DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 7 , an evaporator for aluminum oxide production, comprising an evaporator 1 and a supporting mechanism 2 arranged at the bottom thereof, a positioning mechanism 3 is connected between the evaporator 1 and the supporting mechanism 2, and the evaporator 1 comprises an evaporator body 101:

[0025] Furthermore, the evaporator body 101 is fixedly connected to a fixed shell 102 on the left and right sides, a plurality of connecting rods 103 are fixedly connected to the bottom of the fixed shell 102, a fixed sleeve 104 is fixedly connected to the bottom of the connecting rod 103, and a positioning rod 109 is slidably connected to the front and rear sides of the fixed sleeve 104. The opposite end of the positioning rod 109 extends to the outside of the fixed sleeve 104 and is mutually clamped with the positioning mechanism 3.

[0026] The evaporator body 101 is the core part of the entire evaporation device and is responsible for completing the evaporation process of the liquid. The evaporator body 101 is provided with a fixed shell 102 on both sides. This design enhances the overall stability and structural strength of the equipment and also provides an installation platform for other components. The bottom of the fixed shell 102 is connected to the fixed sleeve 104 through a connecting rod 103, forming an effective transition and bearing structure from the evaporator body 101 to the bottom support mechanism 2. The combination of the connecting rod 103 and the fixed sleeve 104 ensures the stability of the evaporator 1 during operation and prevents displacement or vibration caused by uneven force. A slidable positioning rod 109 is provided inside the fixed sleeve 104. This design allows the evaporator 1 to be accurately positioned and fixed during installation or removal. The positioning rod 109 can slide back and forth inside the fixed sleeve 104, and at its other end it is mutually engaged with the positioning mechanism 3. In this way, the evaporator 1 can be accurately fixed on the support mechanism 2 to ensure the stability and safety of the equipment during operation. The structural design of the equipment not only ensures the stable operation of the evaporator 1, but also facilitates rapid installation and positioning and necessary maintenance and disassembly operations, greatly improving the convenience and flexibility of the use of the evaporator 1.

[0027] Furthermore, a sliding groove 105 and a clamping groove 106 are provided on the opposite side of the fixing sleeve 104, a limiting groove 107 is provided on the inner wall of the fixing sleeve 104, a limiting plate 108 is slidably connected inside the limiting groove 107, and the opposite side of the limiting plate 108 is fixedly connected to one end of the positioning rod 109, and a first spring 111 is fixedly connected between the opposite sides of the limiting plate 108.

[0028] The fixing sleeve 104 is provided with a slide groove 105 and a card groove 106 on the opposite side thereof. These two slot designs work together to act on the movement and locking of the positioning rod 109. The slide groove 105 allows the positioning rod 109 to slide smoothly in the fixing sleeve 104, while the card groove 106 is used to realize the fixed position locking of the positioning rod 109. The inner wall of the fixing sleeve 104 is also specially provided with a limit groove 107, and a limit plate 108 is slidably connected inside the limit groove 107. The limit plate 108 is fixedly connected to one end of the positioning rod 109. Therefore, when the positioning rod 109 moves, the limit plate 108 also moves synchronously therewith, playing a guiding and limiting role. The role of the first spring 111 is that after the positioning rod 109 is unlocked, the positioning rod 109 can be automatically reset or maintain a certain pre-tightening force with the help of elastic force, thereby ensuring that the positioning rod 109 can always be in the correct position when not affected by external force, and at the same time it can also buffer the impact caused by external force, protect the equipment from damage, and maintain a stable connection state.

[0029] Furthermore, the limiting plate 108 is slidably connected to the inner wall of the fixing sleeve 104 , a fixing rod 110 is fixedly connected to one side of the positioning rod 109 , and the fixing rod 110 is slidably connected to the slide groove 105 and is mutually engaged with the clamping groove 106 .

