Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for concrete processing. Background Technology

[0002] As global attention to environmental protection continues to increase, countries and regions have introduced strict wastewater discharge standards. The concrete production process generates a large amount of wastewater, and if discharged directly without treatment, the cement, sand, silt, oil, and residual admixtures contained within will cause serious pollution to soil and water bodies.

[0003] Patent CN214680399U discloses a wastewater treatment device for concrete processing, including a treatment tank. A movable pipe is movably installed through the top of the treatment tank. Rotary screw holes are opened at the middle of both sides of the movable pipe. As the fixed sleeve moves horizontally, the trapezoidal first ejector block at its bottom moves on the inclined surface of the second ejector block at the top of the movable rod. After the inclined surfaces of the first and second ejector blocks come into contact, the movement of the first ejector block pushes the second ejector block, causing the movable rod to move vertically inside the movable pipe. The cleaning plate housed inside the movable tube is then moved out of its interior. Driven by the rotating shaft, the cleaning plate rotates from a vertical position to a horizontal position, ensuring that the movable rod moves the cleaning plate into the gap between the two sets of filter plates to push and clean the inner surface of the filter plates. This method is practical and suitable for widespread promotion and use. However, when cleaning impurities, the cleaned impurities will still remain inside the device, requiring the device to be shut down for processing. Therefore, a wastewater treatment device for concrete processing is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wastewater treatment device for concrete processing, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a wastewater treatment device for concrete processing, comprising a treatment tank, an inlet hopper fixedly connected to the top of the treatment tank, a cross plate fixedly connected to the inner wall of the inlet hopper, an output shaft rotatably connected to the inner wall of the cross plate, a filter plate fixedly connected to the inner wall of the treatment tank, a straight plate fixedly connected to the circumferential surface of the output shaft, an inclined hole plate fixedly connected to the inner wall of the treatment tank, a U-shaped plate fixedly connected to the top of the straight plate, and a drain valve installed on the top of the U-shaped plate. The leaking box has a rotating rod rotatably connected to its inner wall. A rubber wheel is fixedly connected to the circumferential surface of the rotating rod. A connecting plate is fixedly connected to the surface of the leaking box. An elastic rod is slidably connected to the inner wall of the connecting plate via a spring. A triangular block is fixedly connected to the right side of the elastic rod. An inclined block is fixedly connected to the inner wall of the U-shaped plate. An anti-clogging mechanism is provided on the circumferential surface of the output shaft to prevent sewage blockage. An alkalinity reduction mechanism is provided on the circumferential surface of the treatment tank to improve the sewage treatment effect. When wastewater from concrete needs treatment, it enters the device from the inlet hopper. This allows sand, gravel, and concrete debris accumulated at the bottom and in the holes of the inclined plate to be brushed into the drain box, thus collecting impurities and preventing them from falling into the treatment tank. This improves water quality, ensuring it meets environmental discharge standards and reducing the risk of water pollution. The circumferential surface of the rubber wheel contacts the bottom of the inclined plate. The drain box collects sediment and gravel particles from the wastewater. The surface of the triangular block contacts the surface of the inclined block. The brush scrapes away sediment accumulated at the bottom of the inclined plate. A motor is mounted on the top of the output shaft, driving its rotation. The circumferential surface of the output shaft contacts the inner wall of the filter plate, and the circumferential surface of the output shaft is rotatably connected to the inner wall of the inclined plate. When the drain box is full of impurities, workers can quickly clean the wastewater, reducing cleaning and maintenance time, improving work efficiency, and ensuring continuous and efficient equipment operation.

