Summary of the invention
The purpose of this utility model becomes large deformation, even disrepair phenomenon and can not Timeliness coverage during the course in order to solve because aperture occurs vibration screen, the problem of doing over again is caused to powder production, a kind of reasonable in design is provided, sample at any time to going out powder in process of production, the qualified data of instant acquisition, have the oscillating sieving machine of auxiliary security sieve structure.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of oscillating sieving machine with auxiliary security sieve structure, it is characterized in that comprising the principal oscillation screen cloth being provided with powder delivery road under powder delivery road and main sieve on main sieve, principal oscillation screen bottom is provided with vibrating base, under described main sieve, powder delivery road is connected with sampling stria, sampling stria leads to the auxiliary sieve of safety be positioned at below principal oscillation screen cloth, the auxiliary sieve of described safety is provided with powder delivery road on auxiliary sieve, and on auxiliary sieve, powder delivery road leads to white catch tray.This programme is using the instant sampling observation facility of auxiliary for safety sieve as principal oscillation screen cloth output of products, under main sieve, powder delivery road arranges sampling stria, and identical with principal oscillation screen cloth for every technical performance design of auxiliary for safety sieve, become a micro-vibration sieve, at any time quality analysis is carried out to main product.
As preferably, the auxiliary sieve of described safety and vibrating base are fixed, and are provided with powder delivery road under the auxiliary sieve communicated with powder delivery road under main sieve in the auxiliary sieve of safety.The auxiliary sieve of safety is fixed with vibrating base and is obtained the vibration frequency identical with principal oscillation screen cloth.
As preferably, the auxiliary sieve of described safety is positioned at the below of powder delivery road matching part under principal oscillation screen cloth and main sieve, the screen cloth diameter of the screen cloth diameter≤1/6 principal oscillation screen cloth of the auxiliary sieve of safety.Needing in checking process, ensureing that sampling sample is reasonable, return powder delivery road under main sieve through the qualified products after the auxiliary sieve of safety.
As preferably, under described main sieve, powder delivery road comprises horizontal powder delivery road and vertical powder delivery road, and sampling stria is connected on horizontal powder delivery road, and under auxiliary sieve, powder delivery road communicates with vertical powder delivery road.Ensure that enough sample sizes and qualified products reflux smooth and easy.
As preferably, the auxiliary sieve of described safety is equal with principal oscillation screen cloth sieve number.Index for examination is identical with product index.
As preferably, described sampling stria is provided with gate.Carry out opening a sluice gate sampling needed for the reality such as the behaviour in service of principal oscillation screen cloth, the condition of production of product.
Effective effect of the present utility model is: by the auxiliary sieve of the safety on principal oscillation sieving machine, constantly or pointedly sampling screening is carried out to powder delivery product, effectively judge that whether production process is controlled, avoid substandard product to enter subsequent production and bring phenomenon of doing over again, sampling is rationally, greatly cost-saving.
