Description

Technical Field

[0001] The invention relates to the field of wastewater treatment sedimentation tanks, in particular to a sedimentation tank for pharmaceutical wastewater treatment and a use method thereof. Background Art

[0002] Medical wastewater is mainly sewage discharged from the hospital's treatment rooms, laboratories, wards, laundries and operating rooms. The source and composition of the sewage are very complex. Therefore, when discharging medical wastewater, it needs to be filtered first. Usually, the medical wastewater needs to be initially treated in a sedimentation tank during the treatment process.

[0003] The existing patent (publication number: CN114656015B) discloses a medical wastewater sedimentation and filtration device, including a housing, a water inlet pipe, a water outlet pipe, a first storage frame, a magnet and a filter. In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well solved: 1. During the use of the sedimentation tank, the sediment in the wastewater is quickly separated by adding flocculants.

[0022] A method for using a sedimentation tank for treating pharmaceutical wastewater comprises the following steps:

[0023] S1. When in use, wastewater is input into the sedimentation treatment box through the infusion tube, and then flocculant is added into the wastewater through the reagent delivery tube, and then the transmission motor is started to rotate the transmission rod, and the transmission rod rotates the support ring and the cleaning concave sleeve to stir the wastewater, and at the same time, the synchronous motor is started to rotate the reciprocating screw rod, so that the U-shaped transmission sleeve threadedly connected to the surface of the reciprocating screw rod cooperates with the transmission ring through the pull ring and drives the rotating support ring to reciprocate inside the sedimentation treatment box to stir the wastewater;

[0024] S2. After the wastewater is stirred and treated, the transmission motor is turned off and the sediment inside the wastewater is completely precipitated. The sewage without sediment is discharged through the drainage pipe, and the sediment is discharged from the sewage troughs on both sides of the sedimentation treatment box. At this time, the sediment will adhere to the inner wall of the sedimentation treatment box. At the same time, as the transmission rod stops rotating counterclockwise, the extrusion spring presses the rack to reset and move, so that the rack is meshed with the circular gear on the transmission rod and rotates clockwise with the special-shaped eccentric ring. When the flat end of the rotating special-shaped eccentric ring contacts the top surface of the circular limit block, the rotation direction of the transmission rod is positioned. At this time, the three cleaning concave sleeves on the side wall of the support ring are in a horizontal state with the inner wall corresponding to the sedimentation treatment box;

[0025] S3, then start the electric telescopic rod to retract, the two electric telescopic rods carry the adjusting rods to move in the direction away from the center of the support ring, the moving adjusting rods slide in cooperation with the corresponding adjusting grooves on the adjusting rings, so that the adjusting rings rotate on the side walls of the support rings. At this time, during the sliding process of the adjusting pins corresponding to the adjusting grooves on the surface of the adjusting rings, the cross plate in the middle of the adjusting pins moves along the trajectory of the strip sedimentation grooves, and then the cross plate carries the cleaning concave sleeve to move toward the inner wall direction of the sedimentation treatment box. During this process, the cross plate carries the L-shaped pull rod and the hinge block to move synchronously, so that the two hinge rods on the hinge block move with an opening trend, and the corresponding trapezoidal cleaning plates are translated along the trajectory of the moving grooves by the hinge rods. At this time, the trapezoidal cleaning plates extend from the inside of the cleaning concave sleeves. When the trapezoidal cleaning plates inside the three cleaning concave sleeves are all extended and overlap with the inner wall of the sedimentation treatment box, the side walls and bottom of the sedimentation treatment box can be brushed.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In the present invention, through the coordinated use of components such as the transmission rod, the sedimentation treatment box and the stirring and cleaning mechanism, when the transmission rod is in operation, it can drive the stirring and cleaning mechanism to mix the wastewater and the flocculant. After the wastewater is precipitated, the stirring and cleaning mechanism can be deformed, which is convenient for cleaning the sediment adhered to the inner wall of the sedimentation treatment box, avoiding a large amount of sediment remaining on the inner wall of the sedimentation treatment box after the wastewater sedimentation treatment, thereby improving the next wastewater sedimentation treatment effect.

[0028] In the present invention, through the coordinated use of components such as the transmission rod, the positioning mechanism and the cleaning sleeve, when the transmission rod stops rotating, the three cleaning sleeves can be made parallel to the corresponding sedimentation treatment boxes under the action of the positioning mechanism, so that the cleaning sleeves can carry the trapezoidal cleaning plates and stably fit the inner wall of the sedimentation treatment box to perform cleaning operations, thereby improving the cleaning effect.

[0029] In the present invention, through the deformation effect of the stirring and cleaning mechanism, the flocculation stirring component inside the sedimentation treatment box can perform the subsequent cleaning operation while realizing the flocculation stirring operation, thereby improving the functionality of the device.

