A roasting furnace for palladium extraction and recovery

Abstract

This utility model discloses a roasting furnace for extracting and recovering palladium, comprising a base plate, two mounting plates fixedly connected to the outer surface of the base plate, an electric push rod fixedly mounted on the outer surface of each mounting plate, and a support block fixedly connected to the output end of each electric push rod. The outer surface of the two support blocks shares a common roasting furnace body, and the outer surface of the roasting furnace body has several limiting holes. This device utilizes a heating element to fully heat the interior of the roasting furnace body, extracting palladium from palladium-containing fertilizer. A counterweight increases the weight on one side of the roasting furnace body, allowing it to automatically sway under gravity, thus causing the palladium-containing waste to sway along with it, preventing localized overheating. Elastic elements, spring-loaded blocks, and dampers enable the roasting furnace to sway continuously and automatically. The support blocks and limiting rods can limit and fix the roasting furnace body.

Description

Technical Field

[0001] This utility model relates to the field of roasting furnace technology, and in particular to a roasting furnace for the extraction and recovery of palladium metal. Background Technology

[0002] A calcining furnace is a device used for high-temperature heating of powdered or filter cake materials. It is also called a calcining furnace. Based on the energy source used, it can be divided into four types: coal-fired furnaces, gas-fired furnaces, oil-fired furnaces, and electric heating furnaces. Based on the heating method, it is divided into two main categories: direct heating and indirect heating. Based on the operation method, it is divided into two types: continuous operation and intermittent operation. Calcination furnaces are mainly used in processes such as activation, crystal transformation, oxidation, pyrolysis, reduction, halogenation, and sulfation. They are widely used in the production of special materials in industries such as petrochemicals, inorganic chemicals, metallurgy, and construction. Calcination furnaces can also be used in the extraction of palladium.

[0003] However, in existing roasting furnaces, when heating palladium-containing waste, local overheating of the palladium-containing waste inside the furnace is prone to occur. Local overheating may lead to the volatilization and loss of palladium, thereby reducing the amount of palladium extracted. To address this issue, we propose a roasting furnace for palladium extraction and recovery. Utility Model Content

[0004] The purpose of this invention is to provide a roasting furnace for the extraction and recovery of palladium metal, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roasting furnace for palladium extraction and recovery includes a base plate. Two mounting plates are fixedly connected to the outer surface of the base plate. An electric push rod is fixedly mounted on the outer surface of each mounting plate. A support block is fixedly connected to the output end of each electric push rod. The outer surfaces of the two support blocks share a common roasting furnace body. A plurality of limiting holes are opened on the outer surface of the roasting furnace body. Two sets of limiting mechanisms are fixedly connected to the outer surface of the base plate. A plurality of heating elements are fixedly installed inside the roasting furnace body. A rotating mechanism is fixedly connected to the outer surface of the roasting furnace body.

[0007] In a further embodiment, the outer surface of the roasting furnace is connected to two gas guide pipes, and the outer surface of the roasting furnace is connected to a feed hopper.

[0008] In a further embodiment, an outlet pipe is fixedly connected to the outer surface of the roasting furnace, and a control valve is provided inside the outlet pipe. Two mounting plates are fixedly connected to the outer surface of the roasting furnace, and a temperature sensor is provided inside the roasting furnace body.

[0009] In a further embodiment, the limiting mechanism includes a fixed plate, and a plurality of limiting rods are slidably connected to the outer surface of the fixed plate. The outer surface of each limiting rod is adapted to the interior of a limiting hole. A bearing is fixedly embedded in the outer surface of the fixed plate, and a rotating rod is fixedly connected to the inner ring of the bearing. One end of the rotating rod is fixedly connected to the outer surface of the mounting plate.

[0010] In a further embodiment, the rotating mechanism includes a counterweight, the outer surface of which is fixedly connected to two elastic elements.

[0011] In a further embodiment, one end of each of the two elastic elements is fixedly connected to a spring block, and the outer surface of each spring block is fixedly connected to a damper, and one end of each damper is fixedly connected to the outer surface of the counterweight.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device utilizes heating elements to fully heat the interior of the roasting furnace, extracting palladium from palladium-containing fertilizers. A counterweight increases the weight on one side of the furnace, causing it to automatically sway under gravity, thus preventing localized overheating of the palladium-containing waste. Elastic components, spring-loaded blocks, and dampers ensure continuous automatic swaying of the furnace. Support blocks and limiting rods can then be used to limit and fix the furnace, stopping the swaying. This allows workers to easily discharge palladium from the furnace through control valves and discharge pipes, solving the problem of palladium volatilization loss due to localized overheating of palladium-containing waste, which reduces the amount of palladium extracted.

