Description

Technical Field

[0001] The utility model belongs to the technical field of concrete block production equipment, and in particular relates to concrete block filling equipment. Background Art

[0002] Autoclaved aerated concrete is a porous silicate material that uses quartz sand and other siliceous materials as the main raw materials, lime and cement as calcium cementitious materials, and aluminum powder as a foaming agent. The raw materials are ground and the slurry is prepared. The chemical reaction of aluminum powder in an alkaline environment produces hydrogen, which makes the slurry expand. It is formed under autoclaving and curing conditions. It is a new type of wall material with lightweight, thermal insulation and heat-insulating properties. After the autoclaved aerated concrete block slurry is prepared, the liquid slurry needs to be poured into the mold box for solidification.

[0003] However, during the filling process of autoclaved aerated concrete block slurry, the slurry will splash and bubbles are easily generated inside the slurry. After the slurry solidifies, cavities are formed in the autoclaved aerated concrete block, which will affect the compressive strength and product quality of the autoclaved aerated concrete block.

[0004] Prior art, such as the document with authorization announcement number CN220113604U, discloses a slurry filling device for autoclaved aerated concrete blocks, comprising a workbench, a fixed frame fixedly mounted on the upper part of the workbench, a slurry storage tank fixedly mounted on the upper part of the fixed frame, a shrinkage slurry outlet pipe connected to the bottom of the slurry storage tank, a pre-curing box arranged on the upper part of the workbench, a bubble removal net arranged at the bottom of the shrinkage slurry outlet pipe, and a processing assembly arranged on the upper part of the workbench, wherein the processing assembly comprises a vibration mechanism arranged on the upper part of the workbench, the vibration mechanism is connected with a disassembly and assembly mechanism, one end of the spring is fixedly connected to the connecting column, the spring is sleeved on the outer wall of the sliding rod, the connecting column is slidably connected to the mounting plate through the sliding rod, and the pressure rod is pressed against the pressure block through the motor.

[0005] The working principle of defoaming of the device is: the motor drives the pressure rod and the pressure block to press each other, and with the cooperation of the slide rod and the spring, the connecting column reciprocates left and right on the outer wall of the slide rod, so that the defoaming net can achieve a vibration effect and improve the defoaming effect.

[0006] However, the device still has the following problems: the center of the debubble net needs to avoid the slurry outlet pipe, and because the debubble net needs to reciprocate left and right, the opening in the center of the debubble net is large, and the area with the opening cannot be defoamed, affecting the quality of the final concrete block.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms such as "setting" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection: it can be a mechanical connection or an electrical connection: it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1

[0034] The utility model provides a concrete block filling device, comprising a workbench 11, a fixed frame 12 arranged on the workbench 11, a feed hopper 13 arranged on the fixed frame 12, a telescopic slurry discharge pipe 14 connected to the feed hopper 13, a pre-curing box 15 arranged on the workbench 11, a lifting structure 16 arranged at the lower end of the fixed frame 12, and a mounting plate 17 connected to the lifting structure 16 and having a slurry delivery port connected to the telescopic slurry discharge pipe 14 at the center.

[0035] It is worth noting that the above structure is mentioned in the prior art (CN220113604U), so the specific structure will not be elaborated in detail. The basic process that can be realized by the above structure is: the manual operation lifting structure 16 drives the installation plate 17 to move downward until the lower end of the telescopic slurry outlet pipe 14 is close to the bottom of the pre-curing box 15, the slurry is input into the feed hopper 13, and the slurry enters the pre-curing box 15 from the telescopic slurry outlet pipe 14. With the injection of slurry, the lifting structure 16 is controlled to drive the installation plate 17 to move upward stably to reduce the splashing of the material during the grouting process.

[0036] This embodiment mainly performs structural modification on the defoaming component based on the above structure, in order to further improve the defoaming effect, as follows:

[0037] In this embodiment, the filling equipment also includes a first sliding track component 1 and a second sliding track component 2 which are symmetrically arranged at both ends of the lower surface of the mounting plate 17 and distributed along the length direction of the mounting plate 17, and two defoaming components 3 which are respectively slidably connected to the first sliding track component 1 and the second sliding track component 2; the end of the defoaming component 3 extends along the width direction of the mounting plate 17, and the end of the defoaming component 3 has an avoidance component 4 which avoids the telescopic slurry discharge pipe 14 by rotating.

[0038] In this embodiment, the first sliding track component 1 includes a first fixing bar 101 arranged on the lower surface of the mounting plate 17 and distributed along the length direction of the mounting plate 17, a first side opening slide groove 102 arranged on the first fixing bar 101, a screw 103 rotatably connected in the first side opening slide groove 102, a motor 104 arranged on the mounting plate 17 and driving the screw 103 to rotate, and a first slider 105 slidably connected in the first side opening slide groove 102 and threadedly connected to the screw 103; the side end of the first slider 105 is used to install the defoaming component 3.

