Description

Technical Field

[0001] The invention relates to the technical field of thickeners, and in particular to a thickener flocculant accelerated solid-liquid separation device and a separation method. Background Art

[0002] A thickener is a solid-liquid separation equipment widely used in the industrial field. It is mainly used to treat suspensions containing solid particles and achieve separation of solids and liquids. It plays an important role in many industries such as mining, chemical industry, and environmental protection. When performing solid-liquid separation, traditional thickeners often have problems such as uneven addition of flocculants, insufficient mixing, easy scaling of the inner wall of the treatment pool, and inconvenient sludge cleaning.

[0003] Uneven addition of flocculants will result in part of the slurry not being able to fully contact the flocculants, affecting the flocculation effect, and thus reducing the efficiency and quality of solid-liquid separation. At the same time, calcium and magnesium ions in the slurry are prone to form scale on the inner wall of the treatment tank. If not cleaned in time, it will not only affect the normal operation of the equipment, but also reduce the effective volume of the treatment tank. In addition, if the sludge precipitated at the bottom of the treatment tank cannot be effectively gathered and discharged in time, it will also affect the continuity and stability of the entire solid-liquid separation process.

[0020] Beneficial Effects

[0021] The present invention provides a thickener flocculant accelerated solid-liquid separation device and a separation method. Compared with the prior art, it has the following beneficial effects:

[0022] 1. The thickener flocculant accelerates solid-liquid separation device and separation method. The forward and reverse rotation of the power motor can control the movement of the rotating drum and the piston plate, so that the flocculant can be sprayed into the slurry in a specific way. The large-aperture one-way valve on the top sprays more flocculants to ensure that the unprecipitated slurry fully contacts the flocculant. The small-aperture one-way valve on the bottom adds a small amount of flocculant to further optimize the precipitation effect. Subsequently, the rapid rotation of the stirring drum can quickly and evenly mix the flocculant and the slurry, thereby improving the flocculation effect and accelerating the solid-liquid separation process.

[0023] 2. The thickener flocculant accelerates the solid-liquid separation device and separation method. The scraper in the cleaning component can fit closely to the inner wall of the treatment tank when the power motor rotates forward, effectively scraping off the sludge and calcium and magnesium ion scaling attached to the inner wall. The scraped impurities enter the storage cylinder through the storage groove. Under the action of the spiral blades and water flow, the impurities finally fall above the precipitated sludge below, avoiding interference with the slurry precipitation above, while ensuring the cleanliness of the inner wall of the treatment tank, maintaining the normal operation of the equipment, and extending the service life of the equipment.

[0024] 3. The thickener flocculant accelerates the solid-liquid separation device and separation method. The reducer controls the slow rotation of the bottom rotating rod, driving the combing plate to gather the mud settled on the outside of the bottom of the treatment tank to the inside, and finally discharge it through the sludge outlet, which not only ensures the smooth discharge of the sludge, but also does not affect the sedimentation effect of the slurry due to excessive stirring, thereby improving the stability of the entire solid-liquid separation device.

[0040] A sludge outlet 10 is fixedly installed at the bottom of the treatment tank 1, an overflow trough 8 is fixedly installed on the inner wall of the top wall of the treatment tank 1, a clean water outlet 9 is fixedly installed on the outer edge of the treatment tank 1, and the connection between the clean water outlet 9 and the inside of the treatment tank 1 is located inside the overflow trough 8, and a slurry feeding port 7 is fixedly installed at the bottom of the top platform 6.

