Description

Technical Field

[0001] The present invention relates to a technical field related to refractory material preparation, and in particular to a multi-form raw material mixing device for refractory material preparation. Background Art

[0002] In the relevant technology, the refractory performance of refractory materials will directly affect the operating safety and service life of high-temperature industrial equipment. In the production process of refractory materials, in order to ensure the stability and reliability of the use of recycled refractory materials, it is generally necessary to undergo multiple mixing and homogenization operations, in which the mixing and homogenization process mainly involves stirring and mixing various types of raw materials (such as powder or granular materials, etc.) through a mixing device.

[0003] However, some raw materials are aggregates obtained by crushing ore. During the crushing process, it is difficult to accurately ensure the uniformity of the output particles, which leads to differences in the particle sizes of aggregates from different batches. When using existing mixing devices to mix and homogenize aggregates of different particle sizes, the existing mixing device has a single stirring speed, which will lead to the problem of mismatch between the stirring speed and the particle size and quality of the raw materials, affecting the uniformity of the raw materials. In addition, there may be uneven particle sizes between different raw materials. Due to the limitations of existing mixing devices, the uniformity of mixing will be aggravated. The resulting uneven mixed materials will reduce the performance of the refractory materials and affect their stability and durability in high temperature environments. Summary of the invention

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0062] The present invention provides a multi-form raw material mixing device for preparing refractory materials, such as Figure 1-Figure 3 As shown, the mixing device includes a feeding component 100 , a mixing component 700 , a rotary conveying component and a receiving component 400 .

[0063] like Figure 3 and Fig.13 As shown, the feed assembly 100 is provided with a discharge port for outputting raw materials. Based on the improved feed assembly 100, different raw materials can be classified and output, such as: according to the different categories and particle sizes, the raw materials are respectively delivered from the corresponding discharge ports to the mixing assembly 700, and the quality of the output of different categories of raw materials can be controlled through different discharge ports. Based on the feed assembly 100, it is convenient to accurately control the ratio of different categories of raw materials in each portion of raw materials (i.e., raw materials delivered to a mixing assembly 700), thereby improving the overall mixing quality.

[0064] like Figure 3 and Figure 4 As shown, the rotary conveying assembly is used to drive the mixing assembly 700 to move along a preset rotary path. Exemplarily, the rotary conveying assembly can use a conveyor belt 600 and be equipped with a corresponding motor 300 and a power roller 500 to form a rotary path to convey the mixing assembly 700. After the mixing assembly 700 is fixed on the conveyor belt 600, an appropriate section can be determined in the rotary conveying path, which is the two working positions of the mixing assembly 700, namely, the raw material receiving position and the raw material dumping position.

[0065] like Figure 3 As shown, the material collecting component 400 is used to collect the mixed material obtained after being stirred by the mixing component 700. Exemplarily, the material collecting component 400 can be a material collecting trough with an opening facing upward, which is used to collect the mixed material poured out by the mixing component 700 at an appropriate position.

[0066] like Figure 3-Figure 7As shown, the mixing assembly 700 is arranged on the rotary conveying assembly and can move with the rotary conveying assembly. The mixing assembly 700 includes a transfer bin, a stirring mechanism, a driving mechanism 740 and a transmission mechanism. The transfer bin is used to hold raw materials, and the transfer bin has: a material receiving position corresponding to the discharge port below and a material pouring position corresponding to the material receiving assembly 400 above on its moving path, wherein the capacity of the transfer bin can be increased during its material receiving and stirring process, and can automatically restore to the original capacity after the mixed material is poured. The stirring mechanism is arranged in the transfer bin for stirring the raw materials. The driving mechanism 740 is provided with an output shaft 741, which can drive the stirring mechanism to rotate. The transmission mechanism is used to match and connect the stirring mechanism with the corresponding driving position of the output shaft 741 as the capacity of the transfer bin changes, so that the driving mechanism 740 drives the stirring mechanism to stir the raw materials at a corresponding speed. In order to improve the mixing efficiency of the raw materials, a plurality of mixing assemblies 700 can be arranged on the rotary conveying assembly, wherein the number of the mixing assemblies 700 can be determined according to factors such as the length and width of the conveyor belt 600 and the efficiency of the feeding assembly 100, which will not be repeated here.

