Description

Technical Field

[0001] This application belongs to the technical field of water spraying and dust suppression for port bulk cargo loading and unloading, specifically relating to an outdoor water storage tank for mobile port machinery. Background Technology

[0002] In port loading and unloading operations of dry bulk cargo such as coal and ore, mobile port machinery such as stackers, reclaimers, and ship loaders need to be equipped with water spraying and dust suppression systems to meet environmental control requirements. Outdoor water tanks, as the core water storage component of the water spraying and dust suppression system, directly determine the continuous operation capability of the system. To adapt to the low-temperature operating environment of northern ports in winter, existing mobile port machinery water tanks generally use built-in heating rods to heat and prevent freezing of the water inside, thus avoiding the shutdown of the water spraying system due to water freezing.

[0003] In practical applications, existing water tanks with built-in heating rods have the heating rods directly submerged in the water. During port machinery movement, the water inside the tank churns, and sludge and impurities deposited at the bottom easily adhere to the surface of the heating rods, causing scaling, corrosion, and damage, significantly shortening the equipment's lifespan and reducing heating efficiency. Furthermore, if the heating rods need repair or replacement, the water in the tank must be completely emptied. Since the water tanks of mobile port machinery typically have a volume of over 10 cubic meters, emptying the tank is time-consuming and labor-intensive, significantly increasing the difficulty of maintenance and causing interruptions to port loading and unloading operations, severely impacting operational continuity. During daily use, when the water level in the tank drops below the heating rods, the heating rods may dry-burn, easily leading to short circuits, fires, and other safety accidents, posing a serious safety hazard.

[0008] In one feasible implementation, the mobile port machinery outdoor water storage tank further includes: The water inlet is located on the side of the tank, near one corner of the tank, and is connected to the water tank. The shape of the water inlet is matched with that of the water tank.

[0009] In one feasible implementation, the mobile port machinery outdoor water storage tank further includes: The drain pipe has its first end connected to the bottom of the box, and its second end extends horizontally. The second butterfly valve has its input end connected to the second end of the drain pipe. The drain pipe is connected to the output end of the second butterfly valve.

[0010] In one feasible implementation, the mobile port machinery outdoor water storage tank further includes: The protective cover is installed inside the box and is connected to the inner side wall of the box. The protective cover and the box form a protective cavity. There is a gap between the highest point of the protective cover and the inner top wall of the box. A level gauge is installed on the tank, with its detection end extending into the protective cavity to detect the liquid level inside the tank.

[0011] In one feasible implementation, the mobile port machinery outdoor water storage tank further includes: The water outlet bend is located at the bottom of the tank. The inlet end of the water outlet bend is inside the tank, and the outlet end of the water outlet bend extends out of the tank from the side of the tank. Mud cap, the mud cap is set above the inlet end of the outlet bend; The water outlet pipe has its first end connected to the output end of the water outlet bend, and its second end extends horizontally. The filter is located outside the housing, and its output end is connected to the second end of the water outlet pipe.

[0012] In one feasible implementation, the mobile port machinery outdoor water storage tank further includes: The first butterfly valve has its input end connected to the second end of the outlet pipe and its output end connected to the input end of the filter.

[0013] In one feasible implementation, the mobile port machinery outdoor water storage tank further includes: The partition is installed inside the container along the length perpendicular to the container body. The partition is connected to the inner side wall of the container body and divides the container body into two symmetrical compartments. There is a gap between the highest point of the partition and the inner wall of the top surface of the container, and a gap between the lowest point of the partition and the inner wall of the bottom surface of the container, so that the two compartments are connected.

