Description

Technical Field

[0001] This invention relates to the field of refrigerated dryer technology, and particularly to a high-temperature air-cooled refrigerated dryer. Background Technology

[0002] Refrigerated air dryers utilize physical principles to freeze the moisture in compressed air below the dew point, causing it to be released from the air. Due to the freezing point of water, theoretically, their dew point temperature can be close to zero degrees Celsius.

[0003] A search revealed a patent document with authorization announcement number CN211977397U, which discloses a high-temperature air-cooled refrigerated dryer. This dryer includes a main body, an exhaust fan, and a motor. A first fixed frame is fixedly connected to the top of the main body, and a vent pipe is fixedly connected to the inner wall of the first fixed frame. A dust removal mechanism is installed inside the vent pipe, and a filter screen is installed inside the first fixed frame. The exhaust fan is fixedly connected to the end of the vent pipe furthest from the filter screen. The dryer features a fixed rotating shaft and a moving block. Rotation of the fixed rotating shaft allows the moving block to move on the surface of the shaft, thereby moving a fixed base plate out of the base. This facilitates the overall movement and transport of the refrigerated dryer. The exhaust fan effectively reduces the high temperature generated inside the dryer during operation, significantly extending its service life.

[0004] However, it still has some shortcomings in use. It draws outside air into the main body of the refrigerated dryer through an exhaust fan, but it cannot cool the air drawn in by the exhaust fan. It only cools the air by drawing in air at ambient temperature. When the weather outside is hot and the outside air temperature is high, its cooling effect is relatively weak.

[0005] Based on this, the present invention designs a high-temperature air-cooled refrigerated dryer to solve the above problems. Summary of the Invention

[0006] Technical problems to be solved: To address the shortcomings of existing technologies, this invention provides a high-temperature air-cooled refrigerated dryer, which solves the problem mentioned in the background art where external air is drawn into the refrigerated dryer body by an exhaust fan, but this fan cannot cool the air drawn in; it merely cools the air at ambient temperature by drawing it into the refrigerated dryer body. When the external weather is hot and the external air temperature is high, the cooling effect is relatively weak.

[0007] Technical solution: To achieve the above objectives, the present invention provides the following technical solution: A high-temperature air-cooled refrigerated dryer includes a dryer body and an air duct. The air duct blows air into the dryer body to cool it. A cooling mechanism is installed on the air duct to cool the air flowing inside the air duct. The cooling mechanism includes a cooling shell, a cooling pipe, a mounting base, a cooling plate, and a cooling clamp. The cooling shell is installed at the upper end of the air duct and provides low-temperature coolant to the cooling pipe. The cooling pipe is installed inside the cooling shell and extends into the cooling chamber of the air duct. The mounting base is installed inside the cooling chamber and fixes the cooling plate and the cooling clamp. The cooling plate and the cooling clamp are assembled and fixedly installed on the mounting base. The cooling pipe is coiled inside the cooling plate and the cooling clamp, and cools the air in the cooling chamber through the cooling plate and the cooling clamp to improve the cooling efficiency of the air duct on the dryer body.

[0008] In one possible implementation, the cooling plate has slots, mounting slots, a first semi-circular groove, and a first ventilation hole, wherein: a plurality of slots are provided and are formed on the cooling plate, and the slots are used to accommodate the cooling plate; a mounting groove is formed between two slots, and the length of the mounting groove is less than that of the slot; a first semi-circular groove is formed in the slots and the mounting groove, and the first semi-circular groove is used to accommodate the cooling pipe; a plurality of first ventilation holes are provided and are evenly formed on the cooling plate, and the first ventilation holes are used to improve the cooling efficiency of the air in the cooling cavity.

[0009] In one possible implementation, the cooling plate has several sections inserted into the slots. The cooling plate has a second semi-circular groove, a second ventilation hole, and a fixing groove. The second semi-circular groove is located on both sides of the cooling plate and together with the first semi-circular groove forms a channel for accommodating the cooling pipe. The second ventilation hole has several sections evenly distributed on the cooling plate and is used to improve the cooling efficiency of the air in the cooling chamber. The fixing groove is located on the side of the cooling plate.

[0010] In one possible implementation, the cooling plate is provided with a fixing mechanism for fixing the cooling plate. The fixing mechanism includes a telescopic cavity, a driving cavity, a telescopic plate, and a fixing block, wherein: the telescopic cavity is formed inside the cooling plate and communicates perpendicularly with the driving cavity, and the driving cavity extends outside the cooling plate; the telescopic plate is slidably connected inside the telescopic cavity and is used to drive the fixing block; the fixing block is fixedly mounted on the telescopic plate and extends out of the driving cavity, and the fixing block corresponds to and matches the fixing groove; the telescopic plate drives the fixing block to insert into the fixing groove to fix the cooling plate to the cooling plate.

