Description

Technical Field

[0001] This invention relates to the field of R125 product manufacturing technology, specifically to a dryer for processing R125 products. Background Technology

[0002] R125 (pentafluoroethane) is a type of refrigerant, a hybrid (HFC) that does not damage the atmospheric ozone layer. R125 is an important component in blends of R404A, R407C, R410A, R417A, and R507. When mixed with R32, it forms R410a, a new type of refrigerant. Currently, R125 refrigerant is widely used in various air conditioners. During the production process of R125 refrigerant, a drying device is required to dry the refrigerant, thereby removing moisture and improving its performance and quality.

[0003] However, most existing dehydration and drying devices rely on desiccants for drying, which is a relatively simple method. After prolonged use, the effectiveness of the desiccant will gradually decrease, resulting in poor drying of the refrigerant and causing a large amount of insufficiently dried refrigerant to leak out, thus affecting the refrigerant's performance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dryer for processing R125 products, which has the advantages of good drying effect and a variety of drying methods. It solves the problem that most existing dehydration and drying devices rely on desiccants for drying, which is a relatively simple drying method. After long-term use, the effectiveness of the desiccant will continue to decline, resulting in poor drying effect on the refrigerant and causing a large amount of insufficiently dried refrigerant to flow out, thus affecting the refrigerant's performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dryer for processing R125 products, comprising a drying cylinder, wherein a drying mechanism is provided inside the drying cylinder;

[0006] The drying mechanism includes a mounting plate fixedly installed on the inner surface of the drying cylinder. A mounting block is fixedly installed on the upper surface of the mounting plate, and a centrifuge cylinder is rotatably installed on the upper surface of the mounting block.

[0007] Furthermore, an annular groove is formed on the inner surface of the drying cylinder, and a ring is fixedly installed on the outer surface of the centrifuge cylinder. The ring is located in the annular groove, and the outer surface of the ring is slidably connected to the inner surface of the annular groove.

[0008] Furthermore, the centrifuge tube has multiple liquid outlet holes on its side surface, and the spacing between any two adjacent liquid outlet holes is equal.

[0009] Furthermore, the mounting plate has multiple drainage holes on its surface, with equal spacing between adjacent drainage holes, and the diameter of each drainage hole is not less than one centimeter and not more than one and a half centimeters.

[0010] Furthermore, two liquid inlet pipes are fixedly installed on the upper surface of the drying cylinder, and the inner cavity of the liquid inlet pipes is connected to the inner cavity of the drying cylinder.

[0012] Furthermore, a fixing frame is fixedly installed on the outer surface of the motor, and the fixing frame is fixedly connected to the upper surface of the drying cylinder.

[0013] Furthermore, a protective cover is fixedly installed on the upper surface of the drying cylinder, and the motor is located inside the protective cover.

[0014] Furthermore, the left and right surfaces of the protective cover are provided with heat dissipation vents, the size of which is smaller than the surface area of ​​the left and right surfaces of the protective cover.

[0015] Furthermore, dustproof nets are fixedly installed on the left and right surfaces of the protective cover, on the side of the heat dissipation vent away from the motor, and the size of the dustproof nets is larger than the size of the heat dissipation vent.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] This dryer for processing R125 products consists of a centrifuge cylinder, a first filter sleeve, and a second filter sleeve inside the drying drum.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4This embodiment of a dryer for processing R125 products includes a drying cylinder 1. A drying mechanism is installed inside the drying cylinder 1. The drying mechanism includes a mounting plate 2 fixedly installed on the inner surface of the drying cylinder 1. Multiple leakage holes 15 are formed on the surface of the mounting plate 2, with equal spacing between adjacent holes 15. The diameter of each leakage hole 15 is no less than 1 cm and no more than 1.5 cm. A mounting block 3 is fixedly installed on the upper surface of the mounting plate 2. A centrifuge cylinder 4 is rotatably mounted on the upper surface of the mounting block 3. An annular groove 12 is formed on the inner surface of the drying cylinder 1. A circular ring 13 is fixedly installed on the outer surface of the centrifuge cylinder 4, located within the annular groove 12. The outer surface of the circular ring 13 is slidably connected to the inner surface of the annular groove 12, facilitating greater stability of the centrifuge cylinder 4 during rotation. Multiple liquid outlet holes 14 are formed on the side surface of the centrifuge cylinder 4. The spacing between two adjacent liquid outlet holes 14 is equal, which facilitates the refrigerant in the centrifuge cylinder 4 to be thrown into the drying cylinder 1. Two liquid inlet pipes 16 are fixedly installed on the upper surface of the drying cylinder 1. The inner cavity of the liquid inlet pipe 16 is connected to the inner cavity of the drying cylinder 1, which facilitates the injection of refrigerant into the drying cylinder 1. A guide cylinder 17 is fixedly installed on the upper surface of the inner cavity of the drying cylinder 1. The top diameter of the guide cylinder 17 is smaller than the bottom diameter of the guide cylinder 17. The bottom of the guide cylinder 17 is located inside the centrifuge cylinder 4, which facilitates the introduction of refrigerant into the centrifuge cylinder 4. A water filter sleeve 5 is fixedly installed on the side surface of the inner cavity of the centrifuge cylinder 4. A first filter sleeve 6 located below the mounting plate 2 is fixedly installed on the side surface of the inner cavity of the drying cylinder 1. A second filter sleeve 7 located below the first filter sleeve 6 is fixedly installed on the side surface of the inner cavity of the drying cylinder 1.

