Description

Technical Field

[0001] This utility model relates to the field of can-making equipment technology, and in particular to a centrifugal separation device with automatic slag discharge. Background Technology

[0002] In typical centrifugal filtration systems, as the centrifugation process continues, solid impurities in the liquid are trapped on the centrifugal element, i.e., the filter cartridge. Over time, this causes an increase in pressure and centrifugal resistance, leading to a decrease in filtration efficiency. At this point, it is generally necessary to interrupt the centrifugation operation, replace the centrifugal element, or remove it for cleaning, which is both time-consuming and labor-intensive, impacting processing efficiency.

The cleaning installation mechanism includes a fixed frame, a movable rod, and a cleaning drive assembly. The fixed frame is disposed inside the device barrel and fixedly connected to the top of the device barrel.

[0006] Optionally, the device barrel is provided with a slag discharge port at the bottom; a slag collection barrel is provided on the mounting frame, located below the slag discharge port; the bottom of the centrifuge barrel is a conical slope, and multiple slag discharge holes are provided on the western side of the conical slope.

[0007] Optionally, the centrifugal drive assembly includes a first bevel gear, a second bevel gear, and a centrifugal motor; the first bevel gear is rotatably sleeved on the movable rod and rotatably installed in the through hole, and fixedly connected to the bottom of the centrifugal drum; the centrifugal motor is fixedly installed on the mounting bracket; the second bevel gear is installed on the output shaft of the centrifugal motor and meshes with the first bevel gear.

[0011] In this invention's automatic slag discharge centrifugal separation device, a fixed frame is fixedly connected to the cover for mounting a movable rod and a cleaning mechanism. The movable rod, along with two linkage rods and a cleaning rod, forms a parallelogram mechanism, and the linkage rods are rotatably mounted on the fixed frame, forming a lever mechanism with the fixed frame. In the initial state, the two linkage rods are tilted downwards as follows: Figure 1 As shown, when the movable rod moves downwards, the two linkage rods, under the action of the lever mechanism and the parallelogram mechanism, drive the cleaning rod to move closer to the inner wall of the centrifuge tank.

[0018] Figure 1 This is a schematic structural diagram of a centrifugal separation device with automatic slag discharge, such as... Figure 1 As shown, and with reference Figure 2 The automatic slag discharge centrifugal separation device includes a mounting frame 100, a device barrel 200, a centrifugal mechanism, a cleaning and mounting mechanism, and multiple cleaning mechanisms 500. The device barrel 200 is fixedly mounted on the mounting frame 100, and the top of the device barrel 200 is provided with a feed inlet 220.

[0019] The centrifugation mechanism includes a centrifuge tank 300 and a centrifugation drive assembly. The centrifuge tank 300 is rotatably mounted inside the device tank 200, and the inner walls of the centrifuge tank 300 and the device tank 200 are fitted with a clearance. The bottom of the device tank 200 has a discharge port 230 communicating with the clearance, and the bottom axis of the centrifuge tank 300 has a through hole extending downward through the bottom of the device tank 200. The centrifugation drive assembly is used to drive the centrifuge tank 300 to rotate.

[0020] The cleaning installation mechanism includes a fixed frame 410, a movable rod 420, and a cleaning drive assembly. The fixed frame 410 is disposed inside the device barrel 200 and fixedly connected to the top of the device barrel 200. The movable rod 420 is inserted into a through hole and slidably disposed within the fixed frame 410. The cleaning drive assembly is used to drive the movable rod 420 to reciprocate up and down. Multiple cleaning mechanisms 500 are evenly distributed around the movable rod 420. Each cleaning mechanism includes two linkage rods 510 and a sweeping rod 520. The two linkage rods 510 are rotatably mounted on the fixed frame 410, and the inner ends of the linkage rods 510 are hinged to the movable rod 420. The sweeping rod 520 is vertically disposed and hinged to the outer ends of the two linkage rods 510.

[0021] Specifically, the top of the device barrel 200 is a removable cover 210, and the feed inlet 220 is provided on the cover 210 for introducing material into the centrifuge barrel 300 inside the device barrel 200. Furthermore, the peripheral wall of the centrifuge barrel 300 is sieve-like, and the gap fit between the centrifuge barrel 300 and the device barrel 200 allows for the reception of filtered material separated by centrifugation. The discharge port 230 allows for the discharge of the filtered material stored between the centrifuge barrel 300 and the device barrel 200.

[0022] Furthermore, the fixed frame 410 is fixedly connected to the cover 210 for mounting the movable rod 420 and the cleaning mechanism 500. The movable rod 420, together with two linkage rods 510 and a cleaning rod 520, forms a parallelogram mechanism, and the linkage rods 510 are rotatably mounted on the fixed frame 410, forming a lever mechanism with the fixed frame 410. In the initial state, the two linkage rods 510 are tilted downwards as shown... Figure 1 As shown, when the movable rod 420 moves downward, the two linkage rods 510, under the action of the lever mechanism and the parallelogram mechanism, drive the cleaning rod 520 to move towards the inner wall of the centrifuge tank 300. When the movable rod 420 moves to the lowest point, the linkage rod 510 moves to a horizontal state, and the cleaning rod 520 contacts the inner wall of the centrifuge tank 300. Since the centrifuge tank 300 is in a continuous rotating state, the relative movement between the cleaning rod 520 and the centrifuge tank 300 can clean the inner wall of the centrifuge tank 300, thereby preventing the inner wall of the centrifuge tank 300 from becoming clogged. Furthermore, because the cleaning drive assembly drives the movable rod 420 to continuously reciprocate up and down, the cleaning rod 520 can clean the inner wall of the centrifuge tank 300 while the centrifuge tank 300 is in operation, thus ensuring the working efficiency and filtration effect of the centrifuge tank 300 and avoiding the need to stop for cleaning due to clogging of the centrifuge tank 300, thereby greatly improving working efficiency.

