Description

Technical Field

[0001] This utility model relates to the field of soybean oil production technology, specifically to an auxiliary device for an extractor used in the production of soybean oil. Background Technology

[0002] Soybean oil is one of the most consumed edible oils in my country, and solvent extraction is currently the main industrial method for producing soybean oil. Solvent extraction offers advantages such as high oil yield, high production efficiency, and low residual oil content in the soybean meal, fully realizing the economic value of soybeans. In the solvent extraction process, the solvent extractor is the core equipment. Existing solvent extractors include: drag chain solvent extractors, rotary solvent extractors, and spray solvent extractors. Among these, the spray solvent extractor uses a pump to continuously spray solvent or mixed oil onto the feed layer in a counter-current manner through nozzles. The oilseeds complete the solvent extraction process under the continuous spraying action of the solvent or mixed oil. After the solvent comes into contact with the oil in the oilseeds, the oil is extracted from the oilseeds through dissolution and diffusion, forming a mixed oil. The mixed oil is separated from the residue by filtration or sedimentation, and then undergoes subsequent processing, such as evaporation and stripping, to recover the solvent and obtain the finished oil.

[0003] However, during the transport of oil in a spray-type extractor, the oil has poor fluidity, and the sprayed liquid cannot penetrate deep into the oil, resulting in spray dead zones. Utility Model Content

[0004] This invention addresses the technical problem that, during the transport of oil in a spray-type extractor, the oil has poor fluidity, preventing the sprayed liquid from penetrating deep into the oil and causing spray dead zones. Therefore, it provides an auxiliary device for extractors used in soybean oil production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for an extractor used in the production of soybean oil, comprising: an extraction chamber, wherein multiple sets of conveyors operating in the same direction are arranged in a stepped manner inside the extraction chamber, each conveyor consisting of a conveying roller and a perforated belt, the perforation diameter of which is smaller than the minimum particle size of the raw material, the shaft end of the conveying roller being rotatably connected to the side wall of the extraction chamber, an inlet being provided on the top wall of the extraction chamber at the upper part of the conveying start end of the uppermost conveyor, a spraying device being provided on the upper part of each conveyor, the spraying device being connected to the extraction chamber, a transfer fan blade being provided on the outer surface of the perforated belt at the conveying end of each conveyor, the shaft end of the transfer fan blade being rotatably connected to the inner wall of the extraction chamber, the maximum rotation path of the transfer fan blade being tangent to the outer surface of the conveying end of the perforated belt, the raw material being conveyed above the transfer fan blade into the next conveyor, a discharge port being provided on the bottom wall of the extraction chamber below the lowermost transfer fan blade, a vertical plate being connected to the bottom wall of the extraction chamber at the discharge port, and a liquid drain being connected to the bottom of the extraction chamber.

[0006] Preferably, one side of the transfer fan blade is tangent to the outer surface of the perforated belt, and the other side of the transfer fan blade is provided with a flow restrictor. The inner surface of the flow restrictor coincides with the maximum rotation path of the transfer fan blade, and the lower end of the flow restrictor extends to the lower part of the transfer fan blade.

[0007] Preferably, the spraying device includes an inlet pipe, to which multiple spray pipes are connected. The spray pipes are horizontally positioned above the perforated belt, and each spray pipe is connected to multiple nozzles. The flow rate of the inlet pipe of each conveyor gradually decreases along the conveying direction.

[0008] Preferably, the perforated belt includes a belt body and a filter cloth, the belt body having elongated holes, and the filter cloth covering the outer surface of the belt body.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The oil on the previous conveyor is transferred to the next conveyor by the transfer fan blades. During the transfer process, the oil is turned over and flows and falls. The dead corners that were originally unable to be sprayed are turned over and sprayed, and the grease is soaked out. After multiple stages of conveying, the leaching effect is very good.

