Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a waste liquid treatment device for pharmaceutical production. Background Technology

[0002] Pharmaceutical production generates a significant amount of waste liquid, which may contain harmful substances that pollute the environment. To reduce environmental pollution, the waste liquid is collected and treated. Traditional waste liquid treatment devices directly discharge the waste liquid into the neutralizing agent during the treatment process. However, this method is difficult to control the dosage, resulting in waste of the neutralizing agent and significantly increasing the overall operating cost.

[0003] To address the aforementioned issues, Chinese Patent No. CN222312854U discloses a waste liquid collection and treatment device for pharmaceutical experimental teaching. This device includes an L-shaped mounting block with a waste liquid tank fixedly connected to its side wall. The waste liquid tank is hollow inside. A second rotating shaft is rotatably connected to the inner side wall of the mounting block via a bearing. A turntable is fixedly connected to one end of the second rotating shaft inside the mounting block. A smooth rod is fixedly connected to the side wall of the turntable. A sliding block is slidably connected between the top and bottom inner walls of the mounting block, and a sliding hole is provided on the side wall of the sliding block. This waste liquid collection and treatment device controls the use of the neutralizing agent by quantitatively extracting and mixing waste liquid and a neutralizing agent, thus reducing waste during the use of the neutralizing agent.

[0004] The above-mentioned waste liquid collection and treatment device has the following problems during actual use: the filter screen can filter the impurities in the waste liquid and avoid clogging the first connecting pipe. However, as the usage time increases, more and more impurities will accumulate on the filter screen. Since the filter screen is located inside the waste liquid tank, it is inconvenient to disassemble and replace it. If it is not cleaned, it will cause the filter screen to become clogged, which will directly affect the speed at which the waste liquid enters the first connecting pipe, thereby reducing the waste liquid treatment efficiency. Summary of the Invention

[0005] The present invention aims to provide a waste liquid treatment device for pharmaceutical production, in order to solve the problem that the filter screen will become clogged after long-term use of existing devices, thereby reducing the waste liquid treatment efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste liquid treatment device for pharmaceutical production, comprising a treatment tank, a side opening on the side wall of the treatment tank, and a door panel rotatably connected to the side opening; an inner tank with a top opening on both sides inside the treatment tank, an unloading port on the inner tank, and a sealing block detachably connected to the unloading port; a partition inside the inner tank, and a filter section on both sides of the top of the partition, the filter section including filter holes vertically opened on the partition, and a filter screen inside the filter holes; a waste liquid pipe passing through the treatment tank is connected to the inner tank, the waste liquid pipe being located above the partition; and also includes an introduction mechanism for introducing neutralizing drugs into the two inner tanks and a cleaning mechanism for cleaning the filter screens inside the two inner tanks.

[0007] Furthermore, the introduction mechanism includes a medicine tank, piston cylinders located on both sides of the medicine tank, and a movable block. Both the medicine tank and the piston cylinders are fixedly connected to the inner wall of the treatment tank. An inlet pipe and an outlet pipe are connected to the piston cylinders. The end of the inlet pipe away from the piston cylinder is connected to the medicine tank, and the end of the outlet pipe away from the piston cylinder is connected to the inner tank. A piston block is slidably connected inside the piston cylinder, and the piston block is fixedly connected to the movable block. It also includes a drive unit for driving the movable block to move laterally and reciprocally.

[0008] Furthermore, the drive unit includes a rotating shaft rotatably connected to the processing box, a drive unit for driving the rotating shaft to rotate, a first cylindrical cam coaxially connected to the rotating shaft, a first curved groove provided on the first cylindrical cam, a first auxiliary block slidably connected in the first curved groove, and the first auxiliary block fixedly connected to the movable block.

[0009] Furthermore, the cleaning mechanism includes processing units located on both sides inside the processing box. Each processing unit includes a round shaft rotatably connected to a partition and a transverse block slidably connected to the inner box. A cam body is coaxially connected to the round shaft. The side wall of the transverse block is provided with a wall groove, which is located between two filter holes. The cam body abuts against the two sides of the wall groove and can rotate within the wall groove. Support blocks are connected to both sides of the wall groove on the transverse block. The top of the support blocks is provided with a brush layer for cleaning the filter screen. The mechanism also includes a power unit for simultaneously driving the two round shafts to rotate.

[0010] Furthermore, the power unit includes a worm gear coaxially connected to both ends of the rotating shaft and a worm wheel coaxially connected to the round shaft. The worm gear is rotatably connected to the processing box, and the worm wheel meshes with the worm gear.

[0011] Furthermore, several stirring arms are vertically arranged on the circular shaft, and the stirring arms are located below the partition.

