Description

Technical Field

[0001] The present invention belongs to the technical field of denitration catalyst production equipment, and in particular relates to a denitration catalyst production equipment and a preparation method thereof. Background Art

[0002] Nowadays, denitration catalysts are often used for denitration treatment for the control of nitrogen oxides. In the prior art, after the denitration catalyst is extruded and formed by an extruder, it needs to be cut by a cutting device. The staff will transport the denitration agent squeezed out of the extruder to the cutting device through a conveying device for cutting. At this time, the denitration catalyst has just been extruded and formed, which is convenient for cutting. The denitration agent after cutting is also processed by drying and calcination, etc., to finally obtain the desired denitration agent finished product.

[0003] For example, a Chinese patent with application number CN201720528367.X discloses an automatic cutting device for SCR denitration catalyst; this technical solution controls the pneumatic pump to drive the bracket cylinder through the ground sensor coil signal, and drives the cutting knife to automatically cut the finished catalyst. During the entire cutting operation, no manual operation is required, and the automatic operation is fully realized, which has the effect of reducing work intensity and improving work efficiency; however, this technical solution does not completely solve the problem that during the slitting of the denitration catalyst strips, the conveyor belt needs to stop transporting and the extruder will also stop extruding. After the slitting is completed, the conveyor belt and the extruder will continue to run, thereby reducing the slitting efficiency of the denitration catalyst and the extrusion efficiency of the extruder, which greatly reduces the production efficiency of the denitration catalyst, thereby causing the limitations of this technical solution.

[0004] In view of this, the present invention proposes a denitration catalyst production device and a preparation method thereof, which solve the above technical problems. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes a denitration catalyst production device, comprising a slitting device; the slitting device also comprises a frame, a slitting module, a conveying module and a controller; the slitting module is installed at the upper end of the frame, and the slitting module comprises a screw rod and a light rod; the screw rod is rotatably connected to the frame, and the screw rod and the light rod are parallel; the light rod is fixedly connected to the frame; a drive motor is fixedly installed on one side of the frame, and the output end of the drive motor is fixedly connected to the screw rod; a slider is slidably connected between the screw rod and the light rod, and the slider is threadedly connected to the screw rod, and the screw rod, the light rod, the drive motor and the slider together constitute a screw slider pair; a hydraulic push rod is fixedly installed at the lower end of the slider, and a cutter is installed at the lower end of the hydraulic push rod; the conveying module is located below the slitting module, and the conveying module is fixedly installed with the frame; the controller is used to control the automatic operation of the entire slitting device;

[0006] In the prior art, during the slitting of the denitration catalyst strips, the conveyor belt needs to stop transporting and the extruder also stops extruding. After the slitting is completed, the conveyor belt and the extruder will continue to operate, thereby reducing the slitting efficiency of the denitration catalyst and the extrusion efficiency of the extruder, thereby greatly reducing the production efficiency of the denitration catalyst;

[0007] During operation, the staff controls the conveying module through the controller to convey the extruded denitration catalyst, so that the denitration catalyst moves between the cutter and the conveying module until the position of the denitration catalyst to be cut is located at the lower end of the cutter. At this time, the controller controls the drive motor to drive the screw rod to rotate, while driving the slider to move to the left at the same speed as the denitration catalyst, so that the slider and the denitration catalyst remain in a relatively static state. At this time, the controller controls the hydraulic push rod to push the cutter downward, so that the cutter cuts the denitration catalyst. After the cutter cuts off the denitration catalyst, the controller controls the hydraulic push rod to reset, so that the hydraulic push rod drives the cutter to rise until the cutter is located at the upper end of the denitration catalyst. The controller drives the motor to reverse, so that the drive motor drives the screw rod to rotate in the opposite direction and drives the slider to move to the right, and the speed of the reverse rotation of the drive motor is greater than the speed of the forward rotation of the drive motor.

[0008] The present invention arranges a lead screw slider pair so that the hydraulic push rod drives the cutter to move synchronously with the denitration catalyst, so that the cutter can cut the denitration catalyst during the movement of the denitration catalyst, thereby avoiding the conveying module and the extruder from stopping during the cutting process, thereby improving the cutting efficiency of the denitration catalyst and the extrusion efficiency of the extruder, thereby improving the production efficiency of the denitration catalyst.

