Description

Technical Field

[0001] This invention relates to the field of spray dust suppression technology, and in particular to a spray dust suppression device that automatically drains water when shut down to prevent low-temperature icing and pipe bursting. Background Technology

[0002] Spraying equipment is a device that transmits liquid through pipes to nozzles and atomizes it using the nozzles. In the present technology, commonly used spraying equipment is often used for dust suppression operations on construction sites.

[0003] In daily spraying operations, spray devices on the market often fail to completely empty the liquid from the pump outlet to the nozzle at the end of spraying. This leads to several disadvantages: First, corrosive liquid remains for an extended period, potentially causing corrosion damage to the pipes and nozzles. Second, in low-temperature environments, such as cold winters, especially in northern regions, the remaining liquid in the pipes can freeze, affecting normal spraying and sometimes causing pipe rupture and nozzle damage.

[0004] Therefore, those skilled in the art have proposed a spray dust suppression device that automatically drains water when the machine stops to prevent low-temperature freezing and pipe bursting, in order to solve the problem that the liquid in the delivery pipeline between the water pump outlet and the nozzle cannot be completely emptied and discharged. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of the present invention is to provide a spray dust suppression device that automatically drains water when shut down to prevent low-temperature icing and pipe bursting.

[0006] The technical solution of the present invention is as follows: a spray dust suppression device for automatic drainage and prevention of low-temperature freezing and pipe bursting when the machine stops, including a liquid storage tank, a tank cover threadedly connected to the top of the liquid storage tank, a liquid inlet on the tank cover, a submersible pump inside the liquid storage tank, the output end of the submersible pump being connected to a drainage structure through a hose, and one end of the drainage structure being connected to a nozzle through a hose.

[0007] The drainage structure includes an inlet pipe, one end of which is fixedly connected to an outlet pipe. A drain pipe is fixedly installed at the connection point between the inlet pipe and the outlet pipe. A fixing rod is fixedly connected between the inner walls of the upper end of the drain pipe. A sealing plate is rotatably connected to the fixing rod. A rotary spring is provided between the fixing rod and the sealing plate. A pressure-boosting plate is provided on the upper surface of the sealing plate. A silicone ring is fitted around the lower end of the drain pipe.

[0008] The sealing plate is located between the inlet pipe and the outlet pipe.

[0009] In a preferred embodiment, both the inlet pipe and the outlet pipe are inclined towards the middle, forming a V-shaped structure.

[0010] In a preferred embodiment, a limiting plate is fixedly provided on the inner wall of the drain pipe on one side of the outlet pipe.

[0011] In a preferred embodiment, the side of the silicone ring facing the drain pipe channel is divided into several silicone petals.

[0012] In a preferred embodiment, when the sealing plate is in a static state, the end of the sealing plate located in the water inlet pipe is lower than the upper end of the drain pipe, and the end of the sealing plate located in the water outlet pipe is higher than the upper end of the drain pipe.

[0013] In a preferred embodiment, the outer surface of the liquid storage tank is provided with a viewing window, and the side of the liquid storage tank is provided with a switch for the submersible pump.

[0014] In a preferred embodiment, a sealing ring is provided at the connection between the water inlet pipe and the water outlet pipe and the hose.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are that, during spraying, the liquid can be transferred to the nozzle through the drainage structure for spraying, and when spraying stops, the liquid in the hose between the nozzle and the submersible pump will converge into the drainage structure due to gravity. Using the action of the rotary spring, a gap is formed between the sealing plate and the drainage pipe, and the residual liquid is discharged from the drainage pipe. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] A spray dust suppression device with automatic drainage and low-temperature freezing and pipe burst prevention when the machine stops includes a liquid storage tank 1, a tank cover 2 threadedly connected to the top of the liquid storage tank 1, a liquid inlet 3 on the tank cover 2, a submersible pump inside the liquid storage tank 1, the output end of the submersible pump is connected to a drainage structure 5 through a hose 4, one end of the drainage structure 5 is connected to a nozzle 6 through a hose 4, liquid is delivered to the drainage structure 5 through the submersible pump, the liquid enters the nozzle 6 after passing through the drainage structure 5, and exits from the nozzle 6 to perform dust suppression operations on the surrounding environment;

