Description

Technical Field

[0001] The invention relates to the technical field of dust filtering equipment, in particular to a dust filtering device for cellulose production. Background Art

[0002] The raw materials for producing cellulose are usually wood pulp, cotton, hemp, etc. When the raw materials are crushed and pulverized, mechanical force reduces the size of the material and generates a large amount of dust. This step is the main link in the generation of dust. When the fiber dust in the cellulose being produced is mixed with the crushed plant fiber, the quality of the cellulose product produced will be reduced. Therefore, it is necessary to filter and separate the plant fiber and the fiber dust generated by the crushing, and collect the plant fiber and fiber dust separately to improve the production quality of cellulose.

[0003] When filtering plant fibers and fiber dust, they are usually placed in a solution to achieve filtration separation. However, when the plant fibers and fiber dust are filtered out of the solution, a lot of solution will remain on the surface of the plant fibers and fiber dust, which is not conducive to the subsequent production and use of cellulose. In addition, the plant fibers after filtration and separation are prone to generate static electricity during transportation, thereby absorbing dust. At the same time, the fiber dust after filtration and separation is easily blown away by wind and other factors, which is not conducive to the transportation, production, processing and use of cellulose for the plant fibers and fiber dust after filtration and separation.

[0016] The present invention provides a dust filtering device for cellulose production, which has the following technical points and beneficial effects:

[0017] 1. The present invention is designed with devices such as a collecting basket, a heat insulation board and a separation bin, and the fiber cotton in the collecting basket and the fiber dust in the collecting bag are pressed together by the heat insulation board, so that the fiber cotton and the fiber dust are dried and extruded, and the fiber dust extruded in the collecting bag on the heat insulation board is taken out by opening the upper opening and closing sealing plate, and the dried and formed fiber dust is used for cellulose production, and then the heat insulation board and the fiber cotton in the collecting basket are taken out by taking the collecting basket out from the fiber filter tube, at which time the water vapor generated by the combustion of the ethanol solution condenses into a small amount of water droplets and flows into the collecting basket to moisten the fiber cotton, so as to prevent the formed fiber cotton from drying and expanding, and reduce the generation and adsorption of static electricity and dust, so as to facilitate the transportation and use of the fiber cotton in the next step of processing.

[0018] 2. The present invention designs devices such as a heat insulation board, a combustion stove and a separation chamber, and transports the volatilized combustible gas to the combustion stove through an air supply pipe and ignites and consumes it. At this time, the airtight spaces above and below the separation chamber with variable sizes generate negative pressure under gas consumption, so that the heat insulation board slides up and down respectively and fits into the collection basket and the top of the separation chamber respectively. When the combustion stove burns, the separation chamber conducts indirect heat to the collection basket and the collection bag, thereby avoiding overheating of the fiber cotton and fiber dust and reducing the quality. At the same time, the volatilization efficiency of the fiber dust and the ethanol solution in the fiber cotton in the collection bag and the collection basket is improved.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 10 The present invention provides a technical solution for a dust filtering device for cellulose production:

[0033] A dust filtering device for cellulose production, comprising a liquid storage tank 1, and a filter chamber 2 and a separation chamber 3 respectively fixedly mounted on the liquid storage tank 1, a sealing cover 9 is fixedly connected to the top of the filter chamber 2, a collecting box 12 is fixedly connected between the filter chamber 2 and the separation chamber 3, a fiber filter tube 101 is fixedly connected to one end of the liquid storage tank 1, a collecting basket 104 is movably connected to the inner side of the fiber filter tube 101, a filter cartridge 201 is movably mounted inside the filter chamber 2, a transmission shaft 204 is provided below the filter chamber 2, and the transmission shaft 2 04 runs through the bottom of the filter bin 2 and is fixedly connected to the filter cartridge 201. The upper part of the filter cartridge 201 is fixedly connected with a limit cover 202, and the limit cover 202 is provided with a limit groove 2021. The inner side of the filter cartridge 201 is movably mounted with two stirring shafts 203. The upper and lower ends of the stirring shaft 203 are fixedly connected with a rotating disk 2031, and the rotating disk 2031 at the upper end is movably connected with the limit groove 2021. A fixed tube 901 is provided between the two stirring shafts 203, and the fixed tube 901 is fixedly connected with the sealing cover 9.

