Technical Field

[0001] The invention relates to the technical field of sand control, in particular to a device for cleaning a parent material of sand making by air separation and dry method. Background Art

[0002] With the increasing scarcity of natural sand resources and the continuous expansion of construction scale in recent years, it has become an inevitable trend to use machine-made sand to replace natural sand in concrete. Among them, machine-made sand is defined as rock particles with a particle size of less than 4.75mm made by mechanical crushing and screening, but does not include particles of soft rock or weathered rock. At present, the method of making machine-made sand is to adopt the wind selection dry sand making method for environmental protection. This method of sand making generally includes: selecting and cleaning the parent material (parent rock) → multi-stage crushing → multi-stage vibration screening → crushed stone shaping and washing, etc. This series of operations realizes sand making.

Natural sand is mostly yellow in appearance and has a high mud content that is not easy to see. Therefore, all natural sand needs to be cleaned. The current cleaning method is to put all natural sand into the same water tank, and stir the natural sand to make it collide with each other, so as to separate the sludge on the surface from the sand and gravel, and then remove the sludge floating on the water.

DETAILED DESCRIPTION

[0030] like Figure 1-3 As shown, the present invention provides a wind selection dry sand making parent material cleaning device, comprising a cleaning box 1, and the cleaning box 1 is provided with a box cover 15;

[0031] A plurality of stirring mechanisms are provided in the cleaning box 1, the lower ends of the stirring mechanisms are fixed to the bottom wall of the cleaning box 1, and the upper ends of the stirring mechanisms are detachably connected to the box cover 15;

[0032] The box cover 15 is provided with a first opening, and a first opening cover 14 for closing the first opening is provided on the first opening, and the first opening cover 14 is connected to the edge of the first opening through a first flap 11, and the first opening is connected to a sorting mechanism for sorting sand and gravel according to the color of the sand and gravel;

[0033] The cleaning device further comprises a processor and a power supply. The processor is respectively connected to the stirring mechanism, the first cover flipper 11 and the sorting mechanism by signal. The power supply is respectively connected to the processor, the stirring mechanism, the first cover flipper 11 and the sorting mechanism by electrical signal.

[0034] When the cleaning device of the present invention is in operation, firstly, sufficient water is put into the cleaning box 1, and then, the power is turned on so that the processor, the stirring mechanism, the first cover flipper 11 and the sorting mechanism are all in working state. The sand and gravel to be sorted are put into the sorting mechanism, which sorts the sand and gravel according to their colors and sends them into the corresponding cleaning box 1. When the sand and gravel are sent into the corresponding cleaning box 1, the processor controls the first flap 11 of the corresponding cleaning box 1 to open, so that the first port cover 14 is opened, so that the sand and gravel fall into the cleaning box 1. After all the sand and gravel are sorted, the processor controls the first flap 11 to close, so that the first port cover 14 is closed. At this time, the processor controls the stirring mechanism to stir in the cleaning box 1. When stirring, the stirring mechanism stirs both the sand and gravel and the water. After stirring, the sand and gravel collide with each other, and the mud on their surfaces is removed, and then the water absorbs the mud. The stirring strength of the set stirring mechanism is determined according to the mud content of the sand and gravel in the cleaning box 1. After the set time, the sand and gravel in the cleaning box 1 are taken out to complete the cleaning of the parent material of the sand and gravel.

[0035] In the present invention, due to long-term weathering and environmental reasons, sand and gravel of different colors have different mud contents. The darker the color, the more mud and sand it contains. The more mud and sand it contains, the greater the strength of the stirring mechanism is, and the longer the cleaning time is.

[0036] On the basis of the above technical solution, the cleaning of the present invention is further optimized by introducing a cleaning belt with an adsorption layer. At the same time, in order to prevent entanglement between the cleaning belts and increase the collision of sand and gravel, a plurality of magnets with the same external magnetic poles are arranged on the cleaning belt.

[0037] Specifically, the present invention further defines the stirring mechanism, which comprises a motor 5 fixed to the bottom wall of the cleaning box 1, a stirring shaft 16 is connected to the output shaft of the motor 5, and the other end of the stirring shaft 6 is connected to the bottom of the box cover 15 through a bearing 10;

[0038] The processor is connected to the motor 5 by signal, and the power supply is connected to the motor 5 by electricity.

[0039] The stirring mechanism works by rotating the output shaft through the motor 5, thereby rotating the stirring shaft 6, thereby stirring the water in the cleaning box 1, so that the sand and gravel in the cleaning box 1 also move, collide with each other, and knock off the soil on the surface.

