Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and in particular relates to a straight-through pipeline filter. Background Art

[0002] Pipeline filters are widely used for filtering particles in various liquid and gas media such as petrochemical pipelines, power station boiler pipelines, pharmaceutical industry, and domestic water supply, so as to ensure the quality of the media and the normal operation of the equipment. Since the use of blue filters in medium pipelines is large, traditional blue filters are subject to structural limitations such as high installation height, and the lower filter element is prone to accumulation of filtered dirt and reduced filtration area, increased flow resistance, short filter element cleaning cycle, and difficult pipe installation.

[0003] For example, the Chinese utility model patent with authorization announcement number CN201366279Y discloses a straight-through pipe filter. Although the center lines of the water inlet 2 and the water outlet 4 are on the same axis, the internal water inlet of the filter element 3 is directly connected to the water inlet 2, which easily forms a dirt collecting area at the bottom of the shell, causing particles or dirt to adhere to the inner wall of the filter element, increasing the flow resistance of the filter element, thereby making the filtration accuracy poor and shortening the cleaning cycle of the filter element; at the same time, the filter element 3 is not fixed, and the filter element is prone to shaking when the water flow is large, causing leakage. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a straight-through pipeline filter.

[0005] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0006] A straight-through pipe filter comprises a shell, in which an inclined filter element seat and a filter element mounted on the filter element seat are arranged, and the side wall of the shell is provided with an inlet pipe, an outlet pipe and a sewage discharge assembly for discharging waste, the inlet pipe is connected with the interior of the filter element through a flow hole on the filter element seat, the outside of the filter element is connected with the outlet pipe, and a detachable flange cover is installed at the upper end of the shell.

[0007] Preferably, a bottom plate is provided at the bottom of the shell, the bottom plate is inclined, and the bottom end of the bottom plate is lower than the sewage discharge assembly.

[0008] Preferably, the center lines of the inlet pipe and the outlet pipe coincide with each other, and the filter element seat is arranged at an angle of 45° to the side wall of the housing.

[0009] Preferably, the lower end of the filter element is mounted on the filter element seat via a retaining ring, and an elastic clamping ring is provided between the upper end of the filter element and the flange cover.

[0010] Preferably, the flange cover is provided with a handle and a steam vent connected to the interior of the shell.

[0011] Preferably, the flange cover is detachably connected to the housing via a housing flange and a fastening assembly.

[0012] Preferably, a sealing gasket is provided between the flange cover and the housing flange.

[0013] Preferably, a support plate is provided on the outer periphery of the filter element.

[0014] Preferably, a base ring is provided at the bottom of the housing.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The elastic clamping ring always presses the filter element on the filter element seat under the action of elasticity. The elastic clamping ring is also used for extracting, cleaning and reinstalling the filter element, that is, the elastic clamping ring is also used as a handle when cleaning the filter element;

[0017] 2. A support plate is provided on the periphery of the filter element, which can prevent the filter element from tilting due to force and causing leakage;

[0018] 3. A base ring is provided at the bottom of the shell to support the filter itself and the connecting pipes, reducing the amount of pipe supports;

[0019] 4. The bottom plate of the shell is installed at an angle to form a dirt collection area at the bottom. The inner wall of the filter element no longer adheres to intercepted particles or dirt, effectively reducing the flow resistance. The filtration accuracy reaches 10 mesh to 200 mesh. The effective flow area of ​​the filter element can reach 2 to 6 times the existing one. In addition, the filtration area is large, the flow resistance is small, and the filter element cleaning cycle can be greatly extended.

[0020] 5. A retaining ring is provided on the upper part of the filter element seat to prevent the filter element from being displaced by force and to avoid the phenomenon that the medium is not filtered;

[0021] 6. A steam vent is provided on the flange cover to discharge the gas in the pipeline to prevent gas flow blocking;

[0022] 7. The inlet and outlet pipes are located below the shell to reduce the height from the pipe center to the bottom of the filter, increase the installation space, and facilitate on-site installation and construction. The minimum installation height from the outer edge of the pipe flange to the installation base surface is 100mm;

[0023] In summary, the utility model solves the shortcoming of the existing blue filter that the inlet and outlet are too high. The utility model has a compact structure, a low pipeline installation height, a large effective filtration area, a long cleaning cycle, convenient sewage discharge, and safe and reliable operation.

[0029] Embodiment 2:

[0030] A straight-through pipe filter is different from Example 1 in that a bottom plate 3 is provided at the bottom of the shell 2, the bottom plate 3 is inclined, and the bottom end of the bottom plate 3 is lower than the sewage discharge component 17.

[0031] Furthermore, the inlet pipe 16 is installed below the filter element 7, the center lines of the inlet pipe 16 and the outlet pipe 6 coincide, and the filter element seat 4 is set at 45° to the side wall of the shell 2, and the outlet pipe 6 and the inlet pipe 16 are on the same axis on the shell 2, which facilitates the unified layout of the pipelines.

[0032] Furthermore, the lower end of the filter element 7 is installed on the filter element seat 4 through the retaining ring 5, and an elastic clamping ring 11 is arranged between the upper end of the filter element 7 and the flange cover 10. The elastic clamping ring 11 always presses the filter element 7 on the filter element seat 4 under the action of elasticity. The elastic clamping ring 11 is also used for removing, cleaning and reinstalling the filter element 7.

[0033] Furthermore, the flange cover 10 is provided with a handle 12 and a steam vent 13 connected to the interior of the housing 2. The steam vent 13 is provided on the flange cover 10 to discharge the gas in the pipeline, thereby preventing the occurrence of gas flow blocking.

[0034] Furthermore, the flange cover 10 is detachably connected to the housing 2 via the housing flange 9 and the fastening assembly 14 , and a sealing gasket 15 is provided between the flange cover 10 and the housing flange 9 .

[0037] The working principle of the utility model is:

[0038] The liquid medium or gas enters through the inlet pipe 16 and then reaches the interior of the filter element 7 through the flow hole 18 on the filter element seat 4, effectively filtering impurities in the medium, and then flows out evenly from all sides through the filter element 7. After filtration, the impurities are mostly collected in the sewage collection area on the bottom plate 3 under the scouring of the medium weight and the medium flow. The bottom plate 3 is tilted in the shell 2 to facilitate the discharge of sewage. Then the sewage discharge component 17 opens the valve to discharge the sewage in the shell 2. The inlet and outlet of the utility model are arranged at the lower end of the filter, which can effectively reduce the installation height and increase the installation space, and will not cause the phenomenon of being unable to install and construct due to insufficient installation space on site.
