Description

Technical Field

[0001] The invention relates to the technical field of floor drains, in particular to a steam-water double-sealed clean floor drain. Background Art

[0002] Floor drain is a drainage facility installed on the ground, mainly used for drainage in wet areas such as bathrooms, kitchens, and laundry rooms. As an important interface between the drainage pipe system and the indoor floor, it directly affects the quality of indoor air, especially plays an important role in odor control in bathrooms. The floor drains currently on the market have the following problems when used in pharmaceutical factories: the existing floor drains in pharmaceutical factories cannot prevent odors, microorganisms, bacteria, insects, mosquitoes and flies in the drainage pipes and air in the sewer pipes from entering the clean area, affecting the cleanliness quality of the clean area; For this reason, a soda-water double-seal clean floor drain is proposed. Summary of the invention

[0003] The object of the present invention is to provide a steam-water double-sealed clean floor drain to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a double-sealed clean floor drain for steam and water, comprising a mounting seat, a drain pipe, and a filter buckle cover, wherein the top of the drain pipe is fixedly connected to the bottom surface of the mounting seat, the filter buckle cover is located at the top of the mounting seat, a sleeve penetrating into the drain pipe cavity is inserted into the bottom surface of the inner wall of the mounting seat, a center pipe is fixedly connected to the inner wall of the top opening of the sleeve, a float is arranged between the bottom end of the center pipe and the inner wall of the bottom end of the sleeve, a circumferentially distributed through holes are opened on the outer surface of the sleeve, and the through holes are higher than the bottom opening of the center pipe, a cleaning component is arranged on the inner wall of the center pipe, and the top of the sleeve protrudes The bottom surface of the inner wall of the mounting base is detachably connected with a deflector cover, and the bottom surface of the deflector cover is provided with a deflection hole connected to the central pipe. Water is retained between the sewer pipe and the sleeve, and between the sleeve and the through hole, forming a double liquid seal, double insurance, and strictly blocking the escape of sewer odor and harmful gases. At the same time, the water in the sleeve lifts the float, allowing the float to accurately fit the outer bell mouth at the bottom of the central pipe, further strengthening the sealing effect and creating fresh air in all directions. When the deflector cover is pulled up, the scraper in the cleaning component rises and cleans along the inner wall of the central pipe to remove impurities and prevent dirt from hanging on the pipe wall to produce odor. This cleaning method can always maintain a good drainage state of the floor drain.

[0005] Preferably, the cleaning assembly includes a first filter plate, a second filter plate, and a scraper. The bottom surface of the second filter plate is flush with the top of the float in a floating state. The first filter plate is located above the second filter plate. The scrapers are distributed in a circle on the outer wall of the second filter plate. The edge of the scraper is close to the inner wall of the center tube. After the sewage flows down to the inner wall of the center tube through the diversion hole, it passes through the first filter plate and the second filter plate in turn for double filtration. At this time, the edge of the scraper can seal the inner wall of the center tube to prevent fine impurities from falling from the inner wall of the center tube.

[0006] Preferably, the central tube is trumpet-shaped at both ends and cylindrical in the middle, the inner wall of the guide hole is fixedly connected with a stabilizing column, the bottom surface of the stabilizing column is fixedly connected with a connecting rod, the bottom end of the connecting rod is fixedly connected to the top surface of the first filter plate, and a supporting rod is fixedly connected between the first filter plate and the second filter plate. When cleaning the inner wall of the central tube, the guide cover is directly pulled up, and then the first filter plate, the second filter plate and the scraper can be lifted up synchronously, and then the edge of the scraper and the surface of the first filter plate and the second filter plate can be cleaned to keep the device in a clean state for repeated use, thereby further avoiding the odor from being reflected upward.

[0007] Preferably, the scraper is distributed in a split shape on the outer wall of the second filter plate, and the outer wall of the second filter plate is provided with circumferentially distributed storage holes. A multi-section telescopic rod is arranged between the inner wall of each storage hole and the scraper, and a spring is connected between each section of the multi-section telescopic rod. The maximum outer diameter of the scraper is consistent with the top of the center tube. When the air deflector is pulled upward, the scraper is connected to the structure of the multi-section telescopic rod and the spring, and can expand with the change of the inner diameter of the different center tubes, thereby ensuring that the edge of the scraper can always contact the inner wall of the center tube. Since the scraper is distributed in a circle outside the second filter plate, it can be rotated and pulled up when moving upward to keep the inner wall of the center tube fully scraped.

