Description

Technical Field

[0001] This utility model relates to the technical field of equipment for preparing monoammonium phosphate, specifically a slurry spraying device. Background Technology

[0002] Monoammonium phosphate (MAP) is an important raw material widely used in chemical production, mainly as a fertilizer and food additive. It has high water solubility and can provide plants with the two main nutrients, nitrogen and phosphorus. The manufacturing process of MAP involves multiple chemical reactions and physical operations. Therefore, in-depth research on its manufacturing methods can help improve production efficiency, reduce costs, and enhance product quality.

[0003] In the existing preparation process of monoammonium phosphate, the manufacturing process requires injecting slurry into a preparation tank, and then adjusting its solubility by adding aqueous solution. Since the slurry is mostly stored in packaging tanks before feeding, in order to avoid workers lifting the packaging tanks high to pour the slurry, the existing technology uses a pump to extract the slurry and then injects it into the preparation tank by spraying. However, during the spraying process, the operator usually needs to hold the spray gun continuously to spray, which increases the burden on the workers. Therefore, a slurry spraying device is proposed. Utility Model Content

[0004] This invention provides a slurry injection device to solve the technical problem that in the preparation of monoammonium phosphate, when slurry is injected by spraying with a spray gun, workers need to hold the spray gun for a long time, which is a heavy burden on the workers.

[0005] The technical solution of this utility model is as follows: A slurry spraying device for spraying material onto a preparation tank for preparing monoammonium phosphate, comprising:

[0006] The fixed structure includes a U-shaped strip with two sets of waist holes. A positioning plate is movably arranged between the front and rear side walls of the U-shaped strip. A protruding post is fixed on both the front and rear sides of the positioning plate, passing through the corresponding waist hole. A nut is threadedly connected to the outer side of the protruding post.

[0007] The platform is fixed to the side of the positioning plate away from the preparation tank;

[0008] The spraying structure includes a material pump and a spray gun, wherein the material pump is fixed to the platform by bolts, a connecting pipe is installed between the outlet of the material pump and the spray gun, and a material pumping pipe is installed at the inlet of the material pump.

[0009] The gun clip structure, which is set on the positioning plate, is used to clamp the spray gun.

[0010] Furthermore, a support platform is integrally connected to the positioning plate, the support platform has an inclined surface, and the gun clip structure is disposed on the inclined surface of the support platform.

[0011] Furthermore, the gun clip structure includes a gun base and a gun cover, wherein the gun base and the gun cover each have a groove on their opposite sides, forming a placement area between the gun base and the gun cover. The spray gun is located in this placement area, and the gun base is set on the inclined surface of the support platform. Several mounting holes are opened on both the gun cover and the gun base. Threaded posts are set in the mounting holes, and two sets of nuts are threaded to the outside of any set of threaded posts.

[0012] Furthermore, the spraying structure is movably mounted on the inclined surface of the support platform, and the spray nozzle of the spray gun is positioned facing the inlet of the preparation tank.

[0013] Furthermore, it also includes a telescopic component, which is fixed to the outside of the support platform by bolts. A groove is provided on the inclined surface of the support platform, and a slider installed on the telescopic end of the telescopic component is slidably connected in the groove. The gun seat is fixed on this slider, allowing the spraying structure to be movably set on the inclined surface of the support platform.

[0014] Furthermore, the telescopic component is either a cylinder or an electric push rod.

[0015] Furthermore, the number of U-shaped strips is no less than two sets, used to reinforce the slurry spraying device to the outside of the preparation tank.

[0016] Furthermore, the number of U-shaped strips is two sets, and the two sets of U-shaped strips are distributed vertically.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1 and Figure 2 As shown, this embodiment of a slurry spraying device is used to spray material onto a preparation tank 1 for preparing monoammonium phosphate. In use, it is detachably installed on the outside of the preparation tank 1. The slurry spraying device includes a fixing structure 2, a platform 3, a spraying structure 4, and a gun clamp structure 5. The slurry spraying device is detachably installed on the outside of the preparation tank 1 via the fixing structure 2. The spraying structure 4 includes a pump 41, a spray gun 42, a connecting pipe 43, and a suction pipe 44. The pump 41 in the spraying structure 4 is fixed to the platform 3 by bolts, i.e., the platform 3 provides support space for the pump 41. The spray gun 42 is fixed by the gun clamp structure 5. The connecting pipe 43 is fixedly installed between the outlet of the pump 41 and the spray gun 42, and the suction pipe 44 is fixedly installed at the inlet of the pump 41.

[0027] It should be noted that the connecting pipe 43 and the extraction pipe 44 in the above-mentioned spray structure 4 are both flexible hoses to meet the requirements of position adjustment.

[0028] With this design, the worker aligns the end of the extraction pipe 44 furthest from the extraction pump 41 with the corresponding packaging barrel containing the slurry, starts the extraction pump 41, and guides the slurry through the extraction pipe 44 and the connecting pipe 43, allowing the slurry to flow out from the spray gun 42 and into the preparation tank 1. Because the fixed structure 2 is used to detachably fix the slurry spraying device to the outside of the preparation tank 1, and makes reasonable use of the stable support of the preparation tank 1 itself, the worker does not need to hold the spray gun 42 continuously. In this way, the work of spraying slurry is more stable, and it can free the worker's hands and reduce the burden on the worker.

