Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil pressing equipment, and particularly relates to a fatty acid capturing device for oil pressing. BACKGROUND

[0002] In the oil pressing and oil refining process, free fatty acids contained in crude oil need to be removed by chemical methods (such as alkali refining method). In this process, free fatty acids react with lye to form soapstock. As the main carrier of fatty acids, soapstock needs to be completely separated from oil to ensure the quality of oil and fat. The existing fatty acid capturing device generally has the following problems:

[0003] 1. In the single barrel processing mode, the reaction of crude oil and lye is not sufficient, and free fatty acids that have not been reacted locally are easily left, resulting in low fatty acid capturing efficiency;

[0004] 2. The soapstock generated in the reaction is not only intercepted by the filter screen, but also adheres to the inner wall of the barrel in large quantities. The traditional cleaning method needs to manually disassemble the barrel or insert a tool to scrape it off, which is complicated and incomplete. The residual soapstock will contaminate the oil and fat in the subsequent processing, affecting the product quality;

[0005] 3. The soapstock collection and transportation process has low automation degree and needs manual intervention, which increases the labor intensity and easily causes soapstock to scatter and waste.

[0006] In view of the above problems, the present application designs a fatty acid capturing device with the functions of double-barrel alternating processing, automatic scraping of soapstock on the inner wall and efficient transportation of soapstock to solve the technical problems of the prior art.

[0060] Material barrel 2 working state switching

[0061] With the rotation of the rotating disc 104, the two groups of material barrels 2 have three working states to meet different process requirements.

[0062] State one: the first material barrel 201 and the second material barrel 202 are in the same horizontal plane, and at this time, the two groups of second winding mechanisms 302 are respectively located above the two groups of material barrels 2, and the oil liquid in the material barrels 2 can be injected and stirred.

[0063] State two: the first material barrel 201 is located above the second material barrel 202, and at this time, the first winding mechanism 301 is located above the first material barrel 201, and the oil pouring, filter screen 5 lifting and inner wall soapstock scraping operations from the first material barrel 201 to the second material barrel 202 can be performed.

[0064] State three: the second material barrel 202 is located above the first material barrel 201, and at this time, the first winding mechanism 301 is located above the second material barrel 202, and the oil pouring, filter screen 5 lifting and inner wall soapstock scraping operations from the second material barrel 202 to the first material barrel 201 can be performed.

[0065] In the working process of the embodiment:

[0066] Step 1: initial state preparation

[0067] The rotating disc 104 drives the two groups of material barrels 2 to be in the same horizontal plane, i.e. state one, the first material barrel 201 is filled with crude oil to be treated, and the oil amount is 2 / 3 of the volume of the material barrel 2, and the second material barrel 202 is empty; the liquid injection and stirring mechanisms 4 of the two groups of second winding mechanisms 302 are both in the initial position above the top frame 101; and the filter screen 5 in the first material barrel 201 has been reset to the bottom of the inner cavity of the material barrel 2, and the shovel blade 501 is attached to the inner wall of the material barrel 2.

[0068] Step 2: Liquid injection and stirring reaction in the first tank 201

[0069] The second winding mechanism 302 above the first tank 201 is started, the drive motor 402 is reversed to lower the rope, and the liquid injection and stirring mechanism 4 is lowered into the first tank 201, and the blade 404 is immersed in the crude oil;

[0070] The external alkali pump body is started, the alkali is introduced into the liquid warehouse 403 through the conduit 406 and the rotary joint, and is uniformly sprayed into the crude oil from the liquid outlet hole 405 through the hollow structure of the blade 404; at the same time, the sealing motor 402 is started to drive the liquid warehouse 403 and the blade 404 to rotate at a speed of 50-80r / min, realizing "liquid injection and stirring at the same time", and the stirring time lasts for 10-15min;

[0071] After the liquid injection and stirring are completed, the second winding mechanism 302 drives the liquid injection and stirring mechanism 4 to rise and reset above the top frame 101, and the alkali pump body is closed; the mixed liquid in the first tank 201 is left to stand for 20-30min, so that the free fatty acid fully reacts with the alkali to generate soapstock, and the soapstock with a density greater than oil will gradually settle above the filter screen 5.

