[0013] Furthermore, one end of the movable comb plate is fixed with a protrusion, and the other end of the movable comb plate is elastically connected with a spring guide post.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When a large amount of powder is fed into the feeding mechanism at once, the present invention will cause the powder to be dispersed and diverted by the vibration within the feeding mechanism, so that it can be evenly scattered from the feeding mechanism. The vibration of the powder can also delay the direct falling time of the powder, thereby reducing the possibility of the powder easily accumulating. This can reduce the problems of long mixing time, uneven mixing, and powder clumping caused by local concentrated feeding of powder.

[0017] 2. This invention can scrape and comb the powder on the liquid surface, breaking up and separating aggregated powder and flocculent clumps. At the same time, the comb structure can also perform a shearing action when rotating with the stirring mechanism, so that the flocculent clumps in the comb teeth can be sheared and dispersed into more soluble particles. This helps to improve the efficiency of drug dissolution and ensures that the powder is fully dissolved, ensuring the accuracy of drug dosing and avoiding problems such as inaccurate dosage and reduced sewage treatment effect caused by clumping residue.

[0018] 3. The turbulence mechanism of this invention generates a diffusing and spreading water flow on the liquid surface, thereby diffusing the powder concentrated in the feeding area outward, reducing the concentration and aggregation of the powder, and allowing the powder to disperse and dissolve in the water more quickly. At the same time, the reciprocating push of the turbulence mechanism, combined with the rotation of the dispersion mechanism, can better agitate the liquid on the upper layer of the liquid surface, further accelerating the dissolution efficiency of the powder. In addition, by using the turbulence mechanism and the dispersion mechanism on the upper layer of the liquid surface to directly agitate the added powder, the dissolution efficiency and effect are improved, while also reducing the power required by using the stirring mechanism alone. The high-speed rotation of the stirring mechanism is not required, which helps to make the overall agitation more gentle. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To address the technical problem of excessive powder being fed at once, where large amounts of powder struggle to disperse during descent and tend to accumulate in localized areas of the liquid surface, resulting in slow dissolution, such as... Figures 1-3 as well as Figure 8 and Figure 9 As shown, the following preferred technical solutions are provided: A high-precision wastewater dosing device includes a main chemical tank 1 and a control cabinet 2 located in front of the main chemical tank 1. The main chemical tank 1 is an existing three-chamber fully automatic wastewater dosing device, with the three chambers being a preparation chamber, a maturation chamber, and a storage chamber. Its specific control and working principle will not be elaborated here. A water inlet pipe 3 is connected to one side of the main chemical tank 1, and the input end of the water inlet pipe 3 is connected to the preparation chamber of the main chemical tank 1, allowing water to be added into the main chemical tank 1. A pneumatic valve 4 is installed on one side of the middle of the water inlet pipe 3, and a flow meter 5 is installed on the other side of the middle of the water inlet pipe 3. By controlling the electromagnetic flowmeter 5 and the pneumatic valve 4 through the control cabinet 2, the fluctuation of the influent flow can be reduced, which is conducive to improving the concentration of the medicine. Four sets of support frames 30 are fixedly installed on the top of the main medicine tank 1, and pressure sensors 40 are fixed on the top of each of the four sets of support frames 30. Powder box 9 is fixedly installed on the top of the pressure sensor 40. The powder box 9 is symmetrically installed in a four-point suspension manner between the pressure sensor 40 and the three sets of support frames 30. The pressure sensor 40, together with the control cabinet 2, can detect and identify the weight of the powder box 9 when it is being fed.

