[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] like Figures 1 to 3 As shown, a large-scale semi-mobile collection hood device for smoke and dust collection disclosed in this embodiment is used for collecting smoke and exhaust gas, including a fixed hood 1, a movable hood 2 and a movable device.

[0027] Both the fixed hood 1 and the movable hood 2 are constructed of carbon steel plates and are in an inverted U-shape, with open sides and a bottom. The outer diameter of the movable hood 2 is slightly smaller than the inner diameter of the fixed hood 1. The movable hood 2 is movably mounted within the fixed hood 1 via a movable mechanism. The outer opening of the movable hood 2 allows smoke to enter, while the outer opening of the fixed hood 1 interfaces with the exhaust port. The movable mechanism allows the movable hood 2 to move within the fixed hood 1, thereby extending the length of the fixed hood 1 by the distance the movable hood 2 moves.

[0028] The moving device comprises a guide rail 5, rollers 4 and a guide rail motor 3. The rollers 4 are arranged in four groups, and the four groups of rollers 4 are evenly arranged on the four corners of the bottom frame of the moving cover 2.

[0029] The guide rails 5 are installed on both sides of the bottom frame of the movable cover 2. The rollers 4 on the bottom of the bottom frame of the movable cover 2 are set on the guide rails 5, and the rollers 4 are provided with guide rail motors 3 for driving them to roll. The guide rail motor 3 drives the rollers 4 to rotate through the drive shaft to achieve displacement on the guide rails 5, and then the rollers 4 drive the connected movable cover 2 to displace on the fixed cover 1.

[0030] The length of the guide rail 5 is the length range within which the movable cover 2 can move, so it can be customized according to a length suitable for most workpieces.

[0031] Furthermore, in this embodiment, limit mechanisms are respectively provided at both ends of the guide rail 5, and the limit mechanisms include an open limit switch 7 away from the fixed cover 1 and a closed limit switch 6 close to the fixed cover 1. The displacement range of the roller 4 is limited between the open limit switch 7 and the closed limit switch 6.

[0032] Furthermore, in this embodiment, a brake is provided on the roller 4. After the movable cover 2 is displaced to a distance deemed appropriate by the staff, its movement is restricted by the brake on the roller 4, thereby fixing the position of the movable cover 2 after displacement.

[0033] Further, if Figure 4 As shown, in this embodiment, a guide device 9 is provided in the fixed cover 1 of the collecting cover. The guide device 9 adopts a multi-blade air outlet for drainage, which is used to guide the smoke and dust from the outer opening position of the movable cover 2 to the exhaust port connected to the outer opening of the fixed cover 1, while ensuring the exhaust effect, so that the working environment of the workers remains relatively comfortable.

[0034] If a trumpet-shaped air outlet is separately provided at the connection between the fixed cover 1 and the air duct of the smoke exhaust port for exhaust, air flow resistance may be generated at the position of the workpiece, thereby causing the problem of biased flow. The trumpet is connected by a multi-blade air outlet structure. The multi-blade air outlet structure uses several blades connected in parallel as air outlets, which are provided in the fixed cover 1 and are used to collect smoke and exhaust gas in the collection cover. The smoke and exhaust gas pass through the air outlet and the air duct connected to the smoke exhaust port through the trumpet to enter the purification equipment. The multi-blade air outlet structure avoids the problem of biased flow due to the position of the workpiece blocking the air outlet during processing in the collection cover.

[0035] Furthermore, in this embodiment, a ruler is provided on one side of the guide rail 5 , and the ruler is used to mark the displacement distance of the movable cover 2 to accommodate workpieces of different sizes.

[0036] Furthermore, in this embodiment, a displacement sensor and an alarm indicator light 8 are provided on the outer top wall of the movable cover 2. The displacement sensor is connected to the control system via signals, and the control system is electrically connected to the alarm indicator light 8. The alarm indicator light 8 includes both light and sound. When the displacement sensor detects that the movable cover 2 is moving, the alarm indicator light 8 emits a light and an alarm sound to remind the staff to avoid the movable cover 2 when it is moving, thereby preventing safety accidents.

[0037] In addition, to further monitor the drainage of smoke and pollutants, this embodiment is provided with an environmental monitoring mechanism and an alarm indicator light 8 on the inner wall of the mobile cover 2. The environmental monitoring mechanism is connected to the control system via signals, and the control system is connected to the alarm indicator light 8. The control system electrically controls the alarm indicator light 8 to illuminate according to a preset monitoring threshold. A red light indicates that the concentration is high and does not meet the standards, and a green light indicates that it meets the standards. This is used to monitor the smoke concentration inside the mobile cover 2.

[0038] The working principle of this embodiment is as follows:

[0039] When processing small workpieces, the movable cover 2 moves rightward toward the fixed cover 1 ( Figure 1 Retract it into the interior of the fixed cover 1 (in the direction of the arrow A).

[0040] When processing a large workpiece, the movable cover 2 moves to the left away from the fixed cover 1, thereby extending the fixed cover 1 and forming a larger collecting cover together with the fixed cover 1.

[0041] When the movable cover 2 needs to be retracted into the fixed cover 1, when the roller 4 of the movable cover 2 touches the closed position limit switch 6 during the displacement, the closed position limit switch 6 transmits a signal to the control system, and the control system controls the guide motor 3 to stop powering, and then the movable cover 2 stops displacement.

[0042] When the movable cover 2 needs to be displaced out of the fixed cover 1, when the roller 4 of the movable cover 2 touches the open position limit switch 7 during the displacement, the open position limit switch 7 transmits a signal to the control system, and the control system controls the guide motor 3 to stop powering, and then the movable cover 2 stops displacing.

[0043] During the displacement of the mobile cover 2, a signal is sent to the control system through the displacement sensor, and the control system electrically controls the alarm indicator light 8 to emit light and sound reminders to remind surrounding staff to avoid or pay attention, effectively avoiding the occurrence of safety accidents.

[0044] This utility model utilizes a semi-mobile collection hood with variable dimensions to collect dust generated during the processing of workpieces of varying sizes. This hood is simple to operate, meets the needs of diverse workpieces in the workshop, saves space, and reduces the operating costs of subsequent purification equipment. This utility model can reduce the operating costs of purification equipment while also conserving workshop floor space. This large-scale semi-mobile collection hood for dust collection is designed specifically for the specific pollutant dust collection process.
