Description

Technical Field

[0001] The present invention relates to the field of vegetable cleaning workshop equipment and systems, and in particular to dehydration equipment and a control system used in vegetable cleaning workshops. Background Art

[0002] In the field of vegetable processing, dehydration equipment is a key component in the pretreatment process. Its operational stability and control precision directly impact dehydration efficiency and finished product quality. Traditional dehydration equipment generally uses a rigid support structure. The mechanical vibration generated during operation is directly transmitted to the base, which not only increases noise pollution but also causes loose components and accelerated wear due to long-term vibration. Furthermore, the operating mode that relies on manual adjustment is difficult to adapt to the diverse material processing needs. There is room for improvement in operational convenience and dehydration consistency.

[0003] Existing dehydration equipment control systems often utilize a combination of discrete electrical components, lacking integrated control modules and safety protection mechanisms. When equipment operating parameters are abnormal or material distribution is uneven, traditional control systems are unable to provide immediate intervention, posing the risk of equipment downtime due to motor overload or uneven material loading. The control box's sealed structure is susceptible to moisture corrosion in the processing environment, and internal electrical components are prone to short circuits or poor contact. The startup logic only verifies basic power supply conditions and lacks comprehensive assessment of equipment safety status and material compatibility, resulting in frequent manual intervention and adjustments during batch operations. Furthermore, the single-cylinder design limits the processing capacity of a single batch, making it difficult to meet the needs of large-scale clean vegetable production. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present application provides a dehydration equipment and control system for a clean vegetable workshop to solve the problem that when the operating parameters of the above-mentioned equipment are abnormal or the material distribution is uneven, the traditional control system cannot achieve immediate intervention, and there is a risk of equipment shutdown due to motor overload or material overload; the control box sealing structure is easily corroded by moisture in the processing environment, and the internal electrical components are prone to short circuit or poor contact failure; the startup logic only checks the basic power supply conditions, and lacks comprehensive judgment on the equipment safety status and material adaptability, resulting in technical problems such as frequent manual intervention and adjustment during batch operations.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a dehydration device for a vegetable cleaning workshop, comprising a dehydration machine, a dehydration filter cartridge, a display module and a central control box module, wherein the dehydration filter cartridge is assembled in the inner cavity of the dehydration machine, and there are at least four groups of dehydration filter cartridges, the display module is assembled at the upper end of the dehydration machine, the central control box module is connected to the dehydration machine through a line, a load-bearing plate is provided at the bottom of the dehydration machine, a shock-absorbing module is provided at the bottom of the load-bearing plate, and the other end of the shock-absorbing module is connected to a base, by providing the shock-absorbing module, utilizing the elastic deformation of the internal damping rod thereof, it can effectively absorb the vibration generated by the dehydration machine during high-speed operation, reduce the impact of the equipment vibration on the workshop floor and surrounding equipment, and at the same time reduce the noise generated by the equipment due to vibration, thereby extending the service life of the equipment; the inner cavity of the central control box module is provided with a PLC control system module Block and drive circuit module, the PLC control system module is responsible for receiving and processing various signals, and accurately controlling the operation of the dehydration equipment through preset programs. The drive circuit module provides driving current for the motor and other components of the dehydration equipment according to the instructions of the PLC control system module to ensure that the equipment operates according to the set mode; the front ends of the external box door of the central control box module are respectively provided with proximity control switch and emergency stop switch module. The proximity control switch is used to sense the approach of the operator to realize convenient start and stop control of the equipment. The emergency stop switch module can immediately cut off the power supply of the equipment in an emergency to ensure the safety of personnel and equipment; the outside of the central control box module is connected to a one-way valve pipe, which can prevent external air or water vapor from backflowing into the central control box module to ensure a dry environment for internal electrical components. The front of the external box door of the central control box module is provided with a dehumidification module. A support mechanism is embedded in the front of the dehumidification module, which provides a firm support for the dehumidification module to ensure that it remains stable during operation. The back of the dehumidification module is connected to an assembly seat, which is used to assemble and connect the dehumidification module with the central control box module to ensure the tightness and stability of the connection. A second driving mechanism is provided on the back of the dehumidification module, which drives the air intake mechanism to work through operation, so that air can enter the dehumidification module for dehumidification treatment. The output end of the second driving mechanism is connected to the air intake mechanism, which is driven by the second driving mechanism to introduce humid air into the dehumidification module to provide power for air dehumidification. The inner cavity of the assembly seat is provided with an air drying and dehumidification mechanism, which uses the desiccant filled in its inner cavity to adsorb and dry the incoming humid air, effectively reducing the air humidity inside the central control box module and preventing electrical components from being damaged by moisture.

