Description

Technical Field

[0001] This utility model belongs to the field of chemical material conveying technology, and in particular relates to a safety device for preventing blockage in chemical material conveying. Background Technology

[0002] Liquid and gaseous chemical materials are mainly transported by pipelines; pipelines are pipelines specifically used to transport liquid and gaseous materials. The method of transporting materials by pipeline is called pipeline transportation, which is a special mode of transportation for transporting petroleum, coal and chemical products from production sites to markets. It is a special component of trunk transportation in a unified transportation network.

[0003] Because the pipes are long and narrow, they are prone to clogging after impurities accumulate inside. Filtration is usually used to prevent particulate matter from accumulating in the pipes. When the filter screen is clogged, it needs to be replaced or cleaned. Even if the valve is closed, there is still a lot of residual chemical gas or liquid in the pipe, which may cause excessive leakage when replacing or cleaning the filter screen, posing a safety hazard.

[0004] Therefore, we propose a safety device for preventing blockages in chemical material conveying to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the safety hazards of excessive leakage when replacing or cleaning filter screens, and to propose a safety device for preventing blockage in the conveying of chemical materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safety device for preventing blockages in chemical material conveying includes a first pair of connecting pipes. One end of the first pair of connecting pipes is fixedly connected to a first flange, and the other end of the first pair of connecting pipes is fixedly connected to a sealing shell. A filter element is slidably and sealed inside the sealing shell. A second pair of connecting pipes is fixedly connected to the end of the sealing shell facing away from the first pair of connecting pipes. A second flange is fixedly connected to the end of the second pair of connecting pipes facing away from the sealing shell. A bearing bracket is fixedly connected to the outside of the second pair of connecting pipes. A pressing rod is rotatably mounted on the bearing bracket. The internal spaces of the first pair of connecting pipes, the sealing shell, and the second pair of connecting pipes are in communication. Connect the first pair of connecting pipes to the external pipeline by screwing through the first flange, and connect the second flange to the external pipeline by screwing through the second flange. Insert the filter element into the sealing shell, then pull down the pressing rod to press the pressing rod onto the filter element. Press the pressing rod down again to increase the downward pressure by levering the pressing rod, pressing the filter element down between the second pair of connecting pipes and the first pair of connecting pipes. The filter element filters solid impurities in liquids or gases, preventing clogging. Insert another filter element into the sealing shell and press down in the same way to push the first one down. Repeat the same operation to push out the first filter element inserted, making it easy to replace the filter element.

[0008] Preferably, the sealing shell includes a guide groove and a housing, the guide groove being symmetrically and fixedly connected to the upper end of the housing; the housing is fixedly connected to the first pair of connecting pipes, and the second pair of connecting pipes is fixedly connected to the housing. The filter element is inserted into the guide groove, and then pressed into the housing, so that the filter element is positioned between the first and second pair of connecting pipes, facilitating the introduction of the filter element between the first and second pair of connecting pipes.

[0009] Preferably, the sealing shell further includes a guide block, which is fixedly connected to the upper end of the guide groove. The guide block guides the filter element into the guide groove, and then guides it into the housing, facilitating the connection between the filter element and the sealing shell.

[0010] Preferably, the bearing bracket includes a collar and a fixed ring, the collar being symmetrically and fixedly connected to the fixed ring; the fixed ring is fixedly connected to the outside of the second pair of connecting pipes, and the lower part of the pressing rod is rotatably connected to the collar. The collar facilitates guiding the rotation of the pressing rod.

[0011] Preferably, the pressing rod includes a rod body and a rotating shaft. The rotating shaft is fixedly connected to the lower end of the rod body and is rotatably mounted within a collar. Pulling the rod body downward causes it to press the filter element down, using the downward force of the rod body to press the filter element into the housing, facilitating the pressing down of the filter element.

[0012] Preferably, the pressing rod further includes a pressure plate, the lower end of which is fixedly connected to the upper end of the rod body. The pressure plate increases the contact area between the rod and the hand.

[0013] Preferably, the filter element includes a frame, a sealing ring, and a filter screen. The sealing ring is fixedly connected to the opening of the frame, and the filter screen is fixedly connected to the inside of the frame. The frame is inserted into the housing, the sealing ring seals the gap between the housing and the frame, and the filter screen blocks particles, reducing the clogging rate.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. Connect the first pair of connecting pipes to the external pipeline by screwing through the first flange, and connect the second flange to the external pipeline by screwing through the second flange. Insert the filter element into the sealing shell, then pull down the pressing rod to press the pressing rod onto the filter element. Press the pressing rod down again to increase the downward pressure by levering the pressing rod, pressing the filter element down between the second pair of connecting pipes and the first pair of connecting pipes. The filter element filters solid impurities in the liquid or gas, preventing clogging. Insert another filter element into the sealing shell and press down in the same way to push the first one down. Repeat the same operation to push out the first filter element, causing a small amount of internal gas or liquid leakage. This facilitates filter element replacement and reduces the leakage rate during the replacement process, while ensuring safety.

[0016] 2. Insert the filter element into the guide groove, and then press the filter element into the housing so that the filter element is positioned between the first pair of connectors and the second pair of connectors, making it easier to guide the filter element between the first pair of connectors and the second pair of connectors.

[0017] 3. Use guide blocks to guide the filter element into the guide groove, and then guide it into the housing to facilitate docking of the filter element with the sealing housing.

[0018] 4. Pull the rod down to press the filter element down. Use the rod to increase the downward force and press the filter element into the housing. This makes it easier to press the filter element down.

[0019] 5. Insert the insert frame into the housing, seal the gap between the housing and the insert frame with the sealing ring, and use the filter screen to block particles and reduce the clogging rate. Attached Figure Description
