Description

Technical Field

[0001] This utility model belongs to the field of ventilation duct technology, and in particular relates to a ventilation duct for a constant temperature equipment for logistics warehousing. Background Technology

[0002] In logistics warehousing, the design of ventilation ducts is crucial. They can regulate the temperature and humidity of the warehouse, remove harmful gases, and ensure the quality of goods and the safety of personnel. They are essential facilities for the normal operation of logistics warehousing.

[0003] Chinese patent CN219014532U discloses a ventilation structure for logistics warehousing, including an air exchange component. A connecting pipe is provided around the top of the air exchange fan housing, and a ventilation component is welded to the top of the connecting pipe. The ventilation component includes an air exchange pipe that is larger on the left and smaller on the right. A drainage pipe connected to the air exchange pipe is located below the left end of the air exchange pipe. In this ventilation structure, starting a motor activates the ventilation component. The ventilation component consists of two parts: an air exchange pipe and a drainage pipe. The drainage pipe allows condensate to slide down the air exchange pipe and into its interior, keeping the warehouse dry while preventing water from entering the motor. This design overcomes the shortcomings of ordinary ventilation structures, which are generally open-type structures prone to dampness and unable to drain condensate from the pipes. It facilitates dust reduction during ventilation and allows for convenient drainage of condensate from the ventilation pipes.

[0004] The aforementioned patent has the following problems: This patent has several drawbacks in its application. It lacks a targeted temperature control structure, making it unable to precisely control the temperature of the airflow entering the storage area. This makes it difficult to meet the temperature requirements of goods with strict storage requirements, especially equipment in warehousing and logistics. Furthermore, its condensate drainage efficiency is limited, as it lacks a dedicated collection and guidance structure, allowing condensate to accumulate on the inner walls of the pipes. Long-term accumulation can lead to pipe corrosion and shorten the equipment's lifespan. Therefore, we propose a ventilation duct for a temperature-controlled logistics warehousing system. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilation duct for a constant temperature equipment in logistics warehousing, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a ventilation duct for a constant temperature equipment in a logistics warehouse, including a pipe body, the pipe body being V-shaped, a drain outlet being provided at the bottom inflection point of the pipe body, a guide pipe being fixedly installed inside the drain outlet, a liquid guiding pipe being fixedly installed on the lower side of the guide pipe, a movable opening being provided on one side of the liquid guiding pipe, and a pull plate being slidably installed inside the movable opening; Two thermostats are symmetrically fixedly installed on the inner wall of the pipe body and located on both sides of the drain port. A fan is fixedly installed on the inner wall of the pipe body, and two dampers are rotatably installed at both ends of the pipe body.

[0007] In this technical solution, the pipe body has a unique V-shaped design. A drain port is located at the bottom bend (the lowest point of the V-shape) of the pipe body. A guide pipe is fixedly installed inside the drain port, and a guide tube is fixedly installed below the guide pipe. A movable opening is located on one side of the guide tube. A pull-out plate is slidably installed inside the movable opening, forming a simple drain valve. Two thermostats (which can be PTC heaters or heating wires) are symmetrically fixedly installed on the inner wall of the pipe body, located on both sides of the drain port. Fans are also fixedly installed on the inner wall of the pipe body to drive airflow, located at the air inlet and outlet ends of the pipe body. Two dampers are rotatably installed at both ends of the pipe body via hinges or shafts to control the opening and closing of the pipe. When the fans start, air is drawn into the V-shaped pipe body. The thermostats heat the flowing air to achieve constant temperature air supply. Due to the temperature difference between the inside and outside of the pipe, condensation will form on the inner surface of the pipe wall. Thanks to its V-shaped design, gravity allows all condensate to flow naturally to the lowest drain outlet, where it is temporarily stored in the guide pipe. When drainage is needed, simply pull out the pull plate manually or automatically, and the accumulated water will drain out through the movable outlet. The damper can be opened and closed manually or electrically to adjust the airflow or to close the pipe when not in use. The unique V-shaped structure combined with the lowest drain outlet design utilizes gravity to automatically collect condensate, ensuring thorough drainage and effectively preventing the pipe corrosion problem caused by condensate residue in the prior art. This greatly extends the service life of the equipment. At the same time, the built-in thermostat can precisely regulate the temperature of the air supplied to the storage area, meeting the stringent environmental requirements of precision logistics warehousing and solving the shortcomings of traditional ventilation ducts that only exchange air but do not control temperature.

