Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a river water treatment device. Background Technology

[0002] With the acceleration of urbanization and the intensification of human activities, a large amount of pollutants are discharged into natural water bodies, leading to problems such as eutrophication, increased suspended solids, and floating garbage in many rivers, severely damaging the aquatic ecological environment. In order to improve water quality and restore river functions, physical, chemical, or biological methods are usually required for treatment. Among them, physical filtration is widely used because of its rapid effectiveness and intuitive operation. Currently, common river water treatment equipment typically uses a water pump to directly draw the river water to be treated into the equipment, and uses built-in filters, filter elements or filter media to intercept and filter suspended solids, algae and some solid waste in the water. However, this direct suction treatment method has significant drawbacks in actual operation. Specifically, the river water has a complex composition, containing a large number of floating objects and garbage of varying sizes and shapes, such as leaves, plastic bags, fibers, and long strips of aquatic plants. These debris are very easy to get tangled and cover the inlet or filter holes of the filter unit during the suction process, which quickly causes physical blockage and significantly reduces filtration efficiency and water treatment throughput. Summary of the Invention

[0003] The purpose of this invention is to provide a river water treatment device.

[0004] The objective of this invention is achieved through the following technical solution: a river water treatment device, comprising a box, a sealed top plate installed on the box, and a filter element body disposed inside the box; The inner cavity of the box is equipped with a squeezing mechanism for pre-treating the river water before it enters the filter body. The extrusion mechanism includes a bracket fixed inside the housing and a drive seat mounted on the bracket and capable of reciprocating along a first direction. A rotating shaft is rotatably connected to the drive seat, and a pressure block is fixedly connected to one end of the rotating shaft. The surface of the pressure block is provided with multiple drainage holes. The bottom of the sealing top plate is fixedly provided with an extrusion tube whose position corresponds to the pressure block, and a discharge pipe is provided on one side of the box body, and the extrusion tube is connected to the discharge pipe; A motion conversion unit is provided between the drive seat and the rotating shaft, which is used to drive the rotating shaft and the pressure block to rotate when the drive seat reciprocates. A sealed discharge assembly controlled by the movement of the drive seat is provided at the discharge pipe.

[0005] The motion conversion unit includes a diagonal rod fixedly installed on the inner wall of the housing, a connecting block slidably sleeved on the diagonal rod, a rack rotatably connected to the connecting block and slidably engaged with the drive seat, and a gear fixedly sleeved on the rotating shaft, wherein the gear meshes with the rack.

[0006] The reciprocating motion of the drive seat is driven by the drive assembly; The drive assembly includes a drive component fixedly mounted on the sealing top plate, a cam driven by the output shaft of the drive component, and a slider rotatably connected to the cam. A T-shaped transmission plate is fixedly connected to the drive base, and the slider is slidably disposed in the groove of the T-shaped transmission plate.

[0007] A filter box is slidably connected inside the housing, and the filter element body is disposed inside the filter box. A filter plate is detachably installed on the top of the filter box. Multiple elastic elements b are fixedly connected inside the housing. A pressure plate is fixedly connected to one end of each elastic element b. The bottom of the pressure plate is in contact with the surface of the filter plate. The drive base is also connected to a self-cleaning unit that works in conjunction with the filter box, which is used to drive the filter box and filter element body to vibrate when the drive base reciprocates.

[0008] The self-cleaning unit includes a corrugated plate symmetrically fixed to the bottom of the filter box and a mating rod fixed to the drive seat. A ball bearing is rotatably connected to the end of the mating rod, and the ball bearing contacts the corrugated surface of the corrugated plate.

[0009] The sealing and discharging assembly includes a T-shaped sealing plate slidably disposed on one side of the box via a guide rod, an elastic element a for applying an elastic sealing force to the T-shaped sealing plate, and a pressure rod fixedly connected at one end to the T-shaped sealing plate. The drive seat is connected to a pushing component, which is used to push the pressure rod during the stroke of the pressure block performing the discharge action, so that the T-shaped sealing plate overcomes the elastic force of the elastic element a and opens the discharge pipe.

[0010] The pushing component includes an L-shaped push rod fixed to the bottom of the drive seat. A limiting groove is provided at the bottom of the bracket. The L-shaped push rod is slidably disposed in the limiting groove and can contact and push the pressure rod when the drive seat moves to a specific position.

[0011] The top of the sealed top plate is provided with a water inlet pipe, which is connected to the extrusion pipe, and the other side of the box is provided with a drain pipe.

