DETAILED DESCRIPTION
[0026] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] See also Figure 1-8 The present invention provides a technical solution: a dust-free grinding device for activated carbon processing, comprising a support leg 1, a base 2 is fixedly connected to the upper surface of the support leg 1, a support plate 3 is fixedly connected to the upper surface of the base 2, a support column 4 is fixedly connected to one side surface of the support plate 3, a motor support block 5 is fixedly connected to one side surface of the support plate 3, a pretreatment mechanism 6 is arranged on one side surface of the support plate 3, and a crushing mechanism 7 is arranged on one side surface of the support plate 3;
[0028] The pretreatment mechanism 6 includes an upper shell 601, a feed door 602, a pretreatment motor 603, a pretreatment rotating knife 604, a first crushing protrusion 605, a middle end frame 606, a limit groove 607, a connecting frame 608, a screen 609, a first connecting ring 610, a connecting elastic rope 611, a second connecting ring 612 and a guide plate 613. The upper shell 601 is fixedly connected to one side surface of the support plate 3, the feed door 602 is rotatably connected to one side surface of the upper shell 601, the pretreatment motor 603 is fixedly connected to one side surface of the upper shell 601, the pretreatment motor 603 and the pretreatment rotating knife 604 are fixedly connected to one side surface of the upper shell 601, the first crushing protrusion 605 is fixedly connected to the inner side surface of the upper shell 601, and the lower surface of the upper shell 601 is fixedly connected to the lower surface of the upper shell 601. A middle end frame 606 is fixedly connected, and a limiting groove 607 is provided on the inner surface of the middle end frame 606. A connecting frame 608 is connected to a side surface of the limiting groove 607. A screen 609 is fixedly connected to the inner surface of the connecting frame 608. A first connecting ring 610 is fixedly connected to the inner surface of the connecting frame 608. A connecting elastic rope 611 is bolted to a side surface of the first connecting ring 610. A second connecting ring 612 is bolted to a side surface of the connecting elastic rope 611. A guide plate 613 is fixedly connected to a side surface of the second connecting ring 612. Through the upper shell 601, the feeding door 602, the pretreatment motor 603, the pretreatment rotating knife 604, the first crushing protrusion 605, the middle end frame 606, the limiting groove 607, the connecting frame 608, and the screen 609 , a first connecting ring 610, a connecting elastic rope 611, a second connecting ring 612 and a guide plate 613 are arranged. When in use, the operator opens the feed door 602 of the pretreatment mechanism, pours the activated carbon raw material to be ground into the upper shell 601, and then closes the feed door 602 to prevent dust from overflowing, and then starts the pretreatment motor 603. The pretreatment motor 603 drives the pretreatment rotating knife 604 to rotate at a high speed. At the same time, the multiple groups of first crushing protrusions 605 fixed on the inner surface of the upper shell 601 work together to initially crush and disperse the activated carbon raw material. In this process, the activated carbon particles collide and rub violently with each other and with the rotating knife and crushing protrusions, and gradually become smaller. The preliminarily processed materials fall to the screen 609 below. The interval of the screen 609 The activated carbon beads with a size smaller than that to be crushed can play a preliminary screening role. The qualified materials continue to fall through the screen 609, while the larger particles remain on the screen 609. In addition, the guide plate 613 will guide the materials to fall to the feeding funnel 705 below to complete the pretreatment of the materials. The pretreatment motor 603 drives the multiple groups of pretreatment rotating knives 604 to rotate at high speed. At the same time, combined with the multiple groups of first crushing protrusions 605 on the inner side of the upper shell 601, the two work together to impact, cut and squeeze the activated carbon raw materials from multiple angles, which can quickly crush and disperse the larger blocks of activated carbon raw materials, greatly improving the efficiency of the preliminary treatment, saving time and energy consumption for subsequent fine crushing, and the closed processing method effectively blocks the dust from overflowing.Avoid dust from spreading in the work area during the dumping of raw materials, control dust pollution from the source, greatly improve the workshop environment, protect the health of operators, and reduce the risk of dust explosion.
[0029] Furthermore, four groups of support legs 1 are symmetrically arranged around the central axis of the base 2, and two groups of support plates 3 are symmetrically arranged on the upper surface of the base 2. Through the arrangement of the support legs 1 and the support plates 3, when in use, the four groups of symmetrically distributed support legs 1 can provide uniform and stable bottom support force for the entire dust-free grinding device for activated carbon processing, effectively disperse the weight of the device, avoid safety hazards such as tipping over due to unstable center of gravity, and ensure stability during equipment operation, especially when the pretreatment mechanism 6 and the crushing mechanism 7 run at high speed and generate vibration, they can still remain stable.
