Description

Technical Field

[0001] This invention relates to the field of filter technology, and in particular to a flow-guiding ring tunnel filter. Background Technology

[0002] During battery manufacturing, the batteries need to be charged. The heat generated during charging raises the temperature of the electrolyte, causing it to expand and overflow from the filling port. To prevent this overflowing electrolyte from spreading onto the battery casing surface, a negative pressure cup is typically used to collect it. In use, the negative pressure cups are arranged at intervals on a collection rack. The inlet of each negative pressure cup is connected to one of the lithium batteries arranged at intervals, and the outlet is connected to a manifold located on the collection rack, from which the electrolyte then enters a gas-liquid separator for gas-liquid separation.

[0003] Currently used gas-liquid separators typically consist of several major components: a valve seat, a separation cylinder, a filter element, and a liquid storage tank. Among these, the filter element is the most crucial component. Because the electrolyte gas contains a large number of electrolyte droplets, current gas-liquid separators are not only structurally complex but also have low gas-liquid separation efficiency and incomplete separation.

[0004] A tunnel-type filter element with a guide ring, disclosed in announcement number CN118267800B, comprises: a filter element including a filter element body, an exhaust port, a gas-liquid separation component one, a gas-liquid separation component two, and a gas-liquid separation component three; a guide ring having several air inlet holes; and a tank through which the gas-liquid mixture enters the first chamber. In this tunnel-type filter element, the gas-liquid mixture passes through the guide ring, causing the circulating flow to collide with the inner wall of the separator, where liquid condenses on the inner wall of the tank. Gas converges within the filter element's internal cavity. As the gas flow passes through the first, second, and third gas-liquid separation components, it overlaps with the through-holes. Because the through-holes are misaligned, the gas flow continuously collides with the inner walls of the first, second, and third gas-liquid separation components, slowing the condensation process. Finally, the gas converges at the third gas-liquid separation component and is discharged.

[0005] The above technical solution can effectively separate gas and liquid. However, ensuring the stability of the filter element position to guarantee the directional flow of gas and liquid is a difficult problem for the filter element to perform stable separation and filtration operations, so improvements are needed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flow-guiding ring tunnel filter element.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A flow guide ring tunnel filter element includes a gas-liquid separation filter element. The gas-liquid separation filter element has two second semi-circular protective tubes on both sides of its horizontal end. A first semi-circular protective tube is fixed to the upper end of each of the two second semi-circular protective tubes. The gas-liquid separation filter element is located between the two second semi-circular protective tubes and the two first semi-circular protective tubes. Each of the two first semi-circular protective tubes has an arc-shaped notch, which is positioned opposite to each other. An adjustment clamping mechanism is provided between the two arc-shaped notches. The adjustment clamping mechanism has a second semi-circular ring, which is slidably installed at the lower end of one of the first semi-circular protective tubes. The lower ends of the second semicircular ring are provided with linkage mechanisms on both sides. The linkage mechanism is provided with a linkage shaft, and one end of the linkage shaft is provided with a pressing mechanism. The pressing mechanism is provided on the two second semicircular protective tubes. Two second semicircular protective tubes are each rotatably fitted with a third semicircular ring. The third semicircular ring is provided with a synchronous abutment mechanism. The synchronous mechanism is provided with an abutment plate. The two abutment plates abut against the two sides of the horizontal end of the gas-liquid separator filter element, respectively. One of the synchronous abutment mechanisms is provided with a lifting rod. The lifting rod is located at the lower end of one of the linkage mechanisms.

[0008] Compared with the prior art, the present invention can effectively cover the gas-liquid separation filter element by the cooperation of two first semi-circular protective tubes and two arc-shaped notches. At the same time, through the function of the filter element sealing ring, it is ensured that the electrolyte must flow in a directional manner through the gas-liquid separation filter element, that is, the gas-liquid separation operation can be completed by the second semi-circular protective tube.

