Description

Technical Field

[0001] The invention relates to the technical field of odor blocking, and in particular to an automatic siphon drainage type six-layer water-sealed aerosol odor blocking device. Background Art

[0002] Traditional bathroom odor-blocking and anti-pipeline aerosol sewer floor drains rely solely on a self-weight baffle to block sewer odor aerosol gases from entering the room, or some designs have only one or two water seal areas. The amount of water stored in the water seal areas is too small. When people are often not at home or do not flush the floor drains frequently, the water in the water seal areas of the sewer floor drains will naturally evaporate and dry up, failing to achieve the purpose of water sealing the sewer odor aerosol gases, which will bring aerosol risks to the bathroom.

[0003] In addition, the water traps of traditional bathrooms, kitchens and the bottom of each floor of residential buildings have relatively small water storage capacities. Some of the water traps have leakage that destroys the water seal effect. As a result, the longitudinally interconnected drainage pipes of the residents on the upper and lower floors of some residential buildings will have some residents using the toilet or kitchen to drain water. The gas circulation in the pipe network will instantly volatilize the odor or oily odor of kitchen washing sewage to the floor drains of other residents, so that the homes of the residents upstairs and downstairs of the entire building will be exposed to the risk of aerosols of some gases from the bathroom or kitchen of other households; in addition, traditional municipal sewers are all cylindrical or square manhole tanks. The odor generated by the mixture of sludge and sewage in the sludge pool at the bottom of the tank and the odor flowing in series of the entire pipe network all evaporate along the ventilation holes of the manhole cover to the vicinity of the road surface, making pedestrians passing by the manhole cover and residents or businesses living near the manhole cover unbearable. The grease trap is connected to the septic tank, so the risk of aerosols containing viruses and bacteria is even greater; the other is the high-level water tank in the traditional public toilet flushing. The water storage and flushing method relies on the floating ball of the float valve to float up and the floating ball to drop with its own weight to pull up or drop the drain valve core so that it can automatically flush when the automatic water storage volume is reached. The float valve in the traditional high-level water tank is a mechanical lever principle. After frequent use and fatigue, the sealing of the plug core is damaged, which affects the effect of water control and flushing. Sometimes some float valves or automatic drain tank mechanical automatic drainage devices are also affected by the water quality of the incoming water. The sand in the water or the dust accumulated in the opened high-level water tank or the cigarette butts and paper scraps thrown in by humans can get stuck in the float valve core or the automatic drain tank water inlet hole, seriously affecting the water inlet control, so that the high-level water tank is always filled with water at a low level. The half-empty state of the float causes the drain valve core to be not completely closed, and the automatic flushing within the set timing range corresponding to the set water storage volume cannot be achieved. Instead, the flushing water pressure is low, the flushing effect cannot be achieved, and a large amount of water is wasted. In addition, the urine odor still exists when flushing the traditional water-flush urinal, and the waterless urinal also has the odor-blocking mechanism. The single water-sealed water trap design or the diaphragm odor-blocking valve design is unreasonable. The waterless urinal cannot achieve long-term blocking of the urine odor of the urine of the toilet users. It cannot effectively block the urine odor and ammonia odor volatilized from the sewer pipe, which flows along the urinal drainage pipe and then flows from the urinal filter to the toilet space. The odor-blocking diaphragm valve body and valve core of some waterless urinals have a certain service life limit and require regular replacement. There are defects such as high management cost and high replacement cost, as well as poor sanitary odor-blocking effect. Therefore, we have developed a siphon drainage type six-layer water-sealed aerosol odor-blocking device to replace the above facilities, which can completely solve the risk of aerosol volatilization due to poor odor blocking. Specifically, it is an automatic siphon drainage type six-layer water-sealed aerosol odor-blocking device. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic siphon drainage type six-layer water-sealed aerosol odor blocking device, which can not only quickly control the discharge of sewage, but also block the aerosol odor gas in the sewer pipes and manhole sewers to prevent them from volatilizing to the outside, and block and isolate the pathogenic bacteria in the aerosol formed by the odor source, thereby avoiding the risk of aerosol pathogens spreading through pipelines.

