Description

Technical Field

[0001] This invention relates to the field of raw material processing or pulverizing technology, specifically to a stable pulverizing device and granulation method for carbon molecular sieve granulation. Background Technology

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

[0003] Currently, the commonly used grinding equipment in carbon molecular sieve granulation includes coarse grinding mills, fine grinding mills, and precision grinding mills.

[0004] Traditional hammer mills exhibit several problems when processing carbon molecular sieve raw materials. Firstly, they lack an effective dispersion and guiding mechanism for the material fed into the mill. Larger carbon molecular sieve materials often accumulate near the feed inlet due to this lack of proper guidance, preventing uniform contact between the material and the hammers and resulting in low crushing efficiency. Furthermore, some material remains uncrushed due to accumulation, leading to uneven particle size at the output and affecting the stability of subsequent granulation processes.

[0005] On the other hand, existing hammer mills struggle to precisely control the feed rate for materials of varying volumes. In actual production, the volume of carbon molecular sieve raw materials varies. If the feed volume cannot be flexibly adjusted according to the material volume, overfeeding can easily lead to equipment overload, while underfeeding can reduce production efficiency. For example, when processing smaller raw material particles, if the feed rate is not reduced accordingly, the material inside the mill will become too dense, weakening the impact effect of the hammers. This not only increases energy consumption but may also cause equipment failure due to material blockage. Conversely, when dealing with larger raw materials, insufficient feed rate will prevent the equipment from reaching its full capacity.

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

[0007] To address the shortcomings of existing technologies, this invention provides a stable pulverizing device for carbon molecular sieve granulation, thereby solving the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stable pulverizing device for carbon molecular sieve granulation, comprising: a crushing frame, a crushing chamber provided inside the crushing frame, two sets of main shafts provided inside the crushing chamber, the two sets of main shafts rotating in opposite directions, a set of hammers fixedly connected to each set of main shafts, a dynamic dispersion guiding mechanism provided above the crushing frame, two sets of the dynamic dispersion guiding mechanism, and an eccentric adjustable swing mechanism provided between the two sets of dynamic dispersion guiding mechanisms;

[0009] The dynamic dispersion and guiding mechanism is used to guide and distribute larger carbon molecular sieve raw materials evenly from left to right by swinging left and right, thus avoiding raw material accumulation.

[0010] The eccentric adjustable swing mechanism is used to adjust the swing amplitude for materials of different volumes, thereby controlling the adjustment of the feed volume.

[0011] Preferably, the dynamic dispersion guiding mechanism includes a feed inlet, which is fixedly connected to the top of the crusher frame. An additional trough is fixedly connected to the end of the feed inlet away from the crusher frame. A partition plate is fixedly connected to the middle of the additional trough. Positioning frames are fixedly connected to both sides of the additional trough, and an electrically controlled telescopic rod is fixedly connected inside the positioning frame.

[0012] Preferably, the dynamic dispersion guiding mechanism further includes a T-shaped block, which is rotatably connected to the end of the electrically controlled telescopic rod away from the positioning frame. A driven rod is slidably sleeved on the end of the T-shaped block away from the electrically controlled telescopic rod. A T-shaped groove is formed on the side of the driven rod near the electrically controlled telescopic rod. The T-shaped block is slidably connected in the T-shaped groove. A rotating rod assembly is fixedly connected to the end of the driven rod away from the T-shaped block. A guide plate is fixedly connected to the middle of the rotating rod assembly. The guide plate is rotatably connected to the middle of the partition plate. An inverted V-shaped plate is fixedly connected to the middle of the end of the added groove near the guide plate. The inverted V-shaped plate is parallel to the guide plate.

