Description

Technical Field

[0001] The utility model relates to the technical field of coal transportation, in particular to a dust suppression device for railway coal transportation. Background Art

[0002] Coal is a solid combustible mineral formed by the complex biochemical and physical-chemical changes of ancient plants buried underground, and is one of the commonly used main energy sources at present.

[0003] Coal is often transported to various regions by railway. During transportation, under the action of air flow and wind, coal powder will fly on the upper surface of the coal in the cargo box, which not only causes coal loss, but also causes environmental pollution. Therefore, it is often necessary to spray dust suppressant regularly.

[0004] At present, a dust suppression device is often used to spray the dust suppressant. The dust suppression device is usually installed near the track, and the number of spray holes on the spray rod is usually fixed. In order to make the dust suppressant fully sprayed on the coal, the length of the spray rod is much larger than the width of the conventional cargo box. When spraying a smaller cargo box, a large amount of dust suppressant will be sprayed outside the cargo box (not on the coal), resulting in excessive waste of the dust suppressant. Summary of the Utility Model

[0005] Therefore, the utility model provides a dust suppression device for railway coal transportation to solve the above problems in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] According to the first aspect of the utility model, a dust suppression device for railway coal transportation includes a hollow long rod. A first partition is fixedly connected to the inner sides of the two inner walls of the hollow long rod. A water pump is fixedly installed at the bottom end of the hollow long rod. Water pipes are connected to both the upper and lower ends of the water pump. The upper water pipe penetrates above the first partition. A plurality of liquid inlet holes are formed in the top surface of the first partition. A plurality of nozzles are fixedly connected to the bottom end of the hollow long rod. The number of nozzles is the same as the number of liquid inlet holes, and each nozzle is correspondingly located directly below each liquid inlet hole. A spraying length adjusting mechanism is provided below the first partition.

[0008] Further, the spraying length adjusting mechanism includes a pair of second partitions fixedly connected below the first partition. The bottom surface and the front and rear surfaces of the second partitions are fixedly connected to the inner wall of the hollow long rod. A left-right screw rod is rotatably connected between the two second partitions. Two sealing sliders are threadedly connected to the left-right screw rod. The sealing sliders are horizontally slidably connected to the front and rear inner walls of the hollow long rod. A motor is bolted to one side of one of the second partitions. The output end of the motor is fixedly connected to the left-right screw rod shaft.

[0009] Further, the lower water pipe is a flexible pipe, and a flange joint is fixedly connected to the bottom end of the water pipe.

[0010] Further, a column penetrating to the lower part thereof is provided on the top surface of the hollow long rod. The hollow long rod is slidably connected to the column up and down. A support plate is welded on the column. A pair of hydraulic cylinders are installed on the top surface of the support plate. The top output end of the hydraulic cylinder is fixed to the bottom end of the hollow long rod.

[0011] Further, a pair of guide rods are welded on the top surface of the support plate, a pair of fixing rods are welded on the top surface of the hollow long rod, a sliding sleeve slidably connected to the column up and down is sleeved on the column, the bottom of the sliding sleeve is fixedly connected to the top of the fixing rod, the sliding sleeve is slidably connected to the guide rod up and down, and a traction rope is fixedly connected between the sliding sleeve and the hollow long rod.

[0012] Further, windshields are bolted to the front and back of the hollow long rod, and the front and rear windshields are closely attached.

[0013] Further, a bracket is fixedly installed on the top surface of the hollow long rod. Two solar panels are installed on the top surface of the bracket. A storage battery electrically connected to the solar panel is fixedly installed at the bottom end of the bracket.

[0014] The utility model has the following advantages:

[0015] It can flexibly adjust the spraying range of the dust suppressant by the nozzle according to the width of the railway freight car. For example, when spraying the dust suppressant on a freight car with a relatively narrow width, the content of the dust suppressant spilled outside the freight car can be reduced, which can play a certain role in saving.

[0016] It can adjust the distance between the nozzle and the coal on the freight car, so that the nozzle and the coal are in a suitable height range.

Specific implementation manners

[0022] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0023] As Figures 1 to 4 shown, a dust suppression device for railway coal transportation in the first aspect embodiment of the present utility model includes a hollow long rod 10. A first partition 20 fixedly connected to the inner walls on both sides thereof is provided inside the hollow long rod 10. A water pump 30 is fixedly installed at the bottom end of the hollow long rod 10. Water pipes 40 are connected to both the upper and lower ends of the water pump 30. Among them, the upper water pipe 40 penetrates above the first partition 20. A plurality of liquid inlet holes 50 are formed on the top surface of the first partition 20. A plurality of spray heads 60 are fixedly connected to the bottom end of the hollow long rod 10. The number of the spray heads 60 is the same as that of the liquid inlet holes 50, and each spray head 60 is correspondingly located directly below each liquid inlet hole 50. A spraying length adjustment mechanism 70 is provided below the first partition 20. The spraying length adjustment mechanism 70 includes a pair of second partitions 71 fixedly connected below the first partition 20. The bottom surface and the front and rear surfaces of the second partition 71 are fixedly connected to the inner wall of the hollow long rod 10. A left and right screw rod 72 is rotatably connected between the two second partitions 71. Two sealing sliders 73 are threadedly connected to the left and right screw rod 72. The sealing sliders 73 are horizontally slidably connected to the front and rear inner walls of the hollow long rod 10. A motor 74 is bolted to one side of one of the second partitions 71. The output end of the motor 74 is fixedly connected to the shaft of the left and right screw rod 72.

