Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a batching and conveying equipment for asphalt production. Background Technology

[0002] During asphalt production, the feed inlet of the batching and conveying equipment needs to handle a variety of materials with vastly different physical properties. These include granular solid materials of varying sizes, such as gravel and sand, as well as liquid asphalt binders with high temperatures and viscosity that changes significantly with temperature, and various powdered additives.

[0003] Most asphalt batching and conveying equipment on the market uses a fixed-angle straight or curved plate as the guide structure at the feed inlet. This design is based on the stable flow of materials under ideal conditions. However, in actual production, different batches of sand and gravel have significant differences in moisture content and particle size distribution. The temperature and viscosity of asphalt binder also change with the production conditions. Fixed-angle guide plates cannot adapt to these changes. Once the material characteristics change, the guiding effect will be greatly reduced, causing the material to stagnate at the feed inlet, affecting production efficiency. Operators may even need to use primitive methods such as hammering to assist in feeding, which is both unsafe and reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a batching and conveying equipment for asphalt production. This equipment can solve the problem that most of the guide structures at the feed inlet adopt straight or curved plates with fixed angles. This design is based on the stable flow of materials under ideal conditions. However, in actual production, the moisture content and particle size distribution of different batches of sand and gravel vary greatly. The temperature and viscosity of asphalt binder also change with the production conditions. The guide plates with fixed angles cannot adapt to these changes. Once the material characteristics change, the guiding effect will be greatly reduced, causing the material to stagnate at the feed inlet, affecting production efficiency. It may even require operators to use some primitive methods such as hammering to assist in feeding, which is both unsafe and reduces production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a batching and conveying equipment for producing asphalt, comprising a feed box, a conveying pipeline, an electric motor and a vibrating motor, wherein a guide plate assembly is provided on the feed box; The deflector assembly includes two deflectors, two adjusting rotating blocks, and four parallel components. When all four parallel components are parallel plates, two parallel component slots are opened on the outer walls of the two deflectors. The four parallel component slots are arranged in pairs, and the four parallel components are rotatably installed inside the corresponding parallel component slots. The two guide plates are rotatably installed inside the feed box, and the two adjusting rotating blocks are rotatably installed on the outer wall of the feed box. Multiple limit bolt slots are opened on the outer wall of the feed box near the adjusting rotating blocks. The outer walls of the two adjusting rotating blocks are fixedly connected with protrusions, and the outer walls of the two protrusions are threaded with limit bolts.

[0006] Preferably, the plurality of the limiting bolt slots are arranged in a circular pattern; Among them, the ends of the two adjusting rotating blocks near the guide plate both extend into the inside of the feed box and are fixedly connected to one end of the corresponding guide plate.

[0007] Preferably, the ends of the two limiting bolts near the limiting bolt grooves are both threaded to the outside of the protrusion and respectively connected to the internal threads of the corresponding limiting bolt grooves; Two deflectors are used together.

[0008] Preferably, a connecting box is fixedly connected to the outer wall of the conveying pipeline, and the interior of the connecting box communicates with the interior of the conveying pipeline; The feed box has four flexible connecting bolts installed at the bottom corners.

[0009] Preferably, an electric motor is fixedly installed at one end of the conveying pipe near the connecting box; The feed box is installed on the upper surface of the connecting box by four elastic connecting bolts that fit into the slots at the four corners of the connecting box.

[0012] Preferably, the vibration motor is mounted on the outer wall of the feed box by four fixing bolts.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Example 1: Reference Figure 1-4 Example of conventional aggregate conveying foundation feeding (parallel plate guide plate + fixed angle adjustment) This embodiment is applicable to the production of ordinary asphalt mixtures, conveying conventional aggregates such as sand, gravel, and mineral powder. Stable material feeding is achieved through the basic parallel plate guide plate and fixed angle adjustment structure to meet daily production needs.

[0022] Structural fit and material feeding process: Four parallel parts 11 are made of 3mm thick Q235 steel plates and are arranged horizontally and parallel. They are rotatably installed in the parallel part groove 12 of the guide plate 10, forming a 45° angle with the guide plate. The guide plate 10 can be rotated by adjusting the rotating block 6 (adjustment angle range 0-30°). The limit bolt 9 is screwed into the limit bolt groove 8 to fix the position. The vibration motor 4 works at a frequency of 30Hz to promote material flow.