[0067] In this embodiment, Figure 1-Figure 7As shown, the mixing device also includes a housing 200. Three upper, middle and lower working areas are formed in the housing 200, and the feed assembly 100, the rotary conveying assembly and the receiving assembly 400 are arranged in the corresponding working areas from top to bottom, wherein the mixing assembly 700 is fixed on the rotary conveying assembly so that the mixing assembly 700 can move with the rotary conveying assembly. When the transfer bin of the mixing assembly 700 moves to the receiving position, its transfer bin opening faces upward, just corresponding to the discharge port of the feed assembly 100. At this time, the feed assembly 100 cooperates with the mixing assembly 700 to discharge the material. Since the feed assembly 100 can screen the raw materials and control the quality of the large-particle raw materials and small-particle raw materials output, at this time, one mixing assembly 700 outputs a portion of raw materials. When the mixing component 700 receives the raw materials, its internal stirring mechanism also stirs at the corresponding initial speed. As the amount of raw materials received increases, the capacity of the transfer bin will also increase under the action of multiple internal external forces, and the stirring speed needs to be increased. At this time, the transmission mechanism can be linked to cooperate with the change in the capacity of the transfer bin, and the stirring mechanism is matched and connected with the drive position of the output shaft 741 that is adapted to the current capacity. This process realizes the refined stirring of the raw materials inside the mixing component 700, so that the particle size of the mixed raw materials is more uniform. As the rotary conveying component drives the mixing component 700 to continue to move, the mixing component 700 can be moved to the pouring position. Taking the transmission belt as an example, the pouring position can be regarded as the position where the opening of the transfer bin begins to tilt until it faces downward, so that the corresponding receiving component 400 below can completely receive the mixed material in the mixing component 700. At this point, the material receiving component 400 has received a portion of mixed material, and the mixing component 700 continues to move with the rotary conveying component. Before moving to the material receiving position, the transfer bin can be restored to its original capacity under the action of gravity or corresponding external force, and continue to receive raw materials for mixing, and the cycle continues to enter the next transfer process.

[0068] In some optional ways, considering that the transfer bin is a capacity-adjustable structure, which can be linked with the transmission mechanism, the peripheral side wall of the transfer bin can be formed by multiple movable curved plates and movably connected with the transmission mechanism. Figure 5-Figure 9 As shown, the transfer bin includes a plurality of panels 720, which are connected together to form a cylindrical structure, wherein each panel 720 is provided with a slider 721, and two adjacent panels 720 are slidably connected to each other so that each panel 720 can move along the radial direction of the cylindrical structure. Correspondingly, the mixing assembly 700 also includes a fixed base 710, which is connected to the rotary conveying assembly, and the fixed base 710 forms the inner bottom of the transfer bin, wherein the inner bottom is provided with a plurality of chute grooves 711 corresponding to the moving directions of the plurality of panels 720, and the chute grooves 711 are slidably connected to the slider 721.

[0069] Alternatively, if Fig. 9As shown, the transfer warehouse includes four panels 720, each of which is an "L"-shaped bent plate. Correspondingly, four slide grooves 711 are arranged on the fixed base 710. Among them, the multiple panels 720 surround a square cylindrical structure, and the four slide grooves 711 correspond to the four vertices of the square cylindrical structure, and are opened along the direction of the line connecting the corresponding vertex and the center, as shown in FIG. Figure 5 The plate edges of two adjacent panels 720 need to partially overlap, so that when the sliders 721 of the four panels 720 slide along the corresponding slide grooves 711 to increase the capacity of the transfer bin, the four panels 720 can still form a complete cylindrical structure on the fixed base 710.