[0041] In this embodiment, when the power motor 22 rotates, the power motor 22 rotates forward to drive the first crown gear 23 below to rotate, and the first crown gear 23 can drive the second crown gear 24 meshing below to rotate synchronously. The support plate 25, the spring 26, and the rotating ring 27 rotate synchronously with the second crown gear 24. The second crown gear 24 drives the rotating cylinder 31 below to rotate forward. The rotating cylinder 31 rotates forward to drive the piston plate 310 and the processing box 32 to rotate. The processing box 32 rotates around the supporting ring 33 below, driving the outer mixing cylinder 35 to rotate. When the power motor 22 is reversed, the teeth of the first crown gear 23 and the second crown gear 24 will squeeze each other, so that the second crown gear 24 can be squeezed downward. After the downward squeezing, the spring 26 is compressed. When the tooth tips of the two crown gears pass each other, the second crown gear 24 is reset under the action of the spring 26. In this way, the power motor 22 is reversed, and the second crown gear 24 and the rotating cylinder 31 move back and forth linearly up and down.

[0042] Reference Figures 1 to 10 In one aspect of the present embodiment, the connection direction of the first one-way valve 36 is from the inside of the mixing drum 35 to the outside, the aperture of the first one-way valve 36 above the mixing drum 35 is larger than the aperture below, and the connection point between the mixing drum 35 and the processing box 32 is located below the piston plate 310.

[0043] The communication direction of the second one-way valve 311 is from the top to the bottom of the piston plate 310. The interior of the rotating cylinder 31 is connected to the bottom of the piston plate 310 through the second one-way valve 311. The rotating cylinder 31 movably penetrates the inner top of the processing box 32. A connecting box 37 is fixedly installed at the bottom of the top platform 6. A feed pipe 38 is fixedly installed on the side of the connecting box 37. The rotating cylinder 31 movably penetrates the inside of the connecting box 37. A connecting groove 39 is opened on the side wall of the rotating cylinder 31. The connecting groove 39 is located inside the connecting box 37. A support rod 34 is fixedly installed on the inner wall of the processing pool 1. A support ring 33 is fixedly installed between the inner ends of the support rod 34. The processing box 32 is rotatably connected to the top of the support ring 33.

[0044] In this embodiment, the slurry is injected into the treatment tank 1 through the slurry feeding port 7, and the feed pipe 38 extends to the outside to transport the flocculant in the flocculant storage box to the inside of the connecting box 37. After the flocculant is transported to the inside of the connecting box 37, it will enter the inside of the rotating cylinder 31 through the connecting groove 39. When it is necessary to add flocculant, the power motor 22 is reversed. After the reversal, the rotating cylinder 31 moves up and down to drive the internal piston plate 310 to move up and down. When the piston plate 310 moves up, the flocculant above can be sucked into the bottom of the piston plate 310 through the second one-way valve 311. When the piston plate 310 moves down, the flocculant below can be sprayed out through the first one-way valve 36 on the upper and lower sides of the mixing cylinder 35. The amount sprayed from the top is greater than the amount from the bottom due to the aperture. Through this spraying method, the flocculant can be diffused into the upper slurry that needs to be precipitated more quickly, and the flocculant sprayed from the top A large output can ensure that most of the slurry that has not been precipitated at the top can be repeatedly mixed with the flocculant, and the slurry that has been precipitated at the bottom can further ensure the precipitation effect by adding a small amount of flocculant; when the flocculant is added to a certain amount, the power motor 22 rotates forward to drive the rotating cylinder 31 to rotate forward. During forward rotation, the piston plate 310 cannot move back and forth up and down, and the addition of the flocculant stops, and the rotating cylinder 31 drives the stirring cylinder 35 to rotate. The slurry is stirred by the rotation of the stirring cylinder 35, so that the flocculant sprayed into the slurry is quickly mixed. After mixing for a period of time, the power motor 22 is stopped. At this time, the slurry mixed with the flocculant at the top can be precipitated. During precipitation, the slurry feeding port 7 continues to add slurry. When a certain amount of slurry is accumulated again at the top, the above operation is repeated to achieve flocculant addition, stirring and mixing after addition, and static precipitation after mixing.

