Description

Technical Field

[0001] This utility model relates to the field of calcium hydroxide stirring technology, and in particular to a stirring device for producing highly active calcium hydroxide. Background Technology

[0002] Calcium hydroxide, as an important inorganic chemical raw material, has a wide range of applications in environmental protection, chemical industry, food, medicine and many other fields. Especially in the preparation of high-activity calcium hydroxide products, there are strict requirements for its performance indicators such as purity, particle size uniformity and reactivity. In the production of high-activity calcium hydroxide, the stirring process is the key step to ensure that calcium hydroxide and water are fully mixed and reacted, so as to obtain high-quality products.

[0003] A search revealed Chinese patent application number 202222097674.0, which discloses a stirring device for producing ultrapure calcium hydroxide. The device includes a cylindrical body with an end cap at the top. A rotating shaft is rotatably connected to the middle of the end cap. A second cutting tool is fixedly connected to the upper rear end of the rotating shaft, and a first cutting tool is fixedly connected to the upper front end of the rotating shaft. Rotating columns are provided at both the front and rear ends of the upper side of the middle of the rotating shaft. The rotating columns are all located on the upper side of a filter plate, and the rotating columns are fixedly connected to the rotating shaft. The bottom end of the rotating shaft penetrates the middle of the filter plate.

[0004] The stirring device for producing ultrapure calcium hydroxide in the above patent has the following shortcomings: after the larger quicklime is chopped up and filtered through a filter plate, some of the quicklime trapped by the filter will remain on the filter plate, which is inconvenient to clean and collect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stirring device for producing highly active calcium hydroxide.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stirring device for producing highly active calcium hydroxide includes a cylinder, an inlet valve fixed to the side wall of the cylinder, a bracket fixed to the top outer wall of the cylinder, a drive motor fixed to the top outer wall of the bracket, a stirring mechanism installed at the output end of the drive motor, connecting plates welded to the inner walls of both sides of the bracket, an electric telescopic rod fixed to the top outer wall of the connecting plate, a screening seat fixed to the output end of the electric telescopic rod by a pin, a screen fixed to the bottom of the screening seat, a notch I on the side wall of the screening seat, and a notch II on the top of the cylinder that cooperates with the notch I.

[0008] As a further embodiment of this utility model: the stirring mechanism includes stirring blades and stirring rods, the stirring rods are connected to and fixed to the output end of the drive motor via a coupling, and the stirring blades are welded to the outer wall of the stirring rods.

[0009] As a further improvement of this utility model: a top plate is fixed to the top of the screening seat, and a feed pipe is welded to the top of the top plate.

[0010] As a further embodiment of this utility model: a sleeve is fixed to the outer circumference of the stirring rod, and a sliding rod is movably connected to the bottom of the sleeve, and a contact plate is fixed to the top of the sliding rod, and a spring is installed between the contact plate and the sleeve, and an agitating plate is fixed to the bottom of the sliding rod.

[0011] As a further improvement of this utility model: a receiving box is fixed to the side wall of the cylinder, and a discharge pipe is welded to the bottom of the receiving box.

[0012] As a further improvement of this utility model, a discharge valve is fixed at the bottom of the cylinder.

[0013] As a further improvement of this utility model, a rib is fixed on the slide rod.

[0014] As a further improvement of this utility model, the screen has a conical structure.

[0015] Compared with the prior art, this utility model provides a stirring device for producing highly active calcium hydroxide, which has the following beneficial effects:

[0016] This application sieves the calcium hydroxide material at the bottom of the sieve seat before it enters the cylinder for stirring. This effectively removes large particles or unqualified particles from the material, ensuring that the calcium hydroxide material entering the cylinder for stirring has a uniform particle size. This improves the quality of the calcium hydroxide mixture after stirring, enabling it to better meet the production requirements of high-activity calcium hydroxide and enhancing the quality and performance stability of the final product.

[0017] The screening seat can be moved upward by an electric telescopic rod. When notch one and notch two are aligned, the conical screen can automatically slide off and discharge the calcium hydroxide material trapped by screening, avoiding the accumulation of material on the screen. This not only simplifies the cleaning process of the trapped material and reduces manual intervention and equipment downtime, but also ensures that the screening seat is always in a smooth screening state, so that the screening and mixing process can be carried out continuously and efficiently, greatly improving production efficiency and reducing equipment maintenance and production costs.

