Description

Technical Field

[0001] This utility model relates to the field of waste mineral oil pretreatment technology, specifically to a waste mineral oil pretreatment device. Background Technology

[0002] Various types of waste mineral oil are generated in industrial production and daily life. These used waste mineral oils are classified as hazardous waste because they contain a variety of toxic components and impurities. However, waste mineral oils also have valuable resource attributes. Comprehensive utilization of them can not only alleviate the shortage of mineral resources and the tight supply of oil products in my country to a certain extent, but also significantly reduce the negative impact of industrialization on my country's ecological environment by improving the utilization efficiency of existing resources.

[0003] A search revealed Chinese patent CN222512899U, which discloses a waste mineral oil pretreatment device, including a treatment tank with a support column fixedly connected to its bottom. A filter cylinder is installed so that when waste mineral oil is injected into the treatment tank from the inlet, it is first filtered to remove larger particles. The waste mineral oil is then injected into the treatment tank, and a motor drives a drive gear. Since crown gear two meshes with the top of the drive gear, and crown gear one meshes with the bottom of the drive gear, the rotation of the drive gear simultaneously drives crown gear two and crown gear one to rotate in opposite directions. This, in turn, causes agitator paddles one and two to rotate in opposite directions inside the treatment tank, thus cross-stirring the waste mineral oil inside.

[0004] The above-mentioned patent has the following shortcomings: Since the equipment needs to filter large particles of residue and waste in waste mineral oil through a filter cartridge, after filtration, the filter cartridge needs to be removed and the residue poured out. Since waste mineral oil is relatively viscous, when the filter cartridge is removed and the residue is poured out, the waste mineral oil remaining in the filter cartridge will drip onto the surface of the equipment, causing pollution to the equipment. At the same time, the frequent removal and removal of the filter cartridge results in a high workload and affects production efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a waste mineral oil pretreatment device to solve the technical problems of waste mineral oil easily dripping and contaminating the equipment when the filter cartridge is removed and the slag is poured out, and the high workload and low production efficiency caused by frequent removal and removal of the filter cartridge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste mineral oil pretreatment device, comprising a main body, a cooling mechanism, a slag discharge mechanism, and a stirring mechanism. The slag discharge mechanism includes a filter chamber, with support rods fixedly connected to both sides of the filter chamber. An mounting plate is welded to the top of the support rods, and a first motor is fixed to the top of the mounting plate. A lead screw is provided at the output end of the first motor, and a filter plate is threadedly connected to the lead screw. Scrapers are provided around the filter plate, and a guide rod is provided on one side of the lead screw.

[0007] A slag discharge plate is fixedly connected to the front of the filter chamber, and a fixing frame is provided below the slag discharge plate, on which a slag bucket is placed.

[0008] By adopting the above technical solution, a slag discharge plate is fixedly connected to the front of the filter chamber. The slag discharge plate has a certain tilt angle, which facilitates the smooth discharge of scraped impurities and residues from the filter chamber.

[0009] Furthermore, the cooling mechanism includes a cooling box, and a water pump is fixedly connected inside the cooling box.

[0010] By adopting the above technical solutions, the cooling box facilitates the circulation of the cooling medium and the dissipation of heat, thereby improving the efficiency of the cooling system.

[0011] Furthermore, a water inlet pipe is provided on one side of the water pump, and one end of the water inlet pipe is connected to an annular cooling pipe, with a cooling chamber opened on the outer side of the annular cooling pipe.

[0012] By adopting the above technical solution, the water inlet pipe, as a channel connecting the water pump and the annular cooling pipe, can ensure that the cooling medium flows smoothly from the water pump into the annular cooling pipe.

[0013] Furthermore, one end of the annular cooling pipe is connected to a water outlet pipe, and one end of the water outlet pipe is connected to a water pump.

[0014] By adopting the above technical solution, the annular cooling pipe enables the cooling medium to be distributed more evenly when flowing inside the pipe, ensuring that the waste mineral oil can be cooled evenly in all parts.

[0015] Furthermore, the stirring mechanism includes a second motor, and the output end of the second motor is provided with a drive gear, which meshes with a first crown gear and a second crown gear.

[0016] By adopting the above technical solution, the second motor, as the power core of the stirring mechanism, can provide stable and sufficient driving force for the entire stirring process, thereby improving the quality and efficiency of pretreatment.

