Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a detachable exhaust gas particulate matter filtration device. Background Technology

[0002] In the emission systems of motor vehicles, industrial boilers, and other equipment, exhaust particulate matter filtration devices are key components for controlling pollutant emissions. They use filter materials to intercept particulate matter (such as PM2.5 and soot) in the exhaust gas, thereby reducing environmental pollution.

[0003] Currently, in common exhaust particulate matter filtration devices, the filter units (such as filter elements) are usually rigidly connected to the exhaust pipes by welding or bolting. When the particulate matter adsorbed by the filter device reaches a certain amount, the disassembly process of cleaning or replacing it is cumbersome and often requires professional tools and a lot of time. This is especially true for large equipment or installation spaces with limited space, where disassembly is even more difficult. In addition, after long-term use, the difficulty in timely cleaning and maintenance not only affects the filtration effect but may also cause the back pressure of the exhaust system to increase due to blockage, affecting the normal operation of the equipment.

[0004] Therefore, there is an urgent need for an exhaust gas particulate matter filtration device that is easy to disassemble and maintain in order to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable exhaust gas particulate matter filtration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detachable exhaust gas particulate matter filter includes an exhaust gas discharge cylinder and an exhaust end pipe. A sealing ring is fixedly sleeved inside the exhaust gas discharge cylinder, and a filter element for filtering exhaust gas particulate matter is slidably sleeved inside the sealing ring. An annular connector is fixedly connected to the bottom of the filter element, and a threaded connecting sleeve is fixedly connected to the bottom side of the annular connector. The threaded connecting sleeve is threadedly connected to the top outer side of the exhaust end pipe. An installation port is provided at the bottom of the exhaust gas discharge cylinder, and the annular connector moves through the installation port.

[0008] Both sides of the annular connector are provided with grooves, and the inner wall of the top side of the groove is provided with a movable groove. A positioning frame is provided in the movable groove. A limit block is fixedly provided on the outer side of the positioning frame. The outer end of the limit block movably extends to the outside of the annular connector and cooperates with the inner wall of the bottom side of the exhaust pipe for limitation. The bottom end of the positioning frame extends into the groove. A horizontally arranged screw is fixedly provided in the groove, and the positioning frame is movably sleeved on the screw. The left end of the positioning frame is rotatably connected to a threaded tube through a bearing. The threaded tube is threadedly connected to the screw. A knob is fixedly connected to the left end of the threaded tube.

[0009] Furthermore, the positioning frame is provided with a through hole, through which the positioning frame is movably sleeved on the screw.

[0010] Furthermore, a guide rod is fixedly installed inside the movable groove, and a guide hole is provided on the positioning frame. The positioning frame is slidably sleeved on the guide rod in the horizontal direction through the guide hole.

[0011] Furthermore, a first spring is fixedly connected between the positioning frame and the inner wall of the movable groove; a second spring sleeved on the screw is fixedly connected between the positioning frame and the inner wall of the groove.

[0012] Furthermore, the side wall of the movable groove is provided with an insertion port, through which the limiting block moves; a limiting ring for limiting the top of the filter element is fixedly sleeved inside the exhaust gas discharge cylinder, and the top circumferential opening of the limiting ring is inclined.

[0013] Furthermore, the outer top of the exhaust pipe is provided with an external thread, and the internal thread on the inner wall of the threaded connection sleeve is connected to the external thread on the outer top of the exhaust pipe by a thread.

[0014] The beneficial effects achieved by this utility model using the above structure are as follows:

[0015] In this invention, by rotating the knob, the threaded tube and the positioning bracket can be moved to the right, thereby moving the limiting block to the right into the movable groove. Then, the annular connector and the filter element can be removed downwards through the installation port via the exhaust pipe for disassembly. This allows the filter element to be quickly removed from the exhaust pipe for cleaning, ensuring the filtration effect.

[0016] Ultimately, in this invention, the filter element inside the exhaust pipe can be quickly removed simply by rotating the knob. This avoids the situation where existing exhaust particulate matter filters are rigidly connected to the exhaust pipe, making it difficult to disassemble, clean, or replace them once a certain amount of particulate matter is filtered. It also avoids the hassle of requiring professional tools for disassembly, greatly reducing the difficulty of disassembly and facilitating timely cleaning and maintenance of the filter element. This significantly ensures the filtration effect and is simple to operate and easy to disassemble and use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A detachable exhaust gas particulate matter filter includes an exhaust gas discharge cylinder 1 and an exhaust end pipe 3. A sealing ring 101 is fixedly sleeved inside the exhaust gas discharge cylinder 1. A filter element 4 for filtering exhaust gas particulate matter is slidably sleeved inside the sealing ring 101. An annular connector 2 is fixedly connected to the bottom of the filter element 4. A threaded connector sleeve 201 is fixedly connected to the bottom side of the annular connector 2. The threaded connector sleeve 201 is threadedly connected to the top outer side of the exhaust end pipe 3. An installation port 103 is provided at the bottom of the exhaust gas discharge cylinder 1, and the annular connector 2 moves through the installation port 103.

[0024] Both sides of the annular connector 2 are provided with grooves 202. The inner wall of the top side of the groove 202 is provided with a movable groove 203. The movable groove 203 is provided with a positioning frame 9. A limiting block 11 is fixedly provided on the outer side of the positioning frame 9. The outer end of the limiting block 11 extends movably through to the outside of the annular connector 2 and cooperates with the inner wall of the bottom side of the exhaust pipe 1 for limiting. The bottom end of the positioning frame 9 extends into the groove 202. A horizontally arranged screw 7 is fixedly provided in the groove 202, and the positioning frame 9 is movably sleeved on the screw 7. The left end of the positioning frame 9 is rotatably connected to a threaded tube 6 through a bearing 14. The threaded tube 6 is threadedly connected to the screw 7. A knob 5 is fixedly connected to the left end of the threaded tube 6.

[0025] In this embodiment, the positioning frame 9 is provided with a through hole 902, and the positioning frame 9 is movably sleeved on the screw 7 through the through hole 902; a guide rod 13 is fixedly provided in the movable groove 203, and the positioning frame 9 is provided with a guide hole 901, and the positioning frame 9 is slidably sleeved on the guide rod 13 in the horizontal direction through the guide hole 901.

[0026] In this embodiment, a first spring 10 is fixedly connected between the positioning frame 9 and the inner wall of the movable groove 203; a second spring 8 sleeved on the screw 7 is fixedly connected between the positioning frame 9 and the inner wall of the groove 202.

[0027] In this embodiment, the side wall of the movable groove 203 is provided with an insertion port 12, and the limiting block 11 is movably inserted through the insertion port 12; a limiting ring 102 for limiting the top of the filter element 4 is fixedly sleeved inside the exhaust gas discharge cylinder 1, and the top circumferential opening of the limiting ring 102 is inclined.
