[0002] In the chemical industry, maintenance personnel often need to work in a confined space when disassembling, inspecting, cleaning and replacing process filter elements. The process filter element is connected to the process filter support layer in the form of a threaded connection, and the filter element head is a circular flange with a reinforced cross brace. Since there are no quick-release tools for replacing filter elements of this type of process filter on the market, maintenance personnel use adjustable wrenches for disassembly and assembly, which is inefficient, and the filter element is poorly tightened after reinstallation, which is easy to cause leakage, resulting in reduced process filtration accuracy.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the utility model, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned above, the utility model provides a filter element quick-release tool for a process filter. By adopting an L-shaped special-shaped wrench mouth, the disassembly process is convenient. The L-shaped block is used to hook the filter element cross brace and pull it out from the filter, so as to solve the problem that the maintenance personnel use an adjustable wrench to disassemble and assemble the filter element inefficiently, and the filter element has a poor fastening effect after reinstallation, which is easy to cause leakage and leads to reduced process filtration accuracy.

[0005] The utility model provides a filter element quick-disassembly tool for a process filter, comprising a main body and a wrench mouth, wherein the main body is a rod; the wrench mouth is installed at the end of the main body, and a through-opening is opened along a radial direction of the main body, and a bayonet is opened on one side parallel to the axial direction of the main body, and the bayonet of the wrench mouth is connected with the through-opening; wherein the wrench mouth passes through a cross brace of the filter element through the bayonet, and cooperates with the through-opening to limit the cross brace.

[0006] In an embodiment of the present invention, the height dimension of the wrench opening in the through-opening direction is the same as the diameter dimension of the main body.

[0007] In one embodiment of the utility model, the wrench opening includes a plate-like block and an L-shaped block, one end of the plate-like block is mounted at the end of the main body; the L-shaped block includes a first side and a second side that are folded and connected, the end of the first side is mounted at the end of the main body, and the end of the second side is spaced from the other end of the plate-like block to form a bayonet.

[0008] In one embodiment of the present invention, the width dimension of the plate-shaped block and the L-shaped block is the height dimension of the wrench opening.

[0009] In an embodiment of the present invention, the length of the plate-shaped block is smaller than the length of the first side of the L-shaped block.

[0010] In an embodiment of the present invention, the spacing dimension between the second side of the bayonet and the plate-shaped block is smaller than the height dimension of the wrench opening.

[0011] In one embodiment of the present invention, a connecting ring is further included. The connecting ring is installed on the other end of the main body away from the wrench opening, and the diameter of the connecting ring is not greater than the diameter of the main body.

[0012] In an embodiment of the present invention, the axial direction of the connecting ring is perpendicular to the axial direction of the main body and the direction in which the through opening is opened.

[0013] In one embodiment of the present invention, a cross bar is further installed in the connecting ring, and the sizes of the cross bar at both ends of the connecting ring are the same or different.

[0014] In one embodiment of the present invention, the crossbar is movably / fixedly installed in the connecting ring.

[0015] The beneficial effects of the utility model include at least the following:

[0016] 1. The utility model provides a filter element quick-disassembly tool for a process filter. By using the steel plate of the plate-shaped block and the L-shaped steel of the L-shaped block as the wrench mouth, when the process filter needs to be cleaned and the filter element replaced, the wrench mouth is obliquely penetrated through the cross brace at the top of the filter element, and the cross brace is stuck in the wrench mouth. The cross bar can be easily rotated to remove or install the filter element.

[0017] 2. The L-shaped wrench opening is used to facilitate the disassembly process. The L-shaped block is used to hook the filter element cross brace and pull it out of the filter, which minimizes the risk of personnel entering the restricted space in the process filter.

[0018] 3. After adopting the quick-release tool, the personnel provide a tightening force to the filter element by rotating the cross bar of the quick-release tool, making the tightening effect more effective. This avoids the situation in the past when the maintenance personnel reinstall the filter element, because there is no reliable force point on the circular head on the top of the filter element, resulting in poor tightening effect. It also prevents the material from escaping without being filtered due to poor thread tightening.

[0019] It should be understood that the above general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. It should also be understood that the terms used in the embodiments of the present invention are intended to describe specific implementations, rather than to limit the scope of protection of the present invention.

