Example 1: referring to fig. 1-2, a pretreatment device for tanning wastewater comprises a frame 1, a driving roller 7, a driven roller 9, filter cloth 4, a brush 5 and a collecting tank 6, wherein the frame 1 is obliquely arranged at an angle of 20 degrees with the ground, the driving roller 7 is arranged at the oblique upper head end of the frame 1, the driven roller 9 is arranged at the oblique lower tail end of the frame 1, the filter cloth 4 is wound and wrapped on the driving roller 7 and the driven roller 9 to circularly run, and the driving roller 7 is driven by a motor (not shown in the figure) to drive the filter cloth 4 and the driven roller 9 to move together; the hairbrush 5 is arranged at the head end of the rack 1, is arranged in parallel along the width direction of the driving roller 7 and is abutted against the filter cloth 4 on the driving roller 7, the hairbrush 5 is positioned on the side surface of the driving roller 7 and is abutted against the filter cloth 4 in a contact manner, and meanwhile, the rotating speed of the hairbrush 5 is greater than that of the driving roller 7 so as to enhance the rolling brush treatment effect of the hairbrush, in the embodiment, the rotating direction of the hairbrush 5 is anticlockwise, and brushed down fluff moves downwards, so that the fluff is convenient to collect; collecting vat 6 is located brush 5 below, and here collecting vat 6 mainly collects the fine hair that brush 5 brushed down, and collecting vat 6 is close to frame 1 one side height and is equivalent to the frame height, leaves very little gap with frame 1 head end, and its height to the side is higher than the height of brush 5, prevents that the fine hair that brushes down at the in-process of brush 5 clearance from flying out the collecting vat under the effect of rotatory air current, causes the influence to the surrounding environment, and the width of collecting vat 6 is greater than the width of filter cloth 4 simultaneously.

As shown in fig. 3, a deviation correcting device is further arranged at the middle section of the frame 1, and comprises two deviation correcting cylinders 3 and a deviation correcting roller 8, the two deviation correcting cylinders 3 are symmetrically arranged at two sides of the frame 1, the cylinder body of the deviation correcting cylinder 3 is fixedly connected with the frame 1, the end heads of the piston rods of the two deviation correcting cylinders 3 are connected with two ends of the deviation correcting roller 8, the deviation correcting roller 8 is parallel to the driving roller 7 and the driven roller 9, the installation height of the deviation correcting roller 8 is greater than that of the driving roller 7 and that of the driven roller 9, and the highest point of the filter cloth 4 during operation is formed. The arrangement of the rectification roller 8 is used for preventing the filter cloth 4 from deviating in the operation process on one hand, and providing a turning point for the filter cloth 4 on the other hand, so that the filter cloth 4 is clearly divided into a filtering area 41 and a transportation area 42, the area between the rectification roller 8 and the driven roller 9 is the filtering area 41, the area between the rectification roller 8 and the obliquely upper head-end driving roller 7 is the transportation area 42, the filtering area 41 is the area for filtering tanning wastewater, the rectification roller 8 is arranged as the highest point to effectively prevent the wastewater from flowing to the transportation area 42 and influencing the fluff treatment of the hairbrush 5, the transportation area 42 is not directly contacted with the tanning wastewater and only plays a role in transporting the fluff, two pairs of infrared generators 101 and infrared receivers 102 are also arranged in the range of the transportation area 42, the two infrared generators 101 are symmetrically arranged on the upper surface of the frame 1, the two infrared receivers 102 are symmetrically arranged on the lower surface of the frame 1, the filter cloth 4 is arranged between the infrared generator 101 and the infrared receiver 102, and the infrared receiver 102 controls the deviation rectifying cylinder 3. The operation principle of the deviation correcting device is that the height of the deviation correcting cylinders 3 on two sides of the rack 1 is adjusted in advance, the infrared generator 101 and the infrared receiver 102 cannot receive signals due to the fact that the filter cloth 4 is arranged in the middle of the deviation correcting cylinders, at the moment, the deviation correcting cylinders are in a normal operation state, when the filter cloth 4 deviates, the infrared receiver 102 on one side of deviation does not block the filter cloth 4, the infrared signal is received, the piston rod end of the deviation correcting cylinder 3 on the same side is controlled to retract downwards, the piston rod end of the deviation correcting cylinder 3 on the other side of the deviation correcting cylinders extends upwards, the movement distance is set in advance, the deviation correcting rollers 8 are driven to correspondingly incline, the filter cloth 4 continuously moves and deviates under the condition of left-right height difference until the filter cloth 4 returns to the original position again, the infrared signal is shielded, the infrared receiver 102 cannot receive the infrared signal, the deviation correcting cylinders 3 on the two sides return to the normal state again, and the deviation correcting process is completed. And simultaneously, because the utility model provides a tanning wastewater pretreatment device is with tanning waste water slowly pass through in filtering area 41, later to the transportation district 42 and handle, therefore the rotation rate of drive roll 7 is less, guarantees the effect of brush 5, and the last filterable tanning waste water flows out from the device below, gets into subsequent purification process.

Furthermore, baffles 2 are also arranged on two sides of the frame 1 within the range of the filtering area 41 to prevent tanning wastewater from flowing out of the range of the filter cloth 4 to cause environmental pollution.

Further, in order to ensure that the width range of the filter cloth 4 can be processed and fluff collection is facilitated, the width of the brush 5 is larger than that of the filter cloth 4 and smaller than that of the collecting groove 6.

The utility model discloses an operation principle: tanning waste water slowly flows into the filtering area 41 from the upper part of the filter cloth 4, under the action of gravity, water flow flows out from the lower part, suspended matters such as fluff and the like on the surface of the tanning waste water are remained on the filter cloth 4 and reach the position of the brush 5 along with the rotation of the filter cloth 4, the fluff suspended matters on the surface of the filter cloth 4 are brushed down under the action of the brush 5 and fall into a collecting tank below, then the filter cloth 4 continues to carry out circulating filtration, if the filter cloth 4 deviates in the process, the deviation is corrected under the action of the deviation correcting cylinder 3, the deviation correcting roller 8, the infrared generator 101 and the infrared receiver 102, the deviation correcting process is automatic deviation correcting, the operation is simple and fast, and the filtering can be carried out after the deviation correction.
