Description

Technical Field

[0001] This utility model relates to the field of coal slime screening and separation technology, and in particular to a vibrating inclined screen plate coal slime screening device. Background Technology

[0002] In coal processing, large pieces of coal are crushed into smaller particles using crushing equipment. This process is particularly important for coal slime, as it involves more than just simple crushing; it requires multi-stage processing to ensure the final particle size is appropriate, which helps improve subsequent combustion or processing efficiency. Because coal slime requires multi-stage crushing, only particles that meet the requirements will proceed to the next process; therefore, screening is an essential step. Existing screening devices mostly use vibrating screens, but because coal slime particles contain a certain amount of moisture and stickiness, the screen holes are easily clogged, leading to a significant decrease in screening efficiency. Cleaning the screens requires machine shutdown, thus existing devices present many inconveniences during screening. Utility Model Content

The height of both the arc-shaped baffles and the inclined baffles is greater than the height of the screen cylinder axis. Both the arc-shaped baffles and the inclined baffles cooperate with the surface of the screen cylinder. The arc-shaped baffles, the inclined baffles, the top surface of the screen cylinder, and the inner wall of the screening chamber form a storage cavity.

[0007] Both sides of the screening chamber are equipped with main rollers that cooperate with two slide rail beams.

[0010] Preferably, an elastic sealing layer is fixedly connected to the slide rod, and the elastic sealing layer is sealed to the inner wall of the auxiliary chamber.

[0015] The basic driving method of this device is the same as that of conventional screening devices, utilizing the rapid reciprocating motion of the screening chamber to screen coal slime particles. Its unique feature lies in combining the reciprocating motion of the screening chamber with a conventional reduction mechanism and a ratchet structure on the main roller, resulting in a slow rotation of the screen cylinder within the screening chamber. This slow rotation not only allows for switching between through-hole areas on the screen cylinder, but also, due to the screen cylinder's structural characteristics, enables coal slime particles to form a multi-layered dispersion on the screen cylinder surface, undergoing multiple screening processes during rotation. When a through-hole area on the screen cylinder becomes clogged, a new through-hole area immediately switches to the working position, thus avoiding frequent shutdowns for cleaning. Furthermore, the cleaning brushes in the auxiliary chamber dynamically clean the screen cylinder surface simultaneously during the reciprocating motion of the screening chamber, further reducing the possibility of screen clogging. In summary, this screening device, through the ingenious coordination of its mechanical structures, achieves efficient screening while significantly reducing cleaning frequency and simplifying cleaning operations, possessing high practicality and promotional value.

[0022] This utility model provides a vibrating inclined screen plate coal slime screening device, the structure of which is as follows: Figures 1 to 4 As shown, the invention includes a base 1, a drive housing 2, a screening chamber 3, an auxiliary chamber 8, and a grading assembly disposed inside the screening chamber 3. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0023] The base 1 serves as the fundamental support structure for the entire device. A drive housing 2 is fixedly connected to one side of its top, while a vertical plate is fixedly installed on the other side. The drive housing 2 and the vertical plate are connected by two spaced-apart slide rail beams, which guide and support the reciprocating movement of the screening chamber 3. The screening chamber 3 is located between the slide rail beams, with main rollers 7 on both sides. The main rollers 7 cooperate with the slide rail beams to achieve rolling motion. The main rollers 7 have a ratchet structure, allowing them to rotate only in one direction. One end of the screening chamber 3 is connected to the output end of the drive housing 2 via a crank-connecting rod mechanism. The drive housing 2 drives the screening chamber 3 to reciprocate on the slide rail beams via the crank-connecting rod mechanism. An inclined guide plate is also fixedly connected to the base 1, located at the bottom of the screening chamber 3, to guide the screened material to a designated position.

[0024] The screening chamber 3 is a hollow shell with open top and bottom, and a grading assembly is installed inside. The grading assembly includes a screen cylinder 4 rotatably mounted inside the screening chamber 3. The surface of the screen cylinder 4 has multiple evenly arranged through holes for screening coal slime particles. The grading assembly also includes two arc-shaped baffles 5 and two inclined baffles 6. The two arc-shaped baffles 5 are spaced apart along the axial direction of the screen cylinder 4 and fixedly connected to the inner walls of both sides of the screening chamber 3. The two inclined baffles 6 are spaced apart along the radial direction of the screen cylinder 4 and fixedly connected to the inner walls of both sides of the screening chamber 3. The height of both the arc-shaped baffles 5 and the inclined baffles 6 is greater than the height of the axis of the screen cylinder 4, and both fit into the surface of the screen cylinder 4. The arc-shaped baffles 5, the inclined baffles 6, the top surface of the screen cylinder 4, and the inner walls of the screening chamber 3 together form a storage cavity for temporarily storing the coal slime particles to be screened. A discharge door 18, which can be opened or closed, is provided on one side of the screening chamber 3 for discharging the screened qualified material.

