Description

Technical Field

[0001] The utility model relates to the field of tobacco production, and more specifically to a self-cleaning filtering device for a loose tobacco moisture regeneration outlet. Background Art

[0002] In the tobacco processing industry, loosening and rehumidification devices are widely used in the recovery and humidification process of tobacco leaves. Tobacco can only be used for subsequent processing steps after rehumidification. The principle of tobacco rehumidification and loosening is to pass high-temperature steam into the loosening and rehumidification cylinder. The high-temperature steam can rehumidify the tobacco leaves and blow them apart. However, when the steam is passed to blow the tobacco leaves apart, some smaller tobacco debris will be blown up and accumulated in the air duct, affecting the rehumidification effect. The existing technology is to set a filter on the hot air outlet.

[0003] However, there are some problems with the existing technology, especially in the design of the filter screen at the discharge end. The traditional device uses a pull-out steel wire mesh as the filter screen at the discharge end. This design is prone to blockage and poor ventilation, resulting in instability of the hot air system and affecting the continuity and quality of tobacco leaf processing. Utility Model Content

[0004] The utility model overcomes the drawback of the prior art that the pull-out steel wire mesh is easily blocked and causes poor ventilation, and provides a tobacco loose rehumidification outlet self-cleaning filtering device, in the hope of solving the problem.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A tobacco loose rehumidification outlet self-cleaning filtering device, comprising a tobacco loose rehumidification device, a perforated conveyor belt, a transmission roller, a brush roller, and a waste hopper;

[0007] The tobacco loosening and rehumidification device comprises a shell, a loosening and rehumidification cylinder, and a high-temperature steam pipe. The loosening and rehumidification cylinder is arranged in the shell. The high-temperature steam pipe passes through the shell and enters the loosening and rehumidification cylinder. A hot air outlet is arranged on the shell.

[0008] The perforated conveyor belt is arranged in the housing and installed between the loosening and rehumidifying cylinder and the hot air outlet, and the transmission roller is used to drive the perforated conveyor belt to rotate;

[0009] The brush roller contacts the surface of the conveyor belt with holes, and a waste hopper is arranged below the brush roller, and the waste hopper is communicated with the shell.

[0010] Although the existing pull-out type steel wire mesh can be used as a filter at the discharge end for filtering, tobacco debris will accumulate on the filter, resulting in poor ventilation and instability of the hot air system. The present application designs the filter as a perforated conveyor belt, and designs a brush roller to clean the perforated conveyor belt. The cleaned tobacco debris will fall into the waste hopper, avoiding the accumulation of tobacco debris on the filter and facilitating the later cleaning of the tobacco debris.

[0011] A further technical solution is that the tobacco loosening and rehumidification device includes an observation window;

[0012] The observation window is arranged on the shell.

[0013] The observation window facilitates real-time observation of the operating status of the perforated conveyor belt and the tobacco loosening and rehumidification device.

[0014] A further technical solution is that the perforated conveyor belt is a mesh conveyor belt.

[0015] A further technical solution is that the outlet self-cleaning filter device also includes a transmission device;

[0016] The transmission device is arranged between the transmission roller and the brush roller.

[0017] A further technical solution is that the transmission device is a sprocket or a chain;

[0018] The transmission roller and the brush roller are provided with sprockets, and a chain is provided between the transmission roller and the sprockets of the brush roller.

[0019] A further technical solution is that the outlet self-cleaning filter device also includes a compressed air blowing device;

[0020] The compressed air blowing device comprises a blowing head and an air pipe;

[0021] The blowing head is arranged on the inner side of the conveying belt with holes, and the air pipe is connected with the blowing head.

[0022] Since a brush may not be able to thoroughly clean some tobacco leaf debris with strong adsorption, a compressed air blowing device is added and a blowing head is set on the inside of the perforated conveyor belt. After the work is completed, high-pressure gas can be blown in and the perforated conveyor belt can be further purged by the high-pressure gas to clean the perforated conveyor belt.

[0023] A further technical solution is that a flap door is provided below the waste hopper.

[0024] The function of the flap door below the waste hopper is to remove the tobacco leaf debris that falls into the waste hopper.

