Description

Technical Field

[0001] This application relates to the field of waste treatment technology, and more specifically, to a grating plate unclogging device. Background Technology

[0002] In the waste-to-energy industry, the waste pit serves as the core area for waste storage and fermentation. Its bottom is equipped with a leachate grating to separate the solid components of the waste from the leachate, enabling efficient drainage of the leachate. The unobstructed flow of the leachate grating directly affects the fermentation effect: if the grating is blocked, the leachate cannot be drained in time, leading to "waterlogged waste," significantly reducing the calorific value of the waste entering the furnace, thus reducing power generation and causing significant economic losses.

[0003] However, the clogging problem of leachate grating is widespread and severe. In practice, gratings of different specifications require frequent unclogging. Current unclogging methods mainly rely on manual operation. However, the leachate channels where the gratings are located are confined spaces filled with toxic, harmful, flammable, and explosive gases such as hydrogen sulfide, carbon monoxide, and methane, and have low oxygen content. Manual entry poses extremely high risks of poisoning and explosion. Moreover, manual unclogging cannot completely remove the blockages in the grating pores, failing to meet the intelligent and efficient operation requirements of waste-to-energy incineration plants.

[0004] Therefore, how to automate the unblocking of waste pit grates to reduce operational safety hazards, ensure the smooth flow of grates, and improve the economic benefits and operational safety of waste incineration power generation is an issue that needs attention. Utility Model Content

[0005] In view of the above problems, this application provides a grating plate unblocking device to reduce operational safety hazards, ensure the smooth flow of the grating plate, and improve the economic benefits and operational safety of waste incineration power generation.

[0006] To achieve the above objectives, the following specific solutions are proposed:

[0007] A grating plate unblocking device includes a hydraulic cylinder, a connector, a dredging column fixing plate, a fixed plate, and several dredging columns;

[0008] The hydraulic cylinder is connected to the unblocking column fixing plate via the connecting piece;

[0009] The first end of each of the unblocking columns passes through and is fixed to the unblocking column fixing plate, and the second end of each of the unblocking columns passes through the fixing plate;

[0010] The second end of each of the aforementioned unblocking columns is a pointed tip;

[0011] Each of the aforementioned unblocking columns is parallel to the others, and the unblocking column fixing plate is parallel to the fixing plate.

[0012] Optionally, each of the unblocking columns, from its initial push limit to its second end, includes, in sequence, an extension unblocking section, a disruption unblocking section, and a flow guiding unblocking section, wherein the initial push limit is the position of the unblocking column at the fixed plate before the initial push;

[0013] The extension section is the second end, used to insert the garbage blocking the opening when the dredging column is inserted into the opening of the grating plate;

[0014] The destructive and unblocking section includes several sets of retractable destructive and unblocking structures. Each set of destructive and unblocking structures includes multiple spikes surrounding the side of the destructive and unblocking section. After the destructive and unblocking section enters the opening, the destructive and unblocking structure opens so that each spike inserts into the garbage blocking the opening at an angle of no more than 90° with the direction of travel.

[0015] The flow guiding and unblocking section is provided with a flow guiding gap. After the flow guiding and unblocking section enters the opening, the leachate that seeps out after the garbage blocking the opening is unblocked flows out of the opening along the flow guiding gap.

[0016] Optionally, each of the unblocking columns has a fitting at its second end, the fitting being a pointed structure with the tip of the pointed structure pointing outward from the second end.

[0017] Optionally, the connector is a hydraulic push plate, and each of the first ends of the unblocking column is equipped with a booster, and each booster is connected to the hydraulic push plate.

[0018] Optionally, each of the booster components is equipped with a pressure sensor, and each pressure sensor uploads the pressure data it monitors to the dredging control center in real time.

[0019] The grating unblocking device provided in this application, utilizing the above technical solution, includes a hydraulic cylinder, a connector, a dredging column fixing plate, a fixed plate, and several dredging columns. The hydraulic cylinder is connected to the dredging column fixing plate via the connector. The first end of each dredging column passes through and is fixed to the dredging column fixing plate, and the second end of each dredging column passes through the fixed plate. The second end of each dredging column is a pointed tip. The dredging columns are parallel to each other, and the dredging column fixing plate is parallel to the fixed plate. The hydraulic cylinder pushes the dredging column fixing plate, causing the dredging columns to move towards the opening. After the second end of the dredging column inserts into the garbage blocking the opening, the dredging column continues to pass through the opening. Therefore, the grating unblocking device can replace manual grating unblocking, avoiding the safety hazards of manual grating unblocking. The insertion of the dredging columns into the opening can effectively unblock the garbage in the opening, allowing leachate to flow smoothly out of the grating opening, ensuring the unobstructed flow of the grating, reducing waterlogged garbage, and increasing the calorific value of the garbage entering the furnace, thereby improving the economic benefits and operational safety of waste incineration power generation.

