SU42557A1 - Smoke Pipe Descaler - Google Patents

Description

The invention relates to flue-tube descaling machines equipped with a rotatable drive from the working shaft with a tubular mandrel through which the pipe to be cleaned is fed in the longitudinal direction, which is moved using paired grooved rollers driven by the same shaft.

In the proposed machine, the head of the tubular mandrel is provided with staggered strikers interacting with the rotation of the head with curvilinear or wedge-shaped guides mounted on the frame and serving for puncturing by striking scale, the final removal of which is performed by a set of knives located inside the head of the knives pressed by springs to the pipe being cleaned .

In FIG. Figure 1 is a front view of a smoke machine descaling machine; FIG. 2 is a side view of it; FIG. 3 is a cross-section of the head of the mandrel; FIG. 4 is a longitudinal section of it.

The tube mandrel 3 is mounted on the guide sleeve 11 attached to the frame and carries the head 2. The latter is provided with strips / 5, 21 arranged in several rows and placed in a checkerboard pattern by the springs 17 and fixed nuts 16, the shanks

(164)

boiky stand for the contour of the head. In addition, the head 2 is provided with a set of knives 18 loaded with springs 20 held by nuts 19. On the inner side, the head has a conical boring. In order to rotate the mandrel 3, a tongue 10 is fastened on it, connected by a drive with a working shaft of the motor. Curved or wedge-shaped guides 12, interacting with mandrels 15 and 21, while rotating the mandrel, are fastened near the head 2 on the frame 2. For longitudinal movement of the pipe being cleaned 13 through the mandrel serve paired grooved corrugated rollers 1.1 and 4.4, which are connected with one another. 5. The gear 3 mounted on the mandrel 3 is connected to the gear 8 of the transmission shaft, from which the rollers 7, / and 4.4 are rotated by gear 7, 6.

When the machine is started up, the rollers 1, 1 feed the scraped pipe 13 into the mandrel, with their larger ribs than that of the rollers 4,4, scaling and keeping the pipe from rotating. The pipe is chipped and incrusted into the head 2, where it simultaneously hits from two sides the impacts of the shanks of the strikers / 5 and 27, which interact with the guides 72 when the mandrel rotates. The pipe goes further from the scale to the final cleaning under the knives 8, pressed to the pipe

springs 20. Knives 18 are installed at a certain angle to the axis of the pipe for scaling up against the movement of the pipe. The cleaned scale gradually creeps from the conical surface of the head to the outside of the latter, where it is collected.

Subject invented.

A smoke tube descaling machine using a rotatable drive from a working shaft of a tubular mandrel through which a pipe to be cleaned is fed in the longitudinal direction, moved by paired grooved rollers driven by the same shaft, characterized in that and cleaning the surface of the pipe, the head 2 of the tubular mandrel 3 is provided with successively arranged in several rows and placed in a checkerboard pattern by the strikers 15, 21 for applying blows to the pipe voimi protruding beyond the outline of the head shank interacting with a frame fixed to the curved or wedge-shaped guide 12, and a set of blades 18, the springs 20 pressed against the pipe to be cleaned.
