Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The cyclone dust collector in the prior art has the defects that dust with a particle size lower than a certain particle size cannot be removed by adopting the cyclone dust collector, and the discharge standard issued by the nation can be met only by superposing expensive dust collectors such as a primary bag dust collector, an electric dust collector and the like;
to solve the above problems, the main concept adopted in this embodiment is as follows: the novel cyclone dust collector adopts a double-layer cylinder structure, an exhaust channel is arranged between the inner cylinder 1 and the outer cylinder 2, and the novel cyclone dust collector is moved to other places by removing a reverse airflow exhaust channel at the center of a cylindrical shell of the cyclone dust collector, so that the radius size of the cylindrical shell of the cyclone dust collector is reduced, the cylindrical shell with the reduced radius size is used as the cylindrical shell 12 of the inner cylinder 1, when dust-containing gas enters the inner cylinder 1 through the air inlet 4, smaller particle size and smaller mass dust are thrown to the inner wall of the cylindrical shell 12 of the inner cylinder 1 due to the increase of centrifugal force, and the dust collection effect of the cyclone dust collector is improved. The cross section area of the exhaust channel is increased as required without any limitation, so that the flow speed of the exhaust gas can be effectively reduced, and the proportion of fine particle dust taken away by the exhaust gas can be effectively reduced.
In order to better understand the above technical solutions, the following detailed description will be given with reference to the accompanying drawings and specific embodiments;
the invention provides a high-efficiency cyclone dust collector, which comprises a bracket, a cylinder body, an air inlet, an air outlet and an ash removal opening,
the cylinder body consists of an inner cylinder 1 and an outer cylinder 2,
the inner cylinder 1 comprises a seal head 11, a cylindrical shell 12 and a conical shell 13,
the outer cylinder 2 comprises a top cover 21, a cylindrical shell 22 and a conical shell 23, the ash removal opening 3 is arranged at the lower edge of the conical shell 23, the outer cylinder 2 is connected with the bracket 4,
the lowest part of the inner cylinder 1 is communicated with the lowest space of the outer cylinder 2, an exhaust passage is formed between the inner cylinder 1 and the outer cylinder 2,
the air inlet 5 penetrates through the outer cylinder 2 and is communicated with the upper part of the cylindrical shell 12 of the inner cylinder 1,
the air outlet 6 is arranged at the center of the top cover 21 of the outer cylinder 2.
According to the invention, firstly, the principle and the fundamental defects existing in the structure of the cyclone dust collector in the prior art are analyzed, and the centrifugal force of the dust in the rotating airflow, which is thrown to the cylinder wall of the dust collector cylinder, is determined by the following formula:
F＝mv 2 /r
the mass of the m-dust particles, the moving speed of the v-particles and the radius of the cylindrical shell of the r-cyclone.
As shown in fig. 7, in the prior art, if fine particle dust is required to obtain a larger centrifugal force and is thrown to the cylindrical shell wall by the centrifugal force, under the combined actions of gravity, the centripetal force of the cylindrical shell wall on dust particles and air flow, dust moves down to the lower part of the conical shell of the cyclone dust collector along the cylindrical shell wall surface in a rotating way, F is in direct proportion to the mass m, F is in direct proportion to the square of the velocity v, F is in inverse proportion to the radius r of the cylindrical shell of the cyclone dust collector, the velocity v is not easy to increase, under the condition of a certain mass m, the cross section size (cross section with an air outlet) of a reverse air flow exhaust channel in the cylindrical shell is reduced only by reducing the radius r of the cylindrical shell, and under the condition of a certain air inlet cross section of the cyclone dust inlet and a certain air pressure and a certain air flow, if the cross section (cross section with the air outlet) of the reverse air flow exhaust channel is reduced, the air flow in the cylindrical shell is increased, the air flow in the reverse air flow exhaust channel is taken away by the reverse air flow is not lost, and the dust in the cross section size of the cylindrical dust is taken away by the cylindrical dust collector, and the dust in the cylindrical dust is not taken down to the balance, and the dust in the dust is discharged by the prior art.
The invention innovatively adopts a double-layer cylinder structure, and the exhaust channel is arranged between the inner cylinder 1 and the outer cylinder 2, so that the contradiction is thoroughly solved, the radius size of the cylinder where the cyclone dust removal area is positioned can be reduced, and the sectional area of the exhaust channel can be increased without limitation.
