Description

Technical Field

[0001] The present invention relates to the technical field of cotton processing, and more precisely, to a vibrating, drying and impurity-removing machine for seed cotton rollers. Background Art

[0002] At present, China is a major country in cotton production and consumption, and cotton processing and textile play an important role in the national economy. Due to national conditions, there are problems such as high content of foreign fibers and impurities in locally produced cotton and machine-picked cotton. This problem has not been effectively solved for a long time, seriously affecting the quality of cotton yarn and fabric, and becoming a major problem recognized in China's textile industry. Therefore, in the vast cotton processing industry in China, the pre-treatment process of ginning must effectively clean impurities. It can be seen that the impurity cleaning technology in the seed cotton stage is of great significance to the healthy development of China's cotton industry chain.

[0003] Existing seed cotton cleaning technologies mainly achieve impurity cleaning through the hooks of the spiked shaft, the gaps of the spacer grid, the separation of saw teeth, and the beating of individual rollers.

[0004] The Chinese utility model patent with the publication number CN208312973U discloses a seed cotton mixing box, a drying tower device, and a heating fan. The seed cotton mixing box is connected to the material inlet of the drying tower device through a seed cotton conveying pipeline, and the heating fan is connected to the air flow channel inlet of the drying tower device through an air flow pipeline. The drying tower device is also provided with a plurality of upper and lower staggered partitions, and cavities are arranged in the partitions; ventilation holes are also opened on the partitions, and heating units are arranged in the cavities. However, the technical problem it has is that during the drying process of seed cotton, a large amount of impurities are inevitably generated. If the impurities cannot be effectively cleaned, it will cause hazards such as channel blockage and also increase the burden on the equipment.

[0005] The Chinese invention patent of CN102560692A discloses a seed cotton cleaning machine with impurity removal and electric drying functions, including a frame with a seed cotton inlet and an outlet, and a drying and cleaning device inside the frame; the drying and cleaning device consists of a hot air device and multiple groups of electrically heated spiked rollers. A waste discharge grille is arranged around each group of electrically heated spiked rollers, and the waste discharge grilles are connected to each other by baffles; a cleaning device for removing bell shells or stunted petals is also arranged below the drying and cleaning device inside the frame; both the drying and cleaning device and the cleaning device are connected to a driving motor that provides power for the drying and cleaning device and the cleaning device. The technical problems it has are: heating is carried out through the electrically heated spiked rollers, the contact time of cotton with the electrically heated spiked rollers is short, the cotton is not continuously heated when passing through the electrically heated spiked rollers, and for the electrically heated spiked rollers, it is difficult to set the electric heating components and the application is relatively difficult; moreover, the hot air device blows hot air from the upper side of the electrically heated spiked rollers towards the direction of the electrically heated spiked rollers. Due to the effect of hot air rising and cold air falling, it is difficult for hot air to act evenly on the surface of the processed and conveyed cotton. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a vibrating, drying and impurity-removing machine for unginned cotton. This device conveys and removes impurities through the operation of a vibrating impurity-removing device with layered rollers. During the conveying process, hot air is input through a drying device for drying. The impurity removal and heating are uniform, and the effect is better.

[0007] To solve the above technical problems, the present invention adopts the following technical means:

[0008] A vibrating, drying and impurity-removing machine for unginned cotton includes a vibrating impurity-removing device with rollers and a drying device. The vibrating impurity-removing device with rollers is provided with a cotton inlet, a cotton outlet and a hot air inlet. The vibrating impurity-removing device with rollers further includes a channel steel frame, a roller shaft cage, a scraper shaft, a double-layer impurity-removing auger and an auger partition grille, and a driving motor. The roller shaft cage is formed by arranging multiple roller shafts side by side. The roller shafts are driven by a motor through belt pulleys. There is a rotation interval between adjacent roller shafts, and the rotation interval is larger than the particle size of cotton seeds. The roller shafts are positioned and installed on the side wall panels on both sides; heat preservation boxes are provided on both sides of the roller shaft cage; the heat preservation boxes are of cavity structure, and the heat preservation boxes are provided with hot air holes, and the hot air holes are communicated with the hot air inlet; there are shaft holes below the hot air holes, and side wall panels are provided on the outer sides of the heat preservation boxes. The shaft ends of the roller shafts are positioned and installed on the side wall panels on both sides after passing through the shaft holes; the axis of the hot air holes blows downward to the side at a certain acute angle with the direction of cotton flow, which has a wind pressure effect on the conveyed cotton and is more conducive to impurity removal; springs and sealing gaskets are arranged between the heat preservation boxes and the side wall panels along the axial direction of the roller shafts, which can effectively prevent hot air from leaking out along the gap between the roller shafts and the heat preservation boxes; the roller shaft cages are arranged in multiple layers, and the cotton outlet end of the upper layer is arranged above the cotton inlet end of the lower layer; each layer of roller shaft cage is driven by an independent driving motor; the two scraper shafts are arranged directly below the roller shaft cage, and the two scraper shafts are arranged parallel to the roller shafts; the two scraper shafts are connected by a chain wheel and a drag chain, and the drag chain is equipped with corresponding cleaning brushes. The cleaning brushes are strip-shaped and are arranged parallel to the scraper shafts. During the process of the roller shafts rotating and conveying, impurities fall onto the drag chain under the continuous sieving, hot air blowing and gravity, and are conveyed to the double-layer impurity-removing auger; the double-layer impurity-removing auger is arranged below the scraper shaft at the discharge end. The double-layer impurity-removing auger is divided into an upper-layer impurity-removing auger and a lower-layer impurity-removing auger. There is an auger partition grille between the upper-layer impurity-removing auger and the lower-layer impurity-removing auger, and the gap between adjacent partitions of the auger partition grille is smaller than the size of a single unginned cotton; the drying device inputs hot air into the vibrating impurity-removing device with rollers through the hot air inlet.

[0009] The advantages of the present invention are as follows:

[0010] First: The conveying capacity is increased and it is not easy to be blocked. During the conveying process of wet cotton, if the cotton feeding is uneven, if accumulation occurs at the rotating roller, it is easy to cause blockage. This device adopts a supporting roller shaft cage, so that the wet cotton falls onto the horizontally arranged supporting roller shaft cage and is then conveyed away, and it is not easy to accumulate, effectively reducing the blockage of wet cotton.

[0011] Second: The cotton is evenly spread out, and the hot air has good fluidity, and the heating and dehumidification effect is good. The supporting roller shafts arranged at intervals on the roller shaft cage convey the cotton, enabling the cotton to be evenly spread on the supporting roller shafts. When the hot air flows along the heating and conveying channel, the air flow can evenly contact the cotton being conveyed, facilitating the heating and dehumidification of the cotton. The supporting roller shafts arranged at intervals have air permeability, further improving the heating and dehumidification effect. In addition, the hot air blown out from the hot air holes has a different wind direction from the hot air in the heating and conveying channel, and it is easy to form a turbulent flow to improve the heating and dehumidification effect.

[0012] Third: It is conducive to the timely separation of impurities and separated cotton seeds. The vibration, stabbing, pulling, and beating effects of the supporting roller shaft cage, combined with hot air drying, make it easy to break the boll shells and small leaves in the unginned cotton, and the cotton seeds and impurities that fall off under the action of force pass through the supporting roller shafts downward onto the drag chain under the action of the wind pressure, and are conveyed by the drag chain to the double-layer impurity removal auger. Since the gap between adjacent partitions of the auger partition grille is smaller than the size of a single unginned cotton seed, the cotton seeds are discharged and collected for utilization by the upper-layer impurity removal auger, and other small-sized impurities are collected and processed by the lower-layer impurity removal auger; the impurities separated by the supporting roller shaft cage on each layer are timely conveyed and processed by the drag chain and double-layer impurity removal auger on that layer, enabling the timely separation of impurities and separated cotton seeds. After each layer of cotton is processed, the cotton will be cleaner and looser due to the timely cleaning of impurities and separated cotton seeds.

