Description

Technical Field

[0001] This invention belongs to the field of brick technology, and in particular relates to a device for preparing environmentally friendly bricks from lithium slag. Background Technology

[0002] Lithium slag originates from the lithium salt production process and is classified into acidic and alkaline slags. Acidic lithium slag is the waste residue generated during the sulfuric acid process for lithium carbonate production. It is produced after lithium concentrate undergoes high-temperature roasting at 1300℃, acid roasting, atmospheric pressure water leaching, and liquid-solid separation. Guo Yuhua's production experiments have proven that acidic lithium slag is an active mixed material with extremely low alkali content. Utilizing lithium slag to produce cement bricks not only achieves the goal of comprehensively utilizing industrial waste and turning waste into resources, but also increases cement brick production, reduces production costs, improves cement brick performance, adjusts cement brick grades, and improves cement brick safety; it can also manufacture high-strength cement brick piles. Hu Biao et al.'s research on cement-based non-fired bricks showed that the optimal ratio of cement-based binder material was 80% cement brick material, 10% fly ash, and 10% slag powder. Increasing the amount of cement-based binder material significantly improved the strength, water resistance, and frost resistance of lithium slag non-fired bricks.

[0003] In the production process of non-fired cement bricks, molding equipment is used when forming the mold. Currently, the molds for producing square cement bricks are generally fixed-size molds, and different molds are required for bricks of different sizes. It is difficult to achieve that the same mold can adapt to the production of square bricks of different sizes at the same time. Even if the adjustable molds mentioned above exist, automating the production of adjustable molds is also a major challenge.

[0004] In addition, the molding process generally uses an upper mold pressing down on a lower mold. After molding, the lower mold flips over to pour out the brick. This demolding method increases the complexity of the mold's movement and the external driving structure. At the same time, the flipping action reduces the efficiency of brick making to some extent. Moreover, there is a risk of cracking the brick during the flipping process.

[0005] This invention designs an apparatus for preparing environmentally friendly bricks from lithium slag to solve the above problems. Summary of the Invention

[0019] 1. In this invention, the first, second, third, and fourth forming plates are all composed of two parts: an upper plate and a lower plate that are slidably connected.

Then, the pushing module is controlled to push the bricks on the mounting platform to the conveying module for transport. Compared with traditional equipment, the production equipment of this invention changes the demolding method of the bricks. This demolding method eliminates the operation of flipping the lower mold, improving production efficiency. At the same time, eliminating the flipping action simplifies the equipment structure and reduces equipment costs. In addition, the formed bricks are transferred to the mounting platform supported by the lower mold, thus avoiding collisions between the bricks and the mounting platform during flipping, which protects the formed bricks to a certain extent.

[0036] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following embodiments and drawings are used to illustrate the present invention, but are not intended to limit the scope of the invention.

[0037] A device for preparing environmentally friendly bricks from lithium slag, such as Figure 1 As shown, it includes a forming module 1 and a conveying module 2.

