Description

Technical Field

[0001] The invention relates to the technical field of flash steamed shredded stem puffing, and in particular to a shredded stem puffing discharging device with a self-loosening function. Background Art

[0002] The SH84 flash-steamed shredded stem puffing device for silk thread making has been in use for many years. The current status and operating conditions of the equipment are poor. The coatings on the inner wall of the discharge cover and the distributor are peeling and damaged, resulting in steam leakage, material adhesion to the inner wall, and material agglomeration during equipment operation, which affects the quality of shredded stems and the stability of the moisture content of the discharge from the subsequent drying equipment (fluidized bed dryer). The main problems are as follows:

[0003] (1) The coating on the inner and outer walls of the distributor falls off seriously. When the equipment is running, the material cannot slide down smoothly and is easily adhered to the wall of the equipment cavity, causing the material to agglomerate and making daily cleaning inconvenient, affecting the quality of the tobacco and the stability of the moisture content of the discharge material in the later stage (fluidized bed).

[0004] (2) The discharge hood is damaged and the inner wall coating has fallen off. The inner wall is very easy to adhere to the material, which poses a risk of steam leakage and requires a high frequency of daily maintenance.

[0005] The above problems have an adverse impact on the daily maintenance and operating parameters of the equipment, restricting the further improvement of the quality control level of the shredded stem drying process. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a shredded stem puffing discharging device with a self-loosening function. By optimizing the design of the divider and the loosening device, the problems of material adhesion, agglomeration and incomplete steam-material separation in the existing equipment are effectively solved, thereby improving the shredded stem quality, reducing maintenance costs, enhancing the operating efficiency and reliability of the equipment, and ensuring the stability of the moisture content of the discharging material of the subsequent drying equipment.

[0007] The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0008] A shredded stem puffing discharging device with a self-loosening function, the device being installed at the discharging end of a flash-steamed shredded stem puffing device, comprising:

[0009] A tangential distributor is arranged in the discharge cover and connected to the mounting seat inside the discharge cover. The feed pipe of the tangential distributor is connected to the expansion pipe of the stem shredded puffing device. The material can enter the tangential distributor tangentially through the feed pipe. The upper part of the cylinder of the tangential distributor is provided with an exhaust port for exhausting water vapor to separate the material from the water vapor.

[0010] The loosening device is arranged at the discharge end of the tangential distributor. The loosening device includes a discharge hopper and multiple groups of loosening rollers with rake nails. The loosening rollers are driven to rotate by a driving device to loosen the materials.

[0011] Preferably, in the above technical solution, the cylinder body of the tangential distributor is a cylindrical structure, and the feed pipe is arranged along the tangent direction of the cylindrical structure, so that the materials enter the tangential distributor tangentially under the action of steam thrust.

[0012] Preferably, in the above technical solution, the cylinder body of the tangential distributor adopts an involute arc to reduce the friction between the materials and the inner wall of the distributor, so that the materials can fall more smoothly.

[0013] Preferably, in the above technical solution, the cross-sectional dimension of the feed pipe is smaller than that of the cylinder body of the tangential distributor, so that the materials and water vapor maintain a high movement speed in the feed pipe. After entering the cylinder body of the distributor, the wind speed decreases, and the materials with a larger density fall under the action of gravity, while the water vapor with a smaller density is discharged through the exhaust port under the action of the moisture exhaust fan.

[0014] Preferably, in the above technical solution, the driving device includes a sprocket, a chain and a motor. There are three groups of loosening rollers. One group of loosening rollers is directly driven by the motor to rotate, and the other two groups of loosening rollers are driven by the loosening roller directly driven by the sprocket and the chain.

[0015] Preferably, in the above technical solution, rake nails are arranged on the loosening rollers, and the rake nails are arranged in a non-linear manner, so that when loosening the agglomerated materials, the rake nails can strike the agglomerated materials one by one, avoiding the materials being thrown up or adhered by the rake nails.

[0016] Preferably, in the above technical solution, the rake nails are arranged in a spiral dislocation manner.

[0017] Preferably, in the above technical solution, the loosening device is fixed on the body support of the cut tobacco puffing device.

[0018] The above technical solution of the present invention has the following beneficial effects:

[0019] The cut tobacco puffing discharging device with self-loosening function of the present invention adopts an involute arc design for the tangential distributor, which, in combination with the tangential feeding method, significantly reduces the friction between the material and the inner wall of the distributor, reduces the adhesion and agglomeration of the material, and at the same time realizes the effective separation of the material and water vapor. In the loosening device, three loosening rollers with rake nails work together through direct motor connection drive and sprocket chain drive to individually strike and loosen the agglomerated material, avoiding the throwing up and adhesion of the material, and further improving the dispersion effect of the material. In addition, the overall structure of the device is simple, with low cost, reliable operation and convenient maintenance, significantly reducing the daily maintenance frequency and operation cost of the equipment, effectively improving the quality of cut tobacco and the stability of the moisture content of the discharged material of the subsequent drying equipment, and enhancing the quality control level of the entire cut tobacco drying process.

