The utility model relates to a purification filter cloth bag bin top cover plate installation sealing structure which comprises a top cover plate, a cover plate groove of an annular structure is formed in the lower side of the top cover plate, a supporting ring extends into the cover plate groove, a rubber strip is installed at the groove bottom of the cover plate groove, and the two ends of the rubber strip abut against each other. A plurality of pressure applying pieces are arranged at the end of the edge of the top cover plate in the circumferential direction at intervals. According to the utility model, the technical problems that the sealing effect between the existing top cover plate and the supporting ring is poor, gas leakage is easy to occur, and the risk of gas poisoning of inspection personnel is caused can be solved.

The application relates to the technical field of ventilation fans, and discloses a ventilation fan applied to public health prevention of occupational chemical gas poisoning, which comprises a shell, a bearing connected to one side of the shell through a bearing sleeve, a motor transmission connected with an impeller shaft, the impeller shaft penetrating through the bearing and connected with an impeller, the bearing sleeve fixedly connected with a mounting disc, the mounting disc movably connected with a convex pipe with a plurality of protrusions through a mounting bearing, and the mounting disc fixedly connected with a concave pipe with a groove. The ventilation fan applied to public health prevention of occupational chemical gas poisoning takes the labyrinth sealing assembly as a whole, only needs to be inserted into a containing cavity at the end of the bearing sleeve, and corresponding bolts are tightened, so that installation is completed. The installation mode reduces the requirement for installation precision, and further improves the reliability of sealing. Meanwhile, the vibration of the impeller shaft can be isolated, and the influence of vibration on the labyrinth passage when the fan rotates is effectively reduced.

The invention relates to the technical field of metallurgy, in particular to a belt rope threading device and method for a horizontal drying sintering furnace. The invention provides a belt rope threading device of a horizontal drying sintering furnace, which comprises a belt rope threading device body and a guide fixing part, the belt rope threading device body is provided with a guide surface, the guide surface is used for being in contact with a carrier roller of a horizontal continuous annealing unit, the guide fixing part comprises a guide fixing part body, a guide surface and a fixing part, the guiding fixing part bodies are arranged at the two ends of the extending direction of the belt rope penetrating device body, the guiding face is in slope transition from the side close to the guiding face to the side away from the guiding face, and the fixing part is used for fixing a belt rope. According to the technical scheme, the safety risks such as high-altitude falling, gas poisoning, mechanical injury and heatstroke existing in the manual belt rope threading process of post personnel are avoided, the number of belt rope threading operators in the section is reduced, the belt rope threading operation time is shortened, and belt rope threading operation is safely and efficiently achieved.

The application discloses a gas poisoning first-aid device, and relates to the technical field of gas poisoning first-aid, which comprises a cylinder, the inside of which is provided with a rotatable separating component for separating the inner cavity of the cylinder into three independent chambers; the separating component comprises a separating plate, a rotating shaft and a transfer sleeve; the separating plate is arranged on the rotating shaft at equal intervals; one end of the rotating shaft penetrates through the cylinder and is connected with the transfer sleeve; the transfer sleeve is connected with a molecular sieve and an atomizer respectively; a face mask is connected with the cylinder through a valve opening degree component at one end. The device is suitable for multiple types of adaptation, and can cope with reduction, acid and organic toxic gas poisoning through three independent detoxification chambers and special detoxification modules, thereby solving the problem of single function of traditional devices; the device can automatically identify the composition of the toxic gas and switch the corresponding detoxification module, so as to save the golden first-aid time for the poisoned patient; based on the regulation mechanism of the patient's breathing pressure and frequency, the device can realize synchronous dynamic adjustment of the valve opening degree and the gas output, and is suitable for severe patients with weak breath.

The invention relates to the technical field of ventilation fans, and discloses a ventilation fan applied to public health for preventing occupational chemical gas poisoning, the ventilation fan comprises a shell, one side of the shell is connected with a bearing through a bearing sleeve, a motor is in transmission connection with an impeller shaft, the impeller shaft penetrates through the bearing and is connected with an impeller, the bearing sleeve is fixedly connected with a mounting disc, and the mounting disc is fixedly connected with the motor. The installation disc is movably connected with a protruding pipe with a plurality of protrusions through an installation bearing, and the installation disc is fixedly connected with a concave pipe with a groove. According to the ventilation fan applied to public health and used for preventing occupational chemical gas poisoning, the labyrinth sealing assembly serves as a whole, installation can be completed only by inserting the labyrinth sealing assembly into the containing cavity in the end of the bearing sleeve and screwing up the corresponding bolts, the requirement for installation precision is lowered through the installation mode, the sealing reliability is improved, and meanwhile the sealing effect is improved. Vibration of the impeller shaft can be isolated, and the influence of vibration on the labyrinth channel when the fan rotates is effectively reduced.