[0008] Preferably, a clamping plate is fixedly connected to the top of the sleeve, and the diameter of the clamping plate is larger than the diameter of the sleeve, so that the sleeve can be conveniently inserted directly into the part where the top of the sewer pipe is connected to the mounting seat, which is convenient for removal and cleaning.

[0009] Preferably, the bottom surface of the deflector is provided with a snap-in slot that fits with a card plate, the outer wall of the card plate is evenly provided with protrusions, and the inner wall of the snap-in slot is provided with a recess that engages with the protrusions. This structural arrangement can maintain the stability of the deflector when receiving downstream water and avoid water flushing rotation.

[0010] Preferably, the top and bottom ends of the guide cover are in a cone shape with one end larger than the other, so as to conveniently receive sewage flowing down from the filter buckle cover.

[0011] Preferably, water is normally provided between the sleeve and the through hole and between the sleeve and the downcomer, which can realize double liquid sealing on the one hand, and the water in the sleeve space can make the float rise and contact the outer bell mouth at the lower part of the center pipe to realize sealing on the other hand.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By arranging water storage in the space between the downpipe and the casing and in the space between the casing and the through hole, on the one hand, double liquid sealing can be achieved, and on the other hand, the water in the casing space can make the float rise and contact with the outer bell mouth at the bottom of the central tube to achieve sealing. In addition, the arrangement of the cleaning component can make the scraper rise during the process of pulling up the deflector cover, and then clean the inner wall of the central tube to avoid impurities hanging on the wall and causing odor to be reflected upward from the central tube. In addition, the arrangement of the first filter plate and the second filter plate in the cleaning component can make the sewage double filtered when it is discharged from the device, which improves the filtering and discharge effect on the one hand, and cleans the surfaces of the first filter plate and the second filter plate when the cleaning component is removed on the other hand, thereby improving the cleaning efficiency of the device when it is reused.

[0015] 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.

[0016] See also Figures 1 to 6 , is an embodiment provided by the present invention: a steam-water double-seal clean floor drain, comprising a mounting seat 1, a downpipe 2, and a filter buckle cover 3. The top of the downpipe 2 is fixedly connected to the bottom surface of the mounting seat 1, and the filter buckle cover 3 is located at the top of the mounting seat 1. A sleeve 4 that penetrates into the cavity of the downpipe 2 is inserted on the bottom surface of the inner wall of the mounting seat 1. A center pipe 5 is fixedly connected to the inner wall of the top opening of the sleeve 4. A float 6 is arranged between the bottom end of the center pipe 5 and the inner wall of the bottom end of the sleeve 4. A circumferentially distributed through hole 7 is opened on the outer surface of the sleeve 4, and the through hole 7 is higher than the bottom opening of the center pipe 5. A cleaning component is arranged on the inner wall of the center pipe 5. The top end of the sleeve 4 extends out of the bottom surface of the inner wall of the mounting seat 1 and is detachably connected to a guide cover 8. The bottom surface of the guide cover 8 is provided with a guide hole 9 that communicates with the center pipe 5.

[0017] Among them, welding can be used between the sleeve 4 and the center tube 5, and the float 6 can move up and down between the lower part of the center tube 5 and the bottom of the sleeve 4. The float 6 is hollow in the middle and is made of stainless steel or high-temperature resistant plastic. The surface of the stainless steel is smooth and can achieve self-sealing after contacting the center tube 5.

[0018] Water is retained between the sewer pipe 2 and the sleeve 4, and between the sleeve 4 and the through hole 7, forming a double-liquid seal and double insurance, which can strictly block the escape of sewer odor and harmful gases. At the same time, the water in the sleeve 4 lifts the float 6, allowing the float 6 to accurately fit the outer bell mouth at the bottom of the center pipe 5, further strengthening the sealing effect and creating fresh air in all directions. When the deflector 8 is pulled up, the scraper 12 in the cleaning component rises and cleans along the inner wall of the center pipe 5 to remove impurities and prevent dirt from hanging on the pipe wall to produce odor. This cleaning method can always maintain a good drainage state of the floor drain.

[0019] like Figure 3-Figure 4 As shown, the cleaning assembly includes a first filter plate 10, a second filter plate 11, and a scraper 12. The bottom surface of the second filter plate 11 is flush with the top of the float 6 in the floating state. The first filter plate 10 is located above the second filter plate 11. The scrapers 12 are distributed in a circle on the outer wall of the second filter plate 11. The edge of the scraper 12 is close to the inner wall of the central tube 5. After the sewage flows down to the inner wall of the central tube 5 through the diversion hole 9, it passes through the first filter plate 10 and the second filter plate 11 in turn for double filtration. At this time, the edge of the scraper 12 can seal the inner wall of the central tube 5 to prevent fine impurities from falling from the inner wall of the central tube 5.

