Description

Technical Field

[0001] The present invention relates to the technical field of refrigerant recovery, and in particular to a refrigerant recovery device for refrigeration equipment. Background Art

[0002] The emission of Freon gas will damage the atmosphere, cause the greenhouse effect and lead to a series of environmental problems such as global warming. Refrigeration equipment using Freon refrigerant is used in all walks of life. From source production detection to user use, after-sales maintenance and scrapping, there may be leakage of Freon refrigerant in each link, and even human private emission. As the supervision of Freon refrigerant becomes more and more stringent, it is necessary to strictly monitor, recycle and reuse the Freon refrigerant in the above-mentioned process links. In particular, during the testing and maintenance process, it is often necessary to move the refrigerant in the refrigeration equipment, and it is necessary to ensure that the refrigerant will not leak into the atmosphere when the connecting pipe is disconnected.

[0003] The existing patent (Announcement No.: CN219607442U) discloses a fluorine extraction device, which relates to the technical field of fluorine extraction equipment, including a frame, a refrigerant recovery machine and a fluorine extraction pipe fitting. First, the above-mentioned parts are connected in sequence, and the refrigerant recovery machine is generally placed above the conveyor line. When the other end of the fluorine extraction pipe fitting is connected to the refrigerant pipeline of the refrigeration equipment, the refrigerant medium in the refrigeration equipment can be extracted through the recovery pump. After the fluorine enters the shell, the filtering effect of the filter cover can block most of the impurities from entering the accommodation space, and almost no pollution is caused to the shell. By setting the above structure, the impurities remaining in the refrigerant recovery machine are less. On the one hand, the cleaning work of the refrigerant recovery machine is simple. When actually cleaning, only a clean filter cover needs to be replaced. On the other hand, there are fewer impurities mixed in the refrigerant medium, which reduces the difficulty of refrigerant medium recovery and purification.

[0004] However, the above technical solution still has certain defects. In the process of recycling Freon, the recovery equipment is connected to the recovery tank, and the Freon inside the recovery tank will be in a state of high temperature and high pressure.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] The following describes an embodiment of the present invention based on its overall structure.

[0021] A refrigerant recovery device for a refrigeration device, such as Figures 1 to 14As shown, it includes a heat dissipation explosion-proof mechanism 1, which includes an air intake guide plate 101, a heat dissipation bin 102 is fixedly connected to the top of the air intake guide plate 101, two sets of fans 103 are fixedly connected to the bottom of the inner wall of the air intake guide plate 101, a plurality of discharge ports 104 are arranged on the side wall of the air intake guide plate 101, a plurality of placement grooves 105 corresponding to the discharge ports 104 are arranged on the inner wall of the heat dissipation bin 102, a plurality of ventilation buffer grooves 106 located outside the placement grooves 105 are arranged on the inner wall of the heat dissipation bin 102, a rear wind shield plate 107 is fixedly connected to the side wall of the heat dissipation bin 102, a wind duct 108 is connected to the side wall of the rear wind shield plate 107, a top end of the wind duct 108 extends to the top of the evaporation mechanism 2, and one end of the wind duct 108 located above the evaporation device is rotatably connected to a plurality of heat conduction components 110, and the bottom end of each heat conduction component 110 is respectively connected to another heat conduction component Component 110, the bottom end of the heat-conducting component 110 located below is connected with a connecting pipe 109 extending to the outside of the evaporating mechanism 2, the heat-conducting component 110 is rotatably connected to the air duct 108, the heat-conducting component 110 includes a rotating tube 1101, the rotating tube 1101 is rotatably connected to the top of the air duct 108, and the rotating tube 1101 is connected to the air duct 108, the bottom end of the rotating tube 1101 is connected with a group of connecting heads 1102, the bottom end of the connecting head 1102 is fixedly connected with a connecting shaft 1103, the bottom end of the connecting shaft 1103 is fixedly connected with another group of connecting heads 1102, the side walls of the two groups of connecting heads 1102 are connected with multiple groups of copper sheets 1104, the copper sheets 1104 are wavy, the top end of the connecting tube 109 is connected with the connecting head 1102 inside the heat-conducting component 110 below, and the tops of the multiple groups of heat-conducting components 110 located above are provided with pulley groups 111.

