Description

Technical Field

[0002] With the increasing number of large-scale mines in China, many high-energy-consuming and low-output equipment are gradually facing obsolescence. In dry-process refined sand production lines, the finished sand often has a high powder content, generating significant dust during its descent, and segregation is unavoidable (separation of coarse and fine particles, resulting in uneven distribution). Furthermore, the maximum processing capacity of existing wet mixing machines is typically 150t / h-200t / h. For large-capacity sand production lines exceeding 300t / h, a single wet mixing machine is insufficient, while using two machines is space-consuming, increases maintenance points, and raises project investment. Therefore, to meet current market demands, a high-flow-rate, low-energy-consumption wet mixing machine needs to be developed. Utility Model Content

[0025] <Example>

[0026] See Figure 1 This embodiment provides a vertical mixing wet machine for a sand making production system, which includes an outer shell 3, an inner cylinder, a feeding structure 1, a water circuit assembly 2, a first impeller group 4, a second impeller group 7, a lower drag wheel group 8, and a motor 9.

[0027] The outer casing 3 is perpendicular to the ground, and the feeding structure 1 is located above the outer casing 3. The inlet diameter of the feeding structure 1 is smaller than the inner diameter of the inner cylinder, and the lower end of the feeding structure 1 is located inside the inner cylinder. A flange is provided on the top of the outer casing 3, and a flange is also provided on the feeding structure 1. The feeding structure 1 and the outer casing 3 are connected by the flange and bolts (in...). Figure 1 (As shown in position 11) It is detachably connected. The bottom of the outer casing 3 is provided with a discharge port. The feeding structure 1 is fixed by bolt connection, which is convenient for disassembly and easy replacement of the internal parts of the outer casing.

[0028] The inner cylinder is located inside the outer shell 3 and is vertically positioned to the ground. The inner cylinder consists of multiple inner cylinder units 5 arranged from top to bottom, and multiple grate plates 6 connecting the upper and lower inner cylinder units 5. The inner cylinder unit 5 is cylindrical; in this embodiment, the inner cylinder includes four inner cylinder units 5. (See [reference]). Figure 3 The lower inner cylinder unit 5 has several triangular plates 53 welded and fixed to its inner side at its lower end to increase strength. Bolt holes are provided on the edge of the grate plate 6. The two inner cylinder units 5, connected vertically, are each equipped with a flange. Bolts pass through the flange bolt holes of the upper inner cylinder unit 5, the bolt holes of the grate plate 6, and the flange bolt holes of the lower inner cylinder unit 5 for connection and fixation. The inner cylinder unit 5 and the grate plate 6 together form the drum assembly of the mixing machine. The motor 9 is located on the outside of the outer casing 3. The motor 9 provides power, driving the drum assembly to rotate and perform work through a transmission mechanism. The transmission mechanism adopts a conventional chain drive mechanism, and its transmission method is the same as that in existing mixing machines where the motor drives the drum rotation through a transmission mechanism; therefore, it will not be described in detail here.

[0029] The first set of stop wheels 4 and the second set of stop wheels 7 are respectively installed at the upper and middle positions inside the outer casing 3. The first set of stop wheels 4 is used to limit the upper end of the outer wall of the inner cylinder. There are multiple sets of first set of stop wheels 4, which are evenly distributed in a ring array around the inner cylinder. The second set of stop wheels 7 is used to limit the middle of the outer wall of the inner cylinder. There are multiple sets of second set of stop wheels 7, which are evenly distributed in a ring array around the inner cylinder.

[0030] The first gear group 4 and the second gear group 7 have the same structure. See also Figure 2 The retaining wheel assembly structure includes a shaft mounting support 41, which is bolted to a flange platform 31 on the side wall of the outer casing 3. A vertical shaft 42 is mounted on the shaft mounting support 41, and a retaining wheel is mounted on the vertical shaft 42. The retaining wheel includes a retaining wheel body 431, with a bearing 432 embedded in the center of the retaining wheel body, allowing the retaining wheel to rotate smoothly around the vertical shaft 42. A protective layer 433 is provided on the outer circumferential surface of the retaining wheel body. Since the retaining wheel body and the inner cylinder are made of metal, and metal is hard, prolonged contact and friction between the two during the rotation of the inner cylinder can easily damage the inner cylinder. Using a relatively soft material such as rubber or plastic as a protective layer can provide a buffering and protective function. When the inner cylinder is stationary, there is a small gap between the protective layer of the retaining wheel and the outer circumference of the inner cylinder. The specific gap size can be set according to the actual situation. When the inner cylinder rotates, due to its large mass, it is easy to deviate horizontally during the rotation. When it deviates, the retaining wheel will contact the outer circumference of the inner cylinder, limiting its continued deviation and playing a limiting role. When the inner cylinder rotates in contact with the retaining wheel, the retaining wheel will also rotate around the vertical axis 42, which will not hinder the rotation of the inner cylinder.

[0031] The lower roller assembly 8 is installed on the bottom inner side of the outer casing 3. Multiple lower roller assemblies 8 are arranged in a circular array around the inner cylinder, providing support for the lower end of the inner cylinder's outer wall. (See also...) Figure 3 The lower towing wheel assembly 8 includes a shaft mounting base 81, which is fixed to the bottom of the outer casing 3. A horizontal shaft 82 is mounted on the shaft mounting base 81, and a towing wheel is mounted on the horizontal shaft 82. The towing wheel includes a towing wheel body 831, with a bearing 832 embedded in the center of the towing wheel body, allowing the towing wheel to rotate smoothly around the horizontal shaft 82. The towing wheel body 831 is made of metal. A protective layer 833 is covered on the outer circumference of the towing wheel body 831, and the material of the protective layer 833 is the same as that of the protective layer 433 of the retaining wheel. The lower end of the inner cylinder made of metal is provided with a metal annular edge 51, a reinforcing plate 52 is welded above the annular edge 51, and an annular track groove is provided below the annular edge 51. The towing wheel is located in the annular track groove. When the inner cylinder is in a stationary state or a rotating state, the lower surface of the annular edge 51 is in contact with the protective layer 833 of the towing wheel. When the inner cylinder is rotating, the annular edge 51 of the inner cylinder is in sliding contact with the protective layer 433 of the towing wheel, which will not hinder the rotation of the inner cylinder.

[0032] Water circuit assembly 2 includes a vertical water circuit pipe installed in the inner cylinder. Multiple water spray holes are opened on the vertical water circuit pipe from top to bottom. The vertical water circuit pipe is connected to a horizontal water circuit pipe, which is connected to an external water supply system (not shown in the figure). A booster pump (not shown in the figure) is installed on the horizontal water circuit pipe.

[0033] The vertical mixing machine used in the sand making production system of this embodiment works as follows: After the material enters the inner cylinder from the feeding structure 1, the material is dispersed by the rotating inner cylinder unit 5 and the grate plate 6 during the falling process. Water is sprayed out by the water circuit component 2 to adjust the humidity of the mixing, so that the material does not separate when it comes out, achieving the purpose of no water spillage and no dust. Finally, the mixed material comes out from the discharge port at the bottom.

[0034] In this embodiment, the vertical mixing drum assembly of the sand production system rotates perpendicular to the ground. The power of a single vertical mixing drum is 7.5KW, and the material throughput is 300-400t / h.

[0035] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