[0008] In the above technical solution, furthermore, opening and closing electric actuators are fixedly installed on both sides of the pipe body, a horizontal plate is fixedly installed at the output end of the opening and closing electric actuator, and driving blocks are fixedly installed at both the upper and lower ends of the horizontal plate. Driving grooves are opened on both sides of the damper, and the driving blocks are slidably installed in the driving grooves.

[0009] In this technical solution, opening and closing electric actuators are fixedly installed on both sides of the pipe body. Each set of dampers is equipped with one opening and closing electric actuator. A horizontal plate and drive blocks are also installed on the other side of the damper, moving through drive slots. However, the horizontal plate is slidably installed on one side of the pipe body. This ensures stable movement and prevents the two opening and closing electric actuators from operating asynchronously, thus preventing the dampers from opening. The controller sends commands to the opening and closing electric actuators, causing the actuator's output rod to extend or retract, driving the horizontal plate to move horizontally in a straight line. The horizontal plate then drives the drive blocks at both ends to move synchronously. The drive blocks slide within the drive slots of the dampers. Due to the trajectory limitations of the slots, the horizontal linear motion is converted into the rotational motion of the dampers, thereby achieving automatic opening and closing of the dampers. The opening and closing of the dampers and their degree of opening can be precisely controlled via remote signals, eliminating the need for manual operation. This facilitates integration into intelligent warehouse management systems for precise airflow regulation. In the above technical solution, two filter screens are further fixedly installed on the inner wall of the pipe body, and the filter screens are located at the air inlet end and the air outlet end of the pipe body, respectively.

[0010] In this technical solution, two filters are fixedly installed on the inner wall of the pipe. The two filters are located at the air inlet and air outlet of the pipe, respectively. When outside air enters the pipe, it first passes through the filter at the air inlet to remove large particulate pollutants such as dust and pollen. After heating and transportation, it passes through the filter at the air outlet for secondary filtration before being sent out of the pipe, ensuring that the air delivered to the storage area is clean.

[0011] In the above technical solution, two silicone drying plates are further fixedly installed on the inner wall of the tube, and the silicone drying plates are located between the thermostat and the fan.

[0012] In this technical solution, two silica gel drying plates are fixedly installed on the inner wall of the pipe. The silica gel drying plates are made of hollow plates filled with silica gel granules. The silica gel drying plates are located between the thermostat and the fan. After the air flows through the thermostat and is heated, its relative humidity will decrease. Subsequently, the airflow passes through the silica gel drying plates, and the silica gel further absorbs the residual moisture in the air, making the air sent into the storage drier and effectively preventing the dampness problem caused by ventilation inside the storage.

[0013] In the above technical solution, a controller is further fixedly installed on one side of the pipe body. The controller is connected to the fan wire and the thermostat wire.

[0014] In this technical solution, the upper-level system sets parameters such as target temperature, fan speed, and timed tasks through a controller. The controller automatically controls the coordinated operation of each component according to the program, achieving fully automated operation of constant temperature ventilation.

[0015] In the above technical solution, a guide block is further fixedly installed on the top wall of the tube body above the guide tube, and the guide block is in the shape of an inverted triangle.

