Cast tube crusher

Abstract

The invention discloses a cast tube crusher and belongs to the field of cast tube production and manufacturing. The cast tube crusher comprises a first support and a second support, wherein the first support is horizontally arranged on the ground and supported by a plurality of supporting feet; the second support is mounted on one side of the first support, and the top face of the second support is slightly lower than the first support. A plurality of parallel conveying rollers are mounted on the first support through a plurality of bearing frames symmetrically mounted on the top face of the first support. Bearings are mounted between the conveying rollers and the bearing frames. An extrusion mechanism is fixedly mounted on the surface of the second support. The cast tube crusher is a mechanical crushing device for cast tubes, the cast tubes and cement linings on the inner walls of the cast tubes can be effectively separated, the cast tubes are preliminarily crushed, and the cast tube crusher has the advantages of being high in working efficiency and capable of saving manpower and material resources compared with the prior art. Meanwhile, the crusher has the advantages of long service life, stable operation, low noise and the like.

Description

technical field [0001] The invention relates to the field of cast pipe production and manufacturing, in particular to a cast pipe crusher, which is used for crushing defective cast pipes in the production process. Background technique [0002] In the production process of the cast pipe, in order to prevent the cast pipe from rusting during use, a layer of anti-rust inner lining should be applied on the inner wall of the cast pipe. Most of these linings consist of a coating of cement. When there is a problem with the quality of the cast pipe, it is necessary to knock off the inner lining of this layer of cement material, and then return the cast pipe to the furnace for reconstruction. [0003] In the existing technology, in order to remove this layer of cement lining, most of the methods used are manually, that is, workers use simple tools such as sledgehammers to remove this layer of cement material by knocking on the cast pipe. . This method is inefficient and consumes a...

Problems solved by technology

This method is inefficient and labor-intensive. Usually, it takes about 20 to 30 minutes for a worker to completely remove the cement material in a cast pipe.

At the same time, this manual knocking method has many potential safety hazards in actual production. Workers are very prone to splashing of cast iron chips and cement blocks when knocking on the cast pipe, and the vibration generated when the sledgehammer knocks on the cast pipe is also very dangerous. Very easy to cause personal injury to workers

From another point of view, when the cast pipe after removing the cement lining of the cast pipe by manual knocking is returned to the furnace for recasting, due to the large volume of the cast pipe, it will also cause a lot of inconvenience
