DETAILED DESCRIPTION
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figs. 1-3 As shown, a dosing device for improving the feedwater quality of a gas-fired boiler includes a boiler tank 1. A cover 2 is fixedly connected to the upper surface of the boiler tank 1. A drive motor 3 is fixedly installed in the middle of the upper surface of the cover 2. The same adjustment mechanism 4 is provided on the lower surface of both the drive motor 3 and the cover 2. A rotating rod 5 is provided inside the boiler tank 1. Paddle blades 6 are evenly distributed and fixedly installed on the surface of the rotating rod 5.
[0021] By adopting the above technical solution, the rotation of the rotating rod 5 can cause the blade 6 to rotate, thereby stirring and mixing the medicine and water, and increasing the mixing rate.
[0022] Furthermore, the adjustment mechanism 4 includes a cross rod 401 installed through the bottom end of the drive motor 3 and the cover 2. A sleeve 402 is slidably sleeved on the surface of the cross rod 401. The shape of the cavity in the middle of the sleeve 402 matches the cross rod 401. The bottom end of the sleeve 402 is fixedly connected to the rotating rod 5.
[0023] By adopting the above technical solution, the drive motor 3 can drive the cross rod 401 to rotate, and the sleeve 402 is slidably connected to the cross rod 401 through the cross-shaped cavity. Under the cross-shaped transmission, the sleeve 402 also rotates, which can drive the rotating rod 5 to rotate.
[0024] Furthermore, the adjustment mechanism 4 also includes a fixing plate 403 fixedly installed in the middle of the surface of the sleeve 402. An extension rod 404 is fixedly connected to both the left and right sides of the upper surface of the fixing plate 403. The extension rod 404 is shaped like a "T". The adjustment mechanism 4 also includes a fixing ring 405 fixedly installed in the middle of the lower surface of the cover 2 and fixedly installed to the cross rod 401 and the outer side of the sleeve 402. A groove 406 is circumferentially opened on the lower surface of the fixing ring 405. A recessed groove 407 is correspondingly opened on the front and rear sides of the inner surface of the groove 406. The recessed groove 407 is shaped like a wave. The upper end of the extension rod 404 slides inside the groove 406. The horizontal bars on both sides of the "T" shape of the extension rod 404 are slidably set inside the recessed groove 407.
[0025] By adopting the above technical scheme, during the rotation of the sleeve 402, the fixed plate 403 will also drive the extension rod 404 to move around inside the groove 406 of the fixed ring 405. When the extension rod 404 moves, the rod body will be affected by the wavy sink groove 407 and will move up and down, thereby pulling the sleeve 402 to move up and down, which can drive the rotating rod 5 and the paddle 6 to move up and down. Moreover, due to the cross-shaped nested connection of the cross rod 401 and the sleeve 402, the rotation will not be affected during the up-and-down movement of the sleeve 402, so that the rotating rod 5 and the paddle 6 can rotate and stir the water and the medicine in an up-and-down movement manner.
[0026] Further, the outer surface of the boiler tank 1 is fixedly installed with a diaphragm pump 7 at the leftmost side. The upper end of the diaphragm pump 7 is fixedly connected with a conveying pipe 8, and the conveying pipe 8 is in communication with the inside of the boiler tank 1.
[0027] By adopting the above technical scheme, the diaphragm pump 7 sucks the fluoride-lowering medicament and the alkalinity adjusting agent in the external box body, and adds them into the boiler tank 1 through the conveying pipe 8, so that the medicament and the water are mixed, which can improve the quality of the feed water and reduce harmful impurities and hardness in the feed water.
[0028] Further, the outer surface of the boiler tank 1 is fixedly connected with a feed water pipe 9 at the right side and upper side, and is fixedly connected with a discharge pipe 10 at the right side and lower side.
[0029] By adopting the above technical scheme, the feed water pipe 9 can be used to add condensed water into the boiler tank 1, and the discharge pipe 10 can be used to discharge the processed water in the boiler tank 1.
[0030] Working principle: when using the medicine feeding device for improving water quality of gas boiler feed water, first, use the feed water pipe 9 to add the water that needs to be processed into the boiler tank 1, then start the diaphragm pump 7 and the driving motor 3 at the same time, the diaphragm pump 7 sucks the fluoride reducing agent and alkalinity adjusting agent in the external box, adds them into the boiler tank 1 through the conveying pipe 8, mixes the medicine and water, drives the cross rod 401 to rotate by the driving motor 3, the cross rod 401 drives the sleeve 402 to rotate by its cross shape, and drives the rotating rod 5 and the paddle 6 to rotate, stirs and mixes the water and medicine in the boiler tank 1, in the process of rotating the sleeve 402, the fixed plate 403 drives the extension rod 404 to move in the groove 406 of the fixed ring 405, when the extension rod 404 moves, the rod body moves up and down under the influence of the wave-shaped sink 407, which drives the sleeve 402 to move up and down, drives the rotating rod 5 and the paddle 6 to move up and down, and because of the cross-shaped nested connection of the cross rod 401 and the sleeve 402, the sleeve 402 moves up and down without affecting the rotation, which can make the rotating rod 5 and the paddle 6 rotate and stir the water and medicine up and down, so that the added medicine and water are quickly and uniformly mixed, after mixing the medicine, the harmful impurities and hardness in the water are reduced, so as to improve the water quality of the boiler feed water, finally, the processed water is discharged through the discharge pipe 10, which is the working principle of the medicine feeding device for improving water quality of gas boiler feed water.
