Description

Technical Field

[0001] This utility model belongs to the field of refrigerant recovery technology, specifically relating to a mobile refrigerant recovery, condensation and purification device. Background Technology

[0002] In the field of refrigeration equipment maintenance and refrigerant recovery, traditional refrigerant recovery devices have the following technical problems:

[0003] 1. Insufficient portability and high disassembly costs:

[0004] Existing recycling devices are mostly fixed or have poor mobility. When recycling refrigerant from high-altitude equipment such as air conditioning units on the exterior walls of high-rise buildings, the units need to be dismantled and transported to the recycling point, which makes the dismantling process complicated, costly, and poses safety hazards for high-altitude operations.

[0005] 2. The filtration system is inefficient and requires operation to be interrupted:

[0006] Traditional recycling devices typically use a single-structure filter unit. Once the filter layer becomes saturated with impurities, the machine must be shut down to replace the filter components. This makes it impossible to meet the needs of long-term continuous recycling on-site, resulting in low operational efficiency. It is especially unsuitable for large-scale or emergency recycling scenarios.

[0007] 3. Risk of equipment failure due to insufficient refrigerant purity:

[0008] Existing filtration technologies have limited ability to remove impurities (such as moisture, oil, and metal particles) from refrigerants. If the refrigerant is not filtered sufficiently, it can easily cause wear and blockage of core components such as compressors, increase the probability of equipment failure, and reduce the recovery efficiency and refrigerant reuse rate.

[0009] 4. Poor structural stability and ease of maintenance:

[0010] Traditional recycling equipment typically has a fixed connection between the main body and the base, requiring complete disassembly for maintenance or replacement of parts, which is time-consuming and labor-intensive. Furthermore, the filter components are usually installed in a fixed manner, making filter replacement cumbersome and further impacting operational efficiency. Utility Model Content

[0011] The purpose of this invention is to provide a mobile refrigerant recovery, condensation and purification device to solve the technical defects of existing refrigerant recovery devices, such as low filtration efficiency, high risk of equipment failure, and poor structural stability and ease of maintenance.

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] A mobile refrigerant recovery, condensation, and purification device includes a placement plate. A main body of the recovery equipment is placed on the top side of the placement plate. The main body of the recovery equipment is fixedly connected to the placement plate via detachable parts. Self-locking pulley groups are fixedly connected to the bottom of the four corners of the placement plate. A groove is formed on the top side of the placement plate. A positioning rod is fixedly connected inside the groove. A rotating ring is rotatably sleeved on the surface of the positioning rod. A pull rod is fixedly connected to the top of the rotating ring. A filter element for filtering the recovered refrigerant is provided on one side of the main body of the recovery equipment.

[0014] As a further embodiment of this utility model, the filter element includes a housing fixedly installed on the top of one side of the main body of the recycling equipment. A receiving groove is provided on one side of the housing. An installation column is rotatably connected to the inner cavity of the receiving groove. Three sets of installation holes are provided on the top of the installation column. The three sets of installation holes are arranged in a circular array. A flow hole communicating with one of the sets of installation holes is provided on the top and bottom of the housing. A connecting pipe is connected to the opening of the upper flow hole. The other end of the connecting pipe is connected to the input end of the main body of the recycling equipment. A connecting pipe for connecting a refrigeration device is connected to the opening of the lower flow hole. A filter cylinder is inserted into the inner cavity of the three sets of installation holes. The inside of the filter cylinder is filled with a filter layer.

[0015] As a further embodiment of this utility model, the top openings of the three sets of filter cylinders are respectively threaded with threaded posts, and the top of the threaded posts is provided with several sets of filter holes. When the threaded posts are threaded to the openings of the filter cylinders, the top of the threaded posts is flush with the openings of the filter cylinders.

[0016] As a further embodiment of this utility model, a circular groove is provided on the top inner wall of the shell, and a spring is fixedly connected to the top inner wall of the circular groove. A positioning post is provided at the bottom of the spring and in the inner cavity of the circular groove. The top of the positioning post is fixedly connected to the bottom of the spring. A positioning groove adapted to the end of the positioning post is provided on the top of the mounting post and on the inner side of each set of mounting holes. The three sets of positioning grooves are arranged in a circular array. When the mounting post is rotated to switch the filter cylinder, the positioning post and the positioning groove cooperate to ensure that the flow hole is aligned.

[0017] As a further embodiment of this utility model, each set of mounting holes has two sets of anti-detachment grooves at its opening, and each set of anti-detachment grooves has an anti-detachment plate snapped into its inner cavity. The two sets of anti-detachment plates on the same side are respectively fixedly connected to the ends of the corresponding filter cylinder.

[0018] As a preferred embodiment of this utility model, the detachable component includes fixing plates that are fixedly installed at the four corners of the main body of the recycling equipment. Each set of fixing plates has a fixing bolt inserted into its surface. Each set of fixing bolts passes through the corresponding side fixing plate and is threaded to the top of the placement plate.

