Description

Technical Field

[0001] This invention relates to the field of odor extraction technology in wastewater treatment, specifically to a mobile odor extraction hood for wastewater treatment. Background Technology

[0002] Domestic sewage and industrial wastewater often contain components such as proteins and sulfur-containing chemical raw materials. During the collection, transportation and treatment of sewage, especially in anaerobic environments, these organic substances are decomposed and metabolized by microorganisms, producing compounds with strong odors.

[0003] These odors contain harmful components such as hydrogen sulfide and ammonia. Long-term exposure to these odors can cause hydrogen sulfide to irritate the respiratory mucosa, leading to symptoms such as coughing and wheezing. In severe cases, high concentrations of hydrogen sulfide may also affect the nervous system.

[0004] Current methods for treating odors involve installing pumps near the wastewater treatment pond to extract and remove the odors generated during the treatment process. However, directly using pumps to extract air from the open-air wastewater treatment pond results in higher air extraction efficiency due to the larger volume of air drawn. While a sealed exhaust system with a cover over the pond is an option, the need for air during treatment negatively impacts the overall effectiveness. Furthermore, the fixed odor extraction pipes cannot be used to target specific odor sources based on their location. Summary of the Invention

[0005] To address the aforementioned issues, a mobile odor extraction hood for wastewater treatment is provided. A movable frame, propelled by a push arm, extracts odors according to different stages of wastewater treatment. Combined with a foldable rainproof cloth that temporarily intercepts diffused odors, the efficiency of odor extraction is improved. This effectively prevents the wastewater treatment tank from being sealed for extended periods during odor extraction, achieving both dispersion and targeted extraction of odors for better results. A flexible hose connects the movable frame to the extraction pipe, and a connecting rod at the push arm adjusts the position of the hose to prevent it from stacking during use.

[0006] To address the problems of existing technologies, the present invention provides a mobile sewage treatment odor extraction hood, which is installed above the sewage treatment tank to extract odor generated during the sewage treatment process. It includes an air extraction pump and an extraction pipe used in conjunction with the air extraction pump. It also includes a mounting bracket that is fixedly installed on top of the sewage treatment tank; It also includes two movable frames that are set above the sewage treatment tank and move along the length of the sewage treatment tank. The two movable frames are symmetrically arranged on both sides of the mounting frame, and a foldable rainproof cloth is provided between each movable frame and the mounting frame. A push arm is also provided between the two movable frames to move the movable frames along the length of the sewage treatment tank; The air pump is installed on the top of the mounting frame. The air pump is provided with an air intake port and an air exhaust port. The air intake pipe extends vertically upward and passes through the mounting frame to connect with the air intake port.

[0007] Preferably, the mounting frame and each movable frame have an open-bottomed air extraction chamber inside, and the air extraction pipe is coaxially arranged with the mounting frame, with the bottom of the air extraction pipe connected to the air extraction chamber inside the mounting frame through a connecting pipe.

[0008] Preferably, the lower end of the suction pipe is further provided with a suction branch pipe, and the suction branch pipe is connected to the suction chamber at the movable frame through a flexible hose. The outer side of the suction pipe is also fitted with a sliding seat that can move vertically along the outer wall of the suction pipe.

[0009] Preferably, the outer side of the sliding seat and the top of the movable frame are both provided with pins, and the outer side of the sliding seat and the top of the movable frame are hinged to the push arm through the pins. The push arm is provided in two sets with the vertical plane of the mounting frame as the symmetrical plane.

[0010] Preferably, the sliding seat has a vertical through-hole threaded groove, and the mounting bracket is also provided with a drive mechanism that cooperates with the sliding seat and its internal threaded groove.

[0011] Preferably, a connecting rod for supporting the hose is installed between the mounting bracket and the push arm, and the hose and the push arm can move synchronously with the push arm.

[0012] Preferably, the mounting frame and the movable frame are further provided with a mounting groove communicating with the air extraction chamber, and a filter plate that works in conjunction with the mounting groove is also provided at the mounting frame and the movable frame.

[0013] Preferably, the vertical cross-sections of both the air extraction chamber and the filter plate are trapezoidal.

[0014] The advantages of this invention compared to the prior art are: 1. The movable frame can be pushed by the push arm to perform mobile odor extraction according to different stages of sewage treatment. At the same time, it works with the foldable rainproof cloth that can temporarily intercept the spread of odor, which improves the efficiency of odor extraction and effectively prevents the odor from spreading further.

[0015] 2. The movable design of the mobile frame effectively prevents the sewage treatment tank from being sealed for a long time during the odor extraction process. It saves time and effort during operation and does not affect the sewage treatment work. It also enables the dispersion and targeted extraction of odors, resulting in better extraction effect.

[0016] 3. The movable frame and the suction pipe are connected by a flexible hose, and the linkage at the push arm will adjust the position of the hose to prevent the hose from stacking during use, thus ensuring the hose's effectiveness in extracting odors. Attached Figure Description

[0024] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1 As shown, a mobile sewage treatment odor extraction hood is installed above the sewage treatment tank to extract odor generated during the sewage treatment process. It includes an air extraction pump 1 and an extraction pipe 2 used in conjunction with the air extraction pump 1.

