Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a wastewater treatment device for meal replacement powder production. Background Art

[0002] Meal replacement powder is a convenient and fast nutritional supplement. A large amount of wastewater is generated during its production and processing. In order to avoid wastewater polluting the environment, it is usually treated multiple times before being discharged. The wastewater from meal replacement powder processing contains impurities such as suspended solids and grease. Therefore, it is often treated with a flotation machine, in which the wastewater is mixed with a flocculant to form flocs from the impurities. Subsequently, flotation treatment is performed using tiny bubbles attached to the flocs in the water to make the flocs float on the water surface. The flocs are then driven into a scum tank through a mechanical device to separate them from the water, completing the treatment of the wastewater. However, in this process, the action of driving the flocs away will cause some tiny bubbles to detach from the flocs, thereby causing some of the flocs to re-suspend in the water. The re-suspended flocs will sink to the bottom under the action of gravity, and the sank flocs will be discharged with the water flow, thereby affecting the treatment effect of the wastewater.

[0039] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0040] Research has found that in the process of using existing flotation machines for wastewater treatment, when driving out impurities in the floating flocs in the flotation machine, the action of driving out the flocs will cause tiny bubbles to separate from the flocs, causing the flocs to sink to the bottom under the action of gravity. The flocs that sink to the bottom will be discharged along with the water flow, resulting in poor wastewater treatment effect.

[0041] In view of the above problems, the present invention designs a wastewater treatment device which can avoid the discharge of flocculent impurities.

[0042] Example 1: A wastewater treatment device for meal replacement powder production, such as Figure 1-Figure 3 As shown, it includes a shell 1, a control terminal is installed on the front side of the shell 1, a first baffle 11, a second baffle 12 and a third baffle 13 are installed in the shell 1 from right to left, the shell 1, the first baffle 11 and the second baffle 12 form a serpentine chamber, the third baffle 13 is folded, the shell 1 is installed with an air flotation unit 121 electrically connected to the control terminal, the air flotation unit 121 is located between the first baffle 11 and the second baffle 12, a liquid guide cavity 14 is arranged on the left side of the shell 1, a liquid discharge pipe and a material discharge pipe are installed on the left side of the shell 1, the upper liquid discharge pipe of the shell 1 is connected with the liquid guide cavity 14, the liquid inlet of the liquid guide cavity 14 is located below the third baffle 13, and a filter is installed on the liquid inlet of the liquid guide cavity 14, the liquid inlet of the upper liquid discharge pipe of the shell 1 is lower than the upper surface of the second baffle 12, so that the flow path of the impurity-removed liquid is approximately U-shaped, so as to avoid the flocculants from being discharged from the liquid discharge port of the shell 1 during the sinking process, thereby ensuring the discharged The cleanliness of the outlet water is improved to improve the wastewater treatment effect. The shell 1 and the third baffle 13 cooperate to form a cavity. The discharge pipe on the shell 1 is connected to the upper cavity thereof. The discharge pipe on the shell 1 is used to discharge flocculent impurities. The front side wall of the shell 1 is fixedly connected to a driving motor 15 electrically connected to the control panel through a support. Two first rotating shafts 16 are rotatably arranged on the upper part of the shell 1. The output shaft of the driving motor 15 is fixedly connected to the front end of the first rotating shaft 16 on the right side. The two first rotating shafts 16 are respectively located on both sides of the second baffle 12. Two front-to-back symmetrical chains 17 are rotatably arranged between the two first rotating shafts 16 through a sprocket group. Two centrally symmetrical first fixed shells 18 are fixedly connected between the two chains 17. The first fixed shell 18 is provided with a first sliding plate 19. The first sliding plate 19 is rotated to scrape off flocculent impurities suspended on the water surface. A cleaning mechanism for cleaning the corresponding first sliding plates 19 is provided on the shell 1.

