Description

Technical Field

[0001] This application relates to the field of wet spraying machine technology, and specifically to a composite distribution plate for a wet spraying machine. Background Technology

[0002] The distribution plate of the wet shotcrete machine is an important component of the spraying section. It is used to mix the accelerator and compressed air in the distribution plate and then transport the mixed medium to the mixer of the nozzle, where it is mixed with the concrete.

[0003] When the distribution plate is working, it delivers the accelerator and mixes it with compressed air before delivering it to the mixer. The distribution plate is in contact with the accelerator for a long time, and the accelerator is corrosive. Therefore, most existing distribution plates are made of stainless steel to improve the corrosion resistance of the distribution plate.

[0004] However, most existing distribution plates are integrally molded and made entirely of stainless steel, which makes them heavy and increases energy consumption during equipment operation. Furthermore, the accelerator rubs against the distribution plate for a long time, and stainless steel has poor wear resistance, resulting in poor wear resistance of the distribution plate and a shorter service life.

[0005] Based on the above, the distribution plate of the wet spraying machine in the prior art has room for further improvement. Utility Model Content

[0006] In view of this, and in response to the technical problem that the distribution plate in the prior art is made of stainless steel in one piece, resulting in excessive weight, this application provides a composite distribution plate for a wet spraying machine, which adopts a split structure, including a plate body and a connector body. The connector body is disposed on the plate body and is used to transport the accelerator and compressor into the plate body and to transport the mixing medium into the mixer. The plate body is made of non-metallic material, which can reduce the overall weight of the distribution plate.

[0007] This application provides a composite distribution plate for a wet spraying machine, comprising:

[0008] The disk body has at least four mounting cavities;

[0009] The first connector body is configured as one and is located inside the mounting cavity for conveying compressed air;

[0010] There are three second connector bodies, which are located in the installation cavity and communicate with the first connector body; one of the second connector bodies is used to convey the accelerator, and the other two second connector bodies are used to convey the mixed medium formed by the accelerator and compressed air.

[0011] The material used to make the disc body is different from that used to make the first connector body and the second connector body; the disc body is made of non-metallic material.

[0012] Compared with the prior art, the composite distribution plate for wet spraying machine of this application adopts a split structure, which divides the distribution plate into a connector body and a plate body. The connector body is set in the plate body, so that the plate body and the connector body can be made of different materials. The plate body is made of non-metallic material, thereby reducing the overall weight of the distribution plate and reducing the wear and tear during equipment operation. The plate body is provided with mounting cavities for installing the first connector body and the second connector body. The first connector body is used to deliver compressed air into the plate body. One of the second connector bodies delivers the accelerator to the plate body to mix with the compressed air to form a mixing medium, which is then delivered to the mixer through the other two second connector bodies to mix with the concrete.

[0013] Preferably, the first connector body and the second connector body are made of metal material;

[0014] The first connector body and the second connector body are made of the same material or different materials.

[0015] In this embodiment, the first connector and the second connector need to transport the medium and connect with each medium transport device. Therefore, they are made of metal materials, which can provide a certain degree of corrosion resistance and high load-bearing capacity to ensure the stability of the connection between the distribution plate and other devices.

[0016] Preferably, the metal material includes any one of stainless steel, high-quality carbon steel, and alloy steel;

[0017] The first connector body is made of either high-quality carbon steel or alloy steel.

[0018] The second connector body is made of any one of the following materials: 304 stainless steel, 316 stainless steel, and 316L stainless steel.

[0019] In this embodiment, the first connector is used to transport compressed air, which has low corrosiveness and can be made of a different material than the second connector; while the second connector is in contact with the quick-setting agent and is preferably made of stainless steel. By using different materials for the first and second connectors, it is possible to ensure that both connectors meet the working requirements while saving costs to a certain extent.

[0020] Preferably, the Shore hardness value of the non-metallic material is 60A-70A;

[0021] The non-metallic material is either polyurethane or rubber.

[0022] In this embodiment, the disc body is made of polyurethane or rubber, which gives the disc body good wear resistance and corrosion resistance, as well as shock absorption and noise reduction, and the overall weight is relatively light.

