A vertical centrifuge for solid-liquid separation

Abstract

The present invention relates to the technical field of centrifuges, and specifically to a vertical centrifuge for solid-liquid separation, which solves the problem that when extracting water after centrifugation, the deposited solid particles may be mixed with the water source again, and because the separated solid particles are small, it takes a long time to completely clean them, thereby increasing the interval time between two centrifugal treatments of the equipment. It includes a vertical centrifuge body. The present invention uses a particle isolation mechanism to cover the deposited solid particles with a fine-pore filter screen, and uses a centrifugal gap reduction mechanism to directly move the bottom of the centrifuge tank containing solid particles inside to the outside of the equipment, and install a new centrifuge tank bottom to work between them. The above technical solution can prevent the solid particles from mixing with the separation liquid again when the separation liquid is extracted, and at the same time, the time interval when the equipment performs centrifugal treatment is reduced by directly replacing the bottom of the centrifuge tank.

Description

Technical Field

[0001] The invention relates to the technical field of centrifuges, in particular to a vertical centrifuge used for solid-liquid separation. Background Art

[0002] Vertical centrifuge is a solid-liquid separation equipment widely used in industrial production. It has the advantages of good separation effect, strong processing capacity and easy operation. This equipment adopts high-speed rotation and uses centrifugal force to separate solid and liquid particles with different densities. When the liquid containing solid particles enters the centrifuge, through high-speed rotation, the solid particles with higher density will be deposited to the bottom of the centrifuge, while the liquid with lower density will be thrown to the outside of the centrifuge, thereby realizing the separation of solid and liquid. The whole system cleverly applies the dual effects of centrifugal force and gravity to realize the continuous operation of the equipment and achieve high working efficiency.

[0003] However, when the centrifugal treatment is completed and the liquid after solid separation is extracted, the solid particles located on the lower side of the centrifuge may be mixed with the liquid again due to the extraction force, thereby causing pollution to the liquid after centrifugation. After using the vertical centrifuge for solid-liquid separation, the solid particles will be uniformly collected on the lower side of the equipment. Since the solid particles are small and located on the lower side of the equipment, it is difficult to completely clean them, and it takes a long time to completely clean them, thereby increasing the interval time between two centrifugal treatments of the equipment and reducing the processing efficiency of the equipment. Therefore, it does not meet the existing needs. We propose a vertical centrifuge for solid-liquid separation. Summary of the invention

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figures 1 to 6 , an embodiment provided by the present invention: a vertical centrifuge for solid-liquid separation, comprising a vertical centrifuge body 1, the lower end surface of the vertical centrifuge body 1 is connected with a centrifugal gap reduction mechanism 2, the centrifugal gap reduction mechanism 2 comprises a slide rail 201, a centrifugal tank body 218, a lower gear ring 219, two centrifugal tank bottoms 203, two upper gear rings 204 and two movable connection mechanisms, the lower gear ring 219 is fixed to the outer side of the lower end surface of the centrifugal tank body 218, the two upper gear rings 204 are respectively fixed to the outer side of the upper end surfaces of the two centrifugal tank bottoms 203, and the top of the tooth head located on the lower gear ring 219 and the upper gear ring 204 is arc-shaped;

[0030] The lower end surface of the first centrifugal tank bottom 203 from left to right fits with the lower end surface of the centrifugal tank body 218, and the upper toothed ring 204 and the lower toothed ring 219 fixed on the outer surface of the first centrifugal tank bottom 203 from left to right are engaged with each other, and the centrifugal tank bottom 203 can be moved up and down on the outer surface of the slide rail 201 through a movable connection mechanism;

