Description

TECHNICAL FIELD

[0001] The application relates to the technical field of thin film drying, in particular to a single-cone thin film rapid drying device. BACKGROUND

[0002] A thin film is a thin layer material with a specific thickness and structure formed by depositing micro-particles (such as atoms, molecules or ions) on the surface of a substrate through physical or chemical methods;

[0003] In the production process of the thin film, the thin film particles need to be dried to remove solvents or moisture, so as to ensure the stability of the final performance;

[0004] For example, the patent with the publication number CN217817916U specifically discloses a single-cone vacuum dryer with internal heating of a spiral belt. When the dryer is in use, the worker first connects the air inlet pipe to the air outlet end of the designated air heating device. The hot air first enters the circulating pipe through the air inlet pipe, heats the inner wall of the drying tank through the circulating pipe, and then is sent to the stirring pipe through the air inlet box body. The hot air is sent to the air outlet box body through the stirring pipe, and is sent to the designated position through the exhaust pipe connected with the air outlet box body, so as to heat the drying tank, and the spiral belt is started by the stirring mechanism to stir the material, so that the drying is more uniform.

[0005] Since the spiral belt is in the stirring process, the material may be embedded in the gap between the spiral belt and the inner wall of the drying tank, thereby intensifying the friction between the spiral belt and the inner wall of the drying tank, and thus wear may be caused, so that after a long time of use, the gap between the edge of the spiral belt and the inner wall of the tank body may be too large, thereby affecting the subsequent stirring efficiency.

[0045] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0046] Example 1: As Figures 1-2 As shown, this application provides a single-cone film rapid drying apparatus, including an equipment frame 1, on which a drying component 2 is disposed. The drying component 2 is used for drying film (film particles), specifically:

[0047] The drying assembly 2 includes a tank 24 fixedly mounted on the equipment frame 1. The tank 24 has an inner liner 27 inside and a tank cover 21 on the tank 24. The tank cover 21 has a feed pipe 201, and the inner liner 27 has a cavity inside so that film particles can be fed into the cavity of the inner liner 27 through the feed pipe 201 for subsequent processing.

[0048] A suction pipe 202 is arranged on the tank cover 21, which can be connected with an external suction pump, and the outer part of the inner container 27 is arranged with a circulating pipe 25, both ends of which can be connected with external heating equipment, and an exhaust pipe 22 is arranged on the tank cover 21;

[0049] Further, when the film particles are dried, the inside of the tank body 24 can be subjected to air suction treatment under the driving of the suction pump, so that the inside of the tank body 24 is in a state of relative vacuum, and the heating medium is circulated into the circulating pipe 25 to heat the inner container 27, thereby drying the film particles, and the evaporated water vapor can be discharged through the exhaust pipe 22;

[0050] An exhaust pipe is arranged at the bottom of the tank body 24, and an air inlet pipe (not shown in the figure) and a discharge valve 26 are arranged on the exhaust pipe, the air inlet pipe can be connected with external air charging equipment, which can inject nitrogen into the inside of the tank body 24 through the air inlet pipe, thereby injecting nitrogen during drying to reduce the entry of oxygen and further oxidation reaction with the film particles, and after drying is completed, the discharge valve 26 can be opened to discharge the film particles;

[0051] It should be noted that the tank body 24 is provided with a sampling valve 23, so that during the drying process, the material can be extracted through the sampling valve 23 to observe the drying degree of the material;

[0052] A stirring assembly 3 is arranged on the tank cover 21, which is used for stirring operation of the film particles;

[0053] As shown in Figures 3-6 The stirring assembly 3 includes a mounting frame 31 fixedly installed on the tank cover 21, a stepping motor 4 fixedly installed on the mounting frame 31, an output end of the stepping motor 4 fixedly installed with a driving gear 41, and a sleeve 43 bearing installed on the tank cover 21, the bottom end of the sleeve 43 extending into the cavity of the inner container 27, and a plurality of cross rods 36 fixedly arranged on the sleeve 43, and a plurality of cross rods 36 are commonly provided with a screw blade 47, which is in a spiral shape;

