The main unit is mounted on the reactor body and includes a display screen and a button module, with a circuit board and a controller mounted on the circuit board. This invention improves the mixing efficiency of hydraulic raw materials inside the reactor body and is simple and convenient to operate.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] 1. Traditional polyaluminum chloride reactors have shortcomings in pressure monitoring and control, often making it difficult to accurately grasp the pressure dynamics during the reaction process, which can easily lead to unstable product quality and safety hazards. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressure-monitored polyaluminum chloride reactor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polyaluminum chloride reactor based on pressure monitoring, comprising a reactor body, a top cover on the top of the reactor body, a motor bracket on the top of the top cover, a drive motor on the top of the motor bracket, a stirring shaft at the bottom of the drive motor, a first positioning block on one side of the stirring shaft, a first stirring blade on one side of the first positioning block, a second positioning block on one side of the stirring shaft, a second stirring blade on one side of the stirring shaft, a heat insulation layer on one side of the reactor body, a discharge port at the bottom of the reactor body, a connecting rod on one side of the reactor body, a feed port on one side of the reactor body, a feed valve on one side of the feed port, a support frame on one side of the connecting rod, an alarm on the top of the top cover, and a safety valve on the top of the reactor body.

[0007] Preferably, the top of the top cover is provided with a pressure detector housing, and the bottom of the pressure detector housing is threadedly connected to the top of the top cover.

[0008] Preferably, the pressure detector housing has a display screen on its top, and the display screen is connected to the pressure detector housing, with rounded corners at the top.

[0009] Preferably, the top of the pressure detector housing is provided with three operation buttons, and the three operation buttons are mirrored and embedded in the top of the pressure detector housing.

[0010] Preferably, the pressure detector housing has a signal transmission line inside, and the signal transmission line is plugged into and connected to the pressure detector housing.

[0011] Preferably, a pressure sensor is provided at the bottom of the signal transmission line, and the pressure sensor and the signal transmission line are welded together.

[0012] Preferably, the bottom of the pressure detector housing is provided with a positioning bolt, and the positioning bolt is threadedly connected to the pressure detector housing.

[0013] Beneficial effects

[0014] In this invention, a pressure detector housing is installed on the top of the top cover. Inside the housing are a pressure sensor and a signal transmission line. This allows for real-time and accurate monitoring of pressure changes within the reactor vessel by installing a pressure monitoring device on the top of the vessel. The pressure value is then displayed intuitively on a screen, enabling operators to adjust reaction conditions promptly, improving reaction efficiency and product quality. Furthermore, the placement of the pressure sensor and signal transmission line within the pressure detector housing on the top of the top cover minimizes interference from factors such as vigorous stirring of materials within the vessel, ensuring more accurate acquisition of overall pressure data within the reactor. This provides precise basic information for subsequent reaction control, and the intuitive display of pressure values ​​on the screen greatly facilitates operation.

[0015] In this invention, an alarm is installed on the top of the top cover. The alarm can promptly sound an alarm when the pressure is abnormal. In conjunction with the safety valve, it can effectively ensure the safe operation of the reactor and avoid safety accidents caused by excessive pressure. The alarm is located on the top of the top cover, making it easy to detect pressure changes. When the pressure is abnormal, it can quickly issue an alarm signal, and the operator can be notified immediately. In the production process of polyaluminum chloride, the reaction conditions are complex and changeable, and the pressure may suddenly rise due to various factors. The rapid response of the alarm allows the operator to take timely measures to prevent the pressure from deteriorating further. At the same time, the alarm threshold of the alarm can be precisely set according to the design pressure range of the reactor and the actual production needs. This ensures that an alarm is only issued when the pressure truly deviates from the normal range, avoiding false alarms or missed alarms. Attached Figure Description

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-4 A pressure-monitored polyaluminum chloride reactor includes a reactor body 1, a top cover 5 on the top of the reactor body 1, a pressure detector housing 16 on the top of the top cover 5, and a threaded connection between the bottom of the pressure detector housing 16 and the top of the top cover 5. A display screen 18 is located on the top of the pressure detector housing 16 and is connected to the pressure detector housing 16. The top of the display screen 18 has rounded corners. Three operation buttons 21 are located on the top of the pressure detector housing 16, and these three operation buttons 21 are mirrored and embedded in the top of the pressure detector housing 16. A signal transmission line 15 is located inside the pressure detector housing 16 and is plugged into and detached from the pressure detector housing 16. A pressure sensor 14 is located at the bottom of the signal transmission line 15 and is connected to the signal transmission line 16. 5. Welding is adopted. The bottom of the pressure detector housing 16 is provided with a positioning bolt 13, and the positioning bolt 13 is threadedly connected to the pressure detector housing 16. The top of the top cover 5 is provided with a motor bracket 7, the top of the motor bracket 7 is provided with a drive motor 6, the bottom of the drive motor 6 is provided with a stirring shaft 8, one side of the stirring shaft 8 is provided with a first positioning block 9, one side of the first positioning block 9 is provided with a first stirring blade 10, one side of the stirring shaft 8 is provided with a second positioning block 17, one side of the stirring shaft 8 is provided with a second stirring blade 11, one side of the vessel body 1 is provided with a heat insulation layer 2, the bottom of the vessel body 1 is provided with a discharge port 19, one side of the vessel body 1 is provided with a connecting rod 20, one side of the vessel body 1 is provided with a feed port 3, one side of the feed port 3 is provided with a feed valve 4, one side of the connecting rod 20 is provided with a support frame 12, the top of the top cover 5 is provided with an alarm 22, and the top of the vessel body 1 is provided with a safety valve 23.

