Technical Field

[0001] The utility model relates to the technical field of oil sludge concentration, in particular to an industrial waste oil sludge concentration device. Background Technique

[0002] Industrial waste oil sludge concentration devices are mainly used for concentrating industrial waste oil sludge. Through specific processes and technologies, such devices can effectively remove moisture, impurities, etc. in the waste oil sludge, thereby reducing its volume and increasing its density, making it convenient for subsequent transportation, storage, and treatment. The concentrated waste oil sludge not only reduces the impact on the environment but also facilitates resource recovery and utilization. Therefore, industrial waste oil sludge concentration devices are of great significance in both environmental protection and resource utilization.

[0003] In the existing coal chemical wastewater treatment, in the processes of oil sludge separation and concentration, technologies such as gravity sedimentation and centrifugal concentration are mostly used. Centrifugal treatment requires a large amount of energy to generate a large enough centrifugal force. This high energy consumption characteristic makes centrifugal concentration costly, with a complex process and serious energy consumption when treating waste oil sludge. Moreover, the volume of the sludge after concentration is large, making it inconvenient to collect, and subsequent treatment and transportation are also inconvenient. In summary, there is an urgent need for a low-cost device for separating, concentrating, and dehydrating oil sludge in coal chemical wastewater to solve the above problems. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an industrial waste oil sludge concentration device.

[0005] The technical solution of the utility model is: an industrial waste oil sludge concentration device, including an oil sludge separation housing, a blanking housing, and a concentration housing arranged in sequence from top to bottom; both sides of the blanking housing are arc-shaped walls, a blanking plate is rotatably arranged in the blanking housing, and a first opening and a guiding groove communicated with the concentration housing through a pipeline are arranged on the arc-shaped wall. A compressed air column is arranged in the guiding groove, one end of the blanking plate is provided with a slider slidably connected with the guiding groove, and the slider is fixedly connected with the other end of the compressed air column; a stirring rod is horizontally arranged in the oil sludge separation housing; a driving device for driving the blanking plate to rotate is arranged in the blanking housing; a sliding rod is horizontally arranged in the concentration housing, and an extrusion plate assembly driven by the compressed air column is arranged on the sliding rod.

[0006] Furthermore, the extrusion plate assembly includes two first extrusion plates vertically arranged on the sliding rod, two second extrusion plates located on the upper and lower sides of the first extrusion plates, and a first adjusting plate and a second adjusting plate with one end hinged to the first extrusion plate and the other end hinged to the second extrusion plate; an airbag is arranged vertically between the first adjusting plate and the second adjusting plate on the same side, the airbag is communicated with the compression air column through a pipeline, and a solenoid valve is arranged in the pipeline; a temporary storage chamber is arranged at the bottom of the first opening; the temporary storage chamber is communicated with the middle of the second extrusion plate through a blanking hose, and a pump body for pumping materials is arranged at the outlet of the blanking hose.

[0007] Explanation: The linkage of the blanking plate, the compression air column and the airbag in the concentration area realizes the blanking of the sludge and simultaneously drives the first extrusion plate and the second extrusion plate, successively realizing the pressure filtration of the sludge in the horizontal and vertical directions. The utility model can realize the drive of the concentration equipment by using the gravity generated during the blanking process of the sludge itself. No additional motor configuration is required during the concentration process, effectively reducing the motor energy consumption. And through the extrusion dehydration by the pressing plate, the excess water and impurities in the sludge can be quickly removed, and the volume of the dehydrated sludge can be made smaller, which not only improves the treatment efficiency, but also facilitates the subsequent treatment and transportation, and helps to reduce the cost in the subsequent treatment process.

[0008] Furthermore, a first rotating wheel is arranged on the concentration housing, the sliding rod is a threaded rod with opposite threads on both sides symmetric about the middle, and one side of the sliding rod is connected to the inner wall of the concentration housing through a torsion spring shaft, the other side of the sliding rod penetrates through the concentration housing and is connected to the first rotating wheel, and the first extrusion plate is threadedly sleeved on the sliding rod; and one end of the stirring rod penetrates through the oil sludge separation housing and is provided with a second rotating wheel belt-drivenly connected to the first rotating wheel.

[0009] Explanation: The above settings can realize the linkage of the oil sludge separation process and the concentration process by the linkage between the threaded rod, the first rotating wheel, the second rotating wheel and the transmission belt, reducing the energy consumption generated by driving the stirring device during the stirring and standing process of the oil sludge separation. The setting of the torsion spring shaft can store energy for the threaded rod during the pressure filtration and concentration process. Under the action of the torsion spring shaft, the threaded rod rotates in reverse to drive the second rotating wheel to rotate, thereby realizing the stirring treatment of the new waste oil sludge, and further improving the concentration efficiency of the equipment for the oil sludge.

