Description

Technical Field

[0001] This utility model relates to the field of hopper unblocking technology, and in particular to a jet-type unblocking and anti-blocking device. Background Technology

[0002] In the industrial material conveying sector (such as coal, ore, and grain), the frequent problem of hopper and pipeline blockage has long been a major concern. Materials, due to moisture, viscosity, or electrostatic forces, easily form bridging or arching, and the deposited layer on the pipe wall is a primary cause of blockage. Traditional unblocking methods, such as manual tapping and vibrators, have significant shortcomings—they are incomplete and leave blind spots, leading to frequent shutdowns that severely disrupt production continuity. Furthermore, the mechanical impact of vibrators or uncontrolled high-pressure air blowing can easily cause loosening of equipment connections and weld cracking, exacerbating pipe wall corrosion and wear, and significantly increasing maintenance costs and safety hazards.

The first air blowing port is embedded obliquely downward in the outer wall of the hopper pipe 2.

[0023] The second air blowing assembly 9 includes a second shut-off valve 91, a second control valve 92, a second hose 93, and a second air blowing port 94; one end of the second shut-off valve 91 is connected to the first pipeline 7, and the other end is connected to the second control valve 92; the other end of the second control valve 92 is connected to the second air blowing port 94 through the second hose 93; the second air blowing port 94 is embedded in the outer wall of the hopper pipe 2. The second air inlet 94 includes a first substrate 941 and a second substrate 942. The first substrate 941 is embedded in the outer wall of the hopper tube 2. One side of the first substrate 941 is connected to the second flexible tube 93, and the other side is connected to the second substrate 942. A through hole 943 is provided at one end of the first substrate 941. A groove 944 is provided on the side of the second substrate 942 connected to the first substrate 941.

[0024] The pipe wall cleaning device includes a rotating assembly 41, a scraper 42, a drive motor, and a transmission assembly.

[0026] The hopper pipe 2 can be equipped with a single-layer jet-type unblocking mechanism or a multi-layer jet-type unblocking mechanism. Multi-layer unblocking provides comprehensive unblocking, while single-layer unblocking provides targeted unblocking. The number of layers is not limited. Figure 1-2 As shown, Figure 1 and Figure 2 A multi-layered jet-type unblocking mechanism is installed. When the unblocking and anti-clogging device is working, the hopper 1 rotates under the action of the rotating connecting assembly, reducing material blockage and bridging within the hopper 1. Pressurized gas enters the jet-type unblocking mechanism through the second pipeline 3, and then enters the hopper tube 2 through the first pipeline 7, the first air blowing assembly 8, and the second air blowing assembly 9. Both the first control valve and the second control valve 92 can be electronic pulse valves. The jet-type unblocking mechanism blows air into the hopper tube 2, cutting the material inside into multiple pieces, thus achieving the unblocking effect. Because the first air blowing port is angled downwards on the wall of the hopper tube 2, it delivers gas angled downwards into the hopper tube 2. The second air blowing port 94, due to its groove... The guiding function of 944 delivers downward fan-shaped gas along the inner wall of the hopper pipe 2, expanding the jetting area and forming an air film between the coal and the pipe wall in the hopper pipe 2, which can blow away the blocked material over a wider area. When the jet-type unblocking mechanism is working, under the action of the control system, the first control valve and the second control valve 92 control whether the first air outlet and the second air outlet 94 blow air into the hopper pipe 2. After blowing air into the hopper pipe 2 for a period of time, the blowing stops for a period of time, and then the blowing and stopping actions are repeated cyclically. At the same time, the drive motor in the pipe wall cleaning mechanism 4 drives the scraper 42 to perform scraping action along the inner wall of the hopper pipe 2 through the transmission component and the rotating component 41.

[0027] Therefore, the jet-type anti-clogging and unblocking device of this utility model can solve the problems of easy blockage and incomplete blockage removal in the existing industrial material conveying process.
