[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0031] Such as Figure 1 、 2, as shown in FIGS. 3, an automatic spraying wastewater treatment device is provided with a first water tank 1 and a second water tank 2. The first water tank 1 and the second water tank 2 are connected by a pipeline. An antifoaming mechanism 3, a bubble isolation mechanism 4, and a chemical dosing mechanism 5 are arranged on the first water tank 1. A slag-liquid separation mechanism 6 is arranged in the second water tank 2. The bubble isolation mechanism 4 aggregates the bubbles in the first water tank to the antifoaming mechanism 3, and the antifoaming mechanism 3 performs defoaming treatment. The chemical dosing mechanism 5 adds chemicals to the first water tank 1. The wastewater after chemical addition is transferred to the second water tank 2 through the pipeline by pumping for slag-liquid separation. The automatic spraying wastewater treatment device is also provided with a controller, and the controller controls each mechanism to execute according to a predetermined action.

[0032] As Figure 1 , 2 shown, the antifoaming mechanism 3 includes a support frame 31 arranged on the body of the first water tank 1, and an antifoamer 32 is fixedly arranged on the support frame 31. The antifoamer 32 performs defoaming treatment on the bubbles in the first water tank 1.

[0033] As Figure 1 , 3 shown, the bubble isolation mechanism 4 includes a partition plate 41 arranged on the first water tank 1, and isolation sliders 42 are respectively arranged at both ends of the partition plate 41; the bubble isolation mechanism 4 further includes isolation lead screws 43 arranged on both sides of the first water tank 1. The isolation lead screws 43 are connected to a lead screw motor 44. The lead screw motor 44 can drive the isolation lead screws 43 to rotate so as to drive the isolation sliders 42 to reciprocate. An isolation lifting cylinder 45 is also arranged on the isolation slider 42. The piston rod of the isolation lifting cylinder 45 is connected to the partition plate 41, and the isolation lifting cylinder 45 can drive the partition plate 41 to rise or fall.

[0034] In the initial state, the piston rod of the isolation lifting cylinder 45 rises, and the lead screw motor 44 drives the isolation lead screws 43 to rotate, moving the partition plate 41 to the side away from the antifoaming mechanism 3. When the partition plate 41 approaches the side of the first water tank 1 where the lead screw motor 44 is located, the piston rod of the isolation lifting cylinder 45 descends, and the partition plate 41 is inserted into the water. The rotation of the isolation lead screws 43 drives the partition plate 41 to move towards the side of the antifoaming mechanism 3, so as to concentrate all the foam in the first water tank 1 under the antifoamer 32 for convenient defoaming.

[0035] As Figure 1 , 4As shown in FIGS. 5, the chemical dosing mechanism 5 is provided with a chemical dosing hopper 51. The chemical dosing hopper 51 has a conical structure. A delivery pipe 52 is provided at the bottom of the chemical dosing hopper 51. The delivery pipe 52 is horizontally arranged. The tail of the delivery pipe 52 is located above the first water tank 1. The delivery pipe 52 is communicated with the chemical dosing hopper 51. A delivery screw 53 is arranged in the delivery pipe 52. The delivery screw 53 is connected to a servo motor 54. The servo motor 54 can drive the delivery screw 53 to rotate so as to realize putting the chemical agent into the first water tank 1 through the delivery pipe 52. In this embodiment, a plurality of chemical dosing hoppers 51 are arranged side by side, and different chemical agents can be added into the first water tank 1 at the same time. A delivery pipe 52, a delivery screw 53 and a servo motor 54 are respectively and correspondingly arranged at the bottom of each chemical dosing hopper 51. Each servo motor 53 is connected to a controller. By controlling the rotation speed of the servo motor 54 through the controller, the dosage of the chemical agent can be accurately controlled, and the corresponding servo motor 53 can be selectively started or stopped according to different added chemical agents.

