Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically to a raw material mixer and mixing process for manufacturing glass bricks. Background Technology

[0002] In the manufacturing process of glass bricks, the quality of raw material mixing directly affects the performance of the final product, such as strength, transparency, and flatness. Whether the raw materials are mixed evenly or not will lead to uneven distribution of components inside the glass brick, which in turn will cause quality defects such as bubbles, cracks, and color differences in the product. Therefore, efficient and uniform raw material mixing is a key link in the glass brick production process. Currently, most raw material mixing equipment used in glass brick manufacturing employs traditional mixers. These mixers typically involve pouring all required raw materials (such as quartz sand, soda ash, limestone, feldspar, etc.) into the mixing chamber at once, and then mixing them through the rotation of the mixing device. However, this method of mixing large quantities of raw materials at once has significant limitations. Firstly, due to the large volume of material, the material has a high density within the mixing chamber, requiring the mixing device to overcome significant material resistance to achieve mixing, thus significantly extending the mixing time and reducing overall production efficiency. This makes it difficult to meet the high-efficiency requirements of large-scale industrial production. Secondly, a large amount of material is prone to "agglomeration" during mixing, meaning some material is trapped inside and cannot fully contact or collide with other materials, greatly reducing the uniformity of mixing. This is especially true for raw materials with differences in density and particle size, where large-scale mixing at once is more likely to cause stratification, further exacerbating the poor mixing effect and seriously affecting the quality of subsequent glass brick production. Therefore, this paper proposes a raw material mixer and mixing process for glass brick manufacturing, which can achieve batch mixing of raw materials, improving mixing efficiency and effect. Summary of the Invention

[0008] Specifically, a drive motor for driving the drive shaft to rotate is installed at the top of the cylinder, and the lower end of the drive shaft is rotatably connected to the bottom of the cylinder.

[0009] Specifically, the lower part of the mixing cylinder is tapered, and a tapered cylinder is provided at the bottom of the inner side of the mixing cylinder. A sealing ring is fixedly connected to the upper surface of the tapered cylinder and is slidably connected to the inner wall of the mixing cylinder. A chamfer is provided on the upper part of the inner side of the sealing ring. The outer side of the elastic discharge pipe is provided with a fixing ring, and several sets of circumferentially distributed L-shaped connecting rods are fixedly connected to the outer side of the fixing ring. The upper end of the connecting rod passes through the mixing cylinder and is fixedly connected to the outer side of the conical cylinder. Several sets of circumferentially distributed support seats are fixedly connected to the outer side of the fixing ring. The support seats are connected to the mixing cylinder through compression springs. The outer side of the fixing ring is provided with a circumferentially distributed tooth structure. The lower end of the drive shaft is fixedly connected with a transmission gear. In the initial state, the transmission gear is staggered with the tooth structure.

[0010] Specifically, the telescopic assembly includes a chute disposed inside the first stirring rod, a second stirring rod being slidably connected to the chute, a return spring being fixedly connected between the second stirring rod and the inner wall of the chute, the elastic coefficient of several sets of return springs gradually increasing from bottom to top, and a vertically arranged liquid inlet channel being provided inside the second stirring shaft, the liquid inlet channel being connected to the chute, and the liquid inlet channel being filled with liquid; A liquid supply structure is provided between the first stirring shaft and the second stirring shaft, and the liquid supply structure is connected to the inside of the liquid inlet channel.

[0012] Specifically, a number of circumferentially distributed support rods are fixedly connected to the outer side of the cylinder, and an anti-slip base is fixedly connected to the lower end of the support rods.

[0013] A raw material mixing process for manufacturing glass bricks, employing the aforementioned raw material mixer for manufacturing glass bricks, specifically includes the following steps: S1. Mix the raw materials evenly according to the formula ratio required for glass brick manufacturing, and set aside. S2. Put the raw materials prepared in step S1 into the feeding funnel above the cylinder, drive the drive shaft to rotate, and drive the feeding plate and support ring to revolve around the drive shaft in a circle. When the feed inlets on the feed plate, which correspond one-to-one with the mixing cylinders, rotate to a position aligned with the lower end of the elastic feed tube, the raw material in the feed funnel, guided by the elastic feed tube, falls into the corresponding mixing cylinder directly below through this set of feed inlets. As the drive shaft continues to rotate the feed plate, this set of feed inlets is offset from the lower end of the elastic feed tube, and the elastic feed tube is sealed by being squeezed against the upper surface of the feed plate again, completing a single feeding of a single mixing cylinder. Subsequently, as the feed plate continues to rotate, each set of feed inlets on it aligns with the elastic feed tube in sequence, realizing batch-by-batch continuous feeding of multiple mixing cylinders. S3. During the feeding process in step S2, the support ring revolves synchronously, driving the drive structure on it to move together with the support ring. The drive structure starts and drives the stirring structure in the mixing cylinder to work. The stirring structure stirs and mixes the raw materials that have been fed into the mixing cylinder. S4. After the raw materials in the mixing drum have been stirred for the preset time in step S3, they are rotated to the designated discharge position with the support ring. The stirred raw materials are discharged from the mixing drum and enter the next production process. While one set of mixing drums is discharging, the other mixing drums are in the feeding or stirring stage respectively, completing the mixing operation of the raw materials for glass brick manufacturing.

