Embodiment approach

[0031] figure 1 This is a front view schematically showing an opening and closing device according to an embodiment of the present invention. As shown in the figure, according to an embodiment of the present invention, the opening and closing device includes a conical cap 1 , a supporting connecting mechanism 2 , a sliding mechanism 3 , a driving device 4 and a cylinder 5 . In this embodiment, the cylinder 5 is a hollow cylinder, and an inlet 51 and an outlet 52 are provided thereon. As shown in the figure, the outlet 52 is provided on the side wall of the cylindrical body 5 . In this embodiment, the conical cap 1 is a conical structure, which may be a hollow cone with an open bottom end (ie, the end of the conical cap 1 facing the left side in the figure). The diameter of the bottom end of the conical cap 1 is greater than or equal to the diameter of the inlet of the cylinder 5 , which ensures that the conical cap 1 can achieve the function of closing the inlet 51 . In thi...

Abstract

The invention relates to an opening-closing device which comprises a conical cover cap, a supporting and connecting mechanism, a sliding mechanism, a drive device and a cylinder body. The conical cover cap and the sliding mechanism are arranged in the cylinder body in a mutually connected manner. The sliding mechanism is supported on the inner wall of the cylinder body. The conical cover cap and the drive device are connected with the supporting and connecting mechanism. The drive device is supported on the cylinder body. According to the opening-closing device, by the adoption of the conical cover cap, the defect that a high-temperature smoke inlet gate deforms is overcome. Moreover, the sliding mechanism is adopted for replacing a traditional simple structure, thus, the situation that due to factors like high temperature, the gate deforms slightly, is blocked or gets stuck is avoided, and use reliability is further improved. Meanwhile, as the supporting and connecting mechanism and the drive device are used, automatic control replaces labor manual operation, and safety and operability are improved effectively.

Description

technical field [0001] The invention relates to an opening and closing device, in particular to an opening and closing device for a flue gas duct passage of a particleboard dryer. Background technique [0002] Particleboard production lines usually use flue gas as the heat medium for drying wet shavings. The flue gas is powered by the fan to enter the dryer, and a flue gas passage opening and closing device will be set at the flue gas pipeline before the entrance of the dryer. When the dryer is working normally, the device is on and the flue gas is supplied normally; in case of special circumstances such as shutdown, equipment failure, fire, etc., it is necessary to immediately cut off the heat source, that is, close the flue gas passage opening and closing device in time to prevent more heat Entering the dryer, the internal temperature of the dryer rises sharply, causing the shavings to catch fire, resulting in serious damage to the equipment and major economic losses to th...
