Description

Technical Field

[0001] The utility model relates to the technical field of sorting equipment, in particular to a jigger and a garbage slag processing system. Background Art

[0002] A large amount of slag is generated in the process of waste incineration power generation. The components of slag are complex, including coal ash, scrap iron, heavy metals, etc. It needs to be processed by the slag treatment system before it can be landfilled or made into bricks. The structure of the existing slag treatment system usually includes screening mechanism, crushing mechanism, jig, dehydration mechanism, conveying mechanism and other devices. Among them, the role of the jig is to screen the crushed slag in layers, remove and recover the metal medium contained in it.

[0003] At present, there are many types of jigs, including side-moving, top-moving and bottom-moving types. Among them, the jig uses water as the sorting medium, and the slag is layered according to its specific gravity through the agitation of water, and the upper layer of materials is washed away by the flow of water, thereby achieving the purpose of sorting. However, when the jig is running, the materials in the lower layer will accumulate. When the accumulation reaches a certain amount, it needs to be stopped to remove them, which is extremely inconvenient to operate and will also affect the working efficiency of the slag treatment system. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a jigger, which has strong working continuity and can easily remove the materials in the lower layer without stopping the machine, which helps to improve the working efficiency of the garbage slag treatment system, and has a simple structure, low manufacturing cost and low operating energy consumption.

[0005] In addition, the utility model also provides a garbage slag treatment system having the jig machine.

[0006] The first embodiment of the utility model provides a jigger, which comprises:

[0007] A shell having a cavity, and a feed port, a first outlet, and a second outlet all connected to the cavity, wherein the first outlet and the second outlet are both located on a peripheral wall of the shell;

[0008] A partition plate extending vertically and arranged at the upper part of the cavity, wherein the front and rear ends of the partition plate are respectively connected to the wall surface of the cavity, and the partition plate is provided with a first through hole and a second through hole spaced apart from each other vertically;

[0009] A first sieve plate is disposed on the left side of the partition, the first sieve plate is located below the feed port and is connected to the wall of the cavity and the partition respectively, the first sieve plate is inclined downward from left to right and extends to the lower end of the second through hole;

[0010] a second sieve plate, arranged on the right side of the partition plate, the second sieve plate tilts downward from left to right and is respectively connected to the wall of the cavity and the partition plate, the upper end of the second sieve plate extends to the lower end of the first through hole, and the lower end of the second sieve plate extends to the lower end of the first outlet;

[0011] A discharge plate is arranged on the right side of the partition and is connected to the wall of the cavity and the partition respectively. The discharge plate, the first sieve plate and the second sieve plate are arranged from bottom to top. The discharge plate is provided with a water outlet. A one-way valve with a flow direction from top to bottom is provided in the water outlet. The right end of the discharge plate extends to the lower end of the second outlet.

[0015] The jigger according to the embodiment of the first aspect of the utility model has at least the following beneficial effects: during the operation of the jigger, the garbage slag enters the cavity of the shell from the feed port and falls on the first screen plate, the pulsating device operates and generates a pulsating water flow, and under the action of the pulsating water flow, the garbage slag will be stratified according to specific gravity, and the slag component located in the upper layer will flow to the second screen plate through the first through hole with the water, and then, at least a part of the water will flow downward through the second screen plate due to gravity, and can flow back from the one-way valve of the discharge plate, and the slag component will move out of the first outlet along the second screen plate due to gravity; because the first screen plate is arranged at an angle, and the upper end of the sealing plate is hinged to the partition, and the second through hole is blocked under the action of the reset component. Therefore, as the working time increases, the slag components of the lower layer accumulate more on the first screen plate. When the slag components of the lower layer accumulate to a certain amount, this part of the slag components can overcome the effect of the reset assembly under the action of its own gravity, so that the sealing plate swings by itself and opens the second through hole, so that the slag components of the lower layer can fall down to the discharge plate through the second through hole due to the action of gravity, thereby reducing the accumulation of the lower side slag components on the first screen plate, so as to allow more garbage slag to enter the shell through the feed port; at the same time, it is convenient to take away the slag components of the lower layer from the second outlet, and the lower slag components on the first screen plate can be easily taken out without stopping the machine, thereby improving the working continuity of the jigger and helping to improve the working efficiency of the garbage slag treatment system.

