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 present application relates to the technical field of house construction, and discloses a house building drainage structure, which comprises a roof, a mounting hole is opened on the roof, a drainage pipe is pierced and fixedly connected in the mounting hole, and a drainage hole is opened above the drainage pipe, A blocking structure is arranged in the drain pipe, and the blocking structure includes a first fixing ring and a second fixing ring fixedly connected with the inner wall of the drain hole, the first fixing ring is located below the second fixing ring, and the first fixing ring is provided with a first fixing ring. The fixing hole and the permeable hole, the second fixing ring is provided with a second fixing hole, the first fixing hole is provided with a fixing rod, the side of the fixing rod facing the second fixing ring is provided with a fixing plate, and the outer diameter of the fixing plate is larger than The inner diameter of the second fixing hole, the outer casing of the fixing rod is provided with a spring, and the two ends of the spring are respectively abutted with the first fixing ring and the fixing plate; when there is no force above the fixing plate, the fixing plate is in contact with the lower end surface of the second fixing ring , the application has the effect of preventing the clogging of the drain pipe.

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.

The invention discloses a breathable skin-care baby underwear which is convenient for changing diapers. It belongs to the field of baby underwear and comprises a one-piece baby underwear body. The matching leg cat ears, through the mutual cooperation of the double-piece trouser legs and the leg cat ears, facilitate the independent opening of the legs and crotch of the one-piece baby underwear body, and can be opened without taking off the one-piece baby underwear body. Complete the replacement of diapers in one step, effectively prevent the baby from catching cold due to cold, effectively ensure the baby's health, and have a good thermal effect, and the vertical texture weaving method can effectively achieve the effect of drainage, and the baby does not change the function in time When the diapers leak urine, the urine is drained to reduce the continuous wetting of the baby's skin by the urine, thereby improving the functionality of the body of the conjoined baby underwear.
