Description

Technical Field

[0001] The present invention belongs to the technical field of cargo hold cleaning devices, and in particular relates to a gas-liquid coupled spiral flow-guiding pressurized injection device. Background Art

[0002] Bulk carriers are efficient and convenient transport equipment that can transport a variety of goods, such as coal, crops, livestock, etc. Considering economic benefits, bulk carriers will transport a variety of goods. In order to avoid contamination of goods and reduce the value of goods when changing the type of goods, the cabin is generally cleaned before loading the goods.

[0003] There are generally several ways to clean the cabin. The first is to use a high-pressure water gun for direct flushing, which is mostly done by relying on special fixed cleaning equipment on the shore. It is highly efficient, but because most of the equipment is a fixed water gun and there are design defects, the water gun pressure is insufficient and there are many blind spots in the cleaning process. The second is to build a scaffold at the bottom of the cargo ship, climb the scaffold manually, and use brushes, water pipes and other equipment for cleaning. The third is to use a person climbing a ladder to clean. The latter two cleaning methods require a lot of manpower and material resources, and the cleaning efficiency is relatively low. In addition, during the cleaning process, workers need to climb the scaffold and ladder many times, which is very dangerous.

[0004] In summary, the existing high-pressure water gun technology is not mature enough and has the following problems:

[0005] 1. Most high-pressure water guns are fixed equipment, which are bulky and difficult to move, and are inconvenient to use. The cargo ship must be docked at a fixed position for cleaning. In addition, since the equipment is fixed, there are many dead corners in the cargo hold that are difficult to clean. Locations far away from the equipment are also prone to poor cleaning due to the decrease in water flow speed.

[0006] 2. In order to ensure the flexibility and portability of the portable high-pressure water gun, the performance of the general equipment will be greatly reduced. Most portable high-pressure water guns have a short range and low water pressure, and are only suitable for use in smaller cabins; for taller cabins, there is a problem of low water pressure and insufficient cleaning.

[0007] Therefore, it is necessary to provide an improved gas-liquid coupled spiral flow-guiding boost injection device to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to provide a gas-liquid coupled spiral guide booster injection device, which uses a spiral guide tube to allow compressed air to further boost the compressed water flow in multiple stages to form a high-pressure flow water column, thereby increasing the range of the water gun. The present invention is a convenient and practical marine booster cleaning water gun.

[0009] To achieve the above-mentioned purpose, the present invention provides a gas-liquid coupled spiral flow-guiding pressurized injection device, comprising an air intake unit, a water intake unit, a gas-liquid mixing unit and an injection unit;

[0010] The gas-liquid mixing unit includes a spiral guide tube, one end of which is connected to the water inlet unit, the other end is connected to the injection unit, and the middle part is connected to the air inlet unit; the inner wall of the spiral guide tube is a multi-stage spiral guide tube structure, so that the air flow of the air inlet unit and the water flow of the water inlet unit are mixed and further pressurized.

[0011] Furthermore, the multi-stage spiral flow guide pipe is opened on the inner wall of the spiral flow guide pipe in the form of internal threads.

[0012] Furthermore, one end of the spiral guide tube connected to the injection unit is a conical structure with a gradually decreasing diameter.

[0013] Furthermore, the connection portion between the air intake unit and the spiral flow guide pipe is provided at the multi-stage spiral flow guide pipe.

[0014] Furthermore, the gas-liquid mixing unit also includes a steam reduction pipe connected to the outlet end of the spiral guide pipe, the steam reduction pipe is connected to the injection unit, the steam reduction pipe is a conical structure, and the diameter gradually decreases from one end of the spiral guide pipe to one end of the injection unit.

[0015] Furthermore, the gas-liquid mixing unit also includes a sleeve sleeved on the outside of the spiral flow guide tube, and the air intake unit is connected to the spiral flow guide tube through the sleeve.

