Description

Technical Field

[0001] The invention relates to the technical field of water chillers, and in particular to a high-precision industrial water chiller for evaporation-condensation heat recovery. Background Art

[0002] At present, when the chiller is running, it will discharge a large amount of condensation heat into the environment through the cooling water system, causing the ambient temperature to rise. This not only wastes energy and causes environmental thermal pollution, but also easily causes the working environment of the chiller to deteriorate, affecting the working efficiency of the unit. During the operation of the chiller, the temperature at the end of the condenser is too low, causing supercooled liquid to enter the evaporator, which will cause the evaporator to frost. As the surface temperature of the evaporator continues to drop, a frost layer is formed. The formation of the frost layer will further reduce the heat exchange efficiency of the evaporator surface, resulting in a lower evaporator temperature, thus forming a vicious circle and making the frosting phenomenon more and more serious. The frosting of the evaporator will not only affect the heat exchange efficiency of the system, but may also cause the evaporator to be blocked, increase system resistance, reduce cooling capacity, and even cause other faults. In addition, after the chiller has been running for a long time, scale will form on the copper tube inside the condenser. The formation of scale will affect the normal operation of the condenser. Therefore, in order to solve the above problems, a new type of chiller is needed. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The condenser 2 comprises a main body 3, a mounting plate 10 fixedly arranged at the end of the main body 3 for fixing a copper tube, a transfer tube 4 fixedly arranged on the mounting plate 10, a filter plate 7 coaxially fixedly arranged in the transfer tube 4 and a cover 8 fixedly arranged at the end of the transfer tube 4 (such as Figure 4 As shown in the figure, the two ends of the transfer tube 4 are provided with a liquid outlet pipe 5 and a liquid inlet pipe 6, a cold liquid pipe 9 is provided between the condenser 2 and the evaporator 46, the cleaning mechanism includes a transmission rod 16 rotatably arranged on the filter plate 7 and a cleaning brush 17 symmetrically fixedly arranged at the end of the transmission rod 16, and the defrosting mechanism includes a heat collecting pipe 40 fixedly arranged on the liquid outlet pipe 5 and a heat releasing pipe 44 fixedly arranged on the cold liquid pipe 9 (as shown in the figure). Figure 3As shown), a heat conducting pipe 45 is arranged between the heat releasing pipe 44 and the heat collecting pipe 40, and the transmission unit includes a power mechanism and a reciprocating swing mechanism, the power mechanism has a power output end, the reciprocating swing mechanism has a swing output end, the power output end is transmission-connected to the swing output end, and the swing output end is transmission-connected to the transmission rod 16.

[0031] When the chiller is running, the cold liquid enters from the liquid inlet pipe 6, passes through the filter plate 7, then enters the copper tube and flows to the filter plate 7, and finally flows out from the liquid outlet pipe 5 (a number of U-shaped copper tubes are arranged on the mounting plate 10, which is a mature existing structure and is therefore not shown in the figure). After the above circulation, the cold liquid absorbs heat in the copper tube and heats up, and finally flows out from the liquid outlet pipe 5. When the condenser 2 is running, the power mechanism drives the reciprocating swing mechanism to run, and then the swing output end of the reciprocating swing mechanism drives the transmission rod 16 to rotate reciprocatingly, and the reciprocating rotation of the transmission rod 16 drives the cleaning brush 17 to swing reciprocatingly, so that the cleaning brush 17 cleans the filter plate 7 to prevent impurities from clogging the filter holes on the filter plate 7 after the condenser 2 has been running for a long time, thereby slowing down the formation of scale in the condenser 2, extending the service life of the condenser 2, and further extending the service life of the chiller, and when the cold liquid absorbs heat and flows out from the liquid outlet pipe 5, the heat collecting pipe 40 will absorb heat, and then the heat enters the heat release pipe 44 through the heat conduction pipe 45, thereby preheating the cold liquid pipe 9 to prevent the liquid temperature entering the evaporator 46 from being too low, thereby avoiding frosting of the evaporator 46.

