A main sleeve is rotatably arranged on the upper end surface of the dispensing tank, and a secondary sleeve is rotatably arranged and penetrates through the inside of the main sleeve. A flow dividing cylinder penetrates through the top wall of the secondary sleeve. A rotating assembly is arranged between the top of the dispensing tank and the main sleeve and the secondary sleeve. A mixing and turbulence ring plate is arranged in the middle inside the dispensing tank. An upper liquid spraying box and a lower liquid spraying box are symmetrically arranged on the outer sides of the main sleeve and the secondary sleeve respectively. With the assistance of the obliquely arranged second conduit, first conduit and slow-down inclined plate, it is avoided that the upper and lower fluorescent magnetic suspension liquids conveyed by the power pump and the dispensing pump collide violently inside the outer mixing ring box. The fluorescent magnetic suspension liquid will be obliquely ejected through the diversion cavity and the drain hole end in sequence and intersect and mix with the fluorescent magnetic suspension liquid with a rotational movement trend, so that while the fluorescent magnetic suspension liquid is gently mixed in the dispensing tank, it also has a good dispensing effect.

Description

Technical Field

[0001] The present invention belongs to the technical field of flaw detection magnetic suspension liquid mixing equipment, and particularly relates to a flaw detection magnetic suspension liquid mixing and preparation system. Background Art

[0002] A suspension liquid formed by mixing magnetic powder for flaw detection and a dispersant composed of water or oil in a certain proportion is called a magnetic suspension liquid. Fluorescent magnetic powder is made with magnetic iron oxide powder, industrial pure iron powder, carbonyl iron powder, etc. as the core and coated with a layer of fluorescent dye on the outside. Generally, a fluorescent dye that shows yellow-green fluorescence under ultraviolet light excitation is selected. Within a certain range, the luminous intensity is proportional to the ultraviolet radiation intensity.

[0003] For example, a Chinese patent with the publication number CN108905880A discloses a suspension liquid mixing and preparation system. The suspension liquid mixing and preparation system includes: a preparation tank, a jet injector, an annular disc jet system, a liquid inlet pipe, a power pump, a preparation pipe, a preparation pump, and a dosing machine; the jet injector and the annular disc jet system are both arranged in the preparation tank; the liquid inlet pipe connects the inlet of the power pump with the bottom of the inner cavity of the preparation tank, and the preparation pipe connects the inlet of the preparation pump with the upper part of the inner cavity of the preparation tank; the outlet of the power pump is connected to the jet injector, the outlet of the preparation pump is connected to the jet injector and is also connected to the annular disc jet system; the dosing machine is connected to the preparation pipe; two liquid inlet ports are arranged on the mixing cavity, and the two liquid inlet ports are respectively connected to the outlet of the power pump and the outlet of the preparation pump; the two major stirring systems of the jet injector and the annular disc jet system are used to mix and stir the liquid layers in the preparation tank, increasing the stirring service radius, improving the stirring efficiency, and having no dead angle during the stirring process.

[0004] However, the above solution has the following deficiencies: In the above solution, the upper and lower magnetic suspension liquids will be discharged into the mixing cavity in the jet injector through the outlets of the power pump and the preparation pump respectively for mixing in a mutually perpendicular jetting manner. The mutually perpendicular jetting magnetic suspension liquids will have high-speed and intense cross collisions. For fluorescent magnetic powder, the bonding strength between the fluorescent powder and the magnetic powder on it is affected by the mixing collision intensity, temperature, and solution pH value of the external environment. From an economic perspective, the fluorescent magnetic suspension liquid used in a magnetic particle flaw detector will be reused within a limited period. When the fluorescent magnetic powders are subjected to intense collisions due to external environmental factors, due to the large collision intensity, part of the fluorescent powder and the magnetic powder will fall off, making the magnetic powder wrapped with a fluorescent layer appear dim under specific light, affecting the imaging effect of the fluorescent magnetic suspension liquid at the crack of the workpiece, being unfavorable for flaw detection, and shortening the service life of the fluorescent magnetic suspension liquid at the same time. How to make the fluorescent magnetic suspension liquid be gently mixed in the preparation tank while having a good preparation effect is a problem that needs to be solved currently.

