Description

Technical Field

[0001] This utility model relates to the field of preheating furnace technology, and more specifically, to a preheating furnace that facilitates material handling. Background Technology

[0002] Expanded perlite is a white granular material with a honeycomb structure, produced by preheating and rapidly heating perlite ore to a high temperature. The principle is as follows: perlite ore is crushed into sand of a certain particle size, then preheated and rapidly heated to over 1000°C. The moisture in the sand vaporizes and expands within the softened, glassy sand, forming a porous structure and increasing in volume by 10-30 times. Perlite is classified into three forms based on its expansion process and application: open-cell, closed-cell, and hollow-cell. Current preheating furnaces use manual feeding, which makes feeding difficult and negatively impacts furnace efficiency.

[0003] To address the above issues, application number 20240332255.7, entitled "A Preheating Furnace for Easy Material Loading and Unloading," describes a furnace body. A heater is fixedly installed on the inner wall of the furnace body. A servo motor is fixedly installed on the bottom surface of the furnace body via a frame. A groove is formed on the right side of the furnace body. Bearings are fixedly embedded in the inner top and bottom walls of the groove. The inner rings of two bearings are jointly connected to a threaded shaft. A limit groove is formed on the inner wall of the groove. This preheating furnace for easy material loading and unloading, through the cooperation of the threaded shaft and the threaded sleeve, enables automated feeding of the hopper, thereby reducing the workload of workers and increasing the feeding speed of the device. Through the cooperation of the electric telescopic rod and the push plate, the material can be easily pushed into the melting furnace, thus achieving the effect of easy feeding. The cooperation of the bearings and the servo motor provides the necessary power for the device, avoiding the phenomenon of being unable to adjust.

[0004] Although the device has many beneficial effects, it still has the following problems: When feeding materials, the device uses a feeding hopper to lift the materials up and then uses an electric telescopic rod in conjunction with a push plate to put the materials into the preheating tank. However, this method of putting a large amount of materials into the preheating tank at the same time makes it difficult for the materials to be heated evenly, and the preheating effect is easily affected by the large accumulation of materials.

[0005] Secondly, after the material is preheated, the device only uses a discharge pipe to discharge the melted material inside. This discharge method is often difficult to discharge the material quickly, and sometimes the discharge port is too narrow, which can cause blockage. This undoubtedly causes great trouble in actual use.

[0006] In view of this, we propose a preheating furnace that facilitates material handling. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of this invention is to provide a preheating furnace that facilitates material handling, in order to solve the problems mentioned in the background art.

[0009] 2. Technical Solution

[0010] A preheating furnace for easy material handling includes a support plate, a rotary motor and a controller are provided on one side wall of the support plate, a fixing plate is provided on the top of a plurality of support plates, a material handling assembly is connected between the plurality of fixing plates, the material handling assembly includes a feeding bucket, and a preheating assembly is connected to the output end of the rotary motor, the preheating assembly includes a rotating box.

[0011] Preferably, a weighing sensor is provided on the top of the feeding bucket, the output end of the weighing sensor is connected to a connecting frame, a weighing bucket is provided at the bottom of the connecting frame, and an electric control valve is provided at the bottom of the weighing bucket.

[0012] Preferably, a suction pump is provided on the side wall of the feeding bucket, the output end of the suction pump is connected to a pipe, and the end of the pipe is connected to a suction pipe.

[0013] Preferably, the rotating box is filled with an insulation layer, a fixed bucket is fixedly fitted inside the rotating box, and a drive motor is provided at the bottom of the rotating box.

[0014] Preferably, the output end of the drive motor extends into the interior of the fixed barrel and is connected to a rotating platform. A rotating toothed seat is rotatably connected to the top of the rotating platform, and a placement barrel is provided on the top of a plurality of rotating toothed seats.

[0015] Preferably, the top of the fixed barrel is provided with a cover plate, the top of the cover plate has a feed inlet, and the top of the feed inlet is threaded with a sealing cap.

