Description

Technical Field

[0001] The invention belongs to the field of sewage purification, in particular to a sewage purification device. Background Art

[0002] Wastewater purification is a complex process that aims to remove pollutants from sewage to make it meet discharge standards or be reusable. Flocculants are often used in traditional sewage purification. Flocculants are used as a means to enhance solid-liquid separation in the field of sewage treatment. They can be used to enhance the primary sedimentation, flotation treatment and secondary sedimentation after the activated sludge method of sewage. They can also be used for tertiary treatment or deep treatment of sewage. When flocculants are added to the sewage and fully mixed, the impurities in the sewage will stick together and clump. Subsequently, the clumped impurities are separated from the purified water through the filtering structure before the next step of purification.

[0003] A patent document with publication number CN214437029U discloses an environmentally friendly sewage filtering and purification treatment device, including a purification box, a water pump, a water pipe and a diversion pipe. A nozzle is fixedly arranged at the bottom of the diversion pipe. The interior of the purification box is provided with a first filter plate and a second filter plate from top to bottom. An impurity box is fixedly arranged on one side of the purification box, and cleaning boxes are fixedly arranged on both sides of the inner wall of the purification box. A motor is fixedly arranged inside the cleaning box, and the output shaft of the motor is fixedly connected to a rotating shaft.

[0004] In the conventional technology, flocculants are added into the sewage to make the impurities in the sewage stick together and then separated and filtered. In the conventional technology, a plurality of fixed inclined plates are provided to separate and filter the agglomerated impurities. The spacing between the plurality of inclined plates is smaller than the diameter of the agglomerated impurities, thereby blocking the agglomerated impurities and allowing the purified water to pass through. However, the purification efficiency is not easy to adjust under this method, which affects the purification efficiency when treating sewage with large agglomerated impurities.

[0008] Preferably, the water guide bar comprises a fixed bar fixedly mounted on the top of the clean water tank, a plurality of triangular blocks are fixedly mounted above the fixed bar, and arc-shaped sheets are fixedly mounted on the tops of the plurality of triangular blocks.

[0009] Preferably, the oblique partition includes a long strip and short strips movably installed on both sides of the long strip, and a plurality of telescopic components are installed at the intervals between the short strip and the long strip.

[0010] Preferably, the regulating member comprises a fixed inclined plate fixedly connected to the inside of the clean water tank, a sliding groove is provided on both sides of the fixed inclined plate, a plurality of electrically driven telescopic rods are fixedly installed inside the sliding groove, and a sliding block is slidably installed inside the sliding groove. One end of the plurality of electrically driven telescopic rods is connected to the sliding block, and an regulating plate is fixedly installed on one side of the sliding block. The regulating plate is connected to the corresponding oblique partition through a plurality of telescopic components.

[0011] Preferably, the telescopic assembly includes an elastic water-blocking ring and a telescopic member installed inside the elastic water-blocking ring, one end of the elastic water-blocking ring and the telescopic member is connected to the side of the long strip, and the other end of the elastic water-blocking ring and the telescopic member is connected to the side of the short strip.

[0012] Preferably, the telescopic member includes a fixed rod and a sliding rod slidably installed inside the fixed rod, and the elastic waterproof ring surrounds the outer side of the telescopic member, and the elastic waterproof ring elastically deforms as the sliding rod slides.

[0013] Preferably, a guide groove is provided inside the fixed rod, and a guide is fixedly installed on the outer side of the sliding rod, and the sliding rod slides inside the guide groove.

[0014] Preferably, a plurality of positioning structures are installed on the outer side of the sliding rod, and a plurality of positioning grooves and gradient grooves are provided inside the fixing rod. The positioning grooves and gradient grooves are connected, and the positioning structures slide inside the positioning grooves.

[0015] Preferably, the width of the gradient groove is smaller than the width of the positioning groove, the width of the gradient groove at one end away from the sliding rod is smaller than the width of the gradient groove at one end close to the sliding rod, and the connection between the gradient groove and the positioning groove is smoothly arranged.

[0016] Preferably, the positioning structure comprises a fixed round block and a plurality of arc-shaped blocks movably mounted outside the fixed round block, and a plurality of spring guide pillars are movably mounted between the plurality of arc-shaped blocks and the fixed round block.

