Description

Technical Field

[0001] This utility model relates to the field of asphalt production technology, and in particular to an asphalt aggregate storage bin. Background Technology

[0002] Asphalt mixture is a composite material mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder. Aggregates are usually stored in storage silos.

[0003] Chinese utility model patent CN215593564U discloses a cold aggregate bin for an asphalt mixing plant, comprising a bin body with an inlet at the top and an outlet at the bottom. A filter plate is installed at the inlet, with a plurality of filter holes evenly distributed on the filter plate. One side of the filter plate is hinged to the inner wall of the inlet, and the movable end of the filter plate is detachably connected to the inner wall of the inlet away from the hinge by a fixing member. By installing a filter plate at the inlet of the bin body, the aforementioned cold aggregate bin prevents aggregate particles larger than the diameter of the filter holes from entering the bin body, thereby making the aggregate particle size within the bin body more uniform and improving the quality of the asphalt mixture.

[0004] When using the cold aggregate bin disclosed in the aforementioned utility model patent, it is necessary to manually lift the movable end of the filter plate upwards to pour the aggregate filtered out of the filter plate into the receiving box, which increases the labor intensity of workers. Moreover, if too much aggregate remains on the filter plate, it will clog the filter plate and affect the normal entry of aggregate into the bin body. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an asphalt aggregate storage bin, which solves the problems of requiring manual cleaning of filter plates and the filter plates being easily clogged, thus affecting the normal entry of aggregates into the bin body.

[0006] According to an embodiment of this utility model, an asphalt aggregate storage bin includes a bin body, the bin body having two non-communicating chambers and two feed inlets respectively corresponding to and connected to the chambers. The bin body is also provided with a mounting frame, the mounting frame having a screening box, and a supporting spring between the mounting frame and the screening box. The screening box is equipped with a vibration motor. A first vertical plate and a second vertical plate are spaced horizontally within the screening box. The screening box also includes a filter plate and a guide plate, with the guide plate located below the filter plate. The filter plate has filter holes. The filter plate and the first vertical plate form a first channel communicating with one of the feed inlets. The first vertical plate, the guide plate, and the second vertical plate form a second channel communicating with the other feed inlet. The filter holes connect the first channel and the second channel.

[0007] Furthermore, a first support plate is provided on the inner wall of the screening box. The height of the first support plate is higher than the top of the first vertical plate. One end of the filter plate overlaps the first support plate and the other end overlaps the top of the first vertical plate.

[0008] Furthermore, the screening box is also equipped with a feed hopper, and one end of the filter plate that overlaps the first support plate is located directly below the feed hopper.

[0009] Furthermore, a second support plate is provided on the side of the first vertical plate. The height of the second support plate is higher than the top of the second vertical plate. One end of the guide plate overlaps the second support plate and the other end overlaps the top of the second vertical plate.

[0010] Furthermore, the screening box is also provided with a first guide hopper, which is connected to the first channel and extends into the feed inlet connected to the first channel.

[0011] Furthermore, the screening box is also provided with a second guide hopper, which is connected to the second channel and extends into the feed inlet connected to the second channel.

[0012] Furthermore, the screening box is also provided with multiple baffles, which are staggered along the length of the filter plate and attached to the upper surface of the filter plate.

[0013] Furthermore, the inner wall of the screening box is provided with a slot, and the baffle plate is provided with a locking block that cooperates with the slot.

[0014] Compared with existing technologies, this utility model has the following advantages: By using a vibrating motor to drive the screening box to vibrate on the mounting frame, the aggregate is poured into the screening box and first falls onto the filter plate. As the vibrating box vibrates, the aggregate moves in the first channel, and the aggregate with a particle size smaller than the diameter of the filter hole passes through the filter hole and enters the second channel and moves along the second channel. This allows the aggregate with a particle size larger than the diameter of the filter hole and the aggregate with a particle size smaller than the diameter of the filter hole to enter the two compartments of the silo body respectively, so as to automatically separate and store aggregates of different particle sizes and avoid aggregate accumulation on the filter plate. It solves the technical problem that existing cold aggregate silos require manual cleaning of the filter plate and the filter plate is prone to clogging, which affects the normal entry of aggregates into the silo body. It produces the technical effect of automatically separating and storing aggregates according to particle size and ensuring that the filter plate remains unobstructed, effectively reducing the labor intensity of workers.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes an asphalt aggregate storage bin for storing aggregates during the asphalt mixture production process.

[0021] Please refer to Figure 1 and Figure 2 The asphalt aggregate storage bin includes a bin body 100, which has two non-communicating chambers 101 and two feed inlets 102 that are respectively connected to the chambers 101. The bin body 100 is also equipped with a mounting frame 200, on which a screening box 300 is mounted, and a support spring 400 is provided between the mounting frame 200 and the screening box 300. A vibration motor 500 is mounted on the screening box 300, which drives the screening box 300 to vibrate on the mounting frame 200. First vertical plates are spaced horizontally inside the screening box 300. The screening box 300 is further provided with a filter plate 303 and a guide plate 304, with the guide plate 304 located below the filter plate 303. The filter plate 303 has filter holes 305. The filter plate 303 and the first vertical plate 301 form a first channel 306 communicating with one of the feed inlets 102. The first vertical plate 301, the guide plate 304, and the second vertical plate 302 form a second channel 307 communicating with the other feed inlet 102. The filter holes 305 connect the first channel 306 and the second channel 307.

