Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to an energy-saving cement pole forming mold. Background Technology

[0002] Energy-saving cement pole forming molds are high-efficiency, low-consumption special steel molds for the centrifugal method of producing concrete poles. They are made of high-strength steel with an upper and lower split structure and are equipped with core structures such as quick-release sealing components and heat-insulated steam chambers. Relying on energy-saving designs such as heat energy recycling, lightweight drag reduction, and leak-proof sealing, they effectively reduce steam and electricity consumption in the production process. The pole forming can be completed through mold closing and material distribution, centrifugal compaction, energy-saving steam curing, and rapid demolding. They have the advantages of low energy consumption, high production efficiency, good finished product quality, low operation and maintenance costs, and long service life. They are widely used in the green industrial production of cement poles in fields such as power grids and photovoltaics.

[0003] In actual production, after the concrete blank is centrifugally compacted in the mold cavity, carbon dioxide is usually introduced into the molding cavity through the air injection port at one end of the mold. This allows the carbon dioxide to fully contact the concrete pole blank and undergo a carbonation reaction, thereby increasing the strength of the blank, achieving carbon fixation, and generating a dense calcium carbonate structure, which significantly enhances the mechanical properties and impermeability and frost resistance of the pole. However, in the existing process, excess carbon dioxide that has not participated in the reaction is directly discharged into the external environment through the gas exhaust hole at the other end of the mold. This not only wastes carbon dioxide gas and increases carbon emissions from production, but also the impurities carried in the exhaust gas can easily pollute the production workshop environment, endangering the health of on-site workers and increasing occupational health risks for them. This process fails to meet the low-carbon, environmentally friendly, and safe production requirements of the building materials production industry. Summary of the Invention

