Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a concrete spray head and a spraying component. Background Art

[0002] With the development of the construction industry, more and more concrete construction scenes choose to use concrete spraying for construction. The existing concrete spray guns have the problem of insufficient mixing of concrete and additives.

[0003] In the related art, in order to improve the mixing degree of concrete and additives by a concrete spray gun, a design of setting a motor stirring component in the spray gun has emerged, such as the patent application with publication number "CN214644722U". Although the mixing degree can be improved by stirring and mixing the concrete and additives in the spray gun with a motor stirring component, the production cost of the spray gun is high and the spray gun needs to be frequently repaired and maintained. Summary of the invention

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the first aspect of the utility model provides a concrete spray head;

[0006] A second aspect of the utility model provides a spraying assembly.

[0007] In view of this, according to the first aspect of the utility model, a concrete sprinkler is proposed, comprising: a main body, a concrete input flow channel, an additive input flow channel, a mixing flow channel and an output flow channel are arranged in the middle of the main body, wherein one end of the mixing flow channel is connected to the concrete input flow channel, the other end of the mixing flow channel is connected to the inlet of the output flow channel, and the additive input flow channel is connected to the side wall of the mixing flow channel; a spoiler is arranged in the mixing flow channel, and the spoiler is used to disturb the fluid in the mixing flow channel.

[0008] In this technical solution, a plurality of interconnected flow channels are provided in the main body, including a concrete input flow channel, which is located at the first end of the main body, an output flow channel is located at the other end of the main body, a mixing flow channel is located between the concrete input flow channel and the output flow channel, and an additive input flow channel is connected to the mixing flow channel through the side wall of the mixing flow channel.

[0009] The concrete input channel is connected to an external concrete pipeline. The concrete pipeline inputs concrete into the mixing channel through the concrete input channel. The additive input pipe is connected to the external additive pipeline. The additive flows through the additive input pipe through the additive input channel and enters the mixing channel. The additive and concrete are mixed in the mixing channel and then transferred to the output channel, and then sprayed out of the concrete nozzle through the output channel.

[0010] In this technical solution, a spoiler is provided in the mixing flow channel. When the additive and concrete flow through the spoiler of the mixing flow channel, they can be fully mixed in the mixing flow channel driven by the spoiler, thereby improving the mixing degree of the concrete and additive in the mixing flow channel and avoiding the problem of poor concrete spraying effect caused by insufficient mixing.

[0011] In the technical solution of the present application, by arranging a concrete input flow channel, an additive input flow channel, a mixing flow channel and an output flow channel in the body of the concrete sprinkler, the concrete in the concrete input flow channel and the additive in the additive input flow channel can be mixed in the mixing flow channel, and by arranging a spoiler in the mixing flow channel, when the concrete, the additive and the mixture flow through the spoiler, they can move under the spoiler effect of the spoiler, thereby improving the uniform mixing process of the additive and the concrete, and there is no need to set up a stirring component that requires an additional power source, thereby improving the convenience of the staff in using the concrete sprinkler, and eliminating the need for frequent daily maintenance and care.

[0012] In some technical solutions of the present application, the spoiler includes: a column, which is arranged in the mixing channel, and the axis of the column coincides with the axis in the mixing channel; and a spoiler rib, which is arranged on the outer side wall of the column.

[0013] In this technical solution, the spoiler includes a column and a spoiler rib. The column is arranged in the mixing flow channel and extends along the axial direction of the mixing flow channel. The spoiler rib is arranged on the outer wall of the column and is spiral. The spiral spoiler rib arranged on the column and the inner wall of the mixing flow channel form a spoiler space. When the mixed concrete and additives flow through the spoiler space, a vortex can be formed in the spoiler space, thereby improving the mixing uniformity between the concrete and the additives.

[0014] In this technical solution, the extension direction of the column matches the extension direction of the axis A of the mixing channel.

[0015] In the technical solution of the present application, the spoiler includes a column whose extension direction matches the axial extension direction of the mixing channel, and spoiler ribs arranged on the column, forming a spoiler space between the spoiler and the inner wall of the mixing channel, so that the mixture flowing through can form a vortex, further improving the mixing uniformity of the concrete and the additive.

[0016] In some technical solutions of the present application, the spoiler ribs are spirally wound around the outer wall of the column.

[0017] In this technical solution, the spoiler ribs are spirally coiled on the outer wall of the column. The spiral shape of the spoiler ribs makes the spoiler space formed between the column and the mixing channel also spiral, that is, the mixture of concrete and additives entering the mixing channel can flow in a spiral shape, thereby improving the mixing uniformity of the concrete and additives.

