Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery pot production, in particular to a drying device special for lithium battery pot production. BACKGROUND

[0002] The lithium battery pot is a key appliance for supporting the positive material or negative material in the lithium battery production process, and is used to protect the lithium battery material from oxidation, pollution and damage during high-temperature sintering.

[0003] The lithium battery pot production and processing process includes design drawing, material preparation, blank processing, heat treatment, surface treatment, quality inspection and other links. After the blank is machined, it may contain a certain amount of moisture, especially after the cutting fluid cooling or cleaning process, the moisture will remain in the blank. If the drying treatment is not performed, the moisture may cause the blank to crack, deform and other defects during the subsequent heat treatment process, affecting the quality and performance of the mold. Therefore, the moisture in the blank needs to be removed by a special drying device to ensure that the blank reaches the appropriate dryness level so that the subsequent heat treatment and other processes can proceed smoothly.

[0004] The existing drying device mainly has the following types: Box-type drying oven: composed of a heat preservation box, heating elements, a circulating fan, a temperature control system, etc. The heating elements heat the air in the box, and the circulating fan circulates the hot air in the box to achieve uniform heating.

[0005] Tunnel-type drying kiln: with a tunnel-type kiln body, the pot is slowly moved in the kiln by a conveying device, and the kiln is provided with multiple heating zones. Different temperatures are set for different drying stages to ensure uniform heating of the pot.

[0006] Net belt type drying machine: composed of a net belt conveying system, a heating system, a ventilation system, etc. The lithium battery pot is placed on the net belt, which moves at a uniform speed in the heating area. Hot air fully contacts the pot through the net belt to achieve drying.

[0007] The above drying methods can uniformly dry the sagger mold. In actual drying process, since the sagger mold is usually made of high-temperature-resistant materials, the thermal conductivity of these materials is low, which causes the heat to be slowly transferred to the inner wall of the mold, which makes the heating process of the inner wall slow, and the moisture on the surface of the mold is easily evaporated first to form a relatively dry shell. Since the path of the moisture in the inner wall to the outside is long and is hindered by the shell, the moisture in the inner wall is difficult to evaporate quickly, therefore, the moisture in the inner wall is not easy to evaporate. Although the whole mold is finally dried, in fact, the four corners and edges of the mold blank are dried faster than the inner wall, which is prone to the problems of local over-drying or drying stress concentration. In the subsequent heat treatment process, cracks may occur on the outside, which will affect the quality and service life of the mold.

[0008] In view of the above problems, it is urgent to make innovative design on the basis of the original drying device. SUMMARY

[0009] The technical scheme of the present application provides a significantly different solution from the prior art, and specifically aims to provide a special drying device for lithium battery sagger production, to solve the problem that the four corners and edges of the mold blank are dried faster than the inner wall during the drying work of the existing drying device, resulting in drying stress concentration and affecting the final service life of the mold.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0031] Please refer to Figures 1 to 7The application provides a technical scheme: a drying device special for lithium battery pot production, which comprises a drying box 1 and a conveying mechanism 2 installed inside the drying box 1, and further comprises a plurality of hot air guiding mechanisms 3 arranged on the top of the drying box 1 and capable of dynamically circulating air to the inner wall of the pot, a plurality of object plates 4 distributed at equal intervals on the conveying mechanism 2 and capable of transporting the pots to the lower side of the hot air guiding mechanisms 3 one by one.

[0032] A hot air machine 5 is installed outside the drying box 1, and a hot air pipe 6 is installed on one side of the hot air machine 5, so that the hot air machine 5 can transport hot air to the hot air guiding mechanisms 3 and the lower side of the object plates 4 through the hot air pipe 6, and the inner wall and the outer contour of the pot can be dried by hot air at the same time.

[0033] By installing a plurality of arrayed hot air guiding mechanisms 3 in the drying box 1, the inner wall of the pot can be directed to blow air, and the hot air coverage range can be adjusted in real time, so that the hot air can converge to the center along the edge of the inner wall of the pot and then diffuse outward. This dynamic circulating air mode can avoid local overheating and eliminate the drying blind area, significantly improve the uniformity and efficiency of the drying of the inner wall of the pot, and ensure that the edge of the inner wall of the pot is fully and uniformly dried.

[0034] Meanwhile, a plurality of object plates 4 are distributed at equal intervals on the conveying mechanism 2, and the pots are accurately transported one by one to the lower side of the hot air guiding mechanisms 3 through the conveying mechanism 2, so as to realize the precise butt joint of the pot and the hot air guiding mechanism 3 and realize efficient drying treatment.

[0035] In addition, the hot air pipe 6 in the embodiment transports the hot air of the hot air machine 5 to the lower side of the hot air guiding mechanisms 3 and the object plates 4 respectively, so that the hot air is uniformly distributed in the drying box 1 and the inner wall and the outer contour of the pot are synchronously and efficiently dried. In the embodiment, as shown in Figure 4 and Figure 5 Each hot air guiding mechanism 3 comprises a wind collecting disc 301, an internal hollow pipe 302 penetrating through the wind collecting disc 301, and a plurality of shunt pipes 303 inserted at equal angles on the lower surface of the wind collecting disc 301, and the plurality of shunt pipes 303 are connected with the wind collecting disc 301 through corrugated hoses 304.

