DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-Figure 3 As shown, a chemical wastewater treatment device provided by an embodiment of the present invention includes a frame 5 and further includes:

[0030] The device body 1 is installed on the frame 5, and the device body 1 includes a treatment barrel 11, two liquid inlet pipes 12 are symmetrically arranged on both sides of the treatment barrel 11, a dosing pipe 13 is arranged on the top of the treatment barrel 11, and two filter boxes 14 are symmetrically arranged in the area of ​​the treatment barrel 11 between the two liquid inlet pipes 12, each of the filter boxes 14 is provided with a drain pipe 15, and an arc filter screen 16 is arranged between the filter box 14 and the treatment barrel 11;

[0031] The processing module 2 comprises two mounting frames 22, the two mounting frames 22 are respectively mounted in the two liquid inlet pipes 12, a mounting shaft 21 is mounted in the mounting frame 22, a rotating blade 23 is mounted at one end of the mounting shaft 21 away from the processing barrel 11, a mounting block 24 is mounted at one end of each mounting shaft 21 close to the processing barrel 11, and the two mounting blocks 24 are symmetrical about the axis center of the processing barrel 11, a second swing rod 26 is connected between the two mounting blocks 24, a first swing rod 25 is mounted on the second swing rod 26, a scraper plate 27 is respectively mounted at both ends of the first swing rod 25, the scraper plate 27 is slidably mounted on the inner wall of the processing barrel 11 along the circumference of the processing barrel 11, a guide rail 111 for guiding the scraper plate 27 is provided on the inner wall of the processing barrel 11, and the scraper plate 27 is in contact with the inner wall of the arc filter 16 (the side of the arc filter 16 facing the inside of the processing barrel 11 is defined as the inner wall).

[0032] In an embodiment of the present invention, the first swing arm 25 and the second swing arm 26 are connected to form a cross shape. When in use, wastewater is simultaneously transported to the treatment barrel 11 through the two liquid inlet pipes 12, and treatment agents are added to the treatment barrel 11 through the dosing pipe 13 at the top of the treatment barrel 11. When the wastewater in the two liquid inlet pipes 12 is simultaneously transported to the treatment barrel 11, convection will be formed, and the wastewater and the agent can be fully mixed by the impact of the water flow. In addition, when the water flows through the liquid inlet pipe 12, the impact force of the water flow can drive the rotating blades 23 to rotate, and the rotating blades 23 can drive the installation shaft 21 to rotate. It should be supplemented here that, viewed from the same side direction, the two rotating blades 23 have the same rotation direction, thereby ensuring that the two installation shafts 21 have the same rotation direction. The mounting shaft 21 can drive the mounting block 24 to rotate synchronously. Through the cooperation of the two mounting blocks 24, the second swinging rod 26 can be driven to swing periodically. The second swinging rod 26 can drive the first swinging rod 25 to move synchronously, so that the first swinging rod 25 drives the scraper plate 27 to slide linearly back and forth along the guide rail 111, so as to scrape and clean the inner side of the arc filter 16. At the same time, through the periodic swinging of the first swinging rod 25 and the second swinging rod 26, the wastewater in the treatment barrel 11 can also be stirred, thereby further accelerating the mixing of the wastewater and the reagent and improving the treatment efficiency of the wastewater. The treated wastewater will enter the filter box 14 after being filtered by the arc filter 16, and then be discharged through the drain pipe 15.

[0033] like Figure 1 As shown, as a preferred embodiment of the present invention, the bottom of the processing barrel 11 adopts a detachable structure, that is, the bottom plate of the processing barrel 11 can be removed from the main body of the processing barrel 11, so as to facilitate the cleaning of fixed sediments accumulated inside the processing barrel 11.