[0045] Reference Figures 1 to 10 In one aspect of the present embodiment, the processing assembly 5 includes a reducer 51, which is fixedly mounted on the bottom of the support ring 33, the input end of the reducer 51 is fixedly mounted on the bottom of the processing box 32, the output end of the reducer 51 is fixedly mounted with a bottom rotating rod 52, the outer side of the bottom rotating rod 52 is fixedly mounted with a swing rod 53, the outer side of the swing rod 53 is fixedly mounted with a combing plate 54, and the swing rod 53 and the combing plate 54 are attached to the inner bottom wall of the processing pool 1.

[0046] In this embodiment, the precipitated slurry at the bottom will fall downward to the bottom of the treatment tank 1 and be discharged through the sludge outlet 10. The slurry adding point at the top is located near the middle of the treatment tank 1. The clean water after external precipitation overflows when the slurry is continuously added. The overflowing clean water will enter the overflow trough 8 for collection and be discharged through the clean water outlet 9. When the power motor 22 rotates forward, the treatment box 32 rotates and drives the bottom rotating rod 52 to rotate through the reducer 51, and the speed of the bottom rotating rod 52 is reduced by the reducer 51, so that the speed of the bottom rotating rod 52 is slower. The rotation of the bottom rotating rod 52 drives the swing rod 53 and the combing plate 54 to move along the bottom of the treatment tank 1, and the combing plate 54 is tilted toward the inside. The movement of the combing plate 54 can gather the slurry at the outside of the bottom of the treatment tank 1 to the inside, and finally discharge it through the sludge outlet 10, and the slower rotating swing rod 53 and combing plate 54 will not affect the precipitation of the slurry and will not re-mix the precipitated sludge with water on a large scale, thereby ensuring the sludge discharge effect.

[0047] Reference Figures 1 to 10 In one aspect of the present embodiment, the cleaning assembly 4 includes a fixing ring 41, which is fixedly mounted on the outside of the rotating cylinder 31, a connecting rod 42 is fixedly mounted on the outside of the fixing ring 41, a storage cylinder 43 is fixedly mounted on the outside of the connecting rod 42, a scraper 45 is fixedly mounted on the outside of the storage cylinder 43, and the scraper 45 is attached to the inner wall of the treatment pool 1.

[0048] A storage groove 44 is provided on the side wall of the storage cylinder 43, and the storage groove 44 is located on the side of the scraper 45. A spiral blade 46 is fixedly installed inside the storage cylinder 43. A discharge groove 47 is provided on the side wall of the storage cylinder 43, and the discharge groove 47 and the storage groove 44 are respectively located on both sides of the storage cylinder 43. A metal mesh plate is fixedly installed on the outside of the storage cylinder 43 and on the outside of the discharge groove 47.

[0049] In this embodiment, when the power motor 22 rotates forward, the connecting rod 42 can be driven to rotate through the fixing ring 41, and the connecting rod 42 rotates to drive the external storage barrel 43 to rotate, and drives the scraper 45 to move along the inner wall of the treatment tank 1. The sludge attached to the inner wall of the treatment tank 1 and the scaling generated by the calcium and magnesium ions in the slurry can be scraped off by the scraper 45. After scraping, the sludge impurities scraped off by the continuous rotation of the storage barrel 43 to the left and right will enter the storage barrel 43 through the storage groove 44 together with the water. After entering, the different water will be discharged through the discharge groove 47. When discharged, the sludge is blocked by the metal mesh plate and cannot be discharged. The water flow enters the storage barrel 43 together with the sludge. As the storage barrel 43 continues to move, it will produce The water flow will move along the internal spiral blade 46, and the external water flow will continue to enter the storage cylinder 43 through the storage groove 44, so that the internal water flow will move downward in a spiral along the spiral blade 46, and finally be discharged from the bottom of the storage cylinder 43 to the top of the sludge after sedimentation below, and the impurities and dirt after cleaning will be collected and guided by the storage cylinder 43 to ensure that the dirt cleaned will not affect the sedimentation of the slurry above; and when the power motor 22 is reversed, the reciprocating up and down movement of the rotating cylinder 31 drives the fixing ring 41, the connecting rod 42 and the storage cylinder 43 to vibrate up and down, and the vibration force of the reciprocating up and down storage cylinder 43 can clean the impurities and dirt that are not completely discharged from the spiral blade 46.

