Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a PVDF ultrafiltration device for effectively removing yellow mud in water.

Referring to fig. 1, a PVDF ultrafiltration device for effectively removing yellow mud in water comprises a housing 100, a PVDF ultrafiltration core 200 and a pre-filter cloth 300, wherein the housing 100 comprises a filter cartridge 110 with one open end and an end cap 120, the end cap 120 is fixedly connected to the open end of the filter cartridge 110 through a bolt 121, and then the end cap 120 plugs the filter cartridge 110. The end cap 120 is fixedly connected with an inlet pipe 122, and the inlet pipe 122 is communicated with the inside of the filter cartridge 110. One end of the filter cartridge 110 opposite to the end cover 120 is fixedly connected with a water outlet pipe 111, and the water outlet pipe 111 is communicated with the inside of the filter cartridge 110. The PVDF ultrafiltration core 200 is conical, the PVDF ultrafiltration core 200 is arranged in the filter cartridge 110, and the pointed end of the PVDF ultrafiltration core 200 is arranged close to the water outlet pipe 111. The pre-filter cloth 300 is arranged in the filter cartridge 110, and the pre-filter cloth 300 is positioned at one end of the PVDF ultrafiltration core 200, which is far away from the water outlet pipe 111.

When the PVDF ultrafiltration device is used for filtering yellow mud in water, water is introduced into the filter cartridge 110 through the water inlet pipe 122, the yellow mud in the water is pre-filtered by the pre-filter cloth 300, the yellow mud with small particle size passes through the pre-filter cloth 300 and is blocked by the PVDF ultrafiltration core 200, and finally filtered water is discharged through the water outlet pipe 111, so that the amount of the yellow mud adhered to the PVDF ultrafiltration core 200 is reduced in the process, the situation that the yellow mud passes through the PVDF ultrafiltration core 200 due to large water pressure is reduced, and the removal effect of the PVDF ultrafiltration device on the yellow mud is further improved.

Referring to fig. 1 and 2, in order to increase the stability of the PVDF ultrafiltration core 200, a limiting ring 112 is coaxially and fixedly connected to the filter cartridge 110, a connection ring 210 is disposed at one end of the limiting ring 112 away from the water outlet pipe 111, and both the PVDF ultrafiltration core 200 and the pre-filter cloth 300 are fixedly connected to the connection ring 210. After the PVDF ultrafiltration core 200 is installed in the filter cartridge 110, the connection ring 210 abuts against the limit ring 112, so that the PVDF ultrafiltration core 200 is limited by the cooperation of the limit ring 112 and the connection ring 210, and the stability of the PVDF ultrafiltration core 200 is further improved.

After the water is introduced into the filter cartridge 110, the water in the filter cartridge 110 may pass through the gap between the connection ring 210 and the limiting ring 112, which in turn results in poor filtering effect of the PVDF ultrafiltration device on the yellow mud in the water.

With continued reference to fig. 1 and 2, in order to ensure the filtering effect of the PVDF ultrafiltration device on yellow mud in water as much as possible, an annular groove 113 is formed in the end surface of the limiting ring 112 facing the connection ring 210, and a sealing ring 114 is disposed in the annular groove 113. A sealing tube 123 is fixedly connected to the end surface of the end cap 120 facing the filter cartridge 110. After the end cap 120 is mounted on the filter cartridge 110, the outer wall of the sealing tube 123 abuts against the inner wall of the filter cartridge 110, the sealing tube 123 abuts against the connecting ring 210, the sealing tube 123 applies a force to the connecting ring 210 in the direction of the limit ring 112, the connecting ring 210 abuts against the sealing ring 114 and applies a pressure to the sealing ring 114, the sealing ring 114 deforms, the sealing ring 114 seals a gap between the connecting ring 210 and the limit ring 112, namely, the sealing performance between the connecting ring 210 and the limit ring 112 is increased, and further, the filtering effect of the PVDF ultrafiltration device on yellow mud in water is ensured as much as possible.

After the PVDF ultrafiltration device is used for a long time, more yellow mud is adhered to the pre-filter cloth 300, and the blocking effect of the pre-filter on the yellow mud is influenced.

With reference to fig. 1 and fig. 2, in order to ensure the blocking effect of the pre-filter cloth 300 on the yellow mud as much as possible, a C-shaped supporting rod 211 is arranged on the end surface of the connecting ring 210 departing from the limiting ring 112, both ends of the supporting rod 211 are fixedly connected with the connecting ring 210, an elastic rope 212 is fixedly connected on the supporting rod 211, and one end of the elastic rope 212 far away from the supporting rod 211 is fixedly connected with the pre-filter cloth 300. When water is introduced into the filter cartridge 110, the water applies a force towards the direction of the water outlet pipe 111 to the pre-filter cloth 300, so that the pre-filter cloth 300 drives the elastic rope 212 to move, and the elastic rope 212 is stretched; after water is stopped flowing into the filter cartridge 110, the elastic rope 212 exerts a pulling force on the pre-filter cloth 300 under the action of the elastic force thereof, so that the pre-filter cloth 300 moves towards the water inlet pipe 122, the yellow mud adhered to the pre-filter cloth 300 is separated from the pre-filter cloth 300 and falls to the bottom of the filter cartridge 110, and the blocking effect of the pre-filter cloth 300 on the yellow mud is ensured as much as possible.

Referring to fig. 1 and 3, in order to facilitate the worker to discharge yellow mud in the filter cartridge 110, a mud discharging pipe 400 is fixedly connected to the filter cartridge 110, the mud discharging pipe 400 is arranged corresponding to the connection ring 210, the mud discharging pipe 400 is communicated with the inside of the filter cartridge 110, and a sealing cover 410 is threadedly connected to one end of the mud discharging pipe 400 away from the filter cartridge 110. The mud pipe 400 is fixedly connected with a blocking cover 420, a mud falling hole 421 is formed in the center of the blocking cover 420, and the center of the blocking cover 420 protrudes outwards towards the sealing cover 410. Yellow mud falling from the pre-filter cloth 300 falls into the mud discharging pipe 400, then the yellow mud passes through the mud falling hole 421 and falls to the bottom of the mud discharging pipe 400, then the sealing cover 410 is unscrewed, the yellow mud in the mud discharging pipe 400 is discharged, and further the effect that the yellow mud in the filter cartridge 110 is conveniently discharged by a worker is achieved.

In addition, the blocking cover 420 can block the yellow mud entering the mud discharging pipe 400, and reduce the situation that the yellow mud enters the filter cartridge 110 again in a reverse direction.

The implementation principle of the PVDF ultrafiltration device for effectively removing yellow mud in water in the embodiment of the application is as follows: when the PVDF ultrafiltration device is used for filtering yellow mud in water, water is introduced into the filter cartridge 110 through the water inlet pipe 122, the yellow mud in the water is pre-filtered by the pre-filter cloth 300, the yellow mud with smaller particle size passes through the pre-filter cloth 300 and is blocked by the PVDF ultrafiltration core 200, and finally the filtered water is discharged through the water outlet pipe 111. After water stops flowing into the filter cartridge 110, the elastic rope 212 applies a pulling force towards the water inlet pipe 122 to the pre-filter cloth 300, the pre-filter cloth 300 moves towards the direction close to the water inlet pipe 122, so that the yellow mud falls from the pre-filter cloth 300 and enters the mud pipe 400, the sealing cover 410 is taken down, and the yellow mud in the mud pipe 400 is discharged.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
