[0021] The present utility model will be further described below in conjunction with the embodiments and the drawings:
[0022] Embodiment 1: As shown in Figure 1 、 2 and 4, the material airtight conveying pipeline loss reduction device includes a dust bin 1, a pneumatic conveying silo pump 2, and a compressed air storage tank 3. A down ash pipeline 4 is fixedly connected between the bottom outlet of the dust bin 1 and the top inlet of the pneumatic conveying silo pump 2. An air pipeline is fixedly connected between the upper inlet of the pneumatic conveying silo pump 2 and the outlet of the compressed air storage tank 3. The bottom outlet of the pneumatic conveying silo pump 2 is fixedly connected with an ash conveying pipeline. The air pipeline includes a first air pipeline section 5 and a second air pipeline section 6. An air regulating plate 7 is arranged between the first air pipeline section 5 and the second air pipeline section 6. A plurality of air regulating holes 8 are arranged at intervals along the circumference in the middle of the air regulating plate 7. The right end of the first air pipeline section 5, the air regulating plate 7, and the left end of the second air pipeline section 7 are connected together by flanges.
[0023] By arranging the air regulating plate 7 in the present utility model, the compressed air in the air pipeline enters the pneumatic conveying silo pump 2 evenly and at a constant speed, thereby controlling the gas volume and flow rate of the compressed air, effectively avoiding the abrasion and erosion of the ash conveying pipeline caused by a large gas volume and a fast flow rate, reducing the maintenance frequency and maintenance cost, and improving the operation efficiency of the ash conveying device.
[0024] According to actual needs, the above-mentioned material airtight conveying pipeline loss reduction device can be further optimized or / and improved:
[0025] Embodiment 2: The difference from Embodiment 1 is that: as shown in Figure 1 、 3 and 5, it further includes a dust blocking net 9. The ash conveying pipeline includes a first ash conveying pipe section 10, an anti-blocking pipe section 11, and a second ash conveying pipe section 12. A dust blocking net 9 is arranged between the anti-blocking pipe section 11 and the second ash conveying pipe section 12. The right end of the first ash conveying pipe section 10 and the left end of the anti-blocking pipe section 11 are connected together by flanges. The right end of the anti-blocking pipe section 11, the dust blocking net 9, and the left end of the second ash conveying pipe section 12 are connected together by flanges.
[0026] During use, by setting up the dust blocking net 9, foreign matters such as ash blocks are intercepted in the anti-blocking pipe section 11. Utilizing the compressed air scouring during pneumatic ash conveying, the ash blocks and other foreign matters are broken up, ensuring the normal operation of pneumatic ash conveying. And the tar separated from the purified ash is intercepted by the dust blocking net 9. After regularly cleaning the dust blocking net 9, the smooth operation of pneumatic ash conveying can be ensured; By setting the installation method of flange connection, it is convenient to remove the anti-blocking pipe section 11 and then clean foreign matters such as ash blocks and tar lumps intercepted by the dust blocking device, effectively solving the problem of difficult maintenance after the ash conveying pipeline is blocked in the existing calcium carbide furnace purification system.
[0027] Example 3: The difference from Example 2 is that as shown in the attached Figure 1 、 2 figure, it further includes gaskets. There are gaskets between the right end of the first air conveying pipe section 5 and the air regulating plate 7, between the air regulating plate 7 and the left end of the second air conveying pipe section 6, between the left end of the first ash conveying pipe section 10 and the anti-blocking pipe section 11, between the right end of the anti-blocking pipe section 11 and the dust blocking net 9, and between the dust blocking net 9 and the left end of the second ash conveying pipe section 12.
[0028] During use, by using gaskets for sealing, air leakage is prevented from causing equipment failures. According to requirements, the gasket can be an asbestos gasket.
[0029] Example 4: The difference from Examples 2 to 3 is that as shown in the attached Figure 1 、 2 figure, it further includes a maintenance window 13. There is a maintenance opening on the outer side of the middle part of the anti-blocking pipe section 11, and a maintenance window 13 is installed on the outer side of the anti-blocking pipe section 11 corresponding to the position of the maintenance opening.
[0030] During use, by setting up the maintenance window 13, foreign matters such as ash blocks and tar lumps in the blocked ash conveying pipeline can be taken out without disassembling the flange.

By setting the air cannon 17, after reaching the set pressure, the exhaust port of the air cannon 17 discharges high-pressure gas into the ash bin 1 for reverse blowing to blow down the accumulated and adhered dust, keeping the ash bin 1 unobstructed. The vibration motor 16 and the air cannon 17 can enhance dust removal and greatly reduce the situation of dust accumulation in the ash bin 1.
[0034] As required, on each pipeline and equipment of the material closed conveying pipeline loss reduction device, conventional valves, thermometers, pressure gauges, etc. well-known and commonly used in the art can also be set according to production needs.
[0035] The above technical features constitute the embodiments of the present utility model, which have strong adaptability and implementation effects. Non-essential technical features can be increased or decreased according to actual needs to meet the requirements of different situations.
