Technical Field

[0001] The utility model relates to an aerated concrete device, in particular to a screening device for aerated concrete, belonging to the technical field of aerated concrete equipment. Background Art

[0002] Aerated concrete blocks are a new type of building material that is lightweight, porous, heat-insulating, fire-resistant, nailable, sawable, and earthquake-resistant, and is widely used in high-rise frame structures. Before making aerated concrete blocks, the raw materials for making them need to be screened. The existing screening devices are prone to problems such as mesh blockage and a large number of raw material agglomerates during the screening process, which affect the screening speed of the raw materials. Therefore, this scheme proposes a screening device for aerated concrete. According to the Chinese utility model patent (application number: 202020760179.1), a screening device for aerated concrete is disclosed, including a screening chassis, a screening mechanism, a crushing mechanism and a receiving chamber are arranged in the screening chassis, the screening mechanism includes a screening cylinder and a driving motor, a feeding pipe is arranged at the right end of the screening cylinder, the left end of the screening cylinder is connected to the driving motor, a first discharge port is arranged at the bottom of the screening cylinder, a guide plate is arranged on the inner wall of the screening cylinder, the crushing mechanism includes a crushing chamber and a reduction motor, a rotating shaft is arranged in the crushing chamber, a crushing blade is arranged on the rotating shaft, the upper end of the rotating shaft is connected to the reduction motor, the discharge end of the receiving hopper is connected to the crushing chamber, a screen is arranged at the bottom of the crushing chamber, a second discharge port is arranged at the bottom of the crushing chamber, and the receiving chamber is arranged at the bottom of the screening chassis.

DETAILED DESCRIPTION

[0025] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0026] like Figure 1-Figure 6 As shown, the screening device for aerated concrete provided in this embodiment includes a frame 1, a transmission mechanism 2 is fixedly installed at one end of the frame 1, a screening drum 3 obliquely installed on the inner side of the frame 1 is connected to the output end of the transmission mechanism 2, a coarse material hopper 4 installed on the frame 1 is provided below the transmission mechanism 2, a feed hopper 5 is fixedly connected to the other end of the frame 1, a lower material hopper 6 located below the screening drum 3 is fixedly connected to the inner side of the frame 1, an extrusion mechanism 7 located above the screening drum 3 is rotatably installed on the inner side of the frame 1, and a hammering mechanism 8 rotatably installed on the inner side of the frame 1 is provided on one side of the extrusion mechanism 7.

[0027] By obliquely installing the screening drum 3 on the inner side of the frame 1, screening is performed as the screening drum 3 rotates. Small particles pass through the screening drum 3 and enter the lower hopper 6, while large particles slide down in the screening drum 3 under the action of gravity and flow out of the coarse material hopper 4. There is no need to install a guide plate in the screening drum 3, and the screening efficiency is higher. During long-term use, large-particle concrete will get stuck on the screening drum 3, affecting the screening. Through the arrangement of the squeezing mechanism 7 and the hammering mechanism 8, the squeezing mechanism 7 and the hammering mechanism 8 are in contact with the outer surface of the screening drum 3. As the screening drum 3 rotates, the hammering mechanism 8 will knock on the screening drum 3 to loosen the large-particle concrete, and then the squeezing mechanism 7 will squeeze the large-particle concrete to make it slide. There is no need for manual disassembly, cleaning and maintenance, and it is convenient to use.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 5 As shown, the squeezing mechanism 7 includes a first rotating rod 701 rotatably mounted on the inner side of the frame 1 , and an elastic squeezing roller 702 is fixedly connected to the outer side of the first rotating rod 701 .

[0029] By setting the elastic squeezing roller 702, large particles of concrete can be squeezed out better.

[0031] By setting the sieve bars 301, the distance between the two sieve bars 301 controls the screening of concrete. At the same time, due to the equal distribution of the sieve bars 301, when the sieve drum 3 rotates, the hammer 803 can hit the sieve drum 3 to cause large particles of concrete to fall off.

[0032] In this embodiment, if Figure 1 , Figure 2and Figure 3 As shown, two fixing rods 101 are fixedly connected to the top of the frame 1 , and a first rotating hole 102 rotatably matched with the first rotating rod 701 is opened on the fixing rod 101 , and a second rotating hole 103 located on the fixing rod 101 is opened on one side of the first rotating hole 102 .

[0034] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, a mounting plate 104 is fixedly connected to one end of the frame 1 .

[0035] By disposing the mounting plate 104 , the transmission mechanism 2 can run stably.

[0036] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, two rotating wheel frames 105 are fixedly connected to the other end of the frame 1, and a rotating wheel 106 located below the screening drum 3 is rotatably mounted on the inner side of the rotating wheel frame 105.

[0037] The rotating wheel 106 is provided to support the screening drum 3 and to rotate in coordination therewith.

[0038] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, baffles 107 located outside the screening drum 3 are fixedly connected to the front and back of the frame 1 .

[0039] The baffle 107 can prevent concrete from scattering out of the frame 1 .

[0040] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, a rotating shaft 302 is provided on the inner side of the screening drum 3 , and a plurality of reinforcing rods 303 are fixedly connected to the outer side of the rotating shaft 302 .

[0041] By providing the reinforcing rods 303 , the rigidity of the screening drum 3 is enhanced.

[0042] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a screening device for aerated concrete provided in this embodiment is as follows:

[0043] Step 1: Add concrete from the feed hopper 5, the transmission mechanism 2 drives the screening drum 3 to rotate, and under the action of gravity, small particles of concrete pass through the screening drum 3 and enter the lower hopper 6, and large particles will slide down in the screening drum 3 and flow out from the coarse hopper 4;

[0044] Step 2: During long-term use, large-particle concrete will get stuck between the screen bars 301 on the screening drum 3, affecting screening. The squeezing mechanism 7 and the hammering mechanism 8 are in contact with the outer surface of the screening drum 3. As the screening drum 3 rotates, the hammering mechanism 8 will knock on the screening drum 3 to loosen the large-particle concrete, and then the squeezing mechanism 7 will squeeze the large-particle concrete to make it slide.