[0020] Furthermore, the second end of the unblocking column is designed with a pointed tip, making it easier to insert into the garbage blocking the opening and improving the unblocking efficiency of the grating plate unblocking device. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Figures 1(a)-1(c) are schematic diagrams of a device for clearing blockages in a grating according to an embodiment of this application. As shown in Figure 1, the grating clearing device may include:

[0028] Hydraulic cylinder 10, connector 20, dredging column fixing plate 30, fixed plate 40, and several dredging columns 50.

[0029] Specifically, the hydraulic cylinder 10 is a hydraulic actuator that converts hydraulic energy into mechanical energy to achieve linear reciprocating motion. The hydraulic cylinder 10 can be composed of core components such as cylinder barrel, cylinder bottom, piston, piston rod, cylinder head, and sealing device. The hydraulic cylinder 10 can be driven by pressurized oil, and the thrust or pull force is generated by the pressure difference on both sides of the piston to push the load to complete the predetermined action. It has the characteristics of simple structure, large output force, smooth movement, high reliability, and easy control.

[0030] The hydraulic cylinder 10 can be connected to the dredging column fixing plate 30 via the connector 20.

[0031] Specifically, the dredging column fixing plate 30 receives the power transmitted by the hydraulic cylinder 10 through the connector 20, so as to realize the synchronous and stable movement of multiple dredging columns 50.

[0032] The first end of each unblocking column 50 passes through and is fixed to the unblocking column fixing plate 30, and the second end of each unblocking column 50 passes through the fixing plate 40.

[0033] Specifically, the second end of the drain cleaning column 50 does not need to be fixed to the fixing plate 40. The fixing plate 40 is used to fix the extension and retraction direction of the drain cleaning column 50 during its extension and retraction movement, preventing the displacement direction / angle of the drain cleaning column 50 from shifting. Both the drain cleaning column fixing plate 30 and the fixing plate 40 are multi-hole designs, with the diameter of each hole slightly larger than the diameter of the drain cleaning column 50, so that the drain cleaning column 50 can pass through.

[0034] The unblocking column 50 is an element that is directly inserted into the opening of the grating plate that is clogged. It can be coated with anti-corrosion material to prevent corrosion from leachate seeping out during the unblocking process.

[0035] The second end of each unblocking column 50 is a pointed tip, which can be designed as a multi-faceted pyramid or a cone.

[0036] Understandably, the second end of the unblocking column 50 is designed with a pointed tip, allowing it to be inserted into the clogged debris more smoothly and with less resistance. This reduces wear on the unblocking column 50 itself, improves its durability, and thus increases the unblocking efficiency of the grating unblocking device.

[0037] Each dredging column 50 is parallel to the others, and the dredging column fixing plate 30 is parallel to the fixing plate 40.

[0038] Understandably, the hydraulic cylinder 10 moves the unblocking column fixing plate 30 closer to the fixed plate 40, thereby moving the parallel unblocking columns 50 towards the grid opening, thus replacing manual unblocking of the grid and avoiding the safety hazards of manual unblocking. When multiple unblocking columns 50 are inserted into the garbage blocking the opening, leachate will seep out and flow out of the grid opening, ensuring the unobstructed flow of the grid, reducing waterlogged garbage, increasing the calorific value of the garbage entering the furnace, and thus improving the economic benefits and operational safety of waste incineration power generation.

[0039] The grating unblocking device provided in this embodiment includes a hydraulic cylinder, a connector, a dredging column fixing plate, a fixing plate, and several dredging columns. The hydraulic cylinder is connected to the dredging column fixing plate via the connector. The first end of each dredging column passes through and is fixed to the dredging column fixing plate, and the second end of each dredging column passes through the fixing plate. The second end of each dredging column is a pointed tip. The dredging columns are parallel to each other, and the dredging column fixing plate is parallel to the fixing plate. The hydraulic cylinder pushes the dredging column fixing plate, causing the dredging columns to move towards the opening. After the second end of the dredging column inserts into the garbage blocking the opening, the dredging column continues to pass through the opening. Therefore, the grating unblocking device can replace manual grating unblocking, avoiding the safety hazards of manual grating unblocking. The insertion of the dredging columns into the opening can effectively clear the garbage from the opening, allowing leachate to flow smoothly out of the grating opening, ensuring the unobstructed flow of the grating, reducing waterlogged garbage, and increasing the calorific value of the garbage entering the furnace, thereby improving the economic benefits and operational safety of waste incineration power generation.