[0024] In the above embodiments, it should be noted that the spacing between each nozzle 60 is the same, and the water output of the nozzle 60 is consistent with the water input of the liquid inlet hole 50, being in a balanced state. At the same time, the part where the output end of the motor 74 passes through the first partition 20 can adopt mechanical seal to avoid water leakage.

[0025] The technical effects achieved by the above embodiments are as follows: The spraying range of the dust suppressant by the nozzle 60 can be flexibly adjusted according to the width of the railway freight car. For example, when spraying the dust suppressant on a freight car with a relatively narrow width, the content of the dust suppressant spilled outside the freight car can be reduced, which can play a certain role in saving. At the same time, while adjusting the number of nozzles 60 opened, the number of liquid inlet holes 50 opened can also be adjusted, so that the spraying intensity difference of the nozzles 60 is relatively small and the spraying effect is good. Embodiment

[0026] As Figures 1 to 4 shown, a dust suppression device for transportation includes all the contents of Embodiment 1. In addition, the lower water pipe 40 is a flexible pipe, and a flange joint 80 is fixedly connected to the bottom end of the water pipe 40.

[0027] In the above embodiments, it should be noted that the upper water pipe 40 is made of stainless steel.

[0028] The technical effects achieved by the above embodiments are as follows: It can be fixedly connected to the water tank or the pipeline of the water tank, thus facilitating the water pumping of the water pump 30. Embodiment

[0029] As Figures 1 to 4 shown, a dust suppression device includes all the contents of Embodiment 2. In addition, a column 90 penetrating to its lower part is provided on the top surface of the hollow long rod 10. The hollow long rod 10 is slidably connected to the column 90 up and down. A support plate 100 is welded on the column 90. A pair of hydraulic cylinders 110 are installed on the top surface of the support plate 100. The top output end of the hydraulic cylinder 110 is fixed to the bottom end of the hollow long rod 10. A pair of guide rods 120 are welded on the top surface of the support plate 100. A pair of fixing rods 130 are welded on the top surface of the hollow long rod 10. A sliding sleeve 140 slidably connected to the column 90 up and down is sleeved on the column 90. The bottom of the sliding sleeve 140 is fixedly connected to the top of the fixing rod 130. The sliding sleeve 140 is slidably connected to the guide rod 120 up and down. A traction rope 150 is fixedly connected between the sliding sleeve 140 and the hollow long rod 10. Wind shields 160 are bolted on the front and back surfaces of the hollow long rod 10, and the front and rear wind shields 160 are closely attached.

[0030] In the above embodiments, it should be noted that the traction rope 150 is a steel wire rope and is wrapped with a rubber sleeve, having high strength and good corrosion resistance, which can play a good pulling role and greatly improve the stability of the hollow long rod 10.

[0031] The technical effects achieved by the above embodiments are as follows: It has the function of height adjustment, which can adjust the nozzle 60 and the coal to be within a suitable height range. Coupled with the wind shield 160, even in a windy environment, the dust suppressant can still be evenly sprayed on the coal, and the spraying effect is good. Embodiment

[0032] As Figures 1 to 4 Shown in the figure, a dust suppression device for railway coal transportation includes all the contents of Embodiment 3. In addition, a bracket 170 is fixedly installed on the top surface of the hollow long rod 10, two solar panels 180 are installed on the top surface of the bracket 170, and a storage battery 190 electrically connected to the solar panels 180 is fixedly installed at the bottom end of the bracket 170;

[0033] In the above embodiment, it should be noted that the solar panels 180 can convert light energy into direct current and store it in the storage battery 190. Then, the storage battery 190 can be converted into alternating current by means of an inverter carried by itself and supply power to the motor 74, the water pump 30, etc.;

[0034] The technical effects achieved by the above embodiments are as follows: When the entire dust suppression device for railway coal transportation is installed outdoors, it can be powered by solar energy, playing a role in saving resources.

[0035] Working principle: Start the motor 74 to drive the left and right screw rods 72 to rotate. If it rotates forward, the two sealing sliders 73 move closer to each other, and the number of nozzles 60 opened can be reduced. If it rotates backward, the two sealing sliders 73 move away from each other, and the number of nozzles 60 opened can be increased. Moreover, the number of liquid inlet holes 50 opened is the same as the number of nozzles 60 opened, which can be flexibly adjusted according to the width of the train freight carriages on the railway, reducing the waste of the dust suppressant (there is still some dust suppressant that is not sprayed on the coal). At the same time, by starting the hydraulic cylinder 110, the height of the hollow long rod 10 can be adjusted, and then the height of the nozzle 60 and the coal can be adjusted. Coupled with the wind shield 160, the interference of the wind on the dust suppressant can be reduced, and most of the dust suppressant can be sprayed on the coal.
