A multi-functional coal slime separation centrifuge

Abstract

This utility model relates to the technical field of coal slime separation centrifuges, and in particular to a multi-functional coal slime separation centrifuge, comprising a base plate and a column. The top rear of the base plate is fixedly connected to the bottom of the column. A control structure is connected to the top of the column. A base is fixedly connected to the top front of the base plate. A housing is fixedly connected to the top of the base. A horizontal plate is fixedly connected to the left front of the housing. The speed increaser converts the low-speed, high-torque input shaft into a high-speed, low-torque output shaft. At this time, the shaft below the speed increaser drives the straight rod to rotate at high speed, which in turn drives the screen cylinder to rotate at high speed. The screen cylinder generates centrifugal force, causing the coal slime to be thrown against the inner wall of the screen cylinder. Particles in the coal slime larger than the screen cylinder's aperture cannot be discharged, while the moisture in the coal slime is discharged through the screen cylinder and thrown against the inner wall of the housing. This changes the original form of centrifugal force generation to avoid interference, ensuring the separation effect of the multi-functional coal slime separation centrifuge and ensuring its normal operation.

Description

Technical Field

[0001] This utility model relates to the technical field of multifunctional coal slime separation centrifuges, specifically a multifunctional coal slime separation centrifuge. Background Technology

[0002] The main function of a coal slime separation centrifuge is to use centrifugal force to quickly separate the water from the coal slime, thereby improving the dryness and processing efficiency of the coal slime.

[0003] For example, a multi-functional vertical coal slime centrifuge with announcement number "CN220004446U" includes a bell-shaped outer shell, a spiral scraper inside the outer shell, a screen basket fitted outside the spiral scraper, a feed inlet located directly above the outer shell, a distribution frustum located at the upper end of the spiral scraper, a differential transmission mechanism connecting the spiral scraper and the screen basket, and a drive mechanism. It has many advantages such as uniform feeding, stable operation, high unloading efficiency, low product moisture, reduced material density, and easy cleaning of sticky materials. However, in the use of this multi-functional coal slime centrifuge, the internal multi-scraper rotation method can affect the centrifugal force due to factors such as the large volume of the blades, the number of blades, and the shape of the blades. This can lead to insufficient rotation speed, affecting the centrifugal force and thus reducing the separation effect of the multi-functional coal slime centrifuge, affecting its normal use. Utility Model Content

[0004] The purpose of this invention is to solve the problem of reduced separation efficiency and impaired normal operation of multi-functional coal slime separation centrifuges, and to propose a multi-functional coal slime separation centrifuge.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multifunctional coal slime separation centrifuge is designed, including a base plate and a column. The top rear of the base plate is fixedly connected to the bottom of the column. A control structure is connected to the top of the column. A base is fixedly connected to the top front of the base plate. An outer shell is fixedly connected to the top of the base. A horizontal plate is fixedly connected to the left front of the outer shell. An opening and closing structure is connected to the inner side of the horizontal plate.

[0007] Preferably, the control structure includes a speed increaser and a straight rod. The bottom of the speed increaser is fixedly connected to the top of the column, the lower output shaft of the speed increaser is fixedly connected to the rear end face of the straight rod, a mesh cylinder is fixedly connected to the outer wall of the straight rod, and a servo motor is fixedly connected to the upper output shaft of the speed increaser.

[0008] Preferably, the rear side of the outer wall of the straight rod is rotatably connected to the rear end face of the outer casing, and the bottom of the servo motor is fixedly connected to the top of the outer casing.

[0009] Preferably, a vertical pipe is connected to the bottom front of the outer casing, and a second curved plate is fixed to the right front of the outer casing.

[0010] Preferably, the opening and closing structure includes a curved plate and a door panel. The outer wall of the curved plate is rotatably connected to the inner side of the horizontal plate. The right side of the curved plate is fixedly connected to the left side of the door panel. A first curved plate is fixedly connected to the right side of the door panel. A curved rod is threadedly connected to the inner wall of the first curved plate. The rear end face of the door panel is in contact with the front face of the outer shell.

[0011] Preferably, the outer wall of the curved rod is threaded to the inner wall of the second curved plate, and a curved pipe is connected to the upper front of the door panel.

[0012] The multifunctional coal slime separation centrifuge proposed in this utility model has the following advantages: When the servo motor in the control structure is powered on, the output of the servo motor transmits power to the shaft above the speed increaser. The speed increaser then converts the low-speed, high-torque input shaft into a high-speed, low-torque output shaft. At this time, the shaft below the speed increaser rotates at high speed with a straight rod, which in turn rotates the screen cylinder at high speed. The screen cylinder generates centrifugal force, causing the coal slime to be thrown against the inner wall of the screen cylinder. Particles in the coal slime larger than the screen cylinder's aperture cannot be discharged, while the moisture in the coal slime is discharged through the screen cylinder and thrown against the inner wall of the outer shell. This changes the original form of centrifugal force generation, avoiding any negative impact and ensuring the separation effect of the multifunctional coal slime separation centrifuge, thus guaranteeing its normal operation.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] Please see Figure 1-5 In this embodiment, a multifunctional coal slime separation centrifuge includes a base plate 1 and a column 4. The top rear of the base plate 1 is fixedly connected to the bottom of the column 4. A control structure 2 is connected to the top of the column 4. A base 6 is fixedly connected to the top front of the base plate 1. A shell 5 is fixedly connected to the top of the base 6. A horizontal plate 8 is fixedly connected to the left front of the shell 5. An opening and closing structure 3 is connected to the inner side of the horizontal plate 8.

