Description

Technical Field

[0001] This utility model relates to the field of activated carbon technology, and in particular to an activated carbon screening 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. Then, they react with gases, and the surface is eroded, creating a structure with well-developed micropores.

[0003] Chinese patent discloses an activated carbon screening device (authorization announcement number CN219790576U). This patented technology achieves the purpose of facilitating the positioning of the storage bag by setting a positioning shell and a threaded tube. At the same time, the storage bag can be quickly separated from the positioning shell when it is taken out. By setting a receiving box, a guide plate and a discharge pipe, the two discharge pipes can be used to discharge materials alternately. Therefore, the storage bag can be replaced without stopping the equipment, which effectively improves the screening efficiency of the equipment. The structure is simple and the operation is convenient.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: During the screening process of activated carbon, a certain amount of dust is generated, and the existing screening devices lack effective dust interception measures. This dust may escape into the air. Activated carbon dust not only reduces the cleanliness of the working environment, but may also pose a threat to the health of workers, because it can be inhaled into the respiratory tract, thereby affecting lung health. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology lacks measures to intercept activated carbon dust. To address this, we propose an activated carbon screening device.

[0006] To achieve the above objectives, this application adopts the following technical solution: an activated carbon screening device, including a base, a collection bin installed on the top of the base, an installation groove opened on the top of the collection bin, a filter screen installed on the top of the installation groove, a dust cover installed on the top of the filter screen, and a feed inlet opened on the top of the dust cover.

[0007] The top of the dust cover is equipped with a shielding mechanism for blocking the feed inlet.

[0008] Both sides of the filter screen are equipped with clamping mechanisms for securing the dust cover.

[0009] Preferably, the shielding mechanism includes a first magnetic sheet installed on the top of the dust cover, a second magnetic sheet disposed on the top of the first magnetic sheet, and a baffle fixedly connected to the top of the second magnetic sheet.

[0010] Preferably, the clamping mechanism includes four extension rods fixedly connected to both sides of the filter screen. A rotating shaft is fixedly connected to the opposing surfaces of the extension rods. A C-shaped clamping plate that cooperates with the dust cover is rotatably connected to the surface of the rotating shaft. Fastening components for fixing the C-shaped clamping plate are installed on both sides of the dust cover.

[0011] Preferably, the fastening assembly includes a slide rod fixedly connected to both sides of the dust cover, a locking block rotatably connected to the surface of the slide rod, a through groove on one side of the C-shaped locking plate, a locking slot for cooperating with the locking block on the side of the C-shaped locking plate away from the dust cover, a limiting plate fixedly connected to one end of the slide rod, a spring sleeved on the surface of the slide rod, one end of the spring fixedly connected to the locking block, and the other end of the spring fixedly connected to the limiting plate.

[0012] Preferably, a handle is installed on the top of the baffle.

[0013] Preferably, a discharge pipe is installed on one side of the collection bin.

[0014] Preferably, the mounting groove is equipped with a buffer pad for use with the filter screen.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In this invention, after the user installs the filter screen on top of the base, the dust cover is then installed on top of the filter screen. Through the combined use of the shielding mechanism on top of the dust cover and the dust cover itself, the dust generated by the activated carbon during the screening process can be effectively prevented from escaping, thereby ensuring the cleanliness of the working environment, reducing the impact on workers' health, and protecting their lung health.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figures 1-5 As shown, this utility model provides a technical solution: an activated carbon sieving device, including a base 1, a collection bin 2 installed on the top of the base 1, an installation groove 3 opened on the top of the collection bin 2, a filter screen 4 installed on the top of the installation groove 3, a dust cover 5 installed on the top of the filter screen 4, a feed inlet 6 opened on the top of the dust cover 5, a blocking mechanism for blocking the feed inlet 6 installed on the top of the dust cover 5, and clamping mechanisms for locking the dust cover 5 installed on both sides of the filter screen 4. A discharge pipe 11 is installed on one side of the collection bin 2. After the user installs the filter screen 4 on the top of the base 1, the dust cover 5 is then installed on top of the filter screen 4. The dust cover 5 is secured to the top of the filter screen 4 by a clamping mechanism. Activated carbon is then poured into the filter screen 4 through the feed inlet 6. The feed inlet 6 is then blocked by a shielding mechanism to prevent dust generated by the activated carbon from escaping during the screening process, thus ensuring the cleanliness of the working environment, reducing the impact on workers' health and protecting their lung health. During the filtration process, the filter screen 4 intercepts qualified particles, while excessively fine particles pass through the filter screen 4 and enter the collection chamber 2. The discharge pipe 11 ensures that the fine particles entering the collection chamber 2 are discharged uniformly.

