Description

Technical Field

[0001] This utility model relates to the field of high-nickel ternary material sintering furnaces, specifically to a condensate recovery device for the furnace door of a high-nickel ternary material sintering furnace. Background Technology

[0002] In the sintering process of high-nickel ternary materials, the generation of condensate at the furnace door is a major challenge. During the sintering process, a significant temperature difference exists between the high-temperature environment inside the furnace and the relatively low temperature at the furnace door, causing the high-temperature water vapor inside the furnace to condense rapidly into water droplets on the surface of the furnace door upon cooling.

[0003] If this condensate is not drained in a timely and effective manner, it will lead to many adverse consequences. On the one hand, the long-term accumulation of condensate near the furnace door will keep the metal parts of the furnace door in a humid environment, accelerating the oxidation and corrosion process of the metal, causing damage to the furnace door sealing structure, a significant decrease in sealing performance, and in turn causing problems such as heat loss and uneven temperature inside the furnace, seriously affecting the service life of the furnace door and the overall operational stability of the firing furnace.

[0004] On the other hand, if condensate drips directly onto the sagger that holds the material, the sudden temperature change and the impact of the water may cause cracks due to the characteristics of the sagger material, reducing the reusability of the sagger. If it drips onto the material, it will cause material contamination, change the chemical composition and physical properties of the material, and also cause uneven heating of the material during the firing process, affecting the crystal structure and performance consistency of the product, and reducing the stability of product quality. Utility Model Content

[0005] The purpose of this invention is to provide a condensate recovery device for the furnace door of a high-nickel ternary material sintering furnace, which can effectively collect and treat the condensate generated at the furnace door, prevent the condensate from having an adverse effect on the furnace door and the sintering material, thereby improving the operational stability of the sintering furnace and the product quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model proposes a condensate recovery device for the furnace door of a high-nickel ternary material sintering furnace, which includes a water storage tank, a water receiving tank, a filter tank, and a water storage tank.

[0008] The water storage tank is located at the bottom of the furnace door of the firing furnace, and both ends of the water storage tank are provided with drain outlets;

[0009] The water receiving trough is used to collect condensate discharged from the water storage tank. The water receiving trough corresponds to the drain outlet, and one end of the water receiving trough is also connected to the filter tank.

[0010] The water storage tank is connected to the filter tank and is used to introduce water from the filter tank into the water storage tank. The water storage tank is also equipped with a second drain valve.

[0011] As a further improvement, the bottom of the firing furnace is provided with a furnace body, the furnace door includes an outer door and an inner door, the water storage tank is provided at the bottom of the outer door and the water storage tank is sunken.

[0012] As a further improvement, the water receiving troughs are symmetrically arranged at both ends of the water storage tank.

[0013] As a further improvement, the water receiving tank is connected to a drain pipe and a conduit, with the other end of the conduit connected to a filter tank.

[0014] As a further improvement, the catheter is inclined at an angle between 10 and 30°.

[0015] As a further improvement, the filter canister and the conduit are detachably connected;

[0016] The filter tank contains at least one filter element.

[0017] As a further improvement, the water storage tank is located at the bottom of the filter tank, and the surface of the water storage tank is provided with a viewing window for observing the water level of the medium.

[0018] As a further improvement, the water storage tank and the filter tank are connected by a connecting pipe.

[0020] As a further improvement, the second drain valve can be a manual valve or an automatic valve.

[0021] Compared with the prior art, this utility model achieves the following technical effects:

[0022] The water storage tank of this device is reasonably designed with both ends sunken, which allows condensate to quickly collect and flow into the tank and be quickly discharged from the drain outlet. This effectively prevents condensate from accumulating at the furnace door, thus avoiding problems such as low product quality and short furnace door life caused by water accumulation at the furnace door.

[0023] The filter tank of this device can efficiently filter impurities in the condensate, preventing them from entering the storage tank and ensuring the cleanliness of the condensate. This significantly reduces the deposition of impurities in the storage tank and extends its service life. Furthermore, the filter tank features a detachable design, allowing for easy cleaning of the filter screen at any time. This simple and convenient maintenance ensures long-term stable operation of the device.

[0024] The first and second drain valves of this device can automatically drain water periodically, which not only reduces the tediousness and errors of manual operation, but also improves work efficiency. In addition, the device can monitor the condensate level in real time through the viewing window and perform drainage operations in a timely manner according to the actual situation.

[0025] This device effectively collects and treats condensate, which not only reduces the corrosion of the furnace door by condensate and extends the service life of the furnace door, but also prevents condensate from dripping onto the materials inside the furnace, avoiding material contamination and uneven firing, thereby improving the stability of product quality.

[0033] The embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. Rather, the embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0034] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0035] See Figure 1This utility model discloses a condensate recovery device for the furnace door of a high-nickel ternary material sintering furnace 1, comprising a water storage tank 5, a water receiving tank 7, a filter tank 10, and a water storage tank 11. The water storage tank 5 is located at the bottom of the furnace door of the sintering furnace 1, and both ends of the water storage tank 5 are provided with drain outlets 6. The water receiving tank 7 is used to receive the condensate discharged from the water storage tank 5, and the water receiving tank 7 corresponds to the drain outlets 6, wherein one end of the water receiving tank 7 is also connected to the filter tank 10. The water storage tank 11 is connected to the filter tank 10 and is used to introduce water from the filter tank 10 into the water storage tank 11, wherein the water storage tank 11 is also provided with a second drain valve 14.

