Description

Technical Field

[0001] The invention relates to the technical field of garbage incineration treatment, and in particular to a garbage feeder of a garbage incineration boiler. Background Art

[0002] Garbage incineration is the most widely used method of garbage disposal. Garbage incineration is to put garbage into an incinerator for combustion, release heat energy, preheat it for recycling, and then provide heat or generate electricity. It has great advantages over other garbage disposal methods.

[0003] A garbage incinerator is a device for incinerating and treating garbage. The garbage burns in the furnace and turns into waste gas which enters the secondary combustion chamber. It is completely burned under the forced combustion of the burner and then enters the spray dust collector. After dust removal, it is discharged into the atmosphere through the chimney. A garbage incinerator generally consists of four major systems: garbage pre-treatment system, incineration system, smoke biochemical dust removal system and gas generator (auxiliary ignition and incineration).

[0004] A garbage incinerator feeding device is disclosed in the patent document with application number CN202023039050.0, which includes a storage hopper, a displacement mechanism for driving the storage hopper to move toward the incinerator is arranged below the storage hopper, and a cleaning mechanism for driving the storage hopper to flip vertically is arranged on the displacement mechanism. During operation, the operator fills the garbage into the storage hopper at the end of the track away from the incinerator, and then controls the drive motor to drive the installation box to move on the track; when the storage hopper moves to the specified dumping position, the second hydraulic cylinder is controlled, and the second hydraulic cylinder is extended to drive the storage hopper to flip, and the garbage in the storage hopper immediately enters the incinerator. If the garbage in the storage hopper is not completely dumped, the operator can control the cylinder, and the cylinder drives the scraper to move, and then push the remaining garbage in the storage hopper into the incinerator. The feeding device of the garbage incinerator relies on the reciprocating motion of the storage hopper to put the garbage into the garbage incinerator. When the storage hopper is far away from the incinerator, the work done is useless, and the feeding device cannot continuously feed the garbage incinerator.

[0005] Some waste incinerator feeding devices rely on conveyor belts to feed the incinerator. Although they can feed the waste incinerator uninterruptedly, the dirt on the garbage is easy to adhere to the conveyor belt. When the conveyor belt part with dirt moves to the bottom, the dirt on the conveyor belt is easy to fall off. For this reason, it is necessary to set a dirt cleaning component for the conveyor belt.

[0006] In conventional technology, the suction force of the exhaust fan is used to collect dirt from the conveyor belt below. The suction force of the exhaust fan is generally constant. However, because some areas of the conveyor belt surface have more dirt and some areas have less dust, the areas with more dirt require a larger suction force, while the areas with less dirt only require a smaller suction force or even no suction force. Therefore, when the conveyor belt is suctioned and cleaned, if the exhaust fan maintains a larger suction force throughout the process, the area with less dirt on the conveyor belt will pass through the exhaust fan, and the exhaust fan will maintain a larger suction force, which is considered a waste of energy. If the exhaust fan maintains a smaller suction force throughout the process, the area with more dirt on the conveyor belt will have a poor cleaning effect when passing through the exhaust fan.

[0007] Similarly, in conventional technology, when using a scraper to scrape dirt off a conveyor belt, the extrusion force of the scraper on the conveyor belt is generally constant. The greater the extrusion force, the better the scraping effect. However, the greater the extrusion force of the scraper on the conveyor belt, the greater the friction during the movement of the conveyor belt, which in turn causes the motor driving the conveyor belt to consume more energy. However, since some areas of the conveyor belt have more dirt and some areas have less dirt, the areas with more dirt certainly require a greater extrusion force between the scraper and the conveyor belt, while the areas with less dirt do not require a greater extrusion force between the scraper and the conveyor belt. When using a scraper to scrape and clean the conveyor belt, if the scraper and the conveyor belt are kept in a state of greater extrusion force throughout the entire process, when the area with less dirt on the conveyor belt passes through the scraper, the greater extrusion force of the scraper on the conveyor belt will increase the energy consumption of the motor driving the conveyor belt. In addition, if the scraper and the conveyor belt maintain high friction for a long time, the service life of the conveyor belt will be reduced. Summary of the invention

[0040] Embodiment 1: Figure 1-Figure 15 As shown, a garbage feeder for a garbage incineration boiler comprises a housing 1, an inlet 2 is provided at the upper end of the housing 1, and an outlet is provided at one end in the length direction of the housing 1. A conveyor belt 3 is installed in the housing 1, and one end of the conveyor belt 3 passes through the outlet.

