Embodiment Construction

[0017] The present invention will be further described below in conjunction with drawings and embodiments.

[0018] Such as figure 2 , a suction arm support device, including a support pipe 1, a connecting piece 2, a bolt 3 and a supporting sleeve 4, wherein the supporting pipes 1 are connected by a connecting piece 2, and the connecting piece 2 is two plate-shaped pieces, The connecting piece 2 is connected to the supporting pipe 1 through bolts 3 , that is, the connecting piece 2 sandwiches the supporting pipe 1 through the bolts 3 , and the supporting sleeve 4 is longitudinally fixed in the supporting pipe 4 through the bolts 3 .

[0019] In order to increase the supporting force of the support tube 4, the support tube 4 is a square tube.

[0020] The support sleeve 4 is a tubular structure, and the support sleeve 4 is made of nylon sleeve, cast iron or cast steel sleeve, preferably nylon sleeve.

[0021] First of all, the support tube 1 of this device uses a square tube...

Abstract

The invention discloses a supporting device for an air suction arm and belongs to the technical field of welding fume treatment equipment. The supporting device comprises supporting pipes, connecting pieces, bolts and supporting sleeves. The supporting pipes are connected through the connecting pieces. The connecting pieces are connected with the supporting pipes through the bolts. The supporting sleeves are longitudinally fixed in the supporting pipes through the bolts. Firstly, square pipes are adopted as the supporting pipes of the device so that part of longitudinal supporting force can be improved; and in addition, the nylon sleeves are additionally arranged in the supporting pipes so that when the bolts are fastened, the supporting force of the supporting pipes can be further improved, damage to the supporting pipes due to multiple times of bolt tightening is reduced, and the service life of the air suction arm is prolonged.

Description

technical field [0001] The invention relates to the technical field of welding fume treatment equipment, in particular to a suction arm support device. Background technique [0002] Welding fume purifier is used for purification of fume and dust generated in welding, cutting, grinding and other processes, as well as recovery of rare metals and valuable materials, etc. It can purify a large number of fine metal particles suspended in the air that are harmful to human body. [0003] The working principle of the welding fume purifier is: through the gravitational action of the fan, the welding fume exhaust gas is sucked into the equipment through the mouth of the universal flexible suction arm. , the welding fume enters the filter chamber, and the welding fume flows in the filter chamber. Using gravity and upward airflow, firstly, the coarse dust is directly dropped to the ash collection drawer, and the welding fume containing particulate dust is blocked by the cylindrical filt...
