Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, and in particular to a nutrient adsorption device for natural rubber processing wastewater. Background Technology

[0002] During the production and processing of natural rubber, process wastewater containing organic matter, suspended solids, and other nutrients is generated. In order to achieve sustainable resource utilization and environmental protection, a common approach is to recover the nutrients from this wastewater. At the same time, rubber production also generates a large amount of waste, such as sawdust. Using sawdust as a low-cost and widely available natural adsorbent material to filter wastewater, and then using the nutrient-adsorbed sawdust as a raw material for organic fertilizer, is a highly promising resource utilization method.

[0003] Traditional filtration methods often involve static soaking or single-pass filtration. In these modes, the contact time between wastewater and the sawdust filling layer is short, and the flow channel is singular, resulting in the sawdust's adsorption capacity not being fully utilized. Consequently, the nutrient removal rate in the wastewater is low, and the overall treatment efficiency is inefficient. Furthermore, in actual production, the nutrient concentration, suspended solids content, and other indicators of different batches of wastewater often fluctuate. Existing filtration equipment typically uses fixed filtration intensities (such as fixed water flow rates or pressures), which cannot be flexibly adjusted according to the actual conditions of the wastewater. When treating high-concentration wastewater, insufficient filtration intensities may lead to substandard treatment results; while when treating low-concentration wastewater, excessive filtration intensities may cause unnecessary energy waste, resulting in a lack of flexibility in process adjustment. Utility Model Content

[0004] The purpose of this invention is to provide a novel wastewater nutrient adsorption device that can not only significantly improve filtration and adsorption efficiency, but also flexibly adjust its operating parameters according to different working conditions to achieve the best treatment effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a nutrient adsorption device for natural rubber processing wastewater, comprising a support plate, on which a first filter box and a second filter box are installed side by side, each filter box having four water supply pipes on its sidewall, and two one-way check valves on the water supply pipes on the adjacent side of the two filter boxes, the lower one-way check valve allowing wastewater to flow from the second filter box to the first filter box, and the upper one-way check valve allowing wastewater to flow from the first filter box to the second filter box; Both the first and second filter boxes are equipped with filter components, which include a floating filter box and a pressing filter box that can move up and down. Both filter boxes are filled with a sawdust filling layer, and the surface of both filter boxes and the cover plate at the opening end are equipped with water inlet holes. The support plate is equipped with a drive mechanism for driving the filter assembly to reciprocate, and an adjustment mechanism for adjusting the stroke of the filter assembly.

[0006] As a further description of the above technical solution: both the floating filter box and the pressing filter box are provided with a frame and a flap that slides within the frame; The frame of the floating filter box is located above the opening end. The flap opens when it moves downward and closes when it moves upward. The retaining frame of the pressure filter box is located below the opening end. The flap opens when it moves upward and closes when it moves downward.

[0007] As a further description of the above technical solution: the driving mechanism includes a drive motor fixed to the support plate and a turntable fixed to the output shaft of the drive motor, with a drive rod eccentrically fixed to the turntable; A reciprocating rod is rotatably mounted on the support plate. The reciprocating rod has strip holes at both ends and a rectangular hole in the middle. The end of the drive rod is slidably connected to the rectangular hole.

[0008] As a further description of the above technical solution: the adjustment mechanism includes two connecting rods that vertically penetrate the top walls of the first filter box and the second filter box, and the two connecting rods are fixedly connected to the floating filter box and the pressing filter box respectively; The support plate has two sliding lifting plates, and the two lifting plates are respectively fixedly connected to two connecting rods; Each lifting platform is equipped with an electric push rod, and the telescopic end of the electric push rod is connected to a sliding component; The end of the slider extends into the strip hole and is slidably connected thereto.

[0009] As a further description of the above technical solution: the telescopic movement of the electric push rod changes its position in the slot through the sliding member, thereby adjusting the up-and-down reciprocating stroke of the floating filter box and the pressing filter box.

[0010] As a further description of the above technical solution: the reciprocating swing of the reciprocating rod drives the lifting plate through the sliding member, so that the floating filter box and the pressing filter box move synchronously in opposite directions: When the floating filter box moves downward to filter, the pressure filter box moves upward to filter; when the floating filter box moves upward to push water, the pressure filter box moves downward to push water.

