Description

Technical Field

[0001] This invention relates to the field of chemical experimental technology, and specifically to a chemical experimental table with chemical solution processing function. Background Technology

[0002] A chemistry lab table is a type of table primarily used in chemistry laboratories, providing a support surface for experiments. The chemical solutions (waste liquids) generated during the experiments mainly include strong acid and alkaline solutions, heavy metal solutions, organic solutions, and biotoxic solutions. Strong acid and alkaline solutions (such as sulfuric acid and sodium hydroxide) can corrode pipes and change the pH value of water bodies if directly discharged. Heavy metal solutions (such as heavy metal solutions containing mercury and lead, and highly toxic reagents such as potassium cyanide and arsenic compounds) are easily bioaccumulated through the food chain. Organic solutions (such as organic solvents such as ethanol and ether) may cause fires when exposed to open flames. Biotoxic solutions (such as culture media containing bacteria and viruses) may spread pathogens. Direct discharge of untreated chemical solutions may lead to water and soil pollution and damage to ecosystems (for example, heavy metal solutions can accumulate in organisms and cause food chain poisoning). Toxic gases volatilized from some solutions (such as cyanide and benzene compounds) can harm the respiratory system of laboratory personnel and surrounding people. Therefore, to avoid environmental pollution and harm to human health caused by chemical solutions, chemical solutions are now collected and professionally treated before being discharged. To facilitate the collection of chemical solutions that need to be treated during experiments, modern chemical lab benches are usually equipped with collection devices for temporary storage of chemical solutions. For example, the Honghan Zanyi chemical lab bench includes a table, drawers, storage cabinets, reagent racks, and solution collection buckets placed under the table. Corrosion-resistant covered buckets are used to collect acidic and alkaline solutions, stainless steel sealed buckets are used to collect organic solutions, special buckets made of polytetrafluoroethylene with double sealing caps are used to collect solutions containing heavy metals, and transparent sealed buckets made of polycarbonate are used to collect biotoxic solutions. By setting up corresponding collection buckets for different types of chemical solutions under the chemical lab bench, it is convenient for experimental personnel to operate. The solutions in the collection buckets are periodically transferred to professional companies for treatment. However, in actual use of the Honghanzanyi Chemical Laboratory Table, the collection of acidic and alkaline solutions is only done through simple collection and temporary storage. During the collection of acidic and alkaline solutions, improper closing of the collection container can easily lead to acid and alkali leakage, causing equipment corrosion or burns to personnel.

[0003] Therefore, this invention proposes a chemical experimental table with chemical solution processing function to solve the above problems. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a chemical laboratory table with chemical solution processing capabilities. By incorporating a structure beneath the chemical laboratory table for preliminary neutralization of chemical solutions, it avoids the leakage risks and high subsequent processing costs associated with traditional laboratory tables that rely solely on collection containers for temporary storage.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A chemical experiment table with chemical solution treatment function includes a table body, a water tank, and a shelf. The water tank and the shelf are arranged sequentially along the length of the table body. A controller is provided on the table body, and the controller is signal-connected to a touch screen embedded in the side wall of the table body. Neutralization chambers are symmetrically arranged on both sides of the water tank in the middle of the table body. pH sensors are provided in the lower middle part of the inner side wall of each neutralization chamber, and the pH sensors are signal-connected to the controller. The neutralization chambers are located away from the water tank. Each side is fixedly connected to a fixing block. Both sides of the inner wall of the table have vibration grooves corresponding to the fixing blocks. The fixing blocks are slidably engaged with the corresponding vibration grooves. A neutralization tube is slidably engaged in the middle of the neutralization cavity. The neutralization tube is connected to the neutralization cavity. The top of the neutralization tube extends through the top wall of the corresponding neutralization cavity and the top wall of the table to the top of the table. The neutralization tube is fixedly connected to the table. Several through holes are opened on the part of the neutralization tube located in the neutralization cavity. A waste liquid pipe is connected to the top of the neutralization cavity near the water tank. The top of the waste liquid pipe extends through the top wall of the table to the top of the table. The bottom of each neutralization chamber is connected to a T-connector. At the other two ends of the T-connector, there are collection components for collecting waste liquid after neutralization and wastewater components for collecting wastewater generated during cleaning of the neutralization chamber. The vibration tank is equipped with auxiliary components for controlling the vibration of the neutralization chamber to make the neutralization reaction more complete.