[0011] Along the conveying direction, the flow rate of the inlet pipe of each conveyor gradually decreases. As the oil content in the material decreases, continuing to maintain a high flow rate of solvent spraying may result in an excessively low concentration of mixed oil, thus avoiding increasing the cost and difficulty of subsequent solvent recovery and mixed oil treatment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] The following is in conjunction with the appendix Figure 1-3 This embodiment describes an auxiliary device for a soybean oil extractor, comprising: an extraction chamber 1, in which multiple sets of co-rotating conveyors are arranged in a stepped manner. Each conveyor consists of a conveying roller 2 and a perforated belt 3. The perforated belt 3 has a diameter smaller than the minimum particle size of the raw material. The shaft ends of the conveying roller 2 are rotatably connected to the side wall of the extraction chamber 1. The top wall of the extraction chamber 1 at the upper part of the uppermost conveyor has a feed inlet 4. Each conveyor has a spray device 5 at its upper part, which is connected to the extraction chamber 1. The outer surface of the perforated belt 3 at the end of each conveyor has a transfer fan blade 6. The shaft end of the transfer fan blade 6 is rotatably connected to the inner wall of the extraction chamber 1. The maximum rotation path of the transfer fan blade 6 is tangent to the outer surface of the end of the perforated belt 3. The raw material is conveyed above the transfer fan blade 6 to the next conveyor. The bottom wall of the extraction chamber 1 below the lowermost transfer fan blade 6 has a discharge port 7. The bottom wall of the extraction chamber 1 at the discharge port 7 is connected to a vertical plate 8. The bottom of the extraction chamber 1 is connected to a liquid drain port 9.

[0020] The oil is injected into the leaching chamber 1 and falls onto the perforated belt 3 of the uppermost conveyor. The upper spraying device 5 sprays the leaching solvent, and the solvent and grease flow out through the perforated belt 3 and the drain port 9. Power is input through the shaft end of the conveyor roller 2 to drive the perforated belt 3 to rotate. The perforated belt 3 transports the oil to the transfer fan blade 6. Power is input through the shaft end of the transfer fan blade 6 to drive the transfer fan blade 6 to rotate and enter the next conveyor through the upper conveyor. During the transfer process, the oil is turned over and flows and falls. The dead corners that could not be sprayed before are turned over and sprayed to leach out the grease. After multiple stages of conveying, the leaching effect is very good.

[0021] One side of the transfer fan blade 6 is tangent to the outer surface of the perforated belt 3, and the other side of the transfer fan blade 6 is provided with a flow restrictor 10. The inner surface of the flow restrictor 10 coincides with the maximum rotation path of the transfer fan blade 6, and the lower end of the flow restrictor 10 extends to the lower part of the transfer fan blade 6.

[0022] The transfer fan blade 6 works in conjunction with the flow restrictor 10 to ensure that the oil falling rate and flow rate are uniform, preventing the oil from falling in clumps and causing uneven thickness, which would affect the leaching effect.

[0023] The spraying device 5 includes an inlet pipe 51, and multiple spray pipes 52 are connected to the inlet pipe 51. The spray pipes 52 are horizontally arranged above the perforated belt 3. Multiple nozzles 53 are connected to each spray pipe 52. The flow rate of the inlet pipe 51 of each conveyor gradually decreases along the conveying direction.

[0024] The liquid pump pumps the solvent into the inlet pipe 51, and then sprays it downwards through the spray pipe 52 and the nozzle 53. As the oil content in the material decreases, continuing to maintain a high flow rate of solvent spraying may cause the mixed oil concentration to be too low. Therefore, the flow rate of the inlet pipe 51 of each conveyor is gradually reduced along the conveying direction to avoid increasing the cost and difficulty of subsequent solvent recovery and mixed oil treatment.

[0025] The perforated belt 3 includes a belt body 31 and a filter cloth 32. The belt body 31 is provided with elongated holes, and the filter cloth 32 covers the outer surface of the belt body 31.

[0026] The belt body 31 is used in conjunction with the filter cloth 32 to avoid the disadvantages of the small holes on the belt body 31 being easy to clog and difficult to clean.