[0023] Preferably, the mounting cavity is divided into:

[0024] The first mounting cavity is configured as one, arranged along the axis, and is used to mount the first connector body;

[0025] The second mounting cavity is configured as three in a radial arrangement for mounting the second connector;

[0026] The first mounting cavity and the second mounting cavity are connected at their ends near the center of the distribution plate.

[0027] In this embodiment, the first mounting cavity and the second mounting cavity are used to install the first connector body and the second connector body respectively, so as to ensure the stability of the connection between the first connector body, the second connector body and the disc body.

[0028] Preferred options also include:

[0029] The first engaging rib is provided on the radial sidewall of the first mounting cavity and protrudes radially toward the central axis of the first mounting cavity; there are at least two ribs, and they are spaced apart along the axial direction of the first mounting cavity;

[0030] The first engagement groove is provided on the radial outer side wall of the first connector body and is used to engage with the first engagement protrusion.

[0031] In this embodiment, after the first engaging protrusion and the first engaging groove are engaged, the connection between the first connector body and the disc body can be limited in the axial direction to improve the connection stability between the first connector body and the disc body, making it difficult for the first connector body to separate from the disc body in the axial direction.

[0032] Preferred options also include:

[0033] The second engagement rib is provided on the radial sidewall of the second mounting cavity and protrudes radially toward the central axis of the second mounting cavity; there are at least two ribs, and they are distributed at intervals along the axial direction of the second mounting cavity;

[0034] The first engagement groove is provided on the radial outer side wall of the second connector body and is used to engage with the second engagement protrusion.

[0035] In this embodiment, after the second engaging protrusion and the second engaging groove are engaged, they can limit the connection between the second connector body and the disc body in the axial direction, so as to improve the connection stability between the second connector body and the disc body and make it difficult for the second connector body to separate from the disc body in the axial direction.

[0036] Preferred options also include:

[0037] The third engagement protrusion is provided on the axial sidewall of the second mounting cavity and protrudes axially away from the disc body.

[0038] The third engagement groove is located on the axial outer side wall of the second connector body and is used to engage with the third engagement protrusion.

[0039] In this embodiment, the third engaging protrusion and the third engaging groove cooperate to limit the connection between the second connector body and the disc body in the radial direction, making it difficult for the second connector body to be misaligned with the disc body in the radial direction.

[0040] Preferred options also include:

[0041] The first conveying cavity is located on the first connector body and is coaxially arranged with the first mounting cavity;

[0042] The second conveying cavity is located on the second connector body and is coaxially arranged with the second mounting cavity;

[0043] The mixing chamber, located at the center of the disc, is used to provide a mixing space for the accelerator and compressed air;

[0044] A connecting thread is provided on the inner side wall of the second conveying chamber;

[0045] The first conveying cavity, the second conveying cavity, and the mixing cavity are connected, and the inner diameter of the mixing cavity is larger than the inner diameter of the first conveying cavity and the second conveying cavity.

[0046] In this embodiment, the inner diameter of the mixing chamber is larger than that of the first conveying chamber and the second conveying chamber, thereby making the mixing chamber larger and providing a sufficiently large mixing space for compressed air and accelerator, so that the two can be fully mixed, reducing the probability of pressure buildup, thereby ensuring the uniformity of mixing of the mixing medium and concrete, ensuring the continuity and stability of the lift of the concrete sprayed by the wet spraying machine, and thus reducing the concrete drop rate and rebound rate.

[0047] Preferably, the mixing chamber includes:

[0048] The upper cavity has a spherical structure, and its inner diameter is larger than the inner diameters of the first and second conveying cavities.

[0049] The lower cavity is an annular structure and is axially connected to one end of the upper cavity; along the axial direction, the inner diameter of the lower cavity gradually decreases in the direction away from the upper cavity;

[0050] Among them, the three second conveying chambers are connected to the upper cavity, and the first conveying chamber is connected to the lower cavity.

[0051] In this embodiment, the mixing chamber consists of two cavities, an upper cavity with a spherical structure and a lower cavity with a ring structure. The inner walls of both cavities are smooth curved surfaces. The second conveying cavity is connected to the upper cavity, and the lower cavity is connected to the first conveying cavity. This allows the compressed air and the accelerator to interact with the mixing chamber at different positions, providing sufficient space for the compressed air and the accelerator to circulate and increase the uniformity of their mixing.

