Description

Technical Field

[0001] This utility model belongs to the field of compressors, and in particular relates to a mixing structure for a gas-liquid mixing compressor and a compressor having the same. Background Technology

[0002] A gas-liquid mixing compressor is a device that mixes and compresses gas and liquid, and is widely used in chemical, petroleum, natural gas, environmental protection and other fields. However, existing gas-liquid mixing compressors have some technical problems in actual operation, the most prominent of which is that they are prone to clogging, leading to insufficient intake pressure.

[0003] During the operation of a gas-liquid mixing compressor, liquid and gas enter the compressor through pipes. Due to the incompressibility of liquids and the complexity of gas-liquid mixtures, liquids tend to accumulate in pipes or filters, forming liquid films or blockages. For example, in a BOG compressor, due to the increase in heavy components in the mixed gas, these gaseous components easily condense into liquid at low temperatures, clogging the pores and increasing the pressure difference before and after the filter, resulting in a decrease in the compressor inlet pressure.

[0004] When a blockage occurs, the gas pressure decreases, the mixing effect between the gas and liquid becomes worse, and a large number of bubbles are easily generated at the compressor impeller, leading to gas resistance and further reducing the pressure of the entire fluid. Summary of the Invention

[0005] In view of this, the present invention aims to propose a mixing structure for a gas-liquid mixing compressor and a compressor having the same, so as to solve the problems of traditional gas-liquid mixing compressors being prone to inlet blockage, low gas-liquid mixing efficiency and easy generation of air resistance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of the present invention, a mixing structure for a gas-liquid mixing compressor is provided, comprising:

[0007] The outer casing has an open end on one side for connecting to the compressor chamber, and an anti-blocking connection part is coaxially provided on the other side wall, wherein the peripheral wall of the anti-blocking connection part is provided with several deflection parts;

[0008] The intake pipe has its outlet end inserted into the anti-clogging connection part.

[0009] The flow-gathering and anti-fouling section is installed on the outer wall of the anti-clogging connection section. After the gas enters the anti-clogging connection section through the inlet pipe, it is redirected by the diversion section and flows along the inner wall of the flow-gathering and anti-fouling section to the cavity where the compressor impeller is located. The outer shell is provided with a fluid inlet end, which is used to guide the fluid to flow along the outer wall of the flow-gathering and anti-fouling section and finally merge with the gas.

[0010] Furthermore, the anti-blocking connection part is rotatably connected to the impeller at the end near the compressor compression chamber.

[0011] Furthermore, all the gas ejected from the redirecting section forms a swirling flow.

[0012] Furthermore, an intake check valve is provided at the outlet end of the intake pipe.

[0013] Furthermore, a filter assembly is provided at the inlet end of the air intake pipe, and several filter elements are provided in the filter assembly. When any filter element is connected to the air intake pipe, the other filter elements are disconnected from the air intake pipe. The filter assembly is provided with a filter element extraction component for removing used filter elements.

[0014] Furthermore, the filter assembly includes a filter housing connected to the air intake pipe, a support part rotatably connected inside the filter housing, an adjustment part connected to the support part and extending one end out of the filter housing for rotating the support part, a plurality of filter element receiving cavities disposed on the end face of the support part for accommodating each filter element, and a sealing part for closing or opening the opening on the filter housing for removing the waste filter element. The filter element extraction assembly is connected to the sealing part, and the filter element extraction assembly is used to couple with the waste filter element when in operation and pull it out from the corresponding filter element receiving cavity.

[0015] Furthermore, the sealing part is threadedly connected to the filter housing opening, and when the filter element extraction assembly is rotated, it drives the sealing part to rotate relative to the filter housing.

[0016] Furthermore, the filter cartridge extraction assembly includes a gripping part, a connecting part, an elastic element, a sliding part, and a coupling part. The gripping part is connected to the connecting part, and a sliding part is provided on the side of the connecting part away from the gripping part. The sliding part slidably passes through the sealing part and is connected to the coupling part. An elastic element is provided between the connecting part and the sealing part. The coupling part is used to couple with the waste filter cartridge after the action.

[0017] Furthermore, the coupling part is a magnet, and the filter element is provided with metal corresponding to the position of the magnet.

[0018] According to another aspect of the present invention, a compressor is provided, comprising a mixing structure as described above for a gas-liquid mixing compressor.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This structure, through the setting of the flow-concentrating and anti-fouling section, allows gas to enter through the redirection section and flow inside the flow-concentrating and anti-fouling section to form an ejector jet. When liquid enters, it flows along the outer wall of the flow-concentrating and anti-fouling section. The ejector jet guides the liquid, which can accelerate the overall flow rate and mixing efficiency, reduce the power consumption of the compressor impeller, and at the same time, the liquid flows directly to the compressor impeller along the flow-concentrating and anti-fouling section after entering, which can reduce the impact of fluid impurities on the intake air, thereby reducing the probability of blockage and extending the effective service time and service life.

