Description

Technical Field

[0001] The present application relates to the field of drying equipment, and in particular to a coating drying equipment. Background Art

[0002] Typically, sintering grates are installed on a sintering trolley to support the material and provide ventilation through the gaps between the grates, a key component in the sintering process. A sintering machine of varying models may require tens to hundreds of thousands of grates at a time. Their primary function is to channel the high-temperature, dust-laden exhaust gases generated during the sintering process, which occurs in a high-temperature, highly oxidizing atmosphere.

[0003] During the grate production process, foam sheets are cut into the desired grate shape, connected to hooks, and then immersed in the clay, coating the entire surface. The clay-coated grate bars are then hung on a frame using hooks and fed into a drying machine for drying and forming a mold. After drying, the hooks and foam sheets are removed. The connection between the hooks and the foam sheet forms the mold's riser, through which the molding compound is poured. Finally, the grate bars undergo heat treatment and polishing to form the final grate bars.

[0004] However, the clay is very sticky when wet. When the foam board covered with clay is hung up and sent to the drying equipment, the clay will accumulate at the bottom of the foam board due to gravity when hanging. At this time, the foam board covered with clay directly enters the drying equipment for drying, which will result in a low yield of the mold. Summary of the Invention

[0005] In order to improve the yield rate of molds, the present application provides a coating and drying equipment.

[0006] The coating drying equipment provided in this application adopts the following technical solution: A coating drying equipment includes a drying chamber and a conveying mechanism for conveying workpieces, a plurality of hanging rods that move with the conveying mechanism are installed on the conveying mechanism, and each hanging rod is used to hang the workpiece, one end of the drying chamber is set as a feed port, and a receiving plate is provided at the feed port, a transmission spring is fixedly connected between the receiving plate and the drying chamber, and a knocking rod for knocking off the mud accumulated at the bottom end of the workpiece is fixedly connected to the bottom end of the receiving plate, and an elastic sheet for moving the receiving plate is fixedly connected to each of the hanging rods.

[0007] By employing this technical solution, accumulated clay can be effectively removed from the bottom of the workpiece before it enters the drying chamber, preventing it from affecting subsequent drying and improving the mold's yield rate. Specifically, the elastic plate on the hooking rod, as it moves with the conveyor mechanism, vibrates the receiving plate, which then knocks clay off the bottom of the workpiece via the knocking rod, improving surface cleanliness and ensuring high-quality coating and drying. Furthermore, the transmission spring dampens the vibration amplitude of the receiving plate, extending the equipment's service life.

[0008] Preferably, two fixed plates are fixedly connected at the feed port, one fixed plate corresponds to a receiving plate, and one end of the transmission spring is fixedly connected to the fixed plate, and the other end is fixedly connected to the receiving plate, and both ends of the hanging rod are fixedly connected with elastic sheets, and each elastic sheet is used to contact the upper end of a corresponding receiving plate.

[0009] By adopting the above technical solution, when the workpiece enters the drying chamber of the coating drying equipment, the elastic sheets at both ends of the hanging rod can contact the upper end of the receiving plate, thereby moving the receiving plate. The receiving plate is connected to the fixed plate via a transmission spring. This structure allows the receiving plate to reset after being moved. When the receiving plate is moved, the knocking rod fixed at its bottom end moves accordingly, thereby knocking off the mud accumulated at the bottom of the workpiece, effectively preventing the mud from affecting the subsequent drying effect. At the same time, by providing two fixed plates corresponding to the two receiving plates, the stability of the structure is further improved, ensuring the reliability and consistency of the knocking rod action.

[0010] Preferably, the conveying mechanism includes two chains passing through the inside of the drying chamber, each chain is fixedly connected to a plurality of mounting blocks, both ends of each hanging rod are overlapped on the two chains, and both ends are provided with mounting grooves, each mounting groove is used to be plugged into the mounting block on the corresponding chain.

