[0040] The technical scheme of the utility model will be further illustrated below by combining the drawings and through specific embodiments.

[0041] The embodiment provides a vertical drying equipment, which can occupy a smaller space in the horizontal direction, can reduce the risk of damaging products, and has higher reliability.

[0042] The vertical drying equipment provided by the embodiment is used for drying the coating on the surface of a product, and has good drying effect. For example, the product can be a galvanized steel sheet.

[0043] As shown in Figures 1 to 8 The vertical drying equipment includes a furnace body 100, a heating assembly 200, and a first driving member 300. The height of the furnace body 100 is greater than the length of the furnace body 100 and greater than the width of the furnace body 100, so that the furnace body 100 extends in the vertical direction, that is, the furnace body 100 in the embodiment is a vertical furnace, so as to occupy a smaller space in the horizontal direction. In order to ensure the conveying time of the product in the furnace body 100, in the embodiment, the product is conveyed in the furnace body 100 along the height direction of the furnace body 100, so as to prolong the heating time of the product and ensure the drying effect of the coating on the product.

[0044] For the convenience of description, in the embodiment, the length direction of the furnace body 100 is referred to as a first direction X, the width direction of the furnace body 100 is referred to as a second direction Y, and the height direction of the furnace body 100 is referred to as a third direction Z. Any two of the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The length of the furnace body 100 can be greater than, equal to, or less than the width of the furnace body 100, which is not limited in the embodiment.

[0045] In some optional embodiments, the product is conveyed in the furnace body 100 by a conveying device, which includes but is not limited to a tensioning roller arranged at the inlet and outlet of the furnace body 100. In order to improve the drying efficiency of the product, for example, the vertical furnace, the inlet of the furnace body 100 is located at the bottom of the furnace body 100, and the outlet is located at the top of the furnace body 100. After the product enters the furnace body 100 from the inlet, it is conveyed to the top of the furnace body 100 and then output from the outlet. Exemplarily, the drying equipment provided in the embodiment is a drying furnace, and a cooling furnace is arranged downstream of the drying furnace. The inlet of the cooling furnace is located at the top, and the product output from the top of the furnace body 100 can directly enter the cooling furnace for cooling after reversing.

[0046] The heating assembly 200 in the embodiment is used to release heat and infrared radiation into the furnace body 100, and then dry and heat the products in the furnace body 100. Exemplarily, the heating assembly 200 is adjustably connected to the furnace body 100 along the first direction X, and the heating assembly 200 has a closed position and an open position. The furnace body 100 is provided with a mounting port, when the heating assembly 200 is in the closed position, the heating assembly 200 is sealingly mounted on the mounting port, and the heating surface of the heating assembly 200 faces the inside of the furnace body 100, so that the infrared radiation emitted by the heating assembly 200 can cover the surface of the products in the furnace body 100. When the heating assembly 200 is in the open position, the heating assembly 200 is located outside the furnace body 100 and is spaced apart from the furnace body 100, so that the heat emitted by the heating assembly 200 does not completely enter the furnace body 100, and the radiation distance is lengthened, thereby weakening the infrared radiation effect on the products, and avoiding damage to the products due to excessive heating.

[0047] The movement of the heating assembly 200 in the embodiment is realized by the first driving member 300. Specifically, the output end of the first driving member 300 is connected to the heating assembly 200 and is used to drive the heating assembly 200 to move in the first direction X, so that the heating assembly 200 moves between the closed position and the open position, so that the heating assembly 200 is located in the closed position or the open position. By providing the first driving member 300, the automation of the movement of the heating assembly 200 can be improved, and the efficiency of the movement of the heating assembly 200 is improved. Exemplarily, the first driving member 300 can be a component capable of outputting driving force such as a pneumatic cylinder or a linear motor, and the present embodiment does not limit this.

