Description

Technical Field

[0001] This utility model relates to the field of molecular sieve adsorbent production equipment, and specifically to a purification device for the production of molecular sieve adsorbents. Background Technology

[0002] Molecular sieves are artificially synthesized hydrated aluminosilicates or natural zeolites that have the function of screening molecules. Due to their strong adsorption capacity, high selectivity and high temperature resistance, they are widely used in organic chemical industry, petrochemical industry and waste gas purification.

[0003] Chinese utility model patent CN217094375U discloses a purification device for the production of molecular sieve adsorbents. The device includes a support frame, a box at the top of the support frame, a feed hopper extending to the top of the box's inner top wall, a guide plate between the left and right sides of the box's inner wall, a discharge pipe above the guide plate and extending to the right side of the box's inner wall, a filter screen extending through and above the discharge pipe on the left side of the box, a cylinder at the top of the filter screen, discharge pipes extending to the left and right sides of the cylinder's inner wall, respectively, and a control component extending into and through the filter screen at the top of the box. The control component is fixedly connected to the front and rear sides of the box's inner wall. A driven component extending through and to the right side of the box and fixedly connected to the bottom of the filter screen is located on the left side of the box, penetrating and engaging with the control component. However, in this kind of impurity removal device, the control component and the driven component are connected by gear meshing, and the cam rotation drives the filter screen and cylinder to vibrate. The gear structure is subjected to high stress and is easily damaged, resulting in poor stability of the entire transmission structure.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problems of existing impurity removal devices driven by gear structures, which are prone to damage and have poor stability, this utility model provides an impurity removal device for the production of molecular sieve adsorbents. The impurity removal device includes: a tank; a filtration structure including a slidably mounted limiting cylinder inside the tank and a filter screen mounted at the bottom of the limiting cylinder; a stirring structure including a rotatable rotating column mounted on the tank, a stirring rod mounted on the rotating column, and a drive motor for driving the rotating column; a vibration structure including an elliptical turntable mounted on the rotating column, a first connecting rod connected to the elliptical turntable, a second connecting rod hinged to the limiting cylinder, a third connecting rod connecting the first and second connecting rods, and a reset member mounted inside the tank and abutting below the filter screen; a hinge seat is arranged on the tank, and the third connecting rod is slidably hinged to the hinge seat, and the third connecting rod is hinged to the first and second connecting rods.

[0006] This invention discloses a purification device for producing molecular sieve adsorbents, comprising a tank, a filter structure, a stirring structure, and a vibration structure. The tank houses all the aforementioned structures. The filter structure includes a limiting cylinder and a filter screen; the limiting cylinder moves the filter screen, which filters the molecular sieve adsorbent. The stirring structure includes a rotating column, a stirring rod, and a drive motor. The drive motor rotates the stirring column, which in turn rotates the stirring rod, thereby stirring the molecular sieve adsorbent and facilitating its filtration. The vibration structure includes an elliptical turntable, a first connecting rod, a second connecting rod, a third connecting rod, and a reset component. The elliptical turntable drives the first connecting rod to extend and retract, and drives the second and third connecting rods to rotate, adjusting the tilt angles of the second and third connecting rods, thereby adjusting the straight-line distance between the first connecting rod and the limiting cylinder. When the tilt angles of the second and third connecting rods are large, the straight-line distance between them is small; conversely, when the tilt angles of the second and third connecting rods are large, the straight-line distance between them is large. The height of the first connecting rod remains constant. Therefore, when the elliptical turntable rotates, it can drive the limiting cylinder to vibrate up and down, facilitating the removal of impurities from the molecular sieve adsorbent. Simultaneously, the reset component is arranged below the filter screen, which can assist in lifting the limiting cylinder after it descends, balancing part of the weight of the filter structure and reducing the load on the drive motor. A single drive motor achieves both stirring and vibration functions, reducing cost and energy consumption. Through the above configuration, this utility model provides a purification device for producing molecular sieve adsorbents. By setting up an elliptical turntable, a first connecting rod, a second connecting rod, a third connecting rod, and a reset component, the linkage structure drives the filter structure to vibrate. Compared to a gear-driven structure, this device has a greater load-bearing capacity, better stability, and is more durable.

[0007] Furthermore, the turntable is elliptical in shape and has a guide groove; a guide post matching the guide groove is provided on the first connecting rod.

[0008] Furthermore, a limiting seat is provided on the tank body, and the limiting seat has a limiting hole that matches the first connecting rod.

[0009] Furthermore, a limiting post is provided on the hinge seat; a limiting groove matching the limiting post is provided on the third link along the length direction of the third link.

[0010] Furthermore, guide strips are arranged on the inner peripheral wall of the tank, and strip grooves matching the guide strips are formed on the outer peripheral wall of the limiting cylinder.

[0011] Furthermore, the reset component includes a telescopic column that abuts against the filter screen, a mounting box mounted on the tank body, and a compression spring disposed within the mounting box and connected to the telescopic column.

[0012] Furthermore, a limiting plate is provided on the telescopic column, the limiting plate being slidably arranged within the mounting box and abutting against the compression spring.

[0013] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0014] (1) By setting up an elliptical turntable, a first connecting rod, a second connecting rod, a third connecting rod, and a reset component, the connecting rod structure drives the filter structure to vibrate. Compared with the gear drive structure, it has a greater load-bearing capacity, better stability, and is more durable.