[0009] Preferably, the conveying module is located below the slitting module, and the conveying module includes a No. 1 conveyor belt, a No. 2 conveyor belt and a roller; the No. 1 conveyor belt and the No. 2 conveyor belt are both installed on the inner wall of the frame; the roller is located between the No. 1 conveyor belt and the No. 2 conveyor belt, and the roller is rotatably connected to the inner wall of the frame; when working, the speed of the No. 2 conveyor belt is greater than the speed of the No. 1 conveyor belt. In the process of the cutter slitting the denitration catalyst, the No. 1 conveyor belt drives the denitration catalyst to move to the left. When the left end of the denitration catalyst contacts the roller, the hydraulic push rod pushes the cutter to start slitting the denitration catalyst. When the cutter cuts off the denitration catalyst, the slit denitration catalyst is completely located on the roller, and at this time The left end of the cut denitration catalyst is located on the No. 2 conveyor belt, so that the No. 2 conveyor belt drives the cut denitration catalyst to be quickly separated from the rear denitration catalyst. At this time, the hydraulic push rod quickly drives the cutter to reset quickly until the cutter is located at the upper end of the rear denitration catalyst. The controller drives the motor to reverse and drive the cutter to cut the rear denitration catalyst. The present invention cooperates between the No. 1 conveyor belt, the No. 2 conveyor belt and the roller, so that the cutter cuts the denitration catalyst on the roller, thereby avoiding the cutter contacting the No. 1 conveyor belt when cutting the denitration catalyst, causing damage to the No. 1 conveyor belt, thereby increasing the service life of the No. 1 conveyor belt, so that the actual application effect of the present invention is improved.

[0010] Preferably, an L-shaped plate is fixedly connected to the left side of the cutter; the L-shaped plate is fixedly connected to the lower end of the hydraulic push rod; the screw rod and the surface of the polished rod are slidably connected with an air bag, and a magnet is fixedly installed on the end of the air bag away from the slider; a groove is provided at the lower end of the L-shaped plate, and a slide plate is slidably and sealingly connected in the groove, and an air hole facing the cutter is provided on the surface of the slide plate, and the air hole is connected to the groove; an air pipe is provided at the upper end of the L-shaped plate, one end of the air pipe is connected to the air bag, and the other end passes through the L-shaped plate and is connected to the groove; an electromagnet is fixedly connected to the bottom of the groove; during operation, when the cutter cuts the denitration catalyst, the slide plate pushes the air bag to move to the left, and as the hydraulic push rod pushes the cutting plate and the L-shaped plate to move downward, the L-shaped plate drives the slide plate Move downward, at this time, the slide plate is located in the groove under the adsorption of the electromagnet, when the left end of the L-shaped plate contacts the left end of the denitration catalyst and slides downward along the left end of the denitration catalyst, the cutter cuts the denitration catalyst, and when the cutting is completed, since the left end of the denitration catalyst is located on the No. 2 conveyor belt, the No. 2 conveyor belt drives the cut denitration catalyst to quickly separate from the rear denitration catalyst, and the controller controls the driving motor to rotate faster, so that the moving speed of the slider is consistent with the cut denitration catalyst. At this time, the left end of the airbag contacts the frame, so that the magnet is adsorbed on the frame, and as the slider continues to move to the left, the airbag is squeezed, and the gas in the airbag enters the groove through the air pipe. At this time, the controller controls the hydraulic push rod to retract and controls the electromagnet to cut off the power. As the L-shaped plate continues to rise, the slide plate continues to extend from the groove, so that the gas in the groove is sprayed to the honeycomb hole of the cut denitration catalyst through the air hole. Because the cutter continues to rise under the pull of the hydraulic push rod, the honeycomb hole at the right end of the cut denitration catalyst is continuously opened, and the cutter cuts the denitration catalyst, so that the denitration catalyst residue generated by the cutting enters the honeycomb hole, so the gas blowing into the honeycomb hole will blow off the residue entering the right end of the honeycomb hole, avoiding the residue solidifying in the honeycomb hole during the baking process. When the hydraulic push rod pulls the cutter and the L-shaped plate to be located above the denitration catalyst, the controller controls the electromagnet to adsorb The iron slide plate enters the groove, and the controller controls the driving motor to reverse and move the slider to the right, so that the slider pulls the rubber airbag to recover. When the airbag is fully restored, the slider continues to pull the airbag to the right, so that the magnet is separated from the frame under the pull of the airbag; the present invention cooperates with the L-shaped plate and the airbag so that the gas in the airbag can be sprayed into the honeycomb holes of the denitration catalyst. On the one hand, the gas can clean the honeycomb holes of the denitration catalyst, and on the other hand, the moisture in the honeycomb holes of the denitration catalyst is reduced, thereby accelerating the air-drying speed of the denitration catalyst, which not only facilitates the manual transportation of the denitration catalyst and the drying treatment of the denitration catalyst, but also improves the efficiency of the drying treatment of the denitration catalyst.