[0036] As Figure 1 、 6 、7, the slag-liquid separation mechanism 6 is arranged on the second water tank 2. The slag-liquid separation mechanism 6 includes a stirring part 61 arranged inside the second water tank 2; a suspended slag discharge part 62 arranged on the upper part of the second water tank; a precipitation slag discharge part 63 arranged at the bottom of the second water tank. The stirring part 61 stirs the chemical agent added to the wastewater to make the wastewater and the chemical agent react fully. The suspended slag discharge part 62 extracts and separates the suspended matters on the water surface. The precipitation slag discharge part 63 extracts and separates the precipitates under the water.

[0037] As Figure 8 shown, the stirring part 61 includes a stirring shaft 611 arranged in the second water tank 2. Stirring blades 612 are fixedly arranged on the stirring shaft 611. The stirring blades 612 are in an "L" shape. The adjacent stirring blades 612 are arranged at a predetermined distance and angle. One end of the stirring shaft 611 is connected to a stirring motor 613. The stirring motor 613 drives the stirring shaft 611 to rotate to stir and react the waste liquid in the second water tank 2.

[0038] As Figure 1 、 6, as shown in Figures 7, 8, and 9, the suspension slag discharge part 62 is provided with a rotating shaft 621. The rotating shaft includes a first rotating shaft 6211, a second rotating shaft 6212, and a third rotating shaft 6213. The first rotating shaft 6211 and the second rotating shaft 6212 are in the same horizontal plane, and the third rotating shaft 6213 is higher than the second rotating shaft 6212. Both ends of the first rotating shaft 6211, the second rotating shaft 6212, and the third rotating shaft 6213 are provided with gears 622. A slag cleaning chain 623 is arranged on the gear 622. A scraper 624 is detachably installed between the two slag cleaning chains 623. A slag collection plate 625 is arranged below the second rotating shaft 6212 and the third rotating shaft 6213. One end of the slag collection plate 625 close to the third rotating shaft 6213 is higher than the end close to the second rotating shaft 6212. The inclination angle formed by the slag collection plate 625 is the same as the plane angle formed by the third rotating shaft 6213 and the second rotating shaft 6212. The suspension slag discharge part 62 is further provided with a slag discharge driving motor 626. The slag discharge driving motor 626 is connected to the first rotating shaft 6211 through a driving chain 627 and drives the first rotating shaft 6211 to rotate.

[0039] One side of the slag collection plate 625 close to the second rotating shaft 6212 is always under the water surface. The scraper 624 continuously gathers the suspended substances on the water surface onto the slag collection plate 625, which is convenient for collecting the suspended substances and has a good collection effect.

[0040] The precipitation slag discharge part 63 has the same structure as the suspension slag discharge part 62. The chain drives the scraper to collect the sediment that sinks to the bottom of the first water tank, and the sediment is discharged through the pipeline at the bottom of the second water tank 2.

[0041] An automatic spraying wastewater treatment device provided by the present application gathers the bubbles on the liquid surface in the first water tank 1 to the defoaming mechanism 3 through the bubble isolation mechanism 4. The defoaming mechanism 3 defoams and breaks the bubbles on the liquid surface, which can effectively avoid the formation of a bubble film due to a large number of bubbles on the liquid surface, resulting in the inability to directly add the medicament to the water during dosing and affecting the reaction of the medicament. By setting a plurality of dosing hoppers 51, different medicaments can be added to the first water tank 1 at the same time. A delivery pipe 52, a delivery screw 53, and a servo motor 54 are respectively arranged at the bottom of each dosing hopper 51 to accurately control the dosing amount of different medicaments. By setting the stirring part 61, the wastewater in the second water tank 2 reacts fully with the medicament. The suspension slag discharge part 62 collects and separates the suspended substances on the water surface, and the precipitation slag discharge part 63 collects and separates the sediment under the water. The slag-liquid separation effect is good. This device realizes the whole set of processes of waste liquid defoaming, dosing, and slag-liquid separation, with a high degree of automation and integration. The invention has a simple structure, convenient operation, sufficient reaction, and good separation effect.
