Description

Technical Field

[0001] This utility model relates to a wastewater treatment device, and more particularly to a wastewater treatment device containing a concrete quick-setting agent for use in the field of construction wastewater treatment. Background Technology

[0002] With the rapid development of the construction industry, concrete-related industries are also developing rapidly, and the number of concrete mixing plants is increasing day by day, resulting in more and more concrete wastewater. If the concrete wastewater is discharged directly, it will cause great pollution to the environment.

[0003] When treating concrete wastewater, accelerators are usually added and stirred to allow the accelerators to mix with the wastewater, accelerating the coagulation of solid particles and organic matter in the wastewater, forming larger particles that are easier to settle or filter. During separation, a filter screen is usually used for solid-liquid separation.

[0004] After filtration through the filter screen, it is necessary to frequently remove the filter screen and clean its surface impurities with scrapers, brushes, etc. This can easily cause deformation and damage to the filter screen, which not only increases the number of operation steps and reduces the efficiency of wastewater treatment, but also shortens the service life of the filter screen. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that when treating wastewater containing quick-coagulants through a filter screen, the filter screen needs to be removed and cleaned frequently, which not only increases the number of operation steps and reduces the efficiency of wastewater treatment, but also shortens the service life of the filter screen.

[0006] To address the aforementioned problems, this utility model provides a wastewater treatment device containing a concrete quick-setting agent, comprising a treatment tank. The inner wall of the treatment tank is equipped with a filter assembly, which includes an adjustment box. Fixed shafts are fixedly connected to both the front and rear ends of the adjustment box. The ends of the two fixed shafts that are furthest apart rotatably penetrate the treatment tank. A filter plate is fixedly connected to the upper left side of the adjustment box. An L-shaped lifting plate is provided inside the adjustment box. A rubber plate is fixedly connected to the lower end of the lifting plate. Multiple fixed rods and a miniature cylinder are fixedly connected to the inner bottom wall of the adjustment box. The upper ends of the fixed rods sequentially traverse the rubber plate and the lifting plate. The upper end of the miniature cylinder is fixedly connected to the lower end of the rubber plate. The right end of the regulating box is fixedly connected to a sliding plate, and the right inner wall of the treatment box is fixedly connected to a positioning plate. The lower end of the sliding plate is provided with multiple springs, and the upper end of the positioning plate is fixedly connected with multiple sliding rods corresponding to the multiple springs. The upper ends of the sliding rods move sequentially through the springs and the sliding plate. The lower middle part of the regulating box is fixedly connected to a vibration motor. The left end of the treatment box is fixedly connected to a collection assembly, which includes an L-shaped plate. The upper end of the L-shaped plate is provided with a collection box, and the upper end of the collection box is fixedly connected to a baffle. The upper middle part of the treatment box is fixedly connected to a water inlet pipe, and the lower right end of the treatment box is fixedly connected to a water outlet pipe. An electric valve is fixedly installed on the outer ring of the water outlet pipe.

[0007] In the aforementioned wastewater treatment device containing concrete quick-setting agent, after solid-liquid separation of wastewater, impurities can be collected, and the filter components can be cleaned simultaneously, eliminating the need for manual cleaning of the filter screen and improving wastewater treatment efficiency.

[0008] As a further improvement of this application, the collection box is located below the adjustment box, and the vertical distance between the left end of the adjustment box and the collection box is smaller than the vertical distance between the right end of the adjustment box and the collection box.

[0009] As a further improvement of this application, the end of the collection box near the adjustment box is at the same level as the left inner wall of the processing box, and the left end of the baffle is at the same level as the left end of the collection box.

[0010] As a further improvement of this application, the upper end of the fixing rod is at the same level as the upper end of the filter plate, and the upper end of the sliding plate is chiseled with multiple grooves corresponding to multiple sliding rods. The grooves are straight and round, and the two ends of the spring are fixedly connected to the sliding plate and the positioning plate respectively.

[0011] As another improvement of this application, there are two filtering components and two collecting components. The two adjustment boxes are tilted in opposite directions, and the two collecting components correspond to the lower ends of the two adjustment boxes respectively.

[0012] As another improvement of this application, a liquid level sensor is fixedly connected to the lower end of the processing tank, and the upper end of the liquid level sensor is fixedly inserted into the inner cavity of the processing tank, with the upper end of the liquid level sensor located below the collection assembly on the lower side.

[0013] In summary, in practical applications, wastewater falls onto the surface of the lifting plate through the inlet pipe and flows towards the filter plate. Solid impurities in the wastewater are blocked by the fixing rod and the filter plate. The wastewater passes through the filter plate, flows into the bottom of the treatment tank, and is then discharged through the outlet pipe. After the wastewater is treated, the collection box can be pushed into the treatment tank, and the micro cylinder can be activated to extend and move the lifting plate upward until it is aligned with the top of the filter plate. At this point, impurities on the surface of the lifting plate are exposed and fall into the collection box. Simultaneously, the vibration motor can be activated to vibrate the adjustment box, and the sliding plate shakes through the extension and contraction of the spring, thereby accelerating the sliding of impurities. This eliminates the need for frequent removal of the filter screen for cleaning, improves wastewater treatment efficiency, and facilitates use by staff. Attached Figure Description

[0024] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1 The diagram shows a wastewater treatment device containing a concrete quick-setting agent, comprising a treatment tank 1, a filter assembly on the inner wall of the treatment tank 1, a collection assembly fixedly connected to the left end of the treatment tank 1, the collection assembly including an L-shaped plate 13 supporting a collection box 14, the collection box 14 being located at the upper end of the L-shaped plate 13, a baffle 15 fixedly connected to the upper end of the collection box 14 limiting its position, an inlet pipe fixedly connected to the middle of the upper end of the treatment tank 1, and the right end of the treatment tank 1... The lower end is fixedly connected to a water outlet pipe 17, and an electric valve is fixedly installed on the outer ring of the water outlet pipe 17. The collection box 14 is located below the regulating box 2. The vertical distance between the left end of the regulating box 2 and the collection box 14 is less than the vertical distance between the right end of the regulating box 2 and the collection box 14. The regulating box 2 is in an inclined state to facilitate the flow of wastewater. The end of the collection box 14 near the regulating box 2 is on the same horizontal plane as the left inner wall of the treatment tank 1. The left end of the baffle 15 is on the same horizontal plane as the left end of the collection box 14.

