Description

Technical Field

[0001] The utility model relates to the technical field of dust suppressant spraying equipment, in particular to dust suppressant spraying equipment for coal transport trains. Background Art

[0002] Dust suppressants are composed of a new type of multifunctional high molecular polymer. The cross-linked molecules in the polymer form a network structure, and there are various ion groups between the molecules. Due to the high charge density, it has a strong affinity with the ions, and can quickly capture and firmly adsorb particulate dust through coagulation and adhesion. After drying, it can solidify into a film on the dust surface, so it has a strong dust suppression and dust prevention effect.

[0003] Coal transportation is mostly done by rail and road, and trains and trucks are often uncovered. During transportation, the relative movement of airflow and wind causes a large amount of coal dust to fly, which not only causes coal loss but also dust pollution. Therefore, during the actual transportation of coal, a mixture of dust suppressant and water is sprayed on the coal piles of the transport vehicles through spraying equipment to prevent coal dust from polluting the environment and reducing coal loss.

[0004] Gantry spraying equipment is one of the commonly used dust suppressant spraying devices in existing railway coal transportation. When the coal train passes under the gantry, the spraying device is operated to spray dust suppressant. The operation is simple and the work is efficient. However, the spraying device is always exposed to the outside air. When encountering a low temperature environment, the residual liquid in the nozzle is easily frozen, and the nozzle is frozen, affecting normal operation. Based on this, a dust suppressant spraying equipment for coal trains is provided. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 4In an embodiment of the present invention, a dust suppressant spraying device for a coal transport train includes a support body 1, which is composed of a gantry 101, a rotating silo 102, and a transmission silo 104. The rotating silo 102 and the transmission silo 104 are located at the bottom of the lateral portion of the gantry 101, and the transmission silo 104 is located at one end of the arc-shaped groove 103.

[0031] The rotating silo 102 and the transmission silo 104 are provided with a spraying assembly 2, which is used for spraying dust suppressant.

[0032] The spraying assembly 2 includes a spraying unit and an antifreeze turning unit;

[0033] The antifreeze flip unit is used to realize the flipping operation of the spray unit. The spray unit flips downward for spraying dust suppressant. The spray unit flips upward and is completely stored inside the rotating silo 102 for antifreeze protection.

[0034] The spray unit includes a spray pipe 201, a spray head 202, an external connecting pipe 204, and a rotating shaft 205;

[0035] There are multiple nozzles 202, and multiple spray pipes 201 are evenly distributed and fixed on the outer top of the spray pipe 201. The external connecting pipe 204 is rotatably connected to one end of the spray pipe 201 and is in communication with the inner cavity of the spray pipe 201. The end of the external connecting pipe 204 away from the spray pipe 201 passes through one end of the horizontal part of the gantry 101 and is in communication with the output end of the external pump body;

[0036] The rotating shaft 205 is fixed to the other end of the spray pipe 201 and is rotatably connected to the inner wall end surface of the rotating silo 102;

[0037] The upwardly distributed nozzles 202 are housed inside the rotating silo 102 to separate the air from the outside environment, thereby achieving an anti-freeze effect.

[0038] The spray pipe 201 rotates the nozzle 202 to face downwards to spray the dust suppressant;

[0039] The antifreeze turning unit includes a fan-shaped heat-insulating sealing block 203, a driven gear 206, a driving motor 207, and a driving gear 208;

[0040] The fan-shaped heat-insulating sealing block 203 is wrapped around the outside of the spray pipe 201 and is symmetrically distributed with the nozzle 202. When the nozzle 202 is distributed upward, the fan-shaped heat-insulating sealing block 203 blocks the bottom opening of the rotating silo 102, thereby achieving the effect of sealing the inner cavity of the rotating silo 102;

[0041] The driven gear 206 is located inside the transmission compartment 104 and is fixedly connected to one end of the rotating shaft 205. The driving motor 207 is fixed to the vertical end surface of the gantry 101. The driving gear 208 is fixed to the output end of the driving motor 207 and extends into the transmission compartment 104 to mesh with the driven gear 206.

