Description

[0002] Evaporation is the physical process of converting liquid into gas. Generally speaking, an evaporator is an object that converts liquid into gas. The evaporator is mainly composed of two parts: a heating chamber and an 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] Since the evaporated solution is mostly an aqueous solution, the evaporation process becomes a process of using water vapor as a heating agent to generate water vapor. For the sake of convenience in distinction, the water vapor used as a heat source is called heating steam or primary steam, and the steam evaporated from the solution is called secondary steam.

[0004] As the amount of water evaporated in the evaporation chamber increases, existing evaporators generally use continuous water addition to ensure the evaporation amount.

[0037] See also Figure 1-Figure 10 In an embodiment of the present invention, an evaporator includes:

[0038] An evaporator shell 1, and a water tank 2, an evaporation tank 3 and a condenser 4 fixedly installed in the evaporator shell 1, a conveying plate 17 fixedly installed in the evaporation tank 3, one side of the conveying plate 17 is connected to an air supply pipe 1701, and the other side of the conveying plate 17 is fixed with a plurality of conveying pipes 16 equidistantly distributed in a circle;

[0039] Also includes:

[0040] See also Figure 1-Figure 3 , Figure 5 , Figure 7 , Figure 8 , a conveying and regulating mechanism is arranged in the evaporator shell 1, and the conveying and regulating mechanism includes a fixed sleeve 7 fixedly installed in the evaporator shell 1, a rotating sleeve 8 is movably installed in the fixed sleeve 7, and a No. 1 spring 9 is sleeved on the fixed sleeve 7 and the rotating sleeve 8; it also includes a vertical groove 801 and an inclined groove 802 opened on the outer wall of the rotating sleeve 8, and a limit block 701 slidingly connected to the vertical groove 801 and the inclined groove 802 is fixed on the inner wall of the fixed sleeve 7, and a pumping assembly connected to the rotating sleeve 8 is arranged on the water tank 2, wherein the pumping assembly includes a rotating disk 10 fixedly installed at the end of the rotating sleeve 8, and a plurality of water delivery holes 1001 equidistantly distributed in a circle are opened on the rotating disk 10, and a water pump 5 is fixed on the water tank 2, and a water pipe 6 connected to the rotating disk 10 is connected to the water pump 5.

[0041] In detail, when the evaporator is in use, it is necessary to pump water into the heating tube 15. In the initial state, the No. 1 spring 9 is in a compressed state, so that the rotating sleeve 8 is located at the end of the stroke away from the fixed sleeve 7, the ends of the vertical slot 801 and the inclined slot 802 are connected, and the limit block 701 is located at the end of the stroke of the vertical slot 801 away from the inclined slot 802. The water delivery hole 1001 opened on the rotating disk 10 cooperates with the guide component. At this time, the water pump 5 works and pumps the water in the water tank 2 into the rotating disk 10 through the water guide pipe 6. The water in the rotating disk 10 will be transported to the guide component through the water delivery hole 1001 and enter the heating tube 15. As the water volume increases, Increase, the gravity on the rotating disk 10 increases, causing the rotating sleeve 8 to move toward the fixed sleeve 7 and compress the No. 1 spring 9. The rotating sleeve 8 will also drive the vertical slot 801 and the inclined slot 802 to move, causing the limit block 701 to slide in the vertical slot 801. When the amount of water in the heating tube 15 reaches a certain amount, the limit block 701 will disengage from the vertical slot 801 and enter the inclined slot 802, causing the rotating sleeve 8 to rotate. The rotating sleeve 8 will also drive the rotating disk 10 to rotate, so as to drive the water delivery hole 1001 to move, thereby reducing the connection between the water delivery hole 1001 and the guide assembly, thereby gradually reducing the water delivery amount, ensuring that the water in the heating tube 15 will not be excessive.

[0042] See also Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 The evaporator housing 1 is also provided with a guide assembly connected to the delivery regulating mechanism, and the guide assembly is connected to a heating pipe 15 connected to the delivery pipe 16. The delivery regulating mechanism can transport the water in the water tank 2 to the delivery pipe 16 through the guide assembly. The guide assembly includes a guide column 12 fixedly installed in the evaporator housing 1 and symmetrically arranged, and a water guide plate 11 rotatably connected to the rotating plate 10 is slidably installed on the guide column 12. The water delivery hole 1001 is also opened on the water guide plate 11. A hollow rod 13 connected to the water guide plate 11 is rotatably installed on the water guide plate 11, and the hollow rod 13 is fixedly connected to the heating pipe 15.

