Description

A sisal fiber impurity and water removal machine Technical Field

[0001] This utility model belongs to the field of sisal processing equipment, and specifically relates to a sisal fiber impurity and water removal machine. Background Technology

[0002] After coarse processing, sisal raw materials can be divided into long fibers and short fibers. Before leaving the factory, they need to be cleaned, impurities removed, and dehydrated. Existing sisal fiber impurity removal equipment usually removes impurities and dehydrates sisal fibers by scraping rollers to remove impurities, washing, and then spinning dry. However, this method is not only easy to damage sisal fibers, but also easy to cause material to be mistakenly removed when removing impurities from short fibers, resulting in waste of raw materials. In addition, the complex structure of the equipment increases the production cost of the equipment.

[0003] A fully automatic plant short fiber processing system is disclosed in patent document application number "CN201520094540.0". From the accompanying drawings and specific embodiments of the prior art, it can be seen that when the fiber impurity removal and dehydration device 300 is working, the short fibers 900 enter from the top of the third base 30. The third drive component 33 directly drives the third transmission shaft 31, which in turn drives the spinning wheel 32 to rotate. During the rotation, the short fibers 900 will be wrapped around the hemp rods 36 of the spinning wheel 32. The spinning wheel 32 carries the short fibers 900 and rotates rapidly. Therefore, the water and some residue on the short fibers 900 are separated from the short fibers 900 under the action of centrifugal force and pass through the mesh of the third base 30, thereby dehydrating and purifying the short fibers 900. The short fibers treated by the fiber impurity removal and dehydration device 300 are placed in a drying room or dried by sun exposure or other methods. The spinning wheel in this structure is not only complex, but also easily damages the fiber body when rotating. During the spinning process, small short fibers are also easily removed by mistake, resulting in waste of raw materials. Furthermore, the dehydration is not thorough enough, and drying is still required.

[0004] The above background information is provided only to assist in understanding the utility model concept and technical solution of this utility model, and it does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

[0016] Compared with existing technologies, this utility model has the following beneficial effects:

[0017] 1. The sisal fiber impurity removal and dehydration machine of this utility model conveys sisal fibers to the area below the cover opening of the cover through the conveying section. A high-flow-rate high-pressure blower is installed on the top of the cover, and a water inlet pipe is installed on the side of the cover facing the feed end of the conveying section. The water inlet pipe can pass water to the inner wall of the cover. When the high-pressure blower is turned on, it can not only accelerate the water flow to spray the fibers in the conveying section for impurity removal, but also remove impurities and dehydrate the fibers at the same time through the high-pressure airflow. The equipment has a simple structure and good economy, and will not damage the raw materials, and has better impurity removal and dehydration effects.

[0018] 2. A partition is installed inside the enclosure to form air blowing channels and water spraying channels, thereby separating dry and wet areas. This ensures that the air blowing channels blow out dry air to guarantee the dehydration effect. Furthermore, the lower end of the partition gradually moves towards the inside of the enclosure, causing the inner wall of the water spraying channel to gradually narrow. According to Bernoulli's principle, this increases the speed of the water jet and the air velocity, giving the jetted water greater kinetic energy and improving the impurity removal effect.

[0019] 3. The first and second sides of the cover are respectively provided with first guides, and the distance between the two first guide surfaces gradually increases from top to bottom, thereby increasing the effective length of the cover opening, making the effective distance of water spraying and blowing longer, and improving the impurity removal and dehydration effect; the distance between the second guide surfaces on the third and fourth sides gradually decreases from top to bottom, forming a constriction structure, which can increase the speed of water flow and air flow, and improve the impurity removal and dehydration effect.

[0020] 4. The conveying unit in this utility model can convey sisal fibers through a conveyor belt or a conveyor net. The conveyor belt is used to convey long fibers, and the narrower conveying surface can improve the air-breaking effect of long fibers during the conveying process. The conveyor net is used to convey short fibers, and the wider conveying surface of the conveyor net can provide better support for short fibers.

[0021] 5. The baffle and the first side guard plate in the protective plate assembly can block the sisal fibers and prevent water from getting tangled in the lower part of the conveying section. The second side guard plate, the guide plate, and the first side guard plate can form a water guide channel, which can guide the wastewater after washing to the discharge end and discharge it.

[0036] As shown in Figures 1 and 2, the sisal fiber impurity and water removal machine in this embodiment includes: a conveying section 100, a conveying frame 110, a sprocket 120, a pulley 130, a drive motor 140, a wheel seat 150, a wheel axle 160, a coupling 170, a conveying net 180, a conveyor belt 190, a cover 200, a first side 201, a second side 202, a third side 203, a fourth side 204, a cover opening 210, a partition 220, an air blowing channel 230, a water spraying channel 240, a first guide surface 250, a second guide surface 260, a high-pressure blower 300, a water inlet pipe 400, a manual valve 410, a solenoid valve 420, a support frame 500, a long hole 510, a connecting bolt 520, a locking nut 530, a protective plate assembly 600, a baffle 610, a first side guard plate 620, a second side guard plate 630, a guide plate 640, and a water guide trough 650.

[0037] The cover 200 is mounted above the conveying section 100 via a support frame 500. A high-pressure blower 300 is detachably mounted on top of the cover 200. A cover opening 210 is provided at the bottom of the cover 200, with its orientation perpendicular to the conveying direction of the conveying section 100. A water inlet pipe 400 is installed on the side of the cover 200 facing the feed end of the conveying section 100, and the water inlet pipe 400 is connected to the inner wall of the cover 200. A partition 220 is welded inside the cover 200, dividing the interior of the cover 200 into air blowing channels 2. The high-pressure blower 300 and the water spray channel 240, the air blowing channel 230 and the water spray channel 240 are arranged side by side along the conveying direction of the conveying section 100. One end of the air blowing channel 230 and one end of the water spray channel 240 are both facing the air outlet of the high-pressure blower 300. The other end of the air blowing channel 230 and the other end of the water spray channel 240 extend to the hood opening 210. The lower end of the partition 220 gradually approaches the inner side of the hood 200, so that the distance between the inner walls of the water spray channel 240 gradually narrows. A manual valve 410 and a solenoid valve 420 are connected to the water inlet pipe 400.

