It is also used for primer before painting and friction reduction lubrication in subsequent processes. The steel wire phosphating tank in the prior art needs to use steel wire rollers to press the steel wire into the phosphating solution.

[0056] Please refer to Figures 1 to 10, an embodiment of the present invention provides a steel wire phosphating tank with a raw material recovery function, comprising:

[0058] The reflux mechanism 2 comprises a first sub-trough 21 arranged in the middle of the main tank 1, and a second sub-trough 26 arranged on one side of the main tank 1, wherein the second sub-trough 26 is provided with a phosphating solution, the bottom of the first sub-trough 21 is connected with the second sub-trough 26, and the two ends of the main tank 1 along the first direction are connected with the second sub-trough 26, and a first driving part is arranged in the middle of the first sub-trough 21, and the first driving part is used to drive the phosphating solution at the bottom of the first sub-trough 21 to flow upward into the main tank 1, and then flow back to the inside of the second sub-trough 26, wherein, as Figure 1 and Figure 2 As shown, a liquid inlet 28 communicating with the second sub-tank 26 is provided at the bottom end of the first sub-tank 21, and the first driving unit includes a mounting plate 24 disposed on the main tank 1, and a first propeller agitator 25 disposed on the mounting plate 24. The first propeller agitator 25 sends the phosphating solution in the first sub-tank 21 upward into the main tank 1, and the phosphating solution in the second sub-tank 26 flows into the first sub-tank 21 from the liquid inlet 28 to replenish the phosphating solution in the first sub-tank 21;

[0059] Recovery tanks 3, arranged at the bottom of both ends of the main tank 1 along the first direction, for containing the recovered phosphating solution;

[0060] Two first recovery mechanisms 4 are respectively arranged at two connecting positions between the second auxiliary tank 26 and the main tank 1, and are used to block the phosphating solution from flowing back and guide the phosphating solution into the recovery tank 3. The user can choose to let the phosphating solution flow back to the second auxiliary tank 26 for reuse, or choose to let the phosphating solution flow into the recovery tank 3 for recovery according to needs.

[0061] In some embodiments, the side walls at both ends of the main tank 1 are provided with a reflux port 27 connected to the second auxiliary tank 26, and the bottom of the main tank 1 is provided with a recovery port 41 connected to the recovery tank 3. The first recovery mechanism 4 includes:

[0062] An L-shaped plate 42 is provided at the reflux port 27 to block the reflux port 27 and the recovery port 41. The L-shaped plate 42 is provided with a first channel 43 connecting the main tank 1 and the recovery tank 3, and a second channel 44 connecting the main tank 1 and the second auxiliary tank 26;

[0063] The blocking plate 48 is provided at the reflux port 27 and has a reflux state and a recovery state. The reflux state means that the blocking plate 48 blocks the first channel 43, and the recovery state means that the blocking plate 48 blocks the second channel 44. Figure 3 and Figure 4As shown, a first sealing strip 45 is provided at the outer edge of the first channel 43. In the reflux state, the blocking plate 48 contacts the first sealing strip 45 to achieve a better sealing effect, and a second sealing strip 46 is provided at the outer edge of the second channel 44 to ensure that the blocking plate 48 has a good sealing effect in the recovery state;

[0064] The second driving part is arranged on the outer wall of the main tank 1, and is used to drive the blocking plate 48 to switch between the reflux state and the recovery state, wherein Figure 2 and Figure 4 As shown, the second driving part includes a driving shaft 47 that passes through the sealing plate 48 and the side wall of the main groove 1. The axis of the driving shaft 47 extends in the left-right direction, and the end of the driving shaft 47 outside the main groove 1 is provided with a worm gear 49, and a micro motor 410 is provided on one side of the worm gear 49. The output shaft end of the micro motor 410 is provided with a worm 411, and the worm gear 49 is meshingly connected with the worm gear 411. The micro motor 410 drives the worm gear 411 to rotate, and the meshing drives the worm gear 49 and the driving shaft 47 to rotate, thereby driving the sealing plate 48 to swing, thereby achieving the purpose of switching the reflux state and the recovery state.

