The rotating mechanism 6 comprises a sleeve 61 and a positioning rod 62, the positioning rod 62 is a round rod and is integrally formed with the outer side wall of the sleeve 61, the sleeve 61 is sleeved on the stirring rod 32 and is in threaded connection with the stirring rod 32, the turnover plate 33 penetrates in the vertical direction and is provided with a rotating hole 331, and the rotating hole 331 is a long-strip-shaped through hole. And the length direction of the rotation hole 331 coincides with the length direction of the flipping plate 33. The sleeve 61 is inserted into the rotating hole 331, the sliding groove 332 is formed in the inner wall of the rotating hole 331 along the length direction of the rotating hole 331, the positioning rod 62 is inserted into the sliding groove 332, and when the turnover plate 33 is turned over, the positioning rod 62 can slide along the sliding groove 332 and rotate relatively, so that the sleeve 61 is lifted and lowered without rotating.
The pitch of the sleeve 61 and the stirring rod 32 is such that when the sleeve 61 is lifted, the stirring rod 32 is driven to rotate. In addition, in the initial state, that is, when no chemical wastewater exists in the accommodating tank 330, the counterweight 34 may be disposed such that the end of the turnover plate 33 away from the counterweight 34 is inclined upward; when a proper amount (not fully loaded) of chemical wastewater is loaded in the containing groove 330, the end of the turning plate 33 far away from the counterweight block 34 will overcome the blocking forces such as the gravity of the counterweight block 34, the friction between the inner wall of the chute 332 and the side wall of the positioning rod 62, and the friction between the sleeve 61 and the stirring rod 32, and the like, and descend; thereby it is achieved that:
chemical wastewater enters the containing groove 330 through the water inlet 10, and in the process that the chemical wastewater gradually fills the containing groove 330, one end of the turnover plate 33 close to the containing groove 330 gradually descends, so that the sleeve 61 is driven to descend, and the stirring rod 32 is driven to rotate.
In the process of gradually overturning the turnover plate 33 downwards, the chemical wastewater in the accommodating groove 330 is gradually dumped after reaching the maximum storage amount until the balancing weight 34 drives the turnover plate 33 to recover the initial state, and in the process, the sleeve 61 moves upwards to drive the stirring rod 32 to reversely rotate.
In conclusion, in the process that the chemical wastewater continuously falls through the water inlet 10, the turnover plate 33 rotates up and down in a reciprocating manner, so that the sleeve 61 is driven to move up and down, and the stirring rod 32, the stirring blade 31 and the cleaning strip 7 are driven to rotate in a reciprocating manner.
Referring to fig. 1 and 2, a cleaning device 9 is arranged on the side wall of the filter box 1 for scraping residual media on the filter screen 2, and the cleaning device 9 includes a rotating ring 91, a conveyor belt 92, a linkage ring 93, a linkage rod 94, a connecting plate 95 and a limiting block 96. The rotating ring 91 is coaxially fixed with the stirring rod 32, the rotating ring 91 is rotatably connected with the inner top wall of the filter box 1, the linkage ring 93 is rotatably connected with the inner top wall of the filter box 1, the linkage rod 94 is vertically arranged, one end of the linkage rod 94 is coaxially fixed with the linkage ring 93, and the other end of the linkage rod 94 is welded and fixed with the limiting block 96. The conveyor belt 92 is wound on the outer side walls of the rotating ring 91 and the link ring 93, and the outer edge diameter of the link ring 93 is larger than that of the rotating ring 91. The middle section of the linkage rod 94 penetrates through the connecting plate 95 and is in threaded connection with the connecting plate 95, the supporting rod 15 is fixedly welded on the side portion of the connecting plate 95, a supporting groove 16 is formed in the inner wall of one side, close to the supporting rod 15, of the filter box 1, the supporting rod 15 is inserted into the supporting groove 16 in a matched mode, and the connecting plate 95 is in sliding connection with the filter box 1. One side adhesive fixation that connecting plate 95 is close to filter screen 2 has brush 951, and one side and the filter screen 2 lateral wall looks butt of connecting plate 95 is kept away from to brush 951.
In the reciprocating rotation process of the stirring rod 32, the rotating ring 91, the conveying belt 92, the linkage ring 93 and the linkage rod 94 are sequentially driven to rotate in a reciprocating manner, so that the connecting plate 95 is driven to move up and down in a reciprocating manner along the length direction of the linkage rod 94, the brush 951 slides up and down along the filter screen 2, attached media on the filter screen 2 are scraped, and the effect of cleaning the filter screen 2 is achieved.
The implementation principle of the chemical wastewater treatment process in the embodiment of the application is as follows: chemical wastewater is poured into the liquid guide hopper 5 and enters the accommodating groove 330 through the water inlet 10, and in the process that the accommodating groove 330 is gradually filled with the chemical wastewater, one end, close to the accommodating groove 330, of the turnover plate 33 gradually descends, so that the sleeve 61 is driven to descend, the stirring rod 32 is driven to rotate, the rotation of the stirring blade 31 is realized, and the medicines in the filter box 1 are fully mixed with the chemical wastewater;
in the process of gradually overturning the turnover plate 33 downwards, the chemical wastewater in the accommodating groove 330 is gradually dumped after reaching the maximum storage amount until the balancing weight 34 drives the turnover plate 33 to recover the initial state, and in the process, the sleeve 61 moves upwards to drive the stirring rod 32 to reversely rotate. In-process that chemical industry waste water lasts the whereabouts through water inlet 10, the reciprocal up-and-down rotation of returning face plate 33, thereby drive sleeve 61 and reciprocate, and then drive puddler 32, stirring leaf 31 and cleaning strip 7 reciprocating rotation, further strengthen the degree of fusion that medicine and chemical industry waste water mix, after returning face plate 33, the opening slope of storage tank 330 is upwards, continue to accept the chemical industry waste water that trickles down from water inlet 10, the continuous reciprocal motion of turning over that does of returning face plate 33, drive puddler 32 and rotate, thereby it is rotatory to drive stirring leaf 31, reach the effect of stirring, accomplish the intensive mixing of medicine and chemical industry waste water, the maximum efficiency of performance medicine, furthest decomposes out the medium in the chemical industry waste water.
In addition, the puddler 32 drives the swivel becket 91 when rotating and rotates, and the swivel becket 91 passes through the transmission of conveyer belt 92, drives linkage ring 93 and rotates, and gangbar 94 rotates promptly to make connecting plate 95 remove on the length direction of gangbar 94, make connecting plate 95 change in the ascending position of vertical side, thereby make the brush 951 of connecting plate 95 lateral wall slide on filter screen 2, scrape adnexed medium on filter screen 2 and take off, reach the effect of clearance filter screen 2.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
