Description

Technical Field

[0001] This utility model mainly relates to the field of wastewater treatment technology, specifically a filtration structure for a filtration tank. Background Technology

[0002] With the acceleration of industrialization and urbanization, the importance of wastewater treatment has become increasingly prominent. In the field of wastewater treatment technology, the filter tank, as one of the core devices for achieving wastewater purification, directly determines the treatment efficiency and quality of wastewater through its internal filtration structure. The filter basket, as a key component in the filter tank for intercepting solid impurities and suspended solids in wastewater, is widely used in various types of filter tanks. In traditional filter baskets, impurities in the wastewater continuously accumulate inside during actual use. As the usage time increases, the pores of the filter basket gradually become clogged, leading to a significant decrease in filtration efficiency. In severe cases, this can even affect the normal operation of the entire filtration tank. Staff need to periodically interrupt the filtration process, and the interruption time is relatively long. The usual procedure is to remove the filter basket from the filtration tank for manual cleaning, and then reinstall the filter basket in its original position before continuing the subsequent filtration work. The frequent cleaning process not only consumes a lot of time and manpower, but the long interruption of filtration work also affects the overall wastewater treatment efficiency. Utility Model Content

[0003] This utility model provides a solution that addresses the problem of overly simplistic existing solutions. It offers a significantly different approach by providing a filtration structure for a filtration tank. This solution addresses the issue mentioned in the background section where traditional filter baskets experience pore blockage due to continuous accumulation of wastewater impurities, leading to decreased filtration efficiency. To resolve this blockage, staff must periodically interrupt filtration and manually remove the baskets for cleaning. This process is not only time-consuming and labor-intensive, but frequent and prolonged interruptions also negatively impact the overall efficiency of wastewater treatment.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A filtration structure for a filtration tank includes a mounting frame, a filtration assembly is disposed on the inner wall of the mounting frame, a vibration motor is disposed on the outer wall of the filtration assembly, and a valve is disposed at the bottom of the filtration assembly.

[0005] The filtration assembly includes a filter basket for initial filtration of wastewater.

[0006] More preferably, the outer wall of the filter basket is provided with a mounting ring near the top, and two symmetrically distributed handles are installed on the top of the mounting ring.

[0007] More preferably, the upper part of the filter basket is designed as a tubular structure, while the lower part adopts a frustum-shaped design that is wider at the top and narrower at the bottom. Several filter holes are evenly distributed around the outer wall to guide the sediment entering the filter basket to accumulate at the bottom along the inclined wall.

[0008] More preferably, the upper and lower outer peripheries of the filter basket are each surrounded by a number of reinforcing ribs, and the reinforcing ribs are distributed in a ring at equal intervals along the circumference to improve the structural rigidity of the upper and lower parts of the filter basket.

[0009] More preferably, the outlet end of the valve is connected to the inlet end of the sludge pump via a connecting pipe, which is used to draw out the impurities deposited in the filter basket by the negative pressure generated by the sludge pump.

[0010] More preferably, the top of the mounting frame has a mounting hole with an inner diameter larger than the outer diameter of the upper part of the filter basket, the top of the mounting ring has a plurality of connecting holes arranged in a ring, and the top of the mounting frame has a corresponding connecting hole that matches the position of the connecting hole on the top of the mounting ring. The mounting ring and the mounting frame are fixedly connected by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This filtration structure, through a filter assembly, a vibrating motor, and a sludge pump, features a unique upper tubular structure and a lower frustum-shaped design (wider at the top and narrower at the bottom). Combined with evenly distributed circumferential filter holes, it performs initial filtration of wastewater. The frustum-shaped inclined wall utilizes gravity to guide sediment to naturally slide and accumulate, reducing sediment adhesion to the filter basket wall and lowering the risk of clogging. The high-frequency vibration generated by the vibrating motor effectively breaks the adhesion between the sediment and the filter basket wall, causing the sediment to quickly slide to the bottom. When a certain amount of sediment accumulates at the bottom of the filter basket, the sludge pump system, consisting of valves, a sludge pump, and connecting pipes, uses negative pressure suction to quickly remove and discharge the sediment without prolonged interruption of filtration. Compared to traditional filter baskets, this filtration structure reduces the frequency and time of manual cleaning and maintenance, thus improving treatment efficiency.

[0015] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0016] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0017] Please refer to the appendix carefully. Figures 1-3 A filter structure for a filter tank includes a mounting frame 1, a filter assembly 2 is provided on the inner wall of the mounting frame 1, a vibration motor 3 (which may be a waterproof electromagnetic vibration motor or a waterproof permanent magnet vibration motor) is provided on the outer wall of the filter assembly 2, and a valve 4 (which may be a waterproof electric butterfly valve or a waterproof electric knife gate valve) is installed at the bottom of the filter assembly 2.

[0018] The filter assembly 2 includes a filter basket 201 for primary filtration of wastewater.

