Description

Technical Field

[0001] This utility model relates to the field of inorganic anti-corrosion coating production technology, and in particular to a wastewater recycling treatment device for inorganic anti-corrosion coating production. Background Technology

[0002] In the field of inorganic anti-corrosion coating production, wastewater treatment is a crucial link in ensuring production sustainability and environmental friendliness. With increasingly stringent environmental protection requirements, efficient and environmentally friendly recycling of wastewater from inorganic anti-corrosion coating production has become an important research direction in the industry.

[0003] A search revealed Chinese patent CN208814756U, which discloses an energy-saving and environmentally friendly wastewater recycling device for paint production. The device comprises a paint production unit, an observation and monitoring platform, a circulating water pump, a ladder, an operation control cabinet, and a wastewater purification and recycling device. The right end of the paint production unit is connected to the wastewater purification and recycling device, and the observation and monitoring platform is mounted on the outer surface of the paint production unit and connected by welding. This patent fully utilizes the gravitational potential energy generated when wastewater enters the treatment equipment, using it as the driving force for wastewater purification. This significantly saves energy and ensures thorough mixing of the wastewater and the treatment liquid, resulting in uniform mixing. Simultaneously, continuous aeration of the wastewater and stirring allow for full contact and reaction between the gas and wastewater, further dissolving microorganisms and impurities in the wastewater. Furthermore, it promptly removes sediment and sludge, preventing corrosion and oxidation of the equipment and extending its service life.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Existing wastewater recycling equipment for inorganic anti-corrosion coating production generally suffers from fragmented functions and low levels of automation. Many systems separate wastewater filtration, sedimentation, and advanced treatment processes into different devices, requiring frequent manual wastewater transfers. This not only consumes significant manpower and time but also increases the risk of spillage, leading to low treatment efficiency and secondary pollution risks. Furthermore, some systems rely on manual operation for impurity cleaning, requiring operators to directly contact wastewater and impurities, increasing health and safety hazards. This is because existing equipment lacks integrated design and automated control mechanisms, failing to effectively integrate the various wastewater treatment processes and automate operations such as impurity cleaning, thus failing to meet the demands for efficient and environmentally friendly wastewater treatment. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a wastewater recycling treatment device for inorganic anti-corrosion coating production. By setting a gate mechanism in the container body to divide the pretreatment, reaction treatment and deep treatment areas, and cooperating with a parallel track mechanism, filter screen mechanism, water tank device and drive mechanism, the wastewater can be processed in an orderly manner from high-pressure jet filtration and automated impurity removal to coagulation sedimentation and deep treatment.

[0007] The technical solution to achieve the purpose of this utility model is: a wastewater recycling treatment device for inorganic anti-corrosion coating production, including a container body, wherein the container body is provided with two sets of gate mechanisms, which divide the area into three zones: a pretreatment zone, a reaction treatment zone, and a deep treatment zone, and further includes:

[0008] The parallel track mechanism includes two sets of track frames disposed on the inner wall of the pretreatment area. The upper end of each set of track frames extends outward to the outer side of the container body, forming a U-shaped structure that fits between the outer side of the container body and the inner side of the pretreatment area.

[0009] The filter screen mechanism is movably arranged between two sets of parallel track mechanisms. The filter screen mechanism includes a screen box body with a hollow top. Guide rods that pass through the two sets of track frames are arranged through the screen box body. The two guide rods extend outward at both ends, and the free ends of the two guide rods are connected to connecting blocks.

[0010] A water tank device, wherein the water tank device is located at the other end of the outer side of the container body;

[0011] The drive mechanism is located outside the two sets of parallel track mechanisms. The drive mechanism controls the filter screen mechanism to reciprocate and adjust the pretreatment area and the outside of the container body along the two sets of parallel track mechanisms.

[0012] A mobile collection vehicle is located below the flip side of the screen box body to receive impurities after rinsing.

[0013] In some embodiments, the drive mechanism includes a pneumatic controller disposed outside the container body and a pneumatic robotic arm connected to the output end of the pneumatic controller. The output end of the pneumatic robotic arm extends upward along the outer side of the container body and into the pre-treatment area. The output end extending into the pre-treatment area is fixedly connected to a corresponding connecting block.

[0014] In some embodiments, the output end of the water tank device flows from the top of the container body to the filter screen mechanism. The water tank device includes a water tank body and an inlet pipe for water inlet outside the water tank body. An arc-shaped nozzle is provided on the top of the water tank body. The bottom of the nozzle is installed on the top of the water tank body through a support plate. A high-pressure water pump is provided on the outside of the water tank body. The high-pressure water pump is connected to the water tank body and the nozzle through a pipe.

[0015] In some embodiments, the mobile collection vehicle includes a collection vehicle body located outside the container body, and the bottom of the collection vehicle body is provided with casters.

[0016] In some embodiments, the pretreatment area is located at the front end of the container body for preliminary filtration of wastewater;

[0018] The deep processing zone is connected to the interior of the reaction processing zone through a second set of gate mechanisms, and a drainage pipe connecting to the rear exterior of the container body is installed at its end.