[0014] The beneficial effects of this invention are: The present invention discloses a raw material mixer and mixing process for glass brick manufacturing. Through the cooperation of a circumferentially distributed mixing cylinder and a rotating feeding plate, the raw materials can be fed into different mixing cylinders in batches and simultaneously fed and stirred in a cycle. This avoids the material accumulation problem caused by traditional one-time large-scale feeding, reduces stirring resistance, shortens the mixing time of a single batch of raw materials, realizes continuous production, and meets the high-efficiency requirements of large-scale industrial production.

[0015] The present invention discloses a raw material mixer and mixing process for manufacturing glass bricks. While the mixing cylinder revolves around the support ring, the stirring structure rotates by meshing the drive gear and the internal gear ring, forming a compound motion of revolution and rotation. When the amount of material is large, the mixing cylinder can automatically start the rotation action, increasing the material turning frequency and shearing force, effectively solving the flow dead angle that is easily formed by traditional single stirring direction, reducing the stratification phenomenon of raw materials with different densities and particle sizes, avoiding agglomeration problems, and greatly improving the mixing uniformity.

[0016] The present invention discloses a raw material mixer and mixing process for glass brick manufacturing. The feed rate of a single mixing drum can be controlled by adjusting the speed of the drive shaft, which can adapt to the raw material requirements of different batches or formulas. The telescopic component of the stirring structure can dynamically adjust the extension length of the second stirring rod according to the material resistance, realizing a step-like extension from bottom to top and expanding the stirring range. At the same time, the adaptive self-rotation opening mechanism based on the material gravity can automatically switch the stirring intensity for different material amounts without manual intervention, improving the adaptability of the equipment to complex working conditions. The present invention discloses a raw material mixer and mixing process for manufacturing glass bricks. The elastic discharge pipe at the bottom of the mixing cylinder is automatically closed by compression with the bottom of the inner side of the cylinder. When the mixing cylinder rotates to the discharge pipe position, it automatically opens to discharge material. No additional valve control device is required, which simplifies the equipment structure and reduces energy consumption. It realizes continuous cycle of feeding, mixing and discharging, breaking through the limitations of the traditional intermittent production mode. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] In order to achieve batch mixing of raw materials, improve mixing efficiency and mixing effect, as an embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the present invention discloses a raw material mixer and mixing process for manufacturing glass bricks, comprising a cylinder 1, a feeding funnel 2 at the top of the cylinder 1, several sets of upward-opening and circumferentially distributed mixing cylinders 3 inside the cylinder 1, a support ring 4 rotatably connected to the outer side of the mixing cylinder 3, a vertically arranged drive shaft 5 inside the cylinder 1, the support ring 4 being fixedly connected to the drive shaft 5, a horizontally arranged feeding plate 6 fixedly connected to the drive shaft 5 on the inner side of the cylinder 1, an elastic feeding pipe 7 fixedly connected to the lower part of the feeding funnel 2, the lower end of the elastic feeding pipe 7 being in contact with the upper surface of the feeding plate 6, several sets of feeding ports 8 corresponding to the upper part of the mixing cylinder 3 on the feeding plate 6, a stirring structure inside the mixing cylinder 3, and a driving structure for driving the stirring structure on the support ring 4.

