Abstract
The utility model provides a double-diameter spring type fixing device for a plug-in piece orifice in a heat transmission pipe, which comprises a double-diameter spring, a spring seat, a rotating shaft, an axial bearing and a locking nut. The outer diameter of the small diameter end of the double-diameter spring is matched with the inner diameter of the heat transmission pipe, and the small diameter end of the double-diameter spring is inserted into the heat transmission pipe so as to enable the large diameter end of the double-diameter spring to be fixed at the outer side of the orifice. A plug-in piece in the pipe is axially fixed through the spring seat, the axial bearing, the rotating shaft, bolts, nuts and the like. The double-diameter spring type fixing device for the plug-in piece orifice in the heat transmission pipe occupies small area of the orifice and can be installed on the orifices at two ends of the pipe simultaneously and respectively, thereby overcoming the shortcomings that other like devices occupy large area of the orifices and can be only installed on the orifice at one end of the pipe. Therefore, the double-diameter spring type fixing device for the plug-in piece orifice in the heat transmission pipe can be widely applied to various tube-and-shell type heat exchangers in a vertical type or in a horizontal type.
Description
Technical field
The utility model relates to shell-and-tube heat transmission equipment pluggable unit in pipe and rotates the apparatus for eliminating sludge field automatically.
Background technology
The scale removal operation of shell-and-tube heat transmission equipment has two kinds of parking scale removal and online scale removal, and at present, major part still adopts the method for parking scale removal; Online scale removal generally is to insert pluggable unit in pipe in heat exchanger tube, utilizes the mobile kinetic energy of tube fluid medium, makes the pluggable unit in pipe rotation, thereby reaches the antiscaling, descaling purpose.Although the existing now on-line automatic rotation descalling technique of many pluggable unit in pipe, because also there are two big technical barriers in the mouth of pipe fixture of pluggable unit in pipe: the one, it is excessive that fixture accounts for orifice area, reduced mouth of pipe usable floor area, strengthened the fluid media (medium) resistance; The 2nd, fixture can only be installed at the mouth of pipe one end, comes off easily, makes the effect of the on-line automatic rotation descalling technique of pluggable unit in pipe in actual production unsatisfactory, and this is the main cause of the on-line automatic rotation descalling technique of pluggable unit in pipe not seen widespread use.
Summary of the invention
The purpose of this utility model is at the still unresolved above-mentioned technical problem of existing background technology, a kind of pair of diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixture proposed, this device accounts for that orifice area is little, the resistance of fluid medium is little, can can make the application of the on-line automatic rotation descalling technique of pluggable unit in pipe in actual production obtain Expected Results simultaneously at the installation of mouth of pipe two ends, difficult drop-off.
The utility model is achieved in that
Above-described pair of diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixture comprises two diameter springs, spring base, cod, locking nut and turning cylinder.The external diameter of two diameter spring miner diameter ends and heat exchanger tube internal diameter cooperatively interact and firmly insert in the heat exchanger tube, two diameter spring bigger diameter ends are fixed on outside the mouth of pipe, two diameter spring bigger diameter ends top is connected with spring base, cod is connected with spring base, rotating shaft is connected with cod, pluggable unit in pipe is connected by bolt and nut with rotating shaft, and locking nut is installed on rotating shaft and the cod.
Above-described pair of diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixture, the external diameter of the miner diameter end of two diameter springs cooperatively interacts with the heat exchanger tube internal diameter, the hand of spiral is identical with the pluggable unit in pipe direction of rotation.
Above-described pair of diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixture, spring base has the effect of axial axis bearing, and uniformly has 2～4 beneficial discharge orifices.
Above-described pair of diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixture, the cod center has the thread that matches with rotating shaft, and the lower end is a conical design, can adopt poly-PTFE to make.
Above-described pair of diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixture, the rotating shaft afterbody has opening and pluggable unit in pipe can be clamped and be connected firmly by bolt and nut, and there is the thread that matches with cod at the middle part, the flat or squarely of top processing.
Advantage of the present utility model:
1. two diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixtures of the utility model, it is little to take orifice area, and the resistance of fluid medium is little, and can make fluid media (medium) produce useful eddy flow at mouth of pipe place, is beneficial to the rotation of pluggable unit in pipe.
2. two diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixtures of the utility model, can install simultaneously at the two ends mouth of pipe, difficult drop-off, thereby use more scope: no matter be vertical or horizontal, also no matter its fluid media (medium) is upper and lower flowing or left and right flowing, this pair of diameter spring formula heat-transfer pipe plug-in part mouth of pipe fixture all can be installed application, and is not easy to come off.
