Description

Technical Field

[0001] This utility model belongs to the field of agitator technology, specifically relating to a carbon steel surface coated with stainless steel agitator. Background Technology

[0002] In industrial production processes such as chemical, food, and pharmaceutical manufacturing, agitators are key equipment for achieving material mixing and reaction, and their performance plays a decisive role in production quality and efficiency. Especially towards the end of material concentration, the viscosity of the material increases significantly, making it prone to agglomeration and clumping, which poses a great challenge to the mixing operation.

[0003] Traditional carbon steel agitators exhibit numerous shortcomings when dealing with the agglomeration problem at the end of material concentration. Under conventional agitation methods, the agitator blades experience significant resistance when handling high-viscosity, agglomerated materials. Once this resistance exceeds the blades' tolerance, the blades and the agglomerated material are prone to expansion, deformation, or even breakage. This not only damages the agitator components but also drastically reduces agitation efficiency, severely extending the production cycle. Furthermore, traditional agitators lack specific solutions for effectively breaking up agglomerated materials, resulting in continuous, inefficient agitation that fails to meet the efficiency and quality requirements of industrial production. In addition, even if some agitators can barely handle agglomerated materials, prolonged high-load operation increases the risk of equipment failure, leading to higher maintenance costs. Frequent downtime for repairs disrupts production rhythms, causing economic losses for the company. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a carbon steel surface coated with stainless steel agitator, which solves the problem of low agitation efficiency and easy damage to the agitator caused by material clumping and agglomeration at the end of the concentration period.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carbon steel surface coated with stainless steel agitator, comprising a main shaft, an upper fixing component, a lower fixing component, and a crushing component fixedly installed on the lower side of the main shaft. The upper fixing component includes a first optical axis fixing seat with the same structure as the lower fixing component. A sleeve is connected to the closed end of the first optical axis fixing seat. An installation groove is provided on the side of the sleeve, and a pawl is provided in the installation groove. A paddle agitator is rotatably installed on the outside of the sleeve. The paddle agitator includes a sleeve, and a ratchet groove is provided on the inner wall of the sleeve. The ratchet groove engages the pawl in one direction. An agitator blade is installed on the outside of the sleeve. The crushing component includes a second optical axis fixing seat with the same structure as the lower fixing component. Crushing teeth are formed on the curved side of the closed end of the second optical axis fixing seat.

[0006] The beneficial effects of this utility model are as follows: when the main shaft rotates forward, it drives the paddle agitator to rotate and agitate the material through the ratchet mechanism; when the material clumps and agglomerates at the end of the concentration period, the main shaft reverses and does not transmit power to the paddle agitator, thus avoiding the paddle agitator from expanding, deforming or breaking with the agglomerated material. At the same time, the crushing component gradually crushes the agglomerated material during the rotation process, thereby improving the efficiency of the agitation production.

[0007] To ensure stable unidirectional engagement of the pawl with the ratchet groove;

[0008] As a further improvement to the above technical solution: a connecting shaft is rotatably inserted into one end of the pawl, the upper and lower ends of the connecting shaft are connected to the inner wall of the mounting groove, the pawl and the mounting groove are respectively connected to the two ends of the spring, and the spring is a V-shaped plate structure.

[0009] The beneficial effects of this improvement are: under the support of the spring, the pawl can rotate and unfold a stable one-way locking groove, thereby enabling the upper fixed part to drive the paddle agitator to rotate stably in one direction.

[0010] To further improve the stability of the transmission between the upper fixed component and the paddle agitator;

[0011] As a further improvement to the above technical solution: the number of the mounting slots is multiple, and they are equidistantly spaced around the axis of the sleeve.

[0012] The beneficial effects of this improvement are: multiple mounting slots and the ratchet pawls installed inside them can stably engage with the ratchet slots, ensuring the stability of the transmission between the upper fixing component and the paddle mixer.

[0013] To ensure the smooth rotation of the paddle mixer;

[0014] As a further improvement to the above technical solution: an end face bearing is fitted on the main shaft between the top end of the lower fixing member and the sleeve.

[0015] The beneficial effects of this improvement are: the end face bearing plays a role in rolling connection between the paddle agitator and the lower fixed part, reducing the resistance of the paddle agitator rotation.

[0016] To prevent material from entering the ratchet mechanism;

[0017] As a further improvement to the above technical solution: the closed end of the lower fixing member is inserted into the inner side of the sleeve, and a dynamic sealing ring is provided at the connection between the lower fixing member, the optical axis fixing seat and the ratchet groove.

[0018] The beneficial effects of this improvement are: the design of the dynamic sealing structure ensures the stability of the paddle agitator's rotation while effectively preventing materials from entering the ratchet structure and affecting the normal operation of the equipment.

[0019] In order to effectively break down clumps of material using a shredder;

[0020] As a further improvement to the above technical solution: the tooth end face of the pulverizing tooth is higher than the top of the pulverizing tooth.

[0021] The beneficial effects of this improvement are: the crushing teeth can crush the material on both sides of the optical axis fixing seat, the material between the crushing teeth and the bottom of the tank, and the material between the crushing teeth and the paddle agitator.

[0022] To effectively ensure the corrosion resistance of this agitator;

[0023] As a further improvement to the above technical solution: the surfaces of the main shaft and the agitator are coated with a stainless steel coating with a thickness of 0.1-0.5 mm.

