Description

Technical Field

[0001] This utility model relates to the field of precious metal production technology, specifically to a reactor lid. Background Technology

[0002] Enameled reactors are reaction vessels made by lining the inner surface of a steel container with high-silica glass, then firmly bonding it to the metal surface through high-temperature firing. They possess the dual advantages of glass stability and metal strength, and are widely used in the precious metals industry. The reactor lid, as a crucial component of the enamel-lined reactor, directly affects the reactor's performance. However, traditional enamel-lined reactor lids have significant drawbacks in the precious metals industry, specifically as follows: The vessel lid is quite heavy. Traditional vessel lids are mostly made of carbon steel, resulting in a large overall weight and making installation, transportation, and handling difficult. Maintenance is inconvenient; due to the weight of the lid, moving and flipping it during maintenance is difficult, increasing the difficulty and time cost. The connecting metal screws are easily corroded. The metal screws directly connecting the vessel body and lid are exposed to the reaction environment for a long time and are easily corroded by the material. This not only affects the strength of the connection but may also lead to leaks and other safety hazards due to screw damage. The feed port design is inappropriate. The feed port is usually tilted at a certain angle. When adding precious metal materials, the material is prone to falling to the ground due to the angle, resulting in waste of precious metal materials, economic losses, and pollution of the operating environment, increasing the cleaning burden. The enamel layer is prone to peeling off. Due to insufficient bonding between the substrate and the enamel layer, the enamel layer is prone to peeling off and falling into the vessel under long-term use or when affected by mechanical impact, temperature changes, etc., contaminating the material, affecting the purity of the material, and even damaging the equipment. Utility Model Content

[0003] This utility model provides a reactor lid to solve the problems of easy enamel layer falling off, poor corrosion resistance, heavy weight, inconvenient maintenance, and material falling off due to the tilt of the feeding port in current reactor lids.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A reactor lid includes a lid body, a first rim on the top outer edge of the lid body, a second rim on the bottom of the first rim, and the second rim fitting snugly against the lid body. A maintenance port cover is horizontally rotatable on the lid body. The lid body also has a condenser connection port, a reagent port, and a waste gas port. A feeding port is provided on the maintenance port cover, and a third rim is provided on the outer edge of the feeding port. Multiple reinforcing ribs are provided in the center of the lid body, and a motor mounting port is fixed on the reinforcing ribs. An agitator inlet and outlet are provided in the center of the lid body corresponding to the motor mounting port. An annular plate is fixed on the bottom outer edge of the lid body.

[0005] Furthermore, an observation port is provided on the main body of the vessel lid.

[0006] Furthermore, a feeding cover is provided on the feeding port, and a handle is provided on the feeding cover.

[0007] Furthermore, the main body of the vessel lid and the reinforcing ribs are made of PP material.

[0008] Furthermore, the feeding port adopts a planar structure and has no angle of inclination.

[0009] Furthermore, the stirring motor is detachably connected to the motor mounting port via titanium screws.

[0010] This utility model has the following beneficial effects: The main body of the vessel lid is made of PP material and reinforced with PP ribs, which not only ensures the structural strength of the lid but also significantly reduces the overall weight. There is no risk of enamel layer peeling off, reducing the difficulty of transportation and installation. At the same time, PP material has excellent resistance to acid and alkali corrosion, fundamentally avoiding the corrosion problems that are prone to occur with metal materials, further improving the durability and applicability of the product, and providing reliable protection for use in different scenarios.

[0011] The inspection port cover is connected by hinges, allowing for a large opening angle and facilitating internal equipment inspection. The transparent observation window of the observation port allows real-time monitoring of the reaction inside the vessel without opening the lid. During the reaction, waste gas generated during the reaction can be promptly extracted and treated through the exhaust port to ensure production safety, maintain environmental cleanliness, and optimize reaction conditions. Adding reagents through the reagent port does not require opening the lid, enabling convenient operation in a closed state, reducing material loss and pollution, and improving safety and efficiency. The lid body is connected to the vessel body via titanium screws on a ring plate, allowing for disassembly and operation of internal maintenance, cleaning, and material loading, balancing the sealing of the reaction process with the convenience of equipment maintenance.