[0011] In one possible implementation, the fixing mechanism further includes a limiting rod, a spring, a driving block, a pressing block, and an inclined surface, wherein: one end of the limiting rod is fixedly mounted on the telescopic plate, and the other end is inserted into the cooling plate; the spring is sleeved on the limiting rod and located between the telescopic plate and the inner wall of the telescopic cavity; the driving block is slidably connected in the driving cavity, and both the driving block and the limiting rod have inclined surfaces, the driving block driving the limiting rod to slide along the telescopic cavity through the inclined surfaces; the pressing block is fixedly mounted on the end of the driving block away from the inclined surfaces and is slidably connected in the driving cavity.

[0012] In one possible implementation, the mounting base is provided with a mounting cavity, mounting blocks, an arc-shaped surface, and a through hole, wherein: the mounting cavity is formed on the bottom surface of the mounting base and matches the cooling plate; a plurality of mounting blocks are provided and installed in the mounting cavity, and the mounting blocks match the mounting groove; the arc-shaped surface is formed on the mounting blocks and together with the first semi-circular groove forms a channel for accommodating the cooling pipe; the through hole is formed on the mounting base, and the cooling plate has a connecting hole corresponding to and matching the through hole, and bolts pass through the through hole and the connecting hole to fix the cooling plate and the cooling plate to the mounting base.

[0013] In one possible implementation, the cooling pipe passes through the cooling shell and the mounting base and enters the channel formed by the cooling plate and the cooling card. The cooling pipe cools the air in the cooling chamber through the cooling plate and the cooling card. The cooling pipe is connected to an inlet valve and an outlet valve, which are located in the coolant inside the cooling shell.

[0014] In one possible implementation, a cooler for cooling the coolant is installed on the inner wall of the cooling shell, and an inlet for adding the coolant is provided at the top.

[0015] In one possible implementation, the air duct has an air inlet and an air outlet communicating with the cooling chamber. The air inlet is equipped with a fan and a filter screen. The fan is used to draw in outside air, and the filter screen is used to filter the air.

[0016] In one possible implementation, the dryer body is mounted on a moving mechanism, and a temperature sensor for detecting the internal temperature of the dryer body is installed on the dryer body.

[0017] Beneficial effects: In this invention, an air duct introduces outside air into the dryer body for cooling. As the outside air flows through the air duct, it passes through a cooling chamber where the cooling mechanism further cools it, preventing insufficient cooling of the dryer body when the outside air temperature is high, which would otherwise be ineffective. Low-temperature coolant flows through the cooling pipes in the cooling mechanism. This coolant exchanges heat with the outside air via cooling plates and cooling plates, causing a rapid decrease in the outside air temperature and effectively improving the subsequent cooling efficiency of the dryer body. The cooling plates and cooling plates fix the cooling pipes and are also fixed to the inner wall of the cooling chamber via mounting brackets, ensuring stable heat exchange between the low-temperature coolant in the cooling pipes and the outside air, thus fully cooling the outside air.

Implementation

[0020] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0021] Please refer to a high-temperature air-cooled refrigerated dryer. Figures 1-7 The system includes a dryer body 1 and a duct 3. The duct 3 blows air into the dryer body 1 to cool it down. A cooling mechanism is installed on the duct 3 to cool the air flowing inside the duct. The cooling mechanism includes a cooling shell 4, a cooling pipe 5, a mounting base 6, a cooling plate 7, and a cooling clamping plate 8. The cooling shell 4 is installed at the upper end of the duct 3 and is used to provide low-temperature coolant to the cooling pipe 5. The cooling pipe 5 is installed inside the cooling shell 4 and extends into the cooling chamber 32 of the duct 3. The mounting base 6 is installed inside the cooling chamber 32 and is used to fix the cooling plate 7 and the cooling clamping plate 8. The cooling plate 7 and the cooling clamping plate 8 are assembled and fixedly installed on the mounting base 6. The cooling pipe 5 is coiled inside the cooling plate 7 and the cooling clamping plate 8. The cooling pipe 5 cools the air in the cooling chamber 32 through the cooling plate 7 and the cooling clamping plate 8 to improve the cooling efficiency of the duct 3 on the dryer body 1.