[0038] like Figure 2 , 3 As shown in Figures 5 and 7, the molding module 1 includes a first hydraulic rod 3, an upper mold 4, a lower mold 5, a mounting platform 6, a support rod 7, a first fixing rod 8, a U-shaped fixing rod 9, a second hydraulic rod 10, a slide rail 12, a switch-controlled slider 13, an adjustable molding mold 19, a pushing module 20, and a third hydraulic rod 28, wherein... Figure 6 As shown, a square inner groove 21 is formed on the upper surface of the mounting platform 6 near the conveying module 2. Two symmetrically distributed square sliding holes 22, penetrating the mounting platform 6 in the vertical direction, are formed on the bottom surface of the inner groove 21. The mounting platform 6 is fixedly installed on the foundation by four support rods 7. Figure 5 , 7As shown, two connecting rods 25 are slidably installed in two square sliding holes 22; the lower mold 5 is fixedly installed on the upper end of the two connecting rods 25 and located on the upper side of the mounting platform 6, and the lower mold 5 is aligned with the square inner groove 21 on the mounting platform 6; the first rack 26 is fixedly installed on the lower end of the two connecting rods 25 and located on the lower side of the mounting platform 6, the first gear 29 and the second gear 30 are coaxially rotatably installed on the lower side of the mounting platform 6, and the first gear 29 meshes with the first rack 26; the second rack 27 has an L-shaped structure, the second rack 27 is slidably installed on the lower side of the mounting platform 6, and the second rack 27 meshes with the second gear 30; the radius of the first gear 29 is twice the radius of the second gear 30; the third hydraulic rod 28 is fixedly installed on the lower side of the mounting platform 6, and the output end of the third hydraulic rod 28 is fixedly connected to the second rack 27; as shown Figure 2 , 3 As shown, four slide rails 12 are symmetrically fixedly installed on the upper side of the mounting platform 6 and located on the side of the mounting platform 6 with the inner groove 21; as Figure 3 , 4 As shown, the upper mold 4 is a square body. A square-shaped guide groove 15 running vertically through the center of the upper mold 4 is provided. An annular material groove 17 is provided on the inner side of the upper end of the upper mold 4. The upper end of the annular material groove 17 has a feed inlet 14, and the lower end of the annular material groove 17 has four circumferentially evenly distributed feed channels 16. The lower ends of the feed channels 16 communicate with the central guide groove 15. Four guide sliders 18 are fixedly installed on the outer side of the upper mold 4, such as... Figure 4 As shown, the upper mold 4 is mounted on the upper side of the mounting platform 6 through the sliding engagement of four guide sliders 18 and four slide rails 12; a U-shaped fixing rod 9 is fixedly mounted on the upper side of the upper mold 4, and a second hydraulic rod 10 is fixedly mounted on the inner end face of the U-shaped fixing rod 9. A switch control slider 13 is fixedly mounted on the output end of the second hydraulic rod 10. The switch control slider 13 is a square block, and the lower end of the switch control slider 13 has a stamp. The lower end of the switch control slider 13 is inserted into the guide groove 15 of the upper mold 4 and slides tightly with the guide groove 15; when not in operation, the lower end of the switch control slider 13 is located above the discharge port at the lower end of the four feed channels 16; the first hydraulic rod 3 is fixedly mounted on the upper side of the mounting platform 6 through the first fixing rod 8, and the output end of the first hydraulic rod 3 is fixedly connected to the upper end of the U-shaped fixing rod 9; as Figure 5 As shown, an adjustable molding mold 19 and a pushing module 20 are installed on the upper side of the mounting platform 6. The adjustable molding mold 19 is located between the upper mold 4 and the lower mold 5.

[0039] In this invention, the lower mold 5 is aligned with the square inner groove 21 on the mounting platform 6. After the lower mold 5 moves down, it can fit perfectly into the inner groove 21. After the lower mold 5 is placed in the inner groove 21, the upper end face of the lower mold 5 is flush with the upper surface of the mounting platform 6. This design can prevent the lower mold 5 from affecting the movement of the push plate 23 in the push module 20 when the formed brick is pushed onto the conveying module 2.

[0040] During production, in order to produce bricks of greater thickness to meet construction requirements, a large initial gap is needed between the lower end of the adjustable forming mold 19 and the mounting platform 6. This ensures that the thick bricks can be smoothly pushed onto the conveying module 2, without the upper end of the brick being embedded in the adjustable forming mold 19 and affecting the pushing of the bricks if the gap between the lower end of the adjustable forming mold 19 and the mounting platform 6 is smaller than the thickness of the brick. However, when the gap between the lower end of the adjustable forming mold 19 and the mounting platform 6 increases, the downward movement of the lower mold 5 also increases accordingly. Consequently, the extension and retraction of the third hydraulic rod 28 that drives the lower mold 5 also needs to increase accordingly. This means that the third hydraulic rod 28 requires a large space during installation, affecting the arrangement of other structures. At the same time, the stability is poor when the extension and retraction of the third hydraulic rod 28 is large. To solve this problem, the present invention provides a first gear 29 and a second gear 30 between the third hydraulic rod 28 and the lower mold 5, with the radius of the first gear 29 being twice the radius of the second gear 30. By increasing the transmission ratio, the third hydraulic rod 28 can move all the molded bricks out of the adjustable molding mold 19 with a shorter extension and retraction range, thus meeting production requirements while reducing the installation space required for the third hydraulic rod 28 during installation.

[0041] When the amount of cement brick material poured in during the single molding process completely fills the molding groove and meets the requirements for brick molding, the control switch controls the slider 13 to move down and close the four feeding channels. The amount of cement brick material required here is the amount of cement brick material poured in to ensure sufficient pressure between the cement brick material and the upper mold 4. Because the viscosity of the cement brick material used to produce bricks is relatively high, at this viscosity, it is ensured that the pressure formed between the cement brick material and the lower mold 5 by the amount of cement brick material poured in is sufficient to mold the cement brick material into bricks and meet the brick size requirements.

[0042] In this invention, the lower end of the switch control slider 13 has a stamp, which can be used to identify the produced bricks.

