Cement material conveying bin pump

Abstract

The invention relates to a cement material conveying bin pump which comprises a conveying bin, a dust removal separator, a negative pressure feeding mechanism, a negative pressure air outlet mechanism, a positive pressure air inlet mechanism, a positive pressure air outlet, a separator conical hopper, an output mechanism and a support. A negative-pressure air outlet mechanism is installed in the middle of the upper end of the dust removal separator, a positive-pressure air inlet mechanism is connected between the dust removal separator and the conveying bin, a positive-pressure air outlet is formed in the front side of the upper end of the dust removal separator, a separator conical hopper is installed at the lower end of the conveying bin, and an output mechanism is installed at the lower end of the separator conical hopper. Supports are evenly installed on the separator conical hopper in the circumferential direction of the separator conical hopper. The device can solve the problems that under negative pressure conveying, along with gas input, dust raising is likely to be caused, part of materials can float under pushing of gas, and the entering materials are difficult to rapidly and completely collect.

Description

technical field [0001] The invention relates to the related technical field of silo pumps, in particular to a silo pump for conveying cement materials. Background technique [0002] The warehouse pump, also known as the warehouse pump, is a relatively reliable dense-phase dynamic pressure pneumatic conveying device for conveying powdery materials under high pressure. It has the advantages of small area, flexible layout of conveying pipelines, high conveying efficiency, and can ensure that the conveyed materials are not damp and stained. At present, it is more and more used in the industrial field, and the conveying of cement materials can also be conveyed by warehouse pumps. . [0003] During the process of conveying cement materials through silo pumps, some problems often occur: [0004] 1. Under negative pressure conveying, when the material is directly dropped from the negative pressure feed pipe with a small diameter into the silo with a large volume, along with the in...

AI Technical Summary

Problems solved by technology

[0004] 1. Under negative pressure conveying, when the material is directly dropped from the negative pressure feed pipe with a small diameter to the silo with a large volume, it is easy to cause dust with the input of gas, and some materials Under the push of the gas, there will also be a floating situation. This part of the material is easy to adhere to the inner wall of the silo, which makes it difficult to collect the incoming material quickly and completely, resulting in waste. Failure to remove dust in time leads to the mixture of retained dust and cement materials. Mixed together, it is easy to affect the product quality of cement materials;

[0005] When positive pressure purges the air intake, the air intake position is usually provided with a sealing structure to prevent dust and gas from pouring in. When the compressed air is blown out, the sealing structure will be opened to open the air inlet, but the sealing structure When pushing away, part of the wind power will be wasted, and part of the conveying wind power will be wasted, and when the sealing structure is not fully ejected, it is easy to cause the trajectory of the compressed air to deviate from the predetermined trajectory