[0034] like Figure 3-Figure 7 As shown, as a preferred embodiment of the present invention, among the two mounting brackets 22, one mounting bracket 22 is fixedly installed in the corresponding liquid inlet pipe 12, and the other mounting bracket 22 is installed in the corresponding liquid inlet pipe 12 through an adjustment unit 4, and the adjustment unit 4 is used to adjust the connection state between the mounting bracket 22 and the mounting shaft 21;

[0035] When the adjustment unit 4 is in a non-working state, the adjustment unit 4 will fix the mounting frame 22 in the liquid inlet pipe 12, and at this time, the mounting shaft 21 in the mounting frame 22 can rotate;

[0036] When the adjusting unit 4 is in working state, the adjusting unit 4 releases the fixation of the mounting frame 22 , so that the mounting frame 22 can rotate in the liquid inlet pipe 12 , and at the same time fixes the mounting shaft 21 in the mounting frame 22 .

[0037] In the embodiment of the present invention, when the water flow is large, the regulating unit 4 is in a non-working state. At this time, the impact of the water flow on the rotating blades 23 can drive the mounting shaft 21 to rotate, and the mounting frame 22 is fixed in the liquid inlet pipe 12 and will not move. When the water flow is small or there is no water flow input, the regulating unit 4 is started, and the regulating unit 4 will release the limit on the mounting frame 22 and simultaneously fix the mounting shaft 21 in the mounting frame 22. At this time, it is only necessary to drive the mounting frame 22 to rotate through an external drive, so that the mounting shaft 21 is driven to rotate through the mounting frame 22, so that the processing module 2 can also be driven to work as a whole.

[0038] like Figure 5 and Figure 7 As shown, as a preferred embodiment of the present invention, the mounting frame 22 includes a mounting plate 222 for mounting the mounting shaft 21, and the mounting plate 222 is provided with a plurality of connecting columns 221 arranged in a circular pattern along its circumference;

[0039] For the mounting frame 22 fixedly mounted in the liquid inlet pipe 12, the ends of the connecting columns 221 thereon away from the mounting plate 222 are fixedly mounted on the inner wall of the liquid inlet pipe 12;

[0040] For the mounting frame 22 mounted in the liquid inlet pipe 12 through the regulating unit 4 , one end of each connecting column 221 thereon away from the mounting plate 222 abuts against the inner wall of the liquid inlet pipe 12 .

[0041] like Figure 5-7As shown, as a preferred embodiment of the present invention, the adjusting unit 4 includes an adjusting rod 41 that is radially slidably installed in the connecting column 221 along the mounting disk 222, and each of the connecting columns 221 is installed with an adjusting rod 41, a mounting hole 2211 for installing the adjusting rod 41 is opened in the connecting column 221, and the adjusting rod 41 is connected to the inside of the mounting hole 2211 through a spring 42, and an electromagnet 43 is also installed inside the mounting hole 2211, a first latching tooth 411 is provided at one end of the adjusting rod 41 close to the mounting shaft 21, and a second engaging groove 211 matching the first latching tooth 411 is provided on the mounting shaft 21, a second latching tooth 412 is provided at one end of the adjusting rod 41 away from the mounting shaft 21, and a first engaging groove 121 matching the second latching tooth 412 is provided on the inner wall of the liquid inlet pipe 12.

[0042] In the embodiment of the present invention, when in use, when the water flow is large, the electromagnet 43 is closed, and the elastic force of the spring 42 causes the second latching tooth 412 at the end of the adjusting rod 41 to extend from the connecting column 221 and be latched into the first latching groove 121, thereby fixing the mounting frame 22 in the liquid inlet pipe 12. At this time, the first latching tooth 411 does not contact the second latching groove 211. When the water flow is small or there is no water flow input, the electromagnet 43 is started, and the magnetic attraction provided by the electromagnet 43 causes the adjusting rod 41 to retract into the connecting column 221, and causes the first latching tooth 411 to be inserted into the second latching groove 211, and the second latching tooth 412 to be disengaged from the first latching groove 121. At this time, the mounting shaft 21 will keep synchronous movement with the mounting frame 22, and the mounting frame 22 can be driven to rotate by the mounting shaft 21 by the external drive, so that the processing module 2 can also be driven to work as a whole.