[0013] Preferably, the eccentric adjustable swing mechanism includes a concentric plate, which is fixedly connected to the middle of the rotating rod assembly. The concentric plate and the rotating rod assembly are at the same center. A housing is fixedly connected to the center of the side of the concentric plate away from the electrically controlled telescopic rod. A trapezoidal groove is formed on the lower part of the side of the housing away from the concentric plate. An annular groove is formed on the upper part of the housing. A trapezoidal block is slidably connected inside the housing. A threaded inner cavity is vertically formed inside the trapezoidal block. An electrically controlled screw is threadedly connected to the inner cavity. A sliding column is fixedly connected to the outer ring of the upper end of the electrically controlled screw. The sliding column is slidably connected in the annular groove. An eccentric disk is fixedly connected to the side of the trapezoidal block away from the housing.

[0014] Preferably, the additional tank is arranged in an inverted trapezoidal shape, the partition plate divides the upper part of the additional tank into two inlets, the additional tank is externally connected to a carbon molecular sieve raw material conveying device, and the electrically controlled telescopic rod is arranged parallel to the side of the additional tank.

[0015] Preferably, the rotating rod assembly consists of two rods, and the guide plate is disposed in the added groove and cooperates with the partition plate to divide the inner cavity of the added groove into two chambers.

[0016] Preferably, the concentric plate and the rotating rod assembly are arranged at the same center, the eccentric disk is located at the eccentric position of the concentric plate, and the side of the eccentric disk away from the concentric plate is fixedly connected to another column in the rotating rod assembly, and this column and the eccentric disk are at the same center.

[0017] The carbon molecular sieve granulation method includes the following steps:

[0018] Step 1: Prepare carbon molecular sieve raw materials, such as coal and coke, and remove any metal blocks, stones and other impurities mixed in the raw materials to prevent them from damaging the hammer mill and affecting its normal operation.

[0019] Step 2: Inspect the components inside the crusher frame, check the wear of the hammer assembly, 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, to ensure adequate lubrication.

[0020] Step 3: The carbon molecular sieve raw material is transported to the additional tank of the crusher frame by the external feeder connected to the additional tank. Under the reciprocating control of the electric telescopic rod, the guide plate is driven to swing through multiple components of the rotating rod group, so that the carbon molecular sieve raw material swings and is guided and diverted to the two chambers of the additional tank for falling.

[0021] Step 4: Depending on the volume of the carbon molecular sieve material being conveyed, the eccentric position of the eccentric disc and the shell is changed by the forward and reverse rotation of the electric screw, thereby changing the eccentric position of the guide plate and the concentric plate, thus changing the swing amplitude of the guide plate, and further adjusting the volume of the material drop outlet in the two chambers of the added trough to avoid material blockage.

[0022] Step 5: The falling carbon molecular sieve raw material is crushed by two sets of hammers. The crushed material is discharged through the discharge port of the crusher frame and transported to the collection hopper or transfer bin by multiple transmission devices such as belt conveyor and screw conveyor.

[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 guiding mechanism, the additional tank is divided into two chambers under the action of the guide plate, thereby diverting the raw materials of carbon molecular sieve crushing. Compared with the traditional single-chamber feed inlet, the raw materials can be more evenly distributed in the two chambers, avoiding material accumulation in the central area of ​​the feed inlet. The design of two chambers increases the material holding space of the feed inlet. With the guiding action of the guide plate, it can effectively buffer the impact of feed speed fluctuations, avoid the aggravation of equipment vibration or overload caused by uneven feeding. Even when there are short-term fluctuations in the feed speed, the material can be effectively regulated in the two chambers, maintaining stable equipment operation, reducing the risk of failure caused by abnormal equipment operation, and ensuring the continuity of the production process.

[0025] 2. By using the reciprocating push of the electrically controlled telescopic rod in conjunction with multiple structures, the left and right swing of the guide plate is controlled, thereby diverting the raw material falling into the crusher frame. This allows the raw material to be more evenly distributed around the two hammer groups, enabling the hammer groups to make more uniform contact with the material during the rotary crushing process. This avoids excessive idling stroke, improves energy utilization, and ensures that the raw material entering the hammer crusher can make uniform contact with the hammer groups. The impact energy it receives in the crushing chamber is more consistent, resulting in more uniform particle size of the crushed material. This reduces local over-crushing or under-crushing caused by material concentration, significantly improving the quality stability of the crushed product.