[0030] Furthermore, five groups of support columns 4 are arranged between the support plates 3, and the motor support blocks 5 are in a trapezoidal shape, and one is arranged on the lower surface of each motor, so that it is fixedly connected to the support plate 3. Through the arrangement of the support columns 4 and the motor support blocks 5, when in use, the five groups of support columns 4 are distributed between the support plates 3, just like the reinforcing beams in the frame structure, further strengthening the rigidity of the support plate 3. When the device is in operation, especially when the pretreatment mechanism 6 and the crushing mechanism 7 produce vibration and shaking, the support columns 4 can effectively suppress the deformation of the support plate 3, and cooperate with the four groups of symmetrical support legs 1 to comprehensively ensure the stability of the entire device, so that it can withstand greater dynamic loads. The stability characteristics of the trapezoid make its own structure stable and not easy to tip over or move; on the other hand, it provides a solid and adaptive support plane for the pretreatment motor 603, the drum motor 701 and the crushing motor 710.
[0031] Furthermore, the feed door 602 forms a rotating structure with the upper housing 601 through hinges, and six groups of pre-processing rotating knives 604 are arranged on the surface of one side of the pre-processing motor 603, each group is arranged with eight, and the arrangement of the pre-processing rotating knives 604 provides a strong and uniform processing capacity for the initial crushing of the activated carbon raw materials when in use. Multiple groups of rotating knives cut and impact the raw materials from different directions at the same time, which can cover the feeding area in all directions, ensuring that the raw materials in each place can be processed in a timely and effective manner, greatly improving the efficiency of the initial crushing, and accelerating the speed of the materials entering the subsequent processing flow.
[0032] Furthermore, multiple groups of first crushing protrusions 605 are provided on the inner surface of the upper shell 601, and a group of limiting grooves 607 are opened on both sides of the inner side of the middle end frame 606. Through the arrangement of the first crushing protrusions 605, when in use, multiple groups of first crushing protrusions 605 are distributed on the inner side of the upper shell 601, and work together with the pretreatment rotating knife 604, which greatly enhances the crushing ability of the activated carbon raw material. When the pretreatment motor 603 drives the rotating knife to rotate at a high speed, the raw material is subjected to forces from multiple angles under the cutting and impact of the rotating knife and the collision and extrusion of the crushing protrusions, making the block activated carbon easier to be crushed and scattered. Compared with the case of only a rotating knife, this composite action mode can handle raw material blocks of larger size and higher hardness, broadens the scope of application of the device, and improves the efficiency and quality of pretreatment.
[0033] Furthermore, the interval size of the screen 609 is smaller than the size of the activated carbon beads to be crushed, and a group of the first connecting ring 610, the connecting elastic rope 611, the second connecting ring 612 and the guide plate 613 are respectively arranged on the upper sides of the inner side of the middle frame 606. Through the arrangement of the screen 609, when in use, it is ensured that only materials that meet a certain fineness standard can pass through the screen and enter the subsequent crushing process. This precise screening mechanism effectively prevents oversized particles from entering the crushing drum 704 too early, and prevents the uneven particle size of the materials from affecting the quality stability of the final activated carbon powder product.
[0034] Furthermore, the guide plate 613 is in a rotational connection with the middle frame 606, and the connecting elastic rope 611 can carry the guide plate 613 to shrink within a certain range. Through the setting of the guide plate 613 and the connecting elastic rope 611, when in use, the design of the rotational connection enables the guide plate 613 to flexibly adjust the angle according to the actual flow state of the material. When the material falls from the screen 609, if the material landing point is concentrated on one side or the flow direction is deviated due to uneven particle size and flow rate, the guide plate 613 can rotate in real time, change its own inclination, and accurately guide the material to the feed funnel 705 below, ensuring that the material transmission path is always kept optimal, effectively avoiding the material from being scattered to other parts of the device to cause waste or blockage.
