Abstract
Description
Technical Field
[0001] This utility model relates to the field of water filtration technology, and in particular to a biological leakage prevention device for filter bed effluent. Background Technology
[0002] Biofilms readily form on the porous media or filter media surfaces of activated carbon filters and sand filters. While biofilms help degrade organic matter, aging and detached biofilm fragments can become carriers for microorganisms in the effluent. Sand filters primarily remove suspended solids, with limited removal of dissolved substances and small particles. Activated carbon adsorbs organic matter, but its porous structure makes it a breeding ground for microorganisms.
[0003] In existing technologies, flat plate filters or automatic biological leakage filters are used at the effluent of the filter bed. Flat plate filters do not have a self-cleaning function and need to be manually removed periodically, which is inconvenient. Automatic biological leakage filters are expensive and inconvenient to maintain. Utility Model Content
[0004] The purpose of this invention is to provide a biological leakage prevention device for filter bed effluent, so as to alleviate the problems of existing flat plate filters requiring manual periodic removal and rinsing, and the high price and inconvenient maintenance of automatic biological leakage filters.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A bioleaking prevention device for filter bed effluent includes: a filter bed effluent pipe, an effluent channel, a bioleaking prevention filter assembly, a weir-post channel, and a clear water main channel. The filter bed effluent pipe is connected to the effluent channel, the weir-post channel is connected to both the effluent channel and the clear water main channel, and the bioleaking prevention filter assembly is disposed between the effluent channel and the weir-post channel. A flushing assembly is provided above the bioleaking prevention filter assembly, and a slag discharge assembly is provided below the bioleaking prevention filter assembly.
[0006] Furthermore, the filter outlet pipe is equipped with an automatic valve, which is used to control the opening and closing of the pipeline between the filter outlet pipe and the outlet channel.
[0007] Furthermore, the outlet of the water channel is equipped with an adjustable weir plate.
[0008] Furthermore, the bioleaking prevention filter assembly includes a bioleaking prevention filter and a sliding door groove. The bioleaking prevention filter is equipped with a hoisting structure, and the bioleaking prevention filter is installed in the sliding door groove through the hoisting structure.
[0009] Furthermore, the bioleaking prevention filter includes a filter screen and a support, with the filter screen mounted on the support.
[0010] Furthermore, the slag discharge assembly includes a slag discharge trough and a discharge pipe. The slag discharge trough is located at the bottom of the bioleaking prevention filter screen, and the slag discharge trough is connected to the discharge pipe.
[0011] Furthermore, the discharge pipe is equipped with a discharge valve, which is used to control the opening and closing of the pipeline between the discharge pipe and the drainage ditch.
[0012] Furthermore, the filter residue discharge trough is made of metal and is fixedly connected to the pre-embedded steel plate of the partition wall.
[0013] Furthermore, the flushing assembly includes a perforated flushing water pipe and a flushing pressure water pipe, the perforated flushing water pipe being positioned above the bioleaking prevention filter, and the flushing pressure water pipe being connected to the perforated flushing water pipe.
[0014] Furthermore, the flushing pressure water pipe is equipped with a flushing valve.
[0015] This utility model can bring at least the following beneficial effects: The present invention provides a bioleaking prevention device for filter effluent, comprising: a filter effluent pipe, an effluent channel, a bioleaking prevention filter assembly, a weir-followed channel, and a clear water main channel. The filter effluent pipe is connected to the effluent channel, and the weir-followed channel is connected to both the effluent channel and the clear water main channel. The bioleaking prevention filter assembly is disposed between the effluent channel and the weir-followed channel. A flushing assembly is disposed above the bioleaking prevention filter assembly, and a sludge discharge assembly is disposed below the bioleaking prevention filter assembly.
[0016] When a single-cell filter is operating normally, water flows sequentially through the filter's outlet pipe, outlet channel, and the bioleaking prevention filter assembly, entering the downstream channel and finally flowing into the main clear water channel. A filter typically has two or more cells, all entering the main clear water channel in the same manner. When the filter stops operating, the water level drops, and the flushing assembly begins flushing the bioleaking prevention filter assembly. Filter debris falls along the bioleaking prevention filter assembly to the debris discharge assembly, and finally drains into the nearest drainage ditch, completing the interception of biological filter debris. The flushing time and frequency can be adjusted appropriately based on the amount of biological filter debris in the effluent. After the bioleaking prevention filter assembly is cleaned, the filter resumes normal filtration.
