Abstract

The invention relates to a discharge port anti-abrasion device of grain conveying and cleaning equipment, wherein grains are conveyed to a grain inlet area from an inlet chute, a part of grains do not flow when reaching a storage section I and a storage section II, after the grains in the storage section are fully accumulated, the rest of grains are conveyed to an outlet flange along a grain flow area, the flowing grains rub against the previously accumulated grains and cannot directly rub against a pipe wall, and the abrasion to the pipe wall is greatly reduced. Similarly, the flowing grains are only rubbed with the grains accumulated at the bottom when the grains are transferred from the inlet section II to the outlet section, and the grains cannot directly impact and rub a bottom steel plate or a wear-resistant material like before improvement, so that the service life of the discharge hole is prolonged.

Description

Technical Field

The invention relates to the field of grain processing equipment, in particular to an anti-abrasion device for a discharge port of grain conveying and cleaning equipment.

Background

In many industrial places, solid materials such as grains need to be conveyed by pipelines, grains are conveyed and cleaned at turning positions of outlets of equipment, the grains intensively impact and rub pipe walls (such as a rubbing area 11 in a figure 1) which are easy to abrade, the main method before improvement is to increase the hardness and thickness of materials at abraded parts in a limited way, but the abrasion problem cannot be solved fundamentally, the service time is short, the rubbing pipe walls need to be replaced frequently, and the device is mostly used at high altitude, and is high in replacement difficulty and high in danger.

including the import flange, the import flange is connected with import section I, and import section I is connected with import section II, and in import section II top stretched into import section I, and be equipped with between import section II and the import section I and store festival I, be equipped with the C-shaped groove between import section II and the export section, this C-shaped groove personally submits the acute angle with the level, is equipped with between export section and the import section II bottom and stores festival II, exports the section and exports flange joint.

Further, the sections of the storage section I and the storage section II are both right-angled trapezoids.

Further, the inlet section I, the inlet section II and the outlet section are integrally formed.

Further, the inlet flange is connected with an inlet chute.

Further, the section of the inlet section I is rectangular.

Further, the inlet section II is cylindrical.

Further, the section of the outlet section is square.

The invention has the beneficial effects that: the invention relates to a wear-proof device for a discharge port of grain conveying and cleaning equipment, which is characterized in that a storage section I is arranged between an inlet section I and an outlet section II, a storage section II is arranged between the inlet section II and the outlet section, and a storage section is arranged at a grain turning impact friction part.

Detailed Description

As shown in fig. 1 and fig. 2, before improvement, an inlet flange 1 is connected with an inlet chute 12, the inlet flange is connected with an outlet section 4 through an inlet section II3, the outlet section is connected with an outlet flange 5, and because the inlet section II and one side of the outlet section are inclined downwards, grains rub against the inner wall of the pipe (namely a friction area 11) at a discharge port, and further wear is generated. Taking corn conveying as an example, the production is carried out for 24 hours continuously, and the discharge port device needs to be replaced once in 1-2 months due to the fact that the corn is directly and strongly impacted and rubbed with the pipe wall.

As shown in fig. 3 to 7, the present invention is an anti-wear device for a discharge port of grain conveying and cleaning equipment, an inlet flange is connected with an inlet section I2, the inlet section I is connected with an inlet section II3, the top of the inlet section II extends into the inlet section I, a storage section I7 is arranged between the inlet section II and the inlet section I, the storage sections I are respectively arranged at two sides of the inlet section II, the sections of the storage sections I and II are both right trapezoid, and no-flow grains 10 are stored inside the storage sections I and II; the inlet section II is cylindrical, the top of the inlet section II is communicated with the inlet section I, and the bottom of the inlet section II is closed. The section between the inlet flange and the top of the inlet section II is an isosceles trapezoid. Cereal is carried from the import flange, piles up when flowing into storage section I of import section I, and after piling up in the storage section I, remaining cereal flows into cereal flow area 8 along isosceles trapezoid district.

A C-shaped groove opening is formed between the inlet section II and the outlet section, an acute angle is formed between the C-shaped groove and the horizontal plane, a storage section II6 is arranged between the outlet section and the bottom of the inlet section II, and after the grains are fully accumulated in the storage section II, the rest grains directly flow into a grain moving area to the outlet flange. The section of the inlet section I is rectangular, the section of the outlet section is square, and the outlet section is connected with an outlet flange 5. The inlet section I, the inlet section II and the outlet section can be designed to be integrally formed, and replacement and disassembly are convenient.

Cereal is carried to cereal import district 9 from the import elephant trunk, and some cereal just no longer flows when arriving storage section I and storage section II, waits to store in the section cereal and piles up the back full, and remaining cereal flows the district 8 along cereal and carries to the outlet flange, and the cereal that flows produces the friction with accumulational cereal before, can directly not rub with the pipe wall, has alleviateed the wearing and tearing to the pipe wall greatly. Similarly, the flowing grains are only rubbed with the grains accumulated at the bottom when the grains are transferred from the inlet section II to the outlet section, and the grains cannot directly impact and rub a bottom steel plate or a wear-resistant material like before improvement, so that the service life of the discharge hole is prolonged.

Taking corn conveying as an example, after improvement, the flowing corn does not directly generate impact friction with the pipe wall, but generates friction with the accumulated corn, and the service life of the device is prolonged. Under the same condition, the material is replaced once in 10-20 months, and the service life is prolonged by about 10 times, so that the problem that the discharge port is not wear-resistant is fundamentally solved.

In light of the foregoing description of preferred embodiments according to the invention, many modifications and variations can be made by the worker skilled in the art without departing from the scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