[0022] Specifically, the working process of the asphalt aggregate storage bin provided in this embodiment is as follows: When pouring aggregate into the asphalt aggregate storage bin, the vibration motor 500 is started first, and then the aggregate is poured onto the filter plate 303. The screening box 300 vibrates on the mounting frame 200 under the drive of the vibration motor 500, so that the aggregate poured into the screening box 300 and falling onto the filter plate 303 moves in the first channel 306 with the vibration of the vibration box. During the movement of the aggregate on the filter plate 303, aggregate with a particle size smaller than the diameter of the filter hole 305 passes through the filter hole 305. Aggregates with a particle size larger than the filter diameter continue to move along the first channel 306, allowing aggregates with a particle size larger than the filter hole diameter 305 and aggregates with a particle size smaller than the filter hole diameter 305 to enter the two chambers 101 of the silo body 100 respectively. This achieves automatic separation and storage of aggregates with different particle sizes. During the asphalt mixture production process, the required aggregate size can be retrieved from the corresponding chamber 101. Furthermore, the vibration of the vibrating box driven by the vibration motor 500 prevents aggregate from accumulating on the filter plate 303 and clogging the filter holes 305. The asphalt aggregate storage silo provided in this embodiment can automatically separate and store aggregates according to particle size, and ensures that the filter plate 303 remains unobstructed during the process of pouring aggregates into the chamber 101, effectively reducing the labor intensity of workers.

[0023] Please combine Figure 2 and Figure 3 The screening box 300 has a first support plate 308 on its inner wall. The height of the first support plate 308 is higher than the top of the first vertical plate 301. One end of the filter plate 303 is attached to the first support plate 308, and the other end is attached to the top of the first vertical plate 301. The first support plate 308 is provided on the inner wall of the screening box 300 for the filter plate 303 to be installed. The height of the first support plate 308 is higher than the top of the first vertical plate 301. When the two ends of the filter plate 303 are respectively attached to the first support plate 308 and the first vertical plate 301, the filter plate 303 is tilted, so that the aggregate poured on the filter plate 303 moves along the filter plate 303 towards the feed inlet 102 under its own weight, avoiding the aggregate from being stuck on the filter plate 303 and causing the filter plate 303 to be blocked.

[0024] In this embodiment, the screening box 300 is further provided with a feed hopper 309, and one end of the filter plate 303, which overlaps the first support plate 308, is located directly below the feed hopper 309. The feed hopper 309 on the screening box 300 is used to guide the aggregate to be poured onto the filter plate 303, preventing the aggregate from falling out of the screening box 300 when it is poured into the screening box 300, thereby reducing material loss.

[0025] like Figure 3 As shown, a second support plate 310 is provided on the side of the first vertical plate 301. The height of the second support plate 310 is higher than the top of the second vertical plate 302. One end of the guide plate 304 overlaps the second support plate 310, and the other end overlaps the top of the second vertical plate 302. The second support plate 310, which is provided on the side of the first vertical plate 301, is used for the installation of the guide plate 304. The height of the second support plate 310 is higher than the top of the second vertical plate 302, so that when the two ends of the guide plate 304 overlap the second support plate 310 and the second vertical plate 302 respectively, the guide plate 304 can maintain its tilt. The tilt direction of the guide plate 304 is opposite to the tilt direction of the filter plate 303, ensuring that the aggregate entering the second channel 307 enters the corresponding chamber 101 under the guidance of the guide plate 304, preventing the aggregate from accumulating in the second channel 307 and causing blockage.

[0026] like Figure 2 and Figure 3 As shown, the screening box 300 is also provided with a first guide hopper 311. The first guide hopper 311 is connected to the first channel 306 and extends into the feed inlet 102 connected to the first channel 306. The first guide hopper 311 is used to guide the aggregate in the first channel 306 into the corresponding feed inlet 102 and fall into the chamber 101, preventing the aggregate from falling outside the feed inlet 102 due to the vibration of the screening box 300, and ensuring that the first channel 306 and the corresponding chamber 101 remain connected.

[0027] In detail, the screening box 300 is also provided with a second guide hopper 312, which is connected to the second channel 307 and extends into the feed inlet 102 connected to the second channel 307. The aggregate entering the second channel 307 is guided by the second guide hopper 312 through the corresponding feed inlet 102 into the chamber 101, ensuring that the aggregate is smoothly fed from the screening box 300 into the chamber 101.

[0028] Please refer to Figure 1 and Figure 3 The screening box 300 is also provided with a plurality of baffles 313, which are staggered along the length of the filter plate 303 and attached to the upper surface of the filter plate 303. By providing the baffles 313 on the screening box 300 to prevent aggregate from moving on the filter plate 303, the travel distance of the aggregate on the filter plate 303 is increased, allowing the filter plate 303 to fully screen the aggregate and ensuring that aggregate with a particle size smaller than the diameter of the filter hole 305 passes through the filter hole 305 and falls into the second channel 307.

[0029] In this embodiment, the inner wall of the screening box 300 is provided with a slot, and the baffle plate 313 is provided with a locking block 314 that cooperates with the slot. The baffle plate 313 is installed on the screening box 300 through the cooperation of the locking block 314 and the slot, so that the baffle plate 313 and the screening box 300 are firmly engaged, and at the same time, it is convenient to remove the baffle plate 313 from the screening box 300 to increase or decrease the number of baffle plates 313, so as to adjust the stroke of the aggregate on the filter plate 303 as needed.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
