Description

Technical Field

[0001] This invention relates to the field of water purification technology, and in particular to a multifunctional in-situ river management ecosystem using water purification fillers. Background Technology

[0002] With the acceleration of urbanization and the increase in industrial activities, the problem of river water pollution is becoming increasingly serious. Traditional water purification technologies have many shortcomings in terms of treatment efficiency, maintenance costs, and ease of operation. In the field of water purification technology, biological packing methods are widely used due to their advantages such as low cost and environmental friendliness. However, existing packing systems require shutdown and disassembly for packing replacement, which affects continuous operation efficiency. The coordination between multi-stage purification units is poor, making it difficult to achieve tiered removal of pollutants. Furthermore, the degree of automation is low, and packing cleaning and maintenance rely on manual operation, which is labor-intensive and the effect is unstable. In addition, traditional equipment mostly adopts a centralized treatment mode, which requires the construction of dedicated sites and water pipelines, and cannot meet the needs of decentralized in-situ river treatment. Therefore, this invention provides a multifunctional in-situ river treatment ecosystem using water purification packing. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a multifunctional in-situ river management ecosystem using water purification fillers. It overcomes the problems that the replacement of purification fillers often requires interrupting system operation, resulting in high maintenance costs, low efficiency, and the need to transfer water to centralized treatment facilities.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional in-situ river remediation ecosystem using water purification filler, comprising a base plate, on which a treatment component and a replacement component are disposed. The treatment component includes a support frame, on which multiple semi-circular shells are uniformly fixed. A semi-circular screen plate is rotatably mounted on each semi-circular shell, and a sealing square plate is fixedly disposed on the end face of each semi-circular screen plate. A treatment chamber is formed between the corresponding semi-circular shells, sealing square plates, and semi-circular screen plates.

A storage chamber is formed between the corresponding semi-circular ring plate, the sealing square plate, and the semi-circular screen plate. A semi-circular toothed ring is fixedly set on each semi-circular screen plate, and a switching gear is rotatably mounted on the semi-circular ring plate. When the switching gear and the semi-circular toothed ring are engaged, they form a gear pair. The switching gear is used to switch between the semi-circular shell and the semi-circular screen plate on the semi-circular ring plate.

There are no gaps between the semi-circular shell and the conical drain pipe and the adjacent processing chambers. A water injection pipe is fixedly installed on the semi-circular cover plate, and a drain square hole is provided on the bottom plate.

[0007] Furthermore, the locking unit includes multiple semi-circular strips, which are slidably mounted on corresponding semi-circular shells. Arc-shaped blocks are symmetrically fixed on the semi-circular strips, and arc-shaped slots that cooperate with the arc-shaped blocks are symmetrically arranged on the semi-circular toothed rings. The arc-shaped blocks are used to fix the semi-circular shells and the corresponding semi-circular screen plates.

[0008] Furthermore, the locking unit also includes a locking slide plate that is slidably mounted on the base plate. Multiple locking strips are fixedly mounted on the locking slide plate. Locking short rods are symmetrically fixedly mounted on the locking strips. Locking blocks are symmetrically fixedly mounted on the semi-circular strips. The locking blocks are provided with through holes that cooperate with the locking short rods. The locking short rods and locking blocks are used to lock the position of the semi-circular strips.

[0009] Furthermore, the Z-shaped slide plate is slidably mounted on the base plate, and an adjustment screw is provided between the Z-shaped slide plate and the base plate. A feed screw is provided between the replacement slide and the replacement rotating frame. When the end faces of the two semi-circular screen plates are joined, a complete circular screen plate is formed. When the end faces of the two semi-circular toothed rings are joined, a complete toothed ring is formed.

