Description

Technical Field

[0001] This utility model relates to the field of boiler heating technology, specifically to a device for improving boiler thermal efficiency. Background Technology

[0002] A device for improving boiler thermal efficiency is a device used to enhance thermal efficiency during the boiler heating process. It aims to maximize the utilization rate of the boiler heat source, thereby promoting boiler production capacity. Improving boiler heating efficiency can significantly reduce the operating costs of enterprises.

[0003] Chinese patent CN219889541U discloses a device for improving boiler thermal efficiency. It includes a fixed box, fixedly installed on one side of a biomass boiler; a conveying mechanism rotatably mounted inside the fixed box; a shaking component located at the corner of the conveying mechanism to drive it to shake and flatten the material; a hopper fixedly mounted on the fixed box; a discharge roller rotatably mounted inside the hopper for discharging material; and a discharge chute located below one end of the conveying mechanism for conveying material into the biomass boiler. The discharge roller intermittently discharges material onto a conveyor belt, causing the conveyor belt to oscillate back and forth while rotating, flattening the material and allowing it to flow evenly into the biomass boiler through the discharge chute, thereby improving combustion efficiency and increasing heat production efficiency.

[0004] The above-mentioned device has the effect of fully combusting materials. However, in the operation of existing boilers, the heat source is usually in direct contact with the boiler body, which can easily cause the raw materials inside the boiler to burn. Moreover, when heating large-capacity raw materials, the raw materials on the upper side are far away from the boiler body, which usually results in low heating efficiency. Therefore, it is necessary to provide a device to improve the thermal efficiency of boilers. Utility Model Content

[0005] The purpose of this invention is to provide a device for improving the thermal efficiency of a boiler, thereby solving the problems of raw material scorching and low heat source utilization efficiency caused by existing devices during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for improving boiler thermal efficiency, comprising a boiler base, a boiler body fixedly mounted on the upper part of the boiler base, and a heat-fixing mechanism provided on the lower side of the boiler body; the heat-fixing mechanism includes a support, the support being fixedly mounted inside the boiler base, and an electric telescopic rod being fixedly mounted on the lower part of the support, a support seat being fixedly mounted on the output end of the electric telescopic rod and slidably mounted on the support, a sliding seat being fixedly mounted on the outside of the support seat, and a thermal resistance wire being fixedly mounted inside the support seat.

[0007] Preferably, the support base has an arc-shaped groove inside, which is adapted to the arc-shaped groove of the pot body.

[0008] Preferably, the slide block has several grooves on its outer side, and the slide block is in close contact with the inner wall of the boiler base.

[0009] Preferably, a circulation mechanism is provided between the pot body and the support base. The circulation mechanism includes a cover body, which is rotatably installed on one side of the boiler base. A filter grid is fixedly installed on the lower part of the cover body, and a cover plate is rotatably installed on one side of the cover body. A transmission pipe is fixedly installed through the support base, and a telescopic conduit is fixedly installed between the transmission pipe and the cover body.

[0010] Preferably, the outer diameter of the lid is the same as the inner diameter of the pot, and the outer diameter of the cover plate is the same as the inner diameter of the lid.

[0011] Preferably, a valve is fixedly installed on the transmission pipe, and the telescopic conduit is composed of a heat-resistant corrugated pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This device for improving boiler thermal efficiency controls the formation of a sealed space between the boiler base, the boiler body, and the support. When the heating wire is controlled to heat, the electric telescopic rod can be further controlled to change the distance between the heating wire and the boiler body. When the heating wire is far away from the boiler body, the boiler body mainly obtains heat from the hot air, resulting in a relatively mild boiler body temperature. When the heating wire is close to the boiler body, the boiler body temperature is higher, which can quickly heat the raw materials.

