DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides a sewage treatment device for a pig farm, such as Figures 1 to 3As shown, it includes a stirring tube 1 and joint flanges 2 at both ends of the stirring tube 1. The stirring tube 1 is connected to the pipeline by the joint flange 2. A bracket 3 is arranged on the top of the stirring tube 1. A motor 4 is installed on the top of the bracket 3. A rotating rod 5 is inserted through the center of the top surface of the stirring tube 1. The top of the rotating rod 5 is connected to the output end of the motor 4. The bottom end of the rotating rod 5 is inside the stirring tube 1, and the bottom end of the rotating rod 5 is connected to a stirring fan blade. Feed pipes 6 are arranged on both sides of the bracket 3. A material frame 7 is arranged inside the feed pipe 6. The outer side of the circumference of the material frame 7 is connected There are side plates 8, and the surface of the feed pipe 6 is provided with side grooves 9 corresponding to the side plates 8. The bracket 3 is provided with lifting components on both sides, and the lifting components are connected to the side plates 8. The lifting components make the material frame 7 move down inside the feed pipe 6 through the side plates 8. The bottom of the material frame 7 is provided with two semicircular rotating racks 10 for blocking the bottom opening of the feed pipe 6. The two rotating racks 10 are arranged oppositely. Two side plates 11 are fixed on the bottom surface of the material frame 7. The top surface of the rotating rack 10 fits the bottom surface of the side plate 11, and the side plate 11 cooperates with the material frame 7 to block. The stirring tube 1 is connected to the sewage pipe through the joint flange 2. The sewage from the pig farm is introduced into the stirring tube 1 through the sewage pipe. The motor 4 is started. The output end of the motor 4 uses the rotating rod 5 to make the stirring blades rotate inside the stirring tube 1. The rotating stirring blades stir the sewage inside the stirring tube 1 to prevent impurities in the sewage from accumulating inside the stirring tube 1.

[0027] The medicine powder for purifying sewage is put into the material holding frame 7. At this time, the two rotating frames 10 block the bottom of the material holding frame 7 accordingly. While the material holding frame 7 holds the medicine powder, it also prevents the sewage inside the stirring tube 1 from being discharged from the inside of the feeding pipe 6 during the stirring process. The inner end of the lifting component cooperates with the rotating rotating rod 5, and the rotating rotating rod 5 makes the lifting component move up and down. The downwardly moving lifting component drives the material holding frame 7 to move downward inside the material passing pipe 6 through the side plate 8. Since the side grooves 9 cooperate to limit the side plates 8, the material holding frame 7 moves downward smoothly inside the material passing pipe 6. The downwardly moving material holding frame 7 drives the rotating frame 10 to move downward synchronously through the side plates 8. The downwardly moving rotating frame 10 gradually enters the interior of the stirring pipe 1 until the outer circumferential surface of the rotating frame 10 is separated from the inner wall of the material passing pipe 6. The rotating stirring blades vibrate in the process of stirring the sewage. The vibration causes the powder inside the material holding frame 7 to be discharged into the stirring pipe 1 through the gap between the two side plates 11, so that a certain amount of powder can be poured into the stirring pipe 1 to avoid excessive addition of powder.

[0028] After the powder is added, the rotating stirring blades mix the powder into the sewage comprehensively, which is convenient for purifying the sewage. The anti-sticking drug inside the adjacent feed pipe 6 can also be passed into the sewage. The anti-sticking drug moves synchronously with the sewage to prevent impurities in the sewage from adhering to the inner wall of the stirring tube 1 and the inner wall of the sewage pipe.

[0029] exist Figure 2 and Figure 3 In the embodiment, an inner block 12 is fixed to the inner side wall of the material-passing pipe 6, and an elastic rod 13 penetrating the inner block 12 is fixed to the bottom surface of the material-holding frame 7, and the bottom end of the elastic rod 13 is in contact with the top surface of the rotating frame 10. Both sides of the top surface of the rotating frame 10 are provided with spring plates 14, and two spring plates 14 correspond to two side plates 11 one by one, and the top end of the spring plates 14 is connected to the side surface of the side plates 11. The spring plates 14 are in a contracted state, and the elastic force of the spring plates 14 makes the top surface of the rotating frame 10 closely fit with the bottom end of the elastic rod 13, and the elastic rod 13 is in a deformed state. When the material-holding frame 7 moves up and down, the material-holding frame 7 drives the side plates 11 and the elastic rod 13 to move synchronously, and at this time, the elastic rod 13 moves up and down inside the inner block 12, and at this time, the inner block 12 limits the elastic rod 13 to prevent the material-holding frame 7 from rotating inside the material-passing pipe 6.

