Description

Technical Field

[0001] The utility model relates to the technical field of precast brick treatment, in particular to a spraying device for precast bricks. Background Technique

[0002] Concrete precast bricks use concrete as raw materials. Concrete is one of the most important building materials nowadays. It is prepared by mixing cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added as necessary in a certain proportion, and is an artificial stone formed by uniform stirring, dense molding, and curing and hardening. Precast bricks are pre-produced bricks that can be directly used during installation;

[0003] When precast bricks are produced, it is necessary to spray the surface of the precast bricks to cure the precast bricks, improve the overall quality of the precast bricks, and prevent cracks.

[0004] Most of the existing devices spray precast bricks by top spraying, but the spraying effect is poor. The sprayed water cannot penetrate to the bottom, and it is easy to have uneven spraying. Moreover, when spraying, excess residues will also fall off, which is not convenient for cleaning.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a spraying device for precast bricks is proposed, in order to achieve a more practical and valuable purpose. Content of the Utility Model

[0006] The purpose of the utility model is to provide a spraying device for precast bricks to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A spraying device for precast bricks, including a workbench and a spray pipe. A protective plate is installed on the outer side of the top of the workbench, and lifting auxiliary side rails are symmetrically installed inside the protective plate. A spray box is connected inside the lifting auxiliary side rails. Spray grooves are opened on the inner wall of the spray box, and spray pipes are horizontally arranged inside the spray grooves. The spray pipes and the spray grooves are matched in size. Spray holes are arranged in rows on the inner side of the spray pipes, and the aperture sizes of the spray holes decrease in sequence as the horizontal height decreases. Water inlet pipes are connected to both sides of the top of each group of spray pipes. A lifting rod is arranged at the connection between the top of the protective plate and the outside of the spray box;

[0008] A collection box is connected to the bottom of the workbench, and sinking grooves are opened on both sides of the top of the collection box. A filter screen plate is slidably installed inside the sinking grooves;

[0009] A spray table is arranged in the middle of the workbench.

[0010] Further, the spray pipes are arranged in a row along the inner wall of the spray box, and there are three groups of spray pipes.

[0011] Further, the aperture diameters of the spray holes at the vertical ends of the spray pipes decrease successively as the horizontal height decreases, and the aperture diameters of the spray holes at the horizontal ends of the spray pipes are the same.

[0012] Further, the bottom end of the inner cavity of the collection box is inclined.

[0013] Further, the protection plate forms an up-and-down fitting sliding structure between the lifting auxiliary side rails and the spray box, and the protection plate forms a driving lifting structure between the lifting rod and the spray box.

[0014] Further, the spray box and the spray table are matched in terms of the orifice sizes through the spray groove.

[0015] The utility model provides a spray device for precast bricks, which has the following beneficial effects:

[0016] 1. In the utility model, by adopting the way of upper and lower sleeving and using the slide rail and slider and the lifting rod, it is ensured that the spray box can accurately cover the outside of the precast brick to be sprayed, covering the whole precast brick, which is convenient for the spray box to completely process the precast brick;

[0017] The outer spray box can also reduce the splashing during spraying and ensure the stability during the spraying process.

[0018] 2. In the utility model, common spray pipes are used as the spray parts for the precast bricks, which reduces the spray cost and prolongs the service life. Spray holes are opened on the inner side of the spray pipes, and the curing water is sprayed out through the spray holes to spray the precast bricks;

[0019] The aperture diameters of the spray pipes on the side ends, that is, the orifice sizes, gradually decrease as the horizontal height decreases. By reducing the aperture diameters, the water pressure of the sprayed water can be increased, avoiding the situation that the water droops under the action of gravity during spraying and affecting the spraying effect.