[0015] The mobile port machinery outdoor water storage tank of this application has the following advantages compared with the prior art: The mobile port machinery outdoor water storage tank provided in this application fundamentally solves the core pain points of existing mobile port machinery water storage tanks—such as heater damage, easy dry burning, and high maintenance difficulty—through the coordinated operation of the tank body, heater, heating sleeve, buffer tank, and shut-off valve. Specifically, since the heater is usually located at the bottom of the tank, this application completely isolates the heater from the water and sediment inside the tank by installing a heating sleeve that penetrates the tank body. This prevents scale and corrosion caused by sludge and impurities carried by the surging water inside the tank adhering to the heater surface during port machinery movement, significantly extending the heater's service life, improving the long-term stability of heating efficiency, and reducing the frequency of heater maintenance and replacement. The buffer tank is not sealed; by connecting the heating sleeve to the buffer tank, water inside the tank can continuously enter the heating sleeve through the opening in the buffer tank. Even when the tank body is emptied, the water in the buffer tank can still be supplied with heating. By maintaining a stable water body and ensuring that the heating jacket is always filled with water, the heater is protected against dry burning from a mechanical structure perspective, fundamentally eliminating safety hazards such as short circuits and fires caused by dry burning. Furthermore, by installing a shut-off valve between the heating jacket and the buffer tank, the connection between the heating jacket and the buffer tank can be independently controlled. When the heater is under maintenance or replaced, only the shut-off valve needs to be closed to completely isolate the heating jacket from the water in the tank, without having to drain the large volume of water in the tank. This greatly simplifies the maintenance operation process, shortens downtime for maintenance, and ensures the continuity of port loading and unloading operations, thus better adapting to the working conditions of continuous outdoor operations of mobile port machinery.

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] like Figures 1 to 4 As shown in the embodiment of this application, a mobile port machinery outdoor water storage tank is proposed, comprising: a tank body 11, a heater 12, a heating sleeve 13, a buffer tank 14, and a shut-off valve 15; the first end of the heater 12 protrudes outside the tank body 11, and the second end of the heater 12 extends into the tank body 11; the heating sleeve 13 is fitted over the heater 12, and both ends of the heating sleeve 13 penetrate two opposite side walls of the tank body 11 respectively, with the first end of the heating sleeve 13 sealed to the first end of the heater 12; the buffer tank 14 is disposed inside the tank body 11, and the buffer tank 14 is connected to the second end of the heating sleeve 13, with an opening at the top of the buffer tank 14, through which water in the tank body 11 enters the heating sleeve 13; the input end of the shut-off valve 15 is connected to the buffer tank 14, and the output end of the shut-off valve 15 is connected to the heating sleeve 13, so as to control the communication state between the heating sleeve 13 and the buffer tank 14 through the shut-off valve 15.

[0022] The mobile port machinery outdoor water storage tank provided in this application, through the coordinated operation of the tank body 11, heater 12, heating sleeve 13, buffer tank 14, and shut-off valve 15, fundamentally solves the core pain points of existing mobile port machinery water storage tanks, such as heater damage, easy dry burning, and high maintenance difficulty. Specifically, since the heater 12 is usually located at the bottom inside the tank body 11, this application completely isolates the heater 12 from the water and sediment inside the tank by fitting a heating sleeve 13 through the tank body 11 outside the heater 12. This avoids scaling and corrosion caused by the surging water inside the tank carrying sludge and impurities adhering to the surface of the heater 12 during the port machinery's movement, significantly extending the service life of the heater 12, improving the long-term stability of heating efficiency, and reducing the frequency of maintenance and replacement of the heater 12. The buffer tank 14 is not sealed. By connecting the heating sleeve 13 to the buffer tank 14, water from the tank body 11 can continuously enter the heating sleeve 13 through the opening in the buffer tank 14. Even when the tank body 11 is emptied, the buffer tank... A stable body of water can still be retained inside the heating sleeve 13, ensuring that the heating sleeve 13 is always full of water. This provides anti-dry-burn protection for the heater 12 from a mechanical structure perspective, fundamentally eliminating safety hazards such as short circuits and fires caused by dry burning of the heater 12. Furthermore, by installing a shut-off valve 15 between the heating sleeve 13 and the buffer tank 14, the connection between the heating sleeve 13 and the buffer tank 14 can be independently controlled. When the heater 12 is being repaired or replaced, only the shut-off valve 15 needs to be closed to completely isolate the heating sleeve 13 from the water in the tank. There is no need to drain the large volume of water in the tank, which greatly simplifies the maintenance operation process, shortens the downtime for maintenance, and ensures the continuity of port loading and unloading operations, thus better adapting to the working conditions of continuous outdoor operations of mobile port machinery.

