Description

Technical Field

[0001] This utility model belongs to the technical field of slag removal machine, and in particular relates to an automatic water replenishment device for slag removal machine to prevent blockage. Background Technology

[0002] Ash removal machines are often used in high-temperature environments (such as the tail end of a boiler). In such environments, the water in the water circulation system will continue to evaporate due to the high temperature, causing the water level to gradually drop. In order to maintain water quality or remove impurities, the system also needs to be drained regularly, which will also take away some water. At the same time, as a cooling medium, the sufficient presence of water is crucial to ensuring the cooling effect of ash and slag and to preventing overheating damage to the equipment.

[0003] First, traditional slag removal machines have obvious defects; their structure is too simple and lacks the necessary gentle slope structure, which makes it difficult for slag and water to flow smoothly in the tank and easily accumulate in dead corners, thus causing blockages; once a blockage occurs, not only will the normal transportation of slag be affected, but the equipment may also be overloaded, wear and tear will be accelerated, or even damaged.

[0004] Secondly, the water replenishment mechanism of traditional slag removal machines also has problems; its water replenishment operation often relies on manual judgment and operation, lacks intelligence and flexibility, and is difficult to achieve precise control of the water level in the tank; this leads to frequent situations of excessive or insufficient water in actual application, which not only wastes water resources, but also affects the normal operation of the slag removal machine.

[0005] In addition, traditional slag removal machines also show significant shortcomings in temperature control; due to the lack of an effective temperature monitoring and regulation mechanism, the liquid temperature in the tank is often difficult to maintain at a safe level; this not only affects the slag treatment effect, but may also cause thermal damage to the equipment, thereby shortening its service life. Utility Model Content

[0006] This utility model provides an automatic water replenishment device for preventing blockage in slag removal machines, aiming to solve the problems of existing slag removal machines having simple tank structures that are prone to blockage, unintelligent water replenishment mechanisms that lead to inaccurate water level control, and insufficient temperature control that can easily cause thermal damage to the equipment.

[0007] This utility model is implemented as follows: an automatic water replenishment device for preventing blockage of a slag remover includes a slag remover body, which includes a continuous slag conveying channel formed by connecting a horizontal section trough and an inclined section trough.

[0008] The first and last water supply tanks are respectively installed at the first and last ends of the horizontal section of the tank, and the first water supply tank is connected to a cooling water pipe.

[0009] The horizontal section of the tank has at least four rectangular overflow channels evenly distributed along its length.

[0010] The outside of the slag removal machine body is equipped with a main manifold that connects to multiple overflow channels;

[0011] An overflow box is connected to the bottom of the manifold.

[0012] The overflow box is equipped with an intercepting filter screen with an inclination angle of 40°-45°;

[0013] The overflow box is located on the bottom side of the intercepting filter screen with a low slope and is equipped with a slag collection trough.

[0014] The bottom of the overflow tank is connected to a return water pipe;

[0015] The end of the return water pipe furthest from the overflow tank is connected to the end water supply tank.

[0016] Preferably, at least four assembly slots are provided in the middle of the horizontal section of the tank along its length, and each assembly slot is embedded with a fiber Bragg grating level sensor, the axis of the fiber Bragg grating level sensor coinciding with the center line of the assembly slot.

[0017] Preferably, a float-type sensor is installed in the front area of ​​the horizontal section of the tank.

[0018] Preferably, both the first and last water supply tanks are connected to independent water pipes, and the outlets of the two independent water pipes extend to one-third of the longitudinal height of the horizontal section of the tank. Independent control valves are installed on both the independent water pipes and the return water pipes.

[0019] Preferably, the horizontal section of the trough is designed as a gentle slope structure with a longitudinal slope of ≤5°.

[0020] Preferably, the overflow box is connected to a slag collection bin on the outer side of the slag receiving trough, and a sealing cover is hinged to the upper end of the slag collection bin.

[0021] Preferably, a temperature sensor is installed inside the horizontal section of the tank.

[0022] Preferably, at least three sets of heat-conducting fins are provided on the outer side of the horizontal section of the slag removal machine body.

