Description

Novel steel-plastic composite barrel

Technical Field

The utility model relates to a compound bucket, specific theory relates to a novel compound bucket is moulded to steel belongs to chemical container technical field.

Background

The steel-plastic composite barrel is widely applied as a packaging container for packaging and transporting dangerous chemical products or corrosive liquid, the steel-plastic composite barrel is formed by combining a steel barrel and a plastic inner container, a feeding and discharging port and a vent port (the two ports are large and small) are arranged on a barrel shell cover, the whole plastic inner container is arranged in a steel barrel shell, and a nut arranged at a barrel opening of the inner container fastens the barrel shell cover and the inner container cover together so as to complete the packaging of the liquid. However, the sealing structure of the fastening part of the barrel shell cover and the plastic liner barrel opening of the existing steel-plastic composite barrel is plane sealing, sometimes the plastic liner barrel opening sinks into the bottom plane of the barrel shell cover, after relative displacement occurs, the plastic liner barrel opening is sheltered by the bottom plane of the barrel shell cover, which is unsafe, and water leaks from the middle of an interlayer in rainy days, and liquid in the barrel easily leaks out, thereby causing serious consequences such as environmental pollution, injury to human body safety and the like.

Utility model patent 201520042729.5 discloses a compound bucket is moulded to steel that chemical packing used, include: seven components of a plastic inner container, a steel barrel protective layer, a steel barrel supporting port, an inclined plane barrel port, an interlayer foaming sealing gasket, M56 x 4 threads and a fixed outward-turning eave, wherein the plastic inner container is produced and molded by blow molding production equipment at one time, the steel barrel protective layer is arranged into a steel barrel top cover and a barrel body, the steel barrel top cover is provided with the steel barrel supporting port punched by a mold, the interlayer foaming sealing gasket is fixed outside the plastic inner container barrel port, and the inclined plane barrel port penetrates through the steel barrel supporting port so that the fixed outward-turning eave is tightly matched with the steel barrel supporting port and is tightly matched with and supported by the steel barrel supporting port; the steel drum protective layer is used for packaging the tightly fixed plastic inner container, the steel drum top cover, the steel drum supporting port, the inclined plane bung hole and the fixed outward-turning eave. Because there is the cavity between the bung hole of the compound bucket of steel plastic support mouth of this compound bucket for chemicals packing and plastics inner bag, under the circumstances such as vibration, expend with heat and contract with cold, the steel drum supports the mouth and can take place deformation, cause the bung hole that the steel drum supported mouth and plastics inner bag to take place relative position and change, the steel drum supports the bung hole that the mouth can break away from the plastics inner bag even, in addition, the steel drum supports the mouth and takes place deformation and still can cause the circular arc position rupture that the steel drum supported the mouth, thereby lead to the steel drum to support the mouth and has lost the effective protection to plastics inner bag bung hole.
