Description

Technical Field

[0001] This invention relates to the field of liquid chlorine storage and transfer technology, and in particular to a liquid chlorine storage device and method. Background Technology

[0002] Chlorine is a highly toxic and strongly irritating yellow-green gas that poses a serious threat to human health and the surrounding environment at room temperature and pressure. For safe storage, chlorine is typically compressed or liquefied at low temperatures into liquid chlorine, which is then stored in large tanks.

[0003] While existing technologies have implemented certain safety measures for liquid chlorine storage, numerous problems remain in practical applications. For instance, if a liquid chlorine storage tank leaks, the liquid chlorine can only be transferred to a backup storage tank. However, the transfer process to the backup storage tank is cumbersome, making it difficult to respond quickly in emergencies and potentially exacerbating the difficulty of handling the accident or causing secondary accidents.

[0004] In summary, the existing liquid chlorine storage system's backup storage tanks are difficult to move, the transfer procedures are complex, and the transfer process is time-consuming, making it impossible to quickly tow them away in an emergency, thus delaying the best opportunity for emergency response. Summary of the Invention

[0005] The main objective of this invention is to provide a liquid chlorine storage device and method, which aims to solve the technical problem that existing liquid chlorine storage tanks cannot be quickly removed.

[0006] To achieve the above objectives, the present invention provides a liquid chlorine storage device, including a main storage tank and a backup storage tank, wherein the main storage tank is connected to a top liquid outlet pipe and a liquid chlorine inlet pipe, and to a bottom liquid outlet pipe; The spare storage tank is equipped with a top inlet; The top outlet pipe is detachably connected to an outer connector and an inner connector. The outer connector is equipped with an inner valve, and the inner connector is equipped with an outer valve. Both the inner valve and the outer valve are spring valves inside the pipe. The main storage tank is arranged vertically, and the backup storage tank is arranged horizontally. The outer part of the connector is provided with a releasable and locking sleeve. The sleeve is fixed to the spare storage tank by a sleeve bracket. When the spare storage tank is dragged to the left, the sleeve bracket moves to the left, and the inner connector can pull the outer connector to the left, automatically disengaging the inner connector from the outer connector. A liquid pump is installed on the top liquid outlet pipe, and a magnetic coupling is installed on the liquid pump. The spare storage tank is movably mounted with a pump motor via a motor frame, and the pump motor is equipped with a magnetic coupling. When the pump motor moves to the right, the two magnetic couplings can couple with each other, driving the liquid pump to work, thereby drawing liquid chlorine from the main storage tank into the backup storage tank.

[0007] Furthermore, the motor frame is fixed to the spare storage tank; The motor frame is provided with a mounting port and a sliding groove; The pump motor is provided with a sliding base frame at its bottom, and the base frame is movably fitted into the sliding groove through the mounting port; A rack is fixed below the base frame, and a gear meshes below the rack. The gear is rotatably mounted on the motor frame. The pump motor is positioned by rotating the gear, which is used to adjust the distance between the magnetic couplings, thereby starting and stopping the liquid pump.

[0008] Furthermore, the motor frame is provided with a rack groove, a flange, and a shaft lug; The rack groove is adapted to the rack, and the rack is embedded in the rack groove; The rack groove is provided with a retaining edge on the right side to block the pump motor and prevent it from falling off; The shaft lugs are two symmetrically arranged and located below the motor frame; The gear is mounted on the gear shaft by an interference fit. Both ends of the gear shaft are rotatably mounted on shaft lugs. A rotating handle is provided on either side of the gear shaft.

[0009] Furthermore, the outer end of the connector is equipped with a locking bead; The outer end of the connector is provided with a limiting ring, which is located on the left side of the locking bead. The locking bead is fitted with a retaining sleeve, and the inner wall of the retaining sleeve is provided with a limiting edge. A spring is fitted onto the outer connector located between the limiting ring and the limiting edge; The limiting edge is adapted to the retaining bead, that is, when the retaining sleeve moves to the left, the limiting edge can drive the retaining bead to expand outward, and the inner connector can be inserted into or pulled out of the outer connector. When the sleeve moves to the right, the limiting edge can drive the retaining bead to retract inward, and the inner connector can be locked inside the outer connector.

[0010] Furthermore, a spring baffle is provided on the left end face of the sleeve; a retaining bead baffle is provided on the right end face; The outer end of the connector is provided with a bead groove, which is adapted to the bead, that is, the bottom diameter of the groove is smaller than the diameter of the bead, and the top diameter of the groove is larger than the diameter of the bead.

[0011] Furthermore, the sleeve is also provided with a bracket sleeve, and the sleeve bracket can be detachably installed inside the bracket sleeve by removing the nut.

[0012] Furthermore, the outlet of the liquid pump is connected to the inner head via a connector pipe; The external connector is connected to the top inlet via a connector inlet pipe; The connector inlet pipe is a flexible pipe.

[0013] Furthermore, the top outlet pipe is fixed to the pipe platform by U-bolts, and a pipe support is fixed on the pipe platform; The connector outlet pipe is fixed to the pipe support by U-bolts.

[0014] Furthermore, the method includes the following steps: S1. Transfer liquid chlorine from the liquid chlorine inlet pipe into the main storage tank; S2. When needed, release the liquid from the bottom outlet tube or pull it out from the inner connector. S3. In case of an emergency and need to transfer liquid chlorine, the inner connector is snapped into the outer connector, and the handle is turned to move the pump motor to the right, so that the two magnetic couplings are within the coupling range, thereby automatically starting the liquid pump and transferring the liquid chlorine in the main storage tank to the backup storage tank. S4. When the liquid chlorine transfer is complete or the spare storage tank needs to be moved, simply drag the spare storage tank to the left.

[0015] The beneficial effects of this invention are reflected in: In this invention, the liquid pump is started and stopped non-contactly via a magnetic coupling. The liquid chlorine transfer pipeline can be automatically shut off by connecting to the external and internal connections. It can quickly transfer liquid chlorine from the main storage tank as well as the backup storage tank. It is highly mobile and can buy more time to deal with emergencies. Attached Figure Description