[0041] The inner side and the outer side of the shell 1 are both rotatably connected with transmission rollers 4, and the two transmission rollers 4 are connected through the conveyor belt 3. Any one of the transmission rollers 4 is driven by a motor. Two upper and lower fixed plates 6 are fixed in the shell 1. The upper end of the upper fixed plate 6 is in sliding contact with the lower end of the straight portion on the upper side of the conveyor belt 3, and the lower end of the lower fixed plate 6 is in sliding contact with the upper end of the straight portion on the lower side of the conveyor belt 3.

[0042] like Figure 2 As shown, after the garbage is put into the inlet 2 of the shell 1, the garbage falls onto the conveyor belt 3. After the conveyor belt 3 is started, the garbage on the conveyor belt 3 is conveyed to the right side, and the garbage falls from the right end of the conveyor belt 3 and enters the garbage incinerator.

[0043] like Figure 3 and Figure 5 As shown, a plurality of iron bars 5 are embedded and fixed in the conveyor belt 3, and the plurality of iron bars 5 are evenly arranged along the moving track of the conveyor belt 3. The portion of the conveyor belt 3 between two adjacent iron bars 5 is the area to be processed, and the plurality of iron bars 5 divide the conveyor belt 3 into a plurality of areas to be processed. The outer edge of the conveyor belt 3 between two adjacent iron bars 5 is the surface to be cleaned.

[0044] The conveyor belt 3 is fixed with isolation belts 7 at both ends along the width direction of the housing 1. The isolation belts 7 can prevent the garbage from falling from the conveyor belt 3 when the conveyor belt 3 is conveying the garbage.

[0045] A suction assembly is arranged in the housing 1 below the conveyor belt 3. The suction assembly includes a collection assembly, and an air suction hood 13 is elastically slidably connected above the collection assembly. The air suction hood 13 is connected to the collection assembly through a bellows 14 and an exhaust fan 15. The upper end of the air suction hood 13 is open, and the air suction hood 13 can slide in the height direction of the housing 1. When the exhaust fan 15 is started, the air in the housing 1 enters the box 16 through the opening at the upper end of the air suction hood 13, the air suction hood 13, the bellows 14 and the exhaust fan 15 in sequence.

[0046] like Figure 6 and Fig. 9 As shown, the collecting assembly includes a box body 16 fixed in the housing 1, a through hole is provided on one side of the box body 16, a filter screen 32 is fixed in the through hole, a storage box 17 is slidably inserted on the other side of the box body 16, the inside of the box body 16 is connected with the outlet end of the exhaust fan 15, the inlet end of the exhaust fan 15 is connected with one end of the bellows 14, and the other end of the bellows 14 is fixedly connected with the lower end of the suction hood 13. When the air in the housing 1 passes through the opening at the upper end of the suction hood 13, it can carry the dirt on the lower end surface of the conveyor belt 3 and enter the box body 16 through the suction hood 13, the bellows 14 and the exhaust fan 15 in sequence. The dirt is intercepted by the filter screen 32 and falls into the storage box 17, and the air in the box body 16 is discharged through the filter screen 32. After the storage box 17 is pulled out from the box body 16, the dirt in the storage box 17 can be cleaned.

[0047] like Figure 2 , Figure 6 and Fig. 9 As shown, a plurality of vertical fixing rods 18 are fixed to the upper end of the box body 16, and the fixing rods 18 are slidably connected to the air suction hood 13. A second spring 19 is sleeved on the fixing rods 18, and one end of the second spring 19 is fixedly connected to the air suction hood 13, and the other end of the second spring 19 is fixedly connected to the box body 16.

[0048] like Figure 6 and Fig. 9 As shown, electromagnets 20 are embedded and fixed at both ends of the air suction cover 13 along the width direction of the shell 1.

[0049] like Fig. 9 As shown, a scraper 21 and a magnetic sensor 33 are respectively provided on both ends of the suction hood 13 along the length direction of the shell 1 , and the magnetic sensor 33 is closer to the outlet of the shell 1 relative to the scraper 21 .

[0050] like Figure 8 As shown, the scraper 21 is elastically slidably connected with the suction hood 13. Specifically, the scraper 21 can slide in the height direction of the housing 1, and a vertical slide groove 22 is provided at the upper end of the suction hood 13. The lower end of the scraper 21 is slidably arranged in the slide groove 22, and the lower end of the scraper 21 is connected to the bottom of the slide groove 22 through a third spring 25. The upper end of the scraper 21 contacts the lower end surface of the lower straight portion of the conveyor belt 3 between the two isolation belts 7.

[0051] A conductive slider 24 is fixed on the scraper 21 , and a resistor bar 23 is fixed on the air suction cover 13 . The conductive slider 24 and the resistor bar 23 are electrically slidably connected.