[0040] The stirring shaft 16 is in a spiral shape. The spiral stirring shaft 16 can increase the collision between the stirring shaft 16 and the sand and gravel while stirring the water, thereby increasing the collision between the sand and gravel, improving the cleaning efficiency, and making every sand and gravel be cleaned.

[0041] In order to further increase the cleaning efficiency, the sand and gravel collide with each other, and the sand and gravel collide with the device parts. In the present invention, a plurality of cleaning belts 9 are sequentially connected to the surface of the stirring shaft 16 from top to bottom, and an adsorption layer 20 is provided on the cleaning belt 9. While the sand and gravel collide with the cleaning belt 9, the stubborn stains on the surface of the sand and gravel can also be cleaned by the adsorption layer 20 on the cleaning belt.

[0042] In addition, in the present invention, a plurality of magnets 8 are evenly arranged on both sides of the cleaning belt 9, and the outward magnetic poles of each magnet 8 are the same. In the present invention, the magnets 8 can not only increase the counterweight of the cleaning belt 9, so that when the cleaning belt 9 collides with the sand and gravel, it is equivalent to whipping the sand and gravel, so that the stains on the surface of the sand and gravel are cleaned, but also the magnets 8 can prevent the adjacent cleaning belts 9 from being entangled through the repulsive force therebetween, and the magnetic environment created by the magnets 8, in practice, compared with ordinary counterweights, the sand and gravel cleaned out are also cleaner.

[0043] In the present invention, a vibrator 7 is provided on the outside of the cleaning box 1, and the vibrator 7 is fixed on the support block 3, and the support block 3 is connected to the outer surface of the cleaning box 1 through the L-shaped support body 2;

[0044] The vibrator 7 is signal-connected to the processor, and the vibrator 7 is electrically connected to the power supply.

[0045] When the processor controls the stirring mechanism for cleaning, the processor simultaneously starts the vibrator 7 at a set frequency, so that the vibrator 7 vibrates the cleaning box 1, thereby causing the water in the cleaning box 1 to vibrate. When the water vibrates, it will generate a greater cleaning force, which is beneficial for the cleaned sand and gravel to be cleaner.

[0046] The sorting mechanism of the present invention is used to classify sand and gravel with different specifications of mud content. At present, when sand and gravel are classified, due to the influence of climate, environment and time, the mud and sand of natural sand and gravel will adhere firmly to the surface of the sand and gravel. The stronger the mud and sand, the darker the color of the surface will be, presenting a dark khaki color. Therefore, the work of the sorting mechanism of the present invention is to sort the sand and gravel according to its color. The present invention uses a color sensor and a corresponding sorting channel 13. Each sorting channel 13 corresponds to a cleaning box 1. The sorted sand and gravel directly enter the corresponding cleaning box 1, and the sand and gravel are cleaned according to the stirring time and strength corresponding to the cleaning box 1.

[0047] In the present invention, the sorting mechanism includes a sorting channel 13 connected to the first opening, the top of the sorting channel 13 is connected to the main channel 12, the main channel 12 is inclined, a second opening is provided on the main channel 12, the second opening is communicated with the sorting channel 13, a second opening cover 17 for closing the second opening is provided on the second opening, the second opening cover 17 is connected to the edge of the second opening through a second flip cover 18, and a corresponding color sensor 19 is provided obliquely above each second opening, and the color sensor 19 is arranged inside the main channel 12;

[0048] The second cover flipper 18 and the corresponding color sensor 19 are respectively connected to the processing signal, and the second cover flipper 18 and the color sensor 19 are respectively electrically connected to the power supply.

[0049] The main channel 12 only allows one gravel to pass through at a time. When the gravel passes through, the color sensor 19 collects the color of the gravel. The processor determines that the color of the gravel meets the corresponding range, and the processor will open the corresponding second flap 18, so that the second port cover 17 is opened for a certain period of time, that is, after the gravel falls into the cleaning box 1, the processor will close the corresponding second flap 18, so that the second port cover 17 is closed, and repeat in sequence until all the sand and gravel are sorted.

[0050] In the present invention, the bottom of the cleaning box 1 is provided with a support foot 4. In order to support the cleaning box 1 more stably, a suction cup 6 is provided at the bottom of the support foot 4. The suction cup 6 can be used to extract air from the suction cup 6 by a vacuum pump, thereby ensuring the stability of the cleaning box 1.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
