Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater sedimentation device for water conservancy construction. Background Technology

[0002] The main function of sedimentation in wastewater treatment is to use gravity and the difference in settling velocity of suspended solids in wastewater to cause them to settle. Sedimentation tanks are an important part of wastewater treatment systems and are mainly used for the preliminary treatment in the wastewater purification process.

[0003] According to a publicized wastewater sedimentation device for water conservancy construction (publication number: CN220405069U), the sedimentation component in the above application adopts a dual filtration structure to further purify the wastewater. At the same time, a slowly rotating cleaning brush is also installed on the inner side to clean the cylinder wall during the wastewater precipitation process, so as to avoid the mesh surface from clogging and affecting the precipitation speed.

[0004] However, in actual use, the above-mentioned equipment uses a cleaning brush to clean the filter cylinder wall to prevent the risk of screen blockage. However, during the cleaning process, impurities inside the sewage can become embedded in the cleaning brush, causing secondary pollution to the cylinder wall during subsequent cleaning and thus reducing the sewage precipitation rate. In view of this, we propose a sewage sedimentation device for water conservancy construction. Utility Model Content

[0005] The purpose of this invention is to provide a sewage sedimentation device for water conservancy construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage sedimentation device for water conservancy construction, comprising a sedimentation shell, a drain pipe provided on the side wall of the sedimentation shell, and a sedimentation structure provided inside the sedimentation shell, the sedimentation structure comprising:

[0007] A fixing plate is fixedly connected to the inner wall of the deposition shell. The surface of the fixing plate is provided with an insertion hole. The inner wall of the insertion hole is adapted to the outer wall of the positioning rod. A sieve plate is fixedly connected to the top of the positioning rod. A handle is fixedly connected to the top of the sieve plate.

[0008] A sedimentation tank is fixedly connected to the bottom of the sieve plate. A filter frame is installed inside the sedimentation tank. An embedded block is fixedly connected to the surface of the filter frame. The outer wall of the embedded block is adapted to the inner wall of the embedded groove. A through hole is opened through the bottom of the sedimentation tank. An activated carbon layer is installed at the top of the through hole to remove harmful substances such as heavy metals, toxins, and drug residues from the water.

[0009] Preferably, the outer wall of the sieve plate is adapted to the inner wall of the sedimentation shell, and the sieve plate has large sieve holes, which allows sewage to enter the sedimentation shell through its surface, and at the same time facilitates the installation of the sedimentation tank.

[0010] Preferably, the inner wall of the sedimentation tank is provided with an embedding groove, which limits the installation position of the filter frame.

[0011] Preferably, the embedding block is T-shaped, and the T-shape of the embedding block prevents the filter frame from shifting due to the impact of sewage.

[0012] Preferably, the upper surface of the handle has an inclined surface, and a drain hole is formed through the surface of the handle.

[0013] Preferably, the inclined surface is inclined, and the end of the inclined surface near the center of the handle is higher than the end of the inclined surface away from the center of the handle.

[0014] Compared with the prior art, this utility model provides a sewage sedimentation device for water conservancy construction, which has the following beneficial effects:

[0015] 1. This sewage sedimentation device for water conservancy construction, through the combination of insertion holes and positioning rods, allows for the quick installation or removal of the screen plate and sedimentation tank inside the sedimentation shell. The embedded block and embedded groove enable the filter frame to be quickly separated from the sedimentation tank, thus facilitating cleaning. This avoids secondary pollution caused by impurities embedding inside the filter screen when cleaning it with a cleaning brush, reducing the risks associated with cleaning the filter screen and ensuring the sedimentation speed.

[0016] 2. This sewage sedimentation device for water conservancy construction avoids the risk of impurities accumulating on the handle and leaking by setting an inclined surface, and the sewage discharge hole reduces the accumulation of impurities in the gap between the handle and the screen plate when they flow in with sewage, thus ensuring the sedimentation of sewage.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: a sewage sedimentation device for water conservancy construction, including a sedimentation shell 1, a drain pipe 2 opened on the side wall of the sedimentation shell 1, and a sedimentation structure inside the sedimentation shell 1, the sedimentation structure including a fixing plate 3, a hole 4, a positioning rod 5, a sieve plate 6, a handle 7, a sedimentation tank 8, a filter frame 9, an embedding block 10, an embedding groove 11, and a through hole 12.

[0024] In an embodiment of this utility model, a fixing plate 3 is fixedly connected to the inner wall of the sedimentation shell 1. An insertion hole 4 is provided on the surface of the fixing plate 3. The inner wall of the insertion hole 4 is adapted to the outer wall of the positioning rod 5. A sieve plate 6 is fixedly connected to the top of the positioning rod 5. A handle 7 is fixedly connected to the top of the sieve plate 6. A sedimentation tank 8 is fixedly connected to the bottom of the sieve plate 6. A filter frame 9 is provided inside the sedimentation tank 8. An embedding block 10 is fixedly connected to the surface of the filter frame 9. The outer wall of the embedding block 10 is adapted to the inner wall of the embedding groove 11. A through hole 12 is provided through the bottom of the sedimentation tank 8.

[0025] In one embodiment of this utility model, the outer wall of the sieve plate 6 is adapted to the inner wall of the sedimentation shell 1. The inner wall of the sedimentation tank 8 is provided with an embedding groove 11. The embedding block 10 is T-shaped. The upper surface of the handle 7 is provided with an inclined surface 14. There are two sets of inclined surfaces 14, and the two sets of inclined surfaces 14 are mirror images of each other with the center point of the handle 7 as the axis of symmetry. The surface of the handle 7 is provided with a drain hole 13. The inclined surface 14 is inclined. The end of the inclined surface 14 near the center of the handle 7 is higher than the end of the inclined surface 14 away from the center of the handle 7. The inner wall of the sedimentation shell 1 is provided with an inclined plate. The inclined plate is inclined towards the side of the drain pipe 2. The surface of the sedimentation tank 8 is provided with a door. The top of the sedimentation tank 8 is open. The filter frame 9 is U-shaped. The inner surface of the U-shaped filter frame 9 is fixedly installed with a filter screen for filtering sewage.

[0026] In this invention, wastewater is poured into the sedimentation shell 1. The wastewater falls into the sedimentation tank 8 through the sieve holes on the surface of the sieve plate 6. Upon entering, the wastewater accumulates at the opening of the sedimentation shell 1. As the wastewater enters the sedimentation shell 1, it comes into contact with the handle 7. The inclined surfaces 14 on both sides prevent impurities contained within the wastewater from accumulating on the surface of the handle 7. Simultaneously, the drain hole 13 prevents impurities from accumulating inside the handle 7. After falling, the wastewater is filtered through a filter screen, which intercepts impurities. The wastewater then passes through the through hole 1. 2. The wastewater falls into the sedimentation shell 1 for sedimentation and is finally discharged through the drain pipe 2. When it is necessary to clean the impurities inside the wastewater, first hold the handle 7 and lift it upwards so that the positioning rod 5 gradually disengages from the top of the insertion hole 4 until the screen plate 6 drives the sedimentation tank 8 out of the sedimentation shell 1. Open the door of the sedimentation tank 8 and pull the filter frame 9. As the filter frame 9 moves, it drives the embedded block 10 to slide inside the embedded groove 11 until the filter frame 9 is removed from the sedimentation tank 8, which makes it easier to clean and improves the sedimentation effect of the wastewater.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
