[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6 As shown, a deaerator for boiler water treatment includes a cylinder 101, an inlet pipe 102 fixedly connected to the upper end of the cylinder 101, a rotating shaft 302 rotatably connected coaxially inside the cylinder 101, and a sliding pipe 401 slidably connected to the rotating shaft 302.

[0028] The sliding tube 401 is equipped with a turbulence-inducing mechanism, which includes multiple agitator plates 402. The multiple agitator plates 402 are evenly distributed around the circumference of the sliding tube 401. One end of the agitator plate 402 near the rotating shaft 302 is hinged to the lower end of the sliding tube 401. A transmission mechanism is provided between the agitator plate 402 and the cylinder 101. The transmission mechanism is used to drive the agitator plate 402 to rotate around the rotating shaft 302 and move it up and down at the same time. The rotating shaft 302 drives the sliding tube 401 to rotate, so that the agitator plate 402 rotates around the sliding tube 401 and moves up and down at the same time, thereby promoting the mixing of deoxygenator and water in the cylinder 101, so that the deoxygenator is evenly distributed in the water and reduces the oxygen content in the water.

[0029] The transmission mechanism includes a fixed tube 103 and a sliding groove 404. The fixed tube 103 is coaxially sleeved on the outside of the rotating shaft 302 and fixedly connected to the top wall of the cylinder 101. A rotating ring 403 is rotatably connected to the lower end of the fixed tube 103. Symmetrical connecting rods 405 are hinged on both sides of the rotating ring 403. The connecting rods 405 are hinged to the middle of the stirring plate 402. The sliding groove 404 is opened on the inner wall of the fixed tube 103. The sliding groove 404 is wavy. A sliding block 406 is fixedly connected to the upper end of the sliding tube 401. The sliding block 406 is slidably connected in the sliding groove 404. When the sliding tube 401 rotates, it drives the sliding block 406 to slide with the sliding groove 404, so that the sliding tube 401 slides up and down along the rotating shaft 302, which drives the end of the stirring plate 402 close to the sliding tube 401 to slide up and down, thereby making the stirring plate 402 rotate around the lower end of the connecting rod 405, realizing the effect of stirring the plate 402 moving up and down.

[0030] A power motor 301 is fixedly connected to the upper end of the cylinder 101. The output shaft of the power motor 301 is fixedly connected to the rotating shaft 302. When the power motor 301 is started, it drives the rotating shaft 302 to rotate.

[0031] A feed pipe 201 is fixedly connected to the upper end of the cylinder 101 away from the power motor 301. A feed hopper is fixed to one side of the feed pipe 201. A filter plate 202 is fixedly installed at the lower end of the feed pipe 201. When in use, the deoxidizer is poured into the feed pipe 201 through the feed hopper, and the deoxidizer falls into the cylinder 101 through the filter plate 202.

[0032] A feeding motor 501 is fixedly connected to the upper end of the feed pipe 201. Multiple feeding plates 502 are fixed equidistantly along the output shaft of the feeding motor 501. The lower end of the feeding plate 502 squeezes the filter plate 202. Multiple protrusions 503 are fixed on the inner wall of the feed pipe 201. The feeding motor 501 drives the feeding plate 502 to rotate, so that the feeding plate 502 pushes and crushes the deoxidizer to prevent caking in the deoxidizer. At the same time, the feeding plate 502 squeezes the protrusions 503 and deforms. Then the feeding plate 502 separates from the protrusions 503, restores its deformation, and hits the inner wall of the feed pipe 201 to prevent the deoxidizer from remaining at the lower end of the feed pipe 201.

[0033] Symmetrical supports 601 are fixedly connected to both sides of the rotating shaft 302. A cone 602 is fixedly connected to the end of the support 601 away from the rotating shaft 302. The rotating shaft 302 drives the cone 602 to rotate through the support 601, so that the water flows faster from the large end to the small end of the cone 602, thereby improving the mixing efficiency of the deoxygenating agent.

[0034] Symmetrical connecting plates 701 are fixedly connected to both sides of the lower end of the rotating shaft 302. A scraper 702 is fixedly connected to the end of the connecting plate 701 away from the rotating shaft 302. The scraper 702 abuts against the bottom wall of the cylinder 101.

[0035] Working principle: During use, the deoxidizer is poured into the feed pipe 201 through the feed hopper. The feed motor 501 drives the feed plate 502 to rotate, causing the feed plate 502 to push and crush the deoxidizer, preventing clumping. The deoxidizer falls into the cylinder 101 through the filter plate 202. At the same time, the feed plate 502 squeezes and deforms the protrusion 503. Then, the feed plate 502 detaches from the protrusion 503, restores its deformation, and strikes the inner wall of the feed pipe 201, preventing deoxidizer residue from remaining at the lower end of the feed pipe 201. Then, the power motor 301 is started to drive the rotating shaft 302 to rotate. The rotating shaft 302 drives the sliding tube 401 to rotate, causing the stirring plate 402 to rotate around the sliding tube 401. When the sliding tube 401 rotates, it drives the sliding block 406 to slide against the sliding groove 404, causing the sliding tube 401 to slide up and down along the rotating shaft 302. This causes the stirring plate 402 to slide up and down near the end of the sliding tube 401, thereby causing the stirring plate 402 to rotate around the lower end of the connecting rod 405. This achieves the effect of stirring the plate 402 up and down, promoting the mixing of the deoxygenator and water in the cylinder 101, and making the deoxygenator evenly distributed in the water to reduce the oxygen content in the water. The rotating shaft 302 drives the cone 602 to rotate through the bracket 601, which increases the flow rate of water from the large end to the small end of the cone 602, thereby improving the mixing efficiency of the deoxygenator.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
