Description

Technical Field

[0001] The present invention relates to the technical field of steam compressors, and particularly to an MVR centrifugal steam compressor. Background Art

[0002] The MVR evaporation system is a new type of evaporation system used to replace the conventional single-effect evaporation system or multi-effect evaporation system. Since it can consume relatively low electrical energy through mechanical pressurization to greatly increase the saturation pressure and saturation temperature of the secondary steam coming out of the evaporator, reduce or completely replace the usage of primary steam (also called live steam, motive steam), a large amount of latent heat of vaporization in the secondary steam can be recovered with relatively low electrical energy consumption, greatly reducing the energy consumption in the evaporation or concentration process, and achieving obvious energy-saving benefits.

[0003] In the prior art, the Chinese patent with the publication number "CN212055169U" discloses a centrifugal steam compressor with a heat insulation mechanism. The mesh tube is connected to the speed reduction tube, and heat dissipation fins are provided on the mesh tube, which can make the high-temperature gas dissipate heat faster. The speed reduction tube is connected to the heat insulation tube, and a cooling tube is provided inside the heat insulation tube. The water pump is connected to the cooling tube through a water tank, which can make the cooling water circulate in the cooling tube, keep the heat insulation tube at a relatively low temperature all the time, avoid the danger of personnel being scalded, protect the safety of personnel, and at the same time, it is more convenient for personnel to work, improving work efficiency, and solving the problems that when the existing centrifugal steam compressor is in use, the high-temperature gas discharged usually causes the pipe body to overheat, and if personnel accidentally touch it, it will cause personnel scalding, and at the same time, it is more inconvenient for personnel to work.

[0004] In the above-described solution, by installing heat dissipation fins on the mesh tube and through the circulating flow of cooling water, the heat in the compressed gas is discharged. However, in this solution, external dust will fall on the heat dissipation fins, and due to the adhesion of dust, the heat dissipation effect of the heat dissipation fins will be affected. And in some existing solutions, a heat exchanger is used to complete the heat dissipation. Most heat exchangers use heat dissipation fins. However, during the use of the heat dissipation fins, too much heat will concentrate around the heat dissipation fins. If these heats are not dissipated quickly, it will eventually cause damage to the heat dissipation fins, and ultimately affect the use effect of the MVR centrifugal steam compressor.

[0019] 1. In the present invention, when steam exchanges heat through the heat exchanger, the heat is dissipated by the heat dissipation fins on the heat exchanger. At the same time, the switch of the spray head and the switch of the electric push rod are turned on. The electric push rod drives the U-shaped frame plate to rise. The first tooth group and the second tooth group on the U-shaped frame plate are sequentially engaged with the reciprocating gear on the rotating shaft.

[0020] 2. In the present invention, when the U-shaped frame plate rises, it will synchronously drive the fixed rod to rise.

Then, by using the cooperation between the first driving rod and the L-shaped frame plate on the first sliding plate, and the cooperation between the second driving rod and the L-shaped frame plate on the second sliding plate, the cleaning rods on the first sliding plate and the second sliding plate will be limited by the stabilizing rod, so as to clean the dust between the heat dissipation fins, ensure that the heat dissipation fins are not affected by dust, and effectively maintain the cleanliness of the heat dissipation fins, thereby ensuring the efficient operation of the heat exchanger.

[0021] 3. In the present invention, the motor drives the worm on the output shaft to rotate. By using the cooperation between the worm and the driven worm wheel, when the driven worm wheel rotates, it will drive the fan blades to rotate through the drive shaft. The airflow generated by the fan blades will quickly blow away the heat on the heat dissipation fins and the heat that has not dissipated around the heat dissipation fins, effectively enhancing the use effect of the heat exchanger.

[0022] 4. In the present invention, when the worm rotates, it will cooperate with the worm gear teeth on the support block. The mounting block will be adjusted in angle through the cooperation between the sliding block and the sliding groove on the support block. The fan blades on the mounting block will be adjusted in angle synchronously. By adjusting the angle of the fan blades, the airflow generated by the fan blades can more effectively blow away the heat on the heat dissipation fins, effectively improving the use effect and efficiency of the entire steam compressor.

By sliding a single cleaning rod 27 between two heat dissipation fins 11, it is convenient to clean the dust on the heat dissipation fins 11, ensuring the heat dissipation effect of the heat dissipation fins 11.

[0037] In this embodiment, when the U-shaped frame plate 19 rises, it will synchronously drive the fixing rod 29 to rise. The U-shaped fixed plate 30 on the fixing rod 29 will drive the first connecting frame 31 and the second connecting frame 32 to rise.

Then, by the cooperation of the first driving rod 33 and the L-shaped frame plate 28 on the first sliding plate 25, and the cooperation of the second driving rod 34 and the L-shaped frame plate 28 on the second sliding plate 26, the cleaning rods 27 on the first sliding plate 25 and the second sliding plate 26 will be limited by the stabilizing rod 24, so as to clean the dust between the heat dissipation fins 11, ensuring that the heat dissipation fins 11 will not be affected by dust, effectively maintaining the cleanliness of the heat dissipation fins 11, and thus ensuring the efficient operation of the heat exchanger 7.

