Description

Technical Field

[0001] This application relates to the technical field of building material production, and particularly relates to a recycled concrete production device. Background Art

[0002] A recycled concrete production device is specifically designed to process recycled waste concrete blocks, convert them into high-quality recycled aggregates, and ultimately use them to manufacture new concrete products. The device cleans, processes, and utilizes waste concrete materials through a series of steps, thereby improving the quality and performance of recycled concrete. A recycled concrete production device, a recycled concrete production device

[0003] During the production process of recycled concrete, the recycled concrete block aggregates usually contain impurities such as dust and soil. These impurities seriously affect the adhesion between the recycled aggregates and the new concrete, thereby reducing the overall strength and durability of the newly made concrete bricks. In the prior art, there is a lack of effective means to thoroughly clean the impurities on the surface of these aggregates, resulting in unstable quality of recycled concrete products. In addition, in the existing device, when making concrete bricks through vibration and stamping, the recycled aggregates will move towards the outer surface of the concrete bricks under the action of vibration, making the recycled aggregates directly exposed on the surface of the new concrete bricks. This not only affects the aesthetics of the brick surface but also significantly reduces its structural strength and durability. At the same time, the existing production process rarely pays attention to how to improve the connection strength between newly made concrete bricks, which is a major defect for application scenarios that require high-strength connections. Summary of the Invention

[0004] This application proposes a recycled concrete production device, which has the advantages of the structural strength and connection strength of newly made concrete bricks, and is used to solve the problem that the recycled aggregates are directly exposed on the surface of the new concrete bricks, resulting in low structural strength of the concrete bricks.

As described above, the structure can reduce the production cost while cleaning the dust and soil on the surface of the recycled concrete block aggregate during operation.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, by starting the second telescopic rod forward, the telescopic end of the second telescopic rod drives the piston mechanism to move upward through the pressing block and the second material limiting mechanism. At this time, the plug plate at the bottom of the piston mechanism pushes the upper pollution to move upward after being filtered by the filter mechanism, causing the water level in the inner cavity of the housing to rise above the water tank. Then, the recycled concrete block aggregate is poured onto the loading plate in the inner cavity of the inner shell. After that, the first vibrating machine is started, and the first vibrating machine drives the pushing mechanism to vibrate. The pushing mechanism drives the first material limiting mechanism to vibrate, and the first material limiting mechanism drives the recycled concrete block aggregate above it to vibrate in the aqueous solution, so that the dust, soil, etc. on its surface are separated from its surface, thereby improving the adhesion strength between the subsequent recycled concrete block aggregate and the new concrete, and further improving the strength of the new concrete brick. In addition, when the plug plate moves downward, the valve opening of the mounting plate opens, and the sewage above the mounting plate in the inner cavity of the housing flows downward through the one-way valve. When the plug plate moves upward, the valve opening of the mounting plate closes, and the plug plate pushes the sewage between the upper part of the plug plate and the mounting plate to flow above the mounting plate in the inner cavity of the housing through the first filter cloth and the second filter cloth. At this time, the first filter cloth and the second filter cloth filter the sewage, thereby improving the utilization efficiency of water resources for recycled concrete bricks;

[0027] 2. In the present invention, by starting the second telescopic rod in reverse, the telescopic end of the second telescopic rod moves downward, and the second telescopic rod pushes the pressing block downward. The pressing block pushes the second limiting rod of the second material limiting mechanism and the third limiting rod of the third material limiting mechanism to move in the direction of the second telescopic rod. At this time, the second limiting rod and the third limiting rod extend into the inner cavity of the inner shell, separating the recycled concrete block aggregate from the left and right sides and the front and back sides in the inner cavity of the inner shell. At the same time, the pressing block moves downward into the inner cavity of the inner shell, squeezing the recycled concrete block aggregate and the new concrete above the loading plate in the inner cavity of the inner shell to form a square shape. At the same time, the pressing force on the loading plate squeezes the elastic sleeve to contract and move downward, and the first limiting rod extends out of the upper surface of the loading plate, separating the recycled concrete block aggregate from the upper surface of the loading plate. At the same time, the continuously vibrating first vibrating machine causes the new concrete to flow into the gaps between the recycled concrete block aggregates; between the middle parts of the left and right sides and the front and back sides of the aggregate and the inner shell; between the middle parts of the aggregate and the top surface of the loading plate; between the middle parts of the aggregate and the bottom surface of the pressing block, so that the recycled concrete block aggregate is wrapped in the middle position of the new concrete, preventing the recycled concrete block aggregate from being exposed on the surface of the new concrete brick, improving the surface strength and structural strength of the new concrete brick, and causing a large number of holes to be produced on the surface of the new concrete brick, improving the end connection strength between the newly made concrete bricks.

