Description

Technical Field

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

[0002] A treatment agent spraying device for high COD sewage treatment is a device specifically 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] In the existing treatment agent spraying devices for high COD sewage treatment, floating devices are usually carried and placed above the sewage liquid surface. By spraying in a large range in the central area of the sewage liquid surface, however, during the use process, since there are solid impurities doped inside the sprayed treatment agent during mixing, during the continuous spraying process, there is a situation where some spraying holes are blocked. Currently, the clogging removal operation usually requires shutting down the machine, checking the blocked area, and performing special clogging removal after detection. The actual operation is troublesome, and for the spraying device placed above the sewage liquid surface, the actual detection and clogging removal operations are more difficult. At the same time, for large-area spraying treatment, actually, some atomized treatment agents are mixed with air and suspended and dispersed in the air. After long-term spraying treatment, a large amount of residual treatment agents are mixed in the ambient air, causing environmental pollution, and the comprehensive use effect is not good.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) The present invention drives the slow rotation of the multi-condition switching component through the driving mechanism, cooperates with the multi-condition switching component rotating in the spraying cylinder and the treatment agent input into the spraying cylinder. On the one hand, during the rotation process, it cooperates with the cleaning component in the multi-condition switching component, intermittently frictions the inner end of the spraying hole during the rotation process, and during the relative friction period of the rotation, uses the magnetic force vibration component to control the cleaning component to perform impact treatment at the inner end of the spraying hole, so as to achieve self-cleaning blockage during the spraying process, avoid the solid particles in the mixed treatment agent from blocking the spraying hole, and complete the self-cleaning blockage treatment of the spraying hole by using the intermittent friction and reciprocating impact under dynamic rotation. Moreover, the self-cleaning blockage and the spraying treatment occur simultaneously, without the need for shutdown treatment, with high spraying efficiency and good blockage removal effect.

[0019] (2) The present invention drives the rotation of the switching sleeve column in the multi-condition switching component again. During the rotation of the communication cavity, the intermediate cavity and the through adaptation groove, the communication cavity is directly communicated with the spraying hole after rotation for spraying operation, and the intermediate cavity and the outer side port are gradually communicated with the spraying hole during the rotation process, realizing the dynamic adjustment of the spraying hole, reducing the number of spraying holes and changing the angle of independent spraying. The former enhances the outlet pressure of the spraying hole when reducing the number of spraying holes, improving the ability of the treatment agent to be sprayed into the sewage. The latter realizes the enhanced spraying treatment in different angular directions. During the spraying process above the water surface of the actual sewage treatment agent, it has spraying intensity adjustment and angle socketing, enhancing the ability of the treatment agent to be sprayed into the sewage, improving the sewage treatment effect, and intermittently completing multi-condition spraying treatments such as full-open spraying, enhanced spraying and self-cleaning spraying during the rotation of the switching sleeve column, with good actual spraying effect.

[0020] (3) By reusing the rotation of the multi-condition switching component, cooperating with the position adjustment of the through-adaptation slot and the cleaning component, and utilizing the additional suction pump and suction pipe, when the through-adaptation slot rotates to the upper side, conduction with the suction pump and the suction pipe is achieved, so as to suck the wet air sprayed in the environment into the through-adaptation slot, and suck the residual and dispersed treatment agent in the mixed wet air into the through-adaptation slot and adsorb it in multiple groups of distributed cleaning components. By using the densely arranged brush-shaped arc cleaning brushes of the cleaning component, while allowing air to pass through the gaps, the treatment agent in the passing wet air is adsorbed and collected in a wet state, realizing the treatment of environmental air, improving the air quality after spraying treatment on the top of sewage, and avoiding the pollution of the environment by the dispersed treatment agent in the mixed wet air.

[0021] (4) By reusing the adsorption and collection ability of the cleaning component, when the multi-condition switching component rotates to the lower side, the cleaning component adsorbed and collected with the treatment agent is below, and under the flushing of the introduced treatment agent liquid, the collected treatment agent is mixed in the treatment agent liquid again and directly sprayed out along the spraying holes where it is located, realizing the secondary spraying after the recovery of the adsorbed and collected treatment agent. There is no need to perform additional treatment on the adsorbed and collected treatment agent, and the subsequent reuse is directly completed, with good use effects.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a treatment agent spraying device for high-COD sewage treatment, including a mounting plate 1 and a floating carrier. A rotating cylinder 2 is rotatably mounted on the top of the mounting plate 1. An assembly component 3 and an angle adjustment component 4 are respectively provided at the top of the rotating cylinder 2. The outer end of the angle adjustment component 4 is fixedly connected to a spraying cylinder 5. Spraying holes 7 are arranged in an array on the bottom surface of the spraying cylinder 5. A multi-condition switching component is rotatably sleeved inside the spraying cylinder 5. A cleaning component 17 is nested outside the multi-condition switching component and is distributed in an array. The multi-condition switching component includes a switching sleeve column 9, through adaptation grooves 12 and communication cavities 13 symmetrically opened on the outside of the switching sleeve column 9, an intermediate cavity 14 symmetrically opened inside the switching sleeve column 9, outer ports 15 symmetrically opened on both sides of the switching sleeve column 9, and the outer ports 15 are communicated with the intermediate cavity 14. An intermediate shaft 10 is fixedly sleeved inside the switching sleeve column 9. An internal cavity is provided inside the switching sleeve column 9, and a magnetic force vibration component 19 is fixedly provided in the internal cavity. The cleaning component 17 is located in the through adaptation groove 12. A suction pump 20 is fixedly provided at the top of the spraying cylinder 5. The suction end of the suction pump 20 is communicated with the inside of the spraying cylinder 5. The other end of the spraying cylinder 5 is fixedly communicated with a suction pipe 21. When the cleaning component 17 rotates to the upper side, it adsorbs the treatment agent in the air inhaled through the suction pipe 21.

