Description

Technical Field

[0001] This utility model relates to the field of boiler filtration protection technology, and in particular to a safety protection device for thermal oil boiler equipment. Background Technology

[0002] During the operation of a thermal oil boiler system, high-temperature environments and localized overheating can cause the thermal oil to undergo cracking and polymerization reactions, generating insoluble polymers and coke particles. These impurities are suspended in the oil and are prone to depositing at the bottom of the boiler drum, causing bulging and deformation, or adhering to the inner wall of the pipes, leading to a decrease in heat transfer efficiency or even pipe rupture accidents.

[0003] Existing filter cartridge cleaning methods mostly rely on backwashing, which makes it difficult to completely remove highly adhesive carbonized deposits, and filter clogging still occurs after long-term use.

[0004] Therefore, we propose a safety protection device for thermal oil boiler equipment to solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a safety protection device for thermal oil boiler equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for a thermal oil boiler, comprising a chamber, a lifting assembly, a driving assembly, a filter cartridge, and an active sealing ring. The lower end of the chamber is provided with a lower chamber, and the upper end of the chamber is provided with an upper chamber. A drain port is provided on the lower chamber, and a lower plate is provided on the drain port. An upper plate is provided on the upper chamber. The filter cartridge is located in the chamber and rotatably disposed between the upper plate and the lower plate. A driven sealing ring is provided on the outer wall of the filter cartridge. The active sealing ring is disposed between the inclined inner wall of the chamber and the inclined surface of the driven sealing ring, and the three are wedge-shaped and fit together to form a seal.

[0007] The drive component is used to drive the filter cartridge to rotate, and the lifting component is used to control the active sealing ring to lift and lower, so as to control the active sealing ring to move away from or close to the driven sealing ring.

[0008] Preferably, the drive assembly consists of a motor, a driven shaft, a drive wheel, a bearing, and a shaft protrusion. The driven shaft is rotatably mounted on the upper plate via a sealed bearing, and the bottom end of the driven shaft is located on the upper surface of the filter cartridge.

[0009] Preferably, the motor is mounted on the upper plate, the drive wheel is mounted on the output end of the motor, and the drive wheel meshes with the driven shaft gear.

[0010] Preferably, the bearing seat is disposed on the lower plate, the axle is disposed on the lower surface of the filter cartridge, and the axle is rotatably inserted into the bearing seat.

[0011] Preferably, the lifting assembly consists of a screw seat, a pull rod, and a ring block. The screw seat is rotatably mounted on the upper surface of the upper plate, the top end of the pull rod is threaded into the screw seat, the upper end of the pull rod passes through the upper chamber and the upper plate, and a sealing gasket is provided at the sliding connection position of the upper chamber and the pull rod.

[0012] Preferably, the ring block is located at the bottom end of the pull rod, and the active sealing ring is located on the lower surface of the ring block.

[0013] Preferably, the lower chamber has an inlet and the upper chamber has an outlet.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] During use, the safety protection device for thermal oil boiler equipment of this utility model can be installed on the circulating oil pipeline of the thermal oil boiler equipment through the inlet and outlet. The oil is filtered by the device during the circulation process, removing impurities and reducing potential hazards.

[0016] During the oil filtration process of this device, the oil enters the lower chamber and is filtered at the lower end of the filter cartridge before entering the filter cartridge. The filtered oil then enters the upper chamber through the upper end of the filter cartridge and finally re-enters the circulating oil pipeline through the outlet. During this process, the wedge-shaped fit between the active sealing ring, the passive sealing ring, and the chamber ensures that unfiltered oil cannot enter the chamber.

[0017] Multiple units can be connected in parallel on the circulating oil pipeline. After a period of use, the inlet and outlet of a single unit can be disconnected, and the heat transfer oil can flow through other units for filtration. Then, the drive assembly will work, and the motor will drive the drive wheel to rotate. Under the meshing action of the wheel teeth, the filter cartridge will rotate. Under the action of centrifugal force, the impurities attached to the lower outer wall of the filter cartridge will be thrown off. During this process, the lifting assembly can be operated and the screw seat rotated. Under the principle of the screw, the pull rod will drive the drive sealing ring to move downward away from the driven sealing ring and the chamber, thereby avoiding wear between the drive sealing ring and the driven sealing ring. Then, the lower plate can be removed, and the waste liquid inside the chamber can flow out, thus completing the cleaning operation of the filter cartridge.

[0018] In this invention, the filter cartridge has a built-in drive assembly that enables the filter cartridge to rotate at high speed. Centrifugal force is used to radially detach the coke particles attached to the outer wall of the filter cartridge, which is more suitable for removing viscous impurities than the traditional backwashing method.

[0019] The active sealing ring and the driven sealing ring form a conical pressure seal during operation, ensuring that unfiltered oil cannot short-circuit into the filtered side through the chamber gap. At the same time, the screw lifting mechanism enables the sealing ring to be quickly separated during cleaning, avoiding mechanical wear during the rotation cleaning process.

[0031] like Figures 1-4 As shown, the present invention proposes a safety protection device for a thermal oil boiler. Compared with Embodiment 1, this embodiment further includes: multiple devices can be connected in parallel on the circulating oil pipeline. After a period of use of a single device, the oil inlet and outlet of that device are disconnected, and the thermal oil flows through other devices for filtration.
