Description

Technical Field

[0001] The utility model relates to the technical field of stirring and conveying devices, in particular to a stirring and conveying device for preservative production. Background Art

[0002] Preservatives are food additives that inhibit microbial activity and prevent food spoilage. During production, preservatives are mixed with parahydroxybenzoic acid and propanol, then heated to dissolve and mix. After processing, the preservatives are transported to subsequent equipment for further processing.

[0003] The preservative production stirring and conveying equipment currently on the market usually heats various raw materials and puts them into a tank for stirring. The mixed raw materials are then transported to other processing steps through a transmission device to realize the production process of the preservative. When multiple raw materials are processed in the tank, the stickiness generated when the raw materials are mixed will cause the raw materials to stick to the inside of the tank and be inconvenient to handle. The general handling method is to open the tank after the raw materials are mixed for manual handling, which not only delays production efficiency, but also makes it inconvenient to handle the raw materials that stick to the inside of the tank for a long time. Therefore, a stirring and conveying device for preservative production is proposed to solve the above problems. Utility Model Content

[0024] It should be noted that the annular ring on the annular protective frame 9 can prevent the raw materials from entering the tank body 1 through the feed hopper 2 and not entering the top of the annular protective frame 9. The auger equipment 6 is a public technology known in the prior art, and its working principle and specific specifications and models will not be further elaborated in this article. The auger equipment 6 is used to transport the mixed materials through the transport pipe 5 to other processes.

[0025] Specifically, when it is necessary to use a stirring and conveying device to mix and transport the preservative raw materials, the various raw materials can be poured into the interior of the tank body 1 through the feed hopper 2, and then the various raw materials inside the tank body 1 are mixed and processed through the stirring structure 8. After the processing, the raw materials can also be opened by opening the discharge valve 7 to allow the raw materials to fall into the interior of the transport pipe 5, and then the auger equipment 6 is used to transport the mixed raw materials to the end of the pipeline and enter other processing areas. When there are raw materials remaining on the inner wall of the tank body 1, the scraping structure 10 can also be used to hang down the raw materials remaining on the inner wall of the tank body 1, thereby achieving the purpose of cleaning the raw materials in the tank body.

[0026] In an optional embodiment, the stirring structure 8 includes a reduction motor 801, a transmission rod 802 and a driving gear 805. The reduction motor 801 is fixedly mounted on the top of the top cover 11, and the output shaft of the reduction motor 801 passes through the top of the top cover 11 and extends to its bottom. The driving gear 805 is fixedly connected to the output shaft of the reduction motor 801. There are three transmission rods 802.

[0027] It should be noted that the three transmission rods 802 can be spaced apart according to the diameter of the tank body 1 to achieve a wider range of mixing effects.

[0028] Specifically, when the raw materials inside the tank body 1 need to be mixed, the reduction motor 801 can be turned on, and the driving gear 805 connected to the output shaft of the reduction motor 801 drives the driven gear 804 to rotate. Since the driven gear 804 is set on the transmission rod 802, the transmission rod 802 drives the stirring blade 803 to rotate to achieve the effect of mixing and stirring multiple preservative raw materials.

[0029] In an optional embodiment, the wall scraping structure 10 includes a servo motor 1001, a threaded rod 1002, a lifting frame 1003 and a sheet scraper 1004. The servo motor 1001 is arranged at the top of the annular protective frame 9, one end of the threaded rod 1002 is connected to the output end of the servo motor 1001, and the other end of the threaded rod 1002 passes through the top of the annular protective frame 9 and extends to its bottom. The lifting frame 1003 is sleeved on the outer surface of the threaded rod 1002. The lifting frame 1003 is composed of a central circular disk and three connecting rods. The ends of the three connecting rods away from the circular disk are all connected to the top of the lifting frame 1003 by bolts, and the sheet scraper 1004 is fixed to the bottom of the lifting frame 1003 by bolts.

[0030] It should be noted that the circular disk in the middle of the lifting frame 1003 is threadedly connected to the threaded rod 1002, and two sliders are provided on the side of the sheet scraper 1004 close to the inner wall of the tank body 1.

[0031] Specifically, when it is necessary to drop the residual raw materials inside the tank body 1, the servo motor 1001 can also drive the threaded rod 1002 to rotate, so that the lifting frame 1003 threadedly connected to the threaded rod 1002 can be lifted and lowered on the threaded rod 1002, and the lifting frame 1003 is connected to the sheet scraper 1004, so that the sheet scraper 1004 can drop the residual raw materials inside the tank body 1.

[0032] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
