Embodiment 1

[0024] see Figure 1~2 , in an embodiment of the present invention, a combined powder screening machine includes a sieve body support column 1, a lower sieve body 2 and an upper sieve body 3 are fixedly arranged on the sieve body support column 1, and the lower sieve body 2 and the upper sieve body The sieve body 3 is a cuboid structure, the lower sieve body 2 and the upper sieve body 3 are inclined to the left and lower; the upper sieve body 3 is located directly above the lower sieve body 2; the lower sieve body 2 and the upper sieve body 3 There are several layers of sieves 4 inside, the sieves 4 in the lower sieve body 2 gradually decrease from top to bottom, and the sieves 4 in the upper sieve 3 gradually decrease from top to bottom. small, so as to carry out step-by-step screening; through the setting of the multi-layer screen 4, the multi-stage screening inside the upper screen body 3 and the lower screen body 2 is realized, which makes the cement powder screening furth...

Embodiment 2

[0028] see image 3 , on the basis of embodiment 1, it also includes an outer casing 7, the upper sieve body 3, the lower sieve body 2, and the distributor 6 are all located in the outer casing 7 to prevent dust from being raised; the feed inlet of the distributor 5 It extends through the outer shell 7 to the outside of the outer shell 7, which is convenient for feeding; the top of the outer shell 7 is provided with a dust collection port 8, and by connecting a vacuum cleaner at the dust collection port 8, the dust is recovered by the vacuum cleaner, which completely solves the problem of vibrating screen dust problem, more environmentally friendly.

Abstract

The invention discloses a combined powder sieving machine, and relates to the technical field of powder sieving. The combined powder sieving machine comprises a sieving body supporting column, a lowersieving body and an upper sieving body are fixedly arranged on the sieving body supporting column, each of the lower sieving body and the upper sieving body is of a rectangular structure, the lower sieving body and the upper sieving body tilt to the lower left portion, the upper sieving body is located directly above the lower sieving body, a plurality of layers of sieving nets are arranged in each of the lower sieving body and the upper sieving body, and a distributor is arranged in a feeding opening of the right side of each of the upper sieving body and the lower sieving body; and each distributor comprises a plurality of discharging openings matched with the sieving nets, and the discharging openings of each distributor extend to the upper right sides of the sieving nets respectively.The combined powder sieving machine uses a mechanical vibration sieving method to separate the powder from a roller press, a scheme of using high-energy-consuming wind power to separate the powder ina traditional process is completely changed, and the power consumption is effectively reduced; and the sieving capacity is dramatically improved through the combination of the upper sieving body andthe lower sieving body, and meanwhile, the size of the sieving machine is reduced.

Description

technical field [0001] The invention relates to the technical field of powder screening, in particular to a combined powder screening machine. Background technique [0002] The cement industry is a high energy consumption industry in my country, accounting for 40% of the total energy consumption of the national building materials industry. There is still a lot of room for reducing electricity consumption in the cement grinding process. Based on the existing clinker production, it is estimated that 30 billion kWh of electricity can be saved. Therefore, the progress of energy conservation and consumption reduction in the cement industry will play a significant role in the realization of the national energy conservation and consumption reduction goals. to a very important role. [0003] At present, the energy consumption of cement grinding is lower than that of the semi-finish grinding technology. The core of the technology is to adopt the front roller press scheme, and about ...
