Description

Technical Field

[0001] This invention relates to the field of pharmaceutical mixing equipment, and in particular to a pharmaceutical mixing device for wastewater treatment. Background Technology

[0002] In modern wastewater treatment engineering, three methods are generally used: physical methods, biological methods and chemical methods. Chemical methods use chemical reactions to treat or recover dissolved or colloidal substances in wastewater. This is done by adding chemicals to the wastewater. Before use, the chemicals need to be mixed and proportioned manually or by equipment.

[0003] When using existing mixing devices, the mixing of solid particles and liquid agents is mostly done manually, which not only increases the labor intensity of the operators, but also poses certain safety hazards when handling some corrosive drugs.

[0004] Chinese patent document CN215822567U discloses a mixing and stirring device for wastewater treatment agents, relating to the field of wastewater treatment agent processing technology. It solves the technical problem that existing agent mixing devices only use stirring blades on a single rotating shaft for unidirectional stirring, thus reducing the working efficiency of the mixing device and the yield of the mixed agent. The device includes a mixing tank, with an inlet pipe fixedly installed on the side wall of the mixing tank, an inlet hopper fixedly installed on the inlet pipe, and an outlet pipe fixedly installed on the lower wall of the mixing tank, with a solenoid valve fixedly installed on the outlet pipe. The device described in the above document uses a planetary stirring section in a bidirectional stirring device, allowing the spiral stirring rod to rotate and revolve simultaneously to mix the agent. A flipping stirring section laterally flips the agent, thereby achieving mixing and stirring of the agent in different directions, resulting in more thorough mixing, improved working efficiency of the mixing and stirring device, and increased yield of the mixed agent.

[0005] However, in actual use, it is still unable to process solid drug particles independently, and the mixing effect is not good by relying solely on the spiral stirring blades. Large solid particles cannot be quickly integrated into the reagent, and the mixing and reaction rate is slow. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention uses a stirring-driven structure, a dynamic mixing structure, and a grinding structure to grind and pulverize the solid drug fed into the feeder and then feed it into the inner cavity of the mixing tank to mix with the liquid drug fed into the liquid inlet pipe. The grinding structure can make the drug particles finer and improve the dissolution rate. Under the action of the mixing structure, the drug is quickly dissolved in the drug, improving the efficiency and effect of drug mixing.

[0020] 2. The present invention utilizes curved slides one and two inside the mixing tank to allow the driven shaft to rotate under the action of the drive shaft. The limiting shaft slides up and down within curved slides one and two, causing the driven shaft to swing up and down. This, in turn, causes the aeration structure to swing up and down, resulting in the churning of the reagents inside the mixing tank. Compared with the traditional vortex stirring method, the dissolution efficiency is higher, which can improve the contact efficiency between the reagents and reactants, improve the mixing effect, and shorten the reaction time.

[0021] 3. In this invention, the driven shaft rotates while driving the aeration structure to rotate. At the same time, the gas supplied by the air inlet pipe is sent into the agent inside the mixing tank through the aeration holes via the rotating fan blades. This allows the part of the agent at the bottom center that cannot contact the air to come into contact with the air through a number of generated fine bubbles, thereby enhancing the easy reaction rate. At the same time, due to the airflow, the agent at the bottom will be driven to move upward, increasing the mixing and reaction rate by improving fluidity. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, a wastewater treatment agent mixing device includes a feeder 1. The lower end of the feeder 1 is fixedly connected to the front of the upper end of the mixing tank 2. A mixing drive structure 7 is fixedly connected to the rear of the upper end of the mixing tank 2. A mixing structure 8 is provided at the lower end of the mixing drive structure 7 and the inner cavity of the mixing tank 2. A grinding structure 9 is provided on the upper part of the inner surface of the mixing tank 2 and the upper part of the outer surface of the mixing structure 8.

[0035] In wastewater treatment, chemical agents often need to be mixed in multiple ways, including the mixing of solid and liquid agents. However, most existing equipment mixes solid agents by directly pouring them into liquid solutions and then stirring. For some large-particle agents, this not only results in low dissolution efficiency but also causes a lot of waste. If manual handling is required, the splashing debris and dust also pose a certain danger.

[0036] The aforementioned feeder 1 is a device that can feed solid drugs intermittently and quantitatively. It can feed solid drugs into the inner cavity of the mixing tank 2 through the feed port at the top of the mixing tank 2. This feeding device is used in various modern production industries and is a mature technology. Its operating principle and structure will not be described in detail in this invention.

[0037] An air inlet pipe 6 is provided on the inner surface of the hybrid drive structure 7 and the inner side of the hybrid structure 8. The end of the air inlet pipe 6 away from the mixing tank 2 is connected to an air supply device. Air is continuously supplied to the inside of the mixing tank 2 through equipment such as an air pump and a blower. This invention only provides air to the inside through the air inlet pipe 6. The specific air supply method is connected according to the actual situation of the use site and is not described in this invention.

