Description

Technical Field

[0001] The utility model relates to the technical field of steel manufacturing equipment, in particular to an environmentally friendly reversible conveying belt device. Background Art

[0002] During the production process, the vibrating feeder at the lower end of the limestone silo in front of the kiln and the belt in front of the kiln are started to transport the limestone raw materials into the weighing hopper in front of the kiln for weighing. When the weight in the weighing hopper in front of the kiln reaches the set weight value and the single bucket trolley reaches the bottom of the inclined bridge track, the gate at the bottom of the weighing hopper in front of the kiln opens and the limestone raw materials are placed inside the single bucket trolley. Under the action of the winch, the single bucket pours the limestone raw materials into the weighing hopper on the top of the kiln.

[0003] like Figure 1 As shown, when the double-chamber 1# kiln chamber is calcined, the 2# kiln chamber is a heat storage chamber, and the system needs to add materials to the 2# kiln chamber. At this time, the kiln top feeder 1 conveys the limestone raw materials to the 2# kiln chamber rotating hopper 3 corresponding to the top of the 2# kiln chamber through the kiln top bidirectional belt 2. During the feeding process, in order to ensure that the 2# kiln chamber rotating hopper 3 is filled with enough stone and keep the material level, the 2# kiln chamber rotating hopper 3 motor drives the reducer to rotate the 2# kiln chamber rotating hopper 3. When the weight set in the 2# kiln chamber rotating hopper 3 is reached, the kiln top feeder 1, the bidirectional belt 2, and the 2# kiln chamber rotating hopper 3 stop running. When the feeding time set by the system is reached, the 2# kiln chamber kiln barrel cover is opened, and the 2# kiln chamber rotating hopper 3, under the action of the hydraulic cylinder, puts the limestone raw materials in the hopper into the 2# kiln chamber. After the feeding is completed, the 2# kiln chamber rotating hopper 3 is lifted up, and then the 2# kiln chamber kiln barrel cover is closed. In this way, fuel is added 2-3 times in one combustion cycle.

[0004] When the double-chamber kiln is reversed, the 1# kiln chamber becomes a heat storage chamber, and the system changes the running direction of the two-way belt on the kiln top, and feeds into the 1# kiln chamber rotary hopper 4. Since the double-chamber kiln top feeding system has no obstructions and is a two-way belt feeding system, during operation, the roller drives the belt to run, and the remaining materials on the belt will fall onto the steel plate platform 5 at the bottom as the belt runs downward. The materials accumulated on the steel plate platform, such as mud and sand, are not conducive to sanitation and cleaning. During the material transmission process, dust is also easily caused to overflow. Considering the on-site environment, an environmentally friendly belt device needs to be set up to help reduce environmental pollution. Summary of the invention

[0007] In the above technical solution, a more specific solution may be: exhaust ports are provided at both ends of the casing, and the exhaust ports are connected to the dust collector at the kiln top.

[0008] Further: the scraper machine includes two sprockets arranged at both ends of the steel plate platform and chains meshing with the two sprockets, scraper plates perpendicular to the chain transmission direction are equidistantly fixed on the chain, and a wear-resistant plate is arranged on the steel plate platform inside the sealed machine casing. As the chain runs to the lower layer, the scraping surface of the scraper plate touches the wear-resistant plate, and the front and rear end heads of the wear-resistant plate are arranged beside the drop port.

[0009] Furthermore: the width of the scraper plate is equal to the width of the bidirectional belt, and as the chain runs to the upper layer, the scraping surface of the scraper plate touches the bottom surface of the belt section of the bidirectional belt running to the lower layer.

[0010] Further: a central exhaust port is provided at the middle of the upper part of the casing and the rear side of the receiving hopper, and the central exhaust port is connected to the dust collector at the kiln top.

[0011] Furthermore: the casing is a sealed casing, which is made of 10mm steel plates.
