Background

Tank car is the chemical liquid transport means that chemical industry is commonly used, and in tank car transportation's in-process, the incident can appear sometimes, like the traffic accident, when taking place more serious traffic accident, can lead to the chemical liquid to take place to leak because of the jar body is impaired sometimes. Leakage of chemical fluids is a very serious accident, particularly with corrosive or toxic chemical fluids, the severity of which is self-evident. In order to reduce the influence of accidents as much as possible, the industry is specially redesigned aiming at the tank body structure, the tank body cavity is divided into a plurality of separation chambers, for example, the patent technology of the tank truck is named as 2018203303175, the tank body cavity of the technology is divided into a plurality of separation chambers, the bottom of the side wall between the adjacent separation chambers is provided with a circulation pipeline, and the circulation pipeline is provided with a control valve capable of controlling the opening and closing of the circulation pipeline, so that the aim of separating and storing chemical liquid is fulfilled, and when the tank truck encounters a traffic accident, the leakage of the chemical liquid only occurs at the corresponding damaged separation chamber, and the leakage amount of the chemical liquid is reduced.

However, I found that the tank structure has shortcomings in practical use. This is because i have found that this problem is serious after a chemical liquid leakage accident, and specifically, when a chemical liquid leakage accident occurs, although the leakage of chemical liquid only occurs at the corresponding separation chamber, the storage amount of chemical liquid in each separation chamber is not small, and if the chemical liquid is completely leaked, a large accident is caused, and it is necessary to further reduce the severity of this chemical liquid leakage accident.

This tank car leakage automatic remediation system is including tank car jar body 1, and jar internal chamber is cut apart into a plurality of independent separation cavity 2, is provided with runner pipe 3 in the bottom of two adjacent separation cavity 2, is provided with butterfly valve 4 and flange 5 in runner pipe mouth of pipe department, and flange 5 is fixed in runner pipe 3 exit, and butterfly valve 4 sets up in flange 5 next door, and butterfly valve 4 pressfitting just can realize closing runner pipe 3 towards flange 5, and butterfly valve 4 leaves flange 5 and opens runner pipe 3, and butterfly valve 4 receives a controlling means control switch action. The butterfly valve 4 control device comprises a main shaft 6, a driving bevel gear 7, a driven bevel gear 8 and a transmission shaft 9, wherein the driving bevel gear 7 and the driven bevel gear 8 are arranged at the top of the tank body 1 corresponding to each separation chamber 2, the driving bevel gear 7 and the driven bevel gear 8 are in meshed transmission, the transmission shaft 9 is arranged on the driven bevel gear 8, the bottom of the transmission shaft 9 is connected with a valve rod 10 of the butterfly valve 4, a motor 11 is arranged at one end of the main shaft 6 and used as a rotary power source, and the butterfly valve can be manually controlled by a hand wheel.

The top of the tank body 1 is provided with a water pump 12, each separation chamber 2 is internally provided with a floating piece 13, each floating piece 13 is provided with a liquid suction pipe 14, each liquid suction pipe 14 is a hose, the bottom of each floating piece 13 is provided with an ellipsoidal balancing weight 15, the ellipsoidal balancing weights 15 achieve a tumbler effect, the ellipsoidal parts of the balancing weights 15 are always located below the liquid level no matter how the liquid level changes, and the inlets of the liquid suction pipes 14 are always located below the liquid level. The top of the tank body 1 is provided with a liquid collecting pipe 16, a liquid suction branch pipe 17 and a liquid discharge pipe 18 are inserted into each separation chamber 2 from the top of the tank body 1, the liquid suction pipe 14 is connected with the liquid suction branch pipe 17, the top of each liquid suction branch pipe 17 is connected with the liquid collecting pipe 16, the liquid collecting pipe 16 is connected with the inlet of a water pump 12, the outlet of the water pump 12 is connected with a liquid separating pipe 19, the liquid separating pipe 19 is connected with each liquid discharge pipe 18, each liquid suction pipe 14 and each liquid discharge pipe 18 are respectively provided with an electromagnetic switch valve 20, the bottom of the wall body of each separation chamber 2 is provided with a pressure sensor 21, and the water pump 12, the electromagnetic switch valves 20 and the pressure sensors 21 are electrically connected with a control system.

Working principle: the control system matched with the remediation system mainly monitors the pressure change condition of each pressure sensor 21 to judge whether leakage of chemical liquid occurs. Firstly, chemical liquid is poured into the tank truck, the chemical liquid can be shunted into each separation chamber 2 through the circulation pipeline 3, the filling cannot be completed, and a certain space is reserved for further storing the chemical liquid filled in when the accident happens subsequently. For example, each divided chamber 2 is filled to two-thirds of the amount, and the filling is stopped. Then the motor 11 drives the main shaft 6 to rotate, the driving bevel gear 7 on the main shaft 6 drives the driven bevel gear 8 to rotate, and the driven bevel gear 8 drives the transmission shaft 9 to rotate, so that finally the valve rod 10 is controlled to act, the butterfly valve 4 is driven to press the flange 5, and the flow pipeline 3 is closed. The control system monitors each pressure sensor 21, the pressure sensed by each pressure sensor 21 is basically the same and basically constant in a certain narrow interval, when chemical liquid leakage occurs due to traffic accidents, the tank truck is still in a normal posture, rollover does not occur or occurs seriously, the tank truck leaks in the normal posture, the chemical liquid pressure in the separation chamber 2 corresponding to the leakage position can be gradually reduced, and at the moment, the control system monitors that the pressure of the separation chamber 2 is continuously reduced and judges that the separation chamber 2 leaks. In another case, the tank truck turns over, the pressure of the chemical liquid in the tank truck to the pressure sensor 21 changes after turning over, but the change is not continuous, if no leakage occurs, the pressure will be stabilized at a value again along with the stability of the liquid, if leakage occurs, the pressure sensor 21 in the separation chamber 2 corresponding to the leakage place will sense continuous decrease of the pressure, at this time, the control system also judges that the separation chamber leaks, and the system can start the water pump 12, so that both the two states can cause continuous decrease of the chemical liquid pressure of one separation chamber 2 sensed by the pressure sensor 21, at this time, the control system can close the electromagnetic switch valve 20 on the liquid suction branch pipe 17 corresponding to the other separation chamber 2 without leakage, only open the electromagnetic switch valve 20 on the liquid suction branch pipe 17 corresponding to the separation chamber 2 at the leakage place, and simultaneously close the electromagnetic switch valve 20 on the liquid discharge pipe 18 corresponding to the separation chamber 2, and open the electromagnetic switch valve 20 on the liquid discharge pipe 18 of other separation chambers 2. Thus, the water pump 12 can pump the chemical liquid in the leaked separation chamber 2 to other separation chambers 2, further leakage of the chemical liquid is avoided, and the accident influence is minimized.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
