Description

Technical Field

[0001] This invention relates to the field of concrete forming technology, and in particular to an energy-saving curing device for precast concrete building components. Background Technology

[0002] Precast concrete components are concrete structures that are pre-cast into shape using molds in a factory or on-site, and then cured to reach their required strength. After pouring, the cement needs to undergo a hydration reaction with water to gradually harden and develop strength. Therefore, a scientific and uniform curing process is crucial to determining the final mechanical properties and durability of the precast components. Currently, the industry typically uses steam curing chambers for high-temperature and high-humidity steam curing to accelerate the hydration process and shorten the production cycle.

[0003] During steam curing, high-temperature saturated steam fills the interior of the curing chamber, while the temperature of the inner wall at the top of the chamber is relatively low. When the high-temperature steam comes into contact with the cold top wall, it liquefies to form a large number of condensed water droplets. These tiny water droplets continuously gather and grow, eventually dripping onto the top surface of the precast concrete component below under the influence of gravity. When the top surface of the precast component becomes too wet due to water accumulation, it can easily lead to inconsistent hydration levels between the top and sides of the component, resulting in uneven overall strength distribution and affecting the curing quality of the precast component. On the other hand, most existing steam injection systems in steam curing equipment use fixed nozzles, and their injection angle, coverage area, and distance are not easily dynamically adjusted. Because the injection range is fixed, the steam flow often concentrates and blows directly onto a specific area of ​​the component for a long time, which can easily lead to differences in steam and temperature in some areas, thereby reducing the curing effect.

[0004] Therefore, this application provides an energy-saving curing device for precast concrete building components to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an energy-saving curing equipment for precast concrete building components, so as to solve the problems that the dripping of condensate from the top of the existing steam curing chamber can easily affect the curing quality, resulting in uneven strength distribution of the components, and that the fixed nozzles are not easy to dynamically adjust the spray range, which can easily cause curing blind spots and local direct blowing, thus reducing curing efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An energy-saving curing device for precast concrete building components includes: a curing chamber, a curing conveying mechanism slidably mounted on the chamber via a bottom slide rail, a screw connected to a groove on the top of the curing chamber via a motor, a connecting block threadedly connected to the outside of the screw, the connecting block sliding within the groove on the top of the curing chamber, a water removal component at the bottom of the connecting block for cleaning condensate, multiple fixed frames fixedly connected at equal intervals on both sides of the curing chamber, mounting frames connected to the bottom of the multiple fixed frames via springs, the mounting frames sliding within the slotted holes on both sides of the fixed frames via protrusions on both sides, a connecting pipe rotatably mounted at the center of two protrusions on the side of the mounting frame away from the fixed frame, multiple nozzles mounted on one side of the connecting pipe, and the other end of the connecting pipe connected to an external steam generating mechanism via a hose, an adjusting component between the fixed frames and the connecting pipe for adjusting the position of the connecting pipe.

[0007] Optionally, the dewatering component includes a scraper, which is fixedly installed at the bottom of the connecting block. A water guide plate is fixedly connected to the bottom of the scraper, and the top of the scraper abuts against the top of the steam curing chamber.

[0008] Optionally, the side wall of the scraper near the guide plate is set as an inclined surface, which is used to guide the scraped condensate to slide onto the guide plate. The bottom inner side of the guide plate is designed with an arched protrusion structure, which is used to guide the condensate to fall.

[0009] Optionally, a connecting seat is installed at the bottom of the water guide plate via an electric push rod, and a cleaning soft brush is connected to the inner side of the connecting seat via a motor.

[0010] Optionally, a fixing plate is fixedly connected to the bottom of the connecting block, and abutment plates are provided oppositely in the mounting grooves on both sides of the fixing plate. The adjusting component includes a sliding plate, one end of which slides against the abutment plate, and the other end of which is connected to a fixing seat via a spring. The sliding plate slides in a limited manner with the bottom groove of the fixing seat via a top slider. The fixing seat is fixed to the top of the mounting frame. A rack is installed on one side of the bottom of the sliding plate, and a gear is meshed with the rack teeth. The gear is fixedly connected to the outside of the upper shaft of the connecting pipe.

