[0035] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0037] The embodiment of the utility model provides a drying device, which is mainly used for drying flammable, explosive and volatile parts in coating equipment. For example, when the positive electrode of the battery is dried, it will volatilize flammable and explosive gases. If the gas enters the drying device with poor sealing effect, it is very easy to cause explosion and cause production accidents.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, a drying device provided by an embodiment of the utility model includes a main shell 100 and an infrared emitting plate 200; a accommodating cavity 110 is arranged in the main shell 100, and the accommodating cavity 110 is extended in a horizontal direction, and a sealing plate 120 is arranged on the side of the main shell 100 close to the part to be dried, and the material of the sealing plate 120 is set to be a transparent material; the infrared emitting plate 200 is arranged in the accommodating cavity 110 along the extension direction of the accommodating cavity 110, and the infrared emitting plate 200 is arranged toward the part to be dried.

[0039] That is, the drying device provided by the embodiment of the utility model, by simultaneously setting the infrared emitting plate 200 in the sealed accommodating cavity 110 and setting a transparent sealing plate 120 in the direction of the infrared emitting plate 200 toward the part to be dried, ensures that the infrared emitting plate 200 can emit infrared light to the part to be dried to heat and dry it, and at the same time ensures the sealing of the drying device to prevent flammable and explosive volatile gases from entering the drying device, thereby solving the technical problems of poor sealing effect, excessive energy density and overall temperature of the coating equipment in the prior art, and is suitable for drying flammable, explosive and volatile parts.

[0040] Specifically, the main housing 100 is an enclosed box body that is long and narrow as a whole, and the cross-sectional shape in the length direction is approximately a rectangular frame. The accommodating cavity 110 is arranged along the length direction of the main housing 100, and its cross-sectional shape is rectangular. In order to ensure the good heat dissipation performance of the main housing 100, the main housing 100 can be made of metal materials such as aluminum alloy. The infrared emitting board 200 is specifically arranged as an infrared radiation board made of high-temperature synthetic ceramics, which has the advantages of uniform radiation, controllable radiation intensity, and rapid heating. The infrared emitting board 200 is in the shape of a rectangular plate as a whole, arranged along the length direction of the accommodating cavity 110, and the radiation surface of the infrared emitting board 200 is arranged vertically downward. The sealing plate 120 is arranged to be made of transparent glass and is fixed to the bottom of the main housing 100 by clamping, bolting or bonding. Thus, the infrared light emitted by the infrared emitting board 200 can pass through the sealing plate 120 to irradiate the parts to be dried below the drying device.

[0041] Furthermore, the drying device also includes a shell side panel 400 and a connecting wire. The two shell side panels 400 are arranged at both ends of the main shell 100 and are connected to the main shell 100 to enclose and form a accommodating cavity 110. A mounting hole 410 is provided on the shell side panel 400. One end of the connecting wire passes through the mounting hole 410 and is connected to the infrared emitting board 200, and the other end of the connecting wire is used to connect to the power supply.

[0042] Specifically, the two housing side panels 400 are arranged at both ends of the main housing 100 in the vertical direction, and can be connected to the main housing 100 by bolt connection or bonding. Thus, a closed receiving cavity 110 can be formed by cooperating with the main housing 100. The mounting hole 410 is arranged in a circular shape and is located at the center of the housing side panel 400 to facilitate the connection wire to enter the receiving cavity 110 and connect with the infrared emitting board 200. Thus, the connection between the infrared emitting board 200 and the external power supply can be completed while ensuring the airtightness of the receiving cavity 110.

[0043] Preferably, the drying device further includes a sealing gasket 420 , and the sealing gasket 420 is disposed in the mounting hole 410 .

[0044] Specifically, the sealing gasket 420 is configured as a sealing ring made of rubber, which is inserted into the mounting hole 410. When the connecting wire passes through the mounting hole 410, it needs to pass through the sealing gasket 420. The shape and size of the ring hole of the sealing gasket 420 are adapted to the cross-sectional shape and size of the connecting guide, and the sealing gasket 420 and the connecting wire have an interference fit. In this way, the gap between the connecting wire and the mounting hole 410 can be sealed by the sealing gasket 420 to prevent the volatilized inflammable and explosive gas from entering the accommodating cavity 110 and causing an explosion accident.

[0045] Furthermore, the main shell 100 includes a first shell 130, on which a first mounting groove 131 is provided. The two first shells 130 are arranged opposite to each other in a horizontal direction, and both sides of the infrared emitting board 200 are embedded in the first mounting groove 131 to separate the accommodating cavity 110 into a first cavity 111 and a second cavity 112.

[0046] Specifically, the first shell 130 is in an elongated shape as a whole and is made of aluminum alloy, and is arranged along the extension direction of the accommodating cavity 110. The two first shells 130 are arranged opposite to each other, and the first mounting groove 131 is arranged on the opposite sides of the two first shells 130. In the present embodiment, the first mounting groove 131 is arranged as a rectangular groove to adapt to the shape of the infrared emitting board 200, and the openings of the two first mounting grooves 131 are opposite, one side of the infrared emitting board 200 is arranged in one of the first mounting grooves 131, and the other side of the infrared emitting board 200 is arranged in the other first mounting groove 131. In this way, the infrared emitting board 200 can be fixed in the two mounting grooves in the horizontal direction. At the same time, in order to improve the installation stability of the infrared emitting board 200, adhesive or bolt holes can be set at both ends of the infrared emitting board 200 to facilitate the bonding or bolting of the infrared emitting board 200 in the first mounting groove 131. The first mounting groove 131 is disposed in the middle of one side of the first housing 130, so that after the infrared emitting board 200 is fixed in the first mounting groove 131 in the horizontal direction, it is located in the middle of the accommodating cavity 110. Thus, the accommodating cavity 110 is divided into two parts, the part below the infrared emitting board 200 is the first cavity 111, and the part above the infrared emitting board 200 is the second cavity 112.

