Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to a wastewater treatment device for chemical experiments. Background Technology

[0002] Chemical laboratory wastewater mainly originates from experimental activities in universities, research institutes, and other institutions. During the experiments, a large amount of wastewater is generated. This wastewater has a complex composition, including organic solvents, inorganic solvents, sample stock solutions, various chemicals, mixed liquids, and waste liquids. This wastewater needs to be treated before it can be discharged normally.

[0003] The document with publication number CN119158443A discloses an integrated chemical laboratory wastewater treatment device, belonging to the field of wastewater treatment technology. The following solution is proposed: This invention uses a steerable inlet component to adjust the inlet position, allowing it to correspond to different treatment tanks as needed, satisfying the requirement of automatically switching between different inlet positions. After the steerable inlet component corresponds to the treatment tank, the toothed valve and toothed segment drive each other, automatically opening the drain port of the inlet pipe for direct inlet operation. Simultaneously, through a linkage component and corresponding first gear, it can automatically open the corresponding treatment tank and connect to the three-way valve, facilitating subsequent direct wastewater transport. The steerable inlet pipe can also drive the first motor to automatically switch positions, thus meeting the drive requirements of different positions and reducing operating costs. Through the transmission component and stirring component, the convection component rotates within the treatment tank, achieving vertical convection of wastewater and improving mixing efficiency. However, in actual use, excessive residual elements in the wastewater may cause secondary chemical reactions, thus avoiding unnecessary losses. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a wastewater treatment device for chemical experiments.

[0005] This invention provides a wastewater treatment device for chemical experiments, including a settling tank, the bottom of which is connected to a protective outer shell, and further comprising:

[0006] The settling and impurity removal component is installed inside the settling tank and is used for feeding and settling wastewater.

[0007] Quick-release assembly, used for quick assembly and disassembly of certain parts of the stationary cleaning assembly;

[0008] The curing component is located inside the protective shell. The curing component uses the centrifugal force generated by its own rotation and the negative pressure formed by vacuum adsorption to dehydrate and solidify wastewater and impurities, and is used to clean and separate solid impurities mixed in the wastewater.

[0009] The staff poured the laboratory wastewater and reagents into the settling tank through the inlet hopper, allowing both to stand for a period of time to neutralize the pH value of the wastewater.

[0010] The quick-release assembly allows the filter basket to be quickly assembled and disassembled, making it easy to remove the filter basket.

[0011] The solidification component, the sealing fit between the extrusion disc and the dehydration frame creates an independent, sealed space. Combined with the centrifugal action driven by the drive motor and the vacuum negative pressure dehydration of the pumping mechanism, the dehydration efficiency is significantly improved, effectively separating wastewater and impurities.

[0012] Preferably, the curing component includes:

[0013] The dehydration frame is divided into multiple independent fan-shaped spaces arranged in a circular array, and a water passage groove is opened on the outer periphery of the dehydration frame, and a filter plate is installed in the water passage groove.

[0015] Two symmetrically arranged extrusion discs are slidably connected to a rotating empty tube. A plurality of adsorption extrusion plates arranged in a circumferential array are connected to one side of the extrusion discs. The cross-sectional shape of the adsorption extrusion plates is fan-shaped and the adsorption extrusion plates are adapted to the fan-shaped space within the dehydration frame.

[0016] Rotary slip ring, the rotating slip ring is connected to the outer periphery of the dewatering frame, and the dewatering frame and the rotating slip ring are connected to the dewatering frame;

[0017] A fixed slip ring is rotatably connected to the outer periphery of the rotating slip ring, and the two are connected. The fixed slip ring is fixedly installed inside the protective shell by a fixing post.

[0018] A water pumping mechanism is disposed inside the protective housing, and the water pumping mechanism is connected to the fixed slip ring through a connecting pipe.

[0019] Vibration mechanism, which is set on one side of the extrusion disc, is used to knock off the solidified impurities attached to the adsorption extrusion plate by vibration.

