Description

Technical Field

[0001] This utility model relates to the field of denitrification catalyst cleaning technology, specifically a denitrification catalyst cleaning wastewater collection and processor. Background Technology

[0002] When cleaning denitrification catalysts, cleaning agents are typically sprayed or soaked onto the catalyst surface to remove accumulated dust, fly ash, and other contaminants. This process generates wastewater containing contaminants and cleaning agents. To prevent this wastewater from being directly discharged into the environment, a wastewater collector is installed in the system to collect the wastewater generated during the cleaning process. The wastewater collector is usually designed as a well-sealed container to effectively collect and store the cleaning wastewater.

[0003] However, before wastewater can be collected by a wastewater collector, suspended solids or larger particles in the wastewater need to be treated. Existing wastewater collectors usually use filtration to separate these particles. However, because denitrification produces a lot of wastewater, the filter plates will become clogged with floating solids or larger particles after a long filtration time, causing wastewater to overflow and pollute the environment. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater collection and processor for denitrification catalyst cleaning, in order to solve the problem mentioned in the background art that the filter plate will be blocked by floating objects or large particles after the filtration time is too long, resulting in wastewater overflow and causing environmental pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater collection and processor for cleaning denitrification catalysts, comprising a base plate, a filter box 1 fixedly connected to the upper surface of the base plate, a cover movably connected to the upper surface of the filter box 1, an inlet pipe fixedly connected to the upper surface of the cover, a connecting pipe fixedly connected to one outer surface of the filter box 1, a connecting box fixedly connected to the outer surface of the connecting pipe, a connecting pipe 1 fixedly connected to the lower end of one side of the filter box 1 and the connecting box, a water pump connected to the input end of the connecting pipe 1, a connecting pipe 2 connected to the output end of the water pump, a collection bucket fixedly connected to the outer end of the connecting pipe 2, an outlet fixedly connected to the lower end of one outer surface of the collection bucket, a feed inlet fixedly connected to the upper surface of the collection bucket, and a dense opening on the outer surface of the filter box 1 away from the connecting box. The filter box has a sealing groove, with a sealing plate engaged on its inner side. A pull plate is fixedly connected to the outer surface of the sealing plate, and a filter plate one is fixedly connected to the outer surface of the pull plate. An installation groove is slidably connected to the outer surface of the filter plate one. A limit strip is fixedly connected to the upper inner side of the filter box one. A connecting groove is opened on the inner side of the filter box one near the pull plate. A spring is fixedly connected to the inner side of the connecting groove. A sliding plate is fixedly connected to the upper surface of the spring. A fixing plate is fixedly connected to the outer surface of the sliding plate. An adjustment groove is slidably connected to the outer surface of the fixing plate. An installation frame one is fixedly connected to the inner side of the filter box one near the connecting box. A filter plate two is slidably connected to the inner side of the installation frame one. An installation frame two is fixedly connected to the inner side of the filter box one near the connecting pipe one. A filter plate three is slidably connected to the inner side of the installation frame two.

[0006] Preferably, a cylinder is fixedly connected to the upper surface of the collection bucket near the feed inlet, the output shaft of the cylinder is connected to a connecting plate, a motor is fixedly connected to the upper surface of the connecting plate, and a stirring blade is connected to the output shaft of the motor.

[0007] Preferably, the filter box and the connecting box are interconnected by a connecting pipe. The sealing groove is a rectangular recess, and there are two sets of sealing grooves. The sealing plate is plate-shaped and is engaged with the sealing groove. The mounting groove is a rectangular recess, and the filter plate is slidably connected to the inner side of the mounting groove. The limiting strip is elongated and there are four sets of limiting strips. The two sides of the filter plate are slidably connected to the limiting strips. Its function is to connect the filter box and the connecting box through the connecting pipe, so that when there is too much wastewater inside the filter box, it flows into the inner side of the connecting box through the connecting pipe, preventing wastewater from overflowing and causing environmental pollution. At the same time, the engagement of the sealing plate with the sealing groove prevents wastewater from flowing out through the gap between the filter plate and the mounting groove during filtration.

[0008] Preferably, the connecting groove is a rectangular groove, and the connecting groove is opened on the inner side of the filter box near the lower part of the mounting groove. The spring is spiral in shape, and multiple springs are fixedly connected between the inner side of the connecting groove and the sliding plate. When the filter plate is removed from the inner side of the filter box, the sliding plate will slide upward on the inner side of the connecting groove under the elastic action of the spring until it blocks the mounting groove, preventing wastewater from flowing out of the mounting groove.

