Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, and in particular to a high-efficiency wastewater treatment device for mechanical sand making. Background Art

[0002] Mechanical sand making refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. With the continuous increasing demand for infrastructure construction, the output of machine-made sand has increased year by year, but the contradiction between the large-scale generation of machine-made sand wastewater and environmental protection and water conservancy and flood control is also becoming increasingly prominent.

[0003] There are many impurities in the wastewater from mechanical sand making. For the treatment of wastewater from mechanical sand making, flocculation is generally carried out first. Flocculation refers to the aggregation and enlargement of suspended particles in water or liquid, or the formation of flocs, thereby accelerating the aggregation of particles and achieving the purpose of solid-liquid separation. The flocculation step can effectively remove suspended impurities in the wastewater.

[0004] However, the existing mechanical sand making wastewater treatment devices on the market exist in actual work. Traditionally, the flocculant and wastewater are mixed in a rotating mixing manner. This mixing method is very simple. Secondly, there are many types of impurities in the wastewater, which may lead to insufficient mixing. Secondly, it is not convenient to continuously add the required flocculant in a quantitative manner, which may cause insufficient effect on the flocculant and wastewater. At the same time, the suspended impurities after flocculation will accumulate in the flocculation box, which may easily cause blockage and affect the overall flocculation efficiency.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The invention provides a high-efficiency wastewater treatment device for mechanical sand making.

[0057] First embodiment:

[0058] See also Figures 1 to 7, a high-efficiency wastewater treatment device for mechanical sand making, comprising a bottom plate 1, a limiting sleeve 11, a flocculation mechanism 3, a driving mechanism 4 and a cleaning mechanism 5;

[0059] Four vertical plates 2 are fixedly arranged on the upper surface of the bottom plate 1, and the flocculation mechanism 3 includes a flocculation box 31. Two limit rods 35 are fixedly arranged above the four vertical plates 2. A load-bearing plate 32 is fixedly connected to the inside of the flocculation box 31. A sealing door 33 is installed on the side wall of the flocculation box 31 and in the same horizontal direction as the load-bearing plate 32. Sliders 34 are fixedly arranged on the front and back sides of the flocculation box 31. Four limit springs 36 are sleeved on the outer walls of the two limit rods 35. Limit plates 37 are installed on the sides of two of the vertical plates 2 by bolts. A slide rod 38 is fixedly arranged in the middle of the outer wall of the limit plate 37. One end of the slide bar 38 extends to the inside of the flocculation box 31, and a stirring rod 39 is fixedly arranged in an equidistant ring on the outer wall of the slide bar 38 and around the axis of the slide bar 38. A sleeve 310 is installed inside the limit plate 37 and above the slide bar 38 through bolts, and a push rod 311 is slidably connected inside the sleeve 310. A first one-way valve 312 and a second one-way valve 313 are respectively installed on the inner wall of the sleeve 310 and at one end of the push rod 311. The liquid inlet end of the first one-way valve 312 is installed with an inlet pipe 315, and the liquid outlet end of the second one-way valve 313 is installed with a feed pipe 314;

[0060] The upper surface of the flocculation box 31 is connected to and fixed with a hopper 12;

[0061] See also Figure 4 and Figure 5 : The driving motor 42 drives the key rod 45 to rotate. When the key rod 45 rotates, it will synchronously drive the half gear 46 to rotate. If the half gear 46 rotates counterclockwise, the tooth surface of the half gear 46 will first engage with the second rack 49 to control the reciprocating ring 43 to pull the flocculation box 31 to move to the right. As the tooth surface of the half gear 46 rotates to the first rack 44, it will engage with the reciprocating ring 43 to drive the flocculation box 31 to move from the right to the left. In this way, the continuous rotation of the half gear 46 will realize the left and right reciprocating motion of the flocculation box 31.