[0011] Preferably, a spring is provided in the groove, one end of the spring is fixedly connected to the bottom of the groove, and the other end is fixedly connected to the slide plate; during operation, when the cutter cuts the denitration catalyst, the electromagnet in the groove adsorbs the iron slide plate, so that the slide plate squeezes the spring in the groove, causing the spring to be compressed. At this time, the slide plate is not completely entered into the groove under the combined effect of the elastic restoring force of the compressed spring and its own gravity. At this time, the last exhaust hole at the lower end of the slide plate exposes the groove, and when the cutter contacts the denitration catalyst, the airbag contacts the frame and is squeezed by the slider. At this time, the last exhaust hole at the lower end of the slide plate is opposite to the top row of honeycomb holes of the denitration catalyst, so that the gas in the airbag is blown to the honeycomb holes through the last exhaust hole at the lower end of the slide plate, so that the honeycomb holes are filled with gas, so that the gas supports the inner wall of the honeycomb holes, thereby avoiding the cutter cutting the denitration catalyst and causing the top end face of the denitration catalyst to collapse, and preventing the aperture of the top row of honeycomb holes of the denitration catalyst from being reduced, so that the ventilation effect of the denitration catalyst is improved, and then the practical application effect of the present invention is effectively improved.

[0012] Preferably, the end of the air hole away from the groove is set to be trumpet-shaped; during operation, when the airbag is compressed, the gas in the airbag enters the groove through the air pipe, so that the gas entering the groove is sprayed from the airbag to the honeycomb hole of the denitration catalyst. Since the end of the air hole away from the groove is set to be trumpet-shaped, the diameter of the end of the air hole close to the groove is larger than the diameter of the air hole at the end away from the groove, and because the slider squeezes the airbag, the amount of airbag sprayed through the air hole remains unchanged, so the diameter of the air hole is reduced, so that the gas spraying speed in the air hole is increased, and the gas impact force is increased, so that the amount of gas dissipated through the gap between the honeycomb holes of the slide plate denitration catalyst is reduced; the amount of gas rushing into the honeycomb hole of the denitration catalyst is increased, and the gas content in the honeycomb hole of the denitration catalyst is high, which not only improves the supporting effect of the gas on the inner wall of the honeycomb hole, but also makes the impact force of the gas on the residue in the honeycomb hole increase without the obstruction of the cutter after the cutter rises, which accelerates the separation of the residue in the honeycomb hole from the honeycomb hole, and the increase in gas flow rate accelerates the air drying speed of the denitration catalyst, thereby further improving the practical application effect of the present invention.

[0013] The method for preparing a denitration catalyst according to the present invention is applicable to the above-mentioned denitration catalyst production device, and the steps of the method are as follows:

[0014] S1: The staff will take out the following raw materials in weight ratio and add them into the mixer: 80-100 parts of titanium dioxide, 7-10 parts of tungsten trioxide, 1-3 parts of glass fiber and 1-2 parts of deionized water; start the mixer and control the temperature at 80-110°C, and carry out aging for 1-1.5 hours. After aging, open the mixer, control the mixing temperature to 50-55°C, add 3-5 parts of vanadium pentoxide and 2-5 parts of adhesive, close the mixer, and mix for 40-60 minutes to obtain the denitration catalyst raw material;

