[0050] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0051] See also Figure 1 The present invention discloses a dust treatment device for a sulfamic acid production system, including a treatment chamber 100, a first filter plate 106, a second filter plate 107, a switching plate 160, a cover plate 200, a maintenance mechanism 300, a replacement mechanism 400, etc.;

[0052] See also Figure 3 The processing chamber 100 is provided with a recovery chamber 101, a first reflux chamber 102, a second reflux chamber 103 and a transition chamber 104 in order in the circumferential direction; the first filter plate 106 is detachably installed between the recovery chamber 101 and the first reflux chamber 102; the second filter plate 107 is detachably installed between the recovery chamber 101 and the second reflux chamber 103; the switching plate 160 is rotatably installed in the processing chamber 100, and is used to connect one of the first reflux chamber 102 and the second reflux chamber 103 to the recovery chamber 101;

[0053] The cover plate 200 is detachably connected to the processing chamber 100, and a through groove 201 corresponding to the first filter plate 106 and the second filter plate 107 is opened on the cover plate 200; the maintenance mechanism 300 is arranged on the cover plate 200, and the maintenance mechanism 300 is located directly above the recovery chamber 101, and is used to clean the first filter plate 106 and the second filter plate 107 ejected from the through groove 201; the replacement mechanism 400 is arranged on the cover plate 200, and the number of the replacement mechanism 400 is two groups, which are used to selectively replace the first filter plate 106 and the second filter plate 107.

[0054] Specifically, driven by the external negative pressure device, the air carrying dust is sucked into the processing chamber 100, and the dust is retained in the recovery chamber 101 after being filtered and intercepted by the first filter plate 106 or the second filter plate 107, and the filtered air flows out from the corresponding first reflow chamber 102 or the second reflow chamber 103, thereby achieving the filtering and separation treatment of the dust carried in the air;

[0055] The switching plate 160 can rotate circumferentially relative to the processing chamber 100, and the rotation range is adapted to the recovery chamber 101 to achieve two different state switching;

[0056] See also Figure 5In one state, the switching plate 160 can be rotated to fit with the second filter plate 107. At this time, the switching plate 160 seals the recovery chamber 101 and the second reflux chamber 103, and the second reflux chamber 103 is connected to the transition chamber 104. The airflow can enter the first reflux chamber 102 from the recovery chamber 101 through the first filter plate 106 (wherein the dotted arrow indicates the flow path of the airflow); in this state, the first filter plate 106 has a filtering effect, while the second filter plate 107 does not work; at this time, the second filter plate 107 can be taken out of the processing chamber 100 for cleaning or replacement without affecting the normal filtering and separation of dust in the air by the first filter plate 106;

[0057] See also Figure 6 In another state, when the filtering effect of the first filter plate 106 is reduced, it needs to be cleaned or replaced, and the switching plate 160 can be rotated to fit with the first filter plate 106. At this time, the switching plate 160 seals the recovery chamber 101 and the first reflux chamber 102, and the first reflux chamber 102 is connected to the transition chamber 104. The airflow can pass through the second filter plate 107 from the recovery chamber 101 to the second reflux chamber 103 (wherein the dotted arrow indicates the flow path of the airflow); in this state, the second filter plate 107 has a filtering effect, while the first filter plate 106 does not work; at this time, the first filter plate 106 can be taken out of the processing chamber 100 for cleaning or replacement without affecting the normal filtering and separation of dust in the air by the second filter plate 107.

[0058] It should be noted that the core of the present invention is that by switching the state of the switching plate 160, the first reflux chamber 102 and the second reflux chamber 103 are selectively connected to the recovery chamber 101, so that the first filter plate 106 and the second filter plate 107 work in turn. When one group of filter plates is working, the other group of filter plates can be cleaned or replaced, which can ensure that the filter plates can be maintained without stopping the machine.

