Description

Technical Field

[0001] The utility model relates to the technical field of wet waste gas purification, and in particular to a high-position dosing device for a spray system. Background Art

[0002] Waste gas purification mainly refers to the work of treating industrial waste gas such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc. At present, most waste gas spray washing purification equipment uses manual dosing or simple automatic dosing barrels, and the dosing method of this automatic dosing barrel is to use a dosing pump for dosing. When there are many impurities in the dosing barrel, the dosing pump is easy to damage and troublesome to maintain. Impurities will also damage the purification equipment, and at the same time affect the stability of the waste gas purification effect, causing intermittent emissions to exceed the standard. Therefore, it is necessary to improve the stability of the dosing system.

[0003] After searching, the Chinese patent announcement number is CN216878969U, which discloses a high-position dosing device for an exhaust gas spray washing purification system. In this patent, the positions of the water supply port, the drain port, the dosing port and the overflow port are cleverly designed on the box body, and the dosing method is gravity self-flow. The dosing flow rate is controlled by the solenoid valve, which can not only improve the stability of dosing, but also reduce energy consumption by reducing the dosing pump, and reduce the use and maintenance costs;

[0004] However, from the working principle of the patent, it can be seen that when the device is working, the liquid to be added is first put in, and then an appropriate amount of water is added, and then mixed. However, this adding method is prone to the added liquid being precipitated at the bottom of the inner cavity of the box, resulting in insufficient mixing during subsequent mixing. At the same time, during the use of the box, the inner wall of the box produces dirt and other impurities due to the special reaction of the liquid and cannot be effectively cleaned. Utility Model Content

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 5As shown in the figure, a high-position chemical dosing device for a spraying system includes a housing 1. Multiple struts 2 are fixedly installed at the bottom of the housing 1, and the struts 2 are evenly fixedly installed at the bottom of the housing 1. The middle part of the bottom plate 3 is of a hollow design, so that during use, the whole device can be quickly moved by a forklift passing through the hollow part in the middle of the bottom plate 3. The bottom of the strut 2 is fixedly installed with a bottom plate 3. A discharge pipe 4 is fixedly installed at the bottom of the housing 1. The top of the discharge pipe 4 penetrates into the bottom of the inner cavity of the inner box 15. Sealing gaskets are provided at the joints of the discharge pipe 4 with the inner box 15 and the housing 1. Thus, during use, the mixed liquid medicine in the inner box 15 can be quickly discharged by means of the discharge pipe 4 and the first valve 5. A first valve 5 is fixedly installed in the middle of the part of the discharge pipe 4 extending out of the bottom of the housing 1. Multiple grooves 6 are opened at the top of the housing 1. A first cover plate 7 is placed on the top of the housing 1. The shape of the bottom of the first cover plate 7 matches the shape of the inner cavity of the groove 6, and the cross-sectional area of the first cover plate 7 matches that of the housing 1. The cross-sectional area of the second cover plate 16 matches that of the inner box 15. A switch 8 is fixedly installed on the front side of the first cover plate 7. The switch 8 is electrically connected to the motor 9 through a wire. The bottom of the motor 9 is detachably installed with the top of the cylinder 24. Thus, during use, the motor 9 is controlled to start by pressing the switch 8, thereby controlling the rotation of the cylinder 24 and the stirring blades 25, and further mixing the liquid medicine and water flow in the inner cavity of the inner box 15. A motor 9 is fixedly installed in the middle of the top of the first cover plate 7. Circular holes matching the diameters of the connecting pipe 12, the cylinder 24, and the short pipe 14 are opened at the tops of the first cover plate 7 and the second cover plate 16. A water tank 10 is fixedly installed on the left side of the top of the first cover plate 7. The bottom of the inner cavity of the water tank 10 is communicated with the top of the inner cavity of the water storage block 17 through the second valve 11 and the connecting pipe 12. Thus, during use, when the second valve 11 is opened, the liquid medicine in the water tank 10 can flow into the water storage block 17 through the connecting pipe 12. The second valve 11 is fixedly installed at the bottom of the water tank 10, and the second valve 11 is fixedly installed with a connecting pipe 12 at the bottom. An inlet block 13 is fixedly installed on the right side of the top of the first cover plate 7. The middle part of the inlet block 13 is of a hollow design. Threads are provided at the top of the inner side wall of the inlet block 13. The bottom of the short pipe 14 penetrates into the top of the inner cavity of the inner box 15. Thus, during use, it is convenient to connect with an external water source pipe by means of the threads on the inner side wall of the inlet block 13, and the water flow can be quickly introduced into the inner box 15 in cooperation with the short pipe 14. The bottom of the inlet block 13 is fixedly installed with a short pipe 14. The inner cavity of the housing 1 is detachably installed with an inner box 15. A second cover plate 16 is placed on the top of the inner box 15. A water storage block 17 is fixedly installed in the middle of the left inner side wall of the inner box 15. A sealing block 18 is placed at the bottom of the inner cavity of the water storage block 17. A strip-shaped groove 19 is opened on the right side of the water storage block 17. The shape and size of the sealing block 18 are larger than those of the strip-shaped groove 19. The gravity of the floating plate 20 is less than that of the sealing block 18, and the buoyancy of the floating plate 20 is greater than that of the sealing block 18. Thus, during use, as the water flow in the inner box 15 increases, the floating plate 20 also moves upward, thereby driving the sealing block 18 to move upward. When the sealing block 18 moves to the topmost position, it cannot block the strip-shaped groove 19.At this time, the liquid medicine in the inner cavity of the water storage block 17 can flow into the inner box 15 from the strip-shaped groove 19. A floating plate 20 is fixedly installed on the right side of the sealing block 18 through the strip-shaped groove 19. A filter plate 21 is detachably installed at the bottom of the inner cavity of the inner box 15. Collection grooves 22 are formed around the top of the filter plate 21. A handle 23 is fixedly installed in the middle of the top of the filter plate 21. The four peripheral edges of the top of the filter plate 21 are designed as inclined surfaces. Therefore, when in use and after use, the filter plate 21 can be removed from the bottom of the inner cavity of the inner box 15 through the handle 23. When removed, the impurities adhering to the inner wall of the inner box 15 are scraped off by the inclined surface design around the top of the filter plate 21 and collected and stored by the collection grooves 22. A cylinder 24 is arranged in the middle of the inner cavity of the inner box 15, and a plurality of stirring blades 25 are fixedly installed at the bottom of the cylinder 24.,

