Description

Technical Field

[0001] The utility model relates to the field of feeding, and more specifically, it relates to a raw material conveyor for SBS modified asphalt production. Background Art

[0002] SBS modified asphalt uses matrix asphalt as raw material, adds a certain proportion of SBS modifier, and makes SBS evenly dispersed in the asphalt through methods such as shearing and stirring. At the same time, a certain proportion of exclusive stabilizer is added to form an SBS blend material, and the good physical properties of SBS are used to modify the asphalt. High-strength SBS modified asphalt has good high-temperature resistance and low-temperature resistance, and has good rutting resistance.

[0003] In the production process of SBS modified asphalt, raw materials need to be put into the mixing equipment in proportion. Here, conveyors are often used for feeding. In order to improve production efficiency, enterprises often prepare multiple mixing equipment for simultaneous production. However, the existing conveyors can often only serve one mixing equipment. This requires configuring a corresponding number of conveyors according to the number of mixing equipment, or constantly moving the conveyor back and forth between multiple mixing equipment. Moreover, the existing conveyors cannot put raw materials in proportion. For each stirring operation, workers need to proportion the raw materials in proportion first, and then send them into the mixing equipment through the conveyor, resulting in low production efficiency.

[0004] Based on the above, the purpose of the present utility model is to provide a raw material conveyor for SBS modified asphalt production to solve the above problems. Content of the Utility Model

There are also multiple discharge ports on the proportioning table and an adjusting mechanism for controlling the discharge of raw materials from different discharge ports, enabling the raw material conveyor to feed multiple equipment without moving and to feed according to the proportion, thereby improving production efficiency.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A raw material conveyor for SBS modified asphalt production includes a floor platform, several screw conveyors are arranged on the floor platform, a proportioning table is arranged at the discharge ports of several screw conveyors, a mixing tank and several discharge tanks are arranged on the proportioning table, an adjusting mechanism for selecting a specified discharge tank for discharging according to requirements is arranged on the mixing tank, connection grooves are arranged between the mixing tank and the discharge ports of several screw conveyors, and a proportioning mechanism for proportioning various raw materials is arranged on several connection grooves.

[0007] By adopting the above technical solution, when SBS color-changing asphalt production and mixing are required, the user connects multiple discharge troughs to different mixing devices respectively, and then simultaneously conveys different raw materials into the proportioning table through several screw conveyors.

A mixing tank 4 and several discharge slots 5 are arranged in the proportioning table 3. An adjusting mechanism is provided on the mixing tank 4 to select a specified discharge slot 5 for discharging according to requirements. The adjusting mechanism includes an adjusting disk 12 rotatably connected to the proportioning table 3. An adjusting groove 13 is arranged on the adjusting disk 12. One end of the adjusting groove 13 is always communicated with the mixing tank 4, and the other end of the adjusting groove 13 can be communicated with discharge slots at different positions by rotating the adjusting disk 12. A second motor 14 is installed on the proportioning table 3. The second motor is a stepping motor, and the output shaft of the second motor 14 is fixedly connected with the adjusting disk 12.

[0024] Connection grooves 6 are arranged between the mixing tank 4 and the discharge ports of several screw conveyors 2. A dispensing mechanism for proportioning various raw materials is arranged on several connection grooves 6. The dispensing mechanism includes a dispensing tank 7 arranged between the connection groove 6 and the mixing tank 4. A roller 8 is rotatably connected in the dispensing tank 7. Several baffles 9 are fixedly connected to the roller 8. An engaging gear 10 is fixedly connected to the roller 8. When dispensing tanks are arranged on both sides of the roller, engaging gears are fixedly connected to both sides of the roller. Two adjacent dispensing tanks 7 are arranged in a staggered manner, and two adjacent engaging gears 10 are meshed with each other.

The output shaft of the first motor 11 is fixedly connected to the nearest roller 8.

[0025] Working principle: When SBS color-changing asphalt production and mixing are required, the user connects several discharge slots 5 to different mixing devices respectively, and then simultaneously conveys different raw materials into the proportioning table 3 through several screw conveyors 2. The raw materials will enter the dispensing tank 7 through the connection groove 6. The user drives the output shaft of the first motor 11 to rotate, and then drives several rollers 8 to rotate through multiple engaging gears 10. The roller 8 will limit the feeding of raw materials through the baffles. The user can set multiple engaging gears 10 to have different diameters and numbers of teeth according to the feeding proportion requirements, forming different transmission ratio differences, so as to control the rollers 8 to rotate at different speeds and realize feeding in proportion.

[0026] After being proportioned by the dispensing mechanism, the raw materials enter the mixing tank 4, then pass through the adjusting groove 13 and the discharge slot 5 and are discharged into the mixing device. When the appropriate raw materials are put into this mixing device, the adjusting disk 12 is driven to rotate by the second motor 14 until the end of the adjusting groove 13 far from the mixing tank 4 is communicated with another discharge slot 5, and then the feeding of another mixing device is started. With such a setting, it is possible to feed multiple devices without moving the conveyor and to feed according to the proportion, improving the production efficiency.
