Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an energy-saving control device for air compressors. Background Technology

[0002] In the industrial production sector, air compressors, as core power equipment, are widely used in many industries such as machinery manufacturing, chemical industry, mining, and food processing. Their function is to convert the mechanical energy of a prime mover into gas pressure energy, providing compressed air for various pneumatic tools, automated production lines, and pneumatic control systems. However, air compressors generally suffer from high energy consumption during operation. Statistics show that air compressor power consumption accounts for approximately 10%-35% of the total electricity consumption of industrial enterprises. Excessive energy consumption not only increases production costs for enterprises but also results in a huge waste of energy resources. Energy-saving controllers are specifically designed for the air compressor industry. They feature the ability to collect multiple data points on-site, including air compressor temperature, ambient temperature, and customer air consumption, and automatically identify and control downtime. This allows for maximum energy savings for air compressors, reducing costs for users.

[0003] Existing energy-saving controllers are mostly installed in the same control cabinet as other equipment during use. Energy-saving controllers usually operate in a high-frequency switching state, which may generate electromagnetic harmonics and radio frequency interference. If they are installed too close to other sensitive devices in the control cabinet (such as PLCs, sensors, relays, signal modules, etc.), it may lead to signal distortion, program abnormalities, and component damage. In addition, existing energy-saving controllers cannot be easily installed and disassembled, and they do not have heat dissipation effects. When a fire occurs due to aging of the wiring or poor contact, they cannot automatically extinguish the fire. Therefore, it is necessary to design an air compressor energy-saving control device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving control device for air compressors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving control device for an air compressor, including a mounting frame, a mounting mechanism provided on the front side of the mounting frame, and a protective mechanism provided on the top of the mounting mechanism;

[0006] The installation mechanism includes a protective box, which is fixedly connected to the front of the mounting frame. A sealing door is rotatably connected to the front of the protective box. Slide rails are fixedly connected to the left and right sides inside the protective box. Connecting blocks are slidably connected inside the slide rails. An energy-saving controller is provided on the left side of the connecting block. A fixed shaft is threadedly connected inside the connecting block. A fixed frame is inserted inside the connecting block. A limit shaft is threadedly connected inside the fixed frame. A limit frame is fixedly connected to the rear of the protective box. The limit frame is located behind the energy-saving controller. A fixed plate is fixedly connected to the inner side of the limit frame. A servo motor is fixedly connected to the rear side of the fixed plate. A rotating shaft is fixedly connected to the front of the servo motor. Fan blades are fixedly connected to the periphery of the rotating shaft. A smoke sensor is fixedly connected to the top inside the protective box.

There are two sets of connecting blocks and fixed shafts, which are symmetrically distributed on the left and right sides of the energy-saving controller, so that the energy-saving controller and the connecting block can be kept in a stable state through the fixed shaft.

[0008] Preferably, the fixing bracket extends through the interior of the protective box and the slide rail. The interior of the protective box, the slide rail and the connecting block are respectively provided with fixing slots, and the three fixing slots correspond to each other. The fixing bracket is inserted into the fixing slot, and the top of the limiting shaft is threaded to the interior of the protective box, so as to ensure the stability of the energy-saving controller in the protective box under the action of the fixing bracket.

[0009] Preferably, the rear side of the energy-saving controller is in contact with the front side of the limiting frame, and the rotating shaft is rotatably connected inside the fixed plate, so as to facilitate the operation of the fan blades through the rotating shaft.

[0010] Preferably, the protective box has wiring slots and heat dissipation holes on the bottom and left and right sides, respectively, and all of them are rectangular, so as to facilitate the connection of the external device's connection cable to the energy-saving controller through the wiring slots.

[0011] Preferably, the protective mechanism includes a dry powder tank, which is fixedly connected to the top of the protective box. A delivery pipe is fixedly connected to the left side of the dry powder tank. A plunger pump is fixedly connected to the periphery of the delivery pipe. A support frame is fixedly connected to the periphery of the delivery pipe. A spray pipe is fixedly connected to the inner side of the delivery pipe.

[0012] Preferably, the plunger pump and the support frame are fixedly connected to the top of the protective box, and two sets of nozzles are provided. The two sets of nozzles are symmetrically distributed on the left and right sides inside the protective box, so as to facilitate dry powder spraying when a fire occurs inside the protective box under the action of the nozzles.

[0013] Compared with the prior art, this utility model provides an energy-saving control device for air compressors, which has the following beneficial effects:

[0014] This air compressor energy-saving control device, through its installation mechanism, reduces energy consumption and saves operating costs when the air compressor is in use.

During use, the energy-saving controller can be cooled by starting a servo motor to drive the fan blades.

[0015] This air compressor energy-saving control device, through its protective mechanism, prevents leakage caused by aging circuitry or poor wiring connections when the energy-saving controller is operating inside the protective enclosure. In the event of a fire, the dry powder tank, plunger pump, delivery pipe, and nozzle form a fire extinguishing system. When a fire occurs inside the device, the plunger pump operates to spray the dry powder from the tank through the delivery pipe and nozzle, extinguishing the fire promptly and preventing it from spreading and causing greater losses. This provides comprehensive safety protection for the device. Attached Figure Description