[0023] Furthermore, the tank 11 is mounted on the base 16 to increase the load-bearing capacity of the bottom surface of the tank 11, thereby adapting to the load-bearing requirements of large-volume water bodies.

[0024] Furthermore, the buffer box bracket 17 is located below the buffer box 14 and is connected to the bottom surface of the box 11 to support the buffer box 14 and ensure the installation stability of the buffer box 14 inside the box 11.

[0025] Understandably, the heater 12 has a built-in temperature sensor, which can detect the temperature to control the working state of the heater 12 so as to automatically heat the water under low temperature conditions.

[0026] like Figures 1 to 4As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: a connecting elbow 18, an outlet pipe 19, an internal threaded connector 20, and a sleeve support 21; the connecting elbow 18 is disposed outside the tank body 11, and the first end of the connecting elbow 18 is connected to the second end of the heating sleeve 13; the first end of the outlet pipe 19 is connected to the second end of the connecting elbow 18, the second end of the outlet pipe 19 extends into the tank body 11, and the second end of the outlet pipe 19 is connected to the bottom surface of the buffer tank 14; the internal threaded connector 20 is disposed at the first end of the heater 12, and the internal threaded connector 20 is sealed to the first end of the heating sleeve 13; the sleeve support 21 is disposed below the heating sleeve 13, and the sleeve support 21 is connected to the inner wall of the tank body 11.

[0027] In this technical solution, by setting an external connecting elbow 18 and an outlet pipe 19 extending into the housing 11, the heating sleeve 13 and the buffer tank 14 are sealed and connected inside the housing 11. This places the pipeline connection point outside the housing 11, reducing the risk of water leakage into the heating sleeve 13 and facilitating subsequent inspection and maintenance of the pipeline sealing points. By installing an internal threaded connector 20, the end of the heater 12 is sealed to the heating sleeve 13, ensuring the airtightness of the inner cavity of the heating sleeve 13. To prevent water leakage from affecting the electrical safety of heater 12, and to enable quick installation and disassembly of heater 12, the difficulty of disassembly and maintenance of heater 12 is further reduced; by setting a sleeve support 21 connected to the inner wall of housing 11 below heating sleeve 13, a stable support is formed for heating sleeve 13, avoiding deformation and weld cracking of heating sleeve 13 caused by long-term movement and vibration of port machinery, improving the structural stability and service life of heating sleeve 13, and further adapting to the high-frequency movement and vibration outdoor operation conditions of mobile port machinery.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: an insulation layer 22, a fixing stud 23, a washer 24, and a nut 25; the insulation layer 22 is disposed on the outside of the tank body 11; the fixing stud is vertically disposed on the outer wall of the tank body 11, and the fixing stud passes through the insulation layer 22; the washer 24 is fitted over the fixing stud, and the washer 24 is in contact with the side of the insulation layer 22 away from the tank body 11; the nut 25 presses the washer 24 tightly against the outside of the insulation layer 22.

[0029] In this technical solution, by covering the outside of the tank 11 with an insulation layer 22, heat loss of the water inside the tank is reduced. This, combined with the heater 12, prevents the water from freezing in low-temperature environments, ensuring the continuous operation of the port sprinkler system in northern winters. This reduces the likelihood of water freezing and sprinkler system shutdowns in winter. The insulation layer 22 is detachably installed on the outside of the tank 11 by using the fixing studs 23, washers 24, and nuts 25. This not only makes installation convenient and secure but also allows for repeated disassembly and reuse, avoiding damage and detachment of the insulation layer 22 caused by long-term outdoor use. This ensures long-term stability of the insulation performance, significantly reduces the maintenance and replacement costs of the insulation layer 22 structure, avoids the problems of easy damage to the insulation layer 22 and continuous degradation of its low-temperature adaptability, and further enhances the adaptability of the water storage tank to the extreme low-temperature outdoor environment of northern ports.