[0038] A liquid inlet pipe 3 is fixedly connected to the front of the outer surface of the mixing tank 2. An observation window 4 is opened at the lower part of the front of the outer surface of the mixing tank 2. A liquid outlet pipe 5, which communicates with the bottom wall of the inner cavity of the mixing tank 2, is fixedly connected to the lower front of the mixing tank 2. The liquid inlet pipe 3 is used to deliver liquid reagents, and the liquid outlet pipe 5 is mainly used to remove the mixed reagents. Both of the above structures are equipped with valve structures to control the flow of liquids. These are the inlet and outlet channels required by conventional mixing equipment and are basic configurations in existing mixing equipment. They will not be described further in this invention.

[0039] In this embodiment, the liquid medicine is fed into the bottom of the inner cavity of the mixing tank 2 through the liquid inlet pipe 3. At the same time, the feeder 1 feeds the grinding structure 9 inside the mixing tank 2. The mixing drive structure 7 drives the mixing structure 8 and the grinding structure 9 to rotate. The medicine is fed into the bottom of the inner cavity of the mixing tank 2 through the grinding structure 9 and mixed and stirred by the mixing structure 8. At the same time, the stirring of the medicine by the air inlet pipe 6 in cooperation with the mixing structure 8 increases the contact rate between the liquid medicine and the medicine, thereby improving the mixing efficiency of the medicine.

[0040] Specifically, to provide power for the operation of hybrid structure 8, see [link to relevant documentation]. Figure 2 The hybrid drive structure 7 includes a drive motor 73. The bottom end of the drive motor 73 is fixedly connected to the upper rear part of the mixing barrel 2. A bevel gear 72 is fixedly connected to the outer surface of the output end of the drive motor 73. A bevel gear 71 meshes with the lower part of the outer surface of the bevel gear 72. A drive shaft 74 is fixedly connected to the inner surface of the bevel gear 71. The bottom end of the bevel gear 71 and the outer surface of the drive shaft 74 are rotatably connected to a bracket that is fixedly connected to the upper end of the mixing barrel 2. A tension spring 75 is fixedly connected to the lower end of the drive shaft 74. The end of the tension spring 75 away from the drive shaft 74 is fixedly connected to the hybrid structure 8.

[0041] When the drive motor 73 rotates, it drives the second bevel gear 72 and the first bevel gear 71 to rotate, thereby driving the drive shaft 74, which is fixed together with the second bevel gear 72, to rotate. The drive shaft 74 provides power to the mixing structure 8 and realizes the basic function of stirring.

[0042] Furthermore, to achieve mixing of the internal reagents, see [reference needed]. Figure 2 and Figure 3The mixing structure 8 includes a driven shaft 81, and a number of stirring blades 82 are fixedly connected in a ring at the middle of the outer surface of the driven shaft 81. A groove 812 adapted to the drive shaft 74 is opened at the upper end of the driven shaft 81. The inner surface of the groove 812 is slidably connected to the lower part of the outer surface of the drive shaft 74. The bottom wall of the inner cavity of the groove 812 is fixedly connected to the lower end of the tension spring 75.

[0043] The main function of the chute 812 is to limit the drive shaft 74 on the annular path, so that when the drive shaft 74 rotates, it can drive the driven shaft 81 to rotate synchronously. The stirring blade 82 fixed on the outer surface of the driven shaft 81 also rotates in the agent to stir the agent. At the same time, the connection between the two by the chute 812 can also prevent the transmission from being affected when the driven shaft 81 moves up and down.

[0044] Example 2

[0045] Based on Example 1, this embodiment uses the interaction between the mixing structure 8 and the curved slide 22 inside the mixing tank 2. During the rotation and stirring process, the mixing structure 8 undulates up and down under the action of the curved slide 22, which causes the stirring blades 82 to churn the stirred medicine, allowing the drug particles put into the mixing tank 2 to mix better with the medicine and improve the mixing efficiency.

[0046] Specifically, for the undulating effect that occurs in the hybrid structure 8 during movement, please refer to... Figure 5 and Figure 6 The mixing barrel 2 has a through hole 21 at the middle of its upper end, which communicates with the inner cavity. The upper part of the inner surface of the through hole 21 is provided with a curved slide 22 in an annular pattern. The inner surface of the mixing barrel 2 located on the upper part of the grinding structure 9 is provided with a curved slide 23 in an annular pattern. Both the curved slide 23 and the curved slide 22 are wavy curves with the same undulation trajectory and undulation stroke. The left and right parts of the outer surface of the driven shaft 81 are fixedly connected to the limiting shaft 811. The left and right parts of the outer surface of the limiting shaft 811 are slidably connected to the inner surface of the curved slide 22.