[0016] In this technical solution, the guide block is suspended at the top of the pipe. The condensate droplets fall on the inclined surface of the guide block and slide down, dripping more concentratedly and quickly into the guide pipe below. This avoids water droplets dripping randomly or lingering at other locations on the top of the pipe, further optimizing the condensate collection path and ensuring that the condensate can be quickly and completely guided to the drain outlet. This prevents water droplets from evaporating or remaining on other parts of the pipe wall, thus improving drainage reliability.

[0017] In the above technical solution, two inspection ports are further provided on one side of the pipe body, and an inspection plate is provided in the inspection port.

[0018] In this technical solution, when it is necessary to clean the filter screen, replace the silica gel drying plate, or maintain internal components, the inspection plate can be opened and the operation can be carried out directly through the inspection port without disassembling the entire pipeline.

[0019] The beneficial effects of this utility model are: 1. The ventilation duct of this constant temperature logistics storage equipment simultaneously activates two thermostats and fans via a controller. The two fans operate simultaneously, drawing in outside air through the air inlet of the duct body, heating the air through the two thermostats, and then discharging it into the logistics warehouse to maintain a constant internal temperature. After operation, the damper is closed to create a sealed space inside the duct body, cutting off heat exchange with the outside. Through the V-shaped design of the duct body and the action of the guide block, condensate is collected at the bottom of the duct body and then collected in the liquid guide pipe under the action of the guide pipe. By pulling out the pull plate, the condensate generated inside the duct body can be directly discharged, preventing condensate from accumulating inside the duct body and causing rust.

[0020] 2. The ventilation duct of this constant temperature logistics storage equipment drives the horizontal plate to move horizontally through the output end of the electric push rod. The horizontal plate drives two drive blocks to move horizontally. The drive blocks drive the dampers to rotate through the drive slots, so that the two dampers rotate relative to each other and open, thereby achieving the effect of adjusting the air intake and exhaust volume of the dampers.

A fan 7 is fixedly installed on the inner wall of the tube body 1. Two dampers 2 are rotatably installed at both ends of the tube body 1.

[0026] The tube body 1 has a unique V-shaped design. A drain outlet is located at the bottom bend (the lowest point of the V-shape) of the tube body 1. A guide tube 3 is fixedly installed inside the drain outlet, and a guide tube 16 is fixedly installed below the guide tube 3. A movable opening 17 is located on one side of the guide tube 16. A pull-out plate 11 is slidably installed inside the movable opening 17, forming a simple drain valve. Two thermostats 9 (which can be PTC heaters or heating wires) are symmetrically fixedly installed on the inner wall of the tube body 1, located on both sides of the drain outlet. A fan 7 is also fixedly installed on the inner wall of the tube body 1 to drive airflow, located at the air inlet and outlet ends of the tube body 1. Two dampers 2 are rotatably installed at both ends of the tube body 1 via hinges or shafts to control the opening and closing of the pipe. When the fan 7 is activated, air is drawn into the V-shaped tube body 1. The thermostats 9 heat the flowing air to achieve constant temperature airflow. Due to the temperature difference between the inside and outside of the tube, condensation will form on the inner surface of the tube wall. Thanks to its V-shaped design, gravity causes all condensate to flow naturally to the lowest drain outlet, where it is temporarily stored in the drain pipe 16 via the guide pipe 3. When drainage is needed, simply pull out the pull plate 11 manually or automatically, and the accumulated water will drain out through the movable port 17.

[0028] The system includes two fixed electric actuators 13 on both sides of the pipe body 1. Each set of dampers 2 is equipped with one electric actuator 13. A horizontal plate 14 and drive blocks 15 are also installed on the other side of the dampers 2, moving through drive grooves 12. However, the horizontal plate 14 is slidably mounted on one side of the pipe body 1. This ensures stable movement and prevents the dampers 2 from failing to open due to asynchronous operation of the two electric actuators 13. The controller 4 sends commands to the electric actuators 13, causing the output rods to extend or retract, driving the horizontal plate 14 to move horizontally. The horizontal plate 14 then drives the drive blocks 15 at both ends to move synchronously. The drive blocks 15 slide within the drive grooves 12 of the dampers 2. Due to the trajectory limitations of the grooves, the horizontal linear motion is converted into the rotational motion of the dampers 2, thus achieving automatic opening and closing of the dampers 2. The opening and closing of the dampers 2 can be precisely controlled via remote signals, eliminating the need for manual operation and facilitating integration into intelligent warehouse management systems for precise airflow regulation.

