Description
Technical Field
The utility model belongs to the technical field of high-purity refractory metal production, and particularly relates to an anti-pollution refractory metal powder closed treatment system.
Background
Refractory metals such as tungsten, molybdenum, tantalum, niobium and the like are increasingly applied to the sputtering target field and the aerospace field, and the application has very strict requirements on oxygen elements and other impurity elements, so that the purity of refractory metal powder is required to be more than 99.99 percent. The existing production mode is as follows: pouring the powder discharged from the furnace into a small storage bin manually, conveying the small storage bin to the side of a sieving machine, adding the powder into the sieving machine for multiple times manually, and adding the materials into a mixer manually after sieving is completed; after the material mixing is finished, the material is manually received, and the package is sealed after the material is weighed. Several problems exist in the process from the reduction of molybdenum powder out of the furnace to packaging and warehousing: (1) The manual participation links are more, other impurities can be possibly introduced, and the product quality is unstable; (2) The powder is exposed to the air for a long time in the whole process, so that the oxygen increment of key elements affecting the quality of the powder is about 200ppm, and the oxygen content of the packaged product is generally more than 800-1000 ppm; it is difficult to meet high purity powder customer requirements; (3) The powder flies in the operation process, the working environment of staff is poor, the labor intensity is high, and the physical health of staff is damaged.
Disclosure of Invention
The utility model aims to provide an anti-pollution refractory metal powder closed treatment system which is used for solving the problems that the quality of products is unstable and the requirements of high-purity powder are difficult to meet in the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
The utility model provides an antipollution refractory metal powder closed processing system, includes little feed bin, screening machine, first vacuum feeder, storage silo, automatic sampler, blendor, packagine machine, transfer feed bin and control system, wherein, the screening machine is installed on the installing support, and first vacuum feeder installs in the screening machine top, and its discharge gate is located the feed inlet of screening machine directly over; the discharge hole at the bottom of the small storage bin is connected to a first vacuum feeding machine through a conveying pipeline; the storage bin is arranged below the mounting bracket, and a feed inlet of the storage bin is positioned right below a discharge outlet of the screening machine; the discharge hole at the bottom of the storage bin is connected to the feed inlet of the mixer through a conveying pipeline, and the conveying pipeline is connected with a second vacuum feeder; the transfer bin is arranged below the mixer, and the feed inlet of the transfer bin is positioned right below the discharge outlet at the bottom of the mixer; the automatic sampler is arranged between the mixer and the transfer bin; the discharge port at the bottom of the transfer bin is connected to a third vacuum feeding machine through a conveying pipeline, the third vacuum feeding machine is arranged above the packaging machine, and the discharge port of the third vacuum feeding machine is positioned right above the feed port of the packaging machine; the control system is connected with the ultrasonic vibration sieve, the first vacuum feeder, the second vacuum feeder, the third vacuum feeder, the packaging machine and the automatic sampler.
The utility model also comprises the following other technical characteristics:
The bottom of the small storage bin is provided with a universal wheel.
The small storage bin is provided with a sealing cover plate.
The screening machine is provided with an ultrasonic device, and the ultrasonic device is connected with a control system.
The conveying pipeline adopts a PVC steel wire hose.
The mounting bracket adopts a steel structure bracket.
And fork truck grooves are formed in the bottoms of the storage bin and the transfer bin.
The blendor is located storage silo one side, and the second vacuum material loading machine is located blendor one side.
The lower part of the mixer is provided with a pneumatic vibrator.
And valves are arranged on the discharge ports of the small storage bin, the storage bin and the transfer bin.
Compared with the prior art, the utility model has the following technical effects:
1. reducing the increase of oxygen content in the material. After the previous materials are produced from the reduction furnace, the three working procedures of sieving, mixing and packaging are all manually operated, and the materials are exposed in the air for a long time.
After the closed system is used, the material circulation among the working procedures is conveyed through the closed pipeline, so that the foreign matters brought by manual operation can be effectively reduced, the increase of impurity elements such as calcium, silicon and the like caused by dust can be reduced, and the increase of the oxygen content exposed in the air can be reduced.
2. The material screening passing rate is controllable. The amount and time of the previous feed from bin 1 to screen 2 was controlled manually, for example, by requiring the operator to add 13-15 kg of material every 10 minutes, and remove oversize after 60 minutes of screening. However, in actual operation, operators often cannot feed materials according to requirements, and the materials often exceed the requirements, so that the service life of the screen is shortened, the screen is damaged, and the like, and the screening is invalid, and the screen is reworked. Or the operator does not remove the oversize at the prescribed time, resulting in some low quality oversize material also entering the normal undersize material.
After the first vacuum feeding machine 3 and the ultrasonic device 6 are used, the weight of the materials entering the sieving machine each time can be automatically controlled according to the quality condition of the materials, and the sieving time of each time can be controlled, so that the sieving passing rate which we want to reach is obtained.
3. The sampling is more representative. After the material mixing is finished by the mixer 9 in the past, a discharging main valve is opened for sampling. The disadvantage is that the sampling point is one, and the representativeness is poor. And open total valve sampling troublesome operation, the material that flows out when sampling far exceeds the demand of sampling, causes certain material extravagant.
After using the automatic sampler 13, multiple samples can be taken, and multiple points can be taken, so that the sampling result is more representative. Meanwhile, the operation is convenient, the sampling is carried out according to the required quantity, and the material waste is avoided.
4. Avoiding the foreign matters from being brought in during the packaging process. After the previous mixing is finished, the valve is opened manually and the mixture is put into 20 to 30 small barrels, then the weighing is carried out one by one, and the package is carried out. The defect is that labor intensity is high, secondary weighing is needed, material exposure time is long in the operation process, foreign matters are easy to bring in, and customer complaints are caused.
After the third vacuum feeding machine 11 and the packaging machine 12 are used, the third vacuum feeding machine is accurately weighed by a blanking scale, and the packaging is completed by automatic blanking, and the sealing is finished. No manual filling is needed, no manual binding and sealing are needed, and foreign matters are prevented from being brought in.
