Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter cartridges, in particular to an energy-saving dust removal filter cartridge. Background Art

[0002] As the country continues to increase its efforts in air pollution control, energy-saving, environmentally friendly, high-efficiency, low-resistance and long-life filters are increasingly valued in the flue gas treatment industry. For a long time, most domestic and foreign manufacturers of dust removal technology generally use bag dust removal. Ordinary filter cartridges have the following disadvantages: ordinary filter cartridges have a large inner cavity, and it is difficult to clean the dust at low air pressure, and the gas consumption is high, which wastes the energy of the air compressor; the resistance is large during operation, and the dust is not easy to fall off, resulting in a large amount of gas for cleaning and high pressure. Excessive flushing of the filter cartridge filter material can easily cause damage to the filter cartridge, and the bottom of the filter cartridge is easily broken by the high-pressure airflow, reducing the service life of the filter cartridge. Therefore, an energy-saving dust removal filter cartridge has appeared on the market that can effectively reduce working resistance and extend the service life.

[0003] The existing energy-saving dust filter cartridges are generally improved to address the problem of poor performance of existing dust filter cartridges. For example, an energy-saving dust filter cartridge disclosed in the authorized Chinese patent CN202343029U can achieve the effects of large filtering area, small volume, low working resistance, long service life and easy cleaning through the coordinated use of structures such as flange heads, support cages, filter cloth tubes and guide columns. However, the energy-saving dust filter cartridges in the above-mentioned cited documents are generally installed by bolts. When the energy-saving dust filter cartridges are disassembled and replaced in the later stage, the staff needs to unscrew the bolts one by one. Since the bolts are small in size, they are easy to be lost after being placed aside. In addition, the bolts are easily oxidized and rusted due to long-term exposure to the air, making it difficult to remove the bolts thereon, and it is time-consuming and labor-intensive, which reduces the maintenance efficiency, resulting in the need to improve the disassembly and assembly effect of the existing energy-saving dust filter cartridges.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: an energy-saving dust removal filter cartridge, comprising a connecting pipe 1, a connecting head 2, a supporting cage 3, a filter cloth tube 4, a guide column 5, a limiting ring 6 and a filter cartridge 7, wherein the filter cartridge 7 is placed between the connecting pipe 1 and the inner side of the connecting head 2, the outer side of the limiting ring 6 is fixedly mounted on the inner side of the connecting pipe 1 and is located on one end of the filter cartridge 7, one side of the supporting cage 3 is fixedly connected to the side of the connecting head 2 away from the limiting ring 6, the outer side of the filter cloth tube 4 is fixedly mounted on the inner side of the supporting cage 3, and the guide column 5 is sealed and connected to the edge of the connection between the filter cloth tube 4 and the supporting cage 3 by means of adhesive potting;

[0026] A convenient disassembly and assembly mechanism 800 for limiting and fixing is installed between the outer sides of the connection between the connecting pipe 1 and the connecting head 2;

[0027] Through the mutual cooperation between the connecting head 2, the support cage 3, the filter cloth tube 4, the guide column 5, the limit ring 6, the filter cartridge 7 and the convenient disassembly and assembly mechanism 800 on the connecting pipe 1, a function of quick disassembly and assembly between the connecting pipe 1 and the connecting head 2 can be provided, thereby helping the staff to easily replace the filter cartridge 7, saving a lot of time, and improving the disassembly and assembly efficiency of the staff, thereby effectively improving the disassembly and assembly effect of the existing energy-saving dust removal filter cartridge.

[0028] In this embodiment, the convenient disassembly and assembly mechanism 800 is a structure for quickly disassembling and assembling the connection between the connecting pipe 1 and the connecting head 2 .

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the convenient disassembly and assembly mechanism 800 includes a No. 1 fixing block 801 fixedly connected to the outside of the connecting pipe 1 and a No. 2 fixing block 802 fixedly connected to the outside of the connecting head 2. Two connecting plates 803 with mirror symmetry are fixedly installed on the outside of the No. 1 fixing block 801. A pushing assembly and an auxiliary guiding assembly installed in the pushing assembly are installed on the side of the connecting plate 803 away from the connecting head 2. The auxiliary guiding assembly penetrates and extends into the connecting head 2 and is connected to the connecting head 2. The pushing assembly drives the auxiliary guiding assembly to move in order to connect the connecting pipe 1 and the connecting head 2 more tightly and also facilitate disassembly.