[0016] Furthermore, the air intake unit includes a spiral supercharged air intake pipe, and the spiral supercharged air intake pipe includes an air inlet and an air outlet; a ball valve and a compressed air regulating valve are arranged at the air inlet, and the air outlet is connected to the spiral guide pipe.

[0017] Furthermore, the water inlet unit includes a transition pipe connected to the spiral guide pipe, and the inlet end of the transition pipe is provided with a fire water valve interface and a compressed water flow regulating valve.

[0018] Furthermore, the spraying unit includes a replaceable nozzle.

[0019] Furthermore, the outer wall of the sleeve is provided with a rotatable hydraulic base and a movable triangular bracket for adjusting the spraying angle of the spraying unit.

[0020] In general, the above technical solution conceived by the present invention has the following technical advantages compared with the prior art:

[0021] 1. The gas-liquid coupled spiral guide booster injection device provided by the present invention uses a spiral guide tube when mixing compressed air and high-pressure water flow, so that the gas-liquid mixing is more uniform, the high-pressure water is pressurized, the water flow pressure is increased, and the range of the water gun is increased.

[0022] 2. The present invention transforms the air intake pipe into a spiral supercharged air intake pipe, thereby increasing the pressure of the incoming air, and at the same time adds a control valve so that the water gun pressure can be controlled in combination with specific usage scenarios.

[0023] 3. The present invention arranges a conical steam reduction pipe at the end of the spiral guide pipe to compress the water flow and further pressurize the gas-liquid mixture.

[0024] 4.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] See also Figure 1-3 The present invention provides a gas-liquid coupled spiral guide boost injection device, comprising an air intake unit, a water intake unit, a gas-liquid mixing unit and a spray unit; the air intake unit and the water intake unit spray high-pressure water flow through the spray unit after the gas-liquid mixing unit mixes, thereby realizing remote cleaning.

[0032] Among them, the gas-liquid mixing unit includes a spiral guide tube 8, one end of the spiral guide tube 8 is connected to the water inlet unit, the other end is connected to the injection unit, and the middle part is connected to the air inlet unit; the inner wall of the spiral guide tube 8 is a multi-stage spiral guide tube 9 (that is, a plurality of spirals spaced apart on the inner wall of the spiral guide tube 8) structure, so that the airflow of the air inlet unit and the water flow of the water inlet unit are mixed and further pressurized.

[0033] like Figure 3 The spiral guide tube 8 is a specific cylindrical body, and the multi-stage spiral guide tube 9 is opened in the form of an internal thread on the inner wall of the cylindrical body of the spiral guide tube 8. After the water flows into the cylindrical body, it flows through the multi-stage spiral guide tube 9 to form a vortex to increase the pressure. Under the impetus of the compressed airflow, it further advances along the multi-stage spiral guide tube 9 toward the nozzle end, and the pressure gradually increases. The pressurization effect is better than the existing gas-liquid mixing effect.

[0034] In particular, the end of the spiral guide pipe 8 connected to the injection unit is a conical structure with a gradually decreasing diameter, which can compress the water flow and increase the water flow pressure. The connection part between the air intake unit and the spiral guide pipe 8 is opened at the multi-stage spiral guide pipe 9.

[0035] The gas-liquid mixing unit also includes a steam reduction pipe 10 connected to the outlet end of the spiral guide pipe 8. The steam reduction pipe 10 is connected to the injection unit. The steam reduction pipe 10 is a conical structure, and its diameter gradually decreases from one end of the spiral guide pipe 8 to one end of the injection unit, thereby compressing the water flow and further pressurizing the gas-liquid mixture.

[0036] The gas-liquid mixing unit further includes a sleeve 4 sleeved on the outside of the spiral guide tube 8, and the air intake unit passes through the sleeve 4 and communicates with the spiral guide tube 8. The sleeve 4 is used to improve the durability of the water gun and prevent the spiral guide tube 8 from being worn.

