In order to automatically prepare powder for the strip-shaped flat plate type denitration catalyst (namely, raw material), the two holders 11 capable of fixing the strip-shaped raw material are driven to rotate in opposite directions by a transmission device according to the existing manual operation mode, and the powder on the outer layer of the raw material matrix can be continuously dropped off by continuously twisting the raw material. To secure the two holders 11, it is also necessary to arrange structural supports 16 in the apparatus for supporting the holders 11 and the material.

Further, the transmission device comprises a first transmission device and a second transmission device; the first transmission device comprises a first driving wheel 5, a first driven wheel 4 driven by the first driving wheel 5, and a first rotating shaft 17 which is fixedly connected to the first driven wheel 4 and is coaxial with the first driven wheel; the second transmission device comprises a second driving wheel 8, an intermediate wheel 7 meshed with the second driving wheel 8, a second driven wheel 6 driven by the intermediate wheel 7, and a second rotating shaft 18 fixedly connected to the second driven wheel 6 and coaxial with the second driven wheel; the first driving wheel 5 and the second driving wheel 8 rotate synchronously when the device operates.

As shown in fig. 2, in the first transmission device, the lower first driving wheel 5 drives the first driven wheel 4 to rotate in the same direction, the first driven wheel 4 is provided with a first rotating shaft 17 coaxial with the first driven wheel 4, and the left gripper 11 is connected to the first rotating shaft 17, so that when the first driving wheel 5 rotates, the left gripper 11 is driven to rotate in the same direction. As shown in fig. 3, in the second transmission device, the lower second driving wheel 8 is a gear which drives the middle wheel 7 engaged with the gear to rotate, and the rotation direction of the middle wheel 7 is opposite to that of the second driving wheel 8 due to external engagement. Then, the middle wheel 7 drives the second driven wheel 6 to rotate in the same direction, the second driven wheel 6 is provided with a second rotating shaft 18 coaxial with the second driven wheel, and the right-hand clamper 11 is connected to the second rotating shaft 18, so that when the second driving wheel 8 rotates, the right-hand clamper 11 is driven to rotate in the opposite direction of the second driving wheel 8. Since the first drive wheel 5 is coaxial with the second drive wheel 8, their directions of rotation coincide, and consequently, the gripper 11 on the left side and the gripper 11 on the right side finally have opposite directions of rotation, and the two grippers 11 always have opposite directions of rotation regardless of the direction of rotation of the drive means 2.

Meanwhile, in order to prevent the catalyst from rotating too fast, the diameter of the second driven wheel 6 should be larger than that of the middle wheel 7, and the driving wheel and the driven wheel below; the diameter of the first driven wheel 4 should be larger than the first driving wheel 5.

Further, the output end of the driving device 2 is connected with a transmission shaft 10; the first driving wheel 5 and the second driving wheel 8 are respectively fixedly connected with the transmission shaft 10.

In order to output the power of the driving device 2 to the downstream transmission device, a transmission shaft 10 can be connected to the output end of the driving device 2 through a coupler, and both the first driving wheel 5 and the second driving wheel 8 can be fixedly connected to the transmission shaft 10.

Further, the transmission mode between the first driving wheel 5 and the first driven wheel 4 is belt transmission or chain transmission; the transmission mode between the intermediate wheel 7 and the second driven wheel 6 is belt transmission or chain transmission.

In order to realize the equidirectional rotation of the first driving wheel 5 and the first driven wheel 4, the first transmission chain 3 for connecting the first driving wheel and the first driven wheel is a belt or a chain; likewise, the second transmission chain 9 for connecting the intermediate wheel 7 and the second driven wheel 6 is a belt, or a chain.

Further, the clamper 11 comprises a pressing plate 21 and a screw 22 vertically arranged at the bottom of the pressing plate 21; the first revolving shaft 17 and the second revolving shaft 18 are both provided with threaded holes; the screw rod 22 is in threaded connection with the threaded hole; the holder 11 also includes a handle 23 at the top thereof.

The pressing plate 21 is used for pressing the strip-shaped raw material, and the up-down position of the clamper 11 needs to be adjusted during the pressing process, so that a screw 22 matched with the threaded hole is arranged below the pressing plate 21, and when a user operates, the clamper 11 can be rotated through the handle 23, so that the screw 22 is screwed into the threaded hole, and finally the pressing plate 21 is pressed on the upper surface of the raw material.

