Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, in particular to a production dust removal system for granular catalysts. Background Art

[0002] In a chemical reaction, a substance that can change the chemical reaction rate of the reactants without changing the chemical equilibrium, and whose own quality and chemical properties do not change before and after the chemical reaction, is called a catalyst. Solid catalysts are also called catalysts. According to statistics, catalysts are used in more than 90% of industrial processes. In order to make the catalyst of better quality and higher purity, it is very necessary to remove the dust of the catalyst material.

[0003] For example, the patent with publication number CN222753778U, entitled "A Dust Removal Device for Catalyst Production", with an authorization announcement date of April 15, 2025, comprises a box body with a feed inlet and a discharge outlet provided on the box body, and is characterized in that: a plurality of filter plates distributed up and down and inclined are fixedly installed in the box body, the inclination directions of two adjacent filter plates are opposite, a first inclined plate is fixedly provided below each filter plate, and the inclination direction of the first inclined plate is opposite to that of the corresponding filter plate, a plurality of first through-grooves are provided on the box body corresponding to the first through-grooves, a plurality of filter boxes are connected and installed on the box body corresponding to the first through-grooves, and suction fans are respectively connected and installed on the filter boxes, a second inclined plate is fixedly installed on the lower side of the inner side of the box body, an end of the second inclined plate near the discharge outlet is lower than an end away from the discharge outlet, and an end of the second inclined plate near the discharge outlet is fixedly connected to the lower side of the inner wall of the discharge outlet; the structure is simple and the design is ingenious, and the plurality of inclined filter plates are provided to extend the travel of dust in the box body, so that dust removal is more complete, which can meet market demand and is suitable for promotion.

[0004] The shortcoming of the existing technology is that, since the granular catalyst raw materials are physically dusted, shaking is usually used to separate the dust particles on their surface from the screened-out catalyst raw materials. However, the catalyst structure may be damaged during the production process, and the surface of the raw materials may be deformed or roughened, which aggravates the retention of dust. As a result, the surface of the shaken Qiongli granular catalyst raw materials still adsorbs dust, resulting in uneven dust cleaning effects and affecting the overall dust removal effect of the granular catalyst raw materials.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-10A dust removal system for the production of granular catalysts includes: a box body 1, a hopper 2, and a connecting tube 4; an elastic screen 41, the top of the elastic screen 41 is fixedly connected to the opening of the connecting tube 4, and the end of the elastic screen 41 away from the connecting tube 4 is fixedly connected to a discharge pipe 42, and the elastic screen 41 is used to receive the catalytic raw material and realize the collision of the catalytic raw material with the catalytic raw material to separate the impurities adsorbed by the catalytic raw material itself; a dust removal component 5 is also included, and the dust removal component 5 includes a dust removal bin 51, and the dust removal bin 51 is connected to the elastic screen 41. The discharge end is connected, and a filter plate 52 is provided in the dust removal bin 51. The filter plate 52 divides the dust removal bin 51 into left and right bins. A conductive member 8 is provided in the left bin. The bottom end of the conductive member 8 is fixedly connected to the elastic screen 41, and the top end of the conductive member 8 is fixedly connected to the hopper 2. The end of the conductive member 8 close to the elastic screen 41 is fixedly connected to the filter plate 52. The vibration generated by the elastic screen 41 is transmitted to the hopper 2 and the filter plate 52 through the conductive member 8, so that the dust on the surface of the filter plate 52 is removed by vibration and the clogging of the discharge end of the hopper 2 is avoided.

