Description

Technical Field

[0001] The utility model relates to the technical field of waste heat boilers, in particular to a waste heat boiler. Background Art

[0002] Waste heat boilers are mainly used to recover waste heat from waste gas, waste materials or waste liquids generated in various industrial processes, and convert this heat into thermal energy or steam for use in other process processes. During use, dust, dirt and other impurities may accumulate on the heating surface and other components of the boiler. These accumulations will affect the thermal efficiency of the boiler and even cause boiler failure or safety hazards. Therefore, waste heat boilers need to be cleaned regularly.

[0003] A Chinese patent with publication number CN217383967U proposes a waste heat boiler with an automatic ash cleaning function; the ash scraping mechanism is driven to reciprocate in the horizontal direction by extending and retracting the piston rod of the cylinder, so that the ash attached to the inner wall of the waste heat boiler is scraped off by the ash scraping brush body abutting against the side surfaces inside the waste heat boiler body, thereby achieving the purpose of cleaning the ash.

[0004] Although the above technical solution can drive the brush body to scrape off the soot attached to the inner wall of the waste heat boiler; however, in actual use, the waste heat boiler will reach a high temperature of several hundred degrees during daily operation, and the brush body is often inside the waste heat boiler. This results in: on the one hand, the brush body will be continuously exposed to high temperature when not in use, resulting in a reduction in the service life of the brush body; on the other hand, the brush body is a wearing part, and the brush body is located inside the boiler, which makes it difficult to replace, causing trouble for the staff.

[0005] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In view of the above-mentioned defects, the purpose of the utility model is to provide a waste heat boiler equipped with a detachable cleaning component, which can spray high-pressure water to clean the inside of the boiler when cleaning is needed, and can be taken out of the boiler when cleaning is not needed, and will not be affected by the high temperature inside the boiler.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a waste heat boiler, comprising: a boiler body and a cleaning component;

[0008] An operation port is provided on one side wall of the boiler body, and a cleaning slide rail is provided on the inner side wall of the boiler body;

[0009] The cleaning assembly comprises a bracket slidably mounted in the cleaning slide rail, a high-pressure water nozzle is mounted on the bracket, and the high-pressure water nozzle is connected to an external water supply source.

[0010] According to a waste heat boiler described in the utility model, elastic members are connected to two opposite sides of the bracket, free ends of the two elastic members are connected to clamping plates corresponding to the clamps of the cleaning slide rail, and tops of the two clamping plates are connected to auxiliary plates.

[0011] According to a waste heat boiler described in the utility model, the bottom of the bracket is connected to a shaft seat, the bottom of the shaft seat is rotatably connected to a pulley, and the side wall surface of the pulley is in contact with the inner bottom surface of the cleaning slide rail.

[0012] According to a waste heat boiler described in the utility model, the clamping plate is rotatably mounted with pulleys at positions on both upper and lower sides corresponding to the clamp of the cleaning slide rail, and the side wall surfaces of all the pulleys are in contact with the surface of the clamp of the cleaning slide rail.

[0013] According to the waste heat boiler described in the utility model, the top of the bracket is connected with a pipe clamp, and the high-pressure water nozzle is fixed to the top of the bracket through the pipe clamp.

[0014] According to the waste heat boiler described in the utility model, a sealing plate that can be slidably opened is provided at the operation port, and a pipe inlet is opened on the sealing plate.

[0015] The utility model provides a waste heat boiler, which has the following beneficial effects:

[0016] 1. By sliding the high-pressure water nozzle and the cleaning assembly in the cleaning slide rail, the high-pressure water flow of the high-pressure water nozzle can be used to push itself and the bracket to move along the cleaning slide rail, and at the same time, the high-pressure water flow is sprayed on the inner wall of the boiler body to clean the soot; by removing the bracket from the cleaning slide rail, the bracket and the high-pressure water nozzle will not be affected by the high temperature inside the boiler body.

[0017] 2. By pushing the card plate into the clip of the cleaning slide rail through the elastic part, the clips of the cleaning slide rails on the two opposite sides of the bracket can be kept in a relatively sliding state, so that the bracket can be slid and installed on the cleaning slide rail; by connecting auxiliary plates on the top of the two card plates, it is convenient for the staff to pinch the card plate for installation operation.

[0018] 3. By closing the sealing plate, it can prevent high-pressure water from splashing out from the operating port during cleaning, avoiding water splashing on the workers; and the sealing plate is provided with a pipe inlet, which can provide an entry path for the pipe connecting the high-pressure water nozzle and the external water supply source.

[0019] 4. By using a pulley instead of the friction between the pallet and the clip of the cleaning slide rail, the resistance when the bracket moves can be reduced, making the bracket move more smoothly. At the same time, it also prevents the pallet from rubbing against the clip of the cleaning slide rail for a long time, thereby extending the service life of the pallet.
