[0002] Activated carbon, as a core material for VOCs treatment, is seeing its usage expand continuously. Traditional decentralized carbon replacement methods lead to high transportation costs and a waste carbon regeneration rate of less than 30%. Under these circumstances, fragmented applications are insufficient to meet the needs of closed-loop management throughout the entire process, necessitating the development of a device that overcomes the multiple dilemmas of reliance on manual labor, resource waste, and pollution control.

[0003] Patent CN221981835U discloses an automatic material handling device for activated carbon production equipment. The above patent realizes the use of a suction fan to draw activated carbon dust into the cleaning box through a connecting pipe, and then filter the activated carbon dust through a filter plate, so as to conveniently leave the activated carbon in the cleaning box. The rotating shaft drives the scraper to continuously reciprocate on the filter plate, thereby effectively cleaning the bottom side of the filter plate and preventing activated carbon dust from adhering.

[0004] The aforementioned patent achieves efficient dust cleaning and recycling in activated carbon production equipment through the linkage of suction fan, filter plate, and scraper, effectively reducing workshop pollution and improving material utilization.

[0005] Therefore, this application proposes an automatic material handling device for activated carbon that can achieve automatic material handling and precise flow control through variable diameter spiral blades and bidirectional sealing gates, reducing manual intervention while lowering the material residue rate to below 0.5%.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: an automatic material feeding device for activated carbon, including a frame 1, a feeding mechanism 2, a vibrating screening mechanism 3 and a bidirectional sealing gate 4. The feeding mechanism 2 is horizontally fixedly installed on the top of the outer wall of the frame 1, and the discharge end of the feeding mechanism 2 is connected to the vibrating screening mechanism 3.

[0027] The lower end of the outer wall of the vibrating screening mechanism 3 is provided with a bidirectional sealing gate 4. The bidirectional sealing gate 4 includes a left gate plate 5 and a right gate plate 6. The left gate plate 5 and the right gate plate 6 are symmetrically arranged and a linkage slide rail 7 is connected between the two gate plates. The linkage slide rail 7 is slidably connected to the side of the outer wall of the frame 1. When the left gate plate 5 and the right gate plate 6 are closed, an elastic sealing strip 8 is provided on the inner side.

[0028] Specifically, firstly, the feeding mechanism 2 horizontally conveys the activated carbon particles to the feed inlet of the vibrating screening mechanism 3. The vibrating screening mechanism 3 is driven by a motor to generate high-frequency vibration of the eccentric wheel. Under the action of vibration, the screen separates the particle size of the material. Fine particles fall through the screen holes to the collection chamber at the bottom of the vibrating mechanism, while coarse particles slide along the screen surface to the discharge port for discharge.

[0029] Then, when the activated carbon in the collection chamber reaches the preset amount, the cylinder pushes the left gate 5 and the right gate 6 to slide synchronously to both sides through the linkage slide rail 7, so that the gate opens, the vibrating screening mechanism 3 stops vibrating, and the activated carbon in the collection chamber is discharged through the gate discharge port to the receiving equipment below under the action of gravity.

[0030] Finally, after unloading, the cylinder reverses the drive of the linkage slide rail 7, and the left gate 5 and right gate 6 slide and close in opposite directions. When closed, the elastic sealing strips 8 on the inner side of the two gates are deformed by pressure and tightly fit together to form a sealing surface, preventing external dust from entering or internal gas from leaking. The vibrating screening mechanism 3 resumes vibration and continues to screen subsequent materials, repeating the process.

[0031] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an automatic material handling device for activated carbon. The vibrating screening mechanism 3 includes an eccentric wheel 9, a screen 10, and a support spring 11. A drive shaft installed in the inner hole of the eccentric wheel 9 is connected to the transmission end of the feeding mechanism 2. The screen 10 is obliquely and fixedly installed on the top of the outer wall of the support spring 11. The surface of the screen 10 is distributed with double-layer screen holes, the diameter of the upper screen hole is larger than that of the lower screen hole. A guide plate is provided below the screen 10. The end of the guide plate extends to the feed inlet of the bidirectional sealing gate 4. The surface of the guide plate is provided with guide ridges, which are arranged in an alternating pattern.

[0032] The support springs 11 are arranged symmetrically in a figure-eight shape. The bottom of the outer wall of the support springs 11 is fixed to the crossbeam of the frame 1. The top of the outer wall of the support springs 11 is provided with a ball hinge, which connects to the frame of the screen 10.

[0033] Specifically, firstly, the drive motor of the feeding mechanism (2) drives the spiral blades to rotate, and the activated carbon raw material enters the feed port of the vibrating screening mechanism (3) through the horizontal conveying channel. The drive shaft transmits power to the eccentric wheel (9) of the vibrating screening mechanism (3).

[0034] Then, the eccentric wheel (9) rotates to generate centrifugal force to drive the screen (10) to vibrate. The support spring (11) absorbs the vibration reaction force through the figure-eight symmetrical arrangement. The ball hinge supports the screen (10) to swing freely under the support of the spring. Large particles stay in the upper screen holes, medium particles pass through the upper layer and enter the lower screen holes, and fine powder passes directly through the double-layer screen holes. The guide ribs of the guide plate make the material flow in an "S" shape. The screened material slides down the guide plate to the bidirectional sealing gate (4).

