Description

Technical Field

[0001] This utility model relates to the field of oil and gas field soil remediation and oil sludge treatment, specifically to an automatic bagging device for sorting and bagging oil sludge and contaminants in oily soil. Background Technology

[0002] Currently, oil-contaminated soil in oil and gas fields is remediated using chemical oxidation or microbial techniques. The process flow is as follows: oil-contaminated soil → pretreatment → chemical dosing and mixing → curing. Oil-contaminated soil contains some oil sludge and contaminants generated during oil and gas field production. Oil sludge is debris in oil-contaminated soil, which is paste-like, exists in clumps in the soil, and has a high oil content. Contaminants are oil-absorbing felts, woven bags, and other debris that are contaminated with oil, characterized by their large volume and light weight. These materials can affect the soil remediation effect and efficiency. Therefore, in the remediation process, the oil-contaminated soil must be pretreated before chemical dosing and mixing for remediation. Currently, the pretreatment methods for oil sludge and contaminants in oil-contaminated soil are manual sorting and ALLU mechanical separation. Manual sorting is clean and thorough, but has low throughput and high labor costs. ALLU mechanical separation has a large throughput, but oil sludge and contaminants can become entangled in the ALLU crushing and screening hopper, requiring regular manual unclogging, which is inconvenient. Both methods require manual bagging and storage of the sorted oil sludge and contaminants, which must then be safely disposed of by a qualified third-party organization. Overall, the current pretreatment methods for oil-contaminated soil have high labor costs and low efficiency.

[0003] Based on this, and building upon previous research, this utility model provides an automatic bagging device for sorting and packaging oil sludge and contaminants in oily soil. It employs automatic feeding, cutting and crushing, sorting, and automatic bagging to achieve efficient and precise sorting of oil sludge and contaminants in oily soil, thereby improving pretreatment efficiency and ensuring soil remediation effectiveness.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide an automatic bagging device for sorting and bagging oil sludge and contaminants in oily soil, so as to solve the problems of high labor costs and incomplete sorting in the existing ALLU mechanical separation method or manual sorting method.

[0006] To achieve the above objectives, this utility model provides an automatic bagging device for sorting and bagging oil sludge and contaminants in oily soil, comprising: a feeding mechanism, a sorting mechanism, and a discharging mechanism; the sorting mechanism is located between the feeding mechanism and the discharging mechanism;

[0007] The sorting mechanism includes a sorting roller shaft and a transition plate. The sorting roller shaft is provided with sorting roller teeth. The transition plate is located between the sorting roller shaft and the feeding mechanism. The sorting roller shaft is located between the transition plate and the discharging mechanism.

[0008] Specifically, the feeding mechanism includes a feeding conveyor belt and a feeding trough. The feeding conveyor belt is disposed between the transition plate and the feeding trough. The end of the feeding conveyor belt near the transition plate is located above the transition plate. The feeding port of the feeding trough is provided with a cutter and a feeding claw. The cutter is located inside the feeding claw.

[0009] Specifically, the feeding conveyor belt is inclined, with the end near the transition plate being at a higher position.

[0010] Specifically, the transition plate is inclined, with the end near the feeding mechanism being at a lower position, and the higher end of the transition plate is provided with gaps that cooperate with the sorting roller teeth.

[0011] Specifically, the discharge mechanism includes: an oil sludge conveyor belt and a secondary soil conveyor belt; one end of the oil sludge conveyor belt is located below the sorting roller shaft, and the secondary soil conveyor belt is located below the oil sludge conveyor belt.

[0012] Specifically, the sludge conveyor belt is a roller conveyor belt with gaps between the rollers.

[0013] Specifically, the secondary soil conveyor belt is located below one end of the sludge conveyor belt, and an inclined chute is also provided below the sludge conveyor belt.

[0014] The lower end of the chute is connected to the secondary soil conveyor belt, and the upper end is connected to the lower part of the sludge conveyor belt away from the secondary soil conveyor belt.