[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. To address the problem of loose floating matter directly clogging filter pores in existing technologies, this invention incorporates a pretreatment station consisting of a squeezing tube and a pressing block before filtration. The pressing block is driven by a drive unit to reciprocate and rotate within the squeezing tube, forcibly dehydrating and compressing loose impurities such as leaves and fibers trapped in the water into dense blocks. This process transforms easily tangled and fluffy impurities into tightly structured solids, reducing the risk of them entering and clogging downstream filter cartridges, thus ensuring the smooth flow of the filtration process from the source.

[0013] 2. To address the drawback of frequent shutdowns for cleaning after blockage, this invention achieves automatic discharge of impurities. This is also controlled by the movement of the drive unit. The L-shaped push rod at its bottom pushes the pressure rod of the sealing discharge assembly during a specific stroke, automatically opening the discharge port and allowing the compacted impurity blocks to be smoothly ejected from the equipment. Subsequently, the sealing assembly automatically resets under the action of the elastic element. This process allows impurity cleaning without interrupting the main filtration process, achieving long-term continuous and stable operation of the equipment and reducing maintenance frequency and labor costs.

[0014] 3. To address the problem of passive clogging of existing equipment filter units, this invention designs the filter unit (filter box and filter element) as a vibrating self-cleaning structure. The reciprocating motion of the drive seat, through the cooperating rod and ball bearings, acts on the wave plate at the bottom of the filter box, converting linear motion into continuous up-and-down vibration of the filter box. This vibration is effectively transmitted to the internal filter element, continuously shaking off fine particles attached to the surface and pores of the filter element, significantly delaying the degradation of the filter element's own performance, and maintaining stable filtration throughput and effect.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figure 1-8 The diagram shown is a schematic representation of an embodiment of a river water treatment device provided by the present invention, including a housing 1, a sealed top plate 101 installed on the housing 1, and a filter element body 102 disposed inside the housing 1. The inner cavity of the housing 1 is equipped with a squeezing mechanism for pre-treating the river water before it enters the filter body 102. The extrusion mechanism includes a bracket 2 fixed inside the housing 1 and a drive seat 201 disposed on the bracket 2 and capable of reciprocating along a first direction. A rotating shaft 202 is rotatably connected to the drive seat 201, and a pressure block 203 is fixedly connected to one end of the rotating shaft 202. A plurality of drainage holes 204 are provided on the surface of the pressure block 203. The bottom of the sealed top plate 101 is fixedly provided with an extrusion pipe 205 corresponding to the pressure block 203, and a discharge pipe 206 is provided on one side of the box body 1. The extrusion pipe 205 is connected to the discharge pipe 206. A motion conversion unit is provided between the drive base 201 and the rotating shaft 202, which is used to drive the rotating shaft 202 and the pressure block 203 to rotate when the drive base 201 reciprocates. A sealed discharge assembly controlled by the motion of the drive seat 201 is provided at the discharge pipe 206; The core of this solution lies in the innovative installation of an extrusion mechanism before filtration. Its direct benefit is to solve the problem of easy clogging of filtration equipment in river water treatment. The drive seat 201 drives the pressure block 203 to rotate and extrude and pre-dehydrate the intercepted impurities in the extrusion tube 205. This can compact loose, high-moisture-content debris (such as leaves and fibers) into blocks, greatly reducing the impurity load and adhesion risk that subsequently enter the filter element body 102. This significantly extends the filter element cleaning or replacement cycle and improves the continuity and stability of equipment operation. At the same time, the entire pretreatment, extrusion, and discharge process is automatically triggered and coordinated by the movement of the same drive seat 201, resulting in a compact structure and a high degree of automation. The specific principle is as follows: water enters the squeezing pipe 205 through the water inlet pipe 9, impurities are intercepted, the drive seat 201 reciprocates under the drive, and drives the rotating shaft 202 and the pressure block 203 to rotate in the squeezing pipe 205 through the motion conversion unit to squeeze and dehydrate the impurities. At the same time, the movement of the drive seat 201 controls the opening and closing of the discharge pipe 206 through the sealing discharge assembly to realize automatic slag discharge.

