If a tight stacking form is adopted, the central area of ​​the stacking structure will not be heated smoothly, which will cause the problem of uneven drying and ultimately delay the total drying time; if the honeycomb denitration catalysts are stacked into an overhead structure separated by several partitions, the partitions will form marks on the rigid pressure force of the side walls of each honeycomb denitration catalyst on the stacking structure.

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] As attached Figures 1 to 5 The stacking device before drying of a honeycomb denitration catalyst shown in the figure comprises a displacement device 17, a rotating device 19, a horizontal suction cup bracket 18, a suction cup unit 20 and an asbestos clamp holding manipulator 16; the displacement device 17 can perform XYZ displacement movement, the displacement device 17 is connected to the horizontal suction cup bracket 18 through a device 19 with a vertical axis, the suction cup unit 20 is installed below the horizontal suction cup bracket 18, the asbestos clamp holding manipulator 16 is installed on the horizontal suction cup bracket 18 through a manipulator bracket 21, the asbestos clamp holding manipulator 16 and the suction cup unit 20 are displaced synchronously with the displacement device 17, and are rotated synchronously with the axis of the rotating device 19.

[0023] The suction cup unit 20 includes a plurality of strip-shaped negative pressure shells 31 horizontally arranged in parallel, the negative pressure chambers in the plurality of strip-shaped negative pressure shells 31 are interconnected through a plurality of connecting pipes 25, and also includes a negative pressure suction pipe 26, the suction end of the negative pressure suction pipe 26 is connected to the negative pressure chamber in any one of the strip-shaped negative pressure shells 31, and the other end of the negative pressure suction pipe 26 is connected to a negative pressure pump. When the negative pressure pump is started, negative pressure is formed in the negative pressure chambers in each strip-shaped negative pressure shell 31, and the lower side of each strip-shaped negative pressure shell 31 is a strip-shaped negative pressure suction cup 30, and a plurality of adsorption holes connecting the negative pressure chambers in the strip-shaped negative pressure shells 31 are evenly distributed on the negative pressure suction cup 30, so that each negative pressure suction cup 30 can adsorb a strip-shaped honeycomb denitrification catalyst 13.

[0024] A spring column seat 27 is fixedly installed on the upper side of each strip-shaped negative pressure shell 31. The upper side of each spring column seat 27 is supported and connected to the horizontal suction cup bracket 18 above through a spring buffer support 28, which plays a buffering role to prevent the negative pressure suction cup 30 from rigidly colliding with the adsorbed strip-shaped honeycomb denitrification catalyst 13 when moving downward.

[0025] The asbestos clamping manipulator 16 comprises a pair of cantilevers 22, the roots of which are detachably fixedly connected to the manipulator bracket 21 through a flange 23; a plurality of clamping beams 7 equidistantly distributed and parallel to each other are connected to the lower part of the cantilever 22 through a plurality of lifters 21; clamps are installed at both ends and the lower middle part of each clamping beam 7, and the clamps at both ends and the lower middle part of the clamping beam 7 can clamp the two ends and the middle part of the asbestos strip 11 respectively; therefore, each clamping beam 7 can clamp an asbestos strip 11 below;

[0026] Based on the above structure, the stacking method of the honeycomb denitration catalyst before drying is as follows: Figure 1 As shown;

[0027] S1, with the cooperation of the displacement device 17 and the rotation device 19, the plurality of strip-shaped negative pressure suction cups 30 on the suction cup unit 20 adsorb the plurality of strip-shaped honeycomb denitration catalysts 13 waiting to be dried and neatly arranged, and with the cooperation of the displacement device 17 and the rotation device 19, the suction cup unit 20 transfers the adsorbed plurality of strip-shaped honeycomb denitration catalysts 13 to the stacking area and releases them, thereby forming a first layer 40 of a stacking structure horizontally laid in parallel, wherein the plurality of strip-shaped honeycomb denitration catalysts 13 in the first layer 40 of the stacking structure are equidistantly distributed in parallel, and hot air infiltration gaps are formed between the two adjacent strip-shaped honeycomb denitration catalysts 13;

