Description

Technical Field

[0001] The utility model relates to an ice melting device, in particular to an ice melting device for a spiral barrel of a waste coal processing machine. Background Art

[0002] At present, all coal chemical plants and power plants will sample and analyze the purchased commercial coal before transporting it to the plant silo. The raw coal sampling generally uses a bridge-type fully automatic sampling machine to sample the raw coal carried by cars and trains multiple times. The raw coal sampling uses a spiral drill barrel to drill into the raw coal in the carriage of the transport vehicle to a certain depth, and the sampled coal is transported to the raw coal processing process of the raw coal adopting machine with the help of the sampling spiral. After the raw coal is sampled, the remaining raw coal is transported to the raw coal transport vehicle by the abandoned coal processing machine, and then transported to the raw coal storage by the vehicle.

[0003] Because the raw coal contains moisture during transportation, in the cold winter weather, the spiral barrel of the waste coal processing machine will be frozen due to the accumulation of coal samples, which will cause the sampling spiral inside to get stuck and cannot work normally. It is necessary to manually knock and break it or use steam to melt the ice and clean the frozen coal samples in the spiral barrel to ensure the normal operation of the raw coal sampling machine. Manual cleaning of frozen coal samples is labor-intensive and may cause mechanical injuries to operators. Utility Model Content

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0039] See also Figure 1 to Figure 6 As an embodiment of the utility model, the ice melting device of the spiral barrel of the waste coal treatment machine includes a spiral barrel frame 1 and a hopper 12 fixedly mounted on the spiral barrel frame 1;

[0040] The spiral barrel frame 1 is provided with a blast assembly, and the blast assembly can blow air into the hopper 12;

[0041] The spiral barrel frame 1 is also provided with a pressurizing component, which cooperates with the blasting component. The pressurizing component can deliver high-pressure gas to the blasting component when the blasting component is in action, so as to increase the wind pressure of the blasting component blowing air into the hopper 12;

[0042] A heating cylinder 11 cooperating with the blast assembly and the pressurizing assembly is fixedly mounted on the spiral barrel frame 1 . The heating cylinder 11 can heat the gas delivered to the blast assembly to increase the air temperature of the air blown by the blast assembly into the hopper 12 .

[0043] In this embodiment, abandoned coal is thrown into the spiral barrel through the hopper 12. Since the abandoned coal is placed outdoors for a long time, it will freeze solid in cold weather, affecting the transportation and reuse of the abandoned coal.

[0044] When the frozen abandoned coal is put into the hopper 12, the air is pressurized by the pressurizing component and the high-pressure gas is delivered to the blast component. The high-pressure gas will be heated by the heating cylinder 11 when passing through the heating cylinder 11, so the gas reaching the blast component becomes high-pressure and high-temperature gas, which is delivered to the hopper 12 by the blast component. The high-pressure and high-temperature gas is used to accelerate the air flow rate on the surface of the frozen abandoned coal and increase the temperature of the abandoned coal, so as to accelerate the melting of ice on the surface of the abandoned coal and accelerate the evaporation of water formed after the ice melts.

[0045] Through the cooperation between the pressurizing component, the blast component and the heating cylinder 11, the physical method of increasing the surface flow rate of the abandoned coal and raising the temperature is used to accelerate the melting of ice and the evaporation of water, so that the abandoned coal can be smoothly transported to the processing station after entering the spiral barrel from the hopper 12, and the moisture content of the abandoned coal transported to the processing station meets the reuse requirements, thereby avoiding the reduction of the content of available components in the abandoned coal during reuse.

[0046] As a further solution of the utility model, a motor 2 is fixedly mounted on the spiral barrel frame 1, a rotating shaft 3 is fixedly mounted on the output end of the motor 2, and the rotating shaft 3 is connected to the pressurizing assembly and the blowing assembly.

[0047] In this embodiment, when the waste coal put into the hopper 12 is frozen, the motor 2 is started in real time. When the motor 2 is operated, it will drive the rotating shaft 3 to rotate. The rotating rotating shaft 3 drives the pressurizing component and the blowing component connected to the rotating shaft 3 to operate, so as to accelerate the melting of ice on the waste coal and the evaporation of water.

[0048] As a further solution of the utility model, the blowing assembly includes a blower 10 fixedly mounted on the spiral barrel frame 1, and a large pulley 9 is fixedly mounted on the rotating shaft of the blower 10; a small pulley 8 is fixedly mounted on the rotating shaft 3, and the large pulley 9 and the small pulley 8 are connected by a belt.

