Description

Technical Field

[0001] The utility model relates to the technical field of cyclone flap valves, in particular to a cyclone double flap valve. Background Art

[0002] During the use of the preheater feed pipe, in order to prevent air leakage in the feed pipe and avoid internal temperature loss, an air lock valve is generally used for sealing. The air lock valve can be divided into a one-way air lock valve and a two-way air lock valve. The one-way air lock valve is also called a check valve. Its main function is to prevent backflow in the air duct and maintain a stable air volume at the air supply port. It only allows gas to flow in one direction. When the gas flow direction changes, the valve will automatically close. The two-way air lock valve is mainly used for equipment with high sealing performance requirements or long pipelines to maintain the sealing performance of the equipment and reduce energy consumption.

[0003] For flap valves, the general performance requirements are good opening and closing, the ability to withstand high-temperature materials and high-temperature gases, the ability to ensure no cross-flow and leakage, and the ability to withstand a certain degree of rigidity. The operation of flap valves has been related to whether the cement plant can operate normally. At the same time, flap valves have a huge impact on the coal consumption and electricity consumption of the firing system and the cost of cement. Saving energy is the development trend of all cement equipment under the background of environmental protection and the key to energy saving and consumption reduction. Improving the use effect of flap valves is the research direction of the cement industry.

[0004] Chinese utility model patent: Publication number CN218761445U, discloses a micro-motion double flap valve, including a flap valve body and a gear body, wherein a flap body is rotatably mounted inside the flap valve body through a hinge body, a limit frame is fixedly mounted in the middle of the lower surface of the flap body, and one end of the limit frame facing away from the flap body passes through the flap valve body, and the inner side of the limit frame on the outer side of the flap valve body is grooved and provided with a rack, and the rack is meshed and connected with the gear body.

[0005] In the existing technology, when CN218761445U is in use, a limit frame is set and the limit frame is fixedly connected to the flap body. At the same time, a rack is set on the limit frame. When the gear body rotates, the flap body is opened by meshing with the gear body and the rack. When in use, the gear body can be rotated by shaking the handle, thereby achieving the effect of opening the flap valve at a small angle.

[0006] However, in actual use, due to the device in the prior art, when conveying materials, the opening and closing end surfaces of the flap are impacted by the materials for a long time, which makes it very easy to wear, and then air leakage will occur due to wear. At the same time, the existing flap valve is difficult to monitor the air leakage, which makes it difficult to detect when air leakage occurs, thus affecting the material conveying efficiency. Therefore, a cyclone double flap valve is needed to solve the above problem. Utility Model Content

[0007] The purpose of the utility model is to provide a cyclone double flap valve, which has the advantages of reducing air leakage caused by wear and can provide feedback immediately when air leakage occurs, thereby facilitating maintenance, thereby solving the problem in the prior art that the device has a large degree of wear during use and is difficult to detect after air leakage occurs.

[0010] There are two pressure gauge bodies, and both pressure gauge bodies are electrically connected to the alarm mechanism body.

[0011] When using a cyclone double flap valve in the technical solution, the driving mechanism body is operated to rotate the arc-shaped rack, thereby realizing the flipping of the flap body, and after the flap body is flipped, the connecting joint can be used for material transportation. When used for a long time, the closed end of the flap body is severely worn, which will cause the air tightness of the connecting joint to decrease. At this time, since the limit block is made of soft rubber, the worn end of the flap body can be sealed by the limit block, thereby avoiding air leakage of the connecting joint. At the same time, when no material is conveyed, the air tightness can be monitored by a pressure gauge, and when air leakage occurs, the alarm mechanism body can be used to alarm, thereby reminding maintenance personnel to carry out timely maintenance.

[0013] The cross section of the connecting joint is designed with a rectangular structure, and flanges are fixedly installed at both ends of the connecting joint, so that the connecting joint can be connected and installed with the material conveying pipeline through the flange.

[0014] Preferably, the number of the reserved grooves is two, and a flap body is rotatably installed in the connecting section above the rear of the two reserved grooves.

[0015] The flap bodies are rotatably installed in the connecting joints slightly above the rear of the two reserved grooves, so that the connecting joints can be closed by the flap bodies.

[0016] Preferably, arc-shaped racks are fixedly mounted on the upper surfaces of the two flap bodies, and the ends of the two arc-shaped racks facing away from the flap bodies pass through the reserved holes respectively.

[0017] Arc racks are fixedly mounted on the upper surface of the flap body, and the ends of the two arc racks facing away from the flap body are passed through the reserved holes respectively, so that the arc racks can rotate, and when the arc racks rotate, the flap body can be driven to flip.

[0018] Preferably, a gear is installed on the driving mechanism body for transmission, and the gear on the driving mechanism body is meshed with the arc-shaped rack for transmission.

[0019] By installing a gear on the driving mechanism body and meshing the gear on the driving mechanism body with the arc-shaped rack for transmission, the flap body can be driven to flip in the connecting section through the driving mechanism body and the arc-shaped rack.

[0020] Preferably, the limit block is designed with a soft rubber material, the upper end surface of the limit block in the connecting joint is in contact with the flap body but not fixedly connected, a mounting plate is fixedly installed on the front of the limit block, and the mounting plate is fixedly installed on the front of the connecting joint by screws.

The driving mechanism body works to rotate the arc rack, thereby realizing the flipping of the flap body, and the connecting joint can be used for material transportation after the flap body is flipped. When used for a long time, the closed end of the flap body is seriously worn, which will cause the air tightness of the connecting joint to decrease. At this time, since the limit block is soft rubber, the worn end of the flap body can be sealed by the limit block, thereby avoiding air leakage of the connecting joint. At the same time, when material feeding is not carried out, the air tightness can be monitored by the pressure gauge, and when air leakage occurs, the alarm can be sounded by the alarm mechanism body, thereby reminding maintenance personnel to carry out timely maintenance, thereby achieving the effect of reducing air leakage caused by wear and providing feedback in the first time when air leakage occurs, thereby facilitating maintenance.