[0015] Specifically, a primary soil conveyor belt is provided below the lower end of the transition plate.

[0016] The advantages of this utility model are specifically reflected in the following aspects:

[0017] (1) The sorting mechanism of this utility model is located between the feeding mechanism and the discharging mechanism; the feeding mechanism transports the oily soil to the sorting mechanism, which can perform primary sorting of the oily soil, automatically separating the oily sludge and contaminants from the soil and bringing them to the discharging mechanism. During operation, the discharging mechanism can perform secondary sorting of the oily soil. Operators only need to collect the sorted oily sludge and contaminants at the discharge port of the discharging mechanism. The sorted soil can be transported to a designated location for remediation. The entire sorting process of this utility model does not require human intervention, which can significantly reduce labor intensity and save labor costs.

[0018] (2) This utility model is equipped with an inclined transition plate, which allows soil lumps with smaller particle sizes to slide off the material being transported by the feeding conveyor belt and be transported out onto the primary soil conveyor belt. Because the transition plate has pores, when the sorting rollers rotate, the sorting roller teeth pass through the pores on the transition plate, which can carry the sludge and contaminants from the transition plate to the sludge conveyor belt. The sludge and contaminants pass through the specific gaps between the rollers of the sludge conveyor belt, which causes soil lumps with smaller particle sizes to automatically fall and separate from the gaps, further realizing the automatic sorting effect of sludge and contaminants and soil lumps. In addition, this utility model realizes the automatic bagging of sorted sludge and contaminants by setting ton bags under the sludge conveyor belt. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0022] refer to Figure 1This utility model provides an automatic bagging device for sorting and bagging oil sludge and contaminants in oily soil, including a feeding mechanism, a sorting mechanism, and a discharging mechanism. The sorting mechanism is located between the feeding mechanism and the discharging mechanism and is mainly used for automatically sorting oil sludge and contaminants. The sorting mechanism includes a sorting roller shaft 4 and a transition plate 5. The sorting roller shaft 4 is located between the transition plate 5 and the discharging mechanism. The high end of the transition plate 5 is provided with holes that cooperate with the sorting roller teeth 3. The sorting roller shaft 4 is provided with sorting roller teeth 3 evenly spaced along its circumference. The sorting roller shaft 4 can drive the sorting roller teeth 3 to rotate together. The material passes through the holes on the transition plate 5 to push the sludge and contaminants that fall onto the surface of the transition plate 5 into the plate. On the other hand, under the action of the sorting roller teeth 3, the sludge lumps and contaminants in the soil are further broken up and separated. The transition plate 5 is located between the sorting roller shaft 4 and the feeding mechanism, and is at an angle of 20 to 25° to the horizontal plane, with the end closer to the feeding mechanism being at a lower position. After the material transported by the feeding mechanism falls onto the transition plate 5, the sludge and contaminants will remain on the transition plate 5, and soil lumps with a particle size of less than 10 mm will slide down the transition plate 5. In this embodiment, the angle between the transition plate 5 and the horizontal direction is preferably 20°.

