Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, in particular to a tentering machine waste gas treatment equipment. BACKGROUND

[0002] The tentering machine is one of the core equipment in the textile dyeing and finishing industry, mainly used for heat setting, width control (door width adjustment), drying and functional finishing of fabrics, and is the key process equipment for giving the fabric final dimensional stability and functionality. During the heat setting of the fabric, it is conveyed into a high-temperature oven, and the fabric is heated to a high temperature of 150-220 DEG C after entering the oven to complete the processes of setting, shrinkage control, door width adjustment, etc. During the heating process, the organic compounds such as dyeing auxiliaries (such as softeners, water repellents, antistatic agents), resin finishing agents (containing formaldehyde) remaining on the surface of the fabric will volatilize and produce a certain amount of waste gas.

[0003] For example, the patent with publication number CN110732219B and publication date of August 25, 2020 discloses an activated carbon adsorption device for organic waste gas purification, relating to the technical field of waste gas purification, which comprises a waste gas treatment box, the left and right ends of the waste gas treatment box are respectively provided with an air inlet and an air outlet, and the inside of the waste gas treatment box is sequentially provided with an installation side plate, a spraying box and a purification box from left to right. The installation side plate is vertically arranged, and a plurality of circular holes are uniformly formed in the side wall thereof. A fan is fixedly installed in each circular hole. An outer filter cylinder is arranged on the outside of the installation side plate. An inner filter cylinder is sleeved in the outer filter cylinder.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] As Figures 1-8 The present application provides a kind of tentering machine exhaust treatment equipment, including processing box 1, multiple groups of adsorption hole box 2 are vertically arranged in processing box 1, the inside of adsorption hole box 2 is filled with activated carbon, further including adjusting mechanism 3, adjusting mechanism 3 is used to take out multiple groups of adsorption hole box 2 from processing box 1 from below to above in turn.

[0031] Specifically, processing box 1 is the hollow rectangular box type structure in the inside, and bottom is provided with the air inlet 11 of waste gas input, top is provided with the air outlet of the gas after processing, as Figure 3As shown, the plurality of adsorption hole boxes 2 are all hollow structures, activated carbon is filled in the internal cavities of the adsorption hole boxes 2, and holes are formed in the top and bottom of the adsorption hole boxes 2, the holes on adjacent adsorption hole boxes 2 are connected to each other, the adjusting mechanism 3 includes a first adjusting assembly 31 and a second adjusting assembly 32, the first adjusting assembly 31 is used to take out the lowermost adsorption hole box 2 from the inside of the treatment box 1, and the second adjusting assembly 32 is used to place the adsorption hole box 2 in the inside of the treatment box 1. In actual use, a plurality of adsorption hole boxes 2 are arranged vertically in the inside of the treatment box 1, then the exhaust gas generated by the tentering setting machine enters the inside of the treatment box 1 from the air inlet 11, the exhaust gas rises in the treatment box 1 and enters the inside of the adsorption hole box 2 through the holes, at this time, the activated carbon in the adsorption hole box 2 can be used to adsorb and treat the entering exhaust gas. Since the adsorption hole boxes 2 are provided in multiple groups, the exhaust gas will enter the inside of each adsorption hole box 2 from bottom to top in turn, and the activated carbon in the multiple groups of adsorption hole boxes 2 is used to adsorb and treat the exhaust gas in turn, then the treated exhaust gas is discharged from the gas outlet 12 at the top of the treatment box 1, and the discharged treated exhaust gas can be transported to other treatment devices through a pipeline. After the treatment box 1 is used for a period of time to treat the exhaust gas, the valve inside the air inlet 11 is closed to prohibit the continuous feeding of the exhaust gas, then the staff can take out the lowermost adsorption hole box 2 from the inside of the treatment box 1 through the first adjusting assembly 31, then the plurality of adsorption hole boxes 2 in the inside of the treatment box 1 are lowered in the inside of the treatment box 1, then a new adsorption hole box 2 with unused activated carbon inside is fed into the inside of the treatment box 1 through the second adjusting assembly 32, the adsorption hole box 2 is located at the top of the plurality of adsorption hole boxes 2 in the treatment box 1. Through the arrangement of the first adjusting assembly 31 and the second adjusting assembly 32, the adsorption hole box 2 closest to the air inlet 11 and with the fastest invalidation of the activated carbon inside can be replaced, and at the same time, through the arrangement of the second adjusting assembly 32, the adsorption hole boxes 2 in the inside of the treatment box 1 can be kept at a set number during the treatment of the exhaust gas. Even if the lowermost adsorption hole box 2 is taken out, a new adsorption hole box 2 can be supplemented in the inside of the treatment box 1, so that the invalidation of the activated carbon at the bottom does not affect the subsequent treatment of the exhaust gas.

