Description

Technical Field

[0001] This utility model relates to the technical field of asphalt flow limiting devices, specifically an asphalt flow limiting device for emulsified asphalt production raw materials. Background Technology

[0002] The emulsified asphalt production raw material asphalt flow limiting device is a device used to accurately control the flow rate of raw material asphalt, aiming to solve the problem of difficulty in accurate measurement due to the high viscosity and low fluidity of asphalt.

[0003] A search revealed Chinese patent publication number CN222041444U, which discloses a flow-limiting device for emulsified asphalt production raw material. The device includes a volumetric tank with an inlet pipe connected to its upper side and an outlet pipe connected to its bottom. An overflow port is located on the left side of the tank, and an adjusting plate is slidably connected to the overflow port. The adjusting plate is driven to slide within the overflow port by a power component. A return box is connected to the outer wall of the tank, and a return pipe is connected to the bottom of the return box. A scraper is connected inside the tank, and a telescopic rod is connected to the top of the scraper. The power component mechanically moves the adjusting plate vertically to adjust the flow-limiting capacity of the tank, preventing injury from hot asphalt splashing during manual operation. The adjusting plate and overflow port design allow for convenient and quick confirmation of the flow limit by injecting asphalt into the overflow point. The scraper removes asphalt adhering to the inner wall of the tank after flow, ensuring the accuracy of the asphalt flow after each flow restriction.

[0004] However, asphalt tends to solidify after cooling. In this device, asphalt tends to adhere to the power rod after flowing into the return tank. After cooling, the asphalt on the power rod hardens, making it difficult to clean the asphalt in the return tank. This makes it difficult for the subsequent power rod to adjust the position of the regulating plate. Furthermore, the asphalt adhering to the internal scraper is always inside the tank. After the asphalt hardens, it is difficult to clean, thus reducing the efficiency of the device. Utility Model Content

This device solves the problems of asphalt easily solidifying after cooling, and the asphalt adhering to the power rod after flowing into the return tank. Upon cooling, the asphalt on the power rod hardens, making it difficult to clean the asphalt in the return tank. This results in difficulty in adjusting the position of the adjusting plate using the subsequent power rod. Furthermore, the asphalt adhering to the internal scraper remains inside the tank, and after hardening, it is difficult to clean, thus reducing the device's efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow-limiting device for emulsified asphalt production raw material, comprising a storage pipe and a piston scraper.

A first valve is fixedly installed inside each inclined pipe, and the same overflow pipe is fixedly connected to the left end of each inclined pipe. A storage bottle is sleeved on the lower end of the overflow pipe, thereby facilitating the flow restriction of the asphalt injected into the storage pipe.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figure 1-3This utility model provides a flow-limiting device for emulsified asphalt production raw material asphalt, including a storage pipe 1 and a piston scraper 6. A support ring 13 is fixedly sleeved on the lower end of the storage pipe 1, and multiple support columns 14 are fixedly installed at equal intervals on the lower end of the support ring 13. A U-shaped frame 2 is fixedly installed on the upper end of the storage pipe 1, and a support plate 3 is provided inside the U-shaped frame 2. The piston scraper 6 is located at the lower end of the support plate 3, and the piston scraper 6 and the support plate 3 are fixedly connected by a support rod. A conical seat 7 is rotatably connected to the lower end of the piston scraper 6, and a rotary motor 5 is fixedly installed on the upper end of the piston scraper 6. The output shaft of the rotary motor 5 passes through the piston. The scraper 6 is fixedly connected to the upper end of the conical seat 7. The upper end of the U-shaped frame 2 is fixedly installed with a cylinder 4. The output shaft of the cylinder 4 passes through the interior of the U-shaped frame 2 and is fixedly connected to the upper end of the support plate 3. After cleaning the interior of the storage pipe 1, the cylinder 4 is closed, and the support plate 3 is moved upward until the conical seat 7 is moved above the storage pipe 1. Then, the conical seat 7, scraper 18 and piston scraper 6 exposed outside the storage pipe 1 can be easily cleaned to prevent the hardening of the attached asphalt, which could cause the piston scraper 6 and conical seat 7 to jam or become unusable in subsequent use.