[0037] like Figure 2The air intake unit includes a spiral supercharged air intake pipe 3, which includes an air inlet and an air outlet; a ball valve 1 and a compressed air regulating valve 2 are arranged at the air inlet, and the air outlet is connected to the spiral guide pipe 8. One end of the ball valve 1 is connected to the compressed air, and the other end is connected to the air intake pipe. The air intake pipe is internally provided with a spiral supercharged air intake pipe 3. When the air passes through the spiral supercharged air intake pipe 3, the pressure of the compressed air is further increased.

[0038] Furthermore, the water inlet unit includes a transition pipe 7 connected to the spiral guide pipe 8, and the inlet end of the transition pipe 7 is provided with a fire water valve interface 5 and a compressed water flow regulating valve 6. One end of the fire water valve interface 5 is connected to the fire hose, and the other end is connected to the spiral guide pipe 8. After the compressed water flows from the fire hose into the spiral guide pipe 8, the water flow pressure increases. It is mixed with compressed air in the gas-liquid mixer to form a high-pressure gas-liquid mixture, which further increases the pressure of the water flow. After multiple pressurizations through the multi-stage spiral guide pipe 8, the conical steam reduction pipe 10 and the replaceable nozzle 11, the water flow is pressurized several times. A high-pressure stream water column is formed.

[0039] The present invention partially redesigns the portable bulk carrier tank washing high-pressure water gun, transforms the air intake pipe into a spiral supercharged air intake pipe 3, so that the incoming air pressure is increased, and adds control valves (compressed air regulating valve 2 and compressed water flow regulating valve 6) so that the water gun pressure can be controlled in combination with specific usage scenarios. At the same time, a spiral guide tube 8 is used when mixing compressed air and high-pressure water flow to make the gas-liquid mixing more uniform, supercharge the high-pressure water, increase the water flow pressure, and increase the range of the water gun.

[0040] In particular, the spraying unit comprises a replaceable nozzle 11 .

[0041] Furthermore, a rotatable hydraulic base 12 and a movable triangular bracket 13 are provided on the outer wall of the sleeve 4 to adjust the spray angle of the spray unit. The water gun can be moved and fixed in the cargo hold by adjusting the rotatable hydraulic base 12 and the triangular bracket 13 to achieve cleaning without dead angles, and the nozzle can be replaced according to the usage scenario.

[0042] In some specific embodiments, Figure 1As shown, the present invention provides a portable cargo ship tank cleaning high-pressure water gun including a ball valve 1, a compressed air regulating valve 2, a spiral supercharged air intake pipe 3, a sleeve 4, a fire water valve interface 5, a compressed water flow regulating valve 6, a transition pipe 7, a spiral guide pipe 8, a multi-stage spiral guide pipe 9, a steam reduction pipe 10, a replaceable nozzle 11, a rotatable hydraulic base 12, and a movable triangular bracket 13. Among them, the ball valve 1 is fixed to one end of the spiral supercharged air intake pipe 3, the compressed air regulating valve 2 is added to the spiral supercharged air intake pipe 3, the other end of the spiral supercharged air intake pipe 3 is fixed to the sleeve 4, and the fire water valve interface 5 is fixed to the outer end of the transition pipe 7. The transition pipe 7 is sheathed with a spiral guide pipe 8 (i.e., the front section of the spiral guide pipe 8 is sheathed in the transition pipe 7, and mainly circulates water), the middle section of the transition pipe 7 is equipped with a compressed water flow regulating valve 6, the spiral guide pipe 8 and the spiral supercharged air intake pipe 3 merge in the middle of the spiral guide pipe 8 (preferably merge in the spiral section of the spiral guide pipe 8), one end of the steam reduction pipe 10 is connected to the other end of the sleeve 4, and the other end of the steam reduction pipe 10 is connected to the replaceable nozzle 11. The lower end of the sleeve 4 is fixed on a rotatable hydraulic base 12, and the lower part of the rotatable hydraulic base 12 is connected to a movable triangular bracket 13. The above-mentioned fire water valve interface 5 is a fire fast pipe thread interface. The conical steam reduction pipe 10 plays the role of compressing the water flow and further pressurizing the gas-liquid mixture.