[0028] S2, each clamping device crossbeam 7 on the asbestos clamping manipulator 16 clamps an asbestos strip 11 below, so that the asbestos clamping manipulator 16 as a whole clamps a plurality of asbestos strips 11 distributed in parallel, and with the cooperation of the displacement device 17 and the rotation device 19, the clamped plurality of asbestos strips 11 are transferred to the top of the first layer 40 of the stacking structure and released, and the released plurality of horizontal asbestos strips 11 are perpendicular to the strip-shaped honeycomb denitration catalysts 13 below;

[0029] S3, with the cooperation of the displacement device 17 and the rotation device 19, the suction cup unit 20 adsorbs the plurality of strip-shaped honeycomb denitration catalysts 13 waiting to be dried, and releases the adsorbed plurality of strip-shaped honeycomb denitration catalysts 13 after transferring them to the top of the first layer 40 of the stacking structure, thereby forming a second layer of the stacking structure laid horizontally in parallel, wherein the plurality of strip-shaped honeycomb denitration catalysts 13 in the second layer of the stacking structure are equidistantly arranged in parallel with each other, and are parallel to the strip-shaped honeycomb denitration catalysts 13 below, and hot air infiltration gaps are formed between the adjacent two strip-shaped honeycomb denitration catalysts 13; an overhead layer 41 supported by a plurality of asbestos strips 11 is formed between the second layer of the stacking structure and the first layer 40 of the stacking structure;

[0030] S4, referring to "S2" and "S3", the third layer and the fourth layer of the stacking structure are completed in sequence, and finally the stacking structure 15 to be dried is formed, and then the stacking structure 15 is sent to the drying furnace for drying; during the drying process, the hot air in the furnace body can smoothly pass through the overhead layer 41 to reach the hot air infiltration gap between any two adjacent strips of honeycomb denitration catalysts 13, so that each strip of honeycomb denitration catalyst 13 of the stacking structure 15 can be heated evenly; at the same time, compared with the rigid partition strips, the asbestos strips themselves are soft and breathable structures, thereby reducing the pressure on the side walls of each honeycomb denitration catalyst 13 on the stacking structure 15, thereby reducing the problem of strangulation marks;

[0031] During the clamping stage of the asbestos strip 11 at "S2", the asbestos strip 11 may not be in a completely regular straight line before being clamped, but may be in a curved shape to a certain extent, such as Figure 5 As shown, the left end 11.1 and the right end 11.2 of the asbestos strip 11 clamped in the middle are too far away from the virtual center line 10, resulting in the problem that the asbestos strip 11 cannot be smoothly clamped in a straight line. For this purpose, the following structure is designed:

[0032] Assume that the length direction of the clamp cross beam 7 is the x direction, and the direction perpendicular to the x direction is the y direction; the two ends of the lower side of the clamp cross beam 7 are respectively provided with a first linear guide rail 8.1 and a third linear guide rail 8.3 extending along the x direction; the middle part of the lower side of the clamp cross beam 7 is provided with a second linear guide rail 8.2 extending along the y direction;

[0033] The first linear guide rail 8.1 and the third linear guide rail 8.3 are respectively provided with a first screw slider 1 and a third screw slider 3 which can be displaced in the x direction, and the second linear guide rail 8.2 is provided with a second screw slider 2 which can be displaced in the y direction;

[0034] The clamps at both ends of the lower side of the clamp beam 7 are respectively denoted as the first clamp 4.1 and the third clamp 4.3, and the clamp in the middle of the lower side of the clamp beam 7 is denoted as the second clamp 4.2;

[0035] The first clamp 4.1, the second clamp 4.2 and the third clamp 4.3 are respectively fixed on the lower sides of the first screw slider 1, the second screw slider 2 and the third screw slider 3;

[0036] The lower sides of the first clamp 4.1, the second clamp 4.2 and the third clamp 4.3 are respectively a first pair of clamping pieces 6.1, a second pair of clamping pieces 6.2 and a third pair of clamping pieces 6.3 capable of clamping action.

