This utility model relates to the field of reverse osmosis treatment technology and proposes a self-cleaning filter device with an internal RO filter screen. The device includes a housing, a guide pipe coaxially fixed inside the housing, and an RO membrane assembly wound around the guide pipe. The housing contains a sludge storage chamber, a purification chamber, a concentrate chamber, and a clean water chamber arranged sequentially along the water inlet direction. The RO membrane assembly is placed in the purification chamber. A guide hole is provided inside the housing to connect the purification chamber and the concentrate chamber. In this utility model, the sludge storage chamber is equipped with a first elastic plug and a second elastic plug to control the opening and closing of the raw water inlet pipe and the drain pipe. The structural design of the first and second elastic plugs in conjunction with the guide pipe enables the device to have a backwashing function. Pressurized clean water can be injected into the concentrate chamber through the backwash pipe to backwash the RO membrane assembly and the filter screen. Compared with existing technologies, this eliminates the need for frequent disassembly and cleaning of the filter screen, extending the maintenance cycle. Furthermore, it enables automatic closure of the inlet end, thus preventing wastewater diversion.

This invention discloses a high-strength, slag-resistant embedded slag-blocking wall, comprising a tundish and a slag-blocking wall body. The slag-blocking wall body is inclinedly disposed in the middle of the tundish. A bottom groove is provided at the bottom of the tundish body, and side grooves symmetrically arranged on the front and rear side walls of the tundish to connect with the bottom groove for accommodating the slag-blocking wall body are provided. The slag-blocking wall body includes a hollow bottom beam abutting against the inside of the bottom groove, and a laterally extending sedimentation bottom plate is fixed to the top of the hollow bottom beam. The beneficial effects are: this invention reduces the dead zone problem caused by poor steel flow at the contact point between the bottom side of the slag-blocking wall and the tundish, promotes the flow of molten steel along the guide holes of the inclined impact-resistant back plate, thereby promoting the floating of slag inclusions and improving the cleanliness of the molten steel; the slag-blocking wall body utilizes its own weight to achieve a seal at the contact point between its outer edge and the tundish, eliminating the need for additional mortar coating for sealing, improving the convenience of replacing the slag-blocking wall inside the tundish and the sealing efficiency, and increasing production efficiency.

This invention relates to the field of wafer loading technology, and more particularly to a loading platform with high-precision wafer warpage detection capabilities. The technical solution includes a wafer tray fixed above the loading platform, with vertical slots inside for placing wafers; a tray detection sensor is located below the loading platform to detect the tray's positioning status. A lifting and positioning mechanism is fixed to the platform mounting plate via a mounting base, and its electric lifting mechanism drives a connecting plate and lifting frame to move vertically; laser sensors are installed at both ends of the top of the lifting frame in a staggered V-shaped layout, located on the front and rear sides of the wafer tray respectively, forming a front-to-back scanning optical path. During scanning, the lifting frame moves the sensors upward, and the controller calculates the warpage of each wafer based on the upward and downward signals generated by the sensors combined with the lifting speed. This invention significantly improves wafer warpage detection accuracy through V-shaped through-beam scanning, effectively preventing the risk of wafer collisions in automated operations, and improving production efficiency and safety.

This invention discloses a low-resistance water circuit assembly with an integrated water pump, relating to the field of liquid chiller water circuit technology. It includes an integrated module and a pump head, inlet pipe, plate heat exchanger, PTC heater, and outlet pipe installed on the outside of the integrated module. By using an integrally cast integrated module and pump head, the water circuit piping is directly constructed within the integrated module through a one-piece molding process. This achieves water circuit connectivity between the water pump, plate heat exchanger, and PTC heater components, while solving the safety hazards associated with external piping in traditional technologies. Furthermore, it effectively reduces the production cost and weight of the water circuit assembly, facilitating its application.

The utility model relates to the technical field of high-voltage power distribution cabinets, in particular to closing equipment, which comprises a ball spline shaft assembly, a front-back driving mechanism, a rotary driving mechanism and a tool head, the driving end of the front-back driving mechanism is connected with one end of the ball spline shaft assembly and used for controlling the ball spline shaft assembly to reciprocate in the axis direction of the ball spline shaft assembly. The driving end of the rotation driving mechanism is connected with the other end opposite to one end of the ball spline shaft assembly and is used for controlling the ball spline shaft assembly to circumferentially rotate along the axis direction of the ball spline shaft assembly, so that when switching-on operation needs to be carried out, only the position of the pressing button or the rotation button needs to be in butt joint with a tool head of the equipment; after butt joint is completed, the personnel evacuate from the high-voltage power distribution cabinet to reach a safe distance, and then the front-back driving mechanism and the rotary driving mechanism can be controlled by equipment such as an industrial tablet computer to drive the ball spline shaft assembly to rotate, advance and retreat, so that automatic closing is realized.

The present invention relates to the technical field of circuit breakers, and in particular to an intelligent miniature circuit breaker with an automatic closing function, comprising a circuit breaker body and an insulating handle, wherein a closing device is fixedly connected to the front end of the circuit breaker body, an insulating handle is fixedly connected to the bottom end of the closing device, and the insulating handle is rotatably connected to the circuit breaker body, the closing device comprises a protective shell, a first motor, a first storage battery, a square column, a threaded rod and a pull rope, the front end of the circuit breaker body is fixedly connected to the protective shell, and the inner side of the top end of the protective shell is fixedly connected to the first motor. In the present invention, by providing the first motor, the first storage battery, the square column, the threaded rod and the pull rope, when it is necessary to close the circuit breaker body, a staff member controls the first motor to rotate with the threaded rod on the inner side of the square column through a control switch, and pulls the insulating handle through the square column, thereby realizing automatic closing of the circuit breaker body, which is simple to operate and convenient for the staff member to use.
