The utility model has the advantage that the material is not easy to block.

Description

Technical Field

[0001] The utility model belongs to the technical field of hazardous waste treatment equipment, and relates to a briquetting device for hazardous waste packaging barrels. Background Art

[0002] For hazardous waste packaging metal containers, after the barrels are broken to pour out the hazardous waste liquid, in order to recycle the packaging barrels, generally they need to be briquetted to reduce the volume, and then subjected to high-temperature treatment and recycled as waste metal. The existing metal barrel briquetting equipment is prone to material jamming, that is, the pressed metal blocks are easily stuck in the mold and difficult to take out. Content of the Utility Model

[0003] The purpose of the utility model is to provide a briquetting device for hazardous waste packaging barrels in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to avoid material jamming after briquetting.

[0004] The purpose of the utility model can be realized by the following technical solutions: A briquetting device for hazardous waste packaging barrels, characterized in that it includes a bracket, two rotating frames rotatably connected to the bracket, and a pressing head. The rotating frame includes a rotating shaft and four baffles located outside the rotating shaft. The angle between adjacent baffles is 90°. When two baffles of the two rotating frames are joined and in the same horizontal plane, the four baffles form a U-shaped die opening adapted to the pressing head. The height of the U-shaped die opening is greater than half of the bottom width of the U-shaped die opening. A gear is fixedly arranged on the rotating shaft, and the two gears are meshed with each other.

[0005] Further, the bracket includes two side plates, and the two side plates and the U-shaped die opening can respectively form a rectangular die cavity.

[0006] Since the height of the U-shaped die opening is greater than half of the bottom width of the U-shaped die opening, the width of the die cavity is smaller during briquetting, and when it is flipped below the axis of the rotating shaft, its width becomes larger, and it becomes larger continuously, making it easier for the metal blocks to separate and demold after briquetting. Description of the Drawings

[0010] The following are specific embodiments of the utility model and in combination with the drawings, the technical solutions of the utility model are further described, but the utility model is not limited to these embodiments.

[0011] As Figure 1 and Figure 2 shown in the briquetting device for hazardous waste packaging barrels, it includes a bracket 1, two rotary frames rotatably connected to the bracket 1, and a pressing head 2. The rotary frame includes a rotating shaft 3 and four baffle plates 4 located outside the rotating shaft 3. The angle between adjacent baffle plates 4 is 90°. When the two baffle plates 4 of the two rotary frames are in contact and in the same horizontal plane, the four baffle plates 4 form a U-shaped die opening adapted to the pressing head 2. The height of the U-shaped die opening is greater than half of the bottom width of the U-shaped die opening. A gear 5 is fixedly arranged on the rotating shaft 3, and the two gears 5 are meshed with each other.

[0012] The bracket 1 includes two side plates 6, and the two side plates 6 and the U-shaped die opening can respectively form a rectangular die cavity.

[0013] Since the height of the U-shaped die opening is greater than half of the bottom width of the U-shaped die opening, the width of the die cavity is smaller during briquetting. When it is flipped below the axis of the rotating shaft 3, its width becomes larger, and it continuously becomes larger, making it easier for the metal block to be separated and demolded after briquetting. Substantially, through design, one side of the baffle plate 4 is farther away from the axis of the rotating shaft 3, while the other side is closer to the axis of the rotating shaft 3, so that the width change of the U-shaped die opening above and below the axis can be realized.

[0014] In order to position the rotary frame during briquetting, a hydraulic cylinder is arranged on the side of the rotary frame, and the push rod of the hydraulic cylinder can press against the baffle plate 4 in the vertical state to limit the position of the baffle plate 4.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art of the present utility model can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
