Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mixing device for preventing the formation of a skin on the surface of an emulsion after hot discharge. Background Technology

[0002] In emulsion production, after hot discharge, the raw material often needs to be allowed to settle briefly in the raw material tank to collect residual material. Traditional mixing devices only focus on mixing the material inside the tank, neglecting the adhesion problem at the seal between the cover and the tank. When residual emulsion comes into contact with air at high temperatures, it easily forms a skin layer on the surface of the liquid, leading to decreased product uniformity and increased impurities. Although existing technologies reduce air contact by adding a lid, the material adhering to the edge of the seal cannot be reached by the mixing components and will still solidify into a skin, not only contaminating subsequent batches but also increasing manual cleaning costs and downtime. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem that in the prior art, the material adhering to the edge of the sealing ring will still solidify and form a skin because it cannot be touched by the stirring component, which not only contaminates subsequent batches, but also increases the cost of manual cleaning and downtime, a stirring device is provided to prevent the surface of the emulsion from forming a skin after hot discharge.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a stirring device to prevent the surface of emulsion from forming a skin after hot discharge, including a cover plate, a stirring mechanism, and a scraping mechanism. The cover plate is arranged on the material tank, and a sealing ring is formed by the protrusion of the bottom of the cover plate. The stirring mechanism and the scraping mechanism are arranged on the cover plate. The stirring mechanism is used to stir the material, and the scraping mechanism is used to scrape off the material adhering to the sealing ring. The scraping mechanism includes a scraping motor, a rotating seat, an inner scraping plate, and a bottom scraping plate. The scraping motor is fixedly connected to the top surface of the cover plate, and the output of the scraping motor is... The end is connected to the rotating seat via a drive. The scraper motor provides power for the rotation of the rotating seat. The rotating seat is rotatably arranged on the stirring mechanism. One side of the inner scraper is fixedly connected to the rotating seat, and the other side contacts the inner wall of the sealing ring. The bottom scraper is elastically connected to the inner scraper and contacts the bottom of the sealing ring. Through the dual-stage scraping of the inner scraper and the bottom scraper, the material adhering to the inner wall and bottom of the sealing ring is thoroughly removed. At the same time, the waiting time for the material to fall is reduced, thereby avoiding the exposure and crusting of residual emulsion. The stirring device can also be used in the next material tank.

[0005] To address the issues of space occupation and interference with stirring caused by independent scraping mechanisms, a stirring mechanism is further included, comprising a stirring motor, a stirring shaft, and stirring blades. The stirring motor is fixedly connected to the top surface of the cover plate, the output end of the stirring motor is drivenly connected to the stirring shaft, the stirring blades are arranged on the stirring shaft and located below the cover plate, and the rotating seat is rotatably connected to the stirring shaft.

[0006] To address the issue of incomplete scraping caused by scraper wear or sealing ring deformation, the system further includes a connecting cavity formed by a recess in the inner scraper plate and a connecting rod formed by a protrusion in the bottom scraper plate. The connecting rod and the inner scraper plate are slidably connected. A limit block is installed on the connecting rod, which is located inside the connecting cavity. An elastic element is sleeved on the connecting rod, located inside the connecting cavity, with one end of the elastic element abutting against the inner scraper plate and the other end abutting against the limit block.

[0007] To address the issue of damage caused by the bottom scraper plate colliding with the inner scraper plate when tilted, a further improvement is made to include a protective plate protruding from one end of the bottom scraper plate near the inner scraper plate, and a receiving groove on the inner scraper plate for accommodating the protective plate, with the protective plate slidably arranged within the receiving groove.

[0008] To solve the problem of jamming when the bottom scraper cuts into the material barrel, the bottom scraper is further provided with a first guide angle at the corner near the inner wall of the material barrel.

[0009] To address the issue of the sealing ring getting stuck when it enters the material barrel, a second guide angle is further included on the corner of the bottom of the sealing ring near the inner wall of the material barrel.

[0010] To address the issue of delayed material discharge due to manual temperature measurement, which exacerbates the risk of crust formation, a thermometer is further incorporated into the cover plate.