[0023] A feeding mechanism 10 is installed at the bottom of the powder box 9. The feeding mechanism 10 is a high-precision servo screw feeder, driven by a servo motor and fed back by a pressure sensor 40. It can precisely control the amount of powder fed into the powder box 9, thereby ensuring the accuracy of the dosing. The powder in the powder box 9 is a high-molecular-weight polyacrylamide powder for wastewater treatment. A feeding mechanism 20 is set below the front end of the feeding mechanism 10. The feeding mechanism 20 is connected to the preparation cavity of the main medicine box 1, so that the powder conveyed from the feeding mechanism 10 can fall into the preparation cavity of the main medicine box 1 through the feeding mechanism 20. The main medicine box 1 is equipped with a feeding mechanism 10 at the top. It is equipped with three sets of stirring mechanisms 6, which are mixers. The three sets of stirring mechanisms 6 are respectively set in the preparation chamber, maturation chamber and storage chamber of the main medicine tank 1, so that the medicine liquid in the main medicine tank 1 can be stirred and mixed evenly. When too much medicine powder is fed into the feeding mechanism 10 at one time, a large amount of powder is difficult to disperse when falling and tends to accumulate in a local area of ​​the liquid surface. Therefore, when stirring, the powder cannot be quickly carried into the water body and tends to float on the liquid surface for a long time, which will affect the efficiency of medicine preparation. At the same time, a large amount of medicine powder accumulated on the liquid surface is also prone to agglomeration during stirring.

[0024] When a large amount of powder is fed into the feeding mechanism 10, the spiral power structure of the feeding mechanism 10 will drive the structure inside the feeding mechanism 20 to vibrate. This causes the large amount of powder to be dispersed and diverted as it passes through the vibration inside the feeding mechanism 20, and it can eventually fall evenly from the feeding mechanism 20. The vibration of the powder can also delay the time when the powder falls directly, thereby reducing the possibility of the powder easily accumulating. This can reduce the problems of long mixing time, uneven mixing, and powder clumping caused by local concentrated feeding of powder. A dispersing mechanism 7 is located in the middle of the stirring mechanism 6. The dispersing mechanism 7 is separately installed on top of the stirring mechanism 6 within the preparation chamber of the main medicine tank 1, and is positioned below the feeding mechanism 20. When the medicine powder falls from the feeding mechanism 20, it falls into the dispersing mechanism 7. While the stirring mechanism 6 in the preparation chamber is rotating and agitating, it simultaneously drives the dispersing mechanism 7 to rotate. The dispersing mechanism 7 has a comb-like structure. When a large amount of medicine powder aggregates and forms clumps, the rotation of the comb-like structure of the dispersing mechanism 7 scrapes and combs the medicine powder on the liquid surface, breaking up and separating the aggregated medicine powder and flocculent clumps. Simultaneously, as the comb-tooth structure rotates with the stirring mechanism 6, it also performs a shearing action. This allows the comb-tooth structure to generate shearing force on the flocculent clumps in the gaps between the teeth, dispersing the powder clumps into more easily soluble particles. This improves the efficiency of drug dissolution and ensures that the powder is fully dissolved, guaranteeing the accuracy of drug dosing and avoiding problems such as inaccurate dosage and reduced wastewater treatment effect caused by clump residue. At the same time, the dispersing mechanism 7 of the comb-tooth structure also disturbs the upper layer of the liquid surface when it rotates. Combined with the stirring mechanism 6's agitation inside the liquid, this results in faster and better dissolution of the powder.

[0025] A turbulence-inducing mechanism 8 is provided on the outer side of the dispersing mechanism 7, and multiple sets of turbulence-inducing mechanisms 8 are arranged in a ring around the dispersing mechanism 7. When the comb-shaped dispersing mechanism 7 rotates and performs a shearing action, it drives the multiple sets of turbulence-inducing mechanisms 8 to perform a reciprocating pushing action. When the dispersing mechanism 7 rotates, it generates a water flow that rotates radially around the rotating shaft of the stirring mechanism 6 on the liquid surface. When the turbulence-inducing mechanism 8 reciprocates, it generates a diffusing and spreading water flow on the liquid surface, thereby diffusing the powder concentrated in the feeding area outward, reducing the concentration and agglomeration of the powder, and allowing the powder to disperse and dissolve in the water more quickly. At the same time, the turbulence-inducing mechanism... The reciprocating motion of 8, combined with the rotation of the dispersion mechanism 7, can better agitate the liquid on the surface, thereby further accelerating the dissolution efficiency of the powder. At the same time, the disturbance mechanism 8 and the dispersion mechanism 7 directly agitate the added powder on the upper layer of the liquid, which improves the dissolution efficiency and effect, while also reducing the power required for stirring by the stirring mechanism 6 alone. The stirring mechanism 6 does not need to rotate at high speed, which helps to make the overall stirring more gentle and ensure the effectiveness of the device. The main medicine tank 1 is connected to the bottom of the medicine outlet pipe 50, through which the prepared medicine in the main medicine tank 1 can be discharged.

