Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mud and sand processing, in particular to a mud removal and sand washing device. Background Art
[0002] Sediment treatment is of great significance in the fields of environmental protection, engineering construction and resource utilization. It usually refers to the removal and treatment process of sediment, mud and other particles in water or soil, and is widely used in sewage treatment, river dredging, debris flow prevention and control, etc.
[0003] Therefore, a desludging and sand washing device is very necessary. In actual applications, the existing sand washing machine can effectively clean the impurities in the sand and gravel, but due to the limitations of its treatment method and equipment design, the washed wastewater still contains a large number of fine sand particles. These fine sand particles are usually discharged with the sewage, resulting in a waste of raw materials. Specifically, this situation has the following problems:
[0004] Raw material loss: During the sand washing process, the sand that should have been recycled is discharged with the water flow, resulting in the waste of some raw materials. Especially in areas with tight sand and gravel resources, this waste is more prominent, which will increase production costs and affect the sustainable use of resources.
[0005] Increased difficulty in sewage treatment: Fine sand particles in the water during the sand washing process will not only increase the turbidity of the sewage, but also make water treatment more difficult. Fine sand in sewage will cause water pollution, increase the burden on water treatment facilities, and may even clog pipes and equipment, affecting the subsequent water purification process.
[0006] Environmental pollution: If the wastewater containing fine sand generated during the sand washing process is not treated promptly and effectively, the fine sand particles will enter the nearby water or soil, causing water pollution and soil quality degradation. This will not only affect the ecological balance of the water body, but may also have an adverse effect on the growth of surrounding plants and animals.
[0007] Inefficiency: The existing sand washing equipment has low recovery efficiency and cannot completely recover the sand in the water, resulting in a waste of resources in the washing and screening process. In order to improve the recovery rate of raw materials, more energy and water resources may need to be invested, thereby increasing production costs and reducing overall economic benefits.
[0008] Therefore, how to reduce the loss of fine sand during the sand washing process and improve the recovery rate of raw materials has become an important issue in the design and operation of sand washing equipment. Utility Model Content

[0025] Embodiment 1: The ultrasonic sand washing structure includes an ultrasonic generator 8, which is arranged outside the upper box body 1. A plurality of ultrasonic vibrators 9 are installed on the upper inner side of the upper box body 1. The ultrasonic vibrators 9 are electrically connected to the ultrasonic generator 8. A first filter screen 10 is installed on the lower inner side of the upper box body 1. The ultrasonic vibrators 9 are inserted into the first filter screen 10.
[0026] The drain pipe 5, the sand outlet 6 and the sewage outlet 7 are all provided with valves;
[0027] Specifically, in the first embodiment, the core of the sand washing device is an ultrasonic sand washing structure, and its working principle is as follows:
[0028] Ultrasonic excitation: The ultrasonic generator 8 is located outside the upper box 1, and excites the built-in ultrasonic vibrator 9 through electrical connection to generate high-frequency ultrasonic vibrations. These vibrations are transmitted to the sand and gravel materials in the upper box 1, and by generating tiny bubbles, the purpose of cleaning and removing impurities attached to the surface of the materials is achieved.
[0029] Fine particle removal: Ultrasonic vibration can effectively shake off the dirt, oil, fine impurities, etc. on the surface of sand and gravel. After vibration, these impurities will be separated from the sand and gravel particles and guided into the lower box 2 by falling.
[0030] Filtration and reflux: A first filter screen 10 is installed on the lower side of the upper housing 1. Clean water is continuously sucked into the upper housing 1 by the water pump 4 to flush the mud and sand in the first filter screen 10. Impurities generated by the vibrating ultrasonic wave will pass through the filter screen through the action of the vibrating rod. The cleaned sand body will remain in the first filter screen 10 for collection, while the fine sand particles and sewage that cannot be cleaned will continue to be discharged into the lower housing 2 through the drain pipe 5 under the action of the water flow.
[0031] Sewage collection: The sewage treated by ultrasonic wave is guided to the lower box body 2 through the drainage pipe 5 arranged on the upper box body 1, and the sand remaining in the sewage is retained by the centrifugal sand washing structure and discharged from the sewage outlet 7, so as to achieve the effect of recycling materials.
[0032] In this way, the device can effectively remove fine impurities on the surface of sand particles and in them, improving the sand washing efficiency and the cleanliness of the raw materials.
[0033] Embodiment 2: The centrifugal sand washing structure includes a pair of partitions 11, which are symmetrically arranged on the left and right sides of the lower box body 2. A second filter screen 19 is embedded on the partitions 11. A pair of rotating rods 12 are arranged between the partitions 11. The rotating rods 12 are rotatably connected to the lower box body 2. The lower shaft end of the rotating rod 12 passes through the lower box body 2. A toothed disc 13 is installed at the lower end of the rotating rod 12. A chain is arranged between the toothed discs 13 on both sides. A plurality of blades 14 are arranged on the outer annular surface of the rotating rod 12, and a second bevel gear 15 is installed on the lower side of one of the rotating rods 12. A motor 16 is installed on the lower side of the lower box body 2. A first bevel gear 17 is installed on the rotating end of the motor 16, and the first bevel gear 17 is meshed and connected with the second bevel gear 15.
