Description

A dust-proof dry powder material collection device

technical field

The utility model belongs to the field of material collection equipment, in particular to a dust-proof dry powder material collection device.

Background technique

When using a container with a highly airtight outer wall to collect and transport dry powder materials, if the container mouth is sealed with the dry powder material discharge mechanism, the air pressure inside the container will gradually increase due to the entry of dry powder materials during discharge, and the subsequent The dry powder material cannot enter the container smoothly due to the increase of the air pressure inside the container; and when the container mouth is not sealed with the dry powder material discharge mechanism, the dust generated when the dry powder material falls into the container will scatter from the container mouth and pollute surrounding environment, and even lead to safety accidents.

Utility model content

Based on the above problems in the prior art, the utility model provides a dust-proof dry powder material collection device, including a ton bag, a blanking pipe, a blanking dust collection sleeve, a dust collection pipe, and a dust collector. The sleeve includes an inner tube and an outer tube. The outer tube of the blanking dust collection sleeve is set outside the inner tube. There is a gap between the outer wall of the inner tube of the blanking dust collection sleeve and the inner wall of the outer tube, and the upper end of the gap is closed. The upper end of the inner tube of the blanking dust collection sleeve is sealed and connected with the blanking tube through a telescopic tube, and the upper opening of the ton bag is sealed and connected with the lower end of the outer tube of the blanking dust collection sleeve through a tightening belt. The upper end of the outer pipe of the material dust collection sleeve is connected to the outer side and communicates with the gap between the inner pipe and the outer pipe. The other end of the dust collection pipe is connected to the dust collector. The dust collector passes the air on the upper part of the big bag by creating a negative pressure environment. The gap between the inner tube and the outer tube of the blanking dust collection sleeve is sucked into the dust collector, thereby reducing dust and speeding up blanking. The dust-proof dry powder material collecting device provided by the utility model has the advantages of reducing dust, fast feeding speed, simple structure and low cost.

The utility model achieves the goal through the following detailed technical solutions:

A dust-proof dry powder material collection device, including a ton bag, a blanking pipe, a blanking dust collection sleeve, a dust collection pipe, and a dust collector. The blanking dust collection sleeve includes an inner tube and an outer tube. The outer tube of the material dust collection sleeve is set outside the inner tube. There is a gap between the outer wall of the inner tube of the falling material dust collection sleeve and the inner wall of the outer tube, and the upper end of the gap is closed. The material pipe is sealed and connected by a telescopic pipe, the upper opening of the ton bag is sealed and connected with the lower end of the outer pipe of the blanking dust collection sleeve through a tightening belt, and the dust collection pipe is connected and communicated with the outer side of the upper end of the outer pipe of the blanking dust collection sleeve The gap between the inner pipe and the outer pipe, the other end of the dust collection pipe is connected to the dust collector, and the dust collector passes the air on the upper part of the big bag through the gap between the inner pipe and the outer pipe of the blanking dust collection sleeve by creating a negative pressure environment The gap is sucked into the dust collector, so that the inside of the big bag is in a negative pressure state;

When collecting dry powder materials, the dry powder materials fall through the drop pipe and the inner tube of the dust collection sleeve into the ton bag. Due to the negative pressure environment in the dust collector, the inside of the ton bag connected to the dust collector is also in a negative pressure state. Subsequent dry powder materials can smoothly fall into the big bag; in addition, due to the negative pressure environment in the dust collector, the dust caused by the dry powder material falling into the big bag passes through the gap between the inner tube and the outer tube of the blanking dust collection sleeve. The dust collection pipe is sucked into the dust collector, which effectively prevents the dust from escaping.

It should be noted that the above-mentioned dry powder material collection device is not only suitable for the collection of dry powder materials in big bags, but also suitable for other collection containers similar to big bags.

Wherein, the dust collector includes a dust removal chamber, a negative pressure chamber, multiple sets of dust removal cloth bags, multiple sets of compressed air nozzles, an exhaust fan, and a dust collection bag. The dust collection pipe communicates with the dust removal chamber, and the dust removal chamber It is arranged under the negative pressure chamber, the lower end of the dust removal chamber is funnel-shaped and provided with a dust collection leak, the opening of the dust collection bag is connected to the bottom of the dust collection leak through a tightening belt, and the dust removal chamber is connected to the negative pressure chamber. There are multiple groups of decompression air holes connecting the two chambers. The dust removal bag is set in the dust removal chamber and the bag mouth is connected to the decompression air hole on one side of the dust removal chamber. The compressed air nozzle is located in the negative pressure chamber. In the chamber and located above the decompression air hole, the air jet direction is facing the decompression air hole, and the exhaust fan is connected to the inside of the negative pressure chamber to discharge the air inside the negative pressure chamber to the outside of the negative pressure chamber;

Because the exhaust fan discharges the air inside the negative pressure chamber to the outside of the negative pressure chamber, a negative pressure is formed in the negative pressure chamber, and the air in the dust removal chamber enters the negative pressure chamber through the decompression hole; After the dust pipe enters the dust removal chamber, it is filtered by the dust removal bag, enters the negative pressure chamber through the decompression hole, and then is discharged to the outside of the dust collector through the exhaust fan; when there is too much dust on the dust removal bag, the compressed air nozzle can be opened to use the compressed air The air blows off the agglomerated dust on the dust removal bag, and collects it into the dust collection bag through the funnel-shaped lower end of the dust removal chamber to complete the cleaning of the dust collector and ensure the later dust removal effect. When cleaning the dust accumulation, the exhaust fan can be turned off.

Wherein, the dust collection pipeline is provided with a check valve, which can be closed during dust cleaning to prevent the dust from flowing back and escaping; The observation window is convenient for regular dust cleaning.

The utility model adopts the above-mentioned technical scheme and has the advantages of reducing dust, fast feeding speed, simple structure and low cost.