[0062] The driving mechanism 4 comprises a mounting plate 41 fixedly mounted on the outer wall of the vertical plate 2, a driving motor 42 is mounted on the lower surface of the mounting plate 41 by bolts, a key rod 45 is connected to the keyway of the output shaft of the driving motor 42, a half gear 46 and a full gear 47 are sleeved on the outer wall of the key rod 45, a knob 48 is threadedly connected at the transition between the half gear 46 and the full gear 47, a reciprocating ring 43 is arranged on the upper surface of the mounting plate 41 and outside the key rod 45, a first rack 44 and a second rack 49 are respectively fixed on the inner wall of the reciprocating ring 43;

[0063] See also Figure 6:When the flocculation box 31 moves from left to right during the translational motion, the push rod 311 will be driven to move from left to right, so that the push rod 311 can slide inside the sleeve 310 to extract the liquid flocculant through the inlet pipe 315 and the first one-way valve 312 to enter the sleeve 310, and then when it moves from right to left, the push rod 311 will be pushed to move from right to left to squeeze the extracted liquid flocculant through the second one-way valve 313 and squeezed into the feed pipe 314, and then the liquid flocculant will enter the flocculation box 31 through the feed pipe 314 to mix with the wastewater to achieve flocculation;

[0064] When the flocculation box 31 is in the process of reciprocating movement, since the slide bar 38 is stationary, the slide bar 38 and the stirring rod 39 can reciprocate inside the flocculation box 31 by relying on the movement of the flocculation box 31.

[0065] Preferably, the stirring rod 39 is preferably made of rubber material.

[0066] See also Figure 5 : If the tooth surface of the half gear 46 is meshed with the second rack 49, the toothless surface is opposite to the first rack 44. When the tooth surface of the half gear 46 is meshed with the first rack 44, the toothless surface is opposite to the second rack 49. Therefore, the half gear 46 will not interfere with the reciprocating ring 43 during continuous rotation.

[0067] The cleaning mechanism 5 includes a movable rack 51 slidably connected to the inside of the limiting sleeve 11 , a contact plate 52 is fixedly disposed on the outer wall of one end of the movable rack 51 , and a scraper 53 is disposed inside the flocculation box 31 and on the upper surface of the bearing plate 32 .

[0068] See also Figure 4 and Figure 5 : Slide the half gear 46 and the full gear 47 along the vertical direction of the key rod 45, so that the half gear 46 will be separated from the reciprocating ring 43, and the full gear 47 will move upward and engage with the moving rack 51. The user starts the drive motor 42 to control the key rod 45 to control the full gear 47 to rotate counterclockwise and engage with the moving rack 51 to push the scraper 53 on the supporting plate 32 from right to left, so that the scraper 53 can push all the flocculated impurities on the supporting plate 32 to the direction of the sealing door 33.

[0069] The two sliders 34 are slidably connected to the two limit rods 35 , and the tooth surface of the half gear 46 is meshed with the second rack 49 .

[0070] The reciprocating ring 43 is fixedly connected to the flocculation box 31, the lower surface of the reciprocating ring 43 and the upper surface of the mounting plate 41 are in contact with each other, the moving rack 51 is fixedly connected to the scraper 53, and the full gear 47 and the moving rack 51 are adapted to each other;

[0071] The push rod 311 is fixedly connected to the upper surface of the flocculation box 31 , and the outlet end of the feed pipe 314 is connected and installed with the flocculation box 31 .

[0072] from Figure 3 It can be seen from the figure that the reciprocating motion of the flocculation box 31 is along the horizontal direction of the limiting rod 35. In this way, the movement of the flocculation box 31 is supported and limited by the limiting spring 36, which can ensure that the movement of the flocculation box 31 is more stable and smooth.

[0073] Understandable: From Figure 6 It can be seen that the first one-way valve 312 moves from the outside to the inside of the casing 310 in a one-way manner, and the second one-way valve 313 moves from the inside to the outside of the casing 310 in a one-way manner, so that when the flocculant is extracted, the second one-way valve 313 is closed, and when the flocculant is pushed out, the first one-way valve 312 is closed;

[0074] Secondly, the inlet pipe 315 can be installed with an external liquid flocculant storage box to ensure that the flocculant can be transported. The sliding connection between the push rod 311 and the sleeve 310 can be connected by rubber, and its principle is similar to that of a syringe.