[0011] Optionally, a second abutment is fixedly connected to the top of the first abutment, and a second sliding plate is fixedly connected to the top of the fixed base, wherein the second abutment and the second sliding plate slide against each other.

[0012] Optionally, the outer side of the first contact plate is designed as an arc-shaped surface, and the arc-shaped surface of the first contact plate is used for the sliding adjustment of the position of the first sliding plate. The bottom surface of the second contact plate is designed as a sloping arc-shaped surface, and the sloping arc-shaped surface of the second contact plate is used for the sliding adjustment of the position of the second sliding plate.

[0013] Optionally, the maximum downward movement distance of the second contact plate against the second sliding plate corresponds to the vertical height of the first contact plate.

[0014] Optionally, the inner wall of the inner groove of the fixed plate is slidably connected to a support plate by means of an electric push rod, and the support plate is fixedly connected to both the first and second contact plates.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a water removal component and a cleaning soft brush, the motor drives the screw to drive the connecting block to reciprocate, so that the scraper physically removes the condensate on the top of the steam curing chamber. The water flow is quickly collected and discharged by the arched water guide plate with a central convex and two concave sides, preventing the condensate formed by the liquefaction of high-temperature steam from dripping and impacting the surface of the precast concrete. This reduces quality defects such as pitting, color difference and uneven strength caused by local temperature difference and water washing. After the concrete has initially set, the connecting seat is lowered by the electric push rod, so that the cleaning soft brush contacts the top of the precast concrete. While the cleaning soft brush moves with the connecting block, it rotates under the action of the motor, gently sweeping the water on the top of the precast concrete to reduce the water residue on the top of the precast concrete, thereby improving the steam curing effect and enhancing the appearance quality and surface strength consistency of the precast concrete.

[0016] In the above scheme, by setting an adjustment component, when the connecting block moves, it drives the first and second contact plates to move horizontally synchronously. Utilizing the outer arc-shaped surface of the first contact plate and the bottom sloping arc-shaped surface of the second contact plate, the first and second sliding plates move. The movement of the first sliding plate drives the rack to move, thereby driving the gear and connecting pipe to rotate, thus expanding the spray angle of the nozzle. The movement of the second sliding plate causes the entire connecting pipe to move vertically, thereby expanding the vertical spray uniformity of the nozzle. This allows the connecting pipe to change the vertical spray range while changing the spray angle, reducing curing dead angles and improving curing uniformity. The electric push rod drives the support plate to move within the fixed plate, changing the initial contact point and maximum pushing distance of the first and second contact plates relative to the first and second sliding plates, thus facilitating the expansion of the maximum rotation angle and maximum descent depth of the connecting pipe, further expanding the nozzle spray range and ensuring uniform steam distribution.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] like Figures 1 to 10As shown, an embodiment of the present invention provides an energy-saving curing device for precast concrete building components, comprising: a curing chamber 1, a curing conveying mechanism 2 slidably mounted on the curing chamber 1 via a bottom slide rail, a screw 3 connected to a groove at the top of the curing chamber 1 via a motor, a connecting block 4 threadedly connected to the outside of the screw 3, the connecting block 4 sliding within the groove at the top of the curing chamber 1, a water removal component 5 provided at the bottom of the connecting block 4 for cleaning condensate, and multiple fixing frames 6 fixedly connected at equal intervals to both side walls of the curing chamber 1, the bottom of the multiple fixing frames 6 being connected to mounting frames 7 via springs, the mounting frames 7 sliding within the slotted holes on both sides of the fixing frames 6 via protrusions on both sides, and the mounting frames 7 being located away from... A connecting pipe 8 is rotatably installed at the center of two protruding plates on one side of the fixed frame 6. Multiple nozzles are installed on one side of the connecting pipe 8, and the other end of the connecting pipe 8 is connected to an external steam generator through a hose. An adjustment component 9 is provided between the fixed frame 6 and the connecting pipe 8. The adjustment component 9 is used to adjust the position of the connecting pipe 8. The top of the steam curing conveying mechanism 2 is used to place the precast concrete component. The steam curing conveying mechanism 2 facilitates the delivery of the precast concrete component into the steam curing chamber 1 for steam curing treatment. During steam curing, the external steam generator produces high-temperature steam, which is delivered to the connecting pipe 8 through a hose and finally sprayed out from multiple nozzles installed on one side of the connecting pipe 8 to steam cure the precast concrete component.

