Description

Technical Field

[0001] This utility model relates to the field of chemical engineering technology, and more specifically, to an organic peroxide reaction liquid separation device. Background Technology

[0002] Organic peroxide reaction solution refers to a liquid reaction system containing organic peroxides. In the production of organic peroxides, solid additives or auxiliaries are usually used, requiring separation of the reaction solution from the solids. Existing separation devices typically use filters to block solid residues in the organic peroxide reaction solution. However, in actual use, when a certain amount of solid residue accumulates on the filter screen, it will clog the screen, reducing the throughput of the organic peroxide reaction solution. Therefore, the filter screen needs to be replaced regularly, resulting in high operating costs and complex operation. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides an organic peroxide reaction liquid separation device, which has the advantages of low cost and simple operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an organic peroxide reaction liquid separation device, comprising a separation cylinder, a filter screen rotatably connected to the middle of the separation cylinder, an adjusting gear fixedly installed at the front end of the filter screen, a feed pipe fixedly installed at the right end of the separation cylinder, a rotating tube provided at the top end of the separation cylinder, a distribution pipe fixedly installed at the bottom end of the rotating tube, a cylinder fixedly installed at the front side of the separation cylinder, a rack fixedly installed at the output end of the cylinder, and a discharge pipe fixedly installed at the bottom end of the separation cylinder.

[0005] As a preferred embodiment of this utility model, the separating cylinder includes a rotating section and a straight section. The rotating section is installed in the middle of the straight section, the filter screen is rotatably connected inside the rotating section, and the cylinder is fixedly installed on the outside of the rotating section.

[0006] As a preferred embodiment of this utility model, the bottom end of the distribution pipe is located in the inner cavity of the straight section, and a nozzle is fixedly installed at the bottom end of the distribution pipe.

[0007] In a preferred embodiment of this invention, the bottom end of the rack meshes with the top end of the adjusting gear, and both the rack and the adjusting gear are located on the outer side of the rotating section.

[0008] As a preferred embodiment of this utility model, a motor is fixedly installed at the top of the straight section, a drive gear is fixedly sleeved at the output end of the motor, and a gear ring is fixedly installed on the surface of the rotating tube.

[0009] As a preferred embodiment of this utility model, a positioning groove is provided at the top end of the inner cavity of the rotating tube, a limiting ring is rotatably connected to the inner cavity of the positioning groove, and a gas connecting pipe is fixedly installed in the inner cavity of the limiting ring.

[0010] In a preferred embodiment of this invention, the gear ring meshes with the drive gear, the drive gear is located on the right side of the gear ring, and the bend at the top of the gas connecting pipe is directed to the left.

[0011] As a preferred embodiment of this utility model, the rotating tube is rotatably connected to the top end of the straight section, and two positioning rings are fixedly installed on the surface of the rotating tube, with the two positioning rings located on the upper and lower sides of the top end of the straight section, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model sets the middle section of the separation cylinder as a rotating section, and sets a rotatable filter screen in the rotating section. When separating the organic peroxide reaction liquid, the organic peroxide reaction liquid will be discharged from the discharge pipe through the filter screen, while the solid residue will accumulate on the filter screen. At this time, the cylinder drives the rack to move to the left.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides an organic peroxide reaction liquid separation device, including a separation cylinder 1, a filter screen 2 rotatably connected to the middle of the separation cylinder 1, an adjusting gear 3 fixedly installed at the front end of the filter screen 2, a feed pipe 4 fixedly installed at the right end of the separation cylinder 1, a rotating pipe 5 provided at the top end of the separation cylinder 1, a distribution pipe 6 fixedly installed at the bottom end of the rotating pipe 5, a cylinder 7 fixedly installed at the front side of the separation cylinder 1, a rack 8 fixedly installed at the output end of the cylinder 7, and a discharge pipe 9 fixedly installed at the bottom end of the separation cylinder 1.

[0023] By setting the middle section of the separation cylinder 1 as a rotating section 16 and installing a rotatable filter screen 2 inside the rotating section 16, when separating the organic peroxide reaction liquid, the organic peroxide reaction liquid will be discharged from the discharge pipe 9 through the filter screen 2, while the solid residue will accumulate on the filter screen 2. At this time, the filter screen 2 is rotated 180 degrees, and then the pressure of the gas supplied to the distribution pipe 6 through the gas connection pipe 14 is increased, so that high-pressure gas is sprayed out through the distribution pipe 6, thereby achieving backflushing of the filter screen 2 and cleaning the filter screen 2. The filter screen 2 does not need to be replaced during use, which is low-cost and simple to operate.

[0024] The separator 1 includes a rotating section 16 and a straight section 17. The rotating section 16 is installed in the middle of the straight section 17. The filter screen 2 is rotatably connected inside the rotating section 16, and the cylinder 7 is fixedly installed on the outside of the rotating section 16.

