Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, and in particular to an aerated concrete pouring device and method which are easy to clean. Background Art

[0002] Aerated concrete blocks are a new type of building material that is lightweight, porous, heat-insulating, fire-proof, can be nailed, sawed, planed, and has a certain earthquake resistance. They are usually made of siliceous materials and calcareous materials as the main raw materials, mixed with gas-generating agents, stirred with water, and formed into pores by chemical reactions. They are made through processes such as casting, pre-curing cutting, and autoclaving. The current aerated concrete block casting device generally includes a concrete mixing device and a casting mold. The concrete mixing device will inject the slurry, cement, quicklime, gypsum and aluminum powder paste liquid into the tank according to a certain ratio for stirring. After the mixture is evenly mixed and fully reacted, the mixed slurry is injected and pressed into the casting mold through the casting pipe.

[0003] Most of the existing pouring devices have only one discharge port, and concrete is poured into the mold only through the single discharge port. Since the horizontal area of ​​the mold is larger than the horizontal area of ​​the discharge port, the flow distance of the concrete after entering the mold is long, resulting in uneven pouring and uneven thickness. At the same time, there will be problems such as uneven pore distribution and uneven product strength, which seriously reduces the pouring quality of the concrete. Summary of the invention

[0010] Preferably, there are two arc-shaped groove areas on the limiting groove, which are used to enable the opening and closing plate and the discharge pipe to rotate relative to each other.

[0011] Preferably, the projection lengths of the two arc-shaped grooves on the limiting groove on the horizontal plane are different, so as to change the opening and closing degrees of the plurality of opening and closing plates.

[0012] Preferably, it also includes: A protective cover, fixedly connected to the hanging plate; A roller, rotatably connected to the mobile frame; A sliding member, slidably connected to the moving frame, the moving frame and the sliding member being limitedly matched; A second rope is wound around the roller, one end of the second rope is fixedly connected to the hanging plate, and the second rope passes through the sliding member; A weight block is fixedly connected to the other end of the second rope.

[0013] Preferably, the guards are arranged in a staggered manner in a plurality, the number of the rollers, the sliding member, the second rope, the weight block and the elastic element are the same as the number of the guards, and the guards are spaced apart from the outlet of the distribution pipe.

[0014] Preferably, a method for pouring aerated concrete that is easy to clean, based on the above-mentioned aerated concrete pouring device that is easy to clean, comprises the following steps: Step 1: Lower the material distribution pipe, hanging plate and mobile frame into the mold until the net body and the bottom of the inner side of the mold are in contact with the hanging plate; Step 2: Open the valve and move the hanging plate upwards, during which several opening and closing plates move away from each other to allow concrete to flow through and enter the mold; Step 3: After the hanging plate moves upward to limit the moving frame, the moving frame limits the sliding member, and transmits the shock force to the shield through the sliding member and the weight, so that the net body oscillates disorderly; Step 4: During the upward movement of the sliding tube, the limiting column is limited by the limiting groove, and the limiting column rotates forward and reversely in succession, thereby changing the amount of concrete discharged per unit time, so that the amount of concrete discharged matches the amount of concrete accumulated in the mold.

The amount of concrete fed per unit time is changed by changing the degree to which several opening and closing plates are separated from each other, so that the concrete pouring progress matches the amount of concrete in the mold, thereby improving the pouring efficiency while ensuring the quality of concrete pouring. The irregular oscillating motion of the weight block is used to impact the shield, so that the mesh body is further vibrated, thereby focusing on the concrete in the lower part of the mold, making the concrete in this area more compact, and avoiding the increase in pressure on the lower part of the mold as the amount of concrete in the mold gradually increases, which makes it difficult to discharge the bubbles in the concrete in this area, thereby reducing the quality of pouring.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