[0026] Safety valve 23 is connected to the interior of reactor body 1 and can automatically open to release pressure when the pressure is too high, ensuring the safety of the reactor. Reactor body 1 is wrapped with an insulation layer 2 to reduce heat loss during the reaction and maintain the required temperature conditions. During the production of polyaluminum chloride, materials enter reactor body 1 through inlet 3, and drive motor 6 drives the rotation of the first and second stirring blades 10 and 11 of stirring shaft 8, ensuring thorough mixing and reaction of the materials. Pressure sensor 14 monitors the pressure inside the reactor in real time and transmits the pressure signal to display screen 18 via signal transmission line 15. When the pressure exceeds the preset safe pressure range, alarm 22 sounds. If the pressure continues to rise, safety valve 23 automatically opens to release pressure, ensuring the safe and stable operation of the reactor. After the reaction is complete, the product is discharged from outlet 19. Specific Implementation Example 2:

[0028] Reference Figure 1-4A temperature detector is installed on one side of the reactor vessel 1. This allows for the simultaneous acquisition of both pressure and temperature, two crucial parameters. The reaction process of polyaluminum chloride is influenced by both temperature and pressure, and these two factors are interrelated. By monitoring temperature and pressure in real time, operators can more comprehensively and accurately determine the stage of the reaction. For example, during the induction phase of the reaction, changes in pressure and temperature are relatively slow; when the reaction enters the acceleration phase, both temperature and pressure typically rise simultaneously.

[0029] A pressure detector housing 16 is installed on the top of the top cover 5. Inside the pressure detector housing 16 are a pressure sensor 14 and a signal transmission line 15. This allows for real-time and accurate monitoring of pressure changes within the reactor vessel by installing a pressure monitoring device on the top of the vessel body 1. The pressure value is then displayed intuitively on the display screen 18. Operators can adjust reaction conditions promptly based on this information, improving reaction efficiency and product quality. Furthermore, the pressure sensor 14 and signal transmission line 15 are housed within the pressure detector housing 16 on the top of the top cover 5, making them less susceptible to interference from factors such as vigorous stirring of materials within the vessel. This ensures more accurate acquisition of overall pressure data within the reactor vessel, providing precise basic information for subsequent reaction control. The intuitive display of pressure values ​​on the display screen 18 greatly facilitates operation. Alarm 22 can promptly issue an alarm when the pressure is abnormal, and together with safety valve 23, it can effectively ensure the safe operation of the reactor and avoid safety accidents caused by excessive pressure. Alarm 22 is located on the top of the top cover 5, which is convenient for sensing pressure changes. When the pressure is abnormal, it can quickly issue an alarm signal, and the operator can be notified immediately. In the production process of polyaluminum chloride, the reaction conditions are complex and changeable, and the pressure may suddenly rise due to various factors. The rapid response of alarm 22 allows the operator to take timely measures to prevent the pressure from deteriorating further. At the same time, the alarm threshold of alarm 22 can be precisely set according to the design pressure range of the reactor and the actual production needs. This ensures that an alarm will only be issued when the pressure truly deviates from the normal range, avoiding false alarms or missed alarms.

[0030] In summary:

[0031] 1. A pressure detector housing 16 is installed on the top of the top cover 5. The pressure detector housing 16 contains a pressure sensor 14 and a signal transmission line 15. By installing a pressure monitoring device on the top of the reactor body 1, the pressure changes inside the reactor can be monitored in real time and accurately. The pressure value is displayed intuitively on the display screen 18. The operator can adjust the reaction conditions in time to improve reaction efficiency and product quality. At the same time, the pressure sensor 14 and the signal transmission line 15 are not easily affected by factors such as violent stirring of materials inside the reactor. This allows for more accurate acquisition of the overall pressure data inside the reactor, providing accurate basic information for subsequent reaction control. The pressure value can also be displayed intuitively on the display screen 18, which provides great convenience for the operator.

[0032] 2. An alarm 22 is installed on the top of the top cover 5. The alarm 22 can promptly sound an alarm when the pressure is abnormal, effectively ensuring the safe operation of the reactor in conjunction with the safety valve 23 and preventing accidents caused by excessive pressure. The alarm 22 is located on the top of the top cover 5, a convenient position for detecting pressure changes. When an abnormal pressure occurs, it can quickly issue an alarm signal, notifying operators immediately. In the production of polyaluminum chloride, reaction conditions are complex and variable, and the pressure may suddenly rise due to various factors. The rapid response of the alarm 22 allows operators to take timely measures to prevent further pressure deterioration. Furthermore, the alarm threshold of the alarm 22 can be precisely set according to the reactor's design pressure range and actual production needs, ensuring that an alarm is only triggered when the pressure truly deviates from the normal range.

[0033] This avoids false alarms or omissions.
