Description

Technical Field

[0001] The present invention belongs to the technical field of heat exchange for electric pole maintenance, and in particular relates to an energy-saving steam curing pool heat exchange device for cement electric pole production. Background Art

[0002] In the production of cement poles, they need to be cured for a period of time after centrifugal forming before use to ensure that they have sufficient strength. During the curing process, energy-saving curing pools are usually used to maintain the cement poles.

[0003] For example, in the field of cement pole steam curing technology, patent application CN119748629A discloses equipment and methods for steam curing cement poles based on energy-saving building materials. The equipment comprises a steam curing pit comprising a triangular pit, a steel mold, a main cover plate, and an additional cover plate. A steam pipe is slidably connected to the rear of the triangular pit, a rotating jet ring is rotatably sleeved on the steam pipe, and an opening and closing mechanism is provided in front of the triangular pit. The present invention reduces and closes the steam curing space of the triangular pit as needed by splicing an appropriate number of additional cover plates onto the main cover plate; slides the steam pipe and inserts it into the opening and closing mechanism, thereby clamping the steam pipe and simultaneously connecting the steam; and then, the rotating jet ring rotates to eject steam, thereby uniformly steam curing the steel mold wrapped with the cement pole.

[0004] Combining the above cases and actual conditions, we found the following problems: In energy-saving curing pools, heat exchange equipment is usually installed to reuse excess heat during the curing process. However, condensed water is inevitable during the curing process. This condensed water is high-temperature condensed water and is generally discharged directly for recycling after curing. However, the heat it carries is not fully utilized. Summary of the Invention

[0005] The object of the present invention is to provide an energy-saving steam curing pool heat exchange device for cement pole production, so as to solve the problem of insufficient utilization of high-temperature condensed water generated during the curing process in the prior art.

[0010] The linkage structure includes a folding rod and a transmission plate; the folding rod is fixed to the bottom surface of the transmission plate, and a lower tooth plate is fixed to the inner end of the top surface of the transmission plate;

The sliding rods pass through the corresponding floating plates and the two are slidably connected. The top end of the sliding rod is fixed to the bottom surface of the partition plate, and the bottom end is fixed to the bottom surface of the preheating compartment.

[0018] The slide bar of this setting limits the up and down movement of the floating plate to prevent the floating plate from shaking and causing subsequent transmission to be unable to be realized.

[0019] In the technical solution of the present invention, the bottom end of the folding rod is fixed to the corresponding side of the connecting frame, the top end of the folding rod passes through the partition plate, the lowest height of the transmission plate is higher than the height of the placement frame, and a pump is fixed on the left inner wall of the preheating compartment, and the water outlet of the pump is connected to the condensation water pool.

[0020] This setup places the pump inside the preheating compartment to control the water level inside the preheating compartment.

[0021] In the technical solution of the present invention, a fixed block is provided near the outer end of the first rotating rod, the top of the fixed block is fixed to the top surface of the pool body, the first rotating rod passes through the fixed block and the two are rotatably connected, the first driven tooth is engaged with the lower tooth plate on the corresponding side, and the two lower tooth plates are symmetrically arranged about the left and right centers of the circle.

[0022] In this configuration, the fixed block can limit and support the position of the first rotating rod without affecting the rotation of the first rotating rod.

[0023] In the technical solution of the present invention, the top end of the steam inlet pipe passes through the top surface of the pool body and is connected to the external steam generating device.

[0024] In this arrangement, the helical tooth surface meshes with the bevel gear to ensure that the helical tooth surface can be driven to rotate by the bevel gear, and the inner gear block meshes with the third driven tooth to ensure that the inner gear block can drive the third driven tooth to rotate.

[0025] In the technical solution of the present invention, a second rotating rod is provided above the first rotating rod on the left side, the left end of the second rotating rod is embedded in the left inner wall of the pool body and the two are rotatably connected, a second driven tooth is coaxially fixed on the second rotating rod, an upper tooth plate is fixedly connected above the lower tooth plate, the diameter of the second driven tooth is larger than the diameter of the first driven tooth, the upper tooth plate is engaged with the second driven tooth, a horizontal butterfly valve is provided in the steam inlet pipe, the valve handle of the butterfly valve passes through the steam inlet pipe and is coaxially fixed to the right end of the second rotating rod.

