Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, and in particular to a temperature and humidity self-regulating electrical cabinet used in a gypsum board production line. Background Art

[0002] The automated production process of gypsum boards requires frequent start and stop control of electrical equipment to ensure smooth transmission of each link. Such frequently started and stopped electrical equipment requires high-power devices in the electrical cabinet for power supply and distribution. High-power devices tend to generate more heat, and each device in the electrical cabinet needs to operate in a suitable temperature and humidity environment to increase its lifespan. Therefore, it is necessary to adjust the temperature and humidity in the electrical cabinet in time.

[0003] Conventional electrical cabinets usually have built-in cabinet air conditioners to regulate the temperature and humidity environment inside the cabinet. Although this method can regulate the temperature and humidity inside the cabinet, the cabinet air conditioner usually forms a large circulation airflow in the cabinet to cool and dehumidify, and this large circulation airflow usually flows in an empty area with low resistance. High-power devices will form large air resistance due to their structural shape, resulting in a slow air flow rate near them, making it difficult to quickly cool down the high-power devices, causing their heat generation to spread, affecting the effect of temperature and humidity regulation in the cabinet, thereby affecting the operating life of each device.

[0004] Therefore, the existing method of using cabinet air conditioners to regulate the temperature and humidity in the electrical cabinet is that its large circulating airflow makes it difficult to quickly cool down high-power devices, resulting in heat diffusion that affects the temperature and humidity regulation effect in the electrical cabinet.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figure 1 As shown, the present invention provides a temperature and humidity self-regulating electrical cabinet for a gypsum board production line, comprising:

[0049] Cabinet 1, wherein high-power devices are arranged inside the cabinet 1;

[0050] The air conditioner 2 is arranged outside the cabinet 1, and the air conditioner 2 has a cooling area and a dehumidification area inside, which is used to provide cooling and dehumidification functions;

[0051] A dual-channel pipeline 3, one end of which is connected to the interior of the cabinet 1, and the other end of which is connected to the air conditioner 2, so as to deliver external air into the cabinet 1 and exhaust the air in the cabinet 1. The dual-channel pipeline 3 includes an air supply manifold 31 and an air extraction manifold 32. Part of the pipeline of the air supply manifold 31 is placed in the cooling area and the dehumidification area, and cold air and / or dehumidified air can be selectively introduced into the interior of the cabinet 1. The air extraction manifold 32 extracts hot air and / or humid air from the cabinet 1;

[0052] The temperature detection component 4 is arranged on the door of the cabinet 1 to positively monitor the average temperature in the cabinet 1 and the temperature of each high-power device;

[0053] Among them, some branch ends of the air supply manifold 31 and the exhaust manifold 32 are arranged around each high-power device to form a laminar flow around the surface of the high-power device. The air conditioner 2 independently adjusts the flow rate of each branch of the air supply manifold 31 and the exhaust manifold 32 according to the feedback temperature of the temperature detection component 4, and can selectively increase the air flow velocity in the overheating area to improve the temperature and humidity adjustment speed.

[0054] The electrical cabinet of this embodiment mainly utilizes the air conditioner 2 to deliver cold air and / or dehumidified air into the cabinet 1 through the air supply manifold 31 of the dual-channel pipeline 3, and to extract hot air and / or humid air from the cabinet 1 through the air exhaust manifold 32 of the dual-channel pipeline 3, so that the air in the cabinet 1 is quickly replaced to achieve the purpose of regulating temperature and humidity. During this process, the temperature detection component 4 monitors the ambient temperature in the cabinet 1 and the temperature of each high-power device in real time. When the high-power device is seriously heated, the air supply manifold 31 and the air exhaust manifold 32 form a cooling laminar flow around the high-power device by adjusting the air flow rate of the corresponding branch, so as to specifically reduce the temperature of the high-power device, thereby achieving the purpose of auxiliary regulation of the temperature in the cabinet 1 and improving the speed of temperature and humidity regulation in the cabinet 1.

