Description

An integrated waste oil decolorization and dehydration machine Technical Field

[0001] This utility model relates to the field of waste oil treatment, specifically to an integrated waste oil decolorization and dehydration machine. Background Technology

[0002] Waste oil contains a large amount of impurities, water, and pigments, and direct discharge will cause serious environmental pollution. Therefore, it needs to be effectively treated and recycled. In waste oil treatment, dehydration and decolorization are two important steps. Dehydration can remove water from waste oil and improve the purity of the oil, while decolorization can remove pigments from waste oil, so that its appearance and quality meet certain standards, thereby realizing the reuse of waste oil.

[0003] Currently, waste oil dehydration and decolorization are typically carried out using separate equipment. In practice, the waste oil first needs to be dehydrated using dehydration equipment, and then the dehydrated waste oil is transported to decolorization equipment for further decolorization. While this method achieves both dehydration and decolorization, the separate nature of the dehydration and decolorization equipment necessitates the installation of pipelines and corresponding waste oil conveying equipment between them. This not only increases the overall footprint of the treatment equipment but also raises the risk of leakage and pollution during different treatment processes. Summary of the Invention

[0004] The purpose of this utility model is to provide an integrated waste oil decolorization and dehydration machine. This equipment reduces the limitations of space on equipment use and reduces the workload and difficulty for operators in operating and monitoring the equipment during waste oil treatment.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] An integrated waste oil decolorization and dehydration machine includes:

[0007] The machine body has a dehydration chamber and a decolorization chamber arranged vertically inside. The dehydration chamber is equipped with a liquid inlet and an air outlet, and the decolorization chamber is equipped with a liquid outlet and a feeding port for adding decolorizing agent.

[0008] The water absorption chamber is filled with hydrophilic and oleophobic modified fiber ball filter media and is located between the dewatering chamber and the decolorization chamber.

[0009] The dehydration chamber and the decolorization chamber are both equipped with heating devices. The decolorization chamber is equipped with a stirring mechanism for stirring the waste oil inside. A filter box is connected to the drain port, and a solenoid valve is provided at the connection between the two. The filter box is equipped with a liquid outlet. The dehydration chamber, the water absorption chamber, and the decolorization chamber can be synchronously connected to each other through a switching mechanism.

[0010] As a further improvement to the above technical solution, the switching mechanism includes a first turntable and a second turntable, both of which are rotatably mounted on the machine body. The machine body is provided with a first drive motor for driving the first and second turntables to rotate synchronously and in the same direction. The first turntable is located between the dehydration chamber and the water absorption chamber. A plurality of first through holes arranged in a circular pattern at equal intervals are opened on the bottom surface of the dehydration chamber and the top surface of the water absorption chamber, and the first through holes on the two are one-to-one. A second through hole is opened on the first turntable for connecting the corresponding first through holes on the dehydration chamber and the water absorption chamber. The second turntable is located between the water absorption chamber and the decolorization chamber. A plurality of third through holes arranged in a circular pattern at equal intervals are opened on the bottom surface of the water absorption chamber and the top surface of the decolorization chamber, and the third through holes on the two are one-to-one. A fourth through hole is opened on the second turntable for connecting the corresponding third through holes on the water absorption chamber and the decolorization chamber. A metal mesh is provided on the fourth through hole. When the corresponding first through holes are connected through the second through hole, the corresponding third through holes are connected through the fourth through hole.

[0011] As a further improvement to the above technical solution, the heating device is an electric heating tube, and the two electric heating tubes are arranged in a wavy pattern along the sides of the dehydration chamber and the decolorization chamber, respectively.

The stirring rods of adjacent stirring units are staggered.

[0013] As a further improvement to the above technical solution, the filter box includes a box body, and a number of filter screens are arranged from top to bottom inside the box body. The filter screens are arranged at equal intervals. An opening for inserting and removing the filter screens inside the box body is provided on the side of the box body, and a flip cover is provided on the opening.

