[0038] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0039] The utility model provides a solid drag reducing agent drying device for oil well cement, comprising:

[0040] Box 1;

[0041] A sealing door 2 is hinged on one side wall of the box body 1 and is used to seal the box body 1;

[0042] The sliding plate 3 is arranged on the lower end surface inside the box body 1;

[0043] The carrying box 4 is arranged on the upper end surface of the sliding plate 3 and is used to contain the drag reducing agent;

[0044] The electric heating plate 5 is arranged on the inner side wall surface of the box body 1;

[0045] There are three electric heating plates 5, all of which are fixedly mounted on the side wall of the box 1 and connected to external power supply equipment, so as to heat the space inside the box 1 and heat and dry the drag reducing agent in the carrier box 4;

[0046] The sleeve 6 is rotatably mounted on the inner upper end surface of the box body 1;

[0047] The motor 17 is fixedly mounted on the upper end surface of the box body 1 and is used to drive the sleeve 6 to rotate;

[0048] The output end of the motor 17 is fixedly connected to the top of the sleeve 6, and when the output end rotates, the sleeve 6 can be driven to rotate;

[0049] A slide rod 7 is slidably mounted in the sleeve 6, and a bottom end thereof extends out of the sleeve 6;

[0050] A limiting assembly is arranged in the sleeve 6 and is used to limit the sliding rod 7;

[0051] A fixed rod 8, the outer surface of which is fixedly connected to the bottom end of the sliding rod 7;

[0052] Stirring rods 9, a number of which are fixedly mounted on the lower wall surface of the fixing rod 8;

[0053] A lifting device is arranged in the box body 1 and is used to drive the fixing rod 8 to move up and down;

[0054] Under the action of the lifting device, the fixed rod 8 can drive the stirring rod 9 to descend, so that the stirring rod 9 can be inserted into the carrying box 4. At the same time, under the action of the limiting component, the position of the sliding rod 7 in the sleeve 6 can be limited, so that when the sleeve 6 rotates, the sliding rod 7 can rotate at the same time. The rotation of the sliding rod 7 can drive the fixed rod 8 and the stirring rod 9 to rotate at the same time, so that the stirring rod 9 can stir the drag reducer in the carrying box 4 to make the drying more thorough.

[0055] Specifically, the limiter components include:

[0056] A limiting groove 10 is formed on the inner wall surface of the sleeve 6;

[0057] The limiting block 11 is fixedly mounted on the outer surface of the slide rod 7 and is slidably connected to the limiting groove 10 .

[0058] Specifically, the lifting device includes:

[0059] The first annular member 12 is disposed in the box body 1 and is located outside the sleeve 6;

[0060] The second annular member 13 is rotatably mounted on the outer side of the first annular member 12;

[0061] There are two connecting rods 14, one end of each of which is fixedly connected to the outer surface of the fixing rod 8, and the other end of each of which is fixedly connected to the lower end surface of the second annular member 13;

[0062] A support frame 15 is provided on the upper end surface of the box body 1;

[0063] The support frame 15 is fixedly mounted on the upper end surface of the box body 1 and can be kept fixed;

[0064] The third annular member 16 is disposed between the box body 1 and the support frame 15 and is located outside the motor 17;

[0065] A sliding rod 18, one end of which is fixedly connected to the lower end surface of the third ring member 16, and the other end of which slides through the upper wall of the box body 1 and is fixedly connected to the upper end surface of the first ring member 12;

[0066] The electric push rod 19 is arranged on the upper end surface of the support frame 15, and the telescopic end is fixedly connected to the upper end surface of the third ring member 16;

[0067] The extension of the telescopic end of the electric push rod 19 can drive the third ring member 16 to descend. The descent of the third ring member 16 can drive the sliding rod 18, the first ring member 12, the second ring member 13, the connecting rod 14 and the fixed rod 8 to descend at the same time, so that the stirring rod 9 is inserted into the carrier box 4. At the same time, when the fixed rod 8 descends, it can drive the sliding rod 7 to slide to the outside of the sleeve 6.

[0068] Specifically, an annular slide groove 20 is formed on the inner wall surface of the second annular member 13, and an annular slider 21 slidably connected to the annular slide groove 20 is fixedly installed on the outer wall surface of the first annular member 12;

[0069] Under the action of the annular sliding groove 20 and the annular sliding block 21 , the second annular member 13 can be more stable when rotating outside the first annular member 12 .

[0070] Specifically, a pair of slide grooves 22 are formed on the inner lower end surface of the box body 1, and a slider 23 slidably connected to the slide grooves 22 is fixedly mounted on the lower end surface of the sliding plate 3;

[0071] The staff can pull the sliding plate 3 to drive the slider 23 to slide out of the sliding groove 22, so that the sliding plate 3 can be moved out of the outside of the box body 1, which is convenient for the staff to collect the carrying box 4 and prevents the staff from reaching into the box body 1 and accidentally touching the electric heating plate 5, thereby causing burns to the staff.

[0072] Specifically, an arc-shaped limit block 24 is fixedly mounted on the upper end surface of the sliding plate 3, and the inner wall surface of the arc-shaped limit block 24 contacts the outer wall surface of the carrying box 4;

[0073] The arc-shaped limiting block 24 can limit the position of the carrying box 4 , making it convenient for the lifting device to drive the fixing rod 8 to descend so that the stirring rod 9 can be inserted into the carrying box 4 .

[0074] Working principle: the staff first places the carrier box 4 filled with drag reducer on the upper end surface of the sliding plate 3, and makes its outer wall surface contact with the inner wall surface of the arc-shaped limit block 24. At this time, the staff closes the sealing door 2 to seal the box body 1, and starts the electric push rod 19 at the same time. The telescopic end of the electric push rod 19 extends, which can drive the third annular member 16 to descend. The descent of the third annular member 16 can drive the sliding rod 18, the first annular member 12, the second annular member 13, the connecting rod 14 and the fixed rod 8 to descend at the same time, so that the stirring rod 9 is inserted into the carrier box 4. At this time, the staff starts the motor 17. The rotation of the output end of the motor 17 can drive the sleeve 6 to rotate. At this time, under the action of the limit groove 10 and the limit block 11, the sliding rod 7 can be rotated at the same time, and the rotation of the sliding rod 7 can drive the fixed rod 8 to rotate. The fixed rod 8 and the stirring rod 9 rotate, so that the stirring rod 9 stirs the drag reducer in the carrier box 4 to make it dry more evenly. At the same time, when the fixed rod 8 rotates, it can drive the connecting rod 14 to make the second ring member 13 rotate on the outer wall surface of the first ring member 12, which can make the rotation of the fixed rod 8 and the stirring rod 9 more stable. After the drying is completed, the staff turns off the electric heating plate 5 and the motor 17, and starts the electric push rod 19 at the same time to shrink the telescopic end thereof, so that the fixed rod 8 rises and the stirring rod 9 rises out of the outside of the carrier box 4. At this time, the staff opens the sealing door 2 and pulls the sliding plate 3. At this time, under the action of the slide groove 22 and the slider 23, the sliding plate 3 can slide out of the box body 1, which is convenient for the staff to collect the drag reducer in the carrier box 4, bringing convenience to people.