[0040] 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 technical personnel in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 9 The present invention provides a technical solution: a sedimentation tank for treating pharmaceutical wastewater, comprising a sedimentation treatment box 1, a transmission rod 2 is rotatably connected to the lower part of the inner wall of the sedimentation treatment box 1, the right end of the transmission rod 2 penetrates the sedimentation treatment box 1 and is fixedly connected to a transmission motor 3, the surface of the transmission motor 3 is fixedly connected to the side wall of the sedimentation treatment box 1, and a positioning mechanism 4 is movably connected between the left end of the transmission rod 2 and the left side of the sedimentation treatment box 1. It should be noted that: when the transmission motor 3 is turned off, the transmission rod 2 can rotate with the rotating end of the transmission motor 3.

[0042] A stirring and cleaning mechanism 5 is movably connected between the middle of the transmission rod 2 and the inner wall of the sedimentation treatment box 1, a medicine delivery pipe 6 is fixedly connected to the top of the sedimentation treatment box 1, a liquid infusion pipe 7 is fixedly connected to the upper part of the front side of the sedimentation treatment box 1, a drainage pipe 8 is fixedly connected to the lower part of the front side of the sedimentation treatment box 1, and a sewage trough 9 is provided on both sides of the sedimentation treatment box 1. An isolation plate 10 is vertically slidably connected inside the sewage trough 9. The bottom of the isolation plate 10 passes through the sedimentation treatment box 1 and is fixedly connected to an electric push rod 11. The top of the electric push rod 11 is fixedly connected to the bottom of the sedimentation treatment box 1. It should be noted that after the wastewater in the sedimentation treatment box 1 is precipitated, the drainage pipe 8 is located above the sediment to prevent the sediment from being discharged during the drainage process of the drainage pipe 8, and a filter screen is arranged inside the drainage pipe 8.

[0043] The positioning mechanism 4 includes a support block 401, which is fixedly connected to the left side of the outer wall of the sedimentation treatment box 1. The surface of the support block 401 is symmetrically slidably connected with a connecting rod 402, a rack 403 is fixedly connected between the ends of the two connecting rods 402, and an extrusion spring 404 is movably sleeved in the middle of the connecting rod 402.

[0044] The left end of the transmission rod 2 passes through the sedimentation treatment box 1 and is fixedly sleeved with a special-shaped eccentric ring 405. A circular gear 406 is arranged between the right side of the special-shaped eccentric ring 405 and the left side of the sedimentation treatment box 1. The circular gear 406 is fixedly sleeved on the surface of the transmission rod 2, and the top of the circular gear 406 is meshed with the bottom of the rack 403. It should be noted that: when the transmission rod 2 rotates counterclockwise, the circular gear 406 on the surface of the transmission rod 2 is meshed with the corresponding rack 403, so that the rack 403 moves toward the support block 401, and the extrusion spring 404 is in a compressed state at this time; and when the rack 403 moves to the extreme position toward the support block 401, the rack 403 is released from the meshing with the circular gear 406, and the continuously rotating circular gear 406 keeps the rack 403 in the current state. The rack 403 in this state does not contact the side wall of the support block 401 to avoid interference.

[0045] The left side of the outer wall of the sedimentation treatment box 1 is fixedly connected with a spring telescopic rod 407, and the movable end of the spring telescopic rod 407 is fixedly connected with a circular stopper 408, and the side wall of the circular stopper 408 overlaps the side wall of the special-shaped eccentric ring 405. It should be noted that: when the transmission rod 2 rotates counterclockwise with the special-shaped eccentric ring 405, the arc surface of the special-shaped eccentric ring 405 contacts the arc surface of the circular stopper 408, so that the circular stopper 408 reciprocates with the spring telescopic rod 407; when the transmission rod 2 stops rotating, the extrusion spring 404 resets the rack 403, so that the rack 403 meshes with the circular gear 406 and rotates the transmission rod 2 clockwise, and at this time, the special-shaped eccentric ring 405 rotates and cooperates with the plane on the top of the circular stopper 408 to limit.

[0046] In this embodiment, Figures 1 to 9 As shown, the spring telescopic rod 407 is composed of a telescopic tube, a telescopic rod and a telescopic spring. The telescopic rod is set as a T-shaped rod. The telescopic rod is slidably connected inside the telescopic tube. The telescopic spring is fixedly connected between the end of the telescopic rod and the inner wall of the telescopic tube. It should be noted that: the end of the telescopic rod away from the telescopic spring is fixedly connected to the surface of the circular limit block 408.