[0016] This invention, through the structural arrangement of a dehydration chamber, a water absorption chamber, and a decolorization chamber on the machine body, combined with a switching mechanism to control the connection state between the three, achieves the effect of dehydrating and decolorizing waste oil with the same equipment, while also reducing the equipment's footprint and minimizing the limitations of space constraints on equipment use. It also reduces the workload and difficulty for operators in operating and monitoring the equipment during waste oil treatment. Furthermore, since the waste oil only flows inside the equipment, it reduces the need for pipelines to transport waste oil to the outside of the equipment, thus reducing the risk of leakage and pollution during waste oil dehydration and decolorization treatment.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0025] Referring to Figures 1-6, this embodiment describes an integrated waste oil decolorization and dehydration machine, comprising a body 1. The body 1 contains a dehydration chamber 2 and a decolorization chamber 3 arranged vertically. The dehydration chamber 2 has a liquid inlet 21 and an air outlet 22. The decolorization chamber 3 has a drain outlet 31 and a feeding port 32 for adding decolorizing agent. A water absorption chamber 4 is located between the dehydration chamber 2 and the decolorization chamber 3, filled with hydrophilic and oleophobic modified fiber ball filter media. Both the dehydration chamber 2 and the decolorization chamber 3 are equipped with heating devices 5. The decolorization chamber 3 has a stirring mechanism 6 for stirring the waste oil within. A filter box 7 is connected to the drain outlet 31, and a solenoid valve 71 is located at the connection point. The filter box 7 has a liquid outlet 72. The dehydration chamber 2, the water absorption chamber 4, and the decolorization chamber 3 can be synchronously connected via a switching mechanism 8.

[0026] Waste oil is transported into the dehydration chamber 2 through the liquid inlet 21. At this time, the dehydration chamber 2, the water absorption chamber 4, and the decolorization chamber 3 are in a disconnected state. The waste oil in the dehydration chamber 2 is heated by the heating device 5 at a temperature between the boiling point of water and the boiling point of oil, so that the water in the waste oil can evaporate into water vapor and be discharged through the vent 22. Then, the dehydration chamber 2, the water absorption chamber 4, and the decolorization chamber 3 are switched from being disconnected to being connected by the switching mechanism 8. Thus, the waste oil that has undergone dehydration treatment in the dehydration chamber 2 flows through the water absorption chamber 4 into the decolorization chamber 3. During this process, the modified fiber ball filter media in the water absorption chamber 4 can absorb the small amount of residual water in the waste oil, reducing the water content of the waste oil entering the decolorization chamber 3. Then, the dehydration chamber 2, the water absorption chamber 4, and the decolorization chamber 3 are switched back to being disconnected by the switching mechanism 8. The decolorizing agent (such as activated clay) is added to the decolorization chamber 3 through the feeding port 32. At the same time, the heating device 5 in the decolorization chamber 3 heats the waste oil and the stirring mechanism 6 stirs the waste oil, which can reduce the viscosity of the waste oil and make the decolorizing agent and the waste oil fully contacted, thereby improving the decolorization effect of the waste oil. After the waste oil is decolorized, the solenoid valve 71 is opened, so that the filter box 7 filters out the impurities formed by the decolorizing agent in the waste oil, and the treated waste oil is discharged through the outlet 72.

[0027] Referring to Figures 2-4, the switching mechanism 8 includes a first turntable 81 and a second turntable 82, both of which are rotatably mounted on the machine body 1. The machine body 1 is equipped with a first drive motor 83 for driving the first turntable 81 and the second turntable 82 to rotate synchronously and in the same direction. The first turntable 81 is located between the dehydration chamber 2 and the water absorption chamber 4. A plurality of first through holes 84 arranged in an annular pattern at equal intervals are formed on the bottom surface of the dehydration chamber 2 and the top surface of the water absorption chamber 4, with each of the first through holes 84 corresponding to the other. The first turntable 81 also has second through holes 85 for connecting the corresponding first through holes 84 on the dehydration chamber 2 and the water absorption chamber 4. The second turntable 82 is located between the water absorption chamber 4 and the decolorization chamber 3. Several third through holes 86 are arranged in a circular pattern at equal intervals on the bottom surface of the water absorption chamber 4 and the top surface of the decolorization chamber 3, and the third through holes 86 on both correspond one-to-one. The second turntable 82 is provided with a fourth through hole 87 for connecting the corresponding third through holes 86 on the water absorption chamber 4 and the decolorization chamber 3. A metal mesh 88 is provided on the fourth through hole 87, which serves to prevent the modified fiber ball filter material from falling from the water absorption chamber 4 into the decolorization chamber 3. When the corresponding first through holes 84 are connected through the second through hole 85, the corresponding third through holes 86 are connected through the fourth through hole 87.

