Description
Technical field:
The present invention relates to a kind of granule materials dense phase loading device, relate in particular to the dense phase loading of petroleum chemical industry consersion unit catalyst granules.
Background technology:
The filling work of the filling of granule materials, especially catalyst granules more and more comes into one's own in its relevant field.The Catalyst packing technology that generally adopts both at home and abroad at present is a kind of dense phase loading technology, can bring into play to greatest extent the performance of catalyst in reactor.Existing granule materials dense phase loading equipment generally all comprises a distributing device and its actuating device, and this distributing device or be ellipsoid spare or be plane plectane or wing plate pivots under the actuating device drive, and material is evenly spread out.Its purpose all is granule materials to be shed into some donuts pile up layer by layer in cylinder type feed bin or reactor, reaches as far as possible the purpose of even filling.
CN101168409 relates to a kind of fin plate type stock distributor, is made of motor or pneumatic rotary drive device, material seeding dish and mounting bracket.Be provided with the material seeding dish that one to two horizontally rotates at axle, rotating driving device and material seeding dish all are fixed on the bottom of charging hopper by mounting bracket.The shape of material seeding dish is oval or avette, and ratio of semi-minor axis length is 1: 0.35-0.99.The stock distributor device is fixed in the vertical vessel top during work, and actuating device drives the material seeding disc spins, and granule materials is sowed at internal tank.
CN101830354B discloses a kind of granule materials filling even distribution device, is comprised of barrel, actuating device and distributing device etc.Actuating device is motor or air motor, is installed on barrel inside.Distributing device is sphere, ellipse or spherical seal head shape, has the bar hole of certain planform on it.During work this granule materials filling device is installed on container top, granule materials is thrown away from cylindrical void by distributing device through the distributing device of rotation, falls into container along certain parabolic path, finishes the filling process.
As above existing catalyst dense phase loading device all is to shed the purpose that material reaches cloth and dense phase loading by the rotation of distributing device, in actual mechanical process, it is inhomogeneous that the charge level height often appears, middle low high situation all around, along with charge level height in the filling process progressively raises, the gradually raising of distributing device rotating speed, this kind phenomenon is particularly evident.The general employing reduced rotating speed material shed to pit on the engineering, proceeds after the charge level correction is smooth, so repeatedly.So both affect filling efficient, also affected the homogeneity of loading density, thereby affected the effect of whole dense phase loading.
Summary of the invention:
The objective of the invention is: propose a kind of catalyst dense phase loading device, can overcome the existing apparatus deficiency, realize the even filling of catalyst, improve the planeness of charge level in the filling process, reduce the manual intervention in the filling process, Effective Raise material filling density reduces the percentage of damage of catalyst in the filling process.
The technical solution used in the present invention is: a kind of catalyst dense phase loading device, comprise barrel, actuating device, transmission device and distributing device, described actuating device is installed on the barrel top, distributing device is installed on the barrel bottom, the two connects by the transmission device that is installed on barrel inside, it is characterized in that described distributing device is the conical disk shape, have change aperture bar hole on the described distributing device.The aperture of described bar hole by the vertex of a cone to around diminish gradually, the aperture rate of change in hole is relevant with the cloth tray tapering, and described bar hole has at least one partly to run through at the distributing device vertex of a cone, prevents throwing away baffle plate along being equipped with on the distributing device simultaneously.
Its workflow is: this dense phase loading device is installed on the consersion unit top, starts the rotation of driven by motor distributing device; Catalyst transport relies on gravity to move downward in barrel, enters into the distributing device of rotation, then sows away from the cylindrical void that distributing device is offered, and the variation of the cylindrical void that the vertex of a cone partly runs through and cylindrical void aperture size all helps evenly sowing of material.The anti-baffle plate that throws away that the distributing device top arranges can prevent that material throws away when the distributing device rotating speed is higher above distributing device, cause material to pile up in the charge cask marginal portion.After material is sowed out, do the movement of falling object along parabolic path, evenly scatter at reaction container bottom, pile up layer by layer, charge level progressively raises, and realizes even dense phase loading.
The present invention has following beneficial effect: apparatus structure is compact, is easy to carrying and installation, and is simple to operate.Can significantly improve material filling speed and charge level planeness, the Effective Raise loading density reduces the percentage of damage of particle in the filling process, realizes the dense phase loading of real meaning.
