Description

Powder sieving machine with external vibrator

The utility model device belongs to the field of powder screening machine equipment. It is more suitable for the vibration source external metal powder screening machine device.

In the prior art, the commonly used equipment for sieving treatment of superalloy powder is to adopt a sieve device in a rigid and airtight working room with a whole set of sieving mesh layers on the upper layer, which can generally be divided into upper and lower layers according to requirements. , middle and lower layers, and each layer of screen is connected with its own powder delivery pipe, and the metal powder with different particle sizes obtained after screening is transported to the powder storage tank with different requirements, so as to achieve the screening of the powder particle size classification purposes. A vibrator is installed on the lower layer of the sieve in the airtight chamber. The working procedure of the powder sieving equipment is to first seal and evacuate the working chamber, and then refill the protective gas with a certain pressure. The vibrator and the sifter in the sealed chamber work under the same conditions. Its main disadvantage is that due to the pollution source caused by the poor working environment of the vibrator motor, the sieved metal powder is often polluted. The reason is that the heat dissipation effect of the motor is poor, the electrical circuit is easy to burn, and the arc produces smoke and dust. The bigger problem is that the vibrator is installed in a narrow and confined space, which is very difficult for the assembly and disassembly, maintenance and repair of each component.

The purpose of the utility model is to propose a simple, economical and reasonable structure, the product will not be polluted and the external vibrator powder screening machine device is easy to maintain.

According to the purpose of this utility model, the specific structure of the vibrator-mounted powder screening device we propose can be described in detail according to the following drawings. Accompanying drawing 1 is the front structure schematic diagram of the utility model device, and accompanying drawing 2 is the side structure schematic diagram of this device. In the accompanying drawings, 1 is the sieve bracket, 2 is the sieve, 3 is the outlet, 4 is the bracket rod, 5 is the vibration eccentric wheel, 6 is the motor, 7 is the motor bracket, 8 is the spring soft connection , 9 is a sifter supporting plate, 10 is a vibrating pad, and 11 is a vibrating plate. The device of the utility model is to improve the deficiencies in the prior art. The composition of the device is that a sieve device 2 is installed in the sieve device bracket 1, and the sieve device 2 is an independently sealed vacuum or gas-protected powder sieve The cavity is equipped with a discharge port 3 on the edge of each screening layer of the sieve device 2, and the upper cover of the sieve device 2 is equipped with a feed port, an observation window and a vacuum tube, etc., and is characterized in that the sieve A sifter supporting plate 9 with a convenient opening is welded on the separator bracket 1, and a spring soft connection 8 connected with the sieving device is installed on the sieving device supporting plate 9, and a bottom edge of the sieving device 2 is also equipped with Vibrating pad 10 and vibrating plate 11 are firmly equipped with motor bracket 7 and bracket pull bar 4 at the lower end of vibrating plate 11, and motor 6 with eccentric wheel 5 is housed on motor bracket 7. Other features of this device are that the vibrating plate 11 can be directly connected with the bottom edge of the screener 2 . The motor bracket 7 can be a right-angle bracket, or a grooved bracket. The convenient opening for installation on the sieve device supporting plate 9 can be a hole pattern, and can also be a hole pattern with an edge. The unique feature of this vibrating external sieve device is that the sieve device 2 and the vibrating part are composed of two independent bodies. Powder screening, powder classification and other processes will not be polluted by the outside world, and the vibrator installed in the lower part of the screening body is the vibration source, which transmits the vibration force through the vibration plate 11, vibration pad 10 and spring soft connection Transfer to the sifter 2 for sieving powder classification. Can have hole in the center of sifter supporting plate 9, for easy installation, also can open this hole and an edge of supporting plate 9, very convenient to installing vibration equipment like this.

Compared with the prior art, the device of the utility model has the advantages of simple and reasonable structural design, economical and practical equipment cost, no pollution to powder products, especially convenient and reasonable installation and maintenance of equipment, maintenance and adjustment.
