Description

Technical Field

[0001] This utility model relates to the field of industrial furnace and kiln technology, specifically to an industrial furnace and kiln with convenient material discharge. Background Technology

[0002] Industrial furnaces are equipment used for heating, calcining, and heat treatment of materials. They provide the required production temperature to the materials inside the furnace, which can change the properties of the materials and improve the efficiency of material processing. They are widely used in industrial production.

[0003] Currently, the furnace still has some shortcomings, such as material residue remaining at the bottom of the furnace that cannot be discharged.

[0004] To overcome the problem of material residue making discharge difficult, a prior art Chinese patent (publication number: CN206321064U) discloses a discharge device and a furnace having it. The scraper chain forms a ring and is wound around a first scraper sprocket and a second scraper sprocket. A drive assembly is connected to the first scraper sprocket and drives the first scraper sprocket to rotate, thereby rotating the scraper chain. Multiple scrapers are spaced apart circumferentially along the scraper chain. The scrapers at the lower part of the scraper chain can move up and down, allowing for flexible adjustment of their position. This enables the scrapers at the lower part of the scraper chain to adapt to the deformation of the furnace bottom and maintain contact with it, ensuring that all material at the furnace bottom is scraped out. This improves the heat transfer efficiency and utilization rate of the furnace using this discharge device, greatly enhancing its economic benefits.

[0005] However, the industrial furnaces currently in use still have certain shortcomings. The aforementioned document describes how scrapers scrape out the material from the bottom of the furnace to improve the heat transfer efficiency of the furnace. However, the material inside the furnace may deviate at an angle during transport, easily getting squeezed onto the side wall of the conveying device or getting stuck at the furnace outlet. Therefore, improvements to the existing structure are needed. Utility Model Content

[0006] The purpose of this invention is to provide an industrial furnace with convenient material discharge, in order to solve the problem mentioned in the background art that the material inside the furnace is easily transported and deviated, affecting the discharge efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an industrial furnace with convenient material discharge, comprising a furnace body, a support frame that runs through the interior of the furnace body, and a conveying roller that is rotatably connected to the inner side of the support frame.

[0008] The top of the support frame has four sets of guide grooves, and a guide block is slidably connected inside each guide groove. A push rod is fixed at the top of the guide block. The top of the support frame is equipped with a guide mechanism to improve the discharge efficiency of the furnace.

[0009] Furthermore, the guiding mechanism includes two fixed columns fixed to the top of the support frame, and rotating blocks are rotatably connected to the sides of the two fixed columns. The rotating blocks are connected to the sides of the rotating blocks with teeth, and the rotating blocks are engaged with the sides of the teeth of the push rod.

[0010] Furthermore, the rotating block is connected to a rotating rod at its end. Two sets of rotating rods are located at the feed inlet and discharge outlet of the furnace body, respectively. Five sets of rollers are rotatably connected inside the rotating rod, and an electric push rod is installed on the top of the support frame. The output end of the electric push rod is connected to the end of the push rod.

[0011] Furthermore, a base plate is fixed to the end of the rotating block near the rotating rod, a bottom groove is provided at the bottom of the rotating rod, and through grooves are provided on the sides of both the base plate and the bottom groove. A disassembly and assembly mechanism for easy cleaning of the rotating rod is provided at the end of the rotating block.

[0012] Furthermore, the disassembly and assembly mechanism includes a fixed block that slides through the through groove and the bottom groove, and a rotating block is rotatably connected to the bottom of the fixed block.

[0013] Furthermore, a limiting block is fixed at the bottom of the rotating block, and spring pieces are symmetrically connected to the upper surface of the limiting block. The spring pieces are locked to the positioning groove, which is located at the bottom of the fixed block.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This convenient industrial furnace can prevent material from accumulating inside the furnace body by activating an electric push rod. When its output end retracts, it pulls the push rod to move. The push rod drives four guide blocks to slide along the guide groove. At the same time, through the side meshing teeth, it can drive the rotating block to mesh and rotate around the fixed column. After the rotating block drives the rotating rod to rotate to a specified angle, when the material contacts the roller on the rotating rod, it can be aligned to ensure stable and efficient discharge.

[0015] 2. It is equipped with a push rod and a rotating block. The teeth on the side of the push rod and the rotating block can mesh and rotate, thereby driving the rotating rod to adjust the angle, realizing the guidance of materials inside the furnace and ensuring the stability of material conveying.

[0016] 3. It is equipped with rollers, which can prevent the material from contacting the rotating rod and generating excessive friction. The rotation of the rollers can further improve the efficiency of the rotating rod in guiding the material.

