Description

Build-up welding sieve plate with gradually-changed sieve holes

Technical Field

The utility model belongs to the technical field of the sieve, concretely relates to gradual change sieve mesh build-up welding sieve.

Background

Screening plates with various hole patterns such as casting comb teeth and casting rectangular holes are generally adopted in screening of a coking plant. The screen bars in the casting comb tooth sieve plate are not integrally cast, the tooth tip part is easy to wear, effective sieve pores are enlarged, and the sieve pores are easy to run thick. The sieve pores in the cast rectangular sieve plate are rectangular, and particles close to the sieving granularity are not easy to sieve due to the irregular shape of coke and the rectangular sieve pores. The sieve plate needs processes of moulding, mould carving and the like due to the casting of the sieve bars or the casting of the sieve surface, and has the disadvantages of complex manufacturing process, poor precision and high damage rate.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect among the prior art and provide a gradual change sieve mesh build-up welding sieve that structural design is ingenious, the screening precision is high, application scope is extensive and simple installation.

The purpose of the utility model is realized like this: including the sieve plate body, the row equipartition has a plurality of sieve mesh on the sieve plate body, and the sieve mesh of adjacent two lines is crisscross to be set up, and wherein single sieve mesh one end is small circle arc, and the other end is orthodrome, and the upper and lower both ends of small circle arc and orthodrome are connected through the tangent line.

Preferably, the build-up welding sieve plate with the gradually-changed sieve holes is cut by laser or plasma.

The utility model has the advantages of structural design is ingenious, the screening precision is high, application scope is extensive, the simple installation, long service life, be particularly useful for the screening of coke-oven plant.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, in which like reference numerals refer to like parts in the drawings. For the sake of simplicity, only the parts related to the utility model are schematically shown in the drawings, and they do not represent the actual structure as a product.

As shown in fig. 1, the utility model relates to a gradual change sieve mesh build-up welding sieve, including sieve plate 1, the in line equipartition has a plurality of sieve mesh 2 on sieve plate 1, and two adjacent lines of sieve mesh 2 are crisscross to be set up, and wherein 2 one end of single sieve mesh are small circle arc, and the other end is the orthodrome, and the upper and lower both ends of small circle arc and orthodrome are connected through the tangent line. The build-up welding sieve plate with the gradually-changed sieve holes is cut by laser or plasma.

The utility model is particularly suitable for a sieve of screening diameter at 5mm above large granule coke. The manufacturing process is that wear-resistant sieve plates with different apertures are manufactured on a surfacing steel plate through laser or plasma, the sieve holes in the sieve plates are gradually enlarged from small holes to large holes, the sieve holes have small and big heads, namely the small and big heads are divided into a narrow upper part and a wide lower part, the sides of the small and big heads are arc-shaped, and the sieve holes are arranged in a staggered mode so that materials can be screened fully.

The utility model discloses gradual change sieve mesh build-up welding sieve adopts laser or plasma to cut the system, and the material flow direction is from little to big, and sieve mesh staggered arrangement makes the material can more pass through the sieve easily, and screening efficiency is high.

The utility model discloses a build-up welding steel sheet is the high alloy wearing layer that has high rigidity, high wearability at ordinary steel sheet or some other steel sheet surfacing compound one deck, and this wear-resisting steel sheet has bimetallic property, and the high wearability on working layer and the high toughness of moulding on base member layer promptly provide convenient mechanical connection and welded connection condition for industrial application. Because of the difference between the application field and the working condition of the surfacing steel plate, such as the influence of factors such as the size of the bearing stress, the impact condition, the size of the material, the hardness, the flow rate, the impact angle, the working temperature and the like, the wear resistance of the surfacing steel plate is different, and under the normal condition, the wear resistance has the following statistical data: (1) relative low carbon steel: 20-25 times (2) of relative high manganese steel: 5-10 times (3) of relative tool steel: 5 to 10 times.

The utility model discloses the screening precision is high. The product adopts the processes of laser or plasma cutting and the like, and the aperture is accurate, so the granularity of the undersize material can well meet the requirement of a user. The above examples are only specific illustrations of feasible embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments, modifications and alterations without departing from the technical spirit of the present invention are intended to be included in the scope of the present invention.