[0048] The vertical drying equipment provided in the embodiment has the advantages that the height of the furnace body 100 is greater than the width and length of the furnace body 100, and the products extend along the height direction of the furnace body 100 in the furnace body 100, so that on the basis of ensuring that the products have sufficient heating time in the furnace body 100, the space occupied by the furnace body 100 in the horizontal direction is small; and the heating assembly 200 can move between the closed position and the open position under the driving of the first driving member 300, so that when the heating assembly 200 needs to release heat into the furnace body 100, the heating assembly 200 is controlled to be in the closed position, when the moving speed of the products in the furnace body 100 is very small or equal to 0, the first driving member 300 can drive the heating assembly 200 to move to the open position, so that the heating assembly 200 is located outside the furnace body 100 and is spaced apart from the furnace body 100, so that the heat emitted by the heating assembly 200 does not completely enter the furnace body 100, thereby avoiding damage to the products due to excessive heating, reducing the scrap rate, and improving the reliability of the vertical drying equipment.

[0049] Since the volume of the heating assembly 200 is usually large and the weight of the heating assembly 200 is large, if the heating assembly 200 is only supported by the first driving member 300 after moving out of the furnace body 100, the structural strength requirement of the first driving member 300 is high, and the driving effect of the first driving member 300 is affected. In an embodiment, as shown in Figure 1 The vertical drying apparatus further includes a guide mechanism 400. The guide mechanism 400 is connected to the furnace body 100 and the heating assembly 200. One function of the guide mechanism 400 is to support the heating assembly 200, so that the heating assembly 200 in the open position is not completely supported on the first driving member 300, but can be mostly supported on the guide mechanism 400, reducing the structural strength requirement of the first driving member 300 and avoiding the influence on the driving effect of the first driving member 300. Another function of the guide mechanism 400 is to guide the movement of the heating assembly 200 in the first direction X, so as to ensure that the heating assembly 200 moves in the first direction X and avoids tilting and deviating from the first direction X when moving.

[0050] In an embodiment, as shown in Figure 2 The guide mechanism 400 includes a guide rod 410 extending in the first direction X and a guide block 420 slidingly fitted with the guide rod 410 in the first direction X. The guide rod 410 is connected to the furnace body 100, and the guide block 420 is connected to the heating assembly 200. In this way, the guide rod 410 guides the movement of the guide block 420, so that the guide block 420 does not deviate from the first direction X, and the heating assembly 200 does not deviate from the first direction X when moving. In addition, the structure of the guide mechanism 400 is simple, so that the cost of the vertical drying apparatus can be low. Optionally, the guide block 420 is arranged on the surface of the heating assembly 200 away from the furnace body 100, so as not to affect the heating surface of the heating assembly 200.

[0051] In this embodiment, the guide block 420 is provided with a sliding hole and a groove communicating with the sliding hole, the guide rod 410 is arranged in the sliding hole, and the guide rod 410 can enter or move out of the sliding hole in the radial direction through the groove, so as to facilitate the installation and disassembly of the heating assembly 200 and the furnace body 100, and facilitate operation.

[0052] Since the heating assembly 200 is heavy, the guide rod 410 is usually connected to the furnace body 100 vertically along the first direction X. In order to improve the firmness of the guide rod 410, in the embodiment, the guide rod 410 is fixed on the guide rod fixing member 430, the guide rod fixing member 430 is connected to the furnace body 100, and the connection area of the guide rod fixing member 430 and the furnace body 100 can be large, thereby improving the connection strength of the guide rod fixing member 430 and the furnace body 100, and the connection strength of the guide rod 410 and the furnace body 100, so as to avoid the inclination of the guide rod 410 relative to the furnace body 100. In some optional embodiments, the guide rod fixing member 430 and the furnace body 100 can be connected in multiple points, so as to further improve the connection strength and reliability.

[0053] In order to further improve the supporting effect on the heating assembly 200, in the embodiment, as shown in Figure 1 The guide mechanism 400 is provided with multiple groups, and each group of the guide mechanism 400 includes one guide block 420. The multiple guide blocks 420 are arranged at intervals along the circumference of the heating assembly 200, thereby achieving the multi-point support on the heating assembly 200, improving the uniformity of the support on the heating assembly 200, reducing the possibility of the heating assembly 200 in the open position to shake, improving the stability of the heating assembly 200, and further improving the stability of the vertical drying equipment. In the embodiment, the heating assembly 200 is in the shape of a cuboid, and the guide block 420 is arranged at each corner of the heating assembly 200. When the length of the heating assembly 200 is long, the middle part of the heating assembly 200 in the length direction can also be provided with the guide block 420, which is not limited in the embodiment.

