Description

Technical Field

[0001] This utility model belongs to the technical field of emulsion explosive production equipment, specifically a filling and auxiliary material device for emulsion explosive production. Background Technology

[0002] In the field of industrial explosives, emulsion explosives, with their excellent water resistance, reliable safety, and superior explosive performance, have been widely used in numerous industries such as mining and water conservancy projects. In the production process of emulsion explosives, the additive filling stage is a crucial link. The precision of additive addition and the uniformity of mixing are like the foundation of a building, directly and profoundly affecting the final quality and performance of the emulsion explosive.

[0003] However, current auxiliary material filling devices for emulsion explosive production have revealed some significant limitations in practical applications. Firstly, some devices struggle to achieve precise metering during the auxiliary material addition process. This is akin to the inability to accurately control the amount of seasoning used in cooking, leading to deviations in the amount of auxiliary material added, which severely affects the stability of emulsion explosive quality, resulting in inconsistent product quality across different batches. Secondly, after prolonged use, residual materials inside the equipment act like hidden "time bombs," potentially interfering with subsequent production and further reducing product quality, increasing production risks. Summary of the Invention

[0004] To address the problems existing in the background art, this utility model provides a filling device for emulsion explosive production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filling device for emulsion explosive production, comprising a shell, connecting pipes, heating pipes, pipe one, L-type three-way ball valve, check valve, pipe two, flow meter, screw pump, stirring mechanism, temperature control mechanism, cleaning mechanism and control mechanism;

[0006] The upper end of the housing is connected to a connecting pipe. A stirring mechanism is provided inside the housing. A heating tube is provided on the bottom surface of the housing. The heating tube is electrically connected to a temperature control mechanism. The temperature control mechanism is fixed on the housing. The housing is connected and fixed to one end of an L-shaped three-way ball valve through a first pipe. The other end of the L-shaped three-way ball valve is connected and fixed to a cleaning mechanism. The lower end of the L-shaped three-way ball valve is connected and fixed to one end of a second pipe. A one-way valve is provided inside the second pipe. A flow meter is provided below the one-way valve. The flow meter is installed on the second pipe. The other end of the second pipe is connected and fixed to a screw pump. The flow meter is electrically connected to the screw pump through a control mechanism.

[0007] The stirring mechanism includes a rotating rod, a motor, and two stirring units;

[0008] One end of the rotating rod is rotatably connected to the bottom surface of the housing, and the other end of the rotating rod is fixedly connected to an output shaft of the motor. Two stirring units are provided on the side wall of the rotating rod, and the two stirring units are arranged symmetrically.

[0009] Each of the stirring units includes a crossbar, a scraper, and multiple stirring rods;

[0010] One end of the crossbar is fixedly connected to the rotating rod, and the other end of the crossbar is fixedly connected to the scraper. The scraper is slidably disposed in contact with the inner wall of the shell, and multiple stirring rods are fixed on the side wall of the crossbar.

[0011] The temperature control mechanism includes a temperature sensor, a PID controller, and an actuator;

[0012] The temperature sensor is connected to the PID controller, the PID controller is connected to the actuator, and the actuator is electrically connected to the heating tube. The temperature sensor, PID controller, and actuator are all fixed on the housing, and the probe of the temperature sensor extends into the housing in a sealed manner.

[0013] The cleaning mechanism includes a pipe, a water tank, a vent pipe, valves, and a fan;

[0014] One end of the third pipe is connected and fixed to an L-shaped three-way ball valve, and the other end of the third pipe is sealed and fixed to a water tank. One end of the vent pipe is connected and fixed to the third pipe, and the other end of the vent pipe is connected and fixed to a blower. A valve is provided on the vent pipe.