[0015] S2: Put the denitration catalyst raw material into the extrusion molding machine, so that the extrusion molding machine extrudes the denitration catalyst into shape, and the denitration catalyst just extruded into shape is conveyed to the No. 1 conveyor belt through the roller, so that the No. 1 conveyor belt drives the denitration catalyst to move to the left. When the left end of the denitration catalyst contacts the roller, the position of the denitration catalyst to be cut is located at the lower end of the cutter. At this time, the cutter moves to the left under the control of the controller, so that the cutter and the denitration catalyst remain in a relatively static state, and the hydraulic push rod drives the cutter and the L-shaped plate to move downward synchronously;

[0016] S3: When the cutter contacts the denitration catalyst, the airbag contacts the frame under the push of the slide plate. At this time, the airbag is squeezed, and the gas in the airbag enters the groove through the air pipe, and then sprays into the honeycomb hole of the denitration catalyst from the last exhaust hole at the lower end of the slide plate. When the cutter cuts off the denitration catalyst, the left end of the denitration catalyst is located on the No. 2 conveyor belt, so that the denitration catalyst moves rapidly to the left under the drive of the No. 2 conveyor belt. At this time, the controller controls the driving motor to rotate faster, so that the cutter and the denitration catalyst maintain the same speed, and the electromagnet is powered off at this time, and the hydraulic push rod pulls the cutter and the L-shaped plate to rise;

[0017] S4: During the resetting process of the hydraulic push rod, the cutter and the L-shaped plate rise, so that the slide plate extends out of the groove, and the cutter no longer blocks the honeycomb hole at the right end of the denitration catalyst. The slide plate drives the air holes on it to extend out of the groove and face the honeycomb hole until the cutter is located above the denitration catalyst. The controller controls the electromagnet to adsorb the slide plate to rise. When the slide plate moves to the top of the denitration catalyst, the controller controls the driving motor to reverse, so that the cutter moves to the right under the drive of the slider, so that the cutter can cut the denitration catalyst at the rear.

[0018] S5: The staff will dry and calcine the cut small sections of denitrification catalyst to finally obtain the finished denitrification catalyst.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The slitting device used in the present invention is configured with a lead screw slider pair so that the hydraulic push rod drives the cutter to move synchronously with the denitration catalyst, so that the cutter can cut the denitration catalyst during the movement of the denitration catalyst, thereby avoiding the conveying module and the extruder from stopping during the cutting process, thereby improving the cutting efficiency of the denitration catalyst and the extrusion efficiency of the extruder, thereby improving the production efficiency of the denitration catalyst.

[0021] 2. The slitting device used in the present invention cooperates between the No. 1 conveyor belt, the No. 2 conveyor belt and the roller, so that the cutter cuts the denitration catalyst on the roller, thereby avoiding the contact between the cutter and the No. 1 conveyor belt when the cutter cuts the denitration catalyst, causing damage to the No. 1 conveyor belt, thereby increasing the service life of the No. 1 conveyor belt, and improving the practical application effect of the present invention.

[0022] 3. The slitting device used in the present invention cooperates with the airbag through the L-shaped plate, so that the gas in the airbag can be sprayed into the honeycomb holes of the denitration catalyst. On the one hand, the gas can clean the honeycomb holes of the denitration catalyst, and on the other hand, the moisture in the honeycomb holes of the denitration catalyst is reduced, thereby accelerating the air-drying speed of the denitration catalyst. This not only facilitates the manual transportation of the denitration catalyst and the drying treatment of the denitration catalyst, but also improves the efficiency of the drying treatment of the denitration catalyst.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 4 As shown, a denitration catalyst production device described in the present invention includes a slitting device; the slitting device also includes a frame 1, a slitting module 2, a conveying module 3 and a controller; the slitting module 2 is installed at the upper end of the frame 1, and the slitting module 2 includes a screw rod 21 and a light rod 22; the screw rod 21 is rotatably connected to the frame 1, and the screw rod 21 and the light rod 22 are parallel; the light rod 22 is fixedly connected to the frame 1; a drive motor 23 is fixedly installed on one side of the frame 1, and the output end of the drive motor 23 is fixedly connected to the screw rod 21; a slider 24 is slidably connected between the screw rod 21 and the light rod 22, and the slider 24 is threadedly connected to the screw rod 21, and the screw rod 21, the light rod 22, the drive motor 23 and the slider 24 together constitute a screw slider pair; a hydraulic push rod 25 is fixedly installed at the lower end of the slider 24, and a cutter 26 is installed at the lower end of the hydraulic push rod 25; the conveying module 3 is located below the slitting module 2, and the conveying module 3 is fixedly installed with the frame 1; the controller is used to control the automatic operation of the entire slitting device;

