Description

A regenerative filtration device and its implementation method for reducing liquid waste emissions from construction. Technical Field

[0001] This invention belongs to the field of construction waste liquid treatment technology, specifically relating to a regenerative filtration device and implementation method for reducing construction waste liquid emissions. Background Technology

[0002] Construction waste liquids refer to wastewater generated during the construction process, which may contain various waste substances, such as residues of building materials, washed concrete, asphalt, or other building material residues. The solid particles, chemicals, or organic components contained in these waste liquids may have negative environmental impacts.

[0003] To reduce the negative environmental impact of these waste liquids, a regenerative filtration device and implementation method for reducing construction waste liquid emissions are needed to effectively separate and treat solid waste, organic components and other pollutants in the waste liquid to meet environmental protection standards, so as to minimize the environmental impact when it is reused or discharged into the environment, in order to comply with environmental regulations and reduce adverse environmental impacts.

[0004] However, existing equipment typically focuses on optimizing filtration devices to reduce clogging risk and improve treatment efficiency. These improvements usually include increasing filter surface area, modifying filter media, or designing more efficient filtration systems. However, most of these improvements concentrate on the physical filtration level and fail to adequately treat the organic components in the waste liquid, resulting in the equipment's inability to effectively decompose and treat organic waste in the waste liquid. Therefore, even after passing through the filtration system, the treated liquid still retains organic components, making it difficult to meet environmental emission standards. Summary of the Invention

[0005] The purpose of this invention is to provide a regenerative filtration device and implementation method for reducing waste liquid emissions from construction, which can effectively decompose and degrade organic materials, making the liquid more compliant with environmental emission standards.

[0006] The specific technical solution adopted by this invention is as follows:

[0007] A regenerative filtration device for reducing construction waste liquid emissions includes a storage tank and a construction waste liquid treatment mechanism installed on the storage tank. The construction waste liquid treatment mechanism includes a partition plate installed at the middle of the inner side of the storage tank, which divides the inner side of the storage tank into a mixing chamber and a filtering chamber. A support plate is fixed to the inner side of the mixing chamber, and a filter plate is installed to the inner side of the filtering chamber. A pump body is also installed inside the storage tank and at the bottom of the support plate. The input end of the pump body is connected to the mixing chamber, and the output end of the pump body is fixed to a delivery pipe connected to the filtering chamber. A drain pipe connected to the filtering chamber and a pressure plate connected to the mixing chamber are installed on the storage tank.

[0008] Furthermore, the construction waste liquid treatment mechanism also includes a pretreatment component installed above the storage tank. The pretreatment component includes a pretreatment box installed on the top of the storage tank. A baffle is fixed at the middle of the inner side of the pretreatment box. A sieve plate is installed at one end of the inner side of the pretreatment box, and the baffle is located below one end of the sieve plate. The end of the sieve plate away from the baffle is inclined towards the end closer to the baffle. The pretreatment box is connected to the mixing chamber on the storage tank through a guide pipe, and the guide pipe is located below the sieve plate.

[0009] Furthermore, the pretreatment assembly also includes an L-shaped mounting bracket, which is installed on the outer side of the pretreatment box away from the sieve plate. An electric push rod is installed at the top of the L-shaped mounting bracket, and a pressure plate is installed at the output end of the electric push rod. Multiple blades are installed at the bottom of the pressure plate.

[0010] Furthermore, a drive motor is installed at the bottom of the support plate, and a stirring rod is installed at the output end of the drive motor. The stirring rod is located inside the mixing chamber, and a heating rod is installed on the liquid storage tank inside the mixing chamber.

[0011] Another technical solution adopted by the present invention is as follows: A method for implementing a regeneration filtration device for reducing waste liquid emissions from construction projects includes the following steps:

[0012] S1: When construction waste liquid needs to be filtered, the liquid is directed to the upper part of the screen plate inside the pretreatment tank for pre-filtration. Large wastes such as construction mud, waste concrete blocks, and waste bricks and tiles are separated from the liquid. The impurities flow along the inclined direction of the screen plate to one end of the pretreatment tank for storage, while the liquid is guided to the mixing chamber on the upper part of the storage tank through the guide pipe.

