Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a liquid chemical raw material filling system. Background Technology

[0002] After production, chemical raw materials need to be piped into chemical raw material drums before being sold. In related technologies, pumps are typically used to pump the chemical raw materials from the raw material pool into a main pipeline, which then branches into multiple sub-channels for filling multiple chemical raw material drums. During the filling process, the chemical raw material drums are weighed to calculate the filling volume. Valves are installed on each sub-channel to control the flow. However, during the filling process, chemical liquids inevitably leak into the air, polluting the environment. When chemical raw materials need to be transported from outside the factory, filling becomes more complicated, requiring them to be filled into a raw material pool first. Utility Model Content

[0003] The purpose of this invention is to provide a liquid chemical raw material filling system to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A liquid chemical raw material filling system includes a filling room, an exhaust system at the top of the filling room, a purifier connected to the exhaust system, and a tank truck. A fixed bracket is installed at the front end of the top of the filling room. A cylinder is vertically mounted on the front side of the fixed bracket. An open section is provided at the front of the filling room. A sealing plate is slidably installed on the front of the filling room. The top of the sealing plate is fixedly connected to the bottom of the cylinder's telescopic rod. A through hole is provided at the top right side of the filling room. A first conveying pipe is fixedly installed in the through hole. A metering device is fixedly installed at the bottom of the filling room. A packaging barrel is installed on top of the metering device. A filling valve is detachably installed on the top of the packaging barrel. A position actuator is vertically mounted on the top of the filling valve. The bottom of the position actuator is fixedly connected to the top of the filling valve. The top of the position actuator is fixedly connected to the top of the filling room. The right side of the filling valve is connected to the outlet of a ball valve via the first conveying pipe. The inlet of the ball valve is connected to the connector of the tank truck via a second conveying pipe.

[0006] By adopting the above technical solution, the packaging process is set up indoors. The top of the packaging room is equipped with a ventilation system for absorbing toxic and harmful gases. The entire packaging room is sealed. The sealing plate on the front of the packaging room can be moved up and down by a cylinder set on a fixed bracket. A metering device is set at the bottom of the packaging room. The metering device is set in a ground recess, and the top of the metering device is flush with the ground to facilitate the packaging barrels to be pushed to the top of the metering device. The entire packaging room is kept sealed throughout the filling process, and air is continuously drawn into the purifier. After filling, the air in the packaging room remains clean. The tank truck responsible for transporting chemical raw materials is connected to the filling valve through a delivery pipe. The delivery pipe is connected to a ball valve, which allows the delivery pipe to rotate up and down, thus facilitating the connection between the delivery pipe and the liquid inlet of the tank truck. This method is convenient, efficient, and very safe in situations where external filling of chemical raw materials is required.

[0007] In a further embodiment, the top of the dispensing room is provided with a through hole, one end of a ventilation pipe is fixedly installed at the through hole, the other end of the ventilation pipe is connected to the top of the purifier, a fan is fixedly installed in the end of the ventilation pipe near the dispensing room, the fan is used to draw the exhaust gas in the filling process away from the purifier along the ventilation pipe, and a demister is fixedly installed on the top of the purifier.

[0008] By adopting the above technical solution, the demister on the top of the purifier can separate fine droplets in the air. In conjunction with the purifier, it can filter out chemical components adsorbed by the droplets in the air, and the air with the chemical components removed will be circulated back into the environment from the top of the purifier.

[0009] In a further embodiment, the purifier includes a packing section, a liquid storage section, and a mounting frame. The liquid storage section is fixedly mounted on the top of the mounting frame. A first liquid inlet is provided on the top of the liquid storage section. The packing section is fixedly mounted on the top of the liquid storage section. Packing material is detachably mounted in the middle of the packing section. A second liquid inlet is provided on one side of the top of the packing section. A second liquid outlet is provided in the middle of the bottom of the packing section. The second liquid outlet is connected to the first liquid inlet through a first circulating liquid pipe. A first liquid outlet is provided on one side of the liquid storage section. A water pump is fixedly mounted on the mounting frame. The first liquid outlet is connected to the third liquid inlet of the water pump through a second circulating liquid pipe. The third liquid outlet of the water pump is connected to the second liquid inlet through a third circulating liquid pipe.

