Description

Technical Field

[0001] This utility model relates to the field of ammonium sulfate production technology, specifically an ammonium sulfate preparation reactor. Background Technology

[0002] An ammonium sulfate production unit is a reaction device used to mix sulfuric acid and liquid ammonia. It can also evaporate and concentrate the ammonium sulfate solution and cool it to crystallize, thereby obtaining the finished ammonium sulfate product.

Furthermore, because the filter element is relatively flat, large ammonium sulfate crystals cannot be discharged from the reactor by themselves after the cover is opened, requiring manual discharge by the operator, which is inconvenient. Therefore, in view of the above situation, there is an urgent need to develop an ammonium sulfate preparation reactor to overcome the shortcomings in current practical applications.

The stirring rod is fixedly connected to the outer side of the support rod, and its other end is fixedly connected to the outer side of the reaction tank. The scraper, which abuts against the inner wall and the movable base plate, is used to stir the raw materials located inside the reaction tank in conjunction with the rotation of the support rod, and to clean the inner wall of the reaction tank. The cleaning brush is located between the scraper and the annular filter frame, is fixedly connected to the scraper, and abuts against the annular filter frame. It is used to clean the annular filter frame in conjunction with the rotation of the support rod. The inner side of the support rod is also provided with a connecting cavity connected to the control component, which is used to guide the air flow. The connecting cavity is connected to a fixed pipe fixedly connected to the bottom wall of the support rod. The other end of the fixed pipe is connected to an air blowing box located inside the annular filter frame. Several air blowing pipes are fixedly connected to the wall of the air blowing box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During operation, the raw material enters the inner side of the reaction tank through the feed pipe. The control component drives the stirring component to agitate the raw material located inside the reaction tank. Simultaneously, the control component injects air into the stirring component, which uses the air to blow the raw material from the center to the edge, thus changing the raw material's position and ensuring thorough agitation. As ammonium sulfate crystals are formed, the isolation component discharges the supersaturated ammonium sulfate solution. The stirring component then drives the isolation component to rise and fall, separating it from the reaction tank and placing it inside the annular baffle. The stirring component, in conjunction with the airflow, agitates the ammonium sulfate crystals located on the isolation component. The ammonium sulfate crystals are fed into the recycling bin for automatic recovery. Compared to existing technologies, the reaction device structure is relatively simple, but in actual use, it cannot fully stir the material, resulting in low reaction efficiency. Furthermore, due to the relatively flat filter element, large ammonium sulfate crystals cannot be discharged from the reactor automatically after the cover is opened, requiring manual discharge by operators, which is inconvenient. By setting up a stirring mechanism, the raw materials can be stirred more thoroughly, and the ammonium sulfate crystals can be automatically discharged, greatly improving production efficiency, effectively reducing the labor intensity of operators, and making it more convenient to use.

Detailed Implementation

[0017] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0019] Please see Figure 1 In one embodiment of this utility model, an ammonium sulfate preparation reactor includes: a reaction tank 1, wherein a feed pipe 2 is fixedly connected to the top wall of the reaction tank 1, and a base 4 is provided on the outer side of the bottom wall of the reaction tank 1; an annular baffle 3, which is arranged around the outer side of the bottom of the reaction tank 1, fixedly connected to the outer wall of the reaction tank 1, and fixedly connected to the base 4 through a support frame 5, for supporting the reaction tank 1 in conjunction with the base 4 and shielding the output ammonium sulfate particles; and a stirring mechanism, which is connected to the reaction tank 1 and to the inner wall of the reaction tank 1, for circulating stirring of the ammonium sulfate in conjunction with the reaction tank 1 and completing the preparation of the ammonium sulfate. Automatic discharge of crystals; recovery box 6, which is located between the annular baffle plate 3 and the base 4 and connected to the base 4, is used to receive and store the discharged ammonium sulfate crystals in conjunction with the annular baffle plate 3; wherein, the stirring mechanism includes: an isolation component, which is slidably connected to the inner wall of the bottom end of the reaction tank 1, and is used to store the raw materials entering the inner side of the reaction tank 1 in conjunction with the reaction tank 1; a stirring component, which is connected to the reaction tank 1 and the isolation component, and is used to realize the lifting and lowering of the isolation component; a control component, which is connected to the stirring component, and is used to drive the stirring component to realize the comprehensive stirring of the raw materials located inside the reaction tank 1.

[0020] In this embodiment, the support frame 5 is symmetrically arranged on the outside of the annular baffle plate 3, with one end fixedly connected to the annular baffle plate 3 and the other end fixedly connected to the base 4. When the device is running, the raw material enters the inside of the reaction tank 1 along the feed pipe 2. The control component drives the stirring component to stir the raw material located inside the reaction tank 1. At the same time, the control component can inject air into the inside of the stirring component. The stirring component uses air to blow the raw material located in the center to the edge, realizing the change of the raw material position, thereby enabling the raw material to be fully stirred. As ammonium sulfate crystals are generated, the isolation component completes the discharge of the supersaturated ammonium sulfate solution. The stirring component drives the isolation component to rise and fall, and the isolation component separates from the reaction tank 1 and enters the inside of the annular baffle plate 3. The stirring component, in conjunction with the airflow, sends the ammonium sulfate crystals located on the isolation component into the inside of the recovery tank 6, completing the automatic recovery of the ammonium sulfate crystals. Compared with the existing technology, the reaction device structure is relatively simple. However, in actual use, it is impossible to fully stir the materials, resulting in low reaction efficiency. Furthermore, because the filter element is relatively flat, large particles of ammonium sulfate crystals cannot be discharged from the reactor by themselves after the cover is opened, requiring manual discharge by the operator, which is inconvenient. By setting up a stirring mechanism, the raw materials can be stirred more comprehensively, and the ammonium sulfate crystals can be automatically discharged, greatly improving production efficiency, effectively reducing the labor intensity of the operators, and making it more convenient to use.

After the ammonium sulfate crystals are generated, the solenoid valve located inside the drain pipe 8 is opened. After the supersaturated ammonium sulfate solution is filtered by the annular filter frame 25, it is discharged from the drain pipe 8. After the supersaturated ammonium sulfate solution is discharged, the stirring assembly, together with the annular filter frame 25, drives the movable base plate 7 to move downward. The movable base plate 7 separates from the reaction tank 1 and falls into the inner side of the annular baffle plate 3.
