Description

Technical Field

[0001] This utility model relates to the technical field of flaxseed pressing equipment, specifically to a flaxseed oil pressing device. Background Technology

[0002] Flaxseed's main components are fat, protein, and dietary fiber. Other components include minerals, alpha-linolenic acid, lignans, flaxseed gum, and vitamins. Scientific research shows that flaxseed contains toxic substances or anti-nutritional factors such as cyanogenic glycosides, anti-VB6 factors, and phytic acid. Cyanogenic glycosides, also known as cyanogenic glycosides or cyanoglycosides, can produce cyanide under the action of hydrolytic enzymes (β-glucosidase). Raw flaxseed contains varying amounts of cyanogenic glycosides, which differ significantly depending on the variety, origin, and environment.

[0003] Related technologies use screw oil presses to press flaxseeds for oil extraction. Screw oil presses mainly consist of a feed hopper, a pressing cage, a screw shaft, a cake discharge adjustment device, and a temperature control device.

[0004] Existing screw oil presses work by feeding flaxseeds into a hopper, which then enters the screw shaft. The screw shaft consists of multiple screws (with gradually decreasing pitch and gradually increasing diameter), which rotate and push the material towards the cake outlet while applying gradually increasing pressure to extract oil. The oil cake is then discharged from the pressing device through a cake adjustment device. However, most screw oil presses currently lack a cake recovery device and instead rely on a screw conveyor at the bottom of the machine to discharge the oil cake. The oil cake often scatters on the ground, making collection cumbersome, and broken pieces are also difficult to collect. To address these issues, a flaxseed oil pressing device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a flaxseed oil pressing device. The present invention uses a bolt conveyor to transport the oil cake to the discharge pipe, and then uses an elbow and a hopper to allow the oil cake to enter the primary sliding pipe and the secondary sliding pipe. The oil cake in the secondary sliding pipe falls into the collection trough in the collection box. After a certain amount is collected, the oil cake can be easily transferred and packaged by using a handle to remove the collection trough. This facilitates the collection of oil cake.

[0006] To solve the above-mentioned technical problems, this utility model provides a flaxseed oil pressing device, including a multi-stage screw press installed at the top of a screw oil press, a screw conveyor installed at the bottom of the screw oil press, multiple support columns installed at the bottom of the outer casing of the screw conveyor, a sealing plate detachably installed at the discharge port of the screw conveyor, a discharge pipe connected to the end of the sealing plate away from the screw oil press, a primary sliding pipe installed at an incline at the bottom of the discharge pipe, a secondary sliding pipe installed at an incline at the end of the primary sliding pipe closer to the screw oil press, and a collection component installed at the discharge end of the secondary sliding pipe.

[0007] The collection assembly includes a collection box connected to the secondary slide tube. The collection box is used to hold the collection trough and also to collect the oil cake falling from the secondary slide tube. The collection box has a hollow design, and one side of the collection box is provided with a movable groove. The movable groove facilitates the up and down movement of the handle and also supports the handle.

[0008] A collection trough is placed at the bottom of the collection box to collect oil cakes, which can then be transferred within the collection box. The collection trough fits tightly against the inner wall of the collection box. A connecting block is provided on the side of the collection trough that fits against the movable trough. The connecting block is used to connect the collection trough to a handle. The handle is provided on the connecting block, which makes it easy for personnel to move the collection trough out of the collection box, thus facilitating the packaging of the oil cakes. The handle slides and adapts to the movable trough.

[0009] The discharge end of the discharge pipe is equipped with an elbow, which is used to connect the discharge pipe to the hopper. The hopper is located at the bottom of the elbow and is shaped like a frustum. The hopper and the elbow can be welded together. The discharge end of the hopper is connected to the primary sliding pipe.

[0010] Multiple separating rods are installed in the middle of the discharge pipe. The separating rods are used to install blades. Each separating rod has a blade on the side facing the screw conveyor. The blades are used to separate large pieces of oil cake so that the oil cake can pass through the primary and secondary sliding pipes into the collection tank. Each separating rod has a positioning block at both the upper and lower ends. The positioning block is used to connect the separating rod to the inner wall of the discharge pipe, thereby supporting the blade. The positioning block is welded to the inner wall of the discharge pipe.

[0011] The multi-stage screw press is equipped with a motor at its output end, which drives the multi-stage screw press to rotate. The motor surface is covered with a housing, which protects the motor from dust and collisions with foreign objects. A heat dissipation device is installed at the rear of the housing to dissipate heat from the motor, thereby stabilizing the working efficiency of the multi-stage screw press.

[0012] The heat dissipation device includes a fan frame fixed to the rear wall of the machine casing. The fan frame is used to fix the suction cooling fan. The suction cooling fan is installed inside the fan frame. The suction cooling fan is used to exhaust the heat inside the machine casing from the screw oil press. A heat dissipation plate is installed at the air outlet of the suction cooling fan. The heat dissipation plate is used to improve the heat dissipation efficiency of the blower cooling fan. The heat dissipation plate is connected to the output end of the suction cooling fan. A dustproof plate is detachably installed at the rear of the fan frame. The dustproof plate is used to prevent the heat dissipation device from being affected by dust.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. The oil cake is conveyed to the discharge pipe by the bolt conveyor, and then enters the primary and secondary sliding pipes through the elbow and the discharge hopper. The oil cake in the secondary sliding pipe falls into the collection trough in the collection box. After a certain amount is collected, the oil cake can be easily transferred and packaged by using the handle to remove the collection trough. This makes it convenient to collect the oil cake.

[0015] 2. The blade is used to separate large pieces of oil cake, so that the oil cake can pass through the primary and secondary sliding pipes into the collection tank. The positioning block is used to connect the separating rod to the inner wall of the discharge pipe, thereby supporting the blade.

[0016] 3. The heat dissipation device is used to cool the motor, thereby stabilizing the working efficiency of the multi-stage screw press. Attached Figure Description

The screw press 101 has a larger helix angle in the feeding section and a smaller helix angle in the extrusion section, forming a conversion from screw propulsion force to radial extrusion force. A screw conveyor 102 is installed at the bottom of the screw oil press 100. The screw conveyor 102 consists of a cylindrical screw channel 105, a screw feeding shaft, screw blades, and a motor 103. A support casing is installed outside the screw channel 105. The screw conveyor 102 is used to convey the oil cake falling from the multi-stage screw press 101 out of the screw oil press. Multiple support columns 200 are installed at the bottom of the outer casing of the screw conveyor 102. The support columns 200 are welded to the bottom of the outer casing of the screw conveyor 102. The discharge port of the screw conveyor 102 is detachably provided.
