Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically referring to a multi-stage purification device for water treatment. Background Technology

[0002] Existing wastewater treatment equipment has significant shortcomings in impurity treatment. It is difficult to simultaneously and efficiently collect floating impurities on the water surface and sediment at the bottom. Most equipment simply sets up a sludge-blocking structure at the inlet or outlet, which can only treat one type of impurity. It also relies on filter screens to filter impurities, but the filter screens need to be manually disassembled and cleaned regularly, which makes it easy for impurities to remain and affect the quality of the effluent. Furthermore, it cannot classify and treat impurities, which makes the filter screens easy to clog. It is difficult to balance treatment efficiency, structural simplification and economy, and it cannot meet the usage requirements of efficient, low-consumption and easy-to-maintain water collection equipment. Summary of the Invention

[0003] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a multi-stage purification device for water treatment, which effectively solves the above problems.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a multi-stage purification device for water treatment, including a water collection cylinder, a float ring and a driver, wherein the float ring is slidably disposed in the water collection cylinder and the driver is disposed at the bottom of the water collection cylinder.

[0005] Furthermore, the water collecting cylinder includes a cylinder body, a bottom plate, and a drain pipe. The bottom plate is located at the bottom of the cylinder body, and the drain pipe is located at the bottom of the bottom plate. The bottom plate is funnel-shaped. The inner wall of the cylinder body has a circumferential array of grooves, and the bottom of each groove has a slot. The width of the slot is the same as that of the groove. The side wall of the cylinder body has a drain outlet. The inner wall of the cylinder body has a connecting pipe that communicates with the drain outlet. The drain pipe has a valve located at the bottom. The valve is located above the valve, and the actuator is located at the top of the support. The top of the cylinder body has a top cover, and the bottom of the bottom plate has supporting feet.

[0006] The connecting pipe is a flexible hose that can be bent arbitrarily according to the change of the floating ring position, and the drain outlet is connected to an external drain pump.

[0007] Furthermore, the floating ring is made of low-density material and includes a main ring, which includes a ring body and a water collection tank. The top of the ring body is provided with an electric telescopic rod, and the side wall of the water collection tank is provided with a baffle. A connecting rod is provided between the baffle and the electric telescopic rod. A guide plate is provided at the bottom of the baffle near the axis of the ring body. The guide plate is inclined. A slider is arranged in a circular array on the outer wall of the main ring. The slider is slidably disposed in a groove. An insert plate is provided at the bottom of the slider and is inserted into a slot. A float is provided on the bottom wall of the water collection tank. The bottom wall of the float is inclined. An interface is provided on the top wall of the ring body and is connected to a connecting pipe.

[0008] The ring body and the float are the main components that provide buoyancy for the floating ring. Therefore, they are made of materials with lower density than other components of the floating ring. The bottom wall of the float is inclined so that impurities floating in the water can gather to the top of the water surface during the static process. When the water flows and rotates in the cylinder, the electric telescopic rod lifts the baffle upward. The inclined guide plate can facilitate the entry of impurities floating on the water surface into the water collection chamber.

[0009] The floating ring can float on the water surface according to the water volume in the collection cylinder. As the floating ring moves, the insert plate can block the groove located below the slider, maintain the integrity of the inner wall of the cylinder, and prevent the unevenness of the inner wall from affecting the water flow direction.

[0010] Furthermore, the driver includes an electric telescopic rod, an extension rod, and a blade. The extension rod is located at the top of the electric telescopic rod, and the blade is located at the top of the extension rod. The blade rotates electrically. A sealing plug is provided between the electric telescopic rod and the extension rod. The sealing plug separates the cylinder from the drain pipe, and the top wall of the sealing plug is inclined.

[0011] The beneficial effects of this invention using the above structure are as follows: This solution provides a multi-stage purification device for water treatment. After water is collected in the collection cylinder and allowed to settle, impurities are divided into two categories: high-density impurities that settle at the bottom and low-density impurities that float on the surface. Controlling the extension of the first electric telescopic rod moves the sealing plug upward, connecting the cylinder to the drain pipe. Controlling the extension of the second electric telescopic rod raises the baffle, opening the collection chamber, and controlling the blades to rotate, causing the water inside the cylinder to rotate. As the blades move, the impurities floating on the surface are thrown into the collection chamber by centrifugal force and collected, then discharged outside the cylinder by an external water pump. The funnel-shaped design of the bottom plate allows the deposited impurities to naturally gather towards the center. However, some impurities will still adhere to the bottom plate. When the water rotates inside the cylinder, the deposited and attached impurities will be attracted to the center by the centripetal force and become more concentrated. After the impurities at the bottom of the water are concentrated, the blades are controlled to stop rotating, and the water inside the cylinder gradually becomes still. The impurities that have gathered and rotated at the center of the bottom of the water will also slowly become still and fall into the drain pipe for collection. At this time, the electric telescopic rod retracts, the sealing plug re-seals the drain pipe, and then the valve is opened to discharge the denser impurities. This method only requires a small amount of water stored in the cylinder to classify and discharge the impurities. Compared with the traditional filter screen filtration method, there is no need for manual maintenance and replacement of the filter screen. Moreover, this "collect water first, then filter" method can make full use of idle time and is more efficient. Attached Figure Description

[0017] like Figures 1-8 As shown, the present invention provides a multi-stage purification device for water treatment, including a water collection cylinder 1, a float ring 3 and a driver 2. The float ring 3 is slidably disposed inside the water collection cylinder 1, and the driver 2 is disposed at the bottom of the water collection cylinder 1.

