Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production recovery, and in particular relates to a chemical production recovery device. Background Art

[0002] In production and life, high-efficiency and high-concentration drugs are often diluted with several times or a small amount of water to a higher concentration solution, namely the mother solution. When used, the remaining amount of water is added to the diluted concentration. Such a step-by-step dilution can make the drug solution mix more evenly and the diluted concentration more accurate. In chemical production, an important process is to recover the mother solution.

[0003] For example, the Chinese patent with publication number CN217613351 U discloses a mother liquid recovery device for chemical production and processing, which includes a bracket and a recovery chamber. A filter bucket is arranged on the upper part of the recovery chamber, and connecting ears are arranged on both sides of the filter bucket. The lower ends of the connecting ears are connected to the vibration motor through a connecting assembly and a connecting plate; a cover body is arranged on the upper end of the filter bucket, and a liquid inlet is arranged on the cover body; a stirring assembly is arranged on the lower end of the recovery chamber, and the stirring assembly includes a rotating shaft, one end of the rotating shaft is provided with a driving device connection, and the other end is arranged on the inner wall of the recovery chamber, and a stirring rod is arranged on the rotating shaft, and a cleaning brush assembly is arranged at the end of the stirring rod; and a liquid outlet is arranged at the lower end of the recovery chamber. The utility model provides a mother liquid recovery device for chemical production and processing, which is cleverly designed and easy to use. It can quickly filter and recover the mother liquid, and can also effectively prevent the mother liquid from precipitating after being left standing for a long time.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when the device is recycling the mother liquor, due to the large gaps between the multiple stirring rods, the mother liquor cannot be fully stirred, so that the mother liquor will still precipitate after stirring. In addition, after the device filters the mother liquor, the filtered crystals will remain in the filter bucket, which is inconvenient for personnel to clean it, thus affecting the next use of the filter bucket. In view of this, we propose a chemical production recovery device. Utility Model Content

[0006] The purpose of the utility model is to provide a chemical production recovery device to solve the problems raised in the above background technology.

[0011] A power assembly is located in the recovery box and is used to drive the first stirring rod and the four second stirring rods to rotate.

[0012] In the technical solution, the filter net is set up, and the filter net can filter the mother liquor, and the crystals in the mother liquor can be filtered. After the filtering is completed, the mother liquor will flow to the bottom of the cavity. At this time, the power assembly can be driven by the power assembly, and the power assembly drives the stirring rod one and the four stirring rods two to rotate. The stirring rod one and the four stirring rods two rotate to fully stir the mother liquor in the cavity. At the same time, since the round rods on the stirring rod one and the stirring rod two are staggered, in the process of stirring the mother liquor, all the mother liquor in the cavity can be fully stirred to ensure that the mother liquor will not precipitate.

[0013] Through the set sealing assembly, the sealing assembly can open the collection tank, and then the personnel can start the electric push rod. The output shaft of the electric push rod will drive the scraper to move on the top surface of the filter. The movement of the scraper can scrape off the crystals remaining on the top of the filter. The scraped crystals will fall into the collection box and then be collected together to ensure that after the mother liquor is filtered, the crystals remaining on the top of the filter can be cleared in time to ensure that no crystals remain when the filter is used next time.

The upward movement of the sliding plate will squeeze the spring to shrink. At the same time, the baffle will move upward in the rectangular groove until the bottom of the baffle is higher than the top of the recycling box. The person can turn the pull rod. At this time, the bottom end of the pull rod will rotate on the sliding plate. The rotation of the pull rod will drive the baffle to rotate until the baffle rotates 90°. At this time, the person can release the pull rod. Under the action of the spring rebound force, the spring will squeeze the sliding plate to make the sliding plate move downward and drive the pull rod to move downward. The movement will drive the baffle to move downward until the bottom of the baffle rests against the top of the recycling box. The baffle can limit the pull rod. At this time, the sliding plate can open the collection tank. Then the personnel can start the electric push rod. The output shaft of the electric push rod will drive the scraper to move on the top surface of the filter. The movement of the scraper can scrape off the crystals remaining on the top of the filter. The scraped crystals will fall into the collection box and then be collected together to ensure that after the mother liquor is filtered, the crystals remaining on the top of the filter can be removed in time to ensure that no crystals remain when the filter is used next time.

A motor is fixedly installed at the bottom of the recycling box, and the output end of the motor passes through the bottom of the recycling box, extends into the rotating groove and is coaxially connected to the gear.

[0021] In the present technical solution, the motor is started, and the output shaft of the motor drives gear one to rotate in the rotating groove. Under the action of meshing, the rotation of gear one will drive the four gear twos to rotate. At the same time, the rotation of gear one will drive the stirring rod one to rotate, and the rotation of the four gear twos will respectively drive the four stirring rods two to rotate. The rotation of stirring rod one and the four stirring rods two can fully stir the mother liquor in the cavity. At the same time, since the round rods on stirring rod one and stirring rod two are staggered, during the process of stirring the mother liquor, all the mother liquor in the cavity can be fully stirred to ensure that the mother liquor will not precipitate.