[0019] In some embodiments, the gate mechanism includes a limiting frame installed inside the container body. The limiting frame is a U-shaped frame, and a gate plate is slidably disposed in the internal groove of the limiting frame. A cylinder is provided at the top of each limiting frame, and the bottom output end of the cylinder is connected to the top of the corresponding gate plate. The gate plate is used to control the gate plate to move up and down inside the limiting frame.

[0020] In some embodiments, the tops of the reaction processing zone and the deep processing zone are sealed by baffles, and a feed hopper for feeding is installed on the top baffle of the reaction processing zone.

[0021] Compared with existing technologies, the significant advantages of this invention are:

[0022] Firstly, this utility model utilizes two sets of gate mechanisms within the container to divide the pretreatment area, reaction treatment area, and deep treatment area. Combined with a parallel track mechanism, filter screen mechanism, water tank device, and drive mechanism, it achieves an automated process where external production wastewater is sprayed from the water tank body through a high-pressure water pump and nozzles to the screen box body for filtration. The drive mechanism then controls the screen box body to rotate along the track frame to remove impurities. This integrated and automated structural design, compared to existing wastewater treatment equipment with fragmented functions and frequent manual operation, reduces human intervention in the wastewater treatment process, lowers the risk of pollution from operator contact with wastewater, and ensures close connection between each treatment stage, avoiding wastewater loss during transfer and significantly improving the efficiency and quality of wastewater treatment.

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0032] This utility model provides an improved wastewater recycling treatment device for inorganic anti-corrosion coating production. The technical solution of this utility model is as follows:

[0033] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0034] like Figures 1-4 As shown, an inorganic anti-corrosion coating production wastewater recycling treatment equipment includes a container body 100. The container body 100 is equipped with two sets of gate mechanisms, which divide the container into three areas: a pretreatment area 101, a reaction treatment area 102, and a deep treatment area 103. The equipment also includes a parallel track mechanism, a filter screen mechanism, a water tank device, and a drive mechanism. The parallel track mechanism includes two sets of track frames 601 disposed on the inner wall of the pretreatment area 101. The upper end of each set of track frames 601 extends outward to the outer side of the container body 100, forming a U-shaped structure that fits between the outer side of the container body 100 and the inner side of the pretreatment area 101. A filter screen mechanism is movably disposed between the two sets of parallel track mechanisms. The filter screen mechanism includes a screen box body 500 with a hollow top. A guide rod 501 is disposed through the screen box body 500 and passes through the two sets of track frames 601. The two guide rods 501 extend outward at both ends, and the free ends of the two guide rods 501 are connected to a connecting block 502. A water tank device is disposed at the other end of the outer side of the container body 100, and the output end of the water tank device flows from the top of the container body 100 to the filter screen mechanism. A drive mechanism is disposed outside the two sets of parallel track mechanisms. The drive mechanism controls the filter screen mechanism to reciprocate and rotate back and forth between the pretreatment area 101 and the outer side of the container body 100 along the two sets of parallel track mechanisms. This integrated design changes the situation where the functions of wastewater treatment equipment are scattered in the existing technology. It integrates multiple stages of wastewater treatment into the container body, reducing the equipment's footprint. At the same time, the orderly structural layout makes the wastewater treatment process smoother.

[0035] like Figure 3 As shown, in one embodiment, the pretreatment zone 101 is located at the front end of the container body 100 and is used for preliminary wastewater filtration; the reaction treatment zone 102 is connected to the pretreatment zone 101 via a first set of gate mechanisms and is used for coagulation and sedimentation; the deep treatment zone 103 is connected to the reaction treatment zone 102 via a second set of gate mechanisms, and its end is provided with a drain pipe 104 connecting to the rear exterior of the container body 100. The three zones work together to achieve a complete wastewater treatment process from preliminary filtration and coagulation / sedimentation to deep treatment. Compared to the dispersed treatment processes and frequent wastewater transfers in existing technologies, this equipment reduces wastewater loss and the risk of secondary pollution during treatment, significantly improving wastewater treatment efficiency and quality.

[0036] like Figure 1 , Figure 2 as well as Figure 4 As shown, in one embodiment, the drive mechanism includes a pneumatic controller 602 disposed outside the container body 100 and a pneumatic robotic arm 600 connected to the output end of the pneumatic controller 602. The output end of the pneumatic robotic arm 600 extends upward along the outer side of the container body 100 and into the pretreatment area 101. The output end extending into the pretreatment area 101 is fixedly connected to a corresponding connecting block 502. The drive mechanism controls the connecting block 502 to drive the guide rod 501 to extend and retract within the track frame 601, thereby transporting the screen box body 500 back and forth between the pretreatment area 101 and the outside of the container body 100. When the screen box body 500 intercepts a large amount of impurities, the drive mechanism can automatically flip it outward to the outside of the container body 100 for cleaning, eliminating the need for manual cleaning, reducing the risk of pollution caused by manual contact with wastewater, and improving the automation level of equipment operation.

