Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of brick presses, and more particularly to an extrusion forming device suitable for coke oven glazed bricks. BACKGROUND

[0002] As a core thermal equipment in metallurgical, chemical and other industries, the performance of the refractory lining in the coke oven directly determines the service life and production efficiency of the oven. As an important lining brick, the special glaze attached to the surface of the coke oven glazed brick can effectively resist high-temperature chemical corrosion and physical wear, so it puts forward very high requirements on the dimensional accuracy, structural density and strength of the brick body. Extrusion forming is a key process for manufacturing such refractory bricks, which presses the powdered raw materials into a dense billet in the mold through a huge pressure. The traditional extrusion forming device usually includes a feeding mechanism and a forming mechanism. The feeding mechanism is responsible for delivering a certain amount of raw materials to the mold of the forming mechanism, then the raw materials are extruded by a hydraulic assembly, and finally the formed brick body is ejected by an ejection assembly.

[0003] In the existing extrusion forming equipment, an automatic feeding mechanism is usually equipped to replace the traditional manual operation. Although this improves work efficiency, the unique powder-like characteristics of the raw materials used for coke oven glazed bricks can easily cause adsorption and agglomeration; during the conveying and filling process, such raw materials often adhere to the inner wall or partition structure of the hopper, resulting in uneven distribution; especially when the hopper is moved above the mold for filling, due to the accumulation of raw materials, it cannot be completely flattened, often resulting in the situation that some forming grooves are short of filling while others are overfilled, thus leading to inconsistent density and size deviation of the extruded bricks, ultimately resulting in uneven product quality.

[0041] The inside of the filling hopper 105 is provided with a partition body 116, the partition body 116 is used for uniformly dividing the inside of the filling hopper 105 into a plurality of filling storage areas, each filling storage area is correspondingly arranged with the forming groove body 2021, and therefore the number of the partition body 116 is set according to the number of the forming groove body 2021; by additionally arranging the partition body 116, when the filling hopper 105 fills the raw materials into the forming groove body 2021, each filling storage area is correspondingly arranged with one forming groove body 2021, so that precise filling is realized and excessive accumulation of the raw materials in the area outside the forming groove body 2021 is avoided.

[0042] Due to the arrangement of the above-mentioned partition body 116, when the discharge hopper 104 guides the raw material into the filling hopper 105, the raw material will be divided into two parts, and the raw material will be accumulated on the side of each filling storage area close to the partition body 116, which makes it difficult to evenly spread the raw material in the filling storage area, and if the raw material has strong adsorption, only by driving the filling hopper 105 to reciprocate transversely, part of the raw material may still be adsorbed, therefore, in order to solve this problem, the present application is based on the above-mentioned scheme, and the specific scheme is as follows:

[0043] Please refer to Figure 7 and Figure 8 , a plurality of uniformly distributed drainage grooves 1161 are arranged on both sides of the partition body 116, which can reduce the adhesion of the raw material on the inner wall of the filling hopper 105, and a plurality of impact balls 117 with different suspension heights are hung in the partition body 116; when the filling hopper 105 reciprocates transversely, the impact balls 117 can continuously impact the inner side of the partition body 116, and the raw material adsorbed on the inner wall of the filling hopper 105 can be shaken off by using the vibration effect generated by the impact. In this way, through the cooperation of the drainage grooves 1161 and the impact balls 117, the problems of raw material accumulation and adsorption can be further improved, so that the raw material can be as evenly spread as possible in the filling hopper 105, so as to facilitate subsequent accurate filling into the forming groove body 2021.

[0044] The use process of the extrusion molding device is as follows:

[0045] Firstly, the required powder raw material is poured into the feeding hopper 102, and the raw material is conveyed to the discharge hopper 104 by the conveying belt 103, and then discharged from the discharge hopper 104 into the filling hopper 105 in the initial position. In this process, since the filling hopper 105 is internally provided with a partition body 116, the raw material will be divided into two parts, and when the preset filling amount is reached, the conveying belt 103 stops running; then, the linear driving source 106 is started, which can drive the filling hopper 105 and the translation support to move, and the pulleys 109 at both ends of the connecting rod 108 start to roll along the corresponding guide rails 107, so that the filling hopper 105 gradually approaches the forming groove body 2021 stably;

[0046] When the matching roller 114 is matched to the first pushing unit position, the matching roller 114 first contacts the first pushing block 115 in the first pushing unit and is pushed by the pushing block 115, and the whole filling hopper 105 starts to move synchronously, at this time, the sliding block 110 moves synchronously along the surface of the sliding rod 111 and extrudes the supporting spring 112 to contract, when the matching roller 114 rolls to the middle end position of the pushing block 115, the filling hopper 105 reaches the displacement amount, and then continues to move, under the elastic force of the supporting spring 112, the filling hopper 105 is driven to gradually move back and forth, and then continues 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 back and forth multiple times, the raw materials filled in the filling hopper 105 can be shaken, so that the stacked raw materials are evenly spread, and at the same time, the movement of the filling hopper 105 also makes the impact balls 117 inside the partition body 116 continuously impact the inside of the partition body 116, and the raw materials adsorbed on the partition body 116 are further shaken off by the impact vibration effect, so that the raw materials are more evenly distributed; in this way, the uniform paving work is automatically completed during the filling process, without active intervention, which is convenient for subsequent filling work.

