Description

Technical Field

[0001] The utility model relates to the technical field of boiler coal saving, in particular to a novel energy-saving boiler coal economizer. Background Art

[0002] As a commonly used sintered component in modern times, the main function of a boiler is to provide a combustion space for coal and to heat the water inside the boiler pipe. During the use of existing boilers, a boiler economizer is often required to reduce the loss of coal. As a control component, the main function of the existing boiler economizer is to detect the steam output by the boiler. When the boiler is turned on, the output of coal can be reduced, thereby improving the user experience of the boiler economizer. However, due to the lack of filtering auxiliary components, the existing boiler economizer cannot filter the steam output by the boiler during the use of the economizer, resulting in dust in the steam adhering to the inside of the detection component, thereby affecting the service life of the boiler economizer.

[0003] Compared with the existing boiler economizer, the utility model adds a filtering auxiliary component. During the use of the boiler economizer, the steam delivered to the periphery of the detection component cannot be filtered according to the use needs, thereby prolonging the service life of the boiler economizer.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a new type of energy-saving boiler economizer proposed by the utility model includes a pressure detector 1 and a threaded connection buckle 2. The threaded connection buckle 2 is installed on the back of the pressure detector 1. The pressure detector 1 provides a fixing point for the threaded connection buckle 2, the pressure detection probe 7, the display screen 8 and the first connecting line 9 installed on its outer surface. When the pressure data is transmitted to the inside of the pressure detector 1 via the pressure detection probe 7, the pressure detector 1 transmits the pressure data to the inside of the display screen 8. When the pressure data transmitted to the inside of the pressure detector 1 by the pressure detection probe 7 is too large, the resistance value of the varistor inside the pressure detector 1 changes, and the electrical signal is transmitted to the inside of the first connecting line 9. The threaded connection buckle 2 is the threaded connection buckle 2 on its outer surface. The threaded delivery pipe 3 provides a fixing point and facilitates the disassembly of the pressure detector 1; the outer surface of the threaded connection buckle 2 is threadedly connected to the delivery pipe 3, and the delivery pipe 3 is threadedly connected to the outer surface of the threaded connection buckle 2, providing space for steam to be delivered to the inside and conducted to the outer surface of the pressure detection probe 7, and at the same time providing fixing points for the flange 4, interception net 5 and filter layer 6 installed on its outer surface and inside. The outer surface of the delivery pipe 3 is installed with a flange 4, and the flange 4 is installed to the outer surface of the delivery pipe 3. Before using the device, insert the external bolts into the inside of the flange 4, and insert the external bolts into the inside of the external boiler steam pipe to complete the fixation of the economizer. The back of the pressure detector 1 is installed with a pressure detection probe 7, and the pressure detection probe 7 is located on the inner side of the threaded connector 2, and the pressure detection probe 7 is inserted into the inner side of the delivery pipe 3. When the boiler is turned on, steam is delivered to the periphery of the pressure detection probe 7 via the delivery pipe 3. At this time, the pressure detection probe 7 detects the pressure and delivers the detection data to the inside of the pressure detector 1. A display screen 8 is installed on the front of the pressure detector 1. When the detection data is delivered to the inside of the display screen 8, the display screen 8 displays the pressure data. A first connecting line 9 is installed at the bottom of the pressure detector 1. When the electrical signal is transmitted to the inside of the first connecting line 9 via the pressure detector 1, the first connecting line 9 delivers the electrical signal to the inside of the electromagnetic relay 10. The tail end of the first connecting line 9 is equipped with an electromagnetic relay Device 10, when the electrical signal is transmitted to the inside of the electromagnetic relay 10, the electromagnetic relay 10 changes direction and transmits the electrical energy to the inside of the second connecting wire 11. The second connecting wire 11 is installed on one side of the electromagnetic relay 10. When the electrical energy is transmitted to the inside of the second connecting wire 11 via the electromagnetic relay 10, the second connecting wire 11 transmits the electrical energy to the inside of the connecting plug 12. The tail end of the second connecting wire 11 is installed with a connecting plug 12. Before using the device, the connecting plug 12 is inserted into the inside of the external coal output control component. When the electrical energy is transmitted to the inside of the connecting plug 12 via the second connecting wire 11, the connecting plug 12 transmits the electrical energy to the inside of the external output control component, thereby completing the control and saving of coal.

[0022] The working principle of a new energy-saving boiler economizer based on Example 1 is: first, the external bolts are inserted into the interior of the flange 4, and the external bolts are inserted into the interior of the external boiler steam pipe to complete the fixation of the economizer, and then the connecting plug 12 is inserted into the interior of the external coal output control component, and the steam is transported to the periphery of the pressure detection probe 7 via the delivery pipe 3. At this time, the pressure detection probe 7 detects the pressure and transmits the detection data to the interior of the pressure detector 1. The resistance value of the varistor inside the pressure detector 1 changes, and the electrical signal is transmitted to the interior of the first connecting line 9. The first connecting line 9 transmits the electrical signal to the interior of the electromagnetic relay 10. The electromagnetic relay 10 reverses and transmits electrical energy to the interior of the second connecting line 11. The second connecting line 11 transmits electrical energy to the interior of the connecting plug 12. The connecting plug 12 transmits electrical energy to the interior of the external output control component, thereby completing the control and saving of coal.
