge window along the inner edge of its bottom. A flange ring is integrally formed on the outside of the dispersion tank above the discharge window. The dispersion tank is fitted into the top of a reaction tank, and the flange ring is fastened to the reaction tank with bolts. A cover is fixed to the top of the dispersion tank, and a sealing unit is provided on the upper inner side of the dispersion tank. A limit bearing is fixed at the center of the bottom of the inner side of the dispersion tank. A grinding cone is rolled along the lower inner side of the dispersion tank. A reduced-diameter section is integrally formed at the center of the bottom surface of the grinding cone to be installed with the limit bearing. A drive rod is integrally formed at the top of the grinding cone. The drive rod moves through the sealing unit and connects to a grinding drive unit. A first flange and a second flange are provided on the upper part of the grinding cone in the dispersion tank. A grinding gap is provided between the grinding cone and the inner wall of the dispersion tank.

[0007] A circulation pipe assembly, which includes a feed pump, the input end of which is connected to the bottom of the reaction vessel, and the top of which is connected to a second flange;

[0008] A feeding unit, which is connected to a first flange.

[0009] The feeding unit feeds liquid or solid-liquid mixture into the dispersion tank, which then enters the reaction tank. Premixing is achieved by an electric agitator, resulting in a premixed fluid. Large particles are then settled to the bottom of the reaction tank via static sedimentation or low-speed agitation. Next, a pump pumps the fluid with a high content of large particles back into the dispersion tank through a second flange. The grinding drive unit, composed of a drive motor and a reduction gear, drives the grinding cone to rotate. When the fluid with a high content of large particles enters between the dispersion tank and the grinding cone, the continuous rotation of the grinding cone grinds the large particles within the grinding gap. The ground fluid then passes through the grinding gap and re-enters the reaction tank through the discharge window at the bottom of the dispersion tank, where it is again mixed by the electric agitator. The sealing unit creates a sealing surface on the upper part of the grinding cone and continuously pumps material, creating pressure inside the dispersion tank and improving the grinding efficiency of the grinding cone.

[0010] Furthermore, the feeding unit is a premixing vessel; the bottom valve of the premixing vessel is connected to the first flange; a certain amount of water and solid raw materials are added into the premixing vessel and premixed by a stirring paddle to obtain a premixed fluid.

[0011] Further, the sealing unit comprises an upper sealing plate and a lower sealing plate fixed to the dispersion tank by bolts, and the driving rod is provided with a sealing ring between the upper sealing plate and the lower sealing plate; the dispersion tank is provided with an air pressure flange between the upper sealing plate and the lower sealing plate, and the air pressure flange is connected to an air pump; the dispersion tank, the upper sealing plate and the lower sealing plate form an air storage space, the air pump provides a pressure air source, the pressure air source enters the air storage space, and the pressure air source in the air storage space is released slowly through gaps formed by the driving rod and the upper sealing plate and gaps formed by the driving rod and the lower sealing plate, so that the driving rod and the lower sealing plate are air-tightly closed.

[0012] Further, the upper sealing plate and the lower sealing plate are pressed against the dispersion tank through a sealing ring; the upper sealing plate and the lower sealing plate can be sealed against the inner wall of the dispersion tank through the sealing ring; and thus an air pressure space is formed between the upper sealing plate and the lower sealing plate, so that the pressure gas entering the air pressure space can seal the gaps formed by the driving rod and the lower sealing plate.

[0013] Further, the reaction tank body is externally fixed with an enclosure through a limiting bearing, and the reduced diameter portion is movably inserted into the enclosure; when the grinding cone and the dispersion tank cooperate, the pre-mixed fluid entering the grinding gap is ground by the grinding cone, the fluid passes through the grinding cone and can be isolated from the limiting bearing after being ground.

[0014] Further, the feeding unit comprises a first flange connected to a water supply metering pipeline, and further comprises a raw material feeding hopper arranged at the top of the reaction tank body; during production, the water supply metering pipeline sends water into the dispersion tank to flush the inside of the dispersion tank, at the same time, the metered water enters the reaction tank body after passing through the dispersion tank, at the same time, the electric stirrer is started, and the solid raw material components after completion of metering are put into the reaction tank body through the raw material feeding hopper, and the solid raw material and the water are fully mixed and stirred to obtain a pre-mixed fluid.

[0015] Compared with the prior art, the boiler water treatment agent reaction tank of the utility model can first pre-mix the solid raw material and the water to obtain a fluid, large granular particles in the pre-mixed fluid can be deposited at the bottom of the reaction tank body, and the fluid with a large content of large granular particles can be ground through the material pump, and after grinding, the fluid is stirred and mixed again, and the grinding is continuously performed through the material pump, so that the fluid is alternately circulated for stirring and mixing reaction and grinding, so that the solid raw material of the boiler water treatment agent is fully dissolved in the water, and the undissolved large solid raw material is avoided to be intercepted, thereby ensuring that the finished product of the boiler water treatment agent reaches the production standard.
