Description

Technical Field

[0001] This utility model relates to the field of sand washing machines, and in particular to a reverse-thrust vortex sand washing machine. Background Technology

[0002] In numerous fields such as construction, mining, and water conservancy projects, sand and gravel serve as fundamental and crucial raw materials, and their cleanliness directly impacts the quality and safety of subsequent projects. To remove impurities such as mud and stone powder from sand and gravel and ensure they meet usage standards, vortex sand washing machines have emerged. Leveraging the application of water flow principles, they occupy a vital position in sand and gravel washing operations, becoming an indispensable key piece of equipment for improving sand and gravel quality, and are widely used in various scenarios requiring deep purification of sand and gravel.

[0003] Existing vortex sand washing machines typically use a main vortex generator as their core mechanical structure. Their technical principle involves a motor driving an impeller to rotate at high speed, creating a unidirectional vortex in the water within the washing chamber. Under the influence of this vortex, sand and gravel move in a circular motion with the water flow. Utilizing the density difference between sand and impurities, the less dense impurities are drawn towards the center of the vortex under centrifugal force and then discharged through a discharge port located in the central area. Meanwhile, the sand and gravel move towards the edge under the combined action of gravity and water flow thrust, completing the initial washing and separation process.

[0004] However, existing vortex sand washing machines, in actual operation, suffer from relatively uniform vortex intensity and distribution, failing to achieve a comprehensive and continuous three-dimensional scouring effect on sand and gravel. When sand and gravel enter the washing chamber, some, due to their greater weight, quickly settle to the bottom of the chamber in areas where the vortex effect weakens. This settled sand and gravel is difficult to thoroughly clean, creating numerous cleaning dead zones. This results in incomplete separation of impurities from the sand and gravel, severely impacting the cleaning quality. Therefore, a reverse-thrust vortex sand washing machine is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a reverse-push vortex sand washing machine, which aims to improve the problem that it is impossible to form a comprehensive and continuous three-dimensional scouring effect on sand and gravel, thus creating a large number of cleaning dead corners, resulting in incomplete separation of impurities from sand and gravel, which seriously affects the cleaning quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reverse-thrust vortex sand washing machine includes a vortex cleaning chamber, a discharge port on one side of the vortex cleaning chamber, a feed port on the other side of the vortex cleaning chamber, multiple multi-stage vortex generators inside the vortex cleaning chamber, multiple ultrasonic waves fixedly connected to the top of the vortex cleaning chamber, the bottom ends of the multiple ultrasonic waves extending into the interior of the vortex cleaning chamber, multiple reverse-thrust emitters at the bottom of the vortex cleaning chamber, reverse-thrust components at the bottom of the multiple reverse-thrust emitters, and drive components at the top of the multiple multi-stage vortex generators.

[0008] As a further description of the above technical solution:

[0009] The discharge port is connected to the fine sand recovery module, which is used to recover fine sand from wastewater and recycle water resources.

[0010] As a further description of the above technical solution:

[0011] The thrust reverser assembly includes multiple thrust reverser chambers, with the bottoms of the multiple thrust reverser launchers connected to the thrust reverser chambers, and the outer walls of the multiple thrust reverser chambers fixedly connected to the bottom of the vortex cleaning chamber.

[0012] As a further description of the above technical solution:

[0013] Each of the aforementioned reaction thrust chambers has an inlet at its bottom, which provides a channel for water to enter the interior of the reaction thrust chamber.

[0014] As a further description of the above technical solution:

[0015] The drive assembly includes multiple motors, each of which is located on top of the multi-stage eddy current generator.

[0016] As a further description of the above technical solution:

[0017] Each of the motor output terminals is fixedly connected to a speed reducer, and the bottoms of the multiple speed reducers are fixedly connected to the top of the vortex cleaning chamber.

[0018] As a further description of the above technical solution:

[0019] The top of the multi-stage eddy current generator penetrates through the eddy current cleaning chamber and extends into the interior of the reducer.

[0020] This utility model has the following beneficial effects:

[0021] This invention utilizes a synergistic design of reverse-flow water and multi-stage vortex to fully suspend and three-dimensionally flush sand and gravel within the cleaning chamber. This effectively solves the technical problems of traditional equipment, such as numerous cleaning dead zones and incomplete separation of impurities from sand and gravel due to rapid material settling. Simultaneously, the ultrasonic assistance enhances the removal of microscopic contaminants from the sand and gravel surface, significantly improving the cleanliness of the finished product. While increasing cleaning efficiency, it drastically reduces fine sand loss and water consumption, achieving a comprehensive advantage of high efficiency, energy saving, environmental friendliness, durability, and high automation.