[0034] As an embodiment of the present invention, Figures 1 to 10 As shown, the transmission shaft 204 is connected to one side of the fiber filter tube 101, a dust filter tube 13 is fixedly connected to one side of the filter bin 2, and the upper and lower sides of the dust filter tube 13 are provided with openings connected to the filter bin 2, and the upper opening of the dust filter tube 13 is provided with a copy plate 1301 fixedly connected to the filter bin 2, and the collection box 12 is connected to the upper opening of the dust filter tube 13;

[0035] During operation, the transmission shaft 204 is driven and rotated by the transmission belt 602. When the transmission shaft 204 drives the filter cartridge 201 to rotate in the filter bin 2, the closing valve 2041 opens the centrifugal valve plate under the centrifugal force generated by the rotation of the transmission shaft 204, so as to discharge the filtered and separated fiber cotton to the collection basket 104 below. Since the fixed pipe 901 is fixedly connected to the sealing cover 9, and the upper part of the filter cartridge 201 is fixedly connected with the limit cover 202, and the two rotating disks 2031 are movably arranged to mesh with the fixed pipe 901 through the limit groove 2021, when the filter cartridge 201 During the rotation, the two stirring shafts 203 revolve around the fixed tube 901 and rotate at the same time. The rotation of the filter cartridge 201 and the revolution of the two stirring shafts 203 in the filter cartridge 201 increase the centrifugal force generated by the rotation of the ethanol solution in the filter chamber 2. When the fixed tube 901 delivers the ethanol solution containing fiber cotton and fiber dust into the filter cartridge 201 (because the ethanol solution with an ethanol content of 70%-90% can better wet the fiber and is suitable for the processing of most organic fibers, has good compatibility, and is highly volatile, which is convenient for subsequent fiber processing), The stirring shaft 203 stirs and separates the fiber cotton and the fiber dust when rotating and revolving around the fixed tube 901, and filters and separates the fine fiber dust to the outside of the filter cartridge 201. At this time, the ethanol solution containing the fiber dust in the filter chamber 2 is simultaneously scooped into the upper opening of the dust filter tube 13 and the filter chamber 2 by the scooping plate 1301 under centrifugal rotation, and then the ethanol solution containing the fiber dust is scooped into the collection bag 1201 in the collection box 12 for collection. At this time, the ethanol solution scooped into the collection bag 1201 is discharged from the dust filter tube 13 under the discharge of the closed valve 2041. 3 flows out from the opening below which is connected to the filter bin 2. Since the fiber dust floats upward in the ethanol solution, most of the fiber dust is avoided from being discharged at the same time when the fiber cotton is discharged to the collecting basket 104 by closing the valve 2041. Even if a small amount of fiber dust is discharged at the same time when the fiber cotton is discharged onto the collecting basket 104, the fiber dust in the collecting basket 104 is filled into the liquid storage tank 1 through the ethanol solution. At this time, the ethanol solution containing the fiber dust in the liquid storage tank 1 will be pumped by the liquid guide pipe 11 to the feed hopper 4 for re-circulation, filtration and separation, thereby improving the filtering and separation effect of the fiber cotton and the fiber dust.

