Description

Technical Field

[0001] This utility model relates to the field of large-diameter tube segment maintenance technology, specifically a steam curing temperature control device for large-diameter tube segment independent kilns. Background Technology

[0002] Large-diameter tunnel segments are precast concrete components used in tunnel engineering. They are suitable for arc-shaped or ring-shaped assembled structural components for large-section tunnels. The large-diameter tunnel segment independent kiln steam curing temperature control device is specially designed for large-diameter tunnel segments. It is installed in an independent curing kiln and is a special equipment to ensure the curing quality of tunnel segments through steam heating and precise temperature control.

[0003] When large-diameter tube segments are steam cured in an independent kiln, the high-temperature steam inside the kiln comes into contact with the low-temperature kiln top and easily condenses into water droplets. These condensed water droplets fall vertically onto the surface of the tube segments, causing a sudden drop in local temperature and generating temperature stress, which in turn leads to cracks and defects, affecting the structural strength and waterproof performance of the tube segments.

[0004] Therefore, a large-diameter segmental independent kiln steam curing temperature control device is needed to solve the above problems by centrally collecting condensate in the kiln to optimize the steam curing effect of the independent kiln. Utility Model Content

[0005] The purpose of this invention is to provide a steam curing temperature control device for large-diameter segmental kilns to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steam curing temperature control device for a large-diameter segmental kiln, comprising an independent kiln body, wherein the top of the independent kiln body is provided with a kiln roof; A water scraping unit is placed inside the kiln roof. The water scraping unit includes a water scraping component and a collection component. The water scraping component is used to scrape off the condensate on the kiln roof, and the collection component is used to collect and discharge the scraped condensate. The humidity control unit is located outside the scraper unit. It is used to treat and re-spray the collected condensate to regulate the humidity inside the independent kiln. Under the restriction of the scraper unit, it can prevent condensate from dripping onto the large-diameter tubes and causing defects and damage to the tubes. Under the restriction of the humidity control unit, the collected condensate can be recycled and the humidity inside the independent kiln can be adjusted according to the needs.

[0007] Preferably, the wiper assembly includes a mounting plate, a motor is connected to the side wall of the mounting plate, a reciprocating screw is connected to the output end of the motor, a rod sleeve is fitted on the outer wall of the reciprocating screw, a wiper blade is connected to the outer wall of the rod sleeve, a limit sleeve is connected to the end of the wiper blade away from the rod sleeve, and a limit rod is fitted inside the limit sleeve.

[0008] Preferably, the collecting assembly includes a frame, a collecting hopper connected to the end of the frame, a sliding sleeve connected to the outer wall of the collecting hopper, a sliding rod slidably connected inside the sliding sleeve, a sealing plate connected to the end of the sliding rod, a spring sleeved on the outer wall of the sliding rod, and an extrusion plate connected to the bottom of the kiln top.

[0009] Preferably, the top surface of the sealing plate is sealed to the inside of the collection hopper, and the end of the slide rod away from the sealing plate slides and presses against the inclined surface of the extrusion plate. Under the restriction of the extrusion plate, the slide rod pushes the sealing plate so that the sealing plate no longer blocks the bottom of the collection hopper.

[0010] Preferably, the scraper is slidably disposed with respect to the bottom of the kiln roof, and the scraper is made of rubber. Under its constraint, the sliding scraper can be prevented from scratching the kiln roof.

[0011] Preferably, the humidity control unit includes a water storage tank, the bottom surface of which is provided with a filter adsorption plate, a connecting pipe is connected to the bottom of the water storage tank, a pump body is connected to the end of the connecting pipe, a delivery pipe is connected to the bottom of the pump body, and a spray plate is connected to the end of the delivery pipe away from the pump body.

[0012] Preferably, the filter adsorption plate is provided with adsorption cotton inside, and the filter adsorption plate is sleeved on the bottom surface of the water storage tank. Under the restriction of the filter adsorption plate, the delivered condensate can be optimized.

[0013] Preferably, there are two spray plates symmetrically distributed around the center line of the independent kiln. Under the constraint of the two spray plates, the treated condensate can be sprayed to regulate the humidity inside the independent kiln.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the starting motor drives the reciprocating screw to rotate, and the scraper slides against the kiln top under the constraint of the limiting rod to scrape away the condensate. The collection hopper moves synchronously with the scraper. When the scraper reaches the edge of the kiln top, the sliding rod is driven by the squeezing plate to open the sealing plate, and the condensate is discharged to the humidity regulating unit. After the squeezing is released, the sealing plate is reset by the spring to prevent the condensate from dripping and damaging the tube plates. 2. In this invention, the collected condensate is transported to a storage tank for storage. When it is necessary to adjust the humidity inside the kiln, the pump body sends the stored water to the spray plate via connecting pipes and delivery pipes. The condensate is then treated by a filter adsorption plate and recycled for reuse, thus precisely controlling the humidity inside the kiln. Attached Figure Description

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a steam curing temperature control device for a large-diameter segmental kiln, including an independent kiln body 1, and a kiln top 2 is provided on the top of the independent kiln body 1. The water scraping unit 3 is located inside the kiln top 2. The water scraping unit 3 includes a water scraping assembly and a collection assembly. The water scraping assembly is used to scrape off the condensate on the kiln top 2, and the collection assembly is used to collect and discharge the scraped condensate. Humidity control unit 4 is located outside the scraper unit 3. The humidity control unit 4 is used to treat and re-spray the collected condensate in order to regulate the humidity inside the independent kiln body 1.