[0018] Furthermore, the water collecting cylinder 1 includes a cylinder body 101, a bottom plate 103, and a drain pipe 105. The bottom plate 103 is located at the bottom of the cylinder body 101, and the drain pipe 105 is located at the bottom of the bottom plate 103. The bottom plate 103 is funnel-shaped. The inner wall of the cylinder body 101 has a circumferential array of grooves 106, and the bottom of the grooves 106 has a slot 107. The width of the slot 107 is the same as that of the grooves 106. The side wall of the cylinder body 101 has a drain outlet 108. The inner wall of 101 is provided with a connecting pipe 111, which is connected to the drain outlet 108. A valve 110 is provided inside the drain pipe 105, which is located at the bottom of the drain pipe 105. A bracket 109 is located above the valve 110, and the driver 2 is located at the top of the bracket 109. A top cover 102 is provided on the top of the cylinder 101, and a support foot 104 is provided at the bottom of the bottom plate 103. The connecting pipe 111 is a flexible hose, and an external drain pump is connected to the drain outlet 108.

[0019] Furthermore, the floating ring 3 is made of low-density material. The floating ring 3 includes a main ring 31, which includes a ring body 311 and a water collection tank 312. The top of the ring body 311 is provided with an electric telescopic rod 316, and the side wall of the water collection tank 312 is provided with a baffle 314. A connecting rod 317 is provided between the baffle 314 and the electric telescopic rod 316. The bottom of the baffle 314 near the axis of the ring body 311 is provided with a guide plate 315, which is inclined. The outer wall of the main ring 31 is provided with a circumferential array of sliders 32, which slide in the groove 106. The bottom of the slider 32 is provided with an insert plate 33, which is inserted into the slot 107. The bottom wall of the water collection tank 312 is provided with a float 313, which is inclined. The top wall of the ring body 311 is provided with an interface 318, which is connected to the connecting pipe 111. The ring body 311 and the float 313 are made of a material with a lower density than other parts of the floating ring 3.

[0020] Furthermore, the driver 2 includes an electric telescopic rod 201, an extension rod 203, and a blade 204. The extension rod 203 is located at the top of the electric telescopic rod 201, and the blade 204 is located at the top of the extension rod 203. The blade 204 rotates electrically. A sealing plug 202 is provided between the electric telescopic rod 201 and the extension rod 203. The sealing plug 202 separates the cylinder 101 from the drain pipe 105. The top wall of the sealing plug 202 is inclined.

[0021] In practical use, after the water in the cylinder has settled, the impurities in the water are mainly divided into two categories: high-density impurities that settle at the bottom and low-density impurities that float on the surface. The electric telescopic rod 201 is extended, the sealing plug 202 moves upward, and the cylinder 101 connects to the drain pipe 105. Simultaneously, the electric telescopic rod 316 is extended, raising the baffle 314, opening the water collection chamber 312, and the blades 204 are rotated, causing the water in the cylinder to gradually begin to rotate (the water flow should be stable and continuous; violent rotation should not cause the impurities to be disturbed again). As the blades 204 move, the impurities floating on the surface are thrown into the water collection chamber 312 by centrifugal force. The funnel-shaped design of the bottom plate 103 allows the deposited impurities to gather towards the natural center, but some still remain. Impurities adhere to the bottom plate 103. When the water rotates inside the cylinder, the deposited and attached impurities are concentrated towards the center due to centripetal force. After the impurities at the bottom of the water are concentrated, the control blade 204 stops rotating, and the water inside the cylinder gradually becomes still. The impurities that have gathered and rotated at the center of the bottom of the water will also slowly become still and fall into the drain pipe 105 for collection. At this time, the electric telescopic rod 201 retracts, and the sealing plug 202 re-seals the drain pipe 105. Then, the valve 110 is opened to discharge the impurities with higher density. At the same time, the control electric telescopic rod 201 retracts, and the baffle 314 re-seals the water collection chamber 312 to prevent impurities from leaving the water collection chamber 312. After the water surface and impurities are stable, the external water pump is started to continuously pump out the surface water through the interface 318 and discharge the floating impurities outside the cylinder.
