Description

Technical Field

[0001] This utility model belongs to the field of tobacco technology, and specifically relates to a pretreatment device for preparing iron-manganese functional carbon-based materials. Background Technology

[0002] In the preparation of iron-manganese modified biochar, soluble iron and manganese salts are dissolved in water to prepare an iron-manganese salt solution. Crushed and sieved biomass raw materials are mixed with the iron-manganese salt solution and stirred continuously at 60℃-80℃ to ensure thorough mixing of the biomass raw materials, such as crop straw, with the solution. After mixing, the mixture is dried to obtain a biochar precursor material with iron and manganese salts uniformly distributed on the surface of the biomass raw materials. This biochar precursor material is then placed in a tube furnace for pyrolysis under an oxygen-limited atmosphere, followed by cooling to obtain iron-manganese modified biochar. Biochar has applications in agriculture, environmental remediation, and energy, among other fields. Biochar has excellent adsorption capacity for heavy metals and organic pollutants and is widely used in the remediation of contaminated soil and water bodies.

[0003] Currently, the preparation of biochar precursors for adsorbing iron and manganese requires a multi-step process, carried out in different equipment, which is labor-intensive, involves transfer during the process and results in losses, leading to low efficiency and reduced production capacity. Utility Model Content

[0004] In view of this, the present invention provides a pretreatment device for preparing iron-manganese functional carbon-based materials, which aims to solve the problems of the current method of preparing iron-manganese adsorbent biochar precursor materials, which requires step-by-step processing, operation in different equipment, large workload, transfer during the process, loss during the transfer, low work efficiency and reduced production capacity.

[0005] This utility model is implemented as follows:

[0006] This invention provides a pretreatment device for preparing iron-manganese functional carbon-based materials, comprising an outer casing, a filtrate outlet, a reaction chamber lifting rod, a slot, a stirring device, a reaction chamber, a pressurized gas inlet, a chamber heating wire, an exhaust port, a handle, and a control panel. The reaction chamber is housed inside the outer casing, and the side wall of the reaction chamber is tightly connected to the side wall of the outer casing. The reaction chamber is used for mixing and adsorbing materials. The filtrate outlet is located below one side wall of the outer casing and is connected to the side wall of the reaction chamber. The filtrate outlet is used to discharge the filtrate after the reaction; square openings are provided on the lower part of the left and right side walls of the outer casing, and the square openings are connected to the side walls of the reaction chamber; there are two reaction chamber lifting rods, which are respectively set in the square openings; a metal filter screen is provided at the bottom of the reaction chamber; the reaction chamber lifting rods are fixedly connected to the left and right ends of the metal filter screen respectively; the slots are fixedly provided on the side walls of the square openings, and the slots are used to fix the lifting rods of the reaction chamber after they are raised; the reaction chamber has an opening at the top.

[0007] Based on the above technical solution, the pretreatment device for preparing iron-manganese functional carbon-based materials of this utility model can be further improved as follows:

[0008] The reaction chamber is equipped with a stirring device, which includes a connecting rod and a stirring paddle. The upper wall of the outer chamber is provided with a pressurized gas inlet, which is used to pressurize and assist in the filtration of the filtrate.

[0009] Furthermore, heating wires are provided on the four side walls of the outer casing.

[0010] Furthermore, the rear wall of the outer casing is provided with the exhaust port.

[0011] The exhaust port can be switched on and off.

[0012] Furthermore, the handle is provided on the front wall of the outer casing, and the control panel is provided on the upper part of the front wall of the outer casing.

[0013] Furthermore, a temperature sensor is installed inside the stirring paddle.

[0014] Furthermore, the height of the card slot is 2 / 3 of the height of the square opening.

[0015] Furthermore, the upper end of the connecting rod passes through the upper wall of the reaction chamber and is fixedly connected to the upper wall of the outer chamber.

[0016] Furthermore, the height of the reaction chamber is 2 / 3 of the height of the outer chamber.

[0017] Furthermore, the size of the filter screen is adapted to the size of the bottom surface of the reaction chamber.

[0018] Compared with existing technologies, the beneficial effects of the pretreatment device for preparing iron-manganese functional carbon-based materials provided by this utility model are: it can prepare adsorbed carbon in batches. Currently, the preparation of biochar precursors for adsorbing iron and manganese requires steps in different devices, which is labor-intensive and results in losses during transfer. This device integrates the material mixing and adsorption processes into a single reaction chamber, located inside an outer chamber. This avoids transferring materials between different devices, reducing workload and transfer losses, thereby effectively improving work efficiency and increasing production capacity. A filtrate outlet is located on the lower side wall of the outer chamber, facilitating the discharge of the filtrate after the reaction. A pressurized gas inlet is located on the upper wall of the outer chamber, which can pressurize and assist in filtrate filtration, making filtrate discharge more efficient. A stirring device, including a connecting rod and a stirring paddle, is installed inside the reaction chamber to stir the materials, ensuring more uniform mixing and facilitating the mixing and adsorption process. Heating wires are installed on the four side walls of the outer chamber to heat the materials inside the reaction chamber, meeting the temperature requirements required for the reaction process. Meanwhile, a temperature sensor is installed inside the stirring paddle to monitor the temperature in real time, facilitating better control of the reaction temperature. An exhaust vent is located on the rear wall of the outer casing to expel gases generated during the reaction, ensuring pressure balance within the device and providing a favorable environment for the smooth progress of the reaction. A handle is located on the front wall of the outer casing for easy movement and operation of the device. A control panel is located above the front wall, allowing convenient control of various functions of the device (such as heating and stirring). Furthermore, the reaction chamber utilizes a lifting rod and a locking slot to facilitate maintenance and cleaning of components such as the filter screen at the bottom of the reaction chamber. The locking slot, with a height of 2 / 3 of the square opening height, effectively secures the lifting rod after the reaction chamber has been raised. This method solves the current problem of preparing biochar precursors for adsorbing iron and manganese requiring multiple steps in different equipment, resulting in a large workload, losses during transfer, low efficiency, and reduced production capacity.
