Heated reaction storage tank 1 provides reaction storage space when preparing chromium-free passivating agent. Heated reaction storage tank 1 is used to react and store various raw materials when preparing chromium-free passivating agent. At the same time, heated reaction storage tank 1 can accelerate the reaction speed between various reactants by utilizing its heating feature. The heating technology in heated reaction storage tank 1 is conventional heating technology. Support plate 28 facilitates the fixation and support of heated reaction storage tank 1. The stirring device 2 is installed on the sealed top cover 3 at the top opening of the heated reaction tank 1. The stirring device 2 is used to stir the powdered reactants and liquid reactants in the heated reaction tank 1. The stirring device 2 is used to ensure that the powdered additives and raw material solutions in the heated reaction tank 1 are fully contacted and dissolved, which can prevent the powdered additives from not contacting the raw materials in the lower layer. The sealed top cover 3 is used in conjunction with the heated reaction tank 1 to keep the various raw materials in a relatively closed environment during the reaction, so as to prevent the reaction gases from escaping. At the same time, the sealed top cover 3 is convenient for fixing and supporting the stirring device 2. The top cover lifting structure 4 is set on the support fixing plate 28 between the top cover 3 and the sealing top cover 3. The top cover lifting structure 4 is used to open or close the sealing top cover 3 at the top opening of the heatable reaction storage tank 1. The top cover lifting structure 4 facilitates the opening or closing of the sealing top cover 3 at the top opening of the heatable reaction storage tank 1. At the same time, the support fixing plate 28 is also used to fix and support the top cover lifting structure 4.

[0018] Furthermore, such as Figure 2 As shown, the stirring device 2 includes an upper and lower stirring assembly 5 installed on the sealed top cover 3, a support and limiting frame 6 installed on the sealed top cover 3, and an emulsifying shearing assembly 7 installed in the support and limiting frame 6.

The supporting part of the support and limiting frame 6 extends through the sealed top cover 3 into the heatable reaction storage tank 1. The upper and lower stirring assembly 5 facilitates the rapid pressing of powdery materials floating on the surface of the raw material liquid into the raw material liquid, so that the powder will be quickly wetted. The support and limiting frame 6 is used to fix and support the emulsifying shearing assembly 7. The emulsifying shearing assembly 7 is used to quickly suck the powdery additives pressed into the raw material liquid to a position near the bottom of the raw material liquid, and to rapidly and continuously cut, crush and stir the powder at the bottom of the raw material liquid, so that the clumps of powder in the liquid can be quickly integrated into the raw material liquid.

[0019] Furthermore, such as Figure 1 and Figure 3 As shown, the emulsification shearing assembly 7 includes a drive motor 8 mounted on a support limiting frame 6, a stirring shaft 9 located at the output end of the drive motor 8, an emulsification rotor 10 located at the end of the stirring shaft 9, stirring blades 11 sleeved on the stirring shaft 9, and a fixed seat 12 rotatably mounted on the stirring shaft 9.

A control module 27 is provided on the support frame 16. The support frame 16 is used to fix and support the two first lifting rods 17 and the control module 27. At the same time, the support frame 16 is used to install the upper and lower stirring assembly 5 on the sealed top cover 3. The two first lifting rods 17 drive the flipping pressing plates 19 to move up and down in the heatable reaction storage tank 1. The connecting slide rods 18 are used to fix the first lifting rods 17 and the flipping pressing plates 19 together. The flipping pressing plates 19 are used to move up and down in the solution under the drive of the first lifting rods 17, thereby quickly pressing the powder into the raw material liquid and making the powder quickly wet.

[0022] Furthermore, such as Figure 1 , Figure 5 as well as Figure 6 As shown, the top cover lifting structure 4 includes a bottom block 20 symmetrically arranged on the support fixing plate 28, a second lifting rod 21 arranged on the bottom block 20, and a connecting block 22 arranged between the lifting end of the second lifting rod 21 and the sealed top cover 3.

