Description

Technical Field

[0001] The present invention relates to the field of water environmental protection, and in particular to a multiple filtering device for water environmental protection discharge. Background Art

[0002] Filtration is an important part of water environmental protection. The focus of filtration is heavy metals, silt, sediments and suspended matter, which are all impurities that need to be filtered. Existing personnel often pay attention to sediments and impurities, but often ignore suspended particles. The more suspended particles are filtered, the more it affects the filtration effect of the upper end of the filter element and also causes blockage of the water inlet. Moreover, among the sediment particles, the ones at the bottom are often large-particle structures, and the silt and metal impurities need to be dredged to avoid affecting the filtration effect. However, most dredging functions require manual disassembly or the activation of another set of autonomous cleaning systems, which affects the conventional filtration function and reduces the overall filtration efficiency.

[0003] Therefore, those skilled in the art have designed a multi-filtration device for water environmental discharge to solve the above problems. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a multi-filtration device for water environmental discharge, which can be adapted for welding meshes with different spacings.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: it includes an upper filter frame and a lower filter frame connected to each other up and down, a filter element is installed on the inside of the upper filter frame, a hose is connected to the bottom of the filter element, and blockages are connected on both sides of the bottom of the filter element. A water outlet is penetrated through the bottom of the upper filter frame and is slidably connected to the blockage, supernatant discharge pipes connected to the top of the filter element are connected on both sides of the upper filter frame, a water inlet is connected to the top of the upper filter frame, and an energy storage component is installed at the bottom of the upper filter frame.

[0006] Preferably, the inner wall of the lower filter frame is connected with fine filter cotton, and the fine filter cotton is in a spiral downward water outlet channel structure, and the fine filter cotton is in sliding connection with the blockage.

[0007] Preferably, the surface of the filter element is provided with corrugated pleats, and the filter element can be longitudinally compressed. A crushing spring is connected to the inside of the filter element, and cutting blades are distributed on the surface of the crushing spring. A baffle is connected to the bottom of the filter element.

[0008] Preferably, the baffle is a conical structure, and a distance of 0.5 cm to 1 cm is maintained between the baffle and the bottom of the filter element, and the baffle is located directly above the hose.

[0009] Preferably, the energy storage assembly includes a limit tube, a limit opening, a clip and an energy storage spring. The limit tube and the filter element are fixedly connected to each other. The limit openings are opened on both sides of the limit tube. The inner side of the lower filter frame is connected to a clip that is mutually engaged with the limit opening through a torsion spring. The center of the limit tube is connected to an energy storage spring.

[0010] Preferably, when the limiting tube moves downward, the buckles are engaged with the limiting openings on the limiting tube in sequence, and when the limiting tube moves upward, the buckles form a sliding connection with the outer wall of the limiting tube.

[0011] Preferably, a one-way valve 1 is provided at the connection between the hose and the filter element, and the one-way valve 1 is connected to the bottom of the filter element, and a one-way valve 2 is provided in the supernatant discharge pipe. When the filter element is compressed, the one-way valve 1 and the one-way valve 2 are in a conducting state, and when the filter element is stretched, the one-way valve 1 and the one-way valve 2 are in a closed state.

[0012] Preferably, a drain port is passed through the blocking surface, and when the drain port is lower than the water outlet at the bottom of the upper filter frame, the upper filter frame and the lower filter frame are connected to each other.

[0013] The beneficial effects of the present invention are as follows: the downward pressure of sewage is stored by the energy storage component, and as the amount of sewage in the filter element increases, the energy stored in the energy storage component continues to increase. When the stored energy reaches a certain level, it is released through the rapid upward rebound of the bottom of the filter element, squeezing the upper liquid and lower sediment of the filter element outward, leaving most of the sewage in the middle part, avoiding clogging of the filter element. At the same time, the self-cleaning function is realized by the impact pressure, and the spiral fine filter cotton at the bottom can perform secondary filtration on water resources. At the same time, the filter element also adopts a pleated, easy-to-fold structure, which is easier to be compressed up and down. When pushed downward, it can not only accumulate energy but also absorb more sewage. When squeezed upward, it can discharge sediment and suspended matter outward, reducing impurities in the filter element. At the same time, the crushing spring used can also squeeze and crush the sediment, facilitating the discharge of large particles while reducing the risk of pipe or filter element blockage. Heavy metal pollutants and silt and other sewage are discharged separately and separated from the filtered water resources, greatly reducing the pollution of the filtered water resources. At the same time, the reusable characteristics of the energy storage mechanism can realize the function of autonomous and automatic dredging without the need for human intervention, thus realizing the reusability of resources.