[0059] In one embodiment, see Figure 1 The input end of the recovery chamber 101 of the processing chamber 100 is connected to an air inlet pipe 110, and the bottom of the recovery chamber 101 is connected to a recovery pipe 120; the output end of the first return chamber 102 is connected to a first return air branch pipe 130, and the output end of the second return chamber 103 is connected to a second return air branch pipe 140, and the output ends of the first return air branch pipe 130 and the second return air branch pipe 140 are commonly connected to a return air main pipe 150;

[0060] Specifically, an external negative pressure device (exhaust fan, etc.) is connected to the output end of the return air main pipe 150, and the air inlet pipe 110 is connected to the corresponding part of the aminosulfonic acid production system. Under the action of negative pressure, the dusty air enters the recovery chamber 101 through the air inlet pipe 110, and then enters the first reflux chamber 102 through the first filter plate 106 or enters the second reflux chamber 103 through the second filter plate 107, and finally enters the return air main pipe 150 through the first return air branch pipe 130 or the second return air branch pipe 140, and the dust is retained in the recovery chamber 101 and recovered through the recovery pipe 120;

[0061] For further information, see Figure 3 A mounting frame 105 is provided between the recovery chamber 101 and the first reflux chamber 102 and between the recovery chamber 101 and the second reflux chamber 103. The mounting frame 105 is used to adapt and install the first filter plate 106 or the second filter plate 107. The specific installation method of the first filter plate 106 and the second filter plate 107 is not limited. A slot for accommodating the first filter plate 106 and the second filter plate 107 can be vertically opened on the mounting frame 105. The first filter plate 106 and the second filter plate 107 are vertically inserted into the corresponding mounting frame 105 to complete the rapid installation of the first filter plate 106 and the second filter plate 107. When the first filter plate 106 and the second filter plate 107 need to be cleaned or replaced, the first filter plate 106 and the second filter plate 107 can be vertically pulled out from the corresponding mounting frame 105.

[0062] See also Figure 4 and Figure 5 In order to realize the automatic pop-up of the first filter plate 106 and the second filter plate 107, a lifting spring (not shown in the figure) is arranged at the bottom of the mounting frame 105, and a card slot is opened on the end surface of the mounting frame 105 facing the recovery chamber 101. The first filter plate 106 and the second filter plate 107 are both provided with a wedge block 1051 that is adapted to the card slot and can be elastically retracted, and the switching plate 160 is provided with a push rod 161 that is adapted to the corresponding wedge block 1051;

[0063] In the process of inserting the first filter plate 106 and the second filter plate 107 into the corresponding mounting frame 105, the wedge-shaped surfaces at the lower ends of the wedge-shaped blocks 1051 on the first filter plate 106 and the second filter plate 107 are compressed back into the first filter plate 106 and the second filter plate 107 until the first filter plate 106 and the second filter plate 107 are completely inserted into the corresponding mounting frame 105. At this time, the wedge-shaped blocks 1051 extend out and snap into the corresponding slots under the action of the internal spring, thereby locking the first filter plate 106 and the second filter plate 107, and at the same time driving the jacking spring at the bottom of the mounting frame 105 to be compressed;

[0064] When the first filter plate 106 needs to be cleaned or replaced, the switch plate 160 is rotated to fit the first filter plate 106, and the wedge block 1051 on the first filter plate 106 is pushed out from the corresponding slot by the push rod 161 on the switch plate 160, so that the wedge block 1051 is retracted into the first filter plate 106, thereby unlocking the first filter plate 106. Under the elastic force of the lifting spring, the first filter plate 106 can be ejected from the corresponding through slot 201 along the mounting frame 105;

[0065] Similarly, when the second filter plate 107 needs to be cleaned or replaced, the switching plate 160 is rotated to fit the second filter plate 107, and the wedge block 1051 on the second filter plate 107 is pushed out from the corresponding slot by the push rod 161 on the switching plate 160, so that the wedge block 1051 is retracted into the second filter plate 107, thereby unlocking the second filter plate 107. Under the elastic force of the lifting spring, the second filter plate 107 can be popped out from the corresponding through slot 201 along the mounting frame 105.

[0066] For further information, see Figure 2 and Figure 3 A switching motor 170 for driving the switching plate 160 is installed at the bottom of the processing chamber 100, a first limit block 108 is provided between the transition chamber 104 and the first reflow chamber 102, and a second limit block 109 is provided between the transition chamber 104 and the second reflow chamber 103;

[0067] The state of the switching plate 160 can be switched by driving the switching motor 170 to rotate. The first limit block 108 and the second limit block 109 can limit the rotation range of the switching plate 160 to ensure that the switching plate 160 can be stably switched to a certain state to prevent the switching plate 160 from not rotating in place or rotating in excess.

[0068] Specifically, when the switching plate 160 rotates to fit the second filter plate 107 , the other end of the switching plate 160 just contacts the first limit block 108 ; when the switching plate 160 rotates to fit the first filter plate 106 , the other end of the switching plate 160 just contacts the second limit block 109 .

