Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically, to a modular anti-corrosion integrated structure for integrated sewage treatment equipment. Background Technology

[0002] Integrated wastewater treatment equipment is widely used in the treatment of municipal sewage, industrial wastewater and rural domestic sewage due to its advantages such as small footprint, high treatment efficiency and convenient installation. The equipment usually contains multiple functional units such as screens, sedimentation tanks, biological reaction tanks and filtration tanks. These units are in long-term contact with sewage containing acids, alkalis, salts, organic matter and microorganisms, which are prone to corrosion, affecting the service life and treatment effect of the equipment.

[0003] Currently, corrosion protection for integrated wastewater treatment equipment mostly involves applying anti-corrosion coatings or lining with anti-corrosion layers. However, this approach has several drawbacks: First, the overall anti-corrosion structure struggles to adapt to the varying corrosive environments of different functional units. For instance, the microbial corrosion in biological reactors differs from the chemical corrosion in sedimentation tanks, leading to different requirements for anti-corrosion materials. A uniform anti-corrosion treatment can easily result in localized failures. Second, traditional equipment often features fixed connections between functional units. When a localized anti-corrosion layer is damaged, the entire equipment must be repaired or replaced, resulting in high maintenance costs, long cycles, and disruption to continuous operation. Therefore, we propose a modular integrated anti-corrosion structure for integrated wastewater treatment equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a modular anti-corrosion integrated structure for integrated sewage treatment equipment to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Preferably, the lower corrosion-resistant pad, the upper corrosion-resistant pad, and the inner pressure-resistant fixing frame are integrally formed, and the inner pressure-resistant fixing frame has a radial structure.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4This utility model provides a technical solution: a modular anti-corrosion integrated structure for an integrated sewage treatment equipment, including an integrated sewage treatment machine body 1, which is composed of multiple interconnected treatment tanks 10. The multiple treatment tanks 10 can be connected by anti-corrosion flanges. Each corresponding treatment tank 10 has a corresponding functional treatment module installed inside. A first inner anti-corrosion layer 11 is fixedly installed on the inner wall of the treatment tank 10. For example, a grid module, sedimentation module, biological reaction module, and filtration module can be set inside the corresponding treatment tank 10. The first inner anti-corrosion layer 11 of the grid module and sedimentation module can be made of glass fiber reinforced plastic with a thickness of 8~12mm, which has good chemical corrosion resistance and can resist the erosion of acid and alkali substances in sewage. The first inner anti-corrosion layer 11 of the biological reaction module can be made of polytetrafluoroethylene lining with a thickness of 3~5mm, which can withstand the corrosion of organic acids produced by microbial metabolism and high temperature environment. The first inner anti-corrosion layer 11 of the filtration module is made of rubber lining with a Shore hardness of 60~70 degrees, which has excellent wear resistance and impact resistance and can adapt to particle friction during the filtration process.

[0031] A maintenance cylinder 2 is fixedly installed on the top of the treatment tank 10. A second inner anti-corrosion layer 20 is fixedly installed on the inner wall of the maintenance cylinder 2. The corresponding first inner anti-corrosion layer 11 and second inner anti-corrosion layer 20 are selected according to the nature of sewage treatment, so that different treatment units can adapt to their respective corrosive environments and improve the overall anti-corrosion targeting.

[0032] In this embodiment, a corrosion-resistant sealing gasket 23 is provided on the top of the inspection cylinder 2, which can perform a sealing operation; a corrosion-resistant sealing cover 24 is detachably installed on the top of the inspection cylinder 2, which presses the corrosion-resistant sealing gasket 23 tightly onto the top surface of the inspection cylinder 2, and the corrosion-resistant sealing cover 24 can further achieve a sealing effect.

[0033] like Figure 1 As shown, multiple fixed bases 12 are fixedly installed at the bottom of the treatment tank 10. The height of the fixed bases 12 is between 8cm and 12cm, which keeps the bottom of the treatment tank 10 away from ground moisture and corrosive media, reduces the risk of bottom corrosion, and enhances the stability of the equipment placement.

