[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1 and Figure 2 As shown, an embodiment of the MC casting nylon reaction equipment of the utility model includes a mounting platform 1 and a reactor 2. The reactor is fixed on the mounting platform by a rotating support 3. The reactor is also connected to a rotating power mechanism 5. The rotating power mechanism drives the reactor to rotate and discharge materials along the rotation direction defined by the rotating support. A heating furnace 6 is arranged on the mounting platform at the bottom of the reactor. The heating furnace heats the reactor. A vacuum port 7, a feed port 8 and an air inlet 9 are arranged on the top of the reactor to meet the reaction needs. A discharge pipe 10 is also arranged on one side of the reactor surface located at the bottom. The discharge pipe is used to discharge the materials after the reaction is completed. A ball valve 4 is arranged on the discharge pipe, the feed port and the air inlet. The feed port is pumped through an external high-temperature resistant rubber tube. The air inlet is connected to the dryer 17 through a hose to transport dry gas into the reactor.

[0027] Specifically, the above-mentioned rotating power mechanism can adopt an electric telescopic push rod, one end of which is connected to the mounting platform shaft and the other end is connected to the reactor shaft. Through the telescopic action of the telescopic push rod, the reactor can be pushed to rotate and the angle position can be fixed. When in use, the telescopic rod is in a retracted state, driving the reactor to a vertical state. According to the process requirements, the operation is performed through the feed port, the air inlet and the vacuum port. The heating furnace heats the reactor. After the reaction is completed, the telescopic push rod is extended to push the reactor to rotate so that the discharge port of the discharge pipe is at the lowest position. Then, the ball valve on the discharge pipe is opened to discharge the material. After the telescopic push rod is extended, the position of the reactor can be fixed, so no manual support is required, which improves the safety of manual operation.

[0028] In order to reduce the number of connecting pipes on the reactor, the feed port and the air inlet can be connected to the interior of the reactor through a tee, and the on-off effect can be achieved according to the corresponding ball valves.

[0029] Since the reaction conditions inside the reactor could not be observed during the reaction, in order to improve the yield rate, Figure 3As shown, the vacuum port is connected to a plurality of transparent glass buffers 13 arranged in series, the transparent glass buffer at the top is connected to one end of the U-shaped tube 14, the other end of the U-shaped tube is connected to the buffer tank 15, and the buffer tank is connected to the vacuum pump. The two ends of the U-shaped tube are arranged downward, and the distance between the top of the U-shaped tube and the top of the reactor is not less than 1.5m, so as to ensure that the rising liquid level of the material will not enter the U-shaped tube, and the rising liquid level of the material can be observed in the transparent glass buffer, so that the reaction state can be easily grasped. The transparent glass buffer is a glass ball, which is connected to each other by a hose, which is easy to install and has a good sealing effect. Therefore, a protective frame 16 is also arranged on the top of the reactor, and the transparent glass buffer is bonded and arranged in the protective frame to ensure its connection strength and prevent the transparent glass buffer from shaking.

[0030] During the discharge process, the reactor will fall over, so the discharge pipe is arranged to be tilted upward, and a connecting arm 18 is provided between the outer wall of the discharge pipe and the outer wall of the reactor to ensure the connection strength. Subsequently, an avoidance groove 19 for avoiding the discharge pipe is also provided on the mounting platform corresponding to the discharge pipe. After the reactor falls over, the discharge pipe is in a low position, and the discharge pipe will not interfere with the mounting platform, which is convenient for discharge.

[0031] Reference Figure 4 As shown, in order to ensure that the reactor is located at a low position and prevent it from being too high to affect the discharge, an avoidance hole is provided on the installation platform corresponding to the bottom of the reactor, and the heating furnace is arranged below the avoidance hole, that is, the heating furnace can directly heat the reactor, and a heat collecting ring 12 is also provided between the heating furnace and the avoidance hole to avoid excessive heat loss during the heating process.

[0032] The above structure can be automatically controlled by a control cabinet, and the heating furnace can maintain constant temperature heating and automatically control the temperature to avoid inaccurate manual temperature control. The telescopic push rod can maintain a fixed telescopic amount, thereby ensuring the accuracy of the position.

[0033] The above embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in this technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
