Description

Technical Field

[0001] The utility model relates to the technical field of cavitation jets, and more specifically to a cavitation jet generating device and cleaning equipment. Background Art

[0002] At present, kerosene immersion method is mostly used for industrial oil pollution, which has low cleaning efficiency, high cost and serious environmental pollution; shot blasting or laser burning is mostly used for metal rust removal, but the cost of rust removal is high and metal dust will be generated to pollute the environment; mechanical grinding method is mostly used for paint coating, which is labor-intensive and time-consuming, and grinding will produce a large amount of toxic dust and a harsh working environment.

[0003] The emergence of cavitation jet technology provides a green and environmentally friendly cleaning method to solve the above problems. Pulse cavitation jet is a new type of high-pressure water jet technology that has emerged in recent years. Its erosion ability is several times better than that of ordinary jets under the same pump pressure. This technology is widely used in wastewater degradation, material surface hardening, shipping equipment cleaning, industrial cleaning and oil drilling. The cavitation jet generating device usually includes a nozzle, an air source or a liquid source, a control system and a casing. When performing maintenance and cleaning on the bogies and brake beam end shafts of railway freight cars in the shipping field, cavitation jet technology is often used for maintenance and flushing cleaning.

[0004] The existing cavitation jet generating device and cleaning equipment still have the following problems: when the existing cavitation jet cleaning equipment is used to flush the steel structure, the cleaning liquid and water are usually mixed, so that the mixed cleaning water can be used to flush the steel structure better. However, before the flushing, the cleaning liquid and the flushing water are often required to be preliminarily mixed, which undoubtedly increases the labor intensity of the personnel and brings certain troubles to the cleaning efficiency. In addition, the existing cavitation jet cleaning equipment is very dependent on ultrasonic vibration, and it is extremely difficult to achieve a good cavitation reaction in a short time, which brings many inconveniences to the use;

[0005] Moreover, when the shipping industry performs maintenance and cleaning on railway freight car bogies and brake beam end axles, since railway freight car bogies and brake beam end axles are often large in size, the cleaning coverage is small during cleaning, and when cleaning some narrow spaces, the flushing spray head of the existing cavitation jet cleaning equipment has poor steering flexibility, which causes many inconveniences in actual use.

[0006] In view of this, we propose a cavitation jet generating device and a cleaning equipment. Utility Model Content

[0007] 1. Technical issues to be solved

[0008] The purpose of the utility model is to provide a cavitation jet generating device and a cleaning device to solve the problems raised in the above background technology.

[0009] 2. Technical solution

[0011] Preferably, a water guide groove is provided on the outer wall of the connecting sleeve, and a rotation groove is provided on the side wall of the connecting sleeve.

[0012] Preferably, a rotating cylindrical block is rotatably connected inside the rotating groove, and a ball bearing is arranged on the circumferential outer wall at the end of the rotating cylindrical block.

[0013] Preferably, a connecting rod is provided on the side wall of the rotating cylindrical block, and blades are provided on the circumferential outer wall of the connecting rod.

[0014] Preferably, a cleaning liquid inlet pipe is provided at the top of the connecting tube one, and a water inlet pipe is provided on the front and rear circumferential outer walls of the connecting tube one.

[0016] Preferably, a high-pressure injection head is provided on the outer wall of the sealing cylinder, and a plurality of injection ports of the high-pressure injection head are all opened obliquely in one direction.

[0018] Preferably, the cleaning equipment includes the aforementioned cavitation jet generating device.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the utility model are as follows: when in use, an external high-pressure water pump can be used to allow cleaning water to enter from the water inlet pipe, and then the external water pump can be used to inject cleaning liquid from the cleaning liquid inlet pipe. Since the multiple water inlet pipes and the cleaning liquid inlet pipe have a certain inclination after extending into the interior of the connecting tube, they can be vortex-rotated inside the connecting tube. During the rotation, the cleaning liquid and the cleaning water can be fully mixed by an ultrasonic vibrator. Since the vortex is rotated around the connecting sleeve, the cleaning water can be better in contact with the vibration generated by the ultrasonic wave, and thus the cavitation reaction can be better carried out, avoiding the situation that the cleaning water cannot achieve a better cavitation reaction due to the short stay of the cleaning water. In addition, during the flow of water, multiple blades can be driven to mix the cleaning water and the cleaning liquid again, and then the mixed liquid is used to better clean the surface of the cleaning object by using multiple high-pressure spray heads, thereby reducing the process of personnel specifically mixing the cleaning water and the cleaning liquid, and improving the convenience of use.

[0021] When it is necessary to flush and clean the bogie and brake beam end of a railway freight car, the angle of the bellows can be adjusted according to its actual use so that its multiple high-pressure jet heads can perform better flushing and cleaning in a relatively narrow space. During flushing and cleaning, since the jet ports of the multiple high-pressure jet heads are all inclined in one direction, the connecting tube three can be rotated due to the action of the high-pressure water flow, thereby better expanding the area that can be cleaned and effectively improving its flexibility of use and cleaning efficiency.