[0023] Preferably, a PLC controller is installed on the bottom side of the water supply tank at the first end, and the PLC controller is electrically connected to the temperature sensor, the independent control valve, the float sensor and the fiber optic level sensor.

[0024] Compared with the prior art, the embodiments of this application have the following main advantages:

[0025] Firstly, the device's gently sloping design in the horizontal section of the tank allows slag and water to slide down naturally under gravity without the need for additional power, fundamentally reducing the risk of blockage. Simultaneously, the overflow channels, evenly distributed along the length of the horizontal section, automatically overflow the slag-water mixture when the water level exceeds a certain height, further preventing blockage. Furthermore, the intercepting filter in the overflow box effectively separates slag and clean water, ensuring that only clean water continues to flow, while the intercepted slag slides into the slag receiving trough and eventually enters the slag collection bin for periodic cleaning.

[0026] Secondly, this device, through the coordinated operation of the front and rear water supply tanks, can replenish water to the slag removal machine body in a timely and effective manner, thereby avoiding the problems of excessive or insufficient water.

[0027] Thirdly, this device achieves precise control of the water level and temperature in the horizontal section of the tank. The fiber optic grating level sensor can continuously monitor water level changes and transmit the signal to the PLC controller. The PLC controller adjusts the water replenishment speed and flow rate according to the received signal to maintain a stable water level in the tank. At the same time, the temperature sensor can continuously monitor the temperature changes of the liquid in the tank and activate the corresponding adjustment mechanism when the temperature is too high or too low, such as adjusting the water replenishment flow rate, to ensure that the temperature in the tank is always kept at a safe level. In addition, the design of the heat-conducting fins accelerates the heat dissipation speed and avoids a large amount of water evaporation. Attached Figure Description

Detailed Implementation

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] This utility model embodiment provides an automatic water replenishment device for preventing blockage in a slag removal machine, such as... Figure 1-6 As shown, it includes a slag removal machine body 1, which includes a continuous slag conveying channel formed by the horizontal section trough 2 and the inclined section trough 3.

[0038] The first and last ends of the horizontal section tank 2 are respectively provided with a first-end water supply tank 4 and a last-end water supply tank 5, and the first-end water supply tank 4 is connected to a cooling water pipe 6.

[0039] The sidewall of the horizontal section of the tank 2 has at least four overflow channels 7 with rectangular cross sections evenly distributed along its length.

[0040] The outer side of the slag removal machine body 1 is provided with a main pipe 8 that is connected to multiple overflow channels 7;

[0041] The bottom of the main manifold 8 is connected to an overflow box 9;

[0042] An intercepting filter 10 is installed inside the overflow box 9, with an inclination angle of 40°-45°;

[0043] An overflow box 9 is located on the bottom side of the intercepting filter 10 with a lower slope and is equipped with a slag receiving trough 11.

[0044] The bottom of the overflow box 9 is connected to the return water pipe 12;

[0045] The end of the return water pipe 12 away from the overflow box 9 is connected to the tail end water supply box 5.

[0046] It should be noted that existing slag removal machines suffer from problems such as simple tank structure leading to easy clogging, unintelligent water replenishment mechanism resulting in inaccurate water level control, and insufficient temperature control causing thermal damage to the equipment. This solution fundamentally reduces the risk of clogging by designing a gentle slope structure in the horizontal section of the tank 2 and setting up an overflow channel 7. The intercepting filter 10 in the overflow box 9 effectively separates slag and clean water, ensuring clean water flow in the horizontal section of the tank 2. At the same time, the coordinated water replenishment mechanism of the first-end water supply tank 4 and the last-end water supply tank 5 ensures the stability of the water level in the horizontal section of the tank 2, avoiding problems of excessive or insufficient water. In addition, through the precise monitoring and control of the fiber optic level sensor 14 and the temperature sensor 20, as well as the heat dissipation design of the heat-conducting fins 21, the device can achieve dual precise control of the water level and temperature in the tank, further ensuring the safe and stable operation of the slag removal machine.

