Description

Technical Field

[0001] The utility model relates to the technical field of refined cotton processing, in particular to a cotton dust recovery device for opening refined cotton. Background Art

[0002] In the production process of refined cotton, the first step is cotton picking and processing. Cotton generally matures in autumn and is picked at the right time. The picked cotton will be sorted manually or mechanically to remove impurities and immature cotton fibers. After picking and preliminary processing, the cotton will further undergo the steps of impurity removal and fiberization. The cotton will be placed in a cotton bin for soaking and steaming to remove impurities and grease in the cotton. The cotton will then be transferred to an opener, where it will be broken down into fibers through mechanical squeezing and tearing. The fiber will then be further cleaned and dried. The fiber will be sent to a cleaning machine, where water flow and friction will be used to remove dirt and impurities on the fiber surface. The cleaned fibers are sent to the dryer, where they are quickly dried by hot air or the sun to ensure that the subsequent processes proceed smoothly. The dried fibers will be further combed and stretched. The fibers are sent to the combing machine, where they are arranged in parallel by mechanical combing, and short fibers and impurities in the fibers are removed. The fibers are then sent to the stretching machine, where they are stretched mechanically to make the length and fineness of the fibers more uniform. The stretched fibers are further leveled and refined, where they are sent to the leveling machine, where mechanical vibration and pressure are used to make the fibers more level, and burrs and agglomerations on the fiber surface are removed. The leveled fibers are then sent to the refinement machine. In the machine, the fineness of the fiber is further improved through mechanical shearing and friction to increase the softness and glossiness of the fiber. The refined fiber will be further processed and packaged, and the fiber will be sent to the spinning machine, where it will be converted into cotton yarn through mechanical rotation and stretching. The cotton yarn will then be sent to the textile machine for weaving to make various fabrics. Finally, the finished product will be inspected, trimmed and packaged to ensure the quality and appearance of the product. Through the above production process, the production process of refined cotton is completed. Cotton dust is inevitably generated in the production process of refined cotton. Cotton dust is a plant-derived organic dust, which is mainly generated in the production process of cotton. It is generated by the growth, picking, subsequent processing and storage of cotton. A mixture of various substances gradually accumulated during the production process, including crushed plant components, fibers, bacteria, fungi, dust, pesticides, non-cotton plant components and other pollutants. Cotton dust can cause cotton dust disease. During the quilt production process, if workers do not pay attention to protection, they are easily harmed by cotton dust. Therefore, appropriate preventive measures must be taken, such as reducing the dust concentration in the working environment and strengthening personal protection. These are the keys to preventing cotton dust disease. Traditional cotton dust prevention equipment generally uses filters for filtration, but during the filtration process, as cotton dust accumulates, the ventilation volume of the filter will gradually decrease. It is necessary to stop working and disassemble and clean the filter every once in a while, which is not conducive to improving the overall filtration and collection efficiency.

[0030] The contact self-cleaning mechanism comprises: a closing plate 6, which is slidably mounted on the side surface of the outer box body 1, and an electric push rod 7 is fixedly mounted on the outer surface of the outer box body 1, a cleaning wheel 8 is arranged inside the outer box body 1, and a rotating connecting rod 9 is installed on the outer surface of the middle section of the cleaning wheel 8, a rotating displacement rod 10 is installed inside the upper end of the outer box body 1, and a motor 11 is fixedly mounted on the outer surface of the upper end of the outer box body 1, a gear rod 12 is fixedly mounted on the inner surface of the upper end of the outer box body 1, and connecting gears 20 are fixedly mounted on the side surfaces of both ends of the cleaning wheel 8;

[0031] One end of the closing plate 6 penetrates the inner surface of the outer box body 1 and is fixedly connected to the filter plate 4, the outer surface of the closing plate 6 fits the outer surface of the outer box body 1, and the lower end of the electric push rod 7 is fixedly connected to one end of the closing plate 6;

[0032] The side surface of the cleaning wheel 8 is provided with hard bristles, the connecting rod 9 is slidably connected to the outer box body 1, and the connecting rod 9 is threadedly connected to the displacement rod 10, and one end of the displacement rod 10 is fixedly connected to the output shaft of the motor 11, and the gear rod 12 is meshed and connected to the cleaning wheel 8 through the connecting gear 20, and the gear rod 12 is located above the connecting gear 20;

[0033] During the normal filtering process, the air in the workshop drawn by the air pump is injected into the interior of the outer box body 1 through the air inlet joint 3 and the guide pipe 2. At this time, the air passes through the filter plate 4 and is discharged downward through the air outlet pipe 5. When too much cotton dust accumulates on the surface of the filter plate 4, the electric push rod 7 starts to drive the filter plate 4 to slide upward through the closing plate 6 until the upper surface of the filter plate 4 is in contact with the bristles on the outer surface of the cleaning wheel 8. At this time, the motor 11 starts to drive the connecting rod 9 to slide inside the outer box body 1 through the threaded connection between the displacement rod 10 and the connecting rod 9.

Example

[0034] This embodiment is based on the embodiment 1 and discloses that: a pressure cleaning mechanism is provided on the surface of the outer box body 1, and the pressure when the filter plate 4 moves downward prevents the filter plate 4 from being blocked by cotton dust;

[0035] The pressure cleaning mechanism includes: a bottom plate 13, the bottom plate 13 is fixedly arranged inside the lower end of the outer box body 1, and a leakage hole 14 is opened on the outer surface of the bottom plate 13, the side surface of the outer box body 1 below the bottom plate 13 is penetrated by a switching plate 15, and a switching hole 16 is opened on the outer surface of the switching plate 15, a push plate 17 is fixedly arranged on the upper surface of one end of the switching plate 15 located outside the outer box body 1, and a contact column 18 is fixedly arranged on the upper end side surface of the push plate 17, and an extrusion rod 19 is fixedly arranged on the outer surface of one side of the connecting rod 9;