[0069] In yet another embodiment, see Figure 7 , the two ends of the through slot 201 are symmetrically provided with limiting frames 210, the limiting frames 210 are provided with a receiving cavity adapted to the thickness of the first filter plate 106 and the second filter plate 107, and the side of the limiting frame 210 away from the through slot 201 is provided with an expansion opening 211;

[0070] When the corresponding filter plate pops out from the processing chamber 100, the limit frame 210 can limit the end faces on both sides of the filter plate, thereby ensuring that the filter plate can rise in a vertical posture. When the filter plate rises into place under the action of the lifting spring, the end faces on both sides of the filter plate are respectively fitted with the inner walls on both sides of the limit frame 210, so that the filter plate remains in a vertical state, which is convenient for the maintenance mechanism 300 to remove dust accumulated on the filter plate; in addition, openings are set at the limit frames 210 at both ends, so that the filter plate can move horizontally from the limit frame 210 at any end. When the used filter plate reaches the end of its service life or the filtering effect cannot meet the actual needs, the old filter plate in the limit frame 210 can be pulled out, and then the new filter plate can be horizontally inserted into the limit frame 210 through the replacement mechanism 400, and the expansion opening 211 can facilitate the smooth insertion of the new filter plate into the limit frame 210.

[0071] In further embodiments, see Figure 8 The maintenance mechanism 300 includes a slide rail 310, a first spring 312, a slide plate 320, an oscillating plate 340 and a force storage component. The slide rail 310 is arranged on the cover plate 200 and is located directly above the recovery chamber 101. A guide rod 311 is fixed in the slide rail 310; the slide plate 320 is slidably embedded in the slide rail 310 and movably penetrates the guide rod 311; the first spring 312 is movably sleeved on the guide rod 311 and is located on the side of the slide plate 320 away from the through slot 201; two groups of oscillating plates 340 are provided and correspond to the through slots 201 on both sides. The oscillating plates 340 are fixedly connected to the slide plate 320 through the connecting frame 330, and a plurality of striking heads 341 are distributed in an array on the end surface of the oscillating plate 340 facing the corresponding through slot 201; the force storage component is arranged on the cover plate 200, and is used to pull the slide plate 320 to move toward the end of the slide rail 310 away from the through slot 201 and to disengage from the slide plate 320;

[0072] Specifically, when the first filter plate 106 or the second filter plate 107 pops out from the corresponding through slot 201 and is stuck in the limit frame 210, the slide plate 320 is pulled by the force storage component to move toward the end of the slide rail 310 away from the through slot 201, driving the first spring 312 to compress, and then the force storage component is disengaged from the slide plate 320. The slide plate 320 moves toward the end of the slide rail 310 close to the through slot 201 under the elastic force of the first spring 312, thereby driving the corresponding oscillation plate 340 to approach the first filter plate 106 or the second filter plate 107, and the filter element of the first filter plate 106 or the second filter plate 107 is knocked by the knocking head 341 on the oscillation plate 340, and so on and so forth, and the surface of the filter element is knocked multiple times by the knocking head 341, so that the dust accumulated on the filter element falls off.

[0073] For further information, see Fig. 9The force storage assembly includes a push-pull cylinder 380 fixedly mounted on the cover plate 200, a clamping sleeve 370 fixedly mounted at the end of the telescopic shaft of the push-pull cylinder 380, a driving plate 360 ​​slidably arranged in the clamping sleeve 370, a flip plate 361 is hingedly connected to one end of the driving plate 360 ​​facing the slide plate 320, and a coil spring is arranged at the hinge between the flip plate 361 and the driving plate 360; a limiting plate for limiting the flip plate 361 is arranged on the side of the driving plate 360 ​​close to the through slot 201;

[0074] In the initial state, due to the effect of the coil spring, the flip plate 361 always rotates to a position where it fits with the limit plate, so that the flip plate 361 and the drive plate 360 ​​are distributed in a straight line. Since the flip plate 361 cannot continue to rotate at this time, the push-pull cylinder 380 is used to pull the drive plate 360, and the slide plate 320 can be pushed to move synchronously through the flip plate 361 to store force for the first spring 312. When the slide plate 320 reaches the specified force storage position, the drive plate 360 ​​slides horizontally relative to the sleeve 370, so that the flip plate 361 and the slide plate 320 are When the sliding plate 320 is released, the driving plate 360 ​​is pushed back by the push-pull cylinder 380. When the flip plate 361 contacts the sliding plate 320, the flip plate 361 can rotate unidirectionally, so that the flip plate 361 and the driving plate 360 ​​form a certain angle, until the flip plate 361 flips from one side of the sliding plate 320 to the other side. When the flip plate 361 bypasses the sliding plate 320, it can flip again under the action of the coil spring to a state in which it is in a straight line with the driving plate 360.

