Description

Technical Field

[0001] This utility model relates to the field of fiberboard processing technology, specifically to a fiber slurry storage system for a fiber thermal grinding mill. Background Technology

[0002] The existing fiberboard production process includes processes such as wood chipping, hot grinding, drying, laying, and hot pressing. The hot grinding process is an indispensable and important step in fiberboard manufacturing, which preheats and steams the wood chips from the upstream and mechanically separates them into fibers. This process requires the use of a hot grinding mill, a high-energy-consuming piece of equipment (a single hot grinding mill has a power consumption of 1400KW, indicating that this equipment is a major power consumer). To save on electricity costs and respond to the national call for energy conservation and emission reduction (electricity prices fluctuate, with lower prices during off-peak hours and higher prices during peak hours; my country guides users to consume electricity during off-peak hours by widening the peak-valley price difference, thereby reducing electricity demand during peak hours and thus reducing overall energy consumption and carbon emissions), the hot grinding mill can be started during the daily off-peak hours (0:00-10:00 AM), and the hot-ground fiber pulp (enough for one day's use) can be stored in the material warehouse. This stored fiber pulp can then be used for subsequent fiberboard processing during the daytime start of production. However, the existing fiberboard production system is a continuous processing system and has problems such as not having a material unloading, storage, and transfer function, making it impossible to store the hot-ground fiber pulp in the material warehouse. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fiber slurry storage system for a fiber thermomill. It has the functions of feeding, storing and transferring materials, and can realize the storage of fiber slurry ground by the thermomill 1 during off-peak hours in the material warehouse for use during the day. It has a simple structure, saves electricity costs, responds to the national call for energy conservation and emission reduction, and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fiber slurry storage system for a fiber thermo-refining mill, comprising a thermo-refining mill, a cyclone separator and a screw conveyor mounted on a loading platform, wherein the discharge port of the thermo-refining mill is provided with a three-way valve, and the two discharge ports of the three-way valve are respectively connected to a discharge pipe and a cyclone separator pipe, the discharge pipe being used to send the thermo-refined fibers to the subsequent process; the cyclone separator pipe is connected to the inlet of the cyclone separator, and the screw conveyor is located at the discharge port at the bottom of the cyclone separator; the loading platform includes a cyclone separator support and a conveyor support, the cyclone separator being fixedly mounted on the cyclone separator support, and the screw conveyor being fixedly mounted on the conveyor support; the bottom end of the screw conveyor's auger cylinder is provided with multiple discharge pipes communicating with its conveying chamber, the discharge pipes being arranged along the axial direction of the screw conveyor, and the discharge pipes being used for unloading and loading.

[0005] Furthermore, the screw conveyor is a twin screw conveyor.

[0006] Furthermore, the rotary separator bracket and the conveyor bracket are arranged on the left and right sides, and both the rotary separator bracket and the conveyor bracket are provided with walking channels that correspond to each other.

[0012] Please see Figure 1-4 This utility model provides a technical solution: a fiber slurry storage system for a fiber thermo-refining mill, comprising a thermo-refining mill 1 installed on a thermo-refining mill tower 100, a cyclone separator 5 installed on a loading platform 7, and a screw conveyor 6. The thermo-refining mill 1 has a three-way valve 2 at its discharge port, with two discharge ports of the three-way valve 2 respectively connected to a discharge pipe 3 and a cyclone separator pipe 4. The discharge pipe 3 is used to send the thermo-refined fibers to subsequent processes. The cyclone separator pipe 4 is connected to the inlet of the cyclone separator 5, and the screw conveyor 6 is installed at the discharge port at the bottom of the cyclone separator 5. The loading platform 7 includes a cyclone separator support 71 and a conveyor support 72.

[0013] In use: During normal continuous production, the discharge port of the thermal mill 1 is connected to the discharge pipe 3 by controlling the three-way valve 2, and the discharge port of the thermal mill 1 is not connected to the cyclone separator pipe 4; the fiber pulp produced by the thermal mill 1 is sent to the equipment of the next process through the discharge pipe 3 for subsequent processing. When the hot mill 1 needs to be started during off-peak hours and the hot-milled fiber pulp needs to be stored in the material warehouse, the discharge port of the hot mill 1 is connected to the cyclone separator pipe 4 by controlling the three-way valve 2, and the discharge port of the hot mill 1 is disconnected from the discharge pipe 3. This allows the transfer truck 200 to move to the unloading pipe 61 to prepare for loading. The fiber pulp discharged from the discharge port of the hot mill 1 enters the cyclone separator 5 through the cyclone separator pipe 4. The cyclone separator 5 separates the high-temperature steam from the fiber pulp. The separated fiber pulp enters the screw conveyor 6. The cylinder 91 pulls the gate 92 to open the unloading pipe 61. The fiber pulp in the screw conveyor 6 falls into the transfer truck 200 through the unloading pipe 61.

[0015] Furthermore, the rotary separator bracket 71 and the conveyor bracket 72 are arranged on the left and right sides, and both the rotary separator bracket 71 and the conveyor bracket 72 are provided with walking channels and correspond to each other. A ladder 73 is provided on one side of the rotary separator bracket 71; a loading steel shed 8 is fixedly provided on the top of the conveyor bracket 72. The fiber pulp storage system for a fiber thermo-refining mill disclosed in this embodiment uses a loading platform 7 to support a cyclone separator 5 and a screw conveyor 6. The loading platform 7 is used for loading. By controlling a three-way valve 2, the discharge port of the thermo-refining mill 1 is connected to the cyclone separator 5, but not to the discharge pipe 3. The fiber pulp is fed into the screw conveyor 6 through the cyclone separator 5. After opening the discharge pipe 61, the fiber pulp in the screw conveyor 6 falls into the transfer truck 200 through the discharge pipe 61. The transfer truck 200 then transports the thermo-refined fiber pulp to the material warehouse for use during the day.