[0021] The water removal component 5 includes a scraper 51, which is fixedly installed at the bottom of the connecting block 4. A water guide plate 52 is fixedly connected to the bottom of the scraper 51, and the top of the scraper 51 abuts against the top of the steam curing chamber 1. During the steam curing process, the high-temperature steam encounters the cooler inner wall of the top of the steam curing chamber 1 and liquefies to form condensate droplets. The motor drives the screw 3 to rotate back and forth, thereby driving the connecting block 4 to move back and forth in a straight line along the axis of the screw 3 in the groove at the top of the steam curing chamber 1. The scraper 51 fixed at the bottom of the connecting block 4 moves accordingly, and the top of the scraper 51 abuts against the top of the steam curing chamber 1. The condensate adhering to the top of the steam curing chamber 1 is scraped off by physical contact, preventing it from accumulating into large water droplets. The scraped water flows into the water guide plate 52 fixedly connected to the bottom of the scraper 51, reducing the problem of localized strength reduction on the surface of the precast concrete due to condensate dripping.

[0022] The side wall of the scraper 51 near the water guide plate 52 is set as an inclined surface. The inclined surface is used to guide the scraped condensate to slide onto the water guide plate 52. The bottom inner side of the water guide plate 52 is designed with an arched protrusion structure. The arched protrusion structure at the bottom inner side of the water guide plate 52 is used to guide the condensate to fall. Since the side wall of the scraper 51 near the water guide plate 52 is set as an inclined surface, the water flow scraped by the scraper 51 flows into the water guide plate 52. After the water flow falls on the water guide plate 52, due to the arched protrusion structure at the bottom inner side of the water guide plate 52, the water droplets falling in the middle area of ​​the water guide plate 52 will quickly converge into both sides of the water guide plate 52 and fall down. The water droplets fall into the bottom of the steam curing chamber 1 for easy collection and discharge to the outside.

[0023] A connecting seat 10 is installed at the bottom of the water guide plate 52 via an electric push rod. A cleaning soft brush 11 is connected to the inner side of the connecting seat 10 via a motor. When the precast concrete component is first placed in the steam curing chamber 1, it is in the initial setting state and the surface is relatively fragile. At this time, the electric push rod retracts, raising the connecting seat 10 and the cleaning soft brush 11 to a high position, so that the cleaning soft brush 11 is away from the top of the precast concrete component to avoid contact damage. At this time, only the scraper 51 and the water guide plate 52 are working. After a period of steam curing, the surface of the precast concrete component has initially solidified and has a certain strength. The electric push rod is activated, pushing the connecting seat 10 downward until the bristles of the cleaning soft brush 11 contact the top of the precast concrete component. At this time, the scraper 51 and the water guide plate 52 drive the cleaning soft brush 11 to move along the top of the precast concrete component, and the cleaning soft brush 11 rotates under the drive of the motor, which facilitates the sweeping of water droplets on the top of the precast concrete component.

[0024] A fixing plate 12 is fixedly connected to the bottom of the connecting block 4. Abutment plates 13 are oppositely arranged in the mounting grooves on both sides of the fixing plate 12. The adjusting assembly 9 includes a sliding plate 91. One end of the sliding plate 91 slides against the abutment plates 13, and the other end of the sliding plate 91 is connected to a fixing seat 92 via a spring. The sliding plate 91 is limited to sliding against the bottom groove of the fixing seat 92 by a top slider. The fixing seat 92 is fixed to the top of the mounting bracket 7. A rack 93 is installed on one side of the bottom of the sliding plate 91. A gear 94 is meshed with the teeth of the rack 93. The gear 94 is fixedly connected to the outer side of the upper shaft of the connecting pipe 8. When the screw 3 rotates, causing the connecting block 4 to move horizontally along the groove at the top of the steam chamber 1, the fixing plate 12 fixed to the bottom of the connecting block 4 moves accordingly, causing the abutment plates 13 in the mounting grooves on both sides of the fixing plate 12 to move. 13. When the contact plate 13 contacts the sliding plate 91, it overcomes the spring resistance and pushes the sliding plate 91 to slide horizontally in the groove of the fixed seat 92. The movement of the sliding plate 91 drives the rack 93 to move horizontally as well. The rack 93 meshes with the gear 94 fixed on the outside of the connecting pipe 8, converting the linear motion of the rack 93 into the rotational motion of the gear 94. The gear 94 drives the connecting pipe 8 to rotate, thereby changing the spray angle of the nozzle to improve the uniformity of steam curing. When the contact plate 13 passes the sliding plate 91, the pushing force of the contact plate 13 on the sliding plate 91 disappears. At this time, under the action of the spring, the sliding plate 91 is pushed to slide back to its original position. The reset of the sliding plate 91 drives the rack 93 to retract, thereby driving the gear 94 and the connecting pipe 8 to rotate in the opposite direction, so that the nozzle returns to the initial angle.