[0006] The dehydration filter cartridge is equipped with a first pulley at its bottom, a transmission belt mounted on its exterior, and a second pulley connected to the other end of the transmission belt's inner cavity. A first drive mechanism is mounted on top of the second pulley, connected to the inner cavity of the dehydration unit via a bracket. When the first drive mechanism is activated, it rotates the second pulley, transferring power to the first pulley via the transmission belt. This in turn causes the dehydration filter cartridge to rotate at high speed, using centrifugal force to remove moisture from the clean vegetables, achieving dehydration. This belt drive method features a simple structure, smooth transmission, low noise, and ease of maintenance and component replacement.

[0007] The outside of the dehydration filter cartridge is evenly provided with water filter holes, which can allow the water thrown out during the dehydration process to be smoothly discharged from the dehydration filter cartridge to achieve solid-liquid separation. The upper and lower ends of the outside of the dehydration filter cartridge are both sleeved with sealed bearings. On the one hand, the sealed bearings ensure that the dehydration filter cartridge can rotate flexibly, and on the other hand, they play a sealing role to prevent moisture and impurities from entering the interior of the dehydration body and affecting the normal operation of the equipment. The sealed bearings are arranged in the inner cavity of the dehydration body.

[0008] There are at least twelve groups of shock-absorbing modules, and a damping rod is provided inside the shock-absorbing module. The upper and lower ends of the damping rod are connected to the load-bearing plate and the base. Multiple groups of shock-absorbing modules work together to buffer and absorb the vibration of the dehydration equipment from multiple directions, thereby improving the shock-absorbing effect. A speed-regulating proximity switch module is provided on the top of the dehydration body. The speed-regulating proximity switch module can sense the operating status of the equipment and adjust the speed of the dehydration filter cartridge according to actual needs to adapt to the dehydration needs of different types and quantities of clean vegetables, thereby improving the dehydration efficiency and quality.

[0009] The central control box module has a slot on the front of its exterior door. An assembly frame is sleeved onto the exterior of the dehumidification module, connecting to the inner cavity of the slot. Magnets are installed on the ends of the dehumidification module opposite the slot, creating an attraction between the two sets of magnets. This assembly method makes the dehumidification module easier to install and remove. When the dehumidification module needs to be maintained or replaced, it can be easily removed by simply overcoming the attraction of the magnets. The magnets also ensure a secure connection during operation, preventing it from becoming loose.

[0010] The inner cavity of the air drying and dehumidifying mechanism is provided with a hollow groove, and the inner cavity of the hollow groove is filled with a desiccant. The desiccant can continuously absorb moisture in the humid air passing through the hollow groove to achieve the purpose of dehumidification. Exhaust holes are provided on the left and right sides of the hollow groove. The exhaust holes can allow the dry air after dehumidification treatment to be discharged smoothly, realize the circulation of air, and ensure the dehumidification effect.

[0011] The system comprises at least four PLC control system modules, each connected to four sets of dehydration filter cartridges via wiring. Each PLC control system module independently controls its corresponding filter cartridge, flexibly adjusting operating parameters based on the type, quantity, and dehydration requirements of the vegetables in each cartridge. This ensures precise dehydration, improving the equipment's intelligence and efficiency.

[0012] A dehydration control system for a vegetable cleaning workshop, based on the above-mentioned dehydration equipment for a vegetable cleaning workshop, includes a central control box, a PLC control system, four sets of drive circuits, an emergency stop switch, four sets of proximity switches and a dehumidification device; The central control box has at least four sets of independently operated PLC control system modules, corresponding to the closed-loop control of four sets of dehydration filter cartridges; The drive circuit module is electrically connected to the PLC control system module and is used to adjust the speed of the dehydration filter cartridge and the power of the dehumidification module; The proximity switch module and emergency stop switch module are used to detect the balance of material placement and trigger emergency stop respectively; The dehumidification device includes an air drying and dehumidification mechanism, the hollow groove of which is filled with silica gel desiccant, and a dual air duct circulation system (air intake mechanism + exhaust hole) is used to achieve closed-loop humidity control (target humidity range: leafy vegetables <8%RH, root vegetables <12%RH).

