Description

Technical Field

[0001] This disclosure relates to a flushing assembly for a conical filter. Background Technology

[0002] In chemical production processes, a combination of pipelines and pumps is typically used to transfer various fluids (such as the various materials required for the production process). To prevent impurities carried by the fluid from entering the pump and causing damage, a filter needs to be installed upstream of the pump to remove these impurities.

[0003] A common type of filter used in pipes with larger diameters is the cone filter. A cone filter is installed such that the apex of its cone points in the opposite direction to the fluid flow. In other words, the cone filter is installed with the apex of its cone located upstream of the bottom surface.

[0004] However, depending on the characteristics of the transferred material and environmental conditions, organic matter may sometimes precipitate from the material during the filtration process using a conical filter. This precipitated organic matter tends to adhere to the filter surface, causing partial or complete clogging of the filter and consequently affecting the operation of downstream pumps. Utility Model Content

[0005] A flushing assembly is proposed that can prevent or completely eliminate the precipitation of organic matter on a conical filter in a pipeline. This flushing assembly can be retrofitted to existing pipelines without requiring a complete redesign of the pipeline system. The flushing assembly can be easily separated from the pipeline for easy repair and maintenance of the pipeline or its components.

[0006] According to one aspect of this disclosure, a flushing assembly for a conical filter is provided, the conical filter being disposed in a conduit and positioned such that the apex of the conical filter points in a direction opposite to the flow direction of material in the conduit, the conduit having at least one opening at the location of the conical filter, characterized in that the flushing assembly comprises: at least one fixing device, each fixing device configured to be detachably and sealingly mounted at one of the at least one opening in the conduit; at least one nozzle disposed within the conduit, each nozzle configured to spray flushing liquid toward a surface of the conical filter, the nozzles being arranged such that the nozzles are located near and upstream of the conical filter, and the nozzles are positioned in the flow direction of the material within a range from the apex of the conical filter to an intermediate cross section along the height of the conical filter; at least one rigid conduit, each conduit being fluidly connected to a corresponding nozzle and configured to supply the flushing liquid from outside the conduit to the nozzle, each conduit being configured to pass through the corresponding fixing device and be sealingly fixed to the fixing device; and a pump configured to pump the flushing liquid through the at least one conduit.

[0009] In one embodiment, the at least one pipeline is welded to the corresponding fixing device.

[0010] In one embodiment, the injection head is a Venturi nozzle.

[0011] In one embodiment, the flushing assembly further includes a support for the at least one pipeline, the support being located inside the pipeline and extending from the fixing device to the respective pipeline.

[0012] In one embodiment, the at least one pipeline includes a pipeline head and a pipeline body, the pipeline head of each pipeline being configured to pass through and be sealed to a corresponding fixing device, and one end of the pipeline head being fluidly connected to a corresponding injection head, and the other end of the pipeline head being fluidly connected to the pipeline body.

[0013] In one embodiment, the flushing assembly further includes a flow meter and / or pressure gauge for the flushing liquid disposed on the at least one pipeline.

[0021] The present disclosure will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure more complete and to fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments.

[0022] It should be understood that the same reference numerals denote the same elements in all the accompanying drawings. For clarity, the dimensions of certain features may be modified in the drawings.

[0023] It should be understood that the terminology used in this specification is for describing specific embodiments only and is not intended to limit this disclosure. All terms used in this specification (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0024] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms.

[0027] Figure 1 A flushing assembly 100 for a conical filter according to the present disclosure is shown.

[0028] A conical filter 200 is disposed in the pipe 300. The conical filter 200 is positioned such that the apex of its cone points in the opposite direction to the flow direction W of the material in the pipe 300. The maximum diameter portion of the conical filter 200 is adapted to the inner diameter of the pipe 300, thereby achieving filtration of all material heading downstream.

[0029] The pipe 300 has an opening 310 at the location of the cone filter 200. The opening 310 is openable to allow access to the interior of the pipe 300 and the cone filter 200 for operations such as repair or maintenance.

[0030] The flushing assembly 100 according to this disclosure includes a fixture 10, a spray head 30, a pipeline 60, and a pump 90.

[0031] The fixing device 10 serves as a connecting part to connect the flushing assembly 100 to the pipe 300. The fixing device 10 is configured to be detachably and sealingly installed at the opening 310 of the pipe 300.

