Description

Technical Field

[0001] This invention relates to the field of surface water filtration technology, specifically to a harbor-type pump pool structure and operation method based on surface water utilization. Background Technology

[0002] Surface water refers to all dynamic and static water on the land surface, also known as "terrestrial water." It includes various liquid and solid water bodies, mainly rivers, lakes, swamps, glaciers, and ice sheets. It is one of the important sources of water for human life and a major component of water resources in various countries.

[0003] The "Surface Water Filtration and Purification Device and its Purification Process" disclosed in application number "CN117285196B" is also an increasingly mature technology. It "includes a first housing and a second housing connected to the side of the first housing. A primary filter assembly is connected inside the first housing, and the output end of the primary filter assembly is connected to a waste collection device via a connecting assembly.

[0004] However, the above-mentioned surface water filtration and purification device design has the following drawbacks: the surface water filtration and purification device can only remove larger solid particles in the surface water through the primary filter component, and cannot remove impurities in the surface water through multiple processes. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a harbor-type pumping station structure and operation method for surface water utilization, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a harbor-type pump pool structure based on surface water utilization, comprising a channel, wherein a steel mesh inclined filter screen groove is provided on the inner wall of one side of the channel, a pool front filtration mechanism is provided inside the steel mesh inclined filter screen groove, a filter screen groove is provided on one side of the steel mesh inclined filter screen groove, a filter cylinder is connected through the outlet end of the filter screen groove, the interior of the filter cylinder is divided into a left chamber and a right chamber by a steel plate partition wall, a conveying mechanism is provided inside the right chamber, a sand and gravel filtration mechanism is connected through the outlet end of the conveying mechanism, and a disc filter mechanism is provided on one side of the sand and gravel filtration mechanism.

[0007] Preferably, the pool front filtration mechanism includes an inlet gate groove inside the filter screen groove, pool front filter screen grooves on both sides of the inlet gate groove, an inlet gate valve inserted inside the inlet gate groove, a first layer of filter screen and a second layer of filter screen respectively inserted and connected inside the two pool front filter screen grooves, and the apertures of the first layer of filter screen and the second layer of filter screen are 23.4mm and 11.2mm respectively, and an inclined filter screen is installed on one side of the filter screen groove.

[0008] Preferably, the conveying mechanism includes a water pump bracket disposed inside the right chamber, a submersible pump fixedly connected to the top of the water pump bracket, a water delivery pipe fixedly connected to the top of the submersible pump, and fixed clamps fixedly connected to the top and bottom sides of the submersible pump.

[0009] Preferably, the sand and gravel filtration mechanism includes two sand and gravel filters that are connected to the top of one end of the water supply pipe, and a water inlet pipe is connected to one side of each sand and gravel filter.

[0010] Preferably, the disc filter mechanism includes a solenoid valve controller fixedly connected to one side of the inlet pipe, a fixed pull rod fixedly connected to the bottom end of the solenoid valve controller, an outlet pipe fixedly connected to the bottom end of the fixed pull rod, four grooved pipe joints passing through the bottom end of the inlet pipe, three-way drain valves passing through the bottom end of the grooved pipe joints, a drain pipe passing through one side of several three-way drain valves, a double-headed disc filter head installed at the bottom end of the three-way drain valve, an outlet pipe fixedly connected to the bottom end of the double-headed disc filter head, a plug installed in the middle of the outlet pipe, an air vent valve installed at the top of the inlet pipe, and a disc Y-type filter provided on one side of the top of the inlet pipe.

[0011] Preferably, the steel plate partition wall includes several sets of angle steel, each set of angle steel has a stainless steel filter screen installed inside, several steel bars are installed on both sides of the angle steel from top to bottom, and a steel bar handle is fixedly connected to the top of the angle steel. The stainless steel filter screen 1032 has a φ1.5mm diameter and an aperture of 11.2mm, and the steel bar 1033 has a Φ8mm diameter.

[0012] A method for operating a harbor-type pumping station based on surface water utilization includes the following steps: Step 1, Surface water introduction and primary filtration: Surface water flows in through a channel and undergoes preliminary filtration through a steel mesh inclined filter screen groove on the inner wall of the channel to intercept large particles and floating debris. The inclined filter screen utilizes gravity to enhance the solid-liquid separation effect. Subsequently, the water flows into the filter screen groove and then into the pre-pool filtration mechanism. By manually adjusting the inlet gate, the water flows sequentially through the first layer of filter screen (pore size 23.4 mm) and the second layer of filter screen (205) (pore size 11.2 mm) to further remove medium-sized particles.

[0013] Step Two: Chamber Separation and Transport: The filtered water enters the filter cylinder and is separated into a left and right chamber by a steel plate partition wall. The steel plate partition wall contains a stainless steel filter screen (11.2mm aperture, 8mm steel reinforcement) to further adsorb suspended solids. In the right chamber, a submersible pump transports water through a pipeline to the sand and gravel filtration mechanism. The sand and gravel filtration mechanism removes heavy particulate impurities such as sand and gravel mixed in the water. The filtered water then enters the disc filter mechanism through the inlet pipe.

