Benefits of technology

[0018]1. This invention uses a conveying mechanism to transport a clean hopper from the first storage tank to the top of the collection cylinder. When the hopper is above the collection cylinder, a docking mechanism connects the hopper to the collection cylinder, allowing waste liquid to be poured into the hopper. The waste liquid then flows from the hopper into the collection cylinder. After the waste liquid is poured out, the drive mechanism is restarted, which drives the conveying mechanism to run again. The conveying mechanism then transports a new hopper from the first storage tank to the right. Simultaneously, the docking mechanism releases the used hopper. When the new hopper moves to the top of the collection cylinder, the docking mechanism connects the new hopper to the collection cylinder. At this point, the collection cylinder pushes the used hopper into the second storage tank. Once the used hopper is inside the second storage tank, the second storage tank blocks its top and bottom openings, effectively preventing harmful substances in the waste liquid remaining on the hopper from evaporating into the air and causing air pollution.

[0033] Please see Figure 1-12 The present invention provides a technical solution: a medical laboratory waste liquid collection and purification treatment device, including a base plate 1, a collection cylinder 2 provided on the base plate 1, and support plates 3 symmetrically fixedly connected to the left and right sides of the collection cylinder 2 on the base plate 1. A first storage box 4 and a second storage box 5 are respectively fixedly connected to the left and right support plates 3. The first storage box 4 and the second storage box 5 are respectively used to store clean hoppers 6 and used hoppers 6. The hoppers 6 are used to dock with the collection cylinder 2 to facilitate the pouring of waste liquid, and the hoppers 6 have a downward one-way flow valve body inside.

[0034] A docking mechanism is provided above the collecting cylinder 2. The docking mechanism is used to open the collecting cylinder 2 and dock the hopper 6, which is located above the collecting cylinder 2, with the collecting cylinder 2; after the hopper 6 leaves the collecting cylinder 2, the docking interface of the collecting cylinder 2 is closed.

[0035] The first storage box 4 is equipped with a conveying mechanism, which is used to transport the hopper 6 in the first storage box 4 to the position above the collection cylinder 2 and to transport the hopper 6 at the position above the collection cylinder 2 to the second storage box 5.

[0036] The base plate 1 is equipped with a drive mechanism, which is used to drive the conveying mechanism and the docking mechanism to operate sequentially.

[0037] During operation, when dumping waste liquid, the drive mechanism is activated first, which in turn drives the conveying mechanism and the docking mechanism to run sequentially. The conveying mechanism transports the clean hopper 6 from the first storage tank 4 to the upper position of the collection cylinder 2. When the hopper 6 is above the collection cylinder 2, the docking mechanism connects the hopper 6 to the collection cylinder 2, allowing the waste liquid to be poured into the hopper 6. The waste liquid then flows along the hopper 6 and finally into the collection cylinder 2. After the waste liquid is dumped, the drive mechanism is activated again, which drives the conveying mechanism to run again. The mechanism will transport the new hopper 6 in the first storage box 4 to the right, while the docking mechanism will release the used hopper 6. When the new hopper 6 moves to the position above the collection cylinder 2, the docking mechanism will dock the new hopper 6 with the collection cylinder 2. At this time, the collection cylinder will push the used hopper 6 into the second storage box 5. After the used hopper 6 enters the second storage box 5, the second storage box 5 can block its upper and lower openings, which can effectively prevent the harmful substances contained in the waste liquid remaining on the hopper 6 from volatilizing into the air and causing air pollution.

[0038] like Figure 3-4 , Figure 11 As shown, as a further embodiment of the present invention, the docking mechanism includes a docking joint 7, which is fixedly connected to the collecting cylinder 2, and a sealing plate 8 is symmetrically slidably connected to the front and rear sides above the docking joint 7. The sealing plate 8 is sealed and fitted to the surface of the docking joint 7. A first spring 9 is symmetrically fixedly connected to the left and right sides of the sealing plate 8, and the first spring 9 is fixedly connected to the docking joint 7. A first push block 10 is fixedly connected to the sealing plate 8. Two first slide rails 11 are fixedly connected to the left and right sides of the docking joint 7.

[0039] The bottom front and rear sides of the first storage box 4 and the second storage box 5 are symmetrically and fixedly connected with second slide rails 12. The base of the hopper 6 is slidably connected to the two second slide rails 12, and the left and right sides of the hopper 6 are symmetrically and fixedly connected with second push blocks 13. The second push blocks 13 are located above the first push blocks 10. The second slide rails 12 and the first slide rails 11 on the connector are on the same straight line.

[0040] The inner part of the sealing plate 8 is grooved and the middle part of the groove is raised; the front and rear sides of the base of the hopper 6 are raised and the raised parts slide in fit with the groove of the inner part of the sealing plate 8; the middle part of the raised part of the base of the hopper 6 is grooved and the groove on the base of the hopper 6 engages with the raised part on the sealing plate 8.