[0011] As a further description of the above technical solution: the sawdust filling layer is composed of waste sawdust generated during the rubber production process, forming a porous adsorption structure.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. By setting up a first filter box and a second filter box, and incorporating a floating filter box and a pressure filter box capable of reciprocating motion, and with the directional flow guidance of a one-way check valve, a wastewater circulation filtration system is constructed. In this system, wastewater is forced to repeatedly pass through the sawdust filling layer, which greatly increases the contact time and opportunities between the wastewater and the adsorption material, allowing the adsorption potential of the sawdust to be deeply explored, thereby significantly improving the adsorption efficiency and treatment effect of nutrients in the wastewater.

[0013] 2. By controlling the electric push rod, the operator changes the position of the sliding part in the reciprocating rod slot. According to the lever principle, the change in position can adjust the up and down reciprocating stroke of the filter component, that is, the vertical movement distance. This design enables the equipment to adjust the filtration intensity. The operator can flexibly set the most suitable operating parameters according to the real-time concentration of wastewater, treatment volume requirements, or different process stages. It has strong adaptability to working conditions and operational flexibility. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a nutrient adsorption device for natural rubber processing wastewater, including a support plate 10, which provides a stable installation platform for the entire device. On the support plate 10, a first filter box 11 and a second filter box 12 are installed side by side. The first filter box 11 and the second filter box 12 are the main containers for containing and treating wastewater.

[0018] To achieve the circulation of wastewater between the first filter box 11 and the second filter box 12, two water supply pipes 13 are provided on the side walls of both the first filter box 11 and the second filter box 12, one located at the top and one at the bottom. The two adjacent water supply pipes 13 of the first filter box 11 and the second filter box 12 are connected by two one-way check valves 14. The one-way check valve 14 at the bottom allows wastewater to flow from the second filter box 12 to the first filter box 11, while the one-way check valve 14 at the top allows wastewater to flow from the first filter box 11 to the second filter box 12, thus forming a one-way circulation loop.

[0019] Both the first filter box 11 and the second filter box 12 are equipped with filter components that can move up and down. The filter components are the core part for nutrient adsorption. The filter components include an upward-floating filter box 15 and a downward-pressing filter box 16. The upward-floating filter box 15 is located in the first filter box 11, and the downward-pressing filter box 16 is located in the second filter box 12.

[0020] Both the floating filter box 15 and the pressure filter box 16 are filled with sawdust filling layer 17. The sawdust filling layer 17 is preferably made of waste sawdust generated during the rubber production process. It is not only inexpensive and realizes the resource utilization of waste, but its porous structure can also effectively adsorb suspended solids, organic matter and other nutrients in wastewater.

[0021] To allow water to flow through while preventing sawdust leakage, both the floating filter box 15 and the pressure filter box 16 are equipped with cover plates 18 with several water inlets at their openings. The surfaces of the floating filter box 15 and the pressure filter box 16 away from the cover plates 18 are also provided with several water inlets.

[0022] The key structure for achieving unidirectional filtration in the floating filter box 15 and the pressure filter box 16 lies in their external frame 19 and flap 20. The frame 19 of the floating filter box 15 is installed above its opening end, while the frame 19 of the pressure filter box 16 is installed below its opening end. Both frames 19 are equipped with flaps 20 that can move under liquid pressure.

[0023] For the floating filter box 15, when it moves downward, the liquid pressure pushes open the flap 20, allowing wastewater to pass through the floating filter box 15; when it moves upward, the liquid pressure closes the flap 20, forming a sealed surface to push water upward.

[0024] For the pressure filter box 16, the working method is the opposite. When it moves upward, the flap 20 opens to allow water to flow through; when it moves downward, the flap 20 closes to form a sealing surface to press water downward.

[0025] In order to drive the movement of the floating filter box 15 and the pressing filter box 16, a connecting rod 21 is fixedly connected to the top of the frame 19 of the floating filter box 15 and the top wall of the pressing filter box 16. The connecting rod 21 passes vertically upward through the top walls of the first filter box 11 and the second filter box 12, and is connected to the driving component and the adjusting component above.

[0026] At the top of the support plate 10, there are drive components and adjustment components for driving and controlling the movement stroke of the filter components.

[0027] The adjustment assembly includes two lifting plates 22 that can slide up and down along the support plate 10. Specifically, the lifting plates 22 are slidably connected to the slide grooves on the support plate 10 via sliders. Each lifting plate 22 corresponds to and is fixed with a connecting rod 21. Each lifting plate 22 is also equipped with an electric push rod 23. The telescopic end of the electric push rod 23 is connected to a sliding member 24. By controlling the telescopic extension of the electric push rod 23, the position of the sliding member 24 can be changed.

