Description
Technical field
The present invention relates to a kind of pitch filter, relate in particular to a kind of using rubber powder of waste tire modified pitch filter of effective removing metal impurities.
Background technology
The using rubber powder of waste tire modified pitch is to be a kind of novel road road surfacing material that raw material is processed with matrix pitch and using rubber powder of waste tire.Owing to have the Pavement Performance of raising and environmental protection characteristic, obtain increasingly extensive application.But because of its raw material adopts using rubber powder of waste tire; Carry along pipeline, equipment in addition, make metal impurities and nonmetallic inclusions such as containing a certain amount of steel wire in small, broken bits, welding slag in this modified pitch, especially metal impurities have certain degree of hardness; Like untimely removing; Produce and application process in very easily cause the plug, card failure of pump, colloid mill, valve and other equipment so that damage, stop production to overhaul, still more exchange device all can cause human and material resources, time loss, reduces production efficiency.For this reason, personnel have taked corresponding measure in the industry, promptly carry out the impurity filtering through filter.Existing using rubber powder of waste tire modified pitch filter mainly adopts a barrel formula filter, and the outlet of pitch import and pitch is set respectively on the bucket wall of filter staving both sides, and the tubbiness screen pack is set in bucket; For preventing when material passes through screen pack; Mesh is too for a short time to cause instantaneous obstruction, and influence is produced, and screen pack generally adopts the mesh of moderate size; Therefore can only hold back larger particles impurity, the metal impurities that particle diameter is very little can't filtering.In reality is produced; The pressure that is got into the using rubber powder of waste tire modified pitch of filter staving by the production system transfer pipeline reaches more than the 0.3MPa; Flow velocity is very fast, and modified pitch material time of staying in filter is very short, and metal impurities also can not be realized precipitate and separate; Can continue to flow with the modified pitch material, retain wherein.
For removing metal impurities, also appear at the way that permanent magnet is set on the filter staving in the industry at present, remove metal impurities with absorption; But still there is open defect in this filter and since permanent magnet can be very soon in the production environment of heat state demagnetization, when demagnetizing to a certain degree; Permanent magnet magnetic weakens; The a large amount of metal impurities that can unexpected release have adsorbed make it get into production system, and the plug, card failure that still cause pump, colloid mill, valve and other equipment are so that damage.
In sum, how effectively to remove metal impurities, become the problem of being badly in need of solution in the industry.
Summary of the invention
Main purpose of the present invention is to above-mentioned technical problem; A kind of using rubber powder of waste tire modified pitch filter of effective removing metal impurities is provided; Production and application scenario at the using rubber powder of waste tire modified pitch can prevent equipment fault and damage, enhance productivity.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of using rubber powder of waste tire modified pitch filter of effective removing metal impurities; Comprise the filter staving; Be arranged on the magnet on the filter staving, the outlet of pitch import and pitch is set respectively on the bucket wall of filter staving both sides, in the filter staving, be provided with filter screen and collect basket; It is characterized in that said filter staving top is provided with dismantled and assembled bung; In the filter staving, export the vertical baffle that the filter staving is divided into successively pitch filter chamber and pitch output chamber over against pitch import setting by pitch import to pitch, the dual-side of said baffle and base are sealedly and fixedly connected respectively in filter staving corresponding bucket wall and bottom surface; It is that lining is contained in the said pitch filter chamber and the closed basket that is communicated with the pitch import that said filter screen is collected basket, is made up of the end bucket of splendid attire impurity and the filtering screen that connects on it, and the filtering screen top is higher than pitch import upper edge; The baffle top is along exceeding the filtering screen top and possessing distance setting with said bung, and said magnet is an electromagnet, is arranged on the outside, filter staving bottom surface.
Spacing between the outlet of said baffle and pitch equates with the pitch inlet diameter; Baffle top is along the height that exceeds the filtering screen top 1.5 times more than or equal to the pitch inlet diameter, and edge, baffle top equates with the pitch inlet diameter with distance between bung.
On all buckets of said filter staving ring wall, be provided with the insulation jacket of circulation heat medium.
Said filter screen is collected basket and is provided with carrying handle, and the carrying handle top compresses bung, and bucket of the said end is connected with filtering screen is dismantled and assembled.
The invention has the beneficial effects as follows: owing in the staving of using rubber powder of waste tire modified pitch filter, be provided with baffle; In filter staving bottom surface arranged outside electromagnet, and adopted the filter screen of band end bucket to collect basket, like this; In filter process; The modified pitch material that makes the pressure that gets into by the pitch import reach 0.3MPa receive with its over against baffle and the filter screen brute force of collecting basket stop that build-up of pressure slows down, and form sinuous flow; Created abundant chance and made material realize contacting with electromagnet, made metal impurities be adsorbed on filter screen fully and collect the bucket bottom, the end of basket than large tracts of land, more time.Because the magnetic of electromagnet is controlled, no demagnetization problem, thus effectively remove metal impurities, improved the pure degree of using rubber powder of waste tire modified pitch, especially in its production and application scenario, can prevent equipment fault and damage, enhance productivity.
