Abstract
The invention discloses a non-axis spiral ribbon connection structure of a heat exchanger and relates to the field of the heat exchangers. The non-axis spiral ribbon connection structure comprises a shell, an embedded body and a connection cylinder, wherein the outer part of the connection cylinder is cylindrical; the connection cylinder is a containing cavity formed by surrounding a bottom surface and side walls; a small hole is formed in the bottom surface; the shell is composed of a circular pipe at the upper end and a supporting leg at the lower end; the connection cylinder is embedded into the embedded body, and then the connection cylinder and the embedded body are embedded into the circular pipe at the upper end of the shell; and a sealing cover is arranged on the top surface of the circular pipe. According to the non-axis spiral ribbon connection structure, a connection strip which is integrally cast by a spiral ribbon penetrates through the small hole formed in the bottom surface of the cylinder and then enters the containing cavity; then the connection strip is heated at a high temperature through equipment so that the connection strip is instantly fused and fully fills the whole containing cavity of the connection cylinder; and after the connection strip is cooled and condensed, the spiral ribbon is tightly connected with the connection cylinder. By changing a condition that an existing heat exchanger spiral ribbon adopts a connection manner of a bearing and a rivet, the problems that the rivet connection and machining difficulty is great, the efficiency is low and the cost is relatively high are solved.
Description
Technical field
The present invention relates to field of heat exchangers, be specifically related to a kind of heat exchanger shaftless screw ribbon attachment structure.
Background technology
Heat exchanger is a kind of equipment realizing the transmission of heat between material between two or more fluid of different temperatures, is make heat be passed to, by the fluid that temperature is higher, the fluid that temperature is relatively low. Exchanged by heat, with the needs of process conditions in satisfied production. The height of heat exchanger heat exchange efficiency, determines the height of energy utilization rate. Therefore, heat exchanger is how one of capital equipment improving energy utilization rate.
Heat exchanger occupies critical role in chemical industry, oil, power, food and other many commercial production, and in Chemical Manufacture, heat exchanger can as heater, cooler, condenser, vaporizer and reboiler etc. for they.
Existing heat exchanger ribbon connects through bearing and ribbon is connected by rivet mode with dop, and rivet interlacement difficulty of processing is big, and efficiency is low, and bearing replacing rate is big, relatively costly.
Summary of the invention
It is an object of the invention to for the deficiency in above-mentioned background technology, a kind of heat exchanger shaftless screw ribbon attachment structure is provided, change existing heat exchanger helical ribbon and adopt the connected mode of bearing and rivet, solve rivet interlacement difficulty of processing big, efficiency is low, bearing replacing rate is big, relatively costly problem.
In order to reach above-mentioned technique effect, the present invention takes techniques below scheme: a kind of heat exchanger shaftless screw ribbon attachment structure, it includes shell, chimera and connection cylinder. Described connection cylindrical outer is cylindrical, and described connection cylinder is surrounded one by bottom surface and sidewall and holds chamber, and described bottom surface is provided with aperture. Described shell is made up of the pipe of upper end and the supporting leg of lower end. Described connection cylinder is embedded in the pipe of shell upper end after being embedded into chimera together with chimera again, and the end face of described pipe is provided with sealing lid.
Connecting has certain work poor between cylinder and chimera, it can be ensured that connecting cylinder can rotate freely, and embedding chimeric Main Function in shell is reduce to connect the mechanical friction that cylinder directly produces when shell transfer is dynamic.
The long 6-7cm width having integrally casting in one end of spiral ribbon is the connection strap of 5-7mm, this connection strap is entered into accommodation chamber through the aperture connecting the setting of cylinder bottom surface, high-temperature heating is carried out by high-temperature heating device, make connection strap moment melt and fill up the whole accommodation chamber connecting cylinder, make spiral ribbon after cooled and solidified with to be connected cylinder closely coupled.
As preferably, the inward flange of described aperture equidistantly distributes multiple fixing post raised up, and the fixing post raised up rotates after being possible to prevent connection strap solidification.
As preferably, described aperture is rounded, square.
As preferably, the diameter of described connection cylinder is 14-15mm, and the diameter of the aperture on described bottom surface is 5-7mm, and the size of aperture is with satisfied energy traverse connection strap.
As preferably, described shell, connection cylinder are made by stainless steel material, and described chimera is made up of high molecular abrasion-proof material, and chimera adopts high molecular abrasion-proof material can reduce the turnover rate connecting cylinder and shell, effectively reduces cost.
The present invention is compared with prior art, there is following beneficial effect: the present invention connects the shape of cylinder mainly by design, the connection strap of spiral ribbon integrally casting is entered into accommodation chamber through the aperture connecting the setting of cylinder bottom surface, high-temperature heating is carried out by high-temperature heating device, make connection strap moment melt and fill up the whole accommodation chamber connecting cylinder, make spiral ribbon after cooled and solidified with to be connected cylinder closely coupled. Changing existing heat exchanger helical ribbon and adopt the connected mode of bearing and rivet, solve rivet interlacement difficulty of processing big, efficiency is low, and bearing replacing rate is big, relatively costly problem. On the other hand, the present invention, also by embedding chimera in shell, connects, to reduce, the mechanical friction that cylinder directly produces when shell transfer is dynamic, to reduce the turnover rate connecting cylinder and shell, effectively reduces cost. The present invention has durable for a long time, and cost is low, and the feature such as be connected firmly.
