Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of industrial application of thickeners, and in particular, to a thickener. Background Art

[0002] A large amount of slurry is bound to be produced in the processes of mineral processing, metallurgy, chemical industry, water treatment, environmental protection, etc. The thickening of slurry is currently the most common method for processing slurry, and the thickener is the core equipment of the entire thickening process. When the thickener is working, the underflow material needs to be discharged in time to avoid excessive concentration or compaction of the underflow material. If the underflow material concentration of the thickener is too high or the underflow material is not discharged in time, the material will accumulate around the rake frame, causing the rotation pressure of the rake frame to exceed the working pressure of the thickener transmission system, thereby causing the thickener rake frame to stop rotating and a rake compression accident to occur. In view of the above reasons, it is necessary to discharge the underflow material of the thickener in time and reduce the concentration of the underflow material to ensure that the thickener does not compress the rake; or after the thickener has a rake compression accident, the material around the thickener rake frame is fully discharged, and the pressure around the rake frame is reduced to the operating pressure, and the rake frame can continue to operate, thereby ensuring the normal operation of the thickener and saving time and cost for cleaning the thickening tank.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] In order to make the technical problems, technical solutions and advantages to be solved by this embodiment clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0043] like Figure 1 and Figure 2 As shown, the thickener provided in this embodiment includes a tank body 4, a main shaft 7 disposed in the tank body 4, a rake frame disposed in the tank body 4, and a vibration mechanism installed on the rake frame. The rake frame is connected to the main shaft 7, and the main shaft 7 can rotate under the drive of the driving mechanism, and the rake frame can rotate with the main shaft 7, that is, the driving mechanism can drive the main shaft 7 to rotate, and the main shaft 7 rotates, thereby driving the rake frame to rotate.

[0044] In this embodiment, the vibration mechanism includes a vibration component 1 and a driving member 5. The vibration component 1 is connected to the rake frame. The driving member 5 drives the vibration component 1 to vibrate. The vibration component 1 drives the rake frame to vibrate. The vibration of the rake frame causes the high-concentration materials on the rake frame and its surroundings to vibrate. Under the action of vibration force and gravity, the high-concentration materials at the bottom of the tank body 4 can be easily discharged, preventing the thickener from being pressed and raked due to excessive concentration of underflow materials and material accumulation, so that the thickener can operate efficiently. The thickener provided in the embodiment of the present application operates more efficiently and has a low failure rate. Compared with the traditional thickener method of manually cleaning the tank body 4 after pressing and raking, it saves a lot of time and financial costs.

[0045] In some embodiments of the present application, Figure 3 As shown, the vibration assembly 1 includes an outer shell 3, a flexible shaft 2, a transmission shaft 12 and an eccentric block 11. The outer shell 3 is connected to the rake frame. A plurality of bearings 13 are installed on the transmission shaft 12. The transmission shaft 12 is fixed in the outer shell 3 through the bearings 13. The eccentric block 11 is fixedly installed on the transmission shaft 12. One end of the flexible shaft 2 is connected to the transmission shaft 12, and the other end of the flexible shaft 2 extends out of the outer shell 3 and is connected to the driving member 5. The driving member 5 drives the flexible shaft 2 to rotate, and the flexible shaft 2 drives the transmission shaft 12 to rotate, and the transmission shaft 12 drives the eccentric block 11 to rotate. Under the action of the eccentric block 11, the outer shell 3 vibrates, thereby driving the rake frame to vibrate. The vibration of the rake frame causes the high-concentration materials of the rake frame and its periphery to vibrate, and the vibration of the outer shell 3 can drive the materials around the outer shell 3 to vibrate accordingly, thereby intensifying the vibration discharge of the underflow materials. Under the action of the vibration force and gravity, the high-concentration materials at the bottom of the pool body 4 can be quickly discharged, preventing the thickener from being pressed due to the high concentration of the underflow materials and the accumulation of materials, so that the thickener can operate efficiently.

[0046] Exemplarily, the number of the bearings 13 is two, and the eccentric mass 11 is disposed between the two bearings 13. This arrangement makes the transmission shaft 12 more stable, and the position of the eccentric mass 11 is relatively stable.

[0047] Exemplarily, the two bearings 13 are respectively the first bearing 13 and the second bearing 13. The transmission shaft 12 is provided with a first limiting structure on the side of the first bearing 13 away from the second bearing 13. The first limiting structure cooperates with the first bearing 13 to block the transmission shaft 12 from moving in the direction close to the second bearing 13. The transmission shaft 12 is provided with a second limiting structure on the side of the second bearing 13 away from the first bearing 13. The second limiting structure cooperates with the second bearing 13 to block the transmission shaft 12 from moving in the direction close to the first bearing 13. This setting can limit the position of the transmission shaft 12, and further limit the position of the eccentric block 11, thereby preventing the eccentric block 11 from moving with the transmission shaft 12 and hitting the bearing 13, thereby causing damage to the bearing 13. In other words, the setting of the first limiting structure and the second limiting structure can protect the bearing 13 from damage.

[0048] Exemplarily, the first limiting structure and the second limiting structure are both pins 15, and the pins 15 are detachably mounted on the transmission shaft 12. The pins 15 are easy to disassemble and assemble, thereby facilitating the disassembly and assembly of the vibration mechanism.

