Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, one embodiment provided by the present utility model is: the utility model provides a dehydrogenation tower is used in methyl ethyl carbonate production, includes tower body 1, the middle part fixedly connected with motor 2 of tower body 1, the output fixedly connected with threaded rod 3 of motor 2, the top screw thread connection of threaded rod 3 has support column 9, the outside fixedly connected with scraper blade 8 of support column 9, one side fixedly connected with intake pipe 5 of tower body 1, the opposite side fixedly connected with outlet duct 6 of tower body 1, water inlet 10 has been seted up to the bottom of tower body 1, the bottom fixedly connected with rose box 12 of tower body 1. When methyl ethyl carbonate production, methyl ethyl carbonate enters into tower body 1 inside through intake pipe 5 this moment, thereby the inside purifier of rethread dehydrogenation tower is gaseous purifies, thereby the gaseous follow outlet duct 6 discharge after purifying methyl ethyl carbonate for a long time, lead to dehydrogenation tower inside to remain impurity, consequently, need in time clear up the inside residue of assurance dehydrogenation tower, guarantee to carry out subsequent production and use, start motor 2 when needs wash, the output of motor 2 drives threaded rod 3 and rotates this moment, threaded rod 3 is driving support column 9 and is beginning to remove, when support column 9 begins to remove, drive scraper blade 8 and begin to remove, under the restriction of fixed block 7, scraper blade 8 can only carry out the oscilaltion this moment, after carrying out a period of time, the inside residue of dehydrogenation tower can be cleaned up, it can not be delayed to have guaranteed subsequent production.
The middle part of the filter box 12 is connected with a filter screen 13 in a sliding way, and the bottom of the filter box 12 is provided with a water outlet 16. When the waste water in the dehydrogenation tower passes through the filter box 12, the waste water filters harmful components in the waste water through the filter screen 13 in the dehydrogenation tower, and the filtered waste water is discharged from the water outlet 16, so that the discharged waste water is ensured not to influence polluted air, and the safety of staff is ensured.
The limiting groove 4 has been seted up to the inner wall of tower body 1, and scraper 8's outside fixedly connected with fixed block 7, fixed block 7 sliding connection is at the middle part of limiting groove 4. When the user is in the inside of clearance dehydrogenation tower, fixed block 7 can only reciprocate under the influence of spacing groove 4, avoids scraper blade 8 unstable when moving, leads to not closely with the inside contact of tower body 1.
A chute 15 is arranged in the middle of the filter box 12, and the filter screen 13 is slidably connected in the middle of the chute 15. When the user is ready to take out the filter screen 13, the chute 15 can quickly take out the filter screen 13 from the filter box 12, so that the filter screen 13 is not blocked when being detached, and the time is delayed.
The draw-in groove 19 has been seted up in the outside of filter screen 13, and the middle part sliding connection of rose box 12 has pull rod 17, and the outside fixedly connected with spacing ring 20 of pull rod 17, the outside cover of pull rod 17 is equipped with spring 18. When a user prepares to take out the filter screen 13, the pull rod 17 is pulled outwards, so that the other end of the pull rod 17 is pulled out of the filter screen 13, and meanwhile, the limiting ring 20 is contracted from the filter box 12 under the action of the spring 18, so that the filter screen 13 can be taken out for cleaning and replacement, and the subsequent normal use is facilitated.
The outside of the filter screen 13 is fixedly connected with a pull ring 14. When the user wants to draw out the filter screen 13, the filter screen 13 can be quickly taken out by the pull ring 14, so that time and labor are saved.
The bottom of the tower body 1 is fixedly connected with supporting legs 11. When a user uses the device, the supporting legs 11 can fix the tower body 1 on the ground, so that the normal operation of the interior is ensured, and the stability of the tower body 1 in operation is ensured.
Working principle: when methyl ethyl carbonate production, methyl ethyl carbonate enters into tower 1 inside through intake pipe 5 this moment, methyl ethyl carbonate can pass through dehydrogenation tower inside from the purifier who takes with gaseous purification, outwards discharge through outlet duct 6, after using a period, dehydrogenation tower inside persists the impurity this moment, therefore need wash dehydrogenation tower inside, start motor 2 when needs wash, the output of motor 2 drives threaded rod 3 and rotates, threaded rod 3 is driving support column 9 and is beginning to remove, when support column 9 begins to remove, drive scraper blade 8 and begin to remove, under the restriction of fixed block 7, scraper blade 8 only can reciprocate this moment, thereby clear away the impurity of dehydrogenation tower inside, guaranteed that dehydrogenation tower can handle inside residue when using, thereby can normally carry out subsequent production, when scraper blade 8 scrapes the residue on the inner wall of tower 1 to the bottom, this moment can flow into rose box 12 along with waste water through water inlet 10, under the barrier of filter screen 13, filter screen 13 can filter the harmful ingredient in residue and the waste water after handling is discharged through delivery port 16.
After a period of time, because the filter screen 13 filters the gas for a long time to remain a large amount of residues, therefore it is required to wash and replace the filter screen, at this time, the user pulls the pull rod 17 outwards to make the other end of the pull rod 17 pull out from the filter screen 13, and simultaneously the limiting ring 20 contracts from the filter box 12 under the action of the spring 18, at this time, the filter screen 13 can be taken out through the pull ring 14, otherwise, the filter screen 13 can be installed, and the use is convenient.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
