Description

Technical Field

[0001] The present invention relates to the technical field of penetrant testing, and particularly to a portable on-site liquid extraction device for spray can type coloring or fluorescent penetrant. Background Art

[0002] Penetrant testing technology is a non-destructive testing technology based on the principle of capillary action, mainly used for detecting surface opening defects of non-porous metal or non-metal parts. During testing, a penetrant solution containing a fluorescent dye or a coloring dye is applied to the surface of the part. Due to capillary action, the penetrant seeps into the small surface opening defects. After removing the excess penetrant adhering to the surface of the workpiece, a developer is applied after drying. The penetrant in the defects is re-adsorbed onto the surface of the part under the action of capillary phenomenon, forming an enlarged defect display, and thus the morphology and distribution state of the defects can be detected.

[0003] Currently, spray can type penetrant testing is more suitable for on-site or field operations, that is, reagents such as cleaning agents, penetrants, and developers are filled into spray cans with compressed air. By pressing the pressure knob on-site, the ejection and use of the penetrant reagent can be realized. Therefore, most brands of penetrants are packaged in spray cans. However, for parts that must be subjected to penetrant testing using the brushing method, the penetrant needs to be placed in a small container on-site, and a brush is used to dip the penetrant and then brush it on the part to be inspected. This requires extracting the penetrant from the spray can type penetrant. Since the inside of the can is pressurized, a large amount of mist liquid will splash and diffuse during the liquid extraction process, causing great waste of the reagent and being easily inhaled by the operator, which also has an impact on physical health; at the same time, it requires the operator to press the nozzle with fingers for a long time, increasing the labor intensity of the personnel.

[0029] Embodiment 1

[0030] Refer to Figures 1 to 3, which is the first embodiment of the present invention, provides a portable on-site liquid extraction device for spray can type coloring or fluorescent penetrant. This device includes a pressing unit 100, which includes a holding member 101, a pressing member 102 arranged inside the holding member 101, a condensation member 103 inserted at one end outside the holding member 101, and a support spring 104 arranged between the pressing member 102 and the holding member 101. The holding member 101 is a member for holding the whole device, and its overall structure is an "L" shape with the opening downward. The overall structure of the pressing member 102 is similar to that of the holding member 101, and the condensation member 103 is in a quarter-ring structure and is connected to one end above the holding member 101; and,

[0031] A fixing unit 200, which includes a connecting member 201 fixedly connected to the lower part of the outer end of the holding member 101, three groups of clamping members 202 annularly distributed on the connecting member 201, an extrusion member 203 sleeved on the connecting member 201, and a spring ring 204 arranged inside the top ends of the three groups of clamping members 202. The connecting member 201 and the holding member 101 are fixedly connected, and the extrusion member 203 is threadedly rotatably connected to the connecting member 201. Since the three groups of clamping members 202 are distributed with the axis perpendicular to the connecting member 201 as the origin, the three groups of clamping members 202 and the connecting member 201 are in a sliding connection relationship in the horizontal direction.

[0032] Among them, a spray can type penetrant 300 is inserted into the connecting sleeve 201a. The spray can type penetrant 300 includes a can body 301 inserted into the connecting sleeve 201a, a nozzle 302 arranged at the top end of the can body 301, and the nozzle 302 extends into the bandage 103c. An auxiliary spray pipe 303 is arranged on the side of the nozzle 302, and the auxiliary spray pipe 303 extends into the connecting pipe 103a. The nozzle 302 and the auxiliary spray pipe 303 are existing mature technologies, and the reagent in the can body 301 can be discharged by pressing the nozzle 302.

[0033] During the use process, the top end of the can body 301 is inserted into the connecting member 201, so that the nozzle 302 at the top end of the can body 301 and the auxiliary spray pipe 303 are connected to the part of the condensation member 103 extending into the connecting member 201. Subsequently, by rotating the extrusion member 203, the three groups of clamping members 202 are driven to approach the axis position of the connecting member 201 synchronously, and then the can body 301 located below is clamped and fixed. Then, the holding member 101 is grasped and the pressing member 102 is squeezed. At this time, the part of the upper end of the pressing member 102 located inside the connecting member 201 will squeeze the nozzle 302, so that the liquid reagent in the can body 301 is discharged into the condensation member 103 through the auxiliary spray pipe 303, and then is condensed and collected by the condensation member 103, and finally is discharged from the end of the soy sauce condensation member 103 into a specified container, realizing the condensation and collection of the atomized reagent sprayed from the can body 301.