[0026] In this setting, the upper tooth plate drives the second driven tooth to rotate, which in turn drives the butterfly valve to rotate and close the steam inlet pipe, so that the steam inlet pipe is opened and closed intermittently, reducing steam consumption and improving energy saving effects.

[0027] In the technical solution of the present invention, the tube structure includes a preheating tube, a first heating tube and a second heating tube. The front end of the preheating tube passes through the front side wall of the condensation water pool and is connected to the external water inlet, the middle section is in the shape of a serpentine tube and is located in the preheating compartment, and the rear end passes through the rear side wall of the preheating compartment and is connected to the bottom end of the first heating tube. The middle section of the first heating tube is in the shape of a serpentine tube and is arranged in the side box on the left, and the top end is connected to the top end of the second heating tube. The middle section of the second heating tube is in the shape of a serpentine tube and is arranged in the side box on the right, and the bottom end passes through the side box on the right and is connected to the external water outlet.

[0028] In this setting, the cold water introduced from the outside passes through the preheating tube, the first heating tube and the second heating tube in sequence for heat exchange. The serpentine tube section extends the flow distance of the cold water, thereby extending the heating time to ensure the preheating and heating effects.

[0029] In the technical solution of the present invention, the inner bottom surface of the side box is inclined with the inner side lower and the outer side higher. A spring plate is fixed to the inner bottom surface of the side box. A horizontally protruding rib is fixed to the top of the inner wall of the spring plate.

[0031] In this setting, the first rotating rod drives the top block to continuously lift the corrugated bar, and under the elastic force of the spring plate itself, the striking head strikes the first heating tube and the second heating tube, causing the attached high-temperature condensed water to fall quickly to avoid affecting the heating effect.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. In the present invention, by setting a preheating compartment, when cold water for heat exchange is introduced, it is first preheated by high-temperature condensed water and then heated by steam, which not only improves the utilization rate of high-temperature condensed water, but also improves the heat exchange efficiency.

[0034] 2. In the present invention, by setting a movable structure, a linkage structure and a rotating structure, when the high-temperature condensate water gradually increases, the float and the floating plate drive the transmission plate to rise. When the lower tooth plate rises to contact with the first driven tooth, it drives the first rotating rod to rotate, and then drives the bevel gear at the inner end to rotate, and drives the rotating ring to rotate through the oblique tooth surface, so that the inner tooth block and the third driven tooth rotate and drive the two steam nozzles to swing, so that the steam is sprayed more evenly, avoiding the situation where the local curing temperature is too high.

[0035] 3. In the present invention, by setting a second rotating rod, when the float and the float plate continue to rise until the second driven tooth contacts the upper tooth plate, it will drive the second driven tooth and the second rotating rod to rotate clockwise, driving the butterfly valve handle to rotate and gradually close. When the high-temperature condensate water level rises to trigger the pump to shut down, as the pump pumping water level drops, the second rotating rod will rotate counterclockwise, driving the butterfly valve handle to rotate and gradually open, thereby realizing intermittent steam delivery, reducing steam consumption, and further improving energy-saving effects.

[0050] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0051] Unless expressly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

[0052] Reference Figures 1-10 As shown, this embodiment provides a technical solution:

[0053] The energy-saving steam curing pool heat exchange device for cement pole production in the present invention includes a curing assembly 1, which includes a pool body 11 and a condensing water pool 16; the condensing water pool 16 is located below the pool body 11 and is divided by a partition plate 15. A preheating compartment 17 is provided in the middle of the condensing water pool 16. The preheating compartment 17 is provided to preheat cold water used for heat exchange to improve heat exchange efficiency. A steam assembly 3 is provided in the middle of the top surface of the curing assembly 1. Steam is introduced into the pool body 11 by providing the steam assembly 3 to cure the cement pole.