[0010] By adopting the above technical solution, the purifier consists of two parts. The packing section contains packing material with space above and below it. The liquid storage section stores absorbent liquid that can absorb chemical components. A water pump pumps the absorbent liquid to the top of the packing section, causing it to fall slowly. Air containing toxic and harmful gases enters from the bottom of the packing section, with most of it rising and entering the packing filled with absorbent liquid. After being filtered by the packing material, the air containing absorbent liquid enters the demister. The demister removes trace amounts of absorbent liquid from the air, ultimately resulting in clean air. The absorbent liquid itself can also be continuously circulated.

[0011] In a further embodiment, one end of the third circulating liquid pipe is connected to the third outlet of the water pump, and the other end of the third circulating liquid pipe is located inside the packing part. A spray nozzle is fixedly installed on the end of the third circulating liquid pipe located inside the packing part, and the nozzle of the spray nozzle is set vertically downward.

[0012] By adopting the above technical solution, the absorbent liquid can be sprayed more evenly onto the upper part of the entire packing section through the spray head, avoiding uneven contact between toxic and harmful gases and absorbent liquid, thus making the purification effect of the purifier more stable and effective.

[0013] In a further embodiment, the sealing plate is composed of a metal frame and a PTEP plate, and a sealing strip is provided around the periphery of the metal frame.

[0014] By adopting the above technical solution, the overall weight of the metal frame is relatively light. The PTEP plate is placed on the back of the metal plate. PTEP material has good corrosion resistance. Together with the rubber sealing strip, it can effectively isolate the dispensing room and prevent the gas leaked from harming the operators.

[0015] In a further embodiment, the bottom of the packaging barrel is provided with multiple casters.

[0016] By adopting the above technical solution, the packaging barrels are used to hold large amounts of chemical liquids, and the casters make them easy to move, which can effectively improve production efficiency.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By setting up filling valve and ball valve, the angle of the infusion pipe can be adjusted by the flexible ball valve to adapt to tank trucks of different heights, and the filling valve connected to the ball valve can perform the final filling of the packaging barrels, eliminating the need for transfer through raw material pools, thereby improving the efficiency of chemical raw material transportation and filling.

[0019] 2. By setting up a demister and a purifier, air containing absorbent liquid can be introduced into the demister, which will filter out trace amounts of absorbent liquid from the air, thus ultimately eliminating chemical substances in the air.

[0020] 3. By setting up packaging barrels and metering equipment, the packaging barrels can be pushed onto the metering device for filling, achieving accurate quantitative filling and rapid transfer after completion. Attached Figure Description

[0026] Example:

[0027] like Figures 1-2As shown, a liquid chemical raw material filling system includes a filling room 1, an exhaust system 2 on the top of the filling room 1, a purifier 3 connected to the exhaust system 2, and a tank truck. A fixed bracket 4 is installed at the front end of the top of the filling room 1. A cylinder 5 is vertically installed on the front side of the fixed bracket 4. An open section is provided on the front side of the filling room 1. A sealing plate 6 is slidably installed on the front side of the filling room 1. The top of the sealing plate 6 is fixedly connected to the bottom of the telescopic rod of the cylinder 5. The sealing plate 6 consists of a metal frame 61 and a P... The assembly consists of TEP plates 62. A sealing strip is provided around the periphery of the metal frame 61. A through hole is provided at the top right side of the dispensing room 1, and a first conveying pipe is fixedly installed inside the through hole. A metering device 7 is fixedly installed at the bottom of the dispensing room 1. A packaging drum 8 is mounted on top of the metering device 7. Multiple casters 13 are provided at the bottom of the packaging drum 8. A filling valve 9 is detachably mounted on the top of the packaging drum 8. A position actuator 10 is vertically mounted on the top of the filling valve 9. The bottom of the position actuator 10 is fixedly connected to the top of the filling valve 9, and the top of the position actuator 10 is fixedly connected to the top of the dispensing room 1. The right side of the filling valve 9 is connected to the outlet of the ball valve 11 through the first delivery pipe, and the inlet of the ball valve 11 is connected to the connector of the tank truck through the second delivery pipe. Through the tank truck and the filling valve 9, the chemical raw materials transported from the tank truck to the dispensing room 1 can be input into the ball valve 11 through the infusion pipe. Since the model of the tank truck responsible for transportation may be different each time, the ball valve 11 mainly helps the infusion pipe to better adjust its position so as to connect with the outlet of the tank truck. The sealing plate 6 composed of the metal frame 61 and the PTEP plate 62 can effectively seal the dispensing room 1. The switch can also be controlled by a button. After pressing the button, the cylinder 5 on the fixed bracket 4 at the top of the dispensing room 1 will lift the sealing plate 6, so as to facilitate pushing the packaging barrel 8 onto the metering device. The metering device then accurately detects the packaging barrel 8 to ensure that the weight of the filled chemical raw materials is kept within the rated range.

