Description

Technical Field

[0001] The present invention belongs to the technical field of pharmaceutical formulation, and specifically refers to a pharmaceutical formulation device for desulfurized wastewater treatment. Background Art

[0002] Desulfurized wastewater is the wastewater generated during the limestone wet flue gas desulfurization process. Since the impurities contained in the wastewater mainly include suspended solids, supersaturated sulfites, sulfates, and heavy metals and other harmful substances, in order to avoid environmental pollution, the wastewater needs to be treated, and certain chemical agents need to be added during the treatment process. Since the wastewater contains many components, during use, it is necessary to perform targeted formulation of various pharmaceutical components according to the water quality conditions.

[0003] At present, the existing pharmaceutical formulation devices for desulfurized wastewater treatment have the following problems:

[0004] The existing pharmaceutical formulation devices for desulfurized wastewater treatment do not have the ability to regulate the reaction pressure of the liquid medicine during the formulation process, resulting in the inability to timely discharge the bubbles generated inside the liquid medicine during the mixing reaction, and the inability to enhance the contact strength between the liquid medicine molecules. Moreover, the traditional pharmaceutical formulation devices for desulfurized wastewater treatment also do not have the ability to further grind the precipitated drug particles, thereby affecting the full fusion of the liquid medicine during the formulation, and thus reducing the formulation efficiency of the pharmaceutical agents. Therefore, it cannot meet the current usage requirements of the pharmaceutical formulation devices for desulfurized wastewater treatment. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, this solution provides a pharmaceutical formulation device for desulfurized wastewater treatment that can regulate the reaction pressure of the liquid medicine during the formulation process and can further grind the precipitated drug particles.

[0006] The technical solution adopted by this solution is as follows: A pharmaceutical formulation device for desulfurized wastewater treatment proposed by this solution includes a base, a medicine preparation rack, a pressing and mixing mechanism, a buffer-type exhaust mechanism, and a series-type liquid discharge mechanism. The medicine preparation rack is arranged on the upper wall of the base. The pressing and mixing mechanism includes a driving mechanism, a liquid pressing mechanism, and a rolling mechanism. The driving mechanism is arranged at both ends of the medicine preparation rack. The liquid pressing mechanism is arranged on the upper wall of the medicine preparation rack. The rolling mechanism is arranged inside the liquid pressing mechanism. The buffer-type exhaust mechanism includes a pressure reducing mechanism and a gas filtering mechanism. The pressure reducing mechanism is arranged on one side of the liquid pressing mechanism. The gas filtering mechanism is arranged on the side of the medicine preparation rack away from the pressure reducing mechanism. The series-type liquid discharge mechanism is arranged inside the base wall.

[0007] As a further optimization of the solution in this case, the driving mechanism includes a driving motor, a driving gear, a transmission groove, a driving frame, a driven gear, a gear transmission belt and a driving shaft. The driving motors are symmetrically arranged on the inner walls at both ends of the medicine dispensing rack. The driving gear is arranged at the power end of the driving motor. The transmission grooves are symmetrically arranged on the upper walls at both ends of the medicine dispensing rack, and the transmission grooves are arranged in a through manner. The driving frames are symmetrically arranged on the upper walls at both ends of the medicine dispensing rack. The driving shaft is rotatably arranged between the driving frames. The driven gears are symmetrically arranged at both ends of the driving shaft, and the driven gears are arranged vertically with the transmission grooves. The gear transmission belt passes through the transmission grooves and is wound between the driving gear and the driven gears. The driving gear and the driven gears are respectively engaged with the gear transmission belt. The liquid pressing mechanism includes a liquid pressing cam, a return spring, an arc-shaped panel, a liquid pressing rod, a liquid pressing plate, a medicine dispensing cylinder, a transparent cover and a medicine dispensing valve. Multiple groups of the liquid pressing cams are arranged on the outer side of the driving shaft. The return spring is arranged on the upper wall of the medicine dispensing rack below the liquid pressing cam. The arc-shaped panel is arranged on the side of the return spring away from the medicine dispensing rack, and the return spring is in an extended state. The medicine dispensing cylinder is arranged through the inner wall of the medicine dispensing rack inside the return spring, and the medicine dispensing cylinder is arranged in a through manner. The transparent cover is communicated and arranged on the bottom wall of the medicine dispensing cylinder. The liquid pressing plate is slidably arranged on the inner wall of the medicine dispensing cylinder. The liquid pressing rod is arranged between the arc-shaped panel and the liquid pressing plate. The medicine dispensing valve is communicated and arranged on the side wall of the medicine dispensing cylinder. The rolling mechanism includes a groove, a rolling rod, a rolling ball, a rolling spring and mixing blades. The groove is arranged between the liquid pressing rod and the liquid pressing plate, and the groove is open at the lower end. The rolling rod is slidably arranged on the inner wall of the groove. The rolling ball is arranged on the bottom wall of the rolling rod. The rolling spring is arranged between the inner wall of the groove and the rolling rod. Multiple groups of the mixing blades are arranged on the outer side of the rolling rod.

