[0002] The wastewater generated during the processing of dried tofu mainly comes from the production links such as soybean soaking, grinding, boiling, pressing, and coagulation.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Example 1, reference Figure 1-2 A wastewater treatment device for dried tofu processing includes a wastewater treatment box 1 and a support base 2 installed at the bottom thereof, an electric telescopic rod 17 is installed at the bottom of the wastewater treatment box 1, and a regulating component is installed between the top of the electric telescopic rod 17 and the side wall of the wastewater treatment box 1.

[0041] Reference Figure 6A reagent delivery assembly is also provided inside the wastewater treatment box 1, and the reagent delivery assembly includes a material delivery assembly, an outer tube 4, an inner tube 25 and a leakage hole 27. The outer tube 4 is fixedly installed on the material delivery assembly, the inner tube 25 is located on the inner side of the outer tube 4, and the inner wall of the outer tube 4 and the outer surface of the inner tube 25 are in contact with each other. A plurality of leakage holes 27 are distributed in a circular array on the inner tube 25 and the outer tube 4, wherein one end of the outer tube 4 extends to the outside of the material delivery assembly, and one end of the inner tube 25 is connected to the liquid supply device through a pipeline.

[0042] When the wastewater inside the wastewater treatment box 1 is treated, along with the reciprocating up and down motion of the electric telescopic rod 17, the outer tube 4 is driven to rotate by the toggle assembly. When the outer tube 4 rotates, one end of the inner tube 25 is fixed on the wastewater treatment box 1, and the inner tube 25 does not rotate during the whole process. The rotation of the outer tube 4 drives the position of the leakage hole 27 outside it to rotate. When the leakage hole 27 outside the outer tube 4 coincides with the leakage hole 27 outside the inner tube 25, the reagent inside the inner tube 25 will pass through the leakage hole 27 into the interior of the wastewater treatment box 1. One end of the inner tube 25 is connected to the liquid supply equipment to ensure that the reagent inside the inner tube 25 is sufficient. The intermittent addition of reagent is because the baffle 14 moving up and down can evenly mix the reagent in the wastewater in the shortest time.

[0043] Reagents may be selected from coagulants, pH adjusters, disinfectants or decolorizers. In wastewater treatment, coagulants are often used to help suspended matter and colloidal substances condense into larger particles for easy precipitation or filtration removal. The pH value of wastewater is crucial to subsequent treatment steps. If the pH value of the wastewater is not within the appropriate range, acid or alkali may need to be added to adjust the pH value to optimize the treatment effect. In the final stage of wastewater treatment, disinfection is usually required to kill harmful microorganisms in the wastewater. The pigment composition in soy product wastewater is complex and has poor biodegradability, so a decolorizer is needed to remove the pigment.

[0044] Example 2, reference Figure 8 The difference between this embodiment and embodiment 1 is that the regulating component includes a bean curd collecting component and a bean curd placing component; the bean curd collecting component includes a base 18, a rotating drum 24, an arc-shaped groove 19, a baffle 14, a drying rod 13 and a bean dregs processing component; the base 18 is detachably connected to the top of the electric telescopic rod 17 through a clamp, the two baffles 14 are tilted downward and symmetrically arranged on the upper part of the base 18, the arc-shaped groove 19 is opened at the bottom connection position of the two baffles 14, the drying rod 13 is located on the inner side of the arc-shaped groove 19, and the two ends of the drying rod 13 extend to the outside of the arc-shaped groove 19, and a rotating drum 24 is rotatably arranged at the two ends of the drying rod 13, and the bean curd placing component includes a limit rod 20, a placing plate 21, a partition component 22 and a partition 28.

[0045] The placement plate 21 is hinged on the inner side of the wastewater treatment box 1 in an inclined state, the limit rod 20 is fixed at the bottom of the wastewater treatment box 1, and the limit rod 20 is in contact with the bottom of the placement plate 21, and the partition plate 28 is vertically installed at the end position of the placement plate 21. When the drying rod 13 is located at the upper end of the placement plate 21, the drying rod 13 will fold the bean curd 23 in half and prop it up, and multiple groups of partition components 22 are evenly installed on the upper end of the placement plate 21.

