Detailed Description

Embodiments of the present invention will be described herein with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

As shown in fig. 1 to 5, an embodiment of the present invention provides a sealing door apparatus, which includes a door body 1 provided with a door hole 10, and a sealing door device 2 mounted on the door body 1. The sealing door device 2 is capable of sealing the door opening 10.

As shown in fig. 1, the sealing door apparatus 2 includes a door seat 20 and a door cover 21 that is fitted to the door seat 20. The door seat 20 is installed in cooperation with the door hole 10 of the door body 1, and comprises a through hole corresponding to the door hole 10, and the door cover 21 is connected with the door body 1 through a hinge 3 and can rotate. The door hole 10 can be closed by closing the door base 20 and the door cover 21.

As shown in fig. 1 and 4, the door seat 20 includes a fixing seat 201 and a rotating plate 202 (see fig. 4), the fixing seat 201 is fixed to the door body 1, and the rotating plate 202 is rotatable on the fixing seat 201. In this embodiment, a sliding block assembly 203 connecting the fixed base 201 and the rotating disc 202 is adopted to enable the rotating disc 202 to rotate on the fixed base 201, wherein the sliding block assembly 203 includes a sliding rail 2030 arranged in the circumferential direction of the fixed base 201 and a plurality of sliding blocks 2031 capable of sliding on the sliding rail 2030, and the rotating disc 202 and the sliding block 2011 are fixedly mounted (see fig. 4). In other embodiments, a bearing is installed between the fixed seat 201 and the rotating disc 202 to realize the rotation of the rotating disc 202 on the fixed seat 201.

As shown in fig. 2 and 3, the turntable 202 includes a base plate 2020, and a convex ring 2021 provided on the base plate 2020, wherein the convex ring 2021 is provided with a locking structure 2021-a. The locking structure 2021-a of this embodiment is a plurality of teeth 2021-a spaced apart from each other in the circumferential direction of the protruding ring 2021, and the plurality of teeth 2021-a extend toward the center of the protruding ring 2021. The ends of the plurality of teeth 2021-a may be saw-toothed, square, circular, trapezoidal, and the like, and are not limited herein. When the door seat 20 is closed with the door cover 21, the rotating disc 201 drives the tooth portion 2021-a to move and press the door cover 21 to seal the door hole 10.

As shown in FIG. 5, one end of the tooth portion 2021-a is provided with a wedge angle, and the slope formed by the wedge angle gradually increases along the rotation direction of the turntable 201 when pressing the door cover 21. The end forming the wedge angle is the end corresponding to the door cover 21 in the state that the door seat 20 and the door cover 21 are covered. In the present embodiment, the tooth portion 2021-a can be guided to rotate on the door 21 by the rotating dial 201 by providing a wedge angle on the tooth portion 2021-a, so that the rotation is smooth and the locking is prevented.

As shown in fig. 1 and 3, the edge of the door cover 21 is provided with a plurality of grooves 210 at intervals along the circumferential direction, which are matched with the plurality of teeth 2021-a. When the door seat 20 is closed with the door cover 21, the door cover 21 is closed with the door seat 20 through the corresponding tooth portions 2021-a by the plurality of grooves 210; when the door seat 20 is closed with the door cover 21, the rotating disc 201 drives the tooth portion 2021-a to be dislocated with the groove 210, so as to press the door cover 21 to seal the door hole 10. The front end surface of the door cover 21 is further provided with a handle 211 for a user to open and close the door cover 21.

As shown in fig. 1, the sealing door apparatus 2 further includes a sealing washer 4 disposed in a sealing groove (not shown) formed in an inner wall of the through hole of the door seat 20, and the sealing washer 4 is located behind the plurality of teeth 2021-a and shields the plurality of teeth 2021-a from the axial direction of the door seat 20. As shown in FIG. 5, when the door seat 20 is closed with the door cover 21, the rotating disc 201 rotates the teeth 2021-a to displace from the grooves 210 and press the door cover 21 and the sealing gasket 4 to partially seal the door opening 10.

As shown in fig. 1-4, the sealing door apparatus 2 further includes a transmission mechanism 5 capable of driving the turntable 201 to rotate, and the transmission mechanism 5 is disposed on the door body 1 and includes a gear 50, a pin 51, and a handle 52 (see fig. 3 and 4). The gear 50 is attached to the door 1 by a pin 51, and the gear 50 can be rotated by shaking the handle 52. The turntable 201 is provided with a ring gear portion 2023 engaged with the gear 50 along the circumferential direction, and the rotation gear 50 can drive the turntable 202 to rotate. In other embodiments, a motor may be used to drive the gear 50 to rotate, but is not limited thereto. In other embodiments, the transmission mechanism 5 may also be a chain transmission, a belt transmission, or the like, which is not limited herein. The present embodiment may achieve a rotational accuracy design for the turntable 202 by selecting the size of the gear 50.

When the sealing door device 2 of the embodiment works, when the door cover 21 is closed, the door cover 21 is covered with the door base 20, the handle 52 is rotated clockwise to drive the gear 50 to rotate, the gear 50 drives the turntable 202 to rotate, the turntable 202 drives the slider 2030 to rotate counterclockwise by a slight angle, the front tooth part 2020-a of the turntable 202 firmly presses the door cover 20, meanwhile, the sealing performance of the sealing door device 2 is ensured by virtue of the sealing effect of the sealing gasket 4, and the opening and closing cycle operation of the door hole 10 is completed at this moment. When the door cover 20 is in a closed state and ready to be opened, the handle 52 is shaken leftwards and anticlockwise to drive the gear 50 to rotate, the gear 50 drives the turntable 202 to rotate, the turntable 202 drives the slider 6 to rotate clockwise by a small angle, the handle 211 on the door cover 20 is held, the door cover 2 is opened, and then the operations of maintenance, observation, feeding or discharging can be carried out.

This embodiment drives disc 202 through leading to adopting conduction mechanism 5 to rotate, and turned angle is little, adopts slider assembly 203 to make carousel 202 can rotate simultaneously to easy operation, convenience, quick, laborsaving. Meanwhile, the design of pre-tightening the door cover 21 by adopting multiple points (multiple tooth parts 2020-a) in front of the rotating disc 202 enables the door cover 21 to be designed by adopting a thin steel plate, thereby greatly reducing the weight of the door cover 21 and enabling the door cover 21 to be opened and closed in a relatively labor-saving manner. In addition, because the number of the pre-tightening tooth parts 2020-a in the front of the turntable 202 is large, the sealing effect is greatly improved, and therefore the toxic gas leakage is prevented from endangering the safety and even influencing the normal operation of the equipment. Moreover, the sliding block 2031 can be fixed by fixing parts such as bolts, so that the disassembly and replacement are very convenient.

The sealing door device of the present embodiment is a device such as a garbage combustion furnace having a high sealing requirement, which can prevent leakage of toxic gas, and may be a charging device for treating medical waste, industrial waste, household garbage, or solid waste, for example. Of course, the sealing door device of the present embodiment may also be other devices, and is not limited herein.