[0020] By setting the first filter plate 10 and the second filter plate 11, the sewage needs to pass through these two filter plates in sequence for filtration when flowing through, which can more effectively intercept impurities of different particle sizes. Compared with filtration by a single filter plate, the ability to remove impurities in sewage is greatly improved, making the treated water purer, reducing the pressure of subsequent treatment links, and being more conducive to meeting the water quality requirements for subsequent use or discharge. The bottom surface of the second filter plate 11 is flush with the top of the float 6 in the floating state, and the first filter plate 10 is located above the second filter plate 11. Such a position layout is in line with the natural downward flow trend of sewage, and can guide the sewage to pass through the two filter plates in an orderly manner, making full use of the sewage's own gravity, making the filtration process smoother and more efficient, and avoiding the situation where the sewage cannot be fully filtered due to unreasonable layout or water flow turbulence occurs, which affects the filtration effect.

[0021] like Figure 2-Figure 3 As shown, the central tube 5 is trumpet-shaped at both ends and cylindrical in the middle, and the outer diameter of 6 is larger than the diameter of the cylinder. The inner wall of the guide hole 9 is fixedly connected with a stabilizing column 18, and the bottom surface of the stabilizing column 18 is fixedly connected with a connecting rod 17. The bottom end of the connecting rod 17 is fixedly connected to the top surface of the first filter plate 10, and a supporting rod 16 is fixedly connected between the first filter plate 10 and the second filter plate 11. When cleaning the inner wall of the central tube 5, the guide cover 8 is directly pulled up, and then the first filter plate 10, the second filter plate 11, and the scraper 12 can be lifted up synchronously, and then the edge of the scraper 12 and the surface of the first filter plate 10 and the second filter plate 11 can be cleaned to keep the clean state of the device for repeated use, thereby further avoiding the odor from being reflected upward.

[0022] The central tube 5 is designed with trumpet-shaped ends and a cylindrical middle. The trumpet-shaped structures at both ends can play a role similar to diversion, allowing sewage to enter the central tube 5 more smoothly for treatment. At the same time, the treated water can flow out more evenly, reducing water flow resistance and local water accumulation that may be caused by poor water flow, thereby ensuring the smooth flow of water in the entire treatment process.

[0023] like Figure 3-Figure 5As shown, the scraper 12 is distributed in a split shape on the outer wall of the second filter plate 11. The outer wall of the second filter plate 11 is provided with circumferentially distributed receiving holes 13. A multi-section telescopic rod 14 is arranged between the inner wall of each receiving hole 13 and the scraper 12. A spring 15 is connected between each section of the multi-section telescopic rod 14. The maximum outer diameter of the scraper 12 is consistent with the top of the central tube 5. When the air deflector 8 is pulled upward, the scraper 12 is connected through the structure of the multi-section telescopic rod 14 and the spring 15, and can expand according to the change of the inner diameter of the different central tubes 5, thereby ensuring that the edge of the scraper 12 can always contact the inner wall of the central tube 5. Since the scraper 12 is distributed in a circle outside the second filter plate 11, it can be rotated and pulled up when moving upward to keep the inner wall of the central tube 5 fully scraped.

[0024] The scraper 12 is connected to the spring 15 through a multi-section telescopic rod 14, and can expand accordingly according to the change of the inner diameter of the central tube 5. This design ensures that the scraper 12 can still ensure that its edge is in close contact with the inner wall of the central tube 5 when passing through parts of the central tube 5 with different inner diameters. The scraper 12 is distributed circumferentially outside the second filter plate 11 and can be rotated and pulled up when moving upward. This rotating scraping method can cover all directions of the inner wall of the central tube 5, avoiding the occurrence of scraping dead corners.

[0025] like Figure 2 and Figure 6 As shown, a clamping plate 20 is fixedly connected to the top of the sleeve 4, and the diameter of the clamping plate 20 is larger than the diameter of the sleeve 4, so that the sleeve 4 can be conveniently inserted directly into the part where the top of the sewer pipe 2 is connected to the mounting seat 1, so as to facilitate dismantling and cleaning.