[0031] The bottom 203 of the first centrifuge tank from left to right contains solid particles 14, and a separation liquid 15 located inside the centrifuge tank body 218 is provided above the solid particles 14. A particle isolation mechanism installed on the upper end surface of the vertical centrifuge body 1 is provided above the separation liquid 15. The particle isolation mechanism includes a push plate 6, an adsorption fixing groove 7, a filter screen frame 8, an annular magnet 9, a fine-pore filter screen 16, an adsorption fixing mechanism and a lifting mechanism. The adsorption fixing groove 7 is located at the lower end surface of the push plate 6, the fine-pore filter screen 16 is fixed inside the filter screen frame 8, and the annular magnet 9 is fixed to the lower end surface of the filter screen frame 8. The filter screen frame 8 can be fixed inside the adsorption fixing groove 7 by the adsorption fixing mechanism, and the push plate 6 can be moved up and down by the lifting mechanism;

[0032] The outer side of the lower end surface of the filter screen frame 8 is an inclined surface, and the inner wall of the bottom 203 of the centrifugal tank is also an inclined surface.

[0033] A control panel 3 is fixedly installed on one side of the outer surface of the vertical centrifuge body 1, and the adsorption fixing mechanism, the lifting mechanism and the movable connection mechanism are all electrically connected to the control panel 3; the operation of the adsorption fixing mechanism, the lifting mechanism and the movable connection mechanism can be controlled through the control panel 3.

[0034] The lifting mechanism includes a centrifuge cover 4, a horizontal cylinder 5 is fixedly installed on the lower side of the inside of the centrifuge cover 4, and the piston rod of the horizontal cylinder 5 is fixed to the push plate 6; when the equipment needs to be used, check the use of each mechanism, move the device to the working area and connect the power supply, open the centrifuge cover 4, and add a water source containing solid particles inside the centrifuge tank body 218.

[0035] The adsorption fixing mechanism includes two fixed horizontal bar cylinders 10, and a piston plate 13 is connected to the piston rod of the fixed horizontal bar cylinder 10. The outer side of the piston plate 13 is provided with an adsorption fixing head 11 fixed to the inside of the push plate 6 and connected between the lower end surface and the upper end surface of the filter frame 8. A piston groove 12 is provided in the middle position of the lower end surface of the adsorption fixing head 11, and the piston plate 13 is located on the upper side of the piston groove 12. When the water source is added, pick up the filter frame 8 and insert it into the adsorption fixing groove 7 until its upper end surface is connected to the adsorption fixing head 1 1, when the two are connected, the piston plate 13 located inside the piston groove 12 is pulled upward by the fixed horizontal cylinder 10 to extract the air inside the piston groove 12 to fix the filter frame 8 inside the adsorption fixing groove 7. After the adsorption fixing groove 7 is fixed, the centrifuge cover 4 is closed again, and then the vertical centrifuge body 1 is started to perform solid-liquid separation on the water source. Under the action of high-speed centrifugal force, the solid particles 14 located in the water source will be deposited on the bottom 20 of the centrifuge tank connected to the centrifuge tank body 218. 3, and the water source without solid particles 14 inside will become separation liquid 15. When the solid-liquid separation process is completed, the push plate 6 and the filter frame 8 inside the adsorption fixing groove 7 fixed on the lower end surface of the push plate 6 are pushed downward by the horizontal cylinder 5. When the annular magnet 9 fixed on the lower end surface of the filter frame 8 contacts the inner wall of the bottom 203 of the centrifugal tank, the filter frame 8 can be fixed to the inside of the control panel 3 by the magnetic force of the annular magnet 9 itself. When the two are in contact, the piston plate 13 is moved downward by the fixed horizontal cylinder 10 to release the fixation of the filter frame 8. When the fixation of the filter frame 8 is released, the push plate 6 is recovered by the horizontal cylinder 5. The fine-pore filter 16 fixed on the filter frame 8 can cover the solid particles 14 located inside the bottom 203 of the centrifugal tank. The above technical solution can prevent the solid particles 14 from mixing with the separation liquid 15 again under the influence of the extraction force when the separated separation liquid 15 is extracted, thereby ensuring the purity of the separation liquid 15 itself after solid-liquid separation.

