DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] As Figures 1 to 7 shown, the present application provides a kind of mixed drying device, including drying barrel 1, the middle part of drying barrel 1 is provided with communication assembly 2, drying barrel 1 and communication assembly 2 between being provided with several stirring blades 3 of uniform distribution, one end of stirring blade 3 is fixedly connected to the external surface of communication assembly 2, the other end of stirring blade 3 is in contact with the inner wall of drying barrel 1;Stirring blade 3 is provided with several material leakage grooves 5 of uniform distribution, the top of stirring blade 3 is smooth surface, the bottom of stirring blade 3 is provided with flow guide coil 4, and the two ends of flow guide coil 4 are respectively communicated with the two ends of communication assembly 2;Due to the setting of stirring blade 3, it can continuously turn the mixed material in drying barrel 1 under the cooperation of communication assembly 2 and drying barrel 1, and under the action of gravity, the mixed material can slide on the top of heat-conducting stirring plate 31, i.e. directly absorb heat, accelerate the moisture in material particle, so as to improve drying efficiency;

[0028] The stirring blade 3 comprises a heat-conducting stirring plate 31 fixedly connected to the outer surface of the communicating assembly 2. The heat-conducting stirring plate 31 is spiral-shaped. The left and right ends of the heat-conducting stirring plate 31 and the end away from the communicating assembly 2 are provided with scraping heads 32 connected to each other. The outer side of the scraping head 32 is in close contact with the inner wall of the drying barrel 1. Since the heat-conducting stirring plate 31 is spiral-shaped, when it rotates with the communicating assembly 2, it can push the material along the axial direction under the cooperation of the drying barrel 1, so that the material is stirred by the heat-conducting stirring plate 31 to move radially, and at the same time, the material can move axially under the cooperation of the spiral shape. Under the cooperation of gravity and the inclined drying barrel 1, the radially and axially moving material can move reversely, so as to achieve the effect of continuous stirring, thereby effectively improving the mixing efficiency. Since the scraping head 32 is provided, the heat-conducting stirring plate 31 can better push the material along the inner wall of the drying barrel 1, and the situation that the material is blocked between the scraping head 32 and the drying barrel 1 is reduced. The inclined leakage groove 5 not only ensures that the material slides along the heat-conducting stirring plate 31 and then flows out, but also offsets the situation that the material collides with the air pressure buffer assembly 21 when falling under the action of inertia, so as to increase the falling time of the formed material thin surface in the drying barrel 1, thereby improving the drying efficiency.

[0029] As shown in Figure 3 and Figure 5 and shown, the leakage grooves 5 are uniformly distributed on the heat-conducting stirring plate 31, one of the leakage grooves 5 near the communicating assembly 2 is connected to the outer surface of the communicating assembly 2, and the two ends of the heat-conducting stirring plate 31 are fixedly connected to the communicating assembly 2.

[0030] As shown in Figure 5 , the flow guide disc pipe 4 at the bottom of the heat-conducting stirring plate 31 is uniformly attached to the heat-conducting stirring plate 31 around the leakage grooves 5, the cross section of the leakage groove 5 is inclined, the distance between the end of the leakage groove 5 extending to the top of the heat-conducting stirring plate 31 and the communicating assembly 2 is less than the distance between the end of the leakage groove 5 extending to the bottom of the heat-conducting stirring plate 31 and the communicating assembly 2, and the inner wall of the leakage groove 5 is smooth.

[0031] As shown in Figure 3 , the communicating assembly 2 comprises an air pressure buffer assembly 21 penetrating the middle of the drying barrel 1. The two ends of the air pressure buffer assembly 21 extend to the outside of the drying barrel 1 and are fixedly connected with one rotating sealing sleeve 22.

The two ends of the outer surface of the air pressure buffer assembly 21 are fixedly sleeved with a positioning bearing 24 between the drying barrel 1 and the rotating sealing sleeve 22. Due to the arrangement of the rotating sealing sleeve 22, the driving mechanism can drive the communicating assembly 2 and the stirring blade 3 to rotate through the transmission belt, and at the same time, it can ensure that the air pressure buffer assembly 21 is driven to rotate without being limited by the communicating pipe 23.

