Description

Technical Field

[0001] This utility model relates to the field of oil loading and unloading, and in particular to a novel cleaning device for railway tank cars. Background Technology

[0002] Currently, after the oil unloading operation is completed on railway tank cars, it is necessary to manually insert a 10-meter-long rubber hose into the bottom of the tank car to clean the tank. This cleaning method has the following problems:

[0003] 1. Because the hose is too long, the operator needs to insert the hose into the bottom of the tanker truck and take it out after the operation. The operation of constantly operating the hose increases the labor intensity of the operator.

[0004] 2. The end of the hose has a conductive copper wire. When it is inserted into the bottom of the tank truck, the friction between the copper wire and the bottom of the tank truck can easily cause the copper wire to break and fail, which poses a safety hazard to production operations.

[0005] 3. During use, the cleaning hose rubs back and forth against the grating plate of the pallet, damaging the outer skin of the hose and causing it to leak. This not only affects production operations but also pollutes the environment and increases maintenance costs.

[0006] 4. After the cleaning operation is completed, the operator needs to close the ball valve under the platform and then retract the hose, which is time-consuming and labor-intensive.

[0007] 5. After the cleaning operation is completed, the oil residue in the hose may flow back or drip out, polluting the environment.

[0008] Based on this, this application provides a new type of safe and convenient railway tank car cleaning device to solve the above problems. Utility Model Content

[0009] The present invention aims to solve one of the technical problems existing in the prior art. Therefore, the present invention provides a new type of safe and convenient railway tank car cleaning device.

[0010] The technical solution adopted by this utility model to solve its technical problem is:

[0011] A novel cleaning device for railway tank cars is provided, comprising a cleaning system, an arm of loading arms, and a cleaning pipe assembly connected to the cleaning system. The cleaning pipe assembly includes a first steel pipe connected to the suction pipe of the cleaning system, a second steel pipe and a third steel pipe fixed to the inner and outer arms of the arm of loading arms, respectively, an aluminum pipe detachably fixed to the vertical pipe of the arm of loading arms, and high-pressure hoses connecting the first and second steel pipes, the second and third steel pipes, and the third steel pipe and the aluminum pipe, respectively. The high-pressure hose is a high-pressure hose lined with a steel braided mesh, and its two ends are provided with steel connectors connected to the steel braided mesh. The first steel pipe is grounded through a conductor.

[0012] In some alternative embodiments, the third steel pipe is further provided with a ball valve and an oil sight glass from left to right at the end near the aluminum pipe.

[0013] In some alternative embodiments, the bottom of the aluminum tube is provided with an enlarged portion, and the bottom of the enlarged portion is provided with an aluminum sealing plate, and the aluminum sealing plate is evenly distributed with a plurality of oil inlet holes.

[0014] In some alternative embodiments, the sidewall of the enlarged portion is further provided with multiple rings of side oil inlet holes.

[0015] In some alternative embodiments, the aluminum tube is also provided with a one-way valve near its enlargement.

[0016] In some alternative embodiments, the bottom of the vertical tube is provided with a bottom-sealed insert for inserting an aluminum tube.

[0017] In some optional embodiments, the vertical tube is further provided with a plurality of C-shaped slots, the plurality of C-shaped slots being on the same axis, and the axis of the C-shaped slots being collinear with the axis of the insert.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The sweeping pipe assembly designed in this utility model is installed on the loading arm, which does not affect the normal use of the loading arm. At the same time, the loading arm can be directly switched to the sweeping mode to carry out sweeping operations after unloading is completed, which simplifies the operation process, reduces labor intensity, and improves operation efficiency.

[0020] 2. Using aluminum tubing as the sweeping tube is not only lightweight, but also has excellent static electricity conductivity, eliminating the need for additional conductive copper wires and preventing the problem of conductive copper wires breaking due to friction. At the same time, the high-pressure hose described above can conduct static electricity to the ground through the steel pipe, solving the problem of static electricity generated during sweeping operations.

[0021] 3. The aluminum tube has several oil inlet holes at the bottom, which serve as filters; it is equipped with a one-way valve to solve the problems of oil backflow and residual oil dripping affecting the environment after the air supply is cut off after the cleaning is completed.

[0022] 4. The aluminum tube adopts a detachable installation method, which allows for flexible adjustment of its position during the sweeping operation, thus facilitating the sweeping operation;

[0023] 5. The ball valve and sight glass installed on the third steel pipe allow the progress of the cleaning operation to be observed through the sight glass. After the cleaning operation is completed, the ball valve on the third steel pipe can be closed directly, eliminating the need for repeated up-and-down work on the platform and reducing labor intensity.