[0017] Furthermore, a connecting rod is fixedly connected to the bottom of the first crown gear, and a first stirring paddle is fixedly connected to the outer surface of the connecting rod.

[0018] By adopting the above technical solution, the first crown gear and the connecting rod are fixedly connected, which can ensure that the power of the first crown gear is reliably transmitted to the connecting rod and prevent power interruption or instability caused by loose connection.

[0019] Furthermore, a sleeve rod is fixedly connected to the bottom of the second crown gear, and a second stirring paddle is fixedly connected to the outer surface of the sleeve rod.

[0020] By adopting the above technical solution, when the second motor drives the drive gear to rotate, the drive gear can accurately transmit power to the second crown gear, enabling the second crown gear to rotate stably and precisely.

[0021] Furthermore, a sedimentation cylinder is provided at the bottom of the main body, and a discharge port is provided at the bottom of the sedimentation cylinder.

[0022] By adopting the above technical solution, a sedimentation cylinder is set at the bottom of the main body, which allows the treated waste mineral oil to flow smoothly into the sedimentation cylinder. In the sedimentation cylinder, the waste mineral oil and impurities are further separated. The impurities are deposited at the bottom of the sedimentation cylinder, while the relatively pure waste mineral oil remains in the upper layer, which improves the pretreatment effect of waste mineral oil and provides higher quality raw materials for subsequent processing and utilization.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, by setting up a slag discharge mechanism, uses a first motor to drive the lead screw to rotate, causing the filter plate to move upward along the guide rod, thus carrying out large particles of residue from the filter chamber. This eliminates the need for manual operation, reducing labor intensity and improving production efficiency. When the filter plate rises above the edge of the filter chamber, the inclined filter plate causes the residue to be discharged through the slag discharge plate under gravity and flow into the slag bucket for collection. This makes the slag discharge process smoother, avoids the situation of residue dripping and contaminating the equipment, and ensures the cleanliness and normal operation of the equipment.

[0025] 2. This utility model, by setting up a cooling mechanism and a stirring mechanism, allows the coolant to flow in a ring-shaped cooling pipe, absorbing the heat generated by the equipment, and then flowing back to the water pump through the outlet pipe, forming a circulating cooling system, which improves the reliability and stability of the equipment. The two stirring paddles simultaneously stir the waste mineral oil, which can improve the treatment effect of waste mineral oil, accelerate the reaction speed, and shorten the treatment time.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] A waste mineral oil pretreatment device, such as Figures 1-4 As shown, it includes a main body 1, a cooling mechanism 2, a slag discharge mechanism 3, and a stirring mechanism 4. The slag discharge mechanism 3 includes a filter chamber 301. Support rods 302 are fixedly connected to both sides of the filter chamber 301. A mounting plate 303 is welded to the top of the support rods 302. A first motor 304 is fixed to the top of the mounting plate 303. A lead screw 305 is provided at the output end of the first motor 304. A filter plate 306 is connected to the lead screw 305 by threads. Scrapers 307 are provided around the filter plate 306. A guide rod 308 is provided on one side of the lead screw 305.

[0033] A slag discharge plate 309 is fixedly connected to the front of the filter chamber 301. A fixing frame 311 is set below the slag discharge plate 309. A slag bucket 310 is placed on the fixing frame 311. The slag discharge plate 309 has a certain tilt angle to facilitate the smooth discharge of scraped impurities and residues from the filter chamber 301. The slag bucket 310 is placed on the fixing frame 311, located below the slag discharge plate 309, and is used to collect the discharged impurities and residues, preventing impurities and residues from scattering and keeping the surrounding environment of the equipment clean.

[0034] See Figure 1 , Figure 2 , Figure 3 The cooling mechanism 2 includes a cooling box 201, and a water pump 202 is fixedly connected inside the cooling box 201. The cooling box 201 facilitates the circulation of the cooling medium and the dissipation of heat, thereby improving the efficiency of the cooling system. The water pump 202 can ensure the continuity and stability of the cooling effect and avoid the cooling medium from flowing poorly due to insufficient power, which would affect the cooling effect of the waste mineral oil.