[0022] Through the above technical solution, the air duct 3 of this invention introduces outside air into the dryer body 1 for cooling. During the airflow through the air duct 3, the outside air passes through the cooling chamber 32, where the cooling mechanism cools the air, preventing weak cooling of the dryer body 1 when the outside weather is hot. Low-temperature coolant flows through the cooling pipe 5 in the cooling mechanism. This coolant exchanges heat with the outside air through the cooling plate 7 and cooling plate 8, causing a rapid decrease in the outside air temperature and effectively improving the subsequent cooling efficiency of the dryer body 1. The cooling plate 7 and cooling plate 8 fix the cooling pipe 5 and are also fixed to the inner wall of the cooling chamber 32 by the mounting base 6, ensuring stable heat exchange between the low-temperature coolant in the cooling pipe 5 and the outside air, thus fully cooling the outside air.

[0023] In some examples, refer to Figure 1-7 As shown, the dryer body 1 is mounted on the moving mechanism 2, and a temperature sensor 11 for detecting the temperature inside the dryer body 1 is installed on the dryer body 1.

[0024] Through the above technical solution, the dryer body 1 can be moved by the moving mechanism 2 in this invention. When the temperature sensor 11 detects that the temperature inside the dryer body 1 is too high, the air duct 3 passes air into the dryer body 1 to cool it down.

[0025] In some examples, refer to Figure 1-7 As shown, the air duct 3 has an air inlet 31 and an air outlet 33 that are connected to the cooling chamber 32. The air inlet 31 is equipped with a fan 34 and a filter screen 35. The fan 34 is used to draw in outside air, and the filter screen 35 is used to filter the air. The inner wall of the cooling shell 4 is equipped with a cooler 41 for cooling the coolant, and the top has an inlet 42 for adding coolant.

[0026] Through the above technical solution, in this invention, the fan 34 draws outside air into the cooling chamber 32 through the air inlet 31, the cooling mechanism cools the outside air, and then the low-temperature air enters the dryer body 1 through the exhaust port 33 for further cooling; the filter 35 can filter the air entering the air inlet 31 to reduce dust intake; the cooler 41 can cool the coolant to improve the cooling efficiency of the outside air; and the liquid inlet 42 facilitates the addition of coolant.

[0027] In some examples, refer to Figure 1-7As shown, the cooling plate 7 has slots 71, mounting slots 72, first semi-circular slots 73, and first ventilation holes 74.

[0028] In some examples, refer to Figure 1-7 As shown, the cooling plate 8 has several slots inserted into the slots 71. The cooling plate 8 has a second semi-circular groove 81, a second ventilation hole 82, and a fixing groove 83. The second semi-circular groove 81 is located on both sides of the cooling plate 8 and together with the first semi-circular groove 73, forms a channel for accommodating the cooling pipe 5. The second ventilation hole 82 is located on the cooling plate 8 and is evenly distributed. The second ventilation hole 82 is used to improve the cooling efficiency of the air in the cooling chamber 32. The fixing groove 83 is located on the side of the cooling plate 8.

[0029] Through the above technical solution, in this invention, the cooling plate 8 is slidably inserted into the slot 71 inside the cooling plate 7, and the first semi-circular slot 73 and the second semi-circular slot 81 form a channel for the cooling pipe 5 to pass through. Both the cooling plate 7 and the cooling plate 8 are made of thermally conductive materials. The cooling pipe 5 exchanges heat with the outside air through the cooling plate 7 and the cooling plate 8, which effectively cools the outside air. The setting of the first ventilation hole 74 and the second ventilation hole 82 improves the efficiency of the cooling pipe 5 exchanging heat with the outside air through the cooling plate 7 and the cooling plate 8, which is beneficial for cooling the outside air.

[0030] In some examples, refer to Figure 1-7 As shown, the cooling plate 7 is provided with a fixing mechanism 9 for fixing the cooling plate 8. The fixing mechanism 9 includes a telescopic cavity 91, a driving cavity 92, a telescopic plate 93, and a fixing block 94. The telescopic cavity 91 is opened in the cooling plate 7 and is perpendicular to the driving cavity 92. The driving cavity 92 extends outside the cooling plate 7. The telescopic plate 93 is slidably connected in the telescopic cavity 91 and is used to drive the fixing block 94. The fixing block 94 is fixedly installed on the telescopic plate 93 and extends out of the driving cavity 92. The fixing block 94 corresponds to and matches the fixing groove 83. The telescopic plate 93 drives the fixing block 94 to insert into the fixing groove 83 to fix the cooling plate 8 to the cooling plate 7.

