Description

Technical Field

[0001] This utility model relates to the field of water purification equipment, and in particular to a high-efficiency filtration device for an integrated water purification system. Background Technology

[0002] In today's society, the rational use and purification of water resources has become a key global issue.

[0003] Integrated water purification equipment uses one or more filter media to remove impurities from the raw liquid under certain pressure, thereby achieving the purpose of filtration. The fillers inside are generally: quartz sand, anthracite, granular porous ceramics, manganese sand, etc.

[0004] When using integrated water purification equipment, a high-efficiency filtration device is required for preliminary filtration. During this preliminary filtration, a filter screen is typically used to intercept impurities. Wastewater contains numerous impurities that easily accumulate on the filter screen, causing blockage. A blocked filter screen not only experiences a significant decrease in filtration efficiency but also requires frequent cleaning or replacement. Furthermore, under unstable water flow conditions, especially when the flow is weak, some areas of the filter screen cannot fully perform their filtration function, leading to excessive filtration burden in certain areas, accelerating localized blockage, and further reducing filtration efficiency. Therefore, a high-efficiency filtration device for integrated water purification equipment is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency filtration device for an integrated water purification system, aiming to improve the problem in the prior art that "the initial filtration of sewage often uses a filter screen to intercept impurities, but sewage with many impurities is prone to clogging the screen, resulting in a decrease in filtration efficiency. Moreover, when the water flow is low, the filter screen is overburdened in some areas, which accelerates local clogging and reduces filtration efficiency."

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency filtration device for an integrated water purification system, comprising a water storage tank, a connecting pipe fixedly connected to the lower part of the water storage tank, an outer shell disposed on the right side of the connecting pipe, a filter screen disposed on the inner wall of the outer shell, a protective cover disposed on the upper part of the outer shell, a filtration mechanism disposed on the inner wall of the outer shell, the filtration mechanism comprising a filter assembly and a sealing assembly, the filter assembly comprising a drive motor, the drive motor fixedly connected to the outer side of the outer shell, a rotating rod fixedly connected to the output shaft of the drive motor, the rotating rod rotatably connected to the inner wall of the outer shell, a baffle fixedly connected to the outer side of the rotating rod, a sleeve slidably connected to the outer side of the baffle, the sleeve and the baffle being elastically connected by a compression spring, a contact element fixedly connected to the left side of the sleeve, a connecting element fixedly connected to the inner wall of the filter screen, and a fixing element fixedly connected to the right side of the connecting element.

[0007] As a further description of the above technical solution:

[0008] The sealing assembly includes a fixing sleeve, which is fixedly connected to the outside of the filter screen and rotatably connected to the inner wall of the outer shell. The upper part of the fixing sleeve rotates on the lower inner wall of the protective cover. A sealing ring is fixedly connected to the outside of the fixing sleeve, and the outer side of the sealing ring contacts the outer shell and the inner wall of the protective cover.

[0009] As a further description of the above technical solution:

[0010] One side of the fastener is set as an inclined surface, and the other side of the fastener is set as a vertical surface.

[0011] As a further description of the above technical solution:

[0012] The contact element slides on the outside of the fixing element.

[0013] As a further description of the above technical solution:

[0014] The cross-sections of all contact components are set as vertical surfaces.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the protective cover is provided with a fixing component, which includes a bolt. The bolt passes through the inner wall of the protective cover and is threaded to the inner wall of the outer shell. A slot is provided on the outer side of the bolt. A limit plate is slidably connected to the inner wall of the protective cover. The limit plate is inserted into the inner wall of the slot.

[0020] The limiting plate (83) is configured in an L shape.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the drive motor drives the rotating rod to rotate, causing the contact element to slide on the outside of the fixed part. When the contact element slides along the inclined surface of the fixed part, it squeezes and compresses the spring, and after leaving the vertical surface, it hits the connecting part, causing the filter screen to vibrate, shake off impurities, prevent clogging, and maintain a good filtration effect. At the same time, the rotating rod can rotate in the opposite direction to make the contact element drive the filter screen to rotate slowly. When the water flow is small, the unused area can participate in filtration, reduce local clogging, and improve filtration efficiency.

