Description

Technical Field

[0001] This utility model relates to the field of carbonization furnace technology, specifically to a feeding mechanism for carbonization furnace material replenishment. Background Technology

[0002] The equipment used for carbonizing biomass raw materials is called a carbonization furnace. A carbonization furnace is a heating device used to convert organic or inorganic matter into carbon or carbonaceous compounds. It is also the core equipment in biomass carbonization, mainly used to convert various biomass raw materials into high-quality char products through high-temperature carbonization. It is widely used in many fields such as chemical industry, metallurgy, agriculture, forestry, energy production, soil improvement, and environmental protection.

[0003] The carbonization furnace mainly consists of a furnace chamber, heating system, condensation system, feeding system, combustion chamber, heating surface, slag removal system, and control system. Its working principle is as follows: A small portion of biomass material is first ignited in the furnace. The heat generated by combustion raises the internal temperature of the furnace to a certain level, thus achieving preheating. Once the furnace temperature reaches a certain level, the biomass material is added. Inside the furnace, the biomass material undergoes pyrolysis in a low-oxygen environment. After the internal moisture evaporates, deep decomposition pyrolysis products are produced, including solid char, gas, and liquid oil. During carbonization, the solid char adsorbs and stores some carbon elements through chemical reactions and physical adsorption. After the biomass material has pyrolyzed to a certain extent, the carbonization products are cooled and stored to prevent secondary combustion, further carbonization, or loss. A filtration device is usually installed at the furnace outlet to collect the gas and liquid oil from the carbonization products and to prevent ash from flying and polluting the environment.

[0004] In existing technologies, oil leakage from the drum valve of a carbonization furnace due to malfunctions necessitates frequent disassembly and maintenance, significantly increasing the workload of workers and reducing production efficiency. Therefore, to address these issues, this invention provides a feeding mechanism for carbonization furnace refueling. By replacing the drum valve with two slide gate valves and installing a hopper between them for material storage and refueling, this solution resolves the problems of oil leakage from the drum valve causing equipment malfunctions and production disruptions, while also addressing potential safety hazards in high-temperature environments. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for carbonization furnaces, so as to solve the problem that oil leakage from the drum valve of the carbonization furnace not only easily causes equipment failure and affects production, but also poses certain safety hazards in high-temperature environments.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a feeding mechanism for feeding a carbonization furnace, comprising a feeding bin, an inlet at the top of the feeding bin, an outlet at the bottom of the feeding bin, a gate valve detachably connected to the outlet, a feeding bin detachably connected to the gate valve, a rotating mechanism inside the feeding bin, the rotating mechanism comprising a bearing, the outer ring of the bearing being fixedly connected to the outer wall of one side of the feeding bin, a worm gear fixedly connected to the inner ring of the bearing, a motor being mounted on one end of the worm gear, a worm wheel meshing with the worm gear, a rotating shaft fixedly connected to the worm wheel, blades being mounted on the rotating shaft, and a feeding valve detachably connected to the bottom of the feeding bin.

[0007] The working principle of this utility model is as follows: When in use, first open the feeding valve and the gate valve to allow the material in the feeding hopper to enter the replenishment hopper from the discharge port, and then enter the carbonization furnace through the feeding valve; after the material is added, first close the feeding valve to allow the material in the feeding hopper to enter the replenishment hopper for storage; when the material height in the replenishment hopper reaches the upper limit of the replenishment hopper, close the gate valve; when the carbonization furnace needs a small amount of replenishment, open the feeding valve to distribute the material.

[0008] The beneficial effects of this utility model are as follows: By replacing the drum valve with a slide gate valve and setting a hopper on the slide gate valve and a rotating mechanism inside the hopper for storing materials and replenishing the carbonization furnace, this utility model solves the problem of equipment failure and production disruption caused by oil leakage from the drum valve of the carbonization furnace, while also replenishing the carbonization furnace and avoiding the safety hazards caused by oil leakage from the drum valve in high-temperature environments.

[0009] Option 2, which is a preferred option of the basic option, is that the gate valve is connected to both the discharge port and the feed hopper by flanges, and the feed hopper is connected to the feed valve by flanges. The flange connection method facilitates installation and disassembly by workers, and the simple operation provides convenience for inspection and maintenance.

