Description

Technical Field

[0001] The present application relates to the technical field of sodium formate drying, and in particular to a sodium formate drying device. Background Art

[0002] Sodium formate can be used as a disguised acid, catalyst and stabilizer. It is hygroscopic and easy to deliquesce. It is easy to clump after being damp, which causes some inconvenience to the use of sodium formate. However, sodium formate does not change its properties after being damp. Sodium formate will decompose into sodium oxalate and hydrogen at high temperature to produce sodium carbonate.

[0003] With respect to the above-mentioned related technologies, the inventors believe that sodium formate is easily affected by moisture during storage and transportation. In order to facilitate subsequent use, it is often necessary to dry the damp and agglomerated sodium formate. Most of the existing sodium formate drying equipment has a relatively simple structure, uneven material feeding, and is prone to excessive one-time feeding. Since sodium formate is affected by moisture and agglomerates, the drying efficiency of general sodium formate drying equipment is not high. Therefore, a sodium formate drying equipment is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a sodium formate drying device. Figure 1-3 A sodium formate drying device comprises a base 1, a drying drum 2 and a feed box 4. The top outer wall of the base 1 is rotatably connected to a plurality of driving wheels 12. The drying drum 2 is rollingly connected to the top outer wall of the plurality of driving wheels 12. The inner wall of the drying drum 2 is fixedly connected to a threaded conveying blade 10 for feeding. The inner wall of the drying drum 2 is fixedly connected to a plurality of material-diverting plates 11 for diverting. The feed box 4 is fixedly installed above the base 1 through a bracket 3. The feed box 4 is located directly above the drying drum 2. The inner wall of the feed box 4 is fixedly connected to a plurality of material-diverting plates 11 for diverting. It is equipped with a crushing and feeding mechanism, which includes a male screw 5 and a female screw 6 rotatably connected to the inner wall of the feeding box 4, the male screw 5 is meshed with the female screw 6, and a servo motor 7 is fixedly installed on the outer wall of one end of the feeding box 4. The output shaft of the servo motor 7 passes through the feeding box 4 and is fixedly connected to one end of the male screw 5. A hot air generator 16 is installed on the top outer wall of the base 1, and the exhaust pipe of the hot air generator 16 is connected to an air shower pipe 15. The end of the air shower pipe 15 away from the hot air generator 16 extends into the middle inner cavity of the drying drum 2.

[0021] The plurality of material-shifting plates 11 are evenly distributed on the inner wall of the drying drum 2 in a circumferential array with equal spacing, and the plurality of material-shifting plates 11 penetrate the threaded conveying blades 10 .

[0022] A feeding hopper 8 for adding materials is provided on the top outer wall of the feed box 4 near the servo motor 7 .

[0023] A discharge pipe 9 for unloading is arranged on the bottom outer wall of the feed box 4 away from the servo motor 7 . The discharge pipe 9 is connected to the inner cavity of the feed box 4 , and one end of the discharge pipe 9 away from the feed box 4 extends into the inner cavity of the drying drum 2 .

[0024] Two driving motors 13 are fixedly mounted on the top outer wall of the base 1 , and the output shafts of the two driving motors 13 are fixedly connected to two of the driving wheels 12 .

[0025] A fixing frame 14 is fixedly connected to the top outer wall of the base 1 . One end of the air shower pipe 15 away from the hot air generator 16 extends out of the drying drum 2 and is fixedly connected to the base 1 through the fixing frame 14 .

[0026] The implementation principle of the sodium formate drying device of the embodiment of the present application is as follows: when in use, a large amount of sodium formate to be dried can be added to the feed hopper 8 at one time, and the servo motor 7 is started. The output end of the servo motor 7 drives the male screw 5 to rotate, and the male screw 5 drives the female screw 6 to rotate relatively by meshing with the female screw 6, so as to crush and extrude the sodium formate in the feed hopper 8, and evenly feed the material. After the damp and agglomerated part of the sodium formate is crushed, it is convenient for subsequent drying operations, and the contact area between the sodium formate and the air can be increased. When the sodium formate is squeezed and transported into the discharge pipe 9 by the male screw 5 and the female screw 6, the sodium formate is introduced into the drying drum 2 through the discharge pipe 9 for drying;

[0027] The hot air generator 16 and the two driving motors 13 are started at the same time. When the hot air generator 16 is started, the external air is heated and blown into the air shower pipe 15. The air shower pipe 15 sprays the hot air evenly into the inner cavity of the drying drum 2. When the driving motor 13 is started, the two driving wheels 12 are driven to rotate. At this time, the drying drum 2 located on the multiple driving wheels 12 is driven to rotate. When the drying drum 2 rotates, the threaded conveying blades 10 and the material-diverting plates 11 are driven to rotate. The threaded conveying blades 10 can slowly convey the sodium formate, thereby increasing the walking path length of the sodium formate. When the multiple material-diverting plates 11 rotate with the drying drum 2, the sodium formate is continuously diverted, so that the sodium formate is continuously turned over and evenly contacted and dried with the hot air blown into the drying drum 2 by the hot air generator 16 through the air shower pipe 15, which not only ensures the drying effect, but also improves the drying efficiency. The thoroughly dried sodium formate will be discharged and collected from the discharge end of the drying drum 2.