[0054] It should be noted that the guide block 420 is located outside the heating assembly 200 in the direction perpendicular to the first direction X, which is convenient for the sliding connection with the guide rod 410, and on the other hand, the guide rod 410 does not need to pass through the heating assembly 200, thereby reducing the structural complexity of the vertical drying equipment.

[0055] In order to improve the overall structural strength of the heating assembly 200, in an implementable manner, a support rod 510 is connected between two adjacent guide blocks 420 in the circumference of the heating assembly 200. By arranging the support rod 510, the distance between the guide blocks 420 can be determined, the stress generated by the deformation of the heating assembly 200 can be borne by the support rod 510, and the guide rod 410 can also assist in supporting the heating assembly 200, thereby further improving the stability and position uniqueness of the heating assembly 200 in the open position, so that the heating assembly 200 can be smoothly moved to the closed position.

[0056] In some optional embodiments, as Figure 3As shown, the heating assembly 200 comprises a frame 210 and a heater 220 mounted on the frame 210, and the heater 220 can be one or more, which is not limited in the embodiment. The guide block 420 is mounted on the frame 210.

[0057] The first driving member 300 in the embodiment is arranged on the furnace body 100. Since the length of the heating assembly 200 will not be the same as the length or width of the furnace body 100, but will be smaller than the length or width of the furnace body 100, if the output end of the first driving member 300 is directly connected with the heating assembly 200, the driving of the heating assembly 200 along the first direction X cannot be realized. In an embodiment, please continue to refer to Figure 3 , the vertical drying equipment further comprises a connecting member 520, and the first driving member 300 is connected with the heating assembly 200 through the connecting member 520, so as to realize the driving of the heating assembly 200 in the first direction X.

[0058] In some optional embodiments, in order to improve the stability of the driving, the heating assembly 200 is connected with the connecting member 520 at both ends in the second direction Y, so that the heating assembly 200 can be driven by multiple driving members, thereby improving the driving effect and driving efficiency. As Figure 3 shown, the connecting member 520 extends along the second direction Y, so as to be able to extend to both sides of the furnace body 100 in the second direction Y, and then the first driving member 300 can be connected with the connecting member 520 after being fixed on both sides of the furnace body 100. Exemplarily, the connecting member 520 can be a U-shaped steel plate, so as to have higher structural strength.

[0059] In an embodiment, the first driving member 300 and the connecting member 520 are provided in plurality one by one, and the output end of each first driving member 300 is connected with the connecting member 520 corresponding thereto, and the multiple first driving members 300 act synchronously, so as to realize the driving of the heating assembly 200. For example, in the embodiment, the first driving member 300 and the connecting member 520 are provided in two respectively, and the two connecting members 520 are connected with both ends of the heating assembly 200 in the second direction Y. By providing multiple first driving members 300, the performance requirement of each first driving member 300 can be reduced.

[0060] In other embodiments, each end of the heating assembly 200 can be connected with multiple connecting members 520, and the multiple connecting members 520 connected with the same end of the heating assembly 200 are connected with the same first driving member 300, so that the utilization rate of the first driving member 300 can be improved.

[0061] In order to ensure the drying effect on the products, in the embodiment, the two side walls of the furnace body 100 in the first direction X are each provided with a heating assembly 200, and each side wall is provided with a plurality of heating assemblies 200, and the plurality of heating assemblies 200 located in the same side wall are arranged in the height direction (i.e. the third direction Z) of the furnace body 100, so that the products can be continuously heated during movement, thereby improving the drying efficiency. Each heating assembly 200 corresponds to one or more first driving members 300, and each heating assembly 200 corresponds to one or more guide mechanisms 400, which are not described in detail in the embodiment.

[0062] In the prior art, in order to facilitate the output of the products and the maintenance of the furnace body 100, the top of the furnace body 100 has an opening 110 (i.e. the outlet of the furnace body 100), which has a large area and can facilitate the repair and replacement of the components in the furnace body 100. In the embodiment, the top of the furnace body 100 is connected with a furnace door 610, which closes the opening 110 of the furnace body 100 when maintenance is not required, so as to avoid heat loss.

