Description

Technical Field

[0001] The utility model relates to the field of waste oil recovery devices, in particular to a waste oil recovery and transportation device. Background Art

[0002] Biodiesel refers to fatty acid methyl esters or ethyl esters formed by esterification of vegetable oils (such as rapeseed oil, soybean oil, peanut oil, corn oil, cottonseed oil, etc.), animal oils (such as fish oil, lard, tallow, sheep oil, etc.), waste oils or microbial oils with methanol or ethanol. Vegetable oils and animal fats with fatty acid glycerides (i.e. triglycerides) of certain structural symbols are usually used as raw materials for biodiesel.

[0003] The process of recycling waste oil and producing biodiesel is an environmentally friendly technology that converts waste into useful energy. Waste oil usually comes from the catering service industry, food processing, household kitchen waste, etc. After collection, it needs to be processed initially, such as heating, filtering to remove scum, and separating oil and water to obtain crude oil. Then, it is prepared through ester exchange reaction to convert triglycerides in waste oil into fatty acid methyl esters, which not only helps to reduce environmental pollution, but also realizes the recycling of resources.

[0004] The existing waste oil collection and transportation device is generally a container or a container. After the waste oil fills the container or container, the container or container is sealed with a sealing cover and then transported. However, in the process of collecting waste oil in the container or container, before the sealing cover is closed, the movement of the container or container will cause the waste oil inside to vibrate, thereby causing the waste oil to splash outward. In particular, the higher the liquid level of the waste oil inside, the more waste oil will splash outward. If the sealing cover is temporarily closed when the container or container is not full, and the container or container is moved and then repeatedly opened until the container or container is filled with waste oil and then completely sealed, in the process of temporarily opening the sealing cover, the splashed waste oil will also slide along the inner wall of the sealing cover, and repeated closing increases the complexity of the operation. Moreover, when the waste oil needs to be sealed with a sealing cover, the packaging conditions at the waste oil collection site are difficult to achieve a completely sealed effect, and it is also easy to leak during transportation.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0006] The utility model aims to provide a waste oil recovery and transportation device, which solves the problem in the prior art that the waste oil is easily splashed out during the movement of the waste oil collection box by opening a through hole on the cover body, arranging a feed hopper higher than the containing box body on the through hole, and movably hinged a hopper cover on the upper end of the feed hopper.

[0007] The utility model embodiment is realized by the following technical scheme: The utility model embodiment provides a waste oil recovery and transportation device, comprising a container body with an upper opening, a cover body sealed on the upper end of the container body, a through hole is provided on the cover body, a feed hopper is detachably mounted on the through hole, the bottom end of the feed hopper is connected to the through hole, the upper end of the feed hopper is open, and a hopper cover is movably hinged on the upper end, and the hopper cover is arranged to rotate to open or close the opening of the feed hopper;

[0008] The upper end surface of the feeding hopper is higher than the upper end surface of the containing box.

[0009] Preferably, a plurality of rollers are provided at the bottom of the containing box.

[0010] Preferably, the cross-sectional size of the cavity of the hopper gradually increases from bottom to top.

[0011] Preferably, the cross section of the hopper is circular or quadrilateral.

[0012] Preferably, the height of the upper end surface of the opening on one side where the feeding hopper is hinged to the hopper cover gradually decreases toward the end surface on the opposite side.

[0013] Preferably, the bucket cover is in the shape of an upwardly convex curved surface.

[0014] Preferably, a filter screen is provided at the bottom of the hopper, and the size of the filter screen is adapted to the size of the through hole.

[0015] Preferably, a heightened enclosure plate is provided on the top outer edge of the cover body.

[0016] Preferably, a groove is provided on the periphery of the through hole, a mounting plate is extended on the periphery of the side surface of the bottom end of the feed hopper, a plurality of first bolt holes are provided on the groove, a plurality of second bolt holes are provided on the mounting plate, each first bolt hole corresponds to a second bolt hole, and each pair of corresponding first bolt holes and second bolt holes can be locked by a screw at the same time;

[0017] When the hopper is mounted on the through hole, there is a gap between the outer periphery of the mounting plate and the inner side wall of the groove, and at this time the height of the mounting plate is lower than the height of the cover body.

[0018] Preferably, two hanging parts are symmetrically arranged on both sides of the containing box, and the hanging parts are hinged to the containing box.