[0030] In some examples, the insulation layer 22 covers the four sides of the enclosure 11 except for the bottom and top surfaces. The insulation layer 22 is made of stainless steel sheet as the surface layer and combined with the insulation core layer material.

[0031] In some examples, the housing 11 is made of stainless steel sheet to prevent rust damage.

[0032] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: a water inlet 26; the water inlet 26 is located on the side of the tank body 11, near one corner of the tank body 11, and the water inlet 26 is connected to the water tank; wherein, the shape of the water inlet 26 is adapted to the shape of the water tank.

[0033] In this technical solution, an inlet 26 adapted to the shape of the water tank is set at one corner near the top on the side of the tank 11, so that the inlet 26 can be directly connected to the water tank, maximizing the water intake speed, improving the efficiency of water supply operation, and improving the firmness between the inlet 26 and the water tank. This prevents the connection between the port machinery and the water tank from becoming loose or disconnected during port machinery movement or water supply, thus avoiding water spillage and ensuring the stability of water supply operation. It also meets the docking requirements of the automatic water supply system of port machinery, further improving the operational adaptability of the water storage tank and ensuring the continuity of water supply for the sprinkler system.

[0034] In some examples, a fixing frame 27 is installed on the outside of the water inlet 26, and fasteners are provided at the four corners of the fixing frame 27 to fix the water tank to the water inlet 26 and prevent it from falling off.

[0035] Furthermore, an overflow pipe 28 is installed at the top of the tank 11 to promptly discharge excess water when the water level in the tank 11 exceeds the upper limit, thereby ensuring the safe operation of the water storage tank.

[0036] like Figure 1 , Figure 2 and Figure 6As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: a drain pipe 29, a second butterfly valve 30, and a drain outlet 31; the first end of the drain pipe 29 is connected to the bottom surface of the tank body 11, and the second end of the drain pipe 29 extends horizontally; the input end of the second butterfly valve 30 is connected to the second end of the drain pipe 29; and the drain outlet 31 is connected to the output end of the second butterfly valve 30.

[0037] In this technical solution, a drain pipe 29 connected to the bottom of the tank 11 is installed, along with a second butterfly valve 30 and a drain outlet 31, to achieve controlled drainage of water inside the tank. This prevents water overflow at the port operation site and facilitates regular cleaning and maintenance of the tank 11, meeting the environmental protection requirements of the port site. The drain pipe 29 is a bend, and its output end extends horizontally to allow for the connection of a flexible hose, facilitating the collection of discharged residual water. Furthermore, by centrally locating the drainage control points on the outside of the tank 11, operation is convenient, and drainage can be completed without entering the tank 11. This significantly reduces the difficulty of cleaning and maintaining the water storage tank, improves the convenience of equipment operation and maintenance, and meets the daily operation and maintenance management needs of port equipment.

[0038] like Figure 7 and Figure 8 As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: a protective cover 32 and a level gauge 33; the protective cover 32 is disposed inside the tank body 11, the protective cover 32 is connected to the inner side wall of the tank body 11, the protective cover 32 and the tank body 11 enclose a protective cavity, and there is a gap between the highest point of the protective cover 32 and the inner top wall of the tank body 11; the level gauge 33 is disposed on the tank body 11, and the detection end of the level gauge 33 extends into the protective cavity to detect the liquid level inside the tank body 11.