[0011] By adopting this technical solution, the ends of the hook rod connect to the mounting blocks on the chain through mounting slots, allowing the hook rod to be stably connected to the two chains and move with the chains. This structural design not only ensures reliable workpiece transportation but also facilitates the installation and removal of the hook rod, improving the maintenance convenience of the equipment. In addition, the mounting slots at both ends of the hook rod, which mate with the mounting blocks on the chain, further enhance the stability of the transportation process, preventing the workpiece from shaking or falling during the drying process, thereby ensuring uniform and reliable drying results.

[0012] Preferably, a receiving box for holding mud is provided at the feed port, the upper end of the receiving box is open, and a guide plate connecting the drying chamber and the opening of the receiving box is provided at the feed port, and the guide plate gradually tilts downward in the direction close to the receiving box.

[0013] By adopting this technical solution, workpieces can be immersed in the receiving box for sludge coating before being mounted, ensuring an even coverage of the workpiece surface. During the conveyance of the coated workpiece, excess sludge slides back into the receiving box along the guide plate, avoiding waste and keeping the equipment clean. Furthermore, the inclined design of the guide plate effectively guides sludge flow, further improving sludge recovery efficiency and reducing production costs.

[0014] Preferably, a water tank is installed on the drying chamber, and a water outlet pipe is fixedly connected to the bottom end of the water tank. The water outlet pipe extends downward to the upper end of the guide plate. A water spray pipe is provided at one end of the guide plate close to the drying chamber. A connecting pipe is fixedly connected between the water spray pipe and the water outlet pipe, and a sealing component for controlling the opening and closing of the connecting pipe is installed on the connecting pipe.

[0015] By adopting the above technical solution, it is possible to achieve automatic cleaning and collection of mud during the coating and drying process. Specifically, with the help of the water storage tank, the water outlet pipe and the water spray pipe, the water flow can be accurately guided to the guide plate, thereby effectively washing away the mud that has fallen off the workpiece and allowing it to flow smoothly into the receiving box for centralized processing. At the same time, through the setting of the blocking component, the opening and closing state of the water flow can be flexibly controlled according to actual needs, which not only improves the degree of automation of the equipment, but also further improves the efficiency of mud cleaning and ensures the cleanliness of the internal environment of the drying room. At the same time, water penetrates into the receiving box along the guide plate, which can replenish the water lost in the receiving box in time.

[0016] Preferably, the sealing assembly includes a sealing plate inserted into the connecting pipe, the upper end of the sealing plate passes through the connecting pipe and is fixedly connected to a connecting rope, a guide wheel is rotatably connected to the feed port of the drying chamber, the connecting rope is wound around the guide wheel and fixedly connected to the knocking rod, and a reset spring is connected between the end of the sealing plate extending out of the connecting pipe and the connecting pipe.

[0017] By employing this technical solution, as the striking rod reciprocates to strike the clay, the connecting rope transmits tension via the guide wheel, driving the blocking plate upward and opening the connecting pipe. Simultaneously, a return spring automatically resets the blocking plate back into the connecting pipe once the tension dissipates, ensuring the connecting pipe's timely closure. This means that the connecting pipe automatically opens and closes as the striking rod strikes the clay, minimizing the risk of excessive water in the receiving box.

[0018] Preferably, each receiving plate is fixedly connected to a guide rod, and the guide rod passes through the corresponding fixing plate and is slidably connected to the fixing plate.

[0019] By adopting this technical solution, the receiving plate can be ensured to move stably in the predetermined direction when moved by the elastic sheet, reducing the risk of the receiving plate deflecting or getting stuck, thereby improving the reliability of the knocking rod in knocking out the mud. The sliding connection between the guide rod and the fixed plate further enhances the smoothness of the receiving plate's movement, helping to extend the service life of the equipment.

[0020] Preferably, a buffer rod is installed at the opening of the receiving box.