[0023] 2. In this utility model, through the combined use of the fixing component and the protective cover, the limiting plate is inserted into the inner wall of the slot on the bolt under the elastic force of the return spring, thereby preventing the bolt from loosening and enhancing the reliability of the connection.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a high-efficiency filtration device for an integrated water purification system, comprising a water storage tank 1 for storing water to be filtered. A connecting pipe 2 is fixedly connected to the lower part of the water storage tank 1, connecting the water storage tank 1 and the outer shell 3, so that the water in the water storage tank 1 can flow smoothly into the outer shell 3 for filtration. The outer shell 3 is provided on the right side of the connecting pipe 2, providing installation space and protection for the internal filter screen 5 and filtration mechanism. The inner wall of the outer shell 3 is provided with a filter screen 5, which filters the water flowing from the water storage tank 1 into the outer shell 3 through the connecting pipe 2 through its own filtration structure, initially removing impurities from the water. The upper part of the outer shell 3 is provided with a protective cover 4, and the lower part is provided with a sealing gasket to seal the outer shell 3 and provide protection. The inner wall of the outer shell 3 is provided with a filtration mechanism, which includes a filter component and a sealing component. The filter component includes a drive motor 61, which is the power source of the filter component. After starting, its output shaft rotates, providing rotational power to the rotating rod 62.

[0033] Reference Figure 2 - Figure 4 The drive motor 61 is fixedly connected to the outside of the housing 3. The output shaft of the drive motor 61 is fixedly connected to the rotating rod 62, which transmits the rotational motion of the drive motor 61 to the baffle 63, the sleeve 64 and the contact 66, so that it can rotate around the axis of the rotating rod 62. The rotating rod 62 is rotatably connected to the inner wall of the housing 3. The connection between the rotating rod 62 and the housing 3 is sealed. The baffle 63 is fixedly connected to the outside of the rotating rod 62 to fix the compression spring 65 and the sleeve 64. The sleeve 64 is slidably connected to the outside of the baffle 63. The outside of the baffle 63 is provided with a groove, and the sleeve 64 can slide inside the groove to restrict the rotation of the sleeve 64.

[0034] Reference Figure 2 - Figure 4The sleeve 64 and the baffle 63 are elastically connected by a compression spring 65. Pressure is applied to the sleeve 64 and the contact 66. When the rotating rod 62 rotates and causes the contact 66 to slide on the inclined surface of the fixing member 68, it can compress the compression spring 65. When the contact 66 disengages from the vertical surface of the fixing member 68, it can impact the connecting member 67, causing the filter screen 5 to vibrate and remove impurities from the filter screen 5, preventing clogging. The rotating rod 62 rotates in the opposite direction, allowing the vertical surface of the contact 66 to align with the vertical surface of the fixing member 68, causing the filter screen 5 to rotate slowly. When the water flow is small and cannot completely cover the filter screen 5, water can only pass through the lower area of ​​the filter screen 5. During filtration, the rotation of the filter screen 5 allows for filtration of areas that have not been used for a long time, reducing the occurrence of filter screen 5 clogging. A contact element 66 is fixedly connected to the left side of the sleeve 64. The cross-section of the contact element 66 is set as a vertical surface, which is used to press the fixing element 68. A connector 67 is fixedly connected to the inner wall of the filter screen 5, which serves to connect the filter screen 5 and the fixing element 68. A fixing element 68 is fixedly connected to the right side of the connector 67. The contact element 66 slides on the outside of the fixing element 68. One side of the fixing element 68 is set as an inclined surface, and the other side of the fixing element 68 is set as a vertical surface. In cooperation with the contact element 66, it can drive the filter screen 5 to rotate or vibrate, thereby reducing the occurrence of filter screen 5 clogging.

[0035] Reference Figure 2 and Figure 3 The sealing assembly includes a fixing sleeve 71 for fixing the filter screen 5 to the housing 3 and the protective cover 4. The fixing sleeve 71 is fixedly connected to the outside of the filter screen 5 and rotatably connected to the inner wall of the housing 3. The upper part of the fixing sleeve 71 rotates on the lower inner wall of the protective cover 4. A sealing ring 72 is fixedly connected to the outside of the fixing sleeve 71. The outer side of the sealing ring 72 contacts the inner walls of the housing 3 and the protective cover 4. Its main function is to enhance the sealing between the fixing sleeve 71 and the housing 3 and the protective cover 4 to prevent water leakage. At the same time, it increases the resistance when the filter screen 5 rotates, so that the contact 66 can slide on the inclined surface on one side of the fixing 68 to compress the compression spring 65.