[0020] 3. In the utility model, sinking grooves are opened on both sides of the top of the collection box to collect the excess water during spraying, and through the filter mesh plate slidably embedded on the inner side, the residues falling during spraying are separated and recycled, avoiding the residues from affecting the recycling of the excess water.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-3 , the present utility model provides a technical solution: a spraying device for precast bricks, including a workbench 1 and a spraying pipe 8. A protective plate 2 is installed on the outer side of the top of the workbench 1, and lifting auxiliary side rails 7 are symmetrically installed on the inner side of the protective plate 2. And a spraying box 6 is connected to the inner side of the lifting auxiliary side rail 7. A spraying groove 9 is provided on the inner wall of the spraying box 6, and spraying pipes 8 are horizontally arranged inside the spraying groove 9. And the sizes of the spraying pipes 8 and the spraying groove 9 are matched with each other. Spraying holes 801 are arranged in a row on the inner side of the spraying pipe 8, and the aperture sizes of the spraying holes 801 decrease in sequence as the horizontal height decreases. Water inlet pipes 802 are connected to both sides of the top of each group of spraying pipes 8. A lifting rod 10 is provided at the connection between the top of the protective plate 2 and the outer side of the spraying box 6;

[0028] The bottom of the workbench 1 is connected to a collection box 4, and sinking grooves 3 are provided on both sides of the top of the collection box 4. And a filter screen plate 11 is slidably installed inside the sinking grooves 3;

[0029] A spraying table 5 is provided in the middle of the workbench 1;

[0030] The spraying pipes 8 are arranged in a row along the inner wall of the spraying box 6, and there are three groups of spraying pipes 8;

[0031] The aperture sizes of the spraying holes 801 at the vertical ends of the spraying pipes 8 decrease in sequence as the horizontal height decreases, and the aperture sizes of the spraying holes 801 at the horizontal ends of the spraying pipes 8 are the same;

[0032] The bottom end of the inner cavity of the collection box 4 is inclined.

[0033] The protective plate 2 forms an up-and-down fitting sliding structure between the lifting auxiliary side rail 7 and the spray box 6, and the protective plate 2 forms a driving lifting structure between the lifting rod 10 and the spray box 6.

[0034] The spray box 6 and the spray table 5 are matched in diameter through the spray groove 9.

[0035] In an up-and-down sleeving manner, by using the slide rail and slider and the lifting rod, it is ensured that the spray box 6 can accurately cover the outside of the precast brick to be sprayed, covering the whole precast brick, which is convenient for the spray box 6 to completely process the precast brick.

[0036] The outer spray box 6 can also reduce the splashing during spraying and ensure the stability during the spraying process.

[0037] A common spray pipe 8 is used as the spraying part for the precast brick, which reduces the spraying cost and extends the service life. Spray holes 801 are opened on the inner side of the spray pipe 8, and the curing water is sprayed through the spray holes 801 to spray the precast brick.

[0038] The aperture on the side end of the spray pipe 8 gradually shrinks as the horizontal height decreases. By shrinking the aperture, the water pressure of the sprayed water can be increased, avoiding the drooping of water under the action of gravity during spraying and affecting the spraying effect.

[0039] Sink grooves 3 are opened on both sides of the top of the collection box 4 to collect the excess water during spraying, and the filter mesh plate 11 embedded in the inner side by sliding is used to block and recycle the residues falling during spraying, avoiding the residues from affecting the recycling of the excess water.

[0040] Working principle: For such a spraying device for precast bricks, first, the precast bricks to be cured are transported to the upper end of the spray table 5 through the backing plate. Then, the lifting rods 10 symmetrically distributed on the outside drive the spray box 6 at the top to descend, so that the spray box 6 stably covers the precast bricks at the bottom with the assistance of the lifting auxiliary side rail 7. Then, the pump of the curing water is started, so that the curing water is transported from the top water inlet pipe 802, enters the spray pipe 8, and is sprayed out from the inner spray holes 801. The precast bricks inside are sprayed by using the spray holes 801 with different sizes. The splashed water during spraying will be blocked by the inner wall of the spray box 6 and slide down along the inner wall of the spray box 6. The excess sprayed water will be recycled through the sink grooves 3, and the sprayed water will pass through the filter mesh plate 11 during recycling to block and recycle the residues falling during spraying, completing the spraying operation.