[0006] Preferably, the anti-clogging mechanism includes a second straight plate, which is fixedly connected to the circumferential surface of the output shaft. A push-out plate is fixedly connected to the bottom of the second straight plate, and a diagonal strip is fixedly connected to the front of the push-out plate. A baffle is slidably connected to the inner wall of the treatment tank, and a diagonal plate is fixedly connected to the right side of the baffle. A chamfered block is fixedly connected to the inner wall of the treatment tank, and a sliding rod is slidably connected to the inner wall of the chamfered block via a spring. A second U-shaped plate is fixedly connected to the top of the filter plate. The top of the inclined plate contacts the bottom of the push-out plate. The push-out plate is used to push out concrete sand and gravel particles mixed in with the wastewater. During wastewater treatment, it can push out sand and gravel from the edges and remove larger sand and gravel particles from the water. Separating these particles prevents them from entering subsequent treatment stages or discharge systems, which helps improve the efficiency and water quality of subsequent treatment, facilitates rapid discharge to meet standards, and avoids secondary pollution of water quality during treatment. The inner wall of the filter plate is fixedly connected to the circumferential surface of the sliding rod. During operation, the inclined bar will push the inclined plate upward through extrusion force. The baffle will be used to temporarily block the discharge outlet. During sewage treatment, the filter plate can move up and down to produce a screening effect, thereby screening out smaller sand and gravel particles, improving the filtration efficiency of the filter plate, enabling the equipment to more effectively remove solid impurities from sewage, and preventing clogging, keeping the filtration system unobstructed and stable.

[0007] Preferably, the outlet pipe includes an outlet pipe fixedly connected to the inner wall of the treatment tank. A fixing frame is fixedly connected to the circumferential surface of the treatment tank. A storage box is fixedly connected to the inner wall of the fixing frame. A discharge pipe is fixedly connected to the rear of the storage box. An inclined block is fixedly connected to the inner wall of the treatment tank. A moving rod is slidably connected to the inner wall of the inclined block via a spring. A closing plate is fixedly connected to the inner wall of the moving rod. A fixing strip is fixedly connected to the circumferential surface of the output shaft. An activated carbon plate is fixedly connected to the bottom of the fixing strip. During the sieving process, by adding an acidic regulator, the pH value of the water can be effectively reduced to neutral or near neutral, which helps to ensure that the discharged water quality meets environmental protection standards. To avoid environmental pollution, the closed discharge pipe prevents excessive addition of acidic regulators, which could lead to a low pH value, causing metal ion dissolution and secondary pollution. The circumferential surface of the discharge pipe is fixedly connected to the inner wall of the fixed frame. The storage box stores acidic regulators to neutralize the alkalinity in the wastewater. The circumferential surface of the discharge pipe is fixedly connected to the inner wall of the treatment tank. The top of the moving rod is in contact with the bottom of the filter plate. During wastewater treatment, it can adsorb organic matter, heavy metal ions, and other dissolved pollutants in the water. At the same time, it can increase the contact area between the fixed strip and the wastewater, promote the uniform distribution and wider contact of pollutants, and make the activated carbon more effective in removing harmful substances from the water.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This wastewater treatment equipment for concrete processing utilizes the coordinated operation of a treatment tank, inlet hopper, cross plate, output shaft, filter plate, straight plate, inclined perforated plate, U-shaped plate, drain box, rotating rod, brush plate, rubber wheel, connecting plate, elastic rod, triangular block, and inclined block. When wastewater from concrete processing needs treatment, the wastewater enters the device from the inlet hopper. This brushes away sand, gravel, and concrete debris accumulated at the bottom and in the holes of the inclined perforated plate, transferring them into the drain box. This process collects impurities, preventing them from falling into the treatment tank and improving water quality to meet environmental discharge standards, thus reducing the risk of water pollution. When the drain box is full of impurities, workers can quickly clean the wastewater, reducing cleaning and maintenance time, improving work efficiency, and ensuring continuous and efficient operation of the equipment.

[0010] 2. This wastewater treatment equipment for concrete processing, through the coordinated operation of the straight plate, the push-out plate, the inclined strip, the baffle, and the inclined plate, can push out the sand and gravel at the edge during the wastewater treatment process. This can separate larger sand and gravel particles from the water and prevent these particles from entering the subsequent treatment or discharge system, which helps to improve the efficiency and water quality of subsequent treatment, facilitates rapid discharge to meet standards, and avoids secondary pollution of water quality during the treatment process.

[0011] 3. This wastewater treatment equipment for concrete processing, through the coordinated operation of the chamfered block, sliding rod, and U-shaped plate, can cause the filter plate to move up and down during the wastewater treatment process, thereby producing a screening effect. This allows smaller sand and gravel particles to be screened out, improving the filtration efficiency of the filter plate. The equipment can more effectively remove solid impurities from the wastewater, while preventing clogging and maintaining the smooth and stable operation of the filtration system.

