Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, and particularly to an offline device for a dust collector with a sealing mechanism. Background Art

[0002] A dust collector is a device for removing or collecting solid or liquid fine particles from gas. Dust collectors can be classified into gravity dust collectors, inertial force dust collectors, centrifugal force dust collectors, washing dust collectors, filtration dust collectors, electrostatic dust collectors, and acoustic wave dust collectors according to the dust removal principle. Among them, the filtration dust collector is a purification device that uses a porous filtration medium to separate and capture solid or liquid particles in the gas, belonging to an efficient dry dust removal device. The filtration dust collector mainly includes cartridge dust collectors and bag dust collectors. Among them, the bag dust collector is more widely used. The bag dust collector can be divided into simple dust cleaning, mechanical vibration dust cleaning, reverse air flow dust cleaning, and pulse jet dust cleaning according to different dust cleaning methods.

[0003] The dust cleaning method of the bag dust collector can also be divided into online dust cleaning and offline dust cleaning. Offline dust cleaning requires the dust collector to be designed in the form of a multi-chamber combination to achieve chamber-by-chamber dust cleaning. When a certain filtration chamber needs to be dust cleaned, the filtration chamber is isolated from the main air flow, so that the filtration chamber is in an offline state, and then the filtration chamber is dust cleaned. The existing offline device of the dust collector cuts off the air flow with a lift valve, and there is still air flow under the offline filtration chamber, which disturbs the falling dust. Content of the Utility Model

[0004] Therefore, the utility model provides an offline device for a dust collector with a sealing mechanism to improve the problems existing in the above-mentioned prior art.

[0005] The technical solution of the utility model is as follows:

[0006] An offline device for a dust collector with a sealing mechanism includes an offline switching valve, a folding baffle assembly, and a hanging rail assembly. The offline device for a dust collector with a sealing mechanism is arranged in the dust removal box of the dust collector. The dust removal box is provided with multiple groups of chambers separated by partition plates. Each group of chambers includes a clean gas chamber and a dust gas chamber. The offline switching valve is arranged at the outlet of the clean gas chamber of each group of chambers. The folding baffle assembly is arranged at the junction of the dust gas chamber and the ash hopper of the dust collector. The hanging rail assembly is arranged above the folding baffle assembly. The folding baffle assembly includes multiple baffles and hinges. Adjacent two baffles are hinged with hinges. One of the two baffles at both ends is hinged to the inner wall of the dust removal box with a hinge, and the other is hung under the hanging rail assembly.

[0007] A preferred embodiment is that the hanging rail assembly includes a hanging rail, a hook, a screw, a reduction gear box and a motor. The hook is I-shaped, and a roller is provided above the hook. The roller rolls in the hanging rail. A threaded hole is provided below the hook, and a screw matching the screw is passed through the threaded hole. One end of the screw is connected to the output end of the reduction gear box, and the input end of the reduction gear box is connected to the motor. The reduction gear box is a worm gear reduction gear box, and the reduction gear box is fixed below the hanging rail. The lower end of the hook is hinged to the lifting ear, and the lifting ear is set on the baffle at the end of the folding baffle assembly.

[0008] A preferred embodiment is that the offline switching valve includes a cylinder, a valve plate and a partition, the partition is arranged at the confluence of the outlets of the clean air chambers of each group of cabins, the end of the piston rod of the cylinder is connected to the valve plate, an oblong air vent is opened on the partition, two vertical ribs are provided in the middle of the air vent, the cylinder is a double-rod cylinder, the cylinder body is connected to the vertical ribs, and a sealing ring is provided at the contact position of the valve plate and the partition.

[0009] A preferred embodiment is that the hanging rail is inclined downward in a direction away from the inner wall of the dust removal box, and a dust barrier is provided above the joint of two adjacent baffles in the folding baffle assembly. The dust barrier is made of soft material, and the two ends of the dust barrier are respectively bonded to the two baffles.

[0010] A preferred embodiment is that each folding baffle assembly includes five baffles, two hinges are provided between two adjacent baffles, and a hanging rail is provided above each folding baffle assembly, and the hanging rail is provided above the middle part of the baffle.

[0011] The working principle and beneficial effects of the utility model are:

[0012] The utility model provides a dust collector offline device with a sealing mechanism. When the dust collector is in normal operation, the offline switching valve is in an open state, and the folding baffle assembly is folded and retracted. When part of the cabin is switched to the offline state, the screw rod under the hanging rail rotates under the drive of the motor, pushing the hook to slide along the hanging rail, driving the folded baffle to unfold. When the folded baffle is fully unfolded, the offline switching valve is closed, cutting off the airflow through the cabin, and the cabin is offline. The utility model provides a dust collector offline device with a sealing mechanism, which can completely seal the offline cabin and prevent it from being affected by the airflow flowing below.