[0012] Furthermore, a fixed plate is provided on the inner wall of the inner box, and the round shaft is rotatably connected to the fixed plate; both sides of the fixed plate are provided with grooves, and a side shaft is rotatably connected in the grooves. A torsion spring is provided between the side shaft and the groove, and a swing arm is sleeved on the side shaft. The two swing arms are located on both sides of the round shaft respectively; both sides of the bottom of the transverse block are provided with bottom blocks for pressing the swing arms, and the swing arms are located on the movement trajectory of the bottom blocks.

[0013] Furthermore, vertical grooves are provided on both sides of the transverse block located in the wall groove, and the bearing block is vertically slidably connected to the vertical groove; it also includes a linkage mechanism that drives the two bearing blocks to move vertically at the same time as the circular shaft rotates.

[0014] Furthermore, the linkage mechanism includes a second cylindrical cam coaxially connected to the round shaft and a side block fixedly connected to the bearing block. The second cylindrical cam is provided with a second curved groove, and a second auxiliary block is slidably connected to both sides of the second curved groove. The second auxiliary block is provided with a lifting block, and the lifting block is vertically slidably connected to the partition. The lifting block is provided with a linkage block, which is located between the partition and the transverse block. The linkage block is provided with a linkage groove, and the side block is located in the linkage groove, and the side block is in frictional contact with the linkage groove.

[0015] The principles and advantages of this scheme are: 1. In this solution, the waste liquid is collected at the bottom of the inner tank through a filter screen, which can filter out impurities in the waste liquid. Then, a neutralizing agent is introduced into the inner tank, so that the waste liquid and the neutralizing agent are mixed and purified in the inner tank. Compared with the existing technology, the horizontal block drives the brush layer to move horizontally back and forth, and the brush layer cleans the filter screen and avoids filter screen clogging.

[0016] 2. The brush layer in this design can move horizontally back and forth, thus cleaning the filter screen and preventing it from clogging. In addition, the brush layer can also move vertically back and forth, allowing it to pass through the filter screen, lift up the debris on the screen, and turn it over, thus preventing debris from blocking or clogging the filter screen and ensuring the unobstructed flow of the filter screen, which means that the waste liquid can continuously pass through the filter screen.

[0017] 3. During the rotation of the shaft in this design, the shaft drives the piston block to reciprocate within the piston cylinder via the first cylindrical cam, the first curved groove, the first auxiliary block, and the movable block. This allows the neutralizing agent in the liquid tank to be introduced into the inner tank through the inlet pipe, the piston cylinder, and the outlet pipe. During the rotation of the shaft, the shaft also drives the stirring arm to rotate via the worm, worm wheel, and round shaft. The stirring arm mixes the waste liquid and neutralizing agent in the inner tank, accelerating the purification of the waste liquid. Therefore, during the rotation of the shaft, it can introduce the neutralizing agent into the inner tank and also mix and purify the waste liquid and neutralizing agent in the inner tank, making it highly practical.

[0018] 4. During the horizontal reciprocating motion of the movable block in this solution, it can simultaneously drive the two piston blocks to reciprocate horizontally, thereby introducing the neutralizing medicine in the medicine tank into the two inner tanks respectively, and simultaneously purifying the waste liquid in the two inner tanks, thus improving the purification efficiency of the waste liquid.

[0019] 5. During the rotation of the circular shaft in this solution, the shaft drives the stirring arm to mix the waste liquid and neutralizing agent in the inner tank. During the rotation of the circular shaft, the shaft also drives the cam body to rotate. The cam body drives the transverse block to move laterally and reciprocally through the wall groove. The transverse block drives the bottom block to move synchronously, so that the bottom block can intermittently squeeze the swing arm, causing the torsion spring to deform. This allows the swing arm to swing back and forth, thereby stirring the waste liquid and neutralizing agent on both sides of the circular shaft, promoting the mixing and purification of the two, and expanding the mixing and purification range. Therefore, this solution can mix and purify the waste liquid and neutralizing agent in two ways, enhancing the purification effect and improving the purification efficiency.

[0020] 6. During the rotation of the circular shaft in this solution, the circular shaft can drive the stirring arm to rotate for mixing. The circular shaft can also cause the swing arm to swing back and forth through the cam body, horizontal block, bottom block, swing arm, and torsion spring, thus achieving mixing. The circular shaft can also drive the bearing block and brush layer to move vertically back and forth through the second cylindrical cam, second auxiliary block, lifting block, linkage block, linkage groove, and side block. This allows the brush layer to pass through the filter screen, cleaning the filter screen and lifting up debris on the filter screen, turning over the debris to prevent it from blocking or clogging the filter screen. Therefore, during the rotation of the circular shaft, waste liquid and neutralizing medicine can be mixed and the filter screen can be cleaned, making it highly practical.

