Description

Technical Field

[0001] The utility model relates to the technical field of water supply pumps, in particular to a filtering device for water supply pumps. Background Art

[0002] The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. The boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. During use, the boiler needs a water pump to continuously supply water to it for heating.

[0003] After searching, a Chinese patent discloses a feed water pump for boiler water supply (authorization announcement number: CN 213775722U), including a motor, a mounting plate and a filter cartridge mechanism, the bottom surface of the mounting plate is provided with shock-absorbing pads on both sides, and the upper end surface of the mounting plate is fixed with a motor seat on the left side, and the motor is installed on the motor seat, the upper end surface of the mounting plate is fixed with a pump seat on the right side, and a water pump is installed on the pump seat, the mounting plate is installed with a mounting frame on the right side, and the filter cartridge mechanism is installed on the mounting frame, the left and right ends of the mounting frame are provided with support plates, and the bottom end of the support plate is fixed on the upper end surface of the mounting plate, the upper end surface of the water pump is provided with a water inlet end on the left side, and the upper end surface of the water pump is provided with a water outlet end on the right side, and the impeller shaft is rotatably connected in the water pump. The feed water pump for boiler water supply has a reasonable structure, which is convenient for multi-level filtration of tap water to remove tiny impurities, helps to reduce scaling inside the boiler and the water pump, and reduces the cost of later cleaning and maintenance.

[0004] In actual application, this patented technology can filter water, which helps to reduce scaling inside boilers and water pumps. However, during use, due to long-term filtering of the filter, impurities may clog the filter, so the filter needs to be cleaned and replaced regularly, and the above scheme is inconvenient to remove the filter for cleaning and replacement. At the same time, the above scheme increases the water supply pressure to the water pump by setting up a motor and an impeller shaft and other structures. Once the filter is clogged to a certain extent, the rotational resistance of the motor and the impeller shaft will increase, which will cause damage to the motor and the impeller shaft in the long run. At the same time, the insufficient pressure will also cause insufficient water supply to the water pump, causing damage to the water pump, and starting the motor also consumes electricity resources, thereby reducing the practicality of the device.

The water inlet pressure valve gauge 7 and the water outlet pressure valve gauge 8 are used to detect the water pressure at the input end and the output end of the filter box 4, and can also close the input end and the output end of the filter box 4. A card slot 9 is provided inside the filter box 4, and a filter screen 10 and a precision filter screen 11 are connected to the filter box 4 through the card slot 9. The card slot 9 is used to limit and fix the filter screen 10 and the precision filter screen 11;

[0026] The fixing mechanism 6 includes a fixed block 61, a rotating rod 62, a pull rod 63, a rotating block 64 and a handle 65. The fixed block 61 is fixedly connected to the top of the filter box 4, the rotating rod 62 is rotatably connected between the fixed block 61, the pull rod 63 is arranged above the rotating rod 62, one end of the pull rod 63 passes through the rotating rod 62 and is threadedly connected thereto, the rotating block 64 is movably connected to an upper corner of the cover plate 5, the other end of the rotating block 64 is rotatably connected to the rotating block 64, and the handle 65 is fixedly connected to one side of the rotating block 64.

[0027] Through the above technical solution, by setting a fixing mechanism 6, the handle 65 is pulled to drive the rotating block 64 to flip, and the handle 65 is turned to drive the rotating block 64 to rotate. The length of the pull rod 63 between the rotating rod 62 and the cover plate 5 is determined in the above manner. At this time, the rotating block 64 is rotated around the connection between the pull rod 63 and the rotating rod 62, so that the rotating block 64 can be detached from the cover plate 5, so that the cover plate 5 can be removed from the filter box 4 to clean and replace the filter screen inside the filter box 4.

[0028] Specifically, a sewage pipe 12 is provided below one side of the filter box 4 , one end of the sewage pipe 12 passes through the filter box 4 and is connected thereto, a control valve 13 is sleeved on the sewage pipe 12 , and the control valve 13 is fixedly connected to the sewage pipe 12 .

[0029] Through the above technical solution, by setting the sewage pipe 12 and the control valve 13 and opening the control valve 13, the sewage after cleaning can be discharged from the sewage pipe 12.