[0040] Specifically, the box body 1 is a rectangular frame structure, and a hopper 2 fixedly connected to the box body 1 is provided at its top. The granular catalyst raw material is fed into the hopper 2. The hopper 2 includes a guide plate 21 and a rubber plate 22 fixedly connected to the guide plate 21. The hopper 2 and the rubber plate 22 are fixedly connected to the connecting cylinder 4. The hopper 2 and the fixed driving assembly 3 form an annular channel, so that the granular catalyst raw material falls along the annular channel formed by the hopper 2 along the connecting cylinder 4 onto the elastic screen 41. The elastic screen 41 is provided just below the annular channel. When the granular catalyst raw material falls, it contacts the bottom of the connecting cylinder 4. After the fixed elastic screen 41 collides, the dust adsorbed on the surface of the granular catalyst raw material is separated during the collision process (the dust adsorbed on the surface of the granular catalyst raw material is mainly: impurities such as dust or particulate matter accumulated on the catalyst surface. Under conditions such as high temperature sintering, mechanical wear or humidity changes, the catalyst structure may be damaged, resulting in deformation or roughening of the raw material surface, which aggravates the retention of dust). The granular catalyst raw material after the collision is discharged from the discharge pipe 42 fixedly connected to the elastic screen 41. The elastic screen 41 is tilted from the outside to the middle to gather the structure, so that the granular catalyst raw material can be discharged. The dust separated by the collision of the catalyst particles is discharged from the discharge pipe 42 and is sucked into the dust removal bin 51 by the air pump 7 fixedly connected to the outside of the box body 1. A plurality of air pumps 7 are distributed in a ring around the box body 1 and are connected to the dust removal bin 51 through a pipe. The filter plate 52 located in the dust removal bin 51 divides the dust removal bin 51 into left and right bins. The left bin is connected to the elastic screen 41, so that the dust separated by the collision of the catalyst particles is adsorbed on the surface of the filter plate 52 in the left bin under the action of the air pump 7. The vibration generated by the collision of the elastic screen 41 and the catalyst particles is transmitted to the filter plate 52 through the conductive member 8. The dust adsorbed on the surface of the filter plate 52 at one end of the left bin falls into the collecting box 59 at the bottom end of the filter plate 52 during the vibration process for collection. The collecting box 59 is connected to the dust removal bin 51 in a threaded connection manner. The mobile box 59 is a detachable structure. The hopper 2 connected to the top of the conductive member 8 is vibrated. On the one hand, the phenomenon of clogging of the granular catalyst raw material at the discharge end of the hopper 2 is reduced. On the other hand, the dust that falls off due to stirring in the hopper 2 is discharged from the hopper during the shaking, preventing the fallen dust from being adsorbed on the surface of the granular catalyst raw material again.

[0041] The conducting member 8 includes a connecting rod 81, which is provided with a support rod 85. One end of the support rod 85 is fixedly connected to a connecting seat 86, and the connecting seat 86 is adapted to and fixedly connected to the bottom surface of the elastic screen 41; the top of the connecting rod 81 is fixedly connected to a spring plate 82, and the end of the connecting rod 81 close to the spring plate 82 is provided with a limiting groove 83, and a limiting rod 24 is provided in the limiting groove 83. The two ends of the limiting rod 24 are symmetrically fixedly connected to triangular blocks 23, and the triangular blocks 23 are fixed to the hopper 2; the end of the connecting rod 81 close to the filter plate 52 is fixedly connected to a support plate 84, the top of the support plate 84 is fixedly connected to a spring member 54, the top of the spring member 54 is fixedly connected to a fixing bar 53, and the fixing bar 53 is fixedly connected to the filter plate 52;

[0042] Specifically, the conducting member 8 is distributed on the circumference of the connecting cylinder 4 by multiple groups of rings. The connecting rod 81 in the conducting member 8 passes through the dust removal bin 51. The movable tube at the bottom end of the connecting rod 81 is connected to a support rod 85. The support rod 85 is movably connected to the connecting seat 86. The connecting seat 86 is fixed on the bottom surface of the elastic screen 41. When the granular catalyst raw material collides with the elastic screen 41, the vibration generated is transmitted to the connecting rod 81. The connecting rod 81 is connected to the rubber plate 22 through the spring plate 82. The rubber plate 22 is arranged at the bending part of the hopper 2 to discharge the material, so as to reduce the discharge of the material by utilizing the vibration generated by the collision of the granular catalyst raw material and the elastic screen 41. The outlet end is blocked. On the other hand, the dust that falls off due to stirring of the granular catalyst raw material in the hopper 2 is discharged along the inner wall of the hopper 2 during vibration, thereby preventing the fallen dust from being adsorbed on the surface of the granular catalyst raw material again. Secondly, the support plate 84 is fixed to the spring member 54. The fixing bar 53 connected to the spring member 54 (a spring in the prior art) is fixed to the filter plate 52. The spring member 54 transmits the vibration transmitted by the support plate 84 to the fixing bar 53, so that the filter plate 52 fixedly connected to the fixing bar 53 vibrates the dust adsorbed on the surface through the transmitted vibration force, thereby improving the efficiency of dust shedding on the surface of the filter plate 52.

