Description

Technical Field

[0001] This utility model relates to the field of boiler heating technology, specifically to a multi-level power adjustable electrode boiler device. Background Technology

[0002] With increasingly stringent national environmental protection policies, the boiler industry has an increasingly urgent need for energy-saving and environmentally friendly equipment. High-pressure electrode boilers, as a clean energy heating device, are widely used in heating, production and other fields.

[0003] Currently, existing high-pressure electrode boilers are mainly divided into two types: submerged and jet-type. Their power regulation methods mostly rely on adjusting the contact area between the zero electrode and the phase electrode or adjusting the water level.

[0004] However, this type of adjustment method has obvious limitations: on the one hand, the power adjustment range is narrow, and the minimum load usually needs to be maintained at around 40%, which easily leads to energy waste; on the other hand, the overall height of the furnace body is relatively high, occupying a large space, and the complex structure results in high manufacturing and maintenance costs. In addition, the electrode installation stability of the existing device is insufficient, and it is prone to displacement during sliding adjustment, affecting the power adjustment accuracy and equipment safety. Utility Model Content

[0005] The purpose of this invention is to provide a multi-level power adjustable electrode boiler device, which effectively solves the technical problems of narrow power adjustment range, complex structure and insufficient adjustment stability of existing high-pressure electrode boilers.

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

[0007] A multi-stage power adjustable electrode boiler device includes a shell, an inlet pipe and an outlet pipe on the shell, a first support plate and a second support plate slidably disposed inside the shell, the first support plate being located above the second support plate, a plurality of first electrode units disposed on the first support plate, and second electrode units corresponding to the first electrode units disposed on the second support plate.

[0008] A first drive rod and a second drive rod are respectively provided on the first support plate and the second support plate. The second drive rod extends out of the outer shell after passing through the first support rod. The top ends of the first drive rod and the second drive rod are connected to a drive unit. The drive unit drives the first drive rod and the second drive rod to move at the same time, so that the first support plate moves closer to each other or further away from each other.

[0009] Furthermore, the first electrode unit includes an insulating sleeve and a first electrode fixedly disposed within the insulating sleeve. The insulating sleeve is fixedly mounted on the first support plate, and the upper end of the insulating sleeve is slidably sealed to the outer shell. The second electrode unit includes a second electrode, which is fixedly disposed on the second support plate.

[0010] Furthermore, the first electrode is the phase electrode, and the second electrode is the zero electrode.

[0011] Furthermore, a guide rod is provided inside the outer casing, and the first support plate and the second support plate are slidably mounted on the guide rod.

[0012] Furthermore, the drive unit includes a rack, a gear, and a drive motor. The rack is provided on the upper end of both the first drive rod and the second drive rod. The drive motor is connected to the gear, and the gear meshes with the rack provided on the first drive rod and the second drive rod.

[0013] Furthermore, the drive unit also includes a support frame, which is fixedly mounted on the housing, and the drive motor is fixedly mounted on the support frame.

[0014] Furthermore, the first drive rod and the second drive rod are slidably and sealingly connected to the housing.

[0015] Furthermore, the inner wall of the insulating sleeve is provided with a high-temperature resistant insulating coating, which is made of nano-alumina or boron nitride material.

[0016] Furthermore, several first electrode units are arranged radially and uniformly along the central axis of the first support plate, with equal included angles between two adjacent first electrode units, and corresponding second electrode units are arranged radially on the second support plate simultaneously.

[0017] Furthermore, the inner wall of the outer shell is provided with a guide groove, and the edges of the first support plate and the second support plate are respectively provided with sliders adapted to the guide groove, and the sliders are slidably embedded in the guide groove.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention adjusts the distance between the first and second electrode units by sliding a first and second support plate within the outer casing and driving them closer or further apart via a drive unit. Based on the relationship between the water resistance between the electrodes and the distance, a smaller distance results in higher power, and a larger distance results in lower power. This invention overcomes the limitations of traditional adjustment methods, offering a wider power adjustment range. Furthermore, the sliding design of the double support plates significantly reduces the overall height of the furnace body, minimizing space occupation, and the structure is simple and easy to manufacture.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1

[0033] See Figure 1 and Figure 2 This embodiment discloses a multi-level power adjustable electrode boiler device, including a shell 101. A water inlet pipe 102 is provided on the lower left side of the shell 101, and a water outlet pipe 103 is provided on the upper right side. Four guide rods are vertically arranged inside the shell 101. The top end of the guide rods is fixedly connected to the inner wall of the top of the shell 101, and the bottom end is fixedly connected to the inner wall of the bottom of the shell 101. A first support plate 104 and a second support plate 105 are slidably arranged inside the shell 101. The first support plate 104 is located above the second support plate 105, and both the first support plate 104 and the second support plate 105 are slidably sleeved on the four guide rods.