[0023] Meanwhile, the reciprocating inward and outward movement of the cleaning rod 520 agitates the material, preventing it from accumulating inside the centrifuge tank 300 and improving centrifugal separation efficiency. The reciprocating movement of the cleaning rod 520 also prevents excessive contact between the cleaning rod 520 and the inner wall of the centrifuge tank 300, thus preventing rapid wear and extending the service life of the cleaning rod 520.

[0024] During operation, the cleaning drive assembly and the centrifugal drive assembly are activated. The centrifugal drive assembly drives the centrifuge drum 300 to rotate at high speed, while the cleaning drive assembly drives the movable rod 420 to reciprocate up and down. Material is introduced into the centrifuge drum 300 through the feed inlet 220. Driven by the high-speed rotation of the centrifuge drum 300, the material undergoes centrifugal separation. The centrifuged and filtered material enters the gap between the centrifuge drum 300 and the device drum 200, and is discharged outwards through the discharge outlet 230. Simultaneously, the movable rod 420 moves downwards, and through the setting of the fixed frame 410 and the linkage rod 510, it drives the cleaning rod 520 to move outwards until it contacts the inner wall of the centrifuge drum 300. During the high-speed rotation of the centrifuge drum 300, the cleaning rod 520 cleans the inner wall of the centrifuge drum 300. The movable rod 420 moves upwards, causing the cleaning rod 520 to retract inwards and move away from the inner wall of the centrifuge drum 300.

[0025] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cleaning mechanism 500 also includes two hinge seats 530, a stirring rod 540, and multiple stirring blades 550. Each hinge seat 530 is hinged to a linkage rod 510, and the stirring rod 540 is vertically arranged between the two linkage rods 510, with both its upper and lower ends rotatably connected to the hinge seat 530. The multiple stirring blades 550 are fixedly mounted on the stirring rod 540.

[0026] Specifically, the stirring rod 540 is rotatably mounted between two linkage rods 510, enabling it to move synchronously in and out with the linkage rods 510, driving the stirring rod 540 and the cleaning rod 520. The stirring blades 550 increase the contact area between the stirring rod 540 and the material. Simultaneously, as the material rotates with the centrifuge tank 300, contacting the stirring blades 550 generates a rotational force on them, which in turn drives the stirring rod 540 and the stirring blades 550 to rotate, further increasing the stirring efficiency of the material.

[0027] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the device has a slag discharge port 240 at the bottom of the tank. A slag collection bucket 110 is mounted on the mounting frame 100, located below the slag discharge port 240. The bottom of the centrifuge tank 300 is a conical slope, and multiple slag discharge holes 340 are provided on the western side of the conical slope. An electrically controlled valve 241 is installed inside the slag discharge port 240.

[0028] Specifically, the discharge port 240 is used to discharge the filter residue at the bottom of the centrifuge tank 300 to the collection tank 110 for collection. Furthermore, the conical slope of the centrifuge tank 300's surface allows the filter residue to be smoothly discharged to the discharge hole 340. Multiple discharge holes 340 can discharge filter residue from multiple different locations within the centrifuge tank 300. Whenever the discharge hole 340 rotates to be coaxial with the discharge port 240, the filter residue is discharged from the discharge port 240 into the collection tank 110. The electrically controlled valve 241 is used to open when the centrifuge tank 300 needs to discharge residue.

[0029] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the centrifugal drive assembly includes a first bevel gear 310, a second bevel gear 320, and a centrifugal motor 330. The first bevel gear 310 is rotatably sleeved on the movable rod 420 and rotatably installed in the through hole, fixedly connected to the bottom of the centrifuge tank 300. The centrifugal motor 330 is fixedly installed on the mounting bracket 100. The second bevel gear 320 is installed on the output shaft of the centrifugal motor 330 and meshes with the first bevel gear 310.

[0030] Specifically, the centrifugal motor 330 drives the second bevel gear 320 to rotate, and the second bevel gear 320 drives the centrifugal drum 300 to rotate.

[0031] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cleaning drive assembly includes a drive rod 430, a drive disc 440, and a cleaning motor 450. The cleaning motor 450 is fixedly mounted on the mounting bracket 100. The drive disc 440 is fixedly mounted on the drive shaft of the cleaning motor 450. One end of the drive rod 430 is rotatably connected to the lower end of the movable rod 420, and the other end is rotatably connected to the eccentric position of the drive disc 440.

[0032] Specifically, the drive rod 430, drive disc 440 and movable rod 420 constitute a crank-connecting rod mechanism. When the drive disc 440 rotates, it drives the movable rod 420 to move up and down reciprocally through the drive rod 430.

[0033] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cleaning rod 520 is equipped with a brush 521 on one side of the inner wall of the centrifuge tank 300. Specifically, the brush 521 can increase the cleaning effect on the inner wall of the centrifuge tank 300.

[0034] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the stirring blade 550 is in the shape of a spiral auger blade, with the spiral directions of two adjacent stirring blades 550 being opposite. Specifically, the auger blade configuration of the stirring blade 550 enables the material to be rotated and stirred during the rotation of the stirring blade 550. The opposite spiral configuration of two adjacent stirring blades 550 can avoid uneven stirring caused by the material rotating on only one side, thereby further increasing the stirring efficiency.

[0035] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
