Description

Technical Field

[0001] The invention relates to the technical field of molecular sieve manufacturing, in particular to a molecular sieve raw material powder batching device. Background Art

[0002] Molecular sieve is a solid material with a regular pore structure. It is formed by silicon atoms or aluminum atoms combined with oxygen atoms by coordination bonds. The pore size and shape of the molecular sieve are mainly composed of its skeleton, while the pore structure is determined by the two-dimensional network formed by silicon atoms or aluminum atoms on the surface of the molecular sieve. This unique pore structure gives the molecular sieve high selectivity and adsorption performance, and can effectively separate and purify molecules in various gases, liquids and solid mixtures. As a material with a unique pore structure and excellent performance, molecular sieve has broad application prospects in various fields.

[0003] The manufacture of molecular sieves requires the selection of appropriate raw materials such as silicon source, aluminum source, template and catalyst, and the drying, crushing and screening of the raw materials to obtain powdered raw materials that meet the requirements. The powdered raw materials are then mixed with a solvent to form a uniform solution. The solution is then subjected to sol preparation, crystal growth, washing, drying and post-treatment processes to form a solid material with uniform pore size. When the raw powder ingredients are mixed into a solution, the mixing process of the powdered raw materials with the solvent and catalyst takes a long time. During the mixing process through the mixer, the powdered material moves in the same direction as the solvent, and the powdered material dissolves into the solvent more slowly. In addition, the powdered material often settles at the bottom, reducing the dissolution efficiency. Summary of the invention

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] Combined with Figure 1 and attached Figure 2As shown, a molecular sieve raw material powder batching device includes a batching bin 2 and a feeding platform 1, the feeding platform 1 is connected to the top of the batching bin 2, a plurality of feeding pipes 15 connected to the batching bin 2 are arranged on the feeding platform 1, a mixing mechanism 3 for uniformly mixing the materials is arranged in the batching bin 2, the mixing mechanism 3 includes a driving mechanism 4 and a plurality of stirring columns 5, the driving mechanism 4 drives the stirring columns 5 to rotate so that the materials are uniformly mixed, a support frame 21 is arranged on the outer side of the bottom of the batching bin 2, and a discharge pipe 22 is arranged at the bottom of the batching bin 2;

[0032] Combined with Figure 3 , Attachment Figure 6 and attached Figure 7 As shown, the driving mechanism 4 includes a motor 41, a moving gear 42 and a fixed gear 43. The output end of the motor 41 is provided with a driving gear 411 meshing with the moving gear 42. A driving disk 421 is provided at the bottom of the moving gear 42. The fixed gear 43 is connected to the feeding table 1 through a connecting disk 431 at the top. The connecting shaft between the moving gear 42 and the driving disk 421 passes through the central through hole of the fixed gear 43. The fixed gear 43 is rotatably arranged on the driving disk 421. The stirring column 5 includes a transmission gear 51 and a rotating column 52. The top of the rotating column 52 passes through the side through hole of the driving disk 421 and is connected to the transmission gear 51. The transmission gear 51 meshes with the fixed gear 43. A plurality of stirring paddle mechanisms 53 are provided on the outside of the rotating column 52. A flipping paddle 521 is provided on the outside of the bottom of the rotating column 52.

[0033] Working principle of driving mechanism 4: motor 41 drives driving gear 411 to rotate, and through the meshing transmission of driving gear 411 and moving gear 42, the moving gear 42 is driven to rotate, so that the driving disk 421 connected to the shaft rotates synchronously, and multiple stirring columns 5 rotate synchronously with the driving disk 421. The fixed gear 43 is connected to the feeding platform 1 through the connecting disk 431. The fixed gear 43 does not rotate. Through the meshing transmission of transmission gear 51 and fixed gear 43, the stirring column 5 drives the rotating column 52 to rotate while it revolves through the transmission gear 51, so that the rotation speed of the stirring paddle mechanism 53 and the flipping paddle 521 is increased, and the material mixing speed is accelerated. The stirring paddle mechanism 53 is used to mix the materials in the batching bin 2, and the flipping paddle 521 is used to flip the deposited materials at the bottom of the batching bin 2 to the upper layer.