[0013] After receiving the trigger signal from the proximity switch, the PLC control system determines whether to start the dehydrator according to the following starting conditions: Basic electrical conditions: Check that the power supply voltage is within the range of AC220V±10% and the ground resistance is less than 4 ohms. Only when the power supply voltage is stable and the grounding is good can the equipment be started to ensure the normal operation of the equipment electrical system and avoid electrical failures and safety accidents caused by abnormal voltage or poor grounding. Equipment safety status: Confirm that the emergency stop switch is closed, the motor winding temperature is below 90°C, and the vibration amplitude does not exceed 0.5mm / s. A closed emergency stop switch indicates that the equipment is in normal standby mode, and the motor winding temperature and vibration amplitude are within the normal range, indicating that the equipment is not currently experiencing overheating or abnormal vibration issues. Ensure that the equipment is started in a safe state. System operating parameters and conditions: The preset dehydration mode matches the material type, the proximity switch signal is stable, and the material placement imbalance is less than 10%. This matching of the preset dehydration mode and material type allows the optimal dehydration method to be selected based on the characteristics of different clean vegetables, ensuring effective dehydration. A stable proximity switch signal indicates accurate material placement detection. A material placement imbalance of less than 10% prevents the dehydration filter cartridge from vibrating violently due to imbalance during high-speed rotation, which could affect equipment safety and dehydration efficiency.

[0014] The central control box is made of stainless steel and sealed, with an internal dehumidifier installed. It is wall-mounted on the workshop wall. Stainless steel is corrosion-resistant and strong. The sealing and internal dehumidifier effectively prevent external moisture, dust, and other particles from entering the central control box, protecting the internal electrical components. The wall-mounted installation saves workshop floor space and facilitates equipment layout and operation. The PLC control system is an integrated programmable logic controller that receives proximity switch signals and executes the centralized control and forward / reverse switching logic for the four dehydrators. The integrated programmable logic controller has high integration and reliability, and can quickly and accurately process proximity switch signals, enabling centralized control and forward / reverse switching of the four dehydrators, improving the equipment's automation control level and operational efficiency.

[0015] The drive circuit includes a contactor group for controlling the forward rotation, reverse rotation, and braking of the motor, which is electrically connected to the PLC output terminal. Under the control of the PLC output signal, the contactor group can realize the forward rotation, reverse rotation, and braking of the motor, thereby controlling the rotation direction and start and stop of the dehydration filter cartridge to meet the requirements of different dehydration processes. The proximity switch is installed at the corresponding position of each dehydrator to detect the presence of materials and send a trigger signal to the PLC. The proximity switch can accurately detect whether the material is in place and promptly feedback the signal to the PLC, ensuring that the dehydrator starts when the material is ready, avoiding idling and improving the rationality and efficiency of equipment operation. The central control box is made of stainless steel, sealed and equipped with a dehumidifier, and installed on the workshop wall. The stainless steel material, sealing treatment, and dehumidifier work together to create a good working environment for the electrical components inside the central control box, extend the service life of the electrical components, and ensure the stable operation of the dehydration control system.

[0016] In summary, the present application provides a dehydration device and control system for a vegetable cleaning workshop, which has the following beneficial effects: The dehydration equipment and control system used in the clean vegetable workshop can effectively reduce the vibration amplitude of the equipment during operation, reduce the noise and component loss caused by vibration, and improve the equipment operation stability and service life by setting a load-bearing plate and shock-absorbing module at the bottom of the dehydration body. The central control box module integrates the PLC control system module and the drive circuit module, which can realize automatic and precise control of the dehydration process. The display module can monitor the equipment status and parameters in real time, making it convenient for operators to preset the dehydration mode according to the material type and improve the dehydration efficiency and effect.

[0017] The dehydration equipment and control system used in the vegetable cleaning workshop, and the proximity control switch and emergency stop switch module installed on the outside of the central control box can quickly shut down the equipment in the event of an abnormality, enhancing operational safety; the cooperation of the one-way valve pipe and the dehumidification module, through the air drying and dehumidification mechanism and the air intake mechanism, can continuously dry the air in the control box, preventing moisture and dust from affecting the performance of electrical components, and ensuring the stable operation of precision components such as PLC.

