Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically an automatic tilting cleaning device for chemical energy storage devices. Background Technology

[0002] Chemical energy storage essentially utilizes the chemical reaction that occurs when energy storage materials come into contact, storing energy through the conversion of thermal and chemical energy, and then releasing the energy through a chemical reaction when needed. A prior patent, an electrically heated calcium hydroxide chemical energy storage device and system (application number: 2023117898976), has a reactor internal operating temperature that can reach up to 850℃, thus requiring extremely high sealing performance. Leaks would not only affect normal operation but also pose safety risks. Furthermore, the device experiences significant temperature variations, leading to thermal expansion and contraction of components. Therefore, to minimize leakage risks, the energy storage device was designed with only one detachable surface, sealed with high-temperature resistant gaskets and high-strength bolts. However, in practical applications, the reactant calcium oxide undergoes thermal decomposition or thermal cross-linking (thermo-oxidative aging) after multiple energy storage cycles, necessitating replacement with new reactants. The device is large and heavy, and the only detachable surface faces upwards, requiring multiple lifting operations for material replacement. Furthermore, laying down or inverting the energy storage equipment requires custom-made cleaning supports, which is not only difficult to operate and time-consuming, but also poses a greater risk of safety hazards. Additionally, the thermal and oxidative aging of reactants and repeated reactions result in residues adhering to the equipment's heat dissipation fins. Moreover, the reactor's internal structure has too many and too small interlayers, making manual cleaning of residual reactants extremely difficult. Therefore, designing a safe, fast, and efficient automated device for automatically flipping and cleaning chemical energy storage equipment is urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide an automatic tilting and cleaning device for chemical energy storage devices. This cleaning device can automatically tilt the chemical energy storage devices, and is highly efficient and has a high cleaning rate.

[0004] The technical solution of this utility model:

[0005] An automatic tilting and cleaning device for a chemical energy storage device includes a rotating wheel mechanism, an automatic water spraying and aerosol spraying mechanism, a dirt collection box, and a PLC control cabinet. The rotating wheel mechanism includes a rotating wheel fixing frame, two rotating wheels, an energy storage device fixing frame, and an adjustable connecting frame. Each end of the rotating wheel fixing frame has a rotating wheel that can rotate relative to the fixing frame. The energy storage device fixing frame is fixedly installed between the two rotating wheels. The adjustable connecting frame is mounted on the energy storage device fixing frame, and the dirt collection box is placed below the fixing frame. An automatic water spraying and aerosol spraying mechanism is installed between the energy storage device fixing frame and the dirt collection box. The PLC control cabinet controls the rotation of the rotating wheels and controls the automatic water spraying and aerosol spraying mechanism to perform water spraying and aerosol spraying.

[0006] The beneficial effects of this utility model are:

[0007] 1. This application utilizes a rotating wheel mechanism to achieve automatic rotation and flipping of the chemical energy storage device, which facilitates the replacement of reactants and makes it easier to clean reactant residues in the packing gaps inside the chemical energy storage device. This automatic flipping function is safer and more efficient than the original operation method (the overhead crane lays down the chemical energy storage device, and then it is inverted and lifted onto the customized cleaning bracket).

[0008] 2. The automatic tilting and cleaning equipment for chemical energy storage devices of this application has a compact structure. The rotating wheel structure is equipped with a channel steel frame, and the connecting parts can be adapted according to the size of the chemical energy storage device to be cleaned. It has high versatility and can realize the automatic rotation and tilting of chemical energy storage devices with dimensions within 1900mm in width, 2500mm in length, and 1700mm in height.

[0009] 3. The automatic tilting and cleaning equipment for chemical energy storage devices in this application can tilt the chemical energy storage device 180 degrees so that the only sealing surface faces downwards. The automatic water spraying and air jetting mechanism of the automatic tilting and cleaning equipment for chemical energy storage devices is equipped with high-pressure water spraying nozzles and high-pressure air jetting nozzles to clean the residual reactants in the gaps of the material structure inside the chemical energy storage device with high-pressure water spraying and high-pressure air jetting to dry them. Compared with the original cleaning method (the chemical energy storage device is inverted and suspended with the sealing surface facing downwards, placed on a customized equipment cleaning frame, and a person wearing protective equipment crawls into the bottom of the chemical energy storage device to manually rinse, wash, and dry it), the efficiency is greatly improved, the safety is guaranteed, the fault tolerance rate is higher, and there is no need to customize the equipment cleaning frame and manpower required for cleaning, thus ensuring economic efficiency.