[0009] Preferably, the adjusting clamping mechanism includes a screw rotatably installed in one of the arc-shaped notches, a first semi-circular ring threaded onto the screw, the first semi-circular ring abutting against the side wall of the arc-shaped notch, two nuts threaded onto the upper end of the screw, the two nuts being respectively located at both ends of the first semi-circular ring, a closing abutting mechanism being provided on the first semi-circular ring, two spring members being fixed together with the bottom of the first semi-circular ring and one of the arc-shaped notches, inclined rods being fixed on both sides of the lower end of the first semi-circular ring, and grooves being provided on both sides of the lower end of the other arc-shaped notch, the lower ends of the two inclined rods extending into the two grooves respectively.

[0010] Furthermore, by controlling the rotation direction of the screw, the first semicircular ring can be stably raised and lowered. As the first semicircular ring rises and falls, the closing contact mechanism can be controlled, controlling whether the protective cover can rotate. At the same time, by moving the inclined rod downward, the two first semicircular protective tubes can move relative to each other, effectively covering the gas-liquid separation filter element. Simultaneously, in conjunction with the corresponding sealing components, the sealing effect is ensured, so that the separated gas and liquid can only be discharged through the corresponding positions.

[0011] Preferably, an abutting shaft is installed in the groove, and the inclined rod abuts against the abutting shaft.

[0012] Furthermore, it facilitates the downward movement of the inclined rod, thereby improving the relative movement quality of the two first semicircular protective tubes.

[0013] Preferably, the closed contact mechanism includes two columns fixed to one side of the first semi-circular ring, with a protective cover plate hinged to the upper end of one of the arc-shaped notches. A contact plate is provided on one side of the protective cover plate and at the upper end of the two columns. One contact plate is fixedly connected to the protective cover plate, and the other contact plate is fixed to the upper end of the two columns.

[0014] Furthermore, the lifting and lowering of the first semicircular ring can drive the column and the contact plate fixed on the column to rise and fall. When the contact plate descends, it can separate the two contact plates, making it easier for the protective cover to rotate. When the two contact plates collide, it can prevent the protective cover from rotating.

[0015] Preferably, the linkage mechanism includes two pressure rods fixed on both sides of the lower end of the second semicircular ring. A square frame is fixed to the lower end of each pressure rod. A rotating shaft is installed inside the square frame. Support frames are fixed on both sides of the upper end of the second semicircular protective tube at the lower end of the second semicircular ring. The two linkage shafts are respectively rotatably sleeved on the two support frames. A swing rod is fixed to one side of the linkage shaft. One end of the rotating shaft is rotatably sleeved on the swing rod on the same side. The upper end of the lifting rod is located at the lower end of one of the swing rods.

[0016] Furthermore, as the first semicircular ring descends, the second semicircular ring descends, causing the pressure rod to push the square frame to descend. Through the descent of the square frame, the rotating shaft can move within the square frame, causing the swing arm to drive the linkage shaft to rotate, enabling the extrusion mechanism to operate and ensuring that the two first semicircular protective tubes and the two arc-shaped notches fully collide. With the cooperation of the corresponding components, a squeeze seal can be achieved to avoid leakage and ensure that gas-liquid separation is completed within the two second semi-circular protective pipe fittings.

[0017] Preferably, the extrusion mechanism includes two U-shaped frames fixed on both sides of the upper end of another second semi-circular protective tube. One end of each of the two linkage shafts passes through the U-shaped frame and extends to one side of the U-shaped frame. A rotating rod is fixed to one end of the linkage shaft extending out of the U-shaped frame. A shaft sleeve is rotatably sleeved on the rotating rod. The shaft sleeve abuts against the U-shaped frame.

[0018] Furthermore, as the linkage shaft rotates, it can drive the rotating rod and shaft assembly to deflect, and at the same time, it can also cause the shaft assembly and the U-shaped frame to come into contact, causing the shaft assembly to rotate and the two arc-shaped notches to move relative to each other, increasing the mutual squeezing force and ensuring the firmness of the connection.

[0019] Preferably, the synchronous contact mechanism includes a push rod connected to the third semicircular ring, the contact plate being slidably installed inside the corresponding second semicircular protective tube, one end of the third semicircular ring and one end of the contact plate being rotatably connected, one end of the push rod being rotatably connected to one side of the contact plate, the two contact plates being located on both sides of the gas-liquid separation filter element, and a pull rod being rotatably connected to the top of one of the third semicircular rings, the lower end of the pull rod being fixed with a pin, one end of the pin being rotatably sleeved on the lower end of the lifting rod, the lower end of the lifting rod being located inside the second semicircular protective tube.

