An apparatus and method for detecting the oil content of oily sludge.

Abstract

This invention discloses an oil content detection device and method for oily sludge, comprising a feeding box, a connecting box, and a processing box. The feeding box has an opening near the front of its bottom, and a reset plate is fitted into the inner cavity of the opening. Several filter papers are arranged on the top of the reset plate, and reset springs are fixedly connected to the bottom of the reset plate near its four corners. This invention utilizes the cooperation between components such as a feeding motor, crossbar, rectangular chain, side plate, rectangular plate, center plate, translation plate, rubber wheel, linkage block, lower trigger, and upper trigger. When the feeding motor starts, the rectangular chain drives the rubber wheel to move in a rectangular motion, causing the filter paper to move to the left. Because the left side of the filter paper is in contact with the anti-slip layer on the right side of the processing box, the middle part of the filter paper bulges. When the linkage block moves to the left, it also contacts the lower trigger, causing the reciprocating rod to insert into the bulging part of the filter paper and turn the filter paper into a vertical position for easier subsequent processing.

Description

Technical Field

[0001] This invention relates to the field of oily sludge treatment technology, specifically to an oil content detection device and method for oily sludge. Background Technology

[0002] Oily sludge refers to soil mixed with heavy oils such as crude oil, refined oil, and residual oil. This type of sludge does not exist naturally, but rather is a complex mixture formed when crude oil or refined oil leaks into the environment during oilfield extraction, refining, transportation, use, and storage due to improper operation, equipment aging, damage, or corrosion, and then mixes with soil, water, and other media.

[0003] When cleaning the interior of oil tankers, oily sludge is generated. Reducing the water content is a crucial pretreatment step before the sludge undergoes high-temperature decomposition. Mechanical dewatering and chemical conditioning are two commonly used methods. Mechanical dewatering is suitable for sludge with simple composition and low oil content, with the advantage of no chemical pollution. Chemical conditioning, on the other hand, targets high-oil-content, difficult-to-treat sludge, improving efficiency by enhancing dewatering properties. In practice, the two methods are often used in combination to achieve the best balance between dewatering effect and cost.

[0004] However, when high-oil sludge is directly mechanically dewatered, the grease will clog the filter cloth / screen, causing a sharp drop in dewatering efficiency or even equipment failure. When low-oil sludge is treated with chemicals, not only will there be excessive amounts of chemicals, but additional pollutants will also be introduced. Therefore, oil sludge needs to be tested for oil content before high-temperature treatment. Summary of the Invention

[0012] A method for detecting the oil content of oily sludge using an oil-containing sludge detection device includes the following steps:

[0014] S2: When it is necessary to test the oil content of oily sludge, start the feeding motor. When the feeding motor starts, it drives the rubber wheel to move in a concave shape. During the movement, it drives the filter paper to move to the left and starts the lower trigger.

[0015] S3: When the lower trigger starts, it drives the reciprocating cylinder to move upward and starts the upper trigger, thereby causing the reciprocating rod to move backward and limit the filter paper.

[0016] S4: When the filter paper is in a vertical position, the lifting cylinder fixes the vertical filter paper and starts the material pulling cylinder to drive the filter paper to flip and move. When the lifting plate moves to the left, it drives the pressing plate to move downward and fixes the top of the filter paper near the right side, thereby fixing the position of the filter paper.

[0017] S5: When the filter paper is fixed, the staff manually cranks the handle to rotate it. When the handle rotates, it drives the flip plate to rotate, so as to take out the oily sludge inside the transfer tube and apply it to the bottom of the filter paper.

[0018] S6: Use filter paper with an ultraviolet lamp and compare the fluorescence brightness with that of a sample with known oil content to determine the current oil content of the sludge.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention utilizes the interplay between components such as a feeding motor, crossbar, rectangular chain, side plate, rectangular plate, center plate, translation plate, rubber wheel, linkage block, lower trigger, and upper trigger. When the feeding motor starts, the rectangular chain drives the rubber wheel to move in a rectangular motion, which in turn moves the filter paper to the left. Because the left side of the filter paper adheres to the anti-slip layer on the right side of the processing box, the middle part of the filter paper will bulge. When the linkage block moves to the left, it will also contact the lower trigger, causing the reciprocating rod to insert into the bulging part of the filter paper and turn the filter paper into a vertical position for easier subsequent processing.

[0021] This invention utilizes the interplay of components such as a material-pulling cylinder, connecting rod, guide plate, pressing plate, moving rack, L-shaped clamping plate, movable gear, linkage gear, second crank, first crank, welding plate, grooved wheel, and belt to move the filter paper to the top of the processing box when it is in a vertical position. Oily sludge is then applied to the bottom of the filter paper. Workers can then determine the oil content of the current oily sludge by comparing the fluorescence brightness of samples with known oil content, thus reducing processing costs.

