[0021] like Figures 1 to 3 As shown, the screw air compressor housing that is easy to disassemble includes a housing assembly structure 100, a housing half cover 200 and a bottom plate 300. The bottom plate 300 is horizontally installed above the air compressor tank through the bottom feet. The housing assembly structure 100 is installed on the right side of the bottom plate 300, and the housing half cover 200 is installed on the left side. Among them, the housing assembly structure 100 is fixedly installed on the bottom plate 300, and the housing half cover 200 is detachably installed on the housing assembly structure 100 and the bottom plate 300 through bolt connection, and the bolt connection adopts M6 cylindrical head hexagon socket bolts.

[0022] The box assembly structure 100 includes box columns 110, a box top cover 130 and door panels. There are four box columns 110, which are fixedly mounted on the right corners of the top surface of the bottom plate 300 and the middle section of the front and rear edges, and are arranged perpendicular to the bottom plate 300. The box columns 110 fixed on the right corners of the top surface of the bottom plate 300 are L-shaped corner columns, and the box columns 110 fixed on the middle section of the front and rear edges of the top surface of the bottom plate 300 are straight columns, which together form a cubic box space.

[0023] Both sides of the box column 110 extend outward to form column edges 111. The column edges 111 of the I-shaped column extend to the left and right sides, and the column edges 111 of the L-shaped corner column extend to the left and front and back sides respectively. A plurality of column bolt holes 112 are opened on the column edges 111.

[0024] Party door panels are installed between the box columns 110 through the column edges 111, the controller door panel 121 and the front door panel 122 are installed between the front box columns 110, the rear door panel 124 is installed between the rear box columns 110, and the right door panel 123 is installed between the right box columns 110. A box top cover 130 is installed on the top of all the box columns 110 and the party door panels, and the left edge of the box top cover 130 extends to the left to form a top cover edge 132, and a plurality of top cover bolt holes 133 are opened on the top cover edge 132.

[0025] like Figures 2 to 3 As shown, the box half cover 200 is installed on the left side of the box assembly structure 100 and the left top surface of the bottom plate 300. A number of corner brackets 310 are installed on the top surface of the bottom plate 300 near the edge on the left side. The box half cover 200 is provided with half cover bolt holes 210 at positions matching with the column bolt holes 112, the top cover bolt holes 133 and the corner brackets 310. Through the matching of each bolt hole and the bolt, the box half cover 200 is detachably installed. The number of the top cover bolt holes 133, the column bolt holes 112 on the single column side 111 and the corner brackets 310 is 2 or more, and the number of the half cover bolt holes 210 on the single side of the box half cover 200 corresponds to the number of the top cover bolt holes 133, the column bolt holes 112 and the corner brackets 310.

When the screw air compressor is running, the door plate heat dissipation holes 125, the half cover heat dissipation holes 220 and the top cover heat dissipation holes 131 all play a role in dissipating heat from the internal structure of the housing.

[0027] Compared with the screw air compressor case in the prior art, which requires the entire upper frame to be opened, the screw air compressor case provided by the utility model is divided into two parts, namely, a case assembly structure 100 and a case half cover 200, and is a semi-detachable structure. When the case needs to be opened, only the case half cover 200 needs to be removed to expose the screw machine head, the oil and gas barrel assembly and the three filters inside the case, which include a filter, an air filter element and an oil filter element, so that the inside of the screw air compressor can be inspected or the filter element replaced. The operation is simple, convenient and fast. At the same time, the semi-detachable method can also reduce the dust entering the case.

[0028] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0029] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
