Abstract
Description
Technical Field
[0001] This invention belongs to the field of wastewater treatment technology, and specifically relates to a wastewater treatment reactor that facilitates water, gas and solid separation. Background Technology
[0002] Wastewater treatment refers to the process of purifying wastewater containing pollutants through physical, chemical, and biological means to meet discharge standards or reuse requirements. Its core objective is to remove harmful substances from wastewater, reduce pollution to natural water bodies, protect the ecological environment, and achieve the recycling of water resources.
[0003] In wastewater treatment, gas-solid-liquid separation is a core process, and its efficiency directly affects subsequent treatment results and operating costs. Traditionally, static bar screens are widely used due to their simple structure and low cost. While static bar screens can filter and separate wastewater, solids in the wastewater easily clog them. Currently, to address this issue, vibrating pumps are often installed on the bar screens to reduce the risk of clogging. However, filtered solids still accumulate on the screen, and with prolonged operation, these residues can cause further localized clogging. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Summary of the Invention
[0004] The purpose of this invention is to overcome the limitations of static screens, which are widely used in the prior art due to their simple structure and low cost. Although static screens can also filter and separate wastewater, solids in the wastewater can easily clog the screens. Currently, to solve this problem, vibrating pumps are often installed on the screens to reduce the risk of clogging. However, the filtered solids will still accumulate on the screens, and as the operating time increases, the solid residues will cause local clogging of the screens again. This invention aims to provide a wastewater treatment reactor that facilitates the separation of water, gas, and solids.
[0005] To achieve the above-mentioned objectives, the technical solution of this invention is: a wastewater treatment reactor that facilitates water-gas-solid separation, comprising a frame, a shell, and an inlet. The shell is fixedly mounted on the upper end of the frame, and an inlet is provided on one side of the shell. The reactor is characterized in that: a cylindrical screen is rotatably mounted inside the shell; mounting frames are fixedly mounted at both ends of the frame away from the inlet; several mounting shafts are rotatably mounted on each mounting frame; each adjacent mounting shaft is connected by gear meshing; rollers are fixedly mounted on two mounting shafts to drive the cylindrical screen to rotate; a drive mechanism is mounted on the frame to drive one of the mounting shafts; and a cleaning mechanism for cleaning the cylindrical screen is mounted on the upper interior of the shell. The cleaning mechanism includes two fixed shafts fixedly connected to the inner wall of the shell and ear plates mounted on each fixed shaft; a cleaning brush for cleaning the cylindrical screen is rotatably mounted between the two ear plates.
[0006] In the above-mentioned wastewater treatment reactor that facilitates water-gas-solid separation, each of the mounting frames is L-shaped, and the two rollers are located at both ends of the mounting frame.
[0007] In the above-mentioned wastewater treatment reactor that facilitates water-gas-solid separation, the drive mechanism includes a driven pulley fixedly mounted on one of the mounting shafts and a drive motor fixedly mounted on the frame. The output shaft of the drive motor is fixedly mounted with a driving pulley, and the driving pulley and the driven pulley are connected by a transmission belt.
[0008] In the aforementioned wastewater treatment reactor that facilitates water, gas, and solid separation, each of the idlers is wrapped with a rubber pad.
[0009] In the aforementioned wastewater treatment reactor that facilitates water-gas-solid separation, an auxiliary roller is fixedly mounted on one of the mounting shafts to drive the cylindrical screen to rotate, and the auxiliary roller is located on the side away from the support roller.
[0010] In the above-mentioned wastewater treatment reactor that facilitates water-gas-solid separation, there are two cleaning mechanisms. Each fixed shaft has a retaining ring fixedly connected to its lower end, and each ear plate is slidably connected to the corresponding fixed shaft. Each fixed shaft is fitted with a spring, one end of which is fixedly connected to the retaining ring and the other end of which is fixedly connected to the ear plate.
[0011] In the above-mentioned wastewater treatment reactor that facilitates water-gas-solid separation, an adjusting plate is fixedly connected between the two ear plates, and a threaded rod that can compress the adjusting plate is threadedly connected to the shell through a threaded hole.
