Abstract

The invention discloses rotary drums made of glass reinforced plastic, which can replace the existing rotary drums made of wood and non-corrosive steel. The drum bodies are thin-wall cylinders welding with end plates, end-plate double T-iron and girth sheets which are made of common iron plates. Some processing pores are disposed uniformly on the end plates and girth sheets. Glass reinforced plastic is wiped manually and uniformly onto both the inner and outer flanks of the drum bodies. With solidification of glass reinforced plastic, the iron plates are tightly conglutinated with the end plates and girth sheets by these processing pores, which can prevent scaling of glass reinforced plastic and corrosion. There is heat insulating materials outside the outer flanks of glass reinforced plastic, which can be used to slow down the distribution of heat in drums to prolong soaking time. Compared with the traditional wooden rotary drums, this invention has much strongpoint including simple production, good tightness, non-leakiness, easy maintain, light weight, low cost, long life-span and save forest resources. Compared with the existing rotary drums of non-corrosive steel, this invention has lower cost, better acidresistivity and better heat-insulating property.

Description

Fiberglass drum

Technical field

The present invention relates to the novel rotary drum that a kind of process hides is used.

Technical background

In the leather leather industry, rotary drum is widely used at present.Raw hide (skin that pig, ox, sheep etc. peel) be unable to do without a large amount of rotary drums in machining processes such as immersion, liming, tanning, dyeing, skin is put into rotary drum just can carry out various processing.The cylinder staving 92% of rotary drum is to make with high-grade hardwood both at home and abroad at present, 6% staving is to make with stainless steel, common pine rotary drum is very short work-ing life, the few employing to the utmost, the rotary drum that same common iron is made easily reacts with acidifying and corrodes, influence the quality of leather, only in small part technology, adopt.The high-grade hardwood of present domestic leather machinery factory family expenses is as sinking the water tip, San Cheong etc. all behind the thick logs of country in Southeast Asia's import such as Indonesia, be processed into, this wood all is felling from the virgin forest of last a century, it is very serious to destroy the forest reserves, price rising all the way, and the easy loose leaky of the circumference plate of this kind rotary drum and end plates junction, maintenance difficult, manufacture difficulty is big, three to five years work-ing life.The present stainless steel rotary drum life-span is long, but the cost height, and heat insulation effect is poor, easily comes off after loading onto thermal insulation layer, and general producer is difficult to accept the price of this type of rotary drum.So all there are the high characteristics of cost in present rotary drum, ligneous good heat insulation, but the destruction forest is serious, easily meets sour carbonization, and the life-span is short, and manufacture difficulty is big, leakiness, easy-maintaining is difficult for putting for a long time no shortcoming; The stainless steel rotary drum life-span is long, but the price height, heat insulation effect is poor, and producer is a small amount of buying usefulness in later process only.

Summary of the invention

The object of the invention is, provide a kind of energy to substitute existing wooden rotary drum and stainless steel rotary drum, by the utilization of novel material and the improvement of structure, a kind of novel rotary drum different from the past is produced, this novel rotary drum high insulating effect, easily leak stopping, easy to maintenance, life-span is long, and good corrosion resistance makes being easy to advantage.This kind rotary drum cost is low, easily promotes, and does not need timber, has both protected the forest reserves, has protected environment again, and economic benefit and social benefit are very remarkable.

In order to achieve the above object, solution of the present invention is: a kind of fiberglass drum is made up of pinion(gear), speed reduction unit, tubular shaft, bearing, master wheel, drum body, drum door assembly.Described pinion(gear) is one and the engagement of rotary drum master wheel, forms the gear of an opposite opened transmission, plays decelerating effect simultaneously, and it is installed on the output shaft of speed reduction unit.Described speed reduction unit is one and by electric motor electric energy is transformed mechanical energy to have deceleration simultaneously, increases the transmission rig of moment of torsion, and it provides rotational power for rotary drum.Described tubular shaft is the axial workpiece that is positioned at the end face center of circle, rotary drum drum body two ends, and there is an axis hole that is used to add hot water or cold water and chemical liquid the centre.Described bearing is to be positioned on the tubular shaft, passive part, and it supports the weight of whole drum, and rotary drum is rotated, and bearing can be a rolling bearing, also can be sliding surface bearing.Described master wheel is meant the gear ring that is installed on rotary drum drum body end plate one side, and the reference circle of gear ring is consistent with the center of circle of tubular shaft, and gear ring is by on the joist steel that is bolted to end plate.Described bulging body is made up of end plate, end plate joist steel, girth sheets, thermal insulation layer, multiple glazing steel coating assembly.Its end plates, end plate joist steel, girth sheets are to make with common iron, be welded to each other by them and make a common drum skeleton that is similar to the thin wall cylindrical body, wherein joist steel is welded on the end plate, evenly be coated with last layer glass reinforced plastic with the hand formulating method at the inboard and the outer surface of end plate, girth sheets then, for prevent the internal and external layers of glass steel from end plate, girth sheets comes off, on end plate, girth sheets, evenly arrange some fabrication holes, after the curing of iron plate internal and external layers of glass steel, firmly be bonded together with end plate, girth sheets closely by these fabrication holes, play the rot-resistant effect., be used for slowing down distributing of the interior heat of rotary drum also with one deck lagging material on end plate, girth sheets glass outer steel surface, be incubated for a long time when guaranteeing rotary drum work.Thermal insulation layer rolls band bundle nation on two end plates and circumference girth sheets by multiple tracks.Outer surface at thermal insulation layer scribbles one deck glass reinforced plastic, and anti-sealing and chemical liquid flow in the thermal insulation layer, also can increase the intensity of appearance simultaneously.The triplex glass steel that is coated with on the drum body is a kind of plastics, is made with glass fibre, resin, additive and filler, and glass reinforced plastic is in light weight, and proportion has only 1/4～1/5 of plain carbon stool; The intensity height, tensile strength surpasses carbon steel; To the good corrosion resistance of general acid, alkali, salt, can simply construct in drum surface by manual.Described drum door is meant to be installed on the rotary drum girth sheets and can opens, seal, the passage of the leather of coming in and going out.

Compared with prior art, the invention has the advantages that simpler than existing traditional wooden rotary drum manufacturing, good seal, antileaking, easy to maintenance, in light weight, cost is low, good corrosion resistance, the life-span is long, can save a large amount of virgin forest resources.Than low, the good corrosion resistance of existing stainless steel rotary drum cost, and the glass reinforced plastic of this rotary drum can not come off.
