TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment equipment, in particular to a sewage treatment equipment for preparing raw materials of intestinal metabolic nutrients. BACKGROUND

[0002] Intestinal metabolic nutrients are a class of nutritional supplements that aim to regulate intestinal metabolic function, improve intestinal microecological balance, and promote intestinal health. By supplementing specific ingredients, this type of nutrient can intervene or assist in the intestinal metabolic process, thereby relieving intestinal function disorders and improving overall health.

[0003] The existing Chinese patent document with publication number CN117361666B discloses a food processing sewage treatment equipment and method, which includes a support mechanism, a driving mechanism, a collection mechanism, a stirring mechanism, and a fishing mechanism. The support mechanism includes a containing kettle, a bearing plate, and a bearing bracket, both of which are fixedly installed on the outer wall of the containing kettle. The collection mechanism includes a control cylinder and a collection bucket, which is slidingly installed on the side wall of the bearing plate through the control cylinder. The collection bucket is used to collect flocculent protein generated during sewage treatment. The control cylinder is a common hydraulic cylinder that controls the horizontal reverse sliding of the collection bucket. The stirring mechanism includes a stirring shaft and stirring blades, which are rotatably installed on the side wall of the bearing bracket through the stirring shaft. The stirring blades are evenly distributed in a ring shape on the radial outer wall of the stirring shaft. Rotating the stirring shaft controls the rotation of the stirring blades to achieve stirring. The fishing mechanism includes a net bag, a transmission shaft, and a resilient plate. The net bag is elastically installed on the radial outer wall of the transmission shaft through the resilient plate. The outer wall of the net bag is fixedly connected to one end of the resilient plate, and the other end of the resilient plate is fixedly connected to the radial outer wall of the transmission shaft. Rotating the transmission shaft controls the rotation of the net bag along the axis of the transmission shaft.

[0004] However, the above-mentioned scheme only removes impurities in the sewage through the fishing mechanism, but the treatment effect of the sewage is limited, and the reuse effect of the sewage is poor. Therefore, the present application proposes a sewage treatment equipment for preparing raw materials of intestinal metabolic nutrients to solve the above-mentioned problems. SUMMARY

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-16 The present invention provides the following three preferred embodiments:

An upper rotating shaft support 9 and a lower rotating shaft support 10 are provided on the inner side wall of the treatment tank 1. A primary sealed bearing 11 is installed on both the upper rotating shaft support 9 and the lower rotating shaft support 10. The rotating shaft 2... A first-stage sealed bearing 11 is rotatably mounted on the upper rotating shaft support 9 and the lower rotating shaft support 10.

A transmission gear is fixedly installed on the output shaft of the drive motor. A driven gear 13 is fixedly installed on the rotating shaft 2. The driven gear 13 meshes with the transmission gear. A liquid distribution mechanism 3 is located at the upper end of the rotating shaft 2. The liquid distribution mechanism 3 is used to add flocculant to the treatment tank 1. A stirring shaft 4 is fixed at the upper end of the rotating shaft 2. A slag discharge mechanism 5 is located at the bottom of the treatment tank 1. The slag discharge mechanism 5 is used to discharge the flocculated waste slag in the treatment tank 1.

[0044] A main channel 14 is provided on the rotating shaft 2. An adapter 15 is fixedly installed on the positioning bracket 12. The rotating shaft 2 is rotatably connected to the adapter 15 through a secondary sealed bearing 16. An upper mounting hole and a lower mounting hole are provided on the side wall of the rotating shaft 2. The rotating shaft 2 is threaded into the upper mounting hole, and the stirring shaft 4 is threaded into the lower mounting hole. A connecting hole 17 is provided on the side wall of the upper mounting hole. A secondary flow channel 18 is provided on the liquid distribution mechanism 3. The secondary flow channel 18 is connected to the main channel 14 through the connecting hole 17. A drain is provided on the side wall of the secondary flow channel 18. The liquid hole 19 is a wastewater treatment device for preparing intestinal metabolic nutrients, which is composed of a treatment tank 1, a rotating shaft 2, a liquid distribution mechanism 3, a stirring shaft 4, and a slag discharge mechanism 5. By opening a main flow channel 14 on the rotating shaft 2 and setting a secondary flow channel 18 and a drain hole 19 on the liquid distribution mechanism 3, the flocculant is evenly distributed into the treatment tank 1 through the main flow channel 14, the secondary flow channel 18, and the drain hole 19, so that the impurities in the treatment tank 1 are fully flocculated by the flocculant, thereby effectively improving the wastewater treatment effect in the treatment tank 1.

[0045] A row of drain holes 19 are arranged at equal intervals, and a movable groove 20 is provided at the port of the drain hole 19. A threaded hole 21 is provided at the port of the movable groove 20. A limit member 20 is threadedly connected in the threaded hole 21. A through hole 23 is provided on the limit member 20.

When the support spring 22 is in the reset state, the sealing seat 21 forms a sealing effect on the port of the drain hole 19. Through the setting of the limit member 20, the sealing seat 21, and the support spring 22, the end of the drain hole 19 can be sealed, thereby effectively preventing sewage from flowing back into the drain hole 19 and thus effectively preventing the flocculant from being contaminated.

