Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, specifically a grinding equipment for activated carbon processing. Background Technology

[0002] Activated carbon is a porous carbonaceous material with a highly developed pore structure and a large specific surface area, giving it extremely strong adsorption capacity. It is typically produced by reacting carbonaceous materials with gases or activating agents at high temperatures, a process that increases the number of micropores and mesopores within the carbon. Due to its excellent adsorption properties, activated carbon has wide applications in various fields. In water treatment, it effectively removes impurities, residual chlorine, heavy metal ions, and organic pollutants from water, improving water quality. In air purification, activated carbon adsorbs harmful gases, odors, and fine particulate matter from the air, improving indoor air quality.

[0003] In the processing of activated carbon, the carbonaceous raw material must first be ground into fine powder using a grinding mill. This process is crucial because the particle size of the powder directly affects the effectiveness of subsequent activation treatment. To ensure the quality of activated carbon, the particle size of the ground powder needs to be controlled below 150 micrometers. However, most grinding mills on the market currently lack effective screening functions, which means that some substandard particles may be mixed into the carbon powder produced during the grinding process. If these substandard carbon particles are mixed into the powder without being screened, they will seriously affect the quality and performance of the final processed activated carbon. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for activated carbon processing, so as to solve the problem that existing grinding mills cannot perform screening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a positioning base, on which a motor and a grinding mill body are fixedly mounted. A feed funnel is fixedly mounted on the upper end of the grinding mill body, and a discharge port is fixedly mounted on the lower end of the grinding mill body. A screening mechanism is connected to the discharge port. The screening mechanism includes a mechanism housing fixedly mounted on the positioning base, a positioning frame movably mounted inside the mechanism housing, a screen fixedly mounted on the positioning frame, and a connecting leg fixedly mounted at the bottom of the positioning frame. A feed port is opened at the upper end of the mechanism housing, and a drive mechanism is connected to the connecting leg.

[0006] Preferably, a first discharge port is provided at the bottom of the outer casing of the mechanism, and a second discharge port is provided on one side of the outer casing of the mechanism.

[0007] Preferably, the bottom of the outer casing of the mechanism is provided with bolts, and the outer casing of the mechanism is fixedly installed on the positioning base by bolts.

[0008] Preferably, the discharge port is connected to the housing of the mechanism via the inlet, and a portion of the positioning frame extends out of the housing of the mechanism via the second discharge port.

[0009] Preferably, the drive mechanism includes a positioning housing fixedly mounted on the outer shell of the mechanism. A telescopic rod is slidably mounted on one end of the positioning housing, and a movable shaft is rotatably mounted on the other end of the positioning housing. One end of the telescopic rod is fixedly mounted on a connecting support leg, and a telescopic sleeve is fixedly mounted on the other end of the telescopic rod. The telescopic sleeve is provided with a sliding support leg. A rotating seat is fixedly mounted on one end of the movable shaft, and a reciprocating groove is provided on the rotating seat. A horizontal transmission shaft is fixedly mounted on the other end of the movable shaft. A vertical transmission shaft is fixedly mounted on the output end of the motor. Helical gears are fixedly mounted on both the vertical transmission shaft and the horizontal transmission shaft, and the two sets of helical gears mesh together.

[0010] Preferably, the positioning base is provided with a retainer, and the horizontal drive shaft is rotatably mounted on the positioning base through the retainer.

[0011] Preferably, the sliding support is slidably mounted on the rotating seat via a reciprocating groove, the telescopic sleeve is slidably mounted in the positioning housing via a telescopic rod, and the rotating seat is rotatably mounted in the positioning housing via a movable shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, the raw material powder after grinding will be discharged through the discharge port. After the powder falls onto the screen, the reciprocating motion of the telescopic rod will drive the positioning frame on the connected support to move back and forth accordingly. The reciprocating motion of the positioning frame will further drive the screen to move back and forth synchronously, so as to achieve effective screening of the powder on the screen.

[0014] 2. In this application, the electric motor drives the vertical transmission shaft to rotate, which in turn causes the horizontal transmission shaft to rotate. The rotation of the horizontal transmission shaft will cause the movable shaft to rotate, and the rotation of the movable shaft will drive the rotating seat to rotate. During the rotation of the rotating seat, the sliding support slides along the reciprocating groove. The reciprocating sliding of the sliding support will drive the telescopic sleeve to perform back-and-forth reciprocating motion. The reciprocating motion of the telescopic sleeve will further drive the telescopic rod to perform corresponding back-and-forth reciprocating motion, ultimately realizing the operation of the grinding mill body and screening mechanism driven by the electric motor.