[0019] Compared with existing technologies, the mobile refrigerant recovery, condensation, and purification device of this invention has the following advantages:

[0020] 1. Improved mobility and adaptability to different scenarios:

[0021] The placement plate, combined with the design of the self-locking pulley block and tie rod, allows the device to be flexibly moved to the location of high-altitude equipment (such as the outdoor unit of an air conditioner on the exterior wall of a high-rise building). Refrigerant can be recovered on-site without dismantling the equipment, significantly reducing dismantling costs and the risks of high-altitude operations, and is suitable for various complex installation environments.

[0022] 2. Optimization of filtration efficiency and continuous operation capability:

[0023] The switchable filter assembly, consisting of a housing, mounting posts, and multiple filter cartridges, allows for the replacement of filter units without interrupting the recycling process, meeting the needs of long-term continuous operation. The filter layer's efficient adsorption of impurities in the refrigerant (such as moisture, oil, and particulate contaminants) improves the purity of the recovered refrigerant and reduces equipment malfunctions caused by impurities.

[0024] 3. Enhanced structural reliability and ease of maintenance:

[0025] The elastic locking structure of the positioning column and positioning groove ensures precise docking when switching filter units. The anti-detachment groove and anti-detachment plate design prevents the filter cylinder from loosening and ensures system stability. The detachable parts (fixing plate and fixing bolt) enable quick installation and disassembly of the main body of the recycling equipment. The filter cylinder with threaded column connection facilitates filter layer replacement and reduces maintenance difficulty.

[0026] 4. Improved overall operational efficiency and economy:

[0027] Mobile on-site recycling eliminates the need for equipment transportation, switchable filter components reduce downtime, and high-efficiency filtration lowers equipment maintenance costs, thus improving the overall efficiency and economy of refrigerant recovery. It is suitable for various applications such as industrial sites and maintenance services. Attached Figure Description

[0040] See appendix Figure 1-4As shown in the figure, a mobile refrigerant recovery, condensation and purification device according to an embodiment of the present invention includes a placement plate 100. A recovery device body 104 is placed on the top of one side of the placement plate 100. The recovery device body 104 is fixedly connected to the placement plate 100 by a detachable component. Self-locking pulley groups 108 are fixedly connected to the bottom of the four corners of the placement plate 100. A groove 109 is opened on the top of one side of the placement plate 100. A positioning rod 107 is fixedly connected inside the groove 109. A rotating ring 106 is rotatably sleeved on the surface of the positioning rod 107. A pull rod 105 is fixedly connected to the top of the rotating ring 106. A filter element for filtering the recovered refrigerant is provided on one side of the recovery device body 104. The self-locking pulley groups 108 at the four corners of the placement plate 100, together with the pull rod 105, enable the device to move flexibly and easily reach the location of the outdoor unit of the air conditioner on the exterior wall of a high-rise building. There is no need to dismantle the outdoor unit and transport it to the recovery point, thus reducing the dismantling cost.

[0041] The main body of the recycling equipment 104 is a well-known technical means in the art. For its specific working principle and structure, please refer to the recycling device body in a mixed refrigerant recycling device with publication number CN215571413U. Other details will not be elaborated here.

[0042] The filter element includes a housing 200 fixedly installed on the top side of one side of the main body 104 of the recycling equipment. A receiving groove 203 is provided on one side of the housing 200. A mounting post 208 is rotatably connected to the inner cavity of the receiving groove 203. Three sets of mounting holes 306 are provided on the top of the mounting post 208, arranged in a circular array. Flow holes 202 are provided at the top and bottom of the housing 200, communicating with one set of mounting holes 306. A connecting pipe 201 is connected to the opening of the upper flow hole 202, and the other end of the connecting pipe 201 is connected to the input end of the main body 104 of the recycling equipment. A connecting pipe for connecting to a refrigeration device is connected to the opening of the lower flow hole 202. The filter cylinder 300 is inserted into the inner cavity of the pipe 103 and the three sets of mounting holes 306. The filter cylinder 300 is filled with a filter layer 302. Through the setting of the filter element, the filter assembly composed of the housing 200, the mounting column 208 and the multiple sets of filter cylinders 300 can switch filter units without interrupting the recovery operation. It is suitable for the need for long-term continuous recovery of refrigerant on site. The refrigerant enters the main body 104 of the recovery equipment through the connecting pipe 103, the mounting hole 306, the filter cylinder 300 and the connecting pipe 201 in sequence through a specific flow path. It effectively removes impurities, improves the recovery efficiency and refrigerant purity, reduces the failure of the recovery equipment caused by impurities, and reduces the difficulty of on-site recovery work.

[0043] The filter layer 302 is formed by one or more of the following: silica gel desiccant, molecular sieve, activated carbon, activated alumina, etc.