[0028] When the dehydration chamber 2, water absorption chamber 4, and decolorization chamber 3 are sequentially switched from a disconnected state to a connected state, the first drive motor 83 drives the first turntable 81 and the second turntable 82 to rotate synchronously in the same direction at a certain angle until the second through hole 85 on the first turntable 81 moves between the corresponding two first through holes 84, so that the dehydration chamber 2 and the water absorption chamber 4 are connected. At the same time, the fourth through hole 87 on the second turntable 82 moves between the corresponding two third through holes 86, so that the water absorption chamber 4 and the decolorization chamber 3 are connected. This enables the waste oil to flow sequentially between the dehydration chamber 2, the water absorption chamber 4, and the decolorization chamber 3, ensuring the operation of each waste oil treatment.

[0029] In this embodiment, the first drive motor 83 is detachably mounted on the side of the body 1, and the first turntable 81 and the second turntable 82 are both connected to the output shaft of the first drive motor 83 through a gear transmission mechanism 89.

[0030] Referring to Figure 3, the feeding port 32 is provided with a cover 33, which is rotatably connected to the machine body 1 and the two can be magnetically connected, reducing the impact of external environmental factors on the decolorization effect in the decolorization chamber 3.

[0031] Referring to Figure 5, the heating device 5 is an electric heating tube. The two electric heating tubes are arranged in a wave-like pattern along the sides of the dehydration chamber 2 and the decolorization chamber 3, respectively. This not only ensures the heating effect on the waste oil, but also reduces the impact of the installation of the heating device 5 on the flow of waste oil. At the same time, it also reduces the difficulty of setting up the stirring mechanism 6 in the decolorization chamber 3.

[0032] Referring to Figures 5 and 6, the stirring mechanism 6 includes a rotating shaft 61, which is rotatably mounted on the machine body 1. A second drive motor 62 is mounted on the machine body 1 to drive the rotating shaft 61 to rotate relative to the machine body 1. Several stirring units 63 are evenly spaced along the axial direction of the rotating shaft 61. Each stirring unit 63 includes several stirring rods 64, which are arranged at equal angles around the central axis of the rotating shaft 61. The stirring rods 64 of adjacent stirring units 63 are staggered. When stirring is required, the second drive motor 62 drives the rotating shaft 61 to rotate, causing the rotating shaft 61 to drive the stirring rods 64 to rotate, thereby agitating the waste oil and decolorizing agent in the decolorization chamber 3. This ensures that the two substances can fully contact each other, improving the adsorption degree of the decolorizing agent on the pigments in the waste oil and guaranteeing the decolorization treatment effect of the waste oil.

[0033] Referring to Figure 6, the filter box 7 includes a box body 73. Several filter screens 74 are arranged from top to bottom inside the box body 73. The filter screens 74 are arranged at equal intervals. An opening 75 is provided on the side of the box body 73 for inserting and removing the filter screens 74 inside the box body 73. A flip cover 76 is provided on the opening 75 to facilitate the cleaning of the filter box 7 and the replacement of the filter screens 74 inside, thus ensuring the filtration effect of the filter box 7 on the waste oil after dehydration and decolorization treatment.

[0034] To reduce the leakage of waste oil from the casing 73 to the outside through the opening 75, a sealing ring can be installed between the flip cover 76 and the body 1. When the flip cover 76 is flipped up to close the opening 75 and the connection between it and the body 1 is completed by screws, the sealing ring is clamped between the flip cover 76 and the body 1.

[0035] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
