Description

Technical Field

[0001] The utility model belongs to the field of filters, in particular to a filter cartridge air leakage prevention device. Background Art

[0002] The filter cartridge is a surface filter element. It uses the tiny air-permeable tissue formed on the surface of the filter material to block the particulate matter in the gas. In the industrial field, filter cartridges are usually selected for filtration. However, there are some difficult to solve problems during the use of filter cartridges: Due to the small size and compact structure of the filter cartridge dust collector, the filter cartridge of the important filter cartridge dust collector is prone to air leakage. If the seals at both ends are not tight enough, it may even cause the filter cartridge to reduce its efficiency during operation. In serious cases, smoke will occur, thereby damaging other components. Utility Model Content

[0003] In view of the above, the utility model provides a filter cartridge air leakage prevention device to solve the problems raised in the above background technology.

[0013] The utility model is further described below in conjunction with the accompanying drawings and some implementation methods.

[0014] exist Figure 1-Figure 2In the invention, a filter cartridge air leakage prevention device is provided, comprising a device body 1, wherein the device body 1 comprises two fixing components 2 for fixing the edge of the filter cartridge, a support plate 3 for supporting the fixing components 2, and a smoke detector 303 for detecting smoke and dust and giving a warning, wherein the two fixing components 2 are respectively fixed at both ends of the support plate 3, and the fixing components 2 are respectively located at both ends of the outside of the filter cartridge, and comprise a wind force sensor 201 for detecting wind force to judge the air leakage of the filter cartridge, a fixing ring 202 fixed at the gap at the edge of the filter cartridge to prevent air leakage, and an adjusting device is arranged at the connection of the fixing ring 202. The nut 204 of the same diameter as the fixing ring 202 is provided. The connection of the fixing ring 202 is initially in an unconnected state. By gradually tightening the nut 204 on the stud, the fixing ring 202 is gradually buckled together, so that the diameter of the fixing ring 202 becomes smaller and smaller. A wrench 205 for tightening the nut 204 is fixedly provided on the outside of the nut 204. The two ends of the support plate 3 are provided with a slide rail 301 for rotating the wrench 205 to tighten the nut 204, and a motor 302 for driving the wrench 205 to move on the slide rail 301. The wind sensor 201 The output end is connected to the input end of the motor 302, and the output end of the motor 302 is connected to the input end of the wrench 205. The motor 302 is connected to the wrench 205 and the slide rail 301 respectively. The slide rail 301 is in a circle shape. When the motor 302 drives the wrench 205 to rotate on the slide rail 301, the nut 204 is gradually tightened. When the nut 204 is screwed to the bottom of the stud, the motor 302 no longer drives the wrench 205 to rotate. When the wind force sensor 201 detects air leakage at both ends of the filter cartridge, the motor 302 drives the wrench 205 to slide on the slide rail 301 to tighten. Tighten the nut 204 to reduce the diameter of the fixing ring 202 and fit it closely to the edge gap of the filter cartridge to prevent air leakage. When the nut 204 is tightened to the bottom of the stud to minimize the diameter of the fixing ring 202, if the filter cartridge still leaks air and dust fills the entire space, the smoke detector 303 detects the smoke and issues an alarm and sends a reminder to the mobile terminal. When in use, if air leaks from both ends of the filter cartridge, the motor 302 drives the wrench 205 to rotate on the slide rail 301 to tighten the nut 204 to prevent air leakage from the filter cartridge, and if smoke and dust fill the filter cartridge, the smoke detector 303 issues a reminder.

[0015] In this embodiment, a rubber ring 203 for preventing air leakage is arranged inside the fixing ring 202. The rubber ring 203 can effectively isolate smoke and dust in the filter cartridge and prevent the filter cartridge from leaking.

[0016] In this embodiment, the smoke detector 303 is fixed on the support plate 3 and can monitor the smoke environment around the filter cartridge in real time.

[0017] In this embodiment, the smoke detector 303 is connected to a mobile terminal, and the smoke and dust situation around the filter cartridge can be viewed in real time through a mobile terminal such as a mobile phone or a computer.

[0018] In this embodiment, the wind sensor 201 is fixed on the inner side of the rubber ring 203. A groove is provided on the inner side of the rubber ring 203 where the wind sensor 201 is stored to prevent the wind sensor 201 from being damaged when the diameter of the fixing ring 202 becomes smaller. The wind sensor 201 detects air leakage at the edge gap of the filter cartridge in real time.

[0019] In this embodiment, the wind sensor 201 is a common ventilation resistance testing device, such as a CZC5 portable ventilation resistance measuring instrument.

[0020] In this embodiment, the motor 302 is a common rotating motor device, such as a GB / T4831-2016 model, a Y160M-4 model rotating motor, etc.

[0021] In this embodiment, the smoke detector 303 is a common smoke detection device, such as a JT-LZ-1902 model, a JTY-GF-XY701 model smoke detector, and the like.

[0022] In this embodiment, the control circuit of the utility model is a common circuit in the circuit field. The device of the utility model can be connected to an external power supply or a built-in battery through a power cord to provide power for the device. Technicians in the relevant technical field can implement it and will not be elaborated here.

[0023] During the specific implementation of the utility model: during use, when the wind sensor 201 detects air leakage at both ends of the filter cartridge, the motor 302 drives the wrench 205 to slide on the slide rail 301 to tighten the nut 204, so that the diameter of the fixing ring 202 becomes smaller and fits tightly against the edge gap of the filter cartridge to prevent air leakage from the filter cartridge; when the nut 204 is tightened to the bottom of the stud to make the diameter of the fixing ring 202 the smallest, and the filter cartridge still leaks air and dust fills the entire space, the smoke detector 303 detects the smoke and sounds an alarm and sends a reminder to the mobile terminal.