[0016] Moreover, the reset component is a torsion spring or a compression spring, which does not require power supply, can avoid water-electricity contact accidents, and can reduce the manufacturing cost and operating energy consumption of the jig.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it is to be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the prior art, a large amount of slag is generated during the waste incineration power generation process. The slag has complex components, including coal ash, scrap iron, heavy metals, etc. It needs to be processed by a slag treatment system before it can be landfilled or made into bricks. The existing slag treatment system, such as the slag treatment system disclosed in the invention patent with publication number CN112371691B, generally includes a screening mechanism, a crushing mechanism, a jig, a dehydration mechanism, a conveying mechanism and other devices, wherein the jig is used to screen the crushed slag in layers, remove and recover the metal medium contained therein.

[0037] At present, there are many types of jig products, including side-moving jigs, top-moving jigs and bottom-moving jigs. Among them, the jig uses water as the sorting medium, and the slag is layered according to its specific gravity through the agitation of water, and the kinetic energy of water is used to flush away the upper layer of materials, thereby achieving the purpose of sorting. However, during the operation of the jig, the lower layer of materials will accumulate inside the jig. When the accumulation reaches a certain amount, the staff needs to stop the jig to remove it, which is extremely inconvenient and will also affect the working efficiency of the slag treatment system.

[0038] Based on the above problems, an embodiment of the utility model provides a jig and a garbage slag treatment system, wherein the jig has the advantages of simple structure, low manufacturing cost, low operating energy consumption and strong working continuity. The material in the lower layer can be easily removed without stopping, which helps to improve the working efficiency of the garbage slag treatment system.

[0039] Reference below Figures 1 to 4 The present invention describes a jigger and a garbage slag treatment system according to an embodiment of the present invention.

[0040] like Figure 1 As shown, the jigger according to the first embodiment of the first aspect of the utility model includes a housing 100, a partition plate 330, a first screen plate 310, a second screen plate 320, a discharge plate 340, a sealing plate 410, a reset assembly and a pulsation device 200. In this embodiment, the Z axis of the jigger points from the lower direction of the housing 100 to the upper direction, and the Y axis of the jigger points from the left direction of the housing 100 to the right direction.

[0041] The shell 100 is hollow inside to form a cavity, and the shell 100 is provided with a feed port, a first outlet 150 and a second outlet 160, wherein the feed port is located at the upper part of the shell 100 and is connected to the cavity. The first outlet 150 and the second outlet 160 are both located on the peripheral wall of the shell 100 and are connected to the cavity.

[0042] In the present embodiment, the opening of the cavity is open upward. The first outlet 150 and the second outlet 160 are arranged relatively to each other in the up and down directions of the shell 100, and the first outlet 150 is located above the second outlet 160. It can be understood that the shape and size of the feed port, the first outlet 150 and the second outlet 160 can be set according to actual conditions. The feed port allows garbage slag to enter the cavity of the shell 100, and further, water can flow in to complete the water replenishment in the cavity. Of course, a water inlet can also be set on the peripheral wall of the shell 100, and a control valve can be set at the water inlet.

[0043] The length direction of the partition 330 extends in the up-down direction. The partition 330 is arranged at the upper part of the cavity. Moreover, the front and rear ends of the partition 330 are respectively connected to the wall surface of the cavity to divide the upper space of the cavity into two. In this embodiment, the partition 330 can be fixed in the cavity of the shell 100 by welding, and the partition 330 is in the shape of a rectangular plate.

[0044] The partition plate 330 is provided with a first through hole 331 and a second through hole 332 , the central axis of the first through hole 331 and the central axis of the second through hole 332 both extend in the left-right direction, the first through hole 331 and the second through hole 332 are spaced apart from each other, and the first through hole 331 is located above the second through hole 332 .

[0045] It is understandable that the height distance between the first through hole 331 and the second through hole 332 can be set according to actual conditions, and is not specifically limited here. The first through hole 331 and the second through hole 332 can be round holes, square holes or special-shaped holes. The first through hole 331 is provided so that the upper slag component in the water can pass through, and the second through hole 332 is provided so that the lower slag component in the water can pass through.

