Abstract

A kind of screening plant that can be cleared up automatically, including sieve nest, the vibrating motor on sieve nest, the screen cloth being arranged on sieve nest, it is characterised in that：Also include the switching mechanism that driving screen cloth is overturn between operating position and clear position, the screen cloth is more than the angle of inclination of operating position at the angle of inclination of clear position, so that material of the accumulated plugging on the screen cloth can be cleaned, when having bulky grain material or binding material is stuck on screen cloth grid, screen cloth can be driven to be overturn from operating position to clear position by switching mechanism, the screen cloth of clear position has angled angle of inclination, coordinate the vibration of vibrating motor bulky grain material or binding material can be shaken off from screen cloth again, so as to realize self-cleaning function.

Description

A kind of screening plant that can be cleared up automatically

Technical field

It the utility model is related to a kind of screening plant.

Background technology

Asphalt mixture hot-mix plant recycling technology is a kind of technology for being recycled waste asphalt mixture, waste and old Asphalt be sent into hot-mix plant recycling equipment processing before technical process be:Milling is carried out to waste asphalt pavement Or excavation, crushing and screening, stacking, the hot in-plant reclaimed heating of feeding.In the process, particularly in waste asphalt mixture Carry out easily forming relatively large ultra-specification sized particles after stacking for a long time after crushing and screening, milling or excavated The large volume of impurity such as iron filings, wood chip is brought in journey into, if this ultra-specification sized particles or impurity are sent into plantmix's heat accidentally Again after generating apparatus, elevator equipment fault will be very likely caused, transporting chute blocks, and drying roller bonds serious, Yi Jiyan Ghost image rings the harm such as finished product material quality.Under normal circumstances, existing coarse granule screening plant is equipped with fixed gauge diagrid net, is advised when running into Lattice size approaches, or waste asphalt mixture moisture content is higher or when viscosity is larger, and screen cloth easily blocks, so as to lead Cause feeding difficult, will cause to underproduce or the risk of fracture.Manual intervention is such as arranged, then needs to spend more manpower and materials, So that operating cost increases, and it is less efficient.

The content of the invention

The purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of to clear up accumulated plugging screen cloth automatically The screening plant of material.

The purpose of this utility model is realized by following technical solution：

It is a kind of can self-cleaning screening plant, including sieve nest, the vibrating motor on sieve nest, be arranged on sieve nest Screen cloth, it is characterised in that：Also include the switching mechanism that driving screen cloth is overturn between operating position and clear position, the screen cloth It is more than the angle of inclination of operating position at the angle of inclination of clear position, so that material of the accumulated plugging on the screen cloth can To be cleaned.

Further, the screen cloth can be turningly arranged on the sieve nest around horizontally disposed rotation axis, the rotation Shaft axis are parallel with plane where the screen cloth or overlap.

Further, the turning device is on the screen cloth and coaxially arranged with the rotation axis including being fixedly installed on Rotating shaft, the swing arm being fixedly installed in rotating shaft and the cylinder being articulated between swing arm and the sieve nest.

Further, the turning device includes the cylinder for driving the screen stencil turning.

Further, the sieve nest has biside plate positioned opposite, and the both sides of the screen cloth pass through coaxially arranged two Support shaft rotatable support is between biside plate.

Further, the vibrating motor includes setting up two on the outside of biside plate separately.

Further, the sieve nest bottom is provided with support frame.

Further, the stock guide for guiding coarse fodder is provided with support frame as described above.

Further, the screen cloth is 10-30 ° at the angle of inclination of operating position, at the angle of inclination of clear position For 70-90 °.

The utility model has the advantages that：

When having bulky grain material or binding material is stuck on screen cloth grid, screen cloth can be driven by switching mechanism from working position Put upset to clear position, the screen cloth of clear position and have angled angle of inclination, then coordinate the vibration of vibrating motor can be by greatly Particulate material or binding material shake off from screen cloth, so as to realize self-cleaning function.

Brief description of the drawings

The utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is structural representation of the present utility model, and screen cloth is in operating position.

Fig. 2 is structural representation of the present utility model, and screen cloth is in clear position.

Embodiment

It is shown referring to Figures 1 and 2, it is a kind of can self-cleaning screening plant, including support frame 4, sieve nest 1, vibrating motor 12, Screen cloth 2, stock guide 5 and switching mechanism.

Sieve nest 1 is arranged on the top of support frame 4, and sieve nest 1 has parallel relative biside plate 11, and vibrating motor 12 includes difference Two of the outside of biside plate 11 are arranged on, screen cloth 2 can be turningly arranged on sieve nest 1 around horizontally disposed rotation axis, rotation Axis is parallel with the place plane of screen cloth 2 or overlaps, and the both sides of specific screen cloth 2 are rotatably propped up by two coaxially arranged support shafts Hold between biside plate 11, two support shafts are arranged along rotation axis.

Turning device is used to drive screen cloth 2 to overturn between operating position and clear position, including is fixedly installed on screen cloth 2 The upper and rotating shaft 22 coaxially arranged with rotation axis, the swing arm 32 being fixedly installed in rotating shaft 22 and it is articulated in swing arm 32 and sieve nest Cylinder 31 between 2, screen cloth 2 is more than the angle of inclination of operating position at the angle of inclination of clear position, so that accumulated plugging Material on the screen 2 can be dropped by vibration, and stock guide, which is arranged on support frame, to be used to guide the thing from the discharge of the top surface of screen cloth 2 Material.

It is described above, preferred embodiment only of the present utility model, therefore the utility model implementation can not be limited with this Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description all should still belong to this In the range of utility model patent is covered.