[0017] The beneficial effects of the present invention are as follows: 1. A sewage purification device described in the present invention accumulates filtered water at the top of a clean water tank until the water level is higher than the bottom of the water tank, and the purified water flows into the water baffle, and is then transported away through an outlet pipe for further purification. In the device, a plurality of inclined baffles are connected by a telescopic assembly, and the telescopic assembly can drive the movement of the plurality of inclined baffles, thereby adjusting the spacing between the lower end plates of the plurality of inclined baffles. For sewage with a large diameter of clumped impurities, the spacing between the lower end plates of the plurality of inclined baffles can be increased. At this time, more purified water can pass through the inclined baffles, thereby improving the sewage purification efficiency.

[0018] 2. The sewage purification device described in the present invention is electrically driven to extend the telescopic rod, so that the adjustment plate and the sliding block are away from the fixed inclined plate. The sliding block is always in the sliding groove during the movement, so that the agglomerated impurities will not rise through the adjustment component. After the adjustment plate moves, it will squeeze the multiple inclined partitions. The original thickness of the multiple inclined partitions is compressed, causing the telescopic component to shrink. At this time, the distance between the lower ends of the long strips and the short strips is reduced, which can block the passage of small-diameter agglomerated impurities. At this time, the elastic water-blocking ring is a component made of waterproof rubber material, which can protect the telescopic component from corrosion. By contracting the electrically driven telescopic rod, the adjustment plate is moved toward the fixed inclined plate, which can stretch the telescopic component, increase the distance between the lower ends of the long strips and the short strips, block the large-diameter agglomerated impurities that only exist in the sewage, and increase the sewage purification efficiency.

[0019] 3. The sewage purification device described in the present invention, when the telescopic parts arranged in the multiple oblique partitions are contracted, the positioning structure initially slides inside the positioning groove, thereby ensuring that the distance between the lower ends of the multiple long boards and the short boards remains basically consistent. When the telescopic parts need to continue to contract, that is, when the distance between the lower ends of the multiple long boards and the short boards continues to be reduced, the positioning structure slides into the inside of the gradient groove. The groove inside the gradient groove is gradually reduced. Therefore, even if the distance between the lower ends of the multiple long boards and the short boards continues to be reduced, the multiple distances will be kept basically consistent. The spacing requirement for the plates for blocking clumped impurities is relatively small. Therefore, the use of an electrical telescopic structure to adjust the blocking spacing consumes a lot of resources. The device ensures that the distance between the lower ends of the multiple long boards and the short boards after adjustment remains basically consistent through the setting between the structures without the need for a large number of telescopic electrical rods.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] Embodiment 1 like Figure 1-Figure 5 As shown, a sewage purification device according to an embodiment of the present invention comprises a clean water tank 2 and a water outlet pipe 1 installed at one side of the clean water tank 2, a filter chamber 25 is provided at the inner bottom of the clean water tank 2, a rotary filter device 23 is movably installed inside the filter chamber 25, a sludge pump 3 is fixedly installed at the outer bottom of the clean water tank 2, a water inlet 21 is provided through the inner top side of the clean water tank 2, a guide plate 22 and a water baffle 24 are fixedly installed inside the clean water tank 2, a water guide bar 4 and a blocking mechanism 5 are installed between the guide plate 22 and the water baffle 24, a water trough 241 is provided at the top of the water baffle 24, the water guide bar 4 and the blocking mechanism 5 are both connected to the inner wall of the clean water tank 2, and the horizontal height of the water guide bar 4 is lower than the horizontal height of the guide plate 22 and the water baffle 24; The blocking mechanism 5 includes a plurality of adjusting components 7 fixedly mounted on the inner wall of the clean water tank 2, a plurality of inclined partitions 6 are mounted on the sides of the plurality of adjusting components 7, a plurality of telescopic components 8 are mounted between the plurality of inclined partitions 6, and the plurality of inclined partitions 6 are connected to each other through the plurality of telescopic components 8.

