Description

Technical Field

[0001] The invention relates to the technical field related to garbage incineration power generation equipment, and in particular to a waste residue cleaning device for garbage incineration power generation. Background Art

[0002] Domestic waste incineration power generation is an efficient way to convert domestic waste into electricity. After the waste is collected at the incineration plant, it is first fermented to reduce moisture and increase calorific value, and then pre-treated to remove non-combustibles (such as metal, glass, etc.), and large pieces of waste are broken up for incineration.

[0003] The pre-treated garbage is sent to the incinerator by a grab bucket and burned at a high temperature of more than 850°C. The heat generated is used to generate electricity. The high-temperature flue gas generated during the incineration process heats water through the waste heat boiler to generate steam to drive the steam turbine to generate electricity, and the electricity is finally connected to the power grid. The flue gas generated by incineration needs to go through multiple treatment processes such as deacidification, dust removal, and denitrification to ensure that the emission meets environmental protection standards. The slag after incineration can be used as building materials after treatment, while the fly ash needs to be solidified before safe landfill.

[0004] Specifically for the slag discharge operation, the incinerated slag falls into the ash hopper from the grate gap or the bottom of the furnace bed, and then the slag discharge device such as a screw conveyor, a vibrating conveyor or a chain conveyor directly transports the high-temperature slag to a closed container. A small amount of water spraying may be used to cool the process.

[0005] The existing slag conveyor chain conveyor has certain defects: when the slag viscosity is high under certain high temperature conditions, it is easy to form adhesion on the chain plate, resulting in poor conveying or equipment failure. For this reason, the industry proposes to design the chain plate of the chain conveyor as follows: Figure 1 The tooth shape shown is used to reduce the contact area between the high-temperature slag and the chain plate, thereby avoiding the adhesion of the slag. However, the applicant has found that the toothed chain plate can reduce the adhesion of the slag to a certain extent, but the adhesion still exists, which still leads to poor transportation. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a waste residue cleaning device for waste incineration power generation.

[0007] Specifically, the waste residue cleaning device for garbage incineration power generation disclosed in the present invention focuses on removing the problem of waste residue adhering to the conveyor belt in the later stage of incineration power generation, especially for cleaning the chain conveyor with teeth.

[0008] The present invention is different from the conventional solution in that: it comprises a first tooth and a second tooth arranged in parallel, the first tooth and the second tooth can be meshed in the same tooth groove arranged on a conveyor belt, the conveyor belt is used to output waste slag, and the conveyor belt here particularly refers to a chain conveyor with teeth;

[0009] The first tooth can be disengaged from the tooth groove and meshed with the next tooth groove under the interference of the tooth groove on the conveyor belt and the restoring deformation of the elastic member. During this operation, the first tooth always fits the tooth groove under the restoring deformation of the elastic member, and the conveyor belt moves relative to the first tooth. Therefore, the first tooth can form a "scraping" action on the teeth on the conveyor belt in continuous operation, achieving a type of cleaning effect.

[0010] In addition, the second teeth can reciprocate under the action of external force, so that during the transmission of the conveyor belt, the second teeth can disengage from the tooth groove and engage with the next tooth groove. During this operation, the second teeth can clean the sticky waste residue in the tooth groove on the conveyor belt, achieving another type of cleaning effect.

[0011] In some examples of the present invention, a plurality of first teeth and a plurality of second teeth are arranged in parallel to form strip-shaped teeth, corresponding to the strip-shaped tooth grooves on the conveyor belt, and a plurality of first teeth and a plurality of second teeth are arranged at intervals, so that adjacent first teeth and second teeth form a shear force during operation;

[0012] The purpose of such arrangement is to enable the first tooth and the second tooth to clean the conveyor belt at the same time. Specifically, when the first tooth is interfered to the point where it begins to separate from the tooth groove of the conveyor belt, the second tooth is controlled to also separate from the tooth groove of the conveyor belt until the conveyor belt moves horizontally to the point where the two teeth correspond to the new tooth groove.

[0013] The effects that can be achieved in this way are: first, the conveyor belt is cleaned simultaneously by two cleaning methods, which is more effective than a single cleaning method; second, due to the different operating drive modes of the first teeth and the second teeth, the movement rhythms of the two are different, so a shear force can be formed between the first teeth and the second teeth that are set at intervals, and the shear force has a better crushing and cleaning effect on the coked waste slag.

[0014] In some examples of the present invention, the waste residue cleaning device further includes a housing and a first component disposed on the housing, one end of the first component is hinged relative to the housing, an elastic component is disposed between the other end and the housing, and the first tooth is disposed on one end of the first component close to the elastic component and located on a side of the first component away from the elastic component;

[0015] The purpose of such a setting is as follows: The first tooth is arranged on the first component with a relatively larger volume, and the operation of the first tooth is transmitted through the first component, increasing the stability of the operation of the first tooth. At the same time, the contact area between the first tooth and the elastic member is increased. In addition, the relative movement range of the first tooth is limited by the hinged manner.

[0016] In some examples of the present invention, a connecting rod is hinged to one end of each first component close to the elastic member. A guiding cylinder is fixedly arranged in the housing. One end of the connecting rod away from the first component extends into the guiding cylinder, and the elastic member is abutted between this end and the guiding cylinder.

