Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to an environmentally friendly sewage removal device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. In water conservancy projects, in order to avoid serious pollution of other water qualities by sewage, a decontamination process is usually carried out first to reduce the impact of impurities in sewage.

[0003] In existing wastewater treatment processes, due to the presence of large, irregularly shaped impurities, most methods first use filters to remove them. The filtered impurities then accumulate in a removal tank. When a certain amount of impurities accumulates, they need to be discharged from the sludge outlet. However, this discharge process typically requires a shutdown, which not only interrupts the wastewater treatment process and severely impacts its continuity but also significantly reduces overall treatment efficiency. This fails to meet the demands of large-scale, uninterrupted wastewater treatment in water conservancy projects, greatly hindering their progress. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, which involves filtering and removing large, irregular impurities from wastewater using a filter screen. The filtered impurities accumulate in the impurity removal box, and when a certain amount accumulates, they need to be discharged from the slag outlet. However, this process usually requires stopping the machine, which not only interrupts the wastewater treatment process and severely affects its continuity, but also significantly reduces the overall treatment efficiency. This makes it impossible to meet the needs of large-scale, uninterrupted wastewater treatment in water conservancy projects, greatly hindering the normal progress of these projects.

Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: This embodiment discloses an environmentally friendly wastewater removal device for water conservancy projects. Through the ingenious design of a first removal box 2, a second removal box 3, a control shaft 5, a control plate 6, and a drive mechanism 7, the control shaft 5 can be rotated as needed. The control shaft 5 drives the control plate 6 to rotate, thereby allowing the control plate 6 to control the flow direction of wastewater. When one removal box is performing removal operations, the other can clean impurities without stopping the machine. This effectively avoids interrupting the entire wastewater treatment process due to impurity cleaning, greatly improving the continuity and efficiency of wastewater treatment and meeting the needs of large-scale wastewater treatment in water conservancy projects. (Refer to...) Figures 1-6It mainly includes an inlet pipe 1, characterized in that: one end of the inlet pipe 1 is fixedly connected to a first impurity removal box 2 and a second impurity removal box 3; the ends of the first impurity removal box 2 and the second impurity removal box 3 away from the inlet pipe 1 are fixedly connected to an outlet pipe 4; a control shaft 5 is rotatably mounted on the inlet pipe 1; a control plate 6 is fixedly connected to the control shaft 5 located inside the inlet pipe 1, used to control the flow of wastewater to the first impurity removal box 2 or the second impurity removal box 3; a drive mechanism 7 capable of driving the control shaft 5 to rotate is installed at the upper end of the inlet pipe 1; the first impurity removal box... Both the first impurity removal box 2 and the second impurity removal box 3 are equipped with filter screens 13 for filtering wastewater. Both the first impurity removal box 2 and the second impurity removal box 3 have a slag outlet 8 at the lower end of one side. A sealing door 9 is installed on the slag outlet 8. Both the first impurity removal box 2 and the second impurity removal box 3 are rotatably mounted with crushing shafts 14. The crushing shafts 14 are driven by a first motor 10. Several crushing blades 15 are evenly spaced and fixedly connected on the crushing shafts 14 located inside the first impurity removal box 2 and the second impurity removal box 3 for crushing the filtered impurities. By installing a crushing shaft 14 and a crushing blade 15 in the first impurity removal box 2 and the second impurity removal box 3, the filtered impurities can be crushed. The volume of the crushed impurities is reduced, which not only facilitates subsequent cleaning and discharge and reduces the risk of blockage of the slag outlet 8, but also facilitates the further treatment and recycling of impurities, improves resource utilization, and reduces environmental pollution.

[0023] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The drive mechanism 7 includes a mounting frame 701, a worm gear 702, a drive motor 703, and a worm wheel 704. The mounting frame 701 is fixedly connected to the water inlet pipe 1. The drive motor 703 is fixedly mounted on the mounting frame 701. The worm gear 702 is fixedly mounted on the output shaft of the drive motor 703. The worm wheel 704, which meshes with the worm gear 702, is fixedly mounted on the control shaft 5. In actual use, the drive motor 703 is started, which drives the worm gear 702 to rotate. The worm gear 702 meshes with the worm wheel 704, causing the worm wheel 704 to rotate. The worm wheel 704 drives the control shaft 5 to rotate.

[0024] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The crushing shaft 14 and the slag outlet 8 are both located between the water inlet pipe 1 and the filter screen 13; this facilitates the crushing of the filtered impurities, thereby making it easier for the impurities to flow out from the slag outlet 8.

[0025] In this embodiment, a number of reinforcing rods are fixedly connected at even intervals on the control board 6, which can improve the structural strength of the control board 6 and thus effectively prevent the control board 6 from deforming or being damaged due to excessive force.

[0026] Example 2: Based on Embodiment 1, this embodiment discloses an environmentally friendly wastewater removal device for water conservancy projects, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 Both the first impurity removal box 2 and the second impurity removal box 3 are rotatably equipped with lead screws 11. The first impurity removal box 2 and the second impurity removal box 3 are equipped with linkage mechanisms 12 that can drive the two lead screws 11 to rotate. The lead screws 11 are threadedly connected to threaded sliders 16. The threaded sliders 16 are equipped with cleaning brushes 18 that can clean the filter screen 13 through adjusting components 17. Limiting components 19 are installed at both ends of the threaded sliders 16. In practical use, the linkage mechanism 12 rotates the two lead screws 11, and the lead screws 11 drive the corresponding threaded sliders 16 to rotate. However, under the limit of the limiting component 19, the threaded sliders 16 move up and down, which can clean the filter screen 13 and effectively prevent the filter screen 13 from being blocked and affecting the filtration effect.