[0010] 4. The automatic water and air spray mechanism of the automatic tilting and cleaning equipment for chemical energy storage devices in this application is equipped with two electric linear guide rails. Controlled by a PLC, these two rails move along the X and Y axes, carrying high-pressure air nozzles and high-pressure water nozzles, achieving comprehensive high-pressure rinsing and drying of all the numerous reactant storage tanks inside the chemical energy storage device. This significantly improves efficiency and enhances the rinsing and drying effects compared to the original manual cleaning method of manually rinsing each storage tank.

[0011] 5. The automatic tilting and cleaning equipment for chemical energy storage devices in this application is equipped with a manual rotation mechanism. It utilizes a limit rotation gear that meshes with the gear of the rotation mechanism, and designs a rotating shaft and a manual rotation handle. In the event of equipment failure or power outage or other unexpected situations, the rotating wheel mechanism can be manually rotated. This is a redundant design that improves the fault tolerance of the entire equipment.

[0012] 6. The automatic tilting and cleaning equipment for the chemical energy storage device of this application is equipped with a dirt collection mechanism at the bottom. During high-pressure water jetting and air spraying, residual reactants and residues will be washed away. Two dirt collection boxes are provided below to receive the washed-away reactants and residues. The dirt collection boxes are equipped with linear slide rails to fix the equipment base frame, which facilitates manual pulling and cleaning of the dirt collection boxes, making the workshop cleaner and improving the working environment.

[0022] In order to solve the problems in the background technology, an automated equipment is invented that performs fully automatic cleaning of chemical energy storage devices for reactants such as electrically heated calcium hydroxide, and has automatic flipping function and automatic high-pressure jet water spraying function.

[0023] In the following detailed description, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] This application discloses an automatic tilting and cleaning device for chemical energy storage devices, comprising a rotating wheel mechanism, a PLC control cabinet, a high-torque motor and reducer, an automatic water and air spray mechanism, a manual rotating mechanism, a dirt collection box, and a base frame. This device effectively solves the main problems of current tilting and cleaning methods for chemical energy storage devices, and is a modern device with higher efficiency, wider applicability, higher automation, stronger cleaning ability, and greater safety.

[0026] like Figure 1 , 2As shown, this application discloses an automatic tilting and cleaning device for a chemical energy storage device, comprising a rotating wheel mechanism 1, an automatic water spraying and aerosol spraying mechanism 2, a dirt collection box 3, and a PLC control cabinet 4. The rotating wheel mechanism 1 includes a rotating wheel fixing frame 11, two rotating wheels 12, an energy storage device fixing frame 13, and an adjustable connecting frame 14. Each end of the rotating wheel fixing frame is equipped with a rotating wheel, which can rotate relative to the fixing frame. The energy storage device fixing frame is fixed between the two rotating wheels. The adjustable connecting frame is mounted on the energy storage device fixing frame for fixing the chemical energy storage device. A dirt collection box is placed below the energy storage device fixing frame to collect dirt flowing down from the cleaning chemical energy storage device 7. An automatic water spraying and aerosol spraying mechanism is mounted below the energy storage device fixing frame. The PLC control cabinet controls the rotation of the rotating wheels and controls the automatic water spraying and aerosol spraying mechanism to perform water spraying and aerosol spraying. Two sets of adjustable connecting frames are respectively fixed to the upper and lower ends of the rotating wheel fixing frame for fixing the chemical energy storage device. The rotating wheel of the described rotating wheel mechanism can be mounted on a rotating wheel fixing frame via a shaft, bearing, and bearing seat. The shaft is connected to the motor via a coupling. In this application, the rotating wheel is driven by a high-torque motor 16 and a reducer via a coupling 15. The high-torque motor has an automatic locking function, which can automatically lock when needed to prevent the rotating wheel from rotating. The PLC control cabinet controls the high-torque motor, thereby driving the rotating wheel to rotate.

[0027] Figure 3 , 4 As shown, the cleaning equipment also includes a base frame 5, on which the rotating wheel mechanism, automatic water spraying and aerodynamic mechanism, dirt collection box, and PLC control cabinet are mounted. The rotating wheel mechanism, automatic water spraying and aerodynamic mechanism, and PLC control cabinet are fixed to the base frame, and the dirt collection box can preferably slide back and forth on the base frame.