[0036] A positioning ring 305 is slidably connected outside the hollow pipe 302, a plurality of supporting rods 306 are rotatably connected outside the positioning ring 305, and the other ends of the plurality of supporting rods 306 are rotatably connected with the outside of the shunt pipes 303.

[0037] By sliding the supporting rods 306 along the length direction of the hollow pipe 302, the shunt pipes 303 are driven to expand outward or contract inward with the central axis of the hollow pipe 302 as the center.

[0038] It should be noted that the air collecting disc 301 is installed on the top of the inner wall of the drying box 1 to collect the hot air generated by the hot air fan 5, the hollow pipe 302 is located at the center of the air collecting disc 301, and the distribution pipes 303 are uniformly distributed on the lower surface edge of the air collecting disc 301, and the air outlets thereof are designed to be inclined downward so as to effectively guide the hot air to the side wall and each corner of the inner wall of the lower box. By adjusting the opening and closing angle of the distribution pipes 303, the inclination angle thereof can be adjusted in real time.

[0039] Specifically, the larger the angle, the wider the drying area, and the more uniform the distribution of hot air. Conversely, the smaller the angle, the more concentrated the drying area, and the more concentrated the hot air.

[0040] In addition, the hollow pipe 302 is externally provided with a positioning ring 305 which can slide along the length direction thereof, the outer periphery of the positioning ring 305 is uniformly rotationally connected with a plurality of supporting rods 306, the other end of each supporting rod 306 corresponds to one of the distribution pipes 303, when the positioning ring 305 slides along the hollow pipe 302, the supporting rods 306 move synchronously to drive the distribution pipes 303 to adjust the angle thereof around the central axis of the hollow pipe 302, so as to realize the outward expansion or inward folding of the distribution pipes 303. The distribution pipes 303 are flexibly connected with the air collecting disc 301 through the corrugated hose 304, so as to ensure that the distribution pipes 303 can still maintain stable hot air transmission when the angle is adjusted. When the supporting rods 306 drive the distribution pipes 303 to fold towards the center, the hot air is gathered from the edge of the inner wall of the box to the center to realize the deep drying of the central area of the box. When the supporting rods 306 drive the distribution pipes 303 to expand outward, the hot air is diffused from the center to the edge to complete the temperature compensation of the edge part. Through this dynamic and cyclic reciprocating mode, the hot air drying operation can be continuously carried out, the distribution and control of the hot air are more reasonable, and the local over-drying of the inner wall is avoided.

[0041] In the embodiment, as shown in Figure 5 and Figure 6 , one end of the hollow pipe 302 extends to the outside through the lower surface of the air collecting disc 301, the hollow pipe 302 located outside the air collecting disc 301 is provided with a sliding groove, and the hollow pipe 302 located inside the air collecting disc 301 is provided with a ventilation hole.

[0042] The bottom of the hollow pipe 302 is provided with a conical air outlet cover, the hot air in the air collecting disc 301 enters the hollow pipe 302 through the ventilation hole, and is diffused outward through the conical air outlet cover and the sliding groove.

[0043] It should be noted that the upper end of the hollow tube 302 is located inside the wind collecting disc 301, and the lower end is located outside the wind collecting disc 301. The hot air in the wind collecting disc 301 penetrates into the hollow tube 302 through the air permeable hole. The hollow tube 302 is arranged vertically downward. The conical air outlet cover of the hollow tube 302 diffuses the hot air downward, concentrates the center position of the inner wall of the drying kiln, and makes the moisture in the central area evaporate quickly. At the same time, the hot air is diffused to both sides of the inner wall of the drying kiln through the chute on both sides, so that the hot air distribution of the hollow tube 302 is more uniform.

[0044] In the embodiment, as shown in Figure 6 and Figure 7 , the inner wall of the positioning ring 305 is welded with a sliding block 307 vertically sliding along the chute. The top of the sliding block 307 is welded with one end of a connecting rod 308. The other end of the connecting rod 308 is connected with a hydraulic rod 309.