[0043] It should be noted that the water guide plate 11 is also provided with a water delivery hole 1001. Under the action of the guide column 12, it is ensured that when the rotating plate 10 rotates, the water guide plate 11 will not rotate. In the initial state, the water delivery hole 1001 provided on the water guide plate 11 and the water delivery hole 1001 provided on the rotating plate 10 are in a fully connected state. When water needs to be added to the heating tube 15, at this time, under the action of the water pump 5, the water in the water tank 2 is added to the rotating plate 10, and the water in the rotating plate 10 will be transported to the water guide plate 11 through the water delivery hole 1001. Thereby, water is transported to the heating tube 15 through the hollow rod 13. As the amount of water in the heating tube 15 increases, the gravity on the rotating disk 10 will also increase, causing the rotating disk 10 to move toward the fixed sleeve 7, and the limit block 701 will slide in the vertical groove 801. When the limit block 701 moves to the inclined groove 802, the rotating disk 10 will rotate, thereby driving the water supply hole 1001 to move, so that the conduction amount of the water supply hole 1001 opened on the water guide plate 11 is reduced, thereby gradually reducing the water supply amount until the water amount in the heating tube 15 is added to the specified amount.

[0044] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 , a rotary heating mechanism is arranged in the evaporator shell 1 and connected to the guide assembly, a heater 22 is connected to the rotary heating mechanism, and the rotary heating mechanism can control the heater 22 to work and drive the heating tube 15 to rotate when the guide assembly moves. The rotary heating mechanism includes a telescopic rod 23 fixedly mounted on the water guide plate 11, a first moving contact 24 is fixed at the end of the telescopic rod 23, and a first static contact 25 cooperating with the first moving contact 24 is fixed on the guide column 12. A rotating assembly is arranged in the evaporator shell 1, wherein the rotating assembly includes a rotating rod 18 rotatably mounted in the evaporator shell 1, a sliding sleeve 19 is slidably mounted on the rotating rod 18, a second gear 20 is fixed on the sliding sleeve 19, a first gear 14 meshing with the second gear 20 is fixed on the hollow rod 13, and a movable plate 21 rotatably connected to the hollow rod 13 is rotatably mounted on the sliding sleeve 19, and the movable plate 21 is fixedly connected to the heater 22.

[0045] Furthermore, in order to speed up the heating rate of the water in the heating tube 15, it is necessary to control the rotation of the heating tube 15 so that the water in the heating tube 15 is heated more evenly. In the initial state, the distance between the rotating disk 10 and the fixed sleeve 7 is the largest. Under the action of gravity, the telescopic rod 23 is telescopically extended and retracted to the maximum, and the distance between the first moving contact 24 and the first static contact 25 is the largest. As the amount of water entering the heating tube 15 increases, the water guide disk 11 will move toward the fixed sleeve 7, thereby driving the telescopic rod 23 to move, so that the distance between the first moving contact 24 and the first static contact 25 is the largest. The spacing between them decreases. When the limit block 701 enters the inclined groove 802, it means that the heating tube 15 is about to be filled, and the first moving contact 24 will move to the connection position with the first static contact 25. When the two contacts are connected, the heater 22 is controlled to work and the water in the heating tube 15 is heated. At the same time, the rotating rod 18 is controlled to rotate, and the rotating rod 18 also drives the second gear 20 to rotate, so that the first gear 14 meshing therewith rotates. The first gear 14 also drives the heating tube 15 to rotate through the hollow rod 13 to ensure that the water in the heating tube 15 is heated more evenly.

[0046] Preferably, if the water temperature in the heating tube 15 is heated to a certain value, the water will evaporate and gasify, and be transported to the conveying disk 17 through the conveying pipe 16, so that the steam will be discharged through the air supply pipe 1701. If the steam does not need to be transported, as the evaporation amount of water in the heating tube 15 gradually increases, the gravity acting on the rotating disk 10 decreases, and under the action of the No. 1 spring 9, the rotating disk 10 moves toward the initial position, and under the action of the water guide disk 11, the telescopic rod 23 moves toward the initial position until the first moving contact 24 is separated from the first static contact 25, and the heater 22 stops working.