[0012] 4. This wastewater treatment equipment for concrete processing, through the coordinated operation of the outlet pipe, fixed frame, storage box, discharge pipe, inclined block, moving rod, and closing plate, can effectively reduce the pH value of the water to neutral or near neutral by adding an acidic regulator during the screening process. This helps ensure that the discharged water quality meets environmental protection standards and avoids environmental pollution. At the same time, by sealing the discharge pipe, it can also prevent the addition of too much acidic regulator, which could lead to an excessively low pH value, causing metal ions to dissolve and generate secondary pollution.

[0013] 5. This wastewater treatment equipment for concrete processing, through the coordinated operation of the fixed strips and activated carbon plates, can adsorb organic matter, heavy metal ions and other dissolved pollutants in the water during wastewater treatment. At the same time, it can increase the contact area between the fixed strips and the wastewater, promote the uniform distribution and wider contact of pollutants, and enable the activated carbon to remove harmful substances from the water more effectively.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0023] Please see Figures 1-7 One embodiment of the present invention is as follows: a wastewater treatment device for concrete processing, comprising a treatment tank 1, an inlet hopper 2 fixedly connected to the top of the treatment tank 1, a cross plate 3 fixedly connected to the inner wall of the inlet hopper 2, an output shaft 4 rotatably connected to the inner wall of the cross plate 3, a filter plate 5 fixedly connected to the inner wall of the treatment tank 1, a straight plate 6 fixedly connected to the circumferential surface of the output shaft 4, an inclined hole plate 7 fixedly connected to the inner wall of the treatment tank 1, a U-shaped plate 8 fixedly connected to the top of the straight plate 6, a drain box 9 installed on the top of the U-shaped plate 8, and the inner wall of the drain box 9 rotatably connected to the filter plate 1. A rotating rod 10 is connected to the inner wall of the leak box 9. A rubber wheel 12 is fixedly connected to the circumferential surface of the rotating rod 10. A connecting plate 13 is fixedly connected to the surface of the leak box 9. An elastic rod 14 is slidably connected to the inner wall of the connecting plate 13 through a spring. A triangular block 15 is fixedly connected to the right side of the elastic rod 14. An inclined block 16 is fixedly connected to the inner wall of the U-shaped plate 8. An anti-clogging mechanism 17 is provided on the circumferential surface of the output shaft 4 to prevent sewage blockage. An alkalinity reduction mechanism 18 is provided on the circumferential surface of the treatment tank 1 to improve the sewage treatment effect.

[0024] When wastewater from concrete needs to be treated, the wastewater enters the device from the inside of the inlet hopper 2. At this time, the motor starts and drives the output shaft 4 to rotate. The rotation of the output shaft 4 drives the straight plate 6 to rotate, which in turn drives the U-shaped plate 8 to rotate. The rotation of the U-shaped plate 8 drives the drain box 9 to rotate, which in turn drives the rotating rod 10 to rotate. The rotating rod 10 drives the rubber wheel 12 to rotate. During the rotation of the rubber wheel 12, it generates friction with the bottom of the inclined plate 7 and rotates on its own. The rotation of the rubber wheel 12 drives the rotating rod 10 to rotate, which in turn drives the brush plate 11 to rotate. This brushes the sand and gravel and concrete material accumulated at the bottom and in the holes of the inclined plate 7 into the drain box 9, thereby collecting the impurities and preventing them from falling into the treatment tank 1. This improves the water quality, making it meet environmental discharge standards and reducing the risk of water pollution.

[0025] The circumferential surface of the rubber wheel 12 is in contact with the bottom of the inclined plate 7. The drain box 9 is used to collect mud, sand and gravel particles in the sewage. The surface of the triangular block 15 is in contact with the surface of the inclined block 16. The brush plate 11 is used to scrape off the mud and sand accumulated at the bottom of the inclined plate 7. A motor is installed on the top of the output shaft 4, and the output shaft 4 will be driven by the motor to rotate. The circumferential surface of the output shaft 4 is in contact with the inner wall of the filter plate 5. The circumferential surface of the output shaft 4 is rotatably connected to the inner wall of the inclined plate 7.

