Description

Technical Field

[0001] The invention relates to the technical field of cyclone sewage discharge and degassing, in particular to a cyclone sewage discharge and degassing tank. Background Art

[0002] At present, in the hot water systems of heating and air conditioning, it is necessary to install decontamination devices and degassing devices to remove gas, large floating particles and small sediment particles in hot water, thereby improving the service life of the tank body and pipelines of the cyclone degassing tank.

[0003] In the prior art, large floating particles in sewage are usually removed by filtering. Long-term filtering will cause debris to accumulate at the mesh opening of the filter. At this time, backwashing is required to discharge the debris accumulated on the filter to ensure normal filtration requirements. When backwashing, it is necessary to stop adding water to the tank body and use the drain pipe of the tank body to reversely add water to form backwashing. During the backwashing process, it is impossible to continue to discharge and degasify, which affects the overall efficiency of decontamination and degassing. Summary of the invention

[0004] The object of the present invention is to provide a cyclone type sewage degassing tank, which is equipped with a double pipeline system for sewage removal and degassing. Backwashing can still be performed during the sewage removal and degassing process, so that backwashing and sewage removal and degassing can be carried out simultaneously, thereby improving the efficiency and effect of sewage removal and degassing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cyclone-type sewage degassing tank, comprising a tank body with a columnar structure, a water outlet pipe and an exhaust valve arranged on the top of the tank body, the water outlet pipe extends into the interior of the tank body, and a tank bottom sewage pipe is arranged at the bottom of the tank body; two water inlet pipes are connected to the tank body, the water inlet directions of the two water inlet pipes are tangent to the circumference of the tank body, and the swirl directions formed by the water flows flowing into the tank body through the two water inlet pipes are opposite; filter screens are respectively arranged at the water outlets of the two water inlet pipes; a sewage pipe is connected to the two water inlet pipes; two water supply pipes are also connected to the tank body, the water inlet directions of the two water supply pipes are tangent to the circumference of the tank body, and the swirl directions formed by the water flows flowing into the tank body through the two water supply pipes are opposite;

[0006] The water inlet pipe, the sewage pipe, the water supply pipe and the sewage pipe at the bottom of the tank are respectively provided with valves.

[0007] Preferably, the two water inlet pipes are respectively arranged on the left and right sides of the tank body.

[0008] Preferably, the filter screen includes a filter screen plate and a screen frame arranged outside the filter screen plate.

[0009] Preferably, the water inlet ends of the two water inlet pipes are connected to the water inlet main pipe via a tee pipe.

[0010] Preferably, the drainage ends of the two sewage pipes are connected to the sewage main pipe through a three-way pipe.

[0011] Preferably, the water inlet ends of the two water supply pipes are connected via a water supply main pipe.

[0012] Preferably, it also includes legs arranged at the bottom of the tank body.

[0013] Preferably, a filter is provided in the water supply pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention uses a dual-pipe system to perform decontamination and degassing respectively. When the filter screen needs to be backwashed, the corresponding water inlet valve is closed and the drain valve is opened. At the same time, the other water inlet pipe is opened to continue to introduce water into the tank body for decontamination and degassing. In this way, the decontamination and degassing can be continuously carried out, and backwashing can be performed while the decontamination and degassing are performed, thereby improving the operation effect and efficiency of the decontamination and degassing.

[0016] 2. In the present invention, the filter screen is arranged in the water inlet pipe and close to the side wall of the tank body. The filter screen is located in the water inlet pipe to ensure that the water flow from the water inlet pipe into the tank body can stably form a vortex along the inner wall of the tank body without being affected by the filter screen, thereby improving the vortex formation effect.

