Description

Technical Field

[0001] The invention relates to the technical field of raw material processing or crushing subdivision, in particular to a stable crushing device for carbon molecular sieve granulation and a granulation method thereof. Background Art

[0002] In modern industry, carbon molecular sieves, due to their excellent adsorption and separation properties, are widely used in key processes such as pressure swing adsorption nitrogen production and gas separation and purification. The performance of carbon molecular sieves is closely related to the quality of granulation. The raw material pulverization process, as a core step before granulation, plays a decisive role in the performance of the final product.

[0003] At present, the pulverizing equipment commonly used in carbon molecular sieve granulation includes coarse grinding mill, fine grinding mill, fine grinding mill, etc.

[0004] Traditional hammer mills present numerous problems when processing carbon molecular sieve raw materials. For one thing, they lack an effective dispersion and guidance mechanism for the material being conveyed into the mill. Larger carbon molecular sieve raw materials often accumulate near the feed inlet due to a lack of proper guidance. This prevents uniform contact between the material and the hammers, leading to low pulverization efficiency. This accumulation also prevents some material from being fully pulverized, resulting in uneven discharge particle size and impacting the stability of the subsequent granulation process.

[0005] On the other hand, existing hammer mills have difficulty accurately controlling the feed rate for materials of varying volumes. In actual production, the volumes of carbon molecular sieve raw materials vary. If the feed volume cannot be flexibly adjusted based on the material volume, it is easy for excessive feed to cause equipment overload, or insufficient feed to reduce production efficiency. For example, when processing smaller raw material particles, if the feed rate is not reduced accordingly, the material in the mill will become too dense, and the hammer impact effect will be weakened, which will not only increase energy consumption but may also cause equipment failure due to material congestion. On the other hand, when dealing with larger raw materials, if the feed rate is insufficient, the equipment's production capacity cannot be fully utilized.

[0006] Therefore, a stable pulverizing device for carbon molecular sieve granulation is proposed to solve the above problems. Summary of the Invention

[0019] Step 2: Check the components inside the crusher frame, check the wear of the hammer group, and add an appropriate amount of lithium-based grease or lubricating oil to the transmission parts including the main shaft bearings and couplings to ensure sufficient lubrication;

[0020] Step 3: The carbon molecular sieve raw material is transported to the additional trough of the crushing frame through an external feeder connected to the additional trough. Under the reciprocating control of the electric telescopic rod, the guide plate is driven to swing through multiple components of the rotating rod group, and the carbon molecular sieve raw material is swing-guided and diverted into the two chambers of the additional trough for falling;

[0023] Compared with the prior art, the present invention provides a stable pulverizing device for carbon molecular sieve granulation, which has the following beneficial effects:

[0024] 1. By setting up a dynamic dispersion guide mechanism, the additional trough body is divided into two chambers under the action of the guide plate, and then the carbon molecular sieve crushed raw material is diverted. Compared with the traditional single-chamber feed inlet, the raw materials can be more evenly distributed in the two chambers, avoiding the accumulation of materials in the central area of ​​the feed inlet. The design of the two chambers increases the material holding space of the feed inlet. Combined with the guiding effect of the guide plate, it can effectively buffer the impact of feed speed fluctuations and avoid increased equipment vibration or overload caused by uneven feeding. Even when the feed speed fluctuates for a short time, the material can be effectively adjusted in the two chambers to maintain stable operation of the equipment, reduce the risk of failure caused by abnormal operation of the equipment, and ensure the continuity of the production process.

[0025] 2. The reciprocating push of the electric-controlled telescopic rod is used in conjunction with multiple structures to control the left and right swing of the guide plate, thereby performing a diversion operation on the raw materials falling into the crusher frame, so that the raw materials are more evenly distributed around the two hammer groups, thereby better enabling the hammer groups to contact the materials more evenly during the rotary crushing process, avoiding an excessively high proportion of idling stroke, and improving energy utilization. The raw materials entering the hammer crusher can evenly contact the hammer groups, and the impact energy they receive in the crushing chamber is more consistent, so that the particle size of the crushed materials is more consistent, reducing the phenomenon of local over-crushing or under-crushing due to material concentration, and significantly improving the quality stability of the crushed products.