[0029] To facilitate understanding of the positions and structures of the aforementioned fixing structure 2, platform 3, and gun clip structure 5, the following description is provided. As shown in 1-4, the fixing structure 2 includes a U-shaped strip 21, which has two sets of waist holes 22. The two sets of waist holes 22 are located on the front and rear sides of the U-shaped strip 21, respectively, and the two sets of waist holes 22 pass through the front and rear side walls of the U-shaped strip 21, providing a through space. A positioning plate 23 is movably arranged between the front and rear side walls of the U-shaped strip 21. The front and rear sides of the positioning plate 23 are fixed with protruding posts 24 that pass through the corresponding waist holes 22. Nuts 25 are threadedly connected to the outer side of the protruding posts 24.

[0030] It should be noted that with this design, the side of the positioning plate 23 away from the preparation tank 1 has sufficient space for support. Therefore, the platform 3 is fixed to the side of the positioning plate 23 away from the preparation tank 1, so that the platform 3 can provide sufficient support space for the pump 41.

[0031] It should also be noted that the gun clip structure 5 is mounted on the positioning plate 23 at this time, and is used to clamp the spray gun 42. Further explanation of the gun clip structure 5 is as follows... Figure 1-3 As shown, a support platform 26 is integrally connected to the positioning plate 23. The support platform 26 has an inclined surface, and the gun clip structure 5 is set on the inclined surface of the support platform 26, so that the gun clip structure 5 can be aligned with the inlet of the preparation tank 1.

[0032] like Figure 1-3 As shown, the gun clip structure 5 in this embodiment includes a gun base 51 and a gun cover 52. Both the gun base 51 and the gun cover 52 have grooves on opposite sides, forming a placement area between the gun base 51 and the gun cover 52. The spray gun 42 is located in this placement area, and the gun base 51 is fixedly installed on the inclined surface of the support platform 26. Several mounting holes are provided on both the gun cover 52 and the gun base 51. Threaded posts 53 are provided in the mounting holes, and two sets of nuts are threaded to the outside of any set of threaded posts 53.

[0033] With this design, the distance between the gun cover 52 and the gun base 51 is adjusted by placing the spray gun 42 in the placement area and using the threaded post 53 and nut, thereby locking and fixing the spray gun 42.

[0034] Considering that the preparation tank 1 sometimes needs to be covered, to ensure that the spray gun 42 in the spray structure 4 does not interfere with the subsequent sealing of the cover, such as Figure 1-3 As shown, the spray structure 4 is movably mounted on the inclined surface of the support platform 26, and the spray nozzle of the spray gun 42 is positioned facing the inlet of the preparation tank 1.

[0035] In one embodiment of this design, the slurry spraying device further includes a telescopic component 6, which is fixed to the outside of the support platform 26 by bolts. A groove is provided on the inclined surface of the support platform 26, and a slider 7 installed on the telescopic end of the telescopic component 6 is slidably connected in the groove. The gun seat 51 is fixed on the slider 7, so that the spraying structure 4 can be movably set on the inclined surface of the support platform 26.

[0036] It should be noted that the telescopic component 6 is either a cylinder or an electric push rod. Cylinders and electric push rods are existing technologies and mainly serve to adjust the telescopic movement, which will not be elaborated on here.

[0037] In use, the position of the slider 7 is adjusted by utilizing the telescopic characteristics of the telescopic component 6 to control the distance between the space spray gun 42 and the preparation tank 1. During spraying, the outlet of the spray gun 42 is brought close to the preparation tank 1 to facilitate material loading. After loading, the spray gun 42 is moved away from the preparation tank 1 to avoid interference when the preparation tank 1 is subsequently covered.

[0038] To ensure the stable mounting of the slurry spraying device on the outside of the preparation tank 1, in one embodiment, such as... Figure 1 and 2 As shown, there are no fewer than two sets of U-shaped strips 21. With this design, the number of fixing structures 2 is the same as the number of U-shaped strips 21. By using multiple sets of fixing structures 2, the slurry spraying device can be strengthened and fixed to the outside of the preparation tank 1.

[0039] In the preferred embodiment of the U-shaped strip 21, there are two sets of U-shaped strips 21, which are distributed vertically.

[0040] In this design, the operation of the fixing structure 2 is explained as follows: by placing the U-shaped strip 21 on the outside of the preparation tank 1, and then adjusting the position of the positioning plate 23, when the positioning plate 23 and the U-shaped strip 21 form a clamping force on the outside of the preparation tank 1, rotate the nut 25 until the nut 25 is tightly against the U-shaped strip 21. In this way, the positioning plate 23 is limited, so that the slurry spraying device can be fixed to the outside of the preparation tank 1 through this fixing structure 2.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
