Description

Built-in transmission type hydraulic steering mechanism

Technical Field

The utility model relates to a belt cleaning device, specific theory has related to a built-in transmission formula hydraulic steering mechanism.

Background

The tubular heat exchanger is a heat exchanger commonly used in the industrial field at present, and sludge and scale can be accumulated in a heat exchange tube or a heat exchange plate due to heat exchange and concentration of cooling water in the operation process, so that the heat exchange tube or the heat exchange plate needs to be cleaned. The conventional cleaning mode of the original heat exchanger mainly adopts manual mechanical cleaning or chemical cleaning, the heat exchanger needs to be shut down and disassembled during cleaning, cleaning personnel enter a water chamber of the heat exchanger through a manhole and clean and inspect the heat exchange pipe, and therefore the conventional cleaning mode not only takes labor cost materials, but also is poor in labor environment and influences normal operation of a unit.

For the tube type heat exchanger generating the hard scale, the chemical cleaning is carried out only after the shutdown, the hard scale cannot be removed in time, and a large amount of energy consumption is generated in the operation; when the tube type heat exchanger is seriously scaled, corrosion leakage or tube explosion accidents can be generated, so that the water quality of the tube shell side is polluted, the water quality of a heat supply system is further deteriorated, and the problems of unsafety and uneconomic production are brought.

In order to solve the problem, the utility model provides a line belt cleaning device to shell and tube heat exchanger, this belt cleaning device gets into from the lateral wall of heat exchanger head, carry the washing liquid to a style of calligraphy through steering mechanism on spraying female pipe, a style of calligraphy sprays female pipe and just sets up the heat exchange tube mouth of pipe, sprays female pipe's rotation through a style of calligraphy during the washing, can wash each heat exchange tube, when not wasing, also do not influence the normal use of heat exchanger, reach the purpose of washing on line.

Because the temperature difference between the fluid in the heat exchanger and the cleaning fluid in the cleaning device is large, the cleaning fluid conveying pipeline needs to turn, and meanwhile, the transmission of the rotating power is considered, and certain difficulty is brought to the sealing performance and the transmission stability. For example, the applicant provides a "hydraulic steering device" in the patent with the application number 201420601506.3, and provides a "rotary online washing device and a process system" in the patent with the application number 202011242100.7, both of which are connected with a rotary water inlet pipe and a rotary water outlet pipe through two ends of a fixed right-angle pipeline to realize the hydraulic steering function, the right-angle pipeline needs to be in sealing butt joint with the water inlet pipe and the water outlet pipe to ensure that cleaning liquid does not leak, and a steering transmission mechanism needs to be arranged on the outer sides of the water inlet pipe and the water outlet pipe to keep the right-angle pipeline fixed, so that the overall structure is relatively complex; because tubular heat exchanger's cleaning fluid temperature and pressure all are higher, right angle pipeline, water inlet, delivery port department lead to the transmission shaft to take place to deflect because of expend with heat and contract with cold easily, can increase the wearing and tearing of junction like this, shorten equipment life, and the complexity of its structure itself, this kind of hydraulic steering mechanism's fault rate is higher.

In order to solve the above problems, people are always seeking an ideal technical solution.