[0021] In use, the raw materials required for glass brick manufacturing are poured into the feeding funnel 2 according to the specified ratio. The equipment is then started to make the drive shaft 5 rotate. When the drive shaft 5 rotates, it synchronously drives the support ring 4 and the horizontal feed plate 6, which are fixedly connected to it, to move in a circular motion around the drive shaft 5. The support ring 4 rotates with the drive shaft 5, which in turn drives the outer mixing cylinder 3 to move in a circular motion along the inside of the cylinder 1. During the rotation of the feed plate 6 with the drive shaft 5, the upper surface of the feed plate 6 maintains a state of compression contact with the lower end of the elastic feed tube 7. When a set of feed inlets 8 on the feed plate 6 rotates to a position corresponding to the lower end of the elastic feed tube 7, the raw material in the feed funnel 2 is guided by the elastic feed tube 7 and falls into the corresponding mixing cylinder 3 directly below through the set of feed inlets 8. As the drive shaft 5 continues to rotate, the set of feed inlets 8 on the feed plate 6 is offset from the lower end of the elastic feed tube 7, and the elastic feed tube 7 is closed due to the squeezing contact with the surface of the feed plate 6, and the feeding process is paused. While the mixing cylinder 3 moves in a circular motion with the support ring 4, the drive structure on the support ring 4 works synchronously. The drive structure drives the stirring structure in the mixing cylinder 3 to start, and stirs and mixes the raw material that has entered the mixing cylinder 3. When a set of mixing cylinders 3 has completed feeding and continues to stir while rotating, the feed plate 6 continues to rotate, and the next set of feed inlets 8 on it is aligned with the lower end of the elastic feed tube 7 again as it rotates. At this time, the raw material enters the next mixing cylinder 3 through the set of feed inlets 8, realizing batch continuous feeding. This design avoids the material accumulation problem caused by the large amount of raw materials fed at once in traditional equipment. The amount of material fed at one time is reduced because it is distributed among multiple mixing drums 3, which reduces the material resistance of the stirring structure and shortens the mixing time of a single set of raw materials. In addition, the multiple mixing drums 3 circulate and stir, which significantly improves the overall mixing efficiency and meets the needs of continuous industrial production. At the same time, the circumferential motion of the mixing drum 3 and the synchronous work of the stirring structure allow the raw materials to enter the stirring state immediately after feeding, reducing the static accumulation time of the raw materials in the drum and further improving the stability of the mixing effect.

[0022] To facilitate stirring and agitating the raw materials within mixing drum 3 and to complete the mixing of the materials, for example, such as... Figure 7 , Figure 9 As shown, the present invention also includes a stirring structure comprising a vertically arranged first stirring shaft 9, the upper end of the first stirring shaft 9 being rotatably connected to the feed plate 6, the lower end of the first stirring shaft 9 being connected to a second stirring shaft 10, the second stirring shaft 10 being provided with a plurality of circumferentially distributed first stirring rods 11, a first pulley 12 being fixedly connected to the first stirring shaft 9, the driving structure being used to drive the first pulley 12 to rotate, and the first stirring rod 11 being provided with a telescopic component.

[0023] In use, the drive shaft 5 drives several sets of mixing cylinders 3 to rotate. When the mixing cylinders 3 rotate, the drive structure drives the first pulley 12 to rotate. The first pulley 12 then drives the first stirring shaft 9 and the second stirring shaft 10 to rotate synchronously. When the second stirring shaft 10 rotates, the first stirring rod 11 stirs and turns the raw materials in the mixing cylinders 3 to complete the mixing of materials. At the same time, the telescopic component inside the first stirring rod 11 can further adjust the stirring range and intensity according to the amount of material in the mixing cylinders 3 during the stirring process, so as to achieve faster and more thorough stirring action, shorten the mixing time of a single set of raw materials, and improve the overall mixing efficiency.

[0024] To improve mixing uniformity, for example, such as Figure 3 , Figure 6 As shown, the present invention also includes a drive structure comprising a vertically arranged drive rod 13, the lower end of which is connected to a support ring 4 via a rotating seat 14, a drive gear 15 and a second pulley 16 coaxially connected to the drive rod 13, an internal gear ring 17 meshing with the drive gear 15 fixedly connected to the inner wall of the cylinder 1, and the second pulley 16 and the first pulley 12 being driven by a transmission belt 18.

[0025] In use, when the drive shaft 5 drives the support ring 4 to make a circular motion around the drive shaft 5, the support ring 4 drives the drive rod 13 to make a circular motion synchronously through the rotating seat 14. As the drive rod 13 rotates with the support ring 4, the drive gear 15 will mesh with the internal gear ring 17 to drive the drive rod 13 to rotate. The second pulley 16 rotates synchronously with the drive rod 13. The second pulley 16 transmits the rotational power to the first pulley 12 through the transmission belt 18. The first pulley 12 drives the first stirring shaft 9 and the second stirring shaft 10 and the first stirring rod 11 below to rotate, thereby realizing the stirring action of the raw materials in the mixing drum 3. By converting the circular motion of the support ring 4 into the rotational power of the stirring structure, the stirring action can be driven without an additional independent power source, realizing the utilization of the equipment power, simplifying the equipment structure and reducing energy consumption. Relying on the driving structure and the support ring 4, the mixing cylinder 3 moves in a circular motion with the support ring 4. At the same time, the stirring structure obtains rotational power synchronously through the driving structure, forming a compound motion of the circular revolution of the mixing cylinder 3 and the rotation of the stirring rod. The spatial displacement driven by the centrifugal force generated by the rotation of the mixing cylinder 3 makes the material movement path more complex and covers a wider range. This significantly increases the movement path and collision frequency of the raw materials in the mixing cylinder 3, solving the dead angle of material flow that is easily formed by traditional single stirring direction. Especially for raw materials with differences in density and particle size, it can reduce the stratification phenomenon caused by gravity and improve the mixing uniformity.