[0026] 3. Through the eccentric adjustment of the eccentric disk and the concentric plate, for carbon molecular sieve raw materials of different particle sizes, by adjusting the swing angle parameters of the guide plate, the initial extrusion force of raw materials of different volumes can be adjusted, so that the best material dispersion effect can be achieved while crushing, so that the equipment can adapt to various working conditions. Whether it is processing large pieces of raw materials or small particles of raw materials, it can ensure that the materials are evenly distributed in the two chambers, which significantly improves the versatility and applicability of the equipment. In addition, the opening size of the discharge port of the two chambers of the additional trough body can be intermittently adjusted under the swing amplitude of the guide plate to assist the material to fall and avoid Avoid the accumulation of large particles, and the interruption of feeding caused by the arch bridge effect formed by extrusion. The subsequent crushing particle size distribution is more controllable, which is convenient for the efficient separation of subsequent screening equipment, and avoids the abnormal proportion of fine powder due to local over-crushing. The swing amplitude is adjusted according to the different volumes of raw materials, and the lateral movement process of the guide plate can be changed accordingly, so that large particles of raw materials of different volumes can obtain appropriate lateral acceleration when contacting the guide plate, more effectively change their movement trajectory, disperse them to the hammer group, increase the probability of contact with the hammer group, better improve the efficiency of single impact crushing, and reduce energy consumption under the same output.

The side of the eccentric disc 39 away from the concentric plate 31 is fixedly connected to another column rod in the rotating rod group 29, and this column rod and the eccentric disc 39 are at the same center of a circle.

[0048] The carbon molecular sieve granulation method is as follows:

[0049] Step 1: Prepare carbon molecular sieve raw materials, coal, and coke materials, and remove metal blocks, stones and other debris mixed in the raw materials to prevent them from entering the hammer mill and damaging the equipment, affecting normal operation;

[0050] Step 2: Check the components inside the crusher frame 11, check the wear of the hammer group 14, and add an appropriate amount of lithium-based grease or lubricating oil to the transmission components including the bearings and couplings of the main shaft 13 to ensure sufficient lubrication;

[0051] Step 3: The carbon molecular sieve raw material is delivered to the additional trough 22 of the crushing frame 11 through an external feeder connected to the additional trough 22. Under the reciprocating control of the electrically controlled telescopic rod 25, the guide plate 210 is driven to swing by multiple components of the rotating rod group 29, and the carbon molecular sieve raw material is swing-guided and diverted into the two chambers of the additional trough 22 for falling;

[0052] Step 4: According to the different volumes of carbon molecular sieve materials to be transported, the eccentric position of the eccentric disk 39 and the housing 32 is changed under the forward and reverse rotation of the electric control screw 35, thereby changing the eccentric position of the guide plate 210 and the concentric plate 31, thereby changing the swing amplitude of the guide plate 210, and further adjusting the volume of the material drop openings in the two chambers of the additional trough body 22 to avoid material blockage;

[0053] Step 5: The falling carbon molecular sieve raw material is crushed under the setting of two groups of hammer groups 14, and the crushed material is discharged through the discharge port of the crushing frame (11). The material is transported to the collecting hopper or transfer silo for collection using multiple transmission equipment such as belt conveyors and screw conveyors.

[0054] Everything in the above example works as follows:

[0055] In the initial state: the eccentric disc 39 and the concentric plate 31 are at the same center, and the guide plate 210 is perpendicular to the crushing frame 11.

