Description

Technical Field

[0001] The utility model relates to the field of evaporative condensers, in particular to an adjustable evaporative condenser. Background Art

[0002] In production and life, evaporative condensers are needed because they can quickly dissipate the heat in the refrigerant, convert the refrigerant from a gaseous state to a liquid state, and thus realize the continuous progress of the refrigeration cycle. In addition, by combining water cooling and air cooling, the evaporative condenser improves the heat dissipation efficiency and can more effectively reduce the temperature and pressure of the refrigerant compared with traditional condensers.

[0003] Currently, an evaporative condenser generally includes a condensing coil, a spraying device, a fan, a water tank, a housing, a water pump, etc. The condensing coil is arranged at the top inside the housing, the spraying device is arranged above the condensing coil and is connected to the water pump, the fan is arranged on the top of the housing, and the water tank is arranged below the housing. The condensing coils are closely arranged to increase the contact area with water and air. The spraying device evenly sprays water onto the coils, and the fan generates a strong air flow to quickly evaporate the water and take away a large amount of heat. The water in the water tank circulates continuously through the water pump, and the water baffle effectively reduces the splashing and loss of water to ensure the stable operation of the system. For the specific structure of the evaporative condenser, reference can also be made to a Chinese patent with the publication number CN116020156A, which discloses a machine shell provided with a water collecting tank. A filter plate is arranged in the water collecting tank along the height direction, and the filter plate divides the water collecting tank into two parts. A lower threaded rod is rotatably connected to the water collecting tank along the length direction of the machine shell, and the lower threaded rod is threadedly connected to the filter plate. A guide plate is arranged at the upper end of the water collecting tank, and the height of the guide plate gradually decreases along the direction away from the circulation pipe. The lowest part of the guide plate is at the same height as the filter plate. The filter plate is hollow and is slidably connected with an inner plate along the height direction, and through holes corresponding to the filter holes of the filter plate are opened. A first elastic member is connected between the filter plate and the inner plate. In the natural state of the first elastic member, the upper end of the inner plate extends outside the filter plate and the through holes are communicated with the corresponding filter holes.

[0004] As can be seen from the above, an air inlet hole is provided between the housing and the water tank or the water collecting tank so that under the action of the fan, external gas can flow into the housing through the air inlet hole, thereby realizing the air cooling of the condensing pipe and forcing the coolant to contact the condensing pipe more dispersedly. However, there is a problem that after the dust and impurities carried by the gas come into contact with the cooling water, they will drop with the cooling water and remain in the water tank or the water collecting tank. Over time, the impurities float on the liquid surface and the dust forms a silt layer in the water tank or the water collecting tank, blocking the water flow channels and even flowing into the water pump with the gas, resulting in damage to the water pump.

[0030] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] The following will be further described in conjunction with the drawings and specific embodiments: Embodiment

[0032] In order to clean the accumulated silt and impurities in the water tank or water collecting tank of the evaporative condenser, in this embodiment, the water tank or water collecting tank is improved on the basis of the existing evaporative condenser, so that the staff can clean the inside of the water tank or water collecting tank. The specific technical solution is as follows.

[0033] As Figure 1 shown, here the evaporative condenser is divided into two parts: the evaporative condenser main body 1 and the water collecting tank 2. The water collecting tank 2 is arranged below the evaporative condenser main body 1, and cooling water is stored inside. At the same time, a water pump is arranged on the side of the water collecting tank 2. The input end of the water pump is communicated with the water collecting tank 2, and the output end is connected to the top of the evaporative condenser main body 1 and is communicated with the spraying device located in the evaporative condenser main body 1. In addition, a fan is arranged on the top of the evaporative condenser main body 1, and a condensing coil is arranged below the spraying device on the inner top. The condensing coil is connected to the compressor, and the compressor forces the refrigerant to move in the condensing coil. Since the evaporative condenser is a prior art, the evaporative condenser main body 1 will not be described in detail here.

[0034] As shown Figure 4 in the figure, the water collecting tank 2 is also a prior art, but there are some improvements compared with the prior art. Specifically, the water collecting tank 2 includes a frame body, side plates 24 and end plates 23. The side plates 24 and end plates 23 are both arranged on the frame body. Therefore, one end and the upper side of the water collecting tank 2 are both arranged to be open. The upper side opening is mainly for receiving the return water. In order to make the water collecting tank 2 closed to store the cooling water, a sealing groove 25 is arranged at the opening end of the frame body, that is, a sealing layer is arranged in the sealing groove 25, and the edge of the detachable plate 26 extends into the sealing groove 25. The limiting mechanism 3 is adjustably arranged on the frame body and is arranged to press against the detachable plate 26.