[0020] Furthermore, when the linkage shaft drives the swing arm to deflect, the swing arm will press the lifting rod, causing the lifting rod to drive the third semi-circular ring to deflect via the pull rod. This third semi-circular ring will push another third semi-circular ring to rotate, allowing the third semi-circular ring to push the contact plate to move via the push rod. This allows the two contact plates to clamp the gas-liquid separation filter element, limiting the positional relationship between the two second semi-circular protective tubes and the gas-liquid separation filter element, ensuring the overall stability.

[0021] Preferably, sealing rubber gaskets are fixed on the inner walls of both the arc-shaped notch and the second semi-circular protective pipe fitting; A pressure monitoring device is sealed between the two first semicircular protective pipe fittings.

[0022] Furthermore, the sealing rubber gaskets can be squeezed together and easily deformed, effectively ensuring the sealing effect; at the same time, the gas situation inside can be understood in order to understand the gas-liquid separation.

[0023] Preferably, both ends of the second semicircular protective tube are fixed with abutting rubber rings, and the lower ends of the two second semicircular protective tubes are hinged to each other.

[0024] Furthermore, the action of the rubber ring can clamp the horizontal end of the gas-liquid separator filter element, thus initially ensuring the relative positional relationship between the second semi-circular protective tube and the gas-liquid separator filter element.

[0025] Preferably, both ends of the gas-liquid separation filter element are fixed with filter element sealing rings, and the filter element sealing rings abut against the second semi-circular protective tube.

[0026] Furthermore, through the contact between the filter element sealing ring and the second semi-circular protective tube, the gas-liquid separation filter element is in contact with the outside at both ends, while the other parts are located inside the second semi-circular protective tube. This ensures that gas-liquid separation takes place inside the second semi-circular protective tube, thereby controlling the flow direction of gas and liquid.

