Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the continuous cleaning and screening all-in-one machine for soil with multiple particle size sections comprises a shell, wherein a material inlet and a liquid inlet are formed in the top of the shell, a material guide plate connected with the material inlet is arranged in the shell, and the bottom of the material guide plate is obliquely arranged towards the inner wall of the shell. The material is added from the material inlet and is entered into inside the casing, and the washing reagent that washs soil enters into in the casing from the liquid inlet, and soil accomplishes the cleaning process inside the casing promptly.
In order to realize the washing and the screening of soil simultaneously, include three purge chamber down from last in the casing at least, every purge chamber independently washs soil to through the screen cloth that the one deck slope was placed between per two purge chambers, the contained angle of screen cloth and horizontal plane can set up between 0 degree to 45 degrees. Because the aperture of each layer of screen is larger than that of the adjacent screen below the screen, the soil is automatically screened from the top cleaning chamber to the bottom cleaning chamber from large to small, and the soil with at least more than three particle size sections can be obtained simultaneously.
In addition, the soil is great in the cohesion of solution, in order to make the screening more thorough, one side of every purge chamber is provided with the gas inlet tube that is used for leading in compressed air, and the air inlet tube sets up with the material entry homonymy. The air outlet of gas inlet tube is located the top of screen cloth one end in this purge chamber, and compressed air gets into the purge chamber from gas inlet tube, under compressed air's stirring effect, can destroy the reunion of soil, can make the particle size screening more thorough. The gas induction pipe of part is the return bend in the casing to the air outlet of gas induction pipe is towards the clean room wall, and is about 45 degrees with the contained angle of clean room wall, and compressed air gets into the clean room and carries out the stirring effect to soil, and compressed air makes gaseous resilience with clean room wall effect simultaneously, can increase compressed gas's dwell time, thereby increases the stirring effect time to soil, strengthens the screening and the cleaning performance of soil.
The material is washd and is stirred the back and need export from the material, and the material export sets up at the opposite side of every purge chamber, specifically does, and every purge chamber one side is provided with an air inlet pipe, and the opposite side is provided with a material export, and air inlet pipe and material export set up in the relative both sides of purge chamber wall, and the material export is connected with the other end of screen cloth.
The outside of the shell is provided with a material collector corresponding to the material outlet, so that the cleaned and screened soil can be conveniently collected in a centralized manner. Set gradually between material export and the material collector and be connected with screw elevator and water strainer, screw elevator's one end is the feed inlet, feed inlet and material exit linkage, screw elevator's the other end is the discharge gate, the discharge gate is connected with the filter screen one end that leaks, the other end and the material collector of the filter screen that leaks are connected, soil from the material export back through screw elevator automatic send to the material collector in, the washing liquid that soil closed behind the water strainer can see through the water strainer filtering.
The top purge chamber is connected with outside back flow, and the back flow is used for retrieving the washing liquid that the water strainer filtered out to the casing in, and on the one hand the centralized processing has the washing liquid, avoids the polluted environment, and on the other hand also makes washing liquid can used repeatedly, reduce cost. The pipe body of the return pipe is provided with a plurality of water leaking openings, the number of the water leaking openings is the same as that of the spiral elevator, and the discharge hole of the spiral elevator is connected with the corresponding water leaking opening.
Because the particle size of soil when in the bottom purge chamber is less, consequently the discharge gate of bottom purge chamber can set up at the lateral wall, also can set up in the bottom. When the material outlet is arranged at the bottom, the two side walls of the cleaning chamber are obliquely arranged, so that soil can move downwards to enter the material collector.
In order to avoid the generation of flying dust, the whole soil cleaning and screening process is carried out in solution. Because continuous feeding is needed and the capacity in the shell is limited, a water level overflow port is also arranged at the top of the shell, and the solution can be ensured to be always kept at the same height. The height of the water level overflow port is higher than the water leakage port of the return pipe body and lower than the horizontal plane of the water filter screen.
The inner wall of the shell is also fixedly provided with a heater and an ultrasonic generator, so that the soil repairing or decontaminating effect is enhanced.
The process of cleaning and screening soil with multiple grain diameter sections is shown in figure 2, firstly, a heater and an ultrasonic generator are turned on, cleaning reagents are added from a cleaning liquid adding port until cleaning liquid flows out from a water level overflow port, then soil to be screened and cleaned is added into a shell from a material inlet, the soil enters the cleaning liquid along the inner wall of a top cleaning chamber under the action of a material guide plate, a valve on an air inlet pipe is opened, compressed air enters the shell, the soil moves to the right side of the cleaning chamber along a screen which is obliquely arranged on a first layer under the stirring and gravity dual-acting force of the compressed air, and the soil with the largest grain diameter section is cleaned. When soil moves on the top screen, soil with the particle size section smaller than the aperture of the screen mesh enters the next cleaning chamber through the screen mesh to be cleaned and screened until the soil is screened to the bottom cleaning chamber, and the soil can be cleaned and screened simultaneously. The soil of different particle diameter sections after washing and screening is under the screw elevator effect, and the soil clamp area has the washing liquid to move to the material collector, and when passing through the filter screen, the washing liquid passes through the rate net and flows into the return pipe in, keeps the liquid level the same inside and outside the casing, and the different particle diameter section soil after the washing is collected to material collector at last.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
