Description

Technical Field

[0001] This invention relates to the field of chemical filling, and in particular to an integrated device for chemical filling, supply and recycling. Background Technology

[0002] Chemical filling is an industrial unit operation that quantitatively, securely, and safely fills liquid chemical products into packaging containers according to a set weight or volume. Signals are collected through weighing sensors, flow meters, piston stroke, etc., and the opening and closing of the feed valve are controlled in a closed loop to achieve fixed weight or fixed volume filling, ensuring that the weight or volume of each container meets the standard. Liquid transportation is achieved by gravity, pressure difference, or diaphragm pumps. The transportation method is selected according to viscosity, corrosiveness, and solid content to prevent leakage and material corrosion.

[0003] During the chemical liquid filling process, a float-type surface skimmer is placed inside the chemical drum to remove foam from the liquid surface. After filling, the conventional method for cleaning the residual liquid on the float-type surface skimmer is gravity drainage. This involves verticalizing or slightly tilting the structure, allowing gravity to return the liquid on the float or skimmer arm back into the chemical drum. However, this conventional cleaning and recovery method has the following drawbacks: (1) Due to the impact of the liquid at the filling port, the scraper arm of the scraper structure will come into contact with the liquid. Therefore, after the structure finishes its work, some liquid will remain on the scraper arm. It is difficult to recover all the residual liquid on the scraper arm into the chemical drum by gravity drainage. When changing the chemical drum for filling, the liquid on the scraper arm is easy to drip onto the transport platform, which will cause pollution. In addition, gravity drainage requires time to stand, which reduces filling efficiency.

[0004] (2) The function of the float-type liquid surface scraper structure is to scrape off foam. During the foam bursting process, tiny droplets will be generated, forming a thin layer of liquid on the scraper arm. The tiny droplets adhering to the scraper arm are difficult to be recovered into the chemical drum by gravity. During the process of changing the chemical drum, they come into contact with air, which can easily cause the liquid on the scraper arm to be contaminated. After entering the next chemical drum, the contaminated liquid will cause the chemical liquid in the new chemical drum to be contaminated. Summary of the Invention

[0005] This invention provides an integrated device for chemical filling, supply and recycling, which can solve the problem that it is difficult to recycle the liquid on the skimmer structure after the chemical liquid has been filled by gravity dripping.

[0006] One of the objectives of this invention is achieved through the following technical solution: This application provides an integrated chemical filling, supply and recycling device, including a filling machine, a conveyor platform and filling barrels placed on the conveyor platform. The filling machine includes a body, a liquid supply component, a moving component, a sealing cap, a foam scraping component, a gas recovery component and a liquid recovery component. The liquid supply assembly includes a liquid supply system and a filling port. The sealing cap is provided with a liquid inlet, and the filling port fills the filling barrel with liquid through the liquid inlet. The liquid recovery assembly includes a gripping component and an absorbent pad. The absorbent pad is fixedly installed at the bottom of the sealing cover. The gripping component drives the skimmer assembly to move upward. The gas recovery assembly blows away the liquid on the skimmer assembly, while the absorbent pad recovers the residual liquid on the skimmer assembly.

[0007] A further aspect of the present invention is that: the moving component includes a linear slide, an mounting plate is provided on one side of the machine body, a positioning plate is fixedly mounted on one side of the mounting plate, a positioning slide is fixedly mounted on the filling port, the positioning slide is slidably mounted on the positioning plate, the linear slide is fixedly mounted on the mounting plate, and the mounting plate is slidably disposed on the linear slide via a slide cylinder, thereby driving the filling port to move up and down.

[0008] A further aspect of the present invention is that: the skimming assembly includes a suspended ball, and multiple scrapers are installed on the outside of the suspended ball. When the suspended ball is located in the liquid inside the filling tank, the bottom of the scraper is level with the liquid surface, and the scraper is in an inclined state so that when the liquid in the filling port is being filled, the liquid impacts the scraper, thereby driving the multiple scrapers to rotate.

[0009] A further aspect of the present invention is that: a plurality of hinge seats are fixedly installed around the circumference of the suspended ball, a movable plate is hingedly installed on the hinge seat, the scraper is rotatably connected to the movable plate through a bearing, and torsion springs are installed at the connection points between the movable plate and the scraper, and between the movable plate and the hinge seat.

[0010] A further aspect of the present invention is that the gas recovery assembly includes an inlet pipe, which is installed on a sealing cap and communicates with a filling barrel, and the inlet pipe introduces inert gas into the filling barrel.

[0011] A further aspect of the present invention is that the gas recovery assembly further includes a gas outlet pipe, which is installed on the sealing cap and communicates with the filling tank. The gas outlet pipe recovers the gas generated during the liquid filling process and the gas generated when the foam removal assembly removes foam.