[0065] In some embodiments, the reflux mechanism 2 also includes two first overflow plates 22 arranged in the first sub-tank 21 and distributed along the first direction, the first driving unit is arranged between the two first overflow plates 22, and two second overflow plates 29 are arranged in the main tank 1, and the two second overflow plates 29 are respectively located on the sides away from each other of the first overflow plates 22; the heights of the bottom end surface of the reflux port 27, the top surfaces of the first overflow plate 22 and the second overflow plate 29, and the top surface of the main tank 1 are increased in sequence, so that the phosphating liquid overflowing from the top of the second overflow plate 29 can flow into the second sub-tank 26 through the reflux port 27, and will not flow out of the phosphating tank beyond the top surface of the main tank 1.

[0066] Among them, Figure 2As shown, the steel wire can be placed on the top surface of the first overflow plate 22 and the second overflow plate 29, so that a phosphating liquid flow layer is formed between the tops of the two plates. The concentration of this part of the phosphating liquid in contact with the steel wire will be reduced, and it will overflow and be discharged from the top of the second overflow plate 29. Through the first recovery mechanism 4, this part of the phosphating liquid can flow into the second auxiliary tank 26 through the reflux port 27, and can also flow into the recovery tank 3 through the recovery port 41, which solves the problem that the existing phosphating tank does not recover this part of the phosphating liquid with reduced concentration, and avoids causing uneven overall concentration of the phosphating liquid and reduced phosphating effect. Optionally, the first overflow plate 2 2, a plurality of first steel wire channels 23 arranged in the front-to-back direction are provided at the top of the second overflow plate 29, a second steel wire channel 210 corresponding to the first steel wire channel 23 is provided at the top of the second overflow plate 29, and main steel wire channels 11 corresponding to the first steel wire channels 23 are provided on the left and right side walls of the main groove 1, and steel wires can be placed in each steel wire channel, so that part of the phosphating solution flows through the first steel wire channel 23 and the second steel wire channel 210, and the other part still flows from the top of the first overflow plate 22 and the second overflow plate 29, so that the thickness of the phosphating solution flow layer is increased, and the situation of insufficient phosphating caused by too thin a phosphating solution flow layer is avoided.

[0067] In some embodiments, a plurality of guide mechanisms 7 are provided between adjacent first overflow plates 22 and second overflow plates 29, and the guide mechanisms 7 are evenly arranged along a first direction and a second direction, and the first direction and the second direction are perpendicular to each other, and the guide mechanisms 7 are used to guide the phosphating solution at the bottom of the main tank 1 to flow upward;

[0068] Among them, Figure 2 and Figure 7 As shown, the second direction is Figure 2 In the front and back directions, the flowing phosphating solution can destroy the original phosphating solution flow layer. The user can choose to retain the phosphating solution flow layer to facilitate the subsequent recovery of the phosphating solution with reduced concentration, or choose to destroy the phosphating solution flow layer to ensure that the phosphating solution is mixed more fully and avoid uneven concentration.

[0069] In some embodiments, the guide mechanism 7 includes a second propeller agitator 71 disposed at the bottom of the main tank 1, and a first guide plate 72 disposed at one side of the second propeller agitator 71, the first guide plate 72 extends from bottom to top toward the side close to the second propeller agitator 71, a rotatable second guide plate 74 is disposed on the bottom surface of the first guide plate 72, and the first guide plate 72 and the second guide plate 74 are perpendicular to each other;

[0070] Among them, Figure 2 and Figure 7 As shown, the second propeller agitator 71 drives the phosphating solution upward, and the phosphating solution is inclined to flow upward under the action of the first guide plate 72, so as to prevent the second propeller agitator 71 from driving the phosphating solution to flow directly to the steel wire and reduce the shaking of the steel wire. In addition, the second guide plate 74 further guides the phosphating solution, and also prevents the phosphating solution from flowing directly to the steel wire.

