Description

Technical Field

[0001] This invention relates to the field of hose purging technology, and in particular to a metal hose purging device. Background Technology

[0002] Metal hoses are widely used in the petrochemical industry. Regulations require annual inspections, including thorough cleaning, and additional cleaning is necessary when changing hose types. The industry typically uses steam cleaning followed by compressed air purging. However, after steam cleaning, residual condensate in the internal corrugated grooves of the metal hose is difficult to remove completely. For example, the corrugated grooves of a 6-inch metal hose are about 1 cm deep; larger hoses have deeper grooves, making them more difficult to clean. Moisture inside the hose can affect the quality of materials, posing a quality risk. Cleaning a 6-inch metal hose typically takes about 2 hours, resulting in significant energy consumption. For example, our company requires both an air compressor (132 kW) and a refrigerated dryer (6 kW) to run for 2 hours each, consuming 276 kWh of electricity. Storage areas require annual inspections, while docks require inspections twice a year. Steam cleaning and purging 115 hoses would require approximately 31,740 kWh of electricity, resulting in extremely high energy consumption, low cleaning efficiency, and high labor intensity. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a metal hose purger to solve the above problems.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A metal flexible hose purger includes a connecting pipe, a high-pressure rotating shaft connected to one end of the connecting pipe, and a rotating nozzle. The rotating nozzle is fixedly connected to the high-pressure nozzle of the high-pressure rotating shaft. The rotating nozzle is provided with at least two sets of circumferentially arranged fan-shaped nozzles. The orientation angle of the first set of fan-shaped nozzles is different from that of the second set of fan-shaped nozzles. The connecting pipe is provided with an expandable support for assisting the purger to move inside the metal flexible hose. The expandable support includes a first bushing fixedly sleeved on the connecting pipe, a second bushing movably sleeved on the connecting pipe, and multiple sets of first and second legs that cross each other in the middle and are hinged. One end of the first leg is hinged to the first bushing, and one end of the second leg is hinged to the second bushing. The other end of both the first and second legs is provided with a roller.

[0006] Furthermore, in the above-described invention, the first bushing and the second bushing are provided with multiple sets of U-shaped hinge seats in the circumferential direction, and one end of the first leg and the second leg are respectively connected to the first bushing and the second bushing through the U-shaped hinge seats.

[0007] Furthermore, in the above-described invention, the expandable support includes at least four sets of centrally intersecting and hinged legs 1 and 2.

[0008] Furthermore, in the above-described invention, the bushing two is also provided with a fastening bolt for fixing the bushing two, and the bushing two has a threaded hole, the fastening bolt passing through the threaded hole and abutting against the connecting pipe.

[0009] In the above-described invention, the nozzles on the first group of fan-shaped nozzles are arranged longitudinally along the central axis of the rotating nozzle, and the nozzles on the second group of fan-shaped nozzles are arranged laterally along the circumferential direction of the rotating nozzle.

[0010] In the above-mentioned invention, the number of nozzles in the first group of fan-shaped nozzles is 3-8, and the number of nozzles in the second group of fan-shaped nozzles is 3-8.

[0011] Furthermore, in the above-described invention, the nozzle is elliptical in shape.

[0012] Furthermore, in the above-described invention, a protective frame for protecting the rotating nozzle and the high-pressure rotating shaft is fixedly provided at one end of the connecting pipe near the rotating nozzle. The protective frame is formed by multiple sets of rectangular wire frames overlapping each other, and the rotating nozzle and the high-pressure rotating shaft are placed inside the protective frame.

[0013] Furthermore, in the above-described invention, the other end of the connecting pipe is also fixed with a high-pressure movable interface, which is connected to the air pipe of the air compressor.

[0014] The beneficial effects of this invention are:

[0015] 1. The use of metal hose blowers greatly shortens the hose blowing time, reducing the blowing time of a single hose from about 2 hours to about 6 minutes, improving work efficiency. In addition, the pressure of compressed air used is reduced from 6 kg to 3 kg, and the energy consumption required for blowing a single hose is reduced to 11.5 kWh, which greatly reduces energy costs and achieves the goal of energy saving and efficiency improvement.

[0016] 2. No need to lift or raise the hose during purging, reducing the workload and labor intensity of employees and improving work efficiency;

[0017] 3. The present invention can also be extended according to the size of the hose, and can be adapted to different hose inner diameters by using an extension bracket, which makes it highly applicable and easy to operate. Attached Figure Description

Detailed Implementation

[0022] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0023] Please see the appendix Figure 1-3 As shown, a metal hose blower includes a connecting pipe 1, a high-pressure rotating shaft 2 connected to one end of the connecting pipe 1, and a rotating nozzle 3. The high-pressure rotating shaft 2 can adopt an HS-type straight-through rotary joint. The rotating nozzle 3 is fixedly connected to the high-pressure nozzle of the high-pressure rotating shaft 2. The compressed high-pressure gas passes through the high-pressure rotating shaft 2 and makes the high-pressure rotating shaft 2 rotate, thereby driving the rotating nozzle 3 to rotate 360°. The high-pressure rotating shaft 2 can provide sufficient thrust to the housing of the rotating nozzle 3 for high-speed radial rotation, thereby improving the cleaning efficiency of the rotating nozzle 3.