[0025] Specifically, after the sewage is mixed with the flocculant, the impurities in the sewage will clump. At this time, the sewage containing the clumped impurities enters the clean water tank 2 through the water inlet 21. At this time, the sewage will first be guided by the guide plate 22 to generate a downward water flow, so that the impurities in the sewage fall inside the filter chamber 25 under the dual factors of diversion and gravity. At the same time, the rotary filter device 23 is electrically driven to rotate, further attracting the clumped impurities in the sewage to fall. When there are a lot of impurities accumulated, a large amount of impurities can be pumped away by the sludge pump 3. When the sewage transported from the outside enters the clean water tank 2 again, it will collide with the original water in the clean water tank 2. Therefore, some of the clumped impurities will rise inside the clean water tank 2. At this time, a blocking mechanism 5 is set at the inner top of the clean water tank 2. The blocking mechanism 5 is composed of a plurality of oblique partitions 6. The spacing between the lower end plates of the oblique partitions 6 is smaller than the diameter of the clumped impurities, that is, the impurities that rise due to the impact of the water flow are blocked. The clumped impurities are blocked. At this time, the filtered water will accumulate at the top of the clean water tank 2 until the water level is higher than the bottom of the water tank 241. The purified water will enter the inside of the baffle 24 and then be transported away through the outlet pipe 1 for further purification. In this device, multiple oblique baffles 6 are connected by a telescopic component 8. The telescopic component 8 can drive the multiple oblique baffles 6 to move, thereby adjusting the spacing between the lower end plates of the multiple oblique baffles 6. When dealing with sewage with a large diameter of clumped impurities, the spacing between the lower end plates of the multiple oblique baffles 6 can be increased. At this time, more purified water can be passed through the oblique baffles 6, thereby improving the purification efficiency of sewage. When dealing with sewage with a small diameter of clumped impurities, the spacing between the lower end plates of the multiple oblique baffles 6 can be reduced, and the sewage purification effect will not be poor. According to actual needs, the spacing between the lower end plates of the multiple oblique baffles 6 is adjusted to maximize the sewage purification efficiency.

[0026] like Figure 3 As shown, the water guide bar 4 includes a fixed bar 41 fixedly installed on the top of the clean water tank 2, a plurality of triangular blocks 42 are fixedly installed above the fixed bar 41, and an arc-shaped piece 43 is fixedly installed on the top of the plurality of triangular blocks 42.

[0027] Specifically, the purified water after impurities are removed inside the clean water tank 2 will accumulate. When the water level is higher than the height of the fixed bar 41, due to the arrangement of multiple arc-shaped pieces 43, the purified water above the water level of the fixed bar 41 needs to flow from the gaps between the multiple triangular blocks 42. By suddenly reducing the water flow path, the water flow rate is increased, thereby improving the purification efficiency. The arc-shaped piece 43 arranged on the top of the triangular block 42 is used to prevent the water flow from directly impacting the water guide bar 4 and causing damage.

[0028] like Figure 5-Figure 8As shown, the oblique partition 6 includes a long strip 61 and short strips 62 movably mounted on both sides of the long strip 61, and a plurality of telescopic components 8 are installed at the interval between the short strip 62 and the long strip 61. The adjustment member 7 includes a fixed oblique plate 71 fixedly connected to the inside of the clean water tank 2, and a sliding groove 72 is provided on both sides of the fixed oblique plate 71. A plurality of electrically driven telescopic rods 73 are fixedly installed inside the sliding groove 72, and a sliding block 75 is slidably installed inside the sliding groove 72. One end of the plurality of electrically driven telescopic rods 73 is connected to the sliding block 75, and an adjustment plate 74 is fixedly installed on one side of the sliding block 75. The adjustment plate 74 is connected to the corresponding oblique partition 6 through a plurality of telescopic components 8.

[0029] The telescopic assembly 8 includes an elastic water-blocking ring 81 and a telescopic member 82 installed inside the elastic water-blocking ring 81. One end of the elastic water-blocking ring 81 and the telescopic member 82 is connected to the side of the long strip 61, and the other end of the elastic water-blocking ring 81 and the telescopic member 82 is connected to the side of the short strip 62. Specifically, the oblique partition 6 is composed of a long strip 61 and a short strip 62. The height of the short strip 62 is smaller than that of the long strip 61. After the purified water passes through the gap between the lower ends of the long strip 61 and the short strip 62, it rises to the upper end of the long strip 61. At this time, the gap between the two adjacent long strips 61 is larger, and more water can pass through. Compared with the traditional setting of multiple identical plates, the upper end of the oblique partition 6 in the device can pass more purified water. When it is necessary to adjust the gap between the lower ends of the long strip 61 and the short strip 62, the electrically driven telescopic rod 73 is electrically driven to extend, so that the adjustment plate 74 and the sliding block 75 are away from the fixed oblique plate 71, and the sliding block 75 is always in the sliding groove 72 during the movement. Inside, the clumped impurities will not rise through the adjusting component 7. After the adjusting plate 74 moves, it will squeeze the multiple oblique partitions 6. The original thickness of the multiple oblique partitions 6 is compressed, causing the telescopic member 82 to shrink. At this time, the distance between the lower ends of the long strips 61 and the short strips 62 is reduced, which can block the passage of small-diameter clumped impurities. At this time, the elastic water-blocking ring 81 is a component made of waterproof rubber material, which can protect the telescopic member 82 from corrosion. The telescopic rod 73 is electrically driven to shrink, so that the adjusting plate 74 moves toward the fixed oblique plate 71, which can stretch the telescopic member 82, increase the distance between the lower ends of the long strips 61 and the short strips 62, and block the large-diameter clumped impurities that only exist in the sewage, thereby increasing the sewage purification efficiency.

