Description

Technical Field

[0001] The present invention relates to the technical field of centrifugal crushing, and particularly to a biomass particle processing device and a processing method based on plant fiber livestock and poultry manure water. Background Art

[0002] Biomass particles are a kind of solid fuel made from biomass raw materials, mainly used to replace traditional fossil fuels, and belong to a kind of renewable energy.

[0003] The main raw materials of biomass particles include:

[0004] Agricultural and forestry waste: such as wood chips, straw, rice husks, branches, fruit shells, etc.;

[0005] Energy crops: such as switchgrass, miscanthus and other specially planted energy plants;

[0006] Other organic waste: such as food processing residues, garden waste, livestock and poultry manure water, etc.

[0007] The production process of biomass particles:

[0008] Crushing: crushing the raw materials into fine particles;

[0009] Drying: reducing the moisture content of the raw materials;

[0010] Compression molding: under high temperature and high pressure, compressing the raw materials into cylindrical particles with a diameter of 6 - 10 mm and a length of 10 - 30 mm through a granulator;

[0011] Cooling and packaging: cooling and then sealing the package to prevent moisture absorption.

[0012] Among them, when processing biomass particles based on plant fiber livestock and poultry manure water, the livestock and poultry manure water is dehydrated by a filter press to obtain a cake, and the cake is transported and put into a centrifugal crusher to crush the plant fiber in the livestock and poultry manure water, preventing the fiber from being too long and causing difficulties in pelletizing. After the crushed fiber residue is mixed with the filter residue, it is transported to an external granulator to finally form high - calorific - value biomass particles.

[0013] When the plant fiber in the cake put into the centrifugal crusher is crushed, the plant fiber is undigested and has a certain toughness, resulting in high energy consumption and a relatively long crushing time during centrifugal crushing, which delays pelletizing.

[0014] In view of this, we propose a biomass particle processing device and a processing method based on plant fiber livestock and poultry manure water. Summary of the Invention

The bottom ends of the plurality of connecting rods A are respectively fixedly connected to the spiral blade;

[0027] A motor is arranged at the transmission end of the centrifugal crusher body. A protective frame is arranged at the output of the motor. The motor is in transmission cooperation with the connecting ring A through a driving structure;

[0028] The driving structure includes pulley A, pulley B, a crank, a movable block and a slideway. Pulley A is arranged on the transmission shaft of the motor. Pulley B is rotatably arranged on the protective frame. Pulley A and pulley B are in transmission cooperation through a transmission belt. A transmission rod is fixedly arranged on pulley B. The transmission rod passes through the protective frame. The extending end of the transmission rod is fixedly provided with a turntable. One end of the crank is eccentrically rotatably connected to the turntable through a rotating shaft.

[0030] An extension plate is fixedly arranged at the side end of the top of the movable block. An expansion rod B is arranged between the extension plate and annular cover plate A;

[0033] Preferably, a rubber pad is fixedly arranged at the abutting end of the bolt. The rubber pad is in contact fit with the outer peripheral surface of the central shaft.

[0034] Processing method of the biomass particle processing device based on plant fiber livestock and poultry manure water, centrifugal crushing process:

[0035] S1. The livestock and poultry manure water cake after being dewatered by a filter press is conveyed by a conveyor and put in from the inlet of the inner ring plate;

[0036] S2. The motor starts. The motor drives the high-speed rotor inside the centrifugal crusher body to work in the crushing cavity through a gear set. And the motor drives the pulley A to rotate, drives the pulley B to rotate through a transmission belt, and the transmission rod and the turntable rotate accordingly, causing the crank to drive. Cooperating with the rotating shaft and the spherical plain bearing to drive the movable block to move, and cooperating with the extension plate and the telescopic rod B, the movable block is kept moving longitudinally. Due to the inclined settings of the movable block and the slideway, the movable block moves longitudinally back and forth, driving the two slideways to rotate back and forth within a small range, thereby driving the connecting ring A to rotate back and forth within a small range. The connecting ring A rotates back and forth within a small range relative to the annular track under the action of the slider. The connecting block, the telescopic rod A, the connecting ring B and the connecting rod A rotate back and forth within a small range accordingly, causing the spiral blade to rotate back and forth within a small range. The reciprocating small-range rotation of the spiral blade generates dynamic vibration on the cake on the spiral blade, causing the cake to fall along the spiral blade; at the same time, with the reciprocating small-range rotation of the spiral blade, the non-threaded ends of the two screws slide back and forth along the guide groove A and the guide groove B respectively. The setting of the spiral line causes the two screws to have a height change when sliding along the guide groove A and the guide groove B, and cooperating with the telescopic rod A causes the spiral blade to rotate and lift at the same time; when the spiral blade changes from rising to falling, the instantaneous separation reduces the frictional force between the cake and the spiral blade in contact, which helps the cake to fall along the spiral blade. When the spiral blade changes from falling to rising, the instantaneous lifting force makes the acting force between the cake and the spiral blade in contact larger, which can disperse the cake and helps the cake to be dispersed.