[0017] 3. In the present invention, the water inlet ends of the two water inlet pipes are connected to the water inlet main pipe through a tee pipe, the discharge ends of the two sewage pipes are connected to the sewage main pipe through a tee pipe, and the water inlet ends of the two water replenishment pipes are connected through the water replenishment main pipe, which is convenient for the unified drainage of sewage and replenishment water, and the unified discharge of sewage after backwashing.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For the convenience of description, the coordinate system is defined as Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0037] like Figures 1 to 4As shown, a cyclone type sewage degassing tank comprises a tank body 1 with a columnar structure, and a water outlet pipe 6 and an exhaust valve 7 arranged on the top of the tank body 1, wherein the water outlet pipe 6 extends into the interior of the tank body 1, and a tank bottom sewage pipe 11 is arranged at the bottom of the tank body 1; two water inlet pipes are connected to the tank body 1, and the water inlet directions of the two water inlet pipes are tangent to the circumference of the tank body 1, and the swirl directions formed by the water flows flowing into the tank body 1 through the two water inlet pipes are opposite; filter screens are respectively arranged at the water outlets of the two water inlet pipes; sewage pipes are connected to the two water inlet pipes; two water supply pipes 41 are also connected to the tank body 1, and the water inlet directions of the two water supply pipes are tangent to the circumference of the tank body 1, and the swirl directions formed by the water flows flowing into the tank body 1 through the two water supply pipes are opposite.

[0038] The water inlet pipe, the sewage pipe, the water supply pipe and the tank bottom sewage pipe 11 are respectively provided with valves.

[0039] Preferably, in this embodiment, the two water inlet pipes are respectively arranged on the left and right sides of the tank body 1.

[0040] For the convenience of distinction and description, the two water inlet pipes are respectively water inlet pipe Ⅰ21 and water inlet pipe Ⅱ22, and the valves located on water inlet pipe Ⅰ21 and water inlet pipe Ⅱ22 are respectively water inlet valve Ⅰ23 and water inlet valve Ⅱ24; the sewage pipes connected to water inlet pipe Ⅰ21 and water inlet pipe Ⅱ22 are respectively sewage pipe Ⅰ31 and sewage pipe Ⅱ32, and the valves located on sewage pipe Ⅰ31 and sewage pipe Ⅱ32 are respectively sewage valve Ⅰ33 and sewage valve Ⅱ34; the two make-up water pipes are respectively make-up water pipe Ⅰ41 and water make-up water pipe Ⅱ42, and the valves located on make-up water pipe Ⅰ41 and water make-up water pipe Ⅱ42 are respectively make-up water valve Ⅰ43 and water make-up water valve Ⅱ44; the filters 5 corresponding to water inlet pipe Ⅰ21 and water inlet pipe Ⅱ22 are respectively filter mesh Ⅰ51 and filter mesh Ⅱ52.

[0041] like Figure 1 As shown, since the swirl directions formed by the water inlet pipe Ⅰ21 and the water inlet pipe Ⅱ22 flowing into the tank body 1 are opposite, and the swirl directions formed by the water replenishment pipe Ⅰ41 and the water replenishment pipe Ⅱ42 flowing into the tank body 1 are opposite, the swirl directions formed by the water inlet pipe Ⅰ21 and the water replenishment pipe Ⅰ41 flowing into the tank body 1 are the same, and the swirl directions formed by the water inlet pipe Ⅱ22 and the water replenishment pipe Ⅱ42 flowing into the tank body 1 are the same.

[0042] like Figure 8As shown, when backwashing is not performed, only one water inlet pipe needs to be introduced, and the example of introducing water into the water inlet pipe Ⅰ21 is as follows: at this time, the water inlet valve Ⅰ23 is opened, and all other valves are closed. The water flows through the water inlet pipe Ⅰ21 into the tank body 1, and forms a vortex under the guidance of the inner wall of the tank body 1. When the water flows through the filter screen Ⅰ51, the larger floating particles are filtered, and the fine heavy particles gather at the bottom of the tank body 1 under the action of the vortex. The center velocity of the vortex is close to zero, so that the air in the water is discharged smoothly, and the air is collected at the highest point through the outlet pipe 6, and then discharged by the exhaust valve 7. The decontaminated water finally flows out of the tank body 1 through the outlet pipe 6.

[0043] Similarly, only the water inlet valve II 24 may be opened to introduce water into the tank body 1 through the water inlet pipe II 22 , and the filter screen II 52 may be used to filter and remove dirt.

