Description

Technical Field

[0001] This invention relates to the field of laboratory natural bitumen dehydration processing technology, and more specifically, to an experimental device specifically designed for the dehydration and drying of natural bitumen. Background Technology

[0002] Natural asphalt, also known as geoasphalt or mineral asphalt, is a product of petroleum transformation. When crude oil seeps into the ground, its lighter components evaporate and are then oxidized by oxygen in the air under sunlight, subsequently polymerizing to form asphalt minerals. It mainly consists of asphaltenes, resins, and other gums, as well as small amounts of other mineral impurities, including metallic and non-metallic compounds. This type of asphalt has mostly undergone natural evaporation and oxidation and generally does not contain any toxins. Natural asphalt is a special heat-sensitive material; after dehydration and drying, it produces a certain amount of oil-water mixture and alkane gases.

[0003] When carrying out dehydration and drying operations on natural asphalt, it is necessary to use corresponding natural asphalt drying and dehydration equipment.

[0004] Based on the above:

[0005] ① The drying and heating equipment currently used on the market is bulky and mostly uses propane, natural gas or liquefied gas for heating. In actual heating, the temperature is not easy to control, and natural asphalt will produce flammable and explosive gases such as alkanes after heating, which poses certain safety hazards. Therefore, it is difficult to adapt to the laboratory environment.

[0006] ② When natural asphalt is heated, the resulting oil-water mixture is prone to backflow. When the backflowing oil-water mixture comes into contact with the material, it is very easy to form lumps, which ultimately affects the quality of the dehydrated natural asphalt.

[0007] Therefore, in view of this, we will study and improve the existing structure to provide an experimental device specifically for the dehydration and drying of natural asphalt, in order to achieve a more practical purpose. Summary of the Invention

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0056] Example 1:

[0057] Please see Figure 1-8 An experimental device specifically designed for the dehydration and drying of natural asphalt includes a support platform 1, on which a condensation box 2, a storage tank 3, a heating chamber 4, and a control table 5 are fixed. One of the output ports of the condensation box 2 is connected to the storage tank 3 through a pipeline. A buffer tank 6 is provided between the condensation box 2 and the heating chamber 4 and is connected by a pipeline.

[0058] When the equipment is used to dehydrate and dry natural asphalt, it is controlled by the control panel 5. First, the natural asphalt to be dehydrated is put into the heating chamber 4. Using the heating effect, the oil, water and gas are discharged into the buffer tank 6. The water vapor flows into the condenser 2 to condense, while the oil and water mixture is solidified in the buffer tank 6 and discharged from the buffer tank 6. The condensed water vapor flows into the storage tank 3 for storage for subsequent use. In this way, the process of dehydrating and drying natural asphalt can be completed, and the oil, water and gas generated during dehydration can be effectively treated.

[0059] Specifically, the bearing platform 1 is a steel plate structure with a thickness of 5mm, and rollers 101 and horizontal adjustment threaded rods 102 are fixedly installed around the bottom of the bearing platform 1. A level 103 is fixedly installed at the diagonal corners of the upper surface of the bearing platform 1.

[0060] The steel plate structure has a good load-bearing capacity. The rollers 101 are used to move the bearing platform 1. The horizontal adjusting threaded rod 102 and the level 103 are used together to adjust the levelness of the upper surface of the bearing platform 1, ensuring that the equipment on the bearing platform 1 is on the same horizontal plane.

[0061] Example 2:

[0062] Based on the above embodiment 1, further description is provided.

[0063] Please see Figure 3 The condenser box 2 is fixed to the top side of the support platform 1. A water inlet 201 is fixedly provided at one end of the side of the condenser box 2, and a condensate outlet 202 is fixedly provided at the other end of the side of the condenser box 2. The other outlet of the condenser box 2 is connected to the buffer tank 6 through a pipeline. The outlets of the water inlet 201 and the condensate outlet 202 are both facing downwards.

[0064] Please see Figure 4 and Figure 5 The storage tank 3 is fixed at one end of the top side of the support platform 1. One of the outlets of the storage tank 3 is the non-condensable steam outlet 301, and a water storage tank 302 is connected to the non-condensable steam outlet 301 through a pipeline. One of the outlets of the storage tank 3 is the discharge outlet 303. A pressure gauge 304 is fixedly installed on the top of the storage tank 3.

[0065] Specifically, a vent 3021 is fixedly installed on the top of the water storage tank 302, and a vent pipe 3022 is fixedly connected to the vent 3021.