[0018] The motion conversion unit includes a diagonal rod 3 fixedly installed on the inner wall of the housing 1, a connecting block 301 slidably sleeved on the diagonal rod 3, a rack 302 rotatably connected to the connecting block 301 and slidably engaged with the drive seat 201, and a gear 303 fixedly sleeved on the rotating shaft 202, the gear 303 meshing with the rack 302; This scheme specifies the structure of the motion conversion unit. By using the fixed inclined track of the inclined bar 3, the linear motion of the drive seat 201 is reliably converted into the reciprocating rotational motion of the pressure block 203 through the meshing of the connecting block 301, rack 302 and gear 303. Its beneficial effect is that the conversion mechanism is purely mechanically linked, without the need for an additional rotational power source. It has a direct response, precise transmission and low failure rate. It cleverly converts a linear input into a composite output that includes both linear propulsion and rotational extrusion, ensuring the effectiveness of the impurity dehydration and extrusion action. The principle is as follows: Since the rack 302 is connected to the fixed inclined rod 3 through the connecting block 301, the rack 302 is forced to move along the inclined rod 3 when moving horizontally, thereby driving the gear 303 that meshes with it to rotate in both directions, and finally driving the pressure block 203 to achieve the rotational extrusion action.

[0019] The reciprocating motion of the drive unit 201 is driven by the drive assembly; The drive assembly includes a drive member 4 fixedly mounted on the sealed top plate 101, a cam 401 driven by the output shaft of the drive member 4, and a slider 402 rotatably connected to the cam 401. A T-shaped transmission plate 403 is fixedly connected to the drive base 201, and a slider 402 is slidably disposed in the groove of the T-shaped transmission plate 403. This solution defines the specific composition of the drive assembly. A drive component 4 (such as a motor) drives the cam 401 to rotate. The cam 401 then slides through the slide of the slider 402 in the groove of the T-shaped transmission plate 403, converting the rotational motion into a smooth reciprocating linear motion of the drive seat 201. The advantages are that the power transmission path is clear, the cooperation between the cam 401 and the T-shaped transmission plate 403 can provide a stable and reliable reciprocating drive, and the design of the profile of the cam 401 can easily control the stroke, speed and timing of the drive seat 201, providing a precise power foundation for all subsequent coordinated actions (extrusion, discharge, cleaning). The principle is as follows: the drive unit 4 starts, drives the cam 401 to rotate, pushes the slider 402, and the slider 402 slides in the groove of the T-shaped transmission plate 403, thereby converting the rotational motion of the cam 401 into the precise reciprocating linear motion of the drive seat 201 along the bracket 2.

[0020] A filter box 5 is slidably connected inside the housing 1. The filter element body 102 is set inside the filter box 5. A filter plate 501 is detachably installed on the top of the filter box 5. Multiple elastic elements b502 are fixedly connected inside the housing 1. A pressure plate 503 is fixedly connected to one end of the elastic element b502. The bottom of the pressure plate 503 is in contact with the surface of the filter plate 501. The drive base 201 is also connected to a self-cleaning unit that is in drive with the filter box 5, which is used to drive the filter box 5 and the filter element body 102 to vibrate when the drive base 201 reciprocates. This solution introduces a sliding filter box 5 and a self-cleaning unit. Its direct benefit is the automatic cleaning of the filter element body 102. By placing the filter element body 102 in the filter box 5 and using the reciprocating motion of the drive seat 201 as a vibration source, adhering substances on the filter element surface can be continuously shaken off, effectively alleviating deep clogging of the filter element and further ensuring filtration efficiency and extending filter element life. Furthermore, the sliding connection of the filter box 5 and the detachable design of the filter plate 501, combined with the elastic clamping provided by the elastic element b502 and the pressure plate 503, ensure both sealing during filtration and greatly facilitate the maintenance and replacement of the filter element. The principle is as follows: the movement of the drive seat 201 drives the filter box 5 to vibrate through the self-cleaning unit, thereby cleaning the filter element body 102. During maintenance, the entire filter box 5 can be pulled out by disassembling the inspection plate.

[0021] The self-cleaning unit includes a corrugated plate 6 symmetrically fixed to the bottom of the filter box 5, and a mating rod 601 fixed to the drive seat 201. A ball bearing 602 is rotatably connected to the end of the mating rod 601, and the ball bearing 602 contacts the corrugated surface of the corrugated plate 6. This solution discloses a highly efficient method for implementing a self-cleaning unit. It uses a corrugated plate 6 in conjunction with a mating rod 601 with ball bearings 602. The beneficial effect is that it can smoothly and with low resistance convert the linear motion of the drive seat 201 into the up-and-down vibration of the filter box 5. The curved contact between the ball bearings 602 and the corrugated plate 6 results in low friction and high transmission efficiency. Furthermore, the amplitude and frequency of the generated vibration can be adjusted by the design of the crests and troughs of the corrugated plate 6, achieving gentle and effective cleaning of the filter element and avoiding potential damage to the filter element structure caused by severe vibration. The principle is as follows: the mating rod 601 fixed on the drive seat 201 drives the ball 602 at its end to roll along the curved surface of the wave plate 6 at the bottom of the filter box 5, thereby converting the linear motion into the up and down vibration of the filter box 5.

