This invention relates to the field of plastic production technology, specifically to a dry cleanroom dust removal process and treatment device for conductive and antistatic alloy plastics, comprising a treatment box, a mounting plate, a rotary drive mechanism, and a lifting mechanism. The mounting plate is disposed within the treatment box and is equipped with a filter cartridge for filtering dust from gas. The surface of the filter cartridge is provided with scrapers for cleaning the cartridge. The rotary drive mechanism drives the scrapers to rotate, scraping away impurities adhering to the filter cartridge surface. The lifting mechanism drives the scrapers to move up and down along the filter cartridge axis during rotation. This invention achieves the function of cleaning impurities adhering to the filter cartridge surface using the movement of the scrapers, thus maintaining stable filter cartridge filtration efficiency during long-term treatment. It solves the technical problem that traditional treatment devices, relying solely on backflushing for cleaning, cannot effectively handle stubborn adhering impurities and affect filtration continuity.

This invention discloses a laser cutting and blanking device for the production of structural components for concrete pump trucks, belonging to the technical field of laser cutting and blanking tools. It includes a combined support frame installed on a working plane, a support seat slidably engaged on the combined support frame, and a material-retrieving mechanism that is lifted and slidably mounted on the support seat. Discharge tables for cooperating with the material-retrieving mechanism are installed at intervals between the combined support frames. Multiple connecting frames are installed at intervals on the combined support frames. Sliding transmission blocks are installed at both ends of the support seat to drive it to slide on the combined support frame. The combined support frame serves as the foundation for the entire machine, ensuring the overall rigidity and stability of the equipment. The sliding transmission blocks can drive the support seat to slide smoothly on the combined support frame, enabling the lateral position of the material-retrieving mechanism to be adjustable, effectively improving the automation level and operating efficiency of the blanking process. Ultimately, it solves the problem of workpiece damage during transport caused by residual molten metal and slag in existing laser cutting and blanking devices.

An integrated architecture system for dual-indirect heat pump thermal management in pure electric vehicles based on R290. Currently, most pure electric vehicles have low integration levels in their thermal management systems. Typically, the battery pack circuit and air conditioning circuit are connected in parallel through a heat exchanger, while the motor and electronic control cooling circuit is an independent circuit. This results in too many system components, occupying a large amount of engine compartment space, and lacking a standardized and precise processing structure. In this invention, one end of the radiator is connected to the second refrigeration device, and a first valve body is provided between the radiator and the second four-way valve. The other end of the radiator is a double-ended connection end, which is sequentially connected to one end of the second refrigeration device through the fourth inlet / outlet and the second inlet / outlet of the second four-way valve. A third valve body is provided between the double-ended connection end of the radiator and the second four-way valve. The other end of the second refrigeration device is connected to the first inlet / outlet of the second four-way valve. The double-ended connection end of the radiator is sequentially connected to the fourth inlet / outlet of the second four-way valve through a drive motor, an electronic control unit, and a second water pump.

This invention relates to a tuned damper and a monorail for controlling vortex-induced vibration of a monorail main beam. The damper includes a damping box, a mass block assembly, a spring, a guide shaft, a guide assembly, and damping fluid. One end of the spring is connected to the bottom of the damping box cavity, and the other end is connected to the bottom of the mass block assembly. One end of the guide shaft is connected to the bottom of the damping box cavity, and the other end is connected to the top of the damping box cavity, passing through the mass block assembly. The guide assembly is fixedly connected to the mass block assembly and symmetrically arranged on both sides of the guide shaft. The damping fluid is disposed within the damping box cavity. The advantages of this invention are: 1. By limiting lateral displacement through the guide assembly, stability is increased; 2. Adjusting the base allows for adjustment of the gap between the roller and the guide shaft without affecting the vertical vibration of the mass block assembly, thus promoting stable and long-term operation of the device; 3. The mass block assembly optimizes the adjustment efficiency.

The invention relates to the technical field of magnesium sulfate production, in particular to a centrifugal separation method for magnesium sulfate production and processing, which comprises the following steps: adjusting a feeding component, atomizing and dispersing magnesium sulfate slurry, reversely conveying to the inner wall of a drum, starting centrifugal separation of the drum, synchronously scraping materials on the inner wall, and stopping to discharge solid materials after separation is completed.
