technical field

The invention belongs to the field of oil extraction from mangosteen shells, in particular to a pressing device and a separation method for extracting volatile oil from mangosteen shells.

Background technique

Mangosteen shell can clear away heat and detoxify, dampness and relieve diarrhea. Mangosteen shell contains a lot of tannic acid, which can help treat acne and skin wounds, so it is of great value. Mangosteen shell is usually passed through Utilize by squeezing oil to extract useful substances.

Existing pressing devices usually use pressurized filtration to extract oil from mangosteen shells. During the oil extraction process, the mangosteen shells usually come into contact with the filter screen, and the mangosteen shells will exert greater pressure on the filter screen, while the inside of the filter screen is a net The pore structure leads to low overall strength of the filter screen, and it is easy to deform under pressure, which makes the filter screen compressive capacity low, so the filter screen is easily deformed or even damaged during the pressing process, and the mangosteen shell is in contact with the filter screen under high pressure, which is easy to block the screen Holes, this will not only cause the problem of filter blockage, but also reduce the filtration efficiency of the filter screen.

Therefore, the existing pressing device has the problem of low pressure resistance of the filter screen and the problem that the filter screen is easily blocked. Therefore, we propose a pressing device and a separation method for extracting volatile oil from mangosteen shells.

In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:

The present invention is a squeezing device for extracting volatile oil from mangosteen shells, comprising a base, a positioning tube fixedly installed above the base, a filter press tube fixedly set at one end of the positioning tube, a screw rod movably set inside the positioning tube and the filter press tube, And the first motor for driving the screw rod to rotate, the inner diameter of the filter press tube is smaller than the inner diameter of the positioning tube, and the ring side of the filter press tube is provided with a plurality of filter holes, between the positioning tube and the filter press tube Two first filter assemblies with anti-pressure and anti-blocking capabilities are fixedly arranged, and the two first filter assemblies are arranged symmetrically between the positioning pipe and the filter press pipe, and the second filter assembly is arranged on the filter press pipe , the second filter assembly is used to reinforce the filter press tube and to avoid clogging of the filter holes;

The inside of the first filter assembly is provided with a rolling groove and a liquid guide chamber, and the roll groove and the liquid guide chamber are connected. The first filter assembly includes an inner half pipe fixedly installed between the positioning pipe and the filter press pipe and The outer half pipe, the balls that are movable inside the rolling groove, and the support block fixedly arranged inside the liquid guiding chamber, the rolling groove is set inside the inner half pipe and the outer half pipe, and the inner half pipe and the outer half pipe Evenly spaced on the top, the balls and the rolling grooves are in clearance fit, the liquid guide chamber is set on the adjacent side of the inner half pipe and the outer half pipe, the liquid guide chamber is used for the collection of squeezed oil, the support The blocks are evenly spaced inside the liquid guide chamber, the ball and the ring side are provided with an oil guide groove for oil discharge, the inner half pipe, support block and outer half pipe are used to improve the overall strength of the first filter assembly, the roller Grooves, balls and oil guide grooves cooperate to filter, and balls and oil guide grooves are used to prevent clogging of rolling grooves.

The wall thickness of the inner half pipe and the outer half pipe is between 5-10mm, and the pressure resistance is strong, and it will not deform during the pressing process of the mangosteen shell. The inner half pipe and the outer half pipe pass through the gap between the ball and the rolling groove The gap is used for filtering, and the oil is brought out through the oil guide groove, so as to play the role of filtering. This structure is convenient to improve the overall strength of the first filter assembly, making the compression resistance higher, and solving the deformation that occurs when the traditional filter screen is pressed. The problem.

The gap between the ball and the rolling groove is between 0.2-0.8mm, and the depth of the oil guiding groove is between 0.5-1mm, and the inner wall section of the oil guiding groove is arc-shaped, which makes it difficult for the mangosteen shell to pass through. The internal rolling can squeeze out the impurities attached to the rolling groove by rolling, so that the rolling groove will not be blocked. At the same time, when the mangosteen shell passes through the ball, there will be a gap between the mangosteen shell and the ball, which is convenient for saving and pressing.

At the same time, the spiral liquid guide block is attached to the ring side of the filter press tube. After the mangosteen shell inside the filter press tube generates a large pressure, the spiral liquid guide block will produce reverse pressure on the filter press tube, and make the pressure inside and outside the filter press tube tend to be Consistent, so that the filter press tube will not be deformed due to excessive internal pressure. The squeezed oil can reduce the friction between the filter press tube and the spiral liquid guide block, and facilitate the rotation of the spiral liquid guide block on the filter press tube. Moreover, the helical liquid guide block will scrape off the impurities attached to the filter holes in the filter press tube during the rotation process, so as to avoid blockage of the filter holes.

A pressing device for extracting volatile oil from mangosteen shells according to claim 6, characterized in that: a liquid contact box (19) is fixedly installed under the side of the booster pipe (18), and the liquid contact box (19) It is located directly below the first filter assembly and the second filter assembly, and the liquid contact box (19) supports the booster pipe (18) at the same time, and a valve (20) is fixedly installed on one side of the liquid contact box (19) .
A pressing device for extracting volatile oil from mangosteen shells according to claim 7, characterized in that: a feeding bin (21) is fixedly installed at the feeding end of the positioning pipe (2).
A pressing device for extracting volatile oil from mangosteen shells according to claim 8, characterized in that: the oil guide grooves (13) are evenly distributed on the ring side of the ball (11).
The separation method of a pressing device for extracting volatile oil from mangosteen shells according to claim 9, comprising the following steps:

S1. Add the mangosteen shells to be squeezed from the feed bin (21), and the first motor (5) transports the mangosteen shells inside the positioning tube (2) through the screw rod (4). , the pressure between the mangosteen shells inside the positioning pipe (2) is greater, and the pressure between the mangosteen shells at the first filter assembly reaches the degree of extruding oil;

S2. Inside the inner half pipe (7), during the process of conveying the mangosteen shells by the screw rod (4), the friction between the mangosteen shells and the balls (11) drives the balls (11) to roll inside the rolling groove (9), and the balls ( 11) During the rolling process, the oil squeezed from the mangosteen shell enters the oil guide groove (13), and enters the inside of the rolling groove (9) through the rotation of the ball (11), and the squeezed oil enters the liquid guide chamber (10) continuously Converge and finally discharge from the outer side of the outer half-pipe (8);

S3, the mangosteen shells squeezed once continue to be transported to the second filter assembly, the mangosteen shells are subjected to greater pressure, and the remaining oil is squeezed out, and the squeezed oil is discharged through the filter hole (6), and the spiral guide block (14) and The guide tube (15) guides the squeezed oil to the side close to the first filter assembly through rotation, and flows out at the opening of the guide tube (15), and the squeezed oil is collected by the liquid receiving tank (19);

S4, the mangosteen shells that have been squeezed out of oil finally form oil cakes, and are discharged from the discharge end of the filter press pipe (3).