[0023] The feeding mechanism includes a feeding conveyor belt 7 and a feeding trough 9. The feeding conveyor belt 7 is disposed between the transition plate 5 and the feeding trough 9. The end of the feeding conveyor belt 7 near the transition plate 5 is located above the transition plate 5, and is used to transport the material in the feeding trough 9 to the transition plate 5. The feeding conveyor belt 7 is inclined, with its end near the discharge mechanism being at a higher position. The feeding conveyor belt 7 is preferably a commercially available belt conveyor, with a concave center and convex sides. The surface of the conveyor belt is roughened to prevent material from slipping during operation. The feeding trough 9... The feed inlet is equipped with a feeding claw 16, a drive shaft 15, and a cutter 8. The cutter 8 is located inside the feeding claw 16. The feeding claw 16 is made of commercially available steel and is mounted on the drive shaft 15 with an installation spacing of 30-50mm. Each feeding claw 16 consists of several curved claw blades, preferably 6 claw blades. The straight length of the claw blades is 200-300mm, which is used to feed the material into the feed trough 9, initially breaking up large pieces of oil sludge and contaminants in the oily soil to separate them and facilitate subsequent sorting. The cutter 8 is made from commercially available and mature harvesting machinery components, including blades, blade guards, angle steel, and guide strips. The blades are hardened and galvanized to improve their durability. To achieve maximum stability and height control, the blade guard is bolted to the top and bottom of the angle steel and supported by the guide strips. The blade guard has upper and lower cutting edges to balance the force on various parts, ensuring smooth cutter operation. During operation, the cutter 8 moves horizontally, alternating between extension and retraction, at a speed of 3 seconds per cycle. The blade installation spacing is 30-50mm. Each cutter assembly consists of one connecting strip with a crimp nut, three blades, and ten pre-coated screws. Preferably, the cutter 8 uses a double-layer installation method, which ensures balanced blade force and sufficient cutting of the material, breaking large blocks into smaller particles.

[0024] The discharge mechanism includes: a sludge conveyor belt 1 and a secondary soil conveyor belt 11; one end of the sludge conveyor belt 1 is located below the sorting roller shaft 4, and the secondary soil conveyor belt 11 is located below the sludge conveyor belt 1; the sludge conveyor belt 1 is a roller conveyor belt made of stainless steel, with a 10-20mm gap between the rollers to facilitate the soil from secondary sorting falling onto the lower secondary soil conveyor belt 11; a ton bag is installed below the end of the sludge conveyor belt 1 away from the sorting roller shaft 4, allowing material to fall from the discharge port of the sludge conveyor belt 1 into the ton bag, which can be replaced when full. An inclined chute 10 is also provided between the sludge conveyor belt 1 and the secondary soil conveyor belt 11; the lower end of the chute 10 is connected to the secondary soil conveyor belt 11, and the higher end is located below the end of the sludge conveyor belt 1 away from the sorting roller shaft 4. The chute 10 is used to transport soil clumps falling between the rollers of the sludge conveyor belt 1 to the secondary soil conveyor belt 11;

[0025] Furthermore, a primary soil conveyor belt 13 is provided below the lower end of the transition plate 5. The primary soil conveyor belt 13 is mainly used to transport soil lumps with a particle size of less than 10mm that roll off the transition plate 5. The soil lumps of both particle sizes are finally transported to one side of the device via the soil conveyor belt for subsequent chemical remediation treatment.

[0026] Preferably, baffles can be provided on both sides of the conveyor belt, transition plate 5 and feed chute 9 to prevent materials from falling from the sides of the conveyor belt or plate during the material transportation process.

[0027] Furthermore, this utility model can also include a control room 12 to provide a control system for the operation of the entire system. The control room 12 is equipped with a space for one person to operate, as well as ventilation, lighting, and heating / cooling facilities to ensure occupational health and safety.

[0028] The working process in this embodiment of the utility model is as follows:

[0029] After being crushed by the feeding claw 16 and the cutter 8, the material is transported to the transition plate 5 by the feeding conveyor belt. Soil lumps with a particle size of less than 10mm slide down to the primary soil conveyor belt 13, while the remaining material remains on the transition plate 5. The sorting roller shaft 4 drives the sorting roller teeth 3 to rotate, transferring the material remaining on the transition plate 5 to the sludge conveyor belt 1. At this time, soil lumps with a particle size between 10 and 20mm fall from the gap of the sludge conveyor belt 1 onto the chute 10 below, and slide down the chute 10 to the secondary soil conveyor belt 11. The sludge and contaminants fall from the discharge end of the sludge conveyor belt 1 into the ton bag below. The soil lumps on the primary soil conveyor belt 13 and the secondary soil conveyor belt 11 are collected and sent to a designated location for subsequent chemical remediation treatment.
