A pre-settling device for a pipeline filter

Abstract

This invention relates to a pre-settling device for a pipeline filter, comprising an inlet, an inner pipe, an outer pipe, an outlet, and a discharge valve. The pipes are vertically installed perpendicular to the ground. As the liquid flows through, heavier impurities settle at the bottom of the device due to gravity. Opening the discharge valve at the bottom allows for the rapid discharge of these settled impurities without shutting down the liquid supply. By adding this pre-settling device before the pipeline filter, the frequency of filter disassembly and cleaning can be effectively reduced, improving production efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of pipeline fluid transportation, and specifically relates to a pre-settling device for a pipeline filter. Background Technology

[0002] In daily industrial production, there is a frequent need for fluid transportation. Fluid transport pipelines often require the installation of pipeline filters to remove solid impurities from the fluid, ensuring the normal operation of machinery (including compressors, pumps, etc.) and instruments, achieving stable process flow, and guaranteeing safe and stable production. Common pipeline filters include Y-type filters, Z-type filters, T-type filters, and basket filters. Although these pipeline filters all have temporary impurity storage spaces, these spaces are generally small, requiring frequent disassembly and cleaning. Furthermore, disassembly and cleaning of pipeline filters requires machine shutdown, which is time-consuming and impacts production efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a pre-settling device for pipeline filters.

[0004] A pre-settling device for a pipeline filter consists of an inlet (1), an inner pipe (2), an outer pipe (3), an outlet (4), and a discharge valve (5). The inner pipe (2) and the outer pipe (3) are nested and coaxial. The diameter of the inner pipe (2) is smaller than that of the outer pipe (3), and the length of the inner pipe (2) is also smaller than that of the outer pipe (3). The inlet (1) is located at the top of the inner pipe (2), the outlet (4) is located on the upper part of the side wall of the outer pipe (3), and the discharge valve (5) is located at the bottom of the outer pipe (3).

[0005] Preferably, the total height of the pre-settling device of the pipeline filter is ≥20cm.

[0006] Preferably, the height difference between the inner pipe (2) and the outer pipe (3) is ≥ 30% of the total height, so that there is enough space at the bottom of the outer pipe (3) to accommodate the sedimented impurities.

[0007] Preferably, the diameter difference between the inner pipe (2) and the outer pipe (3) is greater than or equal to 30% of the diameter of the outer pipe (3), which increases the probability of trapping larger solid impurities.

[0008] Preferably, the horizontal height of the discharge port (4) is higher than the horizontal position of the bottom of the inner pipe (2); more preferably, the discharge port (4) is located at the top of the outer pipe (3);

[0009] Preferably, the discharge valve (5) is a butterfly valve, which facilitates quick opening and closing and discharge of impurities.

[0010] Preferably, the discharge valve (5) is a triple eccentric butterfly valve to prevent particle wear from affecting the valve's sealing performance.

[0011] This invention, by adding the aforementioned pre-sedimentation device before the pipeline filter, can effectively reduce the frequency of disassembly and cleaning of the pipeline filter, and improve operational convenience and production efficiency. Attached Figure Description

[0012] Figure 1 This is a cross-sectional schematic diagram of the pre-settling device for the pipeline filter proposed in this utility model.

[0013] The meanings of the labels in the diagram are as follows: 1-Inlet, 2-Inner pipe, 3-Outer pipe, 4-Outlet, 5-Drain valve. Detailed Implementation

[0014] The specific technical solutions of this utility model will be described in detail below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, and not all embodiments.

[0015] like Figure 1 As shown, a pre-settling device for a pipeline filter includes: an inlet (1), an inner pipeline (2), an outer pipeline (3), an outlet (4), and a waste discharge valve (5).

[0016] In this embodiment, the pre-filter settling device is installed before the pipeline filter. The settling device is installed vertically to the ground, and a certain amount of working space should be left at the bottom of the discharge valve (5). During normal liquid transportation, the discharge valve (5) is in the closed state. When there are large impurities in the transported liquid, due to gravity, the impurities will accumulate and deposit at the bottom of the outer pipeline (3). When a large amount of sediment accumulates, the discharge valve (5) can be opened directly, and some of the transported liquid will flush out the deposited impurities. Then, the discharge valve (5) can be quickly closed to complete the discharge process without interrupting the transport of the liquid.

[0017] The above description is only for illustrating the technical solution of this utility model, but the protection scope of this utility model is not limited thereto. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the protection scope of this utility model.