[0030] like Figure 8 As shown, the telescopic member 82 includes a fixed rod 821 and a sliding rod 822 slidably mounted inside the fixed rod 821. The elastic water-blocking ring 81 surrounds the outer side of the telescopic member 82. The elastic water-blocking ring 81 elastically deforms as the sliding rod 822 slides. A guide groove 8211 is provided inside the fixed rod 821, and a 8221 is fixedly mounted on the outer side of the sliding rod 822, and 8221 slides inside the guide groove 8211.

[0031] A plurality of positioning structures 83 are installed on the outer side of the sliding rod 822 , and a plurality of positioning grooves 8212 and gradient grooves 8213 are provided inside the fixed rod 821 . The positioning grooves 8212 and gradient grooves 8213 are connected, and the positioning structures 83 slide inside the positioning grooves 8212 .

[0032] The width of the gradient groove 8213 is smaller than that of the positioning groove 8212 , the width of the gradient groove 8213 away from the sliding rod 822 is smaller than the width of the gradient groove 8213 close to the sliding rod 822 , and the connection between the gradient groove 8213 and the positioning groove 8212 is smoothly arranged.

[0033] Specifically, the sliding rod 822 slides inside the fixed rod 821 through the matching of 8221 and the guide groove 8211, and the positioning structure 83 initially slides inside the positioning groove 8212. When the electrically driven telescopic rod 73 is extended, the telescopic member 82 is driven to retract. At this time, the sliding rod 822 slides toward the inside of the fixed rod 821, that is, the positioning structure 83 slides inside the positioning groove 8212 toward the inside of the gradient groove 8213. The positioning structure 83 is set as a sliding plate that can shrink. Because the diameter of the gradient groove 8213 is smaller than the positioning groove 8212, when the telescopic members 82 arranged in the multiple oblique partitions 6 are retracted, the positioning structure 83 initially slides inside the positioning groove 8212, thereby ensuring that the multiple long strips 61 and The spacing between the lower ends of the short strips 62 remains basically the same. When the telescopic member 82 needs to continue to shrink, that is, to continue to reduce the spacing between the lower ends of the multiple long strips 61 and the short strips 62, the positioning structure 83 slides into the gradient groove 8213. The internal groove of the gradient groove 8213 is a gradually decreasing setting. Therefore, even if the spacing between the lower ends of the multiple long strips 61 and the short strips 62 continues to be reduced, the multiple spacings will be kept basically consistent. The spacing requirement for blocking the clumped impurities is relatively small. Therefore, the use of an electrical telescopic structure to adjust the blocking spacing consumes a lot of resources. The device ensures that the spacing between the lower ends of the multiple long strips 61 and the short strips 62 after adjustment remains basically consistent through the setting between the structures without the need for a large number of telescopic electrical rods.

[0034] Embodiment 2 like Fig. 9 As shown, compared with Example 1, another embodiment of the present invention is: the positioning structure 83 includes a fixed round block 831 and a plurality of arc blocks 832 movably installed on the outside of the fixed round block 831, and a plurality of spring guide columns 833 are movably installed between the plurality of arc blocks 832 and the fixed round block 831.