[0012] A further aspect of the present invention is that: the absorbent pad is provided with a plurality of inclined grooves, and when the gripping member drives the shaving assembly to move upward, it drives the scraper to move into the inclined grooves.

[0013] A further aspect of the present invention is that: a mounting platform is fixedly connected to the top of the sealing cover, a servo cylinder is fixedly connected to the mounting platform, the output end of the servo cylinder is fixedly connected to the gripping component, and the mounting platform is fixedly connected to the positioning slide via a connecting plate.

[0014] A further aspect of the present invention is that the gripping component includes a pneumatic gripper, and a conical locking block is rotatably connected to the top of the suspended ball, wherein the pneumatic gripper grips and fixes the suspended ball through the conical locking block.

[0015] A further aspect of the present invention is that a funnel sleeve is fixedly installed on the sealing cap, the funnel sleeve passes through the sealing cap and the water-absorbing pad, and the liquid outlet end of the filling port is sleeved inside the funnel sleeve.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This application eliminates foam by injecting inert gas into the filling barrel and removes the liquid suspended on the foam scraper assembly. After the liquid in the filling tank is filled, the gripper moves the scraper assembly upward. During this movement, the gas delivered by the air inlet pipe impacts the scraper. Because the scraper is tilted, the gas impacts the scraper, causing the scraper assembly to rotate, generating centrifugal force. This causes the liquid on the scraper surface to move outward. Simultaneously, through the rotatable connection between the scraper and the movable plate, the hinge between the movable plate and the suspended ball, and the torsion springs installed in all three, the gas in the air inlet pipe impacts the scraper, causing it to rotate downward while deflecting. When the scraper leaves the impact zone of the air inlet pipe, the torsion springs reset the scraper, causing it to vibrate and quickly remove the liquid from the scraper surface. This removes the liquid hanging on the scraper surface. Furthermore, the absorbent pad allows the scraper to absorb any tiny droplets adhering to it, thus recovering the liquid on the scraper. This solves the problem of difficulty in recovering liquid from the scraper structure after chemical liquid filling using gravity draining.

[0017] (2) This application eliminates the gases generated during the filling process and the tiny water mist suspended in the air when the foam-scraping component breaks the foam by introducing inert gas into the filling tank. When liquid is introduced into the filling tank from the filling port, foam and gases generated by the chemical reaction are produced. When the foam is eliminated by the foam-scraping component, water mist is generated at the moment the foam breaks and is suspended inside the filling tank. By introducing inert gas into the filling tank, the air inside the filling tank is compressed, and the gases and water mist generated inside the filling tank are discharged from the gas outlet and recycled, preventing the gas from escaping and causing pollution to the environment.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1 to 5 As shown, an embodiment of the present invention provides a chemical filling, supply and recycling integrated device, including a filling machine 1, a conveyor 2 and a filling barrel 3 placed on the conveyor 2. The filling machine 1 includes a body 100, a liquid supply component 200, a moving component 300, a sealing cap 400, a foam scraping component 500, a gas recovery component 600 and a liquid recovery component 700. The liquid supply assembly 200 includes a liquid supply system 201 and a filling port 202. The sealing cap 400 is provided with a liquid inlet 203, and the filling port 202 fills the filling tank 3 with liquid through the liquid inlet 203. The liquid recovery assembly 700 includes a gripping member 701 and a water-absorbing pad 702. The water-absorbing pad 702 is fixedly installed at the bottom of the sealing cover 400. The gripping member 701 drives the skimmer assembly 500 to move upward. The gas recovery assembly 600 blows away the liquid on the skimmer assembly 500, and at the same time, the water-absorbing pad 702 recovers the residual liquid on the skimmer assembly 500.

[0021] The working principle of the above-mentioned integrated chemical filling, supply, and recovery device is as follows: The filling barrel 3 is transported to the bottom of the liquid supply component 200 via the transport platform 2. The moving component 300 moves the sealing cap 400 and the filling port 202 downwards, causing the sealing cap 400 to seal the top of the filling barrel 3. Then, the liquid supply system 201 introduces chemical liquid into the filling barrel 3 through the filling port 202. Simultaneously, the gripping component 701 releases the foam scraper component 500, allowing the foam scraper component 500 to enter the bottom of the filling barrel 3. The foam scraper component 500 removes the foam generated during liquid filling. At the same time, inert gas is introduced into the filling barrel 3 through the gas recovery component 600. Inert gas is used to remove and recover the gas generated during the filling process in the filling barrel 3, as well as the tiny water mist suspended in the air generated when the foam scraper assembly 500 breaks the foam. After the liquid in the filling barrel 3 is filled, the gripper 701 fixes the foam scraper assembly 500, the gas recovery assembly 600 blows off the liquid on the foam scraper assembly 500, and the water absorption pad 702 recovers the tiny droplets on the foam scraper assembly 500. Finally, the moving assembly 300 drives the sealing cap 400 and the filling port 202 to reset, and the next batch of filling barrels 3 is transported to the bottom of the liquid supply assembly 200 for the next round of filling via the transport platform 2.

