Description

Technical Field

[0001] This invention relates to the field of environmental engineering technology, and in particular to a mud-water separation device for river and lake bottom sediments used in mine restoration. Background Technology

[0002] The sludge produced during dredging often has a high water content, making it difficult to use directly. It also contains toxic and harmful substances that can cause significant environmental pollution and cannot be discharged directly. Therefore, the sludge needs to be dehydrated. Dehydration reduces the volume of the sludge and greatly increases its solid content, allowing for the use of various effective solids treatment methods. Sludge dehydration effectively prevents secondary pollution, making it safer and more environmentally friendly.

[0003] Existing river and lake sediment separation devices have the following problems during use:

[0004] 1. Existing devices are not convenient for collecting dewatered sludge fully during use, which can easily cause sludge to clog the dewatering device, preventing the water in the sludge from being discharged and resulting in poor sludge-water separation.

[0005] 2. Due to the adhesive properties of sludge, the dewatered sludge will adhere to the inside of the dewatering device. Although some existing devices will install vibration devices to shake off the sludge adhering to the inside of the dewatering device, the existing devices cannot fully shake off the adhered sludge during use. The vibration force generated by the vibration device is relatively concentrated and the vibration range is limited. The vibration force generated in some local areas is relatively small, resulting in a weak effect of shaking off the sludge. Moreover, if more vibration devices are installed, the cost will be high. Summary of the Invention

[0006] To overcome the shortcomings of existing devices, such as difficulty in fully collecting dehydrated sludge, easy blockage by sludge leading to water discharge, and inability to fully shake off adhered sludge, resulting in poor mud-water separation, this invention provides a mud-water separation device for river and lake bottom sediments used in mine restoration. This device can more fully collect dehydrated sludge, prevent blockage, allow for smoother water discharge, and expand the vibration area to more effectively shake off adhered sludge, thereby improving the mud-water separation effect.

[0007] The technical solution of this invention is: a mud-water separation device for river and lake bottom sediment in mine restoration, comprising a base with a mud discharge port for discharging dewatered sludge; a housing fixedly connected to the base above the mud discharge port; a one-way valve fixedly connected to the top of the housing with a feed pipe fixedly connected to it; a filter frame fixedly connected to one side of the base and to the housing; a drainage trough frame fixedly connected to the filter frame; a baffle slidably connected to the bottom of the housing in contact with the mud discharge port; a fixing rod fixedly connected to the upper side of the housing; a dewatering component on the base for separating mud and water; a discharge component connected to the dewatering component for discharging dewatered sludge.

[0008] In one embodiment, the housing is a frame structure.

[0009] In one embodiment, the feed tube is a hollow structure.

[0010] In one embodiment, the bottom of the drainage trough frame is provided with a discharge pipe, which is used to discharge water squeezed out of the sludge.

[0011] In one embodiment, the dehydration assembly includes an electric push rod fixedly connected to the base, a push plate fixedly connected to the telescopic rod of the electric push rod, a squeezing plate slidably connected to the housing, the squeezing plate slidably connected to the push plate, and a plurality of compression springs connecting the push plate and the squeezing plate.

[0012] In one embodiment, the extrusion plate and the filter screen frame are on the same horizontal line, and the extrusion plate and the filter screen frame are used together to extrude and dewater the sludge.

[0013] In one embodiment, the discharge assembly includes a pressure rod fixedly connected to the push plate and located above the electric push rod. A button is fixedly connected to the lower end of the fixed rod. An electric slide rail is fixedly connected to the base, and a slider is slidably connected to the electric slide rail. The slider is fixedly connected to the baffle, and the electric slide rail is electrically connected to the button.

[0014] In one embodiment, a cleaning component is also included, which is disposed on the baffle plate. The cleaning component is used to scrape off the sludge adhering to the filter screen frame. The cleaning component includes mounting rods, two of which are fixedly connected to the baffle plate and are symmetrically arranged. A pusher frame is slidably connected to the housing, and a connecting rod is rotatably connected between the two mounting rods and the pusher frame. The two connecting rods are symmetrically arranged.

[0015] In one embodiment, a vibration assembly is further included, which is disposed on the housing and is used to shake off sludge adhering to the housing. The vibration assembly includes racks, two of which are fixedly connected to the housing and are symmetrically arranged. Two meshing gears are rotatably connected to the pusher frame, and the meshing gears mesh with the racks. Two rope winders are rotatably connected to the pusher frame, and the rope winders are fixedly connected to the meshing gears. A pull rope is fixedly connected to the rope winder, and the pull rope is wound around the rope winder and passes through the housing. Two slotted rods are fixedly connected to the housing, and movable blocks are slidably connected to each of the two slotted rods. The movable blocks are connected to the other end of the pull rope. Vibrators are fixedly connected to the bottom of each of the two movable blocks, and the two vibrators are slidably connected to the housing.

[0016] In one embodiment, both slotted rods are vertically arranged and symmetrically arranged.