[0032] More specifically, the inside of the processing box 1 is provided with a first horizontal groove 13, a second horizontal groove 14 and a sliding groove 15, the first horizontal groove 13 and the second horizontal groove 14 are both vertically provided, the sliding groove 15 is vertically provided, the first horizontal groove 13 is below the second horizontal groove 14, the first horizontal groove 13 is communicated with the second horizontal groove 14 through the sliding groove 15, the side of the adsorption hole box 2 is fixedly installed with a sliding block 21, one end of the sliding block 21 extends into the sliding groove 15 and forms a sliding guide cooperation with the sliding groove 15, because the inside wall of the processing box 1 is fixedly installed with a limiting block 16, the adsorption hole box 2 at the lowermost position is lapped on the limiting block 16, at this time, the sliding block 21 at the side of the adsorption hole box 2 is located at the communication position of the sliding groove 15 and the first horizontal groove 13, when the adsorption hole box 2 at the lowermost position needs to be taken out, the first adjusting assembly 31 drives the adsorption hole box 2 at the lowermost position to move horizontally in the first horizontal groove 13, after the adsorption hole box 2 is taken out, the remaining adsorption hole boxes 2 in the processing box 1 slide downward in the sliding groove 15, then the second adjusting assembly 32 transports a new adsorption hole box 2 whose internal activated carbon is not used to the inside of the processing box 1 through the second horizontal groove 14, and the adsorption hole box 2 is at the uppermost position of the multiple adsorption hole boxes 2 in the processing box 1, in turn reciprocating, the replacement of the adsorption hole box 2 at the bottom and the installation of the new adsorption hole box 2 whose internal activated carbon is not used can be continuously realized.

[0033] In an optional embodiment, preferably, the first adjusting assembly 31 comprises a first side plate 311 and a first connecting rod 312, one end of the first connecting rod 312 is fixedly connected to the first side plate 311, the other end extends into the first horizontal groove 13 and forms a sliding guide cooperation with the first horizontal groove 13, the second adjusting assembly comprises a second side plate 321 and a second connecting rod 322, one end of the second connecting rod 322 is fixedly connected to the second side plate 321, the other end extends into the second horizontal groove 14 and forms a sliding guide cooperation with the second horizontal groove 14.

[0034] Specifically, the side of the processing box 1 is provided with two groups of openings, the first side plate 311 and the second side plate 321 correspond to the two openings respectively, the first connecting rod 312 and the second connecting rod 322 are both provided with two groups, the two groups of first connecting rods 312 are symmetrically arranged on the two sides of the first side plate 311, the two groups of second connecting rods 322 are arranged on the two sides of the second side plate 321, a buckle mechanism or the like can also be arranged on the side of the processing box 1, which is used for limiting and fixing the first side plate 311 and the second side plate 321 at the side openings of the processing box 1 during waste gas treatment, and sealing the openings.

[0035] More specifically, the first adjusting assembly 31 further comprises a one-way assembly, which is installed on the first connecting rod 312.

[0036] Specifically, by the one-way assembly, when the slider 21 moves to the communication position of the first horizontal slot 13 and the sliding slot 15, the first connecting rod 312 moves towards the first side plate 311 in the first horizontal slot 13, and under the blockage of the one-way assembly, the first connecting rod 312 can drive the slider 21 to move synchronously. When the first connecting rod 312 moves away from the first side plate 311 in the first horizontal slot 13, the one-way assembly can smoothly retract into the first connecting rod 312 when contacting the slider 21, so that the movement of the first connecting rod 312 can smoothly pass the slider 21.

