Abstract
Description
Technical Field
[0001] This invention relates to the field of air drying equipment technology, and specifically to a refrigerated air dryer. Background Technology
[0002] An air drying device is a mechanical device that uses heating to vaporize and release the moisture in a material in order to obtain a solid material with a specified moisture content.
[0003] Chinese patent CN220257629U discloses an adsorption-type air dryer, including a support frame and a buffer mechanism. Two drying towers are symmetrically and fixedly connected to the upper end of the support frame. An air inlet pipe is fixedly connected to the lower end of both drying towers, and an air outlet pipe is fixedly connected to the upper end of both drying towers. A processing box is fixedly connected to the upper end of the air outlet pipe. An activated carbon filter is slidably connected to the inner wall of the processing box. A fixing block is fixedly connected to the right side of the processing box, and a groove is formed on the right side of the fixing block. However, this device still has the following problems during use:
[0004] The air entering the air dryer is transported to the drying tower through a shared air inlet pipe, where the gas is processed. This may cause gas crosstalk, resulting in a reduction in cooling efficiency.
[0005] Based on this, the present invention designs a refrigerated air dryer to solve the above problems. Summary of the Invention
[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a refrigerated air dryer.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A refrigerated air dryer includes a cooling cylinder, an air outlet pipe, a reheating system, and an evaporation system. An air inlet is provided on the lower right side of the outer end of the cooling cylinder, and an air outlet pipe is fixedly installed on the upper end of the cooling cylinder. The interior of the cooling cylinder is equipped with a reheating system for pre-treating the air that just enters the cooling cylinder and for reheating the gas cooled by the evaporation system.
[0009] The reheating system includes baffle rings and reheating heating tubes. Multiple baffle rings are fixedly installed on the inner wall of the cooling cylinder. Multiple vent holes are provided on the outer ring of the baffle rings. Multiple reheating heating tubes are fixedly installed on the right side of the inside of the cooling cylinder, and the upper and lower ends of the reheating heating tubes are fixedly installed on the right side of the upper and lower baffle rings. The diameter of the vent holes on the baffle rings between the uppermost and lowermost baffle rings is larger than that on the vent holes on the uppermost and lowermost baffle rings.
[0010] The cooling cylinder is also equipped with an evaporation system for evaporating and cooling air, and the evaporation system is located inside the reheat system;
[0011] Furthermore, the reheating system also includes baffles. A baffle that is placed vertically and horizontally is fixedly installed at the middle of the inner top of the cooling cylinder, and baffles that are placed vertically and horizontally are also symmetrically fixedly installed on the front and rear sides between adjacent baffle rings.
[0012] Furthermore, the baffle is made of heat-insulating material;
[0013] Furthermore, a through groove is provided on the baffle plate between the topmost baffle ring and the adjacent baffle ring below it;
[0014] Furthermore, the retaining rings are evenly distributed in a linear array along the height direction inside the cooling cylinder;
[0015] Furthermore, the evaporation system includes a fixed cylinder, an evaporator core connecting pipe, a drain pipe, and an evaporator core. The fixed cylinder is fixedly installed on the inner ring of multiple retaining rings. An evaporation system inlet is located on the lower left side of the outer end of the fixed cylinder. An evaporation system outlet is located on the upper left side of the fixed cylinder. The upper ends of the evaporator core connecting pipe and the drain pipe are fixedly installed on the bottom end of the fixed cylinder and communicate with the evaporator core. The lower ends of the evaporator core connecting pipe and the drain pipe pass through the bottom of the cooling cylinder. The evaporator core is fixedly installed inside the fixed cylinder.
[0016] Furthermore, the fixed cylinder is made of heat-insulating material;
[0017] Furthermore, the evaporation core can be a plate cooler;
[0018] Furthermore, the vents are evenly distributed in a circular array at equal intervals on the outer ring of the retaining ring.
[0019] Compared with the prior art, the beneficial effects of this invention are as follows: Air enters the interior right side of the cooling cylinder through the air inlet. Due to the obstruction of the baffle, the air can only flow upward through the vent. When it flows to the through groove set on the baffle between the top baffle and the adjacent lower baffle, the air will flow to the left and enter the gas flow area. Then it flows downward and enters the interior of the evaporation system. Subsequently, the evaporation system operates to evaporate and cool the gas that has entered the evaporation system. The cooled air is then discharged through the evaporation system. The cooled gas then flows downward through the vent on the baffle and flows downward from the left side of the bottom baffle. The gas then flows through the vent and flows into the pretreatment heating area from the right side of the bottom baffle. Subsequently, the reheating heating tube operates to heat and reheat the cooled gas. The gas flows upward and is finally discharged through the air outlet pipe, completing one air compression, cooling and drying process. By setting baffles to separate the interior of the cooling cylinder, gas flow between the gas flow area and the pretreatment heating area is effectively isolated, improving the efficiency of air drying and cooling. Furthermore, by placing the evaporation system inlet in the gas flow area, the gas after evaporation and cooling is heated, further enhancing the air drying effect of the device.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A type of refrigerated air dryer includes a cooling cylinder (1), an air outlet pipe (3), a reheating system (4), and an evaporation system (5). An air inlet (2) is provided on the lower right side of the outer end of the cooling cylinder (1), and an air outlet pipe (3) is fixedly installed on the upper end of the cooling cylinder (1). The interior of the cooling cylinder (1) is equipped with a reheating system (4) for pre-treating the air that has just entered the cooling cylinder (1) and for reheating the gas that has been cooled by the evaporation system (5).