[0030] exist Figures 2 to 4 In the figure, a ring 15 is fixed to the top surface of the inner end of the rotating frame 10, and the end surface of the ring 15 fits with the inner concave surface of the side plate 11, and the ring 15 is made of soft material. Two cross bars are fixed between the two side plates 11. The two rotating frames 10 correspond to the two cross bars one by one, and the ring 15 is sleeved on the surface of the cross bar. The bottom opening of the feeding pipe 6 is provided with a limiting rod 16, and the bottoms of the two rotating frames 10 are connected by a pull tab 17, and the pull tab 17 corresponds to the limiting rod 16. When the material holding frame 7 drives the side plate 11 to move downward, the side plate 11 uses the cross bar to make the rotating frame 10 move downward synchronously, and the downward moving rotating frame 10 drives the pull tab 17 to approach the limiting rod 16 until the bottom surface of the pull tab 17 is in contact with the surface of the limiting rod 16, and then the material holding frame 7 continues to move downward, and the limiting rod 16 pulls the pull tab 17 to make the rotating frame 10 rotate, and the rotating frame 10 rotates on the surface of the cross bar using the ring 15. The two rotating frames 10 rotate towards each other, and the distance between the top surface of the rotating frame 10 and the bottom end of the elastic rod 13 gradually increases. At this time, the powder inside the material holding frame 7 enters into the mixing tube 1 through the gap between the two side plates 11 under the action of vibration, and the rotating rotating frame 10 cooperates with the side plate 11 to pull the spring piece 14.

[0031] When the material holding frame 7 moves upward, the squeezing force of the limiting rod 16 on the pull tab 17 gradually decreases, and the elastic force of the spring sheet 14 causes the rotating frame 10 to rotate in the opposite direction. The top surface of the rotating frame 10 that rotates in the opposite direction gradually approaches the bottom end of the elastic rod 13 until the top surface of the rotating frame 10 fits with the bottom surface of the elastic rod 13. At this time, the elastic force of the elastic rod 13 itself absorbs the power of the reverse rotation of the rotating frame 10, thereby avoiding collision damage between the rotating frame 10 and the side plate 11.

[0032] exist Figure 2 , Figure 5 and Figure 6In the embodiment, the lifting component includes a movable frame 18, the outer end of the movable frame 18 corresponds to the side plate 8, a screw 19 penetrating the side plate 8 is fixed to the top surface of the outer end of the movable frame 18, a nut is spirally sleeved on the top of the screw 19, the outer end of the movable frame 18 penetrates the bracket 3, and both sides of the bracket 3 are embedded with a vertical rod 20 corresponding to the movable frame 18, the movable frame 18 is sleeved on the surface of the vertical rod 20, a spring 21 is sleeved on the surface of the vertical rod 20, the top of the spring 21 is connected to the bottom surface of the movable frame 18, and the bottom of the spring 21 is connected to the bracket 3. Pull the movable frame 18 downward, the downward movable frame 18 cooperates with the spring 21 that squeezes the surface of the vertical rod 20, at this time, the movable frame 18 pulls the screw 19 to move downward on the surface of the side plate 8, and the nut is spirally sleeved on the top of the screw 19, so as to facilitate the adjustment of the distance between the bottom surface of the side plate 8 and the top surface of the movable frame 18, and to facilitate the adjustment of the height of the side plate 8 moving downward inside the side groove 9. When the movable frame 18 moves downward, the movable frame 18 moves downward synchronously by pulling the side plate 8 with the nut.

[0033] exist Figure 2 and Figure 6 In the embodiment, a slide groove is provided at the center of the movable frame 18, a slide bar 22 is provided inside the slide groove, a push frame 23 is connected to the outer circumferential side surface of the slide bar 22 by a connecting rod, an inner concave surface of the push frame 23 is provided with an internal thread, a threaded portion and two smooth portions are provided on the surface of the rotating rod 5, the threaded portion is located between the two smooth portions, and the inner concave surface of the push frame 23 is spirally matched with the threaded portion of the rotating rod 5. The length of the threaded portion is less than the length of the vertical rod 20. A bottom plate 24 is fixed at the bottom end of the slide bar 22, and side rings are fixed at both ends of the bottom plate 24. Support rods 25 corresponding to the side rings are fixed on both sides of the movable frame 18, and a rotating sleeve 26 is rotatably clamped inside the side ring, and the rotating sleeve 26 is spirally sleeved on the surface of the support rod 25. The rotating sleeve 26 is rotated, and the spiral matching of the rotating sleeve 26 and the support rod 25 facilitates the rotating sleeve 26 to drive the slide bar 22 to move inside the slide groove by using the bottom plate 24, and the relative distance between the push frame 23 and the rotating rod 5 is adjusted in real time by using the spiral matching of the rotating sleeve 26 and the support rod 25.

[0034] When the inner concave surface of the push frame 23 fits with the threaded portion of the rotating rod 5, the rotating rotating rod 5 uses the threaded portion to make the push frame 23 move up and down on the surface of the rotating rod 5. The up and down moving push frame 23 makes the movable frame 18 move up and down on the surface of the vertical rod 20 through the connecting rod. At this time, the movable frame 18 cooperates with the nut and the screw 19 to facilitate the control of the side plate 8 to move up and down inside the side groove 9. The up and down movement of the side plate 8 is used to make the material holding frame 7 move up and down inside the material passing pipe 6.

