Description
Technical Field
[0001] This utility model relates to the field of scraped evaporator technology, specifically to a disc scraped evaporator. Background Technology
[0002] Scraped film evaporators are high-efficiency evaporation and distillation equipment that utilizes the centrifugal force of high-speed rotation to spread liquid materials into a uniform liquid film, aided by the application of a heating environment. They are widely used in chemical, pharmaceutical, food, and environmental protection fields. Traditional scraped film evaporators have a vertical structure, including a drive assembly, an evaporation cylinder, and a rotor. The evaporation cylinder is installed below the drive assembly and connected to the rotor, which is located inside the evaporation cylinder. The rotor structure includes a main shaft and scrapers fixed on the main shaft. Patent number CN201920782725.9 discloses a scraped film evaporator that enhances the evaporation effect by increasing the number of scrapers and adopting an asymmetrical scraper design, thereby increasing the disturbance effect of the scrapers on the liquid film surface. However, during the use of scraped film evaporators, impurities and dirt easily adhere to the inner wall of the evaporator, which can have a certain impact on the operation of the evaporator. Therefore, we propose a scraped film evaporator. Utility Model Content
[0003] To address the problems in the existing technology, this utility model provides a disc-type scraped evaporator.
[0004] The technical solution adopted by this utility model to solve its technical problem is a disc scraper evaporator, including an evaporator body. A vertical shaft for transmission is rotatably installed on the inner side of the evaporator body, and U-shaped plates are bolted to the outer circumference of the vertical shaft. There are multiple sets of U-shaped plates. The inner side of the U-shaped plates is provided with sliding holes for adjustment. There are two sets of sliding holes. A slider for adjustment is slidably installed on the inner side of the sliding holes. The outer wall surface of the slider is integrally constructed with straight bars for support. There are two sets of straight bars. The end of the straight bar away from the slider is bolted to a bracket for scraping material. The outer periphery of the card holder is fitted with a rubber strip that fits into the inner periphery of the evaporator body, and an internal hexagonal pin that is screwed into and connected to the rubber strip is screwed onto the outer wall surface of the card holder. A compression spring is assembled between the sliding hole and the slider.
[0005] By adopting the above technical solution, during the use of the disc scraper evaporator, the elastic biomimetic structure of the rubber strip can fit and abut against the inner circumference of the evaporator body, which facilitates scraping and cleaning of the inner circumference of the evaporator body. It can also adaptively adjust the pressure according to the viscosity of the material while avoiding damage caused by hard friction. The rubber strip can be disassembled and replaced simply by unscrewing the internal hexagonal pin on the outer circumference of the card holder, making the operation simple and convenient. During the use of the rubber strip, the other end of the card holder is connected to the slider in the sliding hole inside the U-shaped plate through multiple sets of straight bars. At the same time, the slider can slide and move in the sliding hole, and the compression spring can provide a certain elastic thrust for the slider. This allows the card holder and the rubber strip to cooperate more stably to fit and abut against the evaporator body, enabling it to operate more stably and further reducing the damage caused by the rubber strip to the evaporator body when it is scraped and cleaned.
[0006] Specifically, the outer wall surface of the U-shaped plate is fitted with a baffle that is connected to the straight bar by screws.
[0007] By adopting the above technical solution, the holes on the baffle and the straight strip are interlocked and slidably connected, which facilitates the sealing of the sliding holes on the U-shaped plate and enables the straight strip to slide more stably, thus providing auxiliary limiting support for the sliding of the card seat and the rubber strip.
[0008] Specifically, the multiple sets of U-shaped plates are integrally constructed.
[0009] By adopting the above technical solution, multiple sets of U-shaped plates are connected to each other to form a whole, which enables the U-shaped plates to more stably drive the mounting bracket and rubber strip to scrape and clean the inner circumference of the evaporator body.
[0010] Specifically, a guide plate is bolted to the outer periphery of the vertical shaft, and a spiral groove is formed on the outer periphery of the guide plate.
