Description

Technical Field

[0001] The utility model relates to a material leakage prevention system and belongs to the technical field of material conveying. Background Art

[0002] For the current sugar material kitchen conveying system in the silk-making workshop, the sugar material is delivered to the production site by pipeline or mobile tank.

[0003] In the actual feeding process, it was found that loose, detached, or damaged pipe joints in the pipe delivery system may cause leakage of the liquid material, or the displacement of the mobile tank may cause the tank mouth and the discharge port to be misaligned, and the liquid material cannot accurately fall into the mobile tank, causing leakage of the sugar material. If the operator fails to discover the leakage in time and suspend the feeding, a large amount of raw materials will be wasted. The feeding process is highly dependent on the operator's visual observation. In actual operation, the operator often cannot monitor in real time, and there is a great risk of leakage.

[0014] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0015] Embodiments of the present utility model: Figure 1 As shown, a leakage prevention system includes a barrel 1, a conveying pipe 2 and a mobile tank 3. The barrel 1 is connected to the mobile tank 3 through the conveying pipe 2. In this embodiment, the discharge port of the barrel 1 is permanently connected to the conveying pipe 2 and does not need to be disassembled unless there are special circumstances. The mobile tank 3 is connected to the discharge end of the conveying pipe 2. When the mobile tank 3 is filled with liquid, it can be separated from the conveying pipe 2 and moved. A first weighing device 4 is provided at the bottom of the barrel 1, and a second weighing device 5 is provided at the bottom of the mobile tank 3. The first weighing device 4 and the second weighing device 5 are both electrically connected to the controller 6.

[0016] The controller 6 is a PLC programmable controller. The controller 6 is used to receive the weight information collected by the first weighing device 4 and the second weighing device 5 in real time. The controller 6 compares the received weight information. When the difference between the weight reduction of the barrel 1 and the weight increase of the mobile tank 3 exceeds a threshold, it is determined that the conveying pipeline 2 has a leak. In this embodiment, the threshold is preferably 2kg.

[0017] In a specific embodiment, there are four first weighing devices 4, which are respectively arranged at the bottom of four supporting legs of the barrel 1, and the four first weighing devices 4 are all fixed on the ground, and the first weighing devices 4 are gravity sensors. The second weighing device 5 is an electronic ground scale.

[0018] Four gravity sensors are used to measure the weight of the barrel 1 in real time, and the electronic floor scale is used to measure the weight of the mobile tank 3 in real time.

[0019] Furthermore, the delivery pipeline 2 is provided with a pneumatic gate valve 7, which is electrically connected to the controller 6. The delivery pipeline 2 also includes an audible and visual alarm 8, which is electrically connected to the controller 6.

[0020] By setting up the pneumatic gate valve 7 and the sound and light alarm 8, when leakage of the liquid is detected, the controller 6 controls the pneumatic gate valve 7 to close to prevent the liquid from continuing to leak. The pneumatic gate valve 7 is preferably set at the connection position between the conveying pipeline 2 and the barrel 1. At the same time, the controller 6 controls the sound and light alarm 8 to send out a sound and light alarm signal to remind the staff to repair as soon as possible.

[0021] The working principle of the utility model is as follows: when working, the worker inputs the required weight information of the sweet gum material through the input device, the input device sends the weight information to the controller 6, the controller 6 controls the pneumatic gate valve 7 to open, the sweet gum material in the barrel 1 flows into the mobile tank 3 through the conveying pipe 2, the weight of the barrel 1 is weighed in real time by the first weighing device 4, and the weight of the mobile tank 3 is weighed in real time by the second weighing device 5. During the conveying process of the sweet gum material, if the difference between the weight reduced by the barrel 1 and the weight increased by the mobile tank 3 is less than 2kg, the system is normal. When the weight increased by the tank 3 is equal to the required weight of the sweet gum material, the controller 6 controls the pneumatic gate valve 7 to close, and the feeding is completed.

[0022] During the feeding process, if the difference between the reduced weight of the barrel 1 and the increased weight of the mobile tank 3 is greater than 2kg, it means that there is a leak in the system. The controller 6 controls the pneumatic gate valve 7 to close and controls the sound and light alarm 8 to send out an alarm signal to remind the staff to repair it as soon as possible.

[0023] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