[0026] The clamping plate 20 arranged at the top of the sleeve 4 has a diameter larger than the diameter of the sleeve 4 itself. Such a structural design enables the sleeve 4 to be directly inserted into the part where the sleeve 4 is connected to the top of the sewer pipe 2 and the mounting seat 1 when being installed. Compared with those installation methods that require complicated connection operations, the use of numerous tools or precise alignment, this simple insertion method greatly reduces the difficulty of installation, saves installation time and labor costs.

[0027] like Figure 2 and Figure 6 As shown, the bottom surface of the air deflector 8 is provided with a snap-in socket 19 which fits with the card plate 20, the outer wall of the card plate 20 is evenly distributed with protrusions 21, and the inner wall of the snap-in socket 19 is provided with a recess 22 which engages with the protrusion 21. This structural setting can keep the air deflector 8 stable when receiving downstream water and avoid water flushing rotation.

[0028] The clamping structure tightly connects the air deflector 8 and the clamping plate 20 together, thereby making the air deflector 8 and related components such as the sleeve 4 form a more stable overall structure.

[0029] like Figure 2-Figure 3 As shown, the top and bottom ends of the flow guide cover 8 are in a cone shape with one end larger than the other, so as to conveniently receive the sewage flowing down from the filter buckle cover 3.

[0030] The guide cover 8 is conical between the top and the bottom, with one end larger than the other. When the larger end is placed upward, it can effectively increase the opening area at the top, thereby increasing the receiving range of sewage flowing down from the filter buckle cover 3. Compared with the ordinary cover structure of the same diameter, the conical guide cover 8 can capture sewage flowing down in a wider area, reducing the situation where sewage splashes out due to not being caught or cannot smoothly enter the subsequent treatment process, thereby improving the comprehensiveness and efficiency of sewage collection.

[0031] In this embodiment, water is normally provided between the sleeve 4 and the through hole 7 and between the sleeve 4 and the sewer pipe 2. On the one hand, double liquid sealing can be achieved. On the other hand, the water in the space of the sleeve 4 can make the float 6 rise and contact the outer bell mouth at the bottom of the center pipe 5 to achieve sealing.

[0032] The working steps are as follows: sewage flows in from the filter buckle cover 3 and enters along the top of the conical guide cover 8. The design of the guide cover 8 with a large top and a small bottom is convenient for receiving sewage. The sewage then flows into the central tube 5 through the guide hole 9 on the bottom of the guide cover 8. In this process, since the guide cover 8 is connected with the protrusion 21 and the recess 22 on the top card plate 20 of the sleeve 4 through the bottom card slot 19, it can maintain a stable reception of downstream water to avoid water flushing and rotation. After that, after the sewage enters the central tube 5, it passes through the first filter plate 10 and the second filter plate 11 in the cleaning component in turn to achieve double filtration. These two filtration The process can improve the filtering and discharge effect and intercept impurities in the sewage. At this time, the scraper 12 circumferentially distributed on the outer wall of the second filter plate 11, with its edge close to the inner wall of the central tube 5, can prevent fine impurities from falling from the inner wall of the central tube 5. The filtered sewage continues to flow down, through the through hole 7 on the outer surface of the sleeve 4, and finally discharged into the sewer 2. Since there is water between the sleeve 4 and the through hole 7 and between the sleeve 4 and the sewer 2 under normal conditions, a double liquid seal is formed to prevent the sewer odor from returning; at the same time, the water in the sleeve 4 causes the float 6 to rise and contact with the outer bell mouth at the bottom of the central tube 5, thereby enhancing the sealing effect; During regular cleaning, the deflector 8 is pulled up, and the deflector 8 is connected to the first filter plate 10 through the stabilizing column 18 and the connecting rod 17, so that the first filter plate 10, the second filter plate 11, and the scraper 12 are synchronously lifted up. The scraper 12 can automatically expand according to the change of the inner diameter of the central tube 5 through the structure of the multi-section telescopic rod 14 and the spring 15, ensuring that the edge of the scraper 12 is always in contact with the inner wall of the central tube 5, and the scraper 12 is distributed in a circle and can be rotated and pulled up when moving upward, so as to fully scrape the inner wall of the central tube 5, clean the impurities hanging on the wall, and prevent the odor from being reflected upward from the central tube 5. After pulling out the cleaning component, the surfaces of the first filter plate 10 and the second filter plate 11 can also be cleaned, and then the deflector 8 and other components can be reinstalled to keep the device clean and efficient for repeated use. When deep cleaning is required, the card plate 20 fixed at the top of the sleeve 4 can be used to conveniently remove the sleeve 4 from the connection part between the top of the sewer pipe 2 and the mounting seat 1 for more comprehensive cleaning work.
