Description

Technical Field

[0001] This utility model relates to the field of waste cleaning technology, specifically to an automatic waste cleaning device for aerated concrete billets. Background Technology

[0002] In aerated concrete production lines, a large amount of waste is generated on both sides after the billet is cut. Traditional manual cleaning methods expose the following core problems in large-scale production scenarios:

[0003] 1. Manual cleaning is inefficient and restricts production capacity.

[0004] Traditionally, waste materials are manually pushed off piece by piece using tools such as shovels. This requires multiple workers to clean up the waste materials, resulting in high labor costs. Furthermore, the speed of manual cleaning is difficult to match the production line rhythm, leading to the accumulation of waste materials and frequent machine shutdowns for cleaning, which reduces actual production capacity and efficiency.

[0005] 2. High safety risks and frequent occupational injuries.

[0006] Manual operation requires close proximity, and when pushing materials, the tools may slip or the billet may tip over, resulting in crushing or collision injuries. In addition, the dust concentration of aerated concrete is high, and long-term exposure may lead to pneumoconiosis. When workers do not wear protective equipment, the risk of dust inhalation increases significantly, and occupational health hazards are prominent.

[0007] 3. Incomplete cleaning affects product quality.

[0008] Uneven force when manually pushing the material can easily lead to damage to the edges of the blank or waste residue. The waste residue needs to be processed again, which increases the cost of the grinding process. At the same time, the hardened waste residue is difficult to clean, which affects the product quality.

[0009] The above problems are particularly prominent in modern building materials enterprises with high requirements for automation and large production scale, and there is an urgent need for automation solutions to improve efficiency and safety. Utility Model Content

[0010] To address the technical problems existing in the background art, this utility model proposes an automatic cleaning device for aerated concrete billet waste.

[0011] This utility model proposes an automatic waste cleaning device for aerated concrete billets, including a support frame and a fixed base. A support plate opposite to the support frame is installed on the fixed base. A pushing component is installed at the upper end of the support frame. The movable end of the pushing component passes through the support plate and extends horizontally towards the aerated concrete billet, and is equipped with a pushing blade. The pushing component drives the pushing blade to move horizontally to push the waste material to the lower two sides of the aerated concrete billet. The waste material on the upper two sides of the aerated concrete billet automatically falls downwards under the action of gravity.

[0012] As a further optimization of this utility model, the side of the support plate away from the support frame is opposite to the aerated concrete blank, and a proximity switch is installed on the opposite surface.

[0013] As a further optimization of this utility model, the proximity switch is located on the side of the pusher blade and on the forward side of the aerated concrete billet.

[0014] As a further optimization of this utility model, the pushing component is a cylinder and is connected to an air compressor through a pneumatic valve. The pneumatic valve receives the sensing signal from the proximity switch and then actuates.

[0015] As a further optimization of this utility model, a pusher plate is installed on the side of the pusher blade, and one end of the pusher plate extends vertically upward for pushing the aerated concrete billet to the side.

[0016] As a further optimization of this utility model, a guide plate is installed at the upper end of the pusher blade. One end of the guide plate is seamlessly connected to the pusher plate through an arc plate, and the other end of the guide plate is inclined downward and extends beyond the edge of the support plate.

[0017] As a further optimization of this utility model, the upper end of the support plate is provided with a guide groove that matches the lower end of the pusher plate, and the lower end of the pusher plate is slidably assembled with the guide groove.

[0018] As a further optimization of this utility model, a vibration motor located above the pusher blade is installed on the side of the pusher plate.

[0019] The automatic waste cleaning device for aerated concrete billets proposed in this utility model has the following beneficial effects:

[0020] (i) The pusher component drives the pusher blade to move horizontally, automatically pushing down the waste material on both sides of the billet. The waste material on the top of the billet falls down automatically due to gravity. The pusher component is driven by a cylinder and automatically starts and stops with the sensing signal of the proximity switch. No manual intervention is required, which significantly improves the waste cleaning efficiency, reduces labor costs, and avoids the safety risks of close-range operation by personnel. It is especially suitable for large-scale production lines. Moreover, the automated push cleaning can also avoid the problem of billet edge damage or waste residue caused by uneven push force, which is conducive to improving the actual product quality.