[0012] In the aforementioned wastewater treatment reactor that facilitates water, gas, and solid separation, a waterproof motor capable of driving a cleaning brush to rotate is fixedly installed on one of the ear plates.
[0013] Compared with the prior art, the wastewater treatment reactor of the present invention, which facilitates water-gas-solid separation, has at least the following beneficial effects: 1. The present invention provides a wastewater treatment reactor that facilitates solid-water-gas-solid separation. Through the use of a cylindrical screen, solid-liquid separation of wastewater can be achieved, while gas can be discharged from the inlet. The ingenious design of the mounting frame, mounting shaft, gears, rollers, and drive mechanism allows the cylindrical screen to rotate. Wastewater is thrown onto the surface of the cylindrical screen under centrifugal force, solids are trapped due to inertia, while water is quickly discharged through the screen holes. This not only effectively separates solids and liquids but also reduces clogging. This dynamic screen is more efficient than a static screen and can significantly improve solid-liquid separation efficiency.
[0014] 2. The wastewater treatment reactor of the present invention facilitates water-gas-solid separation. Through the ingenious design of the fixed shaft, ear plate and cleaning brush, the dynamic cylindrical screen can be cleaned in real time, further reducing clogging. Furthermore, through the design of the retaining ring and spring, the cleaning brush can automatically adjust its position and always keep close to the surface of the cylindrical screen, avoiding cleaning blind spots caused by the deformation of the cylindrical screen. This design, through the dual mechanism of mechanical linkage and elastic compensation, not only ensures the continuity of cleaning action, but also improves the adaptability to complex working conditions, providing a reliable guarantee for the efficiency and stability of solid-liquid separation in wastewater treatment.

[0019] This embodiment discloses a wastewater treatment reactor that facilitates solid-water-gas-solid separation. Through the arrangement of a cylindrical screen 3, solid-liquid separation of wastewater can be achieved, while gas can be discharged from the inlet 201, thus realizing separation. Through the ingenious design of the mounting frame 4, mounting shaft 5, gear 7, idler roller 6, and drive mechanism 9, the cylindrical screen 3 can be rotated. Wastewater is thrown onto the surface of the cylindrical screen 3 under centrifugal force, solids are trapped due to inertia, while water is quickly discharged through the screen holes. This not only effectively separates solids and liquids but also reduces clogging. This dynamic screen is more efficient than a static screen and can significantly improve solid-liquid separation efficiency. (Refer to...) Figures 1-7It mainly includes a frame 1, a housing 2, and a liquid inlet 201. The housing 2 is fixedly installed on the upper end of the frame 1, and the liquid inlet 201 is provided on one side of the housing 2. The key feature is that a cylindrical screen 3 is rotatably installed inside the housing 2. Mounting frames 4 are fixedly installed at both ends of the side of the frame 1 away from the liquid inlet 201. Several mounting shafts 5 are rotatably installed on each mounting frame 4. Each adjacent mounting shaft 5 is connected by a gear 7. Rollers 6 are fixedly installed on two mounting shafts 5 to drive the cylindrical screen 3 to rotate. A drive mechanism 9 is installed on the frame 1 to drive one of the mounting shafts 5. A cleaning mechanism for cleaning the cylindrical screen 3 is installed at the upper part of the inner side of the housing 2. The cleaning mechanism includes two fixed shafts 13 fixedly connected to the inner wall of the housing 2 and ear plates 10 installed on each of the fixed shafts 13. A cleaning brush 11 for cleaning the cylindrical screen 3 is rotatably installed between the two ear plates 10. Through the ingenious design of the fixed shafts 13, ear plates 10 and cleaning brush 11, the dynamic cylindrical screen 3 can be cleaned in real time, further reducing clogging.