[0046] The first sieve plate 310 is disposed on the left side of the partition plate 330. The first sieve plate 310 is located below the feed port. The first sieve plate 310 is connected to the wall of the cavity and the partition plate 330, respectively. Specifically, the periphery of the first sieve plate 310 is fixedly connected to the wall of the cavity and the partition plate 330, respectively, through a welding process. The first sieve plate 310 is arranged downwardly from left to right, and the lower end of the first sieve plate 310 extends to the lower end of the second through hole 332, so that the lower layer of slag components on the first sieve plate 310 can move along the first sieve plate 310 and pass through the second through hole 332.

[0047] The second sieve plate 320 is arranged on the right side of the partition plate 330, and the second sieve plate 320 is located below the feed port. The second sieve plate 320 is connected to the wall of the cavity and the partition plate 330 respectively. Specifically, the periphery of the second sieve plate 320 is fixedly connected to the wall of the cavity and the partition plate 330 respectively by welding. The second sieve plate 320 is arranged downwardly from left to right, and the upper end of the second sieve plate 320 extends to the lower end of the first through hole 331, and the lower end of the second sieve plate 320 extends to the lower end of the first outlet 150, so that the slag components of the upper layer can move to the second sieve plate 320 through the first through hole 331, and can move along the second sieve plate 320 and pass through the first outlet 150, thereby realizing the discharge of the slag components of the upper layer.

[0048] It is understandable that the first sieve plate 310 and the second sieve plate 320 are respectively provided with water through holes, which penetrate from top to bottom, so that garbage slag cannot pass through the water through holes of the first sieve plate 310 and the water through holes of the second sieve plate 320, and the water through holes of the first sieve plate 310 and the water through holes of the second sieve plate 320 can only supply water to flow. The water through holes can be circular holes, and the inner diameter of the water through holes can be set according to actual conditions, and is not specifically limited here.

[0049] The discharge plate 340 is arranged on the right side of the partition 330, and the discharge plate 340 is connected to the wall surface of the cavity and the partition 330 respectively. Specifically, the periphery of the discharge plate 340 is fixedly connected to the wall surface of the cavity and the partition 330 by welding. The right end of the discharge plate 340 extends to the lower end of the second outlet 160, so the lower layer of slag components on the discharge plate 340 can pass through the second outlet 160 and leave the cavity of the shell 100. The discharge plate 340, the first screen plate 310 and the second screen plate 320 are arranged from bottom to top.

[0050] It is understandable that the height distance between the discharge plate 340 and the first screen plate 310, and the height distance between the discharge plate 340 and the second screen plate 320 can be set according to actual conditions.

[0051] The partition plate 330, the first sieve plate 310, the second sieve plate 320 and the discharge plate 340 are all located in the cavity of the housing 100, and the cavity is divided into four sub-cavities, namely the first sub-cavity 110, the second sub-cavity 120, the third sub-cavity 130 and the fourth sub-cavity 140. Among them, the first sub-cavity 110 is located on the left side of the partition plate 330, the second sub-cavity 120 and the third sub-cavity 130 are located on the right side of the partition plate 330, the third sub-cavity 130 is located below the second sub-cavity 120, and the fourth sub-cavity 140 is located below the first sub-cavity 110, the second sub-cavity 120 and the third sub-cavity 130. The first through hole 331 is connected to the first sub-cavity 110 and the second sub-cavity 120 respectively, and the second through hole 332 is connected to the first sub-cavity 110 and the third sub-cavity 130 respectively. The feed port is communicated with the first sub-chamber 110 , the first outlet 150 is communicated with the second sub-chamber 120 , and the second outlet 160 is communicated with the third sub-chamber 130 .

[0052] The garbage slag enters the first sub-chamber 110 through the feed port and is stratified under the action of the pulsating water flow. The slag components in the upper layer move to the second sub-chamber 120 through the first through hole 331, and the slag components in the lower layer move to the third sub-chamber 130 through the second through hole 332.

[0053] The discharge plate 340 is provided with a water outlet hole, which runs through the top and bottom. A one-way valve 350 is provided in the water outlet hole. The flow direction of the one-way valve 350 is from top to bottom. Therefore, water can only flow from top to bottom through the one-way valve 350, and the one-way valve 350 will prevent water from flowing from bottom to top. It can be understood that the water outlet hole and the one-way valve 350 on the discharge plate 340 can be provided with one or two or more.

