This invention discloses a calcining furnace for desulfurized gypsum, comprising a calcination zone, a uniform air distribution plate, an air inlet pipe, a first uniform air distribution zone, and a second uniform air distribution zone. Both the calcination zone and the uniform air distribution plate have rectangular cross-sections. The first uniform air distribution zone includes a first uniform air distribution hood positioned below the uniform air distribution plate, with a first uniform air distribution cone at its center. The second uniform air distribution zone includes a second uniform air distribution hood positioned below the first uniform air distribution hood, with a second uniform air distribution cone at its center. High-speed airflow ejected through the air inlet pipe enters the first and second uniform air distribution zones respectively, and then flows towards the uniform air distribution plate. Compared to using a single uniform air distribution zone to form a rectangular cross-section airflow, using two uniform air distribution zones allows for adjustment of the area of ​​the circular cross-section and the four concave triangular cross-sections, thereby adjusting the airflow flow in both zones to ensure that the airflow flow is essentially the same, resulting in uniform airflow and reducing dead zones in the calcination zone.

The utility model discloses a coating machine feedway, including the material jar, the material jar upper end is equipped with the cover through bolt and nut installation, the cover is equipped with the feed hopper on the fixed, the cover is equipped with the support on the fixed, the support is equipped with the first motor on the fixed, the first motor drive end is inserted into the support and is equipped with the screw rod fixedly, the screw rod is equipped with the drive rod of screw thread connection, drive rod both sides are through the track structure with the support sliding connection, drive rod lower extreme is equipped with the mounting frame fixedly, the mounting frame is equipped with the second motor fixedly in, the second motor drive end is crossed the mounting frame and is equipped with the rotary rod fixedly, the rotary rod one end is inserted into the material jar and is equipped with a plurality of stirring rod fixedly, make stirring rod in the coating of material jar in the stirring of can move up and down simultaneously, thereby improved the work efficiency of stirring, reduced the dead angle of stirring.

This utility model discloses a steel structure rust removal device, including an acid pickling and rust removal box, a top cover, a conduit, a drive mechanism, an air pump, a hose, an auxiliary rust removal mechanism, and a storage mesh box. The top cover is detachably clipped onto the top of the acid pickling and rust removal box. The conduit is rotatably connected to the acid pickling and rust removal box. The storage mesh box is fixedly installed on the lower half of the conduit. A diversion pipe connected to the bottom of the conduit is fixed thereto, and multiple air outlets are installed on the diversion pipe. The drive mechanism is installed on the top of the acid pickling and rust removal box and is used to drive the conduit to rotate back and forth. The air pump is fixed on the top of the acid pickling and rust removal box, and the air outlet of the air pump is connected to the top of the conduit through a hose. The auxiliary rust removal mechanism is fixedly installed on the lower half of the acid pickling and rust removal box and inserted into the acid pickling and rust removal box. This utility model, through the synergistic effect of rotation, vibration, and bubble impact, can significantly improve the efficiency of acid pickling and rust removal through multi-angle agitation, high-frequency penetration, and scouring force, eliminating dead corners and ensuring uniform and thorough rust removal.
