Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly relates to a multi-stage treatment device for jade processing wastewater. Background Art

[0002] Jade has two types: soft and hard. Usually, the jade mentioned refers to soft jade, which is one of the most common jewels. In recent years, with the continuous rise in the price of jade, more and more jade processing enterprises have been built, and the output of jade has also increased significantly. A large amount of wastewater is generated in various processing links of jade, such as sawing, polishing, washing, waxing, etc. In order to make these water bodies meet the discharge standards, treatment devices are usually used to treat the wastewater. Most treatment devices perform solid-liquid separation on the wastewater through a filter plate. However, the wastewater contains a large amount of stone powder, residues and other substances, with high turbidity, and it is difficult to be treated by natural sedimentation. Therefore, a liquid medicine is added to mix it evenly with the wastewater to improve the sedimentation effect. However, the sedimented impurities will remain on the filter plate, and may block the filter plate after long-term use, affecting the filtering effect and reducing the treatment efficiency.

Inside the processing tank 1, there is a rotatable first filter plate 21. The first filter plate 21 is located in the upper half of the processing tank 1. Inside the processing tank 1, there is a fixedly connected first rotating seat 211. One end of the first filter plate 21 is rotatably connected to the first rotating seat 211. Symmetrically distributed through slots 212 are opened inside the processing tank 1. The other end of the first filter plate 21 is slidably connected to the through slots 212. The first filter plate 21 is inclined. The first filter plate 21 reciprocating up and down can filter large particle impurities. After opening the solenoid valve, the large particle impurities slide from the export 12 into the storage tank 13.

[0021] Inside the processing tank 1, there is a rotatable first rotating shaft 22. Symmetrically arranged on the first rotating shaft 22 are fixedly connected first cams 221.

The first rotating shaft 22 passes through the shell of the processing tank 1 and is fixedly connected with a first synchronous wheel 222. A fixedly connected motor 223 is installed on the outer wall of the processing tank 1. The output shaft of the motor 223 is fixedly connected to the first rotating shaft 22. When the motor 223 rotates, it drives the first rotating shaft 22 to rotate, and the first cams 221 also reciprocally knock on the bottom of the first filter plate 21, increasing the filtering effect of the first filter plate 21.

Second racks 41 are symmetrically and movably provided inside the processing box 1. First support plates 42 symmetrically distributed are fixedly provided at the tops of the second racks 41. A second support plate 421 fixedly connected and a rotatable fourth rotating shaft 44 are provided between two opposite first support plates 42. The fourth rotating shaft 44 is located below the second support plate 421. A slider 422 fixedly connected and a rotatable fourth gear 442 are provided on the side wall of the first support plate 42. The fourth gear 442 is located below the slider 422. The slider 422 is slidably connected to the chute groove 31. A rotatable fifth rotating shaft 43 is provided inside the processing box 1. Fifth gears 431 fixedly connected are symmetrically provided on the fifth rotating shaft 43. The fifth gears 431 are located below the second racks 41, and the fifth gears 431 are engaged with the second racks 41. When the fifth gears 431 rotate, they drive the second racks 41 to move.

[0027] The fifth rotating shaft 43 passes through the housing of the processing box 1 and is fixedly connected with a fourth synchronous pulley 432. A second synchronous belt 433 is provided between the fourth synchronous pulley 432 and the third synchronous pulley 25 for transmission. When the third synchronous pulley 25 rotates, it drives the fourth synchronous pulley 432 to rotate, and the fifth gears 431 also rotate accordingly. Second cams 441 fixedly connected are symmetrically provided on the fourth rotating shaft 44. The rotating shaft of the fourth gear 442 is fixedly connected to the rotating shaft of the fourth gear 442. The fourth gear 442 is engaged with the first rack 33.

[0028] On the top of the second support plate 421, slidable connecting columns 45 are evenly arranged. On the top of the connecting columns 45, fixedly connected brushes 451 are provided. The number of the brushes 451 is the same as the number of the filter holes of the second filter plate 3. At the bottom of the connecting columns 45, third support plates 452 fixedly connected are also provided at the same time. Between the third support plates 452 and the second support plate 421, fixedly connected springs 453 are provided. The second cam 441 rotates to reciprocally press the third support plates 452, the connecting columns 45 move up and down reciprocally, and the brushes 451 reciprocally pass through the second filter plate 3, so as to clean the filter holes in the second filter plate 3, prevent excessive impurities from blocking the second filter plate 3 and affecting the filtering effect.

[0029] Working principle: During use, the waste water enters the interior of the treatment tank 1 from the feed hopper 11, and the treatment liquid medicine enters the interior of the treatment tank 1 from the connecting pipe 15. The motor 223 is started. The rotation of the motor 223 drives the first rotating shaft 22 to rotate, and the first cam 221 also reciprocally knocks the bottom of the first filter plate 21, driving the first filter plate 21 to move up and down reciprocally. The first filter plate 21 can filter large-particle impurities. After all the waste water is poured in, after the electromagnetic valve is opened, the large-particle impurities slide down from the discharge port 12 into the storage tank 13. The rotation of the first rotating shaft 22 drives the first synchronous pulley 222 to rotate, and the second synchronous pulley 24 also rotates accordingly, driving the first gear 23 to rotate, and the second gear 233 and the third gear 234 also rotate synchronously, driving the stirring blades 235 to rotate continuously, which can promote the uniform mixing of the waste water and the treatment liquid medicine and increase the sedimentation effect. The rotation of the third synchronous pulley 25 drives the fourth synchronous pulley 432 to rotate, and the fifth rotating shaft 43 also rotates accordingly, driving the fifth gear 431 to rotate, and the second rack 41 starts to move accordingly, driving the slider 422 to slide along the sliding groove 31. During the movement of the second rack 41, due to the different gear ratios of the fourth gear 442 and the fifth gear 431, the fourth gear 442 can rotate quickly when encountering the tooth blocks at the bottom of the first rack 33. The second cam 441 rotates to reciprocally press the third support plate 452, driving the connecting column 45 to move up and down reciprocally, and the brush 451 also moves up and down reciprocally through the second filter plate 3, so as to clean the filter holes in the second filter plate 3, prevent excessive impurities from blocking the second filter plate 3 and affecting the filtering effect. When the slider 422 touches the contact sensor 32 in the sliding groove 31, the motor 223 rotates in reverse, and the brush 451 can reciprocally clean the second filter plate 3.

[0030] From the above description, it can be seen that in the above embodiments of the present invention, the first cam 221 reciprocally knocks the bottom of the first filter plate 21, which can increase the filtering effect. The continuous rotation of the stirring blades 235 can promote the uniform mixing of the waste water and the treatment liquid medicine and increase the sedimentation effect. The brush 451 moves up and down reciprocally through the second filter plate 3, which can clean the filter holes in the second filter plate 3, prevent excessive impurities from blocking the second filter plate 3 and reduce the treatment efficiency.

[0031] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
