[0029] like Figures 1 to 3 As shown, this embodiment proposes a dust removal system for a grain unloading depot, which includes a grain unloading depot 1, in which a feeding port 11 is provided, and the feeding port 11 can be used to receive the unloading of grain from a container truck 7; an entrance and an exit (not shown in the accompanying drawings) are opened on the grain unloading depot 1, and the entrance and exit can be used for the container truck 7 to enter and exit, and in addition, a plurality of dust removal devices 2 are also provided in the grain unloading depot 1, and the dust removal devices 2 can be used to remove dust during the unloading process of the container truck 7; each dust removal device 2 is located on the same side as the entrance and exit, and in addition, a shifting member 3 is movably provided on the grain unloading depot 1, and the shifting member 3 is arranged corresponding to the position of the entrance and exit. In this way, by arranging a plurality of dust removal devices 2 in the grain unloading depot 1, dust can be removed during the unloading process of the container truck 7 when the container truck 7 enters through the inlet and outlet; by arranging the dust removal devices 2 on the same side as the inlet and outlet, it is beneficial for the wind to converge at the dust removal device, thereby ensuring the consistency of wind direction, avoiding air flow turbulence in the grain unloading depot 1, and improving the dust removal effect; by arranging the stopper 3 at the inlet and outlet, the inlet and outlet can be sealed by the stopper 3, so that the grain unloading depot 1 is in a sealed state as a whole, avoiding the dust removal being affected by natural wind during the dust removal process due to the opening of the grain unloading depot 1, further ensuring the consistency of wind direction, ensuring that the material does not fly everywhere during the unloading process, and greatly improving the dust removal effect.

[0030] Preferably, in the present invention, each dust removal device 2 is located directly above the inlet and outlet. In this way, it is better to ensure that the wind direction of the inlet and outlet is on the same side as the dust removal device 2, and it is better to ensure that the direction of the wind converges to the dust removal device 2, so as to facilitate better dust removal of the grain unloading warehouse 1. Of course, in the present invention, according to actual conditions and specific needs, each dust removal device 2 can also be set to other positions, which is not the only limitation here.

[0031] For further information, see Figure 1 and Figure 2 As shown, as a specific embodiment of the grain unloading depot dust removal system provided by the present invention, the dust removal device 2 is a pulse bag dust removal device, and the grain unloading depot 1 is provided with an air suction port 12. The dust removal device 2 is connected to the air suction port 12 through a pipe 4, and the air suction port 12 and the inlet and outlet are arranged on the same side of the grain unloading depot 1. In this way, by arranging a pulse bag dust removal device, the dust-containing gas enters the pulse bag dust removal device through the air suction port 12, and the dust particles fall into the ash hopper 21 of the pulse bag dust removal device 2 under the action of their own gravity for collection, and then as the dust-containing gas continues to move, when the dust-containing gas touches the filter bag of the pulse bag dust removal device, it is filtered through the filter bag, so that the dust is further filtered down, and better dust removal is achieved; the air suction port 12 is located on the same side as the inlet and outlet, which ensures that the wind direction of the inlet and outlet is consistent with the wind direction of the air suction port 12, and avoids the phenomenon of dust flying around during the dust removal process.

[0032] Preferably, a maintenance platform (not shown) is also provided on the grain unloading depot 1. In this way, when there is a problem with the dust removal device 2, the dust removal device 2 can be repaired through the maintenance platform, so that the dust removal device 2 can be inspected and repaired in real time, thereby improving the efficiency of maintenance.

[0033] Preferably, a muffler is also provided on the dust removal device 2 (not shown in the drawings). By providing the muffler on the dust removal device 2, the noise generated by the dust removal device 2 during the dust removal process can be absorbed, thereby reducing noise pollution.

[0034] For further information, see Figure 1 and Figure 2 As shown, as a specific embodiment of the grain unloading depot dust removal system provided by the present invention, the dust removal device 2 is arranged on the grain unloading depot 1 on the side close to the air suction port 12, and the grain unloading depot 1 is provided with a support platform, which can be used to support the dust removal device 2. In this way, by arranging the dust removal device 2 on the side close to the air suction port 12, the amount of the pipeline 4 can be reduced, the number of elbows in the pipeline 4 is reduced, and the dust collection effect is not affected due to the longer pipeline 4 and more bends.

[0035] For further information, see Figure 1 and Figure 2As shown, as a specific embodiment of the dust removal system of the grain unloading depot provided by the present invention, a sealing tile layer 5 is also provided in the grain unloading depot 1, and the sealing tile layer 5 is arranged corresponding to the position of the feeding port 11. In addition, a support column 6 is also provided in the grain unloading depot 1, and the support column 6 can be used to support the sealing tile layer 5. In this way, by arranging a layer of sealing tile layer 5 above the feeding port 11, the floating space of the dust is reduced, which is conducive to the centralized collection of the dust and improves the dust removal effect. Preferably, the vertical spacing between the feeding port 11 and the sealing tile layer 5 is 6m. In this way, by setting it to this height, it is ensured that the container vehicle 7 can pass freely, and the spacing between the feeding port 11 and the sealing tile layer 5 should not be too large, which is conducive to the centralized collection of dust in the later stage. Of course, in this embodiment, according to the actual situation and specific needs, the spacing between the feeding port 11 and the sealing tile layer 5 can also be other values, which is not limited here.

[0036] Preferably, the stopper 3 is an electric folding door. The electric folding door can quickly close the entrance and exit, which is efficient and convenient. Of course, in this embodiment, the stopper 3 can also be set as a baffle, etc., which is not limited here.

[0037] For further information, see Figure 3 As shown in the figure, as a specific embodiment of the grain unloading depot dust removal system provided by the present invention, the number of the dust removal devices 2 is three, and each dust removal device 2 is distributed at intervals on the grain unloading depot 1. In this way, by setting the number of dust removal devices 2 to three, on the one hand, the power of dust removal is increased and the absorption effect of dust removal is improved; on the other hand, when the overall volume of the grain unloading depot 1 is large, it is possible to realize the simultaneous unloading and dust removal of multiple container vehicles 7, thereby increasing the scope of use and avoiding waste of resources.

[0038] Preferably, the power of the three dust removal devices 2 is 22KW, 22KW, and 37KW respectively, and the total air volume generated by the two 22KW dust removal devices 2 is 20000m 3 / h, a 37KW dust removal device generates a total air volume of 40000m 3 / h, thus meeting the needs of larger grain unloading warehouses (space volume of about 2000m 3 ) air volume requirement. In this way, through the cooperation of three dust removal devices 2, the centralized collection efficiency of dust can reach 90%. After being processed by the three dust removal devices 2, the amount of particulate matter is 0.018kg / h (0.066t / a), and the emission concentration is 2.5mg / m 3 Of course, according to the actual situation and specific needs, the power of the three dust removal devices 2 can also be set to other values, which are not limited here.

[0039] In the present invention, the unloading warehouse 1 is set to a sealed state, thereby avoiding the adverse effects of natural wind on dust removal; multiple dust removal devices 2 are set on the same side of the inlet and outlet, thereby ensuring that the direction of the inlet and outlet wind is consistent with the direction of the dust removal device 2 wind, thereby avoiding turbulence of the gas in the unloading warehouse 1 during the dust removal process; a sealing tile layer 5 is set above the feeding port 11, thereby reducing the rising space of the dust, which is beneficial to the subsequent dust collection; by setting three dust removal devices 2, the centralized collection efficiency of the dust can be greatly improved, and the efficiency can reach more than 90%; through the above-mentioned multiple improvements, the dust removal effect of the unloading warehouse 1 is greatly improved.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