[0044] like Figure 7 As shown, long-term filtration will cause debris to accumulate at the mesh opening of the filter. At this time, backwashing is required to discharge the debris accumulated on the filter to ensure normal filtration requirements. When backwashing is required, take the need to backwash the filter Ⅱ52 as an example. At this time, open the water inlet valve Ⅰ23, the water replenishment valve Ⅰ43 and the sewage valve Ⅱ34, and all other valves are closed. The water flow through the water inlet pipe Ⅰ21 enters the interior of the tank body 1 and forms a vortex normally. Since the water inlet valve Ⅱ24 is closed and the sewage valve Ⅱ34 is opened at this time, the water flow inside the tank body 1 will form a flushing and backwashing of the filter Ⅱ52 when it flows through the filter Ⅱ52, and the debris accumulated at the filter opening of the filter Ⅱ52 is discharged through the sewage pipe Ⅱ32. Since the directions of the vortexes formed by the water inlet pipe Ⅰ21 and the water inlet pipe Ⅱ22 flowing into the tank body 1 are opposite, the direction of the water flow when the vortex formed by the water inlet pipe Ⅰ21 inside the tank body 1 flows into the filter screen Ⅱ52 is equivalent to the reverse direction of the water flow flowing into the tank body 1 from the water inlet pipe Ⅱ22. In this way, the water flow can directly impact the filter screen Ⅱ52, thereby ensuring the impact force of the water flow and improving the backwashing effect.

[0045] At the same time, water flow and water pressure are increased into the tank body 1 through the water supply pipe Ⅰ41, the water flow and water pressure are enhanced, the stable formation of vortex is ensured, the backwash intensity is improved, and the drainage water pressure at the outlet pipe 6 is ensured.

[0046] On the contrary, the filter screen I51 can be backwashed by opening the water inlet valve II24, the water supply valve II44 and the sewage valve I33 and closing all other valves.

[0047] To sum up, for the filter screen 5 that needs backwashing, its corresponding water inlet valve is closed and the drain valve is opened, and at the same time, another water inlet pipe is opened to continue to introduce water into the tank body 1 for decontamination and degassing. This can not only maintain the continuous decontamination and degassing, but also perform backwashing while decontamination and degassing, thereby improving the decontamination and degassing operation effect and efficiency.

[0048] The tank bottom drain pipe 11 is provided with a tank bottom drain valve 12. When heavy particle sediments need to be discharged from the bottom of the tank body 1, the tank bottom drain valve 12 can be opened to discharge the heavy particle sediments.

[0049] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Fig. 9 As shown, the filter 5 includes a filter plate 501 and a mesh frame 502 arranged on the outside of the filter plate 501, and the filter plate 501 and the mesh frame 502 are both arranged in an arc shape. The filter plate 501 and the mesh frame 502 are arranged in the water inlet pipe and close to the side wall of the tank body 1, so that the filter 5 is located in the water inlet pipe, ensuring that the water flow from the water inlet pipe into the tank body 1 can stably form a vortex along the inner wall of the tank body 1, ensuring that the formation of the vortex is not affected by the filter.

[0050] Furthermore, if Figure 1 and Figure 7 As shown, the water inlet ends of the two water inlet pipes are connected to the water inlet main pipe 25 through a tee pipe, the discharge ends of the two sewage pipes are connected to the sewage main pipe 35 through a tee pipe, and the water inlet ends of the two water replenishment pipes are connected through the water replenishment main pipe 45, which facilitates the unified drainage of sewage and replenishment water, and the unified discharge of sewage after backwashing.

[0051] It should be noted that the present embodiment also includes sewage pumps (not shown in the figure) respectively arranged on the water inlet main pipe 25 and the sewage discharge main pipe 35, and booster pumps respectively arranged on the water supply main pipe 45 and the water outlet pipe 6. The above-mentioned sewage pumps and booster pumps belong to the existing conventional technology, and their specific settings will not be described in detail here.

[0052] This embodiment also includes supporting legs 13 arranged at the bottom of the tank body 1 , and at least three supporting legs 13 are arranged to support the tank body 1 .

[0053] In this embodiment, a filter screen 5 is also provided in the water supply pipe, which can perform a filtering effect and form a protection for the pipe opening of the water supply pipe to reduce the influence of the vortex formation.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