[0018] In the above technical solution, the size of the spoiler rib is the size of the spoiler rib protruding from the outer wall of the column. By limiting the size of the spoiler rib, the mixing degree of concrete and additives in the mixing channel can be further improved.

[0019] In some technical solutions of the present application, the spoiler includes: an isolator, which is arranged in the mixing flow channel and located at one end of the mixing flow channel close to the concrete input flow channel, and at least two channels are opened on the isolator, wherein the concrete input flow channel and the mixing flow channel are connected through at least two channels.

[0020] In this technical solution, the spoiler includes an isolator provided with a channel, and the two sides of the isolator are respectively a concrete input flow channel and a mixing flow channel, and the channel provided on the isolator connects the concrete input flow channel and the mixing flow channel, that is, the concrete in the concrete input flow channel needs to flow through the channel on the isolator to enter the mixing flow channel. Since the number of channels provided on the isolator is at least two, the concrete enters the mixing flow channel through multiple channels, that is, the direction in which the concrete enters the mixing flow channel is relatively dispersed, which is convenient for mixing with the additives entering the mixing flow channel.

[0021] In the technical solution of the present application, the spoiler is set as an isolating member with a channel, so that when the concrete flows through the isolating member, it needs to enter the mixing flow channel through the channel, so that the concrete enters the mixing flow channel in a relatively dispersed state, which is convenient for mixing with the additives in the mixing flow channel, thereby improving the mixing adequacy of the concrete and the additives in the mixing flow channel.

[0022] In some technical solutions of the present application, the isolating element is a columnar structure, at least two channels extend from one plane of the isolating element to another plane, and the extension direction of at least two channels is not parallel to the axis of the isolating element.

[0023] In the technical solution of the present application, by setting the axes of at least two channels and the axis of the isolation element to be non-parallel to each other, the concrete flowing through the at least two channels can enter the mixing channel in different directions, further improving the mixing effect of the concrete and the additive in the mixing channel.

[0024] In some technical solutions of the present application, the additive input channel includes: a first sub-channel; a second sub-channel, the first end of the second sub-channel is connected to the first sub-channel, the second end of the second sub-channel is connected to the mixing channel through the side wall of the mixing channel, and the flow area of ​​the first sub-channel is greater than the flow area of ​​the second sub-channel.

[0025] In this technical solution, the additive input channel has a first sub-channel and a second sub-channel, the second sub-channel is located between the first sub-channel and the mixing channel, and the additive in the first sub-channel flows into the mixing channel through the second sub-channel. By setting the flow area of ​​the first sub-channel to be larger than the flow area of ​​the second sub-channel, the second sub-channel can pressurize the additive flowing through, so that the additive entering the mixing channel has a higher flow potential energy, thereby improving the mixing effect of the additive and concrete in the mixing channel.

[0026] In the technical solution of the present application, the additive input channel is designed as a two-section channel including a first sub-channel and a second sub-channel, and the communication area of ​​the second sub-channel directly connected to the mixing channel is larger than the communication area of ​​the first sub-channel. When the additive flows through the first sub-channel and the second sub-channel in sequence under a certain driving force, the additive can be accelerated in the second sub-channel, so that the additive enters the mixing channel at a higher flow rate, thereby further improving the mixing effect of the additive and concrete.

[0027] In some technical solutions of the present application, the number of the second sub-channels is at least two, and the second ends of the second sub-channels are distributed around the side wall of the mixing channel.

[0028] In this technical solution, the number of second sub-flow channels is at least two, and the second ends of at least two second sub-flow channels are distributed around the side wall of the mixing flow channel. The second end of the second sub-flow channel is an end connected to the mixing flow channel. By surrounding and connecting the second ends of at least two second sub-flow channels to the side wall of the mixing flow channel, the additive in the second sub-flow channel can enter the mixing flow channel in different directions and positions, further improving the mixing effect of the additive entering the mixing flow channel and the concrete.

[0029] In this technical solution, the number of the first sub-flow channels may be one or at least two. When the number of the first sub-flow channels is at least two, the number of the first sub-flow channels is the same as the number of the second sub-flow channels.

[0030] In the technical solution of the present application, by setting the number of second sub-flow channels to multiple, and surrounding the outer wall of the mixing flow channel, the additive in the second sub-flow channel can enter the mixing flow channel along different directions and can be mixed with the concrete in the mixing flow channel in different directions, thereby further improving the mixing uniformity.

[0031] In some technical solutions of the present application, the concrete nozzle also includes: an additive input pipe, connected to the body and communicated with the additive input flow channel; a concrete input pipe, connected to the body and communicated with the concrete input flow channel.

