Description
Technical Field
[0001] The utility model belongs to the technical field of sewage sludge separation, in particular to a river sludge separation and purification device. Background Art
[0002] With the acceleration of urbanization and the rise of industrialization, river pollution has become an increasingly prominent issue, impacting both the urban ecological environment and the quality of life of residents. River silt, a major source of water pollution, not only causes anaerobic fermentation, muddying and stinking water, but also contributes to the formation of black and odorous water and the growth of blue-green algae.
[0003] Currently, many urban rivers are facing serious silt pollution problems. According to statistics, the economic losses caused by river silt pollution amount to hundreds of billions of yuan. The organic matter deposited in the river silt will undergo anaerobic fermentation under anoxic conditions, producing a large amount of harmful gases and malodorous substances, seriously affecting the quality of life and health of surrounding residents. At the same time, the accumulation of silt will occupy the river space, affecting the water flow and navigation safety, and aggravating problems such as river siltation and rising water levels. Therefore, it is particularly important to carry out efficient and environmentally friendly separation and purification of river silt. When separating silt, the existing river silt separation and purification devices directly put the entire silt into the device for filtration. If the silt block is relatively dry, it will make it difficult for the silt block to disperse quickly through the filter plate; and the gravel and other impurities left on the filter plate will wrap a lot of silt, which cannot be filtered cleanly, resulting in some silt being unable to be collected. For this reason, it is necessary to propose a river silt separation and purification device with efficient filtration and cleaning. Utility Model Content
[0004] In order to solve the problem that the above-mentioned silt blocks are not easy to disperse through the filter plate, and the gravel and other impurities left on the filter plate wrap a lot of silt and cannot be filtered clean, resulting in some silt cannot be collected, the purpose of the utility model is to provide a river silt separation and purification device, which uses a high-pressure water gun and a stirring component in the tank body to flush the relatively dry silt to disperse the silt and a first filter screen is provided in the collection box, and the water flow in the separation component is thrown into the collection box again through the separation component to flush the gravel and other impurities wrapped in silt in the collection box multiple times.
[0005] In order to achieve the above-mentioned object, the technical solution of the utility model is as follows: a river sludge separation and purification device, comprising a tank body, a feed port is provided at the top of the tank body, a first opening and a third opening are provided on one side of the tank body, and a closing assembly for closing the first opening is provided on the side of the tank body close to the first opening;
[0006] A collection box is fixedly connected to the outer wall of the tank, the first opening and the third opening are both connected to the collection box, and a first filter is fixedly connected inside the collection box;
[0007] A third filter screen is fixedly connected to the third opening, and high-pressure water guns are fixedly connected to both sides of the inner wall of the tank;
[0008] A stirring assembly is fixedly connected to the tank body, the stirring assembly includes a stirring blade, the bottom of the stirring blade is fixedly connected to a stirring rod, the bottom wall of the tank body is fixedly connected to a motor, and the output shaft of the motor is coaxially fixedly connected to the other end of the stirring rod;
[0009] A filter plate is fixedly connected to the inside of the tank body. The filter plate is located below the high-pressure water gun and the stirring blade. A first through hole corresponding to the stirring rod is provided on the filter plate. A separation component for separating sludge by rotation is provided below the filter plate. The first opening is located above the filter plate, and the third opening is located below the filter plate and above the first filter screen.
[0010] The bottom of the collection box is connected to a first water outlet pipe, one end of the first water outlet pipe close to the collection box is fixedly connected to a water pump, and the end of the first water outlet pipe away from the collection box is connected to a high-pressure water gun close to one side of the collection box.
