Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid treatment, and specifically to an industrial organic waste liquid recovery and treatment method and device thereof. Background Technique

[0002] Liquid waste containing a large amount of organic pollutants generated during industrial production processes. These waste liquids usually originate from multiple industries, including but not limited to chemical industry, pharmaceutical industry, food processing, printing and dyeing, paper making, petroleum refining, etc. Due to their complex composition, high toxicity, high concentration, and poor biodegradability, if these waste liquids are directly discharged without proper treatment, it will lead to a series of environmental problems such as water eutrophication, water quality deterioration, and biological death. In order to reduce the impact of wastewater on the environment, a series of treatment and purification measures are usually carried out on the wastewater to ensure the reduction of pollutant concentration, thereby reducing the potential harm to water bodies, soil, and ecosystems. However, there are still certain deficiencies in the existing wastewater treatment technologies and methods when in use.

[0003] An industrial organic wastewater integrated treatment device with the publication number CN205687712U, which connects the water inlet of the photocatalytic chamber through a main water pipe. A water pump is provided on the main water pipe. Multiple ultraviolet lamps, photocatalyst carriers, and baffles are provided in the photocatalytic chamber. The ultraviolet lamps, photocatalyst carriers, and baffles correspond to each other to form an "S"-shaped channel. The lower end of the photocatalytic chamber is also provided with a water outlet. The process is simple, easy to install and maintain, and has a small floor area and good purification effect. However, the device requires a longer time to treat wastewater to achieve the expected treatment effect, which in turn leads to a reduction in treatment efficiency, especially more obvious when treating a large amount of wastewater or high-concentration wastewater.

[0004] Therefore, an industrial organic waste liquid recovery and treatment method and device thereof are proposed to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide an industrial organic waste liquid recovery and treatment method and device thereof to solve the problem in the above background technique that the devices on the current market cannot achieve the expected treatment effect when treating wastewater, resulting in a reduction in treatment efficiency.

In the collection tank, adjust the temperature according to the characteristics of the waste liquid, and use a stirring device to stir the waste liquid in the collection tank at a low speed. After stirring is completed, preliminarily filter the waste liquid through a filter screen, and convey the obtained filtrate to a temporary storage tank through a pipeline;

[0008] S2: Transfer the waste liquid in the temporary storage tank to the neutralization tank.

While the moving member 21 is moving, it drives the cross bar 22 to move, so that the cross bar 22 slides along the guide groove 12. Since the guide groove 12 is arranged in a wavy line structure, the cross bar 22 moves up and down reciprocally during the lateral reciprocating movement. At this time, the cross bar 22 drives the linkage rod 23 to move synchronously, so that the linkage rod 23 drives the fixed cylinder 24, the diversion pipe 26, the stirring blades 27 and the disc 28 to move synchronously. Further, when the fixed cylinder 24, the diversion pipe 26, the stirring blades 27 and the disc 28 move synchronously, the pump 14 is turned on. The pump 14 sucks the solution in the U-shaped water tank 15 and transports it to the fixed cylinder 24 through a hose, so that the solvent impacts the impeller 25, thereby driving the impeller 25 to rotate, so that the impeller 25 drives the diversion pipe 26 and the stirring blades 27 to rotate synchronously to stir the wastewater. Then, the solution in the fixed cylinder 24 enters the diversion pipe 26, so that the solution flows into the disc 28 along the diversion pipe 26 and is finally ejected from the water outlet hole 29 to be mixed with the wastewater;