[0027] The beneficial effects of this invention are: 1. By controlling the rotation direction of the screw, the first semicircular ring can be stably raised and lowered. As the first semicircular ring rises and falls, the closing contact mechanism can be controlled, and the protective cover can be rotated. At the same time, by the downward movement of the inclined rod, the two first semicircular protective tubes can move relative to each other, effectively covering the gas-liquid separation filter element. Furthermore, through the cooperation of the filter element closing ring and the second semicircular protective tube, the contact seal at both ends is achieved, meaning that the electrolyte to be filtered can only enter between the two second semicircular protective tubes through the gas-liquid separation filter element. 2. It facilitates the downward movement of the inclined rod, allowing the two first semi-circular protective tubes to move relative to each other. At the same time, the inclined rod is set at an angle, and its hemispherical shape allows it to quickly contact the contact shaft, so that the inclined rod can be inserted into the groove. 3. The lifting and lowering of the first semi-circular ring can drive the column and the contact plate fixed on the column to rise and fall. When the contact plate descends, it can separate the two contact plates, making it easier for the protective cover to rotate. When the two contact plates collide, it can prevent the protective cover from rotating. 4. As the first semicircular ring descends, the second semicircular ring descends, causing the pressure rod to push the square frame to descend. The descent of the square frame allows the rotating shaft to move within the square frame, causing the swing arm to drive the linkage shaft to rotate, thus enabling the extrusion mechanism to operate and ensuring that the two first semicircular protective tubes and the two arc-shaped notches fully contact each other. 5. As the linkage shaft rotates, it can drive the rotating rod and shaft assembly to deflect. At the same time, it can also cause the shaft assembly and the U-shaped frame to come into contact, which can cause the shaft assembly to rotate and the two arc-shaped notches to move relative to each other, increasing the mutual squeezing force and ensuring the firmness of the connection. 6. When the linkage shaft drives the swing arm to deflect, the swing arm will squeeze the lifting rod, which will cause the lifting rod to drive the third semi-circular ring to deflect through the pull rod. This third semi-circular ring will push another third semi-circular ring to rotate, which will cause the third semi-circular ring to push the contact plate to move through the push rod. This will allow the two contact plates to clamp the gas-liquid separation filter element, limiting the positional relationship between the two second semi-circular protective tubes and the gas-liquid separation filter element, ensuring the overall firmness, so as to ensure that the electrolyte needs to flow through the gas-liquid separation filter element. By contacting the filter element's sealing ring and the second semi-circular protective tube, the gas-liquid separation filter element's two ends are in contact with the outside, while the other parts are located inside the second semi-circular protective tube. This ensures that gas-liquid separation takes place inside the second semi-circular protective tube, thereby controlling the flow direction of gas and liquid. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-6 A flow-guiding ring tunnel filter element includes a gas-liquid separation filter element 1, which is an existing component. The gas-liquid mixture passes through the flow-guiding ring, causing the circulating flow to collide with the inner wall of the gas-liquid separator. The liquid condenses on the inner wall of the tank, and the gas enters the internal cavity of the filter element and then flows out in a concentrated manner, which does not need to be disclosed again. The gas-liquid separation filter element 1 has a second semi-circular protective tube 21 on both sides of its horizontal end. Both ends of the second semi-circular protective tube 21 are fixed with abutting rubber rings 32. The lower ends of the two second semi-circular protective tubes 21 are hinged to each other. The abutting rubber rings 32 can clamp the horizontal end of the gas-liquid separation filter element 1 to initially ensure the relative positional relationship between the second semi-circular protective tube 21 and the gas-liquid separation filter element 1. Both ends of the gas-liquid separator filter element 1 are fixed with filter element sealing rings 33, which abut against the second semi-circular protective tube 21. Through this contact, the ends of the gas-liquid separator filter element 1 are in contact with the outside, while the rest of the filter element is located inside the second semi-circular protective tube 21. This ensures that gas-liquid separation occurs within the second semi-circular protective tube 21, allowing control of the gas and liquid flow direction. Specifically, how the separated gas and liquid are discharged is determined by adding a gas flow pipeline to the upper end of the two second semi-circular protective tubes 21, on the side where the pressure monitoring device 34 is installed, to output the separated gas. The separated liquid can be discharged through the other end of the two second semi-circular protective tubes 21. The upper ends of the two second semicircular protective tubes 21 are each fixed with a first semicircular protective tube 3. The gas discharge pipe can be installed on one side of the upper end of the first semicircular protective tube 3. The gas-liquid separation filter element 1 is located between the two second semicircular protective tubes 21 and the two first semicircular protective tubes 3. The first semicircular protective tubes 3 and the second semicircular protective tubes 21 are both made of corrosion-resistant materials, which helps to extend the service life and better separate the electrolyte into gas and liquid. The two first semicircular protective tubes 3 are each provided with an arc-shaped notch 4. The two arc-shaped notches 4 are arranged opposite each other and can form a ring structure through the two arc-shaped notches 4, which facilitates the installation of corresponding components in the ring structure, thus completing the firm connection between the two second semicircular protective tubes 21 and the two first semicircular protective tubes 3. Sealing rubber gaskets 5 are fixed on the inner walls of the arc-shaped notches 4 and the second semicircular protective tubes 21. The sealing rubber gaskets 5 can squeeze each other and are easy to deform, effectively ensuring the sealing effect.

