Description

It is mainly used in sewage treatment plants, water plants and water treatment fields where drugs need to be added. The drug dissolving device is generally a parallel three-tank type with a rectangular shape; each tank is equipped with a group of multiple stirring motors for driving, and there is a drug powder silo adding part on the top. The drug powder is fed into the silo and flows into the three tanks in turn with water, and is stirred and mixed to achieve drug maturation and dissolution.

[0003] Each tank of the existing drug dissolving device is equipped with multiple groups of stirring motors for driving. Multiple motors work together. The stirring intensity is high during stirring, and the liquid collides with the tank wall, which is easy to produce loud noise. At the same time, the drug powder silo is equipped with a vibration arch breaker, which needs to continuously generate vibration noise during operation, and the on-site environment is poor; in addition, when the drug powder is not stirred sufficiently, it will form undissolved hard agglomerates and deposit at the bottom of each tank, which will increase the dosage of the drug and reduce the efficiency. It is also easy to cause the drug adding pump, filter, safety valve, one-way valve, valve and other components to become blocked and fail, resulting in the collapse of the water pipeline, which requires regular maintenance.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0030] As Figures 1 - 3 shown, in one embodiment, an automatic medicine dissolving device includes:

[0031] A dissolution tank 1, on the upper part of which a storage and feeding assembly 2 and a driving and stirring assembly 3 are installed, on the top of one side of which a water inlet pipeline assembly 4 is installed, on the bottom of one side of which an output pipeline assembly 5 is installed, and in front of which an electrical control assembly 6 is arranged.

[0032] As Figures 1 - 3 shown, in this embodiment, the dissolution tank 1 includes a rigid base 108, and on the upper end surface of the base 108, a concentric external cylinder 111 and an internal cylinder 112 are connected. The external cylinder 111 is square or circular, and the internal cylinder 112 is circular.

[0033] Further, an inner cylinder partition 113 with water passing holes is installed in the inner cylinder body 112, and the inner cylinder body 112 is separated into a dissolution chamber 105, a ripening chamber 106, and a liquid storage chamber 104 by the inner cylinder partition 113. Among them, one side of the top of the inner cylinder body 112 forms a wetting chamber 101 through a wetting chamber wall 115. The dissolution chamber 105 is arranged at the top of the inner cylinder body 112, the ripening chamber 106 is arranged at the bottom of the inner cylinder body 112, the liquid storage chamber 104 is arranged on one side of the inner cylinder body 112, and an overflow channel 107 is also arranged in the inner cylinder body 112, connecting the ripening chamber 106 and the liquid storage chamber 104 through the overflow channel 107. After the powder enters the wetting chamber 101, it is dissolved in sequence and then enters the ripening chamber 106, and finally the well-ripened medicament solution overflows into the liquid storage chamber 104 for storage and standby.

[0034] Please continue to refer to Figure 2 , a dissolution tank cover 102 is connected to the top end of the outer cylinder body 111. The upper part of the dissolution tank cover 102 is connected to the wetting chamber wall 115. The wetting chamber wall 115 is in an inverted conical shape to enclose the wetting chamber 101, and a water inlet is connected to the outer tangent direction of the wetting chamber wall 115.

[0035] Further, a liquid level sensor 109 for external output and a water inlet liquid level sensor 110 are installed at the bottom of one side of the outer cylinder body 111, and a high liquid level sensor 114 is installed at the top of one side of the outer cylinder body 111. During the production process of the liquid material, a detection signal is output to the electrical control component 6, and then a control signal is sent to automatically control the overall equipment. The overall structure of the four chambers is relatively compact, effectively improving the space utilization rate, significantly reducing the floor area, and saving one-third of the floor area compared with the traditional medicine dissolving device under the same amount of medicament preparation.

[0036] As Figures 1 - 3 shown, in this embodiment, the storage and feeding component 2 includes a medicine powder bin 202, a variable-speed screw driving motor 201, a feeding screw 203, and a arch-breaking gear 204, which are used for storing and feeding medicine powder.

[0037] Among them, the medicine powder bin 202 is installed on one side of the top of the dissolution tank cover 102. A variable-speed screw driving motor 201 is installed on one side of the medicine powder bin 202. The variable-speed screw driving motor 201 is connected to the feeding screw 203 inside the medicine powder bin 202. An arch-breaking gear 204 is fixed above the feeding screw 203 through a gear shaft 205, and the arch-breaking gear 204 meshes with the spiral surface of the feeding screw 203. During use, the electrical control component 6 controls the variable-speed screw driving motor 201 to drive the feeding screw 203 to rotate, so that the spiral surface on the feeding screw 203 pushes the arch-breaking gear 204 to rotate on the gear shaft 205, and continuously supplies the medicine powder to the outlet.