[0063] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0066] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 6 illustrate.

[0067] This application provides a composite distribution plate 1 (hereinafter referred to as distribution plate 1) for a wet shotcrete machine, which is used to mix a quick-setting agent with compressed air to form a mixing medium, and to transport the mixing medium into a mixer to mix with concrete, and then spray it out through the spraying mechanism of the wet shotcrete machine.

[0068] Specifically, such as Figures 1 to 6 As shown, the distribution plate 1 has a regular hexagonal structure. The distribution plate 1 adopts a split structure, including a plate body 11 and a connector body. The plate body 11 is provided with a mounting cavity for installing the connector body. The connector body is set in the mounting cavity of the plate body 11 and is fixedly connected to the mounting cavity. This allows the plate body 11 and the connector body to be made of different materials. The plate body 11 is made of non-metallic material, thereby reducing the overall weight of the distribution plate 1, reducing the wear and tear during equipment operation, and reducing the manufacturing cost of the plate body 11.

[0069] Among them, such as Figures 3 to 6 As shown, the connector body is divided into a first connector body 12 and a second connector body 13. The first connector body 12 is set as one, which is used to deliver compressed air into the disc body 11. The second connector body 13 is set as three. One of the second connector bodies 13 delivers the accelerator into the disc body 11 and mixes it with the compressed air to form a mixing medium. Then, it is delivered to the mixer through the other two second connector bodies 13 to mix with the concrete.

[0070] In this application, the non-metallic material used for the disc 11 has a Shore hardness of 60A to 70A, which gives the disc 11 both elasticity and hardness, thereby improving its wear resistance and corrosion resistance, and thus extending its service life. The disc 11 is made of either polyurethane or rubber to ensure the stability of the fit between the first connector 12, the second connector 13, and the disc 11.

[0071] The rubber material can be any one of ethylene propylene rubber, chlorosulfonated polypropylene rubber, acid acrylate rubber, polyurethane rubber, silicone rubber, fluororubber, polysulfide rubber, or chlorinated polyethylene rubber.

[0072] The distribution plate 1 of this application adopts a split structure and combines non-metallic and metallic materials to form a composite distribution plate 1, which can improve the corrosion resistance of the composite distribution plate 1, increase its service life, and make the overall weight of the distribution plate 1 lighter.

[0073] like Figures 3 to 6 As shown, there are four mounting cavities, which are divided into a first mounting cavity 111 and a second mounting cavity 112. The first mounting cavity 111 is one, which is arranged along the axis for mounting the first connector body 12. The first connector body 12 is coaxial with the first mounting cavity 111. There are three second mounting cavities 112, which are all arranged radially and are equidistantly distributed along the same circumference. The included angle between the central axes of two adjacent second mounting cavities 112 is 120 degrees. The second connector is coaxial with the second mounting cavity 112, and the three second mounting cavities 112 are used to mount the three second connectors. In this embodiment, the ends of the first mounting cavity 111 and the second mounting cavity 112 near the center of the distribution plate 1 are connected. Therefore, the axial length of the first connector is less than the axial length of the first mounting cavity 111, and the axial length of the second connector is less than the length of the second mounting cavity 112, so that the medium transported by the first connector body 12 and the second connector body 13 can be mixed at the connection between the first mounting cavity 111 and the second mounting cavity 112.

[0074] The first connector body 12 is provided with a first conveying cavity 121, which is coaxially arranged with the first mounting cavity 111. The inner diameter of the first conveying cavity 121 is smaller than the inner diameter of the first mounting cavity 111. The first conveying cavity 121 is connected to the pipe joint of the compressed air device for the supply of compressed air. The second connector body 13 is provided with a second conveying cavity 131, which is coaxially arranged with the second mounting cavity 112. The inner diameter of the second conveying cavity 131 is smaller than the inner diameter of the second mounting cavity 112. The second conveying cavity 131 is used to connect to the pipe joint of the accelerator device and the mixer. The inner side wall of the second conveying cavity 131 is provided with a connecting thread, which makes it easier to connect the second connector body 13 to the pipe joint of the accelerator device and the mixer.

