Abstract
The utility model discloses a pipe tobacco steeping cell lower cover filter screen, including frame and filter screen (3), the frame includes outer lane (1) and inner circle (2), and outer lane and inner circle pass through splice bar (4) and connect structure as an organic whole, and filter screen (3) are punched by the metal sheet and are made, filter screen (3) distribution in outer lane, space that inner circle and splice bar formed, the utility model discloses cone filter screen (5) that still circle including fixed, the bottom surface diameter of cone filter screen is the same with the diameter of inner circle, and inner circle, filter screen (3) and cone are strained net shape and are become a circular cone space, have placed the tobacco tar adsorbent in the circular cone space. The utility model discloses a cone filter screen and tobacco tar adsorbent have alleviateed the tobacco tar scaling on the equipment inner wall effectively, have prolonged the clearance service equipment cycle, and be long when having reduced clean -up equipment, practices thrift manpower and materials, improve flooding medium carbon dioxide's purity through the tobacco tar adsorbent, alleviateed the scaling of technology pump and pipeline, improved equipment life.
Description
Technical field
This utility model relates to tobacco leaf production equipment technical field, is specifically related to a kind of tobacco shred macerator lower cover filter screen.
Background technology
Tobacco shred macerator filter screen is the critical component of carbon dioxide expanded cut tobacco production line cold side equipment in tobacco leaf production, directly influence the dipping effect of tobacco shred, especially the lower cover filter screen of macerator, in the prior art, tobacco shred macerator filter screen is made up of framework and filter screen two parts, and framework is made up of inside and outside two rustless steel annulus.The effect of filter screen is filter tobacco, stops tobacco shred to enter carbon dioxide conduit and storage tank, plays the filtration of a physics.But, in actual production, liquid carbon dioxide is after tobacco shred immersion, ree-oil in tobacco shred becomes branch to be back in pipeline, technique pump and storage tank along with carbon dioxide, time length, the inwall of technique pump and storage tank can precipitate the ree-oil that thick layer is thick, affect the service life of technique pump；Although the pump housing and storage tank all can be cleared up by workshop every year, but this scale removal process length consuming time, difficulty are relatively big, waste time and energy.
Summary of the invention
The purpose of this utility model is in that to provide a kind of tobacco shred macerator lower cover filter screen, and this filter screen can alleviate the ree-oil dirt on equipment inner wall, extends cleaning and safeguards equipment periodic, reduces cleaning equipment duration, use manpower and material resources sparingly, and the service life of extension device.
For achieving the above object, a kind of tobacco shred macerator lower cover filter screen, including framework and filter screen, described framework includes outer ring and inner ring, described outer ring and inner ring connect as one structure by dowel, described filter screen is made up of metallic plate punching, described filter screen is distributed in the space that outer ring, inner ring and dowel are formed, also include the conical sieve being fixed on inner ring, the basal diameter of described conical sieve is identical with the diameter of inner ring, described inner ring, filter screen and conical sieve form a conical space, are placed with ree-oil adsorbent in described conical space.
Preferably, the cone angle of described conical sieve is 60 °～120 °.
Preferably, the mesh aperture of described filter screen is 0.5mm.
Preferably, the quantity of described dowel at least four.
Compared with prior art, this utility model passes through to increase the conical space that conical sieve is formed and the ree-oil adsorbent placed in conical space on the basis of original inner ring filter screen, thus the ree-oil dirty effectively alleviated on equipment inner wall, extend cleaning and safeguard equipment periodic, decrease cleaning equipment duration, use manpower and material resources sparingly；It addition, improve the purity of steeping medium carbon dioxide by ree-oil adsorbent, alleviate the dirty of technique pump and pipeline, improve service life of equipment.This utility model is reasonable in design, simple in construction, be prone to processing, be suitable to promote the use of at tobacco business.

Fig. 2 is front view of the present utility model；
In figure: 1, outer ring, 2, inner ring, 3, filter screen, 4, dowel, 5, conical sieve.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of tobacco shred macerator lower cover filter screen, including framework and filter screen, described framework includes outer ring 1 and inner ring 2, described outer ring 1 and inner ring 2 connect as one structure by dowel 4, described filter screen 3 is made up of metallic plate punching, described filter screen 3 is distributed in outer ring 1, in the space that inner ring 2 and dowel 4 are formed, described tobacco shred macerator lower cover filter screen also includes the conical sieve 5 being fixed on inner ring 2, the basal diameter of described conical sieve 5 is identical with the diameter of inner ring 2, described inner ring 2, filter screen 3 and conical sieve 5 form a conical space, ree-oil adsorbent it is placed with in described conical space.
In order to make ree-oil adsorbent reach bigger adsorption space, the cone angle of described conical sieve 5 is 60 °～120 °.
In order to ensure the uniformity of mesh and improve the percent of pass of tobacco shred, the mesh aperture of described filter screen 3 is 0.5mm.
In order to make the intensity that this utility model bears higher, the quantity at least four of described dowel 4.
During expanded cut tobacco produces, macerator is used for tobacco shred immersion, and main part is made up of cylinder and the upper and lower covers being connected with pipeline, and steeping medium is the liquid carbon dioxide of high pressure.During dipping process, macerator upper and lower covers is fastened, the liquid carbon dioxide pipeline by being connected with lower cover, enters macerator then through this utility model and impregnates, and this utility model is fixed on the tobacco filler place of tobacco shred macerator by inner ring 2；After having impregnated, liquid carbon dioxide flows back into pipeline by this utility model, now, the part ree-oil in ree-oil adsorbent meeting absorbing carbon dioxide, thus improving the degree of purity of liquid carbon dioxide, promote quality of tobacco shreds, alleviate the ree-oil dirty of pipeline, technique pump and storage tank, extend the service life of technique pump and the cycle of cleaning maintenance equipment, use manpower and material resources sparingly, decrease cleaning equipment duration, offer convenience for the cleaning technology pump pump housing and storage tank.