[0016] Preferably, a heating rod is sleeved inside the outer wall of the fixed barrel, and the inner wall of the fixed barrel is provided with toothed grooves that mesh with the plurality of rotating toothed seats.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of this utility model are as follows: When feeding materials, the suction pump and suction pipe can be used to transport the materials to the weighing tank inside the feeding tank. At this time, the weighing sensor will weigh the materials. After the materials reach a certain measurement, the electric control valve opens and the materials are fed into the designated placement tank. Then, the materials are fed into other placement tanks in batches using the same method. The multiple placement tanks can be rotated and adjusted by the drive motor. After the materials enter the multiple placement tanks in batches, the drive motor will also drive the rotating table to rotate. During the rotation, the rotating toothed seats at the bottom of the multiple placement tanks can mesh with the inner wall of the fixed tank, so that the multiple placement tanks can rotate on their own axis while revolving around the central axis. The combination of rotation and revolution of the placement tanks can make the materials continuously tumble and mix in the placement tanks, ensuring that the materials in all parts can fully contact the heat source, avoiding local overheating or overcooling, thereby achieving a more uniform preheating effect. At the same time, this movement mode also increases the contact area and contact time between the materials and the hot air, further improving the heating efficiency.

[0019] After the material is preheated, the rotating box can be tilted by the drive of the rotary motor. Then, the sealing cover is opened, and the drive motor is started to make multiple placement buckets revolve. Whenever a placement bucket aligns with the feed inlet, the material inside the placement bucket will be discharged. This discharge method can speed up the material discharge and effectively reduce the possibility of blockage at the discharge port due to narrow outlets. This effect is achieved because the revolving motion of multiple placement buckets gives the material a certain centrifugal force when it is discharged, which helps the material to quickly leave the placement bucket. Moreover, the discharge when the placement bucket aligns with the feed inlet ensures that the direction and position of the material discharge are more accurate, avoiding the accumulation and blockage of material at the discharge port. At the same time, this batch-by-batch, regular discharge method also makes the entire discharge process more stable and efficient. Attached Figure Description

[0031] In some embodiments: the weighing sensor model 210 can be a Mettler Toledo TSH series, and the electric control valve model 240 can be a 0820058076 series (Aventics brand). Both of these are existing technologies, which facilitate accurate proportioning of materials and material discharge operations.

[0032] Furthermore, a suction pump 250 is provided on the side wall of the feeding tank 200, and a pipe 260 is connected to the output end of the suction pump 250. A suction pipe 270 is connected to the end of the pipe 260.

[0034] In some embodiments, the insulation layer 310 is made of glass wool, which facilitates the insulation of the temperature inside the preheating barrel.

[0035] Furthermore, the output end of the drive motor 320 extends into the fixed barrel 330 and is connected to a rotary table 340. The top of the rotary table 340 is rotatably connected to a rotating toothed seat 350. The top of the multiple rotating toothed seats 350 is provided with a placement barrel 360, which facilitates better revolution and rotation of the placement barrel 360.

[0036] It is worth noting that the top of the fixed bucket 330 is provided with a cover plate 370, the top of the cover plate 370 is provided with a feed inlet 380, and the top of the feed inlet 380 is threaded with a sealing cap.

[0041] Working Principle: When feeding materials, the powerful suction pump 250 and suction pipe 270 are fully utilized to efficiently transport the materials into the weighing bin 230 inside the feeding bin 200. At this time, the weighing sensor 210 immediately weighs the materials. When the material reaches the specific metering requirement, the electric control valve 240 quickly opens, accurately placing the materials into the designated placement bin 360.

After the materials enter multiple placement bins 360 in batches, the drive motor 320 also drives the rotating table 340 to rotate. During the rotation process, multiple... The rotating toothed seat 350 at the bottom of the placement tank 360 can be tightly engaged with the inner wall of the fixed tank 330 for transmission.

After the material is preheated, the rotating box 300 can be rotated and tilted by the rotary motor 110. Then, the sealing cover is opened and the drive motor 320 is started to drive multiple placement tanks 360 to revolve around the center. Whenever a designated placement tank 360 corresponds to the feed port 380, the material inside the placement tank 360 will be discharged smoothly. Using this discharge method, the material discharge speed can be accelerated on the one hand, and the blockage of the discharge port due to the narrow discharge port can be effectively reduced on the other hand.