[0012] Furthermore, the driving device is an elastic material arranged in the guide groove; it can be understood that the length of the elastic material in the initial state without compression is equal to the length of the guide groove of the arc plate on this side;

[0013] Description: The above settings can adjust the angle of the blanking plate by using the elastic restoring force of the elastic material, further improving the blanking efficiency. This part of the setting can also effectively replace the second driving motor, achieving the purpose of saving the equipment usage cost.

[0014] Furthermore, on one side of the bottom of the oil sludge separation housing close to the compressed air column, there is a second opening for blanking; a solenoid valve is provided at the second opening, and a viewing window is provided on the oil sludge separation housing;

[0017] Description: The separated oil sludge contains less grease, and the grease in the oil sludge is corrosive to the filter cloth and other components. Directly treating the oil-containing sludge for a long time may shorten the service life of the equipment. The setting of the anti-corrosion filter cloth can effectively avoid the corrosion damage of the grease to the equipment, thereby extending the service life of the equipment.

[0018] The beneficial effects of the present utility model are:

[0019] (1) Through the coordinated action of the blanking housing and the concentration housing, the present utility model realizes the removal of moisture in the sludge by the gravity drive of the sludge itself during the blanking process. The whole process does not require additional motor configuration, effectively reducing the motor energy consumption, thereby reducing the cost during the treatment process; and using the extrusion plate assembly for squeezing dehydration can make the volume of the dehydrated sludge smaller, facilitating subsequent treatment and transportation.

Detailed Description of the Embodiments

[0027] The following further detailed description of the present utility model is made in combination with the specific embodiments to better reflect the advantages of the present utility model.

[0028] Embodiment 1: As Figure 1 shown, an industrial waste oil sludge concentration device includes a sludge separation housing 2, a blanking housing 1, and a concentration housing 3 arranged in sequence from top to bottom; both sides of the blanking housing 1 are arc walls 22, as Figure 2 , Figure 3As shown, a blanking plate 21 is rotatably arranged in the blanking housing 1. A first opening 220 communicating with the concentration housing 3 through a pipeline is provided on one of the arc-shaped walls 22. A guide groove 221 is provided on the inner wall of the other arc-shaped wall 22. A compressed air column 222 is arranged in the guide groove 221. One end of the blanking plate 21 is provided with a slider slidably connected to the guide groove 221, and the slider is fixedly connected to the other end of the compressed air column 222; A stirring rod 23 is horizontally arranged in the sludge separation housing 2; A driving device for driving the rotation of the blanking plate is arranged in the blanking housing 1; A sliding rod 31 is horizontally arranged in the concentration housing 3, and an extrusion plate assembly driven by the compressed air column 222 is arranged on the sliding rod 31; In this embodiment, a temporary storage cavity is provided at the bottom of the first opening 220; The temporary storage cavity is communicated with the middle of the second extrusion plate 33 at the top through a blanking hose; A pump body for pumping materials is provided at the outlet of the blanking hose.

[0029] The extrusion plate assembly includes two first extrusion plates 32 arranged vertically on the sliding rod 31, two second extrusion plates 33 located on the upper and lower sides of the first extrusion plates 32, and a first adjusting plate 331 and a second adjusting plate 332 with one end hinged to the first extrusion plate 32 and the other end hinged to the second extrusion plate 33; An airbag 333 is arranged vertically between the first adjusting plate 331 and the second adjusting plate 332 on the same side. The airbag 333 is communicated with the compressed air column 222 through a pipeline, and a solenoid valve is arranged in the pipeline; Filter holes for water to pass through are provided on the bottom second extrusion plate 33.

[0030] One side of the bottom of the sludge separation housing 2 close to the compressed air column 222 has a second opening 223 for blanking; A solenoid valve is provided at the second opening 223, and a viewing window is provided on the sludge separation housing 2; The driving device in this embodiment uses a commercially available driving motor, which is called the second driving motor in this embodiment; This embodiment also includes a first driving motor for driving the stirring rod 23 to stir.

[0031] The working principle of this embodiment is as follows: First, use an air pump to inflate the inside of the compressed air column 222 until the compressed air column 222 fills the guiding groove 221. Then, introduce the waste oil sludge into the oil sludge separation housing 2, drive the first drive motor to rotate the stirring rod 23 for stirring, so that the oil droplets, organic substances and suspended substances in the oil sludge form flocculent substances. Then, let it stand for 1.5 h. After observing through the viewing window that the waste oil sludge is stratified, open the solenoid valve. At this time, the sludge at the bottom enters the blanking housing 1 through the second opening 223. When it is observed that the bottom sludge is discharged completely, close the solenoid valve. As the sludge enters, the right side of the blanking plate 21 tilts downward under the action of gravity, realizing the extrusion of the compressed air column 222. At this time, the gas in the compressed air column 222 enters the airbag 333, causing the airbag 333 to expand, driving the first pressing plates 32 on both sides of the sliding rod 31 to move towards each other. The sludge enters the temporary storage cavity along the first opening 220 and then enters the concentration housing 3 along the blanking hose, thus realizing the sludge blanking operation. Then, after the sludge is blanked, the blanking plate 21 returns. Use the second drive motor to drive the blanking plate 21 to move in the reverse direction along the guiding groove 221. Through the combined action of gravity and the second drive motor, the two pressing plates move towards each other and relatively, realizing the alternating extrusion of the sludge by the first pressing plate 32 and the second pressing plate 33. Thus, the water in the sludge is extruded, and then the water is discharged along the water outlet provided at the bottom of the concentration housing, realizing the process of rapid and efficient oil sludge dehydration. Finally, the mud residue after the mud-water separation is collected uniformly.