[0010] Option 3, which is a preferred option of the basic option, is that both the gate valve and the feed valve are solenoid valves. The gate valve is electrically connected to a PLC controller, the feed valve is electrically connected to the PLC controller, and the motor is electrically connected to the PLC controller. The PLC controller can remotely control the opening and closing of the gate valve, the feed valve, and the motor, which is convenient for operators.

[0011] Option 4, which is a preferred option of the basic option, is that the replenishment hopper is equipped with a level gauge, which is electrically connected to the PLC controller; the level gauge can monitor the material height in the replenishment hopper in real time, and when the material height is lower than the set value, the gate valve can be opened by the PLC controller to replenish the replenishment hopper in time.

[0012] Option 5, which is a preferred option of the basic option, is provided with sealing gaskets at the connection between the gate valve and the discharge port and the replenishment hopper; the sealing gaskets increase the sealing between the gate valve and the discharge port and the replenishment hopper, preventing material leakage.

[0013] Option 6, which is a preferred option of the basic option, is a rotary valve. The rotary valve has good high temperature resistance and sealing performance, and can also play a role in uniform material feeding and prevent blockage during the feeding process.

[0014] Option 7, which is a preferred option of the basic option, has a door hinged to one side of the replenishment bin. Both the door and the replenishment bin are equipped with pin rings, and pins are embedded in the pin rings; this facilitates the maintenance of the rotating mechanism. Attached Figure Description

[0017] like Figure 1 and Figure 2As shown: A feeding mechanism for feeding a carbonization furnace includes a feeding bin 1, with an inlet 2 at the top and an outlet 3 at the bottom. A gate valve 4 is connected to the outlet 3 via a flange, and a sealing gasket 8 is provided at the connection between the gate valve 4 and the outlet 3. A feeding bin 5 is connected to the gate valve 4 via a flange, and a sealing gasket 8 is provided at the connection between the gate valve 4 and the feeding bin 5. A bin door 10 is hinged to one side of the feeding bin 5. Both the bin door 10 and the feeding bin 5 are provided with pin rings 11, and pins 12 are embedded in the pin rings 11. A rotating mechanism 9 is provided inside the feeding bin 5. The rotating mechanism 9 includes a bearing 91, and the outer ring of the bearing 91 is fixedly connected to the outer wall of one side of the feeding bin 5. The inner ring of bearing 91 is fixedly connected to a worm gear 92. A motor 93 is installed at one end of the worm gear 92. A PLC controller is electrically connected to the motor 93. A worm wheel 94 is meshed with the worm gear 92. A rotating shaft 95 is fixedly connected to the worm wheel 94. A blade 96 is installed on the rotating shaft 95. A level gauge 7, model CRPD-5X1000, is installed in the feeding bin 5. The level gauge 7 is electrically connected to the PLC controller. A feed valve 6 is connected to the bottom flange of the feeding bin 5. The feed valve 6 is a star-shaped discharge valve, model DXV-F26. Both the gate valve 4 and the feed valve 6 are solenoid valves. Both the gate valve 4 and the feed valve 6 are electrically connected to the PLC controller.

[0018] The implementation method of this embodiment is as follows: When it is necessary to add materials to the carbonization furnace, the feed valve 6 and the gate valve 4 are first opened by the PLC controller, so that the material in the feed bin 1 enters the replenishment bin 5 from the discharge port 3, and then enters the carbonization furnace through the feed valve 6; after the material is added, the feed valve 6 is first closed by the PLC controller and the motor 93 is turned on, so that the material in the feed bin 1 enters the replenishment bin 5. At the same time, the motor 93 drives the worm gear 92 to rotate, which in turn drives the worm wheel 94 to rotate the rotating shaft 95 and the blade 96. When the material level gauge 7 detects that the material height in the replenishment bin 5 reaches the upper limit of the replenishment bin 5, the gate valve 4 and the motor 93 are closed by the PLC controller. When the carbonization furnace needs a small amount of material replenishment, the feed valve 6 is opened to distribute the material. After the material replenishment is completed, the feed valve 6 is closed. When it is necessary to repair the rotating mechanism 9, the pin 12 is first moved upward so that the pin 12 leaves the pin ring 11. Then the bin door 10 is opened to repair the rotating mechanism 9.