[0035] Finally, the drive unit moves the left gate (5) and right gate (6) synchronously via the linkage slide rail (7). The elastic sealing strip (8) forms a sealing surface when closed to prevent dust leakage. When the gate is opened, large particles are discharged through the left discharge port, medium particles are discharged through the right discharge port, and fine powder is discharged through the bottom discharge port.

[0036] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: an automatic activated carbon feeding device, wherein the linkage slide rail 7 of the bidirectional sealing gate 4 is configured as a dovetail groove, and nylon sliders 12 are fixedly installed on the sliding surfaces of the left gate plate 5 and the right gate plate 6, and the cross section of the elastic sealing strip 8 is configured as a wave shape.

[0037] The outer walls of the left gate plate 5 and the right gate plate 6 are respectively connected to pull rods 13, and the ends of the pull rods 13 are linked to gear racks, and the drive gear of the gear racks is connected to a manual crank handle.

[0038] Specifically, firstly, the feeding mechanism 2 horizontally pushes the activated carbon particles to the feed inlet of the vibrating screening mechanism 3 through a screw conveyor. The eccentric wheel 9 drives the shaft to rotate through the transmission end of the feeding mechanism 2, generating centrifugal force to make the screen 10 vibrate at high frequency. The support springs 11 are arranged symmetrically in a figure-eight shape. The top of the support springs 11 is connected to the frame of the screen 10 through a ball hinge, which evenly transmits the vibration energy to the screen, forming a three-dimensional vibration in the inclined direction, which causes the material to slide along the screen surface.

[0039] Then, the double-layer screen holes on the surface of the screen 10 perform two-stage screening of the material. Large activated carbon particles are intercepted by the upper screen holes and slide along the inclined screen surface to the waste outlet. Small and medium particles penetrate the upper screen holes and continue to be further classified by the lower screen holes. Fine particles enter the guide plate after passing through the screen. The guide ridges on the surface of the guide plate guide the material to converge towards the feed inlet of the bidirectional sealing gate 4, reducing agglomeration and accelerating flow.

[0040] Finally, the manual crank drives the gear and rack mechanism, which pulls the left gate 5 and right gate 6 simultaneously along the linkage slide rail 7 via the pull rod 13. The nylon slider 12 cooperates with the dovetail groove. When the gate is closed, the wave-shaped elastic sealing strip 8 is deformed by pressure, filling the gap between the gates and the frame, providing a bidirectional seal to prevent dust leakage. When unloading, the crank is turned in the opposite direction to separate the gates, and the material is discharged through the gate outlet.

[0041] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: an automatic feeding device for activated carbon, wherein the feeding mechanism 2 includes a variable diameter spiral blade, the pitch of the variable diameter spiral blade gradually decreases from the feeding end to the discharging end, wear-resistant alloy strips are welded to the outer edge of the blade, reinforcing ribs are embedded in the shaft tube of the variable diameter spiral blade, and a flange is provided at the end of the shaft tube, and the flange is coaxially connected to the output shaft of the drive motor.

[0042] The vibrating screening mechanism 3 includes an eccentric wheel 9, a screen 10, and a support spring 11. The drive shaft installed in the inner hole of the eccentric wheel 9 is connected to the transmission end of the feeding mechanism 2. The screen 10 is obliquely fixedly installed on the top of the outer wall of the support spring 11. The surface of the screen 10 is distributed with double-layer screen holes, the diameter of the upper screen hole is larger than that of the lower screen hole. A guide plate is provided below the screen 10. The end of the guide plate extends to the feed inlet of the bidirectional sealing gate 4. The surface of the guide plate is provided with guide ribs, which are arranged in an alternating pattern.

[0043] Specifically, firstly, the output shaft of the drive motor of the feeding mechanism 2 drives the variable diameter spiral blades to rotate through the flange. The pitch of the variable diameter spiral blades gradually decreases from the feed end to the discharge end, so that the activated carbon material has a large space at the feed end. As the spiral blades rotate, the material is gradually pushed forward. Due to the gradually decreasing pitch, the material is squeezed during the conveying process, making the material more compact. The wear-resistant alloy strip welded on the outer edge of the blades reduces the wear of the blades when conveying activated carbon and extends the service life of the blades. The reinforcing ribs embedded in the shaft tube enhance the strength of the shaft tube, making the variable diameter spiral blades more stable during rotation. The feeding mechanism 2 horizontally conveys the activated carbon to the discharge end.

[0044] Then, the transmission end of the feeding mechanism 2 drives the drive shaft installed in the inner hole of the eccentric wheel 9 to rotate. When the eccentric wheel 9 rotates, it will generate an unbalanced centrifugal force. The centrifugal force is transmitted to the screen 10 through the drive shaft. The screen 10 is inclined and fixedly installed on the top of the outer wall of the support spring 11. The support spring 11 is arranged symmetrically in a figure-eight shape. Its bottom end is fixed to the crossbeam of the frame 1, and its top end is connected to the frame of the screen 10 through a ball hinge. The ball hinge makes the screen 10 swing in multiple directions. With the elasticity of the support spring 11, the screen 10 generates high-frequency vibration.

