Detailed Description

As shown in fig. 1-3, a sealing structure of a septic tank comprises an upper shell 10 and a lower shell 20, wherein a first external flange 11 is annularly arranged at a lower opening edge of the upper shell 10, a second external flange 21 is annularly arranged at an upper opening edge of the first external flange 11 and the lower shell 20 and fixedly connected with each other through a bolt 30, a sealing ring 40 is further arranged between the first external flange 11 and the second external flange 21 in a padding manner, a welding line a of the first external flange 11 and the second external flange 21 is filled with a welding rod 50, the first external flange 11 and the second external flange 21 are welded into a whole after the welding rod 50 is hot-melted, and the welding rod 50 is located outside the sealing ring 40. Firstly, the sealing ring 40 is padded between the first external flanging 11 and the second external flanging 21, then the upper shell 10 and the lower shell 20 are fixedly connected by the bolt 30 along the circumference, due to the sealing effect of the sealing ring 40, the dirt in the septic tank can be prevented from flowing out from the welding line a between the first external flanging 11 and the second external flanging 21, finally, the welding rod 50 is filled in the welding line a by the welding gun, and the melted welding rod 50 flows into the welding line a and integrally welds the first external flanging 11 and the second external flanging 21. Compared with the prior art, the welding rod 50 is added in the welding line a at the outer side of the sealing ring 40 to weld the first flanging 11 and the second flanging 21 into a whole, so that the upper shell 10 and the lower shell 20 are equivalent to a whole, and even if the sealing ring 40 fails after being used for a long time, the welding line a is melted by the welding rod 50 to fill a gap, so that the septic tank can be prevented from leaking.

As the utility model discloses a preferred scheme, first external turn-ups 11 include first horizontal turn-ups 111 and first horizontal turn-ups 111 outward flange downwardly extending the first vertical turn-ups 112 that sets up, second external turn-ups 21 include that the second is flat to be put turn-ups 211 and the vertical turn-ups 212 of second that the second is flat to be put turn-ups 211 outward flange downwardly extending the setting, bolt 30 passes first horizontal turn-ups 111, the second is flat to be put behind the turn-ups 211 and is connected with nut 60, first vertical turn-ups 112 is located the outside of the vertical turn-ups 212 of second and leaves welding seam a between the two, welding rod 50 is arranged in welding seam a and with first, the vertical turn-ups 112 of two, 212 welding is as an organic whole. The bolt 30 and the seal ring 40 are both arranged on the first flat flanging 111 and the second flat flanging 211, and the first vertical flanging 112 and the second vertical flanging 212 are both arranged in a downward-turned manner, so that the opening of the welding line a is arranged downwards, and impurities such as rainwater cannot enter the welding line a.

In order to facilitate the welding gun to melt the welding rod 50, the lower ends of the first vertical flange 112 and the second vertical flange 212 are arranged in parallel, so that the welding gun has a force application point during welding to facilitate force application, the opening of the welding seam a is downward, and the welding rod 50 is positioned at the opening of the welding seam a. It needs to be noted that, when the welding, with septic tank rotation 180 for the opening of welding seam a is up, then reuse welder welding, welding operation is convenient like this, and is respond well.

Further, an annular seal groove b is formed in the second flat flange 211, the cross section of the annular seal groove b is trapezoidal, the groove width on the side close to the first flat flange 111 is larger than the groove width on the side far from the first flat flange 111, the seal ring 40 is arranged in the annular seal groove b, and the cross section of the seal ring 40 is also trapezoidal and matched with the cross section of the annular seal groove b. The side of the sealing ring 40 close to the first flat flanging 111 is a sealing surface which is large and has good sealing effect.

The annular sealing groove b is arranged on the first flat flanging 111 on the inner side of the bolt 30, that is, the connecting part of the bolt 30 is arranged on the outer side of the annular sealing groove b, and a plurality of bolts 30 are arranged at intervals along the circumferential direction of the first and second

flat flanging

111, 211, so that the connecting strength is ensured.

In order to increase the strength of the first and second

flat flanges

111 and 211, the first and second

flat flanges

111 and 211 are provided with reinforcing ribs c.

The welding rod 50 is made of plastic material, and the upper shell 10 and the lower shell 20 are also made of plastic material. Since the upper shell 10 and the lower shell 20 are made of plastic, the welding rod 50 is heated by a welding gun to be melted, and the melted fluid enters the welding line a to realize the welding of the first externally flanged

edges

11 and 21.

Fig. 1 is a schematic view of the entire structure of the septic tank, but when welding the welding rod 50, the welding operation is performed by turning the entire septic tank 180 ° and in a posture that the upper housing 10 faces downward and the lower housing 20 faces upward, that is, the opening of the welding line a faces upward, for convenience of operation.
