DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1 - Fig.13 A filtering device for treating waste acid water comprises a treatment box 1, and a water inlet pipe 47 (such as Fig.11 As shown), a drain pipe 48 is fixedly connected to the lower part of the inner wall of the processing box 1, and an electric butterfly valve is installed in the drain pipe 48.

[0039] The neutralization reaction mechanism includes a first plate 2 fixedly connected to the inner wall of the processing box 1 (combined with Figure 2 and Figure 4 ), a hollow rod 3 is rotatably connected to the middle of the first plate 2 through a seal, and a plurality of hollow plates 4 are fixedly connected to the inner wall of the hollow rod 3. A plurality of liquid outlet holes 5 (such as Figure 2 As shown, the inner wall of the first plate 2 is provided with a circular cavity 6, and the inner wall of the hollow rod 3 located in the circular cavity 6 is provided with a plurality of liquid inlet holes 7 (as shown in FIG. Figure 4 As shown, a liquid pump 8 is fixedly connected to the side wall of the processing box 1, and the output end of the liquid pump 8 is connected to the inner wall of the circular cavity 6 through a liquid outlet pipe 9, and the input end of the liquid pump 8 is fixedly connected to a liquid inlet pipe 10 (as shown Figure 3 as shown).

[0040] The alkaline liquid from the outside passes through the liquid inlet pipe 10, the liquid pump 8, the liquid outlet pipe 9, the circular cavity 6, the multiple liquid inlet holes 7, the hollow rod 3 and the hollow plate 4, and then flows out through the multiple liquid outlet holes 5, and performs a neutralization reaction treatment on the waste acid water located in the treatment box 1, so that the pH value of the waste acid water remains neutral. At the same time, the first plate 2 and the hollow rod 3 are sealed and rotatably connected. Then, during the rotation of the hollow rod 3, the alkaline liquid flowing out from the multiple liquid outlet holes 5 can evenly contact and react with the waste acid water, thereby increasing the neutralization reaction treatment efficiency of the waste acid water.

[0041] The inner wall of the treatment box 1 is fixedly connected with a pH detector 11 (such as Figure 3 As shown), the pH detector 11 is electrically connected to the liquid pump 8 through an external control mechanism. Further, the pH detector 11 can detect the pH value of the waste acid water in the treatment box 1. This is a prior art. According to the detection value of the pH detector 11, the external control mechanism controls the amount of alkaline liquid pumped into the liquid pump 8, and the amount of pumped liquid is inversely proportional to the detection value, so as to avoid adding too little alkaline liquid, resulting in poor waste acid water treatment effect, and to avoid adding too much alkaline liquid, so that the waste acid water is converted into waste alkaline water.

[0042] The filter mechanism includes two first one-way bearings 13 (such as Figure 5 As shown, the inner wall of the treatment box 1 is rotatably connected to a first rod 12, the first rod 12 is located above the first plate 2, the side walls of the first rod 12 are fixedly connected to the inner walls of two first one-way bearings 13, the outer walls of the two first one-way bearings 13 are fixedly connected to a support plate 14, and the side wall of the support plate 14 away from the inner wall of the treatment box 1 is evenly fixedly connected to three filter boxes 15 (as shown in FIG. Figure 5 and Fig.12 As shown, the filter box 15 is provided with a plurality of filter holes 16 (as shown in FIG. Figure 5 as shown).

[0043] Two water pumps 33 are fixedly connected to the side walls on both sides of the treatment box 1. The input end of the water pump 33 is connected to the lower part of the inner wall of the treatment box 1 through a suction pipe 34. The output end of the water pump 33 is fixedly connected to a water outlet pipe 35. The water outlet pipe 35 is away from the water outlet of the water pump 33 and is directly opposite to the filter box 15 located above. The waste acid water can be continuously transported to the filter box 15 located above, so that the filter box 15 located above filters the waste acid water.

[0044] A filter press mechanism is provided in the filter box 15, and the filter press mechanism includes a second plate 17 and a third plate 18. A plurality of sliding rods are fixedly connected between the second plate 17 and the third plate 18, and the side walls of the sliding rods are slidably connected to the inner wall of the filter box 15. The second plate 17 is located outside the filter box 15, and the side walls of the second plate 17 are elastically connected to the side walls of the filter box 15 through a plurality of first springs 19.

