[0019] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Embodiment: Refer to Figures 1 to 7As shown in the figure, the present invention is an integrated chemical wastewater treatment device, including a housing 1. Inside the housing 1, a mixing chamber 2 is fixedly provided. Inside the mixing chamber 2, a driving chamber 3, a stirring chamber 4, and a filtering chamber 5 are provided. Two liquid pipes 6 for flowing chemical wastewater and neutralizing liquid respectively penetrate through the housing 1. Both of the two liquid pipes 6 are communicated with the top of the filtering chamber 5. The filtering chamber 5 is located above the stirring chamber 4 and is communicated with the stirring chamber 4. A first filter screen 7 is provided between the filtering chamber 5 and the stirring chamber 4. A discharge port 8 is opened at the bottom of the stirring chamber 4, which is used to discharge the mixed substances together. A valve 9 is provided on the discharge port 8. This kind of valve 9 is composed of a sealing block and an oil cylinder, which belongs to the common valve 9 structure in the prior art. A discharge port 10 is opened on the side wall of the housing 1, which is convenient for discharging the mixed solid generated by the reaction. Inside the housing 1 and below the discharge port 8, a second filter screen 11 is provided. One end of the second filter screen 11 inclines and extends towards the discharge port 10. Inside the housing 1 and below the second filter screen 11, a liquid discharge port 12 is opened. An observation window 44 for external personnel to observe is also provided on the side wall of the housing 1.

[0021] As Figure 2 shown, a servo motor 13 is embedded on the housing 1. This servo motor 13 is a common driving device in the prior art. The characteristic of this kind of driving device is to rotate reciprocally within a certain range. A driving rod 14 is fixedly provided on the output end of the servo motor 13. The other end of the driving rod 14 extends vertically downward and extends into the driving chamber 3. A connecting rod 15 is fixedly provided on the driving rod 14. One end of the connecting rod 15 extends into the filtering chamber 5. A long strip-shaped through slot is opened between the filtering chamber 5 where the connecting rod 15 passes through and the driving chamber 3, which is convenient for the connecting rod 15 to move reciprocally. A blocking member for blocking the two liquid pipes 6 is provided on the section of the connecting rod 15 extending into the filtering chamber 5. As Figure 3 shown, the blocking member includes a mounting block 16, two blocking balls 17, and two first springs 18. The mounting block 16 is fixedly provided at one end of the connecting rod 15 extending into the filtering chamber 5. Two mounting grooves 19 are opened on the mounting block 16. The two blocking balls 17 are respectively located in the two mounting grooves 19. The two first springs 18 are provided between one of the blocking balls 17 and the bottom of one of the mounting grooves 19. A bearing is connected to each of the blocking balls 17. By setting the bearing, the blocking ball 17 can roll on the top of the filtering chamber 5 along with the movement of the connecting rod 15. One end of the first spring 18 and the bearing are fixedly connected to the bearing, and the other end of the first spring 18 is fixedly connected to the bottom of the mounting groove 19. A through hole 46 communicating with the inside is also opened at the bottom of the mounting groove 19, which is convenient for discharging the liquid existing in the mounting groove 19. By rotating the servo motor 13, the driving rod 14 is driven to rotate, further driving the connecting rod 15 and the mounting block 16 to rotate in the filtering chamber 5. When the blocking ball 17 rolls below the liquid pipe 6, due to the rebound of the first spring 18, the blocking ball 17 is driven to block the liquid pipe 6. The intermittent inflow can effectively improve the mixing effect of the chemical wastewater and the neutralizing liquid.

[0022] As Figure 2 shown, a first cleaning member for cleaning the first filter screen 7 is fixedly provided on a section of the connecting rod 15 extending into the filtering chamber 5. The first cleaning member includes a first fixing rod 20 and a first brush plate 21. The first fixing rod 20 is fixedly arranged on a section of the connecting rod 15 extending into the filtering chamber 5, and the first brush plate 21 is fixedly arranged at the end of the first fixing rod 20 away from the connecting rod 15. The first brush plate 21 is in sliding contact with the top surface of the first filter screen 7. Such a setting can effectively drive the connecting rod 15 to move by the rotation of the driving rod 14, and drive the first brush plate 21 to reciprocally slide on the top surface of the first filter screen 7 through the first fixing rod 20. The bottom of the first brush plate 21 is provided with a cleaning brush, which can clean the first filter screen 7. A cleaning port 45 is opened on one side of the filtering chamber 5, which is convenient for foreign matters to be discharged from the cleaning port 45 to the mixing chamber 2.

