Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1-8 As shown, this utility model provides a solid-liquid centrifuge for chemical engineering, including a casing 100 and a motor 200 installed inside the casing 100. The casing 100 has a partition structure 300 that divides the internal space of the casing 100 into several equal centrifuge chambers 400. Several liquid outlets 101 corresponding to the centrifuge chambers 400 are connected to the outer wall of the casing 100. An openable cover 102 is installed on the top of the casing 100. Several feeding ports 103 corresponding to the centrifuge chambers 400 are connected to the cover 102. A mounting platform 500 is rotatably installed in each centrifuge chamber 400. A centrifuge separation cylinder 600 is detachably installed on the mounting platform 500. The aperture of each centrifuge separation cylinder 600 is different. A transmission mechanism 700 is provided between the motor 200 and the mounting platform 500. The motor 200 drives the mounting platform 500 through the transmission mechanism 700 to rotate the centrifuge separation cylinder 600 to achieve centrifugal separation operation.

[0030] In this embodiment, the partition structure 300 includes a partition 301, a dividing plate 302, and a receiving cylinder 303. The partition 301 is fixedly connected to the inside of the chassis 100, and the receiving cylinder 303 is fixedly connected above the partition 301. The dividing plate 302 is distributed in a circular array along the circumference of the receiving cylinder 303 and is fixedly connected to the partition 301, the chassis 100, and the receiving cylinder 303 respectively.

[0031] In this embodiment, each mounting platform 500 includes a rotating shaft 501 rotatably mounted on the bottom wall of the casing 100. The top end of the rotating shaft 501 passes through the partition 301 and extends into the centrifuge chamber 400. The rotating shaft 501 and the partition 301 are connected by a sealed bearing. The lower end of the rotating shaft 501 is fixedly sleeved with a support platform 502, and the upper end of the rotating shaft 501 is fixedly sleeved with a mounting plate 503.

[0032] In this embodiment, the transmission mechanism 700 includes a main transmission wheel 701 and a secondary transmission wheel 702. The motor 200 is fixedly mounted on the partition 301 and located inside the receiving cylinder 303. The output shaft of the motor 200 passes through the partition 301 and is connected to the main transmission wheel 701. The secondary transmission wheel 702 is fixedly sleeved on the rotating shaft 501. A belt 703 is provided between the main transmission wheel 701 and the secondary transmission wheel 702. A tensioning component 704 for adjusting the tension of the belt 703 is installed on the bottom wall of the housing 100. The motor 200 drives the main transmission wheel 701 to rotate and the belt 703 to rotate the secondary transmission wheel 702, thereby driving the rotating shaft 501 to rotate the centrifugal separation cylinder 600.

[0033] In this embodiment, the tensioning assembly 704 includes a support plate 7041 fixedly connected to the bottom wall of the inner wall of the housing 100. An electric actuator 7042 is mounted on the support plate 7041. A movable plate 7043 is mounted on the output end of the electric actuator 7042. Two tensioning wheels 7044 are rotatably arranged on the movable plate 7043. The belt 703 passes through the gap between the two tensioning wheels 7044 and contacts the two tensioning wheels 7044 respectively. In actual use, the movable plate 7043 can be pushed by the electric actuator 7042 corresponding to the selected centrifugal separator 600, and the belt 703 is tensioned by the two tensioning wheels 7044 to realize the rotation of the centrifugal separator 600. At this time, the belts 703 corresponding to other centrifugal separators 600 can remain untensioned, and other centrifugal separators 600 will not rotate, avoiding the idle running of unused centrifugal separators 600 and reducing the transmission efficiency of the motor 200.

[0034] In this embodiment, an annular groove 504 is provided on the support platform 502, and a sealing ring 505 is provided in the annular groove 504. The end of the centrifugal separator 600 can be inserted into the annular groove 504 and abut against the sealing ring 505. When installing the centrifugal separator 600, the end of the centrifugal separator 600 can be inserted into the annular groove 504 for positioning, and then the sealing ring 505 seals the support platform 502 and the centrifugal separator 600 to prevent leakage without centrifugation.

