Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and in particular relates to a filling device for a liquid storage tank. Background Art

[0002] In the chemical industry, chemical raw materials need to be prepared in reactors, and then pipes are used to transport the prepared chemical raw materials in the reactors into liquid storage tanks. Different types of chemical raw materials can be separated and stored through multiple liquid storage tanks.

[0003] When the chemical raw materials in the liquid storage tank need to be transported out, it is often necessary to use a chemical liquid transport vehicle for transportation; in the existing technology, the chemical liquid transport vehicle is first parked outside the liquid storage tank, and then the liquid storage tank uses a delivery pump and a hose to transport the chemical raw materials stored therein, and at the same time, the end of the hose is aligned with the filling port of the chemical liquid transport vehicle, and finally the filling process of the chemical liquid transport vehicle from the liquid storage tank is completed.

[0004] However, after the filling is completed and the hose leaves the chemical liquid transport vehicle, the hose is in a downward hanging state and there are chemical raw materials remaining in the hose. At this time, the chemical raw materials remaining in the hose will drip onto the ground, which may cause the chemical raw materials to pollute the surrounding environment. Utility Model Content

[0005] The purpose of the utility model is to provide a filling device for a liquid storage tank, which is conducive to filling chemical raw materials safely and conveniently.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a filling device for a liquid storage tank, comprising a plurality of delivery pumps arranged on the upper side of the liquid storage tank and used to extract chemical raw materials in the liquid storage tank, a delivery hose connected to the liquid outlet of the delivery pump at one end and used to connect to a chemical liquid transport vehicle at the other end, a platform arranged on the outer wall of the liquid storage tank and higher than the height of the chemical liquid transport vehicle, guardrails are arranged on the surrounding sides of the platform, winches are arranged on the platform and at positions corresponding to each delivery hose, a bracket is provided on the guardrail, a guide wheel is provided on the upper end of the bracket, and a connecting rope is provided on the winch, one end of which is connected to one end of the delivery hose away from the delivery pump and the other end is connected to the winch after passing around the guide wheel.

[0007] The utility model is further configured as follows: a connecting ear is provided on the outer wall of the delivery hose at one end away from the delivery pump, and a through hole for bundling a connecting rope is provided on the connecting ear.

[0008] The present invention is further configured as follows: a cover plate for covering an end of the delivery hose away from the delivery pump is provided on the lower side of the bracket.

[0009] The present invention is further configured as follows: a plurality of support arms are provided on the lower side of the platform.

[0010] The utility model is further configured as follows: an inspection ladder is provided at one end of the platform.

[0011] The present invention is further configured as follows: a fixing column extending vertically upward is provided in the middle of the platform, and a lighting lamp is provided at the upper end of the fixing column.

[0012] In summary, the present invention has the following beneficial effects:

[0013] 1. When the liquid storage tank is filling chemical raw materials into the chemical liquid transport vehicle, the chemical liquid transport vehicle is driven under the platform, and then the winch is started. The connecting rope is released through the winch, and then the end of the delivery hose away from the delivery pump can be dropped near the chemical liquid transport vehicle. The operator can then connect the end of the delivery hose to the chemical liquid transport vehicle, and then start the delivery pump to transport the chemical liquid in the liquid storage tank into the chemical liquid transport vehicle;

[0014] When filling is completed, the operator separates the end of the delivery hose from the chemical liquid transport vehicle, and then starts the winch again to wind the connecting rope through the winch. Then the connecting rope can drive the delivery hose to move upward away from the end of the delivery pump, thereby reducing the chemical raw materials dripping from the end of the delivery hose to the ground, which is ultimately conducive to safe and convenient chemical raw material filling.

[0015] 2. When the connecting rope is connected to the end of the delivery hose away from the delivery pump, the connecting ear provided on the outer wall of the delivery hose away from the delivery pump is used. The connecting ear has a through hole for bundling the connecting rope, thereby facilitating a stable connection between the connecting rope and the delivery hose.

[0016] 3. When the end of the delivery hose away from the delivery pump is driven upward by the connecting rope, the cover plate provided on the lower side of the bracket can be used to cover the end of the delivery hose away from the delivery pump, thereby sealing the end of the delivery hose through the cover plate to prevent external rainwater or debris from entering the delivery hose;

[0017] 4. Multiple support arms are provided on the lower side of the platform to provide stable support for the platform;

[0018] 5. When the delivery pump or winch needs to be repaired, the maintenance ladder can be used to quickly access the platform;

[0019] 6. When filling the chemical liquid transport truck at night, the lighting lamp at the top of the fixed column can be used to provide lighting, which is conducive to stable filling at night. BRIEF DESCRIPTION OF THE DRAWINGS