[0037] S3. At the same time, the high-temperature steam generated by the steam generator body is transported from the connecting pipe to the cavity between the outer ring plate and the inner ring plate. The high-temperature steam in the cavity enters the inner ring plate through the air gap, and the high-temperature steam softens the fibers in the cake.

[0038] S4. The materials that have been shaken and softened by the feeding structure enter the centrifugal crusher body through the hopper, are crushed in the crushing cavity, and the crushed materials are discharged from the bottom outlet of the centrifugal crusher body.

[0039] Compared with the prior art, the beneficial effects of the present invention are:

[0040] 1. By setting the steam generator body, the connecting pipe, the outer ring plate, the inner ring plate, the annular cover plate A, the annular cover plate B and the air gap, the present invention has the advantage of introducing steam into the area passing through the cake to soften the plant fibers in the cake with steam, which helps the subsequent crushing of the plant fibers. It solves the problems that the energy consumption is relatively high and the crushing time is relatively long when centrifugally crushing the too-long plant fibers in the cake, delaying granulation.

[0041] 2. By providing a transmission structure, a feeding structure, and a driving structure, the present invention has the advantages that the connecting ring A is driven to rotate reciprocally within a small range, causing the spiral blade to rotate reciprocally within a small range. The reciprocally rotating spiral blade generates dynamic vibration on the cake-shaped object that falls on the spiral blade, causing the cake-shaped object to fall along the spiral blade, thus solving the problem that the cake-shaped object is not easily dropped along the spiral blade.

[0042] 3. By providing a guide groove A, a guide groove B, a fixing block, and a screw rod, when the spiral blade changes from ascending to descending, the instantaneous separation reduces the frictional force between the cake-shaped object and the spiral blade, facilitating the cake-shaped object to fall along the spiral blade. When the spiral blade changes from descending to ascending, the instantaneous lifting force increases the acting force between the cake-shaped object and the spiral blade, which can disperse the cake-shaped object and is conducive to the dispersion of the cake-shaped object.

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0062] Please refer to Figures 1 to 5 , an embodiment provided by the present invention: a biomass pellet processing device based on plant fiber livestock and poultry manure water, including a centrifugal crusher body 100 and a steam generator body 500;

[0063] The centrifugal crusher body 100 is suitable for crushing the plant fiber of livestock and poultry manure water. The high-speed rotor of the centrifugal crusher body 100 is arranged in the crushing chamber. The high-speed rotor is equipped with hammers, blades or tooth plates, and is connected to the motor 200 through the main shaft. The motor 200 drives the high-speed rotor to rotate through gears. The crushing chamber is set as an annular or conical cavity, and its inner wall is provided with wear-resistant liners or impact plates to enhance the impact crushing effect;

[0064] The steam generator body 500 uses an electric heating type, and its resistance element is a stainless steel or nickel-chromium alloy electric heating tube, and the electric heating tube is immersed in water for heating; it includes a heat exchanger, a water circulation system, a steam-water separation device, a pressure control and safety system, a water treatment and sewage discharge system, etc. The steam generator body 500 is a publicly known technology that heats water to convert it into steam, and the high-temperature steam generated by the steam generator body 500 is discharged for use.

