Description

Technical Field

[0001] The invention belongs to the technical field of garbage incineration, and particularly relates to a semi-dry lime slurry preparation device for garbage treatment. Background Art

[0002] Garbage disposal refers to the process of harmless, resource-based and volume-reduced solid waste generated in human daily life and production. At present, the commonly used garbage disposal method is garbage incineration, that is, through appropriate thermal decomposition, combustion, melting and other reactions, the garbage is oxidized at high temperature to reduce its volume and become residue or molten solid matter. Garbage incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals, organic pollutants, etc. from being discharged into the environmental medium again. Recycling the heat generated by garbage incineration can achieve the purpose of waste resource utilization. Garbage incineration is an older traditional method of garbage disposal. Since the garbage is treated by incineration, the reduction effect is significant, land is saved, various pathogens can be eliminated, and toxic and harmful substances can be converted into harmless substances, so garbage incineration has become one of the main methods of urban garbage disposal. Modern garbage incinerators are equipped with good smoke purification devices to reduce air pollution.

[0003] During the process of waste incineration, the acidic flue gas generated needs to be treated to avoid environmental pollution, and lime slurry is generally used for treatment. At present, when the lime slurry preparation tank system is started, water is added from the top of the tank. After reaching a certain weight, lime is added for stirring. The slaked lime is slightly soluble in water, and after being made into lime slurry, it is a suspension. When the stirring stops or is insufficient, it will settle at the bottom of the tank. It is easy to clog the pipeline when the slurry is discharged into the lime slurry storage tank for a long time. In particular, if the concentration of the lime slurry is increased due to high indicators, the preparation tank and the lime slurry discharge filter will be more easily blocked, increasing the frequency of cleaning.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0026] The semi-dry lime slurry preparation device for garbage disposal of the present invention discharges water into the pulping tank from different positions by arranging a water inlet mechanism, and after the lime material is fed into the pulping tank by the feeding mechanism, the lime material is uniformly stirred by the stirring mechanism, and during the stirring process, the deposited lime material remaining at the bottom of the pulping tank is scraped up and stirred for a second time by a scraping mechanism connected to the stirring mechanism, thereby effectively preventing the bottom from settling, and the remaining sediment is cleaned by a cleaning mechanism installed at the bottom end of the pulping tank, further eliminating the sediment at the bottom of the pulping tank, and effectively preventing the subsequent clogging of the pulping tank and affecting the lime slurry preparation efficiency.

[0027] refer to Figures 1 to 8 The present invention provides a semi-dry lime slurry preparation device for garbage disposal, comprising a pulping tank 1, wherein a water inlet mechanism 2 and a feeding mechanism 3 are respectively installed on the side wall and the top of the pulping tank 1, wherein a stirring mechanism 4 is installed inside the pulping tank 1, and a scraping mechanism 5 is also installed at the bottom of the stirring mechanism 4, wherein the scraping mechanism 5 is connected to the stirring mechanism 4 through a connecting piece 6, and is used to scrape off the lime slurry remaining at the bottom of the pulping tank 1, and a cleaning mechanism 7 located at the bottom of the pulping tank 1 is also connected to the outside of the water inlet mechanism 2, and the cleaning mechanism 7 is used to cooperate with the scraping mechanism 5 to clean the inner wall of the pulping tank 1; The stirring mechanism 4 includes a driving seat 401 installed at the top of the pulping tank 1, the bottom of the driving seat 401 is connected to a driving shaft 402 inserted into the pulping tank 1, the bottom of the driving shaft 402 is connected to an agitator 403, the outer wall shape of the agitator 403 matches the inner shape of the bottom of the pulping tank 1, and the scraping mechanism 5 is installed on the outer wall of the agitator 403 to scrape off the sediment remaining on the inner wall of the pulping tank 1 when the agitator 403 rotates. The pulping tank 1 includes a cylindrical area connected up and down. 101 and a funnel area 102, the water inlet mechanism 2 comprises a plurality of water inlet rings 201 installed on the inner wall of the cylindrical area 101, the water inlet ring 201 at the top is connected to an external water pipe for inputting water, a plurality of the water inlet rings 201 are evenly arranged up and down along the inner wall of the pulping tank 1, a plurality of sprinklers 202 are evenly installed between adjacent water inlet rings 201, a plurality of nozzles 203 are evenly connected to the outer wall of each water inlet ring 201, and the sprinklers 202 and the nozzles 203 are staggered.