[0038] Further, a low-level sensor 206 is also installed in the middle of the medicine powder silo 202 to monitor the remaining material state during the feeding process; a constant-temperature heater 207 is installed at the bottom outlet of the medicine powder silo 202 to perform constant-temperature heating on the medicine during the feeding process, effectively increasing the material temperature and facilitating the rapid dissolution and drying of the medicine.

[0039] As Figures 1 - 3 shown, in this embodiment, the driving and stirring assembly 3 includes a stirring drive motor 301 and multiple groups of stirring paddles. The stirring paddles include a dissolving inclined-blade stirring paddle 305, a dissolving flat stirring paddle 304, and a ripening stirring paddle 303. The assembly is used for stirring the liquid medicine.

[0040] Further, sound insulation cotton 103 is provided inside the dissolving tank cover 102. The stirring drive motor 301 is installed on the top of the dissolving tank cover 102, and the axis of the stirring drive motor 301 is eccentric to the inner cylinder 112. The stirring shaft 302 passes through the top of the dissolving tank cover 102 and is connected to the stirring drive motor 301. The dissolving inclined-blade stirring paddle 305 and the dissolving flat stirring paddle 304 are fixed in the dissolving cavity 105 through the stirring shaft 302, and the ripening stirring paddle 303 is fixed in the ripening cavity 106 through the stirring shaft 302. Among them, the ripening stirring paddles 303 can be symmetrically distributed in two groups or multiple groups evenly, and the form can be a flat paddle or an inclined-blade paddle. Since the sound insulation cotton 103 is provided inside the dissolving tank cover 102, isolation and shock absorption can be carried out, and the noise generated by the liquid colliding with the tank wall during the high-intensity stirring, mixing, and dissolving of the medicine powder in the inner cylinder 112 can be effectively reduced.

[0041] As Figures 1 - 3 shown, in this embodiment, the water inlet pipe assembly 4 includes a water inlet pipe 406. The water inlet pipe 406 is connected to an external water source through a water inlet pipe connection flange 401. The water inlet pipe 406 is successively connected with a pressure regulating valve 402, a solenoid valve 403, a flow meter 404, and a water shortage induction sensor 405. The outlet of the water inlet pipe 406 is communicated with the water inlet connected to the outer tangent direction of the infiltration cavity wall 115; the output pipe assembly 5 includes an output water pipe 503. The output water pipe 503 is communicated with the ripening cavity 106. The output pipeline is connected to an external output source through an output pipeline connection flange 501. A valve 502 is provided on the output water pipe 503.

[0042] As Figures 1 - 3 shown, in this embodiment, an electrical control assembly 6 is also installed on the side of the outer cylinder 111. After receiving the signals of detection components such as the external output liquid level sensor 109, the water inlet liquid level sensor 110, the high liquid level sensor 114, the low-level sensor 206, and the water shortage induction sensor 405, it issues control signals to perform logical sequence control on corresponding actuators such as the variable-speed screw drive motor 201, the stirring drive motor 301, the solenoid valve 403, and the constant-temperature heater 207 to meet the automatic operation and output relevant signals.

[0043] Working principle:

[0044] Determine the mixing concentration and preparation amount of the solution, calculate the required powder feeding speed and water inlet speed, adjust the speed control parameters of the variable-speed screw driving motor 201, and measure the powder feeding speed; set the required speed control parameters through the electrical control component 6, at the same time adjust the water inlet pressure of the pressure regulating valve 402, and read the water inlet speed displayed by the flow meter 404 to set the required water inlet speed;

[0045] After completing the above preset conditions, add an appropriate amount of powder that meets the shift operation into the interior of the powder bin 202. The electrical control component 6 sends a control signal to start the operation of the actuators such as the variable-speed screw driving motor 201, the stirring driving motor 301, and the constant-temperature heater 207. After the solenoid valve 403 is opened, water enters the wetting cavity 101 in sequence through the pressure regulating valve 402, the solenoid valve 403, the flow meter 404, the water shortage induction sensor 405, etc.; since the water inlet direction of the water inlet is the tangent direction of the outer circle of the wetting cavity wall 115, the pressurized water flow will rotate along the wetting cavity wall 115, and then form a vortex water curtain on the conical surface of the wetting cavity wall 115.

