Description

Technical Field

[0001] The utility model belongs to the field of building materials testing, and particularly relates to a building aggregate cleaning device. Background Art

[0002] Aggregate is one of the most used materials in concrete. Before using building aggregate, it is necessary to detect its various physical and chemical properties. Only when its various physical and chemical properties meet the regulations in the corresponding national standards or industry standards can the building aggregate be used.

[0003] The stone powder content and mud content are the contents that must be detected for building aggregate. The traditional detection method is as follows: manually wash the aggregate in the container repeatedly by hand to separate the fine particles or dust, silt and clay from the aggregate, and then pour the turbid water into the sieve to filter out the particles with the specified particle size in the specification. Repeat the above steps until the water in the washing container becomes clear. This method is very time-consuming and laborious and may hurt the hands, because the operator needs to wash the aggregate by hand repeatedly many times. Especially for coarse aggregate, the gloves are very easy to be scratched by the aggregate during the washing process, which may cause injuries to fingers and other parts. In addition, if the manual washing is not uniform enough, some fine particles or dust, silt and clay will remain on the aggregate, resulting in detection errors. Content of the Utility Model

[0004] The utility model provides a building aggregate cleaning device, which can save labor and has the advantages of uniform cleaning, high-efficiency and accurate test, time-saving and labor-saving, and water-saving.

[0005] A building aggregate cleaning device is characterized in that: it includes a cleaning box, a filter screen, a water-blocking handle, a rubber plug and a support frame. The cleaning box is a square-columnar box without a top plate. Grooves for supporting the filter screen are respectively arranged on the upper parts of the left and right inner sides of the cleaning box. The size of the filter screen matches the internal size of the cleaning frame. Hooks are welded on both the left and right sides of the filter screen and the filter screen is hung on the grooves through the hooks. A partition is arranged below the filter screen. The partition is welded to the inner side of the cleaning box around. A notch from front to back is opened in the middle of the partition. A baffle is arranged at the bottom of the notch inward, and an opening corresponding to the notch is opened at the corresponding position on the front side of the cleaning box. The water-blocking handle can be inserted from the opening to block the notch and is supported by the baffle. Symmetrical handles are arranged at the tops of the front and rear side plates of the cleaning box. An outlet is opened at the bottom of the front side plate of the cleaning box and the outlet is blocked by a rubber plug.

[0006] Furthermore, the thickness of each plate of the cleaning box is ≥ 0.5 cm, the internal length of the box body is ≥ 30 cm, the height is ≥ 80 cm, the width of the notch on the front side plate is ≥ 10 cm, and the height is ≥ 1 cm.

[0007] Furthermore, the filter screen is a single-layer filter screen or a double-layer filter screen. The single-layer filter screen is used when cleaning fine aggregate, and the double-layer filter screen is used when cleaning coarse aggregate.

[0008] Furthermore, the water-blocking handle consists of a handle and a rectangular plate. The handle is a cylinder with a length of ≥ 10 cm and a diameter of ≥ 2 cm. The rectangular plate has a length of ≥ 10 cm, a width of ≥ 10 cm, and a thickness matching the width of the notch on the front side plate of the cleaning tank.

[0009] Furthermore, a support frame is also provided at the bottom of the cleaning tank. The support frame is a triangular prism with a height of ≥ 30 cm and a side length of ≥ 6 cm.

[0010] The beneficial effects of the present utility model are as follows:

[0011] (1) The device has two ways to clean the aggregate, and neither requires manual rinsing. It is characterized by simple operation, time-saving and labor-saving. The first way: after the aggregate is soaked in water, place the cleaning tank on the support frame, then hold the handle on the cleaning frame and shake the frame to move the aggregate, so that the mud on it falls off to achieve the cleaning purpose; the second way: after the aggregate is soaked in water, place the cleaning tank on the concrete vibrating table, and let the aggregate move by the vibration of the concrete vibrating table so that the mud on it falls off to achieve the cleaning purpose.

[0012] (2) The water-blocking handle of the present device has dual functions, which makes the device have the characteristics of water saving and improving the cleaning effect of the aggregate. When the water-blocking handle is spliced with the notch plate of the cleaning frame, only part of the water is needed to completely soak the aggregate. After the aggregate is cleaned once, just remove the water-blocking handle and drain the muddy water containing mud to the bottom of the cleaning frame. Repeat the above steps to clean the aggregate multiple times until the water in the aggregate is no longer turbid. In addition, the water-blocking handle can also be used as a simple trowel. After removing the water-blocking handle and draining the muddy water, it can be used to turn the aggregate on the filter screen to ensure more thorough subsequent cleaning of the aggregate.

[0013] (3) The cleaning frame of the present device has a large volume and can realize the function of draining the muddy water at the bottom after multiple cleanings of the aggregate. Especially when using the concrete vibrating table to assist in cleaning, there is no need to repeatedly remove the cleaning frame to drain the muddy water, which is characterized by convenient use and greatly improving the test efficiency.

[0014] (4) The filter screen of the present device is replaceable, and the filter hole shapes and side lengths of different filter screens are different. Therefore, the device can detect the physical and chemical properties such as the stone powder content and mud content of building aggregates in different specifications, and it has the characteristics of rich functions. In addition, the coarse aggregate uses a double-layer filter screen, which can further ensure the test accuracy. Because when the coarse aggregate rolls on the filter screen, its relatively large weight and edges may damage the filter hole shape of the upper filter screen, but the filter hole shape of the lower filter screen remains intact, so the test accuracy is ensured.
