[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1 - Fig.11The slurry preparation tank for desulfurization agent production with adjustable concentration shown in the figure comprises a mixing tank 1, a top bin 2 is arranged on the top of the mixing tank 1, and feeding pipes 3 are connected to the two sides of the top bin 2. A filter mechanism is arranged inside the top bin 2, and the feeding pipe 3 is located above the filter mechanism. The filter mechanism comprises a dispersion mechanism 5 and a mixing mechanism 6. The dispersion mechanism 5 is located above the mixing mechanism 6. The dispersion mechanism 5 is used for dispersing limestone and dolomite, and the mixing mechanism 6 is used for preliminarily mixing limestone and dolomite. The mixing mechanism 6 comprises a mixing barrel, a mixing barrel, and a mixing barrel. A first opening 22 and a second opening 23 are symmetrically provided at the bottom of the barrel, and an inner sleeve 14 is provided above the center of the mixing barrel. The inner sleeve 14 can be moved up and down to control the opening and closing of the first opening 22 and the second opening 23. By providing a dispersion mechanism 5, the limestone and dolomite can be evenly dispersed, and the even distribution of the limestone and dolomite can be ensured. Under the action of the mixing mechanism 6, the limestone and dolomite can be mixed, so that the mixing tank 1 can process the limestone and dolomite quickly and evenly, thereby improving work efficiency.

[0018] A stepper motor 4 is arranged on the top of the top bin 2, and a connecting rod 7 is connected to the output end of the stepper motor 4. The connecting rod 7 is inside the top bin 2. The dispersing mechanism 5 includes a material distribution plate 8. The end of the material distribution plate 8 is fixedly connected to the inner wall of the top bin 2. The surface of the connecting rod 7 movably passes through the material distribution plate 8. A filter screen 9 is arranged on the top surface of the material distribution plate 8. The horizontal height of the middle part of the filter screen 9 is higher than the horizontal height of the end part of the filter screen 9. Four scrapers 10 are evenly arranged on the upper surface of the filter screen 9. A connecting frame 11 is installed at one end of the scraper 10 close to the middle part of the filter screen 9. A fixing block 12 is fixedly installed at the other end of the connecting frame 11. The other end of the fixed block 12 is fixedly installed on the surface of the connecting rod 7 by bolts. The bottom surface of the scraper 10 cooperates with the surface of the filter screen 9. The connecting rod 7 is driven to rotate by the stepper motor 4. The connecting rod 7 can drive the four scrapers 10 to rotate on the surface of the filter screen 9. When the limestone and dolomite fall to the surface of the filter screen 9, the limestone and dolomite will pass through the grid on the surface of the filter screen 9. At the same time, the rotation of the scraper 10 can push the limestone and dolomite, so that the stuck limestone and dolomite roll on the surface of the filter screen 9, thereby breaking the adhesion between the limestone and dolomite and separating them.

[0019] A rectangular rod 13 is fixedly installed at the bottom of the connecting rod 7, and an inner sleeve 14 is sleeved on the surface of the rectangular rod 13. The inner sleeve 14 is directly below the distribution plate 8, and an outer sleeve 16 is installed at the middle end of the bottom of the distribution plate 8 by bolts. The outer sleeve 16 is sleeved on the outside of the inner sleeve 14, and a columnar slider 15 is fixedly provided on the surface of the inner sleeve 14 near the top. The inner wall of the outer sleeve 16 is symmetrically provided with two arc-shaped grooves 17, and the ends of the two arc-shaped grooves 17 are fixedly connected. The columnar slider 15 is slidably installed inside the arc-shaped grooves 17. When the connecting rod 7 rotates, the rectangular rod 13 will drive the inner sleeve 14 to rotate, and at the same time, the columnar slider 15 on the surface of the inner sleeve 14 can slide inside the two arc-shaped grooves 17. Since the horizontal heights of the two ends of the arc-shaped grooves 17 are inconsistent, the inner sleeve 14 will also reciprocate upward and downward while the inner sleeve 14 rotates.

[0020] A positioning cylinder 18 is fixedly installed at the bottom of the inner sleeve 14, and a polished rod 19 is fixedly installed inside the positioning cylinder 18. The mixing barrel is arranged directly below the outer sleeve 16, and the surface of the polished rod 19 is installed inside the mixing barrel. A stirring blade 20 is installed on the surface of the polished rod 19 inside the mixing barrel, which is fixedly connected to the polished rod 19 through the positioning cylinder 18. The polished rod 19 will move synchronously with the inner sleeve 14, so that the stirring blade 20 on the surface of the polished rod 19 can stir the limestone and dolomite in the mixing barrel, so that the limestone and dolomite can be fully mixed together.

