6results about How to "Avoid spill contamination" patented technology

This utility model relates to the field of printer consumables technology and discloses a printer drum that is easy to refill with toner. It includes a drum body, with inserts fixedly connected to both sides of the rear upper surface of the drum body. An upper end cover is attached to the outer walls of the two inserts. A disassembly groove is formed on the rear upper surface of the upper end cover, and sliding grooves are formed on both sides of the inner sidewall of the disassembly groove. This utility model uses a quick-release structure composed of a slider, pin, and spring, combined with a lever operation, to achieve quick disassembly and installation of the upper end cover without the need for screwdrivers or other tools. This avoids the risk of stripped screws or damage to the end cover, lowers the operational threshold, and improves operational convenience. The ring vibrator and vibration motor on the outside of the toner tube generate vibration during toner refilling, breaking up clumps of toner without the need for manual tapping, preventing toner spillage and contamination. Simultaneously, the ring structure of the ring vibrator can evenly transmit vibration force, avoiding excessive local vibration that could damage the internal photosensitive components.

The present invention discloses a raw material crushing and impurity removal device for glass production, and relates to the technical field of glass production. The present invention forms a negative pressure environment inside a crushing shell and a separation chamber through a negative pressure air pump, thereby avoiding dust generated during the crushing and separation process from overflowing and polluting the operating environment. This negative pressure design not only ensures the environmental protection of the crushing process, but also effectively reduces the loss of raw materials and improves the economic benefits of the device; by setting a sliding inclined pipe and a recovery pipeline, raw materials with larger diameters that are not fully crushed can be automatically returned to the crushing system for re-crushing. This recycling and re-crushing design greatly improves the utilization rate of raw materials, avoids the situation where large particles are not fully processed, ensures the consistency of the particle size of the final product, and can also separate and screen some impurities in the raw materials that cannot be crushed.

The utility model discloses an ultrasonic spin-vibration screen which comprises a spin-vibration screen body, a storage bin is arranged at the top of the spin-vibration screen body through a supporting rod, a machine base is arranged at the lower end of the spin-vibration screen body, the bottom of the storage bin is communicated with the spin-vibration screen body through a feeding port, and a controllable discharging mechanism is arranged on the feeding port. A rotary vibration screen is arranged in the rotary vibration screen body, a discharging port is formed in the portion, on one side above the rotary vibration screen, of the rotary vibration screen body, a lifting machine is arranged on one side of the rotary vibration screen body through a supporting frame and is arranged in an inclined mode, and the upper end of the side, close to the storage bin, of the lifting machine is connected with the top of the storage bin through a guide mechanism.