[0019] like Figure 1-Figure 3As shown, an embodiment of the present invention is proposed, which provides an aerated concrete pouring device that is easy to clean, so as to solve the problems that the existing pouring device has only one outlet, resulting in a too long flow distance of concrete in the mold, causing uneven pouring, uneven pore distribution and molding defects. The device comprises: a frame 1, the frame 1 is equipped with a lifting device; a mixing tank 2, installed on the upper part of the frame 1; a discharge pipe 3, connected to the lower part of the mixing tank 2, and a valve is installed at the connection; a sliding pipe 4, slidably connected to the discharge pipe 3, and the discharge pipe 3 is connected to the sliding pipe 4; a distribution pipe 5, fixedly connected and connected to the sliding pipe 4, and a plurality of outlets are arranged on the side of the distribution pipe 5 away from the mixing tank 2; a flattening mechanism, arranged on the frame 1, for leveling the material in the mold 101; an opening and closing mechanism, arranged in the discharge pipe 3, for changing the discharge amount per unit time.

[0020] In the above scheme, the frame 1 is a high-strength steel, which is used to provide stable support for the device during operation. The lifting device is a prior art (not shown in the schematic diagram), which is used to control the up and down movement of the flattening mechanism. Its detailed working principle is not described in detail here. The valve at the connection between the discharge pipe 3 and the mixing tank 2 is an electric valve, which is used to change the connection relationship between the discharge pipe 3 and the mixing tank 2. The mixing tank 2 is a prior art, and its detailed working principle is not described in detail here. The multiple outlets on the distribution pipe 5 are evenly distributed in the horizontal direction of the mold 101, and its main components are all waterproof, which is convenient for the subsequent direct use of water to flush and clean the device, thereby improving work efficiency. When it is necessary to pour into the mold 101 When aerated concrete (for ease of description, concrete is used instead below), the lifting equipment moves the sliding pipe 4 and the distribution pipe 5 downward through the flattening mechanism, and the sliding pipe 4 and the discharge pipe 3 slide relative to each other. After the distribution pipe 5 moves downward to a preset position, it stops, and then the electric valve at the connection between the discharge pipe 3 and the mixing tank 2 is opened, and the concrete in the mixing tank 2 moves downward along the discharge pipe 3, and then the concrete passes through the sliding pipe 4 and the distribution pipe 5 and is evenly transferred to the mold 101, so that the concrete is injected from different positions of the mold 101 at the same time, reducing the flow distance of the concrete in the mold 101, thereby improving the uniformity of concrete pouring and the uniformity of pore distribution, thereby improving the pouring quality of concrete.

[0021] During the pouring process, the lifting device moves the sliding pipe 4 and the material distribution pipe 5 upward through the flattening mechanism, and at the same time utilizes the flattening mechanism to evenly distribute the bubbles in the concrete and make the concrete completely fill the mold 101, thereby improving the integrity of the concrete pouring.

[0022] like Figure 1-Figure 3As shown, the flattening mechanism includes: a first rope 601, which is in multiple numbers, one end of the first rope 601 is fixedly connected to the lifting device; a hanging plate 602, fixedly connected to the other end of the first rope 601, the hanging plate 602 is fixedly connected to the distribution pipe 5, and the hanging plate 602 is communicated with the outlet of the distribution pipe 5; a moving frame 603 is limitedly slidably connected to the hanging plate 602, the first rope 601 passes through the moving frame 603, and the two are in contact and cooperation; a mesh body 604, fixedly connected to the moving frame 603, and the mesh body 604 is located below the hanging plate 602; the mesh holes on the mesh body 604 are of different sizes, which are used to eliminate bubbles in the material in the mold 101, and the mesh area of ​​the mesh body 604 close to the outlet of the distribution pipe 5 is larger than the mesh area of ​​the remaining areas, which is used to guide the bubbles in the material in the mold 101; a vibration motor 605, installed on the moving frame 603.