[0045] Finally, when the activated carbon material enters the screen 10 from the discharge end of the feeding mechanism 2, the diameter of the upper screen holes on the surface of the screen 10 is larger than that of the lower screen holes. Large activated carbon particles are intercepted by the upper screen holes and slide to one side along the inclined surface of the screen 10, eventually being discharged as waste. Small and medium-sized activated carbon particles continue to pass through the lower screen holes after passing through the upper screen holes for further screening. Fine activated carbon particles fall onto the guide plate below after passing through the lower screen holes. The staggered guide ridges on the surface of the guide plate change the flow direction of the activated carbon material, causing the material to flow dispersed on the guide plate, avoiding material accumulation, and at the same time accelerating the flow of the material towards the feed port of the bidirectional sealing gate 4.

[0046] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: an automatic feeding device for activated carbon, wherein a buffer base 14 is provided at the bottom of the frame 1, the buffer base 14 includes a rubber pad stacked on top of each other and a disc spring assembly, and the axis of the disc spring assembly is perpendicular to the axis of the feeding mechanism 2.

[0047] The feeding mechanism 2 is horizontally fixedly installed on the top of the outer wall of the frame 1, and the discharge end of the feeding mechanism 2 is connected to the vibrating screening mechanism 3;

[0048] Specifically, firstly, the drive motor of the feeding mechanism 2 drives the variable diameter spiral blades to rotate. The pitch of the variable diameter spiral blades gradually decreases from the feed end to the discharge end. During the rotation, the propulsion force is generated by the pitch contraction, which pushes the activated carbon material along the shaft tube to the discharge end. The wear-resistant alloy strips on the outer edge of the blades come into frictional contact with the material, reducing blade wear.

[0049] Then, the material enters the vibrating screening mechanism 3. The transmission end of the feeding mechanism drives the eccentric wheel 9 to rotate. The centrifugal force generated by the eccentric wheel is transmitted to the screen 10 through the drive shaft. The screen 10 achieves three-dimensional vibration through the ball hinge connection of the support spring 11. The support spring group arranged in a figure-eight shape forms a compound motion trajectory when vibrating. The material is classified on the double-layer screen holes: the upper large-diameter screen holes intercept larger particles, and the lower small-diameter screen holes further screen fine particles. The staggered guide ridges on the surface of the guide plate guide the screened material to slide along the guide plate to the bidirectional sealing gate 4.

[0050] Finally, the gear and rack mechanism is driven by a manual crank, causing the left gate 5 and right gate 6 to slide towards each other along the dovetail groove of the linkage slide rail 7. The low-friction engagement between the nylon slider 12 and the dovetail groove enables smooth opening and closing. The elastic sealing strip 8 with a wavy cross section is deformed under pressure when the gate is closed, forming a dynamic sealing structure. After the gate opening is adjusted, the graded activated carbon material enters the bidirectional sealing gate 4 through the feed inlet at the end of the guide plate and is finally discharged from the discharge outlet. The buffer base 14 at the bottom of the frame 1 absorbs the impact energy generated during the vibrating screening process through a combination of rubber pads and disc springs.

[0051] Working principle: First, the variable diameter spiral blades of the feeding mechanism 2 rotate under the drive of the drive motor. The pitch of the variable diameter spiral blades gradually decreases from the feed end to the discharge end, so that the activated carbon material is gradually compressed and propelled during the conveying process. The wear-resistant alloy strips welded to the outer edge of the blades extend the service life, and the reinforcing ribs embedded in the shaft tube enhance rigidity. The material is stably conveyed to the vibrating screening mechanism 3 through the drive shaft connected by the flange.

[0052] Then, the vibrating screening mechanism 3 drives the screen 10 to generate high-frequency vibration through the eccentric wheel 9. The screen 10 is installed at an angle on the support springs 11 arranged in a figure-eight shape. The ball hinge allows the support springs 11 to swing freely. The double-layer screen holes classify the material. Large particles remain in the upper layer and are discharged through the guide plate. Small particles pass through the lower screen holes. The guide ridges arranged in an alternating pattern on the surface of the guide plate guide the material to flow along the set path and finally converge at the feed port of the bidirectional sealing gate 4.

[0053] Finally, the bidirectional sealing gate 4, driven by a manual crank, uses a rack and pinion mechanism to move the left gate 5 and right gate 6 towards each other along the dovetail groove linkage slide rail 7. When closed, the wavy cross-section elastic sealing strip 8 deforms under pressure to achieve a seal, preventing dust leakage; when open, the gate slides on the slide rail via nylon sliders 12 to control the discharge rate. The buffer base 14 at the bottom of the frame 1, through a combination of rubber pads and disc springs, converts the vibration energy generated by the equipment operation into spring deformation potential energy, reducing the impact on the foundation.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