[0009] Preferably, the slide plate is plate-shaped, and the adjustment groove is a rectangular groove. The adjustment groove is located on the outer surface of the filter box one, near the bottom of the pull plate. Its function is that after cleaning the filter plate one, when it needs to be reinstalled inside the filter box one, the fixing plate is slid downward inside the adjustment groove by sliding the fixing plate, thereby driving the slide plate to slide downward, exposing the installation groove, so that the filter plate one can be reinstalled inside the filter box one.

[0010] Preferably, both mounting frame one and mounting frame two are rectangular frames, and both filter plate two and mounting frame two are plate-shaped. Filter plate two is located at the connection between the connecting pipe and filter box one, and filter plate three is located at the connection between filter box one and connecting pipe one. Its function is that after filter plate one is removed, wastewater directly enters the inside of filter box one. Under the filtration effect of filter plate two and filter plate three, suspended solids or larger particles in the subsequent wastewater can be prevented from entering the inside of the connecting box or collection tank through the connecting pipe and connecting pipe one.

[0011] Preferably, the connecting plate is plate-shaped and movably connected above the collection tank. The stirring blade is fan-shaped and rotatably connected to the inside of the collection tank. Its function is to start the motor, causing the output shaft of the motor to drive the stirring blade to stir inside the collection tank. At the same time, by starting the cylinder, the output shaft of the cylinder extends and retracts, thereby driving the motor to rise and fall above the collection tank, thus causing the stirring blade to stir at different heights inside the collection tank, thereby making the reaction between wastewater and chemical reagents more complete.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By sliding the fixing plate, the fixing plate slides downward inside the adjustment groove, thereby driving the slide plate to slide downward, exposing the installation groove, and then reinstalling the filter plate into the inside of the filter box, thus facilitating the replacement of the filter plate.

[0013] 2. By starting the motor, the output shaft of the motor drives the stirring blades to stir inside the collection tank. At the same time, by starting the cylinder, the output shaft of the cylinder extends and retracts, thereby driving the motor to rise and fall above the collection tank. This causes the stirring blades to stir at different heights inside the collection tank, which makes the wastewater react more fully with the chemical reagents and prevents the reagents from settling at the bottom of the collection tank and failing to react with the wastewater, thus affecting the wastewater treatment efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A wastewater collection and processing unit for cleaning denitrification catalysts includes a base plate 1. A filter box 2 is fixedly connected to the upper surface of the base plate 1. A cover 3 is movably connected to the upper surface of the filter box 2. An inlet pipe 4 is fixedly connected to the upper surface of the cover 3. A connecting pipe 5 is fixedly connected to one outer surface of the filter box 2.

A connecting pipe 7 is fixedly connected to the lower end of one side of the filter box 2 and the connecting box 6. A water pump 8 is connected to the input end of the connecting pipe 7. A connecting pipe 9 is connected to the output end of the water pump 8. A collection bucket 10 is fixedly connected to the outer end of the connecting pipe 9. An outlet 11 is fixedly connected to the lower end of one outer surface of the collection bucket 10. An inlet 29 is fixedly connected to the upper surface of the collection bucket 10. A sealing groove 12 is formed on the outer surface of the filter box 2 away from the connecting box 6. A sealing plate 1 is engaged with the inner side of the sealing groove 12. 3. A pull plate 14 is fixedly connected to the outer surface of the sealing plate 13. A filter plate 15 is fixedly connected to the outer surface of the pull plate 14. An installation groove 30 is slidably connected to the outer surface of the filter plate 15. A limit strip 16 is fixedly connected to the upper inner side of the filter box 2. A connecting groove 17 is opened on the inner side of the filter box 2 near the pull plate 14. A spring 18 is fixedly connected to the inner side of the connecting groove 17. A sliding plate 19 is fixedly connected to the upper surface of the spring 18. A fixing plate 20 is fixedly connected to the outer surface of the sliding plate 19. An adjustment groove 21 is slidably connected to the outer surface of the fixing plate 20. An installation frame 22 is fixedly connected to the inner side of the filter box 2 near the connecting box 6. A filter plate 23 is slidably connected to the inner side of the installation frame 22. An installation frame 24 is fixedly connected to the inner side of the filter box 2 near the connecting pipe 7. A filter plate 35 is slidably connected to the inner side of the installation frame 24.