[0046] When the wastewater treatment starts, the wastewater generated during the soybean processing is injected into the wastewater treatment tank 1. In the generated wastewater, soybean skin, as a suspended matter, will have a certain impact on the wastewater treatment process. The soybean skin contains plant cell wall components and is not easy to decompose. If it is not properly pretreated, it may cause blockage problems in the wastewater treatment system, affecting the treatment efficiency and the normal operation of the subsequent biological treatment process.

[0047] For this reason, in the process of wastewater treatment, the bean curd formed on the surface needs to be treated first. After a period of standing, the bean curd will appear on the surface of the wastewater. At this time, the power switch of the electric telescopic rod 17 is started to control the length of the electric telescopic rod 17 to increase, and the baffle plate 14 at the upper end is lifted upward. The angle between the two baffle plates 14 is an obtuse angle. The drying rod 13 on the inner side of the arc groove 19 at the connection between the two baffle plates 14 rises together. When the upper end of the drying rod 13 rises, it will contact the bean curd formed on the surface. The drying rod 13 scoops up the bean curd and contacts the end position of the placement plate 21 above. Since the placement plate 21 is connected in a hinged form, the placement plate 21 will be driven to rise as the drying rod 13 continues to rise. 1 rotates upward until a certain height is reached, the placement plate 21 is separated from the drying rod 13, and the placement plate 21 is reset. At this time, the height of the electric telescopic rod 17 is lowered, and the rotating drums 24 at both ends of the drying rod 13 will fall on the placement plates 21 on both sides. Since the placement plates 21 are arranged at an angle, under the action of gravity, the rotating drum 24 rotates on the placement plate 21 to the other end of the placement plate 21, and the first drying rod 13 contacts the partition plate 28 to prevent the drying rod 13 from continuing to roll. In this way, the bean skin formed on the surface is transferred to the placement plate 21 through the drying rod 13. The bean skin recovery is an important step in wastewater treatment. At the same time, the collected bean skin can also be used as a raw material for processing animal feed and fertilizer.

[0048] Example 3, reference Figure 3-4 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the bean dregs processing component includes a collecting bin 16 and a slot hole 15, a plurality of slot holes 15 are arranged on the baffle 14 along the short side direction, and the collecting bin 16 is located at the lower end of the baffle 14 at the lower end of the slot hole 15.

[0049] The wastewater also contains some bean dregs from the processing of dried tofu, which can also be used as fertilizer or animal feed. The bean dregs are located in the wastewater below the surface of the bean skins and should be treated during the wastewater treatment process.

[0050] To this end, as the baffle 14 moves back and forth up and down on the inner side of the wastewater treatment box 1, the bean dregs will gather on the two baffles 14 during the rising process of the baffle 14. The baffle 14 is arranged at an angle. When the bean dregs are located on the baffle 14, under the action of the water flow, the bean dregs will pass through the slots 15 on the baffle 14 and enter the collecting bin 16 for collection. Secondly, the base 18 and the collecting bin 16 are both detachably connected, for example, connected in a snap-fit ​​manner, which also facilitates the collection of the bean dregs collected in the collecting bin 16 at a later time.

[0051] Example 4, reference Figure 8-9 The difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that the partition assembly 22 includes a pressing plate 221, an elastic band 222, a rotating shaft 223, a round rod 224 and a square groove 225; the square groove 225 is opened at the upper end of the placement plate 21, the pressing plate 221 is swingably set in the square groove 225 through the rotating shaft 223, the round rod 224 is installed at the inner bottom of the round rod 224, and the elastic band 222 is symmetrically installed on the pressing plate 221 and the round rod 224. In the initial state, the pressing plate 221 is in a horizontal state.

