Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to a plate evaporator that is easy to assemble and disassemble. Background Technology

[0002] An evaporator mainly consists of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, causing it to boil and vaporize. The evaporation chamber completely separates the gas and liquid phases. The vapor generated in the heating chamber carries a large amount of liquid droplets. After entering the larger evaporation chamber, these liquid droplets are separated from the vapor through condensation or the action of a demister. A plate evaporator is an evaporation device that uses metal plates instead of round tubes as heat transfer elements. During the use of a plate evaporator, in order to avoid scaling and blockage, it needs to be cleaned and maintained frequently. However, the heat exchange plates are often connected by nuts and screws, which increases the workload of the staff during maintenance. Utility Model Content

[0006] The two sets of limiting components include two U-shaped outer shells disposed on the front and rear sides. The two U-shaped outer shells are fitted over the two clamping plates. A positioning block is fixedly connected to the opposite side of each of the two U-shaped outer shells. A rotating rod passes through the middle of the bottom of each U-shaped outer shell. A driving bevel gear is fixedly connected to the top of the rotating rod. A rotating shaft is rotatably connected to both sides of the inner cavity of each U-shaped outer shell. A driven bevel gear is fixedly connected to the side of each of the two rotating shafts that is close to each other.

A guide rod is provided on one side of each of the two rotating cylinders. A sliding block is slidably connected to the surface of each of the two guide rods. An extension slide rod is fixedly connected to the side of each of the two sliding blocks that is close to the rotating cylinder. A connecting plate is fixedly connected to the side of each of the two sliding blocks that is far from the extension slide rod. A connecting rod is fixedly connected to the side of each of the two connecting plates that is close to each other. The end of each of the two connecting rods that is far from the connecting plate extends to the outside of the U-shaped outer shell.

The two sets of limiting components 4 include U-shaped outer shells 401 disposed on the front and rear sides. The two U-shaped outer shells 401 are fitted over the two clamping plates 1. Positioning blocks 402 are fixedly connected to opposite sides of the two U-shaped outer shells 401. A rotating rod 403 passes through the middle of the bottom of the U-shaped outer shell 401. A drive bevel gear 404 is fixedly connected to the top of the rotating rod 403. Rotating shafts 405 are rotatably connected to both sides of the inner cavity of the U-shaped outer shell 401. The two rotating shafts 405 are positioned close to each other on the sides of their respective sides. A driven bevel gear 406 is fixedly connected. Rotating cylinders 407 are fixedly connected to the sides of the two rotating shafts 405 that are far apart from each other. The surfaces of the two rotating cylinders 407 are provided with spiral grooves 408. Guide rods 409 are provided on one side of the two rotating cylinders 407. Sliding blocks 410 are slidably connected to the surfaces of the two guide rods 409. Extension rods 411 are fixedly connected to the sides of the two sliding blocks 410 that are close to the rotating cylinders 407. Connecting plates 412 are fixedly connected to the sides of the two sliding blocks 410 that are far away from the extension rods 411. Connecting rods 413 are fixedly connected to the sides of the two connecting plates 412 that are close to each other. The ends of the two connecting rods 413 that are far away from the connecting plates 412 extend to the outside of the U-shaped outer shell 401.

[0025] like Figure 2 , Figure 4 As shown, the positioning block 402 is connected to the heating plate 3 by the positioning groove 5. Both driven bevel gears 406 are meshed with the driving bevel gear 404. The two spiral grooves 408 are symmetrically arranged. The ends of the two extended slide rods 411 that are away from the sliding block 410 extend into the interior of the two spiral grooves 408 and slide in connection with the inner wall of the spiral grooves 408. The middle of the front and rear sides of the two pressing plates 1 are provided with connecting holes 6. The end of the connecting rod 413 that extends to the outside of the U-shaped shell 401 is connected to the connecting hole 6. The ends of the two guide rods 409 that are far apart from each other are fixedly connected to the inner walls of the two sides of the U-shaped shell 401.

A screw 7 connects the two clamping plates 1 through threaded holes 2. A U-shaped outer shell 401 is snapped onto the outside of the two clamping plates 1. A rotating rod 403 rotates the driving bevel gear 404. The driving bevel gear 404, through the driven bevel gear 406, drives two rotating shafts 405 together with a rotating cylinder 407 to rotate. During the rotation of the rotating cylinder 407, under the action of the spiral groove 408, it can utilize the extension... The long sliding rod 411 drives the sliding block 410 to slide towards the middle, and the two connecting rods 413 extend into the interior of the connecting hole 6 to fix the U-shaped outer shell 401. The positioning block 402 is engaged with the inner side of the positioning groove 5 to limit the heating plate 3. The reverse rotation rod 403 and the active bevel gear 404 can make the U-shaped outer shell 401 and the positioning block 402 move away from the sides of the pressing plate 1 and the heating plate 3, so that the heating plate 3 can be pulled out from between the pressing plates 1, which is convenient for the replacement and maintenance of the heating plate 3.