[0032] As shown in Figure 6 and Figure 7As shown in the figure, the air pressure buffer assembly 21 comprises a rotating support pipe 211 fixedly connected to the drying barrel 1 and the middle part of the heat-conducting stirring plate 31, the middle part of the rotating support pipe 211 is provided with a communication cavity 212, the two ends of the rotating support pipe 211 are provided with a plurality of communication holes 213, one end of the communication hole 213 is communicated with the communication cavity 212, and the other end of the communication hole 213 is communicated with the flow guide coil 4; due to the arrangement of the communication hole 213, the two ends of the flow guide coil 4 can be communicated with the two ends of the communication cavity 212.

[0033] As shown in the figure, Figure 7 The middle part of the communication cavity 212 is fixedly installed with a pressure sensor 214, the two ends of the pressure sensor 214 are connected with one buffer spring 216, and the two ends of the two buffer springs 216 are connected with one piston 215 sealingly sleeved in the communication cavity 212; due to the arrangement of the pressure sensor 214, when the communication assembly 2 and the flow guide coil 4 are attached with impurities, resulting in reduced flow efficiency or even blockage, the air flow entering the communication pipe 23 does not change the flow rate, the air flow pushes the piston 215 at the air inlet end and presses the corresponding end of the pressure sensor 214 through the buffer spring 216 to issue an alarm; when the extremely rear end structure of the air outlet end communication pipe 23 is blocked, the air flow entering the communication pipe 23 pushes the two pistons 215 under the cooperation of the flow guide coil 4, so that the two ends of the pressure sensor 214 are pressed and an alarm is issued, so that the staff can quickly and accurately overhaul.

[0034] As shown in the figure, Figure 7 The inside of the communication cavity 212 is fixedly sleeved with two limiting rings 217, and the limiting ring 217 is located between the corresponding piston 215 and the communication hole 213; due to the arrangement of the limiting ring 217, the movement of the piston 215 can be limited, so that the piston 215 cannot pass through the communication hole 213 after being pushed by the buffer spring 216, thereby ensuring that the communication cavity 212 can always be communicated with the two ends of the flow guide coil 4 through the communication hole 213.

[0035] As shown in the figure, Figure 1 The side of the drying barrel 1 is provided with an inspection port 6, the outside of the drying barrel 1 is provided with a support frame 7, the two ends of the support frame 7 are fixedly connected with the drying barrel 1, and the two ends of the support frame 7 are connected with the air pressure buffer assembly 21 through the positioning bearing 24; the support frame 7 supports the drying barrel 1 to be in an inclined state, the inclined state of the drying barrel 1 is opposite to the spiral direction of the heat-conducting stirring plate 31, the back of the drying barrel 1 is provided with a driving mechanism, and the driving mechanism is connected with the rotating sealing sleeve 22 through a transmission belt.

[0036] The working principle and use process of the utility model are as follows:

[0037] The plurality of materials to be dried are simultaneously added into the interior of the drying barrel 1, and then the hot air is injected into the flow guide coil pipe 4 through the two communication pipes 23, the rotary sealing sleeve 22 and the air pressure buffer assembly 21, and then flows out to circulate, when the hot air flows along the interior of the flow guide coil pipe 4, the heat inside can be transmitted to the heat-conducting stirring plate 31, so that the heat-conducting stirring plate 31 is heated;

[0038] When the driving mechanism is started, the rotary sealing sleeve 22 is driven to rotate by the transmission belt, the rotary sealing sleeve 22 drives the air pressure buffer assembly 21 to rotate, the air pressure buffer assembly 21 drives the plurality of stirring blades 3 to continuously rotate between the air pressure buffer assembly 21 and the drying barrel 1, the heat-conducting stirring plate 31 rotates and cooperates with the material scraping head 32 to stir the mixed materials between the air pressure buffer assembly 21 and the inner wall of the drying barrel 1, and the mixed materials slide along the surface of the heat-conducting stirring plate 31 under the action of gravity and finally flow out from the material leakage groove 5, forming a thin layer of materials in the drying barrel 1, greatly increasing the contact efficiency of the material particles and the hot air in the drying barrel 1, and greatly improving the mixing efficiency of the materials in the form of a thin layer.

[0039] When the mixed materials slide along the surface of the heat-conducting stirring plate 31, the heat-conducting stirring plate 31 can directly heat the mixed materials, accelerating the evaporation of the water in the mixed materials, thereby improving the drying efficiency.
