[0002] Phosphating solution is a mixed chemical reagent, mainly composed of zinc nitrate, phosphoric acid, zinc oxide and water. The usage is to first calculate the amount of each chemical required according to the size of the phosphating tank, then put zinc oxide in the mixing barrel, add water and stir into a thick slurry, then slowly add phosphoric acid while stirring, and when the solution has finished releasing heat, add it to the phosphating tank that has been added with water, and finally add zinc nitrate to the phosphating tank, stir evenly and it can be used.

[0003] The prior art, such as the one disclosed in the publication number CN218981570U, discloses a phosphating liquid processing and production reactor, which includes: a reaction tank, a supply and discharge part, and a mixing part; the reaction tank is made of metal, and a cover plate is installed on the reaction tank; the outer wall of the reaction tank is welded with supporting legs in a circular array. This technology solves the problem that when adding raw materials, raw material bags or workers are easy to fall into the reactor, causing irreparable damage, but the above technology has the following shortcomings in actual use:

[0004] In the above technology, when adding phosphoric acid, since phosphoric acid releases a large amount of heat during the reaction, phosphoric acid needs to be slowly poured along the inner wall of the reactor to slow down the degree of phosphoric acid reaction. However, there is no component for automatically adding phosphoric acid in the above technology, so manual addition is required. However, manual addition cannot accurately control the amount of addition, and it is very easy to increase the amount of phosphoric acid added, resulting in a violent reaction and release of a large amount of heat, which not only damages the reactor but also causes harm to the operator. Utility Model Content

[0005] The utility model aims to solve the problem that phosphoric acid cannot be automatically added along the inner wall of a reactor in the prior art, and proposes a phosphating liquid processing and production reactor.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A phosphating liquid processing and production reactor, including a phosphating liquid processing and production reactor, including a reaction tank 1, a support ring 8 and four support legs 9 are fixedly connected to the lower end of the reaction tank 1, a feed port 2, a control valve 3, an air hole 7, a discharge port 10 and four support columns 6 are fixedly installed on the upper end of the reaction tank 1, a support plate 5 is fixedly connected to the upper part of the four support columns 6, a drive motor 4 is fixedly installed on the support plate 5, a rotating shaft 17 is connected to the output end of the drive motor 4, a balancing disc 21, a centrifugal discharge pipe 14 and an impeller 18 are arranged on the rotating shaft 17, and the centrifugal discharge pipe 14 is opened when the rotating shaft 17 rotates, and phosphoric acid is slowly thrown to the inner wall of the reaction tank 1, so as to slow down the reaction degree of phosphoric acid and avoid damage to the reactor and the operator due to the violent reaction;

[0022] The discharge port 10 is fixedly installed with a valve 11, and the discharge port 10 is opened by the valve 11 to discharge the reactants in the reaction tank 1. The balancing disc 21 is a disc structure with a central opening. The balancing disc 21 is fixedly sleeved on the rotating shaft 17 through the central opening. The upper end of the balancing disc 21 is fixedly connected with a perfusion pipe 12, and the upper end of the perfusion pipe 12 extends to the outer end of the reaction tank 1, and phosphoric acid is added into the balancing disc 21 through the perfusion pipe 12.

[0023] A transport pipe 22 is fixedly connected to the rotating shaft 17, and the transport pipe 22 is in a U-shaped shape. A collection chamber 19 is provided in the balancing disc 21, and a feed hole 20 is provided at the lower end of the collection chamber 19. The upper end of the collection chamber 19 and the feed hole 20 are respectively connected to the lower end of the perfusion pipe 12 and the upper end of the transport pipe 22, and the added phosphoric acid flows through the perfusion pipe 12, the collection chamber 19 and the transport pipe 22.

[0024] The balancing disc 21 is fixedly connected to a fixing column 13, and one end of the fixing column 13 away from the balancing disc 21 is fixedly connected to the inner wall of the reaction tank 1, and the balancing disc 21 is fixed by the fixing column 13, and the centrifugal discharge pipe 14 is integrally formed with a limiting pipe 16;

[0025] A storage chamber 15 is provided in the limiting tube 16, and the storage chamber 15 is connected to the lower end of the transport pipe 22. A return spring 24 is welded to the inner wall of the storage chamber 15, and a movable ball 23 fixedly connected to the return spring 24 is provided in the movable sleeve of the storage chamber 15. Figure 4 As shown, when the rotating shaft 17 is stationary, the moving ball 23 is located at the connection between the storage chamber 15 and the centrifugal discharge pipe 14, and the centrifugal discharge pipe 14 is closed. When the rotating shaft 17 rotates, under the action of centrifugal force, the moving ball 23 moves to the centrifugal discharge pipe 14, opens the centrifugal discharge pipe 14, and slowly throws the phosphoric acid to the inner wall of the reaction tank 1, so that the phosphoric acid slowly flows downward along the inner wall of the reaction tank 1 and slowly reacts with the raw materials in the reaction tank 1 to achieve the effect of reducing heat release. Afterwards, when the rotating shaft 17 stops, the elastic force of the reset spring 24 is used to move the moving ball 23 to the connection between the storage chamber 15 and the centrifugal discharge pipe 14, and the centrifugal discharge pipe 14 is closed again.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] The driving motor 4 is turned on to drive the rotating shaft 17 to rotate, and then phosphoric acid is injected into the perfusion pipe 12. The phosphoric acid flows into the collecting chamber 19 through the perfusion pipe 12. The collecting chamber 19 is kept stable by the balancing disc 21 and the fixing column 13. The phosphoric acid enters the transport pipe 22 through the feed hole 20, and flows into the storage chamber 15 through the transport pipe 22. At this time, the centrifugal force generated by the rotation of the rotating shaft 17 causes the moving ball 23 to move into the centrifugal discharge pipe 14, and then the centrifugal discharge pipe 14 is opened. At the same time, phosphoric acid will enter the centrifugal discharge pipe 14 with the movement of the moving ball 23, and the phosphoric acid will be thrown from the centrifugal discharge pipe 14 to the inner wall of the reaction tank 1 by the centrifugal force, so that the phosphoric acid slowly flows downward along the inner wall of the reaction tank 1 and slowly reacts with the raw materials in the reaction tank 1. At the same time, the three pairs of impellers 18 stir it, and the gas generated during the stirring process will flow out from the air hole 7. After the stirring is completed, the valve 11 is turned to discharge it from the discharge port 10.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
