Description

Technical Field

[0001] The present invention relates to the technical field of concrete manufacturing, and more specifically to a high-performance concrete production system. Background Art

[0002] High-performance concrete is a new type of high-tech concrete. It uses conventional materials and production processes and has all the mechanical properties required for concrete structures. It is a concrete with high durability, high workability and high volume stability. Compared with ordinary concrete, high-performance concrete has higher advantages and wider applicability, and is therefore widely used in bridges, high-rise buildings, and seaport buildings.

[0003] Concrete coarse aggregate raw materials are generally mixed with large pieces of soil and gravel, which will seriously reduce the quality of concrete, so they need to be filtered out from the concrete raw materials. Therefore, a concrete filtering and vibration device is needed. After filtering by the concrete vibration filtering device, the concrete raw materials will be more delicate and more convenient to use. The filter screen set in the existing concrete filtering and vibration device is generally set below the hopper. When discharging materials over a large area, due to the presence of gravel and large pieces of soil in the concrete raw materials, the higher throwing will easily increase the vertical force of large pieces of soil and gravel, which will cause a greater impact force on the filter screen, easily causing the mesh of the filter screen to sag and break, and increase the maintenance cost of the device.

[0004] Secondly, fine aggregate sand is mixed with crushed stone, soil, etc. and cannot be used directly for concrete mixing. The existing sand and gravel separation device is not perfect in function and there is no device for the next step of processing of the separated sand and gravel, resulting in low work efficiency.

[0005] Third, when mixing concrete, the different water content of aggregates will affect the amount of water and aggregate used in concrete. When calculating the mix ratio of various materials in concrete, if the saturated surface dry aggregate is used as the basis, it will not affect the amount of water and aggregate used in concrete, because the saturated surface dry aggregate neither absorbs water from the concrete nor releases water into the concrete mixture, so the control of the amount of water and aggregate used in concrete is more accurate. When the existing concrete aggregate conveying pre-wetting device conveys concrete aggregate on the conveyor belt, concrete aggregate is easy to leak from both sides, which not only makes the machine inconvenient to clean, but also too much concrete aggregate leaking into the machine will affect its normal use.

[0006] In the production process of high-performance concrete, a mixing device is required to mix the materials used for high-performance concrete evenly for use in construction projects. However, the existing high-performance concrete production devices often have large and high mixing barrels, and the feeding process is very inconvenient. Workers are required to transport the materials to a high place and then pour them into the production device, which is time-consuming and labor-intensive, and reduces the speed of concrete production. In addition, the existing high-performance concrete production devices often cannot mix the high-performance concrete evenly. The high-performance concrete produced usually has large particles, uneven density, and poor quality of the finished product, which affects subsequent use and reduces production efficiency.

[0007] Therefore, the existing concrete production system cannot meet the needs in actual use, so the market is in urgent need of improved technology to solve the above-mentioned problems. Summary of the invention

[0035] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0036] 1. The pre-wetting device of the present invention is provided with a water spraying mechanism, a water inlet pipe, a water delivery pipe and a water spraying head. When working, water flows into the water spraying mechanism from the water inlet pipe, and the water delivery pipe transmits the water flow to the water spraying head. Several water spraying heads are evenly distributed above the conveyor belt, and water flows from the water spraying heads to the concrete aggregates on the conveyor belt to pre-wet them. Several equidistantly arranged water spraying heads make the pre-wetting of the concrete aggregates more uniform. This solves the problem that the existing concrete aggregate conveying pre-wetting device pre-wets the concrete aggregates unevenly, resulting in the concrete aggregates that have been pre-wetted not being pre-wetted enough to meet the standard when the next step is carried out.

[0037] 2. The coarse aggregate filtering vibration device of the present invention solves the problem of filter screen damage in the existing concrete filtering vibration device by setting a filtering mechanism. The filtering mechanism is provided with an upper load-bearing net, a middle coarse filter screen and a lower fine filter screen. The upper load-bearing net is closest to the hopper port and is used to withstand the direct impact force of sand and gravel to prevent damage to the lower coarse filter screen and fine filter screen. The coarse filter screen and fine filter screen are used to filter sand and gravel comprehensively to ensure the construction quality of concrete. After the raw materials are received by the upper load-bearing net, the direct force generated on the raw materials is offset, thereby avoiding damage to the filter screen by sand and gravel.

[0038] 3. The sand and gravel separation device of the present invention solves the problem that the sand and stones separated by the existing sand and gravel separation device are easy to leak out of the device when taking, which brings certain inconvenience to the work by setting a separation bin, a talc trough, a fixed bracket and a positioning plate. The scrap car of the present invention contacts the positioning plate at one end, so that the separated stones can fall accurately into the scrap car. The talc trough is an inclined landslide, and baffles are fixedly connected on both sides to prevent stones from rolling out from both sides.

[0039] 4. The mixing production device of the present invention solves the problem that the existing high-performance concrete production device often has a large and high mixing barrel, and the feeding process is very inconvenient, requiring the staff to transport the materials to a high place and then pour them into the production device, or the angle is too large when using a conveyor belt to feed the materials, which consumes too much energy, is time-consuming and labor-intensive, and reduces the concrete production speed. The rotary cylinder drives the push rod to move forward and backward, and the slide plate can rotate at the front end of the push rod. The slide plate can slide in the slide groove to make the mixing barrel rotate with the rotating column as the axis, thereby reducing the height of the feed port, facilitating and quickly feeding the materials, saving time and labor costs, and increasing the production speed.

