A valve 35 is provided on the powder interface 34, and the valve 35 of the valve 35 The valve core is embedded in the powder interface 34. The mixing barrel 31 can be used for pre-mixing of powder auxiliary materials. Since the raw materials that have been stirred in the tank body 20 are heated when some powder auxiliary materials are added, if such auxiliary materials directly enter the heated mixed materials, they will directly agglomerate, thereby reducing the mixing uniformity and stirring quality overtime. Therefore, the powder auxiliary materials are first added to the mixing barrel 31 through the powder interface 34, and then the low-temperature liquid reagent or water can be added to the mixing barrel 31 through the liquid interface 32 to mix with the powder auxiliary materials. In this way, the powder auxiliary materials that cannot be mixed by heat can be mixed by the low-temperature liquid or water, and then dispersed and sent to the tank body 20 for mixing and stirring to ensure the uniformity of the raw material mixing.

[0034] A discharge interface 37 is provided on one side of the lower end of the mixing barrel 31. The connection position of the discharge interface 37 and the mixing barrel 31 is fixed by welding.

[0036] The heating mechanism 4 includes a heating plate 40, which is an arc-shaped structure. There are two groups of heating plates 40, which are symmetrically distributed on the outer wall of the tank body 20. The inner arc surface of the heating plate 40 is fitted with the surface of the tank body 20. A plurality of electric heating tubes 41 are embedded in the interior of the heating plate 40. The arc lengths of the plurality of electric heating tubes 41 are distributed between the electric heating tubes 41. The electric heating tubes 41 and the heating plate 40 are fixed by screws. A thermostat 42 is installed in the middle of the outer arc surface of the heating plate 40. The plurality of electric heating tubes 41 on a single heating plate 40 are connected in parallel with the same thermostat 42. The electric heating tubes 41 are fixed to the heating plate 40 by screws. The thermostat 42 (temperature controller) is a device for controlling the temperature of the electric heating tube 41. Its main function is to maintain the set temperature by adjusting the on / off state of the electric heating tube 41. The constant temperature heating of the electric heating tube 41 can ensure that the raw materials in the tank body 20 are heated and stirred, and avoid excessively low temperature, which leads to poor stirring and fusion of certain raw materials. A pad 48 is provided at the lower end of the outer wall of the tank body 20. One end of the pad 48 is welded to the surface of the tank body 20. The pad 48 is located at the lower end of the heating plate 40, and the two are closely arranged. The pad 48 can play an auxiliary supporting role for the heating plate 40.

One side of the threaded sleeve 46 is tightly arranged with the end face of the built-in sleeve 44 at the corresponding position, and a knob 47 is distributed on the outer ring wall of the threaded sleeve 46. One end of the knob 47 is welded and fixed to the surface of the threaded sleeve 46. The screw 45 is an elongated bolt structure. By connecting it to one side of the two heating plates 40, and then cooperating with the mutual threaded connection of the threaded sleeve 46 and the screw 45, the two heating plates 40 can be stably wrapped around the outside of the tank body 20, heating the tank body 20, so that the raw materials can be heated and stirred.

[0038] When implementing

[0039] When the raw materials need to be stirred, the raw materials to be mixed can be transported into the tank body 20 through the feed interface 27. Then, the motor 2003 drives the rotating shaft 1 to move in conjunction with the stirring shaft 1 2002. As a result, the stirring blade structure in the form of a grid composed of the connecting rod 2004 and the stirring bar 2006 on the stirring shaft 1 2002 can mix the transported materials. When the motor 1 2003 stirs, the rotating shaft 1 rotates forward, causing the spiral piece 2007 to generate an upward spiral. The conveying force ensures the mixing power at the bottom of the raw material mixing. The scraper 2005 connected by the connecting rod 2004 can contact the inner wall of the tank body 20 and scrape the inner wall of the tank body 20 to prevent the raw materials from adhering to the inner wall of the tank body 20 when the mixture is relatively viscous. When discharging, the rotating shaft of the motor 2003 is turned over, so that the stirring shaft 2002 and the spiral blade 2007 generate a downward spiral conveying force, thereby ensuring the stable discharge of the material from the discharge interface 22.

[0040] When it is necessary to transport the premix of powder auxiliary materials, first add the powder auxiliary materials into the mixing barrel 31 through the powder interface 34, and then add the low-temperature liquid reagent or clean water into the mixing barrel 31 through the liquid interface 32, and mix it with the powder auxiliary materials. Thus, the powder auxiliary materials that cannot be mixed by heat can be mixed with the low-temperature liquid or clean water, and then dispersed and sent into the tank body 20 for mixing and stirring to ensure the uniformity of the raw material mixing. When stirring the materials in the mixing barrel 31, the power supply of the second motor 3004 is turned on, and the second motor 3004 can drive the second rotating shaft to rotate, so that it can drive the second stirring shaft 3002 to rotate, thereby realizing the rotation of the stirring paddle 3005, and the stirring paddle 3005 can turn the materials in the mixing barrel 31, thereby premixing the powder auxiliary materials and the low-temperature solution, and avoiding the situation of agglomeration when directly pouring into the heated mixture;

[0041] When heating and stirring are required in the tank body 20, the thermostat 42 is connected to an external power supply so that it can be used as a temperature adjustment switch of the electric heating tube 41. By adjusting the temperature of the electric heating tube 41, the electric heating tube 41 can be heated at a constant temperature, so that the electric heating tube 41 can heat the heating plate 40, thereby realizing thermal conductive heating of the tank body 20. When the heating plate 40 needs to be installed, the two heating plates 40 are first covered on the surface of the tank body 20 and auxiliary supported by the pad 48. Then, the screw 45 of the extension mechanism is passed through the built-in sleeve 44 embedded in the two extension plates 43 distributed on the same side. Then, the threaded sleeve 46 is threadedly connected to one end of the screw 45 to achieve locking and positioning of the two heating plates 40. The threaded sleeve 46 can be manually operated by the knob 47.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention. These modifications and improvements should also be considered within the scope of protection of the present invention and will not affect the effectiveness and practicality of the present invention.