[0008] During use, in the initial state, the liquid pressing cam does not contact the arc-shaped panel. The return spring drives the arc-shaped panel to rise through deformation, opening the medicine dispensing valve. The medicine dispensing valve is conducted with the medicine dispensing cylinder. The required liquid medicine for mixing reaction is filled into the medicine dispensing cylinder through the medicine dispensing valve. The driving motor drives the driving gear to rotate through the power end. The driving gear drives the driven gear to rotate through the gear transmission belt. The driven gear drives the liquid pressing cam to rotate through the driving shaft. When the liquid pressing cam rotates, it presses down on the arc-shaped panel. The protruding end of the liquid pressing cam is arranged at an acute angle with the surface of the arc-shaped panel. The return spring deforms and shortens, and the depth of the liquid pressing plate entering the medicine dispensing cylinder increases. When the liquid level of the liquid medicine fits the bottom wall of the liquid pressing plate, the filling of the liquid medicine into the medicine dispensing cylinder stops, and the medicine dispensing valve is closed. The driving motor drives the liquid pressing cam to rotate through the driving gear, the gear transmission belt, the driven gear and the driving shaft. The protruding part of the liquid pressing cam continuously presses down on the arc-shaped panel. The arc-shaped panel drives the liquid pressing plate through the liquid pressing rod to continuously pump and press the liquid medicine inside the medicine dispensing cylinder, ensuring the full reaction of the liquid medicine inside the medicine dispensing cylinder.

[0009] Preferably, the pressure reducing mechanism includes a telescopic tube, a buffer tube and a pressure relief valve. The telescopic tube is disposed through the inner wall of the liquid pressing plate. The buffer tube is disposed through the medicine dispensing cylinder and communicated with one end of the telescopic tube away from the liquid pressing plate. The pressure relief valve is communicated with one side of the buffer tube away from the telescopic tube. The air filtering mechanism includes a filtering frame, a filtering cylinder, a water-absorbing cotton layer, an exhaust joint, an activated carbon adsorption layer and a filtering tube. The filtering frame is disposed on one side of the medicine dispensing frame away from the buffer tube. A plurality of groups of the filtering cylinders are disposed through the inner wall of one end of the filtering frame away from the medicine dispensing frame. The activated carbon adsorption layer is disposed on the inner wall of the filtering cylinder. The exhaust joint is communicated with one side of the filtering cylinder away from the medicine dispensing frame. The water-absorbing cotton layer is disposed on the inner wall of one end of the filtering cylinder close to the exhaust joint. The filtering tube is communicated between one end of the pressure relief valve away from the buffer tube and one side of the filtering cylinder away from the exhaust joint.

[0010] During use, when the protruding end of the liquid pressing cam driven by the drive shaft is perpendicular to the upper surface of the arc-shaped panel, the liquid pressing rod drives the liquid pressing plate to press down the liquid medicine, and the internal pressure of the liquid medicine increases. Part of the liquid medicine enters the buffer tube through the telescopic tube under the extrusion force, reducing the extrusion strength on the medicine dispensing cylinder. When the liquid medicine is extruded, the pressure inside it will increase, and the change in the increased pressure will change the interaction between the reactant molecules, increasing the collision frequency and collision force between the molecules, thereby accelerating the reaction rate of the liquid medicine inside the medicine dispensing cylinder. When the protruding end of the liquid pressing cam driven by the drive shaft moves away from the upper surface of the arc-shaped panel, the reset spring elastically resets to drive the arc-shaped panel to rise. The arc-shaped panel drives the liquid pressing plate to slide up along the inner wall of the medicine dispensing cylinder through the liquid pressing rod. Part of the gas inside the buffer tube enters the medicine dispensing cylinder through the telescopic tube, reducing the load pressure borne by the medicine dispensing cylinder. Under the suction of the liquid pressing plate, a negative pressure state is formed above the liquid level of the liquid medicine, and the bubbles contained in the liquid medicine are more likely to escape from the liquid medicine at low pressure, thereby ensuring the full reaction between the liquid medicine molecules.

