DETAILED DESCRIPTION

[0016] The lower ash tank with anti-blocking function includes a tank body 1, a gas distributor 7, an ash discharge pipe 4, a pressure-assisting valve 10, an air inlet valve 11 and an upper ash pipe 2 (see the attached manual). Figure 1 ).

[0017] The tank body 1 is provided with an upper ash pipe 2; the upper end of the upper ash pipe 2 is located at the upper end of the tank body 1, and the lower end of the upper ash pipe 2 passes through the bottom of the tank body 1 and is provided with an ash inlet valve 3 (see the attached manual). Figure 1 When working, the material can enter the tank body 1 through the ash inlet valve 3 and the upper ash pipe 2.

[0018] The lower end of the tank body 1 is provided with a plurality of ash discharge pipes 4 in a divergent shape. The ash discharge pipes 4 extend to the outside of the tank body 1 and are provided with ash discharge valves 5 (see the attached manual). Figure 1 During operation, the material stored in the tank body 1 can be discharged through the ash discharge pipe 4.

[0019] A gasification bed (not shown in the drawings of the specification) is installed inside the tank body 1 below the ash discharge pipe 4; the gasification bed is an externally purchased device. When working, compressed gas enters the inside of the gasification bed and is dispersed in the gasification bed, so that the material in the tank body 1 can be kept in an airflow state under the action of air pressure.

[0020] The lower end of the tank body 1 is provided with a gas distributor 7 (see the attached manual) through a support plate 6. Figure 1 and2 The lower end of the gas distributor 7 is provided with an exhaust valve 8; the exhaust valve 8 is connected to the gasification bed inside the tank body 1 through a gasification pipe 9 (see the attached manual). Figure 1 During operation, the compressed gas can enter the interior of the gasification bed through the gas distributor 7, the exhaust valve 8 and the gasification pipe 9.

[0021] A plurality of booster valves 10 are provided at the lower end of the gas distributor 7; the booster valves 10 are connected to the ash discharge pipe 4 through a pipeline; a booster branch pipe 15 is installed on the ash discharge pipe 4 on one side of the exhaust valve 8 (see the attached manual). Figure 4 The pressure-assisting branch pipe 15 is connected to the interior of the ash discharge pipe 4; the upper end of the pressure-assisting branch pipe 15 is connected to the pressure-assisting valve 10 through a pipeline (see the attached manual). Figure 3 and 4 When working, the air distributor 7 can inject compressed air into the ash discharge pipe 4 through the booster valve 10 and the booster branch pipe 15, so as to increase the air pressure in the ash discharge pipe 4 and solve the problem that the ash discharge valve 5 is easily blocked.

[0022] A plurality of air inlet valves 11 are mounted on one side of the air distributor 7 (see the attached manual). Figure 3 ). The models of the various air inlet valves 11 are different, so that the connection requirements of different external compressed gas supply devices and the gas distributor 7 can be met.

[0023] The gas distributor 7 is provided with a safety valve 12 and a pressure gauge 13; the bottom of the gas distributor 7 is provided with a drain valve 14 (see the attached manual). Figure 3 ).

[0024] The tank body 1 is provided with a vent pipe 16; the upper end of the vent pipe 16 is located at the upper end of the tank body 1, and the lower end of the upper ash pipe 2 passes through the bottom of the tank body 1 and is provided with a vent valve 17 (see the attached manual). Figure 1 During operation, the air in the tank body 1 can be discharged through the vent pipe 16 and the vent valve 17.

[0025] The ash lower tank with anti-blocking function can solve the problem of easy blockage of the ash discharge pipe 4 by pressurizing the ash discharge pipe 4 through the design of the air distributor 7 and the ash discharge pipe 4, thereby solving the problem of easy blockage of the existing ash lower tank, and is particularly suitable for use in oil fields and cement ash storages.