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] An energy-saving cement pole forming mold, such as Figure 1 - Figure 11As shown, the mold body 1 includes an air inlet and an air outlet at its two ends. This mold body 1 is existing technology and mainly includes an upper mold and a lower mold, both of which are split-type energy-saving steel molds. After the upper mold and the lower mold are closed and fixed, they form the mold body 1. The air inlet and air outlet of the mold body 1 are through slots. When it is necessary to introduce carbon dioxide gas into the mold body 1, the output end of the carbon dioxide gas supply system is connected and fixed to the air inlet of the mold body 1 to introduce the gas into the mold body 1 to participate in the carbonization reaction. The air outlet is used to discharge the unreacted mixed gas after the carbonization reaction. It should be noted that the mold body 1 is used with a centrifuge, which can rotate at high speed to complete the centrifugal compaction molding of the concrete blank. In addition, this mold body 1 will be used in conjunction with a corresponding frame and electrical control system. The frame and electrical control system are existing technologies and will not be described in detail here. In order to facilitate the collection and filtration of carbon dioxide gas discharged from the gas outlet of the mold body 1, this device also includes: mounting base 2, connecting pipe 3, one-way gas outlet mechanism 7, sliding component, docking block 4, gas guiding component 6, filter component 9, and gas storage component 8. The mounting base 2 is located at the air outlet of the mold body 1. The bottom of the mounting base 2 is provided with two parallel linear guide rails 55. The mounting base 2 is slidably connected to the linear guide rails 55 via a sliding bar 56. The linear guide rails 55 extend axially along the air outlet of the mold body 1. The ends of the two linear guide rails 55 away from the mold body 1 are connected to a mounting plate 57. A telescopic rod 58 is installed on the mounting plate 57 along the extension direction of the linear guide rails 55. The movable end of the telescopic rod 58 is connected to the mounting base 2, which can drive the mounting base 2 to move axially along the guide rails, adapting to the adjustment of the docking distance of molds of different specifications and improving the versatility of the device. The input end of the connecting pipe 3 is detachably connected to the air outlet end of the mold body 1 and is coaxially arranged with the air outlet end of the mold body 1; the one-way air outlet mechanism 7 is arranged inside the connecting pipe 3 to prevent the gas inside the mold body 1 from leaking to the outside, and to achieve air circuit sealing and leak prevention under normal conditions; the sliding component is arranged above the mounting base 2 and can move back and forth along the axis of the connecting pipe 3. The docking block 4 is mounted on the sliding assembly. A vent hole 42 is provided through the interior of the docking block 4 along its axial direction. One end of the docking block 4 is movably engaged with the output end of the connecting pipe 3, and a push pipe 5 is coaxially connected to the end. The docking block 4 drives the one-way air outlet mechanism 7 through the push pipe 5, so that both ends of the connecting pipe 3 are in a through state. The input end of the air guiding assembly 6 is connected to the output end of the vent hole 42. The filter assembly 9 is mounted on the mounting base 2, and its input end is connected to the output end of the air guiding assembly 6. It is used to filter impurities in the gas. The gas storage assembly 8 is mounted on the mounting base 2, and its input end is connected to the output end of the filter assembly 9. It is used to store the gas filtered by the filter assembly 9. In the initial state, the connecting pipe 3 is detachably connected to the air outlet end of the mold body 1 via a bolt mechanism, and the connecting pipe 3 is connected to the air outlet end. Under the action of the one-way air outlet mechanism 7, the connecting pipe 3 is in a closed state, ensuring that the gas inside the mold body 1 will not leak. When the air pressure sensor on the mold body 1 senses that the internal air pressure is higher than the threshold, the sliding component drives the docking block 4 to move towards the position of the connecting pipe 3. The actuating pipe 5 moves with the docking block 4. After the actuating pipe 5 contacts the one-way air outlet mechanism 7, it drives the one-way air outlet mechanism 7 to run, so that both ends of the connecting pipe 3 are in a closed state. In the through state, the gas inside the mold body 1 flows outward along the connecting pipe 3. Because the docking block 4 is snapped onto the end of the connecting pipe 3, the two are in a sealed connection state. After the gas flows out through the connecting pipe 3, it flows along the vent hole 42 in the docking block 4 and enters the input end of the gas guiding component 6. The gas guiding component 6 introduces the gas containing impurities into the filter component 9. The filter component 9 will filter the gas and remove the impurities mixed in the gas. The gas filtered by the filter component 9 will be received by the gas storage component 8 and stored for subsequent recycling. Specifically, the one-way air outlet mechanism 7 includes a fixed sleeve 10, a movable rod 11, a sealing plate 12, a sealing ring 13, and a return spring 14; The fixed sleeve 10 is coaxially connected to the connecting tube 3 via a radial bracket. One end of the movable rod 11 is coaxially slidably connected to the fixed sleeve 10. The return spring 14 is located inside the fixed sleeve 10, and its two ends are connected to the fixed sleeve 10 and the movable rod 11, respectively. The sealing plate 12 is coaxially connected to the end of the movable rod 11 away from the fixed sleeve 10. The sealing plate 12 is in contact with the inner wall of the output end of the connecting tube 3. The sealing ring 13 is coaxially located on the side of the sealing plate 12 near the output end of the connecting tube 3. Under normal conditions, the return spring 14 pushes the sealing plate 12 to tightly contact the inner wall of the output end of the connecting tube 3, and the sealing ring 13 forms a surface seal to prevent the gas inside the mold from leaking out, thus solving the problems of gas leakage and unstable gas pressure in traditional molds.

[0024] When the sliding component drives the docking block 4 to move axially, the jacking tube 5 can push the sealing plate 12 to compress the return spring 14, causing the sealing plate 12 to disengage from the inner wall of the connecting tube 3, thus achieving air passage. The buffer pad 37 avoids rigid collision damage to components and improves structural stability.

[0025] Several guide protrusions 15 are equidistantly connected on the inner wall of the connecting pipe 3 around its axis. The outer wall of the sealing plate 12 is provided with directional protrusions 16 corresponding to the several guide protrusions 15, and the directional protrusions 16 extend radially along the sealing plate 12. The directional protrusions 16 are slidably connected to the guide protrusions 15. A pressure sensor 17 is provided on the inner wall of the output end of the connecting pipe 3. The sensing end of the pressure sensor 17 is in contact with the outer wall of the docking block 4.

