Description

Technical Field

[0001] The utility model relates to the technical field of oil supply, in particular to an automatic oiling system for a transition tank. Background Art

[0002] Drying drums and boiler burners need to be continuously and stably supplied with fuel (heavy oil, diesel, etc.) when they are working. Generally, a pipe is directly connected from the fuel storage tank to the oil pump on the burner. However, when the burner is too far away from the fuel storage tank, the burner's oil pump will not be able to pump and return oil normally, or when a fuel storage tank of more than 5 cubic meters is not allowed in the production plant for reasons such as fire safety, a fuel transition tank of about 2 cubic meters needs to be set up near the burner.

[0003] After setting up the transition tank, the traditional way of filling oil is to set a manual valve at the outlet of the fuel storage tank, connect a fuel pump with a pipeline, and then connect it to the transition tank. When the factory starts production, open the manual valve, start the pump to fill the transition tank with oil until the high liquid level, then stop the pump, and then the burner extracts the fuel in the transition tank for combustion.

[0004] This working method has the following disadvantages:

[0005] 1. Manual operation is required during production and workers need to be on site all the time, which is inconvenient;

[0006] Second, the liquid level control during the oil filling process is relatively cumbersome, and starting and stopping the oil pump requires a process and time, which is prone to leakage;

[0007] 3. When the work is finished, the workers need to return to the tank area to close the manual valve. Because the fuel storage tank is full (especially the vertical storage tank) and the liquid level is high, the pressure is also very high. Even if the pump is stopped, the fuel will be slowly pressed into the transition tank through the pipeline due to the principle of the communicating vessel. When the workers return to the tank area, the manual valve is not closed, and no one finds it for a long time. After the transition tank is full, fuel leakage will occur.

[0008] The transition tank oiling system in the prior art is not only inconvenient for management operations such as opening and closing valves and starting and stopping pumps, but also poses safety risks. Utility Model Content

[0009] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides an automatic oiling system for a transition tank, thereby facilitating management operations such as valve opening and closing and pump starting and stopping, and improving the safety performance of the system.

[0010] The technical solution adopted by the utility model is as follows:

[0011] A transition tank automatic oiling system comprises a fuel storage tank, a transition tank and an oil pump, and also comprises a front-pump pipeline and a rear-pump pipeline, wherein the inlet of the oil pump is connected to the fuel storage tank through the front-pump pipeline, and the outlet of the oil pump is connected to the transition tank through the rear-pump pipeline;

[0014] It also includes a control system, and the automatic valve, liquid level meter and oil pump are all connected to the control system.

[0015] As a further improvement of the above technical solution:

[0016] The automatic valve is an electric ball valve that automatically resets when power is cut off.

[0017] A filter is arranged on the pre-pump pipeline between the fuel storage tank and the automatic valve.

[0018] The filter is a basket filter.

[0019] The outer wall of the filter is provided with a heat-insulating jacket, and the pipeline before the pump, the pipeline after the pump and the oil supply pipeline are all jacketed pipes.

[0020] A manual valve is arranged on the pipeline in front of the pump.

[0021] The liquid level gauge is a reed type liquid level gauge.

[0022] An overflow port is provided on the upper side wall of the transition tank, and the overflow port is connected to an oil drain tank.

[0031] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0032] like Figure 1 As shown, the automatic oiling system of the transition tank of this embodiment includes a fuel storage tank 1, a transition tank 8 and an oil pump 6, and also includes a pump front pipeline 4 and a pump rear pipeline 7. The inlet of the oil pump 6 is connected to the fuel storage tank 1 through the pump front pipeline 4, and the outlet of the oil pump 6 is connected to the transition tank 8 through the pump rear pipeline 7;

[0033] An automatic valve 5 is provided on the pipeline 4 before the pump;

[0034] A liquid level gauge 801 is installed on the transition tank 8, and an oil supply pipeline 9 is connected to the transition tank 8. The oil supply pipeline 9 is used to transport the fuel in the transition tank 8 to the use end;

[0035] It also includes a control system, and the automatic valve 5, the liquid level meter 801 and the oil pump 6 are all connected to the control system.

[0036] Specifically, the user end can be a fuel-using device such as a drying drum and a boiler burner. The liquid level meter 801 can be a reed-type liquid level meter. The liquid level meter 801 detects the high and low liquid levels of the fuel in the transition tank 8 and is used to control the start and stop of the oil pump 6. The automatic valve 5, the liquid level meter 801 and the oil pump 6 are all connected to the control system, and the control linkage is realized through the transmission of electrical signals. The control system integrates the start and stop of the oil pump 6, the control of the opening and closing of the automatic valve 5 and the liquid level monitoring in the transition tank 8. The specific control system can be the control platform of the drying drum or the boiler burner operating room.