[0071] like Figure 7 and Figure 8 As shown, a linkage shaft 73 is provided in the middle of the first guide plate 72, and the axial extension direction of the linkage shaft 73 is perpendicular to the first guide plate 72. The second guide plate 74 is connected to the linkage shaft 73 and rotates around the linkage shaft 73. An indicator plate 75 connected to the linkage shaft 73 is provided at the other end of the first guide plate 72. The indicator plate 75 is parallel to the second guide plate 74. The user can swing the indicator plate 75 to drive the second guide plate 74 to swing through the linkage shaft 73 to achieve the purpose of adjusting the angle of the second guide plate 74. Furthermore, a threaded butterfly bolt 76 is penetrated through the middle of the indicator plate 75, and a rubber pad 77 is provided on the top surface of the second guide plate 74 within the rotation arc range of the butterfly bolt 76. By rotating the butterfly bolt 76 to abut against the rubber pad 77, the static friction force is increased by pressure, and the indicator plate 75 is locked, thereby achieving the purpose of locking the second guide plate 74. Further, the second guide plate 74 is far A plurality of connecting rods 78 are provided through the end of the linkage shaft 73, and a third guide plate 79 is provided at both ends of each connecting rod 78 to more accurately guide the flow of the phosphating solution. Optionally, the first guide plate 72 is detachably connected to the bottom wall of the main tank 1, and a first mounting groove 710 is provided at the bottom of the first guide plate 72. A connecting screw 711 is provided through the first mounting groove 710, and the connecting screw 711 is threadedly connected to the bottom wall of the main tank 1 to realize the detachable installation of the first guide plate 72. Further, the first guide plate 72 is located on the side of the second propeller agitator 71 close to the first overflow plate 22. For example, the first guide plate 72 located at the right half end of the main tank 1 will guide the phosphating solution to flow toward the second overflow plate 29 on the right side, and the first guide plate 72 located at the left half end of the main control 1 will guide the phosphating solution to flow toward the second overflow plate 29 on the left side, thereby achieving the driving of the phosphating solution mixing and ensuring the stable flow of the phosphating solution to the second overflow plate 29.

[0072] In some embodiments, a second recovery mechanism 8 is detachably mounted on the top of the second overflow plate 29, and the second recovery mechanism 8 is used to recover the residue in the phosphating solution, such as Figure 2 and Fig. 9 As shown, the residual precipitate in the phosphating solution is recovered to prevent it from hitting the surface of the steel wire and causing pits in the phosphating film.

[0073] In some embodiments, the second recovery mechanism 8 comprises:

[0074] The fourth guide plate 81 is detachably mounted on the top of the second overflow plate 29 and has a cross-sectional shape of a semicircular ring;

[0075] The bearing plate 84 is disposed at the bottom of the fourth guide plate 81, and has a first filter screen 86 in the middle, and a first gap is formed between the bearing plate 84 and the second overflow plate 29;

[0076] The carrying box 810 is disposed on the top of the fourth guide plate 81 and has a second filter screen 811 at the bottom.

[0077] like Fig. 9 and Fig.10 As shown, due to the contact of other substances on the surface of the steel wire with the phosphating solution, and the separation of a small part of the phosphating film from the surface of the steel wire, residual precipitation mixed in the phosphating solution is finally formed, and the liquid flow formed by the guide mechanism 7 is restricted by the second overflow plate 29, and after passing through the first gap, it flows along the inner wall of the fourth guide plate 81, and flows back through the first filter screen 86, so that the residual precipitation entrained in the liquid flow remains in the first filter screen 86, and the top of the fourth guide plate 81 is equivalent to the top of the new overflow plate, so the corresponding phosphating solution flow layer is on the top surface of the fourth guide plate 81, and a baffle 812 is provided at the end of the carrier box 810 away from the carrier plate 84, which can block the residual precipitation entrained by this part of the phosphating solution and fall into the second filter screen 811. Optionally, the side wall of the second steel wire channel 210 is provided with a second mounting groove 83, and the bottom of the right end of the fourth guide plate 81 is provided with a plurality of corresponding to the second steel wire channel 210 A T-block 82 is provided, which is inverted and installed in the left and right directions so that the two extended parts at the bottom end of the T-block 82 are inserted into the two second installation grooves 83 of the same second steel wire channel 210, thereby realizing the detachable installation of the fourth guide plate 81; in addition, a connecting stud 87 penetrating the fourth guide plate 81 is provided on the top surface of the carrier plate 84 near the end of the T-block 82, and an assembly plate 88 for the connecting stud 87 to penetrate is provided near the end of the carrier plate 84 of the carrier box 810, and a connecting nut 89 is connected to the top end of the connecting stud 87 through a thread, and the assembly plate 88 and the fourth guide plate 81 are squeezed by the connecting nut 89 to realize the installation of the carrier plate 84 and the carrier box 810; in addition, a concave block 85 is provided on the top surface of the carrier plate 84 away from the T-block 82, and the bottom end of the fourth guide plate 81 is clamped by the concave block 85, thereby further ensuring the stability of the carrier plate 84 after installation.