[0006] The technical principle of the above scheme is as follows: When acidic or alkaline waste liquid is generated during the experiment, it is poured into the corresponding neutralization chamber through the corresponding waste liquid pipe. Then, the corresponding neutralizing agent is introduced from the top of the neutralization pipe. After entering the neutralization pipe, the neutralizing agent is released into the neutralization chamber through the through hole and mixes with the waste liquid. The controller controls the auxiliary component to drive the neutralization chamber to vibrate up and down along the height direction of the vibration tank, so that the neutralizing agent and the waste liquid are fully mixed and the neutralization reaction is accelerated. At the same time, the pH sensor on the neutralization chamber monitors the pH value of the solution in real time and feeds back the pH value data signal to the controller. When the pH value reaches neutral (preset threshold), the neutralized waste liquid is temporarily stored through the collection component. After the waste liquid is collected, clean water is injected into the neutralization chamber through the neutralization pipe. When the clean water flows through the through hole, it forms a jet along the circumference of the central pipe. With the help of the auxiliary component, the neutralization chamber is vibrated, which efficiently cleans the neutralization chamber. The wastewater used to clean the neutralization chamber is collected through the wastewater component.

[0007] The above approach has the following beneficial effects: 1. This solution uses a neutralization chamber to centrally treat acidic and alkaline solutions, avoiding acid and alkali leakage caused by improper closure of traditional collection tanks, and reducing the risk of equipment corrosion and personnel burns. 2. In this scheme, the neutralization reaction is carried out in a closed neutralization chamber, which reduces the possibility of toxic gases being generated by chemical reactions during the temporary storage of waste liquid. 3. This solution reduces the cost and difficulty of subsequent professional processing by performing preliminary neutralization treatment during the experiment.

[0008] Furthermore, each collection component includes a collection pipe, which is connected to one end of a corresponding tee pipe. The bottom end of each collection pipe is connected to a collection bucket, which is detachably connected to the bottom wall of the table. A collection valve is provided at the connection between the collection pipe and the tee pipe, and the collection valve is connected to the controller signal.

[0009] Beneficial effects: After the neutralization reaction is completed, the controller transmits the neutralization result to the touch screen display based on the pH value signal. The controller then opens the collection valve, allowing the waste liquid to enter the collection tank through the collection pipe for collection of the neutralized waste liquid.

[0010] Furthermore, each sewage component includes a sewage pipe, which is connected to the other end of a corresponding tee pipe. The bottom end of each sewage pipe is connected to a sewage tank, which is detachably connected to the bottom wall of the table. Each sewage pipe and tee pipe is equipped with a sewage valve, which is connected to the controller signal.

[0011] Beneficial effects: After the neutralized waste liquid is collected, the neutralization chamber is cleaned. After cleaning, the sewage valve is opened by the controller to discharge the sewage from the neutralization chamber into the sewage chamber. After the sewage is completely discharged, the sewage valve is closed.

[0012] Furthermore, the auxiliary components all include electric cylinders, which are all connected to the controller signal, are all fixedly connected to the bottom wall of the corresponding vibration groove, and the output end of the electric cylinders is fixedly connected to the corresponding fixed block.

[0013] Beneficial effects: By controlling the operation of the electric cylinder through the controller, the output shaft of the electric cylinder drives the fixed block to move up and down reciprocally, thereby causing the neutralization chamber to vibrate up and down, so that the neutralizing agent and waste liquid are mixed more evenly and the reaction is more thorough, which can improve the utilization rate of the neutralizing agent.

