[0002] Sewage deep treatment is based on the requirements of the original water quality and the water quality after treatment. Commonly used methods include: flocculation sedimentation, sand filtration, activated carbon, ozone oxidation, membrane separation, ion exchange, electrolysis, wet oxidation, catalytic oxidation, evaporation concentration and other physical and chemical methods and biological denitrification and dephosphorization methods;

[0003] The existing application number is CN202311064231.4, which is a sewage treatment system for accelerating the diffusion and mixing of medicines. The patent document discloses a method for using a medicine in which the medicine is preliminarily dissolved in a dissolving tank before being put into the sewage pool, and then injected into the sewage pool after being stirred in all directions, so as to improve the diffusion efficiency of the medicine. Specifically, the medicine to be mixed can be evenly discharged into the stirring barrel in a fan shape through the medicine outlet, so that the medicine is dispersed and discharged into the stirring barrel, avoiding the concentration of the added medicines together, and dispersing the added medicines can greatly increase the dispersion rate of the medicines, save mixing time, thereby improving the water treatment efficiency, and realize the structure of dispersing the medicines. The power source used is a driving motor that drives the stirring shaft to rotate, and there is no other An external power source is provided to fully utilize resources and improve resource utilization. In addition, the present invention can also adjust the stirring angle of the stirring side shaft, so that the stirring side shaft can stir and mix the medicine in an all-round manner, so that the medicine can be quickly and evenly mixed and dissolved, thereby improving the efficiency of medicine mixing. When the stirring side shaft revolves around the center of the stirring shaft, it will also rotate by itself, so that the medicine in the stirring barrel can be stirred in an all-round manner. In addition, the electric telescopic rod can change the angle of the stirring side shaft, so that the stirring side shaft can mix the medicine in the stirring barrel in an all-round manner, change the dispersion direction of the medicine, so that the medicine can be evenly dispersed, and improve the medicine mixing rate. In addition, the content of pollutants in sewage is monitored in real time, the error amount is calculated, and the precise medicine spraying rate is calculated;

[0004] However, when using the technical solution in the above-mentioned patent document, the agent is pre-dissolved in the mixing barrel. Although it can increase the dissolution efficiency of the agent in the sewage pool, it also requires a large amount of liquid mixture in the mixing barrel to be applied to the sewage pool before the sewage treatment agent can take effect. In addition, when the content of pollutants in the sewage is monitored in real time, it will be affected by the uneven degree of water pollution, resulting in errors in the monitoring of the pollutant content, increasing the cost of using the facilities and the cost of using drugs. Therefore, the present application provides a sewage deep treatment agent spraying device. Summary of the invention

[0049] Embodiment 1:

[0050] like Figure 1 and Figure 2 As shown, this embodiment provides a sewage deep treatment agent spraying device, including a shuttle-shaped body 1, and a plurality of spray components 2 movably installed on the outer circumference of the shuttle-shaped body 1, and an attachment component 3 located at the end of the spray component 2 and connected to the inner wall of the sewage pool, and a sewage suction component 4 arranged at the bottom of the shuttle-shaped body 1 for draining out solid sediment at the bottom of the sewage pool, and a swing driving component 6 is installed in the shuttle-shaped body 1 for driving the spray component 2 to swing relative to the shuttle-shaped body 1.

[0052] like Figure 8 As shown, one or more drug inlet pipes 23 may be provided, and the drug inlet pipe 23 is connected to a plurality of conducting pipes 25 through a hose and a multi-way connector.

[0053] like Figure 4 As shown, the attachment assembly 3 includes an attachment arm 31 and an articulated seat II 33 fixedly installed on the side of the attachment arm 31; the attachment arm 31 is connected to the inner wall of the sewage pool; in this embodiment, the attachment arm 31 is detachably fixedly connected to the inner wall of the sewage pool by bolts, so that the attachment arm 31 is firmly installed on the inner wall of the sewage pool.

[0054] like Figure 3 , Figure 4 and Figure 7 As shown, a hinge seat Ⅰ14 is fixedly installed on the side of the upright tube 11, an insert tube 22 is slidably installed in the hollow drug guiding tube 21, a tension spring 211 is installed between the hollow drug guiding tube 21 and the insert tube 22 for pulling the insert tube 22 to extend outward from the hollow drug guiding tube 21, and the ends of the hollow drug guiding tube 21 and the insert tube 22 that are away from each other are respectively integrally formed with spherical ends 24, and the spherical ends 24 on the hollow drug guiding tube 21 and the insert tube 22 are respectively engaged and rotatably connected with the hinge seat Ⅰ14 and the hinge seat Ⅱ33.