[0027] Figure 2 , Figure 3 , Figure 4 and Figure 5The filter assembly includes an adjustment box 2, with fixed shafts 3 fixedly connected to both the front and rear ends of the adjustment box 2. The ends of the two fixed shafts 3 that are far apart rotatably pass through the treatment box 1. A filter plate 4 is fixedly connected to the upper left side of the adjustment box 2, which filters wastewater. An L-shaped lifting plate 5 is provided inside the adjustment box 2. A rubber plate 6 is fixedly connected to the lower end of the lifting plate 5, which can wrap around the fixed rods 7, effectively preventing wastewater from flowing into the adjustment box 2. Multiple fixed rods 7 and miniature cylinders 8 are fixedly connected to the inner bottom wall of the adjustment box 2. Those skilled in the art can select a suitable model of miniature cylinder 8 according to actual needs, such as MI10-25SCA. The fixed rods 7 can act as obstruction rods to block solids in the wastewater. The miniature cylinders 8 can push the lifting plate 5 upwards, thus exposing solid impurities on the surface of the lifting plate 5. The upper end of the fixed rod 7 sequentially moves through the rubber plate 6 and the lifting plate 5. The upper end of the miniature cylinder 8 is fixedly connected to the lower end of the rubber plate 6. A sliding plate 9 is fixedly connected to the right end of the adjusting box 2, and a positioning plate 10 is fixedly connected to the right inner wall of the processing box 1. Multiple springs 11 are provided at the lower end of the sliding plate 9, and multiple sliding rods 12 corresponding to the multiple springs 11 are fixedly connected to the upper end of the positioning plate 10. The upper ends of the sliding rods 12 pass through the springs 11 and the sliding plate 9 in sequence. The upper end of the fixed rod 7 is at the same level as the upper end of the filter plate 4. Multiple sliding grooves corresponding to the multiple sliding rods 12 are carved at the upper end of the sliding plate 9. The sliding grooves are straight and round. The two ends of the springs 11 are fixedly connected to the sliding plate 9 and the positioning plate 10 respectively. A vibration motor 16 is fixedly connected to the lower middle part of the adjusting box 2. Those skilled in the art can select a suitable model of vibration motor 16 according to actual needs, such as Yzo-20-6. When the vibration motor 16 is started, it can drive the adjusting box 2 to vibrate, causing the springs 11 to deform and drive the sliding plate 9 to move up and down. The adjusting box 2 rotates around the fixed shaft 3, thereby causing the impurities on the lifting plate 5 to slide off.

[0028] In use, wastewater falls onto the surface of the lifting plate 5 through the inlet pipe and flows towards the filter plate 4. Solid impurities in the wastewater are blocked by the fixing rod 7 and the filter plate 4. The wastewater passes through the filter plate 4 and flows into the bottom of the treatment tank 1, and then is discharged through the outlet pipe 17. After the wastewater is treated, the collection box 14 can be pushed into the treatment tank 1. The micro cylinder 8 is activated to extend and move the lifting plate 5 upward until it is aligned with the upper end of the filter plate 4. At this time, the impurities on the surface of the lifting plate 5 are exposed and fall into the collection box 14. At the same time, the vibration motor 16 can be activated to drive the adjustment box 2 to vibrate. The slide plate 9 vibrates through the extension and retraction of the spring 11, thereby accelerating the sliding of impurities. There is no need to frequently remove the filter screen for cleaning, which improves the wastewater treatment efficiency and makes it easier for staff to use.

[0029] Second implementation method:

[0030] This embodiment adds a filtering component and a collection component to the first embodiment, while the rest remains the same as the first embodiment.

[0031] Figure 7 As shown: there are two filtering components and two collecting components. The two regulating boxes 2 are tilted in opposite directions. The two collecting components correspond to the lower ends of the two regulating boxes 2 respectively.

[0032] When in use, the wastewater is treated through two filter components, which can effectively prevent impurities in the wastewater from being not completely cleaned, thus improving the wastewater treatment effect.

[0033] The third implementation method:

[0034] This embodiment adds a liquid level sensor 18 to the second embodiment, while the rest remains the same as the first embodiment.

[0035] Figure 8 As shown: A liquid level sensor 18 is fixedly connected to the lower end of the processing tank 1. Those skilled in the art can select a suitable model of liquid level sensor 18 according to actual needs, such as FBS-350LSN-24V (4 / 20mA)-F70. The upper end of the liquid level sensor 18 is fixedly inserted into the inner cavity of the processing tank 1, and the upper end of the liquid level sensor 18 is located below the collection assembly on the lower side.

[0036] During use, the liquid level sensor 18 monitors the volume of wastewater in the treatment tank 1 in real time, effectively preventing the liquid level of wastewater in the treatment tank 1 from being higher than the liquid level of the collection box 14, thereby effectively preventing wastewater from overflowing from the treatment tank 1 through the gap between the collection box 14 and the treatment tank 1.

[0037] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