[0014] Step 3: Stacked fine filtration and backup switching The disc filter mechanism employs four sets of parallel Y-type disc filters, using double-headed disc filter heads to remove fine impurities. During normal operation, two sets are in use, with the other two on standby. If a running set becomes clogged or damaged, a solenoid valve controller switches to the standby set to ensure continuous filtration. Filtered water is discharged through an outlet pipe, while impurities are periodically removed via a three-way drain valve and drain pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a harbor-type pumping station structure and operation method based on surface water utilization: 1. Surface water contains impurities and requires various filtration and impurity removal processes before irrigation. The surface water flows through channels and into the inclined steel mesh filter trough, where it is filtered to remove large fixed particles and floating matter. The water then flows through the filter trough and undergoes further filtration by the pre-pool filtration mechanism. After filtration, the surface water passes through a sand and gravel filtration mechanism to remove sand and gravel mixed in with the surface water. Finally, it passes through a disc filter mechanism to thoroughly remove impurities. The surface water passes through the first and second layers of filters inside the two pre-pool filter troughs to remove impurities mixed in with the surface water, and the sand and gravel filter removes sand and gravel from the surface water.

[0016] 2. Water can be filtered through the Y-type disc filters on the four sets of disc filter mechanisms. During the filtration process, two sets of disc filter mechanisms are used. The solenoid valve controller controls the opening of two sets of three-way drain valves to filter the surface water. The double-headed disc filter head filters out fine impurities in the water, and then the water is discharged and collected through the outlet pipe. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example 1: As Figures 1-10As shown, the present invention proposes a harbor-type pump pool structure based on surface water utilization, including a channel 1. A steel mesh inclined filter screen groove 101 is provided on the inner wall of one side of the channel 1. A front-pool filtration mechanism 2 is provided inside the steel mesh inclined filter screen groove 101. A filter screen groove 106 is provided on one side of the steel mesh inclined filter screen groove 101. A filter cylinder 102 is connected through the water outlet end of the filter screen groove 106. The interior of the filter cylinder 102 is divided into a left chamber 104 and a right chamber 105 by a steel plate partition wall 103. A conveying mechanism 3 is provided inside the right chamber 105. A sand and gravel filtration mechanism 4 is connected through the water outlet end of the conveying mechanism 3. A stacked plate filtration mechanism 5 is provided on one side of the sand and gravel filtration mechanism 4.

[0024] In practical use, surface water contains impurities and needs to be filtered and removed before irrigation. The surface water flows through channel 1 and into the inclined steel mesh filter trough 101. It then passes through the inclined filter 206 to filter out large fixed particles and floating matter. The water then flows through the filter trough 106 and passes through the pre-pool filtration mechanism 2 for further filtration. After filtration, the sand and gravel mixed in with the surface water are removed by the sand and gravel filtration mechanism 4. Finally, the impurities are thoroughly filtered out by the disc filter mechanism 5.

[0025] The pool front filtration mechanism 2 includes an inlet gate groove 201 disposed inside the filter screen groove 106, and pool front filter screen grooves 202 disposed on both sides of the inlet gate groove 201. An inlet gate 203 is inserted inside the inlet gate groove 201. A first layer filter screen 204 and a second layer filter screen 205 are respectively inserted and connected inside the two pool front filter screen grooves 202. The apertures of the first layer filter screen 204 and the second layer filter screen 205 are 23.4mm and 11.2mm respectively. An inclined filter screen 206 is installed on one side of the filter screen groove 106.

[0026] In practical use, during filtration, the inlet gate 203 inside the inlet gate trough 201 is opened manually, and the surface water passes through the first layer filter screen 204 and the second layer filter screen 205 inside the two pool front filter screen troughs to remove impurities mixed inside the surface water.

[0027] The conveying mechanism 3 includes a water pump bracket 301 disposed inside the right chamber 105, a submersible pump 302 fixedly connected to the top of the water pump bracket 301, a water delivery pipe 303 fixedly connected to the top of the submersible pump 302, and fixed clamping plates 304 fixedly connected to the top and bottom sides of the submersible pump 302.

[0028] In practical use, the submersible pump 302 is fixed by the water pump bracket 301, and the water filtered in the pool is transported to the sand and gravel filtration mechanism 4 through the water supply pipe 303. The submersible pump 302 is fixed inside the filter cylinder 102 by the fixed clamp 304.

[0029] The sand and gravel filtration mechanism 4 includes two sand and gravel filters 401 that are connected to the top of one end of the water supply pipe 303, and a water inlet pipe 402 is connected to one side of the sand and gravel filters 401.

