[0023] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0024] A heating device for a fracturing proppant rotary kiln comprises a smoke chamber 1, a spray gun 2 is connected to one side surface of the smoke chamber 1, a controller 3 is installed at one end of the top of the spray gun 2, an air inlet pipe 4 is connected to one end of the spray gun 2, an electric control valve 5 is sleeved and installed on the outer ring surface of the air inlet pipe 4, a flame-spraying pipe 6 is connected to one end of the spray gun 2 located inside the smoke chamber 1, a plurality of nozzles 7 are evenly installed at the top and both sides of the flame-spraying pipe 6, a temperature sensor 8 is installed at one end of the top of the flame-spraying pipe 6, a connecting sleeve 9 is fixedly connected to one end of the flame-spraying pipe 6, a sealing ring plug 10 is connected to one end of the connecting sleeve 9, and a tooth groove 11 is provided on the length square of the top of the flame-spraying pipe 6;

[0025] A fixing seat 12 is fixedly installed on the top of the outer side surface of the smoke chamber 1, and a forward and reverse motor 13 is installed on the top of the fixing seat 12. A protective sleeve 14 is connected between one end of the forward and reverse motor 13 and the outer side surface of the smoke chamber 1. A rotating shaft 15 is installed inside the protective sleeve 14, and a gear 16 is installed on one end of the rotating shaft 15.

[0026] For example, please refer to Figure 1 , Figure 2 and Figure 3 The interior of the nozzle 2 is communicated with the interior of the air inlet pipe 4, and one end of the interior of the nozzle 2 is sealed and connected to the smoke chamber 1. One end of the nozzle 2 is sleeved with the connecting sleeve 9 on the flame spraying pipe 6 in the smoke chamber 1, and the sealing ring plug 10 can slide on the inner wall of the spray gun 2. The gas enters the interior of the spray gun 2 from the air inlet pipe 4, and then enters the interior of the flame spraying pipe 6. The burning flame is sprayed through the nozzle 7 on the flame spraying pipe 6 to heat the inside of the cylinder of the rotary kiln. The controller 3 is connected to the electric control valve 5 and the temperature sensor 8. The controller 3 is electrically connected, and a display screen is provided on the controller 3, and the display screen can display the real-time temperature monitored by the temperature sensor 8. The heating temperature is set. When the temperature sensor 8 monitors that the internal temperature of the rotary kiln barrel remains consistent with the set value for a long period of time, the opening and closing angle of the electric control valve 5 remains unchanged. If cooling is required, the opening and closing angle of the electric control valve 5 can be reduced. At this time, the air intake is reduced, and the heating flame is reduced, thereby achieving a cooling effect. On the contrary, the combustion temperature can be increased to continuously heat the inside of the rotary kiln barrel.

[0027] For example, please refer to Figure 1 , Figure 2 and Figure 3, the protective sleeve 14 is connected between the outer side of the smoke chamber 1 and one end of the forward and reverse motor 13, and one end of the rotating shaft 15 is connected to the output end of the forward and reverse motor 13, the rotating shaft 15 does not touch the inner wall of the protective sleeve 14, and one end of the rotating shaft 15 extends to the inside of the smoke chamber 1. When the forward and reverse motor 13 is started, the rotating shaft 15 can be driven to rotate inside the protective sleeve 14 and the inside of the smoke chamber 1. The gear 16 is located below one end of the flame-spraying tube 6, and the gear 16 and the tooth groove 11 at the bottom of the flame-spraying tube 6 are meshed with each other. The connection between the flame-spraying tube 6 and the smoke chamber 1 is a sliding connection. When the rotating shaft 15 rotates, the gear 16 drives the tooth groove 11 to move, so that one end of the flame-spraying tube 6 moves toward the inside of the cylinder of the rotary kiln;

[0028] The length of the connecting sleeve 9 is the same as that of the flame-spraying tube 6, and the interior of the connecting sleeve 9 is communicated with the interior of the flame-spraying tube 6. When the connecting sleeve 9 slides to the maximum distance toward one end of the spray gun 2, the sealing ring plug 10 will be blocked by the edge of one end of the spray gun 2, and the flame-spraying tube 6 can extend into the interior of the barrel of the rotary kiln. The flame-spraying tubes 6 at both ends of the barrel of the rotary kiln extend into the interior of the barrel of the rotary kiln, and can be heated in most of the internal space of the barrel of the rotary kiln, thereby quickly heating the interior of the barrel of the rotary kiln.

[0029] The working process of the utility model: using the heating device of the fracturing proppant rotary kiln designed by the present invention, when heating the inside of the fracturing proppant rotary kiln, first open the electric control valve 5, so that the gas enters the inside of the spray gun 2 from the air inlet pipe 4, and then enters the inside of the flame-spraying pipe 6, and the burning flame is sprayed through the nozzle 7 on the flame-spraying pipe 6 to heat the inside of the cylinder of the rotary kiln. When heating, the heating temperature inside the rotary kiln is set. When the temperature sensor 8 detects that the temperature inside the cylinder of the rotary kiln remains consistent with the set value for a long period of time, the opening and closing angle of the electric control valve 5 remains unchanged. If cooling is required, the opening and closing angle of the electric control valve 5 can be reduced. At this time, the air intake is reduced, and the burning flame is reduced. , thereby achieving the effect of cooling down, on the contrary, the combustion temperature can be increased to continuously heat the inside of the cylinder of the rotary kiln. In addition, when the forward and reverse motors 13 are started, the rotating shaft 15 can be driven to rotate inside the protective sleeve 14 and the smoke chamber 1. When the rotating shaft 15 rotates, the gear 16 drives the tooth groove 11 to move, so that one end of the flame-spraying pipe 6 moves toward the inside of the cylinder of the rotary kiln. At this time, the flame-spraying pipe 6 can extend toward the inside of the cylinder of the rotary kiln. The flame-spraying pipes 6 at both ends of the cylinder of the rotary kiln extend toward the inside of the cylinder of the rotary kiln, and can be heated in most of the internal space of the cylinder of the rotary kiln, quickly heating the inside of the cylinder of the rotary kiln, reducing the heating time, reducing fuel loss, and reducing the use cost.

[0030] In summary, the device can extend the heating area of ​​the fracturing proppant rotary kiln to the deep inside of the rotary kiln cylinder, increase the heating space, and thus quickly heat the inside of the rotary kiln cylinder, reduce the heating time, reduce fuel loss, and reduce the use cost.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