[0065] The feeding end of the centrifugal crusher body 100 is provided with a feeding structure 300;

[0066] The feeding structure 300 includes an outer ring plate 301 and an inner ring plate 302. Both the outer ring plate 301 and the inner ring plate 302 are fixedly arranged at the feeding end of the centrifugal crusher body 100. The outer ring plate 301 covers the inner ring plate 302, and a cavity is formed between the outer ring plate 301 and the inner ring plate 302. An annular cover plate A303 is fixedly arranged at the upper end of the cavity between the outer ring plate 301 and the inner ring plate 302, and an annular cover plate B304 is fixedly arranged at the lower end of the cavity. A plurality of air slots 3021 are formed on the circumferential surface of the inner ring plate 302, and the air slots 3021 communicate with the cavity.

[0067] The air outlet end of the steam generator body 500 is connected to the air inlet end on the outer ring plate 301 through a connecting pipe 400. The steam generated by the steam generator body 500 is discharged into the cavity through the connecting pipe 400, and the high-temperature steam in the cavity enters the inner ring plate 302 through the air slots 3021 to soften the fibers in the cake-like material.

[0068] A hopper 305 is fixedly arranged at the bottom of the inner cavity of the inner ring plate 302. The hopper 305 corresponds to the feeding port of the centrifugal crusher body 100. The material passing through the inner ring plate 302 enters the crushing cavity of the centrifugal crusher body 100 through the hopper 305 for crushing; a guide ring 306 is fixedly arranged at the top of the hopper 305. The inner side of the guide ring 306 is set as an annular inclined surface, and the annular inclined surface corresponds to the inner circumference of the hopper 305. When the material passes through the annular inclined surface of the guide ring 306, it passes smoothly, which helps the material to fall.

[0069] By setting the steam generator body 500, the connecting pipe 400, the outer ring plate 301, the inner ring plate 302, the annular cover plate A303, the annular cover plate B304 and the air slots 3021, the present invention has the advantage of introducing steam into the area passing through the cake-like material and using the steam to soften the plant fibers in the cake-like material, which helps the subsequent treatment of crushing the plant fibers, and solves the problems that the energy consumption is relatively high and the crushing time is relatively long when centrifugally crushing the too long plant fibers in the cake-like material, which delays pelletizing.

[0070] Please refer to Figures 1 to 4 、 Figures 6 to 9 、 Figure 11 and Figure 12, an embodiment provided by the present invention: a biomass pellet processing device based on plant fiber livestock and poultry manure water, a feeding structure 700 is arranged inside the inner ring plate 302;

[0071] The feeding structure 700 includes a spiral blade 702, the spiral blade 702 is movably arranged inside the inner ring plate 302, a central shaft 701 is inserted through the middle of the spiral blade 702, and the peripheral surface of the central shaft 701 is fixedly connected to the inner spiral side of the spiral blade 702; the cake-shaped object put into the inner ring plate 302 falls spirally through the spiral blade 702, increasing the passing path of the cake-shaped object, thereby increasing the contact time between the cake-shaped object and the steam, which helps to soften the plant fiber. The top end of the central shaft 701 is set in a conical shape, and the put-in cake-shaped object contacts the tip of the central shaft 701 and is knocked open and falls into the inner ring plate 302.

[0072] The spiral blade 702 is connected with a transmission structure 600;

[0073] The transmission structure 600 includes a connecting ring A601, an annular track 602 and a connecting ring B606. The annular track 602 is fixedly arranged on the annular cover plate A303. A plurality of sliders 603 are fixedly arranged in an annular array on the bottom side of the connecting ring A601. The sliders 603 are slidably matched with the annular track 602. A plurality of connecting blocks 604 are fixedly arranged in an annular array on the inner side of the connecting ring A601. The plurality of connecting blocks 604 are respectively connected to the connecting ring B606 through telescopic rods A605. A plurality of connecting rods A607 are fixedly arranged in an annular array on the bottom side of the connecting ring B606. The bottom ends of the plurality of connecting rods A607 are respectively fixedly connected to the spiral blade 702. The connection positions of the plurality of connecting rods A607 with the spiral blade 702 are different. Therefore, the lengths of the plurality of connecting rods A607 are selected and adjusted according to the connection positions with the spiral blade 702. When the connecting ring A601 rotates reciprocally within a small range relative to the annular track 602 through the sliders 603, the connecting blocks 604, the telescopic rods A605, the connecting ring B606 and the connecting rods A607 rotate reciprocally within a small range accordingly, causing the spiral blade 702 to rotate reciprocally within a small range. The reciprocally rotating spiral blade 702 generates dynamic vibration on the cake-shaped object falling on the spiral blade 702, so that the cake-shaped object falls along the spiral blade 702.

