Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection equipment, and in particular to an industrial wastewater recovery and treatment device and a treatment process thereof. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to the wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater is of various types and has complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains lead, cadmium and other metals, electroplating industrial wastewater contains cyanide and chromium and other heavy metals, petroleum refining industrial wastewater contains phenol, pesticide manufacturing industrial wastewater contains various pesticides, etc. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Therefore, it is necessary to develop and utilize it comprehensively, turning harm into benefit, and taking appropriate purification measures according to the composition and concentration of pollutants in the wastewater before it can be discharged. Industrial wastewater recycling and treatment equipment includes microfiltration. Microfiltration is a solid-liquid separation equipment widely used in the pretreatment and deep treatment of various industrial wastewaters. These industrial wastewaters usually contain impurities such as suspended matter, particulate matter, and colloids. Microfiltration can effectively remove these impurities and improve the cleanliness of the wastewater.

[0003] When the existing microfiltration machine is in use, generally, a backwash system is used to impact the surface of the filter cartridge or filter screen, so that impurities attached to the inner wall of the filter cartridge or filter screen are separated from the inner wall. However, most of the impurities will flow downward along the inner wall of the filter cartridge or filter screen and mix in the wastewater waiting to be filtered. Only a small part of the impurities will fall into the sewage trough in the center of the filter cartridge or filter screen. The sewage discharge efficiency is very low, which reduces the filtration efficiency of the microfiltration machine. The impurities are mixed in a part of the wastewater that can be filtered out, causing certain losses. Moreover, the water column sprayed by the backwash system often sprays only at a specific position of the filter cartridge or filter screen, and the range is small, so that the backwashing efficiency is low. The inventor proposes an industrial wastewater recovery and treatment device and a treatment process thereof to solve the above problems. Summary of the Invention

[0027] A treatment process for an industrial wastewater recovery and treatment device comprises the following steps: S1: First, the industrial wastewater is microfiltered and discharged into the microfiltration box 1 through the fixed pipe 207, thereby completing the microfiltration operation of the industrial wastewater; S2: Further backwashing the microfilter 202, by driving the third connecting shaft 613 to rotate back and forth via the first connecting shaft 606, thereby driving the third liquid delivery tube 505 and the nozzle 507 to swing, thereby further improving the backwashing efficiency; S3: receiving and filtering the wastewater mixed with impurities washed down from the water source S2, and sending the wastewater mixed with impurities into the filter housing 401 through the receiving box 302 and the first conduit 301, thereby completing the filtration of the wastewater containing impurities; S4: Collect the impurity solids remaining in the filter housing 401. The screw 406 rotates to drive the extrusion ring 409 to move, scraping the impurity solids attached to the filter housing 401. The rotating disk 416 rotates to push the impurity solids into the waste box 417, thereby collecting the impurity solids. Working principle: When it is necessary to use the microfiltration equipment to recycle and treat industrial wastewater, the first step is to perform microfiltration on the industrial wastewater. The industrial wastewater waiting for microfiltration is pumped into the fixed pipe 207 through the second pump body. The industrial wastewater flows through the fixed pipe 207, the intermediate ring 206 and the liquid inlet pipe 204, and enters between the first fixed disk 203 and the second fixed disk and inside the rotating cylinder 201. The industrial wastewater then flows through the microfiltration mesh 202 and enters the microfiltration box 1, thereby completing the microfiltration operation of the industrial wastewater. In the second step, the microfilter 202 is backwashed. While the first step is being carried out, the first motor 601 is started to rotate, driving the first connecting shaft 606 to rotate. Through the transmission action of the second synchronous belt and the second synchronous wheel, the rotating block 609 is driven to rotate with the second connecting shaft 608 as the axis, thereby driving the sliding rod 610 and the moving ring 611 to move back and forth along the surface of the guide rod 616, thereby driving the guide rod 616, the swing block 615 and the fixed sleeve 614 to rotate with the third connecting shaft 613 as the axis, thereby driving the third connecting shaft 613 to reciprocate by a set angle. The fourth connecting shaft 504 connected thereto is driven to rotate back and forth through the transmission action of the fourth synchronous belt and the fourth synchronous wheel, thereby driving all the fourth connecting shafts 504 to rotate back and forth, thereby driving the third liquid delivery pipe 505 and the nozzle 507 to swing back and forth with the fourth connecting shaft 504 as the axis. The first pump body pumps external water into the first liquid delivery pipe 501, and then flows through the second liquid delivery pipe 502 and the hose 506 into the third liquid delivery pipe 505, and then is sprayed out from the nozzle 507. The water column sprayed by the nozzle 507 swings back and forth, thereby further improving the backwashing efficiency; The third step is to receive and filter the wastewater mixed with impurities washed down by the water source in the second step. When the first connecting shaft 606 rotates, it drives the second spur gear 607 to rotate with the first connecting shaft 606 as the axis, and then drives the third spur gear 205 to rotate with the transmission shaft 208 as the axis, and then drives the first fixed disk 203, the second fixed disk, the rotating cylinder 201 and the microfiltration screen 202 to rotate with the transmission shaft 208 as the axis, and then drives multiple receiving mechanisms 3 to rotate in the clockwise direction. When the first special-shaped gear 307 corresponding to the receiving mechanism 3 rotates along the inner wall of the second special-shaped gear 702 until it is engaged with the arc-shaped rack 704, it drives the first special-shaped gear 307 and the cover plate 306 to rotate a set angle with the first rotating shaft 305 as the axis, and then drives the cover plate 306 to leave the top of the receiving box 302, so that the receiving box 302 is in an open position. In this state, the wastewater mixed with impurities flowing downward along the inner wall of the rotating cylinder 201 and the micro-filter 202 continuously enters the receiving box 302, and the wastewater flows along the bottom of the receiving box 302 to the first conduit 301, and then enters the filter housing 401 through the second conduit 303. The wastewater containing impurities is discharged from the filter housing 401 through the filter screen 402, while the impurities are left on the inner wall of the filter housing 401, thereby completing the filtration of the wastewater containing impurities. When the first special-shaped gear 307 corresponding to the receiving mechanism 3 rotates along the inner wall of the second special-shaped gear 702 until it meshes with the teeth on the inner wall of the second special-shaped gear 702, it drives the first special-shaped gear 307 to reverse, causing the cover plate 306 to reverse and re-cover the top of the receiving box 302, so that the wastewater mixed with impurities in the receiving box 302 falls back into the rotating cylinder 201; The fourth step is to collect the impurity solids retained in the filter housing 401, turn off all electrical appliances in the microfiltration machine, and then start the double-headed motor 405 to rotate, drive the screw 406 to rotate, and then drive the movable disk 408 and the extrusion ring 409 to move along the inner wall of the filter housing 401, so that the extrusion ring 409 moves, scrapes off the impurity solids attached to the filter housing 401, and pushes the impurity solids to the side of the rotating disk 416, then reverse the double-headed motor 405 to return to its original position, and then start the second motor 411 to rotate a set number of circles, drive the second rotating shaft 412 and the third rotating shaft 413 to rotate, and then drive the fourth rotating shaft 415 to rotate, and then drive the two rotating disks 416 to rotate a set number of circles around the second rotating shaft 412 and the fourth rotating shaft 415 respectively. The rotating disk 416 rotates to push the impurity solids located on the side of the rotating disk 416 into the waste box 417, thereby collecting the impurity solids.
