Description

Technical Field

[0001] This utility model relates to a cyclone separator, and more particularly to a cyclone separator that can discharge impurities online. Background Technology

[0002] A hydrocyclone separator is a highly efficient decontamination device that uses centrifugal force to remove solid impurities from water. When water flows tangentially into the separator under pressure, it generates a strong swirling motion. Due to the density difference between solid impurities and water, under the influence of centrifugal force, centripetal force, and fluid drag, the less dense water rises and is discharged from the outlet, while the denser solid impurities sink to the bottom and are discharged from the slag discharge port. Existing hydrocyclone separators require opening the slag discharge valve for decontamination, which causes pressure and media leakage and necessitates shutdown for decontamination, impacting production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an online cyclone separator that solves the problem of difficulty in online sewage discharge in existing separators, making online sewage discharge operation of the cyclone separator more convenient and its performance superior, thereby meeting the greater needs of application development.

[0004] The technical solution of this utility model:

[0005] An online cyclone separator includes a cylinder, an inlet pipe, an outlet pipe, a filter screen, a flushing port, a slag collection well, and two valves. The inlet pipe is installed on the side wall of the cylinder, and the outlet pipe is installed at the upper end of the cylinder. A flushing port is provided on the side of the outlet pipe at the upper end of the cylinder. A filter screen is provided on the upper part of the inner side of the cylinder, and the filter screen is lower than the flushing port. The lower part of the cylinder is fixed on a support. A slag collection well is provided between the lower end of the cylinder and the slag discharge port. A valve is installed at the upper and lower ends of the slag collection well.

[0006] The beneficial effects of this utility model are:

[0007] 1. This application installs two valves and a slag collection well at the slag discharge port of the equipment. By adopting the combination of two flange butterfly valves and a slag collection well, the system pressure is isolated from the slag collection well by the order in which the flange butterfly valves are opened, thereby achieving no pressure leakage during slag discharge, smooth sewage discharge, and completing the online sewage discharge work with high efficiency.

[0008] 2. This application uses a drawer-type filter screen, which can be easily replaced without affecting the pipe connections. Especially during the initial stage of system operation, when there are many impurities in the pipes, a suitable filter screen can be selected. After the system has been running for a period of time, the filter screen can be replaced as needed.

This device overcomes the technical shortcomings of current separators, which are difficult to use for online wastewater removal. It makes online wastewater discharge operation of the cyclone separator more convenient, improves filtration efficiency, and enhances performance, thereby meeting the greater needs of application development.

[0023] It should be noted that in the description of this application, terms such as "inner", "outer", "upper", and "lower" that indicate direction or positional relationship are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] An online cyclone separator includes a cylinder 1, an inlet pipe 2, an outlet pipe 3, a filter screen 4, a flushing port 5, a slag collection well 6, and two valves 7. The inlet pipe 2 is mounted on the side wall of the cylinder 1, and the outlet pipe 3 is mounted on the upper end of the cylinder 1. A flushing port 5 is located on the side of the outlet pipe at the upper end of the cylinder 1. A filter screen 4 is located on the upper inner side of the cylinder 1, below the flushing port 5. The lower part of the cylinder 1 is fixed to a support leg 16. A slag collection well 6 is located between the lower end of the cylinder 1 and the slag discharge port 8. A valve (a flange butterfly valve is used in a specific embodiment) 7 is mounted on each end of the slag collection well 6. Online sludge discharge is achieved by sequentially opening the two valves on the slag collection well.

[0026] The filter screen 4 is a drawer-type filter screen, including a flange cover 10, a flange 11, a housing 12, and a filter screen assembly 13. The housing 12 is divided into an upper housing 14 and a lower housing 15 with identical structures. The upper housing 14 and the lower housing 15 have a U-shaped structure, and their outer rings are connected by a connecting plate 16, forming a space between the upper housing 14 and the lower housing 15 for placing the filter screen assembly 13. One end of the housing (the arc-shaped end of the upper housing 14 and the lower housing 15) has an assembly hole, and the other end is fixedly connected to the flange 11. The housing 12 is fitted onto the cylinder 1 through the assembly hole, and the housing and the cylinder are welded together. In the prior art, the filter screen of the cyclone separator is fixedly installed inside the cylinder and cannot be removed for cleaning. The filter screen of this application is a drawer-type filter screen, which allows the filter screen assembly to be pulled out for cleaning or replacement with a new filter screen or filter screen assembly.

