Description

Technical Field

[0001] This invention relates to the field of brick pressing technology, and more specifically, to an extrusion molding apparatus suitable for glazed bricks from coke ovens. Background Technology

[0002] As a core thermal equipment in industries such as metallurgy and chemical engineering, the performance of the refractory lining material in a coke oven directly determines the service life and production efficiency of the furnace. Coke oven glazed bricks, as an important type of lining brick, have a special glaze layer on their surface that effectively resists high-temperature chemical erosion and physical wear. Therefore, extremely high requirements are placed on the dimensional accuracy, structural density, and strength of the bricks. Extrusion molding is a key process in manufacturing these refractory bricks. This process uses immense pressure to compress powdered raw materials into a dense green body within a mold. Traditional extrusion molding equipment typically includes a feeding mechanism and a molding mechanism. The feeding mechanism is responsible for conveying a fixed amount of raw material to the mold in the molding mechanism, where it is then extruded by hydraulic components, and finally ejected by an ejector component.

[0003] Most existing extrusion molding equipment is equipped with automatic feeding mechanisms to replace traditional manual operation. Although this improves work efficiency, the unique powdery nature of the raw materials used for coke oven glazed bricks easily leads to adsorption and agglomeration. During the conveying and filling process, these raw materials often adhere to the inner wall of the hopper or the partition structure, resulting in uneven distribution. Especially when the filling hopper moves above the mold for filling, the raw materials accumulate and fail to be completely flattened, often resulting in some molding tanks being underfilled while other tanks are overfilled. This leads to inconsistent density and dimensional deviations in the extruded bricks, ultimately resulting in inconsistent product quality. Summary of the Invention

[0009] Preferably, the pushing part includes a first pushing unit and a second pushing unit arranged sequentially along the moving path of the filling hopper. The first pushing unit is located in the moving path segment before the bottom outlet of the filling hopper coincides with the top of the forming tank, and the second pushing unit is located in the moving path segment after the bottom outlet of the filling hopper coincides with the top of the forming tank. Both the first pushing unit and the second pushing unit are composed of multiple linearly distributed isosceles triangular pushing blocks.

[0010] Preferably, the pusher blocks in the first pusher unit are larger in size and spacing, used to drive the filling hopper to vibrate significantly to spread the raw material evenly; the pusher blocks in the second pusher unit are smaller in size and spacing, used to drive the filling hopper to vibrate at a small amplitude and frequency to promote the accurate falling of the raw material into the forming tank and to scrape off any excess material.

During the filling stage of aligning with the tank, it switches to small-amplitude high-frequency vibration. This not only effectively utilizes the vibration effect to shake off the raw materials adhering to the hopper wall and separator, ensuring sufficient filling, but also accelerates the falling process of the raw materials.

[0019] Please refer to the following: Figure 1 and Figure 2 An extrusion molding device for coke oven glazed bricks includes: a feeding mechanism 10 and a molding mechanism 20. The feeding mechanism 10 is located on one side of the molding mechanism 20 and is mainly used to automatically and quantitatively replenish raw materials to the molding mechanism 20. The molding mechanism 20 is used to extrude the raw materials into bricks of a preset shape.

[0020] The molding mechanism 20 includes a base 201, a molding die 202, a hydraulic assembly, and an ejection assembly. The hydraulic assembly includes a hydraulic cylinder 203 and an extrusion head 204. The hydraulic cylinder 203 is fixedly installed on the top of the base 201, and the extrusion head 204 is slidably disposed on the base 201, with its top end connected to the telescopic end of the hydraulic cylinder 203. The molding die 202 is fixedly installed on the base 201 and is disposed below the extrusion head 204. The molding die 202 is provided with multiple parallel, vertically penetrating molding grooves 2021, and the bottom of the extrusion head 204 is provided with an extrusion section adapted to the molding grooves 2021. The ejector assembly is located below the molding die 202. It includes a linear telescopic member 205 and an ejector head 206. The linear telescopic member 205 can be an electric push rod, a hydraulic cylinder 203, or a pneumatic cylinder. The ejector head 206 is fixed to the telescopic end of the linear telescopic member 205. The ejector head 206 includes multiple ejector portions that slide in cooperation with the lower end of the molding groove 2021.