[0022] The control structure 2 includes a speed increaser 201 and a straight rod 202. The bottom of the speed increaser 201 is fixedly connected to the top of the column 4. The model of the speed increaser 201 is selected according to the usage requirements. The lower output shaft of the speed increaser 201 is fixedly connected to the rear end face of the straight rod 202. A mesh tube 203 is fixedly connected to the outer wall of the straight rod 202. A servo motor 204 is fixedly connected to the upper output shaft of the speed increaser 201. The model of the servo motor 204 is selected according to the usage requirements. The rear of the outer wall of the straight rod 202 is rotatably connected to the rear end face of the outer shell 5. The straight rod 202 rotates under force through the sealed bearing on the rear end face of the outer shell 5. The bottom of the servo motor 204 is fixedly connected to the top of the outer shell 5.

[0023] By energizing the servo motor 204 in control structure 2, the servo motor output transmits power to the shaft above the speed increaser 201. The speed increaser 201 then converts the low-speed, high-torque input shaft into a high-speed, low-torque output shaft. At this time, the shaft below the speed increaser 201 drives the straight rod 202 to rotate at high speed, which in turn drives the screen cylinder 203 to rotate at high speed. The screen cylinder 203 generates centrifugal force, which causes the coal sludge to be thrown against the inner wall of the screen cylinder 203. Particles in the coal sludge that are larger than the aperture of the screen cylinder 203 cannot be discharged, while the moisture in the coal sludge is discharged through the screen cylinder 203 and thrown against the inner wall of the outer shell 5. This changes the original form of centrifugal force generation to avoid being affected, ensuring the separation effect of the multi-functional coal sludge separation centrifuge and ensuring its normal operation.

[0024] A vertical pipe 7 is connected to the bottom front of the outer casing 5. A second curved plate 12 is fixed to the right front of the outer casing 5. The opening and closing structure 3 includes a curved plate 301 and a door panel 302. The outer wall of the curved plate 301 is rotatably connected to the inner side of the horizontal plate 8. The curved plate 301 rotates under force through the inner pin of the horizontal plate 8. The right side of the curved plate 301 is fixed to the left side of the door panel 302. A first curved plate 303 is fixed to the right side of the door panel 302. A crank rod 304 is threadedly connected to the inner wall of the first curved plate 303. The crank rod 304, in conjunction with the outer wall thread, fixes the first curved plate 303 and the second curved plate 12. The rear end face of the door panel 302 is in contact with the front of the outer casing 5. The rear of the outer wall of the crank rod 304 is threadedly connected to the inner wall of the second curved plate 12. A curved pipe 11 is connected to the upper front of the door panel 302.

[0025] Working principle:

[0026] Multifunctional coal slime separation centrifuge operation:

[0027] The coal slurry is fed in through the bend 11 and then enters the mesh cylinder 203. The servo motor 204 is then powered on, transmitting power to the shaft above the speed increaser 201. The speed increaser 201 converts the low-speed, high-torque input shaft into a high-speed, low-torque output shaft. At this point, the shaft below the speed increaser 201 drives the straight rod 202 to rotate at high speed, which in turn drives the mesh cylinder 203 to rotate at high speed. This generates centrifugal force in the mesh cylinder 203, causing the coal slurry to be thrown against its inner wall. Particles in the coal slurry larger than the mesh cylinder 203's aperture cannot be discharged, while the water in the coal slurry is discharged through the mesh cylinder 203 and thrown against the inner wall of the outer casing 5. The water then flows downwards through the inner wall of the outer casing 5, which slopes from back to front, causing the water to flow out through the vertical pipe 7 and into a pre-placed water tank. This process achieves both coal slurry separation and water discharge, realizing multiple functions.

[0028] Cleaning of multi-functional coal slime separator centrifuge:

[0029] After the coal slime separation is completed, the crank rod 304, in conjunction with the outer wall thread, rotates forward through the first crank plate 303, causing the rear of the outer wall of the crank rod 304 to disengage from the second crank plate 12. Then, the door plate 302, in conjunction with the bent plate 301, rotates forward inside the straight plate 9, causing the door plate 302 to disengage from the front of the outer shell 5. Subsequently, the remaining coal slime inside the mesh cylinder 203 is cleaned, and the bent pipe 11 is rinsed. After completion, the door plate 302 is rotated back to fit against the front of the outer shell 5. Then, the crank rod 304, in conjunction with the thread, rotates backward through the first crank plate 303, causing the rear of the outer wall of the crank rod 304 to connect with the inner wall thread of the second crank plate 12, completing the closure of the door plate 302 (the contact points between the door plate 302 and the outer shell 5 and the mesh cylinder 203 are all connected with sealing rings, and after closure, the door plate 302 forms a seal with the mesh cylinder 203 and the outer shell 5).

[0030] Example 2:

[0031] Please see Figure 1-5 In this embodiment, a multifunctional coal slime separation centrifuge further includes straight plates 9 and rollers 10. The inner sides of multiple straight plates 9 are fixedly connected to the front of the outer wall of the mesh cylinder 203, and the rear end face of the straight plates 9 is rotatably connected to the outer wall pin of the rollers 10.

[0032] Working principle:

[0033] When the mesh cylinder 203 rotates, it will cause the straight plate 9 to rotate as well. The rotating straight plate 9, along with the roller 10, rotates against the inner wall of the outer shell 5. The straight plate 9 and the roller 10 together provide support for the mesh cylinder 203.

[0034] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