[0022] The sealing discharge assembly includes a T-shaped sealing plate 701 slidably disposed on one side of the housing 1 via a guide rod 7, an elastic element a702 for applying an elastic sealing force to the T-shaped sealing plate 701, and a pressure rod 703 fixedly connected at one end to the T-shaped sealing plate 701. A pushing component is connected to the drive seat 201, which is used to push the pressure rod 703 during the stroke of the pressure block 203 to perform the discharge action, so that the T-shaped sealing plate 701 overcomes the elastic force of the elastic element a702 and opens the discharge pipe 206. This solution specifies the structure of the sealing discharge assembly. Through the cooperation of the T-shaped sealing plate 701, the elastic element a702, and the pressure rod 703, the normally closed sealing and controlled opening of the discharge pipe 206 are achieved. Its beneficial effect is that during non-discharge periods, the elastic force of the elastic element a702 can ensure that the T-shaped sealing plate 701 tightly seals the discharge pipe 206 to prevent water leakage during processing. During discharge, the opening is triggered by pushing the component. This structure is simple and reliable, has a good sealing effect, and the opening and closing action is automatically synchronized with the extrusion discharge stroke, without the need for separate control. The principle is as follows: when material needs to be discharged, the pushing component pushes the pressure rod 703, causing the T-shaped sealing plate 701 to compress the elastic element a702 and slide along the guide rod 7, opening the discharge pipe 206. After the material is discharged, the elastic element a702 causes the T-shaped sealing plate 701 to reset and seal.

[0023] The pushing component includes an L-shaped push rod 8 fixed to the bottom of the drive seat 201. A limiting groove 801 is provided at the bottom of the bracket 2. The L-shaped push rod 8 is slidably disposed in the limiting groove 801 and can contact and push the pressure rod 703 when the drive seat 201 moves to a specific position. This design defines the specific structure of the pushing component as the cooperation between the L-shaped push rod 8 and the limiting groove 801. Its beneficial effect is that it provides a precise and reliable mechanical triggering mechanism. The L-shaped push rod 8 moves with the drive seat 201, and the limiting groove 801 ensures its movement trajectory. Only when the drive seat 201 (and the pressure block 203) moves to the "specific position" where material discharge is required, the L-shaped push rod 8 contacts and pushes the pressure rod 703. This design achieves a strict interlock between the material discharge action and the extrusion process, avoids malfunctions, and ensures that the discharge pipe 206 is only opened after the impurities have been fully extruded and dehydrated. The principle is as follows: the L-shaped push rod 8 fixed to the bottom of the drive seat 201 slides in the limiting groove 801, contacts and pushes the pressure rod 703 at the predetermined position, thereby triggering the opening of the discharge pipe 206.

[0024] The top of the sealed top plate 101 is provided with a water inlet pipe 9, which is connected to the squeezing pipe 205. The other side of the box body 1 is provided with a drain pipe 901. This plan clarifies the installation of inlet pipe 9 and outlet pipe 901. Its beneficial effects are mainly reflected in the engineering practicality and integrability of the equipment. The standard pipe interface (usually equipped with flanges) makes it very convenient to connect the equipment to the river pumping system and water return system, which facilitates rapid installation and deployment in various treatment projects, and improves the modularity and on-site adaptability of the equipment. The principle is as follows: the water to be treated is introduced through the inlet pipe 9, and the purified water is discharged through the drain pipe 901.