[0022] By placing the recovery tank into the placement groove 105 from the discharge port 104, and then using the fan 103 to push the air into the air intake guide plate 101, and then these airflows pass through the ventilation buffer grooves 106 and hit the rear wind shield 107, so that the air enters the inside of the air duct. In the process of the airflow passing through the ventilation buffer grooves 106, the multiple groups of ventilation buffer grooves 106 increase the contact area between the heat dissipation bin 102 and the airflow. These ventilation buffer grooves 106 are located in the cavity inside the heat dissipation bin 102 and are located on the outer walls of the multiple groups of placement grooves 105, so that when a collision occurs, the impact force can be consumed by the deformation of these ventilation buffer grooves 106 to avoid damage and rupture of the recovery tank. The recovery tank transfers heat to the entire heat dissipation bin 102, so that the heat is taken away by the airflow. After the hot air enters the air guide 108, it enters the multiple groups of transfer The hot air passes through the inside of the tube 1101 and then passes through the inside of the copper sheet 1104 through the connecting head 1102. Then the hot air flows from the upper heat-conducting component 110 to the lower heat-conducting component 110, so that the copper sheet 1104 inside the lower heat-conducting component 110 again dissipates the heat of the airflow. Then the hot air is discharged from the connecting tube 109. While the multiple groups of copper tubes are dissipating heat, the rotating tube 1101 drives the connecting head 1102 to rotate, and the connecting head 1102 drives the copper sheet 1104 to rotate. The copper sheet 1104 is wavy, which makes the surface area of ​​the copper sheet 1104 larger, and the copper sheet 1104 rotates continuously, so that the copper sheet 1104 can be more fully in contact with the Freon, so that the copper sheet 1104 heats the Freon, thereby increasing the gasification rate of the Freon and allowing the oil mixed in the Freon to maintain good fluidity.

[0023] Please refer to Figure 2 , Figure 6 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13The evaporation mechanism 2 includes a separation chamber 201, a motor 202 is fixedly connected to the top of the separation chamber 201, a transmission shaft 203 is fixedly connected to the output end of the motor 202, a second bevel gear 205 group is fixedly sleeved on the outer wall of the transmission shaft 203, a first bevel gear 204 is fixedly connected to the top of a group of rotating rollers in the pulley group 111, the first bevel gear 204 and the second bevel gear 205, the top of the separation chamber 201 is connected to a plurality of pre-pressing chambers 207, the inner wall of each group of pre-pressing chambers 207 is respectively slidably connected to a second piston 208, the side wall of the second piston 208 is fixedly connected to a pressure spring 209, the end of the pressure spring 209 is fixedly connected to the inner wall of the pre-pressing chamber 207, the ends of the plurality of pre-pressing chambers 207 are connected to a suction assembly 206, the suction assembly 206 includes a lower chamber body 2061, the top of the lower chamber body 2061 is connected to two groups of sleeves 2062, the inner wall of each group of sleeves 2062 is respectively slidably connected to a group of first pistons 2 063, the top of each group of first pistons 2063 is respectively fixedly connected with a group of pull rods 2064 extending to the outside of the sleeve 2062, the tops of the two groups of pull rods 2064 are fixedly connected with brackets 2065, the bottom ends of the brackets 2065 are fixedly connected with slide grooves 2066, the inner wall of the slide groove 2066 is slidably sleeved with a slide rod 2067, one end of the slide rod 2067 is rotatably connected with a connecting rod 6068, the bottom end of the connecting rod 6068 is rotatably connected with a rotating disk 2069, and the connecting rod 6068 is rotatably connected with a rotating disk 2069. The connection between 068 and the turntable 2069 is close to the edge of the turntable 2069. The center point of the turntable 2069 is fixedly connected to the end of the transmission shaft 203. Two groups of first one-way valves 20610 are hinged at the bottom end of the lower warehouse body 2061. Two air outlets are opened at the bottom end of the lower warehouse body 2061, and the two air outlets correspond to the positions of the first one-way valves 20610. The lower warehouse body 2061 is hinged with a group of second one-way valves 20611 at the connection points with multiple groups of pre-pressurization warehouses 207.

