Description

Technical Field

[0001] The present invention relates to the field of sewage treatment equipment, in particular to a sewage treatment device with timed dripping of activated carbon-based water treatment agents. Background Art

[0002] In the field of sewage treatment, activated carbon is often used as a water treatment agent to remove organic pollutants, heavy metals and odors in sewage due to its strong adsorption properties. However, existing sewage treatment devices have many shortcomings when using activated carbon agents. On the one hand, the amount of agent added is usually a fixed value and cannot be dynamically adjusted according to the sewage flow and treatment speed, resulting in agent waste or insufficient treatment; on the other hand, the impurity separation and disinfection process often relies on additional equipment or complex processes, with high energy consumption and unstable separation effect, resulting in lengthy treatment processes. In addition, the existing devices have a low degree of automation and require more manual intervention, such as manually adjusting the agent flow, controlling drainage and slag discharge, and other cumbersome operations, which are not only inefficient but also prone to operational errors.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Compared with traditional sewage treatment equipment, the present invention has achieved significant improvements in treatment efficiency and intelligence through multi-dimensional technological innovation. In the impurity separation and disinfection links, the design of the air pump and the nano-gas disc breaks the limitations of traditional processes. The disinfecting gas is transmitted to the air outlet through the rotating shaft to form a bubble group, which can not only effectively kill bacteria and viruses in the sewage, but also use the drag force generated by the rising bubbles to carry the suspended particles and impurities adsorbed by the activated carbon to the water surface in a targeted manner, completing the impurity flotation. At the same time, through the linkage mechanism of the reduction motor and the corrugated sheath, the opening height of the inner cylinder can be accurately adjusted according to the actual thickness of the impurities being floated, realizing "slag discharge on demand", avoiding secondary pollution of the treated water quality by residual impurities, and greatly improving the impurity removal rate.

[0015] 2. In terms of the chemical addition system, the present invention breaks through the shackles of traditional quantitative dosing. It is based on an adaptive adjustment mechanism driven by centrifugal force, utilizes the positive correlation between the shaft speed and the sewage treatment load, and converts the motor speed signal into variable speed motion of the cone through a mechanical transmission chain of a rocker arm-drive disc-rubber wheel. When the sewage flow increases and the treatment speed accelerates, the shaft speed increases, and the rocker arm expands its angle under the action of centrifugal force, driving the rubber wheel to move up to the small diameter of the cone, greatly increasing the chemical delivery speed and ensuring that the chemical concentration is dynamically matched with the treatment requirements. This "dynamic braking" intelligent adjustment mode not only avoids the cost waste caused by excessive chemical, but also eliminates the problem of incomplete treatment due to insufficient chemical, providing an innovative path for the refined management of sewage treatment.

In the process of the rocker arms 133 opening under the action of the centrifugal force, the ends of the rocker arms 133 will slide inside the guide grooves 121 on the drive disk 120, and at the same time, the guide posts 142 at the ends of the rocker arms 133 can drive the drive disk 120 up and down under the limit of the guide grooves 132. Movement, when the driving disk 120 moves, it will drive the slider 136 to move up and down synchronously, and the slider 136 will drive the mounting frame 140 and the rubber wheel 131 to move along the slide bar 130 through the telescopic rod 139, so that the slide bar 130 will contact different positions of the upper and lower parts of the outer periphery of the cone 119. When the position of the rubber wheel 131 changes, the rotation ratio between the rubber wheel 131 and the cone 119 will change, so that the rotation speed of the rotating shaft 114 will drive the synchronous adjustment of the rotation speed of the cone 119, thereby realizing the synchronous adjustment of the speed of adding the agent, so that the speed of adding the agent can be faster as the speed of sewage treatment is accelerated, which is beneficial to actual use.

