Description

Technical Field

[0001] This utility model relates to the field of chemical machinery processing technology, and more specifically to an enamel tube glaze spraying device. Background Technology

[0002] Enameled pipes are widely used in chemical machinery. Compared to metal pipes, enamel-lined pipes offer superior corrosion resistance, preventing corrosion and oxidation of steel pipes and extending their service life. They also exhibit excellent wear resistance due to their high surface hardness, allowing for long-term use under high temperature and pressure. Furthermore, the enamel material in enamel-lined pipes withstands high temperatures, preventing deformation and cracking, thus ensuring safety. Finally, the steel pipe skeleton of enamel-lined pipes can withstand high pressure without exploding or rupturing.

[0003] Currently, enamel-lined pipes are 2m-3m in length and weigh several hundred kilograms. The enamel coating is applied to the inner wall of the pipe and the flange ends. The specific implementation should follow these steps: 1. Place the pipes individually on the rack with grooves, tilting the pipes. 2. Use compressed air to clean the inner wall and use solvent to wipe and clean the inner wall; 3. Use the nozzle to spray the oil from top to bottom into the inner wall, rotating the nozzle as you spray to ensure that the glaze is applied to all sides of the inner wall. 4. Let it air dry.

[0004] Existing enamel spraying equipment is limited to nozzles and requires manual operation. Besides being inefficient and labor-intensive, it also has the following drawbacks: due to the height of the spray nozzle, it can only be placed at an angle for spraying. Since the enamel is fluid, it inevitably drips onto the lower side of the nozzle wall, resulting in a thicker layer of enamel on that side. This uneven expansion during the enamel firing process can easily lead to enamel chipping. Summary of the Invention

[0005] In order to solve the above problems, the purpose of this utility model is to provide an enamel tube enamel spraying device with a high degree of automation, uniform enamel spraying, reduced labor intensity, and high yield.

[0006] According to one aspect of this utility model, an enamel pipe glaze spraying device is provided, comprising: a base, a column, a first moving component, a second moving component, a first fixing component, a second fixing component, and a glaze spraying component. The bottom of the base is fixed to the ground, the column is vertically fixed to the top of the base, the second moving component is disposed on the first moving component, the glaze spraying component is disposed on the second moving component, the first fixing component and the second fixing component are arranged side by side on both sides of the column, the second moving component drives the glaze spraying component to move above the first fixing component or the second fixing component, and the first moving component drives the glaze spraying component to approach the bottom of the first fixing component or the second fixing component. The first and second moving components enable the glaze spraying component to move up and down and left and right, thereby automatically performing the glaze spraying process on the inner wall of the pipe. The cooperation of the first fixing component, the second fixing component, and the glaze spraying component greatly improves the glaze spraying efficiency, while achieving uniform glaze spraying and low labor intensity.

[0007] In some embodiments, the first moving component includes: a first linear guide, a first slider, a second linear guide, a second slider, a first sliding plate, a first rack, a first gear, and a first motor. The first and second linear guides are mounted on opposite sides of the column. The first slider is sleeved on the first linear guide, and the second slider is sleeved on the second linear guide. The first sliding plate is fixedly connected to the first and second sliders. The first rack is mounted on the column and is parallel to the first and second linear guides. The first motor is mounted on the first sliding plate, and the first gear is mounted on the output end of the first motor, meshing with the first rack. The first motor drives the first sliding plate to reciprocate up and down on the first and second linear guides, enabling the glazing component to move downwards from the top of the tube to spray glaze, preventing uneven glaze application.

[0008] In some implementations, a second movable component is fixedly mounted on the first sliding plate.

[0009] In some embodiments, the second moving component includes: a crossbar, a third linear guide, a third slider, a second sliding plate, a second rack, a second gear, and a second motor. The crossbar is fixedly connected to the first sliding plate. The third linear guide is mounted on the crossbar. The third slider is sleeved on the third linear guide. The second sliding plate is fixedly connected to the third slider. The second rack is mounted on the crossbar and parallel to the third linear guide. The second motor is mounted on the second sliding plate. The output end of the second motor is equipped with a second gear, which meshes with the second rack. The second motor drives the second sliding plate to reciprocate left and right on the third linear guide, thereby enabling the glazing component to move between the first fixed component and the second fixed component.

[0010] In some embodiments, the glazing assembly includes a mounting base, an inlet pipe, an outlet pipe, and a rotary nozzle. The mounting base is fixedly connected to a second sliding plate, the inlet pipe is fixed to the mounting base, one end of the inlet pipe is connected to the glaze tank, the other end of the inlet pipe is connected to the top of the outlet pipe, and the rotary nozzle is disposed at the bottom of the outlet pipe. The rotary nozzle enables uniform spraying of glaze onto the inner wall of the pipe.

