Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a dosing device for fluorescent wastewater. Background Technology

[0002] Fluorescent agent wastewater treatment equipment mainly employs the following technologies: physical adsorption, chemical oxidation, and biodegradation. Among these, physical adsorption utilizes adsorbents with high specific surface area, such as activated carbon and zeolite, to adsorb and remove fluorescent substances from wastewater. This method has low investment costs and relatively good removal efficiency.

[0003] According to a public notice of a fluorescent wastewater-specific powder reagent dosing device (Announcement No.: CN223033159U), in the above application, after the powder reagent enters the reaction zone and is fully mixed with the wastewater and adsorbs the characteristic pollutants of the wastewater, polyaluminum chloride and polyacrylamide are added to the water to cause the powder reagent to form a precipitate and finally separate from the treated clean water in the form of sludge.

[0004] However, in existing reagent addition processes, whether it is powder or liquid, the reagent is added from the top of the tank, which limits the diffusion range of the reagent in the reaction tank and reduces the actual effect of the reagent. In view of this, we propose a dosing device for fluorescent wastewater. Utility Model Content

[0005] The purpose of this invention is to provide a dosing device for fluorescent wastewater to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dosing device for fluorescent wastewater, comprising a tank, an inlet pipe fixedly installed on the top side wall of the tank, an outlet pipe fixedly installed on the bottom side wall of the tank, a servo motor fixedly installed on the bottom outer wall of the tank, and a rotating shaft fixedly installed through the bottom inner wall of the servo motor at the output end of the servo motor, wherein a dosing component for dispersing a wide range of reagents is provided on the side of the rotating shaft;

[0007] The drug delivery assembly includes a feeding chamber located on the top inner wall of a rotating shaft. A connecting groove is formed on the inner side wall of the rotating shaft. An arc-shaped plate is fixedly installed on the side wall of the rotating shaft. A discharge groove is formed on the inner surface of the arc-shaped plate. A discharge slider is slidably installed on the inner wall of the end of the arc-shaped plate away from the rotating shaft. Opening grooves are formed on the inner walls of both sides of the discharge slider. Connecting blocks are fixedly installed on both sides of the discharge slider. Springs are fixedly installed on the side walls of the connecting blocks.

[0008] Preferably, the top end of the rotating shaft penetrates the top inner wall of the tank, and the feeding chamber is located at the top of the rotating shaft, so as to continuously inject wastewater treatment agents into the feeding chamber. The bottom inner wall of the feeding chamber is provided with a spherical protrusion, so as to facilitate the discharge of the agents entering the feeding chamber.

[0009] Preferably, the connecting groove is connected to the feeding chamber and the discharging groove, so that during the continuous rotation of the shaft, due to the centrifugal force and the connection of the groove openings, the medicine can enter the discharging groove through the inside of the shaft.

[0010] Preferably, the bottom surface of the discharge trough is shaped like an inclined arc, and the discharge trough is high at the end near the rotating shaft and low at the end away from the rotating shaft, so that the medicine can be discharged outward under the action of centrifugal force and gravity.

[0011] Preferably, the inner walls on both sides of the bottom end of the discharge trough are provided with rectangular cavities whose width is adapted to the connecting block, and the two ends of the spring are fixedly connected to the side wall of the connecting block and the inner wall of the end of the rectangular cavity, respectively.

[0012] Preferably, the discharge slider is provided with a flow-dispersing component, which includes a rotating cylinder rotatably mounted on the inner wall of the discharge slider. An impeller is fixedly mounted at the end of the rotating cylinder. A circular hole adapted to the rotating cylinder is opened on the inner wall of the discharge slider. A wave groove is opened on the inner surface of the circular hole. A slide rod is slidably mounted on the inner wall of the end of the rotating cylinder away from the impeller. A rotating rod is fixedly mounted at the end of the slide rod. A flow-dispersing rod is fixedly mounted on the side wall of the rotating rod. A convex ball is fixedly mounted on the side wall of the rotating rod. The convex ball slides in cooperation with the wave groove.