[0052] like Fig. 9 and Fig.10 As shown, a camera module 12 is fixed in the housing 1 , and the camera module 12 can capture an image of the lower end surface of the conveyor belt 3 above the suction hood 13 .

[0053] The magnetic sensor 33 and the camera module 12 are electrically connected to the controller via the image recognition module. The power supply, the current detection module, the resistor bar 23 and the conductive slider 24 form a series circuit. The current detection module, the controller, the exhaust fan 15 and the electromagnet 20 are electrically connected.

[0054] like Fig.10 As shown, the width a of the inner cavity of the air hood 13 is greater than the distance between two adjacent iron bars 5 on the straight portion of the conveyor belt 3, the width a of the inner cavity of the air hood 13 and the distance between two adjacent iron bars 5 on the straight portion of the conveyor belt 3 differ by the length of one iron bar 5, the length of the electromagnet 20 is equal to the width a of the inner cavity of the air hood 13, and the contact line between the upper end of the scraper 21 and the conveyor belt 3 is flush with the inner wall of the air hood 13 which is perpendicular to the length direction of the shell 1 and far away from the outlet of the shell 1. When the two adjacent iron bars 5 on the lower straight portion of the conveyor belt 3 are located above the air hood 13, the magnetic sensor 33 senses one of the iron bars 5 above the air hood 13 and sends a signal to the controller. After receiving the signal from the magnetic sensor 33, the controller starts the camera module 12, and the camera module 12 can take a picture of the lower end surface of the lower straight portion of the conveyor belt 3 above the air hood 13.

[0055] like Fig.10As shown, after the conveyor belt 3 is started, the electromagnet 20 and the exhaust fan 15 are started, and the electromagnet 20 can absorb the iron bar 5 in the straight portion on the lower side of the conveyor belt 3, so that the straight portion on the lower side of the conveyor belt 3 is close to the upper end of the scraper 21.

[0056] like Fig.10 As shown, the straight portion of the lower side of the conveyor belt 3 moves to the left. After any two adjacent iron bars 5 on the straight portion of the lower side of the conveyor belt 3 are located above the suction hood 13, when the right end of the iron bar 5 on the left is flush with the contact line between the upper end of the scraper 21 and the conveyor belt 3, the right end of the iron bar 5 on the right is flush with the right inner wall of the suction hood 13. At this time, the magnetic sensor 33 senses the iron bar 5 on the right and sends a signal to the controller, and the controller starts the camera module 12. The camera module 12 takes a picture of the surface to be cleaned directly above the suction hood 13 (the outer edge of the conveyor belt 3 between the two adjacent iron bars 5 is the surface to be cleaned). The camera module 12 transmits the image information of the surface to be cleaned directly above the suction hood 13 to the image recognition module for recognition, and then determines the amount of dirt on the surface to be cleaned directly above the suction hood 13.

[0057] When the result of the image recognition module recognition is that the amount of dirt on the surface to be cleaned directly above the suction hood 13 is large, the controller starts the electromagnet 20 and increases the magnetic attraction of the electromagnet 20. After the magnetic force of the electromagnet 20 increases, the magnetic attraction of the electromagnet 20 to the iron bars 5 in the area to be processed directly above the suction hood 13 (the part of the conveyor belt 3 between two adjacent iron bars 5 is the area to be processed, and the plurality of iron bars 5 divide the conveyor belt 3 into a plurality of areas to be processed) increases. The area to be processed directly above the suction hood 13 can move downward and squeeze the scraper 21. After the scraper 21 is squeezed by the area to be processed directly above the suction hood 13, the squeezing force between the scraper 21 and the conveyor belt 3 increases. After the squeezing force between the scraper 21 and the area to be processed directly above the suction hood 13 increases, as the conveyor belt 3 moves, the scraper 21 can ensure that the dirt on the surface to be cleaned directly above the suction hood 13 is effectively scraped off.

[0058] After the squeezing force between the scraper 21 and the area to be treated just above the suction hood 13 increases, the scraper 21 moves downward in the slide 22 and squeezes the third spring 25. At the same time, the conductive slider 24 slides relative to the resistor bar 23, and the current in the series circuit formed by the power supply, the current detection module, the resistor bar 23 and the conductive slider 24 increases. Then the current detection module box controller sends a signal, and the controller increases the power of the exhaust fan 15. That is, when the squeezing force between the area to be treated just above the suction hood 13 and the scraper 21 increases, the power of the exhaust fan 15 increases, which can improve the cleaning effect of the dirt on the surface to be cleaned just above the suction hood 13. After the area to be treated just above the suction hood 13 squeezes the scraper 21, the area to be treated just above the suction hood 13 is close to the upper port of the suction hood 13, which can further improve the processing efficiency of the dirt on the surface to be cleaned just above the suction hood 13.