[0055] Compared with the existing electrical cabinets with cabinet air conditioners inside, the electrical cabinet of this embodiment can, when the air conditioner 2 replaces and adjusts the air inside the cabinet 1 through the air supply manifold 31 and the exhaust manifold 32, perform laminar cooling on overheated high-power devices through part of the pipelines of the air supply manifold 31 and the exhaust manifold 32 to assist in the air replacement in the cabinet 1, thereby speeding up the air conditioner 2 to adjust the temperature and humidity in the cabinet 1.

[0056] During this process, the air conditioner 2 automatically adjusts its total exhaust flow and total supply air flow according to the partial branch flow of the air supply manifold 31 and the exhaust manifold 32, and the total supply air flow can be greater than the total exhaust flow, so that the cabinet 1 is in a slightly positive pressure environment to reduce dust in the cabinet 1.

[0057] Based on the above embodiments, a preferred embodiment of the air supply manifold 31 and the air extraction manifold 32 is provided below.

[0058] like Figure 1 As shown, the air supply manifold 31 includes an air supply main pipe 311, an air supply branch pipe 312 and a plurality of independently working air blowing branches 313. The air supply main pipe 311 is connected to the air conditioner 2, and the air supply branch pipe 312 is connected to the inner bottom of the cabinet 1, and the air supply main pipe 311 and the air supply branch pipe 312 are directly connected;

[0059] The exhaust manifold 32 includes an exhaust main pipe 321, an exhaust branch pipe 322 and a plurality of independently working air suction branch pipes 323. The exhaust main pipe 321 is connected to the air conditioner 2, and the exhaust branch pipe 322 is connected to the inner top of the cabinet 1, and the exhaust main pipe 321 and the exhaust branch pipe 322 are directly connected.

[0060] Each blowing branch pipe 313 and each suction branch pipe 323 are arranged around each high-power device to meet the requirement that the blowing branch pipe 313 blows out gas and circulates along its surface to the other side to be absorbed by the suction branch pipe 323 to form an annular laminar flow.

[0061] Specifically, the air supply manifold 31 is composed of an air supply main pipe 311, an air supply branch pipe 312 and a plurality of blowing air branches 313, and the air extraction manifold 32 is composed of an air extraction main pipe 321, an air extraction branch pipe 322 and a plurality of air suction branches 323, and the air supply main pipe 311 is directly connected with the air supply branch pipe 312 and the diameter of the air supply branch pipe 312 is larger than the air blowing branch pipe 313, and the air extraction main pipe 321 is directly connected with the air extraction branch pipe 322 and the diameter of the air extraction branch pipe 322 is larger than the air suction branch pipe 323, so that the air supply branch pipe 312 can supply air with a large air volume and the air extraction branch pipe 322 can suck air with a large air volume, thereby quickly replacing the air in the cabinet 1;

[0062] The blowing branch 313 and the suction branch 323 can be independently controlled, so that the air volume for cooling the high-power devices can be automatically controlled according to the heating conditions of the high-power devices, making it difficult for the heat generated by the high-power devices to spread to other areas in the cabinet 1. This can not only improve the temperature and humidity adjustment speed in the cabinet 1, but also reduce the impact of heat diffusion of high-power devices on other devices.

[0063] Since the installation positions of the high-power devices in the cabinet 1 may be irregular, and the number and position of the high-power devices in the electrical cabinets controlling the various links of the gypsum board production line may also be different, the air supply manifold 31 and the air exhaust manifold 32 need to be able to make corresponding adaptation adjustments according to the distribution of high-power devices in different electrical cabinets. Based on this, the following preferred embodiments are provided.

