Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater pump with ozone purification. Background Technology

[0002] A wastewater pump with ozone purification is a composite device that combines the centrifugal pump's conveying function with ozone oxidation technology. Its core structure includes the wastewater pump body, an ozone generator, and a mixing reaction unit. The working principle is based on the centrifugal force of the impeller conveying wastewater while a dynamic mixing device, such as a spiral turbulence or atomizing nozzle, ensures that ozone and wastewater come into full contact. The strong oxidizing properties of ozone are used to efficiently degrade organic matter, kill pathogens, and decolorize and deodorize. This type of equipment is suitable for industrial wastewater, municipal sewage, and aquaculture, and can reduce dependence on chemical agents and improve water quality.

[0003] In wastewater environments, factors such as natural input and anthropogenic discharge result in the widespread presence of suspended solids. When wastewater carrying these suspended solids enters an ozone purification device for treatment, the suspended solids, due to their own charge characteristics and porous structure, readily accumulate organic toxins or heavy metal pollutants from the wastewater on their surface or inside through physical and chemical adsorption. This adsorption phenomenon can lead to a series of adverse consequences. On the one hand, the adsorbed pollutants are tightly wrapped on the surface or inside of the suspended solids, forming a dense barrier. This barrier acts like a "protective wall," severely hindering the effective contact between ozone molecules and target pollutants, making it difficult for ozone to fully exert its oxidizing effect, thus significantly reducing the purification effect. On the other hand, the organic components adsorbed by the suspended solids can also undergo competitive oxidation reactions with ozone. In this process, a large amount of effective ozone is consumed, further reducing the oxidation efficiency of ozone and hindering the wastewater purification process. Therefore, we propose a wastewater pump with ozone purification. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that suspended solids, due to their own charge characteristics and porous structure, can easily accumulate organic toxins or heavy metal pollutants in wastewater on their own surface or inside through physical adsorption and chemical adsorption.

[0015] The present invention has at least the following beneficial effects:

[0016] 1. During the wastewater purification process, the drive frame rotates the cutting mesh to cut and break up the suspended solids aggregated in the wastewater discharged from the discharge tank, thereby improving the ozone purification effect. The aggregated suspended solids in the wastewater form large particles or clumps. These clumps contain a large amount of organic matter and microorganisms, making it difficult for ozone to penetrate into the interior for oxidation and decomposition. At the same time, the rotating cutting mesh cuts and breaks up the suspended solids into smaller particles, increasing the specific surface area of ​​the suspended solids. This allows ozone to come into more complete contact with the suspended solids, thereby improving the efficiency of oxidation and decomposition. Furthermore, the aggregated suspended solids in the wastewater are prone to accumulate in the discharge tank or subsequent treatment equipment, causing equipment blockage, affecting purification efficiency, and even causing equipment damage. The rotating cutting mesh can effectively prevent the accumulation of large suspended solids and keep the discharge tank and subsequent treatment equipment unobstructed.

[0017] 2. After the wastewater oxidation treatment is completed, a constantly rotating filter screen is used to filter and separate suspended solids in the wastewater to be discharged. The constantly rotating filter screen can form a dynamic filtration mechanism. Compared with a static filter screen, the wastewater has more contact with the filter screen during rotation, and suspended solids are more easily intercepted and attached to the filter screen, thereby improving filtration efficiency. Through efficient filtration and separation of suspended solids, the rotating filter screen can reduce the discharge of pollutants in wastewater and reduce secondary pollution to the environment.

[0029] 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.

[0030] Example 1: Please refer to Figures 1-9 This invention provides a technical solution: a sewage pump with ozone purification, comprising a mounting platform 1, a pump body 2, and a purification cylinder 3. Multiple guide plates 4 are evenly distributed circumferentially within the purification cylinder 3; strip-shaped discharge channels 5 are formed on the guide plates 4; multiple frames 6 are circumferentially arranged below the guide plates 4; cutting mesh 7 is provided on the frames 6; a purification unit 8 connected to the frames 6 is provided inside the purification cylinder 3, used to drive the frames 6 to rotate the cutting mesh 7 during sewage purification, thereby cutting and breaking up suspended solids aggregated in the sewage discharged from the discharge channels 5; an impurity separation unit 13 is provided inside the purification cylinder 3, used to filter and collect the broken suspended solids in the sewage.