[0026] To facilitate the discharge of the mixed material and achieve a continuous cycle from feeding to mixing and discharging, for example, such as... Figure 4 , Figure 7 , Figure 8 As shown, the present invention also includes an elastic discharge pipe 19 installed at the bottom of the mixing cylinder 3, the elastic discharge pipe 19 being in contact with the bottom inner side of the cylinder body 1, and a discharge pipe 20 being provided at the bottom of the cylinder body 1.

[0027] When in use, as the mixing cylinder 3 rotates around the drive shaft 5 with the support ring 4, the elastic discharge pipe 19 always maintains a squeezing contact with the bottom of the inner side of the cylinder 1. During the raw material mixing stage, the elastic discharge pipe 19 is in a closed state due to the squeezing of the bottom of the cylinder 1, ensuring that the raw materials in the mixing cylinder 3 are fully mixed under the action of the mixing structure, and avoiding premature leakage of unmixed raw materials. When the mixing drum 3 completes the preset mixing time and rotates to a specific area at the bottom of the drum 1 with the support ring 4, the elastic discharge pipe 19 at the bottom of the mixing drum 3 and the discharge pipe 20 at the bottom of the drum 1 gradually align and connect. Subsequently, the fully mixed raw materials in the mixing drum 3 are discharged in sequence through the elastic discharge pipe 19 and the discharge pipe 20 and transported to the subsequent production process. The automatic opening and closing of the discharge is achieved by the circular motion of the mixing drum 3 and the elastic characteristics of the elastic discharge pipe 19, without the need for additional complex valve control devices. At the same time, when one set of mixing drums 3 finishes mixing and discharges raw materials through the discharge pipe 20, other mixing drums 3 are still in the feeding or mixing process, realizing a continuous cycle from feeding to mixing and discharging, solving the intermittent production mode of traditional equipment that discharges material after one mixing, and significantly improving the overall production efficiency.

[0028] For example, such as Figure 1 As shown, the present invention also includes a drive motor 21 for driving the drive shaft 5 to rotate, which is installed on the top of the cylinder 1, and the lower end of the drive shaft 5 is rotatably connected to the bottom of the cylinder 1.

[0029] When in use, when it is necessary to mix the raw materials, start the drive motor 21 installed on the top of the cylinder 1. The drive motor 21 outputs power to drive the drive shaft 5 connected to it to start rotating, which facilitates the synchronous rotation of the support ring 4, the mixing cylinder 3 and the feed plate 6. The batch feeding and mixing is completed by relying on the rotation of the mixing cylinder 3 and the feed plate 6.

[0030] To increase the tumbling frequency and shearing force of the material within the mixing drum 3, for example, such as Figure 5 , Figure 7 , Figure 8 As shown, the present invention also includes a lower part of the mixing cylinder 3 being tapered, a tapered cylinder 22 being provided at the bottom of the inner side of the mixing cylinder 3, and a sealing ring 23 being fixedly connected to the upper surface of the tapered cylinder 22 and slidably connected to the inner wall of the mixing cylinder 3, and a chamfer 24 being provided on the upper inner side of the sealing ring 23; The outer side of the elastic discharge pipe 19 is provided with a fixing ring 25. Several sets of circumferentially distributed L-shaped connecting rods 26 are fixedly connected to the outer side of the fixing ring 25. The upper end of the connecting rod 26 passes through the mixing cylinder 3 and is fixedly connected to the outer side of the conical cylinder 22. Several sets of circumferentially distributed support seats 27 are fixedly connected to the outer side of the fixing ring 25. The support seats 27 are connected to the mixing cylinder 3 through compression springs 28. The outer side of the fixing ring 25 is provided with circumferentially distributed toothed structures 29. The lower end of the drive shaft 5 is fixedly connected with a transmission gear 30. In the initial state, the transmission gear 30 is staggered with the toothed structures 29.