[0054] The sealing plate 410 covers the second through hole 332, and the upper end of the sealing plate 410 can be hinged to the partition 330 by a hinge shaft, hinge, etc. The second through hole 332 is a stepped hole, so that the sealing plate 410 completely blocks the second through hole 332 after being swung clockwise into place. Figure 1 As shown, when the sealing plate 410 rotates clockwise by a certain angle, the sealing plate 410 blocks the second through hole 332, so that water and the slag components in the lower layer cannot pass through the second through hole 332; when the sealing plate 410 rotates counterclockwise by a certain angle, the sealing plate 410 opens the second through hole 332, so that part of the water and part of the slag components in the lower layer can pass through the second through hole 332. In this embodiment, the hinge between the sealing plate 410 and the partition plate 330 is set in the third sub-chamber 130.

[0055] Furthermore, a sealing ring is provided on the contact surface between the sealing plate 410 and the second through hole 332. It is understandable that the sealing ring can be provided only on the peripheral wall surface of the sealing plate 410 or the second through hole 332, or on both. The provision of the sealing ring improves the sealing effect and prevents water leakage from the second through hole 332 when the sealing plate 410 blocks the second through hole 332. Of course, since the discharge plate 340 is provided with a one-way valve 350, the water in the third sub-cavity 130 can flow to the fourth sub-cavity 140 through the one-way valve 350, and therefore, water leakage from the second through hole 332 is also allowed.

[0056] The reset component is a torsion spring or a compression spring. The reset component is disposed between the sealing plate 410 and the partition plate 330, and the function of the reset component is to drive the sealing plate 410 to block the second through hole 332. It is understandable that an appropriate torsion spring or compression spring can be selected so that when the lower layer of slag components on the first screen plate 310 accumulates to a certain amount, the torsion spring or compression spring can be overcome to drive the sealing plate 410 to swing counterclockwise at a certain angle.

[0057] When the reset component is a torsion spring, the torsion spring is sleeved at the hinge between the sealing plate 410 and the partition 330, one end of the torsion spring is fixedly connected to the sealing plate 410, and the other end of the torsion spring is fixedly connected to the partition 330, so that the sealing plate 410 swings clockwise by itself under the torsion force of the torsion spring until the second through hole 332 is blocked.

[0058] When the reset component is a compression spring, the lower end of the compression spring is fixedly connected to the sealing plate 410 , and the upper end of the compression spring is fixedly connected to the partition 330 . The compression spring can drive the sealing plate 410 to swing and enable the sealing plate 410 to block the second through hole 332 .

[0059] In this embodiment, a compression spring is selected as the reset component, and a mounting seat is provided on the right side of the partition 330 , the mounting seat is located in the third sub-cavity 130 , the upper end of the compression spring is connected to the mounting seat, and the lower end of the compression spring is connected to the right side of the sealing plate 410 .

[0060] The pulsating device 200 is arranged at the lower part of the cavity, and the function of the pulsating device 200 is to generate a pulsating water flow. When the first sub-cavity 110 and the fourth sub-cavity 140 are filled with water, the pulsating device 200 is started, and the pulsating device 200 can generate a pulsating water flow, so that the garbage slag in the first sub-cavity 110 is layered, and the slag components of the upper layer will pass through the first through hole 331 with the flow of part of the water and enter the second sub-cavity 120, thereby realizing the separation of the slag components of the upper and lower layers.

[0061] It is understandable that there may be some air between the lower surface of the discharge plate 340 and the fourth sub-chamber 140, or there may be no air. In this embodiment, the structure of the pulsation device 200 includes a paddle wheel and a rotary drive component. Among them, the paddle wheel includes a paddle wheel shaft 210 and a plurality of paddle wheel blades 220, all of which are evenly arranged around the circumference of the paddle wheel shaft 210, and a groove is provided on the back of each paddle wheel blade 220. The central axis of the paddle wheel shaft 210 extends in the front-to-back direction, and the rotary drive component may include a motor and a reducer, and the motor is connected to the paddle wheel shaft 210 through the reducer. When the motor is running, the paddle wheel will rotate clockwise to guide the water flow from bottom to top, and the water flow will lift the slag component with low density, and the slag component with high density will sink on the first screen plate 310.

