Description

Technical Field

[0001] This utility model belongs to the field of oil-liquid separation technology, specifically relating to a horizontal oil separation container. Background Technology

[0002] In the field of air conditioning system operation (such as large commercial central air conditioning refrigeration, multi-split unit winter heating, and heat pump air conditioning cross-seasonal heat exchange) and system maintenance, oil separation is a core technological step to ensure normal compressor lubrication, prevent heat exchanger efficiency degradation, and extend the service life of the entire air conditioning unit. In air conditioning systems, the high-temperature and high-pressure refrigerant discharged from the compressor carries a large amount of refrigeration oil. If the oil cannot be effectively separated, some of the refrigeration oil will enter heat exchange components such as the evaporator and condenser with the refrigerant, forming an oil film on the pipe walls that hinders heat exchange, leading to a decrease in air conditioning cooling / heating capacity and an increase in energy consumption. At the same time, insufficient oil in the compressor will cause poor lubrication, resulting in component wear or even compressor burnout.

[0003] Horizontal oil separators have become commonly used equipment in air conditioning oil-liquid separation operations due to their advantages of small footprint, large separation capacity, and adaptability to air conditioning system piping layouts (especially suitable for compact installation scenarios in computer rooms). However, some existing horizontal oil separators still have the problem of high maintenance difficulty of filter components in actual applications of air conditioning systems. The long-term circulation of refrigerant oil in air conditioning systems can easily mix with metal shavings generated by compressor wear and oxidation impurities remaining from system piping welding. The filter components of existing equipment are mostly fixed by welding or multiple bolts. When the filter media (such as filter screens and adsorption layers) are blocked by impurities or saturated with adsorption, a large number of connecting structures need to be disassembled for cleaning or replacement. The operation is cumbersome and time-consuming, which significantly increases the downtime maintenance cost and downtime of the air conditioning system (especially since the shutdown of commercial air conditioning will affect the normal cooling / heating demand of the building). Utility Model Content

[0004] The purpose of this utility model is to provide a horizontal oil separator to solve the problem mentioned in the background art that some existing horizontal oil separators still have high maintenance difficulty of filter components in actual applications of air conditioning systems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a horizontal oil separation container, comprising a container body and a sealing cover movably connected to the container body, characterized in that: a support base one and a support base two are fixed at the bottom of the container body, a positioning ring movably connected to the container body is fixed on one outer wall of the sealing cover, a guide plate is fixed on the top wall of the inner cavity of the positioning ring, and a filter plate is installed inside the positioning ring, and positioning blocks movably connected to the support base one are fixed on both outer walls of the sealing cover; The second support base has two mounting slots on one side of its outer wall. A drive motor is installed in the mounting slot, and a guide screw is fixed to the output end of the drive motor. The outer wall of the guide screw is threaded with a connecting sleeve that is fixedly connected to the positioning block. The first support base has two moving holes for the connecting sleeve to move.

[0006] In a further embodiment, a feed pipe is fixed to the upper half of the sealing cover, and a groove is provided on the outer wall of the positioning ring, with a sealing ring fixed inside the groove.

[0007] In a further embodiment, the inner wall of the container body is provided with multiple fixing grooves, and electric heating tubes are installed in the fixing grooves. A water outlet pipe and a sewage discharge pipe are respectively installed at the bottom of the container body, and a control valve is installed on both the water outlet pipe and the sewage discharge pipe.

[0008] In a further embodiment, a plurality of oil outlets are provided on one outer wall of the container body, an oil outlet pipe is installed in the oil outlet, a solenoid valve is installed on the oil outlet pipe, and a plurality of liquid level sensors corresponding to the positions of the oil outlet pipes are installed on the inner wall of the container body.

[0009] In a further embodiment, limit rods are fixed on both outer walls of the connecting sleeve, a limit groove is provided on the support base for the limit rods to move, and a limit ring is fixed on the outer wall of the connecting sleeve.

