Description

Technical Field

[0001] This utility model relates to the technical field of scraped evaporation equipment, specifically a novel scraped evaporator. Background Technology

[0002] A scraped-plate evaporator is a highly efficient evaporation device that enhances heat transfer through rotating scrapers to achieve rapid evaporation and concentration of materials. The main body consists of a heating jacket, rotating scrapers, and a separation chamber. Material enters from the top, and the rotating scrapers scrape it into a uniform thin film on the heating tube wall. Heating through the jacket causes rapid evaporation. The vapor and liquid are separated in the separation chamber and discharged separately. It is suitable for processing heat-sensitive and high-viscosity materials, offering high heat transfer efficiency, a thin film thickness, and a heat transfer coefficient several times that of traditional evaporators.

[0003] An investigation revealed a novel scraper evaporator (publication number: CN223144148U) disclosed in a utility model patent. The evaporator includes an evaporator body, a servo motor fixedly mounted on the top of the evaporator body, a connecting rod fixedly connected to the output end of the servo motor, and an adjustment component at the bottom of the connecting rod. Movable scrapers are mounted on the four sides of the adjustment component. The adjustment component includes a four-claw base, an electric telescopic rod mounted on the top of the four-claw base, a connecting plate fixedly connected to the top of the electric telescopic rod, and a connecting rod rotatably connected to the bottom of the connecting rod at the top of the four-claw base via a rotating shaft. An L-shaped plate is rotatably connected to the end of the connecting rod away from the four-claw base via a rotating shaft, and the lower part of the L-shaped plate is slidably connected to the top of the connecting plate. This design, with its evaporator body, servo motor, connecting rod, adjustment component, and movable scrapers, allows for rapid adjustment of the distance between the movable scrapers and the inner wall of the evaporator shell, achieving an adjustment effect suitable for different types of materials.

[0004] While the aforementioned patent utilizes components such as servo motors, movable scrapers, and adjustment mechanisms, and the adjustment mechanism allows for adjustment of the scraping diameter by multiple L-shaped plates during evaporator operation to accommodate different materials, long-term use can be challenging. The high-speed rotation of the shaft drives the scrapers rapidly, and the adjustment mechanism uses an electric telescopic rod to move four movable scrapers. However, prolonged high-speed rotation can damage the electric telescopic rod, and when seal aging occurs, the electric telescopic rod may short-circuit and fail, significantly hindering the long-term use of the evaporator. Therefore, this invention provides a novel scraper evaporator to address these problems. Utility Model Content

[0005] To address the above technical problems, this utility model provides a novel scraped evaporator.

[0006] To solve the above-mentioned technical problems, the present invention provides a novel scraped evaporator, comprising an evaporator body and an adjustment assembly, wherein the adjustment assembly includes a top cover installed on the inner wall of the evaporator body, and a drive motor is installed inside the top cover.

[0007] The adjusting assembly further includes a mounting ring, an adjusting sleeve mounted on the inner wall of the mounting ring, a scraper slidably connected to the inner wall of the adjusting sleeve, a rotating sleeve rotatably sleeved at the inner top end of the adjusting sleeve, a sliding rod slidably connected to the inner wall of the rotating sleeve, an adjusting disc fixedly sleeved on the outer wall of the sliding rod, an adjusting screw threadedly connected to the inner wall of the adjusting disc, the adjusting screw rotatably sleeved at the inner top end of the mounting ring, and a feeding assembly provided at the upper top end of the top cover.

[0008] Furthermore, the output end of the drive motor is fixedly connected to the inner top end of the mounting ring via a coupling sleeve, and a ceramic scraper is installed on the outer wall of the scraper plate.

[0009] Furthermore, the feeding assembly includes a feeding bin fixedly connected to the top of the top cover, a servo motor is installed at the top of the feeding bin, and an auger blade is installed at the output end of the servo motor.

[0010] Furthermore, a heater is installed on the outer wall of the feeding hopper, a monitoring instrument is installed on the top of the heater, a feeding pipe is fixedly connected to the outer wall of the feeding hopper, and a flange is fixedly connected to the top of the feeding pipe.

[0011] Furthermore, a first heating jacket and a second heating jacket are respectively installed on the outer wall of the evaporator body. The second heating jacket is located at the lower end of the first heating jacket. The outer walls of both the first heating jacket and the second heating jacket are coated with an anti-rust coating.

[0012] Furthermore, a support base is fixedly connected to the lower bottom end of the evaporator body, and there are multiple support bases.

[0013] Furthermore, a hook is fixedly connected to the top end of the top cover, and the hook is symmetrically arranged along the center of the evaporator body.

[0014] This utility model has the following advantages compared with the prior art:

[0015] This invention, through the setting of the adjustment components, enables the various parts to work together. During the use of the evaporator body, the rotatable adjustment screw drives the adjustment plate to move longitudinally, thereby squeezing and causing multiple scraper plates to slide on the outer wall of the adjustment sleeve. This allows for stable adjustment of the scraping diameter, thus adapting to evaporating liquids of different viscosities and improving film formation quality. The feeding component can preheat the material, and the rotating auger blades ensure that the material enters the evaporator evenly, improving evaporation quality and efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 The novel scraped evaporator shown includes an evaporator body 1 and an adjustment assembly. The adjustment assembly includes a top cover 2 that is detachably installed on the inner wall of the evaporator body 1, and a drive motor 3 is fixedly installed inside the top cover 2.

