DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The denitration catalyst sample preparation device provides two technical solutions:

[0025] Such as Figures 1-4The first embodiment is shown: It includes a workbench 1. A gantry 2 is fixedly connected to the top of the workbench 1. A cleaning component 8 is arranged on the left side of the gantry 2. A first hydraulic cylinder 3 is fixedly connected to the top of the gantry 2. And the telescopic end of the first hydraulic cylinder 3 located inside the gantry 2 is fixedly connected to a support frame 4. And a wire cutting component 5 is arranged in front of the support frame 4. The wire cutting component 5 is composed of two fixed wheels on the left and right and a cutting wire. The cutting wire is fixed between the two fixed wheels. Above the wire cutting component 5 is arranged a quick straightening mechanism, which includes:

[0026] A straightening component 7, sleeved outside the cutting wire in the wire cutting component 5. The straightening component 7 is used to straighten the cutting wire. The straightening component 7 includes a circular ring box 71. Four sector-shaped grooves 72 are equidistantly opened inside the circular ring box 71. Sliding grooves 73 communicating with the sector-shaped grooves 72 are opened on both the left and right sides of the circular ring box 71. And four groups of sector-shaped grooves 72 and sliding grooves 73 are equidistantly arranged. Guide rods 74 are slidably connected to the inner surfaces of the two sliding grooves 73. A U-shaped part 75 is fixedly connected between the two guide rods 74. Pressing wheels 76 are rotatably connected in the four U-shaped parts 75. Both the left and right sides of the circular ring box 71 are slidably connected with double-sector plates 77 through arc-shaped grooves and sliders. And the two double-sector plates 77 are arranged in a staggered manner. Two guide grooves 78 are opened on the double-sector plates 77. The two left guide grooves 78 are used to adjust the distance between the upper and lower pressing wheels 76. The two right guide grooves 78 are used to adjust the distance between the front and rear pressing wheels 76. Second hydraulic cylinders 79 are rotatably connected to both the left and right sides of the circular ring box 71. The telescopic ends of the second hydraulic cylinders 79 are rotatably connected to one side of the double-sector plates 77.

[0027] A driving component 6, arranged in front of the support frame 4. The driving component 6 is used to drive the straightening component 7 to reciprocate along the trajectory of the cutting wire. The driving component 6 includes two mounting seats 61 on the left and right. A lead screw 62 is rotatably connected between the two mounting seats 61. A driving motor 63 is fixedly connected to the left side of the left mounting seat 61. And the output end of the driving motor 63 is fixedly connected to one end of the lead screw 62. A connecting rod 64 is threadedly connected to the surface of the lead screw 62. And the connecting rod 64 is slidably connected to the front surface of the support frame 4. The other end of the connecting rod 64 is fixedly connected to the top of the straightening component 7. Two travel switches 65 are arranged on the front surface of the support frame 4.

[0028] When the cutting wire is deformed, the driving component 6 drives the straightening component 7 to move left and right to straighten the bent part of the steel wire, thereby avoiding the problem of irregular cutting and improving the practicability of the device during use.

[0029] Such as Figure 1The second implementation manner is shown, and the main difference from the first implementation manner is that: the cleaning component 8 includes a third hydraulic cylinder 81, and the third hydraulic cylinder 81 is fixedly connected to the left side of the gantry 2. The telescopic end of the third hydraulic cylinder 81 passing through to the inside of the gantry 2 is fixedly connected with a push plate 82. A placement rack 83 is fixedly connected to the top of the workbench 1, and a collection box 84 is placed on the placement rack 83.

[0030] After cutting, the cleaning component 8 is used to clean the surface of the conveyor belt in the workbench 1, thereby avoiding the problem of catalyst adhesion.

[0031] When it is necessary to straighten the cutting wire, first start the left second hydraulic cylinder 79. The start of the left second hydraulic cylinder 79 causes the double-sector plate 77 to rotate. The rotation of the double-sector plate 77 and the cooperation of the guide groove 78 and the guide rod 74 cause the two pressure wheels 76 to approach the upper and lower surfaces of the cutting wire. Start the drive motor 63 to make the lead screw 62 rotate. The rotation of the lead screw 62 causes the connecting rod 64 to move, so that the upper and lower pressure wheels 76 press on the cutting wire to move. After the guide rod 74 contacts the right travel switch 65, the drive motor 63 rotates in the reverse direction. At the same time, when the right second hydraulic cylinder 79 is started, the front and rear pressure wheels 76 straighten the front and back surfaces of the wire. After the catalyst cutting is completed, start the third hydraulic cylinder 81 to make the push plate 82 move, thereby cleaning the surface of the conveyor belt in the workbench 1. The scraped slag falls into the collection box 84 through the gap between the conveyor belt and the support of the workbench 1.