[0054] The heat exchange assembly 2 is provided in the pool body 11. The heat exchange assembly 2 includes a pipe structure 21, a movable structure 22, two linkage structures 23, and two rotating structures 25. The movable structure 22 is provided in the preheating compartment 17. The movable structure 22 drives the rotating structure 25 to rotate through the linkage structure 23.

[0055] The movable structure 22 includes four floating plates 221 and a plurality of floating balls 222. The floating balls 222 are evenly fixed below the four floating plates 221. The four floating plates 221 are connected and fixed by a square connecting frame 223. When the steam in the tank body 11 condenses into high-temperature condensed water, it falls and enters the preheating compartment 17 under the guidance of the partition plate 15. As the high-temperature condensed water increases, the water level in the preheating compartment 17 increases, causing the floating balls 222 to drive the floating plates 221 upward.

[0056] The linkage structure 23 includes a folding rod 231 and a transmission plate 232; the folding rod 231 is fixed to the bottom surface of the transmission plate 232, and a lower tooth plate 233 is fixed to the inner end of the top surface of the transmission plate 232; the rotating structure 25 includes a first rotating rod 251, a first driven tooth 252 and a bevel gear 253; the first rotating rod 251 and the first driven tooth 252 are coaxially fixed, and the bevel gear 253 is coaxially fixed to the inner end surface of the corresponding first rotating rod 251. When the floating plate 221 rises, the folding rod 231, the transmission plate 232 and the lower tooth plate 233 are driven to rise synchronously. When the lower tooth plate 233 contacts the first driven tooth 252, it drives the first rotating rod 251 to rotate, and then drives the inner end bevel gear 253 to rotate;

[0057] The steam assembly 3 includes a steam inlet pipe 31 and two steam nozzles 32; a swivel 33 is provided below the steam inlet pipe 31, and a beveled tooth surface 333 is provided on the bottom surface of the swivel 33. An inner tooth block 331 is fixed to the inner ring wall of the swivel 33, and a third driven tooth 321 is coaxially fixed to the side wall of the steam nozzle 32. When the bevel gear 253 rotates, the swivel 33 is driven to rotate by the beveled tooth surface 333, and then the two steam nozzles 32 are driven to swing through the inner tooth block 331 and the third driven tooth 321, so that the steam is sprayed more evenly and the local curing temperature is avoided from being too high.

[0058] See also Figure 1-Figure 3 As shown, in this embodiment, a sealed door 12 is hinged on the front side wall of the pool body 11, which is convenient for delivering cement poles into the pool body 11 for maintenance. Side boxes 13 are fixed on the left and right sides of the pool body 11. The side boxes 13 are connected to the inside of the pool body 11 and the two are formed as one piece. Two placement racks 14 are fixed symmetrically front and back by bolts above the partition plate 15 in the pool body 11, which is convenient for placing cement poles. An opening for condensed water to fall is provided in the middle of the partition plate 15, and the preheating compartment 17 is located directly below the opening. The top surface of the partition plate 15 is a slope with a low middle part and a high edge, which facilitates high-temperature condensed water to fall from the opening to the preheating compartment 17.

[0059] See also Figure 3-Figure 4As shown, in this embodiment, four floating plates 221 are regularly arranged at the four corners in the preheating compartment 17, and sliding rods 224 are provided at the four corners in the preheating compartment 17. The sliding rods 224 pass through the corresponding floating plates 221 and the two are slidably connected. The top end of the sliding rod 224 is bolted to the bottom surface of the partition plate 15, and the bottom end is bolted to the bottom surface of the preheating compartment 17. The floating plate 221 is limited by setting the sliding rod 224 to prevent the floating plate 221 from shaking left and right, which may cause subsequent transmission failure.

