Description

Technical Field

[0001] The utility model relates to the field of discharging of steel plate silos or steel plate warehouses, in particular to a high unloading rate corridor-free multi-point discharging system for steel plate warehouses. Background Art

[0002] At present, domestic powder material resources are rich and widely used in construction, agriculture, chemical industry and other fields. At present, the market space for powder materials is huge. Affected by the market price in the off-season and peak season, most powder materials are stored in large steel plate warehouses. Because powder materials have a certain solubility and are easily affected by moisture and become hardened, the discharge of powder steel plate warehouses has always been the focus of steel plate warehouse design. At present, most of the unloading methods of steel plate warehouses are ground-type multi-corridor multi-point unloading or overhead multi-corridor multi-point unloading. Among them, the ground-type multi-corridor multi-point unloading steel plate warehouse has high investment cost and large excavation depth. When the groundwater level is shallow, the corridor is easy to contact with groundwater, which aggravates corrosion and affects its foundation life. In addition, the materials in the warehouse are very easy to get damp and become compacted. In addition, the overhead multi-corridor multi-point unloading steel plate warehouse has the advantage of not being easily affected by moisture compared with the ground-type steel plate warehouse, but it also has the disadvantages of long construction period and high construction risk. At the same time, although the overhead multi-corridor multi-point unloading can improve the unloading rate, the unloading only relies on the overall gravity discharge of the powder, and cooperates with the fluidizing rod to increase the fluidity of the material and reduce the possibility of blockage, but this still cannot be more advanced and efficient unloading, and the unloading rate is not high. Utility Model Content

[0003] The existing steel plate warehouses, whether floor-standing multi-corridor multi-point discharging or overhead multi-corridor multi-point discharging, can improve the unloading rate through their multi-point discharging, but they all rely on the gravity discharging of powder materials and cooperate with fluidizing rods to increase the fluidity of materials to reduce the possibility of blockage, but this still cannot be more advanced and more efficient unloading, and the unloading rate is not high. At least one aspect or one purpose of the present application can solve the above problems, and specifically designs a high unloading rate corridor-free multi-point discharging system for steel plate warehouses, and the technical solution adopted is:

[0004] A high unloading rate corridor-free multi-point discharge system for a steel plate warehouse, wherein the steel plate warehouse comprises a guide cone at the bottom, and a plurality of discharge ports are arranged between the guide cones, and a pressure reducing cone is arranged at each discharge port. The discharge system comprises:

[0005] An air delivery pipe is arranged along the periphery of the steel plate warehouse and a plurality of fluidizing rods are laid on the upper surface of the guide cone, and the plurality of fluidizing rods are connected to the air delivery pipe;

[0006] The multiple discharge ports are arranged in multiple rows, and the multiple discharge ports in each row are arranged in a straight line;

[0007] A feeding pipe is horizontally connected to each discharge port, the feeding pipe is connected to the steel plate warehouse, one end of the feeding pipe is connected to the outlet of a switch valve, and the inlet end of the switch valve is the connection end.

[0008] Preferably, one inlet end of the multiple switch valves connected to the multiple material delivery pipes is commonly connected to an air intake pipe, and the air intake pipe is connected to an external air source.

[0009] Preferably, each material delivery pipe is connected to a flexible pipe at one end away from the switch valve, and the flexible pipes correspondingly connected to the plurality of material delivery pipes are correspondingly connected to a material discharge pipe.

[0010] Preferably, the flexible pipe is a corrugated plastic pipe or a corrugated steel pipe.

[0011] Preferably, the gas delivery pipe is connected to each fluidizing rod via an air supply pipeline, and each air supply pipeline is provided with a valve.

[0012] Preferably, the valve is an on-off regulating valve for regulating the gas flow.

[0013] Preferably, the gas supply pipeline and the material delivery pipe can be made of welded pipes, seamless steel pipes, stainless steel pipes, etc.

[0014] The utility model can improve the suspension effect of materials in the process of discharging from the steel plate warehouse by arranging the air delivery pipe and the fluidizing rod, reduce the compaction of materials at the discharge port, reduce the material agglomeration phenomenon, and improve the discharging efficiency. In addition, a delivery pipe is arranged at the discharge port of the steel plate warehouse, and high-pressure gas is blown into the delivery pipe to quickly transport powder materials. This discharging method is more efficient, more advanced, and has a high unloading rate for powder materials in the warehouse. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-4 As shown, a high unloading rate corridor-free multi-point discharge system for a steel plate warehouse, the steel plate warehouse 1 includes a guide cone 3, a discharge port 12 and a pressure reducing cone 4 at the bottom, and also includes a lower reinforced concrete base 2 for bearing the load of the upper steel structure and the material in the warehouse, the guide cone 3 is arranged above the reinforced concrete base 2, and can be filled with aerated blocks, mixed materials or other materials, the guide cone 3 has an angle of ≥10°, and is mainly used for guiding the discharge of powder in the warehouse, and there are multiple discharge ports 12 between the guide cones 3, and each discharge port 12 is provided with a pressure reducing cone 4, and the structure of the pressure reducing cone 4 is composed of existing steel sections and steel plates, which can reduce the resistance of powder flow, reduce the accumulation and compaction degree of powder, and prevent the material from producing a core-pulling effect when unloading.

[0022] The above-mentioned discharge port 12 is a discharge channel for powder materials. The specific number of the discharge ports 12 can be set in combination with the diameter of the warehouse. In order to improve the wear resistance of the discharge port 12, wear-resistant steel plates made of Q355B material can be used at the discharge port to increase the service life.

[0023] The above-mentioned discharging system includes an air pipe 7 arranged along the periphery of the steel plate warehouse 1 and a plurality of fluidizing rods 6 laid on the upper surface of the guide cone 3. The plurality of fluidizing rods 6 are connected to the air pipe 7. One end of the air pipe 7 is connected to an external air source. The so-called air source is a blower equipment that generates high pressure using a Roots blower, an air-suspended centrifugal blower, an air compressor, etc. A plurality of discharge ports 12 are arranged in multiple rows, and the plurality of discharge ports 12 in each row are arranged in a straight line. The linear arrangement of the discharge ports 12 is for the convenience of setting the feed pipe 5.
