Description

Pipe dust cleaning device

technical field

The invention mainly relates to a treatment device for dust accumulation in industrial dust-laden air flow pipes, in particular to a pipe dust cleaning device. the

Background technique

In industrial applications, pipelines are often used to convey dust-laden airflow to improve ventilation or to send away materials; however, in practical applications, often due to the small inclination angle of the pipeline, too long conveying pipeline or too slow airflow velocity, and the gravity of the dust itself The sedimentation effect causes some dust particles to accumulate in the pipeline; if the dust accumulation is not cleaned up in time, it will increase, resulting in a decrease in the ventilation area of the pipeline and an increase in resistance, which affects the flow of air flow; in severe cases, it will cause blockage and affect the upstream and downstream equipment. operation, resulting in an accident. After dust accumulation occurs, manual dust removal through openings is often used. The working environment is harsh, the links are cumbersome, and the workload is heavy; the dust that is drawn out needs to be transported and processed again; high. If it is dangerous gas or dust, it will cause gas or dust leakage, resulting in personal injury or even an accident. the

Contents of the invention

The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a pipeline dust cleaning device, which uses a pulse valve to inject high-pressure gas instantaneously, and then uses the high-pressure released gas to impact the deposited dust. The rapid movement of the gas drives the raised dust to move forward. The device has low energy consumption, is fast, convenient and easy to control. the

The present invention is achieved through the following technical solutions:

A pipe dust cleaning device, characterized in that: a plurality of blowing pipes are fixedly installed on the airflow pipe, one end of the blowing pipe extends out of the airflow pipe, and the protruding ends are respectively connected with the blowing branch pipes through high-pressure hoses , the other end of the injection branch pipe is connected to the pulse valve of the electromagnetic pulse valve, and the pulse valve is also connected to a gas supply branch pipe, and the gas supply branch pipe is connected to the gas supply pipeline, and the electromagnetic valve on the pulse valve is passed through the control cable connected to the controller. the

The pipe dust cleaning device is characterized in that: the blowing pipe is composed of a straight pipe, a 90° elbow, and a nozzle with a cut angle. The high-pressure hose of the hoop is connected with the injection branch pipe. the

The pipe dust cleaning device is characterized in that: the center line of the nozzle of the blowing pipe coincides with the center line of the air flow pipe. the

When the present invention is in use, multiple air supply branch pipes, pulse valves, injection branch pipes, high-pressure hoses with clamps, injection pipes, and control cables can be installed on the air supply pipeline according to the length of the airflow pipeline and the amount of dust accumulation. , Unified access to the controller to achieve segmental cleaning. At the same time, the type of compressed air can be selected according to the nature of the gas and dust in the airflow pipeline; generally, compressed air is used as the gas source; such as flammable and explosive gas or dust, inert gas can be used as the compressed gas source. the

The present invention adopts high-pressure hose connection to facilitate installation and disassembly, and the cutting angle of the nozzle can be designed according to the nature of the dust and the distance between the nozzle and the dust accumulation, so that the ejected airflow is aligned with the accumulated dust in the dust-laden airflow pipeline. On the gray side, the controller can automatically or manually control the start and stop of the solenoid valve according to the actual situation, and the connections are sealed with corresponding sealing materials. the

The advantages of the present invention are:

The present invention is simple in structure, easy to install and use, through the instantaneous expansion of compressed gas to impact dust accumulation, raise dust and take away dust, it can avoid dust affecting the normal operation of dust-containing gas in the pipeline; at the same time, it has less energy consumption, low cost and easy operation. Easy maintenance. the

Detailed ways

A pipe dust cleaning device, including a plurality of blowing pipes 6 fixedly installed on the air flow pipe 9 with dust 10, the blowing pipe 6 is composed of a straight pipe, a 90° elbow, and a nozzle with a cut angle. The end protrudes from the air flow pipe, and communicates with the injection branch pipe 4 through the high-pressure hose 5 with a clamp, and the other end of the injection branch pipe 4 communicates with the pulse valve 3-1 of the electromagnetic pulse valve 3, and the pulse valve 3 -1 is also communicated with an air supply branch pipe 2, and the electromagnetic valve 3-2 of the electromagnetic pulse valve 3 is connected to the controller 8 through the control cable 7; the

When there is dust accumulation 10 in the air flow pipe 9, the electromagnetic valve 32 on the electromagnetic pulse valve 3 can be activated by the controller 8, the pulse valve 3-1 is opened, and compressed gas is sprayed into the air flow pipe 9 in a very short time to compress The gas expands rapidly in the airflow pipe 9 while spraying to the dust accumulation 10, raises the dust accumulation 10 and rapidly increases the wind speed in the pipe 9, and drives the dust-laden airflow to move forward; thus, the dust accumulation 10 in the pipe is quickly removed Cleaning; in practical applications, multiple cleaning devices can be appropriately arranged according to the length of the pipeline 9 . the