[0060] Furthermore, the bottom end of the folding rod 231 is welded and fixed to the corresponding side of the connecting frame 223, and the top of the folding rod 231 passes through the partition plate 15. The lowest height of the transmission plate 232 is higher than the height of the placement frame 14 to prevent the transmission plate 232 from blocking the placement of the cement pole. A pump 24 is fixed to the left inner wall of the preheating compartment 17, and the water outlet of the pump 24 is connected to the condensation water pool 16. The pump 24 is controlled by the water level of the preheating compartment 17. Specifically, it can be connected to the pump 24 through a signal line through a water level gauge. When the water level in the preheating compartment 17 is too high, the pump 24 starts to pump high-temperature condensed water into the condensation water pool 16, and is shut down when the water level in the preheating compartment 17 is too low. Controlling the opening and closing of the pump 24 by a water level gauge is a commonly used existing technology and will not be elaborated here. In addition, there is a water outlet on the rear side wall of the condensation water pool 16, which is not shown in the figure.

[0061] See also Figure 5-Figure 7 As shown, in this embodiment, a fixing block 254 is provided near the outer end of the first rotating rod 251, and the top of the fixing block 254 is fixed to the top surface of the pool body 11. The first rotating rod 251 passes through the fixing block 254 and the two are rotatably connected. The first rotating rod 251 is supported by setting the fixing block 254 without affecting the rotation of the first rotating rod 251. The fixing block 254 can be installed along the first rotating rod 251 according to actual conditions, and the first driven tooth 252 is engaged with the corresponding side lower tooth plate 233. The two lower tooth plates 233 are symmetrically arranged at the left and right circle centers, so that the first rotating rod 251 on the left rotates clockwise and the first rotating rod 251 on the right rotates counterclockwise, so that the rotating ring 33 rotates in the same direction under the drive of the left and right bevel gears 253.

[0062] See also Figure 7-Figure 8As shown, in this embodiment, the top end of the steam inlet pipe 31 passes through the top surface of the pool body 11 and is connected to the external steam generating device. The steam nozzle 32 is connected to the bottom surface of the steam inlet pipe 31 through a rotary joint. High-temperature steam enters from the steam inlet pipe 31 and is ejected from the steam nozzle 32 to maintain the cement pole. A mounting ring 332 is fixed to the top surface of the swivel 33. The mounting ring 332 is embedded in the pipe wall of the bottom surface of the steam inlet pipe 31 and the two are rotatably connected. The mounting ring 332 can support the swivel 33 without affecting the rotation of the swivel 33. The bevel gear surface 333 is engaged with the bevel gear 253, and the inner gear block 331 is engaged with the third driven gear 321. When the bevel gear 253 rotates, the swivel 33 is driven to rotate by the bevel gear surface 333, and then the two steam nozzles 32 are driven to swing through the transmission of the inner gear block 331 and the third driven gear 321.

[0063] See also Figure 6 and Figure 8 As shown, in this embodiment, a second rotating rod 26 is provided above the first rotating rod 251 on the left side. The left end of the second rotating rod 26 is embedded in the inner wall of the left side of the pool body 11 and the two are rotatably connected. A second driven tooth 261 is coaxially fixed on the second rotating rod 26, and an upper tooth plate 234 is fixedly connected above the lower tooth plate 233. When the second driven tooth 261 rises to contact with the upper tooth plate 234, it will drive the second driven tooth 261 and the second rotating rod 26 to rotate clockwise. The diameter of the second driven tooth 261 is larger than the diameter of the first driven tooth 252, avoiding the upper tooth plate 234 from being on the upper tooth plate When the pump 24 pumps water, the water level drops, and when the second rotating rod 26 rotates counterclockwise, the valve handle of the butterfly valve 34 will be driven to rotate and gradually open, thereby realizing intermittent steam supply, reducing steam consumption, and improving energy saving.