[0039] In this technical solution, a protective cover 32 is installed inside the tank 11, and the detection end of the level gauge 33 is placed inside the protective cavity. The protective cover 32 isolates the detection area of ​​the level gauge 33 from the water body with large fluctuations inside the tank. At the same time, the gap between the top of the protective cover 32 and the inner wall of the top surface of the tank 11, and the gap between the bottom of the protective cover 32 and the inner wall of the bottom surface of the tank 11, ensure that the water level in the protective cavity is synchronized with the actual water level inside the tank 11 in real time. This reduces the interference of large fluctuations in the water surface during the start-up, shutdown, and movement of the port machinery on the detection results of the level gauge 33, avoids malfunctions such as dry burning of the heater 12 and dry running of the water pump caused by false alarms of high and low water levels, improves the accuracy and stability of water level detection, ensures the reliable operation of the automated control system of the water storage tank, reduces the impact of water surface fluctuations on the level gauge 33, improves the detection accuracy of the level gauge 33 under various working conditions, and further adapts to the control requirements of automated continuous operation of the port.

[0040] like Figure 9 and Figure 10As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: an outlet bend 34, a mud cap 35, an outlet pipe 36, and a filter 37; the outlet bend 34 is located at the bottom of the tank body 11, with its input end inside the tank body 11 and its output end extending out of the tank body 11 from the side; the mud cap 35 is located above the input end of the outlet bend 34; the first end of the outlet pipe 36 is connected to the output end of the outlet bend 34, and the second end of the outlet pipe 36 extends horizontally; the filter 37 is located outside the tank body 11, and its output end is connected to the second end of the outlet pipe 36.

[0041] In this technical solution, the inlet end of the water outlet bend 34 is set upwards, and a mud cap 35 is installed above the inlet end of the water outlet bend 34. This structurally reduces the amount of sludge and impurities deposited at the bottom of the tank 11 being sucked into the water supply pipeline, thereby reducing the problem of bottom-outlet pipelines being prone to bottom-suction blockage from the source. By installing a filter 37 at the end of the water outlet pipeline 36 outside the tank 11, the water delivered to the sprinkler system is filtered a second time, forming a double anti-clogging protection, further reducing the blockage problem of pipelines and sprinkler heads, enabling the port sprinkler dust suppression system to operate more stably for a longer period of time, in order to meet the needs of continuous port environmental protection operations, especially suitable for the working conditions of water surging and impurities being easily stirred up during the movement of mobile port machinery.

[0042] It should be noted that the part of the water outlet bend 34 inside the tank 11 is a U-shaped bend. The inlet end of the water outlet bend 34 is higher than the height of the sediment at the bottom of the tank 11 to prevent the sediment at the bottom of the tank 11 from being sucked into the sprinkler pipe and causing blockage.

[0043] like Figure 9 As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: a first butterfly valve 38 and a centrifugal pump 39; the input end of the first butterfly valve 38 is connected to the second end of the outlet pipe 36, and the output end of the first butterfly valve 38 is connected to the input end of the filter 37; the input end of the centrifugal pump 39 is connected to the output end of the filter 37, and the output end of the centrifugal pump 39 extends horizontally.

[0044] In this technical solution, by setting a first butterfly valve 38 between the water outlet pipe 36 and the filter 37, the water supply to the tank 11 side can be manually cut off, which facilitates the maintenance and replacement of the filter 37 and the centrifugal pump 39. The operation and maintenance can be completed without emptying the water in the tank, which further reduces the maintenance difficulty of the sprinkler water supply system. The centrifugal pump 39 provides a stable pressurized water supply to the sprinkler system, which can accurately control the sprinkler pressure and flow rate, adjust the sprinkler dust suppression effect, and adapt to the dust suppression needs of different operation scenarios.

[0045] In some examples, a control box 40 is mounted on the outside of the housing 11. The control box 40 is used to integrate local / remote control elements of the electrical components of the water storage tank to facilitate automated control of the water storage tank.

