Description

Technical Field

[0001] The invention relates to the technical field of automobile air conditioners, in particular to a gas-liquid separator for automobile air conditioners with an anti-blocking structure. Background Art

[0002] The gas-liquid separator for automobile air conditioning is an important component in the automobile air conditioning refrigeration system. It is mainly used to separate the gas-liquid mixed refrigerant at the outlet of the evaporator in the refrigeration cycle, ensure that the refrigerant entering the compressor is gaseous, protect the compressor and improve the efficiency of the refrigeration system. The gas-liquid mixed refrigerant coming out of the evaporator is separated into gaseous refrigerant and liquid refrigerant, so that the gaseous refrigerant can smoothly enter the compressor for compression, prevent the liquid refrigerant from entering the compressor to cause liquid hammer and damage the compressor, and temporarily store the separated liquid refrigerant to ensure a stable supply of refrigerant in the refrigeration system to meet the refrigeration needs under different working conditions.

[0003] In the existing device, a filter is set at the inlet of the separator to intercept larger impurity particles and prevent them from entering the separator and causing blockage. However, when the filter is filtered for a long time, the filter mesh will cause blockage, which will slow down the passage of the gas-liquid mixture into the separator. Summary of the invention

[0009] When the mesh holes on the filter plate are clogged, and the impact force of the gas-liquid mixture passing through the filter plate is less than the tensile force of the first spring, the bracket is pulled by the reset of the first spring, so that the bracket drives the round rod to move toward the mesh holes of the filter plate, so that the round rod pushes out the impurities clogged in the mesh holes of the filter plate, thereby clearing the mesh holes of the filter plate;

[0010] Preferably, the cleaning mechanism comprises a spiral blade, a rotating block is fixedly connected to the side of the spiral blade, a side of the rotating block away from the spiral blade is rotatably connected to a side of the filter plate away from the bracket, a cleaning rod is fixedly connected to the side of the rotating block, the number of the cleaning rods is three, the three cleaning rods are evenly arranged with the rotating block as the center, the cleaning rods are evenly provided with clearance grooves, and the inner side of the clearance groove is fixedly connected to a contact assembly;

[0011] When the gas-liquid mixed refrigerant passes through the filter plate, the gas-liquid mixture impacts the spiral blade, so that the spiral blade drives the cleaning rod to clean the side of the filter plate through the rotating block, and the cleaning mechanism drives the contact assembly to rotate on the side of the filter plate;

[0012] Preferably, the contact assembly includes a contact rod, one end of the contact rod is fixedly connected to the inner side of the give way groove, a sliding groove is opened on the side of the contact rod, a slider is slidably connected to the inner side of the sliding groove, the side of the slider is fixedly connected to the sliding rod, the side of the sliding rod is slidably connected to the inner side of the contact rod, a second spring is sleeved on the sliding rod, one end of the second spring is fixedly connected to the side of the contact plate away from the contact brush, the other end of the second spring is fixedly connected to the end of the contact rod away from the give way groove, the end of the sliding rod away from the slider is fixedly connected to the contact plate, both sides of the contact plate are rotatably connected with connecting rods, the number of the contact plates is five, the number of the connecting rods is four, the connecting rod is arranged between the two contact plates, and the side of the contact plate away from the contact rod is fixedly connected to the contact brush;

[0013] When the cleaning rod is driven by the rotating block and the spiral blade to rotate on the filter plate, the contact plate moves in the sliding groove in the contact rod through the slider and the slide rod, driving the contact plate and the contact brush to clean the side of the filter plate. At the same time, multiple contact plates and contact brushes are arranged on the cleaning rod and connected by a connecting rod, so that the contact plate drives the contact brush to clean the side of the filter plate.

[0014] Preferably, the discharging component comprises a discharging pipe, the side of the discharging pipe is fixedly connected to the inner side of the main body away from the feeding pipe, the inner side of the discharging pipe is fixedly connected to a mesh plate, and the side of the mesh plate is rotatably connected to a rotating mechanism;

[0015] When the refrigeration system is running, there is a pressure difference between the refrigeration pipeline inside and outside the gas-liquid separator. Under the suction action of the compressor, the pressure inside the refrigeration pipeline outside the gas-liquid separator is relatively low, while the gaseous refrigerant after separation in the gas-liquid separator is at a relatively high pressure state. This pressure difference will push the pure gaseous refrigerant to flow out from the gas outlet of the gas-liquid separator, enter the refrigeration pipeline with lower pressure, and flow to the compressor and other subsequent components, completing the gaseous refrigerant transportation process in the refrigeration cycle. When the pure gaseous refrigerant flows out through the discharge pipe and passes through the mesh plate, the mesh plate intercepts the tiny droplets and impurities in the gaseous refrigerant. The mesh plate can change the direction of the airflow, so that the droplets in the gaseous refrigerant collide with the mesh plate and fall under the action of inertia, thereby ensuring the purity of the outflowing gaseous refrigerant.