[0047] Specifically, in this embodiment, the solution mainly includes a slag removal machine body 1. The slag removal machine body 1 is connected by a horizontal section trough 2 and an inclined section trough 3 to form a continuous slag conveying channel for conveying and processing slag. On the outside of the horizontal section trough 2, a head water supply tank 4 and a tail water supply tank 5 are installed at its head and tail ends, respectively. The head water supply tank 4 is connected through a cooling water pipe 6 to provide a cooling water source for the slag removal machine body 1.

[0048] Along the length of the horizontal section of the tank 2, at least four overflow channels 7 are evenly distributed on its sidewalls; the design of these overflow channels 7 allows water or sludge-water mixture in the tank to automatically overflow when it exceeds a certain level, thereby preventing blockage; these overflowing sludge-water mixtures flow into the manifold 8.

[0049] The main manifold 8 collects the sludge-water mixture from all the overflow channels 7 and guides it to the overflow tank 9 below. Inside the overflow tank 9, an intercepting filter 10 with an inclination angle of 40°-45° is installed. The function of the intercepting filter 10 is to separate the sludge from the water flow, ensuring that only clean water can continue to flow through the intercepting filter 10.

[0050] Because the intercepting filter screen 10 has a certain tilt angle, the intercepted slag will slide down the slope of the intercepting filter screen 10 to its lower bottom side and accumulate in the slag receiving trough 11; the setting of the slag receiving trough 11 facilitates the regular cleaning and collection of these separated slag materials.

[0051] Meanwhile, clean water is transported back to the tail end water supply tank 5 through the return water pipe 12 at the bottom of the overflow tank 9, forming a closed-loop water replenishment system in which the clean water is recycled, which not only maintains the water level in the tank of the slag remover body 1, but also effectively prevents blockage.

[0052] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, at least four assembly slots 13 are provided in the middle of the horizontal section of the tank 2 along its length. Each assembly slot 13 is embedded with a fiber optic grating level sensor 14, and the axis of the fiber optic grating level sensor 14 coincides with the center line of the assembly slot 13.

[0053] In this embodiment, the assembly tank 13 provides an installation position for the fiber Bragg grating level sensor 14, ensuring the stability and accuracy of the equipment. The axis of the fiber Bragg grating level sensor 14 is completely aligned with the center line of the assembly tank 13, which means that the fiber Bragg grating level sensor 14 can accurately measure and sense the changes in the liquid level in the horizontal section tank 2. When the water level in the horizontal section tank 2 rises or falls, the fiber Bragg grating level sensor 14 can capture these changes in real time and convert them into electrical signals for transmission to the PLC controller 22.

[0054] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, a float sensor 15 is installed in the front area of ​​the horizontal section of the tank 2.

[0055] In this embodiment, when the liquid level in the horizontal section of the tank 2 changes, the float will rise or fall accordingly, thereby accurately determining the liquid level in the tank.

[0056] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, both the first water supply tank 4 and the last water supply tank 5 are connected to independent water pipes 16. The outlets of the two independent water pipes 16 extend to one-third of the longitudinal height of the horizontal section of the tank 2. Independent control valves 17 are installed on both the independent water pipes 16 and the return water pipe 12.

[0057] In this embodiment, when the water level in the horizontal section tank 2 drops below the preset safety range, the PLC controller 22 will issue a command to open the independent control valve 17 corresponding to the first water supply tank 4, so that water flows from the first water supply tank 4 into the tank through the independent water pipe 16; at the same time, according to the actual water level in the horizontal section tank 2, the PLC controller 22 can also adjust the opening of the independent control valve 17 to control the water replenishment speed and flow rate.

[0058] During the water replenishment process, the treated clean water will flow back to the tail end water supply tank 5 through the return water pipe 12, forming a closed-loop water replenishment system. When the water level in the horizontal section tank 2 is too high, the PLC controller 22 will open the independent control valve 17 on the return water pipe 12 to allow the excess water to flow back to the tail end water supply tank 5, thereby maintaining the water level in the tank.

[0059] Thanks to the presence of the independent control valve 17, operators can flexibly adjust the flow rate and speed of the water according to actual needs to adapt to different working scenarios and requirements.