[0075] In this application, since the first connector body 12 and the second connector body 13 need to transport the medium and connect with various medium transport devices, both the first connector body 12 and the second connector body 13 are made of metal materials, which can play a certain anti-corrosion role, and have high load-bearing capacity and strength, ensuring that the structural strength of the connecting threads on the first connector body 12 and the second connector body 13 is not easily worn, thereby ensuring the connection stability of the distribution plate 1 with other devices; and after being made of metal materials, the first connector body 12 and the second connector body 13 have a strong ability to withstand the pressure of compressed air and quick-setting agent, and will not easily fall off the first connector body 12 and the second connector body 13 due to excessive pressure.

[0076] The first connector body 12 and the second connector body 13 can be made of any one of high-quality carbon steel, alloy steel, or stainless steel.

[0077] In an optional embodiment of this application, the first connector body 12 and the second connector body 13 are made of the same metal material.

[0078] In another optional embodiment of this application, the first connector body 12 and the second connector body 13 are made of different metal materials. Specifically, the first connector body 12 is used to transport compressed air, which is less corrosive. Therefore, the first connector body 12 can be made of a different material than the second connector body 13 to ensure that both connector bodies meet the working requirements while saving costs to a certain extent. Since the price of stainless steel is more than three times that of ordinary carbon structural steel, using carbon steel for the first connector body 12 can reduce costs.

[0079] The first connector body 12 is made of any one of high-quality carbon steel or alloy steel; the second connector body 13 is made of any one of 304 stainless steel, 316 stainless steel or 316L stainless steel. Stainless steel has good corrosion resistance, oxidation resistance, strength and toughness, and is easy to process with connecting threads.

[0080] Based on the above embodiments, the distribution plate 1 is further extended; such as... Figures 3 to 6As shown, the distribution plate 1 is provided with a mixing chamber 116, which is located at the center of the plate body 11 and at the connection between the first mounting chamber 111 and the second mounting chamber 112. The mixing chamber 116 is used to provide a mixing space for the accelerator and compressed air. The inner diameter of the mixing chamber 116 is larger than the inner diameter of the first conveying chamber 121 and the second conveying chamber 131, so that the space of the mixing chamber 116 is larger, which can provide a large enough mixing space for the compressed air and the accelerator, so that the two can be fully mixed, reducing the probability of pressure buildup, thereby ensuring the uniformity of the mixing medium and the concrete, ensuring the continuity and stability of the head of the concrete sprayed by the wet spraying machine, and thus reducing the concrete drop rate and rebound rate.

[0081] In this application, as Figure 2 As shown, the outlet of any one of the second conveying chambers 131 corresponds to the side wall between the other two second conveying chambers 131. When the accelerator is conveyed from the second conveying chamber 131 to the mixing chamber 116, it will first act on the inner wall of the mixing chamber 116 and will not flow directly into the other two second conveying chambers 131. This can increase the residence time of the accelerator in the mixing chamber 116, thereby improving the mixing effect.

[0082] Furthermore, such as Figures 3 to 6As shown, the mixing chamber 116 includes an upper chamber 1161 and a lower chamber 1162. The upper chamber 1161 has a spherical structure, and the lower chamber 1162 has an annular structure. The inner walls of both the upper chamber 1161 and the lower chamber 1162 are smooth curved surfaces to reduce the obstruction of the flow of compressed air and accelerator, ensuring their smooth flow. The upper axial end of the lower chamber 1162 is connected to the upper chamber 1161, and the connection between the two is an arc transition to reduce stress concentration. The lower axial end of the lower chamber 1162 is connected to the first conveying chamber 121. The upper chamber 1161, the lower chamber 1162, and the first conveying chamber 121 are coaxially arranged. When compressed air enters the mixing chamber 116 from the first conveying chamber 121, the compressed gas first rushes to the top of the upper chamber 1161, and then flows downward from the top of the upper chamber 1161 to the surrounding curved surfaces. During this flow process, the noise generated by the compressed air flow can be reduced. Three second conveying chambers 131 are connected to the upper cavity 1161 and are arranged radially along the upper cavity 1161. When the accelerator enters the mixing chamber 116 through the second conveying chambers 131, it first acts on the side wall of the upper cavity 1161, and then flows towards the top of the upper cavity 1161 and the lower cavity 1162, respectively. Therefore, the combination of the mixing chamber 116 with the first conveying chamber 121 and the second conveying chambers 131 increases the flow space of the accelerator and compressed air in the mixing chamber 116, thereby making the two mix more evenly and reducing the noise during mixing and the probability of pressure buildup. In addition, since a non-metallic material is used, it has a certain degree of elasticity, which further reduces noise when the compressed air and accelerator come into contact with its disc 11.

