Technical Field
[0001] This utility model belongs to the field of marine oil engineering construction, and in particular relates to a multifunctional compressed air suction device. Background Technology
[0002] In the process of offshore oil engineering development, the construction environment of enclosed compartments and confined spaces is special, and the construction operation requirements are strict. The compartments and confined spaces can only be cleaned by connecting the power supply to the equipment. Severe weather brings a certain amount of water accumulation to the ship's hold, and the debris and dust on site and in the compartments are difficult to clean. Large-area compartment construction requires the support of a large ventilation system.
[0003] Due to limited site space, which is further occupied by a large amount of ventilation system, the construction space is even smaller. Personnel entering the construction area will pose a safety hazard. The cleaning equipment is powered by an external power source, which poses a risk of electric shock to construction personnel due to equipment leakage. In addition, the additional external power source will increase the difficulty and cost of construction. There is a large amount of usable compressed air available on site.
[0004] Therefore, there is an urgent need to design a multifunctional compressed air suction device to solve the problem of safely cleaning enclosed chambers and confined spaces mentioned above. Utility Model Content
[0005] To address the technical issues mentioned in the background art, such as the confined construction space posing a safety hazard to personnel entering the construction area, and the risk of electric shock to construction workers due to equipment leakage caused by the external power supply of the cleaning equipment, a multi-functional compressed air suction device is provided to solve the problem of safely cleaning confined chambers and restricted spaces.
[0006] To achieve the above objectives, the specific technical solution of the multifunctional compressed air suction device of this utility model is as follows:
[0007] A multifunctional compressed air suction device includes an outlet pipe, an air chamber inside the outlet pipe, an air duct between the air chamber and the outlet pipe, an air inlet pipe connected to the outlet pipe, an air inlet on the air chamber, compressed air in the air inlet flowing into the air chamber, a main connecting pipe connected to the air chamber, and a suction supply structure connected to the main connecting pipe, the compressed air flowing from the air inlet to the outlet of the air chamber, so that the material to be discharged in the suction supply structure is discharged from the outlet of the air chamber.
[0008] Furthermore, the intake pipe includes a first intake pipe and a second intake pipe, both of which are connected to the outer wall of the outlet pipe, and both the first intake pipe and the second intake pipe are equipped with intake valves.
[0009] Furthermore, the side of the outlet pipe that connects to the first and second air inlets is conical, and the distance between the outlet pipe and the air cavity is uniform.
[0010] Furthermore, the air cavity has an air inlet side with a vertically welded insertion pipe. The outer wall of the insertion pipe is welded to the outlet pipe to form a closed air passage between the outlet pipe and the air cavity. The end of the insertion pipe away from the air cavity is inserted into the main connecting pipe.
[0011] Furthermore, a first retaining ring is fitted onto the insertion tube, and the main connecting tube is inserted into one end of the insertion tube and fixed by the first retaining ring.
[0012] Furthermore, the end of the main connecting pipe furthest from the insertion pipe is connected to the suction and supply structure, and the suction and supply structure is fixed to the main connecting pipe by a second retaining ring.
[0013] Furthermore, a fixing buckle is connected to the main connecting pipe, which fixes the main connecting pipe in the discharge area so that the waste to be discharged can be discharged at a fixed point.
[0014] Furthermore, the suction structure includes a water suction pipe, which is inserted into one end of the main connecting pipe and fixed by a second retaining ring, so that the water in the water suction pipe flows along the main connecting pipe to the air chamber.
[0015] Furthermore, the suction structure also includes a suction pipe, one end of which is inserted into the main connecting pipe, and the other end of the suction pipe away from the main connecting pipe is connected to a duckbill.

[0017] The multifunctional compressed air suction device of this invention has the following advantages:
[0018] Utilizing the Venturi effect, an air chamber is installed inside the outlet pipe. An inlet pipe connected to the outlet pipe draws compressed air into the air chamber through the inlet, creating an adsorption effect and causing the air to exit through the outlet.

For example, in the claims, any of the claimed embodiments can be used in any combination.
[0025] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This invention describes a multifunctional compressed air suction device.
[0026] like Figure 1 As shown, the multifunctional compressed air suction device of this utility model includes an outlet pipe 1, an air chamber 2 inside the outlet pipe 1, an air duct 3 between the air chamber 2 and the outlet pipe 1, an air inlet pipe connected to the outlet pipe 1, an air inlet 6 on the air chamber 2, compressed air in the air inlet pipe flows into the air chamber 2 along the air inlet 6, a main connecting pipe 8 is connected to the air chamber 2, a suction supply structure 9 is connected to the main connecting pipe 8, and compressed air flows along the air inlet 6 of the air chamber 2 to the outlet 10 of the air chamber 2, so that the material to be discharged in the suction supply structure 9 is discharged along the outlet 10 of the air chamber 2.
