Since the lengths of each group of feeding pipes are different and the positions of the discharge ports of the feeding pipes are different, the material entering the feeding pipes is subjected to different centrifugal forces when discharged and falls into different positions in the reaction frame, so that the added material is distributed more evenly, preventing the material from piling up at the same position, and improving the efficiency of material mixing.

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. Example

[0024] A plurality of fixed support seats 3 are provided, and one end of the discharge pipe 6 penetrates through the bottom plate 2 and communicates with the reaction frame 1 .

[0025] One end of the bracket 73 away from the driving motor 71 is fixedly connected to the reaction frame 1, one end of the connecting tube 76 away from the device frame 77 passes through the second gear 75, one end of the feeding tube 78 extends to the outside of the connecting tube 76, and one end of the feeding tube 78 away from the connecting tube 76 passes through the device frame 77 and extends to the inside of the reaction frame 1. The outer side of the connecting tube 76 is rotatably connected to the reaction frame 1 through a sealed bearing, and multiple groups of feeding tubes 78 are provided with different lengths.

[0026] The control device 9 includes a piston tube 91, the inner wall of which is slidably connected to a piston 92 with a rod, the top of which is fixedly connected to a heat conductive plate 93, electric valves 94 are provided on the feeding tube 78 near one side and the top of the inner wall of the device frame 77, a control switch 95 is installed on the inner bottom of the device frame 77 near the piston 92, and electric heating wires 96 are evenly installed on the inner wall of the device frame 77 near the feeding tube 78.

[0027] The control device 9 is provided with multiple groups, the outer side of the piston tube 91 is fixedly connected to the device frame 77 through a support frame, one end of the heat conductive sheet 93 penetrates and extends to the inside of the feeding tube 78, and the end of the heat conductive sheet 93 away from the feeding tube 78 penetrates and extends to the inside of the piston tube 91.

[0028] The control switch 95 is arranged on the control circuit of the electric valve 94 , and the top center position of the control switch 95 is directly opposite to the piston 92 with rod.

[0029] During use, the material is introduced into the reaction frame 1 from the feed port 5 for processing. When it is necessary to add material, the required added material is poured into the feeding tube 78 from the top of the feeding tube 78, and the driving motor 71 is turned on to drive the connecting tube 76 to rotate through the meshing of the first gear 74 and the second gear 75. At this time, the material is thrown from the feeding tube 78 into the reaction frame 1 to mix with the material inside the reaction frame 1. Since each group of feeding tubes 78 has a different length and a different position of the discharge port of the feeding tube 78, the material entering the feeding tube 78 is subjected to different centrifugal forces when discharged and falls into different positions in the reaction frame 1. Through the installation of the feeding device, the material is thrown from the feeding tube into the reaction frame to mix with the material inside the reaction frame. Since each group of feeding tubes has a different length and a different position of the discharge port of the feeding tube, the material entering the feeding tube is subjected to different centrifugal forces when discharged and falls into different positions in the reaction frame, so that the added material is distributed more evenly, preventing the material from accumulating at the same position, and improving the efficiency of material mixing.

[0030] The heating wire 96 is turned on to preheat the material entering the feeding tube 78. When the material in the feeding tube 78 is heated to a certain degree, the heat conducting sheet 93 is heated and transfers the heat to the piston tube 91. Since the piston tube 91 is filled with a heat expansion medium, as the heat increases, the piston 92 with a rod is pushed down by the expansion medium and touches the control switch 95. The control switch 95 opens the electric valve 94, so that the heated material in the device frame 77 is discharged from one end of the feeding tube 78, and then new material enters the feeding tube 78 inside the device frame 77. 8, so that the temperature of the heat conducting sheet 93 is reduced, the piston with rod 92 rises and disengages from the control switch 95, at which time the control switch 95 closes the electric valve 94, and the material in the feeding pipe 78 is heated again. Through the installation of the control device, the heat conducting sheet is heated and the heat is transferred to the piston tube, and the piston with rod is pushed down by the expansion medium and touches the control switch. The electric valve is opened by the control switch, thereby achieving the purpose of controlling the heated material to enter the reaction frame, avoiding the addition of cold material to the hot kettle, so as to avoid internal stress caused by the large temperature difference and affecting the service life of the equipment.

[0031] See also Figure 1-5 The present invention provides a technical solution: on the basis of embodiment 1, a stirring device 10 comprises a stirring column 101, a groove 102 is provided on the outer side of the stirring column 101, a rotating rod 103 is rotatably connected to the inner wall of the groove 102 through a rotating seat, a stirring plate 104 is sleeved on the outer side of the rotating rod 103, a compression spring 105 is installed on one side of the stirring plate 104, an elastic rod 106 penetrates one side of the stirring plate 104, and impact balls 107 are installed at both ends of the elastic rod 106.

[0032] One end of the stirring column 101 is fixedly connected to the stirring rod 8 . Two groups of stirring devices 10 are provided and staggeredly installed. The grooves 102 are opened on both sides of the stirring column 101 .

[0033] One end of the compression spring 105 away from the stirring plate 104 is fixedly connected to the inner wall of the groove 102, and the impact ball 107 is made of metal.

[0034] When in use, the connecting pipe 76 is driven to rotate by the driving motor 71, so that the stirring rod 8 rotates accordingly, and the stirring plate 104 stirs the material inside the reaction frame 1 under the action of centrifugal force. Since the rebound force of the compression spring 105 is opposite to the force of the centrifugal force, the stirring plate 104 is driven to swing. At this time, the elastic rod 106 drives the impact ball 107 to knock on the outside of the stirring column 101. Through the installation of the stirring device, the stirring plate is used to stir the material inside the reaction frame under the action of centrifugal force. Since the rebound force of the compression spring is opposite to the force of the centrifugal force, the stirring plate is driven to swing. At this time, the elastic rod drives the impact ball to knock on the outside of the stirring column, stirring the material and knocking on the stirring column at the same time, thereby achieving the purpose of cleaning the stirring column and effectively improving the stirring efficiency of the device.
