Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a filter element for wastewater treatment. Background Technology

[0002] Wastewater refers to the total amount of water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other non-use water such as initial rainwater runoff into drainage pipes and ditches. Generally, it refers to water that cannot be recycled after certain technical treatment or water that is too difficult to purify to meet certain standards after primary pollution.

[0003] Filtering impurities in wastewater is an important step in the wastewater treatment process. Filtering wastewater requires filter cartridges. However, most current filter cartridges use a single piece of filter media that restricts the size of particles to pass through. Impurities of different sizes that do not meet the requirements accumulate in one place, which can cause blockage in a short time and affect the normal flow of water in the filtration channel. Utility Model Content

[0004] The purpose of this invention is to provide a filter element for wastewater treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A filter element for wastewater treatment, comprising: The filter element body includes a mesh cylinder, an inner cylinder is sleeved inside the mesh cylinder, a plurality of conical filter membranes are fixedly installed between the mesh cylinder and the inner cylinder, and a plurality of filter blocks are clamped inside the inner cylinder; The top cover includes a top sleeve, which is fixedly installed on the upper edge of the mesh cylinder; The bottom cover includes a bottom sleeve, which is fixedly installed on the bottom edge of the mesh cylinder.

[0006] Furthermore, the inner wall of the mesh cylinder is fixedly equipped with several limiting clips, and the lower edge of the mesh cylinder is provided with water inlets.

[0007] Furthermore, a top sealing plate is fixedly installed on the upper side of the inner cylinder, and a water inlet is interlaced inside the top sealing plate. A top retainer is screwed into the gap between the top sleeve and the top sealing plate.

[0008] Furthermore, a swivel opening is provided in the middle of the bottom sleeve, and the upper edge of the swivel opening is fixedly connected to the lower edge of the inner cylinder.

[0009] Furthermore, a bottom bracket is fixedly fitted onto the outer surface of the bottom sleeve, and the outer surface of the bottom bracket is provided with water outlet channels arranged in a ring at equal angles.

[0010] Furthermore, the screw opening is screwed into the bottom sealing plate, and a screw handle is provided at the bottom of the bottom sealing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: First, the entire filter element is packed into the wastewater treatment equipment. The water distribution line enters the inner cylinder through the top cover, passes through each filter block for filtration, and then flows into the gap between the screen cylinder and the inner cylinder for filtration by each conical filter membrane. Finally, it is discharged from the mesh of the screen cylinder. The size of the gaps inside the filter blocks gradually decreases from top to bottom. At the same time, the molecular size that each conical filter membrane can filter also gradually decreases from the inside to the outside. This allows for the batch and graded interception of impurity particles of different sizes. Compared with single-stage monolithic filter media, this avoids impurities accumulating too much in one place in a short period of time, which would affect the flow rate. The graded and batch interception can greatly slow down the rate at which this impact increases, improve the service life of the overall device, and extend the replacement cycle.

[0012] The top bracket can be removed to expose the gap between the screen cylinder and the inner cylinder. The internal space of the inner cylinder can be exposed by unscrewing the bottom plate, which facilitates the disassembly and assembly of the conical filter membrane and filter block during production and recycling.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4In this embodiment of the utility model, a filter element for wastewater treatment includes a filter element body 1, a top cover 2 and a bottom cover 3, a mesh cylinder 101, an inner cylinder 102 sleeved inside the mesh cylinder 101, a plurality of conical filter membranes 103 fixedly installed between the mesh cylinder 101 and the inner cylinder 102, and a plurality of filter blocks 105 clamped inside the inner cylinder 102; a top sleeve 201 fixedly installed on the upper edge of the mesh cylinder 101; and a bottom sleeve 301 fixedly installed on the bottom edge of the mesh cylinder 101.

[0017] Specifically, the entire filter element is first packed into the wastewater treatment equipment. The water distribution line enters the inner cylinder 102 through the top cover 2, and is filtered by each filter block 105. Then, it is filtered by each conical filter membrane 103 through the gap between the mesh cylinder 101 and the inner cylinder 102. Finally, it is discharged from the mesh of the mesh cylinder 101. The size of the gaps inside the filter blocks 105 gradually decreases from top to bottom. At the same time, the molecular size that each conical filter membrane 103 can filter also gradually decreases from the inside to the outside. This can intercept impurity particles of different sizes in batches and grades. Compared with single-stage monolithic filter media, it avoids impurities from accumulating too much in one place in a short period of time, which affects the flow rate. Graded and batch interception can greatly slow down the rate at which this impact increases, improve the service life of the overall device, and extend the replacement cycle. Example

[0018] like Figure 1-3 As shown, in this embodiment, a plurality of limiting clips 104 are fixedly installed on the inner wall of the mesh cylinder 101, and a water inlet 106 is inserted through the lower edge of the mesh cylinder 101; a top plate 202 is fixedly installed on the upper side of the inner cylinder 102, and a water inlet 203 is inserted through the inside of the top plate 202; a top bracket 204 is screwed into the gap between the top sleeve 201 and the top plate 202.

[0019] In this embodiment, the water inlet 203 is connected to the water inlet pipe. The water inside the inner cylinder 102 enters the gap between the mesh cylinder 101 and the inner cylinder 102 through the water outlet 106. At the same time, each filter block 105 is fitted into the gap of each limiting edge 104, and the limiting edge 104 supports and limits the filter block 105. Example

[0020] Based on Example 1, in order to compensate for the fact that the filter element structure in Example 1 is a fully encapsulated structure, the only way to recycle and disassemble the used filter element is by force.

[0021] like Figure 2-4As shown, in this embodiment, a swivel opening 304 is inserted through the middle of the bottom sleeve 301, and the upper edge of the swivel opening 304 is fixedly connected to the lower edge of the inner cylinder 102; a bottom retainer 302 is fixedly sleeved on the outer surface of the bottom sleeve 301, and water outlet channels 303 are arranged in a ring at equal angles on the outer surface of the bottom retainer 302; the swivel opening 304 is screwed into the bottom sealing plate 305, and a handle 306 is provided at the bottom of the bottom sealing plate 305.

[0022] In practice, the top bracket 204 can be removed to expose the gap between the screen cylinder 101 and the inner cylinder 102. The internal space of the inner cylinder 102 can be exposed by unscrewing the bottom plate 305, which facilitates the disassembly and assembly of the conical filter membrane 103 and the filter block 105 during production and recycling.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
