Technical Field

[0001] The utility model relates to the technical field of water storage for preventing dry burning, in particular to a water storage device for preventing dry burning of a boiler. Background Art

[0002] During the use of the boiler, the water in the boiler will turn into steam and generate heat as the boiler heats up, which reduces the amount of water in the boiler. Modern boilers usually use a make-up water pump to replenish water in the boiler to avoid the problem of dry burning of the boiler. The current anti-dry burning device mainly uses automatic control of the make-up water pump. The make-up water pump switch is controlled according to the water level in the boiler, and water is drawn from the outside to replenish the water level in the boiler. However, this water replenishment method requires circuit control during the water replenishment process, and the water level needs to be monitored during control. There are too many detection components, resulting in excessive maintenance costs and a lot of workload. In view of this, in-depth research on the above-mentioned problems led to the creation of this case. Utility Model Content

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] See also Figure 1-3The utility model provides an implementation scheme: a boiler anti-dry burning water storage device, the support and installation body of the equipment is a boiler body 1, the boiler body 1 is a vertical kettle-type shell, a support frame 2 is welded on one side of the boiler body 1, a water storage tank 3 is fixed by the support frame 2, and a water storage pipe 4 at the bottom of the water storage tank 3 is connected to a liquid level recovery pipe 5 as a water replenishment channel;

[0021] According to the instruction manual Figure 1-3 It can be seen that a sealing seat 6 is provided at the inner end of the liquid level recovery tube 5. The sealing seat 6 and the sealing piece 7 adopt a plug-in structure. The posture control of the sealing piece 7 is completed by a guide rod 8. The guide rod 8 is inserted in a guide ring 9, and the guide ring 9 is fixed in the boiler body 1. Under the buoyancy of water, a number of buoyancy plates 10 on the guide rod 8 support the sealing piece 7 on the guide rod 8 and seal it on the sealing seat 6 to restore the liquid level recovery tube 5. A control magnetic block 11 is provided at the bottom end of the guide rod 8. When the water level in the boiler body 1 drops, the water level in the corresponding guide ring 9 also drops accordingly. At this time, the buoyancy of the buoyancy plate 10 drops. When the water level drops to a certain level, multiple buoyancy plates 10 are exposed to the water level. At this time, under the action of gravity, the guide rod 8 and the control magnetic block 11 move downward to open the blockage. Plate 7, as the control magnet 11 is getting closer and closer to the magnetic seat 12, at this time, under the attraction of the magnetic seat 12, the suction force between the control magnet 11 and the magnetic seat 12 is further increased, so that after water replenishment, the guide rod 8 will not be immediately reset due to the buoyancy of the buoyancy plate 10 immersed in the water. Only when all the buoyancy plates 10 are fully immersed in the water, that is, after the water is replenished to the specified water level, the buoyancy of the buoyancy plate 10 is greater than the gravity of the counterweight on the guide rod 8 and the suction force of the control magnet 11, the guide rod 8 will push the blocking plate 7 to reset the blocking plate 7 and block it on the blocking seat 6. Different from the existing electrically controlled boiler water level control system, it avoids the problem of complex signal source feedback control of the circuit control system, and completes the switching of the water replenishment passage through the control of buoyancy and magnetism.

[0022] As a preferred solution, further, the blocking seat 6 is a rectangular plate and a slide groove matching the blocking piece 7 is provided on the blocking seat 6. At least one pair of reset springs 14 are provided on the blocking seat 6 and connected to the blocking piece 7 to facilitate the reset of the blocking piece 7.

[0023] As a preferred solution, further, both ends of the control magnet 11 are partially conical structures and the top of the magnetic seat 12 is provided with a buffer layer 15 matching the shape of the control magnet 11 to avoid collision between the control magnet 11 and the magnetic seat 12.

[0024] As a preferred solution, further, the liquid level recovery pipe 5 is connected to the end of the water storage pipe 4 through a pair of matching flanges, and the pair of flange connections facilitate the disassembly and assembly of the water storage and replenishment pipe and the water storage pipe 4.

[0025] As a preferred solution, further, a siphon type liquid level monitor 16 is connected to one side of the boiler body 1, and the liquid level monitor is located below the safe water level of the guide rod 8, and is used to further monitor the water level in the boiler body 1 to avoid excessive drop in the water level.

[0026] As a preferred solution, further, a control water supply pipe 17 is connected to one side of the boiler body 1, and the control water supply pipe 17 is connected to an external water supply pump 18, and the water supply pump 18 and the control water supply pipe 17 further serve as a safety water supply pipeline.

[0027] From the above, it can be generally known that the boiler anti-dry burning water storage device adopts a series-connected buoyancy plate 10 as a control device of the guide rod 8, and uses the guide rod 8 to block the water supply pipeline. When the water level drops to a certain level, gravity and magnetic attraction are used to make the guide rod 8 open the water supply pipeline. When the water is replenished to the specified water level, the buoyancy plate 10 will push the guide rod 8 to re-block the water supply pipeline due to the buoyancy. The control is simple and the maintenance is convenient.

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