Description

Technical Field

[0001] The utility model relates to the field of machine-made sand detection equipment, in particular to a stone powder content determination device. Background Art

[0002] Compared with natural sand, artificial sand (mechanical sand) generally has a higher stone powder content and a larger fineness modulus. The stone powder content has an important impact on the quality of machine-made sand. If the stone powder content is too high, the compactness of the concrete will be reduced and the workability will deteriorate. Too much stone powder will reduce the strength of the cement slurry, reduce the strength of the concrete, and increase the shrinkage rate of the concrete. Therefore, it is necessary to accurately measure the stone powder content in the machine-made sand. The current measurement method is generally to separate the stone powder of the machine-made sand and calculate the ratio of the weight of the stone powder to the total weight to obtain the stone powder content. When screening the stone powder, the existing measuring device is easy to lift the stone powder, causing the stone powder to float in the measuring device or even float out. On the one hand, it will cause pollution to the working environment and be detrimental to the health of the operators. On the other hand, the scattered stone powder is not included in the content, resulting in inaccurate measurement data, which affects the judgment of the quality of the machine-made sand. Utility Model Content

[0003] The utility model aims to provide a stone powder content measuring device, which can prevent stone powder from scattering into the interior of the measuring device or the atmosphere during the screening process, thereby avoiding pollution of the working environment and improving the accuracy of the measurement.

[0009] In the above technical solution, the cover body and the storage barrel are detachably connected, which can ensure that the stone powder falls into the storage barrel and prevent the stone powder from floating in the external atmosphere, thereby avoiding polluting the working environment.

[0010] Furthermore, the screening assembly includes a screen and a vibration motor, the screen is arranged in the main body, the output end of the vibration motor is connected to the screen, and the vibration motor can drive the screen to vibrate.

[0014] Furthermore, a handle is provided at one end of the screen close to the opening.

[0015] In the above technical solution, the handle can facilitate the removal and placement of the screen, making the operation more convenient.

[0016] Furthermore, the exhaust assembly includes a frame and an exhaust fan, and the exhaust fan is arranged on the frame.

[0017] In the above technical solution, the exhaust fan can form negative pressure below the screening assembly, thereby extracting the separated stone powder.

[0018] Furthermore, the lower end of the main body is formed as an inclined surface, and the discharge port is oriented horizontally.

[0019] In the above technical solution, the inclined surface can prevent the stone powder from accumulating at the lower end of the main body, which is conducive to discharging the stone powder from the discharge port.

[0020] Furthermore, a dust sensor is provided between the screening component and the air extraction component.

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0028] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the stone powder content measuring device of the utility model mainly includes a main body 1, a weighing component 2, a screening component 3, and an exhaust component 4. Among them, a cavity is formed in the main body 1, and the upper and lower ends of the main body 1 are respectively provided with a feed port 11 and a discharge port 12 connected to the cavity. The weighing component 2 is arranged adjacent to the main body 1. Specifically, the weighing component 2 can be arranged below the discharge port 12. The screening component 3 and the exhaust component 4 are arranged in the main body 1, the screening component 3 is used to separate the stone powder in the machine-made sand, and the exhaust component 4 is arranged below the screening component 3 and close to the discharge port 12, and the exhaust component 4 is used to discharge the stone powder through the discharge port 12 by negative pressure.

[0029] It can be seen from the above technical solution that a screening component 3 and an exhaust component 4 are provided in the main body 1. The screening component 3 can separate the stone powder in the machine-made sand, and the exhaust component 4 can quickly discharge the stone powder from the discharge port 12 of the main body 1 through negative pressure, so that the stone powder falls into the weighing component 2 for weighing, thereby preventing the stone powder from floating inside the main body 1 or escaping from the main body 1, thereby avoiding polluting the working environment and improving the measurement accuracy.