[0047] A rectangular groove is provided at the bottom of the telescopic cylinder, and a rectangular block is fixedly connected to one end of the telescopic rod located inside the telescopic cylinder, and the rectangular block is slidably connected inside the rectangular groove. It should be noted that the rectangular groove and the rectangular block slide in cooperation to prevent the telescopic rod from rotating with the circular stopper 408 and affecting the use effect.

[0048] In this embodiment, Figures 1 to 9 As shown, the top of the circular stopper 408 is set as a plane that matches the plane end of the special-shaped eccentric ring 405. It should be noted that: when the special-shaped eccentric ring 405 rotates counterclockwise, the circular stopper 408 will not block or limit it, and when the special-shaped eccentric ring 405 rotates clockwise, the plane end of the special-shaped eccentric ring 405 fits with the top plane of the circular stopper 408. At this time, the circular stopper 408 blocks and limits the special-shaped eccentric ring 405, thereby positioning the rotation position of the transmission rod 2.

[0049] In this embodiment, Figures 1 to 9 As shown, the stirring and cleaning mechanism 5 includes a support ring 501, which is slidably connected to the middle part of the transmission rod 2, and three strip grooves 502 are equidistantly provided on the right side of the support ring 501. A through strip groove 503 is provided on the surface of the support ring 501, and the through strip groove 503 and the three strip grooves 502 are equidistantly distributed along the circumference.

[0050] An adjustment ring 504 is arranged on the right side of the support ring 501. The adjustment ring 504 is movably sleeved on the surface of the transmission rod 2. Four adjustment grooves 505 are equidistantly arranged on the surface of the adjustment ring 504 along the circumference. The three bar-shaped recessed grooves 502 and the through bar-shaped recessed grooves 503 correspond to the four adjustment grooves 505 one by one. An adjustment pin 506 is slidably connected inside the bar-shaped recessed grooves 502. One end of the adjustment pin 506 is slidably connected inside the corresponding adjustment groove 505. An adjustment rod 507 is slidably connected inside the through bar-shaped recessed grooves 503. The adjustment rod 507 is movably inserted inside the corresponding adjustment groove 505. It should be noted that the adjustment pin 506 is set to a T-shape. The position of the adjustment ring 504 is limited by the T-shaped adjustment pin 506 to ensure the stability of the adjustment ring 504 during use.

[0051] The left and right sides of the transmission rod 2 are fixedly sleeved with convex connecting plates 508, and the surface of the convex connecting plate 508 is fixedly connected with an electric telescopic rod 509, and the two electric telescopic rods 509 correspond to the two ends of the adjustment rod 507 one by one, and the movable ends of the electric telescopic rods 509 are fixedly connected to the ends of the adjacent adjustment rods 507. It should be noted that the electric telescopic rods 509 are set as a multi-stage electric telescopic rod 509 structure, which is convenient for the electric telescopic rods 509 to move with the adjustment rods 507 during the extension and retraction of the side walls of the convex connecting plate 508.

[0052] A horizontal plate 510 is fixedly connected to the middle part of the adjusting pin 506, and the horizontal plate 510 is arranged between the supporting ring 501 and the adjusting ring 504. A cleaning sleeve 511 is fixedly connected to one end of the horizontal plate 510, and a trapezoidal cleaning plate 512 is symmetrically slidably connected inside the cleaning sleeve 511. Moving grooves 513 are symmetrically opened on the side walls of the cleaning sleeve 511. The two moving grooves 513 correspond one to one to the two trapezoidal cleaning plates 512. A moving pin 514 is slidably connected inside the moving groove 513. One end of the moving pin 514 is fixedly connected to the surface of the corresponding trapezoidal cleaning plate 512, and the end of the moving pin 514 away from the trapezoidal cleaning plate 512 is hinged with a hinge rod 515. It should be noted that bristles are provided on the side of the cleaning sleeve 511 and the trapezoidal cleaning plate 512 close to the inner wall of the sedimentation treatment box 1, and steel balls are provided on the surface of the trapezoidal cleaning plate 512. The surface of the steel balls overlaps with the inner wall of the cleaning sleeve 511 to reduce the friction resistance of the trapezoidal cleaning plate 512 during its movement inside the cleaning sleeve 511.