[0014] Furthermore, the top wall of the table body is fixedly connected to several pneumatic chambers corresponding to the neutralization chamber. The side walls of the pneumatic chambers are all fixedly connected to the corresponding inner side walls of the table body. The pneumatic chambers are all slidably fitted with piston plates arranged horizontally along the top of the table body. The bottom of the piston plates is fixedly connected to a fixing rod. The bottom end of the fixing rod passes through the bottom wall of the pneumatic chamber and extends to the bottom of the pneumatic chamber and is fixedly connected to the top of the corresponding neutralization chamber. The pneumatic chambers are all connected to the corresponding neutralization pipes. The bottom wall of the pneumatic chambers is opened with a pressure relief port, and a pressure relief valve is provided at the pressure relief port.

[0015] Beneficial effects: When the neutralization chamber vibrates up and down, it drives the fixed rod and piston plate to slide up and down in the pneumatic chamber. When the piston plate moves upward, the pressure in the pneumatic chamber increases, and air is forced into the neutralization tube. The air enters the neutralization chamber through the through hole on the neutralization tube, forming bubbles, which stir the waste liquid. The vibration is made more complete by the stirring of the bubbles.

[0016] Furthermore, buffer pads are fixedly connected to the top wall of the vibration groove.

[0017] Beneficial effects: The buffer pad absorbs the impact force of the fixed block hitting the top wall of the vibration groove, avoiding damage to the vibration groove and fixed block caused by long-term vibration and impact.

[0018] Furthermore, a one-way valve is installed at the connection between the pneumatic cavity and the neutralization pipe.

[0019] Beneficial effect: The one-way valve ensures that air can only flow from the pneumatic chamber to the neutralization pipe, preventing the waste liquid in the neutralization pipe from flowing back and causing damage to the internal components of the pneumatic chamber.

[0020] Furthermore, both the top of the neutralization tube and the top of the waste liquid tube are detachably connected with tube caps.

[0021] Beneficial effects: When treating waste liquid, open the caps at the top of both the neutralization tube and the waste liquid tube, pour the waste liquid and neutralizing agent into the corresponding pipes, and then close the caps to carry out the neutralization reaction; when the solution treatment is finished or when not in use, close the caps to form a physical barrier to prevent foreign objects (such as experimental equipment, dust, etc.) from entering the pipes and causing blockage or pollution.

[0022] Furthermore, the neutralization pipe, waste liquid pipe, neutralization chamber, sewage pipe, collection pipe, sewage tank, and collection tank are all made of corrosion-resistant materials.

[0023] Beneficial effects: The design using corrosion-resistant materials improves the equipment's corrosion resistance, preventing the risk of waste liquid leakage caused by corrosion damage.

[0024] Furthermore, the bottom walls of the neutralization chamber are all designed with a conical structure.

[0025] Beneficial effects: The conical structure design at the bottom of the neutralization chamber, combined with the force of the liquid's own weight, reduces the residue of waste liquid after neutralization and cleaning wastewater, thus improving the emptying effect of the neutralization chamber.

[0031] The following detailed description illustrates the specific implementation method: Example 1:

[0032] As attached Figure 1As shown: A chemical experiment table with chemical solution treatment function includes a table body 1, a water tank 2, and a shelf. The water tank 2 and the shelf are arranged sequentially along the length of the table body 1. Chemical solutions (waste liquids) generated during the experiment are temporarily stored in independently set collection containers. Organic waste liquids, waste liquids containing heavy metals, and biotoxic waste liquids are temporarily stored in sealed special collection containers, while acidic and alkaline waste liquids are temporarily stored in simple corrosion-resistant containers. During the collection of acid / alkaline waste liquids, improper closure of the collection containers can easily lead to acid / alkali leakage, causing equipment corrosion or burns to personnel. To improve the safety of collecting acid and alkali waste liquids, as shown in the attached document... Figure 2 As shown, a controller is installed on the table body 1, preferably a Siemens SIMATIC S7-1200. The controller is connected to a touch screen embedded in the side wall of the table body 1, preferably a Siemens SIMATIC HMI KTP700 Basic. Neutralization chambers 3 are symmetrically located on both sides of the water tank 2 in the center of the table body 1. The bottom walls of the neutralization chambers 3 are all designed with a conical structure (the conical structure, combined with the gravity of the liquid, helps to improve the emptying effect of the neutralization chambers 3). Combined with the attached... Figure 2 The left side is designated as a neutralization chamber 3 for acidic solution (waste liquid), and the right side is designated as a neutralization chamber 3 for alkaline solution (waste liquid). A pH sensor is installed on the lower middle part of the inner wall of each neutralization chamber 3. The pH sensors are preferably Mettler Toledo InPro 4800 models and are connected to the controller signal. A fixing block 4 is integrally formed on the side of each neutralization chamber 3 away from the water tank 2. Vibration grooves 5 corresponding to the fixing blocks 4 are formed on both sides of the inner wall of the table body 1. The fixing blocks 4 slide with the corresponding vibration grooves 5 via sliding grooves and rails. A buffer pad 20 is adhered to the top wall of each vibration groove 5 (the buffer pad 20 absorbs the impact force of the fixing blocks 4 hitting the top wall of the vibration groove 5 when sliding within it, reducing wear on the fixing blocks 4). A neutralization tube 6 slides in the middle of each neutralization chamber 3, communicating with the neutralization chamber 3. The top of the neutralization tube 6 extends through the top wall of the corresponding neutralization chamber 3 and the top wall of the table body 1 to the top of the table body 1. All parts passing through the table body 1 are bonded to the table body 1. The part of the neutralization tube 6 located inside the neutralization cavity 3 has several through holes 7 (the through holes 7 are always inside the neutralization cavity 3 during the relative sliding process between the neutralization cavity 3 and the neutralization tube 6). The top of the neutralization cavity 3 is connected to the waste liquid tube 8 near the water tank 2 (the connection between the waste liquid tube 8 and the corresponding neutralization cavity 3 uses a flexible joint, such as a rubber hose or corrugated pipe, to absorb the displacement and vibration force generated by the vibration of the neutralization cavity 3). The top of the waste liquid tube 8 extends through the top wall of the table body 1 to the top of the table body 1. The top of the neutralization tube 6 and the top of the waste liquid tube 8 can be