[0037] More specifically, the one-way assembly includes a one-way wedge 313, the inside of the first connecting rod 312 is provided with a receiving groove, one end of the one-way wedge 313 extends into the receiving groove (not shown), the other end extends out of the receiving groove, and the inside of the receiving groove is further provided with a spring (not shown), both ends of the spring are connected to the one-way wedge 313, and the inclined surface of the one-way wedge 313 is located on the side away from the first side plate 311. In actual use, when the first connecting rod 312 moves towards the first side plate 311 in the first horizontal slot 13, the vertical surface of the one-way wedge 313 contacts the slider 21, the movement of the first connecting rod 312 drives the movement of the one-way wedge 313, which in turn drives the synchronous movement of the slider 21 in the first horizontal slot 13 and the synchronous horizontal movement of the lowermost adsorption hole box 2 in the processing box 1. When the first connecting rod 312 moves away from the first side plate 311 in the first horizontal slot 13, the movement of the first connecting rod 312 causes the inclined surface of the one-way wedge 313 to contact the slider 21, and under the blockage of the slider 21, the one-way wedge 313 is forced to retract into the receiving groove, and the spring starts to contract. When the first connecting rod 312 completely enters the inside of the first horizontal slot 13, the one-way wedge 313 passes the slider 21 at the communication position of the first horizontal slot 13 and the sliding slot 15, at this time the guide wedge loses the resistance of the slider 21, the spring starts to reset, and drives the one-way wedge 313 to extend out of the receiving groove again.

[0038] In another embodiment of the application, the inside of the second connecting rod 322 is provided with a stop block 323, which is driven by the second connecting rod 322 to move horizontally.

[0039] Specifically, the opposite side surfaces of the two groups of second connecting rods 322 are provided with limiting grooves 324, and the stop blocks 323 are located in the limiting grooves 324. When the second adjusting assembly 32 is extended from the inside of the treatment box 1, and the new activated carbon-unused adsorption hole box 2 is installed between the two groups of second connecting rods 322, the two groups of sliding blocks 21 on the two sides of the adsorption hole box 2 can be respectively placed in the two groups of limiting grooves 324, and the sliding blocks 21 are supported by the stop blocks 323 in the limiting grooves 324, so that when the second connecting rods 322 slide in the second transverse grooves 14, the second connecting rods 322 can stably drive the adsorption hole box 2 to move horizontally in the treatment box, and the adsorption hole box 2 is moved to the uppermost position of the plurality of adsorption hole boxes 2 in the treatment box 1. When the second connecting rods 322 are completely moved into the second transverse grooves 14, the limiting grooves 324 are moved to the communication position of the second transverse grooves 14 and the sliding grooves 15, that is, the limiting grooves 324 are in communication with the sliding grooves 15 at this time.

[0040] More specifically, since the stop blocks 323 need to support the sliding blocks 21 on the two sides of the adsorption hole box 2 during the movement of the second connecting rods 322, the stop blocks 323 are located directly below the sliding blocks 21, and the sliding blocks 21 are placed on the upper surfaces of the stop blocks 323. Since the adsorption hole box 2 needs to be vertically lowered in the sliding grooves 15, the stop blocks 323 also block the lowering of the sliding blocks 21, that is, the adsorption hole box 2. Therefore, in the embodiment, an adjusting part is installed in the second connecting rod 322, which drives the stop block 323 to move out of the limiting groove 324 when the second connecting rod 322 is completely moved into the second transverse groove 14. The adjusting part includes a first rack 326, a second rack 327 and a gear 328. The inside of the second connecting rod 322 is also provided with a giving groove 325, and the first rack 326, the second rack 327 and the gear 328 are located in the giving groove 325. One end of the first rack 326 is fixedly connected to the stop block 323, and one end of the second rack 327 extends from the end of the second connecting rod 322 away from the second side plate 321. As shown in FIG. 6, the first rack 326 and the second rack 327 are engaged with the gear 328, and the first rack 326 and the second rack 327 are symmetrically distributed along the gear 328. Figure 6

[0041] ​In the initial state, i.e. before the second connecting rod 322 is fully inserted into the second horizontal slot 14, one end of the second rack 327 protrudes from the end of the second connecting rod 322, and one end of the block 323 is inserted into the limiting slot 324. During the movement of the second connecting rod 322 in the second horizontal slot 14, the end of the second connecting rod 322 gradually moves to the end of the second horizontal slot 14, i.e. gradually approaches the inner side wall of the processing box 1, until the second rack 327 contacts the inner wall of the processing box 1. With the continuous movement of the second connecting rod 322, the second rack 327 is forced to shrink into the second connecting rod 322 due to the resistance of the inner wall of the processing box, i.e. the second rack 327 moves inside the second connecting rod 322 at this time. The movement of the second rack 327 drives the gear 328 to rotate, and drives the first rack 326 to move away from the second side plate 321, i.e. simultaneously drives the block 323 to move away from the second side plate 321. Through the movement of the block 323, one end of the block 323 moves out of the limiting slot 324. After the block 323 moves out, the block 323 loses the resistance to the sliding block 21, and the sliding block 21 can vertically descend in the limiting slot 324 after losing the resistance of the block 323. After the lowermost adsorption hole plate is extracted, the adsorption hole plate on the second connecting rod 322 can vertically descend in the processing box 1. In addition, as shown in the figure, the yielding slot 325 is provided with the first spring 329, and the first spring 329 gradually shrinks during the movement of the block 323. Figure 6