[0043] In this embodiment, the ball valve 1 is connected to the spiral supercharged air intake pipe 3 via threads.

[0044] In this embodiment, the spiral supercharged air intake pipe 3 is welded to the sleeve 4 .

[0045] In this embodiment, the fire water valve interface 5 is connected to the transition pipe 7 through threads.

[0046] In this embodiment, the spiral flow guide tube 8 is stuck in the hollow cavity inside the sleeve 4 .

[0047] In this embodiment, the spiral flow guide tube 8 is connected to the multi-stage spiral flow guide tube 9 through threads.

[0048] In this embodiment, the steam reduction pipe 10 is connected to the replaceable nozzle 11 through a threaded connection.

[0049] In this embodiment, the fire water valve interface 5 is connected to the fire water pipe on board, and the ball valve 1 is connected to the compressed air on board.

[0050] In this embodiment, a rotatable hydraulic base 12 is provided in the middle of the sleeve 4, and the rotatable hydraulic base 12 is connected to a movable tripod 13. It can rotate 360 ​​degrees, and the elevation angle can reach 85 degrees. The tripod is composed of an equilateral triangle, and a lockable roller is installed at the bottom of the bracket. The angle between the tripods is 120 degrees. The roller can be moved in the horizontal direction to adjust the hydraulic base 12 to move and rotate in the vertical direction. In order to achieve the purpose of rust prevention and lightness, the tripod 13 is made of stainless steel and aluminum.

[0051] The ball valve 1 is used to filter the air source, the spiral booster air intake pipe 3 is connected to the air source and then provides the air source to the water gun, the sleeve 4 plays a connecting role, the fire water valve interface 5 is connected to the water source to provide the water source to the water gun, the transition pipe 7 plays a connecting role, the spiral guide pipe 8 guides the water flow to be ejected in a spiral shape while pressurizing, the multi-stage spiral guide pipe 9 fully mixes the compressed water flow and the compressed air, so that the air flow further pressurizes the water flow, the steam reduction pipe 10 plays a connecting role, and the replaceable nozzle 11 plays the role of spraying water flow. At the same time, the replaceable nozzle 11 can be replaced according to the specific usage scenario. When cleaning closer, use a 40° nozzle, adjust the valves of the spiral booster air intake pipe 3 and the water pipe, appropriately reduce the pressure of the gas-liquid mixture, form a larger water mist surface and cleaning range, and speed up the cleaning speed; when cleaning higher and farther positions and difficult-to-clean dirt, the 15° nozzle can be replaced. At this time, the water flow beam is thinner, the impact force is stronger, and it is easier to clean.

[0052] The pressure of the fire water connected to the fire water valve interface 5 is 0.3MPa to 0.6MPa, and the pressure of the compressed air connected to the ball valve 1 is 0.35MPa to 0.6MPa. After further pressurization through the multi-stage spiral diversion and the steam reduction pipe 10, the outlet water column can rotate and the maximum vertical range can reach 50 meters, achieving the purpose of remote high-pressure tank washing. When the maximum vertical range is 50 meters, the outlet water flow rate is not less than 100L / min. The water gun of the cleaning machine can rotate 360 ​​degrees, the maximum elevation angle can reach 85 degrees, and the assembly weight is less than 30 kilograms.

[0053] In summary, the gas-liquid coupled spiral flow-guiding boost injection device provided by the present invention can increase the range of the water gun to a certain extent while ensuring the portability of the water gun. The device has a simple structure, is portable and flexible, and can be used for cleaning a variety of bulk carriers, thereby solving a series of bulk carrier cabin cleaning problems and achieving safer and more efficient cleaning work. At the same time, this water gun can also be used in a variety of other scenarios, such as cleaning ordinary trucks. By appropriately changing the shape of the nozzle, it can also be used in forestry, agriculture, and urban road cleaning.
