Description

TECHNICAL FIELD

[0001] The utility model relates to chain and grate machine equipment technical field especially a chain and grate machine cooling system's water passage shaft. BACKGROUND

[0002] In the chain and grate machine - rotary kiln pellet production line, the water passage shaft of the supporting roller under the grate bed is heated to about 500 degrees, the water passage shaft is cooled by water in the middle, and is wrapped with a layer of 5cm thick rock wool, and then is wrapped with a circle of steel protective cover.

[0003] In the production process, the ball particles and dust on the grate bed fall under the suction of the circulating fan, the rock wool is burned out after long-term high temperature, corrosive flue gas and material scouring under the protective cover of the water passage shaft, the flue gas and material directly scours the surface of the water passage shaft, the gap between the protective cover and the water passage shaft increases, the protective cover also aggravates the wear of the water passage shaft during operation, which causes the local wear and leakage of the water passage shaft, and causes the system to stop and replace.

[0008] The further improvement of the technical scheme of the utility model is that the anti-drop layer is an iron plate, which is fixed outside the wear-resistant pouring layer by buckling.

[0009] The further improvement of the technical scheme of the utility model is that several mounting seats are uniformly arranged on the anti-drop layer.

[0010] The further improvement of the technical scheme of the utility model is that a support is inserted into the mounting seat, and the support is fixedly connected with a safety net arranged around the outside of the anti-drop layer.

[0011] The further improvement of the technical scheme of the utility model is that the height of the support ranges from 3cm to 6cm.

[0012] The further improvement of the technical scheme of the utility model is that the height of the V-shaped anchor nail ranges from 4cm to 7cm.

[0013] The further improvement of the technical scheme of the utility model lies in that the wear-resistant pouring layer thickness is the same as the height of the V-shaped anchoring nail.

[0014] Due to the adoption of the above technical scheme, the utility model has the following technical progress:

[0015] 1. The utility model discloses a V-shaped anchoring nail and a wear-resistant pouring layer poured on the V-shaped anchoring nail are arranged on the outer side of the water passing shaft, so that the wear resistance of the outer protection structure of the water passing shaft is improved.

[0016] 2. The utility model discloses a detachable anti-falling layer is arranged outside the wear-resistant pouring layer, so that the anti-falling layer is detached during the system shutdown and maintenance, and the local wear-resistant pouring layer falling can also be locally repaired, thereby prolonging the service life of spare parts.

[0017] 3. The utility model discloses a detachable safety net is arranged outside the anti-falling layer, so that the water passing shaft is effectively prevented from being accidentally touched. DRAWINGS

[0018] Figure 1 It is the schematic diagram of the water passing shaft of the utility model;

[0019] Among them, 1, water passing shaft, 2, bearing seat, 3, supporting wheel, 4, protection layer. CONCRETE IMPLEMENTING METHOD

[0020] The utility model will be further described in detail in combination with the drawings and examples:

[0021] In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, a particular orientation and operation, therefore, it cannot be understood as a limitation on the utility model.

[0022] In addition, in the description of the utility model, the meaning of "several" is at least two, for example, two, three and the like, unless otherwise specifically limited.

[0023] As Figure 1 shown, a chain and grate machine cooling system comprises a cooling part, a water passing shaft 1 and a drainage part connected in sequence; the water passing shaft 1 is erected on the bearing seat 2 through a plurality of supporting wheels 3; and a protection layer 4 is arranged on the outer side of the water passing shaft 1.

[0024] The protective layer 4 comprises several V-shaped anchor nails welded on the surface of the water passing shaft 1, a wear-resistant casting layer cast on the V-shaped anchor nails, and an anti-falling layer arranged outside the wear-resistant casting layer; the anti-falling layer is an iron plate and is fixed outside the wear-resistant casting layer by a buckle.

[0025] Several mounting seats are uniformly arranged on the anti-falling layer, and a support is inserted into the mounting seat; the support is fixedly connected with a safety net arranged outside the anti-falling layer, so as to prevent the water passing shaft 1 from being touched.
