Technical Field

[0001] The utility model relates to the technical field of control cabinets, in particular to a PLC control cabinet used for sewage treatment. Background Art

[0002] PLC control cabinet refers to programmable control cabinet, which is a complete set of control cabinets, an electrical cabinet that can realize the control of motors and switches. PLC control cabinet has protection functions such as overload, short circuit, and phase loss protection. It can adapt to various industrial automation control occasions of various sizes, and can complete equipment automation and process automation control. It can achieve perfect network functions, stable performance, scalability, strong anti-interference and other characteristics. It is the core and soul of modern industry. PLC control cabinet plays an important role in sewage treatment. PLC control cabinets used for sewage treatment are generally installed in substations or distribution rooms.

[0003] Since the environment in the substation or distribution room is relatively humid and the air contains a lot of ozone, the humid air and ozone entering the PLC control cabinet will corrode and oxidize the internal electrical components. At the same time, the harmful substances produced by the combination of ozone molecules and water will accelerate the aging and damage of electrical components. For this reason, we proposed a PLC control cabinet for sewage treatment. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] A PLC control cabinet for sewage treatment comprises a cabinet body, wherein a fan is fixedly connected to the upper side of the inner wall of the cabinet body, an output end of the fan is fixedly connected to an output pipe rack, two output ends of the output pipe rack are fixedly connected to a treatment tank, the bottom surfaces of the two treatment tanks are fixedly connected to output pipes, the surfaces of the two output ends of the output pipe rack are fixedly connected to a first solenoid valve and an air inlet pipe in sequence from top to bottom, the surfaces of the two air inlet pipes are fixedly connected to a second solenoid valve, the surfaces of the two output pipes are fixedly connected to an exhaust pipe, the surfaces of the two exhaust pipes are fixedly connected to a third solenoid valve, the inner walls of the two treatment tanks are provided with a drying adsorption device with a variable covering range, when the PLC control cabinet is used, the fan is started, and under the action of the solenoid valve, the air outside the cabinet enters the treatment tank through one of the air inlet pipes, and then enters the cabinet through the output pipe, and at the same time, the air in the cabinet is discharged into another treatment tank through the output pipe rack, and finally discharged through the exhaust pipe thereon, so as to realize the heat dissipation of the PLC control cabinet.

[0006] Furthermore, the drying and adsorption device includes a first drying plate, a first ultraviolet lamp, an ultraviolet photocatalyst plate, a second ultraviolet lamp, a second drying plate, and an activated carbon plate which are fixedly connected to the inner wall of the treatment tank in sequence from top to bottom.

[0007] Furthermore, the output end of the fan passes through the upper side of the inner wall of the cabinet and extends to the top surface thereof, and the left ends of the two exhaust pipes are fixedly connected to the right side of the cabinet.

[0008] Furthermore, the two first drying plates and the two second drying plates are both made of silica gel, and the two ultraviolet light catalyst plates are both made of silicon dioxide.

[0009] Furthermore, the processing tank comprises a middle section tube and two fixed covers, and the two fixed covers are mutually engaged with one side of the middle section tube.

[0010] Furthermore, surfaces of the two processing tanks are fixedly connected with fixing parts, and the fixing parts are fixed to the cabinet body by bolts.

[0011] Furthermore, filters are provided on the lower sides of the inner walls of the two air inlet pipes.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. When using this PLC control cabinet, the fan is started. Under the action of the solenoid valve, the air outside the cabinet enters the treatment tank through one of the air inlet pipes, and then enters the cabinet through the output pipe. At the same time, the air in the cabinet is discharged into another treatment tank through the output pipe rack, and finally discharged through the exhaust pipe on it. In the process of ventilation and heat dissipation of the cabinet, after the air outside the cabinet enters one of the treatment tanks, it passes through the first drying plate to absorb the moisture carried in the air. Under the action of the ultraviolet lamp and the ultraviolet photocatalyst plate, the ozone in the air is preliminarily treated, so that the ozone is decomposed into water and oxygen. Under the action of the drying plate, the decomposed moisture is adsorbed, and finally, the ozone in the air is further adsorbed by the activated carbon plate, so that the air discharged into the cabinet is relatively dry and has a lower ozone content, which makes it difficult to cause damage to the electrical components in the cabinet. At the same time, the air in the cabinet is discharged into another treatment tank. Since the air in the cabinet will carry the heat generated by the electrical components and the temperature is relatively high, the drying plate, ultraviolet photocatalyst plate and activated carbon plate in the other treatment tank can be dried, so that the two treatment tanks can be recycled alternately, thereby ensuring the normal heat dissipation of the PLC control cabinet.

[0014] 2. Make the connectivity between the various devices in the PLC control cabinet closer, ensure its stability of use, and enhance its performance and effect.

[0015] 3. Ensure the drying effect of the drying plate so that the drying plate can be recycled. At the same time, ensure the ability of the ultraviolet photocatalyst plate to decompose ozone, so that the treatment tank can be disassembled, which is conducive to the replacement and installation of various devices in the treatment tank, making the treatment tank more stable. The filter filters the air entering the treatment tank to prevent dust from entering, ensuring the use effect of various devices in the treatment tank. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The device's "front, back, left, right" viewing angles are Figure 1 The directions in the attached drawings are taken as reference.

