Description

Technical Field

[0001] This utility model belongs to the field of filtration equipment technology, specifically relating to a filtration device for an engineering water supply circulation system. Background Technology

[0002] During construction, water consumption is high for projects such as atomized spraying for dust suppression and greening irrigation. In order to reduce water waste during construction, some wastewater used during construction can be recycled, treated, and reused to achieve water recycling and reduce water waste. Filtration equipment is an essential part of the water supply recycling system.

[0003] In existing water supply circulation system filtration equipment, the recycled circulating water is directly injected into the filtration equipment for filtration. This results in a large flow of circulating water directly contacting the filter element, which generates a large impact force on the filter element, thereby affecting the service life of the filter element and the filtration effect. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for an engineering water supply circulation system, which can depressurize and buffer the circulating water entering the filtration device to prevent high-pressure circulating water from directly contacting the filter element and causing damage to the filter element, thus affecting its filtration effect.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A filtration device for an engineering water supply circulation system includes a tank body. A support ring is fixedly installed on the upper side of the inner wall of the tank body. The upper surface of the support ring overlaps with the bottom surface of a buffer plate. The upper surface of the buffer plate is fixedly connected to the bottom surfaces of a barrier ring and an overflow ring. A water injection hole is opened in the middle of the buffer plate. The water injection hole is sleeved inside the overflow ring. A filter screen is fixedly installed at the upper end of the overflow ring.

[0007] Both the support ring and the buffer plate are provided with multiple screw holes, and two corresponding screw holes are threaded to the same screw.

[0008] The upper surface of the filter screen overlaps with the bottom surface of the scraper, and the end of the scraper is fixedly connected to the outer side of the rotating shaft.

[0009] The rotating shaft is rotatably connected to the upper end of the cover plate via a bearing, and the top end of the rotating shaft is fixedly connected to the motor output shaft.

[0010] The motor is fixedly connected to the cover plate via a mounting base, and the cover plate is fitted onto the top of the barrel.

[0011] A water inlet pipe is fixedly installed at the upper end of the cover plate, and the front and rear ends of the inner side of the cover plate are respectively fixedly connected to the opposite ends of the two limiting plates.

[0012] The opposite ends of the two limiting plates are respectively inserted into two limiting grooves, and both limiting grooves are opened on the outer side of the barrel.

[0013] The inner wall of the barrel is also fixedly connected to fixed plate one and fixed plate two, and fixed plate two has multiple sleeve holes.

[0014] The multiple sleeve holes are respectively sleeved with the bottom ends of multiple filter cylinders, and filter elements are fixedly installed inside the multiple filter cylinders. Each filter cylinder has a threaded groove on the upper end of its outer side surface and is threadedly connected to a screw hole.

[0015] Multiple screw holes are formed inside the fixed plate. Each filter cylinder is fixedly provided with a handle at the top and a drain pipe is fixedly provided at the bottom of the barrel.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention features a buffer plate at the top of the tank, with a barrier ring and an overflow ring on the buffer plate. When filtering circulating water using this device, circulating water is injected into the tank through the inlet pipe. The water to be filtered falls onto the buffer plate between the overflow ring and the barrier ring. As the water volume on the buffer plate increases and overflows through the overflow ring, the circulating water flows through the water inlet to the fixed plate. Thus, the cooperation of the buffer plate and the overflow ring buffers the pressure of the circulating water injected into the tank, preventing large-flow circulating water from directly contacting the filter element and impacting its lifespan and filtration effect.

[0018] This invention features a filter screen installed at the upper end of the overflow ring, along with a scraper that contacts the filter screen. When the circulating water on the buffer plate is discharged through the overflow ring and water inlet, the filter screen filters out large-volume impurities in the circulating water, thus preventing large-volume impurities from contacting and covering the filter element surface and affecting the filter element's filtration efficiency. Furthermore, the motor drives the rotating shaft and scraper to rotate, scraping off impurities from the filter screen surface so that the impurities fall onto the buffer plate, thereby effectively ensuring the filter screen's filtration efficiency.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5 As shown, a filtration device for an engineering water supply circulation system includes a tank 1. A support ring 14 is fixedly installed on the upper side of the inner wall of the tank 1. The upper surface of the support ring 14 overlaps with the bottom surface of the buffer plate 7. The upper surface of the buffer plate 7 is also fixedly connected to the bottom surfaces of the barrier ring 6 and the overflow ring 19. A water injection hole 20 is opened in the middle of the buffer plate 7. The water injection hole 20 is sleeved inside the overflow ring 19. A filter screen 21 is fixedly installed at the upper end of the overflow ring 19. By installing the filter screen 21 at the upper end of the overflow ring 19, when the circulating water on the buffer plate 7 is discharged through the overflow ring 19 and the water injection hole 20, the filter screen 21 filters and removes large-volume impurities in the circulating water, thereby preventing large-volume impurities from contacting the filter element 10 and covering the surface of the filter element 10, thus affecting the filtration efficiency of the filter element 10.