[0030] The weighing assembly 2 includes a storage barrel 21 for carrying materials and a weighing device 22 for weighing the materials. The weighing device 22 is adjacent to the discharge port 12, and the storage barrel 21 can be placed on the weighing device 22. It is understandable that the weighing device 22 can be an existing one, and the present application will not elaborate on it here. The storage barrel 21 can collect the separated stone powder, and the weight of the stone powder can be obtained by the weighing device 22. When in use, the total weight of the machine-made sand can be weighed by the weighing device 22 before screening, and the content of the stone powder can be obtained by calculating the ratio of the weight of the stone powder after screening to the total weight.

[0031] The discharge port 12 is provided with a cover 13, one end of the cover 13 is connected to the discharge port 12, and the other end can be covered above the storage barrel 21. The cover 13 and the storage barrel 21 are detachably connected to ensure that the stone powder falls into the storage barrel 21, and the stone powder is prevented from floating in the external atmosphere, thereby avoiding pollution of the working environment.

[0032] The screening assembly 3 includes a screen 31 and a vibration motor 32. The screen 31 is arranged in the main body 1. The output end of the vibration motor 32 is connected to the screen 31. The vibration motor 32 can drive the screen 31 to vibrate. During screening, the machine-made sand is put into the main body 1 from the feed port 11 and falls on the screen 31. The vibration motor 32 can drive the screen 31 to vibrate, thereby screening out the stone powder. It can be understood that the aperture of the screen 31 can be set according to the particle size of the machine-made sand to ensure the screening effect.

[0033] In this embodiment, the main body 1 is provided with an opening, and the screen 31 is inserted into the opening, and the screen 31 is configured to be slidable so as to extend from the opening. For example, a guide rail may be provided in the main body 1, and the screen 31 is slidably connected to the guide rail so that the screen 31 can slide in the horizontal direction. When the screening is completed, the screen 31 can be pulled out to remove the machine-made sand in the main body 1 after the screening. In order to facilitate the pushing and pulling of the screen 31, a handle 33 is provided at one end of the screen 31 near the opening, and the handle 33 can facilitate the removal and placement of the screen 31, making the operation more convenient.

[0034] The exhaust assembly 4 includes a frame 41 and an exhaust fan 42, and the exhaust fan 42 is arranged on the frame 41. The exhaust fan 42 exhausts air from the feed port 11 to the discharge port 12, that is, exhausts air from top to bottom, which can form a negative pressure below the screening assembly 3, thereby extracting the separated stone powder.

[0035] The lower end of the main body 1 is formed into an inclined surface, and the discharge port 12 is oriented horizontally. The inclined surface can prevent stone powder from accumulating at the lower end of the main body 1, and is conducive to discharging the stone powder from the discharge port 12.

[0036] A dust sensor 14 is provided between the screening component 3 and the exhaust component 4. The existing dust sensor 14 can be used. The dust sensor 14 can sense the stone powder in the main body 1. When the dust sensor 14 senses that there is no dust, it indicates that the stone powder has been separated.

[0037] In order to facilitate the understanding of the above-mentioned stone powder content measuring device, its working principle is described below: before the measurement, the machine-made sand to be measured is weighed first, and the weighing device 22 can be used for weighing. The displayed data minus the weight of the storage bucket 21 can obtain the total weight of the machine-made sand. After the weighing is completed, the machine-made sand is poured into the main body 1, and the vibration motor 32 is started. The vibration motor 32 drives the screen 31 to vibrate, so that the stone powder is separated and falls. At the same time, the exhaust fan 42 is started and the stone powder is extracted to the discharge port 12. Under the guidance of the inclined surface and the cover body 13, the stone powder falls into the storage bucket 21 through the discharge port 12. When the dust sensor 14 senses that there is no dust inside the main body 1, it means that the stone powder is completely separated. At this time, the screen 31 can be pulled out by the handle 33 to take out the screened sand particles, and the data displayed by the weighing device 22 minus the weight of the storage bucket 21 is the weight of the stone powder. The ratio of the stone powder can be obtained by calculating the ratio of the weight of the stone powder to the total weight of the machine-made sand.
