Description

Technical Field

[0001] The utility model relates to the technical field of vegetable oil production, in particular to a water-replacing oil discharge device. Background Art

[0002] The water-replacement method is a traditional oil extraction method suitable for the extraction of most woody or herbal oils such as walnut oil, tea seed oil, olive oil, peanut oil, etc. The water-replacement method produces vegetable oil by utilizing the different affinities of non-oil components in oil to oil and water. The production process usually involves grinding the oil, stirring it and heating it, then adding a certain amount of hot water and continuing to stir it. During the stirring process, water will replace the oil in the oil, and finally, the replaced oil and oil residue will be separated to obtain vegetable oil.

[0003] The existing equipment has the following disadvantages: in the prior art, the steps of adding water, stirring, filtering and separation in the production process are mainly completed manually, which is not only time-consuming and labor-intensive, but also inefficient; and when separating the processed oil from the oil residue, it is inconvenient to control the opening amount of the oil discharge port, thereby affecting the separation efficiency of the oil residue and the oil body.

[0004] Therefore, the present application now proposes a water-replacing oil discharge device to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a water-based oil discharge device to solve the problem that the above-mentioned manual work is not only time-consuming and labor-intensive, but also inefficient; and when separating the processed oil from the oil residue, it is inconvenient to control the opening amount of the oil discharge port, thereby affecting the separation efficiency of the oil residue and the oil body.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water-replacing oil discharge device, comprising an oil extractor, a feed port arranged on one side of the upper part of the oil extractor, a crushing unit arranged at the lower part of the feed port for crushing the oil, a water pipe arranged inside the oil extractor and a nozzle arranged on the water pipe, and also comprising:

[0007] A stirring unit, arranged inside the oil extraction machine and below the nozzle, for fully stirring the raw materials inside the oil extraction machine;

[0008] The discharging unit is arranged at the bottom of the oil extractor and at a side away from the feed port, and is used for discharging the processed oil and oil residue.

[0009] Among them, the discharging unit includes a mounting plate arranged at the bottom of the oil extraction machine, a cylinder arranged on the mounting plate, a first baffle arranged at the power output end of the cylinder and a second baffle connected to the first baffle, the second baffle is arranged below the oil extraction machine, and the oil extraction machine is provided with a discharge port for discharging oil at the position corresponding to the first baffle and the second baffle.

[0010] Wherein, a sliding groove for placing the first baffle is provided at a position of the second baffle corresponding to the first baffle.

[0011] Wherein, a slide rail is arranged at the position of the oil extraction machine corresponding to the second baffle plate, and a slider is arranged at the position of the second baffle plate corresponding to the slide rail, and the slider is slidably arranged inside the slide rail.

[0012] Wherein, a connecting component for limiting the position of the second baffle is provided at the position of the oil extraction machine corresponding to the first baffle.

[0013] Among them, the connecting component includes a first rack arranged on the first baffle, a fixed shaft arranged on the oil extraction machine, a gear sleeved on the fixed shaft and threadedly connected to the first rack, and a second rack threadedly connected to the gear and arranged at the lower part of the oil extraction machine, and a block is provided at the position of the second baffle corresponding to the second rack to block the second rack.

[0014] Wherein, a limiting block is arranged on one side of the second rack close to the oil extraction machine, and a limiting groove for sliding of the limiting block is provided at a position of the oil extraction machine corresponding to the limiting block.