[0023] As Figure 2 and Figure 5As shown in the figure, a second cleaning member for driving and cleaning the second filter screen 11 is provided in the driving cavity 3. A first bevel gear 22 is fixedly provided on the driving rod 14. A coaxial shaft rod 23 is rotatably provided at one end of the driving rod 14 away from the steering gear 13. A second bevel gear 24 is fixedly provided on the shaft rod 23. A third bevel gear 25 is provided between the first bevel gear 22 and the second bevel gear 24. Both ends of the third bevel gear 25 are meshed with the first bevel gear 22 and the second bevel gear 24 respectively. With such a setting, when the steering gear 13 rotates, it can effectively drive the driving rod 14 to rotate, and further drive the first bevel gear 22 on the driving rod 14 to rotate. When the first bevel gear 22 rotates, it will drive the third bevel gear 25 and the second bevel gear 24 to rotate. The second cleaning member includes a screw rod 26, a fixed sleeve 27, a second fixing rod 28 and a second brush plate 29. One end of the screw rod 26 is rotatably provided on the side wall of the outer housing 1, and the other end of the screw rod 26 is fixedly passed through the axis of the third bevel gear 25. The fixed sleeve 27 is threadedly sleeved on the screw rod 26. A guide rod 30 parallel to the screw rod 26 is further provided in the outer housing 1. The fixed sleeve 27 is slidably sleeved on the guide rod 30. One end of the second fixing rod 28 is fixedly provided at the bottom of the fixed sleeve 27, and the other end of the second fixing rod 28 extends towards the second filter screen 11. The second brush plate 29 is slidably provided at the end of the second fixing rod 28 away from the fixed sleeve 27. The second brush plate 29 is slidably abutted against the top surface of the second filter screen 11. The rotation of the third bevel gear 25 can effectively drive the screw rod 26 to rotate on the outer housing 1, and drive the fixed sleeve 27 to move on the screw rod 26 and the guide rod 30. Through the movement of the fixed sleeve 27, the second fixing rod 28 drives the second brush plate 29 to slide along the top of the second filter screen 11. A chute 31 is opened at the end of the second fixing rod 28 away from the fixing rod. The second brush plate 29 is slidably provided in the chute 31. A compression spring 32 is provided in the chute 31. Both ends of the compression spring 32 are abutted against the side wall of the chute 31 and the top of the second brush plate 29 respectively. Through the setting of the compression spring 32, the second brush plate 29 can continuously slide and abut against the upper surface of the second filter screen 11. A plurality of brush blocks with cleaning brushes driven at the bottom are provided on the second brush plate 29, which is convenient for cleaning the second filter screen 11. The initial position of the second brush plate 29 is as Figure 2 shown.

[0024] As Figure 2 , Figure 4 , Figure 6 and Figure 7As shown in the figure, a stirring member that rotates and drives continuously in the same direction along with the driving rod 14 is provided in the stirring chamber 4. An internally toothed ratchet 33 coaxial with it is rotatably provided at one end of the shaft rod 23 away from the driving rod 14. Mounting brackets 34 are fixedly provided on both the driving rod 14 and the shaft rod 23. A driving head 35 is provided on each mounting bracket 34, and a ratchet pawl 36 that mates with the ratchet teeth on the internally toothed ratchet 33 is provided on each driving head 35. Since the first bevel gear 22 and the second bevel gear 24 are respectively located on both sides of the third bevel gear 25 and the rotation directions of the first bevel gear 22 and the second bevel gear 24 are opposite, the rotation directions of the driving rod 14 and the shaft rod 23 are opposite. At this time, when the mounting bracket 34 on the driving rod 14 rotates, the mounting bracket 34 on the shaft rod 23 will rotate in the opposite direction. Due to the mating between the ratchet teeth on the internally toothed ratchet 33 and the ratchet pawl 36 on the driving head 35, when one ratchet pawl 36 drives the internally toothed ratchet 33 to rotate, the other ratchet pawl 36 will slide in the opposite direction in the internally toothed ratchet 33. Therefore, no matter whether the driving rod 14 rotates forward or backward, it will drive the internally toothed ratchet 33 to rotate in one direction. As Figure 7 shown, a telescopic groove 37 is formed in each driving head 35, and each ratchet pawl 36 is slidably mounted in the telescopic groove 37. A second spring 38 is provided in each telescopic groove 37, and both ends of each second spring 38 are fixedly connected to the bottom of the corresponding telescopic groove 37 and one side of the ratchet pawl 36 respectively. This setting facilitates the telescoping of the ratchet pawl 36 on the driving head 35. As Figure 2 shown, the stirring member includes a rotating rod 39 and a plurality of stirring rods 40. One end of the rotating rod 39 is fixedly provided at the bottom of the internally toothed ratchet 33 and is coaxial with the internally toothed ratchet 33. The other end of the rotating rod 39 extends vertically downward into the stirring chamber 4, and a plurality of stirring rods 40 are fixedly provided on a section of the rotating rod 39 extending into the stirring chamber 4. The rotation of the internally toothed ratchet 33 can effectively drive the rotating rod 39 and the stirring rods 40 to rotate in the stirring chamber 4, facilitating the mixing of chemical wastewater and neutralizing liquid.

[0025] As Figure 2 shown, a vibrating rod 41 is rotatably provided inside the outer housing 1 and below the second filter screen 11. A cam 42 for vibrating the second filter screen 11 is fixedly provided on the vibrating rod 41. This method can further discharge the mixed solids on the second filter screen 11 from the outer housing 1.

[0026] Working principle: During use, the rotation of the servo 13 causes the driving rod 14 to rotate. When the driving rod 14 rotates, it drives the connecting rod 15 to move, causing the sealing ball 17 at the end of the connecting rod 15 to roll. Chemical wastewater and neutralizing liquid flow into the filtration chamber 5 from the liquid pipe 6 and further flow to the stirring chamber 4. The rotation of the driving rod 14 can drive the first bevel gear 22 to rotate. When the first bevel gear 22 rotates, it drives the third bevel gear 25 and the second bevel gear 24 to rotate. When the second bevel gear 24 rotates, it drives the shaft rod 23 to rotate. The rotation of the driving rod 14 and the shaft rod 23 causes the mounting bracket 34 installed on the driving rod 14 or the shaft rod 23 to drive the connected driving head 35 to rotate. Further, through the cooperation of the ratchet 36 on the driving head 35 with the internal ratchet 33, the internal ratchet 33 and the rotating rod 39 and the stirring rod 40 installed below the internal ratchet 33 are driven to rotate, and the chemical wastewater and neutralizing liquid flowing into the stirring chamber 4 are stirred and mixed. After mixing and standing for a period of time, by opening the valve 9, the mixture moves onto the second filter screen 11. Through the separation of the second filter screen 11, the liquid flows out from the liquid discharge port 12, and the solid flows out from the discharge port 10.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
