Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to an asphalt oil extraction device. Background Art

[0002] An asphalt extractor (also called an asphalt separator or petroleum asphalt separator) is a device used to separate petroleum asphalt from a mixture. It is widely used in asphalt mixture production, especially in road construction and maintenance. The function of an asphalt extractor is to separate asphalt from petroleum so that it can be used to prepare road asphalt mixture. As asphalt has the characteristics of high viscosity and insolubility in water, an extractor is needed to separate it from petroleum. This can make the asphalt purer and more stable, thereby improving the quality and durability of road materials. However, the current asphalt separation devices all heat the entire device, which takes a long time and cannot be used for continuous production, and the use effect is not ideal. Utility Model Content

[0003] The utility model provides an asphalt oil extraction device, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] An asphalt oil extraction device comprises an outer tube, a feed pipe, a low liquid level discharge pipe and a liquid extraction pipe, wherein a heating block is provided at the inner bottom end of the outer tube, a guide groove is provided on the heating block, a liquid extraction pipe is inserted into the outer tube, a low liquid level discharge pipe is provided at one end of the liquid extraction pipe located outside the outer tube, and a feed pipe is mounted at the top end of the outer tube.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a fixing frame is provided on the outer side of the feed pipe, and the feed pipe is fixed to the opening of the outer pipe through the fixing frame.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] Enhanced stability: The fixing frame provides additional support and fixation to ensure that the feed pipe remains stable during use. This design can effectively reduce the instability caused by shaking or loosening of the feed pipe during operation, thereby improving the reliability and safety of the equipment.

[0010] Avoid displacement: Asphalt oil extraction equipment usually works in a high temperature and high pressure environment. If the feed pipe is not well fixed, it may be displaced due to thermal expansion and contraction or vibration. The design of the fixing frame can effectively avoid the displacement of the feed pipe during operation, ensuring the continuity and stability of the production process.

[0011] Reduced failure rate: The feed pipe holder can reduce equipment failures caused by external factors. For example, if the feed pipe moves due to vibration or temperature changes, it may cause damage or leakage to the connecting pipe. The use of the holder can effectively reduce the occurrence of this situation, reduce the frequency of maintenance and downtime, and improve production efficiency.

[0012] Convenient operation: The design of the fixed frame makes the feed pipe more stable, which also makes it easier for the operator to operate. The operator does not need to frequently adjust or repair the position of the feed pipe, saving maintenance and adjustment time and improving work efficiency.

[0013] Extended service life: Through the stability of the fixed frame, the wear of the feed pipe and connecting parts can be reduced, and the service life of the device can be extended. This has a positive impact on reducing the maintenance cost of the equipment and improving the return on investment.

[0014] Furthermore, the end of the liquid extraction pipe is located at the heating block, and the heating block is locally heated to separate the asphalt and oil according to different melting points, and then the separated asphalt or oil is sucked out of the outer tube through the liquid extraction pipe.

[0015] The beneficial effects of adopting the above further scheme are:

[0016] Precise control of the separation process: By designing the end of the liquid extraction tube at the heating block, it can ensure that the asphalt and oil are fully separated under the action of local heating. This local heating method can accurately control the temperature and ensure that the asphalt and oil are effectively separated according to their different melting points, thereby improving the efficiency and quality of separation.

[0017] Improve separation efficiency: Through local heating of the heating block, the separation speed of asphalt and oil can be accelerated, thereby shortening the separation process time. This not only improves production efficiency, but also reduces production costs.

[0018] Reduced energy consumption: Compared with overall heating, local heating can effectively reduce energy consumption. By concentrating the heating in the separation area, it can reduce the overall heating energy consumption while ensuring the separation effect, saving energy costs.

[0019] Simplified operation process: The extraction pipe is directly placed on the heating block, making the separation and extraction process more simplified and integrated. Operators do not need additional steps or equipment to separate asphalt and oil, but directly extract the separated products through the extraction pipe, which simplifies the operation process and improves the convenience of operation.

[0020] Reduced contamination risk: Local heating and direct extraction reduce the contact and possible contamination risk of bitumen and oil during transfer. This helps maintain the purity and quality of bitumen and oil, improving the quality of the final product.

[0021] Furthermore, the feed pipe guides the raw materials during feeding.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] Accurate feeding: The guiding function can ensure that the raw materials accurately enter the working area of ​​the asphalt oil extraction device, avoiding the waste and overflow of raw materials, and ensuring the accuracy and stability of the production process.

[0024] Reduced operational difficulty: The guide function makes it easier for the operator to control the flow of raw materials when loading, reducing the complexity and technical difficulty of the operation. This helps reduce the risk of operational errors and improves work efficiency.

[0025] Avoid equipment damage: By directing the flow of raw materials, raw materials can be prevented from entering the non-working area inside the device, reducing the possibility of equipment damage due to mishandling of raw materials. This helps to extend the service life of the equipment and reduce maintenance costs.

[0026] Improve production efficiency: Accurately guiding the raw materials can ensure that the device can work continuously and efficiently, avoiding pauses and delays in the raw material feeding process, thereby improving production efficiency and reducing production costs.

[0027] Guarantee product quality: Accurately guiding raw materials can ensure that they are correctly delivered to the separation area, ensuring the normal progress of the separation process. This helps to ensure the quality and stability of the product and improve the quality and market competitiveness of the final product.

[0028] The beneficial effects of the utility model are:

[0029] Advantages of local heating: Traditional heating methods usually heat the entire device, which consumes a lot of energy and requires a long heating time. However, this device adopts a local heating method. Through the design of the heating block, the heating focus can be concentrated on the separation area of ​​asphalt and oil, thereby greatly shortening the heating time and reducing the heating cost. This local heating method can more effectively improve energy utilization and reduce production costs.

[0030] High separation efficiency: The separation of asphalt and oil is usually achieved by heating because they have different melting points. Through local heating of the heating block, the temperature can be controlled more accurately to ensure the maximum separation efficiency of asphalt and oil. This separation method can effectively remove the bottom layer of asphalt, thereby improving the purity and quality of the oil.

[0031] Convenient operation: The device is designed with components such as feed pipes and liquid extraction pipes, which make it easier for operators to guide and extract raw materials. The setting of the feed pipe can ensure that the raw materials are correctly guided to the separation area, while the design of the liquid extraction pipe can easily extract the separated products. This operation design simplifies the operation process, reduces the workload of operators, and reduces the possibility of operating errors.

[0032] Stable structure: The device is designed with structural stability and safety in mind. By installing a feed pipe on the top of the outer tube and fixing the feed pipe to the opening of the outer tube through a fixing frame, the structural stability of the device during operation is ensured, reducing possible failures and damages caused by loose structure.

[0033] Increased production: The device uses a layered suction method to extract the bottom and upper layers of products separately. This suction method ensures that the bottom layer of asphalt and the upper layer of oil are effectively extracted, thereby increasing the yield and purity of the product. This has a positive impact on the efficiency and profit of the production process.
