Description

Technical Field

[0001] The utility model belongs to the technical field of scrapped motor vehicle treatment, and in particular relates to an intelligent zero-discharge treatment device for oil and sewage of scrapped motor vehicles. Background Art

[0002] Zero-emission treatment of waste oil and wastewater from scrapped motor vehicles (LEVEL) refers to the environmentally friendly treatment of waste oil and wastewater generated by scrapped vehicles. With social development and the increasing number of vehicles on the road, the treatment of these waste oil and wastewater from ELVs is becoming increasingly problematic. To minimize their negative impact on the environment, effective measures are needed to achieve zero emissions.

[0003] After searching, in the prior art, Chinese patent announcement number: CN208395109U, authorization date: 2019-01-18, discloses a waste oil collection device for scrapped motor vehicles, including a collection barrel and a carrier vehicle placed at the bottom of the collection barrel, the collection barrel is detachably mounted with a barrel cover, the middle of the barrel cover is mounted with an oil hopper to prevent waste oil from splashing, a columnar isolation layer is detachably mounted in the collection barrel, filter screens are mounted on the upper and lower surfaces of the isolation layer, and the particle size of the filter screen on the upper surface is larger than the particle size of the filter screen on the lower surface, a heating device is provided inside the isolation layer, the heating device is a grid-shaped heating wire, and an alarm is also provided on the heating device, an oil outlet with a valve is provided on the collection barrel, and the filter screen on the isolation layer and the heating device are used in conjunction, so that the waste oil can be processed and refined, the waste residue can be removed, and the quality of the waste oil is ensured.

[0004] However, the device still has the following defects: although the block-shaped waste oil can be melted by the heating device, so that the melted waste oil flows into the lower part of the isolation layer, and is filtered again by the filter mesh on the lower surface of the isolation layer and collected in the collection barrel, when the waste oil is processed, only simple filtration and collection of the waste oil can be achieved, and the waste oil still contains other impurities. This makes the subsequent treatment of the waste oil likely to result in part of the waste being able to be discharged due to the large amount of impurities, resulting in waste oil waste, thereby causing certain pollution and damage to the environment. At the same time, there is also some liquid containing water in the scrapped motor vehicle, and direct discharge will also increase the pollution to the environment. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] The present invention provides an intelligent zero-discharge treatment device for scrapped motor vehicle oil and wastewater, including a box 1, for example, Figure 1-Figure 5 shown.

[0027] A waste oil treatment tank 2 and a wastewater treatment tank 3 are provided on the outside of the box body 1. A partition plate 7 is fixedly connected to the inside of the box body 1, and the partition plate 7 is located at the center of the box body 1. A mounting groove 41 is opened on the inside of the box body 1, and a heating plate 42 is provided on the inside of the mounting groove 41. A filling mechanism 6 is provided between the box body 1 and the waste oil treatment tank 2. A first treatment mechanism 5 is provided on the inside of the waste oil treatment tank 2, and a second treatment mechanism 8 is provided on one side of the box body 1.

[0028] The first processing mechanism 5 includes a mounting plate 51 arranged on the upper side of the waste oil treatment tank 2, and a servo motor 52 is fixedly connected to the upper side of the mounting plate 51. The output end of the servo motor 52 passes through the mounting plate 51, and the output end of the servo motor 52 is connected to a stirring rod 53 through a coupling. The stirring rod 53 is arranged on the inner side of the waste oil treatment tank 2. A filling hole 54 is provided on the upper side of the mounting plate 51, and an insertion rod 55 is fixedly connected to the lower side of the mounting plate 51. A slot 56 is provided on the upper side of the waste oil treatment tank 2, and the insertion rod 55 is movably inserted into the inner side of the slot 56.

