Description

Technical Field

[0001] This utility model relates to the field of refractory brick production technology, specifically to an auxiliary material addition and mixing device for refractory brick production. Background Technology

[0002] As a key basic material in industrial production, refractory bricks are widely used in high-temperature operating scenarios such as metallurgy, building materials, and chemical industry due to their excellent high-temperature resistance, structural stability, and abrasion resistance. The addition and mixing of auxiliary materials is one of the core links in the production of refractory bricks. The uniformity of the mixing of auxiliary materials directly affects the density, strength, and high-temperature resistance of refractory bricks, and plays a decisive role in the quality of the final product. With the continuous improvement of the performance requirements of refractory bricks in industrial production, the precision and efficiency of the auxiliary material mixing process have become the focus of industry attention. In the existing technology, the auxiliary material mixing device for refractory brick production mostly adopts a single stirring rod rotating stirring structure. Some devices are equipped with fixed auxiliary stirring blades. The working process usually involves putting various auxiliary materials into the mixing drum in proportion, driving the stirring rod to rotate around a fixed shaft by a motor, and using the rotation of the stirring rod to drive the auxiliary materials to flow in the drum to achieve mixing of different auxiliary materials. After mixing, the mixture is discharged to the next process through the discharge port. Existing mixing devices have certain limitations in practical applications: the mixing trajectory is relatively simple, mostly circular motion or multiple mixing rods rotating in opposite directions, which easily creates dead zones inside the mixing drum, resulting in some auxiliary materials not being able to fully contact each other; at the same time, the mixing components of traditional devices lack telescopic or multi-dimensional motion functions, and have limited adaptability to auxiliary materials of different particle sizes and densities, making it difficult to meet the mixing quality requirements of high-precision production. Therefore, we propose an auxiliary material addition and mixing device for refractory brick production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an auxiliary material addition and mixing device for refractory brick production. Through multi-dimensional stirring and diversion design, the mixing uniformity and uniform discharge are greatly improved, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary material addition and mixing device for refractory brick production, including an auxiliary material addition cylinder and a mixing mechanism; The mixing mechanism includes a mounting plate, a main mixing rod, a secondary mixing rod, a drive rod, and a passive rod. The mounting plate is rotatably connected to the upper inner end of the auxiliary additive cylinder. The main mixing rod is rotatably connected to the middle of the mounting plate. The secondary mixing rods are slidably connected to the mounting holes at the left and right ends of the mounting plate. The drive rod is fixedly connected to the lower outer arc surface of the main mixing rod. A first inclined surface is provided on the upper rear end of the drive rod. The passive rods are all fixedly connected to the lower outer arc surface of the secondary mixing rods. A second inclined surface is provided on the lower side of each passive rod. The second inclined surface cooperates with the first inclined surface. Through multi-dimensional stirring and diversion design, the mixing uniformity and uniform discharge are greatly improved.

[0005] Furthermore, the outer arc surface of the auxiliary adding cylinder is provided with a control switch group, the input end of which is electrically connected to an external power supply for stable control.

[0006] Furthermore, the mixing mechanism also includes a driven gear and an internal gear ring. The driven gear is rotatably connected to the top wall of the auxiliary adding cylinder via a rotating shaft, and the internal gear ring is fixedly connected to the upper side of the mounting plate and meshes with the driven gear to drive the mounting plate to rotate.

[0007] Furthermore, the mixing mechanism also includes a gear, which is fixedly connected to the upper outer arc surface of the main mixing rod and meshes with the driven gear. The meshing of the gear and the driven gear causes the internal gear ring to rotate in the opposite direction to the gear.

[0008] Furthermore, the mixing mechanism also includes a motor, which is mounted on the upper side of the auxiliary adding cylinder. The output shaft of the motor is fixedly connected to the center of the upper end face of the main mixing rod, and the input end of the motor is electrically connected to the output end of the control switch group for stable driving.

[0009] Furthermore, a stainless steel mesh frame is installed at the lower end of the auxiliary feeding cylinder, and evenly distributed conical protrusions are fixedly connected to the upper side of the stainless steel mesh frame for diversion.

