Description

Technical Field

[0001] The utility model relates to the field of electrode boilers, in particular to a control system for electrode boilers. Background Art

[0002] The working principle of an electrode boiler is to utilize the high heat resistance characteristic of water to directly convert electrical energy into heat energy and generate steam. This process involves converting electrical energy into heat energy through the resistance of water, thereby heating the boiler water to produce hot water or steam.

[0003] For example, in the patent named Electrode Boiler (patent application number: CN202210378007.1), it is disclosed that the electrode boiler is provided with a collar with a cavity. The presence of the collar plays a transitional role in the movement of the lifting rod, avoiding the situation where the lifting rod instantaneously enters a rapidly heated environment or a rapidly cooled environment, and reducing the probability of cracks in the lifting rod. Moreover, the collar can reduce the ambient temperature around the motor and protect the motor from overheating operation. However, the cavity inside the collar requires the actual input of a temperature-carrying liquid for transition to avoid excessive temperature difference, and additional energy needs to be consumed to provide energy for the input of the liquid.

[0004] Therefore, it is necessary to propose a control system for electrode boilers to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a control system for an electrode boiler to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A control system for an electrode boiler, including a sensing unit, a control unit, an execution unit, and a furnace body. The sensing unit, the control unit, and the execution unit are sequentially connected by signals. The sensing unit includes a first temperature sensor and a second temperature sensor. The control unit includes a controller. The execution unit includes a driving motor;

[0007] A collar is provided at the top of the furnace body. An opening is provided at the top of the collar. The bottom end of the opening communicates with the inside of the furnace body. An upper connecting rod is slidably arranged in the opening. The bottom end of the upper connecting rod extends into the inside of the furnace body. The top end of the opening communicates with a protection cylinder;

[0008] A cavity is provided between the outer side and the inner wall of the collar. A heat preservation liquid is provided inside the cavity. A heat conduction rod is provided inside the cavity. The bottom end of the heat conduction rod passes through the cavity and the passing end extends into the inside of the furnace body. The first temperature sensor is arranged inside the cavity.

[0009] Preferably, the driving motor is fixed outside the protection cylinder. The upper half of the upper connecting rod extends into the interior of the protection cylinder. A sponge ring is arranged inside the protection cylinder. The inner side of the sponge ring fits against the outer side of the extending end of the upper connecting rod. A rack is fixed along the height direction on the upper half of the upper connecting rod. A gear is sleeved on the driving shaft of the driving motor, and the gear meshes with the rack.

[0010] Preferably, the second temperature sensor is arranged inside the furnace body.

[0011] Preferably, the bottom end of the upper connecting rod is connected to a lower connecting rod. A support plate is fixed inside the furnace body. The support plate is arranged below the lower connecting rod.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. During the actual operation of the present utility model, when heat is generated during the operation of the furnace body, the heat will be transferred to the heat preservation liquid inside the cavity through the heat conducting rod, thereby heating the heat preservation liquid. When the upper connecting rod moves inside the ring sleeve, the heat will be transferred to the upper connecting rod, playing a transitional role in the movement of the upper connecting rod, avoiding the upper connecting rod from entering a suddenly hot or cold environment instantaneously. And the heating inside the ring sleeve is driven by the heat generated during the operation of the furnace body. When the heat inside the furnace body increases or decreases, the heat preservation liquid inside the cavity will also change accordingly. And when the furnace body stops working, the heat preservation liquid in the ring sleeve automatically cools with the cooling of the environment, reducing energy consumption and eliminating the need for manual repeated addition of liquid for heating or cooling.

[0016] 2. At the same time, the first temperature sensor can monitor the temperature of the heat preservation liquid, and the second temperature sensor can monitor the temperature inside the furnace body. When it is detected that the temperature inside the furnace body has increased and the heat preservation liquid has reached an appropriate temperature, a signal can be transmitted to the controller, so that the controller controls the driving motor to start, driving the upper connecting rod to move up and down, avoiding excessive temperature difference, which is more accurate compared to manual adjustment.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a control system for an electrode boiler as shown in Figure 1 - Figure 3 The figure, which includes a sensing unit, a control unit, an execution unit, and a furnace body 1. The sensing unit, the control unit, and the execution unit are sequentially connected by signals. The sensing unit monitors the temperature signal and transmits the temperature signal to the control unit. After receiving the signal, the control unit controls the execution unit to work.