[0043] In this invention, after the cement brick material is pressed and formed, the lower mold 5 is controlled to move downward. The lower mold 5 drives the formed brick to move downward, so that the brick moves to the upper side of the mounting platform 6. Then, it is pushed by the pushing module 20 to the transportation module and transported away. After that, the lower mold 5 is controlled to move upward and fit tightly against the lower end of the adjustable forming mold 19. The second hydraulic rod 10 is controlled to work, so that the switch control slider 13 moves upward and opens the lower end of the four feeding channels. The cement brick material in the annular material groove 17 enters the adjustable forming mold 19 through the four feeding channels to form the next brick.

[0044] like Figure 8 , 9As shown in Figures 10 and 11, the adjustable molding die 19 includes a spring 31, a first molding plate 32, a fifth hydraulic rod 33, a second fixing rod 34, a second molding plate 35, a third fixing rod 36, a first guide slide rod 37, a sixth hydraulic rod 38, a third molding plate 39, a fourth molding plate 40, a fourth fixing rod 41, a guide plate 42, a second guide slide rod 43, and a drive slide bar 44. The first molding plate 32, the second molding plate 35, the third molding plate 39, and the fourth molding plate 40 are combined to form a square shape. Each of the first molding plate 32, the second molding plate 35, the third molding plate 39, and the fourth molding plate 40 consists of an upper plate 45 and a lower plate. Figure 13 , 14 As shown, the outer wall of the upper plate 45 has evenly distributed second trapezoidal grooves 48, and the inner wall of the lower plate has evenly distributed second trapezoidal sliders 52 fixedly installed; the upper plate 45 is installed on the upper side of the lower plate through the sliding cooperation of the second trapezoidal grooves 48 and the second trapezoidal sliders 52, as shown. Figure 10 , 11 As shown, evenly distributed springs 31 are installed between the upper plate 45 and the lower plate; Figure 13 As shown, the inner wall of the upper end of the upper plate 45 has horizontally distributed first trapezoidal grooves 46, and a first trapezoidal slider 47 is fixedly installed on one side of the upper end of the upper plate 45. The four upper plates 45 are interconnected through the sliding engagement of the first trapezoidal grooves 46 and the first trapezoidal slider 47; Figure 13 As shown, the lower plate of the third forming plate 39 is fixedly mounted on the upper side of the mounting platform 6 by multiple evenly distributed fourth fixing rods 41. A guide plate 42 is fixedly mounted on the lower plate of the third forming plate 39, and multiple second guide slide rods 43 are slidably mounted on the guide plate 42. The lower plate of the first forming plate 32 is fixedly mounted on the second guide slide rods 43 and is located on the upper side of the lower mold 5. Figure 14 As shown, a third trapezoidal slider 51 is fixedly installed on one side of the lower plate of the first forming plate 32; a third trapezoidal groove 50 is opened on the inner wall of the lower end of the lower plate of the second forming plate 35, and the lower plate of the second forming plate 35 is installed on the upper side of the lower mold 5 through the sliding cooperation of the third trapezoidal groove 50 on it and the third trapezoidal slider 51 on the lower plate of the first forming plate 32; Figure 8 , 11 As shown, a drive slide bar 44 is fixedly installed on the outer wall surface of the lower plate of the second forming plate 35, and the fifth hydraulic rod 33 is fixedly installed on the upper side of the mounting platform 6, as shown. Figure 12 As shown, the output end of the fifth hydraulic rod 33 is slidably connected to the drive slide bar 44 via the I-shaped connector 11; Figure 14 As shown, a third trapezoidal slider 51 is fixedly installed on one side of the lower plate of the second forming plate 35; as Figure 9As shown, the third fixing rod 36 is fixedly installed on the upper side of the mounting platform 6, and multiple first guide slide rods 37 are slidably installed on the third fixing rod 36. The lower plate of the fourth forming plate 40 is fixedly installed on the first guide slide rods 37 and located on the upper side of the lower mold 5; the sixth hydraulic rod 38 is fixedly installed on the third fixing rod 36, and the output end of the sixth hydraulic rod 38 is fixedly connected to the lower plate of the fourth forming plate 40; as shown Figure 14 As shown, a third trapezoidal groove 50 is formed on the inner wall of the lower end of the fourth forming plate 40, and the third trapezoidal groove 50 at the lower end of the fourth forming plate 40 slides in cooperation with the third trapezoidal slider 51 installed on the second forming plate 35.