[0041] During operation, by pushing the first push blocks 10 on both the front and rear sides, the first push blocks 10 on both the front and rear sides can drive the sealing plates 8 on both the front and rear sides to move forward and backward respectively. At this time, the opening of the collecting cylinder 2 will be gradually opened. When the distance between the sealing plates 8 on the front and rear sides is greater than the width of the hopper 6 base, the hopper 6 can be driven to slide along the second slide rail 12 onto the first slide rail 11. When the hopper 6 slides to the middle position on the connector 7, the force of pushing the two first push blocks 10 is released. Under the action of the first spring 9, the sealing plates 8 on both the front and rear sides automatically reset and clamp the base of the hopper 6. At this time, the concave part on the base of the hopper 6 is locked with the protruding part on the sealing plate 8, and the hopper 6 can be locked on the connector 7 relatively stably.

[0042] like Figure 6-9 , Figure 11 As shown, as a further embodiment of the present invention, the conveying mechanism includes a sliding frame 14, which is attached to the surface of the first storage box 4 and slidably connected to the first storage box 4; a fixed frame 15 is fixedly connected to the right end portion of both the front and rear sides of the sliding frame 14, and a slider 16 is slidably connected inside the fixed frame 15, with a first push rod 17 fixedly connected to the slider 16; the distance between the right end portions of the first push rods 17 on the left and right sides is less than the distance between the two first push blocks 10, and the distance between the left end portions of the first push rods 17 on the left and right sides is greater than the distance between the two first push blocks 10. A second push rod 41 is fixedly connected to the left side of the sliding frame 14. The working end of the second push rod 41 is at the same height as the base of the hopper 6, and the length of the second push rod 41 is adjustable. A moving mechanism is provided on the first push rod 17. The moving mechanism is used to pull the hopper 6 in the first storage box 4 to the right when the first push rod 17 moves to the right. A reset mechanism is provided on the first storage box 4. The reset mechanism is used to drive the first push rod 17 upward past the first push block 10 when the sliding frame 14 resets from right to left, and to drive the first push rod 17 downward to return to its original position after the sliding frame 14 has fully reset.

[0043] The moving mechanism includes a pull rod 18, the right end of which is fixedly connected to the right side of the first push rod 17 and the pull rod 18 is located above the first push block 10; the left end of the pull rod 18 is bent inward and the bent part is located to the left of the second push block 13 on the rightmost hopper 6 inside the first storage box 4.

[0044] During operation, when the sliding frame 14 slides to the right, it drives the two first push rods 17 to move to the right. Simultaneously, the first push rods 17 drive the pull rod 18 to move to the right. As the pull rod 18 moves to the right, it pulls the second push block 13 on the hopper 6, causing the hopper 6 in the first storage box 4 to move to the right. When the first push rods 17 on both the front and rear sides move to a certain degree to the right, the inclined portions of the first push rods 17 on both the front and rear sides begin to engage with the first push blocks 10 on both the front and rear sides, respectively. As the first push rods 17 continue to move to the right, the first push rods 17 on both the front and rear sides push the first push blocks 10 on both the front and rear sides forward and backward, respectively. When the inclined portions of the first push rods 17 pass the first push blocks 10, the first push rods 17 on both the front and rear sides... The first push block 10 initially remains stationary, and the distance between the sealing plates 8 on the front and rear sides is greater than the width of the hopper 6 base. As the first push rods 17 on the front and rear sides continue to move, the pull rods 18 on the front and rear sides pull the hopper 6 to move above the collecting cylinder 2. When the hopper 6 is completely moved to the position directly above the collecting cylinder 2, the first push rod 17 just passes the first push block 10, and the sealing plates 8 on the front and rear sides reset to clamp the hopper 6 base. At the same time, the sliding frame 14 drives the second push rod 41 to the deepest position inside the first storage box 4. The second push rod 41 pushes all the hoppers 6 in the first storage box 4 forward. When the second push rod 41 exits the first storage box 4, a new hopper 6 can be added from the left end of the first storage box 4.

[0045] like Figure 6-10 As shown, as a further embodiment of the present invention, the reset mechanism includes two second springs 19, which are sleeved on the front and rear sides of the sliding frame 14; one end of each second spring 19 is fixedly connected to the sliding frame 14 and the other end is fixedly connected to the first storage box 4; a threaded rod 20 is provided inside the fixed frame 15, which is rotatably connected to the fixed frame 15 and threadedly connected to the slider 16; the threaded rod 20 does not have self-locking properties, and a gear 21 and a ratchet 22 are coaxially fixedly connected to the bottom end of the threaded rod 20, with the ratchet 22 meshing with... The first storage box 4 is equipped with a pawl 23, which is slidably connected to the fixed frame 15. A third spring 24 is fitted on the pawl 23, with one end of the third spring 24 fixedly connected to the pawl 23 and the other end fixedly connected to the fixed frame 15. A third push block 25 is fixedly connected to the upper end of the pawl 23. A third push rod 26 is symmetrically fixedly connected to the front and rear sides of the first storage box 4, and the third push rod 26 is in contact with the third push block 25. A rotating mechanism is provided on the right side of the gear 21, which is used to drive the gear 21 to rotate when the gear 21 moves from right to left.

