A spray device to prevent ice blockage

Abstract

A spray device to prevent ice blockage includes an outer shell with an inner shell at its center. The inner shell divides the inner cavity of the outer shell into an independent main channel and a cavity. The top and bottom of the outer shell are respectively equipped with water inlet connectors and spray heads connected to the upper and lower ends of the main channel. The water inlet connectors are connected to one end of a main water inlet pipe. The upper part of the cavity has a water inlet connected to one end of an auxiliary water inlet pipe. The bottom of the cavity has a guide hole. The other ends of the main and auxiliary water inlet pipes are connected to a main water pipe via a three-way solenoid valve. The three-way solenoid valve controls the water flow from the main water pipe to either the main or auxiliary water inlet pipe. An electric heater is installed on the auxiliary water inlet pipe. This device forms a double-layer structure by having an inner shell inside the outer shell. The main channel in the inner shell is for spray water to pass through, and the independent cavity between the inner and outer shells is used to heat and thaw the spray water in the main channel after hot water is injected, preventing the spray water in the main channel from freezing and affecting the spraying effect.

Description

Technical Field

[0001] This utility model relates to a spray device that can prevent ice blockage. Background Technology

[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground through complex biochemical and physicochemical changes. It is widely used, and during coal mining, processing, transportation, and use, it needs to be temporarily stored in coal yards. However, this storage process easily generates large amounts of coal dust, which not only wastes resources but also harms the environment. Current technologies mainly suppress dust by spraying water. However, in low-temperature environments, the spraying device is prone to ice blockage, preventing normal spraying. Therefore, it is necessary to invent a spraying device that can prevent ice blockage. Utility Model Content

[0005] As a further improvement of this utility model, a temperature sensor is provided on the inner side of the main channel.

[0006] As a further improvement of this utility model, a main valve is provided on the main water pipe.

[0007] The beneficial effects of this utility model are as follows:

[0008] The device forms a double-layer structure by having an inner shell inside the outer shell. The main channel in the inner shell is used for spray water to pass through. An independent cavity is formed between the inner shell and the outer shell to heat up and thaw the spray water in the main channel after hot water is injected, so as to prevent the spray water in the main channel from freezing and affecting the spraying effect.

[0012] like Figure 1 As shown, the spray device for preventing ice blockage of this utility model includes an outer shell 1, an inner shell 2 at the center of the outer shell 1, and the inner shell 2 dividing the inner cavity of the outer shell 1 into an independent main channel 4 and a cavity 3. The top and bottom of the outer shell 1 are respectively provided with a water inlet connector 5 and a spray head 6, which are connected to the upper and lower ends of the main channel 4. A temperature sensor 41 is provided inside the main channel 4. The water inlet connector 5 is connected to one end of the main water inlet pipe 7. The upper part of the cavity 3 is provided with a water inlet 31 and connected to one end of the auxiliary water inlet pipe 8. The bottom of the cavity 3 is provided with a guide hole 32. The other ends of the main water inlet pipe 7 and the auxiliary water inlet pipe 8 are connected to the main water pipe 11 through a three-way solenoid valve 10. The main water pipe 11 is provided with a main valve. The three-way solenoid valve 10 controls the water flow in the main water pipe 11 to the main water inlet pipe 7 or the auxiliary water inlet pipe 8. An electric heater is provided on the auxiliary water inlet pipe 8.

[0013] The device forms a double-layer structure by having an inner shell inside the outer shell. The main channel in the inner shell is used for spray water to pass through. An independent cavity is formed between the inner shell and the outer shell to heat up and thaw the spray water in the main channel after hot water is injected, so as to prevent the spray water in the main channel from freezing and affecting the spraying effect.

[0014] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0015] During operation, first open the main valve. Under normal conditions, water in the main water pipe flows along the three-way solenoid valve to the main inlet pipe, and then flows into the main channel along the inlet connector as spray water through the spray heads. When the ambient temperature is too low, causing the spray water in the main channel to freeze and become unable to spray, the three-way solenoid valve switches the water flow direction. The water in the main water pipe flows along the three-way solenoid valve to the auxiliary inlet pipe. The cold water in the auxiliary inlet pipe is heated by the electric heater to form hot water, which flows into the cavity through the inlet. The hot water exchanges heat with the chilled water in the main channel in the cavity, causing the spray water in the main channel to thaw and be able to spray smoothly along the spray heads. The cooling water in the cavity will automatically flow out along the guide hole at the bottom. After thawing, the three-way solenoid valve switches the flow direction again, causing the water in the main water pipe to flow to the main inlet pipe. A temperature sensor is installed in the main channel to set the upper and lower limits of the temperature in the main channel. The switching of the three-way solenoid valve can also be controlled according to the signal of the temperature sensor.

[0016] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