[0028] The drive assembly includes a drive motor 25 fixed on a support plate 10. A turntable 26 is fixed to the output shaft end of the drive motor 25. A drive rod 261 is eccentrically fixed on the turntable 26. A reciprocating rod 27 is also rotatably mounted on the support plate 10. The reciprocating rod 27 has a pivot at its center and has slotted holes 271 at both ends. The ends of two sliding members 24 extend into these two slotted holes 271 and can slide within them. A rectangular hole 272 is provided between the rotation center of the reciprocating rod 27 and one of the slotted holes 271. The end of the drive rod 261 is slidably connected to the rectangular hole 272.

[0029] Work steps: Start the drive motor 25, which drives the turntable 26 to rotate. Since the drive rod 261 is eccentrically mounted, one end of the drive rod 261 moves in the rectangular hole 272, thereby pushing the reciprocating rod 27 to reciprocate in a fan-shaped swing with its center as the fulcrum. This swing causes the other end of the reciprocating rod 27 to move downward when one end moves upward.

[0030] The swing of the reciprocating rod 27 drives the lifting plate 22 and the connecting rod 21 through the sliding member 24 in the strip hole 271, thereby driving the floating filter box 15 and the pressing filter box 16 to perform up-and-down reciprocating motions in opposite directions.

[0031] When the floating filter box 15 moves downward to filter, the pressing filter box 16 moves upward to filter; when the floating filter box 15 moves upward to push the filtered liquid into the second filter box 12, the pressing filter box 16 moves downward to push the filtered liquid into the first filter box 11.

[0032] With the help of two one-way check valves 14, the wastewater forms a circulation flow between the two filter boxes. During this circulation process, the wastewater is repeatedly passed through the sawdust filling layer 17, so that the nutrients in the wastewater can be fully and efficiently adsorbed.

[0033] One of the key advantages of this device is that its filtration intensity can be adjusted, which can be extended or shortened by the operator by controlling two electric push rods 23.

[0034] When the electric push rod 23 is activated, it will drive the sliding member 24 to move within the strip hole 271 of the reciprocating rod 27. According to the lever principle, the farther the sliding member 24 is from the rotation center of the reciprocating rod 27, the greater its vertical distance of swing (i.e., stroke); conversely, the closer the sliding member 24 is to the rotation center, the smaller its stroke.

[0035] Therefore, by adjusting the position of the sliding component 24, the vertical movement distance of the two filter boxes can be precisely adjusted. This allows the operator to flexibly adjust the filtration intensity and circulation speed according to the concentration of wastewater, treatment volume requirements, or different treatment stages, in order to achieve the best adsorption effect and treatment efficiency.

[0036] For example, in the initial stage of rubber production, the wastewater contains high concentrations of suspended solids and organic nutrients. At this time, the strongest filtration and adsorption capacity is required to ensure the treatment effect. The operator drives the electric push rod 23 through the control system, so that it moves the sliding part 24 along the strip hole 271 on the reciprocating rod 27 to the position farthest from the rotation center of the reciprocating rod 27.

[0037] According to the lever principle, the lever arm is at its longest at this time, and the vertical swing amplitude of the sliding member 24 reaches its maximum. This makes the up-and-down reciprocating stroke of the floating filter box 15 and the downward filter box 16 reach its maximum value. The longer stroke means that in each upward or downward push, a larger volume of wastewater can be pushed into another filter box, which speeds up the overall circulation speed.

[0038] The longer and faster flow allows for a stronger hydraulic impact as the wastewater passes through the sawdust filler layer 17, which helps overcome blockages caused by high-concentration wastewater and forces the water to penetrate the entire filler layer more evenly, rather than just flowing through the channel of least resistance.

[0039] When the wastewater has undergone preliminary treatment and its concentration has been significantly reduced, excessive filtration intensity is not only unnecessary but also wastes energy. The operator drives the electric push rod 23 to move the sliding part 24 to a position close to the rotation center of the reciprocating rod 27, and the reciprocating stroke of the filter assembly is shortened accordingly.

[0040] Smoother, gentler motion reduces impact and wear on mechanical parts and sawdust filler layer 17, helping to extend the overall lifespan of the equipment.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
