Description

Technical Field

[0001] The utility model belongs to the field of sewage filtration, and specifically relates to a novel sewage filter net. Background Art

[0002] A sewage filter is a device used to filter impurities in sewage. It is usually composed of a series of tiny pores and can effectively separate solid particles, grease, organic matter and other substances in sewage to purify the water quality.

[0003] Sewage filter nets are widely used in sewage treatment plants, industrial production, agricultural irrigation and other fields. In sewage treatment plants, sewage filter nets are often used in the preliminary filtration process, which can effectively remove large particles of impurities in sewage and protect subsequent treatment equipment from damage.

[0004] However, the cleaning and maintenance costs of the sewage filter are high during its application, and the filter needs to be cleaned and replaced regularly. The existing sewage filter is provided with a diversion net. When the sewage first enters the diversion block, the sewage will first pass through the outer surface of the diversion net. The diversion net can filter most of the larger particles of debris and substances in the sewage, and the large particles of debris and substances in the sewage are filtered and retained on the top of the diversion net. By tilting the diversion net downward from the top of the filter plate to the top of the guide plate, gravity and attraction are used to discharge the debris to the side of the discharge pipe.

[0005] However, in actual use, the existing sewage infiltration net is not effective in treating high-concentration sewage, which can easily lead to blockage and poor operation of the infiltration net. The infiltration net needs to be replaced and flushed separately, and the infiltration efficiency is low. When treating large amounts of sewage, there is often insufficient processing capacity, which cannot meet actual needs.

[0006] In summary, a new sewage infiltration net is urgently needed to solve the problems of low infiltration efficiency and inconvenient cleaning of the existing sewage infiltration net. Utility Model Content

[0007] The embodiment of the utility model provides a novel sewage filter net, aiming to solve the problems of low infiltration efficiency and inconvenient cleaning of the existing sewage infiltration net.

[0008] The utility model embodiment is achieved in this way:

[0009] A novel sewage filter, comprising:

[0010] The first filter screen and the third filter screen are fixedly connected by a rotating shaft, and the first filter screen and the third filter screen can rotate freely around the rotating shaft;

[0011] A second filter screen is disposed between the first filter screen and the third filter screen;

[0012] Among them, a cavity is formed in the middle after the first filter screen and the third filter screen are combined, and the second filter screen is fixed in the cavity by embedding.

[0013] Furthermore, the first filter screen and the third filter screen are provided with connecting protrusions at both ends of a side close to the second filter screen.

[0014] Furthermore, two ends of the first filter screen and the third filter screen are provided with inserts.

[0015] Furthermore, grooves are provided at both ends of the second filter screen.

[0016] Furthermore, the second filter screen is movably connected to the cavity.

[0017] The beneficial effects achieved by the utility model are:

[0018] The utility model can effectively reduce looseness and misalignment during the assembly process by providing a rotating shaft between the first filter screen and the third filter screen, thereby ensuring the stability and reliability of the entire filtration system; secondly, the first filter screen and the third filter screen are combined to form a cavity, and the second filter screen is fixed in the cavity by inlaying, so that the second filter screen and the cavity are closer, effectively preventing impurities and particulate matter from penetrating into the gap, and can also improve the filtering effect and performance, reduce maintenance costs, increase sealing, and facilitate update.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In the utility model, the first filter screen and the third filter screen are fixedly connected via a rotating shaft, which can effectively reduce looseness and misalignment during the assembly process and ensure the stability and reliability of the entire filtering system.

[0031] Secondly, the inlay method can form a tighter connection between the second filter and the cavity, effectively preventing impurities and particulate matter from penetrating into the gap, thereby improving the filtering effect and performance. The second filter is fixed in the cavity by inlaying, which can not only improve the stability and reliability of the filtration system, but also improve the filtering effect and performance, reduce maintenance costs, increase sealing, and facilitate replacement.

[0032] Embodiment 1

[0033] Reference Figure 1 In the embodiment of the utility model, the embodiment provides a novel sewage filter 100, including: a first filter 110, a third filter 130, the first filter 110 and the third filter 130 are fixedly connected by a rotating shaft, and the first filter 110 and the third filter 130 can rotate freely around the rotating shaft;

[0034] The second filter 120 is disposed between the first filter 110 and the third filter 130;

[0035] Among them, a cavity is formed in the middle after the first filter screen 110 and the third filter screen 130 are combined, and the second filter screen 120 is fixed in the cavity by embedding.

[0036] In this embodiment, the sewage filter is a device for filtering impurities and solid particles in sewage. The sewage first passes through the filter, and larger particles and impurities are intercepted on the net, while relatively smaller particles are discharged through the mesh. In addition to filtering solid particles, the sewage filter can also be used to remove organic matter and microorganisms in water. By adjusting the material and pore size of the filter, different types of sewage can be treated. At the same time, the sewage filter can also reduce the burden in the subsequent treatment process and improve the overall treatment efficiency.

[0037] Specifically, see Figure 1In this embodiment, the sewage filter includes a first filter 110, and the first filter 110 is used to filter large particles of impurities entering the sewage circulation system to protect the normal operation of subsequent equipment.

[0038] The first filter screen 110 is usually made of a grid-shaped or mesh-shaped material, and can effectively filter out impurities in the water. By providing the first filter screen 110, not only the service life of the equipment can be extended, but also the water quality treatment effect can be improved.

[0039] The sewage filter net also includes a third filter net 130, which can effectively prevent the passage of tiny particles and microorganisms.

