Description

Technical Field

[0001] This invention relates to the field of waste oil loading and unloading technology in the catering industry, and more specifically, to a high melting point waste oil transport container loading and unloading assembly and its usage method. Background Technology

[0002] As a recyclable resource, waste cooking oil is widely used in biodiesel production, industrial lubrication, and other fields. Its transportation process mostly relies on special containers to achieve large-scale, long-distance transfer. However, high-melting-point waste cooking oil (such as animal fats and high-pour-point waste oil remaining after refining) has significant temperature sensitivity. Under normal and low-temperature conditions, it is very easy to solidify into solid or semi-solid substances. This characteristic brings serious technical challenges to oil loading and unloading operations.

[0003] Currently, most of the loading and unloading components of existing high-melting-point waste cooking oil transport containers do not have a specific heating-assisted unloading structure, or only use simple external heating methods (such as wrapping heating tape around the outer wall of the container). External heating methods have low heating efficiency and can only act on the surface of the container, unable to penetrate into the oil body. It is difficult to quickly melt the solid or semi-solid oil body into a flowable liquid state, resulting in the oil body flow being obstructed during unloading and unable to be extracted smoothly, which seriously affects the efficiency of loading and unloading operations. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the prior art and provide a high-melting-point catering waste oil transport container loading and unloading oil assembly and its usage method, which improves heating efficiency by setting a heating unit inside the oil-filled isolation bag.

[0005] To achieve the above objectives, the technical solution of the present invention is to provide a high melting point catering waste oil transport container loading and unloading oil assembly, including a container body, an isolation bag provided inside the container body, an oil outlet pipe provided in the isolation bag, a heating unit built into the bottom of the isolation bag, a hot air channel provided in the heating unit, an air inlet pipe of the heating unit connected to an air supply pipe of the isolation bag, an air outlet pipe of the heating unit connected to an exhaust pipe of the isolation bag, an oil outlet pipe located between the air supply pipe and the exhaust pipe, and both the air inlet pipe and the air outlet pipe connected to the hot air channel.

[0006] Preferably, the heating unit includes a tube body, which is an inflatable tube body. The inner cavity of the tube body forms the hot air channel. One end of the air inlet pipe is connected to the tube body, and the other end of the air inlet pipe is connected to the air delivery pipe. One end of the air outlet pipe is connected to the tube body, and the other end of the air outlet pipe is connected to the exhaust pipe. This design can reduce the space occupied by the tube body inside the isolation bag when filling oil, increase the oil capacity of the isolation bag, and help reduce transportation costs.

[0007] Preferably, the tube body, after being inflated, has a three-dimensional mesh structure. This design can improve the heat exchange efficiency between the hot fluid and the oil, thereby increasing the heating efficiency of the heating unit on the oil.

[0008] Preferably, the heating unit further includes a heating element, the two ends of which are connected to the air inlet pipe and the air outlet pipe respectively via two connecting pipes. An on / off control unit is provided on the connecting pipes, and the heating element is located on the side of the pipe body near the oil outlet pipe. This design allows the heating element to heat the oil near the oil outlet pipe, which helps to further improve the oil's heating and melting efficiency.

[0009] Preferably, the on / off control unit includes a sealing plug, a return spring, a branch pipe, and a locking sleeve. The head of the sealing plug is inserted into the end of the connecting pipe away from the heating element. One end of the return spring is fixedly connected to the sealing plug, and the other end of the return spring is fixedly connected to the inner wall of the connecting pipe. Two branch pipes are provided, one connected to the air inlet pipe and the other connected to the air outlet pipe. The rod of the sealing plug is slidably connected to the branch pipe, and the rod has a threaded section. The locking sleeve has a threaded groove that engages with the threaded section. This design allows the on / off state of the connecting pipe to be controlled by adjusting the on / off control unit.