[0036] As an embodiment of the present invention, Figures 3 to 10As shown, a collecting bag 1201 is embedded and installed on the inner side of the collecting box 12, and bag edge strips 1208 are fixedly connected to the four corners of the collecting bag 1201, a closer 1202 is fixedly connected to one side of the collecting box 12, a closing plate 1205 is embedded and movably installed on the inner side of the closer 1202, and top buttons 1206 are embedded and installed on the upper and lower ends of one side of the closing plate 1205, and the top button 1206 is embedded and movably connected with the bag edge strip 1208, a sealing plate 1203 is embedded and movably installed on one side of the collecting box 12, and a fixing buckle 1204 for clamping and fixing with the collecting box 12 is fixedly connected to the sealing plate 1203, spring rods 1207 are embedded and movably installed on the upper and lower ends of the other side of the closing plate 1205, and the spring rod 1207 is fixedly connected to the collecting box 12, and a closing valve 2041 is embedded and installed on the inner side of the transmission shaft 204, and the closing valve 2041 includes a centrifugal valve plate and an elastic member;

[0037] During operation, the ethanol solution containing fiber dust is scooped into the collecting box 12 through the scooping plate 1301, and the fiber dust is collected by the collecting bag 1201 in the collecting box 12. Since one side of the collecting bag 1201 is provided with a sealant to prevent the ethanol solution from entering the upper part of the separation bin 3 to form an airtight space of variable size, when the fiber dust collected in the collecting bag 1201 is more, the resistance of the ethanol solution containing fiber dust to be scooped into the collecting bag 1201 through the scooping plate 1301 increases, thereby increasing the thrust of the ethanol solution containing fiber dust on the collecting bag 1201. When the fiber dust collected in the collecting bag 1201 is relatively full, the fiber dust collected in the collecting bag 1201 is discharged from the collecting bag 1201. When the thrust is large, the top button 1206 and the bag edge strip 1208 are disengaged, so that the collection bag 1201 filled with fiber dust falls into the upper part of the separation bin 3 to form an airtight space of variable size. At this time, the closing plate 1205 fits with the sealing plate 1203 under the elastic potential energy of the spring rod 1207 to separate and seal the collection box 12. Since the fixing buckle 1204 is fixedly engaged with the collection box 12, the sealing plate 1203 is prevented from opening. When a new collection bag 1201 needs to be added, the sealing plate 1203 is opened through the fixing buckle 1204, and the collection bag 1201 is put in, and then the sealing plate 1203 is closed. The sealing plate 1203 is closed and the fixing buckle 1204 is fixed to the collection box 12, thereby completing the replenishment of the collection bag 1201, and the closing plate 1205 pops out in the closer 1202 to trigger the operation of the signal transmission device in the closer 1202, and operates through the signal transmission device in the closer 1202 (the working process is that the pop-up action of the closing plate 1205 is used as a trigger signal, which triggers the signal transmission device in the closer 1202 to start working, and then transmits the control signal. This working principle belongs to the existing and mature technical means, which is common knowledge of those skilled in the art and will not be elaborated on here) , and sends the closing signal of the closing plate 1205 to the dual-axis servo motor 6 and the fiber filter tube 101. At this time, the dual-axis servo motor 6 stops operating, and the closing valve 2041 in the transmission shaft 204 closes the centrifugal valve plate under the elastic potential energy of the elastic member, so as to stop the transmission shaft 204 from transporting the filtered fiber cotton to the collection basket 104. Since an electromagnetic drive device is provided in the slide groove 103, and power is supplied to the electromagnetic drive device in the slide groove 103, the fixed slider 102 slides in the slide groove 103 through the operation of the electromagnetic drive device, and then the collection basket 104 slides in the fiber filter tube 101 to the bottom of the separation bin 3.

[0038] As an embodiment of the present invention, Figures 2 to 9As shown, both ends of the separation bin 3 are movably mounted with opening and closing sealing plates 301, the lower end heat insulation plate 303 forms an airtight space of variable size at the lower part of the separation bin 3 through the collecting basket 104, and the upper end heat insulation plate 303 forms an airtight space of variable size at the upper part of the separation bin 3 through the closing plate 1205 and the upper end opening and closing sealing plate 301, an air supply pipe 10 is provided on one side of the separation bin 3, and the airtight spaces of variable size at the upper and lower parts of the separation bin 3 are connected to the combustion stove 302 through the air supply pipe 10, the combustion stove 302 is fixedly connected to the middle part of the separation bin 3, the upper and lower ends of the combustion stove 302 are provided with heat insulation plates 303, and the heat insulation plates 303 are movably connected to the separation bin 3;