[0021] 2. This structure, by setting an impeller, can rotate in conjunction with the swirling flow formed by the gas. At the same time, the liquid will be drawn towards the center by the ejector, further accelerating the rotation efficiency of the impeller and the mixing efficiency. Meanwhile, the cutting effect of the impeller can reduce the generation of some bubbles and reduce the impact of air resistance.

[0022] 3. This structure, by setting up a filter cartridge extraction component and using multiple filter cartridges, enables quick replacement of filter cartridges during use. At the same time, the operation of removing the filter cartridges is convenient, reducing redundant operation steps and improving operation efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Referring to the accompanying drawings, this embodiment provides a mixing structure for a gas-liquid mixing compressor, comprising:

[0037] The outer casing 1 has an open end on one side for connecting to the compressor's compression chamber, and an anti-clogging connection part 2 coaxially arranged on the other side wall. The anti-clogging connection part 2 has several redirecting parts 3 on its circumferential wall. The outer casing 1 primarily serves to provide a mixing space for fluids and liquids and should meet structural strength and corrosion resistance requirements. On the side wall away from the open end, an air intake unit located in the center and liquid inlet pipes distributed circumferentially relative to the air intake unit are integrated. Specifically, a threaded hole is provided on this end face of the outer casing 1. The anti-clogging connection part 2 is a hollow shaft with redirecting parts 3 on its circumferential wall. These redirecting parts 3 are openings evenly distributed along the circumferential wall of the anti-clogging connection part 2. A boss is provided on the outer wall of the anti-clogging connection part 2, and a sealing ring is placed on the boss. During assembly, the anti-clogging connection part 2 is inserted into the outer casing 1 through the thread and connected to the outer casing 1. Finally, the sealing ring on the boss abuts against the inner wall of the outer casing 1, forming a sealed connection. The threaded portion protruding from the outer casing 1 can be fixed by using washers and nuts to secure the anti-clogging connection part 2.

[0038] The intake pipe 6 has its outlet end inserted into the anti-clogging connection part 2. The intake pipe 6 also has external threads on its outer wall and internal threads on the anti-clogging connection part 2. These threads are connected and sealed. The intake pipe 6, the anti-clogging connection part 2, and the outer casing 1 are designed as separate sealed connections, allowing for replacement in case of failure and preventing complete scrapping. Simultaneously, the gas introduced through the intake pipe 6 first enters the anti-clogging connection part 2 for buffering and pressure stabilization, and then is ejected from the redirection part 3, flowing along the inner wall of the flow-gathering and anti-fouling part 4 to form a stable vortex. This reduces bubble formation when mixing with liquids, mitigating the adverse effects of air resistance.

[0039] The concentrating and anti-fouling section 4 is installed on the outer wall of the anti-clogging connection section 2. Gas enters the anti-clogging connection section 2 through the inlet pipe 6, is redirected by the redirecting section 3, and then flows along the inner wall of the concentrating and anti-fouling section 4 towards the cavity where the compressor impeller is located. The outer shell 1 is provided with a fluid inlet end for guiding the fluid to flow along the outer wall of the concentrating and anti-fouling section 4 and ultimately merge with the gas. The concentrating and anti-fouling section 4 is generally conical in shape, covering the area where the redirecting section 3 is located. This prevents backflow of liquid from affecting the redirecting section 3 when gas and liquid flow through it. Simultaneously, the concentrating and anti-fouling section 4 can form a stable swirling flow, which, in conjunction with the ejection effect of the redirecting section 3, guides the liquid, accelerating the overall flow rate and mixing efficiency of the liquid and gas.

[0040] In this embodiment, the anti-clogging connection 2 is rotatably connected to the impeller 5 near the compressor compression chamber. The impeller 5 is specifically located outside the opening side of the flow-gathering and anti-fouling section 4. As the gas exits from the flow-gathering and anti-fouling section 4, it forms a swirling flow that drives the impeller 5 to rotate. The impeller will guide the gas flow towards the liquid in the middle part and accelerate it a second time. The shearing action formed by the rotation will reduce the bubble rate, and the secondary acceleration will counteract the effect of gas resistance.

[0041] In this embodiment, an intake check valve 7 is provided at the outlet end of the intake pipe 6. This is to prevent liquid backflow and stabilize the outlet pressure.

[0042] In this embodiment, a filter assembly is provided at the inlet end of the air intake pipe 6. The filter assembly contains several filter elements 9. When any filter element 9 is connected to the air intake pipe 6, the other filter elements 9 are disconnected from the air intake pipe 6. The filter assembly is equipped with a filter element extraction component 10 for removing used filter elements. In this way, when a filter element in use becomes clogged, the position of the filter element 9 can be reversed to allow a new filter element to connect to the air intake pipe 6 for filtration. A sealing strip can be installed between the filter elements 9 to achieve a seal, thus ensuring airtightness while allowing for direct filter element replacement.