[0016] Preferably, the rotating mechanism comprises a rotating rod, the side of the rotating rod is rotatably connected to the inner side of the mesh plate, the end of the rotating rod away from the mesh plate is fixedly connected to the guide plate, the side of the rotating rod is fixedly connected to the rotating frame, and the end of the rotating frame away from the rotating rod is fixedly connected to the collecting assembly;

[0017] When the gaseous refrigerant passes through the discharge pipe, it impacts the guide plate, so that the guide plate drives the collecting assembly to rotate in the discharge pipe through the rotating rod and the rotating frame, so that the collecting assembly collects the impurities blocked by the mesh plate;

[0018] Preferably, the collecting assembly includes a collecting shell, a side surface of the collecting shell is fixedly connected to an end of the rotating frame away from the rotating rod, through holes are evenly opened on the side surface of the collecting shell, a connecting rod is slidably connected to the inner side of the collecting shell, an end of the connecting rod away from the collecting shell is fixedly connected to a baffle, a side of the baffle close to the connecting rod is abutted against the side surface of the collecting shell, an arc plate is fixedly connected to the connecting rod, a third spring is sleeved on the connecting rod, one end of the third spring is fixedly connected to the arc plate, the other end of the third spring is fixedly connected to the inner side of the collecting shell, and arc blocks are fixedly connected to both sides of the inner cavity of the collecting shell;

[0019] When the collecting shell is driven to rotate by the rotating rod and the rotating frame, the collecting shell continuously collides with the gaseous refrigerant entering the discharge pipe;

[0020] Through the action of centrifugal force, the baffle pulls the connecting rod and the third spring to separate from the collecting shell, and at the same time, the connecting rod drives the arc plate and the arc block to counteract each other, so that the mesh plate intercepts impurities in the gaseous refrigerant. When the collecting shell rotates with the rotating frame, the impurities enter the collecting shell through the gap formed by the baffle separating from the collecting shell, thereby collecting and processing the impurities intercepted by the mesh plate;

[0021] At the same time, when the baffle is separated from the collecting shell, the arc plate is driven to move by the connecting rod, so that the two sides of the arc plate are against the arc block, thereby preventing impurities in the collecting shell from flowing out of the collecting shell. At the same time, through holes are evenly opened on the collecting shell, so that the gaseous refrigerant entering the collecting shell can pass through the through holes and separate from the collecting shell.

[0022] The present invention provides a gas-liquid separator for automobile air conditioner with an anti-blocking structure. It has the following beneficial effects:

[0023] 1. The gas-liquid separator for automobile air conditioner with anti-blocking structure is provided with a feeding component. When the mesh holes on the filter plate are blocked and the impact force of the gas-liquid mixture passing through the filter plate is less than the tensile force of the first spring, the bracket is pulled by the reset of the first spring, so that the bracket drives the round rod to move toward the mesh holes of the filter plate, so that the round rod pushes out the impurities blocked in the mesh holes of the filter plate, thereby clearing the mesh holes of the filter plate.

[0024] 2. The gas-liquid separator for automobile air conditioning with an anti-blocking structure is provided with a contact plate and a contact brush. This modular structural design makes each contact plate and contact brush relatively independent but interconnected, which is convenient for disassembly and replacement when necessary. If a contact brush is damaged or severely worn, it can be replaced separately without affecting the normal operation of other contact brushes, thereby reducing maintenance costs and difficulty.

[0025] 3. The gas-liquid separator for automobile air conditioning with an anti-blocking structure is provided with a contact assembly, and a connecting rod connects multiple contact plates to form a linkage structure. When one of the contact plates encounters greater resistance during the cleaning process, the force can be transmitted to other contact plates through the connecting rod, so that the contact plates can cooperate with each other to maintain the overall stability, avoid shaking or deviation of a single contact plate due to uneven force, and ensure the stable progress of the cleaning work.