[0034] Example 2

[0035] Reference Figures 1 to 5 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it speeds up the collection efficiency of the atomized reagent and avoids the harm caused by the dispersion of the reagent to the human body.

[0036] Compared with Embodiment 1, further, the holding member 101 includes an annular connecting ring 101a, the condensation member 103 is inserted on one side of the connecting ring 101a, a grip 101b provided on the other side of the connecting ring 101a, and a relief groove 101c vertically opened on the inner side of the outer end of the grip 101b. The relief groove 101c is used to accommodate the space for the movement of the lever handle 102a, and the connecting ring 101a is fixedly connected to the grip 101b.

[0037] Among them, the pressing member 102 includes a lever handle 102a vertically located in the relief groove 101c, and the support spring 104 is provided between the lever handle 102a and the relief groove 101c. An arc-shaped lever 102b is provided at the top of the lever handle 102a and the end of the arc-shaped structure extends into the connecting ring 101a, and a pressing plate 102c is rotatably connected to the end of the arc-shaped lever 102b and covers the inner diameter of the connecting ring 101a.

[0038] Further, the lever handle 102a has a wave structure, which conforms to the ergonomic structure and is more comfortable to use. A rotating shaft is provided at the connection position between the arc-shaped lever 102b and the lever handle 102a, and the pressing member 102 can rotate as a whole around the rotating shaft. One end of the arc-shaped structure of the arc-shaped lever 102b is rotatably connected to the pressing plate 102c, and the diameter of the pressing plate 102c is the same as the inner diameter of the connecting ring 101a. Therefore, when the pressing plate 102c is pushed by the arc-shaped lever 102b, it can move vertically along the inner diameter of the connecting ring 101a.

[0039] During the use process, when the aerosol penetrant 300 is fixed in the fixing unit 200 and the nozzle 302 at the top is located directly below the pressing plate 102c, and the auxiliary spray pipe 303 is communicated with the condensation member 103, hold the lever handle 102a and the grip 101b with the hand at the same time. At this time, the lever handle 102a moves into the relief groove 101c and squeezes the relief groove 101c. The moving lever handle 102a will drive the arc-shaped lever 102b to rotate around the rotating shaft of the two. The rotating arc-shaped lever 102b will push the pressing plate 102c to squeeze the nozzle 302 in the connecting ring 101a, so that the reagent in the tank body 301 is discharged from the auxiliary spray pipe 303. Compared with the traditional method of pressing with fingers for a long time, squeezing and discharging the reagent by holding is more time-saving and labor-saving, and can effectively reduce the working intensity of the staff.

[0040] Among them, the condensation component 103 includes a connecting pipe 103a inserted into one side of the connecting ring 101a, a demisting pipe 103b connected to the outside of the connecting pipe 103a and extending into the connecting ring 101a, a bandage 103c arranged at the outer end of the demisting pipe 103b in a semi-circular ring structure, an inserting pipe 103d connected to the other end of the connecting pipe 103a and extending downward, a demister 103e arranged inside the connection position of the connecting pipe 103a and the inserting pipe 103d, and a discharge pipe 103f connected to the lower end of the inserting pipe 103d. The demisting pipe 103b is used to sleeve the auxiliary spray pipe 303 to ensure the communication between the spray can penetrant 300 and the condensation component 103. The bandage 103c is made of an elastic material and is used to strengthen the connection with the spray can penetrant 300. At the same time, the whole condensation component 103 opens downward for convenient collection.

[0041] Further, the demister 103e is composed of multiple groups of deflector plates 103e-1 arranged vertically. And in each adjacent two groups of deflector plates 103e-1, the deflector plate 103e-1 located below extends a slightly shorter distance towards the connecting pipe 103a. A demisting plate 103e-2 is vertically arranged at one end of each group of deflector plates 103e-1 extending outwards. Between every two adjacent demisting plates 103e-2, they are not only offset up and down, but also offset front and back. Therefore, there is a gap between them. The overall inclination direction of the deflector plates 103e-1 is inclined from the connecting pipe 103a towards the inserting pipe 103d from high to low.

