Description

Technical Field

[0001] This utility model relates to the field of m-p-cresol separation technology, specifically to a m-p-cresol centrifugal separation device with high-efficiency separation function. Background Technology

[0002] p-cresol can be used to produce plasticizers, disinfectants, insulating varnishes, organometallic flotation agents, plastics, pesticides, etc. It can also be used as a colorant for color film. In a reactor, a mixture of cresol and benzylamine is added and stirred until homogeneous. The mixture is then gradually cooled to -0.8℃, allowing p-cresol to crystallize. The crystals are then separated from the mother liquor using a centrifuge. The crystals and benzylamine are then dissolved and extracted to obtain pure p-cresol, while the benzylamine is recovered. After separation, the p-cresol content in the mother liquor increases. Extraction is then performed to separate it from the benzylamine. The mother liquor containing a large amount of p-cresol and a small amount of m-cresol is then introduced into a cooling tank for crystallization. The resulting p-cresol crystals and the mother liquor containing m-cresol are separated by a centrifuge to obtain pure p-cresol monomer and the remaining mother liquor (for recycling).

[0003] When using a centrifuge to separate cresol crystals from the mother liquor, common centrifuges are usually enclosed, making it impossible to feed materials while the centrifuge is running. When separating piles of materials, the close contact between the materials requires a long centrifugation process, which significantly affects the efficiency of the centrifugation separation.

[0004] Therefore, we propose a centrifugal separation device for m-p-cresol with high efficiency separation function. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal separation device for m-p-cresol with high efficiency separation function, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal separation device for m-p-cresol with high-efficiency separation function, comprising an outer shell, a top cover installed on the upper surface of the outer shell, a centrifugal tank installed inside the outer shell, a centrifugal assembly installed inside the outer shell, the centrifugal assembly being used for centrifugal separation of cresol crystals and mother liquor, and a feeding assembly installed above the outer shell, the feeding assembly being used to control the cresol crystals of the mixed mother liquor to enter the interior of the centrifugal tank, the feeding assembly being able to continue feeding the centrifugal tank while it is in operation.

[0007] Preferably, the centrifuge assembly includes an inclined plate, which is fixedly connected to the lower middle part of the inner wall of the outer shell. A fixing frame is fixedly installed on the lower part of the inner wall of the outer shell. A drive motor is fixedly connected to the bottom surface of the fixing frame. The output shaft of the drive motor passes through the upper surface of the inclined plate and is rotatably connected to the inclined plate. A hexagonal prism is fixedly connected to the output shaft of the drive motor. The bottom surface of the centrifuge tank is inserted into the hexagonal prism.

[0008] Preferably, the bottom wall of the centrifuge tank is provided with a frustum block.

[0009] Preferably, the feeding assembly includes a top cover, which is installed on the upper surface of the outer casing. A feed pipe is fixedly connected to the upper surface of the top cover, and the feed pipe extends into the interior of the centrifuge tank. A feed inlet is fixedly connected to the top end of the feed pipe.

[0010] Preferably, a ring of levers is fixedly installed below the outer surface of the feed tube, and the levers are made of rubber.

[0011] Preferably, a cylindrical rod is placed inside the feed pipe, a block is fixedly connected to the bottom surface of the cylindrical rod, a crossbar is fixedly connected to the upper surface of the cylindrical rod, and two symmetrical elastic steel plates are fixedly connected between the bottom surface of the crossbar and the upper surface of the top cover.

[0012] Preferably, the block has a smooth outer surface.

[0013] Preferably, the feed tube can be pulled out from the top opening of the centrifuge tank along with the lever.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When the device is in operation, first turn on the power switch connected to the drive motor. The output shaft of the drive motor will rotate, which will drive the hexagonal prism to rotate simultaneously. The centrifuge tank is connected to the hexagonal prism, and the rotation of the drive motor will drive the centrifuge tank to rotate synchronously. At this time, the material inside the centrifuge tank can be centrifuged and separated. The mother liquor ejected from the centrifuge tank will flow to the side of the inclined plate with a lower horizontal height. At this time, the opening on the outer shell can be opened to collect the mother liquor. The set lever can be used to separate the material if it clumps together when the centrifuge tank is rotating, thereby improving the overall centrifugation efficiency of the device.

[0016] By incorporating centrifugal components, the entire device can achieve centrifugal separation, further facilitating the collection of the mother liquor after centrifugation.

[0017] 2. When the centrifuge tank is rotating to separate materials, a small portion of the material can be added to the centrifuge tank initially, and then the material can be continuously added while the centrifuge tank is operating. Specifically, the mixture of cresol crystals and mother liquor is first added to the inlet. The material will then enter the feed pipe. Pressing down on the crossbar will cause the cylindrical rod to lower the block. The material inside the feed pipe will then enter the centrifuge tank from the bottom. The frustum block helps to disperse the material as it enters the centrifuge tank. After a portion of the material has entered, releasing the pressure on the crossbar will allow the elastic steel plate to automatically reset the crossbar, thereby automatically resetting the block and sealing the feed pipe.

