[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0030] See also Figures 1-4 The cleaning mechanism 6 that stirs 5 is fixed on the top of stirring mechanism 5, and the cleaning mechanism 6 that stirs 5 is fixed on the bottom of stirring mechanism 5 is fixed on the top of stirring mechanism 5.

[0031] like Figure 1 As shown, the processing box 1 includes an outer shell 11 fixedly connected to a plurality of support columns 2, an openable and closable sealing cover 12 is provided at the upper end of the outer shell 11, a support frame 13 is fixedly installed inside the outer shell 11, a plurality of filter screens 14 are fixedly installed on the support frame 13, a waste trough 15 is fixedly installed at the bottom end of the outer shell 11, and a discharge mechanism 3 includes a discharge pipe 31 fixedly installed on the outside of the outer shell 11, a control valve 32 is fixedly installed on the discharge pipe 31, and the control valve 32 can smoothly flow out the fully stirred liquid inside the device from the discharge pipe 31, and the multiple filter screens 14 on the inner wall of the processing box 1 can filter impurities to prevent the impurities from flowing out with the fully stirred liquid after stirring. The openable and closable sealing cover 12 is used to pour the liquid into the interior of the processing box 1, and the waste trough 15 is used to collect impurities generated by the final chemical reaction.

[0032] like Figure 2As shown, the transmission mechanism 4 includes a transmission box 41 fixedly mounted on one side of the outer wall of the shell 11, a transmission column 42 is slidably connected inside the transmission box 41, a lead screw 43 is rotatably connected inside the transmission column 42, a moving block 44 is fixedly connected to the bottom end of the transmission column 42, a ball nut seat matching the lead screw 43 is installed on the moving block 44, and a driving motor 45 for driving the lead screw 43 to rotate is installed at the bottom of the transmission box 41. When the driving motor 45 starts running, the moving block 44 fixedly connected to the transmission column 42 can slide up and down along the lead screw 43, so that the transmission column 42 inside the transmission box 41 can move up and down, thereby opening the sealing cover 12 fixedly connected to the output end.

[0033] like Figure 3 As shown, the stirring mechanism 5 includes a driving motor 2 52 fixed to the top of the inner side of the sealing cover 12, and the bottom end of the driving motor 2 52 is fixedly connected to a rotary column 51, and the driving motor 2 52 is used to drive the rotary column 51 to rotate, and the bottom end of the rotary column 51 is fixedly connected to a rotary rod 53, and the outer side of the rotary rod 53 is fixedly connected to a stirring frame 54, and the cleaning mechanism 6 includes a central shaft 61 fixedly connected to the bottom of the rotary rod 53, and a plurality of support rods 62 are fixedly connected to the outer side of the central shaft 61. The other end of the plurality of support rods 62 is fixedly connected to a fixing ring 63, and the outer side of the fixing ring 63 is fixedly connected to a plurality of groups of brushes 64. The driving motor 2 52 drives the rotary column 51 to rotate, thereby rotating the stirring frame 54 on the rotary rod 53, thereby achieving the effect of stirring the liquid. After the fully stirred liquid flows out of the device, the output end of the transmission mechanism 4 is fixedly connected to the sealing cover 12, so that the cleaning mechanism 6 at the bottom moves up and down repeatedly, thereby achieving the effect of cleaning the multiple filter screens 14 on the inner wall.

[0034] like Figure 4 As shown, the rotating mechanism 7 includes a base 71 rotatably connected to the top center of the waste trough 15, and chucks 72 are fixedly installed on both sides of the base 71. The outer sides of the two chucks 72 are fixedly connected to rotating shafts 73. The outer side of the waste trough 15 is installed with a driving motor three 74 for driving the corresponding rotating shaft 73 to rotate. The collecting mechanism 8 includes a waste pipe 81 fixedly connected to the bottom of the waste trough 15, and a control valve two 82 is fixedly installed on the waste pipe 81. After cleaning the impurities on the multiple filter screens 14 on the inner wall of the device, the impurities will fall onto the base 71, and then the rotating shaft 73 is driven to rotate by the driving motor three 74, so that the base 71 is flipped over so that the impurities fall into the inside of the waste trough 15, and finally the impurities are discharged along the waste pipe 81 through the control valve two 82. The whole device achieves the effect of automatic cleaning.

[0035] When the utility model is in use, the sealing cover 12 is first opened by the transmission mechanism 4 to pour in the unstirred liquid, and then the sealing cover 12 is closed to allow the entire stirring mechanism 5 to operate. When the liquid inside the processing box 1 is fully stirred, the liquid will flow out from the discharging mechanism 3. After the fully stirred liquid has completely flowed out, the transmission mechanism 4 starts to move upward to pull out the sealing cover 12 together. At the same time, the stirring mechanism 5 and the cleaning mechanism 6 below the sealing cover 12 will also move vertically upward. When the cleaning mechanism 6 moves upward to the top of the processing box 1, it stops and then moves downward to the bottom of the processing box 1. After multiple reciprocating motions, the impurities on the inner wall filter 14 of the processing box 1 will be completely cleaned off. At this time, the transmission mechanism 4 moves downward to allow the sealing cover 12 to cover the outer shell 11. The cleaned impurities will then fall into the base 71 of the rotating mechanism 7 and are poured into the waste trough 15 through rotation. Finally, the impurities are smoothly discharged along the waste pipe 81 through the control valve 2 82. The entire device achieves the effect of automatic cleaning, thereby further improving the processing efficiency.