[0026] The feeding mechanism 10 includes a conveying motor 101 fixed on the main medicine box 1, and the output end of the conveying motor 101 is connected to a screw shaft 102. The front end of the screw shaft 102 is fitted with a guide tube 103. The conveying motor 101 and the screw shaft 102 constitute a high-precision servo screw feeder. With the feedback of the pressure sensor 40, the amount of medicine powder conveyed in the powder box 9 can be precisely controlled, thereby improving the accuracy of medicine dispensing.

[0027] The feeding mechanism 20 includes a feeding pipe 201 fixed on the main medicine box 1. The feeding pipe 201 is connected to the preparation cavity of the main medicine box 1, and the top of the feeding pipe 201 is closed. A connecting shaft 202 is fixed to the middle of one end of the spiral shaft 102, and a cam disk 203 is fixed to one side of the connecting shaft 202. The outer surface of the cam disk 203 is provided with several arc protrusions. When the spiral shaft 102 rotates to feed the material, the connecting shaft 202 can drive the cam disk 203 to rotate.

[0028] Two sets of connecting rods 204 are fixed above and below one side surface of the cam disk 203, and a cam ring 205 is fixed to one end of the connecting rod 204. The cam ring 205 is rotatably connected to the guide tube 103. The outer surface of the cam ring 205 is also provided with several arc protrusions in a ring. The cam disk 203 and the cam ring 205 are symmetrically arranged on both sides inside the feed tube 201. When the cam disk 203 rotates, the connecting rods 204 can drive the cam ring 205 to rotate synchronously on the guide tube 103.

[0029] A fixed mesh plate 209 is fixed in the middle of the inner side of the feed pipe 201. The middle of the fixed mesh plate 209 is mesh-like, and the diameter of the mesh is larger than the diameter of the powder, which can ensure the falling of the powder. Springs 208 are fixed on both sides of the upper surface of the fixed mesh plate 209. Springs 208 are wrapped with elastic sleeves to prevent the powder from entering and interfering with the elastic deformation of springs 208. A movable mesh plate 206 is fixed above springs 208. The middle of the movable mesh plate 206 is also mesh-like, and the diameter of the mesh is larger than that of the fixed mesh plate 209, which can also ensure the falling of the powder. At the same time, the middle of both the fixed mesh plate 209 and the movable mesh plate 206 is a metal mesh with a Teflon coating, so that the double-layered fixed mesh plate 209 and movable mesh plate 206 will not interfere with the falling of the powder or cause it to stick. Protrusions 207 are fixed on both sides of the upper surface of the movable mesh plate 206.

[0030] When the spiral shaft 102 rotates to feed material, causing the cam disk 203 and cam ring 205 to rotate, the arc-shaped protrusions on the surfaces of the rotating cam disk 203 and cam ring 205 continuously press against the protrusion 207 and the movable screen plate 206. This causes the movable screen plate 206 to reciprocate up and down on the fixed screen plate 209 under the action of the spring 208. The maximum downward movement of the movable screen plate 206 will bring it into contact with the fixed screen plate 209. When the spiral shaft 102 feeds a large amount of powder at once, the rotating spiral shaft 102 will eventually drive the movable screen plate 206 to vibrate. When a large amount of powder falls onto the surface of the movable screen plate 206, it can be treated by vibration. The multiple vibrations of the movable screen plate 206 and the fixed screen plate 209 are utilized. The porous structure allows the powder to be dispersed and distributed, eventually falling evenly from the feed pipe 201. The double mesh formed by the movable mesh plate 206 and the fixed mesh plate 209 can delay the direct fall of the powder, reducing the possibility of powder accumulation. This reduces the problems of prolonged mixing time, uneven mixing, and powder clumping caused by localized concentrated powder feeding. At the same time, when the movable mesh plate 206 vibrates, it comes into contact with the fixed mesh plate 209, and the relative contact between the two mesh plates creates a squeezing effect on the powder. This not only disperses the powder but also crushes small clumps, ensuring that the final falling powder is fine powder that meets the particle size requirements, thus reducing the probability of powder clumping on the liquid surface from the source.