[0039] The inner sides of the fiber filter tube 101 and the collection basket 104 are respectively provided with filter holes, and one side of the collection basket 104 is provided with air holes, one side of the fiber filter tube 101 is provided with a slide groove 103, one side of the collection basket 104 is fixedly connected with a fixed slider 102, and the fixed slider 102 is movably connected with the slide groove 103 in an engaging manner;

[0040] During operation, when the collection bag 1201 filled with fiber dust falls into the airtight space of variable size formed above the separation bin 3, the collection basket 104 filled with fiber cotton slides in the fiber filter tube 101 to the bottom of the separation bin 3. Since the lower end heat insulation board 303 forms an airtight space of variable size below the separation bin 3 through the collection basket 104, and the airtight spaces of variable size above and below the separation bin 3 are connected to the combustion stove 302 through the air supply pipe 10, the collection bag 1201 filled with fiber dust and the collection basket 104 filled with fiber cotton volatilize into combustible gas in the airtight spaces of variable size above and below the separation bin 3 through the ethanol solution, and the volatilized combustible gas is transported to the combustion stove 302 through the air supply pipe 10. In the process, the combustible gas volatilized from the ethanol solution is consumed by igniting the combustion stove 302. At this time, the airtight spaces with variable sizes above and below the separation chamber 3 generate negative pressure under the consumption of gas, so that the insulation board 303 slides up and down respectively and fits into the collection basket 104 and the top of the separation chamber 3 respectively. Since the insulation board 303 is a heat-insulating material, it prevents the collection bag 1201 from overheating when it falls onto the insulation board 303 in the airtight space above. When the combustion stove 302 burns, the separation chamber 3 conducts indirect heat to the collection basket 104 and the collection bag 1201, thereby avoiding overheating of the fiber cotton and fiber dust and reducing the quality. At the same time, the volatilization efficiency of the fiber dust and the ethanol solution in the collection bag 1201 and the collection basket 104 is improved. When the combustion of the combustion stove 302 is carried out, carbon dioxide and water vapor are generated. Since the separation chamber 3 is airtightly arranged by the opening and closing sealing plate 301, the stability of the insulation plate 303 sticking to the collection basket 104 and the top of the separation chamber 3 is improved. Since the ethanol solution will cool the fiber cotton and fiber dust when it evaporates, when the insulation plate 303 fits and squeezes the fiber cotton in the collection basket 104 and the fiber dust in the collection bag 1201, the fiber cotton and fiber dust are dry and extruded. Since the content of ethanol solution in the dry extruded fiber cotton and fiber dust is low, the residual ethanol solution will also evaporate when it is taken out. When the extruded fiber cotton and fiber dust are taken out from the separation chamber 3, the upper opening and closing sealing plate 301 is opened to remove The fiber dust extruded in the collecting bag 1201 on the insulation board 303 is taken out, and then the dried and formed fiber dust is used for cellulose production, and gas is replenished inside the separation bin 3 for gas exchange. Secondly, the collection basket 104 is taken out from the fiber filter tube 101, and then the insulation board 303 in the collection basket 104 is taken out and the fiber cotton is taken out. At this time, the water vapor generated by the combustion of the ethanol solution condenses into a small amount of water droplets and flows into the collection basket 104 to moisten the fiber cotton to prevent the formed fiber cotton from drying and expanding, and reduce the generation and adsorption of static electricity and dust, so as to facilitate the transportation and use of the fiber cotton in the next processing step. Subsequently, the taken insulation board 303 is placed in the separation bin 3 by opening the middle opening and closing sealing plate 301 for reuse.

[0041] As an embodiment of the present invention, Figures 1 to 3 As shown, a fixed base 5 is provided below the filter bin 2 and is fixedly connected to the liquid storage tank 1. A dual-axis servo motor 6 is fixedly connected to one side of the fixed base 5. A transmission disc 601 is fixedly installed below the dual-axis servo motor 6, and a transmission belt 602 is connected between the transmission disc 601 and the transmission shaft 204.