[0029] The second processing mechanism 8 includes a connecting block 81 fixedly connected to the inner side of the box body 1. The connecting block 81 is fixedly connected to the wastewater treatment tank 3 on the side away from the box body 1. The two sides of the connecting block 81 are respectively connected to the interior of the box body 1 and the wastewater treatment tank 3. A placement groove 82 is provided on the upper side of the wastewater treatment tank 3. A thermoelectric cooling plate 83 is provided on the inner side of the placement groove 82, and the thermoelectric cooling plate 83 is fixedly connected to the upper side of the wastewater treatment tank 3. A one-way valve 84 is provided on the outer side of the connecting block 81.

[0030] Specifically, the partition plate 7 can divide the interior of the box body 1 into two chambers, one of which is used to place waste oil, and the other is used to place waste water. The heating plate 42 can heat the waste oil and waste water placed inside the box body 1;

[0031] In addition, the interior of the waste oil treatment tank 2 can be used to treat the heated waste oil through the filling mechanism 6. When the waste oil is heated inside the tank 1, some impurities in the waste oil will be evaporated, thereby improving the purity of the waste oil. The opening of the filling hole 54 can facilitate the staff to add chemicals to the inside of the waste oil treatment tank 2. The chemicals can be selected from different materials according to actual conditions, such as aromatic amine flocculants, petroleum ether, etc.

[0032] In addition, the servo motor 52 can drive the stirring rod 53 to rotate, so that the chemical agent is fully integrated with the waste oil, thereby achieving further treatment of the waste oil. The setting of the plug rod 55 and the slot 56 can facilitate the removal and cleaning of the stirring rod 53. At the same time, the heated wastewater will turn into water vapor and flow into the inner side of the wastewater treatment box 3 through the connecting block 81, and the thermoelectric cooling plate 83 can cool the inner top of the wastewater treatment box 3, thereby treating and recycling the wastewater through condensation, reducing the discharge of wastewater.

[0033] The packing mechanism 6 includes a connecting pipe 61 fixedly connected to the inner side of the box body 1, and an oil pump 62 is provided on the outer side of the connecting pipe 61. Figure 1-Figure 5 shown.

[0034] The end of the connecting pipe 61 away from the box body 1 is fixedly connected to a hollow block 63, a filter screen 64 is provided on the inner side of the hollow block 63, a feed pipe 65 is fixedly connected to the inner side of the hollow block 63, and the end of the feed pipe 65 away from the hollow block 63 passes through the waste oil treatment box 2.

[0035] A hollow groove 131 is formed on one side of the waste oil treatment tank 2 . A transparent glass 132 is provided inside the hollow groove 131 , and the outer side of the transparent glass 132 is fixedly connected to the waste oil treatment tank 2 .

[0036] An extraction groove 112 is provided on the upper side of the mounting plate 51 , and an air outlet 111 is provided on a side of the wastewater treatment tank 3 away from the tank body 1 .

[0037] Specifically, the oil pump 62 can extract the heated waste oil from the inside of the box body 1 through the connecting pipe 61, so that the waste oil can smoothly enter the inner side of the thermoelectric cooling plate 83 and be filtered by the one-way valve 84. The filtered waste oil can then smoothly enter the inner side of the waste oil treatment tank 2, thereby achieving the smooth extraction of the waste oil into the inner side of the waste oil treatment tank 2.

[0038] In addition, after the first processing mechanism 5 processes the waste oil, the staff can separate the waste oil and the sediment through sedimentation, and the hollow tank 131 and the transparent glass 132 can facilitate the staff to observe the separation state of the waste oil.

[0039] In addition, the provision of the extraction tank 112 can facilitate the staff to extract the waste oil after precipitation and separation by extraction, thereby facilitating subsequent reuse and treatment, and the sediment can be smoothly retained on the inside of the waste oil treatment tank 2. By adding a curing agent, such as a polyurethane curing agent, to the inside of the waste oil treatment tank 2, the remaining waste oil containing a large amount of sediment can be solidified, making it convenient for subsequent incineration, power generation, reuse, etc., thereby further reducing pollution to the environment. The air outlet 111 allows the heated water vapor to be condensed while allowing the air to be smoothly discharged from the inside of the wastewater treatment tank 3, thereby reducing the situation where the pressure inside the wastewater treatment tank 3 is high, or the situation where condensation cannot be smoothly carried out due to lack of air circulation.