[0017] The beneficial effects are as follows: 1. This invention is equipped with a push plate, a squeezing plate, and a filter screen frame. The push plate is driven by an electric push rod to slide back and forth. As the push plate continues to move, it pushes the squeezing plate to slide. The sliding of the squeezing plate will squeeze the sludge inside the shell. In this way, the squeezing plate and the filter screen frame can squeeze the sludge together, squeeze out the water in the sludge, and dehydrate the sludge. The water will be discharged from the filter screen frame into the drainage trough frame, and then discharged into the next process through the drainage trough frame. The sludge inside the shell after dehydration will enter the next process through the sludge discharge port of the base. This process is repeated. In this way, the above operation can quickly separate the mud and water in the bottom mud of rivers and lakes, effectively increase the solid content of the sludge, reduce the pollution of water bodies by sludge, and thus purify the water.

[0018] 2. This invention includes mounting rods, connecting rods, and a pusher frame. A baffle slides back and forth, causing two mounting rods to move back and forth. The reciprocating movement of the mounting rods causes the connecting rods to swing back and forth. The swinging of the two connecting rods causes the pusher frame to slide downwards. As the pusher frame slides downwards, it contacts the filter screen frame and scrapes away any residual sludge. The reciprocating swing of the two connecting rods causes the pusher frame to return to its original position. This allows the pusher frame to more thoroughly scrape away sludge from the filter screen frame, preventing sludge blockage and allowing for smoother water discharge, thus effectively improving the mud-water separation effect.

[0019] 3. This invention is equipped with a meshing gear, a pull rope, and a vibrator. The pusher frame slides up and down, driving the meshing gear and the rope winder to move up and down. The rotation of the rope winder unwinds the pull rope, causing the movable block to slide downwards. The downward movement of the movable block drives the vibrator to slide downwards, which vibrates the shell and shakes off the sludge adhering to the inner wall, preventing the sludge from clogging the shell and causing cleaning difficulties. The meshing gear resets upwards and reverses, driving the rope winder to reverse as well. The reverse movement of the rope winder winds the pull rope, thus allowing the vibrator to slide up and down, expanding the vibration range and more evenly vibrating the shell. This avoids weak vibration in some areas of the shell, which would make it difficult to shake off the sludge, thereby more effectively improving the mud-water separation effect.

Detailed Implementation

[0029] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0030] Example 1: A mud-water separation device for river and lake bottom sediments used in mine restoration, such as... Figures 1-7 As shown, the system includes a base 1 with a sludge discharge port for discharging dewatered sludge. A housing 2 is welded to the base 1 above the sludge discharge port. A one-way valve 3 is bolted to the top of the housing 2, and a feed pipe 4 is bolted to the one-way valve 3. A filter screen frame 5 is bolted to one side of the base 1 for filtering water from the sludge. The filter screen frame 5 is fixedly connected to the housing 2, and a drainage trough frame 6 is bolted to the filter screen frame 5. A baffle 7 is slidably connected to the bottom of the housing 2. A fixing rod 8 is welded to one side of the upper part of the housing 2. A dewatering assembly is provided on the base 1 for separating mud and water. A discharge assembly is provided on the dewatering assembly and connected to it for discharging the dewatered sludge.

[0031] The shell 2 is a frame structure.

[0032] The feed pipe 4 is a hollow structure.

[0033] The bottom of the drainage trough frame 6 is provided with a discharge pipe, which is used to discharge the water squeezed out of the sludge.

[0034] The dewatering assembly includes an electric push rod 91, which is bolted to the base 1. A push plate 92 is bolted to the telescopic rod of the electric push rod 91. A squeezing plate 93 is slidably connected to the housing 2. The squeezing plate 93 is used to squeeze the sludge for dewatering. The squeezing plate 93 is slidably connected to the push plate 92. Four compression springs 94 are connected between the push plate 92 and the squeezing plate 93 via hooks. All four compression springs 94 are sleeved on the squeezing plate 93.

[0035] The extrusion plate 93 and the filter screen frame 5 are on the same horizontal line. The extrusion plate 93 and the filter screen frame 5 are used together to extrude and dewater the sludge.

[0036] The discharge assembly includes a pressure rod 101, which is welded to the push plate 92 and located above the electric push rod 91. A button 102 is bolted to the lower end of the fixed rod 8. An electric slide rail 103 is bolted to the base 1, and a slider 104 is slidably connected to the electric slide rail 103. The slider 104 is fixedly connected to the baffle 7. The electric slide rail 103 is electrically connected to the button 102, which is used to activate the slider 104.