[0043] like Figure 3 and Figure 4As shown, the cleaning mechanism includes two front-to-back symmetrical support plates 2, both support plates 2 are fixed to the upper surface of the shell 1, the front support plate 2 is rotatably provided with a first rotating shaft 21, the front end of the first rotating shaft 21 is fixedly provided with a missing gear 22, the first rotating shaft 21 and the output shaft of the driving motor 15 are driven by a pulley and a belt, a second rotating shaft 23 is rotatably provided between the two support plates 2, the second rotating shaft 23 is located on the left side of the first rotating shaft 21, the front end of the second rotating shaft 23 is fixedly provided with a first spur gear 24 that is transmission-matched with the missing gear 22, a second fixed shell 25 is fixedly provided between the left parts of the two support plates 2, and the second fixed shell 25 A second sliding plate 26 is provided for internal sliding, and two tension springs symmetrically arranged front and back are installed between the left side of the second sliding plate 26 and the second fixed shell 25, and the right side of the second sliding plate 26 is connected to the second rotating shaft 23 by two pull ropes symmetrically arranged front and back. Nine uniformly distributed nozzles 27 are fixedly connected and connected to the left side of the second fixed shell 25, wherein the nine nozzles 27 are inclined outwardly from the middle to the front and rear sides, and the nozzles 27 are used to guide the gas to blow on the first sliding plate 19, so that the impurities on the first sliding plate 19 enter between the shell 1 and the third baffle 13, so as to prevent the floccules from falling to the bottom of the shell 1 again and causing the floccules to be unable to be discharged.

[0044] When the wastewater generated in the production process of the meal replacement powder is treated, the generated wastewater is added between the shell 1 and the first baffle 11, and at the same time, a flocculant is continuously and evenly added between the shell 1 and the first baffle 11. The flocculant is mixed with the wastewater to form flocs of oil and fat impurities in the wastewater. Then the water and the flocs flow into between the first baffle 11 and the second baffle 12. The subsequent control terminal starts the flotation unit 121 and the drive motor 15. The flotation unit 121 works to evenly spray tiny bubbles, which float and attach to the flocs, causing the flocs to quickly float to the liquid surface in the shell 1. The water after flocculation and impurity removal fills the left part of the shell 1 and contacts the third baffle 13. The impurity-removed water then enters the liquid guide cavity 14 and flows from the discharge pipe of the shell 1 to the next link.

[0045] In the above wastewater treatment process, the flocculants are always located on the upper surface of the water, and then the driving motor 15 works to drive the two chains 17 to rotate together through the two first rotating shafts 16 and the sprockets. The rotation of the two chains 17 drives the two first fixed shells 18 and the two first sliding plates 19 to move in a circular manner. The two first sliding plates 19 move alternately to push the flocculants and impurities on the upper surface between the second baffle 12 and the third baffle 13, and finally make the flocculants and impurities enter the cavity formed by the shell 1 and the third baffle 13, and then the flocculants and impurities enter the next processing link through the discharge pipe on the shell 1.

[0046] During the continuous movement of the two first sliding plates 19 to scrape and drive away the flocculent impurities on the water surface, the output shaft of the driving motor 15 drives the first rotating shaft 21 and the missing gear 22 to rotate through the pulley and the belt. The missing gear 22 first engages with the first spur gear 24, and then the missing gear 22 rotates through the first spur gear 24 to drive the second rotating shaft 23 to rotate and reel in the pull rope connected thereto. The reeling of the pull rope drives the second sliding plate 26 to move in the second fixed shell 25. The second sliding plate 26 moves and stretches the connected tension spring at the same time. When the first fixed shell 18 rotates close to the nozzle 27, the missing gear 22 disengages from the first spur gear 2 4, and subsequently, under the tension of the tension spring connected to the second sliding plate 26, the second sliding plate 26 moves in the opposite direction to push the gas in the second fixed shell 25, so that the gas is ejected from the nine nozzles 27 to blow the corresponding first fixed shell 18 and the adjacent first sliding plate 19, thereby reducing the residual impurities on the corresponding first fixed shell 18 and the corresponding first sliding plate 19, thereby preventing the flocculent impurities from falling to the bottom of the shell 1 again, and improving the discharge efficiency of the flocculent impurities. After that, when the missing gear 22 rotates again to mesh with the first spur gear 24, the above-mentioned cleaning operation of the corresponding first fixed shell 18 and the corresponding first sliding plate 19 is repeated.

