Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically to a calcium hydroxide production equipment for fine screening and impurity removal. Background Technology

[0002] Calcium hydroxide, as an important chemical raw material, is widely used in construction, environmental protection, chemical industry, and food processing. In its production process, material screening and impurity removal are key steps, directly affecting the purity and quality of the product.

[0003] However, existing calcium hydroxide production equipment has many shortcomings in screening and impurity removal. Traditional screening equipment typically uses a single sieve structure, which makes it difficult to achieve fine classification of materials, resulting in low screening efficiency and insufficient accuracy. In addition, existing equipment often lacks effective impurity removal methods when processing materials containing metallic impurities or other foreign matter, failing to meet the production requirements of high-purity calcium hydroxide. Furthermore, some equipment is prone to material accumulation or blockage during operation, affecting the continuity and stability of production.

[0004] Therefore, developing a calcium hydroxide production equipment capable of efficient and precise screening, effective impurity removal, and continuous production has become a pressing technical challenge. This invention aims to provide a calcium hydroxide production equipment with high screening accuracy, excellent impurity removal, and stable and reliable operation through innovative structural design, to meet the diverse needs of actual production. Utility Model Content

[0005] This invention addresses the problems of low efficiency, complex operation, and difficulty in adapting to large-scale industrial production in existing calcium hydroxide production equipment during the screening and impurity removal processes. It provides a fine screening and impurity removal device for calcium hydroxide production. The device achieves effective separation and purification of calcium hydroxide raw materials through a combination of multi-stage screening and electromagnetic impurity removal.

[0006] This invention provides a fine screening and impurity removal equipment for calcium hydroxide production, including a main tank, a feed inlet, a waste outlet, an extension plate, a spring, a support, a motor, a conical hopper, a waste removal tank, and a final discharge hopper. The main tank is cylindrical, with a feed inlet at the top and a conical hopper connected to the bottom. A primary sieve plate and a fine sieve plate are sequentially arranged axially inside the main tank for grading and screening the material. Furthermore, a rotating rod penetrates the main tank and is driven by a motor. The rotating rod is equipped with a connecting disc and guide vanes to move the material within the main tank, thereby improving screening efficiency. Notably, a waste outlet is located on the side of the main tank, through which waste generated during the screening process is discharged via a pipe, preventing waste accumulation from affecting subsequent operations.

[0007] Furthermore, the extension plate extends outward from the bottom of the main tank, and a spring is installed beneath the extension plate. The spring, in conjunction with the support frame, enables a flexible connection between the main tank and the main tank. This flexible connection design allows the equipment to be fitted with a vibration motor as needed. The vibration of the motor assists the movement of materials on the screen plate, enhancing the screening effect. The support frame is fixed beneath the extension plate, supporting the entire equipment and ensuring its stability and safety during operation.

[0008] A conical hopper is located at the bottom of the main tank and is connected to it. The hopper guides the screened material into a removal tank. Further, the removal tank is connected below the conical hopper. An electromagnetic strip is installed inside the removal tank. This strip generates a magnetic field to attract metallic impurities in the material, thus achieving further removal. Specifically, an air inlet pipe is provided on the removal tank. This pipe introduces gas to regulate the pressure inside the tank or assist material flow. It can also remove impurities adhering to the surface of the electromagnetic strip when necessary, ensuring the continuity of the removal process.

[0009] The final discharge hopper is connected to the bottom of the impurity removal tank and is used to collect the finished calcium hydroxide product after screening and impurity removal. The design of the final discharge hopper facilitates the centralized collection and subsequent processing of the finished product, thereby improving overall production efficiency.

[0010] The technical solution of this utility model has the following technical points: First, a primary screen plate and a fine screen plate are set in the main tank, and combined with the connecting disc and guide blades on the rotating rod, the uniformity of material distribution and flowability on the screen plate are enhanced through mechanical movement, significantly improving the screening efficiency. Second, the main tank is flexibly connected to the support through springs, allowing the equipment to be equipped with a vibration motor, and the vibration of the vibration motor further enhances the screening effect. Third, an electromagnetic strip is set in the impurity removal tank and gas is introduced through the air inlet pipe, which can not only effectively adsorb metal impurities, but also remove the adhering substances on the surface of the electromagnetic strip through gas flow, ensuring the continuous and efficient impurity removal process. Finally, the design of the conical discharge hopper and the final discharge hopper optimizes the material flow path, reduces material residue, and improves the collection efficiency of the finished product.

[0011] The beneficial effects of this invention are as follows: by combining multi-stage screening within the main tank with electromagnetic impurity removal in the impurity removal tank, efficient separation and purification of calcium hydroxide raw materials are achieved. The equipment has a compact structure, clear connections between components, and is easy to operate, making it suitable for large-scale industrial production. In particular, the flexible connection design and the introduction of a vibrating motor enhance the adaptability of the equipment, while the cooperation between the electromagnetic strip and the air inlet pipe further improves the impurity removal effect. Overall, this invention significantly improves production efficiency and product quality, meeting the high-performance requirements of modern industry for calcium hydroxide production equipment.

[0017] 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.

[0018] This utility model relates to a calcium hydroxide production equipment for fine screening and impurity removal, and its specific implementation method is described in detail with reference to the accompanying drawings. Figures 1 to 4 As shown, the equipment includes a main tank 1, a feed inlet 2, a waste outlet 3, an extension plate 11, a spring 12, a support 13, a motor 41, a conical hopper 7, a waste removal tank 8, and a final discharge hopper 9. These components, through reasonable design and connection, form a complete production system for achieving efficient screening and impurity removal of calcium hydroxide raw materials.

