Description

Technical Field

[0001] This utility model relates to the field of textile chip raw material conveying technology, and in particular to a dustproof chip particle dilute phase conveying system. Background Technology

[0002] In the production of nylon 6 chips, the granulated chips need to be conveyed to an extraction tower for extraction. When the height of the extraction tower is higher than the height of the granulation equipment, a dilute phase conveying system is required to transport the chip particles to the top of the extraction tower.

[0003] The existing conveying system simply transports the slices into the pipeline system, then uses a Roots blower 1 to draw in air from the outside, compresses it, and blows it into the pipeline system. This then transmits power to the slice particles, which are carried by the flowing air to the top of the extraction tower. The slices then enter the extraction tower for extraction, while the air is discharged to the outside, completing the entire conveying process.

[0004] In the aforementioned existing technology, during the slice delivery process, the blower needs to draw air from the external environment, making it easy for environmental dust to be introduced into the slices, affecting the purity of the slices and the quality of subsequent products. The particles drawn in by the blower can sometimes be large and accumulate over time, easily causing the Roots blower blades to jam and become damaged.

[0005] If a fine filter that meets the filtration requirements is installed on the blower's air intake pipe, this type of filter is prone to clogging and requires frequent shutdowns for cleaning, affecting the continuity of production. If a filter with a larger mesh is used, the filtration effect cannot meet the requirements for slice conveying. In order to meet the requirements for slice conveying volume, the requirements for air pressure and air intake volume are also high. The filter will affect the stability of air pressure and significantly reduce the air velocity, thus affecting slice conveying.

[0006] Based on this, the present invention designs a dustproof dilute phase conveying system for sliced ​​particles to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a dustproof dilute phase conveying system for sliced ​​particles. This device adds a buffer tank, a buffer bag, and a limiting frame. The gas is filtered through the buffer bag and the limiting frame, and the bag is not completely blocked. The intercepted particles are mainly on the outer surface of the bag. When cleaning is required, the pressure regulating valve is separated from the buffer tank, the bag is turned over and placed outside the buffer tank, and then the impurities are shaken and cleaned. The filtration effect is good, the cleaning is convenient, and the buffer tank has the advantages of short downtime. In addition, this method provides stable pressure and very low impurity levels. Basically, it only needs to be maintained during normal synchronous maintenance when the production line is under repair, and no separate shutdown for cleaning is required.

[0008] This invention is achieved as follows: a dustproof dilute phase conveying system for sliced ​​particles, comprising: Buffer tank, pressure regulating valve, blower, and extraction tower; The buffer tank is a closed tank, and a pressure regulating valve is installed on the air inlet pipe of the buffer tank; The buffer tank is equipped with a limiting frame and a buffer bag inside. The limiting frame is a wire mesh frame, and the buffer bag is a breathable cloth bag. The limiting frame is fitted over the buffer bag. The front opening of the buffer tank, and the vent pipe of the pressure regulating valve extends into the front opening of the buffer tank in a sealed manner. The air inlet of the blower is connected to the air outlet of the buffer tank, and the rear air outlet pipe of the blower is connected to a cyclone separator, which is located above the extraction tower. The blower is also connected to a slice storage tank at its rear end, and the outlet of the slice storage tank is sealed to the pipeline between the cyclone separator and the blower.

[0009] Furthermore, the pressure regulating valve is a self-regulating valve.

[0010] Furthermore, the blower is a Roots blower.

[0011] Furthermore, the limiting frame is a closed wire mesh frame with an opening at the front end; The buffer bag is a closed cloth bag, and the opening of the buffer bag is tied and sealed to the air outlet of the pressure stabilizing valve. The air outlet of the pressure stabilizing valve and its fitted buffer bag are both placed inside the limiting frame.

[0012] Furthermore, a rotary valve is provided at the outlet of the slicing tank, and the slicing tank is connected to the conveying pipeline of the blower through the rotary valve.

[0013] The beneficial effects of this utility model are: 1. This utility model adds a buffer bag and a limiting frame. The buffer bag performs secondary filtration of the external air and is set inside the buffer tank. It does not affect the storage micro pressure of the buffer tank and maintains stable pressure, providing higher pressure for the subsequent blower and also providing cleaner air. 2. The buffer bag of this device is flexible and is placed inside the front opening of the buffer tank. It can be easily disassembled and flipped open during cleaning, and can be directly flipped out of the buffer tank without entering the buffer tank for cleaning, making cleaning and maintenance simpler and more convenient. 3. This device has added a buffer tank. The buffer tank has high internal pressure but no obvious airflow. Therefore, the buffer tank can also isolate foreign objects inside, so that they fall down and will not rise with the airflow into the subsequent process, further reducing the possibility of impurities entering the slice conveying system.

[0015] Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a top view of the internal structure of the buffer bag and limiting frame of this utility model in the buffer tank.