[0021] Please refer to the following: Figures 2 to 6 The feeding mechanism 10 includes a frame 101, a feeding assembly, and a filling assembly. The feeding assembly includes a feeding hopper 102, a conveyor belt 103, and a discharge hopper 104. The feeding hopper 102 is fixedly installed at the top of the frame 101 and is mainly used for temporary storage of the required powdered raw materials. The conveyor belt 103 is horizontally fixedly installed on the frame 101, with its starting end located directly below the outlet of the feeding hopper 102. The discharge hopper 104 is fixedly installed at the end of the conveyor belt 103. The filling assembly includes a filling hopper 105, a linear drive source 106, a translational support, and a reciprocating drive. The filling hopper 105 is located at the top of the forming mold 202, with its bottom opening fitting flush with the top surface of the forming mold 202. When the filling hopper 105 is in its initial position, its top opening is directly below the outlet of the discharge hopper 104, used to receive the raw material discharged from the discharge hopper 104. The linear drive source 106 can be one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder 203, and is horizontally fixed on the frame 101, mainly used to drive the horizontal reciprocating motion of the filling hopper 105. The translation support includes two connecting rods 108 located on both sides of the filling hopper 105 and two guide rails 107 fixed on the forming mold 202. Both sides of the filling hopper 105 are slidably connected to the connecting rods 108 through elastic support members. Both ends of the connecting rods 108 are equipped with pulleys 109. The two pulleys 109 are respectively engaged with the guide rails 107 on the corresponding sides for rolling connection. The elastic support includes a slider 110, a slide rod 111, and a support spring 112. The slider 110 is fixed to the outside of the filling hopper 105. A groove 1081 is provided on one side of the connecting rod 108. The slide rod 111 is fixed in the groove 1081. One end of the slider 110 is slidably sleeved on the outside of the connecting rod 108, and its outside side slides in cooperation with the groove 1081. The support spring 112 is sleeved on the outside of the connecting rod 108, and its two ends contact the slider 110 and the inner wall of the groove 1081, respectively. The reciprocating drive includes a support arm 113, a mating roller 114, a first pushing unit, a second pushing unit, and a lifting drive source 118. The support arm 113 is slidably disposed on one side of the stuffing hopper 105, and the mating roller 114 is installed at the end of the support arm 113. The first and second pushing units are both disposed on the guide rail 107 near the mating roller 114. Both the first and second pushing units are composed of multiple linearly distributed isosceles triangular pushing blocks 115. The pushing blocks 115 are mainly used to generate lateral thrust on the mating roller 114, enabling the stuffing hopper 105 to move laterally. The first pushing unit is located in the first half of the moving path of the stuffing hopper 105. During the first half of the moving path, the first pushing unit... The bottom outlet of the filling hopper 105 has not yet overlapped with the top of the forming tank 2021; while the second pushing unit is located in the latter half of the moving path of the filling hopper 105. During this latter half, the bottom outlet of the filling hopper 105 begins to overlap with the top of the forming tank 2021. Compared with the pushing blocks 115 in the first pushing unit, the pushing blocks 115 in the second pushing unit are larger in size and spacing. The lifting drive source 118 can be an electric push rod, which is fixed on the outside of the filling hopper 105. Its telescopic end is connected to the support arm 113 and is used to drive the support arm 113 to move upward, so that the mating roller 114 can move upward and separate from the first pushing unit and the second pushing unit, avoiding contact with them. The inner side of the filling hopper 105 is provided with a partition 116, which is used to evenly divide the inner side of the filling hopper 105 into multiple filling storage areas. Each filling storage area corresponds exactly to the forming tank 2021. Therefore, the number of partitions 116 is set according to the number of forming tanks 2021. By adding partitions 116, when the filling hopper 105 is filled with raw materials into the forming tank 2021, each filling storage area corresponds exactly to one forming tank 2021, achieving precise filling and avoiding excessive accumulation of raw materials in areas outside the forming tank 2021.