[0028] On both sides of the wall groove 53, there are support blocks 60 connected to the horizontal block 51. Specifically, vertical grooves 61 are opened on both sides of the horizontal block 51 located in the wall groove 53, and the support blocks 60 are vertically slidably connected to the vertical grooves 61.

[0029] A fixing plate 70 is fixedly connected to the inner wall of the inner box 20. The fixing plate 70 is located below the transverse plate. The round shaft 50 is rotatably connected to the fixing plate 70. Grooves 71 are opened on both sides of the fixing plate 70. A side shaft 72 is rotatably connected in the groove 71.

The upper end of the swing arm 73 is located on the movement trajectory of the bottom block 74. The distance between the two bottom blocks 74 is greater than the distance between the upper ends of the two swing arms 73.

[0030] The specific implementation process is as follows: When in use, introduce sufficient neutralizing medicine into the medicine tank 30, rotate the door panel 12 so that the door panel 12 blocks the side opening 11; introduce the waste liquid into the waste liquid pipe 24 so that the waste liquid enters the inner tank 20, the waste liquid falls on the partition 22, and the waste liquid is collected at the bottom of the inner tank 20 through the filter screen 23 so that the impurities are filtered on the surface of the partition 22.

[0031] When the motor 43 is started, the output shaft of the motor 43 drives the drive gear 44 to rotate. The drive gear 44 meshes with the driven gear 45 to drive the rotating shaft 40 to rotate. The rotating shaft 40 drives the first cylindrical cam 41 to rotate. The first cylindrical cam 41 drives the movable block 32 to move laterally and reciprocally through the first curved groove and the first auxiliary block 42. The movable block 32 drives the two piston blocks 35 in the two piston cylinders 31 to move laterally and reciprocally. In this way, the neutralizing medicine in the medicine tank 30 can be introduced into the inner box 20 through the inlet pipe 33, the piston cylinder 31, and the outlet pipe 34. That is, the neutralizing medicine in the medicine tank 30 can be introduced into the two inner boxes 20 in multiple times.

[0032] During the rotation of the rotating shaft 40, the rotating shaft 40 drives the worm gear 54 to rotate. The worm gear 54 meshes with the worm wheel 55 to drive the round shaft 50 to rotate. The round shaft 50 drives the stirring arm 56 to rotate, thereby mixing and purifying the waste liquid and neutralizing medicine in the inner box 20.

[0033] During the rotation of the round shaft 50, the round shaft 50 drives the cam body 52 to rotate, so that the cam body 52 rotates in the wall groove 53. The cam body 52 drives the transverse block 51 to move laterally and reciprocally through the wall groove 53. The transverse block 51 drives the bristle layer 62 to move laterally and reciprocally through the bearing block 60. That is, the bristle layer 62 can be used to clean the filter screen 23 and prevent the filter screen 23 from clogging.

[0034] During the transverse reciprocating motion of the transverse block 51, the transverse block 51 drives the bottom block 74 to reciprocate laterally, causing the bottom block 74 to intermittently squeeze the swing arm 73. When the bottom block 74 squeezes the swing arm 73, the swing arm 73 and the side shaft 72 swing synchronously, and the torsion spring deforms. When the bottom block 74 moves away from the swing arm 73, the swing arm 73 and the side shaft 72 swing in opposite directions under the action of the torsion spring. Therefore, the swing arm 73 can swing left and right, which can stir the waste liquid and neutralizing agent on both sides of the round shaft 50, promote the mixing and purification of the two, expand the mixing and purification range, enhance the purification effect, and improve the purification efficiency.

[0035] During the rotation of the circular shaft 50, the transverse block 51 reciprocates laterally, driving the bearing block 60 to reciprocate laterally. The bearing block 60 then drives the side block 64 to move synchronously, causing the side block 64 to move laterally within the linkage groove 68. During the rotation of the circular shaft 50, the circular shaft 50 also drives the second cylindrical cam 63 to rotate. The second cylindrical cam 63 drives the linkage block 67 to reciprocate vertically via the second curved groove, the second auxiliary block 65, and the lifting block 66. The linkage block 67 drives the bearing block 60 to reciprocate vertically via the linkage groove 68 and the side block 64. The bearing block 60 drives the bristle layer 62 to reciprocate vertically, thereby enabling the bristle layer 62 to pass vertically through the filter screen 23. This allows the bristle layer 62 to pass through the filter screen 23, lifting up debris on the filter screen 23 and turning it over, thus preventing debris from blocking or clogging the filter screen 23. Furthermore, the bristles passing through the filter screen 23 also clean the filter screen 23, preventing it from becoming clogged.

[0036] After the waste liquid is purified, rotate the door panel 12 to make the inside of the treatment box 10 open to the outside; then remove the sealing block 21 to allow the purified waste liquid in the inner box 20 to be discharged.
