Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a river sewage treatment sediment primary filtration device. Background Art

[0002] In the complex process of river wastewater treatment, initial sediment filtration plays a crucial role. This step is crucial because it effectively removes large particles of impurities such as silt, rocks, and branches carried by the wastewater. These impurities not only damage subsequent water purification equipment and reduce its efficiency, but can also become a source of water pollution. Therefore, initial sediment filtration provides cleaner and more stable water inlet conditions for subsequent water purification steps, ensuring smooth operation of the entire wastewater treatment process.

[0003] Existing methods for primary sediment filtration often rely on traditional filtration equipment, which has inherent flaws in design and use. First, in terms of filtration efficiency, traditional equipment often suffers from clogging and wear of filter media (such as screens and filter cloths), leading to reduced filtration speeds and the need for frequent cleaning or replacement. This not only complicates equipment maintenance but also impacts the continuity and stability of wastewater treatment.

[0004] Secondly, the slag discharge process of traditional equipment also has many inconveniences. Due to unreasonable slag discharge port design or inflexible slag discharge mechanism, impurities such as mud and sand accumulate inside the equipment, making it difficult to completely discharge. This not only reduces the equipment's filtration effect but may also cause equipment failure. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a river sewage treatment sediment primary filtration device to solve the problems that the sewage primary filtration process is inefficient and inconvenient to clean.

[0006] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a river sewage treatment sediment primary filtration equipment, comprising a main frame, a water filter box is mounted on the main frame; a water inlet is reserved on the top of the water filter box, and a slag discharge port is reserved on one side thereof; a filter plate is provided in the water filter box which is inclined toward the slag discharge port; the bottom of the water filter box is connected to a water collecting box located below the filter plate, and a drainage pipe is reserved on the water collecting box; a slag collection trough is also arranged along the outside of the slag discharge port of the water filter box, and a slag collection box is installed at the discharge end of the slag collection trough.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the filter plates are distributed in multiple steps along the slag discharge direction.

[0009] Furthermore, a grid-shaped drain rack is arranged at the connection between the water collecting tank and the water filtering tank.

[0010] Furthermore, the inner cavity size of the water filter box narrows from top to bottom.

[0011] Furthermore, a vibration mechanism connected to the water filter box is also provided on the main frame.

[0012] Furthermore, the vibration mechanism includes a plurality of vibration springs installed between the main frame and the water filter box, and a vibration motor arranged on the water filter box.

[0013] Moreover, the river sewage treatment sediment primary filtration equipment provided by the present invention has at least the following beneficial effects compared with the prior art:

[0014] The multi-level stepped filter plate design significantly improves filtration efficiency and accuracy. By gradually depositing impurities such as mud and sand, it effectively slows down the water flow rate, reduces the risk of filter plate clogging, and ensures the continuous and stable operation of the equipment.

[0015] The setting of the vibration mechanism further enhances the performance of the equipment. Through the coordinated action of the vibration motor and the vibration spring, the accumulation on the filter plate is effectively loosened, preventing the occurrence of blockage. At the same time, it promotes the flushing effect of water flow, improves the filtering effect, and extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, the river sewage treatment sediment primary filtration equipment of this practical design includes a main frame 1, on which a water filter box 2 is mounted; a water inlet is reserved at the top of the water filter box 2, and a slag discharge port is reserved on one side thereof; a filter plate 3 is provided in the water filter box 2 which is inclined toward the slag discharge port; the bottom of the water filter box 2 is connected to a water collecting box 4 located below the filter plate 3, and a drainage pipe 5 is reserved on the water collecting box 4; a slag collection trough 6 is also arranged along the outside of the slag discharge port of the water filter box 2, and a slag collecting box 7 is installed at the discharge end of the slag collection trough 6.

[0023] Wastewater enters through the water inlet at the top of the filter tank 2 and undergoes preliminary filtration through filter plates 3, which are tilted toward the slag outlet. These plates effectively intercept large particles of sediment and impurities, forcing them to slide along the slope toward the slag outlet. The filtered water then flows through the plates 3 into the water collection tank 4 below, where it is discharged through a drain pipe 5. Simultaneously, a slag collection trough 6, located outside the slag outlet of the filter tank 2, collects the intercepted sediment and impurities, ultimately directing them to a slag collection tank 7 for centralized sediment treatment and discharge.

[0024] As an embodiment, the filter plates 3 are distributed in multiple steps along the slag discharge direction.

[0025] By designing the filter plates 3 as a multi-step distribution along the slag discharge direction, the filtration area can be increased. At the same time, the water flow is divided and merged multiple times during the filtration process, which helps to gradually deposit impurities such as sediment on each step, thereby improving filtration efficiency and accuracy. This design also effectively slows the water flow rate and reduces the risk of filter plate clogging.

[0026] As an embodiment, a grid-shaped drain rack 8 is further arranged at the connection between the water collecting box 4 and the water filtering box 2 to ensure smooth passage of clean water and avoid water accumulation inside the water collecting box.

[0027] Specifically, the inner cavity size of the water filter box 2 narrows from top to bottom, which helps to accelerate the water flow rate and facilitates collection.

[0028] As an embodiment, the main frame 1 is further provided with a vibration mechanism connected to the water filter box 2 .

[0029] Specifically, the vibration mechanism includes a plurality of vibration springs 9 installed between the main frame 1 and the water filter box 2, and a vibration motor 10 installed on the water filter box 2.

[0030] When the vibration motor 10 is activated, it generates periodic vibrations through mechanisms such as an internal eccentric rotor or electromagnetic force. This vibration is transmitted through the filter box 2 to the connected vibration spring 9, causing the spring to deform and release energy, thus generating continuous vibration waves. These vibration waves produce a strong vibration effect within the filter box 2, helping to loosen and remove impurities such as sediment accumulated on the filter plate 3, preventing clogging.

[0031] It should be noted that, in this article, the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise expressly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0033] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
