Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a treatment agent spraying device for high COD sewage treatment. Background Art

[0002] The treatment agent spraying device for high COD sewage treatment is a device specially used to evenly spray chemical treatment agents (such as COD degradation agents, oxidants, etc.) into sewage, aiming to efficiently reduce the chemical oxygen demand (COD) in sewage.

[0003] The treatment agent spraying device for high COD sewage treatment in the prior art is usually equipped with a floating device and placed above the sewage liquid surface. A large-scale spraying treatment is performed in the center area of ​​the sewage liquid surface. However, during use, since the spray treatment agent is internally mixed with solid impurities in the mixture, some spray holes are blocked during the continuous spraying treatment process. The current unblocking operation usually requires shutdown treatment, inspection of the blocked area, and special unblocking after detection. The actual operation is cumbersome, and for the spraying device placed above the sewage liquid surface, the actual detection and unblocking operations are more difficult. At the same time, for large-area spraying treatment, part of the atomized treatment agent is actually mixed with air and suspended and dispersed in the air.

[0015] The beneficial effects of the present invention are as follows: (1) The present invention drives the multi-mode switching component to rotate slowly through a driving mechanism, and cooperates with the multi-mode switching component rotating in the spray barrel and the treatment agent input into the spray barrel. On the one hand, during the rotation process, the cleaning component in the multi-mode switching component cooperates with the inner end of the spray hole intermittently rubs during the rotation process, and during the period of relative friction during the rotation, the cleaning component is controlled by the magnetic power vibration component to perform impact treatment at the inner end of the spray hole, thereby realizing self-cleaning during the spraying process, avoiding the clogging of the spray hole by solid particles in the mixed treatment agent, and utilizing the intermittent friction and reciprocating impact under dynamic rotation to complete the self-cleaning treatment of the spray hole, and the self-cleaning and spraying treatment occur simultaneously, without the need for shutdown treatment, with high spraying efficiency and good clearing effect.

The middle chamber and the outer port are gradually connected to the spray hole during the rotation process to achieve dynamic adjustment of the spray hole, reduce the number of spray holes and change the angle of independent spraying. The former increases the outlet pressure of the spray hole while reducing the number of spray holes, and improves the ability of the treatment agent to be sprayed into the sewage.

[0017] (3) The present invention utilizes the rotation of the multi-mode switching component again, cooperates with the position adjustment of the through-adapter slot and the cleaning component, and utilizes the additional suction pump and suction pipe. When the through-adapter slot is rotated to the upper side, the suction pump and the suction pipe are connected to each other, thereby sucking the wet air after spraying in the environment into the through-adapter slot, and sucking the residual dispersed treatment agent in the mixed wet air into the through-adapter slot and adsorbing it in multiple groups of distributed cleaning components. The densely arranged brush-shaped arc cleaning brushes of the cleaning component are utilized to allow air to pass through the gap while adsorbing and collecting the treatment agent in the wet air passing through in a wet state, thereby achieving the treatment of the ambient air, improving the air quality after the sewage top spraying treatment, and avoiding the dispersed treatment agent in the mixed wet air from polluting the environment.

[0018] (4) The present invention reuses the adsorption and collection capacity of the cleaning component. When the multi-mode switching component is rotated downward, the cleaning component that adsorbs and collects the treatment agent is at the bottom. Under the flushing of the introduced treatment agent liquid, the treatment agent of the mobile phone is mixed again in the treatment agent liquid and directly sprayed out along the spray hole, thereby realizing the secondary spraying after the adsorbed and collected treatment agent is recovered. There is no need for additional treatment of the adsorbed and collected treatment agent, and subsequent reuse can be completed directly, with good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

A middle cavity 14 is symmetrically provided inside the switching sleeve 9, and outer ports 15 are symmetrically provided on both sides of the switching sleeve 9, the outer ports 15 are communicated with the middle cavity 14, an intermediate shaft 10 is fixedly sleeved inside the switching sleeve 9, an internal cavity is provided inside the switching sleeve 9, a magnetic dynamic vibration component 19 is fixedly provided in the internal cavity, a cleaning component 17 is located in the through-adapting groove 12, a suction pump 20 is fixedly provided on the top of the spray barrel 5, the suction end of the suction pump 20 is communicated with the inside of the spray barrel 5, and the other end of the spray barrel 5 is fixedly connected with a suction pipe 21, and when the cleaning component 17 rotates to the upper side, it absorbs the treatment agent in the air sucked in through the suction pipe 21.