[0042] During operation, the filter bin 2 and the dual-axis servo motor 6 are fixedly installed and supported by the fixed base 5. When in use, the transmission disk 601 is rotated by the operation of the dual-axis servo motor 6. Since a transmission belt 602 is provided between the transmission shaft 204 and the transmission disk 601, the transmission shaft 204 is rotated when the transmission belt 602 transmits the power. Through the transmission rotation of the transmission shaft 204, the filter cartridge 201 is rotated in the filter bin 2.

[0043] As an embodiment of the present invention, Figures 1 to 4 As shown, the upper part of the dual-axis servo motor 6 is transmission-connected with a centrifugal pump 7, and the centrifugal pump 7 is fixedly connected to the filter bin 2, and liquid guide tubes 11 are respectively provided on both sides of the centrifugal pump 7, the liquid guide tube 11 on one side of the centrifugal pump 7 is connected to the liquid storage tank 1, and the liquid guide tube 11 on the other side of the centrifugal pump 7 is connected to the feed hopper 4, the upper part of the sealing cover 9 is fixedly connected with the feed hopper 4, and one side of the feed hopper 4 is provided with an observation window 402, one side of the feed hopper 4 is provided with a feeding pipe 401, and the fixed pipe 901 is connected to the feeding pipe 401 through the feed hopper 4, and the upper part of the feed hopper 4 is fixedly connected with a condensation top 8;

[0044] During operation, when the dual-axis servo motor 6 is in operation, the centrifugal pump 7 is driven to operate through the dual-axis servo motor 6, and the operation of the centrifugal pump 7 further pumps the ethanol solution in the liquid storage tank 1 from the liquid guide tube 11 into the feed hopper 4, and then the ethanol pumped into the feed hopper 4 through the liquid guide tube 11 transports the fiber cotton in the feed hopper 4 through the feeding tube 401 and flushes it into the fixed tube 901, thereby flushing the fiber cotton containing fiber dust from the fixed tube 901 into the filter cartridge 201 for stirring and filtration, so as to filter and separate the fiber cotton and the fiber dust, and re-condense the volatilized ethanol water vapor through the condensation top 8, so as to avoid the waste of ethanol solution, and then seal the filter bin 2 through the sealing cover 9 to prevent the ethanol solution and the volatilized ethanol water vapor from overflowing, and observe the transportation status of the fiber cotton and the ethanol solution in the feed hopper 4 through the observation window 402.

[0045] Working principle: The centrifugal pump 7 is driven by the dual-axis servo motor 6 to operate, and the ethanol solution in the liquid storage tank 1 is pumped from the liquid guide tube 11 to the feed hopper 4 through the operation of the centrifugal pump 7, and the ethanol pumped into the feed hopper 4 through the liquid guide tube 11 transports the fiber cotton in the feed hopper 4 through the feed tube 401 and flushes it into the fixed tube 901, and the volatilized ethanol water vapor is condensed and re-condensed through the condensation top 8 to avoid the waste of ethanol solution, and the transmission disc 601 is rotated by the operation of the dual-axis servo motor 6, and the transmission shaft 204 is rotated by the transmission of the transmission belt 602, and the filter cartridge 201 is rotated in the filter bin 2 through the transmission rotation of the transmission shaft 204;

[0046] When the transmission shaft 204 drives the filter cartridge 201 to rotate in the filter chamber 2, the closing valve 2041 opens the centrifugal valve plate under the centrifugal force generated by the rotation of the transmission shaft 204. When the filter cartridge 201 rotates, the centrifugal force generated by the rotation of the filter cartridge 201 and the revolution of the two stirring shafts 203 in the filter cartridge 201 is increased. When the ethanol solution containing fiber cotton and fiber dust is transported to the filter cartridge 201 through the fixed pipe 901, the fiber cotton and the fiber dust are stirred and separated by the stirring shaft 203 when rotating and revolving around the fixed pipe 901. The fine fiber dust is separated and filtered out of the cartridge 201. At this time, the fiber dust outside the cartridge 201 is scooped into the upper opening of the dust filter tube 13 and the filter chamber 2 by the scooping plate 1301 under the rotation of the ethanol solution in the filter chamber 2, and then the fiber dust is scooped into the collection bag 1201 in the collection box 12 for collection. At this time, the ethanol solution scooped into the collection bag 1201 flows out from the lower opening of the dust filter tube 13 and the filter chamber 2 under the discharge flow of the closed valve 2041. The fiber cotton row after filtration and separation is placed on the collection basket 104 below through 2041;