[0074] A motor 200 is arranged at the transmission end of the centrifugal crusher body 100, and the motor 200 is selected and used by professional technical personnel according to the actual situation; a protective frame 900 is arranged at the motor 200, and the motor 200 is in transmission cooperation with the connecting ring A601 through a driving structure 800;

[0075] The drive structure 800 includes pulley A801, pulley B802, crank 806, movable block 809 and slideway 810. Pulley A801 is arranged on the transmission shaft of the motor 200. Pulley B802 is rotatably arranged on the protective frame 900. Pulley A801 and pulley B802 are in transmission cooperation through the transmission belt 803. The motor 200 drives pulley A801 to rotate, and drives pulley B802 to rotate through the transmission belt 803. Moreover, the motor 200 drives the high-speed rotor in the centrifugal crusher body 100 to work in the crushing cavity through the gear set, and the two drives are carried out synchronously. A transmission rod 804 is fixedly arranged on pulley B802. The transmission rod 804 passes through the protective frame 900. The extending end of the transmission rod 804 is fixedly provided with a turntable 805. One end of the crank 806 is eccentrically rotatably connected to the turntable 805 through a rotating shaft 807. The other end of the crank 806 is rotatably connected to the top of the movable block 809 through a spherical plain bearing 808. The two slideways 810 are respectively fixedly arranged on the outer peripheral surface of the connecting ring A601. The movable block 809 and the two slideways 810 are inclined. The movable block 809 is in sliding fit with the sliding cavity formed between the two slideways 810. A extension plate 811 is fixedly arranged on the side end of the top of the movable block 809. An expansion link B812 is arranged between the extension plate 811 and the annular cover plate A303. When pulley B802 rotates, the transmission rod 804 and the turntable 805 rotate therewith, causing the crank 806 to transmit power. Cooperating with the rotating shaft 807 and the spherical plain bearing 808 to drive the movable block 809 to move. Cooperating with the extension plate 811 and the expansion link B812, the movable block 809 is kept moving longitudinally. Due to the inclined arrangement of the movable block 809 and the slideways 810, the movable block 809 moves longitudinally back and forth, driving the two slideways 810 to rotate back and forth within a small range, thereby driving the connecting ring A601 to rotate back and forth within a small range.

[0076] Fixed blocks 703 are respectively fixedly arranged on the outer sides of both ends of the spiral blade 702. Screws 704 are threadedly penetrated through the fixed blocks 703. The non-threaded ends of the two screws 704 are respectively in sliding fit with a guide groove A3022 and a guide groove B3023 formed on the inner peripheral surface of the inner ring plate 302. When the screws 704 are rotated, the screws 704 move relative to the fixed blocks 703 to adjust the position, facilitating the installation of the spiral blade 702 inside the inner ring plate 302. Both the guide groove A3022 and the guide groove B3023 are arranged in a spiral shape. Along with the reciprocating rotation of the spiral blade 702 within a small range, the non-threaded ends of the two screws 704 slide back and forth along the guide groove A3022 and the guide groove B3023 respectively. The spiral arrangement causes the two screws 704 to generate a height change when sliding along the guide groove A3022 and the guide groove B3023, cooperating with the expansion link A605 to cause the spiral blade 702 to rotate and lift at the same time.

[0077] By providing a transmission structure 600, a feeding structure 700, and a driving structure 800, the present invention has the advantages that the connecting ring A601 is driven to rotate reciprocally within a small range, causing the spiral blade 702 to rotate reciprocally within a small range. The reciprocally rotating spiral blade 702 generates a dynamic vibration on the cake-shaped object that falls on the spiral blade 702, enabling the cake-shaped object to fall along the spiral blade 702, thus solving the problem that the cake-shaped object is not easily fallen on the spiral blade 702.

[0078] By providing a guide groove A3022, a guide groove B3023, a fixing block 703, and a screw 704, when the spiral blade 702 changes from rising to falling, the instantaneous separation reduces the frictional force between the cake-shaped object and the spiral blade 702, which helps the cake-shaped object to fall along the spiral blade 702. When the spiral blade 702 changes from falling to rising, the instantaneous lifting force increases the acting force between the cake-shaped object and the spiral blade 702, which can disperse the cake-shaped object and helps the cake-shaped object to be dispersed.

