Description

Technical Field

[0001] This utility model belongs to the field of coagulant manufacturing technology, specifically relating to a mixing and feeding device for coagulant manufacturing. Background Technology

[0002] A setting accelerator is a substance used to accelerate the setting and hardening of materials. It is widely used in the construction and medical fields. In construction, setting accelerators are also known as concrete setting agents, which improve the workability, strength, and durability of concrete, thereby increasing the stability and reliability of concrete structures. In the medical field, setting accelerators are also known as hemostatic agents, which are drugs or substances that promote blood clotting. They are mainly used to accelerate the blood clotting process, ensuring rapid and complete coagulation, while ensuring that the components of the setting accelerator do not affect the experimental results of the specimen.

[0003] In the manufacturing process of accelerators, the mixing and feeding device is a key piece of equipment. It is responsible for mixing various raw materials in a certain proportion to ensure the quality and performance of the accelerator. However, due to the characteristics of the raw materials, especially powdered materials, they are prone to agglomeration when added in the correct proportions. This agglomeration not only makes the processing of the raw materials before they are added to the mixing equipment difficult, but may also further exacerbate the mixing difficulty after they enter the mixing equipment, because the agglomerated powder is not easily dispersed and mixed evenly. This phenomenon can directly affect the production efficiency and product quality of the accelerator. Utility Model Content

This agglomeration not only makes the processing of raw materials before they are fed into the mixing equipment difficult, but may also further exacerbate the mixing difficulty after they enter the mixing equipment, because the agglomerated powder is not easily dispersed and mixed evenly. This phenomenon may directly affect the production efficiency and product quality of the coagulant.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and feeding device for manufacturing a coagulant, comprising a base and a mixing chamber.

[0020] 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.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a mixing and feeding device for manufacturing a coagulant, comprising a base 1 and a mixing chamber 2, wherein a stirring motor 3 is installed at the top of the mixing chamber 2, and feed pipes 4 are connected to the top of the mixing chamber 2 and on both sides of the stirring motor 3, a discharge pipe 5 is connected to one side of the bottom of the mixing chamber 2, a control valve 6 is connected to the surface of the discharge pipe 5, and a discharge pump 7 is connected to the end of the discharge pipe 5, a stirring rod 8 and a filter screen 10 are assembled inside the mixing chamber 2, a scraper 9 is connected to the surface of the stirring rod 8 and at the top of the filter screen 10, a support block 11 is connected to the inner wall of the mixing chamber 2, and a connecting plate 14 is installed at the top of the support block 11.

[0023] In this embodiment, the raw materials for the coagulant are first fed through the feed pipe 4 and then fall onto the surface of the filter screen 10. Next, the stirring motor 3 is powered on and begins operation, its output shaft driving the stirring rod 8 and scraper 9 to rotate. During this process, the scraper 9 pushes the raw materials along the mesh opening of the filter screen 10, allowing them to fall smoothly. The stirring rod 8 then stirs the fallen raw materials. This series of actions effectively reduces the adhesion of the raw materials, creating favorable conditions for the subsequent uniform mixing of the raw materials.

[0024] In addition, the mixed raw materials are sent to the outside through the discharge pipe 5 by opening the control valve 6 and then starting the discharge pump 7.

[0025] Example 2

[0026] Please see Figure 1-4 The support block 11 is equipped with a spring 12, and a support rod 13 is installed at the end of the spring 12. The bottom end of the connecting plate 14 is connected to the support rod 13, and the connecting plate 14 and the spring 12 form an elastic telescopic connection through the support rod 13.

[0027] In a preferred embodiment: the filter screen 10 is movably connected to the internal cavity of the mixing chamber 2 and is sized to fit the cavity; the bottom end of the filter screen 10 is connected to the top end of the connecting plate 14.

[0028] In a preferred embodiment: the top end of the stirring rod 8 is connected to the output shaft of the stirring motor 3, and the scraper 9 is rotatably connected to the inside of the mixing chamber 2 via the stirring rod 8.

[0029] In this embodiment, as described in Embodiment 1, when the raw material is fed from the feed pipe 4 and falls onto the surface of the filter screen 10, it will generate a certain amount of inertia, causing the filter screen 10 to descend due to the force. At this time, the support rod 13 will compress the spring 12 to cause it to contract. This ingenious design gives the filter screen 10 good cushioning performance, effectively preventing the filter screen 10 from being directly subjected to inertial impact, thereby significantly improving the durability of the filter screen 10 and extending its service life.

[0030] Example 3

[0031] Please see Figure 1-4 A fixing block 15 is connected to the top surface of the bottom end of the base 1. A bidirectional threaded rod 16 is assembled inside the fixing block 15. A bearing 17 is installed at one end of the bidirectional threaded rod 16. A clamping rod 18 is threadedly connected to the surface of the bidirectional threaded rod 16.

[0032] In a preferred embodiment, the opposing threads on the surface of the bidirectional threaded rod 16 are symmetrical, and the bidirectional threaded rod 16 is rotatably connected to the inside of the fixed block 15 via the bearing 17.

[0033] In a preferred embodiment, the clamping rod 18 forms a reciprocating threaded motion with the fixing block 15 via the bidirectional threaded rod 16.

[0034] In this embodiment, as described in Embodiment 1, centrifugal force is generated during the operation of the stirring rod 8. At this time, the bidirectional threaded rod 16 begins to rotate, smoothly rotating along the inner ring of the bearing 17 inside the fixing block 15. As the bidirectional threaded rod 16 rotates, its surface with opposite threads causes the clamping rods 18 to move closer together. These gradually approaching clamping rods 18 then press tightly against the periphery of the mixing chamber 2, achieving clamping and fixing of the outer wall of the mixing chamber 2. This innovative design significantly enhances the overall stability of the equipment during operation, ensuring that the mixing process can proceed smoothly and without error.

[0035] In summary, as described in Embodiments 1 to 3, this invention utilizes the filter screen 10 and scraper 9 to reduce material adhesion and promote uniform mixing. Simultaneously, the buffer spring 12 at the bottom of the filter screen 10 enhances durability, while the clamping rod 18 stabilizes the mixing chamber 2, preventing shaking during stirring and ensuring a stable mixing process.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