[0026] The sliding assembly includes a stabilizing bracket 18, two sliding rods 19, a fixing sleeve 20, a fixing tube 21, an umbrella bearing 22, a rotating tube 23, a mounting tube 24, and a telescopic rod 25. The stabilizing bracket 18 is mounted on the mounting base 2. Two sliding rods 19 are located on both sides of the docking block 4. Both sliding rods 19 are mounted on the stabilizing bracket 18 via the tube frame 27. The sliding rods 19 extend axially along the docking block 4. The fixing tube 21 is coaxially arranged with the docking block 4. The fixing sleeve 20 is located on the outer wall of the fixing tube 21, and both ends of the fixing sleeve 20 are slidably connected to the two sliding rods 19. The umbrella bearing 22 is coaxially arranged on the end of the fixing tube 21 near the docking block 4, and the inner ring of the umbrella bearing 22 is flush with the outer wall of the fixing tube 21. The inner wall of one end of the rotating tube 23 is connected to the outer ring of the umbrella bearing 22. One end of the mounting tube 24 is coaxially connected to the rotating tube 23, and the other end is coaxially connected to the docking block 4. The telescopic rod 25 is installed on the mounting base 2 through the gantry bracket 26, and the telescopic rod 25 is set along the extension direction of the sliding rod 19. The movable end of the telescopic rod 25 is connected to the fixed tube 21. In this structure, the umbrella bearing 22 achieves dynamic and static separation, that is, the fixed tube 21 remains stationary, while the rotating tube 23, mounting tube 24, and docking block 4 can rotate freely, which is suitable for the centrifugal rotation of the mold body 1.

[0027] To enable the docking block 4 and the connecting pipe 3 to rotate synchronously, a synchronization component is provided on the sliding component. The docking block 4 can rotate synchronously with the connecting pipe 3 through the synchronization component. The synchronization component includes a sliding sleeve 28, a directional rod 29, a toothed ring 30, and a telescopic spring 31. Among them, an annular plate 32 is coaxially connected to the connecting pipe 3, and a grooved ring 33 is fixedly connected to the annular plate 32. The toothed ring 30 is located on the side of the mounting pipe 24 near the docking block 4. Several toothed grooves 34 are equidistantly opened on the inner side wall of the grooved ring 33 around its axis. The outer side wall of the toothed ring 30 is provided with teeth 35 corresponding to the toothed grooves 34 one by one, and the teeth 35 and toothed grooves 34 are movably engaged. Several directional rods 29 are provided, one end of each directional rod 29 is connected to the toothed ring 30, and the directional rods 29 are equidistantly arranged around the axis of the toothed ring 30. The number of sliding sleeves 28 is the same as the number of directional rods 29. The sliding sleeves 28 are connected to the mounting pipe 24. One end of the directional rod 29 passes through the corresponding sliding sleeve 28 and extends to the side of the mounting pipe 24 near the rotating pipe 23. A telescopic spring 31 is sleeved on the outer wall of each directional rod 29. The two ends of the telescopic spring 31 are connected to the toothed ring 30 and the corresponding sliding sleeve 28, respectively.

[0028] When the docking block 4 axially docks with the connecting pipe 3, the telescopic spring 31 pushes the toothed ring 30 into the toothed groove 34 of the grooved ring 33, forming a circumferential limit, so that the docking block 4, the connecting pipe 3, and the mold body 1 rotate synchronously; when separating, the toothed ring 30 automatically disengages without motion interference, taking into account both docking sealing and rotation synchronization, ensuring continuous and stable conduction of the carbonization gas path. When the docking block 4 contacts the end of the connecting pipe 3, the pressure sensor 17 abuts against the outer wall of the docking block 4, which is used to detect the docking position signal in real time, realize the automatic triggering of the electrical control, and improve the operating accuracy of the device.

[0029] The docking block 4 has an umbrella-shaped structure, and its cross-sectional area gradually decreases as one end of the docking block 4 extends axially from the body to the connecting tube 3. An elastic pad is provided on the outer wall of the docking block 4, and the elastic pad is in active contact with the inner wall of the output end of the connecting tube 3. Several through grooves are provided on the side wall of the jacking tube 5, and a buffer pad 37 is connected to the end of the jacking tube 5 away from the docking block 4.

