Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for oil extraction, and in particular, it is a drying equipment for semi-finished oil fracturing proppant. Background Technology

[0002] In oil extraction, fracturing proppant plays a crucial role, supporting fractures during fracturing operations and allowing oil to flow more smoothly. During production, the semi-finished product of fracturing proppant often contains a certain amount of moisture, requiring drying. Traditional drying equipment for semi-finished fracturing proppant can meet basic drying requirements; however, the semi-finished product may clump together, has weak dispersing ability, and the moisture inside the clumps is difficult to evaporate. Hot air can only contact the surface of the clumps, causing the drying process to concentrate on the surface, resulting in prolonged overall drying time and significantly reduced efficiency.

[0003] A search revealed Chinese patent documents (authorization announcement number CN221881999U). This utility model relates to the field of proppant semi-finished product drying technology, specifically to a drying device for semi-finished petroleum fracturing proppant. The device includes a fixed base, a drying body, a feed inlet, and a feeding assembly. The drying body is installed on the fixed base and dries the fracturing proppant. The feed inlet is installed on the drying body. The feeding assembly includes a storage tank, a conveying pipe, spiral blades, a drive component, and a feeding trough. The storage tank is fixedly connected to the fixed base. This reduces the frequency of adding proppant to the drying body, thus saving significant manpower. While the device can meet basic drying requirements, the semi-finished petroleum fracturing proppant may clump, has weak dispersing ability, and the moisture inside the clumps is difficult to evaporate. Hot air can only contact the surface of the clumps, causing the drying process to mainly concentrate on the surface of the clumps, resulting in a prolonged overall drying time and significantly reduced efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for semi-finished petroleum fracturing proppant to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for semi-finished petroleum fracturing proppant, comprising a drying drum for preventing raw material leakage during the drying process. Two fixed plates are welded to the vertical inner wall of the drying drum. A fan-shaped hollow column is welded to the side of each of the two fixed plates. A spring is connected inside the fan-shaped hollow column. A fan-shaped moving plate is connected to the end of the spring away from the fixed plate. The fan-shaped moving plate slides inside the fan-shaped hollow column. A guide column is connected to the side of the fan-shaped moving plate. A connecting plate is connected to one end of the guide column. A connecting block is welded to the side of one of the connecting plates, and a drying box for drying the semi-finished petroleum fracturing proppant is installed on the side of the other connecting plate.

[0006] Preferably, the connecting block has a rotating groove inside for rotation, and a rotating column is rotatably connected inside the rotating groove. A crushing wheel for crushing semi-finished oil fracturing proppant is installed at the end of the rotating column.

[0007] Preferably, the bottom of the drying box is provided with an air inlet for air intake, and a fan is installed inside the air inlet.

[0008] Preferably, the vertical inner wall of the drying box is equipped with a heating pipe for drying semi-finished petroleum fracturing proppant, and multiple hot air nozzles are provided on both sides of the drying box for hot air ejection.

[0009] Preferably, the bottom of the drying drum is equipped with support feet for support, the top of the drying drum is equipped with a top cover, and a motor is installed on the top of the top cover.

[0010] Preferably, the output shaft of the motor is connected to a stirring shaft via a coupling, and a guide disc and a crushing disc are installed on the outer periphery of the stirring shaft. A support frame is welded to the vertical inner wall of the drying barrel.

[0011] Preferably, the outer periphery of the drying drum is connected to an inlet pipe for the entry of semi-finished oil fracturing proppant, and the bottom of the drying drum is connected to an outlet pipe.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This oil fracturing proppant semi-finished product drying equipment benefits from the structure of the crushing wheel. The stirring shaft drives the guide plate and the crushing plate to rotate, and the crushing plate drives the oil fracturing proppant semi-finished product that does not conform to the size to rotate. The oil fracturing proppant semi-finished product comes into contact with the crushing wheel, and the crushing wheel crushes the oil fracturing proppant semi-finished product. Compared with the traditional oil fracturing proppant semi-finished product drying equipment, which has a weak dispersing ability, this structure improves the dispersing ability. The dispersing structure can break up the agglomerated material, making it more dispersed before entering the drying equipment, increasing the contact area between the material and the hot air, and improving the drying efficiency.

[0014] This oil fracturing proppant semi-finished product drying equipment benefits from the structure of the fan-shaped hollow column. When encountering large particles of oil fracturing proppant semi-finished product, the semi-finished product will move the crushing wheel, connecting block, connecting plate and fan-shaped moving plate upward, and the spring will be squeezed. It can adapt to the contact pressure between the crushing wheel and the semi-finished product, and prevent damage to the parts.

[0015] This oil fracturing proppant semi-finished product drying equipment benefits from the structure of the drying box. Air comes into contact with the heating pipe through the air inlet, and the heated air is sprayed out from the hot nozzle. The hot air comes into contact with the oil fracturing proppant semi-finished product on the crushing disc to dry it, thus improving the drying efficiency. Attached Figure Description

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 The illustrated oil fracturing proppant semi-finished product drying equipment includes a drying drum 101 for preventing raw material leakage during the drying process. Two fixed plates 3 are welded to the vertical inner wall of the drying drum 101. A fan-shaped hollow column 301 is welded to the side of each of the two fixed plates 3. A spring 302 is connected inside the fan-shaped hollow column 301. A fan-shaped moving plate 303 is connected to the end of the spring 302 away from the fixed plate 3. The fan-shaped moving plate 303 slides inside the fan-shaped hollow column 301. A guide column 304 is connected to the side of the fan-shaped moving plate 303. A connecting plate 305 is connected to one end of the guide column 304. A connecting block 306 is welded to the side of one of the connecting plates 305. A drying box 4 for drying the oil fracturing proppant semi-finished product is installed on the side of the other connecting plate 305.

