Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, and in particular to a method and system for harmlessly disposing and recycling high-salt hazardous waste. Background Art

[0002] High-salt hazardous waste refers to hazardous waste with high salinity, which mainly comes from electroplating, sewage treatment, metallurgy, leather manufacturing, textile and other industries.

[0003] High-salt hazardous waste water treatment equipment is a professional treatment equipment designed for wastewater with high salt content and containing hazardous waste. This type of equipment usually adopts a variety of advanced technologies, such as evaporation process, membrane separation technology, biological treatment technology, etc., to effectively treat high-salt wastewater to achieve solid-liquid separation, desalination, water purification and other goals. At the same time, these equipment must also have the ability to treat hazardous waste to ensure that harmful substances in the wastewater are properly handled and will not cause harm to the environment and human health.

[0004] At present, when using the high-salt hazardous waste water treatment pool on the market, the waste water needs to be concentrated in the pool for treatment. When the waste water is discharged into the treatment pool, larger suspended matter will adhere to the grid, causing the grid to be blocked.

[0028] A method for harmlessly disposing and recycling high-salt hazardous waste, comprising the following steps: S1. First, connect the water pipe 3 to the high-salinity hazardous wastewater discharge pipe outside, so that the wastewater can be discharged from the water pipe 3 into the sedimentation tank 33. At the same time, the wastewater will drive the impeller 37 to rotate, so that the runner 30 can drive the connecting rod 31 to reciprocate; S2. Afterwards, the connecting rod 31 is rotatably connected to the first rack 29, so that when the rotating wheel 30 rotates, the connecting rod 31 can drive the temporary storage chamber 28 to move. When the temporary storage chamber 28 moves, the second gear 24 can be driven to move on the second rack 35, so that the cam 23 can press the contact rod 22 and the sealing plug 27 to move downward, so that the sealing plug 27 can be removed from the bottom end of the supporting frame 26, and the chemical agent inside the temporary storage chamber 28 can flow into the sedimentation tank 33, completing the work of evenly placing the chemical agent; S3. Finally, when the impeller 37 is rotating, it can drive the fourth gear 36 and the first gear 16 to rotate simultaneously, so that the winding wheel 18 can pull the scraper 11 to move to the rear end through the connecting rope 15, so that the scraper 11 can push the larger suspended matter accumulated at the bottom end of the grille 8 to the interior of the centralized cavity 6 for unified collection, thereby completing the isolation treatment of high-salt hazardous waste water.