[0011] In some implementations, multiple discharge pipes and rotary nozzles are provided. Matching multiple discharge pipes and rotary nozzles with multiple pipes to be processed improves processing efficiency.

[0012] In some embodiments, the first fixing component includes a base, a fixing seat, and a driving member. The base is disposed on the ground, the fixing seat is hinged to the base via a rotating shaft, the bottom of the driving member is mounted on the base, and the output end of the driving member is connected to the fixing seat. The driving member drives the fixing seat to be in a vertical position relative to the base. The vertical position of the fixing seat facilitates the vertical downward flow of the glaze along the pipe wall.

[0013] In some embodiments, the top of the mounting base is provided with several mounting slots, and mounting plates are inserted into the mounting slots to define the position of the enamel tube. The tube is placed through the mounting slots and the mounting plates are used to fix the position of the tube.

[0014] In some implementations, there are 3-6 fixed slots, and the number of discharge pipes and rotating nozzles is the same as the number of fixed slots.

[0015] In some implementations, the structure of the first fixing component is the same as that of the second fixing component.

[0016] This invention offers significant advantages over existing technologies, including high automation, uniform glaze application, reduced labor intensity, and high yield. The first and second moving components enable vertical and horizontal movement of the glazing component, automating the glaze application process on the inner wall of the tube. The coordinated operation of the first and second fixed components and the glazing component greatly improves glazing efficiency while ensuring uniform glaze application and low labor intensity. A first motor drives a first sliding plate to reciprocate vertically along the first and second linear rails, allowing the glazing component to move downwards from the top of the tube, preventing uneven glaze application. A second motor drives a second sliding plate to reciprocate horizontally along the third linear rail, enabling the glazing component to move between the first and second fixed components. A rotating nozzle ensures uniform glaze application on the inner wall of the tube. Multiple discharge pipes and rotating nozzles are matched with multiple tubes to be processed, improving processing efficiency. The fixed base is in a vertical position, facilitating vertical downward flow of the glaze along the tube wall. The tube is placed in a fixed groove and its position is fixed by a fixing plate.

Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0020] like Figure 1 As shown, the enamel pipe glaze spraying device of this utility model includes: a base 1, a column 2, a first moving component 3, a second moving component 4, a first fixing component 5, a second fixing component 6, and a glaze spraying component 7. The base 1 is fixed to the ground at the bottom, the column 2 is vertically fixed to the top of the base 1, the second moving component 4 is disposed on the first moving component 3, and the glaze spraying component 7 is disposed on the second moving component 4. The first fixing component 5 and the second fixing component 6 are arranged side by side on both sides of the column 2. The second moving component 4 drives the glaze spraying component 7 to move above the first fixing component 5 or the second fixing component 6, and the first moving component 3 drives the glaze spraying component 7 to approach the bottom of the first fixing component 5 or the second fixing component 6. The first moving component 3 and the second moving component 4 realize the up-and-down and left-and-right movement of the glaze spraying component 7, thereby automatically performing the glaze spraying process on the inner wall of the pipe. The cooperation of the first fixing component 5, the second fixing component 6, and the glaze spraying component 7 greatly improves the glaze spraying efficiency, while achieving uniform glaze spraying and low labor intensity.

[0021] like Figure 2As shown, the first moving component 3 includes: a first linear guide 31, a first slider 32, a second linear guide 33, a second slider 34, a first sliding plate 35, a first rack 36, a first gear 37, and a first motor 38. The first linear guide 31 and the second linear guide 33 are installed on both sides of the column 2. The first slider 32 is sleeved on the first linear guide 31, and the second slider 34 is sleeved on the second linear guide 33. The first sliding plate 35 is fixedly connected to the first slider 32 and the second slider 34. The first rack 36 is installed on the column 2 and is arranged parallel to the first linear guide 31 and the second linear guide 33. The first motor 38 is installed on the first sliding plate 35, and the first gear 37 is installed at the output end of the first motor 38. The first gear 37 meshes with the first rack 36. The first motor 38 drives the first sliding plate 35 to move up and down on the first linear guide 31 and the second linear guide 33, so that the glazing component 7 moves downward from the top of the tube to spray glaze, preventing uneven glaze application. The first guide rail 31 and the second guide rail 33 are located on the left and right sides of the column 2, which makes the first sliding plate 35 move up and down more smoothly.

[0022] The second moving component 4 is fixedly mounted on the first sliding plate 35.

[0023] The second moving component 4 includes: a crossbar 41, a third linear guide 42, a third slider 43, a second sliding plate 44, a second rack 45, a second gear 46, and a second motor 47. The crossbar 41 is fixedly connected to the first sliding plate 35. The third linear guide 42 is mounted on the crossbar 41. The third slider 43 is sleeved on the third linear guide 42. The second sliding plate 44 is fixedly connected to the third slider 43. The second rack 45 is mounted on the crossbar 41 and is parallel to the third linear guide 42. The second motor 47 is mounted on the second sliding plate 44. The second gear 46 is mounted on the output end of the second motor 47, and the second gear 46 meshes with the second rack 45. The second motor 47 drives the second sliding plate 44 to move left and right reciprocally on the third linear guide 42, thereby enabling the glazing component 7 to move between the first fixed component 5 and the second fixed component 6.