[0037] By setting an automatic valve 5 and an oil pump 6 on the oil supply pipeline of the transition tank 8, installing a liquid level meter 801 on the transition tank 8, and using a control system to perform oil supply operations according to the liquid level in the transition tank 8, it is convenient for management operations such as opening and closing valves and starting and stopping pumps, thereby improving the safety performance of the system.

[0038] The automatic valve 5 is an electric ball valve that automatically resets when the power is cut off. When the system is powered off, the automatic valve 5 can be reset and closed to prevent the fuel storage tank 1 from being connected to the transition tank 8 and the transition tank 8 from leaking fuel.

[0039] like Figure 1 As shown, a filter 3 is provided on the pump front pipeline 4 between the fuel storage tank 1 and the automatic valve 5. The filter 3 is provided before the automatic valve 5 to filter impurities in the fuel to protect the automatic valve 5 and the oil pump 6 behind.

[0040] like Figure 3 As shown, the filter 3 is a basket filter, which is easy to clean and the filter element is reusable.

[0041] Specifically, the filter 3 includes a housing 301 , in which a filter basket 303 is disposed. The fluid enters the housing 301 from the inlet of the housing 301 , is filtered by the filter basket 303 , and then flows out from the outlet of the housing 301 .

[0042] like Figure 1 , Figure 3 As shown, the outer wall of the filter 3 is provided with a heat-insulating jacket 302, and the pump front pipeline 4, the pump rear pipeline 7 and the oil supply pipeline 9 are all jacketed pipes. The jacket structure is provided at the pipeline and pipe fittings where the fuel flows through for heat preservation, which is convenient for fuel transportation.

[0043] like Figure 1 As shown, a manual valve 2 is provided on the pump front pipeline 4. Specifically, the manual valve 2 can be provided on the pump front pipeline 4 between the fuel storage tank 1 and the filter 3. Normally, the manual valve 2 is in a normally open state. When the oiling system is not in use, the manual valve 2 is closed to ensure that the flow path between the fuel storage tank 1 and the transition tank 8 is double-cut off by the manual valve 2 and the automatic valve 5, which plays a double insurance role.

[0044] like Figure 2 As shown, an overflow port 804 is provided on the upper side wall of the transition tank 8, and the overflow port 804 is connected to an oil drain tank.

[0045] An alarm light 803 is installed on the transition tank 8, and the alarm light 803 is connected to the control system.

[0046] The liquid level gauge 801 is used to detect the overflow level of the fuel in the transition tank 8. When the fuel level in the transition tank 8 reaches the overflow level, the fuel flows into the oil drain pool from the overflow port 804. When the liquid level gauge 801 detects that the fuel in the transition tank 8 has reached the overflow level, the system alarms and the alarm light 803 lights up. An oil replenishing port 802 is provided on the upper part of the transition tank 8, and the oil replenishing port 802 is connected to the pump front pipeline 4.

[0047] The working process of the automatic oiling system of the transition tank of this embodiment is as follows:

[0048] When the system is working or the level meter 801 detects that the fuel level in the transition tank 8 is at a low level, the control system automatically opens the automatic valve 5, and then starts the oil pump 6 to fill the transition tank 8 with oil;

[0049] When the liquid level meter 801 detects that the fuel liquid level in the transition tank 8 is at a high level, the control system automatically shuts down the oil pump 6 and then closes the automatic valve 5;

[0050] This reciprocating action ensures that the transition tank 8 continuously and stably supplies oil to the burner. The automatic valve 5 is an electric ball valve and is of switch type. It is normally closed and has an automatic reset and closing function when power is off. Even if there is a sudden power outage during the production process, it can be closed in time to prevent leakage. This not only solves the problem of cumbersome operation during production, but also solves the problem of fuel leakage in the transition tank 8 caused by the high liquid level in the fuel storage tank 1. When the liquid level in the transition tank 8 rises due to equipment failure or other reasons and begins to flow out from the overflow port 804, the alarm light 803 switch of the control system will be triggered. The alarm light 803 will flash and the alarm will sound at the equipment site and in the control room, reminding you of the leakage so that it can be handled in a timely manner.

[0051] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