[0011] The basic scheme works as follows: First, the sludge to be separated and purified is fed into the device through the feed port and falls onto the filter plate. Simultaneously, the motor and high-pressure water gun are activated, and the sealing assembly is closed, sealing the first opening. Because the motor's output shaft is coaxially fixedly connected to the stirring rod, which is in turn fixedly connected to the stirring blades, motor rotation drives the stirring rod, which in turn drives the stirring blades to continuously stir. The sludge blocks are continuously flushed by spraying high-pressure water from the high-pressure water gun, and the sludge blocks are continuously stirred by the stirring blades to break up the sludge blocks. Since the sealing component closes the first opening, a closed space can be ensured when the high-pressure water gun and the stirring blades are used to flush and stir the sludge, and the sludge can be fully stirred and flushed. Therefore, under the mutual cooperation of the stirring blades and the high-pressure water gun, sludge with a particle size smaller than the filter particle size of the filter plate will pass through the filter plate and enter the separation component, while impurities wrapped in sludge with a particle size larger than the filter particle size of the filter plate will remain on the filter plate. At this time, the sealing component can be opened to connect the tank body with the collection box. At this time, after flushing and stirring, the impurities in the sludge blocks will enter the collection box through the first opening. Because the tank body is provided with a third opening, the third opening is located below the filter plate. When the separation component rotates, centrifugal force is generated. The centrifugal force will separate the sludge and water in the separation component, leaving the sludge in the separation component. At the same time, the water in the separation component can be thrown into the collection box through the third opening to further flush the impurities wrapped in sludge on the first filter screen. After the flushing is completed, the sludge and water mixture will be pumped through the first outlet pipe to the high-pressure water gun by the water pump and sprayed out again.
[0012] The beneficial effects of the basic solution are: 1. The high-pressure water gun can spray high-pressure water flow on the sludge blocks, so that the sludge blocks can be quickly dispersed. The high-speed stirring of the stirring blade can quickly stir the more stubborn sludge blocks into small particles, which is conducive to the flushing of the high-pressure water gun. The mutual cooperation between the stirring blade and the high-pressure water gun can quickly disperse the sludge blocks entering the tank through the feeding port, greatly improving the dispersion efficiency of the sludge blocks.
[0013] 2. Because the high-pressure water gun has been started when the sludge is put into the separation device, the high-pressure water gun can flush the sludge in an all-round way, and the stirring blades can stir the sludge in an all-round way, which improves the flushing and dispersion efficiency of the sludge blocks and has no flushing dead angles.
[0014] 3. A collection box is provided on one side of the tank body to collect the impurities remaining after the sludge blocks are dispersed. When the separation component rotates, centrifugal force will be generated. The centrifugal force will throw the water in the separation component into the collection box through the third opening to further rinse the impurities wrapped in sludge on the surface of the first filter screen, thereby playing a secondary cleaning role.
[0015] 4. The bottom of the collection box is connected to a first water outlet pipe. After flushing again, the sludge-water mixture can be recirculated through the first water outlet pipe and sprayed out of the high-pressure water gun, which is beneficial to improving the utilization rate of the sludge.
[0016] Furthermore, the filter plate is arranged in an inclined shape, with one end of the filter plate close to the collection box being lower than the other end.
[0017] The beneficial effect of the basic solution is that after the sludge on the filter plate is flushed and stirred, impurities such as gravel will remain on the filter plate. Since the filter plate is inclined, the impurities in the sludge will move toward the first opening into the collection box under the action of gravity, making it easier to collect the impurities.
[0018] Furthermore, the closing assembly includes a baffle, the area of the baffle is larger than the area of the first opening, a connecting rod is fixedly connected to the top of the baffle, a first extension opening is provided on the top of the tank body, the connecting rod extends to the outside of the tank body through the first extension opening, and a buckle is fixedly connected to the top of the tank body, and the buckle is located at the junction of the connecting rod and the tank body.
[0019] The beneficial effect of the basic scheme is: after the silt is put into the river silt separation and purification device, when the silt is not completely dispersed by the high-pressure water gun and the stirring blade, the baffle is used to block the first opening to prevent the incompletely dispersed silt from directly entering the collection box. A connecting rod is fixedly connected to the top of the baffle, and the connecting rod extends through the tank body to the outside of the tank body. A buckle is fixedly connected to the top of the tank body, and the buckle is located at the junction of the connecting rod and the tank body. Therefore, when the silt is dispersed, the baffle can be lifted by the connecting rod, and the connecting rod can be fixed by the buckle on the top of the tank body. The baffle is also lifted and fixed above the first opening. After the baffle is lifted, the silt impurities on the filter plate can smoothly enter the collection box.