[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 Figures 1-3This utility model provides an embodiment of a reverse-thrust vortex sand washing machine, comprising a vortex cleaning chamber 6. A discharge port 1 is provided on one side of the vortex cleaning chamber 6, which is used to discharge impurities floating during the washing process with the water flow, solving the problem of easy clogging in traditional impurity discharge channels. A feed port 5 is provided on the other side of the vortex cleaning chamber 6, which is used to guide sand and gravel materials into the equipment for cleaning. Multiple multi-stage vortex generators 7 are installed inside the vortex cleaning chamber 6. The multi-stage vortex generators 7, in conjunction with the top drive assembly, rotate at high speed. Their internal spiral guide plates and inclined impellers can generate strong and complex multi-directional vortices, achieving deep cleaning of sand and gravel materials through thorough agitation and high-frequency friction washing. For enhanced cleaning, multiple ultrasonic waves 2 are fixedly connected to the top of the vortex cleaning chamber 6. These ultrasonic waves 2 emit high-frequency vibrations into the water, generating a powerful microscopic physical stripping effect through cavitation, thus enhancing the final cleaning effect on microscopic contaminants on the surface of sand and gravel. The bottom ends of the multiple ultrasonic waves 2 extend into the interior of the vortex cleaning chamber 6. Multiple thrust emitters 10 are installed at the bottom of the vortex cleaning chamber 6. These thrust emitters 10, in conjunction with the thrust assembly at the bottom, spray high-pressure water from bottom to top to form a reverse impact water curtain, achieving the effect of instantly stripping impurities from the surface of sand and gravel and causing them to float. The thrust assembly at the bottom of the multiple thrust emitters 10 is the core structure for generating the reverse high-pressure water flow, which counteracts the falling sand and gravel material. This effectively solves the problem of unclear separation caused by the rapid settling of sand and impurities together in traditional equipment. Multiple multi-stage eddy current generators 7 are equipped with drive components on top, which provide stable and powerful rotational power to the multi-stage eddy current generators 7, serving as the core power source for multi-directional eddy current cleaning. The discharge port 1 is connected to a fine sand recovery module, which treats the discharged wastewater, efficiently recovering lost fine sand and purifying and recycling water resources, achieving the beneficial effects of saving water resources and reducing production losses. The reverse thrust assembly includes multiple reverse thrust chambers 8, which collect and pressurize the water flow entering from the inlet 9, providing a continuous and stable high-pressure water source for the reverse thrust launcher 10. Multiple thrust reverser launchers 10 are connected at their bottoms to the thrust reverser chambers 8. The outer walls of the multiple thrust reverser chambers 8 are fixedly connected to the bottom of the eddy current cleaning chamber 6. Each thrust reverser chamber 8 has an inlet 9 at its bottom, which provides a channel for water to enter the interior of the thrust reverser chamber 8. The drive assembly includes multiple motors 3, each of which is located at the top of the multi-stage eddy current generator 7. Each motor 3 has a reducer 4 fixedly connected to its output end. The reducer 4 is used to adjust the high speed of the motor 3 to a high torque and low speed suitable for the operation of the multi-stage eddy current generator 7. The bottoms of the multiple reducers 4 are fixedly connected to the top of the eddy current cleaning chamber 6. The top of the multi-stage eddy current generator 7 penetrates the eddy current cleaning chamber 6 and extends into the interior of the reducer 4.

[0029] Working Principle: During equipment operation, sand and gravel enter the vortex cleaning chamber 6 through the feed inlet 5. Simultaneously, water flows through the feed inlet 9 into the reaction thrust chamber 8 at the bottom of the equipment, forming a high-pressure reverse water flow from bottom to top via multiple reverse thrust ejectors 10. This powerful reverse thrust water flow counteracts the falling sand and gravel, effectively solving the problem of incomplete separation caused by the rapid settling of sand and gravel with impurities in traditional equipment. It can instantly peel off lighter impurities such as mud attached to the surface of the sand and gravel and push them upwards. During this process, the multi-stage vortex generator 7, driven by the motor 3 and the reducer 4, rotates at high speed in the vortex cleaning chamber 6. The spiral guide plate and inclined impeller can generate a strong and complex multi-directional vortex. The continuous stirring effect of this vortex, combined with the upward reverse thrust water flow, lifts the sand and gravel into the vortex cleaning chamber. The washing chamber 6 is suspended in a state where high-frequency friction and scouring between sand and gravel, and between sand and gravel and water flow, enhances the deep cleaning effect on stubborn impurities and effectively solves the problem of material settling in the bottom corners of traditional sand washing machines, forming cleaning dead corners. To achieve ultimate cleanliness, the ultrasonic device 2 located above the equipment emits high-frequency vibrations into the water, generating countless microbubbles through cavitation effect. This powerful micro-physical peeling action further removes micro-dirt from the surface of the sand and gravel, enhancing the cleanliness of the final product. After the above-mentioned multi-stage synergistic cleaning, impurities are discharged through the discharge port 1 with the upper water flow, solving the problem of easy clogging of traditional impurity discharge channels. The wastewater then enters the subsequent fine sand recovery module for treatment, realizing the recycling of water resources and recovering lost fine sand, achieving the beneficial effects of saving water resources and reducing production losses.

[0030] 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.
