Description

Technical Field

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

[0002] Hot water boilers are widely used in industrial and civil sectors and are important thermal energy equipment. Their operating efficiency and service life are closely related to water quality treatment, and the proper addition of water treatment agents plays a crucial role in ensuring the safe and economical operation of the boiler. During the operation of hot water boilers, water quality problems can lead to many adverse consequences. For example, calcium and magnesium ions in the water can form scale on the inner wall of the boiler. Scale has extremely poor thermal conductivity, which hinders heat transfer, reduces thermal efficiency, and increases energy consumption. At the same time, dissolved oxygen and other substances in the water can corrode the boiler metal, weaken the boiler's structural strength, and in severe cases, may even cause safety accidents. Currently, when adding boiler water treatment agents, solid agents are usually first prepared into a solution and then pumped into the boiler. However, existing agent dosing devices have significant shortcomings; on the one hand, it is impossible to sieve the solid agents during the dosing process. If the solid chemical particles are not uniform, the larger particles will dissolve significantly slower than the smaller particles. This leads to inconsistent dissolution times, affecting the efficiency of boiler water dosing and making it difficult to ensure stable dosing concentrations. Furthermore, some chemicals are prone to caking due to moisture during storage. Existing dosing devices generally lack effective crushing and stirring mechanisms, making it impossible to handle caking chemicals. This results in incomplete dissolution of these caking chemicals, further reducing their efficiency and increasing the risks associated with boiler operation. Utility Model Content

[0018] Example 1

[0019] like Figures 1 to 4As shown, this utility model discloses a boiler water treatment chemical dosing device. The technical solution includes a base plate 1, a control module 2 fixedly installed on one side of the top of the base plate 1, a chemical tank 3 fixedly installed on the top of the base plate 1, and casters 8 fixedly installed at the four corners of the bottom of the base plate 1. The casters 8 make the entire dosing device easy to move, improving the flexibility and convenience of the dosing device. An inverted U-shaped fixing seat 4 is fixedly installed on the top of the chemical tank 3. An observation window 13 is provided on the side of the chemical tank 3. Through the observation window 13, the staff can easily observe the liquid level of the chemical in the chemical tank 3 at any time, know the remaining amount of chemical in time, so as to prepare to replenish the chemical in advance and ensure the continuity of the dosing work. The dosing port on the lower side of the chemical tank 3 is connected to one end of the dosing pipe 7. A dosing pump 6 is installed on the dosing pipe 7. The dosing pump 6 is fixedly installed on the side of the chemical tank 3. A filtering, crushing and stirring mechanism 5 is installed on the chemical tank 3.The filtration, pulverizing, and stirring mechanism 5 includes a motor 51, a rotating rod 52, a feed hopper 53, a filter cylinder 54, pulverizing blades 55, a fixed rod 56, and a stirring rod 57. The motor 51 is fixedly installed in the middle of the top of the fixed base 4. The output shaft of the motor 51 passes through a through hole in the top of the fixed base 4 and is fixedly connected to the upper end of the rotating rod 52. The lower end of the rotating rod 52 is rotatably connected to the middle of the bottom of the medicine tank 3. The filter cylinder 54 is fixedly installed in the top of the medicine tank 3. The bottom of the filter cylinder 54 has a through hole that matches the rotating rod 52. The top of the medicine tank 3 has a through hole with a diameter equivalent to that of the filter cylinder 54. Pulverizing blades 55 are fixedly installed on the rotating rod 52. Located inside the filter cartridge 54, the pulverizing blade 55 includes a base plate 553. Two large pulverizing blades 551 are symmetrically arranged on the side of the base plate 553, along with four small pulverizing blades 552. Two pulverizing plates 554 are symmetrically arranged on the side of the base plate 553, with one outer end of the pulverizing plate 554 being stepped. Through the large pulverizing blades 551, small pulverizing blades 552, and pulverizing plates 554 of different sizes and lengths, the solid reagent inside the filter cartridge 54 can be thoroughly pulverized, avoiding residue. Several fixing rods 56 are fixedly installed on the side of the lower end of the rotating rod 52. One outer end of each fixing rod 56 is connected to the stirring rod 57. A feed hopper 53 is fixedly installed on the top of the medicine tank 3, and the feed hopper 53 connects to the inside of the filter cartridge 54. A cover plate 9 is sleeved on the outer side of the upper end of the rotating rod 52. The cover plate 9 cooperates with the feed hopper 53. Two U-shaped handles 10 are fixedly installed on the top of the cover plate 9. The cover plate 9 can seal the feed hopper 53 during crushing and stirring to prevent the medicine from splashing to the outside. Two iron plates 11 are fixedly installed on the top of the cover plate 9. A magnetic plate 12 that cooperates with the two iron plates 11 is fixedly installed on the top of the fixed base 4. The iron plates 11 and the magnetic plate 12 can attract the cover plate 9 to the fixed base 4, which facilitates the addition of solid medicine. The dosing pump 6 is connected to the electric... The motor 51 is electrically connected to the control module 2. The motor 51 drives the rotating rod 52 to rotate. The pulverizing blades 55 on the rotating rod 52 are located inside the filter cartridge 54, pulverizing the solid reagent entering the filter cartridge 54 from the feed hopper 53. The pulverized reagent falls into the reagent tank 3 through the through-hole on the filter cartridge 54. The fixing rod 56 and stirring rod 57 fixed to the lower side of the rotating rod 52 stir the reagent solution in the reagent tank 3, ensuring that the reagent is fully dissolved and uniformly mixed in the water. The solid reagent is pulverized and filtered during addition, ensuring uniform particle size and consistent dissolution time, thereby guaranteeing the stability of the dosing concentration and improving the boiler water treatment effect.