[0079] Please refer to Figure 6 and Figure 10 , an embodiment provided by the present invention: a biomass particle processing device based on plant fiber livestock and poultry manure water. A plurality of connecting rods B608 are fixedly arranged on the inner circumferential surface of the connecting ring A601 in an annular array. The connecting rods B608 do not affect the input of the cake-shaped object. A collar 609 is fixedly arranged between the plurality of connecting rods B608. The collar 609 is sleeved and matched with the central shaft 701. The central shaft 701 moves along the collar 609. A bolt 610 is threadedly penetrated through the collar 609. The bolt 610 is in abutting fit with the outer circumferential surface of the central shaft 701; a rubber pad is fixedly arranged at the abutting end of the bolt 610. The rubber pad is in contact fit with the outer circumferential surface of the central shaft 701. When the device is not used for a long time, the staff twists the bolt 610 until the rubber pad abuts against the outer circumferential surface of the central shaft 701, thereby clamping the central shaft 701, so that the central shaft 701 and the spiral blade 702 are kept stable in the non-use state and share the acting force brought by the self-gravity of the central shaft 701 and the spiral blade 702.

[0080] Please refer to Figures 1 to 12 , a processing method of a biomass particle processing device based on plant fiber livestock and poultry manure water, centrifugal crushing process:

[0081] S1. The livestock and poultry manure water cake-shaped object after being dewatered by a filter press is conveyed by a conveyor and then input from the inlet of the inner ring plate 302;

[0082] S2. The motor 200 starts. The motor 200 drives the high-speed rotor in the centrifugal crusher body 100 to work in the crushing chamber through a gear set. And the motor 200 drives the pulley A 801 to rotate, drives the pulley B 802 to rotate through the transmission belt 803. The transmission rod 804 and the turntable 805 rotate accordingly, causing the crank 806 to drive. Cooperating with the rotating shaft 807 and the spherical plain bearing 808 to drive the movable block 809 to move. Cooperating with the extension plate 811 and the telescopic rod B 812, the movable block 809 is kept moving longitudinally. Due to the inclined settings of the movable block 809 and the slideway 810, the movable block 809 moves longitudinally back and forth, driving the two slideways 810 to rotate back and forth within a small range, thereby driving the connecting ring A 601 to rotate back and forth within a small range. The connecting ring A 601 rotates back and forth within a small range relative to the annular track 602 under the action of the slider 603. The connecting block 604, the telescopic rod A 605, the connecting ring B 606 and the connecting rod A 607 rotate back and forth within a small range accordingly, causing the spiral blade 702 to rotate back and forth within a small range. The reciprocating small-range rotation of the spiral blade 702 generates dynamic vibration on the cake on the spiral blade 702, making the cake fall along the spiral blade 702. At the same time, with the reciprocating small-range rotation of the spiral blade 702, the non-threaded ends of the two screws 704 slide back and forth along the guide groove A 3022 and the guide groove B 3023 respectively. The spiral line setting causes the two screws 704 to have a height change when sliding along the guide groove A 3022 and the guide groove B 3023. Cooperating with the telescopic rod A 605, the spiral blade 702 rotates and rises and falls at the same time. When the spiral blade 702 changes from rising to falling, the instantaneous separation reduces the frictional force between the cake and the spiral blade 702, which helps the cake to fall along the spiral blade 702. When the spiral blade 702 changes from falling to rising, the instantaneous lifting force makes the acting force between the cake and the spiral blade 702 larger, which can disperse the cake and helps the cake to be dispersed.

[0083] S3. At the same time, the high-temperature steam generated by the steam generator body 500 is transported from the connecting pipe 400 to the cavity between the outer ring plate 301 and the inner ring plate 302. The high-temperature steam in the cavity enters the inner ring plate 302 through the air gap 3021, and the high-temperature steam softens the fibers in the cake.

[0084] S4. The materials that have been dispersed and softened by the feeding structure 300 enter the centrifugal crusher body 100 through the hopper 305, are crushed in the crushing chamber, and the crushed materials are discharged from the bottom outlet of the centrifugal crusher body 100.