[0032] The fixing device 10 can be in the form of a flange. In this embodiment, the fixing device 10 can be detachably installed to the wall of the pipe 300 by bolts. A sealing gasket is provided between the fixing device 10 and the wall of the pipe 300 to achieve a seal between the fixing device 10 and the pipe 300.

[0033] A spray head 20 is disposed within the conduit 300. The spray head 20 is configured to spray flushing liquid toward the surface of the cone filter 200. The spray head 20 is arranged such that it is attached to and upstream of the cone filter 200. In other words, the spray head 20 is... Figure 1 The nozzle 20 is positioned near the top of the cone filter 200. The nozzle 20 is also arranged such that it is positioned along the material flow direction W within the range from the apex of the cone filter 200 to the midpoint of the cone filter 200's height. That is, the nozzle 20 is positioned along the flow direction W... Figure 1 Within the range indicated by the mark P, the dashed line at the bottom in the attached figure passes through the midpoint of the height of the conical filter.

[0034] The spray head 20 is used as a terminal actuator to spray flushing liquid onto the surface of the cone filter 200. The flushing liquid sprayed from the spray head 20 can interfere with the precipitation and adhesion of organic matter on the surface of the cone filter 200, so that the organic matter that might have been precipitated will continue to dissolve in the material, pass through the cone filter 200 and reach the downstream.

[0035] The spray head 20 can spray flushing liquid towards the conical filter 200 parallel or perpendicular to the flow direction W. However, it is understood that the spray head 20 can also be oriented to spray flushing liquid towards the conical filter 200 at any other angle relative to the flow direction W, such as 45 degrees relative to the flow direction W, etc. Preferably, the spray head 20 sprays flushing liquid parallel to the flow direction W.

[0036] The spray head 20 can be a nozzle of various types, such as a direct-flow nozzle or a Venturi nozzle. Preferably, the spray head 20 is a Venturi nozzle. The Venturi nozzle can draw the surrounding fluid into the sprayed fluid while spraying the flushing liquid, which can increase the amount of sprayed fluid and increase the disturbance to the fluid around the cone filter 200, thereby further hindering the precipitation of organic matter on the surface of the cone filter.

[0037] The spray head 20 can be configured to continuously spray flushing liquid, for example, spraying 7 to 10 cubic meters of flushing liquid per hour. However, those skilled in the art will understand that, depending on process requirements, the spray head 20 can also be configured to intermittently spray flushing liquid at a certain frequency.

[0038] The conduit 30 is rigid. The conduit 30 is fluidly connected to the nozzle 20. The conduit 30 is configured to supply flushing fluid to the nozzle 20 from the outside of the conduit 300, and is configured to pass through and be securely fixed to the fixing device 10. The conduit 30 serves as an input conduit for the flushing fluid, delivering the flushing fluid to the nozzle 20. Furthermore, by being fixed to the fixing device 10, the rigid conduit 30 also serves as a support to support the nozzle 20 within the conduit 300.

[0039] The conduit 30 can be welded to the fixture 20. By welding, the conduit 30 can be configured to be securely fixed to the fixture 20.

[0040] The pipeline 30 may include a pipeline head 32 and a pipeline body 34. The pipeline head 32 is configured to pass through and be securely fixed to the fixing device 10. One end of the pipeline head 32 is fluidly connected to the injection head 20, while the other end of the pipeline head 32 is fluidly connected to the pipeline body 34. Figure 1 In the figure, the conduit head 32 is shown with a thick solid line, while the conduit body 34 is shown with a thin solid line. It is understood that the distance from the other end of the conduit head 32 through the fixture 10 to the outside of the conduit 300 is schematic in the figure and can vary as needed. For example, the other end of the conduit head 32 can be flush with the outer surface of the fixture 10. The arrangement of the conduit 30 consisting of the conduit head 32 and the conduit body 34 allows for easier removal of the fixture 10.

[0041] The pipeline 30 can be directly connected to the spray head 20 at one end by a threaded connection, but without departing from the scope of this disclosure, other connection methods can also be used between the pipeline 30 and the spray head 20. For example, in the embodiments of this disclosure, the spray head 20 and the pipeline 30 are fixedly connected by a threaded connection, but to facilitate adjustment of the spray direction of the spray head 20, an adjustable or non-adjustable elbow can be inserted between the spray head 20 and the pipeline 30. Thus, the elbow connects the spray head 20 and the pipeline 30. After the flushing assembly 100 is removed from the pipeline 300, the spray direction of the spray head 20 can be adjusted by directly adjusting the adjustable elbow or by replacing different non-adjustable elbows without replacing the pipeline 30. When a pipeline head 32 is provided, the pipeline head 32 can provide the function of the aforementioned elbow.

