Description

Background technique

In the field of solid-liquid mixing preparation of real stone paint, mortar, putty, detergent, grease, emulsified asphalt, adhesive, etc., it is necessary to first calculate the ratio between each solid and liquid according to the capacity of the stirring mechanism, and then add the quantitative solid and liquid materials directly or through conveying equipment into the mixing tank for stirring and mixing. Since the single input amount is large, a single mixing requires a long time; after mixing, the mixing tank needs to be cleaned, especially for the two materials of different materials or colors, which need to be cleaned more carefully. Since the mixing tank is large, it requires more manpower, material resources and water resources.

Most of the existing conveying equipment adopts a single-machine one-way device, that is, each set of conveying equipment can only convey materials in one direction. When it is necessary to convey in the opposite direction, the entire conveyor must be turned or connected through a pipeline, which is very inconvenient. Moreover, the conveying principle of the conveyor is to convey the material in the pipeline forward through the rotation of the spiral blades. At the same time, the rotation of the blades when the material enters the pipeline easily causes a gap between the spiral blades and the material, resulting in insufficient material passing through the pipeline cross section. It is difficult to measure the conveying volume of the material, that is, it is difficult to control the volume ratio of the powder and the adhesive.

The output shaft of the motor sequentially passes through the bottom of the stirring tank 604, the second dispersion plate 603 and the first dispersion plate 602. The motor The output shaft of the machine is provided with a sealed bearing to intersect with the mixing bin 604 and the end cover 601.

The mixing and stirring mechanism 6 in this embodiment is relatively small in size and adopts a mixing and discharging operation mode, which not only reduces the motor power in the mixing operation, but also improves the mixing efficiency. The mixing principle of the liquid material and the solid material is that the solid material falling on the first dispersion plate 602 is rotated at high speed by the first dispersion plate 602 to the inner wall of the mixing chamber 604, and the solvent liquid falls on the second dispersion plate 603. Similarly, after high-speed rotation, the liquid material is mixed with the solid material spun off from the first dispersion plate 602 before flying to the inner wall of the mixing chamber 604. This is the first-level mixing of solid and liquid; the solid and liquid after the first-level mixing fall on the impact shearing of the shear emulsification blade 607 on the second dispersion plate 603, and the second-level mixing is carried out and falls between the bottom surface of the mixing chamber 604 and the second dispersion plate 603. Under the scraping of the second scraper, the solid and liquid materials not only move to the discharge port, but also undergo the third-level mixing, and finally are discharged from the discharge port, that is, the finished product.

The working process of the multifunctional mixing and stirring system described in the present invention is as follows: when the material to be mixed is a solid-solid material, the material to be mixed is placed in the feed hopper 2, the material is lifted by the elevator 1 and transported to the storage box 3, and the material in the storage box 3 falls into the conveying mechanism 4 under the rotation of the spiral blade or due to the action of gravity, and the motor at the second discharge port 402 works, and the solid-solid material is discharged from the second discharge port 402 and enters the feed hopper 2 at the elevator 1, thereby completing a mixing cycle, and such a cycle realizes solid-solid mixing;

When the materials to be mixed are multiple solid materials and liquid materials are required as adhesives, the solid-solid material mixing process is the same as the solid-solid material mixing process described above. After the solid materials are evenly mixed, the motor at the first discharge port 401 starts working, and the materials in the circulation mechanism are discharged from the first discharge port 401 into the mixing and stirring mechanism 6. At the same time, the solid materials that have been mixed and stirred evenly are added to the conical funnel at the feeding port 404 to be used as spare materials to feed the conveying mechanism 4, so as to ensure that the materials in the shell of the conveying mechanism 4 are always in a full state; when the fully mixed solid materials enter the mixing and stirring mechanism 6, the liquid materials enter the mixing and stirring mechanism 6 from the injection pipe on the solvent tank 5 through the metering pump 501, and are mixed with the fully mixed solid materials, and finally discharged from the discharge port on the mixing and stirring mechanism 6, which is the finished product. The amount of solid materials input into the mixing and stirring mechanism 6 can be quickly calculated by the cross-section of the mixing and stirring mechanism 6, the motor speed and the output time. At the same time, the liquid materials entering the mixing and stirring mechanism 6 are set by the metering pump 501, so that the solid and liquid materials can be added quantitatively according to the ratio.

The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