[0015] The control mechanism includes a PLC controller and a frequency converter;

[0016] The flow meter is connected to the PLC controller via signal, the PLC controller is connected to the frequency converter via signal, and the frequency converter is electrically connected to the motor on the screw pump.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Precise and efficient mixing to ensure raw material quality: The stirring mechanism is driven by a motor to rotate the rod, which in turn drives the symmetrically arranged stirring units. The stirring rods evenly distributed on the crossbar can stir the auxiliary materials from all directions and multiple angles, so as to achieve full mixing of the auxiliary materials and provide a uniform raw material base for the production of emulsion explosives. At the same time, the scraper that is in contact with the inner wall of the shell can remove the auxiliary materials that stick to the wall in time, avoid uneven mixing caused by local accumulation of auxiliary materials, reduce raw material waste, improve raw material utilization, and ensure product quality stability.

[0019] 2. Intelligent temperature control system for optimized production conditions: The temperature control mechanism utilizes temperature sensors, PID controllers, and actuators to construct a closed-loop control system. It can accurately monitor and adjust the temperature inside the shell in real time. The temperature sensor has a measurement range of 0℃ - 100℃, which meets the temperature control requirements for emulsion explosive production. The PID controller dynamically adjusts the heating tube power based on temperature deviation, ensuring that heat is evenly transferred to the auxiliary materials. This effectively reduces the viscosity of the auxiliary materials, creates favorable conditions for subsequent processing, ensures smooth production, and reduces production problems caused by improper temperature.

[0020] 3. Stable flow delivery and improved production accuracy: In the auxiliary material delivery process, flow meters (such as electromagnetic flow meters) can accurately detect the flow rate in real time. Combined with an intelligent adjustment system composed of a PLC controller and a frequency converter, the screw pump speed can be automatically adjusted according to the preset flow value to achieve precise control of the auxiliary material flow rate. The one-way valve in the second pipeline effectively prevents the auxiliary material from flowing back, ensuring a stable and reliable delivery process. This makes the amount of auxiliary material added in the production of emulsion explosives precise and controllable, improving the production accuracy and consistency of the product.

[0021] 4. Integrated cleaning and drying enhances equipment adaptability: The cleaning mechanism switches between water and air circuits via an L-shaped three-way ball valve. After the auxiliary materials are conveyed, the cleaning water in the water tank can be used to quickly flush the pipes, thoroughly removing residual auxiliary materials and avoiding cross-contamination of raw materials between different batches of production. After cleaning, the fan and air pipe work together to quickly dry the pipes, shortening equipment preparation time, improving equipment turnover efficiency, enhancing the adaptability of the equipment to different production tasks, and reducing the intensity and time cost of manual cleaning.

[0022] In summary, this emulsion explosive production material filling device, through innovative design and coordinated operation of multiple links such as stirring, temperature control, conveying, and cleaning, achieves high efficiency, precision, safety, and stability in the production process. It not only improves product quality and production efficiency but also reduces production costs and safety risks, demonstrating significant practical value and promotional significance.

[0039] The workflow of this emulsion explosive production auxiliary material filling device mainly covers several key aspects: auxiliary material conveying and mixing, temperature control, auxiliary material conveying and flow regulation, and pipeline cleaning and drying. Each aspect works closely together to ensure that the emulsion explosive auxiliary materials can be conveyed and processed efficiently and stably. The specific working principle is as follows:

[0040] The auxiliary materials for making emulsion explosives are transported into the housing 1 through connecting pipe 2. Connecting pipe 2 and the upper end of housing 1 are connected by a flange, which provides good sealing and effectively prevents leakage of the auxiliary materials during transport. The transport of the auxiliary materials is accomplished by an external pump, which draws the auxiliary materials from the raw material storage container and stably delivers them into housing 1 through connecting pipe 2. Motor 4 is started by an external power source. Motor 4 is securely fixed to the top of housing 1 by a motor bracket to ensure the stability of motor operation. The output shaft of motor 4 drives the rotating rod 3 to rotate. This drives two symmetrically arranged stirring units to rotate. One end of the crossbar 5 in each stirring unit is welded and fixed to the rotating rod 3, and the other end is connected and fixed to the scraper 7 by bolts. The stirring rods 6 are evenly arranged on the crossbar 5. This design can ensure that the auxiliary materials are fully stirred and mixed evenly. The scraper 7 is made of wear-resistant and corrosion-resistant rubber material. Its shape is adapted to the inner wall of the shell 1. It slides along the inner wall of the shell 1 to scrape off the auxiliary materials attached to the inner wall in time, preventing the auxiliary materials from sticking to the wall and ensuring the stirring effect and production efficiency. The inner wall of the shell 1 is made of heat insulation material.