[0047] The aforementioned curved slide 1 22 and curved slide 2 23 are two wavy curves with the same undulation curve and the same height difference between the top and bottom, but different stroke radii. During operation, the curved slide 1 22 drives the limit shaft 811 to move up and down, which in turn causes the driven shaft 81 to move up and down to a certain extent. The stirring blade 82, which is fixed together with the driven shaft 81, stirs in the agent, thereby agitating the solvent in the middle of the mixing tank 2, causing the solvent to surge, so that the drug particles can be fully mixed with the agent in the upper layer, thereby improving the mixing efficiency.

[0048] Example 3

[0049] Based on Example 2, this embodiment utilizes the combination of the limiting component 91, the grinding drive component 92, and the grinding roller 93 to grind and pulverize solid drugs on the screen 94. This process grinds large-volume solid drugs into fine particles, which then pass through the mesh of the screen 94 into the drug within the mixing tank 2. The fine powder increases the contact area between the drugs, thereby improving the dissolution rate of the solid drugs.

[0050] Specifically, to achieve the grinding and pulverization of the solid medicine fed into feeder 1, refer to... Figure 2 , Figure 4 and Figure 7 The grinding structure 9 includes a limiting component 91. The inner side of the limiting component 91 is fixedly connected to the middle of the top wall of the inner surface of the mixing barrel 2. A grinding drive component 92 is provided at the lower end of the limiting component 91. A grinding roller 93 is fixedly connected to the side of the grinding drive component 92 near the inner wall of the mixing barrel 2. The end of the grinding roller 93 away from the grinding drive component 92 is slidably connected to the inner surface of the curved slide rail 23. A screen 94 is fixedly connected to the upper part of the inner surface of the mixing barrel 2. The inner surface of the screen 94 is rotatably connected to the middle of the outer surface of the driven shaft 81.

[0051] The screen 94 has several mesh openings. When the drug particles are larger than the mesh size, they will stay on the upper part of the screen 94. When the grinding structure 9 rotates with the mixing structure 8, the drug will be processed to the appropriate size before passing through these mesh openings into the medicine in the mixing tank 2.

[0052] Furthermore, in order to achieve both the rotational function of the grinding structure 9 and the hybrid structure 8 while simultaneously following their revolution around the sun, the grinding drive component 92 needs to be limited. (See [reference needed]). Figure 4 The limiting component 91 includes a fixing ring 911. The upper end of the fixing ring 911 is fixedly connected to the middle of the top wall of the inner cavity of the mixing tank 2. The inner side of the fixing ring 911 is slidably connected to the outer surface of the driven shaft 81. Several limiting rods 912 are fixedly connected to the bottom of the fixing ring 911 in a ring array. The lower part of the outer surface of the limiting rods 912 is jointly provided with a grinding drive component 92. The inner surface of the fixing ring 911 is slidably connected to the upper part of the outer surface of the driven shaft 81.

[0053] Furthermore, for grinding and pulverizing solid drugs, see [reference needed]. Figure 7 The grinding drive assembly 92 includes a T-shaped sliding seat 921 and two meshing bevel gears 923. Several limiting rods 912 extend through the upper end of the T-shaped sliding seat 921 to the lower end of the T-shaped sliding seat 921 and are slidably connected to the T-shaped sliding seat 921.

[0054] Since the fixed ring 911 is fixed to the top wall of the inner cavity of the mixing tank 2, when the driven shaft 81 rotates, it will not transmit power to the fixed ring 911. Similarly, the several limiting rods 912 fixed together with the fixed ring 911 will not respond to the driven shaft 81, thereby limiting the T-shaped sliding seat 921 in the circumferential direction, so that the T-shaped sliding seat 921 can only slide up and down on the outer surface of the driven shaft 81 and will not rotate with the driven shaft 81.

[0055] The lower part of the vertical outer surface of the T-shaped sliding seat 921 is fixedly connected to the inner surface of the bevel gear 923 in the horizontal direction. The lower part of the vertical outer surface of the T-shaped sliding seat 921 is rotatably connected to a concave bracket 922. The vertical part of the inner surface of the concave bracket 922 is rotatably connected to the bevel gear 923 located in the vertical direction.

[0056] One end of the concave bracket 922 is fixedly connected to the outer surface of the driven shaft 81 in the vertical direction. When the driven shaft 81 rotates, the concave bracket 922 drives the vertical bevel gear 923 to rotate as well. However, since the horizontal bevel gear 923 is fixed together with the T-shaped sliding seat 921, the T-shaped sliding seat 921 will not rotate due to the action of the limiting rod 912. Therefore, the horizontal bevel gear 923 is in a stationary state. Since the two bevel gears 923 mesh with each other, the horizontal bevel gear 923 will rotate when it rotates around the driven shaft 81 under the action of the driven shaft 81.