[0005] To this end, we propose a flaw detection magnetic suspension liquid mixing and dispensing system to solve the problems mentioned in the above background technology. Summary of the Invention

[0009] A rotating assembly is arranged between the top of the dispensing tank and the main sleeve and the secondary sleeve, and the rotating assembly is arranged so that the main sleeve and the secondary sleeve rotate in opposite directions;

[0010] A mixing and turbulence ring plate is horizontally arranged in the middle inside the dispensing tank, the lower part of the secondary sleeve penetrates through the central hole of the mixing and turbulence ring plate, an outer mixing ring box communicated with the mixing and turbulence ring plate is annularly sleeved outside the dispensing tank, and the liquid outlet side of the power pump is also communicated with the outer mixing ring box;

[0011] Upper liquid spraying boxes and lower liquid spraying boxes are symmetrically arranged on the outer sides of the main sleeve and the secondary sleeve respectively, and the upper liquid spraying boxes and the lower liquid spraying boxes are respectively located above and below the mixing and turbulence ring plate and are arranged oppositely. When the rotating assembly drives the main sleeve and the secondary sleeve to rotate, the upper liquid spraying boxes and the lower liquid spraying boxes are driven to rotate in opposite directions in turn. The magnetic suspension liquid preliminarily mixed through the outer mixing ring box and discharged through the upper and lower end faces of the mixing and turbulence ring plate is fully and gently mixed with the magnetic suspension liquid discharged from the upper liquid spraying boxes and the lower liquid spraying boxes respectively.

[0012] Preferably, the lower liquid guide pipe and the liquid outlet side of the upper liquid guide pipe are respectively communicated with the side wall and the top wall of the shunt pipe head. A stepped drainage pipe is vertically arranged inside the shunt pipe head. The bottom of the stepped drainage pipe is rotatably arranged and penetrates through a preset sealing bearing hole in the bottom end surface of the inner wall of the shunt cylinder. The liquid outlet side of the upper liquid guide pipe is communicated with the stepped drainage pipe. A funnel block is arranged at the lower part inside the auxiliary sleeve. The magnetic suspension liquid discharged from the stepped drainage pipe converges through the funnel block and then is discharged into the two lower liquid spraying boxes on both sides.

[0013] Preferably, the side where the lower liquid guide pipe is communicated with the shunt pipe head is arranged below the stepped part of the stepped drainage pipe. And the magnetic suspension liquid discharged into the shunt pipe head through the lower liquid guide pipe sequentially passes through the shunt cylinder, the connecting pipe and the main sleeve and is sprayed out from the upper liquid spraying box end.

[0014] Preferably, the rotating assembly includes a driving motor fixedly arranged on the top of the dispensing tank. A gear set and a belt set are sequentially sleeved on the output shaft end of the driving motor. The gear set includes a driving gear and a driven gear. The driving gear and the driven gear are respectively sleeved on the output shaft end of the driving motor and the outer side part of the main sleeve. The belt set includes a driving belt pulley and a driven belt pulley. The driving belt pulley and the driven belt pulley are respectively sleeved on the output shaft end of the driving motor and the outer side part of the auxiliary sleeve. And a belt drive is sleeved between the driving belt pulley and the driven belt pulley. The rotation directions of the driven gear and the driven belt pulley on the main sleeve and the auxiliary sleeve are opposite.

[0015] Preferably, the dispensing pump is communicated with the outer mixing ring box. The upper and lower end faces of the mixing and turbulence-removing ring plate are both of a funnel-shaped structure. And a diversion cavity is circumferentially arranged on the outer side wall of the mixing and turbulence-removing ring plate. The diversion cavity is communicated with the corresponding outer mixing ring box. Drainage holes are obliquely arranged on the upper and lower end faces of the inner wall of the diversion cavity. The liquid outlet side of the power pump is connected with the two first conduits on both sides through a four-way valve. The two first conduits on both sides are respectively connected with the two sides of the bottom end face of the outer mixing ring box in an inclined state.

A second conduit is obliquely connected between the liquid outlet side of the dispensing pump and the side wall of the outer mixing ring box. And a slow-down inclined plate is arranged below the liquid outlet side of the second conduit inside the outer mixing ring box. The magnetic suspension liquid discharged into the outer mixing ring box through the obliquely arranged second conduit is adjusted in the flow direction by the slow-down inclined plate and is arranged to have the same circumferential flow direction as the magnetic suspension liquid discharged through the first conduit.

[0016] Preferably, at least two turning diversion channels are arranged inside both the upper liquid spraying box and the lower liquid spraying box. The liquid outlet side of the turning diversion channel faces the mixing and turbulence-removing ring plate. Stirring pipes are communicated with the front and rear end faces of the upper liquid spraying box and the lower liquid spraying box. Spraying holes are arranged on the outer side wall of the stirring pipe.

