Description

Technical Field

[0001] This utility model relates to the field of turbid circulating water treatment equipment, and in particular to the turbid circulating water tank filter residue mechanism. Background Technology

[0002] In the metalworking industry, such as machinery manufacturing and automotive parts processing, large quantities of cutting fluid and coolant are used to cool and lubricate cutting tools and machined parts. During the circulation process, these fluids can mix with impurities such as metal shavings and abrasive particles, forming turbid circulating water. If these residues are not removed promptly, they can affect machining accuracy, accelerate tool wear, and potentially clog cooling pipes in the machining equipment.

[0003] When treating turbid circulating water, filter cake may accumulate unevenly at the bottom of the tank. Excessive localized accumulation can exert significant pressure on the tank's bottom structure. Over time, this uneven pressure can cause cracks and deformation at the bottom of the tank, shortening its lifespan, hindering the effective separation of solid particles, affecting water clarity, and making it difficult to remove residue in a timely manner. This increases treatment time and costs, and reduces the overall system efficiency. Furthermore, the lack of a sieving and cleaning mechanism during treatment allows filter cake to continuously accumulate on the filter screen or filter components. Over time, the pores of the filter screen become filled with a large amount of filter cake, causing a sharp increase in resistance to water flow, reducing treatment efficiency, and making it difficult to effectively remove suspended solids and impurities from the water.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its specially designed air flotation stirring mechanism, solves the problems of ineffective separation of solid particles, affecting water clarity, and causing sludge to be difficult to discharge in a timely manner, thus increasing processing time and cost and reducing the overall system efficiency. A belt connects the first rotating rod to the second support ring on the bottom second rotating rod, driving the second rotating rod and the second support ring to rotate. This ensures that the rotation of the first rotating rod drives the second rotating rod to rotate synchronously. A fixing ring is then used to fix the first and second rotating rods to their outer sides and connects to the stirring plates, allowing the first and second rotating rods to drive the stirring plates to rotate. The stirring plates on the upper and lower sides are arranged in a crisscross pattern, improving stirring efficiency and making the air flotation process more uniform, thereby effectively improving the removal efficiency of solid matter and reducing the suspended solids content in the water.

[0016] 2. By incorporating a sieve cylinder, a second motor, a rotating shaft, a collection tank, scrapers, a drain pipe, a fixed plate, and a pump, the system effectively addresses the problems of drastically increased resistance to water flow through the filter screen, decreased treatment efficiency, and difficulty in effectively removing suspended solids and impurities from the water. Turbid circulating water enters the sieve cylinder through the second connecting pipe and flows into the tank through the sieve cylinder's perforations. Impurities in the turbid circulating water adhere to the inner wall of the sieve cylinder. As the sieve cylinder rotates, it pulls these impurities along with it. Once a certain rotation is achieved, the scrapers on the top support plate of the collection tank remove the impurities, causing them to fall into the collection tank for collection. After collection, the impurities, along with some of the turbid circulating water, flow into the collection tank and are then discharged through the drain pipe, effectively reducing the burden on the water treatment equipment, minimizing wear, extending the equipment's lifespan, and reducing the frequency of maintenance and replacement.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] like Figure 1 - Figure 4 As shown: The turbidity circulation tank filter cake mechanism includes a box 1, and an air flotation stirring mechanism 2 is installed inside the box 1;

[0034] The air flotation mixing mechanism 2 includes: a connecting plate 201, a base plate 203, a first motor 207, and a second rotating rod 210. The right side wall of the connecting plate 201 is fixedly connected to the left side wall of the housing 1. An air tank 202 is fixedly connected to the left side wall of the connecting plate 201. The air tank 202 is fixed to the left side wall of the housing 1 by connecting the connecting plate 201 and the air tank 202. The right side wall of the base plate 203 is fixedly connected to the bottom of the left side wall of the housing 1. An air pump 204 is provided on the upper side wall of the base plate 203. A delivery pipe 205 is fixedly connected to the output end of the air pump 204. The top end of the delivery pipe 205 is connected to the front end of the air tank 202. The base plate 203 supports the top of the air pump 204, and the generated gas is transmitted through the delivery pipe 205 at the output end of the air pump 204. The gas is stored inside the air tank 202. The upper and lower sides of the air tank 202 are connected to the air outlet pipes 206. The right ends of the four air outlet pipes 206 are connected to the upper and lower sides of the left side wall of the box 1. The gas is blown evenly into the interior of the box 1 through the four air outlet pipes 206 on the upper and lower sides of the air tank 202 to fully contact the impurities and particles in the turbid circulating water. The gas is transferred into the interior of the box 1 and the bubbles generated cause the impurities and particles to float on the surface of the turbid circulating water. The first motor 207 is fixedly connected to the front side wall of the box 1. The output end of the first motor 207 is fixedly connected to the first rotating rod 208. The front and rear ends of the first rotating rod 208 are connected to the front and rear side walls of the box 1. The rear end of the first rotating rod 208 is fixedly connected to the outer side of the first supporting ring 209.