[0034] like Figure 1 As shown, a drain pipe 13 is fixedly installed on the bottom tank of the treatment tank 10, and a drain valve 14 is fixedly installed on the drain pipe 13. The residual sewage and impurities in the tank can be discharged in time during maintenance or cleaning to avoid long-term retention of pollutants and aggravation of corrosion, and to facilitate equipment maintenance.

[0035] Specifically, an inlet pipe 15 is fixedly installed on the top tank of the treatment tank 10, and an outlet pipe 16 is also fixedly installed on one side of the top tank of the treatment tank 10, which facilitates connection with external pipelines to form a complete treatment process, ensures that sewage flows through each functional module in sequence, and improves the integration and ease of operation of the equipment.

[0036] Furthermore, a fixing ring 21 is fixedly installed on the top cylinder of the inspection cylinder 2. The anti-corrosion sealing cover 24 is detachably connected to the fixing ring 21 by multiple fastening bolts, making it easy to disassemble and assemble the sealing cover, and facilitating the inspection and maintenance of the inside of the treatment tank 10 through the inspection cylinder 2, thus reducing the difficulty of maintenance.

[0037] In addition, the corrosion-resistant sealing gasket 23 is composed of a lower corrosion-resistant gasket 231 and an upper corrosion-resistant gasket 234 disposed above the lower corrosion-resistant gasket 231. An inner pressure-resistant fixing frame 232 is provided between the lower corrosion-resistant gasket 231 and the upper corrosion-resistant gasket 234. The lower corrosion-resistant gasket 231, the upper corrosion-resistant gasket 234 and the inner pressure-resistant fixing frame 232 are integrally formed structures. The inner pressure-resistant fixing frame 232 has a radial structure, which enhances the structural strength and pressure resistance of the sealing gasket and ensures stable sealing performance during long-term use.

[0038] It is worth noting that multiple positioning protrusions 22 are fixedly installed on the top surface of the fixing ring 21, and multiple positioning holes 233 are provided in the inner pressure-resistant fixing frame 232. The upper and lower ends of the positioning holes 233 are connected to the outside. The positioning protrusions 22 are located in the positioning holes 233 and are inserted and matched with the positioning holes 233 to achieve precise positioning of the corrosion-resistant sealing gasket 23, prevent the sealing gasket from being misaligned and affecting the sealing effect, and ensure reliable corrosion protection and sealing.

[0039] In use, the modular anti-corrosion integrated structure of the integrated sewage treatment equipment of this utility model places multiple treatment tanks 10 of the main body 1 of the integrated sewage treatment machine stably through the fixed base 12, connects the inlet pipe 15 and outlet pipe 16 of each treatment tank 10, and arranges the corresponding pipelines to form a complete sewage treatment pipeline; according to the nature of sewage, ensure that the first inner anti-corrosion layer 11 of the inner wall of each treatment tank 10 and the second inner anti-corrosion layer 20 of the inspection cylinder 2 are adapted to the corresponding corrosive environment.

[0040] Before starting the equipment, check the corrosion-resistant sealing gasket 23 on the top of the inspection cylinder 2 to ensure that the positioning protrusion 22 is inserted into the positioning hole 233. Fix the anti-corrosion sealing cover 24 to the fixing ring 21 with the fastening bolts, and press the sealing gasket to achieve a seal. The sewage enters the treatment tank 10 through the inlet pipe 15, and is discharged from the outlet pipe 16 after being treated by the internal functional treatment module.

[0041] When maintenance is required, remove the anti-corrosion sealing cover 24, check the internal condition through the inspection cylinder 2, open the drain valve 14 during cleaning to allow residual sewage to be discharged from the drain pipe 13, and after maintenance is completed, reinstall the corrosion-resistant sealing gasket 23 and the anti-corrosion sealing cover 24 to ensure reliable sealing before resuming operation.