[0020] 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.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a grinding device for activated carbon processing, including a positioning base 1, on which a motor 2 and a grinding mill body 4 are fixedly installed. A feed funnel 3 is fixedly installed at the upper end of the grinding mill body 4, and a discharge port 5 is fixedly installed at the lower end of the grinding mill body 4. A screening mechanism 6 is connected to the discharge port 5, and a drive mechanism 7 is connected to the connecting support 604. Through the cooperation of the drive mechanism 7 and the screening mechanism 6, the ground powder can be screened to improve the grinding quality.

[0022] like Figure 2 and Figure 3 As shown, the screening mechanism 6 includes a mechanism housing 601 fixedly installed on the positioning base 1. A positioning frame 606 is movably installed inside the mechanism housing 601. A screen 603 is fixedly installed on the positioning frame 606. A connecting support leg 604 is fixedly installed at the bottom of the positioning frame 606. A feed inlet 602 is opened at the upper end of the mechanism housing 601. A first discharge port 605 is opened at the bottom of the mechanism housing 601. A second discharge port 607 is opened on one side of the mechanism housing 601. Bolts are provided at the bottom of the mechanism housing 601. The mechanism housing 601 is fixedly installed on the positioning base 1 by bolts.

[0023] Specifically, after the raw materials are finely ground, the fine powder is discharged through a specific outlet 5. The discharged powder then falls onto a screen 603. Below the screen 603, there is a telescopic rod 701 that performs a reciprocating motion. When the telescopic rod 701 performs this reciprocating motion, it drives the positioning frame 606 on the connecting support 604 to also perform a corresponding reciprocating motion. During the movement of the positioning frame 606, it further causes the screen 603 to also perform a reciprocating motion. This effectively screens the powder, ensuring that it meets the required particle size standards.

[0024] like Figure 2 and Figure 4 As shown, the drive mechanism 7 includes a positioning housing 702 fixedly mounted on the outer shell 601. A telescopic rod 701 is slidably mounted on one end of the positioning housing 702, and a movable shaft 707 is rotatably mounted on the other end of the positioning housing 702. One end of the telescopic rod 701 is fixedly mounted on a connecting support 604, and a telescopic sleeve 703 is fixedly mounted on the other end of the telescopic rod 701. A sliding support 704 is provided on the telescopic sleeve 703. A rotating seat 705 is fixedly mounted on one end of the movable shaft 707. A reciprocating groove 706 is provided on the rotating seat 705. A horizontal transmission shaft 708 is fixedly mounted on the other end of the movable shaft 707. A vertical transmission shaft 709 is fixedly mounted on the output end of the motor 2. Helical gears 710 are fixedly mounted on both the vertical transmission shaft 709 and the horizontal transmission shaft 708, and the two sets of helical gears 710 mesh together.

[0025] Specifically, motor 2 has driving capability, effectively causing the vertical drive shaft 709 to rotate. As the vertical drive shaft 709 rotates, it further causes the horizontal drive shaft 708 to rotate. The rotation of the horizontal drive shaft 708 then triggers the rotation of the movable shaft 707. Once the movable shaft 707 begins to rotate, it drives the rotating seat 705 to rotate. During the rotation of the rotating seat 705, the sliding support 704 slides along the reciprocating groove 706. The sliding of the sliding support 704 in the reciprocating groove 706 further causes the telescopic sleeve 703 to reciprocate back and forth. When the telescopic sleeve 703 reciprocates, it drives the telescopic rod 701 to also reciprocate back and forth. Through this transmission chain, motor 2 successfully drives the grinding mill body 4 and the screening mechanism 6.

[0026] Working Principle: During operation, the raw material is first fed into the feed hopper 3. After the raw material is fed into the feed hopper 3, the motor 2 can be started. Starting the motor 2 will drive the grinding mill body 4 to operate, thereby grinding the raw material into fine powder. After the raw material is ground into fine powder, it will be discharged through the discharge port 5. The powder discharged through the discharge port 5 will fall onto the screen 603. At this time, the motor 2 can drive the vertical drive shaft 709 to rotate. After the vertical drive shaft 709 rotates, it will drive the horizontal drive shaft 708 to rotate. After the horizontal drive shaft 708 rotates, the movable shaft 707 will rotate. The movable shaft 707 will then drive... When the rotating seat 705 rotates, the sliding support 704 slides along the reciprocating groove 706. When the sliding support 704 slides along the reciprocating groove 706, it drives the telescopic sleeve 703 to reciprocate back and forth. When the telescopic sleeve 703 reciprocates back and forth, it drives the telescopic rod 701 to reciprocate back and forth. When the telescopic rod 701 reciprocates back and forth, it drives the positioning frame 606 connected to the support 604 to reciprocate back and forth. When the positioning frame 606 reciprocates back and forth, it drives the screen 603 to reciprocate back and forth, thereby screening the powder that falls onto the screen 603.

[0027] 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.
