Description

Technical Field

[0001] The utility model relates to the technical field of furnace cooling, in particular to a furnace cooling device. Background Art

[0002] The development history of furnace cooling devices can be traced back to the early stages of industrial production. With the advancement of furnace technology and the increase in industrial production needs, cooling devices have gradually evolved from simple external cooling to built-in efficient cooling systems. In the early days, furnace cooling mainly relied on external cooling equipment, such as cooling fans or water cooling systems. Although these systems can reduce the temperature of the furnace to a certain extent, they are inefficient and it is difficult to achieve precise temperature control inside the furnace.

[0003] However, ordinary water-cooling equipment usually faces the problem of low water cooling efficiency. Impurities and particulate matter contained in the cooling water are easy to form deposits inside the pipes and heat exchangers, resulting in water blockage, affecting the flow of cooling medium and heat exchange effect. Secondly, improper maintenance of water-cooling equipment will also lead to reduced efficiency. If the equipment is operated for a long time without necessary cleaning and maintenance, the accumulated dirt and corrosion products will further reduce the cooling efficiency. In addition, unstable temperature control during furnace operation may also affect the efficiency of water-cooling equipment. Excessive temperature fluctuations will make it difficult for water-cooling equipment to adapt, thus affecting its cooling effect and operational stability. Utility Model Content

[0009] Preferably, the cooling water tank is provided with a pressure relief valve and a drain port, and the pressure relief valve is threadedly connected to the cooling water tank.

[0010] (III) Beneficial effects: Compared with the prior art, the utility model provides a furnace cooling device with the following beneficial effects:

[0011] 1. The furnace cooling equipment can achieve rapid and stable cooling in the furnace through the cooperation of water cooling and air cooling. In the furnace, the large-area heat sink of the circulating heat absorption part can provide good thermal conductivity. The high temperature inside the furnace can be quickly transferred to the cooling pipe and the cooling medium therein through the heat sink. The cooling medium flows from the circulating heat absorption part to the heat dissipation part under the pressure of the water pump. The heat sink of the heat dissipation part is made of copper material inside and aluminum material outside. The core of the copper material has good thermal conductivity and can quickly conduct the heat of the cooling medium to the heat sink. The external aluminum material has good heat dissipation and can quickly release the heat to the surrounding air. The airflow blown by the cooling fan accelerates the flow of surrounding air, thereby taking away more heat.

[0012] 2. The furnace cooling equipment, the heat sink and the heat sink plate both adopt a design that is approximately diamond-shaped. The cross-section of the two is thin on both sides and thick in the middle. The part close to the cooling pipe is thickened to increase the heat conduction area with the cooling pipe, so that the heat in the cooling medium can be quickly conducted out. When the air flows through the surface of the heat sink, it will be subject to resistance of different thicknesses, forming a certain pressure difference. This pressure difference can cause the air to flow through the surface of the heat sink faster, thereby improving the heat dissipation effect.

