TECHNICAL FIELD
[0001] The present application relates to the technical field of tobacco processing equipment, in particular to a tobacco purification treatment device with filter element assembly. BACKGROUND
[0002] In the tobacco processing industry, tobacco raw materials must undergo strict pretreatment before entering subsequent fine processing links such as cutting and rolling, and the screening link is a crucial step. Traditional tobacco screening methods mostly rely on simple mechanical screening equipment. In actual operation, workers pour tobacco raw materials onto the screen, and then shake or use a simple mechanical vibration device to move the raw materials on the screen to separate impurities from qualified tobacco.
[0003] This traditional screening method has extremely low screening efficiency and cannot meet the needs of modern large-scale industrialized tobacco production. Due to the lack of precise control and efficient power transmission mechanism in the screening process, the tobacco raw materials are not sufficiently turned over on the screen, resulting in incomplete screening and a large amount of impurities and tobacco particles that do not meet quality requirements remaining, which seriously affects the quality stability of subsequent processed products.
[0004] Secondly, during the screening process, the mutual friction of tobacco raw materials and the collision with the screen will generate a large amount of dust that diffuses in the working environment. These dusts not only contain small particles of tobacco, but also may contain other impurities, which can cause serious harm to the respiratory system of the operator. Long-term exposure to such an environment can cause health problems such as respiratory diseases and lung diseases. Moreover, if these dusts adhere to the tobacco raw materials, they will further affect the purity and taste of the tobacco, reducing the quality of the product.

[0022] Reference Figure 1 , Figure 3As shown in one embodiment: the tobacco purification device includes a fixed frame 1, which is used as a base support component to provide a stable structure for the entire device, a fixed cavity 2 on the fixed frame 1 cooperates with a screening cavity 3, a certain gap is maintained between the inner wall of the fixed cavity 2 and the outer wall of the screening cavity 3, so that the screening cavity 3 can move up and down smoothly in the fixed cavity 2, and at the same time, it also limits the moving direction of the screening cavity 3 to prevent it from deviating or shaking, ensuring the stability of the screening process, a screening mechanism 4 for vibrating and screening tobacco raw materials is arranged in the screening cavity 3, and a screening net 5 inside the screening cavity 3 is firmly connected to the middle position of the screening cavity 3 by welding, which ensures the accuracy and effect of screening, and effectively separates the impurities from the qualified part of the tobacco raw materials, so that the impurities fall into the collecting hopper 6 below through the screening net 5, and the collecting hopper 6 and the bottom of the fixed cavity 2 are connected in a detachable manner, which not only ensures the stability of the collecting hopper 6, but also ensures that the screened impurities can be completely collected without leakage, facilitating subsequent cleaning work, and a vibrating mechanism 7 is installed on the fixed frame 1 and connected to the screening cavity 3 through mechanical transmission, which can stably transmit the vibration force generated by the vibrating mechanism 7 to the screening cavity 3, so that the screening cavity 3 vibrates regularly up and down, promoting the tobacco raw materials to move fully on the screening net 5 and improving the screening efficiency.
[0023] The implementation principle of the above embodiment is that the vibration force generated by the vibrating mechanism 7 is transmitted to the screening cavity 3, so that the screening cavity 3 moves up and down in the fixed cavity 2, and since the screening net 5 is fixed in the screening cavity 3, the tobacco raw materials continuously roll and jump on the screening net 5 under the vibration of the screening cavity 3, thereby realizing the separation of impurities and qualified tobacco raw materials, and the separated impurities fall into the collecting hopper 6 through the screening net 5 under the action of gravity, achieving the purpose of preliminary screening of tobacco raw materials.
