Abstract

The utility model discloses an anti-blocking material-transferring pipeline, which comprises a pipe providing with a feeding opening and a discharge opening, a piston type pulling plate with an external connected pulling pole arranged in the inner cavity of the pipe, and matched with the inner wall of the pipe, and the piston type pulling plate can move at least from the feeding opening to the discharge opening, and the piston type pulling plate comprises a forward baffle and a backward single-direction flexible door. A shield cover is arranged outside of the pipe of the discharge opening and connected with the pipe. A limit guiding orbit is arranged on the end of the discharge opening to prevent the piston type pulling plate from getting away from the inner cavity of the pipe, and the orbit can easily solve the blocking of the transmission pipeline of mechanical device in the process of manufacture and transmission of material in the prior art. By pushing and pulling the piston type pulling plate in the inner cavity, the blocked material in the inner cavity of the pipe is cleaned, which is favorable for normal and effective progress of production.

Description

A kind of anti-blocking feeding pipe

Technical field

The utility model relates to a kind of material conveying pipe, specifically a kind of anti-blocking conveyance conduit that carries out mass transport in the chemical mechanical equipment that is applied in.

Background technique

In chemical process; the material of the vapour-liquid state that material that some viscosity are higher or solid content are higher; in the production course of conveying of material, cause the delivery line of chemical mechanical equipment to stop up through regular meeting; such as in the cracking processing procedure of junked tire; the material characteristic of being carried in the pipeline is similar to the just easy especially blocking pipeline of semifinished product of pitch; like this, gently then need to stop and overhaul mediation, heavy then can cause the generation of security incidents such as exploding.And present type of production enterprise; in actual production process, generally there is not any good especially way when running into this type of problem, can take the countermeasure of parking maintenance mediation usually; its consequence be produce normally be subjected to destruction in order, also influenced production and working efficiency simultaneously.

The model utility content

Technical problem to be solved in the utility model is to overcome above shortcomings in the prior art, provide a kind of and can guarantee that the carrier pipe road is unobstructed, do not influence manufacturing schedule, do not need the block-resistant type material conveyance conduit of parking maintenance, foregoing invention purpose of the present utility model can be achieved by the following technical programs.

A kind of anti-blocking feeding pipe, comprise the body that has material entrance and discharge port on it, be provided with one in the tube cavity space and match with inboard wall of tube body and to merge the piston type arm-tie that is circumscribed with pull bar, the length of the pull bar that is connecting on this piston type arm-tie at least can be from the material entrance end to discharge port end.

Described piston type arm-tie is made of the baffle plate of front end and the check valve of rear end.

Further, outside the discharge port end body, be provided with the protective housing that links to each other with body.

Also further, be provided with the limit guide rail that prevents piston type arm-tie disengaging tube cavity space at discharge port end.

Further, described piston type arm-tie adopts pneumatic control or induction control.

Adopt the anti-blocking feeding pipe of this technological scheme design, can solve the obstruction of chemical mechanical equipment delivery line in the production course of conveying of material in the prior art easily, cleaning by the piston type arm-tie is piled up material in the push pull maneuver of tube cavity realizes tube wall helps carrying out normally and efficiently of activity in production.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model being done one describes in detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is for adopting the user mode figure and the flow direction of material figure of pipeline described in the utility model;

Fig. 3 is the structural representation of piston type arm-tie described in the utility model.

Among the figure: 1, body 11, material entrance 12, discharge port 13, protective housing 14, limit guide rail 2, piston type arm-tie 21, baffle plate 22, valve 3, pull bar

Embodiment

A kind of anti-blocking feeding pipe as depicted in figs. 1 and 2, on the body 1 of pipeline, have material entrance 11 and discharge port 12, being provided with one at body 1 intracavity space matches with body 1 inwall and to merge the piston type arm-tie 2 be circumscribed with pull bar 3, the length of the pull bar 3 that is connecting on this piston type arm-tie 2 can have enough working spaces material that the pipeline inner product is stifled to discharge to guarantee piston type arm-tie 2 from material entrance 11 ends to discharge port 12 ends at least.

With the mass transport in the cracking processing procedure of junked tire is example, material is after pyrolysis furnace output, through material entrance 11, enter feeding pipe, again through discharge port 12, enter the absorption tower, enter next treating process, because the middle material characteristic of being carried is similar to pitch, so as easy as rolling off a log obstruction that causes pipeline, the way of handling if take to stop, then the Xiang Guan treating process of road up and down all can be involved, thereby influences the whole production process, adopts the described anti-blocking feeding pipe of this model utility, can effectively avoid this problem, can in case find that flow reduces to some extent in the pipe, start the cylinder that pull bar connects by inboard wall of tube body position of sound production detect probe in mass transport by predefined control program, control the operation that promotes piston type arm-tie 2 by the work of cylinder, the material of piling up in the pipeline is advanced in the absorption tower of discharge port one side connection.

Piston type arm-tie 2 as shown in Figure 3; and in conjunction with Fig. 1 and Fig. 2 explanation; piston type arm-tie 2 mainly is made of the baffle plate 21 of front end and the valve 22 of rear end; since be provided with can folk prescription to the valve 22 that passes through; and in the middle of preceding end-stopping plate 21, have the perforate that can supply material to pass through; so piston type arm-tie 2 is when operation work; but the gas-liquid in the pipeline is proper flow still; and the solid material of body 1 wall is released by piston; piston is released about 20 millimeters of pipeline; the set protective housing 13 that links to each other with body 1 in body 1 discharge port 12 end tops at this time; can effectively protect piston; and the spray liquid that can stop the top, absorption tower to fall enters the pipeline at piston rear portion; discharge port 12 places below protective housing 13 simultaneously; be provided with two and prevent that the piston type arm-tie breaks away from the limit guide rail 14 in tube cavity space, described limit guide rail 14 can make the Returning pipe inside that piston can be freely.

Certainly the control of piston type arm-tie 2 and pull bar 3 also can be according to actual needs by pneumatic control even manually control, and its frequency of okperation also can be provided with flexibly in conjunction with needs.

This anti-blocking feeding pipe, by in common pipe, introducing the design of the piston type arm-tie of an external control pull rod, thereby parking unnecessary in chemical process and maintenance mediation work have been save dexterously, and under the prerequisite that realizes the pipeline choke preventing function, do not influence the material transmission reliable, proceed, thereby obviously improved manufacturing efficiency, reduce the occurrence probability of security incident, made production work more orderly, smooth and easy.
