Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment and filtration, in particular to a self-cleaning sewage treatment filtration device. Background Art

[0002] The filtration device for sewage treatment is a key component in the sewage treatment system. Its main function is to remove impurities such as suspended matter and particulate matter in sewage through physical filtration, thereby improving the quality of sewage.

[0003] For example, the patent application number published on the China Patent Network is: 202120438833.1, and the patent name is: A filtering device for river sewage treatment, comprising a base, a filter box is bolted to the top of the base, and the top of the filter box is connected to an inlet pipe, and a bidirectional motor is bolted to the top of the right side of the filter box, and the output end of the bidirectional motor is bolted to a rotating rod, and the outer side of the rotating rod is threadedly connected to a slider, and the bottom of the slider is bolted to a cleaning brush; by designing an easy-to-use bidirectional motor, rotating rod, slider, cleaning brush, filter plate and collection box, it is possible to facilitate the collection and treatment of filtered garbage without manual cleaning, which greatly reduces the burden of use; by designing an easy-to-use purification box, it is possible to filter harmful substances in the sewage, which not only greatly improves the filtering effect, but also can be discharged directly to avoid secondary pollution, and is worthy of popularization and use.

[0004] Since sewage contains a large amount of suspended matter, particulate matter and other impurities, these impurities are easily accumulated inside the filter device, causing blockage. However, the treatment method of the existing filter device is relatively simple. The method of purifying sewage through chemical flocculants will produce a large amount of flocs, which are easy to stick to the surface of the equipment, which not only affects the filtration efficiency of the equipment, but also increases the difficulty of subsequent cleaning. After the flocs stick to the surface of the equipment, manual washing operations are required, which is not only time-consuming and labor-intensive, but may also cause damage to the surface of the equipment. The use of chemical flocculants may leave chemical residues, which may cause secondary pollution to the water quality and may also corrode the equipment material.

[0005] Secondly, when the filter device needs to be emptied after cleaning, the floccules that have settled at the bottom will adhere to it due to their own friction, making it impossible to completely clean it. This not only affects the cleanliness of the equipment, but also affects the subsequent treatment effect. Due to the adhesion of the floccules, the emptying process may not be carried out thoroughly, resulting in residual dirt inside the equipment, which increases the difficulty and cost of subsequent maintenance.

[0006] Finally, the cleaning process requires the use of chemical cleaning agents, high-pressure water guns and other tools, which not only increases the complexity of cleaning, but may also cause damage to the equipment. During the washing process, due to the need for manual operation, it is often impossible to proceed synchronously with the normal operation of the equipment, which reduces the overall efficiency of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 9 As shown, the present invention provides a self-cleaning sewage treatment filtering device, comprising a sewage treatment tank 1;

[0043] A cleaning structure 2 is provided inside the sewage treatment tank 1, and the cleaning structure 2 can scrape off sewage impurities attached to the inner wall of the sewage treatment tank 1. A base 3 is provided at the bottom of the sewage treatment tank 1, and the base 3 is connected to the sewage treatment tank 1 through a supporting structure 4. A transmission structure 5 is provided on the outside of the supporting structure 4, and the transmission structure 5 can drive the cleaning structure 2 to clean the inside of the sewage treatment tank 1 while pushing the supporting structure 4 to swing.

[0044] refer to Figure 3 The cleaning structure 2 is a core component of the self-cleaning sewage treatment filter device. Its main purpose is to efficiently scrape the inner wall of the sewage treatment tank 1 and assist in mixing the sewage and the chemical flocculant evenly. The structure is mainly composed of a shaft 7, a support frame 8, a transmission rod 9, an inclined cone wheel 10, a connecting plate 11 and a scraper 12. The shaft 7 is the main part of the cleaning structure 2. It is horizontally arranged inside the sewage treatment tank 1, and both ends of it penetrate the side wall of the sewage treatment tank 1 and extend to the outside of the tank body, which not only enables the shaft 7 to The shaft 7 is stably supported in the sewage treatment tank 1, and it is also convenient to drive and control the shaft 7 from the outside. A support frame 8 is installed on the surface of the shaft 7. The support frame 8 plays a role in fixing and supporting the transmission rod 9. The design of the support frame 8 enables the transmission rod 9 to be flexibly connected on its surface, thereby realizing the rotation of the transmission rod 9 relative to the shaft 7. The top of the transmission rod 9 and the surface of the shaft 7 are fixedly connected to the inclined cone wheel 10, and the inclined cone wheels 10 are meshed with each other. When the shaft 7 starts to rotate under the drive of the external power, it will pass The meshing action of the inclined cone wheel 10 drives the transmission rod 9 to rotate together, which not only simplifies the transmission mechanism, but also improves the efficiency and stability of the transmission. The bottom end of the transmission rod 9 is fixedly connected to a connecting plate 11, and the bottom of the connecting plate 11 is tightly fitted with the bottom of the inner wall of the sewage treatment tank 1, thereby ensuring that the connecting plate 11 can always keep in contact with the tank wall during the rotation process. Two scrapers 12 are fixedly connected to the top sides of the connecting plate 11 respectively, and the outer sides of the scrapers 12 are tightly fitted with the inner surface of the sewage treatment tank 1, so that the connecting plate 11 can be connected to the inner surface of the sewage treatment tank 1. During the rotation, the tank wall is effectively scraped. When the shaft 7 rotates, the transmission rod 9 is driven to rotate through the bevel wheel 10, and then the connecting plate 11 and the scraper 12 are driven to rotate together. During the rotation, the scraper 12 will continuously scrape off impurities and residues on the inner wall of the sewage treatment tank 1, thereby ensuring the cleanliness of the tank. At the same time, since the connecting plate 11 and the scraper 12 are constantly rotating, they can also play a role in stirring the sewage and the chemical flocculant, so that the two can be more fully mixed and evenly mixed, thereby improving the efficiency and quality of sewage treatment.

