Description

Technical Field

[0001] The invention relates to the technical field of sand washers, and in particular to a spiral sand washing machine with adjustable angle. Background Art

[0002] As an important equipment for modern sand and gravel cleaning and grading, spiral sand washing machine is widely used in construction sites, sand and gravel plants, mining, concrete mixing plants and other fields. It is mainly used to remove impurities in sand and gravel and improve the purity and quality of finished sand. However, the fixed angle design of traditional spiral sand washing machine has certain limitations in practical applications. Due to the large changes in the types, particle sizes, impurity content and working conditions of sand and gravel, it is difficult for fixed-angle sand washing machines to take into account both cleaning effect and energy efficiency, which limits the scope of application and operation flexibility of the equipment. The angle-adjustable spiral sand washing machine introduces an adjustment mechanism in the equipment structure so that the working angle of the sand washing machine can be adjusted according to different application requirements. By adjusting the working angle, the following optimizations can be achieved: when cleaning more viscous or high-impurity sand and gravel, the inclination angle can be increased to extend the cleaning path of sand and gravel in the water tank and improve the cleaning effect; when processing sand and gravel with higher cleanliness, the inclination angle can be appropriately reduced to improve processing efficiency and reduce energy consumption. In addition, the adjustable angle design can also adapt to the special needs of different industries or work sites. For example, when constructing on a site with a large slope, the angle can be adjusted to achieve smooth sand and gravel transportation and cleaning operations; There are still the following defects in specific use: 1. In places with high stacking density, it is difficult for airflow or heat to penetrate, and the moisture in the internal sand and gravel cannot be fully evaporated. The sand and gravel that are not completely dried may affect the strength, stability and bonding properties of the material during subsequent processing or use. At the same time, uneven drying of sand and gravel will lead to inconsistent product performance, affecting the overall project quality, increasing energy consumption, directly increasing production costs, and reducing economic benefits.

[0003] 2. In addition, the edges and corners in the sand and gravel will cause high-intensity friction and impact on the surface of the equipment during the mixing, transportation and processing, resulting in rapid wear of the surface of the components. At the same time, due to the wear caused by the edges and corners, the equipment components need to be replaced frequently, which not only increases the material cost, but also causes equipment downtime and production interruption. Wear will change the surface characteristics and operating status of the equipment. For example, when the blade shape of the spiral sand washing machine is destroyed, the efficiency of transportation or mixing decreases, thereby increasing energy consumption.

Applying them on the surface of sand and gravel can help improve the durability and anti-aging ability of sand and gravel, which is especially suitable for projects in certain harsh environments.

[0023] The complete working principle and steps of the above embodiment are as follows: Initial limitation: 1. Feeding stage Before operation, the sand and gravel to be processed are evenly transported to the water tank 13 of the spiral sand washing machine body 1 through the feeding device. After entering the equipment, the sand and gravel are mixed with the water in the water tank 13 to form a suspension of sand and gravel and water. In this process, the water tank 13 plays the role of carrying water and sand and gravel, creating basic conditions for cleaning and separation. At the same time, the depth and width of the water tank 13 ensure that the deposition and movement process of sand and gravel in the water tank 13 can proceed smoothly, avoiding the problem of blockage or uneven accumulation of sand and gravel.

[0024] 2. Driving and stirring The driving device 12 provides power and drives the spiral body 11 to rotate through the transmission shaft. The rotation of the spiral body 11 causes the sand and gravel to be stirred and tumbled in the water tank 13. The design of the spiral blade effectively stirs, pushes and rubs the sand and gravel through the spiral curve, thereby causing the dirt, dust and other impurities on the surface of the sand and gravel to gradually fall off. At this stage, the clean water in the water tank 13 flows through the gaps between the sand and gravel, playing a lubricating and flushing role, further enhancing the cleaning effect.

[0025] The rotation speed of the spiral body 11 is precisely designed to ensure the cleaning intensity while avoiding damage caused by excessive friction between the sand and gravel. The angle and size of the spiral blades are optimized to meet the cleaning needs of different types of sand and gravel, while reducing the accumulation of sand and gravel during the cleaning process.

[0026] 3. Cleaning and separation As the gravel gradually moves toward the outlet in the water tank 13, the clean water in the water tank 13 continuously washes the surface of the gravel. Due to their low density, soil and impurities will move to the upper part of the water tank 13 with the water flow and be discharged through the overflow port of the water tank 13. The stirring of the spiral 11 makes the lighter impurities suspended in the water, so that they are effectively separated. After repeated washing and stirring, the surface of the gravel becomes clean, achieving the desired cleaning effect.

[0027] During the cleaning process, the structural design at the bottom of the water tank 13 ensures that larger sand and gravel can be stably pushed forward, while smaller particles and sediments are diverted and discharged to avoid clogging or wear of the equipment. Through this process, water, sand and gravel and impurities are effectively separated, thereby achieving efficient utilization of resources and stable operation of the equipment.

