Model utility content
Technical problem to be solved in the utility model is to provide a kind of cooler that can improve inwall anti-corrosion capacity, this cooler greatly can reduce humid air to cooler inner wall corrosion, avoids because the rust deposite of cooler inwall is along with high velocity air knot shortening device safe operation cycle on impeller.
The technological scheme solved the problems of the technologies described above is:
A kind of cooler that can improve inwall anti-corrosion capacity, it comprises cooler casing, cooler core, upper isolation gusset, lower isolation gusset, cooler core is arranged in cooler casing, the upper and lower two ends of inwall that upper isolation gusset and lower isolation gusset are separately fixed at cooler casing, its improvements are, the cylindrical inner wall and end flat of cooler casing lay one deck corrosion resistant plate, this layer of corrosion resistant plate closely splices connection by polylith corrosion resistant plate, the top and bottom of the corrosion resistant plate of the both sides laying of cylinder inboard wall are connected with the both sides of lower isolation gusset with the upper isolation gusset in cooler casing respectively.
The above-mentioned cooler that can improve inwall anti-corrosion capacity, by being evenly equipped with multiple pin-and-hole on the polylith corrosion resistant plate that described cooler casing inwall is laid, stainless steel pin is welded to connect through pin-and-hole and cooler casing inwall, and the seam crossing between adjacent corrosion resistant plate is filled with a sealing by poly epoxy resin material.
The above-mentioned cooler that can improve inwall anti-corrosion capacity, the joint of the corrosion resistant plate that described cooler casing inwall is laid and upper isolation gusset, lower isolation gusset is filled with a sealing by poly epoxy resin material.
The beneficial effects of the utility model are:
The utility model lays one deck corrosion resistant plate on cooler inwall, greatly can reduce humid air to cooler inner wall corrosion, cooler inwall is avoided to produce rust deposite in the compression process of high speed humid air, prevent from rust deposite dust adhesion to the blade and runner of impeller of rotor causes impeller channel to narrow, thus compression efficiency, minimizing power consumption can be improved, the rotor dynamic balancing that simultaneously also avoid band impeller is damaged and vibration of compressor is increased or surge occurs.The utility model structure is simple, enforcement is convenient, thoroughly solves the rust deposite problem of cooler inwall, improves the equipment safety operation cycle, reduce repair rate, decrease the maintenance cost of equipment, ensures normally carrying out of production, has significant economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of corrosion resistant plate and cooler inwall.
In figure, mark is as follows: cooler casing 1, cooler core 2, upper isolation gusset 3, lower isolation gusset 4, corrosion resistant plate 5, pin-and-hole 6.
Embodiment
The utility model comprises cooler casing 1, is provided with cooler core 2 in cooler casing 1, and the upper isolation gusset 3 of the cold and hot gas of elongated sealing and lower isolation gusset 4 are all arranged at the top of the inwall of cooler casing 1 and bottom.
Show in figure, the cylindrical inner wall and end flat of cooler casing 1 lay one deck corrosion resistant plate, this layer of corrosion resistant plate closely splices connection by polylith corrosion resistant plate 5, the top and bottom of the corrosion resistant plate 5 of the both sides laying of cylinder inboard wall are connected with the both sides of lower isolation gusset 4 with the upper isolation gusset 3 in cooler casing 1 respectively, upper isolation gusset 3 and lower isolation gusset 4 just in time can block the two ends of stainless-steel sheet 5, and the plate face of corrosion resistant plate 5 can be close on the cylindrical inner wall of cooler casing 1 naturally.
Show in figure, by being evenly equipped with multiple pin-and-hole 6 on the polylith corrosion resistant plate 5 that cooler casing 1 inwall is laid, stainless steel pin is welded to connect through pin-and-hole 6 and cooler casing 1 inwall.