[0010] Preferably, a first baffle and a second baffle are fixedly provided inside the branch pipe. The second baffle is located on the side of the first baffle away from the connecting pipe. The first baffle has a first through hole that is slidably connected to the rod body, and the second baffle has a second through hole for the threaded section to pass through. The outer ring of the rod body has a flange that is slidably connected to the inner wall of the branch pipe. The flange is located between the head and the threaded section, and sealing gaskets are fixedly connected to both sides of the flange. This design helps to ensure the sealing performance of the air inlet and outlet pipes.

[0011] Preferably, along the direction close to the heating element, the connecting tube is provided with a conical groove, a spring groove, and a through groove connected in sequence. The through groove communicates with the heating element, and the diameter of the through groove is smaller than the inner diameter of the spring groove. The end of the return spring away from the head is fixedly connected to the inner wall of the spring groove, and the head is inserted into the conical groove. This design helps to improve the sealing performance of the sealing plug on the connecting tube.

[0012] Preferably, the isolation bag has an opening at the top, which is sealed by a sealing element. This design facilitates the installation of the heating unit.

[0013] Preferably, the top of the container is equipped with a bag-pressing unit, which includes a fixing frame, a compression spring, and a pressing block. The fixing frame is fixedly connected to the inner top wall of the container. One end of the compression spring is connected to the inner top wall of the fixing frame, and the other end of the compression spring is fixedly connected to the pressing block. The pressing block is slidably connected to the fixing frame, and the pressing block cooperates with the inner bottom wall of the fixing frame to press and close the bag opening. This design can fix the position of the bag opening and prevent the waste oil inside the bag from flowing out of the bag opening when the waste oil sloshes during transportation.

[0014] A method for using a high-melting-point waste cooking oil transport container loading and unloading oil assembly includes the following steps: S1. Hot gas is introduced into the tube and the heating bag until the hot gas channel of the tube is connected to the inner cavity of the heating bag; S2. Adjust the on / off control unit to block the connecting pipes on both sides of the heating bag; S3. Fill the isolation bag with oil; S4. Adjust the on / off control unit in the oil unloading area to connect the heating bag with the air inlet pipe and the air outlet pipe, and continuously supply hot air to the air delivery pipe.

[0015] The beneficial effects of this invention are as follows: By using the high melting point waste oil transport container loading and unloading component and its usage method described in this invention, the waste oil in the isolation bag can be directly heated by passing hot air through the built-in heating unit, which greatly improves the heating efficiency and quickly melts the solid and semi-solid oil into a flowable liquid. In addition, the oil outlet pipe is set between the gas supply pipe and the exhaust pipe, and the hot air in the exhaust pipe and the gas supply pipe can improve the melting efficiency of the waste oil near the oil outlet pipe, thereby improving the efficiency of waste oil unloading operations.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] To better understand this invention, the following is combined with... Figures 1-11 This invention provides a detailed description of a high-melting-point waste oil transport container loading and unloading assembly and its usage method.

[0020] Example 1: like Figures 1-3As shown, a high melting point catering waste oil transport container loading and unloading assembly includes a container body 1, an isolation bag 2 inside the container body 1, an oil outlet pipe 21 in the isolation bag 2, a heating unit 3 built into the bottom of the isolation bag 2, a hot air channel 301 in the heating unit 3, an air inlet pipe 31 connected to an air supply pipe 22 in the isolation bag 2, and an air outlet pipe 32 connected to an exhaust pipe 23 in the isolation bag 2. The oil outlet pipe 21 is located between the air supply pipe 22 and the exhaust pipe 23, and both the air inlet pipe 31 and the air outlet pipe 32 are connected to the hot air channel 301.