[0034] As an alternative, in actual use, the inner wall of the outer casing 101 is provided with four guide grooves along the vertical direction, and the edges of the first support plate 104 and the second support plate 105 are respectively provided with sliders that are adapted to the guide grooves, and the sliders slide into the guide grooves.

[0035] Furthermore, three first electrode 112 units 106 are radially and evenly arranged on the first support plate 104 along its central axis, with an included angle of 120° between two adjacent first electrode 112 units 106. The first electrode 112 unit 106 includes an insulating sleeve 111 and a first electrode 112 fixedly disposed inside the insulating sleeve 111. The first electrode 112 is a phase electrode. The insulating sleeve 111 is fixedly mounted on the first support plate 104. The inner wall of the insulating sleeve 111 is coated with a nano-alumina high-temperature resistant insulating coating with a thickness of 0.1 mm. The upper end of the insulating sleeve 111 is slidably and sealed to the top of the outer shell 101 through a sealing ring.

[0036] The second support plate 105 is provided with three second electrode units 107 that correspond one-to-one with the first electrode unit 106. The second electrode unit 107 is the second electrode, which is the zero electrode. The second electrode is fixedly mounted on the second support plate 105 and is precisely aligned with the first electrode 112 in the vertical direction.

[0037] A first support plate 104 is connected to a first drive rod 108, and a second support plate 105 is fixedly connected to a second drive rod 109. The second drive rod 109 extends out of the top of the outer casing 101 after passing through a through hole provided on the first support plate 104. A drive unit 110 is connected to the top of the first drive rod 108 and the second drive rod 109. The drive unit 110 includes a rack 113, a gear 114, a drive motor 115, and a support frame 116. The support frame 116 is fixed to the top of the outer casing 101, and the drive motor 115 is fixedly mounted on the support frame 116. The output shaft of the drive motor 115 is connected to the gear 114. A rack 113 is provided at the upper end of both the first drive rod 108 and the second drive rod 109, and the gear 114 meshes with both racks 113 simultaneously. The penetration points of the first drive rod 108 and the second drive rod 109 with the top of the outer casing 101 are slidably sealed by a mechanical seal.

[0038] In this embodiment, the forward rotation of the drive motor 115 drives the gear 114 to rotate, causing the first drive rod 108 to move upward and the second drive rod 109 to move downward, so that the first support plate 104 and the second support plate 105 move away from each other, the electrode spacing increases from the initial 5cm to 15cm, and the power decreases from 100% to 10%; when the drive motor 115 reverses, the first support plate 104 and the second support plate 105 move closer to each other, the spacing decreases from 15cm to 5cm, and the power increases from 10% to 100%.

[0039] Example 2

[0040] This Embodiment 1 is basically the same, except that 4 first electrode units 106 are evenly arranged radially along the central axis on the first support plate 104, and the included angle between two adjacent first electrode units 106 is 90°; a boron nitride high-temperature resistant insulating coating is coated on the inner side wall of the insulating sleeve 111 with a thickness of 0.15 mm; 2 guide rods are arranged vertically in the outer shell 101.

[0041] Embodiment 3

[0042] This embodiment is basically the same as Embodiment 1, except that 5 first electrode units 106 are evenly arranged radially along the central axis on the first support plate 104, and the included angle between two adjacent first electrode units 106 is 72°; a high-temperature resistant insulating coating mixed with nano-aluminum oxide and boron nitride is coated on the inner side wall of the insulating sleeve 111 with a thickness of 0.2 mm; the drive motor 115 uses a servo motor and can precisely control the rotation angle.

[0043] Further, in some preferred embodiments, a position detection module and a controller are further included; a magnetic grating ruler is arranged at the top end of the outer shell 101, and Hall sensors cooperating with the magnetic grating ruler are respectively installed on the first drive rod 108 and the second drive rod 109; the Hall sensors and the drive motor are both electrically connected to the controller, and the controller adjusts the electrode spacing in real time according to a preset power and displacement mapping table. It breaks through the limitation of the traditional mechanical adjustment accuracy. The nanoscale closed-loop feedback of the electrode plate displacement is realized through the magnetic grating ruler and the Hall sensor, and the mechanical error is automatically compensated in combination with the preset mapping table to ensure the accuracy and repeatability of multi-stage power switching, especially suitable for frequent power adjustment scenarios.

[0044] Further, a bellows seal section is extended and arranged at the top of the insulating sleeve 11, and the upper end of the bellows seal section is fixedly connected to the top wall of the outer shell; an inert gas is filled inside the bellows seal section, and a pressure sensor is embedded on its side wall; the pressure sensor is communicatively connected to an external alarm. The bellows structure maintains the sealing performance during the movement of the electrode, and the internal inert gas forms a second insulating barrier; the pressure sensor monitors the gas leakage in real time and triggers an alarm before the insulating sleeve coating is damaged, eliminating the risk of high-voltage breakdown.

Therefore, the appended claims are intended to be interpreted to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. It should be noted that any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
