Description

Technical Field

[0001] This utility model relates to the field of sewage treatment agitators, specifically a sewage treatment agitator that can prevent adhesion to the inner wall. Background Technology

[0002] Wastewater treatment mixers are devices used in wastewater treatment facilities, primarily for mixing and homogenizing wastewater to improve treatment efficiency. Through mechanical or pneumatic agitation, they promote full contact between suspended solids and sludge in the wastewater and the treatment agents, enhancing reaction efficiency. Effective agitation not only improves treatment efficiency but also reduces energy consumption, making it an indispensable piece of equipment in modern wastewater treatment systems.

[0003] However, existing wastewater treatment mixers require pre-filtration of wastewater using other equipment, but the filtered wastewater still contains some small particulate impurities, including some viscous impurities. These impurities adhere to the inner wall of the mixer's tank, solidify over time, and are difficult to clean. Existing wastewater treatment mixers usually have scrapers that rotate along the edge of the mixing rod, but the rotational resistance of the scrapers is high and the cleaning efficiency is not high. Therefore, the current wastewater treatment mixers need to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a sewage treatment mixer that can prevent adhesion to the inner wall, in order to solve the problem mentioned in the background art that the sewage treatment mixers on the market usually have a scraper that rotates along the edge of the mixing rod, but the scraper has high rotational resistance and low cleaning efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment agitator that prevents adhesion to the inner wall, comprising an agitator and an agitator rod. A motor is installed in the middle of the agitator. The agitator rod is installed in the inner cavity of the agitator through a bearing, and the agitator rod and the motor are connected by a coupling. A drain outlet is connected to one side of the agitator. A scraping mechanism is installed inside the agitator near the agitator rod, and one side of the scraping mechanism is connected to the agitator rod. The scraping mechanism includes a traction plate fixedly sleeved with the agitator rod. A rotating shaft is installed at the end of the traction plate away from the agitator rod through a bearing. A gear is fixedly sleeved at the top of the rotating shaft. A toothed ring is fixedly installed on the inner wall of the agitator near the top of the gear, and the toothed ring and the gear are meshed. The toothed ring is located outside the agitator rod. A scraper blade is sleeved on the outside of the rotating shaft.

[0006] Preferably, a water inlet is connected to the top of the mixing tank, and an installation mechanism is provided at the bottom of the mixing tank.

[0007] Preferably, the inner walls on both sides of the rotating shaft are provided with docking grooves, and the scraper is connected to a docking block near the inner side of the docking groove, and the docking block and the docking groove are slidably connected.

[0008] Preferably, a round rod is fixed to the bottom end of the rotating shaft, and an abutment cylinder is provided near the bottom end of the round rod of the scraper. A threaded hole is provided in the middle of the abutment cylinder, and an annular groove is provided on the inner wall of the scraper near the abutment cylinder.

[0009] Preferably, the installation mechanism includes an installation ring that is fixedly sleeved on the outside of the bottom end of the mixing tank, and a base plate is provided at the bottom end of the mixing tank and the installation ring. A sealing ring is fixedly installed on the upper surface of the base plate near the outside of the installation ring.

[0010] Preferably, the mounting ring is connected to the chassis by annularly distributed bolts, and an adsorption layer is installed on the chassis above the inner cavity of the mixing tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Equipped with a scraping mechanism and a contact cylinder, the motor drives the stirring rod to rotate, which in turn drives the traction plate to rotate. The traction plate then drives the gear to rotate around the stirring rod in a circular motion. Simultaneously, the gear meshes with the gear ring, causing the gear to rotate on its own axis while rotating in a circular motion. Subsequently, the gear drives the rotating shaft to rotate, which in turn drives the scraper to rotate and scrape the inner wall of the mixing tank. This prevents impurities from adhering to the inner wall of the mixing tank and avoids solidification. The rotation of the scraper reduces rotational resistance and minimizes wear, resulting in high cleaning efficiency. The rotation of the scraper can also cooperate with the stirring of the stirring rod to enhance the flowability of sewage, thus improving the practicality of the sewage mixer.

[0013] 2. Equipped with an installation mechanism, the chassis can be periodically removed from the mounting ring using bolts. Pulling the chassis then allows the adsorption layer to detach from the mixing tank, facilitating the cleaning of impurities on the surface of the adsorption layer. The sealing ring seals the gap between the chassis and the mounting ring. The detachable chassis design improves the convenience of the wastewater treatment mixer. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a sewage treatment agitator that can prevent adhesion to the inner wall, including a mixing tank 1 and a mixing rod 5. A motor 3 is installed in the middle of the mixing tank 1. The mixing rod 5 is installed in the inner cavity of the mixing tank 1 through a bearing, and the mixing rod 5 and the motor 3 are connected by a coupling. A drain outlet 4 is connected to one side of the mixing tank 1, and a water inlet 2 is connected to the top of the mixing tank 1.