[0025] A second contact plate 14 is fixedly connected to the top of the first contact plate 13, and a second sliding plate 95 is fixedly connected to the top of the fixed base 92. The second contact plate 14 and the second sliding plate 95 slide against each other. When the first contact plate 13 moves, it drives the second contact plate 14 to move synchronously. When the second contact plate 14 moves, it contacts and pushes the second sliding plate 95 fixed to the top of the fixed base 92. The thrust of the second contact plate 14 forces the second sliding plate 95 to move downward. The downward movement of the second sliding plate 95 drives the fixed base 92 and the mounting bracket 7 to move downward, thereby driving the connecting pipe 8 to move downward, expanding the vertical spray range of the nozzle and improving the steam curing effect. When the second contact plate 14 disengages from the second sliding plate 95, the mounting bracket 7 resets under the action of the bottom spring, thereby driving the fixed base 92 and the connecting pipe 8 to rise back to the initial height.

[0026] The outer side of the first contact plate 13 is designed as an arc surface, which is used for the sliding adjustment of the position of the first sliding plate 91. The bottom surface of the second contact plate 14 is designed as a sloping arc surface, which is used for the sliding adjustment of the position of the second sliding plate 95. When the connecting block 4 drives the fixed plate 12 to move, the outer arc surface of the first contact plate 13 first contacts the first sliding plate 91. As the horizontal displacement of the connecting block 4 increases, the thrust component of the sloping arc surface of the first contact plate 13 on the first sliding plate 91 gradually increases, thereby causing the connecting pipe 8 and the nozzle to rotate continuously. At the same time, the second contact plate 14 contacts the second sliding plate 95 with its bottom sloping arc surface. As the second contact plate 14 moves forward, the sloping arc surface of the second contact plate 14 slowly presses down the second sliding plate 95, thereby causing the height of the connecting pipe 8 and the nozzle to decrease.

[0027] The maximum downward movement distance of the second contact plate 14 against the second sliding plate 95 corresponds to the vertical height of the first contact plate 13.

[0028] A support plate 15 is slidably connected to the inner wall of the inner groove of the fixed plate 12 via an electric push rod. The support plate 15 is fixedly connected to the first contact plate 13 and the second contact plate 14. When the electric push rod is started, it drives the support plate 15 to move. The movement of the support plate 15 directly causes the first contact plate 13 and the second contact plate 14 to move, thereby changing the initial contact point and the maximum pushing distance of the first contact plate 13 and the second contact plate 14 relative to the first sliding plate 91 and the second sliding plate 95. During the initial steam curing, when steam needs to be quickly filled into the steam curing chamber 1, when the first contact plate 13 is pushed away from the inner groove of the fixed plate 12, the first contact plate 13 pushes the first sliding plate 91 to move a longer distance, thereby significantly expanding the rotation angle range of the connecting pipe 8. At the same time, the second contact plate 14 pushes the second sliding plate 95 to descend to a deeper height, causing the connecting pipe 8 to descend to a deeper height, further expanding the spray range of the nozzle.

