Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, and more specifically, to a high-pressure pneumatic cleaning device. Background Technology

[0002] During production, due to various factors such as processes, materials need to be mixed and stored in proportions. Various structural types of material silos are typically used. Material silos frequently experience blockages, material adhesion, and arching due to various reasons, severely impacting production and process requirements. First, we can consider materials as fluid substances; under normal circumstances, they are fluid. However, when materials are moist, have increased moisture content, or are too fine, their viscosity and friction increase, reducing fluidity. When a large amount of material passes through the discharge port simultaneously, it easily becomes blocked, causing material flow interruption. Furthermore, with reduced material flow, the weight of the material in the silo further compresses it, causing a small amount of material to adhere to the silo wall. Over time, this adhesion thickens, forming a buildup. Generally, during material discharge from the silo, the flow rate is faster at the center and slower on the sides. Therefore, during discharge, the material in the center compresses the material on the sides, creating a thick layer of adhesion that is very difficult to handle later, sometimes requiring equipment shutdown and manual intervention. This situation significantly impacts the company's operations, economy, and production safety.

[0003] Currently, manual cleaning is the most common method for cleaning silos. Manual cleaning requires the use of appropriate tools such as pneumatic blowers. The cleaning cycle is long, and the effectiveness depends on the worker's skill level. Moreover, some silos are not suitable for manual cleaning, which can easily lead to personal safety accidents.

[0005] The purpose of this application is to provide a high-pressure pneumatic cleaning device to solve the problems of long cleaning cycles, inconsistent cleaning results depending on the skill level, and the risk of personal safety accidents in the prior art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides a high-pressure pneumatic cleaning device for cleaning a silo, comprising a high-pressure gas generating assembly, a first spray gun, a second spray gun, and a knocking vibration assembly; the high-pressure gas generating assembly is used to compress atmospheric pressure gas into high-pressure gas; the first spray gun is connected to the high-pressure gas generating assembly and has a nozzle parallel to the radial direction of the silo; the second spray gun is connected to the high-pressure gas generating assembly and has an arc-shaped nozzle, the outer edge of which is in contact with the inner wall of the silo, and the gas ejection direction of the arc-shaped nozzle is parallel to the inner wall of the silo; the knocking vibration assembly is disposed on the outer wall of the silo and is used to knock the silo to cause the silo to vibrate.

[0009] Preferably, the high-pressure gas generating assembly includes an air compressor, a first air source, a first pipeline, a second pipeline, and a first valve. The first air source is connected to the air inlet of the air compressor through the first pipeline, and the air outlet of the air compressor is connected to the first spray gun and the second spray gun through the second pipeline. The first valve is located on the first pipeline.

[0010] Preferably, the high-pressure gas generating assembly further includes a second gas source, a third pipeline, and a second valve. The second gas source is connected to the air inlet of the air compressor through the third pipeline, and the second valve is located on the third pipeline.

[0011] Preferably, the high-pressure gas generating assembly further includes a gas heating box, which is disposed on the first pipeline.

[0012] Preferably, the impact vibration assembly includes a servo motor, a swing arm, and an impact block; the servo motor is connected to the outer wall of the hopper, one end of the swing arm is connected to the output shaft of the servo motor, and the other end of the swing arm is connected to the impact block.

[0013] Preferably, the striking block has a striking surface that conforms to the shape of the outer wall of the hopper.

[0014] Preferably, the striking surface is provided with a buffer layer.

[0015] Preferably, there are multiple first spray guns, which are arranged at intervals along the circumference of the hopper.

[0016] Preferably, there are multiple second spray guns, which are arranged at intervals along the circumference of the hopper.

