Description

Electric heating smooth roller of filter cloth calender

Technical Field

The utility model relates to a filter cloth calender specifically is a filter cloth calender electric heat smooth roll.

Background

The filter cloth calender mainly comprises an electric heating smooth roller, a nylon roller and a cooling roller, wherein the rollers are arranged up and down according to the sequence of the electric heating smooth roller, the nylon roller and the cooling roller, the electric heating smooth roller has a heating function, so that the surface temperature of the electric heating smooth roller can reach about 150 ℃, after the filter cloth is centered and expanded, the nylon roller and the electric heating smooth roller are pressed and even fused to increase the strength through the hydraulic mechanism, and the surface of the filter cloth is flat and generates required gloss. In the prior art, after one end electrode terminal of the electric heating tube passes through the end face of the electric heating smooth roller, the other end electrode terminal is suspended in the inner cavity of the electric heating smooth roller, and three groups of the electric heating tube are respectively connected in series through conducting wires. However, because the temperature in the inner cavity of the electric heating smooth roller is higher, the insulation layer of the series conductor is aged quickly, and the electric heating pipe is often blown due to phase failure. And because one end of the electric heating tube is fixed and the other end is suspended, the electric heating tube is easy to be distorted and deformed at high temperature, so that the electric heating tubes are mutually contacted and fused.

Disclosure of Invention

The utility model aims at overcoming the defect of prior art, disclosing a filter cloth calender electric heat smooth roll, the technical scheme who takes is:

the utility model provides a filter cloth calender electric heat smooth roller, includes the cylinder roller that the surface is smooth becomes the mirror, stretches into respectively in the cylinder roller and rather than the end disc of both ends rigid coupling, its characterized in that: a shaft concentric with the end disc is fixedly arranged at the center of each end disc, N through holes which are uniformly arranged along the circumferential direction and have the axial direction consistent with the axial direction of the shaft are formed in the shaft, N electric heating tubes are respectively inserted into the N through holes, the tube walls at two ends of each electric heating tube are exposed out of the outer end of the shaft, the wiring terminals of the N electric heating tubes positioned outside one shaft are connected in series, the wiring terminals of the N electric heating tubes positioned outside the other shaft are divided into three groups, and one wiring terminal is led out from each group and connected with each phase power line of a three-phase power supply; n is an integer and can be divided by 3.

Furthermore, the shaft center corresponding to the three groups of the connecting terminals is fixedly connected with a half shaft concentric with the connecting terminals, three conductive slip rings are sleeved on the half shaft, the binding posts led out from the three groups of the connecting terminals are respectively connected with the three conductive slip rings, and three carbon brushes in running fit with the three conductive slip rings are respectively connected with each phase power line of the three-phase power supply.

Furthermore, a shaft bush is sleeved on the shaft close to the outer side of the end disc, and the shaft is pivoted with the calender frame through the shaft bush.

Furthermore, a chain wheel is fixedly arranged on one of the shafts and used for driving the shafts to rotate.

Further, N = 18.

Compared with the prior art, the utility model discloses the electrothermal tube both ends all inlay and establish on electric heat smooth roll terminal surface, are difficult to distortion and cause the electrothermal tube to touch each other and fuse to the wire of connecting the electrothermal tube terminal also all is located outside the electric heat smooth roll inner chamber, and the wire insulating layer is difficult to ageing, the maintenance of being convenient for simultaneously.