[0029] The working principle of the technical solution provided by this invention is as follows: During the use of this device, the precast concrete component is placed on top of the steam curing conveying mechanism 2. The steam curing conveying mechanism 2 is started, and the precast concrete component that has just been poured and is in the initial setting state is steadily sent into the steam curing chamber 1. During steam curing, the external steam generating mechanism generates high-temperature steam. The high-temperature steam is transported to the connecting pipe 8 through the hose, and finally sprayed out from multiple nozzles installed on one side of the connecting pipe 8 to perform steam curing treatment on the precast concrete component. During the steam curing process, the high-temperature steam encounters the cooler inner wall of the top of the steam curing chamber 1, liquefying to form condensation droplets. The motor drives the screw 3 to rotate reciprocally, causing the connecting block 4 to move reciprocally in a straight line along the groove at the top of the steam curing chamber 1. The top of the scraper 51, fixed to the bottom of the connecting block 4, abuts against the top wall of the steam curing chamber 1, physically scraping away the condensation droplets formed by the temperature difference, preventing them from accumulating into large droplets that drip directly, thus affecting the steam curing effect of the precast concrete. The scraped water flows down the inclined surface of the scraper 51 into the water guide plate 52. Because the bottom inner side of the water guide plate 52 is designed with an arched protrusion structure, the water falls into the water guide plate. Water droplets in the middle area of ​​plate 52 will quickly flow into both sides of the water guide plate 52 and fall down. The water droplets fall into the bottom of the steam curing chamber 1 for easy collection and discharge to the outside. When the steam curing has been carried out for a certain period of time and the surface of the precast concrete has initially solidified and gained strength, the connecting seat 10 is lowered by the electric push rod so that the cleaning soft brush 11 contacts the top of the precast concrete. At this time, the scraper 51 and the water guide plate 52 drive the cleaning soft brush 11 to move along the top of the precast concrete. While the cleaning soft brush 11 moves with the connecting block 4, the motor is started so that the motor drives the cleaning soft brush 11 to rotate to sweep away the water droplets on the top of the precast concrete. When the connecting block 4 moves, it drives the fixed plate 12 to move, thereby causing the first contact plate 13 and the second contact plate 14 to move horizontally synchronously. During the movement of the first contact plate 13, the outer arc-shaped surface of the first contact plate 13 smoothly contacts the first sliding plate 91. As the horizontal displacement of the first contact plate 13 increases, the arc-shaped surface of the first contact plate 13 pushes the first sliding plate 91 to overcome the spring resistance and slide horizontally. The movement of the first sliding plate 91 drives the rack 93 to move, which in turn drives the gear 94 and the connecting pipe 8 to rotate, thereby expanding the spray angle of the nozzle. At the same time, the bottom sloping arc-shaped surface of the second contact plate 14 synchronously contacts the second sliding plate 95. As the second contact plate 14 moves, the second contact plate 95... The sloping arc surface of 14 slowly presses down the sliding plate 2 95, thereby driving the fixed seat 92, the mounting bracket 7 and the connecting pipe 8 to descend vertically as a whole, expanding the vertical spraying range of the nozzle, improving the steam curing effect, and changing the vertical spraying range of the nozzle while changing the spraying angle, thus improving the steam curing uniformity of the precast concrete. After the first contact plate 13 and the second contact plate 2 14 pass over the first sliding plate 91 and the second sliding plate 2 95, the thrust of the first contact plate 13 and the second contact plate 2 14 disappears. Under the action of the spring, the first sliding plate 91 and the second sliding plate 2 95 smoothly reset, driving the nozzle angle back to the center, and the nozzle angle rises again, preparing for the next reciprocating cycle. During the initial steam curing process, when steam is needed to quickly fill the curing chamber 1, and when it is necessary to further expand the spray range of the nozzles, the support plate 15 is moved by the electric push rod. The movement of the support plate 15 directly causes the first contact plate 13 and the second contact plate 14 to shift, pushing the first contact plate 13 away from the inner groove of the fixed plate 12. The first contact plate 13 will push the first sliding plate 91 to move a longer distance, thereby significantly expanding the rotation angle range of the connecting pipe 8. At the same time, the second contact plate 14 pushes the second sliding plate 95 to descend to a deeper height, causing the connecting pipe 8 to descend to a deeper height. At this time, the humidity inside the curing chamber 1 will increase. The motor is synchronously controlled to increase the speed of the screw 3, so that the scraper 51 and the cleaning soft brush 11 can clean the condensate more frequently. After the steam curing is completed, the precast concrete is transported out of the curing chamber 1 by the steam curing conveying mechanism 2.
