Abstract
The utility model provides a protecting jacket of a pipeline bent head. The protecting jacket of the pipeline bent head is of a frame structure composed of a top plate, two side plates and two end plates, wherein the bottom of the frame structure is open. Arc grooves B matched with the outer side wall of the pipeline bent head in the circumferential direction are correspondingly formed in the lower edges of the two end plates. The pipeline bent head is clamped and fixed between the two side plates. An air interlayer is formed between the top plate and the outer side wall of the pipeline bent head. The protecting jacket of the pipeline bent head has the following advantages of being simple in structure, convenient to install and low in manufacturing cost due to the fact that the protecting jacket can be made of waste steel plates.
Description
Technical field
The utility model belongs to the agglomerating plant field, especially a kind of sheath for the sintering channel bend.
Background technique
Strength is carried, and claims again air-flow to carry, and is a kind of concrete application of fluidization technology, and its principle is: the energy that utilizes air-flow in closed conduit along airflow direction conveying granular material.At sintering plant, strength is carried and mainly is used to the conveying sintering dedusting ash.Although strength carry have good airproof performance, the advantages such as transfer rate is high, fed distance is far away, safe and reliable, environmental protection,, the bending place of conveyance conduit elbow used often is subjected to the impact cracky of air-flow and dedusting ash particle, working life is lower.Notice of authorization number has been announced a kind of protecting sleeving for bent for the Chinese patent of CN2729495Y; this protecting sleeving for bent comprises material feeding mouth, discharge port and bend pipe, and material feeding mouth is positioned at the bottom of bend pipe, and discharge port is positioned at the top of bend pipe; there is sleeve pipe outside at bend pipe, between sleeve pipe and bend pipe, air blanketing is arranged.The utility model is mainly used in strength and carries in the process of aluminium oxide, and after the oxidized aluminium of bend pipe was worn out, material will enter into air blanketing, thereby formed backing strap between sleeve pipe and bend pipe, and bend pipe is played a protective role.But there are many shortcomings in this protecting sleeving for bent: (1) sleeve pipe is integrated, during use, sleeve pipe need to be inserted in from an end of bend pipe, then moves to the rapid wear place of bend pipe, then by flange and the bend pipe periphery that is arranged on its two ends, is tightly connected,, when if bend pipe is longer, be not easy to install; (2) sleeve pipe is generally the moulding bend pipe, and cost is higher; (3) tortuosity due to bend pipe is different with diameter, and the selection of sleeve pipe bothers; (4) the sleeve pipe tube wall is thinner, and in the process that material is filled, sleeve pipe also can be worn through, thereby, can't form backing strap.
Summary of the invention
The utility model aims to provide and a kind ofly is easy to be shaped, cost is low and the channel bend sheath of long service life.
A kind of sheath of channel bend, frame-shaped construction for the bottom opening that formed by a top board, biside plate and two end plates, the lower limb of two end plates is the corresponding B curve bath that circumferentially coordinates with the outer side wall of channel bend of offering respectively, the channel bend chucking is fixed between biside plate, forms air blanketing between the outer side wall of top board and channel bend.In the course of the work, be subjected to the impact breakage of air-flow and dedusting ash particle when channel bend after, material will enter into air blanketing,, along with material is cumulative in air blanketing, makes in air blanketing and is full of material, can play a protective role to sheath.The utlity model has following advantage: (1) is simple in structure; (2) be convenient to install; (3) sheath of the present utility model just can be made of waste and old steel plate, and fabricating cost is lower.
Further improve and be:
1) lower limb of biside plate is corresponding respectively offers the A curve bath parallel with the central axis of channel bend.Like this, can reduce the area of biside plate, reduce costs.
2) the outer side wall plane parallel of the plane of top board and channel bend, can guarantee the consistency of thickness of each point on sheath, makes sheath stable to the protective value of channel bend.
3) on the top board of air blanketing side, a protective layer is set, increases the thickness of top board, extend the working life of sheath and channel bend.
Description of drawings
Fig. 1 is the axial sectional view of the utility model along channel bend;
Fig. 2 is the circumferential sectional view of the utility model along channel bend;
Fig. 3 is overall structure figure of the present utility model.
Embodiment
Now illustrate by reference to the accompanying drawings mode of execution of the present utility model:
In conjunction with Fig. 1, Fig. 2, a kind of sheath of channel bend, frame-shaped construction for the bottom opening that formed by a top board 1, biside plate 2 and two end plates 3, the lower limb of two end plates 3 is the corresponding B curve bath 7 that circumferentially coordinates with the outer side wall 5 of channel bend of offering respectively, channel bend 4 chuckings are fixed between biside plate 2, form air blanketing 8 between the outer side wall 5 of top board 1 and channel bend.In the course of the work, be subjected to the impact breakage of air-flow and dedusting ash particle when channel bend 4 after, material will enter into air blanketing 8,, along with material is cumulative in air blanketing 8, makes in air blanketing 8 and is full of material, can play a protective role to sheath.The utlity model has following advantage: (1) is simple in structure; (2) be convenient to install; (3) sheath of the present utility model just can be made of waste and old steel plate, and fabricating cost is lower.
Further improve and be:
1) lower limb of biside plate 2 is corresponding respectively offers the A curve bath 6(parallel with the central axis 10 of channel bend as shown in Figure 3).Like this, can reduce the area of biside plate 2, reduce costs.
2) outer side wall 5 plane parallel (as shown in Figure 1) of the plane of top board 1 and channel bend, can guarantee the consistency of thickness of each point on sheath, makes sheath stable to the protective value of channel bend 4.
3) a protective layer 9(is set as shown in Figure 1 and Figure 2 on the top board 1 of air blanketing 8 sides), the thickness of increase top board 1, the working life of prolongation sheath and channel bend 4.
Protective layer of the present utility model is not limited to the concrete layer (as shown in Figure 1, 2) of pouring concrete, adopts other material or the protective layer that be used for to extend the sheath life-span that arranges on the top board of air blanketing side of the present utility model of other means of fixation all to fall in protection domain of the present utility model.
The utility model be a kind of simple in structure, cost is low, be easy to be shaped and the conveying pipeline bend sheath of long service life.
