Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to sewage treatment equipment used for municipal water supply and drainage. Background Art

[0002] Municipal wastewater treatment refers to the treatment of wastewater generated by urban life and industrial production through a series of processes and facilities. Its purpose is to remove pollutants such as organic matter, nitrogen, phosphorus, and suspended solids from wastewater, ensuring that it meets national emission standards, thereby protecting the water environment and achieving the recycling of water resources.

[0003] In the sewage treatment process of the municipal water supply and drainage system, adding flocculants to the sewage to achieve the initial separation of pollutants is a key step. At present, common flocculant delivery methods mainly include fixed-point delivery and mobile delivery. Fixed-point delivery equipment is usually fixedly installed at a specific location in the water storage tank, and the flocculant is injected into the sewage through a vertical pipe. This method has significant limitations: first, the flocculant can only cover the area around the pipe and is difficult to spread to the entire water storage tank, resulting in uneven treatment effects and unable to meet large-scale sewage treatment needs; second, due to the fixed delivery point, it is very easy to have excessive delivery in some areas and insufficient delivery in other areas, which not only causes waste of chemicals, but may also affect the normal operation of subsequent sewage treatment processes.

[0004] While mobile delivery equipment can improve coverage issues to a certain extent, existing technologies still have flaws. Most mobile devices use a straight-line or random movement path, continuously delivering flocculants while moving. This results in excessive concentration of flocculants at the starting and end points of the movement trajectory, and a sparse distribution in the middle area, making it impossible to achieve uniform delivery. In addition, some equipment lacks a precise motion control mechanism, making it prone to offset or jamming, affecting the accuracy and continuity of delivery. At the same time, the delivery method of existing equipment is single, mostly vertically downward, and the diffusion effect of the flocculant in the sewage is limited, making it difficult to fully exert the flocculation effect of the agent.

[0005] Based on this, sewage treatment equipment for municipal water supply and drainage is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the above problems and to propose sewage treatment equipment for municipal water supply and drainage.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 5 , the present invention provides a technical solution:

[0029] Sewage treatment equipment for municipal water supply and drainage, including a delivery tube 4, the outer side of the delivery tube 4 is rotatably connected to a sleeve 3, the sleeve 3 structure is sleeved on the outer side of the delivery tube 4, the outer side of the sleeve 3 is connected to a lifting column 8, the lifting column 8 is vertically connected to the outer side of the sleeve 3, the lifting column 8 is connected to a translation frame 5, a slide groove 22 is provided on the translation frame 5, the lifting column 8 is slidably connected to the slide groove 22, and a limit clamp 26 is connected to the lifting column 8. By setting the limit clamp 26, the translation frame 5 is prevented from deflecting left and right. The limit clamp 26 is slidably connected to the translation frame 5, and the outer side of the translation frame 5 is slidably connected to a lifting frame 7, the lifting frame 7 structure is in a vertical state, and the translation frame 5 structure is also in a vertical state. The lifting frame 7 is connected to a transmission member for driving the delivery tube 4 to move;

[0030] The translation frame 5 is connected to a roller frame 18, and a moving roller 19 is rotatably connected to the roller frame 18. The moving roller 19 is provided with two groups. The moving roller 19 structure is in rolling contact with the section steel 1. The moving roller 19 improves the stability of the feeding tube 4 moving on the section steel 1. The upper end of the translation frame 5 is connected to a collar frame 28. The collar frame 28 has two rings connected to each other. The collar frame 28 is connected to the motor 24 and the storage barrel 9. The collar frame 28 makes the motor 24 and the storage barrel 9 fixedly connected. The output end of the motor 24 is connected to the worm 13, and the lower end of the worm 13 is connected to the plug block 27. The feeding tube 4 is connected to a docking column 34 through a cross 31. The docking column 34 is connected to the center position in the feeding tube 4. A groove for docking with the plug block 27 is provided on the docking column 34. The docking column 34 and the plug block 27 fit together. One side of the worm 13 is connected with a feeding mechanism for driving the material in the storage barrel 9 to intermittently feed the material into the feeding tube 4.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, a connecting ring 33 is connected to the outside of the delivery tube 4, and the sleeve 3 is arranged between the connecting rings 33. The connecting ring 33 is provided to limit the position of the sleeve 3 to prevent the sleeve 3 and the delivery tube 4 from being separated from each other.