[0025] The main roller 7 and the screen cylinder 4 are connected by a reduction gear mechanism, which is fixedly mounted on the outer surface of the screening chamber 3. When the screening chamber 3 reciprocates on the slide rail beam, the main roller 7 achieves unidirectional rotation through a ratchet structure, and transmits power to the screen cylinder 4 through the reduction gear mechanism, causing the screen cylinder 4 to rotate slowly. The slow rotation of the screen cylinder 4 can switch the through-hole areas on its surface, thereby avoiding the problem of decreased screening efficiency due to screen hole blockage.

[0026] An auxiliary chamber 8 is fixedly connected to the side of the screening chamber 3 away from the drive housing 2. Both sides of the auxiliary chamber 8 are equipped with rotatable secondary rollers, which cooperate with the slide rail beam to assist in the stable movement of the screening chamber 3. The auxiliary chamber 8, secondary rollers, main roller 7, and screen cylinder 4 are all in the same plane to ensure the overall structural coordination. A rectangular slot is provided at the joint between the screening chamber 3 and the auxiliary chamber 8. A vertically arranged guide column is fixedly connected inside the auxiliary chamber 8, and a horizontally arranged slide rod 10 is slidably connected to the guide column. A strip scraper 9 is fixedly connected to one end of the slide rod 10 near the rectangular slot. The strip scraper 9 is equipped with cleaning bristles for cleaning adhering substances from the surface of the screen cylinder 4. The other end of the slide rod 10 is connected to a double-end bracket, and pins are fixedly connected to both ends of the double-end bracket. A turntable 11 is provided on the inner walls of both sides of the auxiliary chamber 8. An elliptical track groove is provided on the turntable 11, and the pins are embedded in and cooperate with the elliptical track groove. When the screening chamber 3 moves back and forth, the auxiliary roller drives the turntable 11 to rotate through the transmission mechanism. The rotation of the turntable 11 causes the pin to move along the elliptical track groove, thereby pushing the slide bar 10 to slide back and forth on the guide column, causing the cleaning bristles on the strip scraper 9 to contact the surface of the screen cylinder 4 and dynamically clean it.

[0027] An elastic sealing layer 12 is fixedly connected to the slide rod 10. The elastic sealing layer 12 is sealed to the inner wall of the auxiliary chamber 8 and is located between the guide column and the strip scraper 9. The elastic sealing layer 12 divides the internal space of the auxiliary chamber 8 into a closed chamber. The double-end bracket and the turntable 11 are both located in the closed chamber to prevent external dust from entering the auxiliary chamber 8. Airflow channels are opened in both the strip scraper 9 and the slide rod 10. Multiple air outlets are provided on the side of the strip scraper 9 near the cleaning bristles. An exhaust pipe 14 connected to the airflow channel is fixedly connected to the double-end bracket. An air inlet pipe 13 is fixedly installed on the top of the auxiliary chamber 8. A dust cover is fixedly connected to the top of the air inlet pipe 13. One-way valves are provided on both the exhaust pipe 14 and the air inlet pipe 13. When the slide bar 10 moves back and forth, the gas in the airflow channel is discharged through the exhaust pipe 14, while outside air enters the airflow channel through the air inlet pipe 13, thereby forming a continuous airflow near the cleaning bristles of the strip scraper 9, further enhancing the cleaning effect on the surface of the screen cylinder 4.

[0028] A detection box 15 is fixedly connected to the side of the screening chamber 3 opposite to the rectangular slot. An industrial camera 16 is installed inside the detection box 15 for real-time monitoring of the working status of the screen cylinder 4. A transparent viewing window is fixedly provided at the joint between the detection box 15 and the screening chamber 3 so that the industrial camera 16 can clearly capture the surface of the screen cylinder 4. Electromagnetic clutches 17 are fixedly connected to both sides of the auxiliary chamber 8. The electromagnetic clutches 17 are used to control the transmission connection between the auxiliary roller and the turntable 11. When cleaning of the screen cylinder 4 is required, the electromagnetic clutches 17 are engaged, and the power of the auxiliary roller is transmitted to the turntable 11 through the electromagnetic clutches 17, thereby driving the strip scraper 9 to perform the cleaning operation; when cleaning is not required, the electromagnetic clutches 17 are disengaged, and the transmission between the auxiliary roller and the turntable 11 is cut off.