[0055] like Figure 7 As shown, the specific structure of the tension spring 211 installed between the hollow drug guide tube 21 and the insert tube 22 is shown as follows:

[0056] The end of the hollow drug guiding tube 21 is detachably fixedly installed with an annular end cap, the end of the insert tube 22 located inside the hollow drug guiding tube 21 is integrally formed with an embedded ring 221, a tension spring 211 is fixedly installed between the annular end cap and the embedded ring 221, and both ends of the tension spring 211 are respectively welded with collars, and the two collars are respectively detachably fixedly connected to the annular end cap and the embedded ring 221.

[0057] like Fig.12 As shown, a limit ring 331 is detachably fixedly installed on the articulated seat II 33 , and the split design facilitates the quick disassembly and assembly of the spherical end 24 at the end of the insert 22 in the articulated seat II 33 .

[0058] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the sewage suction component 4 includes a bellows 41 and a sewage pipe 43 which are respectively connected and arranged on the lower and upper sides of the bottom of the upright cylinder 11. A slurry valve 45 is arranged on the sewage pipe 43. The bellows 41 has a built-in steel wire spring or directly uses a corrugated steel wire hose that can be purchased on the market. Flanges are fixedly installed at the upper and lower ends of the bellows 41, and a plurality of multi-stage limit sleeves 42 are arranged between the two flanges. The plurality of limit sleeves on the multi-stage limit sleeve 42 are nested and slidably connected with each other.

[0059] One end of the sewage pipe 43 is connected to the corrugated pipe 41, and the sewage pipe 43 is coiled in the vertical cylinder 11. The other end of the sewage pipe 43 passes through the upper end of the side of the vertical cylinder 11 and extends toward the upper side of the sewage pool.

[0060] The steps of using the sewage deep treatment agent spraying device of the present application to spray sewage treatment agents into the sewage pool are as follows:

[0061] Step 1: Control multiple hollow drug guide tubes 21 to be retracted on the side of the upright tube 11, sink the entire device into the sewage pool, and control the attachment component 3 to connect with the inner wall of the sewage pool.

[0062] Step 2: Inject sewage treatment chemicals into the drug inlet pipe 23, and then the sewage treatment chemicals enter the hollow drug guide cylinder 21 along the hose, and finally spray out from the multiple spray ports on the side of the hollow drug guide cylinder 21 into the sewage pool.

[0063] Step three: Use the swing drive assembly 6 to control the synchronous swing of multiple hollow medicine guide cylinders 21, drive the upright cylinder 11 to periodically sink and float in the sewage pool, dynamically adjust the vertical position of the spray port in the sewage pool, and stir the sewage mixed with sewage treatment agents, so as to quickly disperse the sewage treatment agents at different height levels inside the sewage pool, and implement the sewage treatment agent stirring and diffusion operation; reduce the demand for liquid stirring and circulation inside the sewage pool, and optimize the manufacturing cost and use cost of the facility.

[0064] Step 4: While the upright cylinder 11 is sinking, the bottom of the bellows 41 is in contact with the bottom of the sewage pool. As the upright cylinder 11 continues to sink, a vertical downward extrusion force is applied to the top of the bellows 41, causing the bellows 41 to contract. The slurry valve 45 is opened, allowing the solid sediment from the bottom of the sewage pool to enter the bellows 41 along the bellows 41 and enter the sewage pipe 43; while the upright cylinder 11 is floating, the slurry pump is turned off, so that the sewage containing the solid sediment remains in the sewage pipe 43; as the upright cylinder 11 periodically sinks and floats in the sewage pool, the sewage containing the solid sediment is continuously pressed into the sewage pipe 43, and the solid sediment removal operation at the bottom of the pool is carried out while reducing the sediment removal pressure at the rear end.

[0065] In the above step 2, multiple hollow medicine guide cylinders 21 are distributed around the upright cylinder 11 and extend toward the outside of the upright cylinder 11, so that the spray ports on the multiple hollow medicine guide cylinders 21 are distributed at various positions of the sewage pool, thereby implementing a large-scale spraying operation of sewage treatment agents.

[0066] In the above step three, since the hollow drug guide tube 21 is connected to the attachment component 3 through the insert tube 22, under the action of the tension spring 211, multiple traction insert tubes 22 extend to the outside of their respective corresponding hollow drug guide tubes 21, keeping the distance between the shuttle-shaped main body 1 and the multiple attachment components 3 constant, ensuring that the shuttle-shaped main body 1 will not move in the horizontal direction.

