Description

Technical Field

[0001] The utility model belongs to the technical field of increased safety pre-start purge machines, and in particular relates to an increased safety pre-start purge machine. Background Art

[0002] The increased safety pre-start purge device purges the motor before starting to remove any flammable gas or dust that may be present, thereby preventing the motor from exploding due to sparks or high temperatures during the starting process. This device is crucial to ensure the safe operation of increased safety motors in explosive environments.

[0003] A patent search revealed an increased safety pre-start purge machine, a Chinese utility model with publication number CN 218108685 U. The machine comprises a main body, a base fixedly connected to the bottom of the main body, an air duct fixedly connected to one side of the main body, a dust box fixedly connected to one end of the air duct, and dust handling mechanisms disposed both inside and outside the dust box. The increased safety pre-start purge machine of the utility model directs dust through the air duct to the dust box. A first check valve prevents dust from returning from the dust box to the interior of the main body, and a second check valve prevents dust from returning from a drain pipe to the interior of the dust box. Water is sprayed through an atomizing nozzle to adsorb and agglomerate dust within the dust box. The agglomerated dust is discharged along the bottom wall of the dust box, through the second check valve, and through the drain pipe. This prevents dust from returning to the main body and the interior of the dust box and from agglomerating.

[0004] The atomizing nozzles used in the above patents are all exposed to the outside. When not in use, the atomizing nozzles cannot be protected. Over a long period of time, the atomizing nozzles are easily blocked by dust entering the dust box, thereby affecting the overall performance of the equipment and the smoothness of subsequent use, and reducing the practicality of the equipment.

The fixed pipe 14 is a metal pipe, such as a steel pipe. A through groove is provided on the top of the dust box 2 which is slidably connected to the fixed pipe 14. Two first hydraulic cylinders 11 are fixed on the inner top wall of the dust box 2 and are located in the mounting cover 4. The output shaft of the first hydraulic cylinder 11 is connected to the water separation box 12. A cleaning component is provided on the inner bottom wall of the dust box 2. The structure is simple and the operation is convenient. When not in use, the atomizing nozzle 13 on the water separation box 12 is driven by the first hydraulic cylinder 11 to move upward, so that the atomizing nozzle 13 moves to the top of the sealing block 8, which is convenient for protecting the atomizing nozzle 13 and preventing the atomizing nozzle 13 from being blocked by dust. It is relatively complete and improves the service life of the atomizing nozzle 13; a sealing gasket 10 is provided on one side of the sealing block 8 to increase the sealing performance of the two sealing blocks 8;

[0020] like Figure 2As shown, the cleaning assembly includes a second hydraulic cylinder 15 provided on one side of the dust box 2.

[0023] The working principle of the utility model is as follows: when in use, the increased safety pre-start purge machine body 3 makes the dust mirror air duct to the dust box 2, and connects the external water pipe to the fixed pipe 14 through the connector, starts the first hydraulic cylinder 11, and the first hydraulic cylinder 11 drives the water separation box 12 to move down, and the water separation box 12 drives the atomizing nozzle 13 to move down, and through the chamfered contact with the sealing block 8, the sealing block 8 moves toward the inside of the slide 7, so that the bottom of the atomizing nozzle 13 passes through the two sealing blocks 8, and the water enters the water separation box 12 through the fixed pipe 14, and then is separated by the water separation box 12. The water box 12 is diverted to the atomizing nozzle 13 and sprayed out from the atomizing nozzle 13 to adsorb and agglomerate the dust inside the dust box 2. The second hydraulic cylinder 15 is started, and the second hydraulic cylinder 15 drives the push plate 16 to move. The push plate 16 drives the dust at the bottom of the dust box 2 to be smoothly discharged from the dust box 2. After cleaning is completed, the first hydraulic cylinder 11 is started to drive the atomizing nozzle 13 to move upward, so that the atomizing nozzle 13 is moved above the sealing block 8. The elastic force of the spring 9 drives the two sealing blocks 8 to fit together, and the plug-in slot 6 is sealed to protect the atomizing nozzle 13.
