Description

Technical Field

[0001] In the technical field of pipeline transportation, the present invention relates to a mobile universal tank opening and air extraction device for trains. Background Art

[0002] During the loading and unloading process of existing trains on the market, it is necessary to first open the train tank mouth and then install the train sealing device to seal the tank mouth. During this process, a large amount of gas in the tank will evaporate into the air, causing pollution to the environment.

[0003] Similarly, after loading and unloading, the train sealing device must be removed from the tank mouth before the train tank mouth lid can be locked. During this process, a large amount of gas in the train tank will evaporate into the air, causing pollution to the environment.

[0004] Tank trains typically transport various chemicals, such as petroleum and chemical raw materials. These substances, when released into the air, release pollutants such as volatile organic compounds (VOCs) and nitrogen oxides. These pollutants participate in atmospheric photochemical reactions, forming secondary pollutants such as ozone, which degrades air quality and harms human health. Furthermore, some gases have pungent odors that affect the quality of life of nearby residents. Summary of the Invention

[0005] The present invention aims to provide a mobile, universal, train tank opening extraction device to address the environmental pollution problem caused by the release of large amounts of gas from the tank opening during the installation or removal of the train sealing device after the tank opening is opened. The device utilizes a movable extraction hood positioned at the edge of the train tank opening to extract and recover gas volatilized from the opening.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A mobile universal train tank mouth opening and exhaust device includes an opening and exhaust hood structure, a movable adjustment base, and a crane pipe. The crane pipe is horizontally arranged on the movable adjustment base, and a ventilation hose is installed under the crane pipe through a clamping member. The ventilation hose is fixedly connected to the opening and exhaust hood structure. The opening and exhaust hood structure is auxiliary supported by the crane pipe, and a balancer is arranged on the crane pipe.

[0008] Preferably, the movable adjustment base includes a transverse slide rail support column and an electric transverse movable slider. The electric transverse movable slider is clamped on the transverse slide rail support column and slides. A rack is provided on the transverse slide rail support column. A motor is provided on the electric transverse movable slider. A gear is sleeved on the rotating shaft of the motor. The gear is engaged with the rack. The motor drives the gear to engage with the rack structure. The gear and rack are engaged and transmitted, thereby driving the entire crane pipe to move within the length range of the rack, thereby increasing the envelope range that can be covered when the range of the tank mouth position where the train stops is large. The movable design can avoid the space limit requirements of a specific sealing device and prevent interference between the gas collecting hood mechanism and the sealing mechanism.

[0009] Preferably, the open-lid exhaust hood structure includes an adjustment base, a sliding sleeve is connected to the adjustment base, a bottom ring is provided on the sliding sleeve, a fastening bolt, an intermediate layer, an outer layer and an inner layer are installed on the bottom ring, a partition plate is provided on the inner layer, the outer layer, the inner layer and the intermediate layer are divided into three cavities, a vent cover is provided at the upper end of the inner layer, a vent support is provided on the upper side wall of the outer layer, a vent cavity is installed on the vent support, a bolt seat is provided in a ring on the outer wall of the vent cavity, a stop bolt is provided on the bolt seat, and reinforcing ribs 1 and 2 are also provided at the bottom of the vent support, an exhaust hole is provided on the inner ring of the vent cover, and an air intake is provided on the inner ring of the intermediate layer.

[0010] Preferably, a handle is installed on the outer layer, the handle is provided with a handle cover, and the motor remote control is placed on the tray.

[0011] The present invention has the following advantages:

[0012] The invention's open-lid exhaust hood structure features a circular main body. The exhaust holes on the vent cover are evenly distributed around the train tank opening, ensuring uniform suction and effective recovery of harmful gases. The suction holes on the inner ring of the intermediate layer evenly distribute suction within three enclosed spaces separated by partitions, ensuring uniform suction and effective recovery of harmful gases. The sliding sleeve can be moved up and down to adjust the height of the entire exhaust hood to accommodate different tank opening heights. The tightening bolts prevent the sliding sleeve from falling off and secure it to any height. The overall structural height is no higher than the tank opening height, making it universally usable regardless of the left or right opening direction or the associated sealing device, improving versatility.

[0013] The outer support section of this invention can rotate at a wide angle and simultaneously move up and down, ensuring that the hood structure can be moved to any position and height when operated. The outer support rotation mechanism is cleverly arranged at the rotation joint of the outer support section via a transition flange. The outer support section can automatically move up and down by controlling the motor, reducing the operator's workload when lifting the hood. This improves operational efficiency and reduces workload. BRIEF DESCRIPTION OF THE DRAWINGS