[0031] The purification unit 8 includes a flow guide 9 disposed inside the purification cylinder 3 for guiding sewage to be discharged along a preset path; a crusher 10 is disposed inside the purification cylinder 3 for driving the frame 6 to rotate the cutting mesh 7 to cut and crush the aggregated suspended solids in the sewage discharged from the discharge trough 5; an absorber 11 is disposed on the frame 6 for adsorbing and cleaning the attached grease and emulsified substances during the cutting process of the cutting mesh 7; and a purification element 12 is disposed inside the purification cylinder 3 for introducing ozone into the sewage to complete oxidation purification.

[0032] The flow guide 9 includes a flow pipe 91 disposed on the pump body 2, and a connecting pipe 92 that works with the flow pipe 91 is disposed inside the purification cylinder 3, and the connecting pipe 92 is connected to the flow pipe 91.

[0033] When the pump body 2 is working, the sewage is discharged into the connecting pipe 92 through the diversion pipe 91, and then transported to each guide plate 4 through the connecting pipe 92. Finally, it is discharged into the crushing chamber 101 through the guide plate 4. The design of the strip discharge channel 5 makes the contact area between the sewage and the cutting mesh 7 larger after the sewage is discharged into the crushing chamber 101, and at the same time the thickness of the water flow is smaller, thereby reducing the reaction force generated on the cutting mesh 7 and reducing the wear on the cutting mesh 7.

[0034] The design of the strip discharge channel 5 increases the contact area between the wastewater and the cutting mesh 7 after it enters the crushing chamber 101. This helps the suspended solids in the wastewater to come into fuller contact with the cutting mesh 7, thereby improving cutting efficiency and ensuring that the suspended solids are broken up more effectively. At the same time, the strip discharge channel 5 reduces the thickness of the water flow, forming a more uniform and thinner water flow layer, which is conducive to the cutting mesh 7 to cut the suspended solids more finely and improve the cutting effect. By increasing the contact area between the wastewater and the cutting mesh 7 and reducing the thickness of the water flow, the design of the strip discharge channel 5 effectively reduces the reaction force of the wastewater on the cutting mesh 7. This helps to reduce the impact and wear on the cutting mesh 7 and extend its service life. In addition, the strip discharge channel 5 ensures that the wastewater is evenly distributed in the crushing chamber 101, avoiding situations where the local water flow is too large or too small, which helps to maintain the stable operation of the system.

[0035] The crushing component 10 includes a crushing chamber 101 disposed inside the purification cylinder 3. The connecting pipe 92 passes through the crushing chamber 101, and the guide plate 4 is located inside the crushing chamber 101. A power shaft 102 is rotatably disposed at the bottom of the connecting pipe 92. One end of the power shaft 102 is connected to a motor. A mounting base 103 is disposed on the power shaft 102. The mounting base 103 is connected to the frame 6. An air jet pipe 104 is disposed on the frame 6. The air jet pipe 104 is connected to an ozone generator through a pipe. Multiple air jet holes 105 are opened on the air jet pipe 104.

[0036] When sewage is discharged from the discharge tank 5, the power shaft 102 operates under the drive of the motor. The operation of the power shaft 102 drives the mounting base 103 mounted on it to rotate. The rotation of the mounting base 103 drives multiple frames 6 and the cutting mesh 7 mounted on the frames 6 to rotate. During the rotation, the cutting mesh 7 comes into contact with the sewage and impacts the sewage to achieve the effect of cutting the aggregated suspended solids in the sewage. When the cutting is completed, the jet pipe 104 and jet hole 105 located on the other side of the cutting mesh 7 will spray ozone gas to further break up the suspended solids in the sewage. At the same time, the ozone comes into initial contact with the sewage to perform preliminary purification of the sewage.