[0013] Fourth: The modular setting of the unginned cotton supporting roller vibration impurity removal device in layers facilitates maintenance and disassembly.

[0014] The further preferred technical solutions are as follows:

[0015] The driving motor also drives the double-layer impurity removal auger and the scraper shaft through chain drive.

[0016] When the driving motor drives the driving motor, it also drives the double-layer impurity removal auger and the scraper shaft on this layer.

[0017] The supporting roller shaft cages are arranged in four layers, namely the first supporting roller shaft cage, the second supporting roller shaft cage, the third supporting roller shaft cage, and the fourth supporting roller shaft cage. The structures of each layer are the same. The first supporting roller shaft cage and the third supporting roller shaft cage have the same forward direction, the second supporting roller shaft cage and the fourth supporting roller shaft cage have the same forward direction, and the first supporting roller shaft cage and the second supporting roller shaft cage have opposite forward directions.

[0018] The above settings enable the cotton being conveyed to be conveyed layer by layer in an S shape in the machine body, and impurity removal and heating are carried out layer by layer.

[0019] A heat preservation layer is provided directly above and at both ends of each layer of the idler shaft cage; the heat preservation box and the heat preservation layer of each layer of the idler shaft cage enclose a heating and conveying channel.

[0020] By providing the heat preservation layer, a heating and conveying channel is formed between each layer of the idler shaft cage and the heat preservation layer, promoting the gas flow in the heating and conveying channel, and better heat preservation and heating.

[0021] The overall shape of the idler shaft cage is box-shaped, and the layers are connected by bolt joints and bolts on the channel steel frame. It is convenient for installation and disassembly and easy to maintain.

[0022] The idler shaft is of a hollow structure. On the circumferential surface of the idler shaft, partition strips are provided at intervals along the axial direction, and the plurality of partition strips are evenly arranged on the central roller shaft; along the axis of the central roller of the idler shaft, a plurality of partition plates are arranged at intervals, and the plurality of partition plates are evenly arranged on the central roller shaft; the plurality of partition strips are evenly arranged on the periphery of the partition plates.

[0023] Through the partition strips and partition plates arranged at intervals, the partition plates support the partition strips, and the partition strips increase the force on the wet cotton, making it not easy to slip and accumulate during transportation; and the partition strips also increase the vibration, stabbing, pulling and slapping effects on the conveyed wet cotton during work, so that the impurities in the cotton are separated and fall off.

[0024] The air outlet of the pipeline of the drying device is connected to the hot air inlet of the idler vibration and impurity removal device, and the air inlet height is higher than the idler shaft cage. The hot air flows along the surface of the idler shaft cage, making full contact with the conveyed cotton on a plane, and part of the hot air also rises or descends and flows through the intervals between the idler shafts of the idler shaft cage, heating the cotton, so as to heat the conveyed cotton more evenly and fully in the horizontal and vertical directions, and improve the drying efficiency.

[0025] The drying device includes a high-speed fan, an air inlet pipeline, a heating box body, finned tubes, and mica electromagnetic heating wires; finned tubes are horizontally and equally spaced and installed in parallel in the heating box body, and mica electromagnetic heating wires pass through the middle of the finned tubes; one end of the air inlet pipeline is connected to the air inlet of the heating box body, and the other end is connected to two high-speed fans. The two ends of the mica electromagnetic heating wires are connected to the electromagnetic induction heating power supply. The air blown out by the high-speed fans is heated when passing through the finned tubes, and the hot air enters the idler vibration and impurity removal device for heating and drying.