[0047] When the filling hopper 105 moves to the second pushing unit, the bottom outlet of the filling hopper 105 starts to coincide with the top of the forming groove body 2021, and the raw materials start to fall into the forming groove body 2021, and at the same time, the matching roller 114 starts to contact the pushing block in the second pushing unit, so that the filling hopper 105 moves back and forth again. Since the pushing block in the second pushing unit is smaller in size and more densely distributed, the filling hopper 105 is in a high-frequency small-amplitude back-and-forth movement mode at this time, which can avoid the small-amplitude back-and-forth movement of the filling hopper 105 and the small-magnitude misalignment between the filling hopper 105 and the forming groove body 2021, so that the raw materials can be accurately dropped into the corresponding forming groove body 2021 below. At this time, through the back-and-forth movement of the filling hopper 105, on the one hand, it is to speed up the falling speed of the raw materials, and to shake off the adsorbed raw materials by the impact vibration, so that as many raw materials as possible enter the forming groove body 2021, to avoid the adsorption between the raw materials and only part of the raw materials falling, so as to ensure that enough raw materials are loaded into the forming groove body 2021; on the other hand, the back-and-forth movement of the bottom of the filling hopper 105 can scrape the small part of the raw materials that fall on the top surface of the forming die 202 outside the forming groove body 2021 into the forming groove body 2021, which not only reduces the accumulation of raw materials on the top surface of the forming die 202 to affect the subsequent filling work, but also avoids waste of raw materials;

[0048] Then, when the filling material storage area in the filling hopper 105 is completely aligned with the corresponding forming groove body 2021, the forming groove body 2021 can be filled with raw materials, at this time, the linear extension drive source stops elongation and starts contraction, and the lifting drive source 118 starts to drive the support arm 113 to move upwards, so that the matching roller 114 is higher than the first and second pushing units, so that the matching roller 114 is no longer in contact with the first and second pushing units when the filling hopper 105 moves back, so that the filling hopper 105 will not move horizontally again, and during the resetting process of the filling hopper 105, the bottom of the connecting rod 108 is scraped on the top surface of the raw material accumulated in the forming groove body 2021, so that the raw material can be laid flat until the filling hopper 105 moves to the initial position;

[0049] Start the hydraulic assembly, the hydraulic cylinder 203 drives the extrusion head 204 to move downward, the extrusion part at the bottom of the extrusion head 204 enters the forming groove body 2021 on the forming mold 202, and the raw material falling into the forming groove body 2021 is extruded to form a brick body with a predetermined shape, and the extrusion head 204 moves upward to reset; start the ejection assembly, the linear extension part 205 drives the ejection head 206 to move upward, the ejection part on the ejection head 206 enters the lower end of the forming groove body 2021, and the formed brick body is ejected from the forming groove body 2021, and the whole extrusion molding process is completed. At this time, the operator can take away the ejected brick body, start the conveyor belt 103, start to supplement the raw materials into the filling hopper 105, repeat the above operation, and carry out the next round of brick extrusion molding work.

[0050] As can be seen from the above, the extrusion molding device provided by the application has the following advantages compared with the traditional device:

[0051] Realize accurate quantitative filling, ensure the uniformity of brick quality: the partition body 116 arranged in the filling hopper 105 accurately divides the inner cavity into multiple independent filling areas corresponding to the forming groove body 2021. It ensures that the raw material can be loaded into each target groove body directionally and independently, fundamentally avoids the problem of filling misalignment or uneven filling amount between different grooves caused by raw material flowing, and can make the finally extruded brick body have highly consistent size and density, improving the quality of the product;

[0052] Promote uniform spreading of raw materials, effectively reduce adhesion of raw materials: the unique reciprocating displacement drive element drives the filling hopper 105 to produce lateral shaking during movement; in the first half of the filling path, the accumulated raw materials are loosened and uniformly spread in each filling area through large amplitude shaking; in the second half of the filling path (i.e. when the raw materials start to fall), through small amplitude high frequency shaking, the falling of the raw materials is accelerated, and the raw materials adhered to the wall of the hopper and the partition body 116 are effectively shaken off by the vibration effect; combined with the drainage groove 1161 and the impact ball 117 on the partition body 116, the two work together to greatly reduce the residual raw materials, ensuring the fullness and accuracy of the filling;

[0053] Increase raw material utilization and keep the mold surface clean: The high-frequency and small lateral movement of the filling hopper 105 during the precise filling process also acts as a "scraper", which can scrape a small amount of raw material scattered on the mold surface and outside the forming groove body 2021 into the corresponding groove body. This process not only reduces waste and improves utilization, but also automatically cleans the mold working surface, avoiding the impact of residual raw materials on the sealing and flatness of subsequent filling operations, reducing the frequency of manual cleaning, and ensuring the continuity of production.

[0054] Improve the degree of automation and production efficiency: The entire process of feeding, spreading, filling and scraping does not require manual intervention and is automatically completed. The device structure is cleverly designed, and each action is achieved through mechanical structure linkage, which is reliable and smooth in operation. It significantly improves the number and quality stability of single-formed brick bodies, thereby greatly improving the overall production efficiency, and is particularly suitable for large-scale and high-quality production of coke oven glazed bricks.

[0055] The embodiments of the application are described above, but the application is not limited to the specific embodiments described above, which are only illustrative and not limiting. Those skilled in the art can make many forms under the inspiration of the application, which are all within the protection of the application.