[0023] During feeding, the aggregate is guided by the guide plate and slids evenly into the conveying pipe 2 with the assistance of the parallel plate, and the feeding speed is stabilized at 10m / s. 3 / h, by adjusting the angle of the guide plate, the feed rate can be finely adjusted (adjustment accuracy ±10%). When disassembling and cleaning, loosen the limit bolt and rotate the guide plate to remove the parallel plate (time ≤3 minutes).

[0024] Application effects: Suitable for small and medium-sized asphalt mixing plants, meeting the needs of conventional aggregate conveying, with low equipment failure rate, simple maintenance, and aggregate blockage rate of less than 5%.

[0025] Example 2: Reference Figure 5 Example of anti-clogging feeding for high-viscosity ingredients (perforated parallel plate + variable angle guide) This embodiment is designed for conveying highly viscous ingredients such as asphalt and modifiers. It uses a perforated parallel plate and flexible angle adjustment to prevent material adhesion and blockage, ensuring continuous conveying.

[0026] Anti-clogging structure optimization: Parallel component 11 is replaced with a perforated parallel plate 16 (8mm aperture, 35% opening rate) to disperse the pressure of viscous materials. The adjustment angle range of guide plate 10 is expanded to 0-45°. Combined with the densified design of limit bolt grooves (spacing reduced to 15°), fine adjustment is achieved. The frequency of vibration motor 4 is increased to 50Hz to enhance vibration intensity.

[0027] When discharging high-viscosity ingredients, the porous structure ensures a uniform material flow rate (fluctuation ≤8%), and the guide plate can be flexibly adjusted to adapt to different viscosity requirements (e.g., asphalt discharging speed from 5m / s). 3 / h adjusted to 8m 3 / h), the perforated plate design reduces material adhesion by 50%, and the equipment can run continuously for 8 hours without clogging.

[0028] High-viscosity scenario performance: Effectively solves the problem of conveying high-viscosity ingredients, suitable for modified asphalt production, special asphalt mixing and other scenarios, and improves production efficiency by 30%.

[0029] Furthermore, when using this device, when the batching and conveying equipment for producing asphalt is working, firstly, according to the characteristics of the material to be conveyed (such as particle size, viscosity, etc.), the angle of the guide plate 10 is adjusted by adjusting the rotating block 6. Rotating the adjusting rotating block 6 drives the guide plate 10 to rotate inside the feed box 1. When the guide plate 10 reaches a suitable angle, the limiting bolt 9 is screwed into the protrusion 7 and the corresponding limiting bolt groove 8 to fix the angle of the guide plate 10. At this time, the material enters from the inlet of the feed box 1 and flows towards the outlet of the feed box 1 under the guidance of the guide plate 10 and the parallel part 11 (parallel plate or perforated parallel plate 16) that cooperates with it. If the material has poor flowability, the vibration motor 4 can be started. The vibration generated by the vibration motor 4 is transmitted to the internal material through the feed box 1 to assist the material in falling. To prevent material from accumulating and clogging in the feed box 1, the material enters the connecting box 15 through the discharge port of the feed box 1, and then enters the conveying pipe 2 through the connecting box 15. The motor 3 is started, and the motor 3 drives the bolt conveying shaft 14 to rotate in the conveying pipe 2. The bolt conveying shaft 14 pushes the material along the conveying pipe 2 through the spiral blades, and finally discharges it from the discharge port at the end of the conveying pipe 2 away from the motor 3, completing the material batching and conveying process. During the entire operation, the elastic connecting bolt 13 can alleviate the transmission of vibration generated by the vibrating motor 4 to the conveying pipe 2, ensuring the stability of the equipment operation. The two forms of the parallel part 11 can be selected according to the material characteristics. The parallel plate is suitable for guiding general materials, while the perforated parallel plate 16 is suitable for materials that need to be dispersed, improving the adaptability of the equipment to different materials.

[0030] When handling granular solid materials such as stones and sand, the guide plate 10 can be adjusted to a suitable angle in conjunction with the parallel component 11 to effectively disperse the material and prevent blockage caused by concentrated material feeding. When conveying high-temperature liquid asphalt binder or powdered additives, the angle of the guide plate 10 can be adjusted to guide the material to spread and flow evenly, avoiding local accumulation. This solves the problem that traditional fixed guide plates cannot adapt to changes in material characteristics and greatly improves the equipment's ability to handle different materials.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
