Water treatment agent mixing apparatus

Abstract

This utility model relates to the field of water treatment agent mixing technology and discloses a water treatment agent mixing device, including a mixing cylinder. Support frames are fixedly installed on both sides of the mixing cylinder. A servo motor drives a telescopic connecting shaft and a T-shaped rotating shaft to rotate synchronously. The ball in the ball socket on the side of the T-shaped rotating shaft rolls along an annular guide rail inclined on the inner wall of the sleeve. Under the guidance of the inclined trajectory of the annular guide rail, the linkage of the T-shaped rotating shaft drives the telescopic connecting shaft to extend and retract adaptively. This allows the stirring shaft and stirring rod connected to the bottom of the T-shaped rotating shaft to achieve up-and-down reciprocating motion while rotating and stirring. This allows the stirring rod to cover different height areas inside the mixing cylinder, effectively breaking the stirring dead corners that are easily formed inside the mixing cylinder. This ensures that the components of the water treatment agent can fully contact and mix quickly in both the vertical and horizontal directions, without needing to extend the stirring time to achieve a uniform mixing effect, significantly improving the mixing efficiency and quality of the water treatment agent.

Description

Technical Field

[0001] This utility model relates to the field of water treatment agent mixing technology, and in particular to a water treatment agent mixing device. Background Technology

[0002] In the water treatment industry, water treatment agents are core functional agents that ensure water purification, water quality stability, and water recycling. These agents encompass various categories, including flocculants, corrosion inhibitors, scale inhibitors, bactericides, and adsorbents. Their applications have expanded from municipal sewage treatment and industrial wastewater treatment to drinking water purification and aquaculture water body control. The mixing process before adding water treatment agents to the water body plays a crucial role in ensuring the uniform dispersion of all components, improving the reaction rate between the agent and the water, preventing excessively high local concentrations that could lead to waste or secondary pollution, and ensuring the stability of the water treatment effect.

[0003] In the daily preparation and use of water treatment agents, mixing operations need to be adjusted according to requirements such as agent formulation, differences in water quality, and treatment scale to ensure that the mixed agents achieve the preset uniformity standard. Currently, the water treatment agent mixing equipment commonly used in the industry is mostly a fixed stirring structure, that is, a stirring shaft driven by a motor drives stirring blades to rotate inside the mixing drum, and the mixing of agents is achieved by the shearing and pushing action of the blades.

[0004] However, this type of fixed stirring equipment has a single stirring trajectory, and the stirring blades can only rotate around a fixed axis. This makes it easy for some areas inside the mixing drum to form dead zones, making it difficult for the agents to fully contact and mix evenly. The mixing efficiency is low. For water treatment agents with high viscosity or that are prone to agglomeration, it is often necessary to extend the stirring time to achieve the basic mixing requirements. This not only increases energy consumption but also makes it difficult to meet the mixing requirements of efficient and high-quality water treatment agents. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water treatment agent mixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water treatment agent mixing device, comprising a mixing cylinder, support frames fixedly installed on both sides of the mixing cylinder, a servo motor installed in the middle of the support frame, the output end of the servo motor passing through the support frame and fixedly installed with a telescopic connecting shaft, a T-shaped rotating shaft fixedly installed at the other end of the telescopic connecting shaft, a sleeve sleeved on the outer side of the T-shaped rotating shaft, a stirring shaft provided at the bottom of the T-shaped rotating shaft, and multiple stirring rods uniformly fixedly installed on the surface of the stirring shaft; The sleeve has an annular guide rail inside, which is inclined at an angle to the inner wall of the sleeve. A ball socket is fixedly installed on the side of the T-shaped rotating shaft. A ball is placed inside the ball socket, and an embedding groove adapted to the ball is opened inside the ball socket. The ball rolls in the embedding groove. The side of the ball away from the ball socket is connected to the inside of the annular guide rail. Two columns are fixedly installed inside the mixing cylinder. The two columns are located on both sides of the stirring shaft, and multiple baffles are fixedly installed on the surface of the two columns.

[0007] Preferably, each of the four corners of the sleeve is provided with a fixing screw, and the other end of the fixing screw is threaded into the inside of the support base. The sleeve can be detachably installed on the side of the support frame away from the servo motor by means of the fixing screw.

[0008] Preferably, a locking block is fixedly installed on one end of the stirring shaft near the T-shaped rotating shaft, and a through hole is provided on the side of the locking block.

[0009] Preferably, the T-shaped rotating shaft has a fitting groove adapted to the locking block on the side near the stirring shaft, and a through hole is provided on one end of the T-shaped rotating shaft.

[0010] Preferably, the interior of the second through hole is connected to the interior of the fitting groove, and the stirring shaft is installed inside the fitting groove by means of a locking block.

[0011] Preferably, mounting bolts are provided inside the first and second through holes, and the threaded end of the mounting bolts extends to the outside of the second through hole and is threadedly connected to the nut.

