Description

Technical Field

[0001] This utility model belongs to the technical field of environmental protection equipment connection components, specifically relating to a reverse connector for a leachate vacuum suction device. Background Technology

[0002] In fields such as waste treatment, chemical industry, and environmental protection, the collection and transportation of leachate (containing high concentrations of pollutants, suspended solids, and fibrous impurities) relies on vacuum suction equipment. The connector, as a core connecting component between the equipment and the front-end collection device, directly affects the operating efficiency and stability of the suction system. However, the traditional connectors used in existing leachate vacuum suction equipment have gradually revealed multiple technical defects over long-term use, making it difficult to meet the demands for efficient and stable leachate treatment.

[0003] Leachate has a complex composition, containing a large amount of suspended solids (such as garbage debris and sludge particles) and fibrous impurities (such as plastic filaments and plant fibers). Traditional connectors are mostly single straight-through structures without anti-clogging or active unclogging functions. During use, impurities easily accumulate on the inner wall of the connector and at the interface, forming blockages. Once a blockage occurs, the machine must be stopped immediately and the connector and pipeline must be manually disassembled for cleaning. Therefore, those skilled in the art have provided a reverse connector for a leachate vacuum suction device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a reverse connector for a leachate vacuum suction device that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A reverse connector for a leachate vacuum suction device includes a leachate flow pipe, characterized in that: a leachate suction pipe is connected to the top end of the leachate flow pipe, a sealing pipe is connected to one end of the leachate flow pipe, pneumatic valve assemblies are provided on both the leachate suction pipe and the sealing pipe, and a backflushing assembly that cooperates with the two pneumatic valve assemblies is provided below the leachate flow pipe.

[0007] As a further optimization of this utility model, the backflushing assembly includes a backflushing air valve located below the leachate flow pipe, the output end of the backflushing air valve being connected to a backflushing pipe, and the other end of the backflushing pipe being sealed through the inner wall of the sealing pipe.

[0008] As a further optimization of this utility model, the pneumatic valve assembly includes mounting rings that are fixedly installed on the outer walls of the leachate suction pipe and the sealing pipe, respectively. A servo motor is fixedly installed on the side wall of the mounting ring. The output end of the servo motor rotates through the inner walls of the corresponding leachate suction pipe and the sealing pipe. A valve disc that is rotatably connected to the inner wall of the leachate suction pipe and the sealing pipe is fixedly installed on the output end of the servo motor.

[0009] As a further optimization of this utility model, the axis of the other end of the backflushing pipe is collinear with the axis of the leachate flow pipe.

[0010] As a further optimization of this utility model, the other end of the leachate flow pipe is connected to a connector, and the outer wall of the connector is provided with a threaded groove.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model achieves automatic purging of blockages through the design of "backflush assembly + pneumatic valve collaboration": When the system alarm detects a blockage, the pneumatic valve assembly on the leachate suction pipe and the sealing pipe quickly closes (the servo motor drives the valve disc to cut off the passage), and the backflush valve opens simultaneously. Compressed air is injected in reverse through the backflush pipe (which is colinear with the axis of the flow pipe and has a precise purging direction), directly purging and clearing the blockage from the joint end without manual disassembly.

[0013] 2. In this utility model, the pneumatic valve assembly is driven by a servo motor to rotate the valve disc, which can realize the rapid and tight opening and closing of the pipeline: during normal suction, the valve disc is fully opened to ensure the maximum flow cross section of the leachate and the stable flow rate.

[0014] 3. In this utility model, the valve disc of the pneumatic valve assembly is made of wear-resistant rubber, and each pipeline is made of corrosion-resistant stainless steel, which can withstand long-term erosion by leachate; and the backflushing process is automatically controlled by the system.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1: As Figures 1-4 As shown, a reverse connector for a leachate vacuum suction device includes a leachate flow pipe 1 and matching suction, sealing and backflushing components, which achieve the full-process function of "normal suction - blockage detection - reverse purging" through the coordinated operation of multiple components.

[0022] like Figures 1-4 As shown, the top end of the leachate flow pipe 1 is connected to the leachate suction pipe 3, which is used to connect to the main pipe of the vacuum suction system and transport the sucked leachate to the subsequent treatment unit; one end of the leachate flow pipe 1 is connected to the sealing pipe 6, which serves as the front-end channel for liquid inflow; the other end is connected to the connector 2, and the outer wall of the connector 2 is provided with a threaded groove, which can be quickly connected to the front-end leachate collection device such as the suction pipe or the liquid collection tank interface through threaded connection, ensuring a tight connection and convenient disassembly and assembly.

[0023] like Figures 1-4 As shown, both the leachate suction pipe 3 and the sealing pipe 6 are equipped with pneumatic valve assemblies 4. Each pneumatic valve assembly 4 includes a mounting ring 402 fixedly installed on the outer wall of the corresponding pipe. A servo motor 401 is fixedly installed on the side wall of the mounting ring 402. The output end of the servo motor 401 rotates through the inner wall of the pipe and a valve disc 403 is fixedly installed at its end. The valve disc 403 is rotatably connected to the inner wall of the pipe. When the servo motor 401 drives the valve disc 403 to rotate to be perpendicular to the pipe axis, the pipe is closed; when it rotates to be parallel to the axis, the pipe is open. Through the coordinated action of the two pneumatic valve assemblies 4, the switching between suction and backflushing processes can be controlled.

[0024] like Figures 1-4As shown, a backflushing assembly is provided below the leachate flow pipe 1, which cooperates with the pneumatic valve assembly 4. The backflushing assembly includes a backflushing air valve 5, the output end of which is connected to a backflushing pipe 7. The other end of the backflushing pipe 7 is sealed through the inner wall of the sealing pipe 6, and its axis is collinear with the axis of the leachate flow pipe 1, ensuring that the backflushing airflow can accurately purge along the axial direction of the flow pipe. The backflushing air valve 5 is connected to the air supply device of the vacuum suction system (not shown in the figure), which can quickly connect to compressed air to provide power for backflushing. The valve disc 403 of the pneumatic valve assembly 4 is made of wear-resistant rubber, and each pipe is made of corrosion-resistant stainless steel, which can withstand long-term erosion by leachate. The backflushing process is automatically controlled by the system.

[0025] It should be noted that during normal suction, the valve discs 403 of the two pneumatic valve assemblies 4 are open, and the leachate enters the leachate flow pipe 1 through the connector 2, and is then sucked into the vacuum system through the leachate suction pipe 3 to achieve rapid delivery. When the system alarm is triggered by a blockage in the front connector 2 or the flow pipe 1, the system controls the pneumatic valve assembly 4 on the leachate suction pipe 3 and the sealing pipe 6 to close, and at the same time starts the air supply system of the vacuum suction system, opens the backflush valve 5, and compressed air is injected axially along the flow pipe through the backflush pipe 7 to blow out the blockage in reverse, preventing the blockage from spreading to subsequent pipelines. After the purging is completed, the pneumatic valve assembly 4 reopens and normal suction is restored. The entire process does not require manual disassembly and cleaning, which greatly improves the stability of system operation.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