[0019] The main tank 1 has a cylindrical structure with a feed inlet 2 at the top and a conical discharge hopper 7 at the bottom. The overall design is compact and functionally clear. Inside the main tank 1, a primary screen plate 5 and a fine screen plate 6 are arranged axially, working together to classify and screen the material. The primary screen plate 5 removes larger particles or impurities, while the fine screen plate 6 further separates smaller particles, ensuring the material meets the required particle size standard. A rotating rod 4 passes through the main tank 1 and is driven to rotate by a motor 41. A connecting disc 42 and guide vanes 43 are mounted on the rotating rod 4. The connecting disc 42 is fixed to the rotating rod 4, and the guide vanes 43 are spirally distributed, enabling the material to move within the main tank 1 as the rotating rod 4 rotates, thereby enhancing the uniformity and flowability of the material on the screen plates. This mechanical motion design significantly improves screening efficiency while avoiding material accumulation that leads to insufficient screening.

[0020] A waste outlet 3 is located on the side of the main tank 1, through which waste generated during the screening process is discharged via a pipe. The location of the waste outlet 3 is optimized to promptly remove large particles of impurities generated during screening, preventing waste accumulation from affecting subsequent operations. Furthermore, the main tank 1 utilizes a flexible connection to achieve vibration-assisted operation. Specifically, a spring 12 is installed below an extension plate 11 extending outward from the bottom of the main tank 1. The spring 12 cooperates with a bracket 13 fixed below the extension plate 11, forming a flexible connection between the main tank 1 and the bracket 13. This flexible connection design allows for the installation of a vibration motor on the main tank 1. The vibration generated by the motor is transmitted to the main tank 1, further enhancing the movement of materials on the screen plate and improving screening accuracy and efficiency. The bracket 13 serves as the supporting structure for the entire equipment, ensuring its stability and safety during operation.

[0021] The conical hopper 7 at the bottom of the main tank 1 optimizes the material flow path through its inclined design, reducing material residue. The screened material enters the impurity removal tank 8 through the conical hopper 7. The impurity removal tank 8 is connected below the conical hopper 7 and is used to further remove metallic impurities from the material. An electromagnetic strip 81 is installed inside the impurity removal tank 8. When energized, the electromagnetic strip 81 generates a magnetic field that adsorbs metallic impurities in the material, thus achieving efficient impurity removal. To ensure the continuity of the impurity removal process, an air inlet pipe 82 is installed on the impurity removal tank 8. The air inlet pipe 82 introduces gas to regulate the pressure inside the tank and assist material flow. When too many impurities are adsorbed on the surface of the electromagnetic strip 81, a high-speed airflow can be introduced through the air inlet pipe 82 to remove the impurities adhering to the surface of the electromagnetic strip 81, ensuring that the impurity removal effect is not affected.

[0022] The final discharge hopper 9 is connected to the bottom of the impurity removal tank 8 and is used to collect the finished calcium hydroxide product after screening and impurity removal. The design of the final discharge hopper 9 facilitates centralized collection and subsequent processing of the finished product, reduces manual operation, and improves overall production efficiency. In addition, the outlet position of the final discharge hopper 9 can be adjusted according to actual needs to adapt to different packaging or transportation requirements.

[0023] The working principle of this utility model is as follows:

[0024] S1, the calcium hydroxide raw material to be processed enters the main tank 1 through the feed inlet 2;

[0025] S2, inside the main tank 1, the motor 41 drives the rotating rod 4 to rotate, which drives the connecting plate 42 and the guide blade 43 to work, guiding the material to move inside the main tank 1;

[0026] S3, the material is screened through multiple stages of primary screen plate 5 and fine screen plate 6, and larger particle impurities are discharged through waste outlet 3.

[0027] S4, the screened material enters the impurity removal tank 8 through the conical feed hopper 7, and undergoes further impurity removal under the action of the electromagnetic strip 81;

[0028] S5 Finally, the finished calcium hydroxide product, after screening and impurity removal, is collected through the final discharge hopper 9.

[0029] In practical applications, this equipment can be widely used in the chemical industry, especially in large-scale calcium hydroxide production lines. For example, on a calcium hydroxide production line in a chemical plant, this equipment can process approximately 10 tons of raw material per day. The specific operating procedure is as follows: First, the raw material is fed into the feed inlet 2 through a conveyor device. The motor 41 is started, causing the rotating rod 4 to begin rotating, while the vibrating motor is activated to assist in screening. After multi-stage screening through the primary sieve plate 5 and the fine sieve plate 6, most impurities are effectively separated and discharged through the waste outlet 3. The screened material enters the conical discharge hopper 7 and then flows into the impurity removal tank 8. In the impurity removal tank 8, the electromagnetic strip 81 generates a strong magnetic field after being energized, adsorbing metallic impurities in the material. Every so often, a high-speed airflow is introduced through the air inlet pipe 82 to remove the deposits on the surface of the electromagnetic strip 81, ensuring that the impurity removal process is continuously efficient. Finally, the finished product is collected through the final discharge hopper 9 and directly bagged, completing the entire production process.

[0030] This invention achieves efficient separation and purification of calcium hydroxide raw materials by combining multi-stage screening within the main tank 1 with electromagnetic impurity removal in the impurity removal tank 8. The equipment has a compact structure, clear connections between components, and is easy to operate, making it suitable for large-scale industrial production. In particular, the flexible connection design and the introduction of a vibrating motor enhance the equipment's adaptability, while the cooperation between the electromagnetic strip 81 and the air inlet pipe 82 further improves the impurity removal effect. Overall, this invention significantly improves production efficiency and product quality, meeting the high-performance requirements of modern industry for calcium hydroxide production equipment.