[0010] Furthermore, a semi-circular baffle is slidably mounted on the replacement carriage to cover the storage chamber. An auxiliary rack two is fixedly mounted on the semi-circular baffle. An auxiliary rack one is fixedly mounted on the replacement carriage. An auxiliary gear is rotatably mounted on the replacement carriage.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example: Reference Figures 1-10 A multifunctional in-situ river remediation ecosystem using water purification filler includes a base plate 101. A treatment component is installed on the base plate 101. The treatment component includes a support frame 105, which is fixedly installed on the base plate 101. Multiple semi-circular shells 120 are uniformly fixed on the support frame 105. The axes of the semi-circular shells 120 are on the same straight line and are perpendicular to the lower surface of the base plate 101. A semi-circular screen plate 140 is rotatably installed on each of the semi-circular shells 120. A sealing square plate 136 is fixedly installed on the end face of each semi-circular screen plate 140. Treatment chambers are formed between the corresponding semi-circular shells 120, sealing square plates 136, and semi-circular screen plates 140. The projections of the multiple treatment chambers on the lower surface of the base plate 101 coincide, and there are no gaps between two adjacent treatment chambers.

[0027] A semi-circular cover plate 121 and a conical drain pipe 141 are also fixedly installed on the support frame 105. The semi-circular cover plate 121 is located above the semi-circular shell 120 that is furthest from the lower surface of the bottom plate 101, and the conical drain pipe 141 is located below the semi-circular shell 120 that is closest to the lower surface of the bottom plate 101. There are no gaps between the semi-circular shell 120 and the conical drain pipe 141 and the adjacent treatment chambers. The semi-circular shell 120, the conical drain pipe 141 and the multiple treatment chambers form a complete water purification chamber. A water injection pipe 109 is fixedly installed on the semi-circular cover plate 121. A drain square hole 104 is provided on the bottom plate 101. The lower end of the conical drain pipe 141 is located directly above the drain square hole 104. A treatment water pump 107 is fixedly installed on the bottom plate 101. The treatment water pump 107 and the water injection pipe 109 are connected by a pipe.

[0028] Multiple storage cabinets 103 are fixedly installed on the base plate 101. The multiple storage cabinets 103 are used to store various purification packing materials, and multiple processing chambers are used to place different purification packing materials.

[0029] When purifying water, water is drawn from the river by the water pump 107 and injected into the water purification chamber through the water injection pipe 109. The river water enters the water purification chamber and passes through multiple treatment chambers from top to bottom. The purification packing material placed on the semi-circular screen plate 140 in the treatment chamber is used to purify the river water. The purified water is discharged from the conical drain pipe 141 and falls back into the river through the drain square hole 104. The device is set on the side of the river, thereby realizing in-situ river treatment.

[0030] A locking unit is provided on the support frame 105. The locking unit is used to limit the position of the sealing square plate 136 on the semi-circular shell 120. The locking unit includes multiple semi-circular strips 134. The semi-circular strips 134 are slidably installed on the corresponding semi-circular shells 120. A spring is provided between the semi-circular strips 134 and the corresponding semi-circular shells 120. Arc-shaped strips 142 are symmetrically fixed on the semi-circular strips 134. Semi-circular toothed rings 128 are fixedly installed on the outer side of the semi-circular screen plate 140. The axes of the semi-circular toothed rings 128 and the corresponding semi-circular screen plates 140 are on the same straight line. Arc-shaped slots that cooperate with the arc-shaped strips 142 are symmetrically provided on the semi-circular toothed rings 128. The arc-shaped strips 142 are used to fix the semi-circular shells 120 and the corresponding semi-circular screen plates 140.

[0031] When the end faces of the two semicircular sieve plates 140 are joined, a complete circular sieve plate is formed; when the end faces of the two semicircular toothed rings 128 are joined, a complete toothed ring is formed.

[0032] In the initial position, the springs between the semicircular strip 134 and the semicircular shell 120 are not compressed. At this time, the arc-shaped strip 142 and the arc-shaped slot on the corresponding semicircular toothed ring 128 are in an engaged state. Under the action of the arc-shaped strip 142, the semicircular toothed ring 128 corresponding to the arc-shaped strip 142 cannot rotate relative to the semicircular shell 120, that is, the semicircular screen plate 140 corresponding to the arc-shaped strip 142 cannot rotate relative to the semicircular shell 120.