[0045] In this invention, the first forming plate 32, the second forming plate 35, the third forming plate 39, and the fourth forming plate 40 are all composed of an upper plate 45 and a lower plate that are slidably connected. That is, the U-shaped template composed of the first forming plate 32, the second forming plate 35, the third forming plate 39, and the fourth forming plate 40 can extend and retract vertically. By controlling the extension and retraction of the U-shaped template, forming grooves of different thicknesses can be formed, thereby adapting to the thickness requirements of different types of bricks. The spring 31 serves to reset the extending and retracting U-shaped template.

[0046] The U-shaped template designed in this invention can adjust the cross-sectional size of the forming groove, making it suitable for different types of bricks with varying cross-sectional size requirements. During adjustment, the sixth hydraulic rod 38 is controlled to operate, pushing the fourth forming plate 40 to slide relative to the third forming plate 39. During this sliding, the upper plate 45 of the fourth forming plate 40 slides relative to the upper plate 45 of the third forming plate 39 under the cooperation of the corresponding first trapezoidal groove 46 and first trapezoidal slider 47. The lower plate of the fourth forming plate 40 slides relative to the lower plate of the third forming plate 39 under the action of the first guide rod. Although there is no direct connection between the lower plates of the fourth forming plate 40 and the lower plate of the third forming plate 39, the lower plate of the third forming plate 39 is fixed to the mounting platform 6 by the fourth fixing rod 41. The plate is slidably mounted on the mounting platform 6 under the guidance of the first guide rod and the third fixing rod 36. When the lower plate of the fourth forming plate 40 slides, it is always perpendicular to the lower plate of the third forming plate 39, and one end face of the lower plate of the fourth forming plate 40 is tightly against the inner wall of the third forming plate 39. Therefore, the motion relationship between the lower plate of the fourth forming plate 40 and the lower plate of the third forming plate 39 is fixed, and they will not separate even if there is no connecting structure between them. During the process of controlling the sixth hydraulic rod 38 to drive the fourth forming plate 40 to slide relative to the third forming plate 39, the lower plate of the fourth forming plate 40 and the lower plate of the second forming plate 35 are connected by a corresponding third ladder. The sliding connection between the trapezoidal groove 50 and the third trapezoidal slider 51 allows the lower plate of the fourth forming plate 40 to move relative to the third forming plate 39, thus pushing the lower plate of the second forming plate 35 to move together. The movement of the lower plate of the second forming plate 35 also drives the upper plate 45 of the second forming plate 35 to move. However, because the lower plate of the first forming plate 32 is slidably mounted on one side of the third forming plate 39 via the guide plate 42 and the second guide rod, the first forming plate 32 can only slide along the direction of the second guide rod, i.e., it can only slide in a direction perpendicular to the third forming plate 39. Furthermore, the second forming plate 35 is perpendicular to the first forming plate 32. Therefore, when the second forming plate... When the lower plate of the second forming plate 35 moves relative to the third forming plate 39, the lower plate of the second forming plate 35 also moves relative to the lower plate of the first forming plate 32 under the cooperation of the corresponding third trapezoidal slide groove 50 and the third trapezoidal slider 51. During this process, the distance between the fourth forming plate 40 and the first forming plate 32 becomes smaller. Moreover, during this process, because the fifth hydraulic rod 33 is slidably connected to the drive slide bar 44 installed on the lower plate of the second forming plate 35 through the I-shaped connector 11, even if the second forming plate 35 is driven by the fourth forming plate 40 to slide relative to the third forming plate 39, i.e., the mounting platform 6, it will not affect the connection between the fifth hydraulic rod 33 and the second forming plate 35.When the fifth hydraulic rod 33 is controlled to slide, it will drive the lower plate of the second forming plate 35 to slide via the drive slide bar 44. The lower plate of the second forming plate 35 moves relative to the lower plate of the fourth forming plate 40 under the cooperation of the corresponding third trapezoidal slider 51 and the third trapezoidal groove 50. The sliding of the lower plate of the second forming plate 35 drives the upper plate 45 to slide. Since the lower plate of the second forming plate 35 and the lower plate of the first forming plate 32 are slidably connected by the cooperation of the corresponding third trapezoidal groove 50 and the third trapezoidal slider 51, the movement of the lower plate of the second forming plate 35 will push the lower plate of the first forming plate 32 to move together relative to the fourth forming plate 40 and the third forming plate 39. When the lower plate of the first forming plate 32 moves, the upper plate 45 of the first forming plate 32 will move; during this process, the distance between the second forming plate 35 and the third forming plate 39 will decrease; that is, by controlling the fifth hydraulic rod 33 and the sixth hydraulic rod 38, the relative sliding between the first forming plate 32, the second forming plate 35, the third forming plate 39 and the fourth forming plate 40 can be controlled, and there will be no mutual interference during the sliding; by controlling the relative sliding between the first forming plate 32, the second forming plate 35, the third forming plate 39 and the fourth forming plate 40, the cross-sectional size of the forming groove can be adjusted to meet the cross-sectional size requirements of different types of bricks.