[0016] The attached diagram lists the components represented by each number as follows: 1-Buffer tank, 11-Limit frame, 12-Buffer bag, 2-Pressure regulator, 3-Blower, 31-Slice storage tank, 4-Extraction tower, 41-Cyclone separator. Detailed Implementation

[0017] Please see Figures 1 to 2 As shown, this utility model provides a dustproof dilute phase conveying system for sliced ​​particles. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0018] In a specific embodiment of the technical solution of this utility model: Includes buffer tank 1, pressure regulating valve 2, blower 3, and extraction tower 4; The buffer tank 1 is a closed tank. A pressure regulating valve 2 is installed on the air inlet pipe of the buffer tank 1. The front end of the air inlet pipe of the pressure regulating valve 2 is connected to the external clean compressed air. The pressure regulating valve 2 is directly connected to the clean external compressed air pipeline, using a clean air source, which significantly improves the cleanliness of the system. The pressure regulating valve 2 is a self-regulating valve, which can control the air pressure of the buffer tank 1 to be stable and can also meet the air pressure requirements of the blower 3.

[0019] The buffer tank 1 is equipped with a limiting frame 11 and a buffer bag 12. The limiting frame 11 is a mesh frame and the buffer bag 12 is a breathable cloth bag. The limiting frame 11 is fitted over the buffer bag 12. The limiting frame 11 is a closed mesh frame with an opening at the front end. The limiting frame 11 only serves to support the buffer bag 12 and prevent it from moving inward and detaching. The buffer bag 12 is a closed cloth bag, which is the filter layer of the cloth bag. The opening of the buffer bag 12 is tied and sealed to the air outlet of the pressure regulator 2. The air outlet of the pressure regulator 2 and the buffer bag 12 are both placed inside the limiting frame 11.

[0020] The front opening of the buffer tank 1 is sealed with the vent pipe of the pressure regulating valve 2, which extends into the front opening of the buffer tank 1. The buffer bag 12 is also tied to the vent pipe of the pressure regulating valve 2 and extends directly into the buffer tank 1 together. The front opening of the buffer tank 1 and the pressure regulating valve 2 can be sealed with a flange or other pipe joint, and the buffer bag 12 can be inserted together. The buffer bag 12 and the vent pipe of the pressure regulating valve 2 can be tied tightly with straps, so the buffer bag 12 can be turned out from the front opening of the buffer tank 1, making it easy to clean the impurities from the bag. Moreover, the impurities can be cleaned by shaking. Blower 3 is a Roots blower. The air inlet of blower 3 is connected to the air outlet of buffer tank 1. Blower 3 is located at the rear end of buffer tank 1. The air outlet pipe at the rear end of blower 3 is connected to cyclone separator 41. Cyclone separator 41 is located above extraction tower 4. The rear end of the blower 3 is also connected to the slice storage tank 31, and the outlet of the slice storage tank 31 is sealed to the pipeline between the cyclone separator 41 and the blower 3.

[0021] The discharge port of the slicing storage tank 31 is also equipped with a rotary valve. The slicing storage tank 31 is connected to the conveying pipeline of the blower 3 through the rotary valve, which facilitates the control of the amount of slices injected into the pipeline system to match the air pressure of the blower 3.

[0022] When this utility model is in use, the pressurized gas in the external clean pipeline enters the buffer tank 1 through the pressure regulating valve 2.

[0023] Furthermore, during this gas delivery process, the gas source itself is relatively clean, and then the gas source is intercepted and filtered again through the buffer bag 12. The buffer bag 12 is confined within the range of the limiting frame 11, and after being inflated, the buffer bag 12 presses against the inner wall of the limiting frame 11, thereby constraining and supporting the buffer bag 12. The gas is pressurized inside the buffer bag 12, stabilizing the pressure inside the entire buffer tank 1. The buffer bag 12 can filter the airflow, filtering the already clean air again, ensuring that the airflow that finally comes into contact with the slice particles remains clean and free of impurities.

[0024] The buffer tank 1 maintains a stable air pressure, which enables it to provide a stable pressurized clean airflow to the blower 3, and the airflow from the blower 3 is blown towards the cyclone separator 41.

[0025] The slice storage tank 31 conveys the slice particles to the subsequent air outlet duct of the blower 3. The airflow from the blower 3 blows the slice particles into the cyclone separator 41, where the slice particles are separated from the air. Then, the slice particles enter the extraction tower 4. The slice particles in the extraction tower 4 are clean, which is beneficial for subsequent processes.

[0026] It avoids the influence of dust in the caulking air, prevents the blower 3 equipment from jamming, and effectively avoids problems such as abnormal product quality and production interruption caused by cleaning.

[0027] This clean air is directly connected to the buffer tank 1. The buffer bag 12 can basically complete the maintenance cycle of the entire set of equipment. When cleaning the buffer bag 12 of this device, you only need to remove the front opening of the buffer tank 1, disconnect the pipeline of the pressure regulating valve 2, and take out the buffer bag 12 at the same time. Then remove the buffer bag 12, turn it over, shake it, and vacuum it. You can also rinse it to clean the buffer bag 12. The sturdy filter screen can only be removed by entering the buffer tank 1 and then the entire filter device needs to be cleaned. Because personnel enter the buffer tank 1, the buffer tank 1 also needs to be scrubbed again. However, the buffer bag 12 of this device is flexible and can be removed along with the pressure regulating valve 2. When maintaining the buffer tank 1, you only need to rinse it with water. There is no need for personnel to enter the interior for scrubbing. The operation and maintenance are more convenient.
