Description

Technical Field

[0001] This utility model belongs to the field of electric boiler technology, specifically, it relates to a composite high-voltage solid thermal storage electric boiler. Background Technology

[0002] An electric boiler, also known as an electric heating boiler or electric thermal boiler, is, as the name suggests, a boiler device that uses electricity as its energy source and converts it into heat energy, which is then converted by the boiler to output steam, high-temperature water, or organic heat carrier with a certain amount of heat energy.

[0003] For example, patent application number 202322449721.8, entitled "A Utility Model Patent for a Solid Thermal Storage Electric Boiler," discloses a solid thermal storage electric boiler, including a boiler housing. A door is movably installed on the front side of the boiler housing. A spring, connecting plate, pressure plate, and pad are provided. Before placing the solid thermal storage brick on top of the two pads, the two connecting plates are pulled, causing them to move their corresponding pressure plates. Simultaneously, the connecting plates stretch the springs inside the side grooves. Then, the solid thermal storage brick is placed on top of the two pads, and the connecting plates are released, allowing the two connecting plates to reset under the elastic force of their corresponding springs, thus resetting the pressure plates. The reset pressure plates press against the front side of the solid thermal storage brick, cooperating with the boiler housing to fix the solid thermal storage brick in place. This prevents the solid thermal storage brick from shaking or colliding during subsequent operation, ensuring its service life and preventing damage.

[0004] The aforementioned patent addresses the issue that, due to the high-temperature environment inside the electric boiler and the fact that the springs are located inside the housing, their performance may be affected by prolonged exposure to high temperatures. This could lead to reduced elasticity or fatigue failure, resulting in insufficient clamping force to stably fix the solid heat storage bricks. Consequently, the solid heat storage bricks are prone to shaking and collisions during use, affecting the normal operation and service life of the equipment. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a composite high-voltage solid thermal storage electric boiler that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A composite high-voltage solid thermal storage electric boiler includes a furnace cabinet and further comprises: an installation cavity disposed within the furnace cabinet; multiple support plates equidistantly fixedly connected to the inner wall of the installation cavity; solid thermal storage bricks placed on the support plates; a connecting rod slidably connected within the installation cavity, wherein multiple fixing blocks cooperating with the support plates are equidistantly fixedly connected to the connecting rod, the fixing blocks abutting against the solid thermal storage bricks; a sleeve fixedly connected to the side wall of the furnace cabinet, wherein a piston disc is slidably connected within the sleeve, and one end of the connecting rod penetrating the upper end of the furnace cabinet is fixedly connected to the piston disc; a pressure boosting pipe communicating with the sleeve; and a heat-conducting rod disposed within the installation cavity and penetrating within the sleeve.

[0008] In order to heat the outside of the heating chamber, preferably, the furnace cabinet is provided with a heating chamber, the furnace cabinet is provided with an air outlet, the heating chamber is connected to the installation chamber through the air outlet, a fan is fixedly installed on the side wall of the furnace cabinet, and the output end of the fan is connected to the heating chamber through an air supply pipe.

[0009] In order to ensure that the external gas passing through the heating chamber is fully heated, a plurality of electric heating rods and partition plates are equidistantly arranged inside the heating chamber. The partition plates are staggered and fixedly installed on the inner walls of both sides of the heating chamber, and there is a gap between the partition plates and the inner wall of the heating chamber.

[0010] In order to filter and purify the external gas passing through the fan input, an activated carbon filter element is further included, which is installed inside the fan input.

[0011] To facilitate the inflation and pressurization of the sleeve, and to enable the fixing block to clamp and fix the solid heat storage brick in conjunction with the bearing plate, preferably, a valve switch is also included, which is set on the pressurization pipe.

[0012] In order to keep the air pressure inside the sleeve constant, preferably, a pressure relief pipe is fixedly connected to the sleeve, and a pressure relief valve is provided on the pressure relief pipe.

[0013] In order to enable the piston disc to automatically reset when the gas inside the sleeve is discharged, preferably, a spring is provided inside the sleeve, one end of which is fixedly connected to the inner wall of the lower end of the sleeve, and the other end is fixedly connected to the lower end face of the piston disc.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] This invention, through the cooperation of a pressure boosting pipe, piston disc, connecting rod, and fixing block, can initially fix the solid heat storage brick. The heat-conducting rod conducts heat from the installation cavity to the sleeve, causing the gas inside the sleeve to expand due to heat and increase the gas pressure, further increasing the clamping force of the fixing block on the solid heat storage brick. This effectively improves the fixing stability of the solid heat storage brick during operation, reduces loosening caused by vibration and other factors, and ensures stable operation of the equipment.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] Example 1:

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4A composite high-voltage solid thermal storage electric boiler includes a furnace cabinet 1, and further includes: an installation cavity 101 disposed inside the furnace cabinet 1; multiple support plates 2 equidistantly fixedly connected to the inner wall of the installation cavity 101; solid thermal storage bricks 201 placed on the support plates 2; a connecting rod 402 slidably connected in the installation cavity 101, wherein multiple fixing blocks 403 cooperating with the support plates 2 are equidistantly fixedly connected to the connecting rod 402, and the fixing blocks 403 abut against the solid thermal storage bricks 201; a sleeve 4 fixedly connected to the side wall of the furnace cabinet 1, wherein a piston disc 401 is slidably connected inside the sleeve 4, and one end of the connecting rod 402 passing through the upper end of the furnace cabinet 1 is fixedly connected to the piston disc 401; a pressure boosting pipe 404 communicating with the sleeve 4; and a heat-conducting rod 407 disposed inside the installation cavity 101 and passing through the sleeve 4.