As shown in fig. 3, unlike the prior art, the invention adopts a double-layer cylinder structure, and the exhaust channel is arranged between the inner cylinder 1 and the outer cylinder 2, the invention cancels the arrangement of the exhaust channel in the cylindrical shell 12 of the cyclone dust collector, and seals the top of the cylindrical shell 12, thus greatly reducing the radius size of the cylindrical shell 12 of the cyclone dust collector, increasing the centrifugal force suffered by dust in the inner cylinder 1, and when the gas containing dust enters the inner cylinder 1 through the air inlet 5, the dust with smaller particle size and smaller mass is thrown to the cylinder wall of the cylindrical shell 12 due to the increase of the centrifugal force, and improving the dust removing effect of the cyclone dust collector; meanwhile, a cylindrical shell 22 and a conical shell 23 with larger sizes are nested outside the cylindrical shell 12 and the conical shell 13, and the lower spaces of the nested conical shell 13 and the conical shell 23 are communicated with each other, so that the cross section area between the nested cylindrical shell 12 and the cylindrical shell 22 and the cross section area between the nested conical shell 13 and the conical shell 23 can be enlarged to the required size without any limitation, the cross section size of an exhaust channel in the central area of the cylindrical shell of the cyclone dust collector in the prior art (namely, the cross section size of an exhaust outlet of the cyclone dust collector in the prior art) can be far larger, and the exhaust channel extends upwards from the enlarged cross section to an exhaust outlet 6 with equal cross section at the upper end of the outer cylinder 2, and the gas after dust removal is exhausted; the airflow velocity of the exhaust channel is greatly reduced, so that dust with smaller size and smaller mass is left and is not pumped away, and the dust removing effect of the cyclone dust remover is further improved;
as shown in fig. 4, as a specific embodiment of the present invention, the conical housing 13 is composed of a circular truncated cone-shaped housing 14; the number of the truncated cone-shaped shells 14 is preferably three, the diameters of the truncated cone-shaped shells 14 arranged along the axial direction are sequentially reduced, and the truncated cone-shaped shells 14 are fixedly connected with the conical shell 23 through ribs;
when the dust-containing gas collides with the inner wall of the cylindrical shell 12 and moves spirally to enter the circular truncated cone-shaped shell 14 to fall, the dust-containing gas containing tiny particles enters an exhaust passage formed between the inner cylinder 1 and the outer cylinder 2 from a gap between the adjacent circular truncated cone-shaped shells 14 and is discharged upwards through the exhaust outlet 6.
As shown in fig. 5, as a specific embodiment of the present invention, the number of the air inlets 5 is three;
the gas containing dust directly enters the inner cylinder from the three air inlets 5 and rotates along the tangential direction of the inner cylinder 1 to enter the cylindrical shell 12, and compared with the independent air inlet channel in the prior art, the three air inlets 5 are adopted, so that the effect of increasing the rotation of the air flow in the cylinder is facilitated, and the dust removal efficiency is higher and more stable.
As a specific embodiment of the invention, the wall of the cylindrical shell 12 is provided with a wear-resistant layer;
because the gas containing dust moves spirally along the cylindrical shell 12 wall to the bottom of the conical shell 13, dust particles, especially high-hardness dust particles, rub against the cylindrical shell 12 wall, so that the cylindrical shell 12 wall is worn, and a wear-resistant layer is arranged on the cylindrical shell 12 wall, so that equipment overhaul and even scrapping caused by serious wear of the cylindrical shell 12 wall can be avoided, the service life of the equipment is prolonged, the maintenance cost is reduced, and the running cost of the cyclone dust collector is reduced;
in the invention, the wear-resistant layer is preferably a wear-resistant ceramic sheet or other wear-resistant metal materials, and the wear-resistant ceramic sheet is attached to the wall of the cylindrical shell 12 in specific implementation, so that the wear of the wall of the cylindrical shell 12 is reduced in dust removal.
The specific working procedure is as follows:
as shown in fig. 3, the dust-containing gas enters the cylindrical shell 12 of the inner cylinder 1 from the air inlet along the tangential direction of the cylindrical shell 12 of the inner cylinder 1 and rotates at a high speed to perform circular motion, most of dust particles in the air flow are thrown to the inner wall of the cylindrical shell 12 by a great centrifugal force, and under the combined action of the reaction force, gravity and air flow attraction of the inner wall, the dust particles do spiral motion and fall into the lower part of the conical shell 13 of the inner cylinder 1, and the dust particles suspended in a finer space are sucked by the air flow, firstly move along the space of the communication part between the lower part of the conical shell 13 of the inner cylinder 1 and the lower part of the conical shell 23 of the outer cylinder 2, then move upwards to the space formed between the cylindrical shell 12 of the inner cylinder 1 and the cylindrical shell 22 of the outer cylinder 2, and finally are discharged from the uppermost exhaust outlet.
As shown in fig. 4, the specific working procedure is substantially the same as described above, except that the dust particles suspended in the finer space are moved by the air flow sucking portion along the space of the communicating portion of the lower portion of the circular table-shaped housing 14 of the inner cylinder 1 and the lower portion of the conical housing 13 of the outer cylinder 2, and partially along the gap between the circular plurality of table-shaped housings 14, and both of these air flows flow toward the space formed between the cylindrical housing 12 of the inner cylinder 1 and the cylindrical housing 22 of the outer cylinder 2, and finally discharged from the uppermost exhaust port.
In summary, the innovative structure of the invention can make the radius of the inner cylinder of the cyclone dust removing area of the cyclone dust remover smaller than that of the product in the prior art, so that the dust particles are subjected to larger centrifugal force to make finer dust particles fall to the lowest part of the inner cylinder 1, the dust removing efficiency is improved, and the cross section area of the exhaust channel is increased to an ideal degree without limitation, thereby reducing the airflow velocity, reducing the proportion of tiny particles carried away by the airflow, and further improving the dust removing efficiency.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