[0021] It should be noted that the oil outlet pipe 21 is connected to the internal space of the isolation bag 2. When unloading oil, hot air is introduced into the gas supply pipe 22 through the external circulating heater (not shown in the figure). The hot air passes through the gas supply pipe 22, the inlet pipe 31, the hot air channel 301, the outlet pipe 32 and the exhaust pipe 23 in sequence and then returns to the circulating heater. The hot air heats the waste oil in the isolation bag 2 through heat conduction, thereby melting the solidified waste oil and ensuring that the waste oil can be discharged smoothly from the oil outlet pipe 21. The inlet pipe 31 can be connected to the gas supply pipe 22 through a flange connection or a heat fusion connection, and the outlet pipe 32 can also be connected to the exhaust pipe 23 through a flange connection or a heat fusion connection.

[0022] It should be emphasized that passing hot air into the heating unit 3 is only a preferred embodiment. In specific operating conditions, other hot fluids can be passed into the heating unit 3. For example, in winter or when the ambient temperature is low, hot water can be passed into the heating unit 3 to further improve the heating efficiency of the oil.

[0023] In this embodiment, a butterfly valve 51 is provided on the oil outlet pipe 21 to facilitate control of whether oil is unloaded. When the butterfly valve 51 is open, it does not obstruct the flow of waste oil in the oil outlet pipe 21, which helps to improve the efficiency of oil unloading.

[0024] By using the high melting point waste oil transport container loading and unloading assembly of the present invention, the waste oil in the isolation bag 2 can be directly heated by passing hot air through the built-in heating unit 3, which greatly improves the heating efficiency and quickly melts the solid and semi-solid oil into a flowable liquid. In addition, the oil outlet pipe 21 is set between the gas supply pipe 22 and the exhaust pipe 23. The hot air in the exhaust pipe 23 and the gas supply pipe 22 can improve the melting efficiency of the waste oil near the oil outlet pipe 21, thereby improving the efficiency of waste oil unloading operations.

[0025] Example 2: As an optimization of Example 1, such as Figure 2 , Figure 3 and Figure 6As shown, the heating unit 3 includes a tube body 33, which is an inflatable tube body 33. The inner cavity of the tube body 33 forms a hot air channel 301. One end of the air inlet pipe 31 is connected to the tube body 33, and the other end of the air inlet pipe 31 is connected to the air supply pipe 22. One end of the air outlet pipe 32 is connected to the tube body 33, and the other end of the air outlet pipe 32 is connected to the exhaust pipe 23. After the tube body 33 is inflated, it has a three-dimensional mesh structure.

[0026] It should be noted that by designing the tube 33 as an inflatable tube 33, a small amount of hot air is filled into the tube 33 during the oil filling process, ensuring that the tube 33 will not be flattened. This ensures that a circulation path can be formed after the circulating heater fills the tube 33 with air. Moreover, it can reduce the space occupied by the tube 33 in the internal space of the isolation bag 2 during oil filling, increase the oil filling capacity of the isolation bag 2, and help reduce transportation costs. The three-dimensional mesh structure of the tube 33 can increase the contact area between the tube 33 and the oil, thereby improving the heat exchange efficiency between the hot fluid and the oil in the tube 33. In addition, it can also improve the uniformity of heating the oil by the tube 33 filled with hot fluid and improve the heating efficiency of the heating unit 3 on the oil.

[0027] In this embodiment, regulating valves 52 are installed on both the gas supply pipe 22 and the exhaust pipe 23. After a small amount of hot gas is filled into the pipe body 33, the two regulating valves 52 are closed to prevent the hot gas from escaping through the gas supply pipe 22 and the exhaust pipe 23. After reaching the unloading point, before the pipe body 33 is ventilated, the two regulating valves 52 are opened so that the hot gas can flow smoothly into the pipe body 33.

[0028] Example 3: As an optimization of Example 2, such as Figure 3 and Figure 6 As shown, the heating unit 3 also includes a heating bladder 34. The two ends of the heating bladder 34 are connected to the air inlet pipe 31 and the air outlet pipe 32 respectively through two connecting pipes 341. The connecting pipes 341 are equipped with an on / off control unit. The heating bladder 34 is located on the side of the pipe body 33 near the oil outlet pipe 21.