[0012] Preferably, a discharge pipe is fixedly installed on the side of the mixing cylinder, the inner end of the discharge pipe is connected to the inside of the mixing cylinder, and a control valve is installed in the middle of the discharge pipe.

[0013] Preferably, the gap between the T-shaped rotating shaft and the inner wall of the sleeve is filled with lubricating material, and the groove inside the ball socket and the mating surface of the ball are filled with lubricating material of the same material, which is lithium-based grease.

[0014] In summary, this utility model has the following beneficial effects: 1. This utility model uses a servo motor to drive the telescopic connecting shaft and the T-shaped rotating shaft to rotate synchronously. The ball in the ball socket on the side of the T-shaped rotating shaft rolls along the annular guide rail that is inclined on the inner wall of the sleeve. Under the guidance of the inclined trajectory of the annular guide rail, the T-shaped rotating shaft is linked to drive the telescopic connecting shaft to extend and retract adaptively. This allows the stirring shaft and stirring rod connected to the bottom of the T-shaped rotating shaft to achieve up-and-down reciprocating motion while rotating and stirring. This allows the stirring rod to cover different height areas inside the mixing drum, effectively breaking the stirring dead corners that are easily formed inside the mixing drum. This ensures that the components of the water treatment agent can fully contact and mix quickly in both the vertical and horizontal directions. It eliminates the need to extend the stirring time to achieve a uniform mixing effect, significantly improving the mixing efficiency and mixing quality of the water treatment agent. 2. During the rotation and reciprocating motion of the stirring shaft, the stirring rods on the surface of the stirring shaft shear and push the water treatment agent in the mixing cylinder. At the same time, the baffles on the surfaces of the columns on both sides inside the mixing cylinder can block and divert the flow of the water treatment agent, disrupting the original single flow direction of the water treatment agent and promoting the formation of complex convection circulation. This further enhances the dispersion effect of each component of the agent, avoids the problem of uneven mixing caused by local agglomeration of the agent, and ensures that water treatment agents with different formulations and different viscosities can all reach the preset uniformity standard. 3. This utility model provides a ball socket seat on the side of the T-shaped rotating shaft. The ball inside the ball socket seat rolls with the annular guide rail on the inner wall of the sleeve. The fit clearance between the T-shaped rotating shaft and the inner wall of the sleeve, as well as the fit surface between the ball socket seat and the ball, are all filled with lithium-based grease. By replacing the traditional sliding fit with the rolling of the ball, the coefficient of motion friction between the T-shaped rotating shaft and the sleeve is significantly reduced, reducing wear and tear between components. At the same time, it extends the service life of transmission components such as the T-shaped rotating shaft, sleeve, and ball, ensuring the long-term stable operation of the mixing equipment.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example: Reference Figures 1-5 A water treatment agent mixing device includes a mixing cylinder 1, with support frames 3 fixedly installed on both sides of the mixing cylinder 1. A servo motor 301 is installed in the middle of the support frame 3. The output end of the servo motor 301 passes through the support frame 3 and is fixedly installed with a telescopic connecting shaft 303. A T-shaped rotating shaft 302 is fixedly installed at the other end of the telescopic connecting shaft 303. A sleeve 5 is sleeved on the outside of the T-shaped rotating shaft 302. A stirring shaft 4 is provided at the bottom of the T-shaped rotating shaft 302. Multiple stirring rods 401 are uniformly fixedly installed on the surface of the stirring shaft 4. The sleeve 5 has an annular guide rail 501 inside, which is inclined at an angle to the inner wall of the sleeve 5. A ball socket seat 6 is fixedly installed on the side of the T-shaped rotating shaft 302. A ball 601 is provided inside the ball socket seat 6. An embedding groove adapted to the ball 601 is provided inside the ball socket seat 6. The ball 601 is rolled in the embedding groove. The side of the ball 601 away from the ball socket seat 6 is connected to the inside of the annular guide rail 501. Two columns 9 are fixedly installed inside the mixing cylinder 1. The two columns 9 are located on both sides of the stirring shaft 4. Multiple baffle rods 901 are fixedly installed on the surface of the two columns 9.

[0019] Specifically: In actual use, the output end of the servo motor 301 passes through the support frame 3 and is fixedly connected to the telescopic connecting shaft 303, which can directly transmit rotational power to the telescopic connecting shaft 303, directly driving the telescopic connecting shaft 303 to rotate, ensuring the power supply for mixed operations. One end of the telescopic connecting shaft 303 is fixed to the output end of the servo motor 301, and the other end is connected to the T-shaped rotating shaft 302. It can adaptively extend and retract according to the axial movement requirements of the T-shaped rotating shaft 302, ensuring continuous power transmission without hindering the up and down movement of the T-shaped rotating shaft 302. The T-shaped rotating shaft 302 receives the rotational power transmitted by the telescopic connecting shaft 303, driving the bottom stirring shaft 4 to rotate synchronously. On the other hand, the ball socket 6 fixed on its side provides a mounting space for the ball 601 on the moving carrier. The embedded groove inside the ball socket 6 can limit the displacement of the ball 601, ensuring that the ball 601 always maintains stable rolling contact with the annular guide rail 501 on the inner wall of the sleeve 5, and preventing the ball 601 from leaving the track and affecting the motion transmission.

