[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] The papermaking wastewater pretreatment device, such as Figures 1-4 As shown, the device includes a main body 1, which comprises a processing box 2, a pressing assembly 3, a first cleaning assembly 4, and a second cleaning assembly 5. A top cover 6 is detachably connected to the top of the processing box 2, allowing collection of the pressed waste material by removing the top cover 6. An inlet 7 is provided on the top cover 6, through which wastewater from papermaking enters. A water outlet pipe 10 is fixedly connected to the bottom of the processing box 2, communicating with the interior of the processing box 2. Filtered wastewater flows through the water outlet pipe 10 to the outside for collection and reuse. A fixing plate 8 is fixedly connected to the side wall of the processing box 2, and the pressing assembly 3 is fixedly connected to the fixing plate 8. A filter screen 9 is fixedly connected to the middle of the processing box 2. The filter screen 9... Two fixed brackets 91 are fixedly connected. The fixed brackets 91 can strengthen the filter screen 9, making it less prone to deformation and avoiding affecting the filtration effect. The filter screen 9 has multiple horizontal and vertical through holes 92 that are interconnected. The through holes 92 are connected to the pores of the filter screen 9. A part of the first cleaning component 4 is fixedly connected to the bottom of the filter screen 9. The second cleaning component 5 is fixedly connected to the bottom of the extrusion component 3. The second cleaning component 5 is mainly used to cooperate with the first cleaning component 4 to clean the filter screen 9, so as to avoid the pores of the filter screen 9 becoming clogged after long-term use, resulting in poor filtration effect. When the filter screen 9 needs to be cleaned, the second cleaning component 5 is activated first, followed by the first cleaning component 4.

[0019] like Figures 1-4As shown, the first cleaning component 4 includes a fan 41 and a ventilation duct 42. The fan 41 is fixedly connected to the ventilation duct 42, which includes a first ventilation duct 421, a second ventilation duct 422, and a third ventilation duct 423. There are two second ventilation ducts 422, each fixedly connected to the lower part of the mounting bracket 91. The first ventilation duct 421 connects the fan 41 to the second ventilation duct 422. There are multiple third ventilation ducts 423, which are fixedly connected to the upper part of the second ventilation duct 422. Each third ventilation duct 423 has an air outlet 424. The mounting bracket... A through groove 93 is opened on 91, which is connected to a through hole 92. A ventilation pipe 423 is inserted into the through groove 93 and its air outlet 424 is opposite to the through hole 92. The through hole 92 is close to the bottom of the filter screen 9. With the cooperation of the second cleaning component 5, after the fan 41 is turned on, the air blows out from the air outlet 424 on the ventilation pipe 42. The air outlet 424 corresponds to the through hole 92. Since the through hole 92 and the through groove 93 are close to the bottom of the filter screen 9, the air blows upward from the bottom of the filter screen 9 to blow out the residual waste paper in the filter screen 9. The squeezing component 3 then scrapes it away and cleans it.

[0020] like Figures 1-4 As shown, the second cleaning component 5 includes a motor 51, a gear 52, and a baffle 53. The motor 51 is fixedly connected to the side wall of the treatment box 2, and the drive end of the motor 51 is fixedly connected to the gear 52. The baffle 53 has a toothed groove 54, and the gear 52 meshes with the toothed groove 54. When the motor 51 starts, it drives the gear 52 to rotate, thereby pushing the baffle 53 under the filter screen 9 and covering the bottom of the filter screen 9. The toothed groove 54 has opposing sliding grooves on both sides, and each sliding groove is slidably connected to the ventilation pipe 422. The squeezing component 3 includes an electric push rod 31 and a pressure plate 32. One end of the electric push rod 31 passes through the side wall of the treatment box 2 and is fixedly connected to the pressure plate 32. The bottom surface of the pressure plate 32 is in contact with the upper surface of the filter screen 9. The squeezing component 3 can effectively compact the waste in the wastewater through the electric push rod 31 and the pressure plate 32. The process removes moisture, separating waste material from wastewater. A slider 81 is fixedly connected to the bottom of the fixed plate 8, and the slider 81 is slidably connected to the chute. The slider 81 is positioned opposite to the second ventilation pipe 422, and the opening of the second ventilation pipe 422 is aligned with the opening of the chute. Thus, the chute can slide along the slider 81 to the second ventilation pipe 422. The auxiliary gear 52 smoothly moves the baffle 53 to below the filter screen 9. The length of the baffle 53 is greater than the length of the filter screen 9, so that the baffle 53 can completely block the bottom of the filter screen 9, ensuring that the air blown out of the air outlet 424 only blows out from the top of the filter screen 9. This automated cleaning process requires no manual intervention, reducing the tediousness of manually cleaning the filter screen 9, improving cleaning efficiency and quality, enabling the device to adapt to the needs of long-term continuous industrial production, and further improving the overall efficiency of papermaking wastewater pretreatment.

All technical solutions falling within the scope of this utility model's concept are protected.