[0033] When it is necessary for the semicircular screen plate 140 to rotate, the semicircular strip plate 134 is pushed upward, the spring between the semicircular strip plate 134 and the corresponding semicircular shell 120 is compressed, and the arc-shaped strip 142 on the semicircular strip plate 134 moves upward synchronously, eventually causing the arc-shaped strip 142 to disengage from the corresponding semicircular toothed ring 128, that is, to release the restriction on the semicircular toothed ring 128, and then the semicircular screen plate 140 can rotate freely.

[0034] The locking unit also includes a locking slide plate 117 slidably mounted on the base plate 101. A locking electric cylinder 106 is fixedly mounted on the base plate 101. The piston rod end of the locking electric cylinder 106 is fixedly connected to the locking slide plate 117. Multiple locking strips 137 are fixedly provided on the locking slide plate 117. The number of locking strips 137 is the same as the number of semi-circular shells 120. Locking short rods 138 are symmetrically fixedly provided on the locking strips 137. Locking blocks 139 are symmetrically fixedly provided on the semi-circular strips 134. The locking blocks 139 are provided with through holes that cooperate with the locking short rods 138. The locking short rods 138 and the locking blocks 139 are used to lock the position of the semi-circular strips 134.

[0035] In the initial position, the locking slide plate 117 is located closest to the semi-circular shell 120. At this time, the locking short rods 138 are engaged with the through holes on the corresponding locking blocks 139. Under the action of the locking short rods 138 and the locking blocks 139, the semi-circular strip 134 cannot move up and down relative to the semi-circular shell 120, thus locking the position of the semi-circular strip 134, thereby locking the position of the corresponding semi-circular screen plate 140 again.

[0036] When it is necessary to move the semi-circular screen plate 140, first activate the locking electric cylinder 106 to move the locking slide plate 117 away from the semi-circular shell 120. The locking strips 137 on the locking slide plate 117 move synchronously, and the locking short rods 138 on the locking strips 137 also move synchronously. Finally, the locking short rods 138 disengage from the locking block 139, that is, the locking short rods 138 release the restriction on the position of the semi-circular strip plate 134.

[0037] A replacement assembly is provided on the base plate 101. The replacement assembly includes a Z-shaped slide plate 110, which is slidably mounted on the base plate 101. A height adjustment screw 111 is provided between the Z-shaped slide plate 110 and the base plate 101. The height adjustment screw 111 is rotatably mounted on the base plate 101. The height adjustment screw 111 and the Z-shaped slide plate 110 form a helical pair. A height adjustment motor 112 is fixedly mounted on the base plate 101. The output shaft of the height adjustment motor 112 is fixedly connected to the height adjustment screw 111. When the height adjustment motor 112 is started, it drives the height adjustment screw 111 to rotate, which allows the Z-shaped slide plate 110 to move up and down relative to the base plate 101.

[0038] A replacement frame 118 is rotatably mounted on a Z-shaped slide plate 110. A tilting motor 119 is also fixedly mounted on the Z-shaped slide plate 110. The output shaft of the tilting motor 119 is fixedly connected to the replacement frame 118. A replacement slide 122 is slidably mounted on the replacement frame 118. A feed screw 124 is provided between the replacement slide 122 and the replacement frame 118. The feed screw 124 is rotatably mounted on the replacement frame 118. The feed screw 124 and the semi-circular cover plate 121 form a helical pair. A feed motor 125 is also fixedly mounted on the replacement frame 118. The output shaft of the feed motor 125 is fixedly connected to the feed screw 124. When the feed motor 125 is started, it drives the feed screw 124 to rotate, so that the replacement slide 122 moves along the axis of the feed screw 124.

[0039] A semi-circular ring plate 123 is fixedly installed on the replacement slide 122. A spare semi-circular sieve plate 140 is rotatably installed on the semi-circular ring plate 123. A storage chamber is formed between the corresponding semi-circular ring plate 123, sealing square plate 136, and semi-circular sieve plate 140. A switching gear 129 is rotatably installed on the semi-circular ring plate 123. When the switching gear 129 and the semi-circular toothed ring 128 are engaged, they form a gear pair. The switching gear 129 is used to switch between the semi-circular shell 120 and the semi-circular sieve plate 140 on the semi-circular ring plate 123. A switching motor 130 is also fixedly installed on the semi-circular ring plate 123. The output shaft of the switching motor 130 is fixedly connected to the switching gear 129.

