Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tobacco processing, and particularly relates to a tobacco stem water removal device. BACKGROUND

[0002] In tobacco processing, the cleaning of tobacco stems is mainly completed by a stem washing machine. The main task of the stem washing machine is to remove dust, sand, metal and non-metal impurities on the surface of the tobacco stems through circulating water, to remove pectin in the tobacco stems, and to increase the moisture content of the tobacco stems, so that the tobacco stems are clean and soft, and meet the processing requirements of subsequent processes. At the same time, the stem washing machine also plays a good protective role on the blades of the subsequent cutting machine. After the water washing treatment, the tobacco stems still need to be dehydrated before subsequent processing. If the moisture content of the tobacco stems is too high, the quality of the tobacco stems will be reduced, and even the tobacco stems will be blackened and cannot be processed. Therefore, the dehydration link after the tobacco stem water washing is very important. At present, the method of air blowing is usually used for the dehydration treatment of the water-washed tobacco stems. The water-washed tobacco stems are placed on a conveying belt, and an air blower is used to blow the tobacco stems to remove the water on the surface of the tobacco stems. However, this dehydration method has the following problems: the air blower can only remove the water on the surface of the tobacco stems, and cannot handle the water contained in the tobacco stems with high moisture content, so the dehydration effect is poor. Secondly, for large-volume tobacco stems, the tobacco stems are stacked on the conveying belt to form a tobacco stem pile. The air blower can only blow the outer surface of the tobacco stem pile, and the water in the inner part of the tobacco stem pile needs to be manually removed by blowing. The dehydration efficiency is low, and the water hidden in the inner part of the tobacco stem pile may not be effectively treated due to uneven blowing. CONTENT OF THE UTILITY MODEL

[0037] Specifically, the rotation direction of the barrel body 11 in the present application refers to the rotation of the barrel body 11 around its axis, Figure 2 The arrow X points to the rotation direction of the barrel body 11.

[0040] As a preferred embodiment of the present embodiment, as shown in Figure 3As shown, the barrel body 11 has a feeding port 12 and a discharging port 13 at both ends of the extension direction of the barrel body 11, the plurality of poking plates 3 form at least one poking group, and the plurality of poking plates 3 in the poking group are sequentially and spacedly arranged along the rotation direction of the barrel body 11 and the extension direction from the feeding port 12 to the discharging port 13.

[0041] By arranging the feeding port 12 and the discharging port 13 at both ends of the extension direction of the barrel body 11, a space is provided for placing the tobacco stems before dehydration and taking out the tobacco stems after dehydration. By arranging the plurality of poking plates 3, the driving efficiency of the tobacco stem separating barrel 1 on the tobacco stems is enhanced. The plurality of poking plates 3 collectively poke the tobacco stems to drive the tobacco stems to rotate, which further improves the rotation rate of the tobacco stems and provides a guarantee for the centrifugal force of the tobacco stems.

The diameter D of the water passing opening 111 satisfies 1mm≤D≤2.5mm, which provides a channel for the water separated from the tobacco stems in the separating chamber 2 to be discharged outward, so that the water droplets in the separating chamber 2 have sufficient space to be discharged outward. On this basis, the size of the water passing opening 111 is not too large, which prevents the tobacco stems from being thrown out of the separating chamber 2 through the water passing opening 111. In the present embodiment, the diameter D of the water passing opening 111 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.5mm, 2mm, 2.4mm, 2.41mm, 2.5mm, or any value between 1mm and 2.5mm.

[0044] As a preferred embodiment of the present application, the barrel body 11 has a feeding port 12 and a discharging port 13 at both ends of the extension direction of the barrel body 11.

The tobacco stem dewatering device further comprises a conveying mechanism located below the discharging port 13. The conveying mechanism comprises a conveying belt 4, and the projection of the discharging port 13 in the vertical direction falls on the conveying belt 4.

[0045] The barrel 11 is obliquely extended, the feeding port 12 is arranged above the barrel 11, and the discharging port 13 is arranged below the barrel 11. When tobacco stems are fed, the tobacco stems can only be poured into the feeding port 12, and then slide into the separation cavity 2 under the action of gravity. After dehydration is completed, the tobacco stems can slide onto the conveying belt 4 under the action of gravity, and then are conveyed to a next process or are stored, thereby improving processing efficiency.

[0046] Preferably, the barrel 11 further comprises a sealing plate arranged at the discharging port 13. The sealing plate is movably connected with the barrel 11 and has a closed position for closing the discharging port 13 and an open position for opening the discharging port 13.

[0048] The connecting rod 142 has a first end connected with the transmission shaft 141 and a second end connected with the barrel wall of the barrel 11. The rotation of the transmission shaft 141 drives the connecting rod 142 to rotate around the first end, and the barrel 11 rotates under the drive of the second end. That is, the transmission shaft 141 serves as the power source for the rotation of the barrel 11. The transmission shaft 141 occupies a small space during operation. The barrel 11 synchronously rotates with the transmission shaft 141. The real-time performance of the rotation of the barrel 11 is strong. The rotation speed of the barrel 11 can be controlled by the rotation speed of the transmission shaft 141 to adjust the centrifugal force of the tobacco stems in the separation cavity 2, so as to adjust the dehydration rate of the tobacco stems.

[0049] As a preferred example in the present embodiment, the number of the connecting rods 142 is multiple. The multiple connecting rods 142 are arranged in a circumferential direction of the transmission shaft 141 and are spaced apart from each other. A material passing gap is arranged between adjacent two connecting rods 142. The number of the connecting rods 142 is set to multiple, which improves the connection strength between the transmission shaft 141 and the barrel wall, reduces the force transmission pressure of a single connecting rod 142, and the connecting rods 142 are spaced apart from each other, which provides a feeding space for an operator to feed the separation cavity 2.

By arranging the water collecting barrel 5, the water separated from the tobacco in the separation cavity 2 can be collected, so as to realize the secondary use of the separated water. The arrangement of the drainage plate can guide the water in the separation cavity 2 moving outwards through the water passing opening 111, so as to reduce the probability of the water splashing everywhere, and help the water collecting barrel 5 to collect the water.

[0051] As a preferred embodiment of the present application, the bottom of the water collecting barrel 5 is provided with a water guiding groove. By arranging the water guiding groove at the bottom of the water collecting barrel 5, the water in the water collecting barrel 5 can be discharged through the water guiding groove.