The loading arm 2 includes an inner arm 2.1, an outer arm 2.2, and a vertical pipe 2.3, which are direct applications of existing technologies and will not be described in detail here. The sweeping pipe assembly 3 includes a first steel pipe 3.1 connected to the suction pipe 1.1 of the sweeping system 1, and several other components fixed to the loading arm 2. The second steel pipe 3.2 and the third steel pipe 3.3 on the inner arm 2.1 and the outer arm 2.2, the aluminum pipe 3.4 detachably fixed to the vertical pipe 2.3 of the loading arm 2, and the high-pressure hose 3.5 connecting the first steel pipe 3.1 and the second steel pipe 3.2, the second steel pipe 3.2 and the third steel pipe 3.3, and the third steel pipe 3.3 and the aluminum pipe 3.4 respectively; specifically, the second steel pipe and the third steel pipe can be fixed to the inner arm and the outer arm of the loading arm respectively by pipe clamps, and the preferred detachable installation method of the aluminum pipe in this embodiment is as shown in the attached figure. Figure 2 As shown, the bottom of the vertical pipe 2.3 is provided with a bottom-sealed insert 4 for inserting aluminum pipe 3.4. During the unloading process of the loading arm, the aluminum pipe is inserted into the insert. After the loading arm is unloaded, during the tank cleaning operation, the aluminum pipe is taken out from the insert and placed in the tank cleaning area at the bottom of the pipe. The position is adjusted to complete the tank cleaning operation. After the tank cleaning is completed, the aluminum pipe is reinserted into the insert so that the aluminum pipe is moved out of the tank truck along with the loading arm.

[0035] To improve the stability of the aluminum tube and facilitate its reinsertion into the insert after the sweeping operation, as shown in the attached... Figure 1 As shown, this embodiment further includes multiple C-shaped slots 5 on the vertical tube 2.3. The multiple C-shaped slots 5 are on the same axis, which can be used to clamp the aluminum tube and ensure its stability. Preferably, the axis of the C-shaped slot 5 is collinear with the axis of the insert 4. This design allows the aluminum tube to automatically align with the insert after being inserted into the C-shaped slot, and the aluminum tube can be inserted into the insert after being moved down.

[0036] In this embodiment, the high-pressure hose 3.5 is a high-pressure hose lined with a steel braided mesh. Both ends are equipped with steel connectors 3.5.1 that connect to the steel braided mesh. The high-pressure hose connects to a steel or aluminum pipe using these steel connectors, enabling electrostatic conductivity between the aluminum pipe, the high-pressure hose, and the steel pipe. By grounding the first steel pipe via a wire, electrostatic grounding of the aluminum pipe inserted into the bottom of the tanker is achieved, resolving safety hazards caused by static electricity. In another preferred embodiment, a conductive plate is connected between the flange of the first steel pipe and the suction pipe, and the suction pipe is grounded via a wire.

[0037] Preferred options are listed below. Figure 2 As shown, the bottom of the aluminum tube 3.4 in this embodiment is provided with an enlarged portion 3.4.1, and the bottom of the enlarged portion 3.4.1 is provided with an aluminum sealing plate 3.4.2, on which a plurality of oil inlet holes a are evenly distributed. The design of the enlarged portion can increase the oil intake of the aluminum tube, and the design of multiple oil inlet holes can play a filtering role, which helps to prevent clogging of the sweeping system. Furthermore, the side wall of the enlarged portion 3.4.1 is also provided with multiple rings of side oil inlet holes b, which can increase the oil intake of the aluminum tube when the oil has a certain depth.

[0038] Example 2

[0039] Based on Example 1, as shown in the appendix Figure 1 As shown in the figure, in this embodiment, a ball valve 6 and an oil sight glass 7 are further provided from left to right at the end of the third steel pipe 3.3 near the aluminum pipe 3.4. This design allows the progress of the cleaning operation to be observed using the oil sight glass. After the cleaning operation is completed, the ball valve on the third steel pipe can be closed directly, eliminating the need for repeated up-and-down work on the platform and reducing labor intensity.

[0040] Example 3

[0041] Based on Example 1 or Example 2, as shown in the appendix Figure 2 As shown, this embodiment further includes a one-way valve 8 near the enlarged portion 3.4.1 of the aluminum tube 3.4, which can solve the problems of oil backflow and residual oil dripping affecting the environment after the gas source is cut off after the cleaning is completed.
