Technical Field
The invention relates to a production device of titanium sponge, in particular to a screening device for product granularity in titanium sponge crushing production.
Background
The whole process for industrially producing the titanium sponge mainly comprises chlorination, magnesium electrolysis, titanium sponge reduction distillation and titanium sponge crushing and packaging processes. The packaging of the titanium sponge products is very strict, and the products cannot contain any impurities of non-titanium products such as iron nails, cotton threads, rubber, welding slag and the like, so that metal equipment and metal pipelines are arranged in the whole production workshop during crushing and packaging, the requirement on the granularity of the titanium sponge products is particularly strict, the granularity of the products cannot exceed the standard requirement, and otherwise the whole batch of products is returned as unqualified products. The method comprises the following steps that after being crushed by a coarse crusher, sponge titanium enters a medium crusher through a conveyor belt, products are crushed by the medium crusher and then pass through a vibrating screen, the vibrating screen is used for classifying the products with two particle sizes, the products with the particle sizes reaching the particle sizes required by the medium crusher enter a fine crusher for crushing, unqualified products with large particle sizes pass through the medium crusher for crushing, the products with unqualified particle sizes enter the fine crusher for crushing after the particle sizes are qualified, the products with the large particle sizes pass through the medium crusher for crushing, and then the products with the two particle. According to the requirement of the national standard product on the granularity of 0.83-25.4mm, the product with the granularity of more than 25.4mm needs to be crushed by a fine crusher, and the product with qualified granularity is treated by the next procedure. When the particle size is completely controlled below 25.4mm, part of the product with the particle size smaller than 0.83mm is sieved again, and according to production practice, the size of the mesh of the sieve is required to be 2mm when the product with the particle size of 0.83mm is separated. In view of the above, there are the following problems: the noise of the vibrating screen is high, and the physical health of operators is seriously injured; after the product is crushed by the middle crusher, the qualified product with the product granularity smaller than 25.4mm is crushed by the fine crusher, and partial product is crushed with the unqualified granularity smaller than 0.83mm, so that the qualified rate of the product is reduced; after the particle size is smaller than 25.4mm after being crushed by the fine crusher, a product with the particle size smaller than 0.83mm is separated through one-time screening, and the production period is prolonged.
Disclosure of Invention
The invention aims to solve the technical problems that a vibrating screen generates harsh sound in the titanium sponge crushing production process, qualified products of titanium sponge granularity are secondarily crushed into unqualified products, and the crushing production process is long.
In order to solve the technical problems, the invention adopts the following technical scheme:
a screening device for product granularity in titanium sponge crushing production comprises a cylinder body 1, a circular ring 2, a large cylindrical screen 3, a shaft bracket 5 and a transmission shaft 6; a large cylindrical screen 3 is arranged in the cylinder body 1 and is connected with the cylinder body through a circular ring 2; the transmission shaft 6 is provided with a shaft bracket 5;
a cylindrical fine screen 4 is arranged between the cylindrical large screen 3 and the shaft bracket 5;
the inner circular surface of the cylindrical fine screen 4 is fixedly connected with the shaft bracket 5, and the outer circular surface of the cylindrical fine screen 4 is connected with the inner circular surface of the cylindrical fine screen 4 through round steel 7;
the length of the cylindrical fine screen 4 is greater than that of the cylindrical large screen 3; the length of the cylindrical large screen 3 is greater than that of the cylinder body 1;
the cylindrical fine screen 4 is provided with more than 50 holes, and the specification of the holes is 2 beta 2mm square holes or circular holes with the aperture phi 2 mm.
Adopt above-mentioned technical scheme this beneficial effect to be:
1. the invention overcomes the technical problem that the product with qualified granularity is crushed into the product with unqualified granularity after secondary crushing, and increases the grade rate and the qualification rate of the product.
2. The invention avoids using a vibrating screen, reduces the noise of a production workshop, protects the hearing of an operator and reduces occupational diseases.
3. The invention removes the last screening procedure in the titanium sponge crushing production and shortens the production time.

FIG. 1 is a schematic structural diagram of the present invention.
In the figure: 1-cylinder body, 2-circular ring, 3-cylinder large screen, 4-cylinder fine screen, 5-shaft bracket, 6-transmission shaft and 7-round steel.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, the screening device for the product granularity in the titanium sponge crushing production comprises a cylinder body 1, a circular ring 2, a large cylindrical screen 3, a shaft bracket 5 and a transmission shaft 6; a large cylindrical screen 3 is arranged in the cylinder body 1 and is connected with the cylinder body through a circular ring 2; the transmission shaft 6 is provided with a shaft support 5.
A cylindrical fine screen 4 is further provided between the cylindrical large screen 3 and the shaft support 5.
The inner circular surface of the cylindrical fine screen 4 is fixedly connected with the shaft bracket 5, and the outer circular surface of the cylindrical fine screen 4 is connected with the inner circular surface of the cylindrical fine screen 4 through round steel 7; the round steel 7 has the function of not preventing the product from being smoothly output from the screen and playing a role of fixing the screen.
