Description

Technical Field

[0001] This utility model relates to the field of sand washing machine technology, and in particular to a high-efficiency sand washing machine. Background Technology

[0002] Sand washing machines are commonly used cleaning equipment in sand and gravel production, used to remove impurities such as mud and stone powder from the surface of sand and gravel. They effectively improve the cleanliness and quality of sand and gravel, and are widely used in construction, road construction, and other fields, serving as key equipment for ensuring the quality of sand and gravel.

[0003] Traditional sand washing uses wheel-type or spiral-type washing machines, requiring one or more machines in combination to clean the material. However, traditional sand washing equipment cannot clean impurities in the gaps between the raw materials; it only cleans impurities on the surface. Meanwhile, the sand washing industry has increasingly higher requirements for the cleanliness and hardness of the finished product, which existing equipment cannot meet. Furthermore, traditional equipment is bulky and complex in structure, not only occupying a lot of space but also requiring a lot of manpower, material resources, and time to build the foundation during installation. Therefore, a high-efficiency sand washing machine is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency sand washing machine, which aims to improve the problems of traditional sand washing machines having high equipment requirements, poor wear resistance, and substandard sand cleanliness.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a high-efficiency sand washing machine, including a frame 1, which is the supporting structure of the entire sand washing machine and is used to stably support the various components. A feed hopper 2 is installed at one end of the top of the frame 1. The feed hopper 2 is funnel-shaped and is used to receive the mixed materials to be washed, guiding the materials smoothly into subsequent processing stages. A scrubbing machine 3 is installed on one side of the top of the frame 1 to scrub the materials and remove surface and crevices impurities. A hydrocyclone 7 is installed in the middle of the top of the frame 1. The hydrocyclone 7 uses centrifugal force to separate and wash the materials, achieving mud-water separation. A dewatering screen 8 is installed on the other side of the top of the frame 1. This is a linear vibrating screen that uses high-frequency vibration to dewater the materials and improve the dryness of the sand. A discharge hopper 9 is installed at the other end of the top of the frame 1 to collect the final product. The high-quality sand after washing and dewatering is discharged from the equipment. A water tank 10 is installed on one side of the bottom of the frame 1. The water tank 10 is used to store the washing water and collect the separated mud water to provide a water source for the circulating washing. A chute 12 is installed at one end of the scrubbing machine 3, and one end of the chute 12 is connected to the inside of the water tank 10. The chute 12 is an inclined trough structure that transports the material processed by the scrubbing machine 3 to the water tank 10. A slurry pump 11 is installed in the middle of the bottom of the inner wall of the frame 1, and the input end of the slurry pump 11 is fixedly connected to the bottom of the water tank 10. The slurry pump 11 is used to extract the material at the bottom of the water tank 10. The output end of the slurry pump 11 is fixedly connected to the feed pipe 5, and the top end of the feed pipe 5 is connected to the top of the hydrocyclone 7. The feed pipe 5 provides a conveying channel for the material to flow from the slurry pump 11 to the hydrocyclone 7.

[0029] Reference Figure 1 A ladder 13 is installed at one end of the frame 1 near the feed hopper 2. The ladder 13 makes it convenient for workers to climb to the top of the frame 1 to carry out inspection and maintenance operations.

[0030] Reference Figure 1 Platform handrails 4 are installed on both sides of the top of the frame 1. The platform handrails 4 provide safety protection for workers when working on the top of the equipment to prevent accidental falls.

[0031] Reference Figure 1 The bottom of the feed hopper 2 is connected to the interior of the scrubbing machine 3, so that the mixed material can smoothly enter the scrubbing machine 3 from the feed hopper 2 for cleaning.

[0032] Reference Figure 1 The bottom of the hydrocyclone 7 is connected to the dewatering screen 8, so that the material flowing under the hydrocyclone 7 can enter the dewatering screen 8 for the next dewatering operation.

[0033] Reference Figure 1 The bottom of the dewatering screen 8 is connected to the inside of the water tank 10, so that the wastewater under the screen can flow back to the water tank 10, realizing the recycling of water resources.

[0034] Reference Figure 1 One end of the dewatering screen 8 is connected to the discharge hopper 9, so that the dewatered fine sand can be conveyed from the dewatering screen 8 to the discharge hopper 9 for discharge.

[0035] Reference Figure 1 The top of the hydrocyclone 7 is equipped with a return water pipe 6, and the bottom end of the return water pipe 6 is connected to the water tank 10. The return water pipe 6 transports the overflow material of the hydrocyclone 7 back to the water tank 10 for circulation cleaning and replenishing the water volume of the water tank 10.

[0036] Working principle: The dewatering screen 8 is a linear vibrating screen. The mixed material first enters the scrubbing machine 3 for thorough scrubbing to remove impurities from the surface and crevices of the sand. Then, it enters the under-screen water tank 10 through the chute 12, and is then sent to the hydrocyclone 7 by the slurry pump 11. Under the action of centrifugal force, the material is washed and the water is controlled, achieving the effect of separating sand from mud and water. The underflow material of the hydrocyclone 7 enters the coarse sand dewatering zone of the dewatering screen 8 for dewatering, while the overflow material enters the water tank 10 through the return water pipe 6 for circulation cleaning and water replenishment, thereby achieving efficient sand washing. Finally, the high-quality sand is discharged from the discharge hopper 9. The transmission structure of the scrubbing machine 3 is designed with a reducer directly connected to the scrubbing shaft, which is more efficient than belt drive. The operation is more stable, eliminating the need for large and small pulleys and belts, reducing vulnerable parts and lowering the failure rate. At the same time, the cleaning effect is better. The motor installation method is changed from the traditional side direct connection, which greatly reduces the space occupied in the width direction. The space above the vibrating screen is used to install the motor, and the spray bracket can also be combined to form a unified design. The box-type vibrator has strong synchronization, stable operation, and simple adjustment. The excitation force and direction angle can be adjusted directly by disassembling or replacing the assembly weights. The hydrocyclone 7 uses 95 wear-resistant ceramic as the inner lining material. This ceramic has excellent hardness and wear resistance. When dealing with high-speed flowing sand and gravel, the ceramic lining can effectively resist erosion, greatly extending the service life of the hydrocyclone 7.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
