Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foam concrete placing machines, and more specifically, to a foam concrete discharging device and a foam concrete placing machine. Background Art
[0002] Foam concrete, also known as foam concrete, is a new type of porous lightweight concrete material containing a large number of closed pores. When pouring foam concrete using a manual handheld pouring pipe, the impact of the sprayed foam concrete is large, which easily brings air into the pouring area, resulting in uneven pore size.
[0003] To this end, a foam concrete placing machine is disclosed in the authorization announcement No. CN210589808U, in which a buffer and pressure relief device is connected to a feed pipe for conveying foam concrete into the buffer and pressure relief device, and one end of the feed pipe away from the buffer and pressure relief device is connected to a discharge port of a foam concrete production equipment, and the buffer and pressure relief device is used to pour the foam concrete into the pouring area.
[0004] However, in the above patent solution, since the foamed concrete is discharged outward from the discharge channel on one side of the buffer decompression device, a blind area for casting exists at the bottom of the buffer decompression device. The foamed concrete discharged outward converges into the blind area, which may affect the casting effect. Therefore, it is necessary to further consider how to optimize the distribution flow, and this application is specially proposed to ensure that the pores are evenly distributed and the casting effect is good. Utility Model Content
[0005] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model proposes a foam concrete discharging device, the central channel of which avoids the blind area of pouring at the bottom of the discharging device, and the lateral channel expands the pouring coverage area of the discharging device, thereby improving the pouring efficiency.
[0006] The utility model also provides a foam concrete placing machine with the discharging device.
[0007] The technical solution adopted by the utility model is to provide a foam concrete discharging device, which includes a main body, wherein the main body has a first end and a second end opposite to each other, the first end is used for an external feed pipe, and the second end has a plurality of cross-arranged openings, the non-overlapping areas of the openings are lateral channels, and the overlapping areas are central channels, the lateral channels are separated from the central channel and are both connected to the first end.
[0008] Compared with the existing solutions, the utility model has the following advantages:
[0009] 1. Evenly distribute foam concrete: In order to avoid the problem of uneven pore size caused by air entrained into the pouring area when the foam concrete is sprayed out, the design buries the discharge end of the discharge device (i.e. the second end of the main body) below the concrete liquid level in the pouring area. The cross-arranged openings make the foam concrete evenly distributed in the pouring area, reduce the appearance of blind areas in pouring, and improve the pouring effect.
[0010] 2. Reduce blind spots and improve efficiency: The setting of the central channel avoids the occurrence of a blind spot in the bottom of the discharge device, while the setting of the lateral channels expands the area covered by the discharge device and improves the pouring efficiency. This design helps to evenly distribute the foamed concrete, speed up the pouring speed, and improve the engineering efficiency. According to one embodiment of the utility model, the lateral channels are evenly distributed circumferentially with the central channel as the center; since the sprayed foamed concrete has a large impact force, a reaction force will be generated on the discharge device during spraying. The above-mentioned setting makes the reaction force of the multiple lateral channels on the discharge device more evenly distributed, avoiding the discharge device from being out of control due to unbalanced force.
[0011] According to an embodiment of the utility model, the flow channel cross section of the central channel gradually increases from the second end to the first end, so as to reduce the pressure loss when the foam concrete flows into the central channel.
[0012] According to an embodiment of the utility model, the flow channel cross section of the lateral channel gradually increases from the second end to the first end, so as to reduce the pressure loss when the foam concrete flows into the lateral channel.
[0013] According to an embodiment of the utility model, the lateral channel is separated from the central channel by a baffle, and the baffle is provided with a through hole; the foam concrete in the central channel is discharged to the lateral channel through the through hole.
[0014] According to an embodiment of the present invention, the outlet of the lateral channel is inclined away from the central channel.
[0015] According to an embodiment of the present invention, the main body is made of metal, and the baffle is arranged inside the main body by welding.
[0016] According to an embodiment of the utility model, a plug for sealing is detachably installed at the outlet of the central channel.
[0017] According to an embodiment of the utility model, an inner step is provided at the outlet of the central channel; by inserting a plug adapted to the outlet of the central channel therein, the plug abuts against the inner step to complete the blocking of the central channel.
[0018] A foam concrete placing machine comprises any one of the foam concrete discharging devices described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example
[0032] Combination Figure 1-4As shown, in this embodiment, a foam concrete discharging device is disclosed, which includes a main body 1, the main body 1 has a first end 11 and a second end 12 opposite to each other, the first end 11 is used for externally connecting a feeding pipe, the second end 12 has a plurality of cross-arranged openings, the non-overlapping area of the openings is a lateral channel 13, and the overlapping area is a central channel 14, the lateral channels 13 and the central channel 14 are separated from each other and are both connected to the first end 11. The lateral channels 13 are evenly distributed circumferentially with the central channel 14 as the center.
[0033] Furthermore, combined with Figure 1 As shown, in this embodiment, the first end 11 of the main body 1 is externally connected to a foam concrete feed pipe, and the foam concrete is pumped into the main body 1 through the feed pipe. The first end 11 of the main body 1 is a circular joint, and the second end 12 is a cross flat tube structure. The outer shell of the main body 1 has a transition from the first end 11 to the second end 12.
[0034] Furthermore, combined with Figure 2-3 As shown, in this embodiment, the central channel 14 is square, and the four lateral channels 13 are respectively located at the four sides of the central channel 14. The flow channel cross-section of the central channel 14 gradually increases in the direction from the second end 12 to the first end 11. The flow channel cross-section of the lateral channel 13 gradually increases in the direction from the second end 12 to the first end 11. The lateral channel 13 is separated from the central channel 14 by a baffle 15, and the baffle 15 is provided with a through hole 15a. The outlet of the lateral channel 13 is inclined away from the central channel 14. The main body 1 is made of metal, and the baffle 15 is arranged inside the main body 1 by a welding process.
[0035] Furthermore, the paragraph describes that in a specific embodiment, the discharge device is connected to the feed pipe and is used to process the foamed concrete from the feed pipe. The device is designed so that the flow channel cross-sectional area of the first end 11 is larger than the cross-sectional area of the feed pipe outlet, which acts as a buffer so that the foamed concrete is decelerated and regulated after entering the discharge device. The flow channel cross-sectional area of the central channel 14 is not larger than the cross-sectional area of the feed pipe outlet. When the material distribution starts, the input amount of the feed pipe is larger than the output amount of the central channel 14, causing the foamed concrete to gradually accumulate inside the discharge device body 1 and overflow the central channel 14. Then, the foamed concrete enters the lateral channel 13 through the through hole 15a on the baffle 15, and finally flows to the casting area. This design ensures that the flow and distribution of the foamed concrete are more stable and smooth, avoiding the problem of too fast flow or uneven distribution.

The lateral channels 13 are evenly distributed circumferentially with the central channel 14 as the center. The difference of this embodiment is that a plug for sealing is detachably installed at the outlet of the central channel 14. An inner step 14a is provided at the outlet of the central channel 14, and an adapted plug is inserted therein so that the plug abuts against the inner step 14a to complete the blocking of the central channel 14. This design allows the central channel 14 to be blocked as needed, providing greater flexibility and controlling the flow direction and flow rate of the foam concrete.
