Description

Technical Field

[0001] The invention relates to the technical field of water treatment equipment, in particular to an agricultural non-point source water pollution treatment device. Background Art

[0002] In the field of water environment management, agricultural non-point source water pollution, due to its wide range of sources and complex pollutants, poses a serious threat to aquatic ecosystems. Effective treatment equipment is key to improving water quality. Such equipment must remove suspended impurities, silt, and other pollutants from wastewater through physical filtration and sedimentation. At the same time, it must provide stable operation and easy maintenance to meet the actual needs of agricultural production environments. Its core lies in achieving efficient separation and centralized treatment of pollutants through rational structural design, providing technical support for the comprehensive management of agricultural non-point source water pollution.

[0003] Existing agricultural non-point source water pollution treatment devices have obvious shortcomings. In terms of filtration efficiency, the filter components of traditional devices are easily clogged due to the accumulation of impurities, and lack an automatic cleaning mechanism. They need to be frequently manually disassembled and cleaned, which not only increases maintenance costs but also affects the continuity of treatment. In terms of impurity treatment, traditional equipment has difficulty in achieving centralized collection of pollutants. The cleaning process is cumbersome and prone to secondary pollution. Energy consumption and automation levels are low. Some devices rely on external power for cleaning or stirring, which consumes a lot of energy. In addition, the filtration and sedimentation links lack coordinated linkage. The settled sediment is easily disturbed by the water flow, reducing the treatment effect. In addition, traditional devices have weak adaptability to sewage with different pollution levels, and it is difficult to balance filtration accuracy and treatment efficiency, which restricts the large-scale application of agricultural non-point source water pollution control.

[0009] According to one embodiment of the present invention, the upper surface of the guide plate is slidably connected with an extrusion block, the extrusion block is arranged between adjacent partitions, the bottom of the extrusion block is fixedly connected with a push plate, the middle lower surface of the push plate is fixedly connected with a telescopic plate, and the two ends of the telescopic plate are fixedly connected to the inner surfaces of both sides of the outer shell.

[0010] According to one embodiment of the present invention, an extrusion bag is fixedly connected to the middle bottom surface of the slider, and the extrusion bag is fixedly installed in the slide groove. An air guide tube is fixedly connected through the bottom surface of the mounting seat, and the top of the air guide tube is connected to the internal cavity of the extrusion bag. The bottom of the air guide tube is fixedly connected to the bottom outer surface of the telescopic plate.

[0011] According to one embodiment of the present invention, the secondary processing mechanism includes a folding plate, which is arranged to be nearly U-shaped and fixedly connected to the middle inner surface of the outer shell, wherein the folding plate is arranged below the collection box, and the inner surface of the folding plate is fixedly connected with a guide plate, which is arranged to be arc-shaped, and an isolation groove is penetrated through the middle upper surface of the guide plate, and a processing groove is penetrated through the bottom upper surface of the folding plate.

[0012] According to one embodiment of the present invention, a sealing plate is movably embedded in the processing tank, and the upper surface of the sealing plate is fixedly connected to a buffer plate through a connecting rod. The buffer plate is initially arranged above the isolation tank, and the upper surface of the buffer plate is set as an arc surface. The bottom surface of the folding plate is fixedly connected to the isolation plate, and the isolation plate is fixedly connected to the bottom inner surface of the outer shell. Liquid outlet grooves are opened through the outer surfaces of both sides of the outer shell, and the liquid outlet grooves are set on the bottom outer side of the isolation plate.