[0031] When in use, after starting the drive motor 21 at the top of the cylinder 1, the speed of the drive shaft 5 can be adjusted according to the processing requirements of the materials to be mixed, such as the amount of material to be mixed at one time and the mixing accuracy. The speed of the drive shaft 5 directly affects the rotation speed of the horizontal feed plate 6. When the speed of the drive shaft 5 is faster, the overlap time between the feed port 8 on the feed plate 6 and the lower end of the elastic feed pipe 7 is shortened, and the amount of material flowing into the mixing cylinder 3 per unit time is reduced. When the speed of the drive shaft 5 is slower, the overlap time between the feed port 8 and the elastic feed pipe 7 is extended, and the amount of material entering the mixing cylinder 3 is increased accordingly, thereby achieving precise control of the amount of material and adapting to the mixing requirements of different batches or different formulas of raw materials. When a large amount of material enters the mixing cylinder 3, the material's own gravity will exert a downward squeezing force on the conical cylinder 22 at the bottom of the inner side of the mixing cylinder 3. Under the action of gravity, the conical cylinder 22 slides down along the inner wall of the mixing cylinder 3. The sealing ring 23 fixed on its outer side maintains a sealed sliding connection with the inner wall of the mixing cylinder 3 to prevent material leakage from the gap. At the same time, the chamfered structure 24 on the upper inner side of the sealing ring 23 can guide the material to flow towards the edge of the conical cylinder 22, preventing the material from accumulating on the upper surface of the conical cylinder 22 and forming dead corners. When the conical cylinder 22 moves downward, the connecting rod 26 synchronously drives the fixed ring 25 to move downward. During the downward movement of the fixed ring 25, the compression spring 28 is stretched and stores force. As the fixed ring 25 continues to move downward, the tooth structure 29 distributed on its outer circumference gradually aligns with and meshes with the transmission gear 30 at the lower end of the drive shaft 5. At this time, the drive shaft 5 rotates and drives the transmission gear 30 to rotate. Through gear meshing, the fixed ring 25 is driven to rotate. The fixed ring 25 then drives the conical cylinder 22 and the mixing cylinder 3 to rotate synchronously through the connecting rod 26. The mixing cylinder 3, based on the original revolution with the support ring 4, adds its own rotation action to achieve enhanced mixing of a large amount of material. This increases the tumbling frequency and shearing force of the material in the mixing cylinder 3, effectively solving the problem of insufficient mixing and easy agglomeration caused by the accumulation of a large amount of material in traditional equipment, improving the mixing uniformity. At the same time, it can be automatically opened according to the amount of material in the mixing cylinder 3 without additional manual intervention, improving the automation and stability of the equipment operation. After mixing is complete, the material discharge reduces the gravity on the conical cylinder 22, the compression spring 28 resets and drives the fixed ring 25 to move upward, the tooth structure 29 disengages from the transmission gear 30, and the mixing cylinder 3 returns to the state of only revolving with the support ring 4.

[0032] To increase the mixing radius, reduce stratification and dead zones, and improve mixing uniformity, for example, such as Figure 9 , Figure 10 , Figure 11 As shown, the present invention also includes the following: the telescopic component includes a groove 31 disposed inside the first stirring rod 11; a second stirring rod 32 is slidably connected to the groove 31; a return spring 33 is fixedly connected between the second stirring rod 32 and the inner wall of the groove 31; the elastic coefficient of several sets of return springs 33 gradually increases from bottom to top; a vertically arranged liquid inlet channel 34 is provided inside the second stirring shaft 10; the liquid inlet channel 34 communicates with the groove 31; and the liquid inlet channel 34 is filled with liquid. A liquid supply structure is provided between the first stirring shaft 9 and the second stirring shaft 10, and the liquid supply structure is internally connected to the liquid inlet channel 34.

[0033] When in use, when there is a large amount of material in the mixing drum 3, the material resistance encountered by the first stirring rod 11 increases. At this time, the liquid supply structure is activated, pumping the liquid into the liquid inlet channel 34 inside the second stirring shaft 10. Under pressure, the liquid enters the slide groove 31, generating a thrust on the second stirring rod 32 with a sealed sliding connection. Under the action of liquid pressure, the second stirring rod 32 overcomes the elastic force of the return spring 33 and extends outward along the slide groove 31, expanding the stirring range. Since the elastic coefficient of several sets of return springs 33 gradually increases from bottom to top, the elastic coefficient of the lower return spring 33 is smaller. Under the same liquid pressure, the lower second stirring rod 32 extends outward before the upper one. As the liquid pressure continues to increase or the material resistance further increases, the upper return spring 33 with a larger elastic coefficient is gradually overcome, and the upper second stirring rod 32 extends outward accordingly, realizing the step-like extension of the second stirring rod 32 from bottom to top. When the amount of material in the mixing cylinder 3 decreases and the stirring resistance decreases, the liquid supply structure reduces the liquid supply, the return spring 33 releases its elastic force, and pushes the second stirring rod 32 to retract along the slide groove 31 to the initial position, completing the cycle of extension and retraction. This invention solves the problem of insufficient mixing or excessive energy consumption of traditional fixed-length stirring rods for different material quantities. Especially for raw materials with large differences in density and particle size, it can reduce stratification and dead corners by expanding the mixing radius, thereby improving the uniformity of mixing. At the same time, the sealed sliding connection between the second stirring rod 32 and the slide 31 reduces the risk of raw materials entering the gap. Combined with the reciprocating friction of the telescopic movement, it can reduce material residue and reduce the difficulty of subsequent equipment cleaning, thus solving the problem of cleaning dead corners caused by the fixed structure of traditional stirring rods.