[0018] By setting up a feeding component, the entire device can be fed during operation, which can effectively avoid the accumulation of material caused by adding too much material at once, thus preventing incomplete centrifugal separation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] Example 1: A centrifugal separator for m-cresol with high efficiency separation function includes an outer shell 3, a top cover 17 installed on the upper surface of the outer shell 3, a centrifugal tank 6 installed inside the outer shell 3, a centrifugal assembly 1 installed inside the outer shell 3, the centrifugal assembly 1 being used for centrifugal separation of cresol crystals and mother liquor, and a feeding assembly 2 installed above the outer shell 3, the feeding assembly 2 being used to control the cresol crystals of the mixed mother liquor to enter the interior of the centrifugal tank 6, the feeding assembly 2 being able to ensure that the centrifugal tank 6 can still be fed while it is in operation.

[0027] The centrifuge assembly 1 includes an inclined plate 4, which is fixedly connected to the lower middle part of the inner wall of the outer shell 3. A fixing frame 9 is fixedly installed on the lower part of the inner wall of the outer shell 3. A drive motor 8 is fixedly connected to the bottom surface of the fixing frame 9. The output shaft of the drive motor 8 passes through the upper surface of the inclined plate 4 and is rotatably connected to the inclined plate 4. A hexagonal prism 7 is fixedly connected to the output shaft of the drive motor 8. The bottom surface of the centrifuge tank 6 is inserted into the hexagonal prism 7.

[0028] The bottom wall of the centrifuge tank 6 is provided with a frustum block 5.

[0029] When the device is in operation, first turn on the power switch that is electrically connected to the drive motor 8. At this time, the output shaft of the drive motor 8 will rotate, which will drive the hexagonal prism 7 to rotate simultaneously. The centrifuge tank 6 is connected to the hexagonal prism 7. At this time, the rotation of the drive motor 8 will drive the centrifuge tank 6 to rotate synchronously. At this time, the material inside the centrifuge tank 6 can be centrifuged and separated. The mother liquor thrown out by the centrifuge tank 6 will flow to the side of the inclined plate 4 with a lower horizontal height. At this time, the opening on the outer shell 3 can be opened to collect the mother liquor. The lever 11 can be used to separate the material if it clumps together when the centrifuge tank 6 is rotating, thereby improving the overall centrifugation efficiency of the device.

[0030] By incorporating centrifugal component 1, the entire device can achieve centrifugal separation, further facilitating the collection of the mother liquor after centrifugation.

[0031] Example 2: The feeding assembly 2 includes a top cover 17, which is installed on the upper surface of the outer shell 3. The upper surface of the top cover 17 is fixedly connected to a feed pipe 16, which extends into the interior of the centrifuge tank 6. The top end of the feed pipe 16 is fixedly connected to a feed inlet 10.

[0032] A ring of levers 11 is fixedly installed on the lower part of the outer surface of the feed pipe 16. The levers 11 are made of rubber.

[0033] A cylindrical rod 14 is placed inside the feed pipe 16. A block 15 is fixedly connected to the bottom surface of the cylindrical rod 14. A crossbar 12 is fixedly connected to the upper surface of the cylindrical rod 14. Two symmetrical elastic steel plates 13 are fixedly connected between the bottom surface of the crossbar 12 and the upper surface of the top cover 17.

[0034] The block 15 has a smooth outer surface.

[0035] The feed pipe 16, along with the lever 11, can be pulled out from the top opening of the centrifuge tank 6.

[0036] When the centrifuge tank 6 rotates to centrifuge and separate materials, a small portion of the material can be added to the centrifuge tank 6 first, and then the material can be continuously added while the centrifuge tank 6 is working. Specifically, the mixture of cresol crystals and mother liquor is first added to the inlet 10, and the material will enter the feed pipe 16. At this time, pressing down the crossbar 12 will cause the cylindrical rod 14 to drive the block 15 to descend. The material inside the feed pipe 16 will enter the centrifuge tank 6 from the bottom end of the feed pipe 16. The frustum block 5 can make the material more dispersed when it enters the centrifuge tank 6. After a portion of the material has entered, the pressure on the crossbar 12 is released. The elasticity of the elastic steel plate 13 will cause the crossbar 12 to automatically reset, thereby causing the block 15 to automatically reset and achieve the function of sealing the feed pipe 16.

[0037] By setting up the feeding component 2, the entire device can be fed during operation, which can effectively avoid the accumulation of material caused by adding too much material at once, resulting in incomplete centrifugal separation.