[0040] The first filter 110 and the third filter 130 can be fixedly connected by a rotating shaft, and the first filter 110 and the third filter 130 can also be connected by a hinge. The specific connection method of the first filter 110 and the third filter 130 can be selected according to actual needs; it should be noted that the first filter 110 and the third filter 130 can rotate freely around the rotating shaft after being connected, that is, the angle between the first filter 110 and the third filter 130 can be 0°-180°. When the first filter 110 and the third filter 130 are installed on the filter table, the angle between the first filter 110 and the third filter 130 is 0°, and the two are in a folded state. When the first filter 110 and the third filter 130 are cleaned, the angle between the first filter 110 and the third filter 130 is 180°, which is convenient for cleaning the first filter 110 and the third filter 130.

[0041] Specifically, see Figure 1 In this embodiment, the novel sewage filter 100 also includes a second filter 120, which is used to remove smaller particles that cannot be filtered out by the first filter 110. Certain microorganisms can also be applied on the second filter 120 to allow the sewage to undergo a preliminary biological reaction and allow the organisms to be more evenly mixed into the sewage.

[0042] The second filter 120 is arranged between the first filter 110 and the third filter 130. The second filter 120 can be fixed between the first filter 110 and the third filter 130 by inlaying. The second filter 120 can also be fixed between the first filter 110 and the third filter 130 by extrusion. The specific connection method of the second filter 120 can be selected according to actual needs.

[0043] It should be noted that after the first filter 110 and the third filter 130 are combined, a certain cavity may be generated between the first filter 110 and the third filter 130, and the shape of the cavity may complement the shape of the second filter 120, and the second filter 120 may be embedded in the cavity.

[0044] Based on the above structure, when the new sewage filter 100 is installed, the first filter 110 and the third filter 130 are fixedly connected by inlaying, and then the first filter 110 and the third filter 130 are merged together to form a certain cavity between the first filter 110 and the second filter 120, and then the second filter 120 is inlaid in the cavity. When the filter is blocked, the current second filter 120 is pulled out and the prepared second filter 120 is inlaid in the cavity.

[0045] The first filter screen 110 and the third filter screen 130 are fixedly connected via a rotating shaft, which can effectively reduce looseness and misalignment during the assembly process and ensure the stability and reliability of the entire filtering system.

[0046] Secondly, the inlay method can form a tighter connection between the second filter screen 120 and the cavity, effectively preventing impurities and particulate matter from penetrating into the gap, thereby improving the filtering effect and performance. The second filter screen 120 is fixed in the cavity by inlaying, which can not only improve the stability and reliability of the filtration system, but also improve the filtering effect and performance, reduce maintenance costs, increase sealing, and facilitate replacement.

[0047] Embodiment 2

[0048] See also Figure 4 and Figure 5 In the embodiment of the utility model, connecting protrusions 111 are provided at both ends of the first filter screen 110 and the third filter screen 130 close to the second filter screen 120 .

[0049] In this embodiment, connecting protrusions 111 are provided at both ends of the first filter 110 and the third filter 130 on one side close to the second filter 120 . When the second filter 120 is connected to the first filter 110 and the third filter 130 respectively, it is embedded and connected to the second filter 120 through the protrusions 111 .

[0050] Specifically, the shape of the protrusion 111 can be an I-shape, a cylinder, or a V-shape, and the specific shape can be selected according to actual needs.

[0051] Connecting protrusions 111 are provided at both ends of the first filter 110 and the third filter 130 near the second filter 120 to enhance the connection stability between the filters and effectively strengthen the connection between the filters to prevent loosening or falling off during use.

[0052] Embodiment 3

[0053] See also Figure 4 and Figure 5 In the embodiment of the utility model, insert blocks 112 are provided at both ends of the first filter screen 110 and the third filter screen 130 .

[0054] In this embodiment, blocks 112 are provided at both ends of the first filter screen 110 and the third filter screen 130. The blocks 112 are provided at both ends of the first filter screen 110 and the third filter screen 130 to facilitate fixing them at both ends of the filter tank. The shape of the blocks 112 can be I-shaped or cylindrical, and the specific shape can be selected according to actual needs.

[0055] The stability of the filter screen can be enhanced by providing the insert block 112. The insert block 112 can increase the structural strength of the filter screen, prevent deformation or damage during water flow, extend the service life of the filter screen, reduce the frequency of replacement and maintenance, and save maintenance costs.

[0056] See also Figure 2 and Figure 3 In the embodiment of the utility model, grooves 121 are provided at both ends of the second filter screen 120 .

[0057] In this embodiment, grooves 121 are provided at both ends of the second filter 120, and the shape of the groove 121 can be complementary to the shape of the protrusion 111. When the second filter 120 is connected to the first filter 110 and the third filter 130, the protrusions 111 of the first filter 110 and the third filter 130 are embedded in the grooves 121 of the second filter 120.

[0058] By providing the grooves 121 at both ends of the filter, the position of the filter can be effectively fixed to prevent it from loosening or shifting during use. The grooves 121 can effectively fix the position of the filter, making it easier to disassemble and clean, thereby reducing the time and cost of cleaning and maintenance.

[0059] Embodiment 5

[0060] See also Figure 1 In the embodiment of the utility model, the second filter screen 120 is movably connected to the cavity.

[0061] In this embodiment, it needs to be explained that the second filter screen 120 is movably connected to the cavity. The second filter screen 120 can be fixed at any position of the cavity relative to the cavity, and can also be detached from the cavity. When particles are concentrated at the upper end of the sewage, the second filter screen 120 can be fixed at the upper end of the cavity. When the second filter screen 120 needs to be replaced, the filter screen can be detached from the cavity.

[0062] The second filter screen 120 and the cavity are movably connected, so that the sewage filtering can be more reasonable and the sewage filtering efficiency can be increased. Meanwhile, the filter screen can be easily replaced and the labor intensity can be reduced.