[0020] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Each of the mounting frames 4 is L-shaped, and the two rollers 6 are located at both ends of the mounting frame 4 respectively. The arrangement of the rollers 6 at both ends of the L-shaped mounting frame 4 can form a more stable axis of rotation. Even if there are slight manufacturing errors or uneven gravity distribution in the cylindrical screen 3, dynamic balance can be maintained through the synergistic effect of the rollers 6 at both ends, reducing the vibration of the cylindrical screen 3.
[0021] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The drive mechanism 9 includes a driven pulley 901 fixedly mounted on one of the mounting shafts 5 and a drive motor 904 fixedly mounted on the frame 1. The output shaft of the drive motor 904 is fixedly mounted with a drive pulley 903. The drive pulley 903 and the driven pulley 901 are connected by a transmission belt 902. In practical use, the drive motor 904 is started, which drives the active pulley 903 to rotate. Through the design of the transmission belt 902, the driven pulley 901 rotates, and the driven pulley 901 drives the corresponding mounting shaft 5 to rotate.
[0022] In this embodiment, each of the idler rollers 6 is wrapped with a rubber pad; this can increase the friction between the idler rollers 6 and the cylindrical screen 3, thereby preventing the cylindrical screen 3 from slipping due to inertia during rotation.
[0023] In this embodiment, refer to Figure 1 and Figure 3 An auxiliary roller 601 is fixedly mounted on one of the mounting shafts 5 to drive the cylindrical screen 3 to rotate, and the auxiliary roller 601 is located on the side away from the support roller 6; the auxiliary roller 601 works with the support roller 6 to drive the cylindrical screen 3 to rotate through friction, thereby enabling the cylindrical screen 3 to rotate more effectively.
[0024] In this embodiment, refer to Figure 6 and Figure 7 The cleaning mechanism consists of two parts. Each fixed shaft 13 has a retaining ring 1301 fixedly connected to its lower end. Each ear plate 10 is slidably connected to the corresponding fixed shaft 13. Each fixed shaft 13 is fitted with a spring 14. One end of the spring 14 is fixedly connected to the retaining ring 1301, and the other end is fixedly connected to the ear plate 10. In practical use, the spring 14 allows the cleaning brush 11 on the ear plate 10 to be in close contact with the cylindrical screen 3, thereby cleaning the cylindrical screen 3 better and effectively reducing the clogging of the cylindrical screen 3.
[0025] In this embodiment, refer to Figure Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 An adjusting plate 15 is fixedly connected between the two ear plates 10. A threaded rod 8 that can compress the adjusting plate 15 is threadedly connected to the housing 2 through a threaded hole. With the setting of the adjusting plate 15 and the threaded rod 8, the distance between the cleaning brush 11 and the cylindrical screen 3 can be adjusted as needed, so as to better clean the cylindrical screen 3 as needed.
[0026] In this embodiment, refer to Figure 6 and Figure 7 One of the ear plates 10 is fixedly mounted with a waterproof motor 12 that can drive the cleaning brush 11 to rotate; by setting the waterproof motor 12, the cleaning brush 11 can be rotated as needed, thereby better cleaning the cylindrical screen 3.
[0027] The working principle of a wastewater treatment reactor for easy water-gas-solid separation according to the present invention is as follows: When treating wastewater, the wastewater flows into the cylindrical screen 3 inside the shell 2 through the inlet 201. The cylindrical screen 3 can filter and separate solids and liquids, while gas can be discharged from the inlet 201, thus achieving water-gas-solid separation. During the separation process, the drive motor 904 is started, which drives the active pulley 903 to rotate. Through the cooperation of the transmission belt 902, the driven pulley 901 rotates, which drives the corresponding mounting shaft 5 to rotate. Through the meshing of the gears 7, the corresponding mounting shaft 5 rotates, which drives the roller 6 to rotate, thereby causing the cylindrical screen 3 to rotate. This not only effectively separates solids and liquids but also reduces clogging. During the rotation of the cylindrical screen 3, the waterproof motor 12 is started, which drives the cleaning brush 11 to rotate, thereby allowing the cleaning brush 11 to clean the cylindrical screen 3, further reducing clogging.
