Description

Technical Field

[0001] This utility model relates to the technical field of fire extinguishing agent production equipment, and in particular to a filling device for fire extinguishing agent production. Background Technology

[0002] In the production of fire extinguishing agents, the material conveying process before filling directly affects production efficiency and product quality. Currently, commonly used fire extinguishing agent delivery systems in the industry mainly employ a single-function structure, making it difficult to adapt to the delivery needs of various high-viscosity fire extinguishing agents such as dry powder, water-based, and foam, resulting in the following prominent problems: Dry powder extinguishing agents clumping and clogging: When dry powder extinguishing agents (such as ABC dry powder) are left to stand in the storage tank, they are prone to clumping due to the adsorption force between particles (the diameter can reach 5-10mm). Traditional stirring devices can only achieve simple mixing and cannot effectively break up the clumps, resulting in blockage of the delivery pipeline. Frequent shutdowns and manual cleaning are required, which seriously affects the continuity of production. Adhesion of liquids and viscous materials to pipe walls: Water-based fire extinguishing agents, foam liquids, etc., have a certain viscosity and are prone to adhering to the inner wall of the pipe during transportation due to surface tension, forming a residual layer of 0.5-2mm thickness. Existing smooth pipe designs lack active anti-adhesion mechanisms, which not only causes material waste (single batch loss rate of 3%-5%), but also affects the purity of the next filling due to the deterioration of the residual material. Dead zones and cross-contamination in pipelines: Blind spots exist at bends (90° elbows), valve interfaces, and other locations in the delivery pipeline, where materials (especially high-viscosity foam liquids) easily accumulate. Traditional delivery systems lack cleaning structures designed for these dead zones, allowing accumulated materials to undergo chemical changes over time, leading to cross-contamination between different batches of extinguishing agents and reducing product qualification rates to below 90%. Therefore, developing a product that integrates anti-caking, anti-adhesion, and dead-angle cleaning functions is key to solving the above-mentioned technical pain points and is of great significance for improving the production efficiency of fire extinguishing agents and reducing costs. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a filling device for fire extinguishing agent production that can solve the problems of integrated anti-caking, anti-adhesion, and dead corner cleaning.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filling device for producing fire extinguishing agent, comprising a storage tank, a delivery pipe and a pulse mechanism, wherein the delivery pipe is disposed below the storage tank and the pulse mechanism is disposed below the delivery pipe; The pulse mechanism includes a bend, a nozzle, and a pulse generator. The nozzle is fixedly installed at the bend of the bend, and the pulse generator is fixedly installed at the right end of the nozzle. The bend is fixedly connected to the pulse generator located at the right end of the nozzle. A drive motor is fixedly connected to the upper end of the storage tank, and a stirring mechanism is fixedly installed inside the storage tank.

[0005] Preferably, the stirring mechanism includes a rotating shaft and a micro vibrator, with the upper end of the rotating shaft fixedly connected to the output end of the drive motor; Three blades are fixedly connected to the outer wall of the rotating shaft, and are arranged in a circumferential array. Preferably, an electrically controlled valve is fixedly installed between the storage tank and the delivery pipe, and a flange connection is provided below the electrically controlled valve, with the storage pipe being snapped into the delivery pipe located below the flange connection.

[0006] Preferably, the spiral guide plate inside the feed pipe extends spirally along the pipe axis.

[0007] Preferably, a miniature vibrator is fixedly installed on the blade near the rotating shaft, and silicone is fitted around the edge of the blade.

[0008] Preferably, a circular support plate is fixedly connected to the support rod, and three support rods are arranged in a circumferential array. A support base is fixedly installed below the support rod. The support rod is fixedly connected to the storage tank within the circular support plate.

[0009] Preferably, a spiral guide plate is fixedly installed inside the conveying pipe, an electromagnetic coil is fixedly installed on the conveying pipe, a flange pipe is provided below the conveying pipe, and a pressure sensor is installed inside the conveying pipe. The pulse mechanism is snapped into the delivery pipe mounted on the same flange.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The filling device for producing fire extinguishing agent uses a drive motor to rotate a rotating shaft. Three paddles in a circular array rotate synchronously at an adjustable speed of 5-30 r / min. The silicone sleeves on the edges of the paddles fit tightly against the inner wall of the storage tank, forcibly scraping away residues of viscous materials such as foam liquid from the tank wall. At the same time, a micro vibrator on the side of the paddles near the rotating shaft generates a high-frequency vibration of 50-100Hz, which can break up dry powder clumps with a diameter of ≥5mm within 3 seconds, ensuring that the material is uniformly loose.