[0027] The drainage structure 5 includes an inlet pipe 51, one end of which is fixedly connected to an outlet pipe 52. A drain pipe 53 is fixedly installed at the connection point between the inlet pipe 51 and the outlet pipe 52. A fixing rod 54 is fixedly connected between the upper inner wall of the drain pipe 53. A sealing plate 55 is rotatably connected to the fixing rod 54. A rotary spring 56 is provided between the fixing rod 54 and the sealing plate 55. A pressure plate 57 is provided on the upper surface of the sealing plate 55. A silicone ring 58 is fitted onto the lower end of the drain pipe 53. In a static state, the sealing plate 55 is tilted. Liquid entering from the inlet pipe 51 impacts the pressure plate 57. Due to the water impact, the sealing plate 55 rotates in the direction of water flow until the sealing plate 55 is stably sealed and drains. Pipe 53 allows liquid to be normally delivered to nozzle 6. During rotation, some liquid will be exposed. The silicone ring 58 is used to block the liquid and reduce the leakage speed. When the spraying operation stops, the liquid remaining in the hose between the submersible pump and nozzle 6 is divided into two parts. One part is the hose directly above the submersible pump, which flows back into the pump. The other part is the water remaining in the hose between the top of the hose directly above the submersible pump and nozzle 6, which flows to the drain pipe 53 due to its own gravity. As the water force decreases, the sealing plate 55 returns to its initial state under the action of the rotary spring 56. At this time, the water flow from the inlet pipe 51 and the outlet pipe 52 is discharged from the gap formed by the drain pipe 53 and the sealing plate 55.

[0028] The sealing plate 55 is located between the inlet pipe 51 and the outlet pipe 52.

[0029] Both the inlet pipe 51 and the outlet pipe 52 are inclined towards the middle, forming a V-shaped structure. The special V-shaped structure serves two purposes: first, it increases the weight in the middle of the inlet pipe 51 and the outlet pipe 52, so that the lowest point of the hoses 4 on both sides is located in the middle; second, it makes it easier for the water flow to converge in the drain pipe 53.

[0030] On the inner wall of the drain pipe 53, a limiting plate 531 is fixedly installed on one side of the outlet pipe 52. Due to the large water impact force output by the submersible pump, the sealing plate 55 is prevented from flipping too much, which would prevent the drain pipe 53 from being relatively sealed.

[0031] The side of the silicone ring 58 facing the drain pipe 53 is divided into several silicone flaps 581. The silicone flaps 581 can slow down the speed of liquid falling and make the liquid stay temporarily in the drain pipe 53. Only when the weight of the liquid can open the silicone flaps 581 can it leak out from the inside, reducing the loss of liquid during spraying operations. Secondly, when an external pipeline is needed for liquid recycling, the silicone flaps 581 can be squeezed through the pipeline to achieve fixation and also to relatively seal the recycling pipeline.

[0032] When the sealing plate 55 is in a static state, the end of the sealing plate 55 located on the inlet pipe 51 is lower than the upper end of the drain pipe 53, and the end of the sealing plate 55 located on the outlet pipe 52 is higher than the upper end of the drain pipe 53. The rotary spring 56 is described in the static state. This design allows water to flow out from the gap formed by the drain pipe 53 and the sealing plate 55 when the submersible pump stops operating.

[0033] The outer surface of the liquid storage tank 1 is provided with a viewing window, and the side of the liquid storage tank 1 is provided with a switch for the submersible pump. The remaining liquid level inside the liquid storage tank 1 can be observed through the viewing window, and the switch for the submersible pump on the side can be turned on and off at any time to control the spraying operation.

[0034] Sealing rings are provided at the connection points of the inlet pipe 51 and outlet pipe 52 with the hose 4 to facilitate the connection of the hose 4 and to seal the incoming and outgoing liquids, preventing leakage.

[0035] Working principle:

[0036] As shown in the figure, during use, liquid is poured into the storage tank 1. The liquid level inside the storage tank 1 is observed through the viewing window. After the liquid input is complete, the tank cover 2 is closed, and the submersible pump is turned on to start the spraying operation. The liquid will be transmitted from the output end of the submersible pump to the drainage structure 5, entering from one end of the inlet pipe 51. The water flow provided by the submersible pump has an impact force, and the impact of the water flow will first impact the pressure plate 57, causing the pressure plate 57 to drive the sealing plate 55 to rotate around the fixed rod 54. During the rotation, the sealing plate 55 will be restricted by the limiting plate 531, causing the sealing plate 55 to contact the limiting plate 531, allowing the water flow to pass smoothly through the inlet pipe 51 and the outlet pipe 52, and be delivered to the nozzle. In step 6, dust suppression operations are carried out on the surrounding environment. After the spraying operation is completed, the submersible pump is turned off by controlling the switch of the submersible pump. At this time, the liquid inside the hose 4 directly above the submersible pump will flow back into the liquid storage tank 1. Due to the gravity of the drainage structure 5 itself, the hose 4 droops down and the drainage structure 5 is at the lowest end. At this time, the liquid remaining inside the hose 4 between the top of the hose 4 and the nozzle 6 will flow back into the drain pipe 53. Due to the lack of support from the submersible pump, the impact force of the water flow is reduced. The sealing plate 55 is restored to its initial state by the action of the rotation spring 56. At this time, the water flow from the inlet pipe 51 and the outlet pipe 52 is discharged from the gap formed by the drain pipe 53 and the sealing plate 55.

[0037] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