[0005] To achieve the above object, the present invention provides the following technical solution: an automatic siphon drainage type six-layer water-sealed aerosol odor blocking device, comprising a box body, wherein a partition plate is provided inside the box body to separate the box body into a primary water-sealed area and a secondary water-sealed area;

[0006] The primary water seal area is provided with a water inlet pipe, and the water inlet pipe is inserted below the liquid level of the primary water seal area;

[0007] An inverted L-shaped diversion overflow pipe for connecting the primary water seal area and the secondary water seal area is provided at a certain height on the bottom of the bulkhead. The upper edge of the short pipe opening of one end of the inverted L-shaped diversion overflow pipe extending into the primary water seal area is located below the liquid surface, and the end extending into the secondary water seal area is located above the outlet of the water inlet pipe.

[0008] The secondary water seal area is provided with a drainage pipe.

[0009] Preferably, a siphon drainage elbow assembly is provided in the secondary water seal area;

[0010] The siphon drainage elbow assembly includes a siphon water inlet, a siphon elbow, and a siphon drainage pipe outlet;

[0011] The inlet height of the siphon water inlet is below the liquid level;

[0012] The height of the siphon elbow is adjustable, and both ends are connected to the siphon water inlet and the siphon drain pipe outlet respectively;

[0013] The outlet of the siphon drain pipe is located below the liquid level and is connected to an external drain pipe.

[0014] Preferably, an oil layer is provided on the liquid in the primary water seal area, and the water inlet pipe extends below the oil layer.

[0015] Preferably, the bulkhead is provided with a diversion water hole, and the inverted L-shaped diversion overflow pipe is installed on the diversion water hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention utilizes a middle partition plate to separate the interior of the box body (or tank body, or manhole) structure into two liquid level water seal areas. By installing and adjusting the height difference design of the diversion overflow pipe and the inlet and outlet pipe openings of the siphon drainage pipe, not only can the sewage discharge volume be controlled by artificial and planned design, but also the odorous gas in the sewer floor drain and the pipe network or manhole sewer can be blocked through multiple water seals and oil seals to prevent it from volatilizing to the outside, and the toxic and harmful aerosol pathogens formed by the odor source can be blocked and isolated, thereby avoiding the risk of aerosol pathogens spreading through the pipe.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, an automatic siphon drainage type six-layer water-sealed aerosol odor blocking device includes a box body 1 (or a pool body, or a manhole) that can flow and contain liquid. A partition board 2 is provided inside the box body 1 (or a pool body, or a manhole), and the interior of the box body 1 containing water is divided into a primary water seal area 3 and a secondary water seal area 4 by the partition board 2. A diversion water hole 5 is provided at a certain height at the bottom of the partition board 2 facing the primary water seal area 3 between the primary water seal area 3 and the secondary water seal area 4. An inverted L-shaped diversion overflow pipe 6 is connected with the diversion water hole 5 in the direction of the partition board of the secondary water seal area 4, and a siphon drainage elbow assembly 7 is installed in the secondary water seal area 4.

[0023] like Figure 1As shown, the water inlet pipe 9 is located in the upper left corner of the primary water seal area 3, and the bend of the water inlet pipe 9 extends below the sewage liquid level in the primary water seal area 3, the diversion water hole 5 and the inverted L-shaped diversion overflow pipe 6 are arranged at the lower part of the bulkhead 2, the upper edge of the short pipe opening at one end of the inverted L-shaped diversion overflow pipe 6 extending into the primary water seal area 3 is always located below the liquid level of the primary water seal area, and the overflow opening of the long pipe with one end facing upwards extending into the secondary water seal area 4 is always located above the outlet of the water inlet pipe 9; and the siphon bend 7.2 of the siphon drainage bend assembly 7 is slightly lower than the top of the inverted L-shaped diversion overflow pipe 6.

[0024] In this way, when the liquid in the primary water seal area 3 is higher than the top of the inverted L-shaped diversion overflow pipe 6, the sewage flows from the primary water seal area 3 into the secondary water seal area 4 through the inverted L-shaped diversion overflow pipe 6. When the liquid level in the primary water seal area 3 is lower than the top of the inverted L-shaped diversion overflow pipe 6, the sewage in the primary water seal area 3 is temporarily unable to overflow into the secondary water seal area.

[0025] When the liquid level in the secondary water seal area 4 exceeds the siphon elbow 7.2, the siphon drainage elbow assembly installed in the secondary water seal area 4 will produce a siphon effect and siphon the water to a level below the siphon inlet 7.1, where the air is siphoned, and the drainage will stop. Therefore, by adjusting the height of the siphon inlet 7.1 and the siphon elbow 7.2 of the siphon drainage elbow assembly, the liquid level and drainage volume at the start of drainage in the secondary water seal area 4 can be designed and controlled. By adjusting the height of the siphon inlet 7.1, the lowest liquid level in the secondary water seal area 4 after drainage can also be controlled.