[0047] In the above wastewater treatment process, the setting of the liquid-conducting chamber 14 makes the flow path of the liquid after impurity removal approximately U-shaped, thereby preventing the flocculants from being discharged from the discharge port of the shell 1 during the sedimentation process. At the same time, the filter screen at the liquid inlet on the liquid-conducting chamber 14 prevents the flocculated impurities in the interval between the second baffle 12 and the third baffle 13 from being suspended and sedimented to the bottom and entering the liquid-conducting chamber 14, thereby preventing the flocculants from being discharged from the discharge pipe of the shell 1, thereby improving the wastewater treatment efficiency of the device. After the treatment of this batch of wastewater is completed, the operator turns off the flotation unit 121 and the drive motor 15 through the control terminal, and then repeats the above operation when treating the remaining batches of wastewater.

[0048] Embodiment 2: Based on embodiment 1, Figure 5-Figure 7As shown, it also includes a limiting mechanism, which is arranged on the two first fixed shells 18. The limiting mechanism is used to limit the movement of the two first sliding plates 19. The opposite sides of the two first sliding plates 19 are provided with folding hooks. The first sliding plates 19 are slidably connected to the corresponding first fixed shells 18. Two front-to-back symmetrical tension springs are installed between the first sliding plates 19 and the corresponding first fixed shells 18. The limiting mechanism includes two centrally symmetrical groups of ratchet bars 3, each group of ratchet bars 3 includes two front-to-back symmetrical ones, and the two groups of ratchet bars 3 are respectively fixed to the corresponding first sliding plates 19, and the two ratchet bars in each group of ratchet bars 3 are respectively located at the front of the corresponding first sliding plates 19. The rear two parts, the front and rear parts of the first fixed shell 18 are both rotatably provided with a pawl 31, a torsion spring is installed between the pawl 31 and the adjacent first fixed shell 18, and the pawl 31 is limitedly cooperated with the adjacent ratchet 3 to limit the first sliding plate 19 from retracting into the adjacent first fixed shell 18, and the shell 1 is provided with a detection component for detecting the liquid level therein, and all the ratchet 3 are jointly provided with a reset component for resetting the two first sliding plates 19, and the first sliding plate 19 is adjusted to enable the first sliding plate 19 to accurately drive away the suspended impurities on the liquid surface, thereby improving the discharge efficiency of flocculant impurities, thereby improving the wastewater treatment efficiency of the device.

[0049] like Figure 3 , Figure 7 and Figure 8 As shown, the detection assembly includes two third fixed shells 4 that are symmetrical in front and back, and the two third fixed shells 4 are fixed to the inner wall of the shell 1. The third fixed shell 4 is located between the first baffle 11 and the second baffle 12. The two third fixed shells 4 are slidably provided with first sliding frames 41 on the opposite sides, and the right part of the first sliding frame 41 is slidably provided with two floating balls 42 that are symmetrical in left and right. An elastic member 5 is installed between the floating ball 42 and the adjacent first sliding frame 41. The elastic member 5 is set as a spring, and there is a damping between the first sliding frame 41 and the adjacent third fixed shell 4. The elastic member 5 is used to buffer the liquid surface fluctuation force acting on the adjacent first sliding frame 41. The left end of the first sliding frame 41 is fixed with a guide rod 43, which guides A telescopic rod 44 is rotatably provided on the right part of the rod 43, and the upper end of the telescopic rod 44 is rotatably connected to the shell 1. The first sliding plate 19 is fixedly connected to two front-to-back symmetrical fixed columns 45, and the fixed columns 45 are squeezed and matched with the corresponding guide rods 43 and the corresponding telescopic rods 44. A locking component for limiting all first sliding frames 41 is provided on the shell 1. The deformation of the elastic member 5 is used to buffer the fluctuation of the liquid level, so that the first sliding frame 41 remains relatively stable. The guide rod 43 squeezes the adjacent fixed columns 45 to make the first sliding plate 19 close to the liquid surface, so that the first sliding plate 19 can accurately drive away the flocculant impurities suspended on the liquid surface, thereby improving the separation and treatment effect of the flocculant and water.