[0020] Furthermore, an inverted cone-shaped collecting bucket is fixedly connected to the tank body, the top of the collecting bucket is located below the filter plate and the coverage area of the top of the collecting bucket is equal to the coverage area of the filter plate, and the bottom of the collecting bucket is rotatably connected to the separation assembly.
[0021] The beneficial effect of the basic solution is: because there is a collecting bucket fixedly connected to the tank body, the coverage area of the top of the collecting bucket is equal to the coverage area of the filter plate, so the sludge passing through the filter plate will enter the collecting bucket and enter the separation component through the collecting bucket, which can help all the sludge passing through the filter plate enter the separation component for dehydration.
[0022] Furthermore, the separation component includes a dehydration barrel, the top of which is rotatably connected to the bottom of the collecting bucket, the stirring rod passes through the bottom of the dehydration barrel and is fixedly connected to the bottom of the dehydration barrel, and the outer wall of the dehydration barrel is provided with a plurality of second through holes.
[0023] The beneficial effects of the basic scheme are: the output shaft of the motor is coaxially fixedly connected to the stirring rod, the stirring rod passes through the bottom of the dehydration barrel and is fixedly connected to the bottom of the dehydration barrel. Therefore, when the motor is started to drive the stirring rod to rotate, the stirring rod will drive the dehydration barrel to rotate together, and the dehydration barrel is driven to rotate together through the stirring rod; because a second through hole is provided on the surface of the dehydration barrel, centrifugal force will be generated when the dehydration barrel rotates. Due to the different densities of sludge and water, under the action of centrifugal force, the heavier sludge will remain in the dehydration barrel, while the lighter water can smoothly flow out of the tank through the second through hole through the action of centrifugal force, thereby separating the water and sludge.
[0024] Furthermore, one side of the bottom of the tank body is connected to a second water outlet pipe, the bottom wall of the tank body is inclined, and the side of the bottom wall of the tank body close to the second water outlet pipe is lower than the other side.
[0025] The beneficial effect of the basic scheme is that when the water flows out through the through holes on the surface of the dehydration barrel, it will enter the tank body. There is a water outlet at the bottom of the tank body and the bottom wall of the tank body is set to be inclined. The bottom wall of the tank body close to the water outlet is lower than the other side, so that the water in the tank body can flow out through the water outlet autonomously under the action of gravity.
[0026] Furthermore, a sludge output pipe is provided at the bottom of the dewatering barrel, and the sludge output pipe is rotatably connected to the dewatering barrel. A valve is provided between the sludge output pipe and the dewatering barrel, and a switch is provided on the valve. A second extension port corresponding to the switch is provided on the tank body, and the switch can extend outside the tank body through the second extension port. A second opening is provided at a position of the tank body corresponding to the sludge output pipe, and the other end of the sludge output pipe is connected to a storage box through the second opening, and the storage box is connected to a negative pressure pump on the side away from the tank body.
[0027] The beneficial effect of the basic solution is: since the dehydrated sludge is sticky, it is easy to stick to the inside of the dehydration barrel and is not easy to slide off on its own. Connecting a negative pressure pump on one side of the storage box can use the negative pressure suction created by the negative pressure pump to suck the sludge in the dehydration barrel into the storage box, making it convenient for the collection of the sludge and subsequent use.
[0028] Furthermore, a second filter is fixedly connected to the connection point between the negative pressure pump and the storage box.
[0029] The beneficial effect of the basic solution is: when the negative pressure pump absorbs silt, in order to reduce the amount of silt that directly enters the negative pressure pump and blocks the negative pressure pump, a second filter is fixedly connected to the connection between the negative pressure pump and the storage tank to ensure the normal operation of the negative pressure pump.