[0026] 4. The gas-liquid separator for automobile air conditioning with an anti-blocking structure is provided with a collecting component, and a through hole is opened on the collecting shell so that the gaseous refrigerant entering the collecting shell can escape through the through hole, thereby achieving effective separation of the gaseous refrigerant and impurities. This helps to keep the collecting shell mainly composed of impurities and avoids the accumulation of gaseous refrigerant in the collecting shell and affecting the impurity collection effect.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 3 The present invention provides a technical solution: a gas-liquid separator for automobile air conditioner with an anti-blocking structure, comprising:

[0039] A main body 1, a lifting ring 5 is fixedly connected to the top of the main body 1, a liquid collecting filter 4 is fixedly connected to the bottom of the main body 1, an automatic drain valve 10 is fixedly connected to the bottom of the liquid collecting filter 4, a reversing plate 6 is fixedly connected to the inner side of the main body 1, a liquid guide tube 7 is fixedly connected to the inner side of the reversing plate 6, a swirl reversing ring 8 is fixedly connected to the side of the liquid guide tube 7, and a liquid separation plate 9 is fixedly connected to the inner cavity of the main body 1, and the liquid separation plate 9 is arranged below the liquid guide tube 7;

[0040] A feeding component 2, the side surface of the feeding component 2 is fixedly connected to the inner side of the main body 1;

[0041] A discharging component 3, the side surface of which is fixedly connected to a side of the main body 1 away from the feeding component 2;

[0042] See also Figure 1-Figure 3The feeding component 2 includes a feeding pipe 21, the side of the feeding pipe 21 is fixedly connected to the inner side of the main body 1, the inner side of the feeding pipe 21 is fixedly connected with a filter plate 22, the side of the filter plate 22 is slidably connected with a connecting shaft 23, a first spring 24 is sleeved on the connecting shaft 23, one end of the first spring 24 is fixedly connected to a bracket 25, the other end of the first spring 24 is fixedly connected to the filter plate 22, the end of the connecting shaft 23 away from the filter plate 22 is fixedly connected to the bracket 25, the side of the bracket 25 close to the filter plate 22 is evenly provided with round rods 26, the round rods 26 are concentrically arranged with the mesh of the filter plate 22, the round rods 26 are fixedly connected to the end of the bracket 25 close to the filter plate 22, and the side of the filter plate 22 away from the connecting shaft 23 is rotatably connected with a cleaning mechanism 27;

[0043] When the gas-liquid mixture passes through the connecting pipe and enters the feed pipe 21, the impact force of the gas-liquid mixture causes the cleaning mechanism 27 to rotate on the filter plate 22. At the same time, the gas-liquid mixture continuously impacts the filter plate 22, and the filter plate 22 intercepts larger impurity particles in the gas-liquid mixture. By setting the tensile force of the first spring 24 to be smaller than the impact force of the gas-liquid mixture, when the gas-liquid mixture continuously passes through the filter plate 22, the bracket 25 is subjected to the impact force, so that the bracket 25 moves to the side away from the filter plate 22 through the connecting shaft 23;

[0044] When the mesh holes on the filter plate 22 are clogged, and the impact force of the gas-liquid mixture passing through the filter plate 22 is less than the tensile force of the first spring 24, the bracket 25 is pulled by the reset of the first spring 24, so that the bracket 25 drives the round rod 26 to move toward the mesh holes of the filter plate 22, so that the round rod 26 pushes out the impurities clogged in the mesh holes of the filter plate 22, thereby clearing the mesh holes of the filter plate 22. At the same time, the length of the round rod 26 passing through the mesh holes of the filter plate 22 is less than the thickness of the filter plate 22, so as to avoid the phenomenon that the round rod 26 interferes with the contact component 275 when clearing the blockage.

[0045] See also Figure 4-Figure 5 The cleaning mechanism 27 includes a spiral blade 271, a rotating block 273 is fixedly connected to the side of the spiral blade 271, a side of the rotating block 273 away from the spiral blade 271 is rotatably connected to a side of the filter plate 22 away from the bracket 25, a cleaning rod 272 is fixedly connected to the side of the rotating block 273, and the number of the cleaning rods 272 is three, and the three cleaning rods 272 are evenly arranged with the rotating block 273 as the center, and the cleaning rods 272 are evenly provided with clearance grooves 274, and the inner side of the clearance grooves 274 is fixedly connected to the contact assembly 275;

[0046] When the gas-liquid mixed refrigerant passes through the filter plate 22, the gas-liquid mixed refrigerant impacts the spiral blade 271, so that the spiral blade 271 drives the cleaning rod 272 to clean the side of the filter plate 22 through the rotating block 273, and the cleaning mechanism 27 drives the contact assembly 275 to rotate on the side of the filter plate 22;