Further, the preparation device of the flat-plate denitration catalyst powder further comprises an equipment shell 15 and a base 14; the transmission and the two grippers 11 are both located inside the apparatus housing 15; the transmission device and the two grippers 11 are positioned on the base 14; the bottom of the device housing 15 is fixedly connected to the base 14.

In order to prevent the catalyst dust from flying and polluting the environment during the sample preparation process, a device shell 15 is arranged at the periphery of the device, so that the powder generation process is limited to be carried out in a closed interval. In order to facilitate observation of the operation of the apparatus and the powder growth, the apparatus case 15 is preferably made of a transparent material. For fixing the equipment housing 15 and supporting the components, such as the transmission and the holder 11, a base 14 should be provided at the bottom in the equipment.

Further, the device for preparing the flat-plate denitration catalyst powder further comprises two structural pillars 16 vertically arranged on the base 14 and spaced from left to right; the first swivel axis 17 is connected to the left structural strut 16 and the second swivel axis 18 is connected to the right structural strut 16.

In order to support the components inside the equipment housing 15, two structural supports 16 are fixed to the base 14, through holes are formed in the structural supports 16 at positions that are the same height as the first pivot shaft 17, and then the first pivot shaft 17 and the second pivot shaft 18 are inserted through the through holes in the structural supports 16 on the left and right sides, respectively. Since the first rotary shaft 17 and the second rotary shaft 18 are rotated after the device is pneumatically operated, a bearing can be additionally arranged between the through hole and the two rotary shafts.

Further, a sample receiving groove 13 is provided at the bottom of the inside of the device case 15.

To facilitate collection of the finished powder, a sample receiving groove 13, which is open at an upper portion and is located directly below the raw material, may be disposed inside the device housing 15.

Further, the driving device 2 is a speed reduction motor.

To control the driven wheel rotational speed, a reduction motor may be used to control the power output.

Further, the device for preparing the flat denitration catalyst powder further comprises a controller 1 electrically connected with the driving device 2.

Since the apparatus employs a reduction motor as a power source, a controller 1 should be provided for the driving device 2.

The left and right grippers 11 do not rotate all the time in one direction, otherwise the material is twisted off, therefore, after the grippers 11 rotate a proper angle, the control circuit makes the speed reducing motor reverse, so that the material is repeatedly twisted in the forward and reverse directions to simulate the manual operation mode.

The application process of preparing the flat plate type denitration catalyst powder by the device applied by the sample application is as follows:

step 1, selecting a strip-shaped flat plate type denitration catalyst (namely a raw material), wherein the length of the raw material is required to be longer than the distance between a left holder 11 and a right holder 11. Then, both ends of the raw material are placed at the left and right grippers 11, respectively, so that the lower surfaces thereof are placed above the first rotating shaft 17 and the second rotating shaft 18 and the upper surfaces thereof are close to the lower surfaces of the left and right pressing plates 21.

And 2, rotating a handle 23 at the top of the clamp holder 11 to enable the screw rod 22 to go deep into the threaded hole, so that the whole clamp holder 11 moves downwards, and after the lower surfaces of the pressure plates 21 on the left clamp holder 11 and the right clamp holder 11 are attached to the upper surface of the raw material, screwing the lower surfaces appropriately, so that the raw material is firmly clamped between the pressure plates 21 and the first rotating shaft 17 and the second rotating shaft 18, and the raw material is prevented from falling off after the equipment is started. The clamped state of the raw material is shown in fig. 4.

And 3, closing the cabinet door on the equipment shell 15, and setting the rotating speed of the speed reducing motor and the time interval of positive and negative rotation by using the controller 1.

And 4, starting the equipment. The driving device 2 then drives the first transmission device and the second transmission device to rotate through the transmission shaft 10, and finally the first revolving shaft 17 drives the left gripper 11 to rotate and the second revolving shaft 18 drives the right gripper 11 to rotate in the opposite direction due to the difference between the two sets of transmission devices. During the rotation, since the raw material is fixed at both ends and the rotation directions of both ends are reversed, the catalyst attached to the substrate falls off and falls into the sample receiving groove 13.

And 5, after the clamp 11 rotates for an angle, under the control of the controller 1, the driving device 2 rotates reversely, so that the left clamp 11 and the right clamp 11 are driven to rotate in the opposite directions. The catalyst attached to the substrate falls off again.

And 6, repeating the steps 4-5 to make the catalyst on the substrate fall off along with the continuous repeated reverse rotation of the two ends, and receiving the fallen catalyst powder by the sample receiving groove 13. And finishing the sample collection work after the catalyst on the base material completely falls off or reaches the preset time.