[0032] In order to show the installation structure of the transmission rod 16 in the transfer tube 4, the following features are also specifically provided:

[0033] The cleaning mechanism also includes a first partition 11, a second partition 14, a mounting tube 12 and a receiving tube 15. The first partition 11 is fixedly arranged on the mounting plate 10, the second partition 14 is fixedly arranged on the filter plate 7, one end of the filter plate 7 is fixedly connected to the first partition 11, and the other end is fixedly connected to the second partition 14, and the end of the second partition 14 away from the filter plate 7 is fixedly connected to the sealing cover 8. A mounting tube 12 is formed in the middle of the first partition 11, and a receiving tube 15 is formed in the middle of the second partition 14. The mounting tube 12 and the receiving tube 15 are both provided with sliding arc grooves 13 at one end close to the filter plate 7, and a cleaning brush 17 is slidably arranged in each sliding arc groove 13. The transmission rod 16 is rotatably arranged in the receiving tube 15 and the mounting tube 12, and the mounting tube 12 and the receiving tube 15 are both dynamically sealed and connected to the transmission rod 16.

[0034] Combination Figure 4 , Figure 5 and Figure 6 The first partition 11 and the second partition 14 divide the space inside the transfer tube 4 into two parts, upper and lower parts. Figure 4As shown, as the equipment is running, the transmission rod 16 reciprocates and continuously drives the cleaning brush 17 to swing, cleaning the upper and lower halves of the filter plate 7 to prevent impurities from clogging the filter holes of the filter plate 7.

[0035] In order to show the detailed structure of the power mechanism, the following features are also set:

[0036] The power mechanism also includes a water pipe seat 21 fixedly arranged on the liquid inlet pipe 6, a receiving frame 26 coaxially fixedly arranged in the liquid inlet pipe 6, a power shaft 28 rotatably arranged on the receiving frame 26, and a first impeller 27 coaxially fixedly arranged on the power shaft 28. One end of the power shaft 28 is rotatably connected to the receiving frame 26, and the other end passes through the water pipe seat 21. The power shaft 28 and the water pipe seat 21 are dynamically sealed and connected. The power shaft 28 is the power output end of the power mechanism.

[0037] The water pipe seat 21 is connected to an external liquid pumping device, and then the liquid flows into the liquid inlet pipe 6 through the water pipe seat 21. When the liquid flows from the liquid inlet pipe 6 into the transfer pipe 4, the liquid flow drives the first impeller 27 to rotate, and the rotation of the first impeller 27 drives the power shaft 28 to rotate, and the rotation of the power shaft 28 drives the reciprocating swing mechanism to operate.

[0038] In order to show the detailed structure of the reciprocating swing mechanism, the following features are also set:

[0039] The reciprocating swing mechanism also includes a rotating pillar 29 fixedly arranged on the cover 8, a broken gear 30 rotatably arranged on the rotating pillar 29, a rotating bracket 31 coaxially fixedly arranged on the broken gear 30, a broken gear ring 32 coaxially fixedly arranged on the rotating bracket 31, a bearing support plate 34 fixedly arranged on the cover 8 and a power gear 35 rotatably arranged on the bearing support plate 34. The power gear 35 is colinear with the axis of the transmission rod 16. The broken gear 30 and the broken gear ring 32 are not meshed with the power gear 35 at the same time. The power gear 35 is the swing output end of the reciprocating swing mechanism. The power gear 35 is connected to the transmission rod 16, and the rotating bracket 31 is connected to the power shaft 28.

[0040] When the device is running, the power shaft 28 drives the rotating bracket 31 to rotate, and the rotation of the rotating bracket 31 drives the residual gear ring 32 and the residual gear 30 to rotate simultaneously. The residual gear ring 32 and the residual gear 30 successively mesh with the power gear 35, causing the power gear 35 to reciprocate, and the reciprocating rotation of the power gear 35 drives the transmission rod 16 to reciprocate.