[0018] The dehydration equipment and control system used in the clean vegetable workshop, in the dehydration control system, the PLC control system makes judgments based on multiple starting conditions, basic electrical conditions, equipment safety status and system operating parameter conditions, which can ensure that the equipment is started under the conditions of stable power supply voltage, good grounding, closed emergency stop switch, normal motor temperature and vibration amplitude, balanced material placement and mode matching, avoiding abnormal operation caused by electrical failure or material imbalance, which not only ensures equipment safety, but also makes the dehydration process more efficient and improves the quality consistency of clean vegetables after dehydration. The setting of four sets of dehydration filter cartridges can expand the equipment processing capacity to meet the batch production needs of the clean vegetable workshop.

A support mechanism 61 is embedded in the front of the dehumidification module 6, which provides a firm support for the dehumidification module 6 to ensure that it remains stable during operation. The back of the dehumidification module 6 is connected to an assembly seat 63, which is used to assemble and connect the dehumidification module 6 with the central control box module 4 to ensure the tightness and stability of the connection. A second driving mechanism 64 is provided on the back of the dehumidification module 6. The second driving mechanism 64 drives the air intake mechanism 65 to work through operation, so that air can enter the dehumidification module 6 for dehumidification treatment. The output end of the second driving mechanism 64 is connected to the air intake mechanism 65. Driven by the second driving mechanism 64, the air intake mechanism 65 introduces humid air into the dehumidification module 6 to provide power for air dehumidification. The inner cavity of the assembly seat 63 is provided with an air drying and dehumidification mechanism 66. The air drying and dehumidification mechanism 66 uses the desiccant filled in its inner cavity to adsorb and dry the incoming humid air, effectively reducing the air humidity inside the central control box module 4 and preventing electrical components from being damaged by moisture.

[0027] See also Figure 2The dehydration filter cartridge 2 is equipped with a first pulley 22 at its bottom. A transmission belt 24 is attached to the outside of the first pulley 22. A second pulley 23 is connected to the other end of the inner cavity of the transmission belt 24. A first drive mechanism 25 is installed on top of the second pulley 23. The first drive mechanism 25 is connected to the inner cavity of the dehydration body 1 via a bracket. When the first drive mechanism 25 is activated, it drives the second pulley 23 to rotate, transmitting power to the first pulley 22 via the transmission belt 24. This in turn causes the dehydration filter cartridge 2 to rotate at high speed, using centrifugal force to remove water from the clean vegetables, achieving the dehydration function. This belt drive method features a simple structure, smooth transmission, low noise, and is easy to maintain and replace components.

[0028] The outside of the dehydration filter cartridge 2 is evenly provided with water filter holes, which can allow the water thrown out during the dehydration process to be smoothly discharged from the dehydration filter cartridge 2 to achieve solid-liquid separation. The upper and lower ends of the outside of the dehydration filter cartridge 2 are both sleeved with sealed bearings 21. On the one hand, the sealed bearings 21 ensure that the dehydration filter cartridge 2 can rotate flexibly, and on the other hand, they play a sealing role to prevent moisture and impurities from entering the interior of the dehydration body 1 and affecting the normal operation of the equipment. The sealed bearings 21 are arranged in the inner cavity of the dehydration body 1.

[0029] There are at least twelve groups of shock-absorbing modules 13, and a damping rod is provided inside the shock-absorbing module 13. The upper and lower ends of the damping rod are connected to the load-bearing plate 12 and the base 14. Multiple groups of shock-absorbing modules 13 work together to buffer and absorb the vibration of the dehydration equipment from multiple directions, thereby improving the shock-absorbing effect. A speed-regulating proximity switch module 11 is provided on the top of the dehydration body 1. The speed-regulating proximity switch module 11 can sense the operating status of the equipment and adjust the rotation speed of the dehydration filter cartridge 2 according to actual needs to adapt to the dehydration needs of different types and quantities of clean vegetables, thereby improving the dehydration efficiency and quality.

[0030] See also Figure 3 The front of the central control box module 4's exterior door features a slot. An assembly frame 62 is sleeved onto the exterior of the dehumidification module 6, which connects to the inner cavity of the slot. Magnets are also installed on the opposite end of the dehumidification module 6 from the slot, creating an attraction between the two sets of magnets. This assembly method facilitates the installation and removal of the dehumidification module 6. When maintenance or replacement is required, the dehumidification module 6 can be easily removed by simply overcoming the magnets' attraction. The magnets' attraction also ensures that the dehumidification module 6 remains securely connected during operation, preventing it from becoming loose.