[0010] The technical effects and advantages of this utility model are as follows: This horizontal oil separator container, through the cooperation of a drive motor, a guide screw and a connecting sleeve, can achieve rapid opening and closing of the sealing cover and the container body. Starting the drive motor will drive the guide screw to rotate, causing the connecting sleeve to move along the moving hole, thereby opening the sealing cover. The filter plate can be removed without disassembling the complex structure, which greatly shortens the downtime maintenance time of the air conditioning system, and is especially suitable for commercial air conditioning with high maintenance efficiency requirements. The guide plate inside the positioning ring is designed for the refrigerant flow rate discharged from the air conditioning compressor. It can effectively slow down the instantaneous flow rate of refrigerant entering the container and avoid the refrigerant and refrigeration oil separation disorder caused by flow rate fluctuations. At the same time, the filter plate can not only trap metal debris and pipeline oxidation impurities generated by compressor wear, but also adsorb trace contaminants in the refrigeration oil, ensuring the cleanliness of the oil entering the compressor and reducing component wear. The electric heating element in the fixed groove on the inner wall of the container can be automatically activated in low-temperature environments. When used in low-temperature or cold regions during winter, it can automatically and moderately heat the refrigeration oil, effectively preventing the separation efficiency from decreasing and the oil return from being obstructed due to oil solidification or increased viscosity. This also broadens the applicable ambient temperature range of the air conditioning system. This horizontal oil separation container can reduce liquid disturbance, improve oil separation accuracy, and facilitate the disassembly and maintenance of the filter plate.

