Description

TECHNICAL FIELD

[0001] The utility model relates to a powder mixing system with good sealing performance belongs to powder mixing technical field. BACKGROUND

[0002] The mixing process of powder is that different component materials are uniformly distributed under the action of external force, which is a necessary process for optimizing the performance of powder materials.

[0003] The raw materials are sent into the mixing bin after metering from the feeding bin, and are uniformly mixed through stirring, overturning and shearing in the mixing bin. After mixing, the mixed materials are sent out of the system through the receiving bin for subsequent process.

[0004] When the material is fed or discharged in the mixing bin, the connected equipment will produce a large amount of exhaust due to the change of the volume of the material in the equipment. These gases will leak from the weak sealing part, causing dust overflow. Even if there is no leakage, it will also cause a large pressure to the sealing system of the equipment. The management of dust during the mixing process is related to the occupational health of the on-site personnel, the on-site environment, the stable operation of the equipment, the quality and cost of the mixing process. Reducing dust leakage can bring multiple benefits.

[0005] As can be seen from the above, the prior art has obvious inconvenience and defects in actual use, and therefore needs to be improved. CONTENT OF THE UTILITY MODEL

[0006] The utility model provides a powder mixing system with good sealing performance to solve the problem of dust leakage caused by poor exhaust of the equipment during the mixing process by increasing the exhaust path.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme:

[0008] A powder mixing system with good sealing performance comprises a feeding bin, a mixing bin and a receiving bin which are sequentially connected in the longitudinal direction.

[0009] A first communication pipeline is installed between the top of the feeding bin and the top of the mixing bin, and a first communication valve is installed on the first communication pipeline. A second communication pipeline is installed between the top of the mixing bin and the top of the receiving bin, and a second communication valve is installed on the second communication pipeline.

[0010] A bag filter and a dust collector are installed above the mixing bin, and a third communication valve is installed at the connection between the bag filter and the mixing bin.

[0011] Further, a first discharge valve is installed at the connection between the feeding bin and the mixing bin.

[0012] Further, a second discharge valve is installed at the connection between the mixing bin and the collecting bin.

[0013] Further, the air inlet of the dust collector is connected with the top of the inner cavity of the mixing bin through a dust removal pipeline.

[0014] Further, a fourth communication valve is installed on the dust removal pipeline.

[0015] Further, the bottom outlet of the dust collector is connected with the top of the inner cavity of the mixing bin through a reflux pipeline.

[0016] Further, a third discharge valve is installed at the connection between the reflux pipeline and the dust collector.

[0017] The above technical scheme is adopted in the utility model, compared with the prior art, has the following advantages:

[0018] The utility model discloses a gas discharge path is added, solves the problem that the dust leaks out of the equipment due to poor exhaust during the mixing process, and the gas discharge path includes communication exhaust, bag exhaust and dust removal exhaust.

[0019] The gas discharged by the collecting bin and the mixing bin flows in the equipment through the communication pipeline, and more gas is not discharged, so that the pressure of the dust seal and the air seal of the mixing system is reduced. When the communication exhaust effect between the equipment is poor, the third communication valve is opened, and the gas in the mixing bin that is not timely discharged can be discharged through the bag filter. When the communication exhaust and the bag exhaust cannot achieve the expected effect, the dust can be collected by the dust collector and returned to the mixing bin in time.