[0017] The biological leakage prevention device used for filter bed effluent can ensure the safety and reliability of the water supply, is easy to flush, has a simple structure, low cost, and can generate significant economic benefits.

[0028] Example 1 Existing technologies use flat plate filters or automatic biological leakage filters at the effluent of the filter bed. Flat plate filters do not have a self-cleaning function and need to be manually removed periodically, which is inconvenient. Automatic biological leakage filters are expensive and inconvenient to maintain.
[0029] In view of this, this utility model embodiment provides a biological leakage prevention device for filter effluent, including: filter effluent pipe 100, effluent channel 200, biological leakage prevention filter assembly, weir channel 700 and clear water main channel 800. The filter effluent pipe 100 is connected to the effluent channel 200, the weir channel 700 is connected to both the effluent channel 200 and the clear water main channel 800, and the biological leakage prevention filter assembly is disposed between the effluent channel 200 and the weir channel 700. A flushing component is disposed above the biological leakage prevention filter assembly, and a sludge discharge component is disposed below the biological leakage prevention filter assembly.
[0030] When a single-cell filter is operating normally, water flows sequentially through the filter outlet pipe 100, the outlet channel 200, and the anti-biological leakage filter assembly, entering the downstream channel 700, and finally flowing into the main clear water channel 800. A filter typically has two or more cells, all entering the main clear water channel 800 in the same manner. When the filter stops operating, the water level drops, and the flushing assembly begins flushing the anti-biological leakage filter assembly. Filter debris falls along the anti-biological leakage filter assembly to the debris discharge assembly, and finally drains into the nearest drainage ditch, completing the interception of biological filter debris. The flushing time and frequency can be adjusted appropriately according to the amount of biological filter debris in the effluent. After the anti-biological leakage filter assembly is cleaned, the filter resumes normal filtration.
[0031] The biological leakage prevention device used for filter bed effluent can ensure the safety and reliability of the water supply, is easy to flush, has a simple structure, low cost, and can generate significant economic benefits.
[0032] In an optional embodiment, the filter outlet pipe 100 is equipped with an automatic valve 110, which is used to control the opening and closing of the pipeline between the filter outlet pipe 100 and the outlet channel 200.
[0033] Please see Figure 1 An automatic valve 110 is installed on the filter outlet pipe 100. The automatic valve 110 can be electric or pneumatic. The automatic valve 110 controls the flow of water between the filter outlet pipe 100 and the outlet channel 200.
[0034] In an optional embodiment, the outlet of the water outlet channel 200 is provided with an adjustable weir plate 210.
[0035] Please see Figure 2 The height of the adjustable weir plate 210 can be adjusted to ensure the consistency of the head loss of the inlet and outlet water in each filter cell, thus ensuring the filtration effect.
[0036] In an optional embodiment, the bioleaking prevention filter assembly includes a bioleaking prevention filter 300 and a slide rail door groove 400. The bioleaking prevention filter 300 is provided with a hoisting structure and is installed in the slide rail door groove 400 through the hoisting structure.
[0037] Please see Figure 1 and Figure 2 The installation angle of the bio-leakage prevention filter 300 is 60-90°. The hoisting structure can use a lifting ring or a handle. The bio-leakage prevention filter 300 is installed in the slide rail door groove 400 and is moved up and down along the slide rail door groove 400 by a chain connected to the lifting ring or handle for easy maintenance.
[0038] Furthermore, the bioleaking filter 300 includes a filter 310 and a support 320, with the filter 310 mounted on the support 320.
[0039] Please see Figure 3 The bioleaking filter 300 consists of a stainless steel or nylon filter 310 and a steel support frame 320. The filter 310 has a mesh size of 200.
[0040] In an optional embodiment, the slag discharge assembly includes a slag discharge trough 510 and a discharge pipe 520. The slag discharge trough 510 is disposed at the bottom of the bioleaking filter screen 300, and the slag discharge trough 510 is connected to the discharge pipe 520.
