[0013] Beneficial effects of the present invention: 1. In the present invention, an outer shell and an inner shell are provided, and an outer cooling tube and an inner cooling tube are adapted and installed in the outer shell and the inner shell, the inner cooling tube and the outer cooling tube are connected, and connected to the liquid inlet pipe and the liquid outlet pipe on the outside, a controller is installed to control the stirring motor, and the stirring member of the stirring motor is adapted to the inner cooling chamber and the outer cooling chamber separated by the inner shell and the outer shell, and the inner stirring blade and the outer stirring blade are installed. When in use, the stirring member synchronously mixes and stirs the inner cooling chamber and the outer cooling chamber, and the inner cooling tube and the outer cooling tube cool down the slurry in the device at the same time, and the effect is that through the cooperation of double-layer stirring and double-layer cooling, the slurry inside the device can be cooled more quickly and evenly at each layer, so that the temperature of the slurry can be kept uniform when discharging, and the effect of stably controlling the discharging temperature to be constant is achieved; 2.

When in use, the temperature difference of each temperature measuring point can be used to estimate the expected cooling effect of the existing coolant on each layer of slurry, so that the coolant intake is adjusted in real time according to the temperature change when the slurry reaches each temperature measuring point to ensure that the target temperature control temperature is stably reached when the slurry is discharged. The effect is that each thermometer is not only used for temperature measurement, but also realizes pre-regulation of the slurry temperature by cooperating with the electric control valve to control the coolant intake. The difference between multi-layer and multi-point temperature measurement and single-point temperature measurement is that although the liquid intake control after single-point temperature measurement can regulate the subsequent slurry discharge temperature, the slurry near the temperature measuring point will cause the discharge temperature to differ from the target temperature due to the sudden change of the coolant intake. The sudden discharge temperature causes the device to control the overall temperature of the slurry inaccurately. In summary, since the discharge temperature of the device is uniform and the temperature is adjusted layer by layer, leaving time for pre-temperature adjustment, the discharge temperature value can be accurately controlled. Therefore, the device forms an integrated solution for discharge temperature control by maintaining the uniformity and accuracy of the discharge temperature, thereby realizing the stable control function of the discharge temperature.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 4 As shown, a feed cooling device convenient for temperature control comprises an outer shell 1, an outer cooling pipe 2 is installed inside the outer shell 1, a cover 3 is installed at the top of the outer shell 1, an inner shell 4 is installed in the middle of the bottom surface of the cover 3, an inner cooling pipe 5 is installed inside the inner shell 4, the outer cooling pipe 2 and the inner cooling pipe 5 are connected at the upper part of the outer shell 1, a liquid inlet pipe 6 is installed on one side of the outer cooling pipe 2, an electric control valve 7 is installed on one side of the liquid inlet pipe 6, a stirring motor 8 is installed in the middle of the top of the cover 3, a stirring member 9 is installed at the output end of the stirring motor 8, and the stirring member 9 includes two inner A stirring blade 10, a thermometer 11 and a thermometer 2 12 are installed on both sides of the top of the cover body 3, and the temperature measuring depths of the thermometer 11 and the thermometer 2 12 are different. A feed port 13 is installed on one side of the top of the cover body 3, and the inner cooling pipe 5 extends to the outside of the outer shell 1 and is connected to the liquid outlet pipe 14. A discharge pipe 15 is installed at the bottom of the outer shell 1, and a pump body 16 is installed on one side of the discharge pipe 15. A thermometer 3 17 is installed on one side of the pump body 16. A controller 18 is installed on one side of the top of the cover body 3; the controller 18 is used to display the temperature of each measuring point and adjust the liquid inlet speed of the electric control valve 7; It should be noted that the vertical cross-section in the center of the outer shell 1 is U-shaped, and the arc-shaped structure at the bottom of its interior is an independent discharge chamber, which is connected to the discharge pipe 15; the electric control valve 7 is an electronic valve, which can control the liquid inlet speed of the liquid inlet pipe 6 connected thereto through an electrical signal. Compared with the traditional manual valve, it can quantitatively control the liquid inlet amount when regulating the liquid inlet speed, and has higher accuracy in flow rate regulation; the stirring motor 8 specifically includes a motor and a reducer installed at the output end of the motor, and the stirring element 9 is installed at the output end of the reducer. The speed of the stirring motor 8 is stably controlled by the reducer to adapt to the speed required for stirring; the three thermometers are all electronic temperature measuring devices; the pump body 16 is preferably a screw pump, which is a rotor-type positive displacement pump, which relies on the volume change of the sealed cavity formed by the screw and the bushing to suck in and discharge the conveyed material. Since its stator is made of elastic material, it is suitable for conveying high-viscosity fluids.

[0019] A display screen 19 and a knob 20 are provided on one side of the controller 18, and the electric control valve 7, the stirring motor 8, the thermometer 1 11, the thermometer 2 12, the pump body 16 and the thermometer 3 17 are all electrically connected to the controller 18; It should be noted that the display screen 19 is used to display the measured temperature of each thermometer in real time, and the buttons at the bottom are used to control the opening and closing status of the electric control valve 7, the stirring motor 8, the pump body 16 and its own state. The knob 20 arranged on the side is used to control the opening and closing degree of the electric control valve 7 to control the liquid inlet speed of the coolant. Preferably, a three-color warning stick is arranged on the top to remind that the device is in working condition and improve the safety of the device operation.

