Description

Technical Field

[0001] This utility model relates to the technical field of refined cotton production, specifically to a refined cotton dust collection device. Background Technology

[0002] The production of refined cotton generates cotton dust, primarily originating from the opening and impurity removal processes of raw cotton linters and the drying process of refined cotton. Currently, the most common method for collecting cotton dust is to use filters to remove it.

[0003] In addition to containing a large number of ultra-short cotton fibers, cotton dust also contains foreign impurities such as wood chips and bamboo chips. These impurities are easily aggregated and clogged by the wind, so the filter needs to be cleaned regularly, otherwise the collection effect of cotton dust will be affected. Utility Model Content

[0004] The purpose of this invention is to provide a refined cotton dust collection device to overcome the aforementioned shortcomings. It requires no filter, avoids clogging, and provides excellent collection results.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A cotton dust collection device for refined cotton includes a hollow tower body, a partition plate, a dust inlet pipe, a dissolved air pipe, an exhaust pipe, a stirring roller, and a motor. The partition plate is fixedly installed inside the tower body, dividing the interior into an upper exhaust zone and a lower dust inlet zone. A mesh is provided at the center of the partition plate. One end of the dust inlet pipe is connected to the lower dust inlet zone of the tower body, and the other end is connected to a first induced draft fan. A dust discharge pipe connected to the tower body is located at the bottom of the tower body, and a counterweight-type airlock flap valve is installed on the dust discharge pipe. An exhaust port is provided at the upper end of the tower body. An exhaust pipe extending upwards from the exhaust port is provided with an exhaust hole. The dissolved air pipe is fixedly installed at the bottom of the water tank by a pair of support columns. An air outlet is provided on the dissolved air pipe. One end of the air outlet is connected to the exhaust port, and the other end of the air outlet is connected to the dissolved air pipe at the bottom of the water tank. The stirring roller is rotatably installed inside the dissolved air pipe. The motor is fixedly installed on the outer wall of the water tank. The output shaft of the motor passes through the outer wall of the water tank and is connected to the stirring roller for transmission.

[0007] Preferably, it also includes guide vanes, with pairs of guide vanes staggered and fixedly installed in the lower dust inlet area of ​​the tower body.

[0008] Preferably, a second induced draft fan is installed on the exhaust pipe.

[0009] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0010] 1. By setting up baffles, the residence time of foreign impurities such as wood chips and bamboo chips in the tower can be extended, the air velocity can be reduced, and the sedimentation and collection of foreign impurities can be facilitated.

[0011] 2. By setting up a partition with mesh and an exhaust pipe with exhaust holes, the larger materials in the cotton dust in the air can be intercepted and collected by the fine holes opened on the partition and the exhaust pipe respectively, leaving only the fine cotton dust that can be carried by the wind, which helps to reduce the difficulty of subsequent cotton dust collection.

[0012] 3. By setting up a dissolved air tube, fine cotton dust is sent into the dissolved air tube in the water tank, and under the action of the stirring roller, the fine cotton dust comes into full contact with the water, and is washed and separated by water, resulting in good collection effect.
