Description

Technical Field

[0001] The utility model belongs to the technical field of boiler sewage discharge, and in particular relates to an automatic sewage discharge system for a steam boiler. Background Art

[0002] Steam boiler is an important equipment indispensable to industrial production. During the use of the boiler, due to the impurities and various mineral components in the water, the boiler water is heated in the boiler, which provides conditions for chemical reaction and continuous concentration of impurities in the water. When the impurities reach saturation in the boiler water, solid matter will precipitate. If it is suspended in the boiler water, it will form water slag. If it adheres to the heated surface, it will form scale. Because the thermal conductivity of scale is worse than that of steel, the heat transfer efficiency between the boiler water-cooled wall tubes and the boiler water is reduced. Therefore, after the boiler has been used for a period of time, it is necessary to remove scale and discharge sewage from the boiler to ensure the continuous operation of the boiler. Otherwise, not only a large amount of heat energy will be wasted, but also safety accidents will occur.

[0003] The existing boiler scale removal device is relatively simple to clean the inner wall of the boiler, and the cleaning effect is not ideal, which leads to an increase in the frequency of cleaning and affects the normal use and production efficiency of the boiler.

[0004] On this basis, we propose an automatic blowdown system for steam boilers. Utility Model Content

[0008] Furthermore, a ladder is provided on one side of the furnace body, and the ladder extends to the top of the furnace body.

[0009] Furthermore, in order to be able to heat the furnace body and control other operations, a control device is provided on one side of the ignition assembly.

[0010] Furthermore, in order to facilitate timely discharge of the cleaned dirt from the furnace body, a sewage outlet is provided at one end of the furnace body.

[0011] Furthermore, a sliding block is provided on one side of the rotating assembly, and the sliding block is located in a sliding groove provided on the inner wall of the furnace body.

[0012] Furthermore, in order to thoroughly clean the furnace body, several rotating shafts are provided along the center line of the furnace body, preferably 4 or 6.

[0013] Furthermore, the dirt cleaning assembly adopts a sleeve and a rotating shaft, including a guide rod and a cleaning cone, the guide rod is an I-shaped structure, the cleaning cone is sleeved on the outside of the guide rod, a support plate is provided inside the cleaning cone, a telescopic spring is provided at the bottom of the support plate, one end of the telescopic spring is fixed to the bottom of the support plate, and the other end of the telescopic spring is fixed to the protrusion at the bottom of the guide rod.

[0014] In summary, due to the adoption of the above technical solution, the beneficial technical effects of the utility model are:

[0015] An automatic sewage discharge system for a steam boiler, when working, a driving component drives the active gear to rotate, the active gear rotates and drives the rotating component to rotate, the rotating component drives the rotating shaft to rotate and makes the dirt cleaning component rotate along the inner wall of the furnace body, during the rotation of the dirt cleaning component, since the top of the dirt cleaning component is infinitely close to the inner wall of the furnace body, once there is dirt remaining on the inner wall of the furnace body, the dirt cleaning component will exert a certain force on the dirt to make the dirt fall off. The setting of the rotating component greatly improves the dirt cleaning ability of the entire device.

[0016] In addition, an automatic sewage discharge system for steam boilers uses a guide rod, a cleaning cone, and a telescopic spring to effectively prevent the dirt cleaning component from damaging the inner wall of the furnace body. The combination of the guide rod, the cleaning cone, and the telescopic spring effectively prevents the problem of excessive force of the dirt cleaning component causing damage to the inner wall of the entire furnace body.

During operation, the driving component 6 drives the active tooth 7 to rotate, and the active tooth 7 drives the rotating component 8 to rotate at the same time. The rotating component 8 drives the rotating shaft 11 to rotate and makes the dirt cleaning component 12 rotate along the inner wall of the furnace body 1. During the rotation of the dirt cleaning component 12, since the top of the dirt cleaning component 12 is infinitely close to the inner wall of the furnace body 1, once there is dirt remaining on the inner wall of the furnace body 1, the dirt cleaning component 12 will exert a certain force on the dirt to make the dirt fall off.

[0027] A ladder 5 is provided on one side of the furnace body 1, and the ladder 5 extends to the top of the furnace body 1. In order to be able to heat the furnace body 1 and control other operations, a control device 14 is provided on one side of the ignition assembly 4.

[0028] In order to conveniently discharge the cleaned dirt from the furnace body 1 in time, a sewage outlet 13 is provided at one end of the furnace body 1. Furthermore, a slider 10 is provided on one side of the rotating assembly 8, and the slider 10 is located in a slide groove 9 provided on the inner wall of the furnace body 1. In order to thoroughly clean the furnace body 1, several rotating shafts 11 are provided along the center line of the furnace body 1, preferably 4 or 6.

[0029] Example 2

[0030] In this embodiment, an automatic sewage discharge system for a steam boiler further includes: the dirt cleaning assembly 12 is sleeved with the rotating shaft 11 by a sleeve, including a guide rod 16 and a cleaning cone 17, the guide rod 16 is an I-shaped structure, the cleaning cone 17 is sleeved on the outside of the guide rod 16, a support plate 18 is provided inside the cleaning cone 17, a telescopic spring 19 is provided at the bottom of the support plate 18, one end of the telescopic spring 19 is fixed to the bottom of the support plate 18, and the other end of the telescopic spring 19 is fixed to the protrusion 20 at the bottom of the guide rod 16. The cooperation of the guide rod 16, the cleaning cone 17 and the telescopic spring 19 can effectively prevent the dirt cleaning assembly 12 from damaging the inner wall of the furnace body 1. During the cleaning process, once there is dirt that cannot be cleaned once, the excessive force of the dirt cleaning assembly 12 will cause damage to the inner wall of the entire furnace body 1. For this reason, we propose the above solution.
