Description

Technical Field

[0001] This utility model relates to the field of biomass fuel processing technology, and in particular to a sealing device for a bearing seat of a biomass fuel crusher. Background Technology

[0002] Biomass fuels refer to solid, liquid, or gaseous fuels composed of or extracted from biomass. They represent an important direction for the development and utilization of renewable energy. In the field of biomass fuel processing, crushers are one of the key pieces of equipment.

[0003] Traditional biomass fuel crusher bearing housing sealing structures have many problems. For example, during crusher operation, due to the particle characteristics of biomass fuel and the severe vibration generated during crushing, the bearing housing is easily invaded by materials.

[0004] Existing sealing methods often employ only simple oil seal structures, which are difficult to withstand long-term high-intensity working environments. During the crushing process, material is scattered and squeezed onto the non-drive end bearing housing, often resulting in severe material accumulation at the bearing housing. Prolonged friction between the material and the rotating cutter shaft can easily cause fires, damaging the equipment. Once the material enters the bearing housing, it will lead to accelerated bearing wear, not only reducing the bearing's service life but also affecting the overall operational stability of the crusher, increasing the frequency and cost of equipment maintenance, and reducing production efficiency. Therefore, we propose a bearing housing sealing device for biomass fuel crushers. Utility Model Content

[0005] This utility model is a sealing device for the bearing seat of a biomass fuel crusher, proposed to overcome the shortcomings of the existing technology.

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

[0007] A sealing device for a biomass fuel crusher bearing seat includes a crusher bearing seat, with skeleton oil seals fitted on both sides of the crusher bearing seat. A hopper plate is provided on the outer side of the crusher bearing seat and near the skeleton oil seals. A crusher bearing seat sealing assembly is provided on the outer side of the crusher bearing seat and near the hopper plate. A connecting ring is provided on the outer side of the crusher bearing seat, and a crushing blade is provided on one side of the connecting ring.

[0008] Preferably, the crusher bearing housing sealing assembly includes an installation ring and a guide ring, which are respectively disposed on both sides of the hopper plate. A sealing ring is provided on one side of the guide ring, and a buffer assembly is provided between the installation ring and the guide ring.

[0009] Preferably, the buffer assembly includes a plug groove located on the outside of the mounting ring, the plug block being inserted into the plug groove, one side of the plug block being connected to one side of the guide ring, and the other side of the plug block being provided with a rubber block.

[0010] Preferably, there is a certain margin between the plug block and the plug slot.

[0011] Preferably, one side of the sealing ring is provided with several fixing holes 1, and one side of the mounting ring is provided with several fixing holes 2, and fixing components are provided in both fixing holes 1 and fixing holes 2.

[0012] In summary, this utility model has the following beneficial effects:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1-5 As shown, a sealing device for a biomass fuel crusher bearing seat involves fitting two skeleton oil seals 2 onto both sides of the crusher bearing seat 1. During the fitting process, it is important to ensure that the oil seals are installed flat to avoid scratching or twisting the oil seal lips. Appropriate tools can be used to assist in the installation, such as gently tapping with a rubber mallet to ensure that the oil seals fit tightly against the bearing seat, thus providing a preliminary sealing effect and preventing materials from entering the bearing from both sides of the bearing seat.

[0024] Install the hopper plate 3 on the outside of the crusher bearing seat 1 near the skeleton oil seal 2. Fix it by welding or bolting to ensure that the hopper plate is firmly installed. Its position and angle must meet the design requirements to provide basic support for the subsequent installation of sealing components. At the same time, ensure the sealing between the hopper plate and the bearing seat to prevent material from leaking into the vicinity of the sealing device and affecting its normal operation.

[0025] The installation of the crusher bearing housing sealing assembly 4 is a critical step. First, install the mounting ring 41 on one side of the hopper plate 3. It can be fixed with bolts to ensure that the mounting ring fits tightly with the hopper plate. The fixing bolts should be tightened to prevent loosening.

[0026] Next, install a sealing ring 43 on one side of the guide ring 42, align the fixing hole 44 of the sealing ring 43 with the fixing hole 45 of the mounting ring 41, and use fasteners such as bolts and nuts to fix the sealing ring between the mounting ring and the guide ring, ensuring that the sealing ring is installed flat and seals well, preventing material from entering the bearing housing from the gaps in the sealing assembly.

[0027] A insertion groove 46 is provided on the outer side of the mounting ring 41. The insertion block 47 on one side of the guide ring 42 is inserted into the insertion groove 46. Since there is a certain amount of clearance between the insertion block 47 and the insertion groove 46, care should be taken to adjust the position of the guide ring during insertion to ensure that its relative position with the mounting ring is accurate, thus ensuring the normal operation of the buffer assembly. At the same time, the rubber block 48 provided on the other side of the insertion block 47 can play a buffering role during equipment operation, reducing the impact of vibration or other external forces on the sealing assembly, and improving the stability and service life of the sealing assembly.

[0028] Install the connecting ring 5 on the outside of the crusher bearing housing 1, and use appropriate connection methods such as welding or key connection to ensure a firm and reliable connection and to ensure its coaxiality with the bearing housing, so as to reduce the unbalanced force during equipment operation.

[0029] Install the crushing blade 6 on one side of the connecting ring 5. Secure the crushing blade to the connecting ring with bolts or other reliable connection methods to ensure that the crushing blade is firmly installed and that the cutting edge angle and position meet the design requirements so that the crusher can effectively crush biomass fuel when it is working. At the same time, care should be taken to avoid damage to the equipment or affect the normal operation of the sealing device due to improper installation that may cause the blade to loosen.

[0030] After completing the installation of all the above components, conduct a comprehensive inspection of the entire biomass fuel crusher bearing housing sealing device. Check whether the connections of each component are secure, whether the seals are good, and whether there are any loose, deformed, or damaged parts.

[0031] Perform no-load testing, start the crusher, observe the equipment operation, and check the bearing housing sealing device for abnormal vibration, noise, or leakage. If any problems are found, stop the machine immediately to investigate the cause and make adjustments and repairs to ensure that the sealing device can work effectively under normal operating conditions, meet the sealing requirements in the biomass fuel crushing process, extend the service life of the equipment, and improve the reliability and stability of the equipment.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
