Description

Technical Field

[0001] This utility model relates to the field of unblocking devices, and in particular to an unblocking device with a single high and low pressure air source. Background Technology

[0002] In industries such as chemical, building materials, metallurgy, power plants, and steel mills, materials in various raw material, fuel, cement, grain, and mixed material silos may arch, bridge, or clump due to the transition and contraction sections of the silo body, pressure, material moisture, or high air humidity.

[0003] This results in a smaller silo volume and lower silo utilization efficiency, which in turn causes malfunctions such as feeder interruption and coal interruption, affecting normal production and even causing safety accidents. Therefore, it is necessary to clean the silo regularly. Existing silo cleaning methods mainly rely on manual cleaning, which is time-consuming, labor-intensive, and poses safety hazards. Other cleaning methods, such as air cannons, vibrators, and loosening machines, have low cleaning efficiency, high wear and tear, and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high wear and high maintenance costs in the existing methods of cleaning material silos, and to provide a high and low pressure single air source unblocking device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high- and low-pressure single-source unblocking device, comprising a silo body, a low-pressure air circuit mechanism fixedly connected to the outer surface of the silo body, the low-pressure air circuit mechanism comprising a low-pressure air nozzle, a low-pressure air pipe fixedly connected to the outer surface of the low-pressure air nozzle, a second solenoid valve fixedly connected to the outer surface of the low-pressure air pipe, a first low-pressure air tank fixedly connected to the outer surface of the second solenoid valve, a low-pressure air valve fixedly connected to the outer surface of the first low-pressure air tank, a low-pressure air inlet pipe fixedly connected to the inner wall of the low-pressure air valve, a second low-pressure air tank fixedly connected to the outer surface of the low-pressure air inlet pipe, and a connecting mechanism fixedly connected to the outer surface of the low-pressure air inlet pipe, the connecting mechanism comprising a one-way valve.

[0006] In a preferred embodiment, a pressure reducing valve is fixedly connected to the outer surface of the one-way valve, a first connecting pipe is fixedly connected to the outer surface of the pressure reducing valve, a first solenoid valve is fixedly connected to the outer surface of the first connecting pipe, and a high-pressure air circuit mechanism is fixedly connected to the inner wall of the first solenoid valve. The high-pressure air circuit mechanism includes a high-pressure air pipe, and the outer surface of the high-pressure air pipe is fixedly connected to the inner wall of the first solenoid valve.

[0007] In a preferred embodiment, a high-pressure gas valve is fixedly connected to the outer surface of the high-pressure gas pipe, a high-pressure gas interface is fixedly connected to the outer surface of the high-pressure gas valve, an air nozzle hose is fixedly connected to the outer surface of the high-pressure gas interface, and a high-pressure gas nozzle is fixedly connected to the outer surface of the air nozzle hose.

[0008] In a preferred embodiment, the outer surface of the low-pressure air nozzle is fixedly connected to the outer surface of the silo body.

[0009] In a preferred embodiment, the inner wall of the one-way valve is fixedly connected to the outer surface of the low-pressure intake pipe.

[0010] In a preferred embodiment, a high-pressure gas tank is fixedly connected to the outer surface of the first connecting pipe, and a control mechanism is fixedly connected to the outer surface of the high-pressure gas tank, the control mechanism including a second connecting pipe.