[0038] Please refer to Figures 1 to 6 As shown, a recycled concrete production device includes:

[0039] An outer shell 1 and an inner shell 2, and the inner shell 2 is fixedly installed in the middle of the inner cavity of the outer shell 1;

[0040] Multiple groups of water tanks 201, and multiple groups of water tanks 201 are equidistantly opened in the middle of the left and right sides and the front and back sides of the inner shell 2;

[0041] Among them, the distance between the upper surface and the lower surface of the water tank 201 is less than the diameter of the recycled and crushed concrete blocks, so as to prevent the concrete blocks from passing through the water tank 201 from the upper surface of the carrier plate 504 in the inner shell 2 cavity and falling into the cavity between the outer shell 1 and the inner shell 2;

[0042] A plurality of socket holes 202 are equidistantly arranged in the upper parts of the left and right sides and the front and back sides of the inner shell 2.

[0043] The filter mechanism 3 is arranged at the bottom of the cavity of the outer shell 1.

[0044] The pushing mechanism 4 is arranged between the cavity of the outer shell 1 and the upper surface of the filter mechanism 3.

[0045] The first material limiting mechanism 5 is arranged between the cavity of the inner shell 2 and the middle part of the pushing mechanism 4.

[0046] The second telescopic rod 6 is fixedly installed at the top of the cavity of the outer shell 1.

[0047] The pressing block 7 is fixedly installed at the telescopic end of the second telescopic rod 6.

[0048] Two second vibrators 8 are symmetrically and fixedly installed on the upper surface of the pressing block 7.

[0049] Among them, the outer shell of the second vibrator 8 is designed with a heat dissipation structure, so as to quickly transfer the heat generated by the internal motor to the air, quickly reduce the temperature of the internal motor of the second vibrator 8, and improve the service life of the second vibrator 8;

[0050] Two groups of second material limiting mechanisms 9 are symmetrically arranged on the left and right sides of the pressing block 7.

[0051] Two groups of third material limiting mechanisms 10 are symmetrically arranged on the front and back sides of the pressing block 7.

[0052] The piston mechanism 11 is arranged between two groups of second material limiting mechanisms 9, the filter mechanism 3 and the bottom of the cavity of the outer shell 1.

[0053] Please refer to Figures 2 to 4 As shown, the filter mechanism 3 includes a mounting plate 301, the mounting plate 301 is fixedly sleeved at the bottom of the cavity of the outer shell 1, first filter cloths 302 are symmetrically and fixedly sleeved on the left and right sides of the mounting plate 301, second filter cloths 303 are symmetrically and fixedly sleeved on the front and back sides of the mounting plate 301, and a one-way valve 304 is fixedly sleeved in the middle of the mounting plate 301;

[0054] Among them, the first filter cloth 302 and the second filter cloth 303 are made of dust-free cloth, so as to filter dust, sediment, etc. in the sewage passing through their surfaces. The opening direction of the one-way valve 304 is downward, so that when the plug plate 1102 moves downward, the sewage above the mounting plate 301 in the inner cavity of the housing 1 flows through the one-way valve 304 to the lower part of the mounting plate 301. When the plug plate 1102 moves upward, the valve port of the mounting plate 301 closes, and the plug plate 1102 pushes the sewage between the upper part of the plug plate 1102 and the mounting plate 301 to flow through the first filter cloth 302 and the second filter cloth 303 to the upper part of the mounting plate 301 in the inner cavity of the housing 1. At this time, the first filter cloth 302 and the second filter cloth 303 filter the sewage, thereby improving the utilization efficiency of the water resources of the recycled concrete bricks.