[0025] See also Figure 1 to Figure 2 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any structural modification, change in proportional relationship, or adjustment of size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as position and quantitative relationship quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantial changes in the technical content.

[0026] See also Figure 1 and Figure 2The utility model provides a filter element quick-disassembly tool for a process filter, comprising a main body 1 and a wrench mouth 2, wherein the main body 1 is a rod; the wrench mouth 2 is installed at the end of the main body 1, and a through hole 20 is opened along a radial direction of the main body 1, and a bayonet 200 is opened on one side parallel to the axial direction of the main body 1, and the bayonet 200 of the wrench mouth 2 is connected with the through hole 20; wherein the wrench mouth 2 passes through the cross brace 101 of the filter element 100 through the bayonet 200, and cooperates with the through hole 20 to limit the cross brace 101.

[0027] Specifically, in the embodiment of the utility model, round steel or steel pipe can be used as the main body 1 of the quick-release tool, and its length can be set according to the use environment. The wrench mouth 2 at the end of the main body 1 can be fixed by welding. The through-hole 20 and the opening provided on the wrench mouth 2, when the process filter needs to be cleaned and the filter element 100 needs to be replaced, the wrench mouth 2 is passed through the opening obliquely through the cross brace 101 on the top of the filter element 100, and the cross brace 101 is stuck in the through-hole 20 in the wrench mouth 2 and limited, and then the filter element 100 can be easily driven to rotate by rotating the main body 1, and the filter element 100 can be removed or installed.

[0028] In this way, by setting the wrench opening 2, the problem of poor fastening effect caused by the lack of reliable force points on the circular head on the top of the filter element 100 when the maintenance personnel reinstalled the filter element 100 in the past is solved. After using the quick-release tool, the personnel provide a fastening force to the filter element 100 by rotating the cross bar 4, making the fastening effect more effective, thereby avoiding the situation where the material escapes directly without being filtered due to poor thread fastening.

[0029] Furthermore, the height dimension of the wrench mouth 2 in the direction of the through-port 20 is the same as the diameter dimension of the main body 1. In order to facilitate the use of a quick-release tool to disassemble the filter element 100, the wrench mouth 2 is kept consistent with the main body 1 in one direction (i.e., the height dimension in the direction of the through-port 20 is the same as the diameter dimension of the main body 1), which is convenient for storage, and the size of the wrench mouth 2 must be sufficient to fit into the space formed between the end of the filter element 100 and its cross brace 101, so it cannot be too large. At the same time, the through-port 20 in the wrench mouth 2 must maintain the limiting clamping effect of the cross brace 101 at the end of the filter element 100, and it is necessary to avoid the narrow wrench mouth 2 causing the contact surface with the cross brace 101 to be too small, causing stress concentration, and increasing the risk of damaging the cross brace 101 structure. In this way, the size of the wrench mouth 2 can be set to be consistent with the diameter dimension of the main body 1 of the quick-release tool.

[0030] See also Figure 1 and Figure 2In one embodiment, the wrench opening 2 includes a plate-like block 21 and an L-shaped block 22, wherein one end of the plate-like block 21 is mounted at the end of the main body 1; the L-shaped block 22 includes a first side 221 and a second side 222 that are folded and connected, wherein the end of the first side 221 is mounted at the end of the main body 1, and the end of the second side 222 is spaced apart from the other end of the plate-like block 21 to form a bayonet 200.

[0031] Furthermore, the width of the plate block 21 and the L-shaped block 22 is the height of the wrench opening 2. The length of the plate block 21 is less than the length of the first side 221 of the L-shaped block 22. The spacing between the second side 222 of the bayonet 200 and the plate block 21 is less than the height of the wrench opening 2.

[0032] Specifically, the through opening 20 and the buckle of the wrench opening 2 can be formed by combining a plate-like block 21 and an L-shaped block, which can be welded on the left and right sides of the end of the main body 1 respectively to form a steel plate and an L-shaped steel with a width equal to the diameter of the main body 1 as the wrench opening 2, wherein the steel plate and the L-shaped steel are the plate-like block 21 and the L-shaped block 22 respectively. Further, according to the description of the size of the wrench opening 2 in the above embodiment, the size of the first side 221 and the second side 222 of the corresponding plate-like block 21 and the L-shaped block 22 is decomposed and described.