[0040] Furthermore, the second end of the unblocking column is designed with a pointed tip, making it easier to insert into the garbage blocking the opening and improving the unblocking efficiency of the grating plate unblocking device.

[0041] To further improve the unblocking efficiency of the grating plate unblocking device, the design of the unblocking column can be further optimized from the unblocking column entry stage, the unblocking stage after the unblocking column enters the opening, and the leachate diversion stage. Based on this, some embodiments of this application further describe the unblocking column mentioned in the above embodiments. Specifically, each unblocking column 50, from its initial push-limiting to its second end unblocking segment, sequentially includes an insertion unblocking segment, a disrupting unblocking segment, and a diversion unblocking segment, such as... Figure 2 As shown.

[0042] The initial push limit is the position of the dredging column at the fixed plate 40 before the initial push.

[0043] The second end, which extends into the dredging section, is used to insert the garbage blocking the opening when the dredging column 50 is inserted into the opening of the grating plate.

[0044] Understandably, the second end is a pointed tip, making it easier to insert into the debris blocking the hole, while reducing wear on the 50-inch unblocking column, thus making the unblocking process smoother.

[0045] The deblocking section may include several sets of retractable deblocking structures. Each set of deblocking structures may include multiple spikes surrounding the side of the deblocking section. After the deblocking section enters the opening, the deblocking structure opens so that each spike inserts into the debris blocking the opening at an angle not greater than 90° to the direction of travel.

[0046] like Figure 2 As shown, assuming the grate opening blocked by garbage is located on the left, the unblocking section moves to the left. After the unblocking section enters the opening, it opens the unblocking structure with multiple spikes. Since the forward direction of the spikes is no more than 90° from the direction of the spikes, the spikes penetrate the blocked garbage with more destructive force, thereby causing strong damage to the blocked garbage and further enhancing the unblocking effect.

[0047] In addition, the dredging structure can be connected to a rotating drive mechanism, which can drive each spike to rotate at high speed around the dredging column 50 when needed, so as to destroy the surrounding garbage in all directions and further enhance the dredging effect.

[0048] The diversion and dredging section is equipped with a diversion gap. After the diversion and dredging section enters the opening, the leachate that seeps out after the garbage blocking the opening is cleared flows out of the opening along the diversion gap.

[0049] It is understandable that the powerful unblocking of the blockage due to the disruptive dredging structure may result in a large amount of leachate flowing out. Therefore, a flow guide gap can be set in the flow guide section. The flow guide gap can form a channel for the leachate to flow out of the hole, allowing the leachate to flow out of the hole along the channel, thus achieving a better flow guide effect.

[0050] In order to further reduce the wear on the end face of the unblocking column 50, some embodiments of this application further describe the second end of the unblocking column 50 mentioned in the above embodiments. Specifically, the second end of each unblocking column 50 may be fitted with an insertion connector.

[0051] Specifically, the insertion connector can be a pointed structure. The tip of the pointed structure points outward from the second end.

[0052] More specifically, the insertion connector can be pyramidal or conical.

[0053] Understandably, the second end of the drain column 50 needs to repeatedly impact the debris in the hole, which will wear down or aggravate wear over time. By regularly replacing the insertion connector, the wear is transferred to the insertion connector, which further reduces the operating cost of the drain column 50 and extends its service life.

[0054] Considering that the unblocking column 50 may not be able to effectively clear the blockage in one go when pushing the severely clogged garbage, the reaction force of the unblocking column 50 on the clogged garbage pile increases rapidly. At the same time, since the first end of the unblocking column 50 is fixed to the unblocking column fixing plate 30 by ordinary welding (refer to Figure 1(a)), the impact of the huge reaction force may cause the first end of the unblocking column 50 to detach from the unblocking column fixing plate 30, which may damage other structures of the grating plate unblocking device. Based on this, some embodiments of this application further describe the grating plate unblocking device mentioned in the above embodiments.

[0055] Specifically, the connector 20 can be a hydraulic push plate, and each unblocking column 50 has a booster at its first end, with each booster connected to the hydraulic push plate.

