Description

Technical Field

[0001] The present invention relates to the field of heat preservation board preparation, and in particular to a low thermal conductivity heat preservation board preparation device and a method thereof. Background Art

[0002] External wall insulation board, also called Horizon building external wall decoration integrated board, includes rock wool insulation board, phenolic insulation board and cement foam insulation board. Among them, cement foam insulation board is a kind of external wall insulation board. Cement foam insulation board is a wall-porous rigid foam plastic made of cement, fly ash, flame retardant, foaming agent and other additives through scientific formula. The raw materials need to be dry mixed before adding water to mix, so that the various ingredients in the raw materials are mixed evenly.

[0003] However, the current dry mixing method of raw materials is that the raw materials are easily attached to the inner wall of the mixing barrel during the mixing process, and it is not easy to mix the raw materials at the bottom of the mixing barrel, which will cause some raw materials to not be mixed, resulting in insufficient mixing of the raw materials in the mixing barrel, and then the various ingredients in the raw materials are not mixed evenly, resulting in poor quality of the low thermal conductivity insulation board produced subsequently. Summary of the invention

The two stirring rods are symmetrically arranged. A plurality of air outlet holes are opened on the two stirring rods. Both stirring rods are connected to the ventilation hole in the stirring roller.

[0009] Furthermore, it is particularly preferred that the helical ring is a helical structure.

[0010] In addition, it is particularly preferred that a fan is also included, and the fan is fixedly connected to the top of the stirring roller, and the fan is communicated with the stirring roller.

[0011] In addition, it is particularly preferred that a stirring mechanism is also included, which is arranged on the stirring rod, and the stirring mechanism includes a scraper plate, a long plate, a mounting shaft and fan blades, three scraper plates are fixedly connected to each of the stirring rods, a long plate is fixedly connected to each of the stirring rods, a mounting shaft is fixedly connected to the long plate, and a fan blade is fixedly connected to the mounting shaft.

[0012] In addition, it is particularly preferred that a vibration mechanism is also included, which is arranged on the inner wall of the net barrel, and the vibration mechanism includes a mounting frame, a cam, a push rod and a reset spring. The upper part of the inner wall of the net barrel is connected to the mounting frame by bolts, and the stirring roller passes through the mounting frame. Two cams are fixedly connected to the stirring roller, and the two cams are symmetrically arranged. Four push rods are slidably connected to the mounting frame, and the four push rods are in contact with the cams. Reset springs are connected between the mounting frame and the four push rods.

[0013] A working method of a low thermal conductivity insulation board preparation device comprises the following working steps:

[0014] S1. The operator first pours the raw materials into the net barrel through the hopper, and then starts the motor, which drives the stirring rod and the scraper to rotate and stir the raw materials. Then the operator starts the fan, which drives the stirring rod and the scraper to rotate, and also causes the air outlet on the stirring rod to spray air, thereby blowing and stirring the raw materials. The motor also drives the cam to rotate intermittently to push the push rod to move horizontally, and the return spring will be compressed back and forth, so that the push rod moves horizontally and reciprocates to push the inner wall of the net barrel, so that the bottom of the net barrel moves up and down, and then shakes the raw materials in the net barrel. At the same time, the motor drives the spiral ring to rotate, and the spiral ring drives the raw materials at the bottom of the inner wall of the outer barrel to move upward and re-enter the net barrel for stirring;

[0015] S2. When the raw material mixing is completed, the operator turns off the motor, so that the spiral ring, cam, stirring rod and scraper plate stop rotating, and the push rod stops moving. The operator turns off the fan so that the air outlet holes on the stirring rod no longer spray air. Then, the operator opens the discharge cover to allow the raw materials to fall out.

[0016] The beneficial effects of the present invention are:

[0017] The operator starts the motor, so that the stirring rod will stir the raw materials in the net barrel. During the stirring process, some of the raw materials will fall into the outer barrel through the mesh holes on the net barrel. The rotation of the small gear will drive the gear ring to rotate, and the rotation of the gear ring will drive the outer barrel to rotate. The rotation of the outer barrel will drive the spiral ring to rotate, and the spiral ring will drive the raw materials at the bottom of the inner wall of the outer barrel to move upward, so that the raw materials can re-enter the net barrel through the mesh holes on the net barrel for stirring. In this way, the staff can stir the raw materials more conveniently and effectively improve the efficiency of stirring the raw materials.

[0018] When the operator starts the fan, air will be ejected through the air outlet on the stirring rod, thereby blowing the raw materials in the net barrel. In this way, the air ejected from the air outlet on the stirring rod can blow the raw materials in the net barrel, so that the various ingredients in the raw materials can be more fully mixed in the net barrel, thereby making the various ingredients in the raw materials more evenly stirred.

