Description

Technical Field

[0001] The invention relates to the technical field of coal pipeline obstacle removal, and in particular to an anti-blocking and obstacle removal device based on a coal pipeline. Background Art

[0002] Coal pipeline is a new mode of transportation, mainly used in industrial transportation. The pipeline coal transportation system consists of three main parts: pulping plant, pipeline and pumping station, and terminal dehydration plant, as well as related supporting facilities such as water supply, power supply, communication and automatic control. When using coal pipeline to transport coal or other solid minerals, liquid is required as the medium, that is, solid and liquid are added to make slurry, and then transported by pipeline.

[0003] Even though liquid has been used to enhance the fluidity of coal during transportation, since the volume of solid coal is not fixed, there will still be problems with coal pipeline blockage during transportation, seriously affecting the transportation efficiency of the coal pipeline. Most of the coal pipeline clearing devices in the prior art have poor effects and it is difficult to clear larger solids. Therefore, there is an urgent need for a device that can clear obstacles in solid transportation pipelines. Summary of the invention

[0004] In order to solve the above problem, that is, the problem that the existing dredging devices have poor dredging effect on solid pipelines, the present invention proposes an anti-blocking and obstacle-clearing device based on coal transportation pipelines, which includes a driving device, and a rotating head is installed at the output end of the driving device. The driving device is used to drive the rotating head to rotate, and a conical head is installed at the end of the rotating head away from the driving device. No less than two mounting plates are coaxially connected to the side wall of the rotating head, and the diameter of the mounting plates is arranged to increase successively from left to right. The side wall of the conical head is evenly installed with three crushing knives along its circumference, and the side wall of the mounting plate is also evenly installed with three crushing knives along its circumference.

[0005] The present invention is further configured as follows: a water inlet is provided at one end of the rotating head close to the driving device for connecting to a high-pressure water delivery device, and three axial water spray outlets are evenly provided on the conical head, and the axial water spray outlets are connected to the water inlet.

[0006] The present invention is further configured as follows: three lateral water spray outlets are also provided on the rotating head between the conical head and the mounting plate, and three lateral water spray outlets are also provided on the rotating head between any two adjacent mounting plates, and the lateral water spray outlets are connected to the water inlet.

[0007] The beneficial effects of the present invention are:

[0008] 1. By gradually increasing the diameter of the mounting plate, the device can be fed linearly, and by installing a crushing knife on the mounting plate, the coal blocks can be crushed and cut, and the coal pipeline can be cleared to avoid blockage in the coal pipeline.

[0009] 2. By setting up the axial water spray port, the conveyed material in front of the device can be further flushed to wash away the blocked powder or small pieces of material, while the lateral water spray port can spray water in the direction perpendicular to the axis, further expanding the obstacle clearance space around the device and achieving better obstacle clearance effect.

[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] The present invention proposes an anti-blocking and obstacle-clearing device based on a coal conveying pipeline, comprising a driving device 1, wherein the driving device 1 selects a driving motor, and a rotating head 2 is fixedly connected to the output end of the driving device 1, and the driving device 1 is used to drive the rotating head 2 to rotate, and a conical head 3 is welded to the end of the rotating head 2 away from the driving device 1. Two mounting plates 4 are welded to the side wall of the rotating head 2, and the two mounting plates 4 are arranged equidistantly, and the diameters of the two mounting plates 4 are set differently, and the diameter of the mounting plate 4 located on the left side is smaller than the diameter of the mounting plate 4 located on the right side, that is, the diameters of the mounting plates 4 are set to increase from left to right.

[0016] Three crushing knives 5 are evenly welded on the side wall of the conical head 3 along its circumference, and crushing knives 5 are also evenly welded on the side wall of the mounting plate 4 along its circumference. Due to the different diameters of the mounting plates 4, the cutting diameters after the crushing knives 5 are welded are also different.

[0017] A water inlet 21 is provided at one end of the rotating head 2 close to the driving device 1. The water inlet 21 is used to connect to the high-pressure water delivery device. A connecting channel is provided inside the rotating head 2 for connecting to the water inlet 21. Three axial water spray ports 31 are provided on the conical head 3. The three axial water spray ports 31 are evenly arranged along the axis of the conical head 3. The axial water spray ports 31 are connected to the water inlet 21 through the connecting channel, and then the high-pressure water delivery device is connected to the axial water spray ports 31 through the water inlet 21, so as to achieve the purpose of spraying water to the front end of the conical head 3, and further achieve the purpose of clearing the powder or small-volume materials in front of the conical head 3.

[0018] Three lateral water spray outlets 22 are also provided on the rotating head 2 between the conical head 3 and the mounting plate 4, and three lateral water spray outlets 22 are also provided on the rotating head 2 between any two adjacent mounting plates 4. The lateral water spray outlets 22 can expand the obstacle clearance space around the device during feeding and crushing, thereby further improving the obstacle clearance effect.

[0019] It should be noted that the crushing knife 5 needs to be installed at a certain angle, that is, when the rotating head 2 is rotated, under the action of the crushing knife 5, the rotating head 2 will feed forward, and the reaction force generated by the water sprayed from the axial water nozzle 31 is much smaller than the feed force, and thus the water sprayed from the axial water nozzle 31 will not affect the feed of the rotating head 2.

[0020] In summary, the present invention can make the device linearly feed by gradually increasing the diameter of the mounting plate 4, and installing the crushing knife 5 on the mounting plate 4 can achieve the crushing and cutting effect on the coal block, and further achieve the obstacle clearing effect on the coal conveying pipeline to avoid blockage in the coal conveying pipeline. By setting the axial water spray port 31, the conveying material in front of the device can be further flushed to flush out the blocked powder or small pieces of material, and the lateral water spray port 22 can spray water in a direction perpendicular to the axis, further expanding the obstacle clearing space around the device, so that the obstacle clearing effect is better.