[0025] The working principle of this river water treatment equipment is as follows: its core lies in the simultaneous completion of pretreatment and dehydration of impurities, automatic slag discharge, and cleaning and anti-clogging of the filter element through an integrated mechanical drive structure, thereby achieving efficient and continuous filtration and treatment of river water. Specifically: The river water to be treated enters the equipment through the inlet pipe 9 (which is usually equipped with a flange at the end for easy connection to an external water pump pipe). The water first flows into the squeezing pipe 205 fixed at the bottom of the sealed top plate 101. The squeezing pipe 205 serves as a pretreatment chamber, and its inner wall intercepts impurities such as suspended solids, fibers, and fine debris carried in the water, thus initially achieving solid-liquid separation. The drive unit 4 (usually a motor) is started, driving the cam 401 on its output shaft to rotate. The rotation of the cam 401 pushes the slider 402 that is rotatably connected to it. The slider 402 is nested in the groove of the T-shaped transmission plate 403 fixed on the drive seat 201, thereby converting the rotational motion of the cam 401 into the precise reciprocating linear motion of the drive seat 201 along the bracket 2. The reciprocating motion of the drive unit 201 simultaneously triggers two key action chains: Action Chain 1 (Rotational Extrusion): The movement of the drive seat 201 causes the rack 302, which is slidably engaged with it, to produce a horizontal displacement. Since the rack 302 is slidably connected to the inclined rod 3 fixed to the inner wall of the box 1 through the connecting block 301, this horizontal displacement is converted into a composite motion with horizontal and vertical components by the guiding action of the inclined rod 3. This motion of the rack 302 drives the gear 303 meshing with it to rotate in both directions. The gear 303 is fixedly sleeved on the rotating shaft 202, which in turn drives the rotating shaft 202 and the pressure block 203 fixed at its end to reciprocate in the extrusion tube 205. The multiple drainage holes 204 on the surface of the pressure block 203 ensure that when it rotates and extrudes the impurities, the water can be effectively squeezed out and flow back from the holes, thereby achieving the concentration and dehydration of the impurities and forming a relatively dense impurity block. Action Chain 2 (Opening of Discharge Pipe 206): When the drive seat 201 moves to a specific stage of its stroke (when the pressure block 203 completes the squeezing and pushes the dehydrated impurity block towards the outlet of the discharge pipe 206), the L-shaped push rod 8 fixed to the bottom of the drive seat 201 moves accordingly. The L-shaped push rod 8 slides in the limiting groove 801 opened at the bottom of the bracket 2 and contacts and pushes the pressure rod 703 at a predetermined position. After the pressure rod 703 is subjected to force, it drives the T-shaped sealing plate 701 fixedly connected to it to compress the elastic element a702 along the guide rod 7 and slide, thereby automatically opening the discharge port of the discharge pipe 206. As the pressing block 203 continues to advance, the dehydrated and compressed impurity block is pushed out of the extrusion pipe 205 and discharged outside the equipment through the opened discharge pipe 206. When the drive seat 201 begins to return, the L-shaped push rod 8 disengages from the pressure rod 703, and the T-shaped sealing plate 701 automatically returns to its original position under the reset elastic force of the elastic element a702, resealing the discharge pipe 206 to prevent untreated water from being discharged. Synchronous with the above process, the reciprocating linear motion of the drive seat 201 also drives the filter structure to vibrate through the self-cleaning unit. The mating rod 601 fixed on the drive seat 201 reciprocates accordingly, and the ball bearing 602 rotatably connected to its end rolls along the wave-shaped curved surface of the wave plate 6 symmetrically fixed at the bottom of the filter box 5. This design converts the smooth linear motion of the drive seat 201 into continuous and gentle up-and-down vibration of the filter box 5. The filter element body 102 is placed inside the filter box 5, and its top is covered by the filter plate 501. The filter plate 501 is pressed by the pressure plate 503 supported by multiple elastic elements b502. Therefore, the vibration of the filter box 5 is effectively transmitted to the filter element body 102 inside, which can continuously shake off the sticky particles and flocs attached to its surface and pores, significantly reducing filter element clogging and maintaining its filtration capacity. The clean water, pretreated by the squeezing pipe 205 and having most of its impurities removed, enters the main chamber of the housing 1 from the outlet of the squeezing pipe 205. It then flows downwards through the vibrating filter box 5 and filter element body 102. Here, residual fine suspended solids in the water are deeply trapped, achieving purification. The purified water collects at the bottom of the housing and is finally discharged from the equipment through the drain pipe 901 located on the other side of the housing 1 (which also has a flange at its end for easy connection to subsequent pipelines or return channels). For ease of long-term maintenance, when it is necessary to inspect or replace the filter element body 102, the inspection plate located on the side wall of the housing 1 and corresponding to the internal filter box 5 can be removed. After removal, the filter box 5 can be directly pulled out from the slide rail of the housing 1. There is ample operating space and maintenance is convenient. In addition, the standard flanges on the inlet pipe 9 and the drain pipe 901 ensure that the equipment can be quickly and reliably connected to the external water supply and outlet pipes, improving the engineering applicability and installation efficiency of the equipment.