[0023] Embodiment 1: When in use, as the liquid pump on the storage box pumps the treatment agent into the distribution chamber 22 and inputs it into the spray barrel 5 through the connecting pipe 6 and the liquid inlet hole 8, the driving mechanism 11 is kept started, driving the intermediate shaft 10 to rotate, so that the multi-mode switching component rotates in the spray barrel 5, and the switching sleeve 9 rotates. When the connecting chamber 13 rotates to the bottom, the treatment agent is fed and sprayed downward directly along the bottom spray hole 7 through the connecting chamber 13, and acts on the sewage pool. During the rotation process, the outer port 15 corresponding to the middle chamber 14 on one side rotates and approaches the spray hole 7. The spray hole 7 on one side of the bottom spray hole 7 is gradually blocked by the outer side of the switching sleeve 9, and the number of spray holes of the bottom spray hole 7 is reduced. The spray pressure of the unblocked and sealed spray hole 7 increases and is sprayed into the sewage pool. During the continued rotation process, the outer port 15 is connected with the bottom spray hole 7. At this time, the left spray hole 7 and the right spray hole 7 at the bottom of the spray barrel 5 are sprayed synchronously, while the middle spray hole 7 is sealed. When the outer port 15 is connected one by one along the arc-shaped spray holes 7 at the bottom, the single-row spray holes 7 at the bottom of the spray barrel 5 are sprayed independently, and the treatment liquid is further sprayed into the sewage. During the rotation process, the independent spraying in different directions is continuously switched. When the through-adapter slot 12 rotates to the bottom and is connected to the spray hole 7, and the cleaning component 17 gradually rotates to the top of the spray hole 7, the treatment agent is fed and filtered through each group of arc-shaped cleaning brushes 172 and sprayed along the spray hole 7, and as the arc-shaped cleaning brush 172 rotates, it rubs against the spray hole 7 on the inner wall of the spray barrel 5 to complete the clearing. At the same time, the magnetic power vibration component 19 is started, and the electromagnet 196 is started intermittently. When the electromagnet 196 is started, it is energized to generate magnetic attraction, and generates a repulsive force on the magnetic ring 193 with the same magnetic pole, pushing the sleeve 191 to slide along the intermediate shaft 10, compressing the spring 2 195, so that the protrusion 192 pushes the movable rod 173 of the cleaning component 17, so that the movable rod 173 reciprocates and compresses the spring 1 175, and simultaneously drives the arc plate 171 to vibrate reciprocatingly, so that the rotating arc-shaped cleaning brush 172 clears the spray hole 7 on the inner wall of the spray barrel 5 in a reciprocating vibration state.

[0024] First, the multi-mode switching component is driven to rotate slowly by the driving mechanism 11, and the multi-mode switching component rotating in the spray barrel 5 and the treatment agent input into the spray barrel 5 are coordinated. On the one hand, the cleaning component 17 in the multi-mode switching component is coordinated during the rotation process, and the inner end of the spray hole 7 is intermittently rubbed during the rotation process. During the period of relative friction during rotation, the magnetic power vibration component 19 is used to control the cleaning component 17 to perform impact treatment at the inner end of the spray hole 7, thereby realizing self-cleaning during the spraying process, avoiding solid particles in the mixed treatment agent from clogging the spray hole 7, and utilizing intermittent friction and reciprocating impact under dynamic rotation to complete the self-cleaning treatment of the spray hole 7. The self-cleaning treatment of the spray hole 7 occurs simultaneously with the spraying treatment, without the need for shutdown treatment, with high spraying efficiency and good clearing effect.

[0025] In addition, by utilizing the rotation of the switching sleeve 9 in the multi-mode switching assembly again, the connecting chamber 13, the middle chamber 14 and the through-adapting groove 12 are driven to rotate. The connecting chamber 13 is directly connected with the spray hole 7 after rotation and the spraying operation is performed, and the middle chamber 14 and the outer port 15 are gradually connected with the spray hole 7 during the rotation process to realize dynamic adjustment of the spray hole 7, reduce the number of spraying holes 7 and change the angle of independent spraying. The former enhances the outlet pressure of the spray hole 7 while reducing the number of spray holes, and improves the ability of the treatment agent to be sprayed into the sewage. The latter realizes enhanced injection treatment at different angles. In the actual spraying process of the sewage treatment agent above the water surface, it has spray intensity adjustment and angle socketing, enhances the ability of the treatment agent to be sprayed into the sewage, improves the sewage treatment effect, and during the rotation of the switching sleeve 9, intermittently completes full-open spraying, enhanced spraying and self-cleaning spraying and other multi-mode spraying treatments, and the actual spraying effect is good.

[0026] Embodiment 2: When spraying, the suction pump 20 is started. When the through-adapting slot 12 rotates upward, the suction pump 20 sucks the air in the suction pipe 21 through the through-adapting slot 12, so that the suction pipe 21 sucks the atomized and dispersed wet air containing the treatment agent in the air toward the spraying area, and the sucked wet air enters the through-adapting slot 12, and the treatment agent in the wet air adheres to the arc-shaped cleaning brush 172, completing the adsorption and collection of the treatment agent in the wet air, and when the arc-shaped cleaning brush 172 rotates downward and contacts the spraying hole 7, the introduced treatment agent mixture flushes the collected treatment agent adsorbed on the arc-shaped cleaning brush 172, and remixes and sprays out; When the treatment agent is stopped from being pumped out and the through-adapter slot 12 is kept stationary at the top, the wet air mixed with the treatment agent in the environment is sucked into the through-adapter slot 12, and the dispersed treatment agent is adsorbed in the cleaning component 17, completing the environmental treatment.

[0027] First, by utilizing the rotation of the multi-mode switching component again, cooperating with the position adjustment of the through-adapting slot 12 and the cleaning component 17, and utilizing the additional suction pump 20 and the suction pipe 21, when the through-adapting slot 12 is rotated to the upper side, the conduction with the suction pump 20 and the suction pipe 21 is achieved, so that the wet air after spraying in the environment is sucked into the through-adapting slot 12, and the residual dispersed treatment agent in the mixed wet air is sucked into the through-adapting slot 12, and adsorbed in multiple groups of distributed cleaning components 17, and the densely arranged brush-shaped arc cleaning brushes 172 of the cleaning component 17 are utilized to allow air to pass through the gap while adsorbing and collecting the treatment agent in the wet air passing through in a wet state, so as to achieve the treatment of the ambient air, improve the air quality after the top spraying of the sewage, and avoid the dispersed treatment agent from polluting the environment in the mixed wet air.

[0028] In addition, by reusing the adsorption and collection capacity of the cleaning component 17, when the multi-mode switching component is rotated downward, the cleaning component 17 that adsorbs and collects the treatment agent is at the bottom, and under the flushing of the introduced treatment agent liquid, the treatment agent of the mobile phone is mixed again in the treatment agent liquid, and is directly sprayed along the spray hole 7, thereby realizing the secondary spraying after the recovery of the adsorbed and collected treatment agent.