[0055] Please refer to Figure 2 and Figure 3 As shown, the material pushing mechanism 4 includes a connecting plate 401. The connecting plate 401 is slidably sleeved on the bottom of the inner cavity of the inner housing 2. Two first vibrating motors 402 are symmetrically and fixedly installed on the lower surface of the connecting plate 401. Curved plates 403 are symmetrically and fixedly installed on the front and rear sides of the connecting plate 401. The curved plates 403 are slidably sleeved on the inner housing 2. A first telescopic rod 404 is fixedly installed on one side of each of the two curved plates 403 away from the connecting plate 401. The bottom end of the first telescopic rod 404 is fixedly installed on the upper surface of the mounting plate 301;

[0056] Among them, the housing of the first vibrator 402 adopts a sealed design, thus preventing the aqueous solution in the inner cavity of the housing 1 from flowing into the interior of the first vibrator 402, which may cause the motor inside the first vibrator 402 to short-circuit and burn out. At the same time, the aqueous solution in the inner cavity of the housing 1 cools the motor inside the housing of the first vibrator 402 to extend the service life of the motor. When in use, when the telescopic end of the first telescopic rod 404 moves upward, the telescopic end of the first telescopic rod 404 pushes the curved plate 403 upward. The curved plate 403 drives the connecting plate 401 to move downward, and the connecting plate 401 drives the first vibrator 402 and the first material limiting mechanism 5 to move upward. When the first vibrator 402 is started, the first vibrator 402 vibrates. The first vibrator 402 drives the connecting plate 401 to vibrate, the connecting plate 401 drives the first limiting rod 502 to vibrate, the first limiting rod 502 drives the load plate 504 to vibrate, and the load plate 504 drives the concrete material above it to vibrate. When the material above the load plate 504 is recycled concrete block aggregate, the load plate 504 drives the recycled concrete block aggregate to vibrate in the aqueous solution in the housing 1, so that the dust, soil, etc. attached to the surface of the recycled concrete block aggregate fall off from the surface of the recycled concrete block aggregate, thereby improving the adhesion strength between the subsequent recycled concrete block aggregate and the new concrete, and increasing the strength of the new concrete brick. In addition, when new concrete is added to the recycled concrete block aggregate, the vibrating first vibrator 402 at this time causes the new concrete to flow into the gaps between the recycled concrete block aggregates, increasing the density of the new concrete brick, reducing cavities, and further increasing the strength of the new concrete brick.

[0057] Please refer to Figure 2 and Figure 3 As shown, the first material limiting mechanism 5 includes a limiting sleeve 501. The limiting sleeve 501 is fixedly installed on the upper surface of the connecting plate 401. A plurality of first limiting rods 502 are fixedly installed on the upper surface of the connecting plate 401 at equal intervals. An elastic sleeve 503 is slidably sleeved in the middle of the plurality of first limiting rods 502. The top ends of the plurality of elastic sleeves 503 are fixedly installed with a load plate 504. The first limiting rods 502 are slidably sleeved with the load plate 504.

[0058] Among them, when the load plate 504 is subjected to downward extrusion, the load plate 504 moves downward by squeezing the elastic sleeve 503 to contract, causing the first limiting rod 502 to extend out of the surface of the load plate 504. The load plate 504 pushes the recycled concrete block aggregate to separate from the upper surface of the load plate 504, so that the new concrete fills the space between the recycled concrete block aggregate and the upper surface of the load plate 504, thereby preventing the recycled concrete block aggregate from being exposed at the bottom surface of the newly made concrete brick, resulting in uneven strength distribution at the bottom of the newly made concrete brick, generating cracks at the connection between the recycled concrete block aggregate and the concrete, and at the same time producing a large number of circular holes on the bottom surface of the newly made concrete brick, increasing the adhesive surface between the subsequent concrete bricks, and improving the building strength.

