A connecting pipe is fixedly connected to the outer edge of the boiler body, and a support rod is fixedly installed on the inner wall of the connecting pipe. A ceramic filter element layer is installed on one side of the support rod. By setting an ultrafiltration membrane layer, a reverse osmosis membrane layer, and a ceramic filter element layer, water is filtered to ensure the cleanliness of the water entering the boiler body. Simultaneously, the connecting bolts of the connecting pipe and the connecting tube can be removed, allowing the abutment ring to be removed from the outer wall of the ultrafiltration membrane layer.

When receiving a start-up command and peak-shaving power from the DCS, if a boiler body malfunction is detected during self-checking, it is reported to the DCS, and the power of the malfunctioning boiler is subtracted from the total power of the heating network, preparing the boiler body for start-up.

Description

Technical Field

[0001] This application relates to the field of boiler technology, and in particular to an electrode electric thermal storage peak-shaving electric boiler. Background Technology

[0002] An electric boiler, also known as an electric heating boiler or electric thermal boiler, is a boiler equipment that uses electricity as its energy source and converts it into heat energy. After being converted by the boiler, it outputs steam, high-temperature water, or organic heat carrier with a certain amount of heat energy. There are three heating methods for electric boilers: electromagnetic induction heating, resistance (electric heating tube) PTC ceramic semiconductor heating, and resistance heating. Resistance heating is further divided into stainless steel heating tube electric boilers and ceramic heating tube electric boilers. Resistance heating uses resistance tubular electric heating elements, while semiconductor heating uses oxide semiconductor ceramic sheets. Water and electricity are completely separated.

[0003] The published patent CN217929237U describes a high-voltage electrode electric thermal storage peak-shaving electric boiler, comprising a furnace body with a fixed frame at the bottom. A servo motor is mounted at the bottom of the fixed frame, and a screw is connected to the output end of the servo motor. A threaded sleeve is threaded onto the screw, and a movable support plate is movably connected to the threaded sleeve via a rotating shaft. The other end of the movable support plate is movably connected to a support plate via a rotating shaft. A purification box is fixedly installed on the outer wall of the furnace body, and the purification box has an inlet main pipe and an outlet main pipe. An installation assembly is installed inside the purification box, and a purification screen is installed on the installation assembly. A water pump is installed on the pipeline connecting the purification box and the furnace body. This invention uses threaded transmission and is driven by a servo motor to make the support plate gradually slide outward on the placement surface, effectively increasing the bottom support area of ​​the equipment. By setting a purification screen in the purification box, this invention can perform multiple filtrations on the flowing water, effectively improving water quality.

[0004] When the above devices are implemented, the water flow is filtered through the purification screen to improve the water quality. However, after long-term use, it is not convenient to disassemble and remove the purification screen, which makes it difficult to clean and maintain the device and further affects the water flow. Therefore, this application proposes an electrode electric thermal storage peak-shaving electric boiler. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an electrode electric thermal storage peak-shaving electric boiler, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: an electrode electric thermal storage peak-shaving electric boiler, comprising a furnace body and a placement plate, wherein a connecting pipe is fixedly connected to the outer edge of the furnace body via a flange, a support rod is fixedly installed on the inner wall of the connecting pipe, a ceramic filter element layer is installed on one side of the support rod, a reverse osmosis membrane layer is installed on the side of the ceramic filter element layer away from the support rod, an ultrafiltration membrane layer is installed on the side of the reverse osmosis membrane layer away from the ceramic filter element layer, a connecting pipe is also installed on the outer side of the connecting pipe via a flange, a insertion tube is installed on the side of the connecting pipe near the connecting pipe, and one end of a plurality of push springs is fixedly connected to the other side of the insertion tube, and the other end of the plurality of push springs is fixedly connected to an abutment ring; Furthermore, upon receiving a stop peak-shaving command, the boiler will stop operating according to the set shutdown procedure; Simultaneously, it continuously monitors whether it receives a heat storage command from the heat storage tank, which is used for heat network coupling when the boiler is stopped: When a heat storage command is received, the heat storage tank starts storing heat. At the same time, it checks whether the heat storage tank is full. If it is full but no stop heat storage command has been received, it notifies the DCS that the heat storage tank is full and can no longer store heat. If the heat storage tank is not full, it will continue to store heat until a stop heat storage command is received, at which point the heat storage tank will stop storing heat.