[0019] When the stirring roller drives the stirring rod to rotate, the stirring rod will drive the scraper plate to rotate, and at the same time, air will enter the stirring rod through the ventilation holes of the stirring roller. The air circulation will drive the fan blades to rotate, and the rotation of the fan blades will drive the installation shaft to rotate. The rotation of the installation shaft will drive the long plate to rotate, and the rotation of the long plate will drive the stirring rod to rotate. In this way, while the stirring roller drives the stirring rod to rotate, the stirring rod will also rotate on its own, so that the air sprayed from the air outlet on the stirring rod can be blown over a larger range and blow more raw materials for mixing, so that the various ingredients in the raw materials can be further stirred more fully in the net barrel, and the various ingredients in the raw materials can be further mixed more evenly.

[0020] When pulley two drives the stirring roller to rotate, the push rod will move to open the middle part of the inner wall of the net barrel due to its elasticity. The opening of the middle part of the inner wall of the net barrel will drive the bottom of the net barrel to move upward, and the cam will lose contact with the push rod. The bottom of the net barrel will move downward and reset under the action of gravity, and the net barrel will recover under the action of its own elasticity, and reciprocate in sequence, which will make the bottom of the net barrel move up and down, so that the raw materials in the net barrel will shake up and down, and the raw materials will fall into the outer barrel through the mesh holes on the net barrel, so that the raw materials in the net barrel can be discharged more thoroughly and the raw materials in the net barrel can be mixed more fully.

[0038] The stirring mechanism includes a motor 51, a stirring roller 52, a stirring rod 53 and a pulley assembly 54. The motor 51 is connected to the top of the mounting plate 4 by bolts. The stirring roller 52 is rotatably connected to the circular plate 2. A ventilation hole is opened in the stirring roller 52. Two stirring rods 53 are rotatably connected to the stirring roller 52. The two stirring rods 53 are symmetrically arranged. A plurality of air outlet holes are opened on the two stirring rods 53. The two stirring rods 53 are connected to the ventilation hole in the stirring roller 52. A pulley assembly 54 is arranged between the output shaft of the motor 51 and the stirring roller 52.

[0039] The pulley assembly 54 includes pulley 1, pulley 2 and a belt. The upper part of the output shaft of the motor 51 is connected to pulley 1 through a flat key, and the top of the stirring roller 52 is connected to pulley 2 through a flat key. A belt is wound between pulley 1 and pulley 2.

[0040] The circulating feeding mechanism includes an outer barrel 61, a gear ring 62, a pinion 63, a net barrel 64 and a spiral ring 65. The bottom of the circular plate 2 is connected to the net barrel 64 by bolts. The net barrel 64 is provided with a plurality of mesh holes. The outer barrel 61 is rotatably connected to the net barrel 64. The upper part of the outer wall of the outer barrel 61 is connected to the gear ring 62 by a flat key. The lower part of the output shaft of the motor 51 is connected to the pinion 63 by a flat key. The pinion 63 is meshed with the gear ring 62.

The bottom of the outer barrel 61 is connected to a discharge cover 66 by threads.

[0041] First, the operator pours the raw materials into the net barrel 64 through the hopper 3, and then the operator starts the motor 51. The rotation of the output shaft of the motor 51 will drive the pulley 1 and the pinion 63 to rotate. The rotation of the pulley 1 will drive the belt to rotate. The rotation of the belt will drive the pulley 2 to rotate. The rotation of the pulley 2 will drive the stirring roller 52 to rotate. The rotation of the stirring roller 52 will drive both stirring rods 53 to rotate. The stirring rod 53 will stir the raw materials in the net barrel 64. During the stirring process, some of the raw materials will fall into the outer barrel 61 through the mesh holes on the net barrel 64. The rotation of the pinion 63 will drive the gear ring 62 to rotate. The rotation of the gear ring 62 will drive the outer barrel 61 to rotate. The rotation of the outer barrel 61 will drive the spiral ring 65 When the outer barrel 61 is rotated, the spiral ring 65 will drive the raw materials at the bottom of the inner wall of the outer barrel 61 to move upward, so that the raw materials can re-enter the net barrel 64 through the mesh holes on the net barrel 64 for stirring; when the raw materials are stirred, the operator will open the discharge cover 66 to allow the raw materials to fall out and be discharged.

In this way, the stirring rod 53 can stir the raw materials at the bottom of the net barrel 64, so that the raw materials in the barrel can be more fully stirred.

