Description

Technical Field

[0001] This utility model relates to the field of fiber filtration technology, specifically to a white water fiber filtration device. Background Technology

[0002] The production of nonwoven fabrics typically generates a large amount of wastewater containing fibers, known as white water. Directly discharging this white water wastes fibers and pollutes the environment, so it is necessary to filter out the fibers from the white water.

[0003] In the prior art, a utility model with publication number "CN 213506282 U" discloses a white water fiber filtration device, including a tank, a separation cylinder, a turbulence section, a filtration section, an inlet pipe, and an outlet pipe. The separation cylinder is coaxially arranged inside the tank, dividing the tank into a first chamber and a second chamber. The second chamber is arranged around the first chamber, and the bottom of the first chamber and the bottom of the second chamber are connected. A drain port is provided at the bottom of the first chamber. The turbulence section is located inside the second chamber and is used to create a swirling flow of white water. The filtration section is located inside the first chamber and is used to filter the white water flowing into the first chamber from the bottom of the second chamber. The inlet pipe is connected to the second chamber and is used to input the white water to be treated into the first chamber. The outlet pipe is connected to the top of the first chamber. The white water fiber filtration device provided by this utility model solves the problem that the direct recycling of wastewater generated in filter paper production in the prior art will cause damage to production equipment and affect the quality of filter paper.

[0004] In the aforementioned patent, the outlet pipe is connected to the top of the first chamber, and as can be seen from the attached drawings, the diameter of the outlet pipe is much smaller than the inner diameter of the first chamber. Therefore, when the outlet pipe draws out the filtered water from the first chamber, if the level of the filtered water drops below the port of the outlet pipe, it becomes difficult to continue drawing out the filtered water, making it difficult to completely draw out the filtered water from the first chamber. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model proposes a white water fiber filtration device.

[0006] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

A feed pipe is connected to the upper end of the feed channel.

[0010] The filter assembly includes a stopper block that is matched and disposed in the inner shell. Several suction tubes are vertically inserted through the stopper block. The lower end of each suction tube extends into the sedimentation chamber and is provided with a filter element. The upper ends of the suction tubes are connected to the same water pumping pipe.

[0011] In a preferred embodiment, the feeding channel is spirally wound around the side wall of the inner shell in the vertical direction, and several blocking blocks are provided on the inner walls on both sides of the feeding channel along the extension direction of the feeding channel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] A white water fiber filtration device, comprising:

[0024] The outer casing 1 is arranged in a vertical cylindrical shape. The lower end of the outer casing 1 is tapered downward and has a waste discharge port 4. The waste discharge port 4 is equipped with a valve.

[0025] The inner shell 6 is arranged in a vertical cylindrical shape and is located inside the outer shell 1. A sedimentation chamber 7 is formed between the lower end of the inner shell 6 and the waste outlet 4 inside the outer shell 1. A feed channel 8 communicating with the sedimentation chamber 7 is provided between the side wall of the inner shell 6 and the side wall of the outer shell 1. A feed pipe 2 is connected to the upper end of the feed channel 8.

[0026] The filter assembly includes a plug 10 matched and disposed within the inner shell 6. A plurality of suction tubes 11 are vertically inserted through the plug 10. The lower end of the suction tubes 11 extends into the sedimentation chamber 7 and is provided with a filter element 13. The upper ends of the plurality of suction tubes 11 are connected to the same water pumping pipe 3.

[0027] White water is fed into the feed channel 8 through the feed pipe 2 and then transported to the sedimentation chamber 7. The water pump is connected to the water pump pipe 3 and is connected to several suction pipes 11. When the water pump is started, water can be drawn directly from the sedimentation chamber 7 and filtered when the water flows through the filter element 13. Since the suction pipes 11 are set vertically, the filter element 13 filters in the vertical direction. The filtered fibers are collected in the sedimentation chamber 7. A transparent viewing window can be provided on the outer wall of the sedimentation chamber 7 to observe the accumulation of fibers in the sedimentation chamber 7 at any time. When there are many fibers, the feeding is stopped and the valve is opened to discharge the filtered fiber slurry from the waste outlet 4.

[0028] This invention enables the complete extraction of water filtered by filter element 13.

[0029] In a preferred embodiment, the feeding channel 8 is spirally wound around the side wall of the inner shell 6 in the vertical direction, and a plurality of blocking blocks 9 are provided on the inner walls of both sides of the feeding channel 8 along the extension direction of the feeding channel 8.

[0030] Referring to the utility model with publication number "CN 213506282 U", a retention aid is added to the white water. When the white water passes through the spiral feed channel 8, it will generate a swirling flow, which makes the retention aid mix evenly with the fiber in the white water. This helps most of the fiber to settle in the sedimentation chamber 7, and the filter element 13 only needs to filter some of the unsettled fibers, reducing the filtration burden of the filter element 13.

[0031] In addition, blocking blocks 9 are set on both sides of the feed channel 8 so that when white water passes through the feed channel 8, the flow velocity on both sides is less than the flow velocity of the unblocked part in the middle. The difference in the flow velocity of white water will generate vortices and turbulence, thereby further accelerating the mixing of retention aid and fiber and improving efficiency.

[0032] In a preferred embodiment, the filter element 13 is detachably disposed at the lower end of the suction tube 11, and the lower end of the suction tube 11 is threadedly connected to a vertical filter cylinder 12, with the filter element 13 fixed inside the filter cylinder 12.

[0033] The filter element 13 is located inside the filter cartridge 12, so the filter element 13 can be replaced simply by replacing the filter cartridge 12.

[0034] In a preferred embodiment, a supporting edge 14 protrudes from the inner wall of the inner shell 6. The plug 10 is inserted into the inner shell 6 from top to bottom and supported on the supporting edge 14. A handle 16 is provided at the upper end of the plug 10. A top cover 5 is provided at the upper end of the inner shell 6. The water suction pipe 3 is provided on the top cover 5. The water suction pipe 3 is connected to the upper ends of several suction pipes 11 through several connecting hoses.

[0035] The plug 10 can be detached and placed in the inner shell 6. The plug 10 can be removed by the handle 16, which makes it easy to replace the filter element 13 and clean it.

[0036] In a preferred embodiment, the inner wall of the inner shell 6 is provided with at least one waterproof rubber ring 15, which is located above the support edge 14 and is tightly fitted to the side wall of the plug 10.
