Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to a chemical mixing device for wastewater treatment ponds. Background Technology
[0002] Pharmaceutical mixing equipment is used in the pharmaceutical industry to mix powdered or paste-like materials to ensure uniform mixing of different materials without causing dissolution, volatilization, or deterioration of the materials during the mixing process.
[0003] When pharmaceutical mixing chambers mix drugs, some substances adhere to the inner walls of the chamber, accumulating a large amount of dirt over time, which can affect the efficacy of the prepared drugs. Therefore, it is necessary to clean the inner walls of the mixing chamber regularly. However, because the mixing chamber has a stirring device inside, other tools are needed for cleaning, making the process rather troublesome. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a chemical mixing device for wastewater treatment ponds, thereby solving the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A chemical mixing device for a wastewater treatment tank includes a mixing tank, an internal stirring rod, a driving device mounted on the top of the stirring rod, and a mixing mechanism connected to the outer wall of the stirring rod.
[0009] The hybrid mechanism includes:
[0010] A baffle rod is attached to the outer wall of the stirring rod;
[0011] A cleaning mechanism is provided at one end of the baffle rod near the inner wall of the mixing tank. The cleaning mechanism includes:
[0012] A centrifugal block is hinged to the end of a baffle rod, and a cleaning rod is connected to one end of the centrifugal block near the inner wall of the mixing tank.
[0013] When the stirring rod rotates under the drive of the driving device, it generates centrifugal force, causing the centrifugal block to stick to the inner wall of the mixing tank, so that the cleaning rod on the centrifugal block can scrape the inner wall of the mixing tank.
[0014] One end of the turbulence rod is rotatably connected to one end of the stirring rod. The turbulence rod can rotate under the drive of the driving component so that the centrifugal block sweeps on the inner wall of the mixing tank.
[0015] The cleaning rod on the outside of the centrifuge block scrapes against the inner wall of the mixing chamber, thus cleaning the inner wall of the mixing chamber. In order to avoid scratching the inner wall of the mixing chamber, the cleaning rod on the outside of the centrifuge block does not contact the inner wall of the mixing chamber when the inertial force generated by the rotation of the stirring rod is insufficient to throw the centrifuge block out.
[0016] Preferably, a spiral blade is connected to the upper part of the stirring rod, the spiral blade fills the space in the middle of the mixing box, and there is a gap between the spiral blade and the inner wall of the mixing box;
[0017] The stirring rod drives the spiral blade to rotate. The thrust generated by the rotation of the spiral blade can drive the liquid inside the mixing tank to move downward or upward, and then flow back through the gap between the spiral blade and the mixing tank, thus creating circulation. This helps to transport the medicine that has just been added to the top of the mixing tank to the bottom of the mixing tank, and at the same time, it can turn the medicine at the bottom of the mixing tank upward to prevent sedimentation.
[0018] Preferably, the outer wall of the stirring rod is provided with a rotating sleeve, one end of the turbulence rod is rotatably connected to the inner wall of the rotating sleeve, and a torsion spring is connected between the turbulence rod and the inner wall of the rotating sleeve, so that the turbulence rod can rotate within a certain angle.
[0019] Preferably, a movable sleeve is provided in the middle of the spoiler rod, the movable sleeve is freely rotatable with the middle of the spoiler rod, and a thin rod is connected to the outer wall of the movable sleeve.
[0020] Preferably, the end of the turbulence rod near the centrifugal block has a hinge groove, and one end of the centrifugal block is hinged to the inner wall of the hinge groove. A first elastic element is also connected between one end of the centrifugal block and the inner wall of the hinge groove. The default state of the first elastic element is a contracted state, in which the centrifugal block can be brought close to the turbulence rod. When the turbulence rod rotates at low speed, the centrifugal force generated cannot overcome the elastic force of the first elastic element, and the centrifugal block cannot be thrown out. When the turbulence rod rotates at high speed, the centrifugal force generated can overcome the elastic force of the first elastic element, and the centrifugal block is thrown out, so that the cleaning rod on the outer wall of the centrifugal block can abut against the inner wall of the mixing tank, thereby achieving the cleaning effect on the inner wall of the mixing tank.
[0021] Preferably, a cleaning block is provided above the rotation path of the centrifugal block, and a cleaning bristle is connected to the bottom of the cleaning block. The bottom of the cleaning bristle can be inserted into the gap of the cleaning rod, and the dirt in the middle of the cleaning rod can be cleaned by the cleaning bristle.
[0022] Preferably, the cleaning block is elastically connected to the inner wall of the mixing box, one end of the cleaning block is connected to a slider, the inner wall of the mixing box is provided with a groove, and a second elastic element is connected between the slider and the inner wall of the groove.
[0023] Preferably, one end of the turbulence rod is connected to a first meshing wheel, and the inner wall of the mixing tank is connected to a first meshing ring. The first meshing ring is intermittently arranged, and the first meshing wheel meshes with the first meshing ring. When the turbulence rod revolves around the stirring rod, under the action of the first meshing wheel and the first meshing ring, the turbulence rod rotates around its own central axis.
