Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and specifically to a sewage treatment device. Background Technology

[0002] With the acceleration of industrialization and urbanization, the amount of sewage discharge is increasing day by day, and the efficiency and reliability of sewage treatment technology have become key issues that urgently need to be addressed.

[0003] Traditional wastewater treatment technologies commonly involve adding disinfectant powder and flocculant to a wastewater storage container. The disinfectant powder's bactericidal and sterilizing properties, combined with the flocculant's coagulation and sedimentation characteristics, purify the wastewater of impurities and harmful substances to a certain extent. However, the limited size of the wastewater storage container severely restricts the volume of wastewater that can be treated at one time, failing to meet the needs of large-scale wastewater treatment. Furthermore, after disinfection and flocculation, an additional separation process between the purified water and the sediment is required. This process not only adds steps and prolongs the overall treatment time but also consumes significant human and material resources, resulting in low wastewater treatment efficiency. Therefore, we propose a wastewater treatment device to address these issues. Utility Model Content

[0015] Furthermore, the feeding assembly includes an injection cylinder fixedly inserted into the side wall of the L-shaped plate. One end of the injection cylinder is connected to a water inlet pipe. A drive motor is installed at the end of the injection cylinder away from the water inlet pipe.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This application provides a wastewater treatment device, mainly to solve the problem that existing technologies, due to the limited size of wastewater storage containers, severely restrict the amount of wastewater that can be treated at one time, thus failing to meet the needs of large-scale wastewater treatment. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0025] A wastewater treatment device, comprising:

[0026] Mounting slot 1 is a right-angled trapezoid, and the lower side of mounting slot 1 is connected to drainage channel 2;

[0027] The water-passing plate 3 is fixed between the inner side walls of the mounting groove 1. The water-passing plate 3 is wavy and inclined downward.

[0028] The filter element 4 is set at each crest of the water-passing plate 3 for filtering sewage. The filter element 4 includes an installation cylinder 401. The installation groove 1 is constructed with a circular channel 101 corresponding to each crest of the water-passing plate 3. The installation cylinder 401 is slidably inserted into the interior of the circular channel 101. The interior of the installation cylinder 401 is filled with filter media 402. The surface of the installation cylinder 401 is evenly distributed with water leakage holes 4011.

[0029] L-shaped plate 5 is fixed on the top of the higher side of the mounting groove 1, and water inlet pipe 6 is fixedly embedded on the top surface of L-shaped plate 5.

[0030] It also includes a material conveying assembly 7, which is set on the side wall of the L-shaped plate 5. The material conveying assembly 7 is used to continuously convey flocculant and disinfectant powder into the water inlet pipe 6. The material conveying assembly 7 includes an injection cylinder 701 fixedly inserted into the side wall of the L-shaped plate 5. One end of the injection cylinder 701 is connected to the water inlet pipe 6. A drive motor 702 is installed at the end of the injection cylinder 701 away from the water inlet pipe 6. The output shaft of the drive motor 702 passes through the cylinder wall of the injection cylinder 701 and is connected to an installation rod 703. The surface of the installation rod 703 is provided with auger blades 704. The side of the injection cylinder 701 closest to the drive motor 702 is connected to a feed cylinder 705, and a valve 706 is provided at the connection between the two.

[0031] Workflow Description

[0032] Wastewater introduction stage:

[0033] With the help of a pumping device, sewage is continuously introduced into the sewage treatment equipment from the upper port of the inlet pipe 6. At the same time, the conveying component 7 starts to work. Driven by the drive motor 702, the auger blades 704 continuously convey flocculant and disinfectant powder from the feed cylinder 705 into the inlet pipe 6 to mix with the introduced sewage.

[0034] Filtration and sedimentation stage:

[0035] Wastewater mixed with flocculant and disinfectant powder falls onto a wave-shaped, downward-sloping water-passing plate 3. The water-passing plate 3 has multiple troughs and crests, and filter elements 4 are installed at the crests. Wastewater enters the installation cylinder 401 through the leakage hole 4011 and is filtered by the filter media 402. Impurities in the wastewater are intercepted. Under the action of flocculant and disinfectant powder, harmful substances in the wastewater react, and the resulting precipitate remains at the troughs of the water-passing plate 3. As the wastewater continues to flow through the water-passing plate 3 and is filtered by the filter elements 4 at the multiple crests, the wastewater is gradually purified.

[0036] Purified water discharge and cleaning stage:

[0037] After thorough filtration and purification, the wastewater is discharged outward from the drainage channel 2 connected to the lower side of the installation tank 1. After all the wastewater purification work is completed, the filter element 4 (installation cylinder 401) can be disassembled to facilitate the cleaning of the sediment left in the trough of the water plate 3, so that the equipment can carry out the next round of wastewater treatment.