[0021] (ii) A vertical pusher plate is installed on the side of the pusher blade, and a guide plate is set at the upper end and seamlessly connected to the pusher plate through an arc plate. The other end of the guide plate is inclined downward and extends beyond the edge of the support plate. The pusher plate slides along the guide groove to ensure the stability of the pusher process. The guide plate guides the waste to slide down in the preset direction to avoid waste accumulation or splashing. With the horizontal movement of the pusher blade, the waste on the side of the billet is thoroughly cleaned, and the cleaning effect is thorough and the residue is reduced.

[0022] (iii) A vibration motor is installed on the side of the pusher plate to generate high-frequency vibration during the pushing process, which breaks the adhesion between the waste and the blank. Especially for the waste with strong adhesion, it can make it fall off more smoothly. The vibration assistance function effectively solves the problem of waste jamming or residue in the traditional pushing method, improves cleaning efficiency, reduces the damage to the surface of the blank caused by waste residue, and ensures product quality.

[0023] (iv) The proximity switch is set on the side of the pusher knife and the forward side of the billet. It senses the position of the billet in real time and triggers the pneumatic valve to control the cylinder to ensure that the pusher knife starts accurately when the billet is in place, avoiding empty push or missed push. This precise control realizes the automatic linkage of waste cleaning and billet conveying, reduces manual operation error, and improves the coordination and stability of the production line.

[0024] (v) This device adopts a modular design, with a simple support frame and fixed base structure. Components such as pusher blade and pusher plate can be disassembled and maintained, reducing the difficulty of troubleshooting and parts replacement. Vibration motor and proximity switch are standardized components with low maintenance costs. It is suitable for industrial environments with long-term continuous operation, effectively reducing the equipment maintenance costs and downtime of enterprises.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] like Figure 1 As shown, an automatic waste cleaning device for aerated concrete billets includes a support frame 1 and a fixed base 2. A support plate 3 opposite to the support frame 1 is installed on the fixed base 2. A pushing component 4 is installed at the upper end of the support frame 1. The movable end of the pushing component 4 passes through the support plate 3 and extends horizontally towards the aerated concrete billet, and is equipped with a pushing blade 5. The pushing component 4 drives the pushing blade 5 to move horizontally to push the waste material on both sides of the lower part of the aerated concrete billet. The waste material on both sides of the upper part of the aerated concrete billet automatically falls downward under the action of gravity.

[0034] To address the issues of time-consuming, labor-intensive, and safety-risk-prone manual cleaning of aerated concrete billet waste, this device achieves automated material pushing by driving the pusher blade 5 through the pusher component 4. The pusher component 4 is driven by a cylinder, and when the pusher blade 5 moves horizontally, it can accurately push off the waste on both sides of the billet. The waste on the upper part falls off naturally due to gravity, without the need for manual intervention.

[0035] For example, in the production line, the pusher blade 5 reciprocates with the cylinder, continuously cleaning the waste on both sides of the blank, which helps to improve the actual cleaning efficiency, while also avoiding personnel contact with dangerous areas and improving operational safety.

[0036] Specifically, the side of the support plate 3 away from the support frame 1 is opposite to the aerated concrete blank, and a proximity switch 6 is installed on the opposite surface.

[0037] The proximity switch 6 senses the position of the aerated concrete billet in real time. When the billet is delivered to the predetermined station, the proximity switch 6 sends a signal to trigger the push component 4 to act, ensuring that the pusher 5 starts accurately after the billet is in place, avoiding empty push or missed push.

[0038] For example, in a production line where the billet conveying speed is 1 m / s, the proximity switch 6 can trigger a signal 0.5 seconds before the billet arrives, ensuring that the pusher 5 and the billet arrive in sync, thus improving the coordination of the cleaning process.

[0039] Furthermore, the proximity switch 6 is located on the side of the pusher blade 5, and the proximity switch 6 is located on the forward side of the aerated concrete billet.