[0036] Embodiment 1: During use, as the liquid pump on the storage tank pumps the treatment agent into the distribution cavity 22 and inputs it into the spraying cylinder 5 through the communication pipeline 6 and the liquid inlet hole 8, keep the driving mechanism 11 started to drive the intermediate shaft 10 to rotate, so that the multi-condition switching component rotates in the spraying cylinder 5 and the switching sleeve column 9 rotates.

[0037] When the communication cavity 13 rotates to the lower side, the fed treatment agent directly sprays the treatment agent downward along the bottom spraying holes 7 and acts on the sewage pool. And during the rotation process, the outer port 15 corresponding to one side of the intermediate cavity 14 rotates and approaches the spraying hole 7, and the spraying hole 7 on one side of the bottom spraying hole 7 is gradually blocked by the outer side surface of the switching sleeve column 9, and the number of spraying holes of the bottom spraying hole 7 decreases. The spraying pressure of the unblocked and sealed spraying holes 7 increases and is sprayed into the sewage pool. And during the continuous rotation process, the outer port 15 is communicated with the bottom spraying hole 7. At this time, the left spraying holes 7 and the right spraying holes 7 at the bottom of the spraying cylinder 5 spray synchronously, while the middle spraying holes 7 are sealed. When the outer port 15 conducts the spraying holes 7 distributed in an arc shape at the bottom column by column, a state of independent spraying of a single column of spraying holes 7 at the bottom of the spraying cylinder 5 appears, and the treatment liquid is further sprayed into the sewage. And during the rotation process, different directions of independent spraying are continuously switched.

[0038] When the through - fitting slot 12 rotates to the lower part and is in communication with the spraying hole 7, and the cleaning assembly 17 gradually rotates above the spraying hole 7, the input treatment agent is filtered by each arc - shaped cleaning brush 172 and sprayed out along the spraying hole 7. And during the rotation process, the arc - shaped cleaning brush 172 rubs against the spraying hole 7 on the inner wall of the spraying cylinder 5 to complete the blockage cleaning. At the same time, the magnetic - powered vibration assembly 19 is started. The electromagnet 196 is started intermittently. When the electromagnet 196 is started, it is energized to generate a magnetic attraction force, and at the same time, it generates a repulsive force on the magnetic ring 193 of the same magnetic pole, pushing the sleeve 191 to slide along the middle shaft 10. While compressing the second spring 195, the convex block 192 pushes the movable rod 173 of the cleaning assembly 17, so that the movable rod 173 reciprocally compresses the first spring 175, and synchronously drives the arc - shaped plate 171 to vibrate reciprocally, so that the rotating arc - shaped cleaning brush 172 performs blockage cleaning on the spraying hole 7 at the inner wall of the spraying cylinder 5 in a reciprocally vibrating state.

[0039] First, the driving mechanism 11 drives the slow rotation of the multi - working - condition switching assembly. Cooperating with the multi - working - condition switching assembly rotating in the spraying cylinder 5 and the treatment agent input into the spraying cylinder 5, on the one hand, during the rotation process, it cooperates with the cleaning assembly 17 in the multi - working - condition switching assembly, intermittently rubs the inner end of the spraying hole 7 during the rotation process, and during the relative rubbing period of the rotation, the magnetic - powered vibration assembly 19 is used to control the cleaning assembly 17 to perform impact treatment at the inner end of the spraying hole 7, so as to realize self - blockage cleaning during the spraying process, avoid the solid particles in the mixed treatment agent from blocking the spraying hole 7, and complete the self - blockage cleaning treatment of the spraying hole 7 by using the intermittent friction and reciprocating impact under dynamic rotation. And the self - blockage cleaning and the spraying treatment occur simultaneously, without the need for shutdown treatment, with high spraying efficiency and good blockage cleaning effect.

[0040] In addition, by using the rotation of the switching sleeve column 9 in the multi - working - condition switching assembly again, during the rotation of the communication cavity 13, the middle cavity 14 and the through - fitting slot 12, the communication cavity 13 is directly in communication with the spraying hole 7 after rotation for spraying operation, and the middle cavity 14 and the outer port 15 are gradually in communication with the spraying hole 7 during the rotation process, realizing the dynamic adjustment of the spraying hole 7, realizing the reduction of the spraying quantity of the spraying hole 7 and the change of the independent spraying angle. The former enhances the outlet pressure of the spraying hole 7 while reducing the number of spraying holes, improving the ability of the treatment agent to be sprayed into the sewage. The latter realizes the enhanced spraying treatment in different angular directions. During the spraying process of the actual sewage treatment agent above the water surface, it has spraying intensity adjustment and angle socketing, enhancing the ability of the treatment agent to be sprayed into the sewage, improving the sewage treatment effect, and during the rotation of the switching sleeve column 9, the multi - working - condition spraying treatments such as full - open spraying, enhanced spraying and self - cleaning spraying are intermittently completed, and the actual spraying effect is good.