detachably connected to a tube cap (to prevent foreign objects from entering and causing blockage when no solution treatment is performed). The bottom of each neutralization chamber 3 is connected to a three-way pipe 9. Each end of the three-way pipe 9 is equipped with a collection component for collecting waste liquid after neutralization and a wastewater collection component for collecting wastewater generated during cleaning of the neutralization chamber 3. The vibration tank 5 is equipped with auxiliary components for controlling the vibration of the neutralization chamber 3 to ensure a more complete neutralization reaction; as shown in the attached diagram. Figure 2 and attached Figure 3 As shown, each collection component includes a collection pipe 10, which is connected to one end of a corresponding tee pipe 9 (the connection between the collection pipe 10 and the corresponding tee pipe 9 uses a flexible joint, such as a rubber hose or corrugated pipe). The bottom end of each collection pipe 10 is connected to a collection bucket 11, which is detachably connected to the inner bottom wall of the table body 1. A collection valve 12 is provided at the connection between the collection pipe 10 and the tee pipe 9. The preferred model of the collection valve 12 is a Burkert Type 6013 solenoid valve, and the collection valve 12 is connected to the controller signal. Each wastewater component includes a wastewater pipe 13, which is connected to the other end of a corresponding tee pipe 9 (the connection between the wastewater pipe 13 and the corresponding tee pipe 9 uses a flexible joint). The bottom end of each wastewater pipe 13 is connected to a wastewater bucket 14, which is detachably connected to the inner bottom wall of the table body 1. A wastewater valve 15 is provided at the connection between the wastewater pipe 13 and the tee pipe 9. The preferred model of the wastewater valve 15 is a Burkert Type 6013 solenoid valve. Both the solenoid valve and the sewage valve 15 are connected to the controller signal. As attached Figure 3 As shown, all auxiliary components include an electric cylinder 16, preferably an SMC standard electric cylinder. Each electric cylinder 16 is connected to the controller signal and is bolted to the bottom wall of the corresponding vibration groove 5. The output end of each electric cylinder 16 is bolted to the corresponding fixing block 4. To further accelerate the neutralization reaction within the neutralization chamber 3, as shown in the attached diagram... Figure 2 and attached Figure 3 As shown, several pneumatic chambers 17 corresponding to the neutralization chambers 3 are welded to the inner top wall of the table body 1. The side walls of the pneumatic chambers 17 are all welded to the corresponding inner side walls of the table body 1. Piston plates 18 are slidably fitted inside the pneumatic chambers 17 and are arranged horizontally along the top of the table body 1. The bottom of the piston plates 18 are all fixedly connected to the fixing rods 19 by bolts. The bottom ends of the fixing rods 19 extend through the bottom wall of the pneumatic chambers 17 to the bottom of the pneumatic chambers 17 and are fixedly connected to the top of the corresponding neutralization chambers 3 by bolts. The pneumatic chambers 17 are all connected to the corresponding neutralization pipes 6. A one-way valve 21 is provided at the connection between the pneumatic chambers 17 and the neutralization pipes 6 (to ensure that air can only flow from the pneumatic chambers 17 to the neutralization pipes 6 and to prevent waste liquid from flowing back). The bottom wall of the pneumatic chambers 17 is opened with a pressure relief port, and a pressure relief valve is provided at the pressure relief port.