[0031] To address the technical problem of large amounts of powder accumulating on localized areas of the liquid surface during material feeding, easily forming insoluble lumps or clusters, leading to inaccurate dosage and reduced wastewater treatment efficiency, such as... Figures 1-6 As shown, the following preferred technical solutions are provided: The stirring mechanism 6 includes a stirring motor 61 fixed on the upper surface of the main medicine tank 1, and the output end of the stirring motor 61 is connected to a stirring shaft 62. A stirring blade 63 is fixed below the surface of the stirring shaft 62. The stirring motor 61, stirring shaft 62 and stirring blade 63 are provided in the preparation chamber, maturation chamber and storage chamber of the main medicine tank 1 to complete the stirring and mixing of the medicine liquid in the main medicine tank 1.

[0032] The dispersing mechanism 7 includes a mounting sleeve 71 slidably mounted on a stirring shaft 62. A limiting slide rail 72 is slidably mounted in the middle of the mounting sleeve 71 and is fixed to the stirring shaft 62. A stop block is fixed at the bottom of the limiting slide rail 72. The mounting sleeve 71 can move up and down along the limiting slide rail 72. The stop block can restrict the sliding position of the mounting sleeve 71. Several fixed comb plates 73 are fixedly fixed in a ring below the outer surface of the mounting sleeve 71. A sliding groove 74 is opened in the middle of the fixed comb plate 73, and a movable comb plate 75 is slidably mounted inside the sliding groove 74. The mounting sleeve 71 is made of a floating plastic material, allowing the mounting sleeve 71 to move along the surface of the stirring shaft 62. The stirring shaft 62 floats the fixed comb plate 73 and the movable comb plate 75 on the liquid surface, with the comb teeth of the fixed comb plate 73 and the movable comb plate 75 just exposed on the liquid surface after floating. The mounting sleeve 71, limited by the limiting slide rail 72, can synchronously drive the mounting sleeve 71 and the fixed comb plate 73 and the movable comb plate 75 to rotate radially on the liquid surface when the stirring shaft 62 rotates. The falling powder falls within the rotation range of the fixed comb plate 73, so that the comb-shaped fixed comb plate 73 and the movable comb plate 75 can scrape and comb the powder on the liquid surface when rotating, so that the aggregated powder and flocculent clumps can be broken up and separated, thereby reducing the aggregation of powder and the possibility of powder clumping.

[0033] One end of the movable comb plate 75 is fixed with a protrusion 76, and the other end of the movable comb plate 75 is elastically connected to a spring guide post 77. A sealing plate 78 is provided on the outside of the spring guide post 77. The spring guide post 77 consists of a guide rod inserted into the movable comb plate 75 and a spring outside the guide rod, allowing the movable comb plate 75 to elastically extend and retract within the sliding groove 74 using the spring guide post 77. The sealing plate 78 can block the space between the spring guide post 77 and the sliding groove 74, preventing liquid from entering the elastic deformation space of the spring guide post 77 and causing interference. A floating ring 79 is provided on the outside of the fixed comb plate 73, and the floating ring... The inner surface of the float ring 79 is provided with several extrusion heads 710. Fixed sliders 711 are fixed on both sides of the outer surface of the float ring 79. A limit slide rail 712 is slidably provided in the middle of the fixed slider 711. The limit slide rail 712 is fixed on the main medicine box 1. A stop block is fixed at the bottom of the limit slide rail 712, which allows the float ring 79 to slide up and down on the surface of the limit slide rail 712 using the fixed sliders 711. The stop block can limit the sliding position of the float ring 79. The float ring 79 is made of floating plastic material, and after floating, it is on the same horizontal liquid surface as the movable comb plate 75 and the fixed comb plate 73.

