Description

Technical Field

[0001] This invention relates to the field of chemical wastewater purification and treatment technology, specifically to an intelligent chemical wastewater purification and treatment device. Background Technology

[0002] In the complex and crucial process of wastewater purification, the addition of various catalytic powders is a critical step. These wastewaters come from a wide range of sources and have complex compositions, containing various organic pollutants that are difficult to degrade, heavy metal ions, and suspended particles. If they are discharged directly without effective treatment, they will pose a serious threat to the environment and human health. Catalytic powders can purify wastewater more efficiently.

[0003] However, existing technologies rely solely on surface-level spraying of catalytic powder, allowing it to gradually enter the wastewater by gravity. This results in insufficient contact between the catalytic powder and different layers of the wastewater. The powder settles slowly, with the upper wastewater contacting the catalytic powder relatively early, while the lower wastewater requires a longer time to reach it. The catalytic powder cannot be evenly distributed throughout the wastewater system and cannot function effectively in a timely manner. The precipitation reaction cannot fully proceed in a short time, significantly prolonging the time required for precipitation and leading to low wastewater purification efficiency. Furthermore, existing chemical wastewater contacts the catalytic powder at room temperature, resulting in low catalytic efficiency and a large amount of unreacted catalytic powder residue. Discharge into the environment may cause secondary pollution. Additionally, direct discharge of chemical wastewater into treatment tanks or containers causes a large amount of impurities and metal particles to precipitate inside, leading to complicated subsequent treatment processes. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems existing in the prior art, and to propose an intelligent chemical wastewater purification and treatment equipment.

A stirring plate is welded and fixed on the surface of the connecting shaft.

[0007] In the aforementioned intelligent chemical wastewater purification equipment, the powder spraying component includes a catalytic powder box fixed below the surface of the wastewater purification tank. The catalytic powder box is transparent to facilitate observation and addition of catalytic powder. Meanwhile, a powder suction pipe extends from inside the catalytic powder box and is connected to one end of a powder suction pump. The other end of the powder suction pump is equipped with a powder outlet pipe, and one end of the powder outlet pipe is matched with the components in the filter powder spraying structure.

[0008] In the aforementioned intelligent chemical wastewater purification equipment, the filter powder spraying structure includes a conveying powder spraying component that is fixedly installed on the filter component. The conveying powder spraying component includes a hollow disc with mounting holes. The surface of the hollow disc is provided with a conveying hole that is connected to the mounting holes. A conveying pipe is installed on the surface of the hollow disc through the mounting holes. A powder conveying hole that is connected to the conveying hole is provided on the lower surface of one end of the conveying pipe. A flexible baffle that shields the powder conveying hole is fixedly installed inside the conveying pipe.

[0009] In the above-mentioned intelligent chemical wastewater purification equipment, the conveying hole is installed and connected to one end of the conveying connecting pipe, and the conveying connecting pipe is distributed in a ring array around the surface of the hollow disk. At the same time, the other end of the conveying connecting pipe is embedded and connected to a concave ring with a hollow structure inside. The surface of the concave ring is provided with another mounting hole that is matched and connected to the powder outlet pipe.

[0010] In the aforementioned intelligent chemical wastewater purification equipment, one end of the conveying pipe is installed with the matching end cap through a through hole, and the number of through holes and the conveying pipe are the same. At the same time, the conveying pipe and the through hole are arranged symmetrically along the axis.

[0011] In the aforementioned intelligent chemical wastewater purification equipment, the filter component includes a water receiving hopper with a hollow, through-hole structure. A through-hole is provided at the bottom of the water receiving hopper to connect with the upper part of the conveying pipe. A support column is fixed inside the water receiving hopper to support the through-hole plate. A guide sliding groove is symmetrically provided on the surface of the through-hole plate, and a connecting spring is fixedly installed at one end of the guide sliding groove. The connecting spring is coated with an anti-corrosion coating to prevent corrosion caused by prolonged contact with the chemical wastewater.

[0012] In the aforementioned intelligent chemical wastewater purification equipment, the other end of the connecting spring is fixedly installed on one side of the guide slide block, and a matching connecting hole is provided on the top of the guide slide block. At the same time, a through hole recess is fixedly installed on the other side of the guide slide block. A through hole connecting plate is rotatably installed on the through hole recess through a connecting pin, and another through hole recess is fixedly installed on one end of the through hole connecting plate. Meanwhile, multiple rotating connecting plates are rotatably installed on the other through hole recess through a connecting pin.

