The annular trash rack 31 is a long annular metal woven net formed by weaving stainless steel metal wires, the mesh opening of the metal woven net is 2mmL multiplied by 1mmW-50mmL multiplied by 50mmW, and the specific mesh opening can be variously selected by matching with the characteristics of industrial wastewater; in addition, the wire diameter of the stainless steel wire for the metal mesh grid is 0.2-5 mm. The metal mesh grid has larger effective pore area than the grid type trash rack, so that the unit area has larger flux for treating more sewage; and the surface strength and toughness of the net surface of the metal woven net are higher than those of the grid bars with rigid structures, so that the metal net has more comprehensive and more effective effect on removing pollutants in water, and has better bearing performance and impact resistance on polluted solids flowing to the net surface along with water flow.
The open end department in both sides of cyclic annular trash rack 31 all sets firmly a drive chain 34, and two fixed gear dish 32 and two fixed gear dish 33 down mesh with drive chain 34 respectively and transmit, because two fixed gear dish fixed connection are on drive pivot 22, drive two fixed gear dish rotations along with the rotation of drive pivot, and then drive two fixed gear dish rotations down to drive the cyclic annular trash rack who meshes with it and realize the continuous gyration of metal mesh face. The surface of the trash rack with the annular structure can continuously rotate and move upwards along with the operation of equipment, the net surface bearing pollutants is slowly moved out of the water surface, the pollutants are drained and cleaned, the net surface of the sewage contact surface can be permanently updated due to the continuous rotation of the annular trash rack, and the long-term effective blocking effect can be achieved.
The net surface of the annular trash rack 31 is provided with a plurality of trash baffles 35 at intervals along the direction crossing the net surface, and the interval distance between two adjacent trash baffles 35 is 200mm-1000 mm. The cross section of the dirt blocking baffle 35 is of an L-shaped structure and is made of L-shaped metal angle steel, one side of the L-shaped metal angle steel is horizontally contacted with the net surface and is tightly locked on the net surface by using bolts, the other side of the L-shaped metal angle steel is vertically erected on the net surface and protrudes out of the net surface by 10mm-30mm, the dirt blocking baffle can be used for stabilizing the blocked dirt on the metal net surface in a regional mode, and the situation that the blocked dirt slides back to a water body due to the upward moving process on the net surface is avoided, so that the dirt blocking failure is caused. The specific connection mode of the dirt blocking baffle 35 is as follows: a plurality of lath-shaped combination pieces 312 are inserted into the inside of the net surface of the annular trash rack 31 at intervals corresponding to the trash baffle 35, threaded connection pieces 313 are arranged on the combination pieces after sequentially penetrating through one side of the trash baffle and the meshes of the annular trash rack, and then the trash baffle is locked on the net surface by the combination pieces.
In order to ensure that the net surface of the annular trash rack can move continuously and the problem of the inclined movement of the metal net does not occur, a plurality of support columns 311 penetrate through the annular trash rack 31 at intervals along the direction crossing the net surface, two ends of each support column are fixedly connected with the transmission chains 34 on the left side and the right side of the annular trash rack respectively, the spacing distance between every two adjacent support columns is set to be 30-100cm, and the transmission chains 34 can be metal chains or plastic chains. In the structure, the support columns penetrate through the annular trash rack, each support column is wrapped inside the net surface by utilizing the weaving structure of the metal weaving net, and the support columns, the metal net surface and the transmission chains at the left end and the right end are stably combined together after being locked and fixed by screws; meanwhile, the problem that the net surface deviates in the circulating operation process can be solved by combining the meshing transmission of the upper and lower fixed gear discs and the transmission chain. Simultaneously, can produce the tensile phenomenon of metal to wire side and drive chain after the operation atress to cause the metal wire side to loosen and link up bad problem with the chain gear, this application can set up portable adjustment tight bearing device on the skeleton, respectively sets up a set ofly about, is favorable to doing drive chain readjustment and urgent processing after a period of operation in the future, lets the metal wire side of operation can better use.
In addition, the inside upstream face and the surface of a water opposite side that are located of both sides of skeleton 1 all set firmly a support rail 14 towards surface of a water opposite side, and drive chain 34 is located support rail and supports on this support rail towards upstream face one side, and this support rail's setting can let drive chain remove according to the preface in the guide rail to reduce the tensile condition of blocking the foreign matter of chain, and can protect this drive chain.
The structure and the setting mode of the dirt wheel brush cleaning component 4 are as follows:
the dirt wheel brush cleaning assembly 4 comprises a rotating wheel brush 42 fixedly arranged on a wheel brush rotating shaft 41, the peripheral surface of the rotating wheel brush is adjustably attached to the upper end of the back water surface of the annular dirt blocking net through a wheel brush distance adjusting device 43, and the rotating direction of the rotating wheel brush is opposite to the running direction of the annular dirt blocking net. The rotating wheel brush 42 is a plastic (PP or PVC) dirt brush, and the length of the rotating wheel brush is the same as the width of the annular dirt blocking net, so that the rotating wheel brush can be in full contact with meshes on a net surface without dead angles when rotating along with the driving rotating shaft.
The continuous rotation of wheel brush axis of rotation in this filth wheel brush cleaning assembly is realized by aforementioned drive assembly structure, and when the speed reducer drove the drive pivot and rotate promptly, drive this wheel brush axis of rotation through the drive pivot and rotate to reach the rotation of cyclic annular trash rack and the rotation of rotating the wheel brush and share a set of actuating mechanism's purpose. In addition, the rotation direction of the rotating wheel brush is opposite to the running direction of the annular trash rack, so that the dirt on the net surface can be cleaned and brushed, and meanwhile, the dirt can be thrown into the dirt storage basket below the splash board behind the trash rack. The cleaning function is designed in a simple physical contact and brush removal mode, the cleaning purpose can be achieved without using a large amount of cleaning water for washing in the process, and the water for cleaning the system can be greatly saved.
The sewage in the water intercepted by the net surface of the annular sewage blocking net under the water body gradually moves to the top end of the sewage blocking grid along with the net surface, the sewage continuously moves along with the net surface at the top end and turns over to the back water surface along with the turning of the net surface and then falls off, and for the sewage which does not fall off or the sewage which is stuck to the metal net surface, the sewage on the metal net surface is scraped and brushed off by utilizing the bristles of the rotary wheel brush on the rotary wheel brush rotary shaft, and the residual sewage on the net surface is moved out. In addition, two sewage guide vanes 15 which are distributed in a mirror symmetry manner are arranged on the back water surface of the framework 1 and positioned on two sides of the annular sewage blocking net, and are used for guiding the brushed sewage.
