Description

Technical Field

[0001] This utility model belongs to the field of industrial furnace technology, and in particular relates to a quantitative feeding structure for industrial furnaces. Background Technology

[0002] Industrial furnaces are key thermal equipment used in industrial production for heating, smelting, and heat treatment of materials. They are widely used in metallurgy, machinery, building materials, chemical industry and other fields. They generate heat through fuel combustion or electrical energy conversion to achieve material heating, phase change or performance modification. They are the core link in energy consumption and process control in industrial production processes, and their technical level directly affects production efficiency, product quality and environmental performance.

[0003] Future industrial furnaces will develop towards intelligence, low carbon emissions, high efficiency, and integration, while emphasizing modular design to adapt to the needs of flexible manufacturing. When an industrial furnace is in operation, the heating system is first started according to the process setting temperature, and the furnace temperature is monitored and adjusted through thermocouples and other means. After the furnace temperature stabilizes, the feeding structure is opened, and the material to be processed is fed into the furnace at a set rate to ensure that the material is heated evenly. The feeding process is coordinated with the gas pressure and temperature inside the furnace.

[0004] However, the existing feeding structure is not convenient for adjusting the quantity of material fed at one time during use, which makes it difficult for the equipment to cope with the diverse needs of different materials, thus affecting the stability of the production process.

[0011] Power components, including electric motors;

[0012] A winding assembly includes a winding reel and a connecting rope; the winding reel is drivenly connected to the motor; the connecting rope connects the winding reel and the base.

[0013] in,

[0014] When the adjusting plate slides relative to the feed box, it can drive the slider to slide inside the feed box, thereby changing the volume of one side of the hopper.

[0015] When the motor drives the winding wheel, the winding wheel pulls the bottom door to rotate via the connecting rope.

[0016] Furthermore, the adjusting part further includes a limiting component, which is installed on the side wall of the feed box;

[0017] The limiting component includes:

[0018] A connecting sleeve is fixedly connected to the right side of the feed box. A slider two is slidably connected to the inner wall of the connecting sleeve. A spring is fixedly connected inside the connecting sleeve, and the spring is connected to the slider two.

[0019] A snap-fit ​​component is mounted on the side of the slider two away from the spring via a connecting block; a limiting rod is provided on the side of the connecting block facing the spring;

[0020] The adjusting plate has several limiting grooves on the side facing the limiting rod;

[0021] in,

[0022] When the limiting rod is inserted into the limiting groove, the adjusting plate is in a fixed state;

[0023] After the limiting rod leaves the limiting groove, the adjusting plate is in a sliding state.

[0024] Furthermore, the plurality of the limiting grooves are linearly arranged along the sliding direction of the adjusting plate.

[0025] Furthermore, two limiting components are provided, both of which are located on the right side of the feed box.

[0026] Furthermore, the power assembly further includes:

[0027] A rotating shaft is rotatably connected to the inner wall of the feed box; the rotating shaft passes through the feed box; the end of the rotating shaft is driven to the winding wheel;

[0028] A bracket is fixedly mounted on the feed box and is on the same side as the rotating shaft.

[0029] The second rotating shaft is connected to the first bracket in a transmission manner;

[0031] The motor is fixedly connected to the bracket one, and the output shaft of the motor is connected to the rotating shaft two through a coupling; the outer wall of the rotating shaft two is fixedly connected to the gear one, and the gear one and gear two mesh with each other;

[0032] in,

[0033] Under the transmission action of the first gear and the second gear, the motor can drive the first rotating shaft and the winding wheel to rotate.

[0034] Furthermore, a guide member is provided on the side wall of the feed box on the same side as the winding reel; the guide member includes a second bracket, and a guide wheel is rotatably connected to the inner wall of the second bracket;

[0039] Compared with the prior art, the beneficial effects of this utility model are:

[0040] 1. By setting an adjustment part, the internal capacity of the feeding box can be flexibly adjusted. Specifically, pulling the connecting block can disengage the limiting rod from the limiting groove. At this time, pushing the limiting block can drive the adjustment plate to slide inside the feeding box, thereby dividing the internal space of the feeding box. After adjusting to the required capacity, releasing the connecting block will cause the spring force to make the limiting rod engage with the corresponding limiting groove, thus fixing the position of the adjustment plate. This achieves the effect of adjusting the capacity of the feeding box to adapt to the storage needs of different quantities of materials, thereby ensuring the stability of production.

[0041] 2. By setting up an opening and closing mechanism, the bottom of the feeding box can be opened and closed automatically. When it is necessary to pour out the material, the motor is started, and the drive shaft is rotated through the transmission of gear one and gear two, so that the winding wheel releases the connecting rope. The bottom door opens under the action of gravity, and the material is poured out. After the material is poured out, the motor reverses, the winding wheel winds up the connecting rope, and the bottom door is pulled up and closed under the guidance of the guide wheel and the action of the rotating block. This realizes the automatic control of the bottom of the feeding box, which improves the convenience and efficiency of operation. Attached Figure Description

[0058] A specific application of this embodiment is as follows: When it is necessary to adjust the capacity of the feed box 101, the connecting block 224 can be pulled, causing the slider 222 to slide within the connecting sleeve 221. At this time, the spring 223 will be stretched and generate elastic force. When the connecting block 224 is pulled, the limiting rod 225 will be pulled out of the limiting groove 226.

At this time, the capacity within the feed box 101 will be divided under the action of the slider 212. Then, the connecting block 224 can be released. At this time, under the action of the spring 223, the limiting rod 225 will be inserted into the corresponding limiting groove 226, thereby completing the adjustment. After adjustment, the material can be discharged from the hopper. 102 is poured into the feeding box 101. After it is full, the motor 314 can be started, causing its output shaft to drive the rotating shaft 313 to rotate. This, in turn, drives the rotating shaft 311 to rotate through the action of gear 315 and gear 316. When the rotating shaft 311 rotates, it will drive the winding wheel 321 to rotate. At this time, the connecting rope 323 will be unrestrained. Under the action of gravity of the bottom door 103, the bottom of the feeding box 101 will open, thus dumping out the material. After dumping is completed, the motor 314 can be started, causing its output shaft to reverse. At this time, the winding wheel 321 will rotate in the opposite direction, thus winding up the connecting rope 323. At this time, under the action of the guide wheel 325, the tension of the connecting rope 323 will be reversed. Under the action of the rotating block 322, the bottom door 103 will be pulled up, thus completing the closure.
