Description

Technical Field

[0001] This utility model relates to the field of cement product manufacturing technology, and in particular to a slurry coating device for cement product manufacturing. Background Technology

[0002] Cement products are non-metallic building materials made with cement as the main binder, combined with aggregates, water and additives. During their manufacturing process, a spraying machine is needed to spray functional or decorative coatings onto their surfaces.

[0003] A mortar spraying machine disclosed in Chinese patent CN221664178U filters the raw materials entering the mortar tank through a screen. Because the screen is tilted, its filtration area is further increased. The screen filters the coating material entering the mortar tank to ensure normal operation of the equipment and a smooth sprayed surface. However, according to the mortar spraying machine provided by related technologies and existing technology, when spraying mortar with different viscosities, different nozzle diameters need to be changed. Managing and replacing multiple nozzle sizes is inconvenient. Furthermore, when spraying mortar with different viscosities, the operator needs to adjust the output air pressure of the spraying machine according to the viscosity of the mortar. Manual adjustment is greatly affected by the operator's experience; too low a pressure can easily lead to uneven atomization, while too high a pressure can easily lead to mortar splattering. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a slurry coating device for cement product manufacturing.

[0005] The objective of this utility model is achieved through the following technical solution: a slurry coating device for cement product manufacturing, comprising a spraying machine, wherein a material conveying pipe is installed at the slurry output end of the spraying machine, and a gas conveying pipe is installed at the gas output end of the spraying machine. A gun assembly is installed at the end of the material conveying pipe away from the spraying machine. An adjusting component for controlling the opening size of the gun assembly is fixedly provided inside the gun assembly. A feedback component for pushing the adjusting component is fixedly provided on one side of the adjusting component. A control component for controlling the output pressure of the spraying machine is provided on the bottom side of the feedback component away from the adjusting component.

[0006] Preferably, the gun body assembly includes a gun body fixed to one end of the feed pipe. The top of the gun body has a feed channel communicating with the feed pipe. The gun body has an air supply channel communicating with the air supply pipe located below the feed channel. One end of the air supply channel inside the gun body is connected to a mounting cavity. The end of the mounting cavity away from the air supply channel is connected to a mixing cavity. The mixing cavity is communicating with the feed channel. The end of the mixing cavity away from the mounting cavity has a conical cavity. The end of the conical cavity away from the mixing cavity has a spray hole.

[0007] Preferably, the adjusting assembly includes a piston cylinder fixed inside the mounting cavity. An inner cavity is formed at the center of the piston cylinder, and an inner piston is slidably installed inside the inner cavity. An adjusting rod is fixedly provided on the side of the inner piston near the conical cavity. The adjusting rod is slidably connected to the piston cylinder, and its end away from the inner piston extends into the conical cavity. A spring is provided on the side of the inner piston away from the adjusting rod. An outer cavity is formed outside the inner cavity, and both ends of the inner cavity and the outer cavity are connected. An outer piston is slidably installed inside the outer cavity, and four push rods are fixedly provided on the side of the outer piston away from the conical cavity. All four push rods extend outside the piston cylinder.

[0008] Preferably, the feedback component includes a push plate fixed to one end of the four push rods, a sealing plate fixedly provided on the top of the push plate, and a baffle fixedly provided on the top of the sealing plate.

[0011] Preferably, the baffle is located inside the material conveying channel, has a circular cross-section, a slope at the top, and a semi-circular through hole at the bottom.

[0012] Beneficial effects:

[0013] This slurry coating device for cement product manufacturing incorporates an adjustment component, a feedback component, and a control component. The feedback component, driven by the slurry, controls the adjustment component to adjust the spray nozzle diameter. This ensures that the larger the slurry viscosity, the larger the spray nozzle diameter, eliminating the need to replace nozzles with different diameters and reducing the number of nozzles that need to be managed.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 7 As shown, a slurry coating device for cement product manufacturing includes a sprayer 1. A feed pipe 2 is installed at the slurry output end of the sprayer 1, and a gas supply pipe 3 is installed at the gas output end of the sprayer 1. A gun assembly 4 is installed at the end of the feed pipe 2 away from the sprayer 1. An adjustment component 5 for controlling the opening size of the gun assembly 4 is provided inside the gun assembly 4. A feedback component 6 for pushing the adjustment component 5 is fixedly provided on one side of the adjustment component 5. A control component 7 for controlling the output pressure of the sprayer 1 is provided on the bottom side of the feedback component 6 away from the adjustment component 5. The slurry in the sprayer 1 enters the gun assembly 4 through the feed pipe 2, and so on. High-pressure airflow enters the gun assembly 4 through the air supply pipe 3 and mixes with the slurry. Then, it is sprayed out from the gun assembly 4 for spraying. During this process, the feedback component 6 is pushed by the slurry and the control adjustment component 5 automatically adjusts the opening size of the gun assembly 4. The greater the viscosity of the slurry, the greater the thrust on the feedback component 6, which makes the control adjustment component 5 control the opening of the gun assembly 4 to become larger, automatically adapting to slurries of different viscosities. At the same time, the feedback component 6 also pulls the control component 7, which adjusts the gas output pressure of the sprayer 1 to ensure that the gas output pressure matches the viscosity of the slurry and improves the spraying effect.

[0026] like Figure 1 and Figure 2 As shown, the gun body assembly 4 includes a gun body 401 fixed to one end of the feed pipe 2. A feed channel 402 communicating with the feed pipe 2 is opened at the top of the gun body 401. An air supply channel 403 communicating with the air supply pipe 3 is opened below the feed channel 402 inside the gun body 401. One end of the air supply channel 403 inside the gun body 401 is connected to a mounting cavity 404. The end of the mounting cavity 404 away from the air supply channel 403 is connected to a mixing cavity 405. The mixing cavity 405 communicates with the feed channel 402. A conical cavity 406 is provided at the end of 405 away from the mounting cavity 404, and a spray hole 407 is provided at the end of the conical cavity 406 away from the mixing cavity 405. The slurry enters the conveying channel 402 in the gun body 401 through the conveying pipe 2, and enters the mixing cavity 405 through the conveying channel 402. The high-pressure airflow enters the air conveying channel 403 through the air conveying pipe 3, and enters the mixing cavity 405 through the air conveying channel 403 and the mounting cavity 404 to mix with the slurry. After the two are mixed, they are sprayed out from the spray hole 407 through the conical cavity 406 for spraying.

[0027] like Figures 3 to 6 As shown, the adjusting assembly 5 includes a piston cylinder 501 fixed inside the mounting cavity 404. An inner cavity 503 is formed at the center of the piston cylinder 501. An inner piston 506 is slidably mounted inside the inner cavity 503. An adjusting rod 508 is fixedly mounted on the side of the inner piston 506 near the conical cavity 406. The adjusting rod 508 is slidably connected to the piston cylinder 501, and its end away from the inner piston 506 extends into the conical cavity 406. A spring 507 is provided on the side of the inner piston 506 away from the adjusting rod 508. An outer cavity 502 is formed outside the inner cavity 503. Both ends of the inner cavity 503 and the outer cavity 502 are connected. An outer piston 504 is slidably mounted inside the outer cavity 502. Four push rods 505 are fixedly mounted on the side of the outer piston 504 away from the conical cavity 406, and all four push rods 505 extend outside the piston cylinder 501. After the slurry enters the conical cavity 406, it will pass through the end of the adjusting rod 508. The slurry enters through the gap between the conical cavity 406 and the nozzle 407, and is finally ejected from the nozzle 407. The gap between the adjusting rod 508 and the conical cavity 406 is the spraying orifice diameter of the slurry. During spraying, the feedback component 6 is pushed by the slurry, which pushes the outer piston 504 along the slurry flow direction through the push rod 505. This forces the gas on the side of the outer cavity 502 away from the push rod 505 into the inner cavity 503, thereby pushing the inner piston 506 to compress the spring 507 and drive the adjusting rod 508 to move. This causes the adjusting rod 508 to move towards the outside of the conical cavity 406, increasing the gap between the end of the adjusting rod 508 and the conical cavity 406, thus adjusting the spraying orifice diameter of the slurry. The greater the viscosity of the slurry, the greater the thrust on the feedback component 6, and the farther the adjusting rod 508 moves, making the gap between the end of the adjusting rod 508 and the conical cavity 406 larger, thereby achieving automatic adjustment of the spraying orifice diameter.

