Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction equipment, in particular to a dust reduction spray device for a biomass fuel bin. Background Art

[0002] Biomass fuel silos usually include basic structures such as silo body, base, feed inlet, and discharge port, and are equipped with safety facilities such as smoke monitors and sprinklers. The smoke monitors are used to monitor the air conditions in the silo in real time to prevent the accumulation of harmful gases such as carbon monoxide, and the sprinklers are used to cool and humidify the biomass fuel when necessary to control its temperature and humidity and reduce the risk of fire.

[0003] Even after the biomass fuel in the silo is sprinkled with water, the biomass fuel itself has a relatively loose physical property and the particles are easily separated. Therefore, it is easy to break and scatter during the unloading process, thereby generating dust. Some silos will be equipped with a spray mechanism at the discharge port to achieve dust reduction during unloading. However, since most unloading operations can be separated from the opening of the spray mechanism, when unloading, the operator may fail to realize the need to open the spray mechanism simultaneously during unloading due to negligence or lack of familiarity with the operating procedures, thereby failing to achieve synchronized spray dust reduction operations during unloading. Utility Model Content

[0004] The purpose of the utility model is to provide a dust reduction spray device for a biomass fuel bin, which can effectively solve the problems in the background technology.

By means of the settings of the shunt pipe, the water inlet end, and the water outlet ends, the water flow can be divided into four spray heads.

[0010] As a further preferred embodiment of the present utility model, a sealing ring is fixedly installed on the outer side of the sealing valve core.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1-5 As shown, the utility model provides a dust reduction spray device for a biomass fuel bin, comprising a bin 1, a discharge hopper 2 and a dust reduction mechanism 3, the dust reduction mechanism 3 also comprising a first mounting rod 4, a second mounting rod 5 is fixedly mounted on one side of the first mounting rod 4, the second mounting rod 5 is fixedly mounted in the discharge hopper 2, a plurality of spray heads 6 are arranged on one side of the second mounting rod 5, the spray heads 6 are fixedly mounted on one side of the second mounting rod 5 through a first mounting seat 7, a diverter pipe 8 is fixedly mounted on the side of the first mounting rod 4 away from the second mounting rod 5, a sealing valve core 9 is movably mounted in the diverter pipe 8, and a grid plate 10 is also movably mounted between the diverter pipe 8 and the first mounting rod 4.

[0022] like Figures 2-3 As shown, a second mounting seat 11 is fixedly mounted on the upper end of the first mounting rod 4. With the arrangement of the second mounting seat 11, a rotational installation of the grid plate 10 can be achieved;

[0023] like Figure 2 , Figure 4As shown in the figure, one end of the shunt pipe 8 is fixedly installed with a water inlet end 12, and four water outlet ends 13 are also fixedly installed on the outer side of the shunt pipe 8. The water inlet end 12 is connected to the output end of an external delivery pump through a pipeline, and the water outlet ends 13 are connected to the input ends of corresponding spray heads 6 through pipelines. A first sealing groove 15 is formed in the shunt pipe 8, and a second sealing groove 16 is formed on one side in the first sealing groove 15. The shunt pipe 8 is fixedly installed on one side of the first mounting rod 4 through a bracket and keeps a certain distance from the first mounting rod 4. By means of the settings of the shunt pipe 8, the water inlet end 12 and the water outlet ends 13, the water flow can be divided into four spray heads 6;

[0024] As Figures 2-5 shown in the figure, a sealing ring 17 is fixedly installed on the outer side of the sealing valve core 9. A limiting block 18 is arranged at one end of the sealing valve core 9. A screw rod 19 is fixedly installed through the center position in the limiting block 18. One end of the screw rod 19 is threadedly connected to one end of the sealing valve core 9. The other end of the screw rod 19 passes through a through hole in the first mounting rod 4 and is limited by a nut. The sealing valve core 9 is inserted and installed in the first sealing groove 15. A compression spring 20 is sleeved on the screw rod 19 between the limiting block 18 and the first mounting rod 4. Two connecting rods 14 are fixedly installed at the upper end of the grid plate 10. The two connecting rods 14 are pivotally connected in the second mounting seat 11. And the sealing valve core 9 between the sealing valve core 9 and the limiting block 18 is placed between the two connecting rods 14. By means of the settings of the grid plate 10 and the connecting rods 14, and in cooperation with the limiting block 18, the screw rod 19 and the compression spring 20, when the material is unloaded from the unloading hopper 2, the pushing force of the fuel during unloading can be used to push the grid plate 10 to rotate around the connecting rods 14 as the axis, so as to drive the screw rod 19 to move in cooperation with the limiting block 18, and then the water inlet end 12, the first sealing groove 15 and the cavities of the multiple water outlet ends 13 can be communicated, thus realizing automatic spray dust reduction during feeding.

[0025] It should be noted that the present utility model is a dust reduction spray device for a biomass fuel bin. When the biomass fuel in the bin 1 is unloaded through the unloading hopper 2, since the biomass fuel in the bin 1 will slide down through the unloading hopper 2, therefore, the pushing force of the fuel unloading can be used to push the lower end of the grid plate 10. Then, the grid plate 10 rotates in the second mounting seat 11 with the two connecting rods 14 at the upper end as the axis, and further makes the two connecting rods 14 synchronously push the limiting block 18 to one side. Then, the limiting block 18 drives the two ends of the screw rod 19 to move in the first mounting rod 4 and the first sealing groove 15 respectively, and makes the limiting block 18 compress the compression spring 20 towards the first mounting rod 4 side. Then, the screw rod 19 drives the sealing valve core 9 to move in the first sealing groove 15. Further, after the sealing valve core 9 moves in the first sealing groove 15, the cavity between the water inlet end 12, the first sealing groove 15 and the four water outlet ends 13 is communicated. Further, the externally supplied dust reduction water is divided into the four spray heads 6 through the four water outlet ends 13 and the pipelines, and then the fuel in the unloading hopper 2 is spray-dusted through the four spray heads 6;

[0026] After the discharging is completed and the grid plate 10 is no longer subjected to the thrust of the fuel, its compression spring 20 extends and rebounds, thereby pushing the limit block 18 to move back to its original position. Then, the limit block 18 synchronously drives the screw rod 19 and the connecting rod 14 to return to their original positions. At the same time, the screw rod 19 also drives the sealing valve core 9 to return to its original position, so that one end of the sealing valve core 9 abuts against the inner side of the first sealing groove 15, thereby closing the cavity between the water inlet end 12 and the first sealing groove 15. Thus, after the discharging hopper 2 finishes discharging, the spraying operation of the spray head 6 is automatically stopped.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