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.

[0022] Please see Figure 1-4In this utility model, a roasting furnace for extracting and recovering palladium metal includes a base plate 1. Two mounting plates 2 are fixedly connected to the outer surface of the base plate 1. An electric push rod 3 is fixedly installed on the outer surface of each mounting plate 2. A support block 4 is fixedly connected to the output end of each electric push rod 3. The outer surface of the two support blocks 4 is jointly provided with a roasting furnace body 5. Several limiting holes 6 are opened on the outer surface of the roasting furnace body 5. Two sets of limiting mechanisms 7 are fixedly connected to the outer surface of the base plate 1. Several heating elements 8 are fixedly installed inside the roasting furnace body 5. A rotating mechanism 9 is fixedly connected to the outer surface of the roasting furnace body 5. The roasting furnace body 5 can be supported by the provided support blocks 4.

[0023] Two gas guide pipes 10 are connected to the outer surface of the roasting furnace body 5, a feed hopper 11 is connected to the outer surface of the roasting furnace body 5, an outlet pipe 12 is fixedly connected to the outer surface of the roasting furnace body 5, a control valve 13 is installed inside the outlet pipe 12, two mounting plates 14 are fixedly connected to the outer surface of the roasting furnace body 5, and a temperature sensor 15 is installed inside the roasting furnace body 5. The temperature value inside the roasting furnace body 5 can be detected by the temperature sensor 15, which makes it easy for the staff to judge the extraction of palladium metal by heating time and temperature.

[0024] The limiting mechanism 7 includes a fixed plate 701. Several limiting rods 702 are slidably connected to the outer surface of the fixed plate 701. The outer surface of each limiting rod 702 is adapted to the interior of the limiting hole 6. A bearing 703 is fixedly embedded in the outer surface of the fixed plate 701. A rotating rod 704 is fixedly connected to the inner ring of the bearing 703. One end of the rotating rod 704 is fixedly connected to the outer surface of the mounting plate 14. The rotating mechanism 9 includes a counterweight 901. Two elastic elements 902 are fixedly connected to the outer surface of the counterweight 901. A spring block 903 is fixedly connected to one end of each elastic element 902. A damper 904 is fixedly connected to the outer surface of each spring block 903. One end of each damper 904 is fixedly connected to the outer surface of the counterweight 901. By using the counterweight 901, the roasting furnace body 5 can be automatically lowered.

[0025] The working principle of this utility model is as follows:

[0026] In use, first place the roasting furnace body 5 above the two support blocks 4. Then, insert the corresponding number of limiting rods 702 into the fixing plate 701 and insert one end of the limiting rod 702 into the limiting hole 6. At this time, the roasting furnace body 5 will be limited and fixed. Then, the waste containing palladium is poured into the roasting furnace body 5 through the feeding hopper 11, and a sealing cover is placed on top of the feeding hopper 11. Next, install the oxygen supply pipe and the exhaust pipe at one end of the two gas guide pipes 10 respectively. Then, pull out all the limiting rods 702 and operate the electric push rod 3 through the controller. The electric push rod 3 will drive the support blocks 4 to move, thereby releasing the limitation and fixing of the roasting furnace body 5. The heating element 8 is controlled by the controller to heat the inside of the roasting furnace body 5. At the same time, the heating element 8 presses down the counterweight 901. When the counterweight 901 moves downward, it will drive the roasting furnace body 5 to move downward, which will then drive the rotating rod 704 to rotate inside the bearing 703, and drive the pop-up block 903 to move downward. When the pop-up block 903 contacts the bottom plate 1, the elastic element 902 and the damper 904 will be squeezed and release their elasticity, thereby popping the counterweight 901 upward. This allows the roasting furnace body 5 to continuously rotate slightly and repeatedly, so that the waste containing palladium inside it will follow the rotation and shake, avoiding local heating of the waste.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