[0017] The purpose of such a setting is as follows: The connecting rod and the guiding cylinder can guide and limit the deformation operation of the elastic member and the operation of the first component, ensuring that the first component moves within the required range, and at the same time increasing the reliability of the movement of the first component.

[0018] In some examples of the present invention, the housing includes a plurality of first housings corresponding to a plurality of first teeth one by one. There are a plurality of corresponding first components, connecting rods, and guiding cylinders. Each guiding cylinder is fixedly arranged in the corresponding first housing.

[0019] In some examples of the present invention, the waste residue cleaning device further includes a second component arranged on the housing. The second component is slidably connected to the housing. The second tooth is arranged at one end of the second component away from the housing.

[0020] The purpose of such a setting is as follows: The second tooth is arranged on the second component with a relatively larger volume, and the operation of the second tooth is transmitted through the second component, increasing the stability of the operation of the second tooth.

[0021] In some examples of the present invention, a hydraulic cylinder is arranged in the housing. One end of the second component away from the second tooth extends into the cylinder body of the hydraulic cylinder and is connected to the piston rod in the cylinder body.

[0022] The purpose of such a setting is as follows: The hydraulic cylinder is used to drive the second tooth on the second component to perform a linear reciprocating motion. One end of the second component extends into the cylinder body of the hydraulic cylinder to use the cylinder body to guide the movement of the second component.

[0023] In some examples of the present invention, both ends of the piston rod are sealed with the side wall of the cylinder body. One end of the piston rod is connected to the second component, and a first chamber is formed between the side part and the cylinder body. The other end forms a second chamber with the cylinder body. Both the first chamber and the second chamber are connected with liquid inlet and outlet ports.

[0024] The purpose of such a setting is as follows: When the first chamber is filled with liquid, the piston rod moves downward. When the second chamber is filled with liquid, the piston rod moves upward. The reciprocating motion of the second component is realized through the transmission of the piston rod.

[0025] In some examples of the present invention, the outer shell includes a number of second outer shells corresponding one by one to a number of second teeth. There are a number of corresponding second components and hydraulic cylinders. Each hydraulic cylinder is fixed within a corresponding second outer shell. The first chambers of two-by-two hydraulic cylinders are connected through a first pipeline, and the second chambers of two-by-two hydraulic cylinders are connected through a second pipeline;

[0026] The purpose of such an arrangement is as follows: By connecting the hydraulic cylinders corresponding to each second tooth through the first pipeline and the second pipeline, it is possible to achieve the synchronous movement of the second teeth as much as possible, and avoid the asynchronous operation between the several second teeth caused by the inconsistent operation between the liquid inlet and outlet ports.

[0027] In some examples of the present invention, the second component and the outer shell are also slidably connected through a kidney-shaped through hole provided on both of them and a pin body passing through the kidney-shaped through hole;

[0028] The purpose of such an arrangement is as follows: To further assist the reciprocating movement of the second component and avoid the unstable movement of the second component.

[0029] Additional aspects and advantages of the present invention will be given in part in the following description, will become apparent in part from the following description, or will be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0042] Refer to the following Figures 2 to 5 shown to describe a slag cleaning device for waste incineration power generation provided by an embodiment of the present invention, which is specifically illustrated by the chain plate machine with teeth mentioned in the background art.

[0043] Please refer to the attached Figure 2 , which is a perspective view of the slag cleaning device for waste incineration power generation. The slag cleaning device includes a plurality of first teeth 1 and a plurality of second teeth 2 arranged in parallel. The first teeth 1 and the second teeth 2 can be engaged in the same tooth groove provided on the chain plate machine. Specifically, a plurality of chain plates provided on the chain plate machine form an annular structure, so that a certain chain plate undergoes displacement along the annular shape during operation. When the chain plate is displaced to a certain position below the annular structure, the tooth groove on the chain plate can form an engagement with the first teeth 1 and the second teeth 2;

[0044] Among them, the first teeth 1 are arranged to perform the operation of disengaging from the tooth groove and engaging with the next tooth groove under the interference action of the tooth groove on the chain plate machine and the restoring deformation action of the elastic member 3. The elastic member 3 is a cylindrical spring;

[0045] The source of the interference action of the chain plate machine is as follows: during the operation of the chain plate, the displacement direction thereof is substantially perpendicular to the extension direction of the first teeth 1. When the chain plate corresponds to the slag cleaning device during displacement, it can interfere with the first teeth 1, causing the first teeth 1 to disengage from the engaged tooth groove. During this process, the first teeth 1 are always in contact with the teeth on the chain plate, and interference occurs between the two, so that the adhered furnace slag can be cleaned;

[0046] Among them, the second teeth 2 can perform reciprocating motion under an external force, so that during the transportation of the chain plate machine, the second teeth 2 perform the operation of disengaging from the tooth groove and engaging with the next tooth groove;

[0047] That is, during the operation of the chain plate, the extension direction of the second tooth 2 is basically perpendicular to the chain plate machine. By controlling the second tooth 2 to produce reciprocating motion toward and away from the chain plate machine, the second tooth 2 can disengage from the tooth groove and engage with the next tooth groove during the transportation of the chain plate machine, thereby cleaning the slag stuck in the tooth groove of the chain plate machine.

[0049] Specifically, since the first tooth 1 undergoes angular displacement and the second tooth 2 undergoes linear reciprocating displacement, the movement rhythms of the two are different, so that shearing force can be generated by arranging the two adjacent to each other.