[0053] The surfaces of the three horizontal plates 510 are fixedly connected with L-shaped pull rods 516, and three hinge blocks 517 are equidistantly slidably connected to the left side of the support ring 501. The three hinge blocks 517 correspond one by one to the three horizontal plates 510. One end of the L-shaped pull rod 516 is fixedly connected to the middle part of the corresponding hinge block 517, and the end of the hinge rod 515 away from the movable pin 514 is hinged to the side wall of the adjacent hinge block 517. It should be noted that: a movable groove 513 is opened on the left side of the support ring 501, and a movable block is fixedly connected to the surface of the hinge block 517, and the hinge block 517 is slidably connected to the inside of the corresponding movable groove 513 through the movable block; when the horizontal plate 510 moves toward the center of the support ring 501 with the L-shaped pull rod 516, the L-shaped pull rod 516 moves synchronously with the hinge block 517 and the hinge rod 515. At this time, the hinge rod 515 pulls the hinged trapezoidal cleaning plate 512 to slide inside the movable groove 513, so that the trapezoidal cleaning plate 512 is retracted into the inside of the cleaning recess 511, and conversely, the trapezoidal cleaning plate 512 can extend from the inside of the cleaning recess 511.

[0054] A reciprocating screw 518 is rotatably connected to the upper part of the inner wall of the sedimentation treatment box 1, and a U-shaped transmission sleeve 519 is threadedly connected to the surface of the reciprocating screw 518. Pull rings 520 are fixedly connected to both sides of the U-shaped transmission sleeve 519, and the two pull rings 520 correspond to the two sides of the support ring 501 one by one. The side walls of the pull rings 520 are rotatably connected to the transmission ring 521, and the side walls of the two transmission rings 521 are respectively fixedly connected to the two sides of the support ring 501. The right end of the reciprocating screw 518 passes through the sedimentation treatment box 1 and is fixedly connected to a synchronous motor 522, and the surface of the synchronous motor 522 is fixedly connected to the side wall of the sedimentation treatment box 1. It should be noted that the distance from the reciprocating screw 518 to the axis of the transmission rod 2 is set to 1.2 times the distance from the axis of the transmission rod 2 to the bottom surface of the sedimentation treatment box 1, so as to avoid interference between the cleaning sleeve 511 and the trapezoidal cleaning plate 512 and the reciprocating screw 518 after they are unfolded; when the synchronous motor 522 is started to rotate the reciprocating screw 518, the U-shaped transmission sleeve 519 moves back and forth on the surface of the transmission rod 2 with the support ring 501 through the pull ring 520.

[0055] In this embodiment, Figures 1 to 9 As shown, both sides of the transmission rod 2 are provided with slide grooves, and the inner ring of the support ring 501 is symmetrically fixedly connected with sliders, and the two sliders are respectively slidably connected inside the two slide grooves. It should be noted that: the surface of the slider is fixedly connected with a ball, and the surface of the ball overlaps the inner wall of the slide groove, reducing the friction resistance of the support ring 501 sliding on the surface of the transmission rod 2.

[0056] In this embodiment, Figures 1 to 9 As shown, a moving groove 513 is formed on the surface of the convex connecting plate 508 , and the end of the adjusting rod 507 is slidably connected to the inside of the corresponding moving groove 513 .

[0057] In this embodiment, Figures 1 to 9 As shown, mounting pins are fixedly connected to both sides of the support ring 501, and the side walls of the transmission ring 521 are fixedly connected to the ends of the mounting pins.

[0058] A connecting bearing is fixedly connected between the surface of the transmission ring 521 and the surface of the pull ring 520. It should be noted that through the setting of the connecting bearing, when the support ring 501 rotates with the transmission ring 521, the transmission ring 521 will not rotate with the pull ring 520 to avoid interference.

[0059] In this embodiment, Figures 1 to 9 As shown, a method for using a sedimentation tank for treating pharmaceutical wastewater comprises the following steps:

[0060] S1. When in use, wastewater is input into the sedimentation treatment box 1 through the infusion tube 7, and then flocculant is added into the wastewater through the reagent delivery tube 6. Then, the transmission motor 3 is started to rotate the transmission rod 2, and the transmission rod 2 rotates the support ring 501 and the cleaning concave sleeve 511 to stir the wastewater. At the same time, the synchronous motor 522 is started to rotate the reciprocating screw rod 518, so that the U-shaped transmission sleeve 519 threadedly connected to the surface of the reciprocating screw rod 518 cooperates with the transmission ring 521 through the pull ring 520 to drive the rotating support ring 501 to reciprocate inside the sedimentation treatment box 1 to stir the wastewater.

[0061] S2. After the wastewater is stirred and treated, the transmission motor 3 is turned off and the sediment inside the wastewater is completely precipitated. Then, the sewage without sediment is discharged through the drainage pipe 8, and the sediment is discharged from the sewage troughs 9 on both sides of the sedimentation treatment box 1. At this time, the sediment will adhere to the inner wall of the sedimentation treatment box 1. At the same time, as the transmission rod 2 stops rotating counterclockwise, the extrusion spring 404 presses the rack 403 to reset, so that the rack 403 is meshed with the circular gear 406 on the transmission rod 2 and rotates clockwise with the special-shaped eccentric ring 405.