[0036] Since the outer side of the lower end surface of the filter screen frame 8 and the inner wall of the bottom 203 of the centrifugal tank are both inclined surfaces, when the filter screen frame 8 is moved downward, only the inclined surface located at the lower end surface of the filter screen frame 8 will contact the inner wall of the bottom 203 of the centrifugal tank, and after the two are in contact, the lower end surface of the filter screen frame 8 will maintain a distance from the inner wall of the bottom 203 of the centrifugal tank. The above technical solution can prevent the downwardly moving filter screen frame 8 from directly contacting the solid particles 14, thereby causing the solid particles 14 to float inside the separation liquid 15 under the influence of this impact force.

[0037] The movable connection mechanism includes an electric intelligent slide 202, a stepper motor 205 is fixedly installed on the lower side of the electric intelligent slide 202, the output shaft of the stepper motor 205 is connected to a transmission shaft 206 through a coupling, a medium-sized gear 207 is fixedly sleeved on the outer surface of the transmission shaft 206, and a small gear 208 is meshed on both sides of the outer surface of the medium-sized gear 207, and the axis of the small gear 208 is connected to a lifting threaded rod 209, and the outer surface of the lifting threaded rod 209 is sleeved with an internal threaded sleeve 210, and a lifting platform 221 is fixed between the two internal threaded sleeves 210, and the bottoms 203 of the two centrifugal tanks are respectively connected to the middle position of the upper end faces of the two lifting platforms 221 through roller bearings; when the separation liquid 15 is exhausted, the stepper motor 205 inside the first electric intelligent slide 202 from left to right is started, and the stepper motor 205 can drive the transmission shaft 206 connected thereto and the medium-sized gear 208 fixedly sleeved on the outer surface of the transmission shaft 206. 07 rotates, the rotating medium-sized gear 207 can drive the small gear 208 meshing therewith and the lifting threaded rod 209 connected to the axis of the small gear 208 to rotate. Since the internal threaded sleeve 210 sleeved on the outer surface of the lifting threaded rod 209 is fixed with the lifting platform 221, the internal threaded sleeve 210 cannot rotate by itself. When the lifting threaded rod 209 rotates, the internal threaded sleeve 210, which is threadedly connected to it but cannot rotate by itself, will move up and down on the outer surface of the lifting threaded rod 209. At this time, the internal threaded sleeve 210 moves downward. During the downward movement of the internal threaded sleeve 210, the lifting platform 221 fixed thereto and the centrifuge tank bottom 203 installed on the upper end surface of the lifting platform 221 through a roller bearing will move downward together. When the centrifuge tank bottom 203 containing solid particles 14 and a fine-pore filter 16 inside leaves the interior of the vertical centrifuge body 1 and is completely exposed to the outside world, the centrifuge tank bottom 203 is moved forward by the electric intelligent slide 202;

[0038] Then, another electric intelligent slide 202 is started, and the electric intelligent slide 202 is moved to the corresponding connection position. Then, the corresponding centrifuge tank bottom 203 is moved upward by the stepper motor 205 installed inside the electric intelligent slide 202. As the centrifuge tank bottom 203 rises, the upper gear ring 204 fixed on the upper end surface of the centrifuge tank bottom 203 will contact the lower gear ring 219 fixed on the lower end surface of the centrifuge tank body 218. As the centrifuge tank bottom 203 rises, the upper gear ring 204 will mesh with the lower gear ring 219. When the two are fully meshed, when the centrifuge tank body 218 is driven to rotate by the vertical centrifuge body 1, the upper gear ring 204 will be used to move the centrifuge tank body 218 upward. The bottom 203 of the centrifugal tank driven by the lower gear ring 219 will rotate synchronously therewith. When the bottom 203 of the centrifugal tank is installed, the centrifuge cover 4 is opened again to add the water source containing solid particles inside and a new filter frame 8 is installed inside the adsorption fixed tank 7. When all preparations are completed, the second solid-liquid separation process is carried out. When the equipment is carrying out the second solid-liquid separation process, the staff can take advantage of this gap to clean the bottom 203 of the centrifugal tank containing solid particles 14 and the fine-pore filter screen 16. The above technical solution can shorten the gap between the two centrifugal processes of the equipment. At the same time, since the cleaning work is mainly carried out outside the equipment, the convenience of cleaning is also improved.

