[0011] (3) Beneficial effects In summary, this utility model has the following beneficial effects: This MVR evaporation and concentration system uses a feed condensate preheating device. It is equipped with a crank handle, a first spring, and a second spring. Pulling the crank handle causes the first spring to pull the rotating plate upwards, causing the rotating plate to disengage the locking rod from the first locking groove. The rotating plate then moves a movable plate within the groove via a movable rod, allowing the limiting block to slide within the limiting groove. Simultaneously, cranking the crank handle causes the second spring to pull the movable shaft to rotate via the movable rod and movable plate. This movable shaft then drives a winding roller to wind up the connecting rope, causing the connecting rope to disengage the trapezoidal locking block from the second locking groove via the movable block. Releasing the crank handle engages one end of the locking rod within the first locking groove, fixing the position of the rotating plate and the trapezoidal locking block. Lifting the mounting housing upwards with the handle causes the mounting housing to disengage the moving frame from the fixed seat, facilitating cleaning and maintenance of the filter screen.

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them. Example

[0016] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0017] Please see Figure 1-5This utility model provides a technical solution: a feed condensate preheating device for an MVR evaporation and concentration system, including a preheater 1, an inlet pipe 2 fixedly connected to the side of the preheater 1, a feed pump 3 fixedly connected to the inlet pipe 2, a fixed base 4 fixedly connected to one end of the inlet pipe 2, an installation groove 6 opened on the top of the fixed base 4, a movable frame 5 movably connected inside the installation groove 6, a filter screen 7 fixedly connected inside the movable frame 5, an installation shell 8 fixedly connected to the top of the movable frame 5, bearings provided on the opposite inner walls of the installation shell 8, a common movable shaft 9 passing through the interior of the two bearings, a winding roller 10 fixedly connected to the surface of the movable shaft 9, a groove 11 opened on the top of the movable shaft 9, a movable plate 12 movably connected inside the groove 11, and the movable plate 1... A limiting block 14 is fixedly connected to the side of the 2. A limiting groove 13 is opened on the inner wall of the groove 11. The limiting block 14 is slidably connected inside the limiting groove 13. A movable rod 15 is fixedly connected to the top of the movable plate 12. A rotating plate 16 is fixedly connected to the top of the movable rod 15. A first spring 32 is movably sleeved on the surface of the movable rod 15. A locking rod 17 is fixedly connected to the bottom of the rotating plate 16. A first locking groove 18 is opened on the top of the mounting shell 8. One end of the locking rod 17 is locked inside the first locking groove 18. A crank handle 19 is fixedly connected to the top of the rotating plate 16. The same fixed plate 20 is fixedly connected to the opposite inner walls of the mounting shell 8. Through holes 22 are opened on the opposite surfaces of the two fixed plates 20. A connecting rope 21 is fixedly connected to the surface of the take-up roller 10. One end of the mounting plate 25 is fixedly connected to a movable block 25. A sliding hole 26 is provided on the surface of the movable block 25. The same sliding rod 23 is fixedly connected to the opposite surface of the mounting shell 8 and the fixed plate 20. The sliding rod 23 is slidably connected inside the sliding hole 26. A second spring 24 is movably sleeved on the surface of the sliding rod 23. A trapezoidal locking block 29 is fixedly connected to the side of the movable block 25. A second locking groove 30 is provided on the inner wall of the mounting groove 6. One end of the trapezoidal locking block 29 is locked inside the second locking groove 30. A water pipe 31 is fixedly connected to the surface of the fixed base 4. By setting up a crank handle 19, a first spring 32 and a second spring 24, by pulling the crank handle 19, under the elastic force of the first spring 32, the crank handle 19 drives the rotating plate 16 to rise, causing the rotating plate 16 to drive the locking rod 17 to disengage from the first locking rod. The groove 18 allows the rotating plate 16 to move within the groove 11 via the movable rod 15, causing the movable plate 12 to slide within the limiting groove 13. Simultaneously, by cranking the handle 19, the second spring 24 causes the handle 19 to rotate the movable shaft 9 via the movable rod 15 and the movable plate 12. This causes the movable shaft 9 to drive the winding roller 10 to wind up the connecting rope 21. The connecting rope 21 then moves the trapezoidal locking block 29 away from the second groove 30 via the movable block 25. Releasing the handle 19 causes one end of the locking rod 17 to engage inside the first groove 18, fixing the position of the rotating plate 16 and the trapezoidal locking block 29. Lifting the handle upwards from the mounting shell 8 causes the mounting shell 8 to move the moving frame 5 away from the fixed base 4.This facilitates cleaning and maintenance of filter screen 7.

[0018] Specifically, one end of the first spring 32 is fixedly connected to the movable plate 12, and the other end of the first spring 32 is fixedly connected to the inner wall of the groove 11.

[0019] By adopting the above technical solution, the first spring 32 is fixed.

[0020] Specifically, there are multiple first slots 18, which are arranged in a ring on the top of the mounting shell 8.

[0021] Specifically, one end of the second spring 24 is fixedly connected to the movable block 25, and the other end of the second spring 24 is fixedly connected to the fixed plate 20.

[0022] By adopting the above technical solution, the second spring 24 is fixed.

[0023] Specifically, the surface of the crank handle 19 is provided with a rubber sleeve, and the surface of the mounting housing 8 is fixedly connected with a handle.

[0024] By adopting the above technical solution, the friction between the crank handle 19 and the palm is increased by the rubber sleeve, which prevents the hand from slipping when operating the crank handle 19, and the handle facilitates the movement of the fixed shell.

[0025] Specifically, a slider 28 is fixedly connected to the surface of the movable block 25, and a groove 27 is provided on the inner wall of the mounting shell 8, with the slider 28 slidably connected inside the groove 27.

[0026] By adopting the above technical solution, the slider 28 slides inside the groove 27, which plays a role in limiting the movement of the movable block 25.

[0027] It should be noted that metal parts such as springs and levers that come into contact with high temperature and high humidity environments can be made of corrosion-resistant metal materials.

[0028] It should be noted that protective or lubrication mechanisms can be installed on parts such as slides and sliders according to the actual working conditions. This is common knowledge and will not be elaborated here.

[0029] The working principle of this utility model is as follows: When this utility model is in use and the filter screen 7 needs cleaning and maintenance, by pulling the crank handle 19 upward, under the elastic force of the first spring 32, the crank handle 19 drives the rotating plate 16 to rise, causing the rotating plate 16 to drive the locking rod 17 to disengage from the first locking groove 18. The rotating plate 16 then drives the movable plate 12 to move inside the groove 11 via the movable rod 15, causing the limiting block 14 to slide inside the limiting groove 13. At the same time, by shaking the crank handle 19, under the elastic force of the second spring 24, the crank handle 19 drives the movable shaft via the movable rod 15 and the movable plate 12. Rotating the 9th axis causes the movable shaft 9 to drive the winding roller 10 to wind up the connecting rope 21, causing the movable block 25 to slide on the surface of the slide rod 23. This allows the connecting rope 21 to drive the trapezoidal locking block 29 out of the second slot 30 via the movable block 25. By releasing the crank handle 19, one end of the locking rod 17 is locked inside the first slot 18, which can fix the position of the rotating plate 16 and the position of the trapezoidal locking block 29. By lifting the mounting shell 8 upwards with the handle, the mounting shell 8 can drive the moving frame 5 out of the fixed seat 4, allowing the filter screen 7 to be cleaned and maintained.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
