Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manufacturing activated carbon filters, in particular to a filter material resistance testing tool for activated carbon filters. Background Art
[0002] Activated carbon filters are typically used to create a clean microenvironment. They capture dust and particles from gas-solid two-phase flows through the activated carbon, purifying the air. The activated carbon's resistance characteristics crucially impact its air purification performance and the amount of air removed per unit time. Failure to meet acceptance criteria will inevitably impact the final purification performance of the finished activated carbon filter. Therefore, prior to formal installation into the activated carbon filter, the entire batch of incoming materials must undergo a resistance test on a random basis. In a typical factory workshop, the general process for resistance testing is as follows: workers first compact the activated carbon granules into a test auxiliary tube. Next, they seal one end of the tube with an end cap (equipped with multiple microscopic air holes), assemble an adapter at the other end, and then pump high-pressure gas into the tube through the adapter. The pressure gauge attached to the adapter is immediately recorded, followed by a 30-second wait before recording the pressure gauge reading again. The difference between the two readings determines whether the activated carbon granules' resistance meets quality inspection standards. However, the aforementioned resistance testing method is cumbersome and labor-intensive. Furthermore, each test requires repeated disassembly and assembly of end caps and adapters, which is time-consuming and labor-intensive. Furthermore, the diameter of the auxiliary test tube varies depending on the type and specification of the activated carbon particles being tested, resulting in a wide variety of end caps and adapters. This poses a challenge for workers in finding the correct size of end caps and adapters immediately. Therefore, there is an urgent need for those skilled in the art to address these issues. Utility Model Content
[0003] Therefore, in view of the above-mentioned existing problems and defects, the development and design team of the present invention collected relevant information, conducted multiple evaluations and considerations, and continuously experimented and modified the tooling, which ultimately led to the emergence of the filter material resistance test tooling for activated carbon filters.
[0004] In order to solve the above-mentioned technical problems, the present invention relates to a filter material resistance testing tool for an activated carbon filter, comprising a base plate, a shelf, a pressing unit, a front plugging assembly, a rear plugging assembly, a power unit, an air charging unit, a first pressure gauge, a second pressure gauge and a test auxiliary tube. A through-shaped filling cavity for filling the activated carbon particles to be tested is provided in the test auxiliary tube. The shelf uses the base plate as an assembly base, and a V-shaped limit groove adapted to the outer diameter of the test auxiliary tube extends downward from its top wall. The pressing unit is used to press the test auxiliary tube downward, and is arranged on one side of the shelf. The front plugging assembly is used to plug the front port of the filling cavity, and it also uses the base plate as an assembly base and is located directly in front of the shelf. The rear plugging assembly performs a linear displacement motion under the driving force from the power unit to approach / move away from the test auxiliary tube, thereby realizing / releasing the pressing operation on the rear port of the test auxiliary tube. The air charging unit is connected to the rear plugging assembly and cooperates to fill the filling cavity with high-pressure gas. The first pressure gauge is used to measure the air pressure in the front port area of the filler cavity and is inserted into the front plugging component. The second pressure gauge is used to measure the air supply pressure of the inflation unit.
[0005] As a further improvement of the technical solution disclosed in the present utility model, the front plugging assembly includes a front bearing seat and a front rubber sealing ring. The front bearing seat is detachably fixed to the base plate by means of screws. The front rubber sealing ring is embedded in and fixed on the rear side wall of the front bearing seat. The rear plugging assembly includes a rear bearing seat and a rear rubber sealing ring. The rear bearing seat is suspended directly above the base plate and is directly driven by the power unit. The rear rubber sealing ring is embedded in and fixed on the front side wall of the rear bearing seat. When the test auxiliary tube is placed in place relative to the shelf, the front rubber sealing ring and the rear rubber sealing ring are respectively aligned with the front and rear ports of the filling cavity.
[0006] As a further improvement to the technical solution disclosed in the present invention, the compression unit includes a first supporting base, a horizontal quick-action clamp, a front cylindrical spring, and a pressure column. The first supporting base serves as the mounting base for the horizontal quick-action clamp and is removable for securing to the base plate. The front cylindrical spring serves as a connecting link between the horizontal quick-action clamp and the pressure column. The pressure column, driven by the force from the horizontal quick-action clamp, approaches and compresses the auxiliary test tube. As the process continues, the compression of the front cylindrical spring increases.
[0007] As a further improvement to the technical solution disclosed in this utility model, the inflation unit includes an air source, an electromagnetic shutoff valve, a hose, and a 90° connector. The 90° connector serves as a transition between the rear support and the hose. The electromagnetic shutoff valve controls the on / off flow of air from the air source to the filling chamber.
