[0002] Evaporation is the physical process of converting liquid into gas. Generally speaking, an evaporator is an object that converts liquid substances into gas. The evaporator is a very important component among the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, gasify and absorb heat, and achieve the effect of refrigeration. The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.
[0003] When processing materials through the evaporation chamber, it is necessary to process the condensed water in the evaporation chamber. Generally, a water outlet pipe is connected to the bottom of the evaporation chamber to discharge the condensed water. However, due to thermal expansion and contraction, the water outlet pipe is prone to breakage at the connection with the evaporation chamber, and constant maintenance is required, which not only affects work efficiency but also increases the cost of use. Therefore, a condensed water pipe structure for an evaporator heating chamber is needed to reduce the breakage of the condensed water pipe connection caused by thermal expansion and contraction to solve the above problem.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The following is combined with Figure 1-Figure 5 The specific implementation modes of the present utility model are further described in detail.
[0024] Depend on Figure 1-Figure 5 The utility model comprises an evaporation chamber 1 and a discharge chamber 2. In order to increase the service life of the evaporator, the discharge chamber 2 is sleeved on the outer side of the lower part of the evaporation chamber 1. A first water outlet 3 is provided on the side wall of the lower part of the evaporation chamber 1. A second water outlet 4 is provided on the side wall of the discharge chamber 2 in a certain area corresponding to the position of the first water outlet 3. The second water outlet 4 and the first water outlet 3 are staggered, that is, the horizontal height of the second water outlet 4 is lower than the first water outlet 3. A drain pipe 5 is connected between the first water outlet 3 and the second water outlet 4. Two fixed plates 6 are fixedly connected to the side of the drain pipe 5 close to the evaporation chamber 1. A movable plate 7 is provided on the front side of each fixed plate 6. Two fixed ropes 8 are fixedly connected to the rear side of each movable plate 7. A movable ring 9 that can move forward and backward is slidably connected to the middle part of the drain pipe 5 through a sliding key. Each fixed rope 8 passes through the corresponding fixed plate 6 and cooperates with the movable ring 9. A sealing ring 10 is provided at the front part of the drain pipe 5.
[0025] When in use, the two movable plates 7 can be passed through the first water outlet 3 in turn, and then the front side of the drain pipe 5 is aligned with the first water outlet 3 and the two fixed ropes 8 are pulled, and the fixed ropes 8 are matched with the movable ring 9, and then the position of the movable ring 9 is adjusted, so that the movable plate 7 and the fixed plate 6 cooperate with each other to clamp the side wall of the evaporation chamber 1, and the first water outlet 3 is sealed. At this time, the interior of the evaporation chamber 1 is connected with the second water outlet 4 through the drain pipe 5.
[0026] Furthermore, in order to achieve a better sealing effect, a first limiting groove 11 adapted to the movable plate 7 is provided on the inner side wall of the evaporation chamber 1 at a position corresponding to each movable plate 7, and a second limiting groove 12 adapted to the fixed plate 6 is provided on the outer side wall of the evaporation chamber 1 at a position corresponding to each fixed plate 6;
[0027] It should be noted that the fit between the movable plate 7 and the first limiting groove 11 , and between the fixed plate 6 and the second limiting groove 12 are all clearance fits. Under high temperature conditions in the evaporation chamber 1 , the movable plate 7 and the fixed plate 6 will not expand and damage the first limiting groove 11 and the second limiting groove 12 .
[0028] Further, two fixing sleeves 13 are provided in the middle of each fixing plate 6, each fixing rope 8 passes through the fixing plate 6 through the fixing sleeve 13, and a limit block 14 fixedly connected to the corresponding fixing rope 8 is provided on the rear side of each fixing sleeve 13, and a crescent block 15 corresponding to the limit block 14 is fixedly connected to the outer wall of the movable ring 9, and a crescent groove 16 is provided on the rear side of each crescent block 15 to cooperate with the limit block 14;
[0029] When fixing the drain pipe 5, after pulling and tightening the fixing rope 8, the fixing rope 8 can pass through the corresponding crescent block 15, and the front side of the limit block 14 is matched with the crescent groove 16, and then after moving the moving ring 9 backward, the limit block 14 is tightly matched with the crescent groove 16.