[0037] Initially, baffle 7 blocks the sludge discharge port of base 1. In actual application, the operator first introduces sludge into housing 2 through feed pipe 4. After entering housing 2, the sludge comes into contact with both extrusion plate 93 and filter screen frame 5. Then, the operator activates electric push rod 91. The telescopic rod of electric push rod 91 continuously extends or retracts, causing push plate 92 to slide back and forth. When push plate 92 moves closer to housing 2, it pushes extrusion plate 93 to slide through compression spring 94. Compression spring 94 is compressed, and the sliding of extrusion plate 93 extrudes the sludge inside housing 2. This allows extrusion plate 93 and filter screen frame 5 to extrude the sludge together, squeezing out the water from the sludge and dewatering it. The water is discharged from filter screen frame 5 into drainage trough frame 6, and then discharged into the next process through discharge pipe of drainage trough frame 6. At the same time, the movement of push plate 92 causes pressure rod 101 to move. The movement of pressure rod 101 contacts button 102. Continuing to move will press button 102. Pressing button 102 will activate slider 104 to slide back and forth. Sliding slider 104 will drive baffle 7 to slide back and forth. When baffle 7 slides closer to the housing 2, it will no longer block the mud discharge port of base 1. The sludge in the housing 2 after dewatering will enter the next process through the mud discharge port of base 1. When baffle 7 resets, it will block the mud discharge port of base 1 again. When push plate 92 resets away from the housing 2, it will drive pressure rod 101 to reset. When pressure rod 101 resets, it will disengage from button 102. Button 102 closes, causing slider 104 to close. The reset of compression spring 94 will drive extrusion plate 93 to reset. This process is repeated. Thus, through the above operation, mud and water can be quickly separated from river and lake bottom mud, effectively increasing the solid content of sludge, reducing sludge pollution of water bodies, and thus purifying the water body. After the mud and water separation is completed, the staff will turn off the electric push rod 91.

[0038] Example 2: Based on Example 1, such as Figures 2-7 As shown, it also includes a cleaning component, which is disposed on the baffle 7. The cleaning component is used to scrape off the sludge adhering to the filter screen frame 5. The cleaning component includes two mounting rods 111, which are welded to the baffle 7 and are symmetrically arranged. A pusher frame 112 is slidably connected to the housing 2. A connecting rod 113 is rotatably connected between the two mounting rods 111 and the pusher frame 112, and the two connecting rods 113 are symmetrically arranged.

[0039] As the baffle 7 slides back and forth, it drives the two mounting rods 111 to move back and forth. The reciprocating movement of the mounting rods 111 drives the connecting rods 113 to swing back and forth. The swinging of the two connecting rods 113 drives the pusher frame 112 to slide downward. The pusher frame 112 slides downward and contacts the filter screen frame 5, scraping off the residual sludge on the filter screen frame 5. This sludge will fall downward and be discharged from the sludge discharge port of the housing 2. The swinging reset of the two connecting rods 113 will drive the pusher frame 112 to reset upward. This allows the pusher frame 112 to slide up and down more thoroughly to scrape off the sludge on the filter screen frame 5, preventing the sludge from clogging the filter screen frame 5, and allowing the water to be discharged more smoothly, thereby effectively improving the mud-water separation effect.

[0040] Example 3: Based on Example 2, such as Figures 1-8 As shown, it also includes a vibration assembly mounted on the housing 2. The vibration assembly is used to shake off the silt adhering to the housing 2. The vibration assembly includes two racks 121, both of which are bolted to the housing 2 and are symmetrically arranged. Two meshing gears 122 are rotatably connected to the pusher frame 112, and the meshing gears 122 mesh with the racks 121. Two rope winders 123 are rotatably connected to the pusher frame 112, and the rope winders 123 mesh with the meshing gears 121. A wheel 122 is fixedly connected, and a pull rope 124 is fixedly connected to the rope winder 123. The pull rope 124 is wound around the rope winder 123 and passes through the housing 2. Two slotted rods 125 are connected to the housing 2 by rivets. Movable blocks 126 are slidably connected to the two slotted rods 125. The movable blocks 126 are connected to the other end of the pull rope 124. Vibrators 127 are bolted to the bottom of the two movable blocks 126. The two vibrators 127 are slidably connected to the housing 2.

[0041] Both slotted rods 125 are vertically arranged and symmetrically arranged.

[0042] Initially, the workers activated the two vibrators 127. As the pusher frame 112 slid up and down, it caused the meshing gear 122 and the rope winder 123 to move up and down together. As the meshing gear 122 moved downwards, it rotated along the rack 121. This rotation of the meshing gear 122 caused the rope winder 123 to rotate, which in turn unwound the pull rope 124. This unwinding of the pull rope 124 caused the movable block 126 to slide downwards. The downward movement of the movable block 126 caused the vibrator 127 to slide downwards, vibrating the housing 2 and dislodging the silt adhering to the inner wall of the housing 2. To prevent sludge from clogging the shell 2 and causing cleaning difficulties, the meshing gear 122 will reverse while resetting upwards. The reverse rotation of the meshing gear 122 will drive the rope winder 123 to reverse, and the reverse rotation of the rope winder 123 will wind up the pull rope 124. The winding of the pull rope 124 will drive the movable block 126 and the vibrator 127 to reset upwards, thereby allowing the vibrator 127 to slide up and down to expand the vibration range and more fully shake off the adhering sludge. This avoids the situation where the vibration force in some parts of the shell 2 is too small to shake off the sludge, thus more effectively improving the mud-water separation effect. After the mud-water separation is completed, the staff will turn off the vibrator 127.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