[0017] Preferably, reset spring sleeve rod frames are arranged on the opposite surfaces of the upper liquid spraying box and the lower liquid spraying box. An adapter hole plate is slidably sleeved on the spring end of the reset spring sleeve rod frame. Adjusting plugs are arranged on both sides of the adapter hole plate. The adjusting plugs are movably inserted into the side of the liquid outlet of the steering diversion channel. When the rotating assembly does not rotate, the adjusting plugs block the steering diversion channel under the action of the reset spring sleeve rod frame. When the rotating assembly indirectly drives the rotation speeds of the upper liquid spraying box and the lower liquid spraying box to gradually increase, the opening gap between the adjusting plugs and the steering diversion channel gradually increases.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: With the assistance of the obliquely arranged second conduit, first conduit, and slow-speed inclined plate, violent collision between the upper and lower fluorescent magnetic suspensions transported by the power pump and the dispensing pump inside the outer mixing ring box is avoided. The fluorescent magnetic suspension flowing into the outer mixing ring box for preliminary mixing will successively pass through the diversion cavity and the drain hole end and be obliquely ejected, and intersect and mix with the fluorescent magnetic suspension with a rotating motion tendency generated by the rotation states of the upper liquid spraying box and the lower liquid spraying box. The stirring tube can assist in stirring and mixing the upper and lower fluorescent magnetic suspensions that intersect and mix, avoiding the mixing method of violent collision between the fluorescent magnetic suspensions, enabling the fluorescent magnetic suspension to be gently mixed inside the dispensing tank while having a good dispensing effect.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figures 1-7 , the present invention provides a technical solution:

[0029] Embodiment 1:

[0030] A flaw detection magnetic suspension liquid mixing and dispensing system, including a dispensing tank 1, a power pump 2 and a dispensing pump 3 respectively connected and arranged at its bottom and side. The bottom of the dispensing tank 1 is anchored to the ground by a base (not shown) for stable placement. Both the power pump 2 and the dispensing pump 3 are water pumps. The liquid inlet side of the power pump 2 is connected to the bottom of the dispensing tank 1. A dosing machine 4 is arranged on the liquid inlet side of the dispensing pump 3. The dosing machine 4 is a metering pump and dosing pump produced by Shanghai Longya Pump Valve Manufacturing Co., Ltd. JM15 / 10. The model and specification of the dosing machine 4 are adaptively adjusted according to the volume of the dispensing tank 1. A first sealed bearing hole is preset at the central axis position of the inner top wall of the dispensing tank 1. A main sleeve 5 is rotatably arranged and inserted vertically through the first sealed bearing hole at the central axis position of the upper end face of the dispensing tank 1. And auxiliary sealing can be carried out by smearing 2 mm thick sealing grease outside the above first sealed bearing hole. The following sealed bearing holes are assisted in sealing in the same way. The main sleeve 5 can rotate relative to the dispensing tank 1. The upper and lower end faces of the main sleeve 5 are of a closed design. And second sealed bearing holes are preset at the upper and lower end faces inside the main sleeve 5. A secondary sleeve 6 is rotatably arranged and penetrates through the upper and lower end faces at the central axis position inside the main sleeve 5 through the second sealed bearing holes. The secondary sleeve 6 can rotate relative to the main sleeve 5. A flow dividing cylinder 7 is fixedly penetrated vertically through the top wall of the secondary sleeve 6. The flow dividing cylinder 7 rotates in the same direction as the secondary sleeve 6. Four connecting pipes 8 are circumferentially connected and communicated between the side wall of the flow dividing cylinder 7 and the outer wall of the secondary sleeve 6 and are communicated with the main sleeve 5. A third sealed bearing hole is preset on the top wall of the flow dividing cylinder 7. A flow dividing pipe head 9 is rotatably arranged and inserted vertically through the third sealed bearing hole on the top wall of the flow dividing cylinder 7. The flow dividing pipe head 9 can rotate relative to the flow dividing cylinder 7. The liquid outlet sides of the power pump 2 and the dispensing pump 3 are respectively provided with a lower liquid guiding pipe 10 and an upper liquid guiding pipe 11 and are communicated with the flow dividing pipe head 9. The flow dividing pipe head 9 introduces the lower liquid guiding pipe 10 and the upper liquid guiding pipe 11 into the liquid inlet side of the connecting pipe 8 and the inside of the secondary sleeve 6 below the flow dividing cylinder 7 respectively;