[0059] As the conveyor belt 3 continues to move, the surface to be cleaned passes over the suction hood 13 in turn. The camera module 12 and the image recognition module analyze the amount of dirt on the surface to be cleaned in turn. At the same time, the magnetic attraction of the electromagnet 20 and the power of the exhaust fan 15 are adjusted according to the amount of dirt on the surface to be cleaned directly above the suction hood 13. This ensures that the dirt on the surface to be cleaned is effectively scraped off and energy consumption can be saved.

[0060] Since the width a of the inner cavity of the suction hood 13 is greater than the distance between two adjacent iron bars 5 on the straight part of the conveyor belt 3, the width a of the inner cavity of the suction hood 13 and the distance between two adjacent iron bars 5 on the straight part of the conveyor belt 3 differ by the length of one iron bar 5. The length of the electromagnet 20 is equal to the width a of the inner cavity of the suction hood 13. The contact line between the upper end of the scraper 21 and the conveyor belt 3 is flush with the inner wall of the suction hood 13 which is perpendicular to the length direction of the shell 1 and far away from the outlet of the shell 1. Therefore, when the controller receives the information sent by the image recognition module and adjusts the magnetic attraction of the electromagnet 20 and the power of the exhaust fan 15, the scraper 21 scrapes the dirt on the surface to be cleaned above the suction hood 13, and the camera module 12 does not take pictures, and the magnetic attraction of the electromagnet 20 remains unchanged, that is, the extrusion force between the scraper 21 and the area to be processed directly above the suction hood 13 remains unchanged. The power of the exhaust fan 15 also remains unchanged. When the surface to be cleaned directly above the suction hood 13 passes the upper end of the scraper 21 as a whole, the magnetic sensor 33 will sense the subsequent iron bar 5, and the camera module 12 will work. In this embodiment, not only can the amount of dirt on multiple surfaces to be cleaned be analyzed in sequence, but also in the process of the scraper 21 scraping the dirt on one surface to be cleaned, the squeezing force between the scraper 21 and the area to be processed directly above the suction hood 13 can be ensured to remain unchanged, and the power of the exhaust fan 15 can remain unchanged, so as to ensure the scraping effect of the dirt on the surface to be cleaned.

[0061] When the image recognition module identifies that the amount of dirt on the surface to be cleaned directly above the suction hood 13 is small, the power of the exhaust fan 15 remains unchanged, and the magnetic attraction of the electromagnet 20 remains unchanged.

[0062] Embodiment 2: Based on Embodiment 1, Figure 2 and Figure 5 As shown, a cleaning component and a scraping component are arranged in the shell 1 below the conveyor belt 3, and the suction component is located between the cleaning component and the scraping component. The cleaning component is farther away from the outlet of the shell 1 than the scraping component.

[0063] like Figure 2 , Figure 5 and Figure 6As shown, the scraping assembly includes a collecting box 8 fixed in the shell 1, and an inclined sliding cavity 9 is opened at the upper end of one side of the collecting box 8 away from the outlet of the shell 1 in the length direction of the shell 1. A scraping plate 10 is slidably arranged in the sliding cavity 9, and the upper end of the scraping plate 10 contacts the lower end surface of the lower straight portion of the conveyor belt 3 between the two isolation belts 7. A first spring 11 is arranged in the sliding cavity 9, and one end of the first spring 11 is fixedly connected to the scraping plate 10, and the other end of the first spring 11 is fixedly connected to the collecting box 8.

[0064] When the straight portion at the lower side of the conveyor belt 3 moves to the left, the shovel plate 10 can remove the garbage attached to the lower end of the lower straight portion of the conveyor belt 3, and the removed garbage enters the collection box 8.

[0065] like Figure 2 , Figure 5 and Fig.11 As shown, the cleaning assembly includes a lifting plate 29, and a cleaning sponge 30 is fixed on the upper end of the lifting plate 29. The upper end of the cleaning sponge 30 contacts the lower end surface of the lower straight portion of the conveyor belt 3 between the two isolation belts 7. Two connecting plates 26 are fixed in the shell 1 below the conveyor belt 3 along the length direction of the shell 1. The connecting plates 26 are vertically arranged. The lifting plate 29 and the cleaning sponge 30 are located between the two connecting plates 26. A plurality of vertical spring telescopic rods 28 are arranged below the lifting plate 29. The upper end of the spring telescopic rod 28 is fixedly connected to the lifting plate 29, and the lower end of the spring telescopic rod 28 is fixedly connected to the bottom plate of the shell 1.