[0035] By fixing the first motor 207 to the front side wall of the housing 1, the first motor 207 can stably drive the first rotating rod 208 to rotate. A belt 212 is rotatably connected inside the first support ring 209. The front and rear ends of the second rotating rod 210 are rotatably connected to the front and rear side walls of the housing 1. A second support ring 211 is fixedly connected to the outer rear end of the second rotating rod 210, and the bottom of the second rotating rod 210 is rotatably connected to the outer side of the second support ring 211. When the first rotating rod 208 rotates, it drives the belt 212 to rotate through the first support ring 209 at the rear end. The belt 212 then connects to the second support ring 211 at the rear end of the second rotating rod 210, causing the second support ring 211 and the second rotating rod 210 to rotate inside the housing 1. The rotation of the first rotating rod 208 causes the second rotating rod 210 to rotate synchronously. Both the first and second rotating rods 208 and 210 are fixedly connected to the outer sides of a plurality of 213s, and stirring blades 214 are fixedly connected to the outer sides of each 213. The top and bottom stirring blades 214 are arranged in a cross configuration. The stirring blades 214 are rotated by the 213s on the first and second rotating rods 208 and 210, respectively. The cross configuration of the stirring blades 214 on both the upper and lower sides improves the stirring efficiency, makes the air flotation process more uniform, and ensures that the microbubbles generated by the air pump 204 can fully contact and combine with more suspended particles, thereby improving the efficiency of air flotation separation.

[0036] like Figure 1 - Figure 5 As shown, a control panel 3 is fixedly connected to the top of the front side wall of the housing 1. The control panel 3 is used to control and switch the entire device on and off. A first connecting pipe 4 is connected through the front side wall of the housing 1, which connects to external pipes to transfer turbid circulating water into the housing 1 for treatment. Drain holes 18 are connected through the front and rear sides of the right side of the housing 1 to discharge the treated turbid circulating water. A baffle 5 is fixedly connected inside the housing 1. The interior of the box 1 is divided into two areas to treat the turbid circulating water. A guide box 6 is connected through the interior of the baffle 5. The turbid circulating water and impurities driven by the top stirring plate 214 are pushed into the interior of the guide box 6 for guidance. A transfer groove 7 is fixedly connected to the bottom wall of the interior of the guide box 6. A second connecting pipe 8 is connected through the bottom wall of the transfer groove 7. The turbid circulating water entering the interior of the guide box 6 will be connected to the second connecting pipe 8 through the transfer groove 7 and transferred to the interior of the sieve cylinder 10 for treatment.

[0037] like Figure 1 - Figure 11As shown, a pipe support ring 9 is fixedly connected to the right end of the second connecting pipe 8. A sieve cylinder 10 is rotatably connected inside the right end of the pipe support ring 9. The sieve cylinder 10 filters the turbid circulating water and impurities. The turbid circulating water flows into the interior of the housing 1 through the holes and grooves of the sieve cylinder 10, while the impurities remain inside the sieve cylinder 10. A second motor 11 is installed on the right side wall of the housing 1, and a support column 13 is fixedly connected inside the right side wall of the housing 1. A rotating shaft 12 is fixedly connected to the output end of the second motor 11. The outer side of the rotating shaft 12 is rotatably connected to the inside of the support column 13. The left end of the rotating shaft 12 is fixedly connected to the right end of the sieve cylinder 10. The right end of the sieve cylinder 10 is rotatably connected to the left end of the support column 13. The rotating shaft 12 on the output end of the sieve cylinder 10 rotates inside the support column 13, and the support column 13 provides external protection for the rotating shaft 12. The rotating shaft 12 drives the right end of the sieve cylinder 10 to rotate on the left end of the support column 13, and the left end of the sieve cylinder 10... The tube support ring 9 rotates inside to support and fix the left and right ends of the sieve cylinder 10. A collection trough 14 is provided inside the sieve cylinder 10. A support plate 15 is fixedly connected to the top rear wall of the collection trough 14, and a scraper 16 is fixedly connected to the top of the support plate 15. When the sieve cylinder 10 rotates, it causes the impurities adhering to the inner wall to rotate as well. During rotation, the support plate 15 at the top of the collection trough 14 supports and fixes the scraper 16, and the scraper 16 scrapes away the impurities from the inner wall of the sieve cylinder 10. The impurities fall into the collection tank 14 for collection. The scraper 16 is correspondingly set to the inner wall of the sieve cylinder 10. A drain pipe 17 is connected through the left side wall of the collection tank 14. The bottom end of the drain pipe 17 passes through the bottom wall of the second connecting pipe 8 and is connected to the rear side wall of the box 1. Some turbid circulating water and external water flow into the collection tank 14 to mix with the impurities, thereby driving the impurities into the drain pipe 17 and discharging the impurities into the box 1 through the drain pipe 17.

