[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] As shown in the figure, this embodiment provides a dry mist generator pipeline backflush device, including a dry mist generator body 1, a liquid outlet pipe 2, and a delivery pipe 3. The liquid outlet pipe 2 is fixedly installed at one end of the dry mist generator body 1, and an annular groove 21 is provided at one end of the liquid outlet pipe 2 away from the dry mist generator body 1, and an annular groove 21 of the same structure is also provided at one end of the delivery pipe 3. Figure 2 and Figure 3 shown.

[0027] A connecting pipe 5 is installed between the liquid outlet pipe 2 and the delivery pipe 3, wherein the outer diameters of both ends of the connecting pipe 5 are smaller than the outer diameters of the liquid outlet pipe 2 and the delivery pipe 3, but are equal to the outer diameter of the annular groove 21. Therefore, both ends of the connecting pipe 5 can be inserted into the inner part of the annular groove 21, so that the liquid outlet pipe 2, the connecting pipe 5, and the delivery pipe 3 are combined into a whole, and the liquid outlet pipe 2 and the delivery pipe 3 can be connected under the action of the connecting pipe 5. Figure 1 shown.

[0028] The connecting pipe 5 has external threads on its two ends near the edge, and the liquid outlet pipe 2 and the delivery pipe 3 have external threads on their outer circumferential surfaces at one end where the connecting pipe 5 is attached. Figure 2 , Figure 3 and Figure 4 shown.

[0029] A threaded sleeve 4 is rotatably mounted on the outer circumferential surface of the connection position of the liquid outlet pipe 2 and the connecting pipe 5. After one end of the connecting pipe 5 is installed in the annular groove 21, the outer diameter of the circumferential surface of the connecting pipe 5 with the external thread is the same as the outer diameter of the liquid outlet pipe 2. Under the action of the threaded sleeve 4, the place where the liquid outlet pipe 2 and the connecting pipe 5 are in contact can be sealed to avoid air leakage or later leakage at the connection. The place where the delivery pipe 3 and the connecting pipe 5 are in contact is the same as the above situation. Figure 1 shown.

[0030] Bandages are wrapped around the outer threaded circumferences of the liquid outlet pipe 2 and the delivery pipe 3 to further enhance the sealing effect of the connection. Secondly, an annular waterproof gasket is arranged inside the annular groove 21 where the connecting pipe 5 is installed to prevent leakage, etc. (the waterproof gasket can be installed according to the actual situation on site in specific use).

[0031] A convex chute 9 is fixedly installed inside the connecting tube 5 near one end of the liquid outlet pipe 2, and a plurality of hinges 8 are slidably installed on the convex chute 9, wherein the hinge 8 is a semicircular structure, and two hinges 8 are slidably installed on the convex chute 9, and the two hinges 8 can be combined into a disc-shaped structure, and its diameter is consistent with the inner diameter of the connecting tube 5, such as Figure 4 The edges of the two hinges 8 that are in contact are connected together by the hinges 8 being rotatably mounted.

[0032] A groove is provided at the arc vertex of the hinge 8, a cylinder is fixedly installed inside the groove, a connecting piece is rotatably installed on the circumference of the cylinder, and the other end of the connecting piece rotates on the circumference of the slide rod 81, and the slide rod 81 is slidably installed inside the convex slide groove 9, such as Figure 5 shown.

[0033] A groove is also provided at the center of the straight edge of the hinge 8, a cylinder is fixedly installed inside the groove, a connecting plate is rotatably installed on the circumferential surface of the cylinder, and the other end of the connecting plate is fixedly installed on one end of the rack 71, such as Figure 5 As shown. Driven by the rack 71, the two hinges 8 in the vertical state can gradually change their state. In addition, under the action of the rack 71, the two hinges 8 can be controlled to block one end of the connecting pipe 5, so that the connecting pipe 5 and the conveying pipe 3 are in a disconnected state. Figure 4 shown.

[0034] Two identical cylinders are fixedly installed on the inner wall of the connecting pipe 5, and a U-shaped slide groove 7 is fixedly installed on the end of the cylinder away from the inner wall, and the rack 71 is slidably installed inside the U-shaped slide groove 7. The U-shaped slide groove 7 can keep the rack 71 in a horizontal state to prevent one end of the rack 71 from falling off. Figure 5 shown.

