Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering and separating device for producing vinylene carbonate. Background Art

[0002] The chloroethylene carbonate mixed liquid is measured in a metering tank and then placed in a synthesis reactor. A certain amount of solvent dimethyl carbonate DMC and triethylamine (including recovered triethylamine TEA) are pumped from a storage tank into respective metering tanks and then placed in the synthesis reactor in sequence after measurement. The substance generated after the reaction in the synthesis reactor is a mixture of dimethyl carbonate and vinylene carbonate mixed liquid and solid triethylamine hydrochloride.

[0003] The mixed liquid of dimethyl carbonate and vinylene carbonate obtained by filtration separation is pumped into a distillation device, so the removal process of solid triethylamine hydrochloride is particularly important. The existing filtration device is generally in a fixed state, so the filtration process needs to rely on gravity to achieve, and as the work continues, the mesh of the filter will gradually be blocked, and then the filtration efficiency will gradually decrease. Therefore, a filtration separation device for vinylene carbonate production is proposed. Summary of the invention

After the mixed liquid enters the transition cover, it will enter the multiple filter tubes at the bottom. The solid triethylamine hydrochloride will be blocked, and the liquid will flow through the filter holes of the filter tube to the outside. The motor outside the installation tank is started, and the motor shaft drives the helical gear to rotate. The helical gear will drive the transition cover to rotate inside the installation ring through the helical gear ring meshing with it, and then the multiple filter tubes will also rotate synchronously with the transition cover. The filter tube is eccentrically installed, and its rotation can achieve the effect of increasing the centrifugal force. The liquid inside the filter tube will be separated faster under the action of centrifugal force.

[0008] As a further preferred embodiment of the present technical solution, a sealing cover is threadedly connected to the bottom of the circumferential outer wall of each of the plurality of filter tubes.

[0009] As a further preferred embodiment of the present technical solution, a scraping assembly is installed inside each of the filter tubes, and the scraping assembly includes a connecting frame rotatably connected to the top of the circumferential inner wall of the filter tube, a gear ring 2 is fixedly connected to the top outer wall of the connecting frame, and two scraping strips are fixedly connected to the bottom outer wall of the connecting frame, and both of the scraping strips are in contact with the circumferential inner wall of the filter tube.

[0012] As a further preferred embodiment of the present technical solution, a plurality of the bottom fixing sleeves of the filter tubes are provided with a stabilizing frame, and the stabilizing frame is rotatably connected to the circumferential inner wall of the mounting tank.

[0013] As a further preferred embodiment of the present technical solution, a liquid inlet hopper is fixedly connected to the outer wall of the top of the installation tank, and one end of the bottom of the liquid inlet hopper is located at the bottom of the second gear ring.

[0024] A helical gear ring 503 is fixedly sleeved in the middle of the circumferential outer wall of the transition cover 501, a motor 504 is fixedly mounted on the circumferential outer wall of the mounting tank 1, a helical gear 505 is coaxially fixed to the output end of the motor 504, and the helical gear 505 is meshed with the helical gear ring 503.

[0025] The bottom of the circumferential outer wall of each of the plurality of filter tubes 502 is threadedly connected with a sealing cover 506, so that the installation and removal process of the sealing cover 506 is more convenient, thereby ensuring that the filtered solids are discharged more conveniently.

[0026] After the mixed liquid enters the transition cover 501, it will enter the multiple filter tubes 502 at the bottom, and the solid triethylamine hydrochloride will be blocked, while the liquid will pass through the filter holes of the filter tube 502 and flow to the outside. The motor 504 outside the installation tank 1 is started, and the motor 504 shaft drives the bevel gear 505 to rotate. The bevel gear 505 will drive the transition cover 501 to rotate inside the installation ring 2 through the bevel gear ring 503 meshing with it, and then the multiple filter tubes 502 will also rotate synchronously with the transition cover 501. The filter tube 502 is eccentrically installed, and its rotation can achieve the effect of increasing the centrifugal force. Under the action of centrifugal force, the liquid inside the filter tube 502 will be separated from it faster.

[0027] like Figure 2 and Figure 3 As shown, a scraping assembly 6 is installed inside each of the multiple filter tubes 502. The scraping assembly 6 includes a connecting frame 601 rotatably connected to the top of the circumferential inner wall of the filter tube 502, a gear ring 2 603 is fixedly connected to the top outer wall of the connecting frame 601, and two scraping strips 602 are fixedly connected to the bottom outer wall of the connecting frame 601. The two scraping strips 602 are both in contact with the circumferential inner wall of the filter tube 502.

[0028] A plurality of extension strips 605 distributed at equal distances are fixedly connected to the inner circumferential wall of the mounting tank 1 , and the plurality of extension strips 605 are fixedly connected to the same gear ring three 604 , and the plurality of gear rings two 603 are all meshed with the gear ring three 604 .

[0029] The connecting frame 601 will also perform circular motion with the filter tube 502. The tooth ring 2 603 fixed on the top of the connecting frame 601 will rotate while revolving in coordination with the tooth ring 3 604 meshing with it. At this time, the connecting frame 601 will also drive the scraping strip 602 to rotate inside the filter tube 502. The scraping strip 602 can scrape off the triethylamine hydrochloride attached to the inner wall of the filter tube 502, thereby ensuring that the filtering effect of the filter tube 502 can be maintained continuously.

The mixed liquid is poured into the liquid inlet hopper 4, and then falls into the transition cover 501 from the opening at the bottom of the liquid inlet hopper 4, thereby preventing the mixed liquid from touching the gear ring 603 and causing corrosion.

[0032] The utility model provides a filtering and separating device for vinylene carbonate production, and the specific working principle is as follows:

[0033] When the device is working, the mixed liquid is poured into the liquid inlet bucket 4, and then falls into the transition cover 501 from the opening at the bottom of the liquid inlet bucket 4, so as to prevent the mixed liquid from touching the gear ring 2 603 and causing corrosion. After the mixed liquid enters the transition cover 501, it will enter the multiple filter tubes 502 at the bottom, and the solid triethylamine hydrochloride will be blocked, while the liquid will pass through the filter holes of the filter tube 502 and flow to the outside. The motor 504 outside the installation tank 1 is started, and the rotating shaft of the motor 504 drives the bevel gear 505 to rotate. The bevel gear 505 will drive the transition cover 501 to rotate inside the installation ring 2 through the bevel gear ring 503 meshing with it, and then the multiple filter tubes 502 will also follow the transition cover 5 01 rotates synchronously, and the filter tube 502 is eccentrically installed, and its rotation can achieve the effect of increasing the centrifugal force. The liquid in the filter tube 502 will be separated faster under the action of centrifugal force. During this period, the connecting frame 601 will also follow the filter tube 502 to perform circular motion, and the tooth ring 2 603 fixed on the top of the connecting frame 601 will rotate while revolving in cooperation with the tooth ring 3 604 engaged with it. At this time, the connecting frame 601 will also drive the scraping strip 602 to rotate inside the filter tube 502, and the scraping strip 602 can scrape off the triethylamine hydrochloride attached to the inner wall of the filter tube 502, thereby ensuring that the filtering effect of the filter tube 502 can be maintained continuously.