[0026] The finned tubes are formed by winding spiral blades; the mica electromagnetic heating wires are wound in an S shape among a plurality of finned tubes. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] The present invention will be further described below in conjunction with embodiments.

[0041] See Figure 1 It can be seen that a vibrating and drying and impurity-removing machine for seed cotton rollers of the present invention is composed of a roller vibrating impurity-removing device 1 and a drying device 2.

[0042] See Figures 1 - 3 It can be seen that the roller vibrating impurity-removing device 1 is composed of a channel steel frame 108, a roller shaft cage 101, a scraper shaft 103, a double-layer impurity-removing auger 102 and an auger partition grid 1023, and a driving motor 106.

[0043] See Figures 1 - 10 It can be seen that the roller shaft cage 101 is formed by arranging a plurality of roller shafts 1011 in parallel. The roller shafts 1011 are driven by the motor 106 through belt pulleys. There is a rotation interval between adjacent roller shafts 1011, and the rotation interval is larger than the particle size of cotton seeds. The roller shafts 1011 are positioned and installed on the side wall plates 1013 on both sides; heat preservation boxes are arranged on both sides of the roller shaft cage 101; the heat preservation boxes are arranged on the channel steel frame 108, and shaft holes are provided on the heat preservation boxes; the side wall plates 1013 are arranged outside the heat preservation boxes, and the roller shafts 1011 are connected to the side wall plates 1013 through bearing seats. Springs 1015 and sealing washers 1014 are arranged between the heat preservation boxes and the side wall plates 1013 along the axial direction of the roller shafts 1011, effectively ensuring the sealing and heat preservation effects. The heat preservation box is of a cavity structure, and the heat preservation box is provided with hot air holes 10121. The hot air holes 10121 are communicated with the hot air outlets through connecting pipes. The hot air from the hot air outlets enters the hot air holes 10121 through the connecting pipes and then blows onto the cotton conveyed by the roller shaft cage 101; the axes of the hot air holes 10121 blow obliquely downward to the side at a certain acute angle with the direction of the cotton flowing movement, having a wind pressure effect on the conveyed cotton and being more conducive to impurity removal.

[0044] See Figure 3 It can be seen that the roller shaft cage 101 is arranged in a box shape. The roller shafts 1011 at the feeding end of the roller shaft cage 101 are laid to the end of the roller shaft cage 101, and there is a cotton discharging interval between the roller shafts 1011 at the discharging end of the roller shaft cage 101 and the end plate of the roller shaft cage 101.

[0045] The roller shaft cage 101 is arranged in four layers, namely the first roller shaft cage, the second roller shaft cage, the third roller shaft cage, and the fourth roller shaft cage. The structure of each layer is the same, and the cotton output end of the upper layer is arranged above the cotton input end of the lower layer; each layer of the roller shaft cage 101 is driven by an independent driving motor 106; the driving motor 106 also drives the double-layer impurity removal auger 102 and the scraper shaft 103 through chain drive. The advancing directions of the first roller shaft cage and the third roller shaft cage are the same, the advancing directions of the second roller shaft cage and the fourth roller shaft cage are the same, and the advancing directions of the first roller shaft cage and the second roller shaft cage are opposite; heat insulation layers 107 are provided above each layer of the roller shaft cage 101 and at both ends of the unginned cotton roller vibration impurity removal device 1; the heat insulation box and the heat insulation layer 107 of each layer of the roller shaft cage 101 enclose a heating and conveying channel.

[0046] The roller shaft cage 101 is integrally arranged in a box shape, and the layers are connected by bolt joints and bolts on the channel steel frame 108, which is convenient for installation and disassembly and easy for maintenance.

[0047] The roller shaft 1011 is of a hollow structure, and partition strips 10111 are arranged at intervals along the axial direction on the circumferential surface of the roller shaft 1011. The plurality of partition strips 10111 are evenly arranged on the central roller shaft, and the gap between every two adjacent partition strips 10111 among the plurality of partition strips 10111 is smaller than the size of a single unginned cotton.

