Description

Technical Field

[0001] The invention relates to the technical field of edible oil production, in particular to a filtering and cleaning device for edible oil production. Background Art

[0002] Edible oil refers to animal or plant fats used in the process of making food. Common edible oils are mostly vegetable oils. During the production and processing of vegetable oils, they are generally made by pressing or leaching. Among them, edible oils processed by pressing may still contain some residues in the oil after pressing, and need to be filtered and other treatments to improve the quality of the oil.

[0003] When the edible oil filtering equipment is working, more filter residue will accumulate on the filter structure, which may easily cause the filter structure to be blocked and affect the filtering efficiency. Patent application number 201822221165.8 is a filtering and cleaning device for edible oil, whose structure mainly includes an oil tank and an oil outlet at the bottom of the oil tank. A filter cleaning plate is arranged below the oil outlet. The filter cleaning plate includes a fixed frame and a filter net inside it. A scraper is arranged on the top of the filter cleaning plate and connected to a telescopic rod, and a slag box is arranged on one side. When a lot of filter residue accumulates on the filter net, the scraper can be moved by the telescopic rod to push the filter residue on the filter net into the slag box, avoiding manual cleaning of the filter residue and speeding up work efficiency.

[0004] However, after cleaning the filter residue on the filter screen, the above-mentioned equipment directly pushes the filter residue into a residue box for collection. The filter residue usually contains a lot of oil, which is directly discharged, resulting in a waste of the oil.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0050] Embodiment 1

[0051] Please refer to the accompanying drawings, the present invention provides a technical solution:

[0053] A horizontal fixed plate 300 is fixed in the middle of the upper inner cavity of the oil filter box 100 along the front-to-back direction, a circular rotating filter plate 400 is provided in the middle of the inner cavity, two oil collecting buckets 102 are symmetrically fixed in the lower part, an oil outlet groove 103 is fixed in the middle of the bottom of the oil collecting bucket 102, a filter bag 104 is installed on the outer side of the bottom of the oil outlet groove 103, and extrusion components are provided on both sides of the corresponding filter bag 104 in the collection box 200;

[0054] The rotating filter plate 400 is rotatably connected to the side wall of the oil filter box 100 through a rotating assembly, and an inner retaining structure and an outer retaining structure are provided on the rotating filter plate 400, and an annular filtering area is formed between the inner retaining structure and the outer retaining structure. A plurality of oil filter holes 401 are evenly provided at positions corresponding to the annular filtering area on the rotating filter plate 400, and the bottom ends of the two oil inlet pipes 101 are located inside the annular filtering area, and are located on the left and right sides respectively;

[0055] like Fig.10 As shown, two arc-shaped push plates 708 are symmetrically arranged in the middle of the top surface of the rotating filter plate 400, two horizontal first push rods 703 are symmetrically fixed on the rear push plate 708, and two horizontal second push rods 704 are symmetrically arranged on the two front push plates 708. A limit slide 306 is fixed at a corresponding position at the bottom of the fixed plate 300, and the first push rod 703 and the second push rod 704 are respectively slidably connected to the limit slide 306 at the corresponding position, as shown in FIG. Fig. 9 As shown,

[0056] A driving assembly is provided in the middle of the bottom of the fixing plate 300, and transmission assemblies are symmetrically connected to the front and rear sides of the driving assembly, and the two transmission assemblies are respectively connected to the first push rod 703 and the second push rod 704;

[0057] The front and rear sides of the bottom of the fixed plate 300 are respectively provided with filter pressing mechanisms at the inner positions corresponding to the annular filter area, and the two filter pressing mechanisms correspond to the positions of the two push plates 708, respectively. The front and rear sides of the oil filter box 100 are respectively provided with a feed trough 106 at the bottom positions corresponding to the rotating filter plate 400, and the bottom of the feed trough 106 is inclined downward to the outside, such as Figure 7 , 8 As shown,

[0058] The filter press mechanism includes two elastic movable components symmetrically arranged on the fixed plate 300, and the bottoms of the two elastic movable components are respectively connected to the filter press wheel 304 and the scraper plate 305. The filter press wheel 304 and the scraper plate 305 are both located on the top of the rotating filter plate 400, and the two sides of the scraper plate 305 are respectively in contact with the inner stop structure and the outer stop structure.

