DETAILED DESCRIPTION

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

[0033] See also Figures 1 to 6 The utility model provides a technical solution: an exhaust gas treatment device that is easy to replace the filter structure, including a treatment device 1, and also including:

[0034] The gas delivery channel 2 and the air inlet channel 3 connected to the exhaust gas treatment device 1, the gas delivery channel 2 has two branch channels 4, and the outer walls of both sides of the two branch channels 4 are installed with cover plates 5, the two cover plates 5 and the branch channels 4 together form a mounting cavity, the middle parts of the two branch channels 4 are provided with slots that penetrate through, and the slots are plugged with filters 6;

[0035] A switching plate 7 is slidably mounted in the mounting cavity, and two ends of the switching plate 7 are respectively inserted into the two branch channels 4;

[0036] A switching assembly is used to drive the switching plate 7 to slide and adjust, and to close and isolate one of the branch channels 4;

[0037] The locking assembly is used to lock or unlock the filter element 6 inserted into the branch channel 4.

[0038] When the exhaust gas treatment device 1 is in use, the exhaust gas enters the air delivery channel 2 through the air inlet channel 3, and then passes through the filter element 6 for filtering and treatment before entering the exhaust gas treatment device 1 for subsequent treatment;

[0039] Among them, since the gas transmission channel 2 is composed of two sub-channels 4, and under the action of the switching component, the switching plate 7 will always close and isolate one of the sub-channels 4, so the exhaust gas will have two paths when passing through the gas transmission channel 2. When the filter 6 in one of the sub-channels 4 needs to be replaced, the switching component controls the switching plate 7 to move and adjust, so that the sub-channel 4 corresponding to the filter 6 is closed and isolated, and the exhaust gas passes through the sub-channel 4 of the other path. At this time, the filter 6 is unlocked by the locking component, and the filter 6 can be taken out from the slot of the sub-channel 4 for replacement;

[0040] In this way, by switching back and forth between the two sub-channels 4, one of the filter elements 6 can be replaced without affecting the exhaust gas flow through the filter, and the filter elements 6 in the two sub-channels 4 can serve as backup for each other, thereby achieving the purpose of replacing the filter element 6 during the process of non-stopping and exhaust gas treatment, thereby improving work efficiency and reducing the time cost of downtime.

[0041] In one of the more preferred embodiments, an implementation of a switching component is provided, which can be specifically referred to in Figure 1-2 ;

[0042] The switching assembly includes a rotating rod 8 rotatably mounted on the outer wall of one of the cover plates 5, a frame plate is fixed to the outer wall of the switching plate 7 located in the mounting cavity, and a pin slidably mounted in the frame of the frame plate is installed at the end of the rotating rod 8;

[0043] The outer wall of the cover plate 5 is also equipped with a servo motor for driving the rotating rod 8 to reciprocate and rotate.

[0044] When switching, the servo motor drives the rotating rod 8 to rotate and adjust, and the rotating rod 8 drives the switching plate 7 to slide, so that one of the branch channels 4 is closed and the other branch channel 4 is opened. Figure 4 As shown;

[0045] The purpose of providing the pins and the frame plate is to eliminate the relative displacement between the rotating rod 8 and the switching plate 7, so that when the rotating rod 8 rotates, the switching plate 7 can be driven to move by the pin to push the frame plate.

[0046] In one of the more preferred embodiments, an implementation of a locking assembly is provided, which can be specifically referred to in Figure 4-6 ;

[0047] The locking assembly includes a connecting plate 16 fixedly connected between the two branch channels 4, holes are provided on both sides of the outer wall of the connecting plate 16, and sliding rods 17 are slidably installed in both sides of the holes, a wedge 18 is fixed to the end of the sliding rod 17 close to the filter 6, and the outer wall of the wedge 18 is provided with an inclined surface, and a locking groove 19 for the wedge 18 to be inserted is provided on the outer wall of the filter 6 extending into the installation cavity, and an outer plate 22 is fixed to the outer wall of the filter 6 away from the locking groove 19;

[0048] The locking assembly further comprises a driving member for driving the sliding rod 17 to move and inserting or disengaging the wedge bar 18 into the locking groove 19 .

[0049] In the locked state, the driving member drives the sliding rod 17 to move, so that the wedge strip 18 is inserted into the locking groove 19 of the filter element 6. Through the inner squeezing of the locking groove 19 by the wedge strip 18 and the limiting effect of the outer plate 22, the filter element 6 can be locked in the branch channel 4 to prevent it from sliding or being separated due to accidental touch.

[0050] However, when unlocking, the driving member will drive the sliding rod 17 to move, so that the wedge strip 18 is disengaged from the locking groove 19. At this time, the filter element 6 can be removed by pulling it outward, so that it is convenient to disassemble and install.