[0013] In the aforementioned intelligent chemical wastewater purification equipment, one end of the multi-section rotating connecting plate is rotatably connected to the through-hole recess, and a matching connecting hole is opened on one side of the surface of the multi-section rotating connecting plate. At the same time, the through-hole recess is tilted and fixed above the inside of the water receiving hopper.

[0014] In the aforementioned intelligent chemical wastewater purification equipment, multiple rotating connecting plates and guide sliding blocks are equipped with filter screens through matching connecting holes and connecting rods. The filter screens are made of flexible and resilient materials to prevent damage during frequent pulling.

[0015] Compared with the prior art, the advantages of the present invention are as follows: The conveying and powder spraying assembly in this invention extracts and conveys the catalytic powder into the concave ring, and then sprays the catalytic powder in a ring shape into the inside of the conveying pipe, so as to make full contact with the chemical wastewater passing through the conveying pipe. This avoids the catalytic powder only contacting the surface of the chemical wastewater to participate in the reaction. At the same time, when the catalytic powder and the chemical wastewater in the conveying process are fully mixed and contacted, the catalytic powder can fully participate in the chemical reaction to purify the chemical wastewater. The heating plate and stirring plate in this invention, through the synchronous operation of the stirring plate and the heating plate, allow for a secondary and thorough mixing of the catalytic powder and the chemical wastewater, ensuring that the chemical wastewater and the catalytic powder are fully mixed. At the same time, the heating plate can effectively improve the chemical activity of the catalytic powder, accelerate the chemical reaction, shorten the reaction time, and improve the purification efficiency. The filter assembly in this invention, when in contact with chemical wastewater through the filter screen, the impact force of the water flow causes the filter screen to push the guide slide block to move synchronously. At this time, the filter screen contracts inward to filter impurities and particles in the wastewater. After the wastewater is filtered, the filter screen recovers its elasticity due to the influence of elastic recovery. At this time, the particles and impurities stuck in the filter holes during the filtration process are bounced up, thus avoiding the filter screen from becoming clogged and affecting the filtration speed and efficiency. The protrusion and discharge pipe provided in this invention allow the wastewater purification tank to be in a closed or open state by controlling the opening and closing of the discharge pipe, so as to purify and discharge chemical wastewater. Furthermore, the multiple discharge pipes can be set up simultaneously to improve the discharge speed and efficiency, and avoid the situation of low discharge speed and efficiency when a single pipe is used for discharge. At the same time, it can also effectively avoid the continuous water flow impact when a single pipe is used for discharge. Attached Figure Description

At the same time, the conveying pipe 2013 and the through hole 1018 are arranged symmetrically along the axis.

[0038] When the powder suction pump 1023 is working, it delivers the catalytic powder into the concave ring 2017. The catalytic powder inside the concave ring 2017 is then transported through the conveying connection pipe 2016 to the conveying pipe 2013. The catalytic powder is carried by the flowing water into the wastewater purification tank 1011 for preliminary mixing. The pre-mixed wastewater undergoes chemical purification reaction under the combined action of the heating plate 1015 and the stirring plate 10112.

The sample is provided with matching connection holes 2026, and the through hole recess 2027 is inclinedly fixed inside the upper part of the water receiving hopper 2021. The multi-section rotating connecting plate 2029 and the guide sliding block 2025 are equipped with filter screens 20211 through matching connection holes 2026 and matching connecting rods 20210. The filter screens 20211 are made of filter screens with good flexibility and toughness to avoid damage to the filter screens 20211 during frequent pulling. At the same time, when the filter screens 20211 are impacted by different water flows, the pore size of the filter screens 20211 will not change with the deformation of the filter screens 20211, thus ensuring uniform filtration of impurities.

[0041] During the purification of chemical wastewater, the wastewater is diverted through a pipeline into the receiving hopper 2021. When the filter screen 20211 comes into contact with a large area of ​​water flow, it pushes the guide slide block 2025 to move, causing the filter screen 20211 to retract inward. When the filter screen 20211 comes into contact with a small area of ​​water flow, the connecting spring 2024 drives the guide slide block 2025 and the filter screen 20211 to move synchronously. During the elastic recovery process, the filter screen 20211 concentrates residual impurities and particles on its surface for easy collection and treatment, while preventing the filter screen 20211 from clogging easily. When the filter screen 20211 needs to be replaced, the matching connecting rod 20210 is pulled apart from the matching connecting hole 2026 to quickly replace the filter screen 20211.