[0075] This embodiment: Compared with the traditional design, this case adopts a reciprocating flocculation box 31, and the left and right reciprocating flocculation box 31 can cooperate with the static stirring rod 39, so that the wastewater entering the hopper 12 and the flocculant entering the feed pipe 314 can be fully mixed and stirred, ensuring that the flocculant is mixed evenly. Compared with the traditional mixing method, this case is further provided with a moving stirring rod 39 on the basis of the reciprocating motion. At the same time, the flocculant can be extracted and pushed out in a linkage manner during the movement of the flocculation box 31, so as to achieve an integrated linkage operation of mixing and feeding. Secondly, the amount of flocculant extracted is also quantitative, so as to achieve accurate addition of flocculant, ensuring that the wastewater and flocculant can fully affect flocculation, and after the flocculation is completed, there are flocculated impurities inside the flocculation box 31, and the movement of the scraper 53 can remove the flocculated impurities on the supporting plate 32, so as to avoid the supporting plate 32 being blocked by impurities, thereby improving the working efficiency of water treatment.

[0076] Second embodiment:

[0077] See also Figure 1 , Figure 8 and Fig.11 The bottom end of the flocculation box 31 is connected to a flexible tube 16, and the bottom end of the flexible tube 16 is connected to a treatment box 13;

[0078] A vibration mechanism 6 and a backwash mechanism 7 are respectively installed inside the processing box 13, the vibration mechanism 6 includes a vibration motor 61 installed on the upper surface of the processing box 13, the output shaft keyway of the vibration motor 61 is connected to a universal joint 62, the inner top and inner bottom of the processing box 13 are respectively fixed with a first limit frame 63 and a second limit frame 64, the inner walls of the first limit frame 63 and the second limit frame 64 are respectively fixed with two first positioning springs 68 and a second positioning spring 610, a first positioning block 69 is fixed on the opposite side of the two first positioning springs 68, a second positioning block 611 is fixed on the opposite side of the two second positioning springs 610, a screen barrel 65 is fixed on the upper surface of the second positioning block 611, a mounting cylinder 66 is fixed at the inner bottom axis of the screen barrel 65, and an eccentric roller 67 is connected to the inner keyway of the bottom end axis of the universal joint 62 that passes through the first positioning block 69;

[0079] Preferably, the screen barrel 65 may preferably have a tapered structure that is wider at the top and narrower at the bottom.

[0080] See also Figure 8 and Fig. 9 : The vibration motor 61 drives the universal joint 62 to rotate, and the universal joint 62 transmits the rotational force to the eccentric roller 67 inside the mounting barrel 66. When the eccentric roller 67 rotates, due to the different weights on both sides of the eccentric roller 67, a vibration force will be generated under high-speed rotation. The vibration force will affect the mounting barrel 66 to control the entire screen barrel 65 to vibrate slightly, so that the wastewater passing through the screen barrel 65 will be vibrated and screened, and finer impurities (such as sludge) will remain in the screen barrel 65, and the separated wastewater will continue to flow downward from the outside of the screen barrel 65.

[0081] It is understandable that since the vibration motor 61 is connected to the eccentric roller 67 by the universal joint 62, the first positioning block 69 will definitely be affected by the vibration force and vibrate. The irregular vibration can be offset by the universal joint 62, so the vibration force will not affect the vibration motor 61.

[0082] The backwash mechanism 7 includes a mounting frame 71 fixed to the inner wall of the processing box 13, a connecting plate 72 is fixed to the right side of the mounting frame 71, a longitudinally arranged connecting spring 73 is fixed to the outer wall of the connecting plate 72, a flushing plate 74 is fixed to the outer wall of the connecting spring 73, a hose 75 is staggeredly installed on the opposite side of the flushing plate 74 and the connecting plate 72 and between the connecting springs 73, and a liquid inlet pipe 76 is installed on the outer wall of the connecting plate 72.

[0083] See also Fig.11: When the sieve barrel 65 is vibrating, the user can connect an external water source in the liquid inlet pipe 76, and the water source needs to be pressurized. The external water will enter the flushing plate 74 through the hose 75, and the high-pressure water will be flushed on the sieve barrel 65 through the flushing plate 74, thus forming a backwashing function. The sieve barrel 65 in the vibrating state can also vibrate and relax the fine impurities on the inner wall. Then, after the flushing plate 74 flushes out the impurities, the impurities can all be collected at the bottom of the sieve barrel 65.

[0084] The first positioning block 69 is slidably connected to the first limit frame 63, the second positioning block 611 is slidably connected to the second limit frame 64, the bottom of the eccentric roller 67 is rotatably connected to the inner bottom of the mounting tube 66, the flushing plate 74 forms a one-way flow structure with the liquid inlet pipe 76 through the hose 75, and the outer wall of the flushing plate 74 is tightly fitted to the outer wall of the screen barrel 65.

