Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to an air pollution prevention spraying device. Background Technique

[0002] With the development of the economy, people's demand for urban construction increases. A large amount of dust will be generated during the construction of buildings and industrial production. A large amount of dust is mixed in the air, which has a direct harm to people's health. In daily dust removal, the use of water mist spraying devices is mainly used.

[0003] At present, the spraying device is directly connected to the tap water pipe. However, the tap water contains more impurities. After long-term use, the spray head will be blocked, resulting in the failure of spraying and seriously affecting the dust reduction effect. Therefore, we propose an air pollution prevention spraying device that can filter the water source and prevent blockage. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an air pollution prevention spraying device to solve the technical problems mentioned in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an air pollution prevention spraying device, including a surrounding plate, the top of the surrounding plate is provided with spray heads, and there are multiple groups of spray heads distributed at intervals. A cavity is opened inside the surrounding plate, and a water inlet pipe communicating with the external water source is arranged in the cavity. Above the water inlet pipe, a water supply pipe communicating with the spray heads is arranged. A filter pipe for filtering the water source is installed between the water inlet pipe and the water supply pipe.

[0006] By adopting the above technical scheme, the water source supplied to the spray heads can be filtered, thereby preventing the spray heads from being blocked and ensuring the long-term stable operation of the spray heads.

[0007] The utility model is further set as follows: a filter screen is installed in the filter pipe, and the filter screen is detachably connected to the filter pipe by bolts.

[0008] By adopting the above technical scheme, the effect of filtering the water source is achieved.

[0009] The utility model is further set as follows: the filter pipe is composed of two parts, and the filter pipe includes a first rotating part and a second rotating part. The first rotating part and the second rotating part are vertically limited, horizontally limited and axially rotatably connected.

[0010] By adopting the above technical scheme, the effect of assisting the disassembly and installation of the filter pipe is achieved.

[0011] The present utility model is further configured such that a threaded wall is provided on the inner wall of the top of the first rotating part, and a threaded wall is also provided on the inner wall of the bottom of the second rotating part.

[0012] By adopting the above technical solution, the effect of assisting in the disassembly and installation of the filter pipe is achieved.

[0013] The present utility model is further configured such that a first threaded plate adapted to the threaded wall of the first rotating part is fixed to the bottom end of the water supply pipe, and a second threaded plate adapted to the threaded wall of the second rotating part is fixed to the top end of the water inlet pipe.

[0014] By adopting the above technical solution, the effect of disassembling and installing the filter pipe is achieved.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] 1. By providing a filter pipe and a filter screen, first, when the external water source supply is turned on, the external water source will enter the water supply pipe through the water inlet pipe, thereby providing water source for the spray head. The spray head realizes the spraying effect by sucking the water in the water supply pipe, so as to achieve the purpose of dust reduction. Further, during the process of water flowing through the water inlet pipe into the water supply pipe, the filter pipe can filter the passing water flow. Specifically, the water in the water inlet pipe will enter the filter pipe. Under the action of the filter screen in the filter pipe, the impurities in the water flow will be intercepted, and then the purified water flow will enter the water supply pipe to provide water source for the spray head;

[0017] 2. By providing a threaded plate, a rotating part and a threaded wall, in order to ensure the functionality of the filter screen, a quick disassembly structure of the filter screen is added in this solution. Specifically, by rotating the first rotating part, the first threaded plate is disconnected from the first rotating part. Further, by rotating the second rotating part again, the second threaded plate is disconnected from the second rotating part. At this time, the filter pipe will be disconnected from both the water inlet pipe and the water supply pipe, so as to realize the quick disassembly of the filter pipe. Subsequently, by removing the filter screen in the filter pipe with bolts, the quick disassembly of the filter screen can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] An air pollution prevention spray device, as Figures 1 - 4 shown, includes an enclosing plate 1. A spray head 2 is installed at the top of the enclosing plate 1, and there are multiple groups of spray heads 2 distributed at intervals. A cavity is formed inside the enclosing plate 1, and a water inlet pipe 3 communicating with an external water source is arranged in the cavity. Above the water inlet pipe 3, a water supply pipe 4 communicating with the spray head 2 is arranged, and a filter pipe 5 for filtering the water source is installed between the water inlet pipe 3 and the water supply pipe 4;

[0026] Furthermore, in this embodiment, a filter screen 6 is installed in the filter pipe 5, and the filter screen 6 is detachably connected to the filter pipe 5 by bolts.

[0027] Please refer to Figure 4 , the filter pipe 5 is composed of two parts, and the filter pipe 5 includes a first rotating part 7 and a second rotating part 8. The first rotating part 7 and the second rotating part 8 are vertically limited, horizontally limited and axially rotatably connected to realize the disassembly and installation of the auxiliary filter pipe 5.

[0028] Please refer to Figure 4 , the inner wall of the top of the first rotating part 7 is provided with a threaded wall, and the inner wall of the bottom of the second rotating part 8 is also provided with a threaded wall. A first threaded plate 9 adapted to the threaded wall of the first rotating part 7 is fixed at the bottom end of the water supply pipe 4, and a second threaded plate 10 adapted to the threaded wall of the second rotating part 8 is fixed at the top end of the water inlet pipe 3 to realize the disassembly and installation of the filter pipe 5.

[0029] The working principle of the present invention is as follows: First, turn on the external water source supply. At this time, the external water source will enter the water supply pipe 4 through the water inlet pipe 3, so as to provide water source for the spray head 2. The spray head 2 realizes the spray effect by sucking the water in the water supply pipe 4, so as to achieve the purpose of dust reduction;

[0030] Further, during the process that water flows through the water inlet pipe 3 and enters the water supply pipe 4, the filter pipe 5 can filter the passing water flow. Specifically, the water in the water inlet pipe 3 will enter the filter pipe 5. Under the action of the filter screen 6 in the filter pipe 5, the impurities in the water flow will be intercepted. Then, the purified water flow will enter the water supply pipe 4 to provide water source for the spray head 2.

[0031] In addition, in order to ensure the functionality of the filter screen 6, a quick disassembly structure for the filter screen 6 is additionally provided in this solution. Specifically, by rotating the first rotating part 7, the first threaded plate 9 is disconnected from the first rotating part 7. Further, by rotating the second rotating part 8 again, the second threaded plate 10 is disconnected from the second rotating part 8. At this time, the filter pipe 5 will be disconnected from both the water inlet pipe 3 and the water supply pipe 4, so as to realize the quick disassembly of the filter pipe 5. Subsequently, the filter screen 6 in the filter pipe 5 can be quickly disassembled by removing the bolts of the filter screen 6.