[0042] During the use process, when the atomized reagent in the tank body 301 enters the connecting pipe 103a, under the pressure continuously sprayed by the tank body 301, the atomized reagent will first contact the demisting plate 103e-2. Multiple groups of deflector plates 103e-1 arranged vertically completely occupy the inner diameter channel of the demisting pipe 103b in the cross-section, and the offset demisting plates 103e-2 can increase the contact area with the atomized reagent in different dimensions, thereby increasing the condensation efficiency of the atomized reagent. Coupled with the arc-shaped channel of the demisting pipe 103b, it can effectively avoid the problem of the atomized reagent overflowing and causing harm to the human body, and accelerate the liquid condensation collection efficiency of the atomized reagent.

[0043] The remaining structures are the same as those in Embodiment 1.

[0044] Embodiment 3

[0045] Referring to Figures 2 to 6 , this is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the spray can penetrant 300 with different size specifications is clamped and fixed to improve the use flexibility of the device.

[0046] Compared with Embodiment 2, further, the connecting component 201 includes a connecting sleeve 201a fixedly connected below the connecting ring 101a, three groups of limiting sliding grooves 201b annularly formed on the connecting sleeve 201a, and three groups of clamping components 202 correspondingly arranged therein, and three groups of reset springs 201c correspondingly arranged below each group of limiting sliding grooves 201b and extending outwards. The connecting sleeve 201a is fixedly connected to the connecting ring 101a. The reset spring 201c always pulls the clamping component 202 towards the axial center position of the connecting sleeve 201a through its own elastic contraction.

[0047] Wherein, a thread groove is arranged on the outer side of the connecting sleeve 201a, and a thread protrusion matching therewith is arranged on the inner side of the pressing component 203. The inside of the connecting ring 101a and the connecting sleeve 201a communicate with each other. The pressing component 203 can displace in the vertical direction on the connecting sleeve 201a through threaded connection with the connecting sleeve 201a.

[0048] Wherein, the clamping component 202 includes a clamping block 202a located in the limiting sliding groove 201b, an arc-shaped clamping arm 202b arranged below the clamping block 202a and located inside the connecting sleeve 201a, and a resisting block 202c arranged below the outer side of the clamping block 202a. The outer end of the reset spring 201c is connected to the inner side of the resisting block 202c. The arc-shaped clamping arm 202b is a quarter-circular arc structure and can better fit on the cylindrical outer wall of the tank body 301.

[0049] Further, 204a has a right-angled triangle structure. Its longer right-angled side is parallel to the vertical direction of the inner wall of the connecting sleeve 201a. The outer side of the top end of the longest hypotenuse abuts against the bottom end surface of the pressing component 203. When the pressing component 203 moves downward in the vertical direction along the connecting sleeve 201a, it will squeeze the hypotenuse of the clamping block 202a, and then squeeze the clamping block 202a to make it move.

[0050] During the use process, the tank body 301 is inserted into the connecting sleeve 201a, and the pressing component 203 is rotated. The pressing component 203 moves downward along the connecting sleeve 201a, which will squeeze the hypotenuse of the clamping block 202a. Through the hypotenuse of the clamping block 202a, the downward pressure of the pressing component 203 can be converted into a force to push the clamping block 202a to move along the reset spring 201c towards the axial center position of the connecting sleeve 201a. The three groups of clamping components 202 are synchronously driven by the pressing component 203 to move, and the tank body 301 can be firmly installed and fixed. At the same time, the synchronous movement mode of the three groups of clamping components 202 can also play an alignment and centering function, ensuring that the aerosol penetrant 300 after being clamped and fixed is kept in a proper position, which is convenient for docking with the condensation component 103;

[0051] When the three groups of clamping components 202 move, they will squeeze the return spring 201c through the lower abutting block 202c, and squeeze the spring coil 204 through the inner side of the top end, so that both of them contract and store energy. When the pressing component 203 moves in the reverse direction and performs the release action, the spring coil 204 and the return spring 201c will simultaneously apply an outward thrust to the top end and the lower part of the clamping component 202, so that it is pushed outwards, thereby achieving the purpose of releasing the can body 301 and resetting the clamping component 202;

[0052] During this process, the clamping range of the three groups of clamping components 202 is controlled by the distance that the pressing component 203 moves on the connecting sleeve 201a. Therefore, according to different usage requirements, by adjusting the position of the pressing component 203 on the connecting sleeve 201a, it is possible to clamp and fix aerosol penetrants 300 of different sizes and specifications, with stronger usage flexibility.

[0053] The remaining structure is the same as that of Embodiment 2.