[0041] In order to show the connection relationship between the power shaft 28 and the rotating bracket 31, the following features are also specifically provided:

[0042] A bevel gear frame 22 is fixedly provided on the water pipe seat 21, and a first bevel gear 23 and a second bevel gear 24 are rotatably provided on the bevel gear frame 22, respectively. The first bevel gear 23 is meshed with the second bevel gear 24, and the first bevel gear 23 is connected to the power shaft 28 through a pulley. A receiving shaft 25 is coaxially fixed on the second bevel gear 24. The reciprocating swing mechanism also includes a worm 39 rotatably provided on the cover 8 through a bearing and a worm wheel 33 coaxially fixed on the rotating bracket 31. The worm wheel 33 is meshed with the worm 39, and the worm 39 is connected to the receiving shaft 25 through a pulley.

[0043] When the power shaft 28 rotates, the power shaft 28 drives the first bevel tooth 23 to rotate, the rotation of the first bevel tooth 23 drives the second bevel tooth 24 to rotate, the rotation of the second bevel tooth 24 drives the receiving shaft 25 to rotate, the rotation of the receiving shaft 25 drives the worm 39 to rotate, the rotation of the worm 39 drives the worm wheel 33 to rotate, the rotation of the worm wheel 33 drives the rotating bracket 31 to rotate, and a labor-saving structure is formed between the worm wheel 33 and the worm 39, which is more convenient for device transmission.

[0044] In order to show the connection relationship between the power gear 35 and the transmission rod 16, the following features are also specifically provided:

[0045] A first magnetic ring 36 is coaxially fixedly disposed on the power gear 35 , and a second magnetic ring 18 is coaxially fixedly disposed on the end of the transmission rod 16 . The first magnetic ring 36 and the second magnetic ring 18 are coaxially disposed.

[0046] The rotation of the power gear 35 drives the first magnetic ring 36 to rotate, the rotation of the first magnetic ring 36 drives the second magnetic ring 18 to rotate, and the rotation of the second magnetic ring 18 drives the transmission rod 16 to rotate. It should be noted that the transmission principle of the first magnetic ring 36 and the second magnetic ring 18 here is the same as that of the magnetic coupler.

[0047] In order to ensure that the forward rotation angle and the reverse rotation angle of the transmission rod 16 are the same, the following features are also specifically provided:

[0048] A retaining ring 19 is coaxially fixed on the transmission rod 16, and two contact blocks 20 are symmetrically formed on the outer wall of the retaining ring 19. A blocking ring 37 is fixed on the cover 8, and the axis of the blocking ring 37 is colinear with the axis of the transmission rod 16. Two blocks 38 are symmetrically formed on the inner wall of the blocking ring 37, and the vertical center planes of the two blocks 38 are parallel to the center planes of the first partition 11 and the second partition 14.

[0049] When the power gear 35 rotates back and forth, during the forward rotation of the power gear 35, the rotation of the power gear 35 is transmitted to the transmission rod 16 through the first magnetic ring 36 and the second magnetic ring 18. The rotation of the transmission rod 16 causes the retaining ring 19 to rotate until the contact block 20 abuts against the stop block 38. At this time, the transmission rod 16 has driven the cleaning brush 17 to swing to clean the filter plate 7. At this time, if the power gear 35 continues to rotate, the first magnetic ring 36 will also continue to rotate. However, since the first magnetic ring 36 and the second magnetic ring 18 are magnetically connected, the continued rotation of the first magnetic ring 36 will not drive the second magnetic ring 18 to rotate, thereby preventing the power gear 35 from driving the transmission rod 16 to rotate excessively, causing the cleaning brush 17 to collide with the first partition plate 11 or the second partition plate 14. Similarly, when the power gear 35 reverses, the above structure will also prevent the cleaning brush 17 from colliding with the first partition plate 11 or the second partition plate 14, and the setting of the contact block 20 and the stop block 38 can make the angle of the transmission rod 16 the same for each forward and reverse rotation.