[0039] The first sliding track component 1 provided in this embodiment can achieve the following: when the motor 104 drives the screw 103 to rotate, the first slider 105 is restricted by the first side opening slide groove 102 and is driven by the screw 103 to move along the direction of the first side opening slide groove 102, so that the defoaming component 3 at the end of the first slider 105 can completely pass through the casting surface of the entire pre-curing box 15, thereby exerting a full defoaming effect.

[0040] In this embodiment, the second sliding track component 2 has the same structure as the first sliding track component 1 , and the two defoaming components 3 have the same structure.

[0041] In this embodiment, the defoaming component 3 includes a fixed block 301 arranged at the side end of the first slider 105, and a connecting rod 302 arranged between the fixed block 301 and the following mounting block 404; the defoaming net is installed between the fixed block 301 and the mounting block 404.

[0042] Considering that the defoaming net commonly used in the art has low structural strength and is easily deformed under stress, in the defoaming component 3 provided in this embodiment, the fixed block 301 and the connecting rod 302 are mainly used to support the defoaming component 3 and the avoidance component 4 to remain at the same horizontal height, ensuring that the defoaming net is always parallel to the casting surface and fully exerting the defoaming effect.

[0043] In this embodiment, the avoidance member 4 includes a connecting block 401 arranged on the end of the defoaming member 3, a side opening groove 402 arranged on the connecting block 401, a fixing rod 403 arranged in the side opening groove 402, a mounting block 404 rotatably connected to the fixing rod 403, and a torsion spring 405 connected to the fixing rod 403 at one end and to the mounting block 404 at the other end; a defoaming net extending along the width direction of the mounting plate 17 is arranged at the side end of the mounting block 404.

[0044] The avoidance component 4 provided in this embodiment can achieve the following: when the defoaming component 3 drives the avoidance component 4 as a whole to pass through the telescopic pulp outlet pipe 14, the tube wall of the telescopic pulp outlet pipe 14 reacts on the mounting block 404, prompting the mounting block 404 to overcome the resistance of the torsion spring 405 and rotate until the mounting block 404 and the defoaming net pass through the telescopic pulp outlet pipe 14 smoothly. After the external force disappears, the torsion spring 405 acts on the mounting block 404 to restore it to its original position.

[0045] It should be particularly noted that, considering the characteristic that the common defoaming net is easily deformed by force, a frame connected to the mounting block 404 is provided at least at the end of the defoaming net away from the mounting block 404 to protect the defoaming net and prevent the defoaming net from being deformed by direct force, thereby losing the defoaming effect.

[0046] In this embodiment, the height of the lower surface of the two defoaming nets is equal to or lower than the lower surface height of the fixing block 301 and the mounting block 404. The purpose of this arrangement is to prevent the fixing block 301 and the mounting block 404 from contacting the casting surface and affecting the flatness of the casting surface.

[0047] Example 2

[0048] The difference between this embodiment and embodiment 1 is that the structure of the second sliding track component 2 is different from that of the first sliding track component 1, as follows:

[0049] The second sliding track component 2 includes a second fixed strip 201 arranged on the lower surface of the mounting plate 17 and distributed along the length direction of the mounting plate 17, a second side opening slide groove 202 arranged on the second fixed strip 201, a fixed slide rod 203 arranged in the second side opening slide groove 202, and a second slider 204 slidably connected to the fixed slide rod 203; the side end of the second slider 204 is used to install the defoaming component 3.

[0050] In this embodiment, a connecting plate 303 is provided between the two defoaming components 3, and its two ends are respectively connected to the first slider 105 and the second slider 204 and is located at the upper end of the fixed block 301. The connecting plate 303 is provided with a first fixing bolt 304 for connecting to the fixed block 301, and the connecting plate 303 is provided with a second fixing bolt 305 for connecting to the mounting block 404.

[0051] In this embodiment, by adding the connecting plate 303 between the second sliding track member 2 and the defoaming member 3, what can be basically achieved is that when the first sliding track member 1 drives the defoaming member 3 connected thereto to move, the connecting plate 303 is transmitted to the defoaming member 3 connected to the second sliding track member 2, driving the defoaming member 3 to slide synchronously along the second sliding track member 2. The advantage of such a setting is that the synchronization rate of the two defoaming members 3 is ensured, the uniformity of the defoaming effect is improved, and at the same time a driving motor is saved, thereby reducing the economic cost.

[0052] In this embodiment, the upper surface height of the connecting plate 303 is lower than the upper surface height of the first slider 105 or the second slider 204. The purpose of this arrangement is to provide space for disassembling the first fixing bolt 304 and the second fixing bolt 305, thereby improving the efficiency of disassembling the defoaming net and facilitating replacement and cleaning of the defoaming net.

[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