[0031] See also Figure 4 and Figure 5The inner cavity of the air drying and dehumidifying mechanism 66 is provided with a hollow groove, and the inner cavity of the hollow groove is filled with a desiccant. The desiccant can continuously absorb moisture in the humid air passing through the hollow groove to achieve the purpose of dehumidification. Exhaust holes are provided on both sides of the hollow groove. The exhaust holes can allow the dry air after dehumidification to be discharged smoothly, realize the circulation of air, and ensure the dehumidification effect.

[0032] There are at least four sets of PLC control system modules 41, each connected via wiring to four sets of dehydration filter cartridges 2. Each set of PLC control system modules 41 independently controls a corresponding dehydration filter cartridge 2, flexibly adjusting operating parameters based on the type, quantity, and dehydration requirements of the vegetables in each dehydration filter cartridge 2 to achieve precise dehydration, improving the intelligence and efficiency of the equipment.

[0033] The proximity control switch 43 and the emergency stop switch module 44 arranged on the front of the external door of the central control box module 4 can quickly shut down the equipment when an abnormality occurs, thereby enhancing operational safety; the one-way valve pipe 5 connected to the outside cooperates with the dehumidification module 6 arranged on the front, and drives the air intake mechanism 65 through the second driving mechanism 64 on the back of the dehumidification module 6. Combined with the air drying and dehumidification mechanism 66 in the inner cavity of the assembly seat 63, it can continuously dry the air in the control box to prevent moisture and dust from affecting the performance of electrical components and ensure the stable operation of precision components such as PLC.

[0034] In the dehydration control system, after the PLC control system receives the trigger signal of the proximity switch, it detects based on basic electrical conditions that the power supply voltage is within the range of AC220V±10% and the grounding resistance is less than 4 ohms, the equipment safety status confirms that the emergency stop switch is in the closed state, the motor winding temperature is lower than 90°C and the vibration amplitude does not exceed 0.5mm / s, the system operation parameter conditions preset dehydration mode and material type match, and the proximity switch signal is stable and the material placement imbalance is less than 10% for startup judgment. This can ensure that the equipment starts when the power supply voltage is stable, the grounding is good, the emergency stop switch is closed, the motor temperature and vibration amplitude are normal, the material placement is balanced, and the mode matches, avoiding abnormal operation caused by electrical failure or material imbalance, which not only ensures equipment safety, but also makes the dehydration process more efficient and improves the quality consistency of clean vegetables after dehydration. A dehydration control system for a vegetable cleaning workshop, based on the above-mentioned dehydration equipment for a vegetable cleaning workshop, includes a central control box, a PLC control system, four sets of drive circuits, an emergency stop switch, four sets of proximity switches and a dehumidification device; The central control box has at least four sets of independently operated PLC control system modules 41 built in, corresponding to the closed-loop control of the four sets of dehydration filter cartridges 2; The driving circuit module 42 is electrically connected to the PLC control system module 41 and is used to adjust the speed of the dehydration filter cartridge 2 and the power of the dehumidification module 6; The proximity switch module 11 and the emergency stop switch module 44 are used to detect the balance of material placement and trigger emergency stop respectively; The dehumidification device includes an air drying and dehumidifying mechanism 66, the hollow groove of which is filled with silica gel desiccant, and a double air duct circulation system (air intake mechanism 65 + exhaust hole) is used to achieve humidity closed-loop control (target humidity range: leafy vegetables <8%RH, root vegetables <12%RH).

[0035] After the PLC control system receives the trigger signal from the proximity switch, it determines whether to start the dehydrator based on the following starting conditions: Basic electrical conditions: Check that the power supply voltage is within the range of AC220V±10% and the ground resistance is less than 4 ohms. Only when the power supply voltage is stable and the grounding is good can the equipment be started to ensure the normal operation of the equipment electrical system and avoid electrical failures and safety accidents caused by abnormal voltage or poor grounding. Equipment safety status: Confirm that the emergency stop switch is closed, the motor winding temperature is below 90°C, and the vibration amplitude does not exceed 0.5mm / s. A closed emergency stop switch indicates that the equipment is in normal standby mode, and the motor winding temperature and vibration amplitude are within the normal range, indicating that the equipment is not currently experiencing overheating or abnormal vibration issues. Ensure that the equipment is started in a safe state. System operating parameters and conditions: The preset dehydration mode matches the material type, the proximity switch signal is stable, and the material placement imbalance is less than 10%. The preset dehydration mode matches the material type, allowing the most appropriate dehydration method to be selected based on the characteristics of different clean vegetables, ensuring dehydration results. A stable proximity switch signal indicates accurate material placement detection. A material placement imbalance of less than 10% prevents the dehydration filter cartridge 2 from vibrating violently due to imbalance during high-speed rotation, which could affect equipment safety and dehydration efficiency.