[0035] As shown Figure 2 in the figure, in order to avoid impurities from entering the water collecting tank 2, a supporting frame 22 is arranged on the top of the frame body, and a filter screen 21 is laid on the supporting frame 22 by bolts. Under the action of the filter screen 21, some large-sized impurities can be blocked.

[0036] As shown Figure 3 , Figure 8 , Figure 9 in the figure, in order to clean the impurities and silt accumulated in the water collecting tank 2, a first cleaning component 4 is arranged on the inner side of the water collecting tank 2. The first cleaning component 4 includes an annular belt 46, a first end shaft 41 and a second end shaft 42. The annular belt 46 is attached to the bottom of the water collecting tank 2 and the end is close to the end of the water collecting tank 2. The first end shaft 41 and the second end shaft 42 respectively penetrate through both ends of the annular belt 46 and the ends penetrate through the frame body. Therefore, when controlling the rotation of the end shaft, the annular belt 46 rotates. Since the annular belt 46 is laid flat on the bottom of the water collecting tank 2, the falling impurities and silt are mainly accumulated on the annular belt 46. When the annular belt 46 rotates, the impurities and silt can be controlled to move, providing support for outputting the water collecting tank 2, and thus the cleaning of the water collecting tank 2 can be realized. In order to avoid water leakage, pressing ring plates 44 and sealing gaskets 45 are sleeved on the protruding ends of the first end shaft 41 and the second end shaft 42 from the frame body end. A runner 43 is also sleeved on the end of the first end shaft 41 or the second end shaft 42. The sealing gasket 45 is arranged on the side of the pressing ring plate 44 close to the water collecting tank 2. The pressing ring plate 44 is connected to the water collecting tank 2 by bolts. Therefore, the sealing gasket 45 can be forced to deform under the action of the pressing ring plate 44, thereby blocking the contact surface between the end shaft and the frame body and realizing the sealing of the water collecting tank 2. When it is necessary to clean the water collecting tank 2, the pressure on the sealing gasket 45 is removed to make it recover its deformation, thereby reducing the resistance of the end shaft rotation. When the detachable plate 26 is disassembled, the end of the water collecting tank 2 is made smooth so that the silt and impurities can be output.

[0037] As shown Figure 5 , Figure 6 , Figure 7As shown in the figure, in order to facilitate the removal of silt and impurities from the water collecting tank 2, the limiting mechanism 3 includes a bracket 31, two snap plates 33 and multiple pressing plates 32. The bracket 31 is arranged in a U-shaped structure, and a snap groove 312 is provided at the end. The snap plates 33 are connected to the frame by bolts and are arranged along the height direction of the frame. The two snap plates 33 respectively pass through the snap grooves 312 at both ends of the bracket 31. Therefore, the bracket 31 is stably and movably connected to the snap plates 33, and thus the height of the bracket 31 can be adjusted according to requirements to realize the adjustment of the bracket 31, which provides convenience for disassembling the detachable plate 26 and cleaning impurities and silt. The height of the pressing plate 32 is less than or equal to the height of the detachable plate 26, and a plug shaft 321 is fixedly arranged on the side. A threaded rod 322 is arranged on the side of the pressing plate 32. The plug shaft 321 is inserted into the end of the threaded rod 322 through a bearing connection. The threaded rod 322 is threadedly passed through the threaded hole 311 of the bracket 31. By rotating the threaded rod 322, the movement of the pressing plate 32 can be controlled, and the detachable plate 26 can be pressed and stably arranged, realizing the closing of the water collecting tank 2. When it is necessary to clean the water collecting tank 2, rotate the threaded rod 322 in the reverse direction, and the restriction on the detachable plate 26 can be released, which provides convenience for the detachable plate 26 to be separated from the water collecting tank 2. Embodiment

[0038] As Figure 10 , Figure 11 As shown in the figure, on the basis of Embodiment 1, the second cleaning assembly 5 replaces the first cleaning assembly 4. The second cleaning assembly 5 includes a cleaning plate 51, a pulling loop rope 53 and two support frames 54. The two support frames 54 are arranged at both ends of the bottom of the water collecting tank 2, and two pulleys 55 are respectively arranged up and down on the support frames 54. The pulling loop rope 53 is sleeved on the pulleys 55, and the lower side is fixedly connected to the cleaning plate 51. Therefore, the staff can pull the pulling loop rope 53 to control the movement of the cleaning plate 51, providing support for cleaning the water collecting tank 2. The lower side of the cleaning plate 51 is attached to the bottom of the water collecting tank 2, and a sliding card slot 52 is provided. A sliding card plate 27 is fixedly arranged at the bottom of the water collecting tank 2. The sliding card plate 27 passes through the sliding card slot 52, enabling the cleaning plate 51 to be stably, movably and attached to the bottom of the water collecting tank 2, providing convenience for cleaning the silt at the bottom of the water collecting tank 2.