[0026] When the impurities inside the drain box 9 are full, the staff opens the movable door on the inner wall of the treatment tank 1 by using the handle. At this time, the drain box 9 is pulled outward, which will cause the connecting plate 13 to move. The movement of the connecting plate 13 causes the elastic rod 14 to move outward, and the movement of the elastic rod 14 causes the triangular block 15 to move. During the movement of the triangular block 15, it will come into contact with the inclined block 16 and push the triangular block 15 to move to the left, thereby releasing the limit on the drain box 9, allowing it to be pulled out quickly. Then the impurities are poured out, so that the staff can quickly clean the impurities in the sewage, reducing the time for cleaning and maintenance, thereby improving work efficiency and ensuring the continuous and efficient operation of the equipment.

[0027] Working principle: When it is necessary to treat the wastewater generated from concrete, the wastewater will enter the device from the inside of the inlet hopper 2. At this time, the motor starts and drives the output shaft 4 to rotate. The rotation of the output shaft 4 drives the straight plate 6 to rotate, and the rotation of the rotating rod 10 drives the brush plate 11 to rotate. This brushes the sand and gravel and concrete materials accumulated at the bottom and in the holes of the inclined plate 7 into the inside of the drain box 9, thereby collecting the impurities and preventing them from falling into the treatment tank 1. During the movement of the triangular block 15, it will contact the inclined block 16 and push the triangular block 15 to the left, thereby releasing the limit on the drain box 9, so that the staff can quickly clean the impurities in the wastewater.

[0028] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the anti-clogging mechanism 17 includes a straight plate 171, which is fixedly connected to the circumferential surface of the output shaft 4. A push-out plate 172 is fixedly connected to the bottom of the straight plate 171, and an inclined strip 173 is fixedly connected to the front of the push-out plate 172. A baffle 174 is slidably connected to the inner wall of the treatment tank 1, and an inclined plate 175 is fixedly connected to the right side of the baffle 174. A chamfered block 176 is fixedly connected to the inner wall of the treatment tank 1, and a sliding rod 177 is slidably connected to the inner wall of the chamfered block 176 by a spring. A U-shaped plate 178 is fixedly connected to the top of the filter plate 5. The top of the inclined hole plate 7 is in contact with the bottom of the push-out plate 172, and the push-out plate 172 is used to push out concrete sand and gravel particles mixed in with the sewage.

[0029] During the wastewater treatment process, the output shaft 4 rotates, driving the straight plate 171 to rotate. The straight plate 171 rotates, driving the ejector plate 172 to rotate. When the ejector plate 172 rotates, it can cooperate with the inclined plate 7, pushing the larger sand and gravel particles accumulated on the top of the inclined plate 7 to the edge of the inclined plate 7. Then, the ejector plate 172 rotates, driving the inclined bar 173 to rotate. During the rotation of the inclined bar 173, it will contact the top of the inclined plate 175 and push the inclined plate 175 upward through the squeezing force of the inclined surface. The upward movement of the inclined plate 175 will drive the baffle 174 to move upward, thereby pushing out the sand and gravel on the edge. This can separate the larger sand and gravel particles in the wastewater from the water, preventing these particles from entering the subsequent treatment stage or discharge system. This helps to improve the efficiency and water quality of subsequent treatment, facilitates rapid discharge to meet standards, and avoids secondary pollution of water quality during the treatment process.

[0030] The inner wall of the filter plate 5 is fixedly connected to the circumferential surface of the sliding rod 177. During operation, the inclined bar 173 will push the inclined plate 175 upward through the extrusion force, and the baffle 174 will be used to temporarily block the outlet.

[0031] During the wastewater treatment process, the straight plate 6 rotates and comes into contact with the U-shaped plate 178, squeezing it downwards. This downward movement of the U-shaped plate 178 causes the sliding rod 177 to move downwards, compressing the spring on its surface. As the straight plate 6 passes the U-shaped plate 178, the sliding rod 177 returns to its original position via the spring and moves upwards, causing the filter plate 5 to move upwards. This up-and-down movement of the filter plate 5 creates a sieving effect, allowing smaller sand and gravel particles to be screened out. This improves the filtration efficiency of the filter plate 5, enabling the equipment to more effectively remove solid impurities from wastewater while preventing clogging and maintaining the smooth and stable operation of the filtration system.

