Description

Technical Field

[0001] The utility model belongs to the technical field of petrochemical industry, in particular to a liquid receiving device for a crane pipe vertical pipe to prevent dripping. Background Art

[0002] At present, the transportation work of the petrochemical industry mainly relies on tank trucks and trains. After the top loading tank truck operation is completed, the residual petrochemicals on the drop pipe will continue to drip when it is evacuated from the tank mouth, which not only affects the cleanliness of the work site, but also may cause a series of potential problems.

[0003] In order to deal with this problem, the common practice in the industry is to set up a liquid collecting barrel on the edge of the platform, and move the vertical pipe to the top of the liquid collecting barrel by moving the crane pipe to collect the dripping medium. However, although this method reduces the scattering of dripping media to a certain extent, it is not perfect. In the short process of the vertical pipe moving from the top of the tank mouth to the top of the liquid collecting barrel, due to the effects of gravity and inertia, the petrochemical medium remaining on the vertical pipe often drips onto the outer wall of the tank truck and the surrounding ground, causing pollution to the working environment, increasing the difficulty and cost of cleaning work, and causing serious waste of resources. In addition, sometimes it is necessary to manually climb onto the tank truck to manually hang the liquid collecting barrel on the bottom of the vertical pipe, which not only increases the workload, but also poses certain safety risks.

[0004] In order to solve this problem, we invented a vertical pipe anti-drip liquid collection device for crane pipes. Summary of the invention

[0005] The utility model aims to provide a liquid receiving device for preventing a crane pipe from dripping, so as to solve the problem of petrochemical products remaining on the surface of the vertical pipe dripping when the vertical pipe is evacuated from the tank mouth.

[0006] The present invention innovatively designs a vertical pipe anti-drip liquid collection device for crane pipes. This device abandons the traditional method of manually hanging a liquid collection bucket and instead adopts a mechanical automatic driving liquid collection bucket design, thereby greatly improving the work efficiency and safety issues.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crane pipe drop pipe anti-drip liquid receiving device, comprising a liquid receiving main body component, a flow drop pipe assembly and a flange connector, characterized in that: the flange connector is fixedly installed on the flow drop pipe assembly, and the liquid receiving main body component is installed on the flange connector.

[0008] Preferably, the liquid receiving main body component includes a driving rod, an outer sleeve, a liquid collecting barrel connecting plate, a guide tube, a rotating ring and a liquid collecting barrel.

[0009] An outer sleeve is installed above the driving rod, and the outer sleeve is fixed to the cylinder fixing plate by fixing bolts;

[0010] A mounting spacer plate is sleeved on the driving rod, and a mounting spacer and a fixing nut are sleeved on the lower part of the spacer plate;

[0011] The liquid collecting barrel connecting plate is fixed between the partition plate and the spacer, the liquid collecting barrel connecting plate can rotate around the partition plate, and a guide hole is provided on the guide tube;

[0012] A guide belt is fixed inside the guide tube to facilitate smooth sliding of the outer sleeve;

[0013] The swivel pin is connected to the cylinder fixing plate. The swivel is put on the swivel pin and can rotate around the swivel pin. The swivel slides in the guide hole.

[0014] The liquid collecting barrel is fixedly mounted on the liquid collecting barrel connecting plate by means of plum quick-release screws;

[0015] The liquid collecting barrel is composed of a liquid collecting barrel main body and a connecting elbow, and a drain valve is arranged on the connecting elbow.

[0016] Preferably, the flow drop pipe assembly includes a rotary joint flange and a connecting elbow, one end of the connecting elbow is connected to the rotary joint flange, and the other end of the connecting elbow is connected to the flow straight pipe, and the fixed flange is fixed on the flow straight pipe.

[0017] Preferably, a lock washer is installed between the spacer and the fixing nut.

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

[0019] The device is designed to automatically collect the residual liquid before the drop pipe leaves the top of the tank mouth, thereby effectively reducing the occurrence of dripping. Through this innovative design, we can not only protect the cleanliness of the working environment and reduce resource waste, but also reduce the workload of staff and improve work efficiency.

[0020] After the loading operation is completed, the vertical pipe will be lifted to the top of the tank mouth. At this time, the telescopic drive mechanism starts to work, driving the liquid collection bucket to descend smoothly. Through the ingenious S-shaped guide hole limit design, the liquid collection bucket can be accurately rotated to the bottom of the vertical pipe, ensuring that the petrochemicals remaining on the vertical pipe can be accurately dripped into the liquid collection bucket.

[0021] In this way, we can not only realize the automatic collection of residual liquid in the vertical pipe, but also avoid the situation where the medium drips on the outer wall of the tank truck and the ground, effectively protect the cleanliness of the working environment and reduce resource waste. At the same time, the design of mechanical automation also greatly reduces the labor intensity of the staff and improves the working efficiency.

[0022] Before the next loading operation, we only need to move the crane pipe to the top of the tank mouth, and then drive the telescopic mechanism again to make the liquid collection bucket rise and rotate under the limit of the S-shaped guide hole to avoid the vertical pipe. The liquid collection bucket continues to rise to the upper limit of the driving telescopic mechanism, ready for the next liquid collection operation.

[0023] The design of this anti-drip liquid collection device for the vertical pipe of the crane pipe not only solves the problem of residual liquid collection in the vertical pipe, but also improves the operating efficiency through mechanical automation, making a positive contribution to the sustainable development of the petrochemical industry.