[0056] The following is the working process of the dynamic dispersion guide mechanism 2 for evenly distributing larger carbon molecular sieve raw materials to the left and right by swinging left and right to avoid accumulation of raw materials:

[0057] When in use, the material conveying device connected to the additional trough body 22 conveys the material to the top of the additional trough body 22. During the conveying process of the material, it falls into the additional trough body 22 due to gravity, and then the electric-controlled telescopic rod 25 is started to perform reciprocating telescopic motion. The change in the reciprocating movement distance of the electric-controlled telescopic rod 25 drives the T-block 28 connected to the electric-controlled telescopic rod 25 to move synchronously. Since the T-block 28 is slidably connected in the T-slot 27, when the T-block 28 contracts and moves toward the electric-controlled telescopic rod 25, the T-block 28 generates a resistance force on the T-slot 27, thereby pushing the end of the driven rod 26 connected to the T-block 28 to deflect toward the electric-controlled telescopic rod 25. When one end of the driven rod 26 deflects, the driven rod 26 is fixedly connected to the rotating rod group 29 One end of the driven rod 26 rotates synchronously with the axis of the rotating rod group 29 in the forward direction; on the contrary, when the electrically controlled telescopic rod 25 is telescopically moved, the T-shaped block 28 is pushed to move in the T-shaped slot 27 toward the end away from the driven rod 26. At this time, the driven rod 26 is prompted to rotate in the opposite direction with the axis of the rotating rod group 29. As a result, under the reciprocating movement of the electrically controlled telescopic rod 25, the reciprocating sliding position of the T-shaped block 28 in the T-shaped slot 27 is changed, thereby generating a resistance force on the driven rod 26, and then causing the driven rod 26 to rotate at a positive and negative angle. As a result, under the positive and negative rotation of the rotating rod group 29, the guide plate 210 is controlled to swing left and right, thereby swinging the carbon molecular sieve material falling on and off the additional trough body 22 left and right, so that it is diverted to the hammer groups 14 at different positions for crushing operation;

[0058] By setting up the dynamic dispersion guide mechanism 2, the additional trough body 22 is divided into two chambers under the action of the guide plate 210, and then the carbon molecular sieve crushed raw material is diverted. Compared with the traditional single-chamber feed inlet 21, the raw materials can be more evenly distributed in the two chambers, avoiding the accumulation of materials in the central area of ​​the feed inlet 21. The design of the two chambers increases the material holding space of the feed inlet 21. Combined with the guiding effect of the guide plate 210, it can effectively buffer the impact of feed speed fluctuations and avoid increased equipment vibration or overload caused by uneven feeding. Even when the feed speed fluctuates for a short time, the material can be effectively adjusted in the two chambers to maintain stable operation of the equipment, reduce the risk of failure caused by abnormal operation of the equipment, and ensure the continuity of the production process.

[0059] By reciprocatingly pushing the electrically controlled telescopic rod 25 in conjunction with a plurality of structures, the left and right swing of the guide plate 210 is controlled, thereby performing a diversion operation on the raw materials falling into the crusher frame 11, so that the raw materials are more evenly distributed around the two hammer groups 14, thereby better enabling the hammer groups 14 to more evenly contact the materials during the rotary crushing process, avoiding an excessively high proportion of idling stroke, improving energy utilization, and enabling the raw materials entering the hammer crusher to evenly contact the hammer groups 14. The impact energy received by the raw materials in the crushing chamber 12 is more consistent, thereby making the particle size of the crushed materials more consistent, reducing the phenomenon of local over-crushing or under-crushing due to material concentration, and significantly improving the quality stability of the crushed products.

[0060] Please refer to the above working process Figures 1 to 5 .