[0075] Furthermore, in order to enable the flip plate 361 to automatically separate from the slide plate 320 after the slide plate 320 reaches the designated power storage position, please refer to Figure 8 A guide plate 350 is provided on one side of the slide rail 310, and a guide groove 351 is provided in the guide plate 350, and the guide groove 351 includes a first straight groove 3511, a transition inclined groove 3512 and a second straight groove 3513 which are sequentially spliced; the first straight groove 3511 is parallel to the second straight groove 3513 and the first straight groove 3511 is located on the side of the guide plate 350 close to the slide rail 310; the driving plate 360 ​​is provided with a latch 362 which is movably embedded in the guide groove 351;

[0076] Specifically, when the push-pull cylinder 380 drives the driving plate 360 ​​to move, the latch 362 moves synchronously in the guide groove 351. When the driving plate 360 ​​pulls the slide plate 320 to the specified force storage position, the latch 362 correspondingly enters the second straight groove 3513 from the first straight groove 3511 through the transition inclined groove 3512, so that the driving plate 360 ​​synchronously moves laterally away from the slide plate 320. When the latch 362 enters the second straight groove 3513, the flip plate 361 just disengages from the slide plate 320, thereby completing the automatic release of the slide plate 320.

[0077] During the resetting process of the driving plate 360 ​​, the latch 362 also reenters the first straight groove 3511 from the second straight groove 3513 through the transition inclined groove 3512 , so that the driving plate 360 ​​is laterally close to the slide plate 320 .

[0078] In yet another embodiment, see Fig.10 The replacement mechanism 400 includes a storage rack 410, a pressure plate 430, a pushing plate 460 and a pushing cylinder 470. The storage rack 410 is arranged on the cover plate 200 and is used to store the replacement filter plate 420. The storage rack 410 is provided with a discharge port 411 on the side facing the corresponding limit rack 210; the pressure plate 430 is slidably arranged in the storage rack 410 and is used to press the replacement filter plate 420. The side of the pressure plate 430 away from the replacement filter plate 420 is provided with a slide bar 440 that movably penetrates the storage rack 410, and the slide bar 440 is movably sleeved with a second spring 450; the pushing cylinder 470 is installed on the storage rack 410; the pushing plate 460 is installed on the telescopic shaft of the pushing cylinder 470, and is used to push the replacement filter plate 420 from the discharge port 411 into the corresponding limit rack 210;

[0079] Specifically, a plurality of replacement filter plates 420 are pre-placed in the storage rack 410, and the pressure plate 430 is pushed by the second spring 450 to press the replacement filter plate 420; when the filter plate in the corresponding limiting rack 210 needs to be replaced, the pushing plate 460 is driven to move by the pushing cylinder 470, so that the replacement filter plate 420 in the storage rack 410 can be pushed out horizontally from the discharge port 411, and then the replacement filter plate 420 enters the limiting rack 210 from the expansion port 211 of the corresponding limiting rack 210. As the replacement filter plate 420 enters the limiting rack 210, the old filter plate in the limiting rack 210 is pushed out from the other end, thereby realizing the replacement of the filter plate. When the replacement filter plate 420 completely enters the limiting rack 210, the replacement filter plate 420 is vertically pressed into the processing bin 100.

[0080] It should be noted that the stroke of the push cylinder 470 can be set according to the stroke of the replacement filter plate 420, that is, when the telescopic shaft of the push cylinder 470 is fully extended, the replacement filter plate 420 just completely enters the limiting frame 210;

[0081] In addition, whether to clean or replace the filter plate can be selected according to actual needs. For example, it can be set according to the usage time of the filter plate. When the filter plate is within the set usage time, only the filter plate is cleaned. When the filter plate reaches the set time, the filter plate is replaced. For example, when the filter plate is cleaned a set number of times, it is replaced.

[0082] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
