Description

Anti-clamping roller mechanism of desulfurization vacuum belt conveyor Technical Field The utility model relates to the technical field of optimization of limestone-gypsum wet desulfurization equipment, in particular to an anti-sticking roller mechanism of a desulfurization vacuum belt conveyor. Background The desulfurization vacuum belt conveyor is key equipment in a limestone-gypsum wet desulfurization equipment system, plays a quite important role in the whole gypsum dehydration system, and has the main effects that gypsum cyclone underflow slurry with the solid content of about 50% is dehydrated and becomes gypsum with the surface water content of less than 10% for comprehensive utilization, but due to reasons of design, equipment selection, installation process and the like, the failure rate is high, the normal operation of desulfurization facilities is seriously threatened, and once the failure cannot be timely eliminated, the environment-friendly supergrid unit is extremely easy to stop. Because the vacuum belt conveyor has poor working environment, complex system, corrosive medium and higher failure rate, aiming at the active equipment, how to reduce the failure rate of the equipment is still the key point of equipment maintenance. Wherein, because the slurry has larger particle content and fine particles, the situation of power roller clamping is often generated after the desulfurization vacuum belt conveyor is used for a long time. And when the device is used and is placed for a period of time to restart, the slurry flowing into the position of the power roller bearing is dried, and the problem of adhesion of the power roller bearing is caused because of the high viscosity of the slurry, so that a power system needs to bear a high load in the starting stage of the power roller, and the adhesion of the power roller is relieved. Disclosure of utility model The utility model aims to provide an anti-blocking roller mechanism of a desulfurization vacuum belt conveyor, which solves the problems that the existing belt conveyor is easy to cause blocking rollers due to high viscosity of slurry, and a power roller is easy to be stuck after the belt conveyor is stopped for a long time. In order to solve the problems, the utility model adopts the following technical means: The utility model provides a desulfurization vacuum belt feeder anti-sticking roller mechanism, includes the belt roller, the both sides coaxial arrangement of belt roller has the reference column, one reference column and power unit coaxial coupling, the reference column rotates to be installed on the support frame, be used for the reference column passes hold the clearance on the support frame, the reference column the outer wall with hold through the bearing connection between the inner wall in clearance, the bearing is located hold in the clearance, hold the clearance inner wall with it has the shutoff chamber to construct between the reference column outer wall, be constructed with shutoff medium conveying mechanism in the support frame, shutoff medium conveying mechanism's discharge end with shutoff chamber intercommunication. Preferably, the plugging medium conveying mechanism comprises a collecting cavity arranged in the supporting frame, a liquid outlet channel which is used for communicating the collecting cavity with the plugging cavity is formed in the supporting frame, the liquid outlet channel is used as the discharging end, an infusion channel is further arranged in the supporting frame, the infusion channel is communicated with the collecting cavity and the outside, and a liquid inlet end of the infusion channel is communicated with the pressure maintaining water supply mechanism. Further, the collecting cavity is coaxially arranged with the positioning column, the collecting cavity is an annular cavity, and the liquid outlet channel is arranged around the axis of the collecting cavity.