[0022] In traditional filling processes, liquid suspended on the scraper arm of the foam-scraping assembly is removed by gravity draining. However, gravity draining requires a settling time, which reduces filling efficiency. Furthermore, as foam breaks down, tiny droplets adhere to the scraper arm, making it difficult to collect these droplets back into the chemical container by gravity. In contrast, this application removes the liquid suspended on the foam-scraping assembly 500 simultaneously by injecting inert gas into the filling container 3 to eliminate foam. After the liquid in the filling tank 3 is filled, the gripper 701 drives the scraper assembly 500 to move upward. During the movement, the gas delivered by the air inlet pipe 601 impacts the scraper 502. Since the scraper 502 is inclined, when the gas impacts the scraper 502, it drives the scraper assembly 500 to rotate, thereby generating centrifugal force, which in turn drives the liquid on the surface of the scraper 502 to move outward. At the same time, through the rotatable connection between the scraper 502 and the movable plate 504, the hinge between the movable plate 504 and the suspended ball 501, and the torsion springs installed in all three, when the gas in the air inlet pipe 601 impacts the scraper 502, it drives the scraper 502 to rotate. While rotating in the 02 direction, it also rotates downwards. After the scraper 502 disengages from the impact zone of the air intake pipe 601, the torsion spring causes the scraper 502 to reset, thereby causing the scraper 502 to vibrate. This causes the liquid to quickly detach from the scraper 502, thus removing the liquid suspended on the surface of the scraper 502. At the same time, the absorbent pad 702 allows the scraper 502 to absorb the tiny droplets adhering to it after entering the absorbent pad 702, thereby recovering the liquid on the scraper 502. This solves the problem that it is difficult to recover the liquid on the scraper structure by gravity drainage after the chemical liquid is filled.

[0023] See also Figures 6 to 7 As shown, in order to recover the water mist suspended in the filling tank 3 when the foam bursts, the gas recovery assembly 600 includes an air inlet pipe 601, which is installed on the sealing cover 400 and communicates with the filling tank 3. The air inlet pipe 601 introduces inert gas into the filling tank 3. The gas recovery assembly 600 also includes an air outlet pipe 602, which is installed on the sealing cover 400 and communicates with the filling tank 3. The air outlet pipe 602 recovers the gas generated during the liquid filling process and the gas generated when the foam scraper assembly 500 removes foam. During the process of removing foam from the surface of the chemical liquid inside the filling tank 3, the foam breaks down, generating water mist that is suspended inside the tank. At the same time, the chemical liquid generates related gases during the filling process. Inert gas is introduced into the filling tank 3 through the air inlet pipe 601. Since the opening of the filling tank 3 is sealed by the sealing cap 400, the inert gas continuously occupies the gas phase space inside the tank. The total gas phase volume is limited. The newly added inert gas pushes the original gas and water mist outward from the air outlet pipe 602. At the same time, a small portion of the water mist is pushed to the liquid surface, causing the water mist to dissolve on the liquid and the foam removal component 500. As the filling liquid continues to rise, it further occupies the gas phase space, accelerating the replacement and discharge of gas and the recovery of water mist in the filling tank 3. This process recovers the gases generated during the liquid filling process and the gases generated when the foam removal component 500 removes foam.

[0024] See also Figures 9 to 11 as well as Figure 4 and Figure 5 As shown, in order to quickly remove and recover the liquid suspended on the scraper 502, the skimmer assembly 500 includes a suspension ball 501. Multiple scrapers 502 are installed outside the suspension ball 501. When the suspension ball 501 is in the liquid in the filling tank 3, the bottom of the scraper 502 is level with the liquid surface and the scraper 502 is in an inclined state so that when the liquid in the filling port 202 is filled, the liquid impacts the scraper 502, thereby driving the multiple scrapers 502 to rotate. Multiple hinge seats 503 are fixedly installed around the suspension ball 501. A movable plate 504 is hingedly installed on the hinge seat 503. The scraper 502 is rotatably connected to the movable plate 504 through bearings. Torsion springs are installed at the connection between the movable plate 504 and the scraper 502, as well as between the movable plate 504 and the hinge seat 503. The suspended ball 501 is fixed by the gripper 701. Due to the inclined installation of the scraper 502, when inert gas is introduced into the filling tank 3 through the air inlet pipe 601, the gas impacts the scraper 502, causing the scraper 502 and the suspended ball 501 to rotate. The centrifugal force generated by the rotation of the suspended ball 501 and the scraper 502 accelerates the dripping speed of residual liquid on the scraper 502. At the same time, the hinge between the movable plate 504 and the suspended ball 501 causes the scraper 502 to rotate downward when the gas impacts it. This causes the end of the scraper 502 near the inner wall of the filling tank 3 to face downward, forming an inclined slope. When the gas flows downward along the inclined slope of the scraper 502, it blows the liquid on the scraper 502 downward. This further accelerates the flow rate of the liquid on the scraper 502. Simultaneously, the torsion springs installed at the connections between the movable plate 504 and the scraper 502, and between the movable plate 504 and the hinge plate, cause the scraper 502 to rotate downwards while its horizontal tilt angle is greater when the gas blows towards it. When the scraper 502 leaves the blowing area of ​​the air inlet pipe 601, the elastic force provided by the torsion spring causes the scraper 502 to rotate upwards and reset, simultaneously rotating upwards horizontally. This causes the scraper 502 to vibrate during its entry and exit from the blowing area, further accelerating the speed at which the dripping liquid on the scraper 502 detaches from it, thereby cleaning the flowable liquid on the scraper 502 and recovering it into the filling tank 3.