[0029] It should be noted that during the process of passing hot fluid into the pipe 33, the hot fluid will also flow into and fill the heating bag 34. Since the heating bag 34 is closer to the oil outlet pipe 21, the heating bag 34 can further improve the heating and melting efficiency of the oil near the oil outlet pipe 21, ensuring that the container can enter the unloading process more quickly after arriving at the unloading location. Moreover, the oil will flow into the area near the heating bag 34 and be heated and melted by the heating bag 34 before flowing into the oil outlet pipe 21, which helps to reduce the risk of blocky grease flowing into the oil outlet pipe 21 and clogging the oil outlet pipe 21. Preferably, the distance between the heating bag 34 and the oil outlet pipe 21 is 2cm to 5cm.

[0030] In this embodiment, both the tube 33 and the heating bladder 34 are made of elastic material, and the tube 33 and the heating bladder 34 can deform after inflation. When the inflation rate of the tube 33 and / or the heating bladder 34 is greater than its deflation rate, the tube 33 and / or the heating bladder 34 can further expand and deform, thereby further increasing the contact area between the tube 33 and / or the heating bladder 34 and the oil, further improving the heat exchange efficiency between the hot air and the oil in the tube 33 and / or the heating bladder 34, and improving the heating efficiency of the tube 33 and / or the heating bladder 34 on the oil.

[0031] Example 4: As an optimization of Example 3, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the on / off control unit includes a sealing plug 35, a return spring 36, a branch pipe 37, and a locking sleeve 38. The head 351 of the sealing plug 35 is inserted into the end of the connecting pipe 341 away from the heating bag 34. One end of the return spring 36 is fixedly connected to the sealing plug 35, and the other end of the return spring 36 is fixedly connected to the inner wall of the connecting pipe 341. There are two branch pipes 37, one of which is connected to the air inlet pipe 31, and the other branch pipe 37 is connected to the air outlet pipe 32. The rod 352 of the sealing plug 35 is slidably connected to the branch pipe 37. The rod 352 is provided with a threaded section 3521. The locking sleeve 38 is provided with a threaded groove 381 that is threadedly engaged with the threaded section 3521.

[0032] It should be noted that the branch pipe 37 penetrates the isolation bag 2, and the connection between the branch pipe 37 and the isolation bag 2 is sealed. The rod body 352 and the head 351 are fixedly connected at the end away from the connecting pipe 341. In the natural state, under the tension of the return spring 36, the head 351 of the sealing plug 35 is inserted into the connecting pipe 341 and blocks the connecting pipe 341, so that the inner cavity of the heating bag 34 is not connected to the tube body 33. At this time, the locking sleeve 38 is fitted on the outer ring of the end of the rod body 352 that extends out of the branch pipe 37. When the sealing plug 35 is pulled away from the connecting pipe 341, the return spring 36 extends, and a gap is formed between the sealing plug 35 and the connecting pipe 341, allowing fluid to pass through. The sealing plug 35 releases the blockage of the connecting pipe 341, and the hot fluid in the pipe body 33 can flow into and fill the heating chamber 34 through the connecting pipe 341, thereby heating the oil near the oil outlet pipe 21. At the same time, the position of the sealing plug 35 can be fixed by screwing the threaded section 3521 of the rod body 352 into the locking sleeve 38, preventing the sealing plug 35 from resetting under the pull of the return spring 36. At this time, the locking sleeve 38 abuts against the end of the branch pipe 37 away from the connecting pipe 341. Before filling the isolation bag 2 with oil, first adjust the on / off control unit to not block the two connecting pipes 341 on both sides of the heating bag 34, so that some of the hot air in the pipe body 33 is forced into the heating bag 34 to ensure that there is hot air in the heating bag 34. Then adjust the on / off control unit to block the two connecting pipes 341 on both sides of the heating bag 34 to prevent the hot air in the heating bag 34 from flowing back into the pipe body 33. During the transportation of oil, the hot air in the heating bag 34 can heat and keep the oil near the oil outlet pipe 21 warm, reducing the probability of the oil near the oil outlet pipe 21 solidifying. After the container arrives at the unloading point, the oil near the oil outlet pipe 21 can be melted faster, thereby improving the unloading efficiency.