[0039] The closing assembly includes a baffle 4, the area of which is larger than the area of the first opening 3. A connecting rod 7 is welded to the top of the baffle 4. A first extension opening 25 is provided on the top of the tank body 1. The connecting rod 7 extends to the outside of the tank body 1 through the first extension opening 25. A buckle 8 is bolted to the top of the tank body 1, and the buckle 8 is located at the junction of the connecting rod 7 and the tank body 1.
[0040] An inverted cone-shaped collecting bucket 13 is bolted inside the tank body 1. The top of the collecting bucket 13 is located below the filter plate 12 and the coverage area of the top of the collecting bucket 13 is equal to the area of the filter plate 12. The bottom end of the collecting bucket 13 is rotatably connected to the separation assembly. The separation assembly includes a dehydration bucket 14. The top of the dehydration bucket 14 is rotatably connected to the bottom end of the collecting bucket 13 through a slider slot. The stirring rod 15 passes through the bottom end of the dehydration bucket 14 and is welded to the bottom of the dehydration bucket 14. The outer wall of the dehydration bucket 14 is provided with a plurality of second through holes. The inner bottom wall of the dewatering barrel 14 is inclined, and a sludge output pipe 22 is provided at the bottom of the dewatering barrel 14. The sludge output pipe 22 is rotatably connected to the dewatering barrel 14. The inner bottom wall of the dewatering barrel 14 near the sludge output pipe 22 is lower than the other side. A valve 16 is provided between the sludge output pipe 22 and the dewatering barrel 14. The valve 16 is provided with a switch 27. The tank body 1 is provided with a second extension opening 26 corresponding to the switch 27. The switch 27 can extend to the outside of the tank body 1 through the second extension opening 26. The other end of the sludge output pipe 22 passes through the second opening 17 and is connected to the storage box 18. The storage box 18 is connected to a negative pressure pump 19 on the side away from the tank body 1. The negative pressure pump 19 is connected to the storage box 18 and is bolted to a second filter 24.
[0041] One side of the bottom of the tank body 1 is connected to a second water outlet pipe 21 . The inner bottom wall of the tank body 1 is inclined, and the side of the inner bottom wall of the tank body 1 close to the second water outlet pipe 21 is lower than the other side.
[0042] The specific implementation process is as follows: first, the sludge block is put into the tank body 1 through the feeding port 9 at the top of the tank body 1, and the motor 20 and the high-pressure water gun 11 are started at the same time and the sealing component is closed to close the first opening 3. After closing the first opening 3, a closed space can be provided for the dispersion and flushing of the sludge, so that the sludge is stirred and flushed more fully. Since the output shaft of the motor 20 is connected to the stirring rod 15 by a coaxial sleeve, and the stirring rod 15 is welded to the stirring blade 10, the rotation of the motor 20 will drive the stirring rod 15 to rotate, and the stirring rod 15 will drive the stirring blade 10 to stir continuously. In the process of the sludge falling on the filter plate 12 under the action of gravity, the high-pressure water gun 11 can spray high-pressure water to flush the sludge block, and the stirring of the stirring blade 10 can also disperse the stubborn sludge block, so the high-pressure water gun 11 can flush the sludge in an all-round manner, and the stirring blade 10 can stir in an all-round manner, thereby improving the flushing and dispersion efficiency of the sludge block and eliminating the flushing dead angle. The high-pressure water gun 11 and the stirring blade 10 work together to disperse the sludge blocks fed into the tank body 1 through the feeding port 9 , and then the impurities wrapped in the sludge are retained above the filter plate 12 through the filter plate 12 .