[0027] Utilizing the Venturi effect, an air chamber 2 is installed inside the outlet pipe 1. Compressed air flows into the air chamber 2 through the inlet 6 of the inlet pipe connected to the outlet pipe 1, creating an adsorption effect and causing the air to exit through the outlet 10 of the air chamber 2. A suction supply structure 9 is connected to the air chamber 2 to allow water, dust, or waste gas within the suction supply structure 9 to be discharged through the outlet 10. This application adsorbs welding fumes, welding slag on the ground, and accumulated water, greatly improving work efficiency, reducing construction costs, and lowering safety risks. It can be easily used by connecting to an air belt inside the cabin.
[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the air intake pipe includes a first air intake pipe 4 and a second air intake pipe 5. Both the first air intake pipe 4 and the second air intake pipe 5 are connected to the outer wall of the outlet pipe 1. Both the first air intake pipe 4 and the second air intake pipe 5 are equipped with an air intake valve 11. The side of the outlet pipe 1 that connects to the first air intake pipe 4 and the second air intake pipe 5 is conical. The outlet pipe 1 and the air chamber 2 are evenly spaced.
[0029] The air chamber 2 has an air inlet 6 and a vertically welded insertion pipe 7 on one side. The outer wall of the insertion pipe 7 is welded to the outlet pipe 1 so that a closed air passage 3 is formed between the outlet pipe 1 and the air chamber 2. The end of the insertion pipe 7 away from the air chamber 2 is inserted into the main connecting pipe 8. A first retaining ring 12 is fitted on the insertion pipe 7. The end of the main connecting pipe 8 inserted into the insertion pipe 7 is fixed by the first retaining ring 12.
[0030] In this embodiment, preferably, the first air intake pipe 4 and the second air intake pipe 5 are the same in shape and size, both the first air intake pipe 4 and the second air intake pipe 5 are welded to the outer wall of the outlet pipe 1, and the first air intake pipe 4 and the second air intake pipe 5 are symmetrically arranged.
[0031] An air intake valve 11 is installed on both the first air intake pipe 4 and the second air intake pipe 5. The first air intake pipe 4 and the second air intake pipe 5 are connected to the air belt in the cabin. The air intake valve 11 can not only control the inflow of compressed air, but also prevent compressed air from flowing into the outlet pipe 1 when the outlet pipe 1 is not fixed in place, so as to prevent the outlet pipe 1 from flying out and injuring the construction personnel. Using compressed air as power is environmentally friendly, energy-saving, safe, simple to operate, has a large emission capacity, is lightweight, and small in size, and achieves the purpose of being convenient to use and portable.
[0032] Preferably, the outlet pipe 1 is divided into two sections, one being a cylinder and the other a cone. The first air inlet pipe 4 and the second air inlet pipe 5 are both welded to one side of the cone of the outlet pipe 1, and a uniform air passage 3 is formed between the air cavity 2 inside the outlet pipe 1 and the outlet pipe 1 to allow compressed air to flow into the air cavity 2.
[0033] The air chamber 2 has multiple air inlets 6. The air chamber 1 has a pipe 7 welded vertically to one side of the air inlet 6. Preferably, the multiple air inlets 6 of the air chamber 2 are evenly distributed with the pipe 7 as the center. The outer wall of the pipe 7 is welded to the outlet pipe 1, so that a sealed air passage 3 is formed between the outlet pipe 1 and the air chamber 2. The compressed air flowing in from the first air inlet pipe 4 and the second air inlet pipe 5 flows into the air chamber 2 only through the air inlet 6.
[0034] The end of the insertion tube 7 away from the air cavity 2 is inserted into the main connecting tube 8. The insertion tube 7 is fitted with a first retaining ring 12. After the main connecting tube 8 is inserted into the insertion tube 7, the main connecting tube 8 is fixed to the insertion tube 7 by the first retaining ring 12. The non-welded fixed connection method facilitates the replacement of the main connecting tube 8 later, or the main connecting tube 8 can be separated from the outlet tube 1 and the outlet tube 1 and the main connecting tube 8 can be cleaned.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the end of the main connecting pipe 8 away from the insertion pipe 7 is connected to the suction and supply structure 9. The suction and supply structure 9 is fixed to the main connecting pipe 8 by the second retaining ring 13. A fixing buckle 14 is connected to the main connecting pipe 8. The fixing buckle 14 fixes the main connecting pipe 8 in the discharge area so that the material to be discharged can be discharged at a fixed point.
