Description

Technical Field:

[0001] The utility model relates to the technical field of vibrating screens, and more specifically to a continuous feeding device for a vibrating screen of cake premix. Background Art:

[0002] At present, flour is the main raw material for making cakes. During the process of making cakes, the flour needs to be screened for fineness. The screening is mainly carried out on a vibrating screen. During the specific screening process, it is necessary to manually pour a part of the flour from the inlet of the top protective cover. The flour accumulates in the middle of the top screen mesh of the vibrating screen. After the vibrating screen vibrates for a while, the accumulated flour will disperse and be screened. Then, if more flour is added continuously, it will overflow from the inlet of the protective cover, causing waste, and the screening efficiency is slow. Moreover, when using a vibrating screen to screen flour at present, it is necessary to manually add materials intermittently again and again, resulting in a relatively high labor intensity for personnel. Therefore, it is necessary to design a structure that can continuously feed materials and does not require personnel to repeatedly add materials manually. Summary of the Utility Model:

The vibrating screen 1 includes a base. On the upper side of the base, a number of vertically stacked screen frames are provided. The screen frame is composed of a screen mesh 11 and a screen frame 12 arranged around the screen mesh 11. The mesh number of the screen mesh 11 gradually increases from top to bottom; a protective cover 13 is inserted and fixedly connected to the screen frame 12 at the top of the vibrating screen 1. A feed inlet is formed at the top of the protective cover 13. A vertical hopper 2 is provided above the vibrating screen 1. An inclined discharge pipe 21 is formed at the lower end of the hopper 2;

[0018] A vertical conveying pipe 3 is inserted into the feed inlet of the protective cover 13. An inclined opening 31 is formed on the pipe wall of the upper part of the conveying pipe 3. The lower end of the discharge pipe 21 is fixedly connected to the outer wall of the conveying pipe 3 and communicated with the opening 31; a vertically spiral conveying blade 5 is inserted into the discharge pipe 21. A vertical rotating shaft 4 is inserted and fixedly connected in the middle of the conveying blade 5. The upper end of the rotating shaft 4 extends out of the conveying pipe 3 and is fixedly connected to the rotating shaft of a conveying motor 7 through a coupling 6. The conveying motor 7 is fixed on a cylindrical motor mounting bracket 8. The motor mounting bracket 8 is fixed on the top of the conveying pipe 3; the lower end of the rotating shaft 4 extends out of the conveying pipe 3 and is inserted and fixedly connected with a connector 9. The connector 9 is inserted and fixed with a horizontally erected scraper 10. The scraper 10 is inserted into the top-layer screen frame of the vibrating screen 1 and is close to the screen mesh 11, that is, there is a gap between the lower side edge of the scraper 10 and the screen mesh 11 to prevent the scraper 10 from rotating and wearing the screen mesh 11.

[0019] A connecting pipe 14 communicating with the feed inlet is formed at the top of the protective cover 13. The conveying pipe 3 is inserted into the connecting pipe 14.

[0020] The hole wall of the opening 31 on the conveying pipe 3 and the inner wall of the discharge pipe 21 are in the same inclined cylindrical surface, so that the flour falling from the hopper 2 will not be stuck on the outer pipe wall of the conveying pipe 3.

[0021] The length of the scraper 10 is 5 to 6 times the aperture of the feed inlet on the protective cover 13.

[0022] The central axis of the conveying pipe 3, the central axis of the protective cover 13 and the central axis of the rotating shaft 4 are on the same straight line.

[0023] A circular connecting disk 50 is fixed at the top of the discharge pipe 21. The motor mounting bracket 8 is fixedly connected to the connecting disk 50. The rotating shaft 4 is connected to the connecting disk 50 through a bearing. A limiting sleeve 60 is inserted and fixedly connected to the rotating shaft 4 above the connecting disk 50. The limiting sleeve 60 can abut against the connecting disk 50 to limit the downward movement of the rotating shaft 4.

[0024] A number of hoops 30 are fixedly inserted and sleeved on the upper part of the hopper 2, and connecting lugs 301 are formed on the hoops 30; a support upright 40 is arranged on one side of the vibrating screen 1, and the connecting lugs 301 are fixedly connected to the support upright 40 through bolt assemblies, and the hopper 2 needs to be supported by an external support mechanism.

[0025] Working principle: This structure is a continuous feeding device for a cake premix vibrating screen. The technical point of its continuous feeding device is to arrange a hopper 2 above the vibrating screen 1. The flour to be screened can be added to the hopper 2 at one time, and then the conveying pipe 3 and the conveying blade 4 are used to continuously convey the flour to the vibrating screen 1. A rotatable scraper 10 is arranged in the vibrating screen 1, and the scraper 10 can spread out the flour concentrated in the middle of the scraper 10, so as to utilize the screening mesh holes on the outer ring of the screen 11 to accelerate the screening speed of the screen 11, and thus continuous feeding will not overflow the protective cover 13.