[0037] The motor-driven power shaft 102 rotates the mounting base 103, frame 6, and cutting mesh 7. The cutting mesh 7 rotates at high speed in the sewage and generates impact force. This dynamic cutting method can fully contact the aggregated suspended solids in the sewage and cut them from multiple directions, effectively reducing the particle size of the suspended solids. This breaks down the originally larger suspended solids into smaller particles, making it easier for them to be further removed in subsequent treatment stages, thus improving the efficiency and quality of sewage treatment. After the initial cutting, the jet pipe 104 releases ozone through the jet hole 105. The ozone gas uses its impact force and oxidizing properties to further break down the suspended solids. Ozone gas has strong oxidizing properties and a certain impact force, which can further destroy the structure of the suspended solids, making them finer. This dual breaking mechanism greatly enhances the treatment effect of suspended solids and significantly reduces the content of suspended solids in sewage. While breaking down suspended solids, ozone gas also makes initial contact with the sewage and undergoes an oxidation reaction. Ozone can oxidize organic matter, reducing substances, and some harmful microorganisms in the sewage, decomposing them into harmless or low-toxic substances, thereby reducing the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of the sewage, and performing preliminary purification of the sewage, reducing the burden on subsequent sewage treatment processes.

[0038] The absorber 11 includes a sliding rod 111 and a reciprocating screw 112 disposed at both ends of the frame 6. One end of the reciprocating screw 112 passes through the frame 6 and is rotatably connected to the frame 6. The sliding rod 111, the reciprocating screw 112, and the air jet pipe 104 are respectively located on both sides of the cutting mesh 7. A connecting block 113 is provided on both the sliding rod 111 and the reciprocating screw 112. The connecting block 113 is slidably connected to the sliding rod 111 and threadedly connected to the reciprocating screw 112. A movable chamber 114 is provided on the 113, and an adsorption roller 115 is rotatably arranged inside the movable chamber 114. The adsorption roller 115 is in contact with the cutting mesh 7. A scraper 116 is provided inside the movable chamber 114 and contacts the adsorption roller 115. A drive gear 117 is provided at one end of the reciprocating screw 112 located outside the frame 6. An annular plate 118 is provided on the bottom of the connecting pipe 92. A drive tooth groove 119 that meshes with the drive gear 117 is opened on the annular plate 118.

[0039] When the frame 6 rotates, it drives the reciprocating screw 112 mounted on it to rotate synchronously around the power shaft 102. At the same time, the reciprocating screw 112 rotates synchronously, driving the drive gear 117 mounted at its end to rotate synchronously. When the drive gear 117 rotates, it meshes with the drive tooth groove 119 opened on the annular plate 118 and rotates under the push of the drive tooth groove 119. The rotation of the drive gear 117 drives the reciprocating screw 112 connected to it to rotate. The rotation of the reciprocating screw 112 drives the movable chamber 114 threadedly connected to it to move up and down reciprocally. When the movable chamber 114 moves, it drives the adsorption roller 115 mounted on it to absorb the grease and emulsion on the cutting screen 7. When the movable chamber 114 moves, the adsorption roller 115 is pushed by the cutting screen 7 to rotate and contacts the scraper 116 during the rotation process, separating the attached substances from the adsorption roller 115.

[0040] The frame 6 rotates, driving the reciprocating screw 112 to rotate around the power shaft 102. This, in turn, through a series of transmissions, causes the moving chamber 114 to drive the adsorption roller 115 to move up and down reciprocally. This dynamic movement allows the adsorption roller 115 to fully and meticulously contact the cutting mesh 7, effectively absorbing the grease and emulsified substances adhering to the cutting mesh 7. This effectively prevents these substances from accumulating on the cutting mesh 7, keeping it clean and ensuring that the cutting mesh 7 always maintains good cutting performance and maintains the cutting effect on suspended solids in sewage. The entire cleaning process is completed automatically by mechanical transmission, eliminating the need for frequent manual cleaning of the cutting mesh 7. This not only reduces the intensity of manual labor but also reduces the risk of incomplete cleaning or damage to the equipment due to manual operation, improving the stability and reliability of equipment operation. Furthermore, through the continuous cleaning of the adsorption roller 115 by the scraper 116, the adsorption roller 115 can always maintain a good working condition without frequent shutdowns for replacement or deep cleaning. This helps improve the continuous operation capability of the entire sewage treatment system, reduces downtime caused by equipment maintenance, and improves sewage treatment efficiency.

