Technical Field

[0001] The utility model relates to a material conveying device, in particular to a calcined petroleum coke material conveying device. Background Art

[0002] In the process of preparing aluminum trichloride, petroleum coke needs to be put into the chlorination furnace according to weight for reaction, and in the process of petroleum coke transportation, a specified weight of petroleum coke needs to react with alumina;

[0003] In the process of conventionally transporting petroleum coke, the petroleum coke needs to be transported to the storage tank through the pneumatic conveying system, and then transported from the storage tank to the intermediate bin for weighing and discharging, and then enters the furnace silo together with alumina for mixing; the conventional calcined petroleum coke material conveying device often has only one intermediate bin, and the intermediate bin can only be used for discharging or feeding alone, which will not affect the weighing of the petroleum coke discharge; however, the setting of the intermediate bin often prolongs the transportation time of the entire device, that is, the feeding and discharging to the intermediate bin are intermittent;

[0004] In summary, how to shorten the time of transporting petroleum coke materials has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to shorten the time of transporting petroleum coke materials;

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The utility model discloses a calcined petroleum coke material conveying device, comprising: a storage tank, which is suitable for storing petroleum coke; a plurality of petroleum coke conveying pipe chains arranged in series, one end of which is connected to the bottom outlet of the storage tank, and the other end is connected to a material distribution system; a first intermediate material bin and a second intermediate material bin with the same structure, both of which are connected to the outlet of the material distribution system; a first loss-in-weight scale, which is arranged at the bottom outlet of the first intermediate material bin; a second loss-in-weight scale, which is arranged at the bottom outlet of the second intermediate material bin; a first mixed furnace material conveying pipe chain, which is connected to the bottom outlet of the first loss-in-weight scale; a second mixed furnace material conveying pipe chain, which is connected to the bottom outlet of the second loss-in-weight scale; wherein the material distribution system passes the petroleum coke into the first intermediate material bin or the second intermediate material bin;

[0008] In this scheme, two intermediate silos, two loss-in-weight scales, and two mixed furnace charge conveying pipes are provided. The petroleum coke can be transported to the first intermediate silo or the second intermediate silo through the material dividing system. When the first intermediate silo is weighing and discharging, the second intermediate silo is feeding. When the second intermediate silo is full, the material dividing system is used to switch, and the second intermediate silo is weighing and discharging, and the first intermediate silo is feeding. In this way, continuous discharge of the storage tank can be achieved, shortening the time for transporting petroleum coke materials.

[0009] In order to illustrate the specific structure of the material distribution system, the utility model adopts the material distribution system comprising: a feed channel, which is connected to the petroleum coke conveying pipe chain; a first discharge channel and a second discharge channel, whose tops are connected to the feed channel and whose bottoms are connected to the first intermediate silo or the second intermediate silo; wherein a reversing valve is provided at the first discharge channel, the second discharge channel and the feed channel. ;

[0010] The feed channel, the first discharge channel and the second discharge channel are in a "human" shaped structure. A reversing valve is provided in the feed channel. By switching the reversing valve, petroleum coke can enter the first intermediate silo through the feed channel and the first discharge channel, or petroleum coke can enter the second intermediate silo through the feed channel and the second discharge channel.

[0011] In order to realize the discharge of the first intermediate silo, the second intermediate silo, the first loss-in-weight scale, and the second loss-in-weight scale, the utility model adopts a pneumatic butterfly valve at the outlet of the first intermediate silo and the second intermediate silo; a pneumatic flap valve is provided at the outlet of the first loss-in-weight scale and the second loss-in-weight scale;

[0012] The pneumatic butterfly valve and pneumatic flap valve are in the normally closed state. When the petroleum coke needs to be discharged, the pneumatic butterfly valve and the pneumatic flap valve are started successively. The petroleum coke first enters the corresponding intermediate silo, and after weighing, it enters the corresponding mixed furnace material conveying pipe chain.

[0013] In order to achieve rapid discharge of the corresponding intermediate silo and accurate weighing of the loss-in-weight scale, the utility model adopts a buffer silo between the first loss-in-weight scale and the first intermediate material, and between the second loss-in-weight scale and the second intermediate silo; a fast feeding screw is provided at the inlet above the buffer silo, and a slow discharging screw is provided at the outlet below the buffer silo;

[0014] By setting up a buffer bin, a fast feed screw and a slow discharge screw are arranged in the buffer bin. The fast feed screw rotates quickly, so that the petroleum coke can quickly enter the buffer bin from the corresponding intermediate bin, and the slow discharge screw rotates slowly, so that the petroleum coke can slowly enter the corresponding buffer bin onto the corresponding loss-in-weight scale. The slow discharge screw can slowly drop the petroleum coke onto the loss-in-weight scale, so that the weight of the petroleum coke measured by the loss-in-weight scale can be more accurate.

[0015] Since the petroleum coke is transported into the storage tank by pneumatic means, in order to filter the gas and powder entering the storage tank, the utility model adopts a bag dust collector disposed on the top of the storage tank;

[0016] The use of bag dust collector can filter impurities in gas and powder to prevent impurities from entering the corresponding intermediate warehouse.

[0017] In order to illustrate how the petroleum coke conveying pipe chain is connected to the storage tank, the utility model adopts a star-shaped feeder provided at the bottom of the storage tank to be connected to the petroleum coke conveying pipe chain;

[0018] The petroleum coke conveying pipe chain and the bottom outlet of the storage tank can be connected through the star feeder.

[0019] The beneficial effects of the utility model are as follows: the utility model is a calcined petroleum coke material conveying device, which is provided with two intermediate silos, two loss-in-weight scales, and two mixed furnace material conveying pipes. The petroleum coke can be conveyed to the first intermediate silo or the second intermediate silo through the material dividing system. When the first intermediate silo is weighing and discharging, the second intermediate silo is feeding. When the second intermediate silo is full, the material dividing system is used for switching. At this time, the second intermediate silo is weighing and discharging, and the first intermediate silo is feeding. In this way, continuous discharging of the storage tank can be achieved, which shortens the time for conveying petroleum coke materials. BRIEF DESCRIPTION OF THE DRAWINGS
