[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a novel shale gas return liquid sewage treatment device, including a reaction barrel 1, a bracket 7 is fixedly connected to one side of the outer wall of the reaction barrel 1, a motor 23 is fixedly connected to one side of the inner wall of the bracket 7, a turntable 14 is fixedly connected to one side of the outer wall of the turntable 14, a transmission rod 2 13 is rotatably connected to one side of the transmission rod 1 12, a slide 8 is provided on both sides of the inner wall of the bracket 7, a slide plate 9 is arranged inside the bracket 7, the slide plate 9 is slidably connected inside the slide plate 8, one side of the bottom of the slide plate 9 is rotatably connected to one side of the transmission rod 1 12, a distribution pipe 10 is fixedly connected to one side of the distribution pipe 10, a bottom cover 11 is rotatably connected to the bottom of the distribution pipe 10, the outer wall of the bottom cover 11 is slidably connected to the outer wall of the bracket 7, and a storage barrel 6 is fixedly connected to the top of the bracket 7;

[0023] Specifically, in chemical experiments, the reaction barrel 1 plays a vital role, and the design of the reaction barrel 1 is even more ingenious. A storage barrel 6 is mounted on a bracket 7 on one side of the outer wall. This design allows the chemical reagent to be conveniently loaded into the storage barrel 6. In order to more effectively control the use of the reagent, a motor 23 is installed inside the reaction barrel 1, which drives the turntable 14 to rotate. The rotation of the turntable 14 further drives the transmission rod 2 13 and the transmission rod 1 12 to do crank motion. This linkage mechanism ensures the accuracy and convenience of the reagent use. Under the coordinated action of rod 12 and transmission rod 2 13, the slide plate 9 slides repeatedly inside the slide groove 8. When the distribution tube 10 on the slide plate 9 slides to the bottom of the storage barrel 6, it can receive the chemical agents inside the storage barrel 6. The design of the bottom cover 11 is also very clever. It is closed by the bracket 7 to ensure the sealing of the storage barrel 6. However, when the distribution tube 10 slides forward, the bottom cover 11 will slide out of the restriction of the bracket 7, so that the chemical agents inside the distribution tube 10 can be discharged. This design not only ensures the accuracy of the agent taking, but also avoids the waste of the agent.

[0024] Reference Figure 1 The outer wall of the reaction barrel 1 is provided with a feeding assembly, which includes a feeding port 5 and a water inlet 3. One end of the water inlet 3 is fixedly connected to one side of the outer wall of the reaction barrel 1, and the bottom of the feeding port 5 is fixedly connected to one side of the top of the reaction barrel 1. The bottom of the outer wall of the reaction barrel 1 is fixedly connected to a water outlet valve 2;

[0025] Specifically, the feed port 5 can receive the chemical agents discharged from the distribution pipe 10 and discharge them into the reaction barrel 1, while the water inlet 3 can allow sewage to be introduced into the reaction barrel 1, and the water outlet valve 2 can control the closure and discharge of sewage in the reaction barrel 1.

[0026] Reference Figure 1 and Figure 3The top wall of the reaction barrel 1 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to a rotating rod 16, both sides of the top of the rotating rod 16 are rotatably connected to rotating gears 17, the top wall of the reaction barrel 1 is fixedly connected to a fixed gear 15, the fixed gear 15 is meshed with the rotating gear 17, a stirring column 18 is fixedly connected to the rotating gear 17 on one side, a rotating plate 21 is fixedly connected to the bottom of the rotating gear 17 on the other side, a fixed gear 2 19 is fixedly connected to one side of the bottom of the rotating rod 16, a rotating gear 2 20 of a ring array is rotatably connected to the top of the rotating plate 21, the rotating gear 2 20 is meshed with the fixed gear 2 19, and a stirring column 22 is fixedly connected to the rotating gear 20;

[0027] Specifically, the rotation of the motor 24 is transmitted through the rotating rod 16, and a rotating gear 17 is installed on the rotating rod 16. When the rotating gear 17 rolls on the fixed gear 15, the rotating gear 17 on one side will drive the stirring column 18 to rotate, and the rotating gear 17 on the other side will drive the rotating plate 21 to rotate. Furthermore, another rotating gear 20 is installed on the rotating plate 21, and the rotating gear 20 will roll around the fixed gear 2 19. This rolling motion enables the rotating gear 20 to drive the stirring column 22 to rotate. In this way, the rotation of the motor 24 is effectively transmitted to the stirring column 18 and the stirring column 22, thereby realizing efficient stirring of the material. This transmission method has a simple structure and reliable operation, and is widely used in various mechanical equipment.

[0028] Working principle: On the bracket 7 on one side of the outer wall of the reaction barrel 1, the chemical agent can be loaded into the storage barrel 6, and then the turntable 14 is rotated by the drive of the motor 23, thereby driving the transmission rod 2 13 and the transmission rod 1 12 to make a crank motion, and then the slide plate 9 is pushed by the transmission rod 12 and the transmission rod 2 13 to slide repeatedly inside the slide groove 8, and when the distribution tube 10 on the slide plate 9 slides to the bottom of the storage barrel 6, the medicine inside the storage barrel 6 can be taken through the distribution tube 10, and the bottom cover 11 is closed due to the support 7, and when the distribution tube 10 slides forward, the bottom cover 11 can slide out of the bracket 7. The frame 7 is limited to discharge the chemical agent in the distribution tube 10, and the slide plate 9 will prevent the agent in the storage barrel 6 from continuing to be discharged. When reacting in the reaction barrel 1, the motor 4 can be used to drive the rotating rod 16 to rotate, so that the rotating gear 17 on the rotating rod 16 rolls on the fixed gear 15, and the rotating gear 17 on one side will drive the stirring column 18 to rotate, and the rotating gear 17 on the other side will drive the rotating plate 21 to rotate, so that the rotating gear 2 20 on the rotating plate 21 rolls around the fixed gear 2 19, so that the rotating gear 20 drives the stirring column 22 to rotate.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