[0026] The drainage outlet direction of the siphon drainage elbow assembly 7 can be on any side of the secondary water seal area 4 except one side of the bulkhead 2, or it can be set at the bottom of the secondary water seal area 4. The outlet pipe of the siphon drainage elbow protrudes from the outside of the secondary water seal box 1, and its pipe diameter corresponds to the diameter of its external pipe. Its external connection method can be a bayonet clamp docking, or a socket-and-spigot pipe glued docking, or a socket-and-spigot rubber ring docking, and a direct short pipe docking to ensure that the docking point of the external drainage pipe 8 does not leak or fall off.

[0027] The inlet pipe for odor-causing liquids or sewage can be installed on any side or top of the primary water seal area 3, excluding one side of the bulkhead 2, to meet the needs of different installation conditions. Furthermore, the siphonic six-layer water-sealing odor-blocking device can adjust the drainage volume by adjusting the water storage height of the siphon drainage elbow, and correspondingly adjust the drainage pressure, achieving a six-layer water seal to block the odor of the sewage source while simultaneously siphoning away large amounts of water quickly. Furthermore, the height of the siphon drainage elbow assembly 7 determines the water inlet level and the drainage volume. Water inlet control, corresponding to drainage time and drainage volume, does not require a float valve to control the water inlet.

[0028] For example, when modifying the high-level water tanks of traditional public toilets, the flushing facilities no longer use float valves and pull-wire levers to open and close the drain valve core to achieve automatic drainage. There are no defects such as mechanical failure of the float and easy clogging of the float valve core. This can more economically and efficiently meet the long-life use requirements of automatic drainage and flushing in public toilets.

[0029] When in use, the automatic siphon drainage six-layer water-sealed aerosol odor blocking device can be used to divide the interior of the water-containing box 1 (or tank body, or manhole) into a primary water-sealed area 3 and a secondary water-sealed area 4 through the partition board 2 provided inside the water-containing box 1 (or tank body, or manhole);

[0030] Since a diversion water hole 5 is provided at a certain height at the bottom facing the bulkhead 2 of the first water seal area 3 between the first water seal area 3 and the second water seal area 4, a leak-proof inverted L-shaped diversion overflow pipe 6 is installed with a fixed sealing socket connection corresponding to the diversion water hole 5 in the direction of the bulkhead 2 of the second water seal area 4. The drained sewage can only enter the second water seal area 4 from the diversion water hole 5 at the bottom of the first water seal area 3 along the inverted L-shaped diversion overflow pipe 6, limiting the sewage runoff path. At the same time, the top of the inverted L-shaped diversion overflow pipe 6 to the inner wall of the entire independent pipe always maintains an independent water level, which also plays a certain sealing effect. The inlet and outlet of this inverted L-shaped diversion overflow pipe 6 are always blocked by water, which is planned to be the third water seal and fourth water seal sealing areas.

[0031] Since the siphon drainage elbow assembly 7 is installed at the water outlet direction of the secondary water seal area 4, the direction of the drainage outlet pipe of the siphon drainage elbow assembly 7 can be on any side of the box body 1 (or pool body, or manhole) of the secondary water seal area 4 except the surface of the bulkhead 2 itself, and can also be set at the bottom of the box body 1 of the secondary water seal area 4.

[0032] The drainage outlet pipe socket of the siphon drainage elbow assembly 7 protrudes from the outside of the secondary water seal box 1, and its pipe diameter corresponds to the diameter of its external pipe. Its external connection method can be a bayonet clamp connection, or a socket-and-spigot pipe glue connection with large and small heads, or a socket-and-spigot rubber ring connection, and a direct short pipe connection to ensure that the connection point of the external drainage pipe 8 does not leak or fall off.

