This utility model relates to the technical field of deflector roller bearings for concrete mixing belt conveyors, specifically to a centrifugal self-cleaning deflector roller bearing housing. It includes a bearing housing, a blind cover, a through cover, an oil seal, and a mudguard. The blind cover and through cover are fixed to both sides of the bearing housing, respectively. The through cover is located on the transmission side and has a shaft hole in its center. An oil seal is installed inside the through cover, and a mudguard is fixedly connected to the outside of the through cover. A drainage channel is opened at the bottom of the bearing housing, and heat dissipation fins are provided on the outer surface of the bearing housing, arranged parallel to the axial direction of the bearing housing. The drainage channel also extends obliquely through the bottom of the bearing housing, with its inlet located at the lowest point of the bearing housing's inner cavity and its outlet leading to the outside. A filter screen covers the inlet of the drainage channel. The centrifugal self-cleaning deflector roller bearing housing designed in this utility model reduces contaminant contact, forms a long-lasting sealing barrier, prevents liquid accumulation in the cavity, extends wear life, achieves maintenance without disassembly, and reduces maintenance costs.

This utility model relates to the field of lower chord pipe technology and discloses a lower chord pipe fixing device, including a lower chord pipe fixing frame. The top of the lower chord pipe fixing frame is fixedly connected to a first steel cable ring, and a fixing steel wire is movably sleeved inside the first steel cable ring. A drainage slot is opened at the top of the lower chord pipe fixing frame, and a lower chord pipe fixing ring is fixedly connected to the bottom of the drainage slot. The lower chord pipe is movably sleeved inside the lower chord pipe fixing ring, and a fixing connecting frame is fixedly connected to the top of the lower chord pipe fixing frame. This utility model uses a drainage slot opened on the outside of the fixing frame at an inclined angle of 15° to quickly drain rainwater or condensate accumulated at the top, preventing water stains from forming liquid at the connection between the fixing frame and the lower chord pipe. This reduces the corrosion rate of metal parts, ensures the long-term stable fitting accuracy of the lower chord pipe fixing ring and the lower chord pipe, avoids loosening or jamming caused by corrosion, and further ensures the structural reliability of the equipment.

This invention provides a purging structure for a hemispherical valve, including a valve stem and a valve body. The valve body includes a housing and an arc-shaped body disposed within the housing. The valve stem includes an upper valve stem and a lower valve stem. The lower end of the upper valve stem is embedded in the upper end of the arc-shaped body, and the upper end of the lower valve stem is rotatably connected to the arc-shaped body. Several cleaning holes are opened near one end of the housing, and plugs are installed in the cleaning holes. An upper spacer ring is provided at the upper end of the arc-shaped body, and a lower spacer ring is provided at the bottom end of the arc-shaped body. This invention uses an arc-shaped body instead of the existing spherical valve body to reduce the overall weight of the valve. The upper and lower spacer rings can prevent backflow and liquid accumulation. When cleaning is required, the arc-shaped body is rotated to block the water inlet and open the cleaning holes. Clean water enters the internal cavity of the housing through the cleaning holes, cleaning the surface of the ceramic ball. Thus, the ceramic valve ball and its cavity can be cleaned without disassembling the ball valve, improving the service life of the ceramic ball valve without affecting production.

The invention relates to the technical field of breathing machines, and discloses an efficient filtering and heat dissipation device of a medical breathing machine, the efficient filtering and heat dissipation device comprises a filtering frame, the top of the filtering frame is fixedly connected with the breathing machine, and a filtering part is arranged in the filtering frame; the filtering component comprises a triangular frame, the surface of the triangular frame is fixedly connected with the inner wall of the breathing machine, a mounting frame is fixedly connected to the bottom of the triangular frame, a clamping groove is formed in the inner wall of the mounting frame, and two side plates are arranged in the mounting frame. When oxygen flows in the filter frame, the sieve pore plate can treat the oxygen entering the filter frame, impurities such as cotton fibers in the oxygen are prevented from entering the filter frame, the filter plate can filter the oxygen again after the sieve pore plate filters the oxygen, and the situation that the quality of the oxygen is poor due to the fact that the oxygen contains the impurities is avoided; when the oxygen in the filter frame enters the breathing machine, the filter bag can filter small particles in the oxygen again.