[0024] Preferably, one end of the movable sleeve is connected to a second meshing wheel, and a second meshing ring is provided below the first meshing wheel. The second meshing wheel meshes with the second meshing ring. When the turbulence rod revolves around the stirring rod, the movable sleeve rotates under the action of the second meshing wheel and the second meshing ring.
[0025] Compared with the prior art, the present invention provides a chemical mixing device for sewage treatment ponds, which has the following beneficial effects:
[0026] 1. The present invention cleans the inner wall of the mixing chamber by scraping the cleaning rod on the outside of the centrifuge block against the inner wall of the mixing chamber. In order to prevent scratches from forming on the inner wall of the mixing chamber, the cleaning rod on the outside of the centrifuge block does not contact the inner wall of the mixing chamber when the inertial force generated by the rotation of the stirring rod is insufficient to throw the centrifuge block out. Therefore, the mixing chamber can be protected when it is not being cleaned.
[0027] 2. This invention uses a stirring rod to drive a spiral blade to rotate. The thrust generated by the rotation of the spiral blade can drive the liquid inside the mixing tank to move downwards or upwards, and then flow back through the gap between the spiral blade and the mixing tank, thus creating a circulation. This is beneficial for transporting the medicine just added to the top of the mixing tank to the bottom of the mixing tank, and at the same time, it can also turn the medicine at the bottom of the mixing tank upwards to prevent sedimentation.
[0028] 3. When the baffle rod rotates, due to the presence of the drag-increasing shield, the baffle rod will rotate in one direction while revolving around the sun and maintain this angle. When the first meshing wheel at the end of the baffle rod engages with the first meshing ring, the baffle rod will rotate in another direction under the meshing action. In summary, the baffle rod can rotate back and forth in two directions, thereby allowing the centrifugal blocks to sweep on the inner wall of the mixing tank and increasing the cleaning area.
[0029] 4. In this invention, because the turbulence rod can rotate, the angle of the centrifuge block can be changed, so that the centrifuge block can intersect the horizontal line at certain times. Then, the cleaning rod on the outer wall of the centrifuge block is washed by the impact force of the liquid, thereby keeping the cleaning block clean and ensuring the cleaning effect on the cleaning rod.

Detailed Implementation
[0040] Example:
[0041] See Figure 1-3 A chemical mixing device for a wastewater treatment tank includes a mixing tank 100, a feed inlet 110 at the top of the mixing tank 100, a stirring rod 120 inside the mixing tank 100, a drive device 130 mounted on the top of the stirring rod 120, and a mixing mechanism 200 connected to the outer wall of the stirring rod 120.
[0042] The mixing mechanism 200 includes:
[0043] A turbulence-dispersing rod 220 is connected to the outer wall of the stirring rod 120;
[0044] A cleaning mechanism 300 is provided at one end of the baffle rod 220 near the inner wall of the mixing tank 100. The cleaning mechanism 300 includes:
[0045] Centrifugal block 310 is hinged to the end of baffle rod 220, and a cleaning rod 320 is connected to one end of centrifugal block 310 near the inner wall of mixing tank 100;
[0046] When the stirring rod 120 rotates under the drive of the driving device 130, it generates centrifugal force, causing the centrifugal block 310 to stick to the inner wall of the mixing tank 100, so that the cleaning rod 320 on the centrifugal block 310 scrapes the inner wall of the mixing tank 100.
[0047] It should be noted that the aforementioned drive device 130 can be a stepper motor or a servo motor.
[0048] One end of the turbulence rod 220 is rotatably connected to one end of the stirring rod 120. The turbulence rod 220 can rotate under the drive of the driving component so that the centrifugal block 310 sweeps on the inner wall of the mixing tank 100.
[0049] The cleaning rod 320 on the outside of the centrifuge block 310 scrapes against the inner wall of the mixing tank 100, thereby cleaning the inner wall of the mixing tank 100. In order to prevent scratches from forming on the inner wall of the mixing tank 100, the cleaning rod 320 on the outside of the centrifuge block 310 does not contact the inner wall of the mixing tank 100 when the inertial force generated by the rotation of the stirring rod 120 is insufficient to throw the centrifuge block 310 out.
[0050] like Figure 1 , Figure 2 As shown, in one possible embodiment, the upper part of the stirring rod 120 is connected to a spiral blade 140, the spiral blade 140 fills the space in the middle of the mixing tank 100, and there is a gap between the spiral blade 140 and the inner wall of the mixing tank 100.
[0051] The stirring rod 120 drives the spiral blade 140 to rotate. The thrust generated by the rotation of the spiral blade 140 can drive the liquid inside the mixing tank 100 to move downward or upward, and then flow back from the gap between the spiral blade 140 and the mixing tank 100, thus creating circulation. This is beneficial for transporting the medicine just added to the top of the mixing tank 100 to the bottom of the mixing tank 100, and at the same time, it can also turn the medicine at the bottom of the mixing tank 100 upward to prevent sedimentation.