[0041] A method for detecting the oil content of oily sludge using an oil-containing sludge detection device includes the following steps:

[0042] S1: The staff places a stack of filter paper 6 on top of the reset plate 41 and flips the swing limiting plate 38 to fit the top of the filter paper 6 for limiting and ready for use.

[0043] S2: When it is necessary to test the oil content of oily sludge, start the feeding motor 7. When the feeding motor 7 starts, it drives the rubber wheel 19 to move in a concave shape. During the movement, it drives the filter paper 6 to move to the left and starts the lower trigger 37.

[0044] S3: When the lower trigger 37 is started, it drives the reciprocating cylinder 29 to move upward and starts the upper trigger 21, thereby causing the reciprocating rod 28 to move backward and limit the filter paper 6.

[0045] S4: When the filter paper 6 is in a vertical state, the lifting cylinder 49 fixes the vertical filter paper 6, and the pulling cylinder 11 is activated to drive the filter paper 6 to flip and move. When the lifting plate 44 moves to the left, it drives the pressing plate 23 to move downward and fixes the top of the filter paper 6 near the right side, thereby fixing the position of the filter paper 6.

[0046] S5: When the filter paper 6 is fixed, the operator manually cranks the handle 15 to rotate it. When the handle 15 rotates, it drives the flip plate 14 to rotate, so as to remove the oily sludge inside the transfer tube 4 and apply it to the bottom of the filter paper 6.

[0047] S6: Filter paper 6 is used in conjunction with ultraviolet lamp 24, and the fluorescence intensity is compared with that of a sample with known oil content to determine the current oil content of the oily sludge.

[0048] Working principle: First, the operator places a stack of filter paper 6 on top of the reset plate 41 and drives the swing limit plate 38 to adhere to the topmost filter paper 6, thus fixing the height of the filter paper 6. When it is necessary to test the oil content of the oily sludge, the feeding motor 7 is started. The feeding motor 7 drives the adjacent sprocket 33 to rotate through the power output shaft. When the sprocket 33 rotates, it drives the rectangular chain 32 to rotate through the remaining sprockets 33. When the rectangular chain 32 rotates, it drives the locking block to move. When the locking block moves downward, it drives the rubber wheel 19 to move downward. When the locking block moves to the left, it drives the filter paper 6 to move to the left through the rubber wheel 19. Since the filter paper 6 is attached to the anti-slip layer on the right side of the processing box 3, when the filter paper 6 is subjected to external force... When the force moves to the left, the middle part of the filter paper 6 bulges up. When the rubber wheel 19 moves to the left, it drives the linkage block 22 to move synchronously to the left, activating the lower trigger 37. When the lower trigger 37 is activated, the reciprocating cylinder 29 is started. The reciprocating cylinder 29 drives the reciprocating rod 28 to move backward via the power output shaft, inserting into the bulging middle part of the filter paper 6. When the output shaft of the reciprocating cylinder 29 moves to its limit distance, the lifting motor 43 starts, driving the drive gear 42 to rotate. When the drive gear 42 rotates, it drives the lifting rack 30 to move upward. When the lifting rack 30 moves upward, it drives the mounting box 27 to move upward. When the mounting box 27 moves upward, it straightens the filter paper 6 via the reciprocating rod 28, turning the filter paper 6 into a vertical state. When the box 27 contacts the upper trigger 21, the lifting cylinder 49 is activated. The power output shaft of the lifting cylinder 49 drives the lifting plate 44 to move upward. When the lifting plate 44 moves upward, it drives the two clamping plates 47 to move in opposite directions through the cross crank 46, thus fixing the vertical filter paper 6. When the material pulling cylinder 11 is activated, it drives the movable block 60 to move to the left through the power output shaft via the second crank 55 and the first crank 54. The movable block 60 slides along the inner cavity of the guide port, thereby causing the filter paper 6 to flip and move. When the moving rod 48 moves to the left, it contacts the slider 59 and drives the slider 59 to move to the left. When the slider 59 moves to the left, it drives the rack 18 to move to the left. When the rack 18 moves to the left, The rotating gear 56 drives the movable gear 56 to rotate, which in turn drives the grooved wheel 58 on the left side to rotate. The rotation of the grooved wheel 58 on the left side, via belt 26, drives the grooved wheel 58 on the other side to rotate. The rotation of the grooved wheel 58 on the right side drives the linkage gear 52 to rotate. The rotation of the linkage gear 52 drives the moving rack 50 to move downwards. As the moving rack 50 moves downwards, it uses the pressing plate 23 to fix the top of the filter paper 6 near the right side. The operator then uses the handle 15 to rotate the rotating rod 17 90 degrees clockwise, causing the flipping plate 14 to enter the inner cavity of the transmission tube 4. Subsequently, the operator rotates the rotating rod 17 90 degrees counterclockwise, applying the oily sludge from the surface of the flipping plate 14 to the bottom of the filter paper 6. The operator then uses the ultraviolet lamp 24 in conjunction with this process.The fluorescence intensity of filter paper 6 was compared with that of a sample with a known oil content to determine the current oil content of the oily sludge.