[0042] When the driving motor 207 is in operation, the driving gear 208 , the driven gear 206 , and the rotating shaft 205 are used to transmit the synchronous rotation of the spray pipe 201 , the nozzle 202 , and the fan-shaped heat-insulating sealing block 203 .

[0043] In this embodiment, when the dust suppressant spraying device is in use and spraying is not required, the nozzles 202 are stored in the rotating silo 102 in an upwardly distributed manner, and the fan-shaped heat-insulating sealing block 203 forms a seal on the bottom opening of the rotating silo 102. The fan-shaped heat-insulating sealing block 203 has a heat-insulating effect, so that external cold air does not enter the rotating silo 102, thereby achieving the effect of antifreeze protection for the nozzles 202 and the spray pipe 201 (it should be supplemented that the external connecting pipe 204 is wrapped with antifreeze insulation material, such as rubber insulation pipe, to ensure that the liquid inside the external connecting pipe 204 does not freeze);

[0044] When it is necessary to spray the dust-removing agent, the drive motor 207 is started, the drive motor 207 drives the driving gear 208 to rotate, the driving gear 208 drives the driven gear 206 to rotate, the driven gear 206 drives the spray pipe 201 to rotate through the rotating shaft 205, and the spray pipe 201 drives the nozzle 202 and the fan-shaped heat-insulating sealing block 203 to flip, and finally the nozzle 202 is vertically downward, and the fan-shaped heat-insulating sealing block 203 is stored in the rotating silo 102. Then, the external pump body is started to transport the dust-removing agent to the nozzle 202 for spraying;

[0045] After the spraying operation is completed, the driving motor 207 is started again to rotate the nozzle 202 to an upward state to avoid being exposed to the outside and freezing.

[0046] Please refer to Figures 1 to 3 An arc-shaped groove 103 is provided on the top of the inner wall of the rotating silo 102. An electric heating tube 4 is installed inside the arc-shaped groove 103. When the electric heating tube 4 is in operation, it is used to heat the spray pipe 201 and the nozzle 202 in the inner space of the rotating silo 102.

[0047] A solar panel 3 is installed on the top of the horizontal part of the gantry 101. The solar panel 3 converts solar energy into electrical energy, which is used to provide power for the operation of the solar panel 3 and the drive motor 207.

[0048] In this embodiment, while the rotating silo 102 shields and protects the spray pipe 101 and the nozzle 102, the electric heating tube 4 can be used to heat the interior of the rotating silo 102, thereby maintaining a certain constant temperature of the rotating silo 102, further improving the antifreeze effect.

[0049] It should be noted that a temperature sensor is also installed on the inside of the arc-shaped groove 103 to achieve temperature control. In addition, a control cabinet is also installed on the outside of the vertical part of the gantry 101. The control cabinet is equipped with a corresponding controller and a battery. The battery is used to store the electrical energy converted by the solar panel 3, and the controller is used to control the operation of the drive motor 207 and the electric heating tube 4.

[0050] Please refer to Figures 1 to 3 The outer side of the fan-shaped thermal insulation blocking block 203 matches the inner diameter of the rotating silo 102, and the inner diameter of the electric heating tube 4 is smaller than the outer diameter of the fan-shaped thermal insulation blocking block 203, and the fan angle of the fan-shaped thermal insulation blocking block 203 is greater than one hundred and eighty degrees.

[0051] In this embodiment: this structure can ensure that the electric heating tube 4 does not affect the rotation of the fan-shaped heat-insulating blocking block 203;

[0052] The fan-shaped heat-insulating sealing block 203 has a fan-shaped angle greater than one hundred and eighty degrees, thereby ensuring a good sealing effect of the fan-shaped heat-insulating sealing block 203 on the rotating silo 102 .

[0053] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