[0050] like Figure 3 , Figure 8 and Fig. 9As shown, the locking component includes two groups of elastic telescopic push rods 6 that are symmetrical in front and back, and the two groups of elastic telescopic push rods 6 are fixed to the upper surface of the shell 1. Each group of elastic telescopic push rods 6 includes two symmetrical ones on the left and right. The telescopic ends of the two adjacent elastic telescopic push rods 6 on the left and right are commonly fixed to the limit rod 61. An airbag 62 is installed in the third fixed shell 4. The airbag 62 is connected to the chamber of the corresponding elastic telescopic push rod 6 through a pipeline. The left and right parts of the third fixed shell 4 are both slidably provided with a third sliding plate 63, and the third sliding plate 63 is adhered to the adjacent airbag 62. , and the third sliding plate 63 is squeezed and matched with the adjacent first sliding frame 41. The third sliding plate 63 moves to squeeze the adjacent first sliding frame 41 to limit its movement. Rectangular blocks 64 are fixed to the front and rear sides of the first fixed shell 18. The rectangular blocks 64 are squeezed and matched with the adjacent limiting rods 61. The first fixed shell 18 is swung toward the liquid surface so that the two rectangular blocks 64 thereon squeeze the two limiting rods 61 to move. Subsequently, the limiting of the first sliding frame 41 is completed by the connected parts to ensure that the first sliding plate 19 is adjusted to be close to the liquid surface.

[0051] like Figure 3 , Figure 6 and Figure 7 As shown, the reset assembly includes two groups of L-shaped rods 7 with central symmetry, each group of L-shaped rods 7 includes two symmetrical front and rear ones, and the four L-shaped rods 7 are respectively fixed to the corresponding ratchet pawls 31, and the front and rear parts of the first fixed shell 18 are both provided with sliding grooves for the sliding of adjacent L-shaped rods 7. The sliding grooves of the first fixed shell 18 are larger than the width of the L-shaped rod 7 in the vertical direction, so as to facilitate the automatic swinging of the L-shaped rod 7. The left part of the shell 1 is provided with two second sliding frames 71 symmetrical front and rear through two brackets for sliding. A tension spring is installed between the second sliding frame 71 and the corresponding bracket on the shell 1, and the second sliding frame 71 is squeezed and matched with the adjacent L-shaped rod 7. The second sliding frame 71 is used to squeeze the corresponding L-shaped rod 7 to trigger the corresponding ratchet 31 to swing and release the limit with the adjacent ratchet 3, so as to facilitate the resetting of the first sliding plate 19 and facilitate the targeted driving and separation of flocculants and impurities of different thicknesses on the water surface alternately by the two first sliding plates 19.

[0052] In the process of repeating the above-mentioned wastewater treatment operation, the buoyancy of the water between the first baffle plate 11 and the second baffle plate 12 lifts the four floating balls 42 to move, and the floating balls 42 drive the adjacent first sliding frame 41 and the adjacent guide rod 43 to move through the adjacent elastic member 5. The movement of the guide rod 43 simultaneously causes the adjacent telescopic rod 44 to appropriately contract. When the two chains 17 jointly drive one of the first fixed shells 18 and the adjacent first sliding plate 19 to move to the vicinity of the telescopic rod 44, the fixed column 45 on the first sliding plate 19 moves to the lower side of the adjacent telescopic rod 44. Surface, subsequently the first fixed shell 18 and the first sliding plate 19 continue to move, the telescopic rod 44 will squeeze the fixed column 45 on the first sliding plate 19, the first sliding plate 19 slides in the corresponding first fixed shell 18 and stretches the connected tension spring, wherein the first sliding plate 19 drives the adjacent ratchet 3 to move, the ratchet 3 moves and squeezes the adjacent ratchet 31 to swing, wherein the ratchet 31 is always pressed against the adjacent ratchet 3 by the torsion force of the torsion spring connected to the ratchet 31 here, limiting the first sliding plate 19 from retracting into the adjacent first fixed shell 18.