[0046] In some examples, the control elements of the centrifugal pump 39 and heater 12, as well as the temperature sensor and level gauge 33, are connected to the control box 40 to realize local and remote controllable water supply and real-time monitoring of the water level and temperature of the tank 11. The control box 40 can be easily connected to the port's automatic sprinkler or water supply system to adapt to the control requirements of port automation operations.

[0047] like Figure 10 As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: a partition 41 and an inner frame 42; the partition 41 is disposed inside the tank 11 along a length direction perpendicular to the tank body 11, the partition 41 is connected to the inner side wall of the tank body 11, and the partition 41 divides the inside of the tank body 11 into two symmetrical compartments; there is a gap between the highest point of the partition 41 and the inner top wall of the tank body 11, and there is a gap between the lowest point of the partition 41 and the inner bottom wall of the tank body 11, so that the two compartments are connected; the inner frame 42 is disposed on the inner side of the tank body 11 along the circumference of the tank body 11, and the inner frame 42 is connected to the inner side wall of the tank body 11.

[0048] In this technical solution, a vertical partition 41 is installed inside the container 11, dividing the interior of the container 11 into two interconnected symmetrical compartments. The partition 41 acts as a buffer for the water sloshing during the start-up, shutdown, and speed change of the port machinery, reducing the impact of the water sloshing and avoiding problems such as weld cracking and structural deformation of the container 11 caused by long-term impact. The water passage gaps reserved above and below the partition 41 ensure that the water in the two compartments is connected in real time, without affecting the normal water storage and supply functions of the container 11. An inner frame 42 is installed circumferentially inside the container 11 to provide stable internal support for the container 11, further improving the structural strength and deformation resistance of the container 11, and extending the structural service life of the container 11, thus making it more adaptable to the operating conditions of frequent start-up, shutdown, and speed change of the mobile port machinery.

[0049] Furthermore, the gap between the partition 41 and the bottom surface of the housing 11 is greater than the diameter of the heating sleeve 13, so that the heating sleeve 13 does not interfere with the partition 41.

[0050] In some examples, the inner frame 42 includes three horizontal frames and one vertical frame. The horizontal frames are located at the bottom, middle and top of the box 11, and the vertical frame is located at the position of the partition 41. The inner frame 42 is welded and fixed to the inner wall of the box 11 to provide internal support for the box 11.

[0051] like Figure 1 , Figure 2 , Figure 7 and Figure 10 As shown, in one feasible embodiment, the mobile port machinery outdoor water storage tank further includes: a manhole 43, an external ladder 44, and an internal ladder 45; the manhole 43 is located on the top surface of the tank body 11, and the manhole 43 corresponds to a compartment; the external ladder 44 is located on the outer side wall of the tank body 11 along the height direction of the tank body 11, and the external ladder 44 corresponds to a compartment; the internal ladder 45 is located on the inner side wall of the tank body 11 along the height direction of the tank body 11, and the internal ladder 45 is opposite to the external ladder 44, and the internal ladder 45 corresponds to the external ladder 44.

[0052] In this technical solution, by setting manholes 43 on the top surface of the container 11 that correspond one-to-one with the compartments, and in conjunction with the external ladders 44 on the outer wall of the container 11 and the internal ladders 45 on the inner wall of the container 11, convenient access channels are provided for maintenance personnel. This allows maintenance personnel to quickly enter the various compartments inside the container 11 to carry out cleaning, maintenance, and repair work, greatly improving the convenience and safety of internal equipment operation and maintenance. The one-to-one correspondence between the manholes 43 and the compartments enables independent maintenance of two compartments, further enhancing the flexibility of operation and maintenance and meeting the daily operation and maintenance management needs of port equipment.

[0053] In some examples, the manhole 43 is provided with an edge that protrudes outward from the housing 11 to facilitate a seal with the manhole cover 46, creating a relatively sealed environment for the housing 11 and preventing the water inside the housing from being contaminated.

[0054] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0055] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