[0025] See also Figures 9 to 10 As shown, in order to remove and recycle the tiny droplets generated by foam breakage on the scraper 502, the absorbent pad 702 is provided with multiple inclined grooves 703. When the gripper 701 moves the foam scraping assembly 500 upward, it moves the scraper 502 into the inclined grooves 703. The absorbent pad 702 is made of polytetrafluoroethylene (PTFE). PTFE absorbent pad 702 has high temperature resistance, corrosion resistance, and extremely strong chemical stability, reacting almost no with any chemicals. Its microporous structure can absorb liquid without dissolving or expanding. After the liquid on the surface of the scraper 502 has been cleaned and recovered, tiny water droplets generated when the foam breaks remain on its surface. These tiny droplets adhering to the scraper arm are difficult to recover into the chemical drum by gravity. The gripping component 701 continuously drives the scraper assembly 500 upward, causing the scraper 502 to enter the inclined groove 703 on the absorbent pad 702. The absorbent pad 702 cleans the tiny water droplets on the surface of the scraper 502, thereby further recovering the liquid on the surface of the scraper 502.

[0026] See also Figures 6 to 7 and Figure 11As shown, in order to seal the filling barrel 3 and grasp the suspended ball 501 after filling, the moving component 300 includes a linear slide 301, a mounting plate 302 is provided on one side of the machine body 100, a positioning plate 303 is fixedly installed on one side of the mounting plate 302, a positioning slide 304 is fixedly installed on the filling port 202, the positioning slide 304 is slidably installed on the positioning plate 303, the linear slide 301 is fixedly installed on the mounting plate 302, and the mounting plate 302 is slidably placed on the linear slide 301 by a slide cylinder, which drives the filling port 202 to move up and down; the top of the sealing cover 400 is fixedly connected to the mounting platform 40 1. A servo cylinder 402 is fixedly connected to the mounting platform 401. The output end of the servo cylinder 402 is fixedly connected to the gripper 701. The mounting platform 401 is fixedly connected to the positioning slide 304 through a connecting plate. The gripper 701 includes a pneumatic gripper 7010. A conical block 7011 is rotatably connected to the top of the suspended ball 501. The pneumatic gripper 7010 grips and fixes the suspended ball 501 through the conical block 7011. A funnel sleeve 403 is fixedly installed on the sealing cover 400. The funnel sleeve 403 passes through the sealing cover 400 and the water-absorbing pad 702. The liquid outlet end of the filling port 202 is sleeved inside the funnel sleeve 403. Mounting plate 302 is slidably connected to linear slide 301 via a slide cylinder, driving the movement of filling port 202 and sealing cap 400. This allows sealing cap 400 to close or open filling container 3. When it is necessary to release the frothing component 500 into filling container 3, pneumatic gripper 7010 releases conical block 7011, and simultaneously releases chemical liquid into filling container 3 through filling port 202. This ensures the chemical liquid is released first, followed by the frothing component 500, preventing direct collision between the frothing component 500 and the bottom of filling container 3, thus avoiding damage to the frothing component. In the event of damage to component 500, after the chemical liquid is filled, the conical block 7011 is fixed by the pneumatic gripper 7010. Since the conical block 7011 and the suspended ball 501 are in a rotatable connection, when the gas impacts the scraper 502, it can drive the scraper 502 and the suspended ball 501 to rotate. Through the setting of the servo cylinder 402, the scraper component 500 is driven to move upward, so that the scraper 502 enters the inclined groove 703. Through the setting of the pneumatic gripper 7010, the scraper component 500 can be quickly fixed and gripped.