[0020] The sleeve 5 is fitted on the outside of the T-shaped rotating shaft 302. The annular guide rail 501 inside provides a movement trajectory for the ball 601. The annular guide rail 501 is set at an inclined angle. When the ball 601 rotates with the T-shaped rotating shaft 302 and rolls along the annular guide rail 501, the inclined structure of the annular guide rail 501 will generate an axial guiding force on the ball 601. This guiding force is transmitted to the T-shaped rotating shaft 302 through the ball socket 6, causing the T-shaped rotating shaft 302 to drive the telescopic connecting shaft 303 to perform axial extension and retraction, thereby realizing the up and down reciprocating motion of the stirring shaft 4.

[0021] The stirring shaft 4 is connected to the T-shaped rotating shaft 302 and can rotate and reciprocate up and down synchronously with the T-shaped rotating shaft 302. Multiple stirring rods 401, which are uniformly fixed on its surface, directly contact the water treatment agent in the mixing cylinder 1. Through the combined motion of rotational shearing and reciprocating pushing, the water treatment agent is mixed in multiple dimensions, expanding the stirring coverage area and reducing mixing dead zones. The two columns 9 fixed inside the mixing cylinder 1 are located on both sides of the stirring shaft 4. Multiple turbulence rods 901 fixed on the surface of the columns 9 can block and divert the agent when the stirring rods 401 drive the water treatment agent to flow, breaking the single flow direction of the agent and promoting the formation of complex convection circulation, further improving the uniformity of the agent mixing.

[0022] It should be noted that the telescopic connecting shaft 303 consists of two telescopic columns. The two columns have mutually compatible guide keys and keyways inside. The guide key is fixed to the outer wall of the inner column, and the keyway is opened on the inner wall of the outer column. The guide key extends along the axial direction of the column. When the two columns extend or retract relative to each other along the axial direction, the guide key is always engaged in the keyway, which can effectively limit the circumferential displacement of the two columns and prevent relative rotation between the two columns. This ensures that the telescopic connecting shaft 303 can stably transmit torque to the T-shaped rotating shaft 302 when transmitting the rotational power of the servo motor 301.

[0023] The sleeve 5 is provided with a fixing screw 502 through each of the four corners of its end. The other end of the fixing screw 502 is threaded into the support base. The sleeve 5 can be detached and installed on the side of the support frame 3 away from the servo motor 301 by fixing screw 502. The fixing screw 502 can be used to disassemble the sleeve 5 on the support frame 3, which is convenient for regular maintenance of the annular guide rail 501 inside the sleeve 5. A locking block 7 is fixedly installed on one end of the stirring shaft 4 near the T-shaped rotating shaft 302. A through hole 702 is opened through the side of the locking block 7. A matching groove 701 that matches the locking block 7 is opened on the side of the T-shaped rotating shaft 302 near the stirring shaft 4. A through hole 703 is opened through the side of one end of the T-shaped rotating shaft 302. The interior of the through hole 703 is connected to the interior of the matching groove 701. The stirring shaft 4 is inserted and installed in the interior of the matching groove 701 through the locking block 7. A mounting bolt 8 is provided inside the through hole 702 and the through hole 703. The threaded end of the mounting bolt 8 extends to the outside of the through hole 703 and is threadedly connected to the nut. Specifically: In actual use, the locking block 7 fixed at the end of the stirring shaft 4 is adapted to the fitting groove 701 opened on the T-shaped rotating shaft 302. It can quickly position and install the stirring shaft 4 to the bottom of the T-shaped rotating shaft 302 by plugging it in, avoiding circumferential offset during installation and ensuring that the two rotate synchronously in subsequent movements. The through hole 702 through the side of the locking block 7 and the through hole 703 through the side of the T-shaped rotating shaft 302 cooperate with each other. When the locking block 7 is fully inserted into the fitting groove 701, the axis of the through hole 702 and the through hole 703 will automatically align, providing a passage for the mounting bolt 8. Through the threaded connection of the bolt and nut, the locking block 7 is firmly fixed in the fitting groove 701, thereby realizing a stable connection between the stirring shaft 4 and the T-shaped rotating shaft 302, preventing loosening or separation during rotation and reciprocating motion, and ensuring the stability of power transmission.

