Description

Warehouse-out and warehouse-cleaning device of circular warehouse

Technical Field

The invention relates to a circular stock bin, in particular to a delivery and cleaning device of the circular stock bin, belonging to the technical field of storage and discharge facilities.

Background

Materials such as grains, bean pulp and the like are usually stored in a silo for a long time, a silo discharging machine for outputting the materials is arranged at the bottom of the silo, and a discharge port of the silo is positioned at the center of the bottom of the silo. The traditional auger delivery machine conveys materials from the periphery to a discharge port positioned in the center. The central end of the auger is driven by a central driving mechanism, the central driving mechanism of the grain delivery machine comprises a main speed reducer and a coupler, the main speed reducer is positioned on the axis of the silo, the output shaft of the main speed reducer is connected with the driving end of the auger shaft through the coupler, and the outer end head of the auger shaft is supported on the tail mechanism through a tail end bearing.

When discharging, the main speed reducer drives the auger shaft to rotate through the coupler, and the auger shaft conveys the material to a silo discharge port in the center. The auger shaft rotates, and the tail mechanism drives the auger to move along the walking track, so that the auger rotates and revolves around the center of the silo, and materials on the whole circumference of the bottom can be conveyed to a discharge port of the silo.

The diameter of the silo is large, the length of the auger shaft is long, and the coupler and the main speed reducer which can align and bear bidirectional axial force and radial force are needed during installation, so that the processing and installation difficulty is increased.

The pulp discharging machine in the prior art can only adopt a screw conveyer discharging form due to poor pulp fluidity, and has high energy consumption, large investment and large processing difficulty; the coupler is required to be customized for the auger and the main speed reducer, and the cost is high.

For a raw grain silo for storing raw grain materials with better fluidity, such as soybeans, corns, wheat and the like, a plurality of discharge holes are usually arranged at the bottom of the silo. When the discharge ports are opened, the materials flow out of the discharge ports under the action of gravity and are conveyed out by the conveying belt. When the last material is about to be unloaded, the residual materials collected on the periphery of the storage bin can not automatically flow out and are accumulated on the periphery of the storage bin, and the materials retained in the storage bin must be thoroughly cleaned before new materials are stored. The emptying machine is usually pre-buried at the bottom of the raw grain bin to complete the final emptying.

The raw grain bin cleaner in the prior art also adopts a packing auger for discharging, and the bin cleaner cannot be used for a meal bin with poor liquidity. Except being equipped with central discharge gate in the clear storehouse machine feed bin, storehouse edge is with a plurality of discharge gates to being furnished with conveying equipment in each discharge gate below, many conveying equipment gather a bit again, cause the accessory equipment numerous, investment cost and consumption of power are big, and the operating cost is high, and installation and cost of maintenance are also high.

Based on the reasons, the large-scale raw grain bin and the meal bin are separately constructed at present, so that the investment cost is very high; but the raw grain bin and the meal bin can be commonly used in the process. At present, no universal delivery equipment is available, and the delivery equipment can deliver materials with good fluidity and can deliver materials with poor fluidity.

Disclosure of Invention

The invention aims to overcome the problems in the prior art, and provides the discharging and cleaning device of the circular storage bin, which has low operation energy consumption, can be suitable for materials with good fluidity, can also be suitable for materials with poor fluidity, and greatly reduces the construction cost of the storage bin.

In order to solve the technical problems, the discharging and cleaning device for the circular storage bin comprises a central rotating mechanism positioned in the center of the bottom of the storage bin, wherein the central rotating mechanism comprises a rotating cylinder body coaxial with the storage bin, a rotating top cap is arranged at the top of the rotating cylinder body, a rotating bottom plate is arranged at the bottom of the rotating cylinder body, the discharging device also comprises a main driving mechanism, a scraper discharging mechanism, a girder mechanism and a revolution travelling mechanism, the scraper discharging mechanism comprises a head shaft and a tail shaft which extend vertically, the head shaft is arranged at the head of the girder mechanism and driven by the main driving mechanism, and a driving chain wheel is arranged on the head shaft; the tail shaft is arranged at the tail part of the girder mechanism, and a driven chain wheel is arranged on the tail shaft; a chain is wound between the driving chain wheel and the driven chain wheel, and scrapers extending vertically are uniformly arranged on the chain at intervals; a silo conical surface which shrinks towards the center is arranged on the circumference of the lower part of the silo, the revolution travelling mechanism is positioned in an annular space below the silo conical surface, and a skirt plate which extends downwards is arranged on the circumference of the lowest end of the silo conical surface; the tail part of the girder mechanism is supported on the revolution travelling mechanism, the head part of the girder mechanism is inserted into the rotary cylinder, a scraper mechanism discharge port communicated with the rotary bottom plate is formed in the head part of the girder mechanism, and the scraper mechanism discharge port is located between the rotary cylinder and the head shaft.

Compared with the prior art, the invention has the following beneficial effects: when delivering from the warehouse or clearing the warehouse, main drive mechanism drive scraper blade discharge mechanism's head axle is rotatory, the epaxial drive sprocket of head passes through the chain and drives the epaxial driven sprocket of tail and rotate, the tail axle rotates in step, each scraper blade advances along with the chain on one side, the girder mechanism is scraped with the material on one side in the scraper blade forward edge of vertical extension, and the scraper blade promotes the material and advances to the rotatory barrel that is located feed bin bottom center, behind the material that is promoted by the scraper blade gets into rotatory barrel, before the head that reaches girder mechanism, fall from scraper mechanism discharge gate promptly, the scraper blade is along with the chain to return journey from the rear side behind the head axle. When the scraper plate outputs and guides the materials from the periphery to the center of the storage bin, the tail end of the beam mechanism carrying the scraper plate discharging mechanism revolves around the axis of the storage bin under the driving of the revolution travelling mechanism, so that the materials on the circumference of the bottom of the whole storage bin can be discharged. The rotary cylinder body and the rotary bottom plate of the central rotary mechanism rotate along with the heads of the girder mechanism and the scraper discharging mechanism, keep the relative position with the scraper discharging mechanism still and provide space for central discharging. The conical surface of the storage bin and the apron plates at the inner circumference of the conical surface can prevent materials with good fluidity from entering an annular space below the conical surface of the storage bin, and the revolution walking mechanism is prevented from being buried by the materials to cause unsmooth revolution. The girder mechanism bears the weight of the scraper discharging mechanism and the girder when providing space for the scraper discharging mechanism, and also bears the weight of materials above, so that the materials are prevented from directly entering between scrapers in the girder mechanism from the top to cause blockage of the scraper discharging mechanism. Because the scraper directly pushes the material to slide towards the discharge hole of the scraper mechanism, the power consumption is low and the advancing distance is short, compared with the spiral extrusion propulsion of a discharging auger, the energy consumption of the same discharging amount can be reduced by half, and the delivery cost is greatly reduced. For the material with better fluidity, the material can automatically flow into the space between the scrapers from the front side of the girder mechanism to form a certain collapse angle, and the material is discharged from the discharge hole of the scraper mechanism in time by the forward movement of the scrapers; because the shielding and revolution speeds of the girder mechanism are relatively slow, excessive materials can be prevented from entering between the scrapers, and the scrapers can be kept to run smoothly.