[0064] like Figure 1 , Figure 2As shown, multi-channel flow valves 33 are arranged between the air supply main pipe 311 and the multiple air blowing branches 313, and between the air exhaust main pipe 321 and the multiple air suction branches 323. The multi-channel flow valves 33 are expandable splicing structures. The air blowing branches 313 and the air suction branches 323 can be detachably installed on the corresponding multi-channel flow valves 33 to match the number of high-power devices in the cabinet 1.

[0065] Specifically, the multi-channel flow valve 33 adopts an expandable splicing structure, so that it can be appropriately expanded according to the number of high-power devices installed in the cabinet 1. The number of channels of the multi-channel flow valve 33 matches the high-power devices, and the blowing branch pipe 313 and the suction branch pipe 323 can be independently disassembled and assembled on the multi-channel flow valve 33, that is, matching blowing branch pipes 313 and suction branch pipes 323 can be installed according to the number and position of high-power devices, so that each blowing branch pipe 313 and each suction branch pipe 323 can be placed at the high-power devices at the corresponding position for targeted cooling.

[0066] Since the multi-channel flow valve 33 adopts an expandable splicing structure, it can be expanded according to the number of high-power devices, but each blowing branch pipe 313 and each suction branch pipe 323 need to be selected according to the position to adapt the length, which leads to complex distribution of pipes in the cabinet 1. Based on this, the following preferred embodiments are provided.

[0067] like Figure 2 As shown, the multi-channel flow valve 33 includes a plurality of valve units 331 and a plurality of pipeline units 332, and the plurality of valve units 331 and the plurality of pipeline units 332 are alternately connected in sequence to form an expandable splicing structure;

[0068] The air supply main pipe 311 and the air exhaust main pipe 321 are connected to the valve unit 331 at one end of the multi-channel flow valve 33 to connect multiple valve units 331 through the pipeline unit 332. The blowing branch pipe 313 and the suction branch pipe 323 are detachably installed on the corresponding valve unit 31 to independently control the flow rate of the blowing branch pipe 313 and the suction branch pipe 323.

[0069] Specifically, the multi-channel flow valve 33 adopts a soft-connection expansion structure of a valve unit 331 and a pipeline unit 332, that is, when it is necessary to add another set of flow control channels, a valve unit 331 and a pipeline unit 332 can be directly connected. The position distribution adaptation of the valve unit 331 and the pipeline unit 332 can reduce the layout distance of the blowing branch pipe 313 and the suction branch pipe 323, thereby effectively simplifying the pipeline layout in the cabinet 1 to reduce its interference with the line.

[0070] Based on the above embodiments, the valve unit 331 needs to be able to be extended to connect to the next valve unit 311, and also needs to be able to detachably install the blowing branch pipe 313 or the suction branch pipe 323, and after the connection, based on this, the following preferred embodiments are provided.

[0071] like Figure 3 As shown, the valve unit 331 includes a valve body 333, the valve body 333 has two connection ports 334, and the two connection ports 334 are directly connected through the interior of the valve body 333, and the valve body 333 also has a flow control port 335, the flow control port 335 is connected with the two connection ports 334, and the flow area is controlled by the valve core in the valve body 333;

[0072] The pipeline unit 332 is detachably mounted on the connection port 334, and after the pipeline unit 332 is connected to the connection port 334, communication is established so that each valve unit 331 can be independently controlled by the air conditioner 2;

[0073] The blowing branch pipe 313 and the suction branch pipe 323 can be detachably installed on the corresponding flow control port 335, and the connecting port 334 and / or the flow control port 335 can be blocked by a seal, and the valve body 333 can be freely magnetically attracted to the inner wall of the cabinet 1 to match the arrangement according to the installation position of the high-power device.

[0074] Specifically, the side wall of the valve body 333 has two directly connected connection ports 334. After the two connection ports 334 are connected through the pipeline unit 332, the two valve units 331 can be directly connected, and the multi-channel flow valve 33 can be closed by sealing them.

