A plurality of spraying groups 11 are circumferentially fixed on the feeding turntable 13 around its axis. The input ends of the spraying groups 11 are respectively used to connect to the supply devices of different materials.

By setting a plurality of spraying groups 11 on the feeding turntable 13, the switching during the drying of different materials is realized, and each spraying group 11 dedicated to different materials is formed, ensuring the purity of the material and the convenience of material switching.

[0046] Specifically, the rotating mechanism is used to drive the feeding turntable 13 to rotate. The rotating mechanism is an existing device, that is, any mechanism or device that can drive the feeding turntable 13 to rotate can be used.

[0047] Specifically, each spraying group 11 on the feeding turntable 13 is communicated with the extraction pump in the corresponding material cylinder through a feeding pipe; in order to ensure that when the rotating mechanism drives the feeding turntable 13 to rotate, the feeding pipes will not be twisted together, the following methods can be used, including but not limited to: for example, the maximum rotation angle of the output shaft of the rotating mechanism is set to 180°, and it can rotate left and right.

[0048] Specifically, a single material spraying group 11 corresponds to a material grid 50, and each material spraying outlet 12 on the material spraying group 11 corresponds to the material placing groove 51 of the material grid 50 one by one.

[0049] Specifically, when it is necessary to switch to different materials for drying, by rotating the feeding turntable 13, the corresponding material spraying group 11 can be switched. At this time, the material grids 50 on the conveyor belt 31 can be cleaned and then used, or the material grids 50 on the conveyor belt 31 can be replaced, so as to reduce the influence of the mixture of the materials dried last time on the current material drying.

[0050] Specifically, the thickness of the material dropped by the material spraying outlet 12 can be determined according to the actual drying effect of the infrared radiation source 25 and the bottom heating module 24, as well as the running speed of the conveyor belt 31 and other conditions.

[0051] Regarding the setting of the drying device 20:

The hot air conveying mechanism 22 has an air supply port, and the hot air conveying mechanism 22 is used to supply hot air; the condensation recovery mechanism includes a condensation pipe 23 and a recovery device. The inlet end of the condensation pipe 23 is a return air port, and the outlet end of the condensation pipe 23 is connected to the recovery device. The ventilation system selects the hot air conveying mechanism 22 and the condensation recovery mechanism. By introducing hot air, on the one hand, it can ensure the temperature in the drying box 21, thus ensuring the stable drying of the material and taking away the evaporated water vapor stably and in time; the condensation recovery mechanism can cool and recover the materials and other substances contained in the discharged gas, improve the material yield, and reduce the loss of materials.

[0055] Specifically, the hot air conveying mechanism 22 can be any existing device that can provide hot air (such as hot air or other gases that do not react with the material), and the hot air conveying mechanism 22 can adjust the hot air supply amount and the hot air speed to suit the hot air supply of different materials.

[0056] Specifically, the condensation recovery mechanism can be any existing device that can recover some recyclable substances in the discharged gas through condensation. For example, a condenser has a condensation channel and a condensation medium circulation channel. The air outlet 212 of the drying oven 21 is connected and communicated with one end of the condensation channel. The liquid flowing down through condensation in the condensation channel is collected by a collector, and the remaining gas in the condensation channel can be discharged after being processed by a gas treatment device.

[0060] In an alternative solution of this embodiment, preferably, the infrared radiation source 25 is an infrared lamp. The infrared radiation source 25 uses an infrared lamp, and its components are common and easy to obtain, which is convenient for installation and use.

[0061] Among them, regarding the conveying mechanism 30:

[0062] Specifically, the conveying mechanism 30 is an existing device, including a conveyor belt 31 and a driving mechanism for driving the conveyor belt 31 to rotate.

[0063] Specifically, the conveying surface mentioned in this embodiment is the conveying surface of the conveyor belt 31 that conveys from the conveying starting end to the conveying ending end.

The tensioner 32 can adjust the tension degree of the conveyor belt 31, thereby providing a stable conveying surface for the dried materials, enabling the materials to be stably conveyed during the drying process, and improving the drying effect.