[0042] When the second adjusting assembly 32 is extracted from the processing box 1, the second connecting rod 322 resets and slides in the second horizontal slot 14, and the second rack 327 gradually escapes from the resistance of the inner wall of the processing box 1. At this time, the first spring 329 starts to reset and pushes the block 323 to reset and move, so that one end of the block 323 is inserted into the limiting slot 324 again for the subsequent installation of the adsorption hole box 2.

[0043] In summary, in the embodiment, the block 323 can not only support the sliding block 21, but also avoid the sliding block 21 when it descends.

[0044] In the above embodiment, because the lowermost adsorption hole box 2 in the processing box 1 is extracted first, and then the remaining adsorption hole boxes 2 descend, that is, multiple adsorption hole boxes 2 quickly descend in the processing box 1 and collide with the limiting block 16, so as to achieve the buffering when the adsorption hole box 2 descends. In an optional embodiment, the bottom of the sliding groove 15 is provided with a second spring 17.

[0045] Specifically, the lower end of the second spring 17 is fixedly connected to the inner wall of the processing box 1. In the embodiment, among the multiple adsorption hole boxes 2, the lowermost adsorption hole box 2 is the first adsorption hole box, and the other adsorption hole boxes 2 are the second adsorption hole boxes.

[0046] ​In the initial state, i.e. before the first adsorption hole box is extracted, the second spring 17 is below the slider 21 on the side of the first adsorption hole box, and the second spring 17 is in a compressed state at this time;

[0047] When the first connecting rod 312 is extracted from the first horizontal slot 13 and drives the first adsorption hole box to move synchronously, since the first connecting rod 312 drives the first adsorption hole box to move horizontally in the processing box 1, when the first adsorption hole box is not completely extracted from the processing box 1, the other second adsorption hole boxes cannot descend due to the resistance of the first adsorption hole box. In addition, during the movement of the first adsorption hole box, the slider 21 on the side of the first adsorption hole box will first move from the position where the first horizontal slot 13 and the sliding slot 15 are connected to the first horizontal slot 13. At this time, the second spring 17 loses the resistance of the slider 21 and starts to reset and stretch. After resetting and stretching, the spring will resist the slider 21 on the side of the second adsorption hole box. That is to say, although the first adsorption hole box has not been completely extracted from the processing box 1, the spring has been reset and resisted under the second adsorption hole box. It can also be understood that the second spring 17 will resist the bottom of the slider 21 on the side of the second adsorption hole box before the second adsorption hole box is lowered. After the first adsorption hole box is completely extracted from the processing box 1, the plurality of second adsorption hole boxes start to descend under the influence of gravity. The slider 21 on the side of the second adsorption hole box slides and descends in the sliding slot 15. Under the support of the elastic force of the spring, the descending speed of the second adsorption hole box can be reduced, and the problem that the descent of the second adsorption hole box causes the collision with the limiting block 16 can be avoided.

[0048] More specifically, the upper surface of the adsorption hole box 2 is provided with a protrusion 22, and the lower surface is provided with a recess 23. The protrusions 22 between adjacent adsorption hole boxes 2 are located in the recesses 23 and form a sliding guide cooperation with the recesses 23. The length direction of the protrusion 22 and the length of the recess 23 are consistent with the length direction of the adsorption hole box 2, that is, consistent with the horizontal movement direction of the adsorption hole box 2. The arrangement of the protrusion 22 and the recess 23 can connect adjacent adsorption hole boxes 2 with each other, so that a plurality of adsorption hole boxes 2 form an integrated structure in the processing box 1, avoiding the relative collision of the adsorption hole boxes 2 during the descent. At the same time, the arrangement of the length direction of the protrusion 22 and the recess 23 can also achieve the horizontal movement of the bottommost adsorption hole box 2 and the installation of the topmost adsorption hole box 2.

