[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A rapid drying structure for prefabricated component processing includes a drying chamber 1, a support frame 2 is installed inside the drying chamber 1, a placement frame 3 is provided on the top of the support frame 2, a uniform drying mechanism 4 is provided inside the drying chamber 1, and a ventilation mechanism 5 is provided on the side wall of the drying chamber 1;

[0031] The uniform drying mechanism 4 includes a first electric push rod 41, a connecting rod 42, a mounting frame 43, a first electric heating wire 44, a mounting seat 45 and a blowing fan 46. Two groups of first electric push rods 41 are bolted to the side wall of the drying chamber 1, the connecting rod 42 is fixedly connected to the output end of the first electric push rod 41, the mounting frame 43 is fixedly connected to the side walls of the two connecting rods 42, multiple first electric heating wires 44 are arranged in the middle of the mounting frame 43, the mounting seat 45 is fixedly connected to the side wall of the mounting frame 43, and three groups of blowing fans 46 are bolted to the middle of the mounting seat 45.

[0032] Specifically, such as Figure 3 As shown, a sliding frame 6 is installed on both side walls of the drying chamber 1 , and two sliding blocks 7 are installed on both side walls of the installation frame 43 . The sliding blocks 7 are movably arranged inside the sliding frame 6 .

[0033] Specifically, such as Figure 5 As shown, a slide groove 11 is opened on the side wall of the support frame 2 , and a support pulley 12 is bolted to the bottom of the placement frame 3 , and the support pulley 12 is movably arranged inside the slide groove 11 .

[0034] Specifically, such as Figure 5 As shown, a sealing door 13 is slidably provided on the side wall of the drying chamber 1 , and a third electric push rod 14 is bolted to both side walls of the drying chamber 1 , and the output end of the third electric push rod 14 is fixedly connected to the sealing door 13 .

[0035] Specifically, such as Figure 5 As shown, a transparent observation window 15 is provided in the middle of the sealing door 13 .

[0036] During use, the placement frame 3 is used to support the placement of concrete components. After the placement frame 3 and the concrete components are placed into the drying chamber 1, the third electric push rod 14 pulls the sealing door 13 to close the drying chamber 1, and the first electric heating wire 44 generates heat to dry the front and back sides of the concrete components at the same time. The blowing fan 46 blows hot air to the concrete components, so that the hot air covers the concrete components, thereby improving the drying efficiency of the concrete components. At the same time, the first electric push rod 41 pushes and pulls the installation frame 43 back and forth to move, thereby realizing a mobile circular drying operation of the concrete, so that all positions of the concrete components are evenly dried.

[0037] Specifically, such as Figure 4 As shown, the ventilation mechanism 5 includes a ventilation hood 51, a ventilation pipe 52, an air inlet pipe 53, an exhaust pipe 54, an air intake fan 55, a second electric heating wire 56 and an exhaust fan 57. Two groups of ventilation hoods 51 are respectively arranged on the two side walls of the drying chamber 1, four groups of ventilation pipes 52 are arranged on the side walls of the ventilation hood 51 and are connected with the drying chamber 1, the air inlet pipe 53 and the exhaust pipe 54 are respectively arranged on the side walls of the ventilation hood 51, the air inlet pipe 53 is located at the bottom of the drying chamber 1, the air intake fan 55 is bolted to the inside of the air inlet pipe 53, the second electric heating wire 56 is arranged inside the air inlet pipe 53, and the exhaust pipe 54 is arranged inside the exhaust pipe 54.

[0038] Specifically, such as Figure 4 As shown, a second electric push rod 8 is bolted to the side wall of the ventilation cover 51 , and a blocking block 9 is installed at the output end of the second electric push rod 8 , and the blocking block 9 is movably arranged inside the ventilation cover 51 .

[0039] Specifically, such as Figure 4 As shown, a metal filter 10 is bolted to one end of the air inlet pipe 53 .

[0040] During use, after drying the concrete components, moisture is generated inside the drying chamber 1. At this point, the exhaust fan 57 is activated, extracting the moisture from the drying chamber 1 through the ventilation hood 51 and ventilation duct 52. Simultaneously, the intake fan 55 is activated to deliver air into the air inlet duct 53. The second electric heating wire 56 heats the air inside the air inlet duct 53, heating the air entering the drying chamber 1 through the ventilation hood 51 and ventilation duct 52. Simultaneously, the second electric push rod 8 pushes and pulls the block 9 to control ventilation of the ventilation hood 51, thereby exhausting moisture from the drying chamber 1 and introducing dry air from outside, thereby achieving ventilation within the drying chamber 1.

[0041] By adopting the above technical solution, the existing drying device cannot dry the front and back sides of the concrete component at the same time, cannot perform mobile circulation drying of the concrete component, and is prone to local cracking when drying in a fixed position for a long time. At the same time, it is unable to ventilate the moisture generated during drying.

[0042] Working principle: When the present application is in use, firstly, the placement frame 3 and the concrete component are placed inside the drying chamber 1, and then the third electric push rod 14 pulls the sealing door 13 to close the drying chamber 1. The first electric heating wire 44 generates heat to dry the front and back sides of the concrete component at the same time, and the blowing fan 46 blows hot air to the concrete component so that the hot air covers the concrete component, thereby improving the drying efficiency of the concrete component. At the same time, the first electric push rod 41 pushes and pulls the mounting frame 43 back and forth to move, thereby realizing a mobile and cyclic drying operation of the concrete, so that each position of the concrete component is evenly dried. At this time, uniform drying of the concrete component is achieved, and moisture is generated inside the drying chamber 1. At this time, the exhaust fan 57 is started to extract the moisture inside the drying chamber 1 through the ventilation hood 51 and the ventilation pipe 52. At the same time, the air intake fan 55 starts to deliver air to the inside of the air inlet pipe 53, and the second electric heating wire 56 heats the air inside the air inlet pipe 53, so that the air entering the drying chamber 1 through the ventilation hood 51 and the ventilation pipe 52 is heated. At the same time, the ventilation of the ventilation hood 51 can be controlled by pushing and pulling the block 9 by the second electric push rod 8, thereby discharging moisture from the drying chamber 1 and introducing external dry air, so that the interior of the drying chamber 1 can be ventilated.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