[0078] In some embodiments, two buffer mechanisms are further provided in the main groove 1 and are located between the first overflow plate 22 and the second overflow plate 29. The buffer mechanisms include a first shock absorbing assembly 5 and a second shock absorbing assembly 6. The first shock absorbing assembly 5 is used to reduce the vibration of the steel wire along the third direction, and the second shock absorbing assembly 6 is used to reduce the vibration of the steel wire along the second direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0079] Among them, the third direction is Figure 2 In the vertical direction, the buffer mechanism effectively prevents the shaking of the steel wire, thereby preventing the increase of wire tension caused by the shaking, which in turn causes breakage and insufficient phosphating.

[0080] In some embodiments, the first shock absorbing assembly 5 includes a plurality of fixed vertical rods 51 disposed on the bottom surface of the main slot 1 and evenly arranged along the second direction, the extension direction of each fixed vertical rod 51 is the third direction, and two slidably connected transverse mounting columns 52 are disposed on the top of each fixed vertical rod 51, the axis of the transverse mounting columns 52 extends in the second direction, and first connecting plates 53 are disposed at both ends of the two transverse mounting columns 52 along the second direction;

[0081] The two transverse mounting columns 52 are provided with self-rotating first rollers 54 at the positions corresponding to the steel wires, and the outer sleeves of the fixed vertical poles 51 are provided with first shock absorbing springs 55, the bottom ends of the first shock absorbing springs 55 are connected to the bottom surface of the main groove 1, and the top ends of the first shock absorbing springs 55 are connected to the bottom ends of a transverse mounting column 52;

[0082] Among them, Figure 2 and Figure 5 As shown, the stable movement of the steel wire is ensured by the rotation of the first roller 54. When vibration occurs in the vertical direction, the steel wire will drive the first roller 54, the transverse mounting column 52 and the first connecting plate 53 to shake up and down. The compression and extension of the first shock-absorbing spring 55 play a buffering role, ultimately achieving the purpose of reducing the vibration of the steel wire in the vertical direction.

[0083] In some embodiments, the second shock absorbing assembly 6 includes two fixed cross bars 61 distributed along the third direction, the axis extension direction of the two fixed cross bars 61 is the second direction, a plurality of second connecting plates 62 are evenly distributed on the two fixed cross bars 61 along the second direction, a sleeve 63 sleeved outside the fixed cross bars 61 is provided between two adjacent second connecting plates 62, two sleeves 63 at the same position on the two fixed cross bars 61 form a group, a longitudinal mounting column 65 is connected between the two ends of the two sleeves 63 in the same group, and the extension direction of the longitudinal mounting column 65 is the third direction;

[0084] A second rotatable roller 66 is provided at the position of the steel wire between the two longitudinal mounting columns 65, and a second damping spring 64 is provided at both ends of each sleeve 63 along the second direction, and the other end of each second damping spring 64 is connected to the nearest second connecting plate 62;

[0085] Among them, Figure 2 and Figure 6 As shown, the rotation of the second roller 66 ensures the stable movement of the steel wire. When vibration occurs in the front-to-back direction, the steel wire will drive the second roller 66, the sleeve 63 and the longitudinal mounting column 65 to shake left and right. The compression and extension of the second shock-absorbing spring 64 play a buffering role, ultimately achieving the purpose of reducing the vibration of the steel wire in the front-to-back direction.

[0086] Usage process:

[0087] First, the steel wire is sequentially passed through the bottom of the main steel wire channel 11, between the two second rollers 66, between the two first rollers 54, the bottom of the second steel wire channel 210, the bottom of the first steel wire channel 23, the bottom of the first steel wire channel 23, the bottom of the second steel wire channel 210, between the two first rollers 54, between the two second rollers 66 and the bottom of the main steel wire channel 11, and then the first shock-absorbing spring 55 is used to reduce the vibration of the steel wire in the vertical direction, and the second shock-absorbing spring 64 is used to reduce the vibration of the steel wire in the front-to-back direction, so as to ensure the stability of the subsequent movement of the steel wire in the left-right direction;

