DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0034] Combine Figure 1-Figure 3A bag filter with high sealing performance includes a filter body 1 and a cover 2 arranged on the top of the filter body 1, and also includes a bag body 3 arranged inside the filter body 1. The interior of the filter body 1 is slidably connected to a sliding frame 11, and a limiting hole 12 is also provided on the top of the filter body 1. A sealing gas cylinder 13 is also fixedly connected to the interior of the filter body 1, and the bottom of the cover 2 is fixedly connected to a limiting rod 121 and a mounting block 21. A mounting groove 211 is also provided on the top of the filter body 1. A convenient disassembly mechanism is provided inside the filter body 1, which can facilitate the staff to remove the cover 2 from the filter body 1.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example 1:

[0037] In order to solve the problem that the sealing performance of bag filters is generally poor, a special sealing structure is often required for sealing in the process of wastewater filtration. However, the existing sealing structure is relatively complex, which increases the cost of using the filter. This embodiment discloses the following technical solutions, specifically Figures 1-4 As shown, there are four groups of limiting holes 12 and limiting rods 121, and the limiting holes 12 match the limiting rods 121, and there are two groups of mounting blocks 21 and mounting grooves 211, and the mounting blocks 21 match the mounting grooves 211. The interior of the sealing gas cylinder 13 is slidably connected with contact rods 131, and the contact rods 131 are provided with two groups, one group of contact rods 131 is fixedly connected to the sliding frame 11, and one end of the contact rods 131 of the other group extends to the outside of the filter body 1, and the bottom of the top cover 2 is also fixedly connected to a fixing frame 132, and the fixing frame 132 and the sliding frame 11 are provided with teeth, the top of the cloth bag body 3 is fixedly connected to an extension cloth 31, and the extension cloth 31 matches the fixing frame 132 and the sliding frame 11. When using the device, the top cover 2 can be installed on the top of the filter body 1 Due to the gravity factor, the top cover 2 can be installed on the top of the filter body 1 through the limiting effect of the limiting rod 121 and the limiting hole 12. At this time, the top cover 2 can cause one group of contact rods 131 to descend, and the descending of one group of contact rods 131 causes the air inside the sealing cylinder 13 to be compressed, thereby causing the other group of contact rods 131 to move out of the sealing cylinder 13. At this time, the sliding frame 11 moves, and the sliding frame 11 and the fixing frame 132 at the bottom of the top cover 2 can clamp the extended cloth 31 on the top of the bag body 3, and the setting of the teeth on the fixing frame 132 and the sliding frame 11 thereby improves the sealing of the extended cloth 31, thereby achieving a sealing effect, realizing the effect of improving the sealing performance of the device through a simple structure, and facilitating use.

[0038] At the same time, in order to solve the problem that the shells of existing bag filters are mostly installed by screws or welding, and thus tools need to be used every time the bag is replaced, which affects the efficiency of bag replacement, the present embodiment also discloses the following solution: the disassembly mechanism includes a magnetic block 22 fixedly connected to the bottom of the mounting block 21, and an electromagnet 221 fixedly connected to the inside of the mounting groove 211, and the electromagnet 221 is electrically connected to the external power supply of the filter body 1, and the left and right sides of the cover top 2 are provided with a grabbing groove 222. During the installation process, the mounting block 22 at the bottom of the cover top 2 can be fixedly connected to the bottom of the cover top 2. The mounting block 21 is aligned with the mounting groove 211 and then put into the mounting groove. At this time, the magnetic block 22 is in contact with the electromagnet 221. When the device starts working under the power-on condition, the electromagnet 221 is energized so that the mounting block 21 can be firmly fixed inside the mounting groove 211. When disassembly is required, the device is powered off and the electromagnet 221 is de-energized. At this time, the staff can remove the cover top 2 from the top of the filter body 1 through the grabbing groove 222, and then the bag body 3 can be replaced, thereby realizing the function of opening the filter body 1 without the need for fixing it with bolts and nuts, thereby improving work efficiency.

[0039] Example 2:

[0040] In this embodiment, another disassembly method is disclosed, which is different from the first embodiment and can make it more convenient for the user to replace the bag body 3. For details, please refer to Figure 5 The disassembly mechanism includes a fixing port 23 provided on the mounting block 21, and also includes a transmission spring 231 fixedly connected to the inside of the limiting hole 12, and one end of the transmission spring 231 is fixedly connected to the ejection rod 232, and one side of the filter body 1 is slidably connected to a pressing block 233, and one end of the pressing block 233 is fixedly connected to a spring rod 234 and a trapezoidal block 235, and the other end of the spring rod 234 is fixedly connected to the inside of the filter body 1, and the trapezoidal block 235 matches the fixing port 23. When the cover top 2 needs to be removed from the filter body 1, the filter can be pulled The pressing blocks 233 on the left and right sides of the main body 1 drive the trapezoidal clamping block 235 to move out from the inside of the fixing port 23. At this time, under the action of the transmission spring 231, the ejection rod 232 lifts the cover top 2, and the filter body 1 can be opened. When the cover top 2 needs to be installed, the cover top 2 is placed on the top of the filter body 1 and the cover top 2 is pressed downward. At this time, the trapezoidal clamping block 235 automatically enters the inside of the fixing port 23 under the action of the spring rod 234 and fixes the cover top 2, so that the cover top 2 can be opened and closed without using any electrical equipment.

[0041] Example 3:

[0042] In this embodiment, another disassembly method is disclosed, which is different from the first and second embodiments and can make it more convenient for the user to replace the bag body 3. For details, please refer to Figure 6 The disassembly mechanism includes an electric push rod 24 fixedly connected to the inside of the filter body 1, and the output end of the electric push rod 24 is fixedly connected to a pushing block 241, and the pushing block 241 matches the mounting block 21. When the filter body 1 needs to be opened, the electric push rod 24 can be started at this time, and the electric push rod 24 drives the pushing block 241 to move, thereby moving the mounting block 21 out of the inside of the mounting groove 211. At this time, the cover top 2 can be removed from the filter body 1. The setting of the electric push rod 24 can greatly facilitate the user's operation of opening the filter body 1.