[0013] Preferably, a disc is fixedly installed on the outer wall of the rotating drum, and a limiting groove adapted to the disc is opened on the inner wall of the circular hole, so that the rotating drum can only rotate on the inner wall of the discharge slider and will not fall off.

[0014] Preferably, the inner wall of the rotating drum is provided with a sliding groove that matches the sliding rod, and the turbulence rods are distributed in an alternating pattern on both sides of the rotating rod.

[0015] Compared with the prior art, this utility model provides a dosing device for fluorescent wastewater, which has the following beneficial effects:

[0016] 1. This fluorescent wastewater dosing device is driven by centrifugal force. The reagent can be transported from inside the rotating shaft through the connecting groove to the discharge trough of the arc plate. When the discharge slider slides outward, it can be added at multiple points and in multiple directions through the opening groove, which effectively expands the diffusion range of the reagent in the tank and overcomes the problem of uneven dispersion in the traditional top dosing method. This significantly improves the mixing efficiency and reaction sufficiency of the reagent and fluorescent wastewater, and enhances the wastewater treatment effect.

[0017] 2. This fluorescent wastewater dosing device uses water flow to drive the impeller to rotate. The combination of the corrugated groove and the convex ball causes the rotating rod to drive the turbulence rod to reciprocate within the discharge slider. This further disperses the reagent flowing through the open groove, forming finer particles or droplets. This not only expands the dispersion range of the reagent but also effectively prevents the open groove from being blocked by flocculation or impurity accumulation, thus improving the reliability and continuity of the device's operation.

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a dosing device for fluorescent wastewater, including a tank 1, an inlet pipe 2 fixedly installed on the top side wall of the tank 1, an outlet pipe 3 fixedly installed on the bottom side wall of the tank 1, a servo motor 4 fixedly installed on the bottom outer wall of the tank 1, a rotating shaft 5 fixedly installed through the bottom inner wall of the tank 1 at the output end of the servo motor 4, and a dosing assembly 6 for dispersing a large range of reagents provided on the side of the rotating shaft 5. The dosing assembly 6 includes a feeding chamber 61, a connecting groove 62, an arc plate 63, a discharge groove 64, a discharge slider 65, an opening groove 66, a connecting block 67, and a spring 68.

[0026] In one embodiment of this utility model, the feeding cavity 61 is opened on the top inner wall of the rotating shaft 5, the inner wall of the side of the rotating shaft 5 is provided with a connecting groove 62, the side wall of the rotating shaft 5 is fixedly installed with an arc plate 63, the inner surface of the arc plate 63 is provided with a discharge groove 64, the inner wall of the arc plate 63 away from the rotating shaft 5 is slidably installed with a discharge slider 65, the inner walls of both sides of the discharge slider 65 are provided with opening grooves 66, the two sides of the discharge slider 65 are fixedly installed with connecting blocks 67, and the side walls of the connecting blocks 67 are fixedly installed with springs 68.

[0027] Furthermore, the top of the rotating shaft 5 penetrates the top inner wall of the tank 1, and the feeding chamber 61 is located at the top of the rotating shaft 5, thereby continuously injecting wastewater treatment agents into the feeding chamber 61. At the same time, the connecting groove 62 is connected to the feeding chamber 61 and the discharging groove 64. Thus, as the rotating shaft 5 continues to rotate, due to the centrifugal force and the connection of the grooves, the agent can enter the discharging groove 64 through the inside of the rotating shaft 5, and finally be put into the inside of the tank 1 through the discharging slider 65.