[0011] The filling device for producing the fire extinguishing agent controls the flow rate by adjusting the opening and closing time of the electrically controlled valve at the bottom of the storage tank through a PLC-linked metering system. The material enters the lower conveying pipe through a flange connection. The spiral guide plate inside the conveying pipe guides the material to form a spiral flow, reducing local stagnation caused by turbulence. At the same time, the electromagnetic coil on the outer wall generates a 20kHz high-frequency vibration, causing the pipe to produce a micron-level amplitude, which breaks the molecular adsorption force between the material and the pipe wall. Especially for water-based fire extinguishing agents, the adhesion amount is reduced by more than 60%.

[0012] The filling device for producing the extinguishing agent, when flowing through the pulse mechanism below the delivery pipe, the nozzle at the bend of the pipe is connected to a 0.3-0.5MPa high-pressure air source through a pulser. It sprays focused airflow enhanced by a 45° cone-angle nozzle at a default frequency of 0.1 seconds every 5 seconds to remove residual material ≤0.2g accumulated in the dead corner of the bend. If the pressure sensor in the delivery pipe detects a pressure ≥0.2MPa, indicating possible blockage, the PLC immediately increases the pulser spray frequency to 0.1 seconds every 2 seconds and simultaneously increases the vibration intensity of the electromagnetic coil until the pressure returns to normal.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a filling device for fire extinguishing agent production, including a storage tank 1, a conveying pipe 6 and a pulse mechanism, wherein the conveying pipe 6 is disposed below the storage tank 1 and the pulse mechanism is disposed below the conveying pipe 6; The pulse mechanism includes a bend 10, a nozzle 9, and a pulser 7. The nozzle 9 is fixedly installed at the bend of the bend 10, and the pulser 7 is fixedly installed at the right end of the nozzle 9. The bend 10 is fixedly connected to the pulser 7 located at the right end of the nozzle 9. A drive motor 8 is fixedly connected to the upper end of the storage tank 1. A stirring mechanism is fixedly installed inside the storage tank 1, including a rotating shaft 11, a blade 13 and a micro vibrator 12. The upper end of the rotating shaft 11 is fixedly connected to the output end of the drive motor 8. Three blades 13 are fixedly connected to the outer wall of the rotating shaft 11, and are arranged in a circumferential array. A micro vibrator 12 is fixedly installed on the side of the blade 13 near the rotating shaft 11. The edge of the blade 13 is fitted with silicone 14. The drive motor 8 drives the rotating shaft 11 to rotate. The three blades 13 in the circumferential array rotate synchronously at an adjustable speed of 5-30 r / min. The silicone 14 fitted on the edge of the blade fits tightly against the inner wall of the storage tank 1, forcibly scraping away the residue of sticky materials such as foam liquid on the tank wall. At the same time, the micro vibrator 12 (model: FP-50-UT) on the side of the blade 13 near the rotating shaft 11 generates a high frequency vibration of 50-100Hz, which can break up dry powder clumps with a diameter ≥5mm within 3 seconds, ensuring that the material is uniformly loose. An electrically controlled valve 4 is fixedly installed between the storage tank 1 and the conveying pipe 6. A flange pipe 5 is installed below the electrically controlled valve 4, and the storage pipe 1 is snapped into the conveying pipe 6 installed below the flange pipe 5. A spiral guide plate 16 is fixedly installed inside the conveying pipe 6, and an electromagnetic coil 15 is fixedly installed on the conveying pipe 6. A flange pipe 5 is installed below the conveying pipe 6. A pressure sensor (model: MS5803-14BA) is installed inside the conveying pipe 6. The flow rate is controlled by adjusting the opening and closing time of the electric valve 4 at the bottom of the storage tank 1 through the PLC linkage metering system. The material enters the conveying pipe 6 below through the flange pipe 5. The spiral guide plate 16 inside the conveying pipe 6 guides the material to form a spiral flow, reducing local stagnation caused by turbulence. At the same time, the electromagnetic coil 15 on the outer wall generates a 20kHz high-frequency vibration, which causes the pipe to generate a micron-level amplitude, destroying the molecular adsorption force between the material and the pipe wall. Especially for water-based fire extinguishing agents, the adhesion amount is reduced by more than 60%. The pulse mechanism is connected to the conveying pipe 6, which is set on the same flange pipe 5. When the flow passes through the pulse mechanism below the conveying pipe 6, the nozzle 9 at the bend of the bend pipe 10 is connected to a 0.3-0.5MPa high-pressure air source through the pulser 7. It sprays focused airflow enhanced by the 45° cone angle nozzle at a default frequency of 0.1 seconds every 5 seconds to remove the residual material accumulated in the dead corner of the bend pipe with a content ≤0.2g. If the pressure sensor in the conveying pipe 6 detects a pressure ≥0.2MPa, indicating possible blockage, the PLC immediately increases the spray frequency of the pulser 7 to 0.1 seconds every 2 seconds, and at the same time increases the vibration intensity of the electromagnetic coil 15 until the pressure returns to normal. A circular support plate 2 is fixedly installed on the lower part of the outer wall of the storage tank 1. A support rod 3 is fixedly connected to the circular support plate 2, and four rods are arranged in a circular array. A support base is fixedly connected to the lower part of the support rod 3.