[0031] In some examples, refer to Figure 1-7As shown, the fixing mechanism 9 also includes a limiting rod 95, a spring 96, a driving block 97, a pressing block 98, and an inclined surface 99. Specifically: one end of the limiting rod 95 is fixedly mounted on the telescopic plate 93, and the other end is inserted into the cooling plate 7; the spring 96 is sleeved on the limiting rod 95 and located between the telescopic plate 93 and the inner wall of the telescopic cavity 91; the driving block 97 is slidably connected within the driving cavity 92, and both the driving block 97 and the limiting rod 95 have inclined surfaces 99. The driving block 97 drives the limiting rod 95 to slide along the telescopic cavity 91 via the inclined surfaces 99; the pressing block 98 is fixedly mounted on the end of the driving block 97 away from the inclined surface 99 and is slidably connected within the driving cavity 92.

[0032] Through the above technical solution, in this invention, the spring 96 drives the fixing block 94 to insert into the fixing groove 83 via the telescopic plate 93 to fix the cooling plate 8 onto the cooling plate 7; the pressing block 98 drives the limiting rod 95 to slide along the telescopic cavity 91 via the driving block 97, and the limiting rod 95 drives the fixing block 94 to disengage from the fixing groove 83 via the telescopic plate 93, so as to remove the cooling plate 8 from the cooling plate 7, while compressing the spring 96; the driving block 97 drives the limiting rod 95 to slide along the telescopic cavity 91 via the inclined surface 99, so as to remove the cooling plate 8 from the cooling plate 7 subsequently.

[0033] In some examples, refer to Figure 1-7 As shown, the mounting base 6 is provided with a mounting cavity 61, a mounting block 62, an arc-shaped surface 63, and a through hole 64. The mounting cavity 61 is opened on the bottom surface of the mounting base 6 and matches the cooling plate 7. Several mounting blocks 62 are provided and installed in the mounting cavity 61, and the mounting blocks 62 match the mounting groove 72. The arc-shaped surface 63 is opened on the mounting block 62 and together with the first semi-circular groove 73, forms a channel for accommodating the cooling pipe 5. The through hole 64 is opened on the mounting base 6, and the cooling plate 7 is provided with a connecting hole corresponding to and matching the through hole 64. Bolts pass through the through hole 64 and the connecting hole to fix the cooling plate 7 and the cooling plate 8 to the mounting base 6.

[0034] Through the above technical solution, in this invention, the mounting block 62 is inserted into the mounting groove 72, and the arc-shaped surface 63 and the first semi-circular groove 73 together form a channel for accommodating the cooling pipe 5; the setting of the mounting cavity 61 facilitates the insertion of the cooling plate 7 and the cooling plate 8 into the mounting base 6, and facilitates the subsequent screws to pass through the through hole 64 and the connecting hole to fix the cooling plate 7 and the cooling plate 8 onto the mounting base 6.

[0035] In some examples, refer to Figure 1-7 As shown, the cooling pipe 5 passes through the cooling shell 4 and the mounting base 6 and enters the channel formed by the cooling plate 7 and the cooling plate 8. The cooling pipe 5 cools the air in the cooling chamber 32 through the cooling plate 7 and the cooling plate 8. The cooling pipe 5 is connected to the liquid inlet valve 51 and the liquid outlet valve 52, which are located in the coolant inside the cooling shell 4.

[0036] Through the above technical solution, in this invention, the inlet valve 51 controls the low-temperature coolant to enter the cooling pipe 5, so that the cooling pipe 5 can exchange heat with the outside air through the cooling plate 7 and the cooling plate 8; the outlet valve 52 controls the coolant heated in the cooling pipe 5 to enter the cooling shell 4 for cooling.

[0037] The working principle of this invention is as follows: First, the cooling pipe 5 is placed into the first semi-circular groove 73. Then, the cooling plate 8 is slidably inserted into the slot 71 in the cooling plate 7. Then, the spring 96 drives the fixing block 94 to be inserted into the fixing groove 83 through the telescopic plate 93, fixing the cooling plate 8 onto the cooling plate 7. The pressing block 98 drives the driving block 97 to slide along the driving cavity 92. The driving block 97 drives the limiting rod 95 to slide along the telescopic cavity 91 through the inclined surface 99. The limiting rod 95 drives the fixing block 94 to disengage from the fixing groove 83 through the telescopic plate 93. Then, the cooling plate 8 is removed from the cooling plate 7, and the cooling pipe 5 can be disassembled from the cooling plate 7. The cooling plate 7 and the cooling plate 8 are inserted into the mounting cavity 61, and the mounting block 62 is inserted into the mounting groove 72. Then, the cooling plate 7 and the cooling plate 8 are fixed onto the mounting base 6 by passing the screw through the through hole 64 and the connecting hole.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