[0035] Furthermore, the pulverizing mechanism 7 includes a drum motor 701, an eccentric disk 702, a bearing 703, a pulverizing drum 704, a feeding funnel 705, a connecting column 706, a discharge handle 707, a second pulverizing protrusion 708, a pulverizing rotating knife 709, a pulverizing motor 710, a lower shell 711, a sealing strip 712, a discharge port 713 and a discharge door 714. The upper surface of the motor support block 5 is fixedly connected to the drum motor 701, the side surface of the drum motor 701 is fixedly connected to the eccentric disk 702, the side surface of the eccentric disk 702 is fixedly connected to the bearing 703, and the side surface of the bearing 703 is fixedly connected to the pulverizing drum 704. 04, a feeding funnel 705 is fixedly connected to the upper surface of the pulverizing drum 704, a connecting column 706 is fixedly connected to the side surface of the pulverizing drum 704, a discharge handle 707 is fixedly connected to the side surface of the connecting column 706, a second pulverizing protrusion 708 is fixedly connected to the inner surface of the pulverizing drum 704, a pulverizing rotating knife 709 is rotatably arranged on the inner side of the pulverizing drum 704, a pulverizing motor 710 is fixedly connected to the side surface of the pulverizing rotating knife 709, a lower shell 711 is fixedly connected to the side surface of the pulverizing motor 710, a sealing strip 712 is fixedly connected to the lower surface of the lower shell 711, A discharge port 713 is provided, and a discharge door 714 is provided on one side of the discharge port 713. Through the arrangement of the drum motor 701, the eccentric disk 702, the bearing 703, the pulverizing drum 704, the feeding funnel 705, the connecting column 706, the unloading handle 707, the second pulverizing protrusion 708, the pulverizing rotating knife 709, the pulverizing motor 710, the lower shell 711, the sealing strip 712, the discharge port 713 and the discharge door 714, when in use, after the material enters the pulverizing drum 704, the second pulverizing protrusion 708 fixed on the inner surface and the pulverizing rotating knife 709 driven to rotate by the pulverizing motor 710 further refine the material. Fine grinding, the grinding motor 710 is fixed on one side of the lower shell 711 to provide stable power for the grinding rotating knife 709. After the grinding is completed, the user pushes the unloading handle 707 upwards and opens the discharge door 714 to achieve smooth discharge of the activated carbon powder. The sealing strips 712 fixedly connected to the surface of one side of the lower shell 711, especially the two groups arranged at the openings of the connecting column 706, effectively prevent dust from leaking from the gaps. The whole process is achieved through the coordinated operation of the pretreatment mechanism 6 and the grinding mechanism 7, which not only realizes the efficient grinding of the activated carbon, but also effectively controls the dust generation, meeting the requirements of dust-free and precise grinding of activated carbon processing.The support legs 1, base 2, support plates 3, support columns 4, and motor support blocks 5 serve as the basic support structure of the entire device, providing guarantee for the stable operation of the pretreatment mechanism 6 and the crushing mechanism 7. For example, four groups of support legs 1 are symmetrically arranged with respect to the central axis of the base 2, providing a stable bottom support for the device; two groups of support plates 3 are symmetrically arranged on the upper surface of the base 2 for carrying other components; five groups of support columns 4 are arranged between the support plates 3, which play a role in further strengthening the support; the motor support blocks 5 are in a trapezoidal shape, and one is arranged on the lower surface of each motor, so that it is fixedly connected to the support plate 3 to ensure the stability of the motor during operation.
[0036] Furthermore, the crushing drum 704 rotates eccentrically through the arrangement of the drum motor 701, the eccentric disk 702 and the bearing 703. Two groups of connecting columns 706 are arranged on the surface of one side of the crushing drum 704, and the unloading handle 707 can rotate and unload the crushing drum 704 through the arrangement of the bearing 703. Through the arrangement of the drum motor 701, the eccentric disk 702 and the bearing 703, when in use, the eccentric rotation design makes the movement trajectory of the material in the crushing drum 704 complex and changeable. The drum motor 701 drives the eccentric disk 702 to rotate, thereby driving the crushing drum 704 to run eccentrically. The material in the drum is no longer a single linear tumbling, but is constantly thrown up, dropped, and hits the drum wall and the second crushing protrusion 708 and the crushing rotating knife 709 inside. This all-round, high-intensity collision and friction greatly improves the crushing efficiency, can further refine the pre-treated material, meet the requirements of finer particle size, and is suitable for high-end application fields with strict requirements on the particle size of activated carbon powder.