[0015] Among them, the stirring unit includes a motor arranged inside the oil extractor, a rotating shaft arranged at the power output end of the motor and arranged inside the oil extractor, a main gear arranged on the rotating shaft, a slave gear threadedly connected to the main gear, and a connecting shaft arranged inside the oil extractor, the slave gear is sleeved on the connecting shaft, and the connecting shaft and the rotating shaft are both provided with an auger for stirring the raw materials inside the oil extractor.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model adds the oil to be processed into the inside of the feed port, and then enters the inside of the oil extractor after being crushed by the crushing unit, and then heats the oil in the oil extractor through the heating device, so that the oil is heated more evenly. When the temperature condition is reached (the protein has reached an emulsified state), the PLC controls the water injection tank to add a correct dose of pure water of about 70 degrees Celsius, and controls the stirring unit to mix the oil in the oil extractor. After adding water, the emulsified protein in the oil quickly absorbs the water and releases the oil. The oil after absorbing the water has stronger viscosity and will gradually form a mass after being squeezed. After stirring for a certain period of time, the oil in the oil is fully released. At this time, the stirring tank is filled with agglomerated solid oil residues. The mixture of oil and wood oil has been separated in form, which is convenient for the subsequent separation of oil and oil residue. When the oil separation is completed, the cylinder is started to drive the first baffle to move to the side close to the mounting plate, so that the discharge port is slightly opened (the opening is much smaller than the size of the lumpy oil residue). Then, the PLC controls the stirring unit to reverse, and the lumpy oil residue is transported to the end away from the discharge port, and will not accumulate at the discharge port to affect the outflow of oil from the discharge port. After the oil has flowed out, the cylinder drives the first baffle to move to the side close to the mounting plate, so that the second baffle moves, and then the discharge port is fully opened. The PLC controls the stirring unit to run forward, pushing the lumpy solid oil residue to the discharge port for discharge. It has a high degree of automation, saves time and effort, and the process parameters are controllable, so that the oil yield is high and the oil quality is good. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-7 The utility model provides a technical solution: a water-replacing oil discharge device, comprising an oil extractor 1, a feed port 3 arranged on one side of the upper part of the oil extractor 1, a crushing unit 4 arranged at the lower part of the feed port 3 for crushing the oil, a water pipe 5 arranged inside the oil extractor 1 and a nozzle 6 arranged on the water pipe 5, and also comprising:

[0028] The stirring unit 2 is arranged inside the oil extraction machine 1 and below the nozzle 6, and is used to fully stir the raw materials inside the oil extraction machine 1;

[0029] The discharging unit 7 is arranged at the bottom of the oil extractor 1 and at a side away from the feed port 3, and is used to discharge the processed oil and oil residue.

[0030] It should be noted that, during operation, the oil to be processed is added to the inside of the feed port 3, and then enters the inside of the oil extractor 1 after being crushed by the crushing unit 4, and then the oil inside the oil extractor 1 is heated by the heating device to make the oil heating more uniform. When the temperature condition is reached (the protein has reached an emulsified state), the PLC controls the water injection tank to add the correct dose of pure water of about 70 degrees Celsius, and controls the stirring unit 2 to mix the oil inside the oil extractor 1. After adding water, the emulsified protein in the oil quickly absorbs water and releases oil. The oil has stronger viscosity after absorbing water, and will gradually form a mass after being squeezed. After stirring for a certain period of time, the oil in the oil is fully released. At this time, the stirring tank is filled with a mixture of solid oil residue and woody oil in a mass, and the two have been separated in shape, which is convenient for the subsequent separation of oil and oil residue.

[0031] In one embodiment, the discharging unit 7 includes a mounting plate 71 arranged at the bottom of the oil extraction machine 1, a cylinder 72 arranged on the mounting plate 71, a first baffle 73 arranged at the power output end of the cylinder 72, and a second baffle 74 connected to the first baffle 73. The second baffle 74 is arranged below the oil extraction machine 1, and a discharge port 8 for discharging oil is opened at the position of the first baffle 73 and the second baffle 74 of the oil extraction machine 1 corresponding to the first baffle 73 and the second baffle 74.

[0032] In this design, when the oil separation is completed, the cylinder 72 is started to drive the first baffle 73 to move to the side close to the mounting plate 71, so that the discharge port 8 is slightly opened (the opening is much smaller than the size of the lump oil residue), and then, the PLC controls the stirring unit 2 to reverse, and the lump oil residue is transported to the end away from the discharge port 8, and will not accumulate at the discharge port 8 to affect the outflow of the oil from the discharge port 8. After the oil has flowed out, the cylinder 72 drives the first baffle 73 to move to the side close to the mounting plate 71, so that the second baffle 74 moves, and then the discharge port 8 is fully opened, and the PLC controls the stirring unit 2 to run forward, pushing the lump solid oil residue to the discharge port 8 for discharge.