[0040] The device solves the problem that the existing high-performance concrete production devices often cannot mix the high-performance concrete evenly, the high-performance concrete produced usually has large particles, uneven density, poor quality of the finished product, affecting subsequent use and reducing production efficiency by arranging a mixing barrel and a rotating motor. The device drives the rotating motor to rotate the mixing blades, so that the raw materials of the high-performance concrete can be quickly mixed. After mixing evenly, the cylinder belt pass fixing plate and the rotating motor are pushed upward, and the rotating motor drives the rotating rod and the discharge barrel to move upward, so that the screen moves to the inside of the mixing barrel, and the high-performance concrete is screened and flows out of the device through the discharge barrel, thereby ensuring the quality of the high-performance concrete produced and improving production efficiency.

[0041] 5. The present invention provides a conveyor belt and a leak-proof strip both made of rubber material, which can be slightly deformed and restored, and has a waterproof function, thereby preventing materials in the conveyor belt from leaking from both sides of the conveyor belt, making cleaning inconvenient.

[0098] Working process of the present invention:

[0099] (1) Pour the coarse aggregate raw materials into the lower hopper of the coarse aggregate filtering vibration device, start the equipment, and the vibrator accelerates the descending speed of the raw materials by generating vibration. The raw materials fall into the upper load-bearing net in the inner box body. At this time, the propeller pushes the rocker, and the rocker drives the inner box body. The inner box body moves back and forth through the slide to achieve screening. The upper load-bearing net blocks the falling raw materials, slows down their falling speed, and performs preliminary filtration on the raw materials. The raw materials passing through the upper load-bearing net are filtered by the middle coarse filter screen and the lower fine filter screen, and then fall from the discharge port onto the second conveyor belt, and are conveyed by the second conveyor belt to the lower bin of the pre-wetting device.

[0100] (2) The unscreened coarse sand is fed into the separation bin from the discharge port of the sand and gravel separation device, where the sand leaks out from the small holes on the separation net, and the stones remain in the separation bin above the separation net. The sand leaking out of the separation net falls from the sand discharge port onto the third conveyor belt, and is then conveyed to the discharge bin of the pre-wetting device by the third conveyor belt. When it is necessary to take out the stones in the separation bin, the sliding door is opened, and the stones leave the separation bin through the sliding door. The stones taken out from the sliding door slide down the chute into the waste truck. The chute is an inclined landslide with baffles fixedly connected on both sides to prevent the stones from rolling out from both sides.

[0101] (3) The screened coarse aggregate and fine aggregate respectively pass through the second conveyor belt and the third conveyor belt to the lower bin of the pre-wetting device. The mixed aggregate flows down from the lower opening of the lower bin to the first conveyor belt. The other end of the water inlet pipe is connected to an external water source. When working, water flows into the water spraying mechanism from the water inlet pipe. The water pipe transmits the water flow to the water spraying head. Several water spraying heads are evenly distributed above the first conveyor belt. Water flows from the water spraying heads to the mixed aggregate on the conveyor belt to pre-wet it. Several equidistantly arranged water spraying heads make the pre-wetting of the mixed aggregate more uniform.

[0102] (4) The pre-wetted mixed aggregate is transported from the second conveyor belt to the fourth conveyor belt, and then reaches the top of the inlet of the mixing production device, and then falls into the mixing barrel. To facilitate the pouring of the mixed aggregate, a trumpet-shaped expansion port can be installed at the inlet for enclosure during pouring. Since the mixing barrel can adjust its angle, the fourth conveyor belt can reduce its angle with the horizontal.

[0103] The process of adjusting the angle of the mixing barrel is as follows: by pushing the cylinder downward to pull the fixed plate and rotating the motor, the top of the discharge barrel fits the plug-in interface to prevent the raw materials from flowing out through the discharge barrel. The rotating cylinder pushes the slide plate and the push rod forward, so that the mixing barrel can rotate in the fixed frame with the rotating column as the axis, lowering the height of the inlet.

[0104] After adding other raw materials of high-performance concrete into the mixing barrel, close the feed port, and pull the push rod and the slide backward by rotating the cylinder to rotate the mixing barrel back to the vertical state. The center of gravity of the device is lowered by the buffer column to avoid tipping. The vibration between the ground and the device is reduced by the buffer pad to avoid damage to the device after long-term use and extend the service life of the device. Start the rotating motor to make the stirring blade mix the raw materials evenly, keep the stirring blade rotating, and push the fixed plate and the rotating motor upward by pushing the cylinder to move the discharge barrel upward and move the screen to the inside of the mixing barrel. The screen will screen and refine the high-performance concrete and flow out through the discharge barrel. The rotating stirring blade can speed up the discharge speed, so that the device can produce high-quality high-performance concrete and improve production efficiency.

[0105] The conveyor belt and leak-proof strip mentioned above are made of rubber, which can be slightly deformed and restored, and have waterproof function. The leak-proof strip and conveyor belt can prevent materials from leaking from both sides of the conveyor belt, which is inconvenient to clean.