[0031] Reference Figure 1-4An adjusting clamping mechanism is provided between the two arc-shaped notches 4. The adjusting clamping mechanism has a second semi-circular ring 9, which is slidably installed at the lower end of one of the first semi-circular protective pipe fittings 3. The adjusting clamping mechanism includes a screw 23 rotatably installed within one of the arc-shaped notches 4. A first semi-circular ring 6 is threaded onto the screw 23, and the first semi-circular ring 6 abuts against the side wall of the arc-shaped notch 4. Two nuts 22 are threaded onto the upper end of the screw 23, and the two nuts 22 are respectively located at both ends of the first semi-circular ring 6. A closing abutment mechanism is provided on the first semi-circular ring 6. The first semi-circular ring 6 and the bottom of one of the arc-shaped notches 4 are jointly fixed with two... A spring component 24, with inclined rods 7 fixed on both sides of the lower end of the first semicircular ring 6, and grooves 8 opened on both sides of the lower end of the other arc-shaped notch 4, with the lower ends of the two inclined rods 7 extending into the two grooves 8 respectively; by controlling the rotation direction of the screw 23, the first semicircular ring 6 can be raised and lowered stably. As the first semicircular ring 6 rises and falls, the closing contact mechanism can be controlled, and the protective cover plate 2 can be controlled to rotate. At the same time, by moving the inclined rods 7 downward, the two first semicircular protective tubes 3 can be moved relative to each other, effectively covering the gas-liquid separation filter element 1; controlling the flow direction of the separated gas and liquid, and enabling the electrolyte to flow in a directional manner; An abutting shaft 25 is installed in the groove 8, and the inclined rod 7 abuts against the abutting shaft 25; the lower end of the inclined rod 7 is hemispherical; the inclined rod 7 is inclined, and the hemispherical shape allows it to quickly abut against the abutting shaft 25 so that the inclined rod 7 can be inserted into the groove 8.

[0032] Reference Figure 2-4 The closed contact mechanism includes two columns 20 fixed to one side of the first semicircular ring 6. A protective cover plate 2 is hinged to the upper end of one of the arc-shaped notches 4. A contact plate 19 is provided on one side of the protective cover plate 2 and at the upper end of the two columns 20. One contact plate 19 is fixedly connected to the protective cover plate 2, and the other contact plate 19 is fixed to the upper end of the two columns 20. The lifting and lowering of the first semicircular ring 6 can drive the columns 20 and the contact plate 19 fixed on the columns 20 to lift and lower. When the contact plate 19 is lowered, the two contact plates 19 can be separated, which makes it easier for the protective cover plate 2 to rotate. When the two contact plates 19 collide, the protective cover plate 2 cannot be rotated.

[0033] Reference Figure 2-6The lower ends of the second semicircular ring 9 are provided with linkage mechanisms on both sides. Each linkage mechanism has a linkage shaft 15. The linkage mechanism includes two pressure rods 10 fixed to the lower ends of the second semicircular ring 9. A square frame 11 is fixed to the lower end of each pressure rod 10, and a rotating shaft 12 is installed inside the square frame 11. Support frames 13 are fixed to the upper ends of the second semicircular protective tube 21 located at the lower end of the second semicircular ring 9 on both sides. The two linkage shafts 15 are rotatably sleeved on the two support frames 13 respectively. A swing rod 14 is fixed to one side of each linkage shaft 15. One end of the rotating shaft 12 is rotatably sleeved on the swing arm 14 on the same side, and the upper end of the lifting rod 26 is located at the lower end of one of the swing arms 14; as the first semicircular ring 6 descends, the second semicircular ring 9 descends, causing the pressure rod 10 to push the square frame 11 to descend. Through the descent of the square frame 11, the rotating shaft 12 can move within the square frame 11, causing the swing arm 14 to drive the linkage shaft 15 to rotate, enabling the extrusion mechanism to operate and ensuring that the two first semicircular protective tubes 3 and the two arc-shaped notches 4 fully collide.

[0034] Reference Figure 2-6 One end of the linkage shaft 15 is provided with a pressing mechanism, which is set on two second semi-circular protective tubes 21. The pressing mechanism includes two U-shaped frames 16 fixed on both sides of the upper end of another second semi-circular protective tube 21. One end of each linkage shaft 15 passes through the U-shaped frame 16 and extends to one side of the U-shaped frame 16. A rotating rod 17 is fixed to one end of the linkage shaft 15 extending out of the U-shaped frame 16. A shaft assembly 18 is rotatably sleeved on the rotating rod 17. The shaft assembly 18 and the U-shaped frame 16 abut against each other. As the linkage shaft 15 rotates, it can drive the rotating rod 17 and the shaft assembly 18 to deflect. At the same time, it can also make the shaft assembly 18 and the U-shaped frame 16 abut against each other, which can make the shaft assembly 18 rotate, so that the two arc-shaped notches 4 move relative to each other, increase the mutual pressing force, and ensure the firmness of the connection.