[0052] Since the bean curd skin has a certain stickiness when wet, if the multiple drying rods 13 transferred to the upper end of the placement plate 21 are attached to each other, the bean curd skins will all stick together, which will cause certain difficulties in later recycling.

[0053] To this end, a plurality of partition components 22 are evenly arranged at the upper end of the placement plate 21, and the partition components 22 include a pressing plate 221, an elastic band 222, a rotating shaft 223, a round rod 224 and a square groove 225. In the initial position, the pressing plate 221 is in a horizontal state on the inner side of the square groove 225. Since the placement plate 21 is inclined, the end of the pressing plate 221 will be tilted out of the outer side of the square groove 225. When the rotating drum 24 on the outer side of the drying rod 13 contacts the tilted pressing plate 221, due to the weight of the drying rod 13 and the bean skin, the part originally located on the inner side of the square groove 225 will be tilted upward. In this way, the next drying rod 13 entering the upper end of the placement plate 21 will contact with one end of the previously tilted pressing plate 221, thereby limiting the position of the next drying rod 13. At this time, the distance between two adjacent drying rods 13 is increased, so that the bean skin on each drying rod 13 can be effectively separated and will not stick together.

[0054] Example 5, reference Figure 5The difference between this embodiment and Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4 is that the material delivery assembly includes a sleeve 5, a discharge port 6, a discharge port 11, a rotating column 12 and a accommodating chamber 26; the sleeve 5 is horizontally fixedly installed on the inner side of the wastewater treatment box 1, the rotating column 12 is rotatably arranged on the inner side of the sleeve 5, the discharge port 6 and the discharge port 11 are respectively opened on the upper part and the side of the sleeve 5, the accommodating chamber 26 is distributed in a circular array on the inner side of the rotating column 12, and the drying rod 13 enters the accommodating chamber 26 inside the sleeve 5 from the discharge port 6.

[0055] refer to Figure 7 The outer tube 4 extends along the axis direction of the rotating column 12 and to the outside of the sleeve 5. A toggle assembly is arranged between the end position of the outer tube 4 and the base 18. The toggle assembly includes a driving assembly, a support frame 7, a connecting plate 8 and a limiter 9; the support frame 7 is installed on one side of the base 18, the connecting plate 8 is obliquely installed on the support frame 7, and the limiter 9 is installed on the upper part of the connecting plate 8.

[0056] The driving assembly includes a ratchet 3 and a pawl 10. The pawl 10 is hinged on the connecting plate 8. One end of the limiter 9 is attached to the outside of the pawl 10. The ratchet 3 is installed at the end of the outer tube 4. When the pawl 10 moves toward the upper end, the pawl 10 passes through the edge of the ratchet 3 and does not drive the ratchet 3 to rotate. When the pawl 10 moves to the lower end, the pawl 10 drives the ratchet 3 to rotate. When the baffle 14 moves up and down, a spacing is set between the baffle 14 and the sleeve 5.

[0057] Since bean curd is usually formed at intervals, multiple different drying rods 13 are needed to support the bean curd formed in different time periods, and when the previous drying rod 13 leaves the arc groove 19, the next drying rod 13 must be re-filled into the arc groove 19 as soon as possible.

[0058] To this end, a sleeve 5 is arranged at a position where one of the baffles 14 descends, and a rotating column 12 is arranged inside the sleeve 5. A plurality of accommodating chambers 26 are arranged in a circular array at the circumferential position of the rotating column 12. These accommodating chambers 26 are used to place the drying rods 13. Specifically, the drying rods 13 are placed from the discharge port 6 at the upper end of the sleeve 5, and the rotating column 12 is rotated so that the drying rods enter different accommodating chambers 26. At this time, when the baffle 14 descends, the pawl 10 installed at the end of the connecting plate 8 drives the ratchet 3 at the end of the outer tube 4 to rotate clockwise, and the internal rotating column 12 is driven to rotate during the rotation. It rotates, thereby driving the position of the accommodating chamber 26 and the drying rod 13 therein, ensuring that each time the accommodating chamber 26 is driven to rotate, one drying rod 13 can slide out from the discharge port 11 and pass through the baffle 14 and finally enter the inner side of the arc groove 19, so as to complete the support of the next bean skin. It should be specifically explained that when the pawl 10 moves to the upper end, the pawl 10 passes through the edge of the ratchet 3 and will not drive the ratchet 3 to rotate. When the pawl 10 moves to the lower end, after the angle of the pawl 10 is adjusted, it is resisted by the limiting member 9 at the rear and cannot change the angle any more, thereby realizing that the pawl 10 drives the ratchet 3 to rotate.