[0024] like Figure 3 As shown, the glazing assembly 7 includes: a mounting base 71, a feed pipe 72, a discharge pipe 73, and a rotary nozzle 74. The mounting base 71 is fixedly connected to the second sliding plate 44. The feed pipe 72 is fixed on the mounting base 71. One end of the feed pipe 72 is connected to the glaze tank, and the other end is connected to the top of the discharge pipe 73. The rotary nozzle 74 is installed at the bottom of the discharge pipe 73. The rotary nozzle 74 enables uniform spraying of glaze onto the inner wall of the pipe.

[0025] Multiple discharge pipes 73 and multiple rotary nozzles 74 are provided. The processing efficiency is improved by matching multiple discharge pipes 73 and multiple rotary nozzles 74 with multiple pipes to be processed.

[0026] like Figure 4As shown, the first fixing component 5 includes a base 51, a fixing seat 52, and a driving member 53. The base 51 is set on the ground, the fixing seat 52 is hinged to the base 51 with a rotating shaft, the bottom of the driving member 53 is mounted on the base 51, and the output end of the driving member 53 is connected to the fixing seat 52. The driving member 53 drives the fixing seat 52 to be in a vertical state with the base 51. The vertical state of the fixing seat 52 facilitates the vertical downward flow of the glaze along the pipe wall.

[0027] When the tube is tilted, a thicker glaze layer will be present on the lower part of the inner wall. When it is vertical, excess glaze will flow out from the tube wall. On the other hand, the glaze will also fall during the top-to-bottom spraying process, resulting in a more uniform overall glaze layer.

[0028] The top of the mounting base 52 is provided with several mounting slots 54, and mounting plates 55 are inserted into the mounting slots 54 to define the position of the enamel tube. The tube is placed through the mounting slots 54 and the mounting plates 55 are used to fix the position of the tube.

[0029] There are 3-6 fixed slots 54, and the number of discharge pipes 73 and rotary nozzles 74 is the same as the number of fixed slots 54. It should also be noted that the spacing between the discharge pipes 73 needs to be consistent with the spacing between the fixed slots 54 to ensure that the rotary nozzles 74 can move axially along the pipe body.

[0030] The structure of the first fixing component 5 is the same as that of the second fixing component 6. On the one hand, eight metal tubes can be installed through the first fixing component 5 and the second fixing component 6, and the glaze can be sprayed on at least six metal tubes each time, which greatly improves the processing efficiency.

[0031] like Figure 5 As shown, the glaze spraying process is as follows: In the first step, the fixing seat 52 in the first fixing component 5 and the second fixing component 6 is in a horizontal state; The second step is to hoist the pipe body into the fixing groove 54 and use the fixing plate 55 to fix the position of the pipe body; Third, the first moving component 3 drives the rotating nozzle 74 to the highest position; Fourth step, the driving component 53 drives the fixed seat 52 and the base 51 to be in a vertical state, and the tube body is in a vertical state. Fifth step, the second moving component 4 drives the rotating nozzle 74 to above the first fixed component 5; Step 6: The first moving component 3 drives the rotating nozzle 74 to the top of the tube; Step 7: While the rotating nozzle 74 is being opened for glazing, the first moving component 3 drives the rotating nozzle 74 to move at a constant speed to the bottom of the tube. Step 8: The first moving component 3 drives the rotating nozzle 74 to move to the highest position; Step 9: The second moving component 4 moves the rotating nozzle 74 above the second fixed component 6; Step 10: The first moving component 3 drives the rotating nozzle 74 to the top of the tube; In the eleventh step, while the rotating nozzle 74 is opened to spray glaze, the first moving component 3 drives the rotating nozzle 74 to move at a constant speed to the bottom of the tube. Step 12: The first moving component 3 drives the rotating nozzle 74 to move to the highest position; Step 13: The tube is kept vertical while waiting for the glaze to dry; Step fourteen: The fixing seat 52 in the first fixing component 5 and the second fixing component 6 returns to a horizontal state; Step 15: Lift the dried glaze tube off the ground and wait for firing.

[0032] Another embodiment of this utility model Considering the drying time of the glaze, a third moving component can be set at the bottom of the base 1, and a third fixed component, a fourth fixed component, etc. can be set accordingly. Multiple fixed components are arranged in a row. After the above operation is completed, the third moving component drives the column 2 and the glazing component 7 to move between the third fixed component and the fourth fixed component, and the above steps are repeated.

[0033] This allows for spraying while waiting for the glaze to dry, improving processing efficiency.

[0034] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
