Technical Field

[0001] The utility model relates to the technical field of material receiving, in particular to a material receiving device for a centrifugal spray dryer. Background Art

[0002] A centrifugal spray dryer mainly uses a rotating nozzle to spray liquid materials into fine droplets. Under the action of centrifugal force, the droplets are subjected to an outward inertial force, which can throw the droplets out and make them quickly disperse in hot air. In the air flow, the water on the surface of the droplets begins to evaporate. When all the water in the droplets has evaporated, dry powder or granules are obtained. As Figure 1 、 Figure 2 shown, it is a centrifugal spray dryer in the prior art. The finally obtained powder or granules are collected in the material bucket 1. The discharge pipe 2 of the centrifugal spray dryer is arranged vertically. Two inverted L-shaped grooves 21 are provided on the side wall of the discharge pipe 2. The two L-shaped grooves 21 are centrosymmetric. Two cylinders 11 and two handles 12 are provided on the side wall of the material bucket 1. The outer wall of the top of the material bucket 1 is closely attached to the inner wall of the discharge pipe 2. The cylinder 11 is matched in the corresponding L-shaped groove 21. The problem is that the capacity of the material bucket 1 is limited. Workers need to regularly remove the material bucket 1, pour the materials in the material bucket 1 into other containers, and then assemble the material bucket 1 to the bottom of the discharge pipe 2. This process relies on manual labor and needs to be improved. Content of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a material receiving device for a centrifugal spray dryer, in which the material bucket and the discharge pipe can be automatically docked and separated, and the material bucket can also automatically discharge materials.

[0004] To achieve the purpose of the utility model, the following scheme is proposed:

In this embodiment, the material barrel 1 is detachably installed in the first U-shaped plate 51. The first U-shaped plate 51 is slidably matched with the second U-shaped plate 52 up and down. The lifting assembly 3 is arranged in the second U-shaped plate 52. The top of the lifting assembly 3 is connected to the first U-shaped plate 51. The power source of the lifting assembly 3 is driven by a cylinder, an oil cylinder or a hydraulic pressure, and is used to adjust the height of the first U-shaped plate 51 and the material barrel 1, so as to lift the material barrel 1 and dock it with the discharge pipe 2. The second U-shaped plate 52 is rotatably arranged in the third U-shaped plate 53, and the output shaft of the motor 4 is used to drive the second U-shaped plate 52.

[0023] When receiving materials, the material barrel 1 can be lifted and docked with the discharge pipe 2 by using the lifting assembly 3; when pouring materials, first use the lifting assembly 3 to lower the material barrel 1 and separate it from the discharge pipe 2, and then use the motor 4 to drive the second U-shaped plate 52, so that the second U-shaped plate 52, the first U-shaped plate 51 and the material barrel 1 rotate as a whole, so as to pour the materials in the material barrel 1 into another container. This embodiment realizes the automatic docking and separation of the material barrel 1 and the discharge pipe 2, and also realizes the automatic pouring of the material barrel 1.

[0024] The specific connection method between the first U-shaped plate 51 and the second U-shaped plate 52 is as follows: As Figure 4 shown, the outer wall of the first U-shaped plate 51 is closely attached to the inner wall of the second U-shaped plate 52. A guide post 511 is respectively arranged on the two outer walls of the first U-shaped plate 51, and a vertical groove 521 is arranged at the corresponding position of the second U-shaped plate 52. The guide post 511 is slidably matched in the corresponding vertical groove 521.

[0025] The specific connection method between the material barrel 1 and the first U-shaped plate 51 is as follows: As Figure 5 、 Figure 6As shown in the figure, a cross plate 513 is provided between the two inner walls of the first U-shaped plate 51. A support plate 512 is provided on each of the two inner walls of the first U-shaped plate 51. The cross plate 513 is located below the support plate 512. The material barrel 1 is installed in the first U-shaped plate 51 through a positioning member. A base 13 is provided at the bottom of the material barrel 1. The inside of the base 13 is hollow. A through hole 131 is provided at the bottom of the base 13. The positioning member includes a base 61, two symmetrically arranged positioning plates 62, a screw 63 and a regulating plate 64. The base 61 is fixedly provided in the first U-shaped plate 51, and the base 61 is located above the support plate 512. A circular groove 611 is provided at the top of the base 61. A through groove 612 penetrating the base 61 is provided at the bottom of the circular groove 611. The inner diameter of the through groove 612 is smaller than the inner diameter of the circular groove 611. The base 13 is matched in the circular groove 611. The screw 63 is threadedly penetrated through the cross plate 513. The top end of the screw 63 is rotatably connected to the regulating plate 64. A knob 65 is provided at the bottom end of the screw 63. A column 514 is provided on the support plate 512. The positioning plates 62 are located in the through groove 612 and the through hole 131. The bottom end of the positioning plate 62 is rotatably connected to the regulating plate 64. A V-shaped groove 621 is provided on the positioning plate 62. The included angle of the V-shaped groove 621 is an obtuse angle. In the up-down direction, the V-shaped groove 621 is vertically arranged first and then inclined downward. The included angle directions of the two V-shaped grooves 621 face away from each other. The column 514 is slidably matched in the corresponding V-shaped groove 621. The top end of the positioning plate 62 is set as a hook shape for hooking the base 13.

[0026] The principle is as follows: In Figure 5 this perspective, at this time, the column 514 is located at the top end of the V-shaped groove 621, and the top ends of the two positioning plates 62 both hook the base 13; when it is necessary to clean the material barrel 1, the staff rotates the knob 65 to prompt the regulating plate 64 and the two positioning plates 62 to move upward simultaneously. The column 514 gradually moves from the vertical section of the V-shaped groove 621 to the inclined section. When the column 514 moves along the inclined section, the column 514 will prompt the positioning plate 62 to rotate, so that the top ends of the two positioning plates 62 gather together. After the material barrel 1 loses the restriction of the positioning plate 62, the staff can take out the material barrel 1 upward; when installing the material barrel 1, put the material barrel 1 into the circular groove 611, and the staff rotates the knob 65 to prompt the regulating plate 64 to move downward. The top ends of the two positioning plates 62 first expand and then hook the base 13 downward, thereby fixing the material barrel 1.

[0027] In order to further improve the stability of the regulating plate 64 during the up-down movement, the following measures are taken in this embodiment: A cross beam 613 is provided in the through groove 612, and a spring is provided between the cross beam 613 and the regulating plate 64.

[0028] The above embodiments are only used to illustrate the technical ideas and features of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
