Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a track-detachable insert door. Background Technology

[0002] In waste gas treatment systems, gate valves are crucial functional isolation devices. Their core function is to reliably cut off and physically isolate airflow, playing a vital role in safety isolation, maintenance, system segmentation and operation scheduling, and protecting critical equipment. During system start-up, shutdown, abnormal operating conditions, or maintenance work, closing the gate valves prevents abnormally high-temperature, highly corrosive, or sparking gases from entering other systems. Therefore, they are widely used in the field of waste gas treatment.

[0003] Existing welded gate valves are prone to jamming in dusty and contaminated environments. The main reasons are as follows: Dust accumulation and intrusion: Dust and sticky particles in the exhaust gas easily intrude into the narrow gap between the gate and the valve body. With the opening and closing of the gate, these impurities accumulate and compact, eventually forming a hard deposit layer on the track and sealing surface, generating significant resistance. Corrosion and rust: Corrosive components in the flue gas cause rust on the track and gate surface. The resulting rust occupies the gap and significantly increases sliding friction. However, in existing technology, the track is fixed inside the gate, making inspection and maintenance inconvenient. Utility Model Content

[0004] To solve the above problems, this utility model provides a detachable sliding door with a track. The track is bolted into the housing. When the door panel gets stuck, the track can be detached, making it easier to check the cause of the jamming and repair the sliding door.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a detachable track door, comprising a housing, wherein a detachable track is provided inside the housing; the track is slidably connected to a door panel disposed inside the housing; and the door panel is connected to a drive device.

[0006] As a preferred technical solution of this utility model, the track is set in the housing by bolts.

[0007] As a preferred technical solution of this utility model: the housing includes a valve seat and a slide cavity.

[0008] As a preferred technical solution of this utility model: the driving device includes an opening and closing actuator disposed at the top of the insert cavity; the output end of the opening and closing actuator is connected to a lead screw; a nut seat is disposed on the lead screw; the nut seat is connected to one end of a connecting rod, and the other end of the connecting rod is connected to the door panel.

[0009] As a preferred technical solution of this utility model: the housing is further provided with a locking device, which is connected to the locking actuator.

[0010] As a preferred technical solution of this utility model: the locking device includes a first locking component and a second locking component, the first locking component and the second locking component are connected by a linkage mechanism; the output end of the locking actuator is connected to the first locking component.

[0012] This utility model has the following beneficial effects:

[0013] 1. The track is bolted inside the housing; when the door panel gets stuck, the track can be removed to facilitate inspection of the cause of the jamming and repair of the door panel.

[0014] 2. The locking device ensures the stability of the gate's closure.

Detailed Implementation

[0021] To make the objectives and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1-4 As shown in the figure, this utility model embodiment provides a detachable sliding door, including a housing 1, a door panel 2 disposed inside the housing 1, and detachable tracks 3 disposed on both sides inside the housing 1. In this embodiment, the tracks 3 are preferably bolted into the housing 1. The tracks 3 are slidably connected to the door panel 2 disposed inside the housing 1. The door panel 2 is connected to a drive device 25. When the door panel 2 is jammed, the tracks 3 can be detached, thereby facilitating inspection of the cause of jamming and repair of the sliding door.

[0023] The housing 1 includes a valve seat 4 and a slide chamber 5. The valve seat 4 is used to connect to the flue 24. The drive device 25 includes an opening and closing actuator 6 disposed on the outer side of the top of the slide chamber 5. The output end of the opening and closing actuator 6 is connected to one end of a lead screw 7, and the other end of the lead screw 7 is connected to a bearing 8 disposed at the bottom of the slide chamber 5. A nut seat 9 is rotatably connected to the lead screw 7. The lower part of the nut seat 9 is connected to one end of a connecting rod 10, and the other end of the connecting rod 10 is connected to the door panel 2. The opening and closing actuator 6 drives the lead screw 7 to rotate, causing the nut seat 9 to move along the radial direction of the lead screw 7, thereby causing the connecting rod 10 to move along the radial direction of the lead screw 7, thus realizing the up and down movement of the door panel 2 within the valve seat 4. In this embodiment, the opening and closing actuator 6 is preferably an electric opening and closing actuator 6 with a multi-turn motion and a torque of 600 N.M. To facilitate maintenance and improve maintenance efficiency, a ladder 22 is provided on the slide chamber 5.

[0024] To improve the stability of the door panel 2 when closed, a locking device 11 is also provided on the valve seat 4. The locking device 11 includes a first locking assembly 12 and a second locking assembly 13. The first locking assembly 12 includes a first rotating shaft 14, one end of which passes through a first bearing seat 15 and enters the valve seat 4, and the other end is connected to a first bearing 16 located at the bottom of the insert plate cavity 5; multiple sets of pressure blocks 21 are provided on the first rotating shaft 14. The second locking assembly 13 includes a second rotating shaft 17, one end of which passes through a second bearing seat 18 and enters the valve seat 4, and the other end is connected to a second bearing 19 located at the bottom of the insert plate cavity 5; multiple sets of pressure blocks 21 are provided on the second rotating shaft 17. In this embodiment, the pressure blocks 21 on the first rotating shaft 14 and the second rotating shaft 17 are preferably three sets. The top end of the first rotating shaft 14 is connected to the top end of the second rotating shaft 17 through a linkage mechanism 20; the first rotating shaft 14 is connected to the output end of the locking actuator 23. The locking actuator 23 is preferably an electric opening and closing actuator 6, which has an angular stroke motion and a torque of 8000 N.M.