[0045] It should be noted that in the embodiment, as shown in Figure 4 , the hydraulic rod 309 is arranged outside the drying box 1. The piston rod of the hydraulic rod 309 is connected with the connecting rod 308. The connecting rod 308 is arranged inside the hollow tube 302. The reciprocating movement of the piston rod of the hydraulic rod 309 drives the connecting rod 308 and the sliding block 307 to slide up and down. Since the sliding block 307 is fixed with the positioning ring 305 as a whole, the displacement of the sliding block 307 will synchronously drive the positioning ring 305 to move axially along the hollow tube 302, and finally realize the reciprocating swing of the shunt pipe 303. Specifically, when the piston rod of the hydraulic rod 309 is extended, the positioning ring 305 is pushed to slide downward. The included angle between the supporting rod 306 and the hollow tube 302 gradually decreases, so that the shunt pipe 303 is folded inward around the central axis of the hollow tube 302, causing the air outlets of the shunt pipes 303 to concentrate. The hot air is concentrated on the central area of the inner wall of the drying kiln, and the concentrated drying operation is performed. Conversely, when the piston rod of the hydraulic rod 309 is retracted, the positioning ring 305 slides upward. The included angle between the supporting rod 306 and the hollow tube 302 increases, the shunt pipe 303 is unfolded outward, the air outlets are inclined outward around the central axis of the hollow tube 302, and the hot air is uniformly diffused to the entire inner wall of the drying kiln. Through the hydraulic rod 309, the shunt pipe 303 performs the dynamic cycle drying process of folding from the edge to the center and then unfolding outward, performs dynamic cycle air supply to the inner wall of the drying kiln, and achieves efficient and uniform drying effect.

[0046] In addition, it should be particularly pointed out that in the embodiment, the position of the piston rod of the hydraulic rod 309 can also be accurately controlled according to actual needs, so as to accurately control the unfolding angle of the shunt pipe 303 to remain unchanged, to realize static concentrated air supply to a certain specific area inside the drying kiln, to concentrate drying, and to have higher drying efficiency.

[0047] In the embodiment, as shown in Figure 2 and Figure 3As shown, the conveying mechanism 2 comprises a chain wheel 201 connected with the drying box 1, a rotating shaft 202 installed on the inner wall of the chain wheel 201, and a chain 203 engaged with the outer side of the chain wheel 201. A driven gear 204 is installed on one side of one of the chain wheels 201, and a driving gear 205 is engaged with one side of the driven gear 204.

[0048] In the embodiment, as shown in Figure 3 the driving gear 205 is an incomplete gear, the driving gear 205 and the driven gear 204 are intermittently driven, and the inner wall of the driving gear 205 is provided with a driving motor 206.

[0049] It should be noted that the driving gear 205 is designed as a half-tooth structure, i.e. an incomplete gear with one half having teeth and the other half being toothless. When the driving gear 205 completes one full rotation, the driven gear 204 only rotates half a circle. The driven gear 204 is connected with the chain wheel 201 through a rotating shaft 202, so as to drive the chain wheel 201 to rotate half a circle.

[0050] In addition, the driving distance of the chain 203 driven by the half-rotation of the chain wheel 201 is just enough to make the placing plate 4 be conveyed from the current position to the next hot air guiding mechanism 3, so as to perform the next round of hot air drying operation. When the chain wheel 201 completes half-rotation, the toothless part of the driving gear 205 is in contact with the driven gear 204, and the chain wheel 201 stops rotating immediately, so as to keep the top placing plate 4 in a stationary state, which facilitates the top hot air guiding mechanism 3 to perform concentrated drying on the inner wall of the sagger on the surface of the placing plate 4. Through the intermittent conveying of the conveying mechanism 2, the saggerts on the surface of each placing plate 4 are conveyed to the lower side of the hot air guiding mechanism 3 one by one, which can not only ensure that the saggerts enter the working positions of the hot air guiding mechanisms 3 in an orderly manner, but also realize efficient concentrated drying on the inner wall of the saggerts.

[0051] In addition, it is worth noting that in the embodiment, a speed-reducing motor is selected as the driving motor 206, so as to ensure that the placing plate 4 has sufficient staying gap under the hot air guiding mechanism 3, and at least the flow dividing pipe 303 of the hot air guiding mechanism 3 can complete two full swing periods.

[0052] In the embodiment, as shown in Figure 1 and Figure 2 the inner wall of the chain 203 is fixedly connected with the placing plate 4 through a steel pipe, and the inner wall of the placing plate 4 is provided with a plurality of obliquely installed partition plates 7, and an obliquely upward flow guiding groove is formed between two adjacent partition plates 7.

[0053] One end of the hot air pipe 6 is inserted into the surface of the air collecting disc 301, and the other end of the hot air pipe 6 is provided with a wind diffuser 8, which is located directly below the hot air guiding mechanism 3.

[0054] It should be noted that one end of the hot air pipe 6 is inserted into the surface of the wind collecting disc 301, and the other end is provided with a wind diffuser cover 8, the air outlet of the wind diffuser cover 8 is aligned with the storage plate 4, the storage plate 4 is conveyed to the lower side of the hot air guide mechanism 3 by the chain 203, the inner wall of the storage plate 4 is provided with a plurality of inclined partition plates 7, the partition plates 7 form inclined flow guide groove surfaces to both sides, each flow guide groove surface can generate an independent air flow beam, can be aligned with the outer part of the sagger to direct the air supply, and can radiate hot air to both side edges, cooperate with the hot air guide mechanism 3 to perform drying operation on the inner wall of the sagger, realize simultaneous drying of the inside and outside of the sagger, avoid local over-drying, ensure uniformity of the inside and outside dryness of the sagger, and greatly improve the drying efficiency.