[0011] The beneficial effects of this utility model are: the stirring device provided by this utility model to prevent the surface of emulsion from forming a skin after hot discharge, through the double scraping of the inner scraper and the bottom scraper, thoroughly removes the material adhering to the inner wall and bottom of the sealing ring, while reducing the waiting time for the material to fall, thereby avoiding the exposure and skin formation of residual emulsion, and the stirring device can also be applied to the next material tank.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] like Figure 1 This is a schematic diagram of the structure of this utility model, a stirring device for preventing skin formation on the surface of emulsion after hot discharge, including a cover plate 1, a stirring mechanism 2, and a scraping mechanism 3, as shown. Figure 2 , 3 As shown, a cover plate 1 is arranged on the material bucket. A sealing ring 11 protrudes from the bottom of the cover plate 1. A stirring mechanism 2 and a scraping mechanism 3 are arranged on the cover plate 1. The stirring mechanism 2 is used to stir the material, and the scraping mechanism 3 is used to scrape off the material adhering to the sealing ring 11. The scraping mechanism 3 includes a scraping motor 31, a rotating seat 32, an inner scraping plate 33, and a bottom scraping plate 34. The scraping motor 31 is fixedly connected to the top surface of the cover plate 1. The output end of the scraping motor 31 is drivenly connected to the rotating seat 32. The scraping motor 31 provides power for the rotation of the rotating seat 32. The rotating seat 32 is rotatably arranged on the stirring mechanism 2. One side of plate 33 is fixedly connected to the rotating seat 32, and the other side contacts the inner wall of the sealing ring 11. The bottom scraper plate 34 and the inner scraper plate 33 are elastically connected. The bottom scraper plate 34 contacts the bottom of the sealing ring 11. Through the dual-stage scraping of the inner scraper plate 33 and the bottom scraper plate 34, the material adhering to the inner wall and bottom of the sealing ring 11 is thoroughly removed. At the same time, the waiting time for the material to fall is reduced, thereby avoiding the exposure and skin formation of residual emulsion. The stirring device can also be applied to the next material tank. The bottom scraper plate 34 and the inner scraper plate 33 adopt an elastic connection design to compensate for installation errors and wear, ensuring that the bottom scraper plate 34 always fits the sealing surface.

[0020] like Figure 2 As shown, the stirring mechanism 2 includes a stirring motor 21, a stirring shaft 22, and a stirring blade 23. The stirring motor 21 is fixedly connected to the top surface of the cover plate 1. The output end of the stirring motor 21 is connected to the stirring shaft 22. The stirring blade 23 is arranged on the stirring shaft 22 and is located below the cover plate 1. The rotating seat 32 is rotatably connected to the stirring shaft 22.

[0021] like Figure 2 ,3 As shown, a connecting cavity 331 is recessed on the inner scraper plate 33, and a connecting rod 341 is protruding on the bottom scraper plate 34. The connecting rod 341 and the inner scraper plate 33 are slidably connected. A limiting block 342 is installed on the connecting rod 341 and is located inside the connecting cavity 331. An elastic element 343 is sleeved on the connecting rod 341 and is located inside the connecting cavity 331. One end of the elastic element 343 abuts against the inner scraper plate 33, and the other end abuts against the limiting block 342. The elastic element 343 is a spring. The elastic element 343 pushes the bottom scraper plate 34 to adaptively press against the inner wall of the material barrel and compensate for gap changes.

[0022] like Figure 2 , 3 As shown, a protective plate 344 protrudes from one end of the bottom scraper plate 34 near the inner scraper plate 33. The inner scraper plate 33 has a receiving groove 332 for accommodating the protective plate 344. The protective plate 344 is slidably arranged in the receiving groove 332. The protective plate 344 is used to prevent material from splashing into the space between the inner scraper plate 33 and the bottom scraper plate 34.

[0023] like Figure 1 , 2 As shown in Figure 3, the bottom scraper plate 34 has a first guide angle 345 at the corner near the inner wall of the material barrel, and the bottom sealing ring 11 has a second guide angle 111 at the corner near the inner wall of the material barrel. The first guide angle 345 and the second guide angle 111 form a double guide slope, which can guide the stirring device to be installed in the material barrel and prevent the scraper mechanism 3 from getting stuck in the sealing gap when it rotates.

[0024] like Figure 1 , 2 As shown, the cover plate 1 has a thermometer 12. The integrated thermometer monitors the temperature inside the barrel in real time, which facilitates the control of the discharge timing and reduces the risk of thermal aging of heat-sensitive emulsions.

[0025] Working process: The stirring motor 21 drives the stirring shaft 22 to drive the blades 23 to mix the emulsion in the tank; the scraper motor 31 drives the rotating seat 32 to rotate, which drives the inner scraper 33 to scrape along the inner wall of the sealing ring 11; the bottom scraper 34 scrapes against the bottom of the sealing ring 11 under the pressure of the elastic element 343, pushing the adhered material back into the tank.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
