Description

Technical Field

[0001] The utility model relates to the technical field of recycled concrete cleaning and grading, in particular to an environment-friendly recycled concrete cleaning and grading device. Background Art

[0002] Recycled concrete refers to the new concrete formed by crushing, cleaning and grading waste concrete blocks, mixing them in a certain proportion and gradation, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. Therefore, a commonly used environment-friendly recycled concrete cleaning and grading device is provided.

[0003] For example, a fine sand grading and cleaning recovery device for concrete with the publication number of "CN210138824U" has a simple structure and is easy to use. Through the reflux plate, the fine sand on each classification sieve is fully screened. In addition, the water content in the screened fine sand is reduced and the water resources are fully utilized, reducing the waste of water resources. However, in the above, the used water is pumped to the upper part by a circulation pump and sprayed into the subsequent concrete for use. Since there are impurities in the used water finally, the cleaning quality of the recycled concrete is reduced. And in the above, the water source after cleaning flows into the lowermost end of the main body, and silt will accumulate. Since the internal space of the main body is narrow and not conducive to cleaning, the practicability is low. Summary of the Invention

[0028] Working principle:

[0029] Environmentally friendly recycled concrete cleaning and grading work:

[0030] When it is necessary to clean and grade the recycled concrete, the recycled concrete is poured into the third filter screen 4 from the opening processed at the upper end of the second box body 3, and at the same time, the two nozzles 5 are connected to the external water tank through a hose and water is pumped into the nozzles 5 by an external water pump. In this way, the two nozzles 5 can be used to spray water onto the recycled concrete for cleaning, and at the same time, the external power supply of multiple vibrators 6 is turned on, and the multiple vibrators 6 are started to generate vibrations, thereby vibrating the multiple third filter screens 4. In this process, the recycled concrete will gradually flow downward and be screened and graded through multiple third filter screens 4 with different through-hole densities. The screened recycled concrete will flow into the material box 8 for collection according to the slopes of the multiple third filter screens 4 (such as Figure 2 ), such movement can screen and grade the recycled concrete.

[0031] Environmental filtration of recycled concrete washing water:

[0032] When the recycled concrete is cleaned, most of the cleaning waste water will flow downward from the multiple third filter screens 4 to the lower end of the second box body 3 (a very small part of the water flow may flow into the interior of the material box 8, but most of it will still be pumped out through the water pump 201 for subsequent circulation, so it does not affect the specific use). When a proper amount of waste water is stored at the lower end of the second box body 3, the water outlet 206 is connected to the external water tank and the valve in the middle of the water outlet 206 is opened, and then the external power supply of the water pump 201 is connected. The water pump 201 is started to pump the waste water in the second box body 3 into the third box body 204 through the cross pipe 202. The first filter screen 203 is installed at the left end of the cross pipe 202 to block a large amount of mud (such as Figure 6 ), after the wastewater enters the third box 204, the impurities inside it are filtered out by a plurality of second filter screens 205 with different through-hole densities (such as Figure 5 ), the filtered water will flow through the water outlet 206 to the external water receiving box for collection, so that the filtered water can be used for subsequent cleaning of the recycled concrete, achieving a recycling and environmentally friendly effect.

[0033] Silt cleaning work:

[0034] When it is necessary to clean the sludge at the lower end of the inner wall of the second box body 3, the two nozzles 5 stop spraying water, and after a large amount of wastewater at the lower end inside the second box body 3 is pumped out by the water pump 201, the box door in the middle of the second box body 3 is opened (the box door is buckled with the second box body 3 through a lock catch, and a sealing gasket is fixed at the connection to ensure relative sealing). Subsequently, the external power supply of the first motor 102 is connected, and the first motor 102 starts to drive the worm 103 to rotate through the bearing in the first box body 101. The rotation of the worm 103 drives the worm wheel 104 to rotate through the bearing in the first box body 101. The rotation of the worm wheel 104 drives the roller 105 to rotate through the bearing in the first box body 101. The rotation of the roller 105 drives the cross bar 106 to slide to the right in the chute processed on the inner wall of the first box body 101 through the chute processed on the outer wall and the two cylinders 108 (as Figure 4 ), the two cross bars 106 slide to the right in the second box body 3 to drive the slide plate 107 to slide to the right to scrape the sludge to one side in the direction of the box door (as Figure 3 ). Sealing rings are fixed at the connections between the two cross bars 106 and the second box body 3 to ensure relative sealing during the sliding process. Subsequently, the sludge can be collected into the box body 10 by using tools. In this way, the sludge can be cleaned.