[0026] 3. By adjusting the eccentricity of the eccentric disc and concentric plate, the initial extrusion force of carbon molecular sieve raw materials of different particle sizes can be adjusted by adjusting the swing angle parameter of the guide plate. This achieves optimal material dispersion while pulverizing, enabling the equipment to adapt to various working conditions. Whether processing large pieces or small particles, it ensures uniform material distribution in both chambers, significantly improving the equipment's versatility and applicability. Furthermore, the opening size of the feed inlet in the two chambers of the additional trough can be intermittently adjusted under the swing amplitude of the guide plate to assist material falling and avoid... This design avoids the accumulation of large particles, which can lead to feeding interruptions due to the arching effect caused by compression. The particle size distribution of subsequent crushing is more controllable, facilitating efficient separation by subsequent screening equipment. It also avoids abnormal fine powder ratios caused by local over-crushing. The swing amplitude can be adjusted according to the different volumes of raw materials, which can correspondingly change the lateral movement of the guide plate. This allows large particles of different volumes to obtain appropriate lateral acceleration when they come into contact with the guide plate, more effectively changing their trajectory and dispersing them onto the hammer assembly. This increases the probability of contact with the hammer assembly, thereby improving the efficiency of single-impact crushing and reducing energy consumption for the same output.

[0046] A further embodiment: Please refer to Figures 5 to 8 As shown:

[0047] The eccentric adjustable swing mechanism 3 is used to adjust the swing amplitude for materials of different volumes, thereby controlling the feed volume. The eccentric adjustable swing mechanism 3 includes a concentric plate 31, which is fixedly connected to the middle of the rotating rod assembly 29. The concentric plate 31 and the rotating rod assembly 29 are located at the same center. A housing 32 is fixedly connected to the center of the side of the concentric plate 31 away from the electrically controlled telescopic rod 25. A trapezoidal groove 33 is opened on the lower part of the side of the housing 32 away from the concentric plate 31. An annular groove 34 is opened on the upper part of the housing 32.

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

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

[0049] Step 1: Prepare carbon molecular sieve raw materials, such as coal and coke, and remove any metal blocks, stones and other impurities mixed in the raw materials to prevent them from damaging the hammer mill and affecting its normal operation.

[0050] Step 2: Inspect the components inside the crusher frame 11, check the wear of the hammer assembly 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 transported to the additional trough 22 of the crusher frame 11 by the external feeder connected to the additional trough 22. Under the reciprocating control of the electric telescopic rod 25, the guide plate 210 is driven to swing by multiple components of the rotating rod group 29, so that the carbon molecular sieve raw material is swung and guided to fall into the two chambers of the additional trough 22.

[0052] Step 4: Depending on the volume of the carbon molecular sieve material being conveyed, the eccentric position of the eccentric disk 39 and the shell 32 is changed by the forward and reverse rotation of the electric screw 35, thereby changing the eccentric position of the guide plate 210 and the concentric plate 31, thus changing the swing amplitude of the guide plate 210, and adjusting the volume of the material drop outlet in the two chambers of the added trough 22 to avoid material blockage.

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

[0054] The working principle of all the content in the above embodiments is as follows:

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

[0056] The following describes the working process of the dynamic dispersion guiding mechanism 2, which uses left and right swinging motion to uniformly guide and distribute larger carbon molecular sieve raw materials from left to right, thus preventing raw material accumulation:

[0057] In use, the raw material conveying device connected to the external of the additional tank 22 conveys the raw material to the top of the additional tank 22. During the conveying process, the raw material falls into the additional tank 22 by gravity, thereby activating the electrically controlled telescopic rod 25 to perform reciprocating telescopic motion. The change in the reciprocating distance of the electrically controlled telescopic rod 25 drives the T-shaped block 28 connected to the electrically controlled telescopic rod 25 to move synchronously. Since the T-shaped block 28 is slidably connected in the T-shaped groove 27, when the T-shaped block 28 retracts towards the electrically controlled telescopic rod 25, the T-shaped block 28 generates a resisting force against the T-shaped groove 27, thereby pushing the end of the driven rod 26 connected to the T-shaped block 28 to deflect towards the electrically controlled telescopic rod 25. When one end of the driven rod 26 deflects, the driven rod 26 is fixedly connected to the rotating rod assembly 29. One end of the rod rotates synchronously in the forward direction around the axis of the rotating rod assembly 29; conversely, when the electrically controlled telescopic rod 25 moves in the telescopic direction, it pushes the T-block 28 to move away from the driven rod 26 in the T-groove 27. At this time, the driven rod 26 rotates in the reverse direction around the axis of the rotating rod assembly 29. Thus, under the reciprocating movement of the electrically controlled telescopic rod 25, the reciprocating sliding position of the T-block 28 in the T-groove 27 is changed, thereby generating a resisting force on the driven rod 26, which in turn causes the driven rod 26 to rotate in both directions. Thus, under the forward and reverse rotation of the rotating rod assembly 29, the guide plate 210 is controlled to swing left and right, thereby swinging the carbon molecular sieve material falling up and down in the added trough 22 left and right, so that it is diverted to the hammer assembly 14 at different positions for crushing.

[0058] By setting up the dynamic dispersion guiding mechanism 2, the additional tank 22 is divided into two chambers under the action of the guide plate 210, thereby performing a diversion operation on the carbon molecular sieve crushing raw material. Compared with the traditional single-chamber feed inlet 21, the raw material can be more evenly distributed in the two chambers, avoiding material accumulation in the central area of ​​the feed inlet 21. The design of two chambers increases the material holding space of the feed inlet 21. With the guiding action of the guide plate 210, it can effectively buffer the impact of feed speed fluctuations, avoid the aggravation of equipment vibration or overload caused by uneven feeding. Even when there are short-term fluctuations in the feed speed, the material can be effectively regulated in the two chambers, maintaining stable equipment operation, reducing the risk of failure caused by abnormal equipment operation, and ensuring the continuity of the production process.

[0059] By using the reciprocating push of the electrically controlled telescopic rod 25 in conjunction with multiple structures, the guide plate 210 is controlled to swing left and right, thereby diverting the raw material falling into the crusher frame 11. This allows the raw material to be more evenly distributed around the two hammer groups 14, thus enabling the hammer groups 14 to make more even contact with the material during the rotary crushing process. This avoids excessive idling stroke, improves energy utilization, and ensures that the raw material entering the hammer crusher can make even contact with the hammer groups 14. The impact energy it receives in the crushing chamber 12 is more consistent, resulting in more consistent particle size of the crushed material. This reduces local over-crushing or under-crushing caused by material concentration, and significantly improves the quality stability of the crushed product.

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

[0061] The following describes the working process of the eccentric adjustable oscillating mechanism 3, which is used to adjust the swing amplitude for materials of different volumes, thereby controlling the feed volume:

[0062] In use, during the process of left and right swinging diversion of the guide plate 210 driven by the dynamic dispersion guide mechanism 2, it is used in conjunction with the carbon molecular sieve raw material conveying equipment connected to the external trough 22. If the raw material volume is large, the electric control screw 35 is started to rotate forward by the external controller. During the forward rotation of the electric control screw 35, the trapezoidal block 37, which is threaded to the electric control screw 35 through the threaded inner cavity 38, moves vertically downward in the trapezoidal slide 33. Since the eccentric disk 39 is fixedly connected to the trapezoidal block 37, and the two columns in the rotating rod assembly 29 are... Since the eccentric disk 39 and the concentric plate 31 are not at the same center position, when the eccentric disk 39 moves downward into the trapezoidal groove 33 under the drive of the trapezoidal block 37, it simultaneously drives the column of one of the rotating rod groups 29 to move towards the eccentric position of the concentric plate 31, thereby changing the eccentric distance and making the eccentric distance larger. Correspondingly, the two columns in the rotating rod group 29 also undergo eccentric adjustment. At this time, the guide plate 210 gradually shifts off-center from the concentric plate 31 along with the column in the eccentric rotating rod group 29. Therefore, when the electrically controlled telescopic rod 25 drives the driven rod 26 to swing, the guide plate 210... As the eccentricity of plate 210 increases, the swing amplitude of guide plate 210 is correspondingly enhanced under the same reciprocating drive. During the swing amplitude diversion process of guide plate 210, it simultaneously cooperates with the inner wall of the added trough 22, and performs preliminary compression on the large-volume raw materials falling up and down in the added trough 22 during the swing process, thereby preventing the raw materials falling into the hammer group 14 from being too large in volume. Furthermore, the large-volume raw material particles have a larger mass and have 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, so the lateral thrust of guide plate 210 is not large. This is sufficient to overcome the inertia of large particles. Increasing the swing amplitude can extend the lateral movement stroke of the guide plate 210, allowing large particles to obtain greater lateral acceleration when they contact the guide plate 210, thereby effectively changing their trajectory and forcing them to diffuse to the left and right sides. This avoids the material from concentrating in the central area of ​​the feed inlet, which could lead to subsequent material blockage. The probability of the dispersed material contacting the hammer is increased, thus improving the single impact crushing efficiency. With the assistance of the inverted V-shaped plate 211, the material is further dispersed and guided as it flows along the inner wall of the added trough 22 and the surface of the guide plate 210.

[0063] By adjusting the eccentricity of the eccentric disc 39 and the concentric plate 31, the initial extrusion force of carbon molecular sieve raw materials of different particle sizes can be adjusted by adjusting the swing angle parameter of the guide plate 210. This allows for optimal material dispersion while pulverizing the raw materials, enabling the equipment to adapt to various working conditions. Whether processing large or small raw materials, the equipment ensures uniform material distribution within the two chambers, significantly improving its versatility and applicability. Furthermore, the size of the discharge port openings of the two chambers of the added trough 22 can be intermittently adjusted under the swing amplitude of the guide plate 210 to assist material descent and prevent... This design avoids the accumulation of large particles, which can lead to feeding interruptions due to the arching effect caused by compression. The particle size distribution of subsequent crushing is more controllable, facilitating efficient separation by subsequent screening equipment. It also avoids abnormal fine powder ratios caused by local over-crushing. The swing amplitude can be adjusted according to the different volumes of raw materials, which can correspondingly change the lateral movement of the guide plate 210. This allows large particles of different volumes to obtain appropriate lateral acceleration when they come into contact with the guide plate 210, more effectively changing their movement trajectory and dispersing them onto the hammer group 14. This increases the probability of contact with the hammer group 14, better improving the efficiency of single impact crushing and reducing energy consumption for the same output.

7. A carbon molecular sieve granulation method, applied to the stable pulverizing device for carbon molecular sieve granulation as described in claim 6, characterized in that: Includes the following steps: Step 1: Prepare carbon molecular sieve raw materials, such as coal and coke. Remove any metal blocks or stones mixed in with the raw materials to prevent them from damaging the hammer mill and affecting its normal operation. Step 2: Inspect the components inside the crusher frame (11), check the wear of the hammer assembly (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; Step 3: The carbon molecular sieve raw material is transported to the additional trough (22) of the crusher frame (11) by the external feeder connected by the additional trough (22). Under the reciprocating control of the electric 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 swung and guided to fall into the two chambers of the additional trough (22). Step 4: Depending on the volume of the carbon molecular sieve material being transported, the eccentric position of the eccentric disk (39) and the shell (32) is changed by the forward and reverse rotation of the electric screw (35), thereby changing the eccentric position of the guide plate (210) and the concentric plate (31), thus changing the swing amplitude of the guide plate (210), and then adjusting the volume of the material drop outlet in the two chambers of the added trough (22) to avoid material blockage. Step 5: The falling carbon molecular sieve raw material is crushed under the setting of two sets of hammer groups (14). The crushed material is discharged through the discharge port of the crusher frame (11). Multiple transmission equipment such as belt conveyor and screw conveyor are used to transport the material to the collection hopper or transfer bin for collection.