[0031] In the prior art, during the slitting of the denitration catalyst strips, the conveyor belt needs to stop transporting and the extruder also stops extruding. After the slitting is completed, the conveyor belt and the extruder will continue to operate, thereby reducing the slitting efficiency of the denitration catalyst and the extrusion efficiency of the extruder, thereby greatly reducing the production efficiency of the denitration catalyst;

[0032] During operation, the staff controls the conveying module 3 through the controller to convey the extruded denitration catalyst, so that the denitration catalyst moves between the cutter 26 and the conveying module 3 until the position of the denitration catalyst to be cut is located at the lower end of the cutter 26. At this time, the controller controls the drive motor 23 to drive the screw rod 21 to rotate, while driving the slider 24 to move to the left at the same speed as the denitration catalyst, so that the slider 24 and the denitration catalyst remain in a relatively static state. At this time, the controller controls the hydraulic push rod 25 to push the cutter 26 to move downward, so that the cutter 26 cuts the denitration catalyst. After the cutter 26 cuts the denitration catalyst, the controller controls the hydraulic push rod 25 to reset, so that the hydraulic push rod 25 drives the cutter 26 to rise until the cutter 26 is located at the upper end of the denitration catalyst. The controller drives the motor 23 to reverse, so that the drive motor 23 drives the screw rod 21 to rotate in the opposite direction while driving the slider 24 to move to the right, and the speed of the reverse rotation of the drive motor 23 is greater than the speed of the forward rotation of the drive motor 23.

[0033] The present invention arranges the lead screw slider pair so that the hydraulic push rod 25 drives the cutter 26 to move synchronously with the denitration catalyst, so that the cutter 26 can cut the denitration catalyst during the movement of the denitration catalyst, thereby avoiding the conveying module 3 and the extruder from stopping during the cutting process, thereby improving the cutting efficiency of the denitration catalyst and the extrusion efficiency of the extruder, thereby improving the production efficiency of the denitration catalyst.

[0034] As an embodiment of the present invention, the conveying module 3 is located below the slitting module 2, and the conveying module 3 includes a No. 1 conveyor belt 31, a No. 2 conveyor belt 32 and a roller 33; the No. 1 conveyor belt 31 and the No. 2 conveyor belt 32 are both installed on the inner wall of the frame 1; the roller 33 is located between the No. 1 conveyor belt 31 and the No. 2 conveyor belt 32, and the roller 33 is rotatably connected to the inner wall of the frame 1; when working, the speed of the No. 2 conveyor belt 32 is greater than the speed of the No. 1 conveyor belt 31, and the cutter 26 During the process of cutting the denitration catalyst, the No. 1 conveyor belt 31 drives the denitration catalyst to move to the left. When the left end of the denitration catalyst contacts the roller 33, the hydraulic push rod 25 pushes the cutter 26 to start cutting the denitration catalyst. When the cutter 26 cuts the denitration catalyst, the cut denitration catalyst is completely located on the roller 33, and the left end of the cut denitration catalyst is located on the No. 2 conveyor belt 32, so that the No. 2 conveyor belt 32 drives the cut denitration catalyst to be quickly separated from the rear denitration catalyst. At this time, the hydraulic push rod 25 quickly drives the cutter 26 to reset quickly until the cutter 26 When it is located at the upper end of the rear denitration catalyst, the controller drives the motor 23 to reverse, thereby driving the cutter 26 to cut the rear denitration catalyst; the present invention cooperates between the No. 1 conveyor belt 31, the No. 2 conveyor belt 32 and the roller 33, so that the cutter 26 cuts the denitration catalyst on the roller 33, thereby avoiding the contact between the cutter 26 and the No. 1 conveyor belt 31 when the cutter 26 cuts the denitration catalyst, causing the No. 1 conveyor belt 31 to be damaged, thereby increasing the service life of the No. 1 conveyor belt 31, so that the actual application effect of the present invention is improved.