[0034] To adapt to the mixing requirements under different material quantities, for example, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the present invention also includes a liquid supply structure comprising a mounting base 35 fixedly connected to the lower surface of the first stirring shaft 9, the mounting base 35 having a mounting groove 36 therein, the upper end of the second stirring shaft 10 passing through the mounting base 35 and rotatably connected to the mounting base 35, and a torsion spring 37 fixedly connected between the upper end of the second stirring shaft 10 and the inner wall of the mounting groove 36. The mounting base 35 is fixedly connected to the second stirring shaft 10 via an arc-shaped hydraulic telescopic rod 38. The side of the arc-shaped hydraulic telescopic rod 38 is connected to the liquid outlet connector 39, and the liquid outlet connector 39 is connected to the liquid inlet channel 34 via a pipeline.

[0035] When in use, the first stirring shaft 9 rotates under the drive structure, and the mounting base 35 rotates synchronously with the first stirring shaft 9. When the amount of material in the mixing drum 3 is large and the stirring resistance increases, the reaction force of the second stirring shaft 10 causes it to rotate relative to the mounting base 35. At this time, the torsion spring 37 is twisted and stored. At the same time, the arc-shaped hydraulic telescopic rod 38 between the mounting base 35 and the second stirring shaft 10 is squeezed due to the relative rotation of the two. The liquid inside the arc-shaped hydraulic telescopic rod 38 is transported to the liquid inlet channel 34 through the liquid outlet joint 39 on the side under pressure, providing liquid pressure to the sliding groove 31 of the telescopic component, thereby driving the second stirring rod 32 to extend and accurately adapt to the stirring needs under different material amounts. When the amount of material in the mixing drum 3 decreases and the stirring resistance decreases, the torsion spring 37 releases its stored force, driving the second stirring shaft 10 to rotate and reset. The arc-shaped hydraulic telescopic rod 38 then returns to its original state, and its internal pressure decreases. The liquid in the liquid inlet channel 34 flows back to the arc-shaped hydraulic telescopic rod 38 through the pipeline, completing the liquid circulation. During this process, the rotational connection between the mounting base 35 and the second stirring shaft 10 ensures the smoothness of the relative movement, while the torsion spring 37 provides elastic power for the structural reset, realizing the dynamic adjustment of the liquid supply. It can adapt to different material mixing scenarios without manual intervention.

[0036] For example, such as Figure 1 As shown, the present invention also includes a plurality of circumferentially distributed support rods 40 fixedly connected to the outer side of the cylinder 1, and an anti-slip base 41 fixedly connected to the lower end of the support rods 40.

[0037] During use, the support rod 40 and the anti-slip base 41 can evenly distribute the weight and operating load of the cylinder 1 and internal components, avoid excessive local stress, ensure the overall structural stability of the equipment, and improve the safety of equipment operation and production continuity.

[0038] A raw material mixing process for manufacturing glass bricks, employing the aforementioned raw material mixer for manufacturing glass bricks, specifically includes the following steps: S1. Mix the raw materials evenly according to the formula ratio required for glass brick manufacturing, and set aside. S2. Put the raw materials prepared in step S1 into the feeding funnel 2 above the cylinder 1, drive the drive shaft 5 to rotate, and drive the feeding plate 6 and support ring 4 to revolve around the drive shaft 5. When the feed inlets 8 on the feed plate 6, which are corresponding one-to-one with the mixing cylinders 3, rotate to a position aligned with the lower end of the elastic feed tube 7, the raw material in the feed funnel 2 is guided by the elastic feed tube 7 and falls into the corresponding mixing cylinder 3 directly below through the feed inlets 8. As the drive shaft 5 continues to drive the feed plate 6 to rotate, the feed inlets 8 are offset from the lower end of the elastic feed tube 7, and the elastic feed tube 7 is closed by being squeezed against the upper surface of the feed plate 6 again, completing a single feeding of a single mixing cylinder 3. Subsequently, as the feed plate 6 continues to rotate, each set of feed inlets 8 on it is aligned with the elastic feed tube 7 in sequence, realizing batch-by-batch continuous feeding of multiple mixing cylinders 3. S3. During the feeding process in step S2, the support ring 4 revolves synchronously, driving the drive structure on it to move together with the support ring 4. The drive structure starts and drives the stirring structure in the mixing cylinder 3 to work. The stirring structure stirs and mixes the raw materials that have been fed into the mixing cylinder 3. S4. After the raw material in the mixing cylinder 3 has been stirred for the preset time in step S3, it rotates with the support ring 4 to the designated discharge position. The stirred raw material is discharged from the mixing cylinder 3 and enters the next production process. While one set of mixing cylinders 3 is discharging, the other mixing cylinders 3 are in the feeding or stirring stage respectively, completing the mixing operation of the raw materials for glass brick manufacturing.