[0034] Combined with Figure 8 , Attachment Fig. 9 and attached Fig.12 As shown, the stirring paddle mechanism 53 includes a stirring paddle 531 and a transmission ring 534. A turntable 532 is provided on the inner side of the stirring paddle 531. The turntable 532 is rotatably arranged in a side through hole of a rotating column 52. An eccentric column 533 is provided on the inner side of the turntable 532. A connecting rod 535 is hingedly provided on the outer side of the transmission ring 534. The connecting rod 535 is hinged to the eccentric column 533. An adjusting column 54 that can move up and down is provided in the rotating column 52. The transmission ring 534 is connected to the rotating column 52. The stirring paddles 531 of adjacent stirring paddle mechanisms 53 are staggered.

[0035] Working principle of the stirring paddle mechanism 53: the transmission ring 534 moves up and down with the adjustment column 54. When the transmission ring 534 moves, the connecting rod 535 and the eccentric column 533 cooperate to drive the turntable 532 to rotate, so as to adjust the angle of the stirring paddle 531. In the initial state, the stirring paddle 531 is oblique, and the oblique stirring paddles 531 of multiple stirring paddle mechanisms 53 are combined to form a spiral shape. During the adjustment process, the stirring paddle 531 rotates in the opposite direction of the oblique direction. The spiral structure formed by the combination of multiple stirring paddles 531 is opposite to the spiral structure in the initial state, thereby making the stirring flow direction opposite. Multiple changes in the stirring direction can make the materials mixed evenly.

[0036] Combined with Figure 5 , Attachment Fig. 9 , Attachment Fig.10 and attached Fig.11 As shown, a transmission slide 1 541 and a transmission slide 2 542 are respectively provided at the upper and lower ends of the adjusting column 54, a transmission slide 1 523 and a transmission slide 2 524 which are slidably matched with the transmission slide 1 541 and the transmission slide 2 542 are respectively provided on the inner side of the top and the inner side of the bottom of the rotating column 52, a positioning slider 55 is rotatably provided at the top of the adjusting column 54 through the central through hole of the transmission gear 51, a positioning slide 17 which is matched with the positioning slider 55 is provided at the bottom of the feeding table 1, and the depth of the positioning slide 17 changes with the position, a connecting column 543 is provided at the bottom of the adjusting column 54, the connecting column 543 passes through the through hole on the inner baffle 525 of the rotating column 52 and is provided with a bottom plate 545, a spring 544 is provided on the outer side of the connecting column 543, both ends of the spring 544 are connected with the baffle 525 and the bottom plate 545, and a sealing cover 522 is provided at the through hole at the bottom of the rotating column 52.

[0037] Working principle of the adjusting column 54: through the cooperation of the transmission slide 1 541 and the transmission slide 2 542 with the transmission slide 1 523 and the transmission slide 2 524, the adjusting column 54 can rotate with the rotating column 52 to ensure the stability of the stirring paddle mechanism 53. In the process of the adjusting column 54 revolving with the rotating column 52, the positioning slider 55 slides along the positioning slide 17, and the depth of the positioning slide 17 changes. In the process of the positioning slide 17 from shallow to deep, the positioning slider 55 drives the adjusting column 54 to move upward, and vice versa, it will drive the adjusting column 54 to move downward, realizing the up and down movement of the adjusting column 54. The spring 544 applies force to the adjusting column 54 to ensure that the positioning slider 55 does not separate from the positioning slide 17.

