Abstract
Description
Technical Field
[0001] This utility model relates to the field of radar detection technology for alumina preparation, specifically a heat dissipation device for a radar level gauge. Background Technology
[0002] Alumina preparation is a crucial step in the aluminum industry, primarily extracted from bauxite using the Bayer process or sintering method. The process mainly includes leaching, settling, decomposition, and roasting, involving harsh conditions such as high temperature, high pressure, and strong alkali. In core equipment such as settling tanks, hot water tanks, and seed tanks, the material temperature typically reaches 90-150℃, accompanied by corrosive media and adhesive particles.
[0003] Currently, radar and ultrasonic level gauges are commonly used in alumina production sites. When measuring high-temperature materials in alumina plants such as settling tanks, hot water tanks, and seed tanks, the temperature at the instrument often exceeds the allowable value, leading to instrument malfunctions such as freezing, no display change, and inaccurate display, resulting in serious damage to production. Summary of the Invention
[0004] The purpose of this utility model is to provide a heat dissipation device for radar level gauges. In response to the situation where the measurement environment temperature is higher than the allowable temperature range of the radar level gauge (generally not exceeding 60°C), which leads to measurement failure, a heat dissipation device is installed on the radar level gauge to reduce the impact of the instrument's ambient temperature on the instrument's measurement and improve the instrument's service life.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a radar level gauge heat dissipation device, comprising a radar level gauge, a heat dissipation device, and a seeding tank, wherein the bottom of the radar level gauge is connected to the heat dissipation device via a flange, and the bottom end of the heat dissipation device is fixedly connected to the seeding tank via a flange.
[0006] Preferably, the heat dissipation device includes an upper flange, a heat dissipation cylinder, an air inlet, an air outlet, and a lower flange. The radar level gauge is fixedly connected to the upper flange via a flange plate. The bottom of the upper flange is fixedly connected to the heat dissipation cylinder, and the bottom of the heat dissipation cylinder is fixedly connected to the lower flange.
[0007] Preferably, the heat sink has a hollow structure, and an air inlet and an air outlet are respectively opened on the outer end face of the heat sink.
[0008] Preferably, the air inlet can be connected to an external fan, and the surface of the air outlet is provided with a filter screen.
[0009] Compared with the prior art, the beneficial effects of this utility model are: This invention indirectly connects the radar level gauge to the high-temperature seed tank through a heat dissipation cylinder, avoiding direct contact between the instrument and high-temperature equipment, significantly reducing the ambient temperature of the instrument and protecting the core components from thermal damage.
[0010] This utility model features an air inlet and outlet in its heat sink design, supporting forced ventilation via an external fan. It utilizes pressurized cooling air (0.4-0.6MPa) to actively remove heat, achieving dual cooling (isolation + air cooling) to ensure stable operation of the instrument under high-temperature conditions.
[0011] This utility model directly replaces the original flange connection by using a combination of a hollow heat dissipation cylinder and a flange, making installation convenient and requiring no complicated modifications; the air outlet filter design prevents dust from entering, taking into account both heat dissipation and pollution prevention.
[0012] This invention reduces the ambient temperature of the instrument and promotes active heat dissipation, thereby preventing electronic components from aging or failing due to high temperatures, reducing the failure rate, and improving long-term operational stability. It is suitable for high-temperature industrial scenarios such as metallurgy and chemical industries.
[0013] This invention achieves efficient heat dissipation with a simple mechanical structure, reducing the cost of instrument repair or replacement due to high temperature, and is cost-effective. Attached Figure Description

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] 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.
[0020] Please see Figs. 1-3 The present invention provides an embodiment of a radar level gauge heat dissipation device, comprising a radar level gauge 1, a heat dissipation device 2, and a seeding trough 3. The bottom of the radar level gauge 1 is connected to the heat dissipation device 2 via a flange, and the bottom end of the heat dissipation device 2 is fixedly connected to the seeding trough 3 via a flange.
[0021] Furthermore, the heat dissipation device 2 includes an upper flange 201, a heat dissipation cylinder 202, an air inlet 203, an air outlet 204, and a lower flange 205. The radar level gauge 1 is fixedly connected to the upper flange 201 via a flange. The bottom of the upper flange 201 is fixedly connected to the heat dissipation cylinder 202, and the bottom of the heat dissipation cylinder 202 is fixedly connected to the lower flange 205. Changing the direct connection of the radar level gauge 1 to the seed tank 3 to an indirect connection of the radar level gauge 1 to the seed tank 3 via the heat dissipation cylinder 202 allows the equipment to be effectively kept away from the high-temperature environment and avoid direct contact with the high-temperature seed tank 3, thereby achieving the effect of cooling the equipment.
[0022] Furthermore, the heat sink 202 has a hollow structure, and an air inlet 203 and an air outlet 204 are respectively opened on the outer end face of the heat sink 202. By opening the air inlet 203 and the air outlet 204, the heat sink 202 can be cooled by an external fan device, which can actively cool the radar level gauge 1 and avoid high temperature operation affecting the operation of the equipment.
[0023] Furthermore, the air inlet 203 can be connected to an external fan, and the surface of the air outlet 204 is equipped with a filter screen.
[0024] Working principle: When installing the radar level gauge 1 on site, first connect the radar level gauge 1 to the upper flange 201 of the heat dissipation device 2 via a flange, and then install the lower flange 205 of the heat dissipation device 2 to the material inlet being measured via a flange. Simultaneously, cooling air is introduced into the heat dissipation device 2. The presence of the heat dissipation device 2 extends the distance between the instrument and the material inlet, thus reducing the ambient temperature at the instrument. Through the connection between the heat dissipation device 2 and the cooling air, the pressurized (0.4-0.6MPa) cooling air carries away some heat, further reducing the ambient temperature at the instrument and ensuring that the instrument components operate normally within a controllable range.
