Description

Technical Field

[0001] This utility model relates to the field of ferric phosphate preparation equipment, specifically a drying device for ferric phosphate preparation. Background Technology

[0002] The drying equipment for ferric phosphate preparation is a type of equipment that uses a high-efficiency centrifugal spray dryer as its core. It disperses the ferric phosphate slurry into tiny droplets through a high-speed rotating centrifugal disc, which then quickly and fully contact and exchange heat with hot air to achieve a rapid and uniform drying effect. This equipment not only greatly improves drying efficiency and reduces drying time, but also effectively avoids changes in material properties caused by local overheating, ensuring the quality and stability of ferric phosphate products. In addition, this drying equipment is usually equipped with an advanced temperature control and dust recovery system, which can reduce energy consumption and environmental pollution while ensuring production efficiency, thus achieving green production.

[0003] During long-term use, centrifugal spray dryers used for ferric phosphate preparation may experience extremely minor gas leaks due to factors such as aging, wear, or damage to seals, increased clearance between the main shaft and bearings, and loosening or cracking of connections caused by long-term equipment vibration. Although these leaks are small, if they are not detected and addressed in time, they may affect the normal operation of the equipment, reduce production efficiency, and even cause some environmental pollution. However, these extremely minute leaks cannot be effectively observed with the naked eye, making it difficult for staff to detect and repair them in a timely manner. Utility Model Content

[0033] A drying device for the preparation of ferric phosphate, such as Figures 1-4As shown, the device includes a hot air unit 1, a centrifugal spray drying unit 2, a separation unit 3, and a waste gas treatment unit 4. The hot air unit 1, centrifugal spray drying unit 2, separation unit 3, and waste gas treatment unit 4 are connected by an air duct 6.

A sliding seat 705 is provided in the sliding groove 704, and pulleys 706 are provided at the top and bottom of the sliding seat 705. The sliding seat 705 moves along the sliding groove 704 via the pulleys 706. 4. A sliding connection is provided. An installation plate 707 is provided on the inner side of the sliding seat 705, and a top plate 708 and a bottom plate 709 are provided on the top and bottom of the installation plate 707, respectively. A drive wheel 710 is provided on the inner side of the top plate 708 and the bottom plate 709, and the drive wheel 710 is rotatably connected to the installation plate 707. A motor 711 is provided on the upper side of one side of the installation plate 707, and the output end of the motor 711 is connected to the drive wheel 710. An infrared thermal imaging gas leak detection device 8 is detachably connected to the middle of one side of the installation plate 707 through a connecting frame 712. This design ensures close cooperation and efficient operation of each link in the drying process. At the same time, the addition of the exhaust gas treatment device 4 is beneficial to environmental protection and reduces the emission of harmful gases.

[0034] See Figure 3 , Figure 4 The infrared thermal imaging gas leak detection device 8 includes a body 801, with two visual detection heads 802 on one side of the body 801. This design enhances the safety monitoring capability of the device, enabling it to detect gas leaks in the gas pipeline 6 in real time and accurately, and to promptly identify and address potential safety hazards.

[0035] See Figure 1 , Figure 2 The bottom of the first connecting frame 701 and the second connecting frame 702 is provided with reinforcing ribs 713. The reinforcing ribs 713 are used to improve the strength of the first connecting frame 701 and the second connecting frame 702. The reinforcing ribs 713 at the bottom of the first connecting frame 701 and the second connecting frame 702 can significantly improve the structural strength of the mounting mechanism 7 and ensure the stability and reliability of the infrared thermal imaging gas leak detection device 8 during the sliding process.

[0036] See Figure 1 , Figure 4The sliding seat 705 and the mounting plate 707 are used to cause the infrared thermal imaging gas leak detection device 8 to slide periodically. The infrared thermal imaging gas leak detection device 8 is used to detect the real-time leakage of the gas pipeline 6.

The other end of the liquid delivery pipe 10 is connected to the raw material tank. The atomizer 9 and the liquid delivery pipe 10 at the top of the centrifugal spray dryer 2 achieve uniform atomization and efficient conveying of the raw material, which helps to improve drying efficiency and product quality. At the same time, the direct connection between the liquid delivery pipe 10 and the raw material tank simplifies the process flow and reduces material loss.

[0038] See Figure 1 , Figure 2 A ladder 5 is provided on one side of the centrifugal spray drying device 2. The ladder 5 facilitates the inspection of the internal condition of the centrifugal spray drying device 2. The ladder 5 on one side of the centrifugal spray drying device 2 provides a convenient passage for operators to enter the equipment for inspection and maintenance, thereby improving the maintainability and safety of the equipment.

[0039] See Figure 1 , Figure 4 The mounting mechanism 7 is made of aluminum alloy, and the body 801 is made of engineering plastic.

Aluminum alloy also has good thermal conductivity, which helps the equipment dissipate heat and operate stably. Engineering plastic has excellent insulation properties and mechanical strength, which can protect internal components from the influence of the external environment.

[0040] The implementation principle of this utility model is as follows: First, ensure that the hot air device 1, centrifugal spray drying device 2, separation device 3 and waste gas treatment device 4 are all in good working condition and are correctly connected through the air outlet pipe 6. Check whether the infrared thermal imaging gas leak detection device 8 is installed firmly and ensure that its body 801 and two visual detection heads 802 are clean and unobstructed. Confirm that the atomizer 9 on the top of the centrifugal spray drying device 2 is connected to the liquid outlet pipe 10 correctly. The other end of the liquid outlet pipe 10 is connected to the raw material tank to receive the iron phosphate slurry.

[0041] Subsequently, the hot air device 1 is started to preheat the drying system to the set temperature. The iron phosphate slurry is delivered to the atomizer 9 through the liquid pipe 10 to start the atomization process. The parameters of the centrifugal spray dryer 2 are adjusted to ensure the atomization effect and drying efficiency. The working status of the separation device 3 and the exhaust gas treatment device 4 are checked regularly to ensure that the exhaust gas is discharged in compliance with regulations.

[0042] The motor 711 is scheduled to start periodically, driving the drive wheel 710 to rotate, which in turn causes the sliding seat 705 and the mounting plate 707 to slide within the slide groove 704. As the mounting plate 707 moves, the infrared thermal imaging gas leak detection device 8 scans the gas pipeline 6 in real time to detect whether there is a gas leak. If a leak is found, the location is recorded immediately and the machine is stopped for inspection. The ladder 5 is used to enter the centrifugal spray drying device 2 or other relevant areas for detailed inspection and repair.

[0043] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
