Description

Technical Field

[0001] The utility model relates to a field, in particular to an explosion device for sewage treatment. Background Art

[0002] In the prior art, the patent application number CN202121953835.0 discloses an aeration device for sewage treatment, including a vertical cylinder mounted on a chassis, a rotatable sleeve inserted into the interior of the chassis, a crossbar for stirring provided on the surface of the sleeve, an auxiliary cylinder for connecting an aeration head provided on the surface of the crossbar, so that the crossbar can drive the aeration head to move through the auxiliary cylinder, and a detachable filter ring is sleeved on the surface of the aeration head. The aeration device for sewage treatment can transport the gas entering the chassis to the interior of the sleeve through the action of the vertical cylinder. Combined with the connection between the sleeve and the crossbar, the gas in the sleeve can be transported to the aeration head through the crossbar for ejection. Through the action of the aeration head, the gas can generate a certain thrust after being ejected to push the crossbar and the sleeve to rotate, so that the crossbar can stir the sewage while aerating, thereby improving the mixing of the sewage and making the mixing effect better.

[0003] However, in the technical solution disclosed in this patent, if there are impurities or objects such as seaweed in the sewage, the impurities are likely to get stuck on the cross bar and / or the connection between the cross bar and the sleeve during the rotation process, making rotation more difficult and failing to achieve the stirring effect.

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an aeration device for sewage treatment to solve the problems raised in the background technology.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model provides an aeration device for sewage treatment, the aeration device comprising a sleeve and a cutting blade, the sleeve being provided with a plurality of horizontal tubes, the horizontal tubes being provided with a plurality of aeration heads, the sleeve being sleeved on a vertical tube, the vertical tube being provided with a sealing ring for sealing the sleeve, a bent pipe being further provided at the bottom of the vertical tube, one end of the cutting blade being connected to the horizontal tube, the other end of the cutting blade being connected to the sleeve, and a mesh cover being further provided on the vertical tube for filtering large impurities.

[0006] Furthermore, the cutting blade is an arc-shaped blade, and the cutting blade is flush with the horizontal tube.

[0007] Furthermore, the cutting edge of the cutting blade is arranged on a side away from the exhaust of the degassing head.

[0008] Furthermore, the number of the cutting blades is equal to the number of the transverse tubes.

[0009] Furthermore, the partition cover comprises a vertical partition and a cone partition (8) connected to the vertical partition, and the cone partition is arranged on the vertical pipe.

[0010] Furthermore, the elbow is detachably connected to the riser.

[0011] Furthermore, a support plate for supporting the mesh cover is provided on the bent pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting up a mesh cover, larger impurities will be blocked outside the explosion head, preventing larger impurities from affecting the explosion effect and the rotation of the sleeve;

[0014] By setting a cutting blade, when the sleeve rotates, impurities in front of the horizontal tube will be cut off to avoid being stuck in the horizontal tube and the connection between the horizontal tube and the sleeve, allowing the sleeve to rotate normally and stir normally.

[0019] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The embodiments of the present invention are described below in conjunction with the drawings.

[0020] refer to Figure 1-4The aeration device for sewage treatment includes a sleeve 1 and a cutting blade 9. Six horizontal tubes 2 are provided on the sleeve 1. Two aeration heads 3 are provided on any horizontal tube 2. The sleeve 1 is sleeved on the vertical tube 5. The vertical tube 5 is provided with a sealing ring 4 for sealing the sleeve 1. A curved pipe 6 is also provided at the bottom of the vertical tube 5. One end of the cutting blade 9 is connected to the horizontal tube 2, and the other end of the cutting blade 9 is connected to the sleeve 1.