[0020] The working principle of this utility model is as follows: When water treatment agents need to be added to the boiler, the solid agent is poured from the feed hopper 53 into the filter cartridge 54. The cover plate 9 is placed over the feed hopper 53 to seal it. The control module 2 controls the motor 51 to work, causing the output shaft of the motor 51 to drive the rotating rod 52 to rotate at high speed. The crushing blades 55 on the rotating rod 52 rotate together with the rotating rod 52. Since the crushing blades 55 include a base plate 553, the two large crushing blades 551 symmetrically arranged on the side of the base plate 553 first pre-crush the larger pieces of solid agent, dividing them into smaller pieces. Then, the four small crushing blades 552 arranged on the side of the base plate 553 further refine and crush these small pieces of agent, making the particles more fine. The substrate 553 has two symmetrically arranged crushing plates 554 on its side, with one outer end being stepped. During rotation, these plates can squeeze and knead the medicine, further crushing it into finer particles. This ensures that the solid medicine is thoroughly crushed within the filter cartridge 54. The crushed medicine falls into the medicine tank 3 through the through hole at the bottom of the filter cartridge 54. As the rotating rod 52 continues to rotate, the fixing rod 56 and stirring rod 57 fixed to the lower side of the rotating rod 52 also rotate. The stirring rod 57 rotates in the medicine solution within the medicine tank 3, stirring the solution. During stirring, the medicine continuously tumbles and mixes in the water, ensuring that the medicine is fully dissolved and evenly distributed in the solution, thus guaranteeing the stability of the medicine solution concentration.

[0021] Once the chemical solution in tank 3 is prepared, the dosing pump 6 is activated via control module 2 to transport the solution from tank 3 to the boiler through dosing pipe 7, completing the dosing operation. Throughout the dosing process, staff can monitor the chemical level in tank 3 at any time through observation window 13. If the level is low, the solution is replenished promptly to ensure continuous dosing.

[0022] When adding solid reagents, the operator can lift the cover plate 9 by the handle 10. At this time, the iron plate 11 on the top of the cover plate 9 will attract each other to the magnet plate 12 on the top of the fixed seat 4, so that the cover plate 9 is attracted to the fixed seat 4, making it easy for the solid reagents to be added into the feed hopper 53. After the solid reagents are poured into the feed hopper 53, the cover plate 9 is lowered to seal the feed hopper 53 and prevent the reagents from splashing out during the crushing and stirring process.