[0054] A driven gear 42 is fixedly sleeved at the top end of the sleeve 43, which is in meshing connection with the driving gear 41, and under the driving of the stepping motor 4, the driven gear 42 is driven to rotate by the driving gear 41, and the sleeve 43 is driven to rotate, and the screw blade 47 is driven to rotate, so as to stir the film particles in the inner container 27, accelerate the drying, and make the drying more uniform;

[0055] In summary, in use, the film particles are fed into the inner container 27 through the feeding pipe 201, the air in the inner container 27 is pumped out by starting the air pumping device, the inner container 27 is heated by starting the heating device, the step motor 4 is started to drive the spiral blade 47 to rotate through the sleeve pipe 43 to stir the film particles, thereby accelerating the drying process, at the same time, the exhaust port exhausts the water vapor evaporated during drying, and the air charging device is started to introduce nitrogen into the inner container 27 to prevent the film particles from reacting with oxygen. After stirring is completed, the discharge valve 26 is opened to discharge the film particles.

[0056] Example two: Although the above process can achieve the drying of the film particles, the spiral blade 47 and the inner wall of the inner container 27 have a certain working gap in the initial state, and the spiral blade 47 may be worn during stirring, thereby causing the working gap between the spiral blade 47 and the inner wall of the inner container 27 to increase after long-term use, which may affect the subsequent stirring efficiency.

[0057] As shown in Figures 2-8 To solve this problem, the plurality of cross rods 36 and the sleeve pipe 43 are separated, and the spiral blade 47 is divided into a left blade group 37 and a right blade group 39 along the axis of the sleeve pipe 43 from left to right. Figure 6 The left blade group 37 has a plurality of first blades, the right blade group 39 has a plurality of second blades, and a connecting rod 38 is arranged between the plurality of first blades and the plurality of second blades to connect the plurality of first blades and the plurality of second blades into two whole bodies.

[0058] The left blade group 37 and the right blade group 39 are arranged in sequence and staggered, and the left blade group 37 is connected with one of the plurality of cross rods 36, and the right blade group 39 is connected with another of the plurality of cross rods 36.

[0059] The mounting frame 31 is fixedly installed with a gas cylinder 32, the output end bearing of the gas cylinder 32 is installed with a top cover 33, the bottom of the top cover 33 is fixedly installed with a stirring rod 34, the stirring rod 34 is slidingly arranged in the inside of the sleeve pipe 43, a clamping block 45 is arranged on the outer circle of the stirring rod 34, and a key groove 44 adapted to the clamping block 45 is arranged in the inside of the sleeve pipe 43.

[0060] Further, when the sleeve pipe 43 rotates, the stirring rod 34, the top cover 33 and the stirring rod 34 can be driven to rotate under the cooperation of the clamping block 45 and the key groove 44, and the top cover 33 and the stirring rod 34 can be driven to move vertically in the inside of the sleeve pipe 43 under the driving of the gas cylinder 32.

[0061] The inside of the top cover 33 is provided with an adjusting part, which comprises a servo motor (not shown in the figure) fixedly arranged inside the top cover 33, an output end of the servo motor is provided with a rotating rod 5, and a through hole is arranged at the center of the stirring rod 34, the rotating rod 5 is located inside the through hole, and two groups of disc plates 51 are fixedly arranged on the rotating rod 5, the two groups of disc plates 51 are symmetrically arranged along the axis of the rotating rod 5, and arc grooves 52 are formed in the two groups of disc plates 51;

[0062] With reference to the above Figure 7 , a sliding rod 56 is slidably arranged in the arc groove 52, the sliding rod 56 is fixedly provided with a sliding block 35, the sliding block 35 is slidably arranged on the stirring rod 34, one end of the two groups of sliding blocks 35 extends out of the stirring rod 34, and the two groups of sliding blocks 35 are fixedly connected with the cross rod 36;

[0063] It should be noted that the two groups of arc grooves 52 are oppositely arranged, and the arc groove 52 can be divided into a right end and a left end along Figure 7 the direction from right to left, the right end is close to the center of the disc plate 51, and the left end is away from the center;