[0053] After the corresponding first sliding plate 19 swings into the guide rod 43, the first sliding plate 19 moves so that its folding hook is located below the liquid surface. Subsequently, the corresponding first fixed shell 18 and the first sliding plate 19 move past the limit rod 61. At this time, the two rectangular blocks 64 on the first fixed shell 18 squeeze the two limit rods 61 to move downward. The limit rod 61 moves downward and compresses the telescopic ends of the four elastic telescopic push rods 6 to move downward, wherein the inner chambers of the two elastic telescopic push rods 6 on the right side are injected into the two air bags 62 through the connected pipes. The two air bags 62 expand and squeeze the adjacent third sliding plate 63 to move close to the adjacent first sliding frame 41, completing the limiting of the first sliding frame 41. Subsequently, the first sliding plate 19 scrapes off the suspended impurities on the water surface to reduce the amount of water driven by the first sliding plate 19 to form a chamber between the shell 1 and the third baffle 13.

[0054] During the process of the first sliding plate 19 rotating to approach the corresponding telescopic rod 44, the elastic expansion and contraction change of the elastic member 5 connected to the float 42, accompanied by the friction between the third fixed shell 4 and the adjacent first sliding frame 41, prevents the fluctuation of the water surface from affecting the reciprocating movement of the first sliding frame 41, so that the corresponding guide rod 43 is always in a stable state, so that under the limiting effect of the guide rod 43, the folding hook of the first sliding plate 19 will be located below the liquid surface, thereby improving the effect of the first sliding plate 19 in cleaning suspended impurities on the water surface at a single time, reducing the amount of flocculent impurities sinking into the water again, and improving the efficiency of the device in driving away and separating impurities.

[0055] After the corresponding first fixed shell 18 and the corresponding first sliding plate 19 move through the two limit rods 61, the telescopic ends of the four elastic telescopic push rods 6 move in the opposite direction and reset, the four elastic telescopic push rods 6 reset and reset the connected third sliding plate 63 and the connected rectangular block 64, and the rectangular block 64 releases the limit on the adjacent first sliding frame 41, and then the first sliding plate 19 drives the adjacent second sliding frame 71 to move and fit the L-shaped rod 7 to move, and then the two second sliding frames 71 are limited and squeezed on the corresponding two L-shaped rods 7, and the two L-shaped rods 7 will drive the adjacent ratchet claws 31 to swing, and the ratchet claws 31 swing to release the limit on the adjacent ratchet strips 3, and then under the tension of the tension spring connected to the first sliding plate 19, the first sliding plate 19 is retracted into the adjacent first fixed shell 18, so that the first sliding plate 19 returns to its initial state, and then the two first sliding plates 19 alternately scrape and drive away the suspended impurities on the water surface, thereby reducing the waste of water after impurity removal and improving the wastewater treatment efficiency of the device.

[0056] Embodiment 3: Based on embodiment 2, Figure 5 , Fig.10 and Fig.11 As shown, it also includes a reciprocating mechanism, which is arranged on the two first fixed shells 18. The reciprocating mechanism is used to control the corresponding first sliding plates 19 to gradually move, so that the flocculent impurities are evenly attached to the left side of the corresponding first sliding plate 19. The reciprocating mechanism includes two centrally symmetrical second rotating shafts 8, and the two second rotating shafts 8 are respectively rotatably arranged at the rear of the adjacent first fixed shells 18. The second rotating shaft 8 is fixedly connected to the second spur gear 81, and a convex column is arranged at the eccentric position of the second spur gear 81. A conduit 82 is embedded in the rear of the first fixed shell 18, and a third sliding frame 83 is slidably arranged at the rear of the conduit 82. The third sliding frame 83 is provided with a horizontal slide groove, and the slide groove of the third sliding frame 83 is slidably connected with the convex column on the adjacent second spur gear 81. The front part of the third sliding frame 83 is provided with four through holes distributed equidistantly in the circumferential direction. The four through holes of the third sliding frame 83 One-way valves are installed in the through hole and in the conduit 82. The one-way valve on the third sliding frame 83 is used for external gas to enter the adjacent conduit 82. The front part of the conduit 82 is slidably provided with a connecting rod 84 fixedly connected to the adjacent first sliding plate 19. The one-way valve in the conduit 82 is used for gas to flow therein close to the corresponding connecting rod 84. A through hole is provided at the corner of the conduit 82. The support plate 2 on the rear side is fixedly connected with a rack 85 that is transmission-matched with the corresponding second spur gear 81. The two rectangular blocks 64 on the rear side are jointly provided with a blocking component for blocking the through holes on the two conduits 82. Gas is injected into the corresponding conduit 82 through the reciprocating movement of the third sliding frame 83, which facilitates the adjacent connecting rod 84 to drive the corresponding first sliding plate 19 to move, so that the flocculant impurities suspended on the water surface always adhere to the left side of the corresponding first sliding plate 19, thereby improving the separation and expulsion effect of the flocculant impurities.