[0032] In the technical solution of the present application, the concrete nozzle includes an additive input pipe and a concrete input pipe, both of which are connected to the body, and the additive input pipe is connected to the additive input flow channel, and the concrete input pipe is connected to the concrete input flow channel.

[0033] In some technical solutions of the present application, the inner diameter of the inlet of the output flow channel is larger than the inner diameter of the outlet of the output flow channel.

[0034] In the technical solution of the present application, the inner diameter of the inlet of the output flow channel is larger than the inner diameter of the outlet of the output flow channel, so that the mixed concrete and additives can be accelerated in the output flow channel, increasing the speed of the concrete and additives sprayed out of the nozzle after mixing, so that the mixed concrete and additives can be accelerated again in the output flow channel, thereby improving the spraying effect.

[0035] According to the second aspect of the utility model, a spraying assembly is proposed, including a concrete spray head in any of the above technical solutions, and thus has all the beneficial technical effects of the concrete spray head in any of the above technical solutions, which will not be described in detail here.

[0046] Refer to the following Figures 1 to 3 A concrete spray head 100 and a spray assembly 200 according to some embodiments of the present invention are described.

[0047] Figure 1 One of the structural schematic diagrams of the concrete sprinkler provided in some embodiments of the present application is shown. Figure 2 FIG. 2 shows a second structural schematic diagram of a concrete sprinkler provided in some embodiments of the present application. Figure 1 and Figure 2 As shown, a first embodiment of the utility model provides a concrete sprinkler 100, comprising: a body 110 and a spoiler 120 arranged in the body 110, wherein a concrete input flow channel 112, an additive input flow channel 114, a mixing flow channel 116 and an output flow channel 118 are arranged in the middle of the body 110, wherein one end of the mixing flow channel 116 is connected to the concrete input flow channel 112, the other end of the mixing flow channel 116 is connected to the inlet of the output flow channel 118, and the additive input flow channel 114 is connected to the side wall of the mixing flow channel 116; the spoiler 120 is arranged in the mixing flow channel 116, and the spoiler 120 is used to spoil the fluid in the mixing flow channel 116.

[0048] In this embodiment, a plurality of interconnected flow channels are provided in the body 110, including a concrete input flow channel 112, which is located at a first end of the body 110, an output flow channel 118 is located at the other end of the body 110, a mixing flow channel 116 is located between the concrete input flow channel 112 and the output flow channel 118, and an additive input flow channel 114 is connected to the mixing flow channel 116 through a side wall of the mixing flow channel 116.

[0049] The concrete input channel 112 is connected to an external concrete pipeline, and the concrete pipeline inputs concrete into the mixing channel 116 through the concrete input channel 112. The additive input pipe 130 is connected to the external additive pipeline, and the additive flows through the additive input channel 114 through the additive input pipe 130 and enters the mixing channel 116. The additive and concrete are mixed in the mixing channel 116 and then transmitted to the output channel 118, and then sprayed out of the concrete nozzle 100 through the output channel 118.

[0050] In this embodiment, a spoiler 120 is provided in the mixing flow channel 116. When the additive and concrete flow through the spoiler 120 of the mixing flow channel 116, they can be fully mixed in the mixing flow channel 116 driven by the spoiler 120, thereby improving the mixing degree of the concrete and additive in the mixing flow channel 116 and avoiding the problem of poor concrete spraying effect caused by insufficient mixing.

[0051] Exemplarily, the additives inputted by the additive input pipe 130 include, but are not limited to, quick-setting agents, reinforcing agents, antifreeze agents, waterproofing agents, and the like.

[0052] In the embodiment of the present application, by providing a concrete input flow channel 112, an additive input flow channel 114, a mixing flow channel 116 and an output flow channel 118 in the body 110 of the concrete sprinkler 100, the concrete in the concrete input flow channel 112 and the additive in the additive input flow channel 114 can be mixed in the mixing flow channel 116, and by providing a spoiler 120 in the mixing flow channel 116, when the concrete, the additive and the mixture flow through the spoiler 120, they can move under the turbulent effect of the spoiler 120, thereby improving the uniform mixing process of the additive and the concrete, and there is no need to provide a stirring component that requires an additional power source, thereby improving the convenience of the staff in using the concrete sprinkler 100, and there is no need to frequently perform daily maintenance and care.

[0053] In some embodiments of the present application, the spoiler 120 includes: a column 122 disposed in the mixing channel 116 , and the axis of the column 122 coincides with the axis of the mixing channel 116 ; and a spoiler rib 124 disposed on the outer wall of the column 122 .