[0036] Reference Figure 2 and Figure 5The inner wall of the protective cover 4 is provided with a fixing component, which includes a bolt 81. The bolt 81 penetrates the inner wall of the protective cover 4 and is threaded to the inner wall of the outer shell 3 to fix the protective cover 4 to the outer shell 3, ensuring a stable connection between the protective cover 4 and the outer shell 3. A slot 82 is provided on the outer side of the bolt 81. A limiting plate 83 is slidably connected to the inner wall of the protective cover 4. The limiting plate 83 is inserted into the inner wall of the slot 82. By inserting the limiting plate 83 into the inner wall of the slot 82, the bolt 81 is further limited to prevent it from vibrating during equipment operation. To prevent loosening due to various reasons, the reliability of the connection between the protective cover 4 and the outer shell 3 is enhanced. The limiting plate 83 is set in an L shape to facilitate the operator to press it, thereby releasing the limitation on the bolt 81. There are two sets of limiting plates 83. The opposite side of the two sets of limiting plates 83 is elastically connected to a return spring 84. The initial state is a compressed state, which provides elastic force so that the two sets of limiting plates 83 always tend to be inserted into the slot 82, ensuring a tight fit between the limiting plate 83 and the slot 82, enhancing the stability and reliability of the fixing component, and preventing the bolt 81 from loosening.

[0037] Working principle: When in use, start the drive motor 61, and its output shaft rotates to drive the rotating rod 62 to rotate. When the rotating rod 62 rotates, it drives the baffle 63 and sleeve 64 fixed on its outer side to rotate together. The contact 66 fixed on the left side of the sleeve 64 will slide on the outside of the fixed part 68 along with the sleeve 64. When the contact 66 slides to the inclined surface of the fixed part 68, the rotation of the rotating rod 62 causes the contact 66 to squeeze and compress the spring 65. The spring is compressed and generates elastic potential energy.

[0038] When the contact 66 disengages from the vertical surface of the fixing member 68, the compression spring 65 releases its elastic potential energy, pushing the sleeve 64 and the contact 66, causing the contact 66 to strike the connecting member 67, which in turn causes the filter screen 5 to vibrate. This vibration can shake off the impurities attached to the filter screen 5, effectively preventing the filter screen 5 from clogging and maintaining a good filtration effect.

[0039] When the rotating rod 62 rotates in the opposite direction, the vertical surface of the contact member 66 is in contact with the vertical surface of the fixing member 68, causing the filter screen 5 to rotate slowly. If the water flow is small and can only cover the lower area of ​​the filter screen 5 for filtration, the rotation of the filter screen 5 can allow areas that have not been used for a long time to participate in filtration, reducing the occurrence of local blockage and improving filtration efficiency.

[0040] The fixing sleeve 71 in the sealing assembly is fixedly connected to the outside of the filter screen 5 and rotatably connected to the inner wall of the outer shell 3 and the lower inner wall of the protective cover 4, providing stable rotational support for the filter screen 5. The sealing ring 72 on the outside of the fixing sleeve 71 seals while increasing the resistance when the filter screen 5 rotates, so that the contact 66 can slide stably on the inclined surface of the fixing 68, smoothly compressing the compression spring 65 and ensuring the normal operation of the filter assembly.

[0041] The protective cover 4 is threadedly connected to the inner wall of the outer shell 3 by bolts 81, thus achieving a fixed connection between the two. The retaining plate 83 on the outer side of the bolt 81 cooperates to limit the bolt 81. Under the elastic force of the return spring 84, which is initially in a compressed state, the retaining plate 83 is always provided with an elastic force to insert into the retaining plate 82, ensuring that the retaining plate 83 is tightly inserted into the retaining plate 82. This prevents the bolt 81 from loosening due to vibration or other reasons during equipment operation, ensuring the reliability of the connection between the protective cover 4 and the outer shell 3, and maintaining the stability of the overall structure of the equipment.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