[0033] The water inlet pipe for the odor source liquid or sewage can be set in any side and top direction of the box body 1 except the bulkhead 2 itself in the first water seal area 3 to meet the needs of different installation conditions. At the same time, the elbow of the water inlet pipe is inserted below the water seal liquid level so that the end of the water inlet of the entire water inlet pipe is submerged by the water level and blocked, which also has a certain blocking effect. It is planned to be a fifth-level water seal blocking area. Even if the elbow of the water inlet pipe is not submerged by the liquid level of the first water seal area 3, a non-toxic, harmless, and pollution-free odor-blocking oil layer that can always float on the water surface can be placed on the liquid surface of the first water seal area 3 to enhance the fifth-level blocking and odor-blocking function, and the odor source aerosol below the blocking liquid level will evaporate to the outside along the water inlet pipe 9. When the liquid level of the first water seal area 3 does not submerge the water inlet pipe 9, the sewage odor and toxic and harmful aerosols in the first water seal area 3 will not evaporate along the empty pipe of the water inlet pipe 9.

[0034] The height of the siphon water inlet 7.1 of the siphon drainage elbow assembly 7 from the liquid level at the bottom of the box body 1 (or pool body, or manhole) and the height of the elbow position of the siphon drainage elbow assembly 7 can be adjusted according to the volume of the water sealing and odor-blocking facility itself and the reasonable height required for the blocking water volume. At the same time, the bottom of the siphon water inlet 7.1 to the inner wall of the entire independent siphon elbow 7.2 assembly is always kept sealed with water, which also has a certain blocking effect and is planned to be the sixth-level water seal blocking area.

[0035] The drainage volume and drainage pressure of the siphon drainage elbow assembly 7 can be controlled by adjusting the volume of the box body 1 (or the pool body, or the manhole) and the diameter of the internal siphon drainage elbow assembly 7 and the height of the assembly to achieve a six-layer water seal to block the odor of the sewage source while quickly and efficiently siphoning large amounts of water.

[0036] The present invention can not only be used to prevent odor and block floor drains, but can also replace traditional flush tanks controlled by mechanical float valves, achieving water inlet control corresponding to drainage time and drainage volume without the need for a mechanical float valve. For example, in the transformation of traditional public toilet pit-type flushing toilets, the high-level water tank no longer uses a float valve with a pull-wire lever to link the opening and closing of the drainage valve core to achieve automatic drainage. This eliminates the problems of mechanical failure of the float and easy clogging of the float valve core, thus more economically and efficiently meeting the long-life requirements of automatic drainage flushing in pit-type public toilets.

[0037] All components of the odor-blocking device can be made of carbon steel, stainless steel, fiberglass or plastic, and a primary slag interception filter is installed at the front end of the sewage water source entering the siphon drainage type six-layer water seal odor-blocking device.

[0038] The appearance and structure of the odor-blocking device can be changed arbitrarily. It can be a rectangular box, a square box, a cylindrical box, or a special-shaped structure box. Its core ensures that no matter what the appearance of the box 1 (or tank body, or manhole), whether it is installed in a floor drain or a sewer inspection well, or a water-flush urinal or a water-free urinal, and other facilities that need to block aerosol odors, the interior of the selected box 1 can be divided into a primary water seal area 3 and a secondary water seal area 4 through the bulkhead 2, and the diameter and height of the siphon drainage elbow assembly 7 and the water inlet pipe and the terminal drainage outlet pipe can be reasonably adjusted according to the different structural sizes and heights of the box 1 to meet the installation conditions of different water-sealed aerosol odor blocking.

[0039] When any sewage enters the device, regardless of its shape, the box body 1 (or pool body, or manhole) is divided into two areas by the designed middle partition plate 2. A certain amount of water is always guaranteed to exist in the pipes of the two areas, or the air flow is blocked by water when they are flooded, so that the sewage's own odor or the odor in the pipe network at the end of the water outlet will not evaporate into the water inlet pipe 9 and the open space of the water inlet pipe 9. A non-toxic and pollution-free oil sealing layer that can always float on the water surface can be added to the top of the water level in the first grid area. When the water inlet pipe 9 is not inserted below the first water level, the liquid level in the first-level water seal area 3 is low and the odor aerosol gas within the water surface can be sealed from evaporating along the water inlet pipe 9, thereby ensuring that the odor and toxic and harmful aerosol gas in the sewage pipe network sewer do not evaporate into the limited space indoors to damage the indoor air environment quality, thereby eliminating the risk of aerosol virus transmission.

[0040] The siphonic water seal and drainage method of the present invention can be extended to various products to block odors, prevent odors, and prevent aerosols from entering the room. For example, in traditional public toilets, high-level flushing tanks and existing trench flushing tanks all rely on the water inlet float lever to control the bottom valve to open and drain. This application does not require the use of a float.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