[0057] The end of the vertically oriented bevel gear 923 near the concave bracket 922 extends through the inner surface of the concave bracket 922 to the outer surface of the concave bracket 922 and is fixedly connected to the end of the grinding roller 93 away from the inner wall of the mixing tank 2. The inner surface of the T-shaped sliding seat 921 is slidably connected to the upper part of the outer surface of the driven shaft 81. The end of the concave bracket 922 away from the T-shaped sliding seat 921 is fixedly connected to the outer surface of the driven shaft 81 through a connecting groove.

[0058] When the vertical bevel gear 923 rotates, it drives the grinding roller 93, which is fixed to it, to rotate around the driven shaft 81. At the same time, the grinding roller 93 also undulates under the drive of the driven shaft 81 and the curved slide rail 23, alternately hammering, rolling and grinding the drug particles on the surface of the screen 94, thereby crushing the drug particles into particles of appropriate size. The particles then enter the medicine in the inner cavity of the mixing tank 2 through the screen 94. The processed small drug particles dissolve faster than large drug particles, which can reduce the time required for dissolution and improve the efficiency of drug mixing. At the same time, using the grinding structure 9 to process the drug can also reduce the workflow of the operators, eliminating the need for manual or other equipment for crushing, which also improves the efficiency of operation.

[0059] Example 4

[0060] Based on Example 3, this embodiment introduces a large number of air bubbles into the mixing tank 2 by combining the air inlet pipe 6 and the aeration structure 83, thereby enhancing the tumbling effect of the agent, increasing the reaction rate of each substance in the agent, and improving the mixing effect.

[0061] Specifically, to achieve the function of filling the interior of the drug with gas to cause it to churn, see [reference needed]. Figure 7 and Figure 8 An aeration structure 83 is provided at the lower end of the driven shaft 81. The aeration structure 83 includes a rotating seat 831. A sliding groove 832 is provided at the upper end of the rotating seat 831. The lower end of the rotating seat 831 is rotatably connected to the bottom wall of the inner cavity of the mixing tank 2.

[0062] The function of the aeration structure 83 is to drive the solvent at the bottom upward by surging bubbles, so that the solvent can be evenly mixed in the upper and lower areas, avoiding the impact of solid drug deposition at the bottom on the mixing effect; at the same time, aeration can also increase the reaction rate of each substance in the solvent. Some chemicals are more active and react faster with the addition of air, which can enhance the mixing effect, shorten the reaction time, and relatively improve the mixing efficiency.

[0063] When the driven shaft 81 rotates, the aeration structure 83 will rotate as a whole due to the action of the second chute 832. At the same time, due to the presence of the second chute 832, the aeration structure 83 will not move up and down when the driven shaft 81 moves up and down, so that the aeration structure 83 is always at the bottom of the mixing tank 2.

[0064] A number of rotating fan blades 833 are fixedly connected to the outer surface of the rotating seat 831 in a ring. The upper end of each of the rotating fan blades 833 is provided with a number of aeration holes 834 that communicate with the inner cavity of the rotating fan blades 833. A check valve 835 is fixedly connected to the inner surface of each of the aeration holes 834. Each of the check valves 835 is a downward-opening trumpet-shaped rubber membrane.

[0065] Since the aeration structure 83 is entirely inside the agent, in order to prevent the agent from entering the aeration structure 83 and flowing back through the air inlet pipe 6, a check valve 835 is installed on the inner side of each aeration hole 834. The aeration hole 834 is small in size, and through the tension of the agent itself and the function of the check valve 835, the agent can be prevented from entering, and the waste of the agent is also reduced.

[0066] Furthermore, to provide an air intake passage for the aeration structure 83, see [reference needed]. Figure 1 , Figure 7 and Figure 8The air intake pipe 6 passes through the upper end of the drive shaft 74 and the bottom wall of the inner cavity of the first slide groove 812 and extends to the inner cavity of the aeration structure 83. The air intake pipe 6 passes through the lower end of the driven shaft 81 and communicates with the inner cavity of the second slide groove 832. The inner surface of the second slide groove 832 is slidably connected to the lower part of the outer surface of the driven shaft 81. Several rotating fan blades 833 are hollow inside and communicate with the inner cavity of the second slide groove 832 through air holes.

[0067] Air is introduced into the aeration structure 83 through the air inlet pipe 6. When the rotating fan blade 833 rotates under the action of the driven shaft 81, it will stir the bottom agent and blow fine air into the bottom of the agent through the aeration hole 834. The agent at the bottom will be stirred up by the rotation of the rotating fan blade 833 and the airflow blown out of the aeration hole 834, which will further improve the reaction rate of each substance in the agent and improve the mixing effect.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