[0011] Specifically, the series-type liquid discharging mechanism includes a liquid discharging tube and a liquid discharging valve. The liquid discharging tube is disposed through the inner wall of the base, and the liquid discharging valve is disposed through the base and communicated between the transparent cover and the liquid discharging tube.

[0012] During use, when the reaction of the liquid medicine inside the medicine dispensing cylinder is completed, the liquid discharging valve is opened, the liquid discharging tube is communicated with the medicine dispensing cylinder, and the proportioned medicine inside the medicine dispensing cylinder is discharged through the liquid discharging tube.

[0013] Wherein, a controller is disposed on the upper wall of the base.

[0014] Preferably, the controller is electrically connected to the drive motor.

[0015] The beneficial effects obtained by adopting the above structure are as follows:

[0016] Compared with the prior art, the present solution adopts a combination of a cam structure and an elastic structure. Through the provided ramming and mixing mechanism, buffer-type exhaust mechanism, and series-type liquid discharge mechanism, and with the coordinated use of the drive mechanism, liquid pressing mechanism, rolling mechanism, pressure reducing mechanism, and air filtering mechanism, the continuous rotation of the liquid pressing cam driven by the drive shaft enables continuous pumping and pressing operations on the liquid medicine inside the medicine dispensing cylinder. On the one hand, the negative pressure effect is utilized to accelerate the escape of the bubbles generated inside during the liquid medicine mixing reaction, reduce the occurrence of adverse reactions in the liquid medicine, and ensure the effectiveness of the proportioned medicine. On the other hand, through the extrusion operation on the liquid medicine during the proportioning process, the contact opportunity and collision frequency between molecules are increased, the reaction rate of the liquid medicine is accelerated, and the liquid medicine can be better mixed. The drive motor drives the liquid pressing cam to rotate through the driving gear, gear transmission belt, driven gear, and drive shaft. The protruding part of the liquid pressing cam continuously presses down on the arc-shaped panel, and the arc-shaped panel drives the liquid pressing plate through the liquid pressing rod to continuously pump and press the liquid medicine inside the medicine dispensing cylinder, ensuring the full reaction of the liquid medicine inside the medicine dispensing cylinder.

[0037] The series type liquid discharging mechanism 35 includes a liquid discharging pipe 36 and a liquid discharging valve 37. The liquid discharging pipe 36 is disposed through the inner wall of the base 1. The liquid discharging valve 37 is disposed through the base 1 and communicated between the transparent cover 18 and the liquid discharging pipe 36.

[0038] A controller 38 is disposed on the upper wall of the base 1.

[0039] The controller 38 is electrically connected to the driving motor 5.

[0040] During specific use, the liquid pressing cam 12 does not contact the arc-shaped panel 14 in the initial state, the liquid discharging valve 37 is in a closed state, the reset spring 13 drives the arc-shaped panel 14 to rise through deformation, the controller 38 controls the driving motor 5 to start, the driving motor 5 drives the driving gear 6 to rotate through the power end, the driving gear 6 drives the driven gear 9 to rotate through the gear transmission belt 10, the driven gear 9 drives the liquid pressing cam 12 to rotate through the driving shaft 40, the liquid pressing cam 12 presses down on the arc-shaped panel 14 during rotation, the protruding end of the liquid pressing cam 12 is arranged at an acute angle with the surface of the arc-shaped panel 14, the reset spring 13 deforms and shortens, and the depth of the liquid pressing plate 16 entering the medicine dispensing cylinder 17 increases;

[0041] Open the dispensing valve 42. The dispensing valve 42 is communicated with the dispensing cylinder 17, and the liquid medicine required for mixing reaction is filled into the interior of the dispensing cylinder 17 through the dispensing valve 42. When the liquid level of the liquid medicine fits against the bottom wall of the liquid pressing plate 16, stop filling the liquid medicine into the interior of the dispensing cylinder 17, close the dispensing valve 42, and the controller 38 controls the driving motor 5 to start. The driving motor 5 drives the liquid pressing cam 12 to rotate through the driving gear 6, the gear transmission belt 10, the driven gear 9 and the driving shaft 40. The protruding part of the liquid pressing cam 12 continuously presses down on the arc-shaped panel 14, and the arc-shaped panel 14 drives the liquid pressing plate 16 through the liquid pressing rod 15 to continuously pump and press the liquid medicine inside the dispensing cylinder 17, ensuring the full reaction of the liquid medicine inside the dispensing cylinder 17;

