Description

Push rod type fire grate assembly

Technical Field

The utility model relates to an energy environmental protection field, concretely relates to push-down grate subassembly.

Background

The conventional fire grate is made of metal materials and is divided into a movable fire grate and a fixed fire grate, a plurality of fire grates (movable and non-movable) are transversely arranged, and materials are pushed to move and turn over through the reciprocating motion of the fire grates. Meanwhile, openings between grates, between grates and a wall body or on the grates are used as air openings and used as combustion-supporting air to cool the grates.

However, in the use process, when the grate gap is larger, the ventilation quantity is increased, the combustion temperature is possibly reduced, and the materials on the hearth are difficult to burn out. When the gaps of the grates are small, the grate ventilation is less to influence the burning out and the cooling of the grates, so that the grates are deformed and damaged more rapidly. Meanwhile, when the material on the fire grate is less and the fire grate is exposed for a long time, the fire grate at the position can be stably lifted, and deformation or damage can be caused.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, the utility model discloses an embodiment of push-down hearth assembly, including a plurality of grates 1, grate 1 is the cascade setting to make the material can burn step by step on hearth 2, make the burning of material more abundant.

Referring to fig. 1 and 3, each grate 1 includes a hearth 2 and a push rod 3 located above the hearth 2, and the push rod 3 can reciprocate through a driving member, which in this embodiment can be hydraulic, electric or pneumatic. The driving piece is located one side of hearth 2, and the free end detachable of push rod 3 is connected with push pedal 4, and push pedal 4 can be through the upper surface motion of the thrust edge hearth 2 of push rod 3 to can push away the material on the hearth 2 to the hearth 2 of next grade.

Referring to fig. 1 and 3, the lower surface of the push plate 4 is in contact with the upper surface of the hearth 2 to enhance the pushing effect. In addition, the lower surface of the push plate 4 is fixedly provided with a push sheet 41, and the lower end surface of the push sheet 41 is chamfered; the material residue on the hearth 2 is effectively reduced through the push sheet 41 attached to the lower surface of the hearth 2, and the pushing effect is improved.

Referring to fig. 3, the push plate 4 is arc-shaped, and the arc-shaped concave surface is far away from the driving member. The push plate 4 arranged in an arc shape can gather materials to the middle in the pushing process, so that the pushing effect can be improved. The chord length of the push plate 4 is equal to the width of the hearth 2, so that when the push plate 4 moves along the upper surface of the hearth 2 under the driving of the push rod 3, the push plate 4 can gather the materials at the edge of the hearth 2 inwards and push the materials onto the hearth 2 of the next stage, thereby improving the pushing effect.

Referring to fig. 1, the hearth 2 is made of a high temperature and wear resistant non-metallic material to improve the stability of the hearth 2 during use and to prolong the service life of the hearth 2. Meanwhile, the upper surface of the hearth 2 is obliquely arranged, and the height of the hearth 2 is reduced along the direction close to the next-stage hearth 2, so that the material on the hearth 2 is pushed onto the next-stage hearth 2.