[0036] The central control box is constructed of sealed stainless steel, equipped with an internal dehumidifier and wall-mounted to the workshop wall. Stainless steel is corrosion-resistant and highly robust. The seal and internal dehumidifier effectively prevent moisture, dust, and other foreign matter from entering the central control box, protecting the internal electrical components. The wall-mounted design saves floor space and facilitates equipment layout and operation. The PLC control system is an integrated programmable logic controller (PLC), which receives proximity switch signals and executes the centralized control and forward / reverse switching logic for the four dehydrators. The integrated programmable logic controller boasts high integration and reliability, quickly and accurately processing proximity switch signals to achieve centralized control and forward / reverse switching for the four dehydrators, improving the equipment's automation and operational efficiency.

[0037] The drive circuit includes a contactor group for controlling the motor's forward and reverse rotation and braking. This group is electrically connected to the PLC output terminal. Controlled by the PLC output signal, the contactor group enables the motor's forward and reverse rotation and braking, thereby controlling the rotation direction and start and stop of the dehydration filter cartridge 2 to meet the requirements of different dehydration processes. Proximity switches are installed at corresponding locations on each dehydrator to detect the presence of material and send a trigger signal to the PLC. The proximity switches accurately detect material placement and promptly provide feedback to the PLC, ensuring that the dehydrator starts when material is ready, avoiding idling and improving the rationality and efficiency of equipment operation. The central control box is made of stainless steel, sealed, and equipped with a dehumidifier. It is mounted on the workshop wall. The stainless steel, sealing, and dehumidifier work together to create a favorable working environment for the electrical components within the central control box, extending their service life and ensuring stable operation of the dehydration control system.

[0038] When the dehydration equipment and control system used in the vegetable cleaning workshop are working, first, when the material is placed in the dehydration filter cartridge 2, the proximity switch installed at the corresponding position of each dehydrator detects that the material is in place and sends a trigger signal to the PLC control system module 41.

[0039] Next, after receiving the trigger signal, the PLC control system module 41 begins to determine the startup conditions. It first checks basic electrical conditions, confirming that the power supply voltage is within the range of AC220V±10% and the ground resistance is less than 4 ohms. It then checks the equipment's safety status, ensuring that the emergency stop switch module 44 is closed, the motor winding temperature is below 90°C, and the vibration amplitude does not exceed 0.5mm / s. Finally, it confirms the system's operating parameters, namely, that the preset dehydration mode matches the material type, that the proximity switch signal is stable, and that the material placement imbalance is less than 10%.

[0040] When all the above starting conditions are met, the PLC control system module 41 controls the first drive mechanism 25 to start up through the drive circuit module 42. The first drive mechanism 25 drives the second pulley 23 to rotate, which transmits power to the first pulley 22 via the transmission belt 24, thereby causing the dehydration filter cartridge 2 to rotate, dehydrating the clean vegetables using centrifugal force. The evenly spaced drainage holes on the outside of the dehydration filter cartridge 2 facilitate water drainage, and the sealed bearings 21 on the upper and lower ends of the cartridge ensure rotational stability and sealing.

[0041] During the operation of the dehydration equipment, the speed regulating proximity switch module 11 can adjust the speed of the dehydration filter cartridge 2. If an abnormal situation occurs during operation, the operator can press the emergency stop switch module 44 to stop the equipment operation immediately.

[0042] At the same time, a dehumidifier module 6, located on the front of the central control box module 4's exterior door, dehumidifies the interior of the central control box module 4, ensuring proper operation of the internal electrical components. A second drive mechanism 64 of the dehumidifier module 6 activates an air intake mechanism 65, which draws air into an air drying and dehumidifying mechanism 66 within the interior of the assembly base 63. The desiccant within the interior of the air drying and dehumidifying mechanism 66 dries and dehumidifies the air, which is then discharged through the exhaust port.

[0043] There are at least twelve groups of shock-absorbing modules 13 at the bottom of the dehydration equipment, each of which is equipped with a damping rod.
