Description

Technical Field

[0001] The invention relates to the technical field of molecular sieve preparation and processing equipment, and in particular to an environmentally friendly post-processing device for molecular sieve preparation. Background Art

[0002] Molecular sieve is a crystalline compound with a specific pore size distribution. Molecular sieve has a microporous structure and can adsorb molecules of different sizes. Its crystal pore size is generally between 0.3 and 0.8 nanometers. The pores are arranged in an orderly manner and are uniform in size, which allows the molecular sieve to separate molecules of similar molecular sizes. Molecular sieve crystals have strong adsorption capacity and selectivity, and can be used to selectively adsorb, separate, concentrate, and purify various molecules.

[0003] The production of molecular sieves is a complex and delicate process, which includes multiple key steps such as raw powder manufacturing, granulation, screening, drying, roasting and packaging. Among them, screening is a key link in the production of molecular sieves, and its main purpose is to classify the granulated products according to particle size. The design of the screening box and the screen inside it plays a decisive role in the screening effect. Through reasonable screening, it can ensure that the particle size distribution of the product meets the standard and improve the uniformity and stability of the product.

[0004] At present, there are the following technical problems in molecular sieve screening. First, clogging is prone to occur during the screening process, that is, the molecular sieve often gets stuck on the screen. Screen blockage not only affects the screening efficiency, but may also cause equipment performance degradation and even cause failures. Second, traditional screening equipment often uses a single drive structure, which not only limits the flexibility and adaptability of the equipment, but also easily causes wear and failure due to long-term operation, thereby shortening the service life of the equipment.

[0024] 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. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0026] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0027] Example 1 of the environmentally friendly post-treatment device for preparing the molecular sieve provided by the present invention:

[0028] like Figures 1 to 3 As shown,

[0029] The invention comprises a base 1 and a screening box 2 supported by the base 1, a sealing box 3 is provided on the screening box 2, a flange 31 for installing a fan is provided on the sealing box 3, a feed port 32 is provided at one end of the sealing box 3, an inclined screen 21 is provided inside the screening box 2, a reciprocating clearing mechanism 4 for removing stuck materials on the inclined screen 21 is provided on the screening box 2, and a power mechanism 5 for driving the screening box 2 to vibrate is also provided on the screening box 2.

[0030] The inner wall of the screening box 2 is provided with an inclined guide plate 33 between the feed port 32 and the upper end of the inclined screen 21 , and the angle between the inclined guide plate 33 and the horizontal plane is greater than the angle between the inclined screen 21 and the horizontal plane.

[0031] Specifically, the angle between the inclined screen 21 and the horizontal plane is 30°, and the angle between the inclined guide plate 33 and the horizontal plane is 45°.

[0032] The material can be effectively screened by the inclined screen 21 in the screening box 2, and molecular sieves of different particle sizes can be quickly separated, thereby improving the screening efficiency.

[0033] The flange 31 at the top of the sealing box 3 is connected to the fan, and during the specific operation of the equipment, the fan is externally connected to the dust removal equipment through a corrugated hose, thereby improving the working environment and the comfort and work efficiency of the operators.

[0034] In addition, the fast air flow in the screening box 2 is achieved through the action of the fan, which helps to maintain the dryness inside. The dry environment is conducive to the flow and screening of materials. Through the action of the fan, the humidity in the screening box is controlled, the passing rate of the material on the screen is improved, and the screening efficiency is significantly improved. It can also reduce the phenomenon of clogging of the inclined screen 21 due to humidity, etc., and can extend the service life of the equipment.

[0035] In this embodiment, the reciprocating cleaning mechanism 4 includes a cleaning roller 41, and both sides of the screening box 2 are provided with an inclined channel 22 allowing the cleaning roller 41 to pass through the inclined channel 22. The ends of the cleaning roller 41 correspond to the inclined channel 22 and are provided with gears 42 at the ends. The side of the screening box 2 is provided with a beveled tooth plate 23, and the gear 42 is meshed on the beveled tooth plate 23. One end of the cleaning roller 41 is provided with a motor for driving the cleaning roller 41, and the inclination angles of the inclined channel 22 and the beveled tooth plate 23 are consistent with the inclination angle of the inclined screen 21.

[0036] The length of the bevel tooth plate 23 is greater than the length of the bevel channel 22 , so as to prevent the gear 42 from being separated from the bevel tooth plate 23 and improve the continuity and stability of use.

[0037] The cleaning roller 41 is driven by the motor and reciprocates along the inclined channel 22 of the screening box 2 through the meshing action of the gear 42 and the inclined tooth plate 23. This movement mode enables the cleaning roller 41 to effectively remove the stuck materials on the inclined screen 21, prevent the inclined screen 21 from being blocked, and ensure the continuity and efficiency of the screening process.

