Description

Technical Field

[0001] This utility model relates to the field of boiler water treatment technology, specifically to a boiler water treatment chemical dosing device. Background Technology

[0002] In industries such as power, chemical, metallurgy, and heating, boilers, as core thermal energy equipment, directly impact production efficiency and energy supply through their safe and stable operation. Boiler water treatment is a crucial step in ensuring safe boiler operation. By adding appropriate chemicals, such as scale inhibitors, corrosion inhibitors, and oxygen scavengers, scale and corrosion can be effectively prevented inside the boiler, ensuring steam quality and extending boiler lifespan. However, traditional boiler water treatment methods have many shortcomings and fail to meet the higher requirements of modern industry for boiler operation safety, economy, and environmental protection.

[0003] For example, Chinese utility model patent application number 202421528093.0 discloses a dosing device for boiler water treatment. The operator starts a rotary motor, which causes the shaft and cam to rotate. Each rotation of the cam's outer surface contacts the top of the carrying plate. At this point, the carrying plate causes the vertical plate to slide inside the square tube, which in turn causes the moving plate to slide inside the strip groove. Simultaneously, the vertical plate compresses the spring. However, this device still has certain shortcomings.

[0004] When adding chemicals to the cylinder, if the chemicals are only fed through a single storage container, the chemicals tend to accumulate in one place, leading to uneven distribution of chemical concentration and affecting the treatment efficiency of boiler water.

[0005] Therefore, we propose a boiler water treatment chemical dosing device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a boiler water treatment dosing device to solve the problem mentioned in the background art that in the current market, when adding chemicals in a dosing cylinder, only one storage tank is used to feed the chemicals, which makes it easy for the chemicals to accumulate in one place, resulting in uneven distribution of chemical concentration and affecting the treatment efficiency of boiler water.

[0011] Preferably, the stirring assembly includes a first stirring mechanism, a servo motor is mounted above the dosing tank, and the servo motor is connected to the first stirring mechanism via an output shaft at its lower part.

[0012] With the above structural design, the servo motor drives the first stirring mechanism to rotate, which accelerates the mixing of the reagent and the boiler water through mechanical stirring and shortens the dissolution time.

[0013] Preferably, the stirring assembly includes a second stirring mechanism, and the second stirring mechanism is provided with two sets of stirring components, and the second stirring mechanism has an n-shaped structure design.

[0014] With the above structural design, the second stirring mechanism can improve the uniformity of drug mixing when it rotates. Especially for high viscosity or difficult-to-dissolve drugs, it can effectively avoid local precipitation and ensure the consistency of drug concentration.

[0015] Preferably, a slot is provided on the front side of the first sealing cover and the rear side of the second sealing cover, and a sealing gasket is provided on the slot, the first sealing cover and the second sealing cover.

[0016] The above structural design ensures a safe and clean operating environment, prevents external dust from entering the dosing tank, and avoids a decrease in treatment effectiveness due to chemical contamination.

[0017] Preferably, the front side of the first sealing cover and the second sealing cover are connected by a connecting plate. A bearing seat threaded rod passes through the top plate above the connecting plate and is threadedly connected to the top plate. Guide rods are installed on both the left and right sides of the connecting plate and are slidably connected to the top plate.

[0018] With the above structural design, the linkage structure of the threaded rod and the guide rod can simultaneously raise and lower the first sealing cover and the second sealing cover. The cover can be opened or sealed quickly by rotating the threaded rod, which is convenient to operate and highly stable.

[0019] Preferably, the inlet pipe is connected to the interior of the storage tank, and the first branch pipe and the second branch pipe are both connected to the outlet pipe.

[0020] With the above structural design, the first and second branch pipes are used to add the drug to the dosing tank at the first and second dosing ends, respectively, to avoid the accumulation of the drug in a single location and to ensure that the drug is evenly dispersed.

[0021] Compared with the prior art, the beneficial effects of this utility model are: This boiler water treatment dosing device:

[0022] 1. Dual-end dosing for uniform dispersion: Dosing is simultaneously applied from the first dosing end and the second dosing end through the first branch pipe and the second branch pipe respectively, avoiding the accumulation of the agent caused by a single inlet.