[0054] In this embodiment, the spoiler 120 includes a column 122 and a spoiler rib 124. The column 122 is disposed in the mixing flow channel 116 and extends along the axial direction of the mixing flow channel 116. The spoiler rib 124 is disposed on the outer side wall of the column 122 and is spiral. The spiral spoiler rib 124 disposed on the column 122 and the inner side wall of the mixing flow channel 116 form a spoiler space. When the mixed concrete and additives flow through the spoiler space, a vortex can be formed in the spoiler space, thereby improving the mixing uniformity between the concrete and the additives.

[0055] like Figure 1 As shown, in this embodiment, the extension direction of the column 122 matches the extension direction of the axis A of the mixing channel 116 .

[0056] Exemplarily, the column 122 and the spoiler rib 124 are integrally formed, and the column 122 and the spoiler rib 124 can be made of a polymer material or a metal material.

[0057] In the embodiment of the present application, the spoiler 120 includes a column 122 whose extension direction matches the axial extension direction of the mixing channel 116, and a spoiler rib 124 arranged on the column 122, forming a spoiler space between the spoiler 120 and the inner wall of the mixing channel 116, so that the mixture flowing through can form a vortex, further improving the mixing uniformity of the concrete and the additive.

[0058] like Figure 1 As shown, in some embodiments of the present application, the spoiler rib 124 is spirally wound around the outer wall of the column 122 .

[0059] In this embodiment, the spoiler ribs 124 are spirally wound on the outer wall of the column 122. The spiral shape of the spoiler ribs 124 makes the spoiler space formed between the column 122 and the mixing channel 116 also spiral, that is, the mixture of concrete and additives entering the mixing channel 116 can flow in a spiral shape, thereby improving the mixing uniformity of the concrete and additives.

[0060] Exemplarily, the size of the spoiler 124 gradually decreases in the direction from the first end of the column 122 to the second end of the column 122 , the first end of the column 122 is an end close to the concrete input flow channel 112 , and the second end of the column 122 is an end close to the output flow channel 118 .

[0061] Exemplarily, the size of the spoiler 124 gradually increases and then gradually decreases in the direction from the first end of the column 122 to the second end of the column 122. The first end of the column 122 is an end close to the concrete input flow channel 112, and the second end of the column 122 is an end close to the output flow channel 118.

[0062] In the above embodiment, the size of the spoiler rib 124 is the size of the spoiler rib 124 protruding from the outer wall of the column 122 . By limiting the size of the spoiler rib 124 , the mixing degree of concrete and additives in the mixing channel 116 can be further improved.

[0063] like Figure 2 As shown, in some embodiments of the present application, the spoiler 120 includes: an isolator 126, which is arranged in the mixing flow channel 116 and is located at one end of the mixing flow channel 116 close to the concrete input flow channel, and at least two channels 128 are opened on the isolator 126, wherein the concrete input flow channel and the mixing flow channel 116 are connected through the at least two channels 128.

[0064] In this embodiment, the spoiler 120 includes an isolator 126 provided with a channel 128. The two sides of the isolator 126 are respectively the concrete input flow channel 112 and the mixing flow channel 116. The channel 128 provided on the isolator 126 connects the concrete input flow channel 112 and the mixing flow channel 116, that is, the concrete in the concrete input flow channel 112 needs to flow through the channel 128 on the isolator 126 to enter the mixing flow channel 116. Since the number of channels 128 provided on the isolator 126 is at least two, the concrete enters the mixing flow channel 116 through multiple channels 128, that is, the direction in which the concrete enters the mixing flow channel 116 is relatively dispersed, which is convenient for mixing with the additives entering the mixing flow channel 116.

[0065] Exemplarily, at least two channels 128 are evenly spaced on the isolation member 126 , so that when the concrete flows through the at least two channels 128 on the isolation member 126 , it can evenly enter the mixing channel 116 , thereby improving the mixing effect of the concrete and the additive in the mixing channel 116 .

[0066] In the embodiment of the present application, the spoiler 120 is set as an isolation piece 126 with a channel 128, so that when the concrete flows through the isolation piece 126, it needs to enter the mixing channel 116 through the channel 128, so that the concrete enters the mixing channel 116 in a relatively dispersed state, which is convenient for mixing with the additive in the mixing channel 116, thereby improving the mixing adequacy of the concrete and the additive in the mixing channel 116.

[0067] In some embodiments of the present application, the isolation member 126 is a columnar structure, at least two channels 128 extend from one plane of the isolation member 126 to another plane, and the extension direction of the at least two channels 128 is not parallel to the axis of the isolation member 126 .