[0024] Referring to Figure 1 , Figure 3 As shown in one embodiment: a feeding port 8 is formed on one side of the screening cavity 3, the shape and size of the feeding port 8 are designed according to actual production needs, facilitating the addition of tobacco raw materials, a closed baffle 9 is installed on the screening cavity 3 through the detachable connection of the clamping groove, which can tightly close the feeding port 8 to prevent tobacco raw materials from overflowing and dust from escaping during the screening process, and a handle 10 is installed on the closed baffle 9 to facilitate the opening and closing of the closed baffle 9 by the operator, improving the convenience of operation, and the handle 10 is fixedly connected to the closed baffle 9.
[0025] The implementation principle of the above embodiment is that when the tobacco raw material is added, the operator holds the pull handle 10 to open the closing baffle 9, pours the tobacco raw material into the screening cavity 3 from the feeding port 8, and then closes the closing baffle 9. The detachable connection mode of the closing baffle 9 and the screening cavity 3 ensures the sealing of the closing, avoids the loss of raw materials and environmental pollution caused by the unsealed feeding port 8 during the screening process, and the setting of the pull handle 10 enables the operator to easily and quickly open and close the closing baffle 9, thereby improving the operation efficiency of the entire device, reducing material waste and environmental impact during production, and ensuring the normal operation and screening effect of the tobacco purification treatment device.
[0026] Referring to Figure 2 , Figure 3 , Figure 4 An embodiment shown in the figure is that the fixed seat 11 is installed on the fixed frame 1 to provide stable support for the driving motor 12, so as to ensure that the driving motor 12 will not be displaced during operation. The driving motor 12 is fixed on the fixed seat 11 through bolt connection, the output end thereof is connected with the rotating shaft 13 through key connection or shaft coupling, so as to ensure stable transmission of power. The rotating shaft 13 is horizontally installed, the rotating cams 14 at both ends thereof are fixed on the rotating shaft 13 through interference fit or key connection, the protruding part of the rotating cam 14 is in close contact with the sliding plates 16 in the sliding grooves 15 on both sides of the screening cavity 3, the sliding plates 16 are fixed on the two side walls of the screening cavity 3 through welding or bolt connection, and the cooperation clearance between the sliding plates 16 and the sliding grooves 15 is moderate, so as to ensure smooth up-and-down sliding of the sliding plates 16 in the sliding grooves 15, and limit the movement direction of the screening cavity 3, so that the screening cavity 3 can only vibrate up and down in the vertical direction.
[0027] The implementation principle of the above embodiment is that when the driving motor 12 is started, the rotating shaft 13 is driven to rotate, and the rotating cam 14 on the rotating shaft 13 rotates accordingly. Since the protruding part of the rotating cam 14 is in contact with the sliding plate 16, the protruding part of the rotating cam 14 will periodically push the sliding plate 16 to slide upward during rotation. When the protruding part leaves the sliding plate 16, the screening cavity 3 falls back under the action of its own gravity, so as to realize the up-and-down vibration of the screening cavity 3. The design of the vibrating mechanism 7 converts the rotary motion of the driving motor 12 into the up-and-down linear vibration of the screening cavity 3 through the precise connection and cooperation between the components, so that the tobacco raw material can be fully turned and screened on the screening net 5, thereby improving the screening efficiency and quality.
[0028] Referring to Figure 2 , Figure 3 , Figure 4An embodiment shown is that the top of the screening cavity 3 is fixed with a dust collecting cavity 17 through welding or bolt connection, the dust collecting cavity 17 provides mounting space for the filter core assembly 18, and forms a relatively closed dust collecting area at the same time, the filter cylinder 19 in the filter core assembly 18 is placed in the dust collecting cavity 17, the filter layer 20 on the circumferential side of the filter cylinder 19 can be filter paper, filter screen or other high-efficiency filter material, which is fixed on the outer circumference of the filter cylinder 19 through pasting, winding or inlaying and the like, so as to ensure good filtering effect on dust, the air outlet passage 21 on the inner side of the filter cylinder 19 is communicated with the top of the dust collecting cavity 17, so as to ensure that the filtered air can be smoothly discharged, the suction fan 22 is installed on the top of the dust collecting cavity 17 through bolt connection or a hanger, the air outlet of the suction fan 22 is connected with an external ventilation pipeline, so as to discharge clean air, the air inlet holes 23 on both sides in the screening cavity 3 are uniformly distributed and communicated with the inside of the dust collecting cavity 17, so that the dust-containing air in the screening cavity 3 can enter the dust collecting cavity 17 under the action of the suction fan 22.