[0008] As a further improvement to the technical solution disclosed in this utility model, the power unit includes a second supporting base and a push-pull quick-action clamp. The push-pull quick-action clamp serves as the power source for driving the rear-mounted blocking assembly to perform displacement movement. The second supporting base serves as the mounting base for the push-pull quick-action clamp and is detachable for securing it to the baseplate.
[0009] As a further improvement to the disclosed technical solution, the power unit also includes a buffer assembly and a slide block assembly. The buffer assembly serves as a transitional connection between the push-pull quick-release clamp and the rear-mounted plugging assembly, aided by the slide block assembly. The rear-mounted plugging assembly, driven by the push-pull quick-release clamp, approaches and ultimately presses against the rear port of the packing chamber. As the process continues, the buffer assembly accumulates more elastic potential energy.
[0010] As a further improvement of the technical solution disclosed in the present invention, the buffer assembly includes a third bearing base, a horizontal push piece, a left guide column, a right guide column, a left columnar spring and a right columnar spring. The third bearing base uses the slide rail slider assembly as an assembly basis, and is able to perform displacement movement in a direction when subjected to the driving force from the push-pull quick clamp. The horizontal push piece is used as the assembly basis of the rear plugging assembly and is arranged directly in front of the third bearing base. The left guide column and the right guide column both pass through the third bearing base horizontally, and the front ends of both are inserted and fixed to the rear plugging assembly. The left columnar spring and the right columnar spring are respectively and one-to-one mounted on the left guide column and the right guide column. In the process of the rear plugging assembly pressing the test auxiliary tube, the left columnar spring and the right columnar spring are elastically compressed and deformed due to the joint extrusion force from the third bearing base and the horizontal push piece.
[0011] Workers fill the activated carbon particles to be tested into the test auxiliary tube and confirm its filling tightness according to the process standards. At the resistance test station, workers first place the test auxiliary tube in the V-shaped limit groove of the shelf. The power unit is activated, and the rear plugging component gradually approaches the test auxiliary tube. The test auxiliary tube is subjected to the axial pushing force and approaches the front plugging component until the rear plugging component and the front plugging component cooperate to achieve axial pressure on the test auxiliary tube. At the same time, the clamping unit is activated, so that the test auxiliary tube is always under the action of downward pressure. At this point, it is guaranteed that the test auxiliary tube always occupies the correct relative position relative to the shelf throughout the test process, thereby ensuring that the high-pressure gas is smoothly filled into the filling cavity. After the high-pressure gas is completely filled, at time t1, the readings of the first pressure gauge and the second pressure gauge are read respectively, and the difference d1 is calculated. At time t2, the readings of the first pressure gauge and the second pressure gauge are read again respectively, and the difference d2 is calculated. According to the above method, t3, d3...tn, dn are obtained again. Then, the resistance performance curve is fitted with time t as the x-coordinate and d as the y-coordinate.
[0012] In practical applications, the filter material resistance testing tool for activated carbon filters disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:
[0013] 1) Compared with conventional testing methods, the assembly steps of the end cap and adapter are omitted, simplifying the testing steps. This not only effectively shortens the total testing time, but also reduces the labor intensity of workers and relaxes the requirements for their operating skills;
[0014] 2) It is more convenient to operate and the positioning accuracy is easier to ensure. In actual operation, the shelf, rear plugging assembly, front plugging assembly and clamping unit work together to quickly and stably limit the freedom of movement of the test auxiliary tube, ensuring that it always occupies the correct position during the inflation and pressure maintenance process;
[0015] 3) It has good versatility. On the premise that the rear plugging component and the front plugging component remain unchanged, it can be applied to test auxiliary pipes of various diameters at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] In the description of the present invention, it should be understood that the terms "front", "rear", "up", "down", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0033] The following is a detailed description of the present invention in conjunction with specific embodiments. Figure 1 The figure shows a three-dimensional schematic diagram of the filter material resistance test tool for activated carbon filter in the present invention. It can be seen that it mainly consists of a base plate 1, a shelf 2, a pressing unit 3, a front plugging component 4, a rear plugging component 5, a power unit 6, an air charging unit 7, a first pressure gauge 8, a second pressure gauge 9 and a test auxiliary tube 10. The test auxiliary tube 10 is provided