Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a tubular membrane filtering device. Background Art

[0002] The tubular filter is a micron-level filtration device composed of a rigid porous filter medium. The tubular filter is a precision filtration device with a small footprint, large processing capacity, high degree of automation, and can achieve very high filtration accuracy. It is widely used in the petroleum, pharmaceutical, chemical, metallurgical and other industries, and is used in the petroleum, chemical (activated carbon, barium sulfate of photographic film, barium sulfate of lead powder, silicon sulfate, methanol, crystal salt, sulfuric acid bath, sodium bisulfate), acid bath and sulfur of chemical fiber, pharmaceutical (tetracycline crystals, glucose syrup, fermentation filtrate of antibiotics, vitamin E, injection medicine and hydrogen peroxide); food, hydrometallurgy; fertilizer; ultrafine metal powder, inorganic salt powder, crystal, catalyst and other industries.

[0003] Since the membrane tubes in the current tubular ultrafiltration membrane filters cannot be graded for filtration, the effect is poor and the filtration is not complete. The filtered liquid cannot achieve the expected effect. At the same time, when filtering, the liquid falls into the filter screen and causes impact, which will damage the filter screen and affect the filtration effect.

[0004] In this regard, the current application number CN201920341621.4 proposes a tubular ultrafiltration membrane filter, although the device includes a main pipe, a branch pipe, a flange, a flange cover and a filter element, the circumferential surface of the main pipe is connected with a branch pipe, and the bottom of the flange is fixedly connected to the top of the flange cover by a connector, and the utility model relates to the technical field of filters. The tubular ultrafiltration membrane filter has a mounting plate fixedly connected to the inside of the filter element, and an ultrafiltration membrane is fixedly connected to the inside of the mounting plate. The ultrafiltration membrane includes a support layer and a separation layer, and the top of the support layer is bonded to the bottom of the separation layer by an adhesive. Such a device design can effectively improve the filtering effect on the liquid, and the filtering efficiency is high. By opening a first water outlet and a second water outlet at the bottom of both sides of the filter element, the first water outlet is internally threadedly connected to the first water outlet pipe. Such a device design can more conveniently install and replace the filter element, and it is convenient for people to replace and clean the filter element. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a tubular membrane filtration device includes a water inlet pipe 1, a first filter plate 2 is embedded in the water inlet pipe 1, a drainage pipe 3 is connected to the top of the first filter plate 2, a shell 4 is connected to the bottom of the water inlet pipe 1, a first tank body 5 is connected to the inside of the shell 4, a second filter plate 6 is connected to the inside of the first tank body 5, and a filter tube 7 is connected to the bottom of the first tank body 5.

[0022] During use of this embodiment, when it is necessary to filter the liquid, the liquid enters through the water inlet pipe 1. Since a first filter plate 2 is provided inside the water inlet pipe 1, the first filter plate 2 will perform a first filter on the liquid to block large particles in the liquid. At the same time, through the provision of the drainage pipe 3, the impact force of the liquid is reduced during filtration, thereby avoiding damage to the first filter plate 2 caused by the impact of the liquid. Subsequently, the liquid after the first filtration will fall from the water inlet pipe 1 into the interior of the first tank body 5, and will be filtered for the second time through the second filter plate 6. Subsequently, the liquid filtered for the second time will flow into each filter tube 7 for the final filtration, thereby obtaining filtered and purified liquid.

[0023] See also Figure 1-4 A first groove 8 is formed inside the water inlet pipe 1 , a limiting groove 9 is formed inside the first groove 8 , and a limiting block 10 is embedded inside the limiting groove 9 .

[0024] When the present solution is in use, the limit block 10 is fixedly connected to the first filter plate 2. The limit block 10 is embedded in the first groove 8, so that it slides down to the limit groove 9, and the first filter plate 2 is rotated so that the limit block 10 is embedded in the limit groove 9, thereby firmly fixing the first filter plate 2 in the water inlet pipe 1. At the same time, this arrangement also makes the installation and disassembly of the first filter plate 2 very convenient.

[0025] See also Figure 1-4 A circular hole 11 is opened at the bottom of the first tank body 5 , and the bottom of the filter tube 7 is connected to the second tank body 12 .

[0026] During use of this solution, through the setting of the circular hole 11, one end of the filter tube 7 passes through the circular hole 11 to connect to the first tank body 5, and the liquid filtered by the first filter plate 2 will fall into the interior of the first tank body 5, and then be filtered by the second filter plate 6, and then flow into the interior of the filter tube 7 driven by gravity.

[0027] See also Figure 1-4 The bottom of the second tank body 12 is connected to a water outlet pipe 13 , and the top of the second tank body 12 is also provided with a circular hole 11 .

[0028] During use of this solution, the other end of the filter tube 7 passes through the circular hole 11 and connects to the second tank body 12, so that the liquid completely filtered by the filter tube 7 will fall into the second tank body 12, and then flow out of the second tank body 12 through the outlet pipe 13, thereby obtaining filtered and purified liquid.

[0029] See also Figure 1-4 A support column 14 is connected to the bottom of the shell 4 , and an anti-slip pad 15 is connected to the bottom of the support column 14 .

[0030] During use, the present invention can fix and support the shell 4 by using the support column 14, and provide sufficient supporting force to ensure that the shell 4 can remain stable in various environments and usage conditions. The anti-slip pad 15 is mainly used to provide additional friction to prevent the shell 4 from sliding and improve safety.

[0031] See also Figure 1-4 The filter hole size of the first filter plate 2 is twice that of the second filter plate 6 , and the filter hole size of the second filter plate 6 is twice that of the filter tube 7 .

[0032] During use of this solution, by setting the filter hole sizes between the first filter plate 2, the second filter plate 6 and the filter tube 7 at the same time, the liquid will be graded and filtered by three different filter hole sizes. The graded filtration also makes the impurities in the liquid filtered step by step from large to small, and the filtration is more complete and the filtration effect is better, while ensuring that the liquid is fully filtered.

[0033] In the utility model, when using the device, the relevant technical personnel first engage the limit block 10 in the first groove 8 to slide it down to the limit groove 9, rotate the first filter plate 2 to make the limit block 10 engage with the limit groove 9, thereby firmly fixing the first filter plate 2 in the water inlet pipe 1. When it is necessary to filter the liquid, the liquid enters through the water inlet pipe 1. Since the first filter plate 2 is arranged inside the water inlet pipe 1, the first filter plate 2 will perform a first filter on the liquid to block large particles in the liquid. At the same time, through the arrangement of the drainage pipe 3, the impact force of the liquid is reduced during filtration, thereby avoiding damage to the first filter plate 2 caused by the impact of the liquid. Subsequently, the liquid after the first filtration will fall into the interior of the first tank body 5 through the water inlet pipe 1, and be filtered for the second time through the second filter plate 6. Subsequently, the liquid filtered for the second time will flow into each filter tube 7 for the final filtration, thereby obtaining filtered and purified liquid.