[0063] In some optional embodiments, the opening and closing of the furnace door 610 is realized by a furnace door opening and closing mechanism 700. Specifically, as shown in Figure 1 The vertical drying equipment further includes a furnace door opening and closing mechanism 700. The furnace door opening and closing mechanism 700 is used to drive the movement of the furnace door 610, so as to cover or open the opening 110. The provision of the furnace door opening and closing mechanism 700 realizes the automation of the driving of the furnace door 610, thereby improving the automation degree of the vertical drying equipment. For example, the furnace door 610 can move in the length direction or the width direction of the furnace body 100, so as to cover and open the opening 110. In the embodiment, as shown in Figure 2 The furnace door 610 moves in the first direction X.

[0064] The number of the furnace door 610 can be determined according to the size or shape of the opening 110. For example, one furnace door 610 can be provided, and the one furnace door 610 is driven by one furnace door opening and closing mechanism 700, so as to cover or open the opening 110. Of course, it can be understood that a plurality of furnace doors 610 can also be provided, and the plurality of furnace doors 610 are arranged in the circumferential direction of the opening 110, and the plurality of furnace doors 610 cooperate with each other to realize the opening or covering of the opening 110, and each furnace door 610 corresponds to one furnace door opening and closing mechanism 700, so as to realize the individual driving of each furnace door 610.

[0065] For example, as shown in Figure 1 The furnace door 610 in the embodiment is provided with two furnace doors 610, and the two furnace doors 610 are oppositely arranged, specifically, the two furnace doors 610 are oppositely arranged in the first direction X. And, as shown in Figure 2As shown, the furnace door opening and closing mechanism 700 includes two opening and closing assemblies 710 connected with the two furnace doors 610 one by one. Each opening and closing assembly 710 is arranged on the furnace body 100, and each opening and closing assembly 710 is used to drive the furnace door 610 connected therewith to move, so that the two furnace doors 610 are close to or away from each other, thereby realizing that the two furnace doors 610 cover the opening 110 together or open the opening 110 together.

[0066] The embodiment provides an opening and closing assembly 710, as shown in the figure. Figure 4 and Figure 5 As shown, the opening and closing assembly 710 includes a second driving member 711, a screw lifting machine 712, a lifting screw 713, and a shaft coupling 714. The furnace body 100 is connected with a fixed plate 630 extending along the second direction Y, the second driving member 711 is fixedly installed on the fixed plate 630, and the output shaft of the second driving member 711 extends along the second direction Y. The lifting screw 713 extends along the first direction X, and one end of the lifting screw 713 is rotationally connected to the furnace door 610. The shaft coupling 714 is connected between the second driving member 711 and the screw lifting machine 712, and is used to transmit power. The screw lifting machine 712 is sleeved on the lifting screw 713, and the screw lifting machine 712 is used to convert the rotary motion output by the second driving member 711 into the motion of the lifting screw 713 along the first direction X. Exemplarily, the screw lifting machine 712 can be provided with a plurality of gears and a block body screw-connected with the lifting screw 713 inside, and the rotary driving force is converted into a linear driving force through the meshing of the gears and the screw connection of the block body and the lifting screw 713, thereby realizing the driving of the furnace door 610 in the first direction X. Exemplarily, the second driving member 711 in the embodiment can be a speed reducer.

[0067] During the movement of the furnace door 610 relative to the furnace body 100, if the contact area of the furnace door 610 with the furnace body 100 is too large, the resistance of the furnace door 610 to move will be increased, thereby increasing the requirement for the output power of the opening and closing assembly 710. As shown in the figure, Figure 4 or Figure 8 As shown, the two sides of the furnace door 610 are provided with rolling members 620, specifically, the two sides of the furnace door 610 in the second direction Y are provided with rolling members 620, and the rolling members 620 are in rolling contact with the furnace body 100. In this way, the sliding friction between the furnace door 610 and the furnace body 100 is adjusted to rolling friction, so as to reduce the resistance between the furnace door 610 and the furnace body 100.

[0068] In some alternative embodiments, the furnace door 610 is provided with a plurality of rolling elements 620 on each side in the second direction Y to avoid the situation that the part of the furnace door 610 without the rolling elements 620 directly contacts the furnace body 100. The rolling elements 620 include, but are not limited to, bolt-type roller needle bearings. It should be noted that the rolling elements 620 are rotatably sleeved on a rotating shaft (not shown in the figure), one end of the rotating shaft is connected to the furnace door 610, and a locking nut 640 is further arranged between the furnace door 610 and the rolling elements 620, the locking nut 640 is screwed on the rotating shaft and is used to adjust the difficulty of rolling of the rolling elements 620 relative to the furnace body 100.