[0032] Specifically, such as Figure 1 and Figure 3As shown, the transmission part includes a propulsion plate 15, which is connected to a deflection rod 14, which is rotatably connected to the upper end of the lifting frame 7. A steel section 1 is arranged under the propulsion plate 15, and the steel section 1 structure is erected above the sewage storage tank. The flocculant is introduced into the sewage through the delivery tube 4, thereby completing the pretreatment of the sewage. A moving tooth 2 is connected to the steel section 1. By setting the moving tooth 2, the effect of pushing the delivery tube 4 to move after the propulsion plate 15 structure moves is improved, and the contact and slip between the propulsion plate 15 and the steel section 1 is avoided. The lower end of the propulsion plate 15 abuts on the moving tooth 2, and a stop rod 23 is connected between the lifting frames 7. The stop rod 23 structure is used to limit the deflection of the propulsion plate 15. When the equipment moves to one end of the steel section 1, the propulsion plate 15 can be flipped and the motor 24 can be controlled to start, so that the equipment can move in the opposite direction without additional debugging, which greatly facilitates the reciprocating movement of the processing equipment on the steel section 1.

[0033] Specifically, such as Figure 3 As shown, a limiting sleeve 20 is connected to the outer side of the translation frame 5, the lifting frame 7 is slidably connected to the limiting sleeve 20, and the lower end of the lifting frame 7 is rotatably connected to the lifting column 8. The limiting sleeve 20 is provided to limit the lifting frame 7 structure, wherein the limiting sleeve 20 structure is sleeved on the lifting frame 7.

[0034] Specifically, such as Figure 5 As shown, a discharge port 21 is provided at the lower end of the delivery tube 4, and a plurality of discharge ports 21 are provided. The plurality of discharge ports 21 are evenly provided at the lower end of the outer side of the delivery tube 4, so that when the delivery tube 4 rotates, the flocculant can be thrown out of the delivery tube 4. A conical seat 32 is connected to the bottom end of the delivery tube 4. The setting of the conical seat 32 structure improves the efficiency of flocculant delivery and avoids the accumulation of flocculant in the delivery tube 4.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the unloading mechanism includes a worm gear 16, which is rotatably connected to one side of the worm 13. The worm gear 16 and the worm 13 are meshed with each other. When the worm 13 rotates, it can synchronously drive the worm gear 16 to rotate. The outside of the worm gear 16 is connected to a crank 12, and a connecting bar 6 is rotatably connected to the crank 12. The other end of the connecting bar 6 is rotatably connected to the lifting column 8. The lower end of the storage barrel 9 is connected to a conveying pipe 10, and the lower end of the conveying pipe 10 faces the inside of the delivery barrel 4. When the lower end of the conveying pipe 10 is opened, the flocculant material can freely fall into the delivery barrel 4 under the action of gravity.

[0036] Specifically, such as Figure 3As shown, a clamping frame 25 is connected to the outside of the translation frame 5, and a rotating column 17 is connected to the outside of the worm gear 16. The rotating column 17 is rotatably connected to the clamping frame 25. One end of the clamping frame 25 is fixedly connected to the translation frame 5, and the other end of the clamping frame 25 is annular and sleeved on the rotating column 17. The clamping frames 25 on the left and right sides of the worm gear 16 are used to limit its rotation.

[0037] Specifically, such as Figure 5 As shown, a slot 29 is provided on the conveying pipe 10, and a docking seat 30 is slidably connected to the slot 29. The docking seat 30 is connected to the sleeve 3 through the separation frame 11, wherein the conveying pipe 10 structure is fixed, and the docking seat 30 structure can be raised and lowered. When the docking seat 30 descends, the lower end of the conveying pipe 10 opens and the material falls, and when the docking seat 30 rises, the lower end of the conveying pipe 10 is closed, thereby preventing the material from continuing to fall, thereby completing the intermittent feeding operation of the flocculant.

