Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon sand removal, specifically to an activated carbon sand removal device. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials (such as fruit shells, coal, and wood) are heated in the absence of air to reduce non-carbon components (this process is called carbonization). Then, they react with gases, and the surface is eroded, creating a structure with well-developed micropores (this process is called activation). Because the activation process is a microscopic process, the surface erosion of a large number of molecular carbides is point erosion, resulting in countless tiny pores on the surface of activated carbon.

[0003] Activated carbon requires sand removal during production. A search revealed a utility model patent in China with publication number CN221335234U, which discloses an activated carbon sand removal device, including a sand removal box. In use, activated carbon is first poured into the sand removal box through the inlet. Then, a motor and vibrator are simultaneously started. The motor drives a rotating rod, which in turn drives a spiral blade, causing the activated carbon to tumble. Simultaneously, the vibrator vibrates, causing a filter plate to vibrate. This vibration causes the continuously tumbling activated carbon to fall off, passing through the filter plate onto a guide plate below and being discharged from the sand outlet. After sand removal is complete, the control valve is opened, allowing the activated carbon to be discharged from the outlet along the inclined filter plate.

[0004] However, existing activated carbon sand removal devices still have some problems in use. For example, the device does not have a shock absorption function. During use, due to the continuous vibration of the entire device, the equipment is prone to fatigue and accelerated damage. In addition, the device only has one set of filter plates, which can only remove sand from activated carbon larger than the filter holes on the filter plates, making it less practical. Therefore, an activated carbon sand removal device is needed to solve the above-mentioned problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, this utility model provides an activated carbon sand removal device to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon sand removal device, comprising a sand removal box, a feed hopper at the top of the sand removal box, and further comprising:

[0009] The screening mechanism and the shock absorption mechanism are arranged in two sets, one above the other. The upper screening mechanism can screen larger particles in the activated carbon, while the lower screening mechanism is used to screen smaller activated carbon particles that are missed by the upper screening mechanism. The shock absorption mechanism is installed at the bottom of the sand removal box and is used to reduce the vibration of the sand removal box.

[0010] Both screening mechanisms include a filter plate, four mounting plates, four fixing plates, four springs, and a vibrator. The filter plate is inclined inside the sand removal box. The four mounting plates are connected to the front and rear ends of the filter plate. The four fixing plates are connected to the front and rear ends of the inner side wall of the sand removal box. The bottom ends of the four springs are connected to the top ends of the four fixing plates, and the top ends of the four springs are connected to the bottom ends of the four mounting plates. The vibrator is connected to the bottom end of the filter plate. A discharge port is provided on one side of the sand removal box, and the filter plate is located at the discharge port on one side. A guide hopper is provided at the bottom end of the upper filter plate. The bottom end of the guide hopper is located above the lower filter plate and away from the discharge port. The filter plate is provided with multiple sets of filter holes. The hole diameter of the upper filter plate is larger than that of the lower filter plate. A sand discharge port is provided at the bottom of the sand removal box on the side away from the discharge port.

[0011] Preferably, the shock absorption mechanism includes four sets of spring shock absorbers and a base plate. The tops of the four sets of spring shock absorbers are symmetrically connected to the bottom of the sand removal box, and the bottoms of the four sets of spring shock absorbers are connected to the top of the base plate.

[0012] Preferably, a U-shaped baffle is provided at the top edge of the filter plate.

[0013] Preferably, the bottom end of the base plate is provided with multiple sets of adjusting screws.

[0014] Preferably, the bottom end of each of the four sets of adjusting screws is provided with a rubber pad.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an activated carbon sand removal device, which has the following beneficial effects:

[0017] In use, the upper screening mechanism can first screen the larger particles in the activated carbon to prevent large pieces of material from clogging the fine-pore filter plate below. The smaller activated carbon particles after the upper screening are then subjected to secondary fine sand removal by the lower screening mechanism. This not only enables precise sand removal for activated carbon of different particle sizes, but also covers the treatment needs of activated carbon with a wider range of particle sizes. This greatly improves the adaptability of the device to sand removal operations for activated carbon of different specifications and effectively avoids the problems of incomplete sand removal or low filtration efficiency caused by a single filtration stage.

[0018] In both screening mechanisms, the filter plates are inclined and equipped with vibrators. A guide hopper is located at the bottom of the upper filter plate, precisely aligned with the position of the lower filter plate furthest from the discharge port. The vibrator drives the inclined filter plates to vibrate, accelerating the separation of activated carbon and sand. The inclined structure also guides the activated carbon along the filter plates using gravity, preventing material accumulation. Furthermore, the guide hopper precisely guides the screened activated carbon from the upper plate to the starting point of the lower filter plate, ensuring that each sample of material undergoes a thorough screening process, preventing incomplete screening due to direct material falling and further guaranteeing sand removal efficiency and effectiveness. In addition, the discharge port on one side of the sand removal box precisely aligns with one side of the filter plate, facilitating the rapid discharge of qualified activated carbon after screening. The sand discharge port on the bottom of the sand removal box, furthest from the discharge port, collects sand that has fallen from both stages of screening, achieving efficient separation and separate discharge of materials and impurities.