[0038] In addition, the design of the inclined channel 22 and the inclined tooth plate 23 enables the cleaning roller 41 to move stably, and at the same time, its inclination angle is consistent with the inclined screen 21, ensuring the fit between the cleaning roller 41 and the inclined screen 21, thereby improving the cleaning effect. The entire reciprocating cleaning mechanism 4 has a compact structure and occupies a small space, which is beneficial to the overall layout of the screening box.

[0039] In this embodiment, the end of the cleaning roller 41 is rotatably matched with two auxiliary positioning plates 43 spaced apart, and the two auxiliary positioning plates 43 are respectively located on the two sides of the side wall of the screening box 2, and the motor is fixed on the side of the auxiliary positioning plate 43 on the outside.

[0040] Among them, the auxiliary positioning plate 43 can enhance the support and positioning of the cleaning roller 41 on the side wall of the screening box 2 to prevent it from shaking or shifting during operation, thereby ensuring the stable operation of the cleaning roller 41; in addition, by rationally utilizing the side wall space of the screening box 2, the spatial layout is optimized to make it more compact.

[0041] In this embodiment, a cleaning brush is provided on the circumference of the outer surface of the cleaning roller 41 .

[0042] The cleaning brush can effectively remove the stuck materials on the inclined screen 21 as the cleaning roller 41 rotates. The cleaning brush can be optimized according to the material characteristics to ensure that the materials are quickly and thoroughly removed, thereby improving the cleanliness and screening efficiency of the inclined screen 21. The cleaning brush can also reduce the wear and damage to the screen and extend the service life of the screen.

[0043] During specific use, when cleaning is not required, the cleaning roller 41 is placed at the bottom of the inclined channel 22 to avoid interference with the feed screening.

[0044] In this embodiment, the power mechanism 5 includes a vertical plate 51 fixed on the side walls of the screening box 2, and a main shaft 52 is rotatably supported between the two vertical plates 51. The main shaft 52 is fixedly sleeved with a fan-shaped eccentric weight 53, and a first motor for driving the main shaft 52 to rotate is fixedly provided on one side of the vertical plate 51.

[0045] When in use, the first motor drives the main shaft 52 to rotate, so that the fan-shaped eccentric weight 53 fixed on the main shaft 52 generates a rotational motion. Due to the shape and position design of the eccentric weight 53, centrifugal force is generated during the rotation process, thereby driving the screening box 2 to vibrate efficiently. Vibration helps the flow and stratification of materials on the screen, thereby improving the screening efficiency and accuracy.

[0046] In this embodiment, a driven shaft 54 ​​is rotatably supported between the two vertical plates 51 . The driven shaft 54 ​​is driven by the main shaft 52 . A fan-shaped eccentric weight 53 is fixedly sleeved on the driven shaft 54 ​​.

[0047] Specifically, a bottom support plate 55 is fixedly provided between the two vertical plates 51, and two transmission boxes 56 are provided on the bottom support plate 55 and are spaced apart from each other. The main shaft 52 and the driven shaft 54 ​​both pass through the transmission box 56, and a driving gear in the transmission box 56 is fixedly provided on the main shaft 52, and a driven gear in the transmission box 56 is fixedly provided on the driven shaft 54, and the driving gear is meshed with the driven gear.

[0048] The driven shaft 54 ​​is driven in linkage with the main shaft 52, so that the eccentric weights on the two shafts can rotate synchronously, thereby generating superimposed centrifugal force, which enhances the vibration amplitude and frequency of the screening box 2. This enhanced vibration helps the material to flow and stratify more quickly on the screen, further improving the screening efficiency and accuracy.

[0049] Since the two sets of eccentric weights are respectively mounted on the main shaft 52 and the driven shaft 54, their rotational motion can make the vibration of the screening box 2 more uniform. This uniform vibration distribution helps to evenly distribute the material on the screen, reduces the possibility of material accumulation and clogging, and thus improves the uniformity and stability of screening.

[0050] At the same time, the coordinated use of multiple sets of eccentric hammers can also reduce the load of a single eccentric hammer and extend the service life of the equipment.

[0051] In this embodiment, both side surfaces of the screening box 2 are provided with reinforcement supports 24 , and vertical rubber pillars 241 are provided on the reinforcement supports 24 . The bottom surfaces of the rubber pillars 241 are fixed on the base 1 .

[0052] The vertical rubber pillars 241 not only play a supporting role, but more importantly, the rubber material has good buffering and shock absorption performance, which can significantly reduce the transmission of the vibration of the screening box 2 to the base 1 and the surrounding environment, reduce the noise level, and improve the comfort of the working environment.

[0053] The reinforced support 24 and the vertical rubber support 241 thereon provide effective support and shock absorption for the screening box 2, thereby enhancing structural stability, reducing vibration transmission, extending the life of the equipment, and improving screening efficiency.