[0033] In this embodiment, a pull ring 353 is fixedly connected to the end of the rod 352 away from the head 351, so as to pull and adjust the sealing plug 35. The pull ring 353 and the locking sleeve 38 are both located outside the isolation bag 2, so as to manually adjust the sealing plug 35 and the locking sleeve 38.

[0034] Example 5: As an optimization of Example 4, such as Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a first baffle 371 and a second baffle 372 are fixedly provided inside the branch pipe 37. The second baffle 372 is located on the side of the first baffle 371 away from the connecting pipe 341. The first baffle 371 has a first through hole 3711 that is slidably connected to the rod body 352. The second baffle 372 has a second through hole 3721 through which the threaded section 3521 passes. The outer ring of the rod body 352 has a flange 3522 that is slidably connected to the inner wall of the branch pipe 37. The flange 3522 is located between the head 351 and the threaded section 3521. Sealing gaskets 39 are fixedly connected to both sides of the flange 3522.

[0035] It should be noted that the inner diameter of the first through hole 3711 is smaller than the inner diameter of the second through hole 3721. When the sealing plug 35 blocks the connecting pipe 341, the sealing gasket 39 of the flange 3522 near the head 351 fits with the first baffle 371, thereby ensuring the sealing of the air inlet pipe 31 and the air outlet pipe 32. When the sealing plug 35 does not block the connecting pipe 341, and the position of the sealing plug 35 is locked by the locking sleeve 38, the sealing gasket 39 of the flange 3522 away from the head 351 fits with the second baffle 372, thereby ensuring the sealing of the air inlet pipe 31 and the air outlet pipe 32.

[0036] Example 6: As an optimization of Example 5, such as Figure 5As shown, along the direction close to the heating element 34, the connecting pipe 341 is provided with a conical groove 3411, a spring groove 3412 and a through groove 3413 connected in sequence. The through groove 3413 is connected to the heating element 34. The diameter of the through groove 3413 is smaller than the inner diameter of the spring groove 3412. The end of the return spring 36 away from the head 351 is fixedly connected to the inner wall of the spring groove 3412. The head 351 is inserted into the conical groove 3411.

[0037] It should be noted that the head 351 is adapted to the shape of the conical groove 3411, and the opening of the conical groove 3411 at the end away from the spring groove 3412 is larger than the opening of the conical groove 3411 at the end close to the spring groove 3412. When the reset spring 36 pulls the head 351 to reset, the groove wall of the conical groove 3411 can play a guiding role, thereby ensuring the accurate reset of the sealing plug 35. In addition, the design of the conical structure is conducive to improving the sealing performance of the sealing plug 35 to the connecting pipe 341.

[0038] Example 7: As an optimization of Example 6, such as Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the isolation bag 2 has a bag opening 24 at the top, which is sealed by a sealing element 25. The top of the container has a bag pressing unit 4, which includes a fixed frame 41, a compression spring 42, and a pressing block 43. The fixed frame 41 is fixedly connected to the inner wall of the top of the container. One end of the compression spring 42 is connected to the inner wall of the top of the fixed frame 41, and the other end of the compression spring 42 is fixedly connected to the pressing block 43. The pressing block 43 is slidably connected to the fixed frame 41, and the pressing block 43 cooperates with the inner wall of the bottom of the fixed frame 41 to press the bag opening 24 closed.