[0039] Since the ends of the teeth on the upper tooth ring 204 and the lower tooth ring 219 are both arc-shaped, when the ends of the teeth on the upper tooth ring 204 and the lower tooth ring 219 collide, the upper tooth ring 204 or the lower tooth ring 219 can be slightly rotated through its arc surface to ensure that the two can bite each other. The above technical solution can prevent the ends of the teeth on the upper tooth ring 204 and the lower tooth ring 219 from colliding, which would cause the two to be unable to bite each other.

[0040] A transmission shaft 212 located inside the lifting platform 221 is provided above the transmission shaft 206, and a square slot 213 extending to the inside of the transmission shaft 212 is provided in the middle position of the lower end surface of the transmission shaft 212, and a square transmission rod 211 inserted into the square slot 213 is connected to the upper end surface of the transmission shaft 206; the cross-sectional shape of the square transmission rod 211 is square, the outer surface of the square transmission rod 211 fits with the inner wall of the square slot 213, and the square transmission rod 211 is slidingly connected to the square slot 213; during the rotation of the transmission shaft 206, the square transmission rod 211 fixed thereto will rotate therewith, because the outer surface of the square transmission rod 211 fits with the inner wall of the square slot 213 located on the lower end surface of the transmission shaft 212, so when the square transmission rod 211 rotates, the transmission shaft 212 will rotate synchronously.

[0041] A synchronous rotating shaft 215 is provided on both sides of the top end of the transmission shaft 212. The two synchronous rotating shafts 215 are connected in series with the transmission shaft 212 through a synchronous chain 216 respectively, and the upper end surface of the synchronous rotating shaft 215 is connected to a fixed thread head 214 located on the outer side of the upper end surface of the electric intelligent slide 202; when the transmission shaft 212 rotates, the synchronous rotating shaft 215 connected in series with it through the synchronous chain 216 and the fixed thread head 214 connected to the upper end surface of the synchronous rotating shaft 215 will rotate together.

[0042] A circular connecting groove 220 located on the lower end surface of the vertical centrifuge body 1 is provided on the outer side of the top end of the first electric intelligent slide 202 from left to right, and a fixed threaded opening 217 is provided on both sides of the inner wall of the upper end of the circular connecting groove 220. The fixed threaded head 214 located on the outer side of the upper end surface of the first electric intelligent slide 202 from left to right is located inside the fixed threaded opening 217, and the external thread of the fixed threaded head 214 matches the internal thread of the fixed threaded opening 217; when the bottom 203 of the centrifuge tank is moved upward by the electric intelligent slide 202, the fixed threaded head 214 located on the outer side thereof will move together, and when the bottom 203 of the centrifuge tank contacts In front of the centrifugal tank body 218, the fixed thread head 214 that rotates and moves upward will contact the fixed thread opening 217, and through the transmission of its thread structure, the fixed thread head 214 will gradually enter the interior of the fixed thread opening 217, and through the threaded connection structure here, it can be fixed to the electric intelligent slide 202 and the centrifugal tank bottom 203 installed on the upper end surface of the electric intelligent slide 202 through the roller bearing. The above technical solution can prevent the centrifugal tank bottom 203 from moving downward without authorization, thereby causing a gap between the centrifugal tank bottom 203 and the small gear 208, and the separation liquid 15 leaks from this gap;

[0043] When the electric intelligent slide 202 is moved downward, the fixed thread head 214 will rotate in the opposite direction. Through the thread transmission of the fixed thread head 214 rotating in the opposite direction, the fixed thread head 214 will gradually leave from the inside of the fixed thread opening 217 .

[0044] A metal cover is provided in front of the stepper motor 205 and is located on the outer surface of the electric intelligent slide 202, and the electric intelligent slide 202 and the metal cover are fixed by screws; the metal cover can protect the internal structure of the electric intelligent slide 202, and when the internal structure of the electric intelligent slide 202 fails, the metal cover can be removed to repair its internal structure.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
