Description
Technical Field
The invention relates to the technical field of air seal machinery, in particular to a positive pressure air seal machinery with an anti-blocking function.
Background
The air seal machine is an important device in a pneumatic conveying and ventilating dust removing network, has the main functions of continuously and timely discharging materials in a discharger or a dust remover and simultaneously preventing external air from entering the discharger or the dust remover, is widely suitable for pneumatic conveying of industrial devices such as rice milling, powder making, feed, machinery, chemical industry, medicine, tobacco, metallurgy, cement, dust removal and the like and discharging of pipe network pressure states, and plays a role in continuously discharging powdery, granular, flaky and fibrous materials in positive pressure and negative pressure states.
The existing air seal machinery is generally composed of a rotating shaft, a driving mechanism for driving the rotating shaft to rotate, blades connected to the rotating shaft and an air seal machinery shell, wherein a feeding hole and a discharging hole are further connected to the air seal machinery shell, in the using process, materials enter a groove body formed by the blades in the air seal machinery through the feeding hole, and the materials entering the air seal machinery are discharged by driving the rotating shaft to rotate through the driving mechanism.
Because there is the clearance between the casing of blade and air seal machinery shell in the air seal machinery, need set up the clearance less usually, when the flow is uneven in the use, the material can enter into the clearance department between blade and the air seal machinery shell through the drive of blade, extrude very easily after inseparable and cause the jam, can cause the damage of air seal machinery blade even, seriously influence normal production, must overhaul or change the blade, will delay a large amount of operating time in the process of dismantling the change to air seal machinery, the work efficiency has seriously been reduced.
Disclosure of Invention
The air seal machinery with the anti-blocking function is provided, the air seal machinery has the function of automatically adjusting the gap between the blade and the air seal machinery shell in the using process, automatic adjustment can be carried out when the blade and the air seal machinery shell are blocked, the equipment can not be maintained in a large amount of time, and the working efficiency is high.
In order to achieve the purpose, the invention provides a positive pressure air seal machinery with an anti-blocking function, which comprises an air seal machinery shell, a feeding hole and a discharging hole which are connected to the air seal machinery shell, a rotating shaft connected to the inside of the air seal machinery shell, blades connected to the rotating shaft and a driving mechanism for driving the rotating shaft to rotate, wherein a plurality of arc-shaped movable plates are connected between the inside of the air seal machinery shell and the blades through a telescopic mechanism, the arc-shaped movable plates are mutually matched and spliced to form an inner cavity of the air seal machinery, and a pressure sensor electrically connected with the telescopic mechanism is connected to the arc-shaped movable plates.
The working principle and the process of the technical scheme are as follows: when the positive pressure air seal machine with the anti-blocking function is used, materials are put into the groove body formed by the blades from the feeding hole and enter the groove body, then the groove body filled with the materials is rotated to the discharging hole through rotation of the rotating shaft, the quantitative discharging function can be realized, the materials can enter the gap between the blades and the air seal machine shell in the process that the materials enter the groove body formed by the blades and rotate, the locking condition can be caused when the materials are accumulated more, at the moment, the blades can be damaged if the materials continue to rotate, the gap between the blades and the air seal machine shell must exist, otherwise, the blades cannot rotate, therefore, the air seal machine is provided with the movable plate between the blades and the air seal machine shell, the gap between the blades and the movable plate is equivalent to the gap between the blades and the air seal machine shell in the traditional air seal machine, when the materials enter the gap between the blades and the arc-shaped movable plate and are blocked, the material that is blocked will cause certain pressure to the arc fly leaf, can feel the telescopic machanism for connecting on the arc fly leaf with the signal transmission after pressure is experienced to the pressure sensor who connects on the arc fly leaf, telescopic machanism shortens to be close to the air seal machinery shell after receiving the signal, the distance of the clearance between blade and the arc fly leaf has been increased promptly, make the material of card between blade and arc fly leaf not hard up whereabouts, can continue to drive the pivot rotation and produce, after recovering normal production, can not perceive pressure on the pressure sensor, pressure sensor will not have the signal transmission of pressure for telescopic machanism this moment, telescopic machanism extension, make the arc fly leaf resume original position can. Wherein the movable distance of the arc-shaped movable plate is 2-4 mm.
Compared with the traditional air seal machinery, the air seal machinery in the application has the advantages that the arc-shaped movable plates are connected inside the air seal machinery shell, the arc-shaped movable plates are matched with each other and are spliced into the internal shape of the air seal machinery shell, but the distance between the arc-shaped movable plates and the blades can be adjusted, and under the condition that materials enter the space between the movable plates and the blades to cause blockage, the distance between the movable plates and the blades can be increased through the movement of the arc-shaped movable plates to prevent the blockage; meanwhile, the pressure sensor is connected to the movable plate, when materials are clamped between the movable plate and the blades, sensing signals are transmitted to the telescopic mechanism through the pressure sensor, the telescopic mechanism is enabled to adjust the movable plate, operation is further enabled to be more convenient, the arc-shaped movable plate is moved as soon as possible before locking, the anti-blocking function is enabled to be more automatic, shutdown repair is avoided, continuous production is achieved, damage to the blades of the air seal machinery is greatly reduced, maintenance cost is reduced, time for manually repairing the air seal machinery is shortened, and production efficiency is improved.
