Description

Technical Field

[0001] This application belongs to the field of air compressor equipment, and particularly relates to an air compressor with a multi-head single-machine control function. Background Art

[0002] Air in its natural state usually contains a certain amount of water vapor. When air is compressed to a high-pressure state by an air compressor, the water molecules in it are also compressed into a smaller volume, and a part of the water vapor still exists in the high-pressure air. At the same time, inside the air compressor, the air is forced through the compression mechanism, which causes the air temperature to rise. The increased temperature will increase the saturation of water vapor in the air, making it easier to exist in a gaseous state rather than condensing into liquid water. Therefore, there must be moisture in the high-pressure air generated by the air compressor.

[0003] Some usage scenarios require clean and dry high-pressure air. Therefore, additional dehumidification equipment or subsequent treatment processes are needed to reduce the moisture content. Many times, the purchasers are not very clear about this part. After purchasing the air compressor, they do not buy water removal equipment, resulting in the air compressor being unable to be used on site and prolonging the production waiting time.

[0034] The attached drawings are the best embodiments of an air compressor with a multi-head single machine control function. The present application will be further described in detail below with reference to the attached drawings.

[0035] An air compressor with a multi-head single-machine control function includes an air storage tank 02, a control box 01 fixedly connected to the air storage tank 02, several heads 03, and an oil-water separator 05.

[0036] Several heads 03 are each separately connected to the air storage tank 02. Inside the control box 01, there are several sub-control switches, and the sub-control switches are connected to each head 03 in one-to-one correspondence to achieve separate control of each head.

[0037] The exhaust end of the air storage tank 02 is connected to the oil-water separator 05 through a pipeline. Further, the exhaust end of the air storage tank 02 is successively connected in series with a heat dissipation device 04, an oil-water separator 05, and a filter 06.

[0038] In this embodiment, the heat dissipation device 04 includes an air cavity and a fan, and the fan performs forced air cooling on the surface of the air cavity.

[0039] The control box 01 includes a display, a box body, and several sub-control switches provided inside the box body. The number of sub-control switches is the same as the number of air compressor heads, and the sub-control switches are electrically connected to the air compressor heads one by one to separately control the heads of the air compressor.

[0040] At the same time, the sub-control switch adopts a protection switch with overcurrent and overload protection functions, which can realize the overload and overcurrent protection function of a single head and protect the motor of the head. Between the sub-control switch and the head, there is also a current detection module. The current detection module adopts the existing technology and can detect the current value on this line in real time.

[0041] Inside the box body, there is a control module, and a display is provided on the top surface of the box body. The control module is based on an STM32 single-chip microcomputer. The display, each sub-control switch, and the current detection module are all electrically connected to the control module. At the same time, the control module is connected to a timing module, and the timing module is connected to each sub-control switch to count the working time of each head.

[0042] For the entire control box, the points that are prone to overheating and catching fire are mostly the wiring points of the sub-control switches. In order to prevent the fire from spreading to other sub-control switches after one sub-control switch catches fire, in this embodiment, a partition 103 is provided inside the box body. The partition 103 divides the inside of the box body into several independent chambers, and the sub-control switches are independently arranged inside the chambers.

[0043] Further, the box body includes a main body 1 and a bottom plate 2 fixedly connected to the lower part of the main body 1 through bolts 3. The partition 103 is provided inside the main body 1. The number of independent spaces divided by the partition 103 inside the main body 1 is greater than the number of sub-control switches. Inside the chambers without sub-control switches, there are a control module and a main control switch.

[0044] A touch screen placement cavity 101 is recessed on the top surface of the described body 1. A wire insertion hole 102 runs through and connects the touch screen 101 placement cavity and the chamber inside the body 1 where the control module is arranged. A display screen is clamped inside the touch screen placement cavity 101, and its wiring passes through the wire insertion hole 102 and is connected to the control module.

[0045] To enhance the heat dissipation effect, a number of groups of heat dissipation holes 201 are provided on the bottom plate 2, with each chamber corresponding to a group of heat dissipation holes 201. The heat dissipation holes 201 are strip-shaped holes, and several strip-shaped holes are arranged at intervals.

[0046] If a fire breaks out inside a certain chamber, in this embodiment, the heat dissipation holes 201 are blocked to prevent air from flowing in. Then, after the oxygen inside the chamber is consumed, it can achieve the effect of automatic fire extinguishing. For this purpose, in this embodiment, a sealing plate 4 is slidably arranged on one side in the width direction of the heat dissipation hole 201. The covering area of the sealing plate 4 is larger than the area of the heat dissipation hole 201. The sealing plate 4 is connected with a temperature control switch 5, and the temperature control switch 5 controls the sliding of the sealing plate 4. The temperature control switch 5 is a temperature bulb, and the telescopic rod of the temperature bulb is fixedly connected with the sealing plate 4. When a fire breaks out inside the chamber and the temperature rises, the telescopic rod of the temperature bulb extends, pushing the sealing plate 4 towards the heat dissipation hole 201 until the heat dissipation hole 201 is blocked, closing the entire chamber and preventing new air from flowing in.

[0047] To guide the sealing plate 4, a guide rail 6 is fixed on the bottom plate 2. The guide rail 6 is arranged on both sides of the sealing plate 4, and the sealing plate 4 is slidably connected with the guide rail 6. The cross-sectional shape of the guide rail 6 is L-shaped, and the end of the sealing plate 4 is clamped at the bottom of the guide rail 6.

[0048] Since each sub-control switch and other electrical components inside the chamber need to be connected to the control module through a cable, through holes are provided on the partition plate 103 for threading. To prevent new air from flowing in through the through holes during a fire, a wire threading device 7 is arranged inside the through holes. The wire threading device 7 includes an annular skeleton 701 with an annular chamber. The inner wall of the annular skeleton 701 is arranged in a hollow pattern. A ring-shaped capsule 703 is arranged inside the chamber of the annular skeleton 701. The capsule 703 is filled with a material that can undergo a phase change when heated, such as methanol or acetone. The boiling point of methanol is 64.7 °C, and the boiling point of acetone is 56.5 °C under normal conditions.

[0049] The annular skeleton 701 is coaxially inserted into the through hole of the partition plate 103. The outer wall of the annular skeleton 701 abuts against the inner wall of the through hole. A ring-shaped clamping plate 702 protrudes from the end of the annular skeleton 701, and the clamping plate 702 abuts against the vertical surface of the partition plate 103. The wire passes through the inside of the annular skeleton 701.

[0050] Under normal circumstances, the substance inside the capsule 703 is in a liquid state. When a fire occurs, the temperature inside the chamber rises, and the substance inside the capsule 703 vaporizes, causing the capsule 703 to expand. The surface of the capsule 703 contacts the wire through the hollow area on the inner wall of the annular skeleton 701, and together with the wire, seals the through-hole on the partition plate 103, thereby achieving the effect of sealing the chamber.

[0051] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present application.