[0035] As an embodiment of the present invention, an L-shaped plate 4 is fixedly connected to the left side of the cutter 26; the L-shaped plate 4 is fixedly connected to the lower end of the hydraulic push rod 25; the screw rod 21 and the surface of the polished rod 22 are slidably connected with an air bag 5, and the end of the air bag 5 away from the slider 24 is fixedly installed with a magnet 52; the lower end of the L-shaped plate 4 is provided with a groove 41, and a slide plate 42 is slidably and sealedly connected in the groove 41, and an air hole 421 facing the cutter 26 is provided on the surface of the slide plate 42, and the air hole 421 is connected to the groove 41; the upper end of the L-shaped plate 4 is provided with an air pipe 51, one end of the air pipe 51 is connected to the air bag 5, and the other end passes through the L-shaped plate 4 and the groove 41 The bottom of the groove 41 is connected; an electromagnet 43 is fixedly connected to the bottom of the groove 41; during operation, when the cutter 26 cuts the denitration catalyst, the slide plate 42 pushes the airbag 5 to move to the left, and as the hydraulic push rod 25 pushes the cutting plate and the L-shaped plate 4 to move downward, the L-shaped plate 4 drives the slide plate 42 to move downward. At this time, the slide plate 42 is located in the groove 41 under the adsorption of the electromagnet 43. When the left end of the L-shaped plate 4 contacts the left end of the denitration catalyst and slides downward along the left end of the denitration catalyst, the cutter 26 cuts the denitration catalyst. When the cutting is completed, since the left end of the denitration catalyst is located on the No. 2 conveyor belt 32, the No. 2 conveyor belt 32 drives the cut denitration catalyst to be quickly separated from the rear denitration catalyst, and the controller controls the driving motor 23 to rotate faster, so that the moving speed of the slider 24 is consistent with the cut denitration catalyst. At this time, the left end of the airbag 5 contacts the frame 1, so that the magnet 52 is adsorbed on the frame 1, and as the slider 24 continues to move to the left, the airbag 5 The gas in the airbag 5 enters the groove 41 through the air pipe 51, and the controller controls the hydraulic push rod 25 to contract and controls the electromagnet 43 to cut off the power. As the L-shaped plate 4 continues to rise, the slide plate 42 continues to extend from the groove 41, so that the gas in the groove 41 is sprayed to the honeycomb hole of the cut denitration catalyst through the air hole 421. Because the cutter 26 continues to rise under the pull of the hydraulic push rod 25, the honeycomb hole at the right end of the cut denitration catalyst is continuously opened, and the cutter 26 cuts the denitration catalyst, so that the denitration catalyst residue generated by the cutting enters the honeycomb hole, so the gas blowing into the honeycomb hole will blow off the residue entering the right end of the honeycomb hole, so as to avoid the residue solidifying in the honeycomb hole during the baking process. When the hydraulic push rod 25 pulls the cutter 26 and the L-shaped plate 4 to be located above the denitration catalyst, the controller controls the electromagnet 43 to adsorb the iron slide plate 42 to enter the groove 41, and the controller controls the drive motor 23 to reverse, so that the slider 24 moves to the right, so that the slider 24 Pull the rubber airbag 5 to recover. When the airbag 5 is fully recovered, the slider 24 continues to pull the airbag 5 to move rightward, so that the magnet 52 is separated from the frame 1 under the pull of the airbag 5.The present invention cooperates with the L-shaped plate 4 and the airbag 5 so that the gas in the airbag 5 can be sprayed into the honeycomb holes of the denitration catalyst. On the one hand, the gas can clean the honeycomb holes of the denitration catalyst. On the other hand, the moisture in the honeycomb holes of the denitration catalyst is reduced, and the air drying speed of the denitration catalyst is accelerated. It is not only convenient for manual transportation of the denitration catalyst, but also convenient for drying the denitration catalyst, and the efficiency of drying the denitration catalyst is also improved. ;

