Description

Technical Field

[0001] The invention relates to the technical field of catalyst powder granulation, and in particular to a granulation device applied to catalyst. Background Art

[0002] A granulator is a molding machine that can make materials into specific shapes. In order to ensure that the hydrogenation reduction catalyst can be recovered and hydrogenated for reuse after use, it needs to have the mechanical strength to withstand the extrusion of the reaction equipment without breaking, so a granulator is needed for its preparation.

[0003] The catalyst granulation equipment in the prior art usually utilizes hydraulic or screw conveying equipment to extrude the catalyst into strips from the discharge port, and uses a blade to cut the catalyst into pellets. For example, a catalyst granulation device for coal chemical conversion reaction disclosed in Publication (Announcement) No.: CN116099502A has a cutting device that can cut the extruded catalyst to form catalyst particles, thereby completing the pelletizing work. When in use, the operator connects the servo motor to the power supply and turns on the servo motor switch. The servo motor drives the rotating column to rotate, so that the cutting blade cuts the catalyst strips discharged from the lower surface of the molding device to achieve the effect of making the catalyst particles of uniform size.

[0004] As disclosed in the publication (announcement) No. CN116510619A, after all the molds are installed into the rollers, the motor is turned on, and the rollers are driven by the transmission assembly to rotate, and the mixed carrier material is put into the feed hopper. The carrier material is squeezed into two rollers rotating in opposite directions under the action of gravity. Each mold cavity of the molds on the two rollers is a hemispherical pit, and the mold cavities of the molds on the two rollers are synchronously meshed into a spherical cavity during the rotation of the rollers. The friction force generated by the rotation of the two rollers squeezes the carrier material into the spherical cavity. As the spherical cavity is rotated until the two rollers are completely disengaged, the spherical carrier in the spherical cavity falls into the discharge hopper under the action of gravity.

[0005] In the above technical solutions, the extruded strips are either cut or the catalyst raw materials are molded using a spherical mold of a rotating roller. In addition, due to insufficient cooling time or insufficient retention time of the raw materials in the mold, the cutting impact of the blade causes deformation and insufficient strength after molding, thus affecting the quality of the particles after molding.

[0006] In view of the deficiencies in the prior art, the present invention provides a granulation device for catalysts with high molding quality, aiming to alleviate the above problems at least to a certain extent.

The movement of two laterally adjacent support plates approaching each other can move the molding plates thereon. The movement of two laterally adjacent molding plates relative to each other can squeeze the powder raw material put between them. Since the molding plates are inclined at a preset angle, when the molding plates move to extrude the powder, the bottoms of the two molding plates will first contact the raw material. Until the fitting surfaces of the two forming plates are completely released, it can ensure that there is enough raw material in the forming port, and the raw material outside the forming port can be discharged, so as to avoid the problem that the fitting surfaces of the two forming plates cannot be fully contacted due to too much raw material.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] refer to Figure 1-Figure 8 , a granulation device for catalyst, comprising:

[0046] A base 100, with a hopper 101 disposed on the top of the base 100;

[0047] A molding cavity 102 is provided at the bottom of the hopper 101. A plurality of molding plates 103 are provided in the molding cavity 102. A molding opening 104 is provided on the molding plates 103.

[0048] The support plate 105 is disposed on one side of the forming plate 103. The forming plate 103 is rotatably connected to the support plate 105. The forming plate 103 is tilted at a preset angle on the support plate 105.

[0049] A feed inlet 106 and a blanking inlet 107, wherein the feed inlet 106 is provided at the bottom of the hopper 101 and communicates with the molding cavity 102, and the blanking inlet 107 is provided at the bottom of the molding cavity 102;

[0050] The box body 108 is disposed between the base 100 and the molding cavity 102 and is used to contain the molded particles falling from the drop opening 107. Two material shifting forks 109 are disposed in the box body 108;

[0051] A driving shaft 110 is disposed at one side of the molding cavity 102, and the driving shaft 110 can move the position of the supporting plate 105 when rotating;

[0052] The driving component is disposed between the molding cavity 102 and the driving shaft 110, and is used to rotate the driving shaft 110. The driving shaft 110 can sequentially move the plurality of support plates 105 from bottom to top during the first rotation, and two laterally adjacent support plates 105 move closer to each other. The driving shaft 110 can sequentially move the plurality of support plates 105 from bottom to top during the second rotation, and two adjacent support plates 105 move away from each other.

[0053] The driving shaft 110 can open and close the feed port 106 when rotating one circle. When the feed port 106 is in an open state, the blanking port 107 is in a closed state. When the feed port 106 is in a closed state, the blanking port 107 is in an open state.