[0035] See Figure 3 , Figure 4 A water inlet pipe 203 is provided on one side of the water pump 202. One end of the water inlet pipe 203 is connected to an annular cooling pipe 205. A cooling chamber 204 is provided on the outside of the annular cooling pipe 205. The water inlet pipe 203 serves as a channel connecting the water pump 202 and the annular cooling pipe 205, ensuring that the cooling medium flows smoothly from the water pump 202 into the annular cooling pipe 205. The cooling chamber 204 is located on the outside of the annular cooling pipe 205, providing installation space for the annular cooling pipe 205.

[0036] See Figure 3 , Figure 4 One end of the annular cooling pipe 205 is connected to the water outlet pipe 206, and one end of the water outlet pipe 206 is connected to the water pump 202. The annular cooling pipe 205 enables the cooling medium to be distributed more evenly when flowing in the pipe, ensuring that the waste mineral oil can be cooled evenly in all parts. The water pump 202 provides a power source for the circulation of the cooling medium, ensuring that the cooling medium can flow stably in the circulation system composed of the annular cooling pipe 205 and the water outlet pipe 206.

[0037] See Figure 3 , Figure 4 The stirring mechanism 4 includes a second motor 401. The output end of the second motor 401 is provided with a drive gear 402. The drive gear 402 meshes with a first crown gear 403 and a second crown gear 406. The second motor 401 serves as the power core of the stirring mechanism 4, providing stable and sufficient driving force for the entire stirring process, thereby improving the quality and efficiency of pretreatment. By meshing with the first crown gear 403 and the second crown gear 406, the drive gear 402 achieves a change in the direction of power, allowing the two stirring paddles to rotate in opposite directions.

[0038] See Figure 3 , Figure 4A connecting rod 404 is fixedly connected to the bottom of the first crown gear 403, and a first stirring paddle 405 is fixedly connected to the outer surface of the connecting rod 404. The first crown gear 403 and the connecting rod 404 are fixedly connected, which can ensure that the power of the first crown gear 403 is reliably transmitted to the connecting rod 404, and prevent power interruption or instability caused by loose connection. The first stirring paddle 405 can effectively promote the mixing or reaction of waste mineral oil with other substances, improve the treatment effect of waste mineral oil, and make the treated waste mineral oil of higher quality, which is more conducive to subsequent processing and utilization.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The bottom of the second crown gear 406 is fixedly connected to a sleeve rod 407, and the outer surface of the sleeve rod 407 is fixedly connected to a second stirring paddle 408. When the second motor 401 drives the drive gear 402 to rotate, the drive gear 402 can accurately transmit power to the second crown gear 406, so that the second crown gear 406 can rotate stably and accurately. The second stirring paddle 408 is fixedly connected to the outer surface of the sleeve rod 407 and rotates with the rotation of the sleeve rod 407, so that the waste mineral oil is fully mixed and stirred in the mixing chamber.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The bottom of the main body 1 is provided with a sedimentation cylinder 5, and the bottom of the sedimentation cylinder 5 is provided with a discharge port 6. The sedimentation cylinder 5 at the bottom of the main body 1 allows the treated waste mineral oil to flow smoothly into the sedimentation cylinder 5. In the sedimentation cylinder 5, the waste mineral oil and impurities are further separated. The impurities are deposited at the bottom of the sedimentation cylinder 5, while the relatively pure waste mineral oil remains in the upper layer, which improves the pretreatment effect of the waste mineral oil and provides higher quality raw materials for subsequent processing and utilization. The discharge port 6 at the bottom of the sedimentation cylinder 5 allows the waste mineral oil to flow out smoothly under the action of gravity when the treated waste mineral oil needs to be discharged.

[0041] The implementation principle of this utility model is as follows: First, after the waste mineral oil is filtered through the filter chamber 301, the first motor 304 drives the lead screw 305 to rotate, causing the filter plate 306 to move upward along the guide rod 308, carrying out the large particles of residue in the filter chamber 301. At the same time, the scraper 307 scrapes off the residue adhering to the inner wall of the filter chamber 301. Then, when the filter plate 306 rises above the edge of the filter chamber 301, the inclined filter plate 306 causes the residue to be discharged through the slag discharge plate 309 and flow into the slag bucket 310 for collection. After that, the first motor 304 drives the lead screw 305 to rotate again, causing the filter plate 306 to descend for reuse.

After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