[0034] When the movable comb plate 75 is driven by the stirring shaft 62 to rotate radially around the floating ring 79, the protrusion 76 at the front end of the movable comb plate 75 continuously squeezes and relaxes with multiple sets of extrusion heads 710. This allows the protrusion 76 to move the movable comb plate 75 and the fixed comb plate 73 alternately under the action of the spring guide post 77. This allows the two sets of comb teeth to perform a shearing action, so that when the movable comb plate 75 and the fixed comb plate 73 rotate, they can form a shearing force on the flocculent clumps in the comb teeth. This allows the powder clumps to be sheared and dispersed into more easily soluble particles, thereby improving the efficiency of drug dissolution and ensuring that the powder is fully dissolved, improving the accuracy of drug dosing and avoiding dosing errors caused by clump residue. Problems such as inaccurate drug dosage and decreased sewage treatment effect are addressed. At the same time, the rotation of the movable comb plate 75 and the fixed comb plate 73 can also create disturbance on the upper layer of the liquid surface. Combined with the stirring of the stirring blade 63 inside the liquid, the drug powder can dissolve faster and more effectively. Meanwhile, the floating ring 79 and the mounting sleeve 71 can move up and down along the limiting slide rail 2 712 and the limiting slide rail 1 72 respectively according to the liquid level. The length of the limiting slide rail 2 712 and the limiting slide rail 1 72 is adapted to the height of the liquid level change under normal use in the main medicine tank 1. This ensures that the comb teeth of the movable comb plate 75 and the fixed comb plate 73 are always exposed on the surface of the liquid according to the liquid level change, thereby ensuring the effect of dispersing the drug powder and preventing agglomeration.

[0035] To address the technical problem of slow powder diffusion and the need for significant stirring power to ensure dissolution, such as... Figures 1-4 as well as Figure 7 As shown, the following preferred technical solutions are provided: The turbulence mechanism 8 includes several fixed sleeves 81 fixed on the floating ring 79, and the fixed sleeves 81 are arranged in a ring about the floating ring 79. A sliding rod 82 is slidably arranged inside the fixed sleeve 81, and one end of the sliding rod 82 is fixed to one end of the extrusion head 710.

[0036] A spring 83 is fixed to one end of the inner sleeve 81, and the other end of the spring 83 is fixed to the extrusion head 710. A baffle 84 is fixed to one side of the outer surface of the sliding rod 82. The spring 83 and the spring guide post 77 have the same compression force and can be compressed simultaneously when subjected to force. When the protrusion 76 extrudes the extrusion head 710, causing the fixed comb plate 73 to compress, it will simultaneously generate the extrusion force of the spring 83 on the extrusion head 710, causing the extrusion head 710 and the protrusion 76 to compress simultaneously. When the extrusion head 710 is compressed, it will push the sliding rod 82 and the baffle 84 to move. At the same time, when the protrusion 76 disengages from the extrusion head 710, the extrusion force of the extrusion head 710 disappears, causing the sliding rod 82 and the baffle 84 to return to their original positions. When the sliding rod 82 and the baffle 84 reciprocate, they will generate pressure on the liquid surface. The agitation of the water flow disperses the powder concentrated in the feeding area, reducing powder aggregation and allowing it to dissolve more quickly. Simultaneously, the reciprocating motion of the baffle plate 84, combined with the rotation of the movable comb plate 75 and the fixed comb plate 73, further agitates the liquid surface, accelerating powder dissolution. The baffle plate 84, movable comb plate 75, and fixed comb plate 73 directly agitate the added powder, improving dissolution efficiency and effectiveness while reducing the power required for agitation using only the stirring blade 63. The absence of high-speed rotation of the stirring blade 63 allows for gentler agitation, preventing excessive surface agitation and ensuring optimal device performance.