[0021] By adopting the above technical solution, the workpiece is immersed in the receiving box and then hung directly above the buffer rod. At this time, a large amount of mud on the workpiece falls on the buffer rod and is diverted, and then falls into the receiving box, reducing the impact force when the mud falls into the receiving box and reducing the occurrence of mud splashing on the workers and the surrounding area.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The workpiece can effectively remove the mud accumulated at the bottom before entering the drying chamber to prevent the mud from affecting the subsequent drying effect and improve the yield of the mold; 2. Able to automatically clean and collect mud during the coating and drying process; 3. Water seeps into the receiving box along the guide plate, which can replenish the water lost in the receiving box in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0028] The embodiment of the present application discloses a coating drying device. Figure 1 and Figure 2 The drying equipment includes a drying chamber 1 and a conveyor mechanism 2 for conveying workpieces. A feed port 11 is located on one side of the drying chamber 1. The conveyor mechanism 2 is equipped with multiple hooking rods 3 that move with the conveyor mechanism 2. Each hooking rod 3 is used to hook a workpiece. A receiving box 4 is located at the feed port 11. The upper end of the receiving box 4 is open and contains clay.

[0029] The foam board connected with the hook is immersed in the mud in the receiving box 4, and then hung on the hanging rod 3 through the hook. Under the drive of the conveying mechanism 2, the foam board coated with mud enters the drying chamber 1 for drying, and leaves the drying chamber 1 from the end of the drying chamber 1 away from the feed port 11.

[0030] A striking mechanism 5 is mounted at the feed port 11, designed to strike the accumulated mud at the bottom of the foam board (hereinafter referred to as the workpiece). This striking mechanism 5 comprises two receiving plates 51, fixedly connected to the feed port 11 and two fixed plates 52. The feed port 11 is located between the two fixed plates 52, with one receiving plate 51 corresponding to each fixed plate 52. A transmission spring 53 is connected between the receiving and fixed plates 51, with one end fixedly connected to the fixed plate 52 and the other end fixedly connected to the receiving plate 51. A guide rod 54 is fixedly connected to each receiving plate 51, extending through the corresponding fixed plate 52 and slidably connected thereto.

[0031] The bottom ends of the two receiving plates 51 are fixedly connected to a knocking rod 55 for knocking off the mud accumulated at the bottom end of the workpiece, and both ends of each hanging rod 3 are fixedly connected to an elastic piece 56 for moving the receiving plate 51.

[0032] When the conveying mechanism 2 drives the hanging rod 3 and the workpiece to move, the elastic piece 56 on the hanging rod 3 drives the receiving plate 51 to move back and forth, thereby driving the knocking rod 55 to move back and forth and knock the mud accumulated under the workpiece, achieving the effect of efficiently removing mud by combining mechanical force and gravity.

[0033] Reference Figure 1 and Figure 2 Both ends of the hook rod 3 are fixedly connected to limit brackets 57. The bottom end of each limit bracket 57 is defined by a mounting slot 571. The bottom end of each limit bracket 57 is fixedly connected to an elastic piece 56. The elastic piece 56 is located above the receiving plate 51 and is used to move the receiving plate 51. When the elastic piece 56 passes over the receiving plate 51, it pushes the receiving plate 51 toward the fixed plate 52 and compresses the transmission spring 53 until the elastic piece 56 is squeezed and deformed, separating from the receiving plate 51. The receiving plate 51 then reciprocates along the expansion and contraction direction of the transmission spring 53.