[0026] Example 1: It includes an upper filter frame 1 and a lower filter frame 2 that are connected to each other from top to bottom. A filter element 3 is installed on the inside of the upper filter frame 1. A hose 5 is connected to the bottom of the filter element 3. Both sides of the bottom of the filter element 3 are connected to blockages 6. A water outlet is passed through the bottom of the upper filter frame 1 and is slidably connected to the blockage 6. Both sides of the upper filter frame 1 are connected to supernatant discharge pipes 7 that are connected to the top of the filter element 3. The top of the upper filter frame 1 is connected to a water inlet 4. The bottom of the upper filter frame 1 is installed with an energy storage component 8 The inner wall of the lower filter frame 2 is connected with fine filter cotton 201, and the fine filter cotton 201 is in a spiral downward water outlet channel structure. The fine filter cotton 201 is in sliding connection with the obstruction 6. The spiral fine filter cotton 201 can maintain the rolling of the water flow while maintaining the downstream speed of the fluid, and can also play a filtering role to avoid the slow movement of the fluid caused by water blockage; The surface of the filter element 3 is provided with corrugated pleats. The pleated structure of the filter element 3 can make it easier for the filter element 3 to be stacked and folded up and down, and the filter element 3 can be compressed longitudinally. The compressed filter element 3 controls the outflow or inward absorption of the fluid in the filter element 3. A breaking spring 301 is connected to the inside of the filter element 3, and cutting blades are distributed on the surface of the breaking spring 301. When the filter element 3 is compressed, the cutter on the breaking spring 301 can cut the suspended particles or sediment in the filter element 3 to facilitate its discharge outward. A baffle 302 is connected to the bottom of the filter element 3. The baffle 302 can cover the hose 5 to prevent water from directly rushing out. The baffle 302 is a conical structure, which keeps the sediment from accumulating on both sides, making it easier for the blade on the breaking spring 301 to cut. The baffle 302 is kept at a distance of 0.5 cm to 1 cm from the bottom of the filter element 3. This distance can prevent large sediment particles from entering and clogging the hose 5. The baffle 302 is located directly above the hose 5. The energy storage component 8 includes a limit tube 801, a limit port 802, a buckle 803 and an energy storage spring 804. The limit tube 801 is fixedly connected to the filter element 3. The limit ports 802 are provided on both sides of the limit tube 801. The inner side of the lower filter frame 2 is connected to a buckle 803 that is mutually engaged with the limit port 802 through a torsion spring. The center of the limit tube 801 is connected to an energy storage spring 804. The energy storage component 8 mainly accumulates the energy when the sewage is flushed downward. When the limit tube 801 and the bottom of the filter element 3 are forced to move downward, the energy storage component 8 ... When the filter element 3 is in motion, the energy storage spring 804 can be pressed synchronously, and the two sides are kept in the pressed state through the limit opening 802 and the buckle 803. As the pressing depth increases, when there is no limit opening 802 for the buckle 803 to be engaged, the elastic force of the energy storage spring 804 is released outward to reversely compress the filter element 3, emptying the bottom sediment and the upper suspension while crushing large particles. A soft leather cover can also be provided on the outside of the limit tube 801 to prevent sewage leakage when the limit tube 801 slides up and down; When the limiting tube 801 moves downward, the buckle 803 is sequentially engaged with the limiting opening 802 on the limiting tube 801. When the limiting tube 801 moves upward, the buckle 803 forms a sliding connection with the outer wall of the limiting tube 801. The direct engagement effect between the buckle 803 and the limiting opening 802 gradually increases the pressing force of the energy storage spring 804. At the same time, the downward pressure of the sediment also increases the pressure acting on the upper surface of the energy storage spring 804. A one-way valve 1 is provided at the connection between the hose 5 and the filter element 3, and the one-way valve 1 is connected to the bottom of the filter element 3. A one-way valve 2 is provided in the supernatant discharge pipe 7. When the filter element 3 is compressed, the one-way valve 1 and the one-way valve 2 are in a conducting state. When the filter element 3 is stretched, the one-way valve 1 and the one-way valve 2 are in a closed state. The one-way valve 1 and the one-way valve 2 will only open outward when the internal filter element 3 is squeezed outward, thereby discharging floating particles or bottom sediment. A drain port 601 is provided on the surface of the obstruction 6. When the height of the drain port 601 is lower than the water outlet at the bottom of the upper filter frame 1, the upper filter frame 1 and the lower filter frame 2 are connected to each other. The drain port 601 will be automatically opened only when the obstruction 6 drops to a certain height. The reason for not discharging immediately is that the water flow is gathered to form a certain impact pressure. Secondly, a soft and foldable rubber sleeve can be provided on the outer wall of the energy storage component 8 to prevent sewage from leaking downward.

[0027] Working principle: The water source that needs to be purified in the industry is input into the water inlet 4. After a large amount of sewage is flushed into the water inlet 4, it will push the bottom of the filter element 3 to move downward and realize the downward stretching of the filter element 3. Under the action of water pressure, the filter element 3 can filter the sewage. The filtered water resources enter the upper filter frame 1. The bottom of the filter element 3 drives the blocking 6 to move downward synchronously. When the drain port 601 passes through the water outlet at the bottom of the upper filter frame 1, the upper filter frame 1 and the lower filter frame 2 are connected from top to bottom, allowing the filtered water flow to enter the lower filter frame 2 for secondary filtration. The fine filter cotton 201 uses finer holes than the filter element 3 to filter the water resources more finely. When the bottom of the filter element 3 moves downward, it will drive the limiting tube 801 to move downward synchronously. When the limiting tube 801 passes the buckle 803, the buckle 803 will engage with the limiting opening 802 in turn, preventing the filter element 3 from rebounding upward while maintaining continuous pressure on the energy storage spring 804. When the limiting tube 801 continues to move downward and there is no limiting opening 802 for the buckle 803 to engage, the limiting tube 801 will slide upward rapidly under the action of the energy storage spring 804, causing the filter element 3 to be compressed. When the filter element 3 is compressed, the internal liquid tends to leak outward actively. The one-way valve 1 and the one-way valve 2 are connected, and the supernatant discharge pipe 7 sprays the suspended liquid above outward, while the hose 5 sprays the sediment outward. In addition, during the compression process, the energy storage spring 804 can crush the suspended particles or sediment through the blade on the surface, playing a role in rapid discharge. When the filter element 3 moves downward again under the action of inertia, the limiting tube 801 will be limited here by the buckle 803, which not only discharges the sediment and suspension but also avoids the leakage of sewage, and always keeps the filter element 3 in a high-efficiency filtration state.