[0085] In this embodiment: there will be more fine impurities in the wastewater after being treated by the flocculation box 31, so by adding a vibration mechanism 6 and a backwashing mechanism 7, the wastewater is subjected to secondary treatment through the vibration force generated by the rotation of the eccentric roller 67, and the fine impurities are left behind. The treated wastewater passes through the next step, and the impurities on the inner wall of the screen barrel 65 can be vibrated and loosened by vibration, and then flushed with a high-pressure flushing plate 74, so that the impurities and the screen barrel 65 can be quickly separated, ensuring that the inner wall of the screen barrel 65 is always clean, and the subsequent wastewater can flow through more efficiently.

[0086] Please refer again Fig.11 : It can be understood that the flushing plate 74 and the connecting plate 72 are connected by connecting springs 73. This connection method is used to offset the vibration force of the screen barrel 65 and ensure that the flushing plate 74 can always fit the outer wall of the screen barrel 65.

[0087] Third embodiment:

[0088] See also Figure 1 , Fig.12 and Fig.13 , further comprising a closing mechanism 8, a triggering mechanism 9 and a squeezing mechanism 10;

[0089] The bottom end of the treatment box 13 is connected to a sedimentation box 14, the closing mechanism 8 includes a rotating plate 81 rotatably connected to the inner wall of the sedimentation box 14 and arranged horizontally and equidistantly, the outer wall of the sedimentation box 14 is rotatably connected to connecting gears 82 arranged horizontally and equidistantly, the side wall of the sedimentation box 14 and above the rotating plate 81 is installed with a liquid outlet pipe 15, and the bottom of the sedimentation box 14 is installed with a waste pipe 17;

[0090] A water pump 18 is installed on the upper surface of the bottom plate 1 and below the treatment box 13. The water inlet end of the water pump 18 is sealed with the water outlet end of the treatment box 13. A delivery pipe 19 is sealed with the water outlet end of the water pump 18. The water outlet end of the delivery pipe 19 is sealed with the outer wall of the sedimentation box 14. An auxiliary material pipe 20 is installed on the upper surface of the sedimentation box 14.

[0091] The trigger mechanism 9 comprises a sleeve 91 fixedly mounted on the upper surface of the base plate 1, a piston rod 92 is slidably connected inside the sleeve 91, and a trigger rack 93 is fixedly mounted on the upper surface of the piston rod 92;

[0092] The squeezing mechanism 10 includes a mounting frame 101 fixed on the upper surface of the mounting plate 41, an oil bag 102 is placed inside the mounting frame 101, a pressure plate 104 is slidably connected to the inside of the mounting frame 101 and the outer wall of the oil bag 102, a return spring 105 is sleeved on the outer wall of the pressure plate 104, and an oil pipe 103 is sealed and installed on the outer wall of the oil bag 102.

[0093] See also Fig.12 and Fig.13 : In the first embodiment, if the cleaning mechanism 5 is not working at this time, the contact plate 52 is located at the far right;

[0094] The user can add solid flocculants into the sedimentation tank 14 through the auxiliary material pipe 20 . The solid flocculants enter the sedimentation tank 14 and mix with the wastewater to flocculate. The impurities after the secondary flocculation will settle at the bottom of the sedimentation tank 14 .

[0095] In the first embodiment, if the cleaning mechanism 5 is working at this time, the contact plate 52 will definitely move with the movement of the moving rack 51, and finally the contact plate 52 will squeeze the pressure plate 104 to control the compression of the oil bag 102 inside the mounting frame 101. When the oil bag 102 is squeezed by pressure, the internal liquid medium will enter the sleeve 91 through the oil pipe 103. The rising pressure inside the sleeve 91 will squeeze the control piston rod 92 to control the trigger rack 93 to rise. The rising of the trigger rack 93 will engage and drive the connecting gear 82 to rotate completely, thereby controlling the multiple rotating plates 81 to flip and close completely to isolate the internal partitions of the sedimentation box 14.

[0096] The left and right sides of the single rotating plate 81 are both arc structures, the axis of the connecting gear 82 is connected to the keyway at the center of the rotating plate 81, and the connecting gears 82 are meshed with each other.

[0097] The trigger rack 93 and one of the connecting gears 82 are meshed with each other, and the liquid outlet end of the oil pipe 103 and the outer wall of the sleeve 91 are sealed and connected.

