Description

Technical Field

[0001] This invention relates to the field of water pollution control technology, specifically to a wastewater purification and treatment device for water pollution control. Background Technology

[0002] With the acceleration of industrialization and urbanization, water pollution has become increasingly serious. Wastewater discharge has a wide range of sources, including industrial wastewater, domestic sewage and agricultural non-point source pollution, which has led to serious pollution of surface water and groundwater, posing a huge threat to the ecological environment, human health and economic development. Wastewater contains different types of impurities, which need to be physically treated first. Traditional wastewater treatment equipment, such as screens, grit chambers, and sedimentation tanks, is not precise enough in separating impurities and cannot achieve graded treatment of different types of impurities. If large particles, sludge, and light floating matter in wastewater cannot be effectively separated, it will affect the effectiveness and efficiency of subsequent treatment processes, making it difficult for the treated water quality to meet standards. Traditional sewage treatment equipment has low sludge removal efficiency and incomplete sludge separation. If the sludge in the sewage cannot be removed in a timely and effective manner, it will cause blockage of the internal pipes of subsequent treatment equipment, affecting the normal operation of the equipment and increasing maintenance costs and downtime. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a wastewater purification treatment device for water pollution control, comprising: The equipment includes a housing and a detachable top cover. The top cover seals the housing, preventing sewage from splashing out and external impurities from entering, while also facilitating access for internal component maintenance. Three semi-circular chambers (Sequentially, Semi-circular Chamber 1, Semi-circular Chamber 2, and Semi-circular Chamber 3) are sequentially fixedly installed at the bottom of the housing. These three semi-circular chambers process impurities in the sewage in a tiered manner. An inlet pipe is fixedly installed on the outer surface of the housing, with an inlet hopper fixedly installed at the inlet end. A hopper gate is rotatably installed on the top of the inlet hopper. The inlet pipe guides sewage from the inlet hopper into the equipment for treatment. The inlet hopper expands the inlet area, facilitating concentrated sewage entry. The hopper gate can close the inlet hopper to prevent external debris from falling in when not in use. An outlet pipe is fixedly installed in the middle of the bottom of Semi-circular Chamber 3. A valve is rotatably installed inside the outlet pipe. The outlet pipe discharges treated clean water from the equipment, and the valve controls the opening and closing of the outlet pipe. A support frame is fixedly installed on the outer surface of the housing. A water guiding mechanism is installed on the inner wall of the shell. The water guiding mechanism is used to guide sewage through the semi-circular chamber and separate large particulate impurities in the sewage by gravity. The sludge removal mechanism is installed at the bottom of the inner cavity of the shell and is located inside the semi-circular chamber 2. The sludge removal mechanism is used to separate sludge from sewage. A water-blocking mechanism is installed at the bottom of the inner cavity of the shell and is located between the semi-circular chamber two and the semi-circular chamber three. The water-blocking mechanism is used to prevent untreated sewage from directly entering the semi-circular chamber three, and at the same time cleans the sludge removal mechanism to prevent blockage. The sludge removal mechanism includes a motor, which is fixedly mounted on the outer surface of the housing via a bracket. A drive shaft is fixedly connected to the output end of the motor, and the drive shaft passes through the housing and extends into it. A separation cylinder is fixedly mounted at the end of the drive shaft, and the separation cylinder passes through the housing and extends to its outer side. The motor drives the drive shaft to rotate, and the drive shaft drives the separation cylinder to rotate. The separation cylinder separates the sludge in the sewage through centrifugal force. A cover plate is detachably mounted on the end of the separation cylinder away from the drive shaft. A handle is fixedly mounted on the outer surface of the cover plate, and a guide is fixedly mounted at the axial center of the cover plate. The outer surface of the separation cylinder has an inlet groove and an outlet hole. The inlet groove allows sewage flowing from the first semi-circular chamber to the second semi-circular chamber to enter the interior of the separation cylinder. The outlet hole is used to discharge the separated clean water from the separation cylinder and into the space between the second semi-circular chamber and the water-blocking mechanism.