[0040] A cover plate 121 is provided on the upper side of the box body 1, and bolts 122 are provided between the cover plate 121 and the box body 1. Figure 1-Figure 5 shown.

[0041] A sealing rubber layer 123 is movably bonded to the lower side of the cover plate 121 , and the sealing rubber layer 123 is disposed on the upper side of the box body 1 .

[0042] A discharge pipe 101 is provided on one side of the wastewater treatment box 3 , and a valve body 102 is provided on the outer side of the discharge pipe 101 .

[0043] A guide plate 9 is fixedly connected to the inner side of the box body 1 . The upper side of the guide plate 9 is inclined. The guide plate 9 is arranged on the lower side of the connecting pipe 61 . One side of the guide plate 9 is fixedly connected to the partition plate 7 .

[0044] Specifically, the cover plate 121 can close the box body 1, thereby cooperating with the heating plate 42 to achieve rapid heating of the interior of the box body 1, and the bolts 122 can conveniently connect the cover plate 121 to the box body 1. The sealing rubber layer 123 can reduce the gap between the box body 1 and the cover plate 121. The upper side of the cover plate 121 is provided with heat dissipation holes for allowing impurities in the heated waste oil to flow smoothly out of the interior of the box body 1.

[0045] In addition, the provision of the discharge pipe 101 allows the condensed water to flow smoothly out of the interior of the wastewater treatment tank 3, and the valve body 102 can control the opening and closing of the discharge pipe 101;

[0046] In addition, the setting of the guide plate 9 allows the waste oil inside the box body 1 to flow smoothly to the lower end of the connecting pipe 61, thereby facilitating the extraction of the waste oil by the connecting pipe 61. At the same time, the box body 1, the waste oil treatment tank 2 and the wastewater treatment tank 3 can be placed on a desktop or a raised platform when in use, thereby facilitating the staff to remove the condensed water and waste oil.

[0047] An intelligent zero-discharge treatment device for scrapped motor vehicle oil and wastewater is proposed by the embodiment of the utility model, and its working principle is as follows: when in use, the device can pour the waste oil and wastewater of the scrapped motor vehicle into the two chambers of the box body 1 respectively, use bolts 122 to fix the cover plate 121 to the box body 1, and ensure that the sealing rubber layer 123 is tightly fitted to prevent heat loss and impurities from entering, start the heating plate 42, and heat the waste oil and wastewater in the box body 1. During the heating process, some impurities in the waste oil will evaporate due to the increase in temperature, and the wastewater will begin to evaporate into water vapor. The oil pump 62 extracts the heated waste oil through the connecting pipe 61 and enters the waste oil treatment box 2. The waste oil passes through the filter screen 64 in the hollow block 63 to further remove impurities, and chemical agents such as aromatic amine flocculants, petroleum ether, etc. are added to the waste oil treatment box 2 through the filling hole 54 to improve the purity of the waste oil.

[0048] The servo motor 52 drives the stirring rod 53 to rotate, so that the chemical agent and the waste oil are fully mixed. The treated waste oil is precipitated in the waste oil treatment tank 2, and the precipitate and reusable waste oil are separated. The heated water vapor flows into the wastewater treatment tank 3 through the connecting block 81. The thermoelectric cooling plate 83 cools the top of the wastewater treatment tank 3 to condense the water vapor. The condensed water is discharged through the discharge pipe 101. The precipitated and separated reusable waste oil is extracted through the extraction tank 112. For the remaining waste oil containing a large amount of sediment, a curing agent, such as a polyurethane curing agent, is added to the waste oil treatment tank 2. The solidified waste oil residue is ready for subsequent treatment, such as incineration for power generation, reuse, etc. The solidified waste oil and the residue after evaporation of water are collected and transported to professional treatment facilities for further treatment or reuse, thereby reducing the pollution of waste oil and wastewater to the environment and achieving zero emissions as much as possible.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