[0059] Please refer toFigures 2 to 5 As shown in the figure, the second material limiting mechanism 9 on the left side includes a first push plate 901, the first push plate 901 is fixedly installed in the middle of the left side surface of the pressing block 7, a first push block 902 is fixedly installed at the bottom end of the first push plate 901, a first inclined block 903 is slidably sleeved on the right side of the first push block 902, a plurality of second limiting rods 904 are fixedly installed at equal intervals on the right side surface of the first inclined block 903, and the plurality of first push blocks 902 are slidably sleeved with the sleeve holes 202;

[0060] Among them, when the telescopic end of the second telescopic rod 6 pushes the pressing block 7 to move downward, the pressing block 7 pushes the first push plate 901 to move downward, the first push plate 901 drives the first push block 902 to move downward, the first push block 902 pushes the first inclined block 903 to move in the direction of the second telescopic rod 6, and the first inclined block 903 drives the second limiting rods 904 to move along the water tank 201 with which it is slidably sleeved in the direction of the second telescopic rod 6, so that the recycled concrete block aggregate is separated from the left and right side surfaces of the inner cavity of the inner shell 2, and then new concrete is filled between the recycled concrete block aggregate and the left and right side surfaces of the inner cavity of the inner shell 2, avoiding the recycled concrete block aggregate from being exposed on the left and right side surfaces of the newly made concrete brick, and at the same time generating a large number of circular holes on the left and right side surfaces of the newly made concrete brick, improving the structural strength and connection strength of the newly made concrete brick.

[0061] Please refer to Figure 2 and Figure 6 As shown in the figure, the third material limiting mechanism 10 on the front side includes a second push plate 1001, the second push plate 1001 is fixedly installed in the middle of the front surface of the outer shell 1, a second push block 1002 is fixedly installed at the bottom of the second push plate 1001, a second inclined block 1003 is slidably sleeved on the rear side of the second push block 1002, a plurality of third limiting rods 1004 are fixedly installed at equal intervals on the rear side of the second inclined block 1003, and the plurality of third limiting rods 1004 are slidably sleeved with the sleeve holes 202;

[0062] Among them, when the telescopic end of the second telescopic rod 6 pushes the pressing block 7 to move downward, the pressing block 7 pushes the second push plate 1001 to move downward, the second push plate 1001 drives the second push block 1002 to move downward, the second push block 1002 pushes the second inclined block 1003 to move in the direction of the second telescopic rod 6, and the second inclined block 1003 drives the third limiting rods 1004 to move along the water tank 201 with which it is slidably sleeved in the direction of the second telescopic rod 6, so that the recycled concrete block aggregate is separated from the front and rear side surfaces of the inner cavity of the inner shell 2, and then new concrete is filled between the recycled concrete block aggregate and the left and right side surfaces of the inner cavity of the inner shell 2, avoiding the recycled concrete block aggregate from being exposed on the left and right side surfaces of the newly made concrete brick, and at the same time generating a large number of circular holes on the left and right side surfaces of the newly made concrete brick, improving the structural strength and connection strength of the newly made concrete brick.

[0063] Please refer to Figure 2and Figure 4 As shown in Figure 4 , the piston mechanism 11 includes a plurality of sliding rods 1101. The plurality of sliding rods 1101 are respectively fixedly installed on the front side and the rear side of the first push plates 901 on the left and right sides. The plurality of sliding rods 1101 are all slidably sleeved on the mounting plate 301. A plug plate 1102 is fixedly installed at the bottom ends of the plurality of sliding rods 1101. The plug plate 1102 is slidably sleeved on the bottom of the inner cavity of the housing 1;

[0064] Among them, a cleaning liquid is provided above the inner curved surface plug plate 1102 of the housing 1. The cleaning liquid is water. Thus, while reducing the production cost, the dust and soil on the surface of the recycled concrete block aggregate are cleaned. The contact surface between the plug plate 1102 and the inner curved surface of the housing 1 is a smooth surface. Thus, the sealing performance between the plug plate 1102 and the housing 1 is improved, and the aqueous solution above the plug plate 1102 in the inner cavity of the housing 1 is prevented from leaking downward to the lower side of the plug plate 1102, resulting in an increase in production cost.