[0042] The conduit 30 can be made of any suitable rigid material. Preferably, the conduit 30 is made of stainless steel.

[0043] Pump 40 is configured to pump the flushing liquid through line 30.

[0044] exist Figure 1 In one embodiment, pump 40 is shown to be a separate pump located outside the conduit 300. In this case, the flushing assembly 100 may also include a storage device for containing flushing fluid, the storage device being in communication with the conduit 30. The storage device may be a storage tank, storage vessel, or any other container capable of holding liquid.

[0045] The flushing liquid sprayed by nozzle 20 can be water or the same as the material in pipe 300. If the flushing liquid is the same as the material, pump 40 can also be a pump located downstream of conical filter 200 in pipe 300. In this embodiment, pump 40 pumps material that has at least passed through conical filter 200 and reached further downstream as flushing liquid through pipe 30.

[0046] The flushing assembly 100 may also include a flow meter 50 and / or a pressure gauge 60. The flow meter 50 and pressure gauge 60 are disposed on the pipeline 30 to monitor the flow rate and pressure of the flushing fluid within the pipeline 30. Those skilled in the art will understand that the flushing assembly 100 may also include other suitable sensing elements disposed on the pipeline 30 to monitor various characteristics of the flushing fluid within the pipeline 30.

[0047] like Figure 2As shown, the flushing assembly 100 may further include a support 70 for the line 30. The support 70 is located inside the line 300 and extends from the fixture 10 to the line 30. The support 70 serves to support the line 30 relative to the fixture 10 inside the line 300, thereby further enhancing the support for the spray head 20 inside the line 300 beyond the support provided by the line 30.

[0048] In this embodiment, as Figure 1 As shown, the conduit 300 has an opening 310, with the flushing assembly 100 according to this disclosure disposed relative to the opening 310. However, those skilled in the art will understand that the flushing assembly 100 according to this disclosure can be used for conduits having multiple openings without departing from the scope of this disclosure.

[0049] For example, such as Figure 1 As shown, the conduit 300 also has a spare opening 320 opposite to the opening 310 in terms of the conduit diameter. The flushing assembly 100 may also be arranged relative to the other opening 320. In this embodiment, the flushing assembly 100 may include two fixing devices 310, two spray heads 20, and two lines 30. In this embodiment, each fixing device 310, spray head 20, and line 30 is as described above for the embodiment with respect to a single opening 310, except that the two fixing devices 310, two spray heads 20, and two lines 30 are respectively provided at the opening 310 and the other opening 320, such that each opening is provided with its own fixing device 310, spray head 20, and line 30.

[0050] In this embodiment, the flushing assembly 100 may include a pump 40 for pumping flushing fluid through two lines 30. Alternatively, the flushing assembly 100 may include two pumps 40, each pumping flushing fluid through one of the lines 30.

[0051] The above describes an embodiment of the flushing assembly 100 according to the present disclosure for a pipe 300 having two openings. However, it is understood that the flushing assembly 100 according to the present disclosure can be arranged for pipes 300 having more similar openings, such as pipes 300 having three, four or more similar openings, as long as the space within the pipe 300 can accommodate the spray head 20 and the conduit 30 of the flushing assembly 100.

[0052] With the aid of the flushing assembly 100 according to this disclosure, a technician can install the flushing assembly 100 according to this disclosure on the basis of existing pipelines through pipe openings. Specifically, a technician can detachably and sealingly install the fixing device 10 at the pipe opening, and arrange the spray head 20 near and upstream of the conical filter in the pipeline by means of a pipeline passing through and fixed to the fixing device 10. Thus, by setting the spray head 20 to spray flushing liquid toward the surface of the conical filter, the precipitation and adhesion of organic matter on the surface of the conical filter is disturbed.

[0053] The installation of the component 100 according to this disclosure on the pipeline does not require redesign of the pipeline itself. In addition, since the flushing component 100 is installed on the pipeline by means of a detachable fixing device 10, the flushing component 100 can be easily separated from the pipeline by removing the fixing device 10, so as to facilitate maintenance and repair of the pipeline itself or the flushing component 100.

[0054] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims. This disclosure is defined by the appended claims, and equivalents of those claims are also included.
