Description

Technical Field

[0001] The utility model relates to the technical field of transport tanker loading, in particular to a chemical solution tanker loading system. Background Art

[0002] The aqueous solution of glyoxylic acid is transported by tank trucks. Before loading, the tank needs to be cleaned. Currently, water pipes are used for cleaning. It is difficult to clean every part of the tank with water pipes. Operators need to enter the tank for cleaning, which is time-consuming and labor-intensive. In addition, after the tank is cleaned, a loading crane is used to transport the product into the tank. After the existing crane is loaded, liquid is accumulated inside. When the loading area is withdrawn, the product liquid will flow on the outer wall of the tank. Due to the nature of the product, the product liquid flowing outside the tank is very difficult to clean. It takes time to clean it manually, which prolongs the loading time and greatly reduces work efficiency. Utility Model Content

[0038] The utility model provides a chemical solution tanker loading system, comprising a cleaning device 1 and a lifting pipe 2. The cleaning device 1 is used to clean a tank body 3 of a transport tanker, and the lifting pipe 2 is used to transport the chemical solution into the tank body 3.

[0039] The cleaning device 1 includes a first water pipe 11 and a second water pipe 12, which are used to extend into the tank body 3 of the transport tank truck to clean the inside of the tank body 3. The top of the first water pipe 11 is used to extend out of the tank body 3 and connect to the water tank 4. A rotating joint 13 is provided on the first water pipe 11. The second water pipe 12 is connected to the bottom end of the first water pipe 11, and the second water pipe 12 is perpendicular to the first water pipe 11. A rotatable spray device 14 is provided at the end of the second water pipe 12; the rotatable spray device 14 includes a fixed end 143 connected to the second water pipe 12, and a first spray head 141 and a second spray head 142 connected to the fixed end 143. The directions of the first spray head 141 and the second spray head 142 form an angle, and the first spray head 141 and the second spray head 142 are configured to rotate around the axis of the fixed end 143 under the action of water pressure.

[0040] The water tank 4 can be connected to the first water pipe 11 through other water pipes to deliver high-pressure water to the first water pipe 11 and the second water pipe 12. The high-pressure water is sprayed toward the inner wall of the tank body 3 through the first spray head 141 and the second spray head 142 of the rotatable spray device 14 to clean the residual solution. The first spray head 141 and the second spray head 142 rotate under the action of water pressure, thereby increasing the spray range.

[0041] By rotating the rotating joint 13 to rotate the first water pipe 11 around its own axis, the second water pipe 12 and the rotatable spray device 14 can rotate in the tank body 3, further increasing the spray range. The rotatable spray device 14 rotates one circle in the tank body 3 to fully clean the inner wall of the tank body 3.

[0042] To facilitate the rotation of the first water pipe 11 , a hand wheel 16 may be provided on the rotary joint or the first water pipe 11 , and the staff may rotate the first water pipe 11 by the hand wheel 16 to rotate the second water pipe 12 and the rotatable spray device 14 in the tank body 3 .

[0043] The water outlet of the crane pipe 2 forms a ball seat 21, and a movable ball 22 is arranged in the ball seat 21. The movable ball 22 is hollow inside and has multiple through holes. A part of the movable ball 22 is located inside the ball seat 21, and a part of the movable ball 22 is located outside the ball seat 21. The chemical solution transported by the crane pipe 2 can enter the movable ball 22 through the through holes inside the ball seat 21, and then spray out through the through holes outside the ball seat 21. The movable ball 22 is configured to rotate in the ball seat 21 driven by the water flow, and can buffer and disperse the solution transported by the crane pipe 2, so as to avoid the solution from being concentratedly sprayed toward the liquid surface when the liquid level in the tank body 3 is high, causing the liquid to splash out.

[0044] The crane pipe 2 is connected with an air pipe 23, and an air inlet valve 24 is arranged on the air pipe 23. The air pipe 23 is used to connect a pressure gas source. In detail, the crane pipe 2 is also provided with a liquid inlet valve 25, and the liquid inlet valve 25 is located at the entrance of the crane pipe 2. When the chemical solution is transported to the tank body 3 through the crane pipe 2, the liquid inlet valve 25 is opened, and the air inlet valve 24 is closed. After the crane pipe 2 is loaded, the liquid inlet valve 25 is closed, and the air inlet valve 24 is opened. The pressure gas is transported into the crane pipe 2 through the air pipe 23, and all the residual solution in the crane pipe 2 is discharged into the tank body 3. Then, the crane pipe 2 is taken out from the tank body 3, which can prevent the residual solution from dripping on the outer wall of the tank body 3 when the crane pipe 2 is taken away, thereby avoiding increasing the cleaning work and affecting the work efficiency.

[0045] Specifically, Figure 2 As shown, the direction of the second spray head 142 is perpendicular to the extension direction of the second water pipe 12, and the direction of the second spray head 142 forms an obtuse angle with the direction of the first spray head 141. The rotation axis of the first spray head 141 and the second spray head 142 coincides with the axis of the second water pipe 12. The second water pipe 12 extends transversely in the tank body 3, and when the first spray head 141 rotates under the action of water pressure, it can fully spray the side wall of the tank body 3; when the second spray head 142 rotates under the action of water pressure, it can spray the top, bottom and side wall of the tank body 3, thereby fully cleaning the tank body 3.

[0046] The first water pipe 11 and the second water pipe 12 are connected via an elbow 15 , and the first water pipe 11 and the second water pipe 12 are detachably connected to the elbow 15 , respectively, so as to facilitate the disassembly and assembly of the first water pipe 11 and the second water pipe 12 .

[0047] Furthermore, the chemical solution tanker loading system also includes a water tank 4 connected to the first water pipe 11, a chemical solution storage tank 5 connected to the crane pipe 2, and a waste liquid pool 7 connected to the tank body 3 of the transport tanker through a drain pipe 6. The water tank 4 is used to store water for cleaning the tank body 3, a control valve 9 is provided between the first water pipe 11 and the water tank 4, and a drain valve 8 is provided between the drain pipe 6 and the tank body 3.

[0048] Before loading the transport tanker, firstly, the water in the water tank 4 is sprayed into the tank body 3 for cleaning through the cleaning device 1, and the liquid in the tank body 3 is discharged into the waste liquid pool 7 through the drain pipe 6, and then the chemical solution in the chemical solution storage tank 5 is transported to the tank body 3 through the crane pipe 2. After the transportation is completed, the chemical solution remaining in the crane pipe 2 is emptied through the air pipe 23. The loading process does not require the staff to enter the tank body 3 for cleaning, nor does it need to clean the solution spilled outside the tank body 3, which saves manpower and improves work efficiency.

[0049] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
