Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture admixtures, and in particular to a device for dynamic dispensing of anti-icing agents for asphalt mixtures. Background Technology

[0002] With the advancement of technology, more and more chemical substances have emerged as admixtures added to asphalt mixtures. For example, anti-icing agents can lower the freezing point of water to below zero, thereby inhibiting freezing or accelerating melting in low-temperature environments. This can alleviate some of the winter snow removal pressure in provinces with heavy snowfall.

[0003] However, traditional mixing plants do not have an external admixture feeding device for anti-icing agents, and can only rely on manual feeding. This not only has a high risk factor, but also makes it difficult to control the amount of additives. As a result, the quality of asphalt mixtures will decrease, and the performance in winter will also be affected.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Example: This application provides a device for dynamically dispensing anti-icing agents in asphalt mixtures, referring to... Figures 1-2 It includes: a support frame 1, on which an inclined feeding pipe 2 is fixed, with a discharge port at the bottom of the top end of the pipe 2, and a spiral blade 3 rotating inside the feeding pipe 2. The support frame 1 is also fixed with a power mechanism for driving the spiral blade 3 to rotate. A fixed frame 4 is fixedly connected to a support frame 1, and a weighing sensor 5 is fixed on it. More specifically, multiple weighing sensors 5 are evenly distributed. The measuring end of the weighing sensor 5 carries a hopper 6, and the output end of the hopper 6 is fed by a feeding pipe 2. More specifically, the hopper 6 as a whole is only supported by the weighing sensor 5. The weighing sensor 5 can weigh the hopper 6 and the anti-icing agent inside the hopper 6. The crushing mechanism 7 is fixedly connected to the support frame 1, and the output end of the crushing mechanism 7 feeds the material into the hopper 6. The specific operation process of this device is as follows: The crushing mechanism 7 first crushes the added anti-icing agent. The crushed anti-icing agent is then transported to the silo 6 carried by the weighing sensor 5. The weighing sensor 5 weighs the anti-icing agent in the silo 6 in real time. By monitoring and calculating the amount of weight reduction of the anti-icing agent in the silo 6 per unit time, the actual amount of anti-icing agent added is determined. The anti-icing agent in the silo 6 falls into the inclined feeding pipe 2. At the same time, the power mechanism drives the spiral blade 3 in the feeding pipe 2 to rotate. The rotation of the spiral blade 3 stably transports the anti-icing agent to the asphalt mixture mixing system to complete the feeding. This device uses a crushing mechanism 7 to crush the anti-icing agent, ensuring smooth feeding of the anti-icing agent. It uses a weighing sensor 5 to monitor in real time and calculates the actual amount added by measuring the weight reduction of the anti-icing agent in the hopper 6 per unit time. Combined with the spiral blade 3, it achieves stable feeding and conveying, which reduces the safety risks of manual operation and controls the amount of anti-icing agent added, effectively ensuring the quality of asphalt mixture.

[0020] As a preferred embodiment of the above, refer to Figure 2 The crushing mechanism 7 includes a housing 71 with a feed inlet, two spiral blades 72 rotatably mounted inside the housing 71, and a power mechanism 2 for driving the two spiral blades 72 to rotate. Reference Figure 3The two spiral blades 72 are staggered, and some of the blades of the two spiral blades 72 overlap to improve the crushing effect; When in use, the anti-icing agent is fed into the inlet of the outer shell 71. The power mechanism 2 is started and drives the two staggered spiral blades 72 inside the outer shell 71 to rotate synchronously. The rotation of the two spiral blades 72 squeezes and shears the fed anti-icing agent. The crushed raw material is then transported to the silo 6.

[0021] As a preferred embodiment of the above, refer to Figure 3 The edges of the spiral blades 272 are toothed; When in use, the edges of the spiral blades 272 are set to be toothed to enhance the cutting ability against de-icing agents. This not only allows for more efficient crushing of agglomerated or large-particle-size raw materials into fine particles that meet the feeding requirements, but also improves the uniformity of crushing.

[0022] As a preferred embodiment of the above, refer to Figure 2 The bottom of the outer casing 71 is a discharge pipe 73, which extends into the hopper 6, and a flexible connection 10 is provided in the gap between the two; more specifically, the discharge pipe 73 is located at the end of the outer casing 71 away from the feed inlet; When in use, the discharge pipe 73 extends into the hopper 6 with a gap between them, which will not affect the position of the hopper 6, thus ensuring the accuracy of the weighing by the weighing sensor 5; the flexible connection 10 effectively prevents material leakage during the conveying process and avoids material waste.

[0023] As a preferred embodiment of the above, refer to Figure 1 The wall of the feeding tube 2 is partially transparent; more specifically, the materials that can be used are high borosilicate glass, polycarbonate or acrylic, and the transparent part can be installed at the feeding tube 2 by means of fixed connection or movable connection. During use, the use of a rigid, transparent partial pipe wall allows staff to directly observe the conveying status of the anti-icing agent inside the feed pipe 2, promptly detect and quickly handle abnormalities such as raw material blockage and uneven conveying.

[0024] As a preferred embodiment of the above, refer to Figure 1 The bottom of the support frame 1 is equipped with rollers 8; When in use, rollers 8 are installed at the bottom of the support frame 1, which greatly improves the mobility and convenience of the entire equipment. Workers can easily move the equipment to the designated working position of the asphalt mixing plant.

[0025] As a preferred embodiment of the above, refer to Figure 2 It also includes a control console 9, which is used to receive the weight data measured by the weighing sensor 5 and control the rotation speed of the spiral blade 3 by the weight change. During use, the weighing sensor 5 monitors the weight of the anti-icing agent in the hopper 6 in real time and transmits the data to the control console 9. The control console 9 determines the actual feeding rate by calculating the weight change per unit time. When a deviation is detected between the weight change and the preset addition amount, the control console 9 automatically adjusts the output of the power mechanism 1, thereby changing the rotation speed of the spiral blade 3: if the weight decreases too slowly, the rotation speed is increased to speed up the conveying; if the weight decreases too quickly, the rotation speed is decreased to slow down the conveying. Through this dynamic control, the amount of anti-icing agent added always meets the set requirements.

[0026] As a preferred embodiment of the above, a flexible connection 10 is provided at the gap between the output end of the hopper 6 and the feeding pipe 2; During use, a flexible connection 10 is installed at the gap between the output end of the hopper 6 and the feeding pipe 2. This can prevent the rigid contact between the two from causing additional force interference to the position of the hopper 6 or the weighing sensor 5, and the sealing of the flexible connection 10 can prevent the anti-icing agent from leaking during the process of entering the feeding pipe 2 from the hopper 6.

[0027] Preferably, the flexible connection 10 can be a tubular sleeve made of canvas, which is fixed to the docking part of the output end of the hopper 6 and the feeding pipe 2 by clamps. The flexibility of the canvas absorbs the vibration during the operation of the equipment and avoids rigid collisions. Alternatively, it can be a rubber corrugated pipe, whose corrugated structure can expand or slightly bend with the relative movement of the connecting parts, so as to achieve sealing and leak prevention without hindering the slight displacement between the parts. It is widely used in pipeline docking scenarios that require buffering and sealing.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