[0014] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0015] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0016] This utility model provides, for example Figure 1-5The horizontal oil separator shown includes a container body 1 and a sealing cover 4 movably connected to the container body 1. The bottom of the container body 1 is fixed with a support base 2 and a support base 3. A positioning ring 5 movably connected to the container body 1 is fixed to one outer wall of the sealing cover 4. The outer wall of the positioning ring 5 has a groove, and a sealing ring 6 is fixed in the groove to ensure the sealing between the container body 1 and the positioning ring 5. The upper half of the sealing cover 4 is fixed with a feed pipe 7, which is adapted to the exhaust pipe of the air conditioning compressor. The top wall of the inner cavity of the positioning ring 5 is fixed with a guide plate 8. The guide plate 8 has an arc-shaped structure. When the oily liquid enters the positioning ring 5 through the feed pipe 7, the guide plate 8 can slow down the liquid flow rate and prevent the liquid from directly impacting the inside of the positioning ring 5, causing oil-water separation disorder, and providing a stable initial environment for subsequent separation. A filter plate 9 is installed inside the positioning ring 5. From left to right, a coarse fiber filter layer, a fine fiber filter layer, and an activated carbon adsorption layer are arranged inside the filter plate 9. All of them are installed inside the filter plate 9 by a detachable fixing frame. The coarse fiber filter layer can filter larger particulate impurities in the liquid, the fine fiber filter layer further intercepts small oil droplets, and the activated carbon adsorption layer adsorbs residual trace oil and odors. The separation accuracy and efficiency are improved through multi-stage filtration. The detachable fixing frame design facilitates the replacement and cleaning of the filter layer and reduces maintenance costs. Positioning blocks 10 that are movably connected to the support base 2 are fixed on both outer walls of the sealing cover 4. The inner wall of the container body 1 has multiple fixed grooves, and electric heating tubes 11 are installed in the fixed grooves. The electric heating tubes 11 can heat the liquid in the container body 1 when the temperature is low to prevent the oil from solidifying. Temperature sensors (not shown in the figure) can be installed at appropriate positions on the inner wall of the container body 1 to detect the real-time temperature inside the container body 1. Water outlet pipe 12 and sewage pipe 13 are installed at the bottom of the container body 1, and control valves are installed on both the water outlet pipe 12 and the sewage pipe 13. Multiple oil outlets are opened on one side of the outer wall of the container body 1, and oil outlet pipes 14 are installed in the oil outlets. The oil outlet pipes 14 are adapted to the return oil pipe of the compressor. Solenoid valves are installed on the oil outlet pipes 14. Multiple liquid level sensors 15 corresponding to the positions of the oil outlet pipes 14 are installed on the inner wall of the container body 1. The multi-height oil outlet pipes 14, together with the liquid level sensors 15, can flexibly select the oil outlet according to the oil layer thickness to avoid incomplete oil discharge or oil carried in the drainage, thereby reducing resource waste and environmental pollution. Two mounting slots are provided on one side of the outer wall of the support base 2 3. A drive motor 16 is installed in the mounting slot, and a guide screw 17 is fixed to the output end of the drive motor 16. A connecting sleeve 18, which is fixedly connected to the positioning block 10, is threaded to the outer wall of the guide screw 17. Two moving holes are provided on the support base 1 2 for the connecting sleeve 18 to move. Limiting rods 19 are fixed on both sides of the outer wall of the connecting sleeve 18. Limiting slots are provided on the support base 1 2 for the limiting rods 19 to move. The limiting rods 19 can restrict the movement path of the connecting sleeve 18 when the drive motor 16 drives the guide screw 17 to rotate. A limiting ring 20 is fixed to the outer wall of the connecting sleeve 18. The limiting ring 20 can limit the movement distance of the connecting sleeve 18 to avoid the connecting sleeve 18 moving too far, which would damage the guide screw 17. By moving the connecting sleeve 18, the sealing cover 4 and the positioning ring 5 can be quickly separated from the container body 1, making it convenient for the sealing cover 4 to be opened and for the staff to clean and replace the multiple filter layers in the filter plate 9.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0018] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Working principle: In this horizontal oil separator, the high-temperature, high-pressure oil-containing refrigerant discharged from the air conditioning compressor is injected into the container through the feed pipe 7 on the sealing cover 4, which is adapted to the compressor exhaust pipe. After the liquid enters the positioning ring 5, the flow rate is slowed down by the buffering effect of the arc-shaped guide plate 8 to avoid violent disturbance. Then the liquid flows through the filter plate 9, and successively passes through the coarse fiber filter layer to intercept larger solid impurities, the fine fiber filter layer to capture dispersed fine oil droplets, and the activated carbon adsorption layer to adsorb trace amounts of oil and odors, thus completing the preliminary filtration and oil-liquid pre-separation. After preliminary treatment, the liquid enters the container body 1. If the ambient temperature of the air conditioning system is low, the electric heating tube 11 on the inner wall of the container body 1 will automatically start to heat the liquid appropriately to maintain the fluidity of the oil and ensure that the oil-water separation is carried out smoothly. As the liquid settles and separates in the container body 1, the liquid level sensor 15 at different heights will detect the thickness of each layer of oil in real time. When the oil layer at a certain height reaches the set thickness, the control system will trigger the solenoid valve on the corresponding height oil outlet pipe 14 to open. The separated oil will flow back to the compressor through the oil outlet pipe 14. After the oil return is completed, the control valve on the water outlet pipe 12 will be opened to drain the water in the lower layer. If impurities accumulate at the bottom of the container, they can be cleaned through the control valve on the drain pipe 13. When maintenance of the filter plate 9 is required, start the drive motor 16 on the support base 2 3. The drive motor 16 drives the guide screw 17 to rotate. The connecting sleeve 18, which is threaded to the guide screw 17, moves along the moving hole under the guidance of the limit rod 19 and the limit groove, thereby causing the positioning block 10 and the sealing cover 4 to separate from the container body 1. At this time, the filter plate 9 inside the positioning ring 5 can be taken out to clean or replace the internal filter medium. After maintenance is completed, start the drive motor 16 in reverse to reset the sealing cover 4. The sealing ring 6 on the positioning ring 5 ensures the sealing between the container body 1 and the sealing cover 4, and the equipment can be put into oil-liquid separation operation again.