[0064] See also Figure 9 As shown, in this embodiment, the tube structure 21 includes a preheating tube 211, a first heating tube 212 and a second heating tube 213. The front end of the preheating tube 211 passes through the front side wall of the condensation water pool 16 and is connected to the external water inlet, the middle section is in the shape of a serpentine tube and is located in the preheating compartment 17, and the rear end passes through the rear side wall of the preheating compartment 17 and is connected to the bottom end of the first heating tube 212. The middle section of the first heating tube 212 is in the shape of a serpentine tube and is arranged in the left side box 13, and the top end is connected to the top end of the second heating tube 213. The middle section of the second heating tube 213 is in the shape of a serpentine tube and is arranged in the right side box 13, and the bottom end passes through the right side box 13 and is connected to the external water outlet. The setting of the serpentine tube prolongs the flow time of cold water in the preheating stage and the subsequent heating stage, thereby ensuring the effect of heat exchange.

[0065] See also Figure 6 and Figure 10 As shown, in this embodiment, the inner bottom surface of the side box 13 is inclined with a low inner side and a high outer side. When the high-temperature condensed water falling from the first heating tube 212 and the second heating tube 213 falls on the bottom surface of the side box 13, the inclined bottom surface can quickly send the condensed water to the preheating compartment 17 to avoid condensed water residue. A spring plate 27 is fixed to the inner bottom surface of the side box 13. A horizontal convex rib 271 is fixed to the top of the inner wall of the spring plate 27. A knocking head 272 is fixed to the inner wall of the spring plate 27 in a matrix-shaped regular distribution. The knocking head 272 is opposite to the middle section of the first heating tube 212 and the middle section of the second heating tube 213. In response, the outer end of the first rotating rod 251 rises into the corresponding side box 13, and a top block 255 is fixed at the edge of the outer end face of the first rotating rod 251. The top block 255 is adapted to the height of the corresponding side rib 271. When the first rotating rod 251 rotates, it drives the top block 255 to rotate synchronously and continuously push the rib 271 outward. When the top block 255 leaves the rib 271, the elasticity of the spring plate 27 itself will drive the knocking head 272 to gently knock the first heating tube 212 and the second heating tube 213, so that the high-temperature condensed water attached to the first heating tube 212 and the second heating tube 213 falls quickly to avoid affecting the heating.

[0066] The working principle of the energy-saving steam curing pool heat exchange device for cement pole production in the present invention is as follows:

[0067] When steam curing a cement pole, the cement pole is hoisted to the placement rack 14, and then the sealing door 12 is closed and the external steam generating device is started, so that steam enters from the steam inlet pipe 31 and is ejected from the steam nozzle 32;

[0068] As the curing process progresses, high-temperature condensed water is gradually generated inside the cell body 11. The high-temperature condensed water enters the preheating compartment 17 under the action of its own gravity and the guidance of the partition plate 15. At this time, the cold water introduced for heat exchange first enters the preheating pipe 211 and is preheated in the water bath of the high-temperature condensed water. Then, it enters the first heating pipe 212 and the second heating pipe 213 in sequence for heating.

[0069] As steam is introduced, high-temperature condensate gradually increases, causing the float 222 and the float plate 221 to drive the transmission plate 232 upward. When the lower tooth plate 233 rises and contacts the first driven tooth 252, it drives the first rotating rod 251 to rotate, thereby driving the inner bevel gear 253 to rotate, and the rotating ring 33 to rotate through the bevel tooth surface 333, causing the inner gear block 331 and the third driven tooth 321 to rotate, driving the two steam nozzles 32 to swing, making the steam spray more uniform and avoiding the situation where the local curing temperature is too high.

[0070] When the float 222 and the float plate 221 continue to rise until the second driven tooth 261 contacts the upper tooth plate 234, it will drive the second driven tooth 261 and the second rotating rod 26 to rotate clockwise, driving the valve handle of the butterfly valve 34 to rotate and gradually close. When the high-temperature condensate water level rises to trigger the pump 24 to shut down, as the pumping water level of the pump 24 drops, the second rotating rod 26 will rotate counterclockwise, driving the valve handle of the butterfly valve 34 to rotate and gradually open, thereby realizing intermittent steam delivery, reducing steam consumption, and improving energy saving effects.