[0030] In practical use, the sand and gravel inside the surface water are filtered through the sand and gravel filter 401, and the surface water after filtration is transported to the disc filter mechanism 5 through the water inlet pipe 402.

[0031] The disc filter mechanism 5 includes a solenoid valve controller 501 fixedly connected to one side of the inlet pipe 402. A fixed pull rod 502 is fixedly connected to the bottom end of the solenoid valve controller 501. An outlet pipe 503 is fixedly connected to the bottom end of the fixed pull rod 502. Four grooved pipe joints 504 are connected through the bottom end of the inlet pipe 503. A three-way drain valve 505 is connected through the bottom end of each grooved pipe joint 504. A drain pipe 506 is connected through one side of each three-way drain valve 505. A double-headed disc filter head 507 is installed at the bottom end of the three-way drain valve 505. An outlet pipe 503 is fixedly connected to the bottom end of the double-headed disc filter head 507. A plug 509 is installed in the middle of the outlet pipe 503. An air vent valve 508 is installed at the top of the inlet pipe 402. A disc Y-type filter 5010 is provided on one side of the top of the inlet pipe 402.

[0032] In practical use, water can be filtered through the stacked Y-type filters 5010 on the four sets of stacked filter mechanisms 5. During the filtration process, two sets of stacked filter mechanisms 5 are used, while the other two are kept as backups. If a malfunction occurs during normal filtration, the other two backup stacked filter mechanisms 5 can be activated in time to perform filtration. Water enters through the inlet pipe 402, and then the solenoid valve controller 501 controls the opening of two sets of three-way drain valves 505 to filter and transport surface water. Fine impurities in the water are filtered out through the double-headed stacked filter head 507, and then discharged and collected through the outlet pipe 503.

[0033] The steel plate partition wall 103 includes several sets of angle steel 1031. Each set of angle steel 1031 has a stainless steel filter screen 1032 installed inside. Several steel bars 1033 are installed on both sides of the angle steel 1031 from top to bottom. A steel bar handle 1034 is fixedly connected to the top of the angle steel 1031. The stainless steel filter screen 1032 has a diameter of 1.5mm and a hole diameter of 11.2mm. The steel bars 1033 have a diameter of 8mm.

[0034] In practical use, the angle steel 1031 installed on the steel plate partition wall 103 facilitates the fixed installation of the stainless steel filter screen 1032 for use during filtration. The steel bar handle 1034 facilitates the lifting and use of the stainless steel filter screen 1032 for cleaning and replacement.

[0035] A method for operating a bay-type pumping station based on surface water utilization includes the following steps: Step 1: Surface Water Introduction and Primary Filtration: Surface water flows in through channel 1 and undergoes initial filtration through the inclined steel mesh filter trough 101 on the inner wall of the channel, intercepting large particles and floating debris. The inclined filter 206 utilizes gravity to enhance solid-liquid separation. The water then flows into the filter trough 106 and enters the pre-pool filtration mechanism 2. By manually adjusting the inlet gate 203, the water flows sequentially through the first filter 204 (23.4mm aperture) and the second filter 205 (11.2mm aperture), further removing medium-sized particles.

[0036] Step 2, Chamber Separation and Transport: The filtered water enters the filter cylinder 102, which is divided into a left chamber 104 and a right chamber 105 by a steel plate partition wall 103. The steel plate partition wall 103 contains a stainless steel filter screen 1032 with an 11.2mm aperture and 8mm reinforcing steel bars to further adsorb suspended solids. In the right chamber 105, a submersible pump 302 transports water through a water supply pipe 303 to the sand and gravel filtration mechanism 4. The sand and gravel filtration mechanism 4 removes heavy particulate impurities such as sand and gravel mixed in the water through a sand and gravel filter 401. The filtered water then enters the disc filter mechanism 5 through the inlet pipe 402.

[0037] Step 3: Stacked fine filtration and backup switching The disc filter mechanism 5 employs four sets of parallel disc Y-type filters 5010, which remove fine impurities through double-headed disc filter heads 507. During normal operation, two sets are in use, with the other two on standby. If a set becomes clogged or damaged, the solenoid valve controller 501 switches to the standby set to ensure continuous filtration. The filtered water is discharged through the outlet pipe 503, and impurities are periodically removed through the three-way drain valve 505 and the drain pipe 506.

[0038] Example 2: One side of the filter screen groove 106 is connected to the filter cylinder 102 through a steel pipe 6. Additional notes: The top of the filter cylinder 102 is flush with the top of the channel. A 20cm thick concrete pad 7 is cast in place at the top of the filter cylinder 102. A 50cm gravel pad 8 is set at the bottom of the concrete pad 7. The two sides of the filter cylinder 102 are filled with earthwork.

[0039] When filtering and removing impurities from surface water, a relatively long steel pipe 6 is installed with the filter cylinder 102 to perform filtration. The filter cylinder 102 is supported and fixed by a concrete cushion layer 7 and a gravel cushion layer 8.