[0011] In a preferred embodiment, a high-pressure gas source chamber is fixedly connected to the outer surface of the second connecting pipe, and the outer surface of the second connecting pipe is fixedly connected to the outer surface of the high-pressure gas tank.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention features a low-pressure air path with multiple parallel nozzles, continuously blowing out low-pressure air to prevent minor blockages and ensure smooth material flow. The high-pressure air path selectively outputs high-pressure air to quickly remove severe and stubborn blockages. It supports three modes: low-pressure independent blockage removal, high-pressure independent blockage removal, and high-low pressure coordinated blockage removal, flexibly adapting to different blockage levels. This ensures thorough blockage removal without damaging the silo's inner wall. The single air source automatically starts and stops based on the high-pressure tank pressure, avoiding the idle energy consumption of traditional dual-air-source independent operation and reducing ineffective energy waste. The air source chamber maintains a standby state based on the high-pressure tank pressure, avoiding idle operation and eliminating the need for a separate low-pressure air source device, reducing equipment procurement costs. It also simplifies control logic, reducing potential failure points. The combination of a check valve and a pressure reducing valve ensures stable high-pressure to low-pressure conversion, preventing low-pressure air backflow and ensuring the reliability of dual-tank air storage. Both high- and low-pressure air paths are equipped with multiple nozzles, covering key areas of the silo's inner wall and improving the comprehensiveness of blockage removal.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 like Figures 1-5As shown, this utility model provides a technical solution: a high and low pressure single-source unblocking device, including a hopper body 1, a low-pressure air circuit mechanism 3 fixedly connected to the outer surface of the hopper body 1, the low-pressure air circuit mechanism 3 including a low-pressure air nozzle 31, the outer surface of the low-pressure air nozzle 31 fixedly connected to the outer surface of the hopper body 1, a low-pressure air pipe 32 fixedly connected to the outer surface of the low-pressure air nozzle 31, a second solenoid valve 33 fixedly connected to the outer surface of the low-pressure air pipe 32, a first low-pressure air tank 35 fixedly connected to the outer surface of the second solenoid valve 33, a low-pressure air valve 34 fixedly connected to the outer surface of the first low-pressure air tank 35, a low-pressure air inlet pipe 36 fixedly connected to the inner wall of the low-pressure air valve 34, a second low-pressure air tank 37 fixedly connected to the outer surface of the low-pressure air inlet pipe 36, and a connecting mechanism 4 fixedly connected to the outer surface of the low-pressure air inlet pipe 36. 4 includes a one-way valve 41, the inner wall of which is fixedly connected to the outer surface of the low-pressure intake pipe 36. A pressure reducing valve 42 is fixedly connected to the outer surface of the one-way valve 41. A first connecting pipe 43 is fixedly connected to the outer surface of the pressure reducing valve 42. A first solenoid valve 44 is fixedly connected to the outer surface of the first connecting pipe 43. A high-pressure air circuit mechanism 2 is fixedly connected to the inner wall of the first solenoid valve 44. The high-pressure air circuit mechanism 2 includes a high-pressure air pipe 21, the outer surface of which is fixedly connected to the inner wall of the first solenoid valve 44. A high-pressure air tank 5 is fixedly connected to the outer surface of the first connecting pipe 43. A control mechanism 6 is fixedly connected to the outer surface of the high-pressure air tank 5. The control mechanism 6 includes a second connecting pipe 61, the outer surface of which is fixedly connected to a high-pressure air source chamber 62. The outer surface of the second connecting pipe 61 is fixedly connected to the outer surface of the high-pressure air tank 5.

[0021] In this embodiment, a low-pressure air circuit mechanism 3 is fixedly connected to the outer surface of the silo body 1, and a connection hole is provided on the inner wall of the silo body 1. The end of a low-pressure air nozzle 31 passes through the connection hole and is fixedly connected to the inner wall. The low-pressure air nozzle 31 blows out the blockage on the inner wall of the silo body 1 with low-pressure air, so that the internal material discharge is unobstructed. Multiple low-pressure air nozzles 31 are connected in parallel to each other on the low-pressure air pipe 32, so that the blockage is cleared better when multiple low-pressure air nozzles 31 work together. The low-pressure air pipe 32 is connected to the first low-pressure air tank 35, and is connected to the second low-pressure air tank 35 through a three-way low-pressure air inlet pipe 36. Gas tank 37 increases the gas storage capacity of the low-pressure gas tank. A connecting mechanism 4 is fixedly connected to the other end of the low-pressure inlet pipe 36, and one end of the connecting mechanism 4 is fixedly connected to the high-pressure gas tank 5. The high-pressure gas tank 5 is connected to a pressure reducing valve 42 via a first connecting pipe 43, converting the high-pressure gas in the high-pressure gas tank 5 into low-pressure gas, which enters the one-way valve 41. The gas then enters the first low-pressure gas tank 35 and the second low-pressure gas tank 37 through the low-pressure inlet pipe 36 for storage. The second solenoid valve 33 controls the gas output to clear blockages or shuts off the system. The first connecting pipe 43 is a three-way valve, with one end connected to the high-pressure gas tank 5. On the compressed air tank 5, the high-pressure gas stored in the high-pressure tank 5 is input into the two low-pressure air tanks through the pressure reducing valve 42 and the one-way valve 41, while the other end is fixedly connected to the first solenoid valve 44. Through the high-pressure air pipe 21, which is connected to multiple high-pressure air valves 22, each high-pressure air valve 22 is connected to an air nozzle hose 24, so that the high-pressure air nozzle 25 is connected to the inner wall of the silo body 1. In this way, when there is a lot of blockage, the first solenoid valve 44 is opened, and the blockage can be cleared through the high-pressure air pipe 21 and the high-pressure air nozzle 25. After clearing, the silo body 1 is ready for use. If the operation is in good condition, simply close solenoid valve 44. When high and low pressure are required for cleaning, both solenoid valves can be opened simultaneously. The high and low pressure valves drive the actuators through the high and low pressure pipelines respectively to assist in cleaning. The high pressure gas tank 5 is connected to the high pressure gas source chamber 62 through the second connecting pipe 61. The high pressure gas source chamber 62 starts and stops according to the pressure of the high pressure gas tank 5, eliminating the need for a low pressure gas source device, reducing equipment procurement costs. A single gas source only needs to start and stop according to the pressure of the high pressure gas tank 5, avoiding the no-load operation of dual gas sources, reducing overall energy consumption. At the same time, reducing the control logic of a gas source will also reduce the number of failure points.