[0020] Working principle: The pretreatment stage in storage tank 1 ensures the initial state of the material through a dual action: the drive motor 8 drives the rotating shaft 11 to rotate, and the three paddles 13 in the circumferential array rotate synchronously at a speed of 5-30 r / min adjustable. The silicone 14 sleeved on the edge of the paddles fits tightly against the inner wall of storage tank 1, forcibly scraping away the residue of sticky materials such as foam liquid on the tank wall. At the same time, the micro vibrator 12 on the side of the paddle 13 near the rotating shaft 11 generates a high-frequency vibration of 50-100Hz, which can break up dry powder clumps with a diameter ≥5mm within 3 seconds, ensuring that the material is uniformly loose. The pre-treated material enters the conveying pipe 6 for enhanced conveying: the opening and closing time of the electrically controlled valve 4 at the bottom of the storage tank 1 is adjusted by the PLC linkage metering system to control the flow rate, and the material enters the lower conveying pipe 6 through the flange pipe 5. The spiral guide plate 16 in the conveying pipe 6 guides the material to form a spiral flow state, reducing the local stagnation caused by turbulence. At the same time, the electromagnetic coil 15 on the outer wall generates a 20kHz high-frequency vibration, which makes the pipe generate a micron-level amplitude, destroying the molecular adsorption force between the material and the pipe wall. Especially for water-based fire extinguishing agents, the adhesion amount is reduced by more than 60%. Finally, the material enters the pulse mechanism to complete the cleaning and output: When flowing through the pulse mechanism below the conveying pipe 6, the nozzle 9 at the bend of the pipe 10 is connected to a 0.3-0.5MPa high-pressure air source through the pulser 7. It sprays focused airflow enhanced by the 45° cone-angle nozzle at a default frequency of 0.1 seconds every 5 seconds to remove the residual material accumulated in the dead corner of the bend pipe with a content ≤0.2g. If the pressure sensor in the conveying pipe 6 detects a pressure ≥0.2MPa, indicating possible blockage, the PLC immediately increases the spray frequency of the pulser 7 to 0.1 seconds every 2 seconds, and at the same time increases the vibration intensity of the electromagnetic coil 15 until the pressure returns to normal.

