Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of salt bath furnace cleaning equipment, and specifically relates to a cleaning device for the cooling pipes inside a salt bath furnace. Background Technology
[0002] After prolonged quenching, a large amount of impurities will adhere to the cooling pipes in the quenching salt bath, causing a decrease in the heat dissipation efficiency of the cooling pipes. The dirt on the cooling pipes contains nitrate components, and there is a risk of explosion if it is not cleaned in time.
[0003] Since the scale on cooling pipes is mainly composed of nitrates, which are soluble in water, the actual cleaning process involves first filling the salt bath with water to soak the cooling pipes and dissolve the scale. After a certain amount of scale has dissolved, the cooling pipes are then disassembled for further cleaning. This method is inefficient and time-consuming.
[0004] We subsequently improved the cleaning method by fixing the water nozzle inside the salt bath furnace and continuously spraying the cooling pipe with the nozzle. Compared to soaking and dissolving, the continuous impact of water flow on the dirt during spraying improved the descaling efficiency, but it still took a relatively long time. Moreover, since the nozzle was fixed in position, it was necessary to move the nozzle periodically and then re-fix it, making the operation quite cumbersome.
[0005] Based on this, we designed a cleaning device for the cooling pipes inside a salt bath furnace. Utility Model Content
[0006] The purpose of this invention is to provide a cleaning device for cooling pipes inside a salt bath furnace, which aims to solve the problems of cumbersome operation, low cleaning quality and efficiency in the prior art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A cleaning device for cooling pipes inside a salt bath furnace includes a support base and a cleaning mechanism. The support base includes a support plate, which has a U-shaped plate and an electric telescopic rod. The U-shaped plate is used to connect to the salt bath furnace. The electric telescopic rod is vertically arranged at both ends of the support plate, and a connecting plate is provided between the telescopic ends of the two electric telescopic rods. The cleaning mechanism includes a cleaning brush and a spray pipe arranged at the bottom of the support plate. The top of the cleaning brush has a guide rod, which passes vertically through the support plate and the top end of the guide rod is connected to the connecting plate. The spray pipe has spray nozzles for spraying the cooling pipe, and one end of the spray pipe is connected to an external water supply pipeline.
[0009] Furthermore, the cleaning brush has a fixed brush head with bristles facing the cooling pipe side.
[0010] Furthermore, the cleaning brush is a roller brush, the roller brush is equipped with a U-shaped bracket, the back plate of the U-shaped bracket is connected to the guide rod, the parallel side plates on both sides of the U-shaped bracket are rotatably connected to the rotating shaft of the roller brush, and a stepper motor is provided on one side plate, the stepper motor is drivenly connected to the rotating shaft.
[0011] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.
[0012] 1. This utility model provides a cleaning device for cooling pipes inside a salt bath furnace. A support frame houses the cleaning mechanism above the cooling pipes. During cleaning, a spray pipe continuously sprays water along the top of the cooling pipes. Water flows from the top to the bottom of the cooling pipes under gravity, dissolving nitrates in the dirt. Compared to soaking, this method uses less water. An electric telescopic rod, via a connecting plate and guide rod, moves cleaning brushes located on both sides of the cooling pipes up and down for scrubbing. Compared to water spraying, the contact scrubbing with cleaning brushes is more efficient and produces better cleaning results. This utility model is simple to operate and offers good cleaning efficiency and quality.
[0013] 2. The cleaning brush uses a roller brush, which is driven by a stepper motor to dynamically scrub the surface of the cooling pipe, which helps to further improve the cleaning effect of the cooling pipe, thereby reducing cleaning time and improving cleaning efficiency.

The stepper motor 3034 is disposed on one side plate of the U-shaped bracket 3033 and is drively connected to the rotating shaft 3035 of the roller brush 3032. The stepper motor 3034 drives the roller brush 3032 to rotate, thereby brushing the surface of the cooling pipe 102 and improving the cleaning effect. The stepper motor 3034 is selected as a waterproof motor with an IP65 protection rating to ensure its normal operation during the cleaning process. The specific model and specifications of the stepper motor can be selected and installed from commercially available products according to actual needs.
[0023] When using the cleaning device for the cooling pipes inside the salt bath furnace, the support base 200 is mounted on the top of the salt bath furnace 101 and fixed to the side wall of the salt bath furnace 101 by the U-shaped plate 202. The roller brush 3032 is set on both sides of the cooling pipe 102. The external water supply pipeline continuously supplies water to the spray pipe 301, and the spray nozzle 302 continuously sprays water from the top of the cooling pipe 102. The stepper motor 3034 drives the roller brush 3032 to rotate. At the same time, the electric telescopic rod 203 drives the roller brush 3032 to move vertically through the connecting plate 204 and the guide rod 304. The rotation of the roller brush 3032 brushes the surface of the cooling pipe 102, which helps to improve the efficiency and quality of cleaning the cooling pipe 102.
