Abstract

The utility model provides a high-frequency welding sieve plate, which relates to the technical field of vibration fluidized bed drying machine accessories and comprises triangular wire strips (1) and reinforcing ribs (2), wherein a plurality of triangular wire strips (1) are in vertical arrangement, and a plurality of reinforcing ribs (2) are in transverse high-frequency welding on the upper ends of the triangular wire strips (1). The improvement is carried out in a section of length of the material inlet end of a vibration fluidized bed drying machine, the gaps between the triangular wire strips (1) for carrying materials are 0.2mm, the bed layer resistance can be reduced through the structure, and higher gap passing air speed can also be maintained, so the materials are ensured not to be leaked into a lower box body to the furthest degree in the actual application, and the requirement of continuous long-time operation of special materials can also be met.

Description

A kind of high-frequency welding sieve plate

Technical field:

The utility model relates to Vibratingfluidbeddrier accessory technical field, is specifically related to a kind of high-frequency welding sieve plate.

Background technology:

Present most widely used horizontal Vibratingfluidbeddrier, shape is very similar to common horizontal type fluidized-bed drying machine with basic structure.Difference is that the vibrated fluidized bed whole machine body is supported on the base by spring, and porous plate tilts to discharge end slightly, and vibrating motor is equipped with in the body one or both sides.Material relies on mechanical oscillation and perforation air-flow double action fluidisation, and travels forward under the vibration effect.Common vibrated fluidized bed sieve plate is contained in the lower box, participate in vibration together with lower box, aperture 2.5-3mm on the sieve plate, percent opening 3%-3.5%, vibrated fluidized bed when operation air-flow pass the gas speed 25-30m/s of aperture, when bigger, even, the loose material of dried particles, material can not pass aperture and drain in the lower box, therefore, the Vibratingfluidbeddrier continuous long-time running that can meet the demands.

Vibratingfluidbeddrier dried particles is thin, granularity is inhomogeneous, during the material of easy reunion; also bigger at feed end owing to humidity of materials; the material of just having added can not form stable fluidization immediately; causing fine small particles material to pass aperture drains in the lower box; along with the time increases; material in the lower box is cumulative, and the Vibratingfluidbeddrier cisco unity malfunction reruns after can only shutting down cleaning.

The utility model content:

The purpose of this utility model provides a kind of high-frequency welding sieve plate, it can reduce bed resistance, can keep higher wearing to stitch gas speed again, therefore in practice, keep material not drain in the lower box to greatest extent, satisfy the continuous long-time running of requirement also can satisfy to(for) special material.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises triangle strand and reinforcement, and several triangle strand is vertically arranged, and laterally ratio-frequency welding is connected to several reinforcement in the top.

Slit between the described triangle strand is 0.1-0.3mm.

The utility model improves in feed end one segment length of Vibratingfluidbeddrier, slit between the triangle strand of carrying material is 0.1-0.3mm, this structure can reduce bed resistance, can keep higher wearing to stitch gas speed again, therefore in practice, keep material not drain in the lower box to greatest extent, satisfied the continuous long-time running of requirement also can satisfy to(for) special material.

Description of drawings:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the vertical view of Fig. 1,

Fig. 3 is the left view of Fig. 1,

Fig. 4 is the A portion structure for amplifying schematic diagram of Fig. 3.

The specific embodiment:

With reference to Fig. 1-4, this specific embodiment by the following technical solutions: it comprises triangle strand 1 and reinforcement 2, and several triangle strand 1 is vertically arranged, and laterally ratio-frequency welding is connected to several reinforcement 2 in the top.

Slit between the described triangle strand 1 is 0.2mm.

This specific embodiment is improved in feed end one segment length of Vibratingfluidbeddrier, slit between the triangle strand 1 of carrying material is 0.2mm, this structure can reduce bed resistance, can keep higher wearing to stitch gas speed again, therefore in practice, keep material not drain in the lower box to greatest extent, satisfied the continuous long-time running of requirement also can satisfy to(for) special material.

Claims

1. a high-frequency welding sieve plate is characterized in that it comprises triangle strand (1) and reinforcement (2), and several triangle strand (1) is vertically arranged, and laterally ratio-frequency welding is connected to several reinforcement (2) in the top.

2. a kind of high-frequency welding sieve plate according to claim 1 is characterized in that the slit between the described triangle strand (1) is 0.1-0.3mm.
