Description

Technical Field

[0001] This application relates to the field of sintering furnace feeding device technology, and in particular to a high-temperature resistant push rod type bidirectional conveying mechanism. Background Technology

[0002] In the field of sintering furnace feeding devices, sintering furnaces are widely used and play a crucial role in the sintering process of various materials. With the development of industrial production, the requirements for the automation and efficiency of sintering furnaces are becoming increasingly stringent. As an important component of the sintering furnace, the performance of the feeding mechanism directly affects the overall processing efficiency and production quality. An efficient feeding mechanism can achieve precise material delivery, reduce the labor intensity of manual operation, and improve the stability and consistency of production, thereby bringing significant economic benefits to industrial production.

[0003] Chinese patent CN221036724U discloses a high-temperature catalyst sintering furnace, relating to the field of catalyst sintering equipment technology. It includes a housing containing a pushing mechanism, a sintering mechanism, and a heat-preserving mechanism. The pushing mechanism pushes the catalyst into the sintering mechanism, which then performs high-temperature sintering of the catalyst. The heat-preserving mechanism maintains the temperature of the sintering mechanism during sintering to increase the sintering speed. The pushing mechanism has a semi-enclosed support box. A servo motor is mounted at one end of the support box, and a lead screw is mounted at the output end of the servo motor. A nut seat is fitted onto the lead screw. A slide rail is located on the sliding surface of the support box at the nut seat. A support shaft is mounted on the nut seat, and a push rod is connected to the support shaft. A material box is located at the end of the push rod away from the support shaft. This mechanical method achieves catalyst delivery, reducing manual labor intensity and ensuring accurate delivery into the furnace.

[0004] The aforementioned technologies have the following drawbacks: they can only achieve feeding from one side, which means that the pushing mechanism will be idle during the non-feeding period of the entire sintering furnace operation, resulting in low utilization. Therefore, improvements are needed. Utility Model Content

[0005] To improve the utilization rate of the conveying mechanism, this application provides a high-temperature resistant push rod type bidirectional conveying mechanism.

[0006] A high-temperature resistant push rod type bidirectional conveying mechanism is installed between two furnace bodies. It includes a frame, a lower bearing seat on the frame, a lower lead screw rotatably mounted on the lower bearing seat, a lower drive for driving the lower lead screw to rotate on the frame, a lower slide rail on the frame, a lower nut seat slidably mounted on the lower slide rail, and the lower lead screw and the lower nut seat are threadedly connected.

[0007] The lower nut seat is connected to a mounting plate at its top;

[0008] The mounting plate is provided with an upper bearing seat, the upper bearing seat is rotatably provided with an upper lead screw, the mounting plate is provided with an upper drive for driving the upper lead screw to rotate, the mounting plate is provided with an upper slide rail, the upper slide rail is slidably provided with an upper nut seat, and the upper lead screw is threadedly connected to the upper nut seat.

[0009] Push rods are provided on both sides of the upper nut seat, and a material box is provided at the end of the push rod.

[0010] By adopting the above technical solution, in the initial state, the lower nut seat and the upper nut seat are located in the middle of the lower slide rail and the upper slide rail, respectively. When it is necessary to feed material to a certain side of the furnace body, the upper drive and the upper drive can be activated simultaneously, causing both the lower nut seat and the upper nut seat to slide towards the furnace body, thereby achieving rapid feeding of the material box on that side. Furthermore, while the material box on that side is being fed into the corresponding side of the furnace body, the other material box is approximately located in the middle of the entire conveying mechanism. This allows for the use of the idle time during feeding on one side to load material into the other material box, preparing for subsequent feeding to the other side of the furnace body. This fully utilizes the conveying mechanism, feeding material to both furnace bodies sequentially, resulting in higher utilization.

[0011] Preferably, both the upper nut seat and the lower nut seat are connected to a brushing mechanism. The brushing mechanism includes a housing, which is connected to the corresponding upper nut seat and lower nut seat. Brushing wires are provided inside the housing, and the brushing wires abut against the corresponding upper screw and lower screw.

[0012] By adopting the above technical solution, the upper nut seat and the lower nut seat are connected to the brushing mechanism. The brushing wires in the brushing mechanism abut against the corresponding lead screw, which can brush the lead screw, ensuring the cleanliness of the lead screw, thereby ensuring the normal operation and service life of the conveying mechanism.

