Description

Technical Field

[0001] The utility model relates to the technical field of steam boilers, in particular to a water adding device for a steam boiler. Background Art

[0002] After a long period of heating, the internal air pressure of the steam boiler is relatively high, which makes it impossible for conventional water pumps to transport water into the steam boiler. In addition, the temperature difference between the newly added water and the residual water in the boiler is large, which can easily cool the steam and affect the steam discharge.

[0003] According to a Chinese patent document with publication number CN217109521U, a water adding device for a steam boiler is disclosed. A motor, a first bevel gear, and a second bevel gear are used to control the up and down movement of a threaded rod and an extrusion plate, thereby squeezing a water source and causing the water source to flow into a water pipe. The rod and a spring are stretched and retracted to open the first baffle, thereby transporting the water source into the interior of the boiler body and preventing steam from entering the water storage through the water pipe.

[0004] However, when the extrusion plate of the above device squeezes the water in the water tank, it generates a large outward expansion force on the sidewalls of the tank, which can easily cause the water tank to deform. Furthermore, due to the closed structure of the tank, it is impossible to roughly determine the amount of water added from the outside. Therefore, a water adding device for a steam boiler is proposed. Utility Model Content

[0013] The utility model provides a water adding device for a steam boiler, which has the following beneficial effects:

[0014] The utility model heats water through the heating cylinder to avoid a large temperature difference between the added water and the water remaining in the boiler. The water is squeezed by controlling the squeezing plate through the lifting mechanism to press the water in the heating cylinder into the boiler, thereby avoiding the problem that the water pump cannot introduce water due to excessive pressure in the boiler. The water level in the heating cylinder can be roughly judged by the observation rod to ensure that the amount of water added is within the required range. At the same time, the reinforcement plate arranged on the outer surface of the heating cylinder can reinforce the heating cylinder to avoid deformation of the heating cylinder due to the high pressure generated when the squeezing plate squeezes the water.

[0022] Among them, the sealing assembly consists of a sealing plate 13, a telescopic rod 15 and a spring 16. The sealing plate 13 is slidably installed in the slot 12 opened at the end of the water outlet pipe 3. The sealing plate 13 is fixedly connected to the side wall of the water outlet pipe 3 close to the three telescopic rods 15. The three telescopic rods 15 are in a ring array, and the other ends of the three telescopic rods 15 are fixedly connected to the storage hole 14 opened inside the water outlet pipe 3. The outer surface of the telescopic rod 15 is wrapped with a spring 16, and the two ends of the spring 16 are fixedly connected to the inner wall of the storage hole 14 and the sealing plate 13 respectively.

[0023] The spring 16 is always in a stretched state. Under the stretching action of the spring 16 , the sealing plate 13 will be embedded in the card slot 12 , thereby sealing the pipe opening of the water outlet pipe 3 to prevent the steam in the boiler from entering the heating tube 1 .

[0024] Among them, the lifting mechanism consists of a motor 5, an adjusting screw 9, and a guide rod 10. The motor 5 is fixedly installed at the top center position of the heating tube 1. The output shaft of the motor 5 extends to the inside of the heating tube 1 and is fixedly connected to the adjusting screw 9. The other end of the adjusting screw 9 is rotatably connected to the bottom of the inner cavity of the heating tube 1. The adjusting screw 9 passes through the extrusion plate 8 and is connected to the extrusion plate 8 by threaded fitting. Guide rods 10 are respectively provided on both sides of the adjusting screw 9.

[0027] When in use, water is introduced into the heating cylinder 1 through the water inlet pipe 2, and the water is heated by the heating structure at the bottom of the heating cylinder 1. When the water is heated, the motor 5 is started to drive the adjusting screw 9 to rotate. The extrusion plate 8 is restricted by the guide rod 10 and cannot rotate. When the adjusting screw 9 rotates, the extrusion plate 8 will move along the axial direction of the guide rod 10, thereby adjusting the height of the extrusion plate 8. Controlling the extrusion plate 8 to move downward will squeeze the water toward the water outlet pipe 3. The sealing plate 13 at the end of the water outlet pipe 3 will open under the action of water pressure, and further stretch the spring 16, and the sealing plate 13 will open. The heated water will flow into the steam boiler through the outlet, thus completing the water adding operation. After the water adding is completed, the sealing plate 13 will re-block the water outlet pipe 3 under the pull of the spring 16, thereby preventing the steam in the boiler from entering the heating tube 1. In the process of adding water, by observing the extended length of the observation rod 7, the water level in the heating tube 1 can be roughly judged to ensure that the amount of water added is within the required range. At the same time, the reinforcement plate 6 arranged on the outer surface of the heating tube 1 can reinforce the heating tube 1 to prevent the high pressure generated when the squeezing plate 8 squeezes the water from causing deformation of the heating tube 1.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