[0054] The driving shaft 110 can rotate the two material shifting forks 109 when rotating one circle, and the material shifting forks 109 can be reset after rotating to a preset angle;

[0055] By setting the hopper 101, when in use, the operator can put the catalyst powder raw material into the hopper 101. In the initial state, the feed port 106 at the bottom of the hopper 101 is in an open state, and the discharge port 107 is in a closed state. The longitudinally adjacent forming plates 103 contact each other to form a discharge channel, and the raw material can fall into the discharge channel. The forming port 104 on the forming plate 103 can contact the raw material. During granulation, the operator can use the driving component to rotate the driving shaft 110. The rotation of the driving shaft 110 can move multiple support plates 105 from bottom to top in sequence during the first rotation. The movement of two laterally adjacent support plates 105 approaching each other can move the forming plates 103 thereon. The two laterally adjacent forming plates 103 The mutual movement can squeeze the powder raw materials put between the two, and because the molding plates 103 are inclined at a preset angle, when the molding plates 103 move to squeeze the powder, the bottoms of the two molding plates 103 will first contact the raw materials until the fitting surfaces of the two molding plates 103 are completely released, which can ensure that there is enough raw material in the molding port 104, and the raw material outside the molding port 104 can be discharged, avoiding the problem that the fitting surfaces of the two molding plates 103 cannot be completely contacted due to too much raw material. After the driving shaft 110 rotates for the first round to allow all the molding plates 103 to move, the feed port 106 can be closed, and the drop port 107 is opened at this time, wherein the powder raw materials squeezed out by the molding plates 103 in the molding cavity 102 can fall from the drop port 107 to In the box body 108, when the driving shaft 110 rotates for the second circle, the multiple support plates 105 can move the positions of the support plates 105 from bottom to top in sequence, and the support plates 105 and the forming plates 103 move away from each other to reset. At this time, the spherical particle catalyst formed in the forming port 104 can fall into the box body 108 due to gravity. At this time, there is some powder raw material in the box body 108, and the powder raw material can buffer the falling particle raw material, which can effectively reduce the probability of fragmentation due to the free fall of the particles and improve the yield. At the same time, after the driving shaft 110 rotates for the first circle to shape the powder raw material, the driving shaft 110 rotates for the second circle to release the spherical forming catalyst. In this process, the bottom forming plate 103 will be The movement starts, that is, the bottom molding plate 103 is the first to mold the powder, and the multiple molding plates 103 above it mold the powder in turn. There will be a period of molding time, and the driving shaft 110 rotates the second circle to separate the multiple molding plates 103 from bottom to top in turn, so that the molding plates 103 have enough time to press and mold the powder and have enough time to cool. Compared with the cutting or roller pressing in the prior art, the raw material does not stay in the mold for enough time, and it is not possible to give the raw material enough molding time, resulting in insufficient strength after molding. The provided molding plate 103 and molding port 104 can ensure the shape of the raw material after molding, and will not be deformed due to the impact cutting of the blade. Further,The material shifting fork 109 can rotate to a preset angle when the driving shaft 110 rotates to open the feed port 106 and close the drop port 107. The rotation of the material shifting fork 109 can rotate and shift the formed granule balls that fall at the center of the box body 108 to the two sides inside the box body 108, so as to facilitate the subsequent formed granule balls to fall on the powder pile at the center of the box body 108, and avoid the problem that the raw materials cannot be piled up to buffer the free-falling granule balls due to excessive accumulation of granule balls under the drop port 107. Compared with the granulation equipment in the prior art, the present application can solve the problem of insufficient strength after molding caused by insufficient retention time of raw materials in the mold due to roller granulation, and the problem of deformation caused by insufficient cooling time of formed strips due to blade cutting impact due to cutting granulation, and can achieve the effect of improving molding quality.

One end of the first reciprocating screw 202 extends to the outside of the molding cavity 102 and is connected to a second gear 203 adapted to the first gear 200.

[0057] By setting the first gear 200, since the horizontal heights of each support plate 105 are different, when the first gear 200 rotates by a preset angle, it will mesh with the second gear 203 at the bottom. As the first gear 200 continues to rotate, the second gear 203 at the bottom can be rotated, so that the support plate 105 can be moved through the first reciprocating screw rod 202 and the screw tube 201. After the driving shaft 110 rotates the first gear 200 for one circle, the purpose of making multiple support plates 105 move from bottom to top can be achieved. When the second gear 203 is rotated by a preset angle to move the first reciprocating screw 202 to the position of the screw tube 201, the first gear 200 leaves the second gear 203, which is the limit position of the movement of the screw tube 201. When the second gear 203 rotates again, the screw tube 201 can generate a reset movement through the first reciprocating screw 202, thereby achieving the purpose of allowing the support plates 105 to move closer to each other when the drive shaft 110 rotates one circle, and allowing the support plates 105 to move away from each other when the drive shaft 110 rotates a second circle.

[0059] By setting the third gear 304, after the first gear 200 rotates to allow all the support plates 105 to be displaced so that the forming plate 103 can press the raw material, the first gear 200 can be meshed with the third gear 304 after being disengaged from the top second gear 203, and the third gear 304 and the second reciprocating screw 303 can be rotated when the first gear 200 continues to rotate. The rotation of the second reciprocating screw 303 can move the first baffle 301 through the force of the thread, and the movement of the two first baffles 301 located in the two first connecting ports 300 approaching each other can achieve the closure of the feed port 106, thereby achieving the purpose of opening or closing the feed port 106 when the drive shaft 110 rotates to a preset angle.