The drain pipe 25 is used to discharge the prepared chromium-free passivating agent from the heatable reaction storage tank 1. The electric control switch 26 is used to control the opening or closing of the drain pipe 25.

[0023] Furthermore, such as Figure 1 and Figure 5 As shown, an annular embedded sealing block 23 is provided on the lower surface of the sealing top cover 3, and an annular embedded sealing groove 24 adapted to the annular embedded sealing block 23 is provided at the edge of the upper opening of the heatable reaction storage tank 1; the annular embedded sealing block 23 and the annular embedded sealing groove 24 cooperate with each other to facilitate the sealing top cover 3 to be embedded and snapped into the upper opening of the heatable reaction storage tank 1.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, the stirring shaft 9 rotates through the mounting base 13 and the sealing top cover 3, the stirring blade 11 is located on the stirring shaft 9 near the emulsifying rotor 10 above, and the fixed base 12 is located between the emulsifying rotor 10 and the stirring blade 11.

[0025] like Figures 1-6 As shown, the principle of the chromium-free passivating agent reaction device provided in this embodiment is as follows: When in use, the operator issues an opening command to the control module 27 through an external control computer. The two second lifting rods 21 extend at the same time. The two extended second lifting rods 21 move above the heatable reaction storage tank 1 with the sealed top cover 3. At the same time, the stirring device 2 detaches from the heatable reaction storage tank 1. The raw material liquid is injected into the heatable reaction storage tank 1, and then the powder to be added is poured into the heatable reaction storage tank 1. The control computer issues a tank closing command to the control module 27. The two second lifting rods 21 retract simultaneously. The retracted two second lifting rods 21 move the sealing top cover 3 to the initial position, so that the sealing top cover 3 is embedded in the opening of the sealing cover on the heatable reaction storage tank 1. At the same time, a part of the working structure in the stirring device 2 also moves to the initial position, so that a part of the working structure in the stirring device 2 is in the heatable reaction storage tank 1, and the heatable reaction storage tank 1 is in a suitable constant temperature state. The operator sends a work command to the control module 27 via the computer, which controls the two first lifting rods 17 to quickly extend and retract. Under the action of the two first lifting rods 17, the two connecting slide rods 18 and the flipping pressing plate 19 installed at the end press the powder floating on the surface of the raw material liquid into the raw material liquid. After the reciprocating pressing of the flipping pressing plate 19, the powder will be quickly wetted. The two first lifting rods 17 stop working, and the flipping pressing plate 19 will return to the initial state, that is, the flipping pressing plate 19 is tightly attached to the sealing top cover 3. At this time, the wetted powder will clump together. The drive motor 8 drives the stirring shaft 9 to rotate. The rotating stirring shaft 9 drives the stirring blades 11 and the emulsifying rotor 10 to rotate at high speed. The stirring blades 11 agitate the solution water to form a suction vortex. The powder that is wetted and clumps on the surface of the solution enters the solution near the stirring blades 11 with the suction vortex. Under the action of the rotation of the emulsifying rotor 10, the wetted and clumped powder is sucked into the rotor working chamber 15. The rotating emulsifying rotor 10 and the rotor working chamber 15 rapidly and continuously cut, crush and stir the entering wetted and clumped powder. The cut and crushed powder will come out from the holes on the rotor working chamber 15 and quickly dissolve or react with the raw material liquid. The undissolved material will be further cut, crushed and stirred by the emulsifying rotor 10 again, so that the powder and the lower raw material can fully contact each other and achieve the effect of rapid dissolution, while avoiding the impact on the quality of the chromium-free passivating agent produced. After the powder has completely dissolved with the raw materials, the computer sends a shutdown command to the control module 27, the emulsification shearing component 7 stops operating, the thermostatic state of the heatable reaction storage tank 1 is closed, and the computer sends a discharge command to the control module 27 to open the electrical control switch 26. The solution prepared in the heatable reaction storage tank 1 is discharged through the drain pipe 25 to rinse the inside of the device.