[0030] See also Figure 1-4 , the utility model provides a technical solution:

[0031] The cavitation jet generating device and cleaning equipment include an ultrasonic vibrator 100 and a gripping rod 200, a connecting tube 210 is arranged on the top of the gripping rod 200, and an ultrasonic vibrating rod 220 electrically connected to the ultrasonic vibrator 100 is arranged on the side wall of the connecting tube 210;

[0032] In some embodiments: the ultrasonic generator 100 generally includes an oscillator, an oscillator amplifier and an ultrasonic vibration rod 220. The ultrasonic vibration rod 220 is also called an ultrasonic transducer. It is a device that converts electrical energy into mechanical vibrations. It is generally composed of piezoelectric ceramic sheets. When stimulated by high-frequency electrical signals, the piezoelectric ceramic sheets will generate mechanical vibrations, thereby generating ultrasonic waves. All of the above belong to the prior art.

[0033] The output end of the ultrasonic vibration rod 220 extends to the inside of the connecting tube 1 210 and is then sleeved with a connecting sleeve 230. The side wall of the connecting tube 1 210 is provided with a connecting tube 2 300. The end of the connecting tube 2 300 is connected to a bellows 310. The end of the bellows 310 is rotatably connected to a connecting tube 3 320. The internal threaded sealing connection of the connecting tube 3 320 is connected to a sealing tube 330.

[0034] Specifically, a water guide groove 240 is formed on the outer wall of the connecting sleeve 230 , and a rotation groove 250 is formed on the side wall of the connecting sleeve 230 , so as to facilitate the rotation connection of the rotating cylindrical block 260 .

[0035] Furthermore, a rotating cylindrical block 260 is rotatably connected inside the rotating groove 250, and a ball 261 is provided on the outer circumferential wall at the end of the rotating cylindrical block 260, which effectively reduces friction so that the water flow can better drive the blade 271 to rotate.

[0036] Furthermore, a connecting rod 270 is provided on the side wall of the rotating cylindrical block 260, and blades 271 are provided on the circumferential outer wall of the connecting rod 270 to facilitate better mixing of the cleaning water and the cleaning liquid.

[0037] Furthermore, a cleaning liquid inlet pipe 280 is provided at the top of the connecting cylinder 210, and a water inlet pipe 290 is provided on the front and rear circumferential outer walls of the connecting cylinder 210 to facilitate the injection of cleaning liquid and cleaning water.

[0038] It is worth noting that the water inlet pipe 290 and the multiple water inlet pipes 290 are often inclined in one direction after extending into the interior of the connecting tube 210 , so that the cleaning water can swirl inside the connecting tube 210 .

[0039] It is worth noting that the outer wall of the sealing cylinder 330 is provided with a high-pressure spray head 331, and the spray ports of the multiple high-pressure spray heads 331 are all inclined in one direction, which is convenient for driving the spray ports of the multiple high-pressure spray heads 331 to rotate, thereby expanding the cleaning area.

[0040] In addition, a conical water trough is provided inside the second connecting tube 300, and a bellows 310 is sealed and welded at the right end of the second connecting tube 300. The bellows 310 is made of stainless steel, so that the high-pressure spray head 331 can be used to flush and clean narrow and turning areas.

[0041] In addition, the cleaning device includes the aforementioned cavitation jet generating device.

[0042] In some embodiments: the device can be powered by an external conventional power source.

[0043] In addition, the circuits, electronic components and modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.

[0044] Working principle: First, when using it, you can use an external high-pressure water pump to let clean water enter from the water inlet pipe 290, and then use an external water pump to inject the cleaning liquid from the cleaning liquid inlet pipe 280. Since the multiple water inlet pipes 290 and the cleaning liquid inlet pipe 280 are extended to the inside of the connecting tube 210 and have a certain inclination, they can perform vortex rotation inside the connecting tube 210. During the rotation, the ultrasonic vibrator 220 can be used to fully mix the cleaning liquid and the clean water. Since it rotates under the vortex around the connecting sleeve, the clean water can better contact with the vibration generated by the ultrasonic wave, and then better perform the cavitation reaction, avoiding the situation where it is difficult to achieve a better cavitation reaction due to the short stay of the clean water, and in the process of water flow, it can drive multiple The blades 271 mix the cleaning water and the cleaning liquid again, and then use the mixed liquid to better clean the surface of the cleaning object using multiple high-pressure spray heads 331, thereby reducing the number of personnel who need to mix the cleaning water and the cleaning liquid, thereby improving the convenience of use. When it is necessary to flush and clean the bogie and the end shaft of the brake beam of a railway freight car, the angle of the bellows 310 can be adjusted according to its actual use, so that the multiple high-pressure spray heads 331 can better flush and clean in a relatively narrow space. During flushing and cleaning, since the spray ports of the multiple high-pressure spray heads 331 are all inclined in one direction, the high-pressure water flow can cause the connecting tube three 320 to rotate, thereby better expanding the area that can be cleaned, and effectively improving its flexibility of use and cleaning efficiency.