[0013] S2: If the construction waste liquid contains organic components of waste mortar and waste asphalt mixture, a specific chemical reaction or solvent treatment is injected into the mixing chamber of the storage tank through the pressure plate, so that the liquid and solvent are mixed, decomposed and degraded, and then the T-shaped guide rod is activated to guide the liquid in the mixing chamber of the storage tank to the filter chamber on the storage tank.

[0014] S3: Liquid waste is filtered and separated through filter plates in the filter chamber to further remove chemicals and organic matter, thereby improving the purity and reusability of the treated liquid.

[0015] The technical effects achieved by this invention are as follows:

[0016] This invention, by pre-separating construction waste liquids, effectively reduces interference with liquid treatment and creates better conditions for subsequent processing. Secondly, when treating organic components in the waste liquid, the use of solvent mixing combined with precise heating and thorough mixing enables more complete degradation of these organic components. This significantly improves the purity and quality of the liquid, effectively decomposing and degrading organic materials. It not only improves the efficiency of liquid treatment but also greatly reduces the negative environmental impact through the active degradation of organic components. Attached Figure Description

[0023] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0024] As shown in Figures 1-4, a regenerative filtration device for reducing construction waste liquid emissions includes a storage tank 20 and a construction waste liquid treatment mechanism installed thereon. The construction waste liquid treatment mechanism includes a partition plate 12 installed at the middle position of the inner side of the storage tank 20, and the inner side of the storage tank 20 is divided into a mixing chamber and a filtering chamber by the partition plate 12. A support plate 14 is fixed on one side of the partition plate 12 and on the inner side of the mixing chamber on the storage tank 20. A filter plate 13 is installed on the side of the partition plate 12 away from the support plate 14 and on the inner side of the filtering chamber on the storage tank 20.

[0025] Referring to Figure 4, a pump body 16 is also installed inside the liquid storage tank 20 and at the bottom of the support plate 14. The input end of the pump body 16 is connected to the mixing chamber on the liquid storage tank 20. The output end of the pump body 16 is fixed with a delivery pipe 17, which is connected to the filter chamber. A drain pipe 21 connected to the filter chamber and a pressure plate 10 connected to the mixing chamber are installed on the liquid storage tank 20.

[0026] Referring to Figures 1-3, the construction waste liquid treatment mechanism also includes a pretreatment component installed above the storage tank 20. The pretreatment component includes a pretreatment box 1 installed on the top of the storage tank 20 via a support frame. A baffle 2 is fixed at the middle of the inner side of the pretreatment box 1. A sieve plate 3 is installed at one end of the inner side of the pretreatment box 1, and the baffle 2 is located below one end of the sieve plate 3. At the same time, the end of the sieve plate 3 away from the baffle 2 is tilted towards the end close to the baffle 2. The pretreatment box 1 is connected to the mixing chamber on the storage tank 20 via a guide pipe 9, and the guide pipe 9 is located below the sieve plate 3.

[0027] Based on the above structure, the specific implementation method is as follows:

[0028] Step 1: When construction waste liquid needs to be filtered, the liquid is directed to the area above the sieve plate 3 inside the pretreatment tank 1 for pre-filtration, separating large pieces of waste such as construction mud, waste concrete blocks, and waste bricks and tiles. These impurities flow along the inclined direction of the sieve plate 3 to one end of the pretreatment tank 1 for storage, while the liquid is guided through the guide pipe 9 to the mixing chamber on the upper part of the storage tank 20.

[0029] Step 2: If the construction waste liquid contains organic components such as waste mortar and waste asphalt mixture, a specific chemical reaction or solvent treatment can be injected into the mixing chamber of the storage tank 20 through the pressure plate 10. This treatment mixes the liquid with the solvent, decomposing and degrading the organic materials. Finally, the T-shaped guide rod 6 is activated to guide the liquid in the mixing chamber of the storage tank 20 to the filter chamber on the storage tank 20.

[0030] Step 3: Liquid waste is filtered and separated through filter plates 13 in the filtration chamber, further removing chemicals and organic matter to improve the purity and reusability of the treated liquid. This process ensures that the treated waste liquid meets specific environmental protection and reuse standards, achieving efficient decomposition and degradation of impurities and organic components in the waste liquid, making it meet environmental requirements and increasing its reuse value.

