An anti-clogging filter head suitable for ozone catalytic systems

Abstract

This invention provides an anti-clogging filter head suitable for ozone catalytic systems, comprising a filter head body, with a water inlet pipe fixedly connected to the bottom of the filter head body. The water inlet pipe has a downward-opening water inlet channel, the top of which extends upward into the filter head body. A conical connecting groove is connected to the top of the water inlet channel. This design utilizes a streamlined flow-guiding design with a conical connecting groove to improve water flow uniformity, eliminate eddy current dead zones, and prevent particulate matter deposition. Simultaneously, the PVDF / PTFE material surface of the screw plug provides both physical barrier and chemical anti-adhesion effects for dual anti-clogging. This design employs check glass beads; when water enters the system, the check glass beads float, allowing water to flow through the outlet distribution channel into the filter head. When the system stops supplying water, the check glass beads fall, sealing the water distribution chamber opening and preventing water from flowing back into the ozone catalytic system's inlet chamber.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an anti-clogging filter head suitable for ozone catalytic systems. Background Technology

[0002] Ozone catalytic oxidation technology is widely used in the advanced treatment of industrial wastewater. In this process, wastewater and ozone are evenly distributed through a microporous filter head and react with the catalyst. However, existing filter heads have the following problems:

[0003] Easy to clog: Suspended solids, colloids, microorganisms, etc. in wastewater can easily adhere to the surface of the filter head, causing blockage of the water distribution gaps and affecting the stable operation of the system.

[0004] Difficult to clean: Traditional filter heads require frequent disassembly and cleaning, increasing maintenance costs.

[0005] The treated water volume is easily reduced, and the operating cost increases: blockage leads to uneven distribution of sewage and ozone, reducing the treated water volume. At the same time, some ozone does not participate in the reaction and is directly released, increasing the operating cost. Summary of the Invention

[0006] Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an anti-clogging filter head suitable for ozone catalytic systems, which can effectively prevent clogging, improve the operational stability of ozone catalytic systems, and solve the problems mentioned in the background art.

[0008] Technical solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging filter head suitable for ozone catalytic systems, comprising a filter head body, a water inlet pipe fixedly connected to the bottom of the filter head body, a downward-opening water inlet channel inside the water inlet pipe, the top of the water inlet channel extending upward into the filter head body, a conical cone-shaped connecting groove connected to the top of the water inlet channel, a water distribution chamber with an upward opening connected to the top of the cone-shaped connecting groove, a plurality of outward-opening water distribution channels connected to the inner wall of the water distribution chamber, the water distribution channels being inclined and opening downward, and the water distribution channels being arranged in a circular array.

[0010] Preferably, the filter head body has a hexagonal end at the top, which is milled flat into a hexagonal shape for fixing with a wrench.

[0011] Preferably, a screw plug is installed inside the hexagonal end, and the hexagonal end has internal threads to facilitate the installation and connection of the screw plug.

[0012] Preferably, a detachable check glass bead is installed inside the water distribution cavity, and the check glass bead is spherical.

[0013] Preferably, a detachable fixing flange nut is installed on the outer end face of the water inlet pipe, and the fixing flange nut serves as a sealing and protective element. Beneficial effects

[0014] This invention provides an anti-clogging filter head suitable for ozone catalytic systems. It offers the following advantages:

[0015] This solution uses a ring array of inclined water distribution channels with a precisely designed downward opening angle to utilize the gravity component of the water flow for self-flushing, resulting in a longer anti-clogging cycle compared to traditional straight-hole filter heads.

[0016] This solution employs a streamlined flow guide design with a conical connecting groove to improve water flow uniformity, eliminate eddy dead zones, and prevent particle deposition. Meanwhile, the PVDF / PTFE material surface of the screw plug achieves a dual anti-clogging effect of physical barrier and chemical anti-adhesion.

[0017] This solution uses check glass beads. When water enters the system, the check glass beads are floated by the water flow, allowing the water to enter the filter head through the outlet distribution channel. When the system stops, the check glass beads fall down and block the water distribution chamber opening, preventing water from flowing back into the ozone catalytic system inlet chamber.

Detailed Implementation

[0023] This utility model provides an anti-clogging filter head suitable for ozone catalytic systems, such as... Figure 1-4As shown, the filter head body 101 is included. A water inlet pipe 105 is fixedly connected to the bottom of the filter head body 101. A water inlet channel 108 with a downward opening is provided in the water inlet pipe 105. The top of the water inlet channel 108 extends upward into the filter head body 101. A conical cone head connecting groove 110 is connected to the top of the water inlet channel 108. A water distribution chamber 107 with an upward opening is connected to the top of the cone head connecting groove 110. A plurality of water distribution channels 102 with outward openings are connected to the inner wall of the water distribution chamber 107. The water distribution channels 102 are inclined and have downward openings. The positions of the water distribution channels 102 are arranged in a circular array.

[0024] It should be further noted that the outer end face of the water inlet pipe 105 is threaded.

[0025] Furthermore, the top of the filter head body 101 is provided with a hexagonal end 104, which is milled flat into a hexagonal head shape for fixing with a wrench.

[0026] Furthermore, a screw plug 103 is installed inside the hexagonal end 104, and the hexagonal end 104 is provided with internal threads to facilitate the installation and connection of the screw plug 103.

[0027] It should be further noted that the screw plug 103 is made of PVDF or PTFE.

[0028] Furthermore, a detachable check glass bead 109 is installed inside the water distribution cavity 107. The check glass bead 109 is spherical.

[0029] It is worth further explaining that the anti-backflow glass bead 109 floats when water is introduced and falls when water is stopped to prevent water from flowing back.

[0030] Furthermore, a detachable fixing flange nut 106 is installed on the outer end face of the water inlet pipe 105, which serves as a sealing and protective measure.

[0031] When using this solution, confirm that the thread specification of the outer end face of the water inlet pipe 105 matches the system pipe interface. Install a detachable fixing flange nut 106 on the outer end face of the water inlet pipe 105 as a sealing and protective component to prevent foreign objects from entering the inner cavity of the water inlet channel 108 during installation. Use a wrench to hold the hexagonal end 104 at the top of the filter head body 101 and screw the water inlet pipe 105 into the system pipe interface. Secure it through threaded connection to ensure the sealing of the water inlet pipe 105 and the pipe interface. At the same time, screw the plug 103 into the hexagonal end 104 and use the internal thread of the hexagonal end 104 for installation connection. The plug 103 plays a primary filtration role, intercepting large particulate impurities.

[0032] A removable check glass bead 109 is installed inside the water distribution chamber 107. It is confirmed that the check glass bead 109 can float freely inside the water distribution chamber 107. When water enters the system, the check glass bead 109 is floated by the water flow, allowing the water to enter the filter head through the outlet distribution channel 102. When the system stops, the check glass bead 109 falls down, blocking the opening of the water distribution chamber 107 and preventing water from flowing back into the ozone catalytic system. The water treatment capacity of a single filter head can be achieved by adjusting the diameter of the inlet channel 108 and the channel diameter and number of the outlet distribution channel 102.

[0033] Connect the tapered interface 110 at the top of the filter head's inlet channel 108 to the inlet of the ozone catalytic system to ensure a tight fit between the tapered sealing surfaces and prevent leakage.

[0034] During use, the water distribution channels 102 distributed in a ring array disperse the water flow and prevent blockage.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