[0066] When water is introduced into the water storage tank 302, the air in the water storage tank 302 is discharged through the vent 3021 and the vent pipe 3022, so as to provide space for water to enter the water storage tank 302.

[0067] A water storage outlet 3023 is fixedly installed on the side of the water storage tank 302, and the outlet of the water storage outlet 3023 faces downward.

[0068] Excess water in the water storage tank 302 can be taken out through the water outlet 3023, which facilitates the reuse of the water after the natural asphalt has been dehydrated.

[0069] Specifically, a transparent glass plate structure is provided in the middle of the side of the storage tank 3, and a scale line 305 is fixedly provided on the transparent glass plate structure.

[0070] The water level in the storage tank 3 can be observed more intuitively using the scale line 305, which makes it easier to determine the subsequent operation of the storage tank 3 based on the water level.

[0071] Please see Figure 6 The heating chamber 4 is fixed at the top and near the middle of the bearing platform 1. One end of the central shaft of the heating chamber 4 is fixedly connected to a support shaft 401. The side of the support shaft 401 is provided with a right-facing support base 402 with bearings. The other end of the central shaft of the heating chamber 4 is fixedly provided with a guide pipe 403. The side of the guide pipe 403 is provided with a left-facing support base 404 with bearings. The side of the heating chamber 4 is fixedly provided with a first thermometer 405.

[0072] Specifically, an electric heating sleeve 406 is provided on the outer side near the heating chamber 4, and the electric heating sleeve 406 is fixed to the top of the support platform 1;

[0073] A first data power line 4061 is fixedly installed on the outer side of the electric heating jacket 406, and is connected to the control panel 5 for signal transmission through the first data power line 4061.

[0074] The gap between the electric heating jacket 406 and the heating chamber 4 is 5mm. During the use of the heating chamber 4, the heating chamber 4 is in a continuous rotating state, while the electric heating jacket 406 is always in a fixed state. When heating, the control panel 5 controls the electric heating jacket 406 to heat up through the first data power line 4061, which facilitates continuous and uniform heating of the heating chamber 4.

[0075] Specifically, a sealing joint 4031 is provided on the feed pipe 403, located between the heating chamber 4 and the left-hand support base 404 with bearing, and a sealing bearing 4032 is provided on the feed pipe 403, located between the buffer tank 6 and the left-hand support base 404 with bearing.

[0076] The sealing performance between the feed pipe 403 and the guide pipe 601 is enhanced by using a sealing union 4031 and a sealing bearing 4032.

[0077] Specifically, a large gear ring 4033 is fixedly installed on the feed pipe 403, between the sealed bearing 4032 and the left-side support base 404 with bearing. A chain 4034 is meshed on the large gear ring 4033, and a small gear ring 4035 is driven through the chain 4034. An adjustable speed small motor 4036 is fixedly installed on the bearing platform 1. The output end of the adjustable speed small motor 4036 is driven through the small gear ring 4035 via a coupling.

[0078] A second data power line 4037 is connected between the adjustable speed small motor 4036 and the control panel 5.

[0079] The control console 5 controls the rotation of the adjustable speed small motor 4036 through the second data power line 4037. At this time, a transmission relationship is formed between the small gear ring 4035, the chain 4034 and the large gear ring 4033, which can ultimately control the rotation of the guide tube 403.

[0080] During transmission, the transmission ratio between the small gear ring 4035 and the large gear ring 4033 is 1:N, and N<1, which means that the small gear ring 4035 rotates many times while the large gear ring 4033 rotates once. This allows the large gear ring 4033 and the guide tube 403 to rotate continuously and uniformly at a low speed.

[0081] Please see Figure 7 The control panel 5 is fixed at one end of the top side of the support platform 1. The operating part of the control panel 5 includes a temperature adjustment knob 501 with a protective cover and a speed adjustment knob 502 with a protective cover. The temperature adjustment knob 501 with a protective cover and the speed adjustment knob 502 with a protective cover are respectively set on the top side of the control panel 5. The display part of the control panel 5 includes an electric heating mantle temperature display 503. The electric heating mantle temperature display 503 is set in the middle of one side of the top of the control panel 5. The main power cord 504 is fixedly installed on the side of the control panel 5.

[0082] Please see Figure 8 The buffer tank 6 has a connecting pipe 601 on its side and is fixed to the feed pipe 403 through the connecting pipe 601. A second thermometer 602 is fixedly installed on the connecting pipe 601.

