Description

Technical Field

[0001] The invention relates to the technical field of catalyst production, and in particular to an anti-sticking extrusion device and an extrusion process for catalyst production. Background Art

[0002] A catalyst is a substance that can change the reaction rate of other substances in a chemical reaction without undergoing permanent changes itself before and after the reaction. It is widely used in industries such as industry and environmental management, and plays an irreplaceable role in improving production efficiency, reducing energy consumption, and controlling environmental pollution.

[0003] Common production methods for catalysts include precipitation method, impregnation method, extrusion molding method, etc. Among them, the extrusion molding method is to use an extrusion device to make catalyst powder into catalyst strips with a specific shape and fixed size to facilitate the use and transportation of the catalyst. However, catalyst powder is generally not sticky, and the existing catalyst strips fall off from the forming holes by their own gravity. However, the different composition and humidity of some catalyst powders will affect the fracture position, which will lead to different lengths of the catalyst strips. The friction force on the catalyst strips will be reduced when they are separated from the forming holes, making the fracture position loose due to the sudden loss of friction, resulting in an uneven surface at the fracture point when the fracture occurs. In the subsequent transportation process, the fracture point is prone to stress concentration when in contact with other catalyst strips to produce catalyst powder, resulting in waste of catalyst strip materials.

[0028] When catalyst powder is added into the lower barrel 701, the telescopic parts of the four spring telescopic members 3 are driven to move downward according to the weight of the catalyst powder that falls into the first discharging rack 7 through the lower barrel 701, and the downward movement of the telescopic parts of the four spring telescopic members 3 drives the bracket 4 to move downward, and the downward movement of the bracket 4 drives the other parts of the bracket 4 except the sliding pin 2101, the second spring 2102, the fixing ring 2103, the rotating column 2104 and the shielding member 2105 to move downward, and the first transmission shaft 2 keeps the fixing ring 2103 at the current position through the sliding pins 2101 evenly distributed in the circumference, and keeps the rotating column 2104 and the shielding member 2105 at the current position, and the shielding member 2105 slides relative to the adjacent jet member 2004, gradually releasing the shielding member 2105 from blocking the jet hole on the adjacent jet member 2004, increasing the jet amount of the jet member 2004, and ensuring that the jet amount of the jet hole of the jet member 2004 is controlled according to the weight of the catalyst powder. To adjust the jet effect, the three third gears 2003 rotate to drive the adjacent blocking members 2105 to rotate respectively, the blocking members 2105 rotate to drive the adjacent rotating columns 2104 to rotate, the three rotating columns 2104 rotate to jointly drive the fixing ring 2103 to rotate, the fixing ring 2103 drives the several sliding pins 2101 evenly distributed in the circumferential direction to rotate, the inclined surfaces of the several sliding pins 2101 evenly distributed in the circumferential direction are respectively squeezed and matched with the adjacent fixed columns 2001 during the rotation process, the sliding pin 2101 is squeezed to slide in the direction away from the first transmission shaft 2, and the rotation limit of the fixing ring 2103 is released, and after passing the adjacent fixed columns 2001, the sliding pin 2101 slides and resets in the direction close to the first transmission shaft 2 under the action of the spring force, and the rotation speed of the fixing ring 2103 is the same as the rotation speed of the first transmission shaft 2, which is used to ensure that the sliding pin 2101 can slide into the first transmission shaft 2 when one end of the sliding pin 2101 is reset close to the first transmission shaft 2.