[0043] A driving assembly 3 is provided in the hopper 2, and the driving assembly 3 is connected to the linkage assembly 6, and the linkage assembly 6 is connected to the connecting rod 58. The connecting rod 58 drives the linkage assembly 6 to move the dust particles adsorbed on the surface of the filter plate 52 through the driving assembly 3, and the dust particles are removed and collected; the bottom end of the connecting rod 58 passes through the dust removal bin 51 and extends to the right bin, and the bottom end of the connecting rod 58 is fixedly connected to a fixing seat 57, and one end of the two fixing seats 57 is fixedly connected to a baffle 55, and both ends of the baffle 55 are fixedly connected to an air bag 56, and the air bag 56 is in contact with the surface of the filter plate 52; the driving assembly 3 includes a deflector 31, and the deflector 31 and the hopper 2 form an annular discharge channel, and the annular discharge channel is arranged directly above the elastic screen 41; the deflector 3 1 is fixedly connected to a drive motor 32, which passes through the deflector 31 and is provided with a motor shaft 33. Agitating rods 34 are symmetrically provided at both ends of the motor shaft 33. The end of the agitating rod 34 away from the motor shaft 33 is fixedly connected to a gear ring 35; the linkage assembly 6 includes a bracket 61, and the bracket 61 is fixedly connected to the hopper 2. A transmission shaft 62 is rotatably provided at the bottom end of the bracket 61. A linkage shaft 63 is meshed with one end of the transmission shaft 62, and the top end of the linkage shaft 63 is meshed with the gear ring; a connecting arm 65 is fixedly connected to the end of the transmission shaft 62 away from the linkage shaft 63. One end of the connecting arm 65 is fixedly connected to an eccentric shaft 64. A linkage frame 66 is sleeved on one end of the eccentric shaft 64, and the linkage frame 66 is fixed to the connecting rod 58;

[0044] Specifically, the driving motor 32 in the driving assembly 3 drives the stirring rod 34 and the gear ring 35 to rotate, and the fixing frame 321 fixed to the outside of the driving motor 32 fixes it to the deflector 31, and the bottom end array of the deflector 31 is fixedly fixed with a pillar 311, and the pillar 311 is fixedly connected to the connecting cylinder 4. The stirring rod 34 is used to stir the granular catalyst raw materials located in the hopper 2, so that the granular catalyst raw materials rub against each other during the feeding process, thereby improving the collision and separation effect of the granular catalyst raw materials, and the connecting shaft 63 engaged with the gear ring rotates (the connecting shafts 63 are symmetrically distributed at both ends of the gear ring, both engage with the gear ring, and the two connecting shafts 63 rotate in the same direction), and the connecting shaft 63 drives the transmission shaft 62 to rotate, and the transmission shaft 62 is fixedly connected to the eccentric shaft 64 through the connecting arm 65 along the transmission shaft 62 The axis rotates, so that the eccentric shaft 64 drives the sleeved linkage frame 66 and the connecting rod 58 to move back and forth along the bracket 61, so that the connecting rod 58 drives the baffle 55 located in the right bin of the dust removal bin 51 to move back and forth in a directional manner. The air bag 56 provided at one end of the baffle 55 near the filter plate 52 fits the surface of the filter plate 52. When the baffle 55 cooperates with the filter plate 52 blocked by the air bag 56, the position of the filter plate 52 in the left bin has no adsorption force, so that the dust particles adsorbed on the filter plate 52 are separated downward with the vibration. The two baffles 55 symmetrically distributed at one end of the filter plate 52 form a replacement state during the reciprocating motion, so that the dust on the surface of the filter plate 52 is separated in stages and introduced into the collection box 59, so that the dust particles are collected with minimal floating, thereby improving the efficiency of dust collection.

