This utility model relates to the field of powder material packaging technology, and discloses an intelligent pre-made thickener dust-free packaging device, including a material conveying system, a metering and packaging system, a sealing and conveying system, and a control system. The material conveying system consists of a buffer silo, a vacuum feeder, a receiver, an air source pump, and a Roots pump. The receiver is connected to an external finished product silo, and the vacuum feeder conveys the powder material to the buffer silo in a sealed manner. The metering and packaging system includes a lifting bottom-fill packaging machine, a weighing module, and a bag clamping device. The bag clamping device fixes the packaging bag and seals it with the outlet of the lifting bottom-fill packaging machine. The weighing module is located below the packaging bag and measures in real time. The sealing and conveying system consists of an automatic seam heat sealer and a conveyor, with the conveyor sequentially connecting the metering and packaging system and the automatic seam heat sealer. In this utility model, the entire process is sealed, resulting in a low dust emission rate and a low dust concentration in the workshop, meeting environmental protection requirements.

This utility model relates to the field of powder metallurgy equipment technology, and in particular to a magnesium oxide powder tableting device, including a base, with an operating table fixedly connected to the top of the rectangular base; it also includes a mold hole, with a mold hole circumferentially formed near the center of the top of the operating table, a spiral groove formed on the inner wall of the mold hole, and a dust outlet hole formed at one end of the spiral groove near the bottom of the mold hole, the dust outlet hole connecting to a dust collection tank along the radial direction of the operating table, the dust collection tank being located on the upper part of the operating table surrounding the mold hole; compared with traditional magnesium oxide powder tableting devices, this utility model adds a dust collection mechanism, effectively reducing the escape rate of magnesium oxide powder during tableting, reducing production costs, and utilizing the dust outlet hole to allow dust of different particle sizes to pass through, effectively preventing dust from being generated by the tableting device itself, eliminating the need for external equipment, reducing the size of the tableting device, and lowering manufacturing costs, and by adding a micro heat pipe, effectively preventing the high-temperature phase transformation of magnesium oxide powder during tableting.

This utility model relates to the field of granulator technology, specifically disclosing a feed hopper for a plastic granulator with dust removal function. The hopper includes a settling chamber with an internal dust collection structure. The dust collection structure includes mounting ports on the left, right, and rear sides of the hopper's outer wall; a dust collection plate fixedly connected to the inner wall of the settling chamber and located outside the mounting ports; and a dust collection box slidably connected inside the mounting ports. Raw materials and dust fall into the large settling chamber. Dust carried by the airflow is blocked by the inclined guide baffle and guided downwards, promoting settling. It then enters the dust collection box through micropores for centralized collection. The dust collection boxes on the left, right, and rear sides expand the dust collection area, adapting to the dust diffusion direction and reducing the dust escape rate. Furthermore, the guide baffles prevent dust from directly escaping to the feed inlet and guide the dust downwards back to the settling chamber area, promoting dust settling.

The utility model discloses a metallurgical test sample grinding device with a splash-proof structure, which comprises a base, a rack fixedly connected onto the base, a motor fixedly mounted on a top plate of the rack, a driving shaft connected to an output shaft of the motor, and a grinding seat connected to the driving shaft, and is characterized in that a dust collection bin with an open top is fixed on the base; a grinding bin matched with the grinding seat and used for grinding samples is fixed in the dust collecting bin, an upper port of the grinding bin is higher than an upper port of the grinding seat, and an upper port of the dust collecting bin is higher than an upper port of the grinding bin; a filter plate is fixed between the grinding bin and the dust collection bin, the space below the filter plate is a dust collection chamber, and one side of the dust collection chamber is connected with an air pump. The utility model aims to solve the problem that the existing grinding device with an open structure is very easy to generate particle splashing and dust dissipation in the use process.