[0065] Working principle:

[0066] When the present invention is used, first start the second telescopic rod 6 in the forward direction. The telescopic end of the second telescopic rod 6 moves upward. The second telescopic rod 6 drives the pressing block 7 to move upward. The pressing block 7 drives the second material limiting mechanism 9 to move upward. The second material limiting mechanism 9 drives the piston mechanism 11 to move upward. At this time, the plug plate 1102 at the bottom of the piston mechanism 11 pushes the pollution above to move upward after being filtered by the filter mechanism 3, so that the water level in the inner cavity of the housing 1 rises above the water tank 201. Then, pour the recycled concrete block aggregate into the upper surface of the loading plate 504 in the inner shell 2. After that, start the first vibrating machine 402. The first vibrating machine 402 vibrates. The first vibrating machine 402 drives the pushing material mechanism 4 to vibrate. The pushing material mechanism 4 drives the first material limiting mechanism 5 to vibrate. The first material limiting mechanism 5 drives the recycled concrete block aggregate above it to vibrate in the aqueous solution, so that the dust, soil, etc. on its surface are separated from its surface, thereby improving the adhesion strength between the subsequent recycled concrete block aggregate and the new concrete, and further improving the strength of the new concrete brick;

[0067] Then start and start the first telescopic rod 404 in the forward direction. The telescopic end of the first telescopic rod 404 moves upward. At this time, the pushing material mechanism 4 pushes the first material limiting mechanism 5 to move upward. The first material limiting mechanism 5 pushes the cleaned aggregate above it to move downward. When the upper surface of the loading plate 504 moves above the water tank 201, at this time, the upper surface of the loading plate 504 is above the water level line, and the aggregate is separated from the aqueous solution. Then pour the newly mixed concrete into the inner cavity of the inner shell 2;

[0068] Afterwards, reverse-start the second telescopic rod 6. The telescopic end of the second telescopic rod 6 moves downward. The second telescopic rod 6 pushes the pressing block 7 downward. The pressing block 7 pushes the second limiting rod 904 of the second material limiting mechanism 9 and the third limiting rod 1004 of the third material limiting mechanism 10 to move in the direction of the second telescopic rod 6. At this time, the second limiting rod 904 and the third limiting rod 1004 extend into the inner cavity of the inner shell 2, separating the recycled concrete block aggregate from the left and right sides and the front and back sides of the inner cavity of the inner shell 2. At the same time, the pressing block 7 moves downward into the inner cavity of the inner shell 2, squeezing the recycled concrete block aggregate and the new concrete above the carrier plate 504 in the inner cavity of the inner shell 2 to make it form a square. At the same time, it compresses the elastic sleeve 503 of the carrier plate 504 to contract downward, and the first limiting rod 502 extends out of the upper surface of the carrier plate 504, separating the recycled concrete block aggregate from the upper surface of the carrier plate 504. At the same time, the continuously vibrating first vibrating machine 402 makes the new concrete flow into the gaps between the recycled concrete block aggregates; the middle parts of the left and right sides and the front and back sides of the aggregate and the inner shell 2; the middle part of the top surface of the aggregate and the carrier plate 504; the middle part of the bottom surface of the aggregate and the pressing block 7;

[0069] Thus, while improving the strength of the new concrete brick, the recycled concrete block aggregate is wrapped in the middle position of the new concrete, preventing the recycled concrete block aggregate from being exposed on the surface of the new concrete brick, improving the surface strength of the new concrete brick, and making a large number of holes on the surface of the new concrete brick, improving the end connection strength between the newly made concrete bricks. Forward-start the second telescopic rod 6. The telescopic end of the second telescopic rod 6 moves upward, resetting the pressing block 7, the second material limiting mechanism 9, and the third material limiting mechanism 10. At the same time, continue to forward-start the first telescopic rod 404 to push the new concrete brick out of the inner cavity of the inner shell 2 upward.