[0056] Understandably, the connector 20 is a component used to connect the hydraulic cylinder 10 and the dredging column fixing plate 30. When the connector 20 is a hydraulic push plate, it can provide sufficient support force for the dredging column fixing plate 30. At this time, an auxiliary pusher is provided at the first end of the dredging column 50. Since the auxiliary pusher is connected to the hydraulic push plate, when the dredging column 50 fails to push the garbage and the reaction force increases rapidly, the auxiliary pusher at the first end of the dredging column 50 can be supported by the hydraulic push plate to offset part of the reaction force, thereby reducing the possibility of damage between the first end of the dredging column 50 and the dredging column fixing plate 30.

[0057] In some embodiments of this application, in order to more clearly measure the risk of the first end of the unblocking column 50 being damaged and separated from the unblocking column fixing plate 30, a pressure sensor can be connected to the booster mentioned in the aforementioned embodiments. Then the pressure sensor can upload the pressure data it monitors to the unblocking control center in real time.

[0058] Specifically, when the unblocking column 50 fails to push the debris, causing the reaction force to increase rapidly, the unblocking control center can assess whether to allow the unblocking column 50 to continue forward (continue unblocking) based on the detected reaction pressure value. If the detected reaction pressure value indicates a high risk of damage or breakage between the first end of the unblocking column 50 and the unblocking column fixing plate 30, the unblocking column 50 can be controlled to stop forward insertion or retract; if the reaction pressure value does not reach the safety risk value, the unblocking column 50 can continue to perform unblocking work.

[0059] Based on the grating unblocking device described in the foregoing embodiments, this application provides a grating unblocking system. The grating unblocking system may include a grating unblocking device and a dredging control center.

[0060] Specifically, the grating unblocking device can be installed at the corresponding location on the grating of the waste pit. The grating contains multiple openings.

[0061] Next, this application embodiment describes the process of the unblocking control center of the grating plate unblocking system controlling a single unblocking action.

[0062] The dredging control center can drive the hydraulic cylinder 10 to push the dredging column fixing plate 30, so that the dredging column fixing plate 30 drives the dredging column 50 to move towards the hole until the second end of the dredging column 50 inserts the garbage blocking the hole, and then the dredging column 50 continues to pass through the hole.

[0063] When the distance between the unblocking column fixing plate 30 and the fixed plate 40 is less than the preset distance threshold, the hydraulic cylinder 10 is driven to retract the unblocking column fixing plate 30 so that the unblocking column 50 retracts to the standby position and completes one unblocking action of the grid plate.

[0064] Taking the unblocking column 50 as a reference, the unblocking action of a single grating plate can be "standby position → move to the maximum limited position → return to standby position".

[0065] It is understandable that each unblocking action performed by the grating plate unblocking device requires a certain moving distance of the unblocking column 50. Specifically, the distance between the unblocking column fixing plate 30 and the fixed plate 40 can be used as the standard. The preset distance threshold can represent the maximum value of the reduction in the distance between the unblocking column fixing plate 30 and the fixed plate 40 caused by the movement of the unblocking column 50.

[0066] Furthermore, a first distance sensor and a second distance sensor can be installed on the dredging column fixing plate 30 and the fixed plate 40 respectively. The first distance sensor and the second distance sensor can transmit distance data to the dredging control center at the same time. The two distance sensors can play a mutual detection role. If the distance values ​​of the two distance sensors are different, the dredging control center can use fixed distance control to control the maximum moving length of the dredging column 50.

[0067] To further improve the unblocking efficiency of the grating unblocking system, further optimization can be made from the unblocking stage after the unblocking column enters the opening. Based on this, some embodiments of this application further describe the grating unblocking system mentioned in the above embodiments. Specifically, each unblocking column 50, from its initial push-limiting to its second end unblocking segment, sequentially includes an insertion unblocking segment, a disrupting unblocking segment, and a guiding unblocking segment, such as... Figure 2 As shown.

[0068] The initial push limit is the position of the dredging column at the fixed plate 40 before the initial push.

[0069] The deblocking section can include several sets of retractable deblocking structures. Each set of deblocking structures can include multiple spikes surrounding the side of the deblocking section. After the deblocking section enters the opening, the deblocking control center can drive the deblocking structures to open, so that each spike inserts into the debris blocking the opening at an angle not greater than 90° to the direction of travel.