[0017] Example 2 To facilitate the input and output of asphalt materials, in this embodiment, as follows: Figure 1-3As shown, a feed pipe 8 is fixedly installed inside the upper right side wall of the storage pipe 1. Multiple inclined pipes 9 are fixedly installed at equal intervals inside the left side wall of the storage pipe 1. A first valve 10 is fixedly installed inside each inclined pipe 9. The left end of each inclined pipe 9 is fixedly connected to the same overflow pipe 11. A storage bottle 12 is sleeved at the lower end of the overflow pipe 11. A conical pipe 17 is welded to the storage pipe 1 and is located at the lower end of the conical seat 7. A discharge pipe 15 is fixedly installed at the lower end of the conical pipe 17. A second valve 16 is fixedly installed inside the discharge pipe 15. The upper... The end is open, and the sidewalls of the piston scraper 6 and the support plate 3 are slidably attached to the inner sidewall of the storage tube 1, and the piston scraper 6 is tightly attached to the inner sidewall of the storage tube 1. Scrapers 18 are fixedly installed at equal intervals on the sidewall of the conical seat 7. The sidewalls of the scrapers 18 are parallel to the sidewalls of the conical seat 7, and the diameter of the cone formed between the sidewalls of the scrapers 18 at corresponding positions matches the inner diameter of the conical tube 17. The longitudinal height of the conical seat 7 matches the longitudinal depth of the conical tube 17. U-shaped The height of frame 2 is greater than the distance between the support plate 3 and the two side walls of the conical seat 7. When injecting asphalt, cylinder 4 first moves the conical seat 7 to the outside of the storage pipe 1. Asphalt is then injected into the storage pipe 1 through the feed pipe 8. Before injection, the corresponding first valve 10 is opened according to the injection position. When the asphalt inside the storage pipe 1 reaches the position of the inclined pipe 9 corresponding to the opened first valve 10, it enters the discharge pipe 8 through the inclined pipe 9 and then into the storage bottle 12. Then stop the injection and close the first valve 10. Then open the cylinder 4 until the piston scraper 6 enters the storage pipe 1. Then open the second valve 16. At this time, a negative pressure is formed inside the storage pipe 1. When the piston scraper 6 moves downward, it compresses the air and can discharge the asphalt in the storage pipe 1 through the discharge pipe 15 until the conical seat 7 enters the conical tube 17. At the same time, turn on the rotary motor 5 to make the conical tube 17 drive the scraper 18 to rotate, which can clean the inner side wall of the conical tube 17.

[0018] It should be noted that, in this embodiment, as Figure 1-3As shown, during asphalt injection, the cylinder 4 first moves the conical seat 7 to the outside of the storage pipe 1, and then injects asphalt into the storage pipe 1 through the feed pipe 8. Before injection, the first valve 10 at the corresponding position is opened according to the injection position. When the asphalt inside the storage pipe 1 reaches the position of the inclined pipe 9 corresponding to the opened first valve 10, it will enter the discharge pipe 8 through the inclined pipe 9 and then into the storage bottle 12. Then, the injection is stopped, the first valve 10 is closed, and the cylinder 4 is opened again until the piston scraper 6 enters the storage pipe 1. Then, the second valve 16 is opened. At this time, a negative pressure is formed inside the storage pipe 1. When the piston scraper 6 moves downward, By compressing the air, the asphalt in the storage pipe 1 can be discharged outward through the discharge pipe 15 until the conical seat 7 enters the interior of the conical pipe 17. At the same time, the rotary motor 5 is turned on, causing the conical pipe 17 to drive the scraper 18 to rotate, which can clean the inner sidewall of the conical pipe 17. After cleaning the interior of the storage pipe 1, the cylinder 4 is closed, causing the support plate 3 to move upward until the conical seat 7 moves above the storage pipe 1. Then, the conical seat 7, scraper 18 and piston scraper 6 exposed outside the storage pipe 1 can be easily cleaned to prevent the attached asphalt from hardening and causing the piston scraper 6 and conical seat 7 to jam or become unusable in subsequent use.