[0024] The beneficial effects of this improvement are as follows: the stainless steel coating sprayed on the surface of the spindle and agitator can isolate the carbon steel spindle and agitator from the outside air, moisture and corrosive media, greatly improving the corrosion resistance of carbon steel and extending its service life.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Example 1:

[0034] like Figure 1As shown in Figure 5: A carbon steel agitator coated with stainless steel, comprising a main shaft 1. An upper fixing member 2, a lower fixing member 4, and a crushing component 5 are fixedly mounted on the lower side of the main shaft 1. The upper fixing member 2 includes a shaft fixing seat 21 with the same structure as the lower fixing member 4. A sleeve 22 is connected to the closed end of the shaft fixing seat 21. A mounting groove 23 is provided on the side of the sleeve 22, and a pawl 25 is provided inside the mounting groove 23. A paddle agitator 3 is rotatably mounted on the outside of the sleeve 22. The paddle agitator 3 includes a sleeve 31. A ratchet groove 33 is provided on the inner wall of the sleeve 31, and the ratchet groove 33 engages the pawl 25 in one direction. A stirring blade 32 is mounted on the outside of the sleeve 31. The crushing component 5 includes a shaft fixing seat 21 with the same structure as the lower fixing member 4. The second fixed seat 51 has crushing teeth 52 formed on the curved side of the closed end of the optical axis fixed seat 51. When the main shaft 1 rotates forward, it drives the paddle agitator 3 to rotate and agitate the material through the ratchet mechanism. When the material clumps and agglomerates at the end of the concentration period, the main shaft 1 reverses and does not transmit power to the paddle agitator 3, avoiding the expansion, deformation or breakage of the paddle agitator 3 and the agglomerated material. At the same time, the crushing component 5 gradually crushes the agglomerated material during rotation, improving the efficiency of the agitation production. One end of the pawl 25 is rotatably inserted with a connecting shaft 24. The upper and lower ends of the connecting shaft 24 are connected to the inner wall of the mounting groove 23. The pawl 25 and the mounting groove 23 are respectively connected to the two ends of the spring plate 26. The spring plate 26 has a V-shaped plate structure. Under the support of the spring plate 26, the pawl 25... A rotatable and stable one-way ratchet groove 33 allows the upper fixing member 2 to drive the paddle mixer 3 to rotate stably in one direction. Multiple mounting grooves 23 are equidistantly spaced around the axis of the sleeve 22. These mounting grooves 23 and their internally installed pawls 25 stably engage the ratchet groove 33, ensuring stable transmission between the upper fixing member 2 and the paddle mixer 3. An end-face bearing 6 is fitted onto the main shaft 1 between the top of the lower fixing member 4 and the sleeve 22. The end-face bearing 6 provides a rolling connection between the paddle mixer 3 and the lower fixing member 4, reducing the resistance to the rotation of the paddle mixer 3. The closed end of the lower fixing member 4 is inserted into the inner side of the sleeve 31. Dynamic sealing is provided at the connection points of the lower fixing member 4, the optical axis fixing seat 21, and the ratchet groove 33. The sealing ring and dynamic sealing structure design ensures the stability of the paddle agitator 3's rotation while effectively preventing materials from entering the ratchet structure and affecting the normal operation of the equipment. The tooth end face of the crushing tooth 52 is higher than the top of the crushing tooth 52. The crushing tooth 52 can crush the material around the optical shaft fixing seat 2 51, the material between the crushing tooth 52 and the bottom of the tank, and the material between the crushing tooth 52 and the paddle agitator 3. The surfaces of the main shaft 1 and the agitator 32 are coated with a stainless steel coating with a thickness of 0.1-0.5mm. The stainless steel coating on the surfaces of the main shaft 1 and the agitator 32 can isolate the carbon steel main shaft 1 and the agitator 32 from the outside air, moisture and corrosive media, greatly improving the corrosion resistance of the carbon steel and extending its service life.

[0035] The working principle of this technical solution is as follows: When it is necessary to perform conventional stirring of materials, the drive device is started to drive the main shaft 1 to rotate forward. When the main shaft 1 rotates, it drives the upper fixed part 2 to rotate synchronously. Since the pawl 25 in the mounting groove 23 on the side of the sleeve 22 in the upper fixed part 2 is stably engaged with the ratchet groove 33 on the inner wall of the sleeve 31 of the paddle mixer 3 under the support of the spring plate 26, the upper fixed part 2 can drive the paddle mixer 3 to rotate. During the rotation, the stirring blade 32 of the paddle mixer 3 stirs the materials in the tank to achieve the mixing, dispersion and other process operations of the materials. At this time, the end face bearing 6 mounted on the main shaft 1 between the top of the lower fixed part 4 and the sleeve 22 plays the role of rolling connection between the paddle mixer 3 and the lower fixed part 4, reducing the resistance of the paddle mixer 3 rotation and ensuring its smooth rotation.

[0036] When entering the final stage of concentration, the material is prone to agglomeration. At this time, the rotation direction of the main shaft 1 is changed to reverse. Due to the one-way meshing characteristic of the pawl 25 and the ratchet groove 33, the main shaft 1 does not transmit power to the paddle agitator 3 when it reverses, thus avoiding the expansion, deformation or breakage of the paddle agitator 3 and the agglomerated material. At the same time, the main shaft 1 drives the crushing component 5 to rotate. The crushing teeth 52 on the closed end curved surface of the optical shaft fixing seat 2 51 of the crushing component 5, with its special structural design, that is, the tooth end face is higher than the top of the crushing teeth 52, can effectively crush the material around the optical shaft fixing seat 2 51, the material between the crushing teeth 52 and the bottom of the tank, and the material between the crushing teeth 52 and the paddle agitator 3. As the main shaft 1 continues to rotate, the crushing component 5 gradually crushes the agglomerated material. After the material condition is improved, the main shaft 1 can be adjusted to rotate forward again to continue the stirring operation, thereby improving the efficiency of the stirring production.