[0029] The implementation principle of the above embodiment is that in the process of tobacco screening, the suction fan 22 is started, and a negative pressure environment is formed in the dust collecting cavity 17, at this time, the air in the screening cavity 3 carries dust and enters the dust collecting cavity 17 from the air inlet holes 23 under the action of pressure difference, when the dust-containing air passes through the filter layer 20 of the filter core assembly 18, the dust is intercepted and adsorbed by the filter layer 20, and the clean air is discharged from the dust collecting cavity 17 through the air outlet passage 21 on the inner side of the filter cylinder 19, this dust collecting and purifying structure effectively collects and purifies the dust generated in the screening process through the reasonable connection and cooperation of various components, reduces the pollution of dust to the working environment, protects the health of the operating personnel, avoids the secondary pollution of dust to the tobacco raw materials, improves the purity of tobacco and product quality, the close connection between various components ensures the sealing and stability of the entire dust collecting and purifying process, improves the dust purifying efficiency, and provides strong support for the environmental protection performance of the tobacco purifying treatment device.
[0030] Referring to Figure 2 An embodiment shown is that the transparent observation plate 24 is fixedly installed at one end of the screening cavity 3 through a clamping groove or sealing glue and the like, the observation plate 24 can be made of glass, organic glass or other transparent materials, the connection between the observation plate 24 and the screening cavity 3 ensures good sealing property, prevents dust from entering the gap between the observation plate 24 and the screening cavity 3 and affecting the observation effect, and the observation plate 24 is selected to be located at the end far away from the closed baffle 9, so that the operating personnel can clearly observe the screening condition of the tobacco raw materials in the screening cavity 3.
[0031] The implementation principle of the above embodiment is that during the operation of the tobacco purification treatment device, the operator can observe the distribution of the tobacco raw material in the screening cavity 3, the screening progress, and whether there is an abnormality such as blockage through the observation plate 24 in real time. Since the observation plate 24 is closely connected with the screening cavity 3 and has good sealing performance, the accuracy and clarity of observation are ensured, and at the same time, any interference to the screening process is avoided. According to the observed situation, the operator can timely adjust the operation parameters of the equipment, such as the vibration frequency of the vibration mechanism 7, the air power of the suction fan 22, or perform necessary maintenance and cleaning on the equipment, so that the equipment is always in the best operation state, the operation convenience and reliability of the equipment are improved, the production interruption and product quality problems caused by equipment failure or improper operation parameters are reduced, and a powerful guarantee is provided for the efficient and stable operation of the tobacco purification treatment device.
[0032] The working principle of the device is that when the tobacco purification treatment device of the utility model is working, first, the tobacco raw material is added to the screening cavity 3 from the feeding port 8, after the feeding port 8 is closed, the vibration mechanism 7 is started, the driving motor 12 drives the rotating cam 14 to rotate, the screening cavity 3 is vibrated up and down, the tobacco raw material is preliminarily screened on the screening net 5, and the impurities fall into the collecting hopper 6. At the same time, the suction fan 22 works, the dust-containing air in the screening cavity 3 is sucked into the dust collecting cavity 17, and clean air is discharged after being filtered and purified by the filter core assembly 18. In the whole process, the operator can observe the screening condition through the observation plate 24 at any time, and adjust the equipment operation parameters according to the actual situation, such as the rotating speed of the driving motor 12, the air power of the suction fan 22, etc., so as to achieve the best screening and purification effect.