[0049] Furthermore, the stop block 323 has a guide inclined surface 3231, and the limiting slot 324 has an L-shaped structure.

[0050] Specifically, in the embodiment, the limiting slot 324 has an L-shaped structure with a narrow upper part and a wide lower part, as shown in Figure 5 and Figure 8 The second spring 17 has a first stroke and a second stroke for buffering the descent of the second adsorption hole box. The second spring 17 is in a contracted state

[0051] In the first stroke, the second spring 17 is stretched after the horizontal movement of the first adsorption hole box, the upper end of the second spring 17 abuts against the bottom of the slider 21 on the side of the second adsorption hole box, after the first adsorption hole box is completely pulled out from the inside of the treatment box 1, the plurality of second adsorption hole boxes begin to descend under the influence of gravity, the second spring 17 begins to contract under the gravity of the plurality of second adsorption hole boxes, in order to avoid the collision between the second adsorption hole box and the limiting block 16 caused by the contraction, the second spring 17 in this stroke is a preliminary contraction, which is to buffer the falling speed of the second adsorption hole box, at this time, the slider 21 on the side of the lowermost second adsorption hole box has not yet moved to the communication between the second transverse groove 14 and the sliding groove 15;

[0052] In the second stroke, after the first adsorption hole box is pulled out from the inside of the treatment box 1, before the new second adsorption hole box 2 with unused activated carbon is installed into the treatment box 1, the second connecting rod 322 needs to be pulled out from the second transverse groove 14, since the block 323 on the second connecting rod 322 has been avoided, and the second adsorption hole box has been preliminarily lowered, the slider 21 on the side of the second adsorption hole box begins to descend from the narrower part of the limiting groove 324 to the faster part, the guide slope 3231 of the block 323 is located on the side of the block 323 close to the second side plate 321, the slider 21 on the side of the uppermost second adsorption hole box after the preliminary descent moves to the side of the block close to the second side plate 321, so during the process of pulling out the second connecting rod 322 from the second transverse groove 14, the guide slope 3231 on the side of the block 323 will contact the slider 21, since the block 323 slides in the avoiding groove 325 after being contacted by the slider 21, and the first spring 329 contracts, until the block 323 contacts the inner wall of the avoiding groove 325, the block 323 cannot continue to move, under the resistance of the wall of the avoiding groove 325, the block 323 and the slider 21 form a wedge-shaped fit, and force the slider 21 to descend again during the movement, that is, the second adsorption hole box descends again, the second spring 17 contracts again, the second adsorption hole box is forced to descend again by the block 323, so that the bottommost second adsorption hole box can move to the designated position smoothly, that is, the slider 21 on the side can move to the communication between the first transverse groove 13 and the sliding groove 15, and since the height of the second connecting rod 322 is consistent with the height of the adsorption hole box 2, the lower surface of the block 323 is flush with the lower surface of the second connecting rod 322, so after the slider 21 descends, it will contact the lower surface of the block 323, with the pulling out of the second connecting rod 322, the slider 21 slides on the lower surface of the block 323, and finally slides to the lower surface of the second connecting rod 322, after the block 323 is out of the resistance of the slider 21, the first spring 329 drives the block 323 to reset and move, so that one end of the block 323 moves again into the limiting groove 324;

[0053] In summary, the first drop of the second adsorption hole box is the drop under the action of its own gravity, which is caused by the compression of the second spring 17. At this time, the second spring 17 serves as a buffer for the second adsorption hole box, avoiding the direct contact of the second adsorption hole box with the limiting block 16 under the influence of gravity and the collision. Therefore, at this time, the second adsorption hole box has not contacted with the limiting block 16, and the contraction of the second spring 17 has not moved the second adsorption hole box to the specified position. Therefore, the secondary drop of the second adsorption hole box is realized by the setting of the baffle, and the second spring 17 is forced to continue to contract under the extrusion force of the stop block 323. That is, the stop block 323 can not only support the sliding block 21 and avoid the sliding block 21 when it is dropped, but also force the second adsorption hole box to drop, so that the second adsorption hole box at the bottom can drop to the specified position.

[0054] The foregoing merely illustrates some exemplary embodiments of the present application, no doubt numerous modifications and alterations can be made by those skilled in the art without departing from the spirit and scope of the present application. Therefore, the above description is in essence illustrative, and should not be construed in the limitation of the present application.