[0019] Compared with the prior art, the embodiments of the present invention have the following advantages and beneficial effects:

[0020] 1. The utility model provides a waste oil recovery and transportation device, wherein a cover body is sealed and covered on the upper end of a receiving box body, and the cover body and the receiving box body can be detachably connected or can be sealed and integrated. A through hole is provided on the cover body, and a feed hopper is sealed and installed at the through hole. During the waste oil collection process, the feed hopper is fed through the feed hopper without opening the cover body. At the same time, a bucket cover is movably hinged at the upper end of the feed hopper, and the bucket cover can always cover the upper end of the feed hopper without the action of external force. When the upper end of the feed hopper needs to be opened for feeding, force only needs to be applied to the bucket cover to rotate it around the hinge to open it. When the hopper is opened and the feeding is suspended and the containing box is moved, the hopper cover will return to the state of covering the upper end opening of the hopper under the action of the elastic force at the hinge and its own gravity, and automatically achieve sealing to prevent the waste oil inside the containing box from splashing. Since the upper end surface of the hopper is set to be higher than the upper end surface of the containing box, the height difference between the upper end surface of the waste oil liquid inside the containing box and the free end of the hopper opening can be increased, thereby reducing the amount of waste oil splashing. At the same time, it can also avoid the possibility of the waste oil inside pouring out due to the tilting of the containing box when the waste oil liquid level in the containing box is too high.

[0021] 2. Setting the feed hopper to a structure in which the cross-sectional size of the cavity gradually increases from bottom to top can improve the ease of feeding at the upper end of the feed hopper. Increasing the size of the upper end opening can reduce the amount of leakage from the side during feeding. Combined with the filter screen at the bottom of the feed hopper for filtering large particles of impurities, large particles of impurities can be separated into the feed hopper, reducing the impurities of the waste oil added to the containing box, avoiding the blockage of the through holes, and improving the efficiency of the containing box in collecting and transporting waste oil. Impurities that have not entered the containing box will be concentrated in the feed hopper and gradually accumulate in the feed hopper, making it easy to remove.

[0022] 3. A heightened enclosure is provided on the outer edge of the top of the cover body. The heightened enclosure and the upper end of the cover body can form a accommodating space, which can receive a small amount of waste oil spilled when the hopper recovers waste oil. Combined with the grooves on the periphery of the through hole, because the height of the grooves is lower than the upper end surface of the cover body, a small amount of waste oil on the upper end surface of the cover body can enter the grooves for temporary storage. When the hopper is subsequently disassembled, it can be connected with the waste oil in the accommodating box along the through hole, and even enter the accommodating box, thereby avoiding waste oil.

[0023] 4. The mounting plate is connected to the groove with bolts, which not only ensures the stability and sealing of the connection, but also improves the flexibility of disassembly and installation of the entire device. The mounting plate is set to be lower than the height of the cover body, and a gap is allowed between the outer periphery of the mounting plate and the inner wall of the groove, thereby increasing the space size of the groove to accommodate waste oil.

[0024] In general, the waste oil recovery and transportation device provided by the embodiment of the utility model has a through hole in the cover body, and a feed hopper higher than the containing box body is arranged on the through hole, and a bucket cover is movably hinged at the upper end of the feed hopper. During the collection and transportation process, there is no need to repeatedly open or close the sealing cover, so as to achieve the purpose of reducing splashing out of the containing box body and simplifying the operation.

[0036] Example

[0037] like Figure 1-2 As shown, an embodiment of the utility model provides a waste oil recovery and transportation device, including a containing box body 1 with an upper opening, which is used to store the collected waste oil. The upper end of the containing box body 1 is sealed with a cover body 2 to prevent the waste oil from leaking or volatilizing. The cover body 2 and the containing box body 1 can be detachably connected or can be integrally arranged. When the cover body 2 and the containing box body 1 are detachably connected, the cover body 2 can be opened to clean the inner cavity of the containing box body 1. Even when the cover body 2 or part of the structure on the cover body 2 is damaged, the cover body 2 can be replaced separately, which is not limited here. As a preferred embodiment of the present utility model, the cover body 2 is detachably connected to the containing box body 1, and a through hole 3 is provided on the cover body 2. The through hole 3 is a channel for waste oil to enter the containing box body 1. A hopper 4 is detachably installed on the through hole 3. The bottom end of the hopper 4 is connected to the through hole 3, and the upper end of the hopper 4 is open to ensure that the waste oil can smoothly flow into the containing box body 1 through the hopper 4. A hopper cover 5 is movably hinged at the upper end of the hopper 4, and the hopper cover 5 is configured to rotate to open or close the opening of the hopper 4, thereby controlling the closed state of the upper end opening of the hopper 4; the upper end surface of the hopper 4 is higher than the upper end surface of the containing box body 1, which can not only prevent the waste oil from overflowing, but also increase the height difference between the upper end surface of the waste oil liquid inside the containing box body 1 and the free end of the opening of the hopper 4, thereby reducing the amount of waste oil splashing.