[0030] Specifically, a sealing gasket 14 is provided between the filter box 4 and the cover plate 5 , and the sealing gasket 14 is embedded in the upper inner wall of the filter box 4 .

[0031] Through the above technical solution, by providing the sealing gasket 14, the sealing effect between the filter box 4 and the cover plate 5 can be increased, and water leakage from between the filter box 4 and the cover plate 5 can be prevented.

[0032] Specifically, a liquid level observation window 15 is provided on one side of the water storage tank 3 , and the liquid level observation window 15 is fixedly connected to the inner wall of the water storage tank 3 .

[0033] Through the above technical solution, by setting the liquid level observation window 15, the liquid level of the clean water inside the water storage tank 3 can be effectively observed. When the liquid level is low, the input end of the filter box 4 can be opened in time through the water inlet pressure valve table 7. At the same time, when the liquid level is low, the water pump 2 can also be closed in time to prevent the water pump 2 from failing to pump water, causing damage to the water pump 2 itself.

[0034] Specifically, the pull rod 63 and the rotating block 64 are arranged to be eccentrically connected, and the lower part of the other side of the rotating block 64 is arranged to be an arc surface.

[0035] Through the above technical solution, by setting an eccentric connection between the pull rod 63 and the rotating block 64, the distance between the pull rod 63 and the rotating rod 62 and the cover plate 5 can be shortened. When the handle 65 is pressed, the rotating block 64 and the pull rod 63 cooperate to make the rotating block 64 and the cover plate 5 conflict with each other, thereby firmly fixing the cover plate 5 on the filter box 4. By setting an arc surface at the bottom of the other side of the rotating block 64, since the arc surface has guiding and flow-conducting properties, the staff can easily flip the rotating block 64.

[0036] Specifically, the filter box 4 is made of a high-strength injection-molded transparent material, and four fixing mechanisms 6 are arranged on the filter box 4 . The four fixing mechanisms 6 are arranged diagonally.

[0037] Through the above technical scheme, by setting the filter box 4 to be a high-strength injection-molded transparent material, the staff can observe the dirtiness of the filter screen inside the filter box 4, which is convenient for timely cleaning and replacement. By setting four fixing mechanisms 6 on the filter box 4, the cover plate 5 can be firmly fixed on the filter box 4, and the four fixing mechanisms 6 are diagonally arranged, so that the four fixing mechanisms 6 can have the same fixed resistance to the cover plate 5, thereby preventing a corner of the cover plate 5 from tilting due to different forces, causing water leakage.

[0038] Working principle: first, connect the input end of the filter box 4 to the tap water pipe. Impurities in the water can be filtered through the internal filter screen 10 and the precision filter screen 11 of the filter box 4. Then, the filtered water will flow into the interior of the water storage tank 3, realizing the pretreatment of the water. The filtered water is input into the water storage tank 3 for standby use, so as to facilitate the subsequent use of the water supply pump 2. At this time, there is no need to set up structures such as the motor and the impeller shaft, and the water supply pressure of the water supply pump 2 can also be guaranteed. In this way, the tap water can be pretreated and reserved before, after or when the water supply pump is used each time. At the same time, the staff can observe the liquid level observation window 15 on the water storage tank 3 to know the liquid level of the water inside the water storage tank 3 so as to timely pass the water inlet pressure. The valve table 7 closes the input of the filter box 4. When it is necessary to clean and replace the filter screen 10 and the precision filter screen 11 inside the filter box 4, the handle 65 can be pulled to drive the rotating block 64 to flip over, and the handle 65 can be turned to drive the rotating block 64 to rotate. The above method is used to rotate the length of the pull rod 63 between the rotating rod 62 and the cover plate 5, and then the rotating block 64 is rotated around the connection between the pull rod 63 and the rotating rod 62 to separate the rotating block 64 from the cover plate 5. In this way, the cover plate 5 can be removed from the filter box 4 to clean and replace the filter screen inside the filter box 4. At the same time, the staff can also use clean water to clean the inner wall of the filter box 4, and discharge the cleaned sewage from the sewage pipe 12 by opening the control valve 13.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