[0069] Optionally, as shown in Figure 1 , the top surface of the furnace body 100 is provided with a rolling table 120, and the rolling elements 620 are in rolling contact with the rolling table 120, so that the installation position of the rolling elements 620 on the furnace door 610 does not need to be set too low.

[0070] Since the temperature in the furnace body 100 of the vertical drying equipment during normal operation is as high as several hundred degrees Celsius, the furnace door 610 is inevitably affected by the temperature in the furnace. Although the side of the furnace door 610 facing the furnace is made of heat insulation material, the temperature of the whole furnace door 610 is still higher than the normal temperature after the heating state is stable. The assembly of the furnace door 610 and the furnace body 100 is carried out at normal temperature, and the temperature in the furnace body 100 of the vertical drying equipment in use and the temperature of the furnace door 610 are higher than the normal temperature, so the thermal expansion of the furnace door 610 needs to be considered. Among them, Figure 6 , the double-headed arrow represents the thermal expansion of the furnace door 610 in the first direction X. The thermal expansion in the first direction X can be solved by the first expansion matching mechanism 800.

[0071] In one implementation manner, as shown in Figure 6 , the vertical drying equipment further comprises a first expansion matching mechanism 800. Among them, the first expansion matching mechanism 800 comprises a first bearing 810 and a first guide shaft 820. The first guide shaft 820 extends along the width direction (i.e. the first direction X) of the furnace door 610, and one end of the first guide shaft 820 is connected to the furnace door 610, and the first bearing 810 is connected to the furnace body 100 and is slidably sleeved on the first guide shaft 820. When the furnace door 610 expands in the first direction X, the first bearing 810 slides on the first guide shaft 820 to prevent the furnace door 610 from being damaged due to excessive stress.

[0072] For example, for a furnace door 610, one or more sets of first expansion fitting mechanisms 800 may be provided, and this embodiment does not limit this. In this embodiment, each furnace door 610 corresponds to two sets of first expansion fitting mechanisms 800, and the two sets of first expansion fitting mechanisms 800 are arranged at both ends of the furnace door 610 along the length direction of the furnace door 610, and the lifting screw 713 is connected to the middle part of the furnace door 610 along the length direction.

[0073] like Figure 7 As shown, the furnace door 610 will also expand and deform in the length direction (i.e., the second direction Y). The expansion movement of the furnace door 610 in the second direction Y is most likely to cause jamming. In this embodiment, in order to overcome the expansion movement of the furnace door 610 in the second direction Y, a second expansion and mating mechanism 900 is added.

[0074] Specifically, such as Figure 6 and Figure 7 As shown, the vertical drying equipment also includes a second expansion and fitting mechanism 900. The second expansion and fitting mechanism 900 includes a second bearing 910 and a second guide shaft 920. The second guide shaft 920 extends along the length direction (i.e., the second direction Y) of the furnace door 610 and is connected to the furnace door 610. The second bearing 910 is slidably fitted onto the second guide shaft 920, allowing it to slide on the second guide shaft 920. Furthermore, the second bearing 910 is connected to the first guide shaft 820, specifically, the end of the second guide shaft 820 closest to the furnace door 610. When the furnace door 610 expands and moves in the second direction Y, the furnace door 610 drives the second guide shaft 920 to slide relative to the second bearing 910. This provides space for the expansion of the furnace door 610 without affecting the position of the first guide shaft 820 in the second direction Y, preventing large stress from being generated between the first guide shaft 820 and the furnace door 610, thus preventing damage to the first guide shaft 820 or the furnace door 610. This results in high reliability.

[0075] For example, such as Figure 7 As shown, one end of the first guide shaft 820 is connected to a mounting base 830, and the mounting base 830 is fixedly connected to the second bearing 910 to realize the connection between the first guide shaft 820 and the second bearing 910.

[0076] Alternatively, in order to prevent the furnace door 610 from falling off due to excessive movement along the second direction Y, fixed limiting plates 930 are installed at both ends of the second guide shaft 920.