[0031] A rotating assembly is arranged between the top of the dispensing tank 1 and the main sleeve 5 and the secondary sleeve 6, and the rotating assembly is arranged so that the rotation directions of the main sleeve 5 and the secondary sleeve 6 are opposite;

[0032] A mixing and turbulence ring plate 12 is horizontally arranged in the middle of the inner side of the dispensing tank 1. The fluorescent magnetic suspension liquid ejected through the mixing and turbulence ring plate 12 is in a slow state. The lower part of the secondary sleeve 6 penetrates through the middle hole of the mixing and turbulence ring plate 12. An outer mixing ring box 13 connected to the mixing and turbulence ring plate 12 is annularly sleeved outside the dispensing tank 1. The liquid outlet sides of the power pump 2 and the dispensing pump 3 are also communicated with the outer mixing ring box 13;

[0033] On the outer sides of the main sleeve 5 and the auxiliary sleeve 6, an upper liquid spraying box 14 and a lower liquid spraying box 15 are symmetrically arranged respectively. The upper liquid spraying box 14 and the lower liquid spraying box 15 are located above and below the mixing and turbulence ring plate 12 respectively and are arranged oppositely. When the rotating assembly drives the main sleeve 5 and the auxiliary sleeve 6 to rotate, the rotating speed is controlled at a stirring speed of 80 - 150 r / min, which drives the upper liquid spraying box 14 and the lower liquid spraying box 15 to rotate in opposite directions successively. The magnetic suspension liquid is preliminarily mixed by the outer mixing ring box 13 and the magnetic suspension liquid discharged through the upper and lower end faces of the mixing and turbulence ring plate 12 is fully and gently mixed with the magnetic suspension liquid discharged from the upper liquid spraying box 14 and the lower liquid spraying box 15 respectively. Since the discharged magnetic suspension liquid is in a rotating state, there will be no large collision between the fluorescent magnetic suspension liquids. The mixing and turbulence ring plate 12 divides the inner part of the dispensing tank 1 into upper and lower two spaces. At the same time, the upper liquid spraying box 14 and the lower liquid spraying box 15 are arranged with opposite rotating directions, so that the rotating directions of the fluorescent magnetic suspension liquids above and below the mixing and turbulence ring plate 12 are different. The fluorescent magnetic suspension liquids in the upper and lower two spaces will converge and mix at the central hole part of the mixing and turbulence ring plate 12, having a good mixing effect.

[0034] Embodiment 2:

[0035] On the basis of Embodiment 1, it is further described that the liquid outlet sides of the lower liquid guiding pipe 10 and the upper liquid guiding pipe 11 are respectively connected and communicated with the side wall and the top wall of the shunt pipe head 9. A stepped drainage pipe 16 is arranged vertically inside the shunt pipe head 9. A fourth sealed bearing hole is preset on the bottom end face inside the shunt cylinder 7. The bottom of the stepped drainage pipe 16 is rotatably arranged and penetrates through the preset fourth sealed bearing hole on the bottom end face of the inner wall of the shunt cylinder 7, so that relative rotation is enabled between the stepped drainage pipe 16 and the bottom of the shunt cylinder 7. At the same time, both the upper and lower end faces of the stepped drainage pipe 16 are designed to be open. There is a 3CM gap between the outer surface of the stepped drainage pipe 16 and the inner wall of the shunt pipe head 9. The liquid outlet side of the upper liquid guiding pipe 11 is connected and communicated with the stepped drainage pipe 16. A funnel block 17 is arranged at the lower part inside the auxiliary sleeve 6. The magnetic suspension liquid discharged from the stepped drainage pipe 16 converges through the funnel block 17 and then is discharged into the lower liquid spraying boxes 15 on both sides, playing a good role in draining the fluorescent magnetic suspension liquid;

[0036] The connection side of the lower liquid guiding pipe 10 and the shunt pipe head 9 is arranged below the stepped part of the stepped drainage pipe 16, and the magnetic suspension liquid discharged into the shunt pipe head 9 from the lower liquid guiding pipe 10 passes through the shunt cylinder 7, the connecting pipe 8 and the main sleeve 5 in sequence and is sprayed out from the upper liquid spraying box 14 end.

