Description
Technical Field
The utility model relates to a temporary filter is used to pipeline.
Background
In the petrochemical industry, before the device is officially driven, the solid impurities remained in the equipment (including pumps, compressors and the like) and pipelines need to be flushed by liquid or gas, and the temporary filter arranged on the pipelines is used for filtering and removing the solid impurities, so that the equipment, valves, instruments and the like are prevented from being damaged by the influence of the solid impurities, and the normal operation and use of the equipment after driving are ensured. The temporary filter is only used temporarily before the device is driven, and the temporary filter is removed after the pipeline is cleaned. When the device is in normal operation, the temporary filter is not used.
In the petrochemical industry, the conventional temporary filter for the pipeline is generally a pointed cone type filter or a flat cone type filter, and is inconvenient to assemble and disassemble. Especially for large-diameter pipelines, a special disassembly short joint needs to be arranged for disassembling and assembling the temporary filter, so that leakage points of a pipeline system are increased. After the temporary filter is dismantled, need set up the backing ring and compensate the clearance that the temporary filter retainer plate left, the backing ring both sides still respectively need set up a gasket and flange face is sealed, has also increased the risk of pipeline leakage.
Disclosure of Invention
The utility model aims at providing a temporary filter for pipeline to solve the dismouting that current temporary filter for pipeline exists inconvenient, make the pipe-line system leakage point increase scheduling problem.
In order to solve the above problem, the utility model adopts the following technical scheme: the utility model provides a temporary filter for pipeline is equipped with the filter core, and the entry end of filter core has the hem, its characterized in that: the temporary filter for the pipeline is also provided with a filter element pipe, the two ends of the filter element pipe are respectively provided with a filter element pipe inlet flange and a filter element pipe outlet flange, the inner wall of the central hole of the filter element pipe inlet flange is provided with a baffle ring, the folded edge of the filter element inlet end is positioned between the baffle ring and the orifice of the central hole of the filter element pipe inlet flange on the end surface of the flange, the other end of the filter element is positioned in the filter element pipe, the filter element pipe is provided with a discharge pipe, and the outlet of the.
Adopt the utility model discloses, following beneficial effect has: (1) the temporary filter for the pipeline is connected with the pipeline through the filter element pipe inlet flange and the filter element pipe outlet flange, is convenient to disassemble and assemble, is safe and reliable, and can reduce leakage points of a pipeline system. (2) The length of the temporary filter can be made to correspond to the length of a standard valve (e.g., a gate valve) of the same pressure rating and the same nominal diameter on the pipe. Thus, the valve can be detached and the temporary filter can be installed; the temporary filter is detached from the pipeline after being used, and the valve is installed again, so that the interchangeability is strong. (3) The filter element pipe inlet flange, the filter element pipe outlet flange and the temporary filter can be standard sizes in structural length, can be used for a plurality of pipelines with the same specification and can be reused, and the economic efficiency is better. After the temporary filter finishes filtering and takes out the filter element, the temporary filter can also be used as a section of pipeline. (4) The filter element with different filtering precision can be replaced according to the requirements of different filtering precision. (5) The temporary filter is provided with a discharge pipe which can discharge residual liquid entering the filter element pipe after filtration, so that the residual liquid is discharged completely. The discharge pipe can also be used as a purging pipe before the device is started; the temporary filter is filled with steam or nitrogen through a valve at the outlet of the discharge pipe and a purging pipe, so that the pipeline can be purged.
The utility model discloses can be used to various industry pipelines, temporary filtration washing liquid or gaseous equipment and the remaining solid debris in the pipeline smugglied secretly.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The drawings and detailed description do not limit the scope of the invention as claimed.
Drawings
Fig. 1 is a schematic structural diagram of the temporary filter for pipelines according to the present invention.
Detailed Description
Referring to fig. 1, the temporary filter for pipeline (referred to as temporary filter for short) of the present invention is provided with a filter element 2, and the inlet end of the filter element 2 is provided with a folded edge 8. The temporary filter is also provided with a filter element pipe 1, and both ends of the filter element pipe 1 are respectively provided with a filter element pipe inlet flange 6 and a filter element pipe outlet flange 7. The inner wall of the central hole of the filter element pipe inlet flange 6 is provided with a baffle ring 3, and the folded edge 8 at the inlet end of the filter element 2 is positioned between the baffle ring 3 and the hole opening of the central hole of the filter element pipe inlet flange 6 on the end surface of the flange. When the flange 8 comes into contact with the stop ring 3, the stop ring 3 can define the position of the filter cartridge 2 and prevent the filter cartridge 2 from moving towards the cartridge tube outlet flange 7. The other end of the filter element 2 is positioned in the filter element pipe 1, and is generally positioned in the middle of the length of the filter element pipe 1.
The filter element pipe 1 is provided with a discharge pipe 4, and the outlet of the discharge pipe 4 is connected with the valve 5 through a discharge pipe flange 9. The discharge pipe 4 is generally perpendicular to the filter element pipe 1 and is welded to the filter element pipe 1. The filter core tube 1 and the discharge tube 4 are steel tubes having a circular cross section.
The filter element 2 generally adopts a standard cone-type filter; specifically, the screen or the hole filter may be a screen or a hole filter of a pointed cone type, or a screen or a hole filter of a truncated cone type. The filter element 2 shown in fig. 1 is a wire mesh filter of the truncated cone type.
The filter element pipe 1 is made of a steel pipe with the same specification as the pipeline, and two ends of the filter element pipe are respectively connected with the filter element pipe inlet flange 6 and the filter element pipe outlet flange 7 in a butt welding mode. The filter element tube inlet flange 6 and the filter element tube outlet flange 7 can also be integrally forged or cast with the filter element tube 1. The filter element pipe inlet flange 6 and the filter element pipe outlet flange 7 are standard flanges with the same specification as the pipeline. The baffle ring 3 is generally made of a steel plate with the thickness of 2-3 mm and welded on the inner wall of the central hole of the inlet flange 6 of the filter element pipe; the retainer ring 3 can also be integrally forged and machined with the filter element pipe inlet flange 6. The nominal diameter of the discharge pipe 4 is generally DN 15-DN 40, and the valve 5 is a flanged gate valve generally DN 15-DN 40.
The utility model discloses when using, through filter element pipe entry flange 6 and filter element pipe export flange 7 and pipe connection. Liquid or gas used for washing solid impurities in the pipeline enters the filter element 2 through the filter element pipe inlet flange 6 and the inlet end of the filter element 2, and the filter element 2 filters the solid impurities. The filtered liquid or gas enters the filter element pipe 1 and flows out through the outlet flange 7 of the filter element pipe. The residual liquid in the filter element tube flows out of the discharge tube 4 and the valve 5. The valve 5 is closed except for being opened when discharging residual liquid and purging the pipeline with steam or nitrogen.