[0038] To sum up, the sewage treatment equipment for municipal water supply and drainage provided in this embodiment needs to add flocculants to the sewage at the initial stage of treatment when municipal sewage needs to be treated uniformly, so that the fine suspended particles and colloidal substances in the sewage that are originally difficult to precipitate can aggregate to form larger flocs, accelerate their sedimentation rate, achieve efficient solid-liquid separation, and significantly reduce the turbidity of the sewage.

[0039] A corresponding steel section 1 structure is installed on the water reservoir where sewage is placed. In the case of a large-area water reservoir, multiple steel sections 1 can be set to ensure that the sewage treatment device can cover the entire water reservoir. In the initial state, the delivery tube 4 is set at one end of the steel section 1. In the initial stage of sewage treatment, a sufficient amount of flocculant particles needs to be placed in the storage tube 9, and then the motor 24 is started. The motor 24 is used to drive the worm 13 to rotate. When the worm 13 rotates, it can synchronously drive the plug 27 and the worm wheel 16 to rotate.

[0040] When the worm gear 16 rotates, it can drive the crank handle 12 connected to the outside of the worm gear 16 to rotate, thereby driving the connecting bar 6 connected to one end of the crank handle 12 to move, and utilizing the connecting bar 6 to pull the lifting column 8 to slide in the slide groove 22, so that the lifting column 8 is vertically lifted. When the height of the lifting column 8 rises, it can drive the deflection rod 14 to rise, thereby causing the propulsion plate 15 to deflect, changing the position where the lower end of the propulsion plate 15 abuts on the moving tooth 2. When the height of the lifting column 8 drops, it can rely on the state where the propulsion plate 15 abuts on the moving tooth 2, thereby pushing the lifting frame 7 and the translation frame 5 to move horizontally, and the moving direction is the direction away from the lower end of the propulsion plate 15.

[0041] When the hopper 10 is lowered, the hopper 10 is in a closed position and the hopper 10 is in a closed position, so that the hopper 10 can be discharged from the hopper 10 and discharged from the hopper 10.

[0042] When the plug block 27 rotates, it can cooperate with the docking post 34 to synchronously drive the docking post 34 to rotate. Since the docking post 34 itself will rise and fall, during the lifting process, the docking post 34 always maintains a clamping state with the plug block 27. The rotation of the docking post 34 drives the delivery barrel 4 to rotate, and the flocculant in the delivery barrel 4 can be thrown out by rotating centrifugation, so that the flocculant particles are thrown out in a circular shape from the discharge port 21. Since the flocculant is delivered in a rotating manner during the lifting process, the coverage range of the flocculant delivery is greatly improved, thereby ensuring that the flocculant can pre-treat sewage in a larger range. The intermittent delivery method to the delivery barrel 4 is adopted instead of adding a sufficient amount of flocculant in the delivery barrel 4, so as to avoid the problem of flocculant blocking the discharge port 21. Quantitative delivery can also accurately control the amount of flocculant delivered to the delivery barrel 4, thereby improving the uniformity of sewage treatment.

[0043] This equipment can precisely address the pain points of existing flocculant delivery technologies, such as insufficient coverage, uneven delivery, and easy clogging. Through the innovative design of a steel track and rotary delivery, it achieves comprehensive coverage of large-scale water reservoirs. Its unique intermittent feeding and alternating motion mechanism not only ensures the uniformity of flocculant delivery, but also effectively avoids the problem of drug accumulation and clogging. Compared with traditional equipment, this device not only significantly improves the efficiency and quality of sewage treatment, but also reduces drug waste and maintenance costs. It provides an efficient, intelligent, and economical solution for the field of municipal water supply and drainage sewage treatment, and has effectively promoted the innovation and development of sewage treatment technology.
