Collector for sedimentation water at bottom of crude oil storage tank

Abstract

The invention relates to a collector for sedimentation water at the bottom of a crude oil storage tank. The collector comprises a sleeve arranged externally and a cylinder pipe arranged internally. A sleeve spring is arranged in the sleeve, the upper portion of the sleeve spring is fixedly connected with the inner top of the sleeve, and the lower portion of the sleeve spring is fixed to the outer surface of the cylinder pipe. A piston is arranged in the cylinder pipe, a connecting rod is connected to the piston, an outlet hole is formed in the top of the cylinder pipe, and the connecting rod passes through the outlet hole in the top of the cylinder pipe. A lock head is arranged on the upper portion of the cylinder pipe, a transverse lock hole is formed inside the lock head, a lock plate is arranged at the cross position of the lock hole and the outlet hole in the top of the cylinder pipe, two tangent holes are formed in the lock plate, and the two ends of the lock plate are connected with the sleeve spring. A piston spring is arranged in the cylinder pipe and arranged on the connecting rod in a sleeving mode, the lower portion of the piston spring is fixedly connected with the piston, and the upper portion of the piston spring is fixedly connected with the inner top of the cylinder pipe. The collector is simple in structure, convenient to operate and carry and free of the influences of external environments.

Description

technical field [0001] The invention belongs to the technical field of collection, and relates to a collector for sedimentation water at the bottom of a crude oil storage tank. Background technique [0002] As my country builds more large crude oil storage tanks in coastal port areas, the impact of corrosion on the safe operation of oil tanks will become more and more serious. At this time, it will not only cause huge economic losses and serious environmental pollution, but also affect the quality of products. quality, reduce the economic benefits of the enterprise, and even cause fires and casualties. The main reason affecting the safety of the storage tank is the corrosion of the tank bottom plate. The corrosion of the tank bottom plate has become a short board affecting the safety of the storage tank, and the tank bottom corrosion is mainly caused by the water in the crude oil deposited on the bottom of the tank. Therefore, analyzing the composition of tank bottom water h...

Problems solved by technology

However, crude oil tanks are often fully enclosed, and the water at the bottom of the tank can only be collected from the top of the tank.

Existing water collectors are mainly aimed at the collection of seawater or river water. These water collectors are lowered to the predetermined depth of seawater or river water, and the trigger device is activated to complete water collection and seal the water collector. The structure of the existing water collector Complex, cumbersome operation steps, and it is difficult to guarantee the sealing performance of the water collection cylinder of the water collector. Even if the existing gravity piston water collector can ensure the sealing of the water collection cylinder, it is not suitable for the collection of bottom water of crude oil storage tanks