[0040] The proximity switch 6 is located on the forward side of the billet, which can detect the arrival of the billet in advance and ensure that the pusher 5 completes the pushing action during the movement of the billet. When the billet moves forward along the production line, the proximity switch 6 first senses the front end of the billet and triggers the cylinder to push the pusher 5 towards the billet, thereby completing the pushing of waste materials on both sides.

[0041] Furthermore, the pushing component 4 is a cylinder and is connected to the air compressor through a pneumatic valve. The pneumatic valve receives the sensing signal from the proximity switch 6 and actuates. The pneumatic valve controls the cylinder to start and stop according to the signal from the proximity switch 6, thereby realizing the automated control of the pushing action. The air compressor provides a stable air source. The cylinder has a fast response speed and an action time of <0.3 seconds, which can accurately control the stroke and thrust of the pushing knife 5.

[0042] For example, when the air source pressure is 0.6MPa, the cylinder thrust can reach 500N, which is enough to push down aerated concrete waste with a thickness of up to 50mm, and the pushing stroke can be precisely controlled within the error range of ±10mm by adjusting the opening of the pneumatic valve.

[0043] It should be noted that in actual setup, the device is arranged in pairs, corresponding to the waste on the front and rear sides of the billet respectively, so as to achieve simultaneous cleaning of waste in both directions and improve actual work efficiency.

[0044] Based on the above structure, a new embodiment is added, as follows:

[0045] like Figure 2 and Figure 3 As shown, a pusher plate 7 is installed on the side of the pusher blade 5. One end of the pusher plate 7 extends vertically upward and is used to push the aerated concrete billet to the side.

[0046] The vertically extending pusher plate 7 increases the contact area between the pusher blade 5 and the waste material, thereby improving the cleaning efficiency of the waste material on the lower side of the billet and making it easier for the waste material on the upper side to fall downwards.

[0047] Furthermore, the pusher plate 7 can extend upwards and be aligned with the height of the billet, simultaneously pushing away waste material from the upper and lower sides of the billet, further improving cleaning efficiency.

[0048] Furthermore, a guide plate 8 is installed on the upper end of the pusher blade 5. One end of the guide plate 8 is seamlessly connected to the pusher plate 7 through an arc plate 9, and the other end of the guide plate 8 is inclined downward and extends beyond the edge of the support plate 3.

[0049] The guide plate 8 is smoothly connected to the pusher plate 7 via the arc plate 9, guiding the waste material to slide down along the guide plate 8, avoiding waste splashing or accumulating on the support plate 3. The guide plate 8 is tilted at an angle of 30° and extends 100mm beyond the edge of the support plate 3, ensuring that the waste material falls directly into the collection device below. During the pushing process, the waste material slides down the guide plate 8 at a speed of up to 2m / s, quickly leaving the cleaning area and keeping the working environment clean.

[0050] Based on the structure of Embodiment 1 above, Embodiment 2 is added, as follows:

[0051] like Figure 4 As shown, the upper end of the support plate 3 is provided with a guide groove 10 that matches the lower end of the pusher plate 7, and the lower end of the pusher plate 7 is slidably assembled with the guide groove 10.

[0052] The guide groove 10 provides horizontal movement guidance for the pusher plate 7, ensuring stable pushing and retraction of the pusher blade 5 and avoiding incomplete waste cleaning due to deviation.

[0053] Furthermore, a vibration motor 11 is installed on the side of the pusher plate 7 above the pusher blade 5. The vibration motor 11 generates high-frequency vibration, which breaks the adhesion between the waste and the blank, and is especially suitable for cleaning waste with strong stickiness or strong adhesion.

[0054] For example, for aerated concrete waste with high moisture content, vibration can improve the separation efficiency between waste and green body by 40%, avoid damage to the surface of green body due to waste residue, and ensure the appearance quality of the product. The vibration motor 11 has a power of 200W, low energy consumption and significant vibration effect, and can work continuously for more than 8 hours without stopping for cooling.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