[0026] The air pump 1 is installed on the top of the mounting frame 3. The air pump 1 is provided with an air intake port and an air exhaust port. The air extraction pipe 2 extends vertically upward and passes through the mounting frame 3 to connect with the air intake port.

[0027] It should be noted that when using the pump, connect the exhaust port of the air pump 1 to the outlet pipe, start the air pump 1, and the air pump 1 can guide the odor generated in the sewage treatment tank to the exhaust port through the air suction pipe 2 at the air suction port and then export and collect it through the outlet pipe.

[0028] See Figure 1-4 As shown, it also includes a mounting bracket 3 that is fixedly installed on the top of the sewage treatment tank; It also includes two movable frames 4 that are set above the sewage treatment tank and move along the length of the sewage treatment tank. The two movable frames 4 are symmetrically arranged on both sides of the mounting frame 3, and a foldable rainproof cloth 5 is provided between each movable frame 4 and the mounting frame 3. A push arm 6 is also provided between the two movable frames 4 to move the movable frames 4 along the length of the sewage treatment tank.

[0029] It should be noted that, depending on the sewage treatment situation in the sewage treatment pond, when the odor gradually dissipates, the push arm 6 pushes the movable frame 4 to move and unfold the foldable rainproof cloth 5 along the length of the sewage treatment pond, thereby intercepting and extracting the odor emitted during the sewage treatment process.

[0030] See Figure 2-4 As shown, the mounting frame 3 and each movable frame 4 have an open-bottomed air extraction chamber inside. The air extraction pipe 2 is coaxially arranged with the mounting frame 3, and the bottom of the air extraction pipe 2 is connected to the air extraction chamber inside the mounting frame 3 through a connecting pipe.

[0031] The lower end of the air extraction pipe 2 is also provided with an air extraction branch pipe 2a, and the air extraction branch pipe 2a is connected to the air extraction chamber at the movable frame 4 through a flexible hose 2a1.

[0032] It should be noted that when extracting odors, the extraction pipe 2 will extract odors from the area below the mounting bracket 3 through the connecting pipe, and the extraction branch pipe 2a and the flexible hose 2a1 will extract odors from the area below the moved location, thus achieving dispersion and targeted extraction of odors, resulting in better extraction effect.

[0033] See Figure 4 and Figure 5 As shown, a sliding seat 2b that can move vertically along the outer wall of the air extraction pipe 2 is also fitted on the outside of the air extraction pipe 2.

[0034] The outer side of the sliding seat 2b and the top of the movable frame 4 are both provided with pins, and the outer side of the sliding seat 2b and the top of the movable frame 4 are hinged to the push arm 6 through the pins. The push arm 6 is provided in two sets with the vertical plane passing through the mounting frame 3 as the symmetrical plane.

[0035] It should be noted that the sliding seat 2b is used to limit the movement position of the push arm 6, which can ensure the stability of the push arm 6 during movement.

[0036] See Figure 1 , Figure 4 and Figure 5 As shown, the sliding seat 2b has a vertical through-hole threaded groove, and the mounting bracket 3 is also provided with a drive mechanism that works in conjunction with the sliding seat 2b and its internal threaded groove.

[0037] It should be noted that the drive mechanism consists of a drive motor, a reduction gear used in conjunction with the drive motor, a threaded rod, and a coupling connecting the threaded rod to the output end. In use, the drive motor and the reduction gear drive the threaded rod to rotate through the coupling, which interacts with the threaded groove in the sliding seat 2b, thereby driving the sliding seat 2b to move along the outer wall of the suction pipe 2, which in turn drives the push arm 6 to push the movable frame 4 to move.

[0038] See Figure 5 As shown, a connecting rod 6a for supporting the hose 2a1 is installed between the mounting bracket 3 and the push arm 6. The hose 2a1 and the push arm 6 can move synchronously with the push arm 6.

[0039] It should be noted that the connecting rod 6a at the push arm 6 will adjust the position of the hose 2a1 to prevent the hose 2a1 from stacking during use, thereby ensuring the extraction effect of the hose 2a1 on odor.

[0040] See Figure 2 - Figure 4 and Figure 6 As shown, the mounting frame 3 and the movable frame 4 are also provided with mounting grooves that communicate with the air extraction chamber, and the mounting frame 3 and the movable frame 4 are also provided with filter plates 7 that cooperate with the mounting grooves.

[0041] Both the air extraction chamber and the filter plate 7 have trapezoidal vertical cross-sections.

[0042] It should be noted that the filter plate 7 installed inside the extraction chamber prevents tiny impurities near the sewage treatment tank from being sucked into the pipes during the extraction of odorous gases, thus avoiding the problem of these impurities accumulating and clogging the pipes over time. The trapezoidal design of the extraction chamber allows for better guidance of odorous gases into its interior, facilitating the extraction pipe 2 to remove them. The trapezoidal design of the filter plate 7 ensures close contact with the inner wall of the extraction chamber, guaranteeing effective filtration of other impurities in the odorous gases.

[0043] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