[0035] Specifically, when the positioning structure 83 enters the gradient groove 8213 from the positioning groove 8212, the arc block 832 moves toward the fixed round block 831, so that the spring guide column 833 is compressed, that is, the movement resistance of the positioning structure 83 in the positioning groove 8212 is different from that in the gradient groove 8213, so that when the adjustment plate 74 pushes the multiple long strips 61 and the short strips 62 to move in compression, the distance between the lower ends of the multiple long strips 61 and the short strips 62 is basically the same. When sliding deep in the strip groove 8213, the required thrust is greater, further ensuring that the spacing between the lower ends of the multiple long strips 61 and the short strips 62 remains basically consistent. When the sliding rod 822 slides toward the outside of the fixed rod 821, the positioning structure 83 slides outward from the depth of the gradient strip groove 8213. At this time, under the spring restoring force of the spring guide column 833, the positioning structures 83 on the outside of each long strip 61 will slide outward from the depth of the gradient strip groove 8213 at the same time, basically keeping the spacing between the lower ends of the multiple long strips 61 and the short strips 62 consistent.

[0036] Working principle: After the sewage is mixed with the flocculant, the impurities in the sewage will clump. At this time, the sewage containing the clumped impurities enters the clean water tank 2 through the water inlet 21. At this time, the sewage will first be guided by the guide plate 22 to generate a downward water flow, so that the impurities in the sewage will fall inside the filter chamber 25 under the dual factors of diversion and gravity. At the same time, the rotary filter device 23 is electrically driven to rotate, further attracting the clumped impurities in the sewage to fall. When there are a lot of impurities accumulated, a large amount of impurities can be pumped away by the sludge pump 3. When the sewage transported from the outside enters the clean water tank 2 again, it will collide with the original water in the clean water tank 2. Therefore, some of the clumped impurities will rise inside the clean water tank 2. At this time, a blocking mechanism 5 is set at the inner top of the clean water tank 2. The blocking mechanism 5 is composed of a plurality of oblique partitions 6. The spacing between the lower end plates of the oblique partitions 6 is smaller than the diameter of the clumped impurities, that is, the impurities that rise due to the impact of the water flow are blocked. The clumped impurities are blocked. At this time, the filtered water will accumulate at the top of the clean water tank 2 until the water level is higher than the bottom of the water tank 241. The purified water will enter the inside of the baffle 24 and then be transported away through the outlet pipe 1 for further purification. In this device, multiple oblique baffles 6 are connected by a telescopic component 8. The telescopic component 8 can drive the multiple oblique baffles 6 to move, thereby adjusting the spacing between the lower end plates of the multiple oblique baffles 6. When dealing with sewage with a large diameter of clumped impurities, the spacing between the lower end plates of the multiple oblique baffles 6 can be increased. At this time, more purified water can be passed through the oblique baffles 6, thereby improving the purification efficiency of sewage. When dealing with sewage with a small diameter of clumped impurities, the spacing between the lower end plates of the multiple oblique baffles 6 can be reduced, and the sewage purification effect will not be poor. According to actual needs, the spacing between the lower end plates of the multiple oblique baffles 6 is adjusted to maximize the sewage purification efficiency.

[0037] The oblique partition 6 is composed of a long strip 61 and a short strip 62. The height of the short strip 62 is smaller than that of the long strip 61. After the purified water passes through the gap between the lower ends of the long strip 61 and the short strip 62, it rises to the upper end of the long strip 61. At this time, the gap between the two adjacent long strips 61 is larger, and more water can pass through. Compared with the traditional setting of multiple identical plates, the upper end of the oblique partition 6 in the present device can pass more purified water. When it is necessary to adjust the gap between the lower ends of the long strip 61 and the short strip 62, the electric drive telescopic rod 73 is electrically driven to extend, so that the adjustment plate 74 and the sliding block 75 are away from the fixed oblique plate 71, and the sliding block 75 is always in the sliding groove 72 during the movement. , so that the clumped impurities will not rise through the adjusting component 7. After the adjusting plate 74 moves, it will squeeze the multiple oblique partitions 6. The original thickness of the multiple oblique partitions 6 is compressed, causing the telescopic member 82 to shrink. At this time, the distance between the lower ends of the long strips 61 and the short strips 62 is reduced, which can block the passage of small-diameter clumped impurities. At this time, the elastic water-blocking ring 81 is a component made of waterproof rubber material, which can protect the telescopic member 82 from corrosion. The telescopic rod 73 is electrically driven to shrink, so that the adjusting plate 74 moves toward the fixed oblique plate 71, and the telescopic member 82 can be stretched, thereby increasing the distance between the lower ends of the long strips 61 and the short strips 62, thereby blocking the large-diameter clumped impurities that only exist in the sewage, thereby increasing the sewage purification efficiency.