The bracket 13 is sleeved on the surface of the sleeve 14 and is movably connected to the sleeve 14. The design of the movable connection enables the bracket 13 to allow the sewage treatment tank 1 to swing to a certain extent while ensuring stability.

[0059] As a technical optimization scheme of the present invention, through the cooperation of the force-bearing rod 40, the reciprocating thread, the screw sleeve 41, the pressure roller 42 and the guide frame 44, the function of controlling the reciprocating swing of the knocking rod 38 during the rotation of the transmission rod 9 is realized, which not only improves the knocking efficiency, but also makes the knocking force more uniform, which helps to extend the service life of the sewage treatment tank 1.

[0060] refer to Figure 8 Both sides of the support frame 8 are fixedly connected with spring plates 43, and the side of the spring plate 43 away from the support frame 8 contacts the surface of the knocking rod 38. The spring plate 43 is elastic. The surface of the transmission rod 9 is sleeved with a guide frame 44. Both ends of the guide frame 44 pass through the screw sleeve 41 and are fixedly connected to the bottom of the support frame 8. The screw sleeve 41 can slide vertically on the surface of the guide frame 44.

[0061] As a technical optimization solution of the present invention, the spring plate 43 plays a role of buffering and supporting the striking rod 38 through its elastic characteristics and contact with the striking rod 38. At the same time, the design of the guide frame 44 enables the screw sleeve 41 to slide vertically on its surface, ensuring the stability and accuracy of the striking rod 38, which helps to improve the durability of the striking rod 38 and the stability of the entire device.

[0062] The working principle and use process of the present invention are as follows: the sewage treatment tank 1 is filled with sewage and flocculant, and the reaction begins. The servo motor 18 in the transmission structure 5 is started to drive the screw 16 to rotate. The screw 16 drives the transmission plate 17 to move up and down, and the shaft 7 is driven to rotate through the meshing of the tooth plate 19 and the gear 20. When the shaft 7 rotates, the transmission rod 9 is driven to rotate through the inclined cone wheel 10, thereby driving the connecting plate 11 and the scraper 12 to rotate inside the sewage treatment tank 1. The scraper 12 scrapes off the sewage impurities attached to the inner wall of the sewage treatment tank 1. At the same time, the rotating connecting plate 11 and the scraper 12 also play a stirring role, thereby improving the contact uniformity between the sewage and the chemical flocculant. During the lifting process of the transmission plate 17, the interaction between the extension rod 22, the slide rod 23 and the fork 21 causes the sewage treatment tank 1 to swing inside the bracket 13, generating an oscillation effect. The oscillation helps to further separate impurities in the sewage and improve the filtering effect. During the rotation of the transmission rod 9, the transmission rod 9 uses the reciprocating thread on the surface to drive the screw sleeve 41 to lift vertically. During the movement of the screw sleeve 41, the pressure roller 42 is used to squeeze the force-bearing rod 40, so that the knocking rod 38 connected to the force-bearing rod 40 reciprocates around the pin shaft on the surface of the movable block 37 as the axis. The knocking rod 38 is controlled by the driving structure 39 during the rotation of the transmission rod 9 to vibrate and strike the surface of the sewage treatment tank 1 to further clean impurities. During the cleaning process, the spray structure 6 starts to work, and the external flushing liquid can enter the spray pipe 26 through the connection of the valve 29, and then enter the sewage treatment tank 1 through the nozzle 27 at the bottom of the spray pipe 26. The spray liquid directly contacts the inner wall of the sewage treatment tank 1 and rinses the scraped stains to make them out of the sticky state. When the transmission plate 17 is lifted and lowered, the transmission energy The vertical plate 32 can be lifted and lowered synchronously, and the pressure rod 33 is driven to slide inside the swing rod 31 during the movement of the vertical plate. The swing rod 31 is squeezed to drive the spray pipe 26 to rotate and swing, and drive the spray pipe 26 to change the spray angle to flush the inside of the sewage treatment tank 1. When the inside of the sewage treatment tank 1 is cleaned, the transmission plate 17 continues to rise. At this time, the tooth plate 19 and the gear 20 are first disengaged, so that the shaft 7 no longer rotates, and the continuously moving extension rod 22 carries the slide rod 23 to move to the bending part of the fork 21. The casing 14 can be used to carry the sewage treatment tank 1 to swing on the inner side of the bracket 13, so that the entire sewage treatment tank 1 is tilted and the residual stains inside are dumped. When the transmission plate 17 continues to rise, it can drive the control rod 34 of the valve 29 to swing through the vertical rod 35 and the push rod 36, close the valve 29, and stop spraying. After dumping, the transmission structure 5 works in the reverse direction to reset the sewage treatment tank 1 to the initial position, and the cleaning structure 2, the transmission structure 5, the spraying structure 6, etc. are also reset to the initial state, ready for the next round of sewage treatment.

[0063] To sum up: the self-cleaning sewage treatment filter device can stir during the reaction between sewage and flocculant, and at the same time vibrate the sewage treatment device and scrape the inside, effectively improving the sewage treatment efficiency and filtration quality, and spraying flushing liquid through the top spray structure 6 to further clean impurities, and after cleaning, the sewage treatment device can be dumped and the amount of flushing liquid entering can be controlled, realizing automated and efficient sewage treatment.
