Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of filtration and separation, and particularly relates to a concrete excess material separation treatment device and method. BACKGROUND

[0002] Concrete excess material refers to the remaining concrete generated during the mixing, transportation and pouring of concrete, usually due to changes in construction requirements or concrete that cannot be used. If not properly handled, these excess materials will occupy a large amount of space, pollute the environment, and may affect the soil and water sources. At the same time, if not properly cleaned, concrete excess material can also affect the normal operation of equipment, increase construction costs and waste resources. Therefore, proper excess material recycling and reuse is an important measure to ensure a clean construction site environment and improve resource utilization.

[0003] A concrete pump pipe excess material separation and collection device and method are disclosed in Chinese Patent No. 202410807683.5, which relates to the technical field of pump pipe excess material treatment, and includes a filter pipe for filtering concrete, a material conveying pipe, a second filter screen and a third filter screen. The bottom of the material conveying pipe is connected to the top of the filter pipe through threaded cooperation, and the second filter screen and the third filter screen are both movably installed in the inner cavity of the filter pipe. A disassembly assembly for quickly disassembling the second filter screen and the third filter screen is provided in the inner cavity of the filter pipe, and an anti-clogging assembly is provided in the inner cavity of the filter pipe to prevent the second filter screen and the third filter screen from being clogged. Through the cooperation of the above-mentioned parts, the convenience of disassembling and cleaning the first filter screen, the second filter screen and the third filter screen from the inside of the filter pipe is improved, and the time and effort required for cleaning the first filter screen, the second filter screen and the third filter screen is reduced.

[0004] Since the coarse aggregate such as stone has a recycling value, it is usually recycled. The conventional method is to separate it by water washing, which can ensure the cleanliness of the coarse aggregate surface and is beneficial to the subsequent preparation of concrete. However, this method can cause great water waste and pollution. Some use a regenerative granulating agent to treat concrete excess material. Although this method can quickly screen out coarse aggregate, the coarse aggregate surface is adhered with a large amount of impurities, and whether the surface of the screened coarse aggregate is clean is a key factor affecting the quality of the subsequent prepared concrete. When treating the material, if too much material is added, the treatment will not be clean, and it is difficult to completely treat some agglomerated coarse aggregate of different sizes, which affects the quality of the prepared concrete.

[0016] Compared with the prior art, the present application has the following beneficial effects: (1) The present application can automatically separate and process clean coarse aggregate without producing wastewater through the cooperation of the scraping mechanism and the scraping strip, and can be completely scraped off without dust. Specifically, the concrete leftovers treated by adding a regenerative granulating agent are poured into the scraping mechanism, and then the control plates on both sides are controlled to move transversely. During the rolling process of the material on the screening plate, the transverse reciprocating movement of the control plates on both sides causes the adjacent scraping strips to move transversely and alternately. When the inverted V-shaped blocks of adjacent scraping strips coincide, the rolling space is large, and the coarse solid material rolls down. When the inverted V-shaped blocks of adjacent scraping strips intersect, the scraper on the inverted V-shaped block continuously scrapes the surface of the coarse solid material, so that the residues adhering to the surface of the coarse aggregate are scraped off, and the fine aggregate falls into the fine aggregate groove through the screening net. In this way, the material can be rolled and scraped alternately during the rolling process, so that the residues adhering to the surface of the coarse aggregate are automatically scraped off completely in all directions, and the fine aggregate falls into the fine aggregate groove through different screening nets to avoid mixing. At the same time, the cleaned coarse aggregate falls into the cleaning circular groove, and at this time, only a small amount of dust exists on the surface of the coarse aggregate, so when the coarse aggregate falling into the cleaning circular groove is rotated by the brush to clean the surface dust, a small amount of dust falls into the lower part through the filter ring net without dust. Comprehensive, clean coarse aggregate can be automatically separated and processed without producing wastewater.

[0017] (2) The present application can realize the flattening and sufficient treatment of the material through the cooperation of the driving mechanism and the scraping mechanism, and can avoid the problem of incomplete scraping caused by too much material, and facilitate the sufficient recovery of untreated material. Specifically, under the driving of the forward and reverse motor, the first control plate and the second control plate on both sides are controlled to move reciprocatingly, realizing the transverse and alternate movement of the adjacent scraping strips for rolling type scraping. At this time, the horizontal shift plates on both sides also move reciprocatingly, and the material accumulated too high is pushed down by the shift block for treatment, so that the scraping strip can uniformly and sufficiently treat the material. Moreover, the excess material is pushed over the blocking plate and falls into the U-shaped groove and the sliding long strip, avoiding the problem of incomplete scraping caused by too much material. At the same time, due to the transverse and alternate movement of the adjacent scraping strips, the scraping of the surface of the coarse aggregate is realized, and the material falling on the sliding long strip is also intermittently pushed into the U-shaped groove through the push plate at the end of the scraping strip, so that the untreated material is sufficiently recovered by the U-shaped groove.

[0018] (3) The application can intercept the caked coarse aggregate to avoid mixing, and quickly adjust and control the size of the screened coarse aggregate, so that clean and uniform size coarse aggregate can be obtained. Specifically, since the caked coarse aggregate cannot be scraped clean, the limiting plate can quickly intercept such caked coarse aggregate that cannot be processed. At the same time, adjusting the adjusting knobs on both sides, since the lower end of the adjusting screw is rotatably connected with the rotating hole, and the limiting plate is limited by the two adjusting screws, by rotating the adjusting screws at the same time, the limiting plate can be synchronously raised or lowered, so that the distance between the limiting plate and the screening plate can be flexibly controlled, and the size of the screened coarse aggregate can be quickly adjusted and controlled, so that clean and uniform size coarse aggregate can be obtained.