[0024] like Figure 1-5As shown, a PLC control cabinet for sewage treatment includes a cabinet body 1, and a fan 2 is fixedly connected to the upper side of the inner wall of the cabinet body 1. The fan 2 is an exhaust fan. The function of the exhaust fan is ventilation, that is, ventilation, to discharge the dirty air in the room and input fresh air. Specifically, the exhaust fan achieves the ventilation effect by exhausting air from indoors or outdoors. The output end of the fan 2 is fixedly connected to an output pipe rack 3, and the two output ends of the output pipe rack 3 are fixedly connected to a treatment tank 4. The bottom surfaces of the two treatment tanks 4 are fixedly connected to output pipes 5. The surfaces of the two output ends of the output pipe rack 3 are fixedly connected to a first solenoid valve 6 and an air intake pipe 7 from top to bottom. The solenoid valve is an industrial equipment controlled by electromagnetics and is a basic automation component used to control fluids. The solenoid valve is used in industry The direction, flow rate, speed and other parameters of the medium are adjusted in the industrial control system. The solenoid valve can cooperate with different circuits to achieve the expected control, and the accuracy and flexibility of the control can be guaranteed. The surfaces of the two air inlet pipes 7 are fixedly connected with the second solenoid valve 8, the surfaces of the two output pipes 5 are fixedly connected with the exhaust pipe 9, and the surfaces of the two exhaust pipes 9 are fixedly connected with the third solenoid valve 10. The inner walls of the two treatment tanks 4 are provided with a drying adsorption device with a variable covering range. The drying adsorption device includes a first drying plate 11, a first ultraviolet lamp 12, an ultraviolet photocatalyst plate 13, a second ultraviolet lamp 14, a second drying plate 15, and an activated carbon plate 16 which are fixedly connected to the inner wall of the treatment tank 4 from top to bottom. The ultraviolet photocatalyst is a kind of ultraviolet light catalyzer. The material is based on the principle of decomposition. Under the action of light, organic matter is decomposed into inorganic matter, thereby achieving the purpose of purifying the air and sterilizing and disinfecting. The characteristics of ultraviolet light catalyst are high efficiency, safety, environmental protection and energy saving. When using this PLC control cabinet, the fan 2 is started. Under the action of the solenoid valve, the air outside the cabinet enters the processing tank 4 through one of the air inlet pipes 7, and then enters the cabinet body 1 through the output pipe 5. At the same time, the air in the cabinet body 1 is discharged into another processing tank 4 through the output pipe rack 3, and finally discharged through the exhaust pipe 9 thereon. In the process of ventilation and heat dissipation of the cabinet body 1, after the air outside the cabinet enters one of the processing tanks 4, it passes through the first drying plate 11 to adsorb the moisture carried in the air. Under the action of the purple light lamp and the ultraviolet light catalyst plate 13 Under the action of the second drying plate 15, the decomposed water is adsorbed, and finally, the ozone in the air is further adsorbed by the activated carbon plate 16, so that the air discharged into the cabinet 1 is relatively dry and has a low ozone content, which makes it difficult to cause damage to the electrical components in the cabinet 1. At the same time, the air in the cabinet 1 is discharged into another processing tank 4. Since the air in the cabinet 1 carries the heat generated by the electrical components and the temperature is relatively high, the drying plate, ultraviolet light catalyst plate 13 and activated carbon plate 16 in the other processing tank 4 can be dried, so that the two processing tanks 4 can be recycled alternately, thereby ensuring the normal heat dissipation of the PLC control cabinet.

[0025] like Figure 1-2 As shown, in some embodiments, the output end of the fan 2 passes through the upper side of the inner wall of the cabinet 1 and extends to its top surface, and the left ends of the two exhaust pipes 9 are fixedly connected to the right side of the cabinet 1, so that the connectivity between the various devices in the PLC control cabinet is closer, ensuring the stability of its use, and increasing its performance and effect.

[0026] like Figure 1-5 As shown, in some embodiments, the two first drying plates 11 and the two second drying plates 15 are made of silica gel. Silica gel desiccant is a dehumidifier that can absorb excess moisture from the air to make it drier, thereby protecting the items from moisture and being reusable after drying. The two ultraviolet light catalyst plates 13 are made of silicon dioxide. The processing tank 4 includes a middle tube 401 and two fixed covers 402. The two fixed covers 402 are mutually engaged with one side of the middle tube 401. The surfaces of the two processing tanks 4 are fixedly connected with fixing members 17, and the fixing members 17 are fixed to the cabinet 1 by bolts. The lower sides of the inner walls of the two air inlet pipes 7 are provided with filter screens 18 to ensure the drying effect of the drying plates, so that the drying plates can be recycled, and at the same time ensure the decomposition ability of the ultraviolet light catalyst plate 13 on ozone, so that the processing tank 4 can be disassembled, which is conducive to the replacement and installation of various devices in the processing tank 4, making the processing tank 4 more stable. The filter screen 18 filters the air entering the processing tank 4 to prevent dust from entering, thereby ensuring the use effect of various devices in the processing tank 4.
