Description

Technical Field

[0001] This utility model belongs to the technical field of stirring devices, and in particular relates to a raw material proportioning and stirring device for the production of biochemical reagents. Background Technology

[0002] In the field of biochemical reagent production, because most raw materials for biochemical reagents are in powder form (such as enzyme preparations, buffer salts, and colorimetric agents) or liquid form (such as solvents and catalysts), and the proportions of raw materials vary greatly in different reagent formulations, with some raw materials requiring extremely high precision in dosage, precise control of raw material proportions is necessary to ensure reagent efficacy. Most small and medium-sized biochemical reagent manufacturers still use the traditional manual weighing-feeding method to complete raw material proportioning: operators must weigh each raw material one by one using an electronic balance according to the production formula, record the weighing data, and then pour the weighed raw materials into a mixing tank in sequence, finally mixing the raw materials using a stirring device. While this operating mode can meet the proportioning requirements to a certain extent, it has significant labor cost issues, resulting in high labor input and high labor costs. Utility Model Content

[0022] The motor, weight sensor, liquid level sensor, and electric telescopic rod 32 in the device are all electrically connected to an external controller. The valve can be an electrically controlled valve connected to the controller, or it can be a manually controlled valve. This is existing technology and will not be described in detail.

[0023] The working principle of this utility model is as follows: When it is necessary to mix ingredients, solid raw materials in the form of blocks or powders are weighed by the solid ingredient mixing component 2 and then put into the mixing tank 1. Liquid raw materials are measured by the liquid ingredient mixing component 3 and then put into the mixing tank 1. Multiple sets of solid ingredient mixing components 2 and liquid ingredient mixing components 3 can mix multiple raw materials at the same time.

[0024] Before use, set the weight value of the weight sensor as needed. Then, move the liquid level sensor 33 to the position of the required liquid volume by the electric telescopic rod 32. This operation is all set in advance by an external controller.

[0025] Solid materials enter the weighing barrel 23 through the feed inlet 22. The weight sensor detects the weight. When the raw material reaches the standard, the controller closes the valve of the feed inlet 22. Then, the third motor 29 drives the third threaded rod 28 to rotate, thereby moving the weighing barrel 23 and the bottom plate 24 to the discharge port 25. Due to gravity, the bottom plate 24 rotates downward and the material falls. The first motor 56 drives the first drive gear 55 to rotate, thereby driving the first driven gear 54 to rotate, which in turn drives the first threaded rod 57 to move downward. The first scraper 52 connected to the first threaded rod 57 moves downward, and the first scraper 53 scrapes the material from the inner wall of the weighing barrel 23 and it falls into the mixing tank 1 due to gravity, preventing the material from adhering to the inner wall of the weighing barrel 23 and thus affecting the raw material ratio of the biochemical reagent.

[0026] Liquid material enters the measuring tank 31 through the inlet. When the liquid level sensor 33 contacts the screen, the controller closes the valve of the inlet and opens the valve of the outlet pipe 34. The liquid enters the mixing tank 1. Then, the second motor 66 drives the second drive gear 65 to rotate, thereby rotating the second driven gear 64, which in turn drives the second threaded rod 67 to move down. The second scraper 62 connected to the second threaded rod 67 moves down, and the second scraper 63 scrapes the inner wall of the measuring tank 31 to prevent the liquid from adhering to the inside of the measuring tank 31.

[0027] After the materials are mixed in a fixed ratio, the fourth motor 43 drives the stirring shaft 41 and stirring rod 42 to rotate. After the reaction is completed, the materials are discharged from the outlet 11.

[0028] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
