Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to an automatic flow regulating device for material conveying. Background Technology

[0002] In industries such as chemical, food processing, and pharmaceutical, material conveying systems are a key link in achieving continuous production. Especially for long-distance, high-flow liquid or slurry conveying scenarios (such as chemical raw material transportation and slurry preparation in food processing), it is necessary to ensure flow stability and conveying efficiency. Currently, due to high fluid resistance and significant pressure attenuation, long-distance conveying pipelines usually require the addition of a booster pump in the middle of the pipeline to maintain the conveying pressure.

[0003] However, the operation and flow regulation of the intermediate booster pump rely on manual intervention. A separate operating station needs to be set up at the booster pump, and a dedicated person needs to monitor the pressure and flow parameters in real time, which increases labor costs. Therefore, we need to propose an automatic flow regulation device for material conveying. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] An automatic flow control device for material conveying includes a first storage tank 1. A discharge pipe 2 is fixedly connected to the outer wall of the first storage tank 1. The discharge pipe 2 is made of 304 stainless steel with a polished inner wall to reduce material residue and corrosion risk. The bottom of the first storage tank 1 is designed with a conical structure to facilitate concentrated material discharge. By setting a sealed connection between the first storage tank 1 and the discharge pipe 2 and the conical bottom design, the device achieves the effect of preventing material accumulation and improving discharge efficiency. At the same time, the stainless steel material ensures the corrosion resistance and service life of the pipeline. One end of the discharge pipe 2 is fixedly connected to a first conveying pipe 3. One end of the first conveying pipe 3 is fixedly connected to a transfer tank 4. The bottom end of the transfer tank 4 is fixedly connected to a second conveying pipe 5. One end of the second conveying pipe 5 is fixedly connected to a second storage tank 6. The top of the second storage tank 6 is fixedly connected to a first level gauge 7. A first solenoid valve 8 (model: ASCO 8320G) is conductively connected to the outer wall of the second conveying pipe 5. The first solenoid valve 8 is connected to a first conveying pump 9 (model: Grundfos). The CR10-6 pump body adopts magnetic drive technology to achieve leak-free operation. The second transfer pump 11 (model: Wilo MVIE 25 / 1-7) is connected in parallel to the first transfer pipe 3 as a backup pump to improve system redundancy. By setting up an ASCO solenoid valve and a Grundfos magnetic pump, precise start-up and shutdown and zero-leakage delivery are achieved. The backup pump design ensures the stability of continuous production and avoids downtime due to single pump failure.

[0022] Furthermore, a first conveying pump 9 is connected to the second conveying pipe 5. Through the coordinated use of the first storage tank 1, discharge pipe 2, first conveying pipe 3, transfer tank 4, second conveying pipe 5, second storage tank 6, first level gauge 7, first solenoid valve 8, and first conveying pump 9, when the first level gauge 7 detects that the liquid level inside the second storage tank 6 is lower than a preset value, the first solenoid valve 8 opens, and the first conveying pump 9 pumps the material from the transfer tank 4 into the second storage tank 6. When the liquid level reaches the preset value, the first solenoid valve 8 closes, and the first conveying pump 9 stops working. This achieves fully automatic control, replacing manual operation, saving labor costs per pipeline, and improving the reliability, economy, and automation level of the device. The first level gauge 7 (model: VEGAVegaflex) 86) The system monitors the liquid level of the second storage tank 6 in real time. When the liquid level is lower than the preset value, the first solenoid valve 8 is triggered to open and the first delivery pump 9 is started. After the liquid level reaches the upper limit, the system automatically closes the valve and stops the pump. By setting the VEGA level gauge and the automatic control logic, the system achieves the effect of unattended operation and fully automatic material replenishment, which significantly reduces the need for manual intervention and the risk of operational errors.

[0023] The outer wall of the first conveying pipe 3 is covered with a heat insulation pad, and the first conveying pipe 3 is connected to a second solenoid valve 10. The outer wall of the first conveying pipe 3 is covered with an aluminum silicate fiber heat insulation pad (thickness 20mm, thermal conductivity ≤0.035W / m·K) and fixed by clamps. The second solenoid valve 10 is a DN50 electric butterfly valve (model: VFD50-15P), which supports rapid opening and closing and remote control. By setting the aluminum silicate fiber heat insulation pad and the DN50 electric butterfly valve, the heat loss is reduced and the material temperature is kept stable. At the same time, the high response speed of the electric butterfly valve ensures the accuracy of flow regulation.

[0024] It also includes a second conveying pump 11, which is conductively connected to the outer wall of the first conveying pipe 3;

[0025] A second level gauge 12 is installed on the top of the transfer tank 4. The bottom of the second level gauge 12 is located inside the transfer tank 4. The second level gauge 12 is a radar level gauge 12 (model: E+H FMR250) with a measurement accuracy of ±1mm. The inner cylinder 16 is made of 316L stainless steel.

[0026] The second storage tank 6 is fixedly connected to a feed pipe 13 at one end. A third conveying pump 14 is installed on the feed pipe 13, and a feeding pipe 15 is fixedly connected to one end of the third conveying pump 14. The third conveying pump 14 is a screw pump (model: Seepex BN 25-12) equipped with a frequency converter and supports stepless flow adjustment. A drip-proof connector (material: PTFE) is installed at the end of the feeding pipe 15 to prevent material dripping and environmental pollution. By setting up a screw pump and frequency converter control, the system achieves the effect of adapting to the conveying of high-viscosity materials and energy-saving operation. The PTFE drip-proof connector further improves the environmental friendliness and safety of the system.

[0027] The transfer tank 4 has an inner cylinder 16 inside, and a receiving cavity 17 is reserved between the inner cylinder 16 and the transfer tank 4. The heat transfer oil filled in the receiving cavity 17 adjusts the power of the heating wire 18 through the PID temperature control module (accuracy ±0.5℃) to ensure that the material temperature is stable within the set range (e.g., 50℃±2℃). The outer wall of the inner cylinder 16 is welded with spiral guide vanes to enhance the circulation efficiency of the heat transfer oil. By setting PID temperature control and spiral guide vanes, the effect of precise temperature control and efficient heat transfer is achieved, avoiding changes in the properties of the material due to temperature fluctuations (e.g., solidification or decomposition). It is suitable for conveying temperature-sensitive materials such as food and chemicals.

[0028] The cavity 17 is equipped with a heat-conducting medium, and a heating wire 18 is fixedly connected inside the cavity 17. The heat-conducting medium is high-temperature heat-conducting oil (flash point ≥280℃), and the heating wire 18 is a nickel-chromium alloy heating wire 18 (power 3kW). By setting up a radar level gauge and an inner cylinder-heat-conducting oil heating system, high-precision level monitoring and uniform heating are achieved. The 316L stainless steel inner cylinder has strong corrosion resistance, and the circulating heating of the heat-conducting oil avoids local overheating or coking of the material.