[0010] Furthermore, a gate valve is connected in series at the lower end of the auxiliary additive cylinder. The input end of the gate valve is electrically connected to the output end of the control switch group to open and close the discharge channel of the auxiliary additive cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This auxiliary material addition and mixing device for refractory brick production has the following advantages: The mixing mechanism is driven by a motor to rotate the main mixing rod. The meshing transmission of gears, driven gears and internal gear ring drives the mounting plate to move in the opposite direction in a circular motion. At the same time, the inclined surfaces of the drive rod and the driven rod make the auxiliary mixing rod reciprocate up and down, forming a multi-dimensional and all-area covering mixing trajectory. This effectively eliminates mixing dead corners, avoids local accumulation of auxiliary materials, and greatly improves the uniformity of mixing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This embodiment provides a technical solution: an auxiliary material addition and mixing device for refractory brick production, including an auxiliary addition cylinder 1, a feeding pipe at the feeding port of the auxiliary addition cylinder 1, the auxiliary addition cylinder 1 can be installed to the next process through the flange at its lower end, a control switch group 6 is provided on the outer arc surface of the auxiliary addition cylinder 1, the input end of the control switch group 6 is electrically connected to an external power supply, a gate valve 5 is connected in series at the lower end of the auxiliary addition cylinder 1, the input end of the gate valve 5 is electrically connected to the output end of the control switch group 6, and a mixing mechanism 2 is also included. Mixing mechanism 2: It includes a mounting plate 21, a main mixing rod 22, a secondary mixing rod 23, a drive rod 27, and a passive rod 28. The mounting plate 21 is rotatably connected to the upper inner end of the auxiliary adding cylinder 1. The mounting plate 21 is rotatably connected to the upper inner end of the auxiliary adding cylinder 1 through a sealed bearing. The main mixing rod 22 is rotatably connected to the middle of the mounting plate 21. The main mixing rod 22 and the middle of the mounting plate 21 are rotatably connected through a sealed bearing. The secondary mixing rod 23 is slidably connected to the mounting holes at the left and right ends of the mounting plate 21. A rubber sleeve is provided between the outer arc surface of the upper end of the secondary mixing rod 23 and the upper side of the mounting plate 21. The drive rod 27 is fixedly connected to the outer arc surface of the lower end of the main mixing rod 22. A first inclined surface 271 is opened on the upper side of the rear end of the drive rod 27. The moving rods 28 are all fixedly connected to the lower outer arc surface of the auxiliary mixing rod 23. The lower side of the passive rods 28 are all provided with a second inclined surface 281. The second inclined surface 281 is used in conjunction with the first inclined surface 271. The lowermost ends of the main mixing rod 22 and the auxiliary mixing rod 23 are higher than the upper end of the gate valve 5. The lower outer arc surfaces of the main mixing rod 22 and the auxiliary mixing rod 23 are all fixedly connected with spiral stirring blades. When the main mixing rod 22 rotates, the first inclined surface 271 of the lower driving rod 27 and the second inclined surface 281 of the lower passive rod 28 of the auxiliary mixing rod 23 intermittently contact and slide together, generating thrust to make the auxiliary mixing rod 23 reciprocate up and down in the mounting hole of the mounting plate 21, and at the same time make a circular motion with the mounting plate 21 to ensure that the auxiliary materials in the auxiliary addition cylinder 1 are evenly mixed. The mixing mechanism 2 also includes a driven gear 25 and an internal gear ring 26. The driven gear 25 is rotatably connected to the top wall of the auxiliary adding cylinder 1 via a rotating shaft. The internal gear ring 26 is fixedly connected to the upper side of the mounting plate 21 and meshes with the driven gear 25. The mixing mechanism 2 also includes a gear 24. The gear 24 is fixedly connected to the upper outer arc surface of the main mixing rod 22 and meshes with the driven gear 25. The gear 24, driven gear 25 and internal gear ring 26 are all located inside the sealed space formed between the upper side of the mounting plate 21 and the upper inner end of the auxiliary adding cylinder 1. This sealed space provides a protective base for the gear 24, driven gear 25 and internal gear ring 26, preventing objects that may cause damage to these transmission components from contacting the transmission components. When the main mixing rod 22 rotates clockwise, the gear 24 at the upper end of the main mixing rod 22 rotates synchronously. Through meshing with the driven gear 25, it drives the internal gear ring 26 and the fixed mounting plate 21 to rotate counterclockwise. The mixing mechanism 2 also includes a motor 29, which is mounted on the upper side of the auxiliary adding cylinder 1. The output shaft of the motor 29 is fixedly connected to the center of the upper end face of the main mixing rod 22. The input end of the motor 29 is electrically connected to the output end of the control switch group 6. When the control switch group 6 is started, the output shaft of the motor 29 can drive the main mixing rod 22 to rotate clockwise. A stainless steel mesh frame 3 is installed at the lower end of the auxiliary material addition cylinder 1. The upper side of the stainless steel mesh frame 3 is fixedly connected with evenly distributed conical protrusions 4. After the auxiliary material is mixed in the auxiliary material addition cylinder 1, the gate valve 5 is activated by the control switch group 6. The gate of the gate valve 5 opens, and the mixed auxiliary material is discharged from the lower end of the auxiliary material addition cylinder 1 and flows to the stainless steel mesh frame 3 below. When the mixed auxiliary material flows through the stainless steel mesh frame 3, the mesh structure can divert the mixed auxiliary material. At the same time, the evenly distributed conical protrusions 4 on the stainless steel mesh frame 3 can further divert the material and prevent the auxiliary material from accumulating due to gravity when discharging. This ensures that the material passes through the stainless steel mesh frame 3 in a dispersed manner. After being dispersed by the stainless steel mesh frame 3, the auxiliary material is discharged from the bottom of the auxiliary material addition cylinder 1 and enters the next process of refractory brick production, such as refractory brick production mixing, raw material proportioning, and pressing molding.