[0019] This vibration damping mechanism can effectively absorb the vibration energy generated by the vibrator and material flow during the operation of the device, reduce the overall vibration amplitude of the device, and avoid problems such as structural fatigue, loosening of parts or accelerated wear caused by long-term continuous vibration. It significantly reduces the probability of equipment failure and extends the overall service life of the equipment. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figures 1-5 An activated carbon sand removal device includes a sand removal box 1, a feed hopper 2 at the top of the sand removal box 1, and further includes:

[0029] The screening mechanism and the shock absorption mechanism are provided. There are two screening mechanisms, which are arranged vertically. The upper screening mechanism can screen larger particles in the activated carbon, and the lower screening mechanism is used to screen smaller activated carbon particles that are missed by the upper screening mechanism. The shock absorption mechanism is installed at the bottom of the sand removal box 1 and is used to absorb vibrations in the sand removal box 1.

[0030] Both sets of screening mechanisms include a filter plate 3, four sets of mounting plates 4, four sets of fixing plates 5, four sets of springs 6, and a vibrator 7. The filter plate 3 is inclined inside the sand removal box 1. The four sets of mounting plates 4 are connected to the front and rear ends of the filter plate 3. The four sets of fixing plates 5 are connected to the front and rear ends of the inner side wall of the sand removal box 1. The bottom ends of the four sets of springs 6 are connected to the top ends of the four sets of fixing plates 5 respectively. The top ends of the four sets of springs 6 are connected to the bottom ends of the four sets of mounting plates 4 respectively. The vibrator 7 is connected to the bottom end of the filter plate 3. A discharge port 8 is provided on one side of the sand removal box 1. The filter plate 3 is located at the discharge port 8 on one side. A guide hopper 9 is provided at the bottom end of the upper filter plate 3. The bottom end of the guide hopper 9 is located above the lower filter plate 3 and away from the discharge port 8. The filter plate 3 is provided with multiple sets of filter holes. The hole diameter of the upper filter plate 3 is larger than that of the lower filter plate 3. A sand discharge port 10 is provided at the bottom of the sand removal box 1 on the side away from the discharge port 8.

[0031] In use, the upper screening mechanism can first screen the larger particles in the activated carbon to prevent large pieces of material from clogging the fine-pore filter plate 3 below. The smaller activated carbon particles after the upper screening are then subjected to secondary fine sand removal by the lower screening mechanism. This not only enables precise sand removal for activated carbon of different particle sizes, but also covers the treatment needs of activated carbon with a wider range of particle sizes. This greatly improves the adaptability of the device to sand removal operations of activated carbon of different specifications and effectively avoids the problems of incomplete sand removal or low filtration efficiency caused by a single filtration stage.

[0032] In both screening mechanisms, the filter plates 3 are inclined and equipped with vibrators 7. A guide hopper 9 is located at the bottom of the upper filter plate 3, precisely corresponding to the position of the lower filter plate 3 furthest from the discharge port 8. The vibrator 7 drives the inclined filter plates 3 to vibrate, accelerating the separation of activated carbon and sand. The inclined structure also guides the activated carbon along the filter plates 3 by gravity, preventing material accumulation. Furthermore, the guide hopper 9 precisely guides the screened activated carbon from the upper filter plate 3 to the starting point of the lower filter plate 3, ensuring that each sample of material undergoes sufficient screening and preventing incomplete screening due to direct material drop, thus further guaranteeing sand removal efficiency and effect. In addition, the discharge port 8 on one side of the sand removal box 1 precisely aligns with one side of the filter plate 3, facilitating the rapid discharge of qualified activated carbon after screening. The sand discharge port 10 at the bottom of the sand removal box 1, furthest from the discharge port 8, collects the sand dropped from both screening stages, achieving efficient separation and separate discharge of materials and impurities.

[0033] This vibration damping mechanism can effectively absorb the vibration energy generated by the operation of the vibrator 7 and the flow of materials during the operation of the device, reduce the overall vibration amplitude of the device, avoid structural fatigue, loosening of parts or accelerated wear due to long-term continuous vibration, significantly reduce the probability of equipment failure and extend the overall service life of the equipment.

[0034] Please see Figures 1-5 The vibration damping mechanism includes four sets of spring dampers 11 and a base plate 12. The tops of the four sets of spring dampers 11 are symmetrically connected to the bottom of the sand removal box 1, and the bottoms of the four sets of spring dampers 11 are connected to the tops of the base plate 12. The four sets of spring dampers 11 are symmetrically distributed, which can evenly absorb vibration energy from the four key support points at the bottom of the sand removal box 1. Compared with a single or asymmetrical damping structure, it can effectively avoid problems such as tilting and shaking of the sand removal box 1 due to uneven force, and further improve the stability of the device during operation. The spring dampers 11 have good elastic adjustment capability and can adaptively adjust the damping force according to the working intensity of the vibrator 7 and the vibration amplitude generated by the material flow. It can cope with the slight vibration during low-load operation of the device and also buffer the strong vibration during high-load operation, which greatly broadens the adaptability range of the vibration damping mechanism.