[0036] like Figure 2 and Figure 3 The diagram shown is a schematic diagram of the firing furnace 1 in this embodiment. The bottom of the firing furnace 1 is provided with a furnace body 2, and the furnace door is provided at the feed inlet of the firing furnace 1. The furnace door consists of an outer door 3 and an inner door 4.

[0037] See Figure 4 In this embodiment, the water storage tank 5 is specifically installed at the bottom of the outer door 3 and the bottom of the inner door 4. Both ends of the water storage tank 5 are provided with drain outlets 6, and the two water storage tanks 5 are symmetrically arranged to ensure that the cooling water is discharged quickly in both directions.

[0038] In this embodiment, the two ends of the water storage tank 5 are 1cm lower than the center, forming a natural slope. This utilizes gravity to accelerate the water flow to the drain outlet 6. The sunken structure in this embodiment fundamentally solves the problem of water retention, preventing water from staying in the water storage tank 5 for a long time, which could lead to problems such as rust and perforation on the surface of the water storage tank 5, thus ensuring the long-term stable operation of the water storage tank 5. In this embodiment, the drain outlet 6 is vertically aligned with the water receiving tank 7 below, ensuring that the water can flow directly into the water receiving tank 7 in the shortest path, thereby improving drainage efficiency and allowing the water to be quickly discharged from the water storage tank 5, further reducing the time the water stays in the water storage tank 5.

[0039] See Figure 5 In this embodiment, the water receiving trough 7 is installed on the steel frame at the bottom of the furnace body 2 and is vertically aligned with the drain outlet 6, ensuring that the water receiving trough 7 can be aligned with the drain outlet 6. This allows the water flowing out of the drain outlet 6 to fall directly into the water receiving trough 7, avoiding water splashing or leakage caused by alignment deviation, and effectively improving the stability and reliability of drainage. In this embodiment, the water receiving trough 7 is also symmetrically arranged, matching the two drain outlets 6 of the water trough, ensuring that the water flow is evenly distributed in the water receiving trough 7, and preventing the situation where there is too much water on one side and too little water on the other side, which helps to improve drainage efficiency.

[0040] In this embodiment, the other end of the water receiving tank 7 is connected to the drain pipe 8, and the connection between the water receiving tank 7 and the drain pipe 8 is firm and reliable, ensuring that there will be no loosening or leakage during use. The drain pipe 8 is connected to the conduit 9, and the conduit 9 is connected to the filter tank 10. In this embodiment, the conduit 9 can guide the accumulated water into the filter tank 10. The conduit 9 in this embodiment is inclined, with an inclination angle of 10 to 30°. In this embodiment, it is preferably 15°, which can ensure that the accumulated water can flow from the water receiving tank 7 to the filter tank 10 by gravity alone without the need for additional pumping power. When the accumulated water enters the conduit 9, it will slide down the inner wall of the conduit 9 under the action of gravity, gradually gather and accelerate the flow, and finally flow into the filter tank 10, thereby reducing the operating cost of the equipment.

[0041] In this embodiment, the filter tank 10 and the conduit 9 are detachably connected. The detachable connection can be achieved through a threaded interface or a quick connector. During actual operation, the filter tank 10 filters various impurities in the accumulated water. Over time, a large amount of impurities will gradually accumulate inside the filter tank 10. The detachable design allows maintenance personnel to easily remove the filter tank 10 from the conduit 9 to clean or replace the filter elements inside the filter tank 10, which greatly improves maintenance efficiency and reduces maintenance costs.

[0042] The filter tank 10 in this embodiment is equipped with at least one layer of filter elements, which can be a filter screen, a filter cartridge, or a combination of a filter screen and a filter cartridge. The filter screen and filter cartridge can filter out impurities such as metal oxides and dust in the condensate. Since the filter tank 10 is detachable, it can be removed periodically by maintenance personnel during operation to thoroughly clean the impurities accumulated inside. By removing impurities in a timely manner, the passage can be kept unobstructed, ensuring that condensate can pass through the filter tank 10 and preventing the filter tank 10 from becoming clogged.

[0043] See Figure 6 In this embodiment, the filter tank 10 is connected to the water storage tank 11 via a connecting pipe. The water storage tank 11 is used to store the filtered water. In this embodiment, the water storage tank 11 is located directly below the filter tank 10. The viewing window 12 provided on the water storage tank 11 can monitor the water level. When the water level is almost full, it can remind people to empty the water in the water storage tank 11.

[0044] In this embodiment, the water storage tank 11 is provided with a first drain valve 13 and a second drain valve 14. The first drain valve 13 is located on the connecting pipe and is preferably a solenoid valve. By cooperating with a timer, the solenoid valve can periodically introduce water from the filter tank 10 into the water storage tank 11. The second drain valve 14 is specifically located at the bottom of the water storage tank 11. The second drain valve 14 can be installed as a manual valve or an automatic valve as needed to assist in drainage. For example, when a manual valve is used, drainage can be performed manually.

[0045] The workflow of this embodiment is as follows: high-temperature steam at the furnace door condenses upon cooling to form condensate, which flows into the water storage tank 5 along the furnace door. The water in the water storage tank 5 quickly flows to the drain outlets 6 at both ends under the action of gravity.

[0046] Condensate falls vertically from drain outlet 6 into water receiving tank 7, then through drain pipe 8 into inclined conduit 9. Condensate is then guided through conduit 9 to filter tank 10 for filtration, where impurities or contaminants are adsorbed. The filtered water then flows through connecting pipe into storage tank 11 for storage, completing the entire process.

[0047] In addition, the water level in the storage tank 11 can be monitored through the viewing window 12.