[0047] See also Figure 1-Figure 6 The contact assembly 275 includes a contact rod 2751, one end of which is fixedly connected to the inner side of the give way groove 274, a sliding groove 2752 is provided on the side of the contact rod 2751, a slider 2754 is slidably connected to the inner side of the sliding groove 2752, a sliding rod 2753 is fixedly connected to the side of the slider 2754, a side of the sliding rod 2753 is slidably connected to the inner side of the contact rod 2751, a second spring 2755 is sleeved on the sliding rod 2753, one end of the second spring 2755 is away from the contact brush 275 with the contact plate 2756 8, the other end of the second spring 2755 is fixedly connected to the end of the contact rod 2751 away from the give way groove 274, the end of the slide bar 2753 away from the slider 2754 is fixedly connected to the contact plate 2756, both sides of the contact plate 2756 are rotatably connected to the connecting rod 2757, the number of the contact plates 2756 is five, the number of the connecting rods 2757 is four, the connecting rod 2757 is arranged between the two contact plates 2756, and the side of the contact plate 2756 away from the contact rod 2751 is fixedly connected to the contact brush 2758;

[0048] When the cleaning rod 272 is driven by the rotating block 273 and the spiral blade 271 to rotate on the filter plate 22, the contact plate 2756 is moved in the sliding groove 2752 in the contact rod 2751 through the slider 2754 and the slide rod 2753, driving the contact plate 2756 and the contact brush 2758 to clean the side of the filter plate 22. At the same time, a plurality of contact plates 2756 and contact brushes 2758 are provided on the cleaning rod 272 and connected by the connecting rod 2757, so that the contact plate 2756 drives the contact brush 2758 to clean the side of the filter plate 22 and clean the impurities pushed out of the mesh of the filter plate 22 by the round rod 26.

[0049] During the cleaning process, the surface conditions of the filter plate 22 may be different, such as local protrusions or depressions. The structure in which multiple contact plates 2756 are connected by connecting rods 2757 can be adaptively adjusted according to the actual conditions of the surface of the filter plate 22. Each contact plate 2756 can move relatively independently within a certain range, ensuring that the contact brush 2758 always maintains good contact with the side of the filter plate 22, thereby improving the cleaning effect and stability.

[0050] During the cleaning process, the contact brush 2758 can always maintain appropriate pressure on the side of the filter plate 22 through the action of the second spring 2755. When encountering more stubborn impurities, the second spring 2755 can provide a certain buffer and elastic force, so that the contact brush 2758 can more effectively remove the impurities without causing excessive wear to the filter plate 22, thereby ensuring continuous and efficient cleaning work;

[0051] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0052] The discharge component 3 includes a discharge pipe 31, the side of which is fixedly connected to the inner side of the main body 1 away from the feed pipe 21, the inner side of the discharge pipe 31 is fixedly connected to a mesh plate 32, and the side of the mesh plate 32 is rotatably connected to a rotating mechanism 33;

[0053] When the refrigeration system is running, there is a pressure difference between the refrigeration pipeline inside and outside the gas-liquid separator. Under the suction action of the compressor, the pressure inside the refrigeration pipeline outside the gas-liquid separator is relatively low, while the separated gaseous refrigerant in the gas-liquid separator is at a relatively high pressure state. This pressure difference will push the pure gaseous refrigerant to flow out from the gas outlet of the gas-liquid separator, enter the refrigeration pipeline with lower pressure, and flow to the compressor and other subsequent components, completing the gaseous refrigerant transportation process in the refrigeration cycle. When the pure gaseous refrigerant flows out through the discharge pipe 31 and passes through the mesh plate 32, the mesh plate 32 intercepts tiny droplets and impurities in the gaseous refrigerant. The mesh plate 32 can change the direction of the airflow, so that the droplets in the gaseous refrigerant collide with the mesh plate 32 under the action of inertia and fall, thereby ensuring the purity of the outflowing gaseous refrigerant.

[0054] See also Figure 1-Figure 8 The rotating mechanism 33 includes a rotating rod 331, the side of the rotating rod 331 is rotatably connected to the inner side of the mesh plate 32, the end of the rotating rod 331 away from the mesh plate 32 is fixedly connected to the guide plate 332, the side of the rotating rod 331 is fixedly connected to the rotating frame 333, and the end of the rotating frame 333 away from the rotating rod 331 is fixedly connected to the collecting assembly 334;

[0055] When the gaseous refrigerant passes through the discharge pipe 31, it impacts the guide plate 332, so that the guide plate 332 drives the collection component 334 to rotate in the discharge pipe 31 through the rotating rod 331 and the rotating frame 333, so that the collection component 334 collects the impurities blocked by the mesh plate 32;