[0042] Example 2

[0043] On the basis of Example 1, Figure 7 As shown, a fan 7 is also included. The fan 7 is fixedly connected to the top of the stirring roller 52 by bolts, and the fan 7 is communicated with the stirring roller 52.

[0044] The operator starts the fan 7, and the air inlet of the fan 7 will suck in air. The air will enter the ventilation channel of the stirring roller 52 through the fan 7, and the air will enter the stirring rod 53 through the ventilation channel of the stirring roller 52. The air will be ejected through the air outlet on the stirring rod 53, thereby blowing the raw materials in the net barrel 64. When the stirring of the raw materials is completed, the operator will turn off the fan 7. In this way, the air ejected from the air outlet on the stirring rod 53 can blow the raw materials in the net barrel 64, so that the various ingredients in the raw materials are more fully mixed in the net barrel 64, so that the various ingredients in the raw materials are stirred more evenly.

[0045] Example 3

[0046] On the basis of Example 2, Fig.10 As shown, it also includes a stirring mechanism, which is arranged on the stirring rod 53.

Each of the stirring rods 53 is connected to three scraper plates 81 by bolts, and each of the stirring rods 53 is connected to a long plate 82 by rivets. The long plate 82 is connected to the mounting shaft 83 by bolts, and the mounting shaft 83 is connected to the fan blade 84 by bolts.

[0047] When the stirring roller 52 drives the stirring rod 53 to rotate, the stirring rod 53 will drive the scraper plate 81 to rotate, and at the same time, air will enter the stirring rod 53 through the ventilation hole of the stirring roller 52, and the air circulation will drive the fan blade 84 to rotate, and the rotation of the fan blade 84 will drive the installation shaft 83 to rotate, and the rotation of the installation shaft 83 will drive the long plate 82 to rotate, and the rotation of the long plate 82 will drive the stirring rod 53 to rotate; when the raw materials are stirred, the operator turns off the motor 51 and the fan 7 to stop the stirring rod 53 from rotating. In this way, while the stirring roller 52 drives the stirring rod 53 to rotate, the stirring rod 53 will also rotate, so that the air sprayed from the air outlet on the stirring rod 53 can be blown over a larger range, blowing more raw materials for mixing, so that the various ingredients in the raw materials can be further stirred more fully in the net barrel 64, and the various ingredients in the raw materials can be further mixed more evenly.

[0048] Example 4

[0049] On the basis of Example 3, Figure 11-13As shown, a vibration mechanism is also included, and the vibration mechanism is arranged on the inner wall of the net barrel 64. The vibration mechanism includes a mounting frame 91, a cam 92, a push rod 93 and a reset spring 94. The upper part of the inner wall of the net barrel 64 is connected to the mounting frame 91 by bolts, and the stirring roller 52 passes through the mounting frame 91. Two cams 92 are connected to the stirring roller 52 by a flat key. The two cams 92 are symmetrically arranged. Four push rods 93 are slidably connected to the mounting frame 91. The four push rods 93 are in contact with the cam 92. Reset springs 94 are connected between the mounting frame 91 and the four push rods 93 through hooks.

[0050] When the second pulley drives the stirring roller 52 to rotate, the stirring roller 52 will drive the cam 92 to rotate, the cam 92 will contact the push rod 93, the return spring 94 will be compressed, the cam 92 will push the push rod 93 to move away from the stirring roller 52, the push rod 93 will contact the middle part of the inner wall of the net barrel 64, and because the net barrel 64 is elastic, the movement of the push rod 93 will open the middle part of the inner wall of the net barrel 64, and the opening of the middle part of the inner wall of the net barrel 64 will drive the bottom of the net barrel 64 to move upward, the stirring roller 52 will drive the cam 92 to continue to rotate, the cam 92 will be out of contact with the push rod 93, and the return spring 94 will be compressed. The return spring 94 returns to the position, and the return spring 94 returns to the position, which will drive the push rod 93 to move and return to the direction close to the stirring roller 52. The push rod 93 will break contact with the middle part of the inner wall of the net barrel 64, and the bottom of the net barrel 64 will move downward and return to its original position under the action of gravity. The net barrel 64 will recover under the action of its own elasticity, and the reciprocating movement in sequence will cause the bottom of the net barrel 64 to reciprocate up and down, so that the raw materials in the net barrel 64 will shake up and down, and the raw materials will fall into the outer barrel 61 through the mesh holes on the net barrel 64, so that the raw materials in the net barrel 64 can be discharged more thoroughly, and the raw materials in the net barrel 64 can be mixed more fully.