[0043] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the liquid inlet pipe 12 connected to the mounting bracket 22 through the adjustment unit 4 is also provided with a driving unit 3 for driving the mounting bracket 22 to rotate.

[0044] In the embodiment of the present invention, when the mounting bracket 22 is not fixed on the inner wall of the liquid inlet pipe 12 , the mounting bracket 22 can be driven to rotate by simply starting the driving unit 3 , thereby driving the mounting shaft 21 to rotate through the mounting bracket 22 .

[0045] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the driving unit 3 includes a gear ring 31 installed in the inner wall of the liquid inlet pipe 12, and a driving box 34 installed on the outer wall of the liquid inlet pipe 12, the gear ring 31 is coaxial with the mounting shaft 21, and the end of the connecting column 221 away from the mounting plate 222 is connected to the inner wall of the mounting shaft 21, a driving motor 33 is installed in the driving box 34, the output end of the driving motor 33 is connected to the driving gear 32, and the driving gear 32 is meshed with the gear ring 31.

[0046] In the embodiment of the present invention, when in use, it is only necessary to start the driving motor 33, and the driving motor 33 can drive the driving gear 32 to rotate. Through the engagement of the driving gear 32 with the gear ring 31, the gear ring 31 can be driven to rotate synchronously, thereby driving the mounting frame 22 to rotate through the gear ring 31.

[0047] Working principle: In the initial state, the electromagnet 43 is closed, and the elastic force of the spring 42 causes the second latching tooth 412 at the end of the adjusting plug rod 41 to extend from the connecting column 221 and be latched into the first latching groove 121, thereby fixing the mounting frame 22 in the liquid inlet pipe 12. At this time, the first latching tooth 411 does not contact the second latching groove 211. When in use, wastewater is simultaneously transported to the treatment barrel 11 through the two liquid inlet pipes 12, and treatment agents are added to the treatment barrel 11 through the dosing pipe 13 at the top of the treatment barrel 11. When the wastewater in the two liquid inlet pipes 12 is simultaneously transported to the treatment barrel 11, convection is formed, and the wastewater and the agent can be fully mixed by the counterflow of the water flow. When the water flow of the wastewater input is large, when the water flow flows through the liquid inlet pipe 12, the impact force of the water flow can drive the rotating blade 23 to rotate, and the rotating blade 23 can drive the mounting shaft 21 to rotate. The mounting shaft 21 can drive the mounting block 24 to rotate synchronously. Through the cooperation of the two mounting blocks 24, the second swinging rod 26 can be driven to swing periodically. The second swinging rod 26 can drive the first swinging rod 25 to move synchronously, so that the first swinging rod 25 drives the scraper plate 27 to slide linearly back and forth along the guide rail 111, so as to scrape and clean the inner side of the arc filter 16. At the same time, through the periodic swinging of the first swinging rod 25 and the second swinging rod 26, the wastewater in the treatment barrel 11 can also be stirred, thereby further accelerating the mixing of the wastewater and the reagent and improving the treatment efficiency of the wastewater. The treated wastewater will enter the filter box 14 after being filtered by the arc filter 16, and then be discharged through the drain pipe 15.

[0048] When the flow of wastewater is small, the electromagnet 43 is started, and the magnetic attraction provided by the electromagnet 43 causes the adjustment rod 41 to retract into the connecting column 221, and causes the first latching tooth 411 to be plugged into the second latching groove 211, and the second latching tooth 412 to be disengaged from the first latching groove 121, at which time the installation shaft 21 and the installation frame 22 keep synchronous movement. Then the drive motor 33 is started, and the drive motor 33 can drive the drive gear 32 to rotate, and through the meshing of the drive gear 32 and the gear ring 31, the gear ring 31 can be driven to rotate synchronously, thereby driving the installation frame 22 to rotate through the gear ring 31, and driving the installation shaft 21 to rotate through the installation frame 22, so that the processing module 2 can also be driven to work as a whole. This ensures that the device can work normally regardless of the size of the water flow.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