[0059] The working principle of the device is:

[0060] When the wastewater inside the wastewater treatment box 1 is treated, along with the reciprocating up and down motion of the electric telescopic rod 17, the outer tube 4 is driven to rotate by the toggle assembly. When the outer tube 4 rotates, one end of the inner tube 25 is fixed on the wastewater treatment box 1, and the inner tube 25 does not rotate during the whole process. The rotation of the outer tube 4 drives the position of the leakage hole 27 outside it to rotate. When the leakage hole 27 outside the outer tube 4 coincides with the leakage hole 27 outside the inner tube 25, the reagent inside the inner tube 25 will pass through the leakage hole 27 into the interior of the wastewater treatment box 1. One end of the inner tube 25 is connected to the liquid supply equipment to ensure that the reagent inside the inner tube 25 is sufficient. The intermittent addition of reagent is because the baffle 14 moving up and down can evenly mix the reagent in the wastewater in the shortest time.

[0061] Reagents may be selected from coagulants, pH adjusters, disinfectants or decolorizers. In wastewater treatment, coagulants are often used to help suspended matter and colloidal substances condense into larger particles for easy precipitation or filtration removal; the pH value of wastewater is crucial to subsequent treatment steps. If the pH value of the wastewater is not within the appropriate range, acid or alkali needs to be added to adjust the pH value to optimize the treatment effect; in the final stage of wastewater treatment, disinfection is usually required to kill harmful microorganisms in the wastewater; the pigment composition in soy product wastewater is complex and has poor biodegradability, so a decolorizer is needed to remove the pigment.

[0062] When the wastewater treatment starts, the wastewater generated during the soybean processing is injected into the wastewater treatment tank 1. In the generated wastewater, soybean skin, as a suspended matter, will have a certain impact on the wastewater treatment process. The soybean skin contains plant cell wall components and is not easy to decompose. If it is not properly pretreated, it may cause blockage problems in the wastewater treatment system, affecting the treatment efficiency and the normal operation of the subsequent biological treatment process.

[0063] For this reason, in the process of wastewater treatment, the bean curd formed on the surface needs to be treated first. After a period of standing, the bean curd will appear on the surface of the wastewater. At this time, the power switch of the electric telescopic rod 17 is started to control the length of the electric telescopic rod 17 to increase, and the baffle plate 14 at the upper end is lifted upward. The angle between the two baffle plates 14 is an obtuse angle. The drying rod 13 on the inner side of the arc groove 19 at the connection between the two baffle plates 14 rises together. When the upper end of the drying rod 13 rises, it will contact the bean curd formed on the surface. The drying rod 13 scoops up the bean curd and contacts the end position of the placement plate 21 above. Since the placement plate 21 is connected in a hinged form, the placement plate 21 will be driven to rise as the drying rod 13 continues to rise. 1 rotates upward until a certain height is reached, the placement plate 21 is separated from the drying rod 13, and the placement plate 21 is reset. At this time, the height of the electric telescopic rod 17 is lowered, and the rotating drums 24 at both ends of the drying rod 13 will fall on the placement plates 21 on both sides. Since the placement plates 21 are arranged at an angle, under the action of gravity, the rotating drum 24 rotates on the placement plate 21 to the other end of the placement plate 21, and the first drying rod 13 contacts the partition plate 28 to prevent the drying rod 13 from continuing to roll. In this way, the bean skin formed on the surface is transferred to the placement plate 21 through the drying rod 13. The bean skin recovery is an important step in wastewater treatment. At the same time, the collected bean skin can also be used as a raw material for processing animal feed and fertilizer.