[0028] In this embodiment, during the preparation of lime slurry, the pre-prepared lime material enters the pulping tank 1 through the feeding mechanism 3, the water inlet mechanism 2 discharges the water for preparing lime slurry from the side wall of the pulping tank 1, and cooperates with the stirring mechanism 4 to stir and mix the lime material and water to obtain a uniformly mixed lime slurry. During the stirring process, the water is discharged from the side wall of the pulping tank 1, which can effectively reduce the sedimentation and blockage at the bottom of the pulping tank 1 compared with the discharge from the top. In addition, during the preparation of lime slurry in the pulping tank 1, even if there is solid sedimentation and residue at the bottom of the pulping tank 1, the stirring mechanism 4 rotates and drives the scraping mechanism 5 to rotate through the connecting piece 6, thereby scraping up the sediment remaining at the bottom of the pulping tank 1, and cooperates with the stirring mechanism 4 to achieve secondary stirring and mixing of the sediment, thereby reducing the sedimentation inside the pulping tank 1. At the same time, the cleaning mechanism 7 is cooperated to spray water to clean the inside of the pulping tank 1, and further cooperates with the scraping mechanism 5 to improve the removal effect of the sediment inside the pulping tank 1.

[0029] It should be noted that the feeding mechanism 3 adopts a screw feeder in the prior art. This solution does not involve specific improvements to the feeding, which will not be repeated here.

[0030] Specifically, a plurality of water inlet rings 201 are installed on the inner wall of the cylindrical area 101 at the top of the pulping tank 1, and the top water inlet ring 201 is connected to an external water pipe to input water, and adjacent water inlet rings 201 are connected by water sprinklers 202, so that water can enter different water inlet rings 201 and water sprinklers 202 from top to bottom in sequence, and the water inlet ring 201 sprays water into the pulping tank 1 in different directions through multiple external nozzles 203, and the water sprinklers 202 spray water between adjacent water inlet rings 201, so that the positions where the water is sprayed are more dispersed in the entire pulping tank 1, which is conducive to the water entering the pulping tank 1 and the lime material being fully mixed together. The driving seat 401 drives the driving shaft 402 to rotate through the internal motor, and drives the agitator 403 to rotate through the driving shaft 402, so that the lime material entering the pulping tank 1 is fully mixed with water, thereby preventing the lime material from being unevenly mixed and sinking to the bottom during the mixing process.

[0031] In some embodiments, both ends of the water sprinkler 202 are conductively connected to the water inlet ring 201 through a telescopic pipe 206, a fixed cylinder 204 is installed on the outer wall of the cylindrical area 101, a first electric push rod 205 is installed inside the fixed cylinder 204, and the end of the first electric push rod 205 is connected to the water sprinkler 202 through a connecting head 207 to adjust the height of the water sprinkler 202 inside the pulping tank 1, and the connection between the fixed cylinder 204 and the cylindrical area 101 is set as a conductive opening, and the first electric push rod 205 pushes the connecting head 207 to move up and down along the opening.

[0032] In this embodiment, since both ends of the sprinkler 202 are installed between adjacent water inlet rings 201 through telescopic pipes 206, in order to further adjust the position of the sprinkler 202, a fixed cylinder 204 is installed on the outer wall of the cylindrical area 101, and the first electric push rod 205 drives the connecting head 207 to move up and down along the opening connected between the fixed cylinder 204 and the cylindrical area 101, so that the first electric push rod 205 installed in the fixed cylinder 204 drives the sprinkler 202 to move up and down, and the telescopic pipe 206 also moves up and down accordingly, thereby realizing the height adjustment of the sprinkler 202, so that the sprinklers 202 between adjacent water inlet rings 201 can spray water at different heights, further enhancing the mixing effect of the lime material and reducing the uneven mixing.