[0045] The processing box 1 is provided with an extrusion mechanism, which includes a second one-way bearing 27 (such as Figure 4 As shown, a fourth plate 25 is fixedly connected to the upper inner wall of the processing box 1, and a second rod 26 is rotatably connected to the lower end of the fourth plate 25. The side wall of the second rod 26 is fixedly connected to the inner wall of the second one-way bearing 27, and the outer wall of the second one-way bearing 27 is fixedly connected to two cams 28 (as shown in FIG. Figure 4 As shown, the inner wall of the processing box 1 near the fourth plate 25 is provided with four through slots 22, and the inner walls of the two through slots 22 on the same side are slidably connected to a pressing plate 23 (as shown in FIG. Figure 8 As shown in FIG. 1 ), the pressing plate 23 is directly opposite to the second plate 17 located above (as shown in FIG. Figure 5 As shown in the figure), the side wall of the pressing plate 23 is elastically connected to the inner wall of the through groove 22 through a plurality of second springs 24.

[0046] A motor 29 is fixedly connected to the side wall of the processing box 1, a first bevel gear 30 is fixedly connected to the side wall of the first rod 12, a second bevel gear 31 meshing with the first bevel gear 30 is fixedly connected to the upper end of the hollow rod 3, and a third bevel gear 32 meshing with the first bevel gear 30 is fixedly connected to the lower end of the second rod 26.

[0047] It should be noted that when the motor 29 drives the first rod 12 to rotate clockwise, the first rod 12 drives the third bevel gear 32 to rotate counterclockwise through the first bevel gear 30 (eg, Figure 4 As shown in the figure, the second rod 26 rotates counterclockwise, at this time the inner ring of the first one-way bearing 13 does not drive its outer ring to rotate, and the inner ring of the second one-way bearing 27 drives its outer ring to rotate. When the motor 29 drives the first rod 12 to rotate counterclockwise, the first rod 12 drives the third bevel gear 32 to rotate clockwise through the first bevel gear 30, and the second rod 26 rotates clockwise. At this time, the inner ring of the first one-way bearing 13 drives its outer ring to rotate, and the inner ring of the second one-way bearing 27 does not drive its outer ring to rotate.

[0048] When the second rod 26 rotates counterclockwise, the second one-way bearing 27 drives the two cams 28 to rotate, so that the two cams 28 intermittently squeeze or separate the two pressure plates 23. At this time, the pressure plate 23 moves left and right (such as Figure 5 As shown), at this time, the pressure plate 23 will intermittently squeeze or separate the second plate 17. At this time, the second plate 17 will drive the third plate 18 to move left and right through multiple slide bars under the squeezing of the pressure plate 23 and the elastic force of the multiple first springs 19 (as shown). Figure 5 As shown), the waste acid water entering the upper filter box 15 is continuously squeezed and treated, and the impurities in the waste acid water are filtered and removed.

[0049] It should be noted that when the third plate 18 moves to the leftmost position (such as Figure 5As shown), at this time, there is still a certain distance between the side wall of the third plate 18 and the inner wall of the filter box 15. At this time, the outlet pipe 35 is far away from the pipe mouth of the water pump 33 and is just above the distance, which will not affect the continuous entry of the waste acid water, nor will the waste acid water be squeezed out from the top of the filter box 15. When there are many impurities in the filter box 15, the filter box 15 corresponding to the outlet pipe 35 can be replaced.

[0050] Two impurity removal openings 20 are formed on the inner wall of the treatment box 1 near the support plate 14. The bottoms of the two impurity removal openings 20 are fixedly connected with impurity removal plates 21. The upper ends of the two impurity removal plates 21 are attached to the lower ends of the two filter boxes 15 located below (such as Figure 6 as shown).