[0024] As attached Figure 3 As shown, the rotating nozzle 3 is provided with at least two sets of circumferentially arranged fan-shaped nozzles. The orientation angle of the first set of fan-shaped nozzles 31 is different from that of the second set of fan-shaped nozzles 32. Preferably, the nozzle 5 is elliptical, so that the compressed air is dispersed in a fan shape, thereby expanding the blowing area. Because the orientation angle of the first set of fan-shaped nozzles 31 is different from that of the second set of fan-shaped nozzles 32, the angle and direction of the fan-shaped dispersion are different. Thus, the first set of fan-shaped nozzles 31 and the second set of fan-shaped nozzles 32 form a 360° no-dead-angle blowing of the metal hose.

[0025] Specifically, the number of nozzles in the first group of fan-shaped nozzles 31 is 3-8, preferably 6; the number of nozzles in the second group of fan-shaped nozzles 32 is 3-8, preferably 6; driven by the high-pressure rotating shaft 2, it is ensured that the inner surface of the metal hose is completely within the coverage of the purging track, so that each area is purged 12 times each time, which can effectively blow away the residual water in the hose groove.

[0026] In the above embodiments, preferably, the nozzles 5 on the first set of fan-shaped nozzles 31 are arranged longitudinally along the central axis of the rotating nozzle 3 for blowing the inner surface of the metal hose, and the nozzles 5 on the second set of fan-shaped nozzles 32 are arranged laterally along the circumferential direction of the rotating nozzle 3, especially for blowing the inside of the hose groove, ensuring that the water in the metal hose groove is fully blown away; through the two sets of fan-shaped nozzles and the special arrangement structure of the fan-shaped nozzles in this embodiment, the water in the metal hose can be blown away in a concentrated and effective manner, shortening the blowing time of the hose and improving the blowing efficiency.

[0027] Because the metal hose is quite long, to facilitate the purger's movement inside the metal hose, as shown in the attached... Figure 1 and attached Figure 2 As shown, the connecting pipe 1 is equipped with an expandable bracket 4 to assist the purger in moving within the metal hose. The expandable bracket 4 includes a first bushing 41 fixedly sleeved on the connecting pipe 1, a second bushing 42 movably sleeved on the connecting pipe 1, and multiple sets of cross-shaped and hinged support legs 43 and 44. Preferably, in this embodiment, the expandable bracket 4 includes at least four sets of cross-shaped and hinged support legs 43 and 44, which can support the purger and ensure that the rotating nozzle 3 is always in a position where... The blower evenly blows into the center of the metal hose. One end of the first support leg 43 is hinged to the first bushing 41, and one end of the second support leg 44 is hinged to the second bushing 42. The other ends of the first support leg 43 and the second support leg 44 are equipped with rollers 45. The rollers 45 on the first support leg 43 and the second support leg 44 respectively abut against the inside of the metal hose. The blower moves inside the metal hose through the rollers 45, which improves the convenience of the blower in operating inside the metal hose, shortens the blowing time of the hose, and effectively reduces energy waste.

[0028] Among them, the bushing 41 and the bushing 42 are provided with multiple sets of U-shaped hinge seats 46 in the circumferential direction, and one end of the support leg 43 and the support leg 44 are respectively hinged to the bushing 41 and the bushing 42 through the U-shaped hinge seats 46.

[0029] The bushing 42 is also provided with a fastening bolt 47 for fixing the bushing 42. The bushing 42 has a threaded hole 48, and the fastening bolt 47 passes through the threaded hole 48 and abuts against the connecting pipe 1.

[0030] Specifically, the blower can adapt to metal hoses of different diameters via the expandable bracket 4. The blower is placed at one end of the metal hose, and the fastening bolt 47 is loosened to allow the second bushing 42 to slide. The second bushing 42 is moved towards the first bushing 41, causing the second support leg 44 on the second bushing 42 to rotate. The first support leg 43 and the second support leg 44 expand outwards until the rollers 45 on the four sets of first support legs 43 and second support legs 44 abut against the inner surface of the metal hose. The movement of the second bushing 42 is then stopped, and the fastening bolt 47 is tightened to fix the second bushing 42. This achieves the ability to adjust the blower's fit according to the size of the metal hose, making it widely applicable and easy to operate. Simply place the blower inside the metal hose and drag it with a rope or directly drag the compressed air pipe connected to the other end of the connecting pipe 1 to complete the blowing process. There is no need to lift or raise the metal hose during blowing, reducing the workload and labor intensity of employees.

[0031] In the above embodiments, preferably, a protective frame 6 is fixedly provided at one end of the connecting pipe 1 near the rotating nozzle 3 to protect the rotating nozzle 3 and the high-pressure rotating shaft 2. The rotating nozzle 3 and the high-pressure rotating shaft 2 are placed inside the protective frame 6 so that the rotating nozzle 3 will not touch the inner wall of the hose, reducing the wear of the equipment and improving the service life of the equipment. The protective frame 6 is formed by multiple sets of rectangular wire frames overlapping each other, which can play a role in preventing collisions and will not block the blowing of the rotating nozzle 3.

[0032] The other end of the connecting pipe 1 is also fixed with a high-pressure movable interface 7, which is connected to the air pipe of the air compressor.

[0033] Using the blower in this technical solution can reduce the blowing time for each hose from 2 hours to 4-6 minutes, and the pressure of the compressed air used can be reduced from 6 kg to 3 kg. Taking our company as an example, the electricity consumption per hose can also be reduced from 276 kWh to 11.5 kWh, which greatly improves work efficiency and saves electricity costs.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
