Description

Technical Field

[0001] This utility model relates to the technical field of refractory brick production equipment, specifically to a vibrating device for producing high-density magnesium-iron-aluminum spinel sand bricks. Background Technology

[0002] Magnesium iron aluminum spinel sand bricks are characterized by low thermal conductivity and possess excellent mechanical properties, high-temperature resistance, and corrosion resistance. During production, high-purity magnesia, fused magnesia, fused iron aluminum spinel, α-Al₂O₃ micro powder, metallic iron powder, metallic aluminum powder, and composite binders are typically blended together and then formed into multi-layer composite magnesium iron aluminum spinel sand bricks using molding equipment.

[0003] CN 221937067 U discloses a magnesia-carbon brick forming and processing device, which includes a processing device base, a pounding mechanism located on top of the processing device base, and a rapid forming mechanism located inside the processing device base. The processing device base has a processing groove inside; the pounding mechanism includes a mounting plate, and a second buffer spring is connected to the bottom of the mounting plate. This device, through the pounding mechanism, activates a hydraulic cylinder to drive a lifting plate and a pounding plate downwards, while simultaneously activating a vibration motor to drive the pounding plate to vibrate and pound, uniformly transmitting pressure to the raw material. The material becomes more compact after being subjected to force. Combined with the second buffer spring, telescopic rod, and telescopic rod sleeve, while ensuring the up-and-down movement of the pounding plate, the vibration frequency of the pounding plate is increased, which helps to improve pounding efficiency and facilitates rapid forming. However, the following problem still exists: only one brick is formed at a time, making it unsuitable for simultaneously vibrating and pounding multiple bricks. Utility Model Content

[0004] The purpose of this invention is to provide a vibratory compaction device for the production of high-density magnesium-iron-aluminum spinel sand bricks that has a reasonable structure and reliable use, thereby significantly improving production efficiency.

[0005] The technical solution of this utility model is:

[0006] A vibratory compaction device for producing high-density magnesium-iron-aluminum spinel sand bricks includes a base plate, a left support and a right support mounted on the upper surface of the base plate, and a forming seat between the left and right supports. The key technical features are: a guide block is fixed between the tops of the left and right supports; a lifting assembly is mounted on the guide block; a filter support plate is fixed to the lower part of the lifting assembly; an air chamber is provided inside the filter support plate; a compressed gas connector communicating with the air chamber is provided on the outer side of the filter support plate; and multiple hollow pressure blocks are fixed to the lower surface of the filter support plate. The hollow pressure block has corresponding vent holes on its top surface and the filter support plate on its lower surface. The vent holes connect the air chamber and the inner cavity of the hollow pressure block. A return spring is fixed to the inner top surface of the hollow pressure block. A linkage plate is fixed to the lower end of the return spring. Small support pillars are fixed to the four corners of the lower surface of the linkage plate. The bottom surface of the hollow pressure block has clearance holes corresponding to the small support pillars. The lower ends of the four small support pillars pass through the corresponding clearance holes and are connected and fixed to the same pressure plate. The upper surface of the forming base has forming grooves that correspond one-to-one with each pressure plate.

[0007] The aforementioned vibrating equipment for producing high-density magnesium-iron-aluminum spinel sand bricks has multiple longitudinal guide holes on the guide block, and the lifting assembly consists of guide columns located in the longitudinal guide holes, connecting plates connected to the upper ends of each guide column, and lifting plates connected to the lower ends of each guide column.

[0008] In the aforementioned vibrating equipment for producing high-density magnesium-iron-aluminum spinel sand bricks, each of the hollow compaction blocks is arranged in a rectangular matrix on the lower surface of the filter support plate.

[0009] The aforementioned vibratory equipment for producing high-density magnesium-iron-aluminum spinel sand bricks has a wear-resistant layer on the inner wall of the bypass through hole.

[0010] The above-mentioned vibrating equipment for producing high-density magnesium-iron-aluminum spinel sand bricks has a lifting cylinder below the forming base. A push plate is fixed to the upper end of the cylinder rod of the lifting cylinder. A top material plate is embedded in the bottom surface of the forming groove. A top material rod passing through the bottom surface of the forming base is provided on the bottom surface of the top material plate. The lower end of each top material rod is connected and fixed to the push plate.