[0031] Referring to Figures 2 and 3, in addition, to facilitate the subsequent processing of large pieces of waste such as construction waste mud, waste concrete blocks, waste bricks and tiles, the pretreatment component also includes an L-shaped mounting frame 8. The L-shaped mounting frame 8 is installed on the outer side of the pretreatment box 1 away from the screen plate 3. An electric push rod 22 is installed at the top of the L-shaped mounting frame 8, and a pressure plate 10 is installed at the output end of the electric push rod 22. Multiple blades are installed at the bottom of the pressure plate 10.

[0032] According to the above structure, the operation of the electric push rod 22 drives the pressure plate 10 to move toward the impurities, thereby enabling multiple blades to crush and pulverize the impurities into smaller particles for subsequent processing and separation.

[0033] Referring to Figure 4, and in order to further enhance the effect of treating construction waste liquid, a drive motor 15 is installed at the bottom of the support plate 14, and a stirring rod 18 is installed at the output end of the drive motor 15. The stirring rod 18 is located inside the mixing chamber on the liquid storage tank 20. At the same time, a heating rod 19 is also installed on the liquid storage tank 20 and inside the mixing chamber.

[0034] According to the above structure, the operation of the drive motor 15 causes the stirring rod 18 to rotate, achieving full mixing of liquid and solvent, which helps to stimulate chemical reactions or solvent treatment, thereby accelerating the decomposition and degradation of organic components.

[0035] The heating rod 19 allows for precise heating of liquids and solvents, which helps optimize reaction temperatures, improves the efficiency of chemical reactions, and plays a key role in the degradation of organic matter.

[0036] The introduction of enhanced processing capacity not only simplifies the mixing and heating process but also provides greater processing power. This helps to further promote chemical reactions in the waste liquid, accelerating its decomposition and degradation, thereby improving the efficiency and thoroughness of waste liquid treatment.

[0037] Referring to Figure 3, in order to ensure the continuity and stability of waste liquid treatment, a vibration assembly is installed between the screen plate 3 and the pretreatment box 1. The vibration assembly includes L-shaped plates 4 fixed on both sides of the screen plate 3, T-shaped guide rods 6 fixed on both sides of the top of the pretreatment box 1, and the T-shaped guide rods 6 are movably connected to the L-shaped plates 4. A spring 7 is provided on the outside of the L-shaped plates 4 and between the L-shaped plates 4 and the pretreatment box 1. At the same time, a vibration motor 5 is installed on the top of the L-shaped plates 4.

[0038] According to the above structure, the operation of the vibration motor 5 can make the screen plate 3 vibrate through the L-shaped plate 4, which helps to reduce the adhesion of large pieces of waste such as construction mud, waste concrete blocks, waste bricks and tiles to the surface of the screen plate 3, reduce the probability of screen plate 3 clogging and impurity accumulation, help maintain the smooth operation of the device, reduce the processing interruption caused by impurity clogging or accumulation, and help improve the continuity and stability of waste liquid treatment.

[0039] Referring to Figures 1 and 3, and in order to facilitate the discharge of impurities, the end of the pretreatment box 1 away from the screen plate 3 is set as an opening, and a blocking plate 11 is inserted into the opening of the pretreatment box 1. When it is necessary to discharge impurities, the blocking plate 11 is pulled to release the blocking plate 11 from the opening of the pretreatment box 1, so that the impurities can be discharged conveniently.

[0040] In addition, sealing gaskets are installed on the outer side of the blocking plate 11 and the outer side of the sieve plate 3, which can reduce the amount of impurities flowing out from the gap between the blocking plate 11 and the pretreatment box 1 and between the sieve plate 3 and the pretreatment box 1, thereby improving the sealing performance of the device.

[0041] Meanwhile, a control host is also installed on the liquid storage tank 20, which is a mature existing technology. The vibration motor 5, the guide pipe 9, the support plate 14, the drive motor 15, and the electric valve of the pump body 16 are all connected to the control host. The control host automatically controls multiple electrical components, simplifying the operation process.

[0042] This invention, by pre-separating construction waste liquids, effectively reduces interference with liquid treatment and creates better conditions for subsequent processing. Secondly, when treating organic components in the waste liquid, the use of solvent mixing combined with precise heating and thorough mixing enables more complete degradation of these organic components. This significantly improves the purity and quality of the liquid, effectively decomposing and degrading organic materials. It not only improves the efficiency of liquid treatment but also greatly reduces the negative environmental impact through the active degradation of organic components.

[0043] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