[0018] (III) Beneficial Effects

[0019] The above-mentioned technical solution of this utility model has at least the following advantages:

[0020] The high-pressure gas generating component generates high-pressure gas which is ejected from the first spray gun. The first spray gun has a nozzle parallel to the radial direction of the hopper. The high-pressure gas ejected from the first spray gun acts on the blockage inside the hopper, which can solve the blockage problem caused by solidification and arching. The high-pressure gas generating component also generates high-pressure gas which is ejected from the second spray gun. Because the second spray gun has an arc-shaped nozzle, the outer edge of which fits against the inner wall of the hopper, and the gas ejection direction of the arc-shaped nozzle is parallel to the inner wall of the hopper, the second spray gun can spray arc-shaped air blades. The arc-shaped air blades can increase the clearing area and more effectively remove the hardened blockages that adhere to the inner wall of the hopper. At the same time, it can form a gas membrane that conforms to the shape of the inner wall of the hopper. For more moist blockages, the arc-shaped air blades separate the blockages from the inner wall of the hopper, preventing the blockages from adhering to the inner wall of the hopper again. After the arc-shaped air blade cuts the hardened blockage from the inner wall of the silo, the vibration component strikes the silo, causing it to vibrate and making it easier for the blockage to detach from the inner wall and fall down. This invention can be directly installed on the silo and, through connection to the control component, can achieve automated cleaning of the silo, avoiding manual cleaning. Compared to manual cleaning, it is more efficient and safer. Attached Figure Description

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model embodiment provides a high-pressure pneumatic cleaning device for cleaning a silo 100, including a high-pressure gas generating component 1, a first spray gun 2, a second spray gun 3, and a knocking vibration component 4; the high-pressure gas generating component 1 is used to compress atmospheric pressure gas into high-pressure gas; the first spray gun 2 is connected to the high-pressure gas generating component 1, and the first spray gun 2 has a nozzle parallel to the radial direction of the silo 100; the second spray gun 3 is connected to the high-pressure gas generating component 1, and the second spray gun 3 has an arc-shaped nozzle 31, the outer edge of the arc-shaped nozzle 31 is in contact with the inner wall of the silo 100, and the gas ejection direction of the arc-shaped nozzle 31 is parallel to the inner wall of the silo 100; the knocking vibration component 4 is disposed on the outer wall of the silo 100 and is used to knock the silo 100 to make the silo 100 vibrate.

[0033] High-pressure gas generating component 1 generates high-pressure gas which is ejected from the first spray gun 2. The first spray gun 2 has a nozzle parallel to the radial direction of the hopper. The high-pressure gas ejected from the first spray gun 2 acts on the blockage inside the hopper 100, which can solve the blockage problem caused by solidification and arching. High-pressure gas generating component 1 generates high-pressure gas which is ejected from the second spray gun 3. Since the second spray gun 3 has an arc-shaped nozzle 31, the outer edge of the arc-shaped nozzle 31 is in contact with the inner wall of the hopper 100, and the gas ejection direction of the arc-shaped nozzle 31 is parallel to the inner wall of the hopper 100, the second spray gun 3 can eject arc-shaped air blades. The arc-shaped air blades can increase the clearing area and more effectively remove the hardened blockages that adhere to the inner wall of the hopper 100. At the same time, it can form a gas membrane with the same shape as the inner wall of the hopper 100. For more moist blockages, the arc-shaped air blades separate the blockages from the inner wall of the hopper 100, preventing the blockages from adhering to the inner wall of the hopper again. After the arc-shaped air blade cuts the hardened blockage from the inner wall of the hopper 100, the striking vibration component 4 strikes the hopper 100 to make the hopper 100 vibrate, making it easier for the blockage to detach from the inner wall of the hopper 100 and fall down.

[0034] As one of the optional implementations of this embodiment, the high-pressure pneumatic cleaning device also includes a control component. The control component is electrically connected to the high-pressure gas generating component 1. The control component has a built-in control program, which can automatically control the high-pressure gas generating component 1 to start, thereby realizing the automated cleaning of the silo.