[0062] During the operation of the jigger, the garbage slag enters the first sub-chamber 110 of the shell 100 from the feed port and falls on the first screen plate 310. At this time, the water volume in the shell 100 reaches the set requirement, and the pulsating device 200 runs and generates a pulsating water flow. Under the action of the pulsating water flow, the garbage slag will be stratified according to specific gravity, and the slag components located in the upper layer will flow to the second screen plate 320 through the first through hole 331 under the driving action of the water flow. Then, at least a part of the water will flow downward through the second screen plate 320 due to gravity, and can flow back to the fourth sub-chamber 140 from the one-way valve 350 of the discharge plate 340, and the slag components will move along the second screen plate 320 due to gravity and leave the shell 100 through the first outlet 150.

[0063] Since the first screen plate 310 is arranged at an angle, and the upper end of the sealing plate 410 is hinged to the partition plate 330, and the second through hole 332 is blocked by the action of the reset assembly, as the working time increases, the slag components of the lower layer will accumulate more and more on the first screen plate 310. When the slag components of the lower layer accumulate to a certain amount, this part of the slag components can exert a force on the sealing plate 410 under the action of its own gravity, and overcome the action of the reset assembly, driving the sealing plate 410 to swing counterclockwise by itself and open the second through hole 332, so that the slag components of the lower layer can fall down to the discharge plate 340 through the second through hole 332 due to the action of gravity, thereby reducing the accumulation of the lower side slag components on the first screen plate 310, so as to allow more garbage slag to enter the shell 100 through the feed port. At the same time, it is convenient to remove the lower layer of slag components from the second outlet 160. At this time, it does not affect the operation of the jig machine, and the lower layer of slag components on the first screen plate 310 can be easily removed without stopping the machine, thereby improving the working continuity of the jig machine and helping to improve the working efficiency of the garbage slag treatment system.

[0064] It can be understood that after part of the lower layer slag components are transferred from the first sub-chamber 110 to the third sub-chamber 130, the accumulation amount of the lower layer slag components on the first screen plate 310 is reduced to a certain amount, so that the sealing plate 410 swings clockwise by itself under the action of the reset assembly and blocks the second through hole 332 until the accumulation amount of the lower layer slag components accumulates to a certain amount again, and the second through hole 332 can be opened again.

[0065] Moreover, the reset component is configured as a torsion spring or a compression spring, which does not require power supply and wiring layout considerations, thereby avoiding water-electricity contact accidents and reducing the manufacturing cost and operating energy consumption of the jig.

[0066] like Figures 2 to 4 As shown, according to the jig of the second embodiment of the utility model, a first baffle 430 and a first driving assembly are added on the basis of the above embodiment.

[0067] The first baffle 430 covers the first outlet 150 provided on the housing 100, and the upper end of the first baffle 430 is hinged to the housing 100 through a hinge shaft. The first driving assembly is provided between the first baffle 430 and the housing 100, and the function of the first driving assembly is to drive the first baffle 430 to swing and block the first outlet 150. The first driving assembly is a torsion spring, a compression spring or a telescopic cylinder. The first outlet 150 is a stepped hole.

[0068] It is understandable that when the first driving component selects a torsion spring, the torsion spring is sleeved on the hinge shaft between the first baffle 430 and the housing 100, one end of the torsion spring is fixedly connected to the first baffle 430, and the other end of the torsion spring is fixedly connected to the housing 100. When the first driving component selects a compression spring, the upper end of the compression spring is fixedly connected to the outer peripheral wall of the housing 100, and the lower end of the compression spring is fixedly connected to the right side of the first baffle 430. In the case where the first driving component is a torsion spring or a compression spring, when the upper layer of slag components on the second screen plate 320 accumulates to a certain amount, it can overcome the action of the first driving component, drive the first baffle 430 to swing counterclockwise, and open the first outlet 150, so that part of the slag components fall down by themselves due to gravity and leave the cavity of the housing 100.

[0069] When the first driving assembly selects the telescopic cylinder, the cylinder portion of the telescopic cylinder is hinged to the mounting seat on the outer peripheral wall of the housing 100, and the rod portion of the telescopic cylinder is hinged to the first baffle 430. After the movable rod of the telescopic cylinder is extended, the first baffle 430 can rotate clockwise and block the first outlet 150. After the movable rod of the telescopic cylinder is retracted, the first baffle 430 can rotate counterclockwise and open the first outlet 150. In this case, the telescopic cylinder can be operated within a set time interval to drive the first baffle 430 to swing and control the opening and closing of the first outlet 150.

[0070] In this embodiment, the first drive assembly is arranged outside the cavity to facilitate maintenance and replacement of the first drive assembly.