[0018] Furthermore, a cylinder 26 is fixedly connected to the upper surface of the collection tank 10 near the feed inlet 29. The output shaft of the cylinder 26 is connected to a connecting plate 27, and a motor 28 is fixedly connected to the upper surface of the connecting plate 27. The output shaft of the motor 28 is connected to a stirring blade 280. There are two sets of cylinders 26, which are controlled by a synchronous controller. The synchronous controller is existing technology and is not shown in the figure. The synchronous controller is electrically connected to the two cylinders 26. Its working principle is to accurately monitor the displacement and speed of the output shafts of the two cylinders 26. When a deviation is detected between the displacement or speed of the output shaft of one cylinder 26 and the other cylinder 26, the synchronous controller will automatically adjust the intake or exhaust volume of the cylinder 26 to ensure that the output shafts of the two cylinders 26 extend and retract synchronously. This drives the connecting plate 27 and the motor 28 to rise and fall smoothly above the collection tank 10, so as to achieve stable stirring of the stirring blade 280 at different heights inside the collection tank 10 and ensure that the wastewater and chemical reagents react fully.

[0019] Furthermore, the filter box 2 and the connecting box 6 are interconnected by the connecting pipe 5. The sealing groove 12 is a rectangular groove, and there are two sets of sealing grooves. The sealing plate 13 is plate-shaped and is engaged with the sealing groove 12. The mounting groove 30 is a rectangular groove, and the filter plate 15 is slidably connected to the inner side of the mounting groove 30. The limiting strip 16 is strip-shaped, and there are four sets of limiting strips. The two sides of the filter plate 15 are slidably connected to the limiting strip 16. Its function is to connect the filter box 2 and the connecting box 6 through the connecting pipe 5, so that when there is too much wastewater inside the filter box 2, it flows into the inner side of the connecting box 6 through the connecting pipe 5, preventing wastewater from overflowing and causing environmental pollution. At the same time, the sealing plate 13 is engaged with the sealing groove 12, thereby preventing wastewater from flowing out through the gap between the filter plate 15 and the mounting groove 30 during filtration.

[0020] Furthermore, the connecting groove 17 is a rectangular groove, and the connecting groove 17 is opened inside the filter box 2 near the lower part of the mounting groove 30. The spring 18 is spiral in shape, and multiple sets of springs 18 are fixedly connected between the inner side of the connecting groove 17 and the sliding plate 19. When the filter plate 15 is removed from the inner side of the filter box 2, the sliding plate 19 will slide upward on the inner side of the connecting groove 17 under the elastic action of the spring 18 until it blocks the mounting groove 30, preventing wastewater from flowing out of the mounting groove 30.

[0021] Furthermore, the slide plate 19 is plate-shaped, and the adjustment groove 21 is a rectangular groove. The adjustment groove 21 is located on the outer surface of the filter box 2 near the pull plate 14. Its function is that after cleaning the filter plate 15, when it is necessary to reinstall the filter plate 15 into the inner side of the filter box 2, the fixing plate 20 is slid down inside the adjustment groove 21 by sliding the fixing plate 20, thereby driving the slide plate 19 to slide down and expose the installation groove 30, so that the filter plate 15 can be reinstalled into the inner side of the filter box 2.

[0022] Furthermore, both mounting frame 1 22 and mounting frame 2 24 are rectangular frames, and both filter plate 2 23 and mounting frame 2 24 are plate-shaped. Filter plate 2 23 is located at the connection between the connecting pipe 5 and the filter box 1 2, and filter plate 3 25 is located at the connection between the filter box 1 2 and the connecting pipe 1 7. Its function is that after the filter plate 1 15 is removed, the wastewater directly enters the inside of the filter box 1 2. Under the filtration effect of filter plate 2 23 and filter plate 3 25, it can prevent suspended solids or larger particles in the subsequent wastewater from entering the inside of the connecting box 6 or the collection tank 10 through the connecting pipe 5 and the connecting pipe 1 7.

[0023] Furthermore, the connecting plate 27 is plate-shaped and is movably connected above the collection tank 10. The stirring blade 280 is fan-shaped and is rotatably connected to the inside of the collection tank 10. Its function is to start the motor 28, so that the output shaft of the motor 28 drives the stirring blade 280 to stir inside the collection tank 10. At the same time, by starting the cylinder 26, the output shaft of the cylinder 26 extends and retracts, thereby driving the motor 28 to rise and fall above the collection tank 10, thereby driving the stirring blade 280 to stir at different heights inside the collection tank 10, so that the wastewater reacts more fully with the chemical reagents.

