Abstract
The utility model discloses a rake for strong corrosion working conditions, which comprises a transmission shaft (1), wherein the bottom of the transmission shaft (1) is welded with two rake arms (4) for taking the shape of an inverted V divided by a vertical line in the middle, and a group of scraper (5) is respectively welded on each one of the two rake arms (4). The rake changes the original square rake arms to two circular pipe rake arms, as the number of the rake arms is reduced, the number of transverse and vertical supports is correspondingly reduced, thereby greatly simplifying the structure of the rake arms; the simpler the structure is, the more easily the anti-corrosion treatment can be performed; furthermore, the anti-corrosion performance can be greatly improved, so that the rake is applicable to the strong corrosion working conditions. As the rake adopts the circular pipe rake arms, the anti-bending section modulus of the rake arms is great, the cross section is small, the resistance is further small, and the material consumption is low. The rake further has the advantages of light weight, simpleness in operation, long operation cycle, economic and reasonable properties, small resistance, high power transmission efficiency and good anti-corrosion performance.
Description
Technical field
The utility model relates to a kind of rake machine that is used for the deep-etching operating mode, belongs to the rake machine of the cleaning red mud that alumina industry uses.
Background technology
The dark awl high rate settling rake machine that uses at present, four square harrow arms are arranged,, increase so lacing wire is corresponding because rake arm quantity is too many, cause structure too fat to move, weight increases, and adds the rake arm and is shaped as squarely, and cross section is too big, increased the resistance that the rake machine is in operation and is subjected to greatly, because structure is complicated, anticorrosion difficulty is big more, so be not suitable for using under the operating mode with strong corrosion medium.
Summary of the invention
The purpose of this utility model is, a kind of rake machine that is used for the deep-etching operating mode is provided.It is simple in structure, is convenient to carry out preservative treatment, can satisfy need of industrial production under the deep-etching operating mode.
The technical solution of the utility model: a kind of rake machine that is used for the deep-etching operating mode, comprise power transmission shaft, the bottom of power transmission shaft and the welding of two rake arms constitute " individual " font, are welded with one group of scraper plate respectively on two rake arms.
The aforesaid rake machine that is used for the deep-etching operating mode, the bottom of described power transmission shaft constitutes " individual " font through lower part box and the welding of two rake arms.
The aforesaid rake machine that is used for the deep-etching operating mode, the other end of described two rake arms supports and the power transmission shaft welding through horizontal shape.
The aforesaid rake machine that is used for the deep-etching operating mode, described two horizontal shapes support and are welded with one group of perpendicular shape support respectively, and perpendicular shape is supported respectively and connect with two rake arms.
The aforesaid rake machine that is used for the deep-etching operating mode, described power transmission shaft, rake arm, horizontal shape support and erect shape and support and all make with carbon steel pipe.
The aforesaid rake machine that is used for the deep-etching operating mode, described power transmission shaft, rake arm, the support of horizontal shape, perpendicular shape support, scraper plate and lower part box and all pad outer surfaces are equipped with and are not less than the thick ECTFE corrosion-inhibiting coating of 1.5mm.
The aforesaid rake machine that is used for the deep-etching operating mode, described scraper plate outer surface is wound with the frp layer that thickness is not less than 8.5mm.
Compared with prior art, the utility model is with four original square harrow arms, make two pipe rake arms into, because rake arm quantity reduces, so the also corresponding minimizing of the quantity of Zhi Chenging anyhow makes the structure of rake arm simplify greatly, structure is simple more, carry out preservative treatment easily more, corrosion resistance can improve greatly, so the utility model is the rake machine that is suitable for the deep-etching operating mode.Because the utility model adopts pipe rake arm, so the module of anti-bending section of rake arm is big, cross section is little thereby be subjected to resistance less, and material usage is few.The utility model also has in light weight, and is easy and simple to handle, and the cycle of operation is long, and economical rationality is subjected to resistance less thereby power transfer efficiency is high, the advantage that corrosion resistance is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: the 1-power transmission shaft, the perpendicular shape of 2-is supported, and the horizontal shape of 3-is supported, and 4-harrows arm, 5-scraper plate, 6-lower part box.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.The utility model as shown in Figure 1.A kind of rake machine that is used for the deep-etching operating mode comprises power transmission shaft 1, and the bottom of power transmission shaft 1 and two rake arm 4 welding constitute " individual " font, are welded with one group of scraper plate 5 respectively on two rake arms 4.The bottom of power transmission shaft 1 constitutes " individual " font through lower part box 6 and two rake arm 4 welding.The other end of two rake arms 4 is through horizontal shape support 3 and power transmission shaft 1 welding.Two horizontal shapes are supported and are welded with one group of perpendicular shape support 2 on 3 respectively, and perpendicular shape is supported 2 and connect with two rake arms 4 respectively.Power transmission shaft 1, rake arm 4, the support 3 of horizontal shape and perpendicular shape are supported 2 and are all made with carbon steel pipe.Power transmission shaft 1, rake arm 4, horizontal shape support 3, perpendicular shape support 2, scraper plate 5 and lower part box 6 and all pad outer surfaces are equipped with and are not less than the thick ECTFE corrosion-inhibiting coating of 1.5mm.Scraper plate 5 outer surfaces are wound with the frp layer that thickness is not less than 8.5mm.
Operation principle of the present utility model
Mainly constitute by several parts such as power transmission shaft 1, perpendicular shape support 2, horizontal shape support 3, rake arm 4, scraper plates 5.As shown in Figure 1, power transmission shaft 1 upper end and drive unit link, and middle part and horizontal shape are supported 3 and linked, and lower part box 6 links with rake arm 4, is used to transmit moment of torsion.About two horizontal shapes support 3 and become by two big circular steel pipe respectively, the perpendicular shape support of forming with several little steel pipes 2 connects with power transmission shaft 1 with rake arm 3 together, this structure can effectively strengthen the rigidity of this rake machine system, reduce the effect of running resistance, and material usage is less relatively.About two rake arms 4 be used to strike off red mud, adopt round steel pipe rather than rectangular steel pipe, mainly be because round steel pipe to have a module of anti-bending section big, cross section is little thereby be subjected to resistance less, and advantage such as material usage is few.
Because what system adopted is carbon steel, thus must consider anticorrosion, therefore wait to harrow the machine system make finish after, must be at the thick ECTFE corrosion-inhibiting coating of its outer surface spraying 1.5mm, spraying must the whole rake machine of even and complete covering system surfaces, does not allow any leakage spray.Be used to strike off the material that falls to conical lower portion because of scraper plate 5; coating might be destroyed in the scraping process; so; must be after the spraying of whole rake machine system finishes; scraper plate must be twined with fiberglass; winding thickness is 8.5mm, adopts the method for this kind duplicate protection can effectively protect scraper plate to avoid the destruction corrosion-inhibiting coating because of scraping.