[0038] This device constructs a novel multi-stage filtration structure by setting up a wave-shaped, downward-sloping water-passing plate 3, in conjunction with a filter element 4 placed at the crest of the wave. This allows wastewater to be filtered multiple times during its flow, resulting in rapid and thorough purification. Compared with traditional wastewater treatment technologies, it significantly shortens the treatment time, meets the needs of large-scale wastewater treatment, and reduces the number of treatment steps. Unlike traditional methods, it eliminates the need for additional complex water and sedimentation separation operations after disinfection and flocculation reactions, making it simpler and more efficient. Furthermore, the easy-to-disassemble and install design of the filter element 4 simplifies equipment maintenance, improving its usability and stability.

[0039] like Figure 4As shown, in some embodiments, the filter media 402 is volcanic rock. More specifically, the surface of the volcanic rock is rough and full of pores. These pores are interconnected to form a complex pore network. This unique physical structure gives it a large specific surface area, allowing a unit volume of volcanic rock to provide more adsorption sites. When sewage enters the cylinder through the drainage holes 4011 on the surface of the mounting cylinder 401 and comes into contact with the volcanic rock filter media 402, suspended particles, colloids, and other impurities in the sewage are trapped in the pores and surface of the volcanic rock due to physical interception and adsorption. Moreover, volcanic rock has good chemical stability and mechanical strength, and is not easily corroded or broken during sewage treatment, resulting in a long service life. This reduces the frequency of filter media 402 replacement, lowers equipment maintenance costs and manual operation. Furthermore, volcanic rock is abundant in nature, relatively easy to obtain, and inexpensive. Compared with some artificially synthesized filter media 402, it significantly reduces the procurement cost of filter media 402 while ensuring treatment effect, making the sewage treatment equipment more economical during operation and conducive to large-scale promotion and application.

[0040] like Figure 3 As shown, in some embodiments, a limiting disc 4012 is fixedly provided at one end of the mounting cylinder 401, and a cylinder cover 4013 is threadedly connected to the other end. More specifically, the limiting disc 4012 is fixedly disposed at one end of the mounting cylinder 401, and its size is larger than the inner diameter of the circular channel 101 corresponding to the mounting groove 1. When the mounting cylinder 401 slides through the circular channel 101, the limiting disc 4012 can fit tightly against the surface of the mounting groove 1, playing a limiting role and preventing the mounting cylinder 401 from completely sliding into the mounting groove 1, ensuring that the mounting cylinder 401 is stable in position during the filtration of sewage. The other end of the mounting cylinder 401 is threadedly connected to the cylinder cover 4013 for filling, replacing, and inspecting the filter media 402. This provides great convenience. Before the equipment is put into use, the cylinder cover 4013 can be opened, and the volcanic rock filter media 402 can be filled into the installation cylinder 401. Due to the good sealing of the threaded connection, it can effectively prevent sewage from leaking from the connection of the cylinder cover 4013, ensuring that sewage can only come into contact with the filter media 402 through the water leakage holes 4011 on the surface of the installation cylinder 401, thereby ensuring the filtration effect. As the sewage treatment work continues, when the volcanic rock filter media 402 adsorbs a large amount of impurities or microbial film and reaches a certain saturation, and the filtration effect decreases, the cylinder cover 4013 can be unscrewed, the ineffective filter media 402 can be poured out, and new volcanic rock filter media 402 can be replaced to quickly restore the filtration performance of the installation cylinder 401.

[0041] like Figure 4As shown, in some embodiments, a rubber ring is embedded in the inner wall of the circular channel 101. More specifically, during the sewage treatment process, the sewage flows within the equipment with a certain pressure and velocity. If the seal between the mounting cylinder 401 and the circular channel 101 is not tight, sewage may leak from the gaps, causing some sewage to flow out directly without filtration, which seriously affects the sewage treatment effect and the degree of water purification. When the mounting cylinder 401 slides into the circular channel 101, the outer wall of the mounting cylinder 401 will come into close contact with the rubber ring on the inner wall of the circular channel 101. Under the compression of the two, the rubber ring undergoes elastic deformation, filling the tiny gaps between the mounting cylinder 401 and the circular channel 101, forming a continuous and tight sealing layer. This sealing layer can effectively prevent sewage from leaking from the connection between the mounting cylinder 401 and the circular channel 101, ensuring that sewage can only enter the cylinder through the drainage holes 4011 on the surface of the mounting cylinder 401 and come into contact with the volcanic rock filter media 402, thereby ensuring the effectiveness and stability of the filtration process.