[0020] The drive mechanism is connected to the rotating tube drive and is used to drive the rotation of the rotating tube;

[0021] A fixed disc is connected to the outer surface of the rotating empty tube and is disposed on one side of the extrusion disc;

[0022] Two electric push rods are connected between the fixed disc and the extrusion disc;

[0023] The fan-shaped space of the circumferential array works in conjunction with the water tank and filter plate to achieve rapid dehydration under centrifugal force. At the same time, the filter plate effectively intercepts solid impurities, improving the solid-liquid separation efficiency. Meanwhile, the adsorption extrusion plate is precisely matched with the fan-shaped space, further compressing impurities and discharging residual water during the extrusion process, enhancing the dehydration effect. The fixed disc and the slidingly connected extrusion disc form a stable support, ensuring the accuracy of the extrusion action and reducing vibration and deviation. The water pumping mechanism directly extracts the filtrate through the fixed slip ring, improving the dehydration efficiency.

[0024] Preferably, the vibration mechanism includes:

[0025] Multiple fixed boxes arranged in a circular array are fixedly connected to one side of the extrusion disc;

[0026] A fixing plate is connected to a fixing box, and the fixing plate has sliding holes arranged in a linear array.

[0027] Multiple movable rods are slidably connected in sliding holes. One end of the movable plate is connected to a vibrating block, and the other end of the movable rod is connected to a pressing wheel. A support spring is sleeved on the outer surface of the movable rod, and the two ends of the support spring are respectively connected to one side of the pressing wheel and one side of the fixed plate.

[0028] A lead screw seat, one side of which is in contact with the extrusion wheel, and a plurality of extrusion blocks arranged in a linear array are connected to one side of the lead screw seat. The extrusion blocks can drive the extrusion wheel to move.

[0029] A reciprocating lead screw is connected to a lead screw seat for transmission, and the reciprocating lead screw is rotatably connected inside a fixed box. One end of the reciprocating lead screw extends to the outside of the fixed box and is connected to a drive gear.

[0030] A drive gear ring is connected to one side of a fixed slip ring and meshes with a drive gear.

[0031] The moving rod, under the action of the supporting spring, drives the vibrating block to reciprocate, continuously striking the adsorption and extrusion plate, causing the attached solidified impurities to fall off quickly. The drive gear ring on the fixed slip ring drives the drive gear to rotate, making the reciprocating screw run automatically. No additional power source is required, making it energy-saving and efficient. Multiple fixed boxes are arranged along the circumference of the extrusion disc to ensure that each sector space in the entire dehydration frame can vibrate synchronously, avoiding local blockage.

[0032] Preferably, the drive mechanism includes:

A synchronous belt is used to drive the first synchronous pulley and the second synchronous pulley.

[0035] The first and second synchronous pulleys are connected by a synchronous belt, avoiding the slippage problem of traditional chain or gear transmission. This ensures that the rotation speed of the empty tube and the dehydration frame are strictly matched, improving dehydration stability.

[0042] The lifting linkage mechanism is used to move the lifting box and simultaneously discharge gas;

[0043] The opening and closing mechanism is used to close and close the connecting box.

[0044] Through the linkage design of the lifting box and the airbag, when the lifting box is driven to move up and down by the lifting push rod, the airbag contracts and expands, forcing external gas to be injected into the settling box in one direction through the air inlet pipe. This process creates a bubble stirring effect, which significantly improves the contact efficiency between impurities in the liquid and the filter basket. The synchronous operation of the sliding frame and the partition can realize the connection and isolation between the connecting box and the settling box, and realize the free switching between the sealing and flow of the settling box itself.

[0049] The circularly distributed first and second racks and transmission gears ensure that the airbag is subjected to uniform force, improving the smoothness and stability of air discharge.

[0050] Preferably, the opening and closing mechanism includes:

[0051] Multiple partitions are inserted into the connecting box via through slots, allowing the settling box to switch between closed and open states;

[0052] A square frame, which is connected to a partition and slidably connected to a connecting box;

[0053] The sliding frame is connected to the bottom of the square frame. Multiple sliding grooves are arranged in a circular array on the outer periphery of the static box. The sliding frame is slidably connected in the sliding grooves. The cross-sectional shape of the sliding frame is L-shaped.

[0055] A reset spring is provided, which connects the square frame to the top of the connecting box.

[0056] Multiple sliding sleeves are connected to the outer surface of the settling box, and the sliding frame is slidably connected to the sliding sleeves;

[0057] The partition can slide up and down along the through groove of the connecting box, realizing the rapid closing or opening of the static box, and achieving rapid opening and closing and zero leakage operation of the static box.

