In order to realize the purpose of the utility model, the technical proposal of the utility model is that:
a bottom ring with firm connection is characterized by comprising a plurality of arc-shaped base bodies, wherein water cooling pipelines are arranged in the arc-shaped base bodies, water inlet pipes and water outlet pipes communicated with the water cooling pipelines are arranged on the arc-shaped base bodies, the arc-shaped base bodies can be spliced to form an annular structure, two end surfaces of each arc-shaped base body are arranged along the normal direction of an arc line, a lug is arranged on one end surface, a clamping groove for clamping the lug is arranged on the other end surface, and the lug of each arc-shaped base body is clamped into the clamping groove of the adjacent arc-shaped base body; the riser has been arranged at the both ends of arc base member, is equipped with the through-hole on the riser, and the through-hole interpolation is equipped with the screw, and the screw top spin has connect the nut.
The lug is clamped into the clamping groove, so that the connection between the two arc-shaped substrates is tighter, the installation is simple, the connection is tight, and the looseness is not easy to occur.
Preferably, the water cooling pipes are arranged annularly. Avoid the same rotation direction arrangement to generate vortex, consume electric stove active power.
Preferably, the arc-shaped base body is provided with a hoisting threaded hole. The arc-shaped base body is convenient to hoist.
Preferably, the arc-shaped substrate is made of red copper. The red copper material has good heat dissipation.
Preferably, a filtering device is arranged at the water inlet pipe. The water cooling pipeline in the arc-shaped base body is prevented from being blocked.
Preferably, the water inlet pipe and the water outlet pipe are connected with the arc-shaped base body in a welding mode. The water inlet pipe, the water outlet pipe and the arc-shaped base body are connected and sealed.
Preferably, the cross section of the water cooling pipeline is in an 8 shape. The rigidity of the arc-shaped substrate can be increased.
Preferably, when the projection is clamped into the groove bottom of the clamping groove, a distance exists between the end faces of the adjacent arc-shaped base bodies. The arc-shaped substrates can generate thermal deformation at high temperature, and the distance between the two end surfaces can avoid the deformation of the two adjacent arc-shaped substrates after thermal deformation.
The beneficial effects of the utility model are that:
1. the utility model discloses in the draw-in groove is gone into to the lug card, makes the connection between two arc base members inseparabler.
2. The utility model discloses in adopt between welded connection inlet tube, outlet pipe and the arc base member to connect sealed.
3. The utility model discloses well arc base member can produce thermal deformation under the high temperature, and there is the interval in both ends face, can avoid producing after two adjacent arc base members thermal deformation and warp.