[0033] In this way, the L-shaped special-shaped wrench opening 2 is used to facilitate the disassembly process. The filter element 100 cross brace 101 can be hooked with the L-shaped stopper and then easily pulled out from the filter, thereby reducing the risk of personnel entering the confined space in the process filter.

[0034] It should be noted that the quick release tool in the embodiment of the utility model has a wider application advantage: please refer to the attached Figure 2 As shown, the quick-release tool can be used to replace the filter element 100 of process filters of different forms, especially in the disassembly process of the filter element 100 of the vertical barrel filter. Since the filter element 100 is threadedly connected to the supporting layer inside the filter, the filter element 100 can be sent into the threaded port of the supporting layer inside the filter using the L-shaped tool head of the quick-release tool, and then the cross brace 101 can be rotated clockwise to tighten and fix the filter element 100.

[0035] Similarly, the quick-release tool in the embodiment of the utility model also has the advantage of safety: vertical barrel filters mostly use a flow direction of material entering from the bottom and exiting from the top due to process requirements, so the support layer of the filter element 100 is often located in the middle and lower part of the barrel. After the material is emptied and replaced, there will still be toxic materials remaining in the lower part of the confined space. The L-shaped quick-release tool can avoid the risk of maintenance personnel entering the confined space.

[0036] See also Figure 1 In one embodiment, it further includes a connecting ring 3 , which is mounted on the other end of the main body 1 away from the wrench opening 2 , and the diameter of the connecting ring 3 is not greater than the diameter of the main body 1 .

[0037] Specifically, the upper end of the main body 1, i.e., the end away from the wrench opening 2, can be used to weld a steel pipe not larger than the diameter of the main body 1 as a connecting ring 3, which is convenient for the quick-release tool to be stored in a hanging manner, and can also form a different outer contour with the main body 1, which is convenient for holding and applying force to perform rotation operations. Other tools at the construction site, such as a wrench, a screwdriver, or a crowbar, can also be used, inserted into the connecting ring 3, and used as a force rod for the rotation of the main body 1 in the quick-release tool, further reducing the difficulty of applying force when using the quick-release tool to rotate and install the filter element 100.

[0038] Furthermore, the axial direction of the connecting ring 3 is perpendicular to the axial direction of the main body 1 and the opening direction of the through hole 20. A crossbar 4 is also installed in the connecting ring 3, and the sizes of the crossbar 4 at both ends of the connecting ring 3 are the same or different. The crossbar 4 is movably / fixedly installed in the connecting ring 3.

[0039] Specifically, bolts or round steel are passed through the connecting ring 3 to serve as the load-bearing crossbar 4, and the two sides of the crossbar 4 can be fixed by bolts or welding to the connecting ring 3. By limiting the angle relationship between the connecting ring 3 and the through hole 20 on the main body 1 and the wrench opening 2, it is ensured that the installed crossbar 4, the main body 1 and the wrench opening 2 are located on the same plane, which is convenient for use and storage.

[0040] Furthermore, by selecting the fixed relationship between the cross bar 4 and the connecting ring 3, the cross bar 4 and the connecting ring 3 can be adjusted to change the length of the two ends of the cross bar 4 exposed from the two ends of the connecting ring 3. In this way, by adopting an adjustable connection form between the cross bar 4 and the vertical rod, which mainly adjusts the bolt limit at both ends of the cross bar 4 (the bolts are shown in the drawings but not marked), the cross bar 4 can be changed from a T-shape to an inverted L-shape according to the operating space, thereby strengthening the force acting on the rotation of the filter element 100 and increasing the reliability of the loosening and tightening of the filter element 100.

[0041] In summary, the utility model provides a quick-release tool for a filter element 100 for a process filter. By adopting an L-shaped special-shaped wrench mouth 2, it is convenient to use the L-shaped block 22 to hook the filter element 100 cross support 101 during the disassembly process and pull it out from the filter, thereby greatly reducing the risk of personnel entering the confined space in the process filter; and the personnel provide a tightening force to the filter element 100 by rotating the cross bar 4 of the quick-release tool, making the tightening effect more effective, avoiding the situation in the past when the maintenance personnel reinstalled the filter element 100, due to the lack of a reliable force point on the circular head on the top of the filter element 100, thereby preventing the material from escaping without being filtered due to poor thread tightening.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
