Abstract

The invention discloses a high pressure water gun wheel type conveying mechanism of tubular heater full-automatic cleaning equipment. The high pressure water gun wheel type conveying mechanism comprises a drive mechanism, a machine base, pressing wheels, a pressing wheel base, and a pressing mechanism. One pressing wheel is connected with the drive mechanism and is installed on the machine base, the pressing wheel base is provide with a slide block which is connected with a slide rail on the machine base, two pressing wheels are installed on the pressing wheel base, the machine base and the pressing wheel base are connected through the pressing mechanism, and an included angle a, of the circle center on a cross section perpendicular to the axial line, of three pressing wheels is 10-90 degrees. The high pressure water gun wheel type conveying mechanism of the tubular heater full-automatic cleaning equipment has the advantages of being simple in structure, convenient to maintain, not prone to slipping, and stable and reliable in operation.

Description

The giant wheel conveyer structure of tube still heater full automatic cleaning equipment

Technical field

The present invention relates to cleaning equipment, especially a kind of giant wheel conveyer structure of tube still heater full automatic cleaning equipment.

Background technology

Industries such as sugaring, chemical industry are extensive use of tube still heater, most typical is the employed heater of sugar industry, its setting reaches up to ten thousand heating tubes, because the influence of sugar refinery sugar refining technology, these heating tubes can deposit the calcium sulfite (incrustation) of uneven thickness in use for some time on the inwall of heating tube.These incrustation reduce the heat transfer efficiency of heater widely, to such an extent as to all will clean this every day.

Existing tube still heater cleaning equipment conveying mechanism mainly contains two kinds, on a kind of employing lifting mode is carried out the giant flexible pipe, move down, its form is to build a framework that is higher than heating tube length, the giant flexible pipe is hung on the upper end of framework, during cleaning, conveying mechanism is gone into the giant vertical transport lower end of heating tube, when cleaning finishes, conveying mechanism resets giant, because heating tube is generally grown (more than three meters), adopts this kind mode need build a frame-type conveying mechanism that rigidity is strong, it is bulky, complex structure is installed difficulty.Chinese patent 201120303949.0 specifications have been announced a kind of giant conveying mechanism of tube still heater cleaning equipment, adopt three groups of above clamping wheels straight line clamping giant flexible pipes, and it is upper and lower mobile to drive giant.This kind conveying mechanism causes easily and skids because the single-wheel group is that line contacts with the giant flexible pipe, and above wheels drive and require each wheels synchronous to need to adopt three groups (six pinch rollers), so complex structure, processing and installation difficulty.

Summary of the invention

The technical problem of solution required for the present invention provides a kind of giant wheel conveyer structure simple in structure.

For solving the problems of the technologies described above, basic design of the present invention is: utilize the cornerite that forms between three pinch rollers, under the effect of pressure, both increased giant flexible pipe and pinch roller contact area, increase the friction of giant flexible pipe again.

Realize the technical scheme that the present invention conceives substantially, it comprises driving mechanism, support, pinch roller, pinch roller seat and hold-down mechanism.Pinch roller connects with driving mechanism and is installed on the support, and the pinch roller seat is loaded onto slide block and connected with slide rail on the support, and two pinch rollers are installed on the pinch roller seat, connects with hold-down mechanism between support and the pinch roller seat.Three pinch rollers are 10 degree～90 degree at the line angle a perpendicular to the center of circle on the axial line cross section.

The invention has the beneficial effects as follows: simple in structure, easy to maintenance, be difficult for skidding, stable, reliable.

The specific embodiment

Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, pinch roller 7 connects with wheel pressing shaft and driving mechanism 6 and is installed on the support 2.Pinch roller seat 4 is loaded onto slide block and is connected with slide rail on the support 2, and pinch roller 5 and pinch roller 8 are installed on the pinch roller seat 4.Connect with hold-down mechanism 3 between support 2 and the pinch roller seat 4, hold-down mechanism 3 is a stage clip.Pinch roller 7, pinch roller 5 and pinch roller 8 are 10 degree or 45 degree or 90 degree at the line angle a perpendicular to the center of circle on the axial line cross section.Be processed with band breach groove on the pressure surface of pinch roller 7, pinch roller 5 and pinch roller 8.Giant flexible pipe 1 is placed on the band breach groove of pressure surface of pinch roller 7, compress pinch roller seat 4 by hold-down mechanism 3, band breach groove on the pressure surface of pinch roller 5 and pinch roller 8 is pressed on giant flexible pipe 1 on the pressure surface of pinch roller 7 in the band breach groove, under pressure, giant flexible pipe 1 is squeezed into blossom type, when driving mechanism 6 drove pinch roller 7 rotations, giant flexible pipe 1 upper and lower moving realized heating tube in the automatic purge heater.