[0044] The top openings of the three filter cylinders 300 are respectively threaded with threaded posts 303. The top of the threaded posts 303 has several sets of filter holes 304. When the threaded posts 303 are threaded to the opening of the filter cylinder 300, the top of the threaded posts 303 is flush with the opening of the filter cylinder 300. The threaded posts 303 not only prevent the filter layer 302 from coming out of the filter cylinder 300, but also the flush connection design between the threaded posts 303 and the filter cylinder 300 ensures that the refrigerant enters the filter layer 302 evenly through the filter holes 304, and avoids the accumulation of impurities at the interface. At the same time, the threaded connection method facilitates the replacement of the filter layer 302.

[0045] A circular groove 204 is formed on the top inner wall of the housing 200. A spring 205 is fixedly connected to the top inner wall of the circular groove 204. A positioning post 206 is set at the bottom of the spring 205 and inside the circular groove 204. The top of the positioning post 206 is fixedly connected to the bottom of the spring 205. A positioning groove 207 that matches the end of the positioning post 206 is formed on the top of the mounting post 208 and inside each set of mounting holes 306. The three sets of positioning grooves 207 are arranged in a circular array. When the mounting post 208 is rotated to switch the filter cylinder 300, the positioning post 206 and the positioning groove 207 cooperate to ensure that the flow hole 202 is aligned. The elastic cooperation between the spring 205 and the positioning post 206 allows the mounting post 208 to be automatically positioned and locked in the accurate position when it rotates, ensuring that the flow hole 202 and the mounting hole 306 are precisely aligned, improving the reliability and ease of operation of the filter switching.

[0046] Each set of mounting holes 306 has two sets of anti-detachment grooves 305 at its opening. Each set of anti-detachment grooves 305 has an anti-detachment plate 301 snapped into its inner cavity. The two sets of anti-detachment plates 301 on the same side are fixedly connected to the ends of the corresponding filter cylinder 300. The snapping structure between the anti-detachment plate 301 and the anti-detachment groove 305 effectively prevents the filter cylinder 300 from loosening and falling off when vibrating or changing pressure, ensuring the stability and safety of the filtration process.

[0047] The detachable components include fixing plates 101 that are fixedly installed at the four corners of the main body 104 of the recycling equipment. Each fixing plate 101 has a fixing bolt 102 inserted into its surface. Each fixing bolt 102 passes through the corresponding fixing plate 101 and is threaded to the top of the placement plate 100. The detachable connection between the fixing plates 101 and the fixing bolts 102 provides a secure fixation and convenient disassembly of the main body 104 of the recycling equipment, facilitating the installation, maintenance and replacement of components of the equipment.

[0048] In use, the main body 104 of the recycling equipment is placed on top of the placement plate 100. At the same time, the fixing bolt 102 passes through the fixing plate 101 and is threaded to the top of the placement plate 100 to fix the main body 104 of the recycling equipment. By pulling the lever 105, the self-locking pulley group 108 at the four corners of the placement plate 100 can realize the convenient movement of the device. After reaching the designated position, it is fixed by the self-locking function.

[0049] When it is necessary to recover the refrigerant from the refrigeration equipment, the connecting pipe 103 is connected to the refrigeration equipment. The refrigerant enters the housing 200 through the connecting pipe 103, and enters the mounting hole 306 on the mounting column 208 that is connected to the flow hole 202 through the lower flow hole 202. Then it is filtered by the filter layer 302 of the filter cylinder 300 inside the corresponding mounting hole 306 to remove impurities from the refrigerant. The filtered refrigerant enters the main body 104 of the recovery equipment through the mounting hole 306 on the mounting column 208 that is connected to the upper flow hole 202, the upper flow hole 202, and the connecting pipe 201.

[0050] When the filtration efficiency of the filter layer 302 decreases after prolonged use and needs to be replaced, the mounting column 208 is rotated. At this time, the positioning column 206 disengages from the current positioning groove 207 under the action of the spring 205 and retracts into the circular groove 204. As the mounting column 208 rotates, when the new positioning groove 207 is aligned with the positioning column 206, the positioning column 206 engages with the new positioning groove 207, ensuring that the flow hole 202 is aligned, thereby switching the filter cylinder 300 and ensuring that the filtration process continues.

[0051] Remove the filter cylinder 300 from the mounting hole 306 and remove the threaded post 303 to expose the opening of the filter cylinder 300. Replace the filter layer 302 and screw the threaded post 303 back into the opening of the filter cylinder 300.

[0052] In this embodiment of the utility model, a mobile refrigerant recovery and condensation purification device has self-locking pulley groups 108 at the four corners of the placement plate 100, which, together with the pull rod 105, enable the device to move flexibly and easily reach the location of the air conditioner outdoor unit on the exterior wall of a high-rise building. This eliminates the need to dismantle the outdoor unit and transport it to a recycling point, thus reducing dismantling costs.

[0053] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