[0028] like Figures 5 to 7 As shown, the feedback component 6 includes a push plate 601 fixed to one end of four push rods 505. A sealing plate 603 is fixedly provided on the top of the push plate 601, and a baffle 602 is fixedly provided on the top of the sealing plate 603. The push plate 601 is annular in shape, and the diameter of its inner hole is larger than the diameter of the air conveying channel 403. The baffle 602 is located inside the material conveying channel 402, has a circular cross-section, a slope at the top, and a semi-circular through hole at the bottom. When the slurry flows in the material conveying channel 402, it will be obstructed by the baffle 602, thereby pushing the baffle 602 to drive the push plate 601 to move along the flow direction of the slurry. The push plate 601 then pushes the push rod 505 to control the adjusting rod 508. When the viscosity of the slurry is higher... The greater the thrust on the baffle 602, the farther the control rod 508 moves, making the gap between the end of the control rod 508 and the conical cavity 406 larger. Ultimately, this achieves automatic adjustment of the spray nozzle diameter according to the viscosity of the slurry, eliminating the need to replace nozzles with different diameters. During this process, the sealing plate 603 separates the material conveying channel 402 from the installation cavity 404, preventing the slurry from flowing into the installation cavity 404. At the same time, the slope set at the top of the baffle 602 can guide the slurry during backwashing, allowing it to pass more smoothly through the semi-circular through hole at the bottom of the baffle 602. The semi-circular through hole at the bottom of the baffle 602 ensures that the water remaining in the material conveying channel 402 can be discharged smoothly at the end of backwashing.

[0029] like Figures 5 to 7 As shown, the control component 7 includes a control rod 701 fixed to one side of the bottom of the push plate 601. A rack 702 is fixedly provided at the end of the control rod 701 away from the push plate 601. A gear 703 meshes with the front of the rack 702. An adjustment switch 704 is fixedly provided at the bottom of the gear 703. The adjustment switch 704 is electrically connected to the sprayer 1. When the push plate 601 moves, it will also drive the rack 702 to move synchronously through the connecting rod. The rack 702 meshes with the gear 703 to drive the adjustment switch 704 to rotate, automatically adjusting the gas output pressure of the sprayer 1.

[0030] The work process is as follows:

[0031] S1: As Figure 1 and Figure 2 As shown, after the sprayer 1 is started, the slurry in the sprayer 1 enters the conveying channel 402 in the gun body 401 through the conveying pipe 2, and then enters the mixing chamber 405 through the conveying channel 402.

[0032] S2: As Figure 1 and Figure 2 As shown, at the same time, the high-pressure gas flow enters the gas delivery channel 403 through the gas delivery pipe 3, and enters the mixing chamber 405 through the gas delivery channel 403 and the mounting cavity 404 to mix with the slurry;

[0033] S3: As Figure 3As shown, after the two are mixed, they enter the spray hole 407 through the gap between the conical cavity 406 and the adjusting rod 508, and are sprayed out from the spray hole 407 for coating.

[0034] S4: As Figure 4 As shown, the slurry is obstructed by the baffle 602 during the process of passing through the conveying channel 402, thereby pushing the baffle 602 to drive the push plate 601 to move along the flow direction of the slurry.

[0035] S5: As Figures 3 to 6 As shown, the push plate 601 pushes the outer piston 504 to move along the flow direction of the slurry through the push rod 505, squeezing the gas on the side of the outer cavity 502 away from the push rod 505 into the inner cavity 503, thereby pushing the inner piston 506 to compress the spring 507 and drive the adjusting rod 508 to move in the opposite direction, so that the adjusting rod 508 moves towards the outside of the conical cavity 406, increasing the gap between the end of the adjusting rod 508 and the conical cavity 406, and adjusting the slurry spraying orifice diameter. When the viscosity of the slurry is greater, the pushing force on the baffle 602 is also greater, thereby making the gap between the end of the adjusting rod 508 and the conical cavity 406 larger.

[0036] S6: As Figures 5 to 7 As shown, when the push plate 601 moves, it will also drive the rack 702 to move synchronously through the connecting rod. The rack 702 meshes with the gear 703 to drive the regulating switch 704 to rotate, so as to synchronously regulate the gas output pressure of the spraying machine 1 to match the viscosity of the slurry.

[0037] The spraying machine 1 and the regulating switch 704 in this application are known technologies in this field, therefore their specific structures and working principles are not described in detail.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