[0030] The air guiding assembly 6 includes an air guiding tube and a telescopic tube 38; The air vent 42 at one end of the air guide tube is connected to the output end of the air vent 42, and the other end extends to the outside through the mounting tube 24, the rotating tube 23 and the fixing tube 21. The guiding airway includes a rotating airway 39, a fixed airway 40, and a rotary joint 41. The input end of the rotating airway 39 is connected to the output end of the vent 42, and the output end of the rotating airway 39 is connected to one end of the rotary joint 41. The other end of the rotary joint 41 is connected to the input end of the fixed airway 40, and the output end of the fixed airway 40 is connected to the input end of the telescopic tube 38. The rotating airway 39 rotates synchronously with the docking block 4. The rotary joint 41 enables interference-free connection between the rotating tube 23 and the stationary tube. The fixed airway 40 is connected to the telescopic tube 38, which can adaptively move axially to avoid tube pulling or bending, ensuring smooth air delivery.

[0031] The filter assembly 9 adopts a redundant design and mainly includes a reversing pipe 43, a filter cartridge 44, a filter element 45, a manifold 47, and an electric three-way valve 46. The electric three-way valve 46 has two output ends connected to reversing pipes 43, and the output end of the telescopic pipe 38 is connected to the input end of the electric three-way valve 46. There are two filter cartridges 44, and the input end of the filter cartridge 44 is detachably connected to the corresponding output end of the reversing pipe 43. The manifold 47 has two input ends, and the output end of the filter cartridge 44 is detachably connected to the corresponding input end of the manifold 47. There are several filter elements 45, all of which are installed inside the filter cartridge 44. It should be noted that the filter elements 45 are multi-stage filter elements 45, and each filter element 45 performs a different function to improve the filtration effect of the filter assembly 9. In order to facilitate the detection of the degree of blockage of the filter elements 45, corresponding air pressure sensors are provided at both ends of the filter cartridge 44. When the filter element 45 is blocked, the air pressure sensor will sense the change in air pressure at both ends of the filter cartridge 44. When the change in air pressure exceeds the threshold, it indicates that the filter element 45 is in a severely blocked state and needs to be replaced by the worker in time.

[0032] The filter assembly 9 can switch filters without stopping the machine: when the filter element 45 in a single filter cartridge 44 is blocked, the electric three-way valve 46 automatically switches to another set of filter cartridges 44, and the blocked filter element 45 can be disassembled and replaced without interrupting production. At the same time, it filters impurities such as cement dust and water vapor in the gas, solving the problem of waste gas polluting the workshop and endangering personnel health. The purified gas meets the recycling standards.

[0033] The gas storage assembly 8 includes a booster pump 48, an input gas pipe 49, an output gas pipe 50, a gas storage cylinder 51, a second pressure sensor 52, a first solenoid valve 53, and a second solenoid valve 54.

A solenoid valve 53 is installed on the input air pipe 49. One end of the output air pipe 50 is connected to the output end of the booster pump 48. Two gas cylinders 51 are provided, both of which are detachably connected to the mounting base 2. The gas cylinders 51 can be installed on the mounting base 2 by bolt fixing. A solenoid valve 54 and a pressure sensor 52 are provided on the air inlet end of each of the two gas cylinders 51. The sensing end of the pressure sensor 52 extends into the interior of the gas cylinder 51 to monitor the gas pressure inside the cylinder in real time. The output air pipe 50 has two output ends, and the two output ends of the output air pipe 50 are respectively connected to the air inlet ends of the two gas cylinders 51. In this structure, when one gas cylinder 51 is full, it automatically switches to the other gas cylinder 51. The full-pressurized gas cylinder can be disassembled and replaced, realizing continuous carbon dioxide recovery, eliminating gas waste, and significantly reducing carbon emissions from production.