[0064] Further, when the disc plate 51 rotates, the sliding rod 56 can move from the right end to the left end or from the left end to the right end, and simultaneously drive the cross rod 36 away from or close to the center of the disc plate 51 (i.e. drive the cross rod 36 close to or away from the inner wall of the inner container 27) through the sliding block 35;

[0065] In order to facilitate the description, the right end of the arc groove 52 is defined as the first stationary point 53, the left end of the arc groove 52 is defined as the second stationary point 54, and a touch sensor 55 is arranged in the inside of the two groups of disc plates 51, the trigger part of the touch sensor 55 is located at one end of the arc groove 52 close to the second stationary point 54;

[0066] In the initial state, the sliding rod 56 is in contact with the trigger part of the touch sensor 55, at this time, the left blade group 37, the right blade group 39 and the bottom blade 49 form a spiral belt blade 47, and the positions of the left blade group 37 and the right blade group 39 at this time are defined as the working state;

[0067] When stirring is needed, the stepping motor 4 can be started, the sleeve 43 is driven to rotate through the driving gear 41 and the driven gear 42, at this time, the sleeve 43 drives the stirring rod 34 to rotate through the clamping block 45 and the key groove 44, so as to drive the top cover 33 and the spiral belt blade 47 to rotate;

[0068] When the working gap wears greatly, the servo motor can be started to drive the rotating rod 5 to rotate and drive the two groups of discs 51 to rotate. At this time, with the rotation of the disc 51, the slide rod 56 slides in the arc groove 52 from the triggering part of the contact sensor 55 to the second stationary point 54, thereby driving the sliding block 35 away from the center of the disc 51, and driving the left blade group 37 and the right blade group 39 to approach the inner wall of the inner container 27 through the cross rod 36 (that is, the left blade group 37 and the right blade group 39 are away from each other), so as to compensate the working gap and make it meet the specified gap, continue to drive the stirring rod 34 to rotate through the clamping block 45 and the key groove 44, thereby driving the left blade group 37 and the right blade group 39 to rotate, and the position of the left blade group 37 and the right blade group 39 at this time is defined as the compensation state.

[0069] At the same time, when the left blade group 37 and the right blade group 39 move to the maximum position and the working gap is still too large, the air cylinder 32 is started to drive the stirring rod 34 to move in the sleeve 43, thereby driving the left blade group 37 and the right blade group 39 to move downward through the sliding block 35 and the cross rod 36, and further compensating the working gap.

[0070] With reference to the above Figure 2 , in order to avoid interference between the bottom blade 49 and the bottom of the inner container 27, a support rod 48 is arranged on the bottom blade 49, which is fixedly connected with the sleeve 43, so that the bottom blade 49 does not move during the adjustment of the left blade group 37 and the right blade group 39;

[0071] It should be noted that a groove 46 adapted to the clamping block 45 is arranged through the sleeve 43, so as to avoid interference when the clamping block 45 moves downward;

[0072] When feeding, the servo motor can be started to drive the disc 51 to rotate through the rotating rod 5, so that the slide rod 56 slides from the triggering part of the contact sensor 55 to the first stationary point 53, thereby driving the left blade group 37 and the right blade group 39 to approach each other, so that the working gap becomes larger, thereby making the film particles accumulate along the inner wall of the tank body 24 to the bottom when feeding the inner container 27 through the feeding pipe 201, so that the film particles are more uniformly accumulated, and the position of the left blade group 37 and the right blade group 39 at this time is defined as the feeding state, so as to facilitate feeding;

[0073] And when the left blade group 37 and the right blade group 39 are in the compensation state and the gathering state, there is a certain gap between the left blade group 37 and the right blade group 39, which does not affect the stirring operation of the left blade group 37 and the right blade group 39.

[0074] The above-described specific embodiments further illustrate the technical problems solved by the present application, technical solutions and beneficial effects, and it should be understood that the above-described are only specific embodiments of the present application and are not intended to limit the present application, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
