A sieve breakage detection device

Abstract

The invention discloses equipment for detecting damage of sieving pieces. The equipment comprises a body, wherein a material inlet is formed on the body; the body is internally provided with a sieve capable of vibrating; powder materials entering from the material inlet enter the sieve which is arranged in an inclined manner; a discharging port is formed at the low end of the sieve; a foreign-matter hopper for receiving foreign matters is arranged at the lower side of the discharging port, and is provided with a weighing device; when the weighing device detects that the weight is more than the set value, the sieving piece is damaged; a ball body is placed on a sieving mesh of the sieve; the sieve is provided with a blocking plate for blocking the ball body; a gap left between the blocking plate and the sieving mesh is used for passing of the power materials; the blocking plate is used for preventing the ball body from sliding out of the discharging port or blocking the discharging port; and a material outlet is formed on the body positioned at the lower side of the sieve. The equipment disclosed by the invention has the advantages that whether the sieving piece of a crusher is damaged can be automatically detected, large-particle materials are prevented from entering next procedure, the defect caused by artificial judgment is eliminated and the requirement for automatic control of a feed production factory also can be met simultaneously.

Description

technical field [0001] The patent of the invention relates to a sieve breakage detection technology of a pulverizer, in particular to a sieve breakage detection device, which belongs to the technical field of grain and feed processing machinery. Background technique [0002] Due to the influence of drying methods and transportation conditions in our country, the raw grain contains impurities such as stones and metal blocks; Under the impact of the impact, stones or metal blocks will break through the screen of the crusher and cause damage. [0003] Due to the breakage of the sieve of the pulverizer, in the subsequent material crushing process, some materials will not be hit by the hammer or fail to reach the required crushing fineness, and will leak directly from the damaged sieve; In the steps of mixing, conveying, conditioning, granulation, etc., under normal circumstances, the granulator can only get the information of the breakage of the pulverizer screen through visual...

Problems solved by technology

[0004] The working mode of the feed mill is to grind the ingredients first, and then the granulator starts to work when the "to-be-granulated bin" is filled to a certain degree of fullness. Usually, the granulator has been working for 1-2 hours at this time, and some A large number of materials have been batched and mixed and entered the "to-be-granulated bin". Once it is found that the material has not been crushed to meet the requirements, it is necessary to rework all the prepared materials and re-grind. This is a very heavy task, and It takes time, electricity, manpower, etc.