[0018] During the screening stage, the agitator plate rotates synchronously with the stirring rod, dynamically agitating the calcium hydroxide material in the screening seat. This breaks the static accumulation of material on the screen, allowing the material to be evenly dispersed and pass through the screen. This effectively avoids the problem of reduced screening speed and incomplete screening caused by excessive local material thickness, thus improving screening efficiency. During the discharge stage, the screening seat moves upward, causing the agitator plate to fit tightly against the screen. The agitator plate rotates at low speed, pushing the material trapped by the screen. The pushing force continuously and orderly pushes the material to notch one and notch two for discharge, preventing material from being stuck on the screen and achieving rapid and complete discharge of the trapped material.

[0019] Some parts are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0027] 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. Example 1

[0028] A stirring device for producing highly active calcium hydroxide, such as Figures 1 to 6As shown, the device includes a cylinder 1. A water inlet valve 3 is bolted to the side wall of the cylinder 1. A bracket 2 is bolted to the top outer wall of the cylinder 1. A drive motor 4 is bolted to the top outer wall of the bracket 2. A stirring mechanism is installed at the output end of the drive motor 4. Connecting plates 9 are welded to the inner walls on both sides of the bracket 2. An electric telescopic rod 8 is bolted to the top outer wall of the connecting plate 9. A screening seat 19 is pinned to the output end of the electric telescopic rod 8. A screen 21 is fixed to the bottom of the screening seat 19. A notch 1 is opened on the side wall of the screening seat 19. A notch 2 is opened on the top of the cylinder 1 to cooperate with the notch 1.

[0029] When it is necessary to stir the calcium hydroxide material, the calcium hydroxide material is first conveyed to the screening seat 19 by the feeding equipment such as the screw conveyor. The calcium hydroxide material is screened by the screen 21. After screening, the calcium hydroxide material falls to the bottom of the cylinder 1. At the same time, the water inlet valve 3 and the water pipe (not shown) are connected. When the water inlet valve 3 is opened, water is input into the cylinder 1 through the water pipe. When the drive motor 4 drives the stirring mechanism to rotate, the stirring mechanism is used to stir and mix the water and the calcium hydroxide material.

[0030] When it is necessary to process the calcium hydroxide material screened and retained on screen 21, the electric telescopic rod 8 drives the screening seat 19 to move upward along the inner circumference of the cylinder 1. When the bottom of notch one moves to be directly opposite the bottom of notch two, screen 21 has a conical structure, which allows the calcium hydroxide material screened and retained on screen 21 to slide along the upper surface of screen 21 and finally be discharged through notch one and notch two, thus avoiding the accumulation of calcium hydroxide material screened and retained on screen 21.

[0031] The stirring mechanism includes stirring blades 10 and stirring rods 12. The stirring rods 12 are connected to the output end of the drive motor 4 via a coupling, and the stirring blades 10 are welded to the outer wall of the stirring rods 12.

[0032] As the drive motor 4 drives the stirring rod 12 and stirring blade 10 to rotate, the water and calcium hydroxide materials are mixed and stirred.

[0033] The top of the screening seat 19 is fixed with a top plate 14 by screws, and a feed pipe 15 is welded to the top of the top plate 14.

[0034] When feeding calcium hydroxide material, the output end of the feeding equipment can be connected to the feed pipe 15 through a hose. After being conveyed, the calcium hydroxide material falls into the screening seat 19 for screening.

[0035] The bottom of the cylinder 1 is fixed with a discharge valve 11 by bolts.

[0036] After the water and calcium hydroxide are completely mixed, the mixture can be discharged by opening the drain valve 11.

[0037] The side wall of the cylinder 1 is fixed with a receiving box 6 by bolts, and a discharge pipe 7 is welded to the bottom of the receiving box 6.

[0038] The receiving box 6 can receive the calcium hydroxide material that is screened and retained, and the discharge pipe 7 can discharge the calcium hydroxide material that is screened and retained, making it easy to collect it using a collection box.