[0011] The beneficial effects of this utility model are:

[0012] Compressed air is introduced into the air chamber of the filter support plate at a set frequency, overcoming the tension of the return spring and pushing the linkage plate inside each hollow pressure block downwards. The pressure plate moves downwards with the linkage plate, and after the thrust of compressed air is lost, the return spring drives the linkage plate and pressure plate upwards to return to their original positions. This up-and-down reciprocating motion produces a tamping and pressing effect. At the same time, each hollow pressure block is concentrically aired and acts on multiple pressure plates, which can simultaneously tamp and press the raw materials in each forming tank, significantly improving production efficiency.

[0016] The present invention will be described in detail with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, the vibrating equipment for producing high-density magnesium-iron-aluminum spinel sand bricks includes a base plate 15, a left support 1 and a right support 14 disposed on the upper surface of the base plate 15, and a forming seat 7 disposed between the left and right supports.

[0018] In this embodiment, a guide block 2 is fixed between the tops of the left support 1 and the right support 14, and a lifting assembly is provided on the guide block 2. In this embodiment, the guide block 2 has multiple longitudinal guide holes, and the lifting assembly consists of guide posts 4 disposed in the longitudinal guide holes, connecting plates 3 connected to the upper ends of each guide post 4, and lifting plates 5 connected to the lower ends of each guide post 4. A filter support plate 13 is fixed to the lower surface of the lifting plate 5 of the lifting assembly. An air chamber 16 is provided inside the filter support plate 13, and a compressed gas connector 6 communicating with the air chamber 16 is provided on the outer side of the filter support plate 13.

[0019] Multiple hollow pressure blocks 18 are fixed to the lower surface of the filter support plate 13. In this embodiment, the hollow pressure blocks 18 are arranged in a rectangular matrix on the lower surface of the filter support plate 13. Corresponding vent holes 17 are provided on the top surface of the hollow pressure blocks 18 and the lower surface of the filter support plate 13. The vent holes 17 connect the air chamber 16 and the inner cavity of the hollow pressure block 18. A return spring 19 is fixed to the inner top surface of the hollow pressure block 18. A linkage plate 22 is fixed to the lower end of the return spring 19. Small support pillars 20 are fixed to the four corners of the lower surface of the linkage plate 22. The bottom surface of the hollow pressure block 18 has clearance holes corresponding to the small support pillars 20. The lower ends of the four small support pillars 20 pass through the corresponding clearance holes and are connected and fixed to the same pressure plate 21. In this embodiment, a wear-resistant layer 23 is provided on the inner wall of the clearance holes. The upper surface of the molding seat 7 has molding grooves 8 corresponding to each pressure plate 21.

[0020] A lifting cylinder 12 is provided below the molding base 7. A push plate 11 is fixed to the upper end of the cylinder rod of the lifting cylinder 12. A top material plate 9 is embedded in the bottom surface of the molding groove 8. A top material rod 10 passing through the bottom surface of the molding base 7 is provided on the bottom surface of the top material plate 9. The lower end of each top material rod 10 is connected and fixed to the push plate 11.

[0021] Working principle:

[0022] When in use, add the compounded brick material to each forming groove 8.

[0023] The lifting assembly is driven downward by hydraulic equipment. When the pressure plate 21 comes into contact with the raw material, the air injection equipment is activated, and compressed air is introduced into the air chamber 16 of the filter support plate 13 at a set frequency. This overcomes the tension of the return spring 19 and pushes the linkage plate 22 in each hollow pressure block 18 downward. The pressure plate 21 moves downward with the linkage plate 22. After the thrust of the compressed air is lost, the return spring 19 drives the linkage plate 22 and the pressure plate 21 to move upward and reset. This up-and-down reciprocating motion generates a vibratory and tamping effect on the raw material, which is beneficial for compacting the raw material and for forming high-density magnesium-iron-aluminum spinel sand bricks. After forming is completed, the lifting cylinder 12 is used to push the push plate 11, each top material rod 10, and the top material plate 9 upward, pushing the brick out of the forming groove 8 to achieve unloading.

[0024] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
