Description

Technical Field

[0001] The invention belongs to the technical field of cement pole processing and relates to a constant temperature cyclone drying device, in particular to a constant temperature cyclone drying device for cement pole production. Background Art

[0002] Cement poles are one of the common infrastructures. They are mainly composed of steel bars and concrete. They are very common in industry and life. They are mainly used as line support pillars in industries such as electricity, communications, railways and petroleum.

[0003] In the process of manufacturing cement poles, the injection-molded cement pole molds are steam-cured. Most of them use steam curing pools to steam-cure the cement poles to increase the hardening speed of the cement. Traditional steam curing devices use coal boilers to heat water into steam, and use high-temperature steam to heat and solidify the cement poles.

[0004] After curing, the cement poles will be dried, but the existing drying equipment generally only performs constant temperature drying on the outside of the cement poles and cannot perform constant temperature drying on the inside of the cement poles. This will cause different temperatures inside and outside, affecting the structural strength of the cement poles, and ordinary drying takes a long time.

[0005] Therefore, we propose a constant temperature cyclone drying device for cement pole production, which can provide a closed environment for constant temperature drying. It can perform constant temperature cyclone drying on the inside of the cement pole to ensure the constant temperature inside the cement pole, and can maintain constant temperature drying on the outside of the cement pole. It can accelerate the flow and reduce the drying time. The air outlet temperature can be adjusted in stages so that the temperature inside and outside the cement pole drops evenly during drying to ensure structural strength. Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a constant temperature cyclone drying device for cement pole production. The technical problem to be solved by this invention is: how to achieve stable, efficient and uniform constant temperature cyclone drying of cement poles to ensure the structural strength of the cement poles.

[0007] The purpose of the present invention can be achieved through the following technical solutions: A constant temperature cyclone drying device for cement pole production comprises a moving mechanism, a closing mechanism, a hot air blower 1, a hot air blower 2 and a blower mechanism 1, wherein the hot air blower 1 is arranged at the upper end of the rear side of the closing mechanism, and the air outlet of the hot air blower 1 is connected to the blower mechanism 1 by a pipeline, the hot air blower 2 is arranged on the moving mechanism, and the moving mechanism is located on the left side of the closing mechanism, a drying spiral rod and a support ring are provided on the moving mechanism, the support ring is rotatably arranged on the right side of the moving mechanism, and the support ring is sleeved on the outside of the drying spiral rod, an external drying mechanism is provided at the upper end of the closing mechanism, and a drying chamber is formed between the external drying mechanism and the closing mechanism, a blower mechanism 2 is provided between the external drying mechanism and the moving mechanism, the air outlet of the hot air blower 2 is respectively connected to the drying spiral rod and the blower mechanism 2 by pipelines, and the blower mechanism 1 is located on the right side of the external drying mechanism.

[0008] The working principle of the present invention is: the staff hoist the cement pole after steam curing and place it in the external drying mechanism. After placement, the blower mechanism moves and pushes the cement pole so that the cement pole is completely fitted into the external drying mechanism. At this time, the blower mechanism hits the right side of the external drying mechanism, and then the closing mechanism moves and closes. The closing mechanism cooperates with the external drying mechanism to cover the cement pole. Then the moving mechanism drives the drying spiral rod to slide in the support ring and pushes the drying spiral rod into the inner cavity of the cement pole. Finally, the drying spiral rod hits the end of the moving mechanism. Then the hot air blower 2 inputs the hot air into the inner cavity of the cement pole through the drying spiral rod, and after being guided by the drying spiral rod, a reflux cyclone is formed, and finally output through the right side of the drying spiral rod. At the same time, the hot air blower 2 inputs the hot air into the drying chamber through the blower mechanism 2, and after being guided by the drying chamber, the hot air is output as hot air. The cement poles are dried from left to right in a cyclone form and then output from the blower mechanism 1. At the same time, the hot air blower 1 inputs hot air into the drying chamber through the blower mechanism 1. After being guided through the drying chamber, the cement poles are dried from right to left in a hot cyclone form. The cyclone mode accelerates the flow and reduces the drying time. When drying the cement poles, the blower mechanism 1 and the blower mechanism 2 move alternately and adjust the opening and closing of the air outlet alternately so that the direction of the hot cyclone in the drying chamber changes alternately, so that the temperature inside the drying chamber is kept constant and evaporated water vapor is taken away when the air is discharged. When drying, the outlet temperature of the hot air blower 1 and the hot air blower 2 can also be evenly adjusted. After adjusting the temperature, the constant temperature drying is maintained for a period of time so that the temperature of the cement poles is evenly reduced during drying, the natural heat dissipation time of the cement poles is reduced, and the structural strength is ensured.

