[0001] The utility model relates to the technical field of automobile exhaust treatment, in particular to a pull-out DPF structure which can be quickly disassembled and assembled. Background Art

[0002] Automobile exhaust is the waste gas produced when a car is in use. It contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, carbon dioxide, etc.

[0003] When treating exhaust gas, a particulate filter (DPF) is usually used to filter and capture pollutants in the exhaust gas. A large amount of particulate matter is adsorbed by the DPF. The particulate matter adsorbed by the DPF gradually accumulates, and the air flow channel becomes narrower. At this time, it is necessary to dismantle, clean and maintain the DPF or conduct experimental collection of exhaust gas pollutant parameters.

[0004] In the prior art, refer to patent document CN213684272U. The device proposed in the patent document guides the airflow through the DPF and then into the upper space from the side of the DPF inner cylinder, and then enters the mixer assembly. The airflow space behind the DPF is sufficient, and the airflow uniformity and overall back pressure can be guaranteed. However, in the actual application of DPF to treat exhaust gas, although the device can facilitate the treatment of exhaust gas, the disassembly and cleaning operation of the DPF is relatively cumbersome, which increases the workload of the test personnel. For this reason, we provide a pull-out DPF structure that can be quickly disassembled and assembled to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] As described in the background technology, the disassembly and cleaning operations of the DPF in the prior art are rather cumbersome, which increases the workload of the test personnel. For this reason, the present embodiment provides a pull-out DPF structure that can be quickly disassembled and assembled. The device can quickly disassemble and install the DPF, greatly improving the convenience of disassembly, cleaning, maintenance, and test parameter collection of the DPF.

[0025] See also Figure 1 - Figure 4 The present embodiment proposes a pull-out DPF structure that can be quickly disassembled and assembled, including an outer cylinder 1. A disassembly mechanism 2 is arranged inside the outer cylinder 1. The disassembly mechanism 2 includes a DPF body 201 slidably connected to the inner wall of the outer cylinder 1, two clamping rods 202, two connecting rods 203, and a telescopic spring 204 sleeved on the outer surface of the clamping rod 202. The ends of the two clamping rods 202 that are away from each other are slidably connected to the reserved holes on the inner wall of the DPF body 201, and the ends of the two clamping rods 202 that are close to each other are fixedly connected to the connecting rod 203.

[0026] refer to Figures 2 to 4 The arrangement of the clamping rod 202 allows the clamping rod 202 to be clamped and locked with the outer tube 1, and through the arrangement of the connecting rod 203 and the telescopic spring 204, the clamping rod 202 can be easily telescopically moved on the inner wall of the DPF body 201, thereby realizing the rapid installation of the clamping rod 202 and greatly improving the convenience of installation for the test personnel.

[0027] The ends of the two clamping rods 202 that are away from each other are clamped with the reserved holes on the inner wall of the outer cylinder 1, and the tips of the clamping rods 202 are passivated. By providing the clamping rods 202, the DPF body 201 can slide when inserted into the outer cylinder 1 due to the squeezing of the inner wall of the outer cylinder 1 by the clamping rods 202. After sliding, the clamping rods 202 enter the reserved holes on the inner wall of the outer cylinder 1 for fixation, thereby realizing the rapid installation of the DPF.

[0028] The inner wall of the outer cylinder 1 is provided with a circular array of slide grooves 2012 , and the outer surface of the DPF body 201 is fixedly connected with a circular array of slide bars 2013 , and the slide bars 2013 are slidably connected to the slide grooves 2012 .

[0029] By providing the slide groove 2012, the DPF body 201 can be stably inserted into the outer cylinder 1, thereby improving the stability of the DPF body 201 in the outer cylinder 1 and avoiding the risk of slight rotation of the DPF body 201 when working in the outer cylinder 1 and affecting its use.

[0030] The outer surfaces of the two connecting rods 203 are hinged with a rotatable connecting frame 205 through a pin shaft, and the outer surface of the connecting frame 205 is fixedly connected to an adjusting frame 206, the inner walls of the two adjusting frames 206 are fixedly connected to a rotating rod 207, the outer surface of the DPF body 201 is fixedly connected to a fixing ring 208, the inner wall of the fixing ring 208 is fixedly connected to two fixing plates 209, and the fixing plates 209 are hinged to the rotating rod 207.

[0031] refer to Figure 4 The setting of the fixing plate 209 can facilitate the limiting guidance and support of the adjustment frame 206, so that by moving the adjustment frame 206, the adjustment frame 206 drives the connecting frame 205 and the connecting rod 203 to extract the clamping rod 202, thereby realizing the locking of the clamping rod 202 and the outer cylinder 1, and then facilitating the rapid disassembly of the DPF, and facilitating the rapid extraction, replacement or maintenance of the DPF.

[0032] The outer surfaces of the two adjustment frames 206 are fixedly connected with first handles 2010 , and the front surface of the fixing ring 208 is fixedly connected with two second handles 2011 .

[0033] By providing the first handle 2010 and the second handle 2011, the first handle 2010 can be moved to drive the clamping rod 202 to move through the transmission of the components, thereby releasing the lock between the clamping rod 202 and the outer cylinder 1, so that the DPF can be pulled out for maintenance and cleaning or installation and disassembly by pulling the second handle 2011 while moving the first handle 2010.

[0034] The outer surface of the fixing ring 208 is sleeved with a clamp 3, and the outer surface of the clamp 3 is provided with two connecting blocks 4 that can clamp the clamp 3. By providing the clamp 3, the overall device and the connecting component can be easily connected and installed, and the connecting blocks 4 can greatly improve the stability after assembly.

[0035] The reserved holes on the upper surfaces of the two connecting blocks 4 are slidably connected with bolts 5, and the threaded lines at the lower ends of the bolts 5 are threadedly connected with nuts. By providing the bolts 5, the clamping work of the clamp 3 can be better facilitated, so that the overall device can be connected with the connecting components, greatly improving the convenience and stability of the device installation.

[0036] The output port of the outer tube 1 is fixedly connected to a discharge tube 6, and the outer surface of the discharge tube 6 is fixedly connected to a connecting ring 7. By setting the discharge tube 6, it can be better connected with subsequent exhaust gas discharge components, and is tightly connected through the connecting ring 7, which can greatly improve the exhaust gas discharge work.

[0037] The annular groove sleeve on the right side of the discharge tube 6 is provided with a sealing ring 8 with a sealing function, and the sealing ring 8 is located inside the connecting ring 7. By providing the sealing ring 8, the sealing performance after connection can be further improved, and the exhaust gas leakage can be prevented from polluting the air, thereby greatly improving the sealing performance and usability of the overall device.

[0038] Working principle: When disassembling and replacing the DPF and collecting test parameters, first, the test personnel manually moves the first handle 2010, and the first handle 2010 drives the adjustment frame 206 to swing under the limiting action of the fixed plate 209 and the rotating rod 207, and then drives the connecting rod 203 and the clamping rod 202 to disengage from the limiting lock of the outer cylinder 1 through the connecting frame 205, so that the DPF can be pulled out from the outer cylinder 1 for inspection or replacement, and when installing, by inserting the DPF into the outer cylinder 1, the clamping rod 202 is squeezed by the limiting squeeze of the outer cylinder 1, so that the clamping rod 202 is contracted by the telescopic spring 204, and when it moves to the reserved hole in the outer cylinder 1, the clamping rod 202 can be inserted into the reserved hole on the inner wall of the outer cylinder 1 through the telescopic spring 204 to be locked, so that the DPF can be quickly installed and disassembled, which greatly improves the practicality and reduces the tediousness of the test personnel in disassembling and installing the DPF.
