DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] First embodiment:

[0029] See also Figures 1 to 7The present invention provides a wastewater treatment device for foaming dried tofu processing, comprising a filter frame 101 and a pretreatment box 102. A rotating shaft 103 is provided at one end of the filter frame 101, and worm gears 104 are provided at both ends of the rotating shaft 103. A plurality of lifting hydraulic cylinders 105 are provided on the outside of the pretreatment box 102, and a C-shaped frame 106 is provided at the output end of the plurality of lifting hydraulic cylinders 105. Support blocks 107 are provided on both sides of the C-shaped frame 106. A mounting box 108 is provided on the support block 107. A worm 109 is provided for rotation in 108, and one end of the worm 109 is provided with a driven bevel gear 110. A linkage rod 111 is provided for rotation at one end of the C-shaped frame 106, and the linkage rod 111 is driven by a motor 112. Both ends of the linkage rod 111 are provided with an active bevel gear 113, and the active bevel gear 113 is meshed with the driven bevel gear 110 and is located in the installation box 108. The pre-treatment box 102 has a treatment tank 114, and the filter frame 101 is rotated by the rotating rod The filter frame 101 is hinged to the corresponding support block 107 and is located between the two support blocks 107. The filter frame 101 also extends into the processing tank 114 and abuts against the C-shaped frame 106. The worm 109 is engaged with the worm gear 104, and the worm gear 104 extends into the installation box 108. The filter frame 101 and the C-shaped frame 106 are first lifted up by the lifting hydraulic cylinder 105, and then the linkage rod 111 is driven to rotate by the motor 112, and then the driving bevel gear 113 is driven to rotate. The transmission of the driven bevel gear 110 causes the worm 109 to rotate, and the worm 109 then drives the worm wheel 104 and the rotating shaft 103 to rotate, and finally the filter frame 101 is rotated to a state convenient for removing impurities. This design allows the filter frame 101 to fully contact the impurities in the wastewater when salvaging impurities, and can be easily lifted out of the wastewater after salvaging is completed, avoiding the problem of impurities floating in the wastewater and being difficult to salvage quickly, greatly improving the salvage efficiency, and enhancing the effect and speed of wastewater pretreatment.

[0030] Among them, a supporting bracket 115 is provided on one side of the pretreatment box 102, and a water inlet pipe 116 is provided on the supporting bracket 115. A telescopic pipe 117 is provided on the water inlet pipe 116, and the telescopic pipe 117 extends to the top of the filter frame 101 and the pretreatment box 102. A water outlet pipe 118 is provided on the other side of the pretreatment box 102, and a control valve 119 is provided on both the water inlet pipe 116 and the water outlet pipe 118. The water inlet pipe 116 and the water outlet pipe 118 provide a convenient water inlet and water outlet control method for the wastewater treatment device. The telescopic pipe 117 extends to the top of the filter frame 101 and the pretreatment box 102, and the position and range of the water inlet can be flexibly adjusted according to actual needs.

[0031] Secondly, the outlet pipe 118 of the pretreatment box 102 is connected to the oil separation end 120, the outlet end of the oil separation end 120 is connected to the air flotation end 121, the outlet end of the air flotation end 121 is connected to the anaerobic end 122, the outlet end of the anaerobic end 122 is connected to the aerobic end 123, and the outlet end of the aerobic end 123 is connected to the sedimentation end 124. By sequentially connecting the outlet pipe 118 of the pretreatment box 102 to the oil separation end 120, the air flotation end 121, the anaerobic end 122, the aerobic end 123 and the sedimentation end 124, a sedimentation end 124 is formed. The invention provides a complete wastewater treatment process. The oil separator 120 can effectively remove grease from the wastewater. The flotation end 121 can further remove suspended matter and tiny particles in the wastewater. The anaerobic end 122 and the aerobic end 123 decompose and transform organic matter in the wastewater through the action of microorganisms. The sedimentation end 124 further precipitates impurities in the treated wastewater, thereby comprehensively purifying the wastewater. This multi-stage treatment method greatly improves the effect of wastewater treatment, enables the treated wastewater to meet higher emission standards, and reduces pollution to the environment.

[0032] When using the wastewater treatment device for processing foamed dried tofu of the present embodiment, wastewater enters the treatment tank 114 of the pretreatment box 102 through the water inlet pipe 116 and the telescopic pipe 117. At this time, impurities in the wastewater will be intercepted by the filter frame 101. When it is necessary to clean the impurities on the filter frame 101, the lifting hydraulic cylinder 105 is started to lift the C-shaped frame 106 and the filter frame 101 and separate them from the treatment tank 114. Then, the motor 112 is started to drive the linkage rod 111 to rotate. The active bevel gears 113 at both ends of the linkage rod 111 rotate accordingly. The active bevel gear 113 meshes with the driven bevel gear 110, thereby driving the worm 109. The worm 109 is engaged with the worm wheel 104 to rotate the rotating shaft 103, thereby rotating the filter frame 101 around the rotating shaft 103 to a suitable angle, and the impurities in the filter frame 101 are discharged uniformly, avoiding the situation where the impurities are difficult to quickly salvage due to their erratic movement in the wastewater; the wastewater after preliminary treatment by the filter frame 101 flows out from the outlet pipe 118 of the pretreatment box 102, and sequentially enters the oil separation end 120 to remove grease, the flotation end 121 to remove suspended matter, the anaerobic end 122 and the aerobic end 123 to decompose organic matter through microorganisms, and the precipitation end 124 to precipitate impurities, finally completing the multi-stage purification treatment of the wastewater from the processing of foamed dried tofu.