[0060] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, the horizontal section of the trough 2 is designed as a gentle slope structure with a longitudinal slope of ≤5°.

[0061] In this embodiment, due to the presence of the gentle slope structure, the slag and water in the horizontal section of the trough 2 can slide down naturally under the action of gravity without the need for additional power support. This smooth flow helps to reduce the risk of blockage and improve the operating efficiency of the slag remover.

[0062] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, the overflow box 9 is connected to the outer side of the slag receiving trough 11, and the upper end face of the slag receiving trough 18 is hinged with a sealing cover 19.

[0063] In this embodiment, after the intercepting filter 10 separates the slag from the water flow, the slag slides down the inclined slope of the filter screen into the slag receiving trough 11. As the slag accumulates, it enters the slag collecting bin 18 through the connection between the slag receiving trough 11 and the slag collecting bin 18. In the non-cleaning state, the sealing cover 19 of the slag collecting bin 18 fits tightly against the upper surface, effectively preventing the entry of impurities such as dust and moisture. This helps to keep the inside of the slag collecting bin 18 clean and dry, preventing the slag from being contaminated or deteriorated.

[0064] When the slag collection bin 18 needs to be cleaned, the operator can easily open the sealing cover 19 to pour out the slag or perform other treatments; after cleaning, the sealing cover 19 can be put back on to restore the normal use of the slag collection bin 18.

[0065] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, a temperature sensor 20 is installed inside the horizontal section of the tank 2.

[0066] In this embodiment, the temperature sensor 20 can continuously monitor the temperature change of the liquid in the tank. The PLC controller 22 can determine whether the temperature of the liquid in the horizontal section tank 2 is within the preset safe range based on the received temperature signal. If the temperature is too high or too low, the PLC controller 22 will immediately start the corresponding adjustment mechanism, such as adjusting the water supply flow rate, to ensure that the temperature in the horizontal section tank 2 is always kept at a safe level.

[0067] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, at least three sets of heat-conducting fins 21 are provided on the outer side of the horizontal section of the slag removal machine body 1.

[0068] In this embodiment, when the temperature of the water or slag in the horizontal section of the tank 2 rises, the heat will be transferred to the heat-conducting fins 21 on the outside through the tank wall. Due to its high thermal conductivity, the heat-conducting fins 21 can quickly disperse the heat to a larger surface area, thereby accelerating the heat dissipation rate and preventing a large amount of water from evaporating.

[0069] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, a PLC controller 22 (S7-1214C PN) is installed on the bottom side of the first water supply tank 4. The PLC controller 22 is electrically connected to the temperature sensor 20 (PT100), the independent control valve 17, the float sensor 15 (YF-3000), and the fiber optic level sensor 14 (FGB-T-050).

[0070] In this embodiment, the device achieves precise control of the water level and temperature in the horizontal section tank 2 through real-time monitoring by the fiber Bragg grating level sensor 14 and the temperature sensor 20. The fiber Bragg grating level sensor 14 can continuously monitor water level changes and transmit the signal to the PLC controller 22. The PLC controller 22 adjusts the water replenishment rate and flow rate according to the received signal to maintain a stable water level in the tank. At the same time, the temperature sensor 20 can continuously monitor the temperature changes of the liquid in the tank. When the temperature is too high or too low, the PLC controller 22 activates the corresponding adjustment mechanism, such as adjusting the water replenishment flow rate, to ensure that the temperature in the tank is always kept at a safe level. In addition, the design of the heat-conducting fins 21 also accelerates the heat dissipation rate and avoids a large amount of water evaporation.

[0071] Working principle: The slag removal machine body 1 of this device is formed by connecting the horizontal section trough 2 and the inclined section trough 3 to form a continuous slag conveying channel for conveying and processing slag. The horizontal section trough 2 adopts a gentle slope structure design, which allows the slag and water in the trough to slide down naturally under the action of gravity without the need for additional power support, effectively reducing the risk of blockage and improving the operating efficiency of the slag removal machine.