with a through-shaped filling cavity for filling the activated carbon particles to be tested (such as Figure 14 In practical applications, the substrate 1 is placed flat on the test bench. The shelf 2 uses the substrate 1 as an assembly base, and a V-shaped limiting groove 21 (as shown in FIG. 2 ) is extended downward from the top wall thereof to match the outer diameter of the test auxiliary tube 10. Figure 2As shown in ). The pressing unit 3 is used to press the test auxiliary tube 10 downward, and is arranged on one side of the shelf 2. The front sealing assembly 4 is used to seal the front port of the test auxiliary tube 10. It also uses the substrate 1 as an assembly basis and is located directly in front of the shelf 2. The rear sealing assembly 5 performs linear displacement under the driving force from the power unit 6 to approach / move away from the test auxiliary tube 10, thereby achieving / releasing the support operation on the rear port of the test auxiliary tube 10. The front sealing assembly 4 includes a front bearing seat 41 and a front rubber sealing ring 42. The front bearing seat 4 is detachably fixed to the substrate 1 by means of screws. The front rubber seal 42 is inlaid and fixed on the rear side wall of the front bearing seat 41. The rear sealing assembly 5 includes a rear bearing seat 51 and a rear rubber sealing ring 52. The rear bearing seat 51 is suspended directly above the substrate 1 and is directly driven by the power unit 6. The rear rubber seal 52 is embedded and fixed on the front side wall of the rear support seat 51. When the test auxiliary tube 10 is placed in place relative to the shelf 2, the front rubber seal 42 and the rear rubber seal 52 are aligned with the front and rear ports of the filling cavity (as shown in Figure 2). Figure 6-9 As shown in FIG. 1 ). The gas filling unit 7 is connected to the rear plugging assembly 5 and cooperates with each other to fill the filler cavity with high-pressure gas. Figure 13 As shown in FIG, the air filling unit 7 includes an air source (not shown), an electromagnetic shut-off valve 71, a hose 72, and a 90° connector 73. The 90° connector 73 serves as a connection transition between the rear support base 51 and the hose 72. The electromagnetic shut-off valve 71 is used to control the on / off process of the air source supplying air to the rear support base 51. Figure 9 As shown in FIG, a rear air passage 511 is provided in the rear bearing seat 51 to communicate the test auxiliary tube cavity and the air source. The first pressure gauge 8 is used to measure the air pressure value in the front port area of the filler cavity, and is inserted into the front plugging component 4. Figure 8 As shown in FIG, a front air passage 411 is provided in the front bearing seat 41 to communicate with the filling chamber and the air pressure gauge 8. The second air pressure gauge 9 is used to measure the air supply pressure of the inflation unit 7. The second air pressure gauge 9 is connected to the hose 72 and is located downstream of the electromagnetic shut-off valve 71 and upstream of the 90° joint 73.
[0034] The worker fills the activated carbon particles to be tested into the test auxiliary tube 10 and confirms the filling tightness according to the process standards. At the resistance test station, the worker first places the test auxiliary tube 10 in the V-shaped limit groove 21 of the shelf 2, the power unit 6 is started, and the rear plugging component 5 gradually approaches the test auxiliary tube 10. The test auxiliary tube 10 is approached by the front plugging component 4 due to the axial pushing force, until the rear plugging component 5 and the front plugging component 4 cooperate to achieve axial pressure on the test auxiliary tube 10. At the same time, the clamping unit 3 is started, so that the test auxiliary tube 10 is always under the action of downward pressure. At this point, it is ensured that the test auxiliary tube 10 always occupies the correct relative position relative to the shelf 2 throughout the test process, thereby ensuring that the high-pressure gas is smoothly filled into the filling cavity. After the high-pressure gas is completely filled, at time t1, the readings of the first barometer 8 and the second barometer 9 are read out respectively, and the difference d1 is calculated. At time t2, the readings of the first barometer 8 and the second barometer 9 are read out again respectively, and the difference d2 is calculated. According to the above method, t3, d3...tn, dn are obtained again. Subsequently, the resistance performance curve of the activated carbon particles is fitted with time t as the x-coordinate and d as the y-coordinate.
[0035] In practical applications, the filter material resistance testing tool for activated carbon filters disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:
[0036] 1) Compared with conventional testing methods, the assembly steps of test auxiliary parts (end covers and adapters, etc.) are omitted, and the test steps are simplified, which not only effectively shortens the total testing time, but also reduces the labor intensity of workers and relaxes the requirements for their operating skills;
[0037] 2) Greater control convenience and easier to ensure positioning accuracy. In actual operation, the shelf 2, rear plugging assembly 5, front plugging assembly 4, and clamping unit 3 work together to quickly and stably restrict the freedom of movement of the test auxiliary tube 10, ensuring that it always occupies the correct position relative to the shelf 2 during inflation and pressure maintenance.