[0046] Driven by the variable-speed screw driving motor 201, the feeding screw 203 rotates to push the medicament through the outlet constant-temperature heater 207 to heat the medicament to an appropriate dissolution temperature (50 - 60 °C), and then the medicament is added. The medicament is evenly scattered into the wetting cavity 101 and falls onto the surface of the vortex water curtain. It is fully wetted and evenly mixed by the rotation of the vortex water curtain, so that the water penetrates and slips into the interior of the medicament particles and flows into the dissolution cavity 105 by its own weight, preventing the hardening of undissolved dry powder; at the same time, the spiral surface on the feeding screw 203 pushes the arch-breaking gear 204 to rotate on the gear shaft 205, disturbing the medicament accumulated inside the powder bin 202, effectively preventing the formation of the arching phenomenon of the medicament, and enabling the medicament to be stably and reliably continuously added to the wetting cavity 101.

[0047] The medicament vortex water curtain rotates to fully wet the uniform liquid medicine mixture, which will flow into the dissolution chamber 105 and the ripening chamber 106 under its own weight. The stirring shaft 302 is driven by the stirring drive motor 301 to drive the dissolution flat stirring paddle 304, the dissolution inclined blade stirring paddle 305 and the ripening stirring paddle 303 to rotate. In the dissolution chamber 105, the flat stirring paddle generates laminar flow, and the dissolution inclined blade stirring paddle 305 makes the liquid generate convection. Since the axis of the stirring drive motor 301 is eccentric to the inner cylinder 112, turbulence pulsation can be generated inside, and then the fully wetted and uniform liquid medicine mixture is forcibly stirred and diffused, so that the medicament particles gradually disperse across the newly formed wetting interface, and the medicament molecular chains quickly unfold, which can effectively improve the mixing uniformity and dissolution efficiency. Then it flows into the ripening chamber 106 under its own weight; the ripening stirring paddle 303 can make the liquid in the chamber generate stable laminar flow or convection, pulling the molecular chains of the medicament to diffuse until they are completely unfolded, so that the liquid medicine is completely ripened.

[0048] As the liquid level in the inner cylinder 112 continues to rise, the fully ripened liquid medicine overflows the ripened and dissolved medicament solution through the overflow channel 107 on the inner cylinder 112 into the liquid storage chamber 104 for storage and standby.

[0049] (1) When the liquid level of the dissolved and ripened medicament solution stored in the liquid storage chamber 104 reaches the high liquid level sensor 114, the variable speed screw drive motor 201 stops running. Subsequently, the feeding screw 203 stops adding medicament, the solenoid valve 403 closes to stop water inlet, and the continuous dissolution of the medicament automatically stops preparation; the output pipeline assembly 5 at the bottom of the liquid storage chamber 104 is connected to an external dosing pump to extract and use the dissolved and ripened medicament solution in the liquid storage chamber 104. When the liquid level in the liquid storage chamber 104 drops to the medicament water inlet liquid level sensor 110, the medicament water inlet liquid level sensor 110 sends a signal, and the solenoid valve 403 is automatically opened through the electrical control assembly 6, and the variable speed screw drive motor 201 is started to run, and the feeding screw 203 starts to add medicament, forming a cycle of continuous medicament preparation process.

[0050] (2) When the solenoid valve 403 is opened and the external water pressure is lower than the set water inlet pressure of the pressure regulating valve 402, the pressure regulating valve 402 automatically closes, and the water shortage induction sensor 405 sends a signal, generating an audible and visual alarm signal for water shortage failure through the electrical control assembly 6 to prompt relevant personnel for maintenance or repair; at the same time, the variable speed screw drive motor 201 stops running, the feeding screw 203 stops adding medicament, the solenoid valve 403 closes, and the continuous dissolution of the medicament in this device automatically stops preparation.

[0051] (3) When the liquid level of the dissolved and ripened medicament solution stored in the liquid storage chamber 104 is lower than the medicament external output liquid level sensor, the external output liquid level sensor sends a signal of the lack of ripened liquid medicine, and provides a stop signal for the external dosing equipment through the electrical control assembly 6 to protect the relevant dosing equipment.

[0052] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