[0036] As an embodiment of the present invention, a spring 44 is provided in the groove 41, one end of the spring 44 is fixedly connected to the bottom of the groove 41, and the other end is fixedly connected to the slide plate 42; when working, when the cutter 26 cuts the denitration catalyst, the electromagnet 43 in the groove 41 adsorbs the iron slide plate 42, so that the slide plate 42 squeezes the spring 44 in the groove 41, so that the spring 44 is compressed. At this time, the slide plate 42 is subjected to the elastic restoring force of the compressed spring 44 and its own gravity, so that the slide plate 42 does not completely enter the groove 41. At this time, the last exhaust hole 421 at the lower end of the slide plate 42 is exposed from the groove 41. When the cutter 26 and the denitration catalyst are cut, the electromagnet 43 in the groove 41 adsorbs the iron slide plate 42, so that the slide plate 42 squeezes the spring 44 in the groove 41, so that the spring 44 is compressed. When the catalyst contacts, the airbag 5 contacts the frame 1 and is squeezed by the slider 24. At this time, the last exhaust hole 421 at the lower end of the slider 42 is opposite to the honeycomb holes in the top row of the denitration catalyst, so that the gas in the airbag 5 is blown toward the honeycomb holes through the last exhaust hole 421 at the lower end of the slider 42, so that the honeycomb holes are filled with gas, so that the gas supports the inner wall of the honeycomb holes, thereby avoiding the cutter 26 cutting the denitration catalyst and causing the top end face of the denitration catalyst to collapse, preventing the aperture of the top row of honeycomb holes of the denitration catalyst from decreasing, so that the ventilation effect of the denitration catalyst is improved, and then the practical application effect of the present invention is effectively improved.

[0037] As an embodiment of the present invention, the end of the air hole 421 away from the groove 41 is set in a trumpet shape; when working, when the airbag 5 is compressed, the gas in the airbag 5 enters the groove 41 through the air pipe 51, so that the gas entering the groove 41 is sprayed from the air hole 421 to the honeycomb hole of the denitration catalyst. Since the end of the air hole 421 away from the groove 41 is set in a trumpet shape, the diameter of the end of the air hole 421 close to the groove 41 is larger than the diameter of the air hole 421 at the end away from the groove 41, and because the slider 24 squeezes the airbag 5, the amount of the airbag 5 sprayed through the air hole 421 remains unchanged, so the diameter of the air hole 421 is reduced, so that the air hole 421 is 1. The gas ejection speed increases, so that the gas impact force increases, thereby reducing the amount of gas dissipated through the gaps between the denitration catalyst honeycomb holes of the slide plate 43; the amount of gas rushing into the denitration catalyst honeycomb holes increases, so that the gas content in the denitration catalyst honeycomb holes is high, which not only improves the supporting effect of the gas on the inner wall of the honeycomb hole, but also increases the impact force of the gas on the residue in the honeycomb hole without the obstruction of the cutter 26 after the cutter 26 rises, which accelerates the separation of the residue in the honeycomb hole from the honeycomb hole, and the increase in the gas flow rate accelerates the air drying speed of the denitration catalyst, thereby further improving the practical application effect of the present invention.

[0038] The method for preparing a denitration catalyst according to the present invention is applicable to the above-mentioned denitration catalyst production device, and the steps of the method are as follows:

[0039] S1: The staff will take out the following raw materials in weight ratio and add them into the mixer: 80-100 parts of titanium dioxide, 7-10 parts of tungsten trioxide, 1-3 parts of glass fiber and 1-2 parts of deionized water; start the mixer and control the temperature at 80-110°C, and carry out aging for 1-1.5 hours. After aging, open the mixer, control the mixing temperature to 50-55°C, add 3-5 parts of vanadium pentoxide and 2-5 parts of adhesive, close the mixer, and mix for 40-60 minutes to obtain the denitration catalyst raw material;