[0011] By adopting the above technical solution, the spiral groove on the outer periphery of the guide plate can extend the material residence path and enhance the turbulence effect, which facilitates the subsequent heating of the material.
[0012] Specifically, the outer circumference of the guide plate is integrally constructed with convex prisms, and there are multiple sets of convex prisms.
[0013] By adopting the above technical solution, the multiple sets of spirally distributed convex prisms on the outer periphery of the guide plate can be used in conjunction with the spiral groove, thereby further extending the material residence path.
[0014] Specifically, the inner circumferential surface of the sliding hole is integrally constructed with a protrusion that matches the slider, and there are multiple sets of protrusions.
[0015] By adopting the above technical solution, the protrusion on the inner circumference of the sliding hole can easily fit and slide with the groove on the outer circumference of the slider, which can improve the stability of the slider when it slides inside the sliding hole, and enable the slider to provide more stable limiting support for the card seat.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The technical solution of this application, through the design of vertical shaft, card seat, rubber strip and internal hexagon pin, can make the elastic biomimetic structure of the rubber strip fit and abut against the inner circumference of the evaporator body during the use of the disc scraper evaporator, thereby facilitating the scraping and cleaning of the inner circumference of the evaporator body. It can also adaptively adjust the pressure according to the viscosity of the material while avoiding damage caused by hard friction. Moreover, the rubber strip can be disassembled and replaced simply by unscrewing the internal hexagon pin on the outer circumference of the card seat, making the operation simple and convenient.
[0017] 2. The technical solution of this application, through the design of a U-shaped plate, sliding holes, sliders, compression springs, and straight bars, allows the other end of the card holder to be connected to the slider in the sliding holes inside the U-shaped plate through multiple sets of straight bars during the use of the rubber strip. At the same time, the slider can easily slide and move in the sliding holes, while the compression spring can provide a certain elastic thrust for the slider. This allows the card holder and the rubber strip to cooperate more stably and fit and abut against the evaporator body, enabling it to operate more stably and further reducing the damage caused by the rubber strip to the evaporator body when it is scraped and cleaned.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figure 1-4This utility model provides a technical solution: a disc scraper evaporator, including an evaporator body 1, a vertical shaft 2 for transmission rotatably mounted on the inner side of the evaporator body 1, and U-shaped plates 3 are bolted to the outer periphery of the vertical shaft 2, and there are multiple sets of U-shaped plates 3. The inner side of the U-shaped plates 3 is provided with sliding holes 4 for adjustment, and there are two sets of sliding holes 4. The sliding block 5 for adjustment is slidably mounted on the inner side of the sliding holes 4, and the outer wall surface of the sliding block 5 is integrally constructed with straight bars 6 for support, and there are two sets of straight bars 6. The end of the straight bar 6 away from the sliding block 5 is bolted to a clamping seat 8 for scraping material; the outer periphery of the clamping seat 8 is clamped with a rubber strip 9 that fits with the inner periphery of the evaporator body 1, and the outer wall surface of the clamping seat 8 is screwed with an internal hexagon pin 10 that is screwed to the rubber strip 9; a compression spring 11 is assembled between the sliding holes 4 and the sliding block 5.
[0022] When using the disc scraper evaporator, the elastic biomimetic structure of the rubber strip 9 can fit and abut against the inner circumference of the evaporator body 1, which makes it easy to scrape and clean the inner circumference of the evaporator body 1. It can also adaptively adjust the pressure according to the viscosity of the material while avoiding damage caused by hard friction. The rubber strip 9 can be disassembled and replaced simply by unscrewing the hexagonal pin 10 on the outer circumference of the card holder 8. The operation is simple and convenient. During the use of the rubber strip 9, the other end of the card holder 8 is connected to the slider 5 in the sliding hole 4 inside the U-shaped plate 3 through multiple sets of straight bars 6. At the same time, the slider 5 can slide and move in the sliding hole 4, and the compression spring 11 can provide a certain elastic thrust for the slider 5. This allows the card holder 8 and the rubber strip 9 to cooperate more stably and fit and abut against the evaporator body 1, enabling it to operate more stably and further reducing the damage caused by the rubber strip 9 when scraping and cleaning the evaporator body 1.
