Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dehumidification and dust removal devices, and in particular relates to a device for removing high-temperature moisture and dust generated by a biomass pellet machine in the production of biomass pellets. Background Art
[0002] The production process of biomass pellets is the process of crushing and extruding wood. Heat is generated during the extrusion process. If the moisture is not well controlled, positive pressure will be generated in the pressure wheel chamber of the biomass pellet machine, causing moisture and dust around the pellet machine, affecting the production environment and production safety. What's more, dust enters the bearing chamber and causes damage to the main shaft. In order to solve this problem, many manufacturers use fans to directly extract moisture. The main problem caused by this is that the fan cannot withstand corrosion and wear. Usually, the fan blades will be worn through in about three months and need to be replaced. The fan motor will also burn out due to excessive moisture and unbalanced impellers. In this process, water vapor condenses and pollutes the production environment due to the use of negative pressure ventilation. Summary of the invention
[0003] The utility model aims to solve the problems existing in the prior art and to provide a device which can effectively remove high-temperature moisture and dust in the production of a biomass pellet machine and is not easily damaged.
[0004] The technical solution adopted by the utility model is as follows:
[0005] A device for removing high-temperature moisture and dust in the production of a biomass pellet machine comprises a dehumidification pipe connected to a pressure wheel chamber of the biomass pellet machine, a venturi tube connected to the outer end of the dehumidification pipe, a high-pressure fan connected to one end of the venturi tube, and a pulse-type cyclone bag dust collector connected to the other end of the venturi tube. The high-pressure fan sprays high pressure to the venturi tube to form a negative pressure in the venturi tube, so that the pressure wheel chamber of the biomass pellet machine becomes a negative pressure state, and the moisture and dust in the pressure wheel chamber are automatically extracted and sent to the pulse-type cyclone bag dust collector.
[0006] Furthermore, the high-pressure fan is a fan with a wind pressure not less than 30 kPa.
[0007] The utility model has a simple structure and reliable operation. It only needs to set up a dehumidification pipe, a venturi tube, a high-pressure fan and a pulse cyclone bag dust collector to form a negative pressure system that can extract air to the outside of the pressure roller chamber. The high-pressure air generated by the high-pressure fan can be used to extract and separate the dust and moisture in the pressure roller chamber to achieve the dehumidification and dust removal effect. Moisture and dust will not cause damage to the high-pressure fan, the device has low maintenance costs and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