[0033] Furthermore, the fixed cylinder 204 disposed on the outer wall of the cylindrical area 101 can also facilitate cleaning of internal residues by providing an opening at the bottom thereof.

[0034] In some other embodiments, the cleaning mechanism 7 includes a plurality of inclined water pipes 701 installed on the inner wall of the funnel area 102 and evenly arranged radially, and a filling block 710 located on the surface of the funnel area 102 is arranged between adjacent inclined water pipes 701, the upper surface of the filling block 710 is flush with the upper surface of the inclined water pipe 701 and forms a funnel inclined plane, the funnel inclined plane is parallel to the surface of the funnel area 102, a central seat 702 is installed at the center of the funnel area 102, an isolation groove 703 is installed inside the central seat 702, the bottom of the isolation groove 703 passes through the funnel area 102 to input an external cleaning water source, each of the inclined water pipes 701 is conductively connected to the isolation groove 703 inside the central seat 702, the outer end of the inclined water pipe 701 is conductively connected to a movable nozzle 705 with a nozzle through a connecting seat 704, and the surface of the movable nozzle 705 is conductively connected to the The surfaces of the funnel inclined planes are parallel, and in the direction perpendicular to the funnel inclined plane, the height of the surface of the movable nozzle 705 is lower than the height of the funnel inclined plane. The movable nozzle 705 is rotatably connected to the connecting seat 704 through a sealing bearing 706. The portion of the movable nozzle 705 located at the inclined water pipe 701 is conductively connected to the inclined water pipe 701, so that water flows from the isolation groove 703 into the inclined water pipe 701 and then enters the movable nozzle 705. The movable nozzle 705 is inserted into one end of the central seat 702 for blocking and is installed with a driven gear 707. A rotating shaft 708 is installed at the center of the central seat 702. A driving gear 709 is connected to the top of the rotating shaft 708. The driving gear 709 is transmission-connected to each of the driven gears 707 to drive the movable nozzle 705 to rotate. The rotating shaft 708 is driven by a stepper motor installed at the bottom of the funnel area 102.

[0035] In this embodiment, on the one hand, the water source is input from the side of the cylindrical area 101 of the pulping tank 1 through the water inlet mechanism 2, and on the other hand, the water source can be input from the funnel area 102 of the pulping tank 1 by using the cleaning mechanism 7. In conjunction with the water inlet mechanism 2, water is input from the side of the pulping tank 1, thereby achieving a dispersed entry of the water source inside the pulping tank 1, which can improve the mixing effect of the lime slurry inside the pulping tank 1; on the other hand, after the pulping tank 1 completes the lime slurry preparation process, the cleaning mechanism 7 is used to clean the sediment remaining on the inner wall of the funnel area 102 of the pulping tank 1 to avoid accumulation that affects the subsequent lime slurry preparation efficiency.