[0041] Please see Figure 1 A filter residue discharge trough 510 is installed after the adjustable weir plate 210. The filter residue discharge trough 510 has a certain slope and slopes towards the discharge pipe 520 to facilitate the filter residue from the filter residue discharge trough 510 into the discharge pipe 520. The filter residue discharge trough 510 is made of metal and is fixedly connected to the pre-embedded steel plate of the partition wall by welding.
[0042] In an optional embodiment, the discharge pipe 520 is provided with a discharge valve 521, which is used to control the opening and closing of the pipeline between the discharge pipe 520 and the drainage ditch.
[0043] Please see Figure 1 The discharge valve 521 is installed on the discharge pipe 520. The discharge valve 521 can control the opening and closing of the pipeline between the discharge pipe 520 and the drainage ditch, which facilitates the discharge of filter residue.
[0044] In an optional embodiment, the flushing assembly includes a perforated flushing water pipe 610 and a flushing pressure water pipe 620. The perforated flushing water pipe 610 is disposed above the bioleaking filter 300, and the flushing pressure water pipe 620 is connected to the perforated flushing water pipe 610.
[0045] Please see Figure 1The perforated flushing water pipe 610 flows downwards along the bioleaking prevention filter screen 300, allowing filter cake to slide down the filter screen 300 to the filter cake discharge trough 510 at the bottom. A flushing valve 621 is installed on the flushing pressure water pipe 620 to control the flow of flushing water. The perforated flushing water pipe 610 is located above the bioleaking prevention filter screen 300 and connected to the flushing pressure water pipe 620. The perforations of the perforated flushing water pipe 610 are 5-8 mm, staggered every 25 mm, and the openings face directly towards the bioleaking prevention filter screen 300.
[0046] The discharge valve 521 is both manual and electric, and is linked with the flushing valve 621, which is also both manual and electric. Based on operational experience, regular flushing and discharge are performed at a certain flushing frequency. Cleaning is divided into the following three types: During filter backwashing, the automatic valve 110 is closed, and the anti-biological leakage filter 300 is opened to start the flushing mode, ensuring thorough cleaning of the anti-biological leakage filter 300 and discharge of flushing water; During normal filter filtration, the flushing mode is opened at a certain flushing frequency based on operational experience; In case of emergency or filter maintenance, the filter inlet water and the automatic valve 111 are closed, and manual forced flushing is performed.
[0047] The following describes the four operating conditions of the biological leak prevention device in this embodiment.
[0048] Operating Condition 1: When a single-cell filter is operating normally, the automatic valve 110 opens, and the water flows through the outlet channel 200, the adjustable weir plate 210, and the biological leakage prevention filter screen 300, enters the post-weir channel 700, and then enters the clear water main channel 800 through the flow passage 900. A filter typically has two or more cells, all of which enter the clear water main channel 800 in the same way.
[0049] Operating Condition 2: When the filter tank stops working (e.g., during the backwashing stage), the automatic valve 110 closes, the water level drops, the discharge valve 521 and the flushing valve 621 open, and the perforated flushing water pipe 610 begins to flush the anti-biological leakage filter screen 300. The filter residue falls along the anti-biological leakage filter screen 300 into the filter residue discharge trough 510. The filter residue discharge trough 510 discharges the filter residue along the slope to the discharge pipe 520, and finally connects to the nearest drainage ditch, completing the interception of biological filter residue.
[0050] Operating Condition 3: In an emergency, when the single-cell filter is working normally, the automatic valve 110 is opened, and the water level at the outlet and the water level behind the weir both exceed the normal values. At this time, the discharge valve 521 and the flushing valve 621 are opened, and the perforated flushing water pipe 610 begins to flush the anti-biological leakage filter screen 300. The filter residue falls along the anti-biological leakage filter screen 300 into the filter residue discharge trough 510. The filter residue discharge trough 510 discharges the filter residue along the slope to the discharge pipe 520, and finally connects to the nearest drainage ditch to complete the interception of biological filter residue.
[0051] Operating Condition 4: After the anti-biological leakage filter 300 is cleaned, close the discharge valve 521 and the flushing valve 621, and open the automatic valve 110 to start normal filtration.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