[0029] As the pressure roller 9 continuously squeezes the catalyst powder, the catalyst powder is gradually squeezed out from the forming holes of the first discharging rack 7 and the second discharging rack 18 to form materials, and the first pulley 11 is driven to rotate by the second transmission shaft 10, and the first pulley 11 drives the second pulley 12 to rotate through the belt, and the second pulley 12 drives the first gear 14 to rotate through the third transmission shaft 13, and the first gear 14 drives the rotating member 16 to rotate, and the rotating member 16 drives the three extrusion columns 17 to rotate, and the three extrusion columns 17 rotate to squeeze the adjacent limit blocks 21 respectively, so that the three limit blocks 21 move downward, and the three limit blocks 21 move downward to drive the annular blade 20 to move downward, and the annular blade 20 moves downward to squeeze the four first springs 19 to contract and accumulate force, so as to cut the material. The cut material falls on the material transport plate 2302, and after the annular blade 20 passes through a number of circumferentially evenly distributed forming holes on the second discharging rack 18, the three extrusion columns 17 continue to squeeze the adjacent limit blocks 21 to seal the several circumferentially evenly distributed forming holes on the second discharging rack 18, and cooperate with the three pressing rollers 9 to squeeze the catalyst powder to further improve the compactness of the catalyst powder in the forming holes. As the three extrusion columns 17 pass through the adjacent limit blocks 21 respectively, the extrusion of the adjacent limit blocks 21 by the extrusion columns 17 is gradually released, and the annular blade 20 moves upward and resets under the action of the elastic force of the four first springs 19. As the second transmission shaft 10 continues to rotate, the annular blade 20 realizes intermittent cutting of the material and intermittent sealing of the forming holes.

[0030] Subsequently, the third transmission shaft 13 rotates to drive the fourth gear 2301 to rotate, the fourth gear 2301 drives the material transporting plate 2302 to rotate, the material transporting plate 2302 rotates to drive the sixth gear 2307 to rotate, the sixth gear 2307 drives the fifth gear 2304 to rotate, the fifth gear 2304 drives the unloading piece 2305 to rotate, the material transporting plate 2302 rotates to drive the material to rotate, and the material contacts the adjacent first baffle 2303 during rotation, thereby changing its direction, reducing the rolling phenomenon that occurs when one end of the material revolves toward the center of the material transporting plate 2302. As the material transporting plate 2302 rotates, the material contacts the unloading piece 2305 in turn, and the unloading piece 2305 pushes the material from the material transporting plate 2302 to the inclined plate of the second baffle 2306 through the arc-shaped blades for unloading, thereby realizing the collection of the cut material.

[0031] When the device is stopped, the staff first stops unloading and waits for the catalyst powder in the first discharging rack 7 to be used up. At this time, the telescopic parts of the four spring telescopic parts 3 move upward, driving the bracket 4 to move upward. The upward movement of the bracket 4 drives the other parts of the bracket 4 except the sliding pin 2101, the second spring 2102, the fixed ring 2103, the rotating column 2104 and the shielding member 2105 to move upward. The first transmission shaft 2 keeps the fixed ring 2103 in the current position through the circumferentially evenly distributed sliding pins 2101, so that the rotating column 2104 and the shielding member 2105 keep the current position, and the shielding member 2105 slides relative to the adjacent injection member 2004, so that the shielding member 2105 blocks the injection hole on the adjacent injection member 2004, and then the inflation device and the motor are turned off.

[0032] Embodiment 2: Based on embodiment 1, Figure 5 , Fig.12 and Fig.13 As shown, a cooling assembly is also included, and the cooling assembly is arranged in the second discharging rack 18. The cooling assembly is used to cool the material. The cooling assembly includes a plurality of telescopic rods 2201 evenly distributed circumferentially. An air bag is fixedly connected to the outer side of the fixed plate 5 for protecting the material. The fixed parts of the telescopic rods 2201 evenly distributed circumferentially are all connected to the air bag. The plurality of telescopic rods 2201 evenly distributed circumferentially are all arranged in the second discharging rack 18. The telescopic ends of the plurality of telescopic rods 2201 evenly distributed circumferentially are all fixedly connected to the lower side of the annular blade 20. The fixing parts of the plurality of telescopic rods 2201 evenly distributed circumferentially are all connected to the air bag. The second discharging rack 18 is provided with a plurality of ventilation grooves 2203 which are symmetrically and evenly distributed circumferentially. The annular blade 20 is sealed and cooperated with the plurality of ventilation grooves 2203 which are evenly distributed circumferentially, so as to fill the gas in the fixed part of the plurality of telescopic rods 2201 which are evenly distributed circumferentially into the airbag fixedly connected to the outer side of the fixed disk 5. The symmetrically distributed ventilation grooves 2203 are respectively located on both sides of the adjacent forming holes of the second discharging rack 18, and the insulation tubes 2202 are connected with the adjacent ventilation grooves 2203.