[0027] The filter assembly 13 includes a support plate 18, a filter 19, a ring band 20, and a support rib 21. One end of the support plate 18 is flat, and the other end is an inwardly concave arc surface. The ring band 20 is fixedly connected to one end of the arc surface of the support plate 18. The support rib 21 is fixedly connected inside the ring band 20, and the filter 19 is mounted on the side of the support rib inside the ring band 20. There can be two support ribs, which are welded to the inside of the ring band. The filter is sandwiched between the two support ribs and welded to the ring band. The cylinder has a transverse elongated hole on its side wall. The filter assembly 13 is inserted into the cylinder 1 through the space between the upper shell 14 and the lower shell 15 and through the elongated hole on the cylinder. The flange cover 10 is fixedly connected to the flange 11, and the flange and flange cover are sealed by a sealing gasket. The support plate has two elongated holes 22. When the filter assembly needs to be removed, the flange cover is removed from the flange. The operator uses a hook to insert into the gap between the upper and lower housings and pulls out the filter assembly for cleaning or replacement through the elongated holes on the support plate.

[0028] The flushing port 5 is fitted with a flange, which is then locked in place by a blind flange. The filter screen is cleaned through the flushing port. The flange and the blind flange are sealed together by a gasket. Specific implementation examples:

[0030] This application relates to a sludge separator in the heating industry. It features a wastewater inlet pipe perpendicular to the cylinder's axis at the top of the cylinder body. Ideally, the inlet pipe is tangentially arranged to the cylinder's side wall, allowing fluid to enter the cylinder in a swirling motion, filling it with rotating water. The less dense, clear water rises and, after passing through a filter screen, flows out of the device through the outlet at the top of the cylinder. Solid particles and impurities in the water settle to the bottom due to gravity and enter a slag discharge well. Two valves are installed on the slag discharge well, allowing the system to remove sand and sludge without shutting down. During periodic maintenance, the valve at the bottom of the cyclone separator is opened to drain impurities. The system can discharge sludge without shutting down, making it suitable for cleaning solid impurities such as mud, stones, and pipe wall debris from pipelines. Of course, under certain conditions and within certain limits, multiple sludge separators can be used in series for even better results.

[0031] Work process:

[0032] Online sewage discharge:

[0033] 1. When the online cyclone separator of this application is in normal use, the upper flange butterfly valve is open, and sludge and other pollutants normally enter the slag discharge well;

[0034] 2. When sewage needs to be discharged, close the flange butterfly valve at the top of the slag discharge well to isolate the cylinder from the slag discharge well;

[0035] 3. Open the flange butterfly valve at the bottom of the slag discharge well to empty the sludge in the slag discharge well;

[0036] 4. Close the flange butterfly valve at the bottom of the slag discharge well;

[0037] 5. Open the flange butterfly valve at the top of the slag discharge well to connect the slag collection well with the cylinder and continue working.

[0038] Note: The valve used in the example is a flanged butterfly valve.

[0039] Replace the filter:

[0040] Wastewater flows upwards, undergoes secondary filtration through a drawer-type filter screen, and is discharged through the outlet pipe. The filter screen assembly is sealed inside the cylinder by flanges and a flange cover. When cleaning or replacing the filter screen is required, open the flange cover and use a long hook or similar tool to pull out the filter screen assembly through the elongated holes on the support plate for replacement or cleaning. The filter screen area to diameter ratio is relatively large; a coarser filter screen is selected during initial operation to prevent clogging and quickly remove larger particles. Subsequently, a smaller aperture filter screen is used according to operating conditions to meet requirements. The filter screen can be removed and replaced during maintenance.

[0041] Rinse the filter screen through the rinsing port:

[0042] Filters can become clogged over time, affecting filtration efficiency. The flushing port design allows for convenient and quick rinsing of the filter, saving time and effort, reducing downtime, and enabling rapid resumption of operation.

[0043] The filtration and decontamination process described in this application combines the principles of cyclone centrifugation with mechanical filter screen filtration, achieving excellent removal of solid particles and playing a vital role in water treatment for various circulating pipeline systems.

[0044] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art, inspired by this description, design similar structures and implementations to the above embodiments without departing from the technical essence of the present invention, such designs should fall within the protection scope of the present invention.