[0007] In a preferred embodiment, an exhaust pipe is fixedly connected to the inner wall of the furnace body, a control valve is rotatably installed on the inner wall of the exhaust pipe, and a pressure gauge is installed on the outer edge of the furnace body.

[0008] By adopting the above technical solution, the gas pressure inside the furnace can be monitored in real time using a pressure gauge, and the gas inside the furnace can be discharged to the outside through the exhaust pipe by opening the control valve to relieve pressure.

[0009] In a preferred embodiment, four uprights are fixedly installed along the outer edge of the furnace body, and the bottom of each of the four uprights is fixedly connected to the top of the placement plate.

[0010] By adopting the above technical solution, a stable support can be formed for the device, ensuring its stability when placed on the ground.

[0011] In a preferred embodiment, the outer diameters of the insertion tube and the abutment ring are both adapted to the inner wall diameter of the connecting tube, and the side of the abutment ring away from the push spring is in contact with the side of the ultrafiltration membrane layer away from the reverse osmosis membrane layer.

[0012] By adopting the above technical solution, the contact ring can be used to abut against the ultrafiltration membrane layer, ensuring that the ultrafiltration membrane layer will not easily shift its position when in contact with the water flow. This ensures that the ultrafiltration membrane layer is stably installed inside the connecting pipe, effectively cooperating with the reverse osmosis membrane layer and the ceramic filter element layer to filter the water flow entering the furnace.

[0013] In a preferred embodiment, the placement plate has a square groove inside, and an electric push rod is fixedly installed on the inner wall of the square groove. The output shaft of the electric push rod is fixedly connected to a stabilizing plate.

[0014] By adopting the above technical solution, the driveable electric push rod can move the stabilizing plate to slide on the inner wall of the square groove, thereby moving the stabilizing plate to the outside and making contact with the ground to support the placement plate and ensure stability.

[0015] In a preferred embodiment, a positioning plate is installed on the inner wall of the square groove, the output shaft of the square groove is slidably connected to the inner wall of the positioning plate, one end of a return spring is fixedly connected to one side of the positioning plate, and the other end of the return spring is fixedly connected to a stabilizing plate.

[0016] By adopting the above technical solution, the stabilizing plate can be quickly returned to its original position by means of the elastic restoring force of the return spring, which ensures the efficiency when returning to the original position. In addition, the positioning plate can be used to provide a fulcrum for the output shaft of the electric push rod, ensuring its stability when it is stable.

[0017] In a preferred embodiment, the stabilizing plate is slidably connected to the inner wall of the square groove, and the bottom of the side of the stabilizing plate away from the positioning plate is on the same plane as the bottom of the placement plate.

[0018] By adopting the above technical solution, moving the stabilizing plate to the outside can effectively increase the contact area between the placement plate and the outside, thereby ensuring stability.

[0019] The beneficial effects of this application are: This type of electrode electric thermal storage peak-shaving electric boiler filters water by setting up an ultrafiltration membrane layer, a reverse osmosis membrane layer, and a ceramic filter element layer to ensure the cleanliness of the water entering the boiler body. At the same time, the connecting bolts of the connecting pipe and the connecting tube can be removed, and the abutment ring can be removed from the outer wall of the ultrafiltration membrane layer, thereby releasing the positioning of the ultrafiltration membrane layer. This allows the ceramic filter element layer, reverse osmosis membrane layer, and ultrafiltration membrane layer to be easily removed from the outside for cleaning and maintenance, ensuring water flow. Furthermore, the two flanges can be moved to directly remove the connecting pipe, making disassembly even easier.

[0020] This electrode electric thermal storage peak-shaving electric boiler uses an electric push rod to move a stabilizing plate along the inner wall of a square groove, thereby moving the stabilizing plate to the outside and into contact with the ground. This increases the contact area between the plate and the ground, providing support and ensuring stability. Simultaneously, the elastic return force of the return spring can pull the stabilizing plate back to its original position quickly, ensuring efficiency when returning to the correct position.