[0088] Then pour the phosphating solution into the second sub-tank 26. The liquid level of the phosphating solution is lower than the lowest point of the reflux port 27. The phosphating solution in the second sub-tank 26 enters the first sub-tank 21 along the liquid inlet 28. Start the first propeller agitator 25 to push the phosphating solution in the first sub-tank 21 upward. Adjust the rotation speed of the first propeller agitator 25 so that the phosphating solution just submerges the steel wire and the bottom of the first steel wire channel 23. Then, the phosphating solution flows along the bottom of the first steel wire channel 23 between the first overflow plate 22 and the second overflow plate 29. After being filled, the liquid overflows and is discharged along the bottom of the second steel wire channel 210, and the first recovery mechanism 4 is adjusted. The micro motor 410 drives the worm 411 to rotate, driving the meshing worm wheel 49 to rotate. The worm wheel 49 and the blocking plate 48 are both installed on the driving shaft 47, so that the micro motor 410 drives the blocking plate 48 to rotate, and the blocking plate 48 is switched to the reflux state, so that the discharged phosphating solution flows into the second channel 44 and the reflux port 27, so as to realize the recycling of the phosphating solution and the balance of the overall concentration of the phosphating solution;

[0089] After long-term use of the phosphating solution, the overall concentration of the phosphating solution has been reduced. At this time, the phosphating solution needs to be recovered, and the phosphating solution driven by the first propulsion agitator 25 is kept just submerged in the steel wire and the bottom of the first steel wire channel 23. The bottom of the first steel wire channel 23 and the bottom of the second steel wire channel 210 are the current phosphating solution flow layer. The concentration of this part of the phosphating solution decreases after contacting the steel wire. The first recovery mechanism 4 can be adjusted, and the micro motor 410 drives the blocking plate 48 to switch to the recovery state, so that the discharged phosphating solution flows into the recovery tank 3 through the first channel 43 and the recovery port 41, and the phosphating solution with reduced concentration is preferentially recovered, and the phosphating solution with reduced concentration is not allowed to flow back, so as to achieve the purpose of fully utilizing the phosphating solution;

[0090] Furthermore, during the use of the phosphating solution, the rotation speed of the first propeller agitator 25 can also be increased to make the steel wire completely submerged in the phosphating solution, and the phosphating solution overflows and discharges along the top of the first overflow plate 22 and the second overflow plate 29 to avoid insufficient phosphating due to less phosphating solution above the steel wire. In order to avoid the bottom liquid between the first overflow plate 22 and the second overflow plate 29 not flowing, it is necessary to start the guide mechanism 7, that is, start the second propeller agitator 71, and the phosphating solution flows upward, and flows upward along the left and right tilts under the influence of the first guide plate 72, and then further adjusted by the second guide plate 74 and the third guide plate 79, and the phosphating solution flow direction is increased. The forward and backward guidance is added, so that the phosphating solution between the two plates can flow chaotically, and the situation of insufficient phosphating of the steel wire caused by the static state is avoided. Among them, the second guide plate 74 and the third guide plate 79 can be adjusted by rotating the indicator plate 75, and then the butterfly bolt 76 is rotated to release the bottom end of the butterfly bolt 76 from the rubber pad 77, so as to achieve the purpose of locking;

[0091] When it is necessary to recover the residual precipitate, the rotation speed of the first propeller agitator 25 is maintained, and the phosphating liquid continues to overflow and discharge along the top of the first overflow plate 22. The first part of the phosphating liquid is acted upon by the guiding mechanism 7 close to the second overflow plate 29, and is guided to the side of the second overflow plate 29, and flows along the side wall of the second overflow plate 29 to the inner wall of the fourth guide plate 81. This part of the phosphating liquid passes through the first filter screen 86, and the residue is filtered and collected. The second part of the phosphating liquid is acted upon by the fourth guide plate 81, and overflows along the top of the fourth guide plate 81, and along the assembly plate 88, it is acted upon by the baffle 812. This part of the phosphating liquid flows through the second filter screen 811, and the residual precipitate is intercepted by the second filter screen 811, and the phosphating liquid falls into the reflux port 27 and the recovery port 41, and is recovered or refluxed by the adjustment and judgment of the first recovery mechanism 4.