[0032] Working principle: During the sewage treatment process, the output shaft 4 rotates, driving the straight plate 171 to rotate. The rotation of the straight plate 171 drives the push plate 172 to rotate, contacting the top of the inclined plate 175. The inclined plate 175 is pushed upward by the squeezing force of the inclined surface. The upward movement of the inclined plate 175 drives the baffle 174 to move upward, thereby pushing out the sand and gravel on the edge. Larger sand and gravel particles in the sewage can be separated from the water. The U-shaped plate 178 moves downward, driving the sliding rod 177 to move downward. The downward movement of the sliding rod 177 compresses the spring on the surface of the sliding rod 177. When the straight plate 6 passes the U-shaped plate 178, the sliding rod 177 will return to its original position and move upward by the spring, driving the filter plate 5 to move upward. This allows the filter plate 5 to move up and down, producing a sieving effect.

[0033] The water outlet pipe 181 includes a water outlet pipe 181, which is fixedly connected to the inner wall of the treatment tank 1. A fixing frame 182 is fixedly connected to the circumferential surface of the treatment tank 1. A storage box 183 is fixedly connected to the inner wall of the fixing frame 182. A discharge pipe 184 is fixedly connected to the rear of the storage box 183. An angled block 185 is fixedly connected to the inner wall of the treatment tank 1. A moving rod 186 is slidably connected to the inner wall of the angled block 185 by a spring. A closing plate 187 is fixedly connected to the inner wall of the moving rod 186. A fixing strip 188 is fixedly connected to the circumferential surface of the output shaft 4. An activated carbon plate 189 is fixedly connected to the bottom of the fixing strip 188.

[0034] During the sieving process, the filter plate 5 moves downward, causing the moving rod 186 to move downward. The downward movement of the moving rod 186 compresses the spring and causes the closing plate 187 to move downward, thereby sealing the outlet of the discharge pipe 184. This prevents the acidic regulator in the storage box 183 from being discharged temporarily. When the filter plate 5 moves upward, the moving rod 186 will return to its original position and move upward through the spring, thereby causing the closing plate 187 to move upward and open the outlet of the discharge pipe 184, allowing the acidic regulator in the storage box 183 to be discharged normally. Thus, by adding the acidic regulator, the pH value of the water can be effectively reduced and adjusted to neutral or near neutral, which helps to ensure that the discharged water quality meets environmental protection standards and avoids environmental pollution. At the same time, by sealing the discharge pipe 184, it can also prevent the addition of too much acidic regulator, which would lead to an excessively low pH value and cause metal ions to dissolve, resulting in secondary pollution.

[0035] The circumferential surface of the outlet pipe 181 is fixedly connected to the inner wall of the fixed frame 182. The storage box 183 will store acid regulators to neutralize the alkalinity in the sewage. The circumferential surface of the discharge pipe 184 is fixedly connected to the inner wall of the treatment tank 1. The top of the moving rod 186 is in contact with the bottom of the filter plate 5.

[0036] During wastewater treatment, the output shaft 4 rotates, causing the fixed strip 188 to rotate. The rotation of the fixed strip 188 causes the activated carbon plate 189 to rotate, thereby adsorbing organic matter, heavy metal ions and other dissolved pollutants in the water. At the same time, it can increase the contact area between the fixed strip 188 and the wastewater, promote the uniform distribution and wider contact of pollutants, and enable the activated carbon to remove harmful substances from the water more effectively.

[0037] Working principle: During the screening process, the filter plate 5 moves downward, driving the moving rod 186 downward. The downward movement of the moving rod 186 compresses the spring and drives the closing plate 187 downward, thereby sealing the outlet of the discharge pipe 184. This allows the acidic regulator in the storage box 183 to be discharged normally. By adding the acidic regulator, the pH value of the water can be effectively reduced to neutral or near neutral. At the same time, by sealing the discharge pipe 184, excessive addition of acidic regulator can be avoided, which would lead to an excessively low pH value, causing metal ions to dissolve and generate secondary pollution. During wastewater treatment, the output shaft 4 rotates, driving the fixed bar 188 to rotate. The rotation of the fixed bar 188 drives the activated carbon plate 189 to rotate, which increases the contact area between the fixed bar 188 and the wastewater, allowing the activated carbon to remove harmful substances from the water more effectively.

[0038] This invention provides a wastewater treatment device for concrete processing. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