The reduction motor 112 is installed at the bottom of the barrel body 101. One of the guide rods 107 is threadedly connected to the flange ring 116 through the threaded section, and the remaining guide rods 107 are all connected to the flange ring 116. The flange ring 116 is slidably connected, a plurality of sewage pipes 113 are installed on one side of the bottom of the barrel body 101, a drain pipe 110 is installed on one side of the middle of the bottom end of the barrel body 101, and a uniformly distributed stirring blade 117 is installed on the middle and lower part of the outer periphery of the rotating shaft 114. A nano gas disk 118 is installed in the middle of the stirring blade 117. Both sides of the nano gas disk 118 are provided with uniformly distributed air outlet holes 141. The nano gas disks 118 are connected to the inside of the rotating shaft 114 through a connecting pipe. The bottom of the rotating shaft 114 passes through the middle of the bottom end of the barrel body 101. The rotating shaft 114 is rotatably connected to the barrel body 101 through a sealed bearing. The bottom of the outer periphery of the bottom of the rotating shaft 114 is rotatably connected to an air inlet head 111. The air inlet head 111 is installed at the bottom of the barrel body 101, and the bottom of the air inlet head 111 is connected to an external air pump through a connecting pipe. Furthermore, in the specific implementation, people can start the air pump, and the air pump can introduce the disinfection gas into the rotating shaft 114 through the air inlet head 111. The disinfection gas will enter the nano gas disk 118 through the rotating shaft 114 and will be dispersed into countless tiny bubbles through the air outlet 141 and spread into the sewage, thereby being able to disinfect the sewage. In addition, the gas will continuously float up in the process, thereby being able to carry away the impurities precipitated in the sewage, thereby being able to achieve the flotation separation of the impurities after sewage treatment and the treated water. When the sewage treatment is completed, people can first start The reduction motor 112 is driven, and the connected guide rod 107 can be driven to rotate through the reduction motor 112. The flange ring 116 and the corrugated sheath 115 can be driven to descend through the thread on the upper part of the guide rod 107, so that the top of the opening 108 on the outer periphery of the inner cylinder 109 can be exposed, so that the sewage at the top of the inner cylinder 109 can overflow out of the inner cylinder 109 through the opening 108, enter the interior of the barrel body 101, and be discharged through the sewage pipe 113. After the impurities floated out of the upper part of the inner cylinder 109 are discharged, the treated water can be discharged through the drain pipe 110.

[0022] Working principle: In actual use, people can introduce the sewage to be treated into the diversion cone 123 through the water inlet on one side of the barrel body 101, and then the sewage will enter the inner cylinder 109 through the opening at the bottom of the diversion cone 123. At the same time, people can introduce the activated carbon composite agent into the cone 119 through the feed port 106, and then the agent will pass through the through hole 2 128 and the through hole 1 125 at the bottom and fall into the diversion cone 123. After that, under the guidance of the diversion cone 123, the agent will enter the inner cylinder 109, purify the sewage, and precipitate some impurities in the sewage. The operation of the servo motor 105 can drive the rotating shaft 114 to rotate, and the rotating shaft 114 can drive the stirring blade 117 to mix the sewage and the agent. , thereby accelerating the reaction speed of the medicine and sewage, which is beneficial to sewage treatment. During this process, people can start the air pump synchronously, and the air pump can introduce disinfection gas into the rotating shaft 114 through the air inlet head 111. The disinfection gas will enter the nano gas disk 118 through the rotating shaft 114 and will be dispersed into countless tiny bubbles through the air outlet 141 and spread into the sewage, thereby disinfecting the sewage. In addition, the gas will float continuously in this process, thereby entraining impurities precipitated in the sewage, thereby realizing the flotation separation of impurities after sewage treatment and treated water. When the sewage treatment is completed, people can first start the reduction motor 112, which can drive the connected guide rod 107 to rotate through the reduction motor 112, and the guide rod 107 is moved upward. The thread on the top can drive the flange ring 116 and the corrugated sheath 115 to descend, thereby exposing the top of the opening 108 on the outer periphery of the inner cylinder 109, so that the sewage at the top of the inner cylinder 109 can overflow out of the inner cylinder 109 through the opening 108, enter the interior of the barrel body 101, and be discharged through the sewage pipe 113. After the impurities floated out of the upper part of the inner cylinder 109 are discharged, the treated water can be discharged through the drain pipe 110. In actual use, during the operation of the servo motor 105, when the servo motor 105 drives the rotating shaft 114 to rotate, the counterweight blocks at the ends of the rocker arms 133 on both sides will change with the speed of the rotating shaft 114, causing the centrifugal force on themselves to change accordingly, so that the rocker arms 133 on both sides will change with the speed of the rotating shaft 114. The rotation speed of the rotating shaft 114 changes and the swing rod 133 is expanded into different amplitudes. When the swing rod 133 is opened under the action of centrifugal force, the end of the swing rod 133 will slide inside the slide groove 121 on the driving disk 120. At the same time, the guide column 142 at the end of the swing rod 133 can drive the driving disk 120 to move up and down under the limit of the guide groove 132. When the driving disk 120 moves, it will drive the slider 136 to move up and down synchronously. The slider 136 will drive the mounting frame 140 and the rubber wheel 131 to move along the slide rod 130 through the telescopic rod 139, so that the slide rod 130 will contact different positions of the upper and lower parts of the outer circumference of the cone 119. When the position of the rubber wheel 131 changes, the rotation ratio between the rubber wheel 131 and the cone 119 will change.The rotation speed of the rotating shaft 114 will drive the rotation speed of the cone 119 to be adjusted synchronously, thereby achieving synchronous adjustment of the speed of adding the reagent, so that the speed of adding the reagent can be increased as the speed of sewage treatment increases, which is beneficial to practical use.