[0072] On the outside of the horizontal section tank 2, a head water supply tank 4 and a tail water supply tank 5 are installed at its head and tail ends respectively. The head water supply tank 4 is connected to the cooling water pipe 6 to provide cooling water for the slag removal machine body 1. The tail water supply tank 5 is connected to the return water pipe 12 to jointly maintain the water level stability in the horizontal section tank 2.

[0073] Along the length of the horizontal section of the tank 2, at least four overflow channels 7 are evenly distributed on its sidewalls; these overflow channels 7 allow the sludge-water mixture in the tank to automatically overflow when it exceeds a certain level, preventing blockage; the overflowed sludge-water mixture flows into the manifold 8, and is then guided by the manifold 8 to the overflow box 9 below.

[0074] Inside the overflow tank 9, an intercepting filter 10 with an inclination angle of 40°-45° is installed. The function of the intercepting filter 10 is to separate the slag from the water flow, ensuring that only clean water can continue to flow through the intercepting filter 10. The intercepted slag will slide down the slope of the intercepting filter 10 to its lower bottom side and accumulate in the slag receiving trough 11. The slag receiving trough 11 is designed to facilitate the regular cleaning and collection of these separated slag. As the slag accumulates, it will enter the slag collecting bin 18 through the connection between the slag receiving trough 11 and the slag collecting bin 18. In the non-cleaning state, the sealing cover 19 of the slag collecting bin 18 is tightly fitted to the upper end face, effectively preventing the entry of impurities such as dust and water vapor, and keeping the inside of the slag collecting bin 18 clean and dry.

[0075] When the slag collection bin 18 needs to be cleaned, the operator can easily open the sealing cover 19 to pour out the slag or perform other treatments. After cleaning, the sealing cover 19 is put back on to restore the normal use of the slag collection bin 18. At the same time, clean water is transported back to the tail end water supply tank 5 through the return water pipe 12 at the bottom of the overflow tank 9, forming a closed-loop water replenishment system. In this way, the water level in the tank of the slag removal machine body 1 is kept stable, and blockage is effectively prevented.

[0076] In the slag removal machine body 1, a fiber optic grating liquid level sensor 14 is also installed. The fiber optic grating liquid level sensor 14 is installed through the assembly groove 13, and its axis is completely coincident with the center line of the assembly groove 13, which ensures the accuracy and stability of the measurement. The fiber optic grating liquid level sensor 14 can continuously monitor the liquid level changes in the horizontal section of the tank 2. When the water level rises or falls, the fiber optic grating liquid level sensor 14 can capture these changes in real time and convert them into electrical signals for transmission to the PLC controller 22.

[0077] The PLC controller 22 precisely controls the slag remover based on the received liquid level signal and temperature signal from the temperature sensor 20. When the water level in the horizontal section tank 2 drops below the preset safety range, the PLC controller 22 issues a command to open the independent control valve 17 corresponding to the first-end water supply tank 4, allowing water to flow from the first-end water supply tank 4 into the tank through the independent water pipe 16. At the same time, based on the actual water level in the horizontal section tank 2, the PLC controller 22 can also adjust the opening of the independent control valve 17 to control the water replenishment speed and flow rate.

[0078] During the water replenishment process, the treated clean water will flow back to the tail end water supply tank 5 through the return water pipe 12, forming a closed-loop water replenishment system. When the water level in the horizontal section tank 2 is too high, the PLC controller 22 will open the independent control valve 17 on the return water pipe 12 to allow the excess water to flow back to the tail end water supply tank 5, thereby maintaining the water level in the tank.

[0079] In addition, the temperature sensor 20 can continuously monitor the temperature changes of the liquid in the tank. When the temperature is too high or too low, the PLC controller 22 will immediately activate the corresponding adjustment mechanism, such as adjusting the water supply flow rate, to ensure that the temperature in the horizontal section tank 2 is always kept at a safe level. At the same time, when the temperature of the water flow or slag in the horizontal section tank 2 rises, the heat will be transferred to the heat-conducting fins 21 on the outside through the tank wall. With its high thermal conductivity, the heat-conducting fins 21 can quickly disperse the heat to a larger surface area, thereby accelerating the heat dissipation rate and preventing a large amount of water evaporation.