[0021] Structural Description: Storage Tank 1: As the core container of the device, it is used to hold the extinguishing agent material to be filled, providing material storage space for the entire filling process. It is the basic load-bearing component for pretreatment, transportation and filling, ensuring a continuous supply of materials. Circular support plate 2: It is fixedly installed on the lower outer wall of storage tank 1 and is used to connect storage tank 1 and support rod 3. The circular structure can evenly distribute the weight of storage tank 1, avoid local stress concentration that could cause deformation of storage tank, and improve the support stability of storage tank. Support rod 3: It is fixedly connected to the circular support plate 2 in a circular array (4 rods). The lower end is connected to the support base. The 4 circularly distributed support rods disperse the overall weight of the device from multiple directions, enhance the overall stability of the device, and prevent it from tipping over due to vibration or changes in material weight during operation. Drive motor 8: Fixed at the upper end of storage tank 1, with its output end connected to rotating shaft 11, providing power to rotating shaft 11 and blade 13, driving blade to rotate to achieve material pretreatment, and serving as the power source for stirring, scraping off residues and breaking up clumps; Rotating shaft 11: The upper end is connected to the output end of the drive motor 8, and the outer wall is fixed with blades 13 to transmit the power of the drive motor and drive the blades to rotate synchronously, ensuring that the blades evenly cover the space inside the storage tank. Blade 13: There are 3 blades in total, fixed on the outer wall of the rotating shaft 11 in a circular array. The rotation speed is adjustable from 5 to 30 r / min. The circular array design ensures that all areas of the material can be stirred. The adjustable speed can adapt to extinguishing agents with different viscosity and agglomeration degree, improve the flexibility of pretreatment, and ensure the uniformity of the material. Miniature vibrator 12: Fixed on the side of the blade 13 near the rotating shaft 11, it generates 50-100Hz high-frequency vibration. The high-frequency vibration can break up dry powder clumps with a diameter ≥5mm within 3 seconds, ensuring that the material is loose and uniform, and avoiding clumps from affecting subsequent conveying and filling accuracy. Silicone 14: It is fitted onto the edge of the blade 13 and fits tightly against the inner wall of the storage tank 1. The silicone material is soft and elastic, which can forcefully scrape off the sticky material (such as foam liquid) remaining on the tank wall, while avoiding scratching the tank wall, reducing material waste and tank wall contamination. Electrically controlled valve 4: Installed between storage tank 1 and conveying pipe 6, it is controlled by PLC-linked metering system. By adjusting the opening and closing time, it can accurately control the material flow rate, realize precise control of filling volume, and improve filling accuracy. Flange connection 5: Located below the electric control valve 4 and the conveying pipe 6, it is used to connect the storage tank 1 to the conveying pipe 6 and the conveying pipe 6 to the pulse mechanism. The flange connection has strong sealing performance to prevent material leakage, and at the same time, it is easy to disassemble and install, which is conducive to later maintenance and component replacement. Conveying pipe 6: Connecting flange pipe 5, with built-in spiral guide plate 16, pressure sensor, and electromagnetic coil 15 fixed on the outer wall, serving as a material conveying channel. In conjunction with the internal guide structure and external vibration components, it optimizes the material flow state and reduces residue and blockage. Spiral guide plate 16: Fixed inside the conveying pipe 6, it guides the material to form a spiral flow, reduces local stagnation caused by turbulence, makes the material flow more evenly in the pipe, and reduces the risk of blockage; Electromagnetic coil 15: Fixed on the outer wall of the delivery pipe 6, it generates a 20kHz high-frequency vibration, causing the pipe to generate a micron-level amplitude, which destroys the molecular adsorption force between the material and the pipe wall (especially for water-based fire extinguishing agents), reducing the amount of adhesion by more than 60%, reducing material waste and pipe blockage. Bend 10 (pulse mechanism): Serves as the channel for the pulse mechanism, connecting to the conveying pipe 6. The nozzle 9 is installed at the bend, realizing the change of material conveying direction, providing a structural basis for the nozzle to clean dead corners, and ensuring that the material is smoothly turned and output. Nozzle 9: Fixed at the bend of the bend 10, it adopts a 45° cone angle design and is connected to the pulse generator 7. The 45° cone angle can focus the high-pressure airflow, enhance the cleaning of the dead corner of the bend, and improve the removal effect of residual materials. Pulse 7: Fixed at the right end of nozzle 9, connected to a 0.3-0.5MPa high-pressure air source, with adjustable jet frequency (default 0.1 seconds every 5 seconds, 0.1 seconds every 2 seconds when blocked), providing high-pressure airflow power. The default frequency can clear the dead corner residue of the bend pipe (≤0.2g). When blocked, the frequency is increased, and the vibration is enhanced in conjunction with the electromagnetic coil to quickly solve the blockage problem and ensure smooth material conveying. Pressure sensor (inside delivery pipe 6): Installed inside delivery pipe 6, it is used to detect the pressure inside the pipe and monitor pressure changes in real time. When the pressure is ≥0.2MPa, it indicates possible blockage and provides a signal for PLC to control the pulse frequency and electromagnetic coil strength, so as to realize timely handling of blockage.