[0025] A motor 10 is fixedly installed on the upper surface of the drying cylinder 1. A rotating rod 11 extending into the drying cylinder 1 is fixedly installed at the output end of the motor 10. The end of the rotating rod 11 away from the motor 10 is fixedly connected to the lower surface of the inner cavity of the centrifuge cylinder 4. A fixing frame 18 is fixedly installed on the outer surface of the motor 10. The fixing frame 18 is fixedly connected to the upper surface of the drying cylinder 1, which facilitates the fixing of the motor 10 and helps to increase the stability of the motor 10 during operation. A protective cover 19 is fixedly installed on the upper surface of the drying cylinder 1. The motor 10 is located inside the protective cover 19, which facilitates the protection of the motor 10 and prevents the motor 10 from being damaged. Heat dissipation vents 20 are opened on the left and right surfaces of the protective cover 19. The size of the heat dissipation vents 20 is smaller than the surface area of ​​the left and right surfaces of the protective cover 19, which helps the motor 10 dissipate the heat generated during operation from the protective cover 19. Dustproof nets 21 are fixedly installed on the left and right surfaces of the protective cover 19 on the side of the heat dissipation vents 20 away from the motor 10. The size of the dustproof nets 21 is larger than the size of the heat dissipation vents 20, which helps to prevent dust from entering the protective cover 19.

[0026] It should be noted that, in order to facilitate the refrigerant to pass through the first filter sleeve 6 and the second filter sleeve 7, both the first filter sleeve 6 and the second filter sleeve 7 in this embodiment are made of woven mesh.

[0027] It should be noted that, in order to facilitate the support of the drying cylinder 1, three support legs are fixedly installed on the outer surface of the drying cylinder 1 in this embodiment, and the distance and included angle between two adjacent support legs are equal.

[0028] It should be noted that, in order to facilitate the discharge of liquid from the drying cylinder 1, the bottom of the drying cylinder 1 in this embodiment is a conical structure, and a liquid outlet pipe is fixedly installed at the bottom of the drying cylinder 1, with a valve fixedly installed inside the liquid outlet pipe.

[0029] It should be noted that the outer diameter of centrifuge cylinder 4 is smaller than the inner diameter of drying cylinder 1.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, refrigerant is injected into the drying cylinder 1 through the liquid inlet pipe 16. Under the action of the guide pipe 17, the refrigerant enters the centrifuge cylinder 4. The motor 10 is started, and the motor 10 drives the rotating rod 11 to rotate, which in turn causes the rotating rod 11 to drive the centrifuge cylinder 4 to rotate on the upper surface of the mounting block 3, causing the ring 13 to slide in the annular groove 12, which in turn drives the centrifuge cylinder 4 to rotate in the drying cylinder 1, so that the centrifuge cylinder 4 generates centrifugal force. The water filter sleeve 5 adsorbs the moisture in the refrigerant. The refrigerant is thrown out of the centrifuge cylinder 4 through the liquid outlet 14 and enters the drying cylinder 1. It flows through the liquid leakage hole 15 on the mounting plate 2 to the first filter sleeve 6 and the second filter sleeve 7. The solid desiccant 8 in the first filter sleeve 6 and the water-absorbing cotton 9 in the second filter sleeve 7 perform secondary adsorption and filtration of the moisture in the refrigerant. The refrigerant filtered by the solid desiccant 8 and the water-absorbing cotton 9 is discharged from the drying cylinder 1 through the liquid outlet pipe.