[0036] Specifically, when lime slurry needs to be prepared inside the pulping tank 1, on the one hand, water is discharged from the cylindrical area 101 of the inner wall of the pulping tank 1 through the water inlet ring 201 and the water sprayer 202, and on the other hand, the water is directly sprayed upward from the bottom of the funnel area 102 through the cleaning mechanism 7, which can not only speed up the water intake efficiency, but also realize multi-directional water intake. Specifically, after the external water source is input into the isolation groove 703 inside the central seat 702, the water source enters the inclined water pipe 701 installed on the surface of the funnel area 102, and the inclined water pipe 701 is connected to the movable nozzle 705 through the connecting seat 704, and the movable nozzle 705 is rotatably connected to the connecting seat 704 through the sealing bearing 706 to ensure that the movable nozzle 705 can rotate along the connecting seat 704. The driving gear 709 is driven to rotate by the rotating shaft 708 installed in the central seat 702. Since the driving gear 709 is connected to the driven gear 707 at the end of the movable nozzle 705, the driving gear 709 drives the driven gear 707 to rotate, and the driven gear 707 is connected to the movable nozzle 705, thereby driving the movable nozzle 705 to rotate, so that the movable nozzle 705 can spray water in different directions into the funnel area 102 after rotating, which can accelerate the stirring and mixing of the lime material in the funnel area 102, and the water flow sprayed from the movable nozzle 705 can perform secondary washing on the surface of the funnel area 102, further reducing the residue on the surface of the funnel area 102. The entire cleaning mechanism 7 can not only cooperate with the water inlet mechanism 2 to achieve drainage in different directions inside the pulping tank 1 to improve the uniform mixing degree of the lime slurry, but also after the preparation of the lime slurry is completed, the cleaning mechanism 7 can also be used to flush the inside of the pulping tank 1 to prevent residue from appearing inside the pulping tank 1 and affecting the subsequent preparation process of the lime slurry.

[0037] Exemplarily, the driving gear 709 and the driven gear 707 use a bevel gear transmission structure to achieve meshing transmission.

[0038] In some further embodiments, a plurality of water dividers 7051 are evenly arranged on both sides of the surface of the movable nozzle 705, and an upper diverter pipe 7052 located on both sides of the movable nozzle 705 is installed on the top of the water divider 7051, and lower diverter pipes 7053 located on both sides of the movable nozzle 705 are conductively connected on both sides of the bottom of the water divider 7051, and the structures of the upper diverter pipe 7052 and the lower diverter pipe 7053 in the plurality of water dividers 7051 installed on each of the movable nozzle 705 are not exactly the same, and after the stepper motor rotates, the lower diverter pipe 7053 at the bottom of the water divider 7051 contacts the inner wall of the funnel area 102, and starts reverse rotation.

[0039] In this embodiment, by providing a rotatable movable nozzle 705, water can be ejected from the nozzle (not shown) of the movable nozzle 705 in different directions. At the same time, by installing a plurality of water dividers 7051 directly above the surface of the movable nozzle 705, part of the water source entering the movable nozzle 705 can also enter the water divider 7051. The upper diverter pipe 7052 and the lower diverter pipe 7053 connected to the top and bottom sides of the water divider 7051 can divert the water from the water divider 7051 to the movable nozzle 7051. The water flow inside the slurry tank 1 is split and sprayed in opposite directions respectively. The water flow sprayed from the upper split pipe 7052 enters the pulping tank 1 in an oblique upward direction for mixing, while the water flow sprayed from the lower split pipe 7053 directly washes the inner wall surface of the funnel area 102 in an oblique downward direction. While playing the role of diverting the water flow, it can also wash the sediment remaining on the surface of the funnel area 102 to float, so as to cooperate with the stirring mechanism 4 to fully mix the water flow and lime material inside the pulping tank 1 and improve the mixing effect.

[0040] It should be noted that, since the rotating shaft 708 is driven by a stepper motor installed at the bottom of the funnel area 102, and the rotating shaft 708 drives the driven gear 707 to rotate by driving the driving gear 709, and the rotation of the driven gear 707 drives the movable nozzle 705 to rotate, in order to prevent the lower diverter pipe 7053 from directly contacting and colliding with the inner wall of the funnel area 102 when the movable nozzle 705 rotates, the stepper motor is set to start reverse rotation when the lower diverter pipe 7053 at the bottom of the water distributor 7051 contacts the inner wall of the funnel area 102 after rotation, so that the stepper motor switches between forward and reverse rotation, while realizing the continuous rotation of the movable nozzle 705, preventing the lower diverter pipe 7053 from directly contacting and colliding with the inner wall of the funnel area 102.