[0072] During the movement of the cross plate 9, it drives the vertical plate 3004 to move, so that the vertical plate 3004 drives the moving rod 3007 and the clamping block 3010 to move synchronously. Further, the clamping block 3010 extends into the clamping groove 3012. At this time, the double-shaft motor 16 and the pump 14 are turned off, and at the same time, the micro motor 32 is turned on. The micro motor 32 drives the fixed cylinder 24 to rotate, so that the fixed cylinder 24 drives the diversion pipe 26, the stirring blades 27 and the disc 28 to rotate synchronously. Then, the disc 28 presses against the contact plate 3003, so that the contact plate 3003 drives the elastic telescopic rod 3002 to slide along the inner wall of the fixed frame 13, thereby squeezing the first airbag 3001, so that the first airbag 3001 contracts, and the gas in the first airbag 3001 is transported to the second airbag 3009 through a pipeline, so that the second airbag 3009 expands, thereby pushing the sliding sleeve 3015 to slide along the moving rod 3007 and the vertical plate 3004. And when the sliding sleeve 3015 is moving, it squeezes the compression spring 3013 to contract. At the same time, the convex block 3006 slides along the spiral groove 3008, thereby driving the moving rod 3007 to rotate, so that the moving rod 3007 drives the clamping block 3010 to rotate, and further makes the clamping block 3010 engage with the clamping groove 3012;

[0073] After the precipitation chamber 2 has been stationary for a period of time, the double-shaft motor 16 is started at this time, so that the double-shaft motor 16 drives the stirring rod 17 and the reciprocating lead screw 18 to reverse. The reciprocating lead screw 18 will drive the gear 19 to reverse, causing the gear 19 to engage with the rack 20, driving the cross plate 9 to move in the reverse direction. At this time, the clamping block 3010 will pull the scraper 3011 to slide along the inner wall of the precipitation chamber 2, thereby driving the sediment at the bottom of the precipitation chamber 2 to move. During the movement, the upper clear liquid will flow through the liquid leakage holes on the scraper 3011 to the other end of the scraper 3011. At this time, the opening on the sealing plate 33 is opened, and the upper clear liquid will flow into the filtration chamber 3 through the opening and the communication groove 4;

[0074] Through the setting of the elastic telescopic rod 3002 and the abutting plate 3003, during the rotation of the reciprocating lead screw 18, the disc 28 will slide on the surface of the abutting plate 3003. And during the up and down movement of the disc 28, the elastic telescopic rod 3002 will contract when being squeezed and automatically reset after the squeezing force disappears, so that the elastic force of the elastic telescopic rod 3002 always squeezes the first airbag 3001;

[0075] After the sediment in the precipitation chamber 2 is gathered in one place, the micro motor 32 is controlled to rotate at this time, so that the disc 28 is separated from the abutting plate 3003. At this time, the abutting plate 3003 will slide downward under the action of gravity. Immediately afterwards, the sliding sleeve 3015 will reset and move under the elastic force of the compression spring 3013, so that the sliding sleeve 3015 drives the convex block 3006 to move along the spiral groove 3008 while driving the moving rod 3007 to reverse, thereby releasing the clamping connection between the clamping block 3010 and the clamping groove 3012, so that the scraper 3011 resets and moves under the elastic force of the tension spring 3014, scraping off the waste water remaining on the inner surface of the precipitation chamber 2, avoiding waste water residue and improving the precipitation efficiency. Through the setting of the buffer rubber 34, the damage caused by the hard impact of the scraper 3011 can be prevented;

[0076] Further, when the drive motor 3101 is turned on, the drive motor 3101 will drive the pulley 3110 to rotate, causing the pulley 3110 to drive the belt 3107 to rotate. The belt 3107 will drive the pulley 3110 on the second conveying roller 3103 to rotate, thereby driving the second conveying roller 3103 to rotate. The second conveying roller 3103 drives the mesh conveyor belt 3104 to rotate, and then, through the mesh holes on the mesh conveyor belt 3104, the wastewater discharged from the communication groove 4 is filtered for the second time. The mesh conveyor belt 3104 drives the trapezoidal block 3105 to move synchronously. When the trapezoidal block 3105 fits with the knocking block 3111, the knocking block 3111 is squeezed, causing the knocking block 3111 to drive the connecting plate 3109 to rotate. When the trapezoidal block 3105 separates from the knocking block 3111, the connecting plate 3109 will rotate back under the drive of the torsion spring, thereby knocking on the mesh conveyor belt 3104 to shake off the impurities attached to the mesh conveyor belt 3104. At the same time, the brush 3112 will slide along the surface of the mesh conveyor belt 3104 to further clean the mesh conveyor belt 3104.
