Description

Technical Field

[0001] This utility model relates to the field of asphalt batching and dosing mechanisms, and in particular to a modified asphalt batching and dosing device. Background Technology

[0002] The modified asphalt batching and dosing device is a piece of equipment specifically designed for the production of modified asphalt. Its core functions are precise batching and efficient dosing.

[0003] In the production of modified asphalt, the dosing operation is one of the key steps to ensure the performance of the asphalt. Traditional dosing methods often use dosing pumps, which, while simple and direct, have some limitations in practical applications, especially when facing large-scale production needs.

[0004] The main problem with dosing pumps is their relatively small input capacity, which makes it difficult to meet the demands of large-scale, rapid addition of additives in mass production. Furthermore, dosing pumps may experience problems such as poor delivery or blockages due to factors like the high viscosity of asphalt and the particle size of additives, further impacting production efficiency. Utility Model Content

[0005] The main objective of this invention is to provide a chemical dosing device for modified asphalt batching production, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A modified asphalt batching production dosing device includes a support frame, a support base, a modified asphalt batching tank, a conveying mechanism, a control cabinet, and a feed inlet. The conveying mechanism and the modified asphalt batching tank are mounted on the support base. The conveying mechanism is connected to the modified asphalt batching tank and injects modified asphalt batching into the tank. The support frame is located at the four corners of the support base, and the control cabinet is mounted on the support frame. The feed inlet is located at the upper end of the modified asphalt batching tank.

[0008] A support isolation frame is provided between the modified asphalt batching tank and the support frame, and an installation base is installed at the upper end of the support isolation frame.

A first electric control valve is installed on the dosing feed pipe, and the opening and closing of the dosing feed pipe is controlled by the first electric control valve.

[0009] An instrument is installed at the upper end of the connecting pipe, and a second electrically controlled valve is installed at the upper end of the instrument. A dosing and discharge pipe is installed at the upper end of the second electrically controlled valve. The dosing and discharge pipe extends to the inlet and adds chemicals to the modified asphalt mixing tank through the dosing and discharge pipe.

[0010] As a preferred embodiment of this application, the support frame, support base and support isolation frame are fixed by fasteners, and anti-slip pads are provided at the connection between the support frame and the support base. The support frame is provided with support bars inside the frame, the legs of the modified asphalt batching tank are installed on the support bars by fasteners, and the material conveying mechanism is installed on the support bars by bolts and clamps.

[0011] As a preferred embodiment of this application, the mounting base is fixed to the support isolation frame by bolts, the mounting base is fixed to the dosing pump by fasteners, and the dosing feed pipe, connecting pipe and dosing pump are connected by connecting flanges, and a sealing ring is provided at the connection.

[0012] As a preferred embodiment of this application, the first electrically controlled valve is connected to the dosing feed pipe via a connecting flange, and the connecting pipe, instrument, second electrically controlled valve and dosing discharge pipe are all connected via a connecting flange;

[0013] As a preferred embodiment of this application, the instrument is an online monitoring system, which includes a flow meter and a concentration meter;

[0014] As a preferred embodiment of this application, the discharge port of the dosing and discharge pipe is a flared mouth, which faces the inlet. The flared mouth and the dosing and discharge pipe are connected by threads, and a sealing ring is provided at the connection between the flared mouth and the dosing and discharge pipe.

[0016] Precise control of the first electrically controlled valve allows for accurate adjustment of the dosing flow rate to meet varying production needs. Simultaneously, the efficient operation of the dosing pump ensures rapid and stable delivery of modified asphalt to the asphalt batching tank, improving production efficiency. The interconnected design between the dosing mechanism and the asphalt batching tank enables automated dosing, reducing the tediousness and errors of manual operation. Furthermore, the application of an online monitoring system allows for real-time monitoring of the flow rate and concentration during dosing, ensuring accuracy and consistency and ultimately improving the quality of the modified asphalt.

[0017] By securing and sealing components such as fasteners, connecting flanges, and sealing rings, the tightness of all connections and leakage prevention are ensured, improving the safety and reliability of the equipment. Meanwhile, the stable support of the support frame, support base, and support isolation frame, along with the application of anti-slip pads and support strips, further enhances the stability and durability of the equipment, extending its service life. Through modular design, the connections between various components are simple and clear, facilitating disassembly and replacement.

[0027] To further enhance the stability and durability of the device, the support frame 1, support base 2, and support isolation frame 3 are fixed together with fasteners. Anti-slip pads are provided at the connection between the support frame 1 and the support base 2 to prevent slippage during operation. Support bars are provided inside the support frame 1 to provide additional support. The legs of the modified asphalt batching tank 4 are mounted on the support bars with fasteners, while the conveying mechanism 5 is mounted on the support bars with bolts and clamps. This design not only ensures the stability and reliability of the device but also facilitates maintenance and component replacement.

[0028] Mounting base 8 is bolted to the support isolation frame 3, and mounting base 8 is fixed to the dosing pump 9 with fasteners. The dosing inlet pipe 10, connecting pipe 12, and dosing pump 9 are connected via connecting flanges, with sealing rings at the connections to ensure tightness and prevent leakage. The first solenoid valve 11 is connected to the dosing inlet pipe 10 via a connecting flange.