[0049] In this embodiment, when the rotating shaft 3 rotates, the small pulley 8 is driven to rotate, and the small pulley 8 rotates through the large pulley 9, thereby driving the rotating shaft of the blower 10 to rotate, so that the blower 10 can blow air into the hopper 12. Blowing air into the hopper 12 by the blower 10 can speed up the air flow rate on the surface of the waste coal, thereby accelerating the melting of ice.

[0050] As a further solution of the utility model, the blowing assembly also includes a blowing duct 1001 fixedly installed on the air outlet of the blower 10; an air inlet 1201 is fixedly installed on the side of the hopper 12 close to the blower 10, and the end of the blowing duct 1001 away from the blower 10 is fixedly installed on the air inlet 1201.

[0051] In this embodiment, when the blower 10 is in operation, the air blown by the blower 10 is discharged from the air outlet, flows into the air inlet 1201 through the air blast pipe 1001, and blows onto the waste coal in the hopper 12 through the air inlet 1201 to accelerate the air flow rate on the surface of the waste coal, so as to accelerate the melting of ice on the surface of the waste coal.

[0052] The air inlet 1201 is tilted upward to prevent excessive discarded coal from being put into the hopper 12, so that the discarded coal enters the blast duct 1001 through the air inlet 1201, thereby blocking the blast duct 1001 and affecting the efficiency of the blast assembly in blowing air into the hopper 12.

[0053] As a further solution of the utility model, the pressurizing assembly includes a first pulley 4 fixedly mounted on the rotating shaft 3; a piston cylinder 7 is fixedly mounted on the spiral barrel frame 1, and a second pulley 5 is rotatably mounted on the piston cylinder 7, and the first pulley 4 and the second pulley 5 are connected by a belt.

[0054] The pressurizing assembly also includes a piston rod 6 that is slidably engaged in the piston cylinder 7, and a piston 601 is fixedly installed at one end of the piston rod 6 located inside the piston cylinder 7, and the piston 601 is slidably engaged with the piston cylinder 7; a connecting rod 13 is rotatably installed at one end of the piston rod 6 away from the piston 601; a raised column is fixedly provided on the second pulley 5, and the connecting rod 13 is rotatably installed on the raised column at one end away from the piston rod 6.

[0055] In this embodiment, when the rotating shaft 3 rotates, it will drive the first pulley 4 to rotate, and the first pulley 4 will drive the second pulley 5 to rotate through the belt. The rotating second pulley 5 will drive the piston rod 6 to slide upward or downward along the length direction of the piston cylinder 7 through the connecting rod 13, so as to drive the piston 601 to slide upward or downward in the piston cylinder 7. When the piston 601 slides downward, it will compress the air in the piston cylinder 7, thereby increasing the air pressure output to the air blowing assembly; when the piston 601 slides upward, it will suck the air outside the piston cylinder 7 into the piston cylinder 7, so that the pressurizing assembly can continuously deliver high-pressure gas to the air blowing assembly. The high-pressure gas is used to increase the wind speed of the blower 10, and further increase the air flow rate on the surface of the abandoned coal.

[0056] Since the first pulley 4 and the second pulley 5 have the same size, and the small pulley 8 is half the size of the large pulley 9, the blowing assembly is also in action when the pressurizing assembly is pressurizing and sucking air, so that the entire device can continuously accelerate the melting of ice.

[0057] As a further solution of the utility model, an air inlet valve 14 and an air outlet valve 15 are fixedly installed on the piston cylinder 7. The air outlet valve 15 is connected to the air inlet of the heating cylinder 11 through a conduit, and the air outlet of the heating cylinder 11 is connected to the air inlet of the blower 10 through a conduit.

[0058] In this embodiment, both the air inlet valve 14 and the air outlet valve 15 are one-way valves, so that when the pressurizing component delivers high-pressure gas to the blowing sub-component, there will be no leakage from the air inlet valve 14, thereby ensuring the efficiency of the device in melting ice cubes; and when the pressurizing component inhales air into the piston cylinder 7, the gas in the blowing component will not be sucked back into the piston cylinder 7.

[0059] When the air pressurized by the pressurizing assembly flows into the heating cylinder 11, it is heated. Then, the high-temperature and high-pressure gas flows into the blast assembly from the gas outlet of the heating cylinder 11, so that the blast assembly blows out the high-temperature and high-pressure gas to accelerate the melting of ice on the abandoned coal.

[0060] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