[0004] Preferably, the bottom of the shell is inclined, and the semi-circular chamber one, semi-circular chamber two, and semi-circular chamber three are arranged in order from low to high. The water guiding mechanism is located directly above the semi-circular chamber one. The semi-circular chamber one is used to deposit large particulate impurities, the sludge removal mechanism in the semi-circular chamber two is used to separate sludge from sewage, and the semi-circular chamber three is used to separate light floating objects in the water. The light floating objects float on the water surface, and the water at the bottom is discharged through the water outlet pipe.

[0005] Preferably, the top of the housing has four corners with snap-fit ​​grooves, and the bottom of the top cover has four corners with snap-fit ​​strips. The snap-fit ​​strips are engaged with the snap-fit ​​grooves to achieve a stable connection between the top cover and the housing and easy disassembly.

[0006] Preferably, the guide includes a fixed rod, which is located at the center of the inner cavity of the separation cylinder. Arc-shaped plates are fixedly installed on both sides of the outer surface of the fixed rod. The arc-shaped plates guide the sewage to converge between their outer curved surface and the cylinder wall, so that the sludge adheres to the surface of the arc-shaped plates due to centrifugal force. The edge of the arc-shaped plates is sealed and adapted to the inner wall of the separation cylinder. When the sewage enters the second semi-circular chamber from the first semi-circular chamber, it enters the separation cylinder through the water inlet trough. When the separation cylinder rotates, the arc-shaped plates guide the sewage flow, causing it to converge between the outer curved surface of the arc-shaped plates and the inner wall of the separation cylinder. The sludge cannot pass through the water outlet and remains on the surface of the arc-shaped plates. The separated water is discharged through the water outlet.

[0007] Preferably, the water inlet tank and the water outlet are respectively arranged opposite to each other on both sides of the separator, the arc-shaped plate is arranged between the water inlet tank and the water outlet, and the water outlet is arranged on one side of the outer curved surface of the arc-shaped plate.

[0008] Preferably, a cross-shaped groove is provided at the center of the inner wall of the separation cylinder, and a cross-shaped locking block is fixedly installed at the end of the fixing rod away from the cover plate. The cross-shaped locking block is engaged and matched with the cross-shaped groove to ensure that the guide component rotates synchronously with the separation cylinder.

[0009] Preferably, the water guiding mechanism includes a first fixing plate, which is fixedly installed on the inner wall of the shell near the first semi-circular compartment. A rotating shaft is rotatably mounted on the outer surface of the first fixing plate via a bracket. An arc-shaped water guiding plate is fixedly installed on the outer surface of the rotating shaft. The arc-shaped water guiding plate uses its arc-shaped structure to guide sewage to the first semi-circular compartment and adapts to the impact of water flow by changing its own angle. An elastic band is fixedly installed on the side of the arc-shaped water guiding plate away from the shaft end. The elastic band uses its elasticity to buffer the impact of water flow on the arc-shaped water guiding plate and maintain the stable guidance of the arc-shaped water guiding plate. A fixing plate is fixedly installed on the other end of the elastic band. The fixing plate is fixedly installed at the bottom of the inner cavity of the shell and is located between the first semi-circular compartment and the second semi-circular compartment.

[0010] Preferably, the elastic bands are evenly distributed at the edge of the arc-shaped water guide plate, and the inner curved surface of the arc-shaped water guide plate is provided with a water guide groove. The water guide grooves and the elastic bands are staggered. The water guide grooves further guide the flow of sewage, avoid the dispersion of water flow, and ensure that the sewage enters the semi-circular chamber one in a concentrated manner.

[0011] Preferably, the water-blocking mechanism includes an arc-shaped baffle, which is fixedly installed at the bottom of the inner cavity of the shell. Fixing plates are fixedly installed on both sides of the arc-shaped baffle, and the fixing plates are fixedly installed on both sides of the inner wall of the shell. A water passage hole is opened at the bottom of the outer surface of the arc-shaped baffle, which is used to allow the clean water treated by the separation cylinder to flow from the semi-circular chamber two into the semi-circular chamber three. A brush strip is fixedly installed on the top of the inner curved surface of the arc-shaped baffle.

[0012] Preferably, the arc-shaped baffle is disposed between the second and third semi-circular chambers. The arc-shaped baffle is coaxially arranged with the separation cylinder. The arc-shaped baffle is used to block sewage that has not entered the separation cylinder, so that the sewage can be fully separated into sludge in the separation cylinder and then enter the third semi-circular chamber through the water outlet and water passage. The brush strip is pressed and adapted to the outer surface of the separation cylinder. The brush strip is used to clean the water outlet and prevent sludge blockage.