[0024] The separation chamber 201 is connected to the refrigeration equipment through a pipeline, so that the Freon inside the refrigeration equipment enters the separation chamber 201, and then the transmission shaft 203 is driven to rotate by the motor 202, and the transmission shaft 203 drives the second bevel gear 205 to rotate, and the second bevel gear 205 drives the first bevel gear 204 to rotate, and the first bevel gear 204 drives a group of heat-conducting components 110 to rotate, so that this group of heat-conducting components 110 drives other heat-conducting components 110 to rotate through the pulley group 111. After the Freon enters the separation chamber 201 from the inside of the refrigeration equipment, due to the reduction in pressure, these Freon are gasified, so that the oil mixed in the Freon gathers at the bottom of the separation chamber 201 and then flows into the oil collecting mechanism 3, through the transmission shaft 20 3 drives the turntable 2069 to rotate, so that the turntable 2069 continuously pushes and pulls the connecting rod 6068, so that the connecting rod 6068 continuously pushes and pulls the sliding rod 2067, and the sliding through the sliding groove 2066 drives the bracket 2065 to continuously reciprocate up and down, and the bracket 2065 drives the pull rod 2064 to slide reciprocatingly up and down, so that the first piston 2063 slides reciprocatingly downward inside the sleeve 2062. During the upward sliding process of the first piston 2063, the first one-way valve 20610 is tightly adsorbed by the negative pressure inside the sleeve 2062, so that the first one-way valve 20610 is tightly fitted with the bottom end of the lower warehouse body 2061. At this time, the second one-way valve 20611 is adsorbed and opened by the negative pressure inside the sleeve 2062, so that the air inside the pre-pressurization chamber 207 is sucked into the lower warehouse body 2061. During the downward sliding of the first piston 2063, the air inside the sleeve 2062 and the lower chamber 2061 is compressed, so that the first one-way valve 20610 is pushed open by the air pressure, and the second one-way valve 20611 is tightly fitted with the inner wall of the lower chamber 2061 under the action of the air pressure, so that the gas inside the lower chamber 2061 and the sleeve 2062 is discharged. Before performing the above operation, the air outlet is connected to the recovery tank through a pipeline. After the gas inside the pre-pressing chamber 207 is sucked into the lower chamber 2061, a negative pressure is generated inside the pre-pressing chamber 207, so that the second piston 208 is driven by the negative pressure, so that the second piston 208 slides inside the pre-pressing chamber 207 and compresses the pressure spring 209. As the pressure inside the pre-pressing chamber 207 The gas in the upper part is continuously extracted, so that the first piston 2063 slides continuously inside the pre-compression chamber 207. During the sliding process of the second piston 208, negative pressure is generated inside the separation chamber 201 until a gap appears between the second piston 208 and the inner wall of the pre-compression chamber 207. At this time, the Freon entering the separation chamber 201 is sucked into the lower chamber body 2061, and then these Freon enters the recovery tank through the pipeline. After the Freon behind the refrigeration equipment is emptied, the pipeline connected to the refrigeration equipment is disconnected, and the recovery of Freon is completed at this time. In the process of sucking the Freon inside the separation chamber 201 by negative pressure, the negative pressure state inside the separation chamber 201 makes the Freon easier to gasify, and when the negative pressure inside the lower chamber body 2061 is small,The pressure spring 209 rebounds and pushes the second piston 208 to reset, so that the separation chamber 201 is disconnected from the lower chamber body 2061. When the negative pressure inside the lower chamber body 2061 is strong, the second piston 208 compresses the pressure spring 209 again, so that the separation chamber 201 is connected with the lower chamber body 2061. When the second piston 208 is subjected to excessive negative pressure, the second piston 208 slides toward the end of the pre-compression chamber 207 close to the lower chamber body 2061, so that the second piston 208 fits with the inner wall of this end, so that the pre-compression chamber 207 is not connected with the lower chamber body 2061. Therefore, when the pressure is too high or too low, the pre-compression chamber 207 cannot be connected with the lower chamber body 2061, so that the negative pressure inside the separation chamber 201 is always within a certain range, avoiding the evaporation of water and oil mixed in the Freon due to excessive negative pressure, and avoiding the inefficient gasification of Freon due to too low negative pressure.