[0058] Preferably, the quick-release assembly includes:

[0059] Two clips are attached to both sides of the filter basket, and the two clips are arranged symmetrically.

[0060] The locking block is connected to both sides of the connecting box, and the buckle can engage with the locking block;

[0061] The snap-fit ​​mechanism between the clips and the clips allows for quick assembly and disassembly of the filter basket, significantly improving maintenance efficiency and reducing operational difficulty.

[0062] Preferred options also include:

[0063] The water inlet hopper, whose fixing rod is connected to the top of the settling box, is used to pour in experimental wastewater and reagents;

[0064] The discharge port is located at the bottom of the protective housing and directly below the curing component.

[0065] The discharge port facilitates the removal of solidified impurities, thereby reducing subsequent processes and ensuring processing efficiency.

[0066] Preferred options also include:

[0067] Multiple connecting pipes, which are connected to the bottom of the connecting box;

[0068] A delivery pump, which is connected to the other end of the connecting pipe;

[0069] A delivery pipe is provided at the bottom of the delivery pump, and the other end of the delivery pipe is connected to a rotating empty pipe;

[0070] By connecting the pipe to the delivery pump, wastewater can be collected and treated centrally, improving treatment efficiency.

[0071] Compared with the prior art, the present invention has the following beneficial effects:

[0072] This invention, through the setting of a solidification component, the addition and mixing of flocculants, combined with the setting of a rotating empty pipe and a dewatering frame, allows wastewater to fully contact with the flocculant and form flocculent precipitates. The sealed cooperation between the extrusion disc and the dewatering frame creates an independent and sealed space. Combined with the centrifugal action driven by the drive motor and the vacuum negative pressure dewatering of the pumping mechanism, the dewatering efficiency is significantly improved, effectively separating wastewater from impurities. The filter plate blocks the flocculent precipitates and promotes their solidification and adsorption on the surface of the extrusion plate. The pumping mechanism centrally treats the purified wastewater. After separation and solidification, the electric push rod drives the extrusion disc to disengage, and the drive gear meshes with the gear ring to trigger the reciprocating screw motion. Through the reciprocating vibration of the extrusion block and the vibrating block, the solidified impurities adsorbed on the extrusion plate are efficiently removed and automatically discharged through the discharge hole, avoiding the tedious manual cleaning. This allows the chemical residues in the wastewater to be treated separately after solidification and separation, avoiding secondary reactions of internal chemical elements after subsequent wastewater addition, thereby avoiding unnecessary losses.

[0073] This invention achieves high efficiency and stability in wastewater treatment through an automated mechanical structure by setting up a static sedimentation and impurity removal component. First, the combination of the sedimentation tank and the reagent quickly neutralizes the pH value of the wastewater and promotes the sedimentation of impurities. The mechanical linkage of the lifting push rod, the first rack, the second rack, and the airbag enables the directional spraying of airflow within the lifting tank, effectively agitating the settled impurities and preventing residue. At the same time, the synchronous operation of the sliding frame and the partition enables the connection and isolation between the connecting box and the sedimentation tank, allowing free switching between the sealing and flowability of the sedimentation tank itself, thereby improving the sedimentation effect on wastewater.

[0074] 3. This invention, by setting up a quick-release component, realizes the quick assembly and disassembly of the filter basket through the snap-fit ​​relationship between the buckle and the locking block, which significantly improves maintenance efficiency, reduces the difficulty of operation, and allows the staff to easily remove the filter basket and clean it thoroughly, effectively avoiding the clogging problem caused by long-term use and extending the service life of the equipment.

[0146] As an optional embodiment, it also includes:

[0147] Water inlet 3, the water inlet 3 fixing rod is connected to the top of the settling box 2, for pouring in experimental wastewater and reagents;

[0148] The discharge port 9 is located at the bottom of the protective housing 1 and directly below the curing component 8.

[0149] The discharge port 9 facilitates the discharge of solidified impurities, thereby reducing subsequent processes and ensuring processing efficiency.

