Description

Technical Field

[0001] This utility model relates to the field of foamed asphalt processing technology, specifically to a foamed asphalt heating and sampling device for testing. Background Technology

[0002] Foamed asphalt is an important industrial raw material, widely used in many fields, especially in road engineering. It is a crucial raw material for road construction. Before use, foamed asphalt needs to undergo testing to check whether its various parameters meet the process requirements, thereby determining whether the processed asphalt is qualified and can be put into use. Testing is a vital part of ensuring project quality during construction.

[0003] Because foamed asphalt requires a high-temperature environment during processing, and the foamed asphalt processing equipment itself operates at high temperatures, there are certain risks associated with sampling at the inlet or outlet. Therefore, a sampling device is installed on the conveying pipe connecting the mixer and the foamed asphalt processor. However, existing heated sampling devices have connecting pipes that are directly connected to the conveying pipe, which presents the following technical problems:

[0004] 1. As a result, when the conveying pipe starts feeding, the asphalt raw material will enter the connecting pipe, making it impossible to sample at different stages of the processing and making it inconvenient to control the amount of samples taken, thus limiting its use.

[0005] 2. After the asphalt is heated and melted inside the connecting pipe, it tends to stick to the inner wall of the connecting pipe, making it inconvenient to clean.

[0006] To address the aforementioned technical problems, this application proposes a heating sampling device for testing foamed asphalt. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] As attached Figure 1 and attached Figure 2 As shown, a heating and sampling device for foamed asphalt for testing includes a conveying pipe 1 and a connecting pipe 2. The connecting pipe 2 is installed below the conveying pipe 1 and communicates with it. The lower end of the connecting pipe 2 is connected to a discharge bend 3. Heating kit 1 4 and heating kit 2 5 are respectively fitted on the outside of the connecting pipe 2 and the discharge bend 3. Heating kit 1 4 and heating kit 2 5 have the same structure, which is a spiral heating wire wound around the outside of the connecting pipe 2 and the discharge bend 3. A protective shell is fitted on the outside of the connecting pipe 2 and the discharge bend 3. The protective shell has a heat preservation effect. The asphalt raw material in the conveying pipe 1 enters the connecting pipe 2 and the discharge bend 3 for heating and melting. A sampling pipe 6 is installed at the tail end of the discharge bend 3. A control valve 7 is installed on the sampling pipe 6. When the control valve 7 is opened, the sample is taken out through the sampling pipe 6 for testing.

[0031] In order to sample the asphalt raw materials transported inside the delivery pipe at different stages, as shown in the attached... Figure 1 Appendix Figure 4 and attached Figure 5As shown, a material control assembly is provided between the top ends of the conveying pipe 1 and the connecting pipe 2. The material control assembly includes a connecting pipe seat 8, which is fixedly installed on the lower side of the conveying pipe 1. The top of the connecting pipe 2 is installed inside the connecting pipe seat 8. A material guide port 9 is provided on the top of the connecting pipe seat 8. A baffle plate 12 is rotatably installed on the inner side of the connecting pipe seat 8. A connecting shaft 11 is installed on the upper side of the baffle plate 12. The top of the connecting pipe seat 8 is provided with a mounting hole 10 for the connecting shaft 11 to pass through. The top end of the connecting shaft 11 extends out of the conveying pipe 1 and is equipped with a handwheel 13. There is a communication between the outer side of the connecting shaft 11 and the conveying pipe 1. A rotary sealing connection is achieved through a sealing gasket. By marking the origin on the handwheel 13 and the connecting pipe 2, the initial position of the baffle plate 12 is below the guide port 9, thus isolating the conveying pipe 1 and the connecting pipe 2. When sampling is required, the handwheel 13 is rotated, which drives the connecting shaft 11 and the baffle plate 12 to rotate, rotating the baffle plate 12 to the connecting pipe seat 8. On the other side inside, the conveying pipe 1 and the connecting pipe 2 are connected, allowing the asphalt raw material conveyed in the conveying pipe 1 to enter the interior of the connecting pipe 2. The driving method of the connecting shaft 11 can be replaced with a conventional motor drive depending on the installation environment and operating space.

[0032] Example 2

[0033] Based on Example 1, in order to facilitate the transportation of molten asphalt and the cleaning of the pipe wall, as shown in the attached... Figure 2 and attached Figure 3 As shown, a material guiding assembly is installed on the inner side of the upper section of the discharge bend 3. The material guiding assembly includes a rotating shaft 15 and a spiral scraper 16. The spiral scraper 16 is wound around the rotating shaft 15 as its axis and installed on the outside of the rotating shaft 15. The rotating shaft 15 and the spiral scraper 16 are located on the inner side of the upper section of the discharge bend 3 and extend into the interior of the connecting pipe 2. The outer wall of the spiral scraper 16 is in contact with the inner wall of the upper section of the discharge bend 3 and the inner wall of the connecting pipe 2. A motor 14 is installed on the lower side of the discharge bend 3. The shaft end of the motor 14 is connected to the rotating shaft 15. After the asphalt raw material is fed into the interior of the connecting pipe 2, it is first heated and melted inside the connecting pipe 2. Part of the asphalt raw material passes through the spiral scraper 16 and enters the inside of the discharge bend 3. It is heated and melted inside the discharge bend 3 to prevent material accumulation and poor melting effect. After it is completely melted, the motor 14 is started to transport the asphalt in the connecting pipe 2 and scrape off the asphalt on the inner wall of the connecting pipe 2 and the upper inner wall of the discharge bend 3 to prevent asphalt adhesion and increase subsequent cleaning work. The inner wall of the connecting pipe 2 and the discharge bend 3 are sealed by threads and gaskets. After sampling, they can be disassembled and the inner walls of the connecting pipe 2, the discharge bend 3 and the spiral scraper 16 can be cleaned for subsequent use.