[0025] Please refer to Figure 1 , Fig.13 and Fig.14 The side wall of the separation chamber 201 is connected to an oil collecting mechanism 3, which includes an upper cover 301. The top of the upper cover 301 is connected to the separation chamber 201. The bottom of the upper cover 301 is threadedly connected to a lower cover 302. The lower cover 302 is internally sleeved with a packing chamber 303. The packing chamber 303 includes a plastic chamber 3031. The plastic chamber 3031 is sleeved inside the lower cover 302. The outer wall of the plastic chamber 3031 is fixedly sleeved with multiple groups of magnetic strips 3032. The magnetic strips 3032 Adsorbed on the inner wall of the lower cover 302, the top of the plastic cabin 3031 is connected to a film feed port 3033, and multiple sets of socket blocks 3034 are fixedly connected at the top edge of the film feed port 3033. The inner walls of the multiple sets of socket blocks 3034 are slidably sleeved with two sets of straps 3035, one end of the two sets of straps 3035 is fixedly connected to the side wall of a set of socket blocks 3034, and the other ends of the two sets of straps 3035 are respectively fixedly connected to a set of magnets, and the magnets are adsorbed on the inner wall of the upper cover 301.

[0026] After the oil flows into the upper cover 301, it falls on the film feed port 3033, and then flows into the plastic chamber 3031. After the Freon recovery is completed, the lower cover 302 is rotated to separate the lower cover 302 from the upper cover 301, and then the lower cover 302 is pulled downward, so that the lower cover 302 drives the plastic chamber to move downward through the magnetic strip 3032, and the plastic chamber 3031 drives the film feed port 3033 to move downward, so that the sleeve block 3034 moves downward, so that one end of the strap 3035 is pulled, and the strap 3035 is pulled downward. A magnet is fixed on the other end of 035, and the magnet is adsorbed on the inner wall of the upper cover 301, so that the multiple sets of socket blocks 3034 are driven, thereby tightening the film feed port 3033. After the film feed port 3033 is tightened, the lower cover 302 is continued to be pulled so that the pulling force on the magnet is greater than the adsorption force, thereby separating the magnet from the upper cover 301. Then, you only need to pull the plastic cabin 3031 out from the inside of the lower cover 302 to conveniently pack the oil and prevent oil leakage, and there is no need to clean the inside of the lower cover 302.

[0027] During use, air passes through the ventilation buffer groove 106, so that the airflow takes away the heat emitted by the recovery tank, and the hot air flows into the connecting pipe 109 through the copper sheet 1104 and is finally discharged from the recovery device. In the process of the air flowing through the copper sheet 1104, the heat in the airflow can be transferred to the refrigerant more quickly through the excellent thermal conductivity of the copper sheet 1104 and the larger surface area brought by the wavy shape of the copper sheet 1104. The continuous rotation of the copper sheet 1104 also allows the copper sheet 1104 to be in more full contact with the refrigerant, so that the internal energy accumulated by the refrigerant in the process of being compressed into the recovery tank is consumed, avoiding the explosion of the recovery tank due to excessive temperature. The ventilation buffer groove 106 is located in the cavity inside the heat dissipation bin 102 and on the outer wall of the multiple groups of placement grooves 105, so that when a collision occurs, the impact force can be consumed through the deformation of the ventilation buffer grooves 106 to avoid damage and rupture of the recovery tank. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
