The invention discloses a concrete manhole cover pouring mold and a pouring method thereof, belonging to the technical field of construction engineering. A concrete manhole cover pouring mold, including a workbench, the two side walls of the workbench are connected with a support seat, the outer wall of the support seat is connected with a motor, the top outer wall of the workbench is connected with two support plates, and the outer walls of the two support plates are connected There is a first screw rod, the output end of the motor passes through the support plate and is fixedly connected with the first screw rod, the outer walls of the two first screw rods are threaded with sleeves, and the top outer walls of the two sleeves are respectively connected with the first set of screw rods. The mold and the second set of molds, the first set of molds and the second set of molds are movable against each other, and a pouring cavity is arranged between the first set of molds and the second set of molds; the invention controls the operation of the motor to make the first set of molds and the second set of molds The two sets of molds are separated, which is convenient for quick demoulding of the pouring parts, and the mold is cleaned during the demoulding process to ensure that the inner side of the mold is flat, thereby saving manpower and improving work efficiency.

The invention discloses an integrated two-phase anaerobic desulfurization reactor and a wastewater treatment method thereof and belongs to the field of wastewater treatment devices.The integrated two-phase anaerobic desulfurization reactor comprises a desulfurization reaction tank and a methane-producing reaction tank which are of an integrated structure, wastewater enters the desulfurization reaction tank and the methane-producing reaction tank and is processed sequentially, and the desulfurization reaction tank and the methane-producing reaction tank are separated by a separation wall and communicated by an effluent weir.According to the wastewater treatment method of the integrated two-phase anaerobic desulfurization reactor, the integrated two-phase anaerobic desulfurization reactor can be applied to treatment of high-concentration sulfate wastewater and high-concentration organic wastewater by single reaction step of desulfurization action and methane production reaction and has the advantages that the desulphurization efficiency is high, the resistance to impact load is high, the mixing state is good, and the occupied area is small.

The invention discloses a resource recommendation method, device, equipment and storage medium. The method includes: receiving a resource recommendation request; obtaining a candidate resource set according to the geographic location where the recommendation request is issued and the resource content within a preset range; The self-related parameters and interaction-related parameters of all candidate resources in the candidate resource set; from the self-related parameters and the interactive-related parameters, the quality score table of the candidate resource set is obtained; A recommended resource is determined from the candidate resource set, and the recommended resource is sent. The present invention can automatically screen and recommend nearby high-quality resource content for the target client user, improve the user's experience, and enhance the user viscosity of the corresponding client.

The invention provides a conical roller bearing for a differential mechanism. The conical roller bearing comprises an outer ring, an inner ring, a roller and a retainer, wherein the roller comprises abig end and a small end; the retainer comprises an annular concave part located at the small end of the roller; the annular concave part is arranged toward the outer side of the bearing along the axis of the roller; the annular concave part comprises an oil throwing surface arranged at a part close to the outer ring of the bearing; the oil throwing surface is obliquely arranged toward the outer side of the bearing; and a flow limiting channel is formed through an inner edge of the annular concave part and the inner ring of the bearing. The invention provides the conical roller bearing for thedifferential mechanism, which can prevent excessive lubricating oil from entering the bearing and reduce the extra loss.