[0028] like Figures 1-2As shown, the top of the dispensing room 1 is provided with a through hole, and one end of a ventilation pipe is fixedly installed at the through hole. The other end of the ventilation pipe is connected to the top of the purifier 3. A fan is fixedly installed inside the end of the ventilation pipe near the dispensing room 1. The fan is used to draw the exhaust gas during the filling process away from the purifier 3 along the ventilation pipe. A demister 12 is fixedly installed on the top of the purifier 3. The purifier 3 includes a packing part 31, a liquid storage part 32, and a mounting frame 33. The liquid storage part 32 is fixedly installed on the top of the mounting frame 33. A first liquid inlet is provided on the top of the liquid storage part 32. The packing part 31 is fixedly installed on the top of the liquid storage part 32. Packing is detachably installed in the middle of the packing part 31. A second liquid inlet is provided on one side of the top of the packing part 31. A second liquid outlet is provided in the middle of the bottom of the packing part 31. The second liquid outlet is connected to the first liquid inlet through a first circulating liquid pipe. A demister 12 is provided on one side of the liquid storage part 32. The device has a first liquid outlet. A water pump 34 is fixedly installed on the mounting bracket 33. The first liquid outlet is connected to the third liquid inlet of the water pump 34 through a second circulating liquid pipe. The third liquid outlet of the water pump 34 is connected to the second liquid inlet through a third circulating liquid pipe. One end of the third circulating liquid pipe is connected to the third liquid outlet of the water pump 34, and the other end of the third circulating liquid pipe is located inside the packing part 31. A spray nozzle is fixedly installed on the end of the third circulating liquid pipe located inside the packing part 31. The nozzle of the spray nozzle is set vertically downward. Through the packing part 31 and the liquid storage part 32, air containing toxic and harmful gases can be absorbed by the absorbent liquid filling the packing part 31 when it passes through it. The absorbent liquid is continuously pumped to the top of the packing part 31 by the water pump 34, and then continuously permeates into the entire packing from top to bottom. The bottom end of the packing part 31 is connected to the top end of the liquid storage part 32. The absorbent liquid will eventually circulate continuously in the purifier 3 and will not be lost.

[0029] Specific implementation process: First, press the button on one side of the filling room 1 to make the cylinder 5 lift the sealing plate 6 upward and push the packaging barrel 8 onto the metering device in the filling room 1. The position actuator 10 fixes the filling valve 9 to the packaging barrel 8. After fixing, the personnel leave the filling room 1 and close the sealing plate 6 again. At this time, wait for the tank truck to stop at the designated position. The ball valve 11 can make the connection between the infusion pipe and the outlet of the tank truck smoother. The chemical raw materials enter the ball valve 11 through the infusion pipe and then enter the filling valve 9 through the ball valve 11, and finally enter the packaging barrel. The metering device will calculate the weight of the chemical raw materials in the packaging barrel. When the weight reaches the standard, the filling will stop. During the entire filling process, the exhaust system 2 operates continuously, continuously drawing the air in the filling room 1 to the purifier 3, then purifying it through the purifier 3, and then discharging it into the atmosphere.

[0030] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