[0051] In this embodiment, when the drying spiral rod 7 extends into and out of the inner cavity of the cement pole, the support ring 56 rotates in the mounting hole 41, and the avoidance hole 2 55 and the two avoidance holes 1 54 facilitate the movement of the drying spiral rod 7.

[0052] The drying spiral rod 7 includes a mounting seat 50, a windshield circular plate 51 and an inner drying rod 52, which are arranged in sequence from left to right. The mounting seat 50 is detachably arranged in the mounting groove 45. Two symmetrically arranged ventilation holes 53 are opened on the windshield circular plate 51, and the two ventilation holes 53 are respectively located on both sides of the inner drying rod 52. One of the ventilation holes 53 is connected to the air outlet of the hot air blower 2 8 through a pipe. The inner drying rod 52 is slidably arranged in the avoidance hole 2 55. Two symmetrically arranged spiral plates 3 49 are fixed to the outside of the inner drying rod 52. The two spiral plates 3 49 are respectively slidably arranged in the avoidance hole 1 54. The length of the spiral plate 3 49 is longer than the inner drying rod 52, and a ventilation gap 48 is formed between the ends of the two spiral plates 3 49 and the inner drying rod 52. The right end of the inner drying rod 52 is slidably arranged in the support ring 56.

[0053] In this embodiment, the movable slide 47 drives the mounting seat 50, the windshield circular plate 51 and the inner drying rod 52 to move, driving the inner drying rod 52 to extend into the inner cavity of the cement pole until the windshield circular plate 51 abuts against the fixed block 42, and then the hot air blower 2 8 inputs hot air into the inner cavity of the cement pole through one of the vents 5 53, which is guided by two spiral plates 3 49 to form a hot cyclone in the inner cavity of the cement pole, and when it reaches the end of the inner drying rod 52, it flows back to the other vent 5 53 through the ventilation gap 48, and dries the cement pole in the form of a reflux hot cyclone from the inner cavity of the cement pole. The windshield circular plate 51 is used to seal the mounting hole 41.