[0015] (2) The reset component is arranged below the filter screen, which can assist in lifting after the limit cylinder descends, balance part of the weight of the filter structure, and reduce the load on the drive motor. Attached Figure Description

[0025] See also Figure 1 and Figure 2The tank 1 is generally cylindrical.

The limiting cylinder 21 is generally cylindrical, and its diameter is slightly smaller than that of the tank 1. Further, guide strips 14 are arranged on the inner circumferential wall of the tank 1, and strip grooves matching the guide strips 14 are formed on the outer circumferential wall of the limiting cylinder 21 to define the sliding direction of the limiting cylinder 21. Specifically, the guide strips 14 extend in the vertical direction, and multiple strips are evenly and spaced along the circumference of the tank 1. For example, four guide strips 14 are provided. Correspondingly, four strip grooves are provided, each corresponding to one of the guide strips 14. Further, a discharge pipe is provided on the limiting cylinder 21 for discharging the molecular sieve adsorbent. Specifically, a clearance groove matching the discharge pipe is provided on the tank body 1, facilitating the discharge pipe's extension out of the tank body 1 and relative sliding with the tank body 1.

Furthermore, a guide plate is also provided inside the tank body 1, and a waste removal pipe is provided on the tank body 1; the guide plate is arranged at an angle. After the molecular sieve adsorbent enters the tank body 1, it falls onto the filter screen 22; the molecular sieve adsorbent flows on the filter screen 22 and is discharged from the discharge pipe; impurities pass through the filter screen 22, fall onto the guide plate, and are discharged from the waste removal pipe.

[0026] See also Figure 1 and Figure 2The stirring structure 3 includes a rotating column 31 rotatably mounted on the tank 1, a stirring rod 32 mounted on the rotating column 31, and a drive motor 33 driving the rotating column 31 to rotate. Specifically, a motor mount is installed on the tank 1, and the drive motor 33 is mounted on the motor mount. The motor shaft of the drive motor 33 is connected to the rotating column 31, driving the stirring rod 32 to stir the molecular sieve adsorbent introduced into the tank 1. In one or more embodiments, the vibration structure 4 includes an elliptical turntable 41 mounted on the rotating column 31, a first connecting rod 42 connected to the elliptical turntable 41, a second connecting rod 43 connected to the limiting cylinder 21, a third connecting rod 44 connecting the first connecting rod 42 and the second connecting rod 43, and a reset member 45 supporting the filter structure 2. Specifically, the elliptical turntable 41 is approximately elliptical in shape, and a guide groove is formed on the elliptical turntable 41, the guide groove being approximately elliptical in shape. A connecting lug is provided at one end of the first connecting rod 42 near the elliptical turntable 41, and the two connecting lugs are respectively located on the upper and lower sides of the elliptical turntable 41. A guide post 421 is provided between the two connecting ears, and the guide post 421 matches the guide groove. Further, a limiting seat 13 is provided on the tank body 1, and a limiting hole matching the first connecting rod 42 is opened on the limiting seat 13 to limit the sliding direction of the first connecting rod 42. When the rotating column 31 rotates, the elliptical turntable 41 rotates accordingly, thereby driving the first connecting rod 42 to move closer to or away from the rotating column 31. Further, the two ends of the third connecting rod 44 are respectively hinged to the first connecting rod 42 and the second connecting rod 43. For example, the hinged connection can be achieved through the matching of the hinge post and the hinge hole.

The limiting post 12 is arranged in the limiting groove 441, so that the third link 44 and the hinge seat 11 form a sliding hinge engagement, avoiding the first link 42 from tilting and interfering with the elliptical turntable 41 when the link moves.

[0027] See also Figure 1 and Figure 2In one or more embodiments, one end of the second connecting rod 43 is connected to the third connecting rod 44, and the other end is connected to the support on the limiting cylinder 21.

Specifically, the reset member 45 includes a telescopic column 451 abutting against the filter screen 22, a mounting box 452 installed on the tank body 1, and a compression spring 453 arranged within the mounting box 452. The mounting box 452 is generally cylindrical. When the limiting cylinder 21 and the filter screen 22 move downwards, the telescopic column 451 retracts into the mounting box 452, and the compression spring 453 is compressed; when the limiting cylinder 21 and the filter screen 22 move upwards, the compression spring 453 extends, and the telescopic column 451 extends out of the mounting box 452. Further, a limiting plate 454 is provided on the telescopic column 451, and the limiting plate 454 mates with the mounting box 452. The compression spring 453 is arranged between the limiting plate 454 and the bottom plate of the mounting box 452. When the elliptical turntable 41 rotates, and the first connecting rod 42 moves away from the rotating column 31, the third connecting rod 44 rotates around the limiting column 12 and moves downward. The upper end of the third connecting rod 44 moves away from the tank 1, and the lower end of the third connecting rod 44 moves closer to the tank 1. The upper end of the second connecting rod 43 moves closer to the tank 1. The second connecting rod 43 and the third connecting rod 44 change from an inclined state to a near-vertical state, thereby driving the limiting cylinder 21 to move downward. As the turntable continues to rotate, the first connecting rod 42 moves closer to the rotating column, the upper end of the third connecting rod 44 moves closer to the tank 1, and the lower end of the third connecting rod 44 moves away from the tank 1. The upper end of the second connecting rod 43 moves away from the tank 1, and the limiting cylinder 21 moves upward. The compression spring 453 assists the connecting rod structure in lifting the limiting cylinder 21 and the filter screen 22, balancing part of the weight of the limiting cylinder 21 and the filter screen 22, and reducing the load on the drive motor 33.