[0013] According to one embodiment of the present invention, sliding rods are symmetrically fixedly connected to the bottom surface of the sealing plate on both sides, the bottom of the sliding rod passes through and is slidably connected to the lower surface of the isolation plate, the bottom of the sliding rod is fixedly connected to a connecting rod, the middle of the connecting rod is fixedly connected to a driving rod, and the top of the driving rod passes through the mounting seat and is fixedly connected to the lower surfaces of both sides of the slider, so that contaminated water with impurities is uniformly introduced through the water inlet at the top of the water collecting cover, and after the sewage enters the water collecting cover, it will enter the interior of the outer shell through its bottom, that is, it will be washed on the slider, and will flow to the No. 1 filter plate through the guiding effect of the slider, and the sewage will be filtered through the No. 1 filter hole on the No. 1 filter plate. The filtration is carried out to block larger impurities, and the filtered sewage is discharged through the outlet at the bottom of the outer shell. At the same time, the speed of sewage entering through the water inlet is the same as the speed of sewage passing through the No. 1 filter hole between the two partitions. After the sewage flows to the No. 1 filter plate, it will be filled on the top of the No. 1 filter plate due to the obstruction of the partition. At this time, with the introduction of sewage, larger impurities will be blocked by the partition on the No. 1 filter plate. When the No. 1 filter hole between the two partitions is blocked, the flow rate decreases. At this time, the sewage begins to spread downward through the partition on the top of the No. 1 filter plate, thereby realizing step-by-step spreading from the top to the bottom of the No. 1 filter plate until the No. 1 filter hole between all the partitions is blocked. After the filter holes are blocked, the sewage begins to enter the collection box through the bottom of the No. 1 filter plate and is filtered by the No. 2 filter plate at the bottom of the collection box. When the No. 1 filter plate is blocked more and more, more sewage will enter the collection box until the speed of entering the collection box is greater than the speed of flowing out of the collection box, which makes the sewage level in the collection box gradually rise, and eventually the sewage level submerges the contacts in the collection box, so that the two contacts are connected through electrical signals, and the electric hydraulic rod starts to work for one cycle, that is, the electric hydraulic rod starts to squeeze downward, thereby squeezing the slider to move it toward the slide groove in the mounting seat. , the baffle is driven downward by the downward movement of the slider, and then the guide plate connected to the bottom of the baffle is driven downward, and finally the partition is driven downward by the downward movement of the guide plate, that is, the partition begins to shrink toward the bottom of the No. 1 filter plate, and finally the top of the partition forms the same plane with the upper surface of the No. 1 filter plate. At this time, with the continuous introduction of sewage, the upper surface of the No. 1 filter plate is flushed as a whole with sewage, thereby flushing larger impurities along the inclined surface of the No. 1 filter plate into the collection box, and dredging the No. 1 filter hole. When the flushing is completed, the electric hydraulic rod resets and drives the slider to move upward, and then drives the partition to move up and reset, and resets the No. 1 filter plate to the interval shape again.

[0014] (3) Beneficial effects The present invention provides an agricultural non-point source water pollution treatment device. It has the following beneficial effects: (1) This agricultural non-point source water pollution treatment device can automatically clean the No. 1 filter hole when it is blocked during sewage filtering, which greatly improves the service life of the equipment and reduces the number of maintenance times due to blockage. At the same time, the cleaning process uses the source power of the sewage for flushing, which greatly reduces the use of external power and saves the cost of sewage treatment. The impurities after being flushed are concentrated in the collection box. The staff can complete the cleaning of the impurities in the collection box through the cleaning trough, which greatly reduces the maintenance difficulty of the equipment. By cooperating with the No. 1 filter plate and the collection box, the impurities can be concentrated and gathered simultaneously when the sewage is treated, avoiding the problem that the conventional filter plate is very easy to be blocked and requires frequent manual cleaning.

[0015] (2) In the agricultural non-point source water pollution treatment device, when the slider moves downward, it squeezes the squeezing bag at its bottom, causing the internal air pressure of the squeezing bag to increase, and finally transmits the internal air pressure to the telescopic plate through the air guide pipe connected to it, causing the telescopic plate to begin to expand upward, that is, it begins to push the push plate on the top of the telescopic plate upward, thereby driving the squeezing block on the push plate to move upward, so that the cavity between the bottom of the No. 1 filter plate and the guide plate is squeezed, thereby providing an outward pressure for the No. 1 filter hole on the No. 1 filter plate, thereby pushing the blockage in the No. 1 filter hole outward, and further cleaning the upper surface of the No. 1 filter plate in combination with the flushing of sewage. , it is possible to dredge the No. 1 filter hole simultaneously while cleaning the impurities accumulated on the surface of the No. 1 filter plate, thereby greatly improving the cleaning effect. When the No. 1 filter hole is not blocked or has been cleaned, the sewage will enter the guide plate through the No. 1 filter hole, and flow out from the bottom of the guide plate through the oblique guidance of the guide plate, and finally flow into the cavity formed by the outer shell and the folded plate, and precipitate the silt in the sewage. After the silt is precipitated, the sewage finally spreads over the top of the folded plate and flows to the water outlet for discharge, thereby realizing automatic further silt treatment after the sewage is filtered out of larger impurities, thereby greatly improving the sewage treatment effect.