[0027] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The linkage mechanism 12 includes a linkage shaft 1201, a driving bevel gear 1202, a driven bevel gear 1203, a driven gear 1204, a driving gear 1205, and a second motor 1206. A driven bevel gear 1203 is fixedly installed at the upper end of each lead screw 11. The linkage shaft 1201 is rotatably installed between the first impurity removal box 2 and the second impurity removal box 3. A driving bevel gear 1202 that can mesh with the corresponding driven bevel gear 1203 is fixedly installed at both ends of the linkage shaft 1201. A second motor 1206 is fixedly installed at the upper end of the first impurity removal box 2. A driving gear 1205 is fixedly installed on the output shaft of the second motor 1206. A driven gear 1204 that can mesh with the driving gear 1205 is fixedly installed on the linkage shaft 1201. In practical use, the second motor 1206 is started, which drives the drive gear 1205 to rotate. The drive gear 1205 meshes with the driven gear 1204, causing the driven gear 1204 to rotate. The driven gear 1204 drives the linkage shaft 1201 to rotate. The linkage shaft 1201 drives the drive bevel gears 1202 at both ends. The drive bevel gears 1202 mesh with the corresponding driven bevel gears 1203, causing the driven bevel gears 1203 to rotate. The driven bevel gears 1203 drive the lead screw 11 to rotate.

[0028] In this embodiment, refer to Figure 5 and Figure 6 The limiting component 19 includes a limiting rod 1901 and a rectangular plate 1902. Two limiting rods 1901 are fixedly connected to both sides of the interior of each of the first and second impurity removal boxes 2 and 3. A rectangular plate 1902 is fixedly connected to both ends of each of the threaded sliders 16. Each rectangular plate 1902 is slidably connected to the corresponding limiting rod 1901 through a through hole. Through the cooperative design of the limiting rods 1901 and the rectangular plate 1902, the threaded slider 16 can be limited, thereby effectively preventing the threaded slider 16 from rotating arbitrarily.

[0029] In this embodiment, refer to Figure 5 and Figure 6 The adjustment assembly 17 includes an adjustment bolt 1701, a mounting hole 1702, a circular plate 1703, and a retaining ring 1704. The adjustment bolt 1701 is threadedly connected to the threaded slider 16. The circular plate 1703 is fixedly connected to one end of the adjustment bolt 1701 near the cleaning brush 18. The cleaning brush 18 has a mounting hole 1702 that matches the circular plate 1703. The circular plate 1703 is rotatably installed in the mounting hole 1702. A retaining ring 1704 is fixedly installed in the mounting hole 1702 to prevent the circular plate 1703 from sliding out. When the cleaning brush 18 wears down over a long period of time and the bristles become shorter, rotating the adjustment bolt 1701 allows the cleaning brush 18 to move through the cooperation of the mounting hole 1702, the circular plate 1703, and the retaining ring 1704 until the bristles of the cleaning brush 18 fit against the filter screen 13, thereby improving the cleaning effect on the filter screen 13.

[0030] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The first and second cleaning boxes 2 and 3 are each provided with an opening 301 to facilitate the rotation of the adjusting bolt 1701. Each opening 301 is equipped with a sealing cover. The opening 301 facilitates the adjustment of the adjusting bolt 1701, and the position of the cleaning brush 18 can be adjusted as needed. The sealing cover can control the opening and closing of the opening 301.

[0031] In this embodiment, refer to Figure 5 and Figure 6 The threaded slider 16 has a groove 1601 that matches the cleaning brush 18. The groove 1601 helps to limit the cleaning brush 18 and prevent it from rotating randomly.

[0032] The working principle of an environmentally friendly sewage removal device for water conservancy projects according to the present invention is as follows: When sewage needs to be removed, the inlet pipe 1 is connected to the external pumping pipe, and the sewage to be removed is pumped into the inlet pipe 1 by the pumping pump. Due to the action of the control board 6, the sewage in the inlet pipe 1 will enter the second removal box 3. After being filtered by the filter screen 13 in the second removal box 3, it finally flows out from the outlet pipe 4. After filtration for a period of time, the drive motor 703 is started. The drive motor 703 drives the worm 702 to rotate. The worm 702 meshes with the worm wheel 704, causing the worm wheel 704 to rotate. The worm wheel 704 drives the control shaft 5 to rotate. The control shaft 5 drives the control plate 6 to rotate until the control plate 6 closes the second impurity removal box 3. At this time, the sewage in the inlet pipe 1 enters the first impurity removal box 2. After being filtered by the filter screen 13 in the first impurity removal box 2, it is finally discharged through the outlet pipe 4. During the discharge of wastewater through the first impurity removal box 2, the first motor 10 on the second impurity removal box 3 is started. The first motor 10 drives the crushing shaft 14 to rotate, and the crushing shaft 14 drives the crushing blade 15 to rotate, which can crush the impurities. Finally, the sealing door 9 is opened to discharge the crushed impurities from the slag outlet 8, thereby effectively avoiding the interruption of the entire wastewater treatment process due to the cleaning of impurities, greatly improving the continuity and efficiency of wastewater treatment, and meeting the needs of large-scale wastewater treatment in water conservancy projects.