[0033] The specific implementation process is as follows: After completing a chemical experiment, the experimenter generated acidic waste liquid. At this time, it is necessary to use alkaline neutralizing solution (such as sodium hydroxide solution) to neutralize the acidic waste liquid to avoid the harm caused by direct discharge. The experimenter first selects the neutralization chamber 3 on the left side of the water tank 2 according to the type of waste liquid (acidic). Then, the experimenter opens the cap at the top of the waste liquid pipe 8 on the left side and pours the acidic waste liquid into the neutralization chamber 3 on the left side through the waste liquid pipe 8. After pouring, the cap of the waste liquid pipe 8 is closed to prevent foreign objects from entering and the waste liquid from evaporating. Next, the experimenter opens the cap at the top of the neutralization pipe 6 on the left side and pours the alkaline neutralizing solution from the top of the neutralization pipe 6. After the neutralizing solution enters the neutralization pipe 6, it is evenly released into the neutralization chamber 3 through the through holes 7 located inside the neutralization chamber 3 of the neutralization pipe 6, and is initially mixed with the waste liquid. The cap of the neutralization pipe 6 is then closed to prevent foreign objects from entering the neutralization pipe 6 and causing blockage of the neutralization pipe 6 and the through holes 7. At this time, the experimenter sends a vibration start command to the controller via the touch screen. After receiving the command, the controller starts the electric cylinder 16. The output end of the electric cylinder 16 drives the fixed block 4 to slide upward along the height direction of the vibration groove 5. The fixed block 4 drives the neutralization chamber 3 and the three-way pipe 9 to slide upward synchronously. Then, the output end of the electric cylinder 16 pulls the fixed block 4 downward, driving the neutralization chamber 3 to move downward synchronously. This process is repeated to make the neutralization chamber 3 vibrate up and down, so that the neutralizing agent and waste liquid in the neutralization chamber 3 can be fully mixed, accelerating the neutralization reaction. During the vibration of the neutralization chamber 3, the flexible joint absorbs the vibration displacement and vibration force of the neutralization chamber 3, avoiding collisions and damage between the neutralization chamber 3 and the waste liquid pipe 8, and between the three-way pipe 9 and the collection pipe 10 and the sewage pipe 13. During the vibration of the neutralization chamber 3, the piston plate 18 is driven by the fixed rod 19 to slide up and down in the pneumatic chamber 17. When the neutralization chamber 3 moves upward, the fixed rod 19 and piston plate 18 slide upward synchronously, the upper volume of the pneumatic chamber 17 decreases to form positive pressure, and the air inside the pneumatic chamber 17 is forced into the neutralization tube 6 through the one-way valve 21. At this time, the cap at the top of the neutralization tube 6 is in a closed state. The air is pressurized and enters the neutralization chamber 3 through the through hole 7 on the neutralization tube 6, further agitating the liquid inside the neutralization chamber 3. If the through hole 7 is located below the liquid surface inside the neutralization chamber 3, the gas will form bubbles through the through hole 7 to further agitate the liquid inside the neutralization chamber 3 and promote the full mixing of the neutralizing agent and the waste liquid. When the neutralization chamber 3 moves downward, the piston plate 18 slides down, the upper volume of the pneumatic chamber 17 increases to form negative pressure, and the one-way valve 21 closes. The electric control cylinder 16 drives the neutralization chamber 3 to vibrate, which, together with the air pressure change of the pneumatic chamber 17, agitates the liquid inside the neutralization chamber 3, making the neutralizing agent and the waste liquid mix more evenly and the neutralization reaction more complete. During the neutralization reaction, the pH value of the solution is monitored in real time by a pH sensor, and the pH value data signal is continuously fed back to the controller. The controller compares the real-time pH value with the preset neutral threshold (usually 6.5-7.5). When the pH value reaches the neutral threshold, the controller automatically controls the electric cylinder 16 to stop working, and the neutralization reaction is completed. The setting of the pH sensor enables precise control of the neutralization reaction, avoiding waste of neutralizing agent or incomplete neutralization. After the neutralization reaction is completed, a command to open the collection valve 12 is sent to the controller via the touch screen. The collection valve 12 is opened, and the neutralized waste liquid flows into the collection pipe 10 through the three-way pipe 9 connected to the bottom of the neutralization chamber 3 under its own gravity and in conjunction with the conical structure of the bottom wall of the neutralization chamber 3. Finally, it enters the collection bucket 11 connected to the bottom end of the collection pipe 10 for temporary storage. The collection bucket 11 is detachably connected to the bottom wall of the table body 1 for convenient periodic removal and transportation. After the waste liquid from the neutralization reaction is collected, the collection valve 12 is closed. The experimenter then opens the cap at the top of the neutralization tube 6 again and injects clean water into the neutralization tube 6. The clean water enters the neutralization chamber 3 through the through hole 7 on the neutralization tube 6. When the clean water flows through the through hole 7, it forms a jet along the circumference of the neutralization tube 6. At the same time, the experimenter restarts the electric control cylinder 16 through the touch screen, causing the neutralization chamber 3 to continue vibrating. The combined effect of the jet and vibration effectively cleans the waste liquid residue on the inner wall of the neutralization chamber 3, avoiding cross-contamination during subsequent neutralization treatment. The wastewater generated during the cleaning process is sent to the controller by the experimenter through the touch screen. The controller controls the wastewater valve 15 in the wastewater component to open. The wastewater flows into the wastewater pipe 13 through the three-way pipe 9 and finally enters the wastewater tank 14 for collection. The wastewater tank 14 also adopts a detachable connection method for easy subsequent treatment.

[0034] Example 2:

[0035] As attached Figure 2 As shown, the difference from Example 1 is that the neutralization pipe 6, waste liquid pipe 8, neutralization chamber 3, sewage pipe 13, collection pipe 10, sewage tank 14 and collection tank 11 are all made of corrosion-resistant materials; the design of corrosion-resistant materials improves the corrosion resistance of the equipment and avoids the risk of waste liquid leakage caused by corrosion damage to the equipment.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