[0023] The adjustment assembly also includes a mounting ring 4, an adjustment sleeve 5 installed on the inner wall of the mounting ring 4, a plurality of scraper plates 6 with inclined inner walls slidably connected to the inner wall of the adjustment sleeve 5, a rotating sleeve 7 rotatably sleeved at the inner top of the adjustment sleeve 5, a sliding rod 8 slidably connected to the inner wall of the rotating sleeve 7, an adjustment disc 9 fixedly sleeved at the bottom of the outer wall of the sliding rod 8, an adjustment screw 10 threadedly connected to the inner wall of the adjustment disc 9, the adjustment screw 10 rotatably sleeved at the inner top of the mounting ring 4, a bolt groove opened at the end of the adjustment screw 10, and a feeding assembly provided at the upper top of the top cover 2.

[0024] The output end of the drive motor 3 is fixedly connected to the inner top end of the mounting ring 4 through the coupling sleeve 11, and a ceramic scraper 12 is installed on the outer wall of the scraper plate 6.

[0025] By adjusting the component settings, the adaptability of the evaporator is improved by using the adjustable scraper 6. The scraping adjustment is carried out according to the different viscosities of the evaporating liquid, thereby improving the uniformity of the scraping of the evaporating liquid. By rotating the adjusting screw 10, the adjusting plate 9 can be rotated to move longitudinally, causing multiple scraper plates 6 to slide continuously from the inside to the outside inside the adjusting sleeve 5, adjusting the scraping space between the scraper plates 6 and the evaporator body 1. The operation of the drive motor 3 can drive the mounting ring 4 to rotate, thereby driving multiple scraper plates 6 to rotate. The ceramic scraper blades 12 on the outer wall of the scraper plate 6 improve the scraping film formation effect.

[0026] The feeding assembly includes a feeding bin 13 fixedly connected to the top of the top cover 2. A servo motor 14 is installed at the top of the feeding bin 13. The output end of the servo motor 14 extends through the feeding bin 13 into the interior and is equipped with an auger blade 15.

[0027] A heater 16 is installed on the outer wall of the feeding hopper 13. A monitoring instrument 17 is installed on the top of the heater 16 to monitor the heating temperature. A temperature sensor is located at the bottom of the feeding hopper 13 to detect the material temperature when it exits the hopper. A feed pipe 18 is fixedly connected to the outer wall of the feeding hopper 13. A flange is fixedly connected to the top of the feed pipe 18 for easy connection to a pipeline.

[0028] By setting a heater 16 on the feeding assembly, the evaporating liquid can be preheated through the feeding hopper 13, thereby improving its efficiency during scraping evaporation. The servo motor 14 can drive the auger blades 15 to rotate, so that the evaporating liquid enters the evaporator body 1 in a spiral shape and enters evenly inside the evaporator body 1, thereby increasing the speed of film formation of the evaporating liquid through impact.

[0029] A support base 21 is fixedly connected to the bottom end of the evaporator body 1, and there are multiple support bases 21.

[0030] A hook 22 is fixedly connected to the top of the top cover 2. The hook 22 is symmetrically arranged along the center of the evaporator body 1 to facilitate the lifting of the top cover 2.

[0031] The outer wall of the evaporator body 1 is respectively equipped with a first heating jacket 19 and a second heating jacket 20. The second heating jacket 20 is located at the bottom of the first heating jacket 19. The outer walls of the two first heating jackets 19 and the second heating jacket 20 are coated with an anti-rust coating. The first heating jacket 19 and the second heating jacket 20 realize the zoned heating method, which is convenient for heating the liquid at different depths and avoids energy waste. The support base 21 at the bottom of the evaporator body 1 can provide sufficient support and stability for the evaporator body 1, thereby maintaining safety. The hook 22 at the top of the top cover 2 makes it easy to open the evaporator body 1 and adjust the position of the multiple scraper plates 6.

[0032] The working process of this embodiment is as follows:

[0033] The top cover 2 can be lifted using external hoisting equipment and two hooks 22 to clean the interior, preventing residual evaporator liquid from mixing with subsequent evaporator liquid. This facilitates the evaporation of new evaporator liquid. An external rotating tool is used to align with the bolt groove at the end of the adjusting screw 10, and then rotated. This causes the adjusting plate 9 to move longitudinally on its outer wall, thereby causing multiple inclined scraper plates 6 to move on the inner wall of the adjusting sleeve 5. This adjusts the gap between the multiple scraper plates 6 and the inner wall of the evaporator body 1. At the same time, the self-locking property of the thread prevents the adjusting plate 9 from resetting, thereby improving the evaporation efficiency.