[0065] In the optional scheme of this embodiment, it is more preferred that an anti-sticking layer is provided on the inner wall of each material storage groove 51. The anti-sticking layer provided in the material storage groove 51 can reduce the adhesion effect of the material and ensure that the dried material can be stably separated from the material storage groove 51.

[0066] Among them, in order to cool down the dried material in time, the following settings can also be made:

[0067] Among the optional solutions of this embodiment, it is more preferred that Figure 1 As shown, along the conveying direction of the conveying surface, a cooling module 33 is also provided on one side of the drying box 21 close to the conveying end of the conveyor belt 31. The cooling module 33 is located below the corresponding conveying surface.

The cooling module 33 is provided at the rear side of the drying box 21, which can reduce the temperature of the dried material in time and improve the post-processing efficiency of the material after drying.

[0068] Specifically, the cooling module 33 is any existing device capable of providing low temperature, and cools down the dry material with a certain temperature in the material grid 50 on the corresponding conveyor belt 31 by providing a low temperature environment.

[0069] The materials in each material storage slot 51 of the material grid 50 can be smoothly dropped out in the following ways, including but not limited to:

[0070] First, among the optional solutions of this embodiment, it is more preferred that Figure 1 As shown, a plurality of shelf holes are provided on the conveying surface of the conveyor belt 31, and a material grid 50 is fixed in each shelf hole; the upper end of the material grid 50 is not higher than the conveying surface, and each material shelf groove 51 of the material grid 50 extends to the inner side of the conveyor belt 31; the conveying end of the conveyor belt 31 is sleeved on a rotating shaft 40, and the outer wall of the rotating shaft 40 can contact and extrude with the lower end of each material shelf groove 51 of the material grid 50; the outer wall of the rotating shaft 40 forms an extrusion portion. The rotating shaft 40 that rotates with the conveyor belt 31 and the material grid 50 that extends to the inner side of the conveyor belt 31 are matched. When the material grid 50 is driven to the rotating shaft 40 by the conveyor belt 31, the outer wall of the rotating shaft 40 will contact and extrude the material grid 50. Based on the elastic deformation of the material grid 50, the dried material in the material shelf groove 51 is separated from the inner wall thereof during the extrusion process, so that the material falls off smoothly.

[0071] Specifically, at this time, the cooperation mode between the rotating shaft 40 and the transmission belt is as follows: Figure 3 As shown, at this time, the width of the conveyor belt 31 is smaller than the length of the rotating shaft 40.

[0072] Second, among the optional solutions of this embodiment, it is more preferred that Figure 1As shown, an air hammer vibrator 70 is provided inside the conveyor belt 31. The air hammers of the air hammer vibrator 70 can pound and squeeze each material placement groove 51 of the material grid 50 passing through here; the air hammers of the air hammer vibrator 70 form an extrusion part. Using the air hammers of the air hammer vibrator 70 to extrude and pound the passing material grid 50, combining the effects of extrusion and vibration, effectively acts on the dry materials in the material placement groove 51, making it more smoothly fall off.

[0073] Specifically, at this time, the installation position of the air hammer vibrator 70 can be any position after the material drying is completed, such as Figure 1 the two positions shown in. For example, this position is at the conveying end of the conveyor belt 31. At this time, the conveying end of the conveyor belt 31 is sleeved on two symmetrical rotating shafts 40. There is a gap between the two symmetrical rotating shafts 40, and the air hammer vibrator 70 is installed in this gap, that is, the position of the air hammer vibrator 70 indicated by the dotted line in Figure 1 ; this position can also be on the return part of the conveyor belt, such as the position of the air hammer vibrator 70 indicated by the solid line in Figure 1 .

[0074] Specifically, to ensure good material falling-off effect, the size of the air hammers of the air hammer vibrator 70 for extrusion covers the size of the material grid 50, so as to ensure the extrusion of each position of the material grid 50.

[0075] Regarding the collector 60:

[0076] Specifically, the collector 60 is any existing collection container, which is used to collect the dried materials that fall off from each material placement groove 51.

[0077] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope.