[0013] This invention provides a wastewater purification and treatment device for water pollution control. It has the following beneficial effects: I. This wastewater purification treatment equipment for water pollution control uses a semi-circular chamber setup. In the first semi-circular chamber, large particles of impurities are deposited by gravity. In the second semi-circular chamber, sludge is separated by a sludge removal mechanism. In the third semi-circular chamber, light floating matter floats to the top, and clean water is discharged from the bottom. The three chambers are arranged sequentially from low to high, utilizing gravity and density differences to achieve graded separation of impurities, avoiding the mixing of different types of impurities and affecting the purification effect, and ensuring that the impurity content of the final discharged water is significantly reduced.

[0014] II. This wastewater purification equipment for water pollution control, through the setting of a sludge removal mechanism, allows wastewater to enter the separation cylinder through the inlet tank. The arc-shaped plate of the guide component guides the wastewater to converge towards the cylinder wall. Centrifugal force causes the sludge to be trapped on the surface of the arc-shaped plate, while clean water is discharged through the outlet hole. The detachable cover plate can be removed by the handle for easy cleaning of the internal sludge. The sludge removal mechanism uses the centrifugal separation principle to efficiently separate sludge. The sealed guide design of the arc-shaped plate enhances the sludge trapping effect and prevents sludge from flowing out with the clean water. The detachable cover plate facilitates regular cleaning and ensures stable sludge removal efficiency, solving the problems of incomplete sludge separation and difficult cleaning in traditional equipment.

[0015] Third, the wastewater purification equipment for water pollution control uses a water-blocking mechanism. The arc-shaped baffle blocks wastewater that does not enter the separation cylinder, allowing it to complete sludge separation in the semi-circular chamber two. When the separation cylinder rotates, the brush strips squeeze and contact the cylinder wall, cleaning the residual sludge in the outlet hole in real time. The treated clean water enters the semi-circular chamber three through the water passage. The arc-shaped baffle ensures that the wastewater has undergone sufficient sludge removal treatment, preventing unpurified wastewater from flowing directly into the next stage. The brush strips can dynamically clean the outlet hole, preventing sludge blockage that would reduce the equipment's operating efficiency and improving the stability of continuous operation.

[0016] IV. The wastewater purification equipment for water pollution control, through the setting of the water guiding mechanism, the arc-shaped water guiding plate guides the water flow to the semi-circular chamber 1 through the water guiding channel. The rotating shaft, together with the elastic belt, buffers the water flow impact, ensuring that the wastewater flows into the chamber stably, avoiding the dispersion of water flow or excessive impact that causes large particles of impurities to float. The elastic belt can adapt to different water flow intensities, ensuring that large particles of impurities settle fully in the semi-circular chamber 1, and improving the separation efficiency of large particles of impurities.

[0017] V. This wastewater purification equipment for water pollution control features a top cover and a cover plate. The top cover is snapped into the housing via a locking strip, allowing for quick disassembly for internal maintenance. The cover plate is disassembled via a handle, facilitating the cleaning of sludge inside the separation cylinder and the maintenance of large particles deposited in the semi-circular chamber. This detachable design simplifies the equipment maintenance process, reduces maintenance difficulty and cost, prevents long-term accumulation of impurities from affecting equipment performance, and extends the equipment's service life.

An arc-shaped water guiding plate 73 is fixedly installed on the outer surface of the rotating shaft 72. The arc-shaped water guiding plate 73 uses its arc structure to guide the sewage flow to the semi-circular compartment 3, and adapts to the water flow impact by changing its own angle. An elastic band 75 is fixedly installed on the side of the arc-shaped water guiding plate 73 away from the shaft end.