[0041] Embodiment 2: When spraying, the suction pump 20 is started. When the through-adaptation groove 12 rotates to the upper side, the suction pump 20 sucks the air in the suction pipe 21 through the through-adaptation groove 12, so that the suction pipe 21 sucks the wet air containing the treatment agent atomized and dispersed in the air towards the spraying area. The wet air is sucked into the through-adaptation groove 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. When the arc-shaped cleaning brush 172 rotates to the lower side 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 is remixed and sprayed out.

[0042] When the pumping of the treatment agent is stopped and the through-adaptation groove 12 is kept stationary above, the wet air mixed with the treatment agent in the environment is sucked into the through-adaptation groove 12, and the dispersed treatment agent is adsorbed in the cleaning assembly 17, completing the environmental treatment.

[0043] First, by utilizing the rotation of the multi-condition switching assembly again, in cooperation with the position adjustment of the through-adaptation groove 12 and the cleaning assembly 17, and by using the added suction pump 20 and suction pipe 21, when the through-adaptation groove 12 rotates to the upper side, the conduction with the suction pump 20 and the suction pipe 21 is realized, so that the wet air after spraying in the environment is sucked into the through-adaptation groove 12, and the residual dispersed treatment agent in the mixed wet air is sucked into the through-adaptation groove 12 and adsorbed in the multi-group distributed cleaning assemblies 17. By using the brush-shaped arc-shaped cleaning brushes 172 densely arranged in the cleaning assembly 17, while allowing air to pass through the gaps, the treatment agent in the passing wet air is adsorbed and collected in a wet state, realizing the treatment of environmental air, improving the air quality after the top spraying treatment of sewage, and avoiding the pollution of the environment by the dispersed treatment agent in the mixed wet air.

[0044] In addition, by utilizing the adsorption and collection ability of the cleaning assembly 17 again, when the multi-condition switching assembly rotates to the lower side, the cleaning assembly 17 adsorbed with the treatment agent is below, and under the flushing of the introduced treatment agent liquid, the collected treatment agent is remixed in the treatment agent liquid and directly sprayed out along the spraying hole 7 where it is located, realizing the secondary spraying after the recovery of the adsorbed and collected treatment agent. There is no need to perform additional treatment on the adsorbed and collected treatment agent, and the subsequent reuse is directly completed, with good use effect.

When the outer side port 15 conducts the spraying holes 7 distributed in an arc along the bottom column by column, it presents a state where the single-row spraying holes 7 at the bottom of the spraying cylinder 5 spray independently, further spraying the treatment liquid into the sewage, and continuously switching independent spraying in different directions during the rotation process. When the through-fitting groove 12 rotates to the lower side and is conducted with the spraying hole 7, and the cleaning component 17 gradually rotates above the spraying hole 7, the fed treatment agent is filtered by each arc-shaped cleaning brush 172 and sprayed out along the spraying hole 7. And during the rotation process, the arc-shaped cleaning brush 172 rubs the spraying hole 7 at the inner wall of the spraying cylinder 5 to complete blockage cleaning. At the same time, start the magnetic force vibration component 19, the electromagnet 196 starts intermittently, and when the electromagnet 196 starts, it is energized to generate a magnetic suction force, and generates a repulsive force on the magnetic ring 193 of the same magnetic pole, pushing the sleeve 191 to slide along the intermediate shaft 10, compressing the second spring 195, and at the same time, the convex block 192 pushes the movable rod 173 of the cleaning component 17, so that the movable rod 173 reciprocally compresses the first spring 175, and synchronously drives the arc-shaped plate 171 to vibrate reciprocally, so that the rotating arc-shaped cleaning brush 172 clears the blockage of the spraying hole 7 at the inner wall of the spraying cylinder 5 in a reciprocally vibrating state;

[0060] When spraying, the suction pump 20 is started. When the through - adaptation groove 12 rotates to the upper side, the suction pump 20 sucks the air in the suction pipe 21 through the through - adaptation groove 12, so that the suction pipe 21 sucks the wet air containing the treatment agent atomized and dispersed in the air towards the spraying area. The wet air is sucked into the through - adaptation groove 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. When the arc - shaped cleaning brush 172 rotates to the lower side 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 is remixed and sprayed out. When the pumping of the treatment agent stops and the through - adaptation groove 12 remains stationary above, the wet air mixed with the treatment agent in the environment is sucked into the through - adaptation groove 12, and the dispersed treatment agent is adsorbed in the cleaning assembly 17, completing the environmental treatment.

The scope of the present invention is defined by the appended claims and their equivalents.