[0029] In practical applications, the device of this invention operates according to the following steps: First, the coal slime particles to be screened are fed into the storage chamber from the top of the screening chamber 3. The drive housing 2 drives the screening chamber 3 to reciprocate on the slide rail beam via a crank-connecting rod mechanism. The coal slime particles are vibrated in the storage chamber and screened through the through holes on the surface of the screen cylinder 4. During the screening process, the main roller 7 achieves unidirectional rotation through a ratchet structure and transmits power to the screen cylinder 4 through a reduction mechanism, causing the screen cylinder 4 to rotate slowly. The slow rotation of the screen cylinder 4 not only switches the through hole area on its surface but also allows the coal slime particles to form a multi-layered dispersion on the surface of the screen cylinder 4, thereby improving the screening efficiency. At the same time, the strip scraper 9 in the auxiliary chamber 8 dynamically cleans the surface of the screen cylinder 4 through the reciprocating movement of the slide rod 10, and the cleaning bristles contact the surface of the screen cylinder 4 to remove adhering substances. The airflow in the airflow channel is ejected through the air outlet to further enhance the cleaning effect. Industrial camera 16 monitors the working status of screen cylinder 4 in real time. When severe blockage of the screen holes is detected, electromagnetic clutch 17 is engaged, and the power of the auxiliary roller is transmitted to turntable 11, thereby enhancing the cleaning force of strip scraper 9. Qualified materials after screening are discharged through discharge gate 18, while materials that do not pass screening remain in storage chamber for further processing.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0031] In the initial stage of device operation, the coal slime particles to be screened are fed into the storage chamber from the top of the screening chamber 3. The storage chamber is enclosed by the arc-shaped baffle 5, the inclined baffle 6, the top surface of the screen cylinder 4, and the inner wall of the screening chamber 3, and its internal space can temporarily store a certain amount of coal slime particles. The drive housing 2 drives the screening chamber 3 to reciprocate along the slide rail beam through a crank-connecting rod mechanism. The main roller 7 cooperates with the slide rail beam to ensure that the movement of the screening chamber 3 is smooth and the force is uniform. During this process, the coal slime particles are subjected to vibration and gradually move closer to the through-hole area of ​​the screen cylinder 4. Particles that meet the particle size requirements pass through the through-holes into the lower space of the screening chamber 3, and are finally guided to the designated position by the inclined guide plate.

[0032] Meanwhile, the ratchet structure on the main roller 7 achieves unidirectional rotation during the reciprocating movement of the screening chamber 3, and transmits power to the screen cylinder 4 through the reduction mechanism. The slow rotation of the screen cylinder 4 causes the through-hole areas on its surface to switch continuously, thus avoiding the problem of decreased screening efficiency due to blockage in a certain area. In addition, the rotation of the screen cylinder 4 also enables the coal slime particles to form a multi-layered dispersion on its surface. When the coal slime particles rotate with the screen cylinder 4, the interaction force between the particles is weakened, and some particles adhering to the surface of the screen cylinder 4 will also detach due to centrifugal force, further improving the screening efficiency.

[0033] The strip scraper 9 inside the auxiliary chamber 8 dynamically cleans the surface of the screen cylinder 4 through the reciprocating movement of the slide rod 10. When the screening chamber 3 reciprocates, the auxiliary roller drives the turntable 11 to rotate through the transmission mechanism. The elliptical track groove on the turntable 11, in conjunction with the pin, pushes the slide rod 10 to slide back and forth along the guide column. The cleaning bristles on the strip scraper 9 contact the surface of the screen cylinder 4, removing coal slime particles adhering to the surface of the screen cylinder 4. The elastic sealing layer 12 is located between the guide column and the strip scraper 9, dividing the internal space of the auxiliary chamber 8 into a closed chamber to prevent external dust from entering the interior of the auxiliary chamber 8, while ensuring that the reciprocating movement of the slide rod 10 is not disturbed.

[0034] The airflow channels within the slide bar 10 and the strip scraper 9 further enhance the cleaning effect. As the slide bar 10 reciprocates, the gas in the airflow channels is discharged through the exhaust pipe 14, while outside air enters the airflow channels through the intake pipe 13. The airflow is ejected through the air outlet on the side of the strip scraper 9 closest to the cleaning bristles, creating a continuous airflow near the cleaning bristles and blowing away fine particles remaining on the surface of the sieve cylinder 4. The dust cover effectively prevents external dust from entering the airflow channels through the intake pipe 13, ensuring the stability of the cleaning process.

[0035] An industrial camera 16 inside the detection box 15 monitors the working status of the screen cylinder 4 in real time through a transparent window. When the industrial camera 16 detects severe blockage in the through-hole area on the surface of the screen cylinder 4, the electromagnetic clutch 17 is engaged, and the power of the auxiliary roller is transmitted to the turntable 11 through the electromagnetic clutch 17, thereby enhancing the cleaning force of the strip scraper 9. When the surface of the screen cylinder 4 is cleared, the electromagnetic clutch 17 is disengaged, the transmission between the auxiliary roller and the turntable 11 is cut off, and the strip scraper 9 stops high-intensity cleaning operation to save energy.

[0036] Qualified materials after screening are discharged through the discharge gate 18, while materials that fail screening remain in the storage chamber for further processing. Throughout the process, the reciprocating movement of the screening chamber 3, the slow rotation of the screen cylinder 4, the dynamic cleaning of the strip scraper 9, and the auxiliary cleaning function of the airflow channel work together to achieve the goals of efficient screening and automatic cleaning. The improved screening efficiency is attributed to the dynamic switching of the through-hole area of ​​the screen cylinder 4 and the multi-layered dispersion of coal slime particles, while the reduced cleaning frequency is due to the dual cleaning mechanism of the strip scraper 9 and the airflow channel. The organic combination of the above steps effectively solves the problem of screen clogging caused by moisture and stickiness of coal slime particles, significantly improving the practicality and promotional value of the device.
