Description
Technical field
The utility model belongs to tungsten powder process field, is specifically related to a kind of tungsten carbide powder automatic dry screen device.
Background technology
Tungsten carbide powder is raw material with metal tungsten powder and carbon black, is made into compound by a certain percentage, loaded by compound in graphite boat, is placed in carbon-tube oven or high intermediate frequency electrification stove, carbonizes at a certain temperature, then through ball milling, screening.Ball milling wherein refers to when ball mill rotates, and due to the rubbing action between abrasive body and ball mill inwall, fallen by abrasive body after on the direction band rotated, such material is just continuously pulverized again.But often after ball milling link, the material that ball mill is poured out all becomes caking, and caking is unfavorable for subsequent treatment, therefore sieves link and plays an important role.
Be divided into dry screen and wet screening, caking separated it is desirable that dry screen.Existing dry screen technology is artificial dry screen mainly, and the dry screen time is long, efficiency is low, and tungsten carbide powder flies upward in dry screen process, causes the loss of tungsten carbide powder, endangers the healthy of screening personnel simultaneously.
Utility model content
(1) technical problem that will solve
The utility model in order to overcome prior art dry screen efficiency low, there is tungsten carbide powder loss and the shortcoming of health hazard, the technical problems to be solved in the utility model is to provide a kind ofly does not exist tungsten carbide powder loss and health hazard, tungsten carbide powder automatic dry screen device that dry screen efficiency is high.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides so a kind of tungsten carbide powder automatic dry screen device, include screening tank, upper bracket, vibration motor, standard screen, dust sensor, spring, lower carriage, PLC control system and discharge valve, standard screen is provided with in described screening tank, dust sensor is provided with below described standard screen, the discharging opening of described screening tank is provided with discharge valve, the top of described screening tank is provided with upper bracket, the two ends of described upper bracket are respectively provided with vibration motor, described upper bracket is connected with lower carriage by spring, the bottom of described lower carriage is provided with pulley, described vibration motor, dust sensor is all connected with PLC control system with discharge valve.
Preferably, described discharge valve is electromagnetic valve.
Operation principle: the tungsten powder caking poured out by ball mill puts into screening tank, and tungsten powder caking drops on standard screen, and PLC control system sends a signal to vibration motor, and vibration motor starts vibrations; Because upper bracket is fixedly connected on the top of screening tank, upper bracket is connected with lower carriage by spring, under the effect of vibration motor, and screening tank vertical tremor, the tungsten powder caking on standard screen splits into more fritter gradually under vertical tremor effect; Under the filtration of standard screen, the caking that volume is larger cannot pass through standard screen, still stays on standard screen, is then dropped into the bottom of screening tank by the material of standard screen; Dust sensor below standard screen detect screening tank in dust concentration lower than setting value time, send a signal to PLC control system, after PLC control system detects the signal of dust sensor, send a signal to vibration motor and discharge valve, vibration motor quits work, discharge valve is opened, and material falls into recycling can and makes subsequent treatment; Owing to being provided with pulley bottom lower carriage, the utility model can move everywhere.
(3), there is not tungsten carbide powder loss and health hazard in beneficial effect: the utility model structure is simple, easy to operate, takes hermetically sealed can; Adopt PLC control system, achieve Automated condtrol, improve dry screen efficiency; Lower carriage is equipped with pulley, can move everywhere, is applicable to multiple place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-screens tank, 2-upper bracket, 3-vibration motor, 4-standard screen, 5-dust sensor, 6-spring, 7-lower carriage, 8-PLC control system, 9-discharge valve, 10-discharging opening, 11-pulley.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
embodiment 1
A kind of tungsten carbide powder automatic dry screen device, as shown in Figure 1, include screening tank 1, upper bracket 2, vibration motor 3, standard screen 4, dust sensor 5, spring 6, lower carriage 7, PLC control system 8 and discharge valve 9, standard screen 4 is provided with in screening tank 1, dust sensor 5 is provided with below standard screen 4, the discharging opening 10 of screening tank 1 is provided with discharge valve 9, the top of screening tank 1 is provided with upper bracket 2, the two ends of upper bracket 2 are respectively provided with vibration motor 3, upper bracket 2 is connected with lower carriage 7 by spring 6, the bottom of lower carriage 7 is provided with pulley 11, vibration motor 3, dust sensor 5 is all connected with PLC control system 8 with discharge valve 9, discharge valve 9 is electromagnetic valve.
embodiment 2
A kind of tungsten carbide powder automatic dry screen device, as shown in Figure 1, include screening tank 1, upper bracket 2, vibration motor 3, standard screen 4, dust sensor 5, spring 6, lower carriage 7, PLC control system 8 and discharge valve 9, standard screen 4 is provided with in screening tank 1, dust sensor 5 is provided with below standard screen 4, the discharging opening 10 of screening tank 1 is provided with discharge valve 9, the top of screening tank 1 is provided with upper bracket 2, the two ends of upper bracket 2 are respectively provided with vibration motor 3, upper bracket 2 is connected with lower carriage 7 by spring 6, the bottom of lower carriage 7 is provided with pulley 11, vibration motor 3, dust sensor 5 is all connected with PLC control system 8 with discharge valve 9, discharge valve 9 is electromagnetic valve.
The tungsten powder caking poured out by ball mill puts into screening tank 1, and tungsten powder caking drops on standard screen 4, and PLC control system 8 sends a signal to vibration motor 3, and vibration motor 3 starts vibrations; Because upper bracket 2 is fixedly connected on the top of screening tank 1, upper bracket 2 is connected with lower carriage 7 by spring 6, under the effect of vibration motor 3, and screening tank 1 vertical tremor, the tungsten powder caking on standard screen 4 splits into more fritter gradually under vertical tremor effect; Under the filtration of standard screen 4, the caking that volume is larger cannot pass through standard screen 4, still stays on standard screen 4, is then dropped into the bottom of screening tank 1 by the material of standard screen 4; Dust sensor 5 below standard screen 4 detect screening tank 1 in dust concentration lower than setting value time, send a signal to PLC control system 8, after PLC control system 8 detects the signal of dust sensor 5, send a signal to vibration motor 3 and discharge valve 9, vibration motor 3 quits work, discharge valve 9 is opened, and material falls into recycling can and makes subsequent treatment; Owing to being provided with pulley 11 bottom lower carriage 7, the utility model can move everywhere.
