This invention relates to the field of wastewater treatment technology, and more particularly to an urban domestic wastewater treatment device including a treatment pump station. The top of the outer arc surface of the treatment pump station is provided with a flange inlet, and the bottom of the inner arc surface of the treatment pump station near the flange inlet is connected to a conical flow guide plate. The upper surface of the conical flow guide plate is provided with an inlet in the middle. The conical flow guide plate is a double-layered structure with an arched end inside. Through a special structural design, the water flow is guided to form a slow flow state, providing sufficient reaction time for the coalescence of tiny oil droplets. This promotes the fusion of emulsified oil droplets and dispersed oil droplets to form large oil droplets. Utilizing the physical property that the density of oil is less than that of water, the oil droplets can naturally float to the surface and form a stable floating oil layer. The entire oil-water separation process does not require additional power and can be completed solely by gravity, effectively improving the oil-water separation efficiency while reducing the energy consumption and maintenance costs of the device.

This utility model relates to the field of dynamic sand table models and discloses a magnetic replacement module for dynamic sand table models. The module includes a sand table box, a placement platform at the top, and legs fixedly connected to the bottom. A magnetic suction plate is slidably connected inside the sand table box. An adjustment assembly is located at the bottom of the sand table box, comprising a sliding column and a connecting column. The outer wall of the connecting column is slidably connected to the inside of the sand table box, while the outer wall of the sliding column is fixedly connected to the outer wall of the connecting column. A disassembly and assembly assembly is located inside the connecting column. A hydraulic rod is fixedly connected to the bottom of the sand table box. In this utility model, the hydraulic rod drives the connecting frame and sliding plate, cooperating with the sliding column and sliding groove, enabling the connecting column to slide inside the sand table box. This facilitates the adjustment of the magnetic suction plate position, allowing for convenient placement and removal of the top module. This solves the problem of inconvenient removal of the top module and improves the ease of module replacement.

The utility model relates to rice processing field, and disclose a kind of raw grain stone removing device for rice processing, including bottom plate, the top of bottom plate is provided with sieve frame, the inside of sieve frame is provided with conveyor belt, the top of bottom plate one side is provided with collection box, the top of collection box is provided with sieve box, the surface of conveyor belt and the inner chamber bottom of sieve box are respectively penetrated and are provided with several sieve grooves and second sieve groove, the top of conveyor belt is provided with three scrapers this raw grain stone removing device for rice processing, in the process of conveying raw grain by conveyor belt, by electric push rod, connecting rod and driving plate, cooperate with scraper to make smaller stone pass through sieve groove and discharge from notch by back and forth scraping of raw grain on conveyor belt, while raw grain continues to convey to sieve box to the right side and moves back and forth by driving plate cooperation, so that raw grain is discharged from second sieve groove, larger stone remains in sieve box, solve the problem that existing raw grain stone removing device is difficult to continuously and quickly remove stone in raw grain.

This application relates to the field of pipeline connection technology and discloses a connecting pipe, including: a pipe body, a first upset corrugation, and a protrusion. Both the first upset corrugation and the protrusion are located on the outer circumferential surface of the pipe body and extend circumferentially along the pipe body. Along the extension direction of the pipe body, the first upset corrugation and the protrusion are spaced apart, wherein the first upset corrugation is closer to the pipe opening than the protrusion. Thus, by using an upset corrugation processing device, excess material in the pipe body is transformed into an annular protrusion extending circumferentially along the pipe body. This design not only solves the problem of excess material removal but also fully utilizes the upset corrugation processing device, eliminating the need for specialized processing equipment for removing excess material and thus saving processing costs.