[0047] The ethanol solution containing fiber dust is scooped into the collection box 12 through the scooping plate 1301. When the fiber dust collected in the collection bag 1201 is large, the resistance of the ethanol solution containing fiber dust to be scooped into the collection bag 1201 through the scooping plate 1301 increases, thereby increasing the thrust on the collection bag 1201. When the collection bag 1201 is full of fiber dust and the thrust is large, the top button 1206 and the bag edge strip 1208 are separated from the embedded connection state, thereby causing the collection bag 1201 filled with fiber dust to fall into the upper part of the separation bin 3 to form a large and small In the variable airtight space, at this time, the closing plate 1205 is sealed with the sealing plate 1203 under the elastic potential energy of the spring rod 1207, and the closing signal of the closing plate 1205 is sent to the dual-axis servo motor 6 and the fiber filter tube 101, and the dual-axis servo motor 6 stops operating, so that the closing valve 2041 in the transmission shaft 204 closes the centrifugal valve plate under the elastic potential energy of the elastic member, and at the same time, the fixed slider 102 slides in the slide groove 103, so that the collection basket 104 slides in the fiber filter tube 101 to the bottom of the separation bin 3;

[0048] When the collection bag 1201 filled with fiber dust falls into the airtight space of variable size formed above the separation chamber 3, the collection basket 104 filled with fiber cotton slides in the fiber filter tube 101 to the bottom of the separation chamber 3, and the fiber dust and fiber cotton containing ethanol solution are volatilized into combustible gas in the airtight space of variable size above and below the separation chamber 3, and the volatilized combustible gas is transported to the combustion stove 302 through the gas supply pipe 10 and ignited for consumption. At this time, the upper and lower parts of the separation chamber 3 are The airtight space with variable size generates negative pressure under gas consumption, so that the heat insulation board 303 slides up and down and fits into the collection basket 104 and the top of the separation chamber 3 respectively. When the combustion stove 302 burns, the separation chamber 3 conducts indirect heat to the collection basket 104 and the collection bag 1201, thereby avoiding overheating of the fiber cotton and fiber dust and reducing the quality. At the same time, the volatilization efficiency of the fiber dust and the ethanol solution in the fiber cotton in the collection bag 1201 and the collection basket 104 is improved. At this time, the combustion stove 3 is used to burn the fiber cotton and the fiber dust. The combustion of 02 produces carbon dioxide and water vapor to improve the stability of the insulation board 303 fitting into the collecting basket 104 and the top of the separation bin 3. When the insulation board 303 fits and squeezes the fiber cotton in the collecting basket 104 and the fiber dust in the collecting bag 1201, the fiber cotton and the fiber dust are dried and extruded. When the extruded fiber cotton and fiber dust are taken out from the separation bin 3, the upper opening and closing sealing plate 301 is opened to take out the extruded fiber dust in the collecting bag 1201 on the insulation board 303, and the dried fiber dust is used for cellulose production. Secondly, the collection basket 104 is taken out from the fiber filter tube 101, and the insulation board 303 and the fiber cotton in the collection basket 104 are taken out. At this time, the water vapor generated by the combustion of the ethanol solution condenses into a small amount of water droplets and flows into the collection basket 104 to moisten the fiber cotton, so as to prevent the formed fiber cotton from drying and expanding, and reduce the generation and adsorption of static electricity and dust, so as to facilitate the transportation and use of the fiber cotton in the next processing step.
