Description

Technical Field

[0001] The present invention relates to the technical field of centrifuges, and more particularly to a solid-liquid separation centrifuge. Background Art

[0002] A solid-liquid separation centrifuge is a device that uses centrifugal force to separate solid and liquid substances. This device is widely used in multiple fields such as pharmaceuticals, environmental protection, chemical industry, food, and mining. It can be used for small-scale experiments in laboratories as well as large-scale processing in industrial production. Its working principle is based on the different centrifugal forces exerted by substances of different densities when rotating at high speed. When a mixture is fed into the rotating drum, due to the action of centrifugal force, the solid particles with a larger density will be thrown to the outside, while the liquid with a smaller density will remain inside or be thrown out of the drum, thus achieving the separation of the solid-liquid two phases.

[0003] With the continuous development and improvement of the design and technology of solid-liquid separation centrifuges, modern solid-liquid separation centrifuges not only pursue higher separation efficiency and processing capacity, but also strive to reduce energy consumption, reduce operating costs, and improve the automation level.

[0032] The pretreatment mechanism is used to pretreatment the material and convey the treated material into the drum 2. The pretreatment mechanism includes an installation box 3. A discharge trough 4 is arranged above the installation box 3. The discharge trough 4 is used to place the material to be pretreated. A conveying pipe 5 and a feeding pipe 6 are arranged below the discharge trough 4 on the installation box 3. One end of the feeding pipe 6 is connected to the conveying pipe 5, and the other end of the feeding pipe 6 is connected to the feeding port of the drum 2. A discharge mechanism 7 is arranged in the conveying pipe 5. The discharge mechanism 7 divides the conveying pipe 5 into two mutually separated pretreatment areas 501 and feeding areas 502. The discharge mechanism 7 is used to block solid materials or allow solid materials to enter the feeding area 502 from the pretreatment area 501. The feeding area 502 is located at Between the pretreatment area 501 and the feed pipe 6, the pretreatment area 501 of the feed pipe 6 is connected with the discharge trough 4, and the feed pipe 6 is located in the pretreatment area 501 and is provided with a crushing component 8 matching it. The crushing component 8 is used to squeeze and crush the material entering the discharge trough 4 into the pretreatment area 501 of the feed pipe 6 and leave the solid in the material in the pretreatment area 501 and the liquid enters the feed area 502. The end of the feed pipe 6 away from the drum 2 is provided with a pushing component 9 matching it.

[0033] In this embodiment, the discharge mechanism 7 includes a fixed plate 701 and a movable plate 702. The movable plate 702 is rotatably mounted on the fixed plate 701. The fixed plate 701 is fixedly mounted in the feed pipe 5 to divide the feed pipe 5 into two mutually separated pretreatment areas 501 and a feed area 502. Two first through holes 7011 are provided on the fixed plate 701, and two second through holes 7021 are provided on the movable plate 702. A second driving mechanism 11 is provided on the fixed plate 701. The second driving mechanism 11 is used to drive the first through holes 7011 and the second through holes 7021 to correspond to or stagger, so as to connect or block the pretreatment area 501 and the feed area 502. Of course, in addition to the structure in this embodiment, the discharge mechanism 7 can also be replaced by a valve.

[0034] The second driving mechanism 11 includes a second motor 1101 and a groove wheel 1102. The second motor 1101 is fixed on the fixed plate 701. The groove wheel 1102 is fixedly connected to the movable plate 702. The fixed plate 701 is located between the movable plate 702 and the groove wheel 1102. A first connecting rod 1103 is arranged on the output end of the second motor 1101. A shifting rod 1104 is eccentrically arranged on the first connecting rod 1103. Four notches 1105 matching the shifting rod 1104 are arranged on the groove wheel 1102 along the circumferential direction. The second motor 1101 is used to drive the first connecting rod 1103 to rotate and make the shifting rod 1104 disengage from the upper notch 1105 of the groove wheel 1102 and enter the next notch 1105, so as to drive the groove wheel 1102 to rotate intermittently.

[0035] The crushing member 8 has a crushing cutter head 801 and a crushing body 802 connected in sequence. The crushing cutter head 801 is used to crush the material. The crushing body 802 matches the feed pipe 6. The crushing body 802 is slidably arranged in the feed pipe 6. The crushing cutter head 801 is located between the crushing body 802 and the discharge mechanism 7.

[0036] The first driving mechanism 10 includes a third motor 1001, a first flywheel 1002, a second flywheel 1003, a second connecting rod 1004 and a third connecting rod 1005. The first flywheel 1002 and the second flywheel 1003 are coaxially rotatably installed on the installation box 3. One end of the second connecting rod 1004 is hinged on the first flywheel 1002, and the other end of the second connecting rod 1004 is hinged on the crushing member 8. One end of the third connecting rod 1005 is hinged on the second flywheel 1003, and the other end of the third connecting rod 1005 is hinged on the pushing member 9. The third motor 1001 is transmission-connected to the first flywheel 1002 and the second flywheel 1003, and the third motor 1001 is transmission-connected to the first flywheel 1002 and the second flywheel 1003 through a pulley mechanism.