[0061] The following is the working process of the eccentric adjustable swing mechanism 3 for adjusting the swing amplitude for materials of different volumes and thus controlling the feed volume:

[0062] When in use, in the process of swinging left and right by driving and controlling the guide plate 210 of the dynamic dispersion guide mechanism 2, it is used in conjunction with the carbon molecular sieve raw material conveying equipment externally connected to the additional tank body 22. If the raw material volume is large, the electric control screw 35 is started by the external controller to rotate forward. During the forward rotation of the electric control screw 35, the trapezoidal block 37 threadedly connected to the electric control screw 35 through the threaded inner cavity 38 moves vertically downward in the trapezoidal chute 33. Since the eccentric disk 39 is fixedly connected to the trapezoidal block 37, and the two rods in the rotating rod group 29 are separated, the electric control screw 35 rotates forward. The eccentric disc 39 and the concentric plate 31 are at the same center position. Therefore, when the eccentric disc 39 moves downward into the trapezoidal slide 33 under the drive of the trapezoidal block 37, the eccentric disc 39 is synchronously driven to drive the column of one of the rotating rod groups 29 to move toward the eccentric position of the concentric plate 31, thereby changing the eccentric distance and making the eccentric distance larger. The two columns in the corresponding rotating rod group 29 are also eccentrically adjusted. At this time, the guide plate 210 gradually deviates from the eccentricity of the concentric plate 31 along with the column in the eccentric rotating rod group 29. Therefore, when the electric control telescopic rod 25 drives the driven rod 26 to swing, the guide plate 210 is The eccentric distance of the plate 210 is increased, so under the same reciprocating drive, the swing amplitude of the guide plate 210 is correspondingly enhanced. During the swing amplitude diversion process of the guide plate 210, it is synchronously coordinated with the inner wall of the additional trough body 22, and the large-volume raw materials falling from the additional trough body 22 are initially squeezed during the swing process, so that the raw materials falling into the hammer group 14 to be crushed do not have a large volume. Furthermore, the large-volume raw material particles have a larger mass and have a stronger motion inertia when falling under the action of gravity, which easily forms a vertical falling accumulation trend. At this time, the swing amplitude is small, and the lateral thrust of the guide plate 210 is not large. It is sufficient to overcome the inertia of large particles. Increasing the swing amplitude can extend the lateral movement stroke of the guide plate 210, so that the large particles obtain greater lateral acceleration when contacting the guide plate 210, thereby effectively changing their movement trajectory and forcing them to diffuse to the left and right sides, avoiding concentration in the central area of ​​the feed inlet, which may cause subsequent material blockage. The probability of the dispersed material contacting the hammer head is increased, and the single impact crushing efficiency is improved. With the assistance of the inverted V-shaped plate 211, the material is further dispersed and diverted when it flows along the inner wall of the additional trough body 22 and the surface of the guide plate 210.

[0063] By adjusting the eccentricity of the eccentric disk 39 and the concentric plate 31, for carbon molecular sieve raw materials of different particle sizes, by adjusting the swing angle parameters of the guide plate 210, the initial extrusion force of raw materials of different volumes can be adjusted, so that the best material dispersion effect can be achieved while crushing, so that the equipment can adapt to various working conditions. Whether it is processing large pieces of raw materials or small particles of raw materials, it can ensure that the materials are evenly distributed in the two chambers, which significantly improves the versatility and applicability of the equipment. In addition, the opening size of the discharge port of the two chambers of the additional trough body 22 is intermittently adjusted under the swing amplitude of the guide plate 210 to assist the material in falling and avoid The accumulation of large particles is avoided, and the feeding interruption is caused by the arch bridge effect formed by extrusion. The subsequent crushing particle size distribution is more controllable, which is convenient for the efficient separation of the subsequent screening equipment, and avoids the abnormal fine powder ratio due to local over-crushing. The swing amplitude is adjusted according to the different volumes of raw materials, and the lateral movement process of the guide plate 210 can be changed accordingly, so that large particles of raw materials of different volumes can obtain appropriate lateral acceleration when contacting the guide plate 210, and their movement trajectory is changed more effectively, and they are dispersed on the hammer group 14, thereby increasing the contact probability with the hammer group 14, better improving the single impact crushing efficiency, and reducing energy consumption under the same output.