[0024] The furnace cabinet 1 is equipped with a heating chamber 102 and an air outlet 103. The heating chamber 102 is connected to the installation chamber 101 through the air outlet 103. A fan 302 is fixedly installed on the side wall of the furnace cabinet 1. The output end of the fan 302 is connected to the heating chamber 102 through the air supply pipe 303.

[0025] It also includes a valve switch, which is installed on the booster pipe 404.

[0026] It also includes an activated carbon filter element 304, which is installed inside the input end of the blower 302.

[0027] A spring 405 is installed inside the sleeve 4. One end of the spring 405 is fixedly connected to the inner wall of the lower end of the sleeve 4, and the other end is fixedly connected to the lower end face of the piston disc 401.

[0028] In use, open the valve switch on the pressurization pipe 404 to fill the sleeve 4 with gas. The gas pressure pushes the piston disc 401 to slide downward in the sleeve 4, compressing the spring 405 and storing elastic potential energy. The piston disc 401 drives the connecting rod 402 to move downward, and the fixing block 403 on the connecting rod 402 moves downward accordingly, pressing the solid heat storage brick 201 onto the bearing plate 2. When the appropriate fixing pressure is reached, close the valve switch to maintain the pressure inside the sleeve 4 and ensure that the solid heat storage brick 201 is placed stably, which is conducive to heat storage and conduction.

[0029] Then, the fan 302 is started. The outside air is first purified by the activated carbon filter 304. The purified air enters the heating chamber 102 through the air supply pipe 303 for heating. The heated air enters the installation chamber 101 through the air outlet 103 and exchanges heat with the solid heat storage brick 201, transferring heat to the solid heat storage brick 201 for storage. At the same time, the temperature in the installation chamber 101 rises. At this time, the heat conduction rod 407 conducts the heat in the installation chamber 101 to the sleeve 4. The gas in the sleeve 4 expands due to heat, and the air pressure increases. The increased air pressure further pushes the piston disc 401 to move downward. The piston disc 401 drives the connecting rod 402 and the fixing block 403 to apply greater downward pressure, which enhances the clamping and fixing stability of the solid heat storage brick 201 by the fixing block 403 and the bearing plate 2, effectively avoiding the shaking and collision of the solid heat storage brick 201 in subsequent work and ensuring its service life.

[0030] When the solid heat storage brick 201 needs maintenance or replacement, open the valve switch, the gas in the sleeve 4 is discharged, and under the action of the spring 405 restoring its elastic deformation, the spring 405 pushes the piston disc 401 to move upward. The piston disc 401 drives the connecting rod 402 and the fixing block 403 to move upward, releasing the solid heat storage brick 201. Then the solid heat storage brick 201 placed on the support plate 2 can be removed.

[0031] In summary, the heat in the mounting cavity 101 is conducted to the sleeve 4 through the heat-conducting rod 407, causing the gas in the sleeve 4 to expand due to heat, increasing the gas pressure, and thus increasing the clamping force of the fixing block 403 on the solid heat storage brick 201. This effectively improves the fixing stability of the solid heat storage brick 201 during operation, reduces loosening caused by factors such as vibration, and ensures stable operation of the equipment.

[0032] By cleverly utilizing the heat energy within the mounting cavity 101 and converting it into power to enhance the fixing force, the secondary utilization of heat energy is achieved, improving energy utilization efficiency and reducing equipment operating costs.

[0033] By combining spring 405 and valve switch, the fixing block 403 can be easily loosened when the solid heat storage brick 201 needs maintenance or replacement. During normal operation, the fixing effect can be automatically enhanced. The operation process is simple, which improves the maintainability and practicality of the equipment.

[0034] Example 2:

[0035] Reference Figure 1 A composite high-voltage solid thermal storage electric boiler is basically the same as that in Example 1. Furthermore, multiple electric heating rods 3 and partition plates 301 are equidistantly arranged in the heating chamber 102. The multiple partition plates 301 are staggered and are respectively fixedly installed on the inner walls of both sides of the heating chamber 102. There is a gap between the partition plates 301 and the inner wall of the heating chamber 102.

[0036] When the electric heating rod 3 is powered on, it generates heat and heats the air in the heating chamber 102. The air flows under the action of the fan 302. The staggered partition plates 301 cause the air to flow in a tortuous path in the heating chamber 102, thereby prolonging the residence time of the air in the heating chamber 102. This allows the air to fully contact the electric heating rod 3 during the flow process and be fully heated.

[0037] Example 3:

[0038] Reference Figure 3 A composite high-voltage solid thermal storage electric boiler is basically the same as that in Example 1, except that a pressure relief pipe 406 is fixedly connected to the sleeve 4, and a pressure relief valve is provided on the pressure relief pipe 406.

[0039] When the pressure inside the sleeve 4 exceeds the pressure relief value set by the pressure relief valve on the pressure relief pipe 406, the pressure relief valve automatically opens to release pressure. At this time, some of the gas inside the sleeve 4 is discharged through the pressure relief pipe 406, reducing the pressure inside the sleeve 4 to a suitable range. This prevents damage to components such as the piston disc 401 and the sleeve 4 due to excessive pressure, and also ensures the safety of equipment operation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