[0013] Preferably, the housing includes an upper half-shell and a lower half-shell, the brush filaments are disposed inside the upper half-shell and the lower half-shell, and the upper half-shell and the lower half-shell are detachably connected.

[0014] By adopting the above technical solution, the dust brushing mechanism connected to the upper and lower nut seats can remove dust from the screw by abutting the brushing wires against the screw. Furthermore, the housing of the dust brushing mechanism is set as a detachable upper and lower half-shell, which facilitates the replacement and maintenance of the brushing wires.

[0015] Preferably, the bottom of the lower shell is provided with several dust collection holes.

[0016] By adopting the above technical solution, the brushing wires of the brushing mechanism can clean the dust on the lead screw by abutting against it; furthermore, the housing is divided into a detachable upper half and a lower half for easy maintenance of the brushing mechanism; in addition, the dust collection hole at the bottom of the lower half allows the brushed dust to fall off, preventing dust from accumulating inside the housing for a long time, and it is also easy to clean the dust after it is discharged.

[0017] Preferably, both the lower slide rail and the upper slide rail are provided with dust collection grooves.

[0018] By adopting the above technical solution, the dust collection hole at the bottom of the lower shell allows the brushed dust to fall off. Furthermore, some of the fallen dust will fall into the lower and upper slide rails. Therefore, this application provides a dust collection groove inside the lower and upper slide rails to collect some of the fallen dust. In particular, during the sliding process of the lower and upper nut seats, when some accumulated dust is located on the side of the lower and upper nut seats, when sliding to the dust collection groove, some of the dust will fall into the dust collection groove, thereby reducing the dust accumulation on the surface of the lower and upper slide rails and reducing the impact of this dust on the sliding of the lower and upper nut seats.

[0019] Preferably, the upper shell is connected to a sliding rod, the lower shell is provided with a sliding hole for the sliding rod to pass through, and the end of the sliding rod extending out of the sliding hole is threadedly connected to a locking nut, the locking nut abutting against the bottom of the lower shell.

[0020] By adopting the above technical solution, the shell of the brushing mechanism is divided into a detachable upper shell and a lower shell, which facilitates the replacement and maintenance of the brushing wires; the sliding rod and the sliding hole are matched and fixed by the locking nut, so that the upper shell and the lower shell can be stably connected.

[0021] Preferably, the slide rod and the slide hole are fitted with a clearance, and a vibration spring is provided between the upper half shell and the lower half shell.

[0022] By adopting the above technical solution, the sliding rod and the sliding hole are fitted with a clearance, and a vibration spring is set between the upper half shell and the lower half shell. This allows the dust brushing mechanism to generate a small vibration during operation, which enhances the dust brushing effect. In addition, it can also promote the discharge of dust from the dust collection hole.

[0023] Preferably, the material box is provided with mounting holes, and the push rod is threadedly connected to the corresponding mounting holes.

[0024] By adopting the above technical solution, the material box is connected to the push rod by a thread through the mounting hole, which facilitates the installation and disassembly of the material box and makes it convenient to replace or maintain the material box.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The two furnace bodies can be fed sequentially. While feeding one side of the material box, the other side of the material box can be loaded during the idle time, thereby improving the utilization rate of the conveying mechanism.

[0027] 2. The brushing bristles of the brushing mechanism abut against the lead screw, which can clean the lead screw;

[0028] 3. The material box and push rod are connected by threads, which facilitates disassembly and installation. Attached Figure Description

[0040] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0041] This application mainly adopts a two-way screw nut structure to drive the feeding scheme of the material boxes on both sides, which achieves the effect of improving the feeding utilization rate of the conveying mechanism between the two furnace bodies. The following is a further detailed description of this application.

