example 1
[0033] Example 1: Add 3000Kg melamine alone
[0034] 1. Before feeding, first check whether the equipment is in good condition and clean, and check whether the amount of melamine in the feeding tank meets the requirements through the weighing module. If everything is ok go to the next step.
[0035] 2. Set the DCS system command, according to the command, 100% open the bottom valve below the feeding trough, and open the vibrating hammer at the same time, the frequency is 5S / time.
[0036] 3. The material starts to enter the first pipe chain 6. According to the DCS system command, the first transmission device 3 is turned on. According to the material characteristics, the power of the transmission device is automatically adjusted to 20% of the rated power.
[0037] 4. The material begins to enter the second pipe chain 7. According to the DCS system command, the second transmission device 4 is turned on. According to the change of the current in the first pipe chain 6, the powe...
example 2
[0048] Example two: 3300Kg melamine and 4500Kg solid formaldehyde are mixed together
[0049] 1. Before feeding, first check whether the equipment is in good condition and clean, and check whether the quantity of melamine and solid formaldehyde in the feeding tank meets the requirements through the weighing module. If everything is ok go to the next step.
[0050] 2. Set the DCS system command. According to the command, 100% open the bottom valve below the feeding tank, and at the same time open the vibrating hammer with a frequency of 5S / time, and open 65% of the bottom valve of the solid formaldehyde feeding tank.
[0051] 3. The material starts to enter the first pipe chain 6. According to the DCS system command, the first transmission device 3 is turned on. According to the material characteristics, the power of the transmission device is automatically adjusted to 28% of the rated power.
[0052] 4. The material starts to enter the second pipe chain 7. According to the DC...

Abstract
The invention relates to a fully enclosed solid material feeding system which comprises a feeding groove, a pipeline, a transmission device, a pipe chain, a control device and a reaction kettle, wherein the pipeline is a circulatory sealing pipeline; the pipe chain is mounted in the pipeline; the transmission device is mounted at the end part of the pipeline; a galvanometer is mounted on the transmission device; valves are respectively arranged on the feeding groove and the reaction kettle; a weighing module is mounted at the feeding groove and is linked with a feeding groove valve; the starting of the transmission device and the opening of the valves are controlled by using the control device; the pipe chain runs in a circulating manner in the sealing pipeline under the action of the transmission device; and after materials enter the pipe chain, the materials continuously enter the reaction kettle through the running of the pipe chain. According to the fully enclosed solid material feeding system, the materials can be conveyed in a fully enclosed manner, so that an environmental hazard caused by the fact that the materials are directly exposed in air is avoided. Therefore, with regards to materials which can not be exposed in the air, a reliable running environment is provided; and with regards to the materials with the poor liquidity, the materials can be conveyed safely. In addition, the fully automatic system is adopted, so that a great amount of manpower and a great quantity of material resources are saved.
Description
technical field [0001] The invention relates to a fully enclosed solid material feeding system and a feeding method, belonging to the technical field of chemical production. Background technique [0002] Traditionally, the transportation of solid materials includes many methods, for example, conveyor belts in coal mine production to transport coal lumps, and grain conveyor belts in large grain warehouses. But in chemical production, in many cases, these transportation methods are often not applicable. The main reasons are: [0003] 1. Some chemical raw materials are poisonous and harmful, and are not suitable for direct exposure to the air; [0004] 2. The particles of some chemical raw materials are small and have poor fluidity, and some are even as fine as flour; [0005] 3. Sometimes in production, various chemical raw materials are added in a certain proportion and quantity. [0006] Based on the above reasons, some traditional solid material transportation met...