[0150] As an optional embodiment, it also includes:

[0151] Multiple connecting pipes 6 are connected to the bottom of the connecting box 401;

[0152] The delivery pump 7 is connected to the other end of the connecting pipe 6;

[0153] The conveying pipe 10 is located at the bottom of the conveying pump 7, and the other end of the conveying pipe 10 is connected to the rotating empty pipe 822.

[0154] By connecting pipe 6 to the transfer pump 7, wastewater can be collected and treated centrally, improving treatment efficiency.

[0155] Working principle of this invention: In use, the operator pours laboratory wastewater into the settling tank 2 through the inlet hopper 3. Then, a reagent is added to the settling tank 2 to neutralize the pH value of the wastewater. The wastewater in the settling tank 2 is allowed to stand for a period of time, allowing some impurities to settle and stabilize. Afterwards, the lifting push rod 408 moves the lifting tank 410 upward. The lifting tank 410 moves the first rack 412 upward. The first rack 412, through the transmission gear 413, moves the second rack 414 downward. The second rack 414 moves the lifting ring 416 downward. The lifting ring 416 causes the airbag 407 to contract. The airbag 407, in conjunction with the air inlet pipe 409, the telescopic hose, and the one-way valve, vents air into the lifting tank 410. Airflow is ejected upward through the exhaust pipe, causing sedimented impurities to float and preventing them from remaining on the top of the lifting box 410. At the same time, the first rack 412 drives the square groove to move. When the square groove moves to a certain position, it drives the sliding frame 406 to move. The sliding frame 406 drives the square frame 402 to move upward. The square frame 402 drives the partition 404 to move upward, so that the partition 404 no longer isolates the connecting box 401 and the settling box 2, allowing the settling wastewater to flow into the connecting box 401. After the wastewater is filtered by the filter basket 415, the impurities can remain in the filter basket 415. The filtered wastewater enters the conveying pump 7 through the connecting pipe 6 and is then conveyed by the conveying pump 7 to the rotating empty pipe 822.

[0156] When the lifting push rod 408 moves the lifting box 410 upward, the operator adds flocculant to the settling box 2 through the water inlet hopper 3. The flocculant, along with the wastewater, is transported into the dewatering frame 812 through the rotating empty pipe 822. At this time, the extrusion disc 813 is in contact with the dewatering frame 812, and the adsorption extrusion plate 814 seals the dewatering frame 812, making the dewatering frame 812 into multiple independent sealed spaces. Then, the drive motor 803 drives the rotating empty pipe 822 to rotate through the transmission system 804. The rotating empty pipe 822 drives the extrusion disc 813 and the dewatering frame 812 to rotate. The water pumping mechanism 801, in conjunction with the connecting pipe 802, can perform vacuum dewatering treatment inside the dewatering frame 812. The wastewater inside is dewatered using the principle of centrifugal force and vacuum negative pressure. Impurities and flocculent precipitates are blocked by the filter plate and retained inside the dewatering frame 812, gradually solidifying and condensing on the surface of the adsorption extrusion plate 814. Wastewater enters the pumping mechanism 801 for storage. After separation and solidification, the electric push rod 811 drives the extrusion disc 813 to move the extrusion plate 814 to both sides and separate it from the dewatering frame 812. At this time, the extrusion disc 813 drives the drive gear 806 to move, enabling the drive gear 806 to mesh with the drive gear ring 810. Rotating the empty tube 822 drives the extrusion disc 813 to rotate, and the extrusion disc 813 drives the drive gear 806 to revolve on the drive gear ring 810. The drive gear ring 810 rotates, which in turn drives the reciprocating screw 818 to rotate. The reciprocating screw 818 drives the screw seat 819 to move back and forth. The screw seat 819 drives the extrusion block 820 to move back and forth. The extrusion block 820, in conjunction with the support spring 821, drives the moving rod 817 to move back and forth. The moving rod 817 drives the vibration block 816 to vibrate one side of the fixed disk 805, causing the solidified impurities remaining on the adsorption extrusion plate 814 to fall off and be discharged through the discharge hole.

[0157] After long-term use, the staff can quickly disassemble and assemble the filter basket 415 by using the snap-fit ​​relationship between the buckle 502 and the clip 501, making it easy to remove the filter basket 415 and clean it to avoid clogging.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.

Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