[0035] Please see Figures 1-5A U-shaped baffle 13 is provided at the top edge of the filter plate 3. The U-shaped baffle 13 can form a closed blocking structure at the edge of the filter plate 3. When the inclined filter plate 3 is driven by the vibrator 7 to perform separation operation, it can effectively prevent activated carbon particles from sliding from the edge of the filter plate 3 to the sand discharge area at the bottom of the sand removal box 1. This avoids material waste caused by the mixing of qualified activated carbon and sand, and also reduces the burden of subsequent separation treatment caused by activated carbon mixed in with impurities at the sand discharge port 10. By preventing material from falling off the edge, it can be ensured that all activated carbon can flow completely along the inclined direction of the filter plate 3 and fully pass through the screening process of the filter holes, avoiding the problem of insufficient screening caused by material falling off prematurely, and improving the stability of the sand removal effect.

[0036] Please see Figures 1-5 The bottom of the base plate 12 is equipped with multiple sets of adjusting screws 14. In actual installation environments such as workshops and factories, the ground may have slight bumps, depressions, or inclinations. By adjusting the extension length of the multiple sets of adjusting screws 14, the height of each support point of the base plate 12 can be adjusted individually, ensuring that the sand removal box 1 remains level at all times. This avoids problems such as deviations in the screening angle of the filter plate 3 and changes in the material flow direction caused by equipment tilting. If the equipment is not placed level, it will cause uneven force on the four sets of spring shock absorbers 11. Some shock absorbers may experience excessive pressure over a long period of time, leading to elastic fatigue and damage. The adjusting screws 14 ensure that the equipment is level, allowing the components of the shock absorption mechanism to bear force evenly, extending the service life of the shock absorbers, and indirectly ensuring the overall shock absorption effect of the device.

[0037] Please see Figures 1-5 Each of the four sets of adjusting screws 14 has a rubber pad 15 at its bottom. The rubber pad 15 has a high coefficient of friction, which increases the friction between the adjusting screw 14 and the ground, effectively preventing equipment slippage and ensuring the safety of production operations. The rubber pad 15 is soft and can form a buffer layer between the adjusting screw 14 and the ground. The rubber material itself has certain shock absorption and sound absorption properties, which can further absorb the vibration energy transmitted to the ground during the operation of the device, reducing the impact of vibration on the ground and surrounding equipment. At the same time, it can reduce the frictional noise generated by the vibration between the adjusting screw 14 and the ground, improving the workshop working environment.

[0038] In summary, when using this activated carbon sand removal device, the activated carbon to be sanded is poured into the device through the feed hopper 2 at the top of the sand removal box 1. The activated carbon first falls onto the inclined filter plate 3 of the upper screening mechanism. The vibrator 7 of the upper screening mechanism is activated, which drives the filter plate 3 to vibrate. At the same time, the inclined structure of the filter plate 3 guides the activated carbon to flow along the plate surface towards the discharge port 8 by gravity. During this process, larger particles in the activated carbon cannot pass through the aperture of the upper filter plate 3 and are retained on the filter plate 3 and discharged from the discharge port 8 with the flow trend; while smaller particles of activated carbon and sand fall through the aperture of the upper filter plate 3 and are accurately received by the guide hopper 9 at the bottom of the filter plate 3, and guided to the starting end of the filter plate 3 of the lower screening mechanism.

[0039] Smaller activated carbon particles and sand, guided by the feed hopper 9, fall onto the inclined filter plate 3 of the lower screening mechanism. The vibrator 7 of the lower screening mechanism is activated. Because the pores of the lower filter plate 3 are smaller, only sand can fall through the pores of the filter plate 3 to the bottom of the sand removal box 1, and finally be discharged from the sand discharge port 10 on the side of the bottom of the sand removal box 1 away from the discharge port 8. The smaller activated carbon particles that meet the particle size requirements are left on the lower filter plate 3 and flow with the inclined plate surface to the discharge port 8 for discharge, completing the secondary fine sand removal.

[0040] When the two-stage screening mechanism operates simultaneously, the shock absorption mechanism at the bottom of the sand removal box 1 works synchronously. Four sets of springs 6 cooperate with the shock absorption mechanism to absorb the vibration generated by the vibrator 7 and the impact energy brought by the material flow, reducing the overall vibration amplitude of the sand removal box 1 and avoiding structural fatigue and loosening of parts due to long-term vibration. The operator can continuously replenish the material to the feed hopper 2 according to the amount of activated carbon to be removed, and the device realizes continuous sand removal operation. The qualified activated carbon after screening is continuously discharged from the discharge port 8, and the separated sand is periodically cleaned from the sand discharge port 10.

[0041] This vibrator 7 is a commercially available device known to those skilled in the art. We are simply using it here without making any structural or functional improvements, which we will not elaborate on here. The vibrator 7 is equipped with a matching control switch, and the installation position of the control switch can be selected according to actual usage needs to facilitate operation and control by the operator.

[0042] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