[0025] By setting the separation cylinder 1 at both ends of the rotating section 16 and the straight section 17, the setting of the rotating section 16 enables the filter screen 2 to completely fit against the inner wall of the rotating section 16 when it rotates, and after the filter screen 2 is turned, the horizontal surface of the rotating section 16 can be completely sealed, avoiding the leakage of solid residue through the gap between the two during the filtration and separation time.

[0026] The bottom end of the distribution pipe 6 is located in the inner cavity of the straight section 17, and a nozzle is fixedly installed at the bottom end of the distribution pipe 6.

[0027] By installing nozzles at the bottom of the distribution pipe 6, the gas is uniformly delivered to all parts of the separation cylinder 1, so that the separation cylinder 1 can be cooled evenly.

[0028] The bottom end of the rack 8 meshes with the top end of the adjusting gear 3, and both the rack 8 and the adjusting gear 3 are located on the outside of the rotating section 16.

[0029] Cylinder 7 drives rack 8 to move to the left. Through the meshing of rack 8 with adjusting gear 3, adjusting gear 3 can be rotated 180 degrees, thereby allowing solid residue on filter screen 2 to be poured directly downwards.

[0030] Among them, a motor 10 is fixedly installed at the top of the straight section 17, a drive gear 11 is fixedly sleeved at the output end of the motor 10, and a gear ring 12 is fixedly installed on the surface of the rotating tube 5.

[0031] The motor 10 drives the drive gear 11 to rotate. Through the meshing of the drive gear 11 and the gear ring 12, the distribution pipe 6 can be rotated, so that the high-temperature gas is evenly injected into the separation cylinder 1. The low-temperature gas can be nitrogen or argon, etc.

[0032] The top end of the inner cavity of the rotating tube 5 is provided with a positioning groove 13. The inner cavity of the positioning groove 13 is rotatably connected to a limiting ring 15. The inner cavity of the limiting ring 15 is fixedly installed with a gas connecting pipe 14. The toothed ring 12 meshes with the drive gear 11. The drive gear 11 is located on the right side of the toothed ring 12. The bending direction of the top end of the gas connecting pipe 14 is to the left.

[0033] By setting the limiting ring 15 to slide within the positioning groove 13, the gas connecting pipe 14 and the rotating pipe 5 can be positioned, while ensuring that the rotation of the distribution pipe 6 will not interfere with the connection and installation of the gas connecting pipe 14.

[0034] The rotating tube 5 is rotatably connected to the top of the straight section 17. Two positioning rings are fixedly installed on the surface of the rotating tube 5, and the two positioning rings are located on the upper and lower sides of the top of the straight section 17, respectively.

[0035] By setting two positioning rings, the rotating tube 5 can be positioned at the top of the straight section 17, preventing the rotating tube 5 and the distribution tube 6 from falling downwards.

[0036] Working principle and usage process of this utility model:

[0037] In use, connect the top end of the gas connecting pipe 14 to the gas supply end of the cryogenic gas cylinder, then open the valve of the cryogenic gas cylinder to allow the cryogenic gas to be delivered to the distribution pipe 6 through the gas connecting pipe 14 and the rotating pipe 5, and then injected into the separation cylinder 1 through the distribution pipe 6. At this time, the motor 10 drives the drive gear 11 to rotate. Through the meshing of the drive gear 11 and the gear ring 12, the distribution pipe 6 can be rotated to make the cryogenic gas evenly injected into the separation cylinder 1. The cryogenic gas can be nitrogen or argon, etc. Then, the raw liquid is injected into the separation cylinder 1 through the feed pipe 4. The raw liquid flows downward, and the organic peroxide reaction liquid flows downward through the filter screen 2 and is finally discharged through the discharge pipe 9, while the solid residue remains on the filter screen 2.

[0038] When the solid residue on the filter screen 2 accumulates to the point where it needs to be processed, the supply of raw liquid to the feed pipe 4 is stopped, and the cylinder 7 is activated to drive the rack 8 to move to the left. Through the meshing of the rack 8 and the adjusting gear 3, the adjusting gear 3 can be rotated 180 degrees, thereby allowing the solid residue on the filter screen 2 to be poured directly downwards. Then, the gas pressure entering the gas connection pipe 14 is increased, and high-pressure gas is supplied to the distribution pipe 6 through the gas connection pipe 14, so that high-pressure gas is sprayed out through the distribution pipe 6, thereby achieving backwashing and cleaning of the filter screen 2. After the cleaning is completed, the gas pressure entering the gas connection pipe 14 is adjusted to restore the gas pressure to the normal state, and then the separation and filtration continue.