[0023] In the above scheme, there are four first ropes 601, which are evenly distributed around the sliding tube 4, and are used to make the force applied to the hanging plate 602 uniform. The first rope 601 limits the moving frame 603 in the horizontal direction. Initially, the moving frame 603 is supported by the hanging plate 602. In the process of the material distribution tube 5 moving downward, the hanging plate 602 and the parts thereon move downward together under the action of their own gravity, and gradually enter the mold 101. After the net body 604 moves downward to contact the bottom of the inner side of the mold 101, it stops moving. The hanging plate 602 continues to move downward, and the hanging plate 602 and the moving frame 603 slide relative to each other until the hanging plate 602 contacts the net body 604, at which time it reaches the initial position for pouring. Then the hanging plate 602 moves upward again and starts to pour concrete into the mold 101. When the hanging plate 602 moves upward to contact the moving frame 603 After being mutually limited, the hanging plate 602 drives the moving frame 603 and the parts thereon to move upward together, and the vibration motor 605 starts to work and transmits the vibration force generated by the work to the mesh body 604. The mesh body 604 applies the vibration force to the adjacent concrete area, so that the bubbles in the concrete produce oscillating motion, thereby promoting the bubbles to float to the concrete surface and escape, thereby improving the density of the poured concrete. At the same time, since the mesh holes of different areas on the mesh body 604 have different effects on the bubbles, that is, the bubbles in the concrete in different areas are guided to different degrees (forming a channel "net" to guide the floating of the bubbles), so that the bubbles in the concrete move to the adjacent outlets on the distribution pipe 5, avoiding the traditional pouring device having only one material outlet for the bubbles to escape, and some bubbles cannot escape, resulting in holes in the concrete and reducing the pouring quality.

[0024] like Figure 4 and Figure 5As shown, the opening and closing mechanism includes: a rotating member 701, which is rotatably connected to the discharge pipe 3; a limiting column 702, which is fixedly connected to the rotating member 701, and the sliding tube 4 is provided with a limiting groove 703, and the limiting groove 703 is limited and matched with the limiting column 702, so as to make two adjacent opening and closing plates 704 contact and cooperate; there are several opening and closing plates 704 arranged circumferentially, which are all rotatably connected to the discharge pipe 3, and two adjacent opening and closing plates 704 are in contact and cooperate, and there are two arc groove areas on the limiting groove 703, which are used to make the opening and closing plates 704 and the discharge pipe 3 rotate relative to each other, and the projection lengths of the two arc grooves on the limiting groove 703 on the horizontal plane are different, which are used to change the opening and closing degree of several opening and closing plates 704; there are several connecting rods 705 arranged circumferentially, which are hinged between the rotating member 701 and the adjacent opening and closing plates 704.

[0025] In the above scheme, the two arc grooves on the limiting groove 703 have different lengths in the vertical direction (the length of the upper arc groove in the vertical direction is smaller than the length of the lower arc groove in the vertical direction), which is used to adapt to the changes in the concrete surface in the mold 101 during the pouring process. The length of the limiting groove 703 in the vertical direction is greater than the height of the mold 101. The rotation center of the opening and closing plate 704 and the discharge pipe 3 is located at its eccentric position. During the upward movement of the sliding pipe 4, the limiting column 702 begins to slide along the arc groove on the upper side of the limiting groove 703 (the limiting column 702 slides downward relative to the upper arc groove), and the limiting column 702 is limited by the upper arc groove and begins to rotate clockwise (such as Figure 4 Taking the top view as an example), the limiting column 702 drives the rotating member 701 to rotate clockwise, and the rotating member 701 and the discharge pipe 3 rotate relative to each other. The rotating member 701 drives the opening and closing plates 704 to rotate together through the connecting rod 705, so that the opening and closing plates 704 move away from each other. Then, the concrete in the discharge pipe 3 is injected into the mold 101 through the rotating member 701. As the sliding tube 4 continues to move upward, the degree to which the opening and closing plates 704 move away from each other gradually increases, that is, the "opening" gradually increases, and the amount of concrete discharged per unit time gradually increases, thereby improving the pouring efficiency.

[0026] After the limiting column 702 moves "downward" to enter the arc groove on the lower side, the limiting column 702 begins to rotate counterclockwise under the action of the arc groove on the lower side, and several opening and closing plates 704 move closer to each other, that is, the "opening" gradually decreases, and the amount of concrete fed per unit time gradually decreases, thereby accurately controlling the concrete pouring height and reducing surface defects, thereby improving the pouring efficiency while ensuring the quality of concrete pouring.