[0059] When filtering edible oil, the oil is conveyed into the oil filter box 100 through two oil inlet pipes 101 by an external conveying device or manually, and the oil is filtered through the oil filter holes 401 on the left and right sides of the rotating filter plate 400, so that the filter residue remains on the top of the rotating filter plate 400, and the filtered oil enters the filter bag 104 through the oil collecting hopper 102 and the oil outlet trough 103, and is filtered twice by the filter bag 104, so that the edible oil undergoes two-stage filtering, thereby improving the filtering effect and oil quality.

[0060] The rotating filter plate 400 can be rotated at a slower speed through the driving action of the rotating component, so that the position of the rotating filter plate 400 is changed relative to the oil inlet pipe 101, avoiding the situation that the filtering position is fixed and too much filter residue is retained at the same position, thereby reducing the blockage problem and improving the filtering efficiency; as the rotating filter plate 400 rotates, the filter residue passes through the filter pressing wheel 304 on the corresponding side respectively, and the filter pressing wheel 304 is pressed tightly against the top of the rotating filter plate 400 through the action of the elastic moving component, and the filter residue passing through is fully squeezed and filtered, so that the oil in the filter residue can be squeezed out and enters the subsequent filter bag 104 for filtering treatment, thereby reducing oil waste, etc.

[0061] The filter residue after extrusion moves to the scraper plate 305. Through the cooperation of the scraper plate 305 with the inner and outer retaining structures, the filter residue of the rotating filter plate 400 is scraped and accumulated on the scraper plate 305. When the filtering work is completed, the inner and outer retaining structures move up, and the filter wheel 304 and the scraper plate 305 move up under the action of the elastic moving component, so that enough space is left on the top of the rotating filter plate 400, and then the transmission components on both sides drive the first push rod 703 and the second push rod 704 to move outward through the driving component, so that the two push plates 708 push the filter residue to fall into the discharge trough 106 on the corresponding side for discharge, thereby completing the cleaning of the filter residue on the rotating filter plate 400.

[0062] After the filter bag 104 performs secondary filtration on the oil, more fine filter residues are gradually accumulated inside. After the filtration is completed, the extrusion assembly is started to squeeze the middle filter bag 104 from top to bottom through the extrusion assemblies on both sides, so that the oil in the filter residue can be squeezed out, reducing oil waste, etc. When the filter bag 104 needs to be cleaned, the oil filter box 100 can be removed from the top of the collection box 200, and the filter bag 104 at the bottom can be replaced and cleaned and other maintenance operations can be performed.

The connecting rod 404 is fixed to the side wall of the oil filter box 100, and the position of the fixed plate 300 is staggered with the position of the discharge chute 106. The rotating filter plate 400 is limited and supported by the annular seat 403 and the rotating seat 402, so that the rotating filter plate 400 can rotate stably, and the rotating shaft 405 is driven by the motor to drive the rotating filter plate 400 to rotate, so as to switch the oil inlet position of the annular filter area, avoid filtering at the same position for a long time, and enable the filtered residue to be transferred to the filter wheel 304 and the scraper plate 305.

[0065] When it is necessary to move the push plates 708 on both sides outward, the two first bevel gears 705 drive the worm gears 700 on both sides to rotate simultaneously through the drive of the motor and the transmission of the second bevel gear 707 and the bevel gear ring 706, and then the two push plates 708 move outward at the same time through the transmission components on both sides, so as to push the filter residue on the rotating filter plate 400 to be discharged.

[0066] Among them, Figure 2As shown, the transmission assembly includes a transmission wheel 701 symmetrically meshed on both sides of the worm 700, and a transmission gear 702 is meshed on the other side of the transmission wheel 701, and the transmission gear 702 and the transmission wheel 701 are both rotatably connected to the bottom of the fixed plate 300, and the inner sides of the first push rod 703 and the second push rod 704 are provided with tooth grooves, and a plurality of teeth are evenly arranged in the tooth grooves along the length direction, and meshed with the transmission gear 702 on the corresponding side through the teeth.

[0067] When the worm 700 of the driving assembly rotates, the transmission wheels 701 on both sides rotate simultaneously and in opposite directions, and through the transmission of the transmission gear 702, the two first push rods 703 drive the push plate 708 at the rear position to move backward, and the two second push rods 704 drive the push plate 708 at the front position to move forward, wherein the transmission assembly at the second push rods 704 can adjust the transmission ratio of the worm 700, the transmission wheel 701 and the transmission gear 702 so that the push plates 708 on the front and rear sides have the same moving speed and opposite moving directions.