[0041] The purification component 12 includes an aeration chamber 121 disposed within the crushing chamber 101. The top surface of the aeration chamber 121 has multiple inlets 122 communicating with the crushing chamber 101. A connecting shaft 123 is rotatably mounted inside the aeration chamber 121. One end of the connecting shaft 123 passes through the aeration chamber 121 and is connected to the power shaft 102. An air supply chamber 124 is mounted on the connecting shaft 123. Multiple aeration plates 125 are mounted on the air supply chamber 124. The aeration plates 125 are hollow and communicate with the air supply chamber 124. Aeration holes 126 are provided on the aeration plates 125. Multiple air collection grooves 127 are provided on the side wall of the crushing chamber 101. An aeration chamber 121 is provided, and a connecting pipe 128 is provided inside the aeration chamber 121, which is connected to the air collection trough 127. An air collection chamber 129 is provided inside the aeration chamber 121 and connected to the connecting pipe 128. The air collection chamber 129 is connected to the air supply chamber 124 and is rotatably connected to the air supply chamber 124. A guide pipe 1211 is provided inside the aeration chamber 121. One end of the guide pipe 1211 passes through the aeration chamber 121 and the crushing chamber 101. A delayed contact chamber 1210 is provided at the other end of the guide pipe 1211 outside the crushing chamber 101. Multiple delayed contact chambers 1210 are provided and are interconnected.

[0042] The treated wastewater falls into the crushing chamber 101 under gravity and enters the aeration chamber 121 through the inlet 122. Since the drainage efficiency of the inlet 122 is less than the inlet efficiency of the discharge trough 5, the wastewater will accumulate at the bottom of the crushing chamber 101, thus sealing the inlet 122. At this time, the ozone gas ejected from the jet hole 105 enters the gas collection chamber 129 under pressure through the gas collection trough 127 and the connecting pipe 128, and then enters the aeration plate 125 through the gas collection chamber 129 and the gas supply chamber 124. Finally, it is discharged into the wastewater in the aeration chamber 121 through the aeration plate 125 to further purify the wastewater. At the same time, the liquid in the aeration chamber 121 mixes with the ozone after contacting it and is discharged into the delayed contact chamber 1210 through the guide pipe 1211, thereby increasing the contact time between the ozone and the liquid and further improving the purification effect of ozone on wastewater.

[0043] Because the drainage efficiency of inlet 122 is less than the inlet efficiency of discharge trough 5, the sewage accumulates at the bottom of crushing chamber 101, sealing inlet 122. This allows the ozone gas ejected from jet nozzle 105 to flow more smoothly through gas collection trough 127 and connecting pipe 128 into gas collection chamber 129 under pressure, then through gas supply chamber 124 to aeration plate 125, and finally into sewage in aeration chamber 121. This pressure-driven ozone delivery method increases the solubility of ozone in sewage, allowing ozone to come into more complete contact with pollutants in the sewage. The ozone effectively oxidizes and decomposes organic matter, bacteria, viruses and other harmful substances in wastewater, significantly improving the wastewater purification effect. After the liquid in the aeration chamber 121 comes into contact with ozone, it mixes with ozone and is discharged into the delayed contact chamber 1210 through the guide pipe 1211. The delayed contact chamber 1210 provides additional contact space and time for wastewater and ozone, allowing ozone to exert its oxidizing effect more fully, further removing recalcitrant organic matter and residual pollutants in wastewater, ensuring that wastewater is purified more thoroughly, improving the effluent quality and making it more compliant with discharge standards or subsequent treatment requirements.

[0044] The impurity separation unit 13 includes a filter element 14 disposed inside the purification cylinder 3. The filter element 14 is used to filter and separate suspended solids in the purified wastewater. A drive element 15 is disposed on the filter element 14 to provide power for the operation of the filter element 14.

[0045] The filter element 14 includes a drain pipe 141 disposed on the delayed contact chamber 1210. A vertical rod 142 is disposed at the bottom of the purification cylinder 3. A filter chamber 143 is disposed on the vertical rod 142. The filter chamber 143 is designed to be inclined and is located below the drain outlet of the drain pipe 141. A rotating shaft 144 is rotatably disposed inside the filter chamber 143. A rotating belt 145 is disposed on the rotating shaft 144. A filter screen 146 is disposed on the rotating shaft 144 and connected to the rotating belt 145. A collection chamber 147 is disposed on the filter chamber 143. A peeling plate 148 is disposed inside the collection chamber 147 and contacts the filter screen 146. A discharge pipe 149 is disposed on the filter chamber 143.

