Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, and in particular to a centrifugal filtration structure for Fenton reaction. Background Technology

[0002] In the wastewater treatment process using the Fenton process, the wastewater contains a large number of solid particles, reaction precipitates, and other impurities. Therefore, the pumps used in the treatment equipment need to be equipped with filtration devices to prevent internal blockage or wear. In existing technologies, filtration devices generally adopt a mesh structure, which is directly installed at the inlet. Although this achieves basic filtration, impurities easily accumulate on the surface of the mesh structure. Once excessive accumulation occurs, it will directly block the inlet, causing the pump to cease operation.

[0003] Chinese utility model patent application number 202123358678.1 discloses a waste residue filtration device for drilling waste fluid treatment. This patent features a filter plate installed at the inlet of the water inlet pipe. Although the filter plate can be raised and emptied after accumulating impurities, its location at the inlet of the water inlet means that its permeability to waste fluid gradually decreases as impurities accumulate. This leads to a continuous decrease in the flow rate of the water inlet pipe, significantly impacting the efficiency of waste fluid collection. Consequently, subsequent waste fluid treatment equipment suffers a decline in treatment efficiency due to insufficient waste fluid intake. Utility Model Content

[0013] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0014] Example 1: like Figure 1-3 As shown: This utility model provides a centrifugal filtration structure for Fenton reaction, including a filter cylinder 1, a drive shaft 2, a drive device 3, and several fan blades 4; the filter cylinder 1 is a hollow cylindrical structure; an outlet 11 is provided at the center of the top of the filter cylinder 1; an inlet 12 is provided on the circumferential side of the filter cylinder 1; the drive shaft 2 is arranged inside the filter cylinder 1 along the axis of the filter cylinder 1, and the bottom end of the drive shaft 2 passes through the bottom of the filter cylinder 1 and is connected to the drive end of the drive device 3; several fan blades 4 are arranged sequentially in a circumferential direction inside the filter cylinder 1 along the circumferential side of the filter cylinder 1; the fan blades 4 are connected to the drive shaft 2; the drive device 3 drives the several fan blades 4 to rotate along the circumferential direction of the filter cylinder 1 through the drive shaft 2.

[0015] When the centrifugal filtration structure for the Fenton reaction provided by this utility model is in operation, the outlet 11 needs to be sealed and connected to the inlet of the pump body, and the inlet 12 needs to be sealed and connected to the waste liquid tank. Under the negative pressure of the pump body, the waste liquid containing impurities in the waste liquid tank enters the filter cylinder 1 from the inlet 12. The drive device 3 rotates at the central axis inside the filter cylinder 1 through the drive shaft 2, and the drive shaft 2 is connected to the fan blades 4, which in turn drive several fan blades 4 to rotate circumferentially in the filter cylinder 1. When the fan blades 4 rotate, they will drive the waste liquid containing impurities in the filter cylinder 1 to rotate together. During the circular motion of the waste liquid, centrifugal force is generated due to the inertia of the waste liquid itself. Under the centrifugal action, the larger impurities in the waste liquid move to the outer ring side inside the filter cylinder 1, and the impurity content is lower the closer the waste liquid is to the central axis. After centrifugation, the impurity content of the waste liquid at the upper part of the central axis is reduced to the minimum and discharged from the outlet 11.

[0016] This invention provides a centrifugal filtration structure for the Fenton reaction. Waste liquid containing impurities is introduced into a filter cylinder 1, where it undergoes circular motion driven by fan blades 4, generating centrifugal force to separate impurities to the outer ring inside the filter cylinder 1, thus filtering the waste liquid. The waste liquid is then discharged from the center. This design effectively prevents impurities from clogging the waste liquid outlet during filtration, and the impurities accumulated inside the filter cylinder 1 are easier to clean because they do not clog the filter screen.

[0017] The outlet 11 is located at the top of the filter cylinder 1. While the waste liquid is subjected to horizontal centrifugal force to filter impurities, the impurities are also deposited under gravity, minimizing the impurity content of the upper layer of waste liquid near the central axis. Since upward discharge of waste liquid requires overcoming gravity, and the negative pressure provided by the pump is limited, in a preferred embodiment, to facilitate upward flow of the waste liquid, the fan blade 4 has a plate structure; the fan blade 4 is tilted backward along its rotation direction; and the angle between the thrust surface of the fan blade 4 and the tangential direction of its rotation is acute.

[0018] In the preferred embodiment described above, the fan blades 4, which are tilted backward in the direction of rotation, can generate an upward component force on the waste liquid during the horizontal circular motion, thereby helping to push the waste liquid upward and making it easier for the waste liquid to be discharged from the outlet 11 at the top of the filter cartridge 1.

[0019] In a preferred embodiment, the thrust surface of the fan blade 4 is concave. The concave fan blade 4 can guide the waste liquid to flow smoothly along its surface, which can reduce turbulence and resistance compared to a flat surface, and can improve energy utilization. In addition, the waste liquid will form a local high-pressure zone in the concave area of ​​the fan blade 4, which can push the waste liquid to move at a higher circumferential speed. Therefore, the impurities in the waste liquid can be subjected to greater centrifugal force, thereby improving the separation effect of impurities.

[0020] In a preferred embodiment, the propulsion surface of the fan blade 4 is provided with a plurality of guide ribs 5; the plurality of guide ribs 5 are arranged sequentially along the width direction of the fan blade 4. The guide ribs 5 can guide the waste liquid, causing the waste liquid to flow along a preset path, reducing turbulence, making the flow of waste liquid more orderly, preventing separated impurities from being re-entrained into the central area, and ensuring the stability of separated impurities.

[0021] Since the impurities separated by filtration accumulate inside the filter cylinder 1, in a preferred embodiment to reduce the cleaning frequency of the filter cylinder 1, a storage area is formed in the space between the inner circumferential wall of the filter cylinder 1 and the fan blade 4; the storage area is distributed along the circumference of the filter cylinder 1; several baffle plates 6 are arranged circumferentially on the inner circumferential wall of the filter cylinder 1; the baffle plates 6 are arranged along the height direction of the filter cylinder 1, and the plate surface of the baffle plates 6 is perpendicular to the rotation tangent direction of the fan blade 4. Because the waste liquid continuously moves in a circular motion, centrifugal force is continuously generated, so the impurities accumulated in the outer ring inside the filter cylinder 1 are continuously subjected to pressure. To prevent the separated impurities from being washed away again by the waste liquid, multiple baffle plates 6 are arranged in the circumferential direction of the storage area. The baffle plates 6 can slow down the waste liquid in the outer ring, which is beneficial to the deposition of impurities.