[0071] With the above-mentioned structural setting, after the upper slag components are transferred from the first sub-chamber 110 to the second sub-chamber 120 with the water flow, the upper slag components are allowed to stay for a period of time, during which time the water is allowed to flow through the second sieve plate 320 and the one-way valve 350 of the discharge plate 340 and flow back to the fourth sub-chamber 140, thereby reducing the water flow out of the shell 100. Therefore, there is no need to frequently replenish water to the cavity of the shell 100, which can reduce energy consumption. In the second sub-chamber 120, as the working time increases, the upper slag components will move downward along the second sieve plate 320 and accumulate near the first baffle 430. After the accumulation reaches a certain value, the first baffle 430 can be opened to allow part of the upper slag components to pass through the first outlet 150.

[0072] In some embodiments, Figure 1 As shown, the discharge plate 340 is arranged horizontally. When the slag components of the lower layer are transferred from the first sub-chamber 110 to the third sub-chamber 130, the slag components of the lower layer will accumulate in the third sub-chamber 130, and the staff needs to take out the slag components in the third sub-chamber 130 manually or by a robot.

[0073] In other embodiments, Figure 3 As shown, the discharge plate 340 is arranged downwardly from left to right, and the one-way valve 350 is arranged at one end of the discharge plate 340 close to the second outlet 160. With such arrangement, after the sealing plate 410 is opened, the slag components of the lower layer will be transferred from the first sub-chamber 110 to the third sub-chamber 130 and fall on the discharge plate 340. At this time, the slag components of the lower layer will move downward along the discharge plate 340 due to gravity and leave the chamber through the second outlet 160. In this process, at least part of the water can flow back to the fourth sub-chamber 140 through the one-way valve 350. Of course, it is not ruled out that part of the water passes through the second outlet 160 with the slag components.

[0074] Further, such as Figures 2 to 4 As shown, the structure of the jig also includes a second baffle 450 and a second drive assembly. The second baffle 450 covers the second outlet 160 provided on the housing 100, and the upper end of the second baffle 450 is hinged to the housing 100 through a hinge shaft. The second drive assembly is provided between the second baffle 450 and the housing 100, and the function of the second drive assembly is to drive the second baffle 450 to swing and block the second outlet 160. The second drive assembly is a torsion spring, a compression spring or a telescopic cylinder. The second outlet 160 is a stepped hole. In this embodiment, the discharging plate 340 is arranged at an angle, and specifically, the discharging plate 340 is inclined downward from left to right.

[0075] It is understandable that when the second driving component selects a torsion spring, the torsion spring is sleeved on the hinge shaft between the second baffle 450 and the housing 100, one end of the torsion spring is fixedly connected to the second baffle 450, and the other end of the torsion spring is fixedly connected to the housing 100. When the second driving component selects a compression spring, the upper end of the compression spring is fixedly connected to the outer peripheral wall of the housing 100, and the lower end of the compression spring is fixedly connected to the right side of the second baffle 450. In the case where the second driving component is a torsion spring or a compression spring, when the lower layer of slag components on the discharge plate 340 accumulate to a certain amount, the second driving component can be overcome to drive the second baffle 450 to swing counterclockwise and open the second outlet 160, so that part of the slag components fall down by themselves due to gravity and leave the cavity of the housing 100.

[0076] When the second driving assembly selects the telescopic cylinder, the cylinder portion of the telescopic cylinder is hinged to the mounting seat on the outer peripheral wall of the housing 100, and the rod portion of the telescopic cylinder is hinged to the second baffle 450. After the movable rod of the telescopic cylinder is extended, the second baffle 450 can rotate clockwise and block the second outlet 160. After the movable rod of the telescopic cylinder is retracted, the second baffle 450 can rotate counterclockwise and open the second outlet 160. In this case, the telescopic cylinder can be operated within a set time interval to drive the second baffle 450 to swing and control the opening and closing of the second outlet 160.

[0077] In this embodiment, the second drive assembly is arranged outside the cavity to facilitate replacement and maintenance of the second drive assembly.