[0025] Compared with the prior art, the utility model has at least the following beneficial effects: the utility model designs the filter as a perforated conveyor belt and designs a brush roller to clean the perforated conveyor belt, thereby avoiding the problem of the prior art of using a pull-out screen that needs to be cleaned at any time, and the tobacco leaf debris cleaned from the perforated conveyor belt will fall into the waste hopper, which is convenient for subsequent collection and processing, avoids the accumulation of tobacco leaf debris on the filter, achieves the effect of automatically cleaning the perforated conveyor belt, and improves production efficiency.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] A self-cleaning filter device for the outlet of loose tobacco rehumidification, see Figure 1 , Figure 2 , including, a tobacco loosening and rehumidification device 1, a perforated conveyor belt 2, a transmission roller 3, a brush roller 4, a transmission device 5, a waste hopper 6, and a compressed air blowing device 7;

[0031] The tobacco loosening and rehumidifying device 1 comprises a housing 11, a loosening and rehumidifying cylinder 12, a high-temperature steam pipe, and an observation window 13. The loosening and rehumidifying cylinder 12 is arranged in the housing 11, and the high-temperature steam pipe passes through the housing 11 and enters the loosening and rehumidifying cylinder 12. A hot air outlet 14 is arranged on the housing 11.

[0032] The observation window 13 is disposed on the housing 11 .

[0033] The perforated conveyor belt 2 is arranged in the housing 11 and installed between the loosening and rehumidifying cylinder 12 and the hot air outlet 14. The transmission roller 3 is used to drive the perforated conveyor belt 2 to rotate;

[0034] It should be noted that the perforated conveyor belt 2 can be a general conveyor belt with holes, or it can be a mesh conveyor belt. In the present embodiment, the perforated conveyor belt 2 is a mesh conveyor belt, the aperture of which matches the size of tobacco leaf debris, and can filter the tobacco leaf debris.

[0035] The transmission device 5 is arranged between the transmission roller 3 and the brush roller 4. The transmission device 5 can be a belt transmission, a gear transmission, etc. In this embodiment, the transmission device 5 is a sprocket or a chain;

[0036] The transmission roller 3 and the brush roller 4 are provided with sprockets, and a chain is provided between the sprockets of the transmission roller 3 and the brush roller 4 .

[0037] The brush roller 4 contacts the surface of the perforated conveyor belt 2 , a waste hopper 6 is disposed below the brush roller 4 , the waste hopper 6 is communicated with the housing 11 , and a flap door 61 is disposed below the waste hopper 6 .

[0038] The compressed air blowing device 7 includes a blowing head and an air pipe;

[0039] The blowing head is arranged on the inner side of the perforated conveyor belt 2, and the air pipe is connected to the blowing head.

[0040] When in use, the steam reaches the loosening and rehumidifying cylinder 12 through the high-temperature steam pipe, rehumidifies and blows the tobacco leaves, and the steam is discharged through the hot air outlet 14;

[0041] When the steam is blowing the tobacco leaves apart, tobacco leaf debris is blown up and blown toward the hot air outlet 14 by the steam. The tobacco leaf debris is blocked by the perforated conveyor belt 2 to prevent it from being blown out of the hot air outlet 14 .

[0042] After the tobacco leaf debris is blocked on the perforated conveyor belt 2, the perforated conveyor belt 2 continues to rotate until the perforated conveyor belt 2 contacts the brush roller 4. The brush roller 4 cleans the tobacco leaf debris on the surface of the perforated conveyor belt 2, and the tobacco leaf debris falls into the waste hopper 6 after cleaning.

[0043] During use, even if the brush roller 4 has no independent power, it can still clean the perforated conveyor belt 2 by contact. However, a better technical solution is that the brush roller 4 has a power source, and its rotation speed is different from the rotation speed of the perforated conveyor belt 2. The brush roller 4 has a speed relative to the perforated conveyor belt 2, and the cleaning effect is better.

[0044] In this embodiment, the motor drives the transmission roller 3 to rotate, and sprockets are provided on the transmission roller 3 and the brush roller 4. The transmission roller 3 and the brush roller 4 are driven by chains. By adjusting the tooth ratio between the sprockets, the rotation speed of the brush roller 4 can be made faster or slower than that of the transmission roller 3.

[0045] When the perforated conveyor belt 2 needs to be further cleaned, the compressed air blowing device 7 is used to blow from the inside of the perforated conveyor belt 2, and the brush roller 4 is further used to complete the cleaning of the perforated conveyor belt 2.

[0046] When the whole set of equipment is working, the tobacco leaf debris on the perforated conveyor belt 2 can be observed from the observation window 13, and if there is a problem, the equipment can be stopped in time.

[0047] When the cleaned tobacco leaf debris needs to be cleaned, the flap door 61 below the waste hopper 6 is opened to take out the tobacco leaf debris.

[0048] Although the utility model is described herein with reference to the illustrative embodiments of the utility model, it should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in the present application. More specifically, within the scope disclosed in the present application, multiple variations and improvements can be made to the components and / or layout of the subject combination layout. In addition to the variations and improvements made to the components and / or layout, other uses will also be obvious to those skilled in the art.