[0034] like Figure 1 - Figure 11 As shown, the working principle and usage process of this embodiment are as follows: The device is in the initial standby state. The telescopic rod 25 maintains its retracted stroke, driving the fixed sleeve 20 to move backward along the sliding rod 19, so that the docking block 4 and the output end of the connecting pipe 3 maintain a separation distance. At this time, in the one-way air outlet mechanism 7, the return spring 14 releases elastic force in the fixed sleeve 10, pushing the movable rod 11 to extend outward, driving the sealing plate 12 to stick tightly to the inner wall of the output end of the connecting pipe 3, and the sealing ring 13 forms an axial static seal, sealing the internal air passage of the connecting pipe 3. At this time, the inner cavity of the mold body 1 is in a sealed state, and there is no carbon dioxide gas leakage. In the synchronization component, the telescopic spring 31 is in a naturally extended state, and the toothed ring 30 and the grooved ring 33 remain separated and do not mesh. Meanwhile, the mold body 1 rotates at high speed in the circumferential direction with the external centrifuge (not shown in the figure), and the internal concrete blank is uniformly and densely formed under the action of centrifugal force, completing the pole foundation forming process. When the carbon dioxide pressure inside the mold body 1 reaches the preset carbonization reaction threshold, the control system issues a drive command. The telescopic rod 2 58 moves first, pushing the mounting base 2 to move axially along the linear guide rail 55. The axial distance between the mounting base 2 and the air outlet end of the mold body 1 is completed to achieve overall alignment. Then the telescopic rod 25 extends, pushing the fixed tube 21 and the fixed sleeve 20 to move smoothly forward along the sliding rod 19, driving the rotating tube 23, the mounting tube 24 and the docking block 4 to move axially towards the connecting tube 3 simultaneously. One end of the docking block 4 is inserted into the output end of the connecting tube 3, and the outer wall elastic pad is pressed against the inner wall of the connecting tube 3 to form a radial dynamic seal. During the docking process, the jacking tube 5 first contacts the sealing plate 12 and continuously applies axial thrust to overcome the elastic force of the return spring 14, pushing the movable rod 11 to retract into the fixed sleeve 10. The sealing plate 12 disengages from the inner wall of the connecting tube 3, and the air passages at both ends of the connecting tube 3 are fully connected. At the same time, the pressure sensor 17 contacts the outer wall of the docking block 4, triggers the positioning signal and feeds it back to the control system. In the synchronization component, the telescopic spring 31 pushes the toothed ring 30 to move axially. The teeth 35 on the outer wall of the toothed ring 30 are engaged in the toothed groove 34 on the inner wall of the grooved ring 33, forming a circumferential rigid connection. This allows the docking block 4, the mounting tube 24, and the rotating tube 23 to rotate synchronously at high speed with the connecting tube 3 and the mold body 1. The umbrella bearing 22 realizes the dynamic and static separation of the rotating parts and the stationary fixed tube 21. The carbon dioxide mixture in the inner cavity of the mold body 1 that did not participate in the carbonization reaction flows into the connecting pipe 3 from the outlet under the action of pressure difference, and enters the axial ventilation hole 42 of the docking block 4 through the ventilation groove on the side wall of the push pipe 5; the gas flows into the rotating air pipe 39 of the air guide assembly 6 in sequence, smoothly transitions to the fixed air pipe 40 through the rotary joint 41, and is then transported to the filter assembly 9 through the telescopic pipe 38. The telescopic pipe 38 adaptively compensates for axial displacement to avoid pipe pulling deformation. After the gas enters the electric three-way valve 46, the control system directs the airflow to one of the filter cartridges 44. The multi-stage filter element 45 efficiently intercepts and filters cement dust, slurry impurities, and water vapor in the gas. When the pressure difference of the filter element 45 exceeds the standard, the electric three-way valve 46 automatically switches, and the airflow is switched to the backup filter cartridge 44. The staff can disassemble and replace the clogged filter element 45 online. The entire process does not require stopping the machine or interrupting production. The purified clean carbon dioxide gas is collected in the collection pipe 47, completing the purification of impurities throughout the entire process and eliminating the potential for pollution in the workshop. After the carbonization and carbonization process of the pole is completed, the control system controls the telescopic rod 25 to retract and reset, driving the docking block 4 to axially exit the connecting pipe 3, and the jacking pipe 5 to remove the thrust on the sealing plate 12; the reset spring 14 rebounds and resets, pushing the sealing plate 12 to reseal the connecting pipe 3, the air passage is closed again, the toothed ring 30 and the grooved ring 33 in the synchronization component disengage, the rotation linkage is released, the mold body 1 stops centrifugal rotation, the telescopic rod 58 drives the mounting base 2 to reset along the linear guide rail 55, the device returns to the initial sealed standby state, and can quickly load materials and close the mold to enter the production cycle of the next cement pole, realizing continuous and automated operation.
