Description

Technical Field

[0001] This utility model relates to the field of plate evaporator technology, and in particular to a novel rectangular grid plate evaporator. Background Technology

[0002] An evaporator is a device used to convert liquid into gas, and it is widely used in refrigeration, air conditioning, food processing, chemical industry and other fields. Its main function is to absorb heat from the surrounding environment, causing the liquid to evaporate into gas at a lower temperature, thereby achieving the purpose of cooling or concentration. A plate evaporator is a highly efficient heat exchange device, usually composed of multiple flat metal plates. These plates are arranged alternately to form multiple flow channels for heat exchange between the liquid and the gas.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Currently, most existing evaporation processes use tubular evaporators to evaporate fluids. However, tubular evaporators have disadvantages such as large footprint and low heat transfer efficiency, making it difficult for them to effectively evaporate fluids. In addition, in traditional plate evaporators, a liquid film forms when the hot evaporation plate comes into contact with the fluid, which may reduce the contact area between the evaporation plate and the fluid, resulting in reduced evaporation efficiency. Therefore, those skilled in the art have provided a novel rectangular grid plate evaporator to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel rectangular grid plate evaporator. By setting rectangular support blocks on the upper surfaces of the first and second evaporator plates, the liquid film formed between the fluid and the heat exchange surface can be effectively broken during use, allowing for better evaporation of the fluid. The movable rod can move and adjust the first clamping plate, thereby allowing for the addition or reduction of the number of evaporator plates according to different needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A novel rectangular grid plate evaporator includes a base plate. Movable grooves are provided on the upper surface of the base plate near the front end and the rear end. Threaded rods are rotatably embedded in each of the two movable grooves. Movable rods are provided on the outer surface of the two threaded rods and on one side of the upper surface of the base plate near the front end and the rear end. A first clamping plate is provided between the two movable rods on one side of the four movable rods, and a second clamping plate is provided between the two movable rods on the other side of the four movable rods.

[0007] Multiple No. 1 evaporating plates and No. 2 evaporating plates are arranged between the first clamping plate and the second clamping plate. Multiple rectangular support blocks are fixedly arranged on the upper surface of each of the multiple No. 1 evaporating plates and No. 2 evaporating plates. Two embedded rods are embedded at the midpoint of the upper surface of each of the multiple No. 1 evaporating plates and No. 2 evaporating plates. A worm gear is rotatably embedded at the midpoint of one side of the base plate.

[0008] Furthermore, a first bevel gear is fixedly provided on one side of each of the two threaded rods, and a transmission shaft is rotatably embedded inside one side of the base plate. A second bevel gear is fixedly provided on both the front end and the rear end of the transmission shaft, and the two first bevel gears are respectively meshed with the two second bevel gears.

[0009] Furthermore, a worm gear is fixedly sleeved at the midpoint of the outer surface of the transmission shaft, and the worm and the worm gear are meshed together.

[0010] Furthermore, two of the four movable rods are threaded onto the outer surface of the threaded rod at their lower ends, and the lower ends of the other two movable rods are movably disposed inside the movable groove.

[0011] Furthermore, each of the multiple No. 1 evaporating plates and multiple No. 2 evaporating plates has an embedding groove on both sides near the front and rear ends. A connecting rod is embedded in each of the embedding grooves in the multiple No. 1 evaporating plates and multiple No. 2 evaporating plates. Each of the multiple No. 2 evaporating plates has multiple guide grooves on one side near the front and rear ends.

[0012] Furthermore, the outer surfaces of the four connecting rods are respectively embedded in the upper and lower ends of the first and second clamping plates at the front and rear ends, respectively, and support plates are fixedly installed at the front and rear ends of the bottom plate.

[0013] Furthermore, an output port is provided on the upper part of one side of the second clamping plate, a conveying port is provided at the midpoint of the lower part of one side of the second clamping plate, and discharge ports are provided on both sides at the midpoint of the lower part of one side of the second clamping plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a novel rectangular grid plate evaporator, which, by fixing multiple rectangular support blocks on the upper end face of the first and second evaporation plates, can provide a certain degree of support and fixation when multiple first and second evaporation plates are arranged alternately. At the same time, when the evaporator is in use, the fixed rectangular support blocks can disrupt the liquid film formed between the fluid and the evaporation plates, thereby enabling better contact between the fluid and the evaporation plates, evaporating the fluid, and stabilizing the heat exchange efficiency of the evaporator.

[0016] 2. The present invention proposes a novel rectangular grid plate evaporator. By opening two movable grooves on the upper end face of the base plate, the two threaded movable rods can be moved and adjusted by rotating the threaded rods in the movable grooves. At the same time, the position of the first clamping plate can also be moved, thereby allowing for better arrangement and combination of more No. 1 and No. 2 evaporation plates. The adjusted first clamping plate can also clamp and fix the combined No. 1 and No. 2 evaporation plates, thereby achieving a better sealing effect for the evaporator. Attached Figure Description

Multiple rectangular support blocks 14 are fixedly arranged on the upper end face of the multiple first evaporator plates 2 and second evaporator plates 3. Two embedded rods 6 are embedded at the midpoint of the upper end face of the multiple first evaporator plates 2 and second evaporator plates 3. A worm gear 19 is rotatably embedded at the midpoint of one side of the bottom plate 5.