[0042] Preset the pressure relief threshold of the pressure relief valve 29. When the pressure inside the buffer tube 28 reaches the pressure relief threshold of the pressure relief valve 29, the pressure relief valve 29 is conducted, and the air bubbles inside the pumped-out liquid medicine enter the interior of the filter cylinder 32 through the buffer tube 28 and the filter tube 41. The gas is filtered through the activated carbon adsorption layer 39 and the water-absorbing cotton layer 33 and then discharged through the exhaust joint 34;

[0043] When the driving shaft 40 drives the protruding end of the liquid pressing cam 12 away from the upper surface of the arc-shaped panel 14, the return spring 13 elastically returns to drive the arc-shaped panel 14 to rise. The arc-shaped panel 14 drives the liquid pressing plate 16 to slide up along the inner wall of the dispensing cylinder 17 through the liquid pressing rod 15. At this time, the distance between the bottom wall of the liquid pressing plate 16 and the liquid level of the liquid medicine is such that under the suction of the liquid pressing plate 16, a negative pressure state is formed above the liquid level of the liquid medicine, and the air bubbles contained in the liquid medicine are easily released from the liquid medicine at low pressure, thus ensuring the full reaction between the liquid medicine molecules;

[0044] When the driving shaft 40 drives the protruding end of the liquid pressing cam 12 to be perpendicular to the upper surface of the arc-shaped panel 14, the liquid pressing rod 15 drives the liquid pressing plate 16 to press down the liquid medicine, and the gas pumped out from the liquid medicine and part of the liquid medicine enter the interior of the buffer tube 28 under the extrusion force through the telescopic tube 27, reducing the extrusion strength borne by the dispensing cylinder 17. The increase in the pressure inside the dispensing cylinder 17 helps to change the interaction between the reactant molecules, increase the collision frequency and collision force between the molecules, and thus accelerate the reaction rate of the liquid medicine inside the dispensing cylinder 17;

[0045] When the driving shaft 40 drives the protruding end of the liquid pressing cam 12 away from the upper surface of the arc-shaped panel 14 again, the liquid pressing plate 16 rises, the liquid medicine inside the buffer tube 28 flows back into the interior of the dispensing cylinder 17 through the telescopic tube 27, and the gas inside the buffer tube 28 is inhaled into the interior of the dispensing cylinder 17 through the telescopic tube 27, reducing the load pressure borne by the dispensing cylinder 17;

[0046] Some of the particulate matter in the liquid medicine precipitates on the bottom wall of the transparent cover 18 and does not fully react. When the protruding end of the liquid pressing cam 12 rotates perpendicular to the upper surface of the arc-shaped panel 14, the liquid pressing plate 16 drives the rolling rod 21 to descend through the rolling spring 23. The rolling spring 23 is set to be elongated. The rolling rod 21 drives the rolling ball 22 to fit with the bottom wall of the transparent cover 18 by using the deformation of the rolling spring 23, and grinds the granular medicine precipitated on the bottom wall of the transparent cover 18. When the rolling rod 21 moves up and down with the liquid pressing plate 16, it drives the mixing blades 24 to stir the liquid medicine inside the medicine dispensing cylinder 17 up and down, promoting the reaction between the granular medicine and the liquid medicine;

[0047] Observe the quantity of the precipitated medicine through the transparent cover 18. When the precipitate disappears and the reaction with the liquid medicine inside the medicine dispensing cylinder 17 is completed, manually open the pressure relief valve 29. The outside air enters the inside of the filter cylinder 32 through the exhaust joint 34. After being filtered by the water absorption cotton layer 33, the outside air enters the inside of the medicine dispensing cylinder 17. Open the liquid discharge valve 37, and the liquid discharge pipe 36 is communicated with the medicine dispensing cylinder 17. The prepared medicine inside the medicine dispensing cylinder 17 is discharged through the liquid discharge pipe 36; Just repeat the above operations for the next use.