[0042] Example

[0043] Reference Figure 1 and Figure 2 The high-temperature resistant pusher 41 bidirectional conveying mechanism provided in this application embodiment is disposed between two furnace bodies 1. It includes a frame 11, a lower conveying structure 2, an upper conveying structure 3, and a feeding structure 4. The frame 11 serves as the supporting foundation for the entire mechanism. The lower conveying structure 2 is mounted on the frame 11. The upper conveying structure 3 is connected to the lower conveying structure 2 via a mounting plate 12. The feeding structure 4 is mounted on the upper conveying structure 3. This hierarchical arrangement and connection relationship enables this application to achieve bidirectional feeding function, improving the utilization rate of the conveying mechanism. Specifically, the lower conveying structure 2 drives the upper conveying structure 3 to move horizontally, and the upper conveying structure 3 then drives the feeding structure 4 to move, thereby accurately delivering materials to one side of the furnace body 1 and making full use of the non-feeding time period on the other side for loading preparation.

[0044] Reference Figure 3Specifically, the lower conveying structure 2 includes a lower bearing seat 21, a lower lead screw 22, a lower drive 23, a lower slide rail 24, and a lower nut seat 25. The lower bearing seat 21 is mounted on the frame 11, providing rotational support for the lower lead screw 22. The lower lead screw 22 is rotatably mounted in the lower bearing seat 21 and is typically a threaded metal rod made of high-strength alloy steel to ensure it will not deform during prolonged use. In other embodiments, other high-temperature resistant materials may also be used. The lower drive 23 is also fixedly connected to the frame 11 and is used to drive the lower lead screw 22 to rotate. The lower drive 23 can be a servo motor, which has the characteristic of precisely controlling speed and angle, enabling accurate rotation of the lower lead screw 22. The lower slide rail 24 is mounted on the frame 11 and can be a rectangular strip-shaped groove. The bottom of the lower nut seat 25 is slidably mounted on the lower slide rail 24, and its middle part is threadedly connected to the lower lead screw 22. When the lower lead screw 22 rotates, the lower nut seat 25 slides along the lower slide rail 24. The lower nut seat 25 is generally a block structure with threaded holes inside that match the lower lead screw 22. It can also be made of alloy steel to ensure the fitting accuracy and wear resistance with the lower lead screw 22. The combination logic of the lower conveying structure 2 is that the lower drive 23 drives the lower lead screw 22 to rotate. The rotation of the lower lead screw 22 is converted into linear motion of the lower nut seat 25 on the lower slide rail 24. This motion mode is stable and precise, enabling accurate control of the position of the upper conveying structure 3.

[0045] Mounting plate 12 is fixedly connected to the top of lower nut seat 25, and upper conveying structure 3 is mounted on mounting plate 12. Specifically, upper conveying structure 3 includes upper bearing seat 31, upper lead screw 32, upper drive 33, upper slide rail 34, and upper nut seat 35. Upper bearing seat 31 is mounted on mounting plate 12, which is connected to the top of lower nut seat 25, so upper bearing seat 31 will move together with lower nut seat 25. Upper lead screw 32 is rotatably disposed in upper bearing seat 31, and its structure and material are similar to lower lead screw 22. Upper drive 33 can also be a servo motor, used to drive upper lead screw 32 to rotate. Upper slide rail 34 is mounted on mounting plate 12, and its structure and material are similar to lower slide rail 24. Upper nut seat 35 is slidably disposed on upper slide rail 34 and threadedly connected to upper lead screw 32. Upper nut seat 35 has a similar shape and material to lower nut seat 25. The combination logic of the upper conveying structure 3 is that the upper drive 33 drives the upper lead screw 32 to rotate. The rotation of the upper lead screw 32 is converted into the linear motion of the upper nut seat 35 on the upper slide rail 34. The upper conveying structure 3 moves together with the lower conveying structure 2, realizing two-stage motion control, so that the feeding structure 4 can be accurately delivered to the designated position.

[0046] Specifically, the feeding structure 4 includes push rods 41 and material boxes 42, with two push rods 41 and two material boxes 42. The two push rods 41 are respectively connected to both sides of the upper nut seat 35. They are generally long rods, made of aluminum alloy, and have a light weight and high strength. The material boxes 42 are located at the ends of the corresponding push rods 41. The material boxes 42 are used to hold materials, and their shape can be designed in different styles according to the characteristics of the materials, such as square or round. The material can be high-temperature resistant stainless steel to adapt to the high-temperature environment of the sintering furnace. The outer wall of the material box 42 is provided with mounting holes 43, and the push rods 41 are threaded into the corresponding mounting holes 43. This connection method facilitates the installation and disassembly of the material box 42, and makes it convenient to clean and replace the material box 42. The combination logic of the feeding structure 4 is that the upper conveying structure 3 drives the push rods 41 and material boxes 42 to move, delivering the material into the furnace body 1, thus realizing the feeding function.