[0072] Step 3: Oil pouring in the first tank 201 and soapstock collection

[0073] The turntable 104 is driven to rotate, so that the first tank 201 is rotated to above the second tank 202, that is, state two, and at this time the first winding mechanism 301 is located directly above the first tank 201;

[0074] The control valve at the bottom of the first tank 201 is opened, and the oil liquid in the first tank 201 flows into the second tank 202 through the mesh of the filter screen 5 under the action of gravity, while the soapstock is intercepted inside the filter screen 5; at the same time, part of the soapstock will adhere to the inner wall of the first tank 201;

[0075] After the oil liquid completely flows into the second tank 202, the control valve of the first tank 201 is closed; the first winding mechanism 301 is started, the drive motor 402 is reversed to lower the rope, and the lifting hook 504 is lowered into the first tank 201 and is connected with the fixed ring 503 at the top of the filter screen 5;

[0076] The drive motor 402 of the first winding mechanism 301 is forward rotated, the rope is wound, and the lifting hook 504 is synchronously lifted with the filter screen 5; during the lifting process, the spade 501 around the filter screen 5 moves upward along the inner wall of the first tank 201, and the soapstock adhered to the inner wall is completely scraped off, and the scraped soapstock slides along the spade 501 and falls into the filter screen 5;

[0077] When the filter screen 5 rises below the top frame 101 and is separated from the first barrel 201, the first winding mechanism 301 moves along the moving rail 303 to the preset soap foot transfer area, and after reaching the position, the control hook 504 is separated from the fixed ring 503 or the filter screen 5 is turned over to pour the soap foot collected inside, including the scraped inner wall soap foot, into the soap foot collection box.

[0078] After the soap foot pouring is completed, the first winding mechanism 301 returns to the position above the first barrel 201 along the moving rail 303, and the filter screen 5 is lowered to the bottom of the inner cavity of the first barrel 201 for resetting. The hook 504 is separated from the fixed ring 503, and the soap foot cleaning of the first barrel 201 is completed.

[0079] Step 4: Second barrel 202 repeats reaction and oil pouring

[0080] The rotating disc 104 is driven to rotate, and the two groups of barrels 2 return to the same horizontal plane, i.e., state one.

[0081] The second winding mechanism 302 above the second barrel 202 is controlled to start, and the liquid injection and stirring mechanism 4 is lowered into the second barrel 202 to repeat the liquid injection, stirring and standing operation of step 2 to perform secondary reaction and acid removal on the oil liquid in the second barrel 202.

[0082] After the standing is completed, the rotating disc 104 is driven to rotate, and the second barrel 202 is rotated to above the first barrel 201, i.e., state three. The control valve of the second barrel 202 is opened, the oil liquid flows into the first barrel 201, and the soap foot is intercepted by the filter screen 5 in the second barrel 202. The soap foot attached to the inner wall is scraped and transferred by the first winding mechanism 301 driving the filter screen 5 in the second barrel 202 to rise. The operation process is consistent with step 3.

[0083] Step 5: Multiple processing and final oil collection

[0084] Steps 2-4 are repeated to perform 3-5 rounds of alternating reaction and soap foot cleaning on the oil liquid. The specific number of rounds is adjusted according to the initial acid value of the crude oil, and the oil liquid is not qualified until the acid value meets the standard.

[0085] After the last round of processing is completed, the qualified oil liquid is transferred to one of the barrels 2, such as the second barrel 202. The control valve of the second barrel 202 is opened to guide the oil liquid into the storage barrel 103 on the base 102. After the receiving is completed, the storage barrel 103 is moved to transfer the oil to the subsequent refining process. At the same time, the filter screens 5 in the two groups of barrels 2 are transferred by the first winding mechanism 301, cleaned of residual soap foot, and reset to complete a fatty acid collection operation.

[0086] Through the above process, the device can realize sufficient reaction of oil, complete collection and automatic transfer of soap foot, and effectively improve the collection efficiency of fatty acid and the quality of oil during oil pressing.