[0067] In the above step four, the amount of solid sediment discharged from the bottom of the pool is used to determine whether the solid sediment in the sewage continues to increase or remains unchanged, so as to control the process of applying the agent. Compared with the solution given in the patent literature in the background technology, which determines whether the sewage has been purified by testing the sewage, the above solution of the present application will not be affected by the uneven degree of water pollution, can reflect the overall degree of sewage purification, reduce the waste of sewage treatment agents, and optimize the cost of medication.

[0068] In this embodiment, the swing drive assembly 6 includes a rope I, and the upper and lower sides of the spherical end 24 at the end of the hollow medicine guide tube 21 are respectively connected to the rope I, and a winding roller and a motor for driving the winding roller to rotate are installed in the upright tube 11, and the other ends of the two ropes I are respectively connected to the two winding rollers; multiple motors are started at the same time to control the rotation of the winding rollers, and the rope I on one side of the spherical end 24 is pulled, so that the corresponding spherical end 24 at the end of the hollow medicine guide tube 21 swings in the hinged seat I14.

[0069] In order to increase the spray range of the sewage treatment agent, the insert 22 is set to a hollow structure inside, and a plurality of anti-backflow spray heads 26 are also arranged on the outside of the insert 22 to increase the number of positions for applying the sewage treatment agent.

[0070] In order to maintain the expansion and contraction performance of the bellows 41, Figure 1 , Figure 2 and Figure 8 As shown, a conical cover 44 is detachably mounted on the outer side of the bellows 41, and the conical cover 44 is made of an elastic and deformable material. The upper end of the conical cover 44 is detachably fixedly connected to the bottom of the upright cylinder 11; the conical cover 44 is used to shield the outer side surface of the bellows 41 to prevent solid precipitation in the sewage pool from adhering to the outer surface of the bellows 41 and affecting the telescopic performance of the bellows 41; in addition, the conical cover 44 is wide at the top and narrow at the bottom, and together with the conical inspection cover 12, it forms a shuttle-shaped structure on both sides of the upright cylinder 11, thereby reducing the resistance of the upright cylinder 11 during the lifting and lowering movement.

[0071] In order to facilitate the continuous use of the equipment, a partition 13 is detachably fixedly installed on the inner side of the bottom of the conical inspection cover 12, and a battery is installed on the upper side of the partition 13. The charging line of the battery passes through the conical inspection cover 12 and extends to the top of the sewage pool. The battery is connected to the power supply port of the linear electric cylinder 65 or the motor through a wire. The wire passes through the partition 13, and a sealed waterproof sleeve is provided at the penetration point. Compared with directly using wires for power supply, the combination of batteries and continuous power supply can ensure long-term continuous and stable operation of the equipment.

[0072] To facilitate the initial installation of the device in the sewage tank, such as Figure 7 As shown, the embedded ring 221 has an iron ring built in it, and the iron ring is connected to the annular electromagnet 29 in the hollow drug guiding tube 21 through magnetic adsorption coupling. When the equipment is initially installed in the sewage pool, the annular electromagnet 29 is started to firmly suck the embedded ring 221 and the annular electromagnet 29 together, so that the insert 22 is completely retracted into the hollow drug guiding tube 21. At this time, the multiple attachment components 3 have a large gap with each surface of the inner wall of the sewage pool, so that the device can be smoothly sunk to the designated position of the sewage pool to avoid collision with the inner wall of the sewage pool.

[0073] Embodiment 2:

[0074] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 5 As shown, in this embodiment, an anti-backflow spray head 26 is installed at the spray port on the side of the hollow medicine guide tube 21. The anti-backflow spray head 26 is a cylindrical structure. An inspection ring 261 and a plurality of one-way guide flaps 262 made of elastic material are fixedly installed inside the anti-backflow spray head 26. The inspection ring 261 is located at the outer end of the anti-backflow spray head 26, and the one-way guide flap 262 opens toward the other end of the anti-backflow spray head 26.

[0075] By utilizing the characteristics of the one-way guiding flap 262 opening toward one side and being able to deform elastically, the sewage treatment agent in liquid form can flow unidirectionally inside the anti-backflow spray head 26 under the action of multiple one-way guiding flaps 262, thereby limiting the sewage from flowing back through the anti-backflow spray head 26 into the hollow medicine guide tube 21 and the insert tube 22, thereby preventing the backflow of sewage from affecting the quality of the sewage treatment agent.

