[0002] The coal preparation and transfer station is an important link connecting different belt conveyors. It is used to transport coal from the stockyard through belts, transfer stations and pre-crushers to the coal storage silo, and then automatically blend coal according to the needs of coking. Finally, the blended clean coal is transported to the coal tower for storage, ready to be used for coal charging operations in the coke oven at any time.

[0003] The utility model patent with authorization announcement number CN216272108U provides a dry fog dust suppression system for a coal conveying transfer station, which relates to the field of coal mine dust suppression technology. It includes a dry fog generating device and a spraying device assembly. The dry fog generating device is connected to the spraying device assembly. There are multiple spraying device assemblies. Each spraying device assembly includes a housing and a sprayer. The sprayer is installed on the housing.

[0004] The dry fog dust suppression system proposed in the above patent is a fixed design, which limits the dust suppression range and makes it difficult to effectively and comprehensively suppress dust in the internal area of ​​the coal transfer station. In order to overcome the shortcomings of the above technology, we propose a dry fog dust suppression device for coal transfer stations. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dry fog dust suppression device for coal preparation and transfer stations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dry fog dust suppression device for a coal preparation and transfer station includes a truss track on which a dry fog dust suppression component is mounted. The dry fog dust suppression component includes a housing, a water tank fixedly mounted on the upper side of the housing, a water inlet bend connected to the upper side of the water tank, a second solenoid valve fixedly mounted at the port of the water inlet bend, a high-pressure water pump and a column fixedly mounted at the bottom of the housing, an atomizing nozzle fixedly mounted at the lower end of the column, a first connecting pipe connecting the high-pressure water pump and the water tank, a second connecting pipe connecting the atomizing nozzle and the high-pressure water pump, and a water supply pipe located at the right end of the truss track, with the first solenoid valve mounted at the lower end of the water supply pipe.

[0008] Furthermore, the chassis is equipped with a drive assembly and a sensing assembly.

[0009] Furthermore, the drive assembly includes a drive shaft and a driven shaft, both of which rotate through the housing. Rollers are fixedly installed at both ends of the drive shaft and the driven shaft, and annular grooves are formed on the rollers.

[0010] Furthermore, a large gear is fixedly mounted on the drive shaft, and a built-in motor is provided on the side of the large gear.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-6 A dry fog dust suppression device for a coal preparation and transfer station includes a truss track 1, on which a dry fog dust suppression component 4 is installed. The dry fog dust suppression component 4 includes a housing 41, on which a water tank 43 is fixedly installed. A water inlet bend 44 is connected to the upper side of the water tank 43. A second solenoid valve 45 is fixedly installed at the port of the water inlet bend 44. A high-pressure water pump 47 and a column 48 are fixedly installed at the bottom of the housing 41. An atomizing nozzle 49 is fixedly installed at the lower end of the column 48. A first connecting pipe 46 is connected between the high-pressure water pump 47 and the water tank 43. A second connecting pipe 410 is connected between the atomizing nozzle 49 and the high-pressure water pump 47. A water supply pipe 2 is provided at the right end of the truss track 1. A first solenoid valve 3 is installed at the lower end of the water supply pipe 2. A drive component 5 and a sensing component 6 are provided on the housing 41.

[0025] In this configuration, the truss track 1 includes an upper crossbeam 11 and a lower crossbeam 12. Several struts 13 are fixedly connected between the upper crossbeam 11 and the lower crossbeam 12. Mounting plates 14 are symmetrically fixedly connected to both ends of the upper crossbeam 11 and the lower crossbeam 12. The mounting plates 14 are provided with screw positioning holes.

[0026] With the above configuration, the truss track 1 is composed of an upper crossbeam 11, a lower crossbeam 12, and a strut 13, which has a large bending resistance and thus can provide strong load-bearing capacity, providing stable support for the dry fog dust suppression component 4.

[0027] In this configuration, the drive assembly 5 includes a drive shaft 51 and a driven shaft 52, both of which rotate through the housing 41. Rollers 53 are fixedly mounted at both ends of the drive shaft 51 and the driven shaft 52. Annular grooves 54 are provided on the rollers 53. A large gear 55 is fixedly mounted on the drive shaft 51. An internal motor 56 is provided on the side of the large gear 55. The internal motor 56 is fixedly mounted inside the housing 41, and a small gear 57 is fixedly mounted on the output end of the internal motor 56. The small gear 57 meshes with the large gear 55, and the annular groove 54 engages with the upper crossbeam 11.

[0028] With the above configuration, the built-in motor 56 can drive the pinion 57 to rotate. The pinion 57 meshes with the large gear 55, thereby synchronously driving the drive shaft 51 to rotate. This causes the rollers 53 at both ends of the drive shaft 51 to rotate synchronously, which in turn causes the rollers 53 to roll on the upper side of the upper crossbeam 11, driving the entire dry fog dust suppression assembly 4 to move on the upper side of the upper crossbeam 11. The driven shaft 52 and the rollers 53 at both ends follow the rotation.

[0029] In this method, the sensing component 6 includes a pressure sensor 61. Two pressure sensors 61 are symmetrically fixedly installed on the side wall of the chassis 41. A telescopic rod 62 is fixedly installed on the side of the pressure sensor 61. A contact plate 64 is fixedly installed on the outer end of the telescopic rod 62. A spring 63 is fixedly connected between the pressure sensor 61 and the contact plate 64. A controller 42 is fixedly installed on the side of the chassis 41.

[0030] With the above-described configuration, when the contact plate 64 comes into contact with the factory wall fixed to the side of the dry fog dust suppression component 4, the spring 63 will transmit contact pressure to the pressure sensor 61, and the pressure sensor 61 will sense the pressure signal. At this time, the controller 42 controls the built-in motor 56 to stop driving, so as to prevent the chassis 41 from hitting the factory wall. In addition, this stop position on the right side corresponds to the end of the water supply pipe 2 above. When water needs to be added to the water tank 43, the controller 42 controls the first solenoid valve 3 and the second solenoid valve 45 to open simultaneously. At this time, the water flowing out from the water supply pipe 2 flows down to the upper port of the water inlet bend 44, realizing the automatic water filling of the water tank 43.

[0031] The working principle of the dry fog dust suppression device for a coal preparation and transfer station provided by this utility model is as follows:

[0032] In use, the truss track 1 is laid and installed inside the factory building of the dedicated transfer station, and the dry fog dust suppression component 4 is placed on the upper side of the truss track 1, so that the annular groove 54 opened on the inner side of the roller 53 engages with the upper crossbeam 11. At the same time, a water supply pipe 2 is installed at the end of the truss track 1, so that the lower end of the water supply pipe 2 is aligned with the upper port of the upper water inlet bend 44 of the dry fog dust suppression component 4 when it stops at the end of the truss track 1. During daily use, the built-in motor 56 drives the roller 53 to rotate, causing the housing 41 to slide on the upper side of the truss track 1, and the high-pressure water pump 47 is turned on at the same time. The high-pressure water pump 47 draws water from the inside of the water tank 43 through the first connecting pipe 46 and delivers it to the atomizing nozzle 49 through the second connecting pipe 410. The atomizing nozzle 49 atomizes the water into fine droplets, forming a mist that is sprayed out. When these tiny water droplets encounter dust particles in the air, they are more likely to collide and adhere to the dust particles because they are similar in size. The water droplets will adhere to the dust particles, making them heavier and gradually agglomerating into larger particles. As the dust particles continue to grow larger, they will gradually settle to the ground under the action of gravity, thereby achieving the effect of dust suppression.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
