Multilevel energy-saving drying spiral sieve

Abstract

The invention discloses a multilevel energy-saving drying spiral sieve. The multilevel energy-saving drying spiral sieve comprises a sealed barrel, a foundation column, an adjusting-controlling motor, a support and an air blower. A lug seat on the outer wall of the sealed barrel is installed on the foundation column. A microwave generator and an electric heater are installed on the outer wall of the sealed barrel. A rotary shaft connected with the adjusting-controlling motor is arranged between shaft seats in the sealed barrel. A feed hopper with a baffle, and an air outlet pipe with a filter screen are installed at the top end of the sealed barrel. A check valve on the air outlet pipe is connected in the middle of the side wall of the sealed barrel through a heat recovery pipe. A spiral sieve body is arranged between each of three layers of spiral frames and the rotary shaft. The side wall and the bottom end of the sealed barrel are provided with discharge plates and discharge pipes correspondingly, and the discharge plates and the discharge pipes are each provided with a vibrator. Four layers of conveyer belts are installed on the part, close to the foundation column, of the support. The air blower is communicated with the electric heater and the sealed barrel through pipelines. The multilevel energy-saving drying spiral sieve is simple in structure, reasonable in design, good in sealing effect, capable of screening out materials with different grain sizes and meeting the need of actual production, good in screening effect, high in work efficiency and good in energy-saving effect and has a drying function.

Description

technical field [0001] The invention relates to the field of screening equipment, in particular to a multi-stage energy-saving drying spiral screen. Background technique [0002] In order to separate the large and small ore materials, it is usually necessary to screen the ore materials through a screen. The existing screen meshes are all directly screened or multi-stage screening. The hole falls, and the coarse ore remains on the screen. This kind of screen drying device has many defects. Due to the poor vibration effect of the screen, the coarse ore left on the screen will block the screen holes and affect the screening effect, so the screening efficiency is low. , the use effect is poor; and the mineral material is easy to overflow from the mesh screen, which not only wastes the mineral material but also pollutes the environment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a multi-stage energy-saving drying spiral screen with hig...

[0002] In order to separate the large and small mineral materials, it is usually necessary to screen the mineral materials through a screen. The existing screens are directly screened or multi-stage screened, and the mineral materials are dumped on the screen. The hole falls, and the coarse mineral material stays on the screen. There are many defects in this drying net device. Because the vibration effect of the screen is not good, the coarse mineral material left on the screen will block the screen holes and affect the screening effect, so the screening efficiency is low. , the use effect is poor; and the mineral material is easy to overflow from the mesh screen, which not only wastes the mineral material but also pollutes the environment