[0020] like Figure 3 and Figure 4 As shown, inner cavities are provided in both the outer shell 1 and the inner shell 4, the outer cooling pipe 2 is clamped inside the inner cavity of the outer shell 1, and the inner cooling pipe 5 is clamped inside the inner cavity of the inner shell 4. That is, by providing inner cavities inside the outer shell 1 and the inner shell 4, the inner and outer cooling pipes are installed in a hidden manner, which ensures the cooling effect while avoiding the influence on the stirring cooling process.

[0021] The outer cooling tube 2 and the inner cooling tube 5 are arranged in the same manner. The tubes are arranged in a ring horizontally and are continuously bent in the vertical direction, that is, they traverse the vertical annular surface along the annular direction of the inner cavity of the shell, thereby ensuring comprehensive cooling of the internal space of the device and avoiding omission of cooling positions.

[0022] The liquid inlet pipe 6 passes through the outer side of the outer shell 1 and is connected to one end of the bottom of the outer cooling pipe 2. The end of the outer cooling pipe 2 away from the liquid inlet pipe 6 passes through the inner side of the outer shell 1 and is connected to the pipe 1 21. The pipe 1 21 passes through the outer side of the inner shell 4 and is connected to one end of the top of the inner cooling pipe 5. The end of the top of the inner cooling pipe 5 away from the pipe 1 21 is connected to the pipe 2 22. The pipe 2 22 passes through the inner shell 4 and the outer shell 1 in sequence and is connected to the liquid outlet pipe 14. It should be noted that the first pipe 21 is used to connect the outer cooling pipe 2 and the inner cooling pipe 5, so that the inner and outer cooling pipes are connected as one, and receive the coolant input by the liquid inlet pipe 6. The second pipe 22 is in the form of an arc pipe connected to a straight pipe, which is used to communicate with the external liquid outlet pipe 14, thereby realizing an integrated double-layer cooling of the internal space of the device; Furthermore, the outer diameter of the inner shell 4 is 50% of the outer diameter of the outer shell 1. The ratio between the outer diameter of the inner shell 4 and the outer diameter of the outer shell 1 is related to the uniformity of the temperature of the slurry after stirring. When the outer diameter of the inner shell 4 is too small, there is still an annular part between the outer side of the inner cooling tube 5 and the outer side of the outer cooling tube 2, which is not easy to be cooled. When the outer diameter of the inner shell 4 is too large, the outer cooling tube 2 and the inner cooling tube 5 are close to each other, and the center position of the inner side of the inner cooling tube 5 is also not easy to cool. Therefore, the inner shell 4 should be centered or centered to the outside. At this time, the inner cooling tube 5 and the outer cooling tube 2 cooperate with each other to quickly cool down the inside and outside of the slurry, thereby improving the cooling speed and uniformity during cooling.

[0023] An outer cold cavity 23 is provided between the inner side of the outer shell 1 and the outer side of the inner shell 4, an inner cold cavity 24 is provided inside the inner shell 4, a temperature measuring rod 1 25 is installed at the bottom of the thermometer 11, a temperature measuring rod 26 is installed at the bottom of the thermometer 2 12, and temperature sensors are built into the bottom ends of the temperature measuring rod 1 25 and the temperature measuring rod 2 26, and both extend through the cover 3 to the inside of the outer cold cavity 23. In addition, the thermometer 11 includes but is not limited to being installed in the outer cold cavity 23, and can also extend to the inner cold cavity 24 near the inner side of the inner shell 4, without interfering with the mixing rotation of the inner stirring blade 10; The stirring member 9 also includes a stirring shaft 27 connected to the stirring motor 8, two inner stirring blades 10 are located in the middle of the stirring shaft 27, and an outer stirring blade 28 is installed on the bottom surface of the stirring shaft 27. The inner stirring blade 10 and the outer stirring blade 28 are evenly installed with five oblique stirring blades along the circumference of the stirring shaft 27. The stirring blade end of the inner stirring blade 10 is close to the inner side of the inner shell 4, and the stirring blade end of the outer stirring blade 28 is close to the inner side of the outer shell 1 and is located below the inner shell 4. It should be noted that after the slurry is injected into the device from the feed port 13 until it is full, the feed port 13 is closed, and then the coolant is injected into the liquid inlet pipe 6. The coolant passes through the outer cooling pipe 2 and the inner cooling pipe 5 in turn and is discharged from the liquid outlet pipe 14 to cool the slurry inside the device. At the same time, the stirring motor 8 is started by the controller 18 to mix the internal slurry. During the mixing process, the inner stirring blades 10 on the inner side of the inner shell 4 mix the slurry located in the inner shell 4, and the outer stirring blades 28 located at the bottom of the stirring member 9 mix the entire slurry. Through the internal and external stirring and turning in conjunction with the double-layer cooling pipe, the slurry can be quickly and evenly cooled, and then falls into the bottom of the inner cavity of the outer shell 1. The slurry is discharged from the arc space at the top of the discharge pipe 15, and the pump body 16 provides the slurry pumping power during discharge. In this process, the temperature of the feed layer is measured by the thermometer 11, the temperature of the middle layer of the slurry is measured by the thermometer 12, and the temperature of the slurry during discharge after cooling is measured by the thermometer 3 17. That is, the three temperature measuring points measure the temperature values ​​of each stage in the cooling process, and cooperate with the controller 18 to realize the real-time measurement of the temperature of each stage in the cooling process. The controller 18 cooperates with the electric control valve 7 to adjust the inlet speed of the coolant, and the inlet amount of the coolant can be adjusted in time according to the temperature changes at each point to achieve the function of accurately controlling the discharge temperature.

[0024] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