[0027] Specifically, after a movable groove 13 is opened on the upper end face of the base plate 5, a threaded rod 22 can be rotatably embedded in the movable groove 13. At the same time, two of the four movable rods 4 are threaded onto the outer surface of the threaded rod 22, and the two movable rods 4 can be moved by the rotation of the threaded rod 22. The other two movable rods 4 can be fixed to one side of the upper end face of the base plate 5, near the front end and near the rear end. The two movable rods 4 can be fixed together by bolts with a first clamping plate 1, and the two fixed movable rods 4 can be fixed together by bolts with a second clamping plate 9. Multiple alternating first evaporation plates 2 and second evaporation plates 3 can be arranged between the first clamping plate 1 and the second clamping plate 9. The two embedded rods 6 embedded in the first evaporation plate 2 and the second evaporation plate 3 can be connected to each other. At the same time, one end of the embedded rod 6 can be embedded in one side of the upper end face of the second clamping plate 9 and fixed by bolts. The worm gear 19 is rotatably embedded on one side of the base plate 5, which can better drive the transmission shaft 18 with the worm wheel 20 sleeve to rotate.

[0028] Reference Figure 5 Each of the two threaded rods 22 has a first bevel gear 17 fixedly installed on one side, and a drive shaft 18 is rotatably embedded inside one side of the base plate 5. The drive shaft 18 has a second bevel gear 21 fixedly installed at both the front and rear ends. The two first bevel gears 17 are respectively meshed with the two second bevel gears 21.

[0029] Specifically, after the first bevel gear 17 is fixedly installed on one side of the two threaded rods 22, it can mesh with the second bevel gear 21 fixedly installed at the front and rear ends of the transmission shaft 18, so that the rotating transmission shaft 18 can drive the two threaded rods 22 to rotate, which can better drive the two movable rods 4 with threaded sleeves to move and adjust.

[0030] Reference Figure 5A worm gear 20 is fixedly sleeved at the midpoint of the outer surface of the drive shaft 18, and the worm 19 and the worm gear 20 are meshed together.

[0031] Specifically, after the worm gear 20 is fixedly sleeved on the outer surface of the drive shaft 18, the worm 19 and the worm gear 20 can be better connected, so that the worm 19 drives the drive shaft 18 to rotate.

[0032] Reference Figure 1 and Figure 2 Two of the four movable rods 4 are threaded at their lower ends onto the outer surface of the threaded rod 22, and the lower ends of the other two movable rods 4 are movably disposed inside the movable groove 13.

[0033] Specifically, after the lower ends of the two movable rods 4 are movably embedded in the movable groove 13, the lower ends of the movable rods 4 can also be threadedly connected to the threaded rod 22, so that the threaded rod 22 can drive the movable rods 4 to move and adjust in the movable groove 13.

Connecting rods 7 are embedded in the embedded grooves 15 in the multiple No. 1 evaporating plates 2 and multiple No. 2 evaporating plates 3. Multiple guide grooves 16 are provided on one side near the front and rear ends.

[0035] Specifically, after the embedding grooves 15 are opened in the multiple No. 1 evaporating plates 2 and multiple No. 2 evaporating plates 3, the connecting rod 7 can be better embedded in the embedding grooves 15, so that the connecting rod 7 can better drive the first clamping plate 1 and the second clamping plate 9 to clamp and fix the multiple No. 1 evaporating plates 2 and multiple No. 2 evaporating plates 3. At the same time, after the guide groove 16 is opened on the upper end face of the No. 2 evaporating plate 3, the fluid can be better transported.

Support plates 12 are fixedly installed near the front and rear ends of the bottom plate 5.

[0037] Specifically, after the connecting rod 7 is fitted and connected with the first clamping plate 1 and the second clamping plate 9, the bolt at one end of the outer surface of the rotating connecting rod 7 can be raised to play an auxiliary role in fixing the first clamping plate 1 and the second clamping plate 9. At the same time, the connecting rod 7 can improve the sealing of the combined first evaporation plate 2 and second evaporation plate 3. The support plate 12 set on the lower end face of the base plate 5 can support and fix the evaporator.

After fixing the first clamp 1 and the second clamp, the worm gear 19 with the handwheel can be rotated according to different usage conditions to move the first clamp 1, which is locked in place, to a suitable position. Multiple first evaporation plates 2 and second evaporation plates 3 can be alternately set between the first clamp 1 and the second clamp. At the same time, the user can connect the first clamp 1 and the second clamp, as well as the multiple first evaporation plates 2 and second evaporation plates 3, through four connecting rods 7.

The spliced ​​embedding rod 6 is embedded on the upper end of the multiple first evaporation plates 2 and second evaporation plates 3 to better fix the evaporator. Finally, the user can connect different pipes to the output port 8, conveying port 11 and discharge port 10 on one side of the second clamp 9 to use the evaporator.