[0070] Further optionally, in order to prevent the enclosing plate 720 from being too loose at its starting position and end position when the enclosing plate 720 and the chute 711 move relative to each other, thereby affecting the mixing efficiency, the slider 721 of the enclosing plate 720 may be optimized. Exemplarily, the chute 711 is provided with a limiting groove 712 corresponding to the starting position and the end position of the moving path of the corresponding enclosing plate 720; the slider 721 includes a main body block and a telescopic block that is telescopically arranged on the main body block, and the telescopic block cooperates with the limiting groove 712 to limit the enclosing plate 720.

[0071] When the enclosure 720 is in the starting position, the amount of raw materials put into it is small, and the stirring speed is relatively low at this time. By using the telescopic block in cooperation with the limit groove 712 corresponding to the starting position, the transfer bin can be temporarily maintained at a small capacity state, so that the stirring efficiency and stirring effect of the stirring mechanism in the transfer bin are higher. When the enclosure 720 is in the terminal position, it indicates that the amount of raw materials put into it is large, and the stirring speed is relatively fast at this time. By using the telescopic block in cooperation with the limit groove 712 corresponding to the terminal position, the enclosure 720 can be prevented from oscillating during the stirring process, so that the transfer bin can be temporarily maintained at a large capacity state, thereby ensuring the stirring efficiency and stirring effect of the stirring mechanism in the transfer bin.

[0072] The retractable design of the telescopic block enables it to have two states, namely: it can be stuck with the limit groove 712 when extended, and it can be separated from the limit groove 712 when retracted. Correspondingly, during the feeding and stirring process of the transfer bin, the telescopic block needs to be engaged with the limit groove 712, but in order to avoid the two being stuck and affecting the expansion of the transfer bin capacity, the structure of the telescopic block can be optimized. Exemplarily, the telescopic block adopts a wedge-shaped structure, wherein the end with a smaller cross-section of the wedge-shaped structure is arranged toward the bottom of the chute 711.

[0073] Specifically, taking the process of loading and mixing raw materials in the transfer bin as an example, initially the transfer bin opening is facing upwards, and the telescopic block extends out of the main block under the action of gravity. At this time, the slider 721 and the enclosure 720 are limited in the starting position by the telescopic block and the limiting groove 712. Since the telescopic block is designed as a wedge-shaped structure, when the transfer bin receives materials and stirs them through the stirring mechanism, the inner side of the enclosure 720 is subjected to external force, which can make the telescopic block also receive a certain force in the direction along the opening of the chute 711. When the force received by the telescopic block reaches a certain critical value, the telescopic block can be retracted into the main block. At this time, the enclosure 720 can slide freely in the chute 711 until the slider 721 moves to the end position, and the telescopic block and the limiting groove 712 corresponding to the end position cooperate to limit the enclosure 720. When the transfer bin has finished dumping the mixed materials, the transfer bin opening is also facing downwards at this time. Under the action of gravity, the telescopic block and the limiting groove 712 corresponding to the end position can automatically complete the separation process.

[0074] In some optional embodiments, in order to make the stirring speed of the stirring mechanism match the amount of raw materials in the transfer bin and enable the stirring mechanism to stir the raw materials in the transfer bin at different speeds, a plurality of driving positions may be divided on the output shaft 741 and equipped with a switching member for speed switching. Figure 7-Figure 11 As shown, the corresponding driving position of the output shaft 741 includes: a direct transmission part formed at the end of the output shaft 741, and a planetary gear transmission part formed in the middle of the output shaft 741. One end of the transmission mechanism is slidably connected with two adjacent enclosures 720 to form a transfer bin wall; the other end of the transmission mechanism is provided with a switching member, which is used to switch the stirring mechanism with one of the direct transmission part and the speed reduction component of the planetary gear transmission part, and the speed reduction component is used to reduce the output speed of the planetary gear transmission part.