[0045] Working principle: the granular catalyst raw materials are fed into the hopper 2, and the granular catalyst raw materials fall onto the elastic screen 41 along the annular discharge channel formed by the guide cover 31 and the hopper 2. When the granular catalyst raw materials fall, they collide with the elastic screen 41 fixedly connected to the bottom end of the connecting tube 4. The dust adsorbed on the surface of the granular catalyst raw materials or the dust adsorbed on the rough surface caused by deformation is separated during the collision process. The granular catalyst raw materials after the collision are discharged from the discharge pipe 42 fixedly connected to the elastic screen 41. The dust separated by the collision of the granular catalyst raw materials is sucked into the dust removal bin 51 through the air pump 7 fixedly connected to the outside of the box body 1. There are multiple groups of air pumps 7 distributed in an annular manner on the periphery of the box body 1 and connected to the dust removal bin 51 through pipes; the left bin 51 is separated by the filter plate 52 in the dust removal bin 51, and the left bin It is connected to the elastic screen 41, so that the dust separated by the collision of the particle catalyst raw material is adsorbed on the surface of the filter plate 52 in the left bin under the action of the air pump 7, and the vibration generated by the collision of the elastic screen 41 and the particle catalyst raw material is transmitted to the filter plate 52 through the conductive member 8, so that the dust adsorbed on the surface of the filter plate 52 at one end of the left bin falls into the collection box 59 at the bottom end of the filter plate 52 for collection during the vibration process, wherein the connecting rod 81 in the conductive member 8 passes through the dust removal bin 51, and the movable tube at the bottom end of the connecting rod 81 is connected to a support rod 85, and the support rod 85 is movably connected to the connecting seat 86, and the connecting seat 86 is fixed on the bottom surface of the elastic screen 41. When the particle catalyst raw material collides with the elastic screen 41, the vibration generated is transmitted to the connecting rod 81, and the spring plate 82 fixed to the connecting rod 81 , and the rubber plate 22 connected to the spring plate 82, the rubber plate 22 is arranged at the bending part of the hopper 2 (rubber plate 22) where the material is discharged, and the vibration generated by the collision of the granular catalyst raw material and the elastic screen 41 is used to reduce the blockage of the discharge outlet end. On the other hand, the dust that falls off due to stirring of the granular catalyst raw material in the hopper 2 is discharged along the inner wall of the hopper 2 during the vibration, so as to prevent the fallen dust from being adsorbed on the surface of the granular catalyst raw material again. The support plate 84 is fixed with the spring member 54, and the fixing bar 53 connected to the spring member 54 (the spring in the prior art) is fixed on the filter plate 52. The spring member 54 transmits the vibration transmitted by the support plate 84 to the fixing bar 53, so that the filter plate 52 fixedly connected with the fixing bar 53 vibrates the dust adsorbed on the surface through the conducted vibration force, so In order to remove dust, a driving assembly 3 is provided in the hopper 2, and the driving assembly 3 drives the linkage assembly 6 to move to realize the removal of dust particles adsorbed on the surface of the filter plate 52, wherein the linkage shaft 63 engaged with the gear ring 35 rotates (the linkage shafts 63 are symmetrically distributed at both ends of the gear ring, both meshing with the gear ring 35, and the two linkage shafts 63 rotate in the same direction), the gear block at the bottom end of the linkage shaft 63 meshes with the gear ring 35, and the bevel gear at the bottom end of the coaxial transmission of the linkage shaft 63 meshes with the bevel gear fixed to the end of the transmission shaft 62, so that the linkage shaft 63 drives the transmission shaft 62 to rotate, and the eccentric shaft 64 fixedly connected to the transmission shaft 62 through the connecting arm 65 rotates along the axis of the transmission shaft 62, so that the eccentric shaft 64 drives the sleeved linkage frame 66 and the connecting rod 58 to directional reciprocate along the bracket 61.The connecting rod 58 drives the baffle 55 located in the right bin of the dust removal bin 51 to directional reciprocate. The air bag 56 provided at one end of the baffle 55 near the filter plate 52 is in contact with the surface of the filter plate 52. When the baffle 55 cooperates with the air bag 56 to block the filter plate 52, the position of the filter plate 52 in the left bin is blocked by the baffle 55, resulting in no adsorption force, so that the dust particles adsorbed on the filter plate 52 are separated downward by the conducted vibration. The two baffles 55 symmetrically distributed at one end of the filter plate 52 form a succession state during the reciprocating motion (the lower baffle covers the position of the upper baffle during the reciprocating motion stroke, and there is an overlapping covering area between the lower baffle and the upper baffle during the stroke, so that the dust can fall on the surface of the filter plate 52 in a succession state). The dust on the surface of the filter plate 52 is separated in stages and introduced into the collection box 59 for collection.
