Description

Technical Field

[0001] This utility model relates to the field of spray cleaning technology, specifically to a leak-proof high-pressure spray device. Background Technology

[0002] In the spray cleaning process, the items to be cleaned are typically conveyed by a conveyor and pass through a spray device, where water is sprayed to rinse the surface of the items. Furthermore, for items with stubborn stains, high-pressure rinsing is usually required, thus high-pressure water flows through the spray device.

[0003] In the cleaning process, since the items to be cleaned are distributed at intervals on the conveyor, in order to save water, the spraying device only turns on when there are items to be cleaned and stops spraying when there are no items to be cleaned. A quick on / off response is required, and solenoid valves are often used to control the opening and closing of the spraying.

[0004] However, when high-pressure water flows into a switch that is rapidly opened and closed, water hammer can easily occur, which can cause the connections in the water pipeline to loosen and lead to leaks. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model proposes a leak-proof high-pressure spray device.

[0006] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

The upper end of the water inlet pipe extends upward out of the spray chamber and is connected to a solenoid valve. The lower end of the water inlet pipe extends into the spray chamber and is connected to several spray heads. The several spray heads are evenly distributed along the width direction of the conveyor belt.

[0010] An infrared sensor is located at the inlet and faces the upper end of the conveyor belt;

[0011] A water hammer elimination assembly is connected to the water inlet pipe and located away from the solenoid valve in the spray chamber.

[0012] In a preferred embodiment, the water hammer elimination assembly includes a tank with an inner cavity inside. The length direction of the inner cavity is perpendicular to the water inlet pipe. One end of the inner cavity is connected to the water inlet pipe. A sliding piston is fitted inside the inner cavity. The tank has an air inlet that is connected to the other end of the inner cavity. The air inlet is equipped with a valve. A pressure gauge is mounted on the tank, and the probe of the pressure gauge is located at the same end of the inner cavity connected to the air inlet.

[0013] In a preferred embodiment, a liquid level sensor is provided on the inner wall of the wastewater tank, and the liquid level sensor is positioned near the upper end of the wastewater tank.

[0014] In a preferred embodiment, the spray assembly is provided in multiple sets, and the multiple sets of spray assemblies are distributed sequentially at intervals along the conveying direction of the conveyor belt.

[0016] Compared with existing technologies, the beneficial effects are:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] A leak-proof high-pressure spray device includes: a spray chamber 1, a spray assembly, an infrared sensor 5, and a water hammer elimination assembly.

[0022] The spray chamber 1 has an inlet 2 and an outlet 3 at both ends. A conveyor belt 4 passes through the inlet 2 and outlet 3 inside the spray chamber 1. A wastewater tank 6 is located below the conveyor belt 4 inside the spray chamber 1. The wastewater tank 6 is connected to a waste discharge pipe 7. The object to be cleaned is transported to the spray chamber 1 on the conveyor belt for spray cleaning. The wastewater generated during cleaning is collected in the wastewater tank 6 and discharged through the waste discharge pipe 7.

[0023] The spray assembly is located at the upper end of the spray chamber 1 and faces the conveyor belt 4. The spray assembly includes a water inlet pipe 9 fixed to the upper end of the spray chamber 1. The water inlet pipe 9 is connected to an external high-pressure water supply device. The upper end of the water inlet pipe 9 extends upward out of the spray chamber 1 and is connected to a solenoid valve 10. The lower end of the water inlet pipe 9 extends into the spray chamber 1 and is connected to a plurality of spray heads 12. The plurality of spray heads 12 are evenly distributed along the width direction of the conveyor belt 4.

[0024] Infrared sensor 5 is located at inlet 2 and faces the upper end of conveyor belt 4. Infrared sensor 5 is used to sense whether there is an object to be cleaned on conveyor belt 4. When an object to be cleaned is sensed to enter, solenoid valve 10 is opened. The opening time of solenoid valve 10 is set according to the actual situation and continues until the object to be cleaned has passed all the spray components.

[0025] A water hammer elimination component is connected to the water inlet pipe 9 and located in the direction away from the solenoid valve 10 and away from the spray chamber 1. When the solenoid valve 10 is opened and closed quickly, the water hammer phenomenon in the water inlet pipe 9 can be eliminated, thereby preventing the pipe from loosening and thus preventing leakage.

[0026] In a preferred embodiment, the water hammer elimination assembly includes a tank 13 with an inner cavity 14. The length of the inner cavity 14 is perpendicular to the water inlet pipe 9. One end of the inner cavity 14 is connected to the water inlet pipe 9. A sliding piston 15 is fitted inside the inner cavity 14. The tank 13 has an air inlet 17 connected to the other end of the inner cavity 14, and the air inlet 17 is equipped with a valve. A pressure gauge 16 is mounted on the tank 13, with its probe located at the same end of the inner cavity 14 connected to the air inlet 17. Air is added to the inner cavity 14 through the air inlet 17, thereby applying pressure to the portion of the inner cavity 14 between the flushing port and the piston 15. When the solenoid valve 10 is quickly opened and closed, the high-pressure water flow in the water inlet pipe 9 enters the inner cavity 14 and pushes the piston 15, thereby reducing the pressure of the high-pressure water flow and eliminating the water hammer phenomenon.

[0027] In a preferred embodiment, a level sensor 8 is installed on the inner wall of the wastewater tank 6, and the level sensor 8 is positioned near the upper end of the wastewater tank 6. Because the wastewater generated during cleaning contains many impurities, it can easily cause blockage of the wastewater discharge pipe 7. When the wastewater discharge pipe 7 is blocked, the wastewater discharge speed slows down, causing excessive accumulation of wastewater in the wastewater tank 6. To prevent the wastewater in the wastewater tank 6 from overflowing, the level sensor 8 is used to sense the liquid level of the wastewater in the wastewater tank 6.

[0028] In a preferred embodiment, the spraying assembly is provided in multiple sets, and the multiple sets of spraying assemblies are distributed sequentially at intervals along the conveying direction of the conveyor belt 4.

[0029] In a preferred embodiment, the lower end of the water inlet pipe 9 is connected to a plurality of spray heads 12 via a horizontally arranged distribution pipe 11. The middle part of the distribution pipe 11 is connected to the lower end of the water inlet pipe 9. The two ends of the distribution pipe 11 are sealed. The length of the distribution pipe 11 spans the width of the conveyor belt 4. The plurality of spray heads 12 are connected to the lower end of the distribution pipe 11.