[0047] Reference Figure 3 , Figure 4 and Figure 5 Furthermore, both the upper nut seat 35 and the lower nut seat 25 are connected to a dust brushing mechanism 5, which includes a housing 51 and dust brushing wires 52. The housing 51 is connected to the corresponding upper nut seat 35 and lower nut seat 25, and its function is to protect the dust brushing wires 52 and ensure that they abut against the lead screw. Further, the housing 51 includes an upper half-shell 511 and a lower half-shell 512, which are detachably connected. This design facilitates the replacement and maintenance of the dust brushing wires 52. The dust brushing wires 52 are located inside the upper half-shell 511 and lower half-shell 512, abutting against the corresponding upper and lower lead screws. Their material can be steel wire, effectively removing dust and impurities from the lead screws to ensure their normal operation. Several dust collection holes 53 are provided through the bottom of the lower half-shell 512, allowing dust to fall through and preventing accumulation inside the housing 51. The upper shell 511 is connected to a sliding rod 54, and the lower shell 512 is provided with a sliding hole 55 through which the sliding rod 54 passes. The end of the sliding rod 54 extending out of the sliding hole 55 is threadedly connected to a locking nut 56, which abuts against the bottom of the lower shell 512. By tightening the locking nut 56, the distance between the upper shell 511 and the lower shell 512 can be adjusted, allowing the brushing wires 52 to better contact the lead screw. In addition, there is a clearance fit between the sliding rod 54 and the sliding hole 55, and a vibration spring 57 is provided between the upper shell 511 and the lower shell 512. The vibration spring 57 can cause the brushing wires 52 to vibrate during operation, thereby promoting the discharge of dust from the dust collection hole 53.

[0048] Correspondingly, both the lower slide rail 24 and the upper slide rail 34 are provided with dust collection grooves 58. Some of the falling dust will fall into the interior of the lower slide rail 24 and the upper slide rail 34. Therefore, this application provides dust collection grooves 58 inside the lower slide rail 24 and the upper slide rail 34 to collect some of the falling dust. In particular, during the sliding process of the lower nut seat 25 and the upper nut seat 35, when some dust accumulates on the side of the lower nut seat 25 and the upper nut seat 35, when sliding to the dust collection groove 58, some of the dust will fall into the dust collection groove 58, thereby reducing the dust accumulation on the surface of the lower slide rail 24 and the upper slide rail 34 and reducing the impact of this dust on the sliding of the lower nut seat 25 and the upper nut seat 35.

[0049] The implementation principle of this embodiment is as follows: In the initial state, the lower nut seat 25 and the upper nut seat 35 are located in the middle of the lower slide rail 24 and the upper slide rail 34, respectively. When it is necessary to feed material to a certain side of the furnace body 1, the upper drive 33 and the lower drive 23 are started simultaneously. The lower drive 23 drives the lower lead screw 22 to rotate, causing the lower nut seat 25 to move along the lower slide rail 24. The upper drive 33 drives the upper lead screw 32 to rotate, causing the upper nut seat 35 to move along the upper slide rail 34, thereby moving one side of the material box 42 on both sides to that side of the furnace body 1 for feeding. During the process of feeding material into the furnace body 1 on that side, the other material box 42 is roughly located in the middle of the entire conveying mechanism. At this time, the other material box 42 can be loaded with material to prepare for subsequent feeding to the other side of the furnace body 1. The dust removal mechanism 5 can continuously remove dust from the lead screw during the movement of the nut seat, ensuring the normal operation of the mechanism. This design makes full use of the non-feeding time of the conveying mechanism, improving the utilization rate of the conveying mechanism. At the same time, the setting of the dust brushing mechanism 5 ensures the cleanliness of the lead screw and extends the service life of the mechanism. Compared with the existing conveying mechanism that can only feed material from one side, it has made significant improvements and enhancements.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