[0028] 4. Discharging stage The cleaned sand and gravel are gradually pushed to the outlet of the water tank 13 along the moving direction of the spiral body 11. In this process, the driving force of the spiral blades enables the sand and gravel to overcome the resistance of the water and be transported out of the water tank 13. Since the sand and gravel have been fully cleaned, the sand and gravel at the outlet are of high quality, and there is almost no soil and impurities on the surface, which meets the quality requirements of construction, roads and other projects for sand and gravel materials.

[0029] 5. Water resource recycling The main body 1 of the spiral sand washing machine uses a large amount of water during the cleaning process, but at the same time has good water resource management capabilities. The water discharged through the overflow can be precipitated and filtered through the sedimentation tank to separate the silt in the water, and the clear water after precipitation can be recycled again. This design effectively reduces the operating cost of the equipment and responds to the demand of modern industry for energy conservation and environmental protection; When using: Cross drying mechanism for dynamically breaking up sand and gravel accumulation into a more even distribution 2 steps: like Figure 3 to Figure 4As shown, when the operator uniformly transports the sand and gravel to be processed into the water tank 13 of the spiral sand washing machine body 1 through the feeding device, the sand and gravel will first fall into the placement tank plate 21 fixedly connected to the inner wall of the water tank 13, and then the operator starts the control switch installed on the outer wall of the telescopic cylinder 23 to drive one end of the telescopic cylinder 23 to retract to one side, so that the card plate 24 fixedly connected to one end of the telescopic cylinder 23 will move synchronously with the retraction of the telescopic cylinder 23 to one side, so that the card plate 24 moves on the outer wall of the fixed shaft 25. The lower swing rod 27 and the upper swing rod 28 connected to the outer wall will be deflected and spread out in opposite directions in turn, and the deflection and spread of the lower swing rod 27 and the upper swing rod 28 in opposite directions will push the upper oblique rod 29 and the lower oblique rod 210 to deflect and gather in the same direction in turn, so that the movement of the card plate 24 pushes the upper oblique rod 29 and the lower oblique rod 210 to deflect and gather in the same direction in turn, so that the drying ball 211 fixedly connected to the bottom end of the card plate 24 will destroy the sand and gravel falling into the placement slot plate 21 The hierarchical structure of the stacking forms a looser stacking; The three steps of the edge grinding mechanism used to reduce the sharpness of the edges and the friction between the sand and the gravel: like Figures 5 and 6 As shown, when the card plate 24 moves on the outer wall of the fixed shaft 25, it will synchronously drive the oblique tooth plate 212 fixedly connected at one end thereof to move, and then the transverse bevel gear 33 meshing with the outer wall of the oblique tooth plate 212 will rotate synchronously, and the rotation of the transverse bevel gear 33 will also drive the longitudinal bevel gear 32 meshing with its outer wall to rotate, so that the cam 34 fixedly connected to the outer wall of one side of the longitudinal bevel gear 32 will rotate, and the turntable 35 fixedly connected to the outer wall of one side of the cam 34 will also rotate with the cam 34, so that the double-headed buckle 36 eccentrically fixedly connected to the outer wall of one side of the turntable 35 will rotate with the rotation of the turntable 35, so that the double-headed buckle 36 fixedly connected to the outer wall of one side of the turntable 35 will rotate with the rotation of the turntable 35. The push plate 37 on the outer wall at one end of the double-headed buckle 36 will push and stir the sand and gravel placed inside the placement slot plate 21 as the double-headed buckle 36 rotates. Secondly, the rotation of the cam 34 will cause the raised part set at its bottom end to push the tilting rod 38 to shake and deflect up and down. The up and down shaking and deflection of the tilting rod 38 will cause the support block 39 fixedly connected at one end to push the resisting extrusion column 310 to move up and down. In this way, the wedge-shaped rod 311 fixedly connected to the outer wall of the support block 39 will deflect left and right on the inner wall of the placement slot plate 21. Therefore, the grinding disc 312 fixedly connected to the outer wall of one side of the wedge-shaped rod 311 will also realize friction grinding of the corners of the sand and gravel inside the placement slot plate 21 as the wedge-shaped rod 311 deflects left and right.

[0030] Powder attachment mechanism for increasing the roughness of the gravel surface and thus improving the adhesion of the gravel 4 steps: like Figures 7 and 8As shown, when the tilting rod 38 shakes and deflects up and down, the central shaft ring 313 fixedly connected to the center of its outer wall will rotate synchronously, and then the connecting rod 41 rotatably connected at one end thereof will rotate, so that the square block 42 fixedly connected to the outer wall of one end of the connecting rod 41 will slide in the arc groove opened inside the arc rod 43 as the connecting rod 41 rotates, and at the same time the square block 42 will also push the arc rod 43 to move horizontally left and right, so that the double-headed plate shaft 44 fixedly connected to the outer wall of the bottom end of the arc rod 43 will also move horizontally, thereby the brush plate 45 fixedly connected to the outer wall of one side of the double-headed plate shaft 44 will realize the lateral movement of the double-headed plate shaft 44 to realize the powder accumulated at the bottom of the sand and gravel to be applied to the sand and gravel surface again; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