[0076] Embodiment three:

[0077] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Figure 2 , Figure 3 , Fig.10 and Fig.11As shown, in this embodiment, the swing drive assembly 6 includes a lifting ring 62 and a connecting plate 64, and an extension sleeve 28 is fixedly mounted on the spherical end 24 at the end of the hollow drug guide tube 21, and the two extension sleeves 28 at the same vertical position are connected by the connecting plate 64, and the upper and lower ends of the connecting plate 64 are respectively engaged and rotatably connected with the shafts on the sides of the two extension sleeves 28.

[0078] The two hollow drug guiding tubes 21 , the two inserting tubes 22 , the attachment arms 31 and the connecting plate 64 form a parallelogram structure.

[0079] like Fig.10 and Fig.11 As shown, a lifting ring 62 and a linear electric cylinder 65 for driving the lifting ring 62 to move vertically are installed in the hollow drug guiding tube 21. Two or more linear electric cylinders 65 can be provided. The lifting ring 62 is slidably connected to the limit seat 61 on the upper side of the bottom of the hollow drug guiding tube 21. A plurality of transverse shafts 63 are fixedly installed on the side of the lifting ring 62, and the transverse shafts 63 are plugged and fixedly connected to the connecting plate 64.

[0080] Start the linear electric cylinder 65 to control the lifting ring 62 to slide vertically on the limit seat 61, driving the connecting plate 64 to slide horizontally on the corresponding transverse axis 63. During this process, the shaft rod on the side of the extension sleeve 28 rotates relative to the connecting plate 64, and the spherical ends 24 at the ends of the multiple hollow drug guide tubes 21 swing synchronously in their corresponding articulated seats Ⅰ14.

[0081] Compared with the first embodiment, the above-mentioned scheme of the present embodiment reduces the number of required driving components for the rotation control method of the hollow drug guide cylinder 21, optimizes the manufacturing and use costs of the equipment, and increases the convenience of equipment operation and maintenance and the overall economic benefits. In addition, the swinging synchronization of the multiple hollow drug guide cylinders 21 is good, which can ensure the stability of the periodic sinking and floating of the shuttle-shaped main body 1 in the sewage pool, and smoothly implement the large-scale injection operation of sewage treatment agents, the stirring and diffusion operation of sewage treatment agents, and the extraction operation of solid sediment at the bottom of the pool.

[0082] Embodiment 4:

[0083] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 3 and Fig.11 As shown, in this embodiment, a conducting tube 25 is detachably fixedly installed in the hollow drug guiding tube 21, and a one-way valve 27 is provided on the conducting tube 25 to prevent sewage backflow from affecting the quality of the sewage treatment agent. The one-way valve 27 is arranged in the hollow area inside the spherical end 24 at the end of the hollow drug guiding tube 21, and the conducting tube 25 is connected to the drug inlet tube 23 on the side of the upright tube 11 through a hose.

[0084] Since the one-way valve 27 is arranged in the spherical end 24, there is no need to arrange the one-way valve 27 on the hose between the medicine inlet pipe 23 and the conducting pipe 25, and there is no need to reserve too much length at the position where the conducting pipe 25 is located outside the spherical end 24, thereby optimizing the vertical size of the upright cylinder 11; the internal components of the equipment are cleverly combined, the space utilization efficiency is high, and the overall use effect of the equipment is good.

[0085] When the solutions of Example 2 and Example 3 are used in combination, the extension sleeve 28 is only used as an extension component to facilitate the control of the rotation of the hollow medicine guide tube 21, and does not have the function of conducting the sewage treatment agent, thereby avoiding the poor sealing of the narrow connection between the extension sleeve 28 and the spherical end 24, which may cause the sewage treatment agent to leak inside the vertical tube 11; and the connection between the conducting tube 25 and the hollow medicine guide tube 21 is a cylindrical surface, and the connection can be set larger, providing a reliable guarantee for the sealing of the equipment.

[0086] Embodiment five:

[0087] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Fig.12 and Fig.13 As shown, in this embodiment, the attachment arm 31 is provided with an articulated seat II 33, and an elastic pad 34 is fixedly installed on the other side. A plurality of inserting edges 35 are provided on the elastic pad 34. Under the action of the tension spring 211 inside the hollow drug guiding tube 21 and the inserting tube 22, the inserting tube 22 always has a tendency to protrude to the outside of the hollow drug guiding tube 21, so that the inserting edges 35 are embedded with the inner wall of the sewage pool. A lifting ring 32 is fixedly installed on the top of the attachment arm 31, and a rope II is connected to the lifting ring 32. The other end of the rope II extends toward the middle side of the top of the sewage pool.