[0012] The first edge effectively solves the problem of material falling from the feeding port onto the ground during feeding, thus preventing waste. The second edge on the lid effectively prevents acidic or alkaline liquids remaining on the lid from entering the vessel through the bolt holes during rinsing with water, thus corroding the titanium screws. The third edge on the lid can prevent the spread of volatile, corrosive, toxic, and other hazardous materials, reducing the safety risks to personnel and equipment. It can also concentrate residual materials in a fixed area, simplifying cleaning and maintenance and reducing damage to equipment components from corrosive materials.

[0013] The feeding port adopts a flat structure without any angle of inclination, which allows materials to enter the reactor more smoothly during the feeding process, effectively reducing material waste. This simplifies the operation process and improves production efficiency. The inspection port cover has a large opening angle, which facilitates the feeding of large quantities of materials. The feeding port is convenient for adding small doses of materials, and the feeding port cover can ensure the sealing during feeding. The reactor lid body and the reactor body are connected by an annular plate, which provides a rigid connection base and forms a tight-fitting sealing interface. With the evenly distributed titanium screws for fastening, excellent sealing performance can be achieved, effectively preventing the leakage of reactants. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-2 As shown, a reactor lid includes a lid body 1. The lid body 1 has a first rim 2 on its top outer edge and a second rim 3 on its bottom. The second rim 3 is fitted to the lid body 1. A maintenance port cover 10 is horizontally rotatable on the lid body 1. The lid body 1 also has a condenser connection port 18, a reagent port 19, and a waste gas port 20. The maintenance port cover 10 has a feeding port 11. The feeding port 11 has a third rim 4 on its outer edge. The lid body 1 has multiple reinforcing ribs 5 in the center. A motor mounting port 8 is fixed on the reinforcing ribs 5. A stirring paddle inlet / outlet 17 is opened at the center of the lid body 1 corresponding to the motor mounting port 8. An annular plate 16 is fixed on the bottom outer edge of the lid body 1.

[0019] An observation port 21 is provided on the main body 1 of the vessel lid.

[0020] The feeding port 11 is provided with a feeding cover plate 12, and the feeding cover plate 12 is provided with a handle 13.

[0021] In practical use, the operator aligns the annular plate 16 with the edge of the reactor body, then passes the titanium screw through the second bolt hole 15 and fixes it. The stirring paddle is placed into the stirring paddle inlet / outlet 17, and the end of the stirring paddle is fitted into the hole of the power installation port 8. The motor and stirring paddle are then connected together. A titanium screw is passed through the first bolt hole 7 on the power installation port 8 and fixed to the connecting plate 6, thus simultaneously fixing the stirring paddle and motor. The motor is turned on, causing the stirring rod to work inside the reactor. The condenser connection port 18 is connected to a conduit, simultaneously introducing condensate into the reactor. When a large amount of material needs to be added, an inspection port 9 is provided on the reactor lid body 1. Opening the inspection port... The cover plate 10 is used for feeding materials. The inspection port cover plate 10 is connected to the reactor lid body 1 via a hinge 14. It has a large opening and closing angle. When a small amount of material needs to be fed, the inspection port cover plate 10 has a feeding port 11. The operator can open the feeding port cover plate 12 on the feeding port 11 through the handle 13. When it is necessary to add reagents, the reagent port 19 can be opened to add the reagents. The observation port 21 is a transparent window. During the reaction, the reaction can be observed through the observation port 21. At the same time, the waste gas generated in the reaction can be extracted through the exhaust port 20. When maintenance is required, it can be carried out through the inspection port cover plate 10. Alternatively, the reactor lid body 1 can be disassembled for maintenance by loosening the titanium screws on the annular plate 16.

[0022] The reinforcing rib 5 on the top of the reactor lid body 1 can enhance the rigidity of the reactor lid, making it more durable and less prone to deformation. The outer edge of the reactor lid body 1 is provided with a first surrounding edge 2, so that the material splashed during feeding will not fall to the outside of the reactor lid body 1, and the material can be washed into the reactor body by water flow. The second surrounding edge 3 on the top side of the reactor lid body 1 is higher than the titanium screw, which can effectively solve the problem that acid and alkali liquids remaining on the reactor lid can enter the reactor through the bolt hole during water rinsing, thereby corroding the titanium screw. The outer edge of the feeding port 11 is provided with a third surrounding edge 4 to ensure that the material will not splash when feeding.