[0075] Since the movement of the enclosure 720 is related to the lateral pressure it receives, specifically: when the proportion of small particles in the raw materials collected in the transfer bin is relatively large, the small particles have smaller gaps and the height of the accumulation in the transfer bin is relatively low, and the lateral pressure received by the enclosure 720 is relatively small; when the proportion of large particles in the raw materials collected in the transfer bin is relatively large, the gaps between the large particles are relatively large and the height of the accumulation in the transfer bin is relatively high, and the lateral pressure received by the enclosure 720 is relatively large. Based on this, it can be seen that the capacity of the transfer bin can reflect the corresponding relationship between the quality of the raw materials and the particle size. In this embodiment, the movement of the enclosure 720 directly acts on the transmission mechanism, and then the corresponding switching member is used to switch and control the stirring mechanism and the corresponding transmission part (direct transmission part and planetary gear transmission part). This design is not only ingenious in structure, but also can accurately adapt to the change of the transfer bin capacity, so that the stirring of the raw materials is more uniform.

[0076] In some optional ways, such as Fig.14As shown, the stirring mechanism includes: a rotating sleeve 750 and a stirring plate 753. The rotating sleeve 750 is rotatably arranged on the outer peripheral side of the output shaft 741, and a switching member installation groove is provided on the outer peripheral side of the rotating sleeve 750, and the switching member installation groove is used to install the switching member; the stirring plate 753 is arranged on the outer peripheral side of the rotating sleeve 750, and the stirring plate 753 can rotate with the rotating sleeve 750 to stir the raw materials.

[0077] The rotating sleeve 750 is a circular sleeve. After the rotating sleeve 750 is sleeved on the outside of the output shaft 741, an annular area for caching raw materials is formed between the rotating sleeve 750 and the enclosure 720. Under the action of the driving mechanism 740 and the transmission mechanism, the rotating sleeve 750 can rotate together with the output shaft 741. Through the stirring plates 753 evenly arranged on the outer circumference of the rotating sleeve 750, different types of raw materials in the annular area between the rotating sleeve 750 and the transfer bin can be stirred and evenly mixed.

[0078] Further optionally, considering that the capacity of the transfer bin is variable, the structure of the stirring plate 753 may be optimized to improve the stirring effect and make the mixed material more uniform. Fig.14 As shown, the stirring mechanism also includes a telescopic stirring plate 754, wherein the telescopic stirring plate 754 is arranged on the stirring plate 753, and the telescopic stirring plate 754 can be telescoped as the capacity of the transfer bin changes.

[0079] In some optional ways, in order to realize the switchable connection between the stirring mechanism and different transmission parts (direct transmission part and planetary gear transmission part) by the switching member, it can be realized by respectively opening a card slot on the corresponding transmission part and the rotating sleeve 750, and the switching member is designed as a card block with adjustable position to cooperate with the card slot. Figure 7-Figure 11 As shown, the speed reduction assembly includes a planetary gear 713 and a sun gear 730, wherein the planetary gear 713 is arranged on the circumferential side of the middle part of the output shaft 741, and the sun gear 730 is sleeved on the outer circumferential side of the planetary gear 713, wherein the circumferential side of the sun gear 730 is provided with a first card slot 731 corresponding to the lower part of the switching member mounting slot; and the circumferential side of the direct transmission part is provided with a second card slot 742 corresponding to the upper part of the switching member mounting slot. Correspondingly, a connecting shaft 752 is provided in the switching member installation groove, and the switching member includes: a telescopic hinge rod 773, a first clamping block 772 and a second clamping block 774, and the middle part of the telescopic hinge rod 773 is rotatably set on the connecting shaft 752; the lower end of the first clamping block 772 is hinged to the upper end of the telescopic hinge rod 773, and along the radial direction of the rotating sleeve 750, the first clamping block 772 can be slidably set in the upper cavity formed by the second clamping slot 742 and the upper part of the switching member installation groove; the upper end of the second clamping block 774 is hinged to the lower end of the telescopic hinge rod 773, and along the radial direction of the rotating sleeve 750, the second clamping block 774 can be slidably set in the lower cavity formed by the first clamping slot 731 and the lower part of the switching member installation groove.

[0080] Further optionally, corresponding transverse grooves 751 are respectively provided at the upper and lower parts of the switching member installation groove, and the transverse grooves 751 are used to guide the first clamping block 772 and the second clamping block 774 respectively, thereby improving the switching efficiency of the switching member.