[0057] like Fig.10 and Fig.11 As shown, the blocking component includes two sliding columns 9 that are centrally symmetrical. The two sliding columns 9 are respectively slidably arranged in the two rectangular blocks 64 on the rear side. A spring is installed between the sliding column 9 and the adjacent rectangular block 64. The opposite sides of the two sliding columns 9 are fixedly connected with a fixing frame 91. The conduit 82 is fixedly connected with a fixing pipe 92. The fixing pipe 92 is communicated with the through hole on the adjacent conduit 82. The fixing frame 91 penetrates the adjacent fixing pipe 92 and is slidably connected thereto. The fixing frame 91 is used to block the adjacent fixing pipe 92. An inclined surface is provided on the side of the sliding column 9 away from the adjacent fixing frame 91. An inclined surface is provided on the right part of the limiting rod 61. The inclined surface on the sliding column 9 is squeezed and matched with the inclined surface on the adjacent limiting rod 61. The fixing frame 91 is used to block and open the adjacent fixed pipe 92, and the first sliding plate 19 close to the water surface is controlled to move and reset adaptively, thereby improving the separation effect of flocculant impurities in the water, thereby improving the wastewater treatment efficiency of the device.

[0058] In the initial state, due to the elastic force of the spring connected to the sliding column 9, the fixing frame 91 does not block the adjacent fixed tube 92 in the initial state. Subsequently, when the fixing column 45 is squeezed by the corresponding telescopic rod 44, the first sliding plate 19 extends from the adjacent first fixed shell 18. The first sliding plate 19 simultaneously drives the adjacent connecting rod 84 to move in the adjacent conduit 82. Subsequently, the first sliding plate 19 continues to drive the connected parts to repeat the above movement.

[0059] In the process of the rear rectangular block 64 moving and squeezing the rear limiting rod 61, the rear limiting rod 61 simultaneously squeezes the corresponding sliding column 9 and the corresponding fixing frame 91 to move, the sliding column 9 moves to compress the connected spring, and the fixing frame 91 moves to block the adjacent fixing tube 92, and then the first sliding plate 19 passes through the limiting rod 61, and the corresponding second spur gear 81 will mesh with the adjacent rack 85, and then the first sliding plate 19 is moving, and the second spur gear 81 thereon continues to rotate, and the second spur gear 81 rotates and squeezes the slide groove of the adjacent third sliding frame 83 through the convex column thereon, so that the third sliding frame 83 reciprocates in the conduit 82, at this time, the one-way valve in the conduit 82 and the third sliding frame 83 are affected. 3, the outside gas gradually contacts the adjacent connecting rod 84 through the one-way valve on the third sliding frame 83 and the one-way valve in the conduit 82. As the gas gradually enters the conduit 82, the gas pressure gradually squeezes the connecting rod 84 to move, and the connecting rod 84 drives the adjacent first sliding plate 19 to move. The depth of the first sliding plate 19 inserted into the water gradually increases, and the suspended impurities on the water surface accumulate on the left side of the first sliding plate 19. Subsequently, the first sliding plate 19 moves downward to make the suspended impurities evenly accumulate on its left side, while avoiding too much water in the suspended impurities, further improving the separation effect of the device on the suspended impurities on the water surface, thereby improving the wastewater treatment efficiency of the device.

[0060] After the first sliding plate 19 passes through the limiting rod 61, the limiting rod 61 releases the squeezing of the corresponding sliding column 9. Under the elastic force of the spring connected to the sliding column 9, the sliding column 9 drives the adjacent fixing frame 91 to move in the opposite direction and reset. The fixing frame 91 releases the blockage of the adjacent fixed tube 92. Then the above operation is repeated. The second sliding frame 71 limits and squeezes the corresponding L-shaped rod 7, so that the first sliding plate 19 is retracted into the corresponding first fixed shell 18. Subsequently, the above cycle of driving away suspended impurities is repeated.