[0023] Specifically, the sensing unit includes a first temperature sensor 10 and a second temperature sensor 12, the control unit includes a controller, and the execution unit includes a drive motor 16;

[0024] A ring sleeve 2 is provided at the top of the furnace body 1. A through port 3 is opened at the top of the ring sleeve 2. The bottom end of the through port 3 is communicated with the inside of the furnace body 1. An upper connecting rod 6 is slidably arranged in the through port 3. The bottom end of the upper connecting rod 6 extends into the inside of the furnace body 1. The top end of the through port 3 is communicated with a protection cylinder 5. The drive motor 16 is fixed outside the protection cylinder 5. The upper half of the upper connecting rod 6 extends into the inside of the protection cylinder 5. A sponge ring 17 is arranged inside the protection cylinder 5. The inner side of the sponge ring 17 is in contact with the outer side of the extending end of the upper connecting rod 6. A rack is fixed along the height direction on the upper half of the upper connecting rod 6. A gear is sleeved on the drive shaft of the drive motor 16. The gear meshes with the rack.

[0025] In the actual operation of the present utility model, after the driving motor 16 is started, it drives the gear to rotate. Since the gear meshes with the rack, the upper connecting rod 6 can be driven to complete the upward or downward extending movement through the driving of the gear. At the same time, when the upper connecting rod 6 moves up and down, the outer side of the upper connecting rod 6 will rub against the inner side of the sponge ring 17, which is convenient for cleaning the outer side of the upper connecting rod 6 and improving the cleanliness of the upper connecting rod 6.

[0026] A cavity 8 is formed between the outer side and the inner wall of the ring sleeve 2. A heat preservation liquid 11 is arranged inside the cavity 8, and a heat conducting rod 9 is arranged inside the cavity 8. The bottom end of the heat conducting rod 9 passes through the cavity 8, and the passing end extends into the interior of the furnace body 1. The first temperature sensor 10 is arranged inside the cavity 8, and the second temperature sensor 12 is arranged inside the furnace body 1. The heat preservation liquid 11 can be a liquid such as water.

[0027] In the actual operation of the present utility model, when the furnace body 1 generates heat during operation, the heat will be transferred to the heat preservation liquid 11 inside the cavity 8 through the heat conducting rod 9, thereby causing the heat preservation liquid 11 to heat up, so that the temperature inside the ring sleeve 2 and the temperature inside the furnace body 1 will not differ greatly. When the upper connecting rod 6 moves inside the ring sleeve 2, the heat will be transferred to the upper connecting rod 6, playing a transitional role in the movement of the upper connecting rod 6, avoiding the upper connecting rod 6 from entering a suddenly hot or suddenly cold environment instantaneously, and reducing the probability of cracks appearing on the upper connecting rod 6.

[0028] Moreover, the heating inside the ring sleeve 2 is driven by the heat generated when the furnace body 1 operates. When the heat inside the furnace body 1 rises or falls, the heat preservation liquid 11 inside the cavity 8 will also change accordingly. And when the furnace body 1 stops operating, the heat preservation liquid 11 in the ring sleeve 2 automatically cools down with the cooling of the environment, reducing energy consumption and eliminating the need for manual repeated addition of liquid for heating or cooling.

[0029] At the same time, the first temperature sensor 10 can monitor the temperature of the heat preservation liquid 11, and the second temperature sensor 12 can monitor the temperature inside the furnace body 1. When it is detected that the temperature inside the furnace body 1 has risen and the heat preservation liquid 11 has reached an appropriate temperature, a signal can be transmitted to the controller, so that the controller controls the driving motor 16 to start, and the driving motor 16 drives the upper connecting rod 6 to move up and down, avoiding excessive temperature difference, which is more accurate than manual adjustment.

[0030] The bottom end of the upper connecting rod 6 is connected with a lower connecting rod 7. A support plate 14 is fixed inside the furnace body 1. The support plate 14 is arranged below the lower connecting rod 7. The top end of the support plate 14 is fixedly connected with a support cylinder 15, and the bottom end of the lower connecting rod 7 extends into the interior of the support cylinder 15.

[0031] The support cylinder 15 can keep the downward movement of the lower connecting rod 7 vertical and protect the lower connecting rod 7.

[0032] A discharge port 4 is provided at the bottom end of the furnace body 1, and an input port 13 is provided at the top end of one side of the furnace body 1. Both the input port 13 and the discharge port 4 are communicated with the inside of the furnace body 1.

[0033] The drive shaft of the drive motor 16 extends into the inside of the protection cylinder 5, and the protection cylinder 5 is a closed structure. The protection cylinder 5 is hermetically connected to the through port 3 to protect the upper half of the upper connecting rod 6.