[0035] According to the flow direction of the sewage, an appropriate feed pipe 6 is selected. After the medicine powder in the material holding frame 7 enters the stirring tube 1, the stirring blades can conveniently stir and mix the medicine powder with the flowing sewage to prevent the medicine powder from floating only on the surface of the sewage.

[0036] Working principle of the present invention:

[0037] Reference Figures 1 to 6 As shown, the rotating sleeve 26 is rotated, and the spiral cooperation between the rotating sleeve 26 and the support rod 25 facilitates the rotating sleeve 26 to use the bottom plate 24 to drive the slide rod 22 to move inside the slide groove, and the spiral cooperation between the rotating sleeve 26 and the support rod 25 is used to adjust the relative distance between the push frame 23 and the rotating rod 5 in real time.

[0038] When the inner concave surface of the push frame 23 fits with the threaded portion of the rotating rod 5, the motor 4 is started, and the output end of the motor 4 causes the rotating rod 5 to rotate. The rotating rotating rod 5 uses the threaded portion to make the push frame 23 move up and down on the surface of the rotating rod 5. The up and down moving push frame 23 makes the movable frame 18 move up and down on the surface of the vertical rod 20 through the connecting rod. At this time, the movable frame 18 cooperates with the nut and the screw 19 to facilitate the control of the side plate 8 to move up and down inside the side groove 9. The up and down movement of the side plate 8 is used to make the material holding frame 7 move up and down inside the material passing pipe 6.

[0039] The stirring tube 1 is connected to the sewage pipe via the joint flange 2. The sewage from the pig farm is introduced into the stirring tube 1 via the sewage pipe. The motor 4 is started. The output end of the motor 4 uses the rotating rod 5 to rotate the stirring blades inside the stirring tube 1. The rotating stirring blades stir the sewage inside the stirring tube 1 to prevent impurities in the sewage from accumulating inside the stirring tube 1.

[0040] The medicine powder for purifying sewage is put into the material holding frame 7. At this time, the two rotating frames 10 block the bottom of the material holding frame 7 accordingly. While the material holding frame 7 holds the medicine powder, it also prevents the sewage inside the stirring tube 1 from being discharged from the inside of the feeding pipe 6 during the stirring process. The inner end of the lifting component cooperates with the rotating rotating rod 5, and the rotating rotating rod 5 makes the lifting component move up and down. The downwardly moving lifting component drives the material holding frame 7 to move downward inside the material passing pipe 6 through the side plate 8. Since the side grooves 9 cooperate to limit the side plates 8, the material holding frame 7 moves downward smoothly inside the material passing pipe 6. The downwardly moving material holding frame 7 drives the rotating frame 10 to move downward synchronously through the side plates 8. The downwardly moving rotating frame 10 gradually enters the interior of the stirring pipe 1 until the outer circumferential surface of the rotating frame 10 is separated from the inner wall of the material passing pipe 6. The rotating stirring blades vibrate in the process of stirring the sewage. The vibration causes the powder inside the material holding frame 7 to be discharged into the stirring pipe 1 through the gap between the two side plates 11, so that a certain amount of powder can be poured into the stirring pipe 1 to avoid excessive addition of powder.

[0041] When the material holding frame 7 drives the side plate 11 to move downward, the side plate 11 uses the cross bar to make the rotating frame 10 move downward synchronously, and the downward moving rotating frame 10 drives the pull tab 17 to approach the limiting rod 16 until the bottom surface of the pull tab 17 is in contact with the surface of the limiting rod 16, and then the material holding frame 7 continues to move downward, and the limiting rod 16 pulls the pull tab 17 to make the rotating frame 10 rotate, and the rotating frame 10 rotates on the surface of the cross bar using the ring 15. The two rotating frames 10 rotate towards each other, and the distance between the top surface of the rotating frame 10 and the bottom end of the elastic rod 13 gradually increases. At this time, the powder inside the material holding frame 7 enters into the mixing tube 1 through the gap between the two side plates 11 under the action of vibration, and the rotating rotating frame 10 cooperates with the side plate 11 to pull the spring piece 14.

[0042] When the material holding frame 7 moves upward, the squeezing force of the limiting rod 16 on the pull tab 17 gradually decreases, and the elastic force of the spring sheet 14 causes the rotating frame 10 to rotate in the opposite direction. The top surface of the rotating frame 10 that rotates in the opposite direction gradually approaches the bottom end of the elastic rod 13 until the top surface of the rotating frame 10 fits with the bottom surface of the elastic rod 13. At this time, the elastic force of the elastic rod 13 itself absorbs the power of the reverse rotation of the rotating frame 10, thereby avoiding collision damage between the rotating frame 10 and the side plate 11.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