[0027] The bottom of the drying tank 101 is equipped with support feet 1 for support, and the top of the drying tank 101 is equipped with a top cover 102. The top of the top cover 102 is equipped with a motor 2. The output shaft of the motor 2 is connected to a stirring shaft 201 through a coupling. A guide plate 203 and a crushing plate 204 are installed on the outer periphery of the stirring shaft 201. The semi-finished petroleum fracturing proppant that does not meet the size requirements is left on the crushing plate 204. When the motor 2 is turned on, the motor 2 drives the stirring shaft 201 to rotate inside the support frame 202. The stirring shaft 201 drives the guide plate 203 and the crushing plate 204 to rotate. The crushing plate 204 drives the semi-finished petroleum fracturing proppant that does not meet the size requirements to rotate.

[0028] A support frame 202 is welded to the vertical inner wall of the drying drum 101. A rotating groove 307 for rotation is provided inside the connecting block 306. A rotating column 308 is rotatably connected inside the rotating groove 307. A crushing wheel 309 for crushing semi-finished petroleum fracturing proppant is installed at the end of the rotating column 308. The crushing disc 204 drives the semi-finished petroleum fracturing proppant that does not meet the size to rotate. The semi-finished petroleum fracturing proppant comes into contact with the crushing wheel 309, and the crushing wheel 309 crushes the semi-finished petroleum fracturing proppant. If large particles of semi-finished petroleum fracturing proppant are encountered, the semi-finished petroleum fracturing proppant will move the crushing wheel 309, the connecting block 306, the connecting plate 305 and the fan-shaped moving plate 303 upward. The spring 302 is squeezed, which can adapt to the contact pressure between the crushing wheel 309 and the semi-finished petroleum fracturing proppant, and prevent damage to the parts.

[0029] The bottom of the drying chamber 4 is provided with an air inlet 403 for air intake. A fan 404 is installed inside the air inlet 403. A heating tube 401 for drying semi-finished petroleum fracturing proppant is installed on the vertical inner wall of the drying chamber 4. Multiple hot air nozzles 402 for hot air ejection are provided on both sides of the drying chamber 4. When the fan 404 is turned on, air comes into contact with the heating tube 401 through the air inlet 403. The heated air is ejected from the hot air nozzles 402. The hot air comes into contact with the semi-finished petroleum fracturing proppant on the pulverizing disc 204 for drying.

[0030] The outer periphery of the drying drum 101 is connected to an inlet pipe 103 for the entry of semi-finished petroleum fracturing proppant. The bottom of the drying drum 101 is connected to an outlet pipe 104. The semi-finished petroleum fracturing proppant to be dried is added from the inlet pipe 103 to the crushing disc 204 inside the drying drum 101. The crushing disc 204 screens the semi-finished petroleum fracturing proppant. The semi-finished petroleum fracturing proppant that meets the size requirements enters the bottom of the drying drum 101. The heating equipment inside the drying drum 101 dries the semi-finished petroleum fracturing proppant. The dried semi-finished petroleum fracturing proppant is discharged from the outlet pipe 104. The drying drum 101 is equipped with heating elements and a material carrying device. The heating elements can be electric heating tubes, gas heating furnaces, or steam radiators, etc., used to generate heat to evaporate the moisture in the material.

[0031] Working principle

[0032] In operation, the semi-finished oil fracturing proppant drying equipment first feeds the semi-finished oil fracturing proppant to be dried into the pulverizing disc 204 inside the drying tank 101 through the feed pipe 103. The pulverizing disc 204 sieves the semi-finished oil fracturing proppant, and those that meet the required size enter the bottom of the drying tank 101. The heating equipment inside the drying tank 101 dries the semi-finished oil fracturing proppant, while those that do not meet the required size remain on the pulverizing disc 204. Then, the motor 2 is turned on, driving the stirring shaft 201 to rotate within the support frame 202. The stirring shaft 201 drives the guide disc 203 and the pulverizing disc 204 to rotate, and the pulverizing disc 204 rotates the semi-finished oil fracturing proppant that does not meet the required size. The semi-finished oil fracturing proppant comes into contact with the crushing wheel 309, which crushes the semi-finished oil fracturing proppant. If large particles of semi-finished oil fracturing proppant are encountered, the semi-finished oil fracturing proppant will cause the crushing wheel 309, connecting block 306, connecting plate 305, and fan-shaped moving plate 303 to move upward. The spring 302 is compressed, which can adapt to the contact pressure between the crushing wheel 309 and the semi-finished oil fracturing proppant, preventing damage to the parts. The blower 404 is turned on, and air comes into contact with the heating pipe 401 through the air inlet 403. The heated air is sprayed out from the hot nozzle 402. The hot air comes into contact with the semi-finished oil fracturing proppant on the crushing disc 204 to dry it. The dried semi-finished oil fracturing proppant is discharged from the discharge pipe 104.