[0050] In order to ensure that the heat emitted from the liquid outlet pipe 5 can quickly reach the heat conducting pipe 45 when the device is running, the following features are also specifically provided:

[0051] The heat transfer mechanism also includes an adapter frame 41 fixedly disposed in the heat collecting tube 40, an adapter shaft 43 rotatably disposed on the adapter frame 41, and a second impeller 42 coaxially fixedly disposed on the adapter shaft 43. The adapter shaft 43 is connected to the rotating bracket 31 via a pulley.

[0052] When the rotating bracket 31 rotates, the rotating bracket 31 drives the adapter shaft 43 to rotate, and the rotation of the adapter shaft 43 drives the second impeller 42 to rotate. The rotation of the second impeller 42 causes the heat in the heat collecting tube 40 to be blown into the heat conducting tube 45 and then into the heat releasing tube 44. The rotation of the second impeller 42 allows the heat to enter the heat releasing tube 44 faster.

[0053] The working principle of the device is as follows: liquid flows into the liquid inlet pipe 6 through the water delivery pipe seat 21. When the liquid flows from the liquid inlet pipe 6 into the transfer pipe 4, the liquid flow drives the first impeller 27 to rotate. The rotation of the first impeller 27 drives the power shaft 28 to rotate. The power shaft 28 drives the first bevel gear 23 to rotate. The rotation of the first bevel gear 23 drives the second bevel gear 24 to rotate. The rotation of the second bevel gear 24 drives the receiving shaft 25 to rotate. The rotation of the receiving shaft 25 drives the worm 39 to rotate. The rotation of the worm 39 drives the worm wheel 33 to rotate. The rotation of the worm wheel 33 drives the rotating bracket 3 1 rotates, the rotating bracket 31 rotates to drive the residual gear ring 32 and the residual gear 30 to rotate simultaneously, the residual gear ring 32 and the residual gear 30 successively mesh with the power gear 35, causing the power gear 35 to reciprocate. When the power gear 35 reciprocates, during the forward rotation of the power gear 35, the rotation of the power gear 35 is transmitted to the transmission rod 16 through the first magnetic ring 36 and the second magnetic ring 18, and the rotation of the transmission rod 16 causes the snap ring 19 to rotate until the contact block 20 abuts against the stopper 38. At this time, the transmission rod 16 has driven the cleaning brush 17 to swing against the filter plate 7 is cleaned once. At this time, if the power gear 35 continues to rotate, the first magnetic ring 36 will also continue to rotate. However, since the first magnetic ring 36 and the second magnetic ring 18 are connected by magnetic force, the continued rotation of the first magnetic ring 36 will not drive the second magnetic ring 18 to rotate, thereby preventing the power gear 35 from driving the transmission rod 16 to rotate excessively, causing the cleaning brush 17 to collide with the first partition 11 or the second partition 14. Similarly, when the power gear 35 reverses, the above structure will also prevent the cleaning brush 17 from colliding with the first partition 11 or the second partition 14. A collision occurs, and the setting of the contact block 20 and the stop block 38 can make the transmission rod 16 rotate forward and reverse at the same angle each time, so that the transmission rod 16 drives the cleaning brush 17 to continuously clean the filter plate 7, and when the rotating bracket 31 rotates, the rotating bracket 31 drives the adapter shaft 43 to rotate, and the rotation of the adapter shaft 43 drives the second impeller 42 to rotate. The rotation of the second impeller 42 causes the heat in the heat collecting tube 40 to be blown into the heat conducting tube 45 and then into the heat releasing tube 44. The rotation of the second impeller 42 allows the heat to enter the heat releasing tube 44 faster.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
