Description

Technical Field

[0001] The utility model relates to the technical field of grain processing machinery, in particular to a flour humidifying machine. Background Technique

[0002] In the processing of grain powders such as flour, generally, impurities are first screened out, and then small tufts of hair and attached dirt on the surface of the material are cleaned; then, after the purified grain particles are soaked in water for 18 to 72 hours, they will become tough, and the bran is easy to separate from the particles. At this time, the particles can be ground; after rough grinding, a concentrator can be used to retain pure endosperm grains by using different specific gravities. The light bran will float, and the remaining heavier endosperm powder is first flattened by a smooth roller flour mill and ground into fine powder. The fine powder is then separated into types and grades by a multi-layer plane rotary sifting machine.

[0003] In the process of grinding wheat into powder, the semi-finished powder needs to lose moisture and dry, which affects the progress of the next process and the product quality. Even in the subsequent processing process, the processing machinery is prone to phenomena such as machine jamming and locked rotor, resulting in a long downtime for cleaning and low work efficiency. For this reason, we propose a flour humidifying machine to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 and Figure 2, A flour humidifying machine, comprising a machine body 10, an upper cover 20, a motor 30, a mixing assembly 40 and a spraying assembly 50. An opening is formed at the top of the machine body 10, and the upper cover 20 is detachably installed and fixed on the top of the machine body 10 to cover the opening of the machine body 10. A feeding part 21 communicating with the inner cavity of the machine body 10 is formed on the upper cover 20, and a discharge port is formed at the bottom of the machine body 10, so that the user can add grain powders such as flour into the machine body 10 by using the feeding part 21, and can export the humidified powders through the discharge port. The motor 30 is installed on the upper cover 20, and the output end of the motor 30 is drivingly connected to the upper end of the mixing assembly 40, so that the mixing assembly 40 is rotatably arranged in the inner cavity of the machine body 10. The spraying assembly 50 is installed on the upper cover 20, and the output end of the spraying assembly 50 extends into the inner top of the machine body 10. Water and gas can be input into the spraying assembly 50, and water mist can be sprayed into the machine body 10 by using the output end of the spraying assembly 50. When humidifying grain powders such as flour, the materials input through the feeding part 21 can be thrown and dispersed by the rotating mixing assembly 40, and the dispersed materials and the water mist sprayed by the spraying assembly 50 can be mixed and contacted under the agitation of the rotating mixing assembly 40, so as to humidify the powders.

[0024] Refer to Figure 3 , The machine body 10 may include a machine cover 11, a maintenance cover 12, a conical hopper 13 and several support legs 14. The machine cover 11 can be made of steel plates after being bent multiple times and welded into a cover body with a polygonal inner cavity. By setting the cross-section of the inner cavity of the machine cover 11 to be polygonal, it is easier to break up the agglomerated or caked powders during the process of the thrown and dispersed powders contacting the inner wall of the machine cover 11 and the agitation of the mixing assembly 40. An inspection opening communicating with the inner cavity of the machine cover 11 is formed on the outer wall of the machine cover 11. By providing the inspection opening (not shown in the figure), the user can facilitate the cleaning of the mixing assembly 40. A plurality of threaded columns welded and fixed to the machine cover 11 are arranged outside the inspection opening, and a maintenance cover 12 covering the inspection opening is arranged at the inspection opening. In the normal state, the maintenance cover 12 can be fixed and shield the inspection opening by using a plurality of threaded columns to pass through the maintenance cover 12 and be screwed and connected with nuts, so as to prevent the powders from being thrown out during the processing. The conical hopper 13 is fixed at the lower end of the machine cover 11 and communicates with the inner cavity of the machine cover 11. A discharge port is formed at the bottom of the conical hopper 13, and the humidified powders can be exported through the discharge port. Several support legs 14 are welded and fixed to the outer wall of the conical hopper 13, and the support legs 14 can support the whole device on the ground and make the discharge port have a certain space from the ground.

[0025] Refer to Figure 4, a C-shaped cover 22 and an end sleeve 23 can also be fixed to the top of the upper cover 20. The C-shaped cover 22 is used to shield the pipe body in the spraying assembly 50 inside it; the end sleeve 23 can be used to shield the upper end of the connecting shaft 45 in the mixing assembly 40 inside it.

[0026] Refer to Figure 4 , the output end of the motor 30 can be connected with a transmission belt (not shown in the figure). The transmission belt is a common transmission structure in the prior art and generally consists of two transmission wheels and a transmission belt in cooperation. The two transmission wheels can be respectively connected with the output end of the motor 30 and the upper end of the connecting shaft 45 in the mixing assembly 40, so that the mixing assembly 40 as a whole can be driven to rotate. A transmission belt protection cover 31 can be covered outside the transmission belt to shield and protect it.

[0027] Refer to Figure 5 , the mixing assembly 40 can include a rotating cylinder 41, a plurality of stirring blades 42, a plurality of vertical slats 43, an annular slat 44 and a connecting shaft 45. The connecting shaft 45 is fixed at the center of the upper surface of the vertical slat 43 and is used to connect with the motor 30, so that the mixing assembly 40 can be driven to rotate. A plurality of vertical slats 43 are uniformly distributed and fixed at the outer edge of the upper surface of the rotating cylinder 41, and the annular slat 44 is respectively fixedly connected with the upper ends of the plurality of vertical slats 43. A gap through which the material can pass is formed between two adjacent vertical slats 43, so that the powder material can pass through the above gap and continue to fall downward through the gap between the rotating cylinder 41 and the machine cover 11. A plurality of stirring blades 42 are fixedly connected to the outer wall of the rotating cylinder 41, and each stirring blade 42 can be welded or bolted to the outer wall of the rotating cylinder 41 at an angle (the angle with the horizontal plane is 0° to 90°, and 0° and 90° are not included) downward or downward. The plurality of stirring blades 42 are uniformly distributed along the radial and axial directions of the rotating cylinder 41. By changing the distribution ratio of the two types of stirring blades 42 facing different directions, the advancing speed (falling speed) of the powder material can be changed. The powder material fed through the feeding part 21 will fall on the upper surface of the rotating cylinder 41, and under the action of centrifugal force, the powder material will rotate and disperse outward and pass through the gap between two adjacent vertical slats 43 and fall downward. The stirring blades 42 can stir the powder material falling from the top of the rotating cylinder 41 to be evenly mixed with the water mist, and make the powder material be stirred and collide with the inner wall of the machine cover 11 less to reduce caking and agglomeration.

[0028] Refer to Figure 4, the spraying assembly 50 may include a pipe body (not shown in the figure), a water inlet 51, a gas inlet 52, and a plurality of nozzles 53. One ends of the water inlet 51 and the gas inlet 52 facing the pipe body are both connected to the pipe body. The water inlet 51 and the gas inlet 52 can be used to respectively input water and gas into the pipe body, and the water and gas are mixed in the pipe body. The plurality of nozzles 53 are all fixedly connected to the bottom of the pipe body, and the plurality of nozzles 53 are all located above the mixing assembly 40. The nozzles 53 can be used to spray water mist downward, and the water mist is used to humidify the powder material. An adjustment knob can be installed on the top of each nozzle 53, and rotating the adjustment knob can control the opening and closing and the flow rate of the spraying of the nozzle 53.

[0029] In all the solutions mentioned above, for the connection between two components, welding, connection with bolts and nuts, connection with bolts or screws, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
