A baffle 4 is fixedly connected around the area for placing the item to be flaw detected. One side of the baffle 4 is fixedly connected to a support 5, and the top end of the support 5 is fixedly connected to a sprayer 6. A fluorescent magnetization liquid chamber 7 is fixedly connected inside the preparation box 2. A water pump is fixedly connected to the inner bottom surface of the fluorescent magnetization liquid chamber 7. The water pump is connected to the sprayer 6 through a water pipe. Then, the fluorescent magnetization liquid in the fluorescent magnetization liquid chamber 7 can be automatically pumped into the sprayer 6 by the water pump and sprayed onto the item to be flaw detected below, improving the work efficiency. The collection groove 3 is located inside the flaw detector table 1. A liquid collection chamber 11 is fixedly connected to the inner bottom surface of the flaw detector table 1 directly below the collection groove 3. The liquid collection chamber 11 is connected to the collection groove 3 through a conduit. One side of the liquid collection chamber 11 close to the preparation box 2 is connected to an electric pump 12 through a conduit. The electric pump 12 is connected to the upper part of the fluorescent magnetization liquid chamber 7 through a hose. Then, the fluorescent magnetization liquid can be recycled to avoid waste.

[0017] A kerosene tank 13 is fixedly connected below the preparation box 2 inside the flaw detector table 1. One side of the kerosene tank 13 close to the side wall of the flaw detector table 1 is connected to a fuel filling pipe, which is convenient for adding the required kerosene. A cylinder 14 is fixedly connected to one side wall of the flaw detector table 1 close to the kerosene tank 13. The bottom end of the cylinder 14 is connected to the fluorescent magnetization liquid chamber 7 through a hose. The lower part of the cylinder 14 is connected to a connecting pipe 15. The other end of the connecting pipe 15 is connected to the kerosene tank 13. A one-way valve is fixedly connected to the connecting pipe 15 to prevent the liquid in the connecting pipe 15 from flowing back. A piston rod 16 is slidably connected to the top end of the cylinder 14. The top of the piston rod 16 is an L-shaped rod. The top end of the piston rod 16 is fixedly connected to a slider 17. A vertical chute 18 is opened on one side of the preparation box 2 close to the piston rod 16. The slider 17 is slidably connected to the outer surface of the chute 18. The top end of the piston rod 16 is slidably connected to the inner side wall of the chute 18. By moving the slider 17 up and down, a negative pressure is formed in the cylinder 14 to suck the kerosene in the kerosene tank 13 into the cylinder 14 and press it into the fluorescent magnetization liquid chamber 7. A scale is fixedly connected to the surface of the preparation box 2 on one side of the chute 18, which is convenient for controlling the amount of kerosene added.

[0020] When the utility model is in use, first, a certain amount of fluorescent magnetic powder is added to the fluorescent magnetic liquid chamber 7. Then, the slider 17 is pushed upward along the chute 18, driving the piston rod 16 to move upward, creating a negative pressure in the cylinder 14, opening the one-way valve, and allowing kerosene to flow from the kerosene tank 13 into the cylinder 14 through the connecting pipe 15. The slider 17 is pushed downward, and the piston at the bottom end of the piston rod 16 squeezes the kerosene, causing the kerosene to enter the fluorescent magnetic liquid chamber 7 through the hose. The water pump in the fluorescent magnetic liquid chamber 7 is started, and the fluorescent magnetic liquid is pumped through the water pipe into the sprayer 6 and sprayed onto the items to be flaw-detected below. The spraying operation of the device is automated, improving its working efficiency.

[0021] After the spraying operation is completed, the excess fluorescent magnetic liquid, under the guiding action of the baffle 4, all flows into the collection tank 3 and then into the liquid collection chamber 11 through the conduit. When the fluorescent magnetic liquid in the liquid collection chamber 11 reaches a certain amount, the electric pump 12 is started, and the electric pump 12 pumps the fluorescent magnetic liquid in the liquid collection chamber 11 into the fluorescent magnetic liquid chamber 7 through the hose to realize the recycling of the fluorescent magnetic liquid. By fixedly connecting a mobile trolley to the bottom of the device main body, the magnetic particle flaw detector can move so as to change the site at any time.
