Description

Technical Field

[0001] The utility model relates to a sprayer for detection, specifically to an improved wet magnetic particle detection sprayer. Background Art

[0002] In the use of wet magnetic particle detection, we usually use a sprayer to spray the magnetic suspension liquid. When inspecting, the inspector usually sprays the magnetic suspension liquid with one hand using the sprayer, and uses a magnetic yoke with the other hand for magnetic particle detection. Existing sprayers have the following deficiencies: First, the sprayer for filling the magnetic suspension liquid is heavy, and it needs to be manually shaken during use. The labor intensity is high during long-term detection, and the operation is extremely inconvenient; Second, the magnetic suspension liquid prepared by a conventional sprayer is easy to dissolve, and magnetic powder is easily adsorbed on the inner wall of the sprayer; Third, the conventional sprayer uses manual pressing to discharge the liquid, and the detection efficiency is very low, affecting the detection sensitivity. Content of the Utility Model

A motor is installed at the center position of the bottom end of the liquid storage cavity. The motor controls the rotation of a spiral stirrer. An electric pump is installed at the top end of the spiral stirrer. The top end of the electric pump is connected to a liquid outlet cavity. A signal processor is installed at the top end of the liquid outlet cavity. A pressure sensor is arranged inside the signal processor. After the pressure sensor adjusts and controls the pressure of the sprayed magnetic suspension liquid, the liquid outlet flow rate of the magnetic suspension liquid is controlled through a flow regulating valve and sprayed out from a spray pipe. The top end of the flow regulating valve is connected to the spray pipe. An liquid outlet controller and a light controller are arranged at the spraying end of the spray pipe;

[0005] The back surface of the kettle body is set as an arc surface. Straps are arranged on the left and right sides of the arc surface and fixedly connected to the kettle body; A scale surface is arranged on the front surface of the kettle body to observe the storage amount of the magnetic suspension liquid in the liquid outlet cavity; A liquid inlet is arranged at the upper part of one side surface of the kettle body, and a liquid drain port is arranged below the liquid inlet. A detachable pressure cover is installed at the top end of the kettle body to completely seal the sprayer and maintain the pressure inside the kettle. A hole is arranged on the pressure cover through the spray pipe.

[0006] As a preferred embodiment of the utility model, a liquid suction pipe is arranged inside the through spiral stirrer and communicated with the bottom end of the motor. The liquid suction pipe evenly and stably transports the magnetic suspension liquid to the liquid outlet cavity through the electric pump and then sprays it out. Blades are installed on the spiral stirrer for evenly stirring the magnetic suspension liquid with large torque.

[0007] As a preferred embodiment of the present utility model, a liquid outlet is provided at the ejection port of the nozzle. Black light lamps and flashlights are installed on both sides of the liquid outlet for observing magnetic traces. The black light lamps and flashlights are controlled by a lighting controller.

[0008] As a preferred embodiment of the present utility model, the kettle body is made of polyvinyl chloride non-magnetic plastic to reduce the deposition of magnetic powder.

[0009] The present utility model has the following beneficial effects compared with the prior art:

[0010] By adopting a shoulder strap, the present utility model increases the usage methods of the spray kettle and is convenient for inspectors to carry. By adopting a motor and a spiral stirrer to uniformly mix the magnetic suspension liquid, the uniformity of the magnetic suspension liquid is improved, the problem of uneven concentration is avoided, and the work intensity of inspectors is greatly reduced. The liquid outlet control switch and the signal processor control the liquid outlet, which can ensure the stability of the liquid outlet pressure and flow rate, thereby improving the adhesion of the magnetic suspension liquid on the workpiece surface and further improving the detection efficiency. By installing a black light lamp or a flashlight at the spray port end, the magnetic traces can be observed more conveniently, thereby improving the accuracy and efficiency of defect identification.

The top end of the flow regulating valve 7 is connected to the spray pipe 21. An outlet liquid controller 18 and a lighting controller 19 are arranged at the spraying end of the spray pipe 21. The back surface of the kettle body 1 is set as an arc surface 2. Straps 23 are arranged on the left and right sides of the arc surface 2 and are fixedly connected to the kettle body 1. A scale surface 22 is arranged on the front surface of the kettle body 1 to observe the storage amount of the magnetic suspension liquid in the liquid outlet cavity 20.

A detachable pressure cover 13 is installed at the top end of the kettle body 1 to completely seal the sprayer and maintain the internal pressure of the kettle. The pressure cover 13 is provided with a hole through the spray pipe 21.

[0019] In this setting, the design of the arc surface 2 on the back surface of the kettle body 1 conforms to the amplitude of the human back. The sprayer can be placed on the ground for use or can be used in combination with the straps 23, which is convenient for long-term carrying and use, reduces the working intensity of personnel, increases the usage methods of the sprayer, and a motor 3 is arranged in the liquid storage cavity 12 to drive the spiral stirrer 4 to drive the blades to rotate to achieve a stirring effect of low speed and high torque, which can ensure the uniformity of the magnetic suspension liquid.

[0020] As Figures 1 to 3 shown, a liquid suction pipe 10 is arranged inside the through spiral stirrer 4 and is communicated with the bottom end of the motor 3. The liquid suction pipe 10 uniformly and stably transports the magnetic suspension liquid to the liquid outlet cavity 20 through the electric pump 5 and then sprays it out. Blades 16 are installed on the spiral stirrer 4 for uniformly stirring the magnetic suspension liquid with high torque.

[0021] In this setting, when using the liquid outlet controller 18, manual pressing of the liquid outlet controller 18 can conduct to the pressure sensor 6, and the signal processor 11 processes the information.