[0098] It can be understood that the arc-shaped design can ensure that the wear on both sides of the rotating plate 81 can be minimized when the rotating plate 81 rotates and closes.

[0099] This embodiment: During the sedimentation process, the water and impurities inside the sedimentation box 14 will form layers. In this way, during the operation of the first embodiment, the multiple rotating plates 81 in the closing mechanism 8 will be synchronously driven to flip in conjunction, thereby isolating the upper and lower layered parts in the sedimentation box 14. In this way, the liquid outlet pipe 15 will definitely generate suction when discharging liquid, affecting the formation of suction water flow inside the sedimentation box 14. If this force is not isolated, it will definitely affect the impurities in the sedimentation, and may cause some impurities to be sucked into the liquid outlet pipe 15. Therefore, the layers are isolated through an integrated linkage method to ensure that the impurities can continue to settle at the bottom of the sedimentation box 14, and the treated wastewater can be completely discharged through the liquid outlet pipe 15.

[0100] Please refer to Figures 1 to 13 The working principle of the efficient wastewater treatment device for mechanical sand making provided by the present invention is as follows:

[0101] Step S1: flocculation of suspended impurities;

[0102] The driving motor 42 drives the key rod 45 to rotate. When the key rod 45 rotates, it will synchronously drive the half gear 46 to rotate. If the half gear 46 rotates counterclockwise, the tooth surface of the half gear 46 will first mesh with the second rack 49 to control the reciprocating ring 43 to pull the flocculation box 31 to move to the right. As the tooth surface of the half gear 46 rotates to the first rack 44, it will mesh with the reciprocating ring 43 to drive the flocculation box 31 to move from the right to the left. In this way, the continuous rotation of the half gear 46 will realize the left and right reciprocating motion of the flocculation box 31. The flocculation box 31 is in translation. During the movement, when it moves from left to right, the push rod 311 will be driven to move from left to right, so that the liquid flocculant can be slid inside the sleeve 310 to be extracted through the inlet pipe 315 and the first one-way valve 312 to enter the sleeve 310, and then when it moves from right to left, the push rod 311 will be pushed to move from right to left to squeeze the extracted liquid flocculant through the second one-way valve 313 into the feed pipe 314, and then the liquid flocculant will enter the flocculation box 31 through the feed pipe 314 to mix with the wastewater to achieve flocculation.

[0103] Step S2: After the first flocculation, the wastewater will continue to flow downward from the flocculation box 31 through the flexible pipe 16, and finally enter the treatment box 13 and the vibration mechanism 6. The water flow direction is in the screen barrel 65. When the wastewater enters the screen barrel 65, the user can start the vibration motor 61 to drive the universal joint 62 to rotate. The universal joint 62 transmits the rotational force to the eccentric roller 67 inside the mounting cylinder 66. When the eccentric roller 67 rotates, due to the different weights on both sides of the eccentric roller 67, vibration force will be generated under high-speed rotation. In this way, the wastewater passing through the screen barrel 65 will be vibrated and screened, and finer impurities will remain in the screen barrel 65.

[0104] The user starts the water pump 18 to pump the wastewater in the treatment tank 13 into the sedimentation tank 14 through the delivery pipe 19 .

[0105] Step S3: adding solid flocculants into the sedimentation tank 14 through the auxiliary material pipe 20. The solid flocculants enter the sedimentation tank 14 and mix with the wastewater for flocculation. The impurities after secondary flocculation will settle at the bottom of the sedimentation tank 14. During the sedimentation, the wastewater will be stratified, and the impurities will be present at the bottom of the sedimentation tank 14, while the finished water will remain above the sedimentation tank 14.

[0106] When the cleaning mechanism 5 is working, the contact plate 52 will definitely move with the movement of the moving rack 51, and finally the contact plate 52 will squeeze the pressure plate 104 to control the compression of the oil bag 102 inside the mounting frame 101. When the oil bag 102 is squeezed by pressure, the internal liquid medium will enter the sleeve 91 through the oil pipe 103. The rising pressure inside the sleeve 91 will squeeze the control piston rod 92 to control the trigger rack 93 to rise. The rising of the trigger rack 93 will engage and drive the connecting gear 82 to rotate completely, thereby controlling the multiple rotating plates 81 to flip and close completely to isolate the internal partitions of the sedimentation box 14.