[0040] The height adjustment motor 112 is started to adjust the position of the Z-shaped slide plate 110, so that the Z-shaped slide plate 110 moves to the same height as the processing chamber where the packing needs to be replaced. At this time, the replacement frame 118 is in a horizontal state under the action of the tilting motor 119. Then, the feed motor 125 is started to drive the replacement slide 122 to move away from the Z-shaped slide plate 110. The components on the replacement slide 122 move synchronously, so that the semi-circular screen plate 140 on the semi-circular ring plate 123 is engaged with the semi-circular screen plate 140 corresponding to the processing chamber where the packing needs to be replaced. At this time, the two semi-circular screen plates are engaged. The circular screen plates 140 are joined to form a complete circular screen plate, and the semicircular toothed rings 128 on the two semicircular screen plates 140 are joined to form a complete ring plate. The position restriction of the semicircular screen plate 140 is released by the control locking unit, and then the switching motor 130 is started to drive the switching gear 129 to rotate. Under the action of the switching gear 129, the toothed ring formed by the two semicircular toothed rings 128 rotates, so that the two semicircular screen plates 140 rotate synchronously, and finally the two semicircular screen plates 140 exchange positions, thereby realizing the replacement of the packing in the processing chamber where the packing needs to be replaced.

[0041] Waste screen frame 102 is fixedly installed on the base plate 101. After the packing is replaced, the Z-shaped slide plate 110 and the replacement slide 122 return to their initial positions. The tilting motor 119 is started to drive the replacement rotating frame 118 to rotate 180 degrees. The parts on the replacement rotating frame 118 rotate 180 degrees synchronously, thus tilting the packing on the semi-circular screen plate 140. The tilted waste packing falls into the waste screen frame 102 below.

[0042] A semi-circular baffle 127 is slidably mounted on the replacement slide 122. The semi-circular baffle 127 is used to cover the storage chamber. Under the action of the semi-circular baffle 127, contaminants are prevented from entering the packing in the storage chamber from above. An auxiliary rack 132 is fixedly mounted on the semi-circular baffle 127. An auxiliary rack 126 is fixedly mounted on the replacement frame 118. An auxiliary gear 131 is rotatably mounted on the replacement slide 122. Both the auxiliary rack 126 and the auxiliary rack 132 mesh with the auxiliary gear 131 to form a rack and pinion pair. The teeth of the auxiliary rack 126 and the auxiliary rack 132 face opposite directions.

[0043] When the changing carriage 122 is at its furthest position from the tilting motor 119, under the action of auxiliary rack 126, auxiliary gear 131, and auxiliary rack 132, the semi-circular baffle 127 is positioned directly above the semi-circular ring plate 123. At this time, the axes of the semi-circular baffle 127 and the semi-circular ring plate 123 are on the same straight line, meaning that the semi-circular baffle 127 covers the storage chamber on the semi-circular ring plate 123. As the changing carriage 122 moves towards the Z-shaped sliding plate 110, the auxiliary rack 126... Under the action of auxiliary gear 131 and auxiliary rack 132, the semi-circular baffle 127 moves towards the replacement slide 122 as the replacement slide 122 moves towards the Z-shaped slide plate 110. When the replacement slide 122 moves to the position closest to the Z-shaped slide plate 110, the semi-circular baffle 127 moves to the position closest to the replacement slide 122. At this time, the semi-circular baffle 127 removes the cover from the storage chamber on the semi-circular ring plate 123, thus facilitating the dumping of the replaced waste filler.

[0044] A trapezoidal push block 133 is symmetrically fixed on the semicircular ring plate 123, and a separation push block 135 is symmetrically fixed on the semicircular strip plate 134. The trapezoidal push block 133 and the separation push block 135 are used to adjust the position of the corresponding semicircular strip plate 134.