[0038] Combined with Figure 3 , Attachment Fig.13 and attached Fig.14As shown, a discharging mechanism 6 is provided at the bottom of the batching bin 2, and the discharging mechanism 6 includes a discharging base 61, a cylinder 62 and a floating platform 63. The discharging base 61 is connected to the through hole at the bottom of the batching bin 2, and a discharging port 612 connected to the discharging pipe 22 is provided at the bottom, and a pressing platform 611 flush with the inner side of the bottom of the batching bin 2 is provided at the top. The bottom side of the floating platform 63 contacts and cooperates with the top of the pressing platform 611, and a discharging ring platform 631 is provided at the bottom of the floating platform 63. A plurality of discharging holes 632 are provided on the discharging ring platform 631. A receiving platform 613 is provided on the inner side of the discharging base 61, and a discharging hole 614 is provided below the discharging ring platform 631. The cylinder 62 is fixed on the receiving platform 613, and the output end of the cylinder 62 is connected to the floating platform 63. A retaining ring 633 slidingly matched with the through hole at the top of the floating platform 63 is provided at the outside of the cylinder 62 at the bottom of the floating platform 63, and a clamping spring 634 is provided on the outside of the retaining ring 633.

[0039] Working principle of the discharge mechanism 6: in the initial state, the bottom side of the floating platform 63 is tightly attached to the pressing platform 611, and the bottom of the discharge ring platform 631 is tightly attached to the receiving platform 613 at the discharge hole 1 614, realizing the double blocking of the discharge hole 1 614 and the discharge hole 2 632 to ensure that there will be no leakage. After the material mixing is completed, the cylinder 62 pushes the floating platform 63 to move up, so that the discharge hole 2 632 is connected with the batching bin 2, and the discharge hole 1 614 is opened at the same time, and the material flows into the discharge pipe 22 along the discharge hole 2 632 and the discharge hole 1 614 to discharge the material. The baffle ring 633 prevents the material from flowing into the cylinder 62 position. After the discharge is completed, the compression spring 634 makes the floating platform 63 and the discharge ring platform 631 close to the pressing platform 611 and the receiving platform 613 again to complete the closure.

[0040] Combined with Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, the feeding platform 1 includes a cover plate 11, which is connected to the top of the batching bin 2. A bottom guard 13 for protecting the driving mechanism 4 is provided at the bottom of the cover plate 11, and a bracket 18 for fixing the motor 41 and a top guard 12 for protecting the motor are provided at the top. A feeding trough 14 is provided on the feeding platform 1, and a feeding port 141 connected to the batching bin 2 is provided at the bottom of the feeding trough 14. A feeding pipe 15 is connected to the through hole at the top of the feeding trough 14, and a feeding port 16 connected to the batching bin 2 is provided on the feeding platform 1.

[0041] Working principle of the feeding station 1: the material enters the feeding trough 14 through the feeding pipe 15, is buffered by the feeding trough 14, and then dispersed into the batching bin 2 through multiple feeding ports 141. The additionally designed feeding port 16 can add materials outside the process or powdered materials to the material mixing. The bottom guard 13 rotates with the stirring column 5 to prevent the material from entering the gear meshing area. The top guard 12 is used to protect the motor 41.

[0042] In the specific implementation of the present invention, multiple materials are quantitatively fed into the batching bin 2 through the feed pipe 15 or the feeding port 16, and the multiple stirring columns 5 are driven by the driving mechanism 4 to realize rotation during the revolution. The stirring paddle mechanism 53 on the stirring column 5 mixes the materials. The stirring paddle 531 is adjusted by adjusting the column 54 to move up and down during the revolution to accelerate the mixing of the materials. The flipping paddle 521 at the bottom of the stirring column 5 makes the deposited material float. After the mixing is completed, the double channels of the discharge mechanism 6 are opened to discharge the materials into the discharge pipe 22.

[0043] According to the processing requirements, conventional structures such as heaters, sensors, sampling ports, etc. can be added to the batching bin 2 to convert it into a catalytic bin. The material conveying device connected to the feed pipe 15 is required to realize the quantitative conveying function.

[0044] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
