Technical Field

[0001] The utility model relates to the technical field of laboratory raw material proportioning, and particularly relates to a quantitative batching device for laboratory raw materials. Background Art

[0002] There are various raw materials in the laboratory. When conducting experiments, it is necessary to reasonably proportion the raw materials according to their usage conditions and combination conditions. Therefore, some tools are needed to assist in batching.

[0003] The existing quantitative batching devices for raw materials usually carry out reasonable proportioning by weighing or measuring volume. After the proportioning is completed, different raw materials will be stirred inside the device. After the stirring is completed, the mixed materials are discharged to complete the batching work. However, during the stirring process, the raw materials are likely to remain inside the device, and the remaining raw materials will cause the actual proportion of the next batching to be damaged, thereby affecting the quality of the batching.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a raw material quantitative batching device for laboratory use, including a base 1, a mixing tank 2 fixedly connected to the top of the base 1, a mixing pipe 3 rotatably connected to the inside of the mixing tank 2, a water supply pipe 4 slidably connected to the inside of the mixing pipe 3, mixing blades 5 fixedly connected to the outer wall of the mixing pipe 3, a first scraper 6 fixedly connected to the side of the mixing blade 5 away from the mixing pipe 3, the first scraper 6 being slidably connected to the inner wall of the mixing tank 2, water supply holes 7 provided inside the water supply pipe 4, flushing holes 8 provided inside the mixing pipe 3, a fixed box 9 fixedly connected to the top of the mixing tank 2, and a first motor 10 fixedly installed inside the fixed box 9.

[0022] In an alternative embodiment: The output end of the first motor 10 is fixedly connected with a driving bevel gear 11. The driving bevel gear 11 is meshed and connected with a driven bevel gear 12. The driven bevel gear 12 is fixedly connected with the outer wall of the stirring tube 3. The top of the fixed box 9 is fixedly connected with a sliding box 13. A rotary joint 14 is slidably connected inside the sliding box 13. The bottom of the rotary joint 14 is fixedly connected with the top of the water supply pipe 4. The top of the rotary joint 14 is fixedly connected with a flushing pipe 15. The top of the sliding box 13 is fixedly connected with a threaded pipe 16. The outer wall of the flushing pipe 15 is threadedly connected with the threaded pipe 16. A handle 17 is fixedly connected to the outer wall of the flushing pipe 15.

[0023] It should be noted that after the batching is completed, the first motor 10 can drive the driving bevel gear 11 to rotate, so that the driving bevel gear 11 drives the driven bevel gear 12 to rotate, thereby enabling the driven bevel gear 12 to drive the stirring tube 3 to rotate and using the stirring blades 5 to mix and stir the raw materials after batching. When the inside of the device needs to be cleaned after use, first rotate the flushing pipe 15 with the handle 17, so that the threaded connection part of the flushing pipe 15 slides upward, thereby driving the rotary joint 14 to slide upward inside the sliding box 13, and then driving the water supply pipe 4 to slide upward inside the stirring tube 3, achieving the effect of aligning the water supply holes 7 with the flushing holes 8. Subsequently, connect the water source to the flushing pipe 15 and then start the first motor 10, so that the water passes through the flushing pipe 15, the rotary joint 14, the water supply pipe 4 and the water supply holes 7 and then sprays out from the flushing holes 8. When the first motor 10 drives the stirring tube 3 to rotate, the sprayed water flow cooperates with the rotating first scraper 6 to scrape the inner wall of the mixing tank 2, thereby preventing raw materials from remaining on the inner wall and avoiding the influence of residues on subsequent proportioning.

[0024] In an alternative embodiment: One side of the top of the mixing tank 2 is fixedly connected with a powder box 18. There is a first scale 19 on one side of the powder box 18. A first rotating rod 20 is rotatably connected inside the powder box 18. A second motor 21 is fixedly installed on the top of the powder box 18.

A third motor 24 is fixedly installed on the top of the liquid box 22. A second rotating rod 25 is rotatably connected inside the liquid box 22. The output end of the third motor 24 is fixedly connected with the second rotating rod 25. Second scrapers 26 are fixedly connected to the sides of the first rotating rod 20 and the second rotating rod 25. A spiral blade 27 is fixedly connected to the bottom of the first rotating rod 20. The bottom of the powder box 18 is fixedly connected with a first connecting pipe 29. A first solenoid valve 28 is provided inside the first connecting pipe 29. The bottom of the liquid box 22 is fixedly connected with a second connecting pipe 31. A second solenoid valve 30 is provided inside the second connecting pipe 31.

[0025] It should be noted that the first scale 19 and the second scale 23 can observe the amount of raw materials entering the powder box 18 and the liquid box 22. After the proportioning is completed, opening the first solenoid valve 28 and the second solenoid valve 30 allows the raw materials to enter the interior of the mixing tank 2. At this time, the second motor 21 is started to drive the spiral blade 27 at the bottom to rotate, so that the solid raw materials are slowly conveyed downward under the action of the spiral blade 27, thereby preventing the solid raw materials from being added to the liquid at one time and causing caking, and further improving the effect of raw material mixing and batching.

[0026] In an alternative embodiment: A discharge pipe 32 is fixedly connected to the bottom of the mixing tank 2. A valve 33 is provided inside the discharge pipe 32. A water inlet pipe 34 is fixedly connected to the top of the mixing tank 2. A viewing window 35 is provided on one side of the mixing tank 2. A control panel 36 is fixedly installed on the outer wall of the mixing tank 2. The control panel 36 is electrically connected to the first motor 10, the second motor 21, the third motor 24, the first solenoid valve 28, and the second solenoid valve 30.