[0040] S2: Put the denitration catalyst raw material into the extrusion molding machine, so that the extrusion molding machine extrudes the denitration catalyst, and the denitration catalyst just extruded is conveyed to the No. 1 conveyor belt 31 through the roller, so that the No. 1 conveyor belt 31 drives the denitration catalyst to move to the left. When the left end of the denitration catalyst contacts the roller 33, the position of the denitration catalyst to be cut is located at the lower end of the cutter 26. At this time, the cutter 26 moves to the left under the control of the controller, so that the cutter 26 and the denitration catalyst remain in a relatively static state, and the hydraulic push rod 25 pushes the cutter 26 and the L-shaped plate 4 to move downward synchronously;

[0041] S3: When the cutter 26 contacts the denitration catalyst, the airbag 5 contacts the frame 1 under the push of the slide 42. At this time, the airbag 5 is squeezed, and the gas in the airbag 5 enters the groove 41 through the air pipe 51, and then sprays into the honeycomb hole of the denitration catalyst from the last exhaust hole 421 at the lower end of the slide 42. When the cutter 26 cuts off the denitration catalyst, the left end of the denitration catalyst is located at the No. 2 conveyor belt 32, so that the denitration catalyst moves rapidly to the left under the drive of the No. 2 conveyor belt 32. At this time, the controller controls the driving motor 23 to rotate faster, so that the cutter 26 and the denitration catalyst maintain the same speed, and at this time the electromagnet 43 is powered off, and the hydraulic push rod 25 pulls the cutter 26 and the L-shaped plate 4 up;

[0042] S4: During the resetting process of the hydraulic push rod 25, the cutter 26 and the L-shaped plate 4 rise, so that the slide plate 42 extends out of the groove 41, and the cutter 26 no longer blocks the honeycomb hole at the right end of the denitration catalyst. The slide plate 42 drives the air holes 421 thereon to extend out of the groove 41 and face the honeycomb hole, until the cutter 26 is located above the denitration catalyst. The controller controls the electromagnet 43 to adsorb the slide plate 42 and rise. When the slide plate 42 moves to the top of the denitration catalyst, the controller controls the driving motor 23 to reverse, so that the cutter 26 moves to the right under the drive of the slider 24, so that the cutter 26 can cut the denitration catalyst at the rear.

[0043] S5: The staff will dry and calcine the cut small sections of denitrification catalyst to finally obtain the finished denitrification catalyst.

[0044] The specific workflow is as follows:

[0045] The staff controls the conveying module 3 through the controller to convey the extruded denitration catalyst, so that the denitration catalyst moves between the cutter 26 and the conveying module 3 until the denitration catalyst to be cut is located at the lower end of the cutter 26. At this time, the controller controls the drive motor 23 to drive the screw rod 21 to rotate, while driving the slider 24 to move left at the same speed as the denitration catalyst, so that the slider 24 and the denitration catalyst remain in a relatively static state. At this time, the controller controls the hydraulic push rod 25 to push the cutter 26 to move downward, so that the cutter 26 cuts the denitration catalyst. When the cutter 26 cuts the denitration catalyst, the controller controls the hydraulic push rod 25 to reset, so that the hydraulic push rod 25 drives the cutter 26 to rise until the cutter 26 When it is located at the upper end of the denitration catalyst, the controller drives the motor 23 to reverse, so that the drive motor 23 drives the screw rod 21 to rotate in the opposite direction and drives the slider 24 to move to the right, and the speed of the reverse rotation of the drive motor 23 is greater than the speed of the forward rotation of the drive motor 23; the speed of the No. 2 conveyor belt 32 is greater than the speed of the No. 1 conveyor belt 31. In the process of the cutter 26 cutting the denitration catalyst, the No. 1 conveyor belt 31 drives the denitration catalyst to move to the left. When the left end of the denitration catalyst contacts the roller 33, the hydraulic push rod 25 pushes the cutter 26 to contact the opening The denitration catalyst begins to be cut. When the cutter 26 cuts the denitration catalyst, the cut denitration catalyst is completely located on the roller 33, and the left end of the cut denitration catalyst is located on the No. 2 conveyor belt 32, so that the No. 2 conveyor belt 32 drives the cut denitration catalyst to be quickly separated from the rear denitration catalyst. At this time, the hydraulic push rod 25 quickly drives the cutter 26 to reset quickly, until the cutter 26 is located at the upper end of the rear denitration catalyst, the controller drives the motor 23 to reverse, thereby driving the cutter 26 to cut the rear denitration catalyst.