[0024] When the stirring shaft 4 needs to be replaced or maintained, the operator only needs to unscrew the nut on the outside of the mounting bolt 8, and then pull the mounting bolt 8 out from the inside of the through hole 702 and the through hole 703 to release the fixed constraint between the locking block 7 and the mating groove 701; then the stirring shaft 4 can be pulled out directly along the axial direction of the mating groove 701 to complete the disassembly of the old stirring shaft 4. The entire disassembly process does not require disassembling other core components of the equipment, nor does it require the use of complicated special tools.

[0025] When installing the new stirring shaft 4, simply insert the locking block 7 at the end of the new stirring shaft 4 into the mating groove 701 of the T-shaped rotating shaft 302. The fitting structure between the locking block 7 and the mating groove 701 enables quick positioning. At this time, the through hole 1 702 on the locking block 7 and the through hole 2 703 on the T-shaped rotating shaft 302 will automatically align. After passing the mounting bolt 8 through the through hole 1 702 and the through hole 2 703, screw the nut on the end of the bolt and tighten it to complete the installation and fixing of the new stirring shaft 4.

[0026] A discharge pipe 2 is fixedly installed on the side of the mixing cylinder 1. The inner end of the discharge pipe 2 is connected to the inside of the mixing cylinder 1. A control valve 201 is installed in the middle of the discharge pipe 2. The discharge pipe 2 can quickly discharge the uniformly mixed water treatment agent from the equipment, preventing the agent from remaining in the mixing cylinder 1. The control valve 201 installed in the middle of the discharge pipe 2 can directly control the opening and closing of the discharge pipe 2 through opening and closing operations. The operator can flexibly adjust the valve opening and closing status and degree of opening and closing according to the mixing progress of the water treatment agent and the actual discharge requirements. The fitting gap between the T-shaped rotating shaft 302 and the inner wall of the sleeve 5 is filled with lubricating material. The lithium-based grease filled in the fitting gap between the T-shaped rotating shaft 302 and the inner wall of the sleeve 5 can provide lubrication between the two parts. When the components move relative to each other, a lubricating film is formed, which greatly reduces the frictional resistance between the T-shaped rotating shaft 302 and the inner wall of the sleeve 5 during rotation and axial extension, and reduces mechanical wear between components. The embedded groove inside the ball socket 6 and the mating surface of the ball 601 are filled with a lubricating material of the same material, which is lithium-based grease. The lithium-based grease can lubricate the ball 601 when it rolls along the embedded groove and the annular guide rail 501, reduce the frictional loss between the ball 601 and the embedded groove and the annular guide rail 501, ensure that the ball 601 rolls flexibly, and thus ensure that the T-shaped rotating shaft 302 can stably bear the guiding force of the annular guide rail 501.

[0027] The working principle of this utility model is as follows: In specific use, the water treatment agent to be mixed is first put into the mixing cylinder 1 according to the preset ratio. Then, the servo motor 301 installed in the middle of the support frame 3 is started. The output end of the servo motor 301 transmits power to the telescopic connecting shaft 303, which drives the telescopic connecting shaft 303 and the T-shaped rotating shaft 302 fixed at the end to rotate synchronously. The stirring shaft 4 connected to the bottom of the T-shaped rotating shaft 302 through the insertion and engagement of the locking block 7 and the fitting groove 701, as well as the fastening action of the mounting bolt 8, will rotate synchronously with the T-shaped rotating shaft 302, so that the multiple stirring rods 401 on the surface of the stirring shaft 4 will perform preliminary rotation and stirring of the water treatment agent in the mixing cylinder 1.

[0028] During the rotation of the T-shaped rotating shaft 302, the ball socket 6 fixed on its side rotates together. The ball 601 embedded in the groove inside the ball socket 6 maintains rolling contact with the inclined annular guide rail 501 opened on the inner wall of the sleeve 5. Since the annular guide rail 501 is set at an inclined angle, the ball 601 will be guided by the inclined trajectory when it rolls along the annular guide rail 501, and the force will be transmitted to the T-shaped rotating shaft 302 through the ball socket 6, causing the T-shaped rotating shaft 302 to drive the telescopic connecting shaft 303 to expand and contract axially. During this process, the stirring shaft 4 will simultaneously realize up and down reciprocating motion while rotating with the T-shaped rotating shaft 302, thereby driving the stirring rod 401 to increase the vertical motion trajectory on the basis of rotational stirring, and expanding the stirring coverage area.

[0029] At the same time, when the stirring rod 401 drives the water treatment agent to flow, the turbulence rod 901 will block and divert the flowing water treatment agent, disrupting the single flow direction of the agent and causing the agent to form convection. After the water treatment agent is mixed to the preset uniformity, the servo motor 301 is turned off and the control valve 201 in the middle of the discharge pipe 2 is opened, so that the mixed water treatment agent can be discharged from the discharge pipe 2.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