[0054] The working principle of the present invention is as follows: the staff hoist the cement pole after steam curing and place it on several spiral support frames 24. After placement, the blower mechanism 15 moves, that is, the screw slide of the electric screw member 32 drives the sealing plate 27 and the fixed plate 1 28 to move to the left, and the sealing plate 27 abuts on the base 17 on the far right, and the sealing plate 27 seals the right side of the drying chamber and pushes the cement pole so that the cement pole is completely fitted into the outer drying mechanism 4. At this time, the blower mechanism 15 abuts on the right side of the outer drying mechanism 4, and then the closing mechanism 3 moves and closes, that is, the output shaft of the driving motor 10 drives the three double-threaded screw members 15 to move synchronously, and the double-threaded screw members 15 drive the push plates 12 at the corresponding positions to move, and the push plates 12 on both sides The arc plates 13 at the corresponding positions are driven to move toward the middle respectively. During the movement, the slider 9 slides on the outer drying mechanism 4. The two arc plates 13 conflict with each other after moving one end distance, and then stop moving. The arc connecting strip 16 is used to fix the slider 9. The slider 9 is used to keep the arc plates 13 moving stably. The spiral plates 14 of the two arc plates 13 match each other to form a guide structure inside the drying chamber. The closing mechanism 3 cooperates with the outer drying mechanism 4 to cover the cement pole. Then the moving mechanism 1 drives the drying spiral rod 7 to slide in the support ring 56 and pushes the drying spiral rod 7 into the inner cavity of the cement pole. Finally, the drying spiral rod 7 conflicts with the end of the moving mechanism 1, that is, the output shaft of the driving motor 46 drives the screw shaft 44 to rotate, and the screw shaft 44 drives the moving mechanism 1. The movable slide 47 slides on the two screw slide rails 43, and the movable slide 47 drives the mounting seat 50, the windshield circular plate 51 and the inner drying rod 52 to move, driving the inner drying rod 52 to extend into the inner cavity of the cement pole until the windshield circular plate 51 abuts against the fixed stopper 42, and then the hot air blower 2 8 inputs the hot air into the inner cavity of the cement pole through the drying spiral rod 7, and forms a return cyclone after being guided by the drying spiral rod 7, and is finally output through the right side of the drying spiral rod 7, that is, the hot air blower 2 8 then inputs the hot air into the inner cavity of the cement pole through one of the vents 5 53, and forms a hot cyclone in the inner cavity of the cement pole after being guided by the two spiral plates 3 49, and when it reaches the end of the inner drying rod 52, it flows back to the other vent 5 53 through the ventilation gap 48, and flows into the inner cavity of the cement pole with a hot cyclone. The cement pole is dried from the inner cavity of the cement pole in the form of a reflux hot cyclone. At the same time, the hot air blower 2 8 inputs hot air into the drying chamber through the blower mechanism 2 2. After being guided through the drying chamber, the cement pole is dried from left to right in the form of a hot cyclone. That is, the output shaft of the drive motor 34 drives the turntable 2 35 to rotate intermittently. When the turntable 2 35 rotates, the ventilation pipe 2 36 and the ventilation pipe 3 38 are alternately connected to the ventilation port 3 33. When the ventilation pipe 2 36 is connected to the ventilation port 3 33, hot air is output. When the ventilation pipe 3 38 is connected to the ventilation port 3 33, hot air is input, thereby realizing intermittent input and output of hot air from the left end of the drying chamber to realize cyclonic drying, and then output from the blower mechanism 1 5. At the same time, the hot air blower 1 6 inputs hot air into the drying chamber through the blower mechanism 1 5.After being guided by the drying chamber, the cement pole is dried from right to left in the form of a hot cyclone, that is, the output shaft of the driving motor 29 drives the turntable 1 26 to rotate intermittently. When the turntable 1 26 rotates, the vent 25 and the ventilation pipe 1 30 are alternately connected to the vent 4 31. When the vent 4 31 is connected to the vent 25, hot air is output, and when the vent 4 31 is connected to the ventilation pipe 1 30, hot air is input, thereby realizing intermittent input and output of hot air from the right end of the drying chamber, realizing cyclone drying, and accelerating the flow through the cyclone mode to reduce the drying speed. It is time-consuming, and when drying cement poles, the blower mechanism 1 5 and the blower mechanism 2 2 move alternately, alternately adjusting the opening and closing of the air outlet, so that the direction of the hot cyclone in the drying chamber changes alternately, so that the temperature inside the drying chamber is maintained constant and evaporated water vapor is taken away when the air is discharged. During the drying process, the outlet temperature of the hot air blower 1 6 and the hot air blower 2 8 can also be evenly adjusted. After the temperature is adjusted, the constant temperature drying is maintained for a period of time, so that the temperature of the cement pole is evenly reduced during the drying process, reducing the natural heat dissipation time of the cement pole and ensuring the structural strength.

[0055] In summary, the outer drying mechanism 4 cooperates with the closing mechanism 3 and the blower mechanism 5 to cover the cement pole, providing a closed environment for easy drying. The drying spiral rod 7 is driven by the moving mechanism 1 to slide on the support ring 56, so that the drying spiral rod 7 can extend into and out of the inner cavity of the cement pole, and cooperate with the hot air blower 2 8 to perform constant temperature cyclone drying on the cement pole from the inside to ensure a constant temperature inside the cement pole; Hot air is intermittently inputted into the drying chamber from the blower mechanism 2 through the hot air blower 2 8, and hot air is intermittently inputted into the drying chamber from the blower mechanism 1 5 through the hot air blower 1 6. During drying, the blower mechanism 1 5 and the blower mechanism 2 2 move alternately, and the opening and closing of the air outlet are adjusted alternately, so that the direction of the hot cyclone in the drying chamber is alternately changed, so that the outside of the cement pole is kept at a constant temperature and dried, and the flow is accelerated by the cyclone mode, thereby reducing the drying time. The air outlet temperature is adjusted in stages by hot air blower 2 8 and hot air blower 1 6, so that the temperature inside and outside the cement pole drops evenly during drying, ensuring the structural strength.