[0064] Since the bean curd skin has a certain stickiness when wet, if the multiple drying rods 13 transferred to the upper end of the placement plate 21 are attached to each other, the bean curd skins will all stick together, which will cause certain difficulties in later recycling.

[0065] To this end, a plurality of partition components 22 are evenly arranged at the upper end of the placement plate 21, and the partition components 22 include a pressing plate 221, an elastic band 222, a rotating shaft 223, a round rod 224 and a square groove 225. In the initial position, the pressing plate 221 is in a horizontal state on the inner side of the square groove 225. Since the placement plate 21 is inclined, the end of the pressing plate 221 will be tilted out of the outer side of the square groove 225. When the rotating drum 24 on the outer side of the drying rod 13 contacts the tilted pressing plate 221, due to the weight of the drying rod 13 and the bean skin, the part originally located on the inner side of the square groove 225 will be tilted upward. In this way, the next drying rod 13 entering the upper end of the placement plate 21 will contact with one end of the previously tilted pressing plate 221, thereby limiting the position of the next drying rod 13. At this time, the distance between two adjacent drying rods 13 is increased, so that the bean skin on each drying rod 13 can be effectively separated and will not stick together.

[0066] The wastewater also contains some bean dregs from the processing of dried tofu, which can also be used as fertilizer or animal feed. The bean dregs are located in the wastewater below the surface of the bean skins and should be treated during the wastewater treatment process.

[0067] To this end, as the baffle 14 moves back and forth up and down on the inner side of the wastewater treatment box 1, the bean dregs will gather on the two baffles 14 during the rising process of the baffle 14. The baffle 14 is arranged at an angle. When the bean dregs are located on the baffle 14, under the action of the water flow, the bean dregs will pass through the slots 15 on the baffle 14 and enter the collecting bin 16 for collection. Secondly, the base 18 and the collecting bin 16 are both detachably connected, for example, connected in a snap-fit ​​manner, which also facilitates the collection of the bean dregs collected in the collecting bin 16 at a later time.

[0068] Since bean curd is usually formed at intervals, multiple different drying rods 13 are needed to support the bean curd formed in different time periods, and when the previous drying rod 13 leaves the arc groove 19, the next drying rod 13 must be re-filled into the arc groove 19 as soon as possible.

[0069] To this end, a sleeve 5 is arranged at a position where one of the baffles 14 descends, and a rotating column 12 is arranged inside the sleeve 5. A plurality of accommodating chambers 26 are arranged in a circular array at the circumferential position of the rotating column 12. These accommodating chambers 26 are used to place the drying rods 13. Specifically, the drying rods 13 are placed from the discharge port 6 at the upper end of the sleeve 5, and the rotating column 12 is rotated so that the drying rods enter different accommodating chambers 26. At this time, when the baffle 14 descends, the pawl 10 installed at the end of the connecting plate 8 drives the ratchet 3 at the end of the outer tube 4 to rotate clockwise, and the internal rotating column 12 is driven to rotate during the rotation. It rotates, thereby driving the position of the accommodating chamber 26 and the drying rod 13 therein, ensuring that each time the accommodating chamber 26 is driven to rotate, one drying rod 13 can slide out from the discharge port 11 and pass through the baffle 14 and finally enter the inner side of the arc groove 19, so as to complete the support of the next bean skin. It should be specifically explained that when the pawl 10 moves to the upper end, the pawl 10 passes through the edge of the ratchet 3 and will not drive the ratchet 3 to rotate. When the pawl 10 moves to the lower end, after the angle of the pawl 10 is adjusted, it is resisted by the limiting member 9 at the rear and cannot change the angle any more, thereby realizing that the pawl 10 drives the ratchet 3 to rotate.