[0021] A plate receiving groove is provided at the middle end of the bottom of the mixing barrel, a first sealing plate 24 is slidably provided inside the first opening 22, and a second sealing plate 25 is slidably provided inside the second opening 23. The plate receiving groove cooperates with the first sealing plate 24. When the first sealing plate 24 slides to the inside of the plate receiving groove, the first opening 22 is in an open state, and the limestone and dolomite in the mixing barrel can enter the mixing tank 1 from the first opening 22. When the second sealing plate 25 slides to the outside of the mixing barrel, the second opening 23 is in an open state, and the limestone and dolomite in the mixing barrel can enter the mixing tank 1 from the second opening 23.

[0022] A chassis 21 is fixedly installed at the bottom of the bare rod 19, and a T-shaped slide groove 26 is opened on the bottom surface of the chassis 21. Two T-shaped sliders 29 are symmetrically arranged inside the T-shaped slide groove 26. The T-shaped slider 29 is slidably arranged in the T-shaped slide groove 26, and a first positioning frame 28 is fixedly installed at the bottom of the T-shaped slider 29. A second positioning frame 31 is installed in the middle of the same side of the first sealing plate 24 and the second sealing plate 25. A connecting rod 27 is connected between the first positioning frame 28 and the second positioning frame 31 through a rotating shaft. Since the T-shaped slider 29 is slidably installed in the T-shaped slide groove 26, the chassis 21 can push and pull the connecting rod 27 while moving up and down, thereby being able to control the position of the first sealing plate 24 and the second sealing plate 25.

[0023] Inclined surfaces 30 are installed inside the mixing barrel and on the sides of the first opening 22 and the second opening 23. Limestone and dolomite can slide from the inclined surfaces 30 to the first opening 22 and the second opening 23, which facilitates the discharge of limestone and dolomite and avoids residual limestone and dolomite in the mixing barrel.

[0024] Working principle: first, the staff transports limestone and dolomite into the top bin 2 through the feed pipe 3. The limestone and dolomite will fall to the surface of the filter screen 9 under the action of gravity, and then the connecting rod 7 is driven to rotate by the stepper motor 4. The connecting rod 7 can drive the four scrapers 10 to rotate on the surface of the filter screen 9, so that the limestone and dolomite pass through the grid on the surface of the filter screen 9. Then, while the connecting rod 7 rotates, the rectangular rod 13 will drive the inner sleeve 14 to rotate, and at the same time, the columnar slider 15 on the surface of the inner sleeve 14 can slide inside the two arc-shaped slide grooves 17. Since the horizontal heights of the two ends of the arc-shaped slide grooves 17 are inconsistent, while the inner sleeve 14 rotates, the inner sleeve 14 will also reciprocate upward and downward, so that the polished rod 19 will also rotate inside the mixing barrel and reciprocate up and down, and the stirring blades 20 on the surface of the polished rod 19 can stir the limestone and dolomite in the mixing barrel, so that the limestone and dolomite can be fully mixed together. Finally, when the polished rod 19 rotates, the mixing blades 20 on the surface of the polished rod 19 can stir the limestone and dolomite in the mixing barrel, so that the limestone and dolomite can be fully mixed together. When the rod 19 moves upward, the chassis 21 moves upward. Under the action of the connecting rod 27, when the first sealing plate 24 can slide into the plate receiving groove, the first opening 22 is in an open state, and the limestone and dolomite in the mixing barrel can enter the mixing tank 1 from the first opening 22, and the second sealing plate 25 will slide into the second opening 23 to block the second opening 23. When the bare rod 19 moves downward, the chassis 21 moves downward, and the second sealing plate 25 will slide to the outside of the mixing barrel, and the second opening 23 is in an open state. The limestone and dolomite in the mixing barrel can enter the mixing tank 1 from the second opening 23, and the first sealing plate 24 will slide into the first opening 22 to block the first opening 22. The first opening 22 and the second opening 23 can be opened in turn to transport the limestone and dolomite in the mixing barrel. Each batch of limestone and dolomite entering can contact and blend more fully in a limited mixing space. Finally, the limestone and dolomite will be mixed with water to form a slurry.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