[0051] In one of the more preferred embodiments, the driving member includes a rotating plate 14 rotatably mounted on the outer wall of the connecting plate 16 through an axle seat, long grooves are provided on the outer walls on both sides of the rotating plate 14, pins slidably mounted in the long grooves are installed on the outer walls of the sliding rods 17 on both sides, and blocks 15 are fixed on the outer walls of both sides of the sliding rod 17 close to the rotating rod 8, and the end of the rotating rod 8 is set in a fork shape, and a fixing pin 9 is fixed at the fork;

[0052] The driving member also includes a lower lever 11, one end of which is provided with a sliding groove 12, into which the fixing pin 9 is inserted, and the other end of the lower lever 11 is set as a round head, and the round head abuts against the side wall of one of the stoppers 15, and a sliding ring 10 is slidably installed on the outer wall of the lower lever 11 close to the fixing pin 9, and a spring 13 is connected between the sliding ring 10 and the annular protrusion on the outer wall of the lower lever 11, and the sliding ring 10 contacts and abuts against the fixing pin 9.

[0053] For details on the drive components, please refer to Figure 3-4 , because when removing and replacing the filter element 6, the switch plate 7 must be controlled to move first so that the corresponding branch channel 4 is closed first, so when the rotating rod 8 rotates and drives the switch plate 7 to move, the fixing pin 9 at the fork of the rotating rod 8 will slide in the sliding groove 12, pressing the sliding ring 10 to compress the spring 13 and causing the lower lever 11 to rotate with the round head as the fulcrum, so that the switch plate 7 can close the branch channel 4 while its corresponding filter element 6 is still in a locked state;

[0054] Until the rotating rod 8 rotates to be in the same straight line with the lower lever 11, the spring 13 is compressed to the maximum extent. When the rotating rod 8 rotates beyond the straight line state, under the elastic force of the spring 13, the lower lever 11 will rotate with the fixed pin 9 as the fulcrum, and the round head end will slide along the top of the rotating plate 14, driving the rotating plate 14 to rotate until it contacts and abuts against another stopper 15. At the same time, the rotation of the rotating plate 14 will drive the sliding rods 17 on both sides to move up and down, unlocking the filter element 6 on one side and locking the filter element on the other side.

[0055] In this way, the swing of the lower lever 11 can make the switching plate 7 complete the switching of the sub-channel 4 first, and at the same time, its corresponding filter element 6 will have a delayed unlocking process, until the switching plate 7 completes the switching of the sub-channel 4, the corresponding filter element 6 will be unlocked, and the filter element 6 in the sub-channel 4 after switching will also be locked, avoiding the premature unlocking of the filter element 6, and finally the unlocked filter element 6 can be pulled out and replaced for standby use. When replacing it again, repeat the above steps.

[0056] In one of the more preferred embodiments, an arc-shaped track is provided on the outer wall of the rotating plate 14 between the two stoppers 15 , and arc-shaped recesses are provided at the connection between the two sides of the arc-shaped track and the stoppers 15 .

[0057] The arc-shaped track can be provided to facilitate the sliding limit of the round head to prevent it from deflecting. At the same time, the arc-shaped depression can also facilitate the lower lever 11 to rotate with the round head as a fulcrum.

[0058] In one of the more preferred embodiments, a sealing strip 21 is fixed to the outer wall of the filter element 6 in the branch channel 4, and a slot for inserting the sealing strip 21 is provided on the outer wall of the branch channel 4 away from the installation cavity, and the outer plate 22 can close the slot.

[0059] See also Figure 5 By adding a sealing strip 21, the filter element 6 can be effectively sealed after being locked to prevent smoke from escaping from the slot, thereby ensuring the sealing degree of the branch channel 4;

[0060] In one of the more preferred embodiments, the inner walls of the branch channel 4 at the switching plate 7 and the filter element 6 are provided with tracks for their installation.

[0061] In one of the more preferred embodiments, the inner wall of the locking groove 19 that contacts the wedge strip 18 is designed to be an inwardly convex arc surface.

[0062] By providing the arc-shaped inner convexity, the contact point between the arc-shaped inner convexity and the wedge strip 18 can be aligned, which is beneficial to improving the stability during locking.

[0063] In one of the more preferred embodiments, sealing members 20 are fixed to both ends of the switching plate 7 .

[0064] The function of the seal 20 is also to keep the sub-channel 4 in a relatively sealed state after the switching plate 7 switches the sub-channel 4, so as to prevent smoke from escaping from the worn gap at that position after long-term use.

[0065] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