[0051] When there are a lot of impurities accumulated in the filter box 15 located at the top, the motor 29 drives the first rod 12 to rotate counterclockwise, the inner ring of the first one-way bearing 13 drives its outer ring to rotate, and then drives the support plate 14 to rotate counterclockwise, and drives the three filter boxes 15 to rotate 120° counterclockwise, so that the filter box 15 with more impurities accumulated is rotated to the vicinity of the impurity removal plate 21, and the filter box 15 without impurities is rotated to the top to continue filtering. At this time, there is no need to stop the machine to clean the impurities, avoiding the current filtering through a single filter. When there are a lot of impurities accumulated above the filter, the staff is required to stop the machine to disassemble the filter and then clean the impurities, which not only reduces the filtration efficiency of the waste acid water, but also the frequent disassembly and installation as well as manual cleaning increase the workload of the staff.

[0052] It should be noted that when the support plate 14 drives the three filter boxes 15 to rotate counterclockwise, the two cams 28 are at the initial position (eg Figure 3 As shown in FIG. 1 ), the two cams 28 are separated from the two pressing plates 23, and the two pressing plates 23 are located at the initial position (as shown in FIG. 1 ) under the elastic force of the plurality of second springs 24. Figure 7 and Figure 8 As shown in FIG. 1 ), the pressing plate 23 is away from the second plate 17 and will not hinder the normal rotation of the three second plates 17 on the three filter boxes 15 .

[0053] The inner wall of the treatment box 1 near the support plate 14 is slidably connected to two first rectangular rods 36, and the side walls of the two first rectangular rods 36 close to each other are fixedly connected to arc plates 37, and the two arc plates 37 are located between the three filter boxes 15 (such as Fig.13 As shown), at this time, the two arc-shaped plates 37 can be used to guide and process the wastewater filtered by the filter box 15 located above, so as to prevent the wastewater from flowing out through the two filter boxes 15 located below.

[0054] like Figure 8As shown, both ends of the pressure plate 23 are fixedly connected with a first wedge plate 38, and the side wall of the first rectangular rod 36 away from the arc plate 37 is fixedly connected with a second wedge plate 39, the second wedge plate 39 is L-shaped, and the side wall of the second wedge plate 39 is elastically connected to the side wall of the processing box 1 through a plurality of third springs 40, and the first wedge plate 38 and the second wedge plate 39 are matched with each other at the side walls close to each other.

[0055] During the left-right movement of the pressure plate 23, the first wedge plate 38 is intermittently squeezed and separated from the second wedge plate 39. At this time, the second wedge plate 39 moves forward and backward under the squeeze of the first wedge plate 38 and the action of the plurality of third springs 40 (eg, Figure 8 As shown), at this time, the second wedge plate 39 will drive the arc plate 37 to move forward and backward through the first rectangular rod 36 (as shown in FIG. Figure 5 and Figure 8 As shown), the arc plate 37 impacts the filter box 15 close to accelerate the outflow of impurities in the filter box 15.

[0056] An annular groove 41 is formed on the inner wall of the treatment box 1 near the support plate 14, and three fixing plates 42 (such as Figure 5 and Fig.10 As shown in the figure, the side wall of the fixing plate 42 close to the first rod 12 is elastically connected to a block 44 through a plurality of magnetic springs 45, the side wall of the fixing plate 42 is slidably connected to a second rectangular rod 43, one end of the second rectangular rod 43 close to the first rod 12 is fixedly connected to the side wall of the block 44, and the annular groove 41 is provided with three slots 46 that match the three blocks 44 one by one.

[0057] It should be noted that after the magnetic spring 45 is energized, due to electromagnetic induction, the magnetic spring 45 interacts with the current in the external magnetic field to generate pulling forces of different magnitudes to control the tensile deformation and motion state of the magnetic spring 45, such as Fig.10 As shown, when the three filter boxes 15 need to rotate counterclockwise, the multiple magnetic springs 45 are first energized and contracted, driving the three clamping blocks 44 to separate from the three clamping slots 46, and then the three filter boxes 15 rotate counterclockwise. After the three filter boxes 15 rotate 120°, the multiple magnetic springs 45 are de-energized and extended, so that the three clamping blocks 44 are all stuck in the three clamping slots 46, limiting the positions of the three filter boxes 15, thereby ensuring the stability of the upper filter box 15 when filtering impurities in the waste acid water.

