[0002] The chemical industry often needs to store and transport liquid raw materials. Common transport containers include steel tanks, fiberglass tanks, polymer plastic tanks, etc. Transport tanks have high requirements for the strength and chemical resistance of their preparation materials. For chemical materials such as liquid alkali, the transport tanks also need to have good thermal insulation properties.

[0003] After the transportation and unloading of canned materials are completed, the staff needs to clean the residual materials inside the transport tank through physical cleaning methods. The usual cleaning method is that the staff can enter the interior of the transport tank through a manhole, and the staff uses a handheld water gun to rinse the inside of the tank body. However, the liquid raw materials contained are often toxic and harmful substances, and the space inside the tank body is small, which is not convenient for the staff to move around and the staff are prone to poisoning accidents. In addition, the existing technology also has a spray pipe set above the inside of the transport tank, and a nozzle is set on the spray pipe. The nozzle sprays cleaning liquid to clean the inside of the transport tank; although this cleaning method does not require the staff to enter the interior of the transport tank, it is limited by the layout of the nozzle. The nozzle cannot fully clean all parts of the interior of the tank body, and there are often unclean places inside the transport tank. Utility Model Content

[0020] See also Figure 1-Figure 3 The present invention provides a transport tank that is easy to clean. The tank comprises a double-layer shell 1, comprising an inner shell and an outer shell. A filling cavity is provided between the inner and outer shells, and a heat-insulating layer 2 is disposed within the filling cavity. The double-layer shell 1 is made of stainless steel, and the heat-insulating layer 2 is a polyurethane foam layer. The heat-insulating layer 2 serves to insulate the raw material liquid filled within the double-layer shell 1.

[0021] A spray pipe 7 is provided above the inner cavity of the double-layer shell 1, and a plurality of first three-way pipe joints 8 are provided at intervals along the axial direction of the spray pipe 7. The lower end of the first three-way pipe joint 8 is fixedly connected to a connector 11, and the lower end of the connector 11 is rotatably connected to a rotating head 12. The rotating head 12 is connected to the first three-way pipe joint 8 through the connector 11. A second three-way pipe joint 15 is also provided on the spray pipe 7. The second three-way pipe joint 15 is connected to the liquid supply mechanism through the hose 6, so that the rotating head 12 is connected to the liquid supply mechanism. The liquid supply mechanism provides cleaning liquid to the spray pipe 7. The cleaning liquid can be a mixed solution of detergent and water. The cleaning fluid enters the rotating head 12 with a certain impact pressure, causing the rotating head 12 to rotate relative to the connecting head 11. Furthermore, the rotating head 12 is circumferentially mounted with a plurality of rotating rods 13. Several spray nozzles 14 are annularly distributed on the outer surface of the rotating rods 13. The ends of the rotating rods 13 are provided with spray nozzles 14 axially parallel to the rotating rods 13. These spray nozzles 14 are connected to the rotating head 12 via the rotating rods 13. Because the rotating head 12 can rotate relative to the connecting head 11, the spray nozzles 14 can spray cleaning fluid in all directions. In this embodiment, the number of rotating rods 13 is set to four, and the four rotating rods 13 are respectively arranged at the front, back, left, and right sides of the rotating head 12. Of course, the number of rotating rods 13 can also be set to three, and this application does not impose specific limitations.

[0023] Preferably, the bottom wall of the double-layer shell 1 is provided with fins 4, spaced at intervals along the length of the double-layer shell 1. The fins 4 accelerate heat exchange between the cooling water pipe 3 and the filled raw material liquid, improving heat exchange efficiency. Preferably, two fins 4 are provided on the double-layer shell 1 of the same cross-section, and the two fins 4 are symmetrically arranged on the bottom wall of the double-layer shell 1, allowing the solution to flow freely along the length of the bottom of the double-layer shell 1. A liquid outlet pipe is provided on the bottom wall of the double-layer shell 1 to facilitate the discharge of the solution from the bottom of the double-layer shell 1.

[0024] A support base 5 is provided on the outer wall of the double-layer shell 1. The support base 5 includes a damping spring 51, a slide plate 52, a connecting rod 53, and a fixing sleeve 54. The outer surface of the fixing sleeve 54 is mounted on the transport vehicle via fastening bolts. The fixing sleeve 54 houses a damping spring 51, one end of which is connected to the bottom wall of the fixing sleeve 54, and the other end of which is connected to the slide plate 52. The outer surface of the slide plate 52 slides with the inner wall of the fixing sleeve 54, and the upper surface of the slide plate 52 is connected to the lower surface of the double-layer shell 1 via the connecting rod 53. The damping spring 51 effectively absorbs vibrations generated during transportation, providing excellent shockproofing and ensuring safe transportation of the raw material liquid.
