Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a vacuum drying tank. Background Art

[0002] The vacuum drying tank can quickly extract the vaporized steam when the inside of the tank is evacuated, forming a negative pressure state around the material, so that a large humidity gradient is formed between the inner and outer layers of the material and between the surface and the surrounding medium, accelerating the vaporization speed, thereby achieving the purpose of quickly drying the material.

[0003] After searching, the patent document with publication number CN213363050U discloses a can vacuum dryer, including a can body with closed ends, a heating assembly arranged in the can body, an exhaust pipe fixed on the outer wall of the upper end of the can body, a feeding pipe fixed on the outer wall of the upper end of the can body, and a stirring member arranged on the can body. A base is fixed at the bottom of the can body, and mounting grooves are provided at both ends of the base, and the mounting grooves are connected to the bottom surface of the base. The vacuum dryer can not only improve the flexibility of the dryer, but also stir and turn the material during drying, thereby accelerating the drying efficiency of the material. However, the vacuum dryer still has the following technical problems:

[0004] 1. During stirring, the horizontal rotation of the stirring rod can only make the material flip in the horizontal direction, and the flipping effect in the vertical direction is not good, resulting in very limited improvement in the drying efficiency of the material, and the work efficiency is still low;

[0005] 2. During the material drying process, it is easy to stick to the inner wall of the dryer, making it very difficult to clean the dryer later. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the prior art can only turn the material in the horizontal direction, but the turning effect in the vertical direction is not good, resulting in a very limited improvement in the material drying efficiency. A vacuum drying tank is proposed which can turn the material up and down while stirring and turning the material horizontally, thereby improving the material drying efficiency.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A vacuum drying tank, comprising:

[0009] A tank body, wherein a rotating rod is rotatably mounted inside the tank body, a plurality of collars are mounted on the rotating rod, and each collar is provided with a plurality of stirring rods;

[0010] The flipping mechanism is used to flip the material up and down when the material is horizontally stirred, and includes a rotating shaft installed on the stirring rod.

A plurality of flipping blades are provided on the rotating shaft, and a gear is provided on the rotating shaft.

[0014] Preferably, the cleaning ring is slidably mounted on the inner wall of the tank body.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. The utility model is provided with a turning mechanism. When drying the material, the motor drives the rotating rod to rotate, which further drives a plurality of stirring rods to rotate, and turns the material in the horizontal direction.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 3 , a vacuum drying tank, comprising:

[0025] The tank body 1 has a rotating rod 11 rotatably mounted inside the tank body 1, and a plurality of collars 12 are mounted on the rotating rod 11, and each collar 12 is provided with a plurality of stirring rods 13;

[0026] The turning mechanism 2 is used to turn the material up and down when the material is horizontally stirred, and includes a rotating shaft 21 installed on the stirring rod 13. A motor 22 is provided under the tank body 1. The output shaft of the motor 22 is fixedly connected to the rotating rod 11. A plurality of turning blades 23 are provided on the rotating shaft 21. A gear 24 is provided on the rotating shaft 21. An annular tooth groove 25 is provided inside the tank body 1, and the gear 24 and the annular tooth groove 25 are meshed with each other.

[0027] Among them, two fixed connecting rods 4 are provided on the inner wall of the tank body 1, and several annular tooth grooves 25 are fixedly connected to the fixed connecting rods 4. The fixed connecting rods 4 can ensure that the annular tooth grooves 25 will not move, thereby ensuring that the gear 24 can perform circular motion along the annular tooth grooves 25 and rotate in the process.

[0028] In view of the problem that the prior art can only flip the material in the horizontal direction, but the flipping effect in the vertical direction is not good, resulting in a very limited improvement in the material drying efficiency and still low work efficiency, the utility model sets a flipping mechanism 2. When the material is dried, the motor 22 drives the rotating rod 11 to rotate, further drives a plurality of stirring rods 13 to rotate, and flips the material in the horizontal direction. At the same time, since the gear 24 rotates when performing a circular motion along the annular tooth groove 25, the rotating shaft 21 on each stirring rod 13 rotates, and further under the action of the flipping blades 23, the material is flipped up and down in the vertical direction, thereby further improving the material drying efficiency and greatly improving the work efficiency.

[0029] The anti-sticking mechanism 3 is used to prevent the material from sticking to the inner wall of the tank body 1 during the drying process, and includes a reciprocating screw 31 rotatably installed in the tank body 1, and a cleaning ring 32 is threadedly connected to the reciprocating screw 31. The reciprocating screw 31 and the part of the rotating rod 11 extending above the tank body 1 are respectively provided with a first synchronous wheel 33 and a second synchronous wheel 34, and a synchronous belt 35 is sleeved between the first synchronous wheel 33 and the second synchronous wheel 34.

[0030] The peripheral side wall of the cleaning ring 32 is in contact with the inner wall of the tank body 1 , thereby ensuring the scraping effect of the cleaning ring 32 on the inner wall of the tank body 1 when the cleaning ring 32 is vertically displaced.

[0031] The cleaning ring 32 is slidably mounted on the inner wall of the tank body 1, which limits the cleaning ring 32 so that the cleaning ring 32 can only move vertically.

[0032] The radius of the first synchronous wheel 33 is different from that of the second synchronous wheel 34 , ensuring that the wrap angle between the synchronous belt 35 and the first synchronous wheel 33 and the second synchronous wheel 34 can make the first synchronous wheel 33 and the second synchronous wheel 34 rotate synchronously, preventing the synchronous belt 35 from slipping.

[0033] In view of the problem in the prior art that materials are easily stuck to the inner wall of the dryer during the drying process, making it very difficult to clean the dryer subsequently, the utility model provides an anti-sticking mechanism 3. When the rotating rod 11 rotates to stir and dry the material, the reciprocating screw 31 is driven to rotate through the first synchronous wheel 33, the second synchronous wheel 34 and the synchronous belt 35, so that the cleaning ring 32 performs a reciprocating vertical displacement to scrape off the material stuck to the inner wall of the tank body 1, thereby facilitating the subsequent cleaning of the tank body 1. At the same time, there is no need to provide an additional driving source, thereby saving costs.

[0034] The functional principle of the utility model can be explained through the following operation modes:

[0035] When the material is dried, the motor 22 drives the rotating rod 11 to rotate, further driving the plurality of stirring rods 13 to rotate, and the material is flipped in the horizontal direction. At the same time, since the gear 24 rotates when performing a circular motion along the annular tooth groove 25, the rotating shaft 21 on each stirring rod 13 rotates, and the material is further flipped up and down in the vertical direction under the action of the flipping blades 23, thereby improving the drying efficiency of the material.

[0036] When the rotating rod 11 rotates to stir and dry the material, the reciprocating screw 31 will also be driven to rotate through the first synchronous wheel 33, the second synchronous wheel 34 and the synchronous belt 35, so that the cleaning ring 32 performs reciprocating vertical displacement to scrape off the material adhering to the inner wall of the tank body 1, so as to facilitate the subsequent cleaning of the tank body 1.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
