Description

Technical Field

[0001] This utility model relates to the technical field of thin film evaporator maintenance equipment, specifically to an automatic scraper cleaning device for thin film evaporators. Background Technology

[0002] A thin-film evaporator is a type of evaporator characterized by the material liquid flowing in a film along the heating tube wall for heat transfer and evaporation. Its advantages include high heat transfer efficiency, fast evaporation rate, and short material residence time, making it particularly suitable for the evaporation of heat-sensitive substances. The evaporation process is usually achieved by scraping the liquid with a scraper to form a film. The scraper is usually composed of a shaft and externally connected scraper blades, and the overall cleanliness of the scraper directly affects the film formation effect.

[0003] Existing scraper cleaning solutions typically involve removing the scraper and manually rinsing and scraping off surface deposits. Since the scraper blades usually have sharp edges at the ends, manual operation can easily result in scratches. Furthermore, the scraper itself is quite heavy, which further increases the possibility of injury and is rather inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic scraper cleaning device for thin-film evaporators. It has the advantage of effectively cleaning the entire scraper and solves the problems of existing scraper cleaning solutions, which usually involve removing the scraper and manually rinsing and scraping off surface deposits. Since the scraper blades usually have sharp edges at the ends, manual operation can easily result in scratches. Furthermore, the heavy weight of the scraper itself increases the possibility of injury.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An automatic scraper cleaning device for a thin film evaporator includes a cleaning frame, a movable end support frame, a fixed end support frame and a scraper cleaning component. The movable end support frame is slidably and fixedly disposed outside the scraper cleaning component. The fixed end support frame is fixed to the end of the scraper cleaning component. A driving component that drives the scraper to rotate through the fixed end support frame is fixedly disposed outside the cleaning frame.

[0008] The movable end support frame consists of a support frame and a connecting sleeve. The connecting sleeve is slidably connected to the outside of the scraper cleaning component and is provided with fasteners on the outside. The top of the support frame is provided with a support groove.

[0009] The fixed end support frame consists of a fixed frame and a transmission sleeve. The outside of the transmission sleeve is rotatably connected to the fixed frame through a bearing and forms a transmission with the output end of the drive component.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the scraper cleaning component includes an electric slide rail fixed to the outside of the cleaning frame. A push cylinder is fixedly connected to the moving end of the electric slide rail. A cleaning nozzle and a detachable squeezing scraper are fixedly connected to the moving end of the push cylinder. The number of cleaning nozzles is two, located on both sides of the squeezing scraper. The top of the squeezing scraper has a scraping groove adapted to the scraper.

[0012] Furthermore, the cleaning nozzle is controlled by a solenoid valve and is always kept in operation only in front of the moving direction of the squeezing scraper.

[0013] Furthermore, a sensor group that is linked to the scraper cleaning component is fixedly installed on the outside of the support frame. The sensor group consists of a photoelectric switch that senses the position of the scraper and a shut-off switch that restricts the movement position of the moving end of the electric slide rail.

[0014] Furthermore, the driving component includes a drive motor fixed to the outside of the cleaning frame. Both the outside of the drive motor and the outside of the transmission sleeve are fixedly connected to a transmission ring. The two transmission rings are connected by a transmission belt. The drive motor is controlled by a photoelectric switch.

[0015] This utility model provides an automatic scraper cleaning device for thin-film evaporators. By setting a movable end support frame, it can be moved away from the fixed end support frame, so that the space between the two can accommodate the scraper. Then, one side of the scraper is placed inside the transmission sleeve, and the other end is placed directly in the support groove at the top of the support frame to complete the scraper assembly. After assembly, the drive component first drives the scraper to rotate through the transmission sleeve, so that it rotates to the scraper blade outside the scraper. At this time, the scraper blade cleaning component can clean the scraper blade outside the scraper. After a single scraper blade is cleaned, the drive component can directly drive the scraper to rotate again to facilitate the cleaning of the next scraper blade. It has the advantage of effectively cleaning the entire scraper. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides an automatic scraper cleaning device for a thin film evaporator, including a cleaning frame 1, a movable end support frame 2, a fixed end support frame 3, and a scraper cleaning component 4. The movable end support frame 2 is fixedly slidably disposed outside the scraper cleaning component 4, and the fixed end support frame 3 is fixed to the end of the scraper cleaning component 4. A driving component 5 is fixedly disposed outside the cleaning frame 1, which drives the scraper to rotate through the fixed end support frame 3.

[0023] The movable end support frame 2 consists of a support frame 21 and a connecting sleeve 22. The connecting sleeve 22 is slidably connected to the outside of the scraper cleaning component 4 and is provided with fasteners on the outside. The top of the support frame 21 is provided with a support groove.

[0024] The fixed end support frame 3 consists of a fixed frame 31 and a transmission sleeve 32. The outside of the transmission sleeve 32 is rotatably connected to the fixed frame 31 through a bearing and forms a transmission with the output end of the drive component 5.

[0025] In this embodiment, the scraper cleaning component 4 includes an electric slide rail 41 fixed to the outside of the cleaning frame 1. A push cylinder 42 is fixedly connected to the outside of the moving end of the electric slide rail 41.

There are two cleaning nozzles 43 located on both sides of the squeezing scraper 44. The top of the squeezing scraper 44 is provided with a scraping groove adapted to the scraper.

[0026] When the scraper cleaning component 4 with the above configuration is working, it prioritizes moving the moving end component by pushing the cylinder 42, so that the scraping groove can fit with the scraper. At the same time, during its overall movement, the object on the scraper surface can be effectively washed and scraped off by the spray from the cleaning nozzle 43.

[0027] In this embodiment, the cleaning nozzle 43 is controlled by a solenoid valve and is always kept in operation only in front of the moving direction of the squeezing scraper 44.

[0028] The above settings ensure that the scraped area is always prioritized for rinsing during the scraping process, thereby preventing high temperatures from being generated during the scraping process.

The sensor group 6 consists of a photoelectric switch that senses the position of the scraper and a shut-off switch that restricts the movement position of the moving end of the electric slide rail 41.

[0030] By setting up sensor group 6, the sliding distance of the scraper cleaning component 4 can be effectively limited, and the position of the scraper blade outside the scraper can also be effectively sensed.

[0031] In this embodiment, the driving component 5 includes a driving motor 51 fixed to the outside of the cleaning frame 1. Both the outside of the driving motor 51 and the outside of the transmission sleeve 32 are fixedly connected to a transmission ring 52. The two transmission rings 52 are connected by a transmission belt 53. The driving motor 51 is controlled by a photoelectric switch.

[0032] When the drive unit 5 is working, the drive motor 51 can be started directly, thereby driving the transmission sleeve 32 to rotate through the cooperation of the transmission ring 52 and the transmission belt 53.