[0024] Working principle: A filter box 2 is fixedly connected to the upper surface of the base plate 1. A cover 3 is movably connected to the upper surface of the filter box 2. A water inlet pipe 4 is fixedly connected to the upper surface of the cover 3. A connecting pipe 5 is fixedly connected to one outer surface of the filter box 2. A connecting box 6 is fixedly connected to the outer surface of the connecting pipe 5. A connecting pipe 7 is fixedly connected to the lower end of one side of the filter box 2 and the connecting box 6. A water pump 8 is connected to the input end of the connecting pipe 7. A connecting pipe 9 is connected to the output end of the water pump 8. A collection bucket 10 is fixedly connected to the outer end of the connecting pipe 9. A water outlet 11 is fixedly connected to the lower end of one outer surface of the collection bucket 10. A feed inlet 29 is fixedly connected to the upper surface of the collection bucket 10. A sealing groove is formed on the outer surface of the filter box 2 away from the connecting box 6. 12. A sealing plate 13 is engaged with the inner side of the sealing groove 12. A pull plate 14 is fixedly connected to the outer surface of the sealing plate 13. A filter plate 15 is fixedly connected to the outer surface of the pull plate 14. An installation groove 30 is slidably connected to the outer surface of the filter plate 15. A limit strip 16 is fixedly connected to the upper inner side of the filter box 2. A connecting groove 17 is opened on the inner side of the filter box 2 near the pull plate 14. A spring 18 is fixedly connected to the inner side of the connecting groove 17. A sliding plate 19 is fixedly connected to the upper surface of the spring 18. A fixing plate 20 is fixedly connected to the outer surface of the sliding plate 19. An adjustment groove 21 is slidably connected to the outer surface of the fixing plate 20. An installation frame 22 is fixedly connected to the inner side of the filter box 2 near the connecting box 6. A filter plate is slidably connected to the inner side of the installation frame 22. 23. A mounting frame 24 is fixedly connected to the inner side of filter box 2 near the connecting pipe 7. A filter plate 25 is slidably connected to the inner side of mounting frame 24. By connecting the outlet of the denitrification wastewater to the inlet pipe 4, the wastewater enters the inner side of filter box 2 through the inlet pipe 4. Under the filtration action of filter plate 15, suspended solids or larger particles in the wastewater are separated. When filter plate 15 needs to be cleaned or replaced after prolonged use, the sealing plate 13 is pulled out from the inner side of the sealing groove 12 by pulling the pull plate 14. This causes filter plate 15 to slide in the direction of pull plate 14 from the inner side of the limiting strip 16 until filter plate 15 is pulled out. The moment filter plate 15 is pulled out... Under the elastic action of spring 18, slide plate 19 will slide upward inside the connecting groove 17 until it blocks the mounting groove 30, preventing wastewater from flowing out of the mounting groove 30. At this time, the wastewater directly enters the inside of filter box 2. Under the filtering action of filter plate 23 and filter plate 25, it can prevent suspended solids or larger particles in the subsequent wastewater from entering the inside of the connecting box 6 or the collection bucket 10 through the connecting pipe 5 and connecting pipe 7. After filter plate 15 is processed, by sliding the fixing plate 20, the fixing plate 20 slides downward inside the adjusting groove 21, thereby driving slide plate 19 downward to expose the mounting groove 30. Then filter plate 15 is reinstalled inside the filter box 2, which facilitates the replacement of filter plate 15.

[0025] A cylinder 26 is fixedly connected to the upper surface of the collection tank 10 near the feed inlet 29. The output shaft of the cylinder 26 is connected to a connecting plate 27, and a motor 28 is fixedly connected to the upper surface of the connecting plate 27. The output shaft of the motor 28 is connected to a stirring blade 280. By starting the water pump 8, the filtered wastewater in the filter box 12 and the connecting box 6 is drawn through the connecting pipe 11 to the connecting pipe 22, allowing the wastewater to enter the inside of the collection tank 10. Then, chemical reagents are added to the inside of the collection tank 10 through the feed inlet 29, and then the pump 8 is started. The motor 28 is activated, causing its output shaft to drive the stirring blades 280 to stir inside the collection tank 10. Simultaneously, the cylinder 26 is activated, causing its output shaft to extend and retract, thereby driving the motor 28 to rise and fall above the collection tank 10. This causes the stirring blades 280 to stir at different heights inside the collection tank 10, ensuring a more complete reaction between the wastewater and the chemical reagents. This prevents the reagents from settling at the bottom of the collection tank 10 and failing to react with the wastewater, thus affecting the wastewater treatment efficiency.