[0034] Specifically, in the second embodiment, the working principle of the sand washing device focuses on the centrifugal sand washing structure and the sewage recovery function, and the specific process is as follows:
[0035] Sand introduction and preliminary cleaning: During the sand washing process, sand enters the lower box 2 through the feed port 3 of the upper box 1. The water pump 4 continuously draws clean water, and the sand and impurities are brought into the lower box 2 through the water flow, and are initially filtered through the first filter screen 10 of the upper box 1. Large impurities are blocked by the filter screen, and clean water and fine sand flow into the lower box 2.
[0036] Centrifugal separation and cleaning: The sand particles entering the lower box 2 are further cleaned by the centrifugal sand washing structure. The rotating rod 12 inside the lower box 2 drives the blades 14 on the partition 11 to rotate at high speed, generating a strong centrifugal force to promote the separation of the sand particles from the water flow. Through this process, most of the silt and fine impurities are thrown out and further filtered through the second filter 19.
[0037] Residual fine sand separation: Through centrifugal force, the fine sand particles that have not been completely cleaned are separated and left to concentrate at the bottom of the lower box 2. The cleaned water flow is discharged through the sewage outlet 7 of the lower box 2.
[0038] Wastewater recovery and material recovery: The water after centrifugal sand washing contains some fine sand particles, which are guided to the wastewater recovery area of the lower box 2 through the drain pipe 5. In this area, the fine sand particles are effectively recovered through centrifugal separation, reducing the waste of raw materials. The clean water is discharged, which plays a dual role of wastewater recovery and material recovery.
[0039] Embodiment 3: The lower wall of the lower box body 2 located between the partitions 11 on both sides is in the form of a lower cone, and the sand outlet 6 is located at the center of the lower cone.
[0040] A plurality of blades 14 are plate-shaped and arc-shaped. The blades 14 of different shapes are cross-distributed on the rotating rod 12 . The blades 14 of arc-shaped have a curvature pointing downward and have a cutting edge along the rotation direction.
[0041] The rotating rod 12 is provided with a plurality of brushes 18 , and the brushes 18 are in contact with the second filter screen 19 ;
[0042] Specifically, it is explained here that the second filter screen 19 is a cylindrical surface, that is, the partition is arc-shaped, forming a cylindrical space.
[0043] Specifically, in the third embodiment, the centrifugal separation structure is optimized and the cleaning function of the brush 18 is added to improve the sand washing effect. The working principle is as follows:
[0044] Function of blades 14: After entering the lower box 2, the sand is deeply cleaned by the centrifugal sand washing structure. The motor 16 installed under the lower box 2 drives a pair of rotating rods 12 and the blades 14 thereon to rotate at high speed, generating a strong centrifugal force to further remove the dirt and impurities attached to the surface of the sand. Through the rotation of the rotating rod 12, the centrifugal force separates the impurities from the sand body, and further filters through the second filter screen 19. The sand body remains inside the second filter screen 19, and the impurities pass through the second filter screen 19 and are discharged along the sewage outlet 7.
[0045] Brush 18 cleaning and filter cleaning: A brush 18 is installed on the rotating rod 12, and the brush 18 contacts the second filter 19 to help remove impurities remaining on the filter and clean the filter to avoid clogging. The rotation of the brush 18 combined with the centrifugal force effectively improves the cleaning efficiency and the permeability of the filter.
[0046] Fine sand separation and centralized discharge: The cleaned fine sand is separated by centrifugal force and concentrated at the bottom of the lower box 2. The sand outlet 6 of the lower box 2 is located at the center of the bottom, which is convenient for discharging the cleaned sand.
[0047] Wastewater recovery and material recovery: Through the drainage pipe 5, the wastewater after centrifugal separation enters the wastewater recovery area of the lower box 2, and the fine sand is effectively recovered, reducing waste. The clean water is discharged through the sewage outlet 7, completing the recovery and recycling of wastewater and materials.
[0048] Optimized design: The structural design inside the lower box 2 has been optimized. The toothed disc and chain system at the lower end of the rotating rod 12 enhance the continuity and uniformity of sand washing. The brush 18 cooperates with the blade 14 to improve the cleaning rate and ensure the efficient recovery of sand particles. The plate-shaped blades are used to increase the thrust of the water, and the arc-shaped ones are used to crush possible impurities so that they can be thoroughly filtered.
[0049] Although the 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.
