Abstract

The invention discloses an anchoring part which comprises a rod body, wherein one end of the rod body is provided with a connector, and the other end of the rod body is provided with anchoring claws; the middle of the rod body is fixedly connected with a plurality of anchoring claws; the rod body is formed by connecting two straight rods in parallel; two anchoring claws are welded in the middle of each straight rod; one anchoring claw in the same straight rod is obliquely arranged towards one end of the rod body connected with the connector; and the other anchoring claw is obliquely arranged towards the other end. Compared with the prior art, the anchoring part has the advantages that when 1/3 to 1/2 of the amorphous refractory and the anchoring part are worn, the anchoring claws at the front end of the anchoring part are totally worn, and the residual amorphous refractory also can be fixed by the anchoring claws which are welded in the middle of the rod body of the anchoring part, so that the service life of the amorphous refractory is prolonged; and moreover, the anchoring claws are symmetrically arranged on two sides of the rod body in a cross mode, the amorphous refractory at the periphery can be effectively fixed, and the number of the anchoring parts used in every square meter is saved by 10 to 30 percent compared with that of the anchoring parts in other shapes.

Description

Anchors

technical field

The invention relates to the technical field of industrial kilns, in particular to a structural part used for connecting and fixing monolithic refractory materials and metal wall panels of kilns.

Background technique

Anchors are widely used in cement, iron and steel smelting, ceramics, glass and other parts where unshaped refractory materials are used to fix unshaped refractory materials. Heat-resistant metal anchors are widely used in high-temperature kilns. Usually, multiple anchors are evenly distributed on the metal wall of the kiln to serve as the skeleton of the furnace lining and pour unshaped refractory materials to prevent the furnace lining from bulging and collapsing. , thereby enhancing the overall performance of the lining. According to the industrial kiln structure, furnace temperature and ambient atmosphere, different structural anchors should be selected. The existing anchors mainly include "︱" shape, "V" shape, "L" shape and "Y" shape anchors, among which "Y" shape anchors have better anchoring effect than anchors of other shapes . The "Y"-shaped anchor includes a rod body, one end of which is provided with a bent joint for welding and fixing with the metal wall of the kiln, and the other end is provided with two separate anchoring claws, which can fix different surroundings. Shaped refractories. However, this "Y"-shaped anchor has the following disadvantages in use: when the anchor is worn together with the amorphous castable, the anchor is only 1/3 to 1/2 of its original height, and the anchor is like an "L" shape. Anchor, the anchor can not fix the surrounding unshaped refractory material, resulting in the unshaped refractory material before the service life, because the anchor piece can not firmly fix the unshaped refractory material of the furnace lining, causing its whole or large area to detach.

Contents of the invention

The object of the present invention is to provide an anchor piece, which can solve the problem that the existing anchor piece cannot fix the unshaped refractory material when only 1/3-1/2 of the original height remains due to the wear and tear of the existing anchor piece.

In order to solve the above-mentioned problems, the technical solution adopted by the present invention is: the anchor piece has a rod body, one end of the rod body is provided with a connecting head, the other end is provided with an anchor claw, and the middle part of the rod body is fixedly connected with a plurality of The anchor claws extend outward.

In the technical solution of the above-mentioned anchor, a more specific technical solution may also be: four anchor claws are welded in the middle of the rod body, the rod body is formed by joining two straight rods, and the middle part of each straight rod Two anchoring claws are welded; one of the anchoring claws of the same straight rod is inclined toward one end of the rod body connected to the connecting head, and the other anchoring claw is inclined toward the other end.

Further, the four anchor claws are arranged on both sides of the rod body in a cross-symmetrical manner, and the included angle between each anchor claw and the rod body is 45°.

Further, the anchor claw in the middle of the rod body is a cylindrical rod.

Further, the anchor claw in the middle of the rod body is a flat rod.

Further, the anchor claw in the middle of the rod body is a rod with a corrugated curved section.

Owing to adopting above-mentioned technical scheme, the present invention has following beneficial effect compared with prior art:

1. When the average wear of the unshaped refractory material and the anchor is only 1/3 to 1/2, the anchor claws at the front end of the anchor are completely worn off, and the remaining unshaped refractory can still be welded to the middle of the anchor rod body The anchor claw is fixed, thereby prolonging the service life of the monolithic refractory;

2. The anchor claws arranged on both sides of the rod body in a cross-symmetrical manner can effectively fix the surrounding unshaped refractory materials, and the number of anchors used per square meter is 10-30% less than that of other shapes of anchors;

3. The anchor claw is a flat rod or a rod with a corrugated curved section, which increases the anchoring area and is beneficial to further fix the unshaped refractory material.

Detailed ways

The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

Example 1

The anchor shown in Figure 1 is mainly composed of a combination of a "V"-shaped anchor and a "Y"-shaped anchor; the "Y"-shaped anchor has a rod body 2, and one end of the rod body 2 is provided with a bent connector 3. The connector 3 is used for welding and fixing with the metal wall plate of the kiln. The other end of the rod body 2 is provided with two anchor claws 1-1 which are inclined towards both sides of the rod body 2 respectively; the rod body 2 is connected by two straight rods An anchoring claw 1-1 is provided at the end of each straight rod; four anchoring claws 1-2 are welded in the middle of the rod body 2 of the "Y" shaped anchor, and the four anchoring claws 1-2 are crossed Symmetrically arranged on both sides of the rod body 2, wherein two anchor claws 1-2 are welded in the middle of each straight rod; The other anchor claw is inclined towards the other end of the rod body 2, and the angle α between each anchor claw 1-2 and the rod body is 45°; the two anchor claws 1-2 on the same side in the middle of the rod body 2 are connected to form a "V" shape An anchor, the two anchor claws 1-2 that make up the "V" shaped anchor are perpendicular to each other. The four anchor claws 1-2 in this embodiment are all cylindrical rods, see FIG. 2 . When in use, anchor pieces with different rod body 2 lengths can be selected according to unshaped refractory materials with different thicknesses.