[0037] Furthermore, two sets of sealing strips 712 are provided at the opening of the lower shell 711 for the connecting column 706. The discharge door 714 is connected to the lower shell 711 through hinges to form a rotational connection. Through the setting of the sealing strips 712, when in use, the setting of the two sets of sealing strips 712 constructs a strict dust-proof barrier for the connection between the pulverizing drum 704 and the lower shell 711. During the activated carbon pulverization process, the violent friction between the material particles and the high-speed operation of the pulverizing parts can easily generate a large amount of fine dust. Once the dust leaks, it will not only pollute the workshop environment and endanger the health of the operators, but also may cause explosion hazards due to dust accumulation. The sealing strips 712 can fit tightly into the gap between the pulverizing drum 704 and the lower shell 711, effectively preventing dust from escaping from the opening of the connecting column 706, and firmly sealing the dust inside the device to ensure the cleanliness and safety of the production environment.
[0038] Working principle: This dust-free grinding device for activated carbon processing is set up through the pretreatment mechanism 6. When in use, the operator opens the feed door 602 of the pretreatment mechanism, pours the activated carbon raw material to be ground into the upper shell 601, and then closes the feed door 602 to prevent dust from overflowing, and then starts the pretreatment motor 603. The pretreatment motor 603 drives the pretreatment rotating knife 604 to rotate at a high speed. At the same time, the multiple groups of first crushing protrusions 605 fixed on the inner surface of the upper shell 601 work together to initially crush and disperse the activated carbon raw material. In this process, the activated carbon particles collide violently with each other and with the rotating knife and crushing protrusions. The friction gradually becomes smaller, and the preliminarily processed materials fall to the screen 609 below. The interval size of the screen 609 is smaller than the size of the activated carbon beads to be crushed, which can play a preliminary screening role. The qualified materials continue to fall through the screen 609, while the larger particles remain on the screen 609, and the guide plate 613 will guide the materials to fall to the feeding funnel 705 below to complete the pretreatment of the materials. The pretreatment motor 603 drives the multiple groups of pretreatment rotating knives 604 to rotate at high speed, and at the same time combines with the multiple groups of first crushing protrusions 605 on the inner side of the upper shell 601. The two work together to impact the activated carbon raw materials from multiple angles. Cutting and extrusion can quickly break up and disperse large blocks of activated carbon raw materials, greatly improving the efficiency of preliminary processing and saving time and energy for subsequent fine crushing. The closed processing method effectively blocks dust spillage and prevents dust from spreading in the working area during the dumping of raw materials. It controls dust pollution from the source, greatly improves the workshop environment, protects the health of operators, and reduces the risk of dust explosion. Through the setting of the crushing mechanism 7, when in use, after the material enters the crushing drum 704, the second crushing protrusion 708 fixed on the inner surface and the crushing rotating knife 709 driven by the crushing motor 710 further crush the material. Fine grinding, the grinding motor 710 is fixed on one side of the lower shell 711 to provide stable power for the grinding rotating knife 709. After the grinding is completed, the user pushes the unloading handle 707 upwards and opens the discharge door 714 to achieve smooth discharge of the activated carbon powder. The sealing strips 712 fixedly connected to the surface of one side of the lower shell 711, especially the two groups arranged at the openings of the connecting column 706, effectively prevent dust from leaking from the gaps. The whole process is achieved through the coordinated operation of the pretreatment mechanism 6 and the grinding mechanism 7, which not only realizes the efficient grinding of the activated carbon, but also effectively controls the dust generation, meeting the requirements of the activated carbon processing for dust-free and precise grinding.The support legs 1, base 2, support plates 3, support columns 4, and motor support blocks 5 serve as the basic support structure of the entire device, providing guarantee for the stable operation of the pretreatment mechanism 6 and the crushing mechanism 7. For example, four groups of support legs 1 are symmetrically arranged with the central axis of the base 2 to provide a stable bottom support for the device; two groups of support plates 3 are symmetrically arranged on the upper surface of the base 2 to carry other components; five groups of support columns 4 are arranged between the support plates 3 to further strengthen the support; the motor support blocks 5 are trapezoidal in shape, and one is arranged on the lower surface of each motor to make them fixedly connected to the support plate 3 to ensure the stability of the motor during operation. The model of the pretreatment motor 603 and the crushing motor 710 is Y315S-2, and the model of the crushing drum 704 is WL-37RS528.