[0028] Meanwhile, the bottom inner wall of the feeding chamber 61 is provided with a spherical protrusion, which facilitates the discharge of the medicine entering the feeding chamber 61. The bottom surface of the discharge trough 64 is sloping and arc-shaped, and the discharge trough 64 is higher near the rotating shaft 5 and lower away from the rotating shaft 5, thus facilitating the discharge of the medicine under the action of centrifugal force and gravity, making it easier to disperse into the interior of the tank 1. Specifically, the inner walls on both sides of the bottom of the discharge trough 64 have rectangular cavities with a width adapted to the connecting block 67, and the two ends of the spring 68... The connecting block 67 is fixedly connected to the side wall and the inner wall of the rectangular cavity end, respectively. During the continuous rotation of the rotating shaft 5, due to the centrifugal force, the discharge slider 65 will slide outward along the inner surface of the arc plate 63 to expose the opening groove 66, so that the feeding chamber 61, the connecting groove 62 and the discharge groove 64 form a complete channel, so that the reagent to be added can be smoothly dispersed into the interior of the tank 1, so that the fluorescent wastewater entering the tank 1 can get a more complete dispersion reaction effect of the reagent, and ensure the treatment effect of the wastewater.

[0029] In addition, the discharge slider 65 is provided with a turbulence assembly 7, which includes a rotating cylinder 71. The rotating cylinder 71 is rotatably mounted on the inner wall of the discharge slider 65. An impeller 72 is fixedly mounted at the end of the rotating cylinder 71. The inner wall of the discharge slider 65 is provided with a circular hole that matches the rotating cylinder 71. A wave groove 73 is provided on the inner surface of the circular hole. A slide rod 74 is slidably mounted on the inner wall of the end of the rotating cylinder 71 away from the impeller 72. A rotating rod 75 is fixedly mounted at the end of the slide rod 74. A turbulence rod 76 is fixedly mounted on the side wall of the rotating rod 75. A convex ball 77 is fixedly mounted on the side wall of the rotating rod 75. The convex ball 77 slides in cooperation with the wave groove 73.

[0030] In an embodiment of this utility model, a disc is fixedly installed on the outer wall of the rotating drum 71, and a limiting groove adapted to the disc is opened on the inner wall of the circular hole, so that the rotating drum 71 can only rotate on the inner wall of the discharge slider 65 without falling off. At the same time, a sliding groove adapted to the sliding rod 74 is opened on the inner wall of the rotating drum 71, so that the rotating drum 71 and the rotating rod 75 always maintain synchronous rotation and there will be no relative sliding.

[0031] Meanwhile, the baffle rods 76 are distributed in an alternating pattern on both sides of the rotating rod 75. As the rotating shaft 5 continues to rotate, the water flow drives the impeller 72 to rotate, which causes the rotating rod 75 to drive the baffle rods 76 to rotate continuously inside the discharge slider 65. This disperses the agent flowing through the opening groove 66 on the side of the discharge slider 65, making its dispersion range wider. It also avoids the opening groove 66 from being easily blocked by wastewater, thus improving the effectiveness of the device.

[0032] In this invention, wastewater treatment agents are continuously injected into the feeding chamber 61 at the top of the rotating shaft 5. The servo motor 4 drives the rotating shaft 5 to rotate. Under centrifugal force, the agents enter the discharge trough 64 in the arc plate 63 through the connecting groove 62. As the rotating shaft 5 continues to rotate, the discharge slider 65 slides outward along the arc plate 63 under centrifugal force, compressing the spring 68 and exposing the opening groove 66. This forms a complete channel between the feeding chamber 61, the connecting groove 62, and the discharge trough 64, allowing the agents to be discharged from the opening groove 66 and dispersed into the tank 1. Simultaneously, the water flow drives the impeller 72 to rotate, causing the rotating drum 71 to rotate. The convex ball 77 on the rotating rod 75 slides along the wave groove 73, causing the rotating rod 75 and the turbulence rod 76 to reciprocate within the discharge slider 65, further dispersing the agents flowing through the opening groove 66, expanding its dispersion range, preventing blockage, improving the mixing reaction effect of the agents and fluorescent wastewater, and ensuring wastewater treatment efficiency.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