[0050] This embodiment also discloses a separation method of a thickener flocculant accelerated solid-liquid separation device, comprising the following steps:

[0051] Step 1: The slurry is transported to the inside of the treatment tank 1 through the slurry feeding port 7, and the flocculant is transported to the inside of the connecting box 37 through the feeding pipe 38. The rotating cylinder 31 is reciprocated up and down by the reverse rotation of the power motor 22, and the flocculant is sprayed into the slurry inside the treatment tank 1 through the upper and lower first one-way valves 36;

[0052] Step 2: After the flocculant is sprayed, the forward power motor 22 drives the processing box 32 and the stirring drum 35 to rotate rapidly, and the slurry and the flocculant are quickly stirred and mixed by the rotation of the stirring drum 35 to achieve slurry sedimentation;

[0053] Step 3: When the power motor 22 rotates forward, the reducer 51 drives the bottom rotating rod 52 to rotate slowly, and the bottom rotating rod 52 rotates slowly to drive the swing rod 53 and the combing plate 54 to rotate, and the precipitated sludge in the mud box outlet 10 can be gathered by the combing plate 54;

[0054] Step 4: When the power motor 22 rotates forward, the scaling impurities attached to the inner wall of the treatment tank 1 are scraped off by the scraper 45 and stored in the storage cylinder 43 through the storage groove 44. When the power motor 22 rotates reversely, the storage cylinder 43 shakes up and down, which can speed up the falling speed of the scaling impurities in the storage cylinder 43, and the impurities in the storage cylinder 43 will not affect the normal precipitation outside.

[0055] Step 5: During sedimentation, clean water overflows into the overflow tank 8 and is discharged through the clean water outlet 9, and sludge is discharged through the sludge outlet 10 below, thereby achieving solid-liquid separation.