[0035] An adjusting rod 6 is rotatably installed on the circumferential surface of the connecting tube 5. One end of the adjusting rod 6 extends to the inside of the connecting tube 5 and a gear 61 is installed on the circumferential surface. The gear 61 is meshed with the rack 71. When the adjusting rod 6 is rotated, the gear 61 can rotate synchronously, so that the gear 61 drives the rack 71 to slide horizontally and linearly, and then the rack 71 drives the hinge 8 to move, so that the hinge 8 can change from a state of blocking the connecting tube 5 to a state of connection, or to the opposite state.

[0036] An air compressor 10 is connected to the circumferential surface of the connecting pipe 5. The air compressor 10 and the connecting pipe 5 are connected through a pipeline. The air compressor 10 can compress the air and release it inside the connecting pipe 5, and then enter the inside of the delivery pipe 3 to clean the dirt and water stains remaining inside the delivery pipe 3. Figure 4 When cleaning, the adjusting rod 6 needs to be rotated to drive the rack 71 to pull the hinge 8 to block the end close to the liquid outlet pipe 2 to prevent the subsequent compressed air from entering the interior of the liquid outlet pipe 2. Figure 4 shown.

[0037] The air compressor 10 compresses the air in the atmosphere to make the pressure inside the air compressor 10 reach the set pressure value (0.4-0.7Mpa, which can be set according to actual use requirements), and then opens the valve between the air compressor 10 and the connecting pipe 5 to allow the compressed air to flow into the connecting pipe 5. Figure 1 shown.

[0038] After the air enters the interior of the connecting pipe 5, since the connecting pipe 5 is connected with the conveying pipe 3, the air will gradually enter the interior of the conveying pipe 3. Figure 1 As shown. Under the action of pressure, the water stains adsorbed on the inner wall of the delivery pipe 3 will be driven by the pressure to flow toward the spray port (the water stains have fluidity, such as the water stains will flow under the blowing of wind), and then flow out through the spray head.

[0039] The water stains that do not flow out through the spray head will flow to the farthest end of the delivery pipe 3 under the action of pressure, and then flow out through the spray head at the edge of the delivery pipe 3 under the action of pressure.

[0040] When the air compressor 10 is operating, the pressure generated is too high. After the valve is opened, the flow rate of the gas increases significantly, which will generate a shock wave with a large impact force (the air compressor 10 can be opened repeatedly to make the gas flow suddenly and impact the dirt inside the delivery pipe 3), thereby knocking off the dirt on the inner wall of the delivery pipe 3, and then the flow rate of the gas is reduced, so that the dirt is affected by gravity and stays on the inner wall of the delivery pipe 3. However, under the action of the air compressor 10, the dirt inside the delivery pipe 3 can be removed, but when cleaning, only the circumferential surface of the pipe wall can be backblown, and the corners and dead corners in the delivery pipe 3 cannot be cleaned. Therefore, when the air compressor 10 is operating, it needs to be adjusted according to the specific situation.

[0041] When dirt falls off, the hinge 8 is opened to flush the inside of the delivery pipe 3 , and smaller dirt will flow out with the liquid, while larger dirt will remain in the inside of the delivery pipe 3 .

[0042] After flushing with liquid several times, use the air compressor 10 to blow the remaining dirt to the farthest end of the delivery pipe 3, manually unscrew the bolt head for manual cleaning, and after cleaning, tighten the bolt head and repeat the above steps until the inside of the delivery pipe 3 meets the cleaning requirements.

[0043] The working principle is as follows: after installing the dry fogger body 1, manually place a waterproof gasket inside the annular groove 21, and then install one end of the connecting pipe 5 inside the annular groove 21. After plugging in, rotate the threaded sleeve 4 to fix the liquid outlet pipe 2 and the connecting pipe 5.

[0044] Then, the delivery pipe 3 and the connecting pipe 5 are fixedly connected according to the same steps.

[0045] The adjusting lever 6 is rotated to adjust the state of the hinge 8 so that the water source inside the dry mist generator body 1 can enter the inside of the conveying pipe 3, thereby performing dust suppression operations.

[0046] Secondly, the inside of the delivery pipe 3 is impacted multiple times under the action of the air compressor 10 to clean the dirt inside the delivery pipe 3, and then the inside of the delivery pipe 3 is ensured to be clean by flushing with liquid.

[0047] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be determined by the attached claims and their equivalents.