[0016] (III) In the agricultural non-point source water pollution treatment device, after the sewage flows into the internal cavity of the folding plate, it will directly flow on the guide plate of the folding plate. At this time, the settled sediment will flow into the bottom cavity of the folding plate through the isolation trough and will be blocked by the guide plate to prevent the sewage from entering the folding plate and directly acting on the settled sediment, causing the sediment to be repeatedly stirred and reducing the sedimentation effect. When the slider moves downward, the connecting rod will be driven downward by the driving rod, and then the sliding rods at both ends will be pulled downward, and finally the sealing plate connected to the top of the sliding rod will be pulled downward, that is, the treatment at the bottom of the folding plate will be completed. When the trough is opened, the flow effect of sewage is used to flush and clean the sediment at the bottom of the folded plate, and finally it is discharged through the liquid outlet trough on the side surface of the outer shell, so that the sediment deposited at the bottom of the folded plate can be cleaned simultaneously when the No. 1 filter plate is cleaned, which greatly improves the automation level of the equipment and extends the working time of the equipment. At the same time, when the sealing plate moves downward, it will simultaneously drive the buffer plate to move downward to close the isolation trough, so that the isolation trough is automatically closed when the treatment trough is opened, avoiding the problem of large-scale loss of sewage after filtering out large impurities through the folded plate.

[0027] A sealing plate 65 is movably embedded in the processing tank 64. The upper surface of the sealing plate 65 is fixedly connected to a buffer plate 66 through a connecting rod. The buffer plate 66 is initially arranged above the isolation tank 63. The upper surface of the buffer plate 66 is set to an arc surface. The bottom surface of the folding plate 61 is fixedly connected to an isolation plate 67. The isolation plate 67 is fixedly connected to the bottom inner surface of the outer shell 1.

The top of the driving rod 611 passes through the mounting seat 51 and is fixedly connected to the lower surfaces of both sides of the slider 59.