[0039] Working Principle: When it is necessary to stir calcium hydroxide material, firstly, connect the output end of the feeding equipment to the feed pipe 15 at the top of the screening base 19 through a hose to transport the calcium hydroxide material into the screening base 19. A conical screen 21 is fixed at the bottom of the screening base 19. After the material enters the screening base 19, it is screened by the screen 21. The screened calcium hydroxide material falls to the bottom of the cylinder 1. At the same time, connect the water inlet valve 3 to the water pipe and open the water inlet valve 3 to input water into the cylinder 1. Start the drive motor 4, which drives the stirring rod 12 to rotate through the coupling. The stirring rod 12 has stirring blades 10 welded to its outer wall. During the rotation of the stirring rod 12 and the stirring blades 10, the water and calcium hydroxide material in the cylinder 1 are mixed and stirred. When it is necessary to process the calcium hydroxide material screened and retained on screen 21, the electric telescopic rod 8 is activated. The electric telescopic rod 8 drives the screening seat 19 to move upward along the inner circumference of the cylinder 1. When the bottom of the notch 1 on the side wall of the screening seat 19 moves to be directly opposite the bottom of the notch 2 at the top of the cylinder 1, the calcium hydroxide material screened and retained by the screen 21 will slide along the upper surface of the screen 21 and eventually be discharged through notch 1 and notch 2. The discharged calcium hydroxide material screened and retained falls into the receiving box 6. The bottom of the receiving box 6 is welded with a discharge pipe 7. The calcium hydroxide material screened and retained can be discharged through the discharge pipe 7, which is convenient for collection by the collection box. After the water and calcium hydroxide material are fully mixed in the cylinder 1, the discharge valve 11 at the bottom of the cylinder 1 is opened to discharge the stirred mixture. Example 2

[0040] A stirring device for producing highly active calcium hydroxide, designed to improve the screening rate of calcium hydroxide materials, such as... Figures 1 to 6 As shown, this embodiment makes the following additions based on embodiment 1: the outer circumference of the stirring rod 12 is fixed with a sleeve 13 by screws, and a sliding rod 17 is slidably connected to the bottom of the sleeve 13. The top of the sliding rod 17 is fixed with a contact plate 16 by screws, and a spring 20 is installed between the contact plate 16 and the sleeve 13. The bottom of the sliding rod 17 is fixed with a stirring plate 18 by screws.

[0041] The sleeve 13 and the stirring rod 12 are fixedly connected so that when the drive motor 4 drives the stirring rod 12 to rotate, the sleeve 13, the slide rod 17 and the stirring plate 18 rotate synchronously. The slide rod 17 is fixed with ribs 5 to prevent relative rotation between the sleeve 13 and the slide rod 17. During the rotation, the stirring plate 18 agitates the calcium hydroxide material in the screening seat 19. In the initial state, a certain gap is maintained between the bottom of the stirring plate 18 and the screen 21, so as to avoid the stirring plate 18 and the screen 21 sticking together when agitating the calcium hydroxide material in the screening seat 19, which would cause the stirring plate 18 to rotate along the surface of the screen 21 for a long time and cause great wear. The stirring plate 18 agitates the calcium hydroxide material in the screening seat 19, thereby preventing the calcium hydroxide material from accumulating in one place on the screen 21.

[0042] When it is necessary to discharge the calcium hydroxide material that has been screened, the electric telescopic rod 8 drives the screening seat 19 to move upward. During the upward movement of the screening seat 19, the screen 21 gradually comes into contact with the bottom of the stirring plate 18. As the screen 21 continues to move upward, the spring 20 is stretched. During this process, the bottom of the stirring plate 18 and the screen 21 always remain in contact. When notch one and notch two are aligned, the drive motor 4 indirectly drives the stirring plate 18 to rotate at a lower speed. During the rotation, the stirring plate 18 moves the calcium hydroxide material that has been screened on the screen 21, thereby ensuring that the calcium hydroxide material that has been screened on the screen 21 is gradually discharged from notch one and notch two during the process of being moved.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