[0048] For the roller shaft 1011, a plurality of spacer plates 10112 are arranged at intervals along its central roller axis, and the plurality of spacer plates 10112 are evenly arranged on the central roller shaft; the plurality of partition strips 10111 are evenly arranged on the peripheries of the spacer plates 10112.

[0049] The two scraper shafts 103 are arranged directly below the roller shaft cage 101, and the two scraper shafts 103 are arranged parallel to the roller shaft 1011. The two scraper shafts 103 are connected by a sprocket and a drag chain, and a corresponding cleaning brush 1031 is equipped on the drag chain. The cleaning brush 1031 is strip-shaped and is arranged parallel to the scraper shaft 103. During the rotation and conveying process of the roller shaft 1011, impurities fall onto the drag chain under the continuous sieving, hot air blowing, and gravity, and are conveyed to the double-layer impurity removal auger 102 through the end of the roller.

[0050] The cleaning brushes 1031 are evenly distributed on the drag chain.

[0051] The double-layer impurity removal auger 102 is arranged below the scraper shaft 103 at the discharge end.

[0052] The double-layer impurity-removing auger 102 mentioned above is divided into an upper-layer impurity-removing auger and a lower-layer impurity-removing auger 1022. There is an auger partition grille 1023 between the upper-layer impurity-removing auger and the lower-layer impurity-removing auger 1022. The gap between adjacent partitions of the auger partition grille 1023 is smaller than the size of a single-seed cotton; and the helix directions of the auger blades of the upper-layer impurity-removing auger 1021 and the lower-layer impurity-removing auger 1022 are opposite; the diameter of the partition 10111 is 8 mm.

[0053] See Figure 1 , Figures 10 - 12 As can be seen, the drying device 2 described above is composed of a high-speed fan 201, an air inlet pipe 202, a heating box body 203, finned tubes 204, and mica electromagnetic heating wires 205; the finned tubes 204 are horizontally and equally spaced and installed in parallel inside the heating box body 203, and the mica electromagnetic heating wires 205 pass through the middle of the finned tubes 204.

[0054] The air outlet of the pipeline of the drying device 2 is connected to the hot air inlet of the roller vibration impurity-removing device 1 and the height of the air inlet is higher than that of the roller shaft cage 101. The hot air flows along the air outlet pipe 206 and enters the surface of the roller shaft cage 101 through the hot air holes 10121, making full contact with the cotton being conveyed on a plane. And part of the hot air also rises or descends and flows through the gaps between the roller shafts 1011 of the roller shaft cage 101 to heat the cotton, so as to heat the conveyed cotton more evenly and sufficiently in the horizontal and vertical directions and improve the drying efficiency.

[0055] An insulating box body is assembled outside the heating box body 203, and insulating cotton is filled between the insulating box body and the heating box body 203.

[0056] One end of the air inlet pipe 202 is connected to the air inlet of the heating box body 203, and the other end is connected to two high-speed fans 201. Both ends of the mica electromagnetic heating wire 205 are connected to an electromagnetic induction heating power supply. The air blown out by the high-speed fans 201 is heated when passing through the finned tubes 204, and the hot air enters the roller vibration impurity-removing device 1 for heating and drying.

[0057] The finned tubes 204 are formed by winding spiral blades; the mica electromagnetic heating wires 205 are wound in an S shape among a plurality of finned tubes 204.

[0058] The working principle of the present invention is as follows:

[0059] The upper-level cotton-seed loosening mechanism feeds materials to the cotton-seed roller vibration and drying impurity-removing machine. First, it evenly drops to one end of the topmost roller shaft cage 101. The roller shafts 1011 in the roller shaft cage 101 are driven by sprockets and chains, and are slapped by the partitions 10111 on the roller shafts 1011 with the same rotation direction.

[0060] The air outlet of the outlet pipe of the drying device 2 is connected to the hot air hole 10121 of the heat preservation box through a pipe.

