Description

Technical Field

[0001] The utility model relates to the technical field of fish oil processing, in particular to a fish oil refining and deodorizing device. Background Technique

[0002] Deodorization is a process of removing odor substances by means of steam distillation under the conditions of high temperature and high vacuum. Deodorization mainly distills and removes low-level aldehydes, ketones, free fatty acids, unsaturated hydrocarbons, etc. Therefore, deodorization can not only remove the odor of grease but also increase the smoke point of grease; when staff use a deodorization tower to refine and deodorize fish oil, the fish oil entering the deodorization tower contains more impurities, which affects the deodorization efficiency of the deodorization tower when distilling and deodorizing the fish oil.

[0003] Therefore, it is necessary to filter and remove impurities from the fish oil before it enters the deodorization tower. With the filtration, a large amount of solid particle impurities accumulate in the filter box and need to be cleaned. Most of the cleaning methods require stopping the liquid inlet and filtration work, and then disassembling the filter box to clean the impurities; it has the disadvantage of being inconvenient to quickly clean and discharge the solid particle impurities without stopping the machine; this kind of shutdown cleaning method requires wasting a lot of shutdown time and reduces work efficiency. Summary of the Invention

[0004] The purpose of the utility model is to provide a fish oil refining and deodorizing device, which has the characteristics of good filtering effect, convenient filter residue cleaning and improved work efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a fish oil refining and deodorizing device, including a deodorization tower, filter boxes are arranged on both the left and right sides of the deodorization tower. A coarse filter screen, a fine filter screen and an activated carbon filter layer are sequentially arranged inside the filter box from top to bottom. A movable rod is movably connected to the bottom end of the filter box, and the movable rod is movably connected to the coarse filter screen, the fine filter screen and the activated carbon filter layer. Three scraping plates are fixedly connected to the outer wall of the movable rod, and the three scraping plates are respectively located above the coarse filter screen, the fine filter screen and the activated carbon filter layer. A plurality of uniformly distributed slag discharge ports are fixedly connected to the left side wall of the filter box, and valve plates are arranged on the outer walls of the plurality of slag discharge ports.

[0006] Guide pipes are communicated with the tops of the two filter boxes, and the other ends of the two guide pipes are communicated through a three-way joint. A valve cavity is arranged inside the three-way joint, and a spherical valve is rotatably connected to the inside of the valve cavity. A right-angle through cavity is opened inside the spherical valve.

[0007] To facilitate the introduction of fish oil, as a preferred fish oil refining and deodorizing device of the utility model, a feed pipe is communicated with the top of the three-way joint, and a booster pump is arranged on the outer wall of the feed pipe.

[0008] In order to drive the spherical valve to rotate, as an optimization of the fish oil refining and deodorizing device of the present utility model, a steering gear is installed on the front end face of the tee joint, and the output end of the steering gear is fixedly connected to the spherical valve.

[0009] In order to introduce fish oil into the deodorizing tower, as an optimization of the fish oil refining and deodorizing device of the present utility model, feeding pipes are fixedly connected to the lower outer walls of the two filter boxes, and the other ends of the two feeding pipes are communicated with the deodorizing tower.

[0010] In order to unidirectionally introduce fish oil, as an optimization of the fish oil refining and deodorizing device of the present utility model, a one-way valve is arranged inside the feeding pipe.

[0011] In order to facilitate slag discharge, as an optimization of the fish oil refining and deodorizing device of the present utility model, a plurality of slag discharge ports are respectively located on the upper end faces of the coarse filter screen, the fine filter screen and the activated carbon filter layer.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The fish oil sequentially passes through the coarse filter screen, the fine filter screen and the activated carbon filter layer. The mesh number of the fine filter screen is greater than that of the coarse filter screen. The coarse filter screen filters large particle impurities, the fine filter screen further filters finer impurities and dirt, and finally other harmful substances are adsorbed and filtered by the activated carbon filter layer, and the filtering effect is good;

[0014] When it is necessary to clean the filter residue in the right filter box, first start the steering gear to drive the spherical valve to rotate, thereby driving the right-angle through cavity to change the rotation direction, so that the fish oil enters the left guide pipe and filter box, so that the fish oil is normally filtered through the left filter box, and the filtered fish oil normally enters the deodorizing tower for deodorization. Subsequently, pull down the handle of the right filter box, and the handle drives the movable rod to move downward, thereby driving a plurality of scraping plates to respectively abut against the upper end faces of the coarse filter screen, the fine filter screen and the activated carbon filter layer. Then rotate the movable rod to drive the plurality of scraping plates to rotate, thereby scraping off the filter residue on the upper ends of the coarse filter screen, the fine filter screen and the activated carbon filter layer. The cleaning is convenient. By quickly and alternately switching the filtering and cleaning methods, it is not necessary to stop the feeding and filtering work, and the purpose of quickly cleaning and removing the filter residue without stopping the machine can be achieved, which greatly saves the downtime and improves the work efficiency.