[0039] When using this invention, the drive motor 21 installed on the top of the cylinder 1 is started. The drive motor 21 outputs power to drive the vertical drive shaft 5 connected to it to start rotating. The support ring 4 and the horizontal feed plate 6 fixedly connected to the drive shaft 5 move in a circular motion around the drive shaft 5. At the same time, the support ring 4 drives the outer mixing cylinder 3 to rotate synchronously. During the rotation of the feed plate 6, its upper surface always maintains a squeezing contact with the lower end of the elastic feed tube 7. The prepared raw materials are poured into the feeding funnel 2 above the cylinder 1 at a uniform speed. When a set of feeding ports 8 on the feeding plate 6, which corresponds to the upper part of the mixing cylinder 3, rotates to the position corresponding to the lower end of the elastic feeding tube 7, the elastic feeding tube 7 is released from the squeezed and closed state. The raw materials in the feeding funnel 2 are guided through the elastic feeding tube 7 and fall into the mixing cylinder 3 directly below through the set of feeding ports 8. As the drive shaft 5 continues to drive the feeding plate 6 to rotate, the set of feeding ports 8 and the lower end of the elastic feeding tube 7 are misaligned. The elastic feeding tube 7 is closed again due to the squeeze against the surface of the feeding plate 6, and the feeding of the mixing cylinder 3 is suspended. The feed plate 6 continues to rotate, and the next set of feed inlets 8 align with the lower end of the elastic feed tube 7 again as it rotates, so that the raw material enters the next mixing cylinder 3, realizing continuous batch feeding of multiple sets of mixing cylinders 3; The support ring 4 drives the drive rod 13 to perform a synchronous circular motion. The drive gear 15 on the drive rod 13 meshes with the internal gear ring 17 fixed on the inner wall of the cylinder 1, causing the drive rod 13 to rotate. The second pulley 16, which is coaxially connected to the drive rod 13, rotates with it and transmits power to the first pulley 12 on the first stirring shaft 9 through the transmission belt 18. The first pulley 12 drives the first stirring shaft 9 to rotate. The second stirring shaft 10, which is connected to the lower end of the first stirring shaft 9, rotates synchronously. Several sets of circumferentially distributed first stirring rods 11 on the second stirring shaft 10 stir and agitate the raw materials in the mixing cylinder 3. The feeding amount can be controlled by adjusting the speed of the drive motor 21. If the speed is fast, the overlap time between the feed port 8 and the flexible feed tube 7 is shortened, and the feeding amount per batch is reduced; if the speed is slow, the overlap time is extended and the feeding amount is increased. When a large amount of material is fed into a mixing drum 3, the weight of the large amount of material in the mixing drum 3 exerts a downward squeezing force on the conical cylinder 22 at the bottom of the inner side. The conical cylinder 22 slides down along the inner wall of the mixing drum 3, and the outer sealing ring 23 slides in a sealing manner with the inner wall of the mixing drum 3 to prevent material leakage. The chamfer 24 on the upper inner side of the sealing ring 23 guides the material to flow towards the edge to prevent accumulation in dead corners. When the conical cylinder 22 moves downward, the connecting rod 26 drives the fixing ring 25 on the outside of the elastic discharge pipe 19 to move downward synchronously. The support seat 27 on the outside of the fixing ring 25 stretches and compresses the spring 28 to store force. When the tooth structure 29 on the outside of the fixing ring 25 moves downward to align with and mesh with the transmission gear 30 at the lower end of the drive shaft 5, the drive shaft 5 drives the transmission gear 30 to rotate. Through gear meshing, the fixing ring 25, connecting rod 26, conical cylinder 22 and mixing cylinder 3 rotate synchronously. The rotation is added on the basis of revolution, which enhances the material turning frequency and shearing force. When the amount of material in the mixing drum 3 decreases during the mixing process, or after subsequent discharge, the gravity on the conical drum 22 decreases, the compression spring 28 resets and drives the fixed ring 25 to move upward, the tooth structure 29 disengages from the transmission gear 30, and the mixing drum 3 returns to the state of only revolving. When there is a large amount of material in the mixing drum 3 and the stirring resistance is high, the second stirring shaft 10 rotates relative to the mounting base 35 under the first stirring shaft 9 under the reaction force, and twists the torsion spring 37 in the mounting groove 36; at the same time, the arc-shaped hydraulic telescopic rod 38 between the mounting base 35 and the second stirring shaft 10 is squeezed, and the internal liquid is transported to the vertical liquid inlet channel 34 in the second stirring shaft 10 through the liquid outlet joint 39 and the pipeline. The liquid in the inlet channel 34 enters the slide groove 31 of the first stirring rod 11, pushing the second stirring rod 32, which is connected in a sealed sliding connection, to overcome the elastic force of the return spring 33 and extend outward. Because the elastic coefficient of several sets of return springs 33 gradually increases from bottom to top, the lower part of the second stirring rod 32 extends out first, and the upper part extends out later as the pressure increases, thereby realizing a step-like expansion of the stirring range. When the amount of material decreases and the stirring resistance decreases, the torsion spring 37 resets and drives the second stirring shaft 10 to rotate. The arc-shaped hydraulic telescopic rod 38 returns to its original state, the liquid in the liquid inlet channel 34 flows back, and the reset spring 33 pushes the second stirring rod 32 to retract into the trough 31. After the raw materials in the mixing cylinder 3 have completed the preset mixing time, they rotate with the support ring 4 to the discharge area at the bottom of the cylinder 1. The elastic discharge pipe 19 at the bottom of the mixing cylinder 3 was previously kept closed due to the compression with the bottom of the inner side of the cylinder 1. When the mixing cylinder 3 rotates to above the discharge pipe 20, the elastic discharge pipe 19 and the discharge pipe 20 gradually align and connect, the compression state is released, and the uniformly mixed raw materials are discharged in sequence through the elastic discharge pipe 19 and the discharge pipe 20, and then transported to the subsequent glass brick production process. While one set of mixing drums 3 is discharging material, the other mixing drums 3 are still in the feeding or mixing stage, realizing continuous production of feeding, mixing and discharging, breaking through the limitations of traditional intermittent production.