[0022] Example 2 like Figures 1-5 As shown, a high-pressure air valve 22 is fixedly connected to the outer surface of the high-pressure air pipe 21, a high-pressure air interface 23 is fixedly connected to the outer surface of the high-pressure air valve 22, an air nozzle hose 24 is fixedly connected to the outer surface of the high-pressure air interface 23, and a high-pressure air nozzle 25 is fixedly connected to the outer surface of the air nozzle hose 24.

[0023] In this embodiment, the high-pressure gas stored in the high-pressure gas tank 5 is input into the two low-pressure gas tanks through the pressure reducing valve 42 and the one-way valve 41, while the other end is fixedly connected to the first solenoid valve 44. The high-pressure gas is connected to the high-pressure gas pipe 21, which is connected to multiple high-pressure gas valves 22. Each high-pressure gas valve 22 is connected to a nozzle hose 24, so that the high-pressure gas nozzle 25 is connected to the inner wall of the silo body 1.

[0024] Working principle: like Figures 1-5 As shown, the high-pressure air source chamber 62 first automatically starts and stops according to the real-time pressure of the high-pressure air tank 5 to maintain a stable pressure inside the tank. The high-pressure air in the high-pressure air tank 5 enters the connecting mechanism 4 through the first connecting pipe 43, and is reduced to low-pressure air by the pressure reducing valve 42. The low-pressure air passes through the one-way valve 41 and the low-pressure air inlet pipe 36, and is stored in the first low-pressure air tank 35 and the second low-pressure air tank 37. When low-pressure clearing is required, the second solenoid valve 33 is opened, and the low-pressure air is distributed to multiple parallel low-pressure air nozzles 31 through the low-pressure air pipe 32, which spray out onto the inner wall of the silo body 1 to blow away light blockages and ensure smooth material discharge. When there are many blockages and the low-pressure clearing effect is insufficient, the first solenoid valve 44 is opened, and the high-pressure air in the high-pressure air tank 5 directly passes through the first connecting pipe 43 and the high-pressure air pipe 21, and is stored in the first low-pressure air tank 35 and the second low-pressure air tank 37. High-pressure air valve 22 and air nozzle hose 24 deliver high-pressure air to high-pressure air nozzle 25, spraying high-pressure air onto the inner wall of the silo to powerfully remove severe blockages. To enhance the unblocking effect, solenoid valve 44 and solenoid valve 33 can be opened simultaneously, with the two air nozzles working together to thoroughly remove blockages. After unblocking, the corresponding solenoid valve is closed. The air source chamber maintains a standby state based on the pressure of high-pressure air tank 5 to avoid no-load operation, eliminating the need for a low-pressure air source device, reducing equipment procurement costs, simplifying control logic, and reducing potential failure points. The combination of check valve 41 and pressure reducing valve 42 ensures a stable high-pressure to low-pressure process, prevents low-pressure air backflow, and ensures the reliability of dual-tank air storage. Multiple air nozzles are configured in both high and low-pressure air paths to cover key areas of the silo's inner wall, improving the comprehensiveness of unblocking.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