[0028] Furthermore, both the support ring 14 and the buffer plate 7 are provided with multiple screw holes 23, and two corresponding screw holes 23 are threadedly connected to the same screw 22.

[0029] Furthermore, the upper surface of the filter screen 21 overlaps with the bottom surface of the scraper 16, and the end of the scraper 16 is fixedly connected to the outer side of the rotating shaft 17.

[0030] Furthermore, the rotating shaft 17 is rotatably connected to the upper end of the cover plate 3 via a bearing, and the top end of the rotating shaft 17 is fixedly connected to the output shaft of the motor 5. By setting a scraper 16 on the rotating shaft 17 to contact the filter screen 21, and connecting the rotating shaft 17 to the output shaft of the motor 5, the motor 5 drives the rotating shaft 17 and the scraper 16 to rotate, scraping off the impurities on the surface of the filter screen 21 so that the impurities fall onto the buffer plate 7, thereby effectively ensuring the filtration efficiency of the filter screen 21.

[0031] Furthermore, the motor 5 is fixedly connected to the cover plate 3 via a mounting base, and the cover plate 3 is fitted onto the top of the barrel body 1.

[0032] Furthermore, a water inlet pipe 4 is fixedly installed at the upper end of the cover plate 3, and the front and rear ends of the inner side of the cover plate 3 are respectively fixedly connected to the opposite ends of the two limiting plates 18.

[0033] Furthermore, the opposite ends of the two limiting plates 18 are respectively inserted into the two limiting grooves 15. Both limiting grooves 15 are opened on the outer side of the barrel body 1. By setting the limiting plate 18 on the inner side of the cover plate 3 and opening the limiting groove 15 on the barrel body 1 to be inserted into the limiting plate 18, the limiting plate 3 is limited and fixed by the insertion of the limiting plate 18 and the limiting groove 15, which effectively improves the stability of the cover plate 3 and the motor 5.

[0034] Furthermore, the inner wall of the barrel 1 is also fixedly connected to the first fixed plate 8 and the second fixed plate 11, and the second fixed plate 11 has multiple sleeve holes 12.

[0035] Furthermore, multiple sleeve holes 12 are respectively sleeved with the bottom ends of multiple filter cylinders 9, and filter elements 10 are fixedly installed inside multiple filter cylinders 9. Each filter cylinder 9 has a threaded groove on the upper end of its outer side surface that is threadedly connected to a screw hole 13.

[0036] Furthermore, multiple screw holes 13 are opened inside the fixed plate 8, a handle is fixedly installed at the upper end of each filter cylinder 9, and a drain pipe 2 is fixedly installed at the bottom of the barrel 1.

[0037] The working principle of this utility model is as follows: When using this device to filter circulating water, the circulating water can be injected into the tank 1 through the water inlet pipe 4. At this time, the water to be filtered falls on the buffer plate 7 between the overflow ring 19 and the barrier ring 6. As the water volume on the buffer plate 7 increases and overflows through the overflow ring 19, the circulating water flows to the fixed plate 8 through the water injection hole 20. When the circulating water on the buffer plate 7 is discharged through the overflow ring 19 and the water injection hole 20, the filter screen 21 is used to filter and remove large volume impurities in the circulating water. In addition, the user can control the motor 5 to drive the rotating shaft 17 and the scraper 16 to rotate and scrape the impurities on the surface of the filter screen 21 so that the impurities fall on the buffer plate 7.

[0038] After circulating water flows onto the fixed plate 8, it is divided into multiple filter cylinders 9. The circulating water then flows downward along the filter cylinders 9 and is filtered by the filter element 10. The filtered water flows into the bottom of the tank 1 and is discharged through the drain pipe 2. When the filter element 10 needs to be replaced, the user can pull the cover plate 3 upward to remove it from the top of the tank 1. Then, the user can turn the screw 22 to disengage it from the screw hole 23 and pull the buffer plate 7 upward to remove it from the tank 1. At this time, the user can clean the large impurities on the buffer plate 7. Then, the user can turn the filter cylinder 9 to disengage the threaded groove on the filter cylinder 9 from the screw hole 13 and pull the filter cylinder 9 upward to remove it and replace the filter element 10.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
