Description

Technical Field

[0001] This utility model relates to the field of material conveying, and in particular to a material conveying pipeline anti-blocking device. Background Technology

[0002] As an indispensable component of material conveying pipelines, bends in pipes are prone to causing flow obstruction when materials pass through them due to the change in pipeline direction. At bends, materials are subjected to a combination of forces, including gravity, centrifugal force, and friction with the pipe wall, significantly reducing their flow velocity. When the material flow rate is large or the material itself has poor flowability, this reduction in velocity can lead to gradual accumulation of material within the bend, eventually causing localized blockages and severely impacting the continuity and stability of material conveying.

[0003] Currently, while some solutions exist for addressing blockages at bends in material conveying pipelines, most have limitations. For example, some methods can only clear blockages after they occur, failing to prevent them in advance, leading to frequent shutdowns due to blockages during production. Other methods, while improving material flow to some extent, are ineffective at cleaning deposits on the inner walls of bends, failing to fundamentally solve the blockage problem. Utility Model Content

[0004] The purpose of this invention is to provide a material conveying pipeline anti-blockage device to effectively prevent and solve the problem of blockage at the bend of the material conveying pipeline.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a material conveying pipeline anti-blocking device, the material conveying pipeline anti-blocking device comprising:

[0006] A ring-shaped unblocking pipe, wherein the ring-shaped unblocking pipe is arranged around the front end of the bend;

[0007] Multiple L-shaped unblocking nozzles, one end of each L-shaped unblocking nozzle is connected to the annular unblocking pipe, and the other end of each L-shaped unblocking nozzle is inserted into the inside of the bend pipe and is in close contact with the inner wall of the bend pipe. The air jet direction of each L-shaped unblocking nozzle is along the material flow direction.

[0008] An air pump, the output end of which is connected to the annular drain pipe via a pipeline.

[0009] In one embodiment, the device further includes an electronic pressure gauge and a PLC control module. The electronic pressure gauge is located at the front end of the bend, and the PLC control module is electrically connected to the electronic pressure gauge and the air pump.

[0010] In one embodiment, the L-shaped unblocking nozzles are evenly arranged around the bend.

[0011] In one embodiment, the L-shaped unclogging nozzle is embedded in the bend, and the nozzle's spray end is flush with the inner wall of the bend.

[0012] In one embodiment, the air pump is fixed to the bend.

[0013] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages:

[0014] The anti-clogging device for material conveying pipelines provided in this embodiment of the invention features an annular unblocking pipe and multiple L-shaped unblocking nozzles at the front end of a bend. One end of each L-shaped nozzle is connected to the annular pipe, while the other end penetrates the bend and fits tightly against its inner wall. The air jet direction is along the material flow direction. When the air pump operates, high-pressure gas is pumped into the annular pipe and then flows through it to the L-shaped nozzles. The high-pressure gas ejected from the L-shaped nozzles exerts a continuous air pressure impact on the material within the bend along the material flow direction. This impact effectively increases the flow velocity of the material within the bend, preventing material accumulation due to reduced velocity. This prevents material blockage at its source, ensuring the continuity and stability of material conveying, reducing production interruptions caused by blockages, and improving production efficiency.

[0015] Furthermore, because the other end of the L-shaped cleaning nozzle is in close contact with the inner wall of the bend, and the air jet direction is along the material flow direction, the high-pressure gas ejected from the nozzle not only propels the material but also directly impacts the inner wall of the bend. This direct air pressure impact effectively cleans the deposits on the inner wall of the bend, preventing them from accumulating and thickening, and avoiding the problem of excessive deposits reducing the effective flow area of ​​the bend and exacerbating the risk of blockage. Compared with traditional cleaning methods, the device of this invention can clean the inner wall of the bend in real time during material conveying, without the need for machine shutdown for special cleaning operations, greatly reducing cleaning costs and labor intensity, and extending the service life of the bend.

[0026] Please see Figures 1 to 3This application provides an anti-clogging device for a material conveying pipeline, including an annular unblocking pipe 1, multiple L-shaped unblocking nozzles 2, and an air pump 3. The annular unblocking pipe 1 is arranged around the front end 6 of a bend. One end of each L-shaped unblocking nozzle 2 is connected to the annular unblocking pipe 1, and the other end of each L-shaped unblocking nozzle 2 extends into the bend, with the other end pressed against the inner wall of the bend. The air jet direction of the L-shaped unblocking nozzle 2 is along the material flow direction. The output end of the air pump 3 is connected to the annular unblocking pipe 1 via a pipe.

[0027] The anti-blocking device for the material conveying pipeline provided by this utility model is installed at the front end of the bend of the material conveying pipeline. When the air pump 3 is working, it pumps high-pressure gas into the annular unblocking pipe 1, and the gas flows through the annular unblocking pipe 1 to the L-shaped unblocking nozzle 2. The high-pressure gas sprayed from the L-shaped unblocking nozzle 2 flows along the material flow direction ( Figure 1-2 The material flows from right to left, which can generate air pressure impact force on the material in the bend, increase the material flow speed, and clean the deposits on the inner wall of the bend, avoiding long-term accumulation and sedimentation that could cause blockage in the bend.

[0028] In one embodiment, the system also includes an electronic pressure gauge 4 and a PLC control module 5. The electronic pressure gauge 4 is located at the front end 6 of the bend, and the PLC control module 5 is electrically connected to the electronic pressure gauge 4 and the air pump 3. When material accumulates in the bend and there is a tendency to blockage, the pressure value inside the bend increases. At this time, the electronic pressure gauge 4 transmits the pressure value to the PLC control module 5. The PLC control module 5 controls the output power of the air pump 3 according to the pressure value, so that when material accumulates in the bend and there is a tendency to blockage, the PLC control module 5 controls the output power of the air pump 3 to increase, thereby increasing the flow rate and volume of the high-pressure gas sprayed from the L-shaped unblocking nozzle 2, thereby increasing the impact force of the high-pressure gas on the material, improving the unblocking effect of the high-pressure gas, and avoiding blockage.

[0029] The control circuit and control principle of the PLC control module 5 controlling the output power of the air pump 3 according to the pressure value are common knowledge in the field. Both the PLC control module 5 and the electronic pressure gauge 4 are existing devices, and no structural improvements have been made to them. Therefore, the specific structures of the PLC control module 5 and the electronic pressure gauge 4 are omitted.

[0030] In one embodiment, L-shaped cleaning nozzles 2 are evenly arranged around the bend. By evenly arranging the L-shaped cleaning nozzles around the bend, the high-pressure gas ejected from each nozzle can be evenly distributed inside the bend. This evenly distributed air pressure impact force can more comprehensively push the material inside the bend, avoiding the situation where material easily accumulates in some areas due to uneven gas action, thus improving the cleaning and anti-clogging effect.

[0031] In one embodiment, the L-shaped cleaning nozzle 2 is embedded in the bend, with the nozzle's discharge end flush with the inner wall of the bend. By aligning the nozzle's discharge end with the inner wall of the bend, the nozzle is prevented from protruding from the bend, thus reducing the obstruction of the nozzle's own flow of material within the bend.

[0032] In one embodiment, the air pump 3 is fixed to the bend. When the air pump 3 is working, the vibration energy it generates acts on the bend, which plays a certain auxiliary cleaning role, helping to loosen some loose deposits on the inner wall of the bend, making them easier to be blown away by high-pressure gas, thereby further improving the unblocking and anti-clogging effect and ensuring the efficiency and stability of material transportation in the bend.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
