[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Please refer to the appendix. Figures 1-4 This utility model provides a synthetic reaction apparatus for preparing a water loss reducing agent, including a reaction vessel 1, a feed pipe 2 fixedly connected to one side of the top of the reaction vessel 1, a feed valve 3 fixedly fixed to the body of the feed pipe 2 for adding the material to be prepared as the water loss reducing agent into the reaction vessel 1 through the feed pipe 2, a discharge pipe 4 fixedly connected to the bottom of the reaction vessel 1, a discharge valve 5 fixedly fixed to the body of the discharge pipe 4 for discharging the prepared water loss reducing agent through the discharge pipe 4, and a swing assembly, the reaction vessel 1 fixed on the swing assembly, a stirring assembly fixed inside the reaction vessel 1, a scraping assembly fixed on the stirring assembly for preventing the water loss reducing agent from adhering to the inner wall side of the reaction vessel 1, a first anti-clogging assembly fixed at the bottom of the stirring assembly, a second anti-clogging assembly fixed at the bottom of the reaction vessel 1, and a heating assembly fixed outside the reaction vessel 1; The stirring assembly includes a first reducer 6, which is a transmission device for low speed and high torque. It reduces the speed of the motor by having a gear with fewer teeth on the input shaft mesh with a large gear on the output shaft. The bottom of the first reducer 6 is fixed at the center of the top of the reactor 1. A first servo motor 7 is vertically fixed at the top of the first reducer 6. The output shaft of the first servo motor 7 is fixedly connected to the input shaft of the first reducer 6. The output shaft of the first reducer 6 passes vertically through the center of the top of the reactor 1, and a stirring paddle 8 is fixed to the output shaft of the first reducer 6. Specifically, under the deceleration action of the first reducer 6, when the first servo motor 7 is running, it can drive the stirring paddle 8 to rotate slowly inside the reactor 1, thereby stirring the dehydration agent. The scraping assembly includes a vertically arranged connecting rod 9, which is symmetrically fixed to both ends of the stirring paddle 8. A rubber scraper 10 is fixed to the surface of each connecting rod 9, and the surface of the rubber scraper 10 abuts against the inner wall side of the reactor 1. Specifically, when the first servo motor 7 runs and drives the stirring paddle 8 to rotate slowly, the connecting rod 9 can drive the rubber scraper 10 to rotate slowly and synchronously, thereby continuously scraping the inner wall side of the reactor 1, which can effectively prevent the water loss reducing agent from adhering to the inner wall side of the reactor 1. The first anti-clogging component includes a vertically arranged feeding screw 11. The top end of the feeding screw 11 is fixed to the bottom end of the stirring paddle 8, and the bottom end of the feeding screw 11 extends to the inside of the discharge pipe 4. Specifically, when the first servo motor 7 runs and drives the stirring paddle 8 to rotate slowly, it can also drive the feeding screw 11 to rotate synchronously. Therefore, when the prepared water loss reducing agent is discharged, the operator can open the discharge valve 5 so that the prepared water loss reducing agent is discharged through the discharge pipe 4. During the discharge process, the first servo motor 7 is kept running continuously, so that the feeding screw 11 rotates continuously. The rotating feeding screw 11 can convey the water loss reducing agent downward, thereby effectively preventing clogging during the discharge of the water loss reducing agent. The second anti-clogging component includes a vertically arranged end plate 12, the top of which is fixed to the bottom of the reactor 1, and a pneumatic hammer 13 is horizontally fixed to the side of the end plate 12. A hammer head 14 is fixed to the output shaft of the pneumatic hammer 13. The hammer head 14 can abut against the surface of the feed pipe 4. Specifically, when the pneumatic hammer 13 is running, it can drive the hammer head 14 to strike the feed pipe 4, causing the feed pipe 4 to vibrate, thereby effectively preventing the water loss reducing agent from clogging during the feeding process through the feed pipe 4. It should be noted that a pneumatic impact hammer is a device that uses compressed air as a power source to convert gas energy into impact force through a mechanical structure. Its working principle involves a combination of gas dynamics and mechanical transmission. It drives a piston to generate high-frequency impact through periodic gas flow. The power source consists of a compressed air system. Compressed air enters the pneumatic impact hammer through a pipeline. The pressure range is usually set between 0.4-0.7 MPa. The air inlet is equipped with a one-way valve to ensure unidirectional airflow. The filter assembly is responsible for removing moisture and impurities from the gas. The pressure regulating valve allows the operator to adjust the air pressure intensity according to the actual working conditions. The pressure gauge displays the current air pressure value in real time. The cylinder assembly includes a precision-machined cylinder body and piston. The inner wall of the cylinder is hardened to reduce friction loss. The piston is made of aluminum alloy or alloy steel and chrome-plated to improve wear resistance. The piston rod is connected to the impact head through threads, and an anti-loosening device is installed at the connection. When compressed air enters the front chamber of the cylinder, it pushes the piston to move backward. At this time, the exhaust valve opens to discharge the gas in the rear chamber, forming a unidirectional motion trajectory. The solenoid directional valve of the control system is a key component. It adopts a two-position five-way structure. The coil voltage is usually DC24V or AC220V. When the solenoid valve is energized, the airflow direction is switched so that compressed air enters the rear chamber of the cylinder, pushing the piston forward at high speed. The limit switch or pressure sensor monitors the piston position and the timing accuracy of the triggering reversing signal is controlled within 0.1 seconds to ensure that the impact frequency is stable within the range of 60-120 times / minute. The heating assembly includes an electric heating jacket 15, which is fixed outside the reactor 1. Several electric heating wires 16 are fixed inside the electric heating jacket 15. Specifically, when the electric heating wires 16 are running, they can generate heat energy, thereby heating the water loss reducing agent. When used in conjunction with the stirring paddle 8, the heating effect can be effectively improved. It should be noted that a temperature sensor is fixed inside the reactor 1 to monitor the heating temperature of the dehydration agent in real time. By sending a signal to the controller, the electric heating wire 16 is controlled to operate and shut down, thereby achieving the temperature control function. The oscillating assembly includes two vertically arranged support frames 17, which are symmetrically arranged on both sides of the reactor 1. A second reducer 18 and a second servo motor 19 are fixed to the top of either support frame 17. The output shaft of the second servo motor 19 is fixedly connected to the input shaft of the second reducer 18. A bearing seat 20 is fixed to the top of the other support frame 17. A first fixed frame 21 is rotatably mounted on the bearing seat 20. A second fixed frame 22 is fixed to the end of the output shaft of the second reducer 18. The first fixed frame 21 and the second fixed frame 22 are symmetrically fixed to both sides of the reactor 1. Specifically, under the deceleration action of the second reducer 18, when the second servo motor 19 is running, the reactor 1 can be driven to oscillate through the first fixed frame 21 and the second fixed frame 22. Combined with the stirring function of the stirring paddle 8, the stirring effect of the water loss reducing agent can be effectively improved.