[0030] It should be noted that the pushing assembly includes an installation box 8041, a pulling rod 8042, a pull handle 8043 and a cylindrical clamp 8044; one side of the installation box 8041 is fixedly installed on the side of the connecting plate 803 away from the connecting head 2 by bolts, one end of the pulling rod 8042 passes through the installation box 8041 and extends to one side of the pull handle 8043 and is fixedly connected to the pull handle 8043, and the other end passes through the auxiliary guide assembly and the connecting plate 803 in turn and extends to one side of the cylindrical clamp 8044 and is fixedly connected to the cylindrical clamp 8044;

[0031] The pull handle 8043 is connected to the cylindrical clamp 8044 through the pull rod 8042. The pull handle 8043 drives the pull rod 8042 to move, thereby driving the cylindrical clamp 8044 to move, so as to limit the movement of the second fixing block 802.

[0032] It can be understood that a slot for the cylindrical clamping head 8044 to fit and engage is provided on the side of the second fixing block 802 away from the connecting head 2, so as to allow the cylindrical clamping head 8044 to be more stably connected to the second fixing block 802.

[0033] In addition, the auxiliary guide assembly includes a reset spring 8051, a moving block 8052 and an adjusting block 8053; the reset spring 8051, the moving block 8052 and the adjusting block 8053 are all located on the inner side of the mounting box 8041, the inner side of the reset spring 8051 is sleeved on the outer side of the pulling rod 8042, the moving block 8052 is fixedly connected to the outer side of the pulling rod 8042, and the two adjusting blocks 8053 are respectively fixedly connected on both sides of the moving block 8052, and the two adjusting blocks 8053 are distributed in a mirror-symmetrical manner in order to assist the pulling rod 8042 to move more stably.

[0034] In this embodiment, an adjustment groove for the adjustment block 8053 to slide in is provided on the inner wall of the installation box 8041 in order to improve the stability of the movement of the adjustment block 8053.

[0035] It should also be noted that the natural height of the return spring 8051 is equal to the height of the inner side of the installation box 8041, so that when the moving block 8052 moves, the moving block 8052 can be pushed back to its original position by the elastic potential energy return force of the return spring 8051;

[0036] The outer side of the moving block 8052 fits and slides on the inner side of the installation box 8041 in order to further enhance the stability of the pulling rod 8042 when it is pulled.

[0037] The working principle of the above embodiment is:

[0038] When the filter cartridge 7 needs to be replaced, first pinch the pull handle 8043 with the index finger and thumb of both hands respectively and pull in opposite directions, then drive the pull rod 8042 to move under the pulling force generated by pulling the pull handle 8043. Since the moving block 8052 is fixedly connected to the outside of the pulling rod 8042, and since the adjusting block 8053 on the moving block 8052 is slidably connected to the adjusting groove, when the pulling rod 8042 moves, the cylindrical clamping head 8044 can be stably driven to move and the reset spring 8051 is continuously squeezed. When the cylindrical clamping head 8044 is separated from the clamping groove and the restriction on the second fixed block 802 is released, the filter cartridge 7 can be replaced. The connecting pipe 1 and the connecting head 2 are separated so that the filter cartridge 7 can be replaced. When the energy-saving dust removal filter cartridge is used, the filter cloth tube 4 is a folded filter cloth tube 4 formed by continuous folds of the filter cloth. The folded filter cloth tube 4 can greatly increase the filtration area of ​​the filter cloth tube 4. The support cage 3 is a circular tubular frame structure. The guide column 5 can effectively reduce the airflow resistance, enhance the airflow movement ability and movement intensity, thereby improving the filtering effect and cleaning effect. The guide column 5 is a conical column guide column. The upper end of the guide column 5 is arc-shaped. The guide column 5 is coaxial with the filter cloth tube 4. The airflow passes through the filter cartridge 7 into the device, and such a guide dispersion effect is better.

[0039] Compared with the prior art: the energy-saving dust removal filter cartridge, through the mutual cooperation between the connecting head 2, the support cage 3, the filter cloth tube 4, the guide column 5, the limit ring 6, the filter cartridge 7 and the convenient disassembly and assembly mechanism 800 on the connecting pipe 1, can provide a function of quick disassembly and assembly between the connecting pipe 1 and the connecting head 2, thereby helping the staff to conveniently replace the filter cartridge 7, saving a lot of time, and improving the disassembly and assembly efficiency of the staff, thereby effectively improving the disassembly and assembly effect of the existing energy-saving dust removal filter cartridge, and solving the problem of poor disassembly and assembly effect of the existing energy-saving dust removal filter cartridge.