[0078] With the above-mentioned structural setting, after the slag components of the lower layer are transferred from the first sub-chamber 110 to the third sub-chamber 130 through the second through hole 332, the slag components of the lower layer are allowed to stay for a period of time. During this period of time, the water in the third sub-chamber 130 is allowed to flow back to the fourth sub-chamber 140 through the one-way valve 350 of the discharge plate 340, further reducing the water flow out of the shell 100. Therefore, there is no need to frequently replenish water to the cavity of the shell 100, which can reduce energy consumption. In the third sub-chamber 130, as the working time increases, the slag components of the lower layer will move downward along the discharge plate 340 and accumulate at a position close to the second baffle 450. After the accumulation reaches a certain value, the second baffle 450 can be opened to allow part of the slag components of the lower layer to pass through the second outlet 160.

[0079] like Figure 3As shown, in a specific example, the second through hole 332 of the housing 100 is provided with a rotatable sealing plate 410, and a first compression spring 420 is provided for the sealing plate 410, and the first compression spring 420 can drive the sealing plate 410 to automatically swing clockwise and block the second through hole 332. Moreover, the first outlet 150 of the housing 100 is provided with a rotatable first baffle 430, and the second outlet 160 of the housing 100 is provided with a rotatable second baffle 450, the first driving component is a second compression spring 470, which can drive the first baffle 430 to swing clockwise and block the first outlet 150, and the second driving component is a third compression spring 480, which can drive the second baffle 450 to swing clockwise and block the second outlet 160. With such a configuration, there is no need to consider the wiring layout, and electric energy is saved.

[0080] like Figure 2 As shown, in another specific example, a first baffle 430 and a second baffle 450 are respectively provided for the first outlet 150 and the second outlet 160 of the housing 100, and the first driving component is a first cylinder 440, and the second driving component is a second cylinder 460. The first cylinder 440 can be used to drive the first baffle 430 to swing quickly, so as to realize the rapid opening and rapid closing of the first outlet 150. The second cylinder 460 can be used to drive the second baffle 450 to swing quickly, so as to realize the rapid opening and rapid closing of the second outlet 160.

[0081] like Figures 1 to 3 As shown, in a specific example, the pulsation device 200 adopts a dial structure.

[0082] like Figure 4 As shown, in another specific example, the pulsation device 200 includes a flexible diaphragm 230, a lower cone bucket 240, a driving mechanism 250 and a buffer mechanism 260. The cavity penetrates the lower surface of the housing 100, the flexible diaphragm 230 is an annular structure, the upper end of the flexible diaphragm 230 is connected to the lower end of the housing 100, the lower end of the flexible diaphragm 230 is connected to the upper end of the lower cone bucket 240, the lower cone bucket 240 has a groove with an opening facing upward, and the lower cone bucket 240 is larger at the upper end and smaller at the lower end.

[0083] The driving mechanism 250 is a device for driving the lower cone bucket 240 to move linearly up and down, and an existing linear driving device can be used. The linear driving device includes a motor, an eccentric cam structure and a lifting rod. The output end of the motor is connected to the eccentric cam structure, the upper end of the lifting rod is connected to the lower end of the lower cone bucket 240, and the lower end of the lifting rod is in contact with the eccentric cam structure. It can be understood that when the motor drives the eccentric cam structure to rotate, since the lower end of the lifting rod will always abut against the eccentric cam structure, the eccentric cam structure can drive the lifting rod to move back and forth in the up and down direction, thereby realizing the back and forth up and down movement of the lower cone bucket 240, prompting the flexible diaphragm 230 to continuously deform, and then can play a role in generating pulsating water flow.

[0084] The buffer structure may include a plurality of springs extending in the up-down direction, the plurality of springs being evenly arranged, the upper end of each spring being connected to the housing 100, and the lower end of each spring being connected to the lower cone bucket 240. It is understandable that the arrangement of the springs can play a good buffering role in the upward movement and downward movement of the lower cone bucket 240.

[0085] According to the first embodiment of the second aspect of the utility model, the garbage slag treatment system includes the jigger of the first embodiment.

[0086] It is understandable that the structure of the garbage slag treatment system includes not only the jigger, but also a crusher, a shaking table, an aluminum selection machine, etc. In this embodiment, only the jigger structure of the garbage slag treatment system is improved, so other components of the garbage slag treatment system are not described.

[0087] The garbage slag treatment system adopts the jig machine of the above structure, which can treat the garbage slag, and has strong working continuity and high working efficiency, and can avoid the situation where the jig machine frequently stops and removes the slag components on the first screen plate 310.