[0036] In this embodiment, preferably, the end of the main connecting pipe 8 away from the insertion pipe 7 is an open port, the suction structure 9 is connected to the main connecting pipe 8, and the suction structure 9 is fixed by the second retaining ring 13 sleeved on the main connecting pipe 8.
[0037] The main connecting pipe 8 is fitted with a fixing buckle 14, which fixes the main connecting pipe 8 in the designated discharge area. This facilitates the adjustment of the discharge point and discharge direction of the material to be discharged, and avoids manual operation during construction, thus ensuring construction safety.
[0038] Furthermore, such as Figure 1 As shown, the suction structure 9 includes a water suction pipe 15, one end of which is inserted into the main connecting pipe 8 and fixed by a second retaining ring 14, so that the water in the water suction pipe 15 flows along the main connecting pipe 8 to the air chamber 2; the suction structure also includes a dust suction pipe, one end of which is inserted into the main connecting pipe 8, and the end of the dust suction pipe away from the main connecting pipe 8 is connected to a duckbill. The main connecting pipe 8 and the dust suction pipe are fixed by a second retaining ring 12, so that the dust in the dust suction pipe flows along the main connecting pipe 8 to the air chamber 2; the suction structure also includes an air suction pipe, one end of which is inserted into the main connecting pipe 8 and fixed by a second retaining ring 12, so as to realize exhaust ventilation.
[0039] As a preferred embodiment, when it is necessary to clean up the accumulated water, the suction pipe 15 is inserted into the main connecting pipe 8 and fixed to the main connecting pipe 8 by the second retaining ring 12. The length of the main connecting pipe 8 is 1-3 meters. The compressed air in the air chamber 2 drives the water in the suction pipe 15 into the air chamber 2 and then discharges it through the outlet 10 of the air chamber 2. The suction force is 3-7 MPa and the flow rate is 1-2 tons / hour.
[0040] As a preferred embodiment, when it is necessary to remove dust, the suction pipe is inserted into the main connecting pipe 8 and fixed to the main connecting pipe 8 by the second retaining ring 12. A duckbill is provided at the end of the suction pipe away from the main connecting pipe 8. The worker holds the duckbill above the dust. The compressed air in the air chamber 2 drives the dust in the suction pipe into the air chamber 2 and then discharges it through the outlet 10 of the air chamber 2. The head is between 1 and 2 meters.
[0041] As a preferred embodiment, when ventilation is required, the suction pipe is inserted into the main connecting pipe 8 and fixed to the main connecting pipe 8 by the second retaining ring 12. The compressed air in the air chamber 2 drives the welding waste gas in the suction pipe into the air chamber 2 and then discharges along the outlet 10 of the air chamber 2.
[0042] The assembly and construction principle of the multifunctional compressed air suction device in this utility model is as follows:
[0043] The first air inlet pipe 4 and the second air inlet pipe 5 are welded to the outlet pipe 1. Compressed air enters the outlet pipe 1 through the first air inlet pipe 4 and the second air inlet pipe 5. The compressed air flows into the air chamber 2 through the air inlet 6 along the air duct 3, generating an adsorption effect. The air is discharged through the outlet 10 of the air chamber 2. The main connecting pipe 8 is inserted into the plug pipe 7 connected to the air chamber 2. By changing the supply and suction structure 9 inserted into the main connecting pipe 8, water, dust or exhaust gas can be discharged at a fixed point through this suction device.
[0044] Based on the multifunctional compressed air suction device, this utility model utilizes the Venturi effect to set up an air chamber 2 inside the outlet pipe 1. The first air inlet pipe 4 and the second air inlet pipe 5, which are connected to the outlet pipe 1, allow compressed air to flow into the air chamber 2 along the air inlet 6, thereby generating an adsorption effect and causing the air to be discharged along the outlet 10 of the air chamber 2. The air chamber 2 is connected to a suction supply structure 9 so that water, dust or exhaust gas in the suction supply structure can be discharged along the outlet.
[0045] This application connects to different accessories via the main connecting pipe 8 to form different functions, perfectly solving the different needs of construction in sealed chambers. This method not only improves safety but also greatly reduces the difficulty of operation and labor intensity. It is easy to fix, greatly reduces the production cost of enterprises, and improves work efficiency.