[0083] Based on the above embodiments, the connection between the first connector body 12 and the disc body 11 is further extended; such as... Figures 4 to 6 As shown, the first mounting cavity 111 is provided with a first engaging protrusion 113. The first engaging protrusion 113 is disposed on the radial side wall of the first mounting cavity 111 and protrudes radially toward the central axis of the first mounting cavity 111. The first engaging protrusion 113 has an annular structure. There are at least two first engaging protrusions 113, and the first engaging protrusions 113 are distributed at intervals along the axial direction of the first mounting cavity 111 to increase the limiting connection position with the first connector body 12. The radial outer side wall of the first connector body 12 is provided with a first engaging groove. The number and structure of the first engaging grooves correspond to the first engaging protrusions 113. The first engaging grooves are used to engage with the first engaging protrusions 113 to realize the axial connection limiting between the first connector body 12 and the disc body 11, thereby improving the connection stability between the first connector body 12 and the disc body 11 and making it difficult for the first connector body 12 to axially disengage from the first mounting cavity 111 of the disc body 11, thus ensuring the working stability of the distribution disc 1.

[0084] Based on the above embodiments, the connection between the second connector body 13 and the disc body 11 is further extended; such as... Figures 3 to 6 As shown, a second engaging protrusion 114 is provided on the radial sidewall of the second mounting cavity 112. The second engaging protrusion 114 protrudes radially toward the central axis of the second mounting cavity 112. The second engaging protrusion 114 has an annular structure, and there are at least two second engaging protrusions 114. The second engaging protrusions 114 are distributed at intervals along the axial direction of the second mounting cavity 112 to increase the limiting connection position with the first connector body 12. The radial outer sidewall of the second connector body 13 is provided with a second engaging groove. The number and structure of the second engaging grooves correspond to the second engaging protrusions 114. The second engaging grooves are used to engage with the second engaging protrusions 114 to realize the axial connection limiting between the second connector body 13 and the disc body 11, thereby improving the connection stability between the second connector body 13 and the disc body 11 and making it difficult for the second connector body 13 to axially disengage from the second mounting cavity 112 of the disc body 11, thus ensuring the working stability of the distribution disc 1.

[0085] Furthermore, such as Figures 3 to 6 As shown, a third engaging ridge 115 is provided on the axial sidewall of the second mounting cavity 112. The third engaging ridge 115 protrudes axially away from the center of the disc body 11. The third engaging ridge 115 has a ring structure, and there is at least one third engaging ridge 115. When the number of third engaging ridges 115 is greater than one, the third engaging ridges 115 are arranged on the same plane, and the inner diameter of each third engaging ridge 115 is different. There is a radial gap between two adjacent third engaging ridges 115. The minimum inner diameter of 5 is greater than the inner diameter of the second conveying cavity 131; correspondingly, the axial outer side wall of the second connector body 13 is provided with a third meshing groove. The number and structure of the third meshing groove correspond to the third meshing protrusion 115. The third meshing groove is used to mesh with the third meshing protrusion 115 to realize the connection limit between the second connector body 13 and the second mounting cavity 112 of the disc body 11 in the radial direction, so that the second connector body 13 is not easily misaligned with the second mounting cavity 112 of the disc body 11 in the radial direction, thereby ensuring the working stability of the distribution disc 1.

[0086] In this application, the cross-sectional shapes of the first engaging protrusion 113, the second engaging protrusion 114, and the third engaging protrusion 115 include, but are not limited to, semi-circular, triangular, rectangular, and trapezoidal shapes.
