Description

Technical Field

[0001] The present invention relates to the technical field of fruit juice production, and particularly relates to a multi-stage filtration and purification device for fruit juice processing. Background Art

[0002] Fruit juice production belongs to a subdivision of the food processing industry, also known as the fruit juice processing industry. Fruit juice production is a complex technological process, mainly including: raw material preparation, juicing, pulping, clarification and filtration, blending, homogenization treatment, etc. When producing fruit juice, in order to remove impurities, extend the shelf life, improve the taste and ensure food safety, etc., it is often necessary to filter and purify the fruit juice.

[0003] In the prior art, a filter screen is often used during the filtration and purification process of fruit juice. Thus, during the fruit juice production process, the impurity particle sizes inside different types of fruit juice are also different. At this time, the aperture of the filter screen often needs to be adjusted according to the filtration type of the fruit juice. The existing aperture adjustment means usually adjusts the diameter of the angled holes between two groups of mesh holes by changing the staggered angle between them. Then, one of the filter screens needs to rotate. When the fruit juice is added into the equipment, the impact force generated by the falling of the fruit juice itself will directly act on the filter screen. At this time, the position of the impacted filter screen will change rotationally compared to before, which will cause the diameter of the angled holes between the two groups of filters to change, resulting in its inability to meet the filtration grade requirements and affecting the filtration and purification effect of the fruit juice. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a multi-stage filtration and purification device for fruit juice processing to solve the problems raised in the above background art.

One end of the first connecting column is fixedly installed with the limiting plate. A number of semi-hole rods are fixedly installed on the inner circumferential wall of the positioning ring. Each semi-hole rod, one semi-hole plate and one limiting plate form a group; A number of adjusting components are arranged on the bottom surface of the positioning ring and are used to adjust the use spacing between the semi-hole rods and the semi-hole plates; A number of first installation sleeves are fixedly sleeved on the outer circumferential wall of the rotating shaft.

[0006] By adopting the above technical solution, during use, when the staff adds the juice to be filtered and purified into the tank body, the holes formed between the multiple semi-hole rods and multiple semi-hole plates in the tank body will filter the impurities contained in the juice. At this time, since the hole diameters of the holes formed by the multi-layer semi-hole rods and semi-hole plates gradually decrease from top to bottom, the impurities in the juice can be subjected to multi-stage filtration treatment. When the staff needs to adjust the holes between the multiple semi-hole rods and multiple semi-hole plates according to the type of juice, the staff uses the adjusting component, and then the adjusting component will push the semi-hole plate to rotate slightly. Then the hole diameters of the multiple holes between the semi-hole rod and the semi-hole plate will be widened. At this time, the hole diameter between the semi-hole rod and the semi-hole plate is increased. During this process, as the semi-hole plate rotates, it will drive the first connecting column to squeeze the fourth spring, so as to adjust the use hole diameters between the multiple semi-hole rods and multiple semi-hole plates in the multiple positioning rings inside the tank body, so as to facilitate the multi-stage filtration and purification treatment of different types of juice.

[0007] Preferably, a plurality of the adjusting components include: a plurality of adjusting blocks, the plurality of adjusting blocks are respectively fixedly installed on the bottom surfaces of the plurality of semi-hole plates, a plurality of first mounting seats are fixedly installed on the bottom surface of the positioning ring, the position of each first mounting seat corresponds to the position of each adjusting block, a second connecting column is movably sleeved inside the first mounting seat, a blocking ring is fixedly sleeved on the outer circumferential wall surface of the second connecting column, a rubber sealing ring is fixedly sleeved on the outer circumferential wall surface of the blocking ring, a push head is fixedly installed at one end of the second connecting column, a tapping head is fixedly sleeved on the inner circumferential wall surface of the first mounting seat, a plurality of series pipes are arranged on the bottom surfaces of the plurality of positioning rings, the outer circumferential wall surface of the series pipe is fixedly sleeved with the inner circumferential wall surface of the tapping head, and a plurality of pipe joints are arranged on the outer circumferential wall surface of the tank body, and the pipe joints are fixedly sleeved with the inner circumferential wall surface of the series pipe.

Then, when the staff needs to adjust the use distance between the plurality of semi-hole rods and the plurality of semi-hole plates, the staff fills the inside of the series pipe with gas through the air pump. Then, the gas inside the series pipe will enter the inside of the first mounting seat through the tapping head. At this time, since high-pressure gas is continuously added to the inside of the first mounting seat, the blocking ring will drive the second connecting column and the push head to move forward. Then, the inclined surface on the side of the push head will push the inclined surface at the bottom of the adjusting block to make it move, so as to change the use distance between the plurality of semi-hole rods and the plurality of semi-hole plates, thus facilitating the adjustment of the use distance between the plurality of semi-hole rods and the semi-hole plates.

At this time, the multiple rollers inside the positioning frame will roll along the inclined surface at the bottom of the receiving plate, and at the same time, lift the receiving plate together with the cleaning brush upward. Then, the bristles on the surface of the cleaning brush will enter the holes between the multiple semi-hole rods and the semi-hole plates and push out the blocked impurities inside, so as to facilitate the cleaning of the holes between the multiple semi-hole rods and the semi-hole plates and prevent blockage.

[0023] In summary, the present invention mainly has the following beneficial effects: The holes formed between multiple half-hole rods and multiple half-hole plates will filter the impurities contained in the juice. At this time, since the hole diameters of the holes formed by the multi-layer half-hole rods and half-hole plates gradually decrease from top to bottom, the impurities in the juice can be subjected to multi-stage filtration treatment.