A fixing piece 76 is fixedly installed on the other end of the elastic band 75. The fixing piece 76 is fixedly installed at the bottom of the inner cavity of the shell 1 and is located between the semi-circular compartment 3 and the semi-circular compartment 4. Elastic bands 75 are evenly distributed on the edge of the arc-shaped water guide plate 73. The inner curved surface of the arc-shaped water guide plate 73 is provided with a water guide groove 74. The water guide groove 74 and the elastic band 75 are staggered. The water guide groove 74 further guides the flow of sewage, avoids the dispersion of water flow, and ensures that the sewage enters the semi-circular chamber 3 in a concentrated manner. Water-blocking mechanism 9 is installed at the bottom of the inner cavity of the shell 1. The water-blocking mechanism 9 is located between the semi-circular chamber 2 4 and the semi-circular chamber 3 5. The water-blocking mechanism 9 is used to prevent untreated sewage from directly entering the semi-circular chamber 3 5, and at the same time cleans the sludge removal mechanism 8 to prevent blockage. The bottom of the shell 1 is set to be inclined. The semi-circular chamber 1 3, semi-circular chamber 2 4 and semi-circular chamber 3 5 are arranged in order from low to high. The water guiding mechanism 7 is located directly above the semi-circular chamber 1 3. The semi-circular chamber 1 3 is used to deposit large particles of impurities. The sludge removal mechanism 8 in the semi-circular chamber 2 4 is used to separate sludge in sewage. The semi-circular chamber 3 5 is used to separate light floating objects in the water. The light floating objects float on the water surface and the water at the bottom is discharged through the water outlet pipe 12.

[0022] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 9 As shown, the sludge removal mechanism 8 includes a motor 81, which is fixedly mounted on the outer surface of the housing 1 by a bracket. The output end of the motor 81 is fixedly connected to a drive shaft 82, which passes through the housing 1 and extends into it. A separation cylinder 83 is fixedly mounted at the end of the drive shaft 82, which passes through the housing 1 and extends to its outer side. The motor 81 drives the drive shaft 82 to rotate, and the drive shaft 82 drives the separation cylinder 83 to rotate. The separation cylinder 83 separates the sludge in the sewage by centrifugal force. A cover plate 85 is detachably mounted at the end of the separation cylinder 83 away from the drive shaft 82. A handle 89 is fixedly mounted on the outer surface of the cover plate 85, and a guide 86 is fixedly mounted at the axis of the cover plate 85. A water inlet trough 87 and a water outlet 88 are provided on the outer surface of the separation cylinder 83. The water inlet trough 87 allows the sewage flowing from the semi-circular chamber 1 to the semi-circular chamber 2 to enter the separation cylinder 83. The water outlet 88 is used to discharge the separated clean water from the separation cylinder 83 and into the space between the semi-circular chamber 2 and the water blocking mechanism 9. The guide member 86 includes a fixed rod 861, which is located at the center of the inner cavity of the separation cylinder 83. Arc-shaped plates 862 are fixedly installed on both sides of the outer surface of the fixed rod 861. The arc-shaped plates 862 guide the sewage to converge between its outer curved surface and the cylinder wall, so that the sludge adheres to the surface of the arc-shaped plates 862 due to centrifugal force. The edge of the arc-shaped plates 862 is sealed and adapted to the inner wall of the separation cylinder 83. When the sewage enters the semi-circular chamber 4 from the semi-circular chamber 1 3, it enters the separation cylinder 83 through the water inlet trough 87. When the separation cylinder 83 rotates, the arc-shaped plates 862 guide the sewage flow, so that it converges between the outer curved surface of the arc-shaped plates 862 and the inner wall of the separation cylinder 83. The sludge cannot pass through the water outlet 88 and remains on the surface of the arc-shaped plates 862. The separated water is discharged through the water outlet 88. The water inlet trough 87 and the water outlet 88 are respectively arranged on both sides of the separator 83. The arc plate 862 is arranged between the water inlet trough 87 and the water outlet 88, and the water outlet 88 is arranged on one side of the outer curved surface of the arc plate 862. A cross-shaped groove 84 is provided at the center of the inner wall of the separator 83. A cross-shaped block 863 is fixedly installed at the end of the fixing rod 861 away from the cover plate 85. The cross-shaped block 863 and the cross-shaped groove 84 are engaged and matched to ensure that the guide 86 rotates synchronously with the separator 83.