[0022] Due to the aforementioned partition 116, when the raw material is introduced into the packing hopper 105 from the discharge hopper 104, a diversion occurs, causing the raw material to accumulate on the side of each packing storage area near the partition 116. This makes it difficult for the raw material to be evenly spread in the packing storage area. If the raw material has strong adsorption properties, even by simply driving the packing hopper 105 to move back and forth, some raw material may still be adsorbed. Therefore, to solve this problem, the present invention further optimizes the above solution, and the specific solution is as follows: Please refer to the following: Figure 7 and Figure 8Several evenly distributed drainage channels 1161 are provided on both sides of the partition 116. The drainage channels 1161 reduce the adhesion of raw materials to the inner wall of the filling hopper 105. Furthermore, multiple impact balls 117 at different suspension heights are suspended inside the partition 116. When the filling hopper 105 moves back and forth laterally, the impact balls 117 continuously impact the inner side of the partition 116, using the vibration generated by the impact to shake off the raw materials adsorbed on the inner wall of the filling hopper 105. Thus, through the combined arrangement of the drainage channels 1161 and the impact balls 117, the problem of raw material accumulation and adsorption can be further improved, allowing the raw materials to be spread as evenly as possible within the filling hopper 105, facilitating subsequent precise filling into the forming tank 2021.

[0023] The process of using the extrusion molding device of the present invention is as follows: First, the required powdered raw material is poured into the feeding hopper 102. The raw material is conveyed to the discharge hopper 104 via the conveyor belt 103 and discharged from the discharge hopper 104 into the filling hopper 105, which is in its initial position. During this process, because the filling hopper 105 is equipped with a separator 116, the raw material is diverted to each filling storage area. When the preset filling amount is reached, the conveyor belt 103 stops running. Then, the linear drive source 106 is started, which can drive the filling hopper 105 and the translation support to move together. The pulleys 109 at both ends of the connecting rod 108 begin to roll along the corresponding guide rails 107, allowing the filling hopper 105 to smoothly and gradually approach one side of the forming tank 2021. When the mating roller 114 moves to the position of the first pushing unit, the mating roller 114 first contacts the first pushing block 115 in the first pushing unit and is pushed by the pushing block 115. The entire filling hopper 105 begins to move horizontally synchronously. At this time, the slider 110 slides synchronously along the surface of the slider 111 and squeezes the support spring 112 to contract. When the mating roller 114 rolls to the middle end position of the pushing block 115, the filling hopper 105 reaches the displacement amount. Then, as the filling hopper 105 continues to move, under the elastic force of the support spring 112, the filling hopper 105 can be driven to gradually move horizontally and reset, and then continue to contact the next pushing block 115 until it completely passes through the first pushing unit. In the first half of the moving path, by driving the filling hopper 105 to move laterally multiple times, the raw materials filled inside can be shaken, so that the accumulated raw materials are evenly spread out. At the same time, the lateral movement of the filling hopper 105 also causes the impact balls 117 inside the separator 116 to continuously impact the inside of the separator 116. The vibration effect generated by the impact further shakes off the raw materials adsorbed on the separator 116, making the distribution of raw materials more uniform. In this way, the uniform spreading operation is automatically completed during the filling process without active intervention, which facilitates the subsequent filling operation. When the filling hopper 105 moves to the second push unit, the bottom outlet of the filling hopper 105 begins to align with the top of the forming tank 2021, and the raw material begins to fall into the forming tank 2021. Simultaneously, the roller 114 begins to contact the push block in the second push unit, causing the filling hopper 105 to move laterally again. Because the push blocks in the second push unit are smaller and more densely distributed, the filling hopper 105 operates in a high-frequency, small-amplitude lateral movement mode. This avoids the filling storage area in the filling hopper 105 moving too little laterally, resulting in a small misalignment with the forming tank 2021, allowing the raw material to fall precisely into the corresponding forming tank 2021 below. During this process, the lateral movement of the filling hopper 105 serves two purposes. First, it accelerates the falling speed of the raw materials and uses the vibration generated by the impact to shake off the adsorbed raw materials, ensuring that as much raw material as possible enters the forming tank 2021. This avoids the situation where only a portion of the raw materials fall due to adsorption between them, thus ensuring that a sufficient amount of raw materials are loaded into the forming tank 2021. Second, the reciprocating lateral movement of the bottom of the filling hopper 105 can scrape a small portion of the raw materials that have fallen onto the top surface of the forming mold 202 and are located outside the area of ​​the forming tank 2021 into the forming tank 2021. This not only reduces the accumulation of raw materials on the top surface of the forming mold 202, which would affect subsequent filling operations, but also avoids material waste. Then, when the filling storage area in the filling hopper 105 is completely aligned with the corresponding forming tank 2021, the forming tank 2021 can be filled with raw materials. At this time, the linear telescopic drive source stops extending and begins to retract, and the lifting drive source 118 begins to drive the support arm 113 to move upward, so that the mating roller 114 is higher than the first and second pushing units, so that when the filling hopper 105 moves and resets, the mating roller 114 no longer contacts the first and second pushing units. In this way, the filling hopper 105 will not perform lateral movement again. During the reset process of the filling hopper 105, the bottom of the connecting rod 108 scrapes the top surface of the raw material piled in the forming tank 2021, so that the raw material can be spread out until the filling hopper 105 moves to the initial position. The hydraulic assembly is activated, and the hydraulic cylinder 203 drives the extrusion head 204 downward. The extrusion section at the bottom of the extrusion head 204 enters the forming groove 2021 on the forming mold 202, extruding the raw material falling into the forming groove 2021 to form a brick of the preset shape. The extrusion head 204 then moves upward and resets. The ejection assembly is activated, and the linear telescopic component 205 drives the ejector head 206 upward. The ejector section on the ejector head 206 enters the lower end of the forming groove 2021, ejecting the formed brick from the forming groove 2021, completing the entire extrusion molding process. At this point, the operator can remove the ejected brick, start the conveyor belt 103 to replenish the raw material into the filling hopper 105, and repeat the above operation for the next round of brick extrusion molding.