[0049] In the embodiments of the present application, Figure 1 and Figure 2As shown, the rake frame includes a small rake 10, at least one long rake 8 and at least one short rake 9. The small rake 10 is arranged at the end of the main shaft 7 away from the pool mouth of the pool body 4. Each long rake 8 and each short rake 9 are arranged at the end of the main shaft 7 away from the pool mouth of the pool body 4, and are spaced along the circumference of the main shaft 7. The small rake 10, each long rake 8 and each short rake 9 are correspondingly provided with a vibration mechanism. In other words, the small rake 10 is correspondingly provided with a vibration mechanism, and the vibration component 1 (outer shell 3) of the vibration mechanism is connected to the small rake 10, each long rake 8 is correspondingly provided with a vibration mechanism, and the vibration component 1 (outer shell 3) of the vibration mechanism is connected to the corresponding long rake 8, and each short rake 9 is correspondingly provided with a vibration mechanism, and the vibration component 1 (outer shell 3) of the vibration mechanism is connected to the corresponding short rake 9. The vibration mechanism is arranged on the small rake 10, each long rake 8 and each short rake 9 to accelerate the discharge of high-concentration materials at the bottom of the pool body 4. In addition, the small rake 10, each long rake 8 and each short rake 9 are all provided with a vibration mechanism, which can also solve the situation that the thickener is about to press the rake or has already pressed the rake. When the rake is about to press the rake or has already pressed the rake, the thickener provided in the embodiment of the present application discharges the material around the rake frame (the small rake 10, each long rake 8 and each short rake 9) by vibration, and then gradually rotates the rake frame to gradually vibrate and discharge the material around the rake frame, thereby gradually discharging the pressed material. In other words, the thickener provided in the embodiment of the present application can solve the situation that the thickener is about to press the rake or has already pressed the rake, that is, it prevents the thickener from pressing the rake, and at the same time solves the problem after the thickener presses the rake.

[0050] It is worth noting that the embodiment of the present application can install a vibration mechanism on all rake frames in the small rake 10, each long rake 8 and each short rake 9, and can also install a vibration mechanism on some rake frames. No specific limitation is made here. Installing a vibration mechanism on all rake frames in the small rake 10, each long rake 8 and each short rake 9 can discharge the pressed material when the rake is about to be pressed or has been pressed. Installing a vibration mechanism on some rake frames can regularly turn on the vibration mechanism to prevent the occurrence of rake pressing accidents.

[0051] In some embodiments of the present application, the thickener further includes a mounting platform 6, which is fixed to an open end of the main shaft 7 close to the tank body 4, and the driving member 5 is mounted on the mounting platform 6. The mounting platform 6 is provided to provide a mounting position for the driving member 5, and the mounting platform 6 is fixed to the main shaft 7, so that the mounting platform 6 can rotate with the rotation of the main shaft 7, and then the vibration mechanism can rotate with the main shaft 7, thereby realizing the synchronous rotation of the main shaft 7, the vibration mechanism and the rake frame. In addition, the mounting platform 6 is fixed to an open end of the main shaft 7 close to the tank body 4, so that the mounting platform 6 can be located above the liquid level in the tank body 4, thereby enabling the driving member 5 to be located outside the liquid.

[0052] Exemplarily, the driving member 5 is a motor, and the rotation of the motor drives the flexible shaft 2 to rotate. Exemplarily, the flexible shaft 2 is a steel wire flexible shaft 2, and the steel wire flexible shaft 2 can transmit torsional force, so that the transmission shaft with an axial direction different from the axial direction of the motor output shaft rotates.

[0053] like Figure 4 As shown, the mounting platform 6 is provided with a through hole (not shown in the figure) near the main shaft 7. In the vibration mechanism corresponding to the long rake 8 and the vibration mechanism corresponding to the short rake 9, the output end of the motor faces the outside of the mounting platform 6, and in the vibration mechanism corresponding to the small rake 10, the motor (such as Figure 4 The output end of the small rake vibration motor 14) faces the through hole, and the part of the vibration component 1 connected to the motor passes through the through hole and is connected to the output end of the motor.

[0054] When the thickener provided in the embodiment of the present application is used:

[0055] When the concentration of the bottom material becomes high and the thickener rake frame has been lifted to the highest point and is about to be raked, the driving member 5 of the vibration mechanism is turned on. The driving member 5 drives the flexible shaft 2 and the transmission shaft 12 to rotate, so that the eccentric block 11 on the transmission shaft 12 generates centrifugal force, which is transmitted to the outer shell 3 through the bearing 13, so that the vibration component 1 generates circumferential vibration. Since the vibration component 1 is connected to the thickener rake frame, the thickener rake frame and the surrounding high-concentration bottom flow materials vibrate, thereby accelerating the discharge of the bottom material.

[0056] When the thickener rake has stopped running, that is, the rake has been pressed, first turn on the vibration mechanism to discharge the material around the rake, then turn on the drive mechanism of the thickener to drive the main shaft 7 to rotate. If the thickener rake rotates a certain angle and stops running again, this is because the material in the thickener has been compacted, and the vibration mechanism has only discharged the material around the thickener rake, while other places are still in a compacted state because they have been pressed. At this time, just turn on the vibration mechanism again at the position where the rake stops, and the compacted material at the new position of the rake can be discharged. Repeat the above steps several times until the rake rotates smoothly, indicating that the material around the rake and the underflow has been discharged. At this time, the operating pressure of the thickener rake will be greatly reduced, and the main shaft 7 transmission system of the thickener can be started, and the thickener can operate normally.
