Description
Technical Field
The utility model belongs to the technical field of the colloid production, specifically a send and grind integrative device of colloid powder.
Background
In the prior art, raw materials such as sealant, masonry glue and the like contain quartz micro powder, silicon micro powder and/or carbon black micro powder and the like. These powders are mixed with resins or other colloids to give products. Here, it is necessary that these fine powder particles are sufficiently uniform and small to ensure a high quality of the product. The fineness of the micro powder is detected by a special instrument and a specific method (a laser diffraction scattering method, a centrifugal sedimentation method and the like) generally in a laboratory environment. The powder raw materials are purchased in factories, and the fineness of the powder is determined through detection reports provided by suppliers. Due to the restriction of various objective factors such as storage and transportation, the fineness of the powder material is more or less uneven or caked, which affects the quality of the final product and increases the production cost (for example, the stirring time needs to be increased).
Disclosure of Invention
In order to solve the above problems existing in the prior art, the utility model provides a colloid powder send and grind integrative device. The background of the development of the device is that in the current production practice, powder is directly put into a mixing machine such as a kneader and the like through a hopper. The powder material of most products, because of its very small size, is in a fluid form (like toner for laser printers). If the powder can be directly fed into a mixing machine through a sealed pipeline in a closed space, the powder can be directly fed into the mixing machine through the sealed pipeline, and the dust pollution of a production site can be reduced. And the grinding device is added in the feeding pipeline, so that the caking problem can be solved to a certain extent, and the powder can be ground for the second time. Based on the above thought, the utility model discloses a technical scheme as follows:

The utility model has the principle that the impeller vacuum pump can be adopted to convey powder with high density, fine particles and fluid shape to replace the traditional auger. From a cost perspective, the impeller vacuum pump is lower than the auger. Since the powder itself is fine and the hardness of the agglomerates is low even if they agglomerate, the power requirement of the grinding apparatus is not high, for which the grinding function can be safely realized with a small power of the part from which the vacuum pump can be divided. A more powerful motor may also be used as appropriate.
The convex edge on the bottom surface of the first grinding plate rotates at high speed with the first grinding plate, and then pressure difference similar to the pressure difference between the center and the periphery of the impeller is generated, so that powder enters from the middle of the first grinding plate (the hollow part of the second grinding plate) and exits from the outer edge of the first grinding plate and is sucked by the vacuum pump.
The opening of the feed inlet of the hopper faces upwards, the opening of the feed inlet of the vacuum pump faces downwards, and a closed space is formed between the feed inlet of the hopper and the feed inlet of the vacuum pump after the feed inlet of the vacuum pump is filled with materials, so that the feeding efficiency is improved.
Because the discharge of the vacuum pump in the closed pipeline is in a jet shape, if the powder is directly sent to the mixing machine, the powder can be raised, and the like, therefore, the discharge hole of the feeding pipe is connected with the pressure relief cabin, so that the powder can freely fall in the pressure relief cabin and can slide into the feeding of the mixing machine.

Further, in a group of feed grinding units: a corresponding key connection structure is arranged between the front part of the rotating shaft of the vacuum pump and the impeller; the front part of a rotating shaft of the vacuum pump is provided with an external thread, and a nut is screwed on the external thread;
an inner hexagonal groove is formed in the nut, a hexagonal prism is arranged at the top end of the driving shaft, and the hexagonal prism is detachably inserted into the inner hexagonal groove.
Further, the inner diameter of the second grinding plate is not less than the inner diameter of a feed port of the vacuum pump; the inner cavity of the shell at the position of the first grinding plate and the second grinding plate is in a bulge shape. The scheme is used for ensuring the flow rate of the vacuum pump.
Adopt this structure, easy dismounting, if the condition such as grinder card hinders has appeared moreover, the nut and hexagonal prism these parts of being convenient for maintain and change of at first damaging. The connection structure of the inner hexagonal groove/the hexagonal column has higher fault tolerance on the length of the driving shaft. The direction of the external thread, the rotation direction of the impeller and the rotation direction of the first grinding plate (convex edge) are matched, so that when all parts rotate along with the motor of the vacuum pump, the screw cap and the external thread attract each other, the impeller sucks materials, and the first grinding plate discharges materials to the periphery.