[0041] For example, if the lower shunt pipe 7053 contacts the inner wall of the funnel area 102 after the movable nozzle 705 rotates clockwise or counterclockwise by 30°, the rotation process of the stepper motor is set to rotate clockwise first, start counterclockwise rotation after reaching 30° clockwise, and start clockwise rotation after reaching 60° counterclockwise, and cycle in sequence; or set to start counterclockwise rotation each time, start clockwise rotation after reaching 30° counterclockwise, and start counterclockwise rotation after reaching 60° clockwise, and cycle in sequence. It is ensured that the entire rotation process of the movable nozzle 705 does not cause the lower shunt pipe 7053 to directly collide with the inner wall of the funnel area 102.

[0042] In some other embodiments, the height of the upper diverter pipe 7052 does not exceed the height of the surface of the movable nozzle 705, so as to ensure that the subsequent scraping mechanism 5 will not be blocked by the upper diverter pipe 7052 when scraping materials.

[0043] In some other embodiments, the agitator 403 includes a plurality of stirring blades 4031 installed on the outer wall of the bottom end of the driving shaft 402, the scraping mechanism 5 includes a fan-shaped scraper 501 installed between adjacent stirring blades 4031, the bottom surface of the fan-shaped scraper 501 is parallel to the surface of the funnel area 102, the inner end of the fan-shaped scraper 501 is connected to a second electric push rod 502, the connecting member 6 is installed at the bottom end of the driving shaft 402, and the second electric push rod 502 is fixedly connected to the inside of the connecting member 6. A plurality of scraping strips 504 and a cleaning roller brush 503 are installed at the bottom end of the fan-shaped scraper 501, and the scraping strips 504 and the cleaning roller brush 503 are arranged in sequence at intervals along the radial direction of the fan-shaped scraper 501. The scraping strips 504 and the cleaning roller brush 503 have the same height at the same position, and the bottom surfaces of the scraping strips 504 and the cleaning roller brush 503 are parallel to and in critical contact with the surface of the inclined plane of the funnel, so as to clean the inclined water pipe 701 and the surface of the filling block 710 on the surface of the inclined plane of the funnel, and since the height of the surface of the movable nozzle 705 is lower than the height of the inclined plane of the funnel, it is ensured that the fan-shaped scraper 501 will not affect the movable nozzle 705 when cleaning the inclined plane of the funnel.

[0044] In this embodiment, the scraper mechanism 5 is installed between adjacent stirring blades 4031, and the driving shaft 402 is rotated to drive the stirring blades 4031 to rotate, while driving the fan-shaped scraper 501 located between the adjacent stirring blades 4031 to rotate, and the plurality of scraping strips 504 and the cleaning roller brush 503 at the bottom of the fan-shaped scraper 501 are used to clean the inclined water pipe 701 and the surface of the filling block 710 on the inclined plane surface of the funnel. On the one hand, the stirring effect of the agitator 403 is increased, and on the other hand, the scraping strips 504 and the cleaning roller brush 503 at the bottom can be directly used to clean the inclined water pipe 701 and the surface of the filling block 710 on the inclined plane surface of the funnel, thereby further reducing the residue in the funnel area 102.

[0045] Furthermore, considering that the stirring blade 4031 does not cover the entire interior of the pulping tank 1, the fan-shaped scraper 501 is pushed outward by the second electric push rod 502, thereby adjusting the active area of ​​the entire fan-shaped scraper 501, so that the fan-shaped scraper 501 can cover more areas of the inclined water pipe 701 and the filling block 710 on the inclined plane surface of the funnel when rotating, so as to scrape more areas of the funnel area 102 surface.

[0046] Furthermore, a storage chamber 5011 is provided inside the fan-shaped scraper 501, and a vibrator 5012 is installed inside the storage chamber 5011. The vibrator 5012 is connected to the scraper bar 504 and the cleaning roller brush 503 to remove the sediments adhering to the surface of the scraper bar 504 by vibration. In order to further improve the removal effect of the fan-shaped scraper 501 on the residue on the surface of the funnel inclined plane, the vibrator 5012 is installed in the storage chamber 5011 in the fan-shaped scraper 501, so that when the fan-shaped scraper 501 cleans the surface of the funnel area 102, the sediments remaining on the surface of the funnel area 102 are accelerated to fall off by vibration, thereby improving the scraping effect. And after the active area of ​​the fan-shaped scraper 501 is adjusted in cooperation with the second electric push rod 502, the cleaning effect of the fan-shaped scraper 501 on the surface of the funnel inclined plane is further improved.