[0056] See also Figure 1-Figure 9The collecting assembly 334 includes a collecting shell 3341, a side of the collecting shell 3341 is fixedly connected to an end of the rotating frame 333 away from the rotating rod 331, through holes 3342 are evenly opened on the side of the collecting shell 3341, a connecting rod 3344 is slidably connected to the inner side of the collecting shell 3341, an end of the connecting rod 3344 away from the collecting shell 3341 is fixedly connected to a baffle 3343, a side of the baffle 3343 close to the connecting rod 3344 is against the side of the collecting shell 3341, an arc plate 3346 is fixedly connected to the connecting rod 3344, a third spring 3345 is sleeved on the connecting rod 3344, one end of the third spring 3345 is fixedly connected to the arc plate 3346, the other end of the third spring 3345 is fixedly connected to the inner side of the collecting shell 3341, and arc blocks 3347 are fixedly connected to both sides of the inner cavity of the collecting shell 3341;

[0057] When the collecting shell 3341 is driven to rotate by the rotating rod 331 and the rotating frame 333, the collecting shell 3341 continuously collides with the gaseous refrigerant entering the discharge pipe 31;

[0058] Through the action of centrifugal force, the baffle 3343 pulls the connecting rod 3344 and the third spring 3345 to separate from the collecting shell 3341, and at the same time, the connecting rod 3344 drives the arc plate 3346 to counteract the arc block 3347, so that the mesh plate 32 intercepts impurities in the gaseous refrigerant. When the collecting shell 3341 rotates with the rotating frame 333, the impurities enter the collecting shell 3341 through the gap formed by the baffle 3343 separating from the collecting shell 3341, so that the impurities intercepted by the mesh plate 32 are collected and processed;

[0059] At the same time, when the baffle 3343 is separated from the collecting shell 3341, the arc plate 3346 is driven to move by the connecting rod 3344, so that the two sides of the arc plate 3346 are against the arc block 3347, thereby preventing the impurities in the collecting shell 3341 from flowing out of the collecting shell 3341. At the same time, through holes 3342 are evenly opened on the collecting shell 3341, so that the gaseous refrigerant entering the collecting shell 3341 can pass through the through holes 3342 and separate from the collecting shell 3341.

[0060] When the baffle 3343 is separated from the collecting housing 3341 and impurities enter, the two sides of the arc plate 3346 abut against the arc block 3347 to form an effective seal, preventing the collected impurities from flowing out of the collecting housing 3341, ensuring that the impurities are properly collected and prevented from entering the refrigeration system again to cause harm;

[0061] The gaseous refrigerant impacts the guide plate 332, driving the collecting assembly 334 to rotate, which can actively collect the impurities that fall from the mesh plate 32, prevent the impurities from accumulating in the discharge pipe 31, ensure that the discharge pipe 31 is unobstructed, and maintain the normal operation of the refrigeration system.

[0062] Specific workflow:

[0063] The gas-liquid mixed refrigerant from the automobile air conditioner evaporator passes through the connecting pipe at a certain speed and pressure, and enters the main body 1 from the tangential feed component 2 on the side of the separator. The design of the inlet of the tangential reversing plate 6 allows the gas-liquid mixture to rotate along the inner wall of the separator after entering;

[0064] After the gas-liquid mixture enters the main body 1, due to the effect of the tangential inlet, it begins to perform high-speed spiral rotation in the main body 1 to form a vortex. Under the action of centrifugal force, the liquid refrigerant with a larger density is thrown to the cylinder wall of the main body 1, while the gaseous refrigerant with a smaller density is in the center area of ​​the vortex. Under the action of centrifugal force, the liquid refrigerant obtains an outward acceleration, thereby separating from the gaseous refrigerant.

[0065] The liquid refrigerant thrown onto the wall of the main body 1 will form a liquid film along the wall and flow downward. During the downward flow, the liquid refrigerant in the liquid film will continue to converge and eventually flow to the bottom of the main body 1, forming a storage area for the liquid refrigerant at the bottom.

[0066] The liquid collecting filter 4 can collect the liquid refrigerant in the main body 1, so that the liquid refrigerant forms a certain liquid level at the bottom of the main body 1, which is convenient for subsequent treatment and recycling;

[0067] The gaseous refrigerant in the central area of ​​the cyclone continues to maintain the spiral motion state and flows upward in the main body 1. Since the gas is in the central area, the centrifugal force it is subjected to is small, and it can move relatively smoothly to the upper part of the main body 1;

[0068] After centrifugal separation and secondary separation of tiny droplets, relatively pure gaseous refrigerant flows out from the discharge component 3 of the main body 1, is transported to the air intake port of the compressor through a pipeline, enters the compressor for compression, and continues to complete the automobile air conditioning refrigeration cycle.

[0069] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