[0083] Specifically, a U-shaped pipe 603 is provided between the top of the buffer tank 6 and the side of the condenser 2. A slag discharge pipe 604 is fixedly provided at the end of the buffer tank 6 away from the feed pipe 403, and the outlet of the slag discharge pipe 604 faces downward.

[0084] Using the U-shaped pipe 603, the green grapes are discharged from the buffer tank 6 to the condenser 2. Then, most of the oil-water mixture in the buffer tank 6 can be discharged through the slag discharge pipe 604.

[0085] Specifically, the bottom of the buffer tank 6 is fixedly equipped with a slag discharge port 605 with a valve, and the outlet of the slag discharge port 605 faces downward.

[0086] The slag discharge port 605 with a valve can be used to discharge the oil-water mixture that is difficult to remove from the buffer tank 6, thus preventing solid slag from clogging the buffer tank 6.

[0087] Example 3:

[0088] Further description is provided based on the above embodiments 1 and 2.

[0089] Please see Figure 1-8 When the entire device is put into use:

[0090] First, the roller 101 is used to move the bearing platform 1. The horizontal adjusting threaded rod 102 and the level 103 are used together to adjust the levelness of the upper surface of the bearing platform 1, ensuring that the equipment on the bearing platform 1 is on the same horizontal plane.

[0091] During operation, the entire equipment is uniformly controlled by the control panel 5, which is powered by the main power line 504. By rotating the temperature adjustment knob 501 with a protective cover and the speed adjustment knob 502 with a protective cover, the temperature value of the corresponding electric heating jacket 406 and the speed value of the adjustable speed small motor 4036 are controlled, and the heating result is displayed on the electric heating jacket temperature display table 503.

[0092] Inside the heating chamber 4, the natural asphalt to be dried and dehydrated is placed inside. Using the right-hand support base 402 with bearings and the left-hand support base 404 with bearings, the support shaft 401, the heating chamber 4, and the guide tube 403 are able to rotate freely and synchronously. Then, the control console 5 controls the rotation speed of the adjustable speed small motor 4036 through the second data power line 4037. At this time, a transmission relationship is formed between the small gear ring 4035, the chain 4034, and the large gear ring 4033, which ultimately controls the rotation of the guide tube 403. At the same time, the control console 5 controls the electric heating jacket 406 to heat up through the first data power line 4061, which facilitates continuous and uniform heating of the heating chamber 4.

[0093] During the heating process, the water and oil-water mixture extracted from the natural asphalt enters the buffer tank 6 through the feed pipe 403 and the connecting pipe 601. Then, through the U-shaped pipe 603, the buffer tank 6 discharges gas into the condensation box 2. Through the slag discharge pipe 604, most of the oil-water mixture in the buffer tank 6 can be discharged. Through the slag discharge port 605 with a valve, the oil-water mixture that is difficult to remove from the inside of the buffer tank 6 can be discharged, avoiding solid slag from clogging the buffer tank 6.

[0094] After the gas reaches the condenser 2, condensate is introduced through the inlet 201 and discharged through the outlet 202, thus realizing the condensation of the gas.

[0095] The condensed water flows into storage tank 3. Non-condensable vapor and some liquid in storage tank 3 are discharged from non-condensable vapor outlet 301 into water storage tank 302. Gas is discharged through exhaust port 3021 and exhaust pipe 3022, and water is discharged through water outlet 3023. The remaining liquid in storage tank 3 is discharged through outlet 303. When water is stored in and discharged from storage tank 3, the water volume inside storage tank 3 is determined according to pressure gauge 304 and scale line 305 to facilitate timely removal of water and ensure that there is sufficient water storage space inside storage tank 3.

[0096] This allows for the dehydration and drying of natural asphalt in a single process, while also enabling the condensation and recovery of gases and the treatment of oil-water mixtures.

[0097] First, the natural asphalt to be dehydrated is put into the heating chamber 4. Utilizing the heating effect, the oil, water and vapor are discharged into the buffer tank 6. The water vapor flows into the condensation box 2 for condensation, while the oil and water mixture solidifies in the buffer tank 6 and is discharged from the buffer tank 6. The condensed water vapor flows into the storage tank 3 for storage, so as to facilitate subsequent use. In this way, the process of dehydrating and drying natural asphalt can be completed, and the oil, water and vapor generated during dehydration can be effectively treated.

[0098] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