[0088] Use power equipment such as a crane or a winch to pull multiple ropes II at the same time, apply an oblique upward force to the lifting ring 32, so that the insertion tube 22 shrinks toward the inside of the hollow medicine guide tube 21, and the insertion edge 35 is disengaged from the slot drilled on the inner wall of the sewage pool, so as to remove the entire device from the sewage pool; compared with the connection method between the attachment arm 31 and the inner wall of the sewage pool in Example 1, using the above-mentioned scheme of this embodiment, the entire device can be removed from the sewage pool without completely draining the liquid in the sewage pool, and the operation is highly convenient.

[0089] Embodiment six:

[0090] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Figure 2 , Figure 8 and Fig. 9As shown, in this embodiment, a sludge introduction assembly 5 is provided on the lower side of the bellows 41, and the sludge introduction assembly 5 includes an annular seat 51, which is detachably fixedly mounted on the lower side of the flange at the bottom of the bellows 41, and a plurality of annular flexible sewage guide edges 53 are movably mounted on the bottom of the annular seat 51, and the flexible sewage guide edges 53 are made of rubber or silicone material.

[0091] like Figure 8 and Fig. 9 As shown, the flexible dirt guide edge 53 is annular in structure and is wide at the top and narrow at the bottom, and the bottom is easy to rotate inwards and fold; Figure 2 As shown, the flexible pollution guide edges 53 of multiple annular structures are coaxially arranged and have different height dimensions. From the inside to the outside, the height dimensions of the multiple flexible pollution guide edges 53 gradually increase.

[0092] When the shuttle-shaped body 1 begins to contact the bottom of the sewage pool, the bottom of the flexible sewage guide edge 53 located on the outside is first rotated and gathered inward. As the bottoms of multiple flexible sewage guide edges 53 rotate and gather inward, the sewage containing sediment on the lower side of the annular seat 51 is gradually guided to the middle side of the bottom of the bellows 41, so that a larger range of solid sediment is discharged and processed.

[0093] To prevent the multiple flexible dirt guide edges 53 from forming a suction cup structure at the bottom of the annular seat 51, as shown in FIG. Figure 6 As shown, a plurality of T-shaped columns 54 are fixedly mounted on the top of the flexible sewage guide 53, and the T-shaped columns 54 are slidably connected with the annular seat 51, and a receiving groove 52 is provided at the bottom of the annular seat 51 for accommodating the top of the flexible sewage guide 53 to be embedded and placed.

[0094] As the shuttle-shaped body 1 moves downward, the annular seat 51 applies vertical downward pressure to the flexible sewage guiding edge 53, the bottom of the flexible sewage guiding edge 53 rotates inward and retracts, and the T-shaped column 54 slides relative to the annular seat 51, so that the top of the flexible sewage guiding edge 53 is embedded in the receiving groove 52 at the bottom of the annular seat 51, thereby preventing sewage containing sediment from leaking from the top of the flexible sewage guiding edge 53 and the bottom of the annular seat 51.

[0095] Afterwards, as the shuttle-shaped body 1 moves upward, the T-shaped column 54 slides relative to the annular seat 51, so that the gap between the top of the flexible sewage guiding edge 53 and the bottom of the annular seat 51 is exposed, preventing the annular seat 51 and multiple flexible sewage guiding edges 53 from forming an internally closed suction cup structure, thereby avoiding adverse effects on the reciprocating lifting and lowering movement of the shuttle-shaped body 1.

[0096] Embodiment seven:

[0097] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Fig.11As shown, in this embodiment, a scraper ring 213 is slidably installed on the outer side of the hollow medicine guide barrel 21, and scraping blades are respectively provided at both ends of the scraper ring 213. The scraping blades can fit with the outer side surface of the hollow medicine guide barrel 21 and the end of the anti-backflow spray head 26. The outer side of the hollow medicine guide barrel 21 is integrally formed with two limiting ridges 212 for limiting the sliding range of the scraper ring 213.

[0098] As the shuttle-shaped body 1 periodically sinks and floats in the sewage pool, the hollow medicine guide tube 21 and the insert tube 22 are driven to swing up and down continuously. During this process, the scraper ring 213, under the action of its own weight, continuously slides back and forth on the outside of the hollow medicine guide tube 21, scraping off the solid sediment that may remain at the end of the anti-backflow spray head 26, avoiding the solid sediment from adhering to the end of the anti-backflow spray head 26 for a long time, avoiding adverse effects on the normal delivery of sewage treatment agents.

[0099] In the present application, the one-way valve 27 and the slurry valve 45 both use wireless control valves or Internet of Things electric valves.

[0100] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