[0029] The working principle of Example 1 is as follows: when in use, the water pipe 3 is first connected to the external discharge equipment, so that the high-salt hazardous wastewater can be discharged from the water pipe 3 into the interior of the sedimentation tank 33. At the same time, the front end of the impeller 37 is vertically aligned with the water pipe 3, so that when the water pipe 3 discharges wastewater, the impeller 37 can be driven to rotate, and when the impeller 37 rotates, the fourth gear 36 and the runner 30 can be driven to rotate at the same time. When the runner 30 rotates, the connecting rod 31 can be driven to move back and forth. When the connecting rod 31 moves back and forth, the first rack 29 in front of the side end of the sedimentation tank 33 can be driven to move, and when the first rack 29 moves, the temporary storage chamber 28 can be driven to move at the same time. Two are arranged on the sedimentation tank 33 through the discharge device 19, and the two first racks 29 are respectively connected to the third rack 29. The top and bottom ends of the wheel 32 are meshed, so that when the first rack 29 at the front end of the sedimentation tank 33 drives the third gear 32 to rotate, the first rack 29 at the rear side end of the sedimentation tank 33 can be driven to move simultaneously, so that the two temporary storage chambers 28 can be moved simultaneously. When the temporary storage chamber 28 is displaced, the second gear 24 can be driven to move on the second rack 35, so that the second gear 24 can drive the cam 23 to rotate. When the raised part of the cam 23 rotates to contact the contact rod 22, the sealed rubber plug 27 can be squeezed to move downward, so that the sealed rubber plug 27 can penetrate the inner bottom end of the supporting base frame 26 and the temporary storage chamber 28, so that the chemical agent inside the temporary storage chamber 28 can be discharged through the temporary storage chamber 28 and the circular hole at the bottom end of the supporting base frame 26, and the chemical agent inside the temporary storage chamber 28 can be discharged through the temporary storage chamber 28 and the circular hole at the bottom end of the supporting base frame 26. The temporary storage chamber 28 is vertically aligned with the interior of the sedimentation tank 33, so that the chemical agent can flow into the wastewater inside the sedimentation tank 33, so that the chemical agent can be integrated into the wastewater. At the same time, when the temporary storage chamber 28 is displaced, the cam 23 can be driven to circulate through the contact rod 22. When the cam 23 passes through the contact rod 22, the elasticity of the second spring 21 will drive the sealed rubber plug 27 to reset upward, so that the sealed rubber plug 27 can enter the temporary storage chamber 28 and the circular hole inside the support frame 26 again, so that excessive outflow of the chemical agent can be avoided. When the temporary storage chamber 28 is displaced, the cam 23 can be driven to reciprocate through the contact rod 22, so that multiple discharges of the chemical agent can be performed. In addition, when the chemical agent is added, the temporary storage chamber 28 is in a moving state, so that the chemical agent The agent can be evenly delivered to different areas inside the sedimentation tank 33 to complete the work of evenly delivering the chemical agent. At the same time, when the fourth gear 36 rotates, it can drive the first gear 16 to rotate, and when the first gear 16 rotates, the reel 18 can pull the scraper 11 to move to the rear end through the connecting rope 15, and the bottom end of the scraper 11 is attached to the inner bottom end of the grille 8, so that the scraper 11 can push the impurities accumulated on the grille 8 when it moves. When the fourth gear 36 rotates 270°, the reel 18 pulls the connecting rope 15 to drive the scraper 11 to move to the rear end to the limit position, and when the scraper 11 moves to the rear end to the limit position, the convex rod 10 can squeeze the blocking side plate 12 away from the grille 8, so that the rear end of the grille 8 can be opened.It is convenient for the scraper 11 to push the impurities off the grille 8 when it moves to the rear end to the limit position. At this time, the impurities can fall into the interior of the concentration chamber 6 for collection, so as to prevent the impurities from falling into the interior of the sedimentation tank 33. Subsequently, when the fourth gear 36 rotates 270°, the first gear 16 loses meshing with the fourth gear 36, and the grille 8 is inclined at 30°, so that the scraper 11 can slide and reset along the first guide rail 9 to the front end. The scraper 11 is slidably sleeved on the first guide rail 9, so that the scraper 11 can be supported to move in a straight line. When the scraper 11 moves to reset When the scraper 11 moves forward, the convex rod 10 at the front end of the scraper 11 can be driven to squeeze the blocking side plate 12 at the front end of the grille 8 away from the grille 8, so that the scraper 11 can push the impurities again, so that the scraper 11 can push the impurities when it moves forward and backward. When a certain amount of impurities accumulate in the concentrated cavity 6, the concentrated cavity 6 can be pulled to the end away from the grille 8, so that the concentrated cavity 6 can be taken out, which is convenient for dumping the impurities. Then, the plug plate 7 is inserted into the inside of the sleeve frame 17, so that the concentrated cavity 6 can be installed again, which is convenient for the concentrated cavity 6 to receive the fallen impurities again and complete the work.

[0030] Embodiment 2, on the basis of embodiment 1, as Figure 8 As shown, the support base 26 also includes a lower edge bracket 38 and a stirring rod 39. The lower edge bracket 38 is symmetrically fixedly installed at the bottom end of the support base 26, and the stirring rod 39 is equidistantly fixedly installed on the outer side of the lower edge bracket 38.

[0031] When implementing this embodiment, when the temporary storage chamber 28 is displaced, the stirring rod 39 can be driven to displace inside the sedimentation tank 33 at the same time, so that the stirring rod 39 can stir the wastewater inside the sedimentation tank 33, thereby improving the fusion efficiency of the wastewater and the chemical agent. At the same time, the stirring rod 39 is located inside the sedimentation tank 33, and the stirring rod 39 is spaced 50 cm from the bottom end of the sedimentation tank 33, so that the stirring rod 39 can be prevented from getting stuck on the bottom and the work can be completed.
