[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.
[0020] like Figure 1 and 2As shown, a double-wall corrugated pipe production mixing device includes a mixing shell 1 and a separation cylinder 2. The separation cylinder 2 is arranged in the middle of the inner side of the mixing shell 1. The separation cylinder 2 divides the interior of the mixing shell 1 into an inner circulation channel 4 and an outer circulation channel 5. The inner circulation channel 4 and the outer circulation channel 5 are connected. A circulation structure 7 is provided on the inner side of the mixing shell 1 to allow the raw materials to circulate inside the inner circulation channel 4 and the outer circulation channel 5.
[0021] According to the above structure, when mixing, the granular material and the reinforcing material are put into the interior of the mixing shell 1, and the material is driven to flow through the circulation structure 7. The material circulates inside the inner circulation channel 4 and the outer circulation channel 5, thereby improving the smoothness of the material flow and improving the efficiency of material mixing.
[0022] like Figure 1 As shown, the mixing housing 1 includes a shell 11, the top of the shell 11 is fixedly connected to a feed trough 12, one end of the bottom of the shell 11 is fixedly connected to a discharge pipe 13, the discharge pipe 13 is provided with a solenoid valve 14, and the bottom end of the shell 11 is provided with support legs 15 distributed in a rectangular array.
[0023] According to the above structure, when mixing, the material is put into the interior of the housing 11 through the feed trough 12. After the mixing is completed, the material inside the housing 11 is discharged through the discharge pipe 13 by opening the solenoid valve 14.
[0024] like Figure 2 and 3 As shown, the separation cylinder 2 is fixedly connected to one end of the inner wall of the shell 11, a gap is set between one end of the separation cylinder 2 and the other end of the inner wall of the shell 11, and the other end of the separation cylinder 2 is provided with leakage grooves 21 equidistantly distributed around the axis of the separation cylinder 2.
[0025] According to the above structure, during mixing, the materials enter and exit the separation cylinder 2 through the leakage groove 21 .
[0026] like Figure 2 and 4 As shown, the circulation structure 7 includes a forward and reverse motor 71 and a rotating shaft 72. The forward and reverse motor 71 is fixedly connected to one end of the shell 11, and the rotating shaft 72 is rotatably connected to the inside of the shell 11. The output shaft of the forward and reverse motor 71 is fixedly connected to one end of the rotating shaft 72. The outer wall of the rotating shaft 72 is fixedly connected with an inner spiral piece 73, and one end of the outer wall of the rotating shaft 72 is fixedly connected with an outer spiral piece 74. The inner spiral piece 73 is rotatably connected to the inside of the inner circulation channel 4, and the inner spiral piece 73 is rotatably connected to the inside of the outer circulation channel 5. The spiral directions of the inner spiral piece 73 and the outer spiral piece 74 are opposite.
[0027] According to the above structure, when mixing, the shaft 72 is first driven to rotate clockwise by the forward and reverse motor 71. At this time, the inner spiral piece 73 and the outer spiral piece 74 both rotate clockwise with the shaft 72, and the inner spiral piece 73 pushes the material to move to the left in the inner circulation channel 4, and the inner spiral piece 73 pushes the material to move to the right inside the outer circulation channel 5. At this time, the material inside the inner circulation channel 4 flows to the outer circulation channel 5 through the gap between one end of the dividing cylinder 2 and one end of the inner wall of the shell 11, and the material inside the outer circulation channel 5 flows to the inside of the inner circulation channel 4 through the leakage groove 21, thereby forming a forward circulation flow of the material. After 1-2 minutes, the shaft 72 is driven to rotate counterclockwise by the forward and reverse motor 71, and the inner spiral piece 73 and the outer spiral piece 74 cooperate with each other to make the material form a reverse circulation flow.
[0028] The working principle of the present invention is as follows: when mixing, the material is put into the interior of the shell 11 through the feed trough 12, and the rotating shaft 72 is first driven by the forward and reverse motor 71 to rotate clockwise. At this time, the inner spiral piece 73 and the outer spiral piece 74 both rotate clockwise with the rotating shaft 72, and the inner spiral piece 73 pushes the material to move to the left in the inner circulation channel 4, and the inner spiral piece 73 pushes the material to move to the right in the outer circulation channel 5. At this time, the material inside the inner circulation channel 4 flows into the outer circulation channel 5 through the gap between one end of the dividing cylinder 2 and one end of the inner wall of the shell 11, and the material inside the outer circulation channel 5 flows into the interior of the inner circulation channel 4 through the leakage groove 21, thereby forming a forward circulation flow of the material. After 1-2 minutes, the rotating shaft 72 is driven to rotate counterclockwise by the forward and reverse motor 71, and the inner spiral piece 73 and the outer spiral piece 74 cooperate with each other to make the material form a reverse circulation flow. After the mixing is completed, the solenoid valve 14 is opened to discharge the material inside the shell 11 through the discharge pipe 13.