[0014] 2) In this device for improving boiler thermal efficiency, during the heating process of the thermal resistance wire, some hot air will be transferred to the transmission pipe and enter the cover body through the telescopic pipe. When in use, the transmission pipe is opened by controlling the valve, and the hot air further enters the telescopic pipe and enters the cover body through the telescopic pipe, so as to realize the hot air circulation in the boiler body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figures 1-4 A device for improving boiler thermal efficiency includes a boiler base 1, a boiler body 2 fixedly mounted on the upper part of the boiler base 1, and a heat-fixing mechanism 3 provided on the lower side of the boiler body 2. The heat-fixing mechanism 3 includes a support 301, which is fixedly mounted inside the boiler base 1. An electric telescopic rod 302 is fixedly mounted on the lower part of the support 301. A support 303 is fixedly mounted on the output end of the electric telescopic rod 302 and slidably mounted on the support 301. A slide 304 is fixedly mounted on the outside of the support 303, and a thermal resistance wire 305 is fixedly mounted inside the support 303.

[0023] See Figure 2 Furthermore, the support 303 has an arc-shaped groove inside, which is compatible with the arc-shaped groove of the pot body 2. The slide 304 has several sliding grooves on its outside, and the slide 304 is in close contact with the inner wall of the boiler base 1.

[0024] Specifically, the slide 304 is confined inside the boiler base 1 by the support 301, and the slide 304 is pressed tightly against the inner wall of the boiler base 1, so that a sealed space is formed between the boiler base 1, the pot body 2 and the support 303. When the heating resistance wire 305 is controlled to heat, the electric telescopic rod 302 can be further controlled to change the distance between the heating resistance wire 305 and the pot body 2. When the heating resistance wire 305 is far away from the pot body 2, the pot body 2 mainly obtains heat in the hot air, so that the temperature of the pot body 2 is relatively mild. When the heating resistance wire 305 is close to the pot body 2, the temperature of the pot body 2 is higher, and the raw materials can be heated quickly.

[0025] Example 2

[0026] Combination Figure 1 and Figure 3A circulation mechanism 4 is provided between the boiler body 2 and the support 303. The circulation mechanism 4 includes a cover 401, which is rotatably installed on one side of the boiler base 1. A filter screen 402 is fixedly installed on the lower part of the cover 401, and a cover plate 403 is rotatably installed on one side of the cover 401. A transmission pipe 404 is fixedly installed through the support 303, and a telescopic conduit 405 is fixedly installed between the transmission pipe 404 and the cover 401.

[0027] See Figure 3 Furthermore, based on Embodiment 1, the outer diameter of the cover 401 is consistent with the inner diameter of the pot body 2, the outer diameter of the cover plate 403 is consistent with the inner diameter of the cover 401, a valve is fixedly installed on the transmission pipe 404, and the telescopic conduit 405 is composed of heat-resistant corrugated pipe.

[0028] Specifically, during the heating process of the thermal resistance wire 305, some hot air will be transferred to the transmission pipe 404. When in use, the transmission pipe 404 is opened by controlling the valve, and the hot air further enters the telescopic conduit 405 and then enters the cover 401 through the telescopic conduit 405, so as to realize the hot air circulation in the pot body 2. The filter grid 402 plays a role in heat dissipation, and the cover plate 403 can prevent cold air from entering the pot body 2.

[0029] In actual operation, the slide 304 is confined inside the boiler base 1 by the support 301 and the slide 304 is pressed tightly against the inner wall of the boiler base 1, so that a sealed space is formed between the boiler base 1, the pot body 2 and the support 303. When the heating resistance wire 305 is controlled to heat, the electric telescopic rod 302 can be further controlled to change the distance between the heating resistance wire 305 and the pot body 2. When the heating resistance wire 305 is far away from the pot body 2, the pot body 2 mainly obtains heat in the hot air, so that the temperature of the pot body 2 is relatively mild. When the heating resistance wire 305 is close to the pot body 2, the temperature of the pot body 2 is higher, and the raw materials can be heated quickly.

[0030] During the heating process of the thermal resistance wire 305, some hot air will be transferred to the transmission pipe 404. When in use, the transmission pipe 404 is opened by controlling the valve, and the hot air further enters the telescopic conduit 405 and then enters the cover 401 through the telescopic conduit 405, realizing the circulation of hot air in the pot body 2. The filter grid 402 plays a role in heat dissipation, and the cover plate 403 can prevent cold air from entering the pot body 2.