[0075] The flow control port 335 on the side wall of the valve body 333 is controlled by the valve core to have a communication area with the two connection ports 334, so that the flow to the flow control port 335 can be adjusted by controlling the communication area, that is, the flow of the blowing branch pipe 313 or the suction branch pipe 323 can be adjusted;

[0076] In order to facilitate the arrangement of the valve unit 331 according to the position of the high-power device, the valve body 333 adopts a magnetic design and can be adsorbed on the inner wall of the electrical cabinet, which is convenient for arrangement and installation.

[0077] After the extended connection, the valve unit 331 needs to be electrically connected to the air conditioner 2 so that the air conditioner 2 can independently control each valve unit 331. Based on this, the following preferred embodiments are provided.

[0078] like Figure 3 As shown, the pipeline unit 332 includes a tube body 336, a control wire 337 is arranged on the side wall of the tube body 336, and the control wire 337 is separated at the end of the tube body 336 and provided with a plug 338;

[0079] The valve body 333 is provided with a socket 339 close to the connection port 334 , and the plug 338 matches with the socket 339 to establish communication through plugging.

[0080] Specifically, the surface of the tube body 336 has a control wire 337 bonded thereto, and both ends of the control wire 337 are separated from the tube body 336 and provided with plugs 338, so that after the tube body 336 is inserted into the connection port of the valve body 333, the plug 338 of the control wire 337 can be inserted into the jack 339 of the valve body 333 to achieve communication, and the air conditioner 2 can control each valve body 333 to work independently based on this communication channel;

[0081] The jack 339 on the valve body 333 at the end of the serial extension can be directly connected to establish communication via the control line of the air conditioner 2 .

[0082] Since the blowing branch 313 and the suction branch 323 are arranged around the high-power device to form laminar cooling, and the high-power device is generally large, it is difficult for the blowing branch 313 and the suction branch 323 to form a large-area laminar flow. Based on this, the following preferred embodiments are provided.

[0083] like Figure 4 As shown, a blowing hood 314 is provided at the end of the blowing branch pipe 313, and a suction hood 324 is provided at the end of the suction branch pipe 323, and the blowing hood 314 and the suction hood 324 are symmetrically arranged and the high-power device is sandwiched therebetween, so as to form a laminar flow around the surface of the high-power device;

[0084] The blowing branch pipe 313 and the suction branch pipe 323 can be bent and shaped arbitrarily.

[0085] Specifically, by providing an air blowing hood 314 on the air blowing branch pipe 313 and an air suction hood 324 at the end of the air suction branch pipe 323, the blown air flow can spread to the surroundings to cover the high-power devices, and the absorption area is expanded to prevent the hot air flow from overflowing, thereby increasing the laminar flow coverage area and improving the cooling speed;

[0086] Moreover, the blowing branch pipe 313 and the suction branch pipe 323 can be bent and shaped arbitrarily, and the positions of the blowing cover 314 and the suction cover 324 can be adjusted according to the structural shape of the high-power device so that the laminar flow generated by them can cover as much area of ​​the high-power device as possible.

[0087] Since part of the air flow blown out from the air blowing hood 314 directly impacts the surface of the high-power device and the backflow blocks the blown air flow, it makes it difficult for the surface heat of the high-power device facing the air flow to dissipate. Based on this, in order to further improve the cooling and heat dissipation effect of the high-power device, the following preferred embodiments are provided.

[0088] like Figure 4As shown, a panel 315 is provided at the port of the air blowing cover 314, and an air blowing channel 316 is formed between the periphery of the panel 315 and the inner wall of the port of the air blowing cover 314. The panel 315 is installed close to the high-power device so that the air blowing channel 316 blows out an air flow parallel to the surface of the high-power device;

[0089] The inner wall of the panel 315 is in an arc shape and is made of a high thermal conductivity material. The air blowing branch pipe 313 forms an air flow along the arc surface of the inner wall of the panel 315 and blows the air out from the air blowing channel 316 .