[0013] 3. The furnace cooling equipment has a high-frequency electromagnetic field generator installed at the water inlet of the cooling pipe. Matching electrodes are installed inside the pipe section, and the controller is integrated inside the control cabinet. The high-frequency electromagnetic field generator will generate a high-frequency electromagnetic field. This electromagnetic field acts on the cooling medium flowing through the pipe, causing it to absorb electromagnetic energy and change its physical structure. This change includes breaking the binding bonds of the original large complex and converting it into water in a more active single molecule or small complex state, which promotes the orderly arrangement of water molecules and enhances the decomposition effect of water on scaling ions and their components. When the high-frequency magnetic field acts, the electrodes will generate electric pulses, further enhancing the anti-scaling and descaling effects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 A furnace cooling device includes a circulating heat absorption part, a heat dissipation part, a descaling part and a control cabinet 4. The circulating heat absorption part is installed inside the furnace, including a cooling pipe 1 and a heat sink 2. The cooling pipe 1 is arranged in a transverse bending manner. Eight heat sinks 2 are longitudinally fixedly installed between the cooling pipes 1. The fixed connection between the two forms a frame structure, which strengthens the structural strength of the entire circulating heat absorption part and avoids deformation and leakage caused by temperature changes during cooling. The heat sink 2 and the cooling pipe 1 are both made of copper material with good thermal conductivity and ductility. The heat sink 2 has a large area, is thin on both sides and thick in the middle. Such a structure increases the contact area between the heat sink 2 and the cooling pipe 1, which not only strengthens the structural strength, but also improves The heat conduction efficiency allows the heat inside the furnace to be quickly transferred to the cooling medium with a lower temperature inside the cooling pipe 1, and then brought out of the furnace through the circulation of the cooling medium, so that the temperature inside the furnace is always maintained within a certain range; there are a pressure relief valve 12 and a drain port 13 on the cooling water tank 7, and the cooling water tank 7 is connected to the pressure relief valve 12 by threads. The pressure relief valve 12 can be removed to add cooling water to the cooling water tank 7 and the connected cooling pipe 1. After the internal air is basically emptied, the entire circulation system is in a sealed state during operation. When the temperature of the cooling water is too high to generate steam, the excess steam is brought into the cooling water tank 7 under circulation, and then discharged from the pressure relief valve 12, so as to avoid damage to the entire equipment caused by high-temperature and high-pressure steam.

[0020] See also Figure 1 and Figure 2 The heat dissipation part includes a heat sink 3, a heat dissipation fan 6 and a cooling water tank 7. The heat sink 3 is a copper-aluminum composite heat sink. Since the core of the heat sink is copper with good thermal conductivity, when the cooling medium with heat flows to the liquid outlet pipe where the heat sink is located, the heat in the cooling pipe can be quickly transferred to the heat sink. The outside that contacts the air is aluminum with good heat dissipation, which can quickly transfer the heat on the heat sink to the surrounding air. The cross-section of the evenly arranged heat sink 3 is approximately diamond-shaped, thin on both sides and thick in the middle. When the air flows through the surface of the heat sink, it will be subject to resistance of different thicknesses, thereby generating a pressure difference, which accelerates the flow of air. Combined with the airflow brought by the heat dissipation fan 6, the heat release of the heat sink 3 is further accelerated.

[0021] See also Figure 3 The high-frequency electromagnetic field generator 8 of the descaling part is wrapped around the outside of the liquid inlet pipe 10. When it is started, the component generates a high-frequency electromagnetic field through an electronic integrated circuit, so that the water molecules flowing through it can absorb electromagnetic energy, thereby changing their physical structure. The original large complex bond will be broken and transformed into a single molecule or small complex state of water with higher activity. This change not only promotes the orderly arrangement of water molecules and enhances the dipole moment of water, but also strengthens the decomposition of water on scale-forming ions and their components, and improves the water molecules' ability to water and scale-forming components such as calcium and magnesium ions and carbonate ions. The electrode is directly installed inside through the opening on the cooling pipe and is in direct contact with the cooling water. When the descaling function is started, the electrode 9 generates an electric pulse and directly acts on the cooling water body. The electric pulse with a specific frequency and waveform can not only change the hydrogen bonds between water molecules, thereby changing the physical properties of water, but also change the motion state of ions in water, affecting the living environment of microorganisms such as bacteria and algae in water, and further playing a role in sterilization and algae removal.