[0037] like Figures 1-4 As shown, in one embodiment, the water tank device includes a water tank body 200 and an inlet pipe 201 for external water intake. An arc-shaped nozzle 204 is provided on the top of the water tank body 200. The bottom of the nozzle 204 is mounted on the top of the water tank body 200 via a support plate. A high-pressure water pump 202 is provided on the outside of the water tank body 200, and the high-pressure water pump 202 connects the water tank body 200 and the nozzle 204 via a pipe. External production wastewater flows into the high-pressure water pump 202 through the inlet pipe 201. The high-pressure water pump 202 then transports the wastewater from inside the water tank body 200 to the connector 203 through the water pipe. The wastewater then flows from the connector 203 into the nozzle 204, and finally is sprayed from the arc-shaped opening at the top of the nozzle 204 into the filter screen mechanism inside the pretreatment area 101. The high-pressure jet method allows the wastewater to be distributed more evenly within the screen box body 500, improving filtration efficiency. At the same time, the impact force of the water flow helps to better intercept impurities within the screen box body 500, enhancing the initial filtration effect.

[0038] like Figure 2 As shown, in one embodiment, the mobile collection vehicle includes a collection vehicle body 800 located outside the container body 100, and the bottom of the collection vehicle body 800 is provided with casters 801. This mobile collection vehicle can not only collect the impurities filtered inside the pretreatment area 101 as they fall outside with the screen box body 500, but also the casters 801 at the bottom of the collection vehicle body 800 can move and carry away the collected impurities, facilitating the collection and transportation of impurities and solving the problem of inconvenient impurity collection in existing wastewater treatment equipment.

[0039] like Figures 1-3 As shown, in one embodiment, the gate device includes a limiting frame 400 installed inside the container body 100. The limiting frame 400 is a U-shaped frame, and a gate plate 401 is slidably disposed in the internal groove of the limiting frame 400. Each limiting frame 400 has a cylinder 402 at its top, and the bottom output end of the cylinder 402 is connected to the top of the corresponding gate plate 401. The gate plate 401 is used to control the raising and lowering of the gate plate 401 inside the limiting frame 400. By controlling the raising and lowering of the gate plate 401 by the cylinder 402, the channels between each treatment area can be precisely opened or closed, ensuring that wastewater is treated in an orderly manner according to the process, avoiding the chaotic water flow control situation in the prior art.

[0040] In one embodiment, the tops of the reaction processing zone 102 and the deep processing zone 103 are sealed by baffles, and a feed hopper 900 is installed on the top baffle of the reaction processing zone 102. Added materials can flow into the reaction processing zone 102 from the feed hopper 900 to disinfect the filtered production wastewater inside the pretreatment zone 101. The top-sealed design and the feed hopper 900 ensure that the reagent addition is carried out in a closed environment, preventing reagent leakage and pollution, and solving the problem of environmental pollution caused by reagent addition in existing equipment.

[0041] The working principle and usage process of this utility model are as follows: First, the wastewater from the production of external inorganic anti-corrosion coatings enters the water tank body 200 through the inlet pipe 201. The high-pressure water pump 202 is started, pressurizing the wastewater in the water tank body 200 and then conveying it to the arc-shaped nozzle 204 through the connector 203. The wastewater enters the screen box body 500 in the pretreatment area 101 through the high-pressure jet from the top opening of the nozzle 204. The screen box body 500 performs preliminary filtration of the wastewater, intercepting larger particulate impurities. When there are many impurities in the screen box body 500 and cleaning is required, the pneumatic controller 602 controls the pneumatic robotic arm 600. The pneumatic robotic arm 600 drives the connecting block 502 and the guide rod 501, causing the screen box body 500 to move along the track frame 601 towards the outside of the container body 100. The screen box body 500 is then flipped over, and the impurities fall into the collection cart body 800 below. The universal wheels 801 at the bottom of the collection cart body 800 facilitate its movement and remove the impurities. After cleaning, the pneumatic robotic arm 600 brings the screen box body 500 back to the pretreatment area 101 to continue working. The pre-filtered wastewater remains in the pretreatment area 101. At this time, the cylinder 402 in the first gate mechanism drives the gate plate 401 to rise, opening the channel between the pretreatment area 101 and the reaction treatment area 102, allowing the wastewater to flow into the reaction treatment area 102. Coagulation and sedimentation agents are added to the reaction treatment area 102 through the feed hopper 900 to perform coagulation and sedimentation treatment on the wastewater. After treatment, the cylinder 402 drives the gate plate 401 to fall, closing the channel between the pretreatment area 101 and the reaction treatment area 102. Next, the cylinder 402 in the second gate mechanism drives the gate plate 401 to rise, opening the channel between the reaction treatment area 102 and the deep treatment area 103, allowing the coagulated and sedimentated wastewater to flow into the deep treatment area 103 for further treatment. After deep treatment, the purified water is discharged from the container body 100 through drain pipe 104, and can be recycled or discharged, completing the entire recycling process for the wastewater from the inorganic anti-corrosion coating production. Throughout the process, all structures work together to achieve efficient, orderly, and environmentally friendly wastewater treatment, overcoming many shortcomings of existing technologies.

Matters not covered in this utility model are common knowledge to those skilled in the art.