[0090] Specifically, the panel 315 is made of a high thermal conductivity material and has a side facing the airflow direction set to be arc-shaped, so that the panel 315 can conduct the heat of the high-power device to its arc surface, and part of the airflow impacting its arc surface will flow around and be ejected along the blowing channel 316 to form laminar flow on the surface of the high-power device and effectively increase the cooling rate of the high-power device on the side facing the airflow impact.

[0091] Based on the aforementioned embodiments, the air conditioner 2 needs to be able to provide cool or cold air with low humidity, based on which, the following preferred embodiments are provided.

[0092] like Figure 1 , Figure 5 As shown, the air conditioner 2 has built-in sensors for detecting the temperature and humidity inside and outside the cabinet 1, and the air conditioner 2 has a dehumidification cavity 21 and a refrigeration cavity 22. After the air supply main pipe 311 partially passes through the refrigeration cavity 22, its end is connected to the dehumidification cavity 21 through the built-in pump of the air conditioner 2;

[0093] The dehumidification cavity 21 is connected to the outside of the air conditioner 2 through a filter component. The air conditioner 2 adjusts the working state of the built-in condensation component in the dehumidification cavity 21 according to the humidity difference between the inside and outside of the cabinet 1.

[0094] Specifically, the refrigeration cavity 22 is filled with refrigerant, and the air supply main pipe 311 is partially placed in the refrigerant. The air conditioner 2 can control the temperature of the refrigerant through the evaporation component, thereby effectively controlling the temperature of the air flow in the air supply main pipe 311 to achieve temperature regulation;

[0095] Since external air is directly introduced into the dehumidification cavity 21, the air conditioner 2 can reduce the moisture in the air through the condensation component to achieve the purpose of regulating the humidity, and the working state of the condensation component in the dehumidification cavity 21 is adjusted according to the difference in humidity inside and outside to maintain a suitable humidity state in the cabinet 1.

[0096] There is water collected due to condensation in the dehumidification chamber 21, and the collected water is usually discharged regularly. However, in the dry season, the cabinet 1 is cooled down, resulting in low humidity in the cabinet 1, which easily generates static electricity. Based on this, the following preferred embodiments are provided to maintain the humidity in the cabinet 1.

[0097] like Figure 5 As shown, a water storage tank 23 is provided at the bottom of the air conditioner 2, and the water storage tank 23 is connected to the dehumidification cavity 21 through a pipeline to hold condensed water. A humidifying pipe 231 is provided at the upper end of the water storage tank 23, and the humidifying pipe 231 is connected to the air supply branch pipe 312;

[0098] A reversing valve 317 is provided at one section of the air supply branch pipe 312, and a reversing pipe 318 is provided on the reversing valve 317. The end of the reversing pipe 318 is provided at the bottom of the water storage tank 23 and connected to introduce the air humidified by the condensed water into the humidifying pipe 231;

[0099] The connection between the humidifying pipe 231 and the air supply branch pipe 312 is located downstream of the air flow of the reversing valve 317 .

[0100] Specifically, the condensed water in the dehumidification cavity 21 in the air conditioner 2 is collected by the water storage tank 23, and one section of the air supply branch pipe 312 forms a reversing pipe 318 branch through the reversing valve 317. When the humidity in the cabinet 1 is low, the air supply branch pipe 312 can be controlled to send the air along the reversing pipe 318 into the water storage tank 23 for humidification, and then send it into the cabinet 1 through the humidification pipe 231, so as to realize the reuse of the condensed water.

[0101] The water storage tank 23 is provided with a filling port and a drain port to facilitate adding water for humidification in a dry environment and draining water for dehumidification in a humid environment.

[0102] It is worth noting that the temperature detection component 4 uses a conventional infrared temperature camera to monitor the ambient temperature at a wide angle to obtain point cloud temperature data, thereby realizing large-area temperature monitoring, effectively reducing the number of temperature sensors and reducing the difficulty of layout.

[0103] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
