Description

Technical Field

[0001] This utility model relates to the field of concrete silo technology, and in particular to a mixing plant silo with a function of monitoring aggregate moisture content. Background Technology

[0002] In the concrete production process, precise control of the water-cement ratio plays a decisive role in the quality of concrete.

[0003] Currently, many concrete mixing plants lack monitoring of aggregate moisture content. Some construction units, for the sake of convenience, indiscriminately sprinkle water into aggregates such as crushed stone and washed sand, resulting in an excessively high water-cement ratio in the concrete, which seriously affects the quality of the project. This unstable water-cement ratio may lead to problems such as insufficient concrete strength and reduced durability. In various construction projects, whether it is the load-bearing structure of high-rise buildings or the foundation construction of roads and bridges, safety hazards may be created due to the uncontrolled water-cement ratio. Therefore, in order to monitor the moisture content of aggregates in real time, this device is designed as a mixing plant silo with aggregate moisture content monitoring function. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing plant silo with aggregate moisture content monitoring function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mixing plant silo for monitoring aggregate moisture content includes a silo, and a moisture detection mechanism is installed inside the silo. The moisture detection mechanism includes multiple moisture detectors that are detachably installed on the four side walls of the silo via an installation mechanism. The detection end of the moisture detectors moves through the side walls of the silo and extends into the interior of the silo.

[0007] The above technical solution further includes: the installation mechanism includes two clamps, which are respectively clamped on both sides of the moisture detector; an adjustment component is provided on the outer wall of the hopper, which is used to adjust the distance between the two clamps so as to fix the moisture detector to the side wall of the hopper through the two clamps.

[0008] The adjustment assembly includes a bidirectional lead screw rotatably mounted on the side wall of the hopper, a threaded slider fixedly mounted on the outer wall of the clamp, the threaded slider being threadedly connected to the outer wall of the bidirectional lead screw, and a rotating block fixedly mounted at the middle position of the outer wall of the bidirectional lead screw.

[0009] A limiting rod is provided below the card holder, and a limiting slider is fixedly installed on the bottom wall of the card holder. The limiting slider is slidably connected to the outer wall of the limiting rod.

[0010] A filter screen frame is fixedly installed on the inner wall of the silo, and the detection end of the moisture detector is located inside the filter screen frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, a moisture detection mechanism is provided. The moisture content of the aggregate inside the silo can be detected in real time, so as to reduce the mixing water according to the moisture content of the aggregate and ensure the water-cement ratio of the concrete.

[0013] 2. In this utility model, a filter screen frame is provided. The filter screen frame can block unconventional solid sand and gravel blocks, thereby preventing large sand and gravel blocks from hitting the detection end of the moisture detector during the falling process and reducing the risk of damage to the moisture detector.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] See attached document Figure 1-5The hopper includes a 10, and a moisture detection mechanism is installed inside the hopper. The moisture detection mechanism includes multiple moisture detectors 20 that are detachably installed on the four sides of the hopper 10 via an installation mechanism. The detection end of the moisture detector 20 moves through the side wall of the hopper 10 and extends into the interior of the hopper 10. The moisture detectors 20 can detect the moisture content in the sand and gravel.

[0024] The mounting mechanism includes two clamps 31, which respectively hold the moisture detector 20 on both sides. An adjustment component is provided on the outer wall of the hopper 10 to adjust the distance between the two clamps 31, so that the moisture detector 20 can be fixed to the side wall of the hopper 10 by the two clamps 31. Here, the mounting mechanism is provided to fix the moisture detector 20 to the side wall of the hopper 10. That is, when fixing the moisture detector 20 to the side wall of the hopper 10, it is only necessary to clamp and fix the moisture detector 20 by the two clamps 31. It should also be noted that when disassembling the moisture detector 20, it is only necessary to release the clamps 31 from the moisture detector 20, and then pull the detection end of the moisture detector 20 out of the through hole on the side wall of the hopper 10.

[0025] The adjustment assembly includes a bidirectional lead screw 33 rotatably mounted on the side wall of the hopper 10, a threaded slider 32 fixedly mounted on the outer wall of the clamp 31, the threaded slider 32 being threadedly connected to the outer wall of the bidirectional lead screw 33, and a rotating block 34 fixedly mounted at the middle position of the outer wall of the bidirectional lead screw 33. The adjustment assembly is used to clamp the two clamps 31 onto the outer wall of the moisture detector 20. Specifically, the rotating block 34 is rotated, causing the bidirectional lead screw 33 to rotate. The threads on both sides of the outer wall of the bidirectional lead screw 33, with different directions, mesh with the threads on the inner wall of the threaded slider 32, thereby causing the two threaded sliders 32 to move towards / away from each other. This, in turn, causes the two clamps 31 to move towards / away from each other, thus clamping and fixing the moisture detector 20 using the two clamps 31.

[0026] A limiting rod 42 is provided below the card holder 31, and a limiting slider 41 is fixedly installed on the bottom wall of the card holder 31. The limiting slider 41 is slidably connected to the outer wall of the limiting rod 42. In order to improve the stability of the movement of the card holder 31, the limiting slider 41 and the limiting rod 42 are provided. That is, when the card holder 31 moves, the limiting slider 41 can slide on the outer wall of the limiting rod 42, thereby limiting the movement direction of the card holder 31 and preventing the card holder 31 from rotating when the bidirectional lead screw 33 is rotated. It should also be noted that both ends of the limiting rod 42 are provided with blocking blocks. The diameter of the blocking blocks is larger than the inner diameter of the through hole on the limiting slider 41, that is, the limiting rod 42 will not detach from the limiting slider 41.

[0027] A filter screen frame 50 is fixedly installed on the inner wall of the hopper 10, and the detection end of the moisture detector 20 is located inside the filter screen frame 50. Since larger pieces of sand and gravel inevitably exist occasionally, the filter screen frame 50 is installed to prevent these larger blocks from impacting the detection rod of the moisture detector 20. It should also be noted that the mesh size of the filter screen frame 50 is equal to or slightly larger than that of ordinary sand and gravel. This allows ordinary sand and gravel to flow through the filter screen frame 50, while larger pieces are caught on the filter screen frame 50 and then move down the inclined side wall of the filter screen frame 50. This prevents larger pieces of sand and gravel from impacting the detection rod of the moisture detector 20, reducing the probability of damage to the moisture detector 20 and extending its service life.

[0028] In this embodiment, the moisture content of the aggregate inside the silo 10 can be detected in real time by a moisture detection device, so that the mixing water can be reduced according to the moisture content of the aggregate, thus ensuring the water-cement ratio of the concrete.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