[0017] 4. A fixing block is provided to position the rotating rod and the base plate, which can improve the efficiency of disassembling and assembling the rotating rod and the rotating block, and facilitate the daily maintenance of the rotating rod. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, such as Figures 1-5The present invention provides the following technical solution to address the problem of material misalignment within the furnace, which affects discharge efficiency: A guiding mechanism is disclosed, comprising a furnace body 1, a support frame 2 internally connected to the furnace body 1, a conveying roller 3 rotatably connected to the inner side of the support frame 2, four sets of guide grooves 101 on the top of the support frame 2, a guide block 102 slidably connected inside each guide groove 101, a push rod 103 fixed to the top of the guide block 102, and a guiding mechanism to improve furnace discharge efficiency on the top of the support frame 2. The structure includes two fixed columns 105 fixed to the top of the support frame 2. Rotating blocks 104 are rotatably connected to the sides of the two fixed columns 105. The rotating blocks 104 are connected to the sides of the rotating blocks 104 and are engaged with the sides of the teeth of the push rod 103. A rotating rod 106 is connected to the end of the rotating blocks 104. The two sets of rotating rods 106 are located at the feed inlet and discharge outlet of the furnace body 1, respectively. Five sets of rollers 107 are rotatably connected inside the rotating rods 106. An electric push rod 108 is installed on the top of the support frame 2. The output end of the electric push rod 108 is connected to the end of the push rod 103.

[0022] When the kiln is in use, the material is conveyed to the kiln body 1 by the conveying roller 3 for heating and firing. To prevent the material from being pushed and unable to be conveyed inside the kiln body 1, the electric push rod 108 can be activated. When the electric push rod 108 is activated, its output end can retract. When the electric push rod 108 retracts, it can pull the push rod 103 to move. When the push rod 103 moves, it can drive the four guide blocks 102 to move. When the four guide blocks 102 move, they can slide through the guide groove 101. When the push rod 103 slides, the side teeth also move. The push rod 103 can then drive the rotating block 104 to mesh and rotate. When the rotating block 104 meshes and rotates, it can reach the fixed column 10. 5. When the rotating block 104 rotates, it can also drive the rotating rod 106 to rotate. When the rotating rod 106 rotates, it can adjust its angle. When the angle of the rotating rod 106 is adjusted, the inclined material will come into contact with the roller 107 when it is conveyed to the side of the rotating rod 106. When the roller 107 comes into contact with the material, it will rotate inside the rotating rod 106 due to friction. When the roller 107 rotates, it can reduce the frictional resistance caused by the material coming into contact with the rotating rod 106, which can improve the efficiency of material guidance. The guiding rotating rod 106 is distributed at the feed port and discharge port of the furnace body 1. After the rotating rod 106 is aligned with the material conveying position, it can ensure the stability and efficiency of material discharge.

[0023] Example 2, as follows Figures 5-7The present invention provides the following technical solution: In order to solve the problem that the rollers 107 of the furnace guide structure are easily blocked and affect the guiding efficiency, a disassembly and assembly mechanism is disclosed. The end of the rotating block 104 near the rotating rod 106 is also fixed with a base plate 201. The bottom of the rotating rod 106 is provided with a bottom groove 202. The sides of the base plate 201 and the bottom groove 202 are both provided with through grooves 203. The end of the rotating block 104 is provided with a disassembly and assembly mechanism for easy cleaning of the rotating rod 106. The disassembly and assembly mechanism includes a fixing block 204 that slides through the through groove 203 and the bottom groove 202. The bottom of the fixing block 204 is rotatably connected to a rotating block 205. The bottom end of the rotating block 205 is fixed with a limit block 206. The upper surface of the limit block 206 is symmetrically connected with spring pieces 207. The spring pieces 207 are locked to the positioning groove 208. The positioning groove 208 is opened at the bottom of the fixing block 204.

[0024] The firing process inside the furnace produces waste residue, which can easily clog the inner cavity between the roller 107 and the rotating rod 106. This causes friction when the roller 107 rotates, reducing its guiding efficiency. To mitigate this, when the rotating block 104 drives the fixed block 204 out of the top of the support frame 2, the limiting block 206 at the bottom of the fixed block 204 can be rotated. The rotation of the limiting block 206 causes the spring 207 to press against the inner wall of the positioning groove 208. When pressed, the spring 207 deforms due to its material, allowing it to be squeezed out of the positioning groove 208. At this time, the rotation of the limiting block 206 can drive the rotating block 205 to rotate. The rotating block 205 can rotate at the bottom of the fixed block 204. When the limiting block 206... When the cross-section of 06 coincides with the cross-section of the fixed block 204, the fixed block 204 can slide through the through groove 203 and the bottom groove 202. After the fixed block 204 slides out of the through groove 203, the rotating rod 106 is lifted. When the rotating rod 106 is lifted, it can drive the bottom groove 202 to move. When the bottom groove 202 moves, it can slide through the bottom plate 201. When the bottom groove 202 slides out of the surface of the bottom plate 201, the rotating rod 106 and the rotating block 104 will separate. After separation, the rotating rod 106 can be moved out of the furnace body 1 and taken to a designated position for rinsing. After rinsing, the inner cavity of the rotating rod 106 is prevented from being blocked, thereby ensuring the stability of the roller 107 rotating inside the rotating rod 106, and further ensuring the stability and efficiency of material discharge.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