[0038] It should be noted that the hinged structure between the bucket cover 5 and the feed hopper 4 can be realized by adopting the existing elastic joint structure, that is, when waste oil is not added to the feed hopper 4, the bucket cover 5 always remains covered with the upper end opening of the feed hopper 4 under the action of the hinged structure and its own gravity. When waste oil needs to be added, the operator only needs to apply force to the bucket cover 5 to make the bucket cover 5 rotate around the hinged structure, so that the bucket cover 5 is separated from the upper end opening of the feed hopper 4. The whole structure is easy to operate. When collecting waste oil, there is no need to open the cover body 2, and there is no need to install the cover body 2 on the collection site. It can be achieved only through the cooperation of the feed hopper 4 and the bucket cover 5. At the same time, in the process of moving the containing box 1, the bucket cover 5 can always remain sealed and covered with the upper end opening of the feed hopper 4, which can avoid the waste oil splashing out due to the vibration during the movement of the containing box 1. In order to facilitate the operator to observe whether the waste oil collected in the storage box 1 is full, the feed hopper 4 can be set to be transparent, that is, when the waste oil liquid level is at the bottom of the feed hopper 4, the waste oil is stopped from being added to the storage box 1. Of course, a liquid level observation device can also be directly set on the storage box 1, which is not limited here. Preferably, the cover can be set to an upwardly convex arc surface, so that the waste oil splashed from the feed hopper 4 to the inner side of the bucket cover 5 can be quickly diverted into the storage box 1. In order to increase the sealing between the bucket cover 5 and the feed hopper 4, mutually engaging slots and protrusions can be set at the cover of the bucket cover 5 and the feed hopper 4.

[0039] In order to facilitate the transportation and movement of the containing box 1, a plurality of rollers 6 can be arranged at the bottom of the containing box 1. For example, the containing box 1 is in the shape of a rectangle, and a roller 6 is respectively arranged at the four right angles of the bottom of the containing box 1. The rollers 6 make the whole device easy to move, especially after loading the waste oil, which can reduce the labor intensity of manual handling and reduce the direct friction between the bottom of the box and the ground, thereby extending the service life of the box. The rollers 6 are arranged at the four right angles of the bottom of the box to ensure the balance of the device during movement and reduce the instability caused by the shift of the center of gravity. Of course, in other embodiments, the shape of the containing box 1 is not restricted, and the number and setting position of the rollers 6 are not restricted here, as long as the purpose of rolling movement stability can be achieved.

[0040] Furthermore, the cross-sectional size of the cavity of the hopper 4 gradually increases from bottom to top, and the larger opening makes it easier to add waste oil into the hopper 4, while reducing overflow caused by improper operation. As the cross-sectional size of the cavity gradually increases, the volume of the hopper 4 also increases, further reducing the splashing of waste oil caused by the movement of the container 1, and at the same time, the field of view of the hopper 4 to the container 1 can be increased, so that the addition of waste oil can be observed at any time. For example, Figure 3 and Figure 4As shown, the cross section of the feed hopper 4 is circular or quadrilateral. The circular cross section is conducive to fluid dynamics, reduces turbulence, makes the waste oil flow more smoothly, and is easy to clean. There are no corners and gaps, which reduces waste oil residue and cleaning dead corners. Preferably, as shown in FIG. Figure 3 As shown, the height of the upper end surface of the opening on one side of the feed hopper 4 and the hopper cover 5 is gradually reduced toward the end surface on the opposite side. This structure can further increase the size of the upper end opening of the feed hopper 4, further prevent leakage of waste oil during the addition process, and at the same time help control the flow speed of the waste oil so that it can flow into the containing box 1 more smoothly.