[0027] Working principle: When in use, first, a hose connected to an external water source is fixedly installed at the top of the inner cavity of the water inlet block 13 through threads, and then the second valve 11 is opened, so that the liquid medicine in the water tank 10 flows into the water storage block 17 through the connecting pipe 12. At this time, the sealing block 18 in the inner cavity of the water storage block 17 moves down to the bottom of the inner cavity of the water storage block 17 under its own gravity, and the strip-shaped groove 19 is blocked by the volume of the sealing block 18. After a period of time, the second valve 11 is closed. Thus, each time the liquid medicine is mixed, only a certain amount of liquid medicine can be mixed. Then, the external water source valve is opened, so that the water flows into the inner cavity of the inner box 15 through the water inlet block 13 and the short pipe 14. During the flowing process, since the materials of the outer shell 1 and the inner box 15 are both synthetic plastics with good transparency, the water in the inner box 15 gradually increases. When the top of the water flow rises to the floating plate 20, at this time, the staff can probably see from the outside. Thus, the start switch 8 is pressed to start the motor 9 to drive the cylinder 24 and the stirring blades 25 to rotate. At the same time, the water flow in the inner box 15 drives the floating plate 20 to move up, so that the sealing block 18 moves up in the inner cavity of the water storage block 17, resulting in the opening of the strip-shaped groove 19. The liquid medicine in the inner cavity of the water storage block 17 can flow out and be mixed into the water flow in the inner box 15. Cooperating with the rotating cylinder 24 and stirring blades 25 at this time, the mixing and stirring can be started when the liquid medicine is just poured in, so as to improve the mixing degree of the liquid medicine and the water flow. When the water flow in the inner box 15 is close to the top of the inner cavity of the inner box 15, the external water flow valve is closed. After the motor 9 works for a period of time, the switch 8 is closed. At this time, the liquid medicine and the water flow in the inner box 15 are fully mixed, and the mixed liquid in the inner cavity of the inner box 15 can be discharged and used through the discharge pipe 4 by opening the first valve 5;

[0028] After the whole device works for a period of time, the connecting pipe 12 and the cylinder 24 can be rotated and separated to be separated from the second valve 11 and the motor 9. At this time, the first cover plate 7 and the second cover plate 16 can be opened smoothly. Then, the handle 23 is manually pulled to take out the filter plate 21 from the bottom of the inner cavity of the inner box 15. By using the inclined surface design at the top of the filter plate 21, the impurities adhering to the inner wall of the inner box 15 are scraped off during the upward movement of the filter plate 21. When the filter plate 21 moves to the water storage block 17, the filter plate 21 is tilted so that it passes through the water storage block 17.

[0029] In summary, compared with general similar devices, this high-position dosing device for the spray system has the advantages of automatically and efficiently mixing the spray liquid and efficiently cleaning impurities on the inner wall of the box.