[0047] In some other embodiments, a plurality of first rigid strips 5031 are evenly arranged along the axial direction on the bottom surface of the cleaning roller brush 503, and a plurality of second rigid strips 5032 are evenly arranged along the circumference of the outer wall on the bottom surface of the cleaning roller brush 503, the bottom height of the first rigid strip 5031 and the bottom height of the second rigid strip 5032 are both the same as the bottom height of the scraper strip 504 at the same position, a scraping area 5033 is formed between adjacent first rigid strips 5031 and second rigid strips 5032, a plurality of flexible crushing columns 5034 are installed inside the scraping area 5033, and the flexible crushing columns 5034 are filled inside the scraping area 5033, a first curved surface is formed on the surface between the plurality of first rigid strips 5031 and the plurality of second rigid strips 5032, a second curved surface is formed between the plurality of flexible crushing columns 5034, and the height of the first curved surface is lower than the height of the second curved surface at the same position.

[0048] In this embodiment, when the fan-shaped scraper 501 rotates to clean the surface of the funnel area 102, the scraping bar 504 and the cleaning roller brush 503 at the bottom are used to scrape the material to remove the sediment remaining on the inclined plane surface of the funnel, including the sediment remaining on the surface of the inclined water pipe 701 and the filling block 710. Specifically, during the rotation of the fan-shaped scraper 501, a plurality of first rigid bars 5031 and second rigid bars 5032 are evenly arranged on the bottom surface of the cleaning roller brush 503, and a scraping area 5033 is formed between the adjacent first rigid bars 5031 and second rigid bars 5032, and a plurality of flexible crushing columns 5034 are installed inside the scraping area 5033, so that when the cleaning roller brush 503 scrapes the sediment on the surface of the funnel area 102, the residue on the surface of the funnel area 102 is scraped off by the first rigid bars 5031 and the second rigid bars 5032, and after the residue is scraped off, a plurality of flexible crushing columns 5034 are installed inside the scraping area 5033 to further crush the scraped residue, so that the residue is further mixed inside the pulping tank 1, thereby reducing the generation and deposition of sediment.

[0049] Moreover, the surfaces between the multiple first rigid bars 5031 and the multiple second rigid bars 5032 form a first curved surface, and the surfaces between the multiple flexible crushing columns 5034 form a second curved surface. Since the bottom height of the first rigid bar 5031 and the bottom height of the second rigid bar 5032 are the same as the bottom height of the scraping bar 504 at the same position, and the height of the first curved surface is lower than the height of the second curved surface at the same position, the first rigid bar 5031, the second rigid bar 5032 and the scraping bar 504 can preferentially contact the sediment on the inclined plane surface of the funnel to improve the scraping effect of the sediment, so as to cooperate with the flexible crushing column 5034 to perform secondary crushing on the scraped sediment, and at the same time, it also avoids direct contact between the flexible crushing column 5034 and the sediment to reduce wear.

[0050] In summary, the semi-dry lime slurry preparation device for garbage disposal of the present invention discharges water into the pulping tank from different positions by arranging a water inlet mechanism, and after the lime material is fed into the pulping tank by the feeding mechanism, the lime material is evenly stirred by the stirring mechanism, and during the stirring process, the deposited lime material remaining at the bottom of the pulping tank is scraped up and stirred for a second time by a scraping mechanism connected to the stirring mechanism, thereby effectively preventing the bottom from settling, and the remaining sediment is cleaned by a cleaning mechanism installed at the bottom end of the pulping tank, further eliminating the sediment at the bottom of the pulping tank, and effectively preventing the subsequent clogging of the pulping tank and affecting the efficiency of lime slurry preparation; therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.