[0023] like Figure 2 and Figure 3 As shown, the outer wall surface of the U-shaped plate 3 is fitted with a baffle 7 that is connected to the straight bar 6 by screws.
[0024] When in use, the holes on the baffle 7 and the straight bar 6 are interlocked and slidably connected, which makes it easy to block the sliding holes 4 on the U-shaped plate 3 and make the straight bar 6 slide more stably, which facilitates the auxiliary limiting support for the sliding of the card seat 8 and the rubber strip 9.
[0025] like Figure 2 As shown, the multiple sets of U-shaped plates 3 are integrally constructed.
[0026] In use, multiple sets of U-shaped plates 3 are connected to each other to form a whole, which enables the U-shaped plates 3 to more stably drive the card holder 8 and the rubber strip 9 to scrape and clean the inner circumference of the evaporator body 1.
[0027] like Figure 4As shown, a guide plate 12 is bolted to the outer periphery of the vertical shaft 2, and a spiral groove 13 is provided on the outer periphery of the guide plate 12.
[0028] When in use, the spiral grooves 13 on the outer periphery of the guide plate 12 facilitate the extension of the material residence path and enhance the turbulence effect, which facilitates the subsequent heating of the material.
[0029] like Figure 4 As shown, the outer circumference of the guide plate 12 is integrally constructed with convex prisms 14, and there are multiple sets of convex prisms 14.
[0030] When in use, the multiple sets of spirally distributed convex prisms 14 on the outer periphery of the guide plate 12 can be used in conjunction with the spiral groove 13 to further extend the material residence path.
[0031] like Figure 3 As shown, the inner circumferential surface of the sliding hole 4 is integrally constructed with a protrusion 15 that matches the slider 5, and there are multiple sets of protrusions 15.
[0032] When in use, the protrusion 15 on the inner circumference of the sliding hole 4 can easily fit into and slide with the groove on the outer circumference of the slider 5, which can improve the stability of the slider 5 when it slides inside the sliding hole 4, and enable the slider 5 to provide more stable limiting support for the card seat 8.
[0033] The working principle and usage process of this utility model are as follows: During the use of the disc scraper evaporator, the drive motor rotates the vertical shaft 2 inside the evaporator body 1, facilitating centrifugal stirring of the material. Simultaneously, the elastic biomimetic rubber strip 9 engages with the inner circumference of the evaporator body 1, facilitating scraping and cleaning of the inner circumference. It also adaptively adjusts the pressure according to the viscosity of the material while avoiding damage caused by hard friction. The rubber strip 9 can be easily disassembled and replaced simply by unscrewing the internal hexagonal pin 10 on the outer circumference of the retainer 8, making operation simple and convenient. Furthermore, during the use of the rubber strip 9, the other end of the retainer 8 is connected to the slider 5 in the sliding hole 4 inside the U-shaped plate 3 via multiple sets of straight bars 6. Meanwhile, the slider 5 can slide and move within the sliding hole 4, while the compression spring 11 provides a certain elastic thrust to the slider 5. This allows the card holder 8 and the rubber strip 9 to cooperate more stably with each other and fit against the evaporator body 1, enabling more stable operation and further reducing the damage caused by the rubber strip 9 when scraping and cleaning the evaporator body 1. At the same time, the spiral groove 13 on the outer periphery of the guide plate 12 of the vertical shaft 2 can extend the material residence path and enhance the turbulence effect, facilitating subsequent heating of the material. Furthermore, the multiple sets of spirally distributed convex prisms 14 on the outer periphery of the guide plate 12 can be used in conjunction with the spiral groove 13, further extending the material residence path and enabling the scraper evaporator to operate more stably.