[0024] Under the constraint of the scraper unit 3, the condensate on the kiln top 2 can be prevented from dripping onto the large-diameter tube segments, which would cause defects and damage to the tube segments. Under the constraint of the humidity control unit 4, the collected condensate can be recycled, and the humidity inside the independent kiln body 1 can be adjusted according to the needs.

[0025] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The wiper assembly includes a mounting plate 31, a motor 32 connected to the side wall of the mounting plate 31, a reciprocating screw 33 connected to the output end of the motor 32, a rod sleeve 34 sleeved on the outer wall of the reciprocating screw 33, a wiper blade 35 connected to the outer wall of the rod sleeve 34, a limit sleeve 36 connected to the end of the wiper blade 35 away from the rod sleeve 34, and a limit rod 37 sleeved inside the limit sleeve 36. The collection assembly includes a frame 38, a collection hopper 39 connected to the end of the frame 38, a sliding sleeve 310 connected to the outer wall of the collection hopper 39, a sliding rod 311 slidably connected inside the sliding sleeve 310, a sealing plate 312 connected to the end of the sliding rod 311, a spring 313 sleeved on the outer wall of the sliding rod 311, and an extrusion plate 314 connected to the bottom of the kiln top 2.

[0026] The top surface of the sealing plate 312 is sealed to the inside of the collection hopper 39. The end of the slide rod 311 away from the sealing plate 312 slides and presses against the inclined surface of the extrusion plate 314. Under the restriction of the extrusion plate 314, the slide rod 311 pushes the sealing plate 312 so that the sealing plate 312 no longer seals the bottom of the collection hopper 39.

[0027] Among them, the scraper 35 is slidably set with the bottom of the kiln top 2. The scraper 35 is made of rubber, which can prevent the sliding scraper 35 from scratching the kiln top 2.

[0028] When curing large-diameter tube segments, they are placed inside an independent kiln 1 for steam curing. During curing, condensate easily accumulates on the kiln top 2, which needs to be scraped and cleaned to prevent condensate from dripping onto the large-diameter tube segments and causing damage. At this time, the motor 32 is started, and the reciprocating screw 33 fixedly installed at its output end rotates accordingly. Since the limiting sleeve 36 fixedly installed at the end of the scraper 35 is slidably connected to the outer wall of the limiting rod 37 fixedly installed inside the kiln top 2, under its restriction, the rotating reciprocating screw 33 can drive the scraper 35 to slide against the bottom of the kiln top 2 through the rod sleeve 34, scraping and cleaning the condensate above, and collecting it through the collection hopper. The condensate collection hopper 39 is constructed using a 39-pair system. When the scraper 35 moves, it drives the collection hopper 39 to move along with it via the connecting frame 38. When the scraper 35 reaches the edge of the kiln roof 2, the end of the slide rod 311 slides and presses against the inclined surface of the extrusion plate 314. At this time, the slide rod 311 drives the sealing plate 312 to slide away from the collection hopper 39, and in conjunction with the sliding sleeve 310, it compresses the spring 313, thus discharging the condensate collected inside the collection hopper 39 and storing it through the humidity control unit 4. When the slide rod 311 is no longer compressed, the elasticity of the spring 313 pushes the slide rod 311 back to its original position, resetting the sealing plate 312. This structure can clean the condensate adhering to the kiln roof 2, optimizing the maintenance effect of large-diameter tube segments.

[0029] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The humidity control unit 4 includes a water storage tank 41. The bottom surface of the water storage tank 41 is provided with a filter adsorption plate 42. The bottom of the water storage tank 41 is connected to a connecting pipe 43. The end of the connecting pipe 43 is connected to a pump body 44. The bottom of the pump body 44 is connected to a delivery pipe 45. The end of the delivery pipe 45 away from the pump body 44 is connected to a spray plate 46.

[0030] The filter adsorption plate 42 is equipped with adsorption cotton inside and is fitted inside the bottom surface of the water storage tank 41. Under the restriction of the filter adsorption plate 42, the delivered condensate can be optimized.

[0031] There are two spray plates 46, which are symmetrically distributed around the center line of the independent kiln body 1. Under the restriction of the two spray plates 46, the treated condensate can be sprayed to regulate the humidity inside the independent kiln body 1.

[0032] After the scraper unit 3 cleans the condensate, it is transported to the water storage tank 41 through the collection component and stored in the water storage tank 41. When it is necessary to adjust the humidity inside the independent kiln body 1, the pump body 44 transports the condensate inside the water storage tank 41 to the conveying pipe 45 and the spray plate 46 through the connecting pipe 43, so as to regulate the humidity inside the independent kiln body 1. Under the filtration and adsorption limitation of the filter adsorption plate 42, the condensate can be treated and circulated for use in regulating the humidity inside the independent kiln body 1.

[0033] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0034] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
