Abstract
Description
Technical Field
[0001] This utility model discloses a novel structure of a Miller plate for a heat pump scraper, which relates to the field of evaporator equipment technology. Background Technology
[0002] A scraped-plate evaporator is a special type of evaporator primarily used for the evaporation or concentration of high-viscosity liquids. It uses mechanical scrapers to continuously clean the inner wall of the evaporator, preventing scaling or adhesion of material on the heat exchange surfaces and thus maintaining good heat exchange efficiency. During operation, the liquid is heated in the heating zone of the evaporator, evaporating into gas. Heating is typically achieved through heat sources such as steam or hot oil, with heat transferred to the liquid through the outer wall of the evaporator. A key feature of scraped-plate evaporators in the heat exchange process is the enhanced heat exchange efficiency achieved through the rotating scraper mechanism, making them particularly suitable for high-viscosity liquids that are prone to scaling or crystallization. In this type of evaporator, the liquid evaporates in the heating zone while the scraper system cleans the heat exchange surfaces, preventing deposits and scaling, thus ensuring the continuity and efficiency of the evaporation process.
[0003] In the heat exchange process of a scraped evaporator, a Miller plate is installed on the outer cylinder of the evaporator to increase heat exchange efficiency. Using a Miller plate as a heating insulator can effectively reduce costs, increase heat exchange effect, and does not reduce the strength of the plate. Miller plates are usually installed by welding, but their lifespan will be reduced and they may loosen during prolonged high-temperature operation. Therefore, a novel Miller plate structure for heat pump scrapers is needed to solve these problems. Utility Model Content
[0004] The purpose of this utility model is to provide a novel structure for the Miller plate to the heat pump scraper, which strengthens the connection between the Miller plate and the outer wall of the evaporator and increases its service life.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel structure for a heat pump scraper using a Miller plate, comprising a heat pump scraper cylinder, characterized in that: a Miller plate is installed below the heat pump scraper cylinder; the clamping device includes a fixed frame, a pressure rod is rotatably mounted on the fixed frame, a connecting rod is rotatably mounted on the middle part of the pressure rod, a transmission rod is rotatably mounted on the outer side of the front end of the connecting rod, the transmission rod is rotatably connected to the fixed frame, the connecting rod is installed on the outer side of the pressure rod, the connecting rod is installed on the inner side of the transmission rod, and a pressure block is provided on one side of the connecting rod and the pressure rod.
[0006] Preferably, two sets of clamping devices are symmetrically installed on both sides of the heat pump scraper cylinder.
[0007] Preferably, multiple sets of clamping devices are provided, and plates are installed between the clamping devices.
[0008] Preferably, a clamping plate is installed at the top of the pressure rod, the clamping plate is used to clamp the Miller plate, and an anti-slip pad is installed on the clamping plate.
[0009] Preferably, a spring is provided at the connection between the clamping plate and the pressure rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the operator controls all the pressing devices to rotate by turning the lever, and the pressure rod is raised. During operation, the lever drives the transmission rod to rotate clockwise, which drives the connecting rod installed in the transmission rod to rotate clockwise as well. The pressure block on the side of the connecting rod near the pressure rod presses the pressure rod, causing the pressure rod to rotate clockwise, so as to complete the downward pressing action. Using Miller plate as a heating interlayer can effectively reduce the cost input, increase the heat exchange effect, and the strength of the plate will not be reduced, thus reducing energy consumption.

[0015] 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.
[0016] Specific implementation examples:
[0017] like Figure 1 As shown, a novel structure of a Miller plate for a heat pump scraper includes a heat pump scraper cylinder 1, a Miller plate 3 installed below the heat pump scraper cylinder 1, and two sets of clamping devices 2 symmetrically installed on both sides of the heat pump scraper cylinder 1.
[0018] The heat pump scraper cylinder 1 is the main working position. The Miller plate 3 is installed below the heat pump scraper cylinder 1. Using the Miller plate 3 as a heat exchanger can effectively reduce the cost and increase the heat exchange effect. The strength of the plate will not be reduced, thus reducing energy consumption. The clamping device 2 is mainly used to strengthen the connection between the Miller plate 3 and the heat pump scraper cylinder 1. The clamping device 2 is installed on both sides of the heat pump scraper cylinder 1 to press and compact the Miller plate 3 from both sides.
[0019] like Figure 2 As shown, the clamping device 2 includes a fixed frame 21, on which a pressure rod 22 is rotatably mounted. A connecting rod 24 is rotatably mounted in the middle part of the pressure rod 22. A transmission rod 23 is rotatably mounted on the outer side of the front end of the connecting rod 24. The transmission rod 23 is rotatably connected to the fixed frame 21. The connecting rod 24 is mounted on the outer side of the pressure rod 22 and on the inner side of the transmission rod 23. A pressure block (not shown in the figure) is provided on the side of the connecting rod 24 near the pressure rod 22.
[0020] When the clamping device 2 is not in operation, the transmission rod 23 is located near the outer wall of the heat pump scraper cylinder 1 and the pressure rod 22 is raised. When in operation, the transmission rod 23 is rotated clockwise, which drives the connecting rod 24 installed in the transmission rod 23 to rotate clockwise. The pressure block on the side of the connecting rod 24 near the pressure rod 22 presses the pressure rod 22, causing the pressure rod 22 to rotate clockwise, so as to complete the downward pressing action.
[0021] Multiple sets of clamping devices 2 are provided, and a plate 25 is installed between the clamping devices 2;
[0022] Multiple sets of clamping devices 2 are connected by a lever 25. The operator controls all the clamping devices 2 to rotate through the lever 25. The clamping device 2 ends when the transmission rod 23 is engaged in the pressure rod 22.
[0023] A pressure plate 26 is installed at the top of the pressure rod 22. The pressure plate 26 is used to press the Miller plate 3. An anti-slip pad (not shown in the figure) is installed on the pressure plate 26.
[0024] The clamping plate 26 is used to press down the welded joint between the Miller plate 3 and the heat pump scraper cylinder 1, so as to securely install the Miller plate 3. When the Miller plate 3 needs to be replaced in the future, the clamping device 2 can be loosened. After the replacement is completed, the clamping device 2 is tightened again.
[0025] A spring 221 is provided at the connection between the clamping plate 26 and the pressure rod 22;
[0026] The spring 221 allows for a greater range of motion in the clamping plate 26, and the spring force of the spring 221 can provide clamping force again.
[0027] In summary, by having the operator control all the pressing devices 2 to rotate by turning the lever 25, the pressure rod 22 is raised. During operation, the lever 23 rotates clockwise, causing the connecting rod 24 installed in the lever 23 to rotate clockwise as well. The pressure block on the side of the connecting rod 24 near the pressure rod 22 presses the pressure rod 22, causing the pressure rod 22 to rotate clockwise, thus completing the downward pressing action.

All technical solutions within this concept are within the scope of protection of this application.