[0027] like Figure 1 , Figure 6 and Figure 7As shown, it also includes: a shield 801, fixedly connected to the hanging plate 602; a roller 802, rotatably connected to the moving frame 603; a sliding member 803, slidably connected to the moving frame 603, and the moving frame 603 and the sliding member 803 are limited and matched; a second rope 804, wound around the roller 802, one end of the second rope 804 is fixedly connected to the hanging plate 602, and the second rope 804 passes through the sliding member 803; a weight 805, fixedly connected to the other end of the second rope 804, the weight 805 is located in the shield 801, and the shield 801 is in contact with the weight 805, and an elastic element 806 is fixedly connected between the weight 805 and the sliding member 803, and the shield 801 is arranged in multiple staggered arrangements, and the number of rollers 802, the sliding member 803, the second rope 804, the weight 805 and the elastic element 806 are the same as the number of shields 801, and the shield 801 is arranged at intervals from the outlet of the distribution pipe 5.

[0028] In the above scheme, in the initial state, the movable frame 603 limits the sliding member 803, the weight 805 has no contact with the shield 801, and the elastic element 806 is a spring, which is used to provide a shock force for the weight 805 and a supporting force for the sliding member 803, and the elastic element 806 is initially in a compressed state. During the downward movement of the hanging plate 602 relative to the movable frame 603, the hanging plate 602 drives the weight 805 to move through the second rope 804 (the weight 805 moves upward relative to the shield 801), and the elastic element 806 is further compressed until the elastic force generated by the compression of the elastic element 806 is equal to the gravity of the sliding member 803, and then the weight 805 drives the sliding member 803 to move upward together through the elastic element 806, and the movable frame 603 gradually loses the limitation on the sliding member 803.

[0029] During the upward movement of the hanging plate 602 relative to the moving frame 603 (during the pouring process, and the vibration motor 605 is in working state), the hanging plate 602 gradually loses the pull on the second rope 804, and the second rope 804 begins to reset under the action of the weight block 805. During the process, the sliding member 803 and the elastic element 806 are reset together (moved downward) until the moving frame 603 limits the sliding member 803 again. At that time, it indicates that the net body 604 will move upward with the moving frame 603 at the next moment (the hanging plate 602 limits the moving frame 603 and drives it to move upward together). Due to the vibration motor 605, the vibration force will be transmitted through the sliding member 80 3 and elastic element 806 are transmitted to weight block 805, and weight block 805 performs irregular oscillating motion. During the process, weight block 805 hits shield 801, thereby further oscillating net body 604 through hanging plate 602 and moving frame 603 (changing its vibration state when net body 604 leaves the bottom of mold 101, enhancing the vibration degree of net body 604), so as to focus on the concrete in the lower part of mold 101, make the concrete in this area more dense, avoid the pressure on the lower part of mold 101 increases with the gradual increase of concrete amount in mold 101, make bubbles in concrete in this area difficult to discharge, thereby reducing the casting quality.

[0030] like Figure 1-Figure 7 As shown in FIG. 1 , an embodiment of the present invention proposes a method for pouring aerated concrete that is easy to clean. Based on the above-mentioned aerated concrete pouring device that is easy to clean, the method comprises the following steps: Step 1: Lower the material distribution pipe 5, the hanging plate 602 and the movable frame 603 into the mold 101 until the net body 604 and the bottom of the inner side of the mold 101 are in contact with the hanging plate 602; Step 2: Open the valve and move the hanging plate 602 upwards, during which the opening and closing plates 704 move away from each other to allow the concrete to flow through and enter the mold 101; Step 3: After the hanging plate 602 moves upward to limit the moving frame 603, the moving frame 603 limits the sliding member 803, and transmits the shock force to the shield 801 through the sliding member 803 and the weight 805, so that the net body 604 oscillates disorderly; Step 4: During the upward movement of the sliding tube 4, the limiting column 702 is limited by the limiting groove 703, and the limiting column 702 rotates forward and reversely in succession, thereby changing the amount of concrete discharged per unit time, so that the amount of concrete discharged matches the amount of concrete accumulated in the mold 101.