[0024] Please see Figure 2 , Figure 3 and Figures 5-7A scraping mechanism 8 is installed inside the mixing tank 1 near the mixing rod 5, and one side of the scraping mechanism 8 is connected to the mixing rod 5. The scraping mechanism 8 includes a traction plate 801 fixedly sleeved with the mixing rod 5. A rotating shaft 803 is mounted on the end of the traction plate 801 away from the mixing rod 5 via a bearing. A gear 802 is fixedly sleeved on the top end of the rotating shaft 803. A gear ring 804 is fixedly sleeved on the inner wall of the mixing tank 1 near the top end of the gear 802, and the gear ring 804 and the gear 802 are meshed. The gear ring 804 is located outside the mixing rod 5. A scraper 80 is sleeved on the outside of the rotating shaft 803. 5. The inner walls on both sides of the rotating shaft 803 are provided with mating grooves 7. The inner side of the scraper 805 near the mating grooves 7 is connected to a mating block 13, and the mating block 13 and the mating grooves 7 are slidably sleeved. The bottom end of the rotating shaft 803 is fixed with a round rod 9. The bottom end of the scraper 805 near the round rod 9 is provided with an abutment cylinder 11. The middle part of the abutment cylinder 11 is provided with a threaded hole 10. The inner wall of the scraper 805 near the abutment cylinder 11 is provided with an annular groove 12. The round rod 9 and the threaded hole 10 are threadedly sleeved. The inner wall of the scraper 805 is provided with several through holes for water flow.

[0025] In practice, during wastewater treatment, the wastewater and treatment agent are mixed using a mixer. This allows the treatment agent to decompose toxic substances in the wastewater. The filtered wastewater contains small particulate impurities, some of which are viscous. These impurities adhere to the inner wall of the mixer's drum, solidifying over time and becoming difficult to clean. To address this, the motor 3 drives the mixing rod 5 to rotate, which in turn drives the traction plate 801 to rotate. The traction plate 801 then drives the gear 802 to rotate around the mixing rod 5. Simultaneously, the gear 802 meshes with the gear ring 804, causing the gear 802 to rotate in a circular motion. Simultaneously, it rotates, and then gear 802 drives rotating shaft 803 to rotate. Rotating shaft 803 then drives scraper 805 to rotate and scrape on the inner wall of mixing tank 1. This can prevent impurities from adhering to the inner wall of mixing tank 1 and avoid the solidification of impurities. When cleaning and replacing scraper 805, the abutment cylinder 11 can be rotated to disengage from annular groove 12, so that the abutment cylinder 11 drives threaded hole 10 to engage with round rod 9. Then threaded hole 10 disengages from round rod 9, and then scraper 805 is pulled down to drive docking block 13 to disengage from docking groove 7. This facilitates quick disassembly and improves the practicality of sewage mixer.

[0026] Please see Figures 1-4The bottom end of the mixing tank 1 is provided with an installation mechanism 6. The installation mechanism 6 includes an installation ring 604 fixedly sleeved on the outside of the bottom end of the mixing tank 1. The bottom end of the mixing tank 1 and the installation ring 604 is provided with a base plate 602. A sealing ring 603 is fixedly installed on the upper surface of the base plate 602 near the outside of the installation ring 604. The installation ring 604 and the base plate 602 are connected by annularly distributed bolts. An adsorption layer 601 is installed on the upper part of the base plate 602 near the inner cavity of the mixing tank 1. The adsorption layer 601 is selected as an activated carbon plate.

[0027] In practical implementation, during sewage treatment, after the sewage is stirred, it will settle in the tank of the mixer for a certain period of time. After the impurities settle at the bottom of the tank for a long time, they are not easy to clean. The base plate 602 can be removed from the mounting ring 604 by bolts at regular intervals. Then, the base plate 602 can be pulled to make the adsorption layer 601 detach from the mixing tank 1, which makes it easier to clean the impurities on the surface of the adsorption layer 601. The sealing ring 603 seals the gap between the base plate 602 and the mounting ring 604. The detachable design of the base plate 602 improves the convenience of the sewage treatment mixer.

[0028] Working principle: When using this sewage treatment mixer that prevents internal wall adhesion, sewage and treatment agent first enter the mixing tank 1 through the inlet 2. Then, the motor 3 is started, which drives the mixing rod 5 to rotate. At the same time, the mixing rod 5 drives the scraping mechanism 8 to clean the inner wall of the mixing tank 1 to prevent impurities from adhering. Subsequently, the chassis 602 is periodically disassembled through the installation mechanism 6 for easy cleaning, which improves the practicality and convenience of the sewage treatment mixer. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