[0043] In this embodiment, the filter assembly includes a filter housing 12 connected to the air inlet pipe 6, a support portion 8 rotatably connected inside the filter housing 12, an adjustment portion 11 connected to the support portion 8 and extending one end out of the filter housing 12 for rotating the support portion 8, several filter element receiving cavities 13 disposed on the end face of the support portion 8 for accommodating each filter element 9, and a sealing portion 14 for closing or opening the opening on the filter housing 12 for removing the used filter element 9. The filter element extraction assembly 10 is connected to the sealing portion 14. The filter element extraction assembly 10 is used to couple with the used filter element 9 during operation and pull it out from the corresponding filter element receiving cavity 13. The support portion 8 is mainly used to support each filter element 9. Specifically, the support portion 8 is set in a disc shape, and a stepped through hole is provided on the side near the gas flow direction, so that after the filter element 9 is installed, it can form a stable connection with the countersunk hole under the action of airflow and will not fall off. The adjustment part 11 is used to rotate the adjustment support part 8, thereby adjusting the connection between different filter elements 9 and the air intake pipe 6. In this way, by adjusting and using multiple filter elements, the filter element replacement cycle can be extended. At the same time, the filter element can be replaced in the shortest time during normal use. The sealing part 14 is specifically set as a cover with internal threads and external threads at the opening of the filter housing 12, so that the sealing part 14 can be sealed when connected to it. The filter element extraction component 10 can not only remove the old filter element, but also act as a handle for the sealing part 14, improving convenience and reducing structural complexity.

[0044] In this embodiment, the sealing part 14 is threadedly connected to the opening of the filter shell 12, and when the filter element extraction assembly 10 is rotated, it is used to drive the sealing part 14 and the filter shell 12 to rotate relative to each other.

[0045] In this embodiment, the filter cartridge extraction assembly 10 includes a gripping part 10-1, a connecting part 10-2, an elastic element 10-3, a sliding part 10-4, and a coupling part 10-5. The gripping part 10-1 is connected to the connecting part 10-2. The sliding part 10-4 is provided on the side of the connecting part 10-2 away from the gripping part 10-1. The sliding part 10-4 slidably passes through the sealing part 14 and is connected to the coupling part 10-5. The elastic element 10-3 is provided between the connecting part 10-2 and the sealing part 14. The coupling part 10-5 is used to couple with the waste filter cartridge 9 after operation. The gripping part 10-1 may be provided with anti-slip texture for easy gripping. The sliding part 10-4 is specifically configured as a sliding rod. A corresponding opening is provided on the sealing part 14 so that the sliding rod can slide within the opening. To ensure uniform force distribution, two sliding rods are specifically configured, arranged symmetrically on both sides relative to the connecting part 10-2. The elastic element 10-3 is specifically configured as a spring, which is sleeved on each slide rod. The two ends of each spring abut against the connecting part 10-2 and the sealing part 14, respectively. When it is necessary to grasp the filter element 9, the gripping part 10-1 pushes the connecting part 10-2 to move closer to the filter element, and the sliding part 10-4 drives the coupling part 10-5 to move, thereby coupling with the filter element 9 and bringing the filter element 9 out of the corresponding countersunk hole. Then, the gripping part 10-1 is rotated, so that the sealing part 14 rotates and separates from the filter shell 12, and the waste filter element 9 is taken out.

[0046] In this embodiment, the coupling part 10-5 is a magnet, and the filter element 9 is provided with metal corresponding to the position of the magnet. If necessary, a male buckle can also be provided on the coupling part 10-5, and a female buckle on the filter element 9; the arrangement can be made reasonably according to actual needs.

[0047] According to another aspect of this utility model, a compressor is provided, including a mixing structure for a gas-liquid mixing compressor as described above. A flange hole is provided on the outer wall of the opening side of the housing 1 to connect with the compressor compression chamber.

[0048] In use, the filter housing 12 is connected to the air source at the inlet end and to the liquid inlet at the external fluid inlet end. At the same time, a one-way liquid inlet valve is set at the liquid inlet. When the compressor is running, a negative pressure is formed inside the housing 1, which allows the liquid and gas to enter the housing 1. After the gas enters the anti-clogging connection part 2, it will be buffered and stabilized. Finally, it will be blown out from the redirection part 3 and pass through the inner wall of the flow-gathering and anti-fouling part 4 to form a vortex. This will drive the impeller 5 to rotate, forming a secondary acceleration and entraining the liquid. After entering, the liquid flows along the outer wall of the flow-gathering and anti-fouling part 4 and is guided by the jet gas to flow towards the center. It passes through the impeller to accelerate the flow and reduce the generation of bubbles. After mixing and compression, it is pressurized and discharged by the compressor.

[0049] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