[0035] As one of the optional implementations of this embodiment, the high-pressure gas generating assembly 1 includes an air compressor 11, a first gas source 12, a first pipe 13, a second pipe 14 and a first valve 15. The first gas source 12 is connected to the air inlet of the air compressor 11 through the first pipe 13, and the air outlet of the air compressor 11 is connected to the first spray gun 2 and the second spray gun 3 through the second pipe 14. The first valve 15 is provided on the first pipe 13.

[0036] As one optional implementation of this embodiment, the high-pressure gas generating assembly 1 further includes a second gas source 16, a third pipeline 17, and a second valve 18. The second gas source 16 is connected to the air inlet of the air compressor through the third pipeline 17, and the second valve 18 is disposed on the third pipeline 17. When the first valve 15 is opened and the second valve 18 is closed, the second pipeline 14 outputs the first gas source 12; when the first valve 15 is closed and the second valve 18 is opened, the second pipeline 14 outputs the second gas source 16, thereby realizing the switching output of different gas sources.

[0037] The first gas source 12 and the second gas source 16 are of different types. In this embodiment, the first gas source 12 is preferably air, which is readily available, low in cost, and suitable for use in general scenarios. The second gas source 16 can be a single-element gas, such as nitrogen or carbon dioxide, or it can be a non-flammable or non-combustible gas. The second gas source 16 can be used as a fire-fighting gas. For example, if a fire occurs inside the silo, the first gas source 12, which uses air, is not suitable, and the second gas source 16 can be switched to continue working or to extinguish the fire. Alternatively, the first gas source 12 and the second gas source 16 can have different pressures to meet the needs of different silo blockage faults. For example, for minor material accumulation, low-compressed air can be used. For more severe blockages, a larger flow rate of medium- or high-pressure airflow is required for unblocking.

[0038] As one optional implementation of this embodiment, the high-pressure gas generating assembly 1 further includes a gas heating box 19, which is disposed on the first pipeline 13. The gas heating box 19 can heat the first gas source 12 to form dry and anhydrous compressed gas, which is used for particulate materials where the process requires reduced oxidation reaction and electrostatic sparks; or the gas heating box 19 can heat the first gas source 12 to a preset temperature to adapt to special working conditions where the material in the silo needs to avoid moisture condensation and freezing.

[0039] In one optional implementation of this embodiment, the impact vibration assembly 4 includes a servo motor 41, a swing arm 42, and an impact block 43. The servo motor 41 is connected to the outer wall of the hopper 100, one end of the swing arm 42 is connected to the output shaft of the servo motor 41, and the other end of the swing arm 42 is connected to the impact block 43. The servo motor 41 can drive the swing arm 42 to swing, thereby causing the impact block 43 to strike the hopper.

[0040] As one optional implementation of this embodiment, the striking block 43 has a striking surface 431 that conforms to the shape of the outer wall of the hopper 100. For example, when the outer wall of the hopper is circular, the striking surface 431 is circular and its curvature is consistent with that of the outer wall of the hopper, so as to achieve better contact and striking and expand the vibration source.

[0041] As one optional implementation of this embodiment, a buffer layer is provided on the striking surface 431. The buffer layer can prevent hard contact between the striking block 43 and the hopper from damaging the hopper.

[0042] As one optional implementation of this embodiment, there are multiple first spray guns 2, which are arranged at intervals along the circumference of the hopper 100. This is to clear blockages at various locations in the hopper and improve work efficiency. Furthermore, the multiple first spray guns 2 are connected in parallel to a first main pipe, which is connected to a second pipe 14. A one-way valve is provided on the first main pipe.

[0043] As one optional implementation of this embodiment, there are multiple second spray guns 3, which are arranged at intervals along the circumference of the hopper 100. This is to clear blockages at various locations in the hopper and improve work efficiency. Furthermore, the multiple second spray guns 3 are connected in parallel to a second main pipe, which is connected to a second pipe 14 and is equipped with a one-way valve.

[0044] As one of the optional implementations of this embodiment, the striking vibration component 4 is disposed below the second spray gun 3.

[0045] The above description is only a preferred embodiment of the present utility model and is 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.