[0023] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 10 As shown, the water-blocking mechanism 9 includes an arc-shaped baffle 91, which is fixedly installed at the bottom of the inner cavity of the housing 1. Fixing plates 92 are fixedly installed on both sides of the arc-shaped baffle 91, and the fixing plates 92 are fixedly installed on both sides of the inner wall of the housing 1. A water passage hole 93 is opened at the bottom of the outer surface of the arc-shaped baffle 91. The water passage hole 93 is used to allow the clean water treated by the separation cylinder 83 to flow from the semi-circular chamber 4 into the semi-circular chamber 5. A brush strip 94 is fixedly installed on the top of the inner curved surface of the arc-shaped baffle 91. An arc-shaped baffle 91 is installed between the semi-circular chamber 2 4 and the semi-circular chamber 3 5. The arc-shaped baffle 91 is coaxially arranged with the separation cylinder 83. The arc-shaped baffle 91 is used to block the sewage that has not entered the separation cylinder 83, so that the sewage can be fully separated into sludge in the separation cylinder 83, and then enter the semi-circular chamber 3 5 through the water outlet hole 88 and the water passage hole 93. The brush strip 94 is pressed and fitted with the outer surface of the separation cylinder 83. The brush strip 94 is used to clean the water outlet hole 88 and prevent sludge blockage.

[0024] When in use, the operator opens the hopper door 11 at the top of the inlet hopper 10. After the sewage is collected through the inlet hopper 10, it flows into the interior of the shell 1 through the inlet pipe 6, completing the initial introduction. After the sewage enters the shell 1, it first contacts the water guiding mechanism 7. The rotating shaft 72 supported by the fixed plate 71 drives the arc-shaped water guiding plate 73 to rotate. The water guiding groove 74 on the inner curved surface of the arc-shaped water guiding plate 73 guides the sewage to flow to the semi-circular chamber 3 at the lowest position at the bottom of the shell 1. The elastic band 75 buffers the impact of the water flow to ensure stable sewage inflow. Wastewater settles naturally in semi-circular chamber 3 due to gravity. Large particles settle at the bottom of the chamber due to their weight. The pre-purified wastewater continues to flow and enters semi-circular chamber 4. It flows into the interior of separation cylinder 83 through the water inlet trough 87 on the outer surface of the separation cylinder 83. The motor 81 starts and drives the separation cylinder 83 to rotate through the drive shaft 82. The guide component 86 inside the separation cylinder 83 rotates synchronously with it. At this time, the cross-shaped locking block 863 is locked and fixed with the cross-shaped locking groove 84. The arc plates 862 on both sides of the fixing rod 861 guide the wastewater to gather between the outer curved surface of the arc plate 862 and the inner wall of the separation cylinder 83. The sludge is separated by centrifugal force. The sludge particles are too large to pass through the water outlet 88 and are intercepted and attached to the surface of the arc plate 862. The separated clean water is discharged from the separation cylinder 83 through the water outlet 88 and enters the interior of semi-circular chamber 4. The arc-shaped baffle 91 of the water-blocking mechanism 9 blocks the sewage that has not entered the separation cylinder 83, so that it can complete the sludge separation in the semi-circular chamber 2 4 and avoid direct flow into the semi-circular chamber 3 5. When the separation cylinder 83 rotates, the brush strip 94 on the inner curved surface of the arc-shaped baffle 91 squeezes and contacts the outer surface of the separation cylinder 83, cleaning the residual sludge on the surface of the water outlet 88 in real time to prevent blockage. The treated water flows into the semi-circular compartment 3 5 at the highest point of the bottom of the shell 1 through the water passage 93 at the bottom of the arc-shaped baffle 91. Light floating matter in the sewage, such as grease and foam, floats on the water surface due to its low density, while the clean water settles at the bottom of the compartment. The valve 16 inside the outlet pipe 12 is opened, and the clean water at the bottom of the semi-circular compartment 3 5 is discharged through the outlet pipe 12, completing the purification process. During regular maintenance, the top cover 2 can be separated from the top of the housing 1 by the locking strip 15 at the bottom of the top cover 2 and the locking groove 14 at the top of the housing 1. The top cover 2 can be removed, and the cover plate 85 can be removed by holding the handle 89. The sludge on the surface of the arc plate 862 inside the separation cylinder 83 can be cleaned, and large particles of impurities at the bottom of the semi-circular chamber 3 can also be cleaned.