[0039] It should be noted that the bag opening 24 is connected to the internal space of the isolation bag 2. The heating unit 3 can be placed into the isolation bag 2 through the bag opening 24 and then connected to the air supply pipe 22 and exhaust pipe 23 of the isolation bag 2. The sealing element 25 is an adjustable sealing structure. For example, the sealing element 25 can be set as a slider zipper structure, such as the slider zipper in a packaging bag with a slider zipper disclosed in Chinese Patent No. CN203638346U. Its specific structure is prior art and will not be described in detail here. While the bag-pressing assembly presses the bag opening 24 closed, it can also fix the position of the bag opening 24, ensuring that the bag opening 24 is above the waste oil inside the isolation bag 2, and preventing the waste oil inside the isolation bag 2 from flowing out of the bag opening 24; The fixing frame 41 is a square frame structure. The fixing frame 41 includes a top rod 411, a bottom rod 412 and two side rods 413. The top rod 411 is fixedly connected to the top inner wall of the container. The top end faces of the two side rods 413 are respectively fixedly connected to the bottom surfaces of the two ends of the top rod 411. The bottom end faces of the two side rods 413 are respectively fixedly connected to the top surfaces of the two ends of the bottom rod 412. The bottom surface of the top rod 411 is the top inner wall of the fixing tube, and the top surface of the bottom rod 412 is the bottom inner wall of the fixing frame 41. The two ends of the pressure block 43 are slidably connected to the two side rods 413. Specifically, both ends of the pressure block 43 are provided with a sliding groove 431 that is slidably connected to the side rods 413. In the natural state, under the thrust of the compression spring 42, the bottom surface of the pressure block 43 is in contact with the top surface of the bottom rod 412. After the isolation bag 2 is filled with oil, the bag opening 24 is sealed by the slider zipper structure. Then, the upper pressure block 43 is slid up, the pressure spring 42 is compressed, and a bag-pressing gap is formed between the pressure block 43 and the bottom rod 412. The bag opening 24 is passed through the bag-pressing gap. Then, the pressure block 43 is released, the pressure spring 42 extends and pushes the pressure block 43. The pressure block 43 and the bottom rod 412 together squeeze the bag opening 24, thereby sealing the bag opening 24. This helps to ensure the airtightness of the isolation bag 2. In the case of waste oil sloshing during transportation, it can prevent the waste oil in the isolation bag 2 from flowing out of the bag opening 24.

[0040] In this embodiment, a protrusion 432 is fixedly connected to the bottom of the pressure block 43, and a groove 4121 that mates with the protrusion 432 is provided on the top of the bottom rod 412. The cross-sections of the protrusion 432 and the groove 4121 are both semi-circular. The number of protrusions 432 and grooves 4121 is the same, and at least one set of each is provided. With this design, when the pressure block 43 and the bottom rod 412 press the bag opening 24, the protrusion 432 and the groove 4121 can form a mechanical engagement with the bag opening 24, which can further improve the reliability of the bag opening 24 being pressed. In the case of waste oil sloshing during transportation, the bag opening 24 in the bag pressing gap will not slip. If the bag opening 24 in the bag pressing gap slips (the slip direction is the direction in which the sealing member 25 points to the fixed frame 41 after the bag opening 24 is pressed), it may cause the pressure block 43 and the bottom rod 412 to be squeezed against the sealing member 25, thereby causing damage to the sealing member 25.

[0041] Example 8: A method for using a high-melting-point waste cooking oil transport container loading and unloading oil assembly includes the following steps: S1. Inject hot air into the tube 33 and the heating bag 34 until the hot air channel 301 of the tube 33 is connected to the inner cavity of the heating bag 34. S2. Adjust the on / off control unit to block the connecting pipes 341 on both sides of the heating bag 34; S3. Fill the isolation bag 2 with oil; S4. Adjust the on / off control unit in the unloading area to connect the heating bag 34 with the air inlet pipe 31 and the air outlet pipe 32, and continuously supply hot air to the air delivery pipe 22.

[0042] It should be noted that in S1, before inflation, pull the pull ring 353 away from the connecting pipe 341 and screw the threaded section 3521 into the threaded groove 381 of the locking sleeve 38, and open the regulating valve 52 on the air inlet pipe 31.
