Description

Technical Field

[0001] The utility model relates to the field of sand material mixing devices, in particular to a multi-layer sand material mixing system and a quartz sand processing system. Background Art

[0002] Existing sand generally needs to be mixed with colorants, but the colorants required for sand in each product are not the same. Therefore, the main product uses a larger amount of colored sand, while the secondary product uses a smaller amount of colored sand. However, since the mixing of sand and colorants used in the main products occupies the mixing system, the mixing of sand used in secondary products often requires the use of other mixing systems. The workshop needs to prepare multiple mixing systems, and a single mixing system cannot mix the primary color sand and the secondary color sand at the same time. At the same time, traditional workshops using multiple mixing systems often need to prepare multiple workers to feed, mix and discharge materials, resulting in low batching efficiency and high worker costs.

[0046] like Figure 1-3 , a multi-layer sand material mixing system, comprising: a top layer sand bin (1), a middle layer material receiving assembly (2) and a bottom layer material receiving assembly (3);

[0047] The top layer sand bin (1), the middle layer material receiving assembly (2) and the bottom layer material receiving assembly (3) are sequentially distributed from the upper layer to the lower layer; the middle layer material receiving assembly (2) comprises: a primary color stirring device (21) and a multi-color weighing device (22);

[0048] The input end of the primary color stirring device (21) is connected to one of the output ends of the top sand bin (1), and is used to receive the sand material stored in the top sand bin (1), and stir and mix the color material of the default color with the sand material;

[0049] The input end of the multi-color weighing device (22) is connected to one of the output ends of the top sand bin (1) and is used to receive and weigh sand materials and colorants of multiple colors.

[0050] The bottom layer material receiving assembly (3) comprises: a primary color material weighing device (31) and a multi-color mixing device (32);

[0051] The input end of the primary color weighing device (31) is connected to the output end of the primary color stirring device (21); the primary color weighing device (31) has a weighing function;

[0052] The input end of the multi-color mixing device (32) is connected to the output end of the multi-color weighing device (22) and is used to mix the sand material output by the multi-color weighing device (22) and the color materials of multiple colors.

[0053] The present invention provides a sand material mixing system, wherein a top layer sand bin (1), a middle layer material receiving assembly (2) and a bottom layer material receiving assembly (3) are sequentially arranged at different height layers, wherein the middle layer material receiving assembly (2) has the functions of mixing primary color sand materials and weighing multi-color sand materials, and the bottom layer material receiving assembly (3) has the functions of weighing primary color sand materials and mixing multi-color sand materials, so that large quantities of primary color sand materials and small quantities of multi-color sand materials can be prepared at the same time, thereby improving the efficiency of sand material color matching and greatly reducing the number of workers required for each layer, thereby solving the problems of low efficiency of multi-color sand material matching and high worker costs.

[0054] The top sand bin (1), the middle material receiving assembly (2) and the bottom material receiving assembly (3) of the present invention are arranged vertically, the top sand bin (1) is located above the middle material receiving assembly (2), and the middle material receiving assembly (2) is located above the bottom material receiving assembly (3); wherein the middle material receiving assembly (2) is provided with a primary color stirring device (21) and a multi-color weighing device (22); the primary color stirring device (21) has a stirring function, after receiving the sand material from the top sand bin (1), it can add a color material of a default color to mix with the sand material, since the color material of the default color is the primary color The color stirring device (21) is commonly used in coloring materials, so a larger device is used to mix more coloring materials and sand materials. Since the coloring materials do not need to be replaced during long-term use, there is no problem of coloring material residue affecting the coloring. At the same time, the multi-color weighing device (22) is arranged at the same height layer as the primary color stirring device (21), and is used to receive the sand materials in the top sand bin (1), and different coloring materials can be added to the multi-color weighing device (22). The multi-color weighing device (22) has a weighing function, which can weigh the added weight of different coloring materials so as to complete the mixing according to the coloring formula. When the primary color stirring device (21) completes the mixing, it can be output to the primary color weighing device (31). The primary color weighing device (31) weighs the continuously collected primary color sand material, and packs or transfers the raw sand material of a specific weight as needed, so that the sand material collection can be completed at the bottom layer; after the multi-color mixing device (32) collects the sand material mixture of a specific color formula, it will stir the sand material mixture to make the sand material and the color material mix completely, and then output the sand material of the specific color after mixing. In this way, this scheme can stagger the batching process of the primary color of the sand material with the batching process other than the primary color, and the primary color sand material can be mixed in large quantities and discharged in batches. The multi-color weighing device (22) can weigh multiple color materials according to the formula of a specific color, so that the large-scale primary color batching of the sand material and the small-scale multiple-color batching of the sand material are both available at the same time, and the batching of the primary color sand material will not be affected by the batching of other colors, thereby improving the batching efficiency of the sand material. Furthermore, the primary color stirring device (21) and the primary color weighing device (31) correspond to the batching of the primary color sand material, and the multi-color weighing device (22) and the multi-color mixing device (32) correspond to the batching of the multi-color sand material. Therefore, only one worker is required for each process of the raw sand material and the multi-color sand material, which can greatly reduce the number of workers required for each layer and solve the problem of high worker costs.