[0047] Preferably, a cooling cavity 132 is provided in the first shell 130, and a cooling hole is provided on the side of the first shell 130 close to the infrared emitting plate 200, and the cooling hole is configured to connect the cooling cavity 132 and the accommodating cavity 110, and an air inlet hole 133 is provided at one end of the cooling cavity 132, and the air inlet hole 133 is used to connect to a cold air source.

[0048] Specifically, the cooling chamber 132 is arranged through the first shell 130 along the length direction of the first shell 130, and the cooling hole is arranged on the side wall of the first shell 130 close to the infrared emitting board 200. A plurality of cooling holes are evenly arranged along the length direction of the first cavity 111, and the cooling holes can be provided with long slot holes, round holes or waist-shaped holes. In this way, the cooling chamber 132 and the accommodating cavity 110 can be connected through the cooling holes. The two ends of the cooling chamber 132 are respectively abutted against the shell side plates 400, and the two ends of the cooling chamber 132 are closed by the shell side plates 400. An air inlet 133 is provided on one of the shell side plates 400, and is connected to an external cold air source through a pipeline, so that the cold air from the external cold air source can be introduced into the cooling chamber 132, and enters the accommodating cavity 110 through the cooling hole, thereby cooling the infrared emitting board 200, reducing the temperature of the infrared emitting board 200, and reducing the risk of overheating and damage to the infrared emitting board 200.

[0049] Preferably, a first cooling hole 134 and a second cooling hole 135 are provided on the first shell 130, one end of the first cooling hole 134 is connected to the first cavity 111, the other end of the first cooling hole 134 is connected to the cooling cavity 132, one end of the second cooling hole 135 is connected to the second cavity 112, and the other end of the second cooling hole 135 is connected to the cooling cavity 132.

[0050] Specifically, the first cooling hole 134 is arranged below the first mounting groove 131, so that one end of the first cooling hole 134 is connected to the first cavity 111, and the other end of the first cooling hole 134 is connected to the cooling cavity 132, and the second cooling hole 135 is arranged above the first mounting groove 131, so that one end of the second cooling hole 135 is connected to the second cavity 112, and the other end of the second cooling hole 135 is connected to the cooling cavity 132. Therefore, by arranging cooling holes on both sides of the first cavity 111 and the second cavity 112, cold air can be introduced into the first cavity 111 and the second cavity 112 at the same time, and then the upper and lower sides of the infrared emitting plate 200 are cooled at the same time, thereby improving the cooling efficiency of the infrared heating plate and improving the cooling uniformity of the infrared emitting plate 200.

[0051] Furthermore, the drying device also includes an infrared emitting sub-board 300 . A second mounting groove 136 is also provided on the first shell 130 . The second mounting groove 136 is arranged parallel to the first mounting groove 131 . Both sides of the infrared emitting sub-board 300 are embedded in the two second mounting grooves 136 .

[0052] Specifically, the second mounting groove 136 is arranged above the first mounting groove 131 and on the same side of the first mounting groove 131. The infrared emitting sub-board 300 is arranged as an infrared radiation board identical to the infrared emitting board 200. One side of the infrared emitting sub-board 300 is arranged in one of the second mounting grooves 136, and the other side of the infrared emitting sub-board 300 is arranged in another second mounting groove 136, thereby the infrared emitting sub-board 300 can be fixed in the two second mounting grooves 136 in the horizontal direction. At the same time, in order to improve the installation stability of the infrared emitting sub-board 300, adhesive or bolt holes can also be arranged at both ends of the infrared emitting sub-board 300 to facilitate the bonding or bolting of the infrared emitting sub-board 300 in the second mounting groove 136. When the drying device is long as a whole, the infrared emitting board 200 needs to be spliced. The infrared emitting sub-board 300 is configured as a short infrared radiation board, which is used to be disposed at the joint of the infrared emitting board 200 to supplement the infrared radiation at the joint to avoid insufficient infrared light radiation temperature at the joint of the infrared emitting board 200.

[0053] Furthermore, the drying device also includes a hot air channel 500, and the two hot air channels 500 are arranged on both sides of the main shell 100 along the extension direction of the main shell 100 and are connected to the main shell 100. The hot air channel 500 is connected to the hot air source, and a nozzle 510 is arranged at the bottom of the hot air channel 500, and the nozzle 510 is arranged toward the parts to be dried.

[0054] Specifically, the hot air channel 500 is fixed to both sides of the main housing 100 by bolts or welding, and is connected to the outer wall of the first housing 130. The top of the hot air channel 500 is connected to an external hot air source, and the air nozzles 510 of the hot air channel 500 are arranged at the bottom of the hot air channel 500, and the two air nozzles 510 are arranged downward toward the parts to be dried. In this way, hot air can be blown to the parts to be dried through the hot air channel 500. Since the hot air flow continues to flow at the top of the parts to be dried, the heat exchange between the parts to be dried and the hot air flow at the top will be accelerated, so that the temperature of the parts to be dried rises evenly, ensuring the uniformity of drying and heating of the parts to be dried, and further improving the drying efficiency of the drying device.

[0055] Preferably, the main shell 100 further includes a second shell 140 , which is disposed on the top of the first shell 130 and connected to the first shell 130 , and the sealing plate 120 is disposed on the bottom of the shell and connected to the first shell 130 .