[0040] like Figure 13 As shown, the processing technology of the glass bricks involved in this invention includes the following: Raw material mixing: All kinds of basic raw materials required for glass brick production are put into the raw material mixer according to the precise formula ratio and mixed thoroughly to lay the foundation for subsequent processing.

[0041] Conveying and storage: The mixed raw materials are conveyed to the kiln head silo for temporary storage via a batching conveyor belt. They are then precisely controlled by a single gate and a feeding machine and fed into the glass melting furnace according to the production rhythm.

[0042] High-temperature melting: Glass melting furnaces use natural gas (or heavy oil) as fuel and introduce combustion air to melt the input batch materials into molten glass in a high-temperature environment inside the furnace. The generated waste gas is treated by environmental protection and the boiler recovers heat before being discharged through the chimney in compliance with standards.

[0043] Material feeding and picking: The feeding machine (picking machine) obtains molten glass from the melting furnace. This step can be supplemented with natural gas to ensure temperature and material condition, in preparation for molding.

[0044] Pressing and molding: Molten glass enters the pressing machine and is pressed into the preliminary shape of glass bricks by the action of molds and other equipment.

[0045] Conveying and Welding: The formed glass brick blanks are transported by a conveyor, and the temperature is maintained at a suitable level with the assistance of natural gas. The splicing parts are welded by a welding machine to ensure the integrity of the structure.

[0046] Annealing treatment: The glass bricks are conveyed again to the annealing furnace to eliminate internal stress and improve product stability. Natural gas is still required to regulate the temperature environment during the conveying process.

[0047] Manual inspection: After annealing, the glass bricks are manually inspected to remove unqualified products; qualified products enter the painting process, where they are given their appearance, color, and other characteristics, and are then manually inspected again.

[0048] Finished product packaging: Glass bricks that pass the second inspection are packaged, stored in the warehouse, and finally shipped to the market according to order requirements.

[0049] Waste generated at each stage of processing is fed into a crusher for crushing. The crushed material can be transported back to the raw material mixing stage to participate in the batching again, realizing resource recycling and effectively reducing production costs and waste emissions.