[0025] Reference Figure 3 As shown in this embodiment, the shielding mechanism includes a first magnetic sheet 7 installed on the top of the dust cover 5, a second magnetic sheet 9 disposed on the top of the first magnetic sheet 7, a baffle 8 fixedly connected to the top of the second magnetic sheet 9, and a handle 10 installed on the top of the baffle 8. Through the magnetism between the second magnetic sheet 9 and the first magnetic sheet 7, the baffle 8 is attracted to the top of the dust cover 5, thereby shielding the feed inlet 6. At the same time, the handle 10 allows the user to quickly remove the baffle 8, making the overall operation relatively simple.

[0026] Reference Figure 3 and Figure 4As shown in this embodiment: the clamping mechanism includes four extension rods 13 fixedly connected to both sides of the filter screen 4. A rotating shaft 14 is fixedly connected to the facing surfaces of the extension rods 13. A C-shaped clamping plate 15 for use with the dust cover 5 is rotatably connected to the surface of the rotating shaft 14. Fastening components for fixing the C-shaped clamping plate 15 are installed on both sides of the dust cover 5. After the dust cover 5 is installed on the top of the filter screen 4, the C-shaped clamping plate 15 is rotated to clamp the dust cover 5. With the fastening components, the position of the C-shaped clamping plate 15 is fixed, thereby fixing the position of the dust cover 5 and preventing the dust cover 5 from falling off when the equipment is started.

[0027] Reference Figure 5 As shown in this embodiment: the fastening assembly includes a slide rod 16 fixedly connected to both sides of the dust cover 5. A locking block 17 is rotatably connected to the surface of the slide rod 16. A through groove 18 is opened on one side of the C-shaped locking plate 15, and a locking groove 19 that cooperates with the locking block 17 is opened on the side of the C-shaped locking plate 15 away from the dust cover 5. A limiting plate 20 is fixedly connected to one end of the slide rod 16. A spring 21 is sleeved on the surface of the slide rod 16. One end of the spring 21 is fixedly connected to the locking block 17, and the other end of the spring 21 is connected to the limiting plate. 20. For fixed connection, when the C-shaped clamping plate 15 is rotated to clamp the dust cover 5, the clamping block 17 is rotated to a vertical position so that the clamping block 17 can pass through the through slot 18. After the C-shaped clamping plate 15 clamps the dust cover 5, the clamping block 17 is rotated to insert into the slot 19. Through the cooperation with the spring 21, the position of the clamping block 17 is restricted to the inside of the slot 19, thereby fixing the position of the C-shaped clamping plate 15 and preventing the C-shaped clamping plate 15 from rotating on its own.

[0028] Reference Figure 2 As shown in this embodiment: The installation groove 3 is equipped with a buffer pad 12 that works with the filter screen 4. The buffer pad 12 acts as a buffer at the connection between the collection chamber 2 and the filter screen 4, thereby reducing the collision between the filter screen 4 and the collection chamber 2 and extending the service life.

[0029] Working Principle: After the user installs the filter screen 4 on top of the base 1, the dust cover 5 is then installed on top of the filter screen 4. The dust cover 5 is then secured in place by a clamping mechanism. Activated carbon is then poured into the filter screen 4 through the feed inlet 6. The feed inlet 6 is then blocked by a shielding mechanism to prevent dust generated by the activated carbon from escaping during the sieving process, thus ensuring a clean working environment and reducing the impact on worker health, protecting lung health. During filtration, the filter screen 4 intercepts qualified particles, while excessively fine particles pass through and enter the collection chamber 2. The discharge pipe 11 ensures that the fine particles entering the collection chamber 2 are discharged uniformly. The magnetic field between the second magnetic plate 9 and the first magnetic plate 7 causes the baffle 8 to adhere to the top of the dust cover 5, thereby blocking the feed inlet 6. The baffle 8 serves as a shield, and the handle 10 allows users to quickly remove it. The overall operation is simple. After the dust cover 5 is installed on top of the filter screen 4, the C-shaped clamp 15 is rotated to lock the dust cover 5 in place. The fastening components further secure the C-shaped clamp 15, preventing it from falling off during equipment startup. When the C-shaped clamp 15 is rotated to lock the dust cover 5, the locking block 17 is rotated to a vertical position, allowing it to pass through the through slot 18. After the C-shaped clamp 15 locks the dust cover 5, the locking block 17 is rotated into the slot 19. The spring 21 further restricts the position of the locking block 17 within the slot 19, thus fixing the position of the C-shaped clamp 15 and preventing it from rotating on its own.