[0034] The conveying mechanism 2 includes two chains 21 that pass through the interior of the drying chamber 1. Each chain 21 passes through the interior of the drying chamber 1 and returns from the lower end of the drying chamber 1 to the feed port 11. Each chain 21 is meshed with four gears 22, which are used to rotate and are connected to the factory wall outside the drying chamber 1. A drive motor is fixedly connected to the wall, and one of the gears 22 connected to each chain 21 is coaxially fixed to the output shaft of the drive motor. Each chain 21 is fixedly connected to a plurality of mounting blocks 23, and the two ends of each hanging rod 3 are overlapped on the two chains 21, and the mounting groove 571 on the limit frame 57 is clamped and fixed to a corresponding mounting block 23. The chain 21 can optionally use a ball chain 21 to ensure smooth transmission; the mounting block 23 can be designed in a rectangular or circular shape.

[0035] A guide plate 6 is provided at the feed inlet 11 to connect the drying chamber 1 with the opening of the receiving box 4 . The guide plate 6 is gradually inclined downward in the direction close to the receiving box 4 .

[0036] Reference Figure 2 and Figure 3 A water storage tank 7 is mounted on the outer top surface of the drying chamber 1. A water outlet pipe 71 is fixedly connected to the bottom end of the water storage tank 7. The water outlet pipe 71 passes through the top wall of the drying chamber 1 and extends downward to the top of the guide plate 6. A water spray pipe 72 is provided at the feed inlet 11. The water spray pipe 72 is arranged along the width direction of the guide plate 6 and has a plurality of water spray holes formed on the top of the water spray pipe 72. The water spray holes are evenly distributed along the length of the water spray pipe 72.

[0037] A connecting pipe 73 is fixedly connected between the water spray pipe 72 and the water outlet pipe 71 , and a blocking component 8 for controlling the opening and closing of the connecting pipe 73 is installed on the connecting pipe 73 .

[0038] The sealing assembly 8 includes a sealing plate 81 inserted into the connecting pipe 73. The upper end of the sealing plate 81 extends through the connecting pipe 73 and is fixedly connected to a connecting rope 82. The sealing plate 81 is raised and lowered vertically to control the dredging of the connecting pipe 73. A guide wheel 83 is rotatably connected to the feed inlet 11 of the drying chamber 1. The connecting rope 82 is wound around the guide wheel 83 and fixedly connected to the knocking rod 55. A connecting block 84 is fixedly connected to the side wall of the end of the sealing plate 81 that extends out of the connecting pipe 73. A return spring 85 is fixedly connected between the connecting block 84 and the dredging pipe.

[0039] When the knocking rod 55 reciprocates, the knocking rod 55 drives the blocking plate 81 to rise and fall through the connecting rope 82, thereby adjusting the dredging of the connecting pipe 73. When the knocking rod 55 knocks the accumulated mud material and drops it, the connecting pipe 73 is dredged, so that a small amount of water flows out to impact the dropped mud material into the receiving box 4, and at the same time, the receiving box 4 is replenished with water.

[0040] A buffer rod 9 is mounted at the opening of the receiving box 4, either overlapped or bolted to the opening. A workpiece covered in clay is hooked onto the hooking rod 3 directly above the receiving box 4. A large amount of clay then falls down along the workpiece onto the buffer rod 9, where it is then diverted and dropped into the receiving box 4. After the clay at the bottom of the workpiece has initially accumulated and solidified, the conveyor mechanism 2 is activated, driving the workpiece toward the workpiece.

[0041] The working principle of the coating drying equipment of the present embodiment is as follows: when the hook rod 3 moves with the conveying mechanism 2 to the feed port 11, the elastic piece 56 on the hook rod 3 contacts and moves the receiving plate 51, causing the receiving plate 51 to reciprocate under the force of the transmission spring 53, thereby driving the knocking rod 55 to reciprocate and knock the clay material at the bottom of the workpiece. The reciprocating motion of the knocking rod 55 drives the blocking plate 81 to reciprocate up and down via the connecting rope 82 and the return spring 85, thereby controlling the opening and closing of the connecting pipe 73. In this way, the water spray pipe 72 intermittently sprays water onto the guide plate 6, thereby flushing the clay material that has fallen on the guide plate 6 and replenishing water into the receiving box 4.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