[0022] Working principle: The cooling pipe 1 and the heat sink 2 of the circulating heat absorption part are installed inside the furnace, and the other parts are outside the furnace. The circulating heat dissipation part and other parts are connected through the liquid inlet pipe 10 and the liquid outlet pipe 11. The control cabinet 4 controls the operation of the water pump 5, the cooling fan 6 and the descaling part. When the equipment is started, the water pump 5 drives the cooling water to flow in the pipe, and pumps the water in the cooling water tank 7 into the circulating heat absorption part in the furnace through the liquid inlet pipe 10. When the cooling water passes through the descaling part, the high-frequency electromagnetic field generated by the high-frequency electromagnetic field generator 8 acts on the water body, and the electric pulse generated by the electrode 9 directly in contact with the water body changes the physical properties of the water, effectively controlling the generation of scale in the water body. After the cooling water enters the circulating heat absorption part, the large The heat sink 2 with a large area quickly transfers the high temperature in the kiln to the cooling pipe 1 and the cooling water therein. The cooling water is heated up and leaves the kiln from the liquid outlet pipe 11 at the upper part of the circulating heat absorption part under the promotion of its own density and the water pump 5, and enters the heat dissipation part. There are heat sinks 3 arranged evenly at intervals on the liquid outlet pipe 11. The heat carried by the cooling water is transferred to the heat sink 3 through the pipe, and then the heat is transferred to the surrounding air through the heat sink 3. The airflow generated by the cooling fan 6 passes through the surface of the heat sink 3, which accelerates the flow of air and heat conduction, and speeds up the cooling speed. Subsequently, the cooling water that has been cooled returns to the cooling water tank 7. The control cabinet 4 can control the water pump 5 and the cooling fan 6 in conjunction with the thermometer to achieve temperature regulation inside the kiln.

[0023] To sum up, in the furnace cooling equipment, the large-area heat sink 2 of the circulating heat absorption part inside the furnace can provide good thermal conductivity, and the high temperature inside the furnace can be quickly transferred to the cooling pipe 1 and the cooling medium therein through the heat sink 2. The cooling medium flows from the circulating heat absorption part to the heat dissipation part under the pressure of the water pump 5. The heat sink 3 of the heat dissipation part is made of copper material inside and aluminum material outside. The core made of copper material has good thermal conductivity and can quickly conduct the heat of the cooling medium to the heat sink 3. The external aluminum material has good heat dissipation and can quickly release the heat to the surrounding air. The airflow blown by the cooling fan 6 accelerates the flow of surrounding air, thereby taking away more heat. Both the heat sink 3 and the heat sink plate 2 adopt a design that is approximately diamond-shaped. The cross-sections of the two are thin on both sides and thick in the middle. The portion close to the cooling pipe 1 is thickened to increase the heat conduction area with the cooling pipe 1, so that the heat in the cooling medium can be quickly conducted out. When the air flows through the surface of the heat sink 3, it will be subject to resistance of different thicknesses, forming a certain pressure difference. This pressure difference can cause the air to flow through the surface of the heat sink 3 faster, thereby improving the heat dissipation effect. The furnace cooling equipment has a high-frequency electromagnetic field generator 8 installed at the liquid inlet pipe 10 of the cooling pipe 1, and a matching electrode 9 is installed inside the pipe section. The controller is integrated in the control cabinet 4, wherein the high-frequency electromagnetic field generator 8 generates a high-frequency electromagnetic field, which acts on the cooling medium flowing through the pipe, causing the cooling medium to absorb electromagnetic energy and change its physical structure. This change includes breaking the binding bonds of the original large complex and converting it into water in a single molecule or small complex state with higher activity, which promotes the orderly arrangement of water molecules and enhances the decomposition effect of water on scaling ions and their components. When the high-frequency magnetic field acts, the electrode 9 generates electric pulses, which further enhances the effect of anti-scaling and descaling, reduces the damage of scale to the equipment, extends its service life, and improves the equipment use efficiency. In general, this equipment combines the advantages of air cooling and water cooling. Water cooling is used for internal heat conduction. Water has a large specific heat capacity and can better control the temperature inside the furnace. The heat can be quickly brought out of the furnace through circulation, avoiding damage to internal equipment and increasing the service life of the equipment. Air cooling can transfer most of the heat to the air, achieving rapid cooling of the cooling medium, and then participating in the next cycle. The combination of the two can not only make temperature control more precise and flexible, but also achieve more efficient energy utilization and reduce energy consumption.