[0046] The rotating mechanism includes a fixed frame 27, which is fixedly connected to the first storage box 4. Racks 28 are symmetrically slidably connected to the front and rear sides of the fixed frame 27. A fourth spring 29 is fixedly connected to the rack 28 at the connection point with the fixed frame 27, and the bottom end of the fourth spring 29 is fixedly connected to the fixed frame 27. Push plates 30 are provided on the front and rear sides of the front and rear sealing plates 8. Both push plates 30 are slidably connected to the fixed frame 27, and a connecting rod 31 is rotatably connected to the upper part of the push plate 30. The lower parts of the connecting rods 31 are rotatably connected to the racks 28 on the front and rear sides, respectively. The racks 28 and gears 21 are at the same height, and the racks 28 on the front and rear sides mesh with the gears 21 on the front and rear sides, respectively.

[0047] During operation, when the hopper 6 moves above the collecting cylinder 2, the force pushing the sliding frame 14 is removed, and the sliding frame 14 begins to move to the left and reset under the action of the second springs 19 on both the front and rear sides. When the first push rods 17 on both the front and rear sides move to the right, they will push the sealing plates 8 on both the front and rear sides to move forward and backward respectively. When the sealing plates 8 on both the front and rear sides move, they will push the push plates 30 on both the front and rear sides to move forward and backward respectively. When the push plates 30 move, they will push the rack 28 downward through the connecting rod 31. When the rack 28 moves downward, it will no longer mesh with the gear 21. Therefore, when the gear 21 moves to the right, it will not mesh with the rack 28. When the first push rod 17 passes the first push block 10, the sealing plates 8 on both the front and rear sides reset, and the racks 28 on both the front and rear sides automatically reset under the action of the fourth spring 29.

[0048] As the sliding frame 14 moves to the left, it drives the gears 21 on both sides to move to the left. The gears 21 start to rotate under the action of the rack 28 and drive the threaded rod 20 to rotate. The threaded rod 20 then drives the slider 16 to slide upward within the fixed frame 15. The slider 16 then drives the first push rod 17 and the pull rod 18 to move upward. When the inclined part of the first push rod 17 moves again to a position close to the first push block 10, the gear 21 disengages from the rack 28. At this time, the first push rod 17 is exactly above the first push block 10, and the pull rod 18 is at the top of the second push block 13.

[0049] After the sliding frame 14 is fully reset, the third push block 25 on the fixed frame 15 comes into contact with the third push rod 26 on the first storage box 4 and moves away from the ratchet 22 under the action of the third push rod 26. When the third push block 25 moves, it drives the pawl 23 to move. The pawl 23 disengages from the ratchet 22, and the threaded rod 20 can rotate in the opposite direction. Since the threaded rod 20 does not have self-locking properties, after the pawl 23 disengages from the ratchet 22, the slider 16, the first push rod 17 and the pull rod 18 begin to automatically descend to the initial height. The bent part at the left end of the pull rod 18 falls exactly to the left side of the second push rod 41 on the hopper 6 inside the first storage box 4.

[0050] like Figure 5 , Figure 7-8 As shown, as a further embodiment of the present invention, the driving mechanism includes a pull rope 32, which is fixedly connected to the left side of the sliding frame 14; a guide wheel 33 is rotatably connected to the bottom right side of the first storage box 4, and a spool 34 is provided at the bottom of the guide wheel 33; the pull rope 32 passes through the guide wheel 33 and is fixedly connected to the spool 34; the spool 34 is rotatably connected to the base plate 1, and a first pulley 35 is fixedly connected to the front end of the spool 34, and a belt 36 is provided on the first pulley 35; a second pulley 37 is provided at the front side of the collection cylinder 2, and the second pulley 37 is rotatably connected to the base plate 1; the diameter of the first pulley 35 is smaller than the diameter of the spool 34 and the second pulley 37; the belt 36 meshes with both the first pulley 35 and the second pulley 37, and a first rotating rod 38 is rotatably connected to the front end of the second pulley 37;

[0051] The bottom of the first rotating rod 38 is provided with a second rotating rod 39. The second rotating rod 39 is equal in length to the first rotating rod 38 and parallel to each other. The second rotating rod 39 is rotatably connected to the base plate 1. The front of the second pulley 37 is provided with a foot pedal 40. The foot pedal 40 is rotatably connected to the end positions of the first rotating rod 38 and the second rotating rod 39.

[0052] During operation, after emptying the waste liquid, the user presses down the foot pedal, which in turn drives the first rotating rod 38 to rotate downwards. The first rotating rod 38 drives the second pulley 37 to rotate, and the second pulley 37 drives the first pulley 35 to rotate via the belt 36. The first pulley 35 drives the spool 34 to rotate, and the spool 34 begins to wind up the pull rope 32. Under the action of the guide wheel 33, the pull rope 32 begins to pull the sliding frame 14 to slide to the right, thereby achieving the effect of changing the hopper 6.