[0019] In this embodiment, as Figure 3 As shown, an installation ring 202 is fixed on the outer wall of the filter basket 201 near the top. Two symmetrically distributed handles 203 are installed on the top of the installation ring 202. When moving, installing or removing the filter basket 201, the handles 203 on both sides can be held with both hands respectively, which facilitates the movement, installation or removal of the filter basket 201.

[0020] In this embodiment, as Figure 3 As shown, the upper part of the filter basket 201 is designed as a tubular structure, while the lower part adopts a frustum-shaped design that is wider at the top and narrower at the bottom. Several filter holes are evenly distributed around its outer wall. The frustum-shaped design with a wider top and narrower bottom, combined with the evenly distributed filter holes, increases the filtration area and accelerates the fluid filtration speed. The frustum-shaped inclined wall at the bottom of the filter basket 201 uses the principle of gravity to guide the sediment to slide naturally down the wall and accumulate at the bottom, preventing the sediment from accumulating inside the filter basket 201 and reducing the risk of clogging.

[0021] In this embodiment, as Figure 1 ,Figure 2 and Figure 3 As shown, the upper and lower outer peripheries of the filter basket 201 are surrounded by several reinforcing ribs, which are distributed in a ring at equal intervals along the circumference to improve the structural rigidity of the upper and lower parts of the filter basket 201. The vibration motor 3 is symmetrically installed on the lower outer side of the filter basket 201. The high-frequency vibration generated by the vibration motor 3 during operation can break the adsorption force between the sediment and the wall of the filter basket 201, causing the sediment to slide quickly down the frustum-shaped inclined wall to the bottom. During the vibration process, the reinforcing ribs ensure the structural stability of the filter basket 201 and avoid deformation or damage caused by vibration.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, valve 4 is installed at the bottom of filter basket 201. The outlet end of valve 4 is connected to the inlet end of sludge pump 6 through connecting pipe 5. With the help of the negative pressure generated by sludge pump 6, the impurities deposited in filter basket 201 can be sucked out. Compared with manual cleaning, this automated impurity discharge method improves processing efficiency, reduces manual intervention, and reduces labor intensity.

[0023] In this embodiment, as Figure 1 and Figure 3 As shown, the top of the mounting frame 1 has a mounting hole with an inner diameter larger than the outer diameter of the upper part of the filter basket 201, so that the filter basket 201 can pass through the mounting hole for installation. The top of the mounting ring 202 has several ring-shaped connecting holes, and the top of the mounting frame 1 has corresponding mounting holes that match the positions of the connecting holes on the top of the mounting ring 202. The mounting ring 202 and the mounting frame 1 are fixedly connected by bolts passing through the connecting holes on it. An annular vibration isolation pad is provided between the mounting frame 1 and the mounting ring 202 to reduce vibration transmission and improve the stability of the connection. The filter assembly 2 and the mounting frame 1 are detachable for easy maintenance. When the vibration motor 3 is running, the annular vibration isolation pad between the mounting frame 1 and the mounting ring 202 can block the transmission of vibration to the mounting frame 1, reduce the noise caused by vibration, and also buffer the impact force between the filter basket 201 and the mounting frame 1 to a certain extent, enhancing the stability of the connection.

[0024] The specific operating procedure of this utility is as follows: First, the filter is securely installed on the filter tank through the mounting holes on the mounting bracket 1, or installed above the filter tank with the support bracket (so that the filter components do not come into contact with the liquid surface). After the sewage treatment process is started, the sewage flows into the filter basket 201 through the upper sewage outlet. The tubular structure at the top of the filter basket 201 and its lower frustum-shaped design (wider at the top and narrower at the bottom) combined with the circumferentially evenly distributed filter holes achieve the initial filtration of sewage. The frustum-shaped inclined wall at the bottom of the filter basket 201 uses the principle of gravity to guide the sediment to slide naturally down the wall and collect at the bottom, where it is concentrated.

[0025] When the vibration motor 3 (which can be started intermittently through the control system as needed, such as vibrating for 5 minutes every 30 minutes, and can be linked with the sludge pump to start and stop to prevent blockage when removing sediment) is started, the high-frequency vibration it generates breaks the adsorption force between the sediment and the wall of the filter basket 201, causing the sediment to slide quickly down the frustum-shaped inclined wall to the bottom. At the same time, the reinforcing ribs set on the upper and lower outer periphery of the filter basket 201 ensure the structural stability of the filter basket 201 during vibration, avoiding deformation or damage caused by vibration.

[0026] Once the sediment at the bottom of the filter basket 201 has accumulated to a certain amount, stop discharging wastewater, open valve 4, and start the sludge pump 6. The sludge pump 6 uses the principle of negative pressure suction to quickly remove the sediment and impurities from the filter basket 201 through the connecting pipe 5. After the impurities are removed, close valve 4 and continue discharging wastewater for filtration.

[0027] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