[0052] Continue reading Figure 4The outer wall of the stirring rod 120 is provided with a rotating sleeve 211. One end of the turbulence rod 220 is rotatably connected to the inner wall of the rotating sleeve 211. A torsion spring 212 is connected between the turbulence rod 220 and the inner wall of the rotating sleeve 211, allowing the turbulence rod 220 to rotate within a certain angle. The rotating sleeve 211 is connected to the fixing member 210, and the fixing member 210 is fixed to the stirring rod 120.
[0053] like Figure 3 , Figure 4 As shown, in one possible embodiment, a movable sleeve 240 is provided in the middle of the spoiler 220, the movable sleeve 240 is freely rotatable with the middle of the spoiler 220, and a thin rod 250 is connected to the outer wall of the movable sleeve 240;
[0054] The movable sleeve 240 drives the thin rod 250 to rotate, thereby ensuring that the medicine inside the mixing box 100 is fully mixed.
[0055] Continue reading Figure 5 As one possible embodiment, the baffle rod 220 has a hinge groove 330 at one end near the centrifugal block 310. One end of the centrifugal block 310 is hinged to the inner wall of the hinge groove 330. A first elastic element 340 is also connected between one end of the centrifugal block 310 and the inner wall of the hinge groove 330. The first elastic element 340 can be a spring or an elastic sheet. The first elastic element 340 is in a contracted state by default. In this state, the centrifugal block 310 can be brought close to the baffle rod 220. When the baffle rod 220 rotates at low speed, the centrifugal force generated cannot overcome the elastic force of the first elastic element 340, and the centrifugal block 310 cannot be thrown out. When the baffle rod rotates at high speed, the centrifugal force generated can overcome the elastic force of the first elastic element 340, and the centrifugal block 310 is thrown out, so that the cleaning rod 320 on the outer wall of the centrifugal block 310 can abut against the inner wall of the mixing tank 100, thereby achieving the cleaning effect on the inner wall of the mixing tank 100.
[0056] Continue reading Figure 6 As one possible embodiment, a cleaning block 350 is provided above the rotation path of the centrifugal block 310. The bottom of the cleaning block 350 is connected to a cleaning bristle 351. The bottom of the cleaning bristle 351 can be inserted into the gap of the cleaning rod 320. The dirt in the middle of the cleaning rod 320 can be cleaned by the cleaning bristle 351.
[0057] The cleaning block 350 is elastically connected to the inner wall of the mixing box 100. One end of the cleaning block 350 is connected to a slider 360. The inner wall of the mixing box 100 is provided with a groove 390. A second elastic element 370 is connected between the slider 360 and the inner wall of the groove 390. The second elastic element 370 can be a spring or an elastic sheet. By energizing the spring, the spring can be controlled to contract, thereby achieving the up-and-down control of the cleaning block 350.
[0058] Continue reading Figure 7 , Figure 8 As one possible embodiment, one end of the baffle rod 220 is connected to a first meshing wheel 260, and the inner wall of the mixing tank 100 is connected to a first meshing ring 280. The first meshing ring 280 is intermittently arranged, and the first meshing wheel 260 meshes with the first meshing ring 280. When the baffle rod 220 revolves around the stirring rod 120, the baffle rod 220 rotates around its own central axis under the action of the first meshing wheel 260 and the first meshing ring 280.
[0059] In one possible embodiment, one end of the movable sleeve 240 is connected to a second meshing wheel 270, and a second meshing ring 290 is provided below the second meshing wheel 270. The second meshing wheel 270 meshes with the second meshing ring 290. When the turbulence rod 220 revolves around the stirring rod 120, the movable sleeve 240 rotates under the action of the second meshing wheel 270 and the second meshing ring 290.
[0060] Continue reading Figure 9 The figure shows a schematic diagram of the movement of the centrifuge block. See also... Figure 8 A drag-increasing cover 230 is connected to the baffle rod 220. When the baffle rod 220 rotates, due to the presence of the drag-increasing cover 230, the baffle rod 220 will rotate in one direction and maintain this angle when it revolves around the sun. When the first meshing wheel 260 at the end of the baffle rod 220 meshes with the first meshing ring 280, the baffle rod 220 will rotate in another direction under the meshing action. In summary, the baffle rod 220 can rotate back and forth in two directions, thereby allowing the centrifugal block 310 to sweep on the inner wall of the mixing tank 100 and increase the cleaning area.
[0061] Furthermore, by changing the angle of the centrifuge block 310, the centrifuge block 310 can intersect with the horizontal line for a period of time, and then the cleaning rod 320 on the outer wall of the centrifuge block 310 is rinsed by the impact force of the liquid.