[0046] The driving component 15 includes a drive shaft 151 rotatably disposed inside the drain pipe 141. A plurality of push plates 152 are disposed at one end of the drive shaft 151 located inside the drain pipe 141. A transmission shaft 153 connected to a rotating shaft 144 is rotatably disposed on the filter chamber 143. A power pulley 154 is disposed at one end of the transmission shaft 153 and the drive shaft 151 located outside the drain pipe 141. A power belt 155 is disposed on the power pulley 154.

[0047] After the sewage flows through multiple delayed contact chambers 1210, it is discharged into the filter chamber 143 through the drain pipe 141. It first comes into contact with the filter screen 146 in the filter chamber 143. Under the interception of the filter screen 146, the purified liquid is discharged from the purification cylinder 3 through the discharge pipe 149, while the suspended solids are left on the filter screen 146. When the sewage flows through the drain pipe 141, the water flow will impact the push plate 152, thereby driving the push plate 152 to rotate. The rotation of the push plate 152 drives the drive shaft 151 to rotate, the drive shaft 151 drives the power pulley 154 to rotate, and through the power belt 155 drives the transmission shaft 153 and the rotating shaft 144 connected to the transmission shaft 153 to rotate. The rotation of the rotating shaft 144 drives the rotating belt 145 and the filter screen 146 connected to the rotating belt 145 to rotate. When the filter screen 146 rotates, the peeling plate 148 scrapes off the suspended solids trapped on its surface and discharges them into the collection chamber 147, thereby avoiding the accumulation of suspended solids and affecting the filtration effect of the filter screen 146.

[0048] After further purification through multiple delayed contact chambers 1210, the wastewater enters the filter chamber 143, where it first contacts the filter screen 146. The filter screen 146 effectively intercepts residual suspended solids in the pre-treated liquid, ensuring that the purified liquid reaches a high purity when discharged from the purification cylinder 3 through the discharge pipe 149. This significantly improves the final quality of wastewater treatment, making the effluent quality more consistently meet discharge standards or subsequent usage requirements. When the wastewater flows through the drain pipe 141, the water flow impacts and pushes the plate 152 to rotate, which in turn drives a series of transmission devices to rotate the filter screen 146. During the rotation, the peeling plate 148 promptly scrapes off the suspended solids trapped on the surface of the filter screen 146 and discharges them into the collection chamber 147. This automatic cleaning mechanism effectively prevents suspended solids from accumulating on the filter screen 146, preventing the filter screen 146 from becoming clogged and causing a decrease in filtration efficiency or a deterioration in filtration effect, thus ensuring that the filter screen 146 can continuously and efficiently perform its filtration function.

[0049] Example 2: Please refer to Figure 10This invention provides a technical solution: a cleaning brush 16 is provided inside the collection chamber 147. The cleaning brush 16 contacts the filter screen 146. Multiple filter holes 17 are provided on one side of the collection chamber 147. When the filter screen 146 rotates, the cleaning brush 16 in contact with the filter screen 146 can thoroughly scrub the surface of the filter screen 146. Compared to simply relying on the peeling plate 148 to scrape off suspended matter, the cleaning brush 16 can penetrate deep into the mesh and gaps of the filter screen 146, thoroughly removing fine suspended matter, impurities, and potential dirt adhering to the filter screen 146. This effectively prevents the filter screen 146 from clogging due to long-term use, ensuring that the filter screen 146 always maintains good filtration performance. The continuous contact between the cleaning brush 16 and the filter screen 146 ensures that the filter screen 146 rotates... During the process, each area passing through the cleaning brush 16 is cleaned in a timely manner. This real-time and efficient cleaning method avoids excessive accumulation of suspended matter on the filter screen 146, reduces the increased cleaning difficulty caused by accumulation, improves the overall cleaning efficiency of the filter screen 146, and ensures the continuity and stability of the sewage filtration process. The multiple filter holes 17 opened on one side of the collection chamber 147 allow the liquid in the suspended matter scraped off the filter screen 146 by the cleaning brush 16 to be discharged through the filter holes 17 after entering the collection chamber 147. In this way, the collection chamber 147 mainly collects solid suspended matter, realizing effective solid-liquid separation, which facilitates the subsequent centralized treatment and disposal of solid suspended matter, and improves the utilization efficiency and practicality of the collection chamber 147.