[0058] When treating the waste acid water, firstly, the waste acid water is added into the treatment box 1 through the water inlet pipe 47, and then the liquid pump 8 is started, and then the alkaline liquid from the outside passes through the liquid inlet pipe 10, the liquid pump 8, the liquid outlet pipe 9, the circular cavity 6, the multiple liquid inlet holes 7, the hollow rod 3 and the hollow plate 4, and then flows out through the multiple liquid outlet holes 5, and the waste acid water in the treatment box 1 is subjected to a neutralization reaction treatment, so that the pH value of the waste acid water remains neutral;

[0059] The driving motor 29 rotates clockwise, and the first rod 12 drives the hollow rod 3 to rotate through the first bevel gear 30 and the second bevel gear 31. During the rotation of the hollow rod 3, the alkaline liquid flowing out of the multiple liquid outlets 5 can contact and react with the waste acid water, thereby increasing the neutralization reaction treatment efficiency of the waste acid water.

[0060] At the same time, the pH detector 11 can detect the pH value of the waste acid water in the treatment box 1. According to the detection value of the pH detector 11, the external control mechanism will control the amount of alkaline liquid pumped into the liquid pump 8, and the pumping amount is inversely proportional to the detection value, so as to avoid adding less alkaline liquid, resulting in poor treatment effect of the waste acid water, and avoid adding more alkaline liquid, so that the waste acid water is converted into waste alkaline water;

[0061] During the treatment of the waste acid water, two water pumps 33 are started, and the water pumps 33 continuously transport the waste acid water in the treatment box 1 to the filter box 15 located above through the water suction pipe 34 and the water outlet pipe 35, so that the filter box 15 located above filters the waste acid water through the multiple filter holes 16, and the filtered waste water is discharged through the two arc plates 37 for treatment;

[0062] When the motor 29 rotates clockwise, the first rod 12 drives the second rod 26 to rotate counterclockwise through the first bevel gear 30 and the third bevel gear 32, and the inner ring of the second one-way bearing 27 drives the outer ring thereof to rotate, so that the two cams 28 intermittently squeeze or separate the two pressure plates 23. At this time, the pressure plate 23 moves left and right (such as Figure 5 As shown), at this time, the pressure plate 23 will intermittently squeeze or separate the second plate 17. At this time, the second plate 17 will drive the third plate 18 to move left and right through multiple slide bars under the squeezing of the pressure plate 23 and the elastic force of the multiple first springs 19 (as shown). Figure 5 As shown), the waste acid water entering the upper filter box 15 is continuously squeezed and filtered to remove impurities in the waste acid water;

[0063] When there are many impurities accumulated in the filter box 15 located at the top, first, the multiple magnetic springs 45 are energized and contracted, driving the three clamping blocks 44 to separate from the three clamping slots 46, and then the motor 29 is started to drive the first rod 12 to rotate counterclockwise, and the inner ring of the first one-way bearing 13 drives its outer ring to rotate, thereby driving the support plate 14 to rotate counterclockwise, and driving the three filter boxes 15 to rotate 120° counterclockwise, so that the filter box 15 with more accumulated impurities rotates to the position close to the impurity removal plate 21, and the filter box 15 without impurities rotates to the top to continue filtering. After the three filter boxes 15 rotate 120°, the multiple magnetic springs 45 are de-energized and extended, so that the three clamping blocks 44 are all stuck in the three clamping slots 46, limiting the positions of the three filter boxes 15, and ensuring the stability of the upper filter box 15 when filtering impurities in the waste acid water;

[0064] At this time, the impurities in the filter box 15 below will flow out through the impurity removal plate 21 under the action of gravity, and during the left and right movement of the pressure plate 23, the first wedge plate 38 will be intermittently squeezed and separated from the second wedge plate 39, and the second wedge plate 39 will move forward and backward under the squeezing of the first wedge plate 38 and the action of the plurality of third springs 40 (such as Figure 8 As shown), at this time, the second wedge plate 39 will drive the arc plate 37 to move forward and backward through the first rectangular rod 36 (as shown in FIG. Figure 5 As shown), the arc plate 37 impacts the filter box 15 close to accelerate the outflow of impurities in the filter box 15;

[0065] After the waste acid water is neutralized and the impurities therein are completely filtered out, the electric butterfly valve is opened to discharge the treated waste acid water through the drain pipe 48 .

[0066] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
