Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of asphalt production equipment, in particular to an auxiliary agent quantitative feeding device for asphalt production. Background Art
[0002] In modern road construction, asphalt is a commonly used paving material, and its performance directly affects the service life and safety of the road. In order to improve the performance of asphalt mixture, a variety of auxiliary agents, such as resin, rubber powder, mineral fillers, etc., need to be added to the base asphalt during the production process. These additives can improve the aging resistance, heat resistance, adhesion and overall mechanical properties of the final product.
[0003] At present, the common practice of adding adjuvants in asphalt production is to use a hopper with a metering pump for quantitative feeding. This method adjusts the dosage of adjuvants by controlling the running time and rate of the pumping mechanism. However, this method has the following shortcomings:
[0004] First, the equipment cost is high. Metering pumps are usually expensive, especially high-precision metering pumps. For asphalt production companies, high equipment investment will increase production costs.
[0005] Second, the metering pump is cumbersome to operate and complex to maintain. The operator needs to adjust the parameters of the metering pump according to different production needs. At the same time, the structure of the metering pump is relatively complex and requires regular maintenance and calibration, which increases the operation and maintenance costs of the equipment.
[0006] Therefore, we propose an auxiliary agent quantitative feeding device for asphalt production to solve the above problems. Utility Model Content

The four end sides of the cross are fixedly embedded with a fixed cylinder. The fixed cylinder opens upward, and a plunger is slidably inserted at the upper port. The plunger is slidably connected to the inner wall of the feed pipe. The bottom of the fixed cylinder is threadedly connected to an adjusting rod.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0023] The present application provides an auxiliary agent quantitative feeding device for asphalt production, which is mainly used to solve the problem that the equipment cost in the prior art is high. The metering pump is usually expensive, especially the metering pump with high precision. For asphalt production enterprises, the high equipment investment will increase the production cost. In addition, the metering pump is cumbersome to operate and complex to maintain. The operator needs to adjust the parameters of the metering pump according to different production needs. At the same time, the structure of the metering pump is relatively complex and requires regular maintenance and calibration, which increases the operation and maintenance cost of the equipment. The following technical solutions are provided, which will be combined with Figure 1-Figure 3 Make a detailed description:
[0024] An auxiliary agent quantitative feeding device for asphalt production, comprising:
[0025] The installation cylinder 1 is opened downward and is arranged at the feeding port of the coking furnace. The top annular array of the installation cylinder 1 is connected to the feeding pipe 2. The feeding pipe 2 is a transparent plastic pipe, and the outer wall thereof is marked with a scale line 201;
[0026] The quantitative mechanism 3 is used to adjust the addition amount of each auxiliary agent. The quantitative mechanism 3 includes an electric telescopic rod 301 installed on the top of the mounting cylinder 1. The piston end of the electric telescopic rod 301 penetrates the top wall of the mounting cylinder 1 and is connected to a cross 302. The four end sides of the cross 302 are fixedly embedded with a fixed cylinder 303. The fixed cylinder 303 opens upward, and a plunger 304 is slidably inserted at the upper port. The plunger 304 is slidably connected to the inner wall of the feed pipe 2. The bottom of the fixed cylinder 303 is threadedly connected to an adjusting rod 305. The end of the adjusting rod 305 located inside the fixed cylinder 303 is rotatably connected to the plunger 304 through a bearing.
[0027] The specific implementation process and principle of the auxiliary agent quantitative feeding device for asphalt production are as follows:
[0028] The first step is to adjust the position of the plunger 304 in the initial state of the electric telescopic rod 301 (the piston end is not extended, and the cross 302 is in conflict with the top wall of the installation cylinder 1) according to production requirements. The specific method is to rotate the adjustment rod 305 to drive the plunger 304 to move upward until the plunger 304 reaches the specified height inside the feed pipe 2. The height corresponds to the scale line 201, which is the amount of auxiliary material to be added;
[0029] The second step is to load the auxiliary agents to be added into different feed pipes 2. Each feed pipe 2 corresponds to one auxiliary agent. After adding, it is necessary to ensure that each auxiliary agent is parallel to the upper end of the feed pipe 2.
[0030] The third step is to open the coking furnace feed port, start the electric telescopic rod 301, and drive the cross 302 to move downward. When the plunger 304 leaves the lower end of the feed pipe 2, the auxiliary agent in the feed pipe 2 can fall smoothly into the coking furnace, thereby completing the coking furnace.
[0031] The auxiliary agent quantitative feeding device for asphalt production adopts simple mechanical structures such as an electric telescopic rod 301 and a plunger 304, avoiding the use of expensive metering pumps and greatly reducing equipment costs. By adjusting the initial position of the plunger 304 (the length of the plunger 304 inserted into the feed pipe 2), the staff can directly determine the amount of auxiliary agent added by observing the scale line 201 on the feed pipe 2. The operation is simple and intuitive. At the same time, the device has a simple structure and does not require regular maintenance and calibration, which reduces the operation and maintenance costs of the equipment.
[0032] like Figure 1 As shown, in some embodiments, a guide hopper 202 is fixedly provided at the upper end of the feed pipe 2. More specifically, the guide hopper 202 is provided to facilitate the efficient and accurate introduction of the auxiliary agent into the feed pipe 2. The guide hopper 202 can effectively guide the auxiliary agent into the feed pipe 2 to avoid overflow or waste of the auxiliary agent during the feeding process.
[0033] like Figure 1 As shown, in some embodiments, the zero mark of the scale line 201 is located at the upper end of the feed tube 2. More specifically, the zero mark serves as an initial reference point, and the operator can easily determine the final position of the plunger 304, thereby calculating the distance that the plunger 304 needs to move to reach a predetermined amount of auxiliary agent added. By observing the position of the plunger 304 relative to the scale line 201, the operator can control the amount of auxiliary agent added very accurately, because each unit scale represents a certain volume of auxiliary agent.
[0034] like Figure 3 As shown, in some embodiments, the plunger 304 is a butyl rubber plug. More specifically, butyl rubber has excellent chemical stability and can resist corrosion from most chemicals, ensuring that it will not react when in contact with the auxiliary agent, thereby maintaining the original properties of the auxiliary agent. At the same time, butyl rubber has excellent sealing properties to prevent leakage of the auxiliary agent. In addition, butyl rubber can remain stable at high temperatures, which allows the plunger 304 to be used in a high-temperature production environment without damage, ensuring the long-term durability of the feeding device.
[0035] like Figure 1 As shown, in some embodiments, a bracket 4 is fixedly provided at the bottom annular array of the mounting cylinder 1, the bracket 4 is L-shaped, and the bottom end thereof is fixedly provided at the edge of the coking furnace feed port. More specifically, the design of the L-shaped bracket 4 provides a sturdy support frame for the mounting cylinder 1, so that the device can withstand forces from all directions and remain stable during operation.
[0036] like Figure 3As shown, in some embodiments, an arc-shaped notch 101 is constructed at a position corresponding to the fixed cylinder 303 on the bottom side of the outer wall of the mounting cylinder 1. More specifically, the arc-shaped notch 101 provides sufficient operating space for the staff, making the rotation of the adjustment rod 305 more convenient. The staff can easily grasp and rotate the adjustment rod 305 with their hands or tools without being hindered by the mounting cylinder 1.
[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