[0047] See also Figure 2-Figure 5 , Figure 7 , Fig. 9 , Fig.10The second static contact 26 is fixedly mounted on the guide assembly, and a connection trigger mechanism is provided on the guide assembly, and a second moving contact 31 is connected to the connection trigger mechanism. The connection trigger mechanism can adjust the matching state of the second moving contact 31 and the second static contact 26 when the guide assembly moves. The connection trigger mechanism includes a guide plate 27 fixedly mounted on the water guide plate 11, and a support sleeve 28 is fixedly mounted on the guide plate 27. A support rod 29 is slidably mounted in the support sleeve 28, and the support rod 29 is fixedly connected to the second moving contact 31. A support assembly connected to the support rod 29 is provided on the guide plate 27, wherein the support assembly includes a fixedly mounted The conical ring 37 on the guide column 12, the movable ring 32 is fixed on the support rod 29, the support sleeve 28 is sleeved with a No. 2 spring 30, the two ends of the No. 2 spring 30 are respectively abutted against the movable ring 32 and the guide plate 27, the movable ring 32 is provided with an elastic structure cooperating with the conical ring 37, the elastic structure mentioned above includes a receiving sleeve 33 fixedly mounted on the movable ring 32, a movable rod 34 is slidably mounted in the receiving sleeve 33, a limiting wheel 35 is fixed at the end of the movable rod 34, the limiting wheel 35 is abutted against the conical ring 37, and a No. 3 spring 36 abutting against the movable ring 32 is sleeved on the movable rod 34 and the receiving sleeve 33.

[0048] Furthermore, the conical ring 37 can be divided into two parts, the first part is cylindrical and the second part is conical. In the initial state, the No. 2 spring 30 is in a compressed state, so that the support rod 29 is located at the end of the stroke away from the support sleeve 28, so that the second moving contact 31 and the second static contact 26 are in abutment. The No. 3 spring 36 is in a compressed state, so that the movable rod 34 is located at the end of the stroke away from the receiving sleeve 33, so that the limiting wheel 35 is in abutment with the conical ring 37 of the cylindrical part, and the limiting wheel 35 is about to move to the conical part of the conical ring 37. When it is necessary to heat and evaporate water, at this time, the water will enter the heating tube 15. As the amount of water increases, the water guide plate 11 will move toward the fixed sleeve 7. The water guide plate 11 will also drive the guide plate 27 to move and drive the support sleeve 28 to move. At this time, the No. 2 spring 30 is elastically released, so that the position of the support rod 29 will not change, ensuring that the second moving contact The head 31 is always in abutment with the second static contact 26. As the amount of water gradually increases, the support sleeve 28 moves until the stroke gradually increases. Until the compression of the No. 2 spring 30 reaches a minimum, the support sleeve 28 continues to move in the direction away from the second static contact 26, and drives the second moving contact 31 to move through the support rod 29. The second moving contact 31 will be separated from the second static contact 26, causing the water pump 5 to stop working. The support rod 29 will also drive the movable ring 32 to move, and drive the limiting wheel 35 to move through the receiving sleeve 33 and the movable rod 34. The limiting wheel 35 will move a very small stroke and will enter the conical position of the conical ring 37. At this time, the No. 3 spring 36 is elastically released and drives the movable rod 34 to move in the direction away from the receiving sleeve 33, so that the limiting wheel 35 slides along the conical surface of the conical ring 37, thereby controlling the support rod 29 to move toward the support sleeve 28 to increase the distance between the second moving contact 31 and the second static contact 26.

[0049] Preferably, as the amount of water evaporates in the heating tube 15 increases, the gravity on the water guide plate 11 decreases, the No. 1 spring 9 is elastically released, and drives the water guide plate 11 to move toward the initial position. The water guide plate 11 also drives the support sleeve 28 to move through the guide plate 27, thereby driving the second moving contact 31 to move toward the second static contact 26 through the support rod 29. Since the No. 3 spring 36 also provides a certain resistance to the support rod 29, the problem of damage to the water pump 5 due to a small decrease in the amount of water in the heating tube 15 and excessive contact frequency between the second moving contact 31 and the second static contact 26 can be avoided.