[0081] In some optional ways, such as Figure 5-Figure 11 , Fig.15 As shown, the transmission mechanism includes a connecting ring 760 , a telescopic rod 761 , a limit block 762 and a synchronization ring 770 .

[0082] A center ring sleeve 763 is provided at the center of the connecting ring 760, and the connecting ring 760 is sleeved on the end of the output shaft 741 through the center ring sleeve 763, wherein the connecting ring 760 can rotate relative to the output shaft 741, and the connecting ring 760 can slide along the axis direction of the output shaft 741. One end of the telescopic rod 761 is connected to the connecting ring 760, and the other end is slidably connected to the transfer warehouse wall formed by two adjacent panels 720 through a limit block 762. The synchronous ring 770 is rotatably arranged on the center ring sleeve 763, wherein the synchronous ring 770 can rotate synchronously with the output shaft 741, and under the limiting action of the center ring sleeve 763, the synchronous ring 770 can move synchronously with the connecting ring 760 along the axis direction of the output shaft 741, and a wedge block 771 is provided on the synchronous ring 770, and the wedge block 771 is used to adjust the position of the first clamping block 772, so as to control the switching member to switch the stirring mechanism with one of the speed reduction components of the direct transmission part and the planetary gear transmission part.

This design method can not only improve the structural stability of the transfer bin through the limit blocks 762, but also realize the sliding connection between the transmission mechanism and the transfer bin. When the capacity of the transfer bin changes, it can directly act on the transmission mechanism, and the switching timing is more accurate, so as to ensure that the stirring speed of the stirring mechanism can be adapted to the quality and particle size of the raw materials in the transfer bin.

Initially, the slider 721 is stuck in the limit groove 712 corresponding to the starting position. The middle part of the output shaft 741, the planetary gear and the sun gear 730 constitute a planetary gear structure.

[0085] In some optional ways, such as Fig.13 As shown, the feed assembly 100 includes: a first raw material separation port and a second raw material separation port. The first raw material separation port and the second raw material separation port are respectively screened out by a screen 101 to obtain two types of raw materials with different sizes of particles. A first screen arranged obliquely relative to the horizontal direction is provided in the first raw material separation port, and a first discharge port 102 and a second discharge port are provided on the lower side of the first screen. The first discharge port 102 is used to output the large particle part of the first raw material on the upper side of the screen, and the second discharge port is used to output the small particle part of the first raw material on the lower side of the screen. A second screen arranged obliquely relative to the horizontal direction is provided in the second raw material separation port, and a third discharge port and a fourth discharge port 104 are provided on the lower side of the second screen. The third discharge port is used to output the large particle part of the second raw material on the upper side of the screen, and the fourth discharge port 104 is used to output the small particle part of the second raw material on the lower side of the screen. Among them, a discharge auger 110 is provided in the first discharge port 102, the second discharge port, the third discharge port and the fourth discharge port 104 respectively, and the discharge auger 110 is used to control the quality of the raw materials output through the corresponding discharge port.

[0086] Optionally, four discharge ports are correspondingly arranged below the feed assembly 100, and each is equipped with a corresponding sensor to detect the output amount. The sensor can detect the ratio of the large particle portion of the first raw material, the small particle portion of the first raw material, the large particle portion of the second raw material, and the small particle portion of the second raw material, and the amount of the output raw material can be accurately controlled based on the detection result. In addition, a guide plate 103 can be arranged under the corresponding screen to guide the small particle raw material screened out to facilitate transportation to the second discharge port and the fourth discharge port 104.

[0087] Combine the following Figure 1-Figure 15 , taking two different types of aggregates as an example, the working principle of a mixing device in this embodiment is specifically described.

[0088] Specifically, the mixing component 700 moves with the rotary conveying component, and when the transfer bin port faces upward and corresponds to the receiving position, the material is fed through the feeding component 100. Since the same type of aggregate can be screened into two types of large and small after passing through the corresponding raw material separation port, four groups of aggregates can be obtained after the two different types of aggregates are screened at the two raw material separation ports, and finally discharged from four corresponding discharge ports. A weight sensor is provided on each discharge port to detect the mass ratio after classification, and then the discharge ratio is automatically controlled based on the corresponding control unit, so that the aggregates collected by the mixing component 700 each time are mixed according to the above mass ratio.