[0038] like Figure 1 - Figure 12As shown, a fixing plate 19 is fixedly connected to the right side of the rear wall of the housing 1. A pump 20 is installed on the top of the fixing plate 19. The fixing plate 19 supports and fixes the bottom of the pump 20. An adapter pipe 21 is fixedly connected to the input end of the pump 20, and a transmission pipe 22 is fixedly connected to the output end of the pump 20. The other end of the transmission pipe 22 is connected to a spray pipe 24. The adapter pipe 21 on the input end of the pump 20 is used to connect to external pipes, water tanks, etc., to draw water from the outside. The water is then transferred to the spray pipe 24 through the transmission pipe 22 on the output end of the pump 20. Fixing rings 23 are fixedly connected to both ends of the spray pipe 24. All three are fixedly connected to the right side wall of the guide box 6 and the right inner wall of the box body 1. The front side of the spray pipe 24 is connected to the nozzle 25. The spray pipe 24 is fixed to the right side wall of the guide box 6 and the right inner wall of the box body 1 by the fixing ring 23 on both ends of the spray pipe 24 to support and fix the spray pipe 24. The water drawn out is sprayed out through the nozzle 25 on the front side of the spray pipe 24 to wash the surface of the rotating screen cylinder 10, so as to prevent impurities and particles from remaining in the holes and grooves of the screen cylinder 10 or sticking to the surface of the screen cylinder 10.

[0039] It should be noted that this utility model is a turbid circulating water tank filtration mechanism. First, the air pump 204, the first motor 207, the control panel 3, the second motor 11, and the pump 20 are connected to an external power source to supply power to the device.

[0040] The air tank 202 is fixed to the left side wall of the tank 1 by the connecting plate 201. After the air pump 204 is started, the gas is transported to the inside of the air tank 202 through the output pipe 205 for storage. The gas stored in the air tank 202 is distributed through the air outlet pipes 206 connected to the upper and lower sides. The right ends of the four air outlet pipes 206 penetrate the upper and lower sides of the left side wall of the tank 1, thereby introducing the gas into the inside of the tank 1. In the turbid circulating water pool, these gases can form microbubbles in the water. When the gas exists in the water in the form of microbubbles, due to the buoyancy of the bubbles, it can attach and combine with the suspended particles in the water, and carry the scum particles and other particles to float on the surface of the turbid circulating water.

[0041] When the first motor 207 starts, its output drives the first rotating rod 208 to rotate. When the first rotating rod 208 rotates, it drives the outer belt 212 through the first support ring 209 at the rear end. The belt 212 is connected to the second support ring 211 on the bottom second rotating rod 210, thereby driving the second rotating rod 210 and the second support ring 211 to rotate. This ensures that the rotation of the first rotating rod 208 drives the second rotating rod 210 to rotate synchronously. The first rotating rod 208 and the second rotating rod 210 are fixed to the outer side by the fixing ring 213, and the fixing ring 213 is connected to the stirring plate 214. This allows the first rotating rod 208 and the second rotating rod 210 to drive the stirring plate 214 to rotate. The stirring plates 214 on the upper and lower sides are arranged in a cross pattern, which can improve the stirring efficiency, make the air flotation process more uniform, and ensure that the microbubbles generated by the air pump 204 can fully contact and combine with more suspended particles, thereby improving the efficiency of air flotation separation.

[0042] After stirring, the floating impurities and some of the turbid circulating water will be pushed into the guide box 6 inside the baffle 5 by the rotating stirring plate 214 at the top. The turbid circulating water will be transferred to the inside of the sieve cylinder 10 through the transfer groove 7 and the second connecting pipe 8.

[0043] When the second motor 11 starts, the rotating shaft 12 on the output end drives the sieve cylinder 10 to rotate. The left end of the sieve cylinder 10 is connected to the second connecting pipe 8 through the pipe support ring 9, which supports the left end of the sieve cylinder 10. Turbid circulating water enters the sieve cylinder 10 through the second connecting pipe 8 and flows into the interior of the box 1 through the holes and grooves of the sieve cylinder 10. Impurities in the turbid circulating water will stick to the inner wall of the sieve cylinder 10. When the sieve cylinder 10 rotates, it will drive the impurities stuck to the inner wall to rotate. When it reaches a certain degree of rotation, the impurities will be scraped off by the scraper 16 on the top support plate 15 of the collection tank 14 and fall into the interior of the collection tank 14 for collection. After collection, the impurities will carry some of the turbid circulating water into the interior of the collection tank 14 through the sieve cylinder 10 and then flow into the interior of the drain pipe 17 along with some of the turbid circulating water to be discharged into the interior of the box 1.

[0044] When the pump 20 is started, it connects to the external pipes and water tank through the adapter pipe 21 at the input end to extract water. The extracted water is transported to the spray pipe 24 through the transmission pipe 22. The water flows in the spray pipe 24 and is sprayed out through the nozzle 25 to clean the sieve cylinder 10. This removes residues from the inside and outside surfaces of the sieve cylinder 10 and further improves the filtration efficiency of the sieve cylinder 10.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