[0030] Two filters 6 are fixedly installed on the inner wall of the pipe body 1. The two filters 6 are located at the air inlet and air outlet of the pipe body 1, respectively. When outside air enters the pipe body 1, it first passes through the air inlet filter 6 to filter out large particulate pollutants such as dust and pollen. After being heated and transported, it passes through the air outlet filter 6 for a second filtration before being sent out of the pipe body 1, ensuring that the air delivered to the storage is clean.

[0032] Two silica gel drying plates 8 are fixedly installed on the inner wall of the pipe body 1. The silica gel drying plates 8 are made of hollow plates filled with silica gel granules.

[0036] The guide block 10 is suspended at the top of the pipe. The condensate droplets fall on the inclined surface of the guide block 10 and slide down, dripping more concentratedly and quickly into the guide pipe 3 below. This prevents the water droplets from dripping randomly or lingering at other locations on the top of the pipe, further optimizing the condensate collection path and ensuring that the condensate can be quickly and completely guided to the drain outlet.

[0037] Example 7: This example provides a ventilation duct for a constant temperature equipment in a logistics warehouse. In addition to the technical solutions of the above examples, it also has the following technical features: two inspection ports are opened on one side of the pipe body 1, and an inspection plate 5 is provided inside the inspection port.

[0038] When it is necessary to clean the filter screen 6, replace the silica gel drying plate 8, or maintain internal components, the inspection plate 5 can be opened and the operation can be carried out directly through the inspection port without disassembling the entire pipeline.

[0039] Working principle: When the device is in use, it is first installed in the ventilation area of ​​the logistics warehouse and powered on. When constant temperature ventilation is required, a signal is sent to the controller 4 via a remote signal. The controller 4 first activates multiple opening and closing electric actuators 13. The output end of the opening and closing electric actuators 13 drives the horizontal plate 14 to move horizontally. The horizontal plate 14 drives two drive blocks 15 to move horizontally. The drive blocks 15 drive the dampers 2 to rotate through the drive groove 12, so that the two dampers 2 rotate relative to each other and open, thereby opening the air inlet and outlet of the pipe body 1. Then, the controller 4 simultaneously activates two thermostats 9 and fans 7. The two fans 7 run simultaneously, drawing in outside air through the air inlet of the pipe body 1 and then heating the drawn-in air through the two thermostats 9 before discharging it into the logistics warehouse to maintain a constant internal temperature and prevent the temperature from being too high or too low, which would affect the normal operation of the internal equipment. During ventilation, filter 6 filters the intake air and removes dust from the air. Then, the silica gel drying plate 8 dries the air to prevent moisture from entering the duct and causing dampness to return to the duct. After ventilation is complete, the controller 4 activates the opening and closing electric actuator 13 to retract, closing the damper 2 and creating a sealed space inside the pipe body 1 to cut off heat exchange with the outside. Then, the fan 7 and thermostat 9 are turned off in sequence to reduce the internal heat exchange rate and the amount of condensate produced. In the areas where condensate is easily generated in the two thermostats 9, the V-shaped design of the pipe body 1 and the action of the guide block 10 cause the condensate to gather at the bottom of the pipe body 1 and, under the action of the guide pipe 3, to gather in the liquid guide pipe 16. By pulling out the pull plate 11, the condensate generated inside the pipe body 1 can be directly discharged, preventing the condensate from accumulating inside the pipe body 1 and causing the pipe body 1 to rust.