[0035] Reference Figure 2-6 Each of the two second semicircular protective tubes 21 has a third semicircular ring 29 rotatably fitted inside it. The third semicircular ring 29 is provided with a synchronous contact mechanism, and the synchronous mechanism is provided with a contact plate 31. The two contact plates 31 respectively abut against the two sides of the horizontal end of the gas-liquid separation filter element 1. One of the synchronous contact mechanisms is provided with a lifting rod 26, which is located at the lower end of one of the linkage mechanisms. In actual manufacturing, the two third semicircular rings 29 can form a ring. As one of the third semicircular rings 29 rotates, it can enter the other second semicircular protective tube 21. And through the action of the synchronous mechanism, the two contact plates 31 move towards the gas-liquid separation filter element 1, so as to effectively clamp the gas-liquid separation filter element 1 and fix its position.

[0036] Reference Figure 2-6The synchronous contact mechanism includes a push rod 30 connected to the third semicircular ring 29, and a contact plate 31 slidably installed inside the corresponding second semicircular protective tube 21. One end of the third semicircular ring 29 and the contact plate 31 are rotatably connected, and one end of the push rod 30 is rotatably connected to one side of the contact plate 31. The two contact plates 31 are located on both sides of the gas-liquid separation filter element 1. A pull rod 28 is rotatably connected to the top of one of the third semicircular rings 29. A pin 27 is fixed to the lower end of the pull rod 28. One end of the pin 27 is rotatably sleeved on the lower end of the lifting rod 26. The lower end of the lifting rod 26 is located at... Inside the second semicircular protective tube 21; when the linkage shaft 15 drives the swing rod 14 to deflect, the swing rod 14 will squeeze the lifting rod 26, which will cause the lifting rod 26 to drive the third semicircular ring 29 to deflect through the pull rod 28. The third semicircular ring 29 will push another third semicircular ring 29 to rotate, which will cause the third semicircular ring 29 to push the contact plate 31 to move through the push rod 30. This will allow the two contact plates 31 to clamp the gas-liquid separation filter element 1, limiting the positional relationship between the two second semicircular protective tubes 21 and the gas-liquid separation filter element 1, and ensuring the overall firmness.

[0037] In this invention, two second semi-circular protective tubes 21 and two first semi-circular protective tubes 3 are fitted onto the gas-liquid separation filter element 1. The operator can drive the screw 23 to rotate in the opposite direction, which can cause the first semi-circular ring 6 to descend, so that the column 20 can drive the contact plate 19 to descend, so that the two contact plates 19 can separate, making it easier for the protective cover plate 2 to rotate; The descent of the first semicircular ring 6 will cause the inclined rod 7 to insert into the groove 8, causing the two first semicircular protective tubes 3 to move relative to each other; Simultaneously, the descent of the first semicircular ring 6 will push the second semicircular ring 9 to descend, which in turn will push the pressure rod 10 to cause the square frame 11 to descend. The rotating shaft 12 will cause the swing rod 14 to drive the linkage shaft 15 to rotate, and the shaft assembly 18 will abut against the U-shaped frame 16, causing the two second semicircular protective tubes 21 and the two arc-shaped notches 4 to abut against each other, squeezing the sealing rubber gasket 5 for effective sealing. At the same time, the abutting rubber ring 32 will abut against the horizontal end of the gas-liquid separation filter element 1, limiting the positional relationship between the gas-liquid separation filter element 1 and the second semicircular protective tube 21. Simultaneously, as the swing arm 14 deflects, the lifting rod 26 can be lowered. The lifting rod 26 drives the third semi-circular ring 29 to rotate through the pull rod 28. This third semi-circular ring 29 will abut against another third semi-circular ring 29 to operate, which can cause the push rod 30 to push the contact plate 31 to move towards the gas-liquid separation filter element 1, effectively achieving the clamping of the gas-liquid separation filter element 1. Meanwhile, through the contact between the filter element sealing ring 33 and the two ends of the second semi-circular protective tube 21, the gas-liquid separation filter element 1 is able to contact the outside at both ends, while the other parts are located inside the second semi-circular protective tube 21. This ensures that gas-liquid separation takes place inside the second semi-circular protective tube 21, so as to control the flow direction of gas and liquid.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