[0070] Furthermore, the dredging structure can be connected to a rotating drive mechanism, and the dredging control center can drive each spike to rotate at high speed around the dredging column 50 to destroy the surrounding garbage in all directions, which can further enhance the dredging effect.

[0071] Considering that the unblocking column 50 may not be able to effectively clear the blockage in one go when pushing the severely clogged garbage, the reaction force of the unblocking column 50 on the clogged garbage pile increases rapidly. At the same time, since the first end of the unblocking column 50 is fixed to the unblocking column fixing plate 30 by ordinary welding (refer to Figure 1(a)), the impact of the huge reaction force may cause the first end of the unblocking column 50 to detach from the unblocking column fixing plate 30, which may damage other structures of the grating plate unblocking device. Based on this, some embodiments of this application further describe the grating plate unblocking system mentioned in the above embodiments.

[0072] The connector 20 can be a hydraulic push plate, and each unblocking column 50 is equipped with a booster at its first end, with each booster connected to the hydraulic push plate. The booster is connected to a pressure sensor, which can then upload the monitored pressure data to the unblocking control center in real time.

[0073] Understandably, the connector 20 is a component used to connect the hydraulic cylinder 10 and the dredging column fixing plate 30. When the connector 20 is a hydraulic push plate, it can provide sufficient support force for the dredging column fixing plate 30. At this time, an auxiliary pusher is provided at the first end of the dredging column 50. Since the auxiliary pusher is connected to the hydraulic push plate, when the dredging column 50 fails to push the garbage and the reaction force increases rapidly, the auxiliary pusher at the first end of the dredging column 50 can be supported by the hydraulic push plate to offset part of the reaction force, thereby reducing the possibility of damage between the first end of the dredging column 50 and the dredging column fixing plate 30.

[0074] Specifically, when the unblocking column 50 is driven to move, the unblocking control center monitors the pressure data of each pressure sensor. For each pressure sensor, if the pressure data exceeds the pressure threshold, the unblocking control center stops driving the hydraulic cylinder to push, or drives the hydraulic cylinder to retract the unblocking column fixing plate.

[0075] Considering that the actual unblocking speed needs to be determined based on the degree of blockage in the garbage pit during the actual unblocking process—for example, if the garbage pit is severely blocked, the unblocking speed needs to be increased; otherwise, the basic speed can be maintained—the unblocking speed of the grating plate unblocking device needs to be flexibly adjusted. Based on this, in some embodiments of this application, a level gauge can be installed in the garbage pit. This level gauge can monitor the level of leachate in the garbage pit in real time to indicate the blockage situation and transmit the level data to the unblocking control center. Therefore, the process of the unblocking control center controlling the grating plate unblocking device to perform the unblocking action, as mentioned in the aforementioned embodiments, can further include:

[0076] After each unblocking operation is completed, the leachate level value in the waste pit is obtained from the real-time monitoring of the leachate by the level gauge.

[0077] Understandably, if the liquid level in the waste pit is too high, it means that the grating plate cleaning device needs to speed up the cleaning process. In order to control the cleaning speed of the grating plate cleaning device more flexibly and accurately, it is necessary to monitor the real-time liquid level of the leachate in the waste pit after each cleaning action.

[0078] The cleaning time for completing one cleaning operation of the bar screen is updated based on the leachate level.

[0079] Specifically, the leachate level can be divided by the standard level to obtain the standard level difference ratio. Then, the standard cleaning time can be divided by the standard level difference ratio to obtain the updated cleaning time for completing one cleaning operation of the bar screen.

[0080] The standard cleaning time can be defined as the standard time for cleaning a blockage when the leachate level in the landfill is at the standard level value.

[0081] For example, under standard operating conditions, if the standard leachate level in a landfill is 1.0L, a standard cleaning time of 1.0T should be used to complete one cleaning operation of the bar screen. However, if the leachate level is found to be 1.6L after a cleaning operation, the standard level difference ratio is calculated to be 1.6L / 1.0L = 1.6. Dividing the standard cleaning time of 1.0T by this ratio yields an updated cleaning time of 1.0T / 1.6 = 0.625T for the next cleaning operation. In other words, the time needs to be adjusted / shortened to 0.625T to complete the next cleaning operation.

[0082] The congestion clearing action is executed according to the congestion clearing time.

[0083] The grating plate unblocking system provided in this embodiment monitors the real-time leachate level information in the landfill pit and flexibly adjusts the unblocking time of the grating plate unblocking device to perform the unblocking action, ensuring that the grating plate unblocking work in the landfill pit is not delayed.
