Technical Field

[0001] The utility model relates to the technical field of heat storage ball conveying equipment, in particular to a heat storage ball pneumatic conveying device. Background Art

[0002] Currently, aluminum smelting furnaces in the aluminum processing and recycling industries generally utilize regenerative combustion technology. Regenerative combustion aluminum balls require timely cleaning and replacement to ensure heat storage. Most methods of replacing regenerative balls involve manual feeding. This is due to the high volume of balls required for replacement and the high labor intensity. Furthermore, the operation requires high temperatures and harsh working conditions. Therefore, some companies use chain conveyors to load regenerative balls into the regenerative chamber. However, the regenerative chambers in aluminum smelting furnaces are generally quite high, and the chain conveyor's inclined feed stroke is long, occupying a large area and making placement difficult. Furthermore, if the inclination is too steep, the regenerative balls can easily roll off the chain conveyor, making it inconvenient and costly. Utility Model Content

[0024] Example 1:

[0025] This embodiment Figure 1 、 Figure 2 and Figure 3 As shown, a heat storage ball air delivery device includes a gas storage tank 1, an air delivery pipe 2, a bin-type ball feeder 3, and an air delivery pipe 4. The gas outlet end of the gas storage tank 1 is connected to the ball inlet of the air delivery pipe 4 through the air delivery pipe 2, the discharge nozzle of the bin-type ball feeder 3 is connected to the feed end of the air delivery pipe 4, and a plurality of heat storage balls 5 are stored in the bin-type ball feeder 3.

[0026] A certain amount of compressed gas is stored in the gas storage tank 1, and then the heat storage balls 5 to be released are placed in the bin-type ball feeder 3. Then the heat storage balls 5 roll one by one into the air delivery pipe 4 from the discharge nozzle of the bin-type ball feeder 3. Finally, the gas storage tank 1 is deflated, and the high-pressure gas pushes the heat storage balls 5 along the air delivery pipe 4 until they reach the regenerator of the aluminum smelting furnace.

[0027] Example 2:

[0028] On the basis of the above embodiment, this embodiment shows that the silo-type ball feeder 3 includes a silo body 6, a ball dividing cylinder 7 and a ball dividing plate 8, the ball dividing plate 8 is slidably installed in the discharge nozzle of the silo body 6, the ball dividing cylinder 7 is installed on the silo body 6, and the power output end of the ball dividing cylinder 7 is connected to the outer end of the ball dividing plate 8.

[0029] Considering that too many heat storage balls 5 may cause blockage at the discharge nozzle of the warehouse body 6, causing the heat storage balls at the feed end of the air supply pipe 4 to be stuck, during operation, under the control of the sensor, the ball distribution cylinder 7 can be started to push down the ball distribution plate 8 when the ball comes, to ensure that the heat storage balls 5 pass through freely and enter the air supply pipe 4 alone.

[0030] It is worth noting that, in order to ensure the pushing effect of the gas on the heat storage balls 5, the ball dividing plate 8 can also play a sealing role to prevent the gas from leaking from the bin-type ball feeder 3.

[0031] Preferably, the inner bottom surface of the bin body 6 is arranged to be inclined downward along the rolling direction of the heat storage balls 5 .

[0032] Through the action of gravity, the heat storage balls 5 roll on the inner bottom surface of the silo 6 toward the feed end of the air delivery pipe 4 without the need for additional power.

[0033] Preferably, a baffle 9 is provided on the inner top surface of the discharge nozzle of the silo body 6 .

[0034] The baffle 9 can block the heat storage balls 5 at the upper layer in the silo 6 to prevent the heat storage balls 5 from being blocked at the discharge nozzle of the silo 6.

[0035] Preferably, a baffle plate 10 is provided at the front end of the ball inlet of the air delivery pipe 4, and an air outlet is provided on the baffle plate 10.

[0036] The blocking plate 10 is used to prevent the heat storage balls 5 from rolling back from the air delivery pipe 4 into the gas transmission pipe 2 , thereby preventing excessive heat storage balls 5 from accumulating in the air delivery pipe 4 .

[0037] Preferably, a blocking plate 11 is slidably mounted on the ball opening of the air delivery pipe 4 , and the blocking plate 11 is connected to the power output end of the blocking cylinder 12 .

[0038] The blocking plate 11 is used to seal the ball opening of the gas delivery pipe 4 to prevent gas leakage and ensure the pushing effect of the gas on the heat storage ball 5.

[0039] Preferably, a pulse solenoid valve is installed on the gas delivery pipe 2.

[0040] The pulse solenoid valve controls the pulse operation of the device, saving energy and gas.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
