Description

Technical Field

[0001] This utility model relates to the technical field of pipeline unblocking, and in particular to a device for unblocking powder conveying pipelines. Background Technology

[0002] Powder materials need to be transported through conveying pipelines. However, the static electricity generated during the conveying process causes the powder to adhere to the inner wall of the conveying pipeline, which can easily clog the pipeline over a long period of time.

[0003] Existing pipe unblocking devices, such as the unblocking device for a powder conveying pipe disclosed in utility model patent application number 202320008577.1, mainly include a powder conveying pipe. Water pipes are respectively installed through the pipes on both sides of the inlet end of the powder conveying pipe, and butterfly valves are installed at the connection between the water pipes and the powder conveying pipe. A guide rail is installed on the front wall of the inside of the powder conveying pipe. In use, the push rod motor drives the annular scraper and annular cutter to reciprocate inside the pipe, thereby cleaning the remaining dust and sediment on the inner wall of the pipe, as well as some of the water remaining in the pipe, and pushing them all into the collection box.

[0004] However, most existing unblocking devices are directly connected to the pipeline, affecting the continuous smoothness of the pipeline's inner wall. The connection location is likely to cause blockage, and the location of each blockage in the pipeline may be very different. Most existing unblocking devices require the pre-determination of the blockage location, which is very troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a powder conveying pipeline unblocking device that not only facilitates pipeline inspection and eliminates the trouble of manually locating pipeline blockages, but also ensures the continuous smoothness of the pipeline inner wall by being externally mounted on the pipeline, thus avoiding the creation of new blockage points.

[0006] This utility model discloses a device for unclogging powder conveying pipelines, including a clamping mechanism, a moving mechanism, a detection mechanism, and three sets of vibration mechanisms. The moving mechanism is installed on the clamping mechanism and drives the device to move. The detection mechanism is installed on the clamping mechanism and detects the location of the pipeline blockage. The three sets of vibration mechanisms are installed on the clamping mechanism and drive the pipeline to vibrate and unblock. When the operator places the clamping mechanism on the pipeline, the moving mechanism works with the clamping mechanism to clamp the pipeline. The moving mechanism drives the clamping mechanism to move along the pipeline. The detection mechanism scans the pipeline to check the location of the blockage. When the blockage is found, the three sets of vibration mechanisms are activated to vibrate the pipeline, loosening the blockage material inside the pipeline.

[0007] Preferably, the clamping mechanism includes a positioning plate, a top plate, three sets of rollers and two sets of handles. The bottom end of the top plate is connected to the top end of the positioning plate. All three sets of rollers are rotatably mounted on the positioning plate, and all two sets of handles are mounted on the top plate. The operator operates the two sets of handles to place the device on the pipe, and the moving mechanism cooperates with the three sets of rollers to clamp the pipe.

[0008] Preferably, the moving mechanism includes four sets of hydraulic cylinders, a positioning slider, two sets of drive rollers, and a driver. All four sets of hydraulic cylinders are mounted on the top plate. The positioning plate has a groove. The positioning slider is slidably mounted in the groove of the positioning plate, and the top of the positioning slider is connected to the bottom of the two sets of hydraulic cylinders. The two sets of drive rollers are rotatably mounted on the positioning slider. The top of the driver is connected to the bottom of the other two sets of hydraulic cylinders, and the power output end of the driver is connected to the power input end of the two sets of drive rollers. The four sets of hydraulic cylinders push the positioning slider and the driver to descend, so that the two sets of drive rollers cooperate with the three sets of support rollers to clamp the pipe. The driver drives the two sets of drive rollers to rotate, thereby moving the device on the pipe.

[0009] Preferably, both the idler roller and the drive roller are drum-shaped structures; the drum-shaped structure is thinner in the middle and thicker at both ends, which can better fit the outer surface of the pipe and prevent the device from falling off the pipe.

[0010] Preferably, both the idler roller and the drive roller are covered with rubber pads; by applying rubber pads, the friction can be increased to ensure that the device moves on the pipeline and avoids scratching the pipeline surface, and the transmission of vibration can be slowed down to extend the service life of the device.

[0011] Preferably, the detection mechanism includes a controller, a sound wave transmitter, and an alarm. The controller is mounted on the top plate, the sound wave transmitter is mounted on the controller, and the alarm is mounted on the top plate. The controller controls the sound wave transmitter to emit sound waves to detect the pipeline. When a blockage is detected in the pipeline, the controller triggers the alarm and then controls the drive to stop moving.

[0012] Preferably, the vibration mechanism includes a vibrator, multiple sets of vibrating hammers, and multiple sets of elastic pads. The vibrator is mounted on the top plate, and the power output end of the vibrator is connected to the power input end of the multiple sets of vibrating hammers. The multiple sets of elastic pads are respectively mounted on the multiple sets of vibrating hammers. The controller controls the start of the vibrator, which drives the multiple sets of vibrating hammers to move back and forth to strike the pipeline. By setting multiple sets of elastic pads, the hard hammers are prevented from directly impacting the pipeline, thus preventing damage to the paint and anti-corrosion layer on the outer wall of the pipeline, and noise can also be reduced.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff places the clamping mechanism on the pipe, the moving mechanism cooperates with the clamping mechanism to clamp the pipe, the moving mechanism drives the clamping mechanism to move along the pipe, the detection mechanism scans the pipe to check the blockage location, and when the blockage location is found, the three sets of vibration mechanisms are activated to drive the pipe to vibrate, so that the blockage material in the pipe is loosened.