[0033] In one embodiment, a sliding groove 741 for placing the first baffle plate 73 is formed at a position of the second baffle plate 74 corresponding to the first baffle plate 73 .

[0034] With this design, the first baffle 73 is slidably disposed inside the second baffle 74, which can conveniently control the opening state of the discharge port 8, thereby facilitating the separation of the oil body and the oil residue.

[0035] In one embodiment, a slide rail 75 is provided at a position of the oil extraction machine 1 corresponding to the second baffle 74 , and a slider 742 is provided at a position of the second baffle 74 corresponding to the slide rail 75 . The slider 742 is slidably disposed inside the slide rail 75 .

[0036] With this design, the second baffle 74 can be adjustably arranged inside the slide rail 75, which can conveniently control the opening of the discharge port 8, realize automatic control of oil discharge and oil residue discharge, and thus improve the processing efficiency of the oil.

[0037] In one embodiment, a connecting component 76 for limiting the position of the second baffle 74 is provided at the position of the oil extraction machine 1 corresponding to the first baffle 73 .

[0038] With this design, the connecting component 76 can limit the second baffle 74, so that when the cylinder 72 controls the first baffle 73 to open, the second baffle 74 will not be opened, thereby controlling the opening size of the discharge port 8 and further controlling the discharge efficiency of the oil residue and the oil body.

[0039] In one embodiment, the connecting component 76 includes a first rack 761 arranged on the first baffle plate 73, a fixed shaft 763 arranged on the oil extraction machine 1, a gear 762 sleeved on the fixed shaft 763 and threadedly connected to the first rack 761, and a second rack 764 threadedly connected to the gear 762 and arranged at the lower part of the oil extraction machine 1. A stopper 743 is provided at the position of the second baffle plate 74 corresponding to the second rack 764 to block the second rack 764.

[0040] With this design, after the oil is discharged from the discharge port 8, the cylinder 72 drives the first baffle 73 to continue to move toward the side close to the mounting plate 71, and then makes the first rack 761 mesh with the gear 762, driving the gear 762 to rotate, and then driving the second rack 764 to move toward the side away from the stop block 743, thereby releasing the restriction of the second rack 764 on the stop block 743, and then the cylinder 72 can drive the second baffle 74 to slide inside the slide rail 75, so that the discharge port 8 can be fully opened, so as to facilitate the discharge of the oil residue inside the oil extractor 1.

[0041] In one embodiment, a limiting block 7641 is provided on one side of the second rack 764 close to the oil extraction machine 1 , and a limiting groove 11 for the limiting block 7641 to slide is provided at a position of the oil extraction machine 1 corresponding to the limiting block 7641 .

[0042] With this design, the limit block 7641 set at the lower end of the second rack 764 moves inside the limit groove 11, which can easily limit the moving position of the second rack 764 and make the second rack 764 move more smoothly.

[0043] In one embodiment, the stirring unit 2 includes a motor 21 arranged inside the oil extraction machine 1, a rotating shaft 22 arranged at the power output end of the motor 21 and arranged inside the oil extraction machine 1, a main gear 23 arranged on the rotating shaft 22, a slave gear 24 threadedly connected to the main gear 23, and a connecting shaft 26 arranged inside the oil extraction machine 1. The slave gear 24 is sleeved on the connecting shaft 26, and both the connecting shaft 26 and the rotating shaft 22 are provided with an auger 25 for stirring the raw materials inside the oil extraction machine 1.

[0044] With such a design, the motor 21 can control the rotation of the rotating shaft 22, so that the main gear 23 drives the slave gear 24 to rotate, and then the connecting shaft 26 rotates, so that the two augers 25 can rotate inside the oil extractor 1, so that the oil inside the oil extractor 1 can be fully mixed, and the degree of automation is high, time and labor are saved, and the process parameters are controllable, so that the oil yield is high and the oil quality is good.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying the importance of the relative description or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
