Description

Technical Field

[0001] The utility model relates to a water circulation flushing system of an ultrasonic flaw detector, belonging to the technical field of flaw detectors. Background Art

[0002] At present, in the manufacturing process of steel pipes, due to problems such as slag inclusions or loose materials in the raw materials, cracks, sand holes and other defects will occur after the steel pipes are formed. In order to ensure the quality of steel pipe products and reduce safety hazards during use, ultrasonic flaw detection equipment is needed to detect steel pipes. Nowadays, the efficiency of ultrasonic flaw detection equipment is constantly increasing due to the increase in the number of channels, but the high speed causes dirt to adhere to the flaw detection and thickness measurement probes, resulting in frequent misses in ultrasonic detection. Operators need to clean the probes several times per hour, which is time-consuming and labor-intensive, greatly restricting the production rhythm of the production line. There is no circulating filtration device for the water used for ultrasonic detection. Personnel need to be arranged regularly every week to clean the water tank, empty the sewage in the water tank, and flush it with a large amount of water, which is time-consuming and labor-intensive, and wastes a lot of water resources.

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The steel pipe ultrasonic flaw detection water circulation flushing system of the utility model is further described below in conjunction with the accompanying drawings.

[0014] Figure 1 It is a structural schematic diagram of an embodiment of the utility model.

[0015] The above-mentioned reference numerals are as follows:

[0016] Ultrasonic flaw detection host 1, steel pipe conveying roller table 2, partition plate 3, filter press 4, pipe flushing water tank 5, water receiving tray 6, high-pressure nozzle 7, clean water tank 8, sewage tank 9, pneumatic diaphragm pump 10. DETAILED DESCRIPTION Example 1

[0017] See Figure 1The steel pipe ultrasonic flaw detection water circulation flushing system of this embodiment includes an ultrasonic flaw detection host 1, a steel pipe conveying roller 2, a filter press 4, a pipe flushing water tank 5, a water receiving tray 6, a high-pressure nozzle 7, a clean water tank 8 and a sewage tank 9. The ultrasonic flaw detection host 1 and the high-pressure nozzle 7 are arranged above the steel pipe conveying roller 2, the high-pressure nozzle 7 is located in front of the ultrasonic flaw detection host 1, and the water receiving tray 6 is located directly below the high-pressure nozzle 7. The water inlet of the ultrasonic flaw detection host 1 is connected to the clean water tank 8, the water inlet of the filter press 4 is connected to the sewage tank 9, and the filter press 4 is provided with two water outlets, one of which is connected to the clean water tank 8 and the other is connected to the pipe flushing water tank 5. The water outlet of the pipe flushing water tank 5 is connected to the high-pressure nozzle 7, and the water receiving tray 6 is connected to the sewage tank 9. The water flow in the circulation system first passes through the sewage tank 9 and then passes through the filter press 4. The two water outlets of the filter press 4 go to the pipe flushing water tank 5 and the clean water tank 8 respectively. The water in the clean water tank 8 flows to the ultrasonic flaw detection host 1, and sprays the steel pipe when the ultrasonic flaw detection host 1 is working. The water in the pipe flushing water tank 5 flows to the high-pressure nozzle 7 to pre-wash the steel pipe on the steel pipe conveying roller 2, and then is collected by the water receiving tray 6 and returned to the sewage tank 9.

[0018] The filter press 4 is located higher than the sewage pool 9 . A pneumatic diaphragm pump 10 is provided on the pipeline between the sewage pool 9 and the filter press 4 . The sewage is injected into the filter press 4 through the pneumatic diaphragm pump 10 .

[0019] A water level controller for controlling the operation of the pneumatic diaphragm pump 10 is provided inside the sewage pool 9. The water level controller is used to realize the liquid level difference and thus control the working time of the diaphragm pump 10. After long-term use, it is found that the water output of the filter press 4 will decrease with the increase of the amount of dirt attached to the surface of the filter cloth. When the frequency of the diaphragm pump 20 is constant, it means that the water level of the sewage pool 9 and the water level of the clean water pool 8 cannot be controlled. A water level controller is added to realize the liquid level difference to control the working time of the diaphragm pump 10, thereby achieving equal liquid level.

[0020] A float valve is provided inside the pipe flushing water tank 5 , and the float valve can control the water inlet of the pipe flushing water tank 5 . The water inlet is controlled by the float valve, and the flushing sewage circulates into the sewage pool 9 .

[0021] The clean water tank 8 and the sewage tank 9 are located in the same water tank, and a partition plate 3 is provided in the water tank to separate the clean water tank 8 and the sewage tank 9, so that the water flows of the sewage tank 9 and the clean water tank 8 do not flow to each other, thereby greatly increasing the clean water storage capacity.

[0022] The filter press 4 is provided with a filter cloth for blocking dirt inside, and the entire circulating water system is closed, which reduces the pollution of sodium nitrite in the wastewater, saves water for ultra-exploration, and only needs to add a small amount of water regularly, thereby improving work efficiency.

[0023] The steel pipe ultrasonic flaw detection water circulation flushing system of this embodiment also includes an annular fixing seat fixedly connected to the top of the steel pipe conveying roller 2, and a plurality of high-pressure nozzles 7 are arranged at intervals along the inner wall of the annular fixing seat. The high-pressure nozzles 7 are all directed toward the center of the annular fixing seat.

[0024] In the steel pipe ultrasonic flaw detection water circulation flushing system of this embodiment, when in use, the steel pipe conveying roller 2 conveys the steel pipe to the high-pressure nozzle 7 for pre-cleaning, and then conveys it to the ultrasonic flaw detection host 1 for flaw detection. The sewage of the ultrasonic flaw detection host 1 is conveyed to the sewage pool 9 through a pipeline, and the sewage is injected into the filter press 4 through the pneumatic diaphragm pump 10. The filter cloth in the filter press 4 filters the sewage, and part of the filtered clean water flows back to the clean water pool 8 through the pipeline elevation difference, and the other part of the clean water is conveyed to the pipe flushing water tank 5. The clean water for pre-cleaning of the high-pressure nozzle 7 is provided by the flushing water tank 5, and the water receiving tray 6 located directly below the high-pressure nozzle 7 recycles the pre-cleaned water and conveys it to the sewage pool 9, thereby forming a closed water circulation system.

[0025] Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