[0033] like Fig.13As shown, the ventilation slots 2203 are arranged as inclined slots, and the distance between the two symmetrically distributed ventilation slots 2203 gradually decreases from the direction close to the axis of the second discharge rack 18 to the direction away from the axis of the second discharge rack 18, which is used to cool the material just extruded. The blades uniformly distributed circumferentially on the discharge piece 2305 are all arranged in an arc shape, and one group of ventilation slots 2203 opens toward the adjacent discharge piece 2305. The wind blown out of this group of ventilation slots 2203 passes through the arc surface of the arc blade. When the wind flow direction is tangent to the corresponding arc of the arc blade, the waste on the surface of the arc blade is easier to fall off, thereby cleaning the blades uniformly distributed circumferentially on the discharge piece 2305. The other groups of ventilation slots 2203 are used to blow wind onto the material extruded from the forming hole of the discharge rack 18 to cool the material just extruded.

[0034] According to the above action, the second transmission shaft 10 rotates to drive the annular blade 20 to move downward, and the annular blade 20 drives the telescopic parts of the telescopic rods 2201 evenly distributed in the circumference to move downward, and blows the gas in the telescopic rods 2201 through two adjacent insulation tubes 2202 and two adjacent ventilation slots 2203 to cool the material, and the wind blown out from a group of ventilation slots 2203 close to the discharge piece 2305 passes through the surface of the arc-shaped blades of the discharge piece 2305 to clean the arc-shaped blades. When the annular blade 20 moves downward to completely cover the several ventilation slots 2203 evenly distributed in the circumference, the gas in the circumferentially evenly distributed telescopic rods 2201 enters the airbag through the lower pipe, inflates the airbag, and makes the airbag expand. The annular blade 20 continues to move downward to completely cut off the material, and the material falls on the airbag, thereby achieving the protection of the material. When the three extrusion columns 17 pass through the adjacent limit blocks 21 respectively, the extrusion of the adjacent limit blocks 21 by the extrusion columns 17 is gradually released, and the annular blade 20 moves upward under the action of the elastic force of the four first springs 19 distributed circumferentially. When the annular blade 20 moves upward, it drives the telescopic parts of the several telescopic rods 2201 evenly distributed circumferentially to move upward, and the telescopic parts of the several telescopic rods 2201 evenly distributed circumferentially move upward to draw the gas in the airbag back to the fixed part of the several telescopic rods 2201 evenly distributed circumferentially. As the airbag is retracted, the material falls onto the material transport plate 2302. As the annular blade 20 continues to move upward and opens the blockage of the several ventilation slots 2203 evenly distributed circumferentially, the several telescopic rods 2201 evenly distributed circumferentially draw external gas into the fixed part, and repeat the above action as the second transmission shaft 10 rotates.

[0035] Embodiment 3: Based on embodiment 2, Figure 1-Figure 13 As shown, an extrusion process for catalyst production, using an anti-sticking extrusion device for catalyst production, includes the following steps: S1: Powder required for production is put into the discharge barrel (701) at one time, and the telescopic part of the spring telescopic part (3) moves according to the weight of the powder, and changes the shielding area of ​​the shielding part (2105) on the jet outlet of the jetting part (2004); S2: Start the motor and fill the second transmission shaft 10 with gas, the output shaft of the motor drives the rotating frame 8 to rotate, so that the jetting member 2004 jets the powder intermittently; S3: The rotating frame 8 drives the pressing roller 9 to rotate, and squeezes the powder into a plurality of forming holes of the first discharging frame 7 to form the material; S4: The annular blade 20 moves intermittently to cut the material and intermittently seal the forming hole, so that the annular blade 20 drives the telescopic part of the telescopic rod 2201 to move, blows out the gas in the telescopic rod 2201, and makes the annular blade 20 cover the ventilation slot 2203 to deploy the airbag; S5: the unloading member 2305 pushes the material onto the second baffle 2306 for collection; S6: When the production is completed, wait until the powder in the first discharging rack 7 is used up, the telescopic part of the spring telescopic part 3 moves, so that the flow area of ​​the jet port of the jet part 2004 is restored to the initial size, the motor is turned off and the gas filling into the second transmission shaft 10 is stopped.
