Abstract

The invention discloses a vibrating screen for a metal powder grinder, and the vibrating screen comprises a screen body, wherein the screen body is provided with a feed inlet; a first-layer screen, a second-layer screen, a third-layer screen are arranged in the screen body; the screen body between the first-layer screen and the second-layer screen is provided with a coarse material outlet; and a fine material outlet is arranged on the screen body behind the third-layer screen. The working principle of the vibrating screen is as follows: metal powder which is ground enters the screen body from the feed inlet, and is respectively screened by the first-layer screen, the second-layer screen and the third-layer screen, the metal powder with grain sizes between 60 and 80 meshes is output from the coarse material outlet, and the metal powder with the grain sizes smaller than 100 meshes is output from the fine material outlet, wherein the first-layer screen is a 60-mesh stainless steel screen mesh, the second-layer screen is an 80-mesh stainless steel screen mesh, and the third-layer screen is a 100-mesh stainless steel screen mesh. Therefore, the purpose of separating the metal powder with different grain sizes is realized quite conveniently, and the structure of the vibrating screen is simple.

Description

A kind of vibratory sieve that is used for the metal dust pulverizer

Technical field

The present invention relates to a kind of auxiliary equipment of metal dust pulverizer.

Background technology

Metal dust such as copper powder, iron powder has purposes widely as the important raw and processed materials of industry.So the metal pulverizer that specially metal powder is broken into powder is arranged, present metal dust pulverizer generally all is directly to collect the back by gathering-device after metal is pulverized to use, but raising along with instructions for use, requirement for the metal dust particle size is also improving, also different for its standard of different purposes, so need be in crushing metal with the powder of different-grain diameter separately, original metal dust pulverizer can not satisfy the requirement that separates to the different-grain diameter metal dust.

Summary of the invention

The purpose of this invention is to provide a kind of vibratory sieve that is used for the metal dust pulverizer that the metal dust of different-grain diameter can be separated.

Technical scheme of the present invention: a kind of vibratory sieve that is used for the metal dust pulverizer, comprise sieve nest, described sieve nest is provided with charging aperture, be provided with one deck sieve, two layers of sieve, three layers of sieve in the sieve nest, one deck sieve is provided with the coarse fodder outlet with sieve nest between two layers of sieve, and the sieve nests of three layers of sieve back are provided with fines and export.

Described sieve nest is provided with suction port.

Described sieve nest is provided with the connecting plate that is used to install vibrating motor.

Described one deck sieve is 60 order stainless steel mesh, and two layers of sieve are 80 order stainless steel mesh, and three layers of sieve are 100 order stainless steel mesh.

Described sieve nest is fixed on the frame.

The operation principle of vibratory sieve of the present invention, metal dust charging aperture after crushed enters sieve nest, sieve through one deck again, two layers of sieve, three layers of screening are not sieved, one deck sieve is 60 order stainless steel mesh, two layers of sieve are 80 order stainless steel mesh, three layers of sieve are 100 order stainless steel mesh, particle diameter is exported by the coarse fodder outlet at 60～80 purpose metal dusts, particle diameter is narrower than 100 purpose metal dusts by fines outlet output, thereby reached the purpose that the metal dust with different-grain diameter makes a distinction, very convenient, Structure of Vibrating Screen is simple, and the dust that suction port is used for producing is set on the sieve nest siphons away.

The specific embodiment

As Fig. 1, the metal dust crushing system is made up of metal pulverizer, vibratory sieve and three parts of dust collect plant, and Fig. 1 is respectively metal pulverizer and dust collect plant part about the top, and the below is a vibratory sieve of the present invention.

Raw metal is joined in the pulverizer 15 by loading hopper 16, and pulverizer 15 is broken into powder with metal powder, and metal dust is screened by the vibratory sieve that storage bin hopper 13 comes out to enter into the below.The storage bin hopper limit is provided with dust collect plant, and dust collect plant starts high pressure positive blower 18 and carries out air blast, by dust suction bucket 12, aspiration channel 17 and discharge pipe 19 dust that produces is drawn into dust arrester 11, and thinner particulate then arrives deduster 20 by dust removing tube 14 and collects.

As Fig. 2,3,4,5, a kind of vibratory sieve that is used for the metal dust pulverizer, comprise sieve nest 10, described sieve nest 10 is provided with charging aperture 1, be provided with 3, three layers of sieve 4 of 2, two layers of sieve of one deck sieve in the sieve nest 10, three layers of sieve are divided into four parts with sieve nest 10, and the sieve nest that the sieve nest between 2 and two layers of sieve 3 of one deck sieve is provided with 6, three layers of sieve of coarse fodder outlet, 4 back is provided with fines outlet 7.Described sieve nest 10 is provided with suction port 8.Described sieve nest 10 is provided with the connecting plate 5 that is used to install vibrating motor.Described one deck sieve 2 is 60 order stainless steel mesh, and two layers of sieve 3 are 80 order stainless steel mesh, and three layers of sieve 4 are 100 order stainless steel mesh.Described sieve nest 10 is fixed on the frame 9.

Frame 9 need be by the supporting separately design of the concrete place of client environment when making.9 of sieve nest 10 and frames have 8 spring shock-proof.The inclination angle was generally 15 °～20 ° when sieve nest 10 was installed, and specifically can regulate when mounted.Vibration is the vibrating motor generation of 0.55W by power.

Metal dust is after crushed entered the charging aperture 1 of vibratory sieve by the storage bin hopper among Fig. 1 13, sieve respectively through 3, three layers of sieve 4 of 2, two layers of sieve of one deck sieve again, one deck sieve is 60 order stainless steel mesh, two layers of sieve are 80 order stainless steel mesh, three layers of sieve are 100 order stainless steel mesh, on the sieve nest 10 between 2 and two layers of sieve 3 of one deck sieve coarse fodder outlet 6 is set, by coarse fodder outlet 6 outputs, particle diameter is narrower than 100 purpose metal dusts and exports 7 outputs by being arranged on three layers of fines on the sieve nest after the sieve 4 after the screening of three layers of sieve 4 particle diameter at 60～80 purpose metal dusts like this.