[0020] It should be noted that the device is electrically connected to an external controller and 220V AC mains power, and the controller can be an existing technology device such as a computer for control.

[0021] The usage process of this utility model is as follows: The operator adds the material to be prepared as the water loss reducing agent into the reaction vessel 1 through the feed pipe 2, and then starts the first servo motor 7, the second servo motor 19, and the electric heating wire 16. When the electric heating wire 16 runs, it can generate heat energy, thereby heating the water loss reducing agent. Under the deceleration action of the first reducer 6, when the first servo motor 7 runs, it can drive the stirring paddle 8 to rotate slowly in the reaction vessel 1, thereby stirring the water loss reducing agent. In addition, the stirring of the stirring paddle 8 can effectively improve the heating effect. Under the deceleration action of the second reducer 18, when the second servo motor 19 runs, it can drive the reaction vessel 1 to swing through the first fixed frame 21 and the second fixed frame 22. In conjunction with the stirring function of the stirring paddle 8, the stirring effect of the water loss reducing agent can be effectively improved. Furthermore, when the first servo motor 7 drives the stirring paddle 8 to rotate slowly, the connecting rod 9 can drive the rubber scraper 10 to rotate slowly in sync, thereby continuously scraping the inner wall side of the reactor 1, which can effectively prevent the water loss reducing agent from adhering to the inner wall side of the reactor 1. When the prepared water loss reducing agent is fed, the operator can open the feeding valve 5 and the pneumatic hammer 13 to feed the prepared water loss reducing agent through the feeding pipe 4. During the feeding process, the first servo motor 7 is kept running, so that the feeding screw 11 is rotated continuously. The rotating feeding screw 11 can convey the water loss reducing agent downward, thereby effectively preventing blockage during the feeding process. When the pneumatic hammer 13 is running, it can drive the hammer head 14 to strike the feeding pipe 4, causing the feeding pipe 4 to vibrate, which can again effectively prevent blockage during the feeding process of the water loss reducing agent through the feeding pipe 4.

[0022] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