[0061] The generated impurities pass through the gaps of the partition strips 10111 on the roller shaft 1011 and fall under the action of gravity to the lower scraper shaft 103. The scraper shaft 103 is equipped with corresponding impurity cleaning brushes 1031. The impurities fall onto the impurity cleaning brushes 1031 on the scraper shaft 103 under the sieving of the roller shaft cage 101, the blowing of the hot air, and the action of gravity, and are transported by the impurity cleaning brushes 1031 to the inlet of the double-layer impurity discharging auger 102.

[0062] In the double-layer impurity discharging auger 102, the spiral blades of the upper-layer impurity discharging auger 1021 and the lower-layer impurity discharging auger 1022 rotate in opposite directions, and the outlets of the upper and lower-layer impurity discharging augers 1022 are also opposite; the impurities with some small amounts of unginned cotton transported by the scraper shaft 103 first obtain the available unginned cotton through the upper-layer impurity discharging auger 1021. At this time, the impurities without unginned cotton fall through the grid bar gaps under the upper-layer impurity discharging auger 1021 to the lower-layer impurity discharging auger 1022, and the impurities are then smoothly discharged by the lower auger.

[0063] The roller shaft 1011, the double-layer impurity discharging auger 102, and the double-layer impurity discharging auger 102 and the scraper shaft 103 are all driven by chains and driven by the drive motor 106, which is convenient for adjusting the rotation speed.

[0064] The beneficial effects of this embodiment are as follows:

[0065] First: The conveying capacity is increased and it is not easy to be blocked; during the conveying process of wet cotton, if the cotton feeding is uneven, if accumulation occurs at the roller, it is easy to cause blockage. This device adopts a roller shaft cage, so that the wet cotton falls onto the horizontally arranged roller shaft cage and is immediately conveyed away, and it is not easy to accumulate, effectively reducing the blockage of wet cotton.

[0066] Second: The cotton is evenly laid, and the hot air has good fluidity and good heating and dehumidification effects: The roller shafts arranged at intervals on the roller shaft cage convey the cotton, so that the cotton is evenly laid on the roller shafts. When the hot air flows along the heating and conveying channel, the air flow can evenly contact the cotton being conveyed, which is convenient for heating the cotton for dehumidification. The roller shafts arranged at intervals have air permeability, further improving the heating and dehumidification effects; in addition, the hot air blown out from the hot air holes has a different wind direction from the hot air in the heating and conveying channel, and it is easy to form a turbulent flow to improve the heating and dehumidification effects.

[0067] Third: It is conducive to the timely separation of impurities and cotton seeds detached from the cotton. The vibration, tearing, pulling, and beating of the roller shaft cage are combined with hot air drying, making it easy to break the boll shells and small leaves in the unginned cotton. The cotton seeds and impurities that fall off under the action of force pass through the roller shaft downward under the action of air pressure and fall onto the drag chain, which transports them to the double-layer impurity removal auger. Since the gap between adjacent bars of the auger partition is smaller than the size of a single unginned cotton, the cotton seeds are discharged and collected for utilization by the upper-layer impurity removal auger, while other small impurities are collected and processed by the lower-layer impurity removal auger. The impurities separated by the roller shaft cage on each layer are promptly transported and processed by the drag chain and double-layer impurity removal auger on that layer, enabling the timely separation of impurities and cotton seeds detached from the cotton. After each layer of cotton is processed, the cotton will be cleaner and looser due to the timely cleaning of impurities and cotton seeds detached from the cotton.

[0068] Fourth: The layered modular setting of the unginned cotton roller vibration impurity removal device facilitates maintenance and disassembly.

[0069] The above are only the preferred and feasible embodiments of the present invention, and do not limit the scope of rights of the present invention. Any equivalent structural changes made by using the content of the specification and drawings of the present invention are included within the scope of rights of the present invention.