[0047] In this invention, a third trapezoidal groove 50 is formed on the lower plate of the fourth forming plate 40 and the lower plate of the second forming plate 35, and a third trapezoidal slider 51 is installed on the lower plate of the second forming template and the lower plate of the first forming template, instead of installing the third trapezoidal slider 51 on the lower plate of the fourth forming plate 40 and the lower plate of the second forming plate 35 and forming a third trapezoidal groove 50 on the lower plate of the second forming template and the lower plate of the first forming template. The reason for this design is to prevent the brick from being affected by the protruding third trapezoidal slider 51 on the lower plate of the fourth forming plate 40 and the lower plate of the second forming plate 35 after the brick is formed, thus preventing the brick from being removed from the adjustable forming mold 19. Similarly, the first trapezoidal slider 47 and the first trapezoidal groove 46 on the first forming plate 32, the second forming plate 35, the third forming plate 39 and the upper plate 45 of the fourth forming plate 40 are also designed to prevent the protruding first trapezoidal slider 47 from affecting the demolding of the brick.

[0048] like Figure 6 As shown, the pushing module 20 includes a push plate 23 and four hydraulic rods 24. Two symmetrically distributed four hydraulic rods 24 are fixedly installed on the upper side of the mounting platform 6, and the push plate 23 is fixedly installed on the output ends of the two four hydraulic rods 24. The sliding direction of the push plate 23 is perpendicular to the conveying direction of the conveying module 2. The operation of the four hydraulic rods 24 can drive the push plate 23 to move, pushing the formed bricks on the lower mold 5 onto the conveying module 2. The conveying module 2 of this invention uses a conveyor belt, which is existing technology.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0050] Implementation Method: When using the equipment designed in this invention, during production, firstly, the cross-sectional size of the middle forming groove of the adjustable forming mold 19 is adjusted according to the brick requirements of the building, i.e., the cross-sectional size of the formed brick. Then, the first hydraulic rod 3 is controlled to work, driving the U-shaped fixing rod 9 to move downwards. The U-shaped fixing rod 9 drives the upper mold 4 to move downwards. When the lower end face of the upper mold 4 contacts the upper end of the adjustable forming mold 19, the upper mold 4 continues to move downwards according to the brick thickness required for the building, so that the height of the adjustable forming mold 19 after compression meets the thickness of the cement brick material required for the brick. Then, the first hydraulic rod 3 is controlled to stop working, and the cement brick material is fed from the feed port 1 of the upper mold 4. The cement brick material is injected from four points, flowing along the annular material trough 17 and the four feeding channels 16 into the guide chute 15, and then from the guide chute 15 into the forming groove of the adjustable forming mold 19. When the amount of cement brick material injected is enough to completely fill the forming groove and meet the requirements for brick forming, the second hydraulic rod 10 is controlled to work. The second hydraulic rod 10 drives the switch to control the slider 13 to move down, sealing the lower ends of the four feeding channels 16. Finally, the switch controls the slider 13 to move to a state where its lower end face is flush with the lower end face of the upper mold 4. The switch control module and the upper mold 4 together apply pressure to the injected cement brick material. After the pressure reaches the required thickness of the brick, the forming is completed.

[0051] After the cement brick is pressed and formed, when the third hydraulic rod 28 is operated, the third hydraulic rod 28 will drive the second rack 27 to move. The movement of the second rack 27 will drive the second gear 30 to rotate. The rotation of the second gear 30 will drive the first gear 29 to rotate. The rotation of the first gear 29 will drive the first rack 26 to slide. The sliding of the first rack 26 will drive the lower mold 5 to move down through the two connecting rods 25. The lower mold 5 will drive the formed brick to move down, so that the brick moves to the upper side of the mounting platform 6. Then it will be pushed by the push module 20 to the transport module and transported away. Then the lower mold 5 will be controlled to move up and fit tightly against the lower end of the adjustable forming mold 19. The second hydraulic rod 10 will be controlled to operate, so that the switch control slider 13 will move up and open the lower end of the four feeding channels. The cement brick in the annular material trough 17 will enter the adjustable forming mold 19 through the four feeding channels to form the next brick.

[0052] After the bricks are formed, the excess edges and corners need to be cut off to make them fit the required bricks perfectly.

[0053] After several bricks have been formed, they can be washed with water.