[0037] Embodiment 3:

[0038] On the basis of the first embodiment, further explanation is as follows. The rotating assembly includes a drive motor 18 fixedly arranged on the top of the dispensing tank 1. The drive motor 18 is a servo motor. A gear set 19 and a belt set 20 are sequentially sleeved on the output shaft end of the drive motor 18. The gear set 19 includes a driving gear and a driven gear. The driving gear and the driven gear are respectively sleeved on the output shaft end of the drive motor 18 and the outer side of the main sleeve 5. The belt set 20 includes a driving pulley and a driven pulley. The driving pulley and the driven pulley are respectively sleeved on the output shaft end of the drive motor 18 and the outer side of the auxiliary sleeve 6. And a belt drive is sleeved between the driving pulley and the driven pulley. The rotating directions of the driven gear and the driven pulley on the main sleeve 5 and the auxiliary sleeve 6 are set to be opposite. By changing the specifications and sizes of the driven gear and the driven pulley, the rotation speeds of the main sleeve 5 and the auxiliary sleeve 6 can be adjusted respectively.

[0039] Embodiment Four:

[0040] On the basis of the first embodiment, further explanation is as follows. Both the upper and lower end faces of the mixing turbulence ring plate 12 are funnel-shaped structures with smooth surfaces. And a diversion cavity 21 is circumferentially arranged on the outer side wall of the mixing turbulence ring plate 12. The diversion cavity 21 is communicated with the corresponding outer mixing ring box 13. Drainage holes 22 are obliquely arranged on both the upper and lower end faces of the inner wall of the diversion cavity 21. The drainage holes 22 are obliquely arranged towards the direction of the auxiliary sleeve 6. The liquid outlet side of the power pump 2 is connected to both sides of the first conduit 23 through a four-way valve. The two first conduits 23 are respectively connected to both sides of the bottom end face of the outer mixing ring box 13 in an inclined state. The inclined directions of the two first conduits 23 and both sides of the bottom end face of the outer mixing ring box 13 are opposite. The first conduit 23 in the inclined connection state enables the magnetic suspension liquid discharged into the outer mixing ring box 13 to flow circumferentially. The liquid outlet side of the dispensing pump 3 is obliquely communicated with the side wall of the outer mixing ring box 13 through a three-way valve and is provided with a second conduit 24. And a slow-down inclined plate 25 is arranged below the liquid outlet side of the second conduit 24 inside the outer mixing ring box 13. The magnetic suspension liquid discharged into the outer mixing ring box 13 through the obliquely arranged second conduit 24 is adjusted in the flow direction by the slow-down inclined plate 25 and is set to be the same as the circumferential flow direction of the magnetic suspension liquid discharged by the first conduit 23. It can enable the fluorescent magnetic suspension liquid discharged by the second conduit 24 to gently blend into the fluorescent magnetic suspension liquid discharged by the first conduit 23, avoiding violent collision of the fluorescent magnetic suspension liquid discharged by the first conduit 23 and the second conduit 24.

[0041] Embodiment Five:

[0042] On the basis of the first embodiment, it is further explained that there are two steering diversion channels 26 provided inside both the upper liquid spraying box 14 and the lower liquid spraying box 15. The liquid outlet side of the steering diversion channel 26 faces the mixing and turbulence ring plate 12. The steering diversion channel 26 is of an L-shaped structure. Except for the outermost steering diversion channel 26 in the upper liquid spraying box 14 or the lower liquid spraying box 15, water diversion holes are provided on the inner side wall of the inner steering diversion channel 26 for the flow of the fluorescent magnetic suspension liquid between adjacent steering diversion channels 26. Stirring pipes 27 are connected and arranged on the front and rear end faces of the upper liquid spraying box 14 and the lower liquid spraying box 15. Spraying holes 28 are arranged on the outer side wall of the stirring pipe 27. While the stirring pipe 27 can spray the fluorescent magnetic suspension liquid, it can also assist in stirring the fluorescent magnetic suspension liquid inside the dispensing tank 1.

[0043] Reset spring sleeve rod frames 29 are arranged on the opposite surfaces of the upper liquid spraying box 14 and the lower liquid spraying box 15. A connecting hole plate 30 is slidably sleeved on the spring end of the reset spring sleeve rod frame 29. Connecting holes are symmetrically arranged on the upper end face of the connecting hole plate 30. Adjusting plug blocks 31 are arranged on both sides of the connecting hole plate 30. The adjusting plug block 31 is of a frustum-shaped structure. The adjusting plug block 31 is movably inserted into the liquid outlet side of the steering diversion channel 26. When the rotating assembly does not rotate, the adjusting plug block 31 blocks the steering diversion channel 26 under the action of the reset spring sleeve rod frame 29. When the rotating assembly indirectly drives the rotation speeds of the upper liquid spraying box 14 and the lower liquid spraying box 15 to gradually increase, the opening gap between the adjusting plug block 31 and the steering diversion channel 26 gradually increases, so as to adaptively adjust the flow rate of the fluorescent magnetic suspension liquid sprayed from the steering diversion channel 26.