[0089] During the material collection process, when the aggregate collected by the same mixing assembly 700 has a large proportion of small particles, the small particles have a small gap, and the height of the accumulation in the enclosure 720 is low. The lateral pressure on the enclosure 720 is small, and the slider 721 will not slide relative to the slide 711, so that the capacity of the early transfer bin remains unchanged; accordingly, the tension of the enclosure 720 on the telescopic rod 761 remains unchanged, and the connecting ring 760 and the synchronous ring 770 will not move along the axis of the output shaft 741. The first block 772 is stuck on the inside of the rotating sleeve 750, and the second block 774 is stuck on the sun gear 730. The planetary gear transmission part drives the rotating sleeve 750 to rotate, that is, maintains the initial state, and the rotating sleeve 750 continues to rotate with the sun gear 730. Under the deceleration effect of the planetary gear, the speed can be reduced and the distance can be increased to ensure the power of mixing.

[0090] When the aggregate collected by the same mixing assembly 700 accounts for a large proportion of large particles, the aggregate is piled high in the transfer bin due to the large gaps between the large particles, and the side pressure on the enclosure 720 is relatively large. When the aggregate pile reaches a certain height, the enclosure 720 will drive the slider 721 to overcome the limiting effect of the limiting groove 712 and start to slide along the slide groove 711; as the enclosure 720 moves, under the tension of the enclosure 720, the tension on the telescopic rod 761 increases, so that the spring in the telescopic rod 761 is stretched, and under the tension of the enclosure 720, the telescopic rod 761 further drives the connecting ring 760 to move downward along the axis of the output shaft 741, thereby driving the synchronous ring 770 to move downward. At this time, the wedge block 771 on the synchronous ring 770 squeezes the first clamping block 772 on the upper part. Under the action of the squeezing force, the first clamping block 772 moves along the radial direction of the rotating sleeve 750 to the side close to the output shaft 741, and the second clamping block 774 moves along the radial direction of the rotating sleeve 750 to the side away from the sun gear 730 under the action of the telescopic hinge rod 773; as the movement continues, the first clamping block 772 withdraws from the engagement with the rotating sleeve 750 and begins to engage with the second clamping groove 742, and the second clamping block 774 withdraws from the engagement with the sun gear 730 and begins to engage with the inner side of the rotating sleeve 750, and the rotating sleeve 750 is driven to rotate by the direct transmission part until the enclosure 720 drives the slider 721 to move to the limit groove corresponding to the end position, the telescopic block of the slider 721 extends out under the action of gravity, and cooperates with the limit groove to limit the movement of the enclosure 720, corresponding to Figure 7 The status shown is switched to Fig.11 In the state shown, since the bottom area increases after the enclosure 720 moves, the resistance to stirring the raw materials is smaller at this time, so the stirring is switched to a faster speed to improve the stirring quality.

[0091] When the mixing assembly 700 rotates to the pouring position to discharge the material, the transfer bin opening is facing downward, and the telescopic block in the slider 721 is retracted under the action of gravity. As the telescopic block is retracted, the limiting relationship between the slider 721 of the enclosure 720 and the limiting groove 712 at the end position is automatically released, and then it is reset to the initial state.

[0092] The mixing device can continuously mix in batches by detecting the ratio of large and small particles in the raw materials, and evenly divide the raw materials into several small portions, thereby achieving uniform mixing of the raw materials, and can also achieve continuous mixing. The mixing component 700 in the mixing device can automatically adjust the mixing space according to the proportion of large and small particles, and then adaptively adjust the mixing method according to different situations. In case of a large proportion of small particles, the method of aggregating and mixing the raw materials is adopted to ensure the uniformity of the mixing, and the power of the mixing is ensured by reducing the speed and increasing the distance; in case of a large proportion of large particles, the method of allocating the raw materials is adopted, and the speed increasing method is adopted to ensure the uniformity of the mixing.

[0093] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
