[0026] As a technical optimization scheme of the utility model, the feeding structure 4 includes the mounting seat 401, the mounting seat 401 is fixedly connected on the fixed plate 3, the feeding pipe 402 is installed on the mounting seat 401, the spiral shaft 403 is rotatably connected in the feeding pipe 402, the spiral blade 404 is fixedly connected on the spiral shaft 403, the second motor 405 is installed on the end of the feeding pipe 402, and the output shaft of the second motor 405 is fixedly connected with the spiral shaft 403;The lime in the hopper 407 flows into the feeding pipe 402 through the connecting frame 406, the second motor 405 is started, the second motor 405 drives the spiral blade 404 to rotate through the spiral shaft 403, the lime moves along the spiral blade 404 to the end of the feeding pipe 402, thereby realizing the quantitative delivery of the lime, since the section of the feeding pipe 402 is " L " shaped structure, the end of the feeding pipe 402 extends above the pool 1, the lime falls into the pool 1 evenly from the end of the feeding pipe 402, and the lime is preliminarily contacted with water and starts to react in the process of falling into the pool 1.

[0027] As a technical optimization scheme of the utility model, the top end of the feeding pipe 402 is fixedly connected with the connecting frame 406, the hopper 407 is installed on the connecting frame 406, the sliding plate 5 is slidably connected on the connecting frame 406, the section of the end of the sliding plate 5 is " T " shaped structure, the hydraulic rod 6 is installed on the connecting frame 406, the extension end of the hydraulic rod 6 is fixedly connected with the connecting rod 7, the connecting rod 7 is fixedly connected with the sliding plate 5, the section of the whole connecting rod 7 is " L " shaped structure, and the section of the end of the connecting rod 7 is " U " shaped structure;The lime is put into the hopper 407, when it is needed to increase the outflow of lime per unit time, the hydraulic rod 6 is started, the hydraulic rod 6 is elongated and drives the sliding plate 5 to slide to the outside of the connecting frame 406 through the connecting rod 7, thereby making the lime in the hopper 407 flow more into the connecting frame 406, so that the amount of lime delivered to the feeding pipe 402 and the pool 1 can be accurately adjusted through the sliding of the sliding plate 5, and the cooling water in the pool 1 reaches the best softening effect;The section of the end of the sliding plate 5 is " T " shaped structure, which can prevent the sliding plate 5 from sliding off the connecting frame 406, increases the stability of the sliding of the sliding plate 5, and the hopper 407 is convenient for storing lime.

[0029] In use, lime is first added to the hopper 407. When it is necessary to increase the lime output per unit time, the hydraulic rod 6 is activated. The hydraulic rod 6 extends and drives the sliding plate 5 to slide outwards from the connecting frame 406 via the connecting rod 7, thereby allowing more lime to flow into the connecting frame 406 from the hopper 407. Therefore, by sliding the sliding plate 5, the amount of lime delivered to the feeding pipe 402 and the water tank 1 can be precisely adjusted, thereby achieving the best softening effect for the cooling water in the water tank 1.

Since the cross-section of the feeding pipe 402 is "L" shaped, the end of the feeding pipe 402 extends above the water tank 1. Lime falls evenly into the water tank 1 from the end of the feeding pipe 402. During the process of falling into the water tank 1, the lime will initially come into contact with the water and begin to react. Then, the first motor 204 is started. The first motor 204 drives the lead screw 202 to rotate. The lead screw 202 drives the slider 203 to slide. The slider 203 drives the feeding structure 4 to move along the extension direction of the slide rail 201. The slide rail 201 is installed at one end close to the water inlet 8 of the water tank 1. Therefore, the lime put into the water tank 1 can flow towards the water outlet 9, so that the lime put into the water tank 1 is more evenly distributed, improving the softening effect of the cooling water, and making the maintenance and cleaning of the feeding structure 4 more convenient.