[0029] During operation, the contaminated water with impurities is introduced at a uniform speed through the water inlet 3 at the top of the water collecting cover 2. After the sewage enters the water collecting cover 2, it will enter the interior of the outer shell 1 through its bottom, that is, it will be washed on the slider 59. Through the guiding effect of the slider 59, it will flow to the No. 1 filter plate 52, and the sewage will be filtered through the No. 1 filter hole 53 on the No. 1 filter plate 52 to block larger impurities. The filtered sewage is discharged through the water outlet 4 at the bottom of the outer shell 1. At the same time, the speed at which the sewage enters through the water inlet 3 is the same as the speed at which it passes through the No. 1 filter hole 53 between the two partitions 514. After the sewage flows to the No. 1 filter plate 52, it will be filled with the top of the No. 1 filter plate 52 due to the obstruction of the partition 514. At this time, with the introduction of sewage, larger impurities The sewage will be blocked by the partition 514 on the No. 1 filter plate 52. When the No. 1 filter hole 53 between the two partitions 514 is blocked, the flow rate will decrease. At this time, the sewage begins to spread downward through the partition 514 on the top of the No. 1 filter plate 52, thereby spreading step by step from the top to the bottom of the No. 1 filter plate 52. Until the No. 1 filter holes 53 between all the partitions 514 are blocked, the sewage begins to enter the collection box 54 through the bottom of the No. 1 filter plate 52 and is filtered by the No. 2 filter plate 55 at the bottom of the collection box 54. When the No. 1 filter plate 52 is blocked more and more, more sewage will enter the collection box 54, until the speed of entering the collection box 54 is greater than the speed of flowing out of the collection box 54, that is, the sewage in the collection box 54 is full of sewage. The sewage level begins to rise gradually, and eventually the sewage level submerges the contact 511 in the collection box 54, so that the two contacts 511 are connected through an electrical signal, and start to drive the electric hydraulic rod 510 to work for one cycle, that is, the electric hydraulic rod 510 starts to squeeze downward, thereby starting to squeeze the slider 59 to move it toward the slide groove 58 in the mounting seat 51, and the downward movement of the slider 59 drives the baffle 512 to move downward, thereby driving the guide plate 513 connected to the bottom of the baffle 512 to move downward, and finally the downward movement of the guide plate 513 drives the partition 514 to move downward, that is, the partition 514 starts to shrink toward the bottom of the first filter plate 52, and finally the top of the partition 514 forms the same plane with the upper surface of the first filter plate 52. At this time, as the sewage continues to flow, the upper surface of the baffle 514 is flush with the upper surface of the first filter plate 52. After the sewage is introduced, the upper surface of the No. 1 filter plate 52 is flushed as a whole with sewage, so that larger impurities are flushed into the collection box 54 along the inclined surface of the No. 1 filter plate 52, and the No. 1 filter hole 53 is dredged. When the flushing is completed, the electric hydraulic rod 510 is reset to drive the slider 59 to move upward, and then drive the partition 514 to move upward and reset to reset the No. 1 filter plate 52 to be set to a spaced shape, so that the No. 1 filter hole 53 is automatically cleaned when the sewage is filtered and the No. 1 filter hole 53 is blocked, which greatly improves the service life of the equipment and reduces the number of maintenance times caused by blockage. At the same time, the cleaning process uses the source power of sewage for flushing, which greatly reduces the use of external power and saves the cost of sewage treatment. The flushed impurities are concentrated in the collection box 54.The staff can clean the impurities in the collection box 54 through the cleaning slot 57, which greatly reduces the maintenance difficulty of the equipment. By cooperating with the No. 1 filter plate 52 and the collection box 54, the impurities can be concentrated and gathered simultaneously when the sewage is treated, avoiding the problem that the conventional filter plates are easily blocked and need frequent manual cleaning. When the slider 59 moves downward, it squeezes the squeezing bag 519 at the bottom thereof, causing the internal air pressure of the squeezing bag 519 to increase, and finally transmits the internal air pressure to the telescopic plate 518 through the air guide pipe 520 connected thereto, causing the telescopic plate 518 to start to expand upward, that is, to start to push the push plate 517 on the top of the telescopic plate 518 to move upward, thereby driving the squeezing block 516 on the push plate 517 to move upward. , so that the cavity between the bottom of the No. 1 filter plate 52 and the guide plate 513 is squeezed, thereby providing an outward pressure for the No. 1 filter hole 53 on the No. 1 filter plate 52, thereby pushing the blockage in the No. 1 filter hole 53 outward, and further cleaning the upper surface of the No. 1 filter plate 52 in combination with the flushing of sewage, so that the No. 1 filter hole 53 is dredged while cleaning the impurities accumulated on the upper surface of the No. 1 filter plate 52, thereby greatly improving the cleaning effect. When the No. 1 filter hole 53 is not blocked or has been cleaned, the sewage will enter the guide plate 513 through the No. 1 filter hole 53, and will flow out from the bottom of the guide plate 513 through the oblique guidance of the guide plate 513, and finally flow into the cavity formed by the outer shell 1 and the folding plate 61. The silt in the sewage is precipitated inside, and the sewage after the silt precipitation finally spreads over the top of the folded plate 61 and flows to the water outlet 4 to be discharged, so that the sewage can automatically undergo further silt treatment after being filtered out by larger impurities, which greatly improves the sewage treatment effect. After the sewage flows into the internal cavity of the folded plate 61, it will directly flow on the guide plate 62 of the folded plate 61. At this time, the precipitated silt flows through the isolation groove 63 to the bottom cavity of the folded plate 61, and is blocked by the provided guide plate 62 to prevent the sewage from entering the folded plate 61 and directly acting on the precipitated silt, causing the silt to be repeatedly stirred to reduce the sedimentation effect. When the slider 59 moves downward, the connecting rod 610 will be driven downward by the driving rod 611, and then it will start to pull the two ends thereof. The slide bar 69 moves downward, and eventually begins to pull the sealing plate 65 connected to the top of the slide bar 69 downward, thereby opening the processing tank 64 at the bottom of the folded plate 61. The flow effect of the sewage is used to flush and clean the sediment at the bottom of the folded plate 61, and finally discharge it through the liquid outlet 68 on the side surface of the outer shell 1, thereby achieving the simultaneous cleaning of the sediment deposited at the bottom of the folded plate 61 while cleaning the No. 1 filter plate 52, greatly improving the automation level of the device and extending the working time of the device. At the same time, when the sealing plate 65 moves downward, it will simultaneously drive the buffer plate 66 to move downward to close the isolation tank 63, so that the isolation tank 63 is automatically closed when the processing tank 64 is opened, avoiding the problem of large-scale loss of sewage after filtering large impurities through the folded plate 61.