[0032] Embodiment 2: This embodiment is basically the same as Embodiment 1. The difference is that, not shown in the figure, in this embodiment, the pressing plate assembly can be composed of two pressing plates slidably arranged on the sliding rod. In this embodiment, the airbag 333 is sleeved on the sliding rod and both ends are connected to the two pressing plates;

[0033] The working principle of this embodiment is as follows: As the sludge enters, the right side of the blanking plate 21 tilts downward under the action of gravity, realizing the extrusion of the compressed air column 222. At this time, the gas in the compressed air column 222 enters the airbag 333, causing the airbag 333 to expand, driving the pressing plates 32 on both sides of the sliding rod 31 to move away from each other. The sludge enters the temporary storage cavity along the first opening 220 and then enters the concentration housing 3 along the blanking hose, thus realizing the sludge blanking operation. Then, after the sludge is blanked, the blanking plate 21 returns to the horizontal position. Use the second drive motor to drive the blanking plate 21 to move in the reverse direction along the guiding groove 221. The compressed air column 222 continues to expand, and the gas in the airbag 333 decreases, causing the pressing plates to move towards each other.

[0034] Embodiment 3: This embodiment is basically the same as Embodiment 1. The difference is that, as Figure 4As shown in the figure, a first rotating wheel 34 is provided on the concentration housing 3. The sliding rod 31 is a threaded rod with opposite threads on both sides symmetric about the middle, and one side of the sliding rod 31 is connected to the inner wall of the concentration housing 3 through a torsion spring shaft. The other side of the sliding rod 31 penetrates the concentration housing 3 and is connected to the first rotating wheel 34. The first pressing plate 32 is threadedly sleeved on the sliding rod 31. One end of the stirring rod 23 penetrates the sludge separation housing 2 and is provided with a second rotating wheel 231 that is belt-drivenly connected to the first rotating wheel 34.

[0035] Different from Embodiment 1, the working principle of this embodiment is as follows: The first pressing plates 32 on both sides of the sliding rod 31 move towards each other to drive the rotation of the sliding rod 31, causing the first rotating wheel 34 to rotate. Under the combined action of the transmission belt and the second rotating wheel 231, the stirring rod 23 is driven. At the same time, the torsion spring shaft on one side of the sliding rod 31 is used to further drive the sliding rod 31. By alternately reversing the stirring, the sludge separation efficiency of the equipment can be effectively improved. Moreover, in this embodiment, the setting of the transmission belt and the second rotating wheel 231 can replace the first driving motor in Embodiment 1 to drive the stirring rod 23, further reducing the driving cost of the stirring rod 23.

[0036] Embodiment 4: This embodiment is basically the same as Embodiment 1, except that, as Figure 5 shown, a protective curtain 2211 is provided on the guide groove 221. A convex block is provided in the middle of one side of the blanking plate 21. The convex block is slidably arranged in the guide groove 221 and is fixedly connected to the upper and lower protective curtains 2211 respectively. Brush hairs are provided on both sides of the blanking plate 21.

[0037] Different from Embodiment 1, the working principle of this embodiment is as follows: During the rotation of the blanking plate 21, the brush hairs clean the inner wall of the arc-shaped wall 22. The setting of the protective curtain 2211 on the other side can ensure that no impurities enter the guide groove 221 during the rotation of the blanking plate 21, reducing the loss of the equipment.

[0038] Embodiment 5: This embodiment is basically the same as Embodiment 1, except that the driving device is an elastic material arranged in the guide groove 221. It can be understood that the elastic material is any one of commercially available polymer elastomers, silicone rubbers, and elastic metals. In this embodiment, a polymer elastomer is selected as the elastic material.

[0039] Different from Embodiment 1, the working principle of this embodiment is as follows: The self-recovery force of the elastic material is used to adjust the position of the blanking plate 21, so that it can effectively return to the initial state (i.e., the state when the sliding block of the blanking plate 21 is at the top of the guide groove 221) after the blanking extrusion. This part of the setting can effectively replace the second driving motor, achieving the purpose of saving the equipment usage cost.

[0040] Example 6: This example is basically the same as Example 1, except that an anti-corrosion filter cloth is provided on the side of the first extrusion plate 32 and the second extrusion plate 33 in contact with the sludge; the anti-corrosion filter cloth uses a commercially available steel wool filter cloth.