[0056] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0057] Working principle: When the power motor 22 rotates, the power motor 22 rotates forward to drive the first crown gear 23 below to rotate, and the first crown gear 23 can drive the second crown gear 24 meshing below to rotate synchronously. The support plate 25, the spring 26, and the rotating ring 27 rotate synchronously with the second crown gear 24. The second crown gear 24 drives the rotating cylinder 31 below to rotate forward. The rotating cylinder 31 rotates forward to drive the piston plate 310 and the processing box 32 to rotate. The processing box 32 rotates around the supporting ring 33 below, driving the outer mixing cylinder 35 to rotate. When the power motor 22 reverses, the teeth of the first crown gear 23 and the second crown gear 24 will squeeze each other, so that the mixing cylinder 35 can be rotated. The second crown gear 24 is squeezed downward, and the spring 26 is compressed after the downward squeezing. When the tooth tips of the two crown gears pass each other, the second crown gear 24 is reset under the action of the spring 26, and the power motor 22 is reversed in this way, and the second crown gear 24 and the rotating drum 31 move back and forth linearly up and down; the slurry is injected into the processing tank 1 through the slurry feeding port 7, and the feeding pipe 38 extends to the outside to transport the flocculant in the flocculant storage box to the inside of the connecting box 37. After the flocculant is transported to the inside of the connecting box 37, it will enter the inside of the rotating drum 31 through the connecting groove 39. When flocculant needs to be added, the power motor 22 is reversed, and the rotating drum 31 moves up and down after the reversal. The repeated movement drives the internal piston plate 310 to move up and down. When the piston plate 310 moves up, the flocculant above can be sucked into the bottom of the piston plate 310 through the second one-way valve 311. When the piston plate 310 moves down, the flocculant below can be sprayed out through the first one-way valve 36 on the upper and lower sides of the mixing drum 35. The amount sprayed from the top is greater than the amount from the bottom due to the aperture. This spraying method can more quickly diffuse the flocculant into the upper slurry that needs to be precipitated, and the large amount of spraying from the top can ensure that most of the slurry that has not been precipitated above can be repeatedly mixed with the flocculant, and the slurry that has been precipitated below can be further precipitated by adding a small amount of flocculant. Effect: When a certain amount of flocculant is added, the power motor 22 rotates forward, driving the rotating cylinder 31 to rotate forward. During the forward rotation, the piston plate 310 cannot move up and down, and the addition of the flocculant stops. The rotating cylinder 31 drives the stirring cylinder 35 to rotate. The stirring cylinder 35 rotates to stir the slurry, so that the flocculant sprayed into the slurry is quickly mixed. After mixing for a period of time, the power motor 22 is stopped. At this time, the slurry mixed with the flocculant on the top can be precipitated. During precipitation, the slurry is continuously added to the slurry feeding port 7. When a certain amount of slurry is accumulated again on the top, the above operation is repeated to achieve the addition of flocculant, stirring and mixing after addition, and static precipitation after mixing.The precipitated slurry at the bottom will fall down to the bottom of the treatment tank 1 and be discharged through the sludge outlet 10. The slurry addition point at the top is located near the middle of the treatment tank 1. The clean water after external precipitation overflows when the slurry is continuously added. The overflowing clean water enters the overflow tank 8 for collection and is discharged through the clean water outlet 9. When the power motor 22 rotates forward, the treatment box 32 rotates and drives the bottom rotating rod 52 to rotate through the reducer 51, and the speed of the bottom rotating rod 52 is reduced by the reducer 51, so that the speed of the bottom rotating rod 52 is slower, and the swing rod 53 and the combing plate 5 are driven by the rotation of the bottom rotating rod 52. 4 moves along the bottom of the treatment tank 1, and the combing plate 54 is inclined toward the inside. The movement of the combing plate 54 can gather the mud at the outside of the bottom of the treatment tank 1 to the inside, and finally discharge it through the mud outlet 10. The swing rod 53 and the combing plate 54 with a slower rotation speed will not affect the sedimentation of the pulp and will not re-mix the settled sludge with water on a large scale, thereby ensuring the sludge discharge effect. When the power motor 22 rotates forward, the connecting rod 42 can be driven to rotate through the fixing ring 41, and the rotation of the connecting rod 42 drives the external storage barrel 43 to rotate, and drives the scraper 45 to rotate along the inside of the treatment tank 1. The wall moves, and the sludge attached to the inner wall of the treatment tank 1 and the scaling caused by calcium and magnesium ions in the slurry can be scraped off by the scraper 45. After scraping, the sludge impurities scraped off by the storage cylinder 43 will enter the storage cylinder 43 through the storage groove 44 together with the water. After entering, the different water will be discharged through the discharge groove 47. When the sludge is discharged, it is blocked by the metal mesh plate and cannot be discharged. The water flow enters the storage cylinder 43 together with the sludge. When the storage cylinder 43 continues to move, a water flow will be generated inside the storage cylinder 43. The water flow will move along the internal spiral blades 46, and the external water flow will continue to pass through the storage groove 44. Entering the collection cylinder 43, the internal water flow will move downward along the spiral blade 46, and finally be discharged from the bottom of the collection cylinder 43 to the top of the sludge after sedimentation. The cleaned impurities and dirt are collected and guided by the collection cylinder 43 to ensure that the cleaned dirt will not affect the sedimentation of the slurry above; and when the power motor 22 is reversed, the reciprocating up and down movement of the rotating cylinder 31 drives the fixing ring 41, the connecting rod 42 and the collection cylinder 43 to vibrate up and down. The vibration force of the reciprocating up and down collection cylinder 43 can clean the impurities and dirt that are not completely discharged from the spiral blade 46. ;
