[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 2 The utility model provides an embodiment of a pretreatment device for processing printing wastewater, comprising a treatment box 1, wherein the treatment box 1 is provided with a device for harmlessly treating the wastewater, wherein the top of the treatment box 1 is fixedly connected with a water inlet pipe 2 for conveying wastewater into the treatment box 1, and the top of the treatment box 1 is fixedly connected with a feeding port 3 for feeding a treatment agent into the treatment box 1, wherein the treatment agent can react chemically with the wastewater, thereby causing the harmful substances in the wastewater to settle and flocculate, so that they can be intercepted by a filter plate 16, and the top of the feeding port 3 is hinged with a box cover 4 for preventing external foreign matter from entering the treatment box 1, and the top of the box cover 4 is fixedly connected with a handle 5 for conveniently opening the box cover 4 by a staff, and a mixing mechanism is arranged inside the treatment box 1, and the mixing mechanism comprises a filter plate 16, which is fixedly installed at the bottom of the treatment box 1 by bolts, and the filter plate 16 can be disassembled and cleaned by screwing the bolts to prevent the filtering capacity of the filter plate 16 from decreasing and affecting the filtering effect, and a cleaning mechanism is arranged above the filter plate 16.

[0031] Reference Figure 2 - Figure 4 The mixing mechanism also includes a motor 6, which is used to provide a driving force. The motor 6 is fixedly installed on the top of the processing box 1. The front end of the output shaft of the motor 6 is fixedly connected to a circular plate 7. The motor 6 drives the circular plate 7 to rotate when it works. A pin 8 arranged in a cylindrical shape is fixedly connected at the non-center of the front side of the circular plate 7. When the motor 6 is working, the movement trajectory of the pin 8 is a circle. The mixing mechanism also includes a slider 9 and a slide groove 10. The inner wall of the slider 9 is rotatably connected to the outer wall of the pin 8. The slider 9 is set to a rectangle. The slider 9 is slidably installed on the inner wall of the slide groove 10. The sliding direction of the slider 9 is left and right sliding. The mixing mechanism also includes a vertical rod 11. The vertical rod 11 rotates It is installed in the center of the bottom of the slide groove 10. When the slider 9 moves to the top of the circular trajectory, the vertical rod 11 moves to the highest point. When the slider 9 moves to the bottom of the circular trajectory, the vertical rod 11 moves to the lowest point. Therefore, when the motor 6 drives the circular plate 7 to rotate, the vertical rod 11 will continuously make linear reciprocating motion in the up and down directions. A spiral lifting groove 12 is provided on the circumferential surface of the vertical rod 11. The vertical rod 11 penetrates and slides on the inner wall of the processing box 1. The vertical rod 11 is slidably connected to the processing box 1 through the spiral lifting groove 12. While making up and down reciprocating motion, the vertical rod 11 will also rotate around its own center line under the action of the spiral lifting groove 12.

[0032] Reference Figure 3 , Figure 4 The mixing mechanism also includes a stirring blade 13, which is fixedly mounted on the circumferential surface of the vertical rod 11. The stirring blade 13 can stir the mixture of wastewater and treatment agent inside the treatment box 1, thereby increasing the reaction speed of harmful substances and treatment agent in the wastewater and improving work efficiency. The mixing mechanism also includes a push plate 14, which is set as a cylinder. The push plate 14 is rotatably mounted on the circumferential surface of the vertical rod 11. The inner wall of the push plate 14 is penetrated and fixedly connected with a solenoid valve 15 for controlling whether the wastewater flows or not. The solenoid valve 15 is initially in a closed state. The push plate 14 is slidably mounted on the inner wall of the treatment box 1. The sliding direction of the push plate 14 is a linear sliding up and down. When the push plate 14 moves, it pushes the wastewater inside the treatment box 1 to oscillate, thereby further increasing the reaction rate. The bottom of the filter plate 16 is fixedly connected with a clean water tank 19. The water inlet at the top of the clean water tank 19 is located below the water outlet at the bottom of the treatment box 1. The bottom of the clean water tank 19 is fixedly connected with a water outlet pipe 20 for discharging the liquid inside the clean water tank 19.

[0033] Reference Figure 3The cleaning mechanism includes a connecting bracket 17, which is arranged in a horizontal state and fixedly installed at the bottom of the vertical rod 11. The movement of the vertical rod 11 drives the connecting bracket 17 to move. The circumferential surface of the connecting bracket 17 is fixedly connected with a brush 18 for cleaning the filter plate 16, thereby reducing the possibility of settled solid harmful substances clogging the filter plate 16 and causing a decrease in the filtering effect.

[0034] Working principle: When in use, waste water is transported to the interior of the treatment box 1 through the water inlet pipe 2, and then the box cover 4 is opened through the handle 5, and an appropriate amount of treatment agent is added to the interior of the treatment box 1, and then the box cover 4 is closed, and the motor 6 is started. The motor 6 drives the circular plate 7 to rotate, and the rotation of the circular plate 7 drives the pin 8 to move. Through the cooperation between the pin 8, the slider 9 and the slide groove 10, the rotation of the circular plate 7 is converted into the reciprocating linear motion of the vertical rod 11. When the vertical rod 11 moves, it will also rotate around its own central axis under the action of the spiral lifting groove 12, thereby driving the stirring blade 13 to move, thereby stirring and mixing the waste water and treatment agent mixture inside the treatment box 1, thereby increasing the reaction rate.

[0035] After a period of time, the harmful substances in the wastewater are reacted, settled and flocculated by the treatment agent, and then the switch of the solenoid valve 15 is turned on. The wastewater enters the bottom of the push plate 14 from the top of the push plate 14 through the solenoid valve 15, and then falls on the filter plate 16 under the push plate 14. The liquid water will fall into the clean water tank 19 below after being filtered by the filter plate 16, and then be taken out through the outlet pipe 20. The settled solid harmful particles will be blocked by the filter plate 16, thereby realizing the harmless treatment of the wastewater.

[0036] When the vertical rod 11 moves, it will also drive the brush 18 on the connecting bracket 17 to continuously move on the surface of the filter plate 16, so as to sweep away the solid particles on the filter plate 16, reducing the possibility of solid sediment blocking the filter plate 16 and causing a decrease in the filtering effect.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