[0028] like Figure 3 , 4 As shown, the equipment base is equipped with a linear slide rail 51, and the dirt collection box is placed on the linear slide rail and bolted to the slider 52. The linear slide rail on the base facilitates the placement and removal of the dirt collection box.

[0029] like Figure 3As shown, the cleaning equipment also includes a manual rotation mechanism 6, which is fixed to the base frame. The manual rotation mechanism 6 includes a rotating shaft 61, a handle 62, bearing seats 63, bearings 64, and a limiting rotation gear 65. Each of the two rotating wheels has one or two bearing seats at corresponding positions below it, i.e., two pairs of bearing seats are provided below the two rotating wheels. The bearing seats are fixed to the base frame. A limiting rotation gear is installed inside each bearing seat, and a bearing is installed inside each limiting rotation gear. The rotating shaft is installed in the bearings of the two corresponding bearing seats. A handle is attached to one end of the rotating shaft, and a locking pin is provided on the handle. The locking pin passes through the handle, and the other end is inserted into the base. When the rotating wheel mechanism is working normally or when it is necessary to lock the manual rotation mechanism, the manual rotation mechanism is locked in place by the locking pin. When the rotating wheel mechanism cannot be used, the locking pin is removed, and the rotating wheel is manually driven to rotate. The limiting rotation gear is located below the rotating wheel and meshes with it. Adding a manual rotation mechanism allows for manual rotation of the rotating wheel mechanism in case of equipment malfunction or unexpected situations such as power outages. The limiting rotating wheel inside the bearing housing is located directly below the rotating wheel or on the side directly below the rotating wheel.

[0030] like Figure 5 As shown, the automatic water spraying and jetting mechanism 2 includes an electric slide rail fixing frame 21, a Y-axis electric slide rail 22 mounted on the electric slide rail fixing frame, an X-axis electric slide rail 23 mounted on a fixing block on the Y-axis electric slide rail, a nozzle fixing frame 24 mounted on the X-axis electric slide rail, and a high-pressure jet nozzle 25 and a high-pressure water spray nozzle 26 mounted on the nozzle fixing frame.

[0031] The X-axis and Y-axis electric slide rails adopt a commonly used split structure in existing technology, or they can adopt a combined form in existing technology, such as a two-rail electric slide rail or an XY orthogonal manipulator. The high-pressure jet nozzle is connected to a high-pressure air source through an air pipe; the high-pressure water nozzle is connected to a water pump through a water pipe.

[0032] Work process:

[0033] Step 1: Install the adapted adjustable lower connecting bracket onto the energy storage equipment mounting frame using bolts. Lock the high-torque motor controlled by the PLC and also lock the manual rotation mechanism for double safety. Then, hoist the chemical energy storage equipment body onto the mounting frame. Figure 6 First, use bolts to connect the chemical energy storage device body to the lower adjustable connecting frame. Next, use bolts to connect the upper adjustable connecting frame to the chemical energy storage device body and the upper energy storage device fixing frame, thus completing the installation of the chemical energy storage device body.

[0034] Step 2: Then, release the locking pin of the manual rotation mechanism to unlock it. The PLC outputs a signal to the high-torque motor and reducer to start rotating at low speed until the chemical energy storage device body rotates 180 degrees with the sealing surface facing down. At this time, some reactants will fall out of the chemical energy storage device body. After the rotation is completed, pull out the dirt collection box and clean up the scattered reactants.

[0035] Step 3: After cleaning the dirt collection box, push it back into its original position and control the PLC to start the cleaning process. The PLC controls the water pump outside the system to start high-pressure flushing, and controls the X-axis and Y-axis electric slide rails to carry the high-pressure water nozzles to flush the numerous storage tanks inside the chemical energy storage device body without leaving any residue.

[0036] Step 4: After rinsing, remove the flushed reactants and wastewater from the dirt collection box for cleaning.

[0037] Step 5: After cleaning and returning the dirt collection box to its place, the high-pressure gas drying process begins. The solenoid valve in the PLC control cabinet is opened, and high-pressure gas is blown into the storage tank inside the chemical energy storage device through the high-pressure nozzle. Similarly, the X-axis and Y-axis electric slide rails are controlled by the programmed travel route to carry the high-pressure nozzle for a complete and thorough drying operation.

[0038] Step Six: After the drying process is completed, check the rinsing and drying effects to complete the cleaning of the chemical energy storage device.

[0039] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art, inspired by this description, design similar structures and implementations to the above embodiments without departing from the technical essence of the present invention, such designs should fall within the protection scope of the present invention.