[0035] In this embodiment, slots 506 are provided on both sides of the top of the mounting plate 503. A locking block 601 that engages with the slots 506 is fixedly connected to the inner wall of the centrifugal separator 600. An insertion hole 602 is provided on the side of the locking block 601. A receiving groove 507 matching the insertion hole 602 is provided in the mounting plate 503. An insertion rod 508 is provided in the receiving groove 507. When the centrifugal separator 600 needs to be installed, the locking block 601 of the centrifugal separator 600 is aligned with the slots 506 of the mounting plate 503 and inserted to achieve the initial positioning and fixation of the centrifugal separator 600 and the mounting plate 503.

[0036] In this embodiment, one end of the insertion rod 508 passes through the mounting plate 503 and is inserted into the insertion hole 602. A slidable paddle 509 is fixedly connected to the insertion rod 508 and is disposed in the receiving cavity. A spring 510 is installed between one side of the paddle 509 and the inner wall of the receiving cavity. Before the locking block 601 and the locking slot 506 are engaged, the paddle 509 is moved to compress the spring 510 and move the insertion rod 508. After the locking block 601 and the locking slot 506 are engaged, the paddle 509 is released. At this time, the spring 510 restores its elasticity and firmly fixes the insertion rod 508 in the insertion hole 602, thereby realizing the installation of the centrifugal separator 600 and the mounting plate 503. Conversely, disassembly only requires adjusting the paddle 509. The disassembly and assembly are convenient and facilitate the maintenance or replacement of the centrifugal separator 600.

[0037] How to use and how to work this device:

[0038] When using this device, first, move the lever 509 to compress the spring 510, align the locking block 601 of the centrifugal separator 600 to be installed with the locking slot 506 on the mounting plate 503 and insert it. The locking block 601 and the locking slot 506 initially engage, and the bottom end of the centrifugal separator 600 is inserted into the annular groove 504. Release the lever 509, the spring 510 returns to its elasticity, and pushes the insertion rod 508 through the mounting plate 503 and into the insertion hole 602 of the locking block 601, thus firmly fixing the centrifugal separator 600 on the mounting plate 503, thereby achieving the installation of the centrifugal separator 600. To disassemble, simply move the lever 509 again to compress the spring 510, and the insertion rod 508 will come out of the insertion hole 602, allowing the centrifugal separator 600 to be removed from the mounting plate 503 for easy maintenance or replacement.

[0039] After the centrifuge cylinder 600 is installed, select a centrifuge cylinder 600 with an appropriate aperture size according to the solid-liquid mixture to be separated. After feeding the mixture into the cylinder through the feed port 103, use the tensioning component 704 to adjust the tension of the belt 703 to ensure that the belt 703 corresponding to the selected centrifuge cylinder 600 is in a taut state, while the belts 703 corresponding to other centrifuge cylinders 600 remain untaut to avoid unnecessary idling. Then start the motor 200. The motor 200 drives the rotating shaft 501 to rotate through the main drive wheel 701, the belt 703 and the auxiliary drive wheel 702, which in turn drives the centrifuge cylinder 600 to rotate. The solid particles are thrown towards the cylinder wall under the action of centrifugal force, while the liquid phase flows out through the holes on the cylinder wall, thus realizing solid-liquid separation.

[0040] In summary, the partition structure 300 rationally divides the space of the chassis 100 into multiple centrifuge chambers 400. The centrifuge separation cylinders 600 in each centrifuge chamber 400 can be quickly disassembled, and chemical raw materials of different particle sizes can be separated within the chassis 100. Each centrifuge separation cylinder 600 works independently without interfering with each other, enhancing the parallel processing capability of the equipment, enabling multiple separation tasks to be performed simultaneously, and improving the overall work efficiency.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