[0024] As can be seen from the above, the extrusion molding apparatus provided by the present invention has the following advantages compared with traditional apparatus: To achieve precise quantitative filling and ensure uniform brick quality, the separator 116 inside the filling hopper 105 precisely divides its inner cavity into multiple independent filling zones corresponding one-to-one with the forming tank 2021. This ensures that the raw material can be directionally and independently loaded into each target tank, fundamentally avoiding the problems of misaligned filling or uneven filling volume between different tanks caused by raw material overflow. This results in bricks with highly consistent dimensions and density, improving product quality. To promote uniform spreading of raw materials and effectively reduce material adhesion: The unique reciprocating displacement drive component drives the filling hopper 105 to generate lateral vibration during its movement; in the first half of the filling path, the large-amplitude vibration loosens and evenly spreads the accumulated raw materials in each filling area; in the second half of the filling path (i.e., when the material is first discharged), the small-amplitude high-frequency vibration accelerates the falling of the raw materials and effectively shakes off the raw materials adhering to the hopper wall and the separator 116 using the vibration effect; combined with the diversion channel 1161 and the impact ball 117 on the separator 116, the combined effect greatly reduces the residue of raw materials and ensures the sufficiency and accuracy of the filling. Improving raw material utilization and keeping the mold surface clean: The high-frequency micro-lateral movement of the filling hopper 105 during the precision filling process also acts as a "scraper," scraping a small amount of raw material scattered on the mold surface and outside the forming tank 2021 into the corresponding tank. This process not only reduces raw material waste and improves utilization, but also automatically cleans the working surface of the mold, preventing residual raw materials from affecting the sealing and flatness of subsequent filling operations, reducing the frequency of manual cleaning, and ensuring the continuity of production. Improved automation and production efficiency: The entire process of feeding, spreading, filling, and scraping is completed automatically without human intervention; the device has an ingenious structural design, and each action is achieved through mechanical linkage, ensuring reliable operation and smooth process; it significantly improves the quantity and quality stability of bricks formed in a single batch, thereby greatly improving overall production efficiency, and is particularly suitable for the large-scale, high-quality production of coke oven glazed bricks.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