[0045] During the process of changing the slide 122 and moving it closer to the support frame 105, the trapezoidal push block 133 contacts the separation push block 135 on the corresponding semi-circular strip 134. Under the action of the trapezoidal push block 133 and the separation push block 135, the semi-circular strip 134 moves upward. When the semi-circular screen plate 140 on the semi-circular ring plate 123 engages with the corresponding semi-circular screen plate 140, under the action of the trapezoidal push block 133 and the semi-circular strip 134, the arc-shaped strip 142 on the semi-circular strip 134 releases the restriction on the position of the semi-circular screen plate 140.

[0046] A transverse sliding plate 115 is slidably mounted on the base plate 101. A transverse lead screw 114 is rotatably mounted on the base plate 101. The transverse lead screw 114 and the transverse sliding plate 115 form a helical pair. A transverse motor 113 is also fixedly mounted on the base plate 101. The output shaft of the transverse motor 113 is fixedly connected to the transverse lead screw 114. Multiple flushing nozzles 116 are evenly fixedly mounted on the transverse sliding plate 115. The flushing nozzles 116 are used to flush the purification packing on the semi-circular screen plate 140. Pipes are provided inside the transverse sliding plate 115. The flushing nozzles 116 are all connected to the pipes inside the transverse sliding plate 115. A cleaning water pump 108 is fixedly mounted on the base plate 101. A conduit is provided between the cleaning water pump 108 and the pipes inside the transverse sliding plate 115.

[0047] When the packing material in the processing chamber has a lot of impurities attached but does not yet meet the standard for disposal and replacement, the corresponding semi-circular sieve plate 140 and sealing square plate 136 of the processing chamber are transferred to the semi-circular ring plate 123 by replacing the components. Then, the semi-circular ring plate 123 is moved to the position closest to the Z-shaped slide plate 110. At this time, the semi-circular shielding plate 127 removes the cover from the packing material on the semi-circular ring plate 123. A clean water tank is also provided on the bottom plate 101. Then, the cleaning water pump 108 is started to draw water from the clean water tank and spray it from the flushing nozzle 116 to flush the packing material below. The transverse movement motor 113 is started to drive the transverse movement screw 114 to make the transverse movement slide plate 115 move laterally, thereby cleaning the packing material.

[0048] Working principle: Different purification packing materials are placed on the semi-circular screen plate 140 on the support frame 105. The water pump 107 draws river water and injects it into the water purification chamber through the water injection pipe 109. The water is purified by the purification packing materials in the continuous treatment chamber. The purified water falls through the screen gaps of the semi-circular screen plate 140 and is finally discharged from the conical drain pipe 141.

[0049] When it is necessary to clean the packing in the processing chamber, the processing chamber is transferred to the semi-circular ring plate 123 by replacing the components. At this time, the semi-circular screen plate 140 on the semi-circular ring plate 123 moves to engage with the semi-circular shell 120, and then the semi-circular baffle plate 127 removes its cover from the semi-circular ring plate 123. Then, by starting the cleaning water pump 108 and the transverse motor 113, the flushing nozzle 116 can flush the packing below.

[0050] When the packing in the processing chamber needs to be replaced, the required packing is taken out from the required storage cabinet 103, and then placed on the semi-circular screen plate 140 on the semi-circular ring plate 123. The semi-circular baffle plate 127 then covers the chamber on the semi-circular ring plate 123. The replacement assembly is then used to replace the semi-circular screen plate 140 and the semi-circular screen plate 140 in the processing chamber to be replaced, thereby replacing the packing. After the replacement is completed, the semi-circular ring plate 123 is moved to the position closest to the Z-shaped slide plate 110. At this time, the semi-circular baffle plate 127 is removed from covering the chamber on the semi-circular ring plate 123. Then, the tilting motor 119 is started to drive the replacement frame 118 to rotate, thereby tilting the packing on the semi-circular screen plate 140. After the tilting is completed, the chamber on the semi-circular ring plate 123 is flushed through the flushing nozzle 116, which facilitates the subsequent filling of the required replacement packing.

[0051] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