[0046] Example 2: Based on Example 1, the slag discharge mechanism 5 includes a slag feeding seat 25, a slag collecting pipe 26, a piston 27, a primary sealing plate 28, and a secondary sealing plate 29. The slag feeding seat 25 is integrally formed with the bottom of the treatment tank 1. The slag feeding seat 25 is provided with a connecting groove 30, a primary slag discharge groove 31, and a secondary slag discharge groove 32. The connecting groove 30 is connected to the inner cavity of the treatment tank 1. The slag collecting pipe 26 is integrally formed with the slag feeding seat 25. The two sides of the slag collecting pipe 26 are respectively connected to the connecting groove 30 through the primary slag discharge groove 31 and the secondary slag discharge groove 32. Both ends of the slag collecting pipe 26 are fixedly welded with screws 33. The primary sealing plate 28 and the secondary sealing plate 29 are respectively fixed to both ends of the slag collecting pipe 26 by positioning screws.

[0047] The outer walls of both ends of the slag collection pipe 26 are respectively provided with a primary annular groove 34 and a secondary annular groove 35. The bottom of the primary annular groove 34 and the secondary annular groove 35 are provided with filter holes 35. Geotextile 37 is fixedly installed in the primary annular groove 34 and the secondary annular groove 35 through a positioning structure 36. The geotextile 37 is wrapped around the bottom of the annular groove in two layers.

[0048] The positioning structure 36 includes a primary positioning component 38 and a secondary positioning component 39. The ear plates on both sides of the primary positioning component 38 and the secondary positioning component 39 are positioned by bolts and nuts 40. The inner sidewalls of the primary positioning component 38 and the secondary positioning component 39 are integrally formed with positioning strips 41. Multiple positioning strips 41 are evenly arranged, and each positioning strip 41 has a flow hole 42. The lower end of the secondary positioning component 39 is formed with a pipe connection port 43. The pipe connection port 43 is offset from the positioning strip 41, and the pipe connection ports 43 on both sides of the positioning structure 36 are connected by a connecting pipe 44.

[0049] A guide groove 49 is provided on the lower side of the slag collection pipe 26, and a force-bearing seat 48 is fixedly installed on the side wall of the piston 27. The force-bearing seat 48 is movably disposed in the guide groove 49 and is driven by a drive structure.

[0050] The primary slag discharge trough 31 and the secondary slag discharge trough 32 are symmetrically arranged. The guide groove 49 is centrally located on the slag collection pipe 26. When the force-bearing seat 48 moves to the edge of the guide groove 49, the end of the piston 27 moves to abut against the sealing plate. During the reciprocating motion of the force-bearing seat 48 in the guide groove 49, the piston 27 always forms a sealing effect on the guide groove 49. The piston 27 cannot simultaneously form a sealing effect on the lower ends of the primary slag discharge trough 31 and the secondary slag discharge trough 32. By setting the slag discharge mechanism 5 to consist of the slag feeding seat 25, the slag collection pipe 26, the piston 27, the primary sealing plate 28, and the secondary sealing plate 29, the slag discharge mechanism can achieve this. The equipment is assembled and has a connecting groove 30, a primary slag discharge groove 31, and a secondary slag discharge groove 32 on the slag feeding seat 25. This allows the flocculated impurities in the treatment tank 1 to be sent to both ends of the slag collection pipe 26. Then, through the squeezing action of the piston 27, the flocculated and precipitated impurities are squeezed out, so that the water in the impurities is squeezed out. The compressed impurities are then discharged, thereby realizing the continuous operation of the equipment. It can effectively remove impurities from the treatment tank 1 and allow the water squeezed out from the impurities to re-enter the other end of the slag collection pipe 26 along the connecting pipe 44, thereby effectively improving the water reuse rate.

[0051] Example 3: Based on Example 2, a set of guide rod seats 45 are fixedly installed on the lower side of the slag collection pipe 26, and a guide rod 46 is fixedly installed between the two guide rod seats 45. A transmission screw 47 is rotatably installed between the two guide rod seats 45. The transmission screw 47 is driven by a servo motor fixed on the side wall of the slag collection pipe 26. The force-bearing seat 48 is provided with a guide rod hole 50 and a screw hole 51. The guide rod hole 50 and the screw hole 51 are respectively set to correspond to the guide rod 46 and the transmission screw 47. The force-bearing seat 48 is driven by the transmission screw 47.

[0052] The lower end of the treatment tank 1 is hemispherical. During actual installation, the lower end of the rotating shaft 2 extends into the connecting groove 30. The hemispherical shape of the lower end of the treatment tank 1 facilitates the aggregation of flocculated impurities. The lower end of the rotating shaft 2 extends into the connecting groove 30, and the centrifugal force when the rotating shaft 2 rotates can attract the flocculated impurities into the connecting groove 30, thereby allowing the flocculated impurities to be discharged more fully.

[0053] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
