Description

Fastener for connecting piece of pneumatic conveying pipeline

Technical Field

The utility model relates to a firepower thermoelectric equipment technical field specifically is a pneumatic conveying pipeline connecting piece fastener.

Background

Pulverized coal pneumatic conveying system, powder material adopt the pneumatic conveying mode to carry, sneak into the foreign matter in the powder material, will cause the storehouse pump feeding not smooth, storehouse pump discharge gate is stifled, the foreign matter gets into and causes pneumatic conveying efficiency to reduce and take place frequent stifled pipe even in the pipeline, and current pipe connection spare fastener is not convenient for overhaul for simple connection, can not solve the problem of sneaking into the foreign matter in the powder.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a fastener for a connecting piece of a pneumatic conveying pipeline comprises a connecting pipe, wherein a filtering well is arranged in the middle of the connecting pipe, and a detachable filtering plate is arranged in the filtering well;

the filter includes the plate body that closely cooperates with the filter well internal surface, and the metal mesh has been installed to the internal surface of plate body, and the top fixedly connected with permanent magnet piece of plate body sets up the pipe connection spare fastener between pipeline and pipeline or between pipeline and air pump, can filter powder material foreign matter, and permanent magnet piece cooperation metal mesh class adsorbs metallics, avoids damaging the air pump, even if take place to block up, also is convenient for in time maintain.

Furthermore, a material collecting box communicated with the filter well is fixedly connected to the bottom of the connecting pipe at the position of the filter well, and a blanking notch is formed in the plate body close to the material collecting box;

the baffle has been pegged graft in the case that gathers materials, and after the air pump stop work, can pull open the baffle, strike the connecting pipe, be convenient for fall into the case that gathers materials with the foreign matter of metal mesh interception from the unloading breach in, need work once more, with the baffle reset, can, this operation can improve metal filters's life, avoids the foreign matter to block up the metal mesh.

Furthermore, the filter is a plurality of and the spacing inlays locates the spacing inslot of seting up in the filter shaft, reinforcing filter effect.

Furthermore, the top of the filter well is also screwed with a sealing cover, so that the air leakage at the top of the filter well is avoided, and the transportation efficiency is not influenced.

The working principle and the beneficial effects are as follows: through setting up the pipe connection spare fastener between pipeline and pipeline or between pipeline and air pump, can filter powder material foreign matter, and permanent magnet piece cooperation metal mesh adsorbs metallics on class, avoids damaging the air pump, even if take place to block up, also is convenient for in time maintain.

FIG. 1 is a schematic cross-sectional structure of the present invention;

fig. 2 is a schematic cross-sectional view of a-a in fig. 1 according to the present invention.

In the figure: 1. a connecting pipe; 2. a filter well; 3. a filter plate; 31. a plate body; 32. permanent magnet blocks; 33. a metal mesh; 4. a material collecting box; 5. a blanking gap; 6. a sealing cover; 7. and a baffle plate.

Detailed Description

The invention will be better understood from the following examples.

The drawings in the specification show the structure, ratio, size, etc. only for the purpose of matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and not for the purpose of limiting the present invention, so the present invention does not have the essential meaning in the art, and any structure modification, ratio relationship change or size adjustment should still fall within the scope covered by the technical content disclosed in the present invention without affecting the function and achievable purpose of the present invention. Meanwhile, the terms "upper", "lower", "front", "rear", "middle", and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

As shown in fig. 1-2, a fastener for a pneumatic conveying pipeline connector comprises a connecting pipe 1, wherein a filter well 2 is arranged in the middle of the connecting pipe 1, and a detachable filter plate 3 is arranged in the filter well 2;

the filter 3 includes the plate body 31 that closely cooperates with 2 internal surfaces of filter well, metal mesh 33 has been installed to the internal surface of plate body 31, the top fixedly connected with permanent magnet piece 32 of plate body 31 sets up the pipe connection spare fastener between pipeline and pipeline or between pipeline and air pump, can filter powder material foreign matter, and permanent magnet piece cooperation metal mesh class adsorbs metallics, avoids damaging the air pump, even if take place to block up, also be convenient for in time maintain.

Wherein, the bottom of the connecting pipe 1 is fixedly connected with a material collecting box 4 communicated with the filter well 2 at the position of the filter well 2, and a blanking gap 5 is arranged at the position of the plate body 31 close to the material collecting box 4;

the baffle 7 is inserted in the material collection box 4, after the air pump stops working, the baffle can be pulled open, the connecting pipe is knocked, the foreign matter intercepted by the metal mesh is convenient to fall into the material collection box from the blanking notch, the baffle needs to work again, and the baffle is reset, namely, the service life of the metal filter screen can be prolonged by the operation, and the metal mesh is prevented from being blocked by the foreign matter.

Wherein, the filter 3 is a plurality of and interval inlays the spacing inslot of seting up in the filter well 2, reinforcing filter effect.