[0038] An installation cross - plate 36 is fixedly installed between two supporting vertical plates 12. A supporting block 37 is fixedly installed on the installation cross - plate 36. An arc - shaped groove 38 is formed on the supporting block 37. A worm gear tooth 39 is fixedly installed inside the arc - shaped groove 38. A sliding groove 40 is formed on the outer side surface of the supporting block 37. A sliding block 41 is slidably installed on the sliding groove 40.

The driven worm gear 48 is inside the driving groove 43. The fan blade 49 is above the installation block 42. Among them, in order to ensure that the driven worm gear 48 can drive the fan blade 49 to rotate highly, the number of teeth on the driven worm gear 48 is several times the number of teeth on the worm 46. Ensure that when the worm 46 rotates one circle, the driven worm gear 48 can rotate several circles. Since this technology is well - known to those skilled in the art, no specific elaboration is made here. And this motor 44 can rotate forward and backward to ensure that the installation block 42 makes an angle adjustment on the supporting block 37.

[0039] In this embodiment, the motor 44 drives the worm 46 on the output shaft 45 to rotate. By using the cooperation between the worm 46 and the driven worm gear 48, when the driven worm gear 48 rotates, it will drive the fan blade 49 to rotate through the driving shaft 47. The airflow generated by the fan blade 49 will quickly blow away the heat on the heat dissipation fins 11 and the heat that has not dissipated around the heat dissipation fins 11, effectively enhancing the use effect of the heat exchanger 7. And when the worm 46 rotates, it will cooperate with the worm gear tooth 39 on the supporting block 37. The installation block 42 will make an angle adjustment on the supporting block 37 through the cooperation between the sliding block 41 and the sliding groove 40. The fan blade 49 on the installation block 42 will make a synchronous angle adjustment. Through the angle adjustment of the fan blade 49, the airflow generated by the fan blade 49 can more effectively blow away the heat on the heat dissipation fins 11, effectively improving the use effect and efficiency of the entire steam compressor.

[0040] Working principle:

[0041] During use, the secondary steam (low - pressure and low - temperature) generated in the evaporation chamber 3 is sucked in and compressed by the first - stage fan, and the temperature and pressure increase slightly. The compressed steam enters the second - stage fan after passing through the heat exchanger 7 and is compressed again to the target pressure / temperature. Finally, the high - temperature steam enters the heater as a heat source and returns to the evaporation chamber 3 after condensation.

[0042] When steam exchanges heat through the heat exchanger 7, the heat dissipation fins 11 on the heat exchanger 7 are used to dissipate heat. At the same time, the switches of the spray head 15 and the electric push rod 18 are turned on. The electric push rod 18 is used to drive the U-shaped frame plate 19 to rise. The first tooth group 22 and the second tooth group 23 on the U-shaped frame plate 19 are successively engaged with the reciprocating gear 16 on the rotating shaft 13, so that the reciprocating gear 16 drives the cooling pipe 14 to swing reciprocally through the rotating shaft 13. The spray head 15 on the cooling pipe 14 will adjust the angle following the swing of the cooling pipe 14, so that the spray head 15 evenly sprays the cooling water on the heat dissipation fins 11, thereby promoting the heat dissipation effect of the heat dissipation fins 11;

[0043] When the U-shaped frame plate 19 rises, it will synchronously drive the fixed rod 29 to rise. The U-shaped fixed plate 30 on the fixed rod 29 will drive the first connecting frame 31 and the second connecting frame 32 to rise. The first driving rod 33 and the second driving rod 34 on the first connecting frame 31 and the second connecting frame 32 will rise synchronously. Then, the first driving rod 33 is used in cooperation with the L-shaped frame plate 28 on the first sliding plate 25, and the second driving rod 34 is used in cooperation with the L-shaped frame plate 28 on the second sliding plate 26, so that the cleaning rods 27 on the first sliding plate 25 and the second sliding plate 26 will be limited by the stabilizing rod 24, thereby cleaning the dust between the heat dissipation fins 11 to ensure that the heat dissipation fins 11 are not affected by dust and can effectively maintain the cleanliness of the heat dissipation fins 11;

[0044] The motor 44 drives the worm 46 on the output shaft 45 to rotate. By using the cooperation of the worm 46 and the driven worm wheel 48, the driven worm wheel 48 will drive the fan blade 49 to rotate through the drive shaft 47 when rotating. The airflow generated by the fan blade 49 will quickly blow away the heat dissipation fins 11 and the heat that has not dissipated around the heat dissipation fins 11, effectively enhancing the use effect of the heat exchanger 7. And when the worm 46 rotates, it will cooperate with the worm wheel teeth 39 on the support block 37. The mounting block 42 will be adjusted at an angle through the cooperation of the sliding block 41 and the sliding groove 40 on the support block 37. The fan blade 49 on the mounting block 42 will be adjusted at an angle synchronously. Through the angle adjustment of the fan blade 49, the airflow generated by the fan blade 49 can more effectively blow away the heat on the heat dissipation fins 11, effectively improving the use effect and efficiency of the entire steam compressor.