[0037] The bottom of the feeding tank 4 and the feeding pipe 5 are interconnected through a connecting pipe. A discharge port 12 is provided at the bottom of the feeding tank 4. The discharge port is communicated with one end of the connecting pipe. The feeding tank 4 is formed by a plurality of feeding plates surrounding the discharge port 12 and connected end to end in sequence. The feeding plates are arranged to gradually incline downward from the outside of the feeding tank 4 towards the discharge port 12. An electric heating wire is installed below the feeding tank 4.

[0038] When the above solid-liquid separation centrifuge is in use, after the centrifuge starts working, cover the top cover, put the material into the feeding tank 4 through the feeding machine, start the electric heating wire, and make the material get preheated treatment on the feeding plate, so as to reduce the viscosity of the material and improve the separation conditions.

[0039] The material slides into the feeding port along the inclined surface of the feeding plate and enters the pretreatment area 501 of the feeding pipe 5 through the connecting pipe. After feeding for a time t and then stopping feeding, the solids in the material are blocked in the pretreatment area 501 by the discharging mechanism 7, and the liquid preferentially enters the feeding area 502. At this time, the third motor 1001 drives and controls the first flywheel 1002 and the second flywheel 1003 to rotate synchronously. At the same time, the second connecting rod 1004 and the third connecting rod respectively drive the corresponding crushing parts 8 and the pushing parts to reciprocate through the rotation of the first flywheel 1002 and the second flywheel 1003, so as to extrude and crush the material in the pretreatment area 501 of the feeding pipe, which is convenient for subsequent separation and prevents the solid matters in the material from being too large, so as to prevent grinding the internal structure during subsequent transportation in the drum 2.

[0040] After crushing for a time t, control the second motor 1101 of the discharging mechanism 7, and drive the first connecting rod 1103 to rotate. The first connecting rod 1103 drives the eccentrically arranged lever 1104 to rotate. The lever 1104 disengages from the previous notch 1105 of the grooved wheel 1102 and enters the next notch 1105, realizing the intermittent rotation of the grooved wheel 1102 until the first through hole 7011 on the fixed plate 701 corresponds to the second through hole 7021 on the movable plate 702, realizing the communication between the pretreatment area 501 and the feeding area 502 in the feeding pipe 5, so that the solid material enters the feeding area 502 through the pretreatment area 501 and is pushed by the reciprocating pushing part to the spiral conveyor in the drum 2 through the feeding pipe 6. When the drum 2 rotates at a high speed, different components in the material are separated due to density differences under the action of a strong centrifugal force. The solid particles are affected by a greater centrifugal force and quickly move towards the wall of the drum 2 and are discharged into the collection box through the solid outlet 201, while the liquid forms an inner layer. The spiral conveyor continues to convey the liquid, and the liquid passes through the filter screen to further separate from impurities, and the clarified liquid is conveyed to the liquid outlet 202 and discharged into the liquid storage barrel.

[0041] Set the input amount after the input of the single - time material feeding time t as G. After detecting the overall density of the solid - liquid mixture in the material through a densitometer, input the densities of pure solid and pure liquid into the data processor of the remote control terminal, thereby inversely calculating the solid - liquid ratio, and obtaining the weights of solid and liquid as Gs and Gl respectively. During the actual separation process, the discharged amounts of solid and liquid under normal loss are gsmin and glmin respectively, where gsmin < Gs and glmin < Gl. After the material is separated by the centrifuge, the solid and liquid enter the collection box and the liquid storage barrel respectively. Inside the collection box, the actual weight of the separated solid gs is fed back by the first weighing sensor, and the actual weight of the separated liquid gl is fed back by the second weighing sensor.

[0042] When gs is within the interval of [gsmin, Gs] and gl is within the interval of [glmin, Gl], it is a normal separation situation. When only gs < gsmin, it indicates that the separated solid amount is much less than its input amount. For this situation, it can be judged that the solid material is not sufficiently pulverized during the pulverization process. Therefore, it is caused by the insufficient pretreatment of the material in the discharge chute 4 not entering the pretreatment area 501 of the conveying pipe 5. The crushing part 8 performs a crushing operation on the material in the pretreatment area 501 of the conveying pipe 5, and the feeding mechanism 7 is started after time t / 2, so that this part of the pretreated material enters the drum 2 for separation. Finally, if the discharged amount gs increases and reaches gsmin, it indicates that the material separation is completed.

[0043] When gs < gsmin and at the same time gl < glmin, it indicates that the separated solid and liquid amounts are much less than their input amounts. For this situation, it can be judged that during the separation process, part of the solid blocks the filter screen when separating in the drum 2, resulting in the liquid being unable to be discharged from the liquid outlet 202 and part of the solid also unable to be discharged from the solid outlet 201. At this time, the surface of the filter screen needs to be brushed to remove the solid blocking the surface of the filter screen, so that it can be discharged together with the liquid from the liquid outlet 202 and collected through the liquid storage barrel. Finally, if the discharged amounts gs and gl both reach gsmin and glmin, it indicates that the material separation is completed.

[0044] Through the above - mentioned embodiments, by means of the feedback of measuring instruments and the data processing of the remote control console, the intelligent operation of the equipment is further realized, enabling the equipment to automatically judge whether the separation effect meets the standard, automatically intervene and solve problems when problems are found, greatly improving the production efficiency, reducing material loss and equipment maintenance costs, ensuring the integrity and high efficiency of the separation process, and at the same time improving the separation accuracy and output.

[0045] Based on the inspiration of the ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