[0043] An inverted cone-shaped collecting hopper 13 is bolted inside the tank body 1. The top of the collecting hopper 13 is located below the filter plate 12 and the coverage area of the top of the collecting hopper 13 is equal to the area of the filter plate 12. Therefore, all the sludge and water mixture passing through the filter plate 12 will enter the collecting hopper 13. The bottom of the collecting hopper 13 is rotatably connected to the separation assembly. The separation component includes a dewatering barrel 14, the top of the dewatering barrel 14 and the bottom of the collecting bucket 13 are rotatably connected through a slider slot, the stirring rod 15 passes through the bottom of the dewatering barrel 14 and is welded to the bottom of the dewatering barrel 14, and a number of second through holes are provided on the dewatering barrel 14, so when the motor 20 is started, the motor 20 will drive the stirring rod 15 to rotate, and the stirring rod 15 will then drive the dewatering barrel 14 to rotate. Due to the different densities of sludge and water, under the action of centrifugal force, the heavier sludge will remain in the dewatering barrel 14, while the lighter water can flow out of the tank body 1 smoothly through the second through holes through the action of centrifugal force, and the centrifugal force can be used to separate the mixture of sludge and water in the dewatering barrel 14.
[0044] When there are too many impurities on the filter plate 12, the operator can open the closing assembly, which includes a baffle 4. A connecting rod 7 is welded to the top of the baffle 4, and the connecting rod 7 extends to the outside of the tank body 1 through the first extension port 25. The top of the tank body 1 is bolted with a buckle 8, and the buckle 8 is located at the junction of the connecting rod 7 and the tank body 1. Therefore, when the operator pulls the connecting rod 7, the baffle 4 near the first opening 3 of the tank body 1 will be lifted, so that the tank body 1 is connected to the collection box 5. At this time, the buckle 8 can be closed, and the first connecting rod 7 and the baffle 4 can be fixed, so that the collection box 5 is connected to the inside of the tank body 1. The first filter screen 2 is bolted inside the collection box 5, and the inclined filter plate 12 can allow impurities wrapped in silt remaining on the top of the filter plate 12 to enter the first filter screen 2 in the collection box 5 under the action of gravity.
[0045] Since the dewatering barrel 14 generates centrifugal force when rotating, and the lighter water can pass through the second through hole smoothly due to the action of centrifugal force, the centrifugal force will throw the water in the dewatering barrel 14 through the second through hole and through the third opening 28 into the collection box 5 to re-rinse the impurities wrapped in silt on the first filter screen 2 in the collection box 5. Since the water flow has a sufficient speed under the action of centrifugal force, the silt covering the surface of the impurities can be washed away. After the washing is completed, the mixture of silt and water will pass through the first water outlet pipe 6. Since the first water outlet pipe 6 is connected to the water pump 23 at one end close to the collection box 5, and the other end of the first water outlet pipe 6 is connected to the high-pressure water gun 11, the mixture of silt and water passing through the first water outlet pipe 6 will be re-pumped to the high-pressure water gun 11 under the action of the water pump 23, and re-enter the interior of the tank body 1 for washing, thereby improving the separation and purification degree of the device.
[0046] After the water in the sludge in the dewatering barrel 14 is separated by centrifugal force, the water that does not enter the collection box 5 through the third opening 28 will enter the interior of the tank body 1. Since the inner bottom wall of the tank body 1 is inclined, the inner bottom wall of the tank body 1 on the side closest to the second water outlet pipe 21 is lower than the other side, so the water entering the tank body 1 will automatically flow to the second water outlet pipe 21 under the action of gravity, facilitating subsequent use.
[0047] After the sludge inside the dewatering barrel 14 is dehydrated, only sludge remains in the dewatering barrel 14. When the switch 27 is turned on, the valve 16 between the dewatering barrel 14 and the sludge conveying pipeline will be opened, and then the negative pressure pump 19 will be turned on. The negative pressure suction force generated by the negative pressure pump 19 will be used to suck the sludge in the dewatering barrel 14 into the storage box 18. A second filter screen 24 is fixedly connected to the connection between the negative pressure pump 19 and the storage box 18. The second filter screen 24 can filter the sludge entering the storage box 18 and prevent it from being sucked into the negative pressure pump 19, thereby ensuring the smooth operation of the negative pressure pump 19.
