Problems solved by technology

[0002] When the pipeline chain plate conveyor transports flammable and explosive materials, its dust is easy to drill into the bearing chamber. Due to the dry friction heating of the bearing during continuous operation, the temperature of the bearing chamber rises (or due to static electricity), which often causes explosion accidents in the shaft chamber. , causing damage to the equipment and affecting the work of the entire conveying line, bringing economic losses to the enterprise, but also a serious safety hazard

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 Shown: an airtight mechanism for protecting the bearing chamber, including a bearing chamber 1, an air inlet 2 is opened on the housing of the bearing chamber 1, and the air inlet 2 is connected with a micro air inlet pump 4 through an air inlet pipe 3, and the gas The gas generated by the generator 5 is fed into the bearing chamber 1 with a small amount of gas through the micro-intake pump 4 to protect the bearing chamber 1 . Specifically, the gas generator 5 is a nitrogen generator, and the nitrogen gas generated by the gas generator 5 is input into the bearing chamber 1 through a micro air intake pump 4 to protect the bearing chamber 1 with a small amount of nitrogen; , or the air intake pipe 3 is directly inserted into the bearing chamber 1 through the air inlet 2 and the air inlet 2 is sealed.

Abstract

The invention discloses an airtight mechanism for protecting a bearing chamber. The airtight mechanism comprises the bearing chamber (1) and is characterized in that a gas inlet (2) is formed in a shell of the bearing chamber (1); the gas inlet (2) is connected with a minitype gas feeding pump (4) through a gas inlet pipe (3); gas generated by a gas generator (5) inputs trace gas into the bearing chamber (1) through the minitype gas feeding pump (4) so as to protect the bearing chamber (1). According to the invention, trace gas is inputted to the bearing chamber so as to protect the bearing chamber, so that the running of the bearing chamber is stable and the cost is low; the probability of blast accident of the bearing chamber is reduced; the structure is simple; the current equipment is conveniently modified, so that the airtight mechanism is fit for popularization and application.

Description

technical field [0001] The invention relates to the field of pipeline conveying devices, in particular to an airtight mechanism capable of protecting a bearing chamber when a pipeline chain conveyor conveys inflammable and explosive materials. Background technique [0002] When the pipeline chain plate conveyor transports flammable and explosive materials, its dust is easy to drill into the bearing chamber. Due to the dry friction heating of the bearing during continuous operation, the temperature of the bearing chamber rises (or due to static electricity), which often causes explosion accidents in the shaft chamber. , causing damage to the equipment, and affecting the work of the entire conveyor line, bringing economic losses to the enterprise, but also a serious safety hazard. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior art, and provide an airtight mechanism capable of protecting the bearing chambe...