A connecting pipe 12 is also installed on the outer side of the connecting pipe 7 via a flange 21. A side of the insertion pipe 13 is installed on the side of the connecting pipe 12 close to the connecting pipe 7. One end of a plurality of push springs 14 is fixedly connected to the other side of the insertion pipe 13, and an abutment ring 15 is fixedly connected to the other end of the plurality of push springs 14.

[0025] See Figure 1 and Figure 2 An exhaust pipe 3 is fixedly connected to the inner wall of the furnace body 1. A control valve 4 is rotatably installed on the inner wall of the exhaust pipe 3. A pressure gauge 2 is installed on the outer edge of the furnace body 1, so that the pressure gauge 2 can be used to monitor the gas pressure inside the furnace body 1 in real time, and the control valve 4 can be opened to release the gas inside the furnace body 1 to the outside through the exhaust pipe 3 to achieve pressure relief.

[0026] See Figure 1 and Figure 2Four uprights 5 are fixedly installed on the outer edge of the furnace body 1, and the bottom of the four uprights 5 are fixedly connected to the top of the placement plate 6, so as to form a stable support for the device and ensure its stability when placed on the ground.

[0027] See Figure 2 - Figure 4 The outer diameters of the insertion tube 13 and the abutment ring 15 are both adapted to the inner diameter of the connecting tube 7. The side of the abutment ring 15 away from the push spring 14 is in contact with the side of the ultrafiltration membrane layer 11 away from the reverse osmosis membrane layer 10, so that the abutment ring 15 can be used to abut the ultrafiltration membrane layer 11, ensuring that the ultrafiltration membrane layer 11 will not easily shift its position when in contact with the water flow, thereby ensuring that the ultrafiltration membrane layer 11 is stably set inside the connecting tube 7, effectively cooperating with the reverse osmosis membrane layer 10 and the ceramic filter element layer 9 to filter the water flow entering the furnace body 1.

[0028] See Figure 5 The placement plate 6 has a square groove 16 inside. An electric push rod 17 is fixedly installed on the inner wall of the square groove 16. The output shaft of the electric push rod 17 is fixedly connected to a stabilizing plate 18, so that the electric push rod 17 can be driven to slide the stabilizing plate 18 on the inner wall of the square groove 16, thereby moving the stabilizing plate 18 to the outside and making contact with the ground to support the placement plate 6 and ensure stability.

The bottom of the side of the stabilizing plate 18 away from the positioning plate 19 is on the same plane as the bottom of the placement plate 6, so that the stabilizing plate 18 can effectively increase the contact area between the placement plate 6 and the outside by moving to the outside, thereby ensuring stability.

[0031] Working principle: When the start command and peak power given by the DCS are received, the self-check is performed first. If a fault is found in furnace body 1, it is reported to the DCS. At the same time, the power of the faulty furnace body 1 is subtracted from the total power of the heating network. Furnace body 1 is ready to start. The load of furnace body 1 in the West Network, South Network and North Network is allocated by the power plant according to the DCS command and the operating status of the heating network. Each heating network starts furnace body 1 according to the allocated power and start priority. First, external water can be discharged into the furnace body 1 through the connecting pipe 7 via the connecting pipe 12. Then, the water can be filtered through the ultrafiltration membrane layer 11, the reverse osmosis membrane layer 10, and the ceramic filter element layer 9 to ensure the cleanliness of the water entering the furnace body 1. At the same time, the connecting bolts of the connecting pipe 7 and the connecting pipe 12 can be removed, and the abutment ring 15 can be removed from the outer wall of the ultrafiltration membrane layer 11, thereby releasing the positioning of the ultrafiltration membrane layer 11. Then, the ceramic filter element layer 9, the reverse osmosis membrane layer 10, and the ultrafiltration membrane layer 11 can be easily removed to the outside for cleaning and maintenance. At the same time, the electric push rod 17 can be driven to move the stabilizing plate 18 to slide on the inner wall of the square groove 16, thereby moving the stabilizing plate 18 to the outside and into contact with the ground, providing support for the placement plate 6 and ensuring stability. At the same time, the elastic reset force of the reset spring 20 can be used to pull the stabilizing plate 18 back to its original position quickly, ensuring efficiency in returning to the original position.