[0037] Two first asbestos strip torsion restraining plates 5.1 are arranged between the first clamp 4.1 and the second clamp 4.2 and are spaced apart from each other and are perpendicular to the y direction; two second asbestos strip torsion restraining plates 5.2 are arranged between the second clamp 4.2 and the third clamp 4.3 and are spaced apart from each other and are perpendicular to the y direction.

[0038] When the first screw slider 1 and the third screw slider 3 are away from each other, the distance between the first pair of clamping pieces 6.1 and the third pair of clamping pieces 6.3 is greater than the length of the asbestos strip 11 in a straight state.

[0039] The specific method of clamping an asbestos strip 11 and straightening it by the clamps at both ends and the lower side of the middle of the clamp beam 7:

[0040] A virtual center line 10 is set, and the virtual center line 10 coincides with the symmetry line of the two first asbestos strip torsion restraining plates 5.1 or the symmetry line of the two second asbestos strip torsion restraining plates 5.2;

[0041] Before clamping the asbestos strip 11, the distance between the first pair of clamping pieces 6.1 and the third pair of clamping pieces 6.3 is greater than the length of the asbestos strip 11 in a straight state, and both are in an open state; when the second pair of clamping pieces 6.2 are clamped to clamp the middle of the asbestos strip 11 by displacing the clamping device cross beam 7, since the asbestos strip 11 at this time may not be a regular straight line shape, but a curved shape to a certain extent, the left end 11.1 and the right end 11.2 of the asbestos strip 11 clamped in the middle part deviate too much from the virtual center line 10 along the y direction, causing the left end 11.1 and the right end 11.2 of the asbestos strip to deviate from the clamping interval of the first pair of clamping pieces 6.1 and the third pair of clamping pieces 6.3, even if the first pair of clamping pieces 6.1 and the third pair of clamping pieces 6.3 move closer to each other, they cannot clamp the left end 11.1 and the right end 11.2 of the asbestos strip;

[0042] At this time, the screw drives the second screw slider 2 to move back and forth along the y direction, thereby causing the clamped middle part of the asbestos strip 11 to twist slowly back and forth along the y direction. Under the constraints of the two first asbestos strip twisting constraint plates 5.1 and the two second asbestos strip twisting constraint plates 5.2, the back and forth twisting of the middle part of the asbestos strip 11 along the y direction is immediately transmitted to the left end 11.1 and the right end 11.2 of the asbestos strip, thereby causing the left end 11.1 and the right end 11.2 of the asbestos strip to twist back and forth along the y direction relative to the virtual center line 10. During the process of the left end 11.1 and the right end 11.2 of the asbestos strip twisting slowly back and forth along the y direction, when the left end 11.1 and the right end 11.2 of the asbestos strip are twisted back and forth, the asbestos strip is twisted back and forth along the y direction. 1 and the right end 11.2 of the asbestos strip reach the clamping interval of the first pair of clamping pieces 6.1 and the third pair of clamping pieces 6.3 respectively, the second screw slider 2 is paused; then the first screw slider 1 and the third screw slider 3 are controlled to move closer to each other and then perform a clamping action, so that the first pair of clamping pieces 6.1 and the third pair of clamping pieces 6.3 clamp the left end 11.1 and the right end 11.2 of the asbestos strip respectively; finally, the first screw slider 1 and the third screw slider 3 are controlled to move away from each other, so that the first pair of clamping pieces 6.1 and the third pair of clamping pieces 6.3 in the clamping state are separated from each other, and then the asbestos strip 11 in the bent state is pulled into a straight line that meets the requirements.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