[0023] Now, various exemplary embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements, numerical expressions and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0024] Unless otherwise specified, the experimental methods used in the following embodiments are all conventional methods. The materials and reagents used, unless otherwise specified, can all be obtained from commercial channels. The equipment used in the experiments, unless otherwise specified, are all well-known to those skilled in the art.

[0025] A cut tobacco puffing discharging device with self-loosening function, the device is installed at the discharging end of a flash cut tobacco puffing device, and includes:

[0026] The tangential distributor 3 is arranged inside the discharge hood 1 and connected to the internal mounting seat of the discharge hood 1. The feed pipe 2 of the tangential distributor 3 is connected to the expansion pipe of the cut tobacco puffing device. The material can enter the tangential distributor 3 tangentially through the feed pipe 2. An exhaust port is provided at the upper part of the cylinder body of the tangential distributor 3 to discharge water vapor to achieve the separation of the material and the water vapor. Further, the cylinder body of the tangential distributor 3 is of a cylindrical structure, and the feed pipe 2 is arranged along the tangent direction of the cylindrical structure, so that the material enters the tangential distributor 3 tangentially under the action of the steam thrust. The cylinder body of the tangential distributor 3 adopts an involute arc to reduce the friction between the material and the inner wall of the distributor, so that the material can fall more smoothly. The cross-sectional dimension of the feed pipe 2 is smaller than the cross-sectional dimension of the cylinder body of the tangential distributor 3, so that the material and the water vapor maintain a relatively high moving speed in the feed pipe. After entering the cylinder body of the distributor, the wind speed decreases, and the material with a larger density falls under the action of gravity, while the water vapor with a smaller density is discharged through the exhaust port under the action of the moisture exhaust fan.

[0027] The loosening device is arranged at the discharge end of the tangential distributor 3. The loosening device includes a discharge hopper 5 and multiple groups of loosening rollers 6 with rake nails. The loosening device is fixed on the body support 4 of the cut tobacco puffing device. The loosening rollers 6 are driven to rotate by a driving device to loosen the material. Further, the driving device includes a sprocket 7, a chain 8 and a motor 10. There are three groups of loosening rollers 6. One group of loosening rollers 6 is directly driven by the motor 10 to rotate, and the other two groups of loosening rollers 6 are driven by the loosening rollers 6 directly driven through the sprocket 7 and the chain 8. Rake nails are arranged on the loosening rollers 6, and the rake nails are arranged in a non-linear arrangement, so that when loosening the agglomerated material, the rake nails can strike the agglomerated material one by one, avoiding the material being thrown up or adhered by the rake nails. Preferably, the rake nails are arranged in a spiral staggered arrangement. In addition, a bearing 9 is also provided. The bearing 9 is used to support the rotating shaft of the loosening roller 6, reduce the friction and wear during the rotation process, thereby prolong the service life of the equipment and ensure its operating reliability.

[0028] The working process is as follows:

[0029] (1) The material enters the tangential distributor:

[0030] After the flash cut tobacco puffing device is normally started, the puffed material enters the tangential distributor 3 tangentially through the feed pipe 2 from the expansion pipe of the flash cut tobacco puffing device under the action of the steam thrust. The feed pipe 2 is arranged along the tangent direction of the cylinder body of the tangential distributor 3, so that the material can enter the tangential distributor 3 tangentially.

[0031] After the material enters the tangential distributor 3, under the action of the inertia and gravity of the air flow, it rotates and descends along the inner wall of the cylinder body of the tangential distributor 3.

[0032] (2) Separation of steam and material:

[0033] An exhaust port is provided at the upper part of the cylinder body of the tangential material distributor 3. Under the action of the moisture exhaust fan, the less dense water vapor is discharged from the material distributor through the exhaust port, thereby realizing the separation of the material from the water vapor.

[0034] During the rotation and downward movement of the material on the inner wall of the tangential material distributor 3, the movement direction of the material changes, reducing the possibility of material agglomeration.

[0035] (3) Loose treatment of materials:

[0036] The whole loose device is fixed on the body bracket 4 of the cut tobacco puffing device to ensure the stable operation of the device. The loose device can further reduce the occurrence of agglomeration.

[0037] The separated material enters the loose device from the discharge end of the tangential material distributor 3. The loose device is installed below the tangential material distributor 3.

[0038] The loose roller 6 in the loose device is driven by the motor 10. One group of loose rollers is directly driven by the motor 10, and the other two groups of loose rollers 6 are driven by the sprocket 7 and the chain 8. The agglomerated material is struck by the three groups of rotating loose rollers 6 to achieve the purpose of loosening.

[0039] (5) Discharge of materials:

[0040] The material after loose treatment is discharged from the discharge hopper 5 and enters the subsequent processing process.

[0041] Through the above design and working process, the cut tobacco puffing discharge device with self-loosening function of the present invention can solve the problems existing in the current equipment, effectively reduce the phenomenon of material adhering to the inner wall of the equipment, reduce the frequency of daily maintenance; through the material loose device, the phenomenon of material agglomeration can be effectively avoided, reduce the fluctuation of the discharge moisture of the subsequent drying equipment, and improve the stability of the discharge moisture. Improve the processing quality of the work-in-process; low cost and reliable work.

[0042] Although the present invention has been disclosed above with embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different selections and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is defined by the claims and their equivalent forms.
