Description

Technical Field

[0001] The present application relates to the technical field of iron phosphate production, and specifically to an iron solution reaction device for iron phosphate production. Background Art

[0002] Ferric phosphate, also known as ferrous phosphate and ferric orthophosphate, is an inorganic compound with the chemical formula FePO4. It is a white or light red crystalline powder, soluble in hydrochloric acid and sulfuric acid, insoluble in cold water and nitric acid, and is mainly used as a nutritional supplement (iron fortifier) ​​in the food industry. When using iron salts and phosphates to prepare iron phosphate, the iron salts and phosphates are added to a reactor, and the iron salts and phosphates undergo a precipitation reaction to produce iron phosphate.

[0003] When iron salt and phosphate react inside the reactor, the stirring component will mix the iron salt and phosphate. The iron phosphate produced by the reaction of iron salt and phosphate will precipitate to the bottom of the reactor. However, when the iron phosphate is inside the reactor, it is easily driven by the iron salt and phosphate solution to float upward. The iron phosphate can easily affect the reaction of the iron salt and phosphate, and the iron phosphate is not easy to be discharged from the bottom of the reactor.

[0004] Therefore, there is an urgent need for an iron solution reaction equipment for iron phosphate production to solve the problem that iron phosphate easily affects the reaction between iron salt and phosphate and iron phosphate is not easy to be discharged from the bottom of the reactor. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides an iron solution reaction equipment for the production of iron phosphate, which has the advantage of improving the processing rate of iron phosphate and solving the problems that iron phosphate easily affects the reaction between iron salt and phosphate and that iron phosphate is not easy to be discharged from the bottom of the reactor.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an iron solution reaction device for producing iron phosphate, comprising a reactor body, a liquid inlet and a liquid outlet, wherein the liquid inlet and the liquid outlet are respectively connected to the top and the bottom of the reactor body, a stirring mechanism is arranged inside the reactor body, and a heating mechanism is arranged outside the reactor body;

[0007] The stirring mechanism includes a driving motor, a connecting rod, a stirring plate, a supporting ring and a filter screen. The driving motor is arranged at the middle position of the top of the reactor body. One end of the connecting rod is fixedly connected to the output end of the driving motor. Several groups of stirring plates are welded to the outer surface of the connecting rod. The supporting ring is welded to the inner side of the reactor body. The filter screen is arranged on the inner side of the supporting ring.

[0008] When the iron salt and the phosphate solution react inside the reactor body, the connecting rod drives the stirring plate to rotate to stir the iron salt and the phosphate solution, so that the iron salt and the phosphate are mixed more thoroughly, thereby increasing the production rate of iron phosphate. At the same time, the iron phosphate precipitated to the bottom of the reactor body is blocked and filtered by the filter net, making it difficult for the iron phosphate to float upward and affect the reaction of the iron salt and the phosphate solution, thereby further increasing the reaction rate of the iron salt and the phosphate solution.

[0009] Preferably, the connecting rod is connected to the supporting ring via a bearing.

[0010] Preferably, a plurality of groups of interconnected small holes are provided on both sides of the stirring plate.

[0011] Preferably, several groups of stirring plates are evenly distributed on the outer surface of the connecting rod.

[0012] Preferably, the heating mechanism includes a heating cylinder, an electric heating tube and a temperature sensor, the heating cylinder is welded to the outside of the reactor body, several groups of the electric heating tubes are installed inside the heating cylinder, and the temperature sensor is arranged on the outside of the reactor body.

[0013] Preferably, the top and bottom of the heating cylinder are connected with a water inlet and a water outlet.

[0014] In summary, the present application includes at least one of the following beneficial effects:

[0015] 1. The iron solution reaction equipment for producing iron phosphate, when the iron salt and the phosphate solution react inside the reactor body, the connecting rod drives the stirring plate to rotate to stir the iron salt and the phosphate solution, so that the iron salt and the phosphate are mixed more thoroughly, thereby improving the production rate of iron phosphate, and at the same time, the iron phosphate precipitated to the bottom of the reactor body is blocked and filtered by the filter net, so that the iron phosphate is not easy to float upward to affect the reaction of the iron salt and the phosphate solution, thereby further improving the reaction rate of the iron salt and the phosphate solution, making the reactor body more convenient to use.

[0016] 2. In the iron solution reaction equipment for producing ferric phosphate, water can be introduced into the heating cylinder, and the electric heating tube heats the water. The heated water heats the iron salt and phosphate solution inside the reactor body, thereby changing the temperature of the iron salt and phosphate solution inside the reactor body, allowing the iron salt and phosphate solution to react at a suitable temperature, thereby accelerating the reaction rate of the iron solution inside the reactor body and increasing the production speed of ferric phosphate.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Specifically, the stirring mechanism includes a driving motor 111, a connecting rod 112, a stirring plate 113, a support ring 114 and a filter screen 115. The driving motor 111 is arranged in the middle position of the top of the reactor body 1, one end of the connecting rod 112 is fixedly connected to the output end of the driving motor 111, several groups of stirring plates 113 are welded to the outer surface of the connecting rod 112, several groups of connected small holes are opened on both sides of the stirring plate 113, and several groups of stirring plates 113 are evenly distributed on the outer surface of the connecting rod 112.

[0025] Through the above technical solution, when the iron salt and the phosphate solution enter the reactor body 1 from the liquid inlet 2, the drive motor 111 is started, and the drive motor 111 drives the connecting rod 112 to rotate. When the connecting rod 112 rotates, it drives the stirring plate 113 to rotate. The stirring plate 113 rotates to stir the iron salt and the phosphate solution, so that the iron salt and the phosphate are mixed more thoroughly, thereby improving the production rate of iron phosphate. At the same time, the iron phosphate precipitated to the bottom of the reactor body 1 is blocked and filtered by the filter screen 115, so that the iron phosphate is not easy to float upward to affect the reaction of the iron salt and the phosphate solution, thereby further improving the reaction rate of the iron salt and the phosphate solution.

The heated water heats the iron salt and phosphate solution inside the reactor body 1, thereby changing the temperature of the iron salt and phosphate solution inside the reactor body 1, allowing the iron salt and phosphate solution to react at a suitable temperature, thereby accelerating the reaction rate of the iron salt and phosphate.

[0028] During use, when the iron salt and the phosphate solution react inside the reactor body 1, the connecting rod 112 drives the stirring plate 113 to rotate to stir the iron salt and the phosphate solution, so that the iron salt and the phosphate are mixed more thoroughly, thereby increasing the production rate of iron phosphate.