[0044] The working principle is as follows: Connect the power supply ends of the power pump 2, the dispensing pump 3, the chemical feeder 4, and the drive motor 18 to an external power supply and control them through an external control cabinet. When the volume concentration of the magnetic suspension liquid is <0.2 ml / 100 ml, add an appropriate amount of fluorescent magnetic powder; when the volume concentration of the magnetic suspension liquid is >0.6 ml / 100 ml, add an appropriate amount of water, and regulate the opening and closing of the chemical feeder 4. When performing the mixing process inside the dispensing tank 1, adjust the rotation speed of the output shaft end of the drive motor 18 through the external control cabinet. The output shaft end of the drive motor 18 drives the main sleeve 5 and the auxiliary sleeve 6 to rotate respectively through the gear set 19 and the belt set 20 in sequence. The main sleeve 5 and the auxiliary sleeve 6 respectively make the lower liquid spraying box 15 and the upper liquid spraying box 14 rotate in the opposite direction with the assistance of the stirring pipe 27. The adjusting plug 31 overcomes the reset spring sleeve rod holder 29 under the action of the rotational centrifugal force of the upper liquid spraying box 14 or the lower liquid spraying box 15 and separates from the liquid outlet side of the steering diversion channel 26. When the power pump 2 works, it can discharge the fluorescent magnetic suspension liquid at the lower part of the dispensing tank 1 into the upper liquid spraying box 14 and the outer mixing ring box 13 respectively through the lower liquid guide pipe 10 and the first conduit 23. The fluorescent magnetic suspension liquid in the outer mixing ring box 13 performs a circumferential movement, while the dispensing pump 3 discharges the fluorescent magnetic suspension liquid at the center of the mixing turbulence ring plate 12 into the right inner part of the lower liquid spraying box 15 and the outer mixing ring box 13 respectively. With the assistance of the inclined second conduit 24, the first conduit 23, and the slow-speed inclined plate 25, violent collision between the lower and upper fluorescent magnetic suspension liquids transported by the power pump 2 and the dispensing pump 3 is avoided;

[0045] The lower fluorescent magnetic suspension liquid discharged into the lower part of the flow dividing pipe head 9 through the lower liquid guide pipe 10 enters the inner side of the upper liquid spraying box 14 for flow division and spraying after passing through the flow dividing cylinder 7, the connecting pipe 8, and the deceleration of the main sleeve 5 in sequence. The upper fluorescent magnetic suspension liquid discharged into the flow dividing pipe head 9 through the upper liquid guide pipe 11 enters the inner side of the lower liquid spraying box 15 after passing through the stepped drainage pipe 16 and the deceleration of the auxiliary sleeve 6. The steering diversion channel 26 and the adjusting plug 31 perform secondary deceleration on the discharged fluorescent magnetic suspension liquid. At the same time, under the reverse rotation between the upper liquid spraying box 14 and the lower liquid spraying box 15, fluorescent magnetic suspension liquids with different rotation directions are generated above and below the mixing turbulence ring plate 12, which is conducive to the rapid mixing of the intersection part of the upper and lower fluorescent magnetic suspension liquids. The rotational movement of the upper liquid spraying box 14 and the lower liquid spraying box 15 makes the fluorescent magnetic suspension liquid sprayed from the liquid spraying holes 28 of the steering diversion channel 26 and the stirring pipe 27 in a rotating state. The sprayed fluorescent magnetic suspension liquid has a tendency of rotational movement, avoiding the direct spraying of the fluorescent magnetic suspension liquid onto the mixing turbulence ring plate 12. At the same time, the fluorescent magnetic suspension liquid initially mixed and flowing into the outer mixing ring box 13 will be sprayed obliquely through the diversion cavity 21 and the drain hole 22 in sequence and intersect with the above-mentioned fluorescent magnetic suspension liquid with a tendency of rotational movement to generate turbulence and mix. The stirring pipe 27 can assist in stirring and mixing the upper and lower fluorescent magnetic suspension liquids at the intersection, avoiding the mixing method of violent collision between the fluorescent magnetic suspension liquids, enabling the fluorescent magnetic suspension liquid to be gently mixed inside the dispensing tank 1 while also having a good dispensing effect.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