[0041] Temperature sensor 8 is activated, its probe extending sealed into housing 1, accurately detecting the actual temperature of the auxiliary materials. Temperature sensor 8 has a measurement range of 0℃ - 100℃, meeting the temperature control requirements of emulsion explosive production. Temperature sensor 8 monitors the temperature inside housing 1 in real time and transmits the temperature information to PID controller 9 in the form of an electrical signal. The required temperature value is preset in PID controller 9 (e.g., ...). BTC706-R and REX-C100 Based on the deviation between the actual temperature transmitted by temperature sensor 8 and the preset temperature, the actuator (e.g., model) outputs a control signal to actuator 10. ZDZ-1000 (Model) The heating power of heating tube 11 is controlled according to the signal.

[0042] The heating element 11 adopts resistance heating and is set at the bottom of the shell 1, which can evenly transfer heat to the auxiliary materials, improve heating efficiency and uniformity. Through reasonable adjustment of the PID controller 9, for example, according to the temperature change in the actual heating process, the PID parameters are gradually optimized to achieve precise control of the temperature inside the shell 1, reduce the stickiness of the auxiliary materials, and ensure the smooth progress of the subsequent production process.

[0043] Rotate the L-type three-way ball valve 13 to connect pipe 12 and pipe 2 15. Start the screw pump 17 with an external power supply. The screw pump 17 is selected based on parameters such as the viscosity and flow rate requirements of the auxiliary material to ensure stable delivery of the auxiliary material. The auxiliary material in the housing 1 flows through pipe 12, L-type three-way ball valve 13, and pipe 2 15 in sequence, and finally flows out from the screw pump 17.

[0044] During the auxiliary material conveying process, flow meter 16 can be an electromagnetic flow meter. Its measurement principle is based on Faraday's law of electromagnetic induction, which can detect the flow rate of auxiliary materials in real time and accurately, and transmit the flow information to the PLC controller (e.g., Siemens S7-1200 , S7-300 and S7-400 series PLC (etc.), the PLC controller compares the received flow rate value with a preset value. When the flow rate is too high or too low, the PLC controller adjusts the output signal to the frequency converter in real time according to the flow rate deviation (e.g., Delta VFD-M inverter model and Mitsubishi FR-E700 frequency converter (etc.), the frequency converter controls the speed of the second motor on the screw pump 17 according to the signal, thereby precisely adjusting the flow rate of the screw pump 17. The one-way valve 14 in the second pipeline 15 can effectively prevent the backflow of auxiliary materials when the flow rate of the screw pump 17 changes, ensuring the stability of the conveying process.

[0045] After the auxiliary materials are transported, turn off the screw pump 17, rotate the L-type three-way ball valve 13 to the position where pipe 3 18 and pipe 2 15 are connected, and restart the screw pump 17. The cleaning water in the water tank 19 passes through pipe 3 18, L-type three-way ball valve 13, and pipe 2 15 in sequence, and is finally discharged through the screw pump 17. The cleaning removes the residual auxiliary materials in the pipes. After cleaning, start the blower 22 with an external power supply. The blower 22 can provide sufficient airflow for drying. At the same time, open the valve 21 on the vent pipe 20. Air passes through the vent pipe 20, pipe 3 18, L-type three-way ball valve 13, and pipe 2 15 in sequence to quickly dry the inside of the cleaned pipes, preparing them for the next use.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
