Abstract

The utility model discloses a solid material flow monitoring device used for unpacked solid materials, comprising a material flow monitoring part and an automatic vibration bin. The material flow monitoring process is accomplished by a material measuring plate. When the materials flow is broken, the material measuring plate can automatically start a limit switch of the automatic vibration bin. Thus, the automatic vibration bin can ensure the continuous running of the material flow. The utility model has the advantages of simple device, reasonable structure, low cost and convenient maintenance. The solid material flow monitoring device is suitable for poor manufacturing environments of powder dust, high temperature, etc.

Description

Solid material flow monitoring device

The utility model is applicable to the feeder of bulk solid material, can monitor the materials flow operation of feeder.

Before the present utility model, the materials flow of feeder monitors and shakes the storehouse, generally by manually finishing, promptly manually monitors whether fracture of feeder, and when finding fracture, the start button in the manual operation vibrator circuit makes the vibrator energising, the vibrator vibration.After materials flow was normal, the manual operation stop button made the vibrator outage, stops vibration.This method has increased workman's nervous degree, Yi Fashengyin human negligence simultaneously and fracture phenomenon.In recent years, adopt the electro-optical tubes monitoring device, alleviated hand labor intensity, can monitor the feed situation automatically, but this equipment requires the working environment dust few, otherwise when dust covers photoelectric receiving arrangement, light source can't the start-up control system, and maintenance, cost of installation are higher.

For addressing the above problem, the utility model proposes a kind of survey flitch formula materials flow monitoring device, survey flitch be installed in materials flow the place ahead to, materials flow is lifted and is surveyed the flitch lower end, makes to survey the limit switch that the Vibration on Start-up device is left in the flitch upper end.When materials flow generation fracture, it is sagging automatically by deadweight to survey the flitch lower end, and its upper end contacts with limit switch, and the Vibration on Start-up device realizes shaking automatically the storehouse, makes materials flow recover normal.

Below, in conjunction with embodiment the utility model is described further:

Fig. 1 is a materials flow control monitor unit scheme drawing.

Several vibrators 2 are installed on the feed bin 1, materials flow 6 is run on the belt feeder 7 by gate 8, above the materials flow 6 between gate 8 and the belt feeder 7, install one and survey flitch 5, surveying flitch 5 is fixed on the axle sleeve 10, axle sleeve 10 is assemblied on the anchor shaft 4, a limit switch 3, the startup of may command vibrator 2 are equipped with in anchor shaft 4 tops.

Fig. 2 is a feeder vibrator electrical schematic diagram.When manual operation, select switch GHK is put into manual position; When operating automatically, select switch GHK is put into automated location, and JXK is the limit switch contact, and D is a vibrator motor.

Fig. 3 makes scheme drawing for surveying flitch.Survey flitch 5 and be fixed on the axle sleeve 10, axle sleeve 10 is assemblied on the anchor shaft 4.It can be dull and stereotyped surveying flitch 5, also can be the flap that certain angle is arranged.

The process that adopts this device that materials flow is monitored is as follows:

When materials flow moved, the lower end of surveying flitch 5 was lifted in mobile materials flow, made to survey flitch 5 upper ends and break away from limit switch 3, and the JXK in the feeder vibrator circuit disconnects, and vibrator is and stops the material state; When materials flow generation fracture, it is sagging automatically by deadweight to survey flitch 5 lower ends, surveying flitch 5 upper ends contacts with limit switch 3, make the limit switch JXK closure in the vibrator circuit, vibrator motor D begins to start, and has realized shaking automatically the storehouse, after materials flow recovers normally, materials flow will be surveyed flitch and be lifted forward, break away from the limit switch, and vibrator stops vibration.So circulation realizes the automatic monitoring to the feeder materials flow, and storehouse automatically shakes.

The utility model cost is lower, and is simple and reasonable, easy to maintenance, can adapt to production environments such as dust, high temperature, eliminated the generation of feeder fracture phenomenon, guarantees the quality of production.

Claims

1, a kind of materials flow control monitor unit, form by the materials flow supervision and the storehouse two parts that shake automatically, it is characterized in that the materials flow monitor portion is made up of with the solid axle (4) that is fixed on the place ahead in the materials flow the survey flitch (5) that is fixed on the axle sleeve (10), axle sleeve (10) is assemblied on the anchor shaft (4), surveying flitch (5) can be flat board or flap, one end contacts with materials flow (6), and an end can touch limit switch (3); Automatically the storehouse part of shaking is made up of some vibrators (2) that limit switch (3) is contained on the feed bin (1).