[0030] When the positioning rod 109 slides into place in the slide groove 105 through the fixing rod 110, the fixing rod 110 will be embedded in the card slot 106, thereby firmly locking the positioning rod 109 in the desired position, thereby ensuring a stable connection between the evaporator body 101 and the support mechanism 2. The above design uses multiple sliding connections and card-connecting structures to enable the evaporator 1 to be flexibly and quickly positioned during installation and disassembly, while ensuring a firm and reliable connection, thereby greatly improving the stability and durability of the equipment.

[0031] Furthermore, the positioning mechanism 3 includes a positioning plate 301, a clamping plate 302 is fixedly connected to the opposite side of the positioning plate 301, the clamping plate 302 is clamped with the fixed shell 102, a connecting frame 303 is fixedly connected to the bottom of the positioning plate 301, and a positioning sleeve 304 is fixedly connected to the front and rear sides of the connecting frame 303.

[0032] The clamping plate 302 is provided to form a tight snap fit with the fixed shells 102 on both sides of the evaporator body 101. When the positioning rod 109 is snapped with the slots 106 in the fixed sleeve 104 through the connecting rod 103, the positioning plate 301 is engaged with the fixed shell 102 through the clamping plate 302, thereby further strengthening the fixed connection between the evaporator 1 and the supporting mechanism 2, thereby ensuring the absolute stability of the equipment after installation.

[0033] Furthermore, a pin rod 305 is slidably connected inside the positioning sleeve 304 , one end of the pin rod 305 is slidably connected to the positioning rod 109 , and a third spring 306 is fixedly connected between the positioning sleeve 304 and the pin rod 305 .

[0034] When the positioning rod 109 is inserted into the positioning sleeve 304, the pin rod 305 can interact with the positioning rod 109. Specifically, one end of the pin rod 305 is slidably connected to the positioning rod 109. When the positioning rod 109 moves, the pin rod 305 will also slide accordingly. This design helps to increase the stability of the positioning rod 109 in the positioning sleeve 304 and prevent it from loosening or falling off. The third spring 306 can provide appropriate elastic resistance during the process of inserting or withdrawing the positioning rod 109 from the positioning sleeve 304, ensuring that the positioning rod 109 can still maintain a good contact and positioning state in the absence of external force. At the same time, it can also absorb vibration and impact to a certain extent, thereby extending the service life of the equipment and improving the stability and reliability of the overall system.

[0035] Furthermore, the support mechanism 2 includes a U-shaped plate 201 , a cross bar 202 is fixedly connected to the top of the inner wall of the U-shaped plate 201 , a positioning plate 301 is fixedly connected to the left and right ends of the surface of the cross bar 202 , and a holder 207 is fixedly connected to the bottom of the positioning plate 301 .

[0036] The U-shaped plate 201 provides stable support for the bottom of the evaporator 1 with its unique U-shaped structure. A cross bar 202 is fixedly connected to the top of the inner wall of the U-shaped plate 201. The cross bar 202 spans the entire internal space of the U-shaped plate 201, thereby enhancing the overall rigidity and stability of the support mechanism 2. Through the cooperation of the bracket 207 and the positioning rod 109, not only can the movement of the evaporator 1 on the horizontal plane be restricted, but also the connection between the evaporator 1 and the support mechanism 2 is made tighter and more stable.

[0037] Furthermore, a rotating rod 206 is rotatably connected to the bottom of the base 207, one end of the rotating rod 206 is rotatably connected to a sliding sleeve 204, the inner wall of the sliding sleeve 204 is slidably connected to a sliding rod 203, the sliding rod 203 is fixedly connected to the inner wall of the U-shaped plate 201, and a second spring 205 is movablely sleeved on the surface of the sliding rod 203 and fixedly connected to the opposite side of the sliding sleeve 204.

[0038] When the evaporator 1 is vibrated or slightly displaced, the second spring 205 can automatically adjust the relative position between the sliding sleeve 204 and the sliding rod 203, playing a role of stable support and shock absorption, thereby effectively protecting the evaporator 1 and the supporting mechanism 2 from damage and ensuring the smooth and durable operation of the equipment.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