[0030] Furthermore, in order to facilitate the adjustment of the tightness of the fixing, an adjustment ring 17 threadedly connected to the drain pipe (5) is provided on the front side of the movable ring 9, and a connecting frame 18 is fixedly connected to the front side of the movable ring 9, and the front side of the connecting frame 18 abuts against the adjustment ring 17;
[0031] When in use, by rotating the adjusting ring 17, the adjusting ring 17 can be moved forward and backward relative to the drain pipe 5, and when the adjusting ring 17 moves backward, the connecting frame 18 pushes the moving ring 9 backward, thereby adjusting the position of the moving ring 9;
[0032] It should be noted that the adjustment ring 17 is not in direct contact with the evaporation chamber 1 , so its thermal deformation is small and does not affect the threaded connection between it and the drain pipe 5 .
[0033] Furthermore, in order to further increase the compressive deformation resistance of the drain pipe 5, a bending portion 19 is provided in the middle of the drain pipe 5;
[0034] It should be noted that after the evaporation chamber 1 is heated, its side wall will deform under the principle of thermal expansion and contraction, thereby changing the radius of the evaporation chamber 1 and the size of the first water outlet 3. When the radius of the evaporation chamber 1 changes, the distance between the outer wall of the evaporation chamber 1 and the inner wall of the discharge chamber 2 will change (that is, the distance becomes smaller). By setting the bending portion 19, the change in the distance between the outer wall of the evaporation chamber 1 and the inner wall of the discharge chamber 2 can be offset. At this time, the middle part of the drain pipe 5 is bent by force, thereby reducing the pressure on the side wall of the evaporation chamber 1 by the drain pipe 5.
[0035] Furthermore, in order to achieve a good sealing effect, a sealing groove 20 is opened at the front of the drain pipe 5 corresponding to the position of the sealing ring 10. The material of the sealing ring 10 is a nickel-based alloy with a thermal expansion coefficient greater than that of the evaporation chamber 1, such as Inconel600 nickel-chromium-iron based solid solution strengthened alloy. When the evaporation chamber 1 expands due to heat, the deformation of the sealing ring 10 is greater than the deformation of the first water outlet 3, which can ensure the stability of the seal between the drain pipe 5 and the first water outlet 3.
[0036] When the utility model is used, firstly, the two movable plates 7 can be sequentially passed through the first water outlet 3 and aligned with the corresponding first limiting groove 11, then the front side of the drain pipe 5 can be aligned with the first water outlet 3 and then the two fixing ropes 8 can be pulled to make the fixing plate 6 and the second limiting groove 12 cooperate with each other, and then the fixing rope 8 can be matched with the movable ring 9, and the adjusting ring 17 can be rotated to make the adjusting ring 17 move backward relative to the drain pipe 5, and then the movable ring 9 can be pushed backward through the connecting frame 18, so that the movable plate 7 and the fixing plate 6 can cooperate with each other to clamp the side wall of the evaporation chamber 1, and the first water outlet 3 can be sealed. At this time, the inside of the evaporation chamber 1 is connected to the second water outlet through the drain pipe 5. 4, after the evaporation chamber 1 is heated, its side wall will be deformed under the principle of thermal expansion and contraction, thereby changing the radius of the evaporation chamber 1, and at the same time changing the size of the first water outlet 3. When the radius of the evaporation chamber 1 changes, the distance between the outer wall of the evaporation chamber 1 and the inner wall of the discharge chamber 2 will change (that is, the distance becomes smaller). By providing the bending portion 19, the change in the distance between the outer wall of the evaporation chamber 1 and the inner wall of the discharge chamber 2 can be offset. At this time, the middle part of the drain pipe 5 is bent by force, reducing the pressure on the side wall of the evaporation chamber 1 subjected to the drain pipe 5, and the sealing stability between the drain pipe 5 and the first water outlet 3 can be ensured by the sealing ring 10.
[0037] The utility model has a novel structure, ingenious conception, and simple and convenient operation. Through this design, the service life of the evaporator is effectively increased, a good sealing effect between the drain pipe 5 and the evaporation chamber 1 is achieved, the drain pipe 5 is convenient to fix, and the compressive deformation resistance of the drain pipe 5 is further increased.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
