Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a chemical experimental mixing device. Background Technology

[0002] Currently, the main method for adding chemical reagents in chemical experiments is to use droppers or burettes. After the chemical reagents are added, they need to be mixed using a mixing device, which requires a chemical experiment mixing device.

[0003] For example, CN223055465U discloses a rapid mixing device for chemical reagents in the field of chemical reagent mixing technology. It includes a mixing tank with connection holes on both sides of its top. A top cover is installed on the top of the mixing tank, and a stirring assembly is located in the center of the top of the top cover. An installation groove is provided on the top cover, which is adapted to the top of the mixing tank. The connection assembly on both sides of the top cover includes a connection groove. A connecting rod is fixedly installed on one side of a sliding plate in the connection groove, and the connecting rod corresponds to the connection hole. The other two ends of the sliding plate are connected to the inner wall of the connection groove via springs. A pull rod fixedly installed in the center of the other side of the sliding plate passes through the side wall of the connection groove and is slidably connected to the connection groove. This invention utilizes the adaptation of the connecting rod and the connection hole in the connection assembly to achieve a detachable connection between the top cover and the mixing tank. This allows the stirring assembly to be easily removed and the attached reagents cleaned after the reagents are mixed.

[0004] Although the aforementioned patent allows for easy removal of the stirring component to clean the adhering reagents after the reagents are mixed, the prior art of the patent requires the stirring component to be removed to clean the adhering reagents, which is a cumbersome process and reduces its practicality.

Several stirring paddles 502 are fixed on the outside of the rotating tube 501. Water outlet pipes 503 are connected to both the left and right sides of the rotating tube 501. Several nozzles 504 are connected to the upper, lower, front, and rear sides of the water outlet pipes 503 on both the left and right sides. Two connecting rods 505 are fixed to both the left and right sides of the rotating tube 501. An L-shaped scraper 506 is fixed to the opposite side of the connecting rods 505 on both the left and right sides. The top end of the rotating tube 501 rotatably passes through the mixing tank 1 and extends to the upper side. A driving component is provided on the upper surface of the mixing tank 1. The top end of the rotating tube 501 is rotatably connected to a connecting pipe 509 via a sealed bearing.

[0030] Specifically, chemical experimental raw materials are added through the feed pipe on the left side of the upper surface of the mixing tank 1. After the feeding is completed, the second sealing cover is closed to ensure sealing. Then, the motor 507 is started, and the motor 507 drives the rotating tube 501 to rotate. The stirring paddle 502 on the outside of the rotating tube 501 rotates accordingly to stir the chemical experimental raw materials in the tank and make them fully mixed. After that, the material can be discharged by opening the valve in the discharge structure 3.

[0031] Specifically, the driving component includes a motor 507 mounted on the upper surface of the mixing tank 1 via a mounting bracket. A transmission wheel 508 is fixed to the outer side of the output shaft of the motor 507 and the outer side of the top of the rotating tube 501.

The lower surfaces of the L-shaped scrapers 506 on both the left and right sides are in contact with the bottom wall of the inner cavity of the mixing tank 1. When the rotating tube 501 rotates, it can drive the L-shaped scrapers 506 on both the left and right sides to scrape off the impurities attached to the inner circumferential wall of the mixing tank 1.

[0032] It should be noted that water is dispensed through several nozzles 504 on the left and right sides, and with the rotation of the water outlet pipes 503 on the left and right sides, the inside of the mixing tank 1 can be cleaned, improving the convenience of cleaning.

[0033] Please see Figure 4 In this embodiment, the heating component 6 includes a water tank 601 fixed on the right side of the mixing tank 1.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, chemical experimental raw materials are added through the feed pipe on the left side of the upper surface of the mixing tank 1. After feeding is completed, the second sealing cover is closed to ensure a seal. Then, the motor 507 is started, which drives the rotating tube 501 to rotate. The stirring paddle 502 on the outside of the rotating tube 501 rotates accordingly, stirring the chemical experimental raw materials in the tank to ensure thorough mixing. Afterward, the material can be discharged by opening the valve in the discharge structure 3. When the rotating tube 501 rotates, it can drive the L-shaped scrapers 506 on both sides to clean the residue adhering to the inner circumferential wall of the mixing tank 1. When scraping away impurities and cleaning the inside of the mixing tank 1, the water pump 605 can be turned on to transport water from the water tank 601 to the water outlet pipes 503 on both sides through pipes. Then, water is sprayed out through several nozzles 504 on both sides. With the rotation of the water outlet pipes 503 on both sides, the inside of the mixing tank 1 can be cleaned. During cleaning, the water in the water tank 601 can be heated by the heating wire 602, and then the inside of the mixing tank 1 can be cleaned with hot water, which improves the convenience of cleaning.