[0016] The working principle of the auxiliary material addition and mixing device for refractory brick production provided by this utility model is as follows: Auxiliary materials required for refractory brick production, such as granular auxiliary materials like dextrin and sodium carboxymethyl cellulose, are fed into the auxiliary addition cylinder 1 through the feeding pipe. Then, the control switch group 6 is activated, and the output shaft of the motor 29 drives the main mixing rod 22 to rotate clockwise. The gear 24 at the upper end of the main mixing rod 22 rotates synchronously. Through meshing with the driven gear 25, it drives the internal gear ring 26 and the fixed mounting plate 21 to rotate counterclockwise. When the main mixing rod 22 rotates, the first inclined surface 271 of the lower driving rod 27 intermittently contacts and slides against the second inclined surface 281 of the lower passive rod 28 of the auxiliary mixing rod 23, generating thrust that causes the auxiliary mixing rod 23 to reciprocate up and down within the mounting hole of the mounting plate 21. Simultaneously, the auxiliary mixing rod 23 moves up and down in conjunction with the mounting plate 21. The loading plate 21 makes a circular motion to ensure that the auxiliary materials in the auxiliary addition cylinder 1 are evenly mixed. After the auxiliary materials are mixed in the auxiliary addition cylinder 1, the gate valve 5 is activated by the control switch group 6. The gate of the gate valve 5 opens and the mixed auxiliary materials are discharged from the lower end of the auxiliary addition cylinder 1 and flow to the stainless steel mesh frame 3 below. When the mixed auxiliary materials flow through the stainless steel mesh frame 3, the mesh structure can divert the mixed auxiliary materials. At the same time, the uniform conical protrusions 4 on the stainless steel mesh frame 3 can further divert the materials and prevent the auxiliary materials from accumulating due to gravity when discharging. This ensures that the materials are dispersed through the stainless steel mesh frame 3. After being dispersed by the stainless steel mesh frame 3, the auxiliary materials are discharged from the bottom of the auxiliary addition cylinder 1 and enter the next process of refractory brick production, such as refractory brick production mixing, raw material proportioning, and pressing molding.

[0017] It is worth noting that the motor 29 disclosed in the above embodiments can be model YVP200L1-6, the gate valve 5 can be model DZ971X-10P, and the control switch group 6 is provided with control buttons that correspond one-to-one with the motor 29 and the gate valve 5 and are used to control their switching.