[0038] It should also be noted here that the above-mentioned filter material resistance test tool for activated carbon filters has good versatility and can be used for test auxiliary tubes 10 of various sizes at the same time without the need to modify or replace the rear plugging component 5 and the front plugging component 4.
[0039] like Figure 3As shown in the figure, the clamping unit 3 is mainly composed of several parts, including a first bearing base 31, a horizontal quick clamp 32, a front column spring 33, and a pressure column 34. Among them, the first bearing base 31 serves as the installation base of the horizontal quick clamp 32 and is composed of four support columns 311 that are detachably fixed to the base plate 1. The front column spring 33 serves as a connection and transition between the horizontal quick clamp 32 and the pressure column 34. The pressure column 34 is driven by the driving force from the horizontal quick clamp 32 and approaches and finally compresses the test auxiliary tube 10. As the process continues, the compression of the front column spring 33 increases accordingly. In this way, on the one hand, the downward pressure applied by the pressure column 34 is an elastic force, and the downward pressure can change adaptively with the different stages of the clamping process. Under the premise of ensuring reliable and stable clamping of the test auxiliary tube 10, the outer wall of the test auxiliary tube 10 is effectively avoided from being damaged by the rigid force. On the other hand, when the size of the placed test auxiliary tube 10 changes and the installation height of the horizontal quick clamp 32 needs to be fine-tuned, it is only necessary to remove the support column 311 and replace it with a longer / shorter one. The whole operation process is convenient and quick.
[0040] As a structural preference, Figure 10 As shown in the figure, the power unit 6 includes a second bearing base 61 and a push-pull quick clamp 62. The push-pull quick clamp 62 is used as a power source to drive the rear bearing base 51 to perform displacement movement. The second bearing base 61 is used as the installation base of the push-pull quick clamp 62, and it adopts a detachable manner to achieve fixation with the base plate 1. After the test auxiliary tube 10 is placed in place relative to the V-shaped limit groove 21, the worker manually pulls the push-pull quick clamp 62, and the rear bearing base 51 is able to perform displacement movement toward the test auxiliary tube 10 until the rear rubber seal 52 is reliably supported against the test auxiliary tube 10. The entire operation process is quick and rapid.
[0041] It should be noted here that the above-mentioned horizontal quick clamp 32 and push-pull quick clamp 62 both have a self-locking function, which can prevent the test auxiliary tube 10 from changing its position due to external force or excitation force after clamping, and ensure that the test auxiliary tube 10 always occupies the correct position relative to the shelf 2 during the entire resistance test process.
[0042] Depend on Figure 10 As shown in FIG, it can be clearly seen that the power unit 6 is further provided with a buffer assembly 63 and a slide block assembly 64. The buffer assembly 63 is used as a connection transition between the push-pull quick clamp 62 and the rear plugging assembly 5, and is directed to approach / move away from the test auxiliary tube 10 with the assistance of the slide block assembly 64. Figure 11As shown in FIG, the slide rail and slider assembly 64 is composed of a slide rail 641 and a slider 642. The two parallel slide rails 641 are detachably fixed to the base plate 1, and the two sliders 642 matched therewith are fixed to the buffer assembly 63. Figure 12 As shown in FIG, the buffer assembly 63 primarily consists of a third bearing base 631, a horizontal push member 632, a left guide post 633, a right guide post 634, a left cylindrical spring 635, and a right cylindrical spring 636. The third bearing base 631 is supported by two sliders 642 and removably fixed together. When the push force from the push-pull quick-action clamp 62 is applied, it can perform directional displacement. The horizontal push member 632 serves as the assembly base for the rear bearing base 51 and is located directly in front of the third bearing base 631. The left guide post 633 and the right guide post 634 both extend transversely through the third bearing base 631, and their front ends are inserted and fixed to the rear bearing base 51. The left cylindrical spring 635 and the right cylindrical spring 636 are respectively mounted on the left guide post 633 and the right guide post 634 in a one-to-one correspondence. In the process of the rear blocking component 5 pressing against the test auxiliary tube 10, the left column spring 635 and the right column spring 636 are elastically compressed and deformed (such as Figure 11 、 12 As shown in FIG ), the rear blocking component 5 is pushed by the push-pull quick clamp 62 to approach and abut against the rear port of the test auxiliary tube 10. As the process continues, the elastic potential energy stored in the buffer component 63 increases.
[0043] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