[0041] In order to improve the efficiency of the housing 1 in recycling and transporting waste oil raw materials, in the embodiment of the utility model, a filter screen 7 is provided at the bottom of the feed hopper 4. The size of the filter screen 7 is adapted to the size of the through hole 3. The filter screen 7 can effectively separate solid impurities in the waste oil and improve the purity of the waste oil. The size of the filter screen 7 is adapted to the through hole 3 to ensure that the waste oil can smoothly pass through the filter screen 7 into the housing without affecting the inflow efficiency of the waste oil. The filtering process can improve the recovery quality of the waste oil and provide higher quality raw materials for subsequent reuse or treatment. The solid impurities that have not passed through the filter screen 7 will gradually accumulate in the feed hopper 4 and can be cleaned at any time. If the blockage is serious, the feed hopper 4 can be disassembled and the filter screen 7 can be thoroughly cleaned or replaced.

[0042] Furthermore, a heightened enclosure 12 is provided on the top outer edge of the cover body 2. The heightened enclosure 12 can prevent overflow due to improper operation or excessive waste oil during the waste oil pouring process, because a accommodating cavity can be formed between the heightened enclosure 12 and the top of the cover body 2, which can maliciously collect a small amount of waste oil. As a preferred embodiment of the utility model, a groove 8 is provided on the periphery of the through hole 3. The groove 8 not only provides space for the installation of the hopper 4, but also can collect a small amount of waste oil. A mounting plate 9 is extended on the periphery of the side surface of the bottom end of the hopper 4 to cooperate with the groove 8. A plurality of first bolt holes 10 are provided on the groove 8, and a plurality of second bolt holes 11 are provided on the mounting plate 9. Each first bolt hole 10 corresponds to a second bolt hole 11, and each pair of corresponding first bolt holes 10 and second bolt holes 11 can be locked by a screw 13 at the same time; that is, the first bolt hole 10 on the groove 8 corresponds to the second bolt hole 11 on the mounting plate 9 one by one, ensuring precise installation. The screws 13 pass through the corresponding bolt holes to fix the hopper 4 and the through hole 3. When the hopper 4 is installed on the through hole 3, there is a gap 14 between the outer periphery of the mounting plate 9 and the inner wall of the groove 8, allowing a certain degree of adjustment and movement, thereby improving the flexibility of installation. At this time, the height of the mounting plate 9 is lower than the height of the cover body 2, thereby ensuring that the groove 8 has a certain oil holding space. When the hopper 4 is disassembled, the waste oil in the groove 8 can directly enter the containing box body 1 through the through hole 3. At the same time, the waste oil on the top of the cover body 2 can also be introduced into the containing box body 1 to avoid waste oil. Preferably, the cover body 2 of the utility model is a downwardly concave structure, and the through hole 3 is a low-lying area.

[0043] Exemplarily, the groove 8 has a rectangular outline, the outer outline of the mounting plate 9 is also a rectangle, four first bolt holes 10 are provided, and correspond to the second bolt holes 11 provided at the four corner positions of the edge of the mounting plate 9. Of course, in order to improve the sealing of the connection between the mounting plate 9 and the groove 8, a rubber pad can be provided at the connection of the screw 13. Since there is a gap 14 between the inner side wall of the groove 8 and the outer periphery of the mounting plate 9 in the embodiment of the utility model, the contact area between the bottom wall of the groove 8 and the mounting plate 9 is guaranteed, and the sealing of the joint between the hopper 4 and the through hole 3 can also be improved. Of course, two lifting parts 15 can also be symmetrically arranged on both sides of the containing box 1, and the lifting parts 15 are hinged to the containing box 1. The lifting parts 15 allow the entire device to be lifted and transported by equipment such as a crane or a hoist, thereby improving the efficiency and safety of transportation, and improving the diversity and practicality of the moving mode of the containing box 1 of the utility model. The hinged design allows the lifting parts 15 to be folded or retracted when not in use, reducing the occupied space and also facilitating the operator to perform daily operations. The symmetrical lifting parts 15 on both sides provide balanced lifting points to ensure the stability of the device during the lifting process.

[0044] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the utility model omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the utility model.