[0068] In the embodiment of the present application, by setting the axes of at least two channels 128 and the axis of the isolation member 126 to be non-parallel to each other, the concrete flowing through the at least two channels 128 can enter the mixing channel 116 in different directions, further improving the mixing effect of the concrete and the additive in the mixing channel 116.

[0069] like Figure 2 As shown, in some embodiments of the present application, the auxiliary agent input channel 114 includes: a first sub-channel 1142; a second sub-channel 1144, the first ends of the second sub-channels 1144 are connected to the first sub-channel 1142, the second ends of the second sub-channels 1144 are connected to the mixing channel 116 through the side wall of the mixing channel 116, and the flow area of ​​the first sub-channel 1142 is greater than the flow area of ​​the second sub-channel 1144.

[0070] In this embodiment, the additive input channel 114 includes a first sub-channel 1142 and a second sub-channel 1144, and the second sub-channel 1144 is located between the first sub-channel 1142 and the mixing channel 116, and the additive in the first sub-channel 1142 flows into the mixing channel 116 through the second sub-channel 1144. By setting the flow area of ​​the first sub-channel 1142 to be larger than the flow area of ​​the second sub-channel 1144, the second sub-channel 1144 can pressurize the additive flowing through, so that the additive entering the mixing channel 116 has a higher flow potential energy, thereby improving the mixing effect of the additive and concrete in the mixing channel 116.

[0071] In the embodiment of the present application, the additive input channel 114 is designed to be a two-section channel including a first sub-channel 1142 and a second sub-channel 1144, and the communication area of ​​the second sub-channel 1144 directly connected to the mixing channel 116 is larger than the communication area of ​​the first sub-channel 1142, so that when the additive flows through the first sub-channel 1142 and the second sub-channel 1144 in sequence under a certain driving force, the additive can be accelerated in the second sub-channel 1144, so that the additive enters the mixing channel 116 at a higher flow rate, thereby further improving the mixing effect of the additive and concrete.

[0072] like Figure 2 As shown, in some embodiments of the present application, the number of the second sub-channels 1144 is at least two, and the second ends of the second sub-channels 1144 are distributed around the side wall of the mixing channel 116 .

[0073] In this embodiment, the number of second sub-channels 1144 is at least two, and the second ends of at least two second sub-channels 1144 are distributed around the side wall of the mixing channel 116. The second end of the second sub-channel 1144 is an end connected to the mixing channel 116. By surrounding and connecting the second ends of at least two second sub-channels 1144 to the side wall of the mixing channel 116, the additive in the second sub-channel 1144 can enter the mixing channel 116 in different directions and positions, further improving the mixing effect of the additive entering the mixing channel 116 and the concrete.

[0074] Exemplarily, there are eight second sub-flow channels 1144, and each two second sub-flow channels 1144 form a group, for a total of four groups of second sub-flow channels 1144. The second end of one group of second sub-flow channels 1144 is arranged along the axial direction of the mixing flow channel 116, and the four groups of second sub-flow channels 1144 are arranged along the circumferential direction of the mixing flow channel 116.

[0075] In this embodiment, the number of first sub-channels 1142 may be one or at least two. When the number of first sub-channels 1142 is at least two, the number of first sub-channels 1142 is the same as the number of second sub-channels 1144 .

[0076] In the embodiment of the present application, by setting the number of second sub-flow channels 1144 to be multiple, and surrounding the outer wall of the mixing channel 116 with multiple second sub-flow channels 1144, the additive in the second sub-flow channel 1144 can enter the mixing channel 116 along different directions, and can be mixed with the concrete in the mixing channel 116 in different directions, thereby further improving the mixing uniformity.

[0077] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the concrete nozzle 100 further includes: an additive input pipe 130 connected to the body 110 and communicated with the additive input flow channel 114; and a concrete input pipe 140 connected to the body 110 and communicated with the concrete input flow channel 112.

[0079] Exemplarily, both the additive input pipe 130 and the concrete input pipe 140 are provided with connectors, and can be connected to external pipelines through the connectors.

[0080] Exemplarily, the inner diameter of the additive input pipe 130 is smaller than the inner diameter of the concrete input pipe 140 .

[0081] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the inner diameter of the inlet of the output flow channel 118 is greater than the inner diameter of the outlet of the output flow channel 118 .

[0082] In the embodiment of the present application, the inner diameter of the inlet of the output flow channel 118 is larger than the inner diameter of the outlet of the output flow channel 118, so that the mixed concrete and additives can be accelerated in the output flow channel 118, thereby increasing the speed at which the concrete and additives are sprayed out of the nozzle after being mixed, and allowing the mixed concrete and additives to be accelerated a second time in the output flow channel 118, thereby improving the spraying effect.