[0038] More specifically, the cover 200 includes a first side 201 and a second side 202, which are opposite to each other. The first side 201 corresponds to the feed end of the conveying section 100. The first side 201 and the second side 202 are respectively provided with inclined first guide surfaces 250. The inclination directions of the two first guide surfaces 250 are opposite, and the distance between the two first guide surfaces 250 gradually increases from top to bottom, forming a figure-eight structure, so as to increase the width of the cover opening 210 in the conveying direction of the conveying section 100. The cover 200 includes a third side 203 and a fourth side 204, which are opposite to each other. The orientation of the third side 203 and the fourth side 204 is perpendicular to the conveying direction of the conveying section 100. The third side 203 and the fourth side 204 are respectively provided with inclined second guide surfaces 260. The inclination directions of the two second guide surfaces 260 are opposite, and the distance between the two second guide surfaces 260 gradually decreases from top to bottom, forming an inverted figure-eight structure, so as to increase the airflow velocity at the cover opening 210.

[0039] More specifically, a number of elongated holes 510 are provided on the support frame 500. The length direction of the elongated holes 510 is perpendicular to the conveying direction of the conveying section 100. Matching connecting bolts 520 and locking nuts 530 are provided on the outside of the cover 200. The connecting bolts 520 can pass through the elongated holes 510 and be locked by the locking nuts 530. When the locking nuts 530 are loosened, the connecting bolts 520 can slide along the elongated holes 510, thereby allowing the cover 200 to be adjusted laterally.

[0040] More specifically, the conveyor frame 110 is installed below the cover 200. Wheel seats 150 are installed at both ends of the conveyor frame 110. The lower ends of the wheel seats 150 are connected to the conveyor frame 110 by bolts. An axle 160 is installed at the upper end of the wheel seat 150. Two pulleys 130 are installed side-by-side on each axle 160. Grooves are formed on the pulleys 130. The two ends of the conveyor belt 190 are respectively fitted onto the grooves of one of the pulleys 130. The rotating shaft of the drive motor 140 is coaxially connected to the axle 160 located at the discharge end of the conveying section 100 via a coupling 170. The protective plate assembly 600 includes a baffle 610, a first side guard plate 620, a second side guard plate 630, and a guide plate 640. The baffle 610 is located in the area between the upper and lower transverse belts of the conveyor belt 190. There are two first side guard plates 620, and their tops are welded to the two sides of the baffle 610. The bottom of the first side guard plate 620 extends to the lower side of the conveying section 100 and is fixedly connected to one side of the guide plate 640. The other side of the guide plate 640 is fixedly connected to the second side guard plate 630. The first side guard plate 620, the guide plate 640 and the second side guard plate 630 form a U-shaped water guide channel 650. The guide plate 640 has a downward slope in the conveying direction of the conveying section so that the water can flow to the discharge end of the conveying section 100. It is worth noting that the conveyor belt 190 here can be replaced with steel wire or nylon rope.

[0041] As shown in Figure 3, the conveying unit 100 in this embodiment has another implementation, namely, a sprocket 120 is installed on each of the two axles 160. The sprocket 120 has a double-row tooth structure, and a conveying net 180 is sleeved between the two sprockets 120. The baffle 610 passes through the middle area of ​​the conveying net 180.

[0042] Next, the method of using the sisal fiber impurity and water removal machine in this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0043] In use, the water inlet end of the water inlet pipe 400 is connected to an external water source. If it is necessary to remove impurities from the long fibers, they can be directly conveyed by the conveyor belt 190. During operation, the middle part of the long fiber is hung on the feed end of the conveyor belt 190, and then the high-pressure blower 300 and the manual valve 410 and solenoid valve 420 on the water inlet pipe 400 are opened to allow water to flow into the spray channel 240. The airflow blown out by the high-pressure blower 300 can enter the air blowing channel and the water blowing channel respectively, and accelerate and disperse the water flow in the water blowing channel, so that it is sprayed onto the sisal long fibers to wash and blow away impurities on the long fibers. The conveying unit 100 continues to convey the impurity-removed long fibers to the bottom of the air blowing channel 230 for dehydration and drying. During the conveying process of the long fibers, both ends hang down to the surface of the first side guard plate 620.

[0044] If it is necessary to remove impurities from short fibers, the pulley 130 and conveyor belt 190 can be replaced with sprocket 120 and conveyor net 180. Then, the short fibers can be placed on the conveyor net 180 for high-speed rinsing, impurity removal and drying.

[0045] In summary, the sisal fiber impurity removal and dehydration machine in this embodiment conveys sisal fibers to the area below the opening 210 of the cover 200 via the conveying unit 100. A high-volume high-pressure blower 300 is installed on the top of the cover 200, and a water inlet pipe 400 is installed on the side of the cover 200 facing the feed end of the conveying unit 100. The water inlet pipe 400 can pass water to the inner wall of the cover 200. When the high-pressure blower 300 is turned on, it can not only accelerate the water flow to spray and remove impurities from the fibers in the conveying unit 100, but also remove impurities and dehydrate the fibers simultaneously through high-pressure airflow. The equipment has a simple structure and good economy, and it will not damage the raw materials, thus having a better impurity removal and dehydration effect.
