Description

Durable anti-blocking suction pipe Technical Field The utility model relates to the technical field of negative pressure conveying, in particular to a durable anti-blocking suction pipe. Background With the development of the carbon industry, in the process of roasting the carbon blocks, the heat preservation materials are cleaned and covered with the existing conventional crown block which is manually upgraded into a suction and discharge crown block for automatic operation. The material suction pipe is a core component for realizing automatic conveying of powdery and granular materials. However, the material properties of the carbon industry present a serious challenge to the suction tube. On the one hand, the powdery or granular material has high hardness, and can continuously generate strong friction and impact on the inner wall of the suction pipe in the negative pressure conveying process, so that abrasion is increased, the flow speed and the direction of the material are changed rapidly, the local abrasion is more serious due to factors such as high temperature, the service life of the suction pipe is greatly shortened, the maintenance cost is increased due to frequent replacement, and the production progress is influenced. On the other hand, the blockage problem easily occurs in the suction pipe, the granularity difference of the materials is relatively large in carbon production, partial large-particle materials fall down due to the loss of power in the rising process, the blockage phenomenon easily occurs at the bent and diameter-changing positions of the suction pipe, the conveying interruption is caused, and more serious, the long-time blockage can possibly cause equipment overload, damage matched conveying equipment such as fans, vacuum pumps and the like, and potential safety hazards exist. Disclosure of utility model The utility model provides a durable anti-blocking suction pipe, which aims to solve the technical problems in the prior art. In order to solve the problems, the durable anti-blocking suction pipe adopts the following technical scheme that the durable anti-blocking suction pipe comprises a suction pipe inner pipe, a suction pipe inner pipe and a suction pipe outer pipe, wherein the suction pipe inner pipe is used for conveying materials, and an anti-blocking structure for preventing materials from accumulating is arranged at the top outlet of the suction pipe inner pipe; the outer tube of the suction pipe is connected above the inner tube of the suction pipe; The square rounding connecting pipe is used for providing a larger space for materials, reducing the airflow speed and further reducing the scouring of the materials to the wear-resistant elbow, and is arranged above the outer pipe of the suction pipe and connected with the outer pipe of the suction pipe; The ball joint is used for connecting the square rounding connecting pipe and the wear-resistant elbow, and is arranged on the square rounding connecting pipe and connected with the square rounding connecting pipe; and the wear-resistant elbow is arranged above the ball joint and is detachably connected with the ball joint so as to replace the wear-resistant elbow. By adopting the technical scheme, the problems of blockage and serious abrasion of the suction pipe are solved. The anti-blocking structure is arranged at the joint of the inner pipe of the suction pipe and the outer pipe of the suction pipe, if large-particle materials lose power in the rising process, the materials can fall along the anti-blocking structure to prevent the materials from piling up, small-particle materials are conveyed away by high-speed air flow to realize the anti-blocking function, the diameter of the square rounding connecting pipe is larger, the inner space of the square rounding connecting pipe is enlarged, the air flow speed is reduced, and the scouring of the materials to the ball joint or the wear-resistant elbow is further reduced, so that the effect of prolonging the service life is realized. The ball joint can realize local swing, and part of deflection does not influence the work in the material sucking and walking process, and the deformation of the components is avoided, and in addition, the ball joint reduces the airflow jerk to a certain extent. As a further improvement, the anti-blocking structure comprises an inner wall plate, a reinforcing plate and a sealing plate which are sequentially arranged from inside to outside, wherein the inner wall plate, the reinforcing plate and the sealing plate are sequentially staggered in height to form a step-shaped structure so as to prevent materials from accumulating. By adopting the technical scheme, the accumulation of materials is avoided. Wherein, the sealing plate adopts detachable connection, if the sealing plate is seriously worn, the sealing plate can be detached and replaced so as to recover the sealing effect As a further improvement, a gap is arranged between the sealing plate