[0034] The reheating system (4) includes a baffle ring (41), a reheating heating tube (43), and a baffle plate (44). Multiple baffle rings (41) are fixedly installed on the inner wall of the cooling cylinder (1). The baffle rings (41) are evenly distributed in a linear array along the height direction inside the cooling cylinder (1). Multiple vent holes (42) are provided on the outer ring of the baffle ring (41). The vent holes (42) are evenly distributed in a circular array along the outer ring of the baffle ring (41). A baffle plate (44) is fixedly installed in a vertically horizontal position at the middle of the inner top of the cooling cylinder (1). Baffle plates (44) are also symmetrically fixed on the front and rear sides between two adjacent baffle rings (41). The baffle plate (44) between the topmost baffle ring (41) and the lower adjacent baffle ring (41) is provided with a passage. The baffle (44) divides the interior of the cooling cylinder (1) into two parts, left and right, and is used to isolate the gas flow between the two parts. The left half of the baffle (44) is set as a gas flow area, and the right half of the baffle (44) is set as a pretreatment heating area. The baffle (44) is made of heat-insulating material. Multiple reheating tubes (43) are fixedly installed on the right side of the interior of the cooling cylinder (1), and the upper and lower ends of the reheating tubes (43) are fixedly installed on the right side of the upper and lower baffle rings (41). The diameter of the vent hole (42) on the baffle ring (41) between the uppermost baffle ring (41) and the lowermost baffle ring (41) is larger than that on the uppermost baffle ring (41) and the lowermost baffle ring (41), which speeds up the air flow.
[0035] The cooling cylinder (1) is also equipped with an evaporation system (5) for evaporating and cooling air, and the evaporation system (5) is located inside the reheat system (4).
[0036] In this invention, air enters the inside right side of the cooling cylinder (1) through the air inlet (2). Due to the obstruction of the baffle (44), the air can only flow upward through the vent (42). When it flows to the through groove provided on the baffle (44) between the top baffle ring (41) and the lower adjacent baffle ring (41), the air will flow to the left and enter the gas flow area. Then it flows downward and enters the interior of the evaporation system (5). Subsequently, the evaporation system (5) works to evaporate and cool the gas that has entered the interior of the evaporation system (5). After cooling, the air is discharged through the evaporation system (5). Then, the cooled gas flows downward through the vent (42) on the baffle ring (41) and flows downward from the left side of the bottom baffle ring (41). The gas then flows through the vent (42) and flows into the pretreatment heating area from the right side of the bottom baffle ring (41). Then, the reheating heating pipe (43) works to heat and reheat the cooled gas. The gas flows upward and is finally discharged through the air outlet pipe (3), completing one air compression, cooling and drying process. By setting baffles (44) to separate the interior of the cooling cylinder (1), the gas flow area and the pretreatment heating area are effectively isolated from gas crosstalk, improving the efficiency of air drying and cooling. Furthermore, by setting the evaporation system inlet (52) in the gas flow area, the gas cooled by evaporation is heated, further enhancing the air drying effect of the device.
[0037] Example 2: In some embodiments, such as Figures 4-8 As shown, in a preferred embodiment of the present invention, the evaporation system (5) includes a fixed cylinder (51), an evaporation core connecting pipe (54), a drain pipe (55), and an evaporation core (56). The fixed cylinder (51) is fixedly installed on the inner ring of a plurality of retaining rings (41). An evaporation system inlet (52) is provided on the lower left side of the outer end of the fixed cylinder (51). An evaporation system outlet (53) is provided on the upper left side of the fixed cylinder (51). The upper ends of the evaporation core connecting pipe (54) and the drain pipe (55) are fixedly installed on the bottom end of the fixed cylinder (51) and communicate with the evaporation core (56). The lower ends of the evaporation core connecting pipe (54) and the drain pipe (55) pass through the bottom of the cooling cylinder (1). The evaporation core (56) is fixedly installed inside the fixed cylinder (51). The fixed cylinder (51) is made of heat-insulating material.
[0038] In this invention, when air flows to the evaporation system inlet (52), it enters the interior of the fixed cylinder (51) through the evaporation system inlet (52). Then, the evaporation core (56) works to evaporate and cool the air. After evaporation and cooling are completed, the gas is discharged through the evaporation system outlet (53). The drain pipe (55) can discharge the water generated during evaporation into the fixed cylinder (51).
[0039] Example 3: In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the evaporator core (56) can be a plate cooler, which is composed of thin metal plates pressed with a corrugated shape. Narrow and tortuous channels are formed between two adjacent plates, through which the hot and cold fluids flow only once each. The intermediate insulating plates act as fluid separators, ensuring that the circulating cold air and hot air achieve effective heat exchange through these insulating plates.
[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