[0023] EMBODIMENT

[0024] As Figures 1-11As shown, a concrete residue separation and treatment device includes a fine aggregate trough 100 and a coarse aggregate trough 200 fixedly arranged side by side. An inclined scraping mechanism 300 is fixedly installed on the fine aggregate trough 100. The scraping mechanism 300 includes a screening plate 310, with baffle plates 320 fixedly installed on both sides of the screening plate 310. A screening slot 330 is formed through the screening plate 310, and an adjusting groove 340 is formed through each of the two baffle plates 320. Multiple scraping strips 500 are movably inserted into the two adjusting grooves 340. Each scraping strip 500 includes a sliding strip 510, with vertically fixed ends at both ends. A push plate 511; multiple sliding strips 510 are arranged side by side on the adjusting groove 340; a material passage 512 is opened through the sliding strip 510, and multiple inverted V-shaped blocks 520 are fixedly connected to the top of the material passage 512, and the bottom edges of the multiple inverted V-shaped blocks 520 are fixedly connected in sequence; and one of the two triangular sides of the inverted V-shaped block 520 is closed and the other is set as a screening screen 521; scrapers 522 are fixedly provided at both ends of the top surface of the inverted V-shaped block 520; two adjacent sliding strips 510 are respectively fixedly connected to different control plates on both sides of the screening plate 310; a brush cleaning mechanism 900 is installed in the coarse aggregate trough 200.

[0025] This invention, through the cooperation of the scraping mechanism 300 and the scraping strips 500, can automatically separate and process clean coarse aggregate without generating wastewater, while also ensuring thorough scraping without dust generation. Specifically, concrete residue treated with a regenerating granulating agent is poured onto the scraping mechanism 300, and then the control plates on both sides are controlled to move laterally back and forth. As the material rolls down the screening plate 310, the lateral back and forth movement of the control plates causes adjacent scraping strips 500 to move alternately back and forth laterally. When the inverted V-shaped blocks 520 of adjacent scraping strips 500 overlap, the rolling space is large, and the coarse solids roll off. When the inverted V-shaped blocks 520 of adjacent scraping strips 500 cross, the scrapers 522 on the inverted V-shaped blocks 520 continuously scrape the surface of the coarse solids, causing the coarse aggregate to adhere to the scraping mechanism 300. Surface residues are scraped off, while fine aggregates fall into the fine aggregate trough 100 through the screening screen 521. This allows the coarse aggregates to circulate between falling and being scraped off by the scraper 522 during the rolling process, ensuring that all residues adhering to the surface of the coarse aggregates are thoroughly and automatically removed. Fine aggregates continuously fall into the fine aggregate trough 100 through different screening screens 521 to prevent mixing. Simultaneously, the cleaned coarse aggregates fall into the cleaning trough 930. At this point, only a small amount of dust remains on the surface of the coarse aggregates. Therefore, when the coarse aggregates falling into the cleaning trough 930 are cleaned by the rotating brush 950, a small amount of dust falls below through the filter ring 940 without being stirred up. This comprehensive process achieves automatic separation and treatment of clean coarse aggregates without generating wastewater.

8. The concrete waste separation and treatment device according to claim 2, characterized in that, Two rotating holes (350) are symmetrically opened at one lower end of the screening plate (310). A limiting mechanism (800) is installed on the rotating hole (350). The limiting mechanism (800) includes a limiting plate (810). A second threaded hole (811) is opened through both ends of the limiting plate (810). An adjusting screw (840) is screwed into the second threaded hole (811). The lower end of the adjusting screw (840) is a smooth end and two second limiting discs (830) are fixedly provided at the end. The lower end of the adjusting screw (840) passes through the rotating hole (350) and the screening plate (310) is located between the two second limiting discs (830). An adjusting knob (850) is fixedly provided at the upper end of the adjusting screw (840).

9. The concrete waste separation and treatment device according to claim 1, characterized in that, A high connecting plate (101) and a low connecting plate (102) are fixedly provided on the fine aggregate trough (100). The high connecting plate (101) is fixedly connected to the high part of the screening plate (310), and the low connecting plate (102) is fixedly connected to the low part of the screening plate (310).

10. A method for processing concrete waste using the concrete waste separation and treatment device according to any one of claims 1 to 9, characterized in that, Includes the following steps: S1. Pour the concrete residue treated with recycled granulation agent into the scraping mechanism (300), and then start the forward and reverse motor (450) to make the adjacent scraping strips (500) move back and forth alternately. The coarse aggregate is cyclically scraped between falling and scraping by the scraper (522) so that the residue adhering to the surface of the coarse aggregate is scraped clean in all directions. The fine aggregate continuously falls into the fine aggregate trough (100) through different screening screens (521). S2. Driven by the forward and reverse motor (450), the horizontal baffles (650) on both sides move back and forth in a cross motion to push down the material that is piled up too high and process it. At the same time, the excess material is pushed into the U-shaped trough (630) and recycled, automatically avoiding the problem of incomplete scraping due to excessive material. S3. After passing through multiple scraping strips (500), the cleaned coarse aggregate falls into the cleaning trough (930), and the clumps of coarse aggregate are intercepted and recycled by the limiting plate (810). The coarse aggregate falling into the cleaning trough (930) is cleaned of surface dust by the rotating brush (950), and the dust falls below through the filter ring (940), and the clean coarse aggregate waits to be collected.
