Description

Technical Field

[0001] The utility model belongs to the technical field of industrial water treatment pipelines, and in particular relates to an industrial water pretreatment pipeline with reduced costs. Background Art

[0002] The modular design of the disc filter allows for various combinations of filter units to meet the specific needs of different applications. The simple backwash controller provides comprehensive control of the filter or workstation based on pressure differential, time, or a combination of both. The disc filter element never needs replacement, with a lifespan of up to 15 years. Disc filters are widely used in developed countries, where their precise and stable operation under extremely demanding conditions and minimal maintenance have led to their widespread adoption in irrigation, wastewater treatment, sewage regeneration, municipal water supply, waterworks, large power plants, chemical plants, and emergency filtration.

[0003] Most of the pretreatment units for wastewater treatment in steel plants use a treatment process consisting of a high-efficiency sedimentation tank, a V-type filter, and a multi-media filter. The multi-media filter body is made of carbon steel, and the filter media are mostly quartz sand, anthracite, etc. The multi-media filter has many supporting valves, occupies a large area, and has a high construction cost.

[0004] The existing technology has the following shortcomings in use:

[0005] 1. The filter media of the multi-media filter is composed of quartz sand and activated carbon. When the backwash intensity is too high, the filter media is easily broken, the particle size becomes smaller, and the particles are discharged through the filter screen, resulting in poor filtering effect and increased turbidity.

[0006] 2. The multi-media filter is a round tank with a diameter of 3200mm. It has a small filtration flow rate, a large number of monomers, and occupies a large area.

[0007] 3. The backwash frequency of multi-media filters is high and the backwash time is long, resulting in waste of water resources.

[0008] Therefore, a cost-reducing industrial water pretreatment pipeline is proposed. Utility Model Content

[0023] In order to more clearly illustrate the technical scheme of the embodiments of the utility model, the following will briefly introduce the drawings needed to be used in the embodiment description. Obviously, the drawings in the following description are some embodiments of the utility model, and other drawings can be obtained by those skilled in the art without creative labor.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figure 1 As shown, a cost-reducing industrial water pretreatment pipeline includes a water production main 1, which is responsible for transporting treated water to subsequent use links, such as irrigation, production water, etc. By designing a reasonable pipe diameter and layout, the water flow resistance can be reduced and the water transportation efficiency can be improved.

[0026] The main water pipe 1 is connected to a filter water pipe 2. This ensures efficient water transfer and allows for flexible layout, facilitating on-site installation and maintenance. It leverages the high-efficiency filtration capabilities of the stacked filter to ensure high-quality effluent. This pipe is connected to an inlet pipe 4 via a connecting pipe 3, which draws in untreated water. Its efficient connection to other components ensures smooth water flow and effectively pre-treats the water.

[0027] Connecting pipe 3 is equipped with a filter element 5 and a three-way valve 6. The filter element 5 is responsible for removing suspended matter and impurities from the water, effectively filtering and ensuring the filtration effect. The three-way valve 6 is used to adjust the direction of the water flow, which can control the on-off flow of the water and the process of sewage discharge. The three-way valve 6 leads to a sewage pipe 7, which is responsible for discharging the filtered sewage. The sewage pipe 7 is connected to a drainage ditch 8, which is used to discharge the removed sewage to ensure normal operation. At the same time, the external discharge must comply with environmental protection standards to reduce the impact on the natural environment.

[0028] The following is a detailed description of the design of the above key components:

[0029] The three-way valve 6 is an electric regulating valve. This valve can adjust the direction of water flow in real time through an electronic control system, automatically switching according to demand to adapt to different operating conditions. Preferably, the valve can be interlocked with flow sensors, pressure sensors, and other sensors to provide more accurate flow and pressure monitoring. The valve is powered by 24V DC or 110V / 220VAC. In the event of a power outage or failure, the valve returns to its default state.

[0030] The inner wall of the sewage pipe 7 is provided with an anti-corrosion coating. The material of the anti-corrosion coating can be epoxy resin, polyurethane or other anti-corrosion coatings. It can be used to deal with various chemical components in sewage and reduce the impact of corrosion on the sewage pipe 7. The anti-corrosion coating is applied by spraying or brushing to ensure uniformity and adhesion of the coating. Surface treatment is also required to improve the adhesion quality of the coating.

[0031] The filter element 5 is replaceable. The filter element 5 is made of high-performance materials such as polypropylene, polyester or stainless steel mesh to improve filtration efficiency and durability. The filter element 5 is designed in a modular form that is easy to disassemble and assemble, making it easy for maintenance personnel to replace it while ensuring sealing with the pipeline.

[0032] The filter water production pipe 2 is L-shaped and is connected to the water production main pipe 1. The L-shaped filter water production pipe 2 effectively utilizes space and is convenient for flexible layout in a limited space.

[0033] A pressure sensor is installed in the connecting tube 3. Select a high-precision, fast-response pressure sensor, such as a resistance strain gauge pressure sensor. The pressure sensor should be located in the middle of the connecting tube 3 to ensure accurate measurement. It should be designed to be vibration- and corrosion-resistant, enabling stable operation under high pressure and harsh environments. The pressure sensor supports analog output (such as 0-10V or 4-20mA) or digital signal output, facilitating connection to a host computer or PLC for data monitoring and control.

[0034] The number of connecting pipes 3 connecting the filter's water production pipe 2 and water inlet pipe 4 is set accordingly. The number of filter elements 5 and three-way valves 6 corresponds to the number of connecting pipes 3, and the number of sewage pipes 7 corresponds to the number of three-way valves 6. The number of connecting pipes 3 should be designed based on the system's flow requirements and layout space to ensure that each connecting pipe 3 can effectively carry the required flow. Based on actual conditions, the distribution of connecting pipes 3 should be reasonably arranged to ensure a stable and leak-free connection with the filter's water production pipe 2 and water inlet pipe 4. Each connecting pipe 3 can be quickly installed and replaced, thereby reducing operational complexity and increasing convenience and practicality.

[0035] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